          (g) All records and files  necessary or  appropriate to own or operate
     the Assets

or perform the obligations explicitly assumed by Buyer.

Any of the assets of Seller not listed above shall be retained by Seller and are
referred to herein as the excluded assets (the "Excluded Assets").

     2. Assignment and Assumption of the  Liabilities.  Subject to the terms and
conditions  contained  in this  Agreement,  on the Closing  Date,  Seller  shall
assign,  transfer,  convey and deliver to Buyer, and Buyer shall assume and pay,
all of Seller's right, title and interest in and to (i) all of Seller's accounts
payable  and certain of Seller's  accrued  liabilities,  each as existing on the
Closing Date,  provided that such  payables and  liabilities  are also listed on
(and only to the extent of the amount reflected on) "Schedule 2.1" hereto,  (ii)
all of  Seller's  purchase  orders  (except  those  that are not  related to the
Operating Business and are cancelable) and contracts with vendors, customers and
distributors  existing on the Closing Date,  provided that such purchase  orders
and  contracts  are  also  listed  on  "Schedule  2.2"  hereto,  and  (iii)  the
compensation  and severance  benefits owed to Seller's  employees,  based on the
data listed on "Schedule 2.3" and the severance  benefits  generally provided to
employees of Seller. The items referred to in clauses (i), (ii), and (iii) above
are collectively referred to as the "Assumed  Liabilities".  On the Closing Date
Buyer shall assume sole  responsibility  to perform,  satisfy and  discharge all
duties,  obligations,  terms, conditions and covenants arising after the Closing
Date that the Seller is  otherwise  bound to  perform,  discharge  or  otherwise
satisfy,  to the extent and only to the extent  such  responsibilities,  duties,
obligations,  terms,  conditions  and covenants are  explicitly  included in the
Assumed  Liabilities.  Except as set forth above,  Buyer shall not assume, or in
any way be liable or responsible for, any of the liabilities,  accounts payable,
orders,  contracts,  agreements,  leases,  or other  obligations  of any  nature
whatsoever of Seller. As to the severance  benefits owed to Seller's  employees,
Buyer  agrees that as to any employee of Seller to whom it either does not offer
employment  initially  following  the Closing or that it  terminates  within six
months following the Closing for any reason other than  non-performance  by such
employee or for cause,  Buyer shall pay severance benefits based on Schedule 2.3
for such employee.

     3. Premises Lease.  Buyer shall not assume any obligations  pursuant to the
lease for the premises  currently  occupied by Seller (the "Premises") but shall
be granted  the right by Seller on the Closing  Date to occupy such  Premises on
the temporary basis described below. At Closing,  Buyer will pay Seller a fee of
$32,670 for the right to access and use the Premises  for thirty days  following
the Closing  Date.  Following  that thirty day period,  Buyer will pay Seller in
advance a fee of  $8,167.50  for the right to access  and use the  Premises  for
successive  seven day  periods.  Buyer may vacate the  Premises  at any time and
cease  payments  upon 30 days'  notice  to  Seller.  Buyer  shall  have no other
obligation  related to the  Premises,  and Seller  agrees to indemnify  and hold
Buyer  harmless  against  any and all claims by any third  party  related to the
Premises;  provided,  however,  Buyer shall not be held harmless from any claims
caused by the acts or negligence of Buyer or its employees or agents.

     4.  Purchase  Price.  In  consideration  of Seller's  sale of the Assets to
Buyer,  Buyer  unconditionally  agrees, in addition to assumption of the Assumed
Liabilities,  to pay to Seller at Closing a total of $1,000  (hereinafter called
the "Purchase Price").

                                       2

     5. Contingent Payments.

          (a) In addition  to the  Purchase  Price to be paid at  Closing,  upon
     satisfaction of the conditions set forth in this Section 5, Buyer will make
     payments  ("Contingent  Payments")  to Seller  based  upon 10% of the gross
     receipts  as  accrued  by Buyer that  exceed  $7,500,000  during an Earnout
     Period (the  "Annual  Threshold")  as a result of the sale of products  and
     services that use or are based,  in whole or in part,  on the  intellectual
     property  transferred  by  Seller to Buyer  (the  "Ongoing  Business").  An
     "Earnout  Period" is a  12-month  period.  The first  Earnout  Period  will
     commence on the first day of the calendar month following the Closing Date.
     The Contingent  Payment may be payable for up to five Earnout Periods.  The
     maximum amount of Contingent Payment payable by Buyer to Seller, during all
     Earnout Periods together, is $2,200,000.

