Dear Shareholder:
 
    You  are cordially  invited to attend  a Special Meeting  of Shareholders of
Dimensional Medicine, Inc. (the "Company"), which will be held on April 29, 1996
at 9:00 a.m., Minneapolis Time, at the offices of the Company at 10901 Bren Road
East, Minnetonka, Minnesota.
 
    The purpose of the Special Meeting is to consider and vote upon approval  of
a  Merger Agreement, dated as  of February 5, 1996  (the "Merger Agreement"), by
and among  the  Company,  Dynamic Healthcare  Technologies,  Inc.  ("DHT"),  DMI
Acquisition  Corp.,  a wholly  owned subsidiary  of  DHT ("Newco")  and National
Computer Systems, Inc., the Company's principal shareholder ("NCS"), pursuant to
which the Company  will be merged  with and  into Newco (the  "Merger"). If  the
Merger  is approved and is consummated, the  Company will cease to exist and the
holders of the  Company's common stock  will receive an  aggregate $550,000,  of
which  NCS, the holder of approximately  85% of the Company's outstanding common
stock, will be entitled to receive  $355,000 or approximately $.013 in  exchange
for  each share of the Company's common  stock, and the remaining holders of the
Company's common stock  (the "Minority  Shareholders") will  become entitled  to
receive  in exchange  for each share  of Company  common stock they  hold a cash
payment of $.040, or approximately $195,000 in the aggregate.
 
    Enclosed is  a  Proxy Statement  which  describes the  proposed  Merger  and
contains  financial and other information relating  to the Merger. You are urged
to read the Proxy Statement carefully.
 
    The Board of Directors of  the Company has concluded  that the Merger is  in
the best interests of the Company's shareholders and unanimously recommends that
you  vote FOR  the proposed  Merger. NCS,  which owns  approximately 85%  of the
outstanding shares of  the common  stock of the  Company, has,  pursuant to  the
Merger  Agreement, agreed to vote all shares of  such common stock held by it in
favor of the approval of the Merger (unless such vote would cause NCS to  breach
its fiduciary duties under applicable law). NCS has indicated it intends to vote
in favor of the Merger, and, if NCS votes in such manner, approval of the Merger
is  assured. In connection with the  Company's approval of the Merger Agreement,
the Board received the opinion of  John G. Kinnard & Company, Incorporated  that
both  the  aggregate  consideration of  $550,000  cash  to be  received  for all
outstanding shares of common stock of the  Company and the $.040 per share  cash
to  be received by the  Minority Shareholders in connection  with the Merger are
fair to the Minority Shareholders from a financial point of view.
 
    We hope you will be able to  attend the Special Meeting. Whether or not  you
plan  to attend, we urge you to complete, sign, date and return the accompanying
proxy in the enclosed business reply  envelope to make certain that your  shares
will be represented at the Special Meeting.
 
    Promptly  after the Merger,  a Letter of  Transmittal will be  mailed to all
shareholders of record to use in surrendering their Company stock  certificates.
PLEASE  RETAIN YOUR STOCK CERTIFICATE UNTIL  YOU RECEIVE A LETTER OF TRANSMITTAL
WHICH WILL INCLUDE INSTRUCTIONS AS TO THE  PROCEDURE TO BE USED IN SENDING  YOUR
CERTIFICATES.
 
                                          Sincerely,
 
                                          /s/ John P. Paumen

common stock, par value  $.15 per share ("Common  Stock"), has, pursuant to  the
Merger  Agreement, agreed to vote all shares of Common Stock held by it in favor
of the approval of the  Merger (unless such vote would  cause NCS to breach  its

effective time of the Merger.
 
    All proxies that are properly executed and received in a timely manner  will
be  voted  in  accordance  with the  instructions  noted  thereon.  Any properly
executed proxy which does not specify to the contrary will be voted in favor  of
the  approval of the  Merger Agreement described herein.  A shareholder giving a
proxy has the right to revoke it at  any time before it is voted by filing  with
the  Secretary of the Company a written  notice of revocation or a duly executed
later-dated proxy, or by attending the Special Meeting and voting in person.

SPECIAL MEETING
 
    A special meeting of shareholders of the Company will be held at the offices
of  the Company at 10901 Bren Road East, Minnetonka, Minnesota 55343, on Monday,
April 29, 1996, at 9:00  a.m., Minneapolis Time, to  consider and vote upon  the
proposed Merger.
 
DESCRIPTION OF MERGER
 
    Company  shareholders will  be asked  to consider  and vote  upon the Merger
Agreement by  and between  Newco, the  Company and  NCS, pursuant  to which  the
Company  will be merged  with and into Newco.  If the Merger  is approved and is
consummated, the Company will cease to exist and holders of Company Common Stock
will receive an aggregate  $550,000, of which NCS,  the holder of  approximately
85%  of  the Company's  outstanding Common  Stock, will  be entitled  to receive
$355,000, or approximately $.013 in exchange  for each share of Common Stock  it
holds,   and  the  shares   held  by  all   other  Shareholders  (the  "Minority
Shareholders") will be entitled to receive  $.040 in exchange for each share  of
Common Stock they hold, or approximately $195,000 in the aggregate. In addition,
Newco  shall  retire  existing  indebtedness  of DMI  to  NCS  represented  by a
promissory note dated March 31, 1995.  Upon consummation of the Merger,  holders
of  Company Common Stock will  have no continuing interest  in the future of the
Company or Newco. See "THE MERGER -- Terms of the Merger Agreement."
 
SHAREHOLDER APPROVAL OF MERGER AGREEMENT
 
    Under Minnesota law,  the affirmative  vote of at  least a  majority of  the
outstanding  shares of  DMI Common  Stock is required  to approve  and adopt the
Merger Agreement. NCS, which owns approximately 85% of the outstanding shares of
Common Stock, has, pursuant to the  Merger Agreement, agreed to vote all  shares
of  Common Stock held by it in favor  of the approval of the Merger (unless such
vote would cause NCS to breach  its fiduciary duties under applicable law).  NCS
has  indicated it intends to vote  in favor of the Merger,  and, if NCS votes in
such manner, approval  of the  Merger is  assured. See  "GENERAL INFORMATION  --

    The Board of Directors of DMI has unanimously approved the Merger Agreement,
having  determined  that the  Merger is  in the  best interests  of DMI  and its
shareholders. Among the factors considered by the Board in approving the  Merger
and  the Merger Agreement and in making  its recommendation were the current and
anticipated competitive environment and market  conditions in the industry,  the
Board's knowledge of DMI's current and anticipated business, financial condition
and  results  of operations,  the $.040  per share  to  be paid  in cash  to the
Company's Minority Shareholders and the approximately $.013 per share to be paid
in cash to  NCS, the  other terms  of the  Merger, and  the opinion  of John  G.
Kinnard  &  Company,  Incorporated  that  both  the  aggregate  consideration of
$550,000 cash to be received for all outstanding shares of Common Stock and  the
$.040  per share cash to be received  by the Minority Shareholders in connection
with the Merger are fair to the Minority Shareholders from a financial point  of
view.  See "THE MERGER -- Background of the Merger" and "THE MERGER -- Basis and
Reasons for the Merger; Recommendation."
 
OPINION OF INVESTMENT BANKER
 
    DMI's investment banker, John G. Kinnard & Company, Incorporated ("Kinnard")
has rendered an opinion to the Board of Directors of DMI that both the aggregate
consideration of $550,000  cash to  be received  for all  outstanding shares  of
Common   Stock   and   the   $.040   per   share   cash   to   be   received  by
 
                                       4

the Minority Shareholders in connection with the Merger are fair to the Minority
Shareholders from  a financial  point of  view. See  "THE MERGER  -- Opinion  of
Investment Banker" and the copy of such opinion annexed hereto as Appendix B.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER AND RELATED TRANSACTIONS
 
    At  December 31, 1995, John P. Paumen, a member of the Board of Directors of
DMI, beneficially owned 62,361 shares, or  0.2% of all outstanding Common  Stock
of  the Company, excluding options (all of  which have exercise prices in excess
of the  per  share  cash  consideration  to  be  paid  pursuant  to  the  Merger
Agreement).  Pursuant to the Merger Agreement, approximately $2,495 will be paid
with respect to  the shares of  Common Stock beneficially  owned by Mr.  Paumen.
Adrienne  T. Tietz and Mark D. Holman,  the only other directors of the Company,
do not beneficially own  any shares of  Common Stock. However,  Ms. Tietz is  an
executive  officer of NCS, the Company's majority shareholder, and Mr. Holman is
an employee of NCS and provides the  services of Chief Financial Officer to  the
Company  under a contract  between the Company  and NCS. Pursuant  to the Merger
Agreement, NCS will receive  an aggregate $355,000,  or approximately $.013  per
share,  for its shares of Common Stock.  In connection with the Merger, Newco or
DHT has agreed to (i) pay to NCS the balance outstanding at the time of  Closing
under  a promissory note between the Company and NCS (estimated to be $542,000),
(ii) obtain  the  release  of NCS  from  its  guarantee of  the  Company's  bank
indebtedness,  (iii)  assume guarantees  provided  by NCS  of  performance under
certain customer service contracts and (iv) obtain releases of NCS from  certain
customer  and bank  lease commitments. In  the event  Newco or DHT  is unable to
secure the release of NCS from  such customer and bank lease commitments,  Newco
or  DHT  has  agreed  to  indemnify NCS  against  any  losses  relating  to such
commitments. See "THE MERGER -- Interests  of Certain Persons in the Merger  and
Related  Transactions" and  "BENEFICIAL OWNERSHIP OF  PRINCIPAL SHAREHOLDERS AND
MANAGEMENT."

RIGHTS OF DISSENTING SHAREHOLDERS
 
    Company shareholders have the right to dissent from the Merger and,  subject
to  certain conditions provided for under Minnesota law, are entitled to receive
payment of the "fair value" of  their Common Stock (herein "Appraisal  Rights").
Shareholders  will be bound  by the terms  of the Merger  unless they dissent by
complying with all of the requirements of Sections 302A.471 and 302A.473 of  the
Minnesota  Business Corporation  Act. Shareholders  wishing to  dissent from the
Merger must file with the Company, prior  to the vote at the Special Meeting,  a
written  notice of any intention to demand  the payment of fair compensation for
such shareholders' shares of Common Stock if the Merger is effectuated, and such
dissenting shareholders  must not  vote their  shares in  favor of  the  Merger.
Shareholders who fail to file such notice or vote in favor of the Merger will be
bound  by the  terms of  the Merger.  See "THE  MERGER --  Appraisal Rights" and
Appendix C which  is the  full text  of Sections  302A.471 and  302A.473 of  the
Minnesota Business Corporation Act.
 
FEDERAL INCOME TAX CONSEQUENCES OF MERGER
 
    Cash  paid to Company shareholders pursuant to the Merger or pursuant to the
exercise of Appraisal Rights  will be a taxable  transaction for federal  income
tax purposes and may also be a taxable transaction under applicable state, local
and  foreign tax laws. Shareholders are urged to consult their own tax advisors.

BUSINESS OF THE COMPANY PENDING MERGER
 
    The Company has agreed, pending consummation  of the Merger, to conduct  its
business  in the ordinary course consistent with  past practice and will use its
best efforts  to maintain  and  preserve intact  its business  organization  and
business  relationships  and  to  keep available  the  services  of  its present
officers and employees. The Company has also agreed to provide reasonable access
to its offices,  properties, books and  records to representatives  of Newco  in
connection with their evaluation of the business, assets and financial condition
and  prospects  of DMI.  See "THE  MERGER --  Terms of  the Merger  Agreement --
BUSINESS OF THE COMPANY PENDING THE MERGER."
 
