      2.7 ADDITIONAL  MERGER  CONSIDERATION  . In addition to the Initial Merger
Consideration,   each  Shareholder   shall  be  entitled  to  additional  merger
consideration (the "Additional Merger Consideration") calculated as follows:

            (a) 2006 Revenue Adjustments to Merger Consideration.

                  (i) Calculation of Additional Merger Consideration  (2006). In
the event that the 2006 Company  Revenue  exceeds the 2005 Company Revenue (such
excess, if any, the "2006 Incremental Company Revenue"),  Parent shall issue, as
additional  Stock  Consideration,  shares of Parent  Common  Stock  derived from
calculating through that certain formula set forth in Exhibit B attached hereto.
The 2005  Company  Revenue  and 2006  Company  Revenue  shall be  calculated  by
management of Parent in good faith and such  calculations  shall be delivered to
the  Shareholders.  The  Shareholders  shall have ten (10) days from the date of
receipt of such calculations to dispute the calculations.  If one or more of the
Shareholders  dispute such  calculations  during such  period,  the parties will
resolve such dispute in accordance with the dispute provisions of Article 10. If
neither   Shareholder   disputes  such  calculation   during  such  period,  the
calculations of Parent shall be final and binding on all parties. The additional
Stock Consideration payable pursuant to this Section 2.7(a)(i), if any, shall be
made in  accordance  with each  Shareholder's  respective  pro rata share of the
Stock   Consideration   paid  on  the  Closing  Date.   The   additional   Stock
Consideration,  if any,  issuable and payable pursuant to this Section 2.7(a)(i)
shall be referred to as the "2006 Incremental Revenue Payment."

                  (ii)  Incremental  Revenue Payment Date.  Parent shall pay the
2006 Incremental  Revenue Payment, if any, on or before June 30, 2006 unless the
Shareholders  dispute  Parent's  calculations of the 2006 Company Revenue or the
2005  Company  Revenue,  as the case may be, in which case Parent  shall pay the
applicable 2006  Incremental  Revenue  Payment,  if any, within thirty (30) days
after  resolution  of the dispute in accordance  with the dispute  provisions of
Article 10.

                  (iii) Incremental  Revenue Deficit. In the event that the 2005
Company Revenue exceeds the 2006 Company Revenue (a "2006 Revenue Decline"),  no
Additional Merger Consideration pursuant to this Section 2.7(a) shall be paid.

            (b) 2007 Revenue Adjustments to Merger Consideration.

                  (i)  Calculation of Additional  Merger  Consideration  (2007).
Subject to the provisions of Section  2.7(b)(iii),  below, in the event that the
2007 Company Revenue exceeds the 2006 Company Revenue (such excess,  if any, the
"2007  Incremental  Company  Revenue"),  Parent shall issue, as additional Stock
Consideration,  shares of Parent Common Stock derived from  calculating  through
that certain  formula set forth in Exhibit B attached  hereto.  The 2006 Company
Revenue and 2007 Company  Revenue shall be calculated by management of Parent in
good faith and such  calculations  shall be delivered to the  Shareholders.  The
Shareholders  shall  have  ten  (10)  days  from  the  date of  receipt  of such
calculations  to dispute the  calculations.  If one or more of the  Shareholders
dispute  such  calculations  during such  period,  the parties will resolve such
dispute in  accordance  with the  dispute  provisions  of Article 10. If neither
Shareholder  disputes such calculation  during such period,  the calculations of
Parent  shall  be  final  and  binding  on all  parties.  The  additional  Stock
Consideration payable pursuant to this Section 2.7(b)(i),  if any, shall be made
in accordance  with each  Shareholder's  respective  pro rata share of the Stock
Consideration paid on the Closing Date. The additional Stock  Consideration,  if
any, issuable and payable pursuant to this Section 2.7(b)(i) shall be referred


                                      -11-

                                                                   Exhibit 10.31

to as the "2007 Incremental Revenue Payment."

                  (ii)  Incremental  Revenue Payment Date.  Parent shall pay the
2007 Incremental  Revenue Payment, if any, on or before June 30, 2007 unless the
Shareholders  dispute  Parent's  calculations of the 2007 Company Revenue or the
2006  Company  Revenue,  as the case may be, in which case Parent  shall pay the
applicable 2007  Incremental  Revenue  Payment,  if any, within thirty (30) days
after  resolution  of the dispute in accordance  with the dispute  provisions of
Article 10.

