                                  PART I

Item 1. Business

    NeoRx   Corporation   ("NeoRx"  or  the   "Company")   develops   innovative
biopharmaceuticals  for the diagnosis and treatment of cancer and cardiovascular
disease.  As part  of its  cancer  treatment  program,  NeoRx  is  developing  a
proprietary  pretargeting  platform  for  the  delivery  of  therapeutic  agents
directly to tumor sites.

    The Company's portfolio of products include  VERLUMA(TM),  a small cell lung
cancer imaging kit, that was cleared for marketing by the United States Food and
Drug Administration (the "FDA") in August 1996. The Company's AVICIDIN(R) cancer
therapy  agent is currently in Phase I/II  clinical  trials for the treatment of
solid  tumors.   Phase  I  patient  accrual  for  the  BIOSTENT(R)   product,  a
pharmaceutical agent designed to reduce restenosis following balloon angioplasty
through the inhibition of vascular remodeling, was completed in 1996 and data on
the final  patients to complete  the six month  follow-up  are being  collected.
NeoRx is also conducting  investigations into atherosclerosis in a Phase I study
to  determine  safety  and dosage of a  pharmaceutical  agent with the intent of
inhibiting atherosclerosis.

Cancer and Its Treatment

    Cancer is second only to  cardiovascular  disease as a cause of death in the
United  States.   The  American  Cancer  Society  estimates  that  approximately
1,382,000 new cases of cancer will be diagnosed in the United States in 1997, of
which 60% are  expected to be tumors of the lung,  colon,  breast and  prostate.
Cancer  is  a  large  group  of  diseases   characterized  by  uncontrolled  and
proliferative cell division. Cancer cells have the tendency to dislodge from the
sites where the tumors  originate and  metastasize  (spread from one part of the
body to another).

    Current   regimens  for  the  treatment  of  cancer  include   chemotherapy,
external-beam  radiation and surgical intervention.  Generally,  existing cancer
therapy  for   high-incidence   tumors  such  as  lung,   colon  and  breast  is
characterized  by  both  relatively  low  efficacy  and  considerable  toxicity.
Chemotherapy drugs are generally administered intravenously so that the drug can
circulate  throughout the body. With rare  exceptions,  chemotherapy is the only
available  treatment  for tumors that have spread  throughout  the body,  but it
provides only modest  benefits for patients with the most  frequently  occurring
malignancies,  such as lung,  colon or  breast  cancer.  As  chemotherapy  drugs
circulate  throughout  the body,  they kill cancer cells,  but are also toxic to
normal cells. Consequently,  cancer patients receiving chemotherapy often suffer
severe,  sometimes  life-  threatening,  side  effects,  such as  damage to bone
marrow,  lungs,  heart,  kidneys and nerves.  The optimal  drug dose for killing
cancer cells must therefore often be reduced to avoid intolerable toxicities.
    Pretargeting:   NeoRx's  Approach  to  Delivering   Drugs.   NeoRx's  cancer
therapeutic   product  under  development   employ  monoclonal   antibody  based
technology. Antibodies are proteins produced by certain white blood cells in the
body's  immune  system in  response  to antigens  (foreign  substances)  such as

                                       1
<PAGE>
                                         
viruses,  bacteria,  toxins and specific types of cancer cells. An antibody will
recognize and bind specifically only to a single type of antigen.  This quality,
known as "specificity," makes antibodies  potentially useful for the delivery of
imaging and therapeutic agents to disease sites.

    Monoclonal  antibodies  are  laboratory-produced  and share the  ability  of
natural human antibodies to bind to one particular  antigen target. In 1975, the
first practical method was demonstrated for producing  monoclonal  antibodies in
significant  quantities.  This method  consists of obtaining  antibody-producing
cells from mice immunized against a selected antigen and fusing these cells with
a type of cell that reproduces indefinitely. The products of the fusion of these
two  types of cells are  called  hybridomas.  Hybridomas  secrete  the  specific
antibody desired, grow well in culture and multiply to generate a vast number of
duplicate  hybridomas that also secrete the desired  antibody.  These antibodies
can be purified for use as pharmaceutical agents.

    In the conventional approach to radioimmunotherapy ("RIT"), the radiation is
linked to the antibody that is then  administered to patients.  The antibody and
the radiation circulate  together.  NeoRx's  pretargeting  technology employs an
antibody-mediated  targeting  strategy that is designed to deliver high doses of
an active  agent to tumor  cells,  while  minimizing  toxicity to normal  tissue
associated with conventional therapy.

    AVICIDIN:  The  First  NeoRx  Agent to Use the  Pretargeting  Platform.  The
AVICIDIN  agent takes  advantage of the high binding  affinity of two molecules:
biotin and  streptavidin.  An antibody linked to streptavidin is administered to
the patient and allowed to  accumulate  on the surface of the tumor cells.  This
accumulation  occurs because the antibody  portion of the  antibody-streptavidin
conjugate  recognizes and binds to antigen markers on the tumor cell surface. In
animal  experiments,  the conjugate attains peak uptake in the tumor after 24-36
hours,  at which time a clearing  agent is  administered  to remove  circulating
conjugate from the  bloodstream.  The final step involves  administering  biotin
linked  to  the  therapeutic  radionuclide,   yttrium-90.  This  small  molecule
biotin-yttrium   complex  is  designed  to  bind   specifically   to  where  the
streptavidin has accumulated, with the resultant beta particle emission from the
yttrium-90  killing  tumor  cells.  Biotin-yttrium  that  does  not  bind to the
streptavidin is quickly  eliminated  through the kidneys,  thereby  reducing the
radiation  dose to the bone  marrow.  In  preclinical  studies in  animals,  the
AVICIDIN agent  achieved a tenfold  improvement in the therapy ratio compared to
conventional   RIT,   accompanied   by   durable,    complete   regressions   of
chemotherapy-resistant  human  lung,  breast  and colon  cancer  tumors in mice.
Results of preclinical  studies are not  necessarily  indicative of results that
will be attained in human clinical trials.

    The AVICIDIN agent is being tested in Phase I/II clinical trials in patients
with tumors  that bind with the  antibody,  such as cancers of the lung,  colon,
breast and  prostate.  The  purposes of the study are to  determine  the maximum
tolerated  dose ("MTD") of  radiation,  to observe  anti-tumor  effects,  and to
determine the optimal timing and dosing of each component.

    In one series of tests, the Company's  investigators  are trying to optimize
the dosing and timing of the three components ("dosimetry").  In a second series
of tests,  the  investigators  are raising the radiation dose in groups of three
patients to determine the MTD and to observe anti-tumor effects when they occur.
These studies use an antibody  produced by mouse cells so that the antibody is a
murine  protein and results in a human  anti-mouse  antibody  ("HAMA")  response
after the first dose. Once the Company is satisfied it has a suitable  humanized
antibody, it plans to substitute this for the foreign murine antibody.

    To date,  the  AVICIDIN  dosimetry  studies  have shown  substantially  less
exposure  of  bone  marrow  than  conventional  RIT.  This  has  permitted  safe
administration  of higher radiation doses, and tumor shrinkage has been observed
following  just a single  AVICIDIN  dose even in patients with  advanced,  bulky
tumors.

    Other Uses of  Pretargeting.  NeoRx is testing the  delivery  of  additional
agents such as other forms of radiation,  drugs, immune response modifiers (e.g.

                                       2
<PAGE>
 
tumor necrosis  factor).  This unique  pretargeting  platform may also offer the
first  real  opportunity  to  deliver  alpha  emitters,   a  form  of  radiation
significantly  more  potent  than  yttrium-90,  effectively  and safely to solid
tumors.  NeoRx has received a Small Business  Innovative Research ("SBIR") grant
to study alpha emitter chemistry.

    Cancer:  Diagnosis  and  Staging of  Disease.  Early  diagnosis  and precise
detection of the malignant  cells are important  for cancer  treatment.  Current
diagnostic imaging techniques  include x-rays,  computerized  tomography ("CT"),
ultrasonography,  radioisotopic  imaging and nuclear magnetic  resonance imaging
("MRI"). Once cancer is suspected, its presence must be confirmed by biopsy (the
examination of cells removed from the body).  The next step is to use diagnostic
imaging to "stage" the patient,  that is, to determine the extent of the disease
throughout  the body.  Accurate  staging is important for designing  appropriate
treatment.  Using current methods,  several diagnostic imaging procedures may be
required to determine the organs to which the cancer has spread.  Staging may be
inaccurate  if all possible  body sites are not examined or if tumor  metastases
are too small to be detected by the diagnostic procedure used.

    Small Cell Lung Cancer:  Diagnosis and Staging.  The American Cancer Society
estimates that approximately  178,000 new cases of lung cancer will occur in the
United States in 1997, of which the Company believes  approximately  47,000 will
be small cell lung cancer.  Symptoms of this disease  usually  appear only after
the  disease  has  advanced  beyond the stage when it may be  surgically  cured.
According to the American Cancer Society,  the five-year  survival rate for lung
cancer  is 13%.  Although  most  small  cell lung  cancer  patients  respond  to
chemotherapy,  most also suffer a relapse.  Current treatment of this disease is
based on the  extent to which the tumor has  spread  throughout  the body.  As a
result, accurate imaging to determine the extent of the disease is important for
designing  appropriate   treatment.   Patients  whose  disease  has  not  spread
extensively are generally treated with chemotherapy and externally applied chest
radiation.  Those  patients whose disease has spread to the point that radiation
treatment  would not encompass  all known tumors  within one radiation  port are
treated with chemotherapy only.