PRICE RANGE OF DMI COMMON STOCK
 
    The Common  Stock trades  under the  symbol "DIMM"  in the  over-the-counter
market.  The price of  the Common Stock has  ranged from $.01  to $.12 per share
since January 1, 1995.  On December 7,  1995, the day  immediately prior to  the
public  announcement of the agreement between DMI  and Newco for the Merger, the
closing sale price per share for the Common Stock was $.03. The Board  believes,
based  on the  very small volume  of trading in  the DMI Common  Stock, that the
historical trading prices  are not  representative of the  selling prices  which
could  be expected for the sale of a  large number of shares of DMI Common Stock
and expects that  the anticipated selling  price for a  large number of  shares,
independent  of a transaction such  as the Merger, would  be much lower than the
historical prices.  See  "PRICE  RANGE  OF  COMMON  STOCK,  TRADING  VOLUME  AND
DIVIDENDS."

                              GENERAL INFORMATION
 
PURPOSE OF THE SPECIAL MEETING
 
    The  Special Meeting is being held at  9:00 a.m., Minneapolis Time, on April
29, 1996 at  the offices of  the Company  at 10901 Bren  Road East,  Minnetonka,
Minnesota  55343, to  consider and  act upon  a proposal  to approve  the Merger
Agreement pursuant to which Newco will acquire the Company.
 
    The Company's Board of Directors  has approved the Merger Agreement,  having
determined that the acquisition of the Company by Newco is in the best interests
of  the  Company and  its shareholders.  The  Board unanimously  recommends that
shareholders vote FOR approval of the Merger Agreement.
 
    Pursuant to and subject to the terms and conditions of the Merger Agreement,
on the Effective Date, NCS shall receive  in exchange for its DMI Common  Stock,
$355,000,  or approximately $.013  per share, and each  outstanding share of DMI
Common Stock held  by the  Minority Shareholders,  except those  shares held  by
Minority  Shareholders who validly  perfect Appraisal Rights,  will be converted
into the right  to receive  $.040 in  cash, without  interest, or  approximately
$195,000 in the aggregate.
 
VOTES REQUIRED AND OWNERSHIP
 
    Only  holders of record of Company Common  Stock at the close of business on
March 25, 1996 (the "Record Date"), are entitled to vote at the Special Meeting.
A quorum  for  purposes of  conducting  business at  the  Special Meeting  is  a
majority  of the  outstanding shares  of Common Stock  entitled to  vote. On the
Record Date,  the Company  had  outstanding 32,533,460  shares of  Common  Stock
entitled  to vote  at the Special  Meeting. Each  holder of Common  Stock on the
Record Date is entitled to one vote  for each share held. The affirmative  vote,
in  person or  by proxy,  of at least  a majority  of the  outstanding shares of
Common Stock entitled to vote at the Special Meeting is required to approve  and
adopt the Merger Agreement.
 
    Abstentions  will be treated as shares that are present and entitled to vote
for purposes of  determining the presence  of a quorum  and in tabulating  votes
cast  on proposals  presented to  shareholders, but  as unvoted  for purposes of
determining the approval of  the matter. Consequently,  an abstention will  have
the  same effect as a negative vote. If  a broker indicates on the proxy that it
does not  have  discretionary  authority as  to  certain  shares to  vote  on  a
particular  matter, those shares will not  be considered as present and entitled
to vote with respect to that matter.
 
    NCS, which owns approximately 85% of the outstanding shares of Common Stock,
has, pursuant to the Merger Agreement, agreed to vote all shares of Common Stock
held by it in favor of the approval of the Merger (unless such vote would  cause
NCS  to breach its fiduciary duties under  applicable law). NCS has indicated it
intends to  vote in  favor of  the Merger,  and, if  NCS votes  in such  manner,
approval of the Merger is assured.
 
    If  the Merger is not  consummated, the Company expects  to continue to seek
merger or  corporate  partnering  opportunities  while  operating  generally  in
accordance with the description of the business set forth under "BUSINESS OF THE
COMPANY" herein.
 
                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
    On  December 17, 1993, the shareholders of the Company approved the issuance
of (i)  27,533,441  shares of  Common  Stock to  NCS  resulting in  NCS  holding
approximately  85%  of the  then  outstanding shares  of  the Company,  and (ii)
1,326,673 shares of Common Stock to the Company's Employee Stock Ownership  Plan
(the  "ESOP"),  resulting  in the  ESOP  holding  approximately 5%  of  the then
outstanding shares of  Common Stock,  pursuant to  an agreement  with NCS  which
provided  for, among other  things, the elimination of  a significant portion of
the Company's outstanding indebtedness  to NCS. At  the closing, $4,857,000  was
outstanding  and  of  this  amount,  only  $1,105,000  was  carried  forward and
converted to a  long-term note.  This indebtedness resulted  from the  Company's
inability  to repay  trade accounts  payable and notes  payable to  NCS. To that
point, the Company had operating
 
                                       8
<PAGE>
losses and had struggled to meet  its financial obligations in every year  since
inception.  A primary motivation for converting the NCS indebtedness into Common
Stock was  to  improve the  Company's  balance  sheet to  facilitate  sales  and
marketing  efforts, which the Company believed had been severely hampered by its
financial position, and continuing uncertainty about its ability to continue  as
a going concern.
 
    Faced  with continuing losses from operations  and a continuing inability to
honor its repayment  obligations to NCS,  in May 1992,  the Company engaged  the
services  of an investment banking firm to  seek a strategic partner or investor
to acquire  80  to  90  percent  of the  Company,  with  the  proceeds  of  such
acquisition  to  be  used  to  repay the  outstanding  debt  to  NCS.  During an
approximately one-year period of seeking such strategic partner or investor, the
investment banking  firm approached  approximately 40  to 50  entities, and  the
Company had direct discussions with approximately 10 to 12 entities. By December
1993, none of the entities had offered acceptable proposals.
 
    Subsequent  to shareholder approval of the  NCS debt restructuring and stock
issuance, the engagement of the investment banking firm was extended to December
31, 1994, and the  firm continued to seek  purchasers or strategic partners  for
the  Company. By May  1994, a list  of primary and  secondary companies had been
targeted as potential purchasers or  partners and revised descriptive  materials
had  been forwarded  and contacts  initiated. By December  31, 1994,  it was the
opinion of the Company's  Board of Directors (the  "Board") that the efforts  of
the  investment banking firm were unlikely to result in a firm proposal from any
of the potential partners  or purchasers and the  agreement with the  investment
banking  firm, in accordance with  its terms, was allowed  to terminate with the
exception of a provision in the agreement which permitted the firm to receive  a
commission  if the Company were to enter  into a definitive agreement or close a
transaction on or before December 31, 1995.
 
    Beginning in July 1995, the Board began contacting previously identified and
new potential purchasers to determine whether there was any renewed interest  in
acquiring  the  Company. By  the end  of October  1995, two  companies submitted
non-binding expressions of interest in  pursuing transactions with the  Company,
one from DHT to acquire all of the outstanding Common Stock through a merger and
the  other from a company within the same general industry (the "Other Company")
to acquire all of the assets and certain of the liabilities of the Company.
 
    On November 2, 1995, the  Board met to consider  the proposals from DHT  and
the  Other  Company.  DHT proposed  to  acquire all  of  the NCS  shares  for an
aggregate purchase price of $300,000, or  approximately $.01 per share, and  the
shares  held by the Minority Shareholders (including the ESOP) for approximately
$.02 per share, in addition to prepaying  or assuming the remaining debt of  the
Company  to NCS, reaching an agreement with  the Company's bank whereby the bank
would release  NCS from  its corporate  guarantee of  Company indebtedness,  and
agreements  pursuant to  which DHT  would assume  commitments by  NCS to service
customers of the Company, and release of NCS from certain lease commitments. The
Other Company proposed to acquire all of  the assets of the Company and  certain
liabilities,  including  those  associated  with  NCS,  with  the  result  that,
according to then current assumptions regarding the Company's balance sheet, the
Company's shareholders would  all receive less  than $.01 per  share. The  Board
reviewed the background of both proposals, the viability and likelihood that the
proposals  could be consummated and  other factors related to  DHT and the Other
Company, the proposals and  the resulting impact  on the Company's  shareholders
and  on-going  business.  Concern was  expressed  by the  Board  respecting both
proposals  and  representatives  of  the   Company  were  directed  to   contact
representatives of DHT and the Other Company to further explore the proposals.
 
    Between  November 2  and November 21,  1995, representatives  of the Company
communicated to the Other Company that the Directors were concerned that without
acquiring all of  the liabilities, and  following a liquidation  of the  Company
after  a  sale  of all  of  the  assets, there  would  be  insufficient proceeds
available  for  any  distributions  to   shareholders.  As  a  result  of   such
negotiations,  the  Other  Company increased  its  offer to  guarantee  that the
Minority Shareholders would receive $42,250 in the
 
                                       9
<PAGE>
aggregate, or $.008 per share. The proposal contemplated that the Other  Company
would  manage  the  business pending  the  closing,  that the  Company  would be
prohibited from discussing any further  transactions with any other parties  and
would  be obligated to  pay the Other Company  $50,000 as a  break-up fee if the
Company were to sell its business to another entity within the succeeding twelve
(12) months and required  NCS to unconditionally agree  to vote their shares  in
favor  of the  transaction. The Board  was concerned that  the asset acquisition
structure in the proposal from the Other Company would result in excessive costs
following the transaction  in winding up  the business of  the Company.  Between
November  2  and  November  21, 1995,  representatives  of  the  Company further
investigated the financial condition and  background of DHT and encouraged  both
parties to increase their proposed purchase prices.
 
    On  November 21, 1995,  the Board met  again to consider  the two proposals.
Following review of both  proposals, the Board decided  to advise both  entities
that  they should make their best and final offer prior to the close of business
on November 22, 1995 and that the Board would meet again on November 24, 1995 to
consider such final proposals and decide which to accept.
 
    At the end  of the  day on  November 22,  1995, the  Other Company  verbally
indicated  it  would be  willing  to revise  its  proposal to  reflect  a merger
transaction rather  than an  acquisition of  assets and  to guarantee  that  the
Minority  Shareholders would receive  an aggregate $125,000,  or $.025 per share
and that  NCS would  receive  $230,000, or  approximately  $.008 per  share.  On
November  24, 1996,  the Board  considered the proposal  from DHT  and the Other
Company, expressed concern that DHT had not completed a pending recapitalization
financing which would be  necessary to fund its  proposal and observed that  the
aggregate price paid the Minority Shareholders in the Other Company proposal was
higher  than  the  price paid  by  DHT.  As a  result,  the  Board preliminarily
concluded that it  would be more  beneficial to the  shareholders to accept  the
proposal  from the Other Company and requested  that the Other Company provide a
written revision of its proposal. Subsequent to the meeting, representatives  of
the  Company communicated  its conclusions  to the  Other Company  and the Other
Company indicated it would submit a revised non-binding letter of intent.
 
    On November 27,  1995, the  Other Company  furnished the  Company a  revised
non-binding  letter of intent which reflected  a merger transaction and included
conditions to consummation of the merger related to the minimum amount of assets
and maximum amount of liabilities of  the Company, limitations on the amount  of
expenses  allowed  in  connection  with  the  shareholder  approval  process, an
increase in  the  break-up fee  from  $50,000 to  $100,000,  a limited  form  of
fiduciary-out  which would allow the Board  to consider alternative offers which
might yield the shareholders  more value for their  stock and other terms  which
representatives of the Company determined were unacceptable. Between November 27
and   December  1,  1995,   representatives  of  the   Company  negotiated  with
representatives of the  Other Company  the terms  of the  non-binding letter  of
intent  without  success  in  achieving  terms  which  would  have  been  deemed
acceptable to the Board. During this  period, DHT indicated it would be  willing
to  revise  its  proposal  to increase  the  consideration  payable  to Minority
Shareholders from $.02 per share  to $.04 per share and  retire the NCS debt  at
closing  and increase  the cash  payment to  NCS from  $300,000 to  $355,000 (or
approximately $.013 per share). The Board also received confirmation from  DHT's
investors  that  DHT  was  about  to  complete  its  proposed  equity  financing
transaction. On December 1, 1995, following negotiation with representatives  of
the  Company, the Other  Company submitted its  final proposal in  the form of a
non-binding letter of intent  which reflected an aggregate  payment of $.025  to
Minority Shareholders, a $100,000 break-up fee, an exclusive dealing requirement
with  a  limited fiduciary-out  for  the Board  and  other provisions  which had
previously been deemed unacceptable  to the Board,  although the condition  with
respect  to  the  required  minimum  amount  of  assets  and  maximum  amount of
liabilities was eliminated.
 
