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


                     Up to 1,433,082 Shares of Common Stock
                 Offered for Resale by the Selling Shareholders

     This  Prospectus  relates  to up to  1,433,082  shares of  common  stock of
Medical Dynamics,  Inc., a Colorado  corporation (the "Company" or "MEDY") which
are being  offered  and sold by The Tail Wind Fund,  Inc.  ("Tail  Wind") and by
Merchant Capital, Inc. ("MCI"),  collectively referred to herein as the "Selling
Shareholders."  The shares being offered by this  Prospectus will be received by
the  Selling  Shareholders  are defined in greater  detail in the section  below
entitled "Selling Shareholders," but which are summarized as follows:

     up to 800,000 shares of MEDY's common stock (the "Common  Stock") which are
     issuable to Tail Wind as a result of the  conversion of certain  debentures
     referred to as the "1998  Debentures" in the aggregate  principal amount of
     $1,500,000  based on a conversion price equal to the lesser of the "Ceiling
     Price"  or of the  Market  Price  (both as  defined)  on the  business  day
     immediately preceding the conversion date (the "Conversion Shares");

     up to 311,467 shares of the Common Stock which are issuable to Tail Wind as
     interest  on the 1998  Debentures  to be  calculated  at  Market  Price (as
     defined) (the "Interest Shares");

     up to 150,000  shares  issuable  to Tail Wind on  exercise  of a warrant to
     purchase  Common  Stock  referred  to as the "1998  Warrant" at an exercise
     price equal to $2.58 per share (the "Warrant Shares");

     up to 84,615 shares issuable to Tail Wind on exercise of a warrant referred
     to as the "1997  Warrant"  at an  exercise  price equal to $3.375 per share
     (the "Warrant Shares");


Registration Statement - Medical Dynamics, Inc.                           Page 5

<PAGE>


     up to 12,000 shares of Common Stock held by MCI; and

     up to 75,000  shares of  Common  Stock  issuable  to MCI upon  exercise  of
     options  issued to MCI (the "MCI  Options")  at prices from $4.00 per share
     (as to 25,000 shares), $4.50 per share (25,000 shares), and $5.00 per share
     (25,000 shares).

     For the purposes of the 1998 Debentures  held by Tail Wind,  "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. As of November 2, 1998,
Market Price as defined in the 1998  Debentures  would be $1.875 per share.  For
the purposes of the 1998 Debentures,  "Ceiling Price" is defined to mean 105% of
the average  closing bid price of the Common  Stock for the twenty  trading days
prior to the effective date of this registration statement. The Ceiling Price is
to be adjusted on July 31, 2000, to 105% of the Market Price on that date if the
adjustment  would  result in a lower  price,  but in no event  shall the Ceiling
Price be adjusted to an amount less than $2.25.  The number of shares  available
for  sale  by Tail  Wind  has  been  estimated  because  the  conversion  of the
convertible  securities  will be based in part on the market price of the Common
Stock on the date of conversion.

     The 1998  Debentures held by Tail Wind are currently  convertible,  and the
1997 and the 1998  Warrants  also held by Tail Wind are  currently  exercisable,
subject,  however,  to the "5%  Limitation"  which is  explained  in the section
entitled  "Selling  Shareholders,"  below.  The MCI Options held by MCI are also
currently exercisable.

     MEDY's common stock is traded in the over-the-counter  market and is quoted
on the Nasdaq  SmallCap  Market  under the symbol  "MEDY." On  November 2, 1998,
Nasdaq  reported  that the last sale  price of the  Common  Stock was $2.625 per
share.

     The Company  will not receive any  proceeds  from the sale of the Shares by
either of the Selling Shareholders, but will receive the exercise prices payable
upon exercise of the 1997 Warrants,  the 1998  Warrants,  or the MCI Options (if
exercised  for  cash).  There  can be no  assurance  that all or any part of the
Warrants or the MCI Options will be exercised or that they will be exercised for
cash.  All expenses  incurred in connection  with this offering (not  including,
however, commissions or discounts paid or allowed by the Selling Shareholders to
underwriters, dealers, brokers or agents) are being borne by the Company.

     The Selling Shareholders have not advised the Company of any specific plans
for the distribution of the Shares, but it is anticipated that the Shares may be
sold from time to time in transactions (which may include block transactions) on
the Nasdaq  SmallCap market at the market prices then  prevailing.  Sales of the
Shares  also may be made  through  negotiated  transactions  or  otherwise.  The
Selling  Shareholders  and the brokers and dealers though which the sales of the
Shares may be made may be deemed to be "underwriters" within the meaning set

The Company


Registration Statement - Medical Dynamics, Inc.                           Page 9

<PAGE>


     Medical Dynamics,  Inc., a Colorado corporation  incorporated in March 1971
("MEDY" or the "Company"),  is engaged in the design,  development,  manufacture
and  marketing  of medical  and dental  video  cameras  and  related  disposable
products for a variety of professional  specialties.  MEDY's principal  products
are small,  color,  medical and dental video  camera  systems for use in patient
diagnosis and various  surgical  procedures.  MEDY has been  manufacturing  such
cameras since August 1981.  In October 1997 MEDY acquired  Computer Age Dentist,
Inc. (CADI), a California  corporation  based in Los Angeles,  California.  CADI
operates as a  wholly-owned  subsidiary of the Company which  develops and sells
practice  management  software  and  related  electronic  services to the dental
profession.  In February  1998,  through CADI the Company  acquired  Information
Presentation  Systems,  Inc. of Marietta,  Georgia,  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.

