not, and the consummation of the transactions contemplated hereby will not (i)
conflict with, or result in any violation or breach of any provisions of its
articles of incorporation or bylaws, (ii) result in any violation or breach of,

entity.

behalf of the Purchaser pursuant to this Agreement, to be true and correct as of
the date made;




Page 15 of

(iii) any
and all losses, liabilities, obligations, damages, costs and expenses based
upon, attributable to or resulting from the breach of any covenant or other
agreement on the part of Sellers under this Agreement;




(iv) all
losses, liabilities, obligations, damages, costs and expenses with respect to
which indemnification is provided hereunder (collectively, “Losses”) and any and
all notices, actions, suits, proceedings, claims, demands, assessments,
judgments, costs, penalties and expenses, including attorneys’ and other
professionals’ fees and disbursements (collectively, “Expenses”) incident
thereto; and




(v) any
taxes (including interest and penalties) assessed against Purchaser, Petro 2000,
or PetroGreen which arose prior to the Closing Date;




(b)
Purchaser hereby agrees to indemnify and hold Sellers and its affiliates,
agents, successors and assigns (collectively, the “Sellers’ Indemnified
Parties”) harmless from and against:




(i) any
and all Losses based upon, attributable to or resulting from the breach of any
covenant or other agreement on the part of Purchaser under this
Agreement;




(ii) any
and all payments of debts, claims and liabilities incurred by Petro 2000, Petro
Green, or Purchaser which are incurred subsequent to the Closing and which are
attributable to Purchaser’s operation of the business; and




(iii) all
Losses and any Expense incident thereto involving items listed in 10.1(b)(i) or
(ii).







10.2
Indemnification
Procedures.




(a) In
the event that any legal proceedings shall be instituted or that any claim or
demand (“Claim”) shall be asserted by any person in respect of which payment may
be sought under Section 10.1 hereof, the indemnified party shall reasonably and
promptly cause written notice of the assertion of any Claim of which it has
knowledge which is covered by this indemnity to be forwarded to the indemnifying
party.




(b) The
indemnifying party shall have the right, at its sole option and expense, to be
represented by counsel of its choice and to defend against, negotiate, settle or
otherwise deal with any Claim which relates to any Losses indemnified against
hereunder. If the indemnifying party elects to defend against, negotiate, settle
or otherwise deal with any Claim which relates to any Losses indemnified against
hereunder, it shall within five (5) days (or sooner, if the nature of the Claim
so requires) notify the indemnified party of its intent to do so.




Page 16 of
29


(c) If
the indemnifying party elects not to defend against, negotiate, settle or
otherwise deal with any Claim which relates to any Losses indemnified against
hereunder, and fails to notify the indemnified party of its election as herein
provided or contests its obligation to indemnify the indemnified party for such
Losses under this Agreement, the indemnified party may defend against,
negotiate, settle or otherwise deal with such Claim.  If the
indemnified party defends any Claim, then the indemnifying party shall reimburse
the indemnified party for the Expenses of defending such Claim upon submission
of periodic bills.  If the indemnifying party shall assume the defense
of any Claim, the indemnified party may participate, at his or its own expense,
in the defense of such Claim; provided, however, that such indemnified party
shall be entitled to participate in any such defense with separate counsel at
the expense of the indemnifying party if, (i) so requested by the indemnifying
party to participate or (ii) in the reasonable opinion of counsel to the
indemnified party, a conflict or potential conflict exists between the
indemnified party and the indemnifying party that would make such separate
representation advisable; and provided, further, that the indemnifying party
shall not be required to pay for more than one such counsel for all indemnified
parties in connection with any Claim.  The parties hereto agree to
cooperate fully with each other in connection with the defense, negotiation or
settlement of any such Claim.




(d) After
any final judgment or award shall have been rendered by a court, arbitration
board or administrative agency of competent jurisdiction and the expiration of
the time in which to appeal therefrom, or a settlement shall have been
consummated, or the indemnified party and the indemnifying party shall have
arrived at a mutually binding agreement with respect to a Claim hereunder, the
indemnified party shall forward to the indemnifying party notice of any sums due
and owing by the indemnifying party pursuant to this Agreement with respect to
such matter and the indemnifying party shall be required to pay all of the sums
so due and owing to the indemnified party by wire transfer of immediately
available funds within 10 business days after the date of such
notice.




(e) The
failure of the indemnified party to give reasonably prompt notice of any Claim
shall not release, waive or otherwise affect the indemnifying party’s
obligations with respect thereto except to the extent that the indemnifying
party can demonstrate actual loss and prejudice as a result of such
failure.




10.3
Reliance. No
disclosure by any party to this Agreement nor any investigation made by or in
behalf of any party with respect to another party shall be deemed to affect the
party’s reliance on the respective representations and warranties contained in
this Agreement and shall not effect a waiver of that party’s rights to indemnity
as herein provided or the breach of any said representations and
warranties.

RELATED
PARTY TRANSACTIONS








1.
            Notes
      receivable from John, Joseph, George and Alfred Schwartz (listed on
      Exhibit F). Loans were made by these investors to Petro 2000 Exploration.
      This was prior to their investment in Petrogreen Energy,
      LLC.  The loan was for operating capital and the purchase of
      working interest.





2.
            Petro
      2000 sold a drilling rig and equipment to Petrogreen LLC.  The
      proceeds were used to pay off a payable owed by Petro 2000 to Petrogreen
      and the remainder was set up as a note payable from Petrogreen to Petro
      2000.  (Note listed on Exhibit
F)





3.
            Alejandro
      Perales transferred in to Petrogreen Energy 50% of his working interest in
      the Felix Brandt leases as a capital contribution.  He then sold
      the remaining 50% working interest to Petrogreen
      energy.  Petrogreen Energy set up a note payable to Alejandro
      Perales for the value of the 50% working interest
    transferred.
