Item 1.   Business

General
- -------

     As of June 30, 1997, Pro-Dex, Inc. (or the "Company") or was
the parent company of four operating subsidiaries, Biotrol Inter-
national,Inc. ("Biotrol"), Challenge Products,Inc. ("Challenge"),
Micro  Motors, Inc.  ("Micro"),  and Oregon  Micro  Systems, Inc.
("OMS").  Biotrol manufactures and distributes  infection control
products for the dental industry. Challenge manufactures fluoride
and  related  products  for preventive dentistry.  Micro, a manu-
facturer  of miniature  pneumatic  motors,  was  merged with  and
into a wholly owned subsidiary of the Company on July  26,  1995.
Micro also manufactures and markets a complete line of hand-pieces
for  the  dental  industry.  On  July  26, 1995, the Company also
acquired  all  the  outstanding  stock  of  OMS.  OMS designs and
manufactures multi-axis circuit boards used to control the motion
of servo and stepper motors, predominantly  for the computer chip
manufacturing industry.

     During the year ended June 30, 1997, the Company disposed of
its Pnu-Light operation by unwinding the transaction pursuant  to
which it acquired Pnu-Light Tool Works, Inc. ("Pnu-Light").   The
Company also sold substantially all of the assets, excepting only
the  accounts receivable and certain leasehold interests, of  its
Pro-Dex  Management, Inc. ("DCM") subsidiary.  See  "Divestitures
During Year Ended June 30, 1997".
     
     On   May   25,  1994,  the  shareholders  of  the  Company's
predecessor  approved a Plan of Reorganization and  Agreement  of
Merger  pursuant  to  which  the Company  changed  its  state  of
incorporation to Colorado.

Acquisitions History
- --------------------

      On  July  26, 1995 the Company acquired all the issued  and
outstanding  stock  of  Oregon Micro  Systems,  Inc.,  an  Oregon
corporation   ("OMS")  from  Mr.  L.  Wayne  Hunter,   the   sole
shareholder  of OMS.  In addition to the OMS stock,  the  Company
also  acquired from Mr. Hunter related assets identified  as  two
letters  patent for the design of OMS' multi-axis motion  control
circuit boards.  OMS provides the design and manufacture of multi
axis  circuit  boards  to  control  the  motion  of  motors  used
predominantly  in  medical testing equipment  and  computer  chip
manufacturing machinery.  The total purchase price paid  for  the
OMS  stock  and  related  assets  was  approximately  $6,700,000,
including  a post closing adjustment, all of which for accounting
purposes has been recorded under the purchase method.
     
     Mr.  Hunter  and the Company also entered into a  consulting
and   non-competition  agreement  pursuant  to  which,   in   the
aggregate, the Company will pay Mr. Hunter $1,000,000  over  five
(5)  years.  The parties allocate approximately $2,700,000 of the
purchase  price  to the patents.  The balance  of  $4,000,000  is
allocated  to  the stock of OMS.  The underlying assets  and  net
book  value of OMS, not including any intellectual property,  was
approximately  $3,817,000.  See "Item 12 - Certain  Relationships
and Related Party Transactions."
     
     The  Company obtained a five (5) year term loan from  Finova
Capital  Corporation ("Finova") and borrowed  $500,000  from  Air
Techniques,  Inc., a Delaware corporation ("Air  Techniques")  to
finance portions of the acquisition price and related acquisition
costs.   The  remaining principal of the acquisition  loans  from
Finova  and  Air Techniques has since been repaid  with  proceeds
from  a  loan from Harris Bank and Trust, N.A., which the Company
obtained  on  July 26, 1996.  Prior to repayment of  such  Finova
loan,  the Company was required to pay interest at prime plus 3.5
percent  plus  an  additional annual 5% profit participation  fee
calculated  on the outstanding loan balance at the  beginning  of
each  year.   Pursuant to the loan agreement with Air Techniques,
such lender was issued warrants to acquire an aggregate of 26,000
shares of the Company, exercisable at the loan date market price,
with  such warrants and underlying shares restricted and legended
in  accordance with the registration requirements of the  federal
securities  laws.   Also pursuant to the  loan  agreement  and  a
guaranty  of the Air Techniques loan entered into by Professional
Sales Associates, Inc. ("PSA"), that firm was issued warrants  to
acquire  13,000 restricted shares of the Company's common  stock,
exercisable at the loan date market price. Three of the Company's
directors,  including its Chairman, are directors  of  PSA.   See
"Item  6  -  Management Discussion and Analysis -  Liquidity  and
Capital  Resources"  and  "Item 12 - "Certain  Relationships  and
Related Party Transactions."

     Also  on  July 26, 1995, Micro Motors, Inc. ("Micro Motors")
was merged with and into Micro, which thereafter changed its name
to  Micro  Motors,  Inc.,  pursuant to a Merger  Agreement  among
Micro,  Micro  Motors,  the five Micro Motors  shareholders  (the
"Micro  Shareholders") and the Company.  In connection  with  the
statutory  merger of Micro Motors with and into Micro, the  Micro
Shareholders were issued 3,350,000 shares of the Company's common
stock  in exchange for all of their shares of Micro Motors.   The
price  of  the  Company's stock at the time of the  exchange  was
$2.75  per  share, making the initial acquisition cost  of  Micro
$9,212,500.   For  accounting purposes the transaction  has  been
recorded  under the purchase method.  On February 29,  1996,  the
Company's  shareholders approved conversion of 26,272 options  to
acquire  Micro Motors shares, granted prior to the  merger  under
the Micro Motors Stock Option Plan, to options to acquire 591,120
shares  of  the  Company's common stock under the Company's  1994
Stock  Option  Plan.   Micro develops and  manufactures  patented
miniature pneumatic motors and dental hand-pieces.  Prior to  the
merger  transaction,  the former Chairman of  Micro  Motors,  Mr.
Ronald  G. Coss, entered into an agreement to terminate his  long
term employment contract with Micro Motors, Inc., for the sum  of
$677,400  payable  over five years, at 11%  interest  per  annum.
Also, pursuant to the merger, Mr. Coss executed a non-competition
agreement with the Company for consideration in the amount of  $1
million  over  five years, with payment commencing in  the  sixth
year after closing.  Mr. Coss now serves as Vice Chairman of  the
Company.  See "Item 12 - Certain Relationships and Related  Party
Transactions."

     On  May  11,  1996, the Company and its newly formed  wholly
owned  subsidiary,  Pnu-Light,  acquired  substantially  all  the
assets of Pnu-Light Tools, including a letter patent relating  to
pneumatic  light mechanisms to be used in conjunction with  hand-
tools  (the  "Patent"), from Pnu-Light Tools  and  Mr.  Marty  J.
Anderson,   an  individual  resident  of  Missouri  ("Anderson"),
pursuant to an Asset Purchase Agreement dated May 11, 1996  among
the  Company,  Pnu-Light, Pnu-Light Tools and Mr.  Anderson  (the
"Asset Purchase Agreement").  The assets of Pnu-Light Tools  were
acquired  by  the  Company  and Pnu-Light  subject  to  specified
outstanding   liabilities  of  Pnu-Light  Tools.    The   initial
consideration  for  acquisition of  assets  of  Pnu-Light  Tools,
including  the Patent, was issuance of 368,483 restricted  shares
of  the  Company's common stock, valued at $5.63 per  share,  the
market  price  on the transaction date.  Additional consideration
for  acquisition  of  assets of Pnu-Light  Tools  is  payable  by
issuance  of  additional stock, based upon an interim calculation
as  of December 31, 1997, and a final calculation as of June  30,
1999.   The  total purchase price is to equal five (5) times  the
net  after tax earnings of the Pnu-Light Subsidiary for the  year
ending  June  30,  1999,  with a minimum total  consideration  of
$4,000,000 giving credit against such minimum for (a) the greater
of  (i)  the  fair market value of the Company's stock previously
issued  as consideration, as of the date issued or (ii) the  fair
market  value  of  the  Company's  stock  previously  issued   as
consideration,  as  of  June 30, 1999, (b) Patent  related  costs
subsequent  to  closing,  (c) excess accounts  payable,  and  (d)
research  and  development  costs incurred  within  120  days  of
closing.  In addition, the Company, at the Company's sole option,
may  unwind the transaction at any time prior to payment of final
consideration  as of June 30, 1999, provided that  the  value  of
total  consideration payable at 5 times net  after  tax  earnings
shall  not then exceed $4,000,000.  The Company has recorded  the
net  assets  acquired  at  the present value  of  the  estimated,
adjusted minimum purchase price of $3,070,000, using the purchase
method   of   accounting   and  reflecting   therein   additional
consideration  payable pursuant to the Asset Purchase  Agreement.
The  excess  of  the  total acquisition cost of  Pnu-Light  Tools
assets  over  the  fair  value  of the  net  assets  acquired  of
approximately $1,100,000 is being amortized over a 15-year period
by the straight-line method.  See "Divestitures During Year Ended
June 30, 1997."

Divestitures During Year Ended June 30, 1997
- --------------------------------------------

On  April  25, 1997, the Company completed the unwinding  of  its
previous acquisition of the assets of Pnu-Light, including United
States   Patent   No.  5,267,129  entitled  "Pneumatic   Lighting
Apparatus."    The  decision  of  the  Board  of  Directors   was
previously  announced in February 1997.  The anticipated  synergy
between  Pro-Dex' Micro Motors subsidiary and Pnu-Light  did  not
meet  expectations   and, in accordance with procedures contained
in  the  Pnu-Light Asset Purchase Agreement, Martech,  Inc.  (the
surviving  successor of Pnu-Light Tool Works, Inc. reconveyed  to
the  Company 368,483 shares of the Company common stock that were
originally issued to Martech, Inc. in May, 1996.

     The Company,in exchange for the 368,483 shares, assigned the
Pneumatic Lighting Apparatus Patent to Martech, Inc. subject to a
non-exclusive,  fully paid, worldwide license to  the  technology
and the proprietary information which are retained by Pro-Dex.

     On  June  11,  1997, the Company completed the sale  of  the
assets and business, exclusive of accounts receivable, of Pro-Dex
Management,   Inc.,   the  Company's  dental  clinic   management
subsidiary in California ("DCM").  The effective date of sale was
May  31, 1997.  The decision of the Board of Directors to explore
the  feasibility of a sale of the subsidiary was discussed by the
Company in previous reports.  The sale of assets transaction  was
made  with  Professional Dental Management, L.L.C., a  California
limited  liability  company ("PDM").  Dr. M. Larry  Kyle  is  the
managing member of PDM and prior to the sale was president of DCM
and  a  member  of the Company's Board.  See "Item 12  -  Certain
Relationships and Related Party Transactions."  The terms of  the
sale  provide  that PDM assume DCM liabilities  of  approximately
$670,000 in exchange for the inventory and equipment of DCM.  DCM
retains   its   accounts  receivable  in  the   net   amount   of
approximately  $1,800,000  which  will  be  collected,  with  the
assistance of PDM, over the ensuing 12 to 24 months.  The  losses
from  operations of DCM have been reported by the Company on  the
basis  of  discontinued operations since the Company's  Board  of
Directors announcement of the intention to sell the business  and
assets  of  DCM.  If the allowance for doubtful accounts  is  not
adequate  to insure  the realization of the net amount  of  DCM's
receivables, additional losses from discontinued operations could
occur in future years.

Products Offered by Biotrol
- ---------------------------

     Biotrol   is   a   dental   products  distribution   company
specializing in infection control products and preventive  dental
products.  Biotrol believes that the products offered by  it  can
be  used effectively as an operatory infection control system  to
minimize  cross-contamination by potentially infectious organisms
in  the  dental  operatory.  Biotrol's infection  control  system
includes  five  categories  of  products:  surface  cleaners  and
disinfectants;  immersion cleaners and  disinfectants;  a  dental
vacuum  line  cleaner/disinfectant;  barriers;  and  a  line   of
preventative   dental  products  manufactured  for   Biotrol   by
Challenge  under  the  "Perfect ChoiceTM" label.  These  products
include  fluoride  gels  and rinses in  addition  to  prophylaxis
pastes and related preventive dentistry products.
     
     Biotrol   has  entered  into  a  marketing  agreement   with
Challenge,  whereby it markets Challenge's branded products.   In
the   opinion  of  management,  this  inter-corporate   marketing
agreement does not undercut Biotrol's ability to enter into other
non-exclusive  marketing  agreements.   Over  fifty-nine  percent
(59%)  of  Biotrol sales are attributable to four customers  with
whom  Biotrol has maintained longstanding relationships.  Biotrol
has  no  plans to discontinue these relationships,  nor  does  it
believe  these  customers  have any plans  to  discontinue  their
relationship  with Biotrol.  Any material adverse change  in  the
relationship  with  these  four  customers  may  be   financially
detrimental to Biotrol.

