                       OPERATIONS AND CASUALTY LOSS

     6.1 Operations.  Between the Effective Date and Closing, as to the portion
of the Assets to be conveyed which each of the respective Sellers now operates,
they shall operate the same in a good and workmanlike manner and as would be
operated by a reasonably prudent operator and in accordance with recent past
practices.  As of  the Closing Date, such operations shall be turned over to
and become the  responsibility of Buyers, unless an applicable unit, pooling,
communitization or operating agreement requires that any Seller, other than
Santa Barbara Partners or Hallador Production, continue to operate such
Assets, in which case (unless Buyers and Sellers otherwise agree) such
Seller shall continue to be obligated to operate such portion of the
Assets, pursuant to and under the terms of such applicable agreement, until
such time after Closing as such applicable agreement is assigned or any
necessary consents to Buyers physically operating the Assets
are obtained, or such agreement otherwise requires.  As of and after the
Closing, Buyers, including after Closing Santa Barbara Partners and Hallador
Production, shall physically operate any such Assets which any such Seller
continues to be obligated to operate on behalf of such Seller, and shall
indemnify and hold such Seller harmless from any damages or losses incurred
by such Seller resulting from Buyers', Santa Barbara Partners' or Hallador
Production's operations of such Assets.  Notwithstanding anything to the
contrary in the foregoing, for periods after the Effective Date, Sellers
shall have no liability as operator to Buyers, for any operations by Sellers
under this Section 6.1, for loss or damages sustained, or liabilities
incurred, except as may result solely or directly from, and in no event shall
Buyers have any liability to Sellers resulting from, Sellers' gross
negligence or willful misconduct.

     6.2 Casualty Loss.  The risk of Casualty Loss relating to the Assets,
and the property of Santa Barbara Partners and Hallador Production shall be
borne by Sellers until the Closing Date, and Sellers shall retain all risk of
any change in the condition of the Assets, or the property of Santa Barbara
Partners and Hallador Production caused by a Casualty Loss from the Execution
Date until the Closing Date.  In the event of any such change in condition of
the Assets, or the property of Santa Barbara Partners and Hallador Production

elect not to restore the changed Assets or property, such Assets or property
either, as is determined in the sole discretion of the Buyers: (i) shall be
deleted from this Agreement and the Purchase Price shall be adjusted in an
amount as is reasonably determined by Buyer to be the value of the changed
Assets or property; or (ii) shall continue to be included in this Agreement
and the insurance proceeds related to such Casualty Loss delivered to Buyers.

     6.3 Successor Operator.  Except to the extent that Hallador Production or
Santa Barbara Partners are the current operator of the Assets and remain
operator despite Buyers' acquisition of the Stock and the Trio Partnership
Interests, Buyers acknowledge and agree that Sellers cannot and do not
covenant or warrant that Buyers shall become successor operator of all or
any portion of the Assets, since the Assets or portions thereof may be
subject to unit, pooling, communitization, operating or other agreements
which control the appointment of a successor operator.

          6.4.4 Kirschenmann. With regard to Hallador LLP employee

Sellers have agreed upon a payment to Sellers in the amount equal to six (6)
months of Kirschenmann's Base Pay as an increase in Purchase Price payable at
Closing pursuant to Section 3.2.2, in order to partially offset certain costs of
Sellers associated with the termination of such employee (the "Kirschenmann
Adjustment").  E&B, or an Affiliate of E&B, shall deliver the Kirschenmann
Adjustment, in exchange for delivery by Hallador LLP to E&B of a written
agreement in a form reasonably acceptable to E&B providing for the agreement

may make all disclosures which are required or prudent under applicable laws
or Legal Requirements, including, but not limited to, rules, regulations and
guidelines of the Securities and Exchange Commission and applicable stock
exchanges.

     11.11  Termination of Guarantees and Other Commitments.
          11.11.1  Subject to applicable laws, as of the Closing Date, all of
the following shall be canceled or terminated: (i) undertakings, comfort

connection with the Assets, Santa Barbara Partners or Hallador Production;
and (ii) letters of credit, surety bonds, and related indemnity agreements
arranged and maintained by Sellers or any of its Affiliates with respect to
the Assets, Santa Barbara Partners or Hallador Production.