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

The Securities

     Currently  the only class of securities of MEDY for which there is a public
market is its Common  Stock.  As of September  30, 1998,  there were  10,034,500
shares  of  its  Common  Stock  outstanding.  See  "Description  of  Securities"
commencing on page 22, of this Prospectus.


The Offering

     The Selling  Shareholders  are  offering up to  1,433,082  shares of Common
Stock (the "Shares"). Of these:

     1,346,082  shares  will be received  by the Tail Wind upon  conversion  and
     exercise of convertible  securities  described in "The 1997  Debentures and
     the 1997 Warrants" and "The 1998  Debentures  and the 1998 Warrants"  under
     the caption "Selling Shareholders" beginning on page 17 of this Prospectus.
     The number of shares available for sale by the Tail Wind has been estimated
     because the conversion of the convertible  securities will be based in part
     on the market price of the Common Stock on the date of conversion.

     12,000 shares are held by MCI, and an additional 75,000 shares are issuable
     upon  exercise of the MCI  Options  described  under the  caption  "Selling
     Shareholders" beginning on page 17 of this Prospectus.



Registration Statement - Medical Dynamics, Inc.                          Page 10

<PAGE>


The Selling Shareholder will receive all of the proceeds from the offer and sale
of the Shares.  The Company  will receive  proceeds to the extent  either of the
Selling Shareholders exercise the Warrants or the MCI Options for cash.

     The Company  will pay the costs  related to the filing of the  registration
statement in which this Prospectus is included.  The Selling  Shareholders  will
pay their own  expenses  related to the offer and sale of the Shares,  including
any underwriter discounts or commissions.


                                  RISK FACTORS

     The securities  offered hereby are speculative and involve a high degree of
risk,  including,  but not limited to, the risk factors  described  below.  Each
prospective  investor  should  carefully  consider  the  following  risk factors
inherent in and affecting  the business of MEDY and this offering  before making
an investment decision.

     1.  Losses from  Operations.  MEDY has a history of net  operating  losses,
which, when accumulated,  total $19,793,000 through September 30, 1998. This has
resulted  in  working  capital  shortages  from  time to time.  MEDY can give no
assurance  that  it  will  be able to  operate  profitably  in the  future.  The
independent  auditor's report on the Company's financial statements for the year
ended September 30, 1998, contains an explanatory  paragraph as to the Company's
ability to continue as a going  concern.  The  likelihood of the success of MEDY
must  be  considered  in  light  of  the   problems,   expenses,   difficulties,
complications  and  delays   frequently   encountered  in  connection  with  the
regulatory environments in which MEDY operates, the problems related to research
and development of new products subject to Food and Drug Administration  ("FDA")
and other government approvals and regulations, and substantial competition from
other companies as to those products.

     2. Working Capital  Shortages and Dependence on Third Party  Financing.  As
discussed  in MEDY's  Annual  Report on Form  10-KSB for the  fiscal  year ended
September 30, 1998, MEDY has regularly  incurred  working capital  shortages and
has sought to  alleviate  these  shortages  through  debt and  equity  financing
provided by third party and affiliated  investors and, most recently,  through a
working  capital  line of  credit  from an  unaffiliated  bank.  There can be no
assurance  that such sources of capital  will  continue to be available on terms
which are  acceptable to MEDY.  Eventually  MEDY will be required to finance its
operations  with its cash flow,  and MEDY is attempting to increase its revenues
in an effort to do so.  There can be no  assurance,  however,  that the  working
capital  shortages  which  MEDY  has  incurred  will  not  continue  and may not
adversely  affect MEDY's ability to raise  additional  debt or equity capital if
necessary.

     3. Risk of Dilution from  Conversion of  Convertible  Debentures.  Assuming
full conversion of the 1998 Debentures as of the date hereof at the Market Price
set forth on the cover page of this  prospectus,  800,000 shares of Common Stock
would be issued to the Selling Shareholder. This would represent approximately



Registration Statement - Medical Dynamics, Inc.                          Page 11

<PAGE>


8% of the Common  Stock which  would then be  outstanding.  Although  this would
result in a conversion of a liability on MEDY's  balance  sheet to equity,  this
would result in dilution to existing  MEDY  shareholders,  many of whom may have
purchased Common Stock in the over-the-counter market at a higher price than the
price at which Tail Wind would convert its Debentures. MEDY has the right to pay
interest  on the 1998  Debentures  in cash or shares  of Common  Stock at Market
Price, in its discretion. To date MEDY has paid interest in shares of its Common
Stock and intends to continue to do so in the future to conserve  MEDY's working
capital.  It appears to MEDY that Tail Wind has sold the shares  underlying  the
1997 Debentures and the Interest  Shares  pursuant to the existing  registration
statement shortly after converting the 1997 Debentures or receiving the Interest
Shares.

