Item 1.   Description of Business

Introduction

         The  Company,  a  California  corporation,  was founded in 1989 as EROX
Corporation to develop and market a broad range of consumer products  containing
human  pheromones  as a component.  On May 29,  1998,  the  shareholders  of the
Company voted to change the name of the Company to Human Pheromone Science, Inc.
The  Company  believes  that  human  pheromone  research  funded by the  Company
presents  an  opportunity  to create  and market an  entirely  new  category  of
pheromone-based  fragrances  and  toiletry  products,  as well as other types of
consumer  products.  The Company  believes that its related patents provide it a
proprietary  position in  developing,  licensing and marketing a new category of
consumer products that could significantly change the consumer accepted standard
for  products  containing  a  fragrance  component  and for  cosmetic  treatment
products.

         Pheromones are chemical substances known to stimulate  species-specific
biological responses in animals. For ten years,  scientists and advisors engaged
by Human  Pheromone  Science,  Inc.  ("HPSI")  have  studied the  functions  and
characteristics of human pheromones.

         The human  pheromones  included as a component of and as a fixative for
the  Company's  fragrance  products  have been  manufactured  for the Company by
Pherin  Pharmaceuticals,  Inc.. The  manufacturing  process for human pheromones
begins with  hydrocarbon  compounds  commonly  available  from  chemical  supply
houses, and involves the use of a synthetic  chemistry process performed for the
Company by Pherin at its laboratories in Salt Lake City, Utah. In early 1999, in
response to the need for  significant  increases in production,  two independent
laboratories  were engaged to manufacture such pheromones under the direction of
Pherin  scientists.  All the steps in the  manufacturing  process  are  standard
chemical  laboratory  procedures.  The  manufacturing  process for pheromones is
similar to methods by which other naturally occurring  substances (such as amino
acids) are synthetically produced.

The HPSI Technology

         Pheromones. People have long known that insects and animals communicate
with one another through subtle,  biochemical  cues recognized and understood by
other members of the same  species.  These  biochemical  signals warn of danger,
indicate the presence of food,  mark  territorial  boundaries and display sexual
maturation  or  readiness.   The  biochemical   messengers  that  deliver  these
communications  are  pheromones.  Pheromones  trigger  a  nerve  impulse  to the
hypothalamus when applied within or adjacent to the nasal passages.

         Scientists  have  observed  that in higher  species  the  influence  of
pheromones  grows  increasingly  more  subtle  and  complex.  Not  surprisingly,
reactions to pheromones are very subtle in human beings.  While humans appear to
have definite  responses to pheromones,  the research sponsored by HPSI suggests
that the highly developed human brain filters and masks those reactions.  Rather
than producing an isolated effect,  as in lower level species,  human pheromones
act in concert with other sensory cues provided by odor, sight, taste, sound and
touch to provide a cumulative influence.

         As a result of its sponsored  research,  the Company believes  evidence
has been developed that indicates that humans respond to human pheromones.  HPSI
has also found that its human pheromones are sexually  dimorphic:  that is, some
are more  active in females  while  others  show a higher  level of  activity in
males. During the studies of human pheromones conducted by the Company,  certain
human subjects  volunteered  descriptions  of their feelings.  Women  frequently
described  feeling  comfortable  or at  ease,  while a number  of male  subjects
described a feeling of confidence and self-assurance. The

Company continues to explore these naturally  occurring  substances in a variety
of tests to increase its knowledge and understanding of their range of influence
on  human  emotions  and  their  application  as  components  of fine  fragrance
products.

         Fragrances  and  Pheromones.  Animal  pheromones  are well known in the
fragrance industry.  Natural and synthetic  equivalents of mammalian  pheromones
such as musk,  civet and castoreum are found in many  perfumes  today.  However,
since  pheromonal  cues can  trigger  a  response  only by  members  of the same
species,  these animal  pheromones have no specific  effect on humans;  instead,
they act only as fixatives  or carriers  for the  fragrance or as a component of
the scent.

         A scent binds to smell  receptors in the nose and stimulates a specific
region of the brain  resulting in the sensation of smell.  A pheromone  binds to
separate  receptors  that are physically  and  functionally  distinct from smell
receptors.  These pheromone  receptors stimulate a region of the brain different
from  that  stimulated  by smell  receptors.  Since it is widely  believed  that
traditional  perfumes allure and intrigue the senses,  an alliance  between fine
fragrances  and pheromones  seems quite natural.  For a perfume to create a true
pheromonal effect in humans, however, it must contain human pheromones.  Thus, a
fragrance containing human pheromones may provide more allure than a traditional
fragrance.

         The Vomeronasal  Organ.  The VNO consists of two tiny sensory organs --
one in each  nasal  passage.  The VNO had  been  identified  earlier  in  animal
species,  from  reptiles  to  mammals,  and has been known for some time to be a
receptor for pheromones in animals. In humans,  however,  the VNO was assumed to
be a non-functioning,  vestigial remnant,  rarely even present in modern-day men
and women.

         Over the course of their work on human pheromones,  scientists  working
on  behalf  of HPSI  believe  they  have  made a  further,  important  discovery
concerning the VNO. Not only is the VNO present in all normal adults, it appears
to be an active,  functional  receptor  for human  pheromones.  This has allowed
scientists  engaged on behalf of HPSI to track the activity of human  pheromones
by measuring the changes in the  neuroelectric  potential of the VNO's  receptor
cells caused by  pheromones.  To measure these changes in humans,  a proprietary
noninvasive method is utilized to measure the electrical  response of the VNO in
a way  similar  to how  electrical  responses  of the heart are  recorded  by an
electrocardiogram.

The HPSI Products

         Products.  The  Company  operates in one  business  segment and markets
three fragrances,  REALM(R) Women, REALM(R) Men and inner REALM(R). These "proof
- -of-concept"  products  include  a full  line of  fragrance  and  bath  and body
products including eau de toilette,  cologne,  eau de parfume,  lotion, bath and
shower gel,  after-shave  balm,  antiperspirant,  talc, soap and body cream. The
Company's fragrances were developed by Ann Gottlieb, a leading consultant to the
fragrance  industry.  All  of  the  Company's  products  contain  the  Company's
synthesized  human  pheromones  as a component of the  fragrance.  In 1996,  the
Company introduced a unique refillable,  dripless roll-on applicator  containing
REALM and inner  REALM eau de  toilette  for women,  and in 1998 REALM Women and
REALM Men candles were launched.  In 1999,  the Company  developed a new line of
fragrance and toiletry products containing  synthesized human pheromones for men
and women under the trademark Natural  Attraction(TM).  The company  anticipates
introducing  these products via a new website,  naturalattraction.com,  in April
2000. Initial commercialization of this line of products will be through the web
and other direct marketing channels in the United States.

         Research.   Pheromones  are  chemical  substances  known  to  stimulate
species-specific biological responses in animals. The study of the uses, effects
and  advantages  of human  pheromones  is in its  infancy,  but  abstracts  from
presentations of two recent studies  performed at leading research  universities
reveal new  information  regarding the beneficial  effects of human  pheromones.
Most  interestingly,   these  studies  reveal  new  information   regarding  the
biological pathways human pheromones traverse in the body.  Publication of these
findings  continued  in 1998  and in 1999,  and the  Company  expects  increased
interest in its patented  technology  as the result of these  studies and others
currently being undertaken.

         Scientists  working on behalf of HPSI have  identified and  synthesized
several  naturally  occurring  human  pheromones.  One combination of pheromones
shows a measurable  response in women and another a comparable  response in men.
HPSI has also developed the capability to manufacture  commercial  quantities of
these naturally occurring  substances.  HPSI intends to continue basic pheromone
research as applied to fragrances  and ancillary  products.  For the years ended
December 31, 1999 and 1998,  research and development  expense totaled  $333,000
and $365,000,  respectively.  Since its inception through December 31, 1999, the
Company has incurred $4,296,000 in research and development related expenses.

Markets and Competition

         The Competitive  Environment.  The Company's current fragrance products
contain  what the Company  believes  are unique  components:  human  pheromones.
Consequently,  HPSI believes it will be able to differentiate  its products from
traditional  products.  If such  differentiation  is  successful,  the Company's
products  initially  should have little direct  competition in the  marketplace,
since the Company  believes  no other  companies  in the United  States have the
right to produce or distribute products containing human pheromones. However, if
such  differentiation  is not  successful  the Company will compete  against the
numerous companies in the fragrance industry, including Estee Lauder, Chanel and
the fragrances subsidiaries of Unilever and L'Oreal.

         While  HPSI's  current  products  are  fragrances,  the  Company  feels
strongly  that fine  fragrances  are only a "proof of  concept".  The  Company's
patented human  pheromone  technology has  applications  far beyond  traditional
fragrances and bath and body products.  HPSI hopes to position its technology as
a desired  "value added"  ingredient  for any product that contains a fragrance.
Synthesized  human  pheromones  provide  the  first  patented  technology  of  a
component that could have broad  application  and usage in cosmetic,  treatment,
cleansing,   over-the-counter   health   supplements   and  home   and   vehicle
environmental  products.  The Company does not feel that it has the resources to
successfully  exploit the potential market for such applications and is actively
seeking licensing agreements with consumer product manufacturers.

