    THE  FOLLOWING SUMMARY IS  QUALIFIED IN ITS  ENTIRETY AND SHOULD  BE READ IN
CONJUNCTION WITH  THE MORE  DETAILED INFORMATION  AND FINANCIAL  STATEMENTS  AND
NOTES  THERETO  APPEARING  ELSEWHERE IN  THIS  PROSPECTUS. FOR  A  DISCUSSION OF

                                  THE COMPANY
 
    CIMA  is a  drug delivery company  focused primarily on  the development and
manufacture  of  pharmaceutical  products   based  upon  its  patented   OraSolv
technology.    OraSolv   is    an   oral    dosage   formulation   incorporating
microencapsulated active drug ingredients into a tablet which dissolves  quickly
in  the mouth without chewing or water  and which effectively masks the taste of
the medication being delivered. OraSolv's fast-dissolving capability may  enable
patients  in certain age groups or those with a variety of conditions that limit
their ability to swallow  conventional tablets to receive  medication in a  more
convenient  oral  dosage  form.  The  Company  believes  that  OraSolv  is  more
convenient than traditional  tablet-based oral  dosages as it  does not  require
water  to be  ingested, thereby  enabling immediate  medication at  the onset of
symptoms. In addition, OraSolv can provide more accurate administration of doses
than liquid or suspension formulations as no measuring is required. The  Company
believes OraSolv's ability to be easily ingested by patients will foster greater
patient compliance, thereby improving therapeutic outcomes and reducing costs in
the healthcare system.
 
    CIMA's  business  focus  has  evolved  over  the  last  several  years. From
inception  until  1992,  the  Company  focused  on  the  development  of  liquid
effervescent  products  and  technologies.  In 1993,  the  U.S.  patent covering
OraSolv was issued and the  Company, perceiving greater commercial  opportunity,
shifted  its  focus to  the  development of  OraSolv  products. CIMA  intends to
commercialize the OraSolv technology through collaborations with  pharmaceutical
and   other  healthcare  companies  by   developing  and  manufacturing  OraSolv
formulations of its collaborators'  pharmaceutical products. Since the  issuance
of the OraSolv patent in 1993, the Company has:
 
    - Completed  construction of a 75,000  square foot manufacturing facility in
      Eden Prairie,  Minnesota,  which has  been  registered with  the  FDA  and
      licensed by the State of Minnesota.
 
    - Entered  into a License and Development  Agreement with Glaxo Wellcome plc
      ("Glaxo") to develop an OraSolv version of Glaxo's Zantac.
 
    - Entered into  a License  Agreement and  a Development  and License  Option
      Agreement  with SmithKline Beecham plc ("SmithKline Beecham") to develop a
      series  of   OraSolv  versions   of   SmithKline  Beecham   products   for
      international and domestic distribution.
 
    - Entered  into  agreements  with  three other  potential  partners  for the
      development and manufacture of OraSolv products.
 
    - Entered into  a  License and  Supply  Agreement  with Merck  &  Co.,  Inc.
      ("Merck")  to  provide an  AutoLution (a  liquid effervescent)  version of
      Merck's Pepcid AC.
 
    - Added key scientific, technical and management personnel.
 
    The Company's corporate partnerships enable  it to focus on the  development
and  manufacture of OraSolv  versions of its  partners' products, while allowing
its partners to focus on the marketing and distribution of OraSolv formulations.
Generally, the Company will be responsible for optimizing the taste-masking  and
microencapsulation  of  the active  drug  ingredient, manufacturing  the OraSolv
tablets containing the active drug,  packaging, labeling and performing  quality
assurance on the finished product, and shipping the product to its partners. The
Company's  corporate  partners  will  be  responsible  for  marketing,  sale and
distribution of the  OraSolv product to  consumers or healthcare  professionals.
Generally,  corporate partners will  also be responsible  for the collection and
submission of required clinical data, and for the management of required federal
or international regulatory approvals of collaborative products.
 
    The Company's goal is  to have its OraSolv  technology incorporated into  as
many  pharmaceutical  products as  possible with  an emphasis  on pharmaceutical
products which command a large market share or are in large market segments. The
Company has developed a  strategic plan to accomplish  this goal. The  Company's
primary  strategies are to: (i) establish collaborations with pharmaceutical and
other healthcare companies; (ii) focus  initially on OTC products; (iii)  pursue
OTC  switch  and  prescription  drugs;  (iv)  expand  its  intellectual property
position; (v) retain the manufacturing rights  to the products it develops;  and
(vi) retain ownership of products developed.

                                  RISK FACTORS
 
    IN  ADDITION  TO THE  OTHER INFORMATION  CONTAINED  IN THIS  PROSPECTUS, THE
FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING THE  COMPANY
AND ITS BUSINESS BEFORE PURCHASING SHARES OF THE COMMON STOCK OFFERED HEREBY.
 
NO REVENUES FROM ORASOLV SALES
 
    The  Company's  ability  to generate  revenues  will be  dependent  upon its
ability to enter into and perform under collaborative agreements to develop  and
manufacture  OraSolv  products  to  be  marketed  by  pharmaceutical  and  other
healthcare  companies  and  upon  the  successful  commercialization  of   these
products.  To date no commercial  sales of OraSolv products  have been made, and
the Company  has  not derived  any  revenues  from sales  of  OraSolv  products.
Further, the Company does not expect to derive any such revenues until 1997.
 
HISTORY OF OPERATING LOSSES; UNCERTAINTY OF FUTURE PROFITABILITY
 
    The Company is a development stage company and must be evaluated in light of
the  uncertainties  and  complications  present for  any  such  company  and, in
particular,  a  company  in  the   pharmaceutical  industry.  The  Company   has
accumulated  net losses from inception in  December 1986 through March 31, 1996,
of approximately  $30,899,000.  Losses  have  resulted  principally  from  costs
incurred  in research  and development  of the  Company's technologies  and from
general and  administrative  costs.  These costs  have  exceeded  the  Company's
revenues,  which have  been derived primarily  from the  manufacturing of liquid
effervescents  and  other  non-OraSolv  products  under  agreements  with  third
parties.  The Company no longer manufactures such products and no longer derives
revenues from their manufacture. The Company expects to continue to incur losses
at least through 1997. Many of the Company's expenditures to date have been non-
recurring costs for  plant, equipment and  product optimization and  validation.
There  can  be  no  assurance,  however, that  the  Company  will  ever generate
substantial revenues or achieve profitability.
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING
 
    The Company currently has cash  reserves sufficient to operate through  June
1996. In the event that the offering does not close or is substantially delayed,
the  Company's ability to continue as a going concern will be severely impaired.
The Company believes that  the net proceeds to  the Company from this  offering,
combined  with its currently available funds and excluding any license fees that
may be received in the  future, will meet its needs  at least through the  first
quarter  of 1997.  Thereafter, or  sooner if  conditions make  it necessary, the
Company may need to raise additional funds through public or private financings,
including equity financings which may  be dilutive to stockholders, and  through
collaborative  arrangements. There can be no  assurance that the Company will be
able to raise additional funds if  its capital resources are exhausted, or  that
funds  will  be available  on  terms attractive  to the  Company  or at  all. If
adequate funds are not available, the  Company may be required to delay,  reduce
the  scope of or eliminate one or  more of its research or development programs,
which would have a material adverse effect on the Company. See "Use of Proceeds"
and "Management's Discussion and Analysis of Financial Condition and Results  of
Operations."
 
DEPENDENCE UPON THIRD PARTIES
 
    The  Company's  strategy is  to enter  into collaborative  arrangements with
pharmaceutical and other healthcare companies to develop OraSolv products to  be
marketed  by the  corporate partners. The  Company's future  ability to generate
revenues is, therefore, dependent upon the Company's ability to develop products
that meet the  requirements of  its corporate  partners and  upon the  marketing
efforts  of  these  corporate  partners.  Although  the  Company  believes these
partners will have an economic  motivation to market these products  vigorously,
the amount and timing of resources to be devoted to marketing are not within the
control  of  the  Company.  These  partners  independently  could  make material
marketing and other commercialization decisions which could adversely affect the
Company's future revenues.  Failure of  these partners to  market the  Company's
products  successfully would  have a  material adverse  effect on  the Company's
financial  condition  and  results  of  operations.  Moreover,  certain  of  the
Company's  products are seasonal in nature and the Company's revenues could vary
materially from one financial period to another
 
                                       5
<PAGE>
depending on which of such products, if  any, are then being marketed. To  date,
the  Company  has experienced  delays in  the  scheduled development  and market
introduction of products  incorporating OraSolv technology,  in part because  of
changes  in product plans by  its corporate partners. There  can be no assurance
that  the  Company  will  be   able  to  enter  into  additional   collaborative
arrangements  in  the  future  or  that  any  current  or  future  collaborative
arrangements will result in successful product commercialization.
 
    The Company is  not currently reliant  on any single  supplier or source  of
supply;  however,  coating  materials  and techniques  used  in  connection with
manufacturing certain OraSolv products may in the future be available only  from
a  single supplier. Although the Company believes that satisfactory alternatives
could be substituted if any such coating materials or techniques were to  become
unavailable,  there  can  be  no  assurance  that  the  Company's  manufacturing
operations would not  be disrupted. Any  such disruption could  have at least  a
temporary  adverse effect  on the Company's  business and  could possibly damage
relations with its corporate partners.
 
NATURE OF COLLABORATIVE ARRANGEMENTS; PRODUCT DEVELOPMENT PROCESS
 
    The Company  typically  begins working  with  its corporate  partners  under
feasibility  study agreements  or option  agreements which  permit CIMA  and its
corporate partners to  develop prototype products  and manufacturing  techniques
for  the product in question but without a substantial contractual commitment by
either side. During this phase of the collaboration, CIMA and its partner  study
issues  of taste masking, bioavailability,  production processes and issues that
may arise  in  the  course  of manufacturing  in  commercial  volumes,  consumer
satisfaction,  and  the  related issues  of  cost, price  and  potential product
volume. Since  no  products  incorporating  OraSolv  technology  have  yet  been
marketed,  many of  these issues  (particularly those  related to  marketing and
consumer preferences) remain commercially  untested and determinations  relative
to these issues are largely subjective. Accordingly, it is difficult to predict,
and  impossible  for  the  Company  to  control,  whether  a  particular product
development program will lead to a  decision by the corporate partner to  market
the  product in question.  Each of the Company's  current development and option
agreements permits its corporate partner to terminate the development program at
the corporate partner's discretion on  relatively short notice. In addition,  in
the  past the Company has experienced  delays and cancellations by its corporate
partners, and there can be  no assurance that it  will not experience delays  or
cancellations in the future. Even though the Company is working with a number of
collaborators  with respect to OraSolv products,  there is no assurance that any
of these collaborators will ultimately market any such products.
 
    The option and development agreements entered into by the Company  generally
provide  for the essential terms (including royalty amounts) to be included in a
subsequent license agreement for full commercialization, but they do not contain
all of the license terms. Even if the product development process is a  success,
there can be no assurance that the parties will agree on the ultimate commercial
terms.  In particular, the costs of manufacturing OraSolv products in commercial
quantities remains subject to some uncertainty, and in the highly cost-sensitive
market for  OTC  products,  there  may  be  instances  in  which  CIMA  and  its
collaborator  have  difficulty agreeing  on  issues of  manufacturing  costs and
supply arrangements for commercialization.
 
    The Company  generally intends  to retain  product manufacturing  rights  in
connection  with its definitive  license agreements. There  can be no assurance,
however, that the Company will retain such rights in every agreement or that any
such rights retained  will be  profitable for the  Company. The  failure by  the
Company  to retain manufacturing rights  under any definitive license agreements
entered into with its corporate partners or an event such as the termination  of
the  Company's manufacturing rights under an agreement with a partner could have
a material adverse effect on the Company's profitability.
 
UNCERTAINTY OF CONSUMER ACCEPTANCE OF ORASOLV PRODUCTS
 
    The Company's OraSolv technology, a fast-dissolving oral tablet,  represents
a  new dosage form for pharmaceutical  products. As a consequence, the Company's
revenues will be dependent upon ultimate consumer acceptance of the OraSolv drug
delivery system as an alternative to conventional oral dosage forms, as well  as
upon  the marketing efforts of its  corporate partners. The Company expects that
OraSolv
 
                                       6
<PAGE>
products will be priced higher  than conventional tablets. The Company  believes
that  initial  consumer  research has  been  encouraging,  but there  can  be no
assurance that commercial market acceptance  for the Company's OraSolv  products
will ever develop or be sustained.
 
COMPETITION; TECHNOLOGICAL RISK
 
    Competition  in  the  areas  of pharmaceutical  products  and  drug delivery
systems is intense.  Several other  companies have developed  or are  developing
novel  technologies for oral drug delivery, and these competing technologies may
prove superior, either generally or in  particular market segments, in terms  of
factors  such as  cost, consumer satisfaction,  or drug  delivery. The Company's
primary competitors in  the business  of developing and  applying drug  delivery
systems   include   companies  which   have  substantially   greater  financial,
technological, marketing, personnel and research and development resources  than
the  Company. The Company's  products will compete  both with products employing
advanced drug delivery systems and  with products in conventional dosage  forms.
New  drugs or future developments in  alternative drug delivery technologies may
provide therapeutic  or cost  advantages to  the Company's  potential  products.
There  can  be no  assurance that  developments  by others  will not  render the
Company's products or technologies noncompetitive or obsolete.
 
PATENTS AND PROPRIETARY RIGHTS
 
    The Company's  success will  depend in  part on  its ability  to obtain  and
maintain  patent protection for its products  and to preserve its trade secrets.
The Company holds  five issued  U.S. patents  (including a  patent covering  the
OraSolv  technology) and two issued non-U.S. patents. The Company also has three
U.S. patent applications  pending and  a number of  foreign patent  applications
pending, including two European Patent Office filings. No assurance can be given
that  the  Company's patent  applications will  be approved  or that  any issued
patents will provide  competitive advantages  for its  products or  will not  be
challenged  or circumvented  by competitors.  The Company  also relies  on trade
secrets and proprietary  know-how which it  seeks to protect,  in part,  through
confidentiality  agreements  with employees,  consultants, partners  and others.
There can be no assurance that these  agreements will not be breached, that  the
Company  will have adequate remedies  for any such breach  or that the Company's
trade secrets will not otherwise become  known or be independently developed  by
competitors.
 
    The  Company  has obtained  a  license to  a  U.S. patent  and corresponding
foreign rights held by a third party, which patent and corresponding rights  may
cover certain OraSolv products. The Company has obtained or may in the future be
required  to obtain licenses from  others with respect to  materials used in the
Company's  products   or  manufacturing   processes,  including   drug   coating
techniques.  There can be no assurance that  such licenses will be obtainable on
commercially reasonable  terms, if  at  all, or  that  any licensed  patents  or
proprietary rights will be valid and enforceable.
 
    The  ability  to commercialize  the Company's  products  will depend  on not
infringing the patents of others. Although the Company is not aware of any claim
of patent infringement  against it,  claims concerning  patents and  proprietary
technologies  determined adversely to the Company  could have a material adverse
effect on the Company's business. In addition, litigation may also be  necessary
to  enforce any patents  issued or licensed  to the Company  or to determine the
scope and validity of third party proprietary rights. There can be no  assurance
that  the Company's issued or licensed patents would be held valid by a court of
competent jurisdiction. Whether or not the outcome of litigation is favorable to
the Company, the  cost of  such litigation and  the diversion  of the  Company's
resources  during such  litigation could have  a material adverse  effect on the
Company.
 
RISK OF MANUFACTURING IN COMMERCIAL QUANTITIES; SINGLE FACILITY
 
    The  Company  has  not  yet  manufactured  OraSolv  products  in  commercial
quantities.  To  achieve  desired  levels of  production,  the  Company  will be
required to  substantially increase  its manufacturing  focus. There  can be  no
assurance  that manufacturing and control problems will not arise as the Company
begins manufacturing  commercial  quantities  at its  new  facility  (which  was
completed  in December 1994) or that manufacturing  volume can be increased in a
timely   manner   to    allow   production   in    sufficient   quantities    to
 
                                       7
<PAGE>
meet  the needs  of the Company's  corporate partners. If  such manufacturing or
control problems  arise or  the Company  is not  able to  successfully  increase
manufacturing  volume in a timely manner  for any reason, the Company's business
could be materially adversely affected.
 