     It can be  expected  that the sales of the Common  Stock by Tail Wind,  and
perhaps even the  possibility of these sales,  have had and may continue to have
in the future a negative impact on the market for the Common Stock. In addition,
for so long as the 1998  Debentures  remain  outstanding,  the conversion  ratio
(which is based on the lowest  prices over a sixty day  period) may  continue to
exert a downward pressure on the market price for the Common Stock.

     4. Product Liability. MEDY could be subject to claims for personal injuries
resulting from the use of its products.  Although MEDY carries product liability
insurance  coverage in amounts it believes to be commercially  reasonable within
its  industry,  there can be no assurance  that the amount of coverage  would be
sufficient  to cover any proven  claims.  Claims  proven and damages  awarded in
excess of the coverage limits would have a material adverse effect on MEDY.

     5.  Acquisition of New  Businesses.  During the fiscal year ended September
30, 1998, MEDY has acquired three new businesses.  The Company is in the process
of integrating its accounting,  financial  management,  personnel,  and business
functions with those of its new businesses.  There can be no assurance that MEDY
will be able to do so  successfully,  or that it will be able to do so on a cost
effective  basis.  Based on the  experience  of more  than one  year  since  the
acquisition of CADI,  and more than six months since the  acquisition of IPS and
CDS, MEDY does not foresee any  difficulties  in completing  the  integration of
these new businesses.

     6. Need for Additional Financing and Risk of Dilution.  The Company has not
generated  earnings in the past several years and there can be no assurance that
MEDY will be able to do so in the future.  Although management believes that the
capital available to MEDY is sufficient to fund its short-term operations, it is
unable to  predict  what  additional  expenses  will be  incurred  beyond  those
contemplated  since research,  development,  and marketing  programs  frequently
involve unanticipated expenditures.  To the extent additional capital is needed,
MEDY  may  seek  financing  through  additional  offerings  of  equity  or  debt
securities.  Sales of additional  equity  securities  could dilute the ownership
interest of existing shareholders, including investors in this Offering. Sales



Registration Statement - Medical Dynamics, Inc.                          Page 12

<PAGE>


of debt securities would  necessarily  result in interest expense and would risk
the loss of the  Company's  assets  if MEDY  were to  become  unable  to pay the
interest.  Offerings of debt securities also could include  conversion  features
requiring  the  issuance  of  additional  debt  or  equity   securities   which,
ultimately,  also could dilute the  ownership of prior  shareholders,  including
purchasers  of the shares  being  offered by the  Selling  Shareholders  in this
Offering.

     7.  Limitations on Ability to Obtain  Additional  Financing.  The agreement
between  MEDY and Tail Wind  contains  limitations  on MEDY's  ability  to raise
additional  capital by issuing  convertible debt or equity  securities at prices
which  fluctuate or pursuant to a  registration  statement for selling  security
holders other than the Selling Shareholder. Although these restrictions prohibit
the  Company  from  raising  working  capital or other  equity  investment  in a
transaction  similar to the transactions  with the Selling  Shareholder until at
least  August  1999,  the Company  believes  that it will be able to work within
these restrictions to the extent it needs additional  capital. As announced in a
Form 8-K  reporting an event of October 9, 1998,  the Company has entered into a
line of credit  with an  unaffiliated  bank  which  does not  conflict  with the
capital raising limitations contained in the agreement with Tail Wind.

     8. Technological Change and Risk of Technological Obsolescence. The medical
products  segment and the dental products  segment,  the Company's two principal
lines of business,  are subject to rapid and significant  technological  change.
Accordingly,  MEDY's  viability  will be  dependent  on its ability to introduce
competitive  products  to the  marketplace  in a timely  manner and  enhance and
improve such products to its customers' satisfaction.  There can be no assurance
that MEDY will be able to keep pace with technological  developments or that its
products will not become obsolete.

     9.  Competition -- MEDY and CADI.  MEDY's  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 are  currently  manufactured  and sold by MEDY, or which MEDY may
develop in the future. Some competitors are affiliated with large companies with
substantial economic and personnel resources which greatly exceed those of MEDY.
There can be no assurance  that MEDY will be able to compete  successfully  with
other companies.

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

     10. Potential Conflicts of Interest.  There have been significant conflicts
of interest in the operation and  management of MEDY,  including the purchase by
MEDY of certain equipment and patents from its directors and executive officers,



Registration Statement - Medical Dynamics, Inc.                          Page 13

<PAGE>


granting of royalties,  loans made  available to MEDY through its Chairman,  and
the employment by MEDY of sons of two of MEDY's  directors.  These  transactions
were not  negotiated at arms' length,  although the Board of Directors  believes
that all of these  transactions  were fair to and in the best interests of MEDY.
Although  MEDY uses its best  efforts to minimize  conflicts  of  interest,  the
existence of such conflicts may impact MEDY in its business activities.

     11. Dependence on Management.  At present, the success of MEDY is dependent
upon the active  participation of its management,  MEDY's Chairman and principal
shareholder,  Dr.  Adair,  and its Chief  Executive  Officer,  Van Horsley,  Dr.
Adair's step-son. CADI's operations are significantly dependent on the continued
availability  of the services of Daniel L. Richmond and Chae U. Kim. The loss of
the services of any of these persons would have a material adverse effect on the
Company.  In the event of such a loss,  MEDY can give no assurance that it could
replace any person without incurring  substantial  additional expense. MEDY does
not have employment contracts with either Mr. Horsley or Dr. Adair. Both Messrs.
Richmond and Kim are subject to five year employment  agreements which expire in
October 2002.