         Marketing Strategy. HPSI's initial products are a line of fragrance and
bath and body products  containing the Company's  patented human pheromones as a
component. The first of these "proof of concept products" were developed in 1993
when the Company developed REALM Women and REALM Men. While new product launches
in the fragrance  industry  frequently  require  considerable  expenditures  for
promotional  programs which attempt to establish product  differentiation  based
upon  imagery  alone,  HPSI  sought to  develop a program  in 1993  following  a
different  approach -- one that relied on the human  pheromone  component in its
fragrances for product differentiation.

         The  Company's  initial  marketing  program  was  intended  to  educate
consumers  and  the  trade  about   pheromones  while  suggesting  the  enhanced
sensuality  that the wearer of an HPSI  fragrance  might feel.  The Company also
used packaging,  pricing and distribution channels to communicate the uniqueness
of their products and to differentiate them from traditional fragrance products.
The Company  launched its REALM products  through direct marketing to ensure the
quality  and  clarity  of  the  HPSI  message  and  thereafter   moved  to  more
conventional fragrance channels based on criteria such as store location,  image
and promotional support.

         Distribution  and  Promotional  Activities.  During  1993,  the Company
developed two fragrances,  REALM Women and REALM Men, each presented in 50ml and
5ml sizes. Initial promotion and distribution was in the form of a one half-hour
infomercial,  broadcast-tested  in August 1994 and rolled-out  nationally in the
last four months of the year. The infomerical  continued to be broadcast through
mid-1995  while the Company  commenced  selling its  products in the  U.S.retail
department stores on a limited basis in late 1994.

         By the  beginning  of 1997,  HPSI was still a single  product  company,
primarily involved in one class of trade -- better U.S. department stores. REALM
fragrances  and  toiletries  were  available in more than 1,300 stores in the 48
contiguous  states.  While this is the largest channel of distribution for basic
fragrances,  the high level of retailer  employee  turnover  required  expensive
ongoing training for continued success of differentiated,  scientifically  based
products  such as REALM  fragrances.  In  addition,  HPSI  provides  significant
in-store fragrance modeling to ensure that consumers driven to the stores by the
Company's  ongoing  radio   advertisements  have  the  opportunity  to  actually
experience REALM products once they reach the store.

         To lessen its dependence on a single class of trade and in an effort to
leverage the expense of its radio advertising and promotion, the Company entered
into agreements with  distributors  who focus on the fast growing  perfumery and
middle market  department  store classes of trade.  These  alternative  channels
provide  additional  exposure for the  Company's  products  and human  pheromone
technology at a significantly  lower cost than the better department  stores. In
mid-1997,  the Company  introduced a second women's  fragrance line,  innerREALM
initially  to the  department  store class of trade.  Results of this  expensive
product launch were disappointing.  A decision was made to reposition this brand
to the  alternative  channels of  distribution  in 1998,  and  results  from the
initial  repositioning  are  encouraging.  During  1998,  the Company  continued
distributing  its  REALM  Men and  REALM  Women's  fragrances  in  leading  U.S.
department stores,  while substantially  completing the transfer of the sale and
marketing  of  innerREALM   fragrances  to   alternative   markets  -  including
perfumeries and middle market department stores.  These alternative  markets are
handled by an independent distributor who purchases the product from the Company
without  the right of return and is  responsible  for  advertising,  selling and
marketing  expenses.  By focusing the innerREALM product line on these secondary
markets,  the Company reduced its dependence on the department  stores for sales
to the U.S.  consumer.  The Company  reorganized it's U.S. sales organization in
the last  quarter of 1998.


                                       4

<PAGE>

Responsibility   for  selling  and  marketing  to  the  department   stores  was
transferred from Company personnel to an independent  organization  comprised of
senior managers with significant  experience introducing and managing fragrances
in this class of trade.  This group is  compensated  by  commission on net sales
generated. One of the principal's of this organization had been and continues to
be the CEO of  Northern  Brands,  the  Company's  distributor  in the  secondary
markets.  Also, in late 1998 the Company determined that it could not profitably
continue doing business with the May Company and ceased selling products to this
retailer and its subsidiaries at such time.

         To further reduce its dependence on a single market, the Company sought
to increase  its  non-U.S.  distribution.  In 1995 and 1996,  HPSI  entered into
distribution  agreements  for the sale of REALM  fragrances  and  toiletries  in
selected Middle East markets, including Saudi Arabia and the Gulf States as well
as selected Duty Free markets in the Caribbean, South America and on the Mexican
and Canadian borders. In 1997, additional South American markets were opened and
discussions were undertaken for the profitable sale of REALM products in several
European  markets and the Far East. In early 1998,  initial  shipments were made
under distribution  agreements with distributors in Switzerland and the People's
Republic of China.  Also in 1998,  initial  shipments were made to a distributor
for the sale of the  Company's  products in Spain and  Portugal.  The  Company's
direct foreign sales represented approximately 6.1% and 6.3% of net sales during
1999 and 1998, respectively. International expansion will continue to be a focus
of HPSI.  The  Company is very  conscious  of the fact that  numerous  brands of
prestige  fragrances  have suffered  immeasurable  harm due to diversion by gray
marketers. While realizing that certain levels of such diversion are inevitable,
the Company hopes to curtail the risk of its REALM  products being diverted back
into the U.S. by gray market  discounters  by selecting  duty free  partners who
purchase  realistic  quantities  for  sale in the  regions  they  service.  Such
partnership  agreements are subject to  cancellation  if  significant  diversion
occurs.

         During  1999,  the  Company  continued  to reduce its  presence in U.S.
retailers  whose business was not profitable to HPSI. It also began a program to
more  tightly  focus  advertising,  selling  and  promotional  efforts  with the
remaining  retail  accounts  and did  reduce  its loss on sales to this class of
trade as compared with prior periods.  During 1999,  three  customers  comprised
33%, 20% and 17% of the Company's  total net sales.  However,  the Company still
believes that it is difficult for a niche  marketer to generate  earnings in the
highly competitive fragrance market.

Technology Licensing and Supply Agreements

         One of the strategic  objectives of the company is to expand the use of
its  patented  human  pheromone  technology  by working  closely  with  consumer
products  companies  who are leaders in their  particular  markets.  In December
1998, HPSI signed its first agreement to supply its synthesized human pheromones
to a major cosmetics and fragrance  company.  Revenues  commenced in 1999. Total
revenues  from this  agreement and another  signed later in the year  aggregated
$989,000.  HPSI is also in supply and /or  licensing  discussions  with  several
other companies.

Patents and Other Intellectual Property

         In December  1993 and January  1994,  the Company  received  two United
States  patents  for  non-therapeutic   compositions  of  fragrances  and  human
pheromones  for use as  components  in perfumes and personal  care  products and
consumer and  industrial  products such as clothing,  air  fresheners  and paper
products.  European patents regarding these compositions have been filed and are
pending.  In 1995,  patents  were granted in Taiwan,  and in 1997,  patents were
granted in Mexico.  In June 1998,  the Company was granted a Notice of Allowance
of its patents for the inclusion of synthesized human pheromones by the European
Patent Office. Individual country patents are pending issuance. HPSI is also the
exclusive licensee for  non-therapeutic  uses of pheromones in consumer products
under a royalty-free  world-wide  perpetual license to five United States patent
applications  covering pheromone  technology owned by Pherin  Corporation.  This
technology is also the subject of foreign patent applications.  The Company also
relies on trade secrets protection for confidential and proprietary information.
Other patent applications are currently in process.

Regulation

         Unless  the  FDA  extends  its  regulatory  authority,   regulation  by
governmental  authorities  in the  United  States  and  other  countries  is not
expected  to be a  significant  consideration  in  the  sale  of  the  Company's
fragrance products and in its ongoing research and development activities. Under
current  regulations,  the market  introduction of the majority of non-medicated
cosmetics products does not require prior formal registration or approval by the
FDA,  although  this could  change in the  future.  The  cosmetic  industry  has
established  self-regulating  procedures  and most  companies  perform their own
toxicity  and  consumer  tests.   Voluntary  filings  related  to  manufacturing
facilities  are made with the FDA. The Cosmetics  Division of the FDA,  however,
does monitor closely problems of safety, adulteration and labeling. In addition,
if the FDA should  determine  that claims made by the Company for its fragrances
involve  the cure,  mitigation  or  treatment  of  disease,  the


                                       5

FDA could take regulatory action against the Company and its products.

         In  addition,  the  United  States  Federal  Trade  Commission  ("FTC")
monitors  product  claims made in  television  and radio  commercials  and print
advertising to ensure that any claim can be  substantiated.  If the FTC believes
that any  advertising  claim made by the  Company  with  regard to the effect or
benefit of its products is not  substantiated  by adequate  data or research and
the Company cannot support such claim, the FTC could also take regulatory action
against the Company and its products.

Employees

         At March 1, 2000,  the Company had  fourteen  full-time  employees.  In
addition,  the Company  retains  consultants  to provide  advice in the areas of
sales and marketing,  public  relations,  advertising,  product safety  testing,
regulatory compliance, MIS and product development.  The Company also has access
to scientific and professional  consultants,  some of whom are retained directly
by Pherin  Pharmaceuticals,  Inc., and who undertake projects for the Company by
virtue of the Company's  agreement with Pherin.  None of the Company's employees
is  represented by a labor union.  The Company  considers its relations with its
employees and consultants to be good.

