and  information  upon which Buyer's  belief is based.  Buyer shall be deemed to
have  waived,  and hereby does waive,  all claims for Defects of which Buyer has
not provided Seller notice on or before the Defect Claim Date.

         (e) Seller shall have the right, but not the obligation, to attempt, at
Seller's  sole cost, to cure or remove on or before the Closing Date any Defects
of which Seller has been notified by Buyer in  accordance  with Section 9(d). If
the Defect is not cured prior to the Closing Date, the adjustment required under
this Section 9 shall be made  pursuant to this Section 9.  Seller's  election to
attempt to cure a Defect  shall not  constitute  a waiver of  Seller's  right to
dispute the existence, nature or value of, or cost to cure, the Defect.

         (f) With  respect  to each  Lease,  Unit or Well  affected  by  Defects
reported in accordance  with Section 9(d), the Net Profits  Royalties  burdening
such Lease, Unit or Well shall nevertheless be assigned to and acquired by Buyer
at Closing,  subject to all uncured Defects, and the Sale Price shall be reduced
by an amount ("Defect Amount") equal to the reduction in the Allocated Value for
the Net Profits  Royalties  burdening  such  Lease,  Unit or Well caused by such
Defects, as determined pursuant to Section 9(h).

         (g) Seller  makes no warranty or  representation  as to the quantity or
quality  of  title  to the  Properties.  Buyer  releases,  remises  and  forever
discharges  Seller  and its  Affiliates  and  all  such  Persons'  stockholders,
officers,  directors,  employees,  agents, advisors and representatives from any
and all suits, legal or administrative  proceedings,  claims, demands,  damages,
losses, costs,  liabilities,  interest or causes of action whatsoever, in law or
in equity,  known or unknown,  which Buyer might now or  subsequently  may have,
based on, relating to or arising out of, any Defect or other deficiency in title
or environmental condition relating to the Properties.  Buyer affirms that Buyer
has relied  exclusively on its own  independent  investigation  of all title and
environmental conditions relating to the Properties,  including all Defects, and
that  Buyer  has  not  relied  on  Seller  or on  any  of  the  representatives,
consultants, or advisors engaged by or on behalf of Seller.

         (h) The Defect  Amount  resulting  from a Defect shall be determined as
follows:

                  (i) if Buyer  and  Seller  agree on the  Defect  Amount,  that
amount shall be the Defect Amount;

                  (ii) if the  Title  Defect  is a lien,  encumbrance,  cause of
action,  claim,  or other charge which is undisputed  and  liquidated in amount,
then the Defect Amount shall be the  liquidated  amount  necessary to be paid to
remove,  cure or  remediate  the  Defect,  but only to the extent such amount is
chargeable  as  Production  Costs (as such  term is  defined  in the  applicable
instrument set forth on Attachment 1 of Exhibit A) to the Net Profits  Royalties
in accordance with the instruments set forth on Attachment 1 of Exhibit A;

                  (iii) if the Title Defect is that (A) the net revenue interest
for  any  Lease,  Unit or Well is less  than  (B) the net  revenue  interest  or
percentage  stated on Attachment 2 of Exhibit A, then the Defect Amount shall be
the product of the Allocated Value of the Net Profits  Royalties  burdening such
Lease,  Unit or Well  multiplied  by a fraction,  the  numerator of which is the
actual net revenue interest or percentage ownership and the denominator of which
is the net revenue  interest or percentage  ownership  stated on Attachment 2 of
Exhibit A, provided  that if the Defect does not affect the Lease,  Unit or Well
throughout its entire  productive life, the Defect Amount  determined under this
Section  9(h)(iii)  shall be reduced to take into  account the  applicable  time
period only;

                                       10
<PAGE>

                  (iv)  if  the   Title   Defect   represents   an   obligation,
encumbrance,  burden or  charge  upon or other  defect in title to the  affected
Lease,  Unit  or  Well of a type  not  described  in  Sections  9(h)(i)  through
9(h)(iii)  above,  the Defect  Amount shall be determined by taking into account
the Allocated Value of the Net Profits  Royalties  burdening such Lease, Unit or
Well so affected,  the portion of Seller's interest in the Net Profits Royalties
burdening the Lease,  Unit or Well  affected by the Defect,  the legal effect of
the Defect, the potential economic effect of the Defect over the life of the Net
Profits Royalties  burdening the affected Lease, Unit or Well, the values placed
upon the Defect by Buyer and Seller and such other  factors as are  necessary to
make a proper evaluation;

                  (v) if the  Defect  is an  Environmental  Defect,  the  Defect
Amount shall be the lesser of (A) the costs and expenses  necessary to remediate
the portion of the Subject  Assets  burdened by the Net Profits  Royalties,  but
only to the extent such costs and expenses are  chargeable as  Production  Costs
(as such term is defined in the applicable  instrument set forth on Attachment 1
of Exhibit A) to the Net Profits  Royalties in accordance  with the  instruments
set forth on  Attachment  1 of Exhibit A, or (B) an amount  equal to the adverse
economic effect of the Defect on the Properties;

                  (vi) notwithstanding  anything to the contrary in this Section
9, (A) an individual  claim for a Defect for which a claim notice is given prior
to the Defect  Claim Date shall only  generate an  adjustment  to the Sale Price
under this Section 9 if the Defect Amount with respect  thereto  exceeds  twenty
thousand dollars ($20,000.00),  (B) the aggregate Defect Amounts attributable to
the effects of all Title  Defects upon the Net Profits  Royalties  burdening any
given  Lease,  Unit or Well  shall not  exceed  the  Allocated  Value of the Net
Profits  Royalties  burdening such Lease, Unit or Well and (C) there shall be no
adjustment to the Sale Price for Defects  unless and until the aggregate  Defect
Amounts that are entitled to an  adjustment  under Section  9(h)(vi)(A)  and for
which Claim Notices were  properly  delivered on or before the Defect Claim Date
exceed two  percent  (2%) of the  unadjusted  Sale  Price,  and then only to the
extent  that such  aggregate  Defect  Amounts  exceed  two  percent  (2%) of the
unadjusted Sale Price;

                  (vii) if a Defect is reasonably  susceptible of being cured or
remediated,  the Defect Amount determined under Sections 9(h)(iii),  (iv) or (v)
above  shall not be greater  than the  reasonable  cost and expense of curing or
remediating  such  Defect,  but only to the extent such costs and  expenses  are
chargeable  as  Production  Costs (as such  term is  defined  in the  applicable
instruments set forth on Attachment 1 of Exhibit A) to the Net Profits Royalties
in accordance with the instrument set forth on Attachment 1 of Exhibit A;

                  (viii) if a Title Defect is attributable to any asserted claim
or cause of action that has not been finally  adjudicated  or resolved  prior to
the Closing  Date,  the Defect  Amount with  respect to such Title  Defect shall
equal the amount,  if any, that may be reasonably  determined based on the final
adjudication  or  resolution  of  such  claim  or  cause  of  action,   as  such
adjudication or resolution may be reasonably determined based on the facts known
to the Parties hereto as of the Closing Date; and

                  (ix) the  Defect  Amount  with  respect  to a Defect  shall be
determined without duplication of any costs or losses included in another Defect
Amount  hereunder,   or  for  which  Buyer  otherwise  receives  credit  in  the
calculation of the Sale Price.

         (i) Notwithstanding  anything herein to the contrary, in the event that
the aggregate of all Defect Amounts  attributable to Environmental  Defects that
Buyer has validly  asserted in  accordance  with this  Section 9 exceeds  twenty
percent (20%) of the unadjusted  Sale Price,  then Seller may elect, in its sole
discretion,  to terminate this Agreement by delivering  written notice to Seller
prior to the Closing.

         (j) Seller and Buyer  shall  attempt to agree on all Defect  Amounts by
the Closing  Date.  If Seller and Buyer are unable to agree by the Closing Date,
Seller's estimate shall be used to determine the adjusted Sale Price pursuant to
Section 15, and the Defect Amounts in dispute shall be  exclusively  and finally
resolved by arbitration  pursuant to this Section 9(i). During the 15-day period
following  the Closing  Date,  Defect  Amounts in dispute  with respect to Title
Defects  shall  be  submitted  to  a  title  attorney  or  attorneys  reasonably
satisfactory to Buyer and to Seller having at least ten (10) years of experience
in oil and gas title review and  examination  in the state where the  Properties
subject to the disputed Title Defects are located ("Title  Arbitrator").  During
the 15-day period  following the Closing  Date,  Defect  Amounts in dispute with
respect to Environmental Defects shall be submitted to E.Vironment or such other
environmental  consulting  firm as may be  reasonably  agreed  upon by  Buyer or
Seller ("Environmental Arbitrator" and with the Title Arbitrator, each a "Defect
Arbitrator".).  The Defect  Arbitrators  shall not have  worked as an  employee,
consultant or outside counsel for either Party or its Affiliates during the five
(5) year period preceding the arbitration or have any financial  interest in the
dispute. The arbitration  proceedings shall be held in Houston,  Texas and shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association, to the extent such rules do not conflict with the terms
of this Section 9. The Defect  Arbitrators'  determination  shall be made within
thirty (30) days after  submission  of the matters in dispute and shall be final
and  binding  upon  the  Parties,   without  right  of  appeal.  In  making  his
determination,  the applicable Defect Arbitrator shall be bound by the rules set
forth in Sections  9(h) and may consider such other matters as in the opinion of
the  applicable  Defect  Arbitrator  are  necessary  or helpful to make a proper
determination.  Additionally, each applicable Defect Arbitrator may consult with
and engage disinterested third Persons to advise the arbitrator, including title
attorneys  from other states and petroleum  engineers.  Each  applicable  Defect
Arbitrator  shall act as an expert for the limited  purpose of  determining  the
specific  disputed  Defect  Amounts  submitted  by any  Party  and may not award
damages,  interest or penalties to any Party with respect to any matter.  Seller
and Buyer shall each bear its own legal fees and other costs of  presenting  its
case.  Buyer  shall  bear  one-half  of the costs and  expenses  of each  Defect
Arbitrator,  and Seller  shall  bear the  remaining  one-half  of such costs and
expenses.

10. Consents and Preferential Rights.

         (a) Promptly  after the date hereof,  Seller shall prepare and send (i)
notices to the holders of any required consents to assignment,  if any, that are
set forth on Schedule 10 requesting consents to the transactions contemplated by
this  Agreement and (ii) notices to the holders of any  applicable  preferential
rights to purchase or similar rights,  if any, that are set forth on Schedule 10
in  compliance  with the terms of such  rights  and  requesting  waivers of such
rights.  Any preferential  purchase right must be exercised subject to all terms
and conditions set forth in this Agreement,  including the successful Closing of
this  Agreement  pursuant to Section 20. The  consideration  payable  under this
Agreement  for any  particular  Property for purposes of  preferential  purchase
right notices shall be the Allocated  Value for such Property.  Seller shall use
commercially reasonable efforts to cause such consents to assignment and waivers
of preferential  rights to purchase or similar rights (or the exercise  thereof)
to be obtained and delivered prior to Closing, provided that Seller shall not be
required to make payments or undertake  obligations to or for the benefit of the
holders of such rights in order to obtain the  required  consents  and  waivers.
Buyer shall use  commercially  reasonable  efforts to  cooperate  with Seller in
seeking to obtain  such  consents  to  assignment  and  waivers of  preferential
rights.

         (b) In no event shall there be  transferred at Closing any Property for
which a consent  requirement  has not been  satisfied and for which  transfer is
prohibited or a fee is payable (and which has not been paid by Buyer).  In cases
in which the Property  subject to such a requirement  is a Contract and Buyer is
assigned  the Net  Profits  Royalties  to which the  Contract  relates,  but the
Contract is not  transferred to Buyer due to the unwaived  consent  requirement,
Buyer shall continue  after Closing to use  commercially  reasonable  efforts to
obtain  the  consent  so that such  Contract  can be  transferred  to Buyer upon
receipt of the consent,  the Contract shall be held by Seller for the benefit of
Buyer,  Buyer  shall  pay  all  amounts  due  thereunder,  and  Buyer  shall  be
responsible for the  performance of any  obligations  under such Contract to the
extent that Buyer has been transferred the Properties necessary to perform under
such  Contract  until such consent is  obtained.  In cases in which the Property
subject to such a  requirement  is a Net Profits  Royalty  and the third  Person
consent to the  transfer of the Net Profits  Royalty is not obtained by Closing,
Buyer may elect to treat the  unsatisfied  consent  requirements as a Defect and
receive the appropriate adjustment to the unadjusted Sale Price under Section 15
by giving Seller  written  notice  thereof in accordance  with Section 9, except
that such  notice may be given up to one (1)  Business  Day prior to the Closing
Date. If an unsatisfied  consent requirement with respect to which an adjustment
to the unadjusted Sale Price is made under Section 15 is subsequently  satisfied
prior to the date of the final  adjustment  to the  unadjusted  Sale Price under
Section 30, Seller shall be reimbursed in that final  adjustment  for the amount
of any  previous  deduction  from the  unadjusted  Sale  Price,  the Net Profits
Royalty, if not previously  transferred to Buyer, shall be transferred,  and the
provisions  of this  Section  10(b)  shall  no  longer  apply  to  such  consent
requirement.