    The  degree  to which  small  cell  lung  cancer  has  spread  is  generally
determined using a standard battery of four imaging tests, including CT scans of
the head,  chest and abdomen and a bone scan. This standard battery of tests may
take up to one week.  Bone marrow  aspirate,  a procedure in which a bone marrow
sample is removed for examination, is occasionally used as an additional test.

    The VERLUMA Kit: Imaging for Small Cell Lung Cancer.  The VERLUMA kit is the
Company's  diagnostic  imaging  product that is  indicated  to detect  extensive
disease in patients with biopsy-confirmed,  previously untreated small cell lung
cancer.  Boehringer Ingelheim International GmbH ("Boehringer  Ingelheim") holds
world-wide  manufacturing  rights and non-North American marketing rights to the
VERLUMA  kit.  Boehringer  Ingelheim  will pay  royalties  to  NeoRx  on  future
non-North American product sales, if any.

    The DuPont Merck Pharmaceutical Company ("DuPont Merck") markets the VERLUMA
kit in the United States and holds exclusive North American rights to market the
VERLUMA kit. In addition to paying  NeoRx $4.5  million  upon the FDA  marketing
clearance in the United States,  DuPont Merck will pay NeoRx  royalties on sales
of the VERLUMA Kit in North  America.  To date, the VERLUMA kit is approved only
in the United States. No applications for foreign approvals have been filed.

    The VERLUMA kit employs a Fab fragment of an antibody,  designated NR-LU-10,
linked to a nontoxic dose of the gamma-emitting radionuclide technetium-99m that
is injected intravenously and allowed to concentrate at the tumor sites. A gamma
camera is then used to  determine  the  location of the tumors.  In a Phase I/II
clinical  trial,  the VERLUMA kit localized to primary and/or  metastatic  small
cell and non-small  cell lung cancer,  and breast,  colon and prostate  cancers.
Data from a  completely  blinded  analysis of NeoRx's  Phase III small cell lung
cancer  clinical  trial show that the  VERLUMA  kit is more  sensitive  than any
single test used in the standard  battery of four tests to determine how far the

                                       3
<PAGE>
 
tumor has spread and has an accuracy level comparable to the standard battery of
tests. The Company believes that its use may result in cost savings,  as well as
reduced staging time compared to conventional tests.

Cardiovascular Disease and Its Treatment

    The American  Heart  Association  estimates  that  approximately  60 million
Americans have one or more types of cardiovascular disease, and that the cost of
cardiovascular  diseases  and  stroke in 1997 will be $259  billion.  Nearly one
million  people die of  cardiovascular  disease each year in the United  States,
making it the leading cause of death.

    Cardiovascular  disease is  divided  into four main  categories:  high blood
pressure,  coronary heart disease,  stroke and rheumatic heart disease.  Medical
procedures to treat coronary  heart disease  include  percutaneous  transluminal
coronary angioplasty, coronary artery bypass surgery and heart transplantation.

     Angioplasty:  The  Procedure.  Angioplasty  is a medical  procedure used to
increase blood flow through coronary  arteries that have been partially  blocked
by the build-up of plaque on the interior of the arterial wall.

    Restenosis is the recurrent  narrowing of an artery  following  angioplasty.
This  narrowing,  that reduces blood flow through the artery,  is believed to be
caused by a combination of at least three distinct but interrelated factors: (1)
vascular  remodeling,  or chronic  constriction  of the  artery,  (2) blood clot
formation and (3) the migration and  proliferation of smooth muscle cells at the
site of the  angioplasty  procedure  that encroach upon the flow of blood.  Data
from human studies suggests that vascular  remodeling  accounts for the majority
of late lumen loss that leads to restenosis following balloon angioplasty.

    The Company believes that over 500,000  angioplasties  were performed in the
United  States  in  1996,  and  that  approximately  30% of such  patients  will
experience restenosis following the angioplasty procedure. If restenosis occurs,
it may necessitate open heart surgery (coronary artery bypass graft),  sometimes
on an emergency basis, or additional coronary  angioplasty  procedures,  such as
repeat angioplasty and/or the placement of a metal stent in the artery.

    BIOSTENT:  NeoRx's Approach to Treating  Restenosis.  The Company's BIOSTENT
agent under  development is designed to inhibit  vascular  remodeling  following
balloon  angioplasty.  By  addressing  remodeling,  the  BIOSTENT  agent  may be
complementary  to  the  anti-thrombotics   currently  on  the  market  or  under
development  by other  companies  for the treatment of  restenosis.  The drug is
intended to be  delivered  locally  immediately  following  angioplasty  using a
delivery  catheter.  The Company  believes that this method delivers the drug to
the  angioplasty  site and reduces  the chances of toxicity  that might occur if
systemic treatment were used to deliver similar concentrations at the site.

     NeoRx's  preclinical  studies  have shown that  administering  the BIOSTENT
agent immediately after angioplasty  inhibits chronic construction of the artery
wall and thus helps  maintain  its  dilated  position.  As a normal  response to
injury caused by  angioplasty,  the muscle cells in the ballooned  arterial wall
secrete a biological "cement" called collagen, a supportive protein of the body.
The  Company   believes  that  the  collagen  forms  a  rigid  matrix,   thereby
biologically  supporting or "stenting"  the arterial wall during the period that
treatment with the BIOSTENT agent inhibits arterial constriction.

    The BIOSTENT agent may be unique with respect to other pharmaceutical agents
that have been  evaluated  in  animal  models  and  reported  in the  scientific
literature in that it not only inhibits  restenosis,  but actually  sustains the
increase in the luminal area following balloon trauma compared to the ballooned,
but  untreated,  arteries.  NeoRx  scientists  have  assessed the effects of the
BIOSTENT treatment method in a swine femoral artery model that was then extended
to swine coronary  arteries.  Analysis of swine femoral  arteries for as long as

                                       4
<PAGE>

eight weeks and of swine coronary  arteries for as long as three weeks following
a single exposure to the BIOSTENT agent has indicated in these  experiments that
the treatment sustains the increase in the luminal area following balloon trauma
compared to the ballooned, but untreated, arteries.

    The BIOSTENT treatment method consists of the cytoskeletal inhibiting agent,
cytochalasin B, delivered through a specialized intracoronary delivery catheter.
The catheter is an  over-the-wire  design that allows rapid  placement using the
same  guidewire  used for balloon  dilation.  Commercialization  of the BIOSTENT
agent will depend on obtaining the FDA approval of the catheter. NeoRx completed
patient accrual of a multidose, multicenter, randomized,  double-blinded Phase I
trial. An interim analysis of the majority of the patients  revealed no evidence
of  drug-related  toxicity.  A final  analysis  of the  data  for the six  month
follow-up is being performed.

    Atherosclerosis.  Atherosclerosis  is a  complex  disease  of blood  vessels
commonly  understood as clogging of arteries with  cholesterol.  It is a leading
cause of deaths from heart  attack and stroke.  Clogged  arteries do not deliver
oxygen-carrying  blood to organs as well as normal  arteries and are more likely
to become  completely  restricted with blood clots that shut off blood flow. The
result is the affected organ receives insufficient oxygen and may die if flow is
not restored  rapidly,  leading to  conditions  such as heart attack and stroke.
Surgery  and/or  angioplasty  (as described  above) can improve blood flow,  but
prevention or reduction in the disease progression would be preferred.

    Raising  TGF(beta)  Levels:  NeoRx's  Approach to Treating  Atherosclerosis.
Scientists at the University of Cambridge in the United  Kingdom  ("Cambridge"),
working with NeoRx,  have discovered that patients with advanced coronary artery
disease have low levels of active TGF(beta), a protein that regulates the growth
of certain cell types such as those found in the lining of  arteries.  They have
reported that segments of arteries  prone to  atherosclerosis  are low in active
TGF(beta) and that the elevation of active TGF(beta) can prevent the development
of lesions in arteries of a mouse  animal  model that  express the human  apo(a)
associated with atherosclerosis lesions in humans.

    A Phase I dosing study is being  conducted to determine  safety and the dose
of a drug that maximally increases activated TGF(beta) in patients with advanced
coronary artery disease. This drug has been provisionally  licensed from a third
party.  Either  NeoRx or the  third  party  may  terminate  at will the  further
development of this drug.

Patents and Proprietary Rights

    The Company's policy is to protect its proprietary technology  aggressively.
In addition to filing patent  applications  in the United States for many of its
inventions,  the Company files patent  applications  in Canada,  major  European
countries,  Japan and  additional  foreign  countries  on a  selective  basis to
protect important inventions.