     Biotrol   considers  its  relationships  with  its   various
suppliers and manufacturers to be excellent.  It does not  intend
to  terminate  any  relationship  at  this  time,  nor  does  its
management  believe  any relationships will be  terminated  by  a
supplier or manufacturer.  Biotrol holds no franchises and has no
exclusive   arrangements   with   any   of   its   suppliers   or
manufacturers.   Should  a  product become  unavailable  for  any
reason from a significant vendor, such unavailability could  have
a negative impact on Biotrol's business.

     At  the present time, Biotrol is usually able to fill orders
within  forty-eight hours.  During the year ended June 30,  1997,
Biotrol  continued  to maintain its record for improved  customer
service and turn-around time.  At June 30, 1997, Biotrol  had  no
order  backlog,  and had virtually no backlog at June  30,  1996.
Biotrol  does  not typically experience seasonal fluctuations  in
its orders.
     
Products Offered by Challenge
- -----------------------------

     Challenge is a manufacturer of products used by dentists for
the  prevention of dental disease.  The majority of its  business
is  the  formulation and manufacture of gels, pastes, and  rinses
for  in-office and home treatments for the prevention  of  dental
diseases.   Its products are sold under the Challenge  labels  of
"Perfect ChoiceTM", "Dual-XTM", "DentaliteTM",  and "Prophy  Gems
TM", which  are  marketed  under  the  "Perfect  ChoiceTM" label.
Biotrol markets challenge  products through the  current  Biotrol
sales force and distributors.
     
     Forty-three   percent  (43%)  of  Challenge   products   are
formulated,  packaged,  and sold under private  label  agreements
with  other  dental  manufacturers and  distributors.   Two  such
manufacturers/distributors represent a significant percentage  of
Challenge's private label sales, however, these relationships are
longstanding  and  Challenge has no plans  to  discontinue  these
relationships, nor does it believe that these customers have  any
plans  to  discontinue their relationships with  Challenge.   Any
material adverse change in the relationships with either  of  the
two customers representing significant percentages of Challenge's
private label sales may be financially detrimental to Challenge.
     
     Sixty-nine percent (69%) of Challenge's revenues are derived
from sales to its two largest customers.  The largest portion  of
such  revenues,  constituting fifty-one percent  (51%)  of  total
sales are to Biotrol, under Challenge's marketing agreement  with
Biotrol.   Management considers that the inter-company nature  of
the  relationship with Biotrol affords somewhat greater  security
of  continuity of relationship than could ordinarily be expected.
Nevertheless,  if any material adverse change were  to  occur  in
Challenge's  volume of business with either of  its  two  largest
customers,   such  change  may  be  financially  detrimental   to
Challenge.

     Challenge  usually  fills orders for  its  branded  "Perfect
ChoiceTM" and "Prophy GemTM"  products  within  forty-eight hours
and carries little backlog, enabling it to  provide  a  level  of
customer  service,  which  enhances marketing  of  the  products.
Unlike  the  branded  products, private label  customers  usually
anticipate a 30 to 60-day lead-time for the delivery of  products
to  them.   As  of  June 30, 1997, Challenge  had  a  backlog  of
$129,000,  the largest proportion of which related to  timing  of
orders for private label products not due for immediate shipment.
At  June 30, 1996, Challenge had a backlog of $88,000.  Challenge
does  not  typically  experience  seasonal  fluctuations  in  its
orders,  and  expects to fill all its orders during  the  current
fiscal year.

DCM - Dental Center Operations
- ------------------------------

     Pro-Dex  provided dental services through its DCM subsidiary
from  1978  until substantially all of the assets, excepting  the
accounts  receivable  and certain leasehold  interests,  of  that
subsidiary  were  sold effective May 31, 1997,  pursuant  to  the
direction  of the Board of Directors and as previously disclosed.
The  Company has reported the financial statements of  DCM  as  a
"discontinued operation" since July 1, 1995.  Prior to the  sale,
dental services were provided by independent dentists contracting
with  DCM  to operate in the facilities leased by DCM  using  DCM
management  services.   DCM  management  services  included   the
establishment  of  business procedures and  the  development  and
implementation  of  promotional  activities.   DCM  equipped  and
staffed  the dental offices to facilitate the practice of general
and orthodontic dentistry.  Dentists directed all treatment plans
and maintained control over all services provided in each office.
Each  dentist  contracting  with DCM  was  licensed  to  practice
dentistry  in  California.  See "Divestitures During  Year  Ended
June 30, 1997".
     
Products Offered By Micro Motors
- --------------------------------

     Micro  manufactures  miniature  pneumatic  motors  used   in
dental,  medical  and  industrial devices.   In  addition,  Micro
manufactures  and  distributes a complete line  of  dental  hand-
pieces   for  the  dentist  and  hygienist.   Micro's  industrial
products  are  sold directly to original equipment manufacturers.
The  branded hand-piece line is sold to dental distributors,  who
in  turn market directly to the dentist.  Micro products are sold
under the trademarks  "DynatorqTM",  "DynaproTM",   "DynaliteTM",
"DynasurgTM",  and "Micro HandpieceTM".
     
     Seventy-three percent (73%) of Micro sales in the year ended
June  30, 1997 were accounted for by sales of dental hand-pieces.
Such  private label and branded hand-pieces are sold to  original
equipment   manufacturers  and  under  an   exclusive   marketing
agreement   by   the   Company's  Biotrol   International,   Inc.
subsidiary.  Previously, Micro Motors handpieces were marketed by
Professional  Sales Associates, Inc. ("PSA"), a  firm  for  which
three of the Company's directors are directors.  See "Item  12  -
Certain Relationships and Related Party Transactions."

     Approximately twenty-two (22%) of Micro sales  in  the  year
ended  June  30, 1997, consisted of sales of miniature  pneumatic
motors  for industrial and medical use.  Such motors are marketed
through an independent pneumatic distribution network.

     At  the  present time, Micro is usually able to fill  orders
within sixty (60) days.  At June 30, 1997, Micro had a backlog of
orders of approximately $3,122,000, which it believed to be firm.
At  June  30,  1996,  Micro had a backlog of  approximately  $1.9
million.   Micro  expects to fill all of its' backlog  of  orders
during  the  current  fiscal  year.   Micro  does  not  typically
experience seasonal fluctuations in its orders.

Products Offered by OMS
- -----------------------

     OMS  designs and manufactures multi-axis circuit  boards  to
control  the  motion  of  motors used  predominantly  in  medical
testing equipment and computer chip manufacturing machinery.  OMS
markets  its  multi-axis  circuit boards  through  outside  sales
representatives.  For the present, OMS' products  are  profitably
marketed  at prices, which compare favorably with any alternative
products.   As  in any high-technology area, it is important  for
OMS  to  continue development efforts to achieve continued market
acceptance.   In this respect, OMS has benefited from  consulting
services provided in the year ended June 30, 1996 and 1997 by Mr.
Hunter,  the  former  sole  shareholder  of  OMS.   Mr.  Hunter's
consulting  agreement  provides that the  hours  required  to  be
committed to consulting services for the benefit of OMS reduce in
the  year  ending June 30, 1997.  Mr. Hunter continues to  assist
OMS  and  the  Company is confident that the product  development
group  in  place  at OMS will continue to enable OMS  to  compete
effectively.   See "Item 12 - Certain Relationships  and  Related
Party Transactions."

     OMS'  two largest customers account for thirty-three percent
(33%) of its sales, with the largest of such customers accounting
for twenty-three percent (23%) of sales.  These relationships are
well   established.   OMS  has  no  plans  to   discontinue   the
relationships, and has no reason to believe that these  customers
have  any  plans  to  discontinue their relationships  with  OMS.
Nevertheless,  any  material adverse change in the  relationships
with  any  customer representing significant percentages  of  OMS
sales may be financially detrimental to OMS.

     At  the present time, OMS is usually able to fill its orders
within twenty-four hours.  At June 30, 1997, the backlog for  OMS
was  approximately $697,000, as compared to $634,000 as  of  June
30,   1996.    OMS   does   not  typically  experience   seasonal
fluctuations  in  its orders, although there are fluctuations  in
demand  resulting  from cyclical activity in  the  industries  it
serves.

Certain  products manufactured and distributed by  the  Company's
subsidiaries  are  undifferentiated  in  nature  from   competing
products  offered  by  several  other  large  manufacturers   and
distributors.  Intensified competition in the future  may  result
in  price  reductions, reduced revenues and profit  margins,  and
loss  of market share, which would adversely affect the Company's
business,   consolidated  results  of  operations  and  financial
condition.

Research and Development
- ------------------------

      The  Company  has  a  number of  research  and  development
programs  in  place  at  its various subsidiaries.   The  Company
considers  these product development programs to be of importance
in  both  maintaining  and improving its  market  position.   The
amounts spent on research and development activities in 1996  and
1997 were approximately $ 913,875 and $ 1,092,006, respectively.
     
Employees
- ---------

     At June 30, 1997, the Company had approximately 138 full and
part-time employees (excluding independent contractors).  At that
time,   4   full-time  employees  were  assigned   to   corporate
headquarters, and devoted substantially all of their time to  the
operations  of the Company.  Challenge employed approximately  15
persons,  Biotrol  employed approximately 32 persons,  and  Micro
employed  69  persons  as  of June 30,  1997.   OMS  employed  18
individuals, 15 full-time and 3 part-time.
     
     Employees  of  the  Company  have  not  entered   into   any
collective  bargaining agreements with the Company.  The  Company
considers its relations with its employees to be good.

Employee Retirement Plan
- ------------------------

     Effective January 1, 1996, the previously "frozen"  employee
retirement  plan  which  had been in  place  at  Micro  prior  to
acquisition by the Company (the "OMS Plan") was converted to  the
Pro-Dex, Inc. 401(k) Employee Retirement Plan (the "401(k)  Plan"
or  the "Plan").  The 401(k) Plan was adopted by the Company  for
the  benefit of employees of the Company, and all four  operating
subsidiaries.   All  amounts  in the  former  plan  allocated  or
accounted for as being for the benefit of any employee have  been
preserved in such employee's account under the 401(k) Plan.   The
OMS   plan  was  frozen  at  the  time  of  the  acquisition  and
subsequently  merged into the Plan.  For purposes  of  compliance
with   the  Employee  Retirement  Income  Security  Act  of  1974
("ERISA"),  the Company is the Plan Administrator for the  401(k)
Plan,  and  uses Massachusetts Mutual Insurance to assist  it  in
administering the Plan.  All employee contributions to  the  Plan
vest  upon contribution.  Company contributions to the Plan  vest
in   accordance  with  a  six-year  schedule  from  the  date   a
participant  is  first  employed by the Company  or  any  of  its
subsidiaries.  During the year ended June 30, 1997, the Company's
contribution with respect to the 401(k) Plan was set at  $35,156,
a portion of which will have been actually paid in following year
end,  in  accordance  with ERISA standards.   The  terms  of  the
Company's  401(k)  Plan  require  the  Company  to  make  a  Plan
contribution,   on  a  matching  basis,  of   25%   of   employee
contributions,  on  an  annual  basis.   The  Company   currently
anticipates that approximately $45,000 may be contributed to  the
Plan for the year ending June 30, 1998.

     In   1993,  Micro  Motors  established  an  Employee   Stock
Ownership  Plan (ESOP) whose shares in Micro Motors, upon  merger
of Micro Motors with and into Micro were exchanged for restricted
shares of the Company's common stock.  No contributions were made
to  the ESOP in the year ended June 30, 1996.  On July 26,  1996,
the   ESOP  became  eligible  to  exercise  certain  demand   and
concurrent registration rights with respect to the ESOP's  shares
in  the  Company.  Demand registration rights, which would  have,
expired  if  not  exercised prior to July  26,  1997,  have  been
extended  by  agreement  and due to expire  July  26,  1999,  and
concurrent registration rights expire July 26, 2000.

Government Regulations
- ----------------------

     The manufacture and distribution of dental products, such as
the  Micro  dental  hand-piece, the  infection  control  products
marketed by Biotrol, the dental prophylaxis products manufactured
by  Challenge and the provision of dental services  by  DCM,  all
must  be considered to be heavily regulated businesses.  A number
of  state  and federal regulatory bodies, including state  dental
boards, the Environmental Protection Agency ("EPA"), and the Food
and  Drug  Administration ("FDA") have substantial  authority  to
regulate  the  Company's businesses.  The statutes,  regulations,
administrative orders, and advisories, which affect the Company's
businesses,  are extremely complex and subject to diverse,  often
conflicting, interpretations.  While the Company's management and
management  of each of the Company's operating subsidiaries  make
every effort to maintain full compliance with all applicable laws
and  regulations, the Company is unable to eliminate  an  ongoing
risk  that  one  or more of its activities may at some  point  be
determined  to  have been non-compliant.  The penalties  of  non-
compliance   could  range  from  an  administrative  warning   to
termination  of  a  portion of the Company's business.   Further,
even  if  the  Company is subsequently determined to  have  fully
complied  with  applicable  law  or  regulation,  its  costs   in
achieving  such a determination and intervening loss of  business
could  adversely  affect  or  even terminate  a  portion  of  the
Company's business.  Further, a change in regulations at any time
may   have   an  adverse  effect  on  the  Company's  operations.
Notwithstanding  the  risks inherent in  the  Company's  business
sectors,   management  believes  that  each  of   the   Company's
subsidiaries  has  deservedly  enjoyed  a  good  reputation   for
compliance with applicable regulations.