    In addition,  the  Company  currently  has  only  one  facility  capable  of
manufacturing  OraSolv products. In  the event that this  facility is damaged by
natural disaster or otherwise, or the facility becomes incapable of operating at
commercial capacity or at  all due to regulatory  or other reasons, the  Company
would  have no  other means  of producing OraSolv  products, which  would have a
material adverse effect on the Company's  business. In addition, certain of  the
Company's  partners  and  potential  partners have  expressed  concern  that the
Company does not have  alternative facilities to produce  their products in  the
event that the Company's current facility becomes damaged or is otherwise unable
to  produce their products in the volumes  required or at all. Such concerns may
have  an  adverse  effect  on  the  Company's  ability  to  attract   additional
collaborative  partners or  to negotiate  agreements with  potential partners on
terms attractive  to  the  Company.  See "Business  --  Manufacturing"  and  "--
Properties."
 
GOVERNMENT REGULATION
 
    All  pharmaceutical  manufacturers are  subject  to extensive  regulation of
their  activities,  including  research  and  development  and  production   and
marketing, by numerous governmental authorities in the U.S. and other countries.
In  the U.S., pharmaceutical products are  subject to rigorous regulation by the
Food and Drug  Administration (the  "FDA"). If a  company fails  to comply  with
applicable  requirements,  it may  be  subject to  administrative  or judicially
imposed sanctions such as civil  penalties, criminal prosecution of the  Company
or  its  officers  and  employees, injunctions,  product  seizure  or detention,
product recalls, total or  partial suspension of production  and FDA refusal  to
approve  pending  premarket  approval applications  or  supplements  to approved
applications.
 
    The Company initially intends to emphasize OTC drug products that  generally
do  not  require  FDA premarketing  approval  under  the FDA's  OTC  drug review
process. Products subject to  final monographs issued by  the FDA, however,  are
subject  to  various  FDA  regulations  such  as  those  outlining  current Good
Manufacturing Practice ("cGMP") requirements, general and specific OTC  labeling
requirements (including warning statements), the restriction against advertising
for  conditions other than those stated in product labeling, and the requirement
that OTC  drugs contain  only suitable  inactive ingredients.  OTC products  and
manufacturing  facilities,  including  the Company's  new  OraSolv manufacturing
facility, are subject to FDA inspection,  and failure to comply with  applicable
regulatory  requirements  may  lead  to  administrative  or  judicially  imposed
penalties, as well as delays.
 
    Future marketing of  products not  formulated in compliance  with final  OTC
drug  monographs typically will require a formal  submission to the FDA, such as
an Abbreviated New Drug  Application ("ANDA"), New  Drug Application ("NDA")  or
Supplement  to existing New Drug Application  ("SNDA"), and ultimate approval by
the FDA.  This  application and  approval  process  can be  expensive  and  time
consuming,  typically taking several years to complete. Further, there can be no
assurance that approvals can be obtained, or that any such approvals will be  on
the  terms or have the scope necessary for successful commercialization of these
products. The Company expects that any required FDA approvals in connection with
the introduction  of  new,  non-monographed  products would  be  sought  by  the
Company's  corporate partners.  Marketing of such  products could  be delayed or
prevented because of  this process. Even  after an  ANDA, NDA or  SNDA has  been
approved,  existing FDA  procedures may  delay initial  product shipment. Delays
caused by the FDA approval process may materially reduce the period during which
there is an exclusive right to exploit patented products or technologies.
 
    Even if  any required  FDA approval  has  been obtained  with respect  to  a
product,  foreign regulatory  approval of  a product  must be  obtained prior to
marketing the  product internationally.  Foreign approval  procedures vary  from
country  to country  and the  time required  for approval  may delay  or prevent
marketing. Although the Company  expects to rely  on its pharmaceutical  company
partners  to  obtain any  necessary government  approvals in  foreign countries,
there can be  no assurance  that such  approvals will  be obtained  in a  timely
fashion, if at all.
 
                                       8
<PAGE>
    The  Company is also  subject to regulation under  various federal and state
laws  regarding,  among   other  things,   occupational  safety,   environmental
protection,  hazardous substance control and  product advertising and promotion.
In  connection   with  its   research  and   development  activities   and   its
manufacturing,  the Company is subject to  federal, state and local laws, rules,
regulations and policies  governing the use,  generation, manufacture,  storage,
air emission, effluent discharge, handling and disposal of certain materials and
wastes.  The  Company  believes  that  it  has  complied  with  these  laws  and
regulations in all material respects  and it has not  been required to take  any
action  to  correct  any  material  noncompliance.  In  the  past,  the  Company
manufactured an herbicide product for a large chemical company involving certain
hazardous materials and chemicals. The  herbicide product was manufactured in  a
separate  facility from the Eden Prairie facility. The Company believes that its
safety procedures for  handling and  disposing of such  materials and  chemicals
complied  with  the requirements  of  federal and  state  law. See  "Business --
Government Regulation."
 
RAPID CHANGES IN THE HEALTHCARE INDUSTRY
 
    The healthcare  industry  is changing  rapidly  as the  public,  government,
medical  professionals,  third-party  payors  and  the  pharmaceutical  industry
examine ways  to contain  or reduce  the cost  of health  care. Changes  in  the
healthcare  industry could  impact the  Company's business,  particularly to the
extent that the Company develops products for prescription drug applications. In
certain foreign markets pricing or profitability of prescription pharmaceuticals
is subject to government control. In the United States there have been, and  the
Company  expects that there will  continue to be, a  number of federal and state
proposals to implement  similar government control.  In addition, an  increasing
emphasis on managed care in the United States has increased and will continue to
increase  the  pressure  on  pharmaceutical pricing.  While  the  Company cannot
predict whether any such legislative or regulatory proposals will be adopted  or
the  effect such proposals or managed care efforts may have on its business, the
announcement of such proposals or efforts  could have a material adverse  effect
on the Company's ability to raise capital, and the adoption of such proposals or
efforts  could  have a  material adverse  effect on  the Company's  business and
financial condition. Further, to the extent that such proposals or efforts  have
a material adverse effect on other pharmaceutical companies that are prospective
corporate partners for the Company, the Company's ability to establish strategic
collaborations  may be  adversely affected.  In addition,  in both  domestic and
foreign markets, sales of products utilizing the Company's drug delivery systems
will depend in part on the availability of reimbursement from third-party payors
such as government  health administration authorities,  private health  insurers
and  other organizations.  Third-party payors  are increasingly  challenging the
price  and   cost-effectiveness   of   prescription   pharmaceutical   products.
Significant  uncertainty exists as to the reimbursement status of newly approved
healthcare products.  There can  be  no assurance  that products  utilizing  the
Company's  drug  delivery  systems will  be  considered cost  effective  or that
adequate  third-party  reimbursement   will  be  available   to  the   Company's
collaborators  to  maintain price  levels sufficient  to realize  an appropriate
return on the Company's investment in its drug delivery systems.
 
DEPENDENCE ON MANAGEMENT AND OTHER KEY EMPLOYEES
 
    The success of  the Company  and of its  business strategy  is dependent  in
large  part on the ability  of the Company to  attract and retain key management
and operating  personnel. Such  individuals are  in high  demand and  are  often
subject  to competing offers. In particular,  the Company's success will depend,
in part, on  its ability to  attract and  retain the services  of its  executive
officers and scientific and technical personnel. The loss of the services of one
or  more  members  of management  or  key  employees or  the  inability  to hire
additional personnel  as  needed may  have  a  material adverse  effect  on  the
Company.  The Company currently has no full-time chief financial officer, but is
actively recruiting to fill this position.
 
PRODUCT LIABILITY AND INSURANCE RISKS
 
    The Company's  business involves  exposure  to potential  product  liability
risks  that are  inherent in  the production  and manufacture  of pharmaceutical
products. Although the Company has not experienced any product liability  claims
to  date, any such claims  could have a material  adverse impact on the Company.
The Company maintains  a general  insurance policy which  includes coverage  for
product liability claims. There
 
                                       9
<PAGE>
can  be no assurance,  however, that the  Company will be  able to maintain such
insurance on acceptable terms, that the Company will be able to secure increased
coverage as the commercialization of its products proceeds or that any insurance
will provide adequate protection against potential liabilities.
 
CONTROL BY EXISTING STOCKHOLDERS
 
   
    Following this  offering, directors,  executive  officers and  five  percent
stockholders  of  the  Company,  and  certain  of  their  affiliates,  will  own
approximately 34.2%  of the  Company's outstanding  Common Stock  (approximately
32.6%  assuming  full  exercise  of  the  Underwriters'  over-allotment option).
Accordingly, these stockholders,  individually and as  a group, may  be able  to
influence  the  outcome of  stockholder  votes, including  votes  concerning the
election of directors, the adoption or amendment of provisions in the  Company's
Certificate  of Incorporation or Bylaws and  the approval of certain mergers and
other significant corporate transactions, including a sale of substantially  all
of  the Company's assets.  Such control by existing  stockholders could have the
effect of delaying, deferring or preventing a change in control of the  Company.
See "Principal and Selling Stockholders" and "Description of Capital Stock."
    
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
    The  Company's Common Stock currently trades  on the Nasdaq National Market.
The securities markets have from time to time experienced significant price  and
volume  fluctuations  that  may be  unrelated  to the  operating  performance of
particular companies.  The  market  prices  of the  equity  securities  of  many
publicly  traded pharmaceutical  and drug  delivery companies  in the  past have
been,  and  in  the  future   can  be  especially  volatile.  Announcements   of
technological  innovations or  new products by  the Company  or its competitors,
developments or disputes  concerning patents or  proprietary rights,  regulatory
developments   and   economic   and   other  external   factors,   as   well  as
period-to-period fluctuations in  the Company's  financial results,  may have  a
significant effect on the market price of the Company's Common Stock. See "Price
Range of Common Stock."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon  completion of this offering, based on the number of shares outstanding
on March  31, 1996,  the Company  will  have 8,840,099  shares of  Common  Stock
outstanding  (9,255,195 if the Underwriters'  over-allotment option is exercised
in full), of  which 2,800,000  are being  offered hereby  and of  which all  but
15,027  shares of Common  Stock will be  freely tradeable on  the public market,
subject in  certain cases  to  lock-up agreements  as described  below.  Certain
volume resale restrictions are imposed by the Securities Act of 1933, as amended
(the  "Securities  Act"), with  respect  to the  15,027  shares of  Common Stock
referenced above, which restrictions will expire in January 1997; however,  such
15,027  shares have been registered on a Form S-3 registration statement and may
be sold without such restrictions.  The Company, subject to certain  exceptions,
and  its officers,  directors and certain  stockholders holding  an aggregate of
approximately 2,668,487 shares of Common Stock after this offering, have  agreed
not to sell or otherwise dispose of any shares of Common Stock during the 90-day
period following the date of this Prospectus without the consent of Volpe, Welty
&  Company  on  behalf of  the  Underwriters.  Volpe, Welty  &  Company,  in its
discretion,  may  permit   such  sales   during  such   period  without   public
announcement. See "Shares Eligible for Future Sale."
    
 
ANTI-TAKEOVER PROVISIONS
 
    The  Board of  Directors is  authorized to issue  up to  5,000,000 shares of
preferred stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of those shares  without any further vote or action  by
the  Company's stockholders. The rights  of the holders of  Common Stock will be
subject to, and may be adversely affected  by, the rights of the holders of  any
preferred  stock that may be issued in  the future. Although there is no current
intention to do so,  the issuance of  preferred stock could  have the effect  of
delaying,  deferring or  preventing a  change in  control of  the Company, which
could deprive the Company's stockholders  of opportunities to sell their  shares
of  Common Stock  at a  premium. Additionally,  the Company  could adopt  in the
future one  or more  additional anti-takeover  measures, such  as a  stockholder
rights  plan, without first  seeking stockholder approval,  which measures could
also make a change in control of the Company more difficult. The Company is also
subject to provisions of the Delaware General Corporation Law that make  certain
business combinations more difficult.

ABSENCE OF DIVIDENDS; DILUTION
 
    The  Company has  never declared  or paid any  cash dividends  on its Common
Stock and does not anticipate paying  cash dividends in the foreseeable  future.
The  public offering price is substantially higher than the book value per share
of the outstanding Common Stock. Investors purchasing shares of Common Stock  in
this  offering  will  therefore  immediately  incur  substantial  dilution.  See
"Dilution." In addition, dilution  will occur upon  the exercise of  outstanding
stock  options and  warrants of  the Company  and may  occur upon  future equity
financings of the Company.
 
                                  THE COMPANY
 
    The Company was  incorporated in  Delaware in December  1986. The  Company's
principal executive offices are located at 10000 Valley View Road, Eden Prairie,
Minnesota 55344-9361, and its telephone number is (612) 947-8700.
 
                                USE OF PROCEEDS
 
   
    The  net proceeds to  the Company from  the sale of  the 1,000,000 shares of
Common Stock offered  by the  Company hereby (at  the public  offering price  of
$9.50   per  share)  are   estimated  to  be   $8,455,000  ($12,145,000  if  the
Underwriters' over-allotment option  is exercised in  full) after deducting  the
underwriting  discounts and commissions and  estimated offering expenses payable
by the Company. The Company will not  receive any of the proceeds from the  sale
of shares by the Selling Stockholders.
    
 
    The  Company expects to use the net proceeds from this offering primarily to
begin commercial  production  in its  new  manufacturing facility  and  to  fund
research  and development (including  preclinical and clinical  testing) for the
application of the OraSolv technology to pharmaceutical products. The balance of
the net proceeds will  be used for working  capital and other general  corporate
purposes.  The Company currently anticipates that the net offering proceeds will
be allocated as follows: 15% for the initiation of production; 20% for continued
research and development of new, improved OraSolv technology including  improved
efficacy   pharmaceuticals;  30%   for  research  and   development  of  OraSolv
prescription pharmaceuticals and related required clinical and consumer studies;
30% for  working capital;  and 5%  for  capital expenditures.  There can  be  no
assurance,  however, that  the net proceeds  of the offering  will ultimately be
utilized as currently anticipated. The amount and timing of the expenditures  of
the  net proceeds for these purposes  will depend on numerous factors, including
the status of the Company's product development efforts, the Company's  business
development  activities, the result of  clinical trials, the regulatory approval
process and competition. The Company may also use a portion of the net  proceeds
to  acquire  complementary businesses,  products  or technologies,  although the
Company has no agreements and is not involved in any negotiation with respect to
any such transactions.
 
    The Company believes that its available cash and cash equivalents,  together
with  the  net proceeds  of  this offering  and  the interest  thereon,  will be
sufficient to meet its capital requirements  at least through the first  quarter
of 1997. Pending application of the net proceeds as described above, the Company
intends   to  invest   the  net   proceeds  of   the  offering   in  short-term,
interest-bearing, investment-grade securities.

to dividend policy will be made at  the discretion of the Board of Directors  of
the  Company  and will  depend  on a  number  of factors,  including  the future
earnings, capital requirements, financial condition and future prospects of  the
Company and such other factors as the Board of Directors may deem relevant.

