other instrument to or by which such Member is a party or is bound or to which
any of the properties or assets of such Member are subject, or any Legal
Requirement (as defined herein) to which such Member is subject, or result in

      2.6 Acquisition of Chiste's Preferred Shares for Investment.

            (a) Each Member is acquiring Chiste's Preferred Shares for
investment for Member's own account and not as a nominee or agent, and not with
a view to the resale or distribution of any part thereof, and each Member has no
present intention of selling, granting any participation in, or otherwise
distributing the same. Each Member further represents that he does not have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participation to such person or to any third person, with
respect to any of Chiste's Preferred Shares.

            (b) Each Member understands that Chiste's Preferred Shares are not
registered under the Securities Act, that the issuance of Chiste's Preferred
Shares (and the underlying Conversion Shares) is intended to be exempt from
registration under the Securities Act pursuant to Section 4(2) thereof, and that
Chiste's reliance on such exemption is predicated on the Member's
representations set forth herein. Each Member represents and warrants that: (i)
he is an "accredited investor" as that term is defined in Rule 501(a) of
Regulation D under the Act, (ii) he can bear the economic risk of his respective
investments, and (iii) he possesses such knowledge and experience in financial
and business matters that he is capable of evaluating the merits and risks of
the investment in Chiste and its securities.

            (c) Each Member acknowledges that neither the U.S. Securities
Exchange Commission ("SEC"), nor the securities regulatory body of any state or
other jurisdiction, has received, considered or passed upon the accuracy or
adequacy of the information and representations made in this Agreement.


                                       4


            (d) Each Member acknowledges that he has carefully reviewed such
information as he has deemed necessary to evaluate an investment in Chiste and
its securities. To the full satisfaction of each Member, he has been furnished
all materials that he has requested relating to Chiste and the issuance of
Chiste's Preferred Shares hereunder, and each Member has been afforded the
opportunity to ask questions of Chiste's representatives to obtain any
information necessary to verify the accuracy of any representations or
information made or given to the Members. Notwithstanding the foregoing, nothing
herein shall derogate from or otherwise modify the representations and
warranties of Chiste set forth in this Agreement, on which each of the Members
have relied in making an exchange of his Interests for Chiste's Preferred
Shares.

            (e) Each Member understands that Chiste's Preferred Shares (and the
underlying Conversion Shares) may not be sold, transferred, or otherwise
disposed of without registration under the Securities Act or an exemption
therefrom, and that in the absence of an effective registration statement
covering Chiste's Preferred Shares (and the underlying Conversion Shares) or any
available exemption from registration under the Securities Act, Chiste's
Preferred Shares (and the underlying Conversion Shares) may have to be held
indefinitely. Each Member further acknowledges that Chiste's Preferred Shares
(and the underlying Conversion Shares) may not be sold pursuant to Rule 144
promulgated under the Securities Act unless all of the conditions of Rule 144
are satisfied (including, without limitation, Chiste's compliance with the
reporting requirements under the Securities Exchange Act of 1934, as amended
("Exchange Act")).

or both), any modification or termination of any such Governmental
Actions/Filings. Except as set forth in Schedule 4.21, to Chiste's knowledge, no
Governmental Action/Filing is necessary to be obtained, secured or made by

Reserve").

material limitation on the ability of any of them to conduct their business or
to own or exercise control of such assets, properties and stock.

(collectively, the "Chiste Indemnified Parties") against (i) any and all
liabilities, obligations, losses, damages, claims, actions, Liens and
deficiencies which exist, or which may be imposed on, incurred by or asserted
against any one or more of the Chiste Indemnified Parties, (1) based upon,
resulting from or arising out of, or as to which there was, any breach or

Agreement, or any statement, agreement or covenant made by such Member in or
pursuant to this Agreement, any Exhibit or Schedule hereto or thereto, or any

(ii) any cost or expense (including reasonable attorneys' fees and court costs)
incurred by the Chiste Indemnified Parties or any of them in connection with the
foregoing (including, without limitation, any cost or expense incurred by the
Chiste Indemnified Parties in enforcing their rights pursuant to this Section

                                       43


      A Chiste Indemnified Party may apply all demands or claims for
indemnification under this Section 8.2 against any payment to be made by or on
behalf of such Chiste Indemnified Party or any of its affiliates to or for the
account of such Member by means of set-off, reduction or otherwise. No Chiste
Indemnified Party shall be required to make any claim or demand against Company
or any other Person prior to the making of any claim or demand for
indemnification or at any other time. The rights of the Chiste Indemnified
Parties under this Section 8.2 are in addition to such other rights and remedies
which they may have under this Agreement or otherwise. The amount of any and all
Damages suffered by Chiste Indemnified Parties under this Section 8.2 shall be
recovered, and all claims of Chiste Indemnified Parties pursuant to this Section
8.2 shall be brought, by Chiste on behalf of such Chiste Indemnified Parties.