                                       12
<PAGE>

         (c) If any  preferential  right to purchase any Properties is exercised
prior to Closing,  (i) the Sale Price shall be decreased by the Allocated  Value
for such  Properties,  (ii) the affected  Properties shall not be transferred at
Closing,  (iii) the  affected  Properties  shall be deemed  to be  deleted  from
Exhibit A for all purposes,  (iv) Seller shall convey the affected Properties to
the holder of the preferential right to purchase on the terms and provisions set
out in the applicable preferential right provision, (v) Seller shall be entitled
to the  consideration  paid by such holder;  and (vi) the effective  date of the
sale of the affected  Properties shall be the Effective Time,  regardless of the
actual closing date of such sale.

         (d)  Should a third  Person  fail to  validly  exercise  or  waive  its
preferential  right to  purchase as to any  portion of the  Properties  prior to
Closing and the time for  exercise or waiver has  expired,  then  subject to the
remaining  provisions of this Section 10, such  Properties  shall be included in
the transaction at Closing and there shall be no adjustment to the Sale Price at
Closing with respect to such preferential right to purchase.

         (e) Should a third  Person fail to  exercise or waive its  preferential
right to purchase as to any portion of the  Properties  prior to Closing and the
time for exercise or waiver has not yet expired,  then subject to the  remaining
provisions of this Section 10(e),  such Properties shall be transferred to Buyer
at Closing,  there shall be no adjustment to the Purchase  Price at Closing with
respect to such  preferential  right to purchase,  and Seller shall, at its sole
expense,  continue to use commercially  reasonable efforts to obtain a waiver of
the  preferential  purchase  rights and shall continue to be responsible for the
compliance  therewith.  Should the  holder of the  preferential  purchase  right
validly  exercise such right after  Closing,  then:  (i) the Sale Price shall be
decreased  by the  Allocated  Value  for  such  Properties,  (ii)  the  affected
Properties shall be deemed to be deleted from Exhibit A for all purposes,  (iii)
Buyer shall promptly  convey the affected  Properties to the holder on the terms
and provisions set out in the applicable preferential right provision,  and (iv)
Seller shall be entitled to the consideration paid by such holder.

11.  Physical  and  Environmental  Inspection.   After  the  execution  of  this
Agreement,  Seller shall use  commercially  reasonable  efforts (but in no event
shall Seller be required to make any payments or incur any other  obligations to
any Person) to cause Buyer and its authorized  representatives  to have physical
access to the  Properties  and  Subject  Assets at Buyer's  sole cost,  risk and
expense  for  the  purpose  of  inspecting  the  same,  conducting  such  tests,
examination,  investigations  and assessments as may be reasonable and necessary
or  appropriate  to evaluate the  environmental  and  physical  condition of the
Properties  and  Subject  Assets.  Buyer's  right  of  access,  if  any,  to the
Properties  and Subject  Assets shall not entitle Buyer to operate  equipment or
conduct  intrusive  testing or  sampling,  and any such access  shall be further
limited by the Persons with rights to own,  operate or use the Subject Assets or
the surface rights burdened thereby.  Buyer  acknowledges that Seller is not the
operator  or owner of the  Subject  Assets and Seller has no right or ability to
grant  Seller  access to the  Properties  or the Subject  Assets and that Seller
makes no  representations  or warranties  as to access to the  Properties or the
Subject Assets by Buyer. BUYER SHALL HOLD HARMLESS, DEFEND AND INDEMNIFY SELLER,
ITS  AFFILIATES,  THE OTHER OWNERS OF INTERESTS IN THE  PROPERTIES  AND ALL SUCH
PERSONS' DIRECTORS,  OFFICERS,  EMPLOYEES,  AGENTS AND REPRESENTATIVES  FROM AND
AGAINST  ANY AND ALL  LIABILITY,  CLAIMS,  LOSSES,  CAUSES OF ACTION,  COSTS AND
EXPENSES  (INCLUDING  COURT COSTS AND  REASONABLE  ATTORNEYS'  FEES),  INJURY TO
BUYER'S EMPLOYEES, AGENTS, CONTRACTORS, SUBCONTRACTORS OR INVITEES OR TO BUYER'S
PROPERTY, AND/OR INJURY TO SELLER'S PROPERTY,  EMPLOYEES,  AGENTS OR CONTRACTORS
WHICH MAY  ARISE OUT OF OR ARE  ATTRIBUTABLE  TO  ACCESS  TO THE  PROPERTIES  OR
BUYER'S  INSPECTIONS  THEREOF,  ,  EVEN IF  CAUSED  IN  WHOLE  OR IN PART BY THE
NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT),  STRICT LIABILITY OR OTHER LEGAL
FAULT OF ANY INDEMNIFIED PERSON. Buyer agrees to provide to Seller a copy of any
environmental assessments, including any reports, data, and conclusions. Any and
all data or  information  acquired by all such  examinations  and results of all
analysis  of such  data and  information  shall be  subject  to the terms of the
Confidentiality Agreement.

                                       13

12.  Period  Pending  Closing.  Except as may be  required  by the terms of this
Agreement or as may be approved by Buyer in writing,  from the date hereof until
the Closing  Date Seller  shall not  transfer,  sell,  hypothecate,  encumber or
otherwise  dispose  of any of the  Properties.  Buyer's  approval  of any action
restricted by this Section 12 shall not be unreasonably  withheld or delayed and
shall be  considered  granted  within  ten (10) days  (unless a shorter  time is
reasonably  required by the  circumstances and such shorter time is specified in
Seller's  notice) of Seller's  notice to Buyer  requesting  such consent  unless
Buyer notifies  Seller to the contrary during that period.  Notwithstanding  the
foregoing  provisions of this Section 12, in the event of an  emergency,  Seller
may take such action as may be  reasonably  necessary  and shall notify Buyer of
such action promptly thereafter.

13. [Intentionally Deleted]

14. Notification of Breaches. Until the Closing,

         (a) Buyer shall  notify  Seller  promptly  after Buyer  obtains  actual
knowledge  that any  representation  or  warranty  of Seller  contained  in this
Agreement  is untrue in any  material  respect or will be untrue in any material
respect as of the Closing Date or that any covenant or agreement to be performed
or observed by Seller  prior to or on the Closing Date has not been so performed
or observed in any material respect;

         (b) Seller shall  notify Buyer  promptly  after Seller  obtains  actual
knowledge  that  any  representation  or  warranty  of Buyer  contained  in this
Agreement  is untrue in any  material  respect or will be untrue in any material
respect as of the Closing Date or that any covenant or agreement to be performed
or observed by Buyer prior to or on the Closing  Date has not been so  performed
or observed in any material respect; and

         (c) If any of Buyer's or  Seller's  representations  or  warranties  is
untrue  or shall  become  untrue in any  material  respect  between  the date of
execution  of this  Agreement  and the  Closing  Date,  or if any of  Buyer's or
Seller's  covenants or agreements to be performed or observed prior to or on the
Closing  Date  shall not have been so  performed  or  observed  in any  material
respect,  but such breach of  representation or warranty or  non-performance  of
covenant or  agreement  shall (if  curable) be cured by the Closing  (or, if the
Closing  does not  occur,  by the date set forth in  Section  16(a)),  then such
breach  shall  be  considered  not to have  occurred  for all  purposes  of this
Agreement.

15.  Sale Price  Adjustments.  The  unadjusted  Sale Price  shall be adjusted as
follows,  but only with respect to matters (i) in the case of Section 15(a), for
which notice is given on or before the Defect  Claim Date,  and (ii) in the case
of Sections  15(b),  (c), (d),  (e), (f), (g), (h) (i) and (j)  identified on or
before the February 1, 2008:

         (a) Decreased, as appropriate, in accordance with Section 9;

         (b) Decreased as a consequence  of Properties  being excluded from this
transaction as a consequence of the exercise of preferential rights to purchase,
as described in Section 10;

         (c)  Increased by the  aggregate  amount  (using a settlement  price of
three dollars ($3.00) per thousand cubic feet (Mcf)) that the Subject Assets are
underproduced,  if at all, as to the Net Profits  Royalties  share of total oil,
condensate,  gas or end product production,  any balancing  obligation or credit
arising from such underproduction,  and any pipeline imbalance underproduced, in
each case determined as of the Effective Time;

         (d)  Decreased by the  aggregate  amount  (using a settlement  price of
three dollars ($3.00) per thousand cubic feet (Mcf)) that the Subject Assets are
overproduced,  if at all,  as to the Net Profits  Royalties  share of total oil,
condensate,  gas or end product production,  any balancing  obligation or credit
arising from such overproduction,  and any pipeline imbalance  overproduced,  in
each case determined as of the Effective Time;

                                       14
<PAGE>

         (e) Decreased by an amount equal to the amounts received by Seller that
are  attributable to the ownership of the Properties for periods on or after the
Effective Time and received by Seller on or prior to the Closing Date;

         (f) Increased by the expenses paid by Seller that are  attributable  to
the ownership of the Properties for periods on or after the Effective Time;

         (g) Decreased by an amount equal to the portion of the Allocated  Value
of any  Properties  transferred  or sold by Seller during the period on or after
July 1,  2007  but  prior  to the  Closing  Date;  provided,  however,  that any
decreases  made under this Section  15(g) shall be shall be  determined  without
duplication of any costs or losses included in another adjustment,  or for which
Buyer  otherwise  receives credit in the calculation of the Sale Price and shall
exclude any transfer or sale of any  Properties  to Buyer or its  Affiliates  at
Closing as contemplated hereunder;

         (h) Increased by a positive amount, if any, equal to (i) ninety percent
(90%)  of  the  total  proved  discounted  future  net  income  aggregate  value
(discounted  at ten percent  (10%)) of all of the Subject  Assets as of December
31, 2006 as shown in the reserve  report to be delivered by Ryder Scott  Company
after  the date of this  Agreement  and prior to  November  30,  2007  ("Revised
Reserve Report") minus (ii) $28,241,400 (such amount representing ninety percent
(90%)  of  the  total  proved  discounted  future  net  income  aggregate  value
(discounted at ten percent (10%)) as reported in the reserve report covering the
Subject  Assets  delivered  by Ryder  Scott  Company  dated July 16, 2007 ("July
Reserve Report") minus (iii) ninety percent (90%) of the total proved discounted
future net income  aggregate  value,  discounted at ten percent (10%),  of those
Subject Assets set forth on Schedule 15(h) attached hereto (as such value is set
forth in the Revised Reserve Report);

         (i) In the event  that the  forward  price of West  Texas  Intermediate
Crude Oil for December 2008 as posted by the New York Mercantile  Exchange as of
the close of trading on the Business Day immediately  preceding the Closing Date
("Closing  Date WTI Price") is less then  seventy  four dollars and eighty cents
($74.80),  then  decreased  by an amount  equal to the  product  of (i) the Sale
Price, as adjusted under clauses (a) through (h) of this Section 15,  multiplied
by (ii) five tenths  ((0.50),  multiplied  by (iii) the  remainder of (A) ninety
five one hundredths  (0.95),  minus (B) the quotient of (1) the Closing Date WTI
Price,  divided by (2) seventy  eight  dollars and seventy  four cents  (78.74);
provided,  however,  the  adjustment to the Sale Price  provided in this Section
15(i) shall in no event exceed ten percent (10%) of the Sale Price,  as adjusted
under clauses (a) through (h) of this Section 15;

         (j) In the event that the  Closing  Date WTI Price  exceeds  eighty two
dollars and sixty eight cents ($82.68), then increased by an amount equal to the
product of (i) the Sale Price, as adjusted under clauses (a) through (h) of this
Section 15,  multiplied  by (ii) twenty five  hundredths  (0.25),  multiplied by
(iii) the  remainder  of (A) the  quotient  of (1) the  Closing  Date WTI Price,
divided by (2) seventy eight dollars and seventy four cents  (78.74),  minus (B)
one hundred and five one hundredths (1.05);

         (k) Decreased by an amount equal to the Deposit; and

         (l) In the event that  closing does not occur on or prior to the Target

under clauses (a) through (j) above,  multiplied by (B)(y) the number of days in
the period from the Target  Closing Date through and  including the Closing Date
divided by (z) 365. As used herein, the term "Agreed Rate" shall mean the lesser
of (i) the one month London  Inter-Bank  Offered  Rate, as published on Telerate
Page  3750 on the last  Business  Day  prior to the  Effective  Time,  plus five
percentage  points  (LIBOR +5%) and (ii) the maximum rate allowed by  applicable
Law.

The adjustments set forth in this Section 15 shall be determined in the order of
priority set forth in this Section 15, with the intent of the Parties being that
the  adjustment set forth in Section 15(a) shall be made prior to the adjustment
set forth in Section 15(b) and the  adjustment  set forth in Section 15(b) shall
be made prior to the  adjustment  set forth in Section  15(c),  and so on and so
forth.  The amount of each  adjustment to the unadjusted Sale Price described in
Sections  15(e),  and 15(g) shall be determined  in  accordance  with the United
States generally accepted accounting principles.

16.      Termination.

by any breach or default or failure to proceed by Buyer would be  impossible  or
extremely  impractical to ascertain and that the amount of the Deposit is a fair
and reasonable estimate of such damage.

