         Re:    Exclusivity Agreement with NOVA Chemicals Inc.

Dear John:

In   connection   with  the   negotiations   regarding  any   transaction   (the
"Transaction")  between Envirokare Tech, Inc.  ("Envirokare") and NOVA Chemicals
Inc.  ("NOVA"),   Envirokare  has  provided  NOVA  with  information   regarding
Envirokare and its affiliates  (specifically  Envirokare Composites Corporation)
and access to Envirokare's  management.  Subject to the terms and conditions set
forth in this Letter Agreement (the "Agreement"), NOVA wishes to investigate and
negotiate a possible Transaction.

1.  Between  the date of this  Agreement  and 5:00 p.m.  on August 31, 2004 (the
"Exclusive  Period"),  Envirokare will not, directly or indirectly,  through any
officer, director,  employee,  affiliate,  attorney,  financial advisor or other
agent,  take any action to solicit,  initiate,  seek or encourage any inquiry or
proposal from,  furnish any information to, or participate in any discussions or
negotiations  with,  any third party  (other than NOVA or an  affiliate  thereof
designated by NOVA)  regarding any  transaction  related to the use,  license or
sublicense  of the TPF  Technology  (any such  transaction  being a "Third Party
Transaction"), except as provided for in this Agreement. Envirokare agrees that,
except as  provided  in this  agreement,  it will not  accept or enter  into any
agreement  concerning any Third Party  Transaction  during the Exclusive Period.
Envirokare  shall  be  responsible  for  any  breach  of this  Agreement  by its
respective officers, directors, employees, agents, advisors or representatives.

2. During the Exclusive  Period,  Envirokare will notify NOVA immediately  after
receipt by Envirokare (or any of its officers, directors, employees, affiliates,
representatives,  advisors  or other  agents)  of any  proposal  for or  inquiry
respecting  any Third Party  Transaction.  Such notice to NOVA will  indicate in
reasonable  detail the  identity of the person or entity  making the proposal or
inquiry and the terms and conditions of such proposal or inquiry.

3.  Notwithstanding  the  restrictions  set  forth in  Sections  1 and 2 of this
Agreement,  Envirokare may pursue a Third Party Transaction provided that it (a)
provides the notices as required by Paragraph 2 herein,  (b) provides  NOVA with
the right of first refusal to proceed with Envirokare on  substantially  similar
terms and  conditions  as the  proposed  Third Party  Transaction;  and (c) NOVA
declines to proceed in such a manner.  If Envirokare  proposes to proceed with a
Third Party  Transaction  and NOVA  decides  not to exercise  its right of first
refusal,  then NOVA may  immediately  put the  Warrant  (as defined in Section 6
below) to  Envirokare  for the greater of  $250,000 or fair market  value of the
Warrant payable in cash.

4. Envirokare and NOVA continue to be bound by the terms of the  Confidentiality
Agreement  between the parties dated November 12, 2003.  Subject to the terms of
that Confidentiality Agreement, neither Envirokare nor NOVA will make any public
announcement concerning this Agreement,  the discussions or negotiations between
the parties, or any other matters relating to the proposed transaction. However,
after consultation with the other parties hereto, any party may at any time make
disclosure  if it is advised by outside  legal  counsel that such  disclosure is
required under applicable law, regulatory  authority,  or stock exchange listing
agreement.



5. During the Exclusive  Period,  Envirokare and NOVA will continue to negotiate
and  discuss  the  potential  Transaction.  In order to  provide  NOVA  with the
opportunity to continue such  discussions  and  negotiations,  Envirokare  shall
allow NOVA access to any  information  requested  by NOVA that is  necessary  to
continue its  evaluation of the proposed  transaction.  In addition,  Envirokare
will take all reasonable  steps  necessary to remedy the  intellectual  property
concerns which have been raised by NOVA during the Exclusive Period.  Envirokare
will keep NOVA apprised as to the status of such  activities on a regular basis,
and will afford NOVA the ability to review and provide  comments on the progress
of such  activities as well as any documents  that are generated to address such
intellectual property issues. NOVA shall not be under any obligation to continue
the discussions or negotiations or to proceed with any proposed  transaction for
any reason whatsoever.

6. As consideration  for such Exclusive Period on the terms discussed herein and
for the grant of warrants as provided in  Paragraph 7 herein,  NOVA shall pay to
Envirokare  the sum of two  hundred  fifty  thousand  dollars  ($250,000).  Such
payment  shall be made  immediately  following  execution of this  Agreement and
shall be  non-refundable  except in the event of any breach of this Agreement or
misrepresentation  of any information provided by Envirokare to NOVA pursuant to
this Agreement.  Immediately  following execution of this Agreement,  Envirokare
shall  issue to NOVA a Common  Stock  Purchase  Warrant in the form  attached as
Attachment A hereto (the "Warrant").

7. If the  negotiations  and discussions  detailed in this Agreement result in a
definitive  agreement  between the parties for a Transaction,  NOVA will receive
shares in Envirokare  worth the $250,000  investment at the then current  market
price. In this event, the warrants issued in conjunction with this agreement may
be cancelled at the discretion of Envirokare.(JWV)

8.  Except as  specifically  set forth in this  Agreement,  Envirokare  and NOVA
acknowledge  that this  Agreement  is not  intended  to, and does not create any
binding  obligation on any party hereto with respect to any transaction or other
agreement  between the  parties.  Any such  obligation  will only arise from the
execution of definitive agreement regarding any such transaction.

9. This  Agreement will be governed by the laws of the State of New York without
regard to its  conflict  of law  principles.  In any action  between the parties
arising  out of or  relating  to  this  Agreement  or  any  of the  transactions
contemplated  by  this  Agreement:  (i)  each  of the  parties  irrevocably  and
unconditionally  consents and submits to the exclusive jurisdiction and venue of
the State and Federal  courts  located in New York,  New York;  (ii) if any such
action is commenced in a state court then,  subject to applicable  law, no party
shall object to the removal of such action to any Federal  Court  located in New
York, New York; (iii) each of the parties  irrevocably  waive the right to trial
by jury; and (iv) each of the parties irrevocably consents to service of process
by first class certified mail, return receipt requested, postage prepaid.

10. The parties agree that monetary damages would not be a sufficient remedy for
any breach of this  Agreement by  Envirokare  and that NOVA shall be entitled to
equitable relief, including injunction and specific performance, as a remedy for
such breaches.  Such remedy shall not be deemed to be the exclusive remedy for a
breach by  Envirokare of this  Agreement,  but shall be in addition to all other
remedies  available  at law or equity  to NOVA.  This  Agreement  (A) may not be
amended  or  modified  except by an  instrument  in  writing  and signed by both
parties; and (B) may be executed in one or more counterparts, each of which when
executed shall be deemed to be an original but all of which taken together shall
constitute one and the same Agreement.

Please  acknowledge your acceptance of and agreement to the foregoing by signing
and returning to the undersigned as soon as possible.

Sincerely,

NOVA Chemicals Inc.
