STOCK OPTION AGREEMENT

         Agreement,  made  as of  December  1,  1998,  by and  between  Pre-Cell
Solutions,  Inc., a Colorado  corporation (the "Company"),  and Thomas E. Biddix

(the "Employee").

         WHEREAS, on December 1, 1998 (the "Grant Date"), the board of directors
authorized the employment of the employee pursuant to the terms of an employment
agreement  dated as of  December  1, 1998,  and the grant to the  employee of an
option (the  "Option")  to  purchase an  aggregate  of  4,000,000  shares of the
authorized  but unissued  common stock of the company,  $.01 par value  ("Common
Stock"),  conditioned upon the Employee's  acceptance thereof upon the terms and
conditions set forth in this Agreement; and

         WHEREAS,  the  Employee  desires to acquire the option on the terms and
conditions set forth in this Agreement;

         IT IS AGREED:

         1. Grant of Stock Option. The Company hereby grants to the Employee the
right and option  ("Option")  to  purchase  all or any part of an  aggregate  of
4,000,000  shares of Common Stock ("Option  Shares") on the terms and conditions
set forth herein. The Option represented hereby is a non-qualified  stock option
not intended to qualify under any section of the Internal  Revenue Code of 1986,
as amended, and is not granted under any plan.

Certain terms used herein, however, are defined under the Plan.

         2. Exercise Price. The exercise price ("Exercise  Price") of the Option
shall be $0.04 per share.

         3. Exercisability. This Option is exercisable, subject to the terms and
conditions of this  Agreement,  one year after the Grant Date.  After the Option
vests,  it shall remain  exercisable for a period of five years from the date of
vesting,  except  as  otherwise  set  forth  in this  Agreement  (the  "Exercise
Period").

         4. Effect of Termination of Employment.

<PAGE>

                  4.1 Termination Due to Death. If Employee's  employment by the
Company  terminates by reason of death, the Option shall become fully vested and
exercisable and may thereafter be exercised by the legal  representative  of the
estate or by the legatee of the Employee  under the will of the Employee,  for a
period of six months from the date of such death or until the  expiration of the
Exercise Period, whichever period is shorter.

                  4.2 Termination Due to Disability. If Employee's employment by
the Company  terminates by reason of  Disability  (as such term is defined under
the  Plan),  the Option  shall  become  fully  vested  and  exercisable  and may
thereafter be exercised by the Employee for a period of six months from the date
of such  termination or until the expiration of the Exercise  Period,  whichever
period is shorter.

                  4.3  Termination  by the Company  Without  Cause and/or Due to
Retirement.  If Employee's employment is terminated by the Company without cause
or due to Normal  Retirement (as such term is defined under the Plan),  then (i)
the  portion  of the  Option  which  has  vested by the date of  termination  of
employment may be exercised by the Employee until the expiration of the Exercise
Period and (ii) the  portion of the Option that will vest within one year of the
date of termination of employment shall become fully vested and may be exercised
by the Employee until the expiration of the Exercise Period.  The portion of the
Option not exercisable  within one year of the date of termination of employment
shall immediately expire.

                  4.4 Other Termination.

                           (1) If Employee's  employment  is terminated  for any

reason other than (i) death, (ii) Disability,  (iii) Normal Retirement,  or (iv)
without cause by the Company, the Option shall expire on the date of termination
of employment.

                           (2)  The  Board  of  Directors,   in  the  event  the

Employee's  employment  is  terminated  for cause,  may require the  Employee to
return to the  Company  the  economic  benefit  of any Option  Shares  purchased
hereunder  by the  Employee  within  the six month  period  prior to the date of
termination. In such event, the Employee hereby agrees to remit to the

                                       2

<PAGE>

Company,  in cash,  an amount  equal to the  difference  between the Fair Market
Value (as such term is defined  under the Plan) of the Option Shares on the date
of termination (or the sales price of such Shares if the Option Shares were sold
during such six month period) and the Exercise Price of such Shares.

         5. Withholding Tax. Not later than the date as of which an amount first
must be  included in the gross  income of the  Employee  for Federal  income tax
purposes with respect to the Option,  the Employee shall pay to the Company,  or
make  arrangements  satisfactory to the Committee  regarding the payment of, any
Federal,  state and local  taxes of any kind  required  by law to be withheld or
paid with respect to such amount  ("Withholding  Tax").  The  obligations of the
Company under the Plan and pursuant to this Agreement shall be conditioned  upon
such  payment or  arrangements  with the Company and the Company  shall,  to the
extent permitted by law, have the right to deduct any Withholding Taxes from any
payment of any kind otherwise due to the Employee from the Company.

