                                   ----------
                             MEDICAL DYNAMICS, INC.

                         523,834 Shares of Common Stock
                       Offered for Resale by a Shareholder

     Resonance  Limited,  a  shareholder,  is offering  up to 523,834  shares of
Medical Dynamics,  Inc. common stock for sale.  Resonance  acquired these shares
from  us for  $800,000  in  March  1999.  Our  common  stock  is  traded  in the
over-the-counter  market and is quoted on the Nasdaq  SmallCap  Market under the
symbol "MEDY." On April 9, 1999,  Nasdaq  reported that the closing price of our
Common Stock was $2.00 per share.

         We will not receive any money from Resonance's  sale of the shares.  We
will  pay  all  expenses  incurred  in  connection  with  this  offering  except
commissions  and discounts which  Resonance will pay to  underwriters,  dealers,
brokers or agents.

         Resonance has advised us that it has made no  commitments  with respect
to the sale of the shares, but that it may sell the shares from time-to-time

o        on the Nasdaq SmallCap Market;
o        in the over-the-counter market outside of Nasdaq; or
o        in negotiated transactions other than the Nasdaq SmallCap Market or the
         over-the-counter market.

Any of these sales may involve block transactions. Resonance has advised us that
it may sell the Shares at market prices at the time of sale,  at prices  related
to prevailing market prices at the time of sale, or at other negotiated prices.

This Investment  Involves a High Degree of Risk. You Should Purchase Shares Only
If You Can Afford a Complete Loss.  See "Risk  Factors"  Beginning on Page 5. We
have not authorized  anyone to give  information  or to make any  representation
other than as  contained  in this  prospectus  in  connection  with the offering
described herein.

                               PROSPECTUS SUMMARY

     You should  read the  following  summary  together  with the more  detailed
information  regarding  our  company  and the  common  stock  being  offered  by
Resonance as the selling  shareholder,  as well as our financial  statements and
notes to those  statements  appearing  elsewhere in this  prospectus  and in the
documents incorporated by reference.

Medical Dynamics, Inc

     We are engaged in the design,  development,  manufacture  and  marketing of
medical and dental video cameras and related  disposable  products for a variety
of professional  specialties.  Our principal products are small, color,  medical
and dental  video  camera  systems  for use in  patient  diagnosis  and  various
surgical  procedures.  We have been  manufacturing  similar cameras since August
1981.  When  used in this  prospectus,  the terms  "we" and  "our"  refer to our
company, Medical Dynamics, Inc.

     In  October  1997 we  acquired  Computer  Age  Dentist,  Inc.  ("CADI"),  a
California corporation based in Los Angeles, California. CADI develops and sells
practice  management  software  and  related  electronic  services to the dental
profession. In February 1998, through CADI, we acquired Information Presentation
Systems,  Inc. of Marietta,  Georgia,  at that time one of the nation's  largest
suppliers  of  customized  multimedia  systems  for use in a  variety  of dental
operatory environments. In April 1998, through CADI the Company acquired Command
Dental  Systems of  Farmington  Hills,  Michigan,  which  develops  and  markets
turn-key computer systems for the efficient management of dental practices.

     Our principal  executive  offices and  manufacturing  facilities  are at 99
Inverness Drive East, Englewood,  Colorado,  80112. Our telephone number at that
address is (303) 790-2990.

     Resonance,  the  shareholder  which is selling the shares  pursuant to this
prospectus, is offering up to 523,834 shares of our common stock (the "Shares").
Resonance  will  receive  all of the  proceeds  from the  offer  and sale of the
Shares. We will receive no cash proceeds from any sale Resonance may make.

     We will pay the costs related to the  registration  statement in which this
Prospectus is included. Resonance will pay its own expenses related to the offer
and sale of the Shares, including any underwriter discounts or commissions.

                                  RISK FACTORS

     Investment  in the shares of common stock offered in this  prospectus  (the
"Shares")  involves a high degree of risk.  You should  consider  the  following
discussion of risks as well as other  information in this  prospectus and in the
documents incorporated by reference before purchasing any Shares.

     1.  Losses  from  Operations.  We have a history of net  operating  losses,
which, when accumulated,  total $20,792,400 through December 31, 1998. These net
operating  losses have resulted in working capital  shortages from time to time.
We can offer no  assurance  that we will be able to  operate  profitably  in the
future.  The risks described in this section must be considered when judging the
likelihood that we may achieve profitable operations in the future.

     2. Working Capital  Shortages and Dependence on Third Party  Financing.  We
have regularly  incurred working capital  shortages and have sought to alleviate
these shortages  through debt and equity  financing  provided by third party and
affiliated investors, which have been accomplished at prices significantly below
the market price concurrently quoted on Nasdaq.