    On December 4,  1995, the Board  met again to  consider the final  proposals
submitted  by DHT and the  Other Company and concluded  that the proposal by DHT
was superior in terms of consideration to the shareholders and DHT's willingness
to execute a merger transaction with  the maximum degree of probability that  it
would  be consummated. On December 5, 1995,  the Board signed a letter of intent
with DHT  on terms  which provided  for a  merger between  DHT and  the  Company
whereby NCS would
 
                                       10
<PAGE>
receive  an aggregate $355,000,  or approximately $.013  per share, the Minority
Shareholders would receive approximately $195,000,  or $.040 per share, and  DHT
would  deposit $50,000 to  be applied against the  aggregate purchase price. DHT
agreed to (i) pay to NCS the balance outstanding at the time of closing under  a
promissory note between the Company and NCS, (ii) obtain the release of NCS from
its  guarantee of  the Company's bank  indebtedness, (iii)  assume guarantees of
performance under certain customer service contracts and (iv) obtain releases of
NCS from  certain customer  and bank  lease commitments.  The proposal  did  not
require a break-up fee and was subject to a number of conditions including Board
approval  of a definitive agreement and, ultimately, shareholder approval of the
transaction.
 
    Between December 6  and December 21,  1995, the Other  Company expressed  to
representatives  of the Company its continuing desire to acquire the Company. On
December 11, 1995, the Other Company  proposed a total cash payment of  $700,000
($455,000   for  the  NCS   shares  and  $245,000   for  the  minority  shares).
Subsequently, on December  21, 1995,  the Other  Company proposed  a total  cash
payment  of $745,000 ($360,000 for the NCS  shares and $385,000 for the minority
shares). However,  the  communications were  made  in the  form  of  non-binding
letters  of intent and required additional  due diligence investigation prior to
making  a   formal   offer,   notwithstanding   repeated   communications   from
representatives  of the Company  that, given the executed  letter of intent with
DHT and the prior  unwillingness of the  Other Company to  revise its letter  of
intent  to reflect acceptable terms,  the Company would not  be in a position to
formally  entertain  any  communication  from  the  Other  Company  unless  such
communication  was in  the form of  a proposed definitive  merger agreement. The
Board concluded that the price  differential between the Other Company  proposal
and the DHT proposal was not sufficiently large to justify pursuing the proposal
from  the Other Company at the risk  of jeopardizing the executed DHT agreement.
The Other Company did not submit a definitive merger agreement for consideration
by the Board.
 
BASIS AND REASONS FOR THE MERGER; RECOMMENDATION
 
    The Board of Directors  of the Company has  unanimously approved the  Merger
Agreement  and  believes  that  the  Merger is  in  the  best  interests  of the
shareholders of the Company.  The Board of  Directors unanimously recommends  to
the  shareholders that they vote FOR approval of the Merger Agreement. The Board
believes that the Company, its shareholders and employees will benefit from  the
Merger.
 
    In  reaching these conclusions, the Board considered many factors including,
but not limited to, the following:
 
        (i) the terms of  the Merger Agreement, including  the $.040 to be  paid
    per share to the Company's Minority Shareholders and the approximately $.013
    to  be paid per share  to NCS and the fact  that such shareholders will have
    the opportunity to dispose of all Common Stock for cash, particularly  given
    the Board's observation that the market for trading the Common Stock is very
    limited in its volume capacity and that it is unlikely that an active market
    will develop;
 
        (ii)  the  current and  anticipated  competitive environment  and market
    conditions in the Company's industry and product markets, including (a)  the
    trend in the Company's industry towards consolidation making it increasingly
    difficult  for the Company,  which has limited  product offerings, to remain
    competitive, (b)  the  Company's  continuing decline  in  revenues  and  its
    inability  to meet not only existing  debt obligations but business expenses
    in the ordinary  course, (c) the  Company's lack of  cash resources to  fund
    necessary product upgrades and modifications to retain current market share,
    and  (d)  the favorable  response  of the  Company's  customers to  DHT, its
    products offerings and its management team;
 
       (iii) the Company's book value per common share, its historical  earnings
    and  cash flow, its  scheduled debt repayment  obligations and its projected
    inability to meet those obligations;
 
                                       11
<PAGE>
       (iv) the Company's persistently  weak cash flow and  its reliance on  NCS
    for  indebtedness guarantees, customer service  guarantees, trade credit and
    corporate support and the stated historical position of NCS that it does not
    intend to support the Company indefinitely;
 
        (v) the alternatives  to an  acquisition of  the Company  that might  be
    available,  including either attempting to remain as an independent company,
    notwithstanding its financial obstacles, or filing for protection under  the
    federal bankruptcy laws;
 
       (vi) the ability and willingness of DHT to consummate the Merger promptly
    and the availability of sufficient cash to do so;
 
       (vii)  the ability of  DHT to contribute to  the future growth, viability
    and success  of  the Company  in  a consolidating  industry  with  customers
    requiring  greater  depth  and resources  in  order to  enhance  and service
    products;
 
      (viii) the inadequate  nature of  the non-binding  indication of  interest
    expressed  by the Other Company,  which was the only  other party to express
    any firm  interest in  acquiring the  Company following  over two  years  of
    search  for a strategic partner or  purchaser, combined with the requirement
    of the Other  Company that  DMI commit to  a $100,000  "bust-up" fee,  which
    would  effectively  prohibit  consideration  and  acceptance  of  any  other
    proposals, including the DHT proposal;
 
       (ix) the opinion  of Kinnard  with respect to  the fairness  of both  the
    aggregate  consideration of $550,000 cash to be received for all outstanding
    shares of common stock  of the Company  and the $.040 per  share cash to  be
    received  by the  Minority Shareholders in  connection with  the Merger. See
    "Opinion of Investment Banker," below; and
 
        (x) the interests of the Company's employees, customers, and creditors.
 
    The Board approval and  recommendation of the  Merger were conditioned  upon
receipt  of an opinion of  an investment banker with  respect to the fairness of
the aggregate $550,000 to be received by DMI's shareholders and, in  particular,
the  $.040 to be  received by the  Minority Shareholders in  the Merger. DMI has
received the  opinion  of  Kinnard  that both  the  aggregate  consideration  of
$550,000  cash to be received for all  outstanding shares of common stock of the
Company and the $.040 per share cash to be received by the Minority Shareholders
in connection  with the  Merger are  fair to  the Minority  Shareholders from  a
financial point of view. See "Opinion of Investment Banker," below.
 
    In  view of the  wide variety of  factors considered in  connection with its
evaluation of  the Merger,  the Board  did  not find  it practicable  to  assign
relative weights to the specific factors considered in reaching its decision.
 
TERMS OF THE MERGER AGREEMENT
 
    The following description of certain terms of the Merger Agreement is only a
summary and does not purport to be complete. This discussion is qualified in its
entirety  by reference to the complete text of the Merger Agreement set forth in
Appendix A hereto.
 
    THE MERGER TRANSACTIONS.  DHT incorporated Newco, a corporation in which DHT
holds all of  the outstanding  stock, solely for  the purpose  of effecting  the
Merger.  Newco is not currently engaged in  any other business. Under the Merger
Agreement, Newco is to be merged with and into the Company, with Newco being the
surviving corporation.  The Company  will  cease to  exist. The  Certificate  of
Incorporation  and By-Laws of  Newco in effect  at the time  such merger becomes
effective shall  become the  Certificate  of Incorporation  and By-Laws  of  the
surviving corporation.
 
    NCS, which owns approximately 85% of the outstanding shares of Common Stock,
has, pursuant to the Merger Agreement, agreed to vote all shares of Common Stock
held  by it in favor of the approval of the Merger (unless such vote would cause
NCS to breach its fiduciary duties  under applicable law). NCS has indicated  it
intends  to vote  in favor  of the  Merger, and,  if NCS  votes in  such manner,
approval of the Merger is assured.
 
                                       12
<PAGE>
    CONVERSION OF COMMON STOCK.  Shares of DMI Common Stock shall continue to be
transferable until the Effective Date. Pursuant to and subject to the terms  and
conditions of the Merger Agreement, on the Effective Date each outstanding share
of Common Stock held by Minority Shareholders, except those held by shareholders
who  validly  perfect Appraisal  Rights,  will be  converted  into the  right to
receive $.040 in cash, without interest. Each outstanding share of Common  Stock
owned  by NCS will on the Effective Date  be converted into the right to receive
approximately $.013 in cash, or $355,000 in the aggregate, without interest. See
"BUSINESS  OF  THE  COMPANY."  The   aggregate  consideration  payable  to   DMI
shareholders pursuant to the Merger Agreement is approximately $550,000.
 
    EFFECTIVE DATE.  The Effective Date of the Merger, on which date the closing
of  the Merger  will occur and  the conversion  of the Common  Stock will become
effective, will be the date  set forth in the articles  of merger as filed  with
the  Secretary of State of the States of Minnesota and Florida. This filing will
occur as soon as practicable following  the approval of the Merger Agreement  by
the  shareholders of the Company and  the satisfaction of other conditions under
the Merger Agreement. The Effective Date is currently expected to take place  at
11:59  p.m., Minneapolis Time, on April 29,  1996. Consummation of the Merger is
subject to  certain  conditions.  See "TERMINATION  RIGHTS;  CONDITIONS  TO  THE

authorization and authority to enter into and perform its obligations under  the
Merger  Agreement and its good and marketable  title to the shares of DMI Common
Stock it owns, free  and clear of  claims or encumbrances of  any kind. NCS  has

warranties of the Company  are true. NCS has  agreed to indemnify Newco  against
certain losses with respect to such representations and warranties.
 
    TERMINATION RIGHTS; CONDITIONS TO THE MERGER.  The Merger Agreement provides

on the other hand, for the reasons set forth below.
 
    Either the  Company, on  the one  hand, or  Newco, on  the other  hand,  may

(provided that a  failure of  the party seeking  to terminate  the Agreement  to
fulfill  any of its obligations  under the Merger Agreement  shall not have been
the reason that  the Merger  has not  yet been  consummated); (iii)  any law  or
regulation  makes consummation of the Merger  illegal or otherwise prohibited or
any judgment, injunction, order  or decree enjoining the  Company or Newco  from
consummating  the  Merger is  entered and  such  judgment, injunction,  order or
decree shall become final and nonappealable;  or (iv) the vote of the  Company's
shareholders fails to adopt and approve the Merger Agreement.

other things,  that pending  consummation  of the  Merger, unless  Newco  agrees
otherwise,  the  Company  shall  conduct its  business  in  the  ordinary course
consistent with past  practice and  will use its  best efforts  to maintain  and

Company, the Escrow Fund shall be payable to the Company in the event the Merger

Merger Agreement.
 
OPINION OF INVESTMENT BANKER
 
    GENERAL.   After completing  the majority of the  negotiations of the Merger
Agreement but prior to execution of the Merger Agreement, the Board of Directors
of the  Company retained  Kinnard to  render  its opinion  with respect  to  the
fairness from a financial point of view of the cash consideration to be received
by the Company's Minority Shareholders pursuant to the Merger Agreement. Kinnard
was  first contacted by  the Company on October  31, 1995, at  which time it was
informed about  the pending  transaction  and was  asked  to submit  a  proposed
engagement  letter for  purposes of providing  a fairness  opinion in connection
with the pending transaction. Kinnard did  not determine the amount of the  cash
consideration  to be received by the shareholders  of the Company in the Merger.
In requesting Kinnard's opinion, the Board  of Directors of the Company did  not
give any special instructions to or impose any limitations upon the scope of the
investigation which Kinnard might wish to
 
                                       14
<PAGE>
conduct  to enable it to give its  opinion. Kinnard has delivered to the Company
its written opinions, respectively dated February  5, 1996 and the date of  this
Proxy  Statement, to the effect that, based  upon and subject to the matters set
forth therein, as of those dates,  both the aggregate consideration of  $550,000
cash  to be received for  all outstanding shares of  common stock of the Company
and the $.040  per share cash  to be  received by the  Minority Shareholders  in
connection  with  the  Merger  are  fair to  the  Minority  Shareholders  from a
financial point of view.
 
