      2.05. Allocations and Adjustments. If Closing occurs:

            (a) Buyer will be entitled to all revenues, production, proceeds,
income, and products from or attributable to each Asset on and after the
relevant Effective Time, and will be responsible for (and entitled to any
refunds with respect to) all Property Costs attributable to the Assets and
incurred on and after the Effective Time. Seller will be entitled to all
revenues, production, proceeds, income, and products from or attributable to
each Asset prior to the Effective Time, and will be responsible for (and
entitled to any refunds with respect to) all Property Costs attributable to each
Asset and incurred prior to the Effective Time. "Property Costs" will mean all
amounts attributable to the operation and ownership of the Assets incurred and
paid in the Ordinary Course of Business. For purposes of allocating production,
products, accounts receivable and proceeds under this Section, (i) liquid
hydrocarbons will be deemed to be "from or attributable to" the Wells when they
pass through the pipeline connecting into the storage facilities into which they
are run and (ii) gaseous hydrocarbons will be deemed to be "from or attributable
to" Wells when they pass through the delivery point sales meters on the
pipelines through which they are transported. In order to accomplish the
foregoing allocation of production the parties will rely upon gauging, metering
and strapping procedures conducted by Seller on or about the Effective Time to
the extent possible and unless demonstrated to be inaccurate will utilize
reasonable interpolating procedures to arrive at an allocation of production
when exact gauging, metering and strapping data is not available on hand as of
the Effective Time. Seller will provide to Buyer evidence of all gauging,
metering and strapping procedures conducted hereunder in connection with the
Wells, together with all data necessary to support any estimated allocation, for
purposes of establishing the adjustment to the Purchase Price. Ad valorem taxes
for 2005 will be prorated on a daily basis, with Buyer liable for the portion
allocated to the period on and after the Effective Time and Seller liable for
the portion allocated to the period before the Effective Time. If the amount of
such taxes for part, or all, of the Assets is not available on the Closing Date,
proration of taxes shall be made on the basis of taxes assessed in the previous
year, with a subsequent cash adjustment of such proration to be made between
Seller and Buyer, when actual tax figures are available. The "Preliminary
Amount" will be the Purchase Price, adjusted as provided below, based upon the
best information available at time of Closing.

            (b) The Purchase Price will be, without duplication,

                  (i)   increased by the following amounts:

                        (A)   the aggregate amount of all non-reimbursed
                              Property Costs which are attributable to the
                              period from the Effective Time to the Closing Date
                              and which are incurred and paid by Seller with
                              respect to the Wells and Subject Leases;

                                        9

<PAGE>

                        (B)   an amount equal to the agreed value of all
                              Hydrocarbons in storage above the pipeline
                              connection at the Effective Time that is credited
                              to the Wells and which stored Hydrocarbons have
                              not been sold by Seller or for which Seller has
                              not been paid;

                        (C)   the amount of any upward adjustment pursuant to
                              Section 11.04;

                        (D)   any other upward adjustment mutually agreed upon
                              by the parties;

                  (ii)  decreased by the following amounts:

                        (A)   the aggregate amount of proceeds received by
                              Seller from the sale of Hydrocarbons produced from
                              and attributable to the Wells between the
                              Effective Time and the Closing Date;

                        (B)   the amount of any downward adjustment relating to
                              Title Defects as set forth in Article 11;

                        (C)   the amount of any adjustment relating to an
                              uninsured casualty as required by Section 11.09;

                        (D)   Seller' s share of estimated ad valorem taxes
                              through the Effective Time; and

                        (E)   the amount of any downward adjustment mutually
                              agreed upon by the parties.

