          arrange for the credit to be extended to NEWCO as required under
          Section 3(b), and (iv) there are no actions or proceedings pending, or
          to either's knowledge, threatened, which would prevent or make
          unlawful the consummation of the transactions contemplated by this
          Agreement.

     (c)  The parties represent and warrant to each other that neither of them
          shall liquidate its ownership of NEWCO without first offering to the
          other of them the right to obtain the liquidating party's ownership
          upon the same or better term's to the liquidating party as offered by
          a third party.

     (d)  The parties agree that NEWCO shall warrant the Licensed Products to be
          free from defects in material and workmanship upon such terms as shall
          be agreed to in writing between NEWCO and its customers.  NEWCO shall
          indemnify and hold Aura and Majority Owner harmless from all loss
          resulting from the manufacture, use or sale of licensed products.

7.   INSURANCE

     (a)  NEWCO shall at all times during the term of this Agreement and
          thereafter carry Director and Officer insurance, business interruption
          insurance, hazard (including, but not limited to fire, earthquake,
          flood, theft and burglary) and general liability insurance, and any
          other insurance required under law, covering acts, omissions or
          occurrences during the term of this Agreement, in the amount of the
          actual replacement value of building, equipment and inventory, per
          occurrence (or such other amount as the parties shall determine to be
          reasonable). Such policies shall name AURA and Majority Owner as
          additional insureds and beneficiaries in the same percentages of their
          respective stock ownership in NEWCO.  NEWCO shall use its best efforts
          to obtain a policy which provides that it shall not be cancellable
          except upon thirty (30) days prior written notice to AURA and Majority
          Owner.  NEWCO agrees to provide Aura and Majority Owner with one or
          more certificates evidencing the insurance coverage hereunder and the
          insurance policies promptly upon the request of Aura and/or Majority
          Owner.  Aura, Majority Owner and NEWCO acknowledge that insurance
          markets are rapidly changing and that insurance in the form and
          amounts described in this paragraph may not be available in the
          future. In such event, NEWCO shall nevertheless maintain insurance
          coverage which is customary and commercially reasonable.

          fails to perform such covenant following thirty (30) days' written
          notice from the other party and opportunity to cure, provided,
          however, if the default is of such a nature that it cannot reasonably
          be cured within such thirty (30)-day period, then the defaulting party
          shall not be deemed to be in default so long as the defaulting party
          promptly commences to cure such default and diligently pursues such
          cure to completion;  (ii) Any representation or warranty of either
          party herein shall prove to be incorrect in any material respect;

          hereunder; or (iv) Majority Owner or AURA makes a general assignment
          or general arrangement for the benefit of creditors without the prior
          written consent of the other party, a petition for adjudication of

          or a substantial portion of either party's assets shall be subjected
          to attachment, execution or other judicial seizure which is not
          discharged, stayed or bonded within sixty (60) days.

     (b)  If a Default shall occur hereunder, either party shall have the right,
          to be exercised by it in its sole discretion (after reasonable
          opportunity to cure the default has been given), to terminate this
          Agreement upon written notice to the defaulting party.  The right of
          either party to terminate this Agreement for Default shall be in
          addition to any other rights or remedies to which either party shall
          be entitled at law.  Termination of this Agreement shall be without
          prejudice to any rights or remedies which either party may have, under
          this Agreement

     (c)  In the event this Agreement is terminated by Aura by reason of default
          of Majority Owner, then the license granted to NEWCO under Section
          4(a) shall terminate and revert to Aura.

          law of a government having jurisdiction and respect of this Agreement,

          impossible or prohibit, restrain, modify or eliminate any act or
          obligation of Majority Owner under this Agreement, Aura shall have the
          right, at its option, to suspend this Agreement or to make such