          11.11.2  Buyers understand and agree that all insurance policies,
provided to or for the Assets, Santa Barbara Partners and Hallador Production

Sellers will be terminated with regard to the Assets, Santa Barbara Partners
and Hallador Production as of the Closing.

          11.11.3  Sellers and Sellers' Affiliates shall have no
responsibility or liability under this Agreement to provide for insurance
coverage or any such security for the Assets, Santa Barbara Partners or
Hallador Production in any manner whatsoever after the date this Agreement is
executed by Buyers and Sellers, except to the extent that such insurance is
provided on a "claims made" policy, in which case, the Sellers and/or
Sellers' Affiliates shall, if necessary to continue the availability of such
coverage for occurrences prior to the Effective Date, procure a tail policy
in order to effectuate an "occurrence" policy related to any insurable claims
for the period of ownership of the Assets.

          11.11.4  E&B agrees that for the period of time from the Closing
Date until the payment of all amounts due under the Notes, that E&B will

Sudden and Accidental Pollution coverage with a Five Million Dollar
($5,000,000.00) combined single limit, with a deductible no greater than One
Hundred Thousand Dollars ($100,000.00). Any combination of primary and excess
insurance is allowed as long as the total limit requirement is satisfied.

     11.12  Like Kind Exchange.  Sellers agree to cooperate with Buyers for
Buyers to try to effect a tax deferred exchange under Internal Revenue Code
Section 1031, including, but not limited to, the introduction into the
transaction contemplated hereby of a third party intermediary to accomplish
such result (a "Tax Deferred Exchange Election"), provided, however, that
(a) Sellers shall not incur any additional liability or financial obligations
as a consequence of such exchange, (b) such exchange shall not delay the date
of Closing, and (c) no Party shall be required to take title to any property
as part of an exchange other than Buyers receiving title to the subject
property herein.  This Agreement is not subject to or contingent upon any
Party's ability to effectuate a tax deferred exchange.  In the event any
exchange contemplated by a Party should fail to occur, for whatever reason,
the sale of the Assets, the Stock and the Trio Partnership Interest shall
nonetheless be consummated as provided herein.

     11.13  Access to Geologic and Geophysical Information.  As long as the
same remains in Buyers' possession or control, Sellers retain the right to
copy any and all geologic and geophysical information transferred to Buyers
hereunder, and Buyers shall grant Sellers access to all such information and
agree to co-operate with Sellers in obtaining access to such information no
longer in Buyers' possession or control.

     11.14  Restrictions on Operations.  Except as otherwise contemplated in
this Agreement or in the event of an emergency, in which case Sellers shall
immediately notify Buyers of the action required to be taken as a result of
such emergency and involve Buyers in such decision making as soon as
practical, Sellers shall, without the express written consent of Buyers,
(i) between the Execution Date and the Closing Date incur no liability or
enter into any commitments exceeding $50,000 with respect to the Assets,
Santa Barbara Partners or Hallador Production, except in the ordinary course
of business consistent with past practice and in compliance with the
operating requirements of Section 6.1, (ii) between the Effective Date and
the Closing Date not release, sell, transfer, make any disposition of,
abandon or relinquish any right, title or interest in the Assets, Santa
Barbara Partners or Hallador Production, or in personal property related to
the Assets, Santa Barbara Partners or Hallador Production, except in the
ordinary course of business consistent with past practice, (iii) between the
Execution Date and the Closing Date not cancel any contract associated with
the Assets, Santa Barbara Partners or Hallador Production except in the
ordinary course of business consistent with past practice, and (iv) between
the Effective Date and the Closing Date not enter into any hedging, forward
sales or similar agreements with respect to production from the Assets, Santa
Barbara Partners or Hallador Production.  No later than ten (10) days after
the Execution Date, Sellers shall disclose in writing to Buyers all contracts
entered into, liabilities incurred and commitments made with a value in
excess of Fifty Thousand Dollars ($50,000) by Santa Barbara Partners,
Hallador Production or associated with the Assets, other than contracts,
liabilities and commitments for customary oil and gas field operations and
maintenance, between the Effective Date and the Execution Date.