    The Company holds a co-exclusive license for the monoclonal antibody used in
its cancer imaging and treatment products and also has obtained U.S. and foreign
patent  protection  relating  to  its  cancer  imaging  products.  NeoRx  has an
exclusive  license from  Stanford  University  for a patent  issued in the U.S.,
Europe  and Japan  that  covers  the  pretargeting  technology  used in  NeoRx's
AVICIDIN cancer therapy product under development.  The Company has been awarded
additional  U.S.  patents  pertaining to its  pretargeting  technology,  and has
received notices of allowance in the U.S. on several others;  other applications
are pending. The Company has also received a notice of allowance in the U.S. for
its BIOSTENT technology and has several patent applications  pending in both the
U.S. and foreign  jurisdictions.  NeoRx has  exclusively  licensed  from Indiana
University  a patent  covering  catheter  delivery  into blood  vessel  walls of
sustained release therapeutic agents contained within a particulate dosage form.
NeoRx is the exclusive  assignee of a two U.S.  patents granted to its Cambridge
collaborators  for the use of  various  TGF(beta)  elevating  agents  to treat a
variety of cardiovascular  indications and has additional  pending  applications
related to this technology.

    Competitors have filed  applications  for, or have been issued,  patents and
may obtain  additional  patents and  proprietary  rights relating to products or
processes  competitive  with or relating to those of the Company.  The scope and
validity  of these  patents,  the extent to which the Company may be required to
obtain licenses  thereunder or under other proprietary  rights, and the cost and
availability  of licenses  are unknown.  Accordingly,  there can be no assurance
that the Company's patent  applications will result in additional  patents being
issued  or  that,  if  issued,   the  patents  will  afford  protection  against
competitors  with similar  technology,  nor can there be any assurance  that any
patents issued to the Company will not be infringed or designed around by others
or that others will not obtain patents that the Company would need to license or
design around.

     As part of NeoRx's ongoing research activities, the Company in the ordinary
course  seeks  assurances  that it will own or license  any  rights  that may be
necessary  or useful to its  business.  The  Company  believes  that in  certain
circumstances  licensing  or  cross-licensing  arrangements  pertaining  to  the
relevant  technologies  and  providing  reasonable  economic  terms  may  be  an
expedient  way  to  resolve  any  potential   infringement   issues.   In  other
circumstances,   such  arrangements  may  not  be  warranted  or  obtainable  on
commercially  reasonable terms. In the event it were determined that one or more
of the  Company's  products  infringe one or more of such  patents,  the Company
could seek to enter a licensing or cross-licensing arrangement, but there can be
no assurance that such an arrangement would be available or, if available,  that
the terms of such an arrangement would be reasonable.

Competition

    Research and  development  in cancer and  cardiovascular  diseases is highly
competitive.  NeoRx faces  competition  from emerging  companies and established
biotechnology,  pharmaceutical and chemical  companies.  Many emerging companies
have corporate  partnership  arrangements with large,  established  companies to
support research, development and commercialization efforts of products that may
be competitive with those being developed by the Company. In addition,  a number
of established  pharmaceutical and chemical companies are developing proprietary
technologies or have enhanced their  capabilities by entering into  arrangements
with,  or  acquiring,   companies  with  proprietary  monoclonal  antibody-based
technology  or other  technologies  applicable  to the imaging or  treatment  of
cancer, the prevention of restenosis or the treatment of  atherosclerosis.  Many

                                       6
<PAGE>

of the  Company's  existing  or  potential  competitors  have or have  access to
substantially  greater  financial,  research  and  development,   marketing  and
production resources than those of the Company.

    Other companies may develop and introduce products and processes competitive
with or superior to those of the Company.  Further, the development by others of
new cancer diagnostic or treatment  products,  anti- restenosis  products or any
cancer  or  atherosclerosis  prevention  products  could  render  the  Company's
technology and products under  development  less  competitive,  uneconomical  or
obsolete.

    Timing of market  introduction and health care reform,  both  uncertainties,
will affect the  competitive  position of the  Company's  products.  The Company
believes that competition among products approved for sale will be based,  among
other things, on product safety, efficacy, reliability,  availability, price and
patent position.

    Other  companies are  developing  antibody-based  cancer  imaging  products.
Conventional  radiography,  conventional nuclear medicine scanning (including an
indium-labeled peptide for neuroendocrine tumors), CT and MRI are already widely
available and used by a large number of physicians.  These, along with a nuclear
medicine test now being marketed,  constitute the current competition for use of
the Company's VERLUMA lung cancer imaging product.

    The Company's cancer therapy products under development are designed for the
treatment of metastatic  cancer or where there is a very high  statistical  risk
that  the  cancer  has  spread.  The  Company  anticipates  that  the  principal
competition   in  this  type  of  cancer   treatment  will  come  from  existing
chemotherapy,  hormone  therapy and  biological  therapies  that are designed to
treat the same cancer stage. Many  pharmaceutical,  emerging  pharmaceutical and
biotechnology  companies  are  testing  a  large  array  of  alternative  cancer
treatments. If any of these proves to be more effective, safer or less expensive
than  the  Company's  products  under  development,  the  Company's  competitive
position could be adversely affected.

    The  Company's  anti-restenosis  product  under  development  is designed to
prevent  restenosis of blood vessels following  angioplasty where such narrowing
is  due  to  vascular   remodeling.   Due  to  the  incidence  and  severity  of
cardiovascular  diseases,  the market for therapeutic products that address such
diseases is large, and competition is intense and expected to increase. There is
no obligation for the licensor of the drug being studied for TGF upregulation to
permit its continued development after the dosing study is completed.

Government Regulation and Product Testing

    The  manufacture  and marketing of the Company's  proposed  products and its
research  and  development  activities  are  subject to  regulation  for safety,
efficacy and quality by numerous  government  authorities  in the U.S. and other
countries.  In the U.S., drugs and biologics are subject to rigorous  regulation
by the FDA. The Federal Food, Drug and Cosmetic Act of 1976, as amended, and the
regulations  promulgated  thereunder,  and other federal and state  statutes and
regulations  govern,  among other  things,  the  testing,  manufacture,  safety,
efficacy, labeling, storage, record keeping, approval, advertising and promotion
of  the  Company's  products.  Product  development  and  approval  within  this
regulatory  framework  take a number  of years to  accomplish  and  involve  the
expenditure of substantial resources.

    The steps required before a pharmaceutical agent may be marketed in the U.S.
include  (i)  preclinical  laboratory  tests,  in vivo  preclinical  studies and
formulation  studies,  (ii) the submission to the FDA of an Investigational  New
Drug  Application  ("IND"),  which must become  effective  before human clinical
trials can commence, (iii) adequate and well-controlled human clinical trials to
establish the safety and efficacy of the drug, (iv) the submission of a Biologic
License  Application ("BLA") or New Drug Application ("NDA") to the FDA, and (v)
the FDA approval of the BLA or NDA prior to any  commercial  sale or shipment of
the drug. In addition to obtaining FDA approval for each product,  each domestic

                                       7
<PAGE>

drug manufacturing  establishment must be registered with, and inspected by, the
FDA. Domestic  manufacturing  establishments are subject to biennial inspections
by the FDA and must comply with current  Good  Manufacturing  Practice  ("cGMP")
regulations  enforced by the FDA through its facilities  inspection  program for
biologics,  drugs and devices.  To supply products for use in the U.S.,  foreign
manufacturing  establishments  must comply with cGMP and are subject to periodic
inspection by the FDA or by corresponding  regulatory agencies in such countries
under reciprocal agreements with the FDA.

    Preclinical  studies include laboratory  evaluation of product chemistry and
formulation,  as well as animal  studies,  to assess  the  potential  safety and
efficacy  of  the  product.  Preclinical  safety  tests  must  be  conducted  by
laboratories  that comply with the FDA  regulations  regarding  Good  Laboratory
Practice.  The results of the  preclinical  studies are  submitted to the FDA as
part of an IND and are  reviewed  by the FDA  prior  to  commencement  of  human
clinical trials. Unless the FDA provides comments to an IND, the IND will become
effective 30 days  following  its receipt by the FDA.  There can be no assurance
that  submission  of an IND will  result in the FDA  authorization  to  commence
clinical trials.

    Clinical trials involve the administration of the  investigational  new drug
to healthy  volunteers  or to  patients  under the  supervision  of a  qualified
principal  investigator.  Clinical  trials are conducted in accordance  with the
FDA's Protection of Human Subjects regulations and Good Clinical Practices under
protocols that detail the objectives of the study,  the parameters to be used to
monitor safety and the efficacy criteria to be evaluated.  Each protocol must be
submitted to the FDA as part of the IND.  Further,  each clinical  study must be
conducted  under the  auspices  of an  independent  Institutional  Review  Board
("IRB") at the  institution  at which the study will be conducted.  The IRB will
consider,  among other things, ethical factors, the safety of human subjects and
the possible liability of the institution.