                                    DILUTION
 
   
    The  net  tangible  book  value  of  the  Company  at  March  31,  1996, was
approximately $12,392,000  or $1.58  per share.  "Net tangible  book value"  per
share  represents the amount  of the Company's total  tangible assets less total
liabilities divided by the number of  shares of Common Stock outstanding.  After
giving  effect to the sale  by the Company of 1,000,000  of the shares of Common
Stock offered hereby (at the public offering price of $9.50 per share and  after
deducting   estimated  underwriting  discounts  and  commissions  and  estimated
offering expenses payable by the Company), the pro forma net tangible book value
of the Company at  March 31, 1996 would  have been approximately $20,847,000  or
$2.36 per share. This represents an immediate increase in such net tangible book
value  of $.78 per share  to existing stockholders and  an immediate dilution of
$7.14 per share to new investors. The following table illustrates this per share
dilution:

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    EXCEPT  FOR  THE  HISTORICAL  INFORMATION  CONTAINED  HEREIN,  THE FOLLOWING
DISCUSSION  CONTAINS   FORWARD-LOOKING  STATEMENTS   THAT  INVOLVE   RISKS   AND
UNCERTAINTIES.  THE COMPANY'S ACTUAL RESULTS  COULD DIFFER MATERIALLY FROM THOSE

GENERAL
 
    The Company  was  founded in  1986  to develop  effervescent  drug  delivery
technologies and focused initially on liquid effervescents. CIMA continues to be
a  development stage  company. CIMA's business  focus has evolved  over the last
several years with the development and patenting of OraSolv, an oral dosage form
which  incorporates  microencapsulated  drug  ingredients  into  a  tablet  that
dissolves  quickly in the  mouth without chewing or  water and which effectively
masks the taste of the medication  being delivered. In 1993, following  issuance
of the U.S. patent covering OraSolv, the Company began to emphasize and focus on
the  development of  OraSolv products  and currently  focuses primarily  on such
products.
 
    At March 31, 1996, the Company  has accumulated net losses of  approximately
$30,899,000.  The  Company's revenues  have been  from  product sales  using the
Company's AutoLution (a  liquid effervescent) technology,  license fees paid  by
corporate   partners  in   consideration  of   the  transfer   of  rights  under
collaboration agreements, and  research and development  fees paid by  corporate
partners  to fund  the Company's research  and development  efforts for products
developed under  such  agreements. To  date,  such revenues  have  been  derived
primarily   from  manufacturing   agreements  with  third   parties  for  liquid
effervescent and  other products,  and  to a  lesser  extent from  research  and
development  fees and licensing arrangements,  the latter generated primarily in
the last five  years. Revenues from  manufacturing liquid effervescent  products
under  agreements with third parties have decreased as a result of the Company's
decision to discontinue manufacturing that  product and focus on developing  its
OraSolv  technology.  The last  revenues  for manufacturing  liquid effervescent
products  were  recognized  in   1995.  In  addition   to  revenues  from   such
manufacturing,  research and development  and licensing, the  Company has funded
operations from private sales  of equity securities,  realizing net proceeds  of
approximately $25,963,000. In July 1994, the Company completed an initial public
offering  of shares of its Common Stock, realizing net proceeds of approximately
$16,379,000.
 
    The Company expects that losses will  continue through at least 1997.  Costs
and  expenses are expected  to remain relatively  stable as the  majority of the
necessary research  and development  personnel have  already been  hired. It  is
expected  that additional  manufacturing personnel  will be  added and operating
expenses will increase  at such  time as  the Company  initiates the  commercial
production of OraSolv products.
 
    The  Company's ability to generate revenues is dependent upon its ability to
enter into and be successful  in collaborative arrangements with  pharmaceutical
and  other healthcare companies  for the development  and manufacture of OraSolv
products to  be marketed  by these  corporate partners.  The Company  is  highly
dependent  upon the  efforts of  the corporate  partners to  successfully market
OraSolv products.  Although the  Company believes  these partners  will have  an
economic  motivation to market these products  vigorously, the amount and timing
of resources  to be  devoted to  marketing are  not within  the control  of  the
Company.  These partners independently  could make material  marketing and other
commercialization decisions which  could adversely affect  the Company's  future
revenues. Moreover, certain of the Company's products are seasonal in nature and
the  Company's revenues could vary materially  from quarter to quarter depending
on which of such products, if any, are then being marketed.
 
    Since the Company's initial public offering in 1994, the Company has put  in
place  a  substantially  new  management  team.  This  new  management  team was
responsible for  the  buildout and  validation  of the  Company's  Eden  Prairie
manufacturing facility. See "Management -- Directors and Executive Officers."

RESULTS OF OPERATIONS
 
  YEARS ENDED DECEMBER 31, 1993, 1994 AND 1995
 
    The  Company's results  of operations for  the year ended  December 31, 1995
reflect increased emphasis  on the  development of OraSolv  products. Net  sales
decreased  from $1,857,000 in 1993 and $1,451,000 in 1994 to $151,000 in 1995 as
the Company ceased to manufacture liquid effervescent and other products. In the
future, the  Company  does  not expect  to  derive  revenues from  the  sale  of
contract-manufactured  liquid effervescent  products. Research,  development and
licensing revenues  were $368,000,  $1,168,000 and  $684,000 in  1993, 1994  and
1995,  respectively. The licensing revenues in  1994 and 1995 reflect receipt of
payments  under   license   and  development   agreements   with   multinational
pharmaceutical  companies that provided for  licensing fees, milestone payments,
royalties and manufacturing  fees. So  long as  the Company  has relatively  few
agreements  with corporate partners, research and development fees and licensing
revenues will tend to fluctuate on a quarter to quarter basis.
 
    Cost of goods sold was $2,844,000, $2,799,000 and $240,000 in 1993, 1994 and
1995, respectively. The  decline in 1994  and 1995 resulted  from the  Company's
decision  to discontinue manufacturing the  liquid effervescent product line and
focus on  the  development  of  the OraSolv  technology.  Research  and  product
development  expenses were $1,857,000  in 1993 compared  with $3,549,000 in 1994
and $6,505,000 in  1995. The  increase from  1994 to 1995  was the  result of  a
product  development/optimization  charge  of  $1,385,000  from  an  independent
consultant for improving  product taste  and packaging of  OraSolv products.  In
addition,  the costs associated with  validating the OraSolv production facility
and production process for the Company's corporate partners have been charged to
research and  development. Selling,  general  and administrative  expenses  were
$1,208,000 in 1993 compared with $2,972,000 in 1994 and $3,658,000 in 1995. This
increase  resulted from the  Company's building of  an infrastructure to support
the OraSolv business, together with increased expenses related to marketing  and
one-time  expenses for  changes in senior  management. The  Company expects such
changes in senior management will reduce general and administrative expenses  in
1996.
 
    Net  interest income was $5,500  in 1993 compared with  $452,000 in 1994 and
$448,000 in 1995, reflecting  interest income from  increased cash levels  after
the Company's initial public offering in 1994.
 
  THREE MONTHS ENDED MARCH 31, 1995 AND 1996
 
    The  Company's results  of operations for  the quarter ended  March 31, 1996
reflect increased emphasis  on development  of OraSolv  products. Product  sales
declined  from $11,000 in the  first quarter of 1995 to  no product sales in the
first quarter of 1996 as the  Company ceased to manufacture liquid  effervescent
and   other  products.  The  Company  does  not  intend  to  manufacture  liquid
effervescent products in the future. Research and development fees and licensing
revenues were  $215,000 and  $392,000 in  the first  quarter of  1995 and  1996,
respectively.  These  increased  research  and  development  fees  and licensing
revenues reflect the signing of  license option and development agreements  with
multinational   pharmaceutical  companies  that   provide  for  licensing  fees,
milestone payments, royalties and  manufacturing fees. Research and  development
fees  and licensing  revenues will  tend to  fluctuate on  a quarter  to quarter
basis.
 
    Cost of goods sold decreased  from $59,000 in the  first quarter of 1995  to
zero  in the first quarter  of 1996. Costs of goods  sold will increase when the
Company begins commercial production and sales of OraSolv products. Research and
product development expenses decreased from  $2,292,000 in the first quarter  of
1995 to $1,376,000 in the first quarter of 1996. This decrease was the result of
a  product  development/ optimization  charge in  the first  quarter of  1995 of
$1,068,000 from  an  independent  consultant for  improving  product  taste  and
packaging  of  OraSolv products.  Selling,  general and  administrative expenses
decreased due to  downsizing from  $1,019,000 in the  first quarter  of 1995  to
$784,000  in  the first  quarter  of 1996.  Net  interest income  decreased from
$170,000 in the first quarter  of 1995 to $39,000 in  the first quarter of  1996
due to lower cash balances.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The  Company has financed  its operations to  date primarily through private
and public  sales  of its  equity  securities and  revenues  from  manufacturing
agreements.    Through    March    31,    1996,    CIMA    had    received   net
 
                                       16
<PAGE>
offering  proceeds  from  such  private   and  public  sales  of   approximately
$43,300,000  and had  net sales  from manufacturing  agreements of approximately
$13,800,000. Among other things, these funds were used to purchase approximately
$14,300,000 of capital equipment, including approximately $7,500,000 in the last
two quarters  of 1994  in  connection with  completing  the Company's  new  Eden
Prairie  manufacturing facility. In July 1994,  the Company completed an initial
public offering  of  shares of  its  Common  Stock, realizing  net  proceeds  of
approximately  $16,400,000. The funds  raised in CIMA's  initial public offering
have been used to buildout the manufacturing facility, purchase and validate the
appropriate  production  equipment,  complete   the  research  and   development
facilities and purchase the necessary equipment for that facility.
 
    The  Company's  long-term  capital requirements  will  depend  upon numerous
factors, including the status of  the Company's collaborative arrangements,  the
progress  of  the Company's  research and  development  programs and  receipt of
revenues from sales of the Company's  products. Cash and cash equivalents,  were
$2,517,000  at March 31, 1996. The Company believes that its currently available
funds will  meet its  needs through  the  second quarter  of 1996.  The  Company
believes  that the net proceeds to the Company from this offering, combined with
its currently  available  funds and  excluding  any  license fees  that  may  be
received  in the future, will meet its  needs at least through the first quarter
of 1997.  The Company  will need  to raise  additional funds  through public  or
private  financings,  including  equity  financing  which  may  be  dilutive  to
stockholders. There can be no assurance that  the Company will be able to  raise
additional  funds if its capital resources are  exhausted, or that funds will be
available on terms attractive to the Company.
 
    The Company has not  generated taxable income through  March 1996. At  March
31,  1996, the  net operating losses  available to offset  future taxable income
were approximately $31,397,000.  Because the Company  has experienced  ownership
changes,  pursuant to Internal  Revenue Code regulations,  future utilization of
the operating loss  carryforwards will be  limited in any  one fiscal year.  The
carryforwards  expire beginning in 2001. As a result of the annual limitation, a
portion of these carryforwards may  expire before ultimately becoming  available
to reduce potential federal income tax liabilities.

                                    BUSINESS
 
OVERVIEW
 
    CIMA  is a  drug delivery company  focused primarily on  the development and
manufacture  of  pharmaceutical  products   based  upon  its  patented   OraSolv
technology.    OraSolv   is    an   oral    dosage   formulation   incorporating
microencapsulated active drug ingredients into a tablet which dissolves  quickly
in  the mouth without chewing or water  and which effectively masks the taste of
the medication being delivered. OraSolv's fast-dissolving capability may  enable
patients  in certain age groups or those with a variety of conditions that limit
their ability to swallow  conventional tablets to receive  medication in a  more
convenient  oral  dosage  form.  The  Company  believes  that  OraSolv  is  more
convenient than traditional  tablet-based oral  dosages as it  does not  require
water  to be  ingested, thereby  enabling immediate  medication at  the onset of
symptoms. In addition, OraSolv can provide more accurate administration of doses
than liquid or suspension formulations as no measuring is required. The  Company
believes OraSolv's ability to be easily ingested by patients will foster greater
patient compliance, thereby improving therapeutic outcomes and reducing costs in
the healthcare system.
 
    CIMA's  business  focus  has  evolved  over  the  last  several  years. From
inception  until  1992,  the  Company  focused  on  the  development  of  liquid
effervescent  products  and  technologies.  In 1993,  the  U.S.  patent covering
OraSolv was issued and the Company, perceiving a greater commercial opportunity,
shifted its  focus to  the  development of  OraSolv  products. CIMA  intends  to
commercialize  its OraSolv technology through collaborations with pharmaceutical
and other healthcare companies under which the Company will manufacture  OraSolv
formulations  of its collaborators' pharmaceutical  products. Since the issuance
of the OraSolv patent in 1993, the Company has:
 
    - Completed construction of a 75,000  square foot manufacturing facility  in
      Eden  Prairie,  Minnesota,  which has  been  registered with  the  FDA and
      licensed by the State of Minnesota.
 
    - Entered into a License and Development Agreement with Glaxo to develop  an
      OraSolv (liquid effervescent) version of Glaxo's Zantac.
 
    - Entered  into a  License Agreement  and Development  and a  License Option
      Agreement with SmithKline Beecham to develop a series of OraSolv  versions
      of   SmithKline   Beecham   products   for   international   and  domestic
      distribution.
 
    - Entered into  agreements  with  three other  potential  partners  for  the
      development and manufacture of OraSolv products.
 
    - Entered  into  a License  and Supply  Agreement with  Merck to  provide an
      AutoLution (a liquid effervescent) version of Merck's Pepcid AC.
 
    - Added key scientific, technical and management personnel.
 
BACKGROUND
 
    DRUG DELIVERY TECHNOLOGY
 
    Patient medications are available in a variety of delivery forms,  including
solid  dosage forms,  liquids, effervescents,  transdermal delivery  methods and
intramuscular and intravenous injections.  Enteral medication delivery  includes
those  medications delivered through the stomach, including tablets, liquids and
effervescents. Enteral medications are frequently patient-administered,  because
of   their  non-invasive  delivery  method.  Parenteral  medications  are  those
delivered by  injection.  Parenteral medications  are  often administered  by  a
healthcare provider.
 
    The  Company  believes the  convenience of  patient administration  has made
enteral  medications  in  general,  and  tablets  in  particular,  popular  with
patients,  providers and  payors. Industry  sources estimate  that patients most
frequently receive medications in an oral tablet form. However, children and the
elderly, as well  as those  with certain physiological  or medical  indications,
frequently  experience difficulty  in swallowing  tablets. These  patients often
receive medications  in  liquid  or effervescent  form,  or  through  parenteral
methods  as an alternative to  tablets. The Company believes  that tablets are a
more convenient, accurate and
 
                                       18
<PAGE>
effective medication form than are liquids or effervescents (which may spill  in
the  process of  administering the medication,  especially to  children) and are
easier for patients to self-administer than parenteral therapeutics.
 
    RECENT TRENDS IN THE HEALTHCARE AND PHARMACEUTICAL INDUSTRIES
 
    The healthcare industry has experienced  significant change in the past  and
the  Company expects  this change  to continue  for the  foreseeable future. The
emergence of managed care organizations has focused providers and payors on  the
efficient  utilization of healthcare  resources. In addition,  the trend towards
the "capitation" of fees, or management of a patient's health requirements for a
pre-determined, regular payment, has created an awareness among providers of the
cost-effectiveness of  various  medical  treatments.  Healthcare  providers  and
payors  have implemented a variety  of strategies to reduce  the cost of medical
care, including the use of generic versions of prescription and non-prescription
drugs, the use of non-prescription remedies  and the use of therapies that  have
high  patient compliance. The Company  believes that patient non-compliance with
medicinal dosing regimens is widespread, and that such non-compliance results in
unnecessary costs to the healthcare system.
 
    These changes  in  the  healthcare  industry have  also  had  an  impact  on
participants  in the pharmaceutical industry.  In particular, a greater emphasis
on cost effectiveness  by providers  and payors has  resulted in  pharmaceutical
companies   developing  products  that   reduce  the  cost   of  therapy.  These
pharmaceutical companies have responded  by developing treatments with  improved
efficacy,  reduced  complications and  side effects,  easier delivery  and lower
costs. The  focus on  cost-effectiveness  has also  led  to the  development  of
generic  versions  of  off-patent prescription  drugs.  Increasingly, healthcare
payors and providers have embraced generic equivalents of branded drugs  because
generic   drugs  provide   a  substantial   cost  savings.   In  addition,  many
pharmaceutical  companies  are   extending  their  presence   in  a   particular
therapeutic area with the introduction of a non-prescription, or OTC, version of
a prescription drug. Many patients and providers have indicated a preference for
OTC  versions  of  prescription  formulations because  of  the  convenience that
patient-administration of OTC therapies provides as well as the cost savings. In
addition, healthcare providers and payors  have indicated a continuing  interest
in   therapies  that  improve  patient  compliance  which  ultimately  leads  to
significant healthcare cost savings.
 