     11.15  Exhibits and Schedules.  Sellers will, from time to time prior to
September 10, 2004, promptly supplement or amend the Exhibits or Schedules to
this Agreement with respect to any matter arising or determined after the
date of this Agreement, which, if existing or known as of the Execution Date,
would have been required to be set forth or described in such Exhibits or
Schedules in order to make any representation or warranty set forth in this
Agreement true and correct as of such date, subject to Buyers' approval, such
approval not to be unreasonably withheld or delayed.  Any such amended or
supplemented Schedules or Exhibits shall qualify the representations and
warranties contained in this Agreement as though provided at the Execution
Date.

                                 SECTION 12
                                    TAXES

     12.1  Apportionment of Taxes.  All ad valorem taxes, real property
taxes, personal property taxes and similar obligations shall be apportioned
as of the Effective Date between Buyers and Sellers.  All such taxes
allocable to the periods before the Effective Date shall be paid by Sellers,
and all such taxes allocable to the Effective Date and after shall be paid by
Buyers.  Any refunds of taxes allocable to periods prior to the Effective
Date shall be the property of Sellers and shall be promptly paid to it.
Buyers shall file or cause to be filed all required reports and returns
incident to such taxes which are due on or after the Closing Date, and shall
pay or cause to be paid to the taxing authorities all such taxes reflected on
such reports and returns.

     12.2  Sales Taxes, Filing Fees, Etc.  The Purchase Price provided for
hereunder is net of any sales taxes or other transfer taxes.  Buyers shall be
liable for any sales tax or other transfer tax as well as any applicable
conveyance, transfer and recording fees, and real estate transfer stamp or
taxes imposed upon the sale pursuant to this Agreement, and Buyers shall
defend any action by a governmental agency to collect such taxes or fees, and
will hold Sellers harmless from any cost or liability for taxes, fees,
penalty, interest or costs, including reasonable attorney's fees, assessed as
a result of this transaction.

     12.3  Other Taxes.  All production, severance or excise taxes,
conservation fees, permit fees, assessments and other similar such taxes or
fees (other than income taxes) relating to the Assets and/or oil and gas
produced and sold from the Assets prior to the Effective Date shall be paid
by Sellers, and all such taxes and fees relating to such oil and gas produced
and sold on the Effective Date and after shall be paid or reimbursed by
Buyers.  In the event such taxes attributable to the Assets are not assessed
on a current year basis, it is agreed that when such taxes are assessed,
insofar as they accrued to the Assets on or before the Effective Date, they
shall be paid by Sellers upon receipt of a statement and supporting
documentation.

     12.4  Cooperation on Tax Matters.
     Buyers shall be responsible for filing of federal and state income Tax
Returns for Hallador Production and Santa Barbara Partners for the period
from the Closing Date until the end of the tax year 2004, and Sellers shall
be responsible for filing the federal and state income Tax Returns for
Hallador Production (individually or on a consolidated basis with Affiliates)
and Santa Barbara Partners for the period from January 1, 2004 until the
Closing Date.  In the event Sellers and Buyers determine that Santa Barbara
Partners should file federal and state income Tax Returns only for the year
ended December 31, 2004, Sellers and Buyers shall cooperate to prepare and
file such returns, with Sellers responsible for payment of federal and state
income taxes attributable to the period ending on the Closing Date, and
Buyers responsible for payment of all such taxes attributable to the period
beginning on the day after the Closing Date.  Sellers shall provide to Buyers
executed and filed copies of the Hallador Production Tax Returns (as is
returns) and Santa Barbara Tax Returns for the past seven (7) years within
fifteen (15) days of the Execution Date, as well as a detail of all payments
made prior to such date with regard to 2004 federal and state income Taxes.
The Buyers and the Sellers shall cooperate fully, as and to the extent
reasonably requested by the other Party, in connection with the filing of Tax
Returns related to Hallador Production and Santa Barbara Partners and any
audit, litigation or other proceeding and making employees available on a
mutually convenient basis to provide additional information and explanation
of any material provided hereunder.  The Buyers and the Sellers shall
(i) retain all books and records with respect to Tax matters pertinent to
Hallador Production and Santa Barbara Partners relating to any whole or
partial Taxable period beginning before the Closing Date until the expiration
of the statute of limitations (and, to the extent notified by the Buyers or
any Sellers, any extensions thereof) of the respective Taxable periods, and
to abide by all record retention agreements entered into with any Taxing
authority, and (ii) give the other Party reasonable written notice prior to
transferring, destroying or discarding any such books and records and, if the
other Party so requests, the Buyers or Sellers, as the case may be, shall
allow the other Party to take possession of such books and records.

