Item 1. Description of Business

      Except for historical  information contained in this document, the matters
discussed in this report contain forward  looking  statements that involve risks
and  uncertainties.  These  future  risks and  uncertainties  could cause actual
results to differ materially.

General

      Cyanotech Corporation is a leader in the development and commercialization
of high value products derived from  microalgae.  Microalgae are a diverse group
of over  30,000  species  of  microscopic  plants  which  have a wide  range  of
physiological and biochemical  characteristics and naturally contain high levels
of proteins,  amino acids,  vitamins,  pigments and enzymes. Since 1983, we have
designed,  developed  and  implemented  proprietary  production  and  harvesting
technologies,  systems and processes  which  eliminate many of the stability and
contamination  problems frequently  encountered in the production of microalgae.
We  believe  that our  technology,  systems,  processes  and  favorable  growing
location  permit  year-round  harvesting  of our  microalgal  products in a cost
effective manner.

      We currently  produce natural products from microalgae for the nutritional
supplement, aquaculture feed, and immunological diagnostics markets. Since 1985,
Cyanotech  has been  producing  microalgae-based  "Spirulina"  products  for the
vitamin and supplement  market.  Spirulina Pacifica(TM), which is our  principal
source  of  revenue,  is a unique  strain  of  Spirulina  developed  by us which
provides a vegetable-based,  highly absorbable source of natural  beta-carotene,
mixed carotenoids,  B vitamins, gamma linolenic acid ("GLA"), protein, essential
amino acids and other phytonutrients. We currently market our Spirulina products
in the United States and  thirty-seven  other countries  though a combination of
retail,  wholesale,  and private  label  channels.  In early 1997, we introduced
NatuRose(TM) to the worldwide aquaculture industry.   NatuRose is our brand name
for  natural  astaxanthin  (pronounced "as-ta-zan-thin").   Astaxanthin is a red
pigment from the microalgae, Haematococcus, and is used in aquaculture to impart
a pink  to  red  color  to pen-raised  fish and shrimp.  NatuRose  competes with
synthetic  astaxanthin  whose  worldwide  annual  sales  are  estimated  at more
than $150 million.

      Cyanotech has recently  increased its commitment to developing  microalgae
for the expression of native as well as heterologous  proteins through molecular
biology.  Because microalgae  naturally contain high levels of protein,  because
they have a uniform  cell  structure,  and because they can grow up to 100 times
faster than land plants,  they offer unique advantages over plant,  bacterial or
mammalian  systems for the  expression of proteins.  Like higher  plants,  algal
expression  systems can be produced on a large-scale  with culture volumes of up
to 600,000 liters without problems of  contamination by bacterial  endotoxins or
animal  viruses.  Unlike  higher  plants,  however,  the time  required  to grow
transgenic  algae  expressing the desired  protein is on the order of one to two
months  rather  than the one to two  years  that  would be  required  in corn or
soybeans,  for example.  Since 1996, Cyanotech has been developing a genetically
engineered biopesticide for the control of mosquitoes. A natural toxin gene from
Bacillus  thuringiensis  var.  israelensis  (Bti)  is being  transformed  into a
blue-green algae,  Synechococcus,  a food for mosquito larvae. When applied to a
mosquito-infested  body of  water,  the  algae  could  act as an  effective  and
environmentally  safe means of control.  In April 1998, we announced the signing
of a licensing  agreement and collaboration  with The Scripps Research Institute
in La Jolla,  California to produce a new compound for use in chiral  chemistry.
Under the terms of this  agreement,  Cyanotech will be responsible for the large
scale production and purification of a catalytic antibody which was generated in
the Scripps  laboratory  and  subsequently  expressed as a transgene in algae by
Scripps  scientists.  Cyanotech  intends  to  continue  to exploit  the  largely
untapped  commercial  opportunities of microalgae by producing  natural products
and also genetically engineered products through molecular biology.

Industry Background

      Microalgae  are a diverse  group of  microscopic  plants  that have a wide
range of physiological and biochemical  characteristics  and naturally  contain,
among other things, high levels of proteins, amino acids, vitamins, pigments and
enzymes.   Microalgae  have  the  following   properties  that  make  commercial
production  attractive:  (1) microalgae grow much faster than land grown plants,
often up to 100 times faster;  (2) microalgae have a uniform cell structure with
no bark, stems,  branches or leaves, which permits easier extraction of products
and higher  utilization of the microalgae cells; (3) the cellular  uniformity of
microalgae  makes it practical to manipulate and control  growing  conditions in
order to optimize a particular  cell  characteristic;  (4) microalgae  contain a
wide array of vitamins and other  important  nutrients;  (5) microalgae  contain
natural pigments; and (6) are a potential source of medical products.

      Current  commercial  applications  for these  microscopic  plants  include
nutritional  products,  diagnostic  products,  aquaculture  feed  and  pigments,
natural food colorings and research grade  chemicals.  The Company believes that
microalgae  could  potentially  be  used  for  other  commercial   applications,
including   genetically   engineered   products   for   the   biopesticide   and
pharmaceutical  industries.  The most significant  microalgae  products produced
today are algae utilized as food supplements.

      While many  unique  compounds  have been  identified  in  microalgae,  the
efficient  and cost  effective  commercial  production of microalgae is elusive.
Many  microalgae  culture  systems over the last 20 years have  failed.  Because
microalgae produced for food supplements are typically  cultivated and harvested
outdoors,  production is significantly  affected by climate,  weather conditions
and the chemical  composition of the culture media. Without consistent sunlight,
warm temperature,  low rainfall and proper chemical balance, microalgae will not
grow quickly,  resulting in longer harvesting cycles, decreased pond utilization
and increased cost. Furthermore, microalgal growth requires a very nutrient rich
environment.  The high  nutrient  levels  in the  ponds  promote  the  growth of
unwanted organisms, or "weeds," if the chemical composition of the ponds changes
from its required balance.  Once  contamination  occurs, a pond must be emptied,
cleaned and refilled,  a process that further  decreases  pond  utilization  and
increases production costs.


Cyanotech's Technology

         Since 1983, we have  designed,  developed and  implemented  proprietary
production and harvesting technologies,  systems and processes which reduce many
of the  stability  and  contamination  problems  frequently  encountered  in the
production  of  microalgae.  This  proprietary  production  system  is  known as
Integrated  Culture Biology  Management (or "ICBM").  Through the application of
this  technology,  our  Spirulina  culture  ponds can be  productive  year-round
without any significant loss in productivity  due to  contamination  and many of
our production  ponds, all based in Hawaii,  have been in continuous  production
since 1988. We believe that such an accomplishment remains unique to Cyanotech.

                                       3
<PAGE>
         In addition to the advantages of our ICBM technology, we have developed
a patented  system for the  recovery of carbon  dioxide  from our drying  system
exhaust  gas,  called  Ocean-Chill  Drying.  Since  microalgae  are  essentially
microscopic "plants", they require sunlight, water, carbon dioxide and nutrients
for optimal  growth.  By  recovering  carbon  dioxide  that would  otherwise  be
released into the atmosphere, we can divert the recovered carbon dioxide back to
the algae  cultures.  This  process  provides us with another  significant  cost
advantage  over other  microalgae  producers who must purchase  carbon  dioxide.
Moreover,   Ocean-Chill  Drying  dries  microalgal  products  in  a  low  oxygen
environment,  which protects oxygen sensitive  nutrients.  In addition,  we have
developed an  automated  Spirulina  processing  system,  which  enables a single
operator to harvest and dry the Spirulina powder.

         Another  major  advantage  for us is  the  location  of our  production
facility at the Hawaii Ocean  Science and  Technology  ("HOST")  Park at Keahole
Point,  Hawaii.  We believe that the combination of consistent warm temperature,
abundant  sunlight,  and low  rainfall  at this  facility  makes  this a  highly
favorable location for the economical, large-scale cultivation of microalgae. In
contrast to our  facility,  microalgae  producers in other areas  lacking  these
favorable characteristics stop producing for up to four months a year because of
less favorable climate or weather  conditions.  At the HOST Park, we have access
to cold,  clean,  deep sea water that is pumped from a depth of 2,000 feet. This
sea water is used both as a source of nutrients for microalgae  culture and as a
cooling agent in the Ocean-Chill Drying process.  Additionally, our facility has
access to a complete  industrial  infrastructure  and is located 30 miles from a
deep water port and adjacent to an international airport.

         Applying our experience in cultivating  and  harvesting  Spirulina,  we
began commercial production of our natural astaxanthin product, NatuRose, during
the fourth quarter of fiscal 1997. The product is produced using our large-scale
photo-bioreactor  system,  referred to as the PhytoMax Pure Culture  System,  or
PhytoMax PCS, which  incorporates  closed-culture  technology and allows for the
large-scale  commercial  cultivation  of  microalgae  strains that are otherwise
highly susceptible to environmental contamination. With the PhytoMax PCS, we now
have the potential to produce a broader  range of new products from  microalgae.
Such    products    could    include    genetically-engineered    biopesticides,
nutraceuticals,     additional     nutritional    products,     pharmaceuticals,
poly-unsaturated  fatty acids,  anti-microbial  agents, plant growth regulators,
and anti-viral compounds.

         Our primary  objective is to be the leading  developer  and producer of
microalgal  products in our  existing  and future  markets.  We believe that the
combination of our ICBM technology, our PhytoMax PCS technology, our Ocean-Chill
Drying process, our automated processing system and a favorable growing location
with year-round  production  capabilities,  can be  successfully  applied to the
commercial cultivation of many species of microalgae.


Products

  Spirulina

         Our principal product,  accounting for 95% and 98% of net sales for the
years ended March 31, 1998 and 1997,  respectively,  is a nutritional microalgae
marketed as Spirulina Pacifica. Developed by us and sold worldwide to the health
and natural  foods market,  Spirulina  Pacifica is a unique strain of microalgae
that is a highly absorbable source of natural beta carotene,  mixed carotenoids,
B vitamins,  GLA, protein,  essential amino acids and other  phytonutrients.  We
believe we were the first Spirulina  producer to have its products and processes
certified  organic and we are the only  microalgae  producer to have its quality
system registered under the ISO 9002-94 standards.

         Cyanotech produces Spirulina Pacifica in three forms: powder, flake and
tablets.  Powder is used as an ingredient in nutritional  supplements and health
food drinks while flakes are used as a seasoning on various  foods.  Tablets are
consumed daily as a dietary supplement.  We also produce and market two products
under the Hawaiian  Energizer  name.  Hawaiian  Energizer  sports drink contains
complex  carbohydrates  and  vegetarian  protein in  combination  with Spirulina
Pacifica,  Bee Pollen and Siberian Ginseng.  Hawaiian  Energizer tablets contain
Spirulina Pacifica, Bee Pollen and Siberian Ginseng.

                                       4
<PAGE>


         We  anticipate  that  sales of our  Spirulina  Pacifica  products  will
continue to  constitute a  substantial  portion of net sales during fiscal 1999.
Any decrease in the overall  level of sales of, or the prices for, our Spirulina
Pacifica  products,  whether  as a result of  competition,  change  in  consumer
demand, increased worldwide supply of Spirulina or any other factors, would have
a material  adverse effect on our business,  financial  condition and results of
operations.

  Natural Astaxanthin

         The  fiscal  year  ended  March  31,  1998 was the  first  full year of
commercial production for our natural astaxanthin product, NatuRose. Astaxanthin
is a red pigment used primarily in the aquaculture industry to impart pink color
to the flesh of pen-raised fish and shrimp.  The astaxanthin market currently is
dominated  by  a  single  producer,  Hoffmann-LaRoche,  who  produces  synthetic
astaxanthin  from  petrochemicals.  Hoffmann-LaRoche  currently  sells synthetic
astaxanthin  to the  aquaculture  industry  at  approximately  $2,500  per  pure
kilogram. As a result of continued growth in the world aquaculture industry, the
world market for  astaxanthin is estimated to currently  exceed $150 million per
year.  Although  sales of NatuRose for the fiscal year ended March 31, 1998 were
nominal,  we anticipate that such sales will constitute a significant portion of
total sales in future periods.

  Phycobiliproteins

         Cyanotech also produces phycobiliproteins which are sold to the medical
and biotechnology  research industry.  Phycobiliproteins  are highly fluorescent
pigments purified from microalgae. Their spectral properties make them useful as
tags or markers  in many kinds of  biological  assays,  such as flow  cytometry,
fluorescence  immunoassays and fluorescence microscopy. We anticipate that sales
of phycobiliproteins  will not represent a significant  component of total sales
in future periods.


Products Under Development

         A new  product  which we are  continuing  to develop  is a  genetically
engineered   mosquitocide   from  microalgae.   The  toxin  gene  from  Bacillus
thuringiensis  var.  israelensis (Bti) is being cloned into the blue-green algae
Synechococcus.  The bacterial toxin Bti is very specific to mosquitoes and black
flies,  while the  blue-green  algae is a food for  mosquito larvae.  We believe
that, when applied to a mosquito-infested body of water, this algae could act as
an effective and environmentally safe means of control.

         In April  1998,  we  signed an  exclusive  agreement  with The  Scripps
Research  Institute  to produce  the  Institute's  patented  Aldolase  Catalytic
Antibody 38C2 in  microalgae.  The  genetically  engineered  aldolase  catalytic
antibody may have  numerous  potential  applications  in  industrial  synthesis,
including the synthesis of certain anti-cancer compounds. Under the terms of the
exclusive license  agreement,  Scripps will provide the genetically  engineered,
live  microalgae   containing  the  catalytic  aldolase  protein  to  Cyanotech.
Production of reagent quantities is expected to be available within eight months
if development tests prove its feasibility.

         Development  of these  products is continuing and there is no assurance
that commercial products will be achieved. Our inability to successfully develop
or commercialize additional products could have a material adverse effect on our
business, financial condition and results of operations.


Research & Development

         Cyanotech's  expertise is in the  development of efficient,  stable and
cost-effective  production  systems for  microalgal  products.  Our  researchers
investigate  specific  microalgae   identified  in  scientific   literature  for
potentially  marketable  products and then develop the  technology  to grow such
microalgae on a commercial scale.

                                        5
<PAGE>

         During  fiscal  1998,  the Company  incurred  $677,000 in research  and
development expenses,  compared with $587,000 and $351,000 in the years 1997 and
1996, respectively.  The Company intends to continue to develop new products and
prioritizes its research and development activities to focus on projects that it
believes will have the greatest market acceptance and achieve the highest return
on the Company's investment. Successful microalgal product development is highly
uncertain  and is  dependent on numerous  factors,  many of which are beyond the
Company's control. Products that appear promising in early phases of development
may be found to be  ineffective,  may be uneconomical  because of  manufacturing
costs or other  factors,  may be  precluded  from  commercialization  due to the
proprietary  rights  of  other  companies,  or may  fail  to  receive  necessary
regulatory approvals.


Distribution

         The majority of our bulk  Spirulina  sales are to companies  with their
own  Spirulina  product  lines.  Many of these  companies  identify  and promote
Cyanotech's Hawaiian Spirulina in their products.  In the United States, we sell
directly to health food  manufacturers  and health  food  formulators.  Packaged
consumer products sell in the domestic market through an established health food
distribution  network.  Orders for packaged  consumer  products are taken at the
store level by one of 23 regional broker representatives and shipped through one
of 36 distributors.  In selected foreign  markets,  we have appointed  exclusive
sales distributors for both bulk Spirulina and packaged consumer products.

