         Chelsea represents and warrants as follows:

                  (i)      Chelsea is a corporation duly organized,  and validly
                           existing under the laws of the state of Delaware.

                  (ii)     Chelsea acknowledges that the receipt of Common Stock
                           as  compensation  involves a high  degree of risk and
                           further  acknowledges  that it can bear the  economic
                           risk of compensation in Common Stock;

                  (iii)    Chelsea  understands and acknowledges that the Common
                           Stock being issued pursuant to this Agreement will be
                           issued  in  reliance  on  specific   exemptions  from
                           registration   requirements   of  federal  and  state
                           securities  laws  and that  TAC is  relying  upon the
                           truth   and   accuracy   of   the    representations,
                           warranties,    agreements,     acknowledgments    and
                           understandings  of Chelsea set forth  herein in order
                           to determine the applicability of such exemptions and
                           the  suitability  of Chelsea  to  acquire  the Common
                           Stock;

                  (iv)     Chelsea is sufficiently  experienced in financial and
                           business  matters  to be capable  of  evaluating  the
                           merits and risks of receiving  Common  Stock,  and to
                           make an informed decision relating thereto.  Further,
                           it is an  "accredited  investor"  as  defined  in the
                           Securities Act of 1933;

                  (v)      Chelsea has consulted its own investment and/or legal

                  (vi)     Chelsea   understands   that  in  the   view  of  the
                           Securities  and  Exchange  Commission  the  statutory
                           basis for the exemption  claimed for this transaction
                           would not be present if the  offering of Common Stock
                           or  option  to  purchase  Common  Stock  is part of a
                           scheme or plan to evade the  registration  provisions
                           of the Securities Act of 1933.  Chelsea confirms that
                           this  transaction  is not  part of any  such  plan or
                           scheme.

                  (vii)    Chelsea is not an  underwriter  of, or dealer in, the
                           Common Stock and it is not participating, pursuant to
                           a contractual  agreement,  in the distribution of the
                           Common Stock.


                   (viii)  Chelsea hereby acknowledges that it has been provided
                           with  audited  financial  statements  of TAC  for the
                           years ending  December 31, 1995 and 1996,  as well as
                           such other documents as Chelsea  considers  necessary
                           in  acquiring  the  shares  of TAC  pursuant  to this
                           transaction. Chelsea further acknowledges that it has
                           been afforded the  opportunity  to inspect or request
                           such further documents as may be necessary to make an
                           informed decision concerning whether or not to accept
                           TAC shares pursuant to this Agreement.

2.       Representations of TAC

         TAC represents and warrants as follows:

                  (i)      The  Company  is a  corporation  duly  organized  and
                           validly existing under the laws of the State of Utah.

                  (ii)     TAC has all necessary  corporate  power and authority

                           provisions  of law to own its  properties  and  other
                           assets now owned by it, to carry on  business  as now
                           being conducted, and to execute and deliver and carry
                           out the provisions of this Agreement.

                  (iii)    All corporate  action on the part of TAC required for
                           the lawful  execution and delivery of this  Agreement
                           and  the  issuance,  execution  and  delivery  of the
                           Shares  will have been  duly and  effectively  taken.
                           Upon  execution and  delivery,  this  agreement  will

                           enforceable in accordance  with its terms,  except as
                           the  enforceability  may  be  limited  by  applicable
                           bankruptcy,  insolvency  or similar laws and judicial
                           decisions affecting creditors' rights generally.

3.       Transfer of TAC Common Stock.  The shares to be issued  hereunder shall

         provided by Rule 504 of Regulation D promulgated  under the  Securities
         Act of 1933 and exemptions from applicable state registration.  Chelsea
         hereby agrees to obtain an opinion of independent counsel, satisfactory
         to the  counsel of TAC, to the effect that the resale of such shares is

         selling the Common Stock to be transferred to it under this Agreement.

4.       Exemption;  Reliance on  Representations.  Chelsea understands that the
         TAC Common Stock has not been  registered  under the  Securities Act of

         issue one or more stock  certificates  representing the Common Stock in
         the name of Chelsea and bearing the following legend:

         The  securities  evidenced  hereby have not been  registered  under the
         Securities Act of 1933, as amended (the"Act"),  nor qualified under the
         securities  laws of any states,  and have been issued in reliance  upon
         exemptions  from such  registration  and  qualification  for non-public
         offerings.  Accordingly, the sale, transfer, pledge, hypothecation, and
         or other disposition of any such securities or any interest therein may
         not  be  accomplished  except  pursuant  to an  effective  registration
         statement or exemption under the Act and qualification under applicable
         State   securities   laws,  or  pursuant  to  an  opinion  of  counsel,
         satisfactory  in form and  substance to the Issuer,  to the effect that
         such registration or exemption and qualification are not required.

         TAC represents  that these Shares shall be freely  transferable  on the
         books  and  records  of  TAC  subject  to  compliance  with  applicable
         securities laws.