     The Buyers and the Sellers further agree, upon request, to use their
best efforts to obtain any certificate or other document from any
Governmental Authority or any other Person as may be necessary to mitigate,
reduce or eliminate any Tax that could be imposed (including, but not limited
to, with respect to the transactions contemplated hereby).

     12.5  Confidentiality.  Any information shared in connection with Taxes
shall be kept confidential, except as may otherwise be necessary in
connection with the filing of Tax Returns or reports, refund claims, Tax
audits, Tax claims and Tax litigation, or as required by Law.

     12.6  Audits.  The Sellers and the Buyers shall provide prompt written
notice to the other of any pending or threatened Tax audit, assessment or
proceeding that it becomes aware of related to Hallador Production or Santa
Barbara Partners for whole or partial periods for which it may be indemnified
by the other Party hereunder.  Such notice shall contain factual information
(to the extent known) describing the asserted Tax liability in reasonable
detail and shall be accompanied by copies of any notice or other document
received from or with any Tax authority in respect of any such matters.  If
an Indemnified Party has knowledge of an asserted Tax liability with respect
to a matter for which it may be indemnified hereunder and such party fails to
give the Indemnifying Party prompt notice of such asserted Tax liability,
then (a) if the Indemnifying Party is precluded by the failure to give prompt
notice from contesting the asserted Tax liability in any forum, the
Indemnifying Party shall have no obligation to indemnify the Indemnified
Party for any Taxes arising out of such asserted Tax liability, and (b) if
the Indemnifying Party is not so precluded from contesting, but such failure
to give prompt notice results in a detriment to the Indemnifying Party, then
any amount which the Indemnifying Party is otherwise required to pay the
Indemnified Party pursuant to Section 16 shall be reduced by the amount of
such detriment, provided, the Indemnified Party shall nevertheless be
entitled to full indemnification hereunder to the extent, and only to the
extent, that such party can establish that the Indemnifying Party was not
prejudiced by such failure.

     12.7  Control of Proceedings.  The Party responsible for the Tax under
this Agreement shall control audits and disputes related to such Taxes
(including action taken to pay, compromise or settle such Taxes).  Reasonable
out of pocket expenses with respect to such contests shall be borne by the
Sellers and the Buyers in proportion to their responsibility for such Taxes
as set forth in this Agreement.  Except as otherwise provided by this
Agreement, the non-controlling party shall be afforded a reasonable
opportunity to participate in such proceedings at its own expense.

     12.8  Closing Tax Certificate.  At the Closing, each of the Sellers
shall deliver to the Buyers a certificate signed under penalties of perjury
(i) stating that it is not a foreign corporation, foreign partnership,
foreign trust or foreign estate, (ii) providing its U.S. Employer
Identification Number and (iii) providing its address, all pursuant to
Section 1445 of the Internal Revenue Code.  At the Closing, the Buyers shall
deliver to the Sellers a statement providing its U.S. Employer Identification
Number and its address.