         In the years ended March 31, 1998, 1997 and 1996,  international  sales
accounted for approximately 44%, 62% and 55%, respectively, of our net sales. We
expect that international sales will continue to represent a significant portion
of our net sales.  Our business,  financial  condition and results of operations
may be  materially  adversely  affected  by  any  difficulties  associated  with
managing accounts receivable from international  customers,  tariff regulations,
imposition of governmental controls, political and economic instability or other
trade restrictions.  Although our international sales are currently  denominated
in United States dollars,  fluctuations  in currency  exchange rates could cause
our products to become  relatively  more  expensive to customers in the affected
country, leading to a reduction in sales in that country.


Customers

Spirulina

         No single customer  accounted for more than 10% of net sales during the
year ended March 31, 1998. Our largest  customer during 1997 and 1996 was a Hong
Kong-based network marketing company which purchases both bulk Spirulina and our
packaged consumer  products for distribution,  primarily in mainland China. From
March through  September  1997,  this customer was  restricted  from hosting any
large scale  distributor  meetings due to a delay in  receiving  recertification
from the  Chinese  government.  As a  result,  orders  from this  customer  were
significantly  reduced from previous periods. For the year ended March 31, 1998,
this customer  accounted for less than 5% of  Cyanotech's  net sales,  down from
approximately  34% and 29% of sales in the years  ended March 31, 1997 and 1996,
respectively.  Subsequent  to the end of fiscal  1998,  the  Chinese  government
imposed a ban on all network market organizations, effective October 1, 1998.
Sales to this customer are expected to be minimal.

                                       6
<PAGE>
         We  market  and sell  our  Spirulina  products  to a  variety  of other
customers, including:

          Health  Food  Manufacturers.   Health  food  manufacturers  often  use
Cyanotech's  Spirulina  products as a key  ingredient  in their  Spirulina-based
products, or as an ingredient in their health food formulations. These customers
purchase bulk powder or bulk tablets and package the products  under their brand
label for sale to the health and  natural  food  markets.  Many of the  products
produced by these  customers are often marketed and sold  domestically in direct
competition  with our  Nutrex  line of retail  consumer  products.  However,  we
differentiate  our Nutrex products from those of our bulk customers by reserving
the certified organic line of products for sale in the United States exclusively
under our Nutrex label.

         Private  Label  Customers.  We currently  provide  private label retail
consumer products to two international  customers.  Products for these customers
are  manufactured  only  upon  receipt  of an  order  and  no  finished  product
inventories are maintained.

         Retail Distributors.  Retail distributors act as product wholesalers to
independent  and chain  retailers.  The majority of domestic Nutrex sales in the
year ended March 31, 1998 were to 36 distributors.

         Natural  Products  Distributors.  In the year ended March 31, 1998,  we
sold bulk Spirulina products to ten domestic and seven foreign customers engaged
in the business of distributing natural raw materials to health and natural food
manufacturers.  These  distributors  provide their  customers with  standardized
quality control,  warehousing and distribution services, and charge a mark-up on
the products for providing these services.  These distributors may differentiate
the products they sell,  but they generally  treat the products as  commodities,
with price being the major determining factor in their purchasing decision.

Natural Astaxanthin

         Our  NatuRose  product  is being  sold  through a network of agents and
distributors  directly to aquaculture  farmers,  vitamin suppliers,  aquaculture
feed  manufacturers  and other end users in 15 countries for use in  aquaculture
feed, poultry feed and pet feed industries.  In March 1998, the Company signed a
letter of intent with a major European life sciences  company  operating in over
150  countries  for sales  and  distribution  of  NatuRose  and other  Cyanotech
products in certain European countries.  This distributor  posesses  significant
expertise  and worldwide  marketing  experience  in animal  nutrition  products.
Initially,  the  distributor  will test NatuRose and Spirulina for use in animal
feeds for up to six months and, if the testing is successful, we would negotiate
a definitive sales and distribution agreement.

Competition

 Spirulina

         Our  Spirulina  Pacifica  products  compete with a variety of vitamins,
dietary  supplements,  other algal  products  and similar  nutritional  products
available to consumers.  The nutritional  products market is highly competitive.
It  includes   international,   national,   regional  and  local  producers  and
distributors,  many of whom have greater  resources than Cyanotech,  and many of
whom  offer a  greater  variety  of  products.  Our  direct  competition  in the
Spirulina market currently is from Dainippon Ink and Chemical Company's facility
in California and several farms in China.  To a lesser  extent,  we compete with
numerous  smaller  farms in China,  India,  Thailand,  Brazil and South  Africa.
Packaged  consumer  products  marketed  under our Nutrex brand also compete with
products  marketed by health  food  manufacturing  customers  of  Cyanotech  who
purchase bulk  Spirulina  from us and package it for retail sales. A decision by
another  company  to  focus on  Cyanotech's  existing  or  target  markets  or a
substantial  increase in the overall  supply of Spirulina  could have a material
adverse effect on our business,  financial  condition and results of operations.
There can be no  assurance  that we will not  experience  competitive  pressure,
particularly with respect to pricing,  that could adversely affect our business,
financial condition and results of operations.

Natural Astaxanthin

         Our natural astaxanthin product,  NatuRose,  competes directly with the
synthetic    astaxanthin    product   produced   and   marketed   worldwide   by
Hoffmann-LaRoche.  In addition,  several other companies have announced plans to
produce commercial quantities of natural astaxanthin from microalgae and Phaffia
yeast. We believe that these  companies are only producing small  quantities for
test purposes.  Although we are unaware of any studies  indicating  that natural
astaxanthin has any benefits not otherwise provided by synthetic astaxanthin, we
believe there is commercial  demand for a natural  astaxanthin  product and that
our NatuRose product can compete on the basis of product performance and price.

Phycobiliproteins

         Four major competitors manufacture  phycobiliprotein products for sale,
including Molecular Probes, Inc., Quantify Inc., Martek Biosciences  Corporation
and Prozyme Inc.  Cyanotech  competes with these companies on the basis of price
and quality. New synthetic  fluorescent compounds have been developed by a third
party  which  are  superior  to  phycobiliproteins  in  some  applications.  The
advantage of the  synthetic  compounds is their lower  molecular  weight and, in
some cases,  their lower cost.  While our  phycobiliprotein  products may not be
able to compete  effectively  against synthetic  compounds in some applications,
Cyanotech's  phycobiliproteins  have gained a  reputation  for high quality at a
competitive price.


Government Regulation

         Cyanotech's  products,  potential  products and its  manufacturing  and
research  activities are subject to varying degrees of regulation by a number of
government  authorities in the United States and in other  countries,  including
the Food and Drug  Administration (the "FDA") pursuant to the Federal Food, Drug
and Cosmetic Act and by the  Environmental  Protection  Agency ("EPA") under the
Federal  Insecticide,   Fungicide,   and  Rodenticide  Act  ("FIFRA").  The  FDA
regulates, to varying degrees and in different ways, dietary supplements,  other
food products, diagnostic medical devices and pharmaceutical products, including
their  manufacture,   testing,  exportation,   labeling,  and,  in  some  cases,
advertising.  Generally,  prescription  pharmaceuticals  and  certain  types  of
diagnostic products, such as medical devices, are regulated more rigorously than
dietary supplements.  The EPA also rigorously regulates pesticides,  among other
types of products.

         Cyanotech is also  subject to other  federal,  state and foreign  laws,
regulations  and policies with respect to labeling of its products,  importation
of organisms,  and occupational safety, among others. Federal, state and foreign
laws,  regulations  and policies are always subject to change and depend heavily
on   administrative   policies  and   interpretations.   We  work  with  foreign
distributors  to ensure  our  compliance  with  foreign  laws,  regulations  and
policies.  There can be no  assurance  that any changes with respect to federal,
state and foreign laws, regulations and policies, and, particularly with respect
to the FDA and EPA or other such regulatory  bodies,  with possible  retroactive
effect,  will not have a  material  adverse  effect on our  business,  financial
condition and results of  operations.  There can be no assurance that any of our
potential products will satisfy applicable regulatory requirements.

         The Federal  Dietary  Supplement  Health and  Education  Act  ("DSHEA")
regulates  the use and  marketing  of  dietary  supplements,  including  vitamin
products.  The DSHEA  covers only dietary  supplements  and contains a number of
provisions that  differentiate  dietary  supplements from other foods. The DSHEA
also sets forth standards for adulteration of dietary supplements or ingredients
thereof and  establishes  current  food Good  Manufacturing  Practices  ("cGMP")
requirements for dietary supplements. It also provides detailed requirements for
the  labeling  of  dietary  supplements,   including  nutrition  and  ingredient
labeling.  We currently believe that Spirulina  Pacifica,  marketed as a dietary
supplement, is exempt from FDA regulation as a food additive.

                                       8
<PAGE>
         Our Spirulina  manufacturing  processes  and our contract  bottlers are
required  to adhere to cGMP as  prescribed  by the FDA.  We believe  that we are
currently in compliance  with all  applicable  cGMP and other food  regulations.
Compliance  with relevant cGMP  requirements  can be onerous and time consuming,
and there can be no assurance  that  Cyanotech can continue to meet relevant FDA
manufacturing  requirements for existing  products or meet such requirements for
any future  products.  Ongoing  compliance  with food cGMP and other  applicable
regulatory  requirements are monitored through periodic inspections by state and
federal  agencies,  including  the FDA,  the  Hawaii  Department  of Health  and
comparable  agencies  in  other  countries.  Our  processing  facility  is  also
inspected annually for organic certification by Quality Assurance  International
and for Kosher  certification  by the Kosher Overseers  Association.  The use of
Spirulina as a food  additive for seasoning on salads or pasta or for such other
food  uses has not been  cleared  by the FDA,  however,  the FDA has  recognized
Spirulina as a safe food. We currently market the product for these food uses on
the basis of our belief  that its use in these food  applications  is  generally
recognized as safe and therefore is not subject to FDA pre-market  clearances as
a food additive.

         Our natural astaxanthin product,  NatuRose,  has received clearance for
use as a feed and food color  additive in Japan but will need  clearance for use
as a feed color  additive  in the  United  States and  Canada.  We are  actively
pursuing  clearance for use in the U.S. markets and in February 1998,  submitted
our petition for FDA  approval.  We are  presently  assembling  our petition for
approval  for the  Canadian  Food  Industry  Agency,  and expect to submit  this
petition by the end of calendar 1998. The process of obtaining  clearances for a
new color  additive is expensive and time  consuming.  Extensive  information is
required on the toxicity of the additive,  including carcinogenicity studies and
other  animal  testing.  No  assurances  can be given  that any of our  proposed
products  intended  for use as a feed  additive  will be approved for use in the
United States or Canada on a timely basis, if at all.

         As in vitro  diagnostic  medical  device  components,  phycobiliprotein
products do not currently require pre-market  clearances by the FDA. However, as
a component of a medical  device,  they can be subject to other various  medical
device requirements, including cGMP requirements.

         Work is continuing on our genetically-engineered  mosquitocide project.
We are aware  that any  resulting  product  will be  subject  to  validation  of
efficacy  though field trials.  If proven  effective,  any potential  commercial
product will be subject to regulatory  approval by the EPA for use in the United
States.  However, Bti is currently approved for use as a biopesticide by the EPA
and the World Health Organization.  We are uncertain of regulatory  requirements
in other potential markets at this point.


Patents, Licenses and Trademarks

         Although  we  regard  our   proprietary   technology,   trade  secrets,
trademarks and similar intellectual property as critical to our success, we rely
on a combination of trade secret, contract,  patent, copyright and trademark law
to establish and protect our rights in our products and technology. There can be
no assurance that we will be able to protect our  technology  adequately or that
competitors  will not be able to develop similar  technology  independently.  In
addition,  the laws of certain  foreign  countries may not protect the Company's
intellectual  property  rights  to the same  extent  as the  laws of the  United
States.  Cyanotech has had two United States patents issued to it. Litigation in
the United  States or abroad  may be  necessary  to enforce  our patent or other
intellectual  property  rights,  to protect our trade secrets,  to determine the
validity  and scope of the  proprietary  rights  of others or to defend  against
claims of  infringement.  Such litigation,  even if successful,  could result in
substantial  costs and diversion of resources and could have a material  adverse
effect  on  our  business,   results  of  operations  and  financial  condition.
Additionally,  although  currently  there are no pending claims or lawsuits that
have been brought against us, if any such claims are asserted against us, we may
seek to obtain a license under the third party's  intellectual  property rights.
There can be no assurance,  however,  that a license would be available on terms
acceptable or favorable to us, if at all.

Associates

         Cyanotech  employed 65 associates as of March 31, 1998, of which 64 are
full-time.  Approximately  31  associates  are  involved in the  harvesting  and
production process, 16 are involved in research and product development, and the
remainder are involved in sales, administration and support. Management believes
that its  relations  with  its  associates  are  good.  We have not  experienced
difficulty in attracting personnel and none of our associates are represented by
a labor union.


Industry Segments and Export Sales

         The Company has no assets oustide of the United  States.  The Company's
business  consists of one industry  segment and is grouped into five  geographic
areas:  United States,  Canada/South  America,  Europe,  China and Asia/Pacific,
excluding  China. The following table summarizes the product sales revenues from
unaffiliated customers in each of the five geographic regions:

         The  Company  believes  that its profit  margin on export  sales is not
significantly  different from that realized on sales in the United  States.  All
foreign product sales transactions are consummated in U.S. dollars.


Item 2. Description of Properties

         Cyanotech  Corporation is located in Kailua-Kona,  Hawaii,  at the HOST
Park and also owns a 2,500 square foot sales office in a light  industrial  area
located  approximately  four miles from the HOST  Park.  The HOST Park  facility
consists of  approximately  183 leased acres.  Approximately  90 acres have been
fully  developed  and  contain  production  ponds,  a  processing   facility,  a
laboratory,  and  administrative  offices.  All  products  are  produced at this
facility.  The  property  is leased  from the  State of  Hawaii  under a 30-year
commercial  lease  expiring  in 2025.  During  1997,  we  reached a  preliminary
agreement  with the State of Hawaii to lease an additional 93 acres for 30 years
at the HOST Park, which increased the total acreage under lease to 183 acres. We
plan to use this new property to construct a larger NatuRose production facility
and  additional  culture  ponds that would use the PhytoMax PCS  technology.  We
believe  that there is  sufficient  available  land at the HOST Park to meet our
currently planned future needs. Our Nutrex,  Inc.  subsidiary  maintains a sales
office in Kailua-Kona, Hawaii.


Item 3. Legal Proceedings

         Cyanotech  is not  currently  subject  to any  material  pending  legal
proceedings.

         We maintain product liability insurance in limited amounts for products
involving  human  consumption.  In the opinion of  management,  broader  product
liability insurance coverage is prohibitively expensive at this time.

                    INDEPENDENT AUDITORS' REPORT ON SCHEDULE




The Board of Directors
Cyanotech Corporation:

Under date of April 27, 1998, we reported on the consolidated  balance sheets of
Cyanotech  Corporation  and  subsidiaries as of March 31, 1998 and 1997, and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the years in the  three-year  period ended March 31, 1998,  as
contained  in  the  1998  annual  report  to  stockholders.  These  consolidated
financial statements and our report thereon are incorporated by reference in the
annual report on Form 10-K for the year ended March 31, 1998. In connection with
our audits of the  aforementioned  consolidated  financial  statements,  we also
audited the related financial  statement  schedule as listed in the accompanying
index. The financial  statement  schedule is the responsibility of the Company's
management.  Our  responsibility  is to  express  an  opinion  on the  financial
statement schedule based on our audits.