     12.  Government  Regulation.  Because  certain  of the  products  that MEDY
manufactures  are used in surgery and other medical  applications,  the products
are  subject to  regulations  of and close  scrutiny  by agencies of the federal
government, including the FDA. Although MEDY believes that its facilities are in
compliance with all applicable  regulations,  MEDY can give no assurance that it
will be able to comply fully with all of the government  regulations to which it
is 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 MEDY's
manufacturing  business  which  would  have a material  adverse  effect on MEDY.
Although MEDY has had  difficulty in certain  instances in the past in obtaining
FDA  approval  on new  products,  MEDY's  current  business  in  not  materially
dependent on this issue and,  therefore,  this is not deemed to be a significant
risk.

     13. Protection of Technology. Although MEDY obtains secrecy agreements from
its employees and others having access to its trade secrets and holds patents on
certain of its  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 MEDY's  patents or divulge  its trade  secrets can be
expensive and time consuming.  The  unauthorized use of MEDY's trade secrets and
the infringement of its patents could have a material adverse effect on MEDY and
its ability to compete.

     14.  Significant  Investment  in  Intangible  Assets.  As a  result  of the
acquisitions  of  CADI,  IPS and  CDS,  MEDY  has a  significant  investment  in
intangible assets, amounting to approximately $6,089,000 (66% of MEDY's total




Registration Statement - Medical Dynamics, Inc.                          Page 14

<PAGE>


assets).  The expenses associated with the annual amortization of the intangible
assets  will make it more  difficult  for MEDY to realize  net  income.  Because
intangible  assets are incapable of precise  valuation,  it may be necessary for
MEDY to reduce the balance sheet  valuation of these assets at some later point,
although MEDY has no intention or basis to do so at the present time.

     15. Limited Public Market; Price Volatility; and No Assurance of Liquidity.
There currently is a limited public market for MEDY's Common Stock. No assurance
can be given that a market for the Common Stock will continue subsequent to this
offering  or that  purchasers  will be able to resell  their  securities  at the
purchase  prices paid in this Offering,  or liquidate their  investment  without
considerable  delay,  if at all.  If a market  does  continue,  the price may be
highly volatile.  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. Further, most lending institutions will not permit the
use of low-priced or thinly traded securities as collateral for loans.

     16. Dependence on Principal Customers. In the past, MEDY has been dependent
on a limited number of principal customers.  During the 1997 fiscal year, MEDY's
principal  customer which  accounted for 61% of MEDY's  revenues was Information
Presentation  Systems,  Inc., of Marietta,  Georgia.  IPS  purchased  certain of
MEDY's  camera  products  and  packaged  the  products  with other  hardware and
software,  including CADI's software, for resale. As described elsewhere in this
Prospectus, MEDY, though CADI, acquired IPS in February 1998. (See MEDY's Annual
Report on Form  10-KSB for the fiscal year ended  September  30,  1998,  "Item 1
Business"  and Item 6 -  "Management's  Discussion  and  Analysis  of  Financial
Condition and Results of Operations"  therein) which report is  incorporated  by
reference).  As a result of the IPS acquisition during the 1998 fiscal year, the
Company  did not have any single  customer  accounting  for more than 10% of its
sales during the 1998 fiscal year. It is possible that there may be  significant
customers in future fiscal years.

     17. No Dividends Paid or Contemplated.  No dividends have been paid by MEDY
in the  past and  dividends  are not  contemplated  in the  foreseeable  future.
Investors who anticipate the need of either immediate or future income by way of
dividends  from their  investment  should  refrain  from the  purchase of Shares
offered hereby. The Company's lending arrangements with Norwest Business Credit,
Inc., significantly restrict the Company's ability to pay dividends.

     18. Year 2000 Compliance. Although there can be no assurance, MEDY does not
anticipate that it 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.  None of the  information  technology  or other
software and hardware systems utilized by MEDY and its subsidiaries incorporates
technology  that is incapable  of  recognizing  dates beyond  December 31, 1999.
CADI, through its internal staff, has developed its dental practice management


Registration Statement - Medical Dynamics, Inc.                          Page 15

<PAGE>


software for the Windows platform and,  consequently,  such software  recognizes
dates beyond  December 31, 1999.  While CADI is still  supporting  some software
which is DOS-based or otherwise may not be Y2K  compliant,  the customers  using
this software  have been advised of their need to upgrade their office  software
in  anticipation  of Y2K.  Even if MEDY or CADI were to  provide  the  necessary
software  upgrade to these  customers  at no cost  (which  CADI does not have an
obligation to do), the total loss to MEDY would be less than $60,000 in revenues
and is not considered to be material.  Because CADI's dental practice management
software  is Y2K  compliant,  CADI and MEDY  believe  that  this  offers  them a
marketing  opportunity  in that some of their  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.  There can be no assurance,
however, that these offices will all purchase dental practice management systems
from CADI.