     Although we have been  successful  in the past  raising  necessary  working
capital,  we cannot  offer any  assurance  that these  sources  of capital  will
continue to be available on terms which are acceptable to us. Eventually we will
be required to finance our operations  with our cash flow, and we are attempting
to increase our revenues in an effort to do so.

     We cannot offer you any assurance,  however,  that our past working capital
shortages  will not continue and may not  adversely  affect our ability to raise
additional debt or equity capital in the future, if necessary.

     3. Risk of  Dilution.  We have sold our common  stock at  discounts  to the
market price existing at the time of the sale. We may do so again in the future,
although  there are no plans to do so at present.  We have  several  obligations
outstanding  which may result in further  dilution  to  shareholders,  including
persons who may purchase the shares described in this prospectus:

     Convertible Debentures.  There are approximately  $1,300,000 of convertible
debentures  outstanding.  These  debentures  are  convertible  at 85% of "Market
Price."  "Market Price" is defined to mean the average of the two lowest closing
bid prices of the Common  Stock as reported by The Nasdaq  Stock Market over the
60 trading day period  immediately  preceding  the  determination  date.  If the
debentures were entirely  converted on April 9, 1999, we would cancel $1,300,000
of debt in  exchange  for the  issuance  of 977,444  shares of our Common  Stock
(approximately  $1.33 per share).  The issuance of these  shares,  if any,  will
result in dilution to our shareholders at a time when the quoted market price of
our shares is significantly higher.

     Additional Shares. We also have an obligation to issue additional shares to
Resonance.  The  additional  shares are  intended to  compensate  Resonance  for
one-third  of any  decrease in the public  market  price of our Common  Stock on
_________,  1999, ______,  1999, and __________ (two, four, and six months after
the date of this  prospectus).  The issuance of these shares,  if any, will also
result in dilution to our shareholders.

                                       -8-

<PAGE>


     Market Impact.  We anticipate  that the sales of our Common Stock following
the conversion of the debentures,  and by Resonance have had and may continue to
have in the future a negative impact on the market for the Common Stock. We also
believe  that perhaps  even the  possibility  of these sales may have a negative
impact on the market for our Common Stock.

     4. Product  Liability.  We could be subject to claims for personal injuries
resulting  from the use of our  products.  Although we carry  product  liability
insurance coverage in amounts we believe are commercially  reasonable within the
medical products industry, there can be no assurance that the amount of coverage
would be  sufficient  to cover any proven  claims.  We would be  materially  and
adversely  affected if any damages were awarded in amounts  which were in excess
of our coverage limits.

     5.  Acquisition of New  Businesses.  During the fiscal year ended September
30, 1998, we acquired three new  businesses,  Computer Age Dentist,  Information
Presentation  Systems,  and Command Dental Systems. We believe that we have been
generally  successful  in our efforts to  integrate  these  businesses  into our
business. We are, however, seeking to resolve certain issues with respect to the
Command  Dental  acquisition.  Following the  completion  of the Command  Dental
acquisition,  certain of the principals appear to have violated  confidentiality
and non-competition provisions. We believe that the former principals of Command
Dental  encouraged  certain  former  employees  of Command  Dental  (who  became
employees of Computer Age Dentist) to violate their employment  obligations.  In
addition,  the  operations  of the  Command  Dental  assets  did not  conform to
representations  made to us.  Although  we  have  commenced  litigation  on this
matter,  we are also  negotiating  with the former Command Dental  principals to
resolve the issues identified.  Although we are disappointed with the situation,
we do not believe that any resolution will have a material adverse effect on us,
our business operations or our financial condition as a whole.

     6.  Limitations on Ability to Obtain  Additional  Financing.  Our agreement
with the holder of the convertible debentures ("Tail Wind") contains limitations
on our ability to raise additional capital.  These restrictions prohibit us from
raising  working capital or other equity  investment in  transactions  where the
purchase   price  of  the  securities  is  to  be  adjusted  for  future  market
fluctuations (known as "variable rate transactions") until at least August 1999.
However,  we believe that we will be able to work within these  restrictions  to
the extent we need additional capital.

     7. Technological Change and Risk of Technological Obsolescence. The medical
products  segment and the dental  products  segment,  our two principal lines of
business,   are  subject  to  rapid  and   significant   technological   change.
Accordingly, our viability will be dependent in part on our ability to introduce
competitive  products  to the  marketplace  in a timely  manner and  enhance and
improve such products to the  satisfaction  of our  customers.  We cannot assure
that we will be able to keep pace with  technological  developments  or that our
products will not become obsolete.

     8.  Competition.  Our  operations  and product  lines are subject to a high
level of competition from foreign,  as well as domestic,  manufacturers of color
medical and dental video  cameras and other  medical  devices which we currently


                                       -9-

manufacture  and  sell,  or  which we may  develop  in the  future.  Some of our
competitors are affiliated with large  companies with  substantial  economic and
personnel  resources  which  greatly  exceed  our  resources.  We can  offer  no
assurance that we will be able to compete successfully with other companies.