                                   SECTION 13
                                  TERMINATION

     13.1  Termination.  This Agreement and the transaction contemplated
herein may be terminated at any time prior to Closing:

          13.1.1  by mutual consent of the Parties;

          13.1.2  by any of the Sellers, without impairing any other rights
hereunder, if there has been a material breach of covenant or agreement
contained in this Agreement on the part of any of the Buyers (including,
without limitation, Buyers' failure to make the payment specified in either
Section 3.2.1 and 3.2.2), or a failure of a condition and such breach of a
covenant or agreement or failure of a condition has not been cured within 10
business days of receipt of notice of same, unless such breach or failure is
not, by its nature, curable within such period and then and in that event
such breach or failure has not been cured within a reasonable time following
receipt of notice of same;

          13.1.3  by any of the Buyers, without impairing any other rights
hereunder, if there has been a material breach of covenant or agreement
contained in this Agreement on the part of any of the Sellers, or a failure
of a condition and such breach of a covenant or agreement or failure of a
condition has not been cured within 10 business days of receipt of notice of
same, unless such breach or failure is not, by its nature, curable within
such period and then and in that event such breach or failure has not been
cured within a reasonable time following receipt of notice of same;

          13.1.4  by any of the Buyers or Sellers, upon written notice to the
other Parties on or prior to September 10, 2004, that one of the following
has occurred: (a) a Material Deficiency; and/or (b) Title Defect(s) in the
aggregate in excess of $200,000.00;

          13.1.5  by any of the Buyers or Sellers upon litigation or
administrative proceeding pending (or threatened), or an investigation
commenced (and pending), by any third party seeking to restrain or prohibit
(or questioning the validity or legality of) the consummation of the
transactions contemplated by this Agreement or seeking damages in connection
therewith which makes it unreasonable to proceed with the consummation of the
transactions contemplated hereby;

          13.1.6  by any of the Buyers upon written notice to the other
Parties that any event that is under Sellers' control, excluding fluctuations
in natural oil and gas production and prices, has occurred after September
10, 2004 that affects Santa Barbara Partners, Hallador Production or the
Assets and that would significantly impair Buyers' ability to obtain
financing, and that Sellers fail to cure within 30 days of receipt of notice
of same, unless such breach or failure is not, by its nature, curable within
such period and then and in that event such breach or failure has not been
cured within a reasonable time following receipt of notice of same; or

          13.1.7  by any of the Buyers upon written notice to the other
Parties after September 10, 2004, that a Material Deficiency has occurred.

     13.2  Effect of Termination.

          13.2.1  In the event of termination of this Agreement by either
Party as provided in Section 13.1.1, this Agreement shall forthwith become
void and there shall be no liability or obligation on the part of any Party
or their respective affiliates, officers or directors or partners or
shareholders except as otherwise set forth herein.  Sellers shall in such
event return any part of the Down Payment paid as of such date within fifteen
(15) business days of such termination.

          13.2.2  In the event of termination of this Agreement by Buyers
pursuant to Sections 13.1.4. 13.1.5 or 13.1.6, Sellers shall return, within
fifteen (15) business days of such termination, the Down Payment less the
Non-Refundable Portion of the Down Payment.

          13.2.3  In the event this Agreement is terminated for any reason
other than as provided in Sections 13.2.1 or 13.2.2, Sellers shall retain all
of the Down Payment.

     13.3  Sole Remedy.  If the Agreement is terminated and all or any
portion of the Down Payment is retained, then Sellers agree that their sole
remedy, in consideration of holding the Assets, Santa Barbara Partners and
Hallador Production off the market and refraining from dealing with others
concerning the Assets, Santa Barbara Partners and Hallador Production and as
liquidated damages in lieu of all other damages, shall be their retention of
the Down Payment made by Buyers.  The Parties hereby acknowledge that the
extent of damages to Sellers occasioned by such breach or default or failure
to proceed by Buyers would be impossible or extremely impractical to
ascertain and that the Down Payment is a fair and reasonable estimate of such
damages under the circumstances.

                                   SECTION 14
                                 MISCELLANEOUS

and remedies hereunder.