                  (iii) Notwithstanding the provisions of Section 2.7(b)(i),  in
the event there shall have been a 2006 Revenue Decline,  the calculation for the
2007 Incremental  Revenue Payment, if any, shall be based on the increase in the
2007 Company Revenues over the 2005 Company  Revenue,  if any, such excess being
the basis for the 2007 Incremental Company Revenue calculations.

                  (iv) Incremental  Revenue Deficit.  In the event that the 2006
Company  Revenue  exceeds  the  2007  Company  Revenue,   no  Additional  Merger
Consideration pursuant to this Section 2.7(b) shall be paid.

entitled  to receive  in  exchange  therefor  the Cash  Consideration  and Stock
Consideration to which such holder of Company Common Stock is entitled  pursuant
to Section 2.6 above and the Additional Merger  Consideration,  if any, pursuant

Company Common Stock represented by such Stock Certificate have been converted.

registration  of  transfers  on  the  stock  transfer  books  of  the  Surviving
Corporation of Company Common Stock which were outstanding  immediately prior to
the  Effective  Time.  If, after the  Effective  Time,  Stock  Certificates  are
presented to the Surviving  Corporation  for any reason,  they shall be canceled
and  exchanged  as provided in this Section 2.8,  provided  that the  presenting
holder is listed on the Company's Shareholder list as a holder of Company Common
Stock.

            (c) In the event  that any  Stock  Certificates  evidencing  Company
Common Stock shall have been lost, stolen or destroyed,  the Parent shall pay in
exchange for such lost, stolen or destroyed Stock Certificates,  upon the making
of an affidavit of that fact by the holder thereof, such Merger Consideration as
may be required pursuant to Sections 2.6 and 2.7 above; provided,  however, that
Parent  may, in its  discretion  and as a condition  precedent  to the  issuance
thereof,  require the owner of such lost, stolen or destroyed Stock Certificates
to deliver a bond in such sum as it may reasonably  direct as indemnity  against
any claim that may be made against Parent with respect to the Stock Certificates
alleged to have been lost, stolen or destroyed.

            (d)  Notwithstanding  anything to the  contrary in this Section 2.8,
none of the  Surviving  Corporation  or any  party  hereto  shall be liable to a

under the Securities Act. Notwithstanding the provisions of clauses (i) and (ii)
above, no such  registration  statement or opinion of counsel shall be necessary
for a transfer by such  Shareholder  to a family member of such  Shareholder  or
trust for the benefit of such Shareholder or family member;  provided,  however,
that in each case the  transferee  will be  subject to the terms of Article 5 of


                                      -36-

this  Agreement  to the  same  extent  as if  he,  she or it  were  an  original
Shareholder  hereunder.  Parent  shall  be  entitled  to  impose  stop  transfer
instructions  with  respect to the Parent  Common  Stock in order to enforce the
foregoing restrictions.

      The  certificates  representing  the  Parent  Common  Stock  (when  issued
pursuant  to  this  Agreement)  shall  bear  the  following  legend  restricting
transfer,  and such other  legends as may be  required by any  applicable  state
securities law:

                  THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER
                  THE  SECURITIES  ACT OF 1933, AS AMENDED.  THEY
                  MAY NOT BE SOLD,  OFFERED FOR SALE,  PLEDGED OR

                  STATEMENT   IN  EFFECT  WITH   RESPECT  TO  THE
                  SECURITIES  UNDER  SUCH  ACT OR AN  OPINION  OF
                  COUNSEL  SATISFACTORY  TO THE COMPANY THAT SUCH
                  REGISTRATION  IS NOT  REQUIRED  OR UNLESS  SOLD
                  PURSUANT TO RULE 144 OF SUCH ACT.

                  HOLDING, INC.

      5.4 MARKET STANDOFF.  Such Shareholder agrees that he, she or it will not,
without the prior written consent of Parent and/or the managing  underwriter(s),
during the period  commencing on the date of filing of a registration  statement
by Parent pursuant to an  underwritten  public offering by Parent of its capital
stock or  securities  convertible  into its capital stock and ending on the date
specified by Parent and the managing  underwriter(s)  (such period not to exceed
180  days  following  the  filing  of the  final  prospectus  relating  to  such
offering),  transfer  or dispose of any shares of Parent  Common  Stock owned by
such Shareholder.  In order to enforce the foregoing covenant, Parent may impose
stop-transfer  instructions  with respect to such  securities of the Shareholder
(and the shares or  securities  of every other Person  subject to the  foregoing
restriction) until the end of such period.