In our opinion,  such financial statement schedule,  when considered in relation
to the  basic  consolidated  financial  statements  taken as a  whole,  presents
fairly, in all material respects, the information set forth therein.

proprietary  property of Scripps  developed  in the  laboratory  of Dr.  Stephen
Mayfield for producing Aldolase Catalytic  Antibody 38C2,  including  materials,
processes,  information and know-how related thereto, whether or not the same is
eligible for protection under the patent laws of the United States or elsewhere,
and whether or not any such materials,  processes and technology, or information
related thereto,  would be enforceable as a trade secret or the copying of which
would be enjoined or restrained by a court as constituting unfair competition.

2. License Terms and Conditions.

     2.1 Grant of License.  Scripps  hereby  grants to  Licensee  an  exclusive,
worldwide  license,  without the right to sublicense,  to Scripps Technology and
under  Scripps  Patent  Rights,  to use the  Licensed  Process to make  Licensed
Product and to use and sell Licensed Product in the Field,  subject to the terms

non-exclusive license either (a) on the second anniversary of the Effective Date
if Licensee has failed to sell Licensed Product prior to such anniversary or (b)
on the fifth anniversary of the Effective Date.

     2.2  Royalties.  Licensee  shall pay to Scripps a  continuing  royalty on a
country-by-country basis in the amount of (i) seven percent (7%) of Net Sales of
Licensed  Product  which cannot be made,  used or sold in such  country  without
infringing  one or more valid claims under  Scripps  Patent Rights or (ii) three
and one-half percent (3.5%) of Net Sales of all other Licensed Product.

     2.3 Combination Products.

     2.3.1  Definition  of  Combination   Product.  As  used  herein,  the  term
"Combination   Product"   shall  mean  a  Licensed   Product   which  cannot  be
manufactured,  used or sold without infringing Scripps Patent Rights,  utilizing
Scripps  Technology  licensed  hereunder,  infringing  or utilizing  one or more
patents or  proprietary  technology  or know-how of (I)  Licensee,  (ii) a third
party licensed  pursuant to an agreement  between Licensee and such third party,
or (iii) Scripps under a license  agreement other than this Agreement  (referred
to herein as "other licensed rights").

     2.3.2  Royalty  Payable on  Combination  Products.  The royalty  payable on
Combination  Products  shall be the royalty rate set forth in Section 2.2. above
based 
<PAGE>

on  a  pro rata portion of Net Sales of Combination  Products in accordance with
the following formula:

                                                 A
                                            X = ---
                                                 B, where


                                            X = the  pro  rata  portion  of  Net
                                    Sales  attributable to Scripps Patent Rights
                                    or other Scripps Technology  licensed herein
                                    (expressed as a percentage), and

                                            A = the  fair  market  value  of the
                                    component   in   the   Combination   Product
                                    utilizing   Scripps   Technology    licensed
                                    hereunder, and

                                            B = A plus the fair market  value of
                                    all  other  components  in  the  Combination
                                    Product using other licensed rights.

The fair market values described above shall be determined by the parties hereto
in good faith. In the absence of agreement as to the fair market value of all of
the components contained in a Combination Product, the fair market value of each
component  shall be determined by arbitration in accordance  with the provisions
of Section 10.2 hereof.

     2.4 Quarterly  Payments.  With  regard to Net Sales made by Licensee or its
Affiliates,  royalties shall be payable by Licensee quarterly, within sixty (60)
days  after  the end of each  calendar  quarter,  based  upon  the Net  Sales of
Licensed  Product during such preceding  calendar  quarter,  commencing with the
calendar  quarter in which the first  commercial sale of any Licensed Product is
made.

     2.5 Term of  License.  Unless  terminated  sooner  in  accordance  with the
provisions  of this  Agreement,  the term of this license  shall expire when the
last of the  royalty  obligations  set forth has  expired.  Notwithstanding  the
foregoing,  if applicable government regulations require a shorter term and/or a
shorter term of  exclusivity  than  provided  for herein,  then the term of this
License  Agreement  shall be so  shortened or this  License  Agreement  shall be
amended to provide for a non-exclusive  license, and, in such event, the parties
shall negotiate in good faith to reduce  appropriately  the royalties payable as
set forth under the section heading "Royalties" hereof.

     2.6 Duration of Royalty Obligations. The royalty obligations of Licensee as
to  each  Licensed  Product  shall  terminate  on  a  country-by-country   basis
concurrently  with the expiration of the last to expire of Scripps Patent Rights
utilized by or in such Licensed Product in each such country or, with respect to
Licensed Product not utilizing

                                       4

<PAGE>
any Scripps Patent Rights, fifteen (15) years after the date of first commercial
sale of such Licensed Product in such country.

     2.7  Reports.  Licensee  shall  furnish to Scripps at the same time as each
royalty payment is made by Licensee,  a detailed  written report of Net Sales of
the  Licensed  Product  and the royalty  due and  payable  thereon,  including a
description   of   any   offsets   or   credits   deducted   therefrom,   on   a
product-by-product and  country-by-country  basis, for the calendar quarter upon
which the royalty payment is based.

     2.8 Records. Licensee shall keep, and cause its Affiliates and sublicensees
to keep, full, complete and proper records and accounts of all sales of Licensed
Product in  sufficient  detail to enable the  royalties  payable on Net Sales of
each Licensed Product to be determined.  Scripps shall have the right to appoint
an independent  certified  public  accounting  firm approved by Licensee,  which
approval shall not be unreasonably  withheld,  to audit the records of Licensee,
its Affiliates  and  sublicensees  as necessary to verify the royalties  payable
pursuant to this Agreement.  Licensee, its Affiliates and sublicensees shall pay
to Scripps  an amount  equal to any  additional  royalties  to which  Scripps is
entitled as disclosed by the audit, plus interest thereon at the rate of one and
one-half  percent  (1.5%) per month.  Such audit shall be at Scripps's  expense;
provided,  however,  that if the audit  discloses  that  Scripps  was  underpaid
royalties with respect to any Licensed Product by at least five percent (5%) for
any calendar quarter, then Licensee, its Affiliates or sublicensee,  as the case
may be, shall reimburse  Scripps for any such audit costs.  Scripps may exercise
its right of audit as to each of Licensee,  its  Affiliates or  sublicensees  no
more  frequently  than once in any  calendar  year.  The  accounting  firm shall
disclose to Scripps  only  information  relating to the  accuracy of the royalty
payments.  Licensee, its Affiliates and sublicensees shall preserve and maintain
all such  records  required  for audit for a period of three (3) years after the
calendar quarter to which the record applies.

     2.9 Foreign Sales. The remittance of royalties payable on sales outside the
United States, if sold in other than United States Dollars,  shall be payable to
Scripps in United States Dollar  equivalents at the official rate of exchange of
the currency of the country from which the royalties  are payable,  as quoted in
the Wall Street  Journal for the last  business day of the  calendar  quarter in
which the royalties are payable.  If the transfer of or the conversion  into the
United States Dollar  equivalents of any such remittance in any such instance is
not  lawful  or  possible,  the  payment  of such  part of the  royalties  as is
necessary  shall be made by the deposit  thereof,  in the currency of the county
where the sale was made on which the royalty was based to the credit and account
of Scripps or its nominee in any  commercial  bank or trust company of Scripps's
choice located in that country, prompt written notice of which shall be given by
Licensee to Scripps.

     2.10 Foreign  Taxes.  Any tax required to be withheld by Licensee under the
laws of any foreign  country for the accounts of Scripps  shall be promptly paid
by  Licensee  for and on  behalf  of  Scripps  to the  appropriate  governmental
authority, and Licensee

                                       5

<PAGE>
shall use its best efforts to furnish  Scripps with proof of payment of such tax
together with official or other  appropriate  evidence  issued by the applicable
government  authority.  Any such tax actually paid on Scripps's  behalf shall be
deducted from royalty payments due Scripps.

3. Patent Matters.

     3.1 Patent  Prosecution  and  Maintenance.  From and after the date of this
Agreement,  the provisions of this Section 3 shall control the  prosecution  and
maintenance of any patent included within Scripps Patent Rights.  Subject to the
requirements,  limitations and conditions set forth in this  Agreement,  Scripps
shall  direct and control (I) the  preparation,  filing and  prosecution  of the
United  States and foreign  patent  applications  within  Scripps  Patent Rights
(including  any  interferences  and foreign  oppositions)  and (ii) maintain the
patents issuing therefrom.

     3.2 Ownership.  The patent  applications  filed and the patents obtained by
Scripps  pursuant  to  Section  3.1  hereof  shall be owned  solely by  Scripps,
assigned to Scripps and deemed a part of Scripps Patent Rights.

4. Obligations Related to Commercialization.

     4.1  Commercial  Development  Obligation.  In order to maintain the license
granted  hereunder  in force,  Licensee  shall use  reasonable  efforts  and due
diligence to develop  Scripps  Technology  and Scripps  Patent  Rights which are
licensed hereunder into commercially  viable Licensed Product, as promptly as is
reasonably  and  commercially  feasible,  and  thereafter  to  produce  and sell
reasonable quantities of Licensed Product. Licensee shall keep Scripps generally
informed as to Licensee's  progress in such  development,  production  and sale,
including its efforts,  if any, to  sublicense  Scripps  Technology  and Scripps
Patent Rights,  and Licensee shall deliver to Scripps a quarterly written report
and such other reports as Scripps may  reasonably  request.  The parties  hereto
acknowledge and agree that achievement of the milestones  described in Exhibit A
attached  hereto on or before the dates set forth  therein  shall be evidence of
compliance by Licensee with its commercial development obligations hereunder for
the time periods  specified in Exhibit A. In the event  Scripps has a reasonable
basis to believe that Licensee is not using reasonable efforts and due diligence
as required  hereunder,  upon notice by Scripps to Licensee which  specifies the
basis for such  belief,  Scripps and Licensee  shall  negotiate in good faith to
attempt to mutually  resolve the issue. In the event Scripps and Licensee cannot
agree upon any matter related to Licensee's commercial development  obligations,
the parties  agree to utilize  arbitration  pursuant  to Section  10.2 hereof in
order to resolve the matter. If the arbitrator  determines that Licensee has not
complied  with its  obligations  hereunder,  and such default is not fully cured
within sixty (60) days after the  arbitrator's  decision,  Scripps may terminate
Licensee's rights under this Agreement.

                                       6
<PAGE>
     4.2  Governmental  Approvals and Marketing of Licensed  Products.  Licensee
shall be responsible for obtaining all necessary  governmental approvals for the
development,  production, distribution, sale and use of any Licensed Product, at
Licensee's expense, including,  without limitation, any safety studies. Licensee
shall  have  sole   responsibility   for  any  warning  labels,   packaging  and
instructions  as to the use of Licensed  Product and for the quality control for
any Licensed Product.

     4.3  Indemnity.  Licensee  hereby  agrees  to  indemnify,  defend  and hold
harmless Scripps and any parent, subsidiary or other affiliated entity and their
trustees,  officers,  employees,  scientists  and agents  from and  against  any
liability or expense  arising from any product  liability  claim asserted by any
party as to any  Licensed  Product  or any  claims  arising  from the use of any
Scripps Patent Rights or Scripps  Technology  pursuant to this  Agreement.  Such
indemnity and defense  obligation shall apply to any product  liability or other
claims, including without limitation, personal injury, death or property damage,
made by employees, subcontractors,  sublicensees, or agents of Licensee, as well
as any member of the general public. Licensee shall use its best efforts to have
Scripps  and any  parent,  subsidiary  or  other  affiliated  entity  and  their
trustees, officers, employees, scientists and agents named as additional insured
parties on any product liability insurance policies maintained by Licensee,  its
Affiliates and sublicensees applicable to Licensed Products.

     4.4 Patent  Marking.  To the extent  required by applicable  law,  Licensee
shall mark all Licensed  Products or their  containers  in  accordance  with the
applicable patent marking laws.

     4.5 No Use of Name. The use of the name "The Scripps  Research  Institute",
"Scripps",  or any variation  thereof in connection with the advertising or sale
of Licensed Products is expressly prohibited.

     4.6 U.S.  Manufacture.  To the extent required by applicable  United States
laws, if at all,  Licensee agrees that Licensed Products will be manufactured in
the  United  States,  or its  territories,  subject  to such  waivers  as may be
required,  or obtained,  if at all, from the United States  Department of Health
and Human Services, or its designee.

     4.7 Foreign  Registration.  Licensee agrees to register this Agreement with
any foreign  governmental agency which requires such registration,  and Licensee

Licensee shall assure that all foreign laws affecting this Agreement or the sale
of Licensed Products are fully satisfied.

     5. Limited  Warranty.  Scripps  hereby  represents and warrants that it has
full  right  and  power to enter  into this  Agreement.  SCRIPPS  MAKES NO OTHER
WARRANTIES  CONCERNING  SCRIPPS PATENT RIGHTS OR SCRIPPS  TECHNOLOGY  COVERED BY

<PAGE>



Licensee's interest shall expressly assume in writing the performance of all the
terms and conditions of this Agreement to be performed by Licensee.

10. General Provisions.

     10.1 Independent Contractors. The relationship between Scripps and Licensee
is  that  of  independent  contractors.  Scripps  and  Licensee  are  not  joint
venturers,  partners,  principal  and agent,  master and  servant,  employer  or
employee,  and have no other  relationship  other than  independent  contracting
parties. Scripps and Licensee shall have no power to bind or obligate each other
in any manner, other than as is expressly set forth in this Agreement.

     10.2  Arbitration.  Any  controversy or claim arising out of or relating to
this Agreement,  or the breach thereof,  shall be settled by binding arbitration
in accordance with the Commercial  Arbitration Rules of the American Arbitration
Association  ("AAA"),  and the procedures  set forth below.  In the event of any
inconsistency  between the Rules of AAA and the procedures set forth below,  the
procedures  set forth below shall  control.  Judgment upon the award rendered by
the arbitrators may be enforced in any court having jurisdiction thereof.

     10.2.1 Location.  The location of the arbitration shall be in the County of
San Diego.

     10.2.2  Selection of Arbitrators.  The arbitration  shall be conducted by a
panel of three neutral  arbitrators who are independent and  disinterested  with
respect to the parties, this Agreement, and the outcome of the arbitration. Each
party  shall  appoint  one  neutral  arbitrator,  and these two  arbitrators  so
selected by the parties shall then select the third arbitrator. If one party has
given  written  notice to the other party as to the  identity of the  arbitrator
appointed by the party,  and the party  thereafter makes a written demand on the
other party to appoint its designated  arbitrator  within the next ten days, and
the other party fails to appoint its designated arbitrator within ten days after
receiving  said  written  demand,  then  the  arbitrator  who has  already  been
designated shall appoint the other two arbitrators.

     10.2.3  Discovery.  Unless the  parties  mutually  agree in writing to some
additional and specific pre-hearing  discovery,  the only pre-hearing  discovery
shall be (a)  reasonably  limited  production  of  relevant  and  non-privileged
documents,  and (b) the identification of witnesses to be called at the hearing,
which identification  shall give the witness's name, general  qualifications and
position,  and a brief  statement as to the general scope of the testimony to be
given by the  witness.  The  arbitrators  shall  decide any  disputes  and shall
control the process concerning these pre-hearing discovery matters.  Pursuant to
the  Rules  of AAA,  the  parties  may  subpoena  witnesses  and  documents  for
presentation at the hearing.