     In  addition,  there are a large  number of  competitors  in  Computer  Age
Dentist's dental practice management area. Most of these competitors are smaller
businesses.  Computer  Age  Dentist's  software  is Y2K  compliant,  unlike  the
software offered by some of our competitors. There can be no assurance, however,
that  competitors may not reduce our market share by offering their  proprietary
version of dental practice management software. Through Computer Age Dentist, we
plan to compete with other  businesses by continuing to upgrade  software and by
continuing to package the dental practice software with a complete office system
of hardware and software and diagnostic equipment.

     9. Potential Conflicts  of Interest.  There have been significant conflicts
of  interest  in our  operation  and  management.  These  conflicts  include our
purchase of certain  equipment  and patents  from our  directors  and  executive
officers, granting of royalties, loans made available to us by our Chairman, and
our  employment of sons of two of our  directors.  These  transactions  were not
negotiated at arms' length, although the Board of Directors believes that all of
these transactions were fair and in our best interests. Although we use our best
efforts to minimize  conflicts of interest,  the existence of such conflicts may
impact us in our business activities.

     10. Dependence on Management. At present, our success is dependent upon the
active  participation  of our existing  management,  our Chairman and  principal
shareholder,  Dr.  Adair,  and our Chief  Executive  Officer,  Van Horsley,  Dr.
Adair's step-son. We do not have employment contracts with either Mr. Horsley or
Dr. Adair.

     Computer  Age  Dentist's  operations  are  significantly  dependent  on the
continued  availability  of the services of Daniel L.  Richmond and Chae U. Kim.
Both  Messrs.  Richmond and Kim are subject to five year  employment  agreements
which expire in October 2002.

     The loss of the  services  of any of these  persons  would  have a material
adverse  effect on us and our  operations.  In the event of such a loss,  we can
give no assurance that we could replace any person without incurring substantial
additional expense.

     11.  Government  Regulation.  Because  certain  of  the  products  that  we
manufacture are used in surgery and other medical applications,  agencies of the
federal  government,  including the FDA,  regulate and closely  scrutinize these
products.  Although we believe that our  facilities  are in compliance  with all
applicable regulations, we can offer no assurance that we will be able to comply
fully  with all of the  government  regulations  to  which  our  operations  are
subject.  Failure to comply strictly with all FDA requirements (not all of which
are  written)  may  result  in  sanctions  as  severe  as the  cessation  of our
manufacturing business.  Although we have had difficulty in certain instances in
the past in obtaining FDA approval on new products,  our current business in not
materially  dependent on this issue and,  therefore,  this is not deemed to be a
significant risk.


                                      -10-

     12.  Protection of Technology.  Although we obtain secrecy  agreements from
our  employees  and others  having  access to our trade  secrets  and from those
persons  holding  patents on  certain of our  technology,  such  agreements  and
patents do not afford complete  protection  against the unauthorized use of such
information by others.  Furthermore,  the costs of  prosecuting  persons who may
accidentally  or  intentionally  infringe  on our  patents or divulge  our trade
secrets can be expensive and time consuming.

     The  unauthorized  use of our trade  secrets  and the  infringement  of its
patents could have a material  adverse  effect on us and on Computer Age Dentist
and our ability to compete.

     13.  Significant  Investment  in  Intangible  Assets.  As a  result  of the
acquisitions  of Computer Age Dentist,  Information  Presentation  Systems,  and
Command Dental System,  we have a significant  investment in intangible  assets,
amounting to approximately  $5,945,100 at December 31, 1998 (64% of MEDY's total
assets).  There are two risks  associated  with our  significant  investment  in
intangible assets:

         The expenses  associated with the annual amortization of the intangible
         assets will make it more difficult for us to realize net income.

         Because intangible assets are incapable of precise valuation, it may be
         necessary for us to reduce the balance sheet  valuation of these assets
         at some later point, although we have no intention or basis to do so at
         the present time.

     14. Limited Public Market; Price Volatility; and No Assurance of Liquidity.
There  currently is a limited  public  market for our Common  Stock.  The public
market for our common  stock is highly  volatile,  both as to price and  trading
volume.  Factors such as those discussed in this "Risk Factors" section may have
a significant impact on the market price of the securities  offered.  Also, some
brokerage  firms may not effect  transactions  in securities  that trade below a
stipulated  price,  and most  lending  institutions  will not  permit the use of
low-priced or thinly traded securities as collateral for loans.

