          c. The right to avail  itself of all  rights  and  remedies  granted a
secured  party  under the  Uniform  Commercial  Code as in force in the State of
Arizona, including, without limiting the generality of the foregoing:

          (i) The right to sell the Collateral,  or any part thereof,  in one or
     more sales, according to the provisions of Section 4 hereof; and

          (ii) The right to take all necessary  actions,  by means of the powers
     granted to Pledgee  herein,  to take title to the  Collateral as sole owner
     thereof,  and to exercise any and all right  pertaining to ownership of the
     Collateral; but Pledgee shall have no duty to exercise any of the aforesaid
     rights,  privileges  or options.  Any cash received and retained by Pledgee
     hereunder  shall be applied to  payment  of the  Obligations  in the manner
     specified in Section 5 hereof.

     4. Sale of  Collateral.  Pursuant to Its option  under  Section  3(c),  and
subject to the terms and conditions hereof, Pledgee may sell, assign and deliver
the Collateral or any part thereof, at public or private sale,  conducted by any
officer, or agent of, or auctioneer or attorney for, Pledgee, at Pledgee's place
of business or elsewhere,  for cash, upon credit or future delivery, and at such
price or prices as Pledgee shall, in its reasonable discretion,  determine,  and
Pledgee may be the purchaser of any or all of the Collateral so sold.

                                       3
<PAGE>
     Upon any such sale,  Pledgee shall have the right to direct Escrow Agent to
deliver,  assign and transfer to the purchaser  thereof the  Collateral so sold.
Each  purchaser at any such sale shall hold the  Collateral  so sold  absolutely
free from any claim or right of whatsoever kind, including,  without limitation,
any equity or right of redemption of Pledgor,  which Pledgor hereby specifically
waives to the extent Pledgor may lawfully do so.

     Pledgee  shall give  Pledgor at least ten (10) days  written  notice of any
such public or private sale.  Such notice,  in the case of a public sale,  shall
state the time and place fixed for such sale. Any such public sale shall be held
at such time or times within ordinary business hours as Pledgee shall fix in the
notice of such sale. At any sale,  the  Collateral may be sold as an entirety or
in partial  interests.  Pledgee shall not be obligated to make any sale pursuant
to such  notice,  but if no such  sale is made or only a  partial  sale is made,
Pledgee shall give notice as provided above prior to any subsequent sale. In the
case of any sale of all or any part of the  Collateral  on credit or for  future
delivery,  the  Collateral  so sold may be retained  by Escrow  Agent or Pledgee
until the selling price is paid by the purchaser thereof,  but Pledgee shall not
incur any liability in case of the failure of such  purchaser to take up and pay
for the Collateral so sold, and in case of any such failure, such Collateral may
again be sold  under  and  pursuant  to and in  compliance  with the  provisions
hereof.

     The receipt of Pledgee of the purchase  money paid at any such sale made by
it shall be a sufficient  discharge  therefor to any purchaser of the Collateral
or any portion thereof, and no such purchaser,  after paying such purchase money
and receiving  such receipt,  shall be bound to see to the  application  of such
purchase money or any part thereof or in any manner whatsoever be answerable for
any loss,  misapplication or  non-application of any such purchase money, or any
part  thereof,  or be  bound  to  inquire  as to the  authorization,  necessity,
expediency or regularity of any such sale.

     Pledgor  recognizes that  registration of the Collateral  under federal and
state  securities  laws may be  impractical  because of the  expenses  or delays
involved  in the  registration  processes  and  that  in  the  absence  of  such
registration,  Pledgee may be unable to effect a public sale of all or a part of
the Collateral, but may be compelled to resort to one or more private sales to a
restricted group of purchasers who will be obliged to agree,  among other things
to acquire such Collateral for their own account, for investment, and not with a
view to the distribution or resale thereof. Pledgor agrees that private sales so
made may be at prices and other terms less  favorable to the seller than if such
Collateral  were sold at public  sales,  and that Pledgee has no  obligation  to
delay sale of any such  Collateral  for the period of time  necessary  to permit
such  Collateral to be registered  for public sale under the  Securities  act of
1933, as amended,  and any applicable blue sky or other stare  securities  laws.
Pledgor  agrees that sales made under the foregoing  circumstances  shall not be
deemed to have been made in a commercially  unreasonable manner by virtue of any
terms less  favorable to the seller  resulting  from the private  nature of such
sales.

     Pledgor shall be liable for reasonable  attorneys'  fees and legal expenses
incurred by Pledgee in enforcing any of its rights or remedies hereunder.

     5. Application of Proceeds.  The proceeds of any sale of all or any part of
the Collateral shall be applied in the following order or priorities:

     First,  to the payment of all costs and  expenses of such sale,  including,
without  limitation,  reasonable  compensation to Escrow Agent,  Pledgee,  their
agents and attorneys, and all other expenses,  liabilities and advances incurred
or made by Escrow Agent or Pledgee,  their agents and  attorneys,  in connection
with said sale,  and any other  unreimbursed  expenses for which  Pledgee may be
reimbursed pursuant to the provisions hereof;

     Second,  to the  payment of the Note with no amounts  applied to payment of
principal until all interest has been paid;

                                       4
<PAGE>
     Third, to the payment or satisfaction of any other Obligations; and

     Fourth, to the payment to Pledgor,  Pledgor's  successors or assigns, or to
whomsoever  may be  lawfully  entitled  to  receive  the same,  or as a court of
competent  jurisdiction  may direct,  of any surplus  then  remaining  from such
proceeds.

     6. Escrow Agent Appointment  Attorney-in-Fact.  Indemnity.  Escrow Agent is
hereby  appointed  the  Attorney-in-fact,  with full power of  substitution,  of
Pledgor  during the  continuances  of any Event of  Default,  for the purpose of
carrying  out the  provisions  of this  Agreement  and  taking  any  action  and
executing any  instrument to accomplish the purposes  hereof.  Pledgor agrees to
indemnify  and hold  harmless  Escrow  Agent and  Pledgee  from and  against any
liability or damage which they may incur in the exercise and  performance of any
of the powers and duties as specifically set forth herein.

     7. Termination of Pledge.  When all of the Obligations shall have been paid
and  performed  and the terms and  covenants  hereof and  agreements  of Pledgor
hereunder  have been  performed in full,  this Agreement  shall  terminate,  and
Escrow  Agent  shall  forthwith  assign.  transfer  and  deliver  to  Pledgor or
Pledgor's  designees,  without  representation,  warranty or  recourse,  against
appropriate  receipts,  all the  Collateral,  if any,  then held by it in pledge
hereunder.

     8. Events of Default.  Each of the following  shall  constitute an event of
default  ("Event  of  Default")  hereunder:  if  Pledgor  shall fail to make any
