      proceeding, or investigation pending or currently threatened against PPTI,
      and
      (ii) in PPTI’s reasonable judgment, none of such disclosures are likely to
      question the validity of this Agreement, or the right of PPTI to enter into
      such
      agreements, or to consummate the transactions contemplated hereby or thereby,
      or
      which might result, either individually or in the aggregate, in any material
      adverse change in the assets, condition, affairs, or property of PPTI,
      financially or otherwise, or any change in the current equity ownership of

      regulation, license, or permit applicable to PPTI, the violation or default

      business and for the Purchaser’s analysis of the financial future and viability
      of PPTI and desirability of the terms of this investment. The Purchaser
      acknowledges that neither PPTI nor any officer or director of PPTI is making
      any
      representation or warranty regarding any financial projections previously given
      to the Purchaser or the assumptions underlying such financial projections,
      as
      such financial projections are subject to significant business, economic and
      other uncertainties and contingencies. The Purchaser acknowledges that if PPTI
      is not able to operate profitably or generate positive cash flows, PPTI may
      have
      difficulty meeting its obligations and may not be able to continue to operate
      its business, and the Purchaser could lose all of his investment. The Purchaser
      has such knowledge and experience in financial and business matters that he
      is
      capable of evaluating the merits and risks of the purchase of the Shares
      pursuant to the terms of this Agreement and of protecting his interest in

      laws, (ii) other laws of general application affecting the enforcement of
      creditors' rights generally and general principles of equity, (iii) the
      discretion of the court before which any proceeding therefor may be brought,

      Purchaser is required in connection with the valid execution, delivery and
      performance of the Agreement.




4.6  Taxes . The
      Purchaser has not relied on any statements or representations of PPTI or any

      contemplated by this Agreement.




4.7  Restricted

      the laws of any state and may not be sold or transferred, or otherwise disposed
      of, without registration under the Securities Act and applicable state
      securities laws, or pursuant to an exemption therefrom. In the absence of an
      effective registration statement or an exemption therefrom covering the Shares
      and the Common Stock issuable upon exercise of the Warrants, the Purchaser
      will
      sell or transfer, or otherwise dispose of, the Shares to be acquired by him

8.  Indemnity .
      PPTI
      shall, with respect to the representations, warranties, covenants and agreements
      made by it herein indemnify, defend and hold each Purchaser and his employees,
      partners, agents, counsel and affiliates (each, an “ Indemnified
      Party ”)
      harmless from and against all liability, loss or damage, together with all
      reasonable costs and expenses related thereto (including legal and accounting
      fees and expenses), arising from the untruth, inaccuracy or breach of any such
      representations, warranties, covenants or agreements of PPTI contained in this
      Agreement or the assertion of any claims relating to the foregoing. Without
      limiting the generality of the foregoing, each Indemnified Party shall be deemed
      to have suffered liability, loss or damage as a result of the untruth,
      inaccuracy or breach of any such representations, warranties, covenants or
      agreements if such liability, loss or damage shall be suffered by the
      Indemnified Party as a result of, or in connection with, such untruth,
      inaccuracy or breach or any facts or circumstances constituting such untruth,
      inaccuracy or breach. PPTI shall indemnify and hold harmless each Indemnified
      Party against any losses, claims, damages or liabilities, joint or several,
      to
      which any of the foregoing persons may become subject, insofar as such losses,
      claims, damages or liabilities (or actions in respect thereof) arise out of
      or
      are based upon any violations by PPTI of the Securities Act or state Blue Sky
      laws applicable to PPTI relating to action or inaction required of PPTI in
      connection with the Securities Act or registration or qualification under such
      state Blue Sky laws; and shall reimburse each such Indemnified Party for any
      legal or any other expenses reasonably incurred by any of them in connection
      with investigating or defending any such loss, claim, damage, liability or
      action; provided , however ,
      that no
      indemnification shall be required hereunder for the gross negligence or willful
      misconduct of any Indemnified Party or material breach by a Purchaser of any
      of
      the representations and warrants set forth in Section
      4 hereof.
      In case any such action is brought against an Indemnified Party, PPTI will
      be
      entitled to participate in and assume the defense thereof with counsel
      reasonably satisfactory to such Indemnified Party, and after notice from PPTI
      to
      such Indemnified Party of its election to assume the defense thereof, PPTI
      shall
      be responsible for any legal or other expenses subsequently incurred by the
      latter in connection with the defense thereof, provided that if any Indemnified
      Party shall have reasonably concluded that there may be one or more legal
      defenses available to such Indemnified Party that conflict in any material
      respect with those available to PPTI, or that such claims or litigation involves
      or could have an effect upon matters beyond the scope of the indemnity provided
      by this Section
      8 ,
      PPTI
      shall reimburse such Indemnified Party and shall not have the right to assume
      the defense of such action on behalf of such Indemnified party and PPTI shall
      reimburse each such Indemnified Party and any individual, partnership, limited
      liability company, corporation, joint stock company, trust, estate, joint
      venture, association or unincorporated organization, or any other form of
      business or professional entity (“Person”) controlling such Indemnified Party
      for that portion of the reasonable fees and expenses of any counsel retained
      by
      the Indemnified Party. PPTI shall not make any settlement of any claims
      indemnified against hereunder without the written consent of the Indemnified
      Party or Parties, which consent shall not be unreasonably withheld. Any claim
      for indemnification under this Section
      8 with
      respect to representations and warranties must be made not later than the end
      of
      the 12-month survival period set forth in Section
      9.2 .