                  (i) caused by or arising out of or resulting  from the Assumed
Obligations,

                  (ii)  otherwise  caused by or arising out of or resulting from
the ownership,  use or operation of the Properties,  whether before or after the
Closing Date,

                  (iii)  caused by or arising out of or  resulting  from Buyer's
breach of any of Buyer's covenants or agreements contained herein, or

                  (iv) caused by or arising out of or resulting  from any breach
of any  representation  or  warranty  made by Buyer  contained  herein or in any
certificate delivered by Buyer at Closing pursuant to Section 20,

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE  NEGLIGENCE  (WHETHER
SOLE,  JOINT  OR  CONCURRENT),  STRICT  LIABILITY  OR OTHER  LEGAL  FAULT OF ANY
INDEMNIFIED  PERSON,  but  excepting in each case Damages  against  which Seller

notice is presented by Buyer.

         (d)  Seller  Indemnification.  From and  after  Closing,  Seller  shall
indemnify,  defend and hold harmless Buyer and its  Affiliates  from and against
any and all Damages incurred or suffered by Buyer or any of Buyer's Affiliates:

breach of any of Seller's covenants or agreements contained in Section 12,

                  (ii) caused by or arising out of or resulting  from any breach

connection with the negotiation,  execution or delivery of this Agreement or any
agreement or transaction contemplated hereby,

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE  NEGLIGENCE  (WHETHER
SOLE,  JOINT  OR  CONCURRENT),  STRICT  LIABILITY  OR OTHER  LEGAL  FAULT OF ANY
INDEMNIFIED PERSON.

         (e)  Notwithstanding   anything  to  the  contrary  contained  in  this
Agreement, Seller's and Buyer's exclusive remedy against each other with respect
to breaches of the representations,  warranties, covenants and agreements of the
Parties  contained in Sections 6 through 14  (excluding  Sections 9 or 10, which
shall be  separately  enforceable  by Seller  pursuant  to  whatever  rights and
remedies are available to it outside of this Section 23) and the affirmations of
such  representations,  warranties,  covenants and  agreements  contained in the
certificates  delivered by Buyer at Closing pursuant to Section 20, is set forth
in this Section 23 (and,  where  applicable  with respect to Section 16). Except
for the  remedies  contained  in this  Section 23 and  Section 16, and any other
remedies available to the Parties at law or in equity for breaches of provisions
of this  Agreement  other than Sections 6 through 8 or 11 through 14, Seller and

administrative   proceedings,   claims,   demands,   damages,   losses,   costs,
liabilities,  interest,  or causes of action  whatsoever,  in law or in  equity,
known or unknown,  which such Parties might now or subsequently  may have, based
on, relating to or arising out of this Agreement or Seller's  ownership,  use or
operation of the Properties, or the condition,  quality, status or nature of the
Properties,   including   rights  to   contribution   under  the   Comprehensive
Environmental  Response,  Compensation  and  Liability  Act of 1980, as amended,
breaches of statutory  and implied  warranties,  nuisance or other tort actions,
rights to punitive damages, common law rights of contribution,  any rights under
insurance  policies  and any  rights  under  agreements  between  Seller and any
Affiliate  of  Seller,  EVEN IF  CAUSED  IN WHOLE  OR IN PART BY THE  NEGLIGENCE
(WHETHER SOLE,  JOINT OR CONCURRENT),  STRICT  LIABILITY OR OTHER LEGAL FAULT OF
ANY RELEASED PERSON.  Without limiting the generality of the preceding sentence,
Buyer  agrees  that its only  remedy  with  respect  to  Seller's  breach of its
covenants and agreements in Sections 8, 10, 11, 12 and 14 shall be the indemnity
of Seller in Section 23(d),  as limited by the terms of this Section 23, and, if
applicable, as set forth in Section 16.

                                       20
<PAGE>

         (f) The indemnity to which each Party is entitled under this Section 23
shall be for the  benefit  of and  extend to such  Party's  current  and  former
Affiliates and its and their  respective  directors,  officers,  employees,  and
agents.  Any claim for  indemnity  under this Section 23 by any such  Affiliate,
director,  officer,  employee or agent must be brought and  administered  by the
applicable Party to this Agreement.  No Indemnified Person other than Seller and
Buyer shall have any rights  against  either  Seller or Buyer under the terms of
this Section 23 except as may be exercised on its behalf by Buyer or Seller,  as
applicable,  pursuant to this Section 23(f).  Each of Seller and Buyer may elect
to exercise or not exercise  indemnification rights under this Section on behalf
of the other Indemnified  Persons  affiliated with it in its sole discretion and
shall have no liability to any such other  Indemnified  Person for any action or
inaction under this Section.

         (g) This Section 23 shall not apply in respect of title matters,  which
are  exclusively  covered by Section 9, or Tax  matters,  which are  exclusively
covered by Sections 27 and 28.

         (h) The Parties shall treat,  for Tax purposes,  any amounts paid under
this Section 23 as an adjustment to the applicable Sale Price.

24.  Indemnification  Actions.  All claims for indemnification  under Section 23
shall be asserted and resolved as follows:

         (a)  The  term  "Indemnifying  Person"  when  used in  connection  with
particular  Damages  shall mean the Person  having an  obligation  to  indemnify
another  Person or Persons with respect to such Damages  pursuant to Section 23,
and the term  "Indemnified  Person"  when  used in  connection  with  particular
Damages shall mean a Person having the right to be  indemnified  with respect to
such  Damages  pursuant to Section 23  (including,  for the  avoidance of doubt,
those Persons identified in Section 23(f)).

         (b)  To  make  a  claim  for  indemnification   under  Section  23,  an
Indemnified Person shall notify the Indemnifying Person of its claim,  including
the specific  details of and specific  basis under this  Agreement for its claim
("Claim Notice").  In the event that the claim for indemnification is based upon
a claim by a third  Person  against  the  Indemnified  Person (a  "Claim"),  the
Indemnified Person shall provide its Claim Notice promptly after the Indemnified
Person has actual  knowledge of the Claim and shall enclose a copy of all papers
(if any)  served  with  respect to the Claim;  provided  that the failure of any
Indemnified  Person to give  notice of a Claim as  provided  in this  Section 24
shall not relieve the  Indemnifying  Person of its obligations  under Section 23
except to the extent such failure results in  insufficient  time being available
to permit the  Indemnifying  Person to  effectively  defend against the Claim or
otherwise  prejudices the  Indemnifying  Person's  ability to defend against the
Claim.  In the  event  that the  claim  for  indemnification  is  based  upon an
inaccuracy or breach of a representation,  warranty,  covenant or agreement, the
Claim Notice shall specify the representation,  warranty,  covenant or agreement
that was inaccurate or breached.

                                       21
<PAGE>

         (c) In the case of a claim for indemnification  based upon a Claim, the
Indemnifying  Person  shall have  thirty (30) days from its receipt of the Claim
Notice  to notify  the  Indemnified  Person  whether  it  admits  or denies  its
obligation  to defend the  Indemnified  Person  against  such  Claim  under this
Section 24. If the  Indemnifying  Person does not notify the Indemnified  Person
within such thirty (30) day period  regarding  whether the  Indemnifying  Person
admits or denies its obligation to defend the  Indemnified  Person,  it shall be
conclusively  deemed obligated to provide such  indemnification  hereunder.  The
Indemnified  Person is  authorized,  prior to and during  such  thirty  (30) day
period,  to file any  motion,  answer  or  other  pleading  that it  shall  deem
necessary or appropriate  to protect its interests or those of the  Indemnifying
Person and that is not prejudicial to the Indemnifying Person.

         (d) If the Indemnifying Person admits its obligation, it shall have the
right and  obligation to diligently  defend,  at its sole cost and expense,  the
Claim.  The  Indemnifying  Person  shall have full  control of such  defense and
proceedings, including any compromise or settlement thereof. If requested by the
Indemnifying  Person,  the Indemnified  Person agrees to cooperate in contesting
any Claim which the Indemnifying  Person elects to contest  (provided,  however,
that the Indemnified  Person shall not be required to bring any  counterclaim or
cross-complaint  against any Person). The Indemnified Person may participate in,
but not  control,  any  defense or  settlement  of any Claim  controlled  by the
Indemnifying  Person pursuant to this Section 24. An  Indemnifying  Person shall
not, without the written consent of the Indemnified Person,  settle any Claim or
consent to the entry of any judgment  with respect  thereto that does not result
in a final,  complete  and  unconditional  release of the  Indemnified  Person's
liability with respect to the Claim.

         (e) If the Indemnifying  Person does not admit its obligation or admits
its  obligation  but fails to  diligently  defend or settle the Claim,  then the
Indemnified Person shall have the right to defend against the Claim (at the sole
cost and  expense  of the  Indemnifying  Person,  if the  Indemnified  Person is
entitled to indemnification hereunder), with counsel of the Indemnified Person's
choosing,  subject  to the  right  of  the  Indemnifying  Person  to  admit  its
obligation  to indemnify  the  Indemnified  Person and assume the defense of the
Claim at any time prior to settlement  or final  determination  thereof.  If the
Indemnifying  Person  has not yet  admitted  its  obligation  to  indemnify  the
Indemnified  Person,  the  Indemnified  Person shall send written  notice to the
Indemnifying Person of any proposed settlement and the Indemnifying Person shall
have the option for ten (10) days following  receipt of such notice to (i) admit
in writing its  obligation  for  indemnification  with respect to such Claim and
(ii)  if its  obligation  is so  admitted,  assume  the  defense  of the  Claim,
including the power to reject the proposed settlement. If the Indemnified Person
settles  any Claim  over the  objection  of the  Indemnifying  Person  after the
Indemnifying  Person has timely admitted its obligation for  indemnification  in
writing and assumed the defense of the Claim,  the  Indemnified  Person shall be
deemed to have waived any right to indemnity therefor.

         (f) In the case of a claim for  indemnification not based upon a Claim,
the  Indemnifying  Person  shall have  thirty  (30) days from its receipt of the
Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to
provide  indemnification with respect to such Damages or (iii) dispute the claim
for such Damages.  If the  Indemnifying  Person does not notify the  Indemnified
Person  within such thirty (30) day period that it has cured the Damages or that
it  disputes  the claim  for such  Damages,  the  Indemnifying  Person  shall be
conclusively deemed obligated to provide indemnification hereunder.

25.  Limitation on Actions.

         (a) The  representations  and warranties of the Seller in Section 6 and
the covenants  and  agreements of Seller in Section 12 shall survive the Closing
for a period of three  (3)  months  after  Closing.  All other  representations,
warranties and covenants of Seller shall terminate as of the Closing Date.

         (b) The remainder of this Agreement  shall survive the Closing  without
time   limit   except  as  may   otherwise   be   expressly   provided   herein.
Representations,  warranties,  covenants and  agreements  shall be of no further
force and effect after the date of their  expiration,  provided that there shall
be no  termination  of any bona fide claim  asserted  pursuant to this Agreement
with respect to such a representation,  warranty, covenant or agreement prior to
its expiration date.

                                       22
<PAGE>

         (c)  The  indemnities  in  Section  23(d)  shall  terminate  as of  the
termination  date of  each  respective  representation,  warranty,  covenant  or
agreement that is subject to indemnification,  except in each case as to matters
for which a specific  written  claim for  indemnity  has been  delivered  to the
Indemnifying  Person on or before such  termination  date.  The  indemnities  in
Section 23(c) shall continue without time limit.

         (d) Seller shall not have any liability for any  indemnification  under
Section  23 until and  unless  the  aggregate  amount of the  liability  for all
Damages for which Claim  Notices are delivered by Buyer exceeds two percent (2%)
of the  unadjusted  Sale  Price,  and then only to the extent the amount of such
Damages exceeds two percent (2%) of the unadjusted Sale Price.

         (e)  Notwithstanding  anything to the contrary  contained  elsewhere in
this Agreement, Seller shall not be required to indemnify Buyer under Section 23
for aggregate  Damages in excess of twenty five percent (25%) of the  unadjusted
Sale Price.

         (f) The  amount  of any  Damages  for  which an  Indemnified  Person is
entitled  to  indemnity  under  Section 23 shall be reduced by the amount of any
insurance  proceeds  realized by the  Indemnified  Person or its Affiliates with
respect to such Damages (net of any collection costs).

26. Casualty and Condemnation. If, after the date of this Agreement but prior to
Closing  Date,  any  portion of the  Properties  is  destroyed  by fire or other
casualty or is  expropriated  or taken in condemnation or under right of eminent
domain,  Buyer shall  nevertheless  be required to close.  In the event that the
amount  of the  diminutions  in value  of the  Properties  attributable  to such
casualty,  expropriation  or taking  (determined  by reference to the  Allocated
Value,  determined in the same manner as a Defect in accordance with Section 9),
exceeds fifty thousand  dollars  ($50,000.00),  Seller and Buyer shall treat the
diminution  of  value  of  the   Properties   attributable   to  such  casualty,
expropriation or taking (determined by reference to Allocated Value) as a Defect
under  Section 9. In each case,  Seller shall retain all rights to insurance and
other claims against third Persons with respect to the casualty or taking except
to the extent the Parties otherwise agree in writing.