     Clinical trials are typically conducted in three sequential phases, but the
phases may overlap. In Phase I, the drug is tested for safety (adverse effects),
dosage  tolerance,  metabolism,  distribution,  excretion  and  pharmacodynamics
(clinical  pharmacology).  Phase  II  involves  studies  in  a  limited  patient
population  to (i)  determine  the efficacy of the drug for  specific,  targeted
indications,  (ii)  determine  dosage  tolerance and optimal  dosage,  and (iii)
identify  possible adverse effects and safety risks. When a compound is found to
have  potential  efficacy and to have an acceptable  safety  profile in Phase II
clinical  trials,  Phase III clinical trials are undertaken to further  evaluate
clinical  efficacy  and to further  test for safety  within an expanded  patient
population at  geographically  dispersed  clinical study sites.  There can be no
assurance that Phase I, Phase II or Phase III clinical  trials will be completed
successfully  within any specific time period, if at all, with respect to any of
the Company's products subject to such trials.  Furthermore,  the Company or the
FDA may  suspend  clinical  trials  at any  time if it is  determined  that  the
subjects or patients are being exposed to an unacceptable health risk.

    The  results of the  pharmaceutical  development,  preclinical  studies  and
clinical  trials  are  submitted  to the  FDA in the  form  of a BLA or NDA  for
approval of the marketing and  commercial  shipment of the drug. The testing and
approval  processes are likely to require  substantial time and effort and there
can be no assurance  that any approval will be granted on a timely basis,  if at
all.  The FDA may deny a BLA or NDA if  applicable  regulatory  criteria are not
satisfied,  may  require  additional  testing  or  information,  or may  require
postmarketing  testing and  surveillance  to monitor the safety of the Company's
products if it does not view the BLA or NDA as containing  adequate  evidence of
the safety and efficacy of the drug.

    Notwithstanding  the submission of such data, the FDA may ultimately  decide
that the  application  does not satisfy its  regulatory  criteria for  approval.
Moreover,  if regulatory approval of a drug is granted, such approval may entail
limitations on the indicated uses for which it may be marketed. Finally, product
approvals  may be  withdrawn  if  compliance  with  regulatory  standards is not
maintained or if problems occur following initial marketing.

                                       8
<PAGE>


    Among the  conditions  for BLA or NDA approval is the  requirement  that the
prospective  manufacturers' quality control and manufacturing procedures conform
to  cGMP.  In  complying  with   standards  set  forth  in  these   regulations,
manufacturers  must  continue to expend  time,  money and effort in the areas of
production and quality control to ensure full technical compliance.

    In addition to regulations  enforced by the FDA, the Company also is subject
to  regulations  under  occupational  safety  and  health  laws,   environmental
protection laws and other present and potential  future federal,  state or local
regulations.  The Company's research and development involves the controlled use
of hazardous materials,  chemicals, and various radioactive compounds.  Although
the Company  believes that its safety  procedures  for handling and disposing of
such  materials  comply  with the  standards  prescribed  by state  and  federal
regulations, the risk of accidental contamination or injury from these materials
cannot be completely  eliminated.  In the event of such an accident, the Company
could be held liable for any damages  that result and any such  liability  could
exceed the  Company's  resources.  In addition,  federal and state  agencies and
congressional  committees  have  expressed  interest  in further  regulation  of
biotechnology.  The  Company  is unable to  estimate  the  extent  and impact of
regulation in the biotechnology  field resulting from any future federal,  state
or local legislation or administrative action.

    For clinical  investigation  and marketing  outside the United  States,  the
Company or its  collaborative  partners  also are subject to foreign  regulatory
requirements  governing human clinical trials and marketing  approval for drugs.
The requirements  governing the conduct of clinical trials,  product  licensing,
pricing and  reimbursement  vary widely for European  countries  both within and
outside the European Community.

Important Factors Regarding Forward-Looking Statements

    The following  important  factors,  among others,  could cause the Company's
actual  results to differ  materially  from  those  expressed  in the  Company's
forward-looking  statements in this report and presented elsewhere by management
from time to time.

     Early Stage of Product  Development;  Technological  Uncertainty.  To date,
substantially all of the Company's  revenues have consisted of payments received
under agreements with corporate partners and from government research contracts,
none of which provide for material future  funding.  The Company has received no
revenues to date from product  sales,  and does not expect to seek United States
regulatory  approval  for  sales of its  cancer  and  anti-restenosis  treatment
products before the year 2000. Royalties from the sale of the VERLUMA diagnostic
imaging agent will begin in 1997. The Company's current research and development
activities are focused primarily on its proposed therapeutic products, which are
in  an  early  stage  of  development.  In  preclinical  studies  the  Company's
pretargeting  technology has shown promise for the treatment of cancer tumors in
animals.  Results obtained in preclinical studies are not necessarily indicative
of results that will be obtained in human clinical trials.

    The Company will require collaborative  partners to assist in developing its
potential products,  and there can be no assurance that the Company will be able
to negotiate acceptable  collaborative  arrangements in the future. In addition,
the Company's  potential products will require  significant  additional research
and development and extensive clinical testing prior to commercial use.

    There can be no assurance that these potential products will be successfully
developed into drugs that can be  administered  to humans or that any such drugs
or related  therapies will prove to be safe and effective in clinical  trials or
cost-effective to manufacture.  Further,  these potential  products may prove to
have  undesirable  and  unintended  side effects that may prevent or limit their
commercial use.

    History  of  Losses;  Need  for  Additional  Funds.  The  Company  has  been
unprofitable  since inception and expects to incur  additional  operating losses
over the next several years. These operating losses may fluctuate from period to

                                       9
<PAGE>

period. The Company's existing capital resources and interest income thereon are
currently expected to be sufficient to fund the Company's operations through the
second  quarter  of 1998.  The  Company's  actual  expenditures  will  depend on
numerous  factors,  including  results of research and  development  activities,
clinical   trials,   the  levels  of  resources  that  the  Company  devotes  to
establishing and expanding marketing and manufacturing capabilities, competitive
and  technological  developments and the timing and cost of  relationships  with
parties to  collaborative  agreements.  The  Company  will  require  substantial
additional  funds to  complete  the  development  of its  therapeutic  products.
Adequate  funds for  these  purposes,  whether  through  additional  financings,
collaborative  arrangements with corporate sponsors or other sources, may not be
available when needed or on terms favorable to the Company.

    Dependence on  Suppliers.  The Company  depends on the timely  delivery from
suppliers of certain  materials and services.  In connection  with its research,
preclinical   studies  and  clinical   trials,   the  Company  has  periodically
experienced  interruption in the supply of monoclonal antibodies,  including the
1990 loss of its former sole supplier of the antibody used in its cancer imaging
products.  Interruptions  in these and other supplies could occur in the future.
The  Company  will  need  to  develop  sources  for  commercial   quantities  of
yttrium-90,  the radionuclide used in its proposed cancer therapeutic  products,
and for the  antibody,  streptavidin  and  clearing  agent used in the  AVICIDIN
agent.  The  catheter  used to deliver the  Company's  proposed  anti-restenosis
products has not yet been approved for sale by the FDA;  commercial  use of such
catheter depends on receiving such approval. In addition, the Company depends on
a supply of the catheter  from its  manufacturer,  and there can be no assurance
that the manufacturer  will provide a timely and adequate supply of catheters to
the Company.  Any failure by the  manufacturer  to timely and adequately  supply
catheters  would  have a material  adverse  effect on the  Company's  ability to
commercialize  these  products.  Also,  the  drug  used  in the  atherosclerosis
clinical trial to raise activated TGF(beta) levels is dependent on a third party
both for supply and for  agreement  to continue  testing  and  commercialization
after Phase I.

     Dependence  on Others  for  Commercial  Manufacturing  and  Marketing.  The
Company  has  no  manufacturing  facilities  for  commercial  production  of its
products  under  development.  The  Company  also has no  experience  in  sales,
marketing or distribution.  The Company's strategy for  commercialization of its
products   requires   entering   into  various   arrangements   with   corporate
collaborators,  licensors,  licensees and others to manufacture,  distribute and
market its  products.  The Company  will depend on the success of these  outside
parties in performing their responsibilities. Although the Company believes that
parties  to its  existing  and any  future  arrangements  will have an  economic
motivation to  successfully  perform  their  contractual  responsibilities,  the
amount and timing of resources to be devoted to these  activities are not within
the Company's control.  There can be no assurance that such parties will perform
their  obligations  as expected,  that the Company will derive any revenues from
such  arrangements  or that the Company's  reliance on others for  manufacturing
products will not result in unforeseen problems with product supply. The Company
entered into agreements  with Boehringer  Ingelheim and DuPont Merck under which
Boehringer  Ingelheim has worldwide  manufacturing rights and non-North American
marketing rights and DuPont Merck has exclusive North American  marketing rights
to the Company's  VERLUMA lung cancer imaging  product.  The Company  intends to
seek collaborative partners to assist in developing, manufacturing and marketing
its therapeutic  products under development.  There can be no assurance that the
Company will be able to negotiate acceptable  collaborative  arrangements in the
future  or  that  its  current  or  future  collaborative  arrangements  will be
successful.