    In preparing its opinion as to the fairness of the consideration to be  paid
pursuant  to the Merger from a financial point of view, Kinnard has, among other
things, reviewed and studied publicly  available information regarding DMI,  the
Merger  Agreement and various  other information provided  by management of DMI.
Representatives of Kinnard have visited DMI's facilities and have discussed  the
current business environment and the business and financial outlook for DMI with
management  of  DMI.  Kinnard  has analyzed  the  historical  market  prices and
earnings of  the  Common Stock,  as  well  as profitability,  rates  of  return,
capitalization,  dividends and other relevant factors. Kinnard has also reviewed
the terms of  selected relevant mergers  and acquisitions and  has analyzed  the
general  economic outlook of  companies involved in  the health care information
systems  and  product  industries.   Kinnard  has  relied  without   independent
verification  upon the accuracy and completeness  of all the financial and other
information reviewed by Kinnard for purposes  of their opinion. Kinnard has  not
made an independent appraisal of DMI's assets and expressed no opinion regarding
the liquidation value of DMI. In connection with the opinion of Kinnard, DMI did
not  impose any limitation on the  scope of Kinnard's investigation with respect
to the business and financial condition of DMI.
 
    Kinnard is an investment  banking firm engaged, among  other things, in  the
valuation  of businesses  and their  securities in  connection with  mergers and
acquisitions, underwriting and  secondary distributions  of securities,  private
placements  and valuation for estate, corporation  and other purposes. The Board
of Directors  selected  Kinnard to  provide  the opinion  because  of  Kinnard's
experience  in  providing investment  banking  and financial  advisory services.
Other than  providing this  opinion,  Kinnard has  not provided  any  investment
banking  services on behalf of  DMI. However, Kinnard has  in the past performed
valuations relating to DMI exclusively for NCS.
 
    THE FULL  TEXT OF  THE  OPINION OF  KINNARD DATED  THE  DATE OF  THIS  PROXY
STATEMENT IS ATTACHED HERETO AS APPENDIX B. THE FOLLOWING SUMMARY OF THE KINNARD
OPINION  IS  QUALIFIED IN  ITS ENTIRETY  BY REFERENCE  TO THE  FULL TEXT  OF THE
KINNARD OPINION. DMI SHAREHOLDERS ARE URGED TO READ THE OPINION IN ITS  ENTIRETY
FOR  A  COMPLETE DESCRIPTION  OF THE  ASSUMPTIONS  MADE, MATTERS  CONSIDERED AND
LIMITS OF THE REVIEW  UNDERTAKEN. THE ASSUMPTIONS  MADE, MATTERS CONSIDERED  AND
LIMITS  OF THE REVIEW UNDERTAKEN CONTAINED IN THE OPINION DATED FEBRUARY 5, 1996
ARE SUBSTANTIALLY THE SAME AS THOSE CONTAINED  IN THE OPINION DATED THE DATE  OF
THIS PROXY STATEMENT AND ATTACHED HERETO AS APPENDIX B.
 
    In  arriving  at its  opinion, Kinnard  reviewed,  analyzed and  relied upon
material that bears upon the financial and operating condition and prospects  of
DMI  and material  prepared in connection  with the Merger,  and considered such
financial and other factors  as it deemed  appropriate under the  circumstances,
including, among other things, the following: (i) a draft dated January 29, 1996
of  the  proposed Merger  Agreement  by and  between  DMI, DHT  and  Newco; (ii)
publicly available information on DMI,  including annual and quarterly  reports,
proxy  statements, stock  price and  volume history  and recent  press releases;
(iii) financial projections  prepared by  DMI; (iv) the  historical pricing  and
trading  activity for  DMI; and (v)  conducted such other  studies, analyses and
inquiries as  Kinnard deemed  appropriate. Kinnard  also held  discussions  with
senior  management for DMI concerning its  past and current business operations,
the background and rationale for  the proposed Merger, the financial  condition,
operating  performance,  balance  sheet  characteristics  and  prospects  of the
business. In addition, in connection with  rendering its opinion dated the  date
of  this Proxy Statement,  Kinnard reviewed the  executed Merger Agreement dated
February 5, 1996 and this Proxy Statement.
 
    Kinnard believes that its  analyses must be considered  as a whole and  that
selecting  portions of its analyses without considering all factors and analyses
would create an  incomplete view of  the analyses and  process underlying  their
opinion.   Any  estimates  contained  therein  are  not  necessarily  indicative
 
                                       15
<PAGE>
of actual values, which may be significantly more or less favorable than as  set
forth therein. No company or transaction used as a comparison in the analyses is
identical to DMI or to the Merger. Because such estimates are inherently subject
to  uncertainty,  neither the  DMI Board,  Kinnard or  any other  person assumes
responsibility for the accuracy of such estimates.
 
    In preparing its opinion, Kinnard indicated it did not perform a  discounted
cash  flow analysis in view of the significant uncertainty concerning the future
financial solvency  of  DMI  (considering  DMI's  projected  inability  to  make
scheduled  payments on its promissory note due  NCS and the absence of free cash
flow).  Consequently,  a  discounted  cash  flow  analysis  was  not  considered
meaningful.
 
    Kinnard  reviewed the  trading volume  and trading  price of  the DMI Common
Stock on  a  daily  and monthly  basis  since  January 2,  1995.  This  analysis
indicated  extremely sporadic and small trading volumes in the DMI Common Stock.
Throughout the period  until the December  8, 1995 date  of announcement of  the
signing  of a  non-binding letter  of intent with  DHT relating  to the proposed
Merger, the low trading price ranged from  $.02 per share to $.10 per share  and
the  high trading price  ranged from $.02 per  share to $.12  per share, with an
average low of $.04  and an average  high of $.04.  Kinnard indicated that  very
small shifts in price resulted in high percentage shifts, due to the low trading
values of the Company's Common Stock. Furthermore, given the lack of significant
volume  and research coverage, Kinnard indicated  the market was inefficient and
the price was  not a good  indicator of value.  However, the analysis  indicated
that the price paid Minority Shareholders was generally within the trading range
of the DMI Common Stock.
 
    Kinnard  reviewed selected transactions deemed  relatively comparable to the
Merger, which were  acquisitions of unprofitable  businesses by publicly  traded
companies  where the transaction  size was between  $500,000 and $3,000,000. The
analysis of these  52 transactions  included a comparison  of the  value of  the
transaction  (considered the  payment for equity  plus debt) as  compared to the
target's sales (the "value/sales")  and an analysis of  the offering price  (the
amount paid for the target's equity) as compared to the target's book value (the
"offering  price/book  value"). The  analysis  indicated a  mean  value/sales of
65.55% and a  median value/sales  of 42.25% and  of a  mean offering  price/book
value  of  2.2x and  a median  offering  price/book value  of 1.35x.  The Merger
value/sales  when  considering  the  total   offer  to  NCS  and  the   Minority
Shareholders  was  41.03%  and the  offering  price/book value  was  3.59x. When
considering the consideration paid to the Minority Shareholders, the value/sales
was 55.32%,  well within  the range  of  mean and  median value/sales,  and  the
offering  price/book value  was 8.51x,  well in  excess of  the mean  and median
offering price/book value. Kinnard also screened for transactions in the  health
care  information  industry,  but  determined  that  the  transactions  were not
relevant to  the  Merger  because  they  either  involved  companies  that  were
significantly  larger  and financially  stronger than  DMI or  were transactions
involving  private  companies  where  reliable  financial  information  was  not
available.
 
    Kinnard also reviewed in connection with its analyses, various trends in the
industry which reflected a consolidating industry where customers were demanding
greater  resources and services from suppliers  and compared that trend to DMI's
declining sales, need for product upgrades, financial insecurity and the adverse
impact of  limited  product development  and  support. In  connection  with  the
industry  review,  Kinnard also  analyzed the  financial performance  and market
valuations for selected publicly traded companies which compete with the Company
in the health care information technology industry. All of theses companies  are
significantly  larger and  financially stronger  than the  Company. Kinnard also
reviewed the process whereby DMI conducted a thorough search for a purchaser  or
strategic  partner which resulted in  negotiations with two potential purchasers
and a final  proposal which yielded  the maximum consideration  to the  Minority
Shareholders  available from potential acquirors. This process, combined with an
analysis of DMI's prospects without  a sale or strategic partnering  arrangement
(which  indicated that a wind-down scenario of the Company's affairs as prepared
by DMI management  would yield  no consideration  to the  shareholders), was  an
important  justification for  fairness, from a  financial point of  view, of the
Merger.
 
                                       16
<PAGE>
    DMI has agreed  to pay  Kinnard a fee  equal to  $25,000, including  $15,000
which  has previously been paid and $10,000 being paid on the date of this Proxy
Statement. This fee was not contingent on  the ability of Kinnard to render  its
opinion  relating to  the Merger.  DMI has agreed  to reimburse  Kinnard for its
reasonable out-of-pocket  expenses.  DMI has  also  agree to  indemnify  Kinnard
against  certain  liabilities to  which  Kinnard may  become  subject, including
liabilities under the federal securities laws.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER AND RELATED TRANSACTIONS
 
    As of December 31, 1995, John P. Paumen, a member of the Board of  Directors
of  DMI, beneficially  owned 62,361  shares, or  0.2% of  all outstanding Common
Stock of the Company,  excluding options (all of  which have exercise prices  in
excess  of the per  share cash consideration  to be paid  pursuant to the Merger
Agreement). Pursuant to the Merger Agreement, approximately $2,495 will be  paid
with  respect to the  shares of Common  Stock beneficially owned  by Mr. Paumen.
Adrienne T. Tietz and Mark D. Holman,  the only other directors of the  Company,
do  not beneficially own  any shares of  Common Stock. However,  Ms. Tietz is an
executive officer of NCS, the Company's majority shareholder, and Mr. Holman  is
an  employee of NCS and provides the  services of Chief Financial Officer to the
Company under a Services Agreement dated as of June 1, 1994, as amended, between
the Company and  NCS. The directors  will have no  further association with  DMI
after the Merger.
 
    As  of December 31, 1995, NCS held  27,653,441 shares of Common Stock in the
aggregate, or 85% of all outstanding shares, and, accordingly, has a significant
interest in the Merger.  Pursuant to the Merger  Agreement, NCS will receive  an
aggregate  $355,000, or  approximately $.013  per share,  for its  shares of DMI
Common Stock. In connection with the Merger, Newco or DHT has agreed to (i)  pay
to  NCS the balance outstanding  at the time of  closing under a promissory note
between the Company and NCS (estimated to be $542,000), (ii) obtain the  release
of  NCS from its guarantee  of the Company's bank  indebtedness in the amount of
$500,000, (iii) assume guarantees provided  by NCS of performance under  certain
customer service contracts and (iv) obtain releases of NCS from certain customer
and  bank lease commitments. In  the event Newco or DHT  is unable to secure the
release of NCS from such customer and  bank lease commitments, Newco or DHT  has
agreed  to indemnify  NCS against any  losses relating to  such commitments. See
"Employee Benefit Plans; Employment Agreements" below and "BENEFICIAL  OWNERSHIP
OF PRINCIPAL SHAREHOLDERS AND MANAGEMENT."
 
EMPLOYEE BENEFIT PLANS; EMPLOYMENT AGREEMENTS
 
    All  of the options granted under DMI's 1983 Employee Incentive Stock Option
Plan (the "1983 Plan") and DMI's 1987 Employee Incentive Stock Option Plan  (the
"1987  Plan") and outstanding as of the  Effective Date will be terminated as of
the Effective Date. At December 31, 1995, there were outstanding under the  1983
Plan  and 1987  Plan options  to purchase  186,750 and  49,500 shares  of Common
Stock, respectively. The exercise prices of such options range from $.25 to $.34
per share. As of December  31, 1995, all executive  officers and directors as  a
group  (3 persons) held incentive stock options  to purchase 25,000 shares at an
average exercise price of $.30 per share.
 