     In making the foregoing determination, MEDY and CADI have assessed embedded
systems   contained   in  their   office   buildings,   equipment,   and   other
infrastructures.  As a result,  MEDY and CADI have not established a contingency
plan to come into effect in the event of a Y2K catastrophe,  and management does
not believe  that such a plan is  necessary.  Of course,  MEDY and CADI are both
dependent on  facilities  outside of their  control,  such as  electrical  power
supplies, banking facilities,  transportation facilities (such as airlines), and
communications facilities.  While MEDY and CADI believe, based on public reports
and some notifications they have received,  that these outside facilities are or
will be Y2K compliant, neither MEDY nor CADI has any other basis for determining
their  compliance.  The operations of MEDY and CADI would be  significantly  and
adversely  affected if any of these outside facilities are adversely affected by
the millenium change or by other issues related to Y2K.



                                 USE OF PROCEEDS

     The Selling  Shareholder  will  receive all  proceeds  from the sale of the
Shares offered and sold under this Prospectus.

     If, and to the  extent,  the 1997 and 1998  Warrants or the MCI Options are
exercised  for cash,  the Company will receive  proceeds  equal to the aggregate
exercise price of the Warrants and Options, approximately $672,600 if all of the
1997 and 1998  Warrants and $637,500 if all of the MCI Options are exercised for
cash.  The 1997 and 1998 Warrants (but not the MCI Options)  allow the holder to
effect a "cashless"  exercise of the Warrants.  The Warrants and MCI Options are
described  under the captions  "The 1997  Warrants,"  "The 1998  Debentures  and
Warrants" and "The MCI Options" in this Prospectus under "Selling Shareholders."
Any  proceeds  the Company  receives  from the  exercise of the Warrants and MCI
Options will be used for working  capital.  There can be no  assurance  that any
Warrants or MCI Options will ever be exercised.


                                   THE COMPANY


Registration Statement - Medical Dynamics, Inc.                          Page 16

<PAGE>


     Medical Dynamics,  Inc., a Colorado corporation  incorporated in March 1971
(referred  to herein as "MEDY" or the  "Company"),  is  engaged  in the  design,
development,  manufacture  and marketing of medical and dental video cameras and
related disposable  products for a variety of professional  specialties.  MEDY's
principal products are small, color, medical and dental video camera systems for
use in  patient  diagnosis  and  various  surgical  procedures.  MEDY  has  been
manufacturing such cameras since August of 1981.

     In October 1997 MEDY  acquired  100% of the  outstanding  capital  stock of
Computer  Age  Dentist,  Inc.  (CADI),  a  California  corporation  based in Los
Angeles,  California.  CADI is engaged in the  development  and sale of Practice
Management Software and related electronic services to the dental profession.

     In February 1998 CADI acquired by merger Information  Presentation Systems,
Inc. of Marietta,  Georgia ("IPS"), a supplier of customized  multimedia systems
for use in a variety of dental operatory environments.

     In April 1998, CADI acquired by merger Command Dental Systems of Farmington
Hills,  Michigan  ("Command"),  which  develops  and markets  turn-key  computer
systems for the efficient management of dental practices.

In  reviewing  MEDY's  financial  statements  which are  incorporated  herein by
reference,  it should  be noted  that a  substantial  portion  of the  Company's
revenues  for fiscal 1998 derives  from the  businesses  acquired by MEDY during
fiscal  1998 and not from  MEDY's  historical  businesses  of medical and dental
camera  manufacturing.  For example,  MEDY's  revenues  during  fiscal year 1998
(ending September 30, 1998) totaled  approximately  $7,847,000;  of that amount,
approximately  $7,575,000 was  attributable to the acquisitions of CADI, IPS and
Command.

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

     services  pursuant to a  Financial  Public  Relations/Consulting  Agreement
     (12,000  shares),  and are issuable upon exercise of options  issued to MCI
     pursuant to that agreement (75,000 shares underlying the MCI Options).

Neither  Tail Wind nor MCI owns,  directly or  indirectly,  any other  shares of
Common  Stock.  Assuming that Tail Wind and MCI sell all Shares  offered  hereby
(although there is no requirement that either do so), they will beneficially own
no shares of Common Stock at the conclusion of the Offering.


Tail Wind

     General.  The exact number of shares to be offered and sold by Tail Wind is
not known at the date of this  Prospectus  because  Tail Wind will  acquire  the
shares upon  conversion of  convertible  securities at varying  prices,  most of
which will be  converted  based on the market  price of the Common  Stock on the
date of  conversion.  Were the 1998  Debentures  converted in full at the Market
Price  set  forth on the  cover  page of this  Prospectus  and the 1997 and 1998
Warrants exercised in full, the following number of shares of Common Stock would
be issued:

1997                    Warrants  84,615  shares  of Common  Stock,  exercisable
                        through October 31, 2000 at a price of $3.375 per share

1998 Debentures         800,000 shares

1998                    Warrants  150,000  shares of Common  Stock,  exercisable
                        through July 31, 2003 at a price of $2.58 per share