Manufacturing

         The Company is dependent on third parties to manufacture  its fragrance
products.  The Company has selected two  essential oil  companies,  that provide
fragrance  products  to the  industry,  to  supply  such  compounds  to  HPSI in
accordance with proprietary  formulas developed for the Company. The Company has
agreements in place with  suppliers for its  fragrances  and has been  furnished
with  commercial  quantities  of the  Company's  products for sale to consumers.
While the Company is responsible  for blending the human  pheromones  with these
fragrances,  final bottling and packaging of the fragrance and ancillary product
lines are performed by independent  manufacturers.  These manufacturers selected
by HPSI have extensive experience in blending,  filling and packaging fragrance,
cosmetic and related  products,  and have the capacity to satisfy the  Company's
manufacturing  needs, at least for the foreseeable  future. The Company believes
that such manufacturing  services are widely available to the fragrance industry
at  competitive  prices and has  identified  additional  contract  manufacturing
companies.

         The Company and Pherin are parties to an  agreement  under which Pherin
will supply HPSI with its reasonable  requirements of human  pheromones and will
make  available to HPSI the basic  manufacturing  technology.  At any time after
January 31,  1996,  rather  than supply  human  pheromones  to HPSI,  Pherin may
instead  elect to provide to the Company  all  manufacturing  technology  in its
possession that it has not previously  supplied to HPSI. Through 1998 only small
quantities  of  human  pheromones,  which  could  be  produced  in a  laboratory
environment, were required for its fragrance and ancillary products. As a result
of the initial third party supply  agreement  entered into in December 1998, the
Company  requires   significantly  more  production  of  the  synthesized  human
pheromones  than were  needed in the past.  In  January  1999,  HPSI and  Pherin
contracted with two independent  laboratories to manufacture kilogram quantities
of the synthesized human pheromones under the direction of scientists working on
behalf of the Company and Pherin.  HPSI received  initial  quantities from these
independent  laboratories  commencing  March 1999.  The Company does not believe
that it would be  economically  feasible  to  establish  it's own  manufacturing
facilities  since  synthesized  human  pheromones  are  available  from chemical
laboratories who now have experience in the preparation of these compounds.

Risk Factors

         The  Company's  future  results  may be affected to a greater or lesser
degree by the following factors among others:

         The  Company  may  not be  able  to  effectively  compete  with  larger
companies  or with new  products.  The  prestige  fragrance  market is extremely
competitive.  Many  fragrance  products  are  better  known  than the  Company's
products and compete for  advertising and retail shelf space.  Many  competitors
have  significantly  greater  resources  that will  allow  them to  develop  and
introduce new competing products or increase the promotion of current products.

         The  product  life cycle of a  fragrance  can be very  short.  Changing
fashions  and fads can  dramatically  shift  consumer  preferences  and demands.
Traditional  fragrance  companies  introduce a new  fragrance  every year or so.
Changing  fashions and new products may reduce the chance of creating  long term
brand loyalty to the Company's products.


                                       6

<PAGE>

         The Company's marketing strategy may not be successful. The Company may
not be able to  establish  and  maintain the  necessary  sales and  distribution
channels.  Retail  outlets and  catalogs  may choose not to carry the  Company's
products.  The Company may not have sufficient funds to successfully  market its
products if the current marketing strategy is not successful.

         The  current  retail  environment  may cause  pricing  and  promotional
pressures. Five companies,  Federated Department Stores, The May Company, Dayton
Hudson/Marshall   Fields  ,  Dillard   Department   Stores  and  Saks  (formerly
Proffitts),  own the majority of upper end department  stores.  Because of their
market share,  each company will have  significant  power to determine the price
and  promotional  terms that the Company must meet in order to sell its products
in the company's department stores.

         Upper end  department  stores face  increasing  competition by discount
perfumeries,  drug  chains  and  lower  priced  department  stores  for sales of
fragrances  and  cosmetics.  To compete,  upper end  department  stores have cut
inventories,  reduced co-op advertising, and increased promotions. These tactics
may  force  the  Company  to  reduce  its  prices  or  increase  the cost of its
promotions.

         Seasonality  in sales  may cause  significant  variation  in  quarterly
results.  Sales in the  fragrance  industry are  generally  seasonal  with sales
higher in the second half of the year  because of  Christmas.  This  seasonality
could  cause  a  significant  variation  in the  Company's  quarterly  operating
results.

         The Company may not be able to protect its technology or trade secrets.
The  Company's  patents and patent  applications  may not protect the  Company's
technology or ensure that the Company's  technology does not infringe  another's
valid  patent.  Others  may  independently   develop  substantially   equivalent
proprietary information.  The Company may not be able to protect its technology,
proprietary information or trade secrets.

         The Company may not be able to recruit  and retain key  personnel.  The
Company's  success  substantially  depends upon  recruiting  and  retaining  key
employees and  consultants  with  research,  product  development  and marketing
experience.  The Company may not be successful in recruiting and retaining these
key people.

         The Company relies upon other  companies to  manufacture  its products.
The  Company  relies  upon  Pherin  and  other   companies  to  manufacture  its
pheromones,  supply  components,  and to blend,  fill and package its  fragrance
products.   The  Company  may  not  be  able  to  obtain  or  retain  pheromones
manufacturers,  fragrance  suppliers,  or component  manufacturers on acceptable
terms.  If not, the Company may not be able to obtain  commercial  quantities of
its products. This would adversely affect operating results.


Item 2.  Description of Property

         The Company presently leases  approximately 8,780 square feet of office
and warehousing space for its headquarters in Fremont, California, pursuant to a
lease which  expires on October 31, 2000,  and which is currently  cancelable by
the  Company on 90 days  written  notice and paying a $15,000  cancellation  fee
which  may be waived  under  certain  circumstances.  The  annual  base rent was
approximately  $116,774  for the 12 months  ended  December 31, 1999 and will be
$100,970 in 2000,  unless the lease is  terminated  earlier than its  expiration
date of October 31, 2000.  Total rent expense may be increased by the  Company's
proportional share of any escalation  related to taxes,  common area charges and
outside maintenance incurred by the complex in which the facility is located. In
July 1998, the Company entered into an agreement to sublease approximately 5,890
feet of  warehousing  space  under  substantially  the same terms as its primary
lease..  Such  sublease  expired on November 1, 1999.  In addition,  the Company
leases approximately 8,000 square feet of warehousing and distribution space, at
a cost of $0.60 per square foot, from an independent company under a fulfillment
agreement  cancelable  with 90 days notice.  During the year ended  December 31,
1999, the Company incurred  $120,175 in net rent expense and related charges for
these facilities.

of record of the Company's  Common Stock.  The Company believes that there are a
significant  number of  beneficial  owners of its Common  Stock whose shares are
held by  nominees  in  "Street  Name".  Set forth  below is the high and low bid

Item 6.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

         Year ended  December 31, 1999 compared with the year ended December 31,
1998

         Net sales for the year ended December 31, 1999 were $9,306,000 compared
to $10,379,000 for the prior year. Net sales to department  stores in the United
States  decreased  approximately  $2,509,000 in 1999,  attributable to continued
weakness in the department store fragrance category, the elimination of sales to
unprofitable  retailers and the cessation of  innerREALM(R)  sales to the better
department  stores. In the last six months of 1998, the Company decided to cease
doing  business  with  certain  upscale  U.S.   Department  store  chains  whose
promotional  demands had become so excessive that the business with these stores
was unprofitable; in 1999, additional unprofitable stores were terminated. These
decisions were based on the Company's  goal to focus on bottom line  improvement
even if  total  revenues  declined.  Revenue  of  approximately  $1,690,000  was
generated  from  these  stores  in 1998.  Sales  to  distributors  handling  the
Company's  products in the  secondary  markets in the United  States  (mid-level
department stores,  perfumeries and selected mass market accounts)  increased by
15% in 1999.  While these  distributor  sales bear a lower selling  price,  they
result  in  the  generation  of  operating  profits  since  the  distributor  is
responsible  for  absorbing  all  sales  returns,  advertising  and  promotional
expenses. In 1999, the Company began receiving revenues from sales and licensing
of its  patented  human  pheromone  technology,  generating  revenues  of almost
$1,000,000. In the aggregate,  sales to catalogs and via direct marketing in the
United States and sales to International distributors increased by 11% in 1999.

         Gross margin in 1999  represented  61% of sales as compared with 68% in
the prior year. The decrease was attributable to a higher percentage of sales of
lower gross margin value sets to U.S.  Department  stores and increased sales to
the lower margin  secondary class of trade in 1999. The secondary  market sales,
while reflecting lower gross margin, can have a better contribution to operating
profit since they do not require the level of financial  support for advertising
and marketing that the department stores demand.  In addition,  the gross margin
on revenues  generated by the supply of pheromones  is slightly  lower than that
generated by sales to  department  stores;  however,  virtually all of the gross
profit  generated by such revenue becomes  operating profit since no promotional
spending is required.  As more revenue is generated from pheromone licensing and
supply  agreements,  gross  margin may  decline  but  operating  results  should
improve.


                                       8

<PAGE>

         Research and development  costs in 1999 decreased  slightly to $333,000
from  $365,000  in the prior year.  This  reduction  is  primarily a result of a
reduction in the monthly contractual R&D payments to Pherin Corporation.

         Selling,  general  and  administrative  expenses  declined  by 34%  and
represented  65% of sales  as  compared  with 89% of sales in 1998.  On a dollar
basis, expenditures decreased $3,156,000,  with all spending categories lower in
1999  than the prior  year.  Selling/Advertising  and  marketing  expenses  were
reduced by $2,908,000;  this significant decline is attributable to more focused
advertising  efforts in the remaining  department  stores and the elimination of
promotional spending with non-profitable department store accounts.