          (b)  Subject  to the credit  described  in the last  sentence  of this
     Section 5(b) and the aggregate  maximum  amount  described in Section 5(a),
     the Contingent Payments following the Closing Date, will be made in cash on
     a quarterly  basis during the first three  quarters of each Earnout  Period
     using  $1,875,000 as the quarterly  threshold  gross  revenue  target.  The
     amount of the final quarterly  payment will be determined  using the Annual
     Threshold and the actual annual gross  revenues  during such Earnout Period
     and will subtract any quarterly payments  previously made for such year. If
     at the end of each Earnout Period (other than the first Earnout  Period) it
     is  determined  that the sum of the  quarterly  payments  for such  Earnout
     Period  exceeds the actual  payment due as  determined  on an annual  basis
     ("Excess  Payments"),  such Excess  Payments may be retained by the Seller,
     but will be credited against amounts due in future Earnout Periods.

          (c) The  Contingent  Payment,  if any,  due to  Seller  for the  first
     quarterly  period of the first Earnout Period shall be paid to Seller.  The
     first  $200,000  of  Contingent  Payments  due to Seller for the second and
     subsequent  quarterly periods (the "Holdback Amount") will be held by Buyer
     in a  segregated  interest  bearing  account  and  may  be  unconditionally
     released,  upon five (5) days advanced written notice to Seller  describing
     such  liabilities,  to compensate  Buyer for any  liabilities  of Seller to
     Buyer under this Agreement and to compensate  Buyer for any Excess Payments
     made during the first Earnout Period.  The amount,  if any, of the Holdback
     Amount  remaining at the end of the ninth  earnout  quarter will be paid to
     Seller on such date.

          (d) In the event the net working capital as of the Closing Date of the
     Ongoing Business is less than $(658,000) (the "Target Number"),  then Buyer
     shall be  entitled  to offset  the  amount of the  difference  against  any
     Contingent  Payments  payable in  accordance  with this  Section 5, thereby
     reducing  the  Contingent  Payments  payable  and  the  maximum  amount  of
     Contingent Payments payable by the difference. In the event the net working
     capital as of the Closing Date is more than the Target Number,  then Seller
     shall be entitled to an increase in the amount of the  Contingent  Payments
     payable  at the end of the first  Earnout  Period in  accordance  with this
     Section  5 equal to the  amount in excess  of the  Target  Number,  thereby
     increasing  the  maximum  amount  of  Contingent  Payments  payable  by the
     difference. Net working capital shall be the sum of

                                       3

     accounts   receivable  and  inventory  minus  accounts   payable,   accrued
     liabilities, and unearned revenue.

          (e) Any amounts paid by Buyer to Seller  hereunder shall be used first
     to satisfy any claims for payment made by any third party against Seller.

     6.  Closing.  The  closing  ("Closing")  shall take place at the offices of
Blackwell  Sanders  LLP in Kansas  City,  Missouri  on  September  14, 2007 (the
"Closing  Date").  The Closing shall be effective as of 12:01 a.m. local time on
the Closing Date.

     any of the  representations  and warranties of Seller contained herein from
     being true in all material  respects at and as of the Closing Date with the
     same effect as though such  representations and warranties had been made at
     and as of the Closing Date.

     11. Indemnification and Resolution of Disputes.

          (A) Seller's  Indemnification.  Seller agrees to defend, indemnify and
hold harmless  Buyer  against and in respect of any and all loss,  liability and
expense resulting from:

               (1)  The inaccuracy of any  representation  or breach of warranty
                    or  non-fulfillment  of any  obligation by Seller under this
                    Agreement;

               (2)  Any  liabilities,  accounts  payable  or  other  obligations
                    relating  to the Assets or the Ongoing  Business  other than
                    the Assumed Liabilities; and

               (3)  Any and all actions,  suits,  proceedings,  claims, demands,
                    assessments, tax deficiencies, judgments, costs and expenses
                    (including attorneys' fees) incident to any of the foregoing
                    provisions.

               (B) Claims  Procedure.  Promptly after the assertion of any claim
by Buyer with respect to any matter  referred to in paragraph (A) above,  or the
receipt by Buyer of written notice of the assertion or the  commencement  of any
litigation with respect to any matter referred to in paragraph (A) above,  Buyer
shall give  written  notice of such claim to Seller  and  thereafter  shall keep
Seller reasonably informed with respect to that claim;  provided,  however, that
failure of Buyer to give notice as provided  in this  section  shall not relieve
Seller of its obligations  hereunder unless such failure prejudices or adversely
effects  Seller's  obligations  hereunder.  If any litigation is brought against
Buyer,  Seller shall be entitled to participate in such  litigation,

                                       8

and at the request of Buyer,  shall  assume the  defense  thereof  with  counsel
satisfactory  to the Buyer at the Seller's sole expense.  If Seller  assumes the
defense  of any  litigation,  it shall not  settle  the  litigation  unless  the
settlement shall include,  as an unconditional  term thereof,  the giving by the
claimant or plaintiff  of a release of Buyer,  satisfactory  to Buyer,  from all
liability with respect to such litigation.