     Several  of  Biotrol's products fall under the Environmental
Protection  Agency's (EPA) jurisdiction and are  registered  with
the EPA.  The Food and Drug Administration (FDA) has jurisdiction
over  Biotrol  products that are considered  medical  devices  or
drugs.   Both EPA and FDA have broad enforcement power to  recall
and prohibit the sale of non-complying products.  As is common in
the  industry,  certain of Biotrol's products and  processes  has
been   periodically   the   subject  of   routine   reviews   and
investigations  by  the EPA and FDA.  Although  certain  products
have been subject to action by the EPA in the past, those actions
were  resolved  to the satisfaction of Biotrol's management,  and
without  recall  or  other interference with  the  operations  of
Biotrol.   While  the  Company's  management  is  confident  that
Biotrol  products and processes fully comply with all  applicable
law  and regulations, the Company is unable to predict the future
outcome  of  any  such  investigation  or  review,  pending   its
completion.   Management  believes that Biotrol  follows  Current
Good Manufacturing Practices (CGMP).
     
     The Food and Drug Administration (FDA) has jurisdiction over
Challenge products that are considered medical devices or  drugs.
As noted above, the FDA has broad enforcement power to recall and
prohibit  the sale of non-complying products.  No claim has  been
made  to date by FDA against Challenge or any of its products  or
processes.   Nevertheless, as is common in the industry,  certain
of  Challenge  products and processes has  been  the  subject  of
routine   reviews  and  investigations.   While   the   Company's
management  is  confident that Challenge products  and  processes
fully comply with applicable law and regulations, the Company  is
unable  to  predict  the  outcome of any  such  investigation  or
review,   pending  its  completion.   Management  believes   that
Challenge follows Current Good Manufacturing Practices (CGMP).

     Micro's  dental hand-pieces are currently not  regulated  by
the  FDA  as  medical devices.  There continues  to  be  internal
review  within  the  FDA  regarding the  scope  of  the  agency's
authority  to  regulate dental equipment such  as  Micro's  hand-
pieces.   Should  the FDA develop regulations  governing  Micro's
products,  Micro intends to comply fully with all applicable  law
and  regulations.   Micro's processes involve  certain  materials
subject  to regulation by the EPA, and Micro management  believes
that   it  has  taken  all  required  measures  to  comply   with
regulations regarding handling and disposition of such materials.
Management believes that Micro follows Current Good Manufacturing
Practices (CGMP).
     
     Management  believes  that  the  processes,  materials   and
products of OMS' business in the manufacture and distribution  of
multi-axis  circuit  boards is conducted in a  manner  consistent
with  EPA  regulations governing disposition of industrial  waste
materials.    Although  the  semi-conductor  and  computer   chip
industries  are  significantly impacted by  the  EPA  regulations
applicable  to the processes and materials used in production  of
computer  chips and computer chip components, OMS management  has
undertaken  measures where possible to reduce  OMS'  exposure  to
risk  of  non-compliance.  Most significantly, OMS acquires  pre-
manufactured computer chips as platforms upon which to place  OMS
technology.  While the Company's management is confident that OMS
products  and  processes  fully comply with  applicable  law  and
regulations, the Company is unable to predict the outcome of  any
investigation  or  review which may in the future  be  undertaken
respecting OMS or its products or processes.  Management believes
that OMS follows Current Good Manufacturing Processes (CGMP).
     
Patents, Trademarks and Licensing Agreements
- --------------------------------------------

     The  Company currently holds letters patent relating to  the
multi-axis motion control circuit boards manufactured by OMS  and
to   the  prophy  ring  technology  utilized  by  Challenge.   In
addition,  Micro holds letters patent relating to  its  miniature
pneumatic motor's products. Patents held by the Company and Micro
Motors have varying expiration dates,  none of which  will expire
earlier  than  2005.     Further,  the  Company  has  retained  a
non-exclusive,  paid up, worldwide license to the letters  patent
relating  to  the  pneumatic light for incorporation  into  hand-
tools.   The Company has conducted limited review of the  letters
patent acquired in connection with the OMS and Micro acquisitions
and  believes  that  the use of such letters  patent  is  neither
infringed upon by any third party, nor infringes on any prior art
of  any  third  party.   Notwithstanding the  limited  review  of
letters  patent  relating to the Micro and  OMS  businesses,  the
Company is unable to assess the validity, scope, or defensibility
of  the  foregoing letters patent.  Any challenge to or claim  of
infringement  relating  to  the Company's  letters  patent  could
adversely affect the Company's Micro and OMS operations.
     
     Prior  to  the  Company's acquisition of OMS,  OMS  and  its
founder entered into a world wide, fully paid limited use license
of  certain letters patent with Abbott Laboratories.  The founder
of OMS has agreed to indemnify the Company for any further duties
to  be  performed  in  connection  with  the  license  to  Abbott
Laboratories, which are the obligation of such individual as sole
recipient of related royalties.

     The   Company's  Micro  subsidiary  has  certain  trademarks
relating  to  its miniature pneumatic motors products,  including
"DynatorqTM", "DynaproTM", "DynaliteTM", "DynasurgTM", and "Micro
HandpieceTM". Challenge Products Inc.'s products are  sold  under
the  trade name  "DentaliteTM", in both  the  United  States  and
Canada.    In  addition,  Challenge  offers  its  new   line   of
preventative  dental  products  under  its   "Perfect   ChoiceTM"
tradename.   Challenge  also markets its "Prophy  GemsTM"  dental
prophylaxis  product  under its "Perfect ChoiceTM"  trademark  in
both the United States and Canada.

     Except  as  noted  the  Company has  not  entered  into  any
licensing or franchising agreements and has no present  plans  to
do so.
     
Item 2.   Properties

     The  Company's  offices are located at 1401  Walnut  Street,
Suite  540,  Boulder,  Colorado 80302.  The  Company  leases  its
headquarters  offices for $1,883 per month, on a month  to  month
basis,  under  a  sub-lease from Professional  Sales  Associates,
Inc.,  a dental equipment marketing firm for which three  of  the
Company's  directors are also directors and two of such directors
are also shareholders.  The per square foot cost of the Company's
spaces under its sub-lease equals the per-square foot cost of the
master lease, and the Company's sub-lease is subject to the terms
of the master lease.  The master lease under which the Company is
sub-lessee  expires January 31, 2000.  The Company's  sub-tenancy
has  been  ratified by a disinterested majority of the  Board  of
Directors,  which  does  not feel that the  Company's  operations
would  be  unduly  inconvenienced were the  Company  required  to
relocate its three headquarters employees.  Although the Board of
Directors believes that the monthly rental for its Boulder office
facility is comparable to rents charged for comparable properties
in  the market area, the terms of such lease may not be the  same
as  might  have been negotiated with a third party  in  an  arms'
length transaction.  See  "Item  12 - Certain  Relationships  and
Related Party Transactions."

     Biotrol's  office,  assemblage  and  warehouse  facility  is
located  at  650  South  Taylor  Avenue,  Suite  20,  Louisville,
Colorado  80027.   Biotrol  leases 15,005  square  feet  from  an
organization,  which is not affiliated with  Biotrol.   Biotrol's
lease  expires  March 31, 1999.  Biotrol currently  pays  monthly
rental  of $7,965, which will escalate to $8,365 per month during
the  final  year of the lease term.  Biotrol is also  responsible
for its proportionate share of common expenses.

     Challenge owns an office and manufacturing facility  located
at 1100 Bluff Drive, Osage Beach, Missouri 65065.  The office and
manufacturing facility is approximately 14,000 square feet on 1.2
acres  of  land.   In  addition,  Challenge  has  8.8  acres   of
undeveloped land adjacent to the manufacturing facility.

     Micro's office and manufacturing facility is located at  151
East Columbine Avenue, Santa Ana, California 92707.  Micro leases
the facility under a previously existing lease from Mr. Ronald G.
Coss, currently a director of the Company, at a monthly rental of
$28,237.   The  Company's management believes  that  the  monthly
rental  is  comparable to rents charged for comparable properties
in  the  market area, but the terms of the lease may not  be  the
same as might have been negotiated with a third party in an arms'
length  transaction.  The property upon which the Micro plant  is
located  contains  ground water monitoring devices  in  order  to
comply with applicable California and EPA regulations relating to
activities  of  a  prior owner of the property.  Such  monitoring
activity  has  not to date indicated a requirement  for  remedial
action.   Micro  and the Company require full compliance  by  the
lessor  with applicable California and EPA standards.  See  "Item
12 - Certain Relationships and Related Party Transactions."

     OMS'  offices  and manufacturing facilities are  located  at
1800 N.W. 169th Place, Suite C100, Beaverton, Oregon 07005.   OMS
leases  the facility from an unrelated third party, at a  monthly
lease  rate  of $7,289, with the lease to terminate  on  May  31,
1999.
     
     
     The  Company  continues to lease space in Sears'  stores  in
connection  with  its former dental clinic management  operation.
All but one of  those leases expired in 1997, as indicated below. 
The company  currently  subleases  the remaining space to the new
owner of the dental clinic  management operations under identical
terms. It in turn  subleases  the space  to the  new owner of the
dental clinic management operation under identical terms.

     Details  of  the  leases for dental care offices  in  Sears'
premises are as follows:

 Date

        requires  monthly  payments of $3,675 per  month.   Lease
        term commenced December 1, 1984 and ended April 30, 1997.

1979         Sunrise Mall, 5900 Sunrise Mall, Citrus Heights, CA.
        4,900  square  feet.   Lease currently  requires  monthly
        payments of $6,817 per month.  Lease term commenced March
        2, 1988 and ended June 30, 1997.

1987         Santa Rosa Mall,  100  Santa Rosa Plaza, Santa Rosa,
        CA.  1,634 square feet.  Lease  requires monthly payments
        of $3,434 per month.   Lease  term commenced November 24,
        1986 and ended February 8, 1997.

     Professional  Dental Management, L.L.C.,  the  purchaser  of
certain  assets  of  the Company's DCM subsidiary,  is  currently
renegotiating the above-expired leases on its own behalf.

Item 3.   Legal Proceedings

     On  July 9,  1997,  Cottrell   Ltd.,   Englewood,   Colorado
("Cottrell") filed a civil action in the U.S. District Court  for
the  District  of  Colorado against Biotrol  International,  Inc.
("Biotrol"),  a  wholly owned subsidiary of the Company  and  the
Company.   The  complaint demands that Biotrol (and the  Company)
stop   advertising   and  selling  hard  surface   cleaners   and
disinfectants  under labels Cottrell alleges contain  exaggerated
claims.   The  complaint seeks compensation for lost profits  and
other compensation in an amount to be determined at trial.

     Both  Biotrol and Cottrell sell cleaning solutions to dental
dealers.   The  products  are used to disinfect  countertops  and
other  hard  surfaces in dental offices.  The U.S.  Environmental
Protection  Agency  ("EPA") regulates such products  and  reviews
advertising  and  labeling  claims made  about  the  products  by
manufacturers.   The  thrust  of the action  involves  a  Biotrol
product  identified as "Birexse".  Cottrell's  complaint  alleges
that, according to EPA standards, Birexse should be used the same
day it is mixed.  Cottrell makes a competing product that must be
used the same day it is mixed, according to its label.  It is the
Company's  position  that "Birexse" labeling is  consistent  with
that approved by the EPA.

     The  Company's  management  is currently  investigating  the
claims  and  intends  to vigorously defend  against  the  action.
Based  on  the  Company's current understanding of  the  relevant
facts  and  law, management does not expect that the  outcome  of
these  legal proceedings will have a material adverse  effect  on
the  consolidated  financial  condition,  operating  results,  or
liquidity  of  the Company.  See "Pro-Dex Consolidated  Financial
Statements - Note 4."

Item 4.   Submission of Matters to a Vote of Security Holders

     During  the  year ended June 30, 1997, three proposals  were
submitted to the vote of security holders at the Company's annual
meeting, held in Newport Beach, California, on November 13, 1996.
The Company's Inspector of Elections reported that the holders of
5,162,143  shares, comprising 57% of the Company's  common  stock
voted  in  person  at  the meeting.  The following  matters  were
approved,  each of which was described in further  detail  in  an
information  statement  filed with the  Securities  and  Exchange
Commission   and  transmitted  prior  to  the  meeting   to   the
shareholders of record as of the record date:
     
     Proposal 1.    To elect Richard N. Reinhardt (with 5,162,143
votes),  Robert  A.  Hovee (with 5,162,143 votes),  and  John  B.
Zaepfel (with 5,162,143 votes) as members of the Company's  Board
of  Directors.   See  "Item  9  -  Management"  for  biographical
information.
     