     15. No Dividends  Paid or  Contemplated.  We have never paid any dividends,
and we do not expect to pay any dividends in the foreseeable  future.  Investors
who  anticipate  the  need for  either  immediate  or  future  income  by way of
dividends from their  investment,  should not purchase the Shares made available
in this Offering.  Our lending  arrangements with Norwest Business Credit, Inc.,
significantly restrict our ability to pay dividends.

     16. Year 2000  Compliance.  Although  there can be no assurance,  we do not
anticipate that we will suffer any adverse impact as a result of Year 2000 (Y2K)
computer software issues, either as a result of third party non-compliance or as
a result of internal  matters.  The Y2K issue is the result of  computer  system
programs  being written for two digits rather than four to define the applicable
year.  As a result,  date-sensitive  software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in system failures or
miscalculations, causing disruption of normal business activities.

     None of the information  technology or other software and hardware  systems
which we use  (including  our  subsidiary,  Computer Age  Dentist)  incorporates
technology  that is incapable  of  recognizing  dates beyond  December 31, 1999.
Computer  Age Dentist,  through our internal  staff,  has  developed  our dental
practice  management software for the Windows platform and,  consequently,  such
software  recognizes  dates beyond December 31, 1999. While Computer Age Dentist
is still  supporting some software which is DOS-based or which otherwise may not
be Y2K  compliant,  we have advised the  customers  using this software of their
need to upgrade their office software in anticipation of Y2K. Even if we were to
provide the necessary  software  upgrade to these customers at no cost (which we
do not have an  obligation  to do), the total loss would be less than $60,000 in
revenues and is not  considered to be material.  Computer Age  Dentist's  dental
practice management software is Y2K compliant.  We believe that this offers us a
marketing  opportunity in that some of our competitors' software currently being
utilized by dental  offices is not Y2K compliant and will need to be replaced by
those offices before December 31, 1999. We cannot offer any assurance,  however,
that these offices purchase our dental practice  management  software to replace
their systems.

     In  making  the  foregoing  determination,  we  assessed  embedded  systems
contained in our office buildings,  equipment,  and other infrastructures.  As a
result,  we have  not  established  a  contingency  plan in the  event  of a Y2K
catastrophe,  and we do not believe that such a plan is necessary. Of course, we
are all dependent on facilities outside of our control, such as electrical power
supplies, banking facilities,  transportation facilities (such as airlines), and
communications  facilities.  While we  believe,  based  on  public  reports  and
notifications  we received,  that these  outside  facilities  are or will be Y2K
compliant,  we have  no  other  basis  for  determining  their  compliance.  Our
operations would be significantly and adversely affected if any of these outside
facilities are adversely  affected by the  millennium  change or by other issues
related to Y2K.


                                 USE OF PROCEEDS

     Resonance,  as the selling shareholder,  will receive all proceeds from the
sale of the Shares  offered and sold under this  Prospectus.  We will receive no
proceeds.


                                   THE COMPANY

     Our corporate  name is "Medical  Dynamics,  Inc." We were  incorporated  in
Colorado in March 1971. We are engaged in the design,  development,  manufacture
and  marketing  of medical  and dental  video  cameras  and  related  disposable
products for a variety of professional  specialties.  Our principal products are
small,  color,  medical  and  dental  video  camera  systems  for use in patient
diagnosis and various  surgical  procedures.  We have been  manufacturing  these
types of cameras since August 1981.

     In October  1997,  we acquired  100% of the  outstanding  capital  stock of
Computer  Age Dentist,  Inc.,  based in Los  Angeles,  California.  Computer Age
Dentist is engaged in the development and sale of practice  management  software
and related electronic services to the dental profession.

                                      -12-

     In February 1998,  through  Computer Age Dentist,  we acquired  Information
Presentation Systems, Inc. of Marietta, Georgia ("IPS"). IPS supplied customized
multimedia systems for use in a variety of dental operatory environments.

     In April 1998,  also  through  Computer Age  Dentist,  we acquired  Command
Dental Systems of Farmington Hills, Michigan ("Command").  Command developed and
marketed  turn-key  computer  systems  for the  efficient  management  of dental
practices.  During the period following our acquisition of Command, we developed
some significant  concerns about the information provided to us when we made our
decision to acquire Command,  and we have sought  rescission of that transaction
and damages.  We are seeking to  negotiate a resolution  of this matter with the
former  principals of Command whom we believe  responsible for the  transaction.
Although  this  matter is in only the  early  stages  of  resolution,  we do not
believe it will have any material  impact on us, our business,  or our financial
condition.  The assets acquired from Command made an immaterial  contribution to
our  revenues  in the  current  fiscal  year  and  are  not  expected  to make a
significant contribution in the future, even if we were to retain Command.

