REPRESENTATIONS AND WARRANTIES OF AVTX

AVTX, the Principal Shareholders and, where applicable, the Merger Sub

the ordinary course of business or as otherwise provided in any contracts or

agreements with any such employees;

(c) shall not merge or consolidate with any other entity or acquire or

agree to acquire any other entity;

<PAGE>

(d) shall not sell, transfer, or otherwise dispose of any material

assets required for the operations of SXAN’s business, except in the ordinary

course of business consistent with past practices;

(e) shall not declare or pay any dividends on or make any distribution

of any kind with respect to the SXAN Shares; and

(f) shall use commercially reasonable efforts to comply with and not be

in default or violation under any known law, regulation, decree or order

applicable to SXAN’s business, operations or assets where such violation would

have a Material Adverse Effect on SXAN.

AVTX covenants and agrees that, during the period from the date of this

Agreement until the Closing Date, AVTX shall not, other than as contemplated by

this Agreement or for the purposes of effecting the Closing pursuant to this

Agreement, conduct its business as presently operated and solely in the ordinary

course, and consistent with such operation, and, in connection therewith,

without the written consent of SXAN:

(a) shall not amend its Articles of Incorporation or Bylaws, except to

create the Series B Preferred Shares, as provided in Section 1.02 (a);

compensation of any kind or amount;

any action affecting the capitalization of AVTX or the AVTX Common or Preferred

Shares; and

(h) shall not grant any severance or termination pay to any director,

officer or any other employees of AVTX.

(a) TAX-FREE REORGANIZATION. The Parties intend that the Merger qualify

as a Tax-free “reorganization” under Sections 368(a) of the Code, as amended,

and the Parties will take the position for all purposes that the Merger shall

qualify as a reorganization under such Section. In addition, the Parties

covenant and agree that they will not engage in any action, or fail to take any

<PAGE>

action, which action or failure to take action would reasonably be expected to

cause the Merger to fail to qualify as a Tax-free “reorganization” under Section

Agreement.;

(b) ANNOUNCEMENT. Neither SXAN, on the one hand, nor AVTX on the other

withheld), except as may be required by applicable law or securities regulation.

Upon execution of this Agreement, AVTX shall issue a press release, which shall

be approved by SXAN, and file a Current Report on Form 8-K reporting the

execution of the Agreement.

(c) NOTIFICATION OF CERTAIN MATTERS. SXAN shall give prompt written

notice to AVTX, and AVTX shall give prompt written notice to SXAN, of:

(i) The occurrence or nonoccurrence of any event the

occurrence or nonoccurrence of which would be reasonably likely to cause any

representation or warranty contained in this Agreement to be untrue or

inaccurate in any material respect at or prior to the Effective Time; and

(ii) Any material failure of SXAN or any of the Investors on

the one hand, or AVTX, on the other hand, to comply with or satisfy any

covenant, condition or agreement to be complied with or satisfied by it

hereunder.

(d) REASONABLE BEST EFFORTS. Before Closing, upon the terms and subject

to the conditions of this Agreement, the Parties agree to use their respective

reasonable best efforts to take, or cause to be taken, all actions, and to do,

or cause to be done, all things necessary, proper or advisable (subject to

applicable laws) to consummate and make effective the Share Purchase and the

Merger and other transactions contemplated by this Agreement as promptly as

practicable including, but not limited to:

(i) The preparation and filing of all forms, registrations and

notices required to be filed to consummate the Share Purchase and the Merger,

including without limitation, any approvals, consents, orders, exemptions or

waivers by any third party or governmental entity; and

(ii) The satisfaction of the Party’s conditions precedent to

Closing.

(i) INSPECTION BY SXAN. AVTX will make available for

inspection by SXAN, during normal business hours and in a manner so as not to

interfere with normal business operations, all of AVTX’s and the Operating Sub’s

records (including tax records), books of account, premises, contracts and all

other documents in AVTX’s or the Operating Sub’s possession or control that are

reasonably requested by SXAN to inspect and examine the business and affairs of

AVTX and the Operating Sub. AVTX will cause its managerial employees and regular

independent accountants to be available upon reasonable advance notice to answer

questions of SXAN concerning the business and affairs of AVTX and the Operating

Sub. SXAN will treat and hold as confidential any information it receives from

AVTX in the course of the reviews contemplated by this Section 4.03(e). No

examination by SXAN will, however, constitute a waiver or relinquishment by SXAN

of its rights to rely on AVTX’s covenants, representations and warranties made

herein or pursuant hereto.

(ii) INSPECTION BY AVTX. SXAN will, if requested, make

available for inspection by AVTX, during normal business hours and in a manner

so as not to interfere with normal business operations, all of SXAN’s and TXFF’s

records (including tax records), books of account, premises, contracts and all

<PAGE>

other documents in SXAN’s possession or control that are reasonably requested by

AVTX to inspect and examine the business and affairs of SXAN or TXFF. SXAN will

cause its managerial employees and regular independent accountants to be

available upon reasonable advance notice to answer questions of AVTX concerning

the business and affairs of SXAN and TXFF. AVTX will treat and hold as

confidential any information it receives from SXAN in the course of the reviews

contemplated by this Section 4.03(e). No examination by AVTX will, however,

constitute a waiver or relinquishment by AVTX of its rights to rely on SXAN’s

covenants, representations and warranties made herein or pursuant hereto.

(f) PROTECTION AGAINST DILUTION. AVTX and SXAN jointly, for the benefit

of the Principal Shareholders, covenant that at no time prior to the first

anniversary of the Closing will AVTX issue any equity securities without the

written consent of ▇▇▇▇ ▇▇▇▇, unless the securities are issued in consideration

of a payment of cash to AVTX in an amount determined by the Board of Directors

to be the fair value of the securities.

SXAN Indemnified Party wishing to claim indemnification under this Section 8.01,

upon learning of any such claim, action, suit, proceeding or investigation,

true and correct at or before the Closing, or (ii) any willful or negligent act,

omission or conduct of any officer, director or agent of SXAN or any subsidiary

at or after, the Closing. Any AVTX Indemnified Party wishing to claim

indemnification under this Section 8.02, upon learning of any such claim,

action, suit, proceeding or investigation, shall notify SXAN in writing, but the