     Proposal  2.   To authorize the amendment of the  Directors'
Stock Option Plan, to grant options to non-employee directors  on
commencement  of service as a director, as well as  to  expressly
authorize  such  further grants of options not  more  often  than
annually as the Board of Directors shall determine by vote of the
disinterested  directors, with 5,162,143  votes  in  favor.   See
"Item 10 - Director Compensation."
     
     Proposal  3.   To  ratify selection of McGladrey  &  Pullen,
L.L.P. as the independent certifying accountants of the Company's
financial  statements for the year ending  June  30,  1998,  with
5,162,143  in favor, 0 opposed, and abstaining.  See  "Item  8  -
Changes in Accountants."

                                
                             PART II


Item 5.   Market  for  Registrant's common stock  and  Related
          Stockholder Matters

     The  Company's  common stock is quoted on the  NASDAQ,  Inc.
SmallCap MarketTM under the symbol "PDEX". The range of high  and
low  bid quotations for each quarterly period during the last two
fiscal years of the Company as furnished by NASDAQ is as follows:

     Fiscal Year - 1996          High Bid       Low Bid
     ------------------          --------       -------           
        First quarter              $3.06         $2.25
        Second quarter              3.63          2.13
        Third quarter               4.56          3.06
        Fourth quarter              6.00          3.75
         
     Fiscal Year - 1997          High Bid        Low Bid
     ------------------          --------        ------- 
        First quarter              $4.88         $3.31
        Second quarter              4.25          2.31
        Third quarter               2.81          1.25
        Fourth quarter              2.50          1.38

     On  September  17, 1997, the last sale price of  the  common
stock  as reported by NASDAQ was $2.44 per share.  The last  sale
price reported on NASDAQ on June 30, 1997 was $2.38 per share.

     The  above  quotations reflect inter-dealer prices,  without
retail  mark-up, markdown, or commissions and may not necessarily
represent actual transactions.

     At  June  30,  1997, the approximate number  of  holders  of
record  of the Company's common stock was 414.  This number  does
not  include  beneficial  owners  who  hold  their  shares  in  a
depository trust in "street" name.

     The  Company has not paid any cash dividends on  its  common
stock and has no current plan to pay cash dividends on its common
stock.  Payment of dividends in the future is dependent upon  the
financial  condition, capital requirements, and earnings  of  the
Company  and  such other factors, as the Board of  Directors  may
deem relevant.  It is not anticipated that dividends will be paid
in  the  near future, and in accordance with the company's credit
agreement  with the bank,  it is prevented from paying  dividends
without prior consent.

                         $19,196,835   $20,571,075   $(1,374,240)
                         ============  ============  ============

     The increase in sales at Biotrol for the year ended June 30,
1997 is primarily attributable to an increase in sales of certain
infection control products, and the complete line of preventative
care  dental  products.  At Challenge, an increase  in  sales  of
preventative care products to Biotrol mainly contributed  to  the
overall  increase  in  sales for  the year ended June  30,  1997.
Sales  to private label customers of Challenge decreased  by  11%
from  $743,461 for the year ended June 30, 1996 to  $661,163  for
the  year  ended   June  30, 1997.   Micro  Motors    experienced  
the  loss  of  a large  private  label  customer  for  its dental
hand-pieces.   Sales  of  its branded  hand-piece  line  did  not
increase  sufficiently to offset the loss of  the  private  label
business.   Efforts are being made to develop new  private  label
customers  to replace the lost business.  In April,  the  Company
announced  that Micro Motors had entered into an exclusive  long-
term  agreement  with  Tycom,  Inc. to  supply  Electric  Control
Systems  and Handpieces for Tycom's "Quantec" endodontic  product
line.   Also,  effective July 1, 1997, the  marketing  and  sales
responsibility for the branded hand-piece line has  been  shifted
from an independent sales organization to the sales force already
in  place at Biotrol.  In anticipation of that event as  well  as
the  introduction  of several new products scheduled  for  fiscal
year  ended June 30, 1998, Biotrol increased its sales force from
11  to 16 people.  During the first half of the year sales at the
Company's  OMS  subsidiary were below  the  same  period  in  the
previous   fiscal  year  due  to  the  downturn  in  demand   for
semiconductor  fabrication equipment.   Sales  to  that  industry
decreased by approximately 14% for the first six months  of  year
ended June 30, 1997.
     
     Beginning  in  the latter part of the third quarter  of  the
current fiscal year, and continuing into the fourth quarter sales
have  increased  at  OMS  as  a result  of  the  rebound  in  the
semiconductor  industry.  Also, sales of  infection  control  and
preventative dental products at the Company's Biotrol  subsidiary
increased  7%  over  the previous quarter ended  June  30,  1996.
Overall Company sales for the fourth quarter ended June 30,  1997
increased 2% to $5,600,000 from $5,500,000 in the fourth  quarter
ended June 30, 1996.
     
     Overall net consolidated sales of the Company decreased 6.7%
from   $20,571,000  in  fiscal  year  ended  June  30,  1996   to
$19,197,000 in fiscal year ended June 30, 1997.

                         $11,035,173   $12,062,230   $(1,027,057)
                         ===========   ===========   ============

     Gross  profit  decreased 8.7% to $11,035,000  for  the  year
ended June 30, 1997 from $12,087,000 for the year ended June  30,
1996  primarily due to a decrease in sales.  Gross profit dollars
increased at Biotrol and Challenge due to the increase  in  sales
at  those subsidiaries.  Gross profit dollars decreased at  Micro
Motors and OMS primarily due to the decrease in revenue.
     
     Gross  profit as a percentage of sales decreased from  58.7%
in  fiscal year ended June 30, 1996 to 57.5% in fiscal year ended
June  30,  1996.   The decrease is attributed to an  increase  in
manufacturing costs that could not entirely be passed through  to
customers.
     
     Operating expenses increased 15.6% to $10,945,000 in  fiscal
year  ended  June 30, 1997 from $9,469,000 in fiscal  year  ended
June  30, 1996.  During the year ended June 30, 1997 the  Company
incurred  $463,000  of  unusual  one-time  restructuring  charges
including  severance benefits paid to terminated employees.   The
Company also increased its commitment to research and development
by  spending an additional $179,000 during fiscal year ended June
30,  1997.  Also, operating expenses for year ended June 30, 1996
include only eleven months of operations for Micro Motors and OMS
since the acquisition of those subsidiaries occurred on July  26,
1995.   Due  to the restructuring management estimates  that  the
reduction  of its employee workforce along with other operational
changes  will  provide an anticipated $900,000 of  future  annual
cost savings.
     
     The  Company's  effective tax rate  on  income  (loss)  from
continuing operations was 22.1% in 1997 and 22.2% in  1996.   For
1997  the  tax  benefit rate was reduced mainly because  of  non-
deductible  expense items of $149,000, primarily  goodwill.   For
1996  the  tax  rate  was reduced because  of  a  change  in  the
valuation   allowance  for  deferred  tax  assets  of   $432,000.
Realization  of  deferred tax assets is dependent  on  generating
sufficient  taxable income prior to the expiration  of  the  loss
carryforwards.   Although realization is not assured,  management
believes  it  is more likely than not that the net  deferred  tax
assets will be realized for the following reasons.  During  1997,
the  Company  incurred  losses from  discontinued  operations  of
$696,000  (net  of  tax  benefit).  These  operations  have  been
eliminated.  In  addition,  the  Company  incurred  approximately
$827,000  in  one-time  charges  to   operations  for   severance
benefits  paid  to  terminated  employees,  prepayment   fees  to
its  previous  lender  and  other  unusual charges.  As  part  of
this  restructuring, management estimates that the  reduction  of
its  employee  workforce  resulting in  an  anticipated  $900,000
annual cost saving will also improve profitability in the future.
Management  has  provided a valuation allowance  related  to  net
operating  loss  carryforwards, which  are  not  expected  to  be
realized  in  a one-year period.  The amount of the net  deferred
tax asset considered realizable, however, could be reduced in the
near  term  if  estimates  of future taxable  income  during  the
carryforward period are reduced.
     
     For 1997, income (loss) from continuing operations decreased
$2,146,000 from income of $1,260,000 for year ended June 30, 1996
to  a loss of $887,000 for year ended June 30, 1997.  In addition
to  the unusual charges of $463,000 incurred in the current  year
mentioned above, the Company charged to current year's earnings a
one-time  prepayment  penalty  fee  to  its  previous  lender  of
$365,000.
     
     On April 25, 1997 pursuant to the acquisition agreement, the
Company  completed the unwind of the Pnu-Light transaction.   The
Company  received  all 368,483 shares of its  stock,  which  were
issued  as consideration for the purchase of the assets  of  Pnu-
Light.    Losses   sustained  by  Pnu-Light   are   reported   as
discontinued  operations and amounted to  approximately  $295,000
and  $54,000 net of related tax benefits of $149,000 and  $20,000
for 1997 and 1996 respectively.
     
     On  June 12, 1997, the Company completed the sale of certain
assets  of  its  dental  clinic  management  (DCM)  operation  In
California.    Losses   sustained  by  DCM   are   presented   as
discontinued  operations and amounted to  approximately  $401,000
and  $32,000  net of related income tax benefits of approximately
$265,000  and  $14,000  in 1997 and 1996.  The  Company  retained
ownership  of  the  accounts  receivable  of  the  dental  clinic
management  operation.   The  Company  expects  to  receive  with
assistance from the purchaser, net proceeds of approximately $1.8
million from the collection of those receivables over the next 12
to  24  months.   If the allowance for doubtful accounts  is  not
adequate  to  realize  the  net amount of  the  DCM  receivables,
additional  losses from discontinued operations  could  occur  in
future years.

Liquidity and Capital Resources
- -------------------------------
     
     The  operations  of  the  Company are conducted  principally
through  its wholly owned subsidiaries.  The Company's  financial
position at June 30, 1997 remains strong with working capital  on
that  date  of $6,938,000 compared with $5,309,000  at  June  30,
1996.   Cash  and cash equivalents totaled $851,000 at  June  30,
1997  compared to $407,722 at June 30, 1996.  Net  cash  used  in
operations  was $986,000 for the year ended June 30,  1997.   The
Company provided $1,042,000 in cash from operations for the  year
ended June 30, 1996.  Included in operating expenses are non-cash
items  for amortization of goodwill and patents totaling $901,000
in  1997  and  $712,000  in 1996.  Although  these  expenses  are
included  in  the calculation of net income (loss), they  do  not
represent a current use of cash.
     
     The  Company's  principal source of  liquidity  during  year
ended  June 30, 1997 was cash on hand and a net increase in  long
term  borrowings of approximately $4,000,000.  During year  ended
June  30,  1996  the Company's principal source of liquidity  was
provided  from cash on hand and a net increase in both short  and
long term borrowings of $3,611,000.
     
     On  July 26, 1996 the Company obtained a $10,000,000  credit
facility  from Harris Bank secured by all assets of  the  Company
and  guaranteed  by  each  of  the Company's  subsidiaries.   The
facility  consists  of a $6,000,000 term loan  with  a  five-year
amortization  period, and a $4,000,000 revolving line  of  credit
with  a  termination  date  on July 24,  1999.   Both  facilities
require  monthly  interest payments at the prime  rate  or  at  a
variable  interest rate from 1.5% to 2% above  LIBOR.   The  term
loan  portion  is  payable  in equal  quarterly  installments  of
$200,000 through July 24, 2001, when the full amount of the  then
unpaid  balance of the note will be due.  The term  loan  had  an
outstanding balance on June 30, 1997 of $5,200,000.  The revolver
portion of the facility had an outstanding balance at June 30,997
of  $3,100,000.   At  June 30, 1997 $900,000  remained  available
under  the revolver/term agreement.  As a condition of the credit
facilities,  the  Company is required to meet  certain  financial
covenants  including minimum tangible net worth,  debt  to  total
capitalization,  interest coverage, fixed  charge  coverage,  and
cash flow.  In addition, the credit facility limits the amount of
dividends and capital expenditures in any one year.  At June  30,
1997  the  Company did not meet most of the financial  covenants;
however,  on  September  26, 1997 the  bank  waived  the  current
covenants and amended the agreement such that management believes
the Company will be in compliance in the future.
     
     Management  believes  that  the  Company's  existing  credit
resources, including the credit facility with Harris Bank as well
as  internally generated funds, should be sufficient  to  satisfy
the  Company's  requirements for cash flows  for  operations  and
capital  expenditures for fiscal 1998.  Capital expenditures  for
the  Company's operations for the year ended June  30,  1998  are
presently anticipated to be approximately $850,000.