     In reviewing  our financial  statements  which are  incorporated  herein by
reference,  it should be noted that a  substantial  portion of our  revenues for
fiscal 1998 were derived from the businesses we acquired  during fiscal 1998 and
not from our historical  businesses of medical and dental camera  manufacturing.
For example,  our revenues  during fiscal year 1998 (ending  September 30, 1998)
totaled approximately $7,847,000;  of that amount,  approximately $7,575,000 was
attributable to business  generated as a result of the  acquisitions of Computer
Age Dentist, IPS and Command ($671,556 attributable to Command).

     Our principal executive offices and manufacturing facilities are located at
99 Inverness Drive East,  Englewood,  Colorado,  80112.  Our telephone number is
(303) 790-2990.


                               SELLING SHAREHOLDER

     The  selling   shareholder  under  this  prospectus  is  Resonance  Limited
("Resonance"). Resonance is not one of our affiliates; neither Resonance nor any
affiliate of Resonance has any position,  office or other material  relationship
with us for more than the past  three  years.  The  following  table  sets forth
certain information about Resonance's ownership of our common stock:

     Based on  information  Resonance has given to us,  Resonance  does not own,
directly or  indirectly,  any other shares of our Common Stock.  Resonance  does
have the right to obtain  additional shares of our common stock and a warrant to
purchase our common stock for six months after the date of this Prospectus. That
right is wholly dependent on market conditions.

     On _______,  1999, _______,  1999, and _______ (two months, four months and
six  months  after the date of this  prospectus)  we may be  obligated  to issue
additional  shares to  Resonance  if the per share market price is less than the
$1.526 Resonance paid for the shares included in this prospectus. The "per share
market  price" shall mean the average  closing bid price for the 20 trading days
immediately  preceding  the date on which  the  price is to be  determined.  The
number of additional shares which we may be obligated to issue to Resonance will
be calculated  pursuant to a formula set forth in our agreement with  Resonance,
which can best be  explained by the  following  example  (assuming  that the per
share market price on the first determination date is $1.10 per share):

$223,782.60 difference / 3 / $1.10               =      67,813 additional shares to be issued to
                                                        Resonance.
</TABLE>


     In addition,  on  ___________,  we must issue warrants to purchase  523,834
shares of our common stock. In order to acquire the shares,  Resonance will have
to pay us $1.526 per share. The warrants will expire on _________,  2000 (twelve
months after the date of this  prospectus).  We have agreed with  Resonance that
the total number of additional shares plus the total number of warrants will not
exceed 2,060,033  shares.  Resonance has agreed to reduce the number of warrants
to  ensure  that  this  limitation  (which  we  refer to as the  "future  priced
securities limitation") is not exceeded.

                              PLAN OF DISTRIBUTION

     Resonance has advised us that it may offer and sell their Shares at various
times in one or more of the following types of transactions:

o        on the Nasdaq SmallCap Market;
o        in the over-the-counter market outside of Nasdaq; or
o        in negotiated transactions other than the Nasdaq SmallCap Market or the
         over-the-counter market.

     Any of the foregoing may involve block transactions.  Resonance has advised
us that it may sell the Shares at market  prices at the time of sale,  at prices
related to prevailing  market prices at the time of sale, or at other negotiated
prices.

     Resonance  has also  advised us that it may use  brokers or dealers to sell
the Shares, and that the brokers or dealers may act as agents for Resonance,  or
as  principals  in the  transaction.  If this  happens,  Resonance  will pay the
discounts or commissions  for the brokers or dealers,  or the brokers or dealers
may  receive  commissions  from  purchasers  for whom  they  acted as  agents or
principals.

     If  Resonance  gives or pledges  the shares to  another  person,  the other
person may sell the shares as a Selling  Shareholder under this Prospectus.  Any
Shares that  qualify for sale under Rule 144 of the  Securities  Act may be sold
under such rule rather than pursuant to this Prospectus.

     In  effecting  sales,  brokers or dealers may arrange for other  brokers or
dealers to  participate.  Such  broker or dealers  may  receive  commissions  or
discounts from Resonance in amounts to be negotiated by it.  Resonance may enter
into hedging  transactions  with brokers or dealers.  The brokers or dealers may
engage in short sales of the Common Stock in the course of hedging the positions
assumed with Resonance  (including,  without limitation,  in connection with the
distribution of the Common Stock by such brokers or dealers). Resonance may also
engage in short  sales of the Common  Stock and may enter  into  option or other
transactions  with  brokers or dealers  that  involve the delivery of the Common
Stock to the brokers or dealers,  who may then resell or otherwise transfer such
Common  Stock.  Such brokers or dealers and any other  participating  brokers or
dealers may, in connection with such sales, be deemed to be underwriters  within
the  meaning  of the  Securities  Act of 1933,  as  amended.  Any  discounts  or
commissions  received  by any  such  brokers  or  dealers  may be  deemed  to be
underwriting  discounts and  commissions  under the  Securities  Act of 1933, as
amended.