Tail Wind has agreed by contract  that it will at no time own more than 4.99% of
the  Common  Stock.  This  contractual   limitation  prohibits  Tail  Wind  from
converting  the 1998  Debentures or exercising  the 1997 or 1998 Warrants to the
extent that  conversion  or exercise  would result in Tail Wind owning more than
4.99% of the issued and outstanding  shares of Common Stock.  This limitation is
referred to in this  Prospectus  as the "5%  Limitation."  As a result of the 5%
Limitation  and  pursuant  to SEC Rule 13d- 4, Tail  Wind  disclaims  beneficial
ownership  of all  shares  to the  extent  such  ownership  would  result  in it
exceeding  the 5%  Limitation.  Since  the 5%  Limitation  is  the  result  of a
contractual  agreement  between  MEDY and  Tail  Wind,  the  parties  could,  by
agreement,  waive the restriction.  If all the Shares being offered by Tail Wind
are sold,  Tail Wind will own no shares of the Company's  common stock following
the completion of the Offering.

     The 1997  Warrants.  On October 31, 1997, in a private  placement  offering
under  Regulation D, Tail Wind  purchased  debentures in an aggregate  principal
amount of $1,100,000  (the "1997  Debentures").  All of the 1997 Debentures have
been  converted  as of the date  hereof  into a total of 520,349  shares of MEDY
Common Stock, and the underlying shares have been sold.

     In connection with Tail Wind's purchase of the 1997 Debentures, the Company
issued to Tail Wind  warrants to purchase up to 84,615  shares of Common  Stock,
exercisable  through  October 31, 2000 at a price of $3.375 per share (the "1997
Warrants").  The 1997 Warrants contains standard anti-dilution provisions should
MEDY issue stock dividends or conduct a stock split or  reorganization,  or upon
occurrence  of certain  other  events.  Subject to the 5%  Limitation,  the 1997
Warrants are currently exercisable.

     The 1998 Debentures and Warrants.  On July 31, 1998, in a private placement
offering under Regulation D, the Selling Shareholder  purchased debentures in an
aggregate  principal  amount of $1,100,000  and, in November 1998,  purchased an
additional  $400,000  principal  amount  (the  "1998   Debentures").   The  1998
Debentures bear interest at 8% per annum, with interest payable semi-annually on
January 5 and July 5 of each year,  commencing  January 5, 1999.  Principal  and
accrued but unpaid  interest is due in full on July 31, 2003.  Events of default
under the 1998  Debentures  which could result in  acceleration  of amounts due,
among other  things,  include:  (i) failure to pay any amounts of  principal  or
interest  when due;  (ii) failure of the Common Stock to be listed on the Nasdaq
SmallCap Market, the Nasdaq National Market, the New York Stock Exchange, or the
American Stock Exchange; and/or (iii) events of bankruptcy and similar events.

     The Company may, at its option, pay accrued interest on the 1998 Debentures
with  shares of its Common  Stock  valued at Market  Price.  Based on the Market
Price set forth on the  cover  page of this  Prospectus,  assuming  all  accrued
interest on the 1998  Debentures  is paid in shares of Common Stock and that the
1998  Debentures  are  held  to  maturity,   the  Company  will  pay  Tail  Wind
approximately 311,467 shares of Common Stock (the "1998 Interest Shares").

   
     Tail Wind is entitled to convert the 1998 Debentures,  in whole or in part,
into  shares of Common  Stock at the  lesser  of  Market  Price or the  "Ceiling
Price".  As of  January  31,  1999,  1998  Debentures  totaling  $1,233,333  are
convertible  or will be  convertible  within sixty days; an additional  $133,334
will be convertible  after May 14, 1999, and all of the 1998  Debentures will be
convertible  after July 12, 1999. For purposes of the 1998 Debentures,  "Ceiling
Price"  means 105% of the average  closing bid price of the Common Stock for the
20 trading days  immediately  preceding the effective date of this  registration
statement.  If conversion  has not occurred by July 31, 2000,  the Ceiling Price
thereafter will mean 105% of the Market Price on July 31, 2000 if the adjustment
would  result  in a lower  price,  except  that the  Ceiling  Price  will not be
adjusted  below  $2.25 per  share.  Assuming  that  Tail Wind can and  elects to
convert the full amount of     


Registration Statement - Medical Dynamics, Inc.                          Page 19

<PAGE>


the 1998 Debentures  into shares of Common Stock,  based on the Market Price set
forth on the cover  page of this  Prospectus,  Tail Wind would  receive  800,000
shares of Common Stock (the "1998 Conversion Shares").

     In connection  with Tail Wind's purchase of the 1998 Debentures in July and
November  1998,  the  Company  issued to Tail Wind  warrants to purchase up to a
total of 150,000 shares of Common Stock,  exercisable through July 31, 2003 at a
price of $2.58 per share  (the  "1998  Warrants").  The 1998  Warrants  contains
anti-dilution  provisions  should MEDY issue stock  dividends or conduct a stock
split or reorganization,  or upon occurrence of certain other events. Subject to
the 5% Limitation, the 1998 Warrants are currently exercisable.