27. Taxes. All ad valorem Taxes,  real property Taxes,  and similar  obligations
with respect to the Tax period in which the Effective  Time occurs (the "current
Tax period") shall be  apportioned  between Seller and Buyer as of the Effective
Time  based  on the  current  Tax  period  assessment.  Seller  shall  pay,  and
indemnify,  defend and hold Buyer  harmless  with respect to payment of all such
Taxes on the Properties  for the current Tax period,  together with any interest
or penalties assessed thereon.  Buyer shall pay, and indemnify,  defend and hold
Seller  harmless with respect to payment of all such Taxes on the Properties for
any time  subsequent  to the current Tax period,  together  with any interest or
penalties assessed thereon.

28. Sales Tax;  Recording  Fees. The Sale Price provided for hereunder  excludes
any sales Taxes or other Taxes in connection with the sale  contemplated by this
Agreement.  If a  determination  is ever made that a sales Tax or other transfer
Tax  applies,  Buyer  shall be  liable  for  such Tax as well as any  applicable
conveyance,  transfer and recording  fees,  and real estate  transfer  stamps or
Taxes  imposed on any  transfer of property  pursuant to this  Agreement.  Buyer
shall indemnify,  defend and hold Seller harmless with respect to the payment of
all such Taxes, if any,  including any interest or penalties  assessed  thereon.
Notwithstanding  other provisions of this Agreement,  Buyer shall be responsible
for the prompt filing and  recording of the  conveyances,  assignments  or other
instruments  required  to  convey  title  to  the  Properties  to  Buyer  in the
appropriate federal,  state and local records.  Buyer shall supply Seller with a
true and accurate  photocopy of all the recorded and filed conveyances  within a
reasonable period of time after such are available and in any event within sixty
(60) days after the Closing Date.

                                       23

29. Records.  Within ten (10) days after the Closing Date,  Seller shall deliver
or cause to be  delivered  to Buyer any Records  that are in the  possession  of
Seller,  subject to this  Section 28.  Seller may retain the  originals of those
Records  relating  to Tax and  accounting  matters  and  provide  Buyer,  at its
request,  with copies of such  Records that  pertain to  non-income  Tax matters
solely related to the Properties. Seller may retain copies of any other Records.
Buyer, for a period of seven (7) years following the Closing,  shall: (i) retain
the Records, (ii) provide Seller, its Affiliates, and their respective officers,
employees and representatives  with access to the Records during normal business
hours for review and copying at Seller's  expense,  (iii)  provide  Seller,  its
Affiliates,  and their respective  officers,  employees and representatives with
access for,  during normal  business  hours,  to materials  received or produced
after Closing relating to (A) Seller's  obligations under Section 27, or (B) any
claim  for  indemnification  made  under  Sections  23 or 28 of  this  Agreement
(excluding,  however,  attorney work product and attorney-client  communications
with respect to any such claim being brought by Buyer under this Agreement), for
review and copying at Seller's expense, and (iv) provide Seller, its Affiliates,
and their respective  officers,  employees and representatives  with access for,
during normal business hours, to Buyer's personnel for the purpose of discussing
any such matter or claim described in Section 29(iii).

30. Post-Closing Adjustments; Revenues.

         (a) As soon as reasonably  practicable  after the Closing but not later
than  the  later of (i) the  February  1,  2007  and (ii) the date on which  the
Parties or the Defect Arbitrators, as applicable,  finally determines all Defect
Amounts  under  Section 9,  Seller  shall  prepare  and deliver to Buyer a draft
statement  setting forth the final calculation of the Sale Price and showing the
calculation of each adjustment under Section 15, based on the most recent actual
figures for each  adjustment.  Seller shall at Buyer's  request make  reasonable
documentation  available  to support the final  figures.  As soon as  reasonably
practicable  but not later than the fifteenth  (15th) day  following  receipt of
Seller's  statement  hereunder,  Buyer shall deliver to Seller a written  report
containing any changes that Buyer proposes be made in such statement. Seller may
deliver a written report to Buyer during this same period reflecting any changes
that Seller  proposes  to be made in such  statement  as a result of  additional
information  received  after the  statement  was  prepared.  The  Parties  shall
undertake to agree on the final statement of the Sale Price no later than thirty
(30) days after  delivery of Seller's  statement.  In the event that the Parties
cannot reach agreement within such period of time, any Party may refer the items
of  adjustment  which  are in  dispute  to Grant  Thornton  LLP or to any  other
nationally-recognized  independent  accounting  firm or consulting firm mutually
acceptable to both Buyer and Seller  ("Accounting  Arbitrator"),  for review and
final determination by arbitration.  The Accounting Arbitrator shall conduct the
arbitration  proceedings  in Houston,  Texas in accordance  with the  Commercial
Arbitration Rules of the American  Arbitration  Association,  to the extent such
rules  do  not  conflict  with  the  terms  of  this  Section.   The  Accounting
Arbitrator's   determination  shall  be  made  within  thirty  (30)  days  after
submission  of the  matters  in  dispute  and shall be final and  binding on all
Parties,  without  right of appeal.  In  determining  the  proper  amount of any
adjustment to the Sale Price,  the Accounting  Arbitrator  shall be bound by the
terms of Section 15 and may not  increase  the Sale Price more than the increase
proposed by Seller nor decrease  the Sale Price more than the decrease  proposed
by Buyer, as applicable.  The Accounting  Arbitrator  shall act as an expert for
the limited purpose of determining the specific  disputed  aspects of Sale Price
adjustments  submitted by any Party and may not award damages,  interest (except
as  expressly  provided  for in this  Section)  or  penalties  to any Party with
respect to any  matter.  Seller and Buyer shall each bear its own legal fees and
other costs of presenting  its case.  Seller shall bear one-half and Buyer shall
bear one-half of the costs and expenses of the Accounting Arbitrator. Within ten
(10) days after the earlier of (i) the  expiration  of Buyer's  fifteen (15) day
review period  without  delivery of any written report or (ii) the date on which
the Parties or the Accounting  Arbitrator  finally determine the Sale Price, (x)
Buyer  shall pay to Seller the amount by which the  adjusted  Sale Price paid by
Buyer to Seller on the Closing  Date  exceeds the final  adjusted  Sale Price as
determined  pursuant  to this  Section 30 or (y)  Seller  shall pay to Buyer the
amount by which the final  adjusted  Sale Price as  determined  pursuant to this
Section  30  exceeds  the  adjusted  Sale  Price  paid by Buyer to Seller on the
Closing Date,  as  applicable.  Any  post-adjusted  Sale Price  pursuant to this
Section 30 shall bear  interest  from the Closing Date to the date of payment at
the Agreed Interest Rate.  Buyer shall assist Seller in preparation of the final
statement  of the Sale Price  under  this  Section  30 by  furnishing  invoices,
receipts,  reasonable  access to personnel  and such other  assistance as may be
requested by Seller to facilitate such process post-Closing.

         (b) With respect to any proceeds  attributable  to the ownership of the
Properties  prior to the Effective Time that are received after the Closing Date
(other  than the  Suspended  Royalties),  Seller  shall be  entitled to all such
proceeds.  Should Buyer  receive  after  Closing any proceeds to which Seller is
entitled under the immediately  foregoing sentence,  Buyer shall fully disclose,
account  for and  promptly,  but in no event  later than  thirty (30) days after
receipt, remit the same to Seller.

         (c) With respect to any proceeds  attributable  to (i) the ownership of
the  Properties on or after the Effective  Time or (ii) the Suspended  Royalties
that are, in each case, received after the Closing Date, Buyer shall be entitled
to all such proceeds.  Should Seller or its Affiliates receive after Closing any
proceeds to which Buyer is entitled under the  immediately  foregoing  sentence,
Seller shall fully  disclose,  account for and  promptly,  but in no event later
than thirty (30) days after receipt, remit the same to Buyer.

Agreement and the transactions contemplated hereby.

38. Entire Agreement.  This Agreement and the Confidentiality  Agreement and the
agreements  and  instruments  contemplated  hereby and thereby  state the entire
agreement  between the Parties  regarding the subject  matter hereof and thereof
and may be supplemented,  altered, amended, modified or revoked by writing only,
signed by both Parties.  This Agreement  supersedes any prior agreements between

the interpretations of this Agreement.

completed in the manner  required by Section 1060 of the Code.  Buyer and Seller

40. Assignability. This Agreement and the rights and obligations hereunder shall
not be assignable or delegable by either Party hereto  without the prior written
consent  of the  other,  which  consent  may be  given or  withheld  at the sole
discretion  of the Party  entitled to grant such  consent,  and any  transfer or
delegation made without such consent shall be void.  Notwithstanding anything to
the contrary in this Section 40, Buyer may, prior to Closing,  assign its rights
hereunder to a wholly-owned  Affiliate of Buyer by delivering to Seller prior to
Closing an  assignment  agreement in form and substance  mutually  acceptable to
Seller;  provided,  however,  such assignment shall not release, and Buyer shall
remain liable for, all obligations to be performed by Buyer under this Agreement

action brought in the United States federal courts located in the State of Texas
with respect to any dispute,  claim or controversy arising out of or in relation
to or in connection with this  Agreement,  and each of the Parties hereto agrees
that any  action  instituted  by it against  the other with  respect to any such
dispute,  controversy or claim (except to the extent a dispute,  controversy, or
claim arising out of or in relation to or in connection  with the  allocation of
the Sale  Price  pursuant  to Section 5, the  determination  of a Defect  Amount
pursuant to Section 9 or the determination of Sale Price adjustments pursuant to
Section  15 is  referred  to an  expert  pursuant  to  those  Sections)  will be

any action,  proceeding or counterclaim  brought by any Party against another in
any matter  whatsoever  arising out of or in relation to or in  connection  with
this Agreement.

43.  Counterpart  Execution.  This Agreement may be executed in counterparts and
each  counterpart  shall  constitute  a binding  agreement as if the Parties had
executed a single document.

44. Severance of Invalid Provisions.  If, for any reason and for so long as, any
clause  or  provision  of  this  Agreement  is  held  by a  court  of  competent
jurisdiction to be illegal,  invalid,  unenforceable or unconscionable under any
present  or  future  Law (or  interpretation  thereof),  the  remainder  of this
Agreement  shall not be  affected by such  illegality  or  invalidity.  Any such
invalid  provision  shall be  deemed  severed  from  this  Agreement  as if this
Agreement had been executed with the invalid provision eliminated. The surviving
provisions  of this  Agreement  shall remain in full force and effect unless the
removal  of the  invalid  provision  destroys  the  legitimate  purpose  of this
Agreement;  in which event this  Agreement  shall be null and void.  The Parties
shall negotiate in good faith for any required modifications to this Agreement.

                        CERTIFICATE OF NON-FOREIGN SELLER

         Section 1445 of the Internal Revenue Code provides that a transferee of
a U.S. real property  interest must withhold tax if the  transferor is a foreign
person.  For U.S. tax purposes  (including  section 1445 of the Internal Revenue
Code),  the owner of a disregarded  entity (which has legal title to a U.S. real
property  interest  under local law) will be the  transferor of the property and
not the disregarded  entity. To inform the transferee,  Amen Properties,  LLC, a
Delaware  corporation,  ("Buyer"),  that withholding of tax is not required upon
the  disposition of a U.S. real property  interest by The Bank of New York Trust
Company, N.A. ("BNY") solely in its capacity of trustee of Santa Fe Energy Trust
(the Trust") (BNY, in its capacity as trustee of the Trust,  being herein called
"Trustee";  and the Trustee,  in its  capacity as the seller of the  properties,
being called herein "Seller"), the undersigned hereby certifies the following on
behalf of the Trust and the Seller:

1. [Seller is a national association;

2. Trust is a trust;

3. Neither Seller nor the Trust is a foreign  corporation,  foreign partnership,
foreign  trust,  or foreign  estate (as those terms are defined in the  Internal
Revenue Code and Income Tax Regulations);

4. Neither  Seller nor the Trust is a disregarded  entity as defined in Treasury
Regulations Section 1.1445-2(b)(b)(2)(iii);

5. Seller's U.S. employer identification number is __________________;

6. Trust's U.S. employer identification number is __________________;

7. Seller's office address is: 303 _______________________________;

8. Trust's office address is: _______________________________.]

         Seller  understands  that this  certification  may be  disclosed to the
Internal Revenue Service by Buyer and that any false statement  contained herein
could be punished by fine, imprisonment, or both.

         Under  penalties  of  perjury  I  declare  that  I have  examined  this
certification  and to the best of my knowledge  and belief it is true,  correct,
and complete,  and I further declare that I have authority to sign this document
on behalf of Seller.
                                      SELLER:

2.  Sale  and  Purchase.  Subject  to and  upon  all of the  terms,  conditions,
reservations and exceptions  hereinafter set forth, Seller shall sell, transfer,
assign,  convey and deliver the Properties to Buyer,  and Buyer shall  purchase,
receive,  pay for and accept the  Properties  from  Seller,  effective as of the
Effective Time.

materially  consistent with the differences between the information set forth in
the July  Reserve  Report and the  Revised  Reserve  Report  (after  taking into
account the values set forth on the original  Exhibit B attached  hereto and the
proposed  amended  Exhibit B) and,  within three (3)  Business  Days of Seller's
receipt of such amendment,  Seller provides  written notice to Buyer that Seller
objects  to such  amendment.  Seller  has  accepted  such  Allocated  Values for
purposes  of  this  Agreement  and the  transactions  contemplated  hereby,  but
otherwise makes no representation or warranty as to the accuracy of such values.

the Closing Date (as hereinafter defined):

                                       5
<PAGE>

         (a)  Qualification  and Power.  Seller is validly  existing and in good
standing under the Laws of its  jurisdiction of formation and has full power and
authority to enter into and perform this Agreement  (and all documents  required
to be  executed  and  delivered  by Seller at  Closing)  and to  consummate  the
transactions contemplated by this Agreement (and such documents).