    As  these  pharmaceutical  companies  adjust  to  the  evolving   healthcare
industry,  they  must differentiate  their products  in an  increasingly crowded
therapeutic market.  To  do this  effectively,  they must  develop  products  or
product  extensions that can successfully compete  in the generic and OTC market
for  drugs,  develop  products  or  product  extensions  that  enhance   patient
compliance,  and do all  of this within a  highly regulated and cost-constrained
environment.
 
MARKET OPPORTUNITY
 
    The Company  believes that  its OraSolv  drug delivery  system will  provide
benefits  to patients as well as healthcare industry providers and payors. These
benefits, in turn, should provide marketing advantages to CIMA's  pharmaceutical
partners.  The benefit  to patients is  convenience, which  the Company believes
will result  in  improved  compliance  with dosing  regimens.  The  benefits  to
providers  and payors  are lower costs  resulting from  such improved compliance
with dosing regimens. The benefits to pharmaceuticals partners are the potential
for brand  differentiation  and the  ability  to retain  brand  integrity  using
proprietary technology.
 
    ADVANTAGES FOR PATIENTS, PROVIDERS AND PAYORS
 
    The Company believes a broad group of patients will benefit from the OraSolv
rapid  dissolve technology  because it  enables immediate  medication at symptom
emergence and facilitates conformance to dosing regimens. Patient non-compliance
with dosing  regimens  has  been  associated with  increased  costs  of  medical
therapies  by  prolonging  treatment  duration,  increasing  the  likelihood  of
secondary or tertiary disease manifestation and contributing to over-utilization
of medical personnel and facilities. By improving patient compliance,  providers
and payors may reduce unnecessary expenditures and improve therapeutic outcomes.
Reduction  of expenditures  is an increasingly  important issue  to providers as
capitated payment plans become more prevalent in the healthcare industry.
 
                                       19
<PAGE>
    In addition to  the general  market applications, the  Company believes  the
OraSolv  technology provides benefits to certain patient groups which experience
significant difficulty  in  swallowing  tablets.  Such  patient  groups  include
children  and the elderly and patients  with certain anatomical or physiological
deformities, certain disease indications or medication-associated dysphagia. The
Company  has  completed   quantitative  consumer  testing   with  children   and
qualitative testing with physicians for the elderly which indicate the potential
for  these demographic groups to better comply  with dosing regimens and thus to
benefit from the OraSolv technology.
    ADVANTAGES FOR PHARMACEUTICAL PARTNERS
 
    The Company believes that pharmaceutical companies are facing challenges  to
adjust to the evolving healthcare industry. These challenges include: the impact
of  generic competition, which generally  results in lower pricing  as well as a
loss of  market  share;  the  impact  of the  increased  role  of  managed  care
organizations,  forcing increased  economic considerations in  patient care, the
results of  which can  include shorter  therapies and  therapeutic  substitution
(including  less expensive products);  and the need  to maintain brand integrity
with its inherent economic benefits.
 
    Pharmaceutical companies are addressing these  issues in several ways.  They
are attempting to develop new product forms which will demonstrate a medical and
economic  benefit to the patient. They are also trying to develop products which
will help to improve patient compliance, which should result in a patient's more
rapid return to health. Finally, they are attempting to use approaches which can
be patented or provide  a technological differentiation in  order to reduce  the
threat of competition. The Company believes that the OraSolv technology provides
a means for its pharmaceutical partners to meet each of these challenges.
 
TECHNOLOGY
 
    ORASOLV
    The  Company's  OraSolv technology  is an  oral  dosage form  which combines
taste-masked,  microencapsulated   drug   ingredients   with   an   effervescent
disintegration  agent.  The  effervescent  disintegration  agent  aids  in rapid
dissolution of  the  tablet,  permitting swallowing  before  the  pharmaceutical
ingredients  are released. The OraSolv  tablet dissolves quickly without chewing
or water  and allows  for effective  taste-masking  of a  wide variety  of  both
prescription and OTC active drug ingredients.
    The  microencapsulation of the drug ingredients  used in OraSolv products is
accomplished using a  variety of  coating techniques,  including spray  coating,
spray  drying, spray  congealing, melt  dispersion, phase  separation or solvent
evaporation methods. Certain of these coating techniques have been developed  by
the  Company's  scientists in  collaboration  with coating  materials suppliers.
Coating materials are  designed to  prevent the  active drug  ingredient in  the
OraSolv  tablet  from coming  in contact  with  the taste  buds and  provide for
immediate release of the active ingredient in the stomach. Coating materials are
chosen based  on the  dose and  taste of  the active  ingredients. A  series  of
experiments   is  then  performed  to   determine  the  suitability  of  various
microencapsulation techniques.  From these  experiments, a  technique is  chosen
based   on  reproducibility,  stability,  effectiveness  in  taste  masking  and
cost-effectiveness.  The  microencapsulated  drug  is  then  combined  with  the
fast-dissolving  tablet materials, which can include  a variety of flavoring and
coloring agents,  one  or  more  sweetening  agents  and  commonly  used  tablet
excipients,  such as binding agents and lubricants. In addition, an effervescent
system composed of a dry acid and a  dry base is added to the tablet  excipients
to facilitate a mild effervescent reaction when the tablet contacts saliva. This
effervescent  reaction accelerates the disintegration  of the tablet through the
release of carbon  dioxide. As  the OraSolv  tablet dissolves,  it releases  the
microparticles of drug into the saliva forming a micro-suspension of the drug in
the  saliva. This microencapsulated  drug suspension enters  the stomach through
the normal swallowing process.
    AUTOLUTION
    The Company's AutoLution technology is a drug delivery system that creates a
liquid effervescent  solution  from  dry  drugs  or  chemicals.  The  technology
involves the preparation of the active ingredients into a tablet or powder which
is  added to water to create a liquid drug solution. Since 1992, the Company has
shifted its  focus away  from  the development  of  AutoLution products  to  the
development  of OraSolv-based products. The Company will continue to develop its
AutoLution technology under  contractual agreements with  corporate partners  or
other  third parties, but it will  no longer contract manufacture products using
this technology.
 
                                       20
<PAGE>
STRATEGY
 
    The  Company's goal is  to have its OraSolv  technology incorporated into as
many pharmaceutical  products as  possible with  an emphasis  on  pharmaceutical
products which command a large market share or are in large market segments. The
Company  has developed a  strategic plan to accomplish  this goal. The Company's
primary strategies are to:
 
    - COLLABORATE WITH CORPORATE PARTNERS FOR MARKETING OF PRODUCTS. The Company
      has entered into  and intends to  continue to enter  into agreements  with
      pharmaceutical  and  other healthcare  companies  for the  development and
      marketing of products that incorporate the OraSolv technology. The Company
      will refine the OraSolv formulation  of a particular oral therapeutic  and
      manufacture  it for its collaborators. These collaborators will market and
      sell the OraSolv versions  of the therapeutic.  The Company believes  this
      strategy  will  reduce  the  time required  to  market  products  and take
      advantage of the industry knowledge and presence of its partners.
 
    - FOCUS INITIALLY ON OTC APPLICATIONS. The Company is focusing initially  on
      developing OraSolv products for the OTC cough/cold/flu, allergy and sinus,
      and  analgesic  markets.  The Company  intends  to target  both  adult and
      pediatric applications. The Company believes  that OTC products which  are
      subject  to the FDA's OTC drug  review process can generally be introduced
      without FDA  preapproval  and  thus  can  generate  revenues  sooner  than
      prescription  products. The Company  believes that OTC  products using its
      OraSolv delivery  system can  establish  distinct brand  identities  among
      otherwise largely undifferentiated OTC products, particularly in the large
      but competitive cough/cold/flu, allergy and sinus, and analgesic markets.
 
    - PURSUE  OPPORTUNITIES  IN  OTC  SWITCH PRODUCTS.  The  Company  intends to
      develop OraSolv  products  for drugs  that  are being  switched  from  the
      prescription  to the OTC market. The Company believes that as prescription
      products are switched into the  OTC market, pharmaceutical companies  will
      seek  methods for product  differentiation. The Company  believes that the
      OraSolv delivery system offers  significant differentiation potential  for
      these products. The Company's initial focus in this area is in the gastric
      relief  market, where  opportunities have been  created by  the recent FDA
      approval of  the switch  to  OTC of  three significant  anti-ulcer  drugs,
      Zantac  75, Pepcid  AC and  Tagamet HB,  and expiration  of the  patent on
      Tagamet.
 
    - DEVELOP   SELECTED   PRESCRIPTION   DRUG   APPLICATIONS.The   Company   is
      investigating the development of OraSolv pediatric antibiotic products and
      expects   in  the  future  to  develop  certain  other  prescription  drug
      applications. Qualitative  market  research studies  (focus  groups)  with
      pediatricians conducted by the Company have demonstrated a strong interest
      by  this group in utilizing OraSolv technology to improve compliance among
      children taking antibiotic products. Other potential OraSolv  prescription
      applications include anti-nauseants, psychotherapeutics and cancer therapy
      drugs.  OraSolv products may offer  improved taste acceptance and improved
      compliance with respect to these drugs. They may also offer benefits where
      patients have difficulty swallowing tablets or ingesting liquids.
 
    - DEVELOP PROPRIETARY  TECHNOLOGIES.  The  Company intends  to  continue  to
      develop  proprietary technology and  obtain patents thereon.  To date, the
      Company  has  five  U.S.  and  two  Australian  patents  and  nine  patent
      applications. The Company believes that patented products and technologies
      provide attractive marketing features for use by its corporate partners.
 
    - RETAIN  MANUFACTURING RIGHTS. The  Company intends to  continue to develop
      OraSolv formulations  of  oral  therapeutics  for  its  collaborators,  to
      manufacture  commercial quantities  of these  products in  its facility in
      Eden Prairie, and  to rely  on its collaborators  to market  and sell  the
      OraSolv  formulations. The  Company believes  this strategy  enables it to
      better and  more  effectively  manage  increasing  manufacturing  volumes,
      control  quality of the products it  manufactures and manufacture in small
      or varying  batch sizes,  each  of which  provide  it with  a  competitive
      business advantage.
 
    - RETAIN  OWNERSHIP OF PRODUCTS DEVELOPED IN COLLABORATIONS. The Company has
      retained and  intends  to continue  to  retain ownership  of  the  OraSolv
      formulations developed for its collaborators. The
 
                                       21
<PAGE>
      Company  believes this  practice will provide  it with  the flexibility of
      entering into  collaborations with  other  potential partners  should  the
      initial partner decide not to pursue the commercialization of a particular
      OraSolv product.
 
TARGET MARKETS
 
    KEY OTC MARKETS
 
    OTC  COUGH/COLD/FLU,  ALLERGY AND  SINUS.   This  large market  is generally
segmented into cough/cold/flu, allergy, and sinus categories with  approximately
77%  of U.S. sales in  terms of dollars in  cough/cold/flu products, and 12% and
11%  each  in  the  allergy   and  sinus  categories,  respectively,  in   1993.
Approximately  61% of sales in this market are of products using tablet, capsule
and lozenge dosage forms while the remaining 39% of sales are of products  using
liquid  dosage  forms. This  market  is highly  competitive.  The cough/cold/flu
category is seasonal  and is characterized  by frequent new  product entries  as
companies  attempt  to gain  market share  through product  differentiation. The
Company has  entered  into  an agreement  with  a  multinational  pharmaceutical
company to develop a series of products for this market. See "-- Agreements With
Corporate   Partners."   The  Company   is   also  pursuing   other  development
opportunities in this market.
 
   
    OTC ANALGESICS.    This  market  includes  the  following  market  segments:
acetaminophen,  which represented approximately 48% of U.S. dollar sales in this
market in 1993; ibuprofen,  which represented approximately  30% of such  sales;
and  aspirin, which represented  approximately 22% of  such sales. New Rx-to-OTC
switch products (e.g.,  ketoprofen and naproxen  sodium), have recently  entered
this  market  and  are expected  to  achieve significant  growth.  The Company's
initial focus in this market is on acetaminophen, the dominant segment, and  the
fast-growing  segments  of  the  Rx-to-OTC products,  as  well  as  on analgesic
combinations. The Company is pursuing several development opportunities in  this
market.
    
 
    GASTRIC RELIEF.  The Company believes that the gastric relief market for OTC
products  will  grow as  the patents  on  certain anti-ulcer  prescription drugs
expire. For example, the  patent on a  significant anti-ulcer prescription  drug
recently  expired. Generic versions  of this drug are  being introduced into the
prescription market  and  also  switched  into the  OTC  market.  These  generic
versions  may  be  considered  therapeutically  equivalent  to  other  patented,
anti-ulcer  prescription  drugs.  The  Company  believes  that  OraSolv  is   an
attractive  dosage form for  the gastric relief market  because it could provide
taste masking for anti-ulcer drugs, which tend to have a disagreeable taste.
 
    PRESCRIPTION DRUG MARKET
 
    The Company is investigating the development of OraSolv pediatric antibiotic
products and expects in the future to develop OraSolv products for  prescription
drug   applications,  including   products  for   which  Abbreviated   New  Drug
Applications may be  filed for  special niche branded  use. Certain  antibiotics
must  be manufactured at  a separate facility  from other pharmaceuticals, which
may  impede  the   development  of  such   products.  Other  potential   OraSolv
prescription  applications include anti-nauseants, psychotherapeutics and cancer
therapy  drugs.  The   Company  also  believes   that  additional   prescription
opportunities  exist  in  the analgesic,  anti-inflammatory  and cough/cold/flu,
allergy and sinus markets.
 
    PEDIATRIC VITAMINS
 
    The Company has in the past developed and may in the future develop  OraSolv
products  for  the pediatric  vitamin  market. The  Company  has focused  on the
pediatric vitamin market rather than on the larger adult vitamin market  because
the  Company  believes  that OraSolv's  improved  taste acceptance  and  ease of
administration can  offer  greater compliance  in  the pediatric  market,  where
compliance with a regular dosage regimen can be difficult to achieve.
 
AGREEMENTS WITH CORPORATE PARTNERS
 
    The  Company's  business development  efforts are  focused on  entering into
development, licensing  and  manufacturing agreements  with  pharmaceutical  and
other  healthcare companies. Under these  agreements, the corporate partner will
be responsible  for marketing  the Company's  products either  worldwide, or  in
specified markets or territories. The collaborative arrangements typically begin
with a research and development phase which, if successful, may be followed by a
development and license option agreement for
 
                                       22
<PAGE>
development  of product prototypes and then license and manufacturing agreements
for commercialization of such products.  Alternatively, the Company may  develop
product   prototypes  internally   and  enter   directly  into   a  development,
manufacturing or license agreement for commercialization of those products.
 
    The Company's  future ability  to  generate revenue  is dependent  upon  the
Company's  ability to enter into  collaborative arrangements with pharmaceutical
and other corporate partners to develop  products that meet the requirements  of
its  corporate  partners  and  upon the  marketing  efforts  of  these corporate
partners. The Company believes these  partners will have an economic  motivation
to market the Company's products; however, the amount and timing of resources to
be  devoted  to marketing  are  not within  the  control of  the  Company. These
partners independently could make material marketing and other commercialization
decisions which could adversely affect the Company's future revenues. Failure of
these partners  to  market the  Company's  products successfully  would  have  a
material  adverse effect  on the  Company's financial  condition and  results of
operations. Moreover,  certain of  the Company's  OTC products  are seasonal  in
nature  and  the Company's  revenues could  vary  materially from  one financial
period to another depending on  which of such products,  if any, are then  being
marketed.  In  an attempt  to alleviate  such  risk, the  Company is  focused on
developing for its partners a mix of OTC and prescription products. There can be
no  assurance  that  the  Company  will   be  able  to  enter  into   additional
collaborative  arrangements  in  the  future  or  that  any  current  or  future
collaborative arrangements will result in successful product  commercialization.
To  the extent that agreements with corporate partners cover products to be sold
internationally,  such  sales  could  be  adversely  affected  by  governmental,
political   and  economic  conditions  in   other  countries,  including  tariff
regulations, taxes, import quotas and other factors.
 