          14.2.3  Subject to Section 14.2.1 the rights, benefits, duties and
obligations of each Party hereto shall inure to the benefit of, and be

and assigns (including after the Closing, Santa Barbara Partners and Hallador
Production as Affiliates of E&B), harmless against any and all damages,
claims, losses, liabilities and expenses, including, without limitation,

but not limited to any claims from current or former employees or contractors

the business of Santa Barbara Partners, Hallador Production or the ownership
of the Acquired Assets prior to the Effective Date.

          15.3.2  Each of the Trio Sellers shall, jointly and severally,
indemnify and hold harmless each of Buyers (including after the Closing,
Santa Barbara Partners and Hallador Production as Affiliates of E&B), and

arising out of any third party claim, legal suit or proceeding against

arises from ownership of the Trio Partnership Interests or the ownership of

          15.3.3  Each of the Buyers shall, jointly and severally,

liabilities and expenses, including, without limitation, reasonable legal,

the conduct of the business of Buyers or their respective subsidiaries or the
ownership of the properties owned or leased by Buyers or their respective
subsidiaries on or after the Effective Date.

          15.3.4  Notwithstanding anything to the contrary herein, any
indemnification obligations of the Parties and all claims for indemnification
arising from, regarding or related to Environmental Liabilities shall be
governed by the provisions of Section 5 and no Party shall be entitled to
indemnification or shall make any claim for indemnification arising from,
regarding or related to Environmental Liabilities under this Section 15.3.

          15.3.5  There are no third party beneficiaries to this Agreement.
Nothing in this Agreement, express or implied, is intended to confer upon any
Person, other than the Parties hereto and their respective successors, and
assigns, any benefit, right, remedy or obligation.

     15.4  Method of Asserting Claims.  The Party making a claim under
Section 5.3.3 or this Section 15 is hereinafter referred to as the
"Indemnified Party" and the Party against whom such claims are asserted is
hereinafter referred to as the "Indemnifying Party."  All claims by an
Indemnified Party under Section 5.3.3 or this Section 15 shall be asserted
and resolved as follows:

          15.4.1  If any claim or demand for which an Indemnifying Party
might be liable to an Indemnified Party hereunder is asserted against or
sought to be collected from such Indemnified Party by a third party, such
Indemnified Party shall as promptly as is practicable after its receipt of
such claim or demand notify in writing the Indemnifying Party of such claim
or demand, specifying the nature of and specific basis for such claim or
demand and the amount or the estimated amount thereof to the extent then
feasible (which estimate shall not be conclusive of the final amount of such
claim and demand) (a "Claim Notice").

     The Indemnifying Party may, and upon request of the Indemnified Party
shall, retain counsel, experts and other providers of its choice to represent
the Indemnifying Party in connection with and to defend the Indemnified Party
against such claim or demand and shall pay the reasonable and documented fees
and reimburse the reasonable and documented disbursements of the Indemnified
Party as well as those of its own, including its counsel, experts and
representatives with regard thereto; provided, however, that any Indemnified
Party is hereby authorized prior to the date on which it receives written
notice from the Indemnifying Party of its assumption of the defense of any
such claim, to retain counsel whose reasonable fees and expenses shall be at
the expense of the Indemnifying Party to file any action, answer or other
pleading and take such other action which it shall reasonably deem necessary
to protect its interests or those of the Indemnifying Party until the date on
which the Indemnified Party receives such notice from the Indemnifying Party.

     In the event that the Indemnifying Party shall retain counsel, the
Indemnified Party shall have the right to retain its own counsel but the fees
and expenses of such counsel shall be at the expense of the Indemnified Party
unless:
                                     (i)    the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such
counsel; or
                                     (ii)  the named parties to any such
proceeding (including, but not limited to, any impleaded parties) include
both the Indemnifying Party and the Indemnified Party and representation of
both Parties by the same counsel would involve such counsel in an actual or
potential conflict of interest in violation of applicable principles of
professional ethics.