         6. Adjustments. In the event of any change in the number of outstanding
shares of Common Stock of the Company  occurring as the result of a stock split,
reverse stock split or stock dividend on the Common Stock, after the Grant Date,
the Company  shall  proportionately  adjust the number of Option  Shares and the
Exercise  Price of the Option.  Any right to acquire a  fractional  Option Share
resulting from adjustments will be rounded to the nearest whole Option Share. If
the Company shall be the surviving  corporation  in any merger,  combination  or
consolidation, this Option shall pertain and apply to the Option Shares to which
the Employee is entitled hereunder, without adjustment. In the event of a change
in the par value of the shares of Common Stock which are subject to this Option,
this  Option  will be deemed to pertain to the  shares  resulting  from any such
change. To the extent that the foregoing adjustments relate to Common Stock, the
adjustments will be made by the Board of Directors whose  determination  will be
final, binding and conclusive.

         7. Method of Exercise.

                                       3

<PAGE>

                  7.1 Notice to the  Company.  The Option  may be  exercised  in
whole or in part by  written  notice in the form  attached  hereto as  Exhibit A
directed to the Company at its principal  place of business  accompanied by full
payment as  hereinafter  provided of the exercise price for the number of Option
Shares specified in the notice and of the Withholding Taxes, if any.

                  7.2 Delivery of Option  Shares.  The Company  shall  deliver a
certificate  for the Option Shares to the Employee as soon as practicable  after
payment therefor.

                  7.3 Payment of Purchase Price.

                           7.3.1  Cash  Payment.  The  Employee  shall make cash

payments by wire transfer,  certified or bank check or personal  check,  in each
case payable to the order of the Company;  the Company  shall not be required to
deliver  certificates  for Option  Shares  until the Company has  confirmed  the
receipt of good and available funds in payment of the purchase price thereof.

                           7.3.2 Stock Payment.  The Board of Directors,  in its

sole discretion,  may allow Employee to use Common Stock of the Company owned by
him to  make  any  required  payments  by  delivery  of  stock  certificates  in
negotiable  form which are effective to transfer good and valid title thereto to
the Company, free of any liens or encumbrances.  Shares of Common Stock used for
this  purpose  shall be valued at the Fair  Market  Value.  Notwithstanding  the
foregoing,  the  Company  shall have the right to reject  payment in the form of
Common Stock if in the opinion of counsel for the  Company,  (i) it could result
in an event of "recapture" under Section 16(b) of the Securities Exchange Act of
1934;  (ii) such shares of Common  Stock may not be sold or  transferred  to the
Company; or (iii) such transfer could create legal difficulties for the Company.

         8.   Nonassignability.   The  Option   shall  not  be   assignable   or
transferable,  except by will or by the laws of descent and  distribution in the
event of the death of the Employee. No transfer of the Option by the Employee by
will or by the laws of descent and  distribution  shall be effective to bind the
Company unless the Company shall have been furnished with written notice

                                       4

<PAGE>

thereof  and a copy of the will  and/or  such other  evidence as the Company may
deem  necessary to establish the validity of the transfer and the  acceptance by
the transferee or transferees of the terms and conditions of the Option.

         9. Accelerated Vesting and Exercisability.  If (i) any person or entity
other than the Company  and/or any officer,  director or  principal  stockholder
(i.e.,  a holder  [beneficially  or of record]  of more than ten  percent of the
Company's  voting stock) of the Company  acquires  securities of the Company (in
one or more  transactions)  having 25% or more of the total  voting power of all
the Company's securities then outstanding and (ii) the Board of Directors of the
Company  does not  authorize or otherwise  approve  such  acquisition,  then the
vesting  periods  of the  Option  shall  be  accelerated  and the  Option  shall
immediately and entirely vest. In such event,  Employee shall have the immediate
right to  purchase  all the Option  Shares,  subject to the  provisions  of this
Agreement.

         10. Company Representations. The Company hereby represents and warrants
to the Employee that:

                           (1) the  Company,  by  appropriate  and all  required
         action,  is duly authorized to enter into this Agreement and consummate
         all of the transactions contemplated hereunder; and

                           (2) the Option  Shares,  when issued and delivered by
         the Company to the Employee in accordance with the terms and conditions
         hereof,   will  be  duly  and   validly   issued  and  fully  paid  and
         non-assessable.