         (b) Authorization. Seller's execution, delivery and performance of this
Agreement (and all documents required to be executed by Seller at Closing),  and
the consummation of the transactions  contemplated hereby and thereby, have been
duly and validly authorized by Seller. This Agreement has been duly executed and
delivered by Seller (and all documents  required to be executed and delivered by
Seller at Closing  will be duly  executed  and  delivered  by  Seller)  and this
Agreement  constitutes,  and at the Closing such documents will constitute,  the
valid and binding  obligations of Seller,  enforceable in accordance  with their
terms except as such  enforceability may be limited by applicable  bankruptcy or
other similar Laws  affecting the rights and remedies of creditors  generally as
well  as  to  general   principles  of  equity   (regardless   of  whether  such
enforceability is considered in a proceeding in equity or at law).

         (c) Enforceability. This Agreement has been duly executed and delivered
on behalf of Seller and constitutes  the legal and binding  obligation of Seller
enforceable  in  accordance  with its  terms,  except as  enforceability  may be
limited  by  applicable  bankruptcy,   reorganization,  or  moratorium  statues,
equitable  principles,  or other similar laws  affecting the rights of creditors
generally ("Equitable  Limitations").  At Closing, all documents and instruments
required to be executed  and  delivered  by Seller  shall be duly  executed  and
delivered  and  shall  constitute  legal,   valid,   enforceable,   and  binding
obligations  of Seller,  except as  enforceability  may be limited by  Equitable
Limitations.

         (d)  Title.  Seller  has  Marketable  Title  to the  Property.  For the
purposes of this Agreement, "Marketable Title" means such title that will enable
Buyer, as Seller's successor in title, to receive from each of the Properties at
least  the  "net  revenue  interest"  shown on  Exhibit  A,  without  reduction,
suspension,  or termination  throughout the productive life of the Wells, except
for any reduction,  suspension,  or  termination:  (i) in connection  with those
operations in which those  Properties are subject to any  non-consent or similar
penalties;  (ii)  resulting from reversion of interest to co-owners with respect
to operations in which such  co-owners  elected not to consent;  (iii) caused by
orders of the appropriate  regulatory agency having jurisdiction over a Property
that  are  promulgated  after  the  Effective  Date and  that  concern  pooling,
unitization,  communitization  or spacing  matters  affecting a  Property;  (iv)
required to allow other working interest owners to make up past  underproduction
or pipelines to make up past  underdeliveries;  (v) caused by Buyer,  any of its
affiliates,  successors  in  title  or  assigns;  (vi)  caused  by any  Contract
containing a  sliding-scale  royalty clause or other similar clause with respect
to a  production  burden  associated  with  a  particular  Property;  or,  (vii)
otherwise  set out in Exhibit A.  "Marketable  Title" also means title that will
obligate  Buyer,  as Seller's  successor in title,  to bear no greater  "Working
Interest" than the Working  Interest for each of the wells identified on Exhibit
A as being associated with each of the Properties,  without increase  throughout
the productive life of the Wells, except for any increase:  (i) caused by Buyer,
any of its affiliates, successors in title or assigns; (ii) that also results in
the  Net  Revenue  Interest  associated  with  the  Well  being  proportionately
increased;   (iii)  caused  by  contribution  requirements  provided  for  under
provisions similar to those contained in an A.A.P.L.  Form Operating  Agreement;
(iv) caused by orders of the appropriate  regulatory agency having  jurisdiction
over a Property that are  promulgated  after the Effective Date and that concern
pooling, unitization, communitization, or spacing matters affecting a particular
Property;  or, (v)  otherwise  set forth in Exhibit A.  "Marketable  Title" also
means the  Properties  are free and clear of all  encumbrances,  liens,  claims,
easements,  rights, agreements,  instruments,  obligations,  burdens, or defects
(collectively the "Liens"), except for Permitted Encumbrances.

         (e) Litigation and Claims.  To Seller's actual  knowledge and except as
would not have a material  adverse effect on the Properties in the aggregate and
except as is set forth on Schedule  6(e),  no claim,  demand,  filing,  cause of
action,  administrative proceeding,  lawsuit, or other litigation is pending, or
threatened that could now or later  adversely  affect the ownership or operation
of any of the  Properties,  other  than  proceedings  relating  to the  industry
generally and to which Seller is not a named party. To Seller's actual knowledge
and except as would not have a material  adverse  effect on the  Properties,  no
written or oral notice from any governmental agency or any other person has been
received by Seller: (i) claiming any violation or repudiation of all or any part
of the Properties or any violation of any law or any environmental, conservation
or other  ordinance,  code,  rule or  regulation;  or,  (ii)  require or calling
attention  to the need for any  work,  repairs,  construction,  alterations,  or
installations on or in connection with the Properties, with which Seller has not
complied.

approvals required to be obtained by Seller for the assignment of the Properties
to Buyer, and all preferential purchase rights that affect the Properties.

necessary  governmental  certificates,  consents,  permits,  licenses,  or other
authorizations  with regard to the ownership or operation of the Properties have
been obtained and no  violations  exist or have been recorded in respect of such
licenses,  permits  or  authorizations;  and  (iii)  none of the  documents  and

the  Properties  contains any untrue  statement of a material  fact or omits any
statement of a material fact necessary to make the statement not misleading.

Contracts;  and (iii) no other party has given or  threatened  to give notice of
any  default,  inquired  into any  possible  default,  or taken action to alter,
terminate,  rescind, or procure a judicial  reformation of any Contract.  Seller
does not  anticipate any other party to a Contract will be in breach of, default
under,  or repudiate any of its  obligations  of a Contract,  to the extent such
breach,  default,  or  repudiation  will have a material  adverse  effect on the
Properties in the aggregate.

         (i)  Production  Burdens,  Taxes,  and  Expenses.  To  Seller's  actual
knowledge  and  except  as  would  not have a  material  adverse  effect  on the
Properties in the aggregate and provided that this representation does not apply
to any  obligation  Seller  may owe to the Santa Fe Energy  Trust or Bank of New
York Trust Company,  N.A.,  solely in its capacity as trustee of Santa Fe Energy

prior to delinquency, in the ordinary course of business.

         (j) Production  Balances.  To Seller's  actual  knowledge and except as

except as  described  in Schedule  6(j):  (i) none of the  purchasers  under any
production  sales  contracts  are  entitled  to "makeup"  or  otherwise  receive
deliveries of oil or gas at any time after the Effective Date without paying, at

to  receive  any  portion  of the  interest  of Seller in any oil or gas,  or to
receive cash or other payments to "balance" any  disproportionate  allocation of
oil or gas under any operating  agreement,  gas balancing and storage agreement,
gas processing or dehydration agreement, or other similar agreements.

         (k) Current  Commitments.  To Seller's  actual  knowledge and except as

9. Defects.

         (a) For the purpose of this Agreement,  a "Defect" shall mean any Title
Defect or Environmental Defect.

         (b) "Title Defect" shall mean any lien,  charge,  obligation,  cause of
action,  claim or title defect  burdening the  Properties,  other than Permitted
Encumbrances, that:

                  (i) Subject to the Net Profits Royalties,  entitles the Seller
to receive at any time  throughout the duration of the productive life of any of
the Leases,  Units or Wells, LESS THAN the "net revenue interest" share shown in
Exhibit A of all oil, gas and other minerals  produced,  saved and marketed from
such Asset,  except decreases in connection with those operations in which those
Assets are subject to any non-consent or similar penalties,  decreases resulting
from reversion of interest to co-owners with respect to operations in which such
co-owners elected not to consent,  decreases resulting from the establishment or
amendment  of pools or units,  and  decreases  required to allow  other  working
interest  owners to make up past  underproduction  or  pipelines to make up past
underdeliveries and except as stated in Exhibit A;

                  (ii)  Subject  to the Net  Profits  Royalties,  obligates  the
portion of the Assets  burdened by the to bear at any time a  percentage  of the
costs and  expenses  for the  maintenance  and  development  of, and  operations
relating to, any Lease, Unit or Well NOT GREATER THAN of the "working  interest"
shown in  Exhibit A without  increase  throughout  the  productive  life of such
Asset,  except as  stated  in  Exhibit A and  except  increases  resulting  from
contribution  requirements with respect to defaulting co-owners under applicable
operating  agreements or applicable Law and increases that are accompanied by at
least a proportionate increase in the net revenue interest.

         (c) "Environmental Defect" shall mean, except for any matters set forth
on Schedule 9(c) attached hereto,  the failure of the ownership and operation of
the Assets to be in material  compliance with all applicable  Environmental Laws
or any contamination of groundwater, surface water, soil or seabed on the Assets
resulting from  hydrocarbon  activities on such Assets required to be remediated
under applicable  Environmental Laws on or before the date of this Agreement, in
each  case  that  are  chargeable  to the  Properties  but  which  have not been
remediated,  provided,  however,  the presence or absence of naturally occurring
radioactive material ("NORM"), asbestos, mercury, drilling fluids and chemicals,
and produced waters and  hydrocarbons in or on the Assets in quantities  typical
for oilfield operations in the areas in which the Assets are located shall in no
event constitute an "Environmental  Defect".  "Environmental Laws" means, as the
same have been  amended  to the date  hereof,  the  Comprehensive  Environmental
Response,  Compensation  and  Liability  Act, 42 U.S.C.  ss.  9601 et seq.;  the

         (d) To assert a claim for any Defect, Buyer must deliver a claim notice
or notices to Seller on or before the date ten (10)  Business  Days prior to the
Target Closing Date ("Defect Claim Date").  Each such notice shall be in writing
and shall include: (i) a description of the alleged Defect(s);  (ii) the Leases,
Units or Wells  affected;  (iii) the  Allocated  Values of the Leases,  Units or
Wells subject to the alleged  Defect(s);  (iv) supporting  documents  reasonably
necessary for Seller (as well as any title attorney, environmental consultant or
examiner hired by Seller) to verify the existence of the alleged Defect(s);  and
(v) the amount by which Buyer reasonably  believes the Allocated Values of those
Leases, Units or Wells are reduced by the alleged Defect(s) and the computations
and  information  upon which Buyer's  belief is based.  Buyer shall be deemed to
have  waived,  and hereby does waive,  all claims for Defects of which Buyer has
not provided Seller notice on or before the Defect Claim Date.

         (e) Seller shall have the right, but not the obligation, to attempt, at
Seller's  sole cost, to cure or remove on or before the Closing Date any Defects
of which Seller has been notified by Buyer in  accordance  with Section 9(d). If
the Defect is not cured prior to the Closing Date, the adjustment required under
this Section 9 shall be made  pursuant to this Section 9.  Seller's  election to
attempt to cure a Defect  shall not  constitute  a waiver of  Seller's  right to
dispute the existence, nature or value of, or cost to cure, the Defect.

         (f) With  respect  to each  Lease,  Unit or Well  affected  by  Defects
reported in accordance  with Section  9(d),  the Assets  affected  thereby shall
nevertheless  be  assigned to and  acquired by Buyer at Closing,  subject to all
uncured  Defects,  and the Sale Price  shall be  reduced  by an amount  ("Defect
Amount")  equal to the reduction in the Allocated  Value caused by such Defects,
as determined pursuant to Section 9(h).

         (g) Seller  makes no warranty or  representation  as to the quantity or
quality  of  title  to the  Properties.  Buyer  releases,  remises  and  forever
discharges  Seller  and its  Affiliates  and  all  such  Persons'  stockholders,
officers,  directors,  employees,  agents, advisors and representatives from any
and all suits, legal or administrative  proceedings,  claims, demands,  damages,
losses, costs,  liabilities,  interest or causes of action whatsoever, in law or
in equity,  known or unknown,  which Buyer might now or  subsequently  may have,
based on, relating to or arising out of, any Defect or other deficiency in title
or environmental condition relating to the Properties.  Buyer affirms that Buyer
has relied  exclusively on its own  independent  investigation  of all title and
environmental conditions relating to the Properties,  including all Defects, and
that  Buyer  has  not  relied  on  Seller  or on  any  of  the  representatives,
consultants, or advisors engaged by or on behalf of Seller.