          15.4.2  If requested by the Indemnifying Party, the Indemnified
Party agrees to cooperate with the Indemnifying Party and its counsel in
contesting any claim or demand that the Indemnifying Party defends, or, if
appropriate and related to the claim in question, in making any counterclaim
against the Person asserting the third party claim or demand, or any cross-
complaint against any Person.  If the Indemnifying Party has indicated in
writing that it will indemnify the Indemnified Party, no claim or demand that
would result in an Indemnifying Party being liable hereunder may be settled
without the consent of the Indemnifying Party which consent shall not be
unreasonably withheld.  Unless the Indemnifying Party shall have agreed in
writing that any and all damages to the Indemnified Party related to a claim
or demand are fully covered by the indemnities provided herein, no such claim
or demand may be settled without the consent of the Indemnified Party, which
consent will not be unreasonably withheld.  Except with respect to
settlements entered into without the Indemnified Party's consent pursuant to
the immediately preceding sentence, to the extent it shall be determined that
the Indemnified Party shall have no right to be indemnified by the
Indemnifying Party, the Indemnified Party shall promptly pay to the
Indemnifying Party:
                                   (i)   any amounts previously paid or
advanced by the Indemnifying Party to the Indemnified Party or third parties,
with respect to or in connection with such matters; plus
                                   (ii)  interest thereon until paid by the
Indemnified Party at the Interest Rate for the period commencing on the date
on which such amount was paid or advanced and ending sixty (60) days after
the date on which it was finally determined that the Indemnified Party had no
such right to be indemnified.

          15.4.3  In the event the Indemnified Party should have a
claim against the Indemnifying Party hereunder which does not involve a claim
or demand being asserted against or sought to be collected from it by a third
party, the Indemnified Party shall as promptly as is practical send a Claim
Notice with respect to such claim to the Indemnifying Party; provided,
however, that any failure to give such notice will not waive any rights of
the Indemnified Party except to the extent that either the rights of the
Indemnifying Party are actually prejudiced or such notice is not given within
the applicable time periods set forth in this Agreement.  If the Indemnifying
Party notifies in writing the Indemnified Party that it does not dispute such
claim, the amount of such claim shall be conclusively deemed a liability of
the Indemnifying Party hereunder and shall be paid to the Indemnified Party
immediately.  If the Indemnifying Party disputes such claim, such dispute
shall be resolved by good faith negotiations between the Parties.

          15.4.4  From and after the delivery of a Claim Notice hereunder, at
the reasonable request of the Indemnifying Party, the Indemnified Party shall
grant the Indemnifying Party and its representatives full and complete access
to the books, records and properties of the Indemnified Party to the extent
reasonably related to the matters with which the Claim Notice is concerned.
The Indemnifying Party will not, and shall require that its representatives
do not, use (except in connection with such Claim Notice) or disclose to any
third Person other than the Indemnifying Party's representatives (except as
may be required by applicable Legal Requirements) any information obtained
pursuant to this Section 15.4.4 that is designated as confidential by the
Indemnified Party, unless such information is:

                                   (i)   generally available to the public
other than as the result of a wrongful act or omission by the Indemnifying
Party;
                                   (ii)  already within the knowledge of the
Indemnifying Party;

                                   (iii)  available to the Indemnifying Party
through rights other than as provided in this Section 15.4.4, or

                                   (iv)  provided to the Indemnifying Party
in writing by a third party who is under no obligation to the Indemnified
Party to protect the confidentiality thereof.

     All such access shall be granted during normal business hours, shall be
subject to the normal safety regulations of the Indemnified Party, and shall
be granted under conditions that will not interfere with the business and
operations of the Indemnified Party.  Nothing contained in this
Section 15.4.4 shall be construed to expand or contract the rights or
obligations of the Indemnifying Party with respect to any information
previously provided to the Indemnifying Party pursuant to any other
confidentiality agreement.

     15.5  Right to Cure.  Any Party that is obligated to indemnify, defend
and/or hold harmless any other Party pursuant to any provision of this
Section 15 shall have the right to cure, within a reasonable time and in a
manner reasonably satisfactory to such Indemnified Party, any matter giving
rise to such obligation; provided, however, that any such cure shall not
relieve or reduce any such obligation to the extent that such cure is
inadequate.