    Competition.  Cancer imaging and therapy, and cardiovascular disease product
development is highly  competitive.  There are numerous  competitors  developing
products to detect, stage or treat each of the diseases for which the Company is
seeking to develop products.  Some competitors have adopted product  development
strategies  similar to the  Company's  approach  of  targeting  cancer  cells by
linking  radionuclides to monoclonal  antibodies.  Many emerging  companies have
corporate partnership  arrangements with large, established companies to support
research,  development  and  commercialization  efforts of products  that may be
competitive with those being developed by the Company. In addition,  a number of
 
                                       10
<PAGE>
                                      
established  pharmaceutical  and chemical  companies are developing  proprietary
technologies or have enhanced their  capabilities by entering into  arrangements
with,  or  acquiring,   companies  with  proprietary  monoclonal  antibody-based
technology  or other  technologies  applicable  to the imaging or  treatment  of
cancer and  restenosis.  Many major  pharmaceutical  companies,  either alone or
through   collaboration  with  smaller   companies,   have  active  programs  in
anti-restenosis therapy.  Moreover, metal stents are now being used to hold open
the arteries after angioplasty by mechanical means. Several major pharmaceutical
companies market a drug from the class of HMG CoA-reductase inhibitors that have
been shown to reduce risk of heart  attack.  Many of the  Company's  existing or
potential  competitors have or have access to substantially  greater  financial,
research and development,  marketing and production  resources than those of the
Company and may be better equipped than NeoRx to develop, manufacture and market
competing products.  The Company's  competitors already have, or may develop and
introduce  products  that are more  effective  than those of the Company or that
would render the  Company's  technology  and  products  under  development  less
competitive, uneconomical or obsolete.

    Technological  Uncertainties  Regarding  Human  Immune  Response  to Foreign
Proteins.  The Company's AVICIDIN cancer therapy product, which is in Phase I/II
clinical testing,  currently uses a monoclonal antibody of murine (mouse) origin
coupled to streptavidin,  a protein of bacterial origin.  These molecules appear
as foreign proteins to the human immune system,  which develops its own antibody
in  response.  The HAMA  response,  or the  "human  anti-streptavidin  antibody"
("HASA")  response,  may  limit  the  number  of  doses  that may be  safely  or
effectively  administered to a patient,  thereby limiting a product's  efficacy.
The  Company  believes  that  humanized  antibodies  may  reduce  HAMA  and that
modification of streptavidin  may reduce HASA. Gene cloning  technology  permits
splicing  of human and  murine  antibody  portions  together,  thereby  yielding
humanized  molecules.  Although the Company has produced a humanized  version of
the murine antibody used in AVICIDIN agent and has initiated a collaboration  to
modify  streptavidin,  there can be no  assurance  that either  would reduce the
extent to which HAMA or HASA may limit the effectiveness of the Company's cancer
therapy products or that the Company will  successfully  commercialize  products
incorporating the humanized antibody.

     Uncertainty  Regarding Patents and Proprietary  Rights. The patent position
of biotechnology  firms generally is highly uncertain and involves complex legal
and factual questions,  and currently no consistent policy has emerged regarding
the breadth of claims allowed in biotechnology  patents.  Products and processes
important to NeoRx are subject to this uncertainty. Accordingly, there can be no
assurance  that the  Company's  patent  applications  will result in  additional
patents being issued or that, if issued,  patents will afford protection against
competitors  with similar  technology,  nor can there be any assurance  that any
patents  issued to the Company will not be  infringed  by or designed  around by
others or that others  will not obtain  patents  that the Company  would need to
license or design around.  Moreover,  the technology applicable to the Company's
products  is  developing   rapidly.   Research   institutes,   universities  and
biotechnology  companies,   including  the  Company's  competitors,  have  filed
applications  for,  or  have  been  issued,  numerous  patents  and  may  obtain
additional  patents and  proprietary  rights  relating to products or  processes
competitive with or relating to those of the Company.  The scope and validity of
such patents, the extent to which the Company may be required to obtain licenses
thereunder or under other  proprietary  rights and the cost and  availability of
licenses  are unknown.  To the extent  licenses  are  required,  there can be no
assurance that they will be available on  commercially  reasonable  terms, if at
all. The Company also relies on unpatented proprietary technology.  There can be
no assurance that others will not independently develop substantially equivalent
proprietary  information  and  techniques,  that others will not otherwise  gain
access to the Company's proprietary technology,  or disclose such technology, or
that  the  Company  can  meaningfully  protect  its  rights  in such  unpatented
proprietary technology.

    Delays and Costs Resulting From Government  Regulation.  The manufacture and
marketing of the Company's  proposed  products and its research and  development
activities  are  subject to  regulation  for  safety,  efficacy  and  quality by
numerous  government  authorities  in the  United  States  and other  countries.

                                       11
<PAGE>

Clinical  trials,  manufacturing  and  marketing  of products are subject to the
rigorous  testing  and  approval  processes  of the FDA and  equivalent  foreign
regulatory  authorities.  Clinical  trials and  regulatory  approval  can take a
number  of years to  accomplish  and  require  the  expenditure  of  substantial
resources.  There can be no assurance  that  clinical  trials will be started or
completed  successfully within any specified time period. Delays in approval can
occur  for a number  of  reasons,  including  the  Company's  failure  to obtain
necessary  supplies of monoclonal  antibodies or other  materials or to obtain a
sufficient  number of  available  patients to support the claims  necessary  for
regulatory approval. There can be no assurance that requisite FDA approvals will
be obtained on a timely  basis,  if at all, or that any  approvals  granted will
cover all the  clinical  indications  for which the Company  may seek  approval.
Delays or  failure  to obtain  regulatory  approval  would  adversely  affect or
prevent the marketing of other products developed by the Company and its ability
to receive royalty or other product  revenues.  The manufacture and marketing of
drugs are subject to continuing the FDA review and later discovery of previously
unknown  problems  with a  product,  manufacturer  or  facility  may  result  in
restrictions, including withdrawal of the product from the market. Marketing the
Company's  products  abroad will require  similar  regulatory  approvals  and is
subject to similar  risks.  In  addition,  the  Company is unable to predict the
extent of adverse  governmental  regulation that might arise from future U.S. or
foreign government action.

    Risk of Product Liability. The testing, manufacturing, marketing and sale of
human  healthcare  products under  development by the Company entail an inherent
risk that  product  liability  claims  will be  asserted  against  the  Company.
Although the Company is insured  against  such risks up to a $10 million  annual
aggregate limit in connection with human clinical trials and commercial sales of
its products  under  development,  there can be no assurance  that the Company's
present product  liability  insurance is adequate.  A product liability claim in
excess of the Company's  insurance coverage could have a material adverse effect
on the  Company and may prevent the  Company  from  obtaining  adequate  product
liability insurance in the future on affordable terms. In addition, there can be
no assurance  that product  liability  coverage will continue to be available in
sufficient amounts or at an acceptable cost.

     Uncertainty of Pharmaceutical Pricing, Healthcare Reform and Reimbursement.
The levels of revenues and  profitability  of  pharmaceutical  companies  may be
affected by the  continuing  efforts of  government  and  third-party  payors to
contain or reduce the costs of healthcare through various means. For example, in
certain foreign markets pricing or profitability of prescription pharmaceuticals
is subject to governmental  control. In the United States,  there have been, and
the  Company  expects  that there will  continue  to be, a number of federal and
state proposals to implement similar governmental  control. It is uncertain what
legislative proposals will be adopted or what actions federal,  state or private
payors for healthcare  goods and services may take in response to any healthcare
reform proposals or legislation. Even in the absence of statutory change, market
forces are changing the healthcare sector. The Company cannot predict the effect
healthcare reforms may have on its business,  and there can be no assurance that
any such  reforms  will not  have a  material  adverse  effect  on the  Company.
Further,  to the extent that such  proposals or reforms have a material  adverse
effect  on  the  business,   financial  condition  and  profitability  of  other
pharmaceutical  companies that are prospective  collaborators for certain of the
Company's  potential  products,  the  Company's  ability  to  commercialize  its
products under development may be adversely affected.  In addition,  both in the
United States and elsewhere,  sales of  prescription  pharmaceuticals  depend in
part on the  availability  of  reimbursement  to the consumer  from  third-party
payors, such as governmental and private insurance plans. Third-party payors are
increasingly  challenging the prices charged for medical  products and services.
If the Company succeeds in bringing one or more products to market, there can be
no assurance  that these  products  will be considered  cost-effective  and that
reimbursement  to the consumer  will be available or will be sufficient to allow
the Company to sell its products on a competitive basis.

    Reliance on Key Personnel.  The Company's success will depend in part on the
efforts of certain  key  scientists  and  management  personnel.  Because of the
specialized nature of the Company's business,  the Company's ability to maintain
its  competitive  position  will  depend in part on its  ability to attract  and

                                       12
<PAGE>

retain qualified personnel. Competition for such personnel is intense. There can
be no  assurance  that the  Company  will be able to hire  sufficient  qualified
personnel on a timely basis or retain such personnel. The loss of key management
or scientific  personnel could have an adverse effect on the Company's business.
The Company does not maintain key person  insurance on any of its  scientists or
management personnel.