     If MEDY is  unable to meet the  effectiveness  requirement  for the  shares
underlying the 1998  Debentures  and Warrants,  maintain  effectiveness  of this
registration  statement,  or  maintain  the  listing of the Common  Stock on the
Nasdaq  SmallCap  or the NMS  Market (or senior  stock  exchange),  MEDY will be
required  to pay  liquidated  damages to the Selling  Shareholders  in an amount
equal to 2% of the aggregate  principal  amount of the 1998  Debentures for each
month or portion thereof following the required  effectiveness date during which
the registration statement is not effective.  In such event, MEDY shall bear all
reasonable  fees or costs incurred by Tail Wind for legal counsel as a result of
the filing of any post-effective  amendments to the Registration Statement.  The
amounts  payable as  liquidated  damages  pursuant  to this  paragraph  shall be
payable  in  cash  (not  Common  Stock).  Because  MEDY  was  unable  to  obtain
effectiveness of the registration  statement within the time limits  established
by contract,  MEDY may be liable for up to $22,000 as a penalty through December
31, 1998.  Additional  amounts may continue to accrue at the rate of $22,000 per
month until this registration statement becomes effective. After March 16, 1999,
the contractual penalty will increase to $30,000 per month.

     The registration  rights agreement contains standard  cross-indemnification
provisions  and  requirements  for  contribution   should  the   indemnification
provisions be found to be unavailable.

Merchant Capital

     On   September   1,  1998,   MEDY   entered   into  a   "financial   public
relations/consulting   agreement"  with  Merchant  Capital,  Inc.  ("MCI").  MCI
warranted  to MEDY  that it is  "experienced  in the field of  financial  public
relationships  and in complying with the  requirements of federal and applicable
state  securities laws with respect to [its]  activities in the financial public
relations  field."  MEDY  appointed  MCI  as a  non-exclusive  financial  public
relations  counsel to assist  MEDY in dealing  with the  investment  banking and
broker-dealer communities,  and in organizing,  writing, and distributing public
relations   communications.   The   Agreement   with  MCI   contained   standard
indemnification provisions.



Registration Statement - Medical Dynamics, Inc.                          Page 20

<PAGE>


     The Agreement with MCI does not require that MEDY pay any cash compensation
to MCI; the Agreement  required that MEDY pay MCI shares of Common Stock and MCI
Options. MEDY terminated the Agreement with MCI on December 28, 1998. MCI earned
and has been  paid  12,000  shares  of MEDY's  restricted  Common  Stock and MCI
Options to acquire 75,000 shares of Common Stock as follows:

                  25,000  exercisable at $4.00 per share;  25,000 exercisable at
                  $4.50 per share; and 25,000 exercisable at $5.00 per share.

In all cases,  the MCI  Options are  exercisable  for cash,  and expire  (unless
previously exercised) at the close of business on August 31, 2000.


                              PLAN OF DISTRIBUTION

     The Selling Shareholders have advised MEDY that they may sell the Shares in
one or more transactions  (which may involve one or more block  transactions) on
the  over-the-counter  markets on Nasdaq and upon  terms then  prevailing  or at
prices  related to the then current  market price,  or in separately  negotiated
transactions or in a combination of such transactions. The Shares offered hereby
may be sold by one or more of the following methods,  without limitation:  (a) a
block  trade in which a broker or dealer so  engaged  will  attempt  to sell the
shares as agent but may  position and resell a portion of the block as principal
to facilitate the transaction;  (b) purchases by a broker or dealer as principal
and resale by such broker or dealer for its account pursuant to this Prospectus;
(c)  ordinary  brokerage  transactions  and  transactions  in which  the  broker
solicits purchasers; (d) privately negotiated transactions; and (e) face-to-face
transactions between sellers and purchasers without a broker-dealer.

     The Selling  Shareholders  may also sell Shares in accordance with Rule 144
under the Securities Act of 1933, as amended, if Rule 144 is then available. The
Selling  Shareholders  may be deemed to be an  underwriter of the Shares offered
hereby within the meaning of the Securities Act of 1933, as amended.

     In effecting sales,  brokers or dealers engaged by the Selling Shareholders
(or either of them) may  arrange  for other  brokers or dealers to  participate.
Such broker or dealers may receive  commissions  or  discounts  from the Selling
Shareholders  in amounts  to be  negotiated  by the  Selling  Shareholders.  The
Selling Shareholders may enter into hedging transactions with broker-dealers and
the  broker-dealers  may engage in short sales of the Common Stock in the course
of hedging the positions they assume with the Selling  Shareholders  (including,
without  limitation,  in connection with the distribution of the Common Stock by
such broker-dealers).  The Selling Shareholder may also engage in short sales of
the  Common  Stock  and  may  enter  into  option  or  other  transactions  with
broker-dealers   that   involve  the   delivery  of  the  Common  Stock  to  the
broker-dealers, who may then resell or otherwise transfer such Common Stock.



Registration Statement - Medical Dynamics, Inc.                          Page 21

<PAGE>


Such  broker-dealers  and  any  other   participating   broker-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  broker-dealers  may  be  deemed  to  be  underwriting  discounts  and
commissions under the Securities Act of 1933, as amended.

     In  order  to  comply  with  the  securities  laws of  certain  states,  if
applicable,  the  Shares  will  be  sold  in  such  jurisdictions  only  through
registered or licensed broke-dealers.