     We will pay all of the expenses incident to the filing of this Registration
Statement,  which we estimate to be $20,000.  These  expenses  include legal and
accounting fees in connection with the preparation of the Registration Statement
of which this Prospectus is a part,  legal and other fees in connection with the
qualification  of the sale of the Shares  under the laws of  certain  states (if
any),  registration  and filing fees,  printing  expenses,  and other  expenses.
Resonance will pay all other  expenses  incident to the offering and sale of the
Shares to the public,  including  commissions  and  discounts  of  underwriters,
brokers, dealers or agents, if any.


                                      -15-

     We have  agreed to use our best  efforts  to keep the  registration  of the
Shares  offered  hereby  effective  until the date upon  which all of the Shares
offered by Resonance have been sold.

                            DESCRIPTION OF SECURITIES

     Our articles of  incorporation  authorize us to issue two classes of stock:
Common Stock and Preferred  Stock. The following  generally  describes these two
classes.

Common Stock

     Authorized.  We are authorized to issue 30,000,000  shares of Common Stock.
Each  holder of a share of Common  Stock gets one vote per share on all  matters
submitted to a vote of shareholders, but may not cumulate votes for the election
of directors. Accordingly, the holders of more than 50% of the shares voting for
the election of directors  can elect 100% of the  directors if they choose to do
so; and, in such event, the holders of the remaining less than 50% of the shares
voting for the election of the  directors  will be unable to elect any person or
persons to the Board of Directors.  Holders of Common Stock also are entitled to
receive  ratably such dividends as may be declared by the Board of Directors out
of  funds  legally  available  therefor.   In  the  event  of  our  dissolution,
liquidation or winding up, holders of common stock are entitled to share ratably
in all  assets.  Holders  of  Common  Stock  have no  preemptive,  subscription,
redemption or conversion  rights. All the outstanding shares of Common Stock are
fully paid and nonassessable.

     Issued and Outstanding.  On March 31, 1999, MEDY had issued and outstanding
10,851,270  shares of Common Stock. We may issue additional  shares to Resonance
as is discussed above,  and we will likely issue additional  shares to Tail Wind
Fund, Ltd. for conversion of outstanding convertible  debentures,  in payment of
interest or on exercise of outstanding  warrants  (estimated to be not more than
an additional 1,779,000 shares). The number of additional shares and warrants to
be issued to Resonance  will not be  determined  until at least six months after
the date of this Prospectus.  In addition,  on March 31, 1999, we were obligated
to issue an additional 75,000 shares to Merchant  Capital,  Inc., on exercise of
an option to purchase our Common Stock it held.

     On March 31, 1999,  we also had  outstanding  stock  options to purchase an
additional  4,483,037  shares of Common  Stock  exercisable  at exercise  prices
ranging  between  $1.00 and $4.50 per share.  Certain of these  options are only
exercisable upon the Company achieving certain performance goals.

     Dividends.  Holders of our Common Stock are entitled to dividends  when, as
and if  declared  by the  Board  of  Directors  out of funds  legally  available
therefor, subject to the rights, if any, of holders of any outstanding shares of
Preferred  Stock. We have not declared or paid any dividends on Common Stock and
we do  not  anticipate  that  we  will  declare  or  pay  any  dividends  in the
foreseeable  future. Our agreement with Norwest Business Credit,  Inc. precludes
us from declaring any dividends.


                                      -16-

<PAGE>



Preferred Stock

     We are also authorized to issue up to 5,000,000  shares of Preferred Stock,
and we may do so in series which may be designated by the Board of Directors. We
have not issued any shares of Preferred Stock and we do not contemplate  issuing
any shares of Preferred Stock in the immediate  future;  however,  the Board may
use its ability to issue Preferred  Stock as it deems  appropriate to effect our
business purposes.

     Our Board of Directors  will  determine the material terms of any series of
Preferred Stock without shareholder  approval.  These terms may include dividend
rate,  conversion  features and voting rights.  Our Board will  determine  these
terms at the time of issuance. The ability of our Board to issue Preferred Stock
may also be used as a means of  resisting  a change of control  and,  therefore,
could be considered an "anti-takeover" device.

Transfer Agent

     The transfer  agent for our Common Stock is  Continental  Stock  Transfer &
Trust Co., 72 Reade Street, New York, New York 10007.

                                  LEGAL MATTERS

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.


         The  following is an  itemization  of all  expenses  (subject to future
contingencies)  incurred or to be incurred by the Registrant in connection  with
the issuance and distribution of the securities being offered.  All expenses are
estimated except the registration fee.


         Registration and filing fee                                 $   292
         Printing                                                      1,000

Item 15. Indemnification of Directors and Officers.