Years Ended June 30, 1996 and 1997
- ----------------------------------

     Net  cash  used by operating activities in 1997 was $986,000
compared  to  net  cash  provided from  operating  activities  of
$1,042,000  in  1996.  Increases in refundable  income  taxes  of
$580,000,  and decreases in accounts payable of $511,000  reduced
net  cash in 1997.  Net cash was reduced by increases in accounts
receivable of $1,535,000 in 1996.

     Net  cash  used  in  investing activities was  $490,000  and
$4,674,000 in 1997 and 1996 respectively.  In 1996 cash  used  in
investing activities related primarily to the acquisition of  new
subsidiaries.   Net cash used in 1997 related  primarily  to  the
acquisition of equipment.

     Net cash provided by financing activities was $1,920,000 and
$3,655,000  in 1997 and 1996.  Net cash from financing activities
was primarily provided by long term borrowings in both years.
     
Accounting Changes
- ------------------
     
     Effective  for  annual  and  interim  periods  ending  after
December  15,  1997,  the  Financial Accounting  Standards  Board
(FASB) has issued Statement No. 128, "Earnings Per Share",  which
supercedes  APB Opinion No. 15.  Statement No. 128  requires  the
presentation  of  earnings per share by all  entities  that  have
common stock or potential common stock, such as options, warrants
and  convertible securities outstanding that trade  in  a  public
market.   Those entities that have only common stock  outstanding
are  required  to  present  basic  earnings  per  share  amounts.
Diluted  per  share  amounts assume the conversion,  exercise  or
issuance  of  all potential common stock instruments  unless  the
effect  is  to  reduce a loss or increase the income  per  common
share from continuing operations.  The adoption of Statement  No.
128 would have no effect on 1997 reported (loss) per share.
     
     The FASB has also issued Statement No. 131 "Disclosure about
Segments  of  an Enterprise and Related Information".   Statement
No.  131  modifies  the  disclosure requirements  for  reportable
segments and is effective for the Company's year ending June  30,
1999.  The Company has not determined the effect the adoption  of
this Statement would have on the Company's reported segments.

Impact of Inflation and Changing Prices
- ---------------------------------------

     The  industries  in  which the Company  competes  are  labor
intensive, often involving personnel with high level technical or
sales  skills.  Wages and other expenses increase during  periods
of  inflation and when shortages in the marketplace  occur.   The
Company  expects its subsidiaries to face somewhat  higher  labor
costs, as the market for personnel with the skills sought by  the
Company  becomes  tighter in a period  of  full  employment.   In
addition,  suppliers  pass along rising costs  to  the  Company's
subsidiaries  in  the  form  of  higher  prices.   Further,   the
Company's  credit  facility with Harris Bank  involves  increased
costs  if domestic interest rates rise or there are other adverse
changes  in  the  international interest rates,  exchange  rates,
and/or  Eurocredit availability.  To some extent,  the  Company's
subsidiaries  have  been  able to offset increases  in  operating
costs  by increasing charges, expanding services and implementing
cost  control  measures.  Nevertheless,  each  of  the  Company's
subsidiaries'  ability to increase prices is  limited  by  market
conditions,  including international competition in many  of  the
Company's markets.

Other Matters
- -------------

     Presently  the Company's information technology systems  are
inadequate  to  handle  year  2000 requirements.   Management  is
reviewing  recommendations  to upgrade  the  Company's  and  each
subsidiary's entire information technology system.  Many  of  the
software  applications at each subsidiary will  be  improved  and
made  to  comply with the year 2000 requirements.  The  operating
plan  for  fiscal year ended June 30, 1998 includes the estimated
cost  to accomplish the improvements to the Company's information
technology capabilities.

               INDEPENDENT AUDITOR'S REPORT


To the Board of Directors
Pro-Dex, Inc.
Boulder, Colorado


We  have  audited the accompanying consolidated balance sheet  of
Pro-Dex,  Inc. and Subsidiaries (the "Company") as  of  June  30,
1997,  and  the  related consolidated statements  of  operations,
shareholders' equity, and cash flows for the years ended June 30,
1997 and 1996.  These financial statements are the responsibility
of  the  Company's Management.  Our responsibility is to  express
opinion on these financial statements based on our audits.

We  conducted  our  audit in accordance with  generally  accepted
auditing  standards.  Those standards require that  we  plan  and
perform  the  audit to obtain reasonable assurance about  whether
the  financial statements are free of material misstatement.   An
audit includes examining on a test basis, evidence supporting the
amounts  and disclosures in the financial statements.   An  audit
also  includes  assessing  the  accounting  principles  used  and
significant  estimates made by management, as well as  evaluating
the  overall  financial statement presentation.  We believe  that
our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above  present  fairly, in all material respects,  the  financial

                PRO-DEX, INC. AND SUBSIDIARIES
      
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    JUNE 30, 1997 AND 1996


NOTE 1 - SUMMARY OF ACCOUNTING POLICIES

Nature of Business
- ------------------

Pro-Dex,  Inc.  (the  Company) is the parent  of  four  operating
subsidiaries,  Biotrol International, Inc.  (Biotrol),  Challenge
Products,  Inc.  (Challenge), Micro  Motors,  Inc.  (Micro),  and
Oregon Micro Systems, Inc. (OMS).  Biotrol is a manufacturer  and
supplier  of infection control products for the dental  industry.
Challenge manufactures and sells fluoride products for preventive
dentistry, along with a complementary line of products  used  for
the   cleaning,  whitening,  and  protection  of  teeth.    Micro
manufactures miniature pneumatic motors used in dental,  medical,
and  industrial devices worldwide as well as a complete  line  of
dental handpieces.  OMS designs, develops and manufactures multi-
axis  circuit  boards  used to control the motion  of  servo  and
stepper   motors  predominantly  used  in  the  medical   testing
equipment  industry and the computer chip manufacturing industry.
The  Company extends credit to its customers, all on an unsecured
basis,  on  terms  that it establishes for individual  customers.
Customers  are located predominately in the United States.   Many
of  the Company's products are regulated by a number of state and
federal regulatory bodies, including the Environmental Protection
Agency  ("EPA")  and  the  Food and Drug Administration  ("FDA").
While  the  Company's management and management of  each  of  the
Company's  operating subsidiaries make every effort  to  maintain
full  compliance with all applicable laws and regulations,  there
exists an ongoing risk that one or more of its activities may  at
some  point  be  determined to be non-compliant.  Notwithstanding
the  risks inherent in the Company's business sectors, management
believes  that each of the Company's subsidiaries enjoys  a  good
reputation for compliance with applicable regulations.

Principles of Consolidation
- ---------------------------

The consolidated financial statements include the accounts of the
Company  and  all  of  its subsidiaries.  All significant  inter-
company accounts and transactions have been eliminated.

Revenue Recognition
- -------------------

Revenue  on  product  sales is recognized upon  shipment  to  the
customer.  The Company sells some of its products with a warranty
that  provides for repairs or replacement of any defective  parts
for  a  period  after the sale.  At the time  of  the  sale,  the
Company accrues an estimate of the cost of providing the warranty
based on prior experience.

Cash and Cash Equivalents
- -------------------------

The  Company considers highly liquid investments with a  maturity
of three months or less when purchased to be cash equivalents.

Inventories
- -----------

Inventories are stated at the lower of cost or market.   Cost  is
determined  using  the first-in, first-out  method.   Inventories
consist of the following:

  Raw materials                                       $   709,528
  Work in process                                         352,367
  Finished goods                                        3,265,174
                                                      -----------
    Total                                               4,327,069
  Reserve for slow moving inventories                      91,000
                                                      -----------
    Total inventories, net                            $ 4,236,069
                                                      ===========

Property and Equipment
- ----------------------

Property  and  equipment  are stated at  cost.   Depreciation  is
provided using the straight-line method over the estimated useful
lives  of the assets as follows: Buildings-- generally 40  years,
equipment--  3  -  10  years;  leasehold  improvements  7  years.
Leasehold  improvements are depreciated over the shorter  of  the
term of the lease or their estimated useful lives.

Intangible Assets
- -----------------

Intangible  assets  include  patents,  organization  costs,  non-
compete  contracts and the cost of net assets acquired in  excess
of  fair value which are amortized on a straight-line basis  over
their  estimated  useful  lives  ranging  from  5  to  20  years.
Intangible  assets are stated net of accumulated amortization  of
$1,613,000.

The  Company  evaluates impairment of its long-lived  assets  and
certain   intangible  assets  whenever  events  or   changes   in
circumstances indicate that the carrying amount of the asset  may
not  be  recoverable  in  accordance  with  Financial  Accounting
Standards  Board  (FASB) Statement No. 121.  An asset  is  deemed
impaired  if  the sum of the expected future cash flows  is  less
than the carrying amount of the asset.

Advertising
- -----------

The  Company expenses the cost of advertising the first time  the
advertising  takes  place.   No  amounts  are  included  in   the
Company's  balance  sheet for deferred  advertising  costs.   The
Company  incurred advertising expenses of approximately  $500,000
and $581,000 in 1997 and 1996, respectively.

Reclassifications
- -----------------

Certain items in the June 30, 1996 financial statements have been
reclassified  to  be  comparable  with  the  financial  statement
classifications  for  the  year  ending  June  30,  1997.   These
reclassifications have no effect on shareholders' equity  or  net
income as of and for the year ending June 30, 1996.

Income Taxes
- ------------

Deferred income taxes are provided on a liability method  whereby
deferred  tax  assets  are  recognized for  deductible  temporary
differences  and operating loss and tax credit carryforwards  and
deferred  tax  liabilities are recognized for  taxable  temporary
differences.   Temporary differences are the differences  between
the  reported  amounts of assets and liabilities  and  their  tax
bases.   Deferred tax assets are reduced by a valuation allowance
when,  in  the opinion of management, it is more likely than  not
that  some portion or all of the deferred tax assets will not  be
realized.   Deferred tax assets and liabilities are adjusted  for
the  effects  of  changes in tax laws and rates on  the  date  of
enactment.

Use of Estimates
- ----------------

The  preparation  of  financial  statements  in  conformity  with
generally  accepted accounting principles requires management  to
make  estimates and assumptions that affect the reported  amounts
of assets and liabilities and disclosure of contingent assets and
liabilities  at  the  date of the financial  statements  and  the
reported  amounts of revenues and expenses during  the  reporting
period.  Actual results could differ from those estimates.

Earnings Per Share
- ------------------

Earnings  per share are based on the weighted average  number  of
common shares and common share equivalents outstanding during the
period.  Common share equivalents are excluded if their effect is
anti-dilutive.   Contingent shares are  excluded  if  the  event,
which will cause the shares to be issued, is not likely to occur.
Fully  dilutive  earnings per share have not been  presented,  as
there is no effect on earnings per share.


New Accounting Pronouncements
- -----------------------------

The   Financial  Accounting  Standard  Board  (FASB)  has  issued
Statement  No.  128, "Earnings Per Share", which  supersedes  APB
Opinion  No. 15.  Statement No. 128 requires the presentation  of
earnings  per  share by all entities that have  common  stock  or
potential common stock, such as options, warrants and convertible
securities  outstanding  that trade in a  public  market.   Those
entities that have only common stock outstanding are required  to
present  basic  earnings per share amounts.   Diluted  per  share
amounts  assume  the  conversion, exercise  or  issuance  of  all
potential common stock instruments unless the effect is to reduce
a  loss  or  increase the income per common share from continuing
operations.   All entities required to present per share  amounts
must  initially  apply Statement No. 128 for annual  and  interim
periods  ending after December 15, 1997.  Earlier application  is
not  permitted.  The adoption of Statement No. 128 would have  no
effect on 1997 reported (loss) per share.

The  FASB  has  also  issued Statement No. 131 "Disclosure  about
Segments  of  an Enterprise and Related Information".   Statement
No.  131  modifies  the  disclosure requirements  for  reportable
segments and is effective for the Company's year ending June  30,
1999.   The Company has not determined the effect of the adoption
of this Statement would have on the Company's reported segments.

Fair Value of Financial Instruments
- -----------------------------------

The  method  and assumptions used to estimate the fair  value  of
long-term debt, which approximates the carrying value,  is  based
on interest rates that are currently available to the Company for
issuance  of  debt  with similar terms and remaining  maturities.
The  fair value of trade accounts receivable and accounts payable
approximate carrying value.

NOTE 2 - ACCOUNTS RECEIVABLE

Accounts  receivable  includes amounts due  for  dental  services
rendered  to  patients under an extended term payment arrangement
totaling $2,429,627.  General dentistry billings may be paid over
ten  monthly  installments and billings for orthodontic  services
are paid over a twenty-four month installment arrangement.  These
receivables  were  generated  by  the  Company's  Dental   Clinic
Management (DCM) operation.  In June 1997, the Company sold  this
operation  to PDM and no longer provides this service  (Note  9).
It is estimated that the Company will collect $900,000 of the DCM
accounts  receivable within the next 12 months.  The  balance  is
included   in  long-term  trade  accounts  receivable.   Accounts
receivable   are  stated  net  of  an  allowance   of   $707,702.
Management   has  estimated  their  reserve  based   on   current
information  available.   However,  future  changes  in   payment
trends,  the economy or other factors could effect the amount  of
the required reserve.