    Employees participating in the DMI  Employee Stock Ownership Plan and  Trust
(the "ESOP Plan") will also receive cash payments in connection with the Merger.
The total cash amount payable to all employees upon termination of the ESOP Plan
is  estimated to be $65,067, including approximately $2,414 payable to executive
officers and directors as a group.
 
    Except as described above and in "Interests of Certain Persons in the Merger
and Related  Transactions.", no  director or  officer of  DMI has  any  material
direct  or indirect interest in the Merger. For additional information regarding
DMI stock options, see Note 5 to the Company's Financial Statements included  in
the Company's Annual Report on Form 10-K which accompanies this Proxy Statement.

SURRENDER OF STOCK CERTIFICATES
 
    As  soon as  practicable after the  Effective Date,  Norwest Bank Minnesota,
N.A.  (the  "Paying  Agent")  will  mail  a  transmittal  form  (a  "Letter   of
Transmittal")  to each  holder of  DMI Common  Stock of  record at  the close of
business on  the Effective  Date, advising  such holder  of the  procedures  for
surrendering  to the Paying Agent any such certificates for exchange. If payment
is to be made to a person other than the person in whose name the certificate is
registered, the person requesting such payment  shall pay any transfer or  other
taxes  required by  reason of  such payment  in a  name other  than that  of the
registered holder or must establish to the satisfaction of the Paying Agent that
such tax either has been paid or is not applicable.
 
    The  Paying  Agent  will  not  accept  unsurrendered  certificates  formerly
representing  Common  Stock  more  than six  months  after  the  Effective Date.
Following such period, Newco, as the  surviving corporation of the Merger,  upon
proper  surrender to  it of  any unsurrendered  certificates and  other required
documents, will pay to the record holder of such shares the consideration to  be
paid  in the Merger.  If any certificates  representing any such  shares are not
surrendered prior to three years after the Effective Date (or immediately  prior
to  such earlier date  on which any  payment in respect  thereof would otherwise
escheat to  or become  the property  of any  governmental unit  or agency),  the
payment  in  respect of  such  certificates shall,  to  the extent  permitted by
applicable law, become the property  of Newco, free and  clear of all claims  or
interest of any person previously entitled thereto.
 
    No interest will accrue or be paid on the cash payable upon the surrender of
such   certificates.  From  and  after  the   Effective  Date,  the  holders  of
certificates evidencing ownership of shares of  Common Stock will cease to  have
any  rights  with  respect to  such  shares,  except the  right  to  receive the
consideration to be  paid in  the Merger  and any  rights provided  by law.  See
"Appraisal Rights" below.
 
    Upon the surrender and exchange of certificates by a shareholder, the holder
will  be paid, without interest thereon, the amount of cash to which such holder
is entitled under  the Merger  Agreement, less only  any amount  required to  be
withheld under applicable backup withholding federal income tax regulations. See
"Certain  Federal  Income Tax  Consequences" below.  CERTIFICATES SHOULD  NOT BE
SURRENDERED UNTIL THE LETTER OF TRANSMITTAL IS RECEIVED.
 
DEREGISTRATION OF COMPANY COMMON STOCK
 
    If the Merger is consummated, DMI Common  Stock will no longer be traded  on
the  over-the-counter market. After  the Effective Date, Newco  on behalf of DMI
will undertake to deregister the Common Stock under the Securities Exchange  Act
of 1934.
 
SOURCE OF FUNDS
 
    The  funds for the transaction will come from the cash resources of DHT. See
"BUSINESS OF DHT."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The receipt of cash by a DMI shareholder pursuant to the Merger or  pursuant
to  the exercise  of Appraisal  Rights will  be a  taxable transaction  for such
shareholder  for  federal  income  tax  purposes  and  may  also  be  a  taxable
transaction  under applicable state,  local and foreign  tax laws. The following
summarizes the federal income tax consequences, under currently applicable  law,
to  a  shareholder who  is a  citizen or  resident  of the  United States  or is
otherwise subject to United States federal income taxation on a net income basis
other than (i) a shareholder who acquired Common Stock pursuant to the  exercise
of  stock options or otherwise as compensation; (ii) shareholders who own Common
Stock under  special  circumstances,  such  as  shareholders  that  hedge  their
investment  in Common Stock, pursuant to options in that stock or otherwise; and
(iii) shareholders subject to special tax rules, such as financial institutions,
tax-exempt organizations, insurance companies,  dealers in stock or  securities,
and  foreign corporations and  individuals who are not  citizens or residents of
the United States.
 
    A shareholder will recognize gain or  loss equal to the difference, if  any,
between  the amount of cash to be received pursuant to the Merger or pursuant to
the exercise of Appraisal Rights and the
 
                                       18
<PAGE>
adjusted  tax basis of the shares of  Common Stock exchanged. To the extent that
the shares of Common Stock exchanged are  held as capital assets, any such  gain
or  loss will be characterized as a capital  gain or loss for federal income tax
purposes. If the shares were held for more than one year, any such capital  gain
or  loss will be a long-term capital  gain or loss. Any capital gains recognized
pursuant to the Merger  will be subject to  tax. Currently, the maximum  federal
capital  gains tax  rate is  28% for individuals  and 35%  for corporations. Any
long-term capital losses recognized by a shareholder pursuant to the Merger will
be allowed to offset any long-term capital gains recognized by that  shareholder
during the taxable year. Individual shareholders also may offset up to $3,000 of
their  ordinary taxable income, if any,  by any capital losses recognized during
the taxable year. Individual shareholders may carryover indefinitely any  excess
capital  losses  incurred to  future taxable  years. Corporate  shareholders may
carry any excess capital  losses back to the  three preceding taxable years  and
forward to the five succeeding taxable years.
 
    Under  the backup withholding  rules contained in  the Internal Revenue Code
and its regulations, DMI or the Paying Agent may be required to withhold 20%  of
the gross amount of any payments to certain shareholders. In order to avoid such
backup  withholding, each shareholder (other than corporations and other persons
exempt from such backup  withholding) should provide the  Paying Agent with  the
shareholder's  taxpayer identification  number (i.e., social  security number or
employer identification number) in accordance with the instructions included  in
the Letter of Transmittal.
 
    THE  ABOVE DISCUSSION WITH RESPECT TO THE FEDERAL INCOME TAX CONSEQUENCES OF
THE MERGER IS FOR GENERAL INFORMATIONAL PURPOSES ONLY. SHAREHOLDERS ARE URGED TO
CONSULT THEIR OWN TAX ADVISORS IN  DETERMINING THE TAX CONSEQUENCES THAT MAY  BE
RELEVANT  TO THEM IN CONNECTION WITH THE  MERGER AND PURSUANT TO THE EXERCISE OF
APPRAISAL RIGHTS,  AS WELL  AS THE  APPLICATION  TO THEM  OF ANY  STATE,  LOCAL,
FOREIGN, OR OTHER TAX LAWS.
 
APPRAISAL RIGHTS
 
    Pursuant to Sections 302A.471 and 302A.473 (the "Sections") of the Minnesota
Business  Corporation Act,  holders of DMI  Common Stock are  entitled to assert
Appraisal Rights in connection with the  Merger and obtain payment of the  "fair
value"  of their DMI  Common Stock, provided that  such shareholders comply with
the requirements of the  Sections. The following is  a summary of the  statutory
procedures  to be followed by  holders of DMI Common  Stock electing to exercise
their Appraisal Rights in order to perfect such right under the Sections and  is
qualified  in its entirety by reference to  the Sections, the full text of which
is annexed  to  this Proxy  Statement  as Appendix  C.  The Sections  should  be
reviewed carefully by DMI shareholders who wish to assert their Appraisal Rights
or  who wish  to preserve the  right do so,  since failure to  comply with those
procedures will result in the loss of such Appraisal Rights.
 
    Holders of DMI  Common Stock  who elect  to exercise  Appraisal Rights  must
satisfy  each of the following  conditions: (i) such holders  must file with DMI
before the taking of the vote with respect to the Merger written notice of their
intention to demand  payment of the  fair value  of their shares  of DMI  Common
Stock (this written notice must be in addition to and separate from any proxy or
vote  against the Merger; neither  voting against nor a  failure to vote for the
Merger will constitute such  a notice within the  meaning of the Sections);  and
(ii)  such holders must not vote in favor  of the Merger (a failure to vote will
satisfy this requirement,  but a vote  in favor of  the Merger, by  proxy or  in
person,  will constitute  a waiver  of such  holder's Appraisal  Rights and will
nullify any previously filed  written notice of intent  to demand payment).  DMI
WILL CONSIDER A PROXY THAT IS RETURNED BY A DMI SHAREHOLDER WITHOUT INDICATING A
DIRECTION  AS TO HOW IT SHOULD BE  VOTED AS CONSTITUTING SUCH A WAIVER. Minority
Shareholders who fail to comply with either of these conditions will be entitled
to receive $.040 per share in cash as provided in the Merger Agreement, but will
have no Appraisal Rights with respect to their shares.
 
    All written  notices should  be addressed  to: Dimensional  Medicine,  Inc.,
10901  Bren Road  East, Minnetonka,  Minnesota 55343,  Attention: Secretary, and
filed before the taking of the vote on the
 
                                       19
<PAGE>
Merger at the Special Meeting and should be executed by, or with the consent of,
the holder of record. The notice must  reasonably inform DMI of the identity  of
the  shareholder  and  the intention  of  such shareholder  to  demand Appraisal
Rights. In the notice the shareholder's name  should be stated as it appears  on
the  stock certificates. A  notice may be  made by a  beneficial owner of shares
only if a written consent of the  shareholders of record is submitted to DMI  at
the time of or prior to the assertion of the right to appraisal.
 
    A  shareholder may not  assert Appraisal Rights  as to less  than all of the
shares of DMI Common Stock registered  in such shareholders's name, unless  such
shareholder  asserts such rights  with respect to  all the shares  of DMI Common
Stock beneficially owned by another person  (or persons) and discloses the  name
and address of such other person (or persons). In that event, such shareholder's
rights shall be determined as if the shares of DMI Common Stock as to which such
shareholder  has asserted Appraisal  Rights and his  or her other  shares of DMI
Common  Stock  were   registered  in  the   names  of  different   shareholders.
Accordingly,  if shares  of DMI  Common Stock are  owned of  record in fiduciary
capacity, such as by a trustee, guardian or custodian, execution of a notice  of
intent to demand payment must be made for all shares of DMI Common Stock held of
record by the fiduciary unless the fiduciary executes the notice with respect to
all  the  shares of  DMI Common  Stock  held on  behalf of  one  or more  of the
beneficiaries and discloses  the name and  address of each  person for whom  the
fiduciary is asserting Appraisal Rights.
 
    Similarly,  a record owner, such as a broker, who holds shares of DMI Common
Stock as a nominee for others, may exercise Appraisal Rights with respect to the
shares of DMI Common  Stock held for  one or more  beneficial owners, while  not
exercising  such  rights for  other beneficial  owners, so  long as  the nominee
exercises the Appraisal  Rights with  respect to all  the shares  of DMI  Common
Stock  held  by the  nominee on  behalf of  each beneficial  owner for  whom the
nominee has exercised the Appraisal Rights and discloses the name and address of
such beneficial owner for whom the  Appraisal Rights have been asserted. If  the
shares  of DMI Common Stock are owned of record by more than one person, as in a
joint tenancy or tenancy in common, such demand should be executed by or for all
joint tenants.
 
    After a vote  approving the  Merger, DMI will  give written  notice to  each
shareholder who has filed a written notice of intent to demand appraisal and who
did  not vote in favor of the Merger setting forth the address to which a demand
for payment and stock certificates must be sent by such shareholder in order  to
obtain  payment, the date by which they must be received and any restrictions on
transfer of uncertified shares that will  apply after the demand for payment  is
received.  This notice  shall also  include a form  for demanding  payment to be
completed by the  shareholder and  a request for  certification of  the date  on
which  the  shareholder  (or  the  person on  whose  behalf  the  shareholder is
asserting Appraisal Rights) acquired beneficial  ownership of the shares of  DMI
Common  Stock. Shareholders  who fail to  demand payment or  deposit their stock
certificates as required by the notice within 30 days after the notice is  given
will  irrevocably forfeit their Appraisal Rights and  will be bound by the terms
of the Merger.
 