                                       11

<PAGE>



     10.2.4 Case  Management.  Prompt  resolution of any dispute is important to
both parties; and the parties agree that the arbitration of any dispute shall be
conducted  expeditiously.  The arbitrators are instructed and directed to assume
case management  initiative and control over the arbitration  process (including
scheduling of events,  pre-hearing discovery and activities,  and the conduct of
the  hearing),  in order to complete  the  arbitration  as  expeditiously  as is
reasonably practical for obtaining a just resolution of the dispute.

     10.2.5 Remedies. The arbitrators may grant any legal or equitable remedy or
relief that the  arbitrators  deem just and  equitable,  to the same extent that
remedies  or relief  could be  granted  by a state or  federal  court,  provided
however,  that no  punitive  damages  may be  awarded.  No court  action  may be
maintained  seeking  punitive  damages.  The  decision  of any two of the  three
arbitrators appointed shall be binding upon the parties.

     10.2.6   Expenses.   The  expenses  of  the   arbitration,   including  the
arbitrators'  fees,  expert witness fees, and attorney's fees, may be awarded to
the  prevailing  party,  in  the  discretion  of  the  arbitrators,  or  may  be
apportioned  between  the  parties  in  any  manner  deemed  appropriate  by the
arbitrators.  Unless and until the  arbitrators  decide that one party is to pay
for all (or a share) of such  expenses,  both parties shall share equally in the
payment of the arbitrators' fees as and when billed by the arbitrators.

     10.2.7  Confidentiality.  Except as set forth below, the parties shall keep
confidential the fact of the arbitration,  the dispute being arbitrated, and the
decision of the  arbitrators.  Notwithstanding  the  foregoing,  the parties may
disclose  information  about the arbitration to persons who have a need to know,
such  as  directors,   trustees,   management  employees,   witnesses,  experts,
investors,  attorneys,  lenders,  insurers,  and  others  who  may  be  directly
affected. Additionally, if a party has stock which is publicly traded, the party
may make  such  disclosures  as are  required  by  applicable  securities  laws.
Further, if a party is expressly asked by a third party about the dispute or the
arbitration, the party may disclose and acknowledge in general and limited terms
that  there is a  dispute  with the  other  party  which is being  (or has been)
arbitrated.  Once the  arbitration  award has become final,  if the  arbitration
award is not promptly satisfied, then these confidentiality  provisions shall no
longer be applicable.

     10.3 Entire Agreement;  Modification.  This Agreement sets forth the entire
agreement and understanding between the parties as to the subject matter hereof.
There shall be no amendments or  modifications  to this  Agreement,  except by a
written document which is signed by both parties.

     10.4  California  Law.  This  Agreement  shall be construed and enforced in
accordance with the laws of the State of California.

Agreement be held invalid or unenforceable by a court of competent jurisdiction,

effort to  replace  any  invalid  or  unenforceable  provision  with a valid and
enforceable one such that the objectives contemplated by them when entering this
Agreement may be realized.

constitute  a waiver of such  party's  rights to the future  enforcement  of its
rights under this Agreement,  excepting only as to an express written and signed

waiving any of its rights,  shall have the right, power, and authority,  without
notice, presentment or demand to declare the unpaid principal amount of the Note
and any other indebtedness secured hereby, whether matured or not, together with
any interest thereon accrued and unpaid, to be immediately due and payable,  and
such indebtedness and interest shall thereupon become and be immediately due and

<PAGE>



         payments  shall  be  a complete release and discharge of the obligor or
         obligors thereof to the extent of the payment or payments so made;

                  (2) to exercise all the rights, remedies and privileges of the
         Debtor arising from the Collateral, or any party thereof, including the
         compromising,   waiving,  excusing,  or  in  any  manner  releasing  or

                  (4) receive,  and the Debtor will  forthwith  surrender to the
         Secured  Party,  the possession of the  Collateral,  and, to the extent
         permitted by law, the Secured  Party may itself or by such  officers or
         agents as it may appoint (A) manage or operate  the  Collateral  or any
         part  thereof,   (B)  exclude  the  Debtor,  its  agents  and  servants
         therefrom, (C) fix or modify purchase prices, and lease the Property or
         Personal Property,  or any part thereof, and (D) do all acts, including
         the making of contracts,  which the Secured  Party deems  necessary for
         the care or management of the Property or Personal Property; and

                  (5)  sue or otherwise collect and receive money.

         b. The Secured  Party may  foreclose  this  Security  Agreement  in the
manner now or hereafter provided or permitted by law, including treatment of the
Collateral as real property subject to judicial  foreclosure pursuant to Chapter
667, Hawaii Revised Statutes,  as amended, and shall have the immediate right to
receivership  on ex parte order and without  bond pending  foreclosure,  and may
sell,  assign,  transfer or  otherwise  dispose of the  Collateral  at public or
private sale, in whole or in part, and the Secured Party may, in its own name or
as the irrevocably appointed  attorney-in-fact of the Debtor, effectually assign
and transfer the Collateral,  or any part thereof,  absolutely,  and execute and
deliver all necessary assignments,  deeds, conveyances,  bills of sale and other
instruments  with power to substitute one or more persons or  corporations  with
like power; and, if the Secured Party so instructs the Debtor,  the Debtor shall
assemble,  without  expense to the Secured  Party,  all of the  Collateral  at a
convenient  place on the island  where the  Property is located,  and the Debtor
shall  ratify and confirm any such sale or  transfer  by  delivering  all proper
instruments  to such persons or  corporations  as may be  designated in any such
request. Any such foreclosure sale,  assignment or transfer shall, to the extent
permitted  by law, be a perpetual  bar,  both at law and in equity,  against the
Debtor and all persons and entities lawfully claiming by or through or under the
Debtor.  Any such sale may be adjourned  from time to time.  Upon any sale,  the
Secured Party may bid for and purchase the Collateral,  or any part thereof, and
upon compliance with the terms of sale, may hold, retain and possess and dispose
of the Collateral, in its absolute right without further accountability, and any
purchaser,  including the Secured  Party,  at any such sale may, if permitted by
law,  after  allowing for the proportion of the total purchase price required to
be  paid  in cash  for  the  costs  and  expenses  of the  sale,  commissioner's
compensation  and other charges,  in paying  purchase  money,  turn in the Note,
including interest and charges thereon,  in lieu of cash, up to the amount which
shall, upon distribution of the net proceeds of such sale, be payable thereon.

         c. In case of any Event of  Default,  neither  the  Debtor  nor  anyone
claiming by, through or under the Debtor,  to the extent the Debtor may lawfully
so  agree,  shall  or will  set up,  claim  or  seek  to take  advantage  of any
appraisement,  valuation,  stay, extension or redemption law now or hereafter in
force in any  locality  where  any of the  Collateral  is  situated  in order to
prevent or hinder the  enforcement of this Security  Agreement,  or the absolute
sale of the  Collateral,  or the  final and  absolute  putting  into  possession
thereof,  immediately after such sale, of the purchasers thereat; and the Debtor
in the Debtor's own right and for all who may claim under the

                                       -6-
<PAGE>
Debtor,  hereby  waives,  to the full extent that the Debtor may lawfully do so,
the benefit of all such laws and any and all right to have the estates comprised
in the security intended to be created hereby marshalled upon any enforcement of
the  lien  hereof  and  agrees  that  the  Secured  Party  or any  court  having
jurisdiction  to foreclose  such lien may sell the  Collateral in parts or as an
entirety.  The Secured  Party may apply the proceeds of any such sale first,  to
the costs and expenses of such sale and all proceedings in connection therewith,
including  counsel fees; next, to the payment of any  disbursements  made by the
Secured  Party for taxes or  assessments  or other charges prior to the Security
interest  of this  Security  Agreement  which the  Secured  Party  shall deem it
expedient to pay; next, to the repayment of any other  disbursements made by the
Secured Party according to the terms hereof;  next, to the payment of the unpaid
principal of and interest on the Note,  and any other  obligations of the Debtor
under the Loan Documents;  and the remainder,  if any, shall be paid over to the
Debtor.  If  such  proceeds  shall  be  insufficient  to  discharge  the  entire
indebtedness  owing  by the  Debtor  under  the  Security  Agreement,  the  Loan
Documents, and any other instrument or obligation secured hereunder, the Secured
Party may have any other legal recourse against the Debtor for the deficiency.

         d.  Nothing in this  Security  Agreement  or the Note shall  impair the
right, which is unconditional and absolute, of the holder of the Note to enforce
payment of the principal of, and interest on, the Note and all fees, charges and
other sums due under the Loan  documents at or after the date therein  expressed
as the date when the same shall  become  due,  or the  obligation  of the Debtor
secured  hereunder,  which is likewise  unconditional and absolute,  to pay such
amounts at the respective times and places therein expressed.

Secured Party as follows:

     1. Warranties Regarding the Collateral.  The Debtor warrants and represents
to the Secured Party as follows:

         Agreement.

                     Debtor's rights therein or thereto.

F. THE DEBTOR'S COVENANTS.  The Debtor hereby covenants and agrees with the
Secured Party as follows:

     1. Payment of Taxes,  Assessments,  etc. The Debtor will punctually pay and
discharge,  or  cause to be paid and  discharged  from  time to time as the same
shall become due, all taxes, rates, assessments,  impositions,  duties and other
charges of every description to which the Collateral,  or any part thereof,  may
during the term of this  Security  Agreement  become liable by authority of law,
the payment of which  shall be secured by this  Security  Agreement.  The Debtor
will,  upon request,  deposit  copies of the receipts  therefor with the Secured
Party at least

                                       -7-

impositions, duties and other charges may be paid without penalty.

     2. Indemnification. The Debtor will indemnify and hold and save the Secured
Party  harmless and against any and all  liability,  loss,  damage or expense of
whatever kind or nature, including reasonable attorneys' fees, which the Secured
Party may at any time sustain or incur hereunder, including, but not limited to,
any claims or demands whatsoever which may be asserted against the Secured Party
as a result of any  failure  on the part of the  Debtor to  perform,  observe or
discharge its obligations involving any of the Collateral. Prior to actual entry
and taking  possession  of any  property by the  Secured  Party,  this  Security
Agreement shall not operate to place  responsibility  upon the Secured Party for
the control,  care,  management or repair of any property  constituting security
hereunder.

     3. Duplicate  Originals.  At the request of the Secured  Party,  the Debtor
will furnish to the Secured Party a duplicate original of each material Contract
now existing or hereafter executed by the Debtor.

     4.  Litigation.  The  Debtor  will  appear  in and  defend  any  action  or
proceeding  at law or in  equity  affecting  in any  manner  all or  part of the
Collateral;  and in such event (except where the purported  defect affecting the
security  hereof  arises or  results  from any act or  omission  of the  Secured
Party),  the Debtor will pay all costs,  charges and expense,  including cost of
evidence  of title and  reasonable  attorneys'  fees  incurred,  and will  fully
indemnify  the  Secured  Party from and against  any loss,  damage,  or expense,
including reasonable attorneys' fees, sustained or incurred by the Secured Party
as a  result  of any  failure  on the  part of the  Debtor  to  comply  with its
obligations under this paragraph.

     5.  Liens.  The Debtor will  maintain  the valid  security  interest of the
Secured Party in the Collateral and the sums due  thereunder,  free and clear of
all liens,  claims,  and encumbrances that may be, or are threatened to be, made
prior to or on a parity with the security  interest of the Secured Party herein,
except liens for taxes or assessments not yet payable or payable without penalty
so long as payable.  The Debtor will not claim any credit on interest payable on
the Note or on any other  payment  secured  hereby for any  portion of the taxes
assessed  against the  Collateral,  and the  provisions of any law entitling the
Debtor to such  credit are hereby  expressly  waived by the Debtor to the extent
they may be lawfully waived.

     6. Further  Assurances.  The Debtor will assist in the  preparation  of and
execute and acknowledge  from time to time, alone or with the Secured Party, and
deliver, file or record any further instruments,  including security agreements,
financing or continuation  statements,  mortgages or other  instruments,  and do
such  further  acts as the  Secured  Party may  request to  confirm,  establish,
continue,  maintain  and perfect the  security  interest of the  Security  Party
created by this  Security  Agreement  and to subject the  Collateral to the lien
hereof,  including  all  renewals,  additions,  substitutions,  replacements  or
betterments  thereto and all proceeds  therefrom,  and  otherwise to protect the
same against the rights and interests of third parties,  the Debtor  agreeing to
pay the cost of preparing, filing and recording the same.

     7.  Acknowledgment of Debt. The Debtor,  within five (5) days after request
by the Secured Party in writing,  will furnish to the Secured  Party,  or to any
proposed  assignee  of  this  Security  Agreement,   a  written  statement  duly
acknowledged  of the amount due under this Security  Agreement and the Note, and
whether any offsets, counterclaims or defenses exist against the secured debt.

     8. Personal Property.  The Debtor agrees: (a) to keep all Personal Property
intact  and in good  condition,  order  and  repair  reasonable  wear  and  tear
excepted; (b) at the Debtor's own expense to replace any

                                       -8-

<PAGE>
portion  thereof which may be broken or become obsolete or worn out or unfit for
use; (c) to comply with all laws,  rules and  regulations  made by  governmental
authority and applicable thereto; (d) not to commit or suffer any strip or waste
of the Personal Property; and (e) not to alienate,  assign, pledge, transfer, or
encumber any of the rights or interests of the Debtor therein and thereto.

     9. Insurance. The Debtor will, during the terms of this Security Agreement,
keep all of the Personal  Property insured against hazards of such type or types
and in such amount or amounts  and form of policy as the Secured  Party may from
time to time  reasonably  require and will  provide  copies of the  premiums and
costs of all insurance required hereunder and, upon demand of the Secured Party,
will furnish  evidence of payment of such  premiums.  The debtor,  not less than
twenty (20) days prior to the expiration  date of each policy,  shall deliver to
the Secured Party a copy of renewal policy or policies,  accompanied by evidence
of payment  satisfactory to the Secured Party. All insurance  required hereunder
shall be  effected  under valid and  enforceable  policies  issued by  insurance
companies  authorized  to do business in the State of Hawaii,  the Debtor hereby
acknowledging  receipt of written  notice from the Secured Party that the Debtor
is free to procure any such insurance from any insurance  company so authorized.
The  Secured  Party  shall  not be  responsible  for such  insurance  or for the
collection  of any  insurance  moneys,  or for the  insolvency of any insurer or
insurance  underwriter.  The amount  collected from any fire or other  insurance
policy may be applied by the Secured Party upon any indebtedness  secured hereby
and in such order as the Secured Party may  determine,  or, at the option of the
Secured  Party,  the entire  amount so collected,  or any part  thereof,  may be
applied to the restoration of the Personal Property,  or released to the Debtor,
without being deemed a payment on any of the indebtedness  secured hereby.  Such
application  or release shall not cure or waive any default or notice of default
hereunder or invalidate  any act done pursuant to such notice.  No lien upon any
of such policies of insurance, or upon any refund or return premium which may be
payable on the  cancellation  or termination  thereof,  shall be given to anyone
other  than the  Secured  Party,  except by proper  endorsement  affixed to such
policy and  approved  by the  Secured  Party.  In the event of loss or  physical
damage to the Personal Property,  the Debtor shall give immediate notice thereof
by mail to the Secured  Party,  and the Secured  Party may make proof of loss if
the same is not made promptly by the Debtor. In the event of foreclosure of this
Security  Agreement,  or  other  transfer  of  title  to the  Collateral  in the
extinguishment of the indebtedness secured hereby, all right, title and interest
of the Debtor in and to any  insurance  policies then in force shall pass to the
purchaser  or the  grantee.  All  such  policies  or  other  contracts  for such
insurance issued by the respective insurers shall, to the extent obtainable,  be
without  contribution and contain an agreement by the insurer that the policy or
other  contract  shall not be cancelled or materially  changed  without at least
thirty (30) days', prior written notice to the Secured Party.