            (c) Subject to the arbitration provisions of Article 12.14 as to
adjustments under Section 2.05(b)(ii)(b), as soon as practicable after Closing,
but no later than ninety (90) days following the Closing Date, Seller will
prepare and submit to Buyer, a statement (the "Final Settlement Statement")
setting forth each adjustment or payment which was not finally determined as of
the Closing Date and showing the values used to determine such adjustments to
reflect the final adjusted Purchase Price (the "Final Amount"). On or before
thirty (30) days after receipt of the Final Settlement Statement, Buyer will
deliver to Seller a written report containing any changes which Buyer proposes
be made to the Final Settlement Statement. Seller and Buyer shall undertake to
agree with respect to the amounts due pursuant to the post-closing adjustment no
later than one hundred fifty (150) days from the Closing Date. If Seller and
Buyer are unable to agree within one hundred fifty (150) days after the Closing
Date as to adjustment matters not subject to arbitration in accordance with this
Agreement, Seller will select an independent accounting firm in Corpus Christi,
Texas, from a list of three such firms provided by Buyer (none of which will be
the independent accounting firm regularly used by Buyer or Seller), which firm
will audit the Final Settlement Statement and determine the Purchase Price
adjustment or payment amount in accordance with the terms and conditions set
forth in this Agreement. The decision of such independent accounting firm will
be binding on Seller and Buyer, and the fees and expenses of such independent
accounting firm will be borne one-half by Seller and one-half by Buyer. The date
upon which such agreement is reached or upon which the Purchase Price is
otherwise established, as provided in the preceding sentence, will be called the
"Settlement Date." In the event that (a) the Final Amount is more than the
Preliminary Amount, Buyer will pay to Seller the amount of the difference; or
(b) the Final Amount is less than the Preliminary Amount, Seller will pay to
Buyer the amount of the difference. Such payment will be made within five (5)
business days of the Settlement Date via wire transfer to accounts specified by
Seller or Buyer as appropriate.

commercially reasonable efforts to assist Buyer in becoming the successor
operator of those properties operated by Seller at the Effective Time.

point, penalties, reservation fees, take information, connection terms,
redetermination provisions, quality specifications and processing provisions)
which Buyer would otherwise consider accepting for the purchase and sale of the
production. Manti, or its Affiliate, shall then have an optional prior right,
for a period often (10) days after receipt of the Offer Notice, to exercise its
right to purchase such production by matching the terms and conditions contained
in the Offer Notice. Failure to notify Buyer of its election within such ten
(10) day period will be deemed an election by Manti not to exercise its
preferential purchase right, solely with respect to the offer contained in such
Offer Notice. Notwithstanding the foregoing, to the extent the Hydrocarbon
production offered for sale is subsequently purchased by a third party on terms
and conditions that are materially different than those contained in the Offer
Notice, pursuant to which Manti, or its Affiliate, has elected, or is deemed to
have elected, not to purchase, Manti's preferential right to purchase will be
reinstated, with a shortened time period of five business days for exercise,
which will commence upon Manti's receipt of full details of the terms and
conditions under which such production is being sold.

or otherwise) with respect to any representation or warranty, or covenant or

claim specifying the factual basis of that claim in reasonable detail to the
extent then known by Buyer.

      10.5. Limitations on Amount--Seller. If the Closing occurs, Seller will
have no liability under Section 10.02 until the total of all Damages indemnified

no liability under Section 10.03 until the total of all Damages indemnified
thereunder exceeds $100,000, and then Buyer will be liable for the entire amount

      10.7. Procedure for Indemnification--Third Party Claims.

            (a)   Promptly after receipt by an indemnified party under Section
                  10.02 or 10.03 of a claim for Damages or notice of the
                  commencement of any Proceeding against it, such indemnified
                  party will, if a claim is to be made against an indemnifying
                  party under such Section, give notice to the indemnifying
                  party of the commencement of such claim.

            (b)   If any Proceeding referred to in Section 10.07(a) is brought
                  against an indemnified party and it gives notice to the
                  indemnifying party of the commencement of such Proceeding, the
                  indemnifying party will be entitled to participate in such
                  Proceeding and, to the extent that it wishes (unless (i) the
                  indemnifying party is also a party to such Proceeding and the
                  indemnified party determines in good faith that joint
                  representation would be inappropriate, or (ii) the
                  indemnifying party fails to provide reasonable assurance to
                  the indemnified party of its financial capacity to defend such
                  Proceeding and provide indemnification with respect to such
                  Proceeding), to assume the defense of such Proceeding with
                  counsel satisfactory to the indemnified party and, after
                  notice from the indemnifying party to the indemnified party of
                  its election to assume the defense of such Proceeding, the
                  indemnifying party will not, as long as it diligently conducts
                  such defense, be liable to the indemnified party under this
                  Article 10 for any fees of other counsel or any other expenses
                  with respect to the defense of such Proceeding, in each case
                  subsequently incurred by the indemnified party in connection
                  with the defense of such Proceeding. If the indemnifying party
                  assumes the defense of a Proceeding, no compromise or
                  settlement of such claims may be effected by the indemnifying
                  party without the indemnified party's consent unless (A) there
                  is no finding or admission of any violation of Legal
                  Requirements or any violation of the rights of any Person and
                  no effect on any other claims that may be made against the
                  indemnified party, and (B) the sole relief provided is
                  monetary damages that are paid in full by the indemnifying
                  party; and (C) the indemnified party will have no liability
                  with respect to any compromise or settlement of such claims
                  effected without its consent.