         11.  Employee  Representations.  The  Employee  hereby  represents  and
warrants to the Company that:

                           (1) he is acquiring  the Option and shall acquire the
         Option  Shares  for his own  account  and not with a view  towards  the
         distribution thereof;

                           (2)  he  has  received  a copy  of  all  reports  and
         documents  required to be filed by the Company with the  Securities and
         Exchange Commission pursuant to the Securities Exchange Act of 1934, as
         amended,  within  the last 24  months  and all  reports  issued  by the
         Company to its stockholders;

                                       5

<PAGE>

                           (3) he  understands  that he must  bear the  economic
         risk of the  investment in the Option  Shares,  which cannot be sold by
         him unless they are  registered  under the  Securities Act of 1933 (the
         "1933 Act") or an exemption therefrom is available  thereunder and that
         the Company is under no  obligation  to register the Option  Shares for
         sale under the 1933 Act;

                           (4) in his position with the Company, he has had both
         the  opportunity to ask questions and receive answers from the officers
         and  directors  of the  Company  and all  persons  acting on its behalf
         concerning  the terms and conditions of the offer made hereunder and to
         obtain any additional  information to the extent the Company  possesses
         or may possess such information or can acquire it without  unreasonable
         effort or expense  necessary to verify the accuracy of the  information
         obtained pursuant to clause (ii) above;

                           (5) he is aware  that the  Company  shall  place stop
         transfer  orders with its  transfer  agent  against the transfer of the
         Option Shares in the absence of  registration  under the 1933 Act or an
         exemption therefrom as provided herein; and

                           (6) if, at the time of issuance of the Option Shares,
         the  issuance of such shares  have not been  registered  under the 1933
         Act,  the  certificates  evidencing  the Option  Shares  shall bear the
         following legend:

                      "The  shares  represented  by this  certificate  have been
                      acquired for investment and have not been registered under
                      the  Securities Act of 1933. The shares may not be sold or
                      transferred  in the  absence  of such  registration  or an
                      exemption therefrom under said Act."

         12. Restriction on Transfer of Option Shares.

                  12.1   Anything   in   this    Agreement   to   the   contrary
notwithstanding,  Employee hereby agrees that he shall not sell, transfer by any
means  or  otherwise  dispose  of the  Option  Shares  acquired  by him  without
registration  under  the  1933  Act,  or in  the  event  that  they  are  not so
registered,  unless (i) an exemption from the 1933 Act registration requirements
is available  thereunder,  and (ii) the Employee has  furnished the Company with
notice  of such  proposed  transfer  and the  Company's  legal  counsel,  in its
reasonable opinion, shall deem such proposed transfer to be so exempt.

                  12.2   Anything   in   this    Agreement   to   the   contrary
notwithstanding,  Employee hereby agrees that he shall not sell, transfer by any
means or otherwise dispose of the Option Shares acquired by him (i) prior to six
months after the Grant Date and (ii) except in accordance with Company's policy,
if any,  regarding the sale and  disposition  of  securities  owned by employees
and/or directors of the Company.

contained in this Agreement shall be deemed to confer upon Employee any right to
continued  employment with the Company or any subsidiary  thereof,  nor shall it
interfere in any way with the right of the Company to terminate Employee in

                  1.2 The President may assign to Executive such other executive
duties  for the  Company or any  Affiliate  (as  defined in Section  5.1) as are
consistent with Executive's status as Chief Operating Officer.

                  1.3 Executive  accepts such  employment and agrees to devote a
sufficient  portion  of  his  business  time,  energies  and  attention  to  the
performance of his duties.  Executive shall perform his duties  primarily in and
from the Company's offices located in Melbourne, Florida.

         2.       Compensation and Benefits.

                  2.1  The  Company   shall  pay  to  Executive  a  base  salary
("Salary") at the aggregate rate of $95,000 per annum during the Employment Term
(as such term is defined in Section  3.1,  below).  Executive's  Salary shall be
paid in equal,  periodic  installments,  in accordance with

the Company's  normal  payroll  procedures  and shall be subject to  withholding
taxes and other normal payroll deductions.

                  2.2 The Company may award  Executive a bonus (the  "Bonus") at
the sole  discretion of the Board,  which Bonus shall be  determined  based upon
Executive's performance and the Company's performance generally. Notwithstanding
the foregoing, Executive understands that the Company is not obligated under any
circumstances, to award any such Bonus.

                  2.3 The Company shall annually review Executive's performance.
Based upon such review and such other factors as the Company may  consider,  the
Company  may  determine  to increase  Executive's  salary.  Notwithstanding  the
foregoing,  Executive  understands  that the Company is not obligated  under any
circumstances, to award any such increase in salary.