     10. No Violation of Forfeiture  Laws. The Debtor  warrants and covenants as
follows:

         a.  The  Debtor  will  not  violate  any  federal,   state,   or  other
governmental law, including but not limited to 18 U.S.C. ss.1956(a)(3), that may
in any way  affect  or  impair  the value of the  Collateral  or the  properties
covered by the security  instruments which are part of the Loan Documents or the
Secured Party's priority therein;

         b. To the best of the Debtor's  knowledge,  there has been no violation
of any federal,  state,  or other law  affecting  or impairing  the value of the
Collateral or the properties covered by the security  instruments which are part
of the Loan Documents; and

         c. The  Debtor  shall make  every  good  faith  effort to  prevent  any
violation of any federal,  state, or other  governmental law,  including but not
limited  to 18 U.S.C.  ss.1956(a)(3),  that may in any way  affect or impair the
value of the  Collateral or the properties  covered by the security  instruments
which are part of the Loan Documents or the Secured Party's priority therein.

<PAGE>
         In the event that the  Secured  Party has  reasonable  cause to believe
that any portion of the Collateral or any other property or collateral  securing
the Loan might be or become subject to forfeiture  under the foregoing laws, the
Debtor agrees that the Secured Party may, in its sole  discretion,  and addition
to its other remedies  under this  Agreement and at law or in equity,  refuse to
make any further disbursements of Loan proceeds,  of any kind whatsoever,  until
the Secured  Party no longer has any  reasonable  belief that any portion of the
Collateral or any other  property or collateral  securing the Loan is subject to
or may become subject to forfeiture under any of the foregoing laws.

G. MUTUAL COVENANTS. The Debtor and the Secured Party mutually covenant and
agree each with the other as follows:

     1. The Secured  Party Not Obligated to Perform.  Neither the  acceptance of
this  Security  Agreement by the Secured  Party,  nor the exercise of any rights
hereunder by the Secured  Party,  shall be construed in any way as an assumption
by the  Secured  Party of any  obligations,  responsibilities  or  duties of the
Debtor  arising from the  collateral  assigned  hereunder or otherwise  bind the
Secured Party to the performance of any of the terms and provisions contained in
any obligations  respecting the Personal Property, it being expressly understood
that the Secured  Party shall not be obligated to perform,  observe or discharge
any  obligation,  responsibility,  duty, or liability of the Debtor under any of
the  Collateral,  including,  but not limited to,  appearing in or defending any
action, expending any money or incurring any expenses in connection herewith.

     2. Right of the Secured  Party to Defend  Action  Affecting  Security.  The
Secured Party may, at the Debtor's  expense,  appear in and defend any action or
proceeding at law or in equity purporting to affect the Secured Party's security
interest under this Security Agreement.

     3. Right of the Secured Party to Prevent or Remedy  Default.  If the Debtor
shall fail to perform any of the covenants,  conditions and agreements  required
to be performed and observed by the Debtor under the Loan  Documents,  including
this Security Agreement,  or any other instruments secured hereby, or in respect
of the Personal  Property,  the Secured Party (a) may but shall not be obligated
to take action the Secured  Party deems  necessary  or  desirable  to prevent or
remedy any such  default  by the Debtor or  otherwise  to protect  the  security
interest of the Secured Party under this Security Agreement,  and (b) shall have
the absolute and immediate  right to enter in and upon or take possession of the
Property,  Collateral  or any part  thereof  to such  extent and as often as the
Secured Party, in its sole discretion,  deems necessary or desirable in order to
prevent or to cure any such  default by the Debtor,  or otherwise to protect the
security of this  Security  Agreement.  The Secured  Party may advance or expend
such sums of money for the  account of the Debtor,  as the Secured  Party in its
sole discretion deems necessary for any such purpose.

     4. The Secured Party's Expenses. All reasonable advances,  costs, expenses,
charges and attorneys' fees which the Secured Party may make, pay or incur under
any provision of this Security  Agreement for the  protection of its security or
for  the  enforcement  of  any  of  its  rights  hereunder,  or  in  foreclosure
proceedings  commenced  and  subsequently   abandoned,  or  in  any  dispute  or
litigation  in which the  Secured  Party or the  holder  of the Note may  become
involved  by reason of or  arising  out of the Loan  Documents,  including  this
Security Agreement, or any other instrument secured hereby, or the Collateral or
the care and  management of the  Collateral,  shall be paid by the Debtor to the
Secured  Party,  upon  demand,  and shall bear  interest  until paid at the rate
specified  by the Note to be paid in the  event of  default  thereunder,  all of
which obligations shall be additional charges upon the Collateral and be equally
secured hereby.


                                      -10-

<PAGE>



     5. The Secured  Party's  Right of Set-Off.  Upon the happening of any event
entitling  the Secured  Party to pursue any remedy  provided  herein,  or if the
Secured Party shall be served with  garnishee  process in which the Debtor shall
be named as defendant,  whether or not the Debtor shall be in default  hereunder
at the time,  the Secured  Party may,  but shall not be required to, set off any
indebtedness  owing by the Secured Party to the Debtor against any  indebtedness
secured hereby,  without first  resorting to the security  hereunder and without
prejudice to any other  rights or remedies of the Secured  Party or its security
interest herein.

     6. No Waiver. In case the Secured Party shall have proceeded to enforce any
right or remedy hereunder and such proceedings  shall have been  discontinued or
abandoned  for any reason,  then in every such case,  the Debtor and the Secured
Party shall be restored to their  former  positions  and rights  hereunder  with
respect to the  Collateral,  and all rights,  remedies and powers of the Secured
Party shall  continue  as if no such  proceeding  had been taken.  No failure or
delay on the part of the Secured Party in exercising any right,  remedy or power
under this Security  Agreement or in giving or insisting upon strict performance
by the Debtor  hereunder or in giving notice hereunder shall operate as a waiver
of the same or any other  power or right,  and no single or partial  exercise of
any such power or right shall preclude  another or further  exercise  thereof or
the   exercise  of  any  other  such  power  or  right.   The   Secured   Party,
notwithstanding any such failure, shall have the right thereafter to insist upon
the strict  performance by the Debtor of any and all of the terms and provisions
of this Security  Agreement to be performed by the Debtor.  The  collection  and
application of proceeds,  the entering and taking  possession of the Collateral,
and the  exercise  of the  rights of the  Secured  Party  contained  in the Loan
Documents,  including  this  Security  Agreement,  shall  not cure or waive  any
default,  or affect any notice of default,  or invalidate any acts done pursuant
to such notice. No waiver by the Secured Party of any breach or default of or by
any party  hereunder,  shall be deemed to alter or affect  the  Secured  Party's
rights hereunder with respect to any prior or subsequent defaults.

     7.  Remedies.  No right or remedy  herein  reserved to the Secured Party is
intended to be exclusive  of any other right or remedy,  but each and every such
remedy shall be cumulative and is not in lieu of but shall be in addition to any
other rights or remedies given under this Security Agreement. Any and all of the
Secured  Party's  rights and remedies may be exercised  from time to time and as
often as such exercise is deemed necessary or desirable by the Secured Party.

     8.  Right of the  Secured  Party to  Extend  Time of  Payment,  Substitute,
Release Security, etc. Without affecting the liability of any person,  including
the Debtor,  for the payment of any indebtedness  secured hereby, or the lien of
this Security  Agreement on the Collateral,  or the remainder  thereof,  for the
full amount of any indebtedness unpaid, the Secured Party may from time to time,
without  notice or without  affecting  or impairing  any of the Secured  Party's
rights under this Security Agreement:

         (a) release  any  person  liable  for  the  payment  of  any  of  the
indebtedness,

         (b) extend the time or  otherwise  alter the terms of payment of any of
the indebtedness or accept a renewal Note or Notes to evidence such an extension
or alteration,

         (c) accept  payments or prepayments of principal  without  reducing the
aggregate amount secured by this Agreement,  and make subsequent advances to the
Debtor up to the amount described herein;

         (d) accept additional security therefor of any kind, including (but not
limited to) deeds of trust or mortgages,


                                      -11-

<PAGE>
         (e) alter,  substitute  or  release  from any security interest or lien
held by the Secured Party any property securing the indebtedness,

         (f) resort  for  the  payment of the indebtedness secured hereby to its
several securities therefor in such order and manner as it may deem fit,

         (g) join in granting any easement  or creating any restriction thereon,
or

         (h) join in any extension,  subordination or other agreement  affecting
this Security Agreement or the lien or charge thereof.

(1) For the year ended March 31, 1998,  warrants and options to purchase  Common
Stock shares of the Company and convertible  preferred  stock were  outstanding,

TO OUR STOCKHOLDERS

Fiscal 1998 was a profound  disappointment  for Cyanotech  after years of steady
growth.  But it was  principally  attributable  to  reduced  sales  to a  single
Spirulina purchaser,  which had been the Company's largest customer,  accounting
for 34% of total  sales in FY97 vs.  5% in FY98.  These  figures  show  both the
opportunity  and the problem of relying on a single  product and  customer.  The
customer is a network  marketer  whose sales in China were halted by the Chinese
government  for much of the past fiscal  year along with all  network  marketers
there, then banned altogether. As a result,  Cyanotech's sales decreased to $7.6
million in FY98 from $11.4  million in FY97 with a net loss of  $300,000 in FY98
vs. net  income of $4.2  million in FY97.  To return to  profitability  at lower
demand  levels,  we  reduced  our  workforce  by 25% in the fourth  quarter.  By
contrast, fiscal 1999 and future years look more positive due to the variety and
potential of products on the market and under development.

SPIRULINA PACIFICA(TM)
         With the reduced sales to China,  we worked hard during FY98 to broaden
our customer base for  Spirulina.  An indicator of progress is our  relationship
with the General  Nutrition  Center (GNC) chain of retail  stores in the U.S. We
are now selling our branded Nutrex(TM) Spirulina Pacifica products through 1,000
GNC stores nationwide, up from 200 stores at the beginning of FY98. We also have
increased marketing efforts in Hawaii, signed additional  distributors overseas,
and are  investigating  new markets,  such as in poultry feed where  preliminary
studies indicate that Spirulina  contributes to a significantly  improved immune
system in poultry with the possibility of eliminating antibiotics. The Spirulina
market  overall is not large,  but we are working to increase our already strong
share.

NATUROSE(TM) ASTAXANTHIN
         We hoped that NatuRose would be used by the  aquaculture  industry from
its  introduction  in March 1997,  but we did not account for the close customer
relationships  in a market  characterized  by a single  supplier and the caution
shown in  accepting a new  product.  During  FY98,  prospective  customers in 12
countries  engaged in more than 30 feeding trials of NatuRose with all completed
studies to date showing positive results. Although we only sold trial quantities
of astaxanthin  during the fiscal year,  commercial  order flow has begun in the
first  quarter  of  FY99.  We  also  have  signed  a  Letter  of  Intent  with a
multi-national  life  sciences  company ($15 billion in annual sales to 150-plus
countries) to distribute  NatuRose,  initially to its  aquaculture  customers in
Europe.

MOSQUITOCIDE
         Once NatuRose was launched in 1997, we turned our development attention
to the  promising  potential  mosquitocide  we had  licensed  in FY 96 from  the
University  of  Memphis.  In the  summer  of 1997,  we hired a senior  molecular
biologist  experienced  in  natural  bacterial  toxins to lead the  mosquitocide
effort.  The original genetically engineered microalgae we had licensed included
only one of the four BTI toxins,  all of which are harmless to humans but deadly

                                       2
<PAGE>

to mosquito  larvae.  We are currently  focused on adding up to three additional
Bti toxins to  significantly  increase the product's  toxicity and to lessen the
risk of mosquito larvae evolving a resistance to a single-toxin product. We plan
to have the mosquitocide in limited commercial  production for worldwide testing
by the end of the current fiscal year.  The market  potential is unknown at this
time, but the need for safe-for-human  biopesticides is growing as the incidence
of  mosquito-borne  malarial and other diseases is increasing in both developing
and developed countries.

SCRIPPS ALDOLASE ANTIBODY
         In April  1998,  we  signed an  exclusive  agreement  with The  Scripps
Research  Institute  to produce  the  Institute's  patented  aldolase  catalytic
antibody 38C2 in microalgae.  Previously, the antibody has only been produced in
small quantities in animal cells in the laboratory. We have long maintained that
microalgae  provide an  excellent  vehicle for the genetic  engineering  of many
products due to their ease of genetic manipulation,  short generation cycles and
cellular   uniformity.   This  product  with  potential  for   applications   in
pharmaceuticals, fine chemicals and agriculture exemplifies our thesis.

ROBUST PRODUCT PIPELINE
         There  are over  30,000  species  of  microalgae,  many of  which  have
natural,  beneficial  properties  that can be  extracted  to produce  high-value
products,   while  many  more  can  act  effectively  as  vehicles  for  genetic
engineering to produce other products.  Our challenge is to remain focused as we
explore  the  wealth of  possibilities  and to  dedicate  our  efforts  to those
products with the clear and present  potential of success for the benefit of our
stockholders.  Cyanotech's product pipeline,  as shown on page 1 of this report,
is truly  robust  and varied -- a major  advance  from just a few years ago when
Spirulina was our only major  product.  Now Spirulina is among the products with
lesser  potential  in terms of overall  market  size and  possible  sales in the
future.

LOOKING AHEAD
         The hardest thing we had to do in fiscal 1998 was to lay off 25% of our
dedicated workforce in Kona. We deeply appreciate their  under-standing and look
forward to resuming our role as a steady employer in the region.  We commend the
fine work of all our  associates,  past and  present,  in helping run a reliable
operation with excellent  quality  control while  developing the significant new
products in our  pipeline.  We thank our  stockholders  for their  understanding
during a difficult period and our Board of Directors for supportive  counsel. In
brief,  we have  proven  the  process  of  producing  high-value  products  from
microalgae and are  developing a promising line of products.  We look forward to
increased sales and a return to our traditionally higher margins.

Fiscal 1998 Compared to Fiscal 1997

                           Net Sales
                  Net sales for the year ended March 31, 1998 were $7,627,000, a
                  decrease of 33.1% from net sales of  $11,399,000  for the year
                  ended March 31,  1997.  The  decrease in net sales  during the
                  year ended March 31, 1998 is  primarily  due to lower sales of
                  Spirulina  packaged consumer products to our largest customer,
                  a Hong Kong-based  network  marketing  company which purchased
                  our packaged  consumer products for sale under a private label
                  through their  marketing  organization,  primarily in mainland
                  China.  This  customer  experienced  a  delay  in  its  annual
                  recertification  process  by the  Chinese  government  and was
                  restricted by local governmental  authorities from hosting any
                  large  scale  distributor  meetings  from March  1997  through
                  September 1997. These regulatory  factors  adversely  impacted
                  our  customer's  ability  to  sell  and,  consequently,   this
                  customer's  need  for  our  packaged   consumer  products  was
                  severely  reduced.  For the year ended  March 31,  1998,  this
                  customer  accounted for less than 5% of Cyanotech's net sales,
                  down from  approximately 34% and 29% of net sales in the years
                  ended March 31, 1997 and 1996, respectively. Subsequent to the
                  end of fiscal 1998,  the Chinese  government  imposed a ban on
                  all network market  organizations,  effective October 1, 1998.
                  Future sales to this customer are expected to be minimal. Also
                  contributing  to the decline were lower  shipments (11% lower)
                  and lower average selling prices (2% lower) for bulk Spirulina
                  powder.