         Other expense  increased to $104,000 from $53,000 in 1998,  primarily a
result of higher average bank  borrowings and higher  interest rates  associated
therewith.

         The Company recorded no income tax provision in either 1999 of 1998 due
to the net operating losses generated.

         As of December 31, 1999, the Company's gross deferred tax asset,  which
relates primarily to net operating loss carryforwards,  was $6,692,000. However,
a full  valuation  allowance  was provided  for the gross  deferred tax asset as
management could not determine whether its realization was more likely than not.


Seasonality

         Sales in the  fragrance  industry  are  generally  seasonal  with sales
higher in the  second  half of the year  because  of the  Holiday  period.  This
seasonality  could cause a  significant  variation  in the  Company's  quarterly
operating results.


Liquidity

         At December 31, 1999, the Company had cash and  cash-equivalents  equal
to $108,000 and working  capital of  $2,052,000.  These balances at December 31,
1998 were  $77,000  and  $2,351,000  respectively.  Net cash  used in  operating
activities  was $596,000 and $988,000 for the years ended  December 31, 1999 and
1998,  respectively.  The decrease in net cash used in operating  activities  in
1999 as compared with 1998 was  principally due to a decrease in the net loss in
1999.  Issuance of convertible  preferred  stock to a long-term  investor in the
amount of $550,000 in 1999, and $600,000 in 1998 partially  offset cash usage in
1999.  Other cash  infusion was from bank  borrowings in the amounts of $127,000
and $225,000 for 1999 and 1998,  respectively.  At December 31, 1999, borrowings
against the Company's $3,000,000 line of credit were $900,000.

         The Company is in  negotiations  for the license of the Company's REALM
and innerREALM  product lines for a ten-year period.  Additional working capital
may be  required  should the  Company  fail to complete  the  transaction  being
negotiated.  Also,  additional  working  capital  may be  required  to  generate
anticipated  consumer  response  levels at  comparable  levels to 1999 or if the
Company  experience a greater than  planned  success with its current  products,
potential  product  line  extensions  and  efforts.  Funds  would be needed  for
inventory build,  accounts  receivable  financing and staffing purposes.  If the
Company fails to achieve significant revenues from its 2000 marketing efforts or
if expansion proves to be more capital  intensive than planned,  the Company may
require additional funding. The Company obtained an additional $260,000 from the
sale of convertible preferred stock in March 2000.

         The Company's  Business Loan Agreement with  Mid-Peninsula Bank of Palo
Alto,  California  ("the Bank")  expires on April 1, 2000. The Bank has extended
the line of credit for a three month period  ending June 30,  2000.  The Company
may borrow up to  $1,500,000  at an interest rate equal to the Bank's prime rate
plus 1.0 % with borrowings  secured primarily by the Company's trade receivables
and inventory. The agreement contains certain debt-to-equity and working capital
covenants.  If the transaction  being negotiated is not successfully  completed,
the Company may need to seek  alternative  bank  financing,  using its assets as
collateral.

New Accounting Pronouncement

         In June 1998,  the FASB issued SFAS No. 133,  Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 requires companies to recognize
all  derivatives  contracts as either assets or liabilities in the balance sheet
and to measure them at fair value.  If certain  conditions are met, a derivative
may be  specifically  designated as a hedge,  the objective of which is to match
the  timing  of gain or loss  recognition  on the  hedging  derivative  with the
recognition of (i) the


                                       9

<PAGE>

change in the fair value of the hedged asset or liability that are  attributable
to the  hedged  risk  or (ii)  the  earnings  effect  of the  hedged  forecasted
transaction.  For a derivative not designated as a hedging instrument,  the gain
or loss is  recognized  in income in the  period of  change.  SFAS No.  133,  as
amended by SFAS No. 137, is  effective  for all fiscal  quarters of fiscal years
beginning after June 15, 2000.

         The Company has not entered into derivatives  contracts either to hedge
existing risks or for speculative  purposes.  Accordingly,  the Company does not
expect  adoption of the new standard on January 1, 2001 to affect its  financial
statements

Impact of the Year 2000

         Many currently  installed  computer  systems and software  products are
coded to accept or  recognize  only two digit  entries  in the date code  field.
These  systems may  recognize a date using "00" as the year 1900 rather than the
year 2000. As a result,  computer systems and/or software used by many companies
and  governmental  agencies  may need to be  upgraded  to comply  with year 2000
requirements or risk system failure or  miscalculations  causing  disruptions of
normal business activities.

         State  of  Readiness.  Although  as  of  March  1,  2000,  the  Company
experienced no material technical problems related to the year 2000, the Company
shall  continue to seek  verification  from our key  vendors,  distributors  and
suppliers  that  they are year 2000  compliant.  To date,  however,  none of the
Company's systems have needed to be revised or replaced.

         Costs.  To date, we have not incurred any material costs in identifying
or evaluating year 2000 compliance issues. Most of our expenses have related to,
and are  expected to continue to relate to, the upgrades or  replacements,  when
necessary,  of software or hardware, as well as costs associated with time spent
by  employees  in the  evaluation  process  and  year  2000  compliance  matters
generally. These expenses are included in our capital expenditures plans are not
expected  to be  material  to the  Company's  financial  position  or results of
operations.  These expenses,  however, if higher than anticipated,  could have a
material and adverse effect on our business, results of operations and financial
condition.

         Risks.  Although  as of  March  1,  2000  we  experienced  no  material
technical  problems related to the year 2000, there can be no assurance that the
Company will not discover year 2000 compliance problems in its systems that will
require substantial revisions or replacements. In the event that the operational
facilities that support the Company's  business are not year 2000 compliant,  it
may be unable to deliver goods or services to customers. In addition,  there can
be no assurance that  third-party  software,  hardware or services  incorporated
into the  Company's  material  systems  will not need to be revised or replaced,
which could be time-consuming and expensive.  The Company's  inability to fix or
replace  third-party  software,  hardware or  services  on a timely  basis could
result  in  lost  revenues,   increased   operating  costs  and  other  business
interruptions,  any of which  could have a material  and  adverse  effect on the
Company's business, results of operations and financial condition. Moreover, the
failure to  adequately  address  year 2000  compliance  issues in the  software,
hardware or systems could result in claims of  mismanagement,  misrepresentation
or breach  of  contract  and  related  litigation,  which  could be  costly  and
time-consuming to defend.

         In addition,  there can be no  assurance  that  governmental  agencies,
utility  companies,  Internet access  companies and others outside the Company's
control will be year 2000  compliant.  The failure by these  entities to be year
2000  compliant  could  result  in a  systematic  failure  beyond  our  control,
including,  for example, a prolonged Internet,  telecommunications or electrical
failure,  which could also prevent the Company from  delivering  services to its
users,  decrease the use of the  Internet or prevent  users from  accessing  the
Company's services, any of which would have a material and adverse effect on the
Company's business, results of operations and financial condition.

         Contingency  Plan.  As  discussed  above,  the Company is engaged in an
ongoing year 2000  assessment and does not currently have a contingency  plan to
deal with the worst case scenario that might occur if  technologies on which the
Company  depends  are not year 2000  compliant  and fail to operate  effectively
after  the  year  2000.  The  results  of the  Company's  year  2000  compliance
evaluation  and the responses  received from  distributors,  suppliers and other
third  parties  with  which the  Company  conducts  business  will be taken into
account in  determining  the need for and  nature and extent of any  contingency
plans.

         If the Company's  present  efforts to address the year 2000  compliance
issues  discussed above are not successful,  or if  distributors,  suppliers and
other third parties with which the Company conducts business do not successfully
address such issues, the Company customers could seek alternate suppliers of our
products and services.  Any material year 2000 problem could require the Company
to incur  significant  unanticipated  expenses  to remedy  and could  divert the
Company's management's time and attention, either of which could have a material
and adverse efect on the  Company's  business,  operating  results and financial
condition.

      Report of BDO Seidman, LLP, Independent Certified Public Accountants



To the Board of Directors and Shareholders
Human Pheromone Sciences, Inc.

         We have audited the accompanying  consolidated  balance sheet  of Human
Pheromone Sciences,  Inc. as of December 31, 1999, and the related  consolidated
statements of operations and comprehensive loss,  shareholders'  equity and cash
flows  for the year  ended  December  31,  1999.  These  consolidated  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audit.

         We conducted our audit 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 audit provides 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 Human
Pheromone Sciences, Inc. at December 31, 1999, and the results of its operations
and its cash flows for the year ended  December 31,  1999,  in  conformity  with
generally accepted accounting principles.

                   Notes to Consolidated Financial Statements
                                December 31, 1999

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Nature of Operations

         Human Pheromone Sciences,  Inc. (the "Company") was incorporated in the
State of  California  in 1989 under the name of EROX  Corporation.  The  Company
changed the name to Human Pheromone  Sciences,  Inc. in May 1998. The Company is
engaged in the research,  development,  manufacturing  and marketing of consumer
products  containing  synthetic  human  pheromones  as a component.  The Company
initiated commercial  operations in late 1994 with a line of fine fragrances and
toiletries.  The Company  currently sells its REALM fragrance  products  through
department   and  specialty   stores  across  the  United  States  and  selected
international markets.

Principles of Consolidation

The accompanying  consolidated  financial statements include the accounts of the
Company and its wholly owned subsidiary in France. All significant  intercompany
accounts and transactions have been eliminated.