                  2.4 Executive  shall be entitled to such  medical,  dental and
disability insurance which is no less favorable than generally afforded to other
senior  executives  of the Company,  subject to applicable  waiting  periods and
other conditions.  Executive shall be entitled to four weeks of vacation in each
employment  year and to a reasonable  number of other days off for religious and
personal  reasons.  Executive  acknowledges  that the Company may,  from time to
time, apply for and take out in its own name and at its expense,  life,  health,
disability,  accident or other  insurance,  including  key man  insurance,  upon
Executive  that the  Company may deem  necessary  and  advisable  to protect its
interests  hereunder;  and  Executive  agrees to submit to any  medical or other
reasonable  examination  necessary  for such purpose and to assist and cooperate
with the Company in procuring such insurance; and Executive acknowledges that he
shall have no right, title or interest in or to such insurance.

                  2.5  The  Company  will  pay or  reimburse  Executive  for all
transportation,  hotel and other  expenses  reasonably  incurred by Executive on
business trips and for all other ordinary and reasonable  out-of-pocket expenses
actually  incurred by him in the conduct of the business of the Company  against
itemized  vouchers  submitted  with  respect to any such  expenses  approved  in
accordance with customary procedures.

                  2.6  Simultaneous  with the execution of This  Agreement,  The
Company  will grant  Executive  the option to purchase  3,000,000  shares of the
Company's  common stock,  par value $.01 per share, at an exercise price of $.04
per share (the  "Option").  The Option shall fully vest one year after the grant
date and shall remain exercisable for a period of five years after vesting.  The

                                       2
<PAGE>

Option shall be evidenced by a Stock Option  Agreement  entered into between the
Company and Executive of even date herewith.

         3.       Term and Termination.

                  3.1 The term of this  Agreement  commences  as of  December 1,
1998 and shall continue until December 1, 2001 (the "Employment  Term"),  unless
sooner terminated or extended as herein provided.

                  3.2 If Executive dies during the term of this Agreement,  this
Agreement shall thereupon terminate.

                  3.3 The Company,  by notice to Executive,  may terminate  this
Agreement if Executive  shall fail because of illness or  incapacity  to render,
for six  consecutive  months,  services of the  character  contemplated  by this
Agreement.

                  3.4 The Company, by not less than 30 days notice to Executive,
may  terminate  this  Agreement  without cause at any time. In the event of such
termination the Company shall pay to Executive the salary due Executive pursuant
to  Paragraph  2.1 through  the  Employment  Term as  provided  in Section  3.1.
Notwithstanding such termination, the provisions of paragraph 4 shall survive.

                  3.5 The Company,  by notice to Executive,  may terminate  this
Agreement for cause. As used herein,  "cause" shall include,  but not be limited
to: (a) the refusal or failure by Executive to carry out specific  directions of
the Chief Executive  Officer which are of a material  nature,  or the refusal or
failure by Executive to perform a material part of Executive's duties hereunder;
(b) the commission by Executive of a material breach of any of the provisions of
this  Agreement;  (c) common law fraud or  dishonest  action by Executive in his
relations with the Company or any of its subsidiaries or affiliates, or with any
customer  or  business  contact  of the  Company or any of its  subsidiaries  or
affiliates  ("dishonest" for these purposes shall mean Executive's  knowingly or
recklessly  making of a  material  misstatement  or  omission  for his  personal
benefit);  or (d) the  conviction of Executive of any crime  involving an act of
moral turpitude. Notwithstanding the foregoing, no "cause" for termination shall
be deemed to exist with respect to Executive's  acts described in clauses (a) or
(b) above,  unless the  Company  shall have given  written  notice to  Executive
specifying the "cause" with  reasonable  particularity  and, within ten business
days after such notice, Executive shall not have cured or eliminated the problem
or thing giving rise to

                                       3
<PAGE>

such "cause;" provided,  however,  that a breach of any provision of clauses (a)
or (b) above, involving the same or substantially similar actions or conduct for
which the Company  previously  gave notice of  termination  and with  respect to
which,  Executive  satisfactorily  cured,  shall be grounds for  termination for
cause  without any  additional  notice from the  Company.  Notwithstanding  such
termination, the provisions of paragraph 4 shall survive.