    Compliance With Environmental Regulations;  Hazardous Materials. The Company
is subject to federal,  state and local laws,  rules,  regulations  and policies
governing the use,  generation,  manufacture,  storage,  air emission,  effluent
discharge,  handling and disposal of certain  materials and wastes in connection
with its research and development  activities and its  manufacturing of clinical
trial  materials.  Although the Company believes that it has complied with these
laws and regulations in all material respects, there can be no assurance that it
will not be required to incur significant costs to comply with environmental and
health  and  safety  regulations  in the  future.  The  Company's  research  and
development and clinical  manufacturing  processes involve the controlled use of
small  amounts of  hazardous  and  radioactive  materials.  Although the Company
believes that its safety procedures for handling and disposing of such materials
comply with the standards  prescribed by such laws and regulations,  the risk of
accidental  contamination  or injury from these  materials  cannot be completely
eliminated.  In the event of such an accident,  the Company could be held liable
for any resulting  damages,  and any such  liability  could exceed the Company's
resources.

Employees

    As of March 7, 1997, the Company had 70 full-time  employees and 9 part-time
employees,  20 of whom hold  Ph.D.  degrees  and two of whom hold M.D.  degrees.
Sixty-one  employees  were engaged in research,  development  and  manufacturing
activities and 18 were employed in finance and administration.

    The Company considers its relations with its employees to be excellent. None
of the Company's employees are covered by a collective bargaining agreement.

Item 2. Properties

    The Company occupies approximately 36,000 square feet of office,  laboratory
and manufacturing space at 410 West Harrison Street, Seattle,  Washington, under
a lease that expires May 31, 2001. The lease is renewable through May 31, 2006.

    NeoRx believes its facilities are in good condition and are adequate for all
present  uses. A portion of its  facilities is used for pilot  manufacturing  to
produce certain of its products under development. The Company believes that the
production  capacity of its pilot  facility is adequate to satisfy the Company's
Phase I clinical trial  requirements,  and it passed an FDA inspection for these
purposes in 1993 and a Washington  State Board of Pharmacy  inspection  in 1996.
The Company's strategy is to license manufacturing rights for its products,  but
it may  decide to produce  certain  components  of its  therapy  products.  Such
production would require a further  investment in facilities and equipment,  the
cost of which cannot be currently estimated.

Item 3. Legal Proceedings

    On June 6, 1996, the United States District Court for the Southern  District
of New York dismissed all claims against the Company in a purported class action
suit  against  David  Blech,  D. Blech & Co.  and a number of other  defendants,
including 11 publicly traded  biotechnology  companies,  of which one was NeoRx,
that had been named in an amended  complaint on March 27, 1995.  The  plaintiffs
have not appealed the order.  On July  26,1996,  the  plaintiffs  filed a second
amended  pleading that did not include any claims against the Company.  NeoRx is
not a defendant in the subject suit.

         of Operations
  
Results of Operations

    The NeoRx Corporation ("NeoRx" or the "Company") develops  biopharmaceutical
products for the detection and  treatment of human  diseases.  The Company is no
longer  considered a company in the  development  stage as the  Company's  first
product,  VERLUMA(TM)  Small Cell Lung Cancer  Imaging Kit,  received  marketing
approval by the Food and Drug  Administration  (the "FDA") in August 1996. Sales
began in February 1997,  from which NeoRx will receive  royalties.  To date, the
Company's  revenues have consisted  principally of license fees from  Boehringer
Ingelheim International GmbH ("Boehringer Ingelheim"),  payments from The DuPont
Merck Pharmaceutical  Company ("DuPont Merck"),  Sterling Winthrop Inc. and from
federal  government  research  contracts.   The  Company  plans  to  enter  into
additional  collaborative  agreements  with  corporate  partners,  but  does not
currently have firm commitments for any such agreements.  Expenses incurred have
been  primarily  for research and  development  activities  and  administration.
Successful  future  operations  depend  upon the  Company's  ability to develop,
obtain regulatory approval for and commercialize its products.  The Company will
require a substantial  amount of additional funds to complete the development of
most of its products and to fund additional  operating  losses which the Company
expects to incur during the next several years.

Years Ended December 31, 1996, 1995 and 1994

   The Company's revenues in 1996, 1995 and 1994 were $4.8 million,  $.3 million
and $1.6  million,  respectively,  and  consisted  of license  fees and payments
received under its  collaborative and license  agreements.  Revenues in 1996 and
1994  consisted  primarily  of license  fees of $4.5  million and $1.4  million,
respectively,  from DuPont Merck for exclusive  North American  rights to market
NeoRx's VERLUMA lung cancer imaging products.  As part of the agreement,  DuPont
Merck also purchased 269,000 shares of Common Stock in October 1994.

   The Company's total operating expenses were $14.8 million,  $13.3 million and
$12.6 million in 1996, 1995 and 1994, respectively.  Of these amounts,  research
and development expenditures were $9.8 million, $8.7 million and $7.5 million in
1996, 1995 and 1994,  respectively.  Research and development expenses increased
12% in 1996 and 16% in 1995. The increase in research and  development  expenses
in  1996  and  1995  was  primarily  due  to  activities  relating  to  antibody
humanization,  increased  clinical trial  activities and a one-time  license fee
payment in 1995.  Approximately  100% of the Company's  research and development
expenses  in 1996  and  1995  were  attributable  to the  Company's  self-funded
research  programs,  and approximately 98% were self-funded in 1994. General and
administrative  expenses  were $5.0  million,  $4.6  million and $5.1 million in
1996, 1995 and 1994, respectively. General and administrative expenses increased
8% in 1996 and decreased 9% in 1995. The increase in general and  administrative
expenses  in 1996 was  principally  due to patent  filing  costs and other legal
expenses associated with collaborative  agreements.  The decrease in general and
administration  expenses in 1995 resulted  primarily from reduced legal fees and
costs  associated  with  the  Company's  patent  enforcement  suit  against  and
counterclaim by Immunomedics, Inc. which was settled in 1994.

   Investment and interest income was $1.1 million, $1.0 million and $.9 million
in  1996,  1995  and  1994,  respectively.  The  increase  in 1996  and 1995 was
primarily due to higher average cash balances resulting from sales of Common and
Preferred Stock. Interest expense was $.1 million in 1996, 1995 and 1994.

Management's  Discussion and  Analysis of  Financial  Condition  and  Results of
Operations (Continued)

Liquidity and Capital Resources

   The Company's operations have been financed primarily by funds raised through
the issuance of equity  securities and amounts received under  manufacturing and
marketing licenses.  Sales of the Company's Common and Preferred Stock raised an
aggregate  of $21.2  million  and cash fees  received  from  license  agreements
totaled $5.9 million during the past three years.

   The Company has invested $.7 million in  equipment,  furniture  and leasehold
improvements  over the past three  years,  primarily to support its research and
manufacturing  activities. As of December 31, 1996, the Company was committed to
spending  approximately  $2.2 million  pursuant to operating  and capital  lease
obligations.

   The  Company  has no  material  commitments  for  capital  expenditures.  The
Company's strategy is to form corporate alliances with pharmaceutical  companies
to provide  for the  manufacture  of its  products  under  development,  thereby
avoiding the need to make significant investments in production capacity.

   During  1996,  total  cash,  cash  equivalents  and  short-term   investments
increased $2.1 million and improved the Company's current ratio to 9.0 from 7.5.
The increases  were  primarily due to the receipt of a $4.5 million  license fee
payment and stock sales.

   In January 1996, the Company issued 370,000 shares of Common Stock and 47,000
shares of Series 2  Convertible  Preferred  Stock in  private  transactions  and
received net proceeds of $6.6 million.  In October 1995, the Company  registered
650,000  shares of Common Stock to be sold from time to time.  During 1996,  the
Company  issued  464,000  shares and received net proceeds of $3.8 million,  and
during 1995, the Company issued 186,000 shares and received net proceeds of $1.2
million.  Also during 1995, the NeoRx received net proceeds of $8.3 million from
the  sale of 1.4  million  units  consisting  of  Common  Stock  and  three-year
warrants.  In October 1994, the Company received $2.0 million from DuPont Merck,
for which DuPont Merck received  VERLUMA  marketing  rights in North America and
269,000 shares of NeoRx Common Stock.

   The Company's cash investment  policy is to earn a market rate of interest on
its  marketable  securities  while  assuming  minimal  risk  of  principal.  The
investment  portfolio  must  meet  the  following  objectives:  preservation  of
principal,  fulfillment of liquidity  needs,  reasonable  yield and avoidance of
inappropriate  concentrations.  All investments  must carry an investment  grade
rating and no single non-Federal government issue may represent more than 10% of
portfolio assets.

   The Company  expects that its capital  resources and interest  income will be
sufficient  to finance its  currently  anticipated  working  capital and capital
requirements  through the second quarter of 1998. The Company's  working capital
and capital requirements will depend upon numerous factors, including results of
research and development  activities,  clinical trials,  the levels of resources
that  the  Company   devotes  to  establishing   and  expanding   marketing  and
manufacturing  capabilities,  competitive and technological developments and the
timing and cost of relationships with parties to collaborative  agreements.  The
Company will need to raise substantial  additional funds to conduct research and
development  activities,  preclinical  studies and clinical trials  necessary to
bring  its  products  to  market,   and  to  establish   marketing  and  limited
manufacturing  capabilities.  The  Company  intends to seek  additional  funding
through  public  or  private  equity  financings,  arrangements  with  corporate
collaborators or other sources.  Adequate funds may not be available when needed
or on terms acceptable to the Company.