                                       24

<PAGE>

            (c)   Notwithstanding the foregoing, if an indemnified party
                  determines in good faith that there is a reasonable
                  probability that a Proceeding may adversely affect it or its
                  affiliates other than as a result of monetary damages for
                  which it would be entitled to indemnification under this
                  Agreement, the indemnified party may, by notice to the
                  indemnifying party, assume the exclusive right to defend,
                  compromise, or settle such Proceeding, but the indemnifying
                  party will not be bound by any determination of a Proceeding
                  so defended or any compromise or settlement effected without
                  its consent (which may not be unreasonably withheld).

      10.8. Procedure for Indemnification--Other Claims. A claim for
indemnification for any matter not involving a third-party claim may be asserted
by notice to the party from whom indemnification is sought.

      10.9. Extent of Representations and Warranties.

            (b)   Buyer acknowledges and affirms that it has had full access to
                  information with respect to the Assets, and that Buyer has
                  made its own independent investigation, analysis and
                  evaluation of the Contemplated Transactions (including Buyer's

party or of which they are a beneficiary, and (ii) the same constitute
interpretations made by Seller which they deem confidential or proprietary and
which relate to other properties owned by Seller; and (c) authorize Buyer and
its representatives to consult with attorneys, abstract companies and other
consultants or independent contractors of Seller, whether utilized in the past
or presently, concerning title-related matters with respect to the Assets.
Seller will advise Buyer of any restrictions or constraints on the right of
Seller to provide and disclose to Buyer all data and information herein
provided, and Buyer will have the right and power to attempt to remove such
restrictions and constraints.

      11.2. Defensible Title. On the Closing Date, each Seller will convey to
Buyer Defensible Title to such Seller's interest in the Assets. As used herein
the term "Defensible Title" will mean, as to such Seller's interest in the
Assets, that title which:

      Entitles Seller, as to the Wells described on Exhibit A to receive not
less than the interests set forth in such Exhibit as the respective "Net Revenue
Interests", of all Hydrocarbons produced, saved and marketed therefrom, through
the plugging, abandonment and salvage of such Wells, except for any decrease (i)
caused by orders of the appropriate regulatory body having jurisdiction over the
Wells that are promulgated after the Effective Time that concern pooling,
unitization, communization or spacing matters, (ii) caused by Buyer, its
successors or assigns; or (iii) arising from operation of any Contract
proportionately assigned to Buyer hereby.

                                       27

<PAGE>

      Obligates Seller, as to the Wells described on Exhibit A to bear not more
than the respective percentages designated as the "WorkinR Interests" set forth
in such Exhibits of the costs and expenses relating to the maintenance,
development and operation of the said Wells, through the plugging, abandonment
and salvage of such Wells, except for any increase (i) caused by Buyer, its
successors and assigns, (ii) that also results in the Net Revenue Interest
associated with the Well being proportionately increased, or (iii) caused by
orders of the appropriate regulatory agency having jurisdiction over the Wells
that are promulgated after the Effective Time that concern pooling, unitization,
communization or spacing matters;

      Constitutes all of Seller's right, title and interest in and to leasehold
estate and working interest in and to all of the Assets; and

      Is free and clear of all Encumbrances except for Permitted Encumbrances.

      11.3. Title Defects. On or before five (5) days before Closing, Buyer will
notify Seller in writing of any matter affecting the Assets which in the opinion
of Buyer would not give Buyer Defensible Title, in accordance with Section 11.02
hereof, and the Allocated Value of each such title defect (all of which are
herein called the "Title Defects"). Seller will thereupon have the right but not
the obligation to attempt to cure the Title Defects at their expense on or
before the Closing Date. If Seller elects not to cure the Title Defects or the
Title Defects cannot be cured or removed to the satisfaction of Buyer on or
before the Closing Date, Buyer may elect in writing (a) to waive the uncured
Title Defects or (b) to eliminate that portion of the Assets affected by the
Title Defects from the purchase and sale hereunder, in which event the Purchase
Price specified in Section 2.02 will be reduced by the Allocated Value of the
portion thereof so excluded; provided, however, that the Purchase Price will not
be adjusted pursuant to this Section 11.03(b) until the aggregate amount of the
value of the Title Defects exceeds $10.000 and then to the full extent of such
value. Any Title Defects which are not objected to by Buyer on or before five
(5) days before Closing will be deemed waived by the Buyer and to be Permitted
Encumbrances.