     Section  7-109-102 of the Colorado  Revised  Statutes and the  Registrant's
Articles  of  Incorporation,   under  certain   circumstances  provide  for  the
indemnification of the Registrant's officers,  directors and controlling persons
against liabilities which they may incur in such capacities.  A summarization of
the  circumstances  in which such  indemnification  is provided for is contained
herein,  but that  description  is qualified in its entirety by reference to the
Registrant's  Articles of Incorporation and the relevant Section of the Colorado
Revised Statutes.

     In general,  the statute  provides  that any  director  may be  indemnified
against  liabilities  (including the  obligation to pay a judgment,  settlement,
penalty,  fine or  expense),  incurred  in a  proceeding  (including  any civil,
criminal  or  investigative  proceeding)  to which the  director  was a party by
reason of status as a director.  Indemnity  may be  provided  if the  director's
actions  resulting in the liabilities:  (i) were taken in good faith;  (ii) were
reasonably  believed to have been in the Registrant's best interest with respect
to actions taken in the  director's  official  capacity;  (iii) were  reasonably
believed not to be opposed to the  Registrant's  best  interest  with respect to
other actions; and (iv) with respect to any criminal action, the director had no
reasonable grounds to believe the actions were unlawful.  Unless the director is
successful upon the merits in such an action,  indemnification  may generally be
awarded  only  after a  determination  of  independent  members  of the Board of
Directors or a committee thereof, by independent legal counsel or by vote of the
shareholders that the applicable  standard of conduct was met by the director to
be indemnified.

     The  statutory   provisions  further  provide  that  unless  limited  by  a
corporation's  articles  of  incorporation,  a director or officer who is wholly
successful,  on the merits or otherwise,  in defense of any  proceeding to which
the  director  or officer as a party,  is  entitled  to receive  indemnification


                                      -19-

<PAGE>



against reasonable  expenses,  including attorneys' fees, incurred in connection
with the  proceeding.  In  addition,  a  corporation  may  indemnify  or advance
expenses  to an  officer,  employee  or agent who is not a director to a greater
extent than permitted for  indemnification of directors,  if consistent with law
and if provided for by its articles of incorporation,  bylaws, resolution of its
shareholders or directors or in a contract.  The provision of indemnification to
persons  other than  directors  is subject to  limitations  as may be imposed on
general public policy grounds.

     In addition to the foregoing,  unless limited by the Registrant's  articles
of incorporation,  a court,  upon petition by an officer or director,  may order
the Registrant to indemnify the officer or director against  liabilities arising
in connection with any  proceeding.  A court may order the Registrant to provide
indemnification,  whether or not the  applicable  standard of conduct  described
above was met by the officer or director.  To order  indemnification,  the court
must  determine  that the  petitioner  is  fairly  and  reasonably  entitled  to
indemnification  in light of the  circumstances.  With  respect  to  liabilities
arising as a result of proceedings on behalf of the Registrant, a court may only
require that a petitioner be indemnified as to the reasonable expenses incurred.
The Registrant has entered into  indemnification  agreements with certain of its
directors  agreeing to provide  indemnification  benefits to the fullest  extent
permitted by Colorado law and its articles of incorporation and bylaws.

     Indemnification  in connection  with a proceeding by or in the right of the
Registrant in which the director is  successful,  is permitted only with respect
to  reasonable  expenses  incurred  in  connection  with the  defense.  In these
actions, the person to be indemnified must have acted in good faith, in a manner
believed to have been in the  Registrant's  best interest and must not have been
adjudged  liable for  negligence  or  misconduct.  Indemnification  is otherwise
prohibited in connection  with a proceeding  brought on behalf of the Registrant
in which a director is adjudged liable to the Registrant,  or in connection with
any proceeding  charging  improper personal benefit to the director in which the
director is adjudged liable for receipt of an improper personal benefit.

     Colorado law  authorizes  the  Registrant  to  reimburse or pay  reasonable
expenses incurred by a director, officer, employee or agent in connection with a
proceeding,  in  advance  of a final  disposition  of the  matter.  Advances  of
expenses  are  permitted  if the person  furnishes  to the  Registrant a written
statement of his belief that he met the applicable  standard of conduct required
to permit indemnification. The person seeking expense advances must also provide
the  Registrant  with  a  written  agreement  to  repay  the  advances  if it is
determined the applicable  standard of conduct was not met. A determination must
also be  made  that  the  facts  known  to the  Registrant  would  not  preclude
indemnification.

     The statutory section cited above further specifies that any provisions for
indemnification  of or advances for expenses to directors which may be contained
in the  Registrant's  Articles  of  Incorporation,  Bylaws,  resolutions  of its
shareholders  or directors,  or in a contract  (except for  insurance  policies)
shall be  valid  only to the  extent  the  provisions  are  consistent  with the
Colorado  statutes and any  limitations  upon  indemnification  set forth in the
Articles of Incorporation.