    The  table  below  summarizes  certain  elements  of  the  Company's   major
collaborative  arrangements,  including  partners,  market  segments,  types  of
agreements and CIMA technology.

     product category may force the collaborative partner to alter its marketing
     plans, which could have a material adverse effect on the eventual marketing
     of the product.
(2)  As a result of  corporate restructuring due to  the sale of Sterling's  OTC
     business   to  SmithKline  Beecham,  SmithKline  Beecham  assumed  most  of
     Sterling's rights under this agreement, and certain rights with respect  to
     the U.S. and Canada reverted to the
     Company.  See "-- Agreements With  Corporate Partners -- SmithKline Beecham
     Option and Development Agreement."
 
     GLAXO AGREEMENT
 
    The Company has entered into a License and Development Agreement with  Glaxo
(the  "Glaxo Agreement") to produce an OraSolv  version of Zantac to be marketed
exclusively by  Glaxo in  the U.S.  and internationally,  for both  the OTC  and
prescription  markets. In  late 1995, the  FDA approved  the switch to  OTC of a
version of Zantac for heartburn indications  (Zantac 75). Pursuant to the  Glaxo
Agreement,  the Company will receive certain  fees to develop product prototypes
and all development costs will be borne by Glaxo. The Company will also  receive
payments  upon  completion  of  certain  milestones.  Glaxo  will  pay specified
royalties to  the Company  on net  sales of  the products.  The Glaxo  Agreement
provides that the
 
                                       23
<PAGE>
Company  retains  the right  to manufacture  certain  minimum quantities  of the
OraSolv products for the first five years following the first commercial sale of
the products. At any time during the term of the Glaxo Agreement, however, Glaxo
may  terminate  the  Company's  manufacturing  rights  for  specified   reasons.
Termination  of the  Company's manufacturing  rights or  of the  Glaxo Agreement
could have  a material  adverse  effect on  the  Company's business.  Timing  of
product  introductions under the Glaxo Agreement is within the control of Glaxo,
and the Company estimates that products developed under the Glaxo Agreement will
be introduced no earlier than the second half of 1998.
 
    SMITHKLINE BEECHAM LICENSE AGREEMENT
 
    The Company  entered into  a License  Agreement with  SmithKline Beecham  in
April  1996. The License Agreement grants SmithKline Beecham exclusive marketing
rights for certain specific OraSolv  OTC products. SmithKline Beecham will  have
the  right to market such products throughout  the world, except in the U.S. and
Canada. Under the  License Agreement,  the Company  will receive  a license  fee
which is refundable under certain circumstances, and is also entitled to receive
certain  milestone payments upon the occurrence of specified events. The Company
will also receive royalties on net sales of the products by SmithKline  Beecham.
SmithKline Beecham has a unilateral right to terminate the License Agreement for
any reason upon written notice to the Company within specified time periods. The
License  Agreement also contemplates  that the parties  will negotiate and enter
into a manufacturing and  supply agreement pursuant to  which the Company  would
manufacture and supply SmithKline Beecham with its requirements of the products.
There  can be no assurance, however, that  such an agreement will be reached or,
if reached, that such supply relationship will be profitable to the Company.  If
the  parties are unable  to agree upon  such manufacture and  supply terms, then
SmithKline Beecham  may  elect to  have  such products  manufactured  by  either
SmithKline Beecham or a third party manufacturer approved by the Company.
    SMITHKLINE BEECHAM OPTION AND DEVELOPMENT AGREEMENT
    The  Company entered into an Option  and Development Agreement with Sterling
Winthrop, Inc. ("Sterling") in May 1994. Subsequently, Sterling's worldwide  OTC
business   was  purchased  by  SmithKline   Beecham,  which  assumed  Sterling's
development and license option rights to all 15 products under the agreement for
markets outside the  U.S. and  Canada, but relinquished  rights to  five of  the
products  for sales  in the  U.S. and  Canada. The  agreement provides  that the
Company will develop a series of analgesic and cough/cold/flu, allergy and sinus
OraSolv products. The Company will receive  certain fees to develop a number  of
different  product prototypes for SmithKline Beecham's evaluation and will grant
to SmithKline Beecham,  upon payment  of additional specified  fees, options  to
enter  into  license  agreements  for  the  marketing  of  any  of  the products
developed. While this agreement describes the basic terms to be contained in any
license agreement subsequently entered into  between the Company and  SmithKline
Beecham,  SmithKline  Beecham  is not  obligated  to enter  into  any definitive
license agreement with  the Company  and generally has  the right  to abandon  a
product  at any time for any reason without significant penalty, or to terminate
the agreement entirely. If the Company does not enter into a definitive  license
agreement  with SmithKline Beecham  within a specified  time period, the Company
retains the right  to seek  an alternative  corporate partner  for the  products
being  developed,  although there  can be  no assurance  that the  Company could
locate a  suitable  alternative  corporate partner.  A  decision  by  SmithKline
Beecham  to  abandon  one  or more  products,  once  licensed,  could materially
adversely affect the Company's financial condition and results of operations.
 
    The agreement with SmithKline Beecham  specifies certain products for  which
any  license granted would be co-exclusive, permitting the Company to enter into
another collaborative  arrangement  with  a  different  corporate  partner  with
respect  to each  such product. As  to the  other products to  be developed, the
license granted to SmithKline Beecham would be exclusive. The agreement provides
that if any  definitive license  agreement is  entered into,  the Company  would
receive  certain license fees and a royalty on net sales of each of the products
subject to the license  agreement. While the  SmithKline Beecham agreement  does
not  specify  the terms  of any  manufacture and  supply agreement,  the Company
intends to negotiate to retain the right to manufacture the licensed products in
connection with any definitive license agreement entered
 
                                       24
<PAGE>
into with SmithKline Beecham.  There can be no  assurance that the Company  will
retain  manufacturing rights or that any such rights retained will be profitable
for the Company. The failure by the Company to retain manufacturing rights could
have a material adverse effect on the Company's profitability.
 
    OTHER ORASOLV AGREEMENTS
 
    In the first  quarter of  1996, the  Company entered  into three  additional
agreements  with  three undisclosed  multinational pharmaceutical  companies for
development or  manufacture of  OraSolv products.  Because the  marketplace  for
pharmaceutical  products  is  highly competitive,  disclosure  of  the potential
partner and market category or product may result in the prior implementation of
competitive strategies which would be  damaging or destructive to the  marketing
plans  of the potential partner. That activity could result in the loss of brand
equity and the  nonrecovery of  substantial advertising  and promotional  costs.
Accordingly,  at the present time both the identities of the other companies and
the nature of the products involved remain confidential.
 
    One of these agreements, a  full-scale stability, manufacturing and  testing
agreement,  provides  for the  Company  to conduct  stability  manufacturing and
testing of an OraSolv formulation of a certain class of pharmaceutical products.
The agreement  provides for  the partner  to pay  the Company  certain fees  and
provides  the partner an exclusive negotiation period for additional rights with
respect to the specific class of pharmaceutical products being evaluated by  the
partner.
 
    Under  the  other two  confidential  agreements, the  Company  is developing
prototypes of products formulated with the OraSolv technology for that partner's
evaluation. In exchange,  the partner will  make certain payments  to CIMA.  The
agreements  also  provide for  an  exclusive negotiation  period  for additional
rights with respect to the product.
 
    There can be  no assurance that  the potential partners  under any of  these
confidential  agreements  will  perform as  anticipated,  or that  any  of these
confidential agreements will  result in  the commercialization  of products.  In
addition,  each  of these  three confidential  agreements permit  the respective
potential partner to terminate the agreement at any time.
 
    MERCK AGREEMENT
 
    The Company has a  license agreement and supply  agreement with Merck  under
which  the Company  has developed  an AutoLution  (liquid effervescent)  form of
Pepcid AC, the OTC  version of Pepcid, Merck's  anti-ulcer product. The  license
agreement  provides that the Company will receive  a royalty on net sales of the
product, which Merck plans  to sell in Europe.  Merck may terminate the  license
agreement upon 90 days' written notice for any reason.
 
PATENTS AND PROPRIETARY RIGHTS
 
    The  Company actively seeks,  when appropriate, protection  for its products
and proprietary information by means of U.S. and foreign patents, trademarks and
contractual arrangements. In addition, the Company relies upon trade secrets and
contractual arrangements to protect certain  of its proprietary information  and
products.  The Company holds five U.S. patents. The most significant U.S. patent
issued  to  the  Company   covers  the  taste-masking,  microencapsulation   and
quick-dissolving  excipient technology incorporated in the OraSolv products. The
OraSolv patent and two others were issued in 1993 and expire in 2010, the fourth
patent was issued in 1995 and expires in 2012 and the fifth patent was issued in
1996 and  expires  in  2013. Two  of  the  issued U.S.  patents  relate  to  the
production  of  compressed  effervescent and  non-effervescent  tablets  using a
particular lubricant  developed by  the Company.  Another patent  relates to  an
effervescent  pediatric vitamin and mineral supplement. The fifth patent relates
to the formulation of a base coated acid effervescent mixture manufactured by  a
controlled  acid-base  reaction.  The  obtained  mixture  can  be  used  in  the
formulation of  acid  sensitive  compounds  with  OraSolv  technology  or  other
effervescent-based products.
 
    The  Company  holds two  patents  in Australia,  which  issued in  1990. The
Company also has a total of nine U.S. and foreign patent applications, including
two European Patent Office filings.
 
                                       25
<PAGE>
    The Company's  success will  depend in  part on  its ability  to obtain  and
maintain  patent protection for its products  and preserve its trade secrets. No
assurance can be given, however, that the Company's patent applications will  be
approved  or that any issued patents will provide competitive advantages for its
products or will not be challenged or circumvented by competitors.
    The ability  to commercialize  the  Company's products  will depend  on  not
infringing the patents of others. Although the Company is not aware of any claim
of  patent infringement  against it,  the Company  has entered  into a licensing
agreement with  Beecham  Group  plc  ("Beecham") to  avoid  the  possibility  of
litigation.  Under  the  license,  the Company  has  a  non-exclusive, worldwide
license to make, have made, use and  sell products covered by a particular  U.S.
patent  issued  to  Beecham and  corresponding  rights in  other  countries (the
"Beecham Patent Rights"), which  may cover certain  OraSolv products. Under  the
terms  of the license, the Company is required to pay a royalty of 2% of amounts
received by the Company in respect of OraSolv products. The license extends  for
the  life of the Beecham Patent Rights  and is terminable upon default by either
party.
 
    Whether or  not  the  outcome  of  any  litigation  concerning  patents  and
proprietary  technologies  is  favorable  to  the  Company,  the  cost  of  such
litigation and the diversion of  the Company's resources during such  litigation
could have a material adverse effect on the Company.
 
    Much of the Company's technology is dependent upon the knowledge, experience
and  skills of key scientific and technical  personnel. To protect rights to its
proprietary know-how and technology, Company  policy requires all employees  and
consultants  to execute confidentiality agreements  that prohibit the disclosure
of confidential information to anyone outside the Company. These agreements also
require disclosure and assignment to  the Company of discoveries and  inventions
made  by  such persons  while devoted  to  Company activities.  There can  be no
assurance that these agreements will not be breached, that the Company will have
adequate remedies for any such breach  or that the Company's trade secrets  will
not  otherwise become  known or  be independently  developed by  competitors. In
addition, it is possible others may infringe the patent rights of the Company.
 
    The Company may desire  or be required to  obtain licenses from others  with
respect  to materials used in the Company's products or manufacturing processes,
including drug coating techniques. There can be no assurance that such  licenses
will  be obtainable  on commercially  reasonable terms, if  at all,  or that any
licensed patents or proprietary rights will be valid and enforceable.
 
MANUFACTURING
 
    A key component of the Company's strategy is to be the primary  manufacturer
of  OraSolv products.  Advantages of  this strategy  include the  control of the
technology, the  ability  to quickly  increase  production, and  to  refine  the
production  process  as  necessary  to rapidly  and  successfully  bring OraSolv
products to market.  Although the OraSolv  process uses standard  pharmaceutical
production  equipment, certain modifications were  required to meet the specific
needs of  OraSolv products,  including the  need for  producing softer  tablets,
special  protective packaging and dehumidification.  During the refining process
and the process validation runs, the Company identified the key product  quality
issues,  which the  Company has now  built into the  product specifications. The
Company believes that this manufacturing  experience gives it an advantage  over
its  competitors. The Company  believes that its  ability to manufacture OraSolv
products  provides  economies  of  scale,  therefore  making  the  Company  more
attractive  to  its partners  by  allowing them  access  to smaller  volume line
extensions without making significant capital investments.
 
    The Company's  OraSolv  production  facility is  located  in  Eden  Prairie,
Minnesota,  which also houses the  Company's corporate headquarters. The Company
began occupying and making  leasehold improvements to the  new facility in  late
June  1994 and the facility was completed in December 1994. See "-- Properties."
Initially, the Company will operate one  production line at this facility  which
it  believes  will be  capable  of producing  400  million tablets  a  year. The
facility is  designed to  be expandable  to six  production lines  to achieve  a
maximum  capacity  of  2.4  billion tablets  a  year.  The  production equipment
consists of  an  integrated blending,  tableting  and packaging  operation.  The
configuration of the production flow layout and this
 
                                       26
<PAGE>
equipment  has been designed by Company personnel and the Company's consultants.
Most of the  equipment consists  of components commonly  used in  pharmaceutical
manufacturing.  Modern  technology for  environmental  control is  utilized. The
equipment was selected for ease of  operation, cleaning and changeover and  cost
effectiveness.  The production line is capable of packaging a variety of package
designs with rapid conversion between sizes.
 
    During 1995,  the  facility  was  validated, registered  with  the  FDA  and
licensed by the State of Minnesota. Numerous site audits by major pharmaceutical
companies  have also  successfully occurred.  After the  completion of equipment
validation, CIMA successfully  conducted full  scale-up runs  of the  production
line.  To  date, over  50 production  batches have  been manufactured  using the
OraSolv production equipment.
 
    The  OraSolv   production  process   begins  with   the  purchase   of   the
pharmaceutical  ingredients to be used in manufacturing the products. The active
drug ingredients may be shipped to coating materials suppliers where appropriate
coating materials  are  applied to  microencapsulate  the ingredients.  In  some
cases,  the  Company purchases  the microencapsulated  active ingredient  from a
supplier. These coating materials suppliers are subject to extensive  government
regulation,  including current Good  Manufacturing Practice regulations ("cGMP")
promulgated by the FDA. After coating,  the active drug ingredients are sent  to
the  Company where  they are tested  again by CIMA's  Analytical Quality Control
group and released to  the production department. The  active and inactive  drug
ingredients  that have been  quality control released  are further processed and
pressed into  OraSolv  tablets. The  tablets  are immediately  transferred  into
blister-foil  packages  and  packed  in  cartons  in  a  high-speed,  continuous
operation. The  pharmaceutical ingredients  and  other supplies  to be  used  in
manufacturing  OraSolv products  are standard  pharmaceutical products available
from numerous suppliers. Most coating materials are also available from numerous
suppliers. In some instances, however,  certain coating materials or  techniques
may  be available only from a single  supplier. If any such coating materials or
techniques were to  become unavailable, the  Company believes that  satisfactory
alternative  materials or techniques could be substituted. However, there can be
no assurance that the Company's manufacturing operations would not be disrupted.
Any such disruption could have an  adverse effect on the Company's business  and
could possibly damage relations with its corporate partners.
 
    By  producing many  full-scale trial  batches, the  Company believes  it has
identified  and  minimized   potential  problems  that   could  affect   product
manufacturing in commercial quantities. There can be no assurance, however, that
manufacturing  and  control  problems  will  not  arise  as  the  Company begins
manufacturing at commercial  scale. If manufacturing  or control problems  arise
and are not corrected for any reason, the Company's business could be materially
adversely affected.
 