Use of Estimates

         The  preparation  of  the  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  revenue  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Segment Reporting

         During the year ended  December 31, 1999,  the Company began  receiving
revenues from sales and licensing of its patented  human  pheromone  technology.
Currently,  the Company's management does not regularly review operating results
relating  to this  revenue,  nor does it assess its  performance  by  allocating
various  expenditures.  Consequently,  it will not  report  this  revenue  as an
individual  segment.  As the  Company's  sales  and  licensing  revenues  of its
patented human pheromone technology progresses, it will begin to develop systems
to monitor this segment, and report its results accordingly.

         The Company's  direct sales in  international  markets is not material.
Accordingly,  the Company will not report international  markets as a geographic
segment.

Concentration of Credit Risk

         The  Company's  concentration  of credit risk consists  principally  of
cash, cash equivalents and trade receivables.  Concentration of credit risk with
respect to trade  receivables  is limited  because the  Company's  customer base
consists of a large number of geographically diverse customers in the department
and  specialty  store  trade,  in the United  States and  various  international
markets.  On-going  credit  evaluations  of customers'  financial  condition are
performed and  generally,  no collateral is required.  The company  maintains an
allowance  for  potential  losses  based upon  management  analysis  of possible
uncollectable accounts.

Customer Concentration

         During  1999,  three  customers  comprised  33%,  20%  and  17%  of the
Company's net sales.  During 1998,  two  customers  comprised 22% and 16% of the
Company's net sales.

Supplier Concentration

         The Company is dependent on third parties to manufacture  its fragrance
products,  as well as the synthesized  human  pheromones used in these products.
Capacity  limitations at these  essential  suppliers,  or any other  occurrences
leading to an interruption of supply could have a material adverse effect on the
Company.

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Revenue Recognition

         Revenue  is  recorded  at the  time  of  merchandise  shipment,  net of
provisions  for returns.  License fees are earned  according to the terms of the
license  agreement and the license.  The majority of the Company's  sales are to
large department store chains.

Advertising Expense

         The cost of advertising is expensed as incurred. Advertising costs were
$1,108,000 and $2,160,000 in 1999 and 1998, respectively.

Research and Development

         Research and  development  costs are charged to expense when  incurred.
Research  and  development  costs were  $333,000  and $365,000 in 1999 and 1998,
respectively.

Fair Value of Financial Instruments

         The  Company   believes  the  book  value  of   financial   instruments
approximates their fair value.

Long-term Assets

         The company  applies SFAS No. 121,  "Accounting  for the  Impairment of
Long-Lived Assets". Under SFAS No.121, long-lived assets and certain intangibles
are evaluated for impairment  when events or changes in  circumstances  indicate
that the carrying value of the assets may not be recoverable  through  estimated
undiscounted  future cash flows resulting from the use of these assets. When any
such impairment exists, the related assets will be written down to fair value.

Income Taxes

         The Company  follows the  provisions of SFAS No. 109,  "Accounting  for
Income  Taxes",  which  requires  use of the  "liability  method".  Accordingly,
deferred  tax  liabilities  and assets  are  determined  based on the  temporary
differences  between  the  financial  statement  and tax  bases  of  assets  and
liabilities,  using  enacted  tax  rates in  effect  for the  year in which  the
differences are expected to reverse.

Stock Options

         The Company  applies  Accounting  Principles  Board Opinion ("APB") 25,
"Accounting  for Stock  Issued to  Employees",  and related  Interpretations  in
accounting  for all  stock  option  plans.  Under APB 25,  compensation  cost is
recognized  for stock  options  granted at prices  below the market price of the
underlying common stock on the date of grant.

         SFAS No. 123, "Accounting for Stock - Based Compensation", requires the
Company to provide pro forma information regarding net income as if compensation
had been determined in accordance with the fair value based method prescribed in
SFAS No. 125.

Comprehensive Income

         Comprehensive  income is comprised of net income and all changes to the
statements  of  shareholders'   equity,   except  those  due  to  investment  by
shareholders, changes in paid-in capital and distributions to shareholders.

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Translation of Foreign Currencies

         The  financial  statements  of the  Company's  foreign  subsidiary  are
measured in the local  currency  and then  translated  into U. S.  dollars.  All
balance sheet accounts have been  translated  using the current rate of exchange
at the balance sheet date.  Results of operations have been translated using the
average  rate  prevailing  throughout  the year.  Translation  gains and  losses
resulting from the change in exchange  rates from year- to-year are  accumulated
in a separate account of  shareholders'  equity.  Foreign  currency  transaction
gains and losses are included in consolidated net income.

New Accounting Pronouncement

         In June 1998, the FASB issued SFAS No. 133,  "Accounting for Derivative
Instruments  and  Hedging  Activities".  SFAS  No.  133  requires  companies  to
recognize  all  derivatives  contracts as either  assets or  liabilities  in the
balance sheet and to measure them at fair value. If certain  conditions are met,
a derivative may be specifically  designated as a hedge,  the objective of which
is to match the timing of gain or loss  recognition  on the  hedging  derivative
with the recognition of (i) the changes in the fair value of the hedged asset or
liability that are  attributable  to the hedged risk or (ii) the earnings effect
of the hedged  forecasted  transaction.  For a derivative  not  designated  as a
hedging  instrument,  the gain or loss is  recognized in income in the period of
change.  SFAS No. 133, as amended by SFAS No. 137, is  effective  for all fiscal
quarters of fiscal quarters of fiscal years beginning after June 15, 2000.

         The Company has not entered into derivatives  contracts either to hedge
existing risks or for speculative  purposes.  Accordingly,  the Company does not
expect  adoption of the new standard on January 1, 2001 to affect its  financial
statements.

Net Income/Loss Per Share

         The Company  follows the  provisions  of SFAS No.  128,  "Earnings  Per
Share".  SFAS NO. 128  provides  for the  calculation  of "Basic"  and  Diluted"
earning  per share.  Basic net  income/(loss)  per share is  computed  using the
weighted-average number of common shares outstanding.  Diluted net income/(loss)
per share is computed  using the  weighted-average  number of common  shares and
dilutive  common  shares  outstanding  during the  period.  For the years  ended
December 31, 1999 and 1998,  options to purchase  367,000 and 313,000  shares of
common  stock,  respectively,  were  excluded  from the  computation  of diluted
earnings per share since their effect would be antidilutive.

Cash and Cash Equivalents

         The Company  considers  all highly  liquid  investments  with  original
maturities of three months or less to be cash equivalents.

Inventories

         Inventories  are  stated  at the  lower  of cost  (first-in,  first-out
method) or market.

Property and Equipment

         The  Company's  property  and  equipment  is  stated  at  cost,  net of
accumulated depreciation. Depreciation is provided on a straight-line basis over
three years

4.       BANK BORROWING

         The  Company has a revolving  line of credit with  Mid-Peninsula  Bank,
which expires April 1, 2000.  Under the terms of this loan agreement the Company
may borrow up to 75% of  allowable  accounts  receivable,  as  defined,  up to a
maximum of $3 million.  As of December 31, 1999 $900,000 was outstanding against
the credit line,  and the interest  rate on borrowings is the bank's prime rate,
8.5% at December 31, 1999, plus 1.00%.  Borrowings are primarily  secured by the
Company's accounts  receivable and inventories.  The line of credit requires the
company to  maintain  debt-to-equity  and  liquidity  ratios,  and a minimum net
worth.  As of  December  31,  1999 the  Company  was in  compliance  with  these
financial covenants.


5.       COMMITMENTS AND CONTINGENCIES

         Effective  November 1, 1998,  the Company  extended the existing  lease
arrangement for office space in Fremont,  California until October 31, 2000. The
annual base rent will be approximately $100,970 for the year ending December 31,
2000. The lease also provides for payments related to taxes, common area charges
and outside  maintenance.  In July 1998 the  Company  subleased a portion of the
Fremont  facilities.  The sublease expired October 31, 1999 and required a total
rent of $78,900 including reimbursement of common area charges,  property taxes,
and  maintenance.  The sublease  income is netted  against rent  expense.  Total
rental  expense was $120,175 and $129,400 for the years ended  December 31, 1999
and 1998, respectively.


6.       SHAREHOLDERS' EQUITY

Directors.  Options may be granted at the fair value at the date of the grant as
determined by the Board of  Directors.  Options for a holder of more than 10% of

Stock Compensation

         The Company  applies APB 25 and related  Interpretations  in accounting
for its employee stock options.  Had compensation  expense been determined based
upon the fair  value of the  awards at the grant  date and  consistent  with the
method  under SFAS No.  125,  the  Company's  net loss per share would have been
increased  the  the  proforma  amount  indicated  in  the  following  table  (in

         The Company also retains the consulting services of Dr. David Berliner,

8.       INCOME TAXES

         There was no provision for income taxes for the year ended December 31,
1999 or 1998 as the Company  incurred net operating  losses for which no benefit
was recognized.

         A  reconciliation  of the  effective  tax rate and the  statutory  U.S.
federal income tax rates are as follows:

         At December 31, 1999, the Company had net operating loss  carryforwards
of  approximately  $16,700,000.  The  Company  also  had  federal  research  and
development tax carryforwards of approximately  $187,000. The net operating loss
and credit  carryforwards  will expire between 2004 and 2014. The utilization of
certain of the loss  carryforwards  is limited under Section 382 of the Internal
revenue Code.

         Temporary  differences  that give rise to a significant  portion of the
deferred tax asset are as follows (in thousands):

         Because of the  Company's  lack of earnings  history,  the deferred tax
asset  has  been  fully  offset  by a  valuation  allowance.  The net  valuation
allowance  increased by $292,000 and  $940,000 in 1999 and 1998.  The  valuation
allowance was established  because the Company was not able to determine that is
more likely than not that the deferred tax asset will be realized.

