consents to assignment within 60 days of the Closing Date. With respect to each
Assumed Lease, Seller and Buyer shall execute an Assignment and Assumption of
Lease in the same or substantially the same form of Exhibit 3, attached hereto
and incorporated herein.

documents and information owned by Seller relating to the Business, however
maintained or stored (collectively, the "Records"), it being understood that the
Seller may cause to be deleted confidential information that does not relate to
the Subject Assets or the Business. The Records are made available without
representation by Seller or recourse to Seller, and Buyer relies on such
information at its own risk. Without limiting the generality of the foregoing,
Buyer acknowledges that Seller has made no representations (express or implied)
regarding the accuracy of the Records provided by Seller, the qualifications of
the parties preparing such information, or the conclusions set forth therein.

Liabilities described below, the aggregate consideration for the Subject Assets
(the "Purchase Price") shall be the amount equal to $1.00 (the "Purchase
Price").

1.3 PAYMENT TERMS. The Purchase Price will be payable to Seller by Buyer on the
Closing Date.

1.4 ASSUMED LIABILITIES. As partial consideration for the Subject Assets, Buyer
will assume and agree to pay or perform all of the: (i) liabilities and

"Assumed Liabilities"). Buyer shall not assume or be obligated under, or become
liable for, any debt, liability, or obligation whatsoever of Seller or the
Business arising out of:

                                       3
<PAGE>

(i) any tax liability or obligation relating to transactions or periods prior to
and including the Closing Date (but excluding any sales, use, transfer or other
tax obligation resulting from the transactions contemplated by this Agreement,
which Buyer hereby agrees to be responsible for);
(ii) any liability or obligation to Seller's employees whatsoever, whether for
salaries and wages, sick pay, or any other employee benefit and whether relating
to the termination of their employment or otherwise arising, relating to periods
prior to and including the Closing Date;
(iii) any liability or obligation arising out of the lawsuit filed by Thomas K.
Payne, The Door to the Internet, Inc., and Internet Holdings, Inc., against
Seller, in the 72nd District Court of Lubbock, Texas; or

necessary Lessor consent to the assignment (hereinafter collectively "the
Retained Liabilities").

Regarding current employees, Buyer agrees to adhere to arrangements made with
Seller's current employees regarding continued employment and severance
benefits, specifically:

     o    6 employees, previously identified to Buyer by Seller, have been
          offered employment with the Business through 2/1/07, and Buyer agrees
          to utilize employees until said date;
     o    8 employees, previously identified to Buyer by Seller, have been
          offered employment with the Business through 3/1/07, and Buyer agrees
          to utilize employees until said date;
     o    All employees to receive four weeks of severance pay;
     o    Richard Garner, Supervisor-IT, to receive four weeks of severance pay
          and retention bonus;
     o    All employees eligible for Standard Severance Benefits, including but
          not limited to, 2007 vacation payout, COBRA benefit continuation, and
          outplacement Assistance.

     Employees will remain Seller's employees and will be eligible for all above
     mentioned benefits provided they work until the above-referenced release
     dates. Buyer agrees to only utilize current employees for work performed in
     the ordinary course of the Business until said release dates. These
     arrangements do not constitute Assumed Liabilities on the part of the
     Buyer. Further, Buyer may contact current employees regarding continued
     employment with Buyer to commence after the employee's release date defined
     above, unless said employee chooses to leave prior to his/her release date.

The intention of the parties is that Seller will have no further liability or
obligation regarding the Business, except for the Retained Liabilities, after
the Closing Date, and Buyer agrees to indemnify, protect and hold harmless
Seller and its affiliates and their respective members, managers, shareholders,
directors, officers, employees and agents from any and all damages, losses,
actions, demands, judgments, costs, expenses, claims or other liabilities
arising out of Seller's operation of the Business prior to the Closing Date.

<PAGE>

2.2 SELLER'S OBLIGATIONS. The obligations of Seller include:

Seller shall pay Buyer $825,000 ("the Assumption Cost"); with $500,000 due at
Closing and the remaining $325,000, due on February 28, 2007, as consideration
for the Buyer agreeing to accept the Assumed Liabilities set forth in Section
1.4. The amount of the Assumption Cost is based on the intention of the parties
that all of the Assumed Leases requiring consent for assignment will be properly
assigned with the Buyer assuming all obligations thereunder. Seller shall use
Commercially Reasonable Efforts to obtain all necessary written consents to
assignment within 60 days after the Closing Date. For each Assumed Lease for
which consent is not obtained, the Assumption Cost shall be reduced accordingly
and as pursuant to the Total Amount Column Exhibit 1. As consents are obtained
post-Closing Date, Buyer shall, at Seller's request, execute the Assignment and
Assumption of Lease in the same or substantially the same form attached hereto
as Exhibit 3.

Further, for any Assumed Lease not requiring consent to assignment, Buyer agrees
to be responsible for lease payments under the Assumed Leases immediately upon
execution of this Agreement and agrees to execute the Assumption and Assignment
of Lease, attached hereto, contemporaneously with this Agreement. For any
Assumed Lease requiring consent, Seller agrees to be responsible for lease
payments until consent to assignment is obtained. Buyer agrees to immediately
execute the Assignment and Assumption of Lease when the consent to assignment is
provided.

On or before the Closing Date, Seller shall provide Buyer with actual or
constructive physical possession of the Subject Assets and the Records, except
as expressly excluded herein. Seller's obligations are specifically contingent
upon Buyer complying with Section 4.2 herein regarding Cooperation and the
parties entering into a mutually acceptable change control process agreement
that prohibits any changes to systems, access or services affecting dial-up and
web-hosting services retained by the Seller during the transfer of the Subject
Assets or until February 28, 2007, whichever period is longer. The agreement
must be entered into within 30 days of the Closing Date, and will be attached as
Exhibit 4 to this Agreement and incorporated herein upon execution.

written consent of Seller, which consent may be withheld by Seller, at Seller's

agreements, and Buyer agrees that it will be responsible for identifying the
individuals or entities with whom the agreements were made; notifying these
individuals or entities of the transfer of ownership of the equipment in
question; entering into any written agreements for future use of property owned
by the individuals or entities; and deciding what "credits" should be issued to

use Commercially Reasonable Efforts to provide to Buyer within 30 days after the
Closing Date all information that it possesses regarding these oral agreements.
These oral agreements shall not constitute Retained Liabilities.