                           Gross Profit
                  Gross profit represents net sales less the cost of goods sold,
                  which includes the cost of materials,  manufacturing  overhead
                  costs,    direct   labor   expenses   and   depreciation   and
                  amortization. Gross profit decreased to 41.1% of net sales for
                  the year ended March 31, 1998, from 59.7% of net sales for the
                  year ended March 31, 1997.  This decrease in gross profit from
                  the prior  year is  primarily  attributable  to a shift in the
                  product mix to greater  sales of lower  priced bulk  Spirulina
                  products  (78% of net sales in fiscal 1998, up from 58% of net
                  sales in fiscal 1997), Spirulina production inefficiencies due
                  to  decreased   production  beginning  December  1997  through
                  February 1998 which resulted in additional  charges to Cost of
                  Sales of  approximately $264,000 during that period, and lower
                  average selling prices for bulk Spirulina.

                           Operating Expenses
                  Operating expenses increased by $379,000, an increase of 12.4%
                  over  the  prior   year,   primarily   because  of   increased
                  expenditures for sales and marketing.

                      Research and  Development.  Expenditures  for research and
                  development  increased  15.3% to $677,000,  for the year ended
                  March 31, 1998,  from  $587,000,  for the year ended March 31,
                  1997. The increase from the prior year is primarily the result
                  of  research  and  ongoing   development   work  done  on  the
                  mosquitocide  project  and  on  optimizing  production  of the
                  natural  astaxanthin  product.  Research and development costs
                  are  expected to  increase  further  during  fiscal 1999 as we
                  continue to optimize the PhytoMax PCS technology, increase the
                  research activities  directed at the mosquitocide  project and
                  begin development work to produce Aldolase  Catalytic Antibody
                  38C2 as a result of our exclusive  license  agreement with The
                  Scripps Research Institute which was signed in April 1998.

                     General  and  Administrative.  General  and  administrative
                  expenses  decreased  8.3% to  $1,318,000,  for the year  ended
                  March 31, 1998, from $1,437,000,  for the year ended March 31,
                  1997.  The decrease  from the prior year is  primarily  due to
                  reduced  associate  incentive bonuses which are indexed to the
                  Company's  profitability,  partially  offset by an increase in
                  personnel costs.

                     Sales and Marketing. Sales and marketing expenses increased
                  39.5% to $1,442,000,  for the year ended March 31, 1998,  from
                  $1,034,000,  for the year ended March 31,  1997.  The increase
                  from the  prior  year is  primarily  due to  higher  personnel
                  costs,  and  increased  domestic and  international  marketing
                  efforts  associated  with  the  introduction  of the  NatuRose
                  product.


                           Other Income (Expense)
                  Other  income  decreased  by 57.1% to  $175,000,  for the year
                  ended March 31, 1998, from $408,000,  for the year ended March
                  31,  1997.  The  decrease  from the  prior  year is  primarily
                  related to  decreased  earnings on lower  balances of cash and
                  investment securities.

                           Income Taxes
                  The  provision  for income  taxes was  $175,000,  for the year
                  ended  March  31,  1998.  This  is due to an  increase  in the
                  allowance  for deferred tax assets,  offset in part by current
                  income tax benefits.

                           Net Income (Loss)
                  For the year ended March 31, 1998 and for the first time since
                  1991,  the  Company  recorded a net loss.  The fiscal 1998 net
                  loss of $300,000,  compares with net income of $4,159,000, for
                  the year ended March 31, 1997.  The net loss is primarily  the
                  result of lower sales of Spirulina bulk and packaged  consumer
                  products due to a reduction  in orders from a single  customer
                  in China that had previously  accounted for a large percentage
                  of sales of packaged  consumer  Spirulina  Pacifica  products,
                  lower  average  selling  prices for bulk  Spirulina  products,
                  Spirulina   production   inefficiencies   due   to   decreased
                  production  during  December 1997 through  February 1998 which
                  resulted  in  an  additional   charge  to  Cost  of  Sales  of
                  approximately $264,000 during the third and fourth quarters of
                  1998, and start-up costs associated with  commercialization of
                  NatuRose, our natural astaxanthin product.
                     In February  1998,  the Company  reduced its  workforce  by
                  approximately  25% in order to  better  align  resources  with
                  sales  levels.  The  workforce   reduction  was  part  of  the
                  Company's  plans to enhance its competitive  position  through
                  improvements of operational  productivity and cost reduction -
                  specifically   more   effecient   utilization  of  assets  and
                  employees.  Production  operations,  sales, and administrative
                  functions were restructured and downsized by this action.


Fiscal 1997 Compared to Fiscal 1996

                           Net Sales
                  Net sales for the year ended March 31, 1997 were  $11,399,000,
                  a 41.1%  increase  over net sales of  $8,081,000  for the year
                  ended March 31,  1996.  The  increase in net sales  during the
                  year ended March 31,  1997 is  attributable  to  significantly
                  higher  production  and  sales of bulk  Spirulina  powder  and
                  tablets  and  increased  sales of packaged  consumer  products
                  which carry a higher sales price than bulk Spirulina  Pacifica
                  products.  The increased production is the result of Spirulina
                  production  expansions  that were  completed  in February  and
                  November 1996.

<PAGE>
                           Gross Profit
                  Gross  profit  increased  to 59.7% of net  sales  for the year
                  ended  March  31,  1997  from  56.5% of net sales for the year
                  ended March 31,  1996.  The  increase in gross profit from the
                  prior year is  primarily  attributable  to  economies of scale
                  related to the  production of both bulk and packaged  consumer
                  Spirulina Pacifica products, but was partially offset by lower
                  average selling prices (18% lower) for bulk products.

                           Operating Expenses
                  Operating expenses  increased by $1,066,000,  with significant
                  increases in all three components.

                     Research and  Development.  Expenditures  for research and
                  development  increased  67.2% to $587,000,  for the year ended
                  March 31, 1997,  from  $351,000,  for the year ended March 31,
                  1996. The increase from the prior year is primarily the result
                  of  the  development  work  done  on the  natural  astaxanthin
                  product  and  the  research  work  done  on  the  mosquitocide
                  project.

                     General  and  Administrative.  General  and  administrative
                  expenses  increased  20.2% to  $1,437,000,  for the year ended
                  March 31, 1997, from $1,196,000,  for the year ended March 31,
                  1996.   The   increase   is   due  to   higher   staff-related
                  expenditures,  the  accrual  of  associate  incentive  bonuses
                  indexed to the Company's  profitability  during the year ended
                  March 31, 1997, and higher insurance costs.

                     Sales and Marketing. Sales and marketing expenses increased
                  132.4% to $1,034,000,  for the year ended March 31, 1997, from
                  $445,000, for the year ended March 31, 1996. The increase from
                  the  prior  year  is  primarily  due to  higher  staff-related
                  expenditures,   and  increased   domestic  and   international
                  marketing  efforts  associated  with higher  sales of packaged
                  consumer  products and with the  introduction  of the NatuRose
                  product.

                           Other Income (Expense)
                  Other income  increased to $408,000,  for the year ended March
                  31, 1997,  from other  expense of $62,000,  for the year ended
                  March 31, 1996.  The increase from the prior year is primarily
                  related to  increased  earnings on larger cash and  investment
                  securities balances.

                           Net Income
                  Net income  increased to $4,159,000,  for the year ended March
                  31, 1997, from $2,509,000,  for the year ended March 31, 1996.
                  The  increase in net income is primarily a result of increased
                  production and sales of bulk and packaged  consumer  Spirulina
                  Pacifica products.
                     Inflation  during  the years ended March 31, 1998, 1997 and
                  1996  did  not  have  a  material  impact  on  the   Company's
                  operations.


Variability of Results

                  Cyanotech  Corporation  was  formed in 1983 and did not become
                  profitable  on an annual  basis until  fiscal 1992 (the twelve
                  month  period  ended  December  31,  1992).  From  fiscal 1992
                  through  fiscal  1997,  the  Company  had  total  net sales of
                  $29,401,000,  and total net  income of  $7,931,000.  In fiscal
                  1998,  the Company had net sales of $7,627,000  and a net loss
                  of $300,000. As of March 31, 1998, our accumulated deficit was
                  $761,000.   There  can  be  no  assurance   that  we  will  be
                  consistently  profitable  on either a  quarterly  or an annual
                  basis. We have experienced quarterly fluctuations in operating
                  results and anticipate that these fluctuations may continue in
                  future periods.  Future  operating  results may fluctuate as a
                  result of changes in sales  levels to our  largest  customers,
                  new product introductions,  production  difficulties,  weather
                  patterns,  the mix between sales of bulk products and packaged
                  consumer   products,   start-up  costs   associated  with  new
                  facilities,  expansion  into new  markets,  sales  promotions,
                  competition,  increased  energy  costs,  the  announcement  or
                  introduction  of new products by our  competitors,  changes in
                  our customer mix,  overall  trends in the market for Spirulina
                  and astaxanthin products and other factors beyond our control.
                  While  a  significant   portion  of  our  expense  levels  are
                  relatively  fixed,  and the  timing of  increases  in  expense
                  levels  is based  in large  part on our  forecasts  of  future
                  sales,  if net  sales  are  below  expectations  in any  given
                  period,  the adverse  impact on results of  operations  may be
                  magnified by our inability to adjust  spending  quickly enough
                  to compensate for the sales  shortfall.  We may also choose to
                  reduce  prices or  increase  spending  in  response  to market
                  conditions,  which may have a material  adverse  effect on our
                  results of operations.

New Accounting Standards

                  In  June  1996,  the  Financial   Accounting  Standards  Board
                  ("FASB") issued  Statement of Financial  Accounting  Standards
                  ("SFAS") No. 125,  "Accounting  for Transfers and Servicing of
                  Financial Assets and Extinguishments of Liabilities". SFAS No.
                  125  generally is effective  for  transfers  and  servicing of
                  financial assets and extinguishments of liabilities  occurring
                  after December 31, 1996,  and is to be applied  prospectively.
                  This Statement provides accounting and reporting standards for
                  transfers    and    servicing   of   financial    assets   and
                  extinguishments of liabilities based on consistent application
                  of a financial-components approach that focuses on control. It
                  distinguishes  transfers  of  financial  assets that are sales
                  from  transfers  that are secured  borrowings.The  adoption of
                  SFAS No. 125 did not have a material  effect on the  Company's
                  reported   financial   position,   results  of  operations  or
                  liquidity.
                     In February 1997,  the FASB issued SFAS No. 128,  "Earnings
                  per Share".  SFAS No. 128 is  effective  for both  interim and
                  annual periods  ending after  December 15, 1997.  SFAS No. 128
                  requires  the  presentation  of  "Basic"  earnings  per share,
                  representing income available to common  shareholders  divided
                  by the weighted  average  number of common shares  outstanding
                  during the period,  and  "Diluted"  earnings per share,  which
                  reflects the potential dilution that could occur if securities
                  or other contracts to issue Common Stock shares were exercised
                  or  converted  into  Common  Stock  shares or  resulted in the
                  issuance  of  Common  Stock  shares  that  then  shared in the
                  earnings of the Company.  SFAS No. 128 requires restatement of
                  all prior period per share data presented. The Company adopted
                  SFAS No. 128 for the quarter  ended  December 31, 1997 and has
                  restated all prior period earnings per share data presented.
                     Also during  February  1997,  the FASB issued SFAS No. 129,
                  "Disclosure of  Information  about Capital  Structure,"  which
                  lists required  disclosures  about capital  structure that had
                  been  included in a number of previously  existing  statements
                  and  opinions.  SFAS No. 129 is effective  for periods  ending
                  after December 15, 1997. The Company adopted the provisions of
                  SFAS No. 129 as of December 31, 1997. The adoption of SFAS No.
                  129 did not have a material  effect on the Company's  reported
                  financial information.
                     In June 1997,  the FASB  issued  SFAS No.  130,  "Reporting
                  Comprehensive  Income,"  which  establishes  standards for the
                  reporting  and  display  of   comprehensive   income  and  its
                  components  in  a  full  set  of   general-purpose   financial
                  statements.  SFAS  No.  130  is  effective  for  fiscal  years
                  beginning  after  December  15,  1997.  SFAS No. 130  requires
                  reclassification  of financial  statements for earlier periods
                  provided for comparative purposes.  The Company will adopt the
                  provisions of SFAS No. 130 for the fiscal year beginning April
                  1, 1998.
                     Also  during  June  1997,  the FASB  issued  SFAS No.  131,
                  "Disclosures  about  Segments  of an  Enterprise  and  Related
                  Information," which establishes  standards for public business
                  enterprises to report  information about operating segments in
                  annual   financial   statements   and   requires   that  those
                  enterprises   report  selected   information  about  operating
                  segments in interim  financial reports issued to shareholders.
                  SFAS No. 131 is  effective  for fiscal years  beginning  after
                  December  15,  1997.  SFAS No.  131  requires  restatement  of
                  comparative  information  presented for earlier  periods.  The
                  Company  will  adopt the  provisions  of SFAS No.  131 for the
                  quarter  beginning  April 1, 1998.  Management does not expect
                  adoption  of SFAS No. 131 will have a  material  effect on the
                  Company's reported financial information.
                     In February 1998, the FASB issued SFAS No. 132, "Employers'
                  Disclosures about Pensions and Other Postretirement Benefits,"
                  which  amends  the  disclosure  requirements  of SFAS No.  87,
                  "Employers' Accounting for Pensions," SFAS No. 88, "Employers'
                  Accounting for Settlements and Curtailments of Defined Benefit
                  Pension Plans and for Termination  Benefits" and SFAS No. 106,
                  "Employers' Accounting for Postretirement  Benefits Other Than
                  Pensions." SFAS No. 132 addresses disclosure only and does not
                  change  any  of  the  measurement  or  recognition  provisions
                  provided  for in SFAS  Nos.  87,  88 or 106.  SFAS No.  132 is
                  effective for fiscal years  beginning  after December 15, 1997
                  and requires restatement of comparative  information presented
                  for earlier periods.  The Company will adopt the provisions of
                  SFAS No.  132 for the  fiscal  year  beginning  April 1, 1998.
                  Management  does not expect adoption of SFAS No. 132 will have
                  a  material  effect  on  the  Company's   reported   financial
                  information.
                     In March 1998, the American  Institute of Certified  Public
                  Accountants ("AICPA") Accounting Standards Executive Committee
                  issued Statement of Position ("SOP") 98-1, "Accounting for the
                  Costs of Computer Software  Developed or Obtained for Internal
                  Use," which  requires that certain  costs,  including  certain
                  payroll  and   payroll-related   costs,   be  capitalized  and
                  amortized over the estimated useful life of the software.  The
                  provisions   of  SOP  98-1  are  effective  for  fiscal  years
                  beginning  after  December  15,  1998.  The  Company  has  not
                  determined when it will adopt SOP 98-1.  Management  estimates
                  that the adoption of SOP 98-1 will not have a material  effect
                  on the Company's financial condition, results of operations or
                  liquidity.