    If a demand for payment and deposit of stock certificates is duly made by  a
shareholder  with DMI as required by the notice, then upon the Effective Date or
the receipt of the demand, whichever is later, DMI will remit to the shareholder
an amount which DMI estimates to be the  fair value of the shares of DMI  Common
Stock,  with  interest, if  any,  accompanied by:  (1)  DMI's balance  sheet and
statement of income for a fiscal year ending not more than 16 months before  the
effective  date  of  the  Merger, together  with  the  latest  available interim
financial statements; (2) an estimate by DMI of the fair value of the shares and
a brief description of the method used to reach the estimate; and (3) a copy  of
the  Sections,  and a  brief description  of  the procedures  to be  followed in
demanding supplemental payment.  For the  purpose of  a shareholder's  Appraisal
Rights  under the Sections,  "fair value" means  the value of  the shares of DMI
Common Stock immediately before the Effective Date and "interest" means interest
commencing five days after the  Effective Date up to  and including the date  of
payment  at the rate of 5% per annum  (the rate provided under Minnesota law for
interest on verdicts and judgments).
 
                                       20
<PAGE>
    DMI may withhold such remittance with respect to shares of DMI Common  Stock
for  which the  shareholder demanding  payment (or  person on  whose behalf such
shareholder acts) was not the beneficial owner on December 8, 1995, the date  of
the  first public announcement  of the Merger  (the "Public Announcement Date").
Following the Effective Date, DMI shall  mail to such shareholder the  materials
described  in the preceding paragraph, a statement of the reason for withholding
the remittance, and an  offer to pay  the amount listed  in the materials,  upon
receipt   of  such  shareholder's  agreement  to  accept  that  amount  in  full
satisfaction. If such shareholder believes that DMI's offer is for less than the
fair value  of the  shares of  DMI Common  Stock, with  interest, if  any,  such
shareholder  must give written notice  to DMI of his or  her own estimate of the
fair value of the shares of DMI Common Stock, with interest, if any, and  demand
payment  of this amount. This demand must be  mailed to DMI within 30 days after
the mailing of DMI's offer. If the shareholder fails to make this demand  within
the  30-day time period, such  shareholder shall be entitled  only to the amount
offered by DMI.
 
    If a shareholder who became a beneficial owner of shares of DMI Common Stock
on or prior to the Public  Announcement Date believes the payment received  from
DMI  is  less than  the  fair value  of  the shares  of  DMI Common  Stock, with
interest, if any, such shareholder must give written notice to DMI of his or her
own estimate of the fair value of the shares of DMI Common Stock, with interest,
if any, within 30 days after the date of DMI's remittance and demand payment  of
the  difference  between  his  or  her estimate  and  DMI's  remittance.  If the
shareholder fails to  give written  notice of such  estimate to  DMI within  the
30-day  time  period,  such shareholder  will  be  entitled only  to  the amount
remitted by DMI.
 
    If DMI  and the  shareholder  (including both  a shareholder  who  purchased
shares  of  DMI  Common  Stock  prior to  the  Public  Announcement  Date  and a
shareholder  who  purchased  shares  of  DMI  Common  Stock  after  the   Public
Announcement  Date who have complied  with their respective demand requirements)
cannot settle the  shareholder's demand within  60 days after  DMI receives  the
shareholder's  estimate of  the fair value  of his  or her shares  of DMI Common
Stock, then DMI shall  file an action  in a court  of competent jurisdiction  in
Hennepin  County, Minnesota, requesting that the  court determine the fair value
of DMI Common Stock  with interest, if any.  All shareholders whose demands  are
not  settled  within  the applicable  60-day  settlement periods  shall  be made
parties to this proceeding.
 
    After notice to the  shareholder, the court  shall institute proceedings  to
determine  the  fair value  of the  shares of  DMI Common  Stock. The  court may
appoint one  or  more  persons  as  appraisers  to  receive  evidence  and  make
recommendations  to  the  court.  Dissenting shareholders  will  be  entitled to
discovery on the  same basis as  any other party  to a civil  action. The  court
shall  determine the fair value  of the shares of  DMI Common Stock, taking into
account any and all factors the court finds relevant, computed by any method  or
combination  of methods that the court, in  its discretion, sees fit to use. The
fair value of  the shares  of DMI  Common Stock as  determined by  the court  is
binding  on all shareholders. If the court determines that the fair value of the
shares of DMI Common Stock is in excess  of DMI's estimate of the fair value  of
the shares of DMI Common Stock, then the court will enter a judgment in favor of
the  dissenting shareholders in an  amount by which the  value determined by the
court exceeds DMI's estimated value, plus interest.
 
    Costs of the court proceeding shall be determined by the court and  assessed
against  DMI, except  that part or  all of  these costs may  be assessed against
shareholders whose actions in demanding  supplemental payments are found by  the
court to be arbitrary, vexatious or not in good faith.
 
    If  the court finds that DMI did not substantially comply with the Sections,
the court may assess the fees and  expenses, if any, of attorneys or experts  as
the  court  deems equitable  against DMI.  Such  fees and  expenses may  also be
assessed against  any  party  if the  court  finds  that such  party  has  acted
arbitrarily,  vexatiously  or  not in  good  faith  with respect  to  the rights
provided by the Sections. In addition,  the court may award, in its  discretion,
fees and expenses to attorneys for the dissenting shareholders out of the amount
awarded to such shareholders.

    On December 7, 1995, the day immediately prior to the public announcement of
the agreement between DMI and Newco, the closing bid price for the Common  Stock
was  $.03. On  March 25, 1996,  the closing bid  price for the  Common Stock was
$.020.
 
    Based on  the nominal  trading in  DMI Common  Stock, the  Company does  not
believe  that the market price  accurately reflects the price  of the shares for
more than a few shares traded in a single transaction. The last sale transaction
known to the  Company occurred on  February 1,  1996, and involved  the sale  of
17,500  shares of  its Common  Stock at a  price of  $.020 per  share. The Board
believes, based on the  very small volume  of trading in  the DMI Common  Stock,
that  the historical trading prices are not representative of the selling prices
which could be expected for sale of a large number of shares of DMI Common Stock
and expects that  the anticipated selling  price for a  large number of  shares,
independent  of a transaction such  as the Merger, would  be much lower than the
historical prices.
 
    DMI has never paid dividends on the Common Stock.

    The  Articles of Incorporation of DMI, as amended, authorize the issuance of
50,000,000 shares of Common Stock, $.15 par value per share, of which 32,533,460
shares were issued and outstanding as of March 25, 1996.
 
    The holders of Common Stock currently  are entitled to receive ratably  such
dividends  as may  be declared by  the Board  of Directors out  of funds legally
available therefor. No cash dividends have  been paid on the Common Stock  since
the  Company's  inception.  On any  liquidation  of  DMI, after  payment  of all
indebtedness, the assets of DMI will be  distributed pro rata to the holders  of
the  Common Stock. If the shareholders of  DMI approve the Merger Agreement, DMI
Minority Shareholders will  no longer have  such rights, but  only the right  to
receive  $.040 in cash (approximately $.013 in  the case of NCS). Holders of the
Common Stock have no  preemptive rights and  are entitled to  one vote for  each
share held on each matter submitted to a vote of shareholders. Cumulative voting
for  the election of directors is not permitted.  At March 25, 1996, DMI had 581
shareholders of record.

    DHT, a  publicly  traded  company (NASDAQ  OTC:  DHTI),  develops,  markets,

industry. DHT currently derives its revenues from application software  licenses
(34%),  software support  and maintenance  (49%), and  computer system equipment
sales and support (17%).
 
    Newco, which is 100% owned by DHT, was organized for purposes of the  Merger
and has not conducted any business since its incorporation.

                                    EXPERTS
 
    The financial statements appearing in the Annual Report on Form 10-K for the
year  ended March 31, 1995  have been audited by  Ernst & Young LLP, independent

herein by  reference.  Such  financial statements  are  incorporated  herein  by

                             SHAREHOLDER PROPOSALS
 
    If  the Merger is not approved, it is  expected that the Common Stock of DMI
will continue to be  registered under Section 12(g)  of the Securities  Exchange
Act of 1934. The rules of the Securities Exchange Commission permit shareholders
of  a public company, after  timely notice to the  Company, to present proposals
for shareholder action in the Company's proxy statement where such proposals are
consistent with applicable law, pertain  to matters appropriate for  shareholder
action  and are not  properly omitted by  company action in  accordance with the
proxy rules. If the Merger is not consummated, DMI expects that its next  Annual
Meeting  of  Shareholders  will be  held  on or  about  May 15,  1997  and proxy
materials in connection with such meeting will  be mailed on or about April  15,
1997.  If  the  Merger is  not  consummated, shareholder  proposals  prepared in
accordance with the proxy rules  must be received by  DMI on or before  December
16, 1996.

       assets  or  liabilities,  or  in   the  business  or  condition  of   the
       Corporation,  financial or otherwise, or the  result of operations of the
       Corporation, whether as a result of any legislative or regulatory change,

       factor or condition exists or, to the Corporation's knowledge and belief,

    3.1(h), none of the  accounts receivable of the  Corporation are subject  to
    any  stated claim  of offset,  recoupment, setoff  or counterclaim,  and the
    Corporation has no knowledge  of any facts or  circumstances giving rise  to

    account receivable is contingent upon the performance by the Corporation  of
    any obligation or contract. Except as
 
                                      A-7

    receivables or any  part thereof,  no agreement for  deduction, free  goods,
    discount  or other deferred price has been  made with respect to any of such

        (k)  TITLE AND RELATED MATTERS.   Schedule 3.1(k) is a true and  correct
    listing  of all categories and  the net book value  of all tangible property
    (real and personal)  owned or leased  by the Corporation  which are not  set
    forth  on the Financial Statements. The  Corporation has good and marketable
    title to all of the assets free and clear of all mortgages, liens,  pledges,
    charges  and  encumbrances,  easements, liabilities,  or  any  other adverse
    claims of  every kind  or  character, except  as  so indicated  on  Schedule
    3.1(k).  All of the assets necessary  for the operation of the Corporation's
    business, including real and personal  property and leasehold interests,  of
    the Corporation are in good and satisfactory working condition.
 
        (l)    PATENTS AND  TRADEMARKS.   Schedule  3.1(l)  contains a  true and
    correct list  of all  registered patents,  patent applications,  trademarks,
    trade  names, copyrights, intellectual properties  or service marks owned by
    or registered in the name of  the Corporation. Furthermore, except as  shown
    on  Schedule  3.1(l), there  are  no material  unregistered  patents, patent
    applications, trademarks, tradenames, copyrights, intellectual properties or
    servicemarks owned by the Corporation.  Except as shown on Schedule  3.1(l),
    there  are no outstanding claims, liens, encumbrances, options, licenses, or
    agreements of any  kind relating to  the foregoing, nor  is the  Corporation
    bound  by or party to  any options, licenses or  agreements of any kind with
    respect to the patents,  trademarks, service marks, tradenames,  copyrights,
    trade  secrets, licenses,  information, proprietary rights  and processes of
    any  other  person  or  entity.  To  its  best  knowledge  and  belief,  the
    Corporation  has sufficient  title and  ownership of  all patents, licenses,
    trademarks, servicemarks, trade names, copyrights to conduct its business as
    now operated without  any conflict  with or  infringement of  the rights  of
    others.  To the knowledge and belief of the Corporation, the Corporation has
    not infringed or violated in any way any valid patent, trademark, trade name
    or copyright of others, nor has  the Corporation received any notice,  claim
    or protest respecting any such violation or infringement. The Corporation is
    not  aware  that  any  of  its employees  is  obligated  under  any contract
    (including licenses,  covenants,  or commitments  of  any nature)  or  other
    agreement,  or subject  to any  judgment, decree  or order  of any  court or
    administrative agency, that would interfere with the use of such  employee's
    best  efforts  to promote  the interests  of the  Corporation or  that would
    conflict with the Corporation's business as currently conducted. Neither the
    execution nor  delivery  of this  Agreement,  nor  the carrying  on  of  the
    Corporation's  business by the employees of the Corporation, nor the conduct
    of  the  Corporation's  business  as  currently  conducted,  will,  to   the
    Corporation's  knowledge, conflict with or result  in a breach of the terms,
    conditions or provisions of,  or constitute a  default under, any  contract,
    covenant  or instrument under which any  of such employees is now obligated.
    The Corporation does not believe it is  or will be necessary to utilize  any
    inventions  of any of its employees (or people it currently intends to hire)
    made prior to their employment by the Corporation.
 