      11.4. Adjustments. If only a portion of any of the Assets is affected by
Title Defects, Buyer may elect to accept said Assets and pay a reduced Purchase
Price based upon the percentage loss of the affected Assets and the Purchase
Price will be adjusted by deducting the value of such Title Defect from the
Allocated Value of such Asset. If it is determined prior to Closing, by the
Seller or Buyer, that Seller's net revenue interest in any of the Wells is
greater than represented herein, the Wells will be increased by a proportionate
adjustment based upon the Allocated Value of such Producing Properties, taking
into account the relative increase in the expense bearing working interest, if
any, associated with the increased net revenue interest.

      11.5. Environmental Audit. Buyer may, at its option, cause an
environmental audit of the Assets to be conducted until five (5) days prior to
Closing ("Examination Period"). PROVIDED THAT, BUYER WILL REPAIR ANY DAMAGE TO
THE PROPERTIES OF SELLERS RESULTING FROM ITS INSPECTION OF SUCH PROPERTIES, AND
BUYER WILL INDEMNIFY, DEFEND (INCLUDING REASONABLE ATTORNEYS' FEES) AND HOLD
SELLERS HARMLESS FROM AND AGAINST ANY AND ALL LOSSES, COSTS, DAMAGES,
OBLIGATIONS, CLAIMS, LIABILITIES, EXPENSES OR CAUSES OF ACTION (COLLECTIVELY THE
"CLAIMS") ARISING FROM SUCH INSPECTIONS, INCLUDING WITHOUT LIMITATION CLAIMS FOR
PERSONAL INJURY, DEATH, PROPERTY DAMAGE AND LIENS FOR SERVICES PROVIDED, IN EACH
INSTANCE, EXCLUDING CLAIMS RESULTING FROM THE NEGLIGENCE OR STRICT LIABILITY OF
SELLERS OR THEIR RESPECTIVE OFFICERS, EMPLOYEES, AND AGENTS. Buyer will notify
Sellers in writing (the "Environmental Notice") on or before 5:00 p.m. (Central
Standard Time) not later than the end of the Examination Period of any
environmental matters disclosed by such audit or with respect to which Buyer
otherwise has knowledge, that Buyer reasonably believes in good faith may
constitute a Violation of Environmental Laws, including with such notice a
reasonably detailed description of the specific matter that is an alleged
Violation of Environmental Laws. Upon receipt of the Environmental Notice,
Seller will have the right, but not the obligation, to attempt to cure the
applicable environmental liabilities attributable to the Violations of
Environmental Laws prior to Closing. Seller's consideration of, or election to
proceed with, any of the remedies hereunder will not be deemed to be an
admission by any Person with respect to the occurrence of any Violation of
Environmental Law or any violation of any other Legal Requirement.

                                       28

      11.06. Remedies For Violations Of Environmental Laws. In the event that
any Violation of Environmental Law is not expressly waived by Buyer or cured by
Seller on or before the Closing, the following provisions will apply:

      (a)   If, in Buyer's reasonable good faith estimate, the aggregate amount
            to cure all Violations of Environmental Law described in the
            Environmental Notice (collectively, the "Defect Amount") is $100,000
            or less, Buyer will proceed to Closing in accordance with the
            remaining provisions hereby and such Violations of Environmental Law
            will be deemed waived.

      (b)   If, in Buyer's reasonable good faith estimate, the Defect Amount is
            more than $ 100,000 but less than five percent (5%) of the Purchase
            Price, Buyer will reduce the Purchase Price by an amount equal to
            the cost to cure the Violations of Environmental Law and proceed to
            Closing.

      (c)   If, in Buyer's reasonable good faith estimate, the Defect Amount is
            more than five percent (5%) of the Purchase Price, then either Buyer
            or Seller may elect to terminate this Agreement.