MARKETING
 
    The  Company's marketing strategy  is to rely on  its corporate partners for
the marketing and sale of its products. The Company believes this strategy  will
enable  it to respond quickly  to market demands, while  avoiding the effort and
expense associated with the establishment  of an end-user marketing  capability.
The  Company's  internal  marketing  department  has  focused  on  promoting the
benefits of OraSolv to its corporate pharmaceutical partners and with conducting
consumer  surveys  and  physician  research  of  various  OraSolv  formulations.
Currently,  the Company  has entered  into corporate  collaborations with Glaxo,
Merck  and  SmithKline  Beecham,  and  with  three  other  major  pharmaceutical
companies.
 
RESEARCH AND DEVELOPMENT
 
    The research and development ("R&D") department at CIMA is primarily focused
on  the development of oral dosage forms based on CIMA proprietary technologies.
These efforts are conducted  to support the CIMA  strategic and business  goals.
The  Company's R&D  department is  devoted to  the development  of drug delivery
technologies and dosage forms for pharmaceutical applications. The key goals for
the R&D team  are: develop  innovative drug  delivery systems  that fulfill  the
pharmaceutical  partners' needs and  meet the strategy  of the Company; develop,
expand and support  systems required  to fulfill cGMP  production at  commercial
levels  necessary to  meet the  requirements of  major pharmaceutical companies;
recruit and train high quality  technical and scientific personnel; and  support
the Company's intellectual property process.

    The  R&D  department includes  scientists  recruited from  the  research and
development  groups  of  major  U.S.  pharmaceutical  companies.  Currently  R&D
personnel  and  support  systems  and  facilities  are  organized  in  a  way to
effectively develop formulations from bench scale through full  scale/commercial
size.  Such development is carried  out at the R&D  facilities in Brooklyn Park,
Minnesota and  in  the  full  scale  manufacturing  facility  in  Eden  Prairie,
Minnesota.  The Company believes that its  R&D facilities are in compliance with
cGMP. In  both facilities,  small cGMP  batches are  manufactured, packaged  and
released  to support initial studies in  humans, including both consumer studies
for OTC products and clinical studies for prescription products.
 
    During the three years  ended December 31,  1995, CIMA's total  expenditures
for  research  and  development  were  $1,856,900,  $3,548,900  and  $6,504,500,
respectively, of which amounts research and development fees from the  Company's
collaborative partners were $271,800, $452,900 and $496,600, respectively.
 
COMPETITION
 
    Competition  in  the  areas  of pharmaceutical  products  and  drug delivery
systems is  intense.  The  Company's  primary competitors  in  the  business  of
developing  and  applying drug  delivery  systems include  companies  which have
substantially  greater  financial,   technological,  marketing,  personnel   and
research and development resources than the Company. The Company's products will
compete not only with products employing advanced drug delivery systems but also
with   products  employing  conventional  dosage  forms.  New  drugs  or  future
developments in alternative drug  delivery technologies may provide  therapeutic
or  cost  advantages over  the  Company's potential  products.  There can  be no
assurance that developments by others will not render the Company's products  or
technologies noncompetitive or obsolete.
 
    Among  the technologies  expected to  provide competition  for the Company's
OraSolv technology is the Zydis technology developed by R.P. Scherer Corporation
("Scherer") and the Shearform Matrix technology developed by Fuisz Technologies,
Ltd. ("Fuisz"). The  Zydis technology  is a fast-dissolving  oral drug  delivery
system  based on a freeze-dried gelatin  tablet. The Shearform Matrix technology
has application to  two tablet formats,  one of which  involves waterless,  fast
dissolving oral delivery which Fuisz calls "FlashDose."
 
    The  principal competitive factors in the market for rapid dissolving tablet
technologies are compatibility with  taste-masking techniques, dosage  capacity,
drug compatibility, cost and ease of manufacture and required capital investment
for  manufacturing.  The  Company  believes  that  its  rapid  dissolving tablet
technology competes  favorably  with respect  to  these factors.  However,  both
Scherer  and Fuisz  have been  successful in  licensing their  technologies to a
number of  pharmaceutical  companies. The  Company  also believes  that  certain
pharmaceutical  companies  may  be  developing  other  rapid  dissolving  tablet
technologies which might be competitive with the Company's technology.
 
GOVERNMENT REGULATION
 
    All pharmaceutical  manufacturers are  subject  to extensive  regulation  of
their   activities,  including  research  and  development  and  production  and
marketing, by numerous governmental authorities in the U.S. and other countries.
In the U.S., pharmaceutical products are  subject to rigorous regulation by  the
FDA.  The federal Food, Drug, and Cosmetic  Act, as amended, and the regulations
promulgated thereunder, and  other federal and  state statutes and  regulations,
govern,  among other  things, the  research, development,  testing, manufacture,
storage, recordkeeping, labeling, advertising  and promotion, and marketing  and
distribution  of  pharmaceutical products.  If a  company  fails to  comply with
applicable requirements,  it  may be  subject  to administrative  or  judicially
imposed  sanctions such as civil penalties, criminal prosecution of the company,
its officers and employees, injunctions,  product seizure or detention,  product
recalls,  total or partial  suspension of production and  FDA refusal to approve
pending premarket approval applications or supplements to approved applications.
 
    In general,  FDA approval  is required  before  a new  drug product  may  be
marketed  in the U.S. However, most OTC  drug products are exempt from the FDA's
premarketing approval requirements. In 1972, the FDA instituted the ongoing  OTC
Drug  Review in order to evaluate the  safety and effectiveness of all OTC drugs
then on  the  market.  Through the  OTC  Drug  Review process,  the  FDA  issues
monographs that set forth the specific active ingredients, dosages, indications,
and labeling statements for OTC drugs that the
 
                                       28
<PAGE>
FDA  will consider generally recognized as  safe and effective and therefore not
subject to premarket approval. For certain  categories of OTC drug products  not
yet  subject to  a final  monograph, the  FDA usually  will not  take regulatory
action against such a product unless failure  to do so poses a potential  health
hazard  to  consumers.  The  Company initially  intends  to  emphasize  OTC drug
products that generally do not require  FDA approval. Products subject to  final
monographs,  however,  are  subject to  various  FDA regulations  such  as those
outlining cGMP  requirements, general  and  specific OTC  labeling  requirements
(including   warning  statements),  the   restriction  against  advertising  for
conditions other than those stated in product labeling, and the requirement that
OTC  drugs  contain  only  suitable  inactive  ingredients.  OTC  products   and
manufacturing  facilities are subject  to FDA inspection,  and failure to comply
with applicable regulatory requirements may lead to administrative or judicially
imposed penalties.
 
    Future marketing of  products not  formulated in compliance  with final  OTC
drug  monographs typically will require a formal  submission to the FDA, such as
an Abbreviated New Drug  Application ("ANDA"), New  Drug Application ("NDA")  or
Supplement  to existing New Drug Application  ("SNDA"), and ultimate approval by
the FDA.  This  application and  approval  process  can be  expensive  and  time
consuming,  typically  taking  from six  months  to several  years  to complete.
Further, there can be no assurance that  approvals can be obtained, or that  any
such  approvals will be on the terms  or have the scope necessary for successful
commercialization of these products. The  Company expects that any required  FDA
approvals  in connection with the introduction of new, non-monographed products,
such as an OraSolv version of Zantac, would be sought by the Company's corporate
partners. Marketing of such  products could be delayed  or prevented because  of
this  process. Even after an  ANDA, NDA or SNDA  has been approved, existing FDA
procedures may delay initial product shipment. Delays caused by the FDA approval
process may materially  reduce the  period during  which there  is an  exclusive
right  to exploit  patented products or  technologies. Even if  any required FDA
approval has  been  obtained  with  respect to  a  product,  foreign  regulatory
approval  of  a  product  must  be  obtained  prior  to  marketing  the  product
internationally. Foreign approval  procedures vary from  country to country  and
the  time required for  approval may result  in delays in  or ultimately prevent
marketing. The Company expects to rely on its pharmaceutical company partners to
obtain any necessary government approvals in foreign countries.
 
    Prescription drug products with proven  safety and efficacy profiles may  be
"switched" to OTC status through the submission to and approval by the FDA of an
NDA. The information and data required to support a switch application vary with
individual  drugs. In  some cases, the  manufacturer may be  required to conduct
clinical investigations or  other scientific  studies to assess  the safety  and
effectiveness  of the  drug for OTC  use. In  evaluating an OTC  switch, the FDA
considers whether the  drug product  is safe for  use by  consumers without  the
supervision  of an appropriate licensed healthcare professional. As prescription
drug products are switched to the OTC market, pharmaceutical companies face  the
same challenges to establish brand identification and product differentiation as
they  face with current OTC drug products. Although switched products in certain
cases may be  eligible for  a three-year  period of  market exclusivity  (during
which  time the FDA will not consider any  ANDAs for the same drug), the Company
believes that its OraSolv drug delivery  system can help its corporate  partners
differentiate  their  products  during  any exclusivity  period  and  maintain a
competitive advantage thereafter.
 
    If a generic version of a drug  already approved under an NDA and no  longer
subject  to  any FDA  marketing exclusivity,  is  bioequivalent to  the approved
product, preparation  and  submission of  an  ANDA will  be  the most  time  and
cost-effective  approach  to the  FDA  premarket approval.  The  methodology for
establishing bioequivalence through in vitro or in vivo methods is viewed to  be
straightforward.  Because  CIMA's taste-masking  systems  are used  in immediate
release dosage forms, this approach is generally the most expeditious.
 
    Certain drugs may  raise distinctive  issues, such as  a need  for a  unique
approach  to proving  bioequivalence. In  those cases,  premarket approval under
section 505(b)(2) of the Food, Drug, and Cosmetic Act would be more appropriate.
Section 505(b)(2) allows the FDA to  approve an NDA using shortened  procedures,
usually  for drugs that have proven safety profiles because of their marketplace
performance among  a  large population  group.  In a  505(b)(2)  application,  a
company may rely on clinical investigations conducted by others to which it does
not  hold a right of reference. In general, a 505(b)(2) application is supported
by two or three clinical studies  among the target population group designed  to
verify the safety
 
                                       29
<PAGE>
and  efficacy of the drug  product in that population  using the target dose and
dose sequence. The cost  of this approach,  which is generally  used when a  new
delivery system or indication is added to an existing drug product, is typically
much less that a standard NDA.
 
    Each  domestic drug product  manufacturing facility must  be registered with
the FDA. Each manufacturer must inform the  FDA of every drug product it has  in
commercial  distribution  and  keep such  list  updated.  Domestic manufacturing
facilities are  also subject  to at  least biannual  inspection by  the FDA  for
compliance  with cGMP regulations. Compliance with cGMP is required at all times
during  the  manufacture  and  processing  of  drug  products.  CIMA's  existing
manufacturing  facilities have been inspected periodically by the FDA. While the
Company's new OraSolv manufacturing facility  is required to be registered  with
the  FDA and to comply with cGMP regulations at all times, FDA approval will not
be required prior to commencement of manufacturing of OTC drug products. An  FDA
inspection of the premises once manufacturing has been initiated is very likely.
Even  though the  Company has  worked diligently  to assure  compliance with FDA
regulations and has  been audited  by the quality  control/compliance groups  of
several  of  its  current and  potential  corporate  partners, there  can  be no
guarantee that  FDA  inspections  will proceed  without  any  compliance  issues
requiring  the  expenditure of  money and  resources  to resolve.  The Company's
facilities have been inspected  by and the Company  has received a license  from
the Minnesota Board of Pharmacy to manufacture drug products in its facilities.
 
    The  Company is also  subject to regulation under  various federal and state
laws  regarding,  among   other  things,   occupational  safety,   environmental
protection,  hazardous substance control and  product advertising and promotion.
In  connection   with  its   research  and   development  activities   and   its
manufacturing,  the Company is subject to  federal, state and local laws, rules,
regulations and policies  governing the use,  generation, manufacture,  storage,
air emission, effluent discharge, handling and disposal of certain materials and
wastes.  The  Company  believes  that  it  has  complied  with  these  laws  and
regulations in all material respects  and it has not  been required to take  any
action  to correct  any material noncompliance.  The Company  does not currently
anticipate that any material capital expenditures  will be required in order  to
comply  with federal, state and local environmental laws or that compliance with
such laws will have a material effect on the earnings or competitive position of
the Company.  The Company  is unable  to  predict, however,  the impact  on  the
Company's  business of any changes in such environmental laws or of any new laws
or regulations that may be imposed in  the future and there can be no  assurance
that  the Company will not be required  to incur significant compliance costs or
be held  liable  for  damages  resulting  from  violations  of  these  laws  and
regulations.  The  Company has  manufactured an  herbicide  product for  a large
chemical company  involving  certain  hazardous  materials  and  chemicals.  The
herbicide  product was manufactured in a separate facility from the Eden Prairie
facility. The  Company believes  that  its safety  procedures for  handling  and
disposing  of such  materials and  chemicals complied  with the  requirements of
federal and state law.
 
PROPERTIES
 
    The Company  has leased  a  75,000 square  foot  facility in  Eden  Prairie,
Minnesota,  a suburb of Minneapolis, which houses its corporate headquarters and
has been prepared for use as an  OraSolv production facility. This lease has  an
initial  term of ten years with minimum  annual base rent payments (exclusive of
real estate taxes and  maintenance fees) of  approximately $337,500 through  the
third  year, $375,000 for years four through  seven and $412,500 for years eight
through ten of the lease.  The Company has the option  to extend the lease  term
for  an  additional  seventy months  with  a  minimum annual  base  rent payment
(exclusive of real estate taxes and maintenance fees) of approximately $450,000.
 
    In addition to its new OraSolv production facility, the Company also  leases
32,000  square feet located  in an industrial park  in Brooklyn Park, Minnesota.
The Brooklyn Park facility contains offices as well as research and  development
and  certain other pilot development and manufacturing operations. The lease for
this facility  expires in  September 1998  and is  renewable for  an  additional
three-year  period  and  two  five-year  periods.  The  Company  currently  pays
approximately $144,600 in annual base rent  (exclusive of real estate taxes  and
maintenance  fees)  under this  lease.  The Company's  non-OraSolv manufacturing
operations, including AutoLution, are located in the Brooklyn Park facility. The
Company  believes  that  its  facilities  are  adequate  for  its  current   and
anticipated   future  operations  and  that  any  necessary  lease  renewals  or
additional leased space could be obtained on commercially reasonable terms.
 
                                       30

EMPLOYEES
 
    On March 31, 1996, the Company had  49 full-time employees, of whom 12  were
engaged   in  research  and  development  (including   5  with  Ph.D.s),  17  in
manufacturing, 7 in compliance, 3 in  quality control and 10 in  administration,
business  development,  finance  and  human  resources.  Most  of  the Company's
scientific  and   engineering  employees   have   had  prior   experience   with
pharmaceutical  or medical products  companies. No employee  is represented by a
union, and  the Company  has  never experienced  a  work stoppage.  The  Company
believes its employee relations are good.
 
    The  success of  the Company  and of its  business strategy  is dependent in
large part on the ability  of the Company to  attract and retain key  management
and  operating  personnel. Such  individuals are  in high  demand and  are often
subject to competing offers. In  particular, the Company's success will  depend,
in  part, on  its ability to  attract and  retain the services  of its executive
officers and scientific and technical personnel. The loss of the services of one
or more  members  of  management or  key  employees  or the  inability  to  hire
additional  personnel  as  needed may  have  a  material adverse  effect  on the
Company. The Company currently has no full-time chief financial officer, but  is
actively recruiting to fill this position.
 
LIABILITY INSURANCE
 
    The  Company's  business involves  exposure  to potential  product liability
risks that  are inherent  in the  production and  manufacture of  pharmaceutical
products.  Although the Company has not experienced any product liability claims
to date, any such claims  could have a material  adverse impact on the  Company.
The  Company  currently has  general liability  insurance and  product liability
insurance with coverage limits of $5,000,000 per occurrence and $5,000,000 on an
annual aggregate basis. The Company's  insurance policies provide coverage on  a
claims  made basis and are subject to annual renewal. There can be no assurance,
however, that the Company will be able to maintain such insurance on  acceptable
terms  or that  the Company  will be  able to  secure increased  coverage as the
commercialization of its products  proceeds or that  any insurance will  provide
adequate protection against potential liabilities.