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders of NeoRx Corporation:

    We have audited the  accompanying  balance  sheets of NeoRx  Corporation,  a
Washington  corporation,  as of  December  31,  1996 and 1995,  and the  related
statements of operations,  cash flows and  shareholders'  equity for each of the
years ended December 31, 1996, 1995 and 1994. These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

    We conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion,  the financial  statements referred to above present fairly,
in all material  respects,  the financial  position of NeoRx  Corporation  as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for each of the years ended December 31, 1996, 1995 and 1994, in conformity with
generally accepted accounting principles.

                                                      ARTHUR ANDERSEN LLP

                         NOTES TO FINANCIAL STATEMENTS


NOTE 1.  The Company

     NeoRx Corporation ("NeoRx" or the "Company"),  incorporated in the state of
Washington,  develops biopharmaceutical products for the detection and treatment
of human  diseases.  The  Company  is no  longer  considered  a  company  in the
development stage and will therefore no longer present results of operations and
cash  flows  for  the  period  from  inception.  The  Company's  first  product,
VERLUMA(TM) Small Cell Lung Cancer Imaging Kit, received  marketing  approval by
the Food and Drug  Administration  (the  "FDA") in August  1996.  Sales began in
February 1997, from which NeoRx will receive  royalties.  The Company's revenues
have   consisted   principally  of  license  fees  from   Boehringer   Ingelheim
International  GmbH  ("Boehringer  Ingelheim"),  payments  from The DuPont Merck
Pharmaceutical Company ("DuPont Merck"), Sterling Winthrop Inc. and from federal
government  research  contracts.  The Company's  development  activities involve
inherent risks. These risks include, among others,  dependence on key personnel,
availability  of  raw  materials,  determination  of  the  patentability  of the
Company's  products and  processes  and approval by the FDA before the Company's
products may be sold  domestically.  Expenses  incurred have been  primarily for
research  and  development  activities  and  administration.  Successful  future
operations  depend  upon the  Company's  ability to develop,  obtain  regulatory
approval  for and  commercialize  its  products.  The  Company  will  require  a
substantial  amount of additional  funds to complete the  development of most of
its products and to fund additional  operating  losses which the Company expects
to incur during the next several years.

NOTE 2.  Summary of Significant Accounting Policies

     Cash Flows. For the purpose of the  accompanying  Statements of Cash Flows,
the Company considers all highly liquid investments with a remaining maturity of
three months or less when purchased to be cash equivalents.

     No capital lease  obligations were incurred during the years ended December
31, 1996 and 1994. Capital lease obligations  incurred to acquire equipment were
$143,000 in 1995.

     Interest  paid by the Company was  $143,000,  $141,000 and $127,000 for the
years ended December 31, 1996, 1995 and 1994, respectively.

     In January  1996,  the Company sold  approximately  47,000  shares Series 2
Convertible  Preferred  Stock,  $.02 par value per share  ("Series  2  Preferred
Stock") at a stated  value of $100 per share that may be  converted  into Common
Stock valued at $120.50.  A non-cash  dividend charge of $956,000 was recognized
by the Company in 1996 for the amount of the excess of the conversion value over
the stated value.

     During the year  1996,  the  Company  exchanged  40,000  shares of Series 2
Preferred  Stock and paid accrued  dividends by issuing 892,000 shares of Common
Stock.  In June  1995,  the  Company  exchanged  90,000  shares  of  Convertible
Exchangeable  Preferred  Stock,  Series 1, $.02 par value per share  ("Series  1
Preferred Stock") and paid accrued dividends by issuing 254,000 shares of Common
Stock.

     Estimates and  Uncertainties.  The  preparation of financial  statements in
conformity with generally accepted accounting  principles requires management to
make estimates and  assumptions  that affect the reported  amounts of assets and
liabilities. Actual results could differ from those estimates.

                               NEORX CORPORATION
                   NOTES TO FINANCIAL STATEMENTS (Continued)

     Research and Development Revenues and Expenses. Revenues from collaborative
agreements are recognized as earned as the Company performs research  activities
under the terms of each  agreement.  Billings  in excess of  amounts  earned are
classified as deferred  revenue.  License fees earned are  recognized as revenue
unless  subject to a  contingency,  which results in a deferral of revenue until
the  contingency is satisfied.  Research and  development  costs are expensed as
incurred.

     Inventories.  Inventories  consist primarily of raw materials priced at the
lower of cost (first-in, first-out) or market.

     Facilities and Equipment.  Facilities  and equipment,  including  equipment
under capital  leases,  are stated at cost.  Depreciation  is provided using the
straight-line  method over an estimated  useful life of five years for equipment
and furniture.  Leasehold  improvements  and equipment  under capital leases are
amortized  using  the  straight-line  method  over the  shorter  of the  assets'
estimated useful lives or the terms of the leases.

    Net Loss Per Common  Share.  Net loss per  common  share is  computed  after
deduction of preferred  stock  dividends and is based upon the weighted  average
number of shares of Common Stock  outstanding  during each period.  Common Stock
equivalents include shares issuable upon the exercise of outstanding warrants or
stock  options,  but are not included in the  computation  of net loss per share
because the effect of including such shares would be antidilutive.

NOTE 3.  Short-Term Investments

     Short-term investments consisted of the following (in thousands):

NOTE 5.  Leases

     The Company leases certain  equipment  under capital leases which expire on
various dates through 1999.  The total amount of equipment  under capital leases
included in facilities  and  equipment on the  accompanying  balance  sheets was
$294,000 at December 31, 1996 and 1995, and accumulated  amortization applicable
to such  leases  was  $184,000  and  $122,000  at  December  31,  1996 and 1995,
respectively.

     The lease for the Company's principal location expires in 2001 and contains
one five-year  renewal option.  Total rent payments under operating  leases were
$515,000,  $450,000 and $418,000 for the years ended December 31, 1996, 1995 and

NOTE 6.  Revenues

     In 1996,  the Company  recorded as revenue a $4,500,000  milestone  payment
from DuPont Merck upon FDA approval to market VERLUMA in the United  States.  In
October 1994, the Company entered into a marketing  agreement with DuPont Merck,
under which DuPont Merck  received  exclusive  North  American  rights to market
NeoRx's  VERLUMA  lung cancer  imaging  product that  incorporates  the NR-LU-10
antibody,  and 269,000  shares of Common  Stock.  In  exchange,  NeoRx  received
$2,000,000,  of which the excess of the fair value of the shares of Common Stock
issued was recorded as revenue.  The Company will receive  royalties on sales of
the product.

NOTE 7.  Convertible Subordinated Debentures

     The Company has  outstanding  $1,195,000  principal  amount of  Convertible
Subordinated Debentures, 9 3/4% (the "Debentures"), that will be retired June 1,
2000.  The  Debentures  are  convertible  at the option of the  holder  into the
Company's  Common  Stock at a conversion  price of $25.73 per share,  subject to
adjustment under certain conditions. Interest is payable semi-annually on June 1
and December 1. The Debentures are redeemable, in whole or in part, at any time,
at the option of the Company at 102.9% of par,

reducing to par by 1999,  together with accrued  interest.  The  Debentures  are
subordinated in right of payment to any outstanding  senior  indebtedness of the
Company, as defined in the indenture.

NOTE 8.  Contingencies

     Litigation.  On June 6, 1996,  the  United  States  District  Court for the
Southern  District of New York  dismissed  claims  against  NeoRx in a purported
class  action suit  against  David  Blech,  D. Blech & Co. and a number of other
defendants,  including 11 publicly traded biotechnology  companies, of which one
was NeoRx,  that had been named in an amended  complaint on March 27, 1995.  The
plaintiffs have not appealed the order. On July 26, 1996, the plaintiffs filed a
second  amended  pleading  which did not include any claims against the Company.
NeoRx is not a defendant in the subject suit.

     Product Liability. The testing, manufacturing,  marketing and sale of human
healthcare  products  by the  Company  entail  an  inherent  risk  that  product
liability claims will be asserted  against the Company.  The Company has product
liability  insurance coverage of $10,000,000 for aggregate claims that may arise
from the use of its products.

NOTE 9.  Shareholders' Equity

     Common Stock  Transactions.  During 1996, the Company issued 919,000 shares
of Common Stock and received  net  proceeds and services  valued at  $6,460,000.
During  1995,  the Company  issued  186,000  shares and received net proceeds of
$1,155,000.  In April and September  1995, the Company sold 1,557,000  shares of
Common Stock and 1,635,000  three-year  warrants to purchase  409,000  shares of
Common Stock,  exercisable at a price of $5.31 per share. Net proceeds  amounted
to  $8,309,000.  In October  1994,  the Company  issued to DuPont Merck  269,000
shares  of  Common  Stock in  connection  with  the  VERLUMA  marketing  license
agreement.