      Notwithstanding any other provision of this Agreement, except for any
Misrepresentation Claim (as defined in this Section 8.2) with respect to which
such Member has Knowledge (as defined in this Section 8.2), no demand or claim
for indemnification under this Section 8.2 may be made after 11:59 p.m. U.S.
Eastern Time on the date one (1) year following the Closing Date. No demand or
claim for indemnification under this Section 8.2 for any Misrepresentation Claim
may be made after 11:59 p.m. U.S. Eastern Time on the second anniversary of the
Closing Date if such Member had Knowledge (as hereinafter defined) with respect
to such Misrepresentation Claim.

      For purposes of this Agreement, (1) the term "Misrepresentation Claim"
means a claim or demand for indemnification based upon, resulting from or
arising out of any material breach or inaccuracy of a warranty or representation
and such material breach or inaccuracy was the direct and primary cause of the
Damages for which indemnification is sought; and (2) the term "Knowledge" means
in respect of any Misrepresentation Claim, as of the Closing Date or at any time
prior thereto, (a) actual knowledge of the material breach or inaccuracy upon
which such Misrepresentation Claim is based, or (b) actual knowledge of facts
which would cause a reasonable person, having knowledge and a full understanding
of the terms of this Agreement, to be aware of or recognize the material breach
or inaccuracy upon which the Misrepresentation Claim is based.

      8.3 Procedure for Indemnification Claims.


                                       44


            (a) The persons seeking indemnity under this Article VIII are
referred to collectively herein as "Indemnified Parties", and the Persons from
whom indemnification is sought pursuant to this Article VIII are referred to
herein as "Indemnifying Parties".

            (b) If at any time an Indemnified Party determines to assert a right
to indemnification hereunder, the Indemnified Party shall give to the
Indemnifying Party written notice describing the matter for which
indemnification is sought in reasonable detail. In the event that a demand or
claim for indemnification is made hereunder with respect to a matter the amount
or extent of which is not yet known or certain, the notice of demand for
indemnification shall so state, and, where practicable, shall include an
estimate of the amount of the matter. The failure of an Indemnified Party to
give notice of any matter to the Indemnifying Party shall not relieve the
Indemnifying Party of any liability which the Indemnifying Party may have to any
Indemnified Party.

            (c) Within 15 days after receipt of the notice referred to in clause
(b) above, the Indemnifying Party from whom indemnification is sought shall (i)
if true, acknowledge in writing his responsibility for all or part of such
matter, and shall pay or otherwise satisfy the portion of such matter as to
which responsibility is acknowledged or take such other action as is reasonably
satisfactory to the Indemnified Party to resolve any such matter that involves
anyone not a party hereto or (ii) give written notice to the Indemnified Party
of his intention to dispute or contest all or part of such responsibility. Upon
delivery of such notice of intention to contest, the parties shall negotiate in
good faith to resolve as promptly as possible any dispute as to responsibility
for, or the amount of, any such matter. Failure to respond to a notice claiming
indemnification shall be deemed a denial of responsibility therefore.

            (d) In the event that the Indemnified Party is required to expend
any amount in enforcing its rights of indemnification hereunder, the
Indemnifying Parties will, jointly and severally, promptly upon request, pay
such amounts to the Indemnified Party if indemnification is required to be made
hereunder.

            (e) Each Indemnifying Party shall have the right to employ separate
counsel in any action or claim which is brought against any Indemnified Party in
respect of which indemnity may be sought from it, and to participate in the
defense of such action or claim, if such Indemnifying Party confirms in writing
its responsibility for such action or claim; provided, however, that (i) the
Indemnified Party or Parties shall retain control of such action or claim and
(ii) the fees and expenses of such separate counsel shall be at the expense of
the Indemnifying Party.

this Agreement or if such breach by Company or Members is cured during such
thirty (30)-day period): or

            (f) by Chiste, if the Company is unable to obtain the signature of

Preferred Shares to be delivered to the Members hereunder, and the certificates

      11.2 Interpretation.

            (a) When a reference is made in this Agreement to Exhibits, such
reference shall be to an Exhibit to this Agreement unless otherwise indicated.
When a reference is made in this Agreement to Sections, such reference shall be
to a Section of this Agreement. Unless otherwise indicated the words "include,"
"includes" and "including" when used herein shall be deemed in each case to be
followed by the words "without limitation." The table of contents and headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. When reference is
made herein to "the business of" an entity, such reference shall be deemed to
include the business of all direct and indirect Subsidiaries of such entity.
Reference to the Subsidiaries of an entity shall be deemed to include all direct
and indirect Subsidiaries of such entity. References to the Company shall be
deemed to include the Company and all of its direct or indirect Subsidiaries.