                     In April 1998,  the AICPA  Accounting  Standards  Executive
                  Committee issued SOP 98-5, "Reporting on the Costs of Start-up
                  Activities."   SOP  98-5   requires  that  costs  of  start-up
                  activities,  including  organization  costs,  be  expensed  as
                  incurred.  The provisions of SOP 98-5 are effective for fiscal
                  years   beginning   after   December   15,  1998  and  earlier
                  application is encouraged. The Company has not determined when
                  it will adopt SOP 98-5. Management does not expect adoption of
                  SOP  98-5  will  have  a  material  effect  on  the  Company's
                  financial condition, results of operations or liquidity.

Liquidity and Capital Resources

                  Cyanotech's   cash   and   investment   securities   decreased
                  $5,332,000  to  $1,397,000  during the fiscal year ended March
                  31, 1998. The decrease is primarily  attributable to increased
                  capital expenditures for equipment and leasehold improvements.
                     Cash flows provided by operating  activities  were $988,000
                  in 1998, down from $2,860,000 in 1997 because of the reduction
                  in net  income.  The  primary  sources of 1998 cash flows from
                  operating   activities   were  a  decrease  in  net   accounts
                  receivable, offset in large part by an increase in inventories
                  and decreases in accounts payable and accrued expenses.
                     Cash flows used in investing  activities were $1,927,000 in
                  1998 compared to $10,962,000 in 1997. The primary uses of cash
                  flows in  investing  activities  during  1998 were for capital
                  expenditures totaling $5,881,000,  offset by proceeds from the
                  sale  and   maturities  of  investment   securities   totaling
                  $3,954,000.
                     Cash flows used in financing  activities  were  $439,000 in
                  1998 compared to cash flow provided by financing activities of
                  $1,468,000  in  1997.  The  primary  uses  of  cash  flows  in
                  financing  activities were for principal  payments of $401,000
                  on long-term  debt and $130,000 on capital lease  obligations,
                  offset  somewhat by  proceeds  received  from the  exercise of
                  common stock options and warrants.
                     As of March 31, 1998,  we had no  significant  construction
                  commitments.  However,  we  have  agreed  with a  construction
                  contractor to resume work on a culture pond expansion  project
                  by January 1, 1999 in a  reasonable  and  customary  manner in
                  accordance  with the  terms of the  contract  and at a minimum
                  billable rate of $150,000 per month. The remaining  balance on
                  the construction  contract is approximately  $1.9 million.  If
                  work does not  resume by  January 1,  1999,  and  continue  as
                  agreed  because  of  the  Company's  inability  to  fund  such
                  construction, then the contract may be considered to have been
                  terminated  by Cyanotech.  Assertion by the  contractor of its
                  termination rights could have a material adverse effect on the
                  Company's  financial  condition,   results  of  operations  or
                  liquidity.  Total  costs  incurred  as of March 31,  1998 with
                  respect  to this  expansion  project  approximate  $2,643,000.
                  Management  expects to resume work on the project on or before
                  January 1, 1999.
                     We presently  estimate that our existing capital  resources
                  and  anticipated  cash flows from  future  operations  will be
                  sufficient  to fund current  operations.  However,  we plan to
                  spend,  subject  to  available  financing,  approximately  $11
                  million on capital  expenditures  during the next three fiscal
                  years,   primarily  to  continue  the  expansion  of  NatuRose
                  production  on the newly  leased 93  acres.  Existing  capital
                  resources and  anticipated  cash flows from future  operations
                  will not be sufficient to fund these capital expenditures. Our
                  bank credit line of $1,000,000 expired on January 31, 1998 and
                  was not  renewed.  Another  $1,000,000  bank line  expired  on
                  February 7, 1998 when the  underlying  certificate  of deposit
                  matured.  As of March  31,  1998,  the  Company  was  actively
                  pursuing  additional credit facilities to meet any anticipated
                  shortfall in cash flow,  but there is no  assurance  that such
                  facilities  will  be  obtained  at the  amount  required  at a
                  reasonable cost to the Company.


Year 2000 Compliance

                  The  Company  has  completed  a  comprehensive  review  of its
                  computer  systems  to  identify  the  systems  that  could  be
                  affected  by the  "Year  2000"  issue  and  has  developed  an
                  implementation  plan,  to be  completed  by the end of  fiscal
                  1999,  to  resolve  the  issue.  The Year 2000  problem is the
                  result of computer  programs  being  written  using two digits
                  rather  than four to define the  applicable  year.  Any of the
                  Company's  programs  that  have  time-sensitive  software  may
                  recognize  a date using "00" as the year 1900  rather than the
                  year 2000.  This  could  result in a major  system  failure or
                  miscalculations. The Company believes that, with modifications
                  to existing software and converting to new software,  the Year
                  2000 problem will not pose  significant  operational  problems
                  for  the  Company's   computer  systems  as  so  modified  and
                  converted. The costs of such modifications and conversions are
                  not expected to be material.  However,  if such  modifications
                  and conversions are not completed in a timely manner, the Year
                  2000 problem may have a material  impact on the  operations of
                  the Company.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



          (all amounts in thousands, except share data)

Note 1    Description of Business and Summary of Accounting Policies

                    a. Description of Business
          Cyanotech  Corporation  (Company) develops and  commercializes natural
          products from microalgae.The Company is currently producing microalgae
          products for the nutritional supplement, aquaculture feed/pigments and
          immunological diagnostics  markets  and is also developing microalgae-
          based  products  for  the  biopesticide,  chiral  chemistry  and  food
          coloring markets.
               Substantially   all   of   the  Company's  net  sales  have  been
          attributable  to  its   Spirulina  Pacifica(TM)  products.   Sales  of
          Spirulina Pacifica   products accounted for  approximately  95% of the
          Company's net sales for the year  ended  March 31, 1998  and  98%  for
          the  years ended March 31, 1997 and 1996.

                    b. Principles of Consolidation
          The Company consolidates enterprises  in  which  it  has a controlling
          financial interest. The accompanying consolidated financial statements
          include  the  accounts  of  Cyanotech  Corporation,  its  wholly owned
          subsidiaries,  Nutrex, Inc. and Cyanotech International FSC, Inc.  All
          significant  intercompany   balances   and   transactions  have   been
          eliminated in consolidation.
               Cyanotech  International  FSC, Inc., was formed on  April 1, 1997
          as a foreign sales corporation under the Internal Revenue Code.

                    c. Cash and Cash Equivalents
          For purposes of the consolidated statements of cash flows, the Company
          considers all highly liquid debt securities purchased with original or
          remaining  maturities of three months or less to be cash equivalents.

                    d. Investment Securities
          Investment  securities at March 31,  1997  consisted  of U.S.Treasury,
          mortgage-backed, and other interest bearing securities.   The  Company
          classifies its debt and equity securities in one of three  categories;
          trading, available-for-sale, or  held-to-maturity.  Trading securities
          are bought  and held  principally  for the  purpose of selling them in
          the near term.  Held-to-maturity  securities are  those  securities in
          which  the  Company   has  the  ability   and   intent  to   hold  the
          security until maturity.  All other securities not included in trading
          or held-to-maturity are classified as available-for-sale.
               Trading and available-for-sale securities  are  recorded  at fair
          value.   Held-to-maturity securities are  recorded  at amortized cost,
          adjusted  for  the amortization or accretion of premiums or discounts.
          Unrealized holding gains and losses on trading securities are included
          in earnings.   Unrealized holding gains and losses, net of the related
          tax  effects,  on  available-for-sale  securities  are  excluded  from
          earnings  and  are  reported as a separate  component of stockholders'
          equity  until  realized.  Realized  gains  and losses from the sale of
          held-to-maturity and available-for-sale securities are determined on a
          specific identification basis.
               A decline in the market value of any  available-for-sale or held-
          to-maturity  security  below  cost  that  is  deemed  to be other than
          temporary results in a reduction in carrying amount to fair value. The
          impairment  is  charged  to  earnings  and  a  new  cost basis for the
          security is  established.  Premiums  and discounts  are  amortized  or
          accreted over the life of the related held-to-maturity  security as an
          adjustment to yield using the effective interest method.  Dividend and
          interest income are recognized when earned.

                    e. Inventories
          Inventories  are stated at the lower of cost which approximates first-
          in, first-out)  or  market.   Market  is  determined by net realizable
          value.

                    f. Equipment and Leasehold Improvements
          Owned  equipment  and  leasehold  improvements  are  stated  at  cost.
          Equipment  under  capital  lease is stated at the lower of the present
          value of minimum lease payments or fair value of the equipment  at the
          inception of the lease.  Depreciation  and  amortization  are provided
          using the straight-line  method over  the  estimated  useful lives for
          equipment  and furniture and fixtures  and the  shorter  of the  lease
          terms  or  estimated  useful  lives  for  leasehold  improvements  and
          equipment under capital lease as follows:

                                       13
<PAGE>
          Equipment                                                3 to 10 years
          Leasehold improvements           remaining lease term (10 to 28 years)
          Furniture and fixtures                                         7 years
          Equipment under capital lease                lease term (3 to 5 years)

          Amortization   of  equipment  under  capital  lease  is   included  in
          depreciation and amortization expense in the accompanying consolidated
          financial statements.
          
               g. Earnings Per Share
          In February 1997,  the  Financial Accounting Standards  Board ("FASB")
          issued  Statement of Financial Accounting  Standards ("SFAS") No. 128,
          Earnings per Share.  SFAS No. 128  is effective  for both  interim and
          annual periods  ending after December 15, 1997.  SFAS No. 128 requires
          the  presentation of "Basic" earnings per share,  representing  income
          available to  common  shareholders  divided  by  the  weighted average
          number of common shares outstanding  for  the  period,  and  "Diluted"
          earnings  per  share, which reflects the potential dilution that could
          occur  if  securities  or other contracts to issue Common Stock shares
          were  exercised or  converted  into Common Stock shares or resulted in
          the issuance of Common Stock shares that then  shared in the  earnings
          of the Company.  SFAS No. 128 requires restatement of all prior period
          earnings per share data  presented.  The Company adopted SFAS No.  128
          for the quarter  ended  December  31, 1997 and has  restated all prior
          period earnings per share data presented.
               For  the  year  ended  March 31, 1998,  warrants  and  options to
          purchase Common Stock shares of the Company and  convertible preferred
          stock were outstanding,  but were not included in the 1998 computation
          of Diluted net loss per common share because the  inclusion  of  these
          securities would have had  an antidilutive  effect on the net loss per
          common  share.  As of March 31, 1998,  warrants  and options to aquire
          431,725  shares  of  the  Company's  common  stock and preferred stock
          convertible into 2,975,155 shares of the Company's common  stock  were
          outstanding.
               Following is a reconciliation of the numerators  and denominators
          of  the  Basic  and  Diluted  net  income  (loss)  per  Common   Share
          computations  for  the  periods  presented  (in thousands except share
          data):

          1996 respectively.

                    i. Income Taxes
          Deferred tax assets and liabilities are recognized  for the future tax
          consequences   attributable  to  differences   between  the  financial
          statement  carrying  amounts of existing assets  and  liabilities  and
          their  tax  bases  and  operating  

                                       14
<PAGE>

          loss carryforwards.  Deferred tax assets and liabilities  are measured
          using  enacted  income tax rates applicable  to the  period  in  which
          the   deferred   tax assets or liabilities are expected to be realized
          or settled.  As changes in tax laws or rates are enacted, deferred tax
          assets and  liabilities  are adjusted through the provision for income
          taxes.

                    j. Stock Option Plan
          Prior to April 1, 1996,  the  Company  accounted  for its stock option
          plan in accordance with the  provisions of Accounting Principles Board
          ("APB") Opinion No. 25, Accounting for Stock Issued to Employees,  and
          related  interpretations.  As such,  compensation expense was recorded
          on  the  date  of  grant  only if  the  current  market  price for the
          underlying stock exceeded the exercise price. Effective April 1, 1996,
          the   Company   adopted   SFAS  No. 123,  Accounting  for  Stock-Based
          Compensation, which permits  entities  to  recognize  as expense  over
          the  vesting  period  the fair  value of all stock-based awards on the
          date of grant.
               Alternatively,  SFAS No. 123  also allows entities to continue to
          apply  the provisions of APB Opinion No. 25 and  provide pro forma net
          income and pro forma net  income  per  common  share  disclosures  for
          employee stock option grants made in fiscal year 1996 and future years
          as if the  fair-value-based  method  defined in SFAS No. 123 had  been
          applied.  The Company has elected to continue to apply the measurement
          provisions  of  APB  No.  25  and  provide  the  pro forma disclosures
          required by SFAS No. 123.

                    k. Impairment  of  Long-Lived  Assets  and Long-Lived Assets
          to Be Disposed Of
          The Company adopted the provisions of SFAS No. 121, Accounting for the
          Impairment  of  Long-Lived  Assets  and  for  Long-Lived Assets  to Be
          Disposed Of, effective April 1, 1996. SFAS No. 121 requires that long-
          lived  assets  and certain  identifiable intangibles  be reviewed  for
          impairment whenever  events or changes in circumstances  indicate that
          the carrying amount of an asset may not be recoverable. Recoverability
          of  assets  to  be held  and used is measured by a  comparison  of the
          carrying amount of an asset to future net cash  flows  expected  to be
          generated by the asset.  If such assets are considered to be impaired,
          the impairment to be recognized is measured as the amount the carrying
          amount of the assets exceeds  the fair value of the assets.  Assets to
          be  disposed  of  are  reported at the lower of the carrying amount or
          fair value less costs to sell.  Adoption  of SFAS No. 121 did not have
          a material  impact  on  the  Company's financial position,  results of
          operations or liquidity.

                    l.  Transfers  and   Servicing   of   Financial  Assets  and
          Extinguishments of Liabilities
          In June 1996, the FASB issued SFAS No. 125,  Accounting  for Transfers
          and Servicing of Financial Assets and Extinguishments of  Liabilities.
          SFAS No. 125  generally  is  effective  for transfers and servicing of
          financial  assets and extinguishments of liabilities  occurring  after
          December 31, 1996 and is to be applied prospectively.  This  Statement
          provides   accounting   and  reporting  standards  for  transfers  and
          servicing of financial assets and extinguishments of liabilities based
          on  consistent  application  of  a  financial-components approach that
          focuses on  control.  It distinguishes transfers of  financial  assets
          that are sales  from transfers that are secured  borrowings.  Adoption
          of SFAS No.  125 did  not  have a  material  impact  on the  Company's
          financial position, results of operations or liquidity.