9.       SUBSEQUENT EVENTS (unaudited)

         On March 27, 2000,  the Company  obtained  $260,000  additional  equity
capital from a current  shareholder by issuing  shares of convertible  preferred
stock.

         On March  22,  2000  Mid-Peninsula  Bank  extended  to July 1, 2000 the
revolving line of credit, up to a maximum of $1,500,000.

Loan No 0108143855                (Continued)
================================================================================
         Borrower,  upon request of Lender,  will deliver to Lender from time to
         time the policies or certificates of insurance in form  satisfactory to
         Lender,  including stipulations that coverages will not be cancelled or
         diminished  without at least ten (10)  days'  prior  written  notice to
         Lender.  Each  insurance  policy  also  shall  include  an  endorsement
         providing  that coverage in favor of Lender will not be impaired in any
         way by any act, omission or default of Borrower or any other person. In
         connection  with all policies  covering assets in which Lender holds or
         is offered a security  interest  for the Loans,  Borrower  will provide
         Lender  with such loss  payable  or other  endorsements  as Lender  may
         require.

     Insurance Reports.  Furnish to Lender,  upon request of Lender,  reports on
     each  existing  insurance  policy  showing such  information  as Lender may

     name of the insurer;  (b) the risks insured;  (c) the amount of the policy;
     (d) the properties  insured;  (e) the then current  property  values on the
     basis of which  insurance has been obtained,  and the manner of determining
     those values; and (f) the expiration date of the policy. In addition,  upon
     request of Lender  (however not more often than  annually),  Borrower  will
     have  an  independent  appraiser  satisfactory  to  Lender  determine,   as
     applicable,  the actual cash value or replacement  cost of any  Collateral.
     The cost of such appraisal shall be paid by Borrower.

     Other  Agreements.  Comply  with all  terms  and  conditions  of all  other
     agreements,  whether now or hereafter  existing,  between  Borrower and any
     other  party and notify  Lender  immediately  in writing of any  default in
     connection with any other such agreements.

     Loan  Proceeds.  Use all  Loan  proceeds  solely  for  Borrower's  business
     operations,  unless  specifically  consented  to the  contrary by Lender in
     writing.

     Taxes,   Charges  and  Liens.  Pay  and  discharge  when  due  all  of  its
     indebtedness and obligations, including without limitation all assessments,
     taxes,  governmental  charges,  levies and liens, of every kind and nature,
     imposed upon Borrower or its properties,  income, or profits,  prior to the
     date on which  penalties  would  attach,  and all lawful  claims  that,  if
     unpaid,  might become a lien or charge upon any of  Borrower's  properties,
     income, or profits.  Provided however, Borrower will not be required to pay
     and discharge any such assessment, tax, charge, levy, lien or claim so long
     as (a) the  legality  of the  same  shall  be  contested  in good  faith by
     appropriate  proceedings,  and (b) Borrower  shall have  established on its
     books  adequate  reserves with respect to such contested  assessment,  tax,
     charge,  levy,  lien,  or  claim  in  accordance  with  generally  accepted
     accounting  practices.  Borrower,  upon demand of Lender,  will  furnish to
     Lender  evidence of payment of the  assessments,  taxes,  charges,  levies,
     liens and claims and will authorize the appropriate  governmental  official
     to deliver to Lender at any time a written  statement  of any  assessments,
     taxes,  charges,  levies,  liens and claims against Borrower's  properties,
     income, or profits.

     Performance.  Perform and comply with all terms, conditions, and provisions
     set  forth  in this  Agreement  and in the  Related  Documents  in a timely
     manner,  and promptly notify Lender if Borrower learns of the occurrence of
     any event which  constitutes  an Event of Default  under this  Agreement or
     under any of the Related Documents.

     Operations.  Maintain executive and management personnel with substantially
     the  same  qualifications  and  experience  as the  present  executive  and
     management  personnel;  provide  written  notice to Lender of any change in
     executive  and  management  personnel;  conduct its  business  affairs in a
     reasonable  and  prudent  manner  and in  compliance  with  all  applicable
     federal,  state and  municipal  laws,  ordinances,  rules  and  regulations
     respecting its properties,  charters, businesses and operations,  including
     without limitation, compliance with the Americans With Disabilities Act and
     with all minimum  funding  standards  and other  requirements  of ERISA and
     other laws applicable to Borrower's employee benefit plans.

     Inspection.  Permit employees or agents of Lender at any reasonable time to
     inspect any and all Collateral  for the Loan or Loans and Borrower's  other
     properties and to examine or audit Borrower's books,  accounts, and records
     and to make  copies  and  memoranda  of  Borrower's  books,  accounts,  and
     records.  If Borrower now or at any time  hereafter  maintains  any records
     (including  without  limitation  computer  generated  records and  computer
     software  programs for the generation of such records) in the possession of
     a third party, Borrower, upon request of Lender, shall notify such party to
     permit  Lender free access to such records at all  reasonable  times and to
     provide Lender with copies of any records it may request, all at Borrower's
     expense.

     Compliance Certificate.  Unless waived in writing by Lender, provide Lender
     at least  annually and at the time of each  disbursement  of Loan  proceeds
     with a certificate executed by Borrower's chief financial officer, or other
     officer or person acceptable to Lender, certifying that the representations
     and  warranties  set forth in this Agreement are true and correct as of the
     date of the certificate and further  certifying that, as of the date of the
     certificate, no Event of Default exists under this Agreement.

     Environmental Compliance and Reports. Borrower shall comply in all respects
     with all environmental  protection federal, state and local laws, statutes,
     regulations and ordinances; not cause or permit to exist, as a result of an
     intentional or unintentional  action or omission on its part or on the part
     of any third  party,  on property  owned and/or  occupied by Borrower,  any
     environmental  activity where damage may result to the environment,  unless
     such  environmental  activity  is pursuant  to and in  compliance  with the
     conditions of a permit issued by the  appropriate  federal,  state or local
     governmental authorities; shall furnish to Lender promptly and in any event
     within  thirty  (30)  days  after  receipt  thereof  a copy of any  notice,
     summons, lien, citation,  directive, letter or other communication from any
     governmental  agency  or  instrumentality  concerning  any  intentional  or
     unintentional  action or omission on Borrower's part in connection with any
     environmental  activity  whether or not there is damage to the  environment
     and/or other natural resources.

     Additional Assurances.  Make, execute and deliver to Lender such promissory
     notes,   mortgages,   deeds  of  trust,   security  agreements,   financing
     statements,  instruments,  documents and other  agreements as Lender or its
     attorneys  may  reasonably  request to evidence and secure the Loans and to
     perfect all Security Interests.

NEGATIVE  COVENANTS.  Borrower  covenants and agrees with Lender that while this
Agreement is in effect, Borrower shall not, without the prior written consent of
Lender:

     Indebtedness  and Liens.  (a) Except for trade debt  incurred in the normal
     course  of  business  and  indebtedness  to  Lender  contemplated  by  this
     Agreement,  create,  incur  or  assume  indebtedness  for  borrowed  money,
     including capital leases, (b) sell,  transfer,  mortgage,  assign,  pledge,
     lease,  grant a security interest in, or encumber any of Borrower's assets,

     transfer or sell Collateral out of the ordinary course of business, (c) pay
     any  dividends on  Borrower's  stock (other than  dividends  payable in its
     stock),  provided,  however that notwithstanding the foregoing, but only so
     long as no Event of Default has occurred and is  continuing or would result
     from the payment of dividends,  if Borrower is a "Subchapter S Corporation"
     (as defined in the Internal Revenue Code of 1986, as amended), Borrower may
     pay cash  dividends on its stock to its  shareholders  from time to time in
     amounts  necessary to enable the  shareholders to pay income taxes and make
     estimated  income tax payments to satisfy their  liabilities  under federal
     and state law which arise  solely from their  status as  Shareholders  of a
     Subchapter S Corporation  because of their  ownership of shares of stock of

     enterprise  or entity,  or (c) incur any  obligation as surety or guarantor
     other than in the ordinary course of business.

CESSATION OF  ADVANCES.  If Lender has made any  commitment  to make any Loan to
Borrower,  whether  under this  Agreement or under any other  agreement,  Lender
shall have no  obligation to make Loan Advances or to disburse Loan proceeds if:
(a) Borrower or any Guarantor is in default under

Loan No 0108143855                (Continued)

the  terms  of this  Agreement  or any of the  Related  Documents  or any  other

Guarantor,  or in the value of any  Collateral  securing  any  Loan;  or (d) any

Guarantor's guaranty of the Loan or any other loan with Lender.

ADDITIONAL FINANCIAL REPORTING. Borrower agrees to the following:

Northern  Brands,  Inc. is not completed and this line of credit is not paid off
prior to maturity, we will then require an A/R exam.

EVENTS OF DEFAULT.  Each of the following  shall  constitute an Event of Default
under this Agreement:

     Default on  Indebtedness.  Failure of Borrower to make any payment when due
     on the Loans.

     Other  Defaults.  Failure of  Borrower  or any Grantor to comply with or to
     perform  when  due  any  other  term,  obligation,  covenant  or  condition
     contained in this Agreement or in any of the Related Documents,  or failure
     of  Borrower  to comply  with or to  perform  any other  term,  obligation,
     covenant or condition  contained in any other agreement  between Lender and
     Borrower.

