STOCK OPTION AGREEMENT

         THIS STOCK OPTION AGREEMENT (this "Agreement") is entered into
effective as of October 10, 2000 (the "Grant Date"), by Volu-Sol, Inc., a Utah
corporation (the "Company") and David G. Derrick (the "Holder").

                                    RECITALS

     A. The Company has adopted the  Volu-Sol,  Inc. 1997  Transition  Plan (the
"Plan"), a copy of which has been provided to the Holder (capitalized terms that
are used but not defined in this  Agreement  will have the meanings  given those
terms in the Plan).

     B. The Holder is an employee of the  Company or one of its  Affiliates  (as
defined in the Plan), and has been designated by the Administrative Committee to
receive a stock option under the Plan.

NOW, THEREFORE, the Company and the Holder covenant and agree as follows:

     1. GRANT OF THE  OPTION.  The Company  hereby  grants to the Holder a stock
option  (the  "Option")  to  acquire  from the  Company  Five  Hundred  Thousand
(500,000)  shares of the Common  Stock,  par value  $.0001,  of the Company (the
"Common  Stock"),  at the price of $1.00 per share  (the  "Option  Price").  The
Option is not intended to qualify as an "incentive  stock option",  as that term
is defined in Section 422 of the Internal Revenue Code of 1986, as amended.

     2. TERM OF THE OPTION.  Unless  earlier  terminated in accordance  with the
provisions  of the Plan,  the Option will  terminate on the earliest to occur of
(a) the  expiration of Ten (10) years from the Grant Date; (b) the expiration of
ninety (90) days  following  termination  of the  Holder's  employment  with the
Company for any reason other than death, disability or cause; (c) the expiration
of one (1)  year  following  termination  of the  Holder's  employment  with the
Company on account of death or  disability;  and (d) the date of  termination of
the Holder's employment with the Company for cause.

     3. VESTING.  This Option may be exercised at any time and from time to time
in  accordance  with its  terms  beginning  on the date of grant  and  ending at
midnight (Salt Lake City, Utah time) on October 9, 2005.

         4. OTHER LIMITATIONS OF THE OPTION. The Option is subject to all of the
provisions of the Plan, which permits adjustments to the Option upon the
occurrence of certain corporate events such as stock dividends, extraordinary
cash dividends, reclassifications, recapitalizations, reorganizations,
split-ups, spin-offs, combinations, exchanges of shares, and warrants or rights
offerings and which applies in the event of an Approved Transaction or Control
Purchase.

     5. EXERCISE OF THE OPTION.  To exercise the Option,  the Holder must do the
following:

                  (a) deliver to the Company a written notice, in the form
         attached to this Agreement as Exhibit A, specifying the number of
         shares of Common Stock for which the Option is being exercised;

                  (b)      surrender this Agreement to the Company;


                                       1



                  (c) tender payment of the aggregate Option Price for the
         shares for which the Option is being exercised, which payment may be
         made (i) in cash or by check; or (ii) by such other means as the
         Administrative Committee, in its sole discretion, shall permit at the
         time of exercise;

                  (d) pay, or make arrangements satisfactory to the
         Administrative Committee for payment to the Company of all federal,
         state and local taxes, if any, required to be withheld by the Company
         in connections with the exercise of the Option; and

                  (e) execute and deliver to the Company the documents required
         by the Plan and any other documents required from time to time by the
         Administrative Committee in order to promote compliance with applicable
         laws, rules and regulations.

     6. DELIVERY OF SHARE  CERTIFICATE.  As soon as practicable after the Option
has been duly  exercised,  the Company will deliver to the Holder a  certificate
for the shares of Common  Stock for which the Option was  exercised.  Unless the
Option has expired or been  exercised in full,  the Company and the Holder agree
to execute a new Stock Option Agreement, covering the remaining shares of Common
Stock that may be acquired upon exercise of the Option,  which will be identical
to this  Agreement  except as to the  number of shares of Common  Stock  subject
thereto.  In lieu of replacing  this  Agreement in such manner,  the Company may
affix to this Agreement an appropriate  notation indicating the number of shares
for which the Option was exercised and return this Agreement to the Holder.

     7. NONTRANSFERABILITY. The Option is not transferable other than by will or
the laws of descent and distribution, and the Option may be exercised during the
lifetime of the Holder only by the Holder or the Holder's court  appointed legal
representative.

     8.  WARRANTIES  AND  REPRESENTATIONS  OF  THE  HOLDER.  By  executing  this
Agreement, the Holder accepts the Option,  acknowledges receipt of a copy of the
Plan and the Prospectus, and agrees to comply with all of the provisions of this
Agreement and the Plan.

     9.  RIGHTS  OF THE  SHAREHOLDER.  The  Holder  will  have  no  rights  as a
shareholder  of the  Company on account of the Option or on account of shares of
Common Stock that will be acquired upon exercise of the Option (but with respect
to which no certificates have been issued).

     10. TAX  WITHHOLDING.  The Holder  agrees to pay,  or to make  arrangements
satisfactory to the Administrative  Committee for payment to the Company of, all
federal,  state and local income and employment  taxes,  if any,  required to be
withheld by the  Company in  connection  with the  exercise of the Option or any
sale,  transfer or other disposition of any shares of Common Stock acquired upon
exercise of the  Option.  If the Holder  fails to do so, then the Holder  hereby
authorizes  the  Company  to deduct  all or any  portion  of such taxes from any
payment of any kind otherwise due to the Holder.

     11. FURTHER ASSURANCES. The Holder agrees from time to time to execute such
additional  documents as the Company may  reasonably  require to effectuate  the
purposes of the Plan and this Agreement.

     12. BINDING EFFECT. This Agreement shall be binding upon the Holder and the
Holder's heirs, successors and assigns.

         13. ENTIRE AGREEMENT; MODIFICATIONS. This agreement, together with the
Plan and agreements referenced in this Agreement and/or the Plan, constitutes
the entire agreement and understanding between the Company and the Holder
regarding the subject matter hereof. Except as otherwise provided in the Plan,

                                       2



no modification of the Option or this Agreement, or waiver of any provision of
this Agreement or the Plan, shall be valid unless in writing and duly executed
by the Company and the Holder. The failure of any party to enforce any of that
party's rights against the other party for breach of any of the terms of this
Agreement shall not be construed as a waiver of such rights as to any continued
or subsequent breach.

     14. COST OF LITIGATION. In any action at law or in equity to enforce any of
the provisions or rights under this Agreement,  the  unsuccessful  party to such
litigation,  as determined by the court in a final  judgment or decree,  pay the
successful party or parties all costs,  expenses and reasonable  attorneys' fees
incurred by the successful party or parties (including without limitation costs,
expenses and fees in any appellate  proceedings),  and if the  successful  party
recovers  judgment in any such action or  proceeding,  such costs,  expenses and
attorney's fees shall be included as part of the judgment.

     15.  GOVERNING  LAW.  This  Agreement  shall be governed by the laws of the
State of Utah.