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

                    n. New Accounting Pronouncements 
          In  February  1997,  the  FASB  issued  SFAS  No. 129,  Disclosure  of
          Information about Capital Structure,  which lists required disclosures
          about  capital  structure  that  had  been  included  in  a  number of
          previously existing statements and opinions. SFAS No. 129 is effective
          for periods ending after  December 15, 1997.  The Company  adopted the
          provisions  of  SFAS No. 129 as of December 31, 1997.  The adoption of
          SFAS No. 129 did not have  a material effect on the Company's reported
          financial information. 
               In   June  1997,   the   FASB  issued  SFAS  No.  130,  Reporting
          Comprehensive Income, which establishes standards  for  the  reporting
          and display of comprehensive  income  and its components in a full set
          of general-purpose financial statements. SFAS No. 130 is effective for
          fiscal years beginning after December 15, 1997.  SFAS No. 130 requires
          reclassification of financial  statements for earlier periods provided
          for  comparative  purposes.  The  Company will adopt the provisions of
          SFAS  No.  130  for  the  fiscal  year  beginning  April  1, 1998.  
               In June 1997,  the  FASB also issued SFAS  No.  131,  Disclosures
          about  Segments  of  an  Enterprise  and  Related  Information,  which
          establishes  standards  for  public  business  enterprises  to  report
          information  about 

                                       15
<PAGE>

          operating  segments in annual financial statements and  requires  that
          those enterprises report selected information about operating segments
          in  interim  financial reports  issued  to shareholders.  SFAS No. 131
          is  effective  for fiscal years  beginning  after  December  15, 1997.
          SFAS No. 131 requires restatement of comparative information presented
          for  earlier  periods.  The Company will adopt the provisions of  SFAS
          No. 131 for the quarter beginning April 1, 1998.  Management does  not
          expect adoption of SFAS No. 131 will have  a  material  effect  on the
          Company's  reported  financial information.  
               In February 1998,  the  FASB  issued   SFAS  No.  132, Employers'
          Disclosures about Pensions and  Other  Postretirement Benefits,  which
          amends  the  disclosure  requirements  of  SFAS  No.  87,   Employers'
          Accounting  for  Pensions,  SFAS  No.  88,  Employers'  Accounting for
          Settlements and Curtailments of Defined Benefit Pension  Plans and for
          Termination  Benefits  and  SFAS  No. 106,  Employers'  Accounting for
          Postretirement  Benefits  Other Than Pensions.  SFAS No. 132 addresses
          disclosure  only  and  does  not  change  any  of  the  measurement or
          recognition provisions provided for in SFAS Nos. 87, 88 or 106.   SFAS
          No. 132 is effective for fiscal  years  beginning   after December 15,
          1997 and requires restatement of comparative information presented for
          earlier periods. The Company will adopt the provisions of SFAS No. 132
          for  the  fiscal  year  beginning  April 1, 1998.  Management does not
          expect  adoption  of  SFAS No. 132 will have a material  effect on the
          Company's  reported  financial information.   
               In  March  1998,  the  American  Institute  of  Certified  Public
          Accountants  ("AICPA") Accounting Standards Executive Committee issued
          Statement of  Position  ("SOP")  98-1,  Accounting  for the  Costs  of
          Computer  Software  Developed  or  Obtained for  Internal  Use,  which
          requires that certain costs, including certain  payroll  and  payroll-
          related costs, be capitalized  and amortized over the estimated useful
          life of the software.  The provisions of SOP 98-1  are  effective  for
          fiscal years  beginning after  December 15, 1998.  The Company has not
          determined when it will adopt SOP 98-1.  Management estimates that the
          adoption of SOP 98-1 will not have a material effect on the  Company's
          financial  condition,  results of operations or  liquidity.  
               In April 1998, the AICPA Accounting Standards Executive Committee
          issued SOP 98-5,  Reporting  on  the  Costs  of  Start-up  Activities.
          SOP  98-5  requires  that  costs  of  start-up activities,   including
          organization costs, be  expensed  as  incurred.  The provisions of SOP
          98-5 are effective for fiscal years beginning  after December 15, 1998
          and earlier application is encouraged.  The Company has not determined
          when it will adopt SOP 98-5.  Management does not expect  adoption  of
          SOP 98-5  will  have  a  material  effect  on the Company's  financial
          condition,  results of operations or liquidity.

          On  April  1,  1995,  the  Company  executed  a  $250 note, payable in
          principal  installments  of  $12.5 each quarter through April 1, 2000,

          delivering  to the lender an equivalent market value amount of salable
          product  or  cash (at the  lender's option).  The note  payable  bears
          interest at  LIBOR plus 2%,  adjusted  quarterly,  and is  secured  by
          certain  production  equipment.  For the quarter ended March 31, 1998,
          interest on this note was calculated at 7.97%.
               On  July 11, 1995,  the  Company executed a $500 note, payable in
          principal  installments of $25 each quarter through July 1, 2000, plus
          interest, with principal and interest payments satisfied by delivering
          to the lender an equivalent market value amount of salable product  or
          cash (at the lender's option). The note payable bore interest at LIBOR
          plus 2%, adjusted quarterly,  and was  secured  by  certain  leasehold
          improvements.  This note was satisfied, in its entirety, in 1998.

                    Note payable
          In March  1998,  the  Company  reached an  agreement  with its general
          contractor  to  convert  certain  trade  accounts  payable  to  a note
          payable.  Under  the  terms  of the agreement,  $975 of trade accounts
          payable to the contractor for work completed on an  expansion  project
          was converted  to a note  payable due December 31, 1998.  Terms of the
          note  call  for  a  principal and interest payment of $150 on April 1,
          1998,  monthly  principal  and  interest  payments  of  $100 beginning
          June 1, 1998,  and the  balance due on  December  31,  1998.  The note
          payable  bears interest at prime plus 2%,  beginning  January 1, 1998,
          and is  secured by all of the assets of the  Company.  As of March 31,
          1998, the interest rate was calculated at 10.5%.

          equipment and  land under operating leases expiring  between  1999 and
          2025.  The Company has agreed in principle to the lease of  additional

Note 7    Series C Preferred Stock
          Series C preferred stock is convertible  into common stock at the rate
          of  one  share  of  preferred  stock  for five  shares of common stock
          through February 23, 2000,  after which date the conversion feature is
          no  longer applicable.  Series  C preferred stock  has  voting  rights
          equal  to  the  number  of  shares  of  common  stock into which it is
          convertible and has a preference in liquidation  over all other series
          of  preferred  stock of $5  per  share plus any accumulated but unpaid
          dividends.  Holders of Series C  preferred  stock are  entitled  to 8%
          cumulative annual dividends at the rate of $.40 per share;  cumulative
          dividends  in  arrears as of March 31,  1998  amount to $2,061 ($3.463
          per share).  Upon  conversion  of Series C preferred stock, cumulative
          dividends  in  arrears on converted shares are no longer payable.  The
          amount of cumulative dividends foregone due to  conversion  during the
          year ended March 31, 1998 was $457 (nil in 1997 and 1996). The consent
          of Series C preferred stockholders is required to modify their present
          rights or sell all or substantially all of the Company's assets.


Note 8    Stock Options and Warrants

               Stock options
          At   the   Company's   annual   meeting   held   on   August  9, 1995,
          the  stockholders  of  the  Company  approved the Company's 1995 Stock
          Option  Plan (the "1995  Plan"),  reserving a total of 400,000  shares
          of common stock for issuance  under the Plan.  At the Company's annual
          meeting  held on September  17,  1997,  the stockholders  approved  an
          amendment  to  the  1995  Plan  which  increased  the number of shares
          reserved for issuance under the Plan from 400,000 to 800,000. The 1995
          Plan  provides for the issuance of both  incentive  and  non-qualified
          stock options.  Options  are to be granted at or above the fair market
          value of the Company's common stock at the date of grant and generally
          become exercisable over a five-year period.
               The  Company also has a  Non-employee  Director Stock Option  and
          Stock  Grant  Plan,  which was approved by  stockholders  in 1994 (the
          "1994 Plan").  Under the 1994 Plan, and upon election  to the Board of
          Directors,  non-employee  directors  are granted a ten-year  option to
          purchase 3,000 shares of the Company's common stock at its fair market
          value on the date of grant.  In  addition,  on the date of each Annual
          Meeting of  Stockholders in  each  year  that  the  1994  Plan  is  in
          effect,  each non-employee   director   continuing   in   office  will
          be  automatically  granted,  without  payment,  2,000 shares of common
          stock that is  non-transferable  for six months  following the date of
          grant.  Grants of 8,000,  6,000 and 8,000  shares of common stock were
          made under the 1994 Plan in  September  1997 and 1996 and August 1995,
          respectively.  Expense  recognized as  a result of these stock  grants
          amounted to $47,  $37 and $40 for  the  years ended  March  31,  1998,
          1997  and  1996, respectively.

               In 1985,  the  Company  adopted  an  Incentive  Stock Option Plan
          (qualified stock option plan) and authorized 200,000 shares of  common
          stock to be set aside for grants to  officers and key employees of the
          Company.   In 1993,  the stockholders  approved an  amendment  to  the
          Incentive   Stock  Option  Plan  which increased  the number of shares
          reserved  for  issuance  under  this  plan  from  200,000  to 400,000.
          Options  were  granted  with  exercise  prices not lower than the fair
          market  value  of the  Company's  common  stock  at the date of grant.
          Options    generally   became   exercisable  in   four   equal  annual
          installments,  commencing  one year from the date of grant and expire,
          if not exercised, five years from the date of grant, unless stipulated
          otherwise by the Compensation and Stock Option Committee of the  Board
          of Directors.  The Incentive Stock Option Plan terminated on March 18,
          1995.  Options  granted  prior  to  the  plan termination date are not
          affected.
               At March 31, 1998, there were 466,500 additional shares available
          for grant under the 1995 Plan and 63,000  additional shares  available
          under  the  1994  Plan.   The  per  share weighted-average  fair value
          of stock options  granted  during 1998, 1997 and 1996 was $6.31, $6.02
          and $3.90, respectively, on the date of  grant  using a Black  Scholes
          option-pricing model with the following weighted-average  assumptions:
          1998 - expected dividend yield of 0%, risk-free interest rate of 6.6%,
          expected  volatility  of 99%,  and an expected life of 4.5 years; 1997
          expected  dividend  yield  of  0%,  risk-free  interest  rate of 6.6%,
          expected volatility of 130%, and an expected life of 4.1 years; 1996 -
          expected  dividend  yield  of  0%,  risk-free interest  rate  of 6.2%,
          expected volatility of 110%, and an expected life of 4.3 years.
               The Company applies APB Opinion No. 25 in accounting for employee
          stock-based compensation and,  accordingly,  no  compensation cost has
          been  recognized for its employee stock  options  in the  accompanying
          financial  statements.  Had the Company determined  compensation  cost
          based on the estimated  fair value at the grant date for its  employee
          stock options under SFAS No. 123, the Company's net income  (loss) and
          net income (loss) per common share would have been as reflected in the
          pro forma amounts below:

</TABLE>
          Pro forma  net income  (loss) and net income  (loss) per common  share
          information reflect only options  granted  since 1996. Therefore,  the
          full impact of calculating compensation cost for stock  options  under
          SFAS No. 123  is  not reflected in the pro forma net income (loss) and
          net  income (loss)  per common share amounts  presented  above because
          compensation  cost is reflected  over the options'  vesting  period of
          5 years, and compensation  cost for options  granted prior to April 1,
          1995 is not considered.

</TABLE>

          The  valuation  allowance for deferred tax assets as of April 1, 1997,
          1996  and  1995  was  $134,  $1,675  and  $2,751,  respectively.   The
          valuation allowance increased by $270  during the year ended March 31,
          1998  and  decreased  by  $1,541  and  $1,076  during  the years ended
          March 31, 1997 and 1996, respectively.  In assessing the realizability
          of deferred tax assets, management considers whether it is more likely
          than not that some portion or all of the deferred  tax assets will not
          be  realized.  The  ultimate  realization  of  deferred  tax assets is
          dependent  upon  the  generation  of  future taxable income during the
          periods in which those  temporary   differences   become   deductible.
          Management   considers   the   scheduled   reversal  of  deferred  tax
          liabilities,  projected  future  taxable  income,   and  tax  planning
          strategies in making this assessment.
               Based upon the level of historical taxable income and projections
          for future taxable income over the periods which the net deferred  tax
          assets are deductible,  management believes it is more likely than not
          the   Company   will   realize   the   benefits  of  these  deductible
          differences,  net  of  the  existing  valuation allowance at March 31,
          1998.  The  amount  of  the deferred tax asset considered  realizable,
          however, could  be  reduced  in the near term if  estimates  of future
          taxable income during the carryforward period are reduced.
               At March 31, 1998, the Company has  tax net  operating  tax  loss
          carryforwards  available  to offset  future  federal and state taxable
          income and tax credit carryforwards available to offset future federal
          income taxes as follows:

Note 12   Fair Value of Financial Instruments

          SFAS Statement No.  107,  "Disclosures  about  Fair Value of Financial
          Instruments," defines the fair value of a financial instrument  as the
          amount  at  which  the  instrument  could  be  exchanged  in a current
          transaction between willing parties.
               The  following  methods and assumptions were used to estimate the
          fair value of each class of financial instruments as of March 31, 1998
          and 1997:

                    Cash and Cash Equivalents
          The carrying amounts approximate fair value  because of the short-term
          nature of these instruments.

                    Investment Securities
          The fair  value of  investment  securities  is based on quoted  market
          prices  at  the  reporting  date.  The  carrying  value  of investment
          securities approximates fair value.

                    Note Payable
          The carrying value of the note payable approximates fair value as  the
          interest rate of the note approximates the  rate currently  offered to
          the Company for similar debt instruments of a comparable maturity.

                    Long-Term Debt
          The carrying amounts approximate fair  value  because  the instruments
          reprice at market rates on a quarterly basis.


Note 13   Profit Sharing Plan

          The  Company sponsors a 401(k) profit sharing  plan for all associates
          not  covered  under  a  separate management incentive plan.  Under the
          401(k) profit sharing plan, 5% of pre-tax profits are allocated  based
          on gross wages to  non-management associates  on  a  quarterly  basis.
          Fifty percent of each associate's  profit sharing bonus is distributed
          in cash on an after-tax basis, with  the remainder deposited  in  each
          associate's  401(k) account on a pre-tax basis with a six year vesting
          schedule, based on years of service with the Company.  All  associates
          may make voluntary  pre-tax  contributions  to  their 401(k) accounts.
          Compensation  expense relative to this plan  amounted to nil, $219 and
          $132 for the years ended March 31, 1998, 1997 and 1996, respectively.


Note 14   Commitments and Contingencies

          As of March 31, 1998,  the  Company  has  agreed  with  a construction
          contractor  to  resume  work  on  an  expansion  project  on or before
          January 1, 1999 in a  reasonable  and  customary manner in  accordance
          with the terms of the contract and at a  minimum billable rate of $150
          per  month.  The  remaining  balance  on  the construction contract is
          approximately $1.9 million.  If  work  does not  resume  on or  before
          January  1,  1999,  the contract  will  be  considered  to  have  been
          terminated  by  Cyanotech  and  each party will retain all rights with
          respect to  the   termination  of  the  contract.   Assertion  by  the
          contractor  of its  termination  rights  could have a material adverse
          effect on the Company's financial  condition, results of operations or
          liquidity.  Total costs  incurred as of March 31, 1998 with respect to
          this  expansion  project  approximate  $2,643.  Management  expects to
          resume work on the project on or before January 1, 1999.
               The Company is involved in various claims arising in the ordinary
          course  of  business.  In  the  opinion  of  management,  the ultimate
          disposition of these matters will not have a material  adverse  effect
          on   the   Company's   consolidated  financial  position,  results  of
          operations or liquidity.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors Cyanotech Corporation:

          We  have  audited  the  accompanying  consolidated  balance  sheets of
          Cyanotech Corporation and subsidiaries as of March 31, 1998 and  1997,
          and the related consolidated statements  of operations,  stockholders'
          equity  and cash flows for each of  the years in the three-year period
          ended March 31, 1998.  These consolidated financial statements are the
          responsibility of  the Company's management.  Our responsibility is to
          express an opinion on these consolidated 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 consolidated financial  statements referred
          to above present  fairly,  in all material  respects,  the   financial
          position of Cyanotech  Corporation   and  subsidiaries as of March 31,
          1998  and  1997,  and  the  results of their operations and their cash
          flows  for each of the years in the three-year  period ended March 31,
          1998 in conformity with generally accepted accounting principles.