                                      -20-

<PAGE>



     The statutory provision cited above also grants the power to the Registrant
to purchase and maintain insurance policies which protect any director, officer,
employee,  fiduciary or agent against any liability asserted against or incurred
by them in such  capacity  arising out of his status as such.  The  policies may
provide for indemnification  whether or not the corporation would otherwise have
the power to provide  for it.  The  Registrant  has not  obtained  any  policies
providing  protection against liabilities imposed under the securities laws. The
registration rights agreements dated July 31, 1998, and October 31, 1997 between
the  Registrant  and  Tail  Wind.,  provide  for  cross  indemnification  by the
Registrant and Resonance, in certain circumstances, including certain securities
laws violations.

Item 17. Undertakings.

     The  undersigned  Registrant  hereby  undertakes:  (1) to file,  during any
period in which  offers or sales are being made, a  post-effective  amendment to
the Registration  Statement:  (i) to include any prospectus  required by Section
10(a)(3) of the  Securities  Act of 1933;  (ii) to reflect in the prospectus any
facts or events arising after the effective date of the  Registration  Statement
(or the most recent post-effective amendment thereof) which,  individually or in
the aggregate,  represent a fundamental  change in the  information set forth in
the Registration  Statement;  and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in the Registration

                                      -22-

<PAGE>



Statement  or any  material  change  to  the  information  in  the  Registration
Statement, including (but not limited to) any addition or deletion of a managing
underwriter;  (2) that for the purpose of  determining  any liability  under the
Securities Act of 1933,  each  post-effective  amendment shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of  securities at that time shall be deemed to be the initial bona fide
offering   thereof;   and  (3)  to  remove  from  registration  by  means  of  a
post-effective  amendment any of the securities  being  registered  which remain
unsold at the termination of the offering.

     The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  Annual  Report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities  offered  therein,  and the offering of securities at
that time shall be deemed to be the initial bona fide offering thereof.

     The  undersigned  Registrant  hereby  undertakes  to deliver or cause to be
delivered with the prospectus,  to each person to whom the prospectus is sent or
given,  the latest annual  report to security  holders that is  incorporated  by
reference  in  the  prospectus  and  furnished   pursuant  to  and  meeting  the
requirements  of Rule 14a-3 or Rule 14c-3 under the  Securities  Exchange Act of
1934;  and,  where  interim  financial  information  required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus,  to deliver, or
cause to be delivered,  to each person to whom the  prospectus is sent or given,
the latest  quarterly  report that is specifically  incorporated by reference in
the prospectus to provide such interim financial information.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the Registrant's Articles of Incorporation, or otherwise,
the  Registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange Commission indemnification is against public policy as expressed in the
Act  and  is,  therefore,   unenforceable.   In  the  event  that  a  claim  for
indemnification against liabilities (other than the payment by the Registrant of
expenses  incurred or paid by a director,  officer or controlling  person of the
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by a director,  officer or  controlling  person in connection  with the
securities being  registered,  the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court
of appropriate  jurisdiction the question whether such  indemnification by it is
against  public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

Re:      Medical Dynamics, Inc.
         Registration Statement on Form S-3
         Registration No. 333-

Ladies and Gentlemen:

     In  connection  with  the  above-captioned   Registration   Statement  (the
"Registration   Statement")  filed  by  Medical   Dynamics,   Inc.,  a  Colorado
corporation  (the  "Company"),  with  the  Securities  and  Exchange  Commission
pursuant to the  Securities  Act of 1933, as amended (the "Act"),  and the rules
and  regulations  thereunder  as amended  through the date hereof,  we have been
requested to render our opinion as to the legality of the 523,834  shares of the
Company's common stock (the "Securities") included therein.

     In connection  with this opinion,  we have  examined  originals,  or copies
certified or otherwise  identified to our satisfaction,  of (i) the Registration
Statement (including all amendments thereto); (ii) the Articles of Incorporation
and the By-laws of the Company,  each as amended to date;  and (iii)  records of
certain of the  Company's  proceedings  relating  to,  among other  things,  the
issuance  and sale of the  Securities.  In  addition,  we have made  such  other
examinations  of law and  facts as we  considered  necessary  in order to form a
basis for the opinions hereunder expressed.

     In our  examination of the aforesaid  documents,  we have assumed,  without
independent investigation, the genuineness of all signatures, the enforceability
of the  documents  against  each  party  thereto  other  than the  Company,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
the  original  documents  of  all  documents   submitted  to  us  as  certified,
photostatic,  reproduced or conformed copies of validly  existing  agreements or
other  documents,  the  authenticity of all such latter  documents and the legal
capacity of all  individuals  who have  executed  any of the  documents  we have
reviewed.

     In  expressing  the  opinions  set  forth  herein,   we  have  relied  upon
representations  as to factual matters  contained in certificates of officers of
the Company.