      11.7. Right of Termination. If the adjustments to the Purchase Price
pursuant to Sections 11.03, 11.04 and 11.06 exceed ten percent (10%) of the
Purchase Price, either party may terminate this Agreement by written notice to
the other prior to the Closing Date, in which case neither party will have any
liability to the other except as otherwise set forth in this Agreement.

      11.8. Disputes. If the parties are unable to agree as to (a) whether a
particular matter constitutes a Title Defect or Violation of Environmental Law;
(b) the portion of the Assets affected by the Title Defect or Defect Amount; or
(c) the appropriate reduction in the Purchase Price to be made upon elimination
from this transaction of the portion of the Assets affected by the Title Defect
or Defect Amount; then in those events if Closing occurs the average of Sellers'
and Buyer's estimate of the value of asserted Title Defects and Defect Amount
will be used to adjust the Purchase Price in accordance with Article 2 for
purposes of Closing, provided, that Sellers' and Buyer's estimate will be
consistent with the Allocated Values set forth on the Exhibits attached hereto.
It is further provided that, if the difference between Buyer's and Sellers'
estimates as to such amounts exceeds $200,000, Sellers may elect to terminate
this Agreement. If Closing occurs, such disagreement will be resolved after
Closing by arbitration in accordance with Section 12.14. In the event the values
of Title Defects and Defect Amount as estimated by Buyer are such that Buyer
believes it is entitled to refuse to close and Buyer elects to refuse to close,
such disagreement will be resolved by arbitration in accordance with Section
12.14.

      11.09. Casualty Loss and Condemnation.

            (a)   If after the date of execution of this Agreement and prior to
                  the Closing any part of the Assets is destroyed by fire or
                  other casualty or if any part of the Assets is taken in
                  condemnation or under the right of eminent domain or if
                  proceedings for such purposes are pending or Threatened, this
                  Agreement will remain in full force and effect notwithstanding
                  any such destruction, taking, proceeding, or threat.

            (b)   Except to the extent permitted or required pursuant to this
                  Agreement, after the date of execution of this Agreement,
                  without Buyer's prior consent, no insurance or condemnation
                  proceeds will be committed or applied by Seller prior to the
                  Closing Date to repair, restore, or replace a damaged or taken
                  portion of the Assets if the cost to repair, restore, or
                  replace a damaged or taken portion of the Assets is projected
                  to exceed $25,000. To the extent such proceeds are not
                  committed or applied by Seller prior to the Closing Date in
                  accordance with this Section 11.07(b), Seller will at the
                  Closing pay to Buyer all sums paid to Seller by reason of such
                  destruction or taking, less any reasonable costs and expenses
                  incurred by Seller in collecting such proceeds. In addition
                  and to the extent such proceeds have not been committed or
                  applied by Seller in accordance with this Section 11.07(b), in
                  such repair, restoration, or replacement, Seller will transfer
                  to Buyer, at Closing, without recourse against Seller, all of
                  the right, title, and interest of Seller in and to any unpaid
                  insurance or condemnation proceeds arising out of such
                  destruction or taking, less any reasonable costs and expenses
                  incurred by Seller in collecting such proceeds. Any such funds
                  which have been committed by Seller for repair, restoration,
                  or replacement as aforesaid will be paid by Seller for such
                  purposes or, at Seller's option, delivered to Buyer upon
                  Seller's receipt from Buyer of adequate assurance and
                  indemnity that Seller will incur no liability or expense as a
                  result of such commitment.

                                       30

            (c)   If and to the extent a casualty occurring after the date of
                  execution of this Agreement and before Closing is not covered
                  by insurance, Buyer and Seller will attempt to agree on the
                  value of the uninsured casualty on or before the date five (5)
                  days after Buyer receives written notice of the casualty. If
                  the parties are not able to agree on such value within such
                  5-day period, the value will be determined by an independent
                  casualty adjuster, experienced in determining casualty losses
                  in matters similar to the disputed casualty loss, who will be
                  selected by Seller from a list of three (3) such independent
                  casualty adjusters that is provided to Seller by the Buyer.
                  Said independent casualty adjuster will be selected by Seller
                  within five (5) days of the written receipt by Seller of
                  Buyer's written listing of independent casualty adjusters and
                  will provide both Seller and Buyer with a complete and
                  documented report as to his findings within ten (10) business
                  days of being selected by Seller.