    The Board has an Audit Committee which consists of Messrs. Ratoff and Musket
and Dr.  Weisbach. The  Audit Committee  reviews the  results and  scope of  the
annual  audit and other services provided  by the Company's independent auditors
as well  as the  Company's  accounting principles  and  its system  of  internal
controls,  and reports the results of these reviews to management and the Board.
The Audit Committee also meets with the Company's independent auditors at  least
once  annually  to review  the results  of  the annual  audit and  discusses the
financial statements, recommends  to the  Board the independent  auditors to  be
retained  and receives and  considers the accountants'  comments as to controls,
adequacy of staff and management  performance and procedures in connection  with
audit and financial controls.
 
    The Compensation Committee (i) determines the amount of compensation for the
Chief   Executive   Officer  and   President  of   the  Company,   (ii)  reviews
recommendations of the Chief Executive  Officer concerning compensation for  the
other  executive officers  and incentive compensation,  including stock options,
for the other employees of the Company, subject to ratification by the Board and
(iii) otherwise administers the Company's  stock option plans. The  Compensation
Committee  is currently composed of two  non-employee directors: Mr. Glarner and
Dr. Weisbach.  Prior to  July 1,  1995,  when Dr.  Siebert became  an  executive
officer of the Company, Dr. Siebert also served on the Compensation Committee.
 
    Directors  are elected annually  and its members hold  office until the next
annual meeting of stockholders  or until their successors  are duly elected  and
qualified, or until their earlier removal or resignation. Executive officers are
elected  by  the Board.  There  are no  family  relationships among  any  of the
directors and executive officers of the Company.
 
DIRECTOR COMPENSATION
 
    Each non-employee director of the Company  is entitled to receive an  annual
fee  of $5,000, payable quarterly, a per  meeting fee of $2,500 for each meeting
(including telephonic  meetings)  of the  Board  attended by  such  non-employee
director  and a per meeting fee of $1,250 for each meeting of (i) a committee of
the Board  not held  in  connection with  a regular  Board  meeting or  (ii)  an
operating  committee of the Company, in  each case attended by such non-employee
director; provided, however, that the aggregate
 
                                       33
<PAGE>
amount of fees paid shall  not exceed $20,000 (excluding expense  reimbursement)
per  director per year.  In the fiscal  year ended December  31, 1995, the total
compensation paid  to non-employee  directors was  $62,500. The  members of  the
Board are also eligible for reimbursement for their reasonable expenses incurred
in  connection  with attendance  at Board  meetings  in accordance  with Company
policy. Messrs.  Glarner  and Musket  are  currently voluntarily  foregoing  the
payment of any fees.
 
    Each  non-employee director of the Company also receives stock option grants
under the  1994  Directors' Stock  Option  Plan (the  "Directors'  Plan").  Only
directors of the Company who are not employees of the Company or a subsidiary of
the Company are eligible to receive grants of options under the Directors' Plan.
Options  granted under the  Directors' Plan are  intended by the  Company not to
qualify as incentive stock options under the Code.
 
    Option grants under the Directors' Plan are non-discretionary. On the  first
business  day  immediately following  the annual  stockholders' meeting  of each
year, each member of the Company's Board  who is not an employee of the  Company
is  automatically granted under  the Directors' Plan,  without further action by
the Company, the Board or the stockholders of the Company, an option to purchase
7,500 shares of Common Stock of the Company. In addition, each new  non-employee
director will receive an option to purchase 20,000 shares of Common Stock of the
Company  on  the first  business day  following  the date  such new  director is
elected to the  Board. No other  options may be  granted at any  time under  the
Directors' Plan. The exercise price of options granted under the Directors' Plan
is  100% of the fair market  value of the Common Stock  subject to the option on
the date of the option grant. Options  granted pursuant to the initial grant  to
purchase  of  20,000 shares  of Common  Stock under  the Directors'  Plan become
exercisable as to 50% of  the option shares on  the 12-month anniversary of  the
date  of grant and the remainder  become exercisable on the 24-month anniversary
of the date of grant. Options granted  on the business day following the  annual
meeting  of stockholders become  fully exercisable six  months subsequent to the
date of grant.  The term of  options granted  under the Directors'  Plan is  ten
years.  In the event of a merger of the Company with or into another corporation
or a  consolidation,  reorganization, recapitalization,  stock  dividend,  stock
split,  or other change  in the corporate  structure, appropriate adjustments to
the Directors'  Plan and  the outstanding  options will  be made  so as  not  to
increase or decrease the option rights outstanding.
 
    During  the  year  ended  December 31,  1995,  the  Company  granted options
covering 7,500  shares  to each  non-employee  director  of the  Company  at  an
exercise  price per share of  $4.75 and an option  covering 20,000 shares to Mr.
Ratoff upon his election as a director at an exercise price per share of $5.625.
The fair market value of  such Common Stock on the  date of grant was $4.75  and
$5.625 per share, respectively (based on the closing sales price reported in the
Nasdaq  National Market for the date of grant). As of March 31, 1996, no options
had been exercised under the Directors' Plan.

                          DESCRIPTION OF CAPITAL STOCK
 
    The following description of  the capital stock of  the Company and  certain
provisions of the Company's Certificate of Incorporation and Bylaws is a summary
and  is  qualified in  its  entirety by  the  provisions of  the  Certificate of
Incorporation and Bylaws,  which have been  filed as exhibits  to the  Company's
Registration Statement, of which this Prospectus is a part.
 
    The authorized capital stock of the Company consists of 20,000,000 shares of
Common Stock, par value $.01 per share, and 5,000,000 shares of Preferred Stock,
par value $0.01 per share.
 
COMMON STOCK
 
    At  March 31, 1996  there were 7,840,099 shares  of Common Stock outstanding
and no shares of Preferred Stock outstanding.
 
    The holders of Common Stock are entitled to one vote for each share held  of
record  on all matters submitted  to a vote of  the stockholders. The holders of
Common Stock are not  entitled to cumulative voting  rights with respect to  the
election  of directors and, as a  consequence, minority stockholders will not be
able to elect directors on the basis of their votes alone.
 
    Subject to preferences that may be applicable to any then outstanding shares
of Preferred Stock, holders of Common Stock are entitled to receive ratably such
dividends as  may  be declared  by  the Board  out  of funds  legally  available
therefor.  See "Dividend  Policy." In the  event of  liquidation, dissolution or
winding up of the  Company, holders of  the Common Stock  are entitled to  share
ratably in all assets remaining after payment of liabilities and the liquidation
preference  of any then outstanding shares of Preferred Stock. Holders of Common
Stock have no preemptive rights and no right to convert their Common Stock  into
any  other  securities.  There  are no  redemption  or  sinking  fund provisions
applicable to the Common Stock. All outstanding shares of Common Stock are,  and
all  shares of Common Stock  to be outstanding upon  completion of this offering
will be, fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Board has the authority, without further action by the stockholders,  to
issue up to 5,000,000 shares of Preferred Stock in one or more series and to fix
the rights, preferences, privileges and restrictions thereof, including dividend
rights,  conversion  rights,  voting rights,  terms  of  redemption, liquidation
preferences, sinking fund terms and the number of shares constituting any series
or the designation of  such series, without  any further vote  or action by  the
stockholders.  The issuance of Preferred Stock could adversely affect the voting
power of  holders of  Common Stock  and the  likelihood that  such holders  will
receive  dividend payments and payments upon  liquidation may have the effect of
delaying, deferring or  preventing a  change in  control of  the Company,  which
could  have a  depressive effect  on the  market price  of the  Company's Common
Stock. The Company has no present plan to issue any shares of Preferred Stock.
 
OPTIONS AND WARRANTS
 
    As of  March 31,  1996, there  were outstanding  under the  Company's  stock
option  plans options  to purchase  an aggregate  of 1,215,334  shares of Common
Stock at exercise  prices ranging  from $2.80  to $10.13.  These options  expire
between August 17, 1997, and October 25, 2005.
 
    As  of  March  31,  1996  there were  outstanding  warrants  to  purchase an
aggregate of 106,467 shares of  Common Stock at an  exercise price of $6.00  per
share. Each warrant contains provisions for the adjustment of the exercise price
and  the aggregate number of shares issuable upon exercise of the warrants under
certain circumstances, including stock dividends, stock splits, reorganizations,
reclassifications, consolidations  and certain  dilutive sales  of common  stock
below  the  then  existing exercise  price.  All such  warrants  are exercisable
immediately and expire at various times through January 15, 1997.
 
REGISTRATION RIGHTS
 
   
    Following the offering, holders  of the warrants  described in the  previous
paragraph,  representing 106,467 shares  of the Common  Stock (collectively, the
"Registrable  Securities"),  have  registration   rights  pursuant  to   various
agreements  with the  Company. All such  holders of  Registrable Securities have
waived their registration rights in  connection with this offering. Under  these
agreements,  if the Company proposes to register any of its securities under the
Securities Act, holders of the  Registrable Securities are entitled, subject  to
certain  restrictions and exceptions, to include their Registrable Securities in
such registration. The  underwriters of  any such  offering have  the right,  in
certain circumstances and subject to certain conditions,
    
 
                                       42
<PAGE>
to  limit the number of shares included in the offering. The Company is required
to  bear  all  registration  and  selling  expenses  (other  than  underwriters'
discounts and commissions) in such offering. In addition, under the registration
rights  agreements, holders of Registrable Securities are entitled under certain
circumstances to  demand  that  the  Company prepare  and  file  a  registration
statement under the Securities Act at its expense and require the Company to use
its  best efforts to effect such registration, subject to certain conditions and
limitations. Finally, holders of Registrable Securities may require the  Company
to  file  additional registration  statements on  Form  S-3, subject  to certain
conditions and limitations.
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS
 
    The Company is subject to the provisions of Section 203 of the Delaware Law,
an anti-takeover law. In general, the statute prohibits a publicly-held Delaware
corporation from  engaging  in  a "business  combination"  with  an  "interested
stockholder"  for a period of  three years after the  date of the transaction in
which  the  person  became  an  interested  stockholder,  unless  the   business
combination  is  approved  in  a  prescribed  manner.  A  "business combination"
includes a merger,  asset sale  or other  transaction resulting  in a  financial
benefit  to  the  stockholder.  For  purposes  of  Section  203,  an "interested
stockholder" is a person who, together with affiliates and associates, owns  (or
within  three years  prior, did  own) 15%  or more  of the  corporation's voting
stock.
 
    The Company's Bylaws provide that each  director is to be elected  annually.
Candidates  for  directors  shall  be  nominated  only  by  the  Board  or  by a
stockholder who gives written notice to the Company at least 30 days but no more
than 90  days before  the  annual meeting.  In  addition, the  Company's  Bylaws
provide  that any business conducted at the annual meeting of stockholders shall
be brought before the meeting by the  Board in compliance with Rule 14a-8  under
the  Securities Exchange Act of 1934 or by a stockholder of record who gives not
less than 30  nor more than  90 days prior  written notice to  the Company.  The
Company may have such number of directors as determined from time to time by the
Board,  which currently consists  of six members.  Between stockholder meetings,
the Board  may  appoint  new  directors  to  fill  vacancies  or  newly  created
directorships.  The  Certificate  does  not  provide  for  cumulative  voting at
stockholder meetings for  election of directors.  Stockholders controlling  more
than  50% of  the outstanding  Common Stock  can elect  the entire  Board, while
stockholders controlling 49% of the outstanding Common Stock may not be able  to
elect any directors. A director may be removed from office only for cause by the
affirmative  vote  of  a majority  of  the  combined voting  power  of  the then
outstanding shares  of stock  entitled  to vote  generally  in the  election  of
directors.
 
    The  Company's Bylaws also  provide that the  authorized number of directors
may be changed only by resolution of  the Board. Delaware Law and these  charter
provisions  may  have  the effect  of  deterring hostile  takeovers  or delaying
changes in control or management of  the Company, which could have a  depressive
effect on the market price of the Company's Common Stock.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
    The  Company's Certificate  of Incorporation  provides that,  to the fullest
extent permitted  under Delaware  Law, a  director of  the Company  will not  be
liable  to the Company  or its stockholders  for monetary damages  for breach of
fiduciary duty as a director.  These provisions eliminate a director's  personal
liability for monetary damages resulting from a breach of fiduciary duty, except
in  certain circumstances involving  certain wrongful acts, such  as (i) for any
breach of the  director's duty of  loyalty to the  Company or its  stockholders,
(ii)  for  acts or  omissions not  in  good faith  or which  involve intentional
misconduct or  a  knowing violation  of  law, (iii)  under  Section 174  of  the
Delaware  Law, or (iv)  for any transaction  from which the  director derives an
improper personal benefit. These provisions do not limit or eliminate the rights
of the  Company or  any stockholder  to  seek non-monetary  relief, such  as  an
injunction or rescission, in the event of a breach of director's fiduciary duty.
These  provisions will not alter a  directors liability under federal securities
laws. The Company's  Bylaws also contain  provisions indemnifying the  directors
and officers of the Company to the fullest extent permitted by the Delaware Law.
The Company believes that these provisions will assist the Company in attracting
and retaining qualified individuals to serve as directors.

    The  transfer agent  and registrar  for the Common  Stock of  the Company is

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon completion of this offering, based on the number of shares  outstanding
as  of  March  31, 1996,  the  Company  will have  outstanding  an  aggregate of
8,840,099 shares of Common Stock (9,255,195 if the Underwriters'  over-allotment
option is exercised in full), of which 2,800,000 shares are being offered hereby
and  of which all but 15,027 shares of  Common Stock will be freely tradeable in
the public market, subject in certain  cases to lock-up agreements as  described
below. Certain volume resale restrictions are imposed by the Securities Act with
respect  to 15,027 shares  of Common Stock  referenced above, which restrictions
will expire in January 1997; however, such 15,027 shares have been registered on
a Form S-3 registration statement and may be sold without such restrictions.
    
 
    In general, under  Rule 144  as currently in  effect, a  person (or  persons
whose  shares are aggregated) who has beneficially owned "restricted securities"
(as such term is defined in Rule 144) for at least two years, including a person
who may be deemed an  affiliate of the Company, is  entitled to sell within  any
three  month period a number of shares of  Common Stock that does not exceed the
greater of 1% of the then outstanding shares of Common Stock of the Company  and
the  average weekly trading  volume of the  Common Stock on  the Nasdaq National
Market during the four calendar weeks preceding such sale. Sales under Rule  144
are  further subject  to certain  restrictions relating  to the  manner of sale,
notice and the availability of current  public information about the Company.  A
person  who is not  an affiliate of the  Company at any time  during the 90 days
preceding a sale and who  has beneficially owned shares  of Common Stock for  at
least  three years, is entitled to sell such shares without regard to the volume
limitations, manner of  sale provisions,  notice or other  requirements of  Rule
144.  However,  the transfer  agent may  require  an opinion  of counsel  that a
proposed sale of shares comes within the terms of Rule 144 prior to effecting  a
transfer  of such shares. Such opinion, if  appropriate, will be provided at the
expense of the Company.
 
    In addition,  under the  Company's Equity  Incentive Plan,  the Company  has
issued options to purchase Common Stock at prices which are below current market
and  may issue  options to  purchase additional  shares of  Common Stock  in the
future. At March 31, 1996, options to purchase 1,050,334 shares of Common  Stock
were  outstanding,  of  which  options  to  purchase  474,136  were  immediately
exercisable. Rights to acquire an additional 515,236 shares of Common Stock were
available for  future  grants under  the  Equity Incentive  Plan  (including  an
increase  in the  amount authorized under  the Equity Incentive  Plan of 250,000
shares subject to stockholder  approval). The Company  has filed a  registration
statement  on Form  S-8 to  permit the  shares acquired  upon exercise  of these
options (other  than  those  subject  to  stockholder  approval)  to  be  freely
tradable.
 