               (C) Buyer's  Indemnification.  Buyer agrees to defend,  indemnify
and hold harmless  Seller against and in respect of any and all loss,  liability
and expense resulting from (i) the inaccuracy of any representation or breach of
warranty or non-fulfillment of any obligation by Buyer under this Agreement, and
(ii) any act or  negligence  of  Buyer,  its  officers,  employees,  and  agents
occurring  subsequent to the Closing and directly  related to its conduct of the
operations of the Ongoing Business.

               (D) Claims  Procedure.  Promptly after  assertion of any claim by
Seller with  respect to any matter  referred to in paragraph  (C) above,  or the
receipt by Seller of written notice of the assertion or the  commencement of any
litigation with respect to any matter referred to in paragraph (C) above, Seller
shall give written notice of such claim to Buyer and thereafter shall keep Buyer
reasonably informed with respect to that claim; provided,  however, that failure
of Seller to give notice as provided in this section  shall not relieve Buyer of
its obligations  hereunder unless such failure  prejudices or adversely  effects
Buyer's  obligations  hereunder.  If any litigation is brought  against  Seller,
Buyer shall be entitled to participate in such litigation, and at the request of
Seller, shall assume the defense thereof with counsel satisfactory to the Seller
at the Buyer' sole expense.  If Buyer assumes the defense of any litigation,  it
shall not settle the  litigation  unless the  settlement  shall  include,  as an
unconditional term thereof, the giving by the claimant or plaintiff of a release
of Seller,  satisfactory  to Seller,  from all  liability  with  respect to such
litigation.

     12.  Expenses.  Each  party to this  Agreement  shall pay its own  expenses
incidental to the  negotiation,  preparation,  execution and performance of this
Agreement and the transaction  contemplated hereby,  including,  but not limited
to,  the fees and  expenses  of their  respective  legal  counsel,  brokers  and
accountants.  Seller  shall  pay any  sales,  use or  transfer  taxes or fees in
connection with the transaction contemplated hereby.

     13.  Covenant Not to Compete.  From and after the Closing Date for a period
of  five  (5)  years,  Seller  shall  not,  and  shall  not  permit  any  of its
stockholders,  officers,  or directors to, compete with Buyer in any business of
the type  carried on by Seller  prior to the  Closing  Date in any area in which
Buyer is engaged in business. The term "compete" as used herein, means to engage
in competition,  directly or indirectly,  (including,  without  limitation:  (i)
soliciting  or selling to any  customer  with which  Buyer has or Seller had any
direct or indirect business contacts; (ii) developing,  marketing, licensing, or
distributing  any product or service related to the Ongoing  Business;  or (iii)
seek to hire or hire any employee of Buyer or any of its  affiliated  entities),
either as a proprietor, partner, employee, agent, consultant,  stockholder or in
any capacity or manner whatsoever.  The parties hereby acknowledge that remedies
at law for violations of this paragraph are inadequate and that only  injunctive
relief  is an  adequate  remedy  for such  violations.  The  provisions  of this
paragraph  are  severable;  if any  provision of this  paragraph or  application
thereof to any  circumstance is held invalid,  such invalidity  shall not

                                       9

affect the  provisions  or  applications  of this  paragraph  which can be given
effect without the invalid provision or application.

constitutes the entire agreement  between the parties  pertaining to the subject
matter contained herein,  and supersedes all prior  agreements,  representations
and  understandings  of the parties.  No  modification  shall be binding  unless
executed in writing by the parties. No waiver of any provisions shall be deemed,
or shall constitute, a waiver of any other provision whether or not similar, nor
shall any waiver at one time constitute a continuing  waiver. No waiver shall be
binding unless executed in writing by the party making such waiver.

     15. Binding  Effect.  This  Agreement  shall be binding on and inure to the
benefit of the parties  hereto,  their  shareholders,  successors  in  interest,
heirs, executors and assigns.

     16.  Execution in  Counterparts;  Binding  Effect.  This  Agreement  may be
executed via facsimile and in one or more  counterparts,  each of which shall be
deemed an original and all of which  together  shall be  considered  one and the
same  agreement,  and  shall  become  a  binding  agreement  when  one  or  more
counterparts have been signed by each party and delivered to the other party.

     17.  Governing Law. This Agreement  shall be considered in accordance  with
and be governed by the laws of the State of Kansas.

     18.  Survival.  The provisions of this Agreement  shall survive the Closing
Date in accordance with the following provisions:

          (A) The  warranties  and  representations  made by each  party in this
Agreement shall survive for a period of thirty-six (36) months.