     MEDY  will  pay  all  of  the  expenses  incident  to the  filing  of  this
Registration  Statement,  estimated to be $45,000.  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.  The Selling  Shareholder 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. MEDY has agreed
to use its best efforts to keep the  registration  of the Shares  offered hereby
effective  until the date upon  which all of the Shares  offered by the  Selling
Shareholders have been sold.

                            DESCRIPTION OF SECURITIES

Common Stock

     Authorized. MEDY is authorized to issue 30,000,000 shares of $.01 par value
common stock (the "Common  Stock").  No holder of any shares of Common Stock has
any preemptive right to subscribe to any of MEDY's securities. Upon dissolution,
liquidation  or winding up of MEDY,  the  assets  will be divided  pro rata on a
share-for-share  basis among holders of the shares of Common Stock and Preferred
Stock if any shares are outstanding.  All shares of Common Stock outstanding are
fully paid and nonassessable and, when issued, the shares offered hereby will be
fully paid and nonassessable.

     Issued  and  Outstanding.  On  December  31,  1998,  MEDY  had  issued  and
outstanding  10,301,667 shares of Common Stock. This number does not include any
of the estimated 1,433,082 shares issuable upon exercise of the 1998 Debentures,
the 1998  Interest  Shares,  the 1997 and 1998  Warrant  Shares,  or the  shares
underlying the MCI Options which,  if and when issued,  will be offered for sale
pursuant to this Prospectus by the Selling  Shareholders.  For information about
these  shares,  see  the  description   contained  under  the  caption  "Selling
Shareholders" above.

     Dividends.  Holders of Common Stock are entitled to dividends  when, as and
if declared by the Board of Directors out of funds legally  available  therefor,


Registration Statement - Medical Dynamics, Inc.                          Page 22

<PAGE>


subject to the rights, if any, of holders of any outstanding shares of Preferred
Stock.  MEDY has not declared or paid any dividends on its Common Stock and does
not  anticipate  the  declaration  or payment of  dividends  in the  foreseeable
future.

     MEDY's  agreement  with Norwest  Business  Credit,  Inc.  (entered  into in
October  1998 for a  $1,000,000  line of credit  described in more detail in the
Company's  Current  Report on Form 8-K reporting an event of October 9, 1998 and
its Form  10-KSB  for the  year  ended  September  30,  1998,  which  report  is
incorporated by reference herein.

     No Cumulative  Voting.  Each holder of Common Stock is entitled to one vote
per share with  respect to all matters  that are required by law to be submitted
to stockholders.  The stockholders are not entitled to cumulative  voting in 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.

     No  Preemptive  Rights.  Holders  of  Common  Stock  are  not  entitled  to
preemptive rights to purchase additional shares of Common Stock when offered for
sale by the Company.

Preferred Stock

     MEDY is  authorized  to issue up to  5,000,000  shares  of $.001  par value
Preferred  Stock,  in series to be  designated  by the Board of  Directors  (the
"Preferred  Stock"). No shares of Preferred Stock have been issued and it is not
contemplated  that any shares of  Preferred  Stock will be issued by MEDY in the
immediate  future;  however,  the Board may use its  ability to issue  Preferred
Stock to effect the business purposes of MEDY.

     Material  provisions  concerning the terms of any series of Preferred Stock
such as dividend rate, conversion features and voting rights, will be determined
by the Board of Directors of MEDY at the time of such  issuance.  The ability of
the  Board to issue  Preferred  Stock  also  could be used by MEDY as a means of
resisting a change of control of MEDY and,  therefore,  could be  considered  an
"anti-takeover" device.

1997 and 1998 Debentures and Warrants

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.

                           Total                      $45,000


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 such status.  Such 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


Registration Statement - Medical Dynamics, Inc.                          Page 26

<PAGE>


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 he
as a party, is entitled to receive  indemnification 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 such  limitations  as may be imposed on general  public
policy grounds.

     In addition to the foregoing,  unless hereafter limited by the Registrant's
articles of incorporation, a court, upon petition by an officer or director, may
order the Registrant to indemnify such officer or director  against  liabilities
arising in connection with any  proceeding.  A court may order the Registrant to
provide such indemnification,  whether or not the applicable standard of conduct
described   above  was  met  by  the   officer  or   director.   To  order  such
indemnification  the court  must  determine  that the  petitioner  is fairly and
reasonably entitled to such 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.

     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 such 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.  Such 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 such  indemnification.  The person seeking such expense  advances must
also provide the Registrant  with a written  agreement to repay such 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  such  provisions  are  consistent  with the
Colorado  statutes and any  limitations  upon  indemnification  set forth in the
Articles of Incorporation.

     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.  Such policies may
provide for indemnification  whether or not the corporation would otherwise have
the power to  provide  for it. No such  policies  providing  protection  against
liabilities  imposed  under  the  securities  laws  have  been  obtained  by the
Registrant.  The registration rights agreements dated July 31, 1998, and October
31,  1997   between  the   Registrant   and  Tail  Wind.,   provides  for  cross
indemnification  by the  Registrant  and Tail Wind,  in  certain  circumstances,
including for 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
Statement  or any  material  change  to  such  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 such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona

<PAGE>


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 such 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 such  indemnification is against public policy as expressed
in the Act and is,  therefore,  unenforceable.  In the  event  that a claim  for
indemnification  against  such  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 such  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.