                  3.6 The  Executive,  by notice to the Company,  may  terminate
this Agreement if the Company materially  breaches any of the provisions of this
Agreement.  Notwithstanding the foregoing,  the Executive shall not have grounds
for termination  unless Executive shall have given written notice to the Company
specifying the breach with reasonable  particularity  and, within ten days after
such notice, the Company shall not have cured or eliminated the problem or thing
giving rise to such breach; provided, however, that a breach of any provision of
this Agreement  involving the same or  substantially  similar actions or conduct
for which the Executive  previously  gave notice of termination and with respect
to which, the Company satisfactorily cured, shall be grounds for termination for
cause  without  any  additional  notice  from  the  Executive.  In the  event of
termination  by  Executive  under this  Section  3.6,  the Company  shall pay to
Executive the Salary due Executive  pursuant to paragraph 2.1 hereof through the
Employment Term. Notwithstanding such termination, the provisions of paragraph 4
shall survive  termination if the Company  continues to pay Executive the Salary
as provided in the immediately preceding sentence.

         4.       Protection of Confidential Information; Non-Competition.

                  4.1      Executive acknowledges that:

                           (a) As a result of his  employment  with the Company,
Executive  will  obtain  secret  and  confidential  information  concerning  the
business of the Company  and/or its  subsidiaries  and  affiliates  (referred to
collectively  in  this  paragraph  4  as  the  "Company"),   including,  without
limitation,  financial information,  designs and other proprietary rights, trade
secrets and "know-how," customers and sources ("Confidential Information").

                           (b) The Company will suffer  substantial damage which
will be difficult to compute if,  during the period of his  employment  with the
Company or thereafter, Executive should divulge Confidential Information.

                           (c) The  provisions of this  Agreement are reasonable
and necessary for the protection of the business of the Company.

                                       4
<PAGE>

                  4.2  Executive  agrees  that he will not at any  time,  either
during the term of this Agreement or thereafter, divulge to any person or entity
any  Confidential  Information  obtained  or  learned  by him as a result of his
employment with, or prior retention by, the Company, except (i) in the course of
performing  his  duties  hereunder;  (ii)  with the  Company's  express  written
consent;  (iii) to the extent that any such  information is in the public domain
other  than  as a  result  of  Executive's  breach  of any  of  his  obligations
hereunder;  or (iv) where  required to be disclosed by court order,  subpoena or
other  government  process.  If Executive  shall be required to make  disclosure
pursuant to the provisions of clause (iv) of the preceding  sentence,  Executive
promptly,  but in no event more than 72 hours after  learning of such  subpoena,
court order, or other government process,  shall notify, by personal delivery or
by  electronic  means,  confirmed  by mail,  the Company  and, at the  Company's
expense,  Executive  shall:  (a) take all reasonably  necessary and lawful steps
required by the  Company to defend  against the  enforcement  of such  subpoena,
court order or other government process, and (b) permit the Company to intervene
and  participate  with counsel of its choice in any  proceeding  relating to the
enforcement thereof.

                  4.3 Upon  termination  of his  employment  with  the  Company,
Executive will promptly  deliver to the Company all memoranda,  notes,  records,
reports,  manuals,  drawings,  blueprints  and other  documents  (and all copies
thereof)  relating to the  business of the Company and all  property  associated
therewith,  which he may then  possess  or have  under  his  control;  provided,
however, subject to Executive's obligations under this Section 4, that Executive
shall be entitled to retain  copies of such  documents  reasonably  necessary to
document his financial relationship (both past and future) with the Company.

                  4.4 If  Executive  commits a breach,  or threatens to commit a
breach,  of any of the  provisions  of Sections  4.2, the Company shall have the
right and remedy:

                           (a)  to  have  the   provisions  of  this   Agreement
specifically  enforced  by  any  court  having  equity  jurisdiction,  it  being
acknowledged  and agreed by Executive that any such breach or threatened  breach
will cause  irreparable  injury to the Company and that money  damages  will not
provide an adequate remedy to the Company; and

                           (b) to require  Executive to account for and pay over
to the Company all monetary damages suffered by the Company as the result of any
transactions constituting a breach of any of the provisions of Sections 4.2, and
Executive hereby agrees to account for and pay over such damages to the Company.

                                       5
<PAGE>

                  Each of the rights and remedies enumerated in this Section 4.4
shall be independent of the other, and shall be severally enforceable,  and such
rights  and  remedies  shall be in  addition  to,  and not in lieu of, any other
rights and remedies available to the Company under law or equity.

                  In connection with any legal action or proceeding  arising out
of Section  4.4,  the  prevailing  party in such action or  proceeding  shall be
entitled to be reimbursed by the other party for the reasonable  attorneys' fees
and costs incurred by the prevailing party.

                  4.5 If  Executive  shall  violate any  covenant  contained  in
Section 4 the  duration  of such  covenant so  violated  shall be  automatically
extended for a period of time equal to the period of such violation.

                  4.6 The  provisions  of this  paragraph  4 shall  survive  the
termination of this Agreement for any reason.

         5.       Definitions.