      9.2 INDEMNIFICATION.

            (a) By the  Company  and  the  Shareholders.  The  Company  and  the
Shareholders shall severally indemnify,  defend and hold harmless Parent and the
Surviving  Corporation  and their  respective  officers,  directors,  employees,
Affiliates,  agents,  successors,  subsidiaries  and assigns  (collectively  the
"Parent Group") from and against any and all costs,  losses (including,  without
limitation,  diminution in value), liabilities, damages, lawsuits, deficiencies,
claims and expenses, including without limitation, interest, penalties, costs of
mitigation,  attorneys' fees and all amounts paid in  investigation,  defense or
settlement of any of the foregoing  (collectively,  the "Damages"),  incurred in
connection with, arising out of, resulting from or incident to (i) any breach of
any  covenant,  representation,  warranty or agreement or the  inaccuracy of any
representation  made by the Company or the  Shareholders  in or pursuant to this
Agreement,   or  in  the  other  documents  delivered  in  connection  with  the
Contemplated  Transactions pursuant to Section 2.10, (ii) Actions or Proceedings
set forth in the Company Disclosure Schedule or in the other documents delivered
in connection with the Contemplated  Transactions,  (iii) Actions or Proceedings
involving the Company whether  disclosed in the Company  Disclosure  Schedule or
not, (iv)  operations of the Business of the Company through March 20, 2005, (v)
the  transactions  contemplated by Section 2.9 or as a result of a breach of any
of the covenants or understandings contained in Section 2.9, and (vi) any Income
Tax  liability  of the  Shareholders  or the  Company  arising or accruing on or
before the Closing Date.

            (b) By  Parent.  Parent  and  Acquisition  Co.  shall,  jointly  and
severally,  indemnify,  defend and hold  harmless,  the  Shareholders  and their
respective  heirs,  successors  and assigns from and against any and all Damages
incurred in connection  with,  arising out of, resulting from or incident to any
breach of any covenant, representation,  warranty or agreement or the inaccuracy
of any  representation  made by Parent or Acquisition Co. in or pursuant to this
Agreement,  or in the documents  delivered in connection  with the  Contemplated
Transactions pursuant to Section 2.10.

            (c)  Third  Party  Claims;  Defense  of  Claims.  If any  Action  or
Proceeding  is filed or initiated  against any party  entitled to the benefit of
indemnity  hereunder,  written notice thereof shall be given to the indemnifying
party as promptly  as  practicable  (and in any event  within ten days after the
service of the citation or summons);  provided, however, that the failure of any
indemnified   party  to  give  timely   notice   shall  not  affect   rights  to
indemnification  hereunder  except to the  extent  that the  indemnifying  party
demonstrates  actual damage caused by such  failure.  After such notice,  if the
indemnifying  party shall  acknowledge in writing to the indemnified  party that
the  indemnifying  party  shall be  obligated  under the terms of its  indemnity
hereunder in connection  with such Action or Proceeding,  then the  indemnifying
party shall be  entitled,  if it so elects,  to take  control of the defense and
investigation of such Action or Proceeding and to employ and engage attorneys of
its own choice to handle and defend the same,  such  attorneys to be  reasonably
satisfactory to the indemnified  party, at the  indemnifying  party's cost, risk
and expense (unless (i) the indemnifying  party has failed to assume the defense
of such  Action  or  Proceeding  or (ii) the  named  parties  to such  Action or
Proceeding include both of the indemnifying party and the indemnified party, and
the indemnified  party and its counsel determine in good faith that there may be
one or  more  legal  defenses  available  to such  indemnified  party  that  are
different from or additional to those  available to the  indemnifying  party and
that joint representation  would be inappropriate),  and to compromise or settle
such Action or Proceeding,  which compromise or settlement shall not require the


                                      -41-

                                                                   Exhibit 10.31

consent of the  indemnified  party if such  compromise or settlement  includes a
full  and  unconditional  release  of  the  indemnified  party,  otherwise  such
compromise  or  settlement  shall be made only with the  written  consent of the
indemnified party, such consent not to be unreasonably withheld. The indemnified
party may withhold such consent if such compromise or settlement would adversely
affect the conduct of business or requires less than an unconditional release to
be obtained.  If (i) the indemnifying  party fails to assume the defense of such
Action or  Proceeding  within  ten (10) days  after  receipt  of notice  thereof
pursuant  to this  Section  9.2,  or (ii) the named  parties  to such  Action or
Proceeding include both the indemnifying party and the indemnified party and the
indemnified  party and its counsel determine in good faith that there may be one
or more legal defenses  available to such  indemnified  party that are different
from or additional to those available to the  indemnifying  party and that joint
representation would be inappropriate,  the indemnified party against which such
Action or Proceeding has been filed or initiated will (upon delivering notice to
such  effect to the  indemnifying  party)  have the right to  undertake,  at the
indemnifying party's cost and expense, the defense,  compromise or settlement of
such  Action or  Proceeding  on behalf  of and for the  account  and risk of the
indemnifying  party. In the event the  indemnified  party assumes defense of the
Action or Proceeding,  the indemnified  party will keep the  indemnifying  party
reasonably  informed  of  the  progress  of  any  such  defense,  compromise  or
settlement and will consult with, when appropriate,  and consider any reasonable
advice  from,  the  indemnifying  party  of  any  such  defense,  compromise  or
settlement.  The  indemnifying  party shall be liable for any  settlement of any
action effected  pursuant to and in accordance with this Section 9.2 and for any
final  judgment  (subject to any right of appeal),  and the  indemnifying  party
agrees to indemnify and hold harmless the indemnified party from and against any
Damages by reason of such settlement or judgment.