    Under  the  Company's 1994  Directors'  Stock Option  Plan  (the "Directors'
Plan"), the Company has issued options to purchase Common Stock at prices  which
are  below current market. Such options are granted pursuant to automatic grants
to non-employee directors. At March 31, 1996, options to purchase 165,000 shares
of Common Stock  were outstanding,  of which  options to  purchase 105,000  were
immediately  exercisable.  Rights to  acquire  an additional  185,000  shares of
Common Stock were available for future grants under the Directors' Plan.
 
    On March 31, 1996, warrants to purchase 106,467 shares of Common Stock  were
outstanding  and exercisable. See  "Description of Capital  Stock -- Options and
Warrants."
 
   
    The Company, subject to certain exceptions, and its officers, directors  and
certain  stockholders holding an aggregate  of approximately 2,668,487 shares of
Common Stock after this offering, have entered into lock-up agreements with  the
Underwriters  pursuant to  which such  stockholders have  agreed not  to sell or
otherwise dispose of any shares  of Common Stock for a  period of 90 days  after
the  date of this Prospectus without the prior written consent of Volpe, Welty &
Company. Upon expiration of the lockup period, these shares will be eligible for
immediate sale, subject in certain cases  to volume and other limitations  under
Rule 144. See "Underwriting."
    
 
    No  prediction can be  made as to the  effect, if any,  that market sales of
shares or the  availability of shares  for sale  will have on  the market  price
prevailing  from time to time. Sales of  substantial numbers of shares of Common
Stock could adversely affect prevailing market prices.

    The Underwriting Agreement provides that the obligations of the Underwriters
are  subject  to  certain conditions  precedent,  including the  absence  of any
material adverse change  in the Company's  business and the  receipt of  certain
certificates  and opinions from the  Company and its counsel.  The nature of the
Underwriters' obligation is such that they are committed to purchase all  shares
of Common Stock offered hereby if any of such shares are purchased.
 
   
    The  Representatives have advised  the Company and  the Selling Stockholders
that the Underwriters propose to offer the shares of Common Stock to the  public
at  the offering  price set forth  on the cover  page of this  Prospectus and to
certain dealers at such  price less a  concession of not in  excess of $.37  per
share,  of which $.10 may  be reallocated to other  dealers. After the offering,
the public offering price, concession and reallowance to dealers may be  reduced
by the Representatives. No such reduction shall change the amount of proceeds to
be  received by  the Company and  the Selling  Stockholders as set  forth on the
cover page of this Prospectus.
    
 
   
    The Company  and a  Selling  Stockholder have  granted the  Underwriters  an
option  for  30 days  after  the date  of this  Prospectus  to purchase,  at the
offering price, less the underwriting discounts and commissions as set forth  on
the  cover page of this Prospectus, up to 415,096 and 4,904 additional shares of
Common Stock, respectively, at the same price  per share as the Company and  the
Selling  Stockholders receive for  the 2,800,000 shares  of Common Stock offered
hereby, solely to cover  over-allotments, if any.  If the Underwriters  exercise
their  over-allotment option, the Underwriters have severally agreed, subject to
certain conditions, to purchase approximately  the same percentage thereof  that
the  number of shares of Common Stock to  be purchased by each of them, as shown
in the foregoing table,  bears to the 2,800,000  shares of Common Stock  offered
hereby.   The  Underwriters  may   exercise  such  option   only  to  cover  the
over-allotments in connection with  the sale of the  2,800,000 shares of  Common
Stock offered hereby.
    
 
    Each  of the  Company's directors and  officers, and  certain other security
holders of the  Company, have agreed  not to  offer, sell, contract  to sell  or
otherwise dispose of Common Stock or securities convertible into or exchangeable
for,  or any rights to purchase or acquire, Common Stock for a period of 90 days
following the Effective Date, without the prior written consent of Volpe,  Welty
&  Company. The Company also has agreed not  to offer, sell, contract to sell or
otherwise dispose of any  shares of Common Stock  or any securities  convertible
into or exchangeable for, or any rights to purchase or acquire, Common Stock for
a  period of  90 days following  the date  of this Prospectus  without the prior
written consent of Volpe, Welty & Company, except for the granting of options or
the sale of stock pursuant to the Company's Option Plan. Volpe, Welty & Company,
in its discretion,  may waive the  foregoing restrictions in  whole or in  part,
with or without a public announcement of such action.
 
                                       45
<PAGE>
    The  offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject  to prior sale and  to withdrawal, cancellation  or
modification  of the offering without notice. The Underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.
 
    In general,  the  rules  of  the Securities  and  Exchange  Commission  (the
"Commission")  will prohibit the Underwriters from making a market in the Common
Stock during the "cooling off" period immediately preceding the commencement  of
sales  in the  offering. The  Commission has,  however, adopted  exemptions from
these rules that permit  passive market making  under certain conditions.  These
rules  permit  an  underwriter to  continue  to  make a  market  subject  to the
conditions, among others, that its  bid not exceed the  highest bid by a  market
maker  not connected  with the offering  and that  its net purchases  on any one
trading day not exceed prescribed limits. Pursuant to these exemptions,  certain
Underwriters,  selling group members (if any) or their respective affiliates may
have engaged in passive market making  in the Company's Common Stock during  the
cooling off period.
 
    The  Company  and  the Selling  Stockholders  have agreed  to  indemnify the
Underwriters against certain liabilities that may be incurred in connection with
this offering, including liabilities under the Securities Act, or to  contribute
payments that the Underwriters may be required to make in respect thereof.
 
                                 LEGAL MATTERS
 
    The  validity of the  shares of Common  Stock offered hereby  will be passed
upon for the  Company by  Cooley Godward Castro  Huddleson &  Tatum, Palo  Alto,
California.  Certain legal matters  will be passed upon  for the Underwriters by
Heller Ehrman White & McAuliffe, San  Francisco, California. Robert L. Jones,  a
partner  at Cooley  Godward Castro  Huddleson & Tatum,  is the  Secretary of the
Company.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
CIMA LABS INC.
 
    We  have  audited  the accompanying  balance  sheets  of CIMA  LABS  INC. (a
development stage company)  as of December  31, 1994 and  1995, and the  related
statements  of operations,  changes in stockholders'  equity and  cash flows for
each of the  three years  in the  period ended December  31, 1995,  and for  the
period  from December 12, 1986 (inception) to December 31, 1995. These financial
statements  are   the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion  on these financial statements based on
our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all material respects, the financial position  of CIMA LABS INC. at December
31, 1994 and 1995, and the results of its operations and its cash flows for each
of the three years in  the period ended December 31,  1995, and the period  from
December 12, 1986 (inception) to December 31, 1995, in conformity with generally
accepted accounting principles.
 
    As  discussed in Note 11 to  the financial statements, the Company's deficit
accumulated during the  development stage and  recurring losses from  operations
raise  substantial doubt about its  ability to continue as  a going concern. The
Company intends to obtain additional capital through a financing transaction  to
permit  it to continue  its operations. The financial  statements do not include
any adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
                 (UNAUDITED WITH RESPECT TO MARCH 31, 1996 AND
             THE THREE-MONTH PERIODS ENDED MARCH 31, 1995 AND 1996)
 
1.  DEVELOPMENT STAGE COMPANY
    CIMA LABS INC. is a development stage company formed on December 12, 1986 to
develop  and  market  certain  effervescent  delivery  technologies  and focused
initially on liquid effervescents. Initial  sales commenced on January 28,  1988
and  have been derived principally from manufacturing of liquid effervescent and
other products for third parties. In September 1992, patent claims were  allowed
on  the  Company's  OraSolv  technology  and  the  Company  began  to  emphasize
development of products using this new technology.
 
    The Company's  strategy is  to enter  into collaborative  arrangements  with
pharmaceutical  and other healthcare companies to develop OraSolv products to be
marketed by  its  corporate partners.  The  Company's future  profitability  is,
therefore,  dependent upon the  Company's ability to  develop products that meet
the requirements of  its corporate partners  and upon the  marketing efforts  of
these corporate partners. Although the Company believes these partners will have
an  economic  motivation to  market these  products  vigorously, the  amount and
timing of resources to be devoted to marketing are not within the control of the
Company. These partners  independently could make  material marketing and  other
commercialization  decisions which  could adversely affect  the Company's future
revenues.  Failure  of   these  partners  to   market  the  Company's   products
successfully  could have  a material adverse  effect on  the Company's financial
condition and result of operations.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CASH EQUIVALENTS
 
    The Company  considers  all highly  liquid  investments with  maturities  of
ninety  days or less when purchased to be cash equivalents. Cash equivalents are
carried at cost which approximates fair market value.
 
SHORT-TERM INVESTMENTS
 
    Company investments are comprised of  debt securities and are classified  as
available for sale. These securities are carried at cost which approximates fair
value.  Realized gains and losses and declines  in value judged to be other than
temporary are included in other income.
 
PATENTS AND TRADEMARKS
 
    Costs incurred  in  obtaining patents  and  trademarks are  amortized  on  a
straight-line  basis  over sixty  months. The  Company periodically  reviews its
patents and trademarks for impairment in value. Any adjustment from the analysis
is charged to operations.
 
PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are  stated at cost. Depreciation is  provided
using  the straight-line  method over the  estimated useful lives  of the assets
ranging from  3 to  15  years. Leasehold  improvements  are amortized  over  the
shorter of the term of the lease or life of the asset.
 
INVENTORIES
 
    Inventories  are valued at cost under  the first-in, first-out (FIFO) method
which is not in excess of market.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    In March  1995,  the  Financial Accounting  Standards  Board  (FASB)  issued
Statement  No. 121, "ACCOUNTING FOR THE  IMPAIRMENT OF LONG-LIVED ASSETS AND FOR
LONG-LIVED ASSETS TO  BE DISPOSED OF",  which requires impairment  losses to  be
recorded  on long-lived assets used in  operations when indicators of impairment
are present and the undiscounted cash  flows estimated to be generated by  those
assets are less than the assets'

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                 (UNAUDITED WITH RESPECT TO MARCH 31, 1996 AND
             THE THREE-MONTH PERIODS ENDED MARCH 31, 1995 AND 1996)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
carrying  amount. Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company will adopt Statement No.
121 in the  first quarter of  fiscal 1996 and,  based on current  circumstances,
does not believe the effect of adoption will be material.
 
USE OF ESTIMATES
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect  the amounts reported  in the  financial statements and
accompanying notes. Actual results could differ from those estimates.
 
INCOME TAXES
 
    Taxes are  provided  based  on earnings  reported  for  financial  statement
purposes.  Deferred income taxes are  provided for temporary differences between
financial reporting and tax bases of assets and liabilities under the  liability
method.
 
REVENUE RECOGNITION
 
    Sales  of product are recorded upon  shipment. Research and development fees
are recognized as the  services are provided.  Revenues from license  agreements
are  recorded  when  obligations  under the  agreement  have  been substantially
completed. Royalties are recorded when earned.
 
NET LOSS PER COMMON SHARE
 
    The primary net loss per share is computed using the weighted average number
of shares of common stock and common stock equivalents, if dilutive, outstanding
during the periods  presented. The  fully diluted  loss per  share is  presented
using the "if converted" method and reflects the impact of the conversion of the
preferred  stock  to  common  stock  at the  beginning  of  the  earliest period
presented or at the date of issuance,  if later. For periods prior to July  1994
(the  initial public offering),  the loss per  share amounts give  effect to the
application of  Securities  and  Exchange Commission  ("SEC")  Staff  Accounting
Bulletin  ("SAB") No.  83. Pursuant to  SAB No.  83, common stock  issued by the
Company at prices less than the initial public offering price during the  twelve
months  immediately preceding the initial public offering, plus the common stock
equivalent shares  granted  at exercise  prices  less than  the  initial  public
offering  price during the same period, have been included in the calculation of
shares used in the calculation of net loss per share as if they were outstanding
for all periods prior to the initial public offering.
 
RECLASSIFICATIONS
 
    Certain reclassifications  have been  made to  the 1994  and 1995  financial
statements to conform to the 1996 classifications.
 
INTERIM FINANCIAL INFORMATION
 
    The  accompanying  financial statements  as of  March 31,  1996 and  for the
three-month periods ended March 31, 1995 and 1996 are unaudited. In the  opinion
of  the  management  of  the Company,  these  financial  statements  reflect all
adjustments, consisting only of normal and recurring adjustments, necessary  for
a  fair presentation of the financial  statements. The results of operations for
the three-month period ended  March 31, 1996 are  not necessarily indicative  of
the results that may be expected for the full year ending December 31, 1996.
 
3.  SHORT-TERM INVESTMENTS
    At   December  31,   1994,  short-term   investments,  including  $1,491,293
classified as  cash  equivalents,  consisted of  U.S.  Treasury  securities  and
obligations of U.S. Government agencies.

    The  Company has a Directors' Stock  Option Plan (the "Plan") which provides
for the granting to non-management directors of the Company options to  purchase
shares  of Common  Stock. The  maximum number  of shares  with respect  to which
options may be granted  under this Plan  is 350,000 shares.  As of December  31,
1995,  options to purchase 165,000  shares of Common Stock  have been granted at
prices ranging from $4.75  to $9.00 per  share. To date,  none of these  options
have been exercised.
 
    In  connection with a bridge financing  in 1989, the Company issued warrants
to purchase 7,365  shares of  its Common  Stock at  $5.60 per  share. Of  these,
warrants  to purchase 7,142  shares were exercised in  April 1994. The remaining
warrants expired in the same month.
 
    In connection with  $950,000 of  bridge financing  in 1991  and $467,500  of
bridge  financing in 1992, the Company  issued warrants to purchase an aggregate
of 189,801 shares  of its  Common Stock  at $6.00  per share.  The warrants  are
exercisable at various dates from January 1996 to January 1997.
 
    In  connection with an  equipment lease agreement  entered into during 1991,
the Company issued  warrants to  purchase 37,917  shares of  Series D  Preferred
Stock  at $6.00 per share. The warrants were exercised in a cashless transaction
in January 1995.
 
    In October 1995, the Financial  Accounting Standards Board issued  Statement
of   Financial  Accounting  Standards  No.   123,  "ACCOUNTING  FOR  STOCK-BASED
COMPENSATION." The Company has not determined the impact of the new statement on
its financial statements. The Company  currently accounts for its options  under
the  provisions of  Accounting Standards Board  Opinion No.  25, "Accounting for
Stock Issued to Employees."

9.  DEFINED CONTRIBUTION PLAN
    The Company established a 401(k)  plan (the "Plan") effective January  1993.
All  personnel employed on January  1, 1993 were eligible  to participate in the
Plan. Others  become  eligible to  participate  at age  21  with six  months  of
service.
 
    Contributions  to  the Plan  are made  through  employee wage  deferrals and
employer matching contributions. The  employer matching contribution  percentage
is  discretionary  and  determined  each  year.  In  addition,  the  Company may
contribute two discretionary amounts; one to non-highly compensated  individuals
and  another  to all  employees. To  qualify for  the discretionary  amounts, an
employee must be employed  by the Company on  the last day of  the Plan year  or
have been credited with a minimum of 500 hours of service during the Plan year.
 
    The  401(k) expense for the years ended December 31, 1993, 1994 and 1995 was
$14,078, $16,289 and $28,335, respectively.
 
10. STOCK SPLIT
    The Company's Board of Directors and stockholders approved a 1-for-2 reverse
stock split that was effective upon  the closing of the initial public  offering
in  July 1994.  All share and  per share  information has been  adjusted to give
effect to the stock split in the financial statements.
 
11. GOING CONCERN
    Net losses since  the Company's  inception have resulted  in an  accumulated
deficit  balance of $29,259,472  at December 31, 1995.  The Company's ability to
continue as  a going  concern and  the  realization of  its assets  and  orderly
satisfaction of its liabilities are dependent on obtaining additional funds from
outside  sources and generating sufficient  working capital from operations. The
Company is currently exploring financing alternatives and anticipates completing
a financing  transaction  in 1996.  The  Company believes  that  the  successful
completion of a financing transaction will satisfy its cash requirements for the
next  twelve months. However, there can be no assurance that the Company will be
successful in completing a financing transaction.