        (m)   TAX  MATTERS.    Except  as set  forth  on  Schedule  3.1(m),  the
    Corporation has filed or caused to be filed, within the times and within the
    manner  prescribed by law, all Federal, state, local and foreign tax returns
    and reports  heretofore required  to be  filed  by it,  and has  no  current
    extensions  for the  filing of  any such  returns or  reports, or delinquent
    liabilities. To the  Corporation's best knowledge  and belief, such  returns
    and  reports reflect accurately all tax liability of the Corporation for the
    periods covered  thereby.  All Federal,  state,  local and  foreign  income,
    profits,  franchise,  sales,  use,  occupancy, excise  and  other  taxes and
    assessments (including interest and penalties) payable by, or due from,  the
    Corporation  (including for this purpose  any subsidiary of the Corporation,
    for such taxable period  or periods in which  such former subsidiary was  an
    affiliated  group as defined in Section 1504(a) of the Internal Revenue Code
    of 1986, as amended, of which the  Corporation was a member) has been  fully
    paid  or  adequately  disclosed and  fully  provided  for in  the  books and
    financial statements of the Corporation. No examination of any tax return of
    the Corporation is currently in progress  or has been noticed except as  set
    forth  on Schedule  3.1(m). There are  no outstanding  agreements or waivers
    extending the statutory period of limitation applicable to any tax return of
    the Corporation.

       course of business.
 
           (4)   For  the  purposes  of  subsections  (2)  and  (3)  above,  all
       indebtedness,  liabilities,   agreements,  understandings,   instruments,
       contracts,  and proposed transactions involving the same person or entity
       (including persons or entities the Corporation has reason to believe  are
       affiliated  therewith) shall be aggregated for the purpose of meeting the
       individual minimum dollar amounts of such subsections.
 
           (5) The Corporation is not a  party to any indenture, loan or  credit
       agreement or any lease or other agreement or instrument or subject to any
       charter  or corporate restriction which has  a material adverse effect on
       the Corporation or limits or restricts the ability of the Corporation  to

    and  belief,  the  subject  of  any  investigation  or  proceeding  by   any
    governmental  body relating to its business.  The Corporation is not subject
    to, nor  in  default  of, any  indictment,  order  or award  of  any  court,
    arbitrator  or  governmental  body,  domestic or  foreign,  relating  to its
    business.

                                INDEMNIFICATION
 
    6.1  INDEMNIFICATION.
 
        (a)  Subject to subsection (d) below, NCS shall indemnify Newco and hold
    it harmless  against  any loss,  liability,  damage, deficiency  or  expense
    (including  reasonable legal expenses and  costs as incurred) (collectively,
    "Losses") which Newco may suffer, sustain or become subject to, directly  or
    indirectly, as a result of or in connection with the breach or inaccuracy by
    NCS  of its representations  or warranties contained in  Section 3.2 of this
    Agreement. With  respect  to  claims  for  breaches  of  representations  or
    warranties  contained in this Agreement, or  in any agreement relating to or
    contemplated hereby,  NCS  shall  be  liable  with  respect  to  any  Losses
    regardless  of when finally ascertained, provided written notice is given by
    Newco pursuant to  Paragraph (d) below.  Notwithstanding the foregoing,  the
    representations  and warranties of NCS and the indemnification obligation of
    NCS contained in this  Agreement shall terminate and  expire six (6)  months
    from  the Closing Date. Furthermore, the  maximum aggregate amount which NCS
    may be liable for  pursuant to its  indemnification obligation contained  in
    this Agreement shall be $355,000.
 
        (b)   Subject  to  subsection  (d)  below,  Newco  shall  indemnify  the
    Corporation and NCS and hold them harmless against any Losses which they may
    suffer, sustain or become subject to, as the result of or in connection with
    (i) the breach by Newco of any representation or warranty of Newco contained
    in this Agreement, or in any  agreement relating to or contemplated  hereby,
    or  (ii) the breach by Newco of any covenant or agreement of Newco contained
    in this Agreement or  in any agreement relating  to or contemplated  hereby.
    With  respect  to  claims  for  breaches  of  representation  and warranties
    contained in this Agreement, or in any agreement relating to or contemplated
    hereby, Newco will be liable with respect to any Losses, regardless of  when
    finally  ascertained, if written notice of a  claim for such breach is given
    by Corporation or NCS to Newco pursuant to paragraph (c) below.
 
        (c) Subject to subsection (d) below,  Newco and DHT shall indemnify  NCS
    and  hold it harmless against any  Losses (including without limitation, any
    cost or expenses associated with
 
                                      A-19
<PAGE>
    performance of standby  support obligations) which  it may suffer,  sustain,
    incur or become subject to, as a result of or in connection with, any claim,
    demand  or other requirement made or asserted against NCS from and after the
    Closing Date,  under, pursuant  to or  arising out  of any  standby  support
    agreement  or other  similar agreement between  NCS and any  customer of the
    Corporation, as  listed on  Schedule 5.2(d)  hereto, pursuant  to which  NCS
    guarantees,  agrees to  provide for  or agrees to  perform in  place of, the
    performance   of   the   Corporation,   (collectively,   "Standby    Support
    Agreements"). Notwithstanding subsection (d) below, NCS shall be entitled at
    its  option, but not  obligated, to perform the  requirements of any Standby
    Support Agreement,  upon customer  demand until  and unless  Newco  provides
    performance  which  is  satisfactory to  the  customer as  confirmed  by the
    customer in  writing,  and all  expense  of  such performance,  if  any,  in
    addition  to any other Losses resulting from such claim, shall be subject to
    the indemnity provided in this Section 6.1(c).
 
        (d) Any party making a claim for indemnification under this Section  6.1
    (an  "Indemnitee") shall notify the  indemnifying party (an "Indemnitor") of
    the claim  in writing  promptly  after discovering  the claim  or  receiving
    written  notice of a claim against it  (if by a third party), describing the
    claim, the  amount  thereof  (if  known and  quantifiable),  and  the  basis
    thereof.  Any claim for indemnification under this Section 6.1 to the extent
    such claim can  be reasonably quantified,  must be for  a minimum amount  of
    $15,000 or when the amount of such claim is aggregated with other claims for
    indemnification brought under this Section 6.1 equals or exceeds $15,000. An
    Indemnitor shall be entitled to participate in the defense of such action at
    its  expense, and at its option (subject to the limitations set forth below)
    shall be entitled to assume control of such defense with reputable  counsel;
    provided,  that prior to  Indemnitor assuming control of  such defense it or
    they shall first verify  to the Indemnitee in  writing that such  Indemnitor
    shall  be fully responsible for such claim and that it will provide the full
    indemnification required hereunder to Indemnitee with respect to such claim,
    including payment thereof and performance thereunder; and provided  further,
    that:
 
           (i) The Indemnitee shall be entitled to participate in the defense of
       such claim and to employ counsel of its choice for such purpose, the fees
       and expenses of such separate counsel which shall be borne by Indemnitee.
       Notwithstanding  the foregoing,  the fees  and expenses  of such separate
       counsel incurred prior to the  date the Indemnitor's counsel  effectively
       assumes control of such defense shall be borne by the Indemnitor; and
 
           (ii)  The  Indemnitee shall  be entitled  to  assume control  of such
       defense and shall bear the fees  and expenses of counsel retained by  the
       Indemnitor  if, upon petition by  Indemnitee, the appropriate court rules
       that the  Indemnitor failed  or  is failing  to vigorously  prosecute  or
       defend such claim; and
 
          (iii)  The Indemnitor shall not be  entitled to control the defense of
       any claim to the extent that  the claim seeks an injunction or  equitable
       relief   against  Indemnitee  which,   if  successful,  could  materially
       interfere with the business  of the Indemnitee.  If the Indemnitor,  with
       the  consent of  the Indemnitee,  shall control  the defense  of any such
       claim, the  Indemnitor shall  obtain  the prior  written consent  of  the
       Indemnitee  (which shall  not be  unreasonably withheld)  before entering
       into any  settlement of  a claim  or  ceasing to  defend such  claim,  if
       pursuant to or as a result of such settlement or cessation, injunction or
       other equitable relief will be imposed against the Indemnitee.
 
          (iv) If the claim is the result of an asserted breach of any warranty,
       representation or covenant, and such claim is material, then the costs of
       defense of such claim shall be borne by the Indemnitor on a current basis
       if so requested by Indemnitee.

               OPINION OF JOHN G. KINNARD & COMPANY, INCORPORATED
 
March 28, 1996
 
Board of Directors
Dimensional Medicine, Inc.
10901 Bren Road East
Minnetonka, Minnesota 55343
 
Dear Directors:
 
    You have requested our opinion as to the fairness, from a financial point of
view,  to the minority holders of the common stock of Dimensional Medicine, Inc.
("DMI" or the "Company") other than National Computer Systems, Inc. ("NCS") (the
"Minority Shareholders") of the  consideration which is proposed  to be paid  to
such  holders pursuant  to a  Merger Agreement  (the "Merger  Agreement") by and
among DMI, Dynamic Healthcare Technologies, Inc. ("DHT"), DMI Acquisition Corp.,
a wholly owned  subsidiary of DHT  ("Newco"), and NCS,  the Company's  principal
shareholder,  pursuant to which the  Company will be merged  with and into Newco
(the "Merger"). Pursuant to the  Merger Agreement, the total outstanding  shares
of  common  stock  of  DMI will  be  converted  into the  right  to  receive, in
aggregate, $550,000  cash; of  this $550,000  consideration, each  share of  DMI
common  stock held by Minority Shareholders will  be converted into the right to
receive $0.040 cash  and each  share of  DMI common stock  held by  NCS will  be
converted into the right to receive approximately $0.013 cash.
 
    John  G.  Kinnard  &  Company,  Incorporated  ("Kinnard"),  as  part  of its
investment banking activities, is accustomed  to valuing virtually all types  of
securities  and to  advising the  directors, officers  and shareholders  of both
public and  private companies  with respect  to  the fairness  of the  terms  of
investments,  mergers and acquisitions.  Kinnard is independent  with respect to
the Merger and did not  act as financial advisor to  DMI regarding the terms  of
the Merger.
 
    In  connection with this opinion we  have reviewed and analyzed, among other
things, certain historical and projected  financial information on the  Company;
visited  the corporate offices of the  Company; and held discussions with senior
management and the  directors of  DMI regarding  the past  and current  business
operations,  financial  condition,  and  future prospects  for  the  Company. We
reviewed an executed copy of the Merger Agreement dated February 5, 1996 and the
Proxy Statement  dated  March  28,  1996 relating  to  the  special  meeting  of
shareholders of DMI.
 
    We  reviewed the historical  reported market prices  and trading activity of
the common stock of DMI. We  compared financial and stock market information  on
DMI  to  similar information  for  certain publicly  traded  companies providing
health care  information  and  imaging  products. We  reviewed,  to  the  extent
publicly  available,  the  terms  of selected  relevant  merger  and acquisition
transactions; analyzed the general economic  outlook of companies in the  health
care  information technology industry; and  performed other studies and analyses
as we considered appropriate.
 
    In preparing our opinion,  we relied upon the  accuracy and completeness  of
all  information provided or otherwise  made available to us  by DMI, and we did
not independently  verify  such information.  We  did not  make  an  independent
appraisal  of the assets of  DMI and we do not  express an opinion regarding the
liquidation value of the Company.
 