     Default in Favor of Third Parties.  Should  Borrower or any Grantor default
     under any loan, extension of credit, security agreement,  purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect any of Borrower's  property or Borrower's or any
     Grantor's   ability  to  repay  the  Loans  or  perform  their   respective
     obligations under this Agreement or any of the Related Documents.

     False  Statements.  Any  warranty,  representation  or  statement  made  or
     furnished  to Lender by or on behalf of Borrower or any Grantor  under this
     Agreement or the Related  Documents is false or  misleading in any material
     respect at the time made or  furnished,  or becomes  false or misleading at
     any time thereafter.

     Defective Collateralization. This Agreement or any of the Related Documents
     ceases to be in full force and effect  (including  failure of any  Security
     Agreement to create a valid and  perfected  Security  Interest) at any time
     and for any reason.

     Insolvency.  The  dissolution or  termination of Borrower's  existence as a
     going business,  the insolvency of Borrower,  the appointment of a receiver
     for any part of  Borrower's  property,  any  assignment  for the benefit of
     creditors,  any  type  of  creditor  workout,  or the  commencement  of any
     proceeding under any bankruptcy or insolvency laws by or against Borrower.

     Creditor  or  Forfeiture   Proceedings.   Commencement  of  foreclosure  or
     forfeiture   proceedings,   whether  by  judicial  proceeding,   self-help,
     repossession or any other method, by any creditor of Borrower, any creditor
     of any Grantor against any collateral securing the Indebtedness,  or by any
     governmental agency. This includes a garnishment, attachment, or levy on or
     of any of Borrower's deposit accounts with Lender.  However,  this Event of
     Default  shall not apply if there is a good faith  dispute by  Borrower  or
     Grantor,  as the case may be, as to the validity or  reasonableness  of the
     claim which is the basis of the creditor or forfeiture  proceeding,  and if
     Borrower  or  Grantor  gives  Lender  written  notice  of the  creditor  or
     forfeiture  proceeding  and  furnishes  reserves  or a surety  bond for the
     creditor or forfeiture proceeding satisfactory to Lender.

     Events Affecting Guarantor. Any of the preceding events occurs with respect
     to any  Guarantor  of any of the  Indebtedness  or any  Guarantor  dies  or
     becomes  incompetent,  or revokes or disputes the validity of, or liability
     under, any Guaranty of the Indebtedness.  Lender,  at its option,  may, but
     shall  not  be  required  to,  permit  the  Guarantor's  estate  to  assume
     unconditionally  the  obligations  arising  under the  guaranty in a manner
     satisfactory to Lender, and, in doing so, cure the Event of Default.

     Change In Ownership.  Any change in ownership of twenty-five  percent (25%)
     or more of the common stock of Borrower.

     Adverse Change.  A material  adverse change occurs in Borrower's  financial
     condition, or Lender believes the prospect of payment or performance of the
     Indebtedness is impaired.

     Right to Cure.  If any default,  other than a Default on  Indebtedness,  is
     curable and if Borrower or Grantor,  as the case may be, has not been given
     a notice of a similar default within the preceding  twelve (12) months,  it
     may be cured (and no Event of Default  will have  occurred)  if Borrower or
     Grantor,  as the case may be, after  receiving  written  notice from Lender
     demanding  cure of such default:  (a) cures the default within fifteen (15)
     days; or (b) if the cure requires more than fifteen (15) days,  immediately
     initiates  steps which  Lender  deems in  Lender's  sole  discretion  to be
     sufficient to cure the default and  thereafter  continues and completes all
     reasonable and necessary steps sufficient to produce  compliance as soon as
     reasonably practical.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where
otherwise provided in this Agreement or the Related  Documents,  all commitments
and  obligations of Lender under this Agreement or the Related  Documents or any
other  agreement  immediately  will terminate  (including any obligation to make
Loan  Advances or  disbursements),  and, at Lender's  option,  all  Indebtedness
immediately  will  become due and  payable,  all  without  notice of any kind to
Borrower,  except that in the case of an Event of Default of the type  described
in the "Insolvency"  subsection above, such acceleration  shall be automatic and
not  optional.  In  addition,  Lender  shall have all the  rights  and  remedies
provided in the Related  Documents or available at law, in equity, or otherwise.
Except as may be  prohibited  by  applicable  law,  all of  Lender's  rights and
remedies  shall be cumulative and may be exercised  singularly or  concurrently.
Election by Lender to pursue any remedy  shall not exclude  pursuit of any other
remedy,  and an  election to make  expenditures  or to take action to perform an
obligation  of  Borrower or of any Grantor  shall not affect  Lender's  right to
declare a default and to exercise its rights and remedies.

MISCELLANEOUS  PROVISIONS.  The following miscellaneous provisions are a part of
this Agreement:

     unrelated to Lender. Lender may provide, without any limitation whatsoever,
     to any one or more purchasers, or potential purchasers,  any information or
     knowledge Lender may have about Borrower or about any other matter relating
     to the Loan,  and Borrower  hereby waives any rights to privacy it may have
     with  respect to such  matters.  Borrower  additionally  waives any and all
     notices of sale of participation  interests,  as well as all notices of any
     repurchase of such participation  interests.  Borrower also agrees that the

     Lender or  against  any  purchaser  of such a  participation  interest  and
     unconditionally  agrees that either  Lender or such  purchaser  may enforce

     States mail, first class,  postage prepaid,  addressed to the party to whom
     the notice is to be given at the address shown above.  Any party may change
     its address for  notices  under this  Agreement  by giving  formal  written
     notice to the other parties,  specifying  that the purpose of the notice is
     to change the party's  address.  To the extent permitted by applicable law,
     if there is more than one Borrower,  notice to any Borrower will constitute
     notice to all  Borrowers.  For notice  purposes,  Borrower will keep Lender
     informed at all times of Borrower's current address(es).

     Severability.  If a court of competent  jurisdiction finds any provision of
     this  Agreement  to be  invalid  or  unenforceable  as  to  any  person  or
     circumstance,  such  finding  shall not render  that  provision  invalid or
     unenforceable as to any other persons or  circumstances.  If feasible,  any
     such  offending  provision  shall be deemed to be modified to be within the
     limits of enforceability or validity;  however,  if the offending provision
     cannot be so  modified,  it shall be stricken and all other  provisions  of
     this Agreement in all other respects shall remain valid and enforceable.

     Subsidiaries  and Affiliates of Borrower.  To the extent the context of any
     provisions  of this  Agreement  makes  it  appropriate,  including  without
     limitation any representation, warranty or covenant, the word "Borrower" as
     used herein shall  include all  subsidiaries  and  affiliates  of Borrower.
     Notwithstanding  the foregoing however,  under no circumstances  shall this
     Agreement  be  construed  to  require  Lender  to make  any  Loan or  other
     financial accommodation to any subsidiary or affiliate of Borrower.

     Successors  and Assigns.  All covenants and  agreements  contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure to
     the benefit of Lender,  its  successors  and assigns.  Borrower  shall not,
     however,  have the right to assign its rights  under this  Agreement or any
     interest therein, without the prior written consent of Lender.

     Survival. All warranties,  representations,  and covenants made by Borrower
     in this Agreement or in any  certificate or other  instrument  delivered by
     Borrower to Lender under this  Agreement  shall be  considered to have been
     relied upon by Lender and will  survive the making of the Loan and delivery
     to Lender of the Related Documents, regardless of any investigation made by
     Lender or on Lender's behalf.

     Time Is of the Essence.  Time is of the essence in the  performance of this
     Agreement.

     Waiver.  Lender  shall not be deemed to have  waived any rights  under this
     Agreement  unless such waiver is given in writing and signed by Lender.  No
     delay or  omission  on the part of Lender  in  exercising  any right  shall
     operate as a waiver of such right or any other right. A waiver by Lender of
     a provision of this Agreement shall not prejudice or constitute a waiver of
     Lender's right otherwise to demand strict compliance with that provision or
     any other provision of this Agreement.  No prior waiver by Lender,  nor any
     course of dealing  between  Lender and Borrower,  or between Lender and any
     Grantor,  shall  constitute  a waiver of any of  Lender's  rights or of any
     obligations  of Borrower  or of any Grantor as to any future  transactions.
     Whenever  the  consent  of Lender is  required  under this  Agreement,  the
     granting of such  consent by Lender in any  instance  shall not  constitute
     continuing consent in subsequent  instances where such consent is required,
     and in all cases  such  consent  may be  granted  or  withheld  in the sole
     discretion of Lender.

================================================================================

Principal Amount: $1,500,000.00                Date of Agreement: March 22, 2000


DESCRIPTION OF EXISTING  INDEBTEDNESS.  Promissory  Note dated March 15, 1999 in
the original principal amount of $3,000,000.00, (the "Note").

DESCRIPTION OF COLLATERAL.  Collateral as described in that Commercial  Security
Agreement dated August 17,1998.

DESCRIPTION OF CHANGE IN TERMS. The maturity date of the Note is hereby extended
from April 1, 2000 to July 1, 2000. The credit limit  available  under the terms
of the Note is hereby decreased from $3,000,000.00 to $1,500,000.00.