      Regardless  of whether the  indemnifying  party or the  indemnified  party
takes up the  defense,  the  indemnifying  party will pay  reasonable  costs and
expenses in connection with the defense, compromise or settlement for any Action
or Proceeding under this Section 9.2.


      The indemnified party shall cooperate in all reasonable  respects with the
indemnifying party and such attorneys in the investigation, trial and defense of
such Action or Proceeding and any appeal arising therefrom;  provided,  however,
that  the  indemnified   party  may,  at  its  own  cost,   participate  in  the
investigation,  trial and  defense of such Action or  Proceeding  and any appeal
arising therefrom.  The indemnifying party shall pay all expenses due under this
Section 9.2 as such expenses become due.

            (d) Indemnity Claims. A claim for indemnification for any matter not
involving a  third-party  claim may be asserted by notice to the party from whom
indemnification is sought.

      9.3 RIGHT OF OFFSET.

            (a) In the event that Parent or the  Surviving  Corporation  suffers
Damages  pursuant  to this  Article  9, the  Parent,  in  addition  to all other
remedies  set forth in this  Section  9.3,  shall have the right to offset  such
Damages  against  amounts  payable  to the  Shareholders  as  Additional  Merger
Transaction pursuant to Section 2.7, if any.


                                      -42-

                                                                   Exhibit 10.31

            (b) Neither  party shall have any  liability  or  obligation  to the
other party with respect to any claim related to this Agreement  until the total
of all Damages with respect to such matters  exceed  $25,000 (the  "Threshold"),
and  thereafter,  liability  shall be only for  those  Damages  in excess of the
Threshold.

            (c) Neither  party shall have any  liability  or  obligation  to the
other person in connection with any claim related to this Agreement in excess of
the Merger  Consideration.

            (d) The  determination  of the amount of any Damages  arising out of
the breach of more than one  representation,  warranty,  covenant  or  agreement
shall be determined without duplication or double counting of the same Damages.

            (e) Any amounts  payable by either party  pursuant to this Article 9
shall be reduced by (i) any related  insurance  recoveries  net of cost incurred
for  such  recovery  and  (ii)  any  payments  from  third  parties  who are not
Affiliates.

            (f) Each party shall use reasonable  efforts to minimize any Damages
for which any other party may be liable pursuant to this Agreement.

      9.4 ARTICLES OF INCORPORATION AND BYLAWS.  Notwithstanding anything to the
contrary in the Articles of  Incorporation  or Bylaws or governing  documents of
the Company or HIP, LLC, the indemnification  provisions of this Article 9 shall
take  precedence  over such  Articles  of  Incorporation,  Bylaws,  Articles  of
Organization,  operating agreement or other governing documents.  No Shareholder
or any other  officer or director of the Company  prior to the Closing  shall be
entitled  to  indemnification  directly  or  indirectly  under such  Articles of
Incorporation,  Bylaws,  Articles of Organization,  operating agreement or other
governing  documents or otherwise  for any matter upon which the Company or HIP,
LLC has or might have an indemnification  obligation  hereunder and the Articles
of  Incorporation,  Bylaws,  Articles of Organization,  operating  agreement and
governing documents shall be deemed amended accordingly. This Section 9.4 is not
intended for the benefit of creditors or other third  parties and does not grant
any rights to creditors or other third parties.

      9.5  EXCLUSIVITY.  The  parties  hereto  acknowledge  and  agree  that the
indemnity  obligations  set forth  above  shall be the  exclusive  remedy of the
indemnified parties with respect to any claim or causes of action that may arise
or relate to this Agreement or the Contemplated Transactions.

      9.6 TAX MATTERS.

            (a) Filing Returns and Paying Taxes.