            (b) For purposes of this Agreement, the term "Material Adverse
Effect" when used in connection with an entity means any change, event,
violation, inaccuracy, circumstance or effect, individually or when aggregated
with other changes, events, violations, inaccuracies, circumstances or effects,
that is materially adverse to the business, assets (including intangible
assets), revenues, financial condition or results of operations of such entity
and its Subsidiaries, if any, taken as a whole (it being understood that neither

constitute a Material Adverse Effect: (a) changes attributable to the public
announcement or pendency of the transactions contemplated hereby, (b) changes in
general national or regional economic conditions, (c) changes affecting the
industry generally in which Company or Chiste operates, or (d) any SEC
rulemaking requiring enhanced disclosure of reverse merger transactions with a

                                       50


            (c) For purposes of this Agreement, the term "Person" shall mean any
individual, corporation (including any non-profit corporation), general

estate, trust, company (including any limited liability company or joint stock
company), firm or other enterprise, association, organization, entity or
Governmental Entity.

            (b) For purposes of this Agreement, all monetary amounts set forth
herein are referenced in United States dollars, unless otherwise noted.

      11.3 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

      11.4 Entire Agreement; Third Party Beneficiaries. This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Schedules hereto (a)
constitute the entire agreement among the parties with respect to the subject
matter hereof and supersede all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof,
it being understood that Sections 10.b. and 10.c. of the Letter of Intent shall
continue in full force and effect until the Closing and shall survive any
termination of this Agreement; and (b) are not intended to confer upon any other
person any rights or remedies hereunder (except as specifically provided in this
Agreement). KRM Fund is a third-party beneficiary of the certain provisions
contained herein to which KRM Fund derives a benefit and, with respect to such
provisions, KRM Fund has the right to enforce them as if it were a signatory to
this Agreement.

      11.5 Severability. In the event that any provision of this Agreement, or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

      11.6 Other Remedies; Specific Performance. Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or injunctions to prevent
breaches of this Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having jurisdiction, this
being in addition to any other remedy to which they are entitled at law or in
equity.


                                       51


      11.7 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Nevada, USA, regardless of the laws
that might otherwise govern under applicable principles of conflicts of law
thereof.

      11.8 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

      11.9 Assignment. No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Subject to the first sentence of this Section 11.9, this
Agreement shall be binding upon and shall inure to the benefit of the parties
hereto and their respective successors and permitted assigns.

      11.10 Arbitration. Any disputes or claims arising under or in connection
with this Agreement or the transactions contemplated hereunder shall be resolved
by binding arbitration. Notice of a demand to arbitrate a dispute by either
party shall be given in writing to the other at their last known address.
Arbitration shall be commenced by the filing by a party of an arbitration demand
with the American Arbitration Association ("AAA") in its office in New York, New
York USA. The arbitration and resolution of the dispute shall be resolved by a
single arbitrator appointed by the AAA pursuant to AAA rules. The arbitration
shall in all respects be governed and conducted by applicable AAA rules, and any
award and/or decision shall be conclusive and binding on the parties. The
arbitration shall be conducted in New York, New York USA. The arbitrator shall
supply a written opinion supporting any award, and judgment may be entered on
the award in any court of competent jurisdiction. Each party shall pay its own
fees and expenses for the arbitration, except that any costs and charges imposed
by the AAA and any fees of the arbitrator for his services shall be assessed
against the losing party by the arbitrator. In the event that preliminary or
permanent injunctive relief is necessary or desirable in order to prevent a
party from acting contrary to this Agreement or to prevent irreparable harm
prior to a confirmation of an arbitration award, then either party is authorized
and entitled to commence a lawsuit solely to obtain equitable relief against the
other pending the completion of the arbitration in a court having jurisdiction
over the parties. All rights and remedies of the parties shall be cumulative and
in addition to any other rights and remedies obtainable from arbitration.