PROMISE TO PAY. HUMAN PHEROMONE SCIENCES,  INC.  ("Borrower") promises to pay to
Mid-Peninsula Bank ("Lender"), or order, in lawful money of the United States of
America,  the  principal  amount of One Million Five  Hundred  Thousand & 00/100
Dollars ($1,500,000.00) or so much as may be outstanding, together with interest
on the unpaid outstanding  principal balance of each advance.  Interest shall be
calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid interest on July 1, 2000. In addition, Borrower will pay
regular monthly payments of accrued unpaid interest beginning April 1, 2000, and
all  subsequent  interest  payments  are due on the same day of each month after
that.  The annual  interest  rate for this  Agreement  is  computed on a 365/360
basis; that is, by applying the ratio of the annual interest rate over a year of
360 days,  multiplied by the outstanding  principal  balance,  multiplied by the
actual number of days the principal  balance is  outstanding.  Borrower will pay
Lender at  Lender's  address  shown  above or at such other  place as Lender may
designate in writing.  Unless  otherwise  agreed or required by applicable  law,
payments will be applied first to accrued  unpaid  interest,  then to principal,
and any remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to change
from time to time based on changes in an  independent  index  which is the Prime
Rate as published in the Wall Street  Journal  (the  "Index").  The Index is not
necessarily the lowest rate charged by Lender on its loans, If the Index becomes
unavailable  during the term of this loan,  Lender may  designate  a  substitute
index after notice to Borrower. Lender will tell Borrower the current Index rate
upon Borrower's request.  Borrower  understands that Lender may make loans based
on other rates as well.  The interest rate change will not occur more often than
each day. The Index currently is 8.750%.  The interest rate to be applied to the
unpaid principal balance of this Agreement will be at a rate of 1.000 percentage
point over the Index,  resulting in an initial rate of 9.750%.  NOTICE: Under no
circumstances  will the interest rate on this Agreement be more than the maximum
rate allowed by applicable law.

PREPAYMENT;  MINIMUM  INTEREST  CHARGE.  Borrower  agrees that all loan fees and
other  prepaid  finance  charges are earned fully as of the date of the loan and
will not be subject to refund  upon early  payment  (whether  voluntary  or as a
result of default), except as otherwise required by law. In any event, even upon
full prepayment of this Agreement,  Borrower understands that Lender is entitled
to a minimum interest charge of $250.00. Other than Borrower's obligation to pay
any minimum interest  charge,  Borrower may pay without penalty all or a portion
of the amount owed  earlier  than it is due.  Early  payments  will not,  unless
agreed to by Lender in writing,  relieve  Borrower of  Borrower's  obligation to
continue to make payments of accrued unpaid interest.  Rather,  they will reduce
the principal balance due.

LATE  CHARGE.  If a payment  is 10 days or more late,  Borrower  will be charged
5.000% of the unpaid portion of the regularly scheduled payment.

DEFAULT.  Borrower  will be in  default  if any of the  following  happens:  (a)
Borrower  fails to make any payment when due.  (b)  Borrower  breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any  other  term,  obligation,  covenant,  or  condition  contained  in this
Agreement or any agreement related to this Agreement,  or in any other agreement
or loan  Borrower  has with  Lender.  (c)  Borrower  defaults  under  any  loan,
extension of credit,  security  agreement,  purchase or sales agreement,  or any
other  agreement,  in favor of any other  creditor or person that may materially
affect any of Borrower's  property or  Borrower's  ability to repay this Note or
perform Borrower's  obligations under this Note or any of the Related Documents.
(d) Any  representation  or statement made or furnished to Lender by Borrower or
on Borrower's  behalf is false or misleading in any material  respect either now
or at the time made or furnished.  (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property,  Borrower makes an assignment for
the benefit of creditors,  or any proceeding is commenced  either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's  property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any  guarantor  dies or any of the other  events  described  in this default
section occurs with respect to any guarantor of this  Agreement.  (h) A material
adverse change occurs in Borrower's financial condition,  or Lender believes the
prospect of payment or performance of the Indebtedness is impaired.

If any default,  other than a default in payment, is curable and if Borrower has
not been  given a notice of a breach  of the same  provision  of this  Agreement
within  the  preceding  twelve  (12)  months,  it may be cured  (and no event of
default will have  occurred) if Borrower,  after  receiving  written notice from
Lender demanding cure of such default: (a) cures the default within fifteen (15)
days;  or (b) if the cure  requires  more than  fifteen  (15) days,  immediately
initiates  steps which Lender deems in Lender's sole discretion to be sufficient
to cure the default and  thereafter  continues and completes all  reasonable and
necessary  steps  sufficient  to  produce   compliance  as  soon  as  reasonably
practical.

LENDER'S  RIGHTS.  Upon default,  Lender may declare the entire unpaid principal
balance on this  Agreement  and all accrued  unpaid  interest  immediately  due,
without notice, and then Borrower will pay that amount.  Upon Borrower's failure
to pay all amounts declared due pursuant to this section,  including  failure to
pay upon final  maturity,  Lender,  at its option,  may also, if permitted under
applicable law,  increase the variable  interest rate on this Agreement to 6.000
percentage  points over the Index.  Lender may hire or pay someone  else to help
collect this  Agreement if Borrower does not pay.  Borrower also will pay Lender
that amount. This includes, subject to any limits under applicable law, Lender's
attorneys'  fees and Lender's legal expenses  whether or not there is a lawsuit,
including  attorneys'  fees  and  legal  expenses  for  bankruptcy   proceedings
(including  efforts  to modify  or vacate  any  automatic  stay or  injunction),
appeals, and any anticipated  post-judgment  collection services.  Borrower also
will pay any court costs,  in addition to all other sums  provided by law.  This
Agreement  has been  delivered  to Lender and accepted by Lender in the State of
California.  If there is a lawsuit,  Borrower  agrees upon  Lender's  request to
submit to the  jurisdiction  of the courts of Santa Clara  County,  the State of
California. This Agreement shall be governed by and construed in accordance with
the laws of the State of California.

LINE OF CREDIT.  This Agreement  evidences a revolving line of credit.  Advances
under this Agreement may be requested either orally or in writing by Borrower or
by an  authorized  person.  Lender  may,  but need  not,  require  that all oral
requests  be  confirmed  in  writing.  All  communications,   instructions,   or
directions  by  telephone  or otherwise to Lender are to be directed to Lender's
office shown above. The following party or parties are

authorized to request  advances  under the line of credit until Lender  receives
from Borrower at Lender's  address  shown above written  notice of revocation of
their authority:  William P. Horgan, Chief Executive Officer; and Greg Fredrick.
Borrower  agrees to be liable for all sums either:  (a)  advanced in  accordance
with  the  instructions  of an  authorized  person  or  (b)  credited  to any of
Borrower's  accounts  with Lender.  The unpaid  principal  balance owing on this
Agreement at any time may be evidenced by  endorsements  on this Agreement or by
Lender's internal records, including daily computer printouts.  Lender will have
no  obligation  to advance  funds under this  Agreement  if: (a) Borrower or any
guarantor is in default under the terms of this  Agreement or any agreement that
Borrower or any  guarantor  has with Lender,  including  any  agreement  made in
connection  with the signing of this  Agreement;  (b) Borrower or any  guarantor
ceases  doing  business or is  insolvent;  (c) any  guarantor  seeks,  claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of this
Agreement  or any other loan with  Lender;  or (d)  Borrower  has applied  funds
provided  pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of
the original  obligation or obligations,  including all agreements  evidenced or
securing  the  obligation(s),  remain  unchanged  and in full force and  effect.
Consent  by Lender to this  Agreement  does not waive  Lender's  right to strict
performance of the  obligation(s)  as changed,  nor obligate  Lender to make any
future change in terms. Nothing in this Agreement will constitute a satisfaction
of the obligation(s).  It is the intention of Lender to retain as liable parties
all makers and endorsers of the original obligation(s),  including accommodation
parties, unless a party is expressly released by Lender in writing. Any maker or
endorser, including accommodation makers, will not be released by virtue of this
Agreement.  If any person who signed the original  obligation does not sign this
Agreement below,  then all persons signing below acknowledge that this Agreement
is  given  conditionally,  based  on  the  representation  to  Lender  that  the
non-signing  party  consents to the changes and  provisions of this Agreement or
otherwise  will not be  released  by it.  This  waiver  applies  not only to any
initial  extension,  modification  or release,  but also to all such  subsequent
actions.

MISCELLANEOUS PROVISIONS.  Lender may delay or forgo enforcing any of its rights
or remedies  under this Agreement  without  losing them.  Borrower and any other
person who signs,  guarantees or endorses this Agreement,  to the extent allowed
by law, waive any applicable  statute of  limitations,  presentment,  demand for
payment,  protest and notice of  dishonor.  Upon any change in the terms of this
Agreement,  and unless otherwise expressly stated in writing, no party who signs
this Agreement,  whether as maker,  guarantor,  accommodation maker or endorser,
shall be released from  liability.  All such parties agree that Lender may renew
or extend  (repeatedly  and for any length of time) this  loan,  or release  any
party or guarantor  or  collateral;  or impair,  fail to realize upon or perfect
Lender's security  interest in the collateral;  and take any other action deemed
necessary by Lender without the consent of or notice to anyone. All such parties
also agree that Lender may modify this loan  without the consent of or notice to
anyone other than the party with whom the modification is made.

PRIOR TO SIGNING THIS AGREEMENT, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS
OF THIS AGREEMENT,  INCLUDING THE VARIABLE  INTEREST RATE  PROVISIONS.  BORROWER
AGREES TO THE TERMS OF THE  AGREEMENT  AND  ACKNOWLEDGES  RECEIPT OF A COMPLETED
COPY OF THE AGREEMENT.