NOTE 3 - LONG-TERM DEBT

Following is a summary of long-term debt:

  Revolving/term loan from bank (a)                   $ 8,300,000

    including interest to May 30, 1999                    149,495
                                                        
  Mortgage payable secured by land and building,          
    bearing interest at 2% over prime, maturing                      
    $1,967 monthly due November 12, 1997. This note          
    is normally renewed for successive one-year terms.    181,289
                                                        
  Other secured notes at various interest                     
    rates and various maturities.                         154,267
                                                      -----------
  Total                                                 9,656,544
  Less current portion                                  1,211,999
                                                      -----------
  Total long-term debt                                $ 8,444,545
                                                      ===========

(a)  The Company has obtained a $10,000,000 credit facility  from
     Harris  Bank  secured  by  all  assets  of  the  Company and
     guaranteed by  each  of  the  Company's  subsidiaries.   The
     Facility consists of a $6,000,000 term loan with a five-year
     amortization  period,  and  a  $4,000,000  revolving line of
     credit  with  a  termination  date  on  July 24, 1999.  Both
     facilities  require  monthly  interest payments at the prime
     rate or  at  a  variable interest rate from 1.5% to 2% above
     LIBOR.  The  term loan portion is payable in equal quarterly
     installments  of  $200,000  through  July 24, 2001, when the
     full amount  of the  then unpaid balance of the note will be
     due. The  term  loan  had an outstanding balance on June 30,
     1997  of $5,200,000.   The  revolver portion of the facility
     had  an  outstanding balance at June 30, 1997 of $3,100,000.
     At  June 30, 1997,  $900,000  remained  available  under the
     revolver/term loan.  The Company is required to meet certain
     financial covenants including minimum  tangible  net  worth,
     debt  to  total  capitalization,  interest  coverage,  fixed
     charge  coverage, and  cash  flow.  In  addition, the credit
     facility   limits   the  amount  of  dividends  and  capital
     expenditures in any one year.  At June 30, 1997, the Company
     did  not  meet  most of the  financial  covenants;  however,
     on September 26, 1997, the bank waived the current covenants
     and amended the agreement such that management believes  the
     Company will be in compliance in the future.

(b)  These amounts are due to the former  owner of  Micro  Motors
     and the Company's largest shareholder  and  are subordinated
     to the bank debt discussed above.

     Aggregate maturities on long-term debt  for  the  next  five
     years is as follows:  1998,  $1,211,999;  1999,  $3,612,706;
     2000, $1,148,781;  and 2001, $3,683,058.

NOTE 4 - COMMITMENTS AND CONTINGENCIES

Micro  Motors  leases  office and warehouse facilities  from  the
Company's  largest shareholder.  The Company and its subsidiaries
also  lease other office and warehouse facilities from  unrelated
parties  under  lease  agreements  expiring  from  February  1999
through  March 2001.  These leases generally require the  Company
to pay insurance, taxes, and other expenses related to the leased
space.   Total  rent expense was $902,187 and $810,763  including
approximately $335,000 paid to the Company's largest  shareholder
for the years ended June 30, 1997 and 1996.  Future minimum lease
payments  for the years ending June 30, amount to 1998, $879,006;
1999,   $872,971;  2000,  $355,867;  2001,  $261,281;  total   of
$2,369,125,   including  $1,306,066  to  the  Company's   largest
shareholder.   The Company subleases the dental centers  occupied
by  DCM  under lease agreements expiring at various  dates  until
March  1999 (Note 9).  Future minimum sublease receipts  for  the
years  ending  June 30 amount to 1998, $327,504,  and  for  1999,
$327,504.

On July 9, 1997, Cottrell Ltd., Englewood, Colorado  ("Cottrell")
filed  a  civil  action  in  the  U.S.  District  Court  for  the
District   of   Colorado  against   Biotrol  International,  Inc.
("Biotrol"),  a  wholly owned subsidiary of the Company  and  the
Company.   The  complaint demands that Biotrol (and the  Company)
stop   advertising   and  selling  hard  surface   cleaners   and
disinfectants  under labels Cottrell alleges contain  exaggerated
claims.   The  complaint seeks compensation for lost profits  and
other compensation in an amount to be determined at trial.

Both  Biotrol and  Cottrell  sell  cleaning  solutions  to dental
dealers.   The  products  are used to disinfect  countertops  and
other  hard  surfaces in dental offices.  The U.S.  Environmental
Protection  Agency  ("EPA") regulates such products  and  reviews
advertising  and  labeling  claims made  about  the  products  by
manufacturers.   The  thrust  of the action  involves  a  Biotrol
product  identified as "BirexSE".  Cottrell's  complaint  alleges
that, according to EPA standards, Birexse should be used the same
day it is mixed.  Cottrell makes a competing product that must be
used the same day it is mixed, according to its label.  It is the
Company's  position  that "BirexSE" labeling is  consistent  with
that approved by the EPA.

The  Company's   management  is  currently   investigating    the
claims  and  intends  to vigorously defend  against  the  action.
Based  on  the  Company's current understanding of  the  relevant
facts  and  law, management does not expect that the  outcome  of
these  legal proceedings will have a material adverse  effect  on
the  consolidated  financial  condition,  operating  results,  or
liquidity  of  the Company.

NOTE 5 - INCOME TAXES

The provision for income taxes (credits) for the years ended June
30, 1997 and 1996 is as follows:

Net   deferred  tax  assets  of  $475,000  are  included  in  the
accompanying  balance  sheet  as current  assets.  The  remaining
deferred  tax assets of $505,000 are included in the accompanying
balance sheet as long term assets.

A  portion of these deferred tax assets reflects the benefit of a
$875,000  tax loss carryforward, which expires $620,000  in  2003
and $255,000 in 2004.  Utilization of these loss carryforwards is
limited  under income tax rules to $480,000 in 1998 and  $280,000
per  year  thereafter.   Realization of deferred  tax  assets  is
dependent  on generating sufficient taxable income (approximately
$2.5  million) prior to the expiration of the loss carryforwards.
Although  realization is not assured, management believes  it  is
more  likely  than not that the net deferred tax assets  will  be
realized  for  the following reasons.  During 1997,  the  Company
incurred losses from discontinued operations of $696,000 (net  of
tax benefit).  As discussed in Note 9, these operations have been
eliminated.  In addition, the Company also incurred approximately
$827,000 in one-time charges to operations for severance benefits
paid  to  terminated employees, prepayment fees to  its  previous
lender and other unusual charges.  As part of this restructuring,
management estimates that the reduction of its employee workforce
resulting in an anticipated $900,000 annual cost saving will also
improve  profitability in the future.  Management has provided  a
valuation  reserve of $285,000 related to the net operating  loss
carryforwards, which are not expected to be realized within a one
- -year period. The amount of the net deferred tax asset considered
realizable,  however,  could  be reduced  in  the  near  term  if
estimates of future taxable income during the carryforward period
are reduced.

NOTE 6 - STOCK OPTIONS AND WARRANTS

The  Board  of Directors and the shareholders of the Company have
approved  and adopted three plans, pursuant to which  options  to
purchase  2,150,000  shares of common stock  can  be  granted  to
officers, directors, employees and to others expected to  provide
significant services to the Company.  There are  1,159,196 shares
remaining in the option plans, which are available for  grant  in
future  years.  In addition, the Company has issued  warrants  to
acquire 113,000 shares, exercisable at an average price of  $2.17
and expiring on July 26, 2005.

Transactions  involving  the  stock  options  are  summarized  as

The three option plans are substantially similar and call for the
vesting  as  approved  by  the Board of Directors  (usually  upon
grant), and allow for the options to be outstanding for a  period
of ten years.

Grants  under the Company's stock option plans are accounted  for
following   APB  Opinion  No.  25  and  related  interpretations.
Accordingly, no compensation cost has been recognized for  grants
under  the  plan.   Had  compensation  cost  for  the  stock-base
compensation plans been determined based on the grant  date  fair
values  of  awards  (the method described in FASB  Statement  No.
123),  reported net income (loss) and earnings (loss) per  common
share  would  have  been  adjusted to the proforma  amount  shown
below:

The fair value of each grant is estimated at the grant date using
the   Black-Scholes  option-pricing  model  with  the   following
weighted-average  assumptions  for  grants  in  1996  and   1997,
respectively: no dividend rate for all years; price volatility of
31%  in  1996  and  43%  in  1997; risk-free  interest  rates  of
approximately  5.9% in 1996 and 6.8% in 1997; and expected  lives
of five years.

NOTE 7 - PREFERRED SHARES

Holders of Series A preferred shares have no voting, dividend, or
redemption  rights.  In the event of liquidation or  dissolution,
preferred  shareholders are entitled to receive $3.60 per  share.
Each preferred share is convertible into one common share at  the
option of the holder.

NOTE 8 - EMPLOYEES' BENEFIT PLANS

The  Company  has adopted an employee benefit plan under  Section
401(k)  of  the Internal Revenue Code.  The plan allows employees
to  make  contributions  up to a specified  percentage  of  their
compensation.  Under the plan, the Company is obligated to  match
up to 25% of the employees' contribution up to a defined maximum.
For   the  years  ended  June  30,  1997  and  1996  the  Company
contributed  $35,156  and $36,232, respectively,  as  a  matching
contribution to the 401(k) plan.

In  1973,  Micro  established an Employee  Stock  Ownership  Plan
(ESOP), who's shares of stock in Micro, upon acquisition of Micro
by  the  Company, were converted to restricted Company shares  of
common  stock.   At June 30, 1997, this restriction  had  lapsed.
For  the years ended June 30, 1997 and 1996, the Company did  not
make  any contributions to the ESOP.  During the years ended June
30,  1997  and  1996,  the Company advanced  funds  to  the  ESOP
totaling  $37,800 and $21,300, respectively, in order for  it  to
purchase stock from Plan participants.

NOTE  9  -  BUSINESS ACQUISITIONS, DIVESTITURES, AND DISCONTINUED
            OPERATIONS

On  July  26,  1995, the Company acquired for  cash  all  of  the
outstanding  shares of Oregon Micro Systems, Inc., a manufacturer
of  multi-axis motion control circuit boards.  In addition to the
OMS stock, the Company acquired two letters patent for the design
of  multi-axis motion control circuit boards with an  approximate
value   of   $2,693,000.    The  total   acquisition   cost   was
approximately  $6,700,000.  The excess of the  total  acquisition
cost  over  the  fair  value  of  the  net  assets  acquired  was
approximately  $283,000  and is being amortized  over  a  15-year
period.  The patents are being amortized over seven (7) years  by
the straight-line method.
                                                                 
Also  on  July  26, 1995, Micro Motors, Inc., a  manufacturer  of
patented  miniature pneumatic (air) motors, and dental handpieces
was  acquired  in exchange for 3,350,000 shares of the  Company's
stock.   The  amount assigned to the shares of the Company  stock
was   $2.75   per  share  making  the  total  acquisition   price
$9,212,500.   The excess of the total acquisition cost  of  Micro
Motors,  Inc. over the fair value of the net assets  acquired  of
approximately $7,300,000 is being amortized over 20 years by  the
straight line method.

On  May  11,  1996,  the  Company  acquired  certain  assets  and
liabilities   of  Pnu-Light  Tool  Works,  Inc.,  (Pnu-Light)   a
developer  of  pneumatic light mechanisms  for  hand  tools,  for
common  stock.   The  purchase agreement  called  for  the  final
purchase  price  to be determined based upon a  multiple  of  the
company's net income generated for the year ended June 30,  1999,
and  based  upon the then current market price of  the  Company's
common  stock  with a minimum value assigned to  the  net  assets
purchased  of  $4,000,000, subject to certain  adjustments.   The
agreement also provided that if the computed value based  on  the
prescribed  formula does not exceed  $4,000,000, the Company  had
the  option  to  rescind  the transaction.   The  Company  issued
368,483 shares of stock  at  acquisition  and  recorded  the  net
assets acquired at the  present value  of  the  estimated minimum
purchase price of  approximately  $3,070,000.  The  excess of the
total acquisition  cost  of  Pnu-Light over  the  fair  value  of
the net  assets  acquired of approximately  $1,100,000  was being
amortized over a 15-year period by the straight-line method.