      For purposes of this Section, the value of the uninsured casualty will be
equal to the lesser of (i) the aggregate reduction in Allocated Value of the
affected portion of the Assets resulting from the uninsured casualty, or (ii)
the amount required to repair the affected portion of the Assets to its
condition immediately preceding the occurrence of the casualty. The Purchase
Price will be reduced by the amount of the value of such an uninsured casualty
as finally determined pursuant to this Section, and if such final determination
is not available on the scheduled Closing Date, Closing will not be delayed, but
rather, such Purchase Price reduction will be a part of the final adjustments to
be made after Closing as contemplated by Section 2.05.

Act. Buyer's rights and remedies with respect to this transaction and with

COMM Ann. Section 17.41 et seq. (the "DTP A"), or any similar statute of any
jurisdiction that may be applicable to the transactions contemplated hereby.
Buyer hereby unconditionally waives the applicability of the DTPA, or any
similar statute, to this transaction and any and all rights, duties, or remedies
that might be imposed by the DTPA, or any similar statute, provided, however,
Buyer does not waive Section 17.555 of the DTPA. Buyer represents, warrants, and
acknowledges that it is purchasing the Assets for commercial or business use.
Buyer further acknowledges, represents, and warrants that Buyer has knowledge
and experience in financial and business matters that enables it to evaluate the
merits and the risks of a transaction such as this and that Buyer is not in a
significantly disparate bargaining position with Seller. Buyer expressly
acknowledges and recognizes that the price for which Seller has agreed to sell
the Assets and perform its obligations under the terms of this Agreement has
been predicated upon the inapplicability of the DTPA, or any similar statute,
and this waiver of the DTPA, and any similar statute, by the Buyer. BUYER
FURTHER RECOGNIZES THAT SELLER, IN DETERMINING TO PROCEED WITH ENTERING INTO
THIS AGREEMENT, HAS EXPRESSLY RELIED ON THE PRO VISIONS OF THIS SECTION 12.13.

      12.14. Arbitration. All disputes, controversies, or claims that may arise
among the parties relating to this Agreement will be submitted to, and
determined by, binding arbitration. The arbitration will be conducted before a
single arbitrator pursuant to the Commercial Arbitration Rules then in effect of
the American Arbitration Association. The arbitrator will apply the laws of the
State of Texas (without regard to conflict of law rules) to the dispute,
controversy, or claim. Evidentiary questions will be governed by the Texas Rules
of Evidence. The arbitrator's award will be in writing and shall set forth
findings and conclusions upon which the arbitrator based the award. The
prevailing party in the arbitration will be entitled to recover its reasonable
attorneys' fees, costs, and expenses incurred in connection with the
arbitration, as determined by the arbitrator. Any award pursuant to the
arbitration will be final and binding upon the parties and judgment on the award
may be entered in any federal or state court having jurisdiction. The provisions
of this Section will survive the termination of this Agreement. Notwithstanding
the foregoing, this Section will not prevent any party from seeking injunctive
relief from a court of competent jurisdiction under appropriate circumstances,
provided, however, such action will not constitute a waiver of the provisions of
this Section.

      12.15. Tax Deferred Exchange. If Seller so requests, Buyer agrees to
cooperate with Seller in a tax-deferred exchange described in Section 1031 of
the Internal Revenue Code of 1986, as amended. Notwithstanding the foregoing,
Buyer shall not be obligated to enter into any agreement or to consent to an
assignment of Seller's rights or obligations hereunder which may have the effect
of (i) impairing the title to the Assets, (ii) increasing Buyer's obligations or
liability hereunder or resulting in any additional cost, expense or liability to
Buyer; or (iii) requiring Buyer to execute a purchase agreement for the purchase
of the exchange property or to take record title to the exchange property.
Seller hereby agrees to indemnify, defend and hold Buyer harmless from and
against any and all costs, expenses, claims, damages, losses or liabilities
(including, without limitation, reasonable attorney fees and costs) incurred by
Buyer in connection with any exchange transaction or transactions or the
performance by Buyer of its obligations pursuant to this Section.

      12.16. Press Release. Except as may be required by applicable law, neither
Buyer nor Seller will issue at or prior to Closing any publicity or other press
release without the prior written consent of the other party. After Closing of
the Contemplated Transactions, it is agreed that Buyer will issue any and all
such releases, and Seller will not do so without Buyer's prior written consent.

      IN WITNESS WHEREOF, the parties have executed and delivered this Agreement