         (h) The Defect  Amount  resulting  from a Defect shall be determined as
follows:

                  (i) if Buyer  and  Seller  agree on the  Defect  Amount,  that
amount shall be the Defect Amount;

                  (ii) if the  Defect is a lien,  encumbrance,  cause of action,
claim or other charge which is undisputed  and  liquidated  in amount,  then the
Defect  Amount shall be the  liquidated  amount  necessary to be paid to remove,
cure or remediate  the Defect,  but only to the extent such amount is chargeable
to the Assets;

                  (iii) if the Defect is that (A) the net revenue  interest  for
any Lease,  Unit or Well is less than (B) the net revenue interest or percentage
stated  on  Exhibit  A,  then the  Defect  Amount  shall be the  product  of the
Allocated Value of the such Lease,  Unit or Well  multiplied by a fraction,  the
numerator of which is the actual net revenue  interest or  percentage  ownership
and the denominator of which is the net revenue interest or percentage ownership
stated on Exhibit A, provided that if the Defect does not affect the Lease, Unit
or Well  throughout its entire  productive  life,  the Defect Amount  determined
under  this  Section  9(h)(iii)  shall  be  reduced  to take  into  account  the
applicable time period only;

                                       11
<PAGE>

                  (iv) if the  Defect  represents  an  obligation,  encumbrance,
burden or charge upon or other  defect in title to the affected  Lease,  Unit or
Well of a type not described in Sections  9(h)(i) through  9(h)(iii)  above, the
Defect Amount shall be determined by taking into account the Allocated  Value of
such Lease,  Unit or Well so affected,  the portion of Seller's  interest in the
Lease, Unit or Well affected by the Defect,  the legal effect of the Defect, the
potential  economic  effect of the Defect over the life of the  affected  Lease,
Unit or Well,  the  values  placed  upon the Defect by Buyer and Seller and such
other factors as are necessary to make a proper evaluation;

                  (v) if the Defect is of the type  described  in Section  9(c),
the Defect Amount shall be the lesser of (A) the costs and expenses necessary to
remediate  the  portion of the  Assets,  but only to the  extent  such costs and
expenses  are  chargeable  to the Assets,  or (B) an amount equal to the adverse
economic effect of the Defect on the Properties;

                  (vi) notwithstanding  anything to the contrary in this Section
9, (A) an individual  claim for a Defect for which a claim notice is given prior
to the Defect  Claim Date shall only  generate an  adjustment  to the Sale Price
under this  Section 9 if the Defect  Amount with  respect  thereto  exceeds five
thousand dollars  ($5,000.00),  (B) the aggregate Defect Amounts attributable to
the effects of all Title  Defects upon any given  Lease,  Unit or Well shall not
exceed the Allocated Value of such Lease, Unit or Well and (C) there shall be no
adjustment to the Sale Price for Defects  unless and until the aggregate  Defect
Amounts that are entitled to an  adjustment  under Section  9(h)(vi)(A)  and for
which Claim Notices were  properly  delivered on or before the Defect Claim Date
exceed ten percent  (10%) of the  unadjusted  Sale  Price,  and then only to the
extent  that such  aggregate  Defect  Amounts  exceed ten  percent  (10%) of the
unadjusted Sale Price;

                  (vii) if a Defect is reasonably  susceptible of being cured or
remediated,  the Defect Amount determined under Sections 9(h)(iii),  (iv) or (v)
above  shall not be greater  than the  reasonable  cost and expense of curing or
remediating  such  Defect,  but only to the extent such costs and  expenses  are
chargeable to the Assets; and

                  (viii) the Defect  Amount  with  respect to a Defect  shall be
determined without duplication of any costs or losses included in another Defect
Amount  hereunder,   or  for  which  Buyer  otherwise  receives  credit  in  the
calculation of the Sale Price.

         (i) Seller and Buyer  shall  attempt to agree on all Defect  Amounts by
the Closing  Date.  If Seller and Buyer are unable to agree by the Closing Date,
Seller's estimate shall be used to determine the adjusted Sale Price pursuant to
Section 14, and the Defect Amounts in dispute shall be  exclusively  and finally
resolved by arbitration  pursuant to this Section 9(i). During the 15-day period
following  the Closing  Date,  Defect  Amounts in dispute  with respect to Title
Defects shall be submitted to a title attorney as may be reasonably  agreed upon
by Buyer or Seller ("Title Arbitrator").  During the 15-day period following the
Closing Date,  Defect Amounts in dispute with respect to  Environmental  Defects
shall be  submitted to an  environmental  consulting  firm as may be  reasonably
agreed upon by Buyer or Seller  ("Environmental  Arbitrator"  and with the Title
Arbitrator,  each a "Defect Arbitrator").  The Defect Arbitrators shall not have
worked as an  employee,  consultant  or outside  counsel for either Party or its
Affiliates during the five (5) year period preceding the arbitration or have any
financial interest in the dispute. The arbitration  proceedings shall be held in
Houston,  Texas  and  shall be  conducted  in  accordance  with  the  Commercial
Arbitration Rules of the American  Arbitration  Association,  to the extent such
rules do not conflict  with the terms of this Section.  The Defect  Arbitrators'
determination  shall be made  within  thirty (30) days after  submission  of the
matters in dispute  and shall be final and  binding  upon the  Parties,  without
right of appeal. In making his  determination,  the applicable Defect Arbitrator
shall be bound by the rules set forth in  Sections  9(h) and may  consider  such
other  matters  as in  the  opinion  of the  applicable  Defect  Arbitrator  are
necessary  or  helpful  to  make  a  proper  determination.  Additionally,  each
applicable  Defect  Arbitrator may consult with and engage  disinterested  third
Persons to advise the  arbitrator,  including  title attorneys from other states
and petroleum  engineers.  Each  applicable  Defect  Arbitrator  shall act as an
expert for the limited  purpose of  determining  the  specific  disputed  Defect
Amounts submitted by any Party and may not award damages,  interest or penalties
to any Party with  respect to any  matter.  Seller and Buyer shall each bear its
own legal fees and other costs of presenting its case. Buyer shall bear one-half
of the costs and expenses of each Defect  Arbitrator,  and Seller shall bear the
remaining one-half of such costs and expenses.

10. Consents and Preferential Rights.

         (a) Promptly  after the date hereof,  Seller shall prepare and send (i)
notices to the holders of any required consents to assignment,  if any, that are
set forth on Schedule 10 requesting consents to the transactions contemplated by
this  Agreement and (ii) notices to the holders of any  applicable  preferential
rights to purchase or similar rights,  if any, that are set forth on Schedule 10
in  compliance  with the terms of such  rights  and  requesting  waivers of such
rights.  Any preferential  purchase right must be exercised subject to all terms
and conditions set forth in this Agreement,  including the successful Closing of
this  Agreement  pursuant to Section 20. The  consideration  payable  under this
Agreement for any particular  Asset for purposes of preferential  purchase right
notices  shall  be  the  Allocated  Value  for  such  Asset.  Seller  shall  use
commercially reasonable efforts to cause such consents to assignment and waivers
of preferential  rights to purchase or similar rights (or the exercise  thereof)
to be obtained and delivered prior to Closing, provided that Seller shall not be
required to make payments or undertake  obligations to or for the benefit of the
holders of such rights in order to obtain the  required  consents  and  waivers.
Buyer shall use  commercially  reasonable  efforts to  cooperate  with Seller in
seeking to obtain  such  consents  to  assignment  and  waivers of  preferential
rights.

         (b) In no event shall there be  transferred at Closing any Property for
which a consent  requirement  has not been  satisfied and for which  transfer is
prohibited or a fee is payable (and which has not been paid by Buyer).  In cases
in which the Property  subject to such a requirement  is a Contract and Buyer is
assigned  the Asset to which  the  Contract  relates,  but the  Contract  is not
transferred  to Buyer  due to the  unwaived  consent  requirement,  Buyer  shall
continue  after  Closing to use  commercially  reasonable  efforts to obtain the
consent so that such  Contract can be  transferred  to Buyer upon receipt of the
consent,  the Contract  shall be held by Seller for the benefit of Buyer,  Buyer
shall pay all amounts due  thereunder,  and Buyer shall be  responsible  for the
performance of any obligations  under such Contract to the extent that Buyer has
been  transferred the Properties  necessary to perform under such Contract until
such  consent  is  obtained.  In cases in which the  Property  subject to such a
requirement  is an Asset the third  Person  consent  to the  transfer  it is not
obtained  by  Closing,   Buyer  may  elect  to  treat  the  unsatisfied  consent
requirements  as  a  Defect  and  receive  the  appropriate  adjustment  to  the
unadjusted  Sale Price under Section 14 by giving Seller  written notice thereof
in accordance with Section 9, except that such notice may be given up to one (1)
Business Day prior to the Closing Date. If an  unsatisfied  consent  requirement
with respect to which an adjustment to the  unadjusted  Sale Price is made under
Section 14 is subsequently  satisfied prior to the date of the final  adjustment
to the  unadjusted  Sale Price under  Section 29,  Seller shall be reimbursed in
that  final  adjustment  for the  amount  of any  previous  deduction  from  the
unadjusted Sale Price, the Asset, if not previously  transferred to Buyer, shall
be  transferred,  and the provisions of this Section 10(b) shall no longer apply
to such consent requirement.

         (c) If any preferential right to purchase any Assets is exercised prior
to Closing,  (i) the Sale Price shall be  decreased by the  Allocated  Value for
such Assets, (ii) the affected Assets shall not be transferred at Closing, (iii)
the  affected  Assets  shall be  deemed  to be  deleted  from  Exhibit A for all
purposes,  (iv) Seller  shall  convey the  affected  Assets to the holder of the
preferential  right to  purchase  on the  terms  and  provisions  set out in the
applicable preferential right provision, and (v) Seller shall be entitled to the
consideration paid by such holder.

         (d)  Should a third  Person  fail to  validly  exercise  or  waive  its
preferential  right to purchase as to any portion of the Assets prior to Closing
and the time for exercise or waiver has expired,  then subject to the  remaining
provisions of this Section 10, such Assets shall be included in the  transaction
at Closing and there shall be no  adjustment  to the Sale Price at Closing  with
respect to such preferential right to purchase.

                                       13
<PAGE>

         (e) Should a third  Person fail to  exercise or waive its  preferential
right to purchase as to any portion of the Assets  prior to Closing and the time
for  exercise  or waiver has not yet  expired,  then  subject  to the  remaining
provisions of this Section  10(e),  such Assets shall be transferred to Buyer at
Closing,  there shall be no  adjustment  to the  Purchase  Price at Closing with
respect to such  preferential  right to purchase,  and Seller shall, at its sole
expense,  continue to use commercially  reasonable efforts to obtain a waiver of
the  preferential  purchase  rights and shall continue to be responsible for the
compliance  therewith.  Should the  holder of the  preferential  purchase  right
validly  exercise such right after  Closing,  then:  (i) the Sale Price shall be
decreased by the Allocated Value for such Assets, (ii) the affected Assets shall
be deemed to be deleted  from  Exhibit A for all  purposes,  (iii)  Buyer  shall
promptly  convey the affected  Assets to the holder on the terms and  provisions
set out in the applicable preferential right provision, and (iv) Seller shall be
entitled to the consideration paid by such holder.

11.  Physical  and  Environmental  Inspection.   After  the  execution  of  this
Agreement,  Seller shall use  commercially  reasonable  efforts (but in no event
shall Seller be required to make any payments or incur any other  obligations to
any Person) to cause Buyer and its authorized  representatives  to have physical
access to the Properties  and Assets at Buyer's sole cost,  risk and expense for
the  purpose  of  inspecting  the  same,  conducting  such  tests,  examination,
investigations and assessments as may be reasonable and necessary or appropriate
to evaluate the  environmental  and physical  condition  of the  Properties  and
Assets.  Buyer's right of access, if any, to the Properties and Assets shall not
entitle Buyer to operate equipment or conduct intrusive testing or sampling, and
any such  access  shall be further  limited by the  Persons  with rights to own,
operate  or use  the  Assets  or the  surface  rights  burdened  thereby.  Buyer
acknowledges  that Seller may not be the operator or owner of all Assets and may
not have the right or  ability  to grant  Buyer  access to the  Assets  and that
Seller  makes no  representations  or  warranties  as to access to the Assets by
Buyer.  BUYER SHALL HOLD HARMLESS,  DEFEND AND INDEMNIFY SELLER, ITS AFFILIATES,
THE OTHER OWNERS OF INTERESTS IN THE PROPERTIES AND ALL SUCH PERSONS' DIRECTORS,
OFFICERS,  EMPLOYEES,  AGENTS AND  REPRESENTATIVES  FROM AND AGAINST ANY AND ALL
LIABILITY, CLAIMS, LOSSES, CAUSES OF ACTION, COSTS AND EXPENSES (INCLUDING COURT
COSTS AND REASONABLE  ATTORNEYS'  FEES),  INJURY TO BUYER'S  EMPLOYEES,  AGENTS,
CONTRACTORS, SUBCONTRACTORS OR INVITEES OR TO BUYER'S PROPERTY, AND/OR INJURY TO
SELLER'S  PROPERTY,  EMPLOYEES,  AGENTS OR CONTRACTORS WHICH MAY ARISE OUT OF OR
ARE  ATTRIBUTABLE  TO ACCESS TO THE PROPERTIES OR BUYER'S  INSPECTIONS  THEREOF,
EVEN IF CAUSED IN WHOLE OR IN PART BY THE  NEGLIGENCE  (WHETHER  SOLE,  JOINT OR
CONCURRENT),  STRICT  LIABILITY OR OTHER LEGAL FAULT OF ANY INDEMNIFIED  PERSON.
Buyer  agrees  to  provide  to Seller a copy of any  environmental  assessments,
including any reports,  data, and  conclusions.  Any and all data or information
acquired by all such  examinations  and results of all analysis of such data and
information shall be subject to the terms of the Confidentiality Agreement.