On  April 25, 1997, consistent with the decision of its Board  of
Directors  as  announced  on  February  12,  1997,  the   Company
completed  the  rescission  of  the  Pnu-Light  transaction.   In
accordance  with the agreement, the Company received all  368,483
shares of the Company's stock, which were issued as consideration
for  the  purchase of the assets.  Losses sustained by  Pnu-Light
are   reported  as  discontinued  operations  and   amounted   to
approximately $295,000 and $54,000, net of related  tax  benefits
of $149,000 and $20,000 for 1997 and 1996 respectively.  Revenues
generated by this subsidiary in 1997 and 1996 were immaterial.

On  June  12, 1997, the Company completed the sale of its  Dental
Clinic Management (DCM) operation in California.  In exchange for
inventory  and  property  and  equipment  the  purchaser  assumed
approximately   $670,000  of  the  Company's   liabilities.    In
addition,  with assistance of the purchaser, the Company  expects
to  receive the net proceeds from the collection of approximately
1.8 million in existing net accounts receivable over the next  24
months.   Revenues  of  DCM  were  approximately  $1,986,000  and
$2,420,000   in   1997   and  1996.   Operating   expenses   were
approximately $2,652,000 and $2,466,000 in 1997 and 1996.   These
amounts  are presented as losses from discontinued operations  in
the  statement  of operations and are reported net of  applicable
income tax benefits of approximately $265,000 and $14,000 in 1997
and  1996.   At  June  30,  1997 no assets  of  the  discontinued
operations   remain  other  that  the  DCM  accounts   receivable
discussed above.

All  acquisitions have been accounted for as a purchase  and  the
results  of  operations  of  Oregon Micro  Systems,  Inc.,  Micro
Motors,  Inc., and Pnu-light Tool Works, Inc., since the date  of
acquisition   are   included   in  the   consolidated   financial
statements.

Item  8.    Changes  in  and Disagreements  with  Accountants  on
            Accounting and Financial Disclosures

     During the year ended June 30, 1996, the Company changed its
certifying   accountant.   Effective  November  3,  1995,   Henry
Vanderzee ceased to serve as the independent accountant to  audit
the  Company's financial statements.  Mr. Vanderzee served as the
Company's independent certifying accountant for the fiscal  years
ended  June  30, 1995 and June 30, 1994, as well as prior  years.
The  former  accountant was removed by action  of  the  Board  of
Directors, effective November 3, 1995.  On such date,  the  Board
of   Directors  appointed  McGladrey  &  Pullen,  L.L.P.  as  the
Company's  independent certifying accountant  for  its  financial
statements for the year ended June 30, 1996.  McGladrey & Pullen,
L.L.P.  had  audited  the financial statements  of  Oregon  Micro
Systems,  Inc. and Micro Motors, Inc., two subsidiaries  acquired
by  the  Company on July 26, 1995, for the fiscal years  of  such
companies  ended  March  31,  1995.   Shareholders  ratified  the
appointment  of McGladrey & Pullen, L.L.P. at the Annual  Meeting
of Shareholders on February 27, 1996.

     McGladrey   &   Pullen,  L.L.P.  served  as  the   Company's
independent certifying accountants for the years ended  June  30,
1997  and  June  30,  1996.  The reports of McGladrey  &  Pullen,
L.L.P. contained no adverse opinion or disclaimer of opinion, and
were not qualified or modified as to uncertainty, audit scope, or
accounting  principals.   During the Company's  two  most  recent
years  there were no disagreements with accountants on any matter
of   accounting  principles  or  practices,  financial  statement
disclosure,  or  audit scope or procedure.   The  Company's  Form
10KSB   and  the  financial  statements  set  forth  therein   is
incorporated   herein   by  reference  and   delivered   to   the
shareholders herewith.  McGladrey & Pullen, L.L.P. expects to  be
present  at  the  Meeting, will have an  opportunity  to  make  a
statement if they so desire, and are expected to be available  to
respond to appropriate questions.
     
     The   Company's  Board  of  Directors  has  requested   that
McGladrey  Pullen,  L.L.P.  serve  as  the  Company's  certifying
accountants for the year ending June 30, 1998, and that firm  has
consented to so serve.

     vote  of Shareholders  at the  Company's  annual  meeting on
     February 27, 1996.

Employment Agreements
- ---------------------

     Effective July 26, 1995, the Company entered into long  term
employment agreements with a number of its executive officers and
extended  existing  employment  agreements  with  certain   other
officers.   The Company paid salaries in an aggregate  amount  of
$964,153  for all its officers and directors for the year  ending
June 30, 1997.

     Ronald  G.  Coss  currently serves as Vice Chairman  of  the
Company.  Mr. Coss had, prior to the merger of Micro Motors, Inc.
with  Pro-Dex, Inc., been compensated by Micro Motors at a salary
of  $560,000  for  the  fiscal year ending  March  31,  1995  and
$456,000 for the fiscal year ending March 31, 1994.  Annual  base
compensation  to  Mr.  Coss  under the  employment  agreement  is
$360,000  and is adjustable upward for inflation each July  1  of
the  five  year term of his employment agreement, for which,  for
the  year  ending June 30, 1997, compensation owed Mr.  Coss  was
$364,320, not including other benefits, payments or compensation.
However,  due  to  poor operating performance, in  February  1997
certain  management employees, to include Mr. Coss, agreed  to  a
temporary  reduction in base salary which reduction is  reflected
by  his  actual salary of $352,320 for the year ending  June  30,
1997.    Mr.  Coss'  employment  agreement  is  renewable   until
terminated.

     In addition to compensation to Mr. Coss under his employment
agreement,  the Company is obligated to pay Mr. Coss  $1  million
over  five  years,  commencing on July  26,  2001  under  a  Non-
Competition  Agreement in connection with  the  merger  of  Micro
Motors  with and into the Company's Micro subsidiary.   Upon  the
merger,  the  Company  also assumed two notes  payable  by  Micro
Motors  to Mr. Coss in the aggregate amount of $938,450, relating
to  termination of Mr. Coss' long term employment agreement  with
Micro Motors and prior unpaid earned compensation.  See "Item  12
- - Certain Relationships and Related Party Transactions."
     
     In  addition  to  the direct compensation  Mr.  Coss  is  to
receive under his employment agreement with the Company, he is to
have   reimbursement  of  reasonable  travel  and   entertainment
expenses,  a vehicle and auto expenses for business use,  country
club  dues and reasonable country club expenses, annual  physical
with a prior recuperative period and paid accommodations, and six
weeks  annual leave.  In the event Mr. Coss does not use  all  or
part  of  his  six  weeks annual leave, his employment  agreement
permits him to elect to be paid cash in lieu of leave not  taken.
Mr.  Coss  is required to reasonably forecast the amount  of  any
cash  in  lieu of leave, for purposes of the Company's  financial
forecasts.   Mr. Coss did not notify the Company that he  elected
to be paid cash in lieu of leave not taken during the year ending
June 30, 1997 and has indicated that he is unable to forecast his
leave for the year ending June 30, 1998.

     On  July  26,  1995, the Company entered  into  a  long-term
employment  agreement with Kent E. Searl,  its  Chairman.   Until
such  date,  Mr.  Searl  had received  no  compensation  for  his
services  to the Company, other than grant of options exercisable
at  the last bid price as of the date of grant.  During the  year
ended  June  30, 1995, Mr. Searl was granted options  to  acquire
50,000 shares of the Company's common stock, under the 1994 Stock
Option Plan.  On November 21, 1994, Mr. Searl was granted options
to  acquire  100,000  shares, under the 1994 Stock  Option  Plan,
exercisable  at  the last bid price on the date  of  grant.   Mr.
Searl  is  located  in  the  Company's  headquarters  offices  in
Boulder,  Colorado, and travels frequently to all  the  Company's
subsidiaries.  Under his employment agreement with  the  Company,
Mr.  Searl  was paid $150,000 for the year ended June  30,  1996.
His  salary under the employment agreement was to be $160,000 per
annum  through  June  30, 1997, however, due  to  poor  operating
performance,  Mr.  Searl  deferred  his  contract  right  to  the
increase  in  his compensation and further agreed to a  temporary
base  salary  reduction.  Compensation  due  Mr.  Searl  for  the
remaining year of the three year term of his employment agreement
is  $170,000  The  employment agreement accords Mr.  Searl  three
weeks  annual leave, but provides for no alternative of  cash  in
lieu  of  leave  untaken.   In addition, Mr.  Searl's  employment
agreement  provides that he may receive use of a car  at  Company
expense,  although  to  date  Mr.  Searl  has  received   limited
reimbursement for use of a vehicle not provided by  the  Company.
Mr.  Searl  is  also  entitled  to such  other  benefits  as  the
Company's  Board of Directors determines to offer  the  Company's
executive employees, and reimbursement of reasonable expenses.
     
     On July 26, 1995, Mr. Charles E. Strait entered into a long-
term  employment  agreement with the Company.  Pursuant  to  that
agreement,  Mr.  Strait's salary as the Company's  President  and
Chief  Operating  Officer for the year ending June  30  1997  was
$184,333.  That employment agreement also provides that,  upon  a
determination of disability, the Company is obligated to pay  Mr.
Strait for a period of ninety days until his disability insurance
coverage  commences.   Mr. Strait has made application  for  such
benefits and a determination of the same is pending.
     
     On  July  26,  1995, George J. Isaac began  serving  as  the
Company's  Vice  President and Chief Financial  Officer,  and  on
September  21,  1995  he  was elected  the  Company's  Secretary-
Treasurer  by  the  Board of Directors.  Mr.  Isaac  was  granted
options  to acquire 50,000 shares of the Company's common  stock,
exercisable  at the last bid price as of the date of grant,  upon
his  acceptance of employment, during the fiscal year ended  June
30,  1995,  but  received no other compensation  as  an  employee
during  such  year.   Mr. Isaac was granted  options  to  acquire
200,000  shares exercisable at the last bid price as of the  date
of  grant,  on November 21, 1995.  The employment agreement  with
Mr.  Isaac  provides that he is to receive a salary  of  $170,000
through  June  30, 1996, $180,000 July 1, 1996 through  June  30,
1997,  and $190,000 for the remainder of the three year  term  of
the  employment  agreement.  .  However, due  to  poor  operating
performance,  in February 1997 certain management  employees,  to
include Mr. Isaac, agreed to a temporary reduction in base salary
which  reduction  is  reflected by  his  actual  compensation  of
$171,000  for  the  year  ending  30  June  1997.   Mr.   Isaac's
employment  agreement allows three weeks annual  leave,  but  any
leave  not  taken  is to be forfeited without compensation.   The
employment agreement with Mr. Isaac provides that he may  receive
use of a Company vehicle for business purposes.  In addition, Mr.
Isaac is entitled to reimbursement of reasonable expenses at  the
discretion  of the Board of Directors and such other benefits  as
the  Board  of  Directors determines to  make  available  to  its
executive employees.
     
     On  August  1, 1993, the Company entered into an  employment
agreement  with  Mr.  Charles  L.  Bull,  President,  and   Chief
Operating  Officer  of  Challenge  Products.   Pursuant  to  that
agreement,  Mr.  Bull  is to be paid a base  salary  of  $100,000
annually  through December 31, 1998, with month to month  renewal
thereafter  unless  terminated on 60 days prior  written  notice.
Challenge Products is also required to maintain a $300,000 split-
dollar  life insurance policy on Mr. Bull, payable in  accordance
with  his direction.  The employment agreement provides that  Mr.
Bull  cannot compete, directly or indirectly, with Challenge  for
three years following termination of employment.
     
Compensation to Directors
- -------------------------

     Beginning  July 1, 1990, the Company established  a  fee  of
$1,000  per year for each director.  Through the year ended  June
30,  1995,  directors waived their fees.  During the  year  ended
June  30,  1995,  the three then serving directors  were  granted
options  to  acquire aggregate 150,000 shares in  recognition  of
substantial  efforts in obtaining the Micro and OMS acquisitions.
In  addition,  a  new  employee-director was granted  options  to
acquire  50,000 shares for his services in connection  with  such
acquisitions and to induce him to accept appointment to serve  as
the  Company's Chief Financial Officer.  In addition, during  the
year  ended June 30, 1995, the Company granted options to acquire
1,754 shares to Richard Reinhardt in accordance with the plan for
such options previously adopted by the Board with respect to non-
employee directors.  All such options are exercisable at the last
sale price on the date of grant.

     During  the year ended June 30, 1997, the Board of Directors
determined  that experienced outside directors expect to  receive
directors'  fees  and  stock  options  in  connection  with  such
service.   To that end, the Board of Directors adopted a proposal
to  pay  directors' fees for non-employee directors in the amount
of  $3,000  per  quarter, together with $1,000 for  each  regular
meeting  attended  by non-employee directors and  $500  for  each
committee  meeting  held on a date other  than  a  regular  board
meeting.   During the year ended June 30, 1997, $57,000 was  paid
as   non-employee  director  compensation.   Employee   directors
receive  only their usual salaries and expenses in attendance  at
Board  and  Committee  meetings  for  service  on  the  Board  of
Directors.   In  addition, in August 1996, the  Board  adopted  a
policy  to grant each non-employee director an option to purchase
20,000  shares of common stock upon commencement of their service
with  an  additional option granted automatically  each  year  to
purchase 10,000 shares.  The maximum term of such options is  ten
years.   During  the year ended June 30, 1997, Messrs.  Reinhardt
and  Hovee were each granted options to acquire 10,000 shares  of
the  Company's  common stock, under the Directors'  Stock  Option
Plan,  exercisable  at $3.55 share, pursuant  to  the  previously
adopted  plan  for  grant of options.  Mr.  Zaepfel  was  granted
options  to acquire 20,000 shares of the Company's common  stock,
under  the  Directors'  Stock Option Plan, exercisable  at  $2.44
pursuant to the previously adopted plan for grant of options.