                  (i)  The  Shareholders   shall,  at  their  sole  expense,  be
responsible  for preparing and timely filing (which the  Shareholders  do hereby
jointly  and  severally  agree to timely  prepare  and file) (A) all  Income Tax
Returns of the  Company and HIP,  LLC for Tax periods  that end on or before the
Closing  Date  (regardless  of their due date)  and (B) all Tax  Returns  of the
Company  and  HIP,  LLC  that  are  due  on or  before  the  Closing  Date.  The
Shareholders  agree to promptly provide Parent true and exact copies of all such
Tax Returns.  Subject to Section 2.9 and Section 3.26, the Shareholders shall be


                                      -43-

                                                                   Exhibit 10.31

responsible for paying all Taxes due on such returns.

                  (ii)  Except  for  the  Income  Tax   Returns   filed  by  the
Shareholders  pursuant to Section 9.6(a)(i),  Parent will be responsible for the
preparation  and timely  filing of all Tax Returns of the  Company and HIP,  LLC
that are due after the Closing  Date  (including  Tax  Returns for periods  that
begin  before  but end after the  Closing  Date).  Subject to  Sections  2.9 and
Section 3.26,  Parent will be  responsible  for paying all Taxes due on such Tax
Returns.

                  (iii) Except where required under applicable law or compulsory
legal process,  neither Parent,  Acquisition Co., the Company, HIP, LLC, nor the
Shareholders  will  take a  position  with any  federal,  state or local  taxing
authority contrary to any of the terms and provisions of this Agreement.

                  (iv)  Unless the  Shareholders  consent in writing  and except

limitations)  of  the  respective  taxable  periods,  and  (B)  to  provide  the
Shareholders a reasonable  opportunity to copy (at the Shareholders'  sole cost)
any such records  (unless  prohibited  by  applicable  law or  compulsory  legal

records.

                  (ii) With  respect to income Tax  Returns of the  Company  and

have the  right  (at the  Shareholders'  sole  cost)  to  control  any  audit or
examination  by any Tax  authority,  initiate  any  claim for  refund,  file any

liable after the Closing;  except where any of the foregoing is likely to have a
Material  Adverse Effect on the Parent,  the Company the Acquisition Co, or HIP,

                                   ARBITRATION
                                   -----------

      10.1 ARBITRATION.  In the event of any dispute among the parties hereto as
to the  interpretation  of any  provision  of this  Agreement  or the rights and
obligations  of any party  hereunder,  such dispute  shall be resolved (i) first
through  negotiations in good faith between the parties to such dispute and (ii)
if during a fifteen (15) day period following the date such dispute arises, such
negotiations  do not  result in a  resolution  through  binding  arbitration  as
hereinafter provided. If arbitration is required to resolve a dispute hereunder,
any party may notify  the  American  Arbitration  Association  in Dallas,  Texas
("AAA")  and  request  AAA to select  one  person to act as the  arbitrator  for
resolution of the dispute.  The  arbitrator  so selected  shall conduct any such
proceedings using the International Arbitration Rules (the "IAR") of the AAA and
such rules will be binding upon all parties to the arbitration  proceeding.  The
arbitrator is encouraged to modify the  application of the IAR as the arbitrator
deems  appropriate  to  accomplish  the  arbitration  in the  quickest and least
expensive manner possible. Accordingly, the arbitrator may (i) dispense with any
formal rules of evidence and allow  hearsay  testimony so as to limit the number
of witnesses  required,  (ii) accept  evidence of property values without formal
appraisals  and upon such  information  provided by the parties or other persons
and otherwise minimize discovery procedures as the arbitrator deems appropriate,
(iii)  act upon his  understanding  or  interpretation  of the law on any  issue
without the  obligation  to research  such issue or accept or act upon briefs of
the issue  prepared by any party,  (iv) limit the time for  presentation  of any
party's case as well as the amount of  information  or number of witnesses to be
presented in connection  with any hearing,  and (v) impose any other rules which
the  arbitrator  believes  appropriate  to effect a resolution of the dispute as
quickly and  inexpensively  as possible.  The arbitrator will have the exclusive
authority to determine and award costs of arbitration  and the costs incurred by
any party for their attorneys, advisors and consultants.

                                  MISCELLANEOUS
                                  -------------

      11.1 FURTHER ASSURANCES. In case at any time after the Closing any further
action is necessary  or  desirable to carry out the purposes of this  Agreement,
each of the parties will take such further  action  (including the execution and
delivery  of  such  further  instruments  and  documents)  as  the  other  party
reasonably may request, all at the sole cost and expense of the requesting party
(unless  the  requesting  party is entitled to  indemnification  therefor  under
Article IX).