12.  Period  Pending  Closing.  Except as may be  required  by the terms of this
Agreement  or as may be approved by Buyer in writing,  until the Closing  Seller
shall not transfer,  sell, hypothecate,  encumber or otherwise dispose of any of
the Assets.  Buyer's approval of any action  restricted by this Section 12 shall
not be unreasonably  withheld or delayed and shall be considered  granted within
ten (10) days (unless a shorter time is reasonably required by the circumstances
and such shorter time is  specified  in Seller's  notice) of Seller's  notice to
Buyer  requesting  such  consent  unless Buyer  notifies  Seller to the contrary
during that period. Notwithstanding the foregoing provisions of this Section 12,
in the event of an  emergency,  Seller may take such action as may be reasonably
necessary and shall notify Buyer of such action promptly thereafter.

13. Notification of Breaches. Until the Closing,

         (a) Buyer shall  notify  Seller  promptly  after Buyer  obtains  actual
knowledge  that any  representation  or  warranty  of Seller  contained  in this
Agreement  is untrue in any  material  respect or will be untrue in any material
respect as of the Closing Date or that any covenant or agreement to be performed
or observed by Seller  prior to or on the Closing Date has not been so performed
or observed in any material respect;

                                       14
<PAGE>

         (b) Seller shall  notify Buyer  promptly  after Seller  obtains  actual
knowledge  that  any  representation  or  warranty  of Buyer  contained  in this
Agreement  is untrue in any  material  respect or will be untrue in any material
respect as of the Closing Date or that any covenant or agreement to be performed
or observed by Buyer prior to or on the Closing  Date has not been so  performed
or observed in any material respect; and

         (c) If any of Buyer's or  Seller's  representations  or  warranties  is
untrue  or shall  become  untrue in any  material  respect  between  the date of
execution  of this  Agreement  and the  Closing  Date,  or if any of  Buyer's or
Seller's  covenants or agreements to be performed or observed prior to or on the
Closing  Date  shall not have been so  performed  or  observed  in any  material
respect,  but such breach of  representation or warranty or  non-performance  of
covenant or  agreement  shall (if  curable) be cured by the Closing  (or, if the
Closing  does not  occur,  by the date set forth in  Section  15(a)),  then such
breach  shall  be  considered  not to have  occurred  for all  purposes  of this
Agreement.

14.  Sale Price  Adjustments.  The  unadjusted  Sale Price  shall be adjusted as
follows,  but only with respect to matters (i) in the case of Section 14(b), for
which notice is given on or before the Defect  Claim Date,  and (ii) in the case
of Sections  14(c),  (d), (e), (f), and (g) identified on or before  February 1,
2008:

         (a)  Decreased by the amount of the Earnest  Money  previously  paid to
Seller;

         (b) Decreased, as appropriate, in accordance with Section 9;

transaction as a consequence of the exercise of preferential rights to purchase,
as described in Section 10;

         (d)  Increased by the  aggregate  amount  (using a settlement  price of
three  dollars  ($3.00) per  thousand  cubic feet  ("Mcf"))  that the Assets are
underproduced,  if at all, as to the Assets share of total oil, condensate,  gas
or end product production,  any balancing obligation or credit arising from such
underproduction,   and  any  pipeline  imbalance  underproduced,  in  each  case
determined as of the Effective Time;

         (e)  Decreased by the  aggregate  amount  (using a settlement  price of
three dollars ($3.00) per Mcf) that the Assets are  overproduced,  if at all, as
to the Assets share of total oil, condensate, gas or end product production, any
balancing  obligation  or  credit  arising  from  such  overproduction,  and any
pipeline  imbalance  overproduced,  in each case  determined as of the Effective
Time;

         (f) Decreased by an amount equal to the amounts received by Seller that
are  attributable  to the  ownership  of the Assets for  periods on or after the
Effective Time and received by Seller on or prior to the Closing Date;

         (g) Increased by the expenses paid by Seller that are  attributable  to
the ownership of the Assets for periods on or after the Effective Time; and

         (h) Increased by a positive  amount,  if any,  equal to (i) ten percent
(10%)  of  the  total  proved  discounted  future  net  income  aggregate  value
(discounted  at ten percent  (10%)) of all of the Assets as of December 31, 2006
as shown in the reserve  report to be delivered by Ryder Scott Company after the
date of this Agreement and prior to November 30, 2007 ("Revised Reserve Report")
minus (ii) $3,137,933  (such amount  representing ten percent (10%) of the total
proved  discounted  future net income aggregate value (discounted at ten percent
(10%)) as reported in the reserve report  covering the Subject Assets  delivered
by Ryder Scott Company dated July 16, 2007 ("July  Reserve  Report") minus (iii)
ten percent  (10%) of the total proved  discounted  future net income  aggregate
value,  discounted at ten percent  (10%),  of those Assets set forth on Schedule
15(h)  attached  hereto  (as such  value is set  forth  in the  Revised  Reserve
Report).

                                       15
<PAGE>

The amount of each adjustment to the unadjusted Sale Price described in Sections
14(f) and  14(g)  shall be  determined  in  accordance  with the  United  States
generally accepted accounting principles.

15.      Termination.

         (a) Right of Termination.  This Agreement may be terminated at any time
prior to Closing:  (i) by the mutual prior written  consent of Seller and Buyer;

Section 17 has not been satisfied or waived by Buyer by December 31, 2007.

         (b)      Effect of Termination.

                  (i) If this  Agreement  is  terminated  by  Seller  and  Buyer
pursuant to Section  15(a)(i)  above,  Seller  shall  return the  Earnest  Money
(without interest) to Buyer promptly after such termination.

                  (ii) If this  Agreement  is  terminated  by Buyer  pursuant to
Section 15(a)(ii) above, then Seller shall, as Buyer's exclusive remedy,  return
the Earnest Money (without interest) to Buyer promptly after such termination.

                  (iii) If this  Agreement is terminated  by Seller  pursuant to
Section  15(a)(iii)  above,  then Seller shall be entitled to retain the Earnest
Money as liquidated damages and as reimbursement for Seller's out-of-pocket fees
and expenses  incurred in connection with the transactions  contemplated by this
Agreement  and  Seller  may,  at  its  option,  assert  its  right  of  specific
performance. The Parties hereby acknowledge that the extent of damages to Seller
occasioned  by such  breach or default  or failure to proceed by Buyer  would be
impossible  or extremely  impractical  to  ascertain  and that the amount of the
Earnest Money is a fair and reasonable estimate of such damage.

                  (iv) If this Agreement is terminated  pursuant to this Section
15, this  Agreement  shall become void and of no further force or effect (except
for the  provisions  of Section 1, 4, 8, 11, 15, 30, 32, 33, 34, 36, 40, 43, 44,
45,  and  47,  all  of  which  shall   continue  in  full  force  and   effect).
Notwithstanding  anything to the contrary in this Agreement,  the termination of
this Agreement  under this Section 15 shall not relieve any Party from liability
(including  liability  for  consequential  damages) for any willful or negligent
failure to perform or observe in any material  respect any of its  agreements or
covenants  contained  herein that are to be performed or observed at or prior to
Closing.  In the event this Agreement  terminates under Section 15 and any Party
has  willfully  or  negligently  failed to perform  or  observe in any  material
respect any of its  agreements  or  covenants  contained  herein which are to be
performed  or  observed  at or prior to  Closing,  then the other Party shall be
entitled  to  all  remedies  available  at law or in  equity  (including  strict
performance)  and shall be entitled to recover court costs and  attorneys'  fees
from the other Party in addition to any other  relief to which such Party may be
entitled.

<PAGE>

         (b) Assumed  Obligations.  Without limiting Buyer's rights to indemnity
under this Section 22, on the Closing Date Buyer shall assume and hereby  agrees
to fulfill,  perform,  pay and discharge  (or cause to be fulfilled,  performed,
paid or discharged)  all of the  obligations  and  liabilities of Seller and its
Affiliates,  known or unknown,  with respect to the  Properties,  regardless  of

production balancing obligations,  crude oil scheduling imbalances,  obligations

remove  and  dispose  of NORM,  MMMF,  asbestos,  mercury,  drilling  fluids and
chemicals, and produced waters and hydrocarbons, other environmental liabilities
with respect to the Properties and continuing obligations under the Contracts or
any  agreements  pursuant  to  which  the  Seller  or its  Affiliates  purchased
Properties  prior  to the  Closing  (all of said  obligations  and  liabilities,
subject to the  exclusions  of the proviso  below,  herein being  referred to as
"Assumed  Obligations");  provided,  however,  that  Buyer  does not  assume any
obligations to the extent that they are: (i) attributable to or arise out of the
Excluded Properties; (ii) required to be borne by Seller under Section 14; (iii)
Tax  obligations  retained  by Seller  pursuant  to Section  26 or 27;  (iv) the

indemnify,  defend and hold harmless  Seller and its Affiliates from and against
all Damages incurred or suffered by Seller or any of Seller's Affiliates:

                  (i) caused by or arising out of or resulting  from the Assumed
Obligations,

                  (ii)  otherwise  caused by or arising out of or resulting from
the ownership,  use or operation of the Properties,  whether before or after the
Closing Date,

                  (iii)  caused by or arising out of or  resulting  from Buyer's
breach of any of Buyer's covenants or agreements contained herein, or

                  (iv) caused by or arising out of or resulting  from any breach
of any  representation  or  warranty  made by Buyer  contained  herein or in any
certificate  delivered by Buyer at Closing  pursuant to Section 20, EVEN IF SUCH
DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR
CONCURRENT),  STRICT  LIABILITY OR OTHER LEGAL FAULT OF ANY INDEMNIFIED  PERSON,
but  excepting  in each case Damages  against  which Seller would be required to
indemnify Buyer under Section 22(d) at the time the claim notice is presented by
Buyer.

         (d)  Seller  Indemnification.  From and  after  Closing,  Seller  shall
indemnify,  defend and hold harmless Buyer and its  Affiliates  from and against
any and all Damages incurred or suffered by Buyer or any of Buyer's Affiliates:

                  (i) caused by or arising  out of or  resulting  from  Seller's
breach of any of Seller's covenants or agreements contained in Section 12,

                  (ii) caused by or arising out of or resulting  from any breach

connection with the negotiation,  execution or delivery of this Agreement or any
agreement or transaction contemplated hereby,

                                       19
<PAGE>

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE  NEGLIGENCE  (WHETHER
SOLE,  JOINT  OR  CONCURRENT),  STRICT  LIABILITY  OR OTHER  LEGAL  FAULT OF ANY
INDEMNIFIED PERSON.

         (e)  Notwithstanding   anything  to  the  contrary  contained  in  this
Agreement, Seller's and Buyer's exclusive remedy against each other with respect
to breaches of the representations,  warranties, covenants and agreements of the
Parties  contained in Sections 6 through 13  (excluding  Sections 9 or 10, which
shall be  separately  enforceable  by Seller  pursuant  to  whatever  rights and
remedies are available to it outside of this Section 22) and the affirmations of
such  representations,  warranties,  covenants and  agreements  contained in the
certificates  delivered by Buyer at Closing pursuant to Section 20, is set forth
in this Section 22 (and,  where  applicable  with respect to Section 15). Except
for the  remedies  contained  in this  Section 22 and  Section 15, and any other
remedies available to the Parties at law or in equity for breaches of provisions
of this  Agreement  other than Sections 6 through 8 or 11 through 13, Seller and
Buyer each  release,  remise and  forever  discharge  the other and their or its
Affiliates and all such Persons' stockholders,  officers, directors,  employees,
agents,   advisors  and  representatives  from  any  and  all  suits,  legal  or
administrative   proceedings,   claims,   demands,   damages,   losses,   costs,
liabilities,  interest,  or causes of action  whatsoever,  in law or in  equity,
known or unknown,  which such Parties might now or subsequently  may have, based
on, relating to or arising out of this Agreement or Seller's  ownership,  use or
operation of the Properties, or the condition,  quality, status or nature of the
Properties,   including   rights  to   contribution   under  the   Comprehensive
Environmental  Response,  Compensation  and  Liability  Act of 1980, as amended,
breaches of statutory  and implied  warranties,  nuisance or other tort actions,
rights to punitive damages, common law rights of contribution,  any rights under
insurance  policies  and any  rights  under  agreements  between  Seller and any
Affiliate  of  Seller,  EVEN IF  CAUSED  IN WHOLE  OR IN PART BY THE  NEGLIGENCE
(WHETHER SOLE,  JOINT OR CONCURRENT),  STRICT  LIABILITY OR OTHER LEGAL FAULT OF
ANY RELEASED PERSON.  Without limiting the generality of the preceding sentence,
Buyer  agrees  that its only  remedy  with  respect  to  Seller's  breach of its
covenants and agreements in Sections 8, 10, 11, 12 and 13 shall be the indemnity
of Seller in Section 22(d),  as limited by the terms of this Section 22, and, if
applicable, as set forth in Section 15.