1988 Stock Option Plan
- ----------------------

In  1988,  the  Company adopted its 1988 Stock Option  Plan  (the
"Plan")  pursuant to which the Company's Board of  Directors  was
authorized to issue options to purchase up to 150,000  shares  of
the   Company's   common  stock  to  employees,   directors   and
consultants of the Company.  The option exercise price must equal
fair  market value of the common stock on the date of grant.   No
options to purchase shares of common stock were granted under the
1988  Plan during the fiscal year ended June 30, 1997.   At  June
30,  1997,  options to purchase an aggregate of 25,000 shares  of
the  Company's common stock were outstanding under this Plan.   A
former director exercised options to purchase 30,000.  Options to
purchase  25,000 shares were exercised by a former consultant  to
the  company.  On July 5, 1996, the Company registered the shares
underlying  the options theretofore granted under the 1988  Stock
Option  Plan on a Form S-8 filed with the Securities and Exchange
Commission.

1994 Stock Option Plan
- ----------------------

     On May 25, 1994, the Company's shareholders adopted its 1994
Stock  Option Plan (the "Plan"), pursuant to which the  Company's
Option  Committee was authorized to issue options to purchase  up
to  500,000 shares of the Company's common stock to employees  of
the  Company.  At the Annual Meeting of shareholders on  February
27, 1996, the shareholders approved an increase in the number  of
shares  authorized for grant of options under  the  Plan  to  1.5
million  shares.   In  addition, the shareholders  also  approved
conversion  of  options to acquire shares of  Micro,  granted  to
Micro  employees prior to the acquisition to options  to  acquire
591,120 shares of the Company's common stock at an exercise price
of  $2.50 per share, under the 1994 Stock Option Plan.  The  1994
Stock  Option  Plan was adopted to advance the interests  of  the
Company   and   its  shareholders  by  affording   employees   an
opportunity  for  investment in the  Company.   The  Compensation
Committee  has sole discretion to select which employees  of  the
Company will be granted options, the number of shares subject  to
option, the timing of such option grants, when the options may be
exercised, and the exercise price.  The exercise price of options
must  be  at  least equal to the fair market value of the  common
stock  on the date of grant.  The maximum term of options granted
under  the  Plan is ten years.  As of June 30, 1997,  there  were
outstanding options under the 1994 Stock Option Plan  to  acquire
548,580 shares of the Company's common stock.

Directors' Stock Option Plan
- ----------------------------

     On  May  25,  1994, the Company's shareholders  adopted  its
Directors' Stock Option Plan (the "Plan") pursuant to  which  the
Company was authorized to issue options to purchase up to 200,000
shares of the Company's common stock to non-employee Directors of
the  Company.   At  the  February 26, 1996  Annual  Meeting,  the
Company's  shareholders approved an increase  in  the  number  of
shares authorized for grant of options under the Directors' Stock
Option  Plan to 500,000 shares.  The Plan was adopted to  advance
the  interests of the Company and its shareholders by  attracting
qualified   non-employee  Directors,  whose   participation   and
guidance  contribute to the successful operation of the  Company.
The  Board  of  Directors previously adopted a resolution,  which
provides  that options to purchase $5,000 share value  of  common
stock.   During  the  year  ended June 30,  1996,  the  Board  of
Directors determined that experienced outside directors expect to
receive  more substantial directors' remuneration in the form  of
fees and stock options in connection with their service.  To that
end,  the Board of Directors adopted a proposal to pay directors'
fees  for  non-employee directors in the  amount  of  $3,000  per
quarter,  together with $1,000 for each regular meeting  attended
by  non-employee  directors and $500 for each  committee  meeting
held  on a date other than a regular board meeting.  In addition,
in  August  1996,  the Board adopted a proposal to  grant  20,000
shares  to  non-employee  directors upon  their  commencement  of
service on the Board.  Mr. Zaepfel was granted options to acquire
20,000 shares of the Company's common stock, under the Directors'
Stock   Option  Plan,  exercisable  at  $2.44  pursuant  to   the
previously  adopted plan for grant of options.  The maximum  term
of  each  option is ten years.  As of June 30, 1997,  there  were
outstanding  options under the Directors' Stock  Option  Plan  to
acquire  315,856  shares  of  the  Company's  common  stock.    A
disinterested majority of the Board has committed, in furtherance
of  the  Board's  decision respecting the  remuneration  of  non-
employee  directors, automatic annual grants  in  the  amount  of
10,000  shares, to Messrs. Hovee, and Reinhardt, at the  exercise
price  of  $3.55,  effective upon the  resolution  of  the  Board
reflecting the foregoing.

Item 12.  Certain Relationships and Related Party Transactions

     In  1993,  when the Company acquired Challenge, Mr.  Charles
Bull  and Challenge entered into a royalty agreement and  license
agreement, both effective July 1, 1993 and extending to  December
31,   1998.   Under  the  license  agreement,  Mr.  Bull  granted
Challenge   Products   an  exclusive  license   to   manufacture,
distribute  and  market  a patented prophy  ring  in  return  for
execution  of the acquisition agreements and a royalty  agreement
providing for certain payments in respect of sales targets  never
achieved.   In  June 1996, Mr. Bull, the Company,  and  Challenge
entered  into  a letter agreement by which they agreed  that  the
royalty agreement was rescinded as void ab initio, for failure to
accurately  reflect the intent of the parties.  In addition,  the
parties  agreed that the exclusive paid up license  conferred  by
the license agreement should be evidenced by an assignment of all
rights in the prophy ring patent.  Mr. Bull continues to serve as
President  of  Challenge, and received  $113,276 in  compensation
for  his  services as President of Challenge, in the  year  ended
June 30, 1997.

     On  July  26, 1995, in connection with the merger  of  Micro
Motors  with and into Micro, the Company issued 3,350,000  shares
of  the Company's common stock in exchange for all the issued and
outstanding stock of Micro Motors, all as more fully described in
the  Company's  Form 8-K dated July 26, 1995.  The  Micro  Motors
Employee Stock Ownership Plan (the "Micro  ESOP") holds 1,075,359
of the shares issued in connection with the acquisition of Micro.
The number of shares owned  by  the  ESOP  has  been  adjusted to
reflect the correct allocation as between  the ESOP and remaining
shareholders  at the time of the merger.  The  number  of  shares
originally  allocated  to  the  ESOP was  erroneously  calculated
and reported as 1,099,805. The  ESOP has  certain limited  demand
registration rights in respect thereof, exercisable from July 26,
1996 through July 26, 1999, at the  expense of the Micro ESOP. In
addition,  the  Micro  ESOP  has  limited concurrent registration
rights,  sharing  costs  on  a  pro-rata  basis; in the event the
Company should undertake an underwritten  public  offering  prior
to July 26, 2002.  In addition,  shareholders  at  the  Company's
Annual  Meeting  on  February  27, 1996  approved  conversion  of
outstanding options of Micro  Motors Incentive  Stock Option Plan
into options to acquire 591,120 shares  of  the  Company's common
stock.

     Pursuant  to  the Merger Agreement, Ronald G.  Coss  entered
into  a Non-Competition Agreement pursuant to which he is  to  be
paid  $1 million over five years, with payment commencing in  the
sixth  year  after  closing.  In addition, Mr. Coss  executed  an
employment agreement with the Company, pursuant to which he is to
be  paid $360,000 annually as Vice Chairman of the Company  under
his   employment  agreement,  adjustable  upward  for  inflation,
representing  a reduction from the more than  $560,000  which  he
had  been  paid  as  the Chairman of Micro, despite  his  greater
responsibilities with the Company.  In addition  to  compensation
payable  under the employment agreement between the  Company  and
Mr.  Coss, he is entitled to certain executive employee  benefits
and perquisites.

     Prior to the merger transaction, Mr. Coss also entered  into
an  agreement to terminate his long term employment contract with
Micro  Motors,  for  an additional $677,400,  payable  over  five
years, at 11% interest per annum.  At the closing contemplated by
the   Merger   Agreement,  the  Company  assumed  Micro   Motor's
obligation  under the termination agreement, as well  as  Micro's
obligation  under  a  note for $261,050 in  prior  unpaid  earned
compensation.  In connection with the closing of the transactions
under  the  Merger  Agreement, the Company also  entered  into  a
flexible  Line  of Credit Loan Agreement, whereby  Mr.  Coss  may
borrow as much as $500,000 from the Company, at 7% interest, with
repayment  of the loan to occur as an offset of obligations  owed
by  the  Company  to  Mr. Coss in respect of the  Non-Competition
Agreement and employment agreement.

     In  connection  with  the acquisition of  OMS,  the  Company
borrowed  $500,000 from an unrelated third party  pursuant  to  a
Loan  Agreement and Promissory Note.  Fifty percent (50%) of  the
outstanding balance of obligations to the lender, at any time, is
jointly guaranteed by Professional Sales Associates, Inc. ("PSA")
and  Mr.  Kent E. Searl (the Company's Chairman).  In  connection
with  the  loan,  the lender was granted a ten  year  warrant  to
acquire  26,000 shares of the Company's common stock  exercisable
at  the  market price of the Company's shares at $2.50 per  share
exercise  price.   Warrants  to  acquire  13,000  shares  of  the
Company's  common stock were issued to PSA exercisable  at  $2.50
per  share.   Messrs. Kent E. Searl, Richard  N.  Reinhardt,  and
George J. Isaac, directors of the Company, are directors of  PSA.
No  warrants were issued to Mr. Searl.  The unrelated third party
loan, which PSA guaranteed, was repaid on July 26, 1996, when the
Company entered into a loan agreement with Harris Bank and Trust,
N.A.

     The  Company, prior to July 1, 1997, marketed certain of the
dental  equipment manufactured by Micro through PSA, a  firm  for
which  Messrs.  Searl, Reinhardt, and Isaac are  directors.   The
terms  and condition of the agreement with PSA were a continuance
of  the relationship between PSA and Micro Motors established  on
negotiated arms' length basis prior to the merger of Micro Motors
into  Micro.   Micro  Motors, Inc. dental  handpieces  previously
marketed  by  PSA  are currently being marketed  by  the  Biotrol
International, Inc. subsidiary of the Company, effective July  1,
1997.

     The  Company  leases its offices in Boulder,  Colorado  from
PSA,  a  firm for which Messrs. Searl, Reinhardt, and  Isaac  are
directors, as sub-lessees under a master lease between PSA and  a
third  party  unrelated  to  PSA or the  Company.   The  sublease
between  the Company and PSA is on a month to month  basis.   The
Company's monthly lease payments are  $1,883, which is  equal  to
the  amount of the lease payments due from PSA to the third party
lessor,  on  a  per square foot basis.  The Company's  management
believes  that the monthly rental is comparable to rents  charged
for  comparable properties in the market area.  Nevertheless, the
terms  of the sub-lease, including price, may not be as favorable
to  the Company as lease terms, which might have, been negotiated
with a third party in an arm's length transaction.

     Micro leases its offices and manufacturing facility in Santa
Ana, California from Ronald G. Coss, currently a director of  the
Company,   at  a  monthly  rental  of  $28,237.   The   Company's
management  believes  that the monthly rental  is  comparable  to
rents  charged  for  comparable properties in  the  market  area.
Nevertheless, the terms of the lease, including price, may not be
as  favorable  to the Company as lease terms, which  might  have,
been   negotiated  with  a  third  party  in  an   arm's   length
transaction.

     On October 10, 1995, the Company granted warrants to acquire
100,000  shares  to  Mr. Carl Militello, pursuant  to  a  Warrant
Agreement  between Mr. Militello and the Company.  Such  warrants
are exercisable at the last bid price as of the date of grant  of
$2.13.   Such  warrants  were  issued  as  consideration  to  Mr.
Militello  for  services  to  the  Company,  including   investor
relations  and financial consulting services.  Mr.  Militello  is
not a related party.
     
     On  July  5, 1996, the Company filed a Form S-8 to  register
the shares of common stock underlying options theretofore granted
pursuant  to  its  1988 Employee Stock Option  Plan.   Dr.  Kyle,
President  of  DCM  and a former director of  the  Company,  held
30,000  of such  options,  all of which were exercisable at $0.25
per share.