                                      B-1
<PAGE>
    Based upon the foregoing, and other matters that we consider relevant, it is
our opinion that,  as of the  date hereof, both  the aggregate consideration  of
$550,000  cash to be received  for all outstanding common  shares of DMI and the
per  share  consideration  of  $0.040  cash  to  be  received  by  the  Minority
Shareholders in connection with the Merger are fair to the Minority Shareholders
from a financial point of view.
 
                                          Very truly yours,
 
                                          /s/ John G. Kinnard & Company,
                                          Incorporated
 
                                          JOHN G. KINNARD & COMPANY,

              PROVISIONS OF THE MINNESOTA BUSINESS CORPORATION ACT
                 RELATING TO RIGHTS OF DISSENTING SHAREHOLDERS
 
302A.471. RIGHTS OF DISSENTING SHAREHOLDERS
 
    Subdivision 1.  ACTIONS CREATING RIGHTS.  A shareholder of a corporation may
dissent  from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:
 
    (a) An amendment of the articles  that materially and adversely affects  the
rights or preferences of the shares of the dissenting shareholder in that it:
 
        (1) alters or abolishes a preferential right of the shares;
 
        (2)  creates, alters, or abolishes a  right in respect of the redemption
    of the  shares, including  a provision  respecting a  sinking fund  for  the
    redemption or repurchase of the shares;
 
        (3)  alters or abolishes a preemptive right  of the holder of the shares
    to acquire  shares, securities  other  than shares,  or rights  to  purchase
    shares or securities other than shares;
 
        (4)  excludes or limits the right of  a shareholder to vote on a matter,
    or to cumulate votes, except as the right may be excluded or limited through
    the authorization or issuance of securities  of an existing or new class  or
    series  with similar or different voting rights; except that an amendment to
    the articles of  an issuing  public corporation that  provides that  section
    302A.671 does not apply to a control share acquisition does not give rise to
    the right to obtain payment under this section;
 
    (b)  A sale, lease,  transfer, or other disposition  of all or substantially
all of  the  property  and  assets  of the  corporation,  but  not  including  a
transaction   permitted  without  shareholder   approval  in  section  302A.661,
subdivision 1, or a  disposition in dissolution  described in section  302A.725,
subdivision  2,  or  a  disposition  pursuant  to an  order  of  a  court,  or a
disposition for cash on terms requiring that all or substantially all of the net
proceeds of disposition be  distributed to the  shareholders in accordance  with
their respective interests within one year after the date of disposition;
 
    (c)  A plan of merger, whether under  this chapter or under chapter 322B, to
which the corporation is a party, except as provided in subdivision 3;
 
    (d) A plan of exchange, whether under this chapter or under chapter 322B, to
which the  corporation  is a  party  as the  corporation  whose shares  will  be
acquired  by the  acquiring corporation,  if the  shares of  the shareholder are
entitled to be voted on the plan; or
 
    (e) Any other  corporate action taken  pursuant to a  shareholder vote  with
respect to which the articles, the bylaws, or a resolution approved by the board
directs that dissenting shareholders may obtain payment for their shares.
 
    Subd. 2.  BENEFICIAL OWNERS.  (a) A shareholder shall not assert dissenters'
rights  as  to  less than  all  of the  shares  registered  in the  name  of the
shareholder, unless the shareholder dissents with respect to all the shares that
are beneficially  owned by  another person  but registered  in the  name of  the
shareholder and discloses the name and address of each beneficial owner on whose
behalf  the shareholder  dissents. In  that event,  the rights  of the dissenter
shall be determined as if the shares  as to which the shareholder has  dissented
and the other shares were registered in the names of different shareholders.
 
    (b)  The beneficial owner  of shares who  is not the  shareholder may assert
dissenters' rights  with respect  to shares  held on  behalf of  the  beneficial
owner,  and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or  before the assertion of the  rights a written consent of  the
shareholder.
 
                                      C-1
<PAGE>
    Subd.  3.   RIGHTS NOT  TO APPLY.   Unless  the articles,  the bylaws,  or a
resolution approved by the board otherwise provide, the right to obtain  payment
under  this section does not apply to a shareholder of the surviving corporation
in a merger, if the  shares of the shareholder are  not entitled to be voted  on
the merger.
 
    Subd.  4.  OTHER RIGHTS.  The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside  or
rescinded,  except when  the corporate action  is fraudulent with  regard to the
complaining shareholder or the corporation.
 
302A.473. PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS
 
    Subdivision 1.  DEFINITIONS.   (a) For purposes  of this section, the  terms
defined in this subdivision have the meanings given them.
 
    (b)  "Corporation" means the issuer of the shares held by a dissenter before
the corporate  action referred  to in  section 302A.471,  subdivision 1  or  the
successor by merger of that issuer.
 
    (c)  "Fair  value  of  the  shares"  means the  value  of  the  shares  of a
corporation immediately  before  the  effective date  of  the  corporate  action
referred to in section 302A.471, subdivision 1.
 
    (d)  "Interest" means interest commencing five days after the effective date
of the corporate action  referred to in section  302A.471, subdivision 1, up  to
and  including the date of  payment, calculated at the  rate provided in section
549.09 for interest on verdicts and judgments.
 
    Subd. 2.  NOTICE OF ACTION.  If a corporation calls a shareholder meeting at
which any action  described in section  302A.471, subdivision 1  is to be  voted
upon,  the notice of the  meeting shall inform each  shareholder of the right to
dissent and shall  include a copy  of section  302A.471 and this  section and  a
brief description of the procedure to be followed under these sections.
 
    Subd. 3.  NOTICE OF DISSENT.  If the proposed action must be approved by the
shareholders,  a shareholder who wishes to exercise dissenters' rights must file
with the corporation before the vote on the proposed action a written notice  of
intent  to demand the fair value of the shares owned by the shareholder and must
not vote the shares in favor of the proposed action.
 
    Subd. 4.  NOTICE OF  PROCEDURE; DEPOSIT OF SHARES.   (a) After the  proposed
action  has been approved by the board  and, if necessary, the shareholders, the
corporation shall send to all shareholders who have complied with subdivision  3
and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:
 
        (1)  The  address to  which  a demand  for  payment and  certificates of
    certificated shares must be sent in order to obtain payment and the date  by
    which they must be received;
 
        (2)  Any  restrictions on  transfer of  uncertificated shares  that will
    apply after the demand for payment is received;
 
        (3) A form to be used to  certify the date on which the shareholder,  or
    the  beneficial owner on whose behalf the shareholder dissents, acquired the
    shares or an interest in them and to demand payment; and
 
        (4) A copy of section 302A.471 and this section and a brief  description
    of the procedures to be followed under these sections.
 
        (b)  In order  to receive  the fair  value of  the shares,  a dissenting
    shareholder must demand  payment and deposit  certificated shares or  comply
    with  any restrictions on  transfer of uncertificated  shares within 30 days
    after the notice  required by  paragraph (a)  was given,  but the  dissenter
    retains  all other rights  of a shareholder until  the proposed action takes
    effect.
 
                                      C-2
<PAGE>
    Subd. 5.  PAYMENT; RETURN OF SHARES.   (a) After the corporate action  takes
effect,  or after the corporation receives a valid demand for payment, whichever
is later, the  corporation shall remit  to each dissenting  shareholder who  has
complied  with subdivisions 3 and  4 the amount the  corporation estimates to be
the fair value of the shares, plus interest, accompanied by:
 
        (1) The corporation's closing balance sheet and statement of income  for
    a  fiscal year ending not  more than 16 months  before the effective date of
    the corporate action, together with  the latest available interim  financial
    statements;
 
        (2) An estimate by the corporation of the fair value of the shares and a
    brief description of the method used to reach the estimate; and
 
        (3) A copy of section 302A.471 and this section, and a brief description
    of the procedure to be followed in demanding supplemental payment.
 
    (b)  The corporation may withhold the  remittance described in paragraph (a)
from a person who was  not a shareholder on the  date the action dissented  from
was first announced to the public or who is dissenting on behalf of a person who
was  not a  beneficial owner on  that date.  If the dissenter  has complied with
subdivisions 3  and  4, the  corporation  shall  forward to  the  dissenter  the
materials  described in paragraph (a), a statement of the reason for withholding
the remittance, and an offer  to pay to the dissenter  the amount listed in  the
materials  if the dissenter  agrees to accept that  amount in full satisfaction.
The dissenter may  decline the  offer and  demand payment  under subdivision  6.
Failure  to do  so entitles  the dissenter  only to  the amount  offered. If the
dissenter makes demand, subdivisions 7 and 8 apply.
 
    (c) If the corporation fails to remit payment within 60 days of the  deposit
of  certificates or  the imposition  of transfer  restrictions on uncertificated
shares, it  shall return  all  deposited certificates  and cancel  all  transfer
restrictions. However, the corporation may again give notice under subdivision 4
and require deposit or restrict transfer at a later time.
 
    Subd.  6.  SUPPLEMENTAL PAYMENT;  DEMAND.  If a  dissenter believes that the
amount remitted under subdivision 5  is less than the  fair value of the  shares
plus  interest, the dissenter may give written  notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest,  within
30  days after  the corporation  mails the  remittance under  subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.
 
    Subd. 7.   PETITION; DETERMINATION.   If the corporation  receives a  demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay  to the dissenter  the amount demanded  or agreed to  by the dissenter after
discussion with the corporation or file in court a petition requesting that  the
court  determine the fair value of the shares, plus interest. The petition shall
be filed in  the county in  which the  registered office of  the corporation  is
located,  except that  a surviving  foreign corporation  that receives  a demand
relating to the  shares of  a constituent  domestic corporation  shall file  the
petition  in the county in this state in which the last registered office of the
constituent corporation  was located.  The petition  shall name  as parties  all
dissenters  who  have demanded  payment  under subdivision  6  and who  have not
reached agreement with the corporation. The corporation shall, after filing  the
petition,  serve all parties with  a summons and copy  of the petition under the
rules of civil procedure. Nonresidents of this state may be served by registered
or certified mail  or by  publication as provided  by law.  Except as  otherwise
provided,   the  rules  of  civil  procedure   apply  to  this  proceeding.  The
jurisdiction of  the court  is  plenary and  exclusive.  The court  may  appoint
appraisers,  with  powers and  authorities the  court  deems proper,  to receive
evidence on and recommend the amount of the fair value of the shares. The  court
shall  determine whether the shareholder or  shareholders in question have fully
complied with the  requirements of this  section, and shall  determine the  fair
value  of the shares,  taking into account  any and all  factors the court finds
relevant, computed by any  method or combination of  methods that the court,  in
its  discretion, see fit to use, whether or  not used by the corporation or by a
dissenter.   The    fair    value   of    the    shares   as    determined    by
 
                                      C-3
<PAGE>
the  court  is binding  on all  shareholders, wherever  located. A  dissenter is
entitled to judgment  in cash  for the  amount by which  the fair  value of  the
shares  as determined by the  court, plus interest, exceeds  the amount, if any,
remitted under subdivision 5, but shall not be liable to the corporation for the
amount, if any, by  which the amount,  if any, remitted  to the dissenter  under
subdivision  5 exceeds the fair value of  the shares as determined by the court,
plus interest.
 
    Subd. 8.  COSTS; FEES;  EXPENSES.  (a) The  court shall determine the  costs
and  expenses  of a  proceeding under  subdivision  7, including  the reasonable
expenses and compensation of  any appraisers appointed by  the court, and  shall
assess  those costs and expenses against  the corporation, except that the court
may assess part or  all of those  costs and expenses  against a dissenter  whose
action  in  demanding payment  under  subdivision 6  is  found to  be arbitrary,
vexatious, or not in good faith.
 
    (b)  If  the  court  finds  that  the  corporation  has  failed  to   comply
substantially  with this section, the court may  assess all fees and expenses of
any experts or attorneys as the  court deems equitable. These fees and  expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not  in good  faith in bringing  the proceeding, and  may be awarded  to a party
injured by those actions.
 
    (c) The court may award, in its discretion, fees and expenses to an attorney
for the dissenters out of the amount awarded to the dissenters, if any.