         (f) The indemnity to which each Party is entitled under this Section 22
shall be for the  benefit  of and  extend to such  Party's  current  and  former
Affiliates and its and their  respective  directors,  officers,  employees,  and
agents.  Any claim for  indemnity  under this Section 22 by any such  Affiliate,
director,  officer,  employee or agent must be brought and  administered  by the
applicable Party to this Agreement.  No Indemnified Person other than Seller and
Buyer shall have any rights  against  either  Seller or Buyer under the terms of
this Section 22 except as may be exercised on its behalf by Buyer or Seller,  as
applicable,  pursuant to this Section 22(f).  Each of Seller and Buyer may elect
to exercise or not exercise  indemnification rights under this Section on behalf
of the other Indemnified  Persons  affiliated with it in its sole discretion and
shall have no liability to any such other  Indemnified  Person for any action or
inaction under this Section.

         (g) This Section 22 shall not apply in respect of title matters,  which
are  exclusively  covered by Section 9, or Tax  matters,  which are  exclusively
covered by Sections 26 and 27.

         (h) The Parties shall treat,  for Tax purposes,  any amounts paid under
this Section 22 as an adjustment to the applicable Sale Price.

23.  Indemnification  Actions.  All claims for indemnification  under Section 22
shall be asserted and resolved as follows:

         (a)  The  term  "Indemnifying  Person"  when  used in  connection  with
particular  Damages  shall mean the Person  having an  obligation  to  indemnify
another  Person or Persons with respect to such Damages  pursuant to Section 22,
and the term  "Indemnified  Person"  when  used in  connection  with  particular
Damages shall mean a Person having the right to be  indemnified  with respect to
such  Damages  pursuant to Section 22  (including,  for the  avoidance of doubt,
those Persons identified in Section 22(f)).

                                       20
<PAGE>

         (b)  To  make  a  claim  for  indemnification   under  Section  22,  an
Indemnified Person shall notify the Indemnifying Person of its claim,  including
the specific  details of and specific  basis under this  Agreement for its claim
("Claim Notice").  In the event that the claim for indemnification is based upon
a claim by a third  Person  against  the  Indemnified  Person (a  "Claim"),  the
Indemnified Person shall provide its Claim Notice promptly after the Indemnified
Person has actual  knowledge of the Claim and shall enclose a copy of all papers
(if any)  served  with  respect to the Claim;  provided  that the failure of any
Indemnified  Person to give  notice of a Claim as  provided  in this  Section 23
shall not relieve the  Indemnifying  Person of its obligations  under Section 22
except to the extent such failure results in  insufficient  time being available
to permit the  Indemnifying  Person to  effectively  defend against the Claim or
otherwise  prejudices the  Indemnifying  Person's  ability to defend against the
Claim.  In the  event  that the  claim  for  indemnification  is  based  upon an
inaccuracy or breach of a representation,  warranty,  covenant or agreement, the
Claim Notice shall specify the representation,  warranty,  covenant or agreement
that was inaccurate or breached.

         (c) In the case of a claim for indemnification  based upon a Claim, the
Indemnifying  Person  shall have  thirty (30) days from its receipt of the Claim
Notice  to notify  the  Indemnified  Person  whether  it  admits  or denies  its
obligation  to defend the  Indemnified  Person  against  such  Claim  under this
Section 23. If the  Indemnifying  Person does not notify the Indemnified  Person
within such thirty (30) day period  regarding  whether the  Indemnifying  Person
admits or denies its obligation to defend the  Indemnified  Person,  it shall be
conclusively  deemed obligated to provide such  indemnification  hereunder.  The
Indemnified  Person is  authorized,  prior to and during  such  thirty  (30) day
period,  to file any  motion,  answer  or  other  pleading  that it  shall  deem
necessary or appropriate  to protect its interests or those of the  Indemnifying
Person and that is not prejudicial to the Indemnifying Person.

         (d) If the Indemnifying Person admits its obligation, it shall have the
right and  obligation to diligently  defend,  at its sole cost and expense,  the
Claim.  The  Indemnifying  Person  shall have full  control of such  defense and
proceedings, including any compromise or settlement thereof. If requested by the
Indemnifying  Person,  the Indemnified  Person agrees to cooperate in contesting
any Claim which the Indemnifying  Person elects to contest  (provided,  however,
that the Indemnified  Person shall not be required to bring any  counterclaim or
cross-complaint  against any Person). The Indemnified Person may participate in,
but not  control,  any  defense or  settlement  of any Claim  controlled  by the
Indemnifying  Person pursuant to this Section 23. An  Indemnifying  Person shall
not, without the written consent of the Indemnified Person,  settle any Claim or
consent to the entry of any judgment  with respect  thereto that does not result
in a final,  complete  and  unconditional  release of the  Indemnified  Person's
liability with respect to the Claim.

         (e) If the Indemnifying  Person does not admit its obligation or admits
its  obligation  but fails to  diligently  defend or settle the Claim,  then the
Indemnified Person shall have the right to defend against the Claim (at the sole
cost and  expense  of the  Indemnifying  Person,  if the  Indemnified  Person is
entitled to indemnification hereunder), with counsel of the Indemnified Person's
choosing,  subject  to the  right  of  the  Indemnifying  Person  to  admit  its
obligation  to indemnify  the  Indemnified  Person and assume the defense of the
Claim at any time prior to settlement  or final  determination  thereof.  If the
Indemnifying  Person  has not yet  admitted  its  obligation  to  indemnify  the
Indemnified  Person,  the  Indemnified  Person shall send written  notice to the
Indemnifying Person of any proposed settlement and the Indemnifying Person shall
have the option for ten (10) days following  receipt of such notice to (i) admit
in writing its  obligation  for  indemnification  with respect to such Claim and
(ii)  if its  obligation  is so  admitted,  assume  the  defense  of the  Claim,
including the power to reject the proposed settlement. If the Indemnified Person
settles  any Claim  over the  objection  of the  Indemnifying  Person  after the
Indemnifying  Person has timely admitted its obligation for  indemnification  in
writing and assumed the defense of the Claim,  the  Indemnified  Person shall be
deemed to have waived any right to indemnity therefor.

         (f) In the case of a claim for  indemnification not based upon a Claim,
the  Indemnifying  Person  shall have  thirty  (30) days from its receipt of the
Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to
provide  indemnification with respect to such Damages or (iii) dispute the claim
for such Damages.  If the  Indemnifying  Person does not notify the  Indemnified
Person  within such thirty (30) day period that it has cured the Damages or that
it  disputes  the claim  for such  Damages,  the  Indemnifying  Person  shall be
conclusively deemed obligated to provide indemnification hereunder.

24. Limitation on Actions.

         (a) The covenants and  agreements of Seller in Section 12 shall survive
the Closing for a period of three (3) months after Closing.  The representations
and  warranties  of the  Seller  in  Section  6 and all  other  representations,
warranties and covenants of Seller shall terminate as of the Closing Date.

         (b) The remainder of this Agreement  shall survive the Closing  without
time   limit   except  as  may   otherwise   be   expressly   provided   herein.
Representations,  warranties,  covenants and  agreements  shall be of no further
force and effect after the date of their  expiration,  provided that there shall
be no  termination  of any bona fide claim  asserted  pursuant to this Agreement
with respect to such a representation,  warranty, covenant or agreement prior to
its expiration date.

         (c)  The  indemnities  in  Section  22(d)  shall  terminate  as of  the
termination  date of  each  respective  representation,  warranty,  covenant  or
agreement that is subject to indemnification,  except in each case as to matters
for which a specific  written  claim for  indemnity  has been  delivered  to the
Indemnifying  Person on or before such  termination  date.  The  indemnities  in
Section 22(c) shall continue without time limit.

         (d) Seller shall not have any liability for any  indemnification  under
Section  22 until and  unless  the  aggregate  amount of the  liability  for all
Damages for which Claim Notices are delivered by Buyer exceeds ten percent (10%)
of the  unadjusted  Sale  Price,  and then only to the extent the amount of such
Damages exceeds ten percent (10%) of the unadjusted Sale Price.

         (e)  Notwithstanding  anything to the contrary  contained  elsewhere in
this Agreement, Seller shall not be required to indemnify Buyer under Section 22
for aggregate  Damages in excess of twenty five percent (25%) of the  unadjusted
Sale Price.

         (f) The  amount  of any  Damages  for  which an  Indemnified  Person is
entitled  to  indemnity  under  Section 22 shall be reduced by the amount of any
insurance  proceeds  realized by the  Indemnified  Person or its Affiliates with
respect to such Damages (net of any collection costs).

25. Casualty and Condemnation. If, after the date of this Agreement but prior to
Closing  Date,  any  portion of the  Properties  is  destroyed  by fire or other
casualty or is  expropriated  or taken in condemnation or under right of eminent
domain,  Buyer shall  nevertheless  be required to close.  In the event that the
amount  of the  diminutions  in value  of the  Properties  attributable  to such
casualty,  expropriation  or taking  (determined  by reference to the  Allocated
Value,  determined in the same manner as a Defect in accordance with Section 9),
exceeds  five  thousand  dollars  ($5,000.00),  Seller and Buyer shall treat the
diminution  of  value  of  the   Properties   attributable   to  such  casualty,
expropriation or taking (determined by reference to Allocated Value) as a Defect
under  Section 9. In each case,  Seller shall retain all rights to insurance and
other claims against third Persons with respect to the casualty or taking except
to the extent the Parties otherwise agree in writing.

Time  based  on the  current  Tax  period  assessment.  Seller  shall  pay,  and
indemnify,  defend and hold Buyer  harmless  with respect to payment of all such
Taxes on the Properties  for the current Tax period,  together with any interest
or penalties assessed thereon.  Buyer shall pay, and indemnify,  defend and hold
Seller  harmless with respect to payment of all such Taxes on the Properties for
any time  subsequent  to the current Tax period,  together  with any interest or
penalties assessed thereon.

conveyance,  transfer and recording  fees,  and real estate  transfer  stamps or
Taxes  imposed on any  transfer of property  pursuant to this  Agreement.  Buyer

review and copying at Seller's expense, and (iv) provide Seller, its Affiliates,

under  Section 9, Seller  shall  prepare and deliver to Buyer a draft  statement

calculation of each adjustment under Section 14, based on the most recent actual
figures for each  adjustment.  Seller shall at Buyer's  request make  reasonable
documentation  available  to support the final  figures.  As soon as  reasonably
practicable  but not later than the fifteenth  (15th) day  following  receipt of
Seller's  statement  hereunder,  Buyer shall deliver to Seller a written  report
containing any changes that Buyer proposes be made in such statement. Seller may
deliver a written report to Buyer during this same period reflecting any changes
that Seller  proposes  to be made in such  statement  as a result of  additional
information  received  after the  statement  was  prepared.  The  Parties  shall
undertake to agree on the final statement of the Sale Price no later than thirty
(30) days after  delivery of Seller's  statement.  In the event that the Parties
cannot reach agreement within such period of time, any Party may refer the items
of  adjustment  which  are in  dispute  to Grant  Thornton  LLP or to any  other
nationally-recognized  independent  accounting  firm or consulting firm mutually
acceptable to both Buyer and Seller  ("Accounting  Arbitrator"),  for review and
final determination by arbitration.  The Accounting Arbitrator shall conduct the
arbitration  proceedings  in Houston,  Texas in accordance  with the  Commercial
Arbitration Rules of the American  Arbitration  Association,  to the extent such
rules  do  not  conflict  with  the  terms  of  this  Section.   The  Accounting
Arbitrator's   determination  shall  be  made  within  thirty  (30)  days  after
submission  of the  matters  in  dispute  and shall be final and  binding on all
Parties,  without  right of appeal.  In  determining  the  proper  amount of any
adjustment to the Sale Price,  the Accounting  Arbitrator  shall be bound by the
terms of Section 14 and may not  increase  the Sale Price more than the increase
proposed by Seller nor decrease  the Sale Price more than the decrease  proposed
by Buyer, as applicable.  The Accounting  Arbitrator  shall act as an expert for
the limited purpose of determining the specific  disputed  aspects of Sale Price
adjustments  submitted by any Party and may not award damages,  interest (except
as  expressly  provided  for in this  Section)  or  penalties  to any Party with
respect to any  matter.  Seller and Buyer shall each bear its own legal fees and
other costs of presenting  its case.  Seller shall bear one-half and Buyer shall
bear one-half of the costs and expenses of the Accounting Arbitrator. Within ten
(10) days after the earlier of (i) the  expiration  of Buyer's  fifteen (15) day
review period  without  delivery of any written report or (ii) the date on which
the Parties or the Accounting  Arbitrator  finally determine the Sale Price, (x)
Buyer  shall pay to Seller the amount by which the  adjusted  Sale Price paid by
Buyer to Seller on the Closing  Date  exceeds the final  adjusted  Sale Price as
determined  pursuant  to this  Section 29 or (y)  Seller  shall pay to Buyer the
amount by which the final  adjusted  Sale Price as  determined  pursuant to this
Section  29  exceeds  the  adjusted  Sale  Price  paid by Buyer to Seller on the
Closing Date,  as  applicable.  Any  post-adjusted  Sale Price  pursuant to this
Section 29 shall bear  interest  from the Closing Date to the date of payment at
the Agreed Interest Rate.  Buyer shall assist Seller in preparation of the final
statement  of the Sale Price  under  this  Section  29 by  furnishing  invoices,
receipts,  reasonable  access to personnel  and such other  assistance as may be
requested by Seller to facilitate such process post-Closing.