     During  1996,  the Company  exchanged  40,000  shares of Series 2 Preferred
Stock for  860,000  shares of Common  Stock and paid  accrued  dividends  on the
shares  valued at $174,000 by issuing  32,000  shares of Common  Stock.  In June
1995,  the  Company  exchanged  90,000  shares of Series 1  Preferred  Stock for
225,000 shares of Common Stock and paid accrued dividends on those shares valued
at $159,000 by issuing 29,000 shares of Common Stock.

     Preferred  Stock  Transactions.  Holders  of Series 1  Preferred  Stock are
entitled to receive an annual cash  dividend of $2.4375 per share if declared by
the  Board of  Directors  (the  "Board"),  payable  semi-annually  on June 1 and
December 1. Dividends are cumulative.  Each share of Series 1 Preferred Stock is
convertible  into  approximately  1.14  shares  of  Common  Stock,   subject  to
adjustment in certain events.  The Series 1 Preferred Stock is redeemable at the
option of the  Company at $25.73 per  share,  decreasing  to $25.00 per share by
1999.  Holders  of Series 1  Preferred  Stock have no voting  rights,  except in
limited circumstances.

     In June 1995,  the Company  exchanged  90,000  shares of Series 1 Preferred
Stock for 225,000  shares of Common  Stock.  (See  "Common  Stock  Transactions"
above.)

     Holders of Series 2  Preferred  Stock are  entitled  to receive  cumulative
dividends at the rate of 8% per annum compounded quarterly on the $100 per share
stated value of the Series 2 Preferred Stock.  The dividend is payable,  in cash
or Common  Stock at the  Company's  option,  at the time the Series 2  Preferred
Stock is redeemed or converted into Common Stock.  The Series 2 Preferred  Stock
is redeemable at the

option of the Company at $120.50 per share. Each share of the Series 2 Preferred
Stock is  convertible  at the option of the holder  into the number of shares of
Common Stock  determined by dividing $120.50 by the average stock market closing
bid price of the  Common  Stock for the five  trading  days  prior to the day of
conversion,  but not less than $4.41 nor more than $8.36 per share. The discount
to be realized by the  difference  between the  conversion  value and the stated
value of the Series 2 Preferred  Stock issued was recognized by the Company as a
non-cash  dividend  charge of  $956,000.  The  holders of the Series 2 Preferred
Stock  have no voting  rights,  except in  limited  circumstances.  The Series 2
Preferred  Stock ranks junior to the Company's  Series 1 Preferred  Stock, as to
dividends, distributions and payments in liquidation.

    In January  1996,  the Company  issued  47,000  shares of Series 2 Preferred
Stock and received net proceeds of  $4,418,000.  During 1996,  40,000  shares of
Series 2 Preferred Stock were converted to 860,000 shares of Common Stock.  (See
"Common Stock Transactions" above.)

    Shareholders'   Rights  Plan.  On  April  10,  1996,  the  Board  adopted  a
Shareholders'  Rights Plan  intended to protect  the rights of  shareholders  by
deterring coercive or unfair takeover tactics.  The Board declared a dividend to
holders  of  the  Company's  Common  Stock,   payable  on  April  19,  1996,  to
shareholders  of record on that date, of one preferred share purchase right (the
"Right")  for  each  outstanding  share  of  the  Common  Stock.  The  Right  is
exercisable 10 days following the offer to purchase or acquisition of beneficial
ownership  of 20% of the  outstanding  Common  Stock  by a  person  or  group of
affiliated  persons.  Each Right entitles the registered holder,  other than the
acquiring  person or group,  to purchase from the Company  one-hundredth  of one
share of Series A Junior  Participating  Preferred  Stock  ("Series A  Preferred
Stock") at a price of $40,  subject to  adjustment.  The Rights expire April 10,
2006.  The Series A Preferred  Stock will be entitled to a minimum  preferential
quarterly  dividend $1 per share and has liquidation  provisions.  Each share of
Series A  Preferred  Stock has 100 votes,  and will vote with the Common  Stock.
Prior to the acquisition by a person or group of 20% of the  outstanding  Common
Stock, the Board may redeem each Right at a price of $.001.

    In lieu of exercising the Right by purchasing one one-hundredth of one share
of Series A Preferred Stock,  the holder of the Right,  other than the acquiring
person or group, may purchase for $40, that number of the Company's Common Stock
having a market value of twice that price.

    The Board may,  without  further action by the  shareholders of the Company,
issue  preferred  stock in one or more series and fix the rights and preferences
thereof,  including dividend rights,  dividend rates,  conversion rates,  voting
rights, terms of redemption, redemption price or prices, liquidation preferences
and the number of shares  constituting  any series or the  designations  of such
series.

    Stock Options. The Company has two stock option plans, the 1994 Stock Option
Plan (the "1994 Plan") and the 1991 Stock Option Plan for Non-Employee Directors
(the "Directors  Plan").  The Company  accounts for its stock option plans under
the guidelines of Accounting  Principles  Board Opinion No. 25 ("APB 25"), under
which no  compensation  cost has been  recognized.  In 1996, the Company adopted
Statement of Financial  Accounting  Standards No. 123 ("SFAS 123"),  "Accounting
for Stock-Based  Compensation," effective for years beginning after December 15,
1995. The Company has continued to measure  compensation cost for employee stock
compensation plans under the guidelines of APB 25, as allowed by SFAS 123.

    Had  compensation  cost for these  stock  option  plans been  determined  in
accordance  with SFAS 123,  the  Company's  "Net  loss" and "Net loss per common
share" would have  increased to the  following  pro forma  amounts for the years
ended December 31, 1996 and 1995 (in thousands, except per share data):

</TABLE>

    Because  the SFAS 123  method of  accounting  has not been  applied to stock
options  granted before  January 1, 1995,  the resulting pro forma  compensation
cost may not be representative of that to be expected in future years.

    The 1994 Plan authorizes the Board or an Option  Committee  appointed by the
Board to grant  options  to  purchase a maximum  of  2,500,000  shares of Common
Stock.  The 1994 Plan replaced the 1984 Stock Option Plan that expired  November
1, 1994.  The 1994 Plan allows for the issuance of incentive  stock  options and
nonqualified   stock  options  to  employees,   officers,   Directors,   agents,
consultants,  advisors and  independent  contractors of the Company,  subject to
certain restrictions. All option grants expire ten years from the date of grant.
In general,  two-thirds of the option grants become exercisable in increments at
a rate of 25% per year over a  four-year  period  from the grant  date,  and the
remaining  one-third becomes exercisable over a period of one to nine years from
the grant date unless accelerated by the Option Committee. The exercise price of
options  granted  under the 1994 Plan is equal to the fair  market  value of the
Common Stock at the date of grant.  As of December 31, 1996,  there were 424,000
shares of Common Stock available for issuance under the 1994 Plan.

    In October  1996,  the Company  canceled and  reissued at an exercise  price
range of $5.13 - $5.25 per share,  the fair market  value of the Common Stock on
the date of  cancellation,  all options  held by  non-executive  employees  with
exercise prices greater than the price range of $5.13 - $5.25 per share.

    The Directors  Plan, as amended at its 1994 Annual Meeting of  Shareholders,
authorizes  the grant of stock options to  non-employee  Directors to purchase a
maximum of 250,000 shares of Common Stock.  Under the terms of the amended plan,
each eligible Director receives annually, concurrent with the annual election of
Directors,  an option to purchase  5,000  shares of Common  Stock at an exercise
price equal to the fair market  value of the Common  Stock on the date of grant.
The options become exercisable in two equal annual  installments  beginning with
the first annual meeting of  shareholders  after the date of grant. In addition,
each newly appointed non-employee Director receives a one-time initial option to
purchase  10,000  shares of Common Stock at an exercise  price equal to the fair
market  value of the Common  Stock on the date of grant.  Options  expire on the
earlier of ten years from the date of grant or five years  after the  Director's
termination  of service as a  Director.  As of  December  31,  1996,  there were
134,000 shares of Common Stock available for issuance under the Directors Plan.

     The fair value of each stock option  granted is valued on the date of grant
using the  Black-Scholes  option pricing model. The weighted average  grant-date
fair value of stock  options  granted  during 1996 was $3.66 per share using the
assumptions of expected  volatility of 70%, expected option lives of five to ten

</TABLE>

     The Company has  established a valuation  allowance  equal to the amount of
the deferred tax asset because the Company has not had taxable  income since its
inception and significant  uncertainty exists regarding the ultimate realization
of the deferred tax asset.  Accordingly,  no tax benefits  have been recorded in
the accompanying Statements of Operations.

     The  Company's net operating  loss  carryforwards  expire during the period
from 1999 to 2011. During 1994, the Company  experienced  sufficient  changes in
ownership such that the amount of net operating loss  carryforwards and research
and  development  carryforwards  available  to be used in any given year will be
limited  under  Sections  382 and 383 of the Internal  Revenue Code of 1986,  as
amended.  This  limitation  will  result  in  the  expiration  of  approximately
$43,000,000 of the Company's net operating loss  carryforwards and $2,400,000 of
the research and development credit carryforwards. Accordingly, the deferred tax
asset and  related  valuation  allowance  related  to these  carryforwards  were
reduced in 1994 by approximately $17,000,000.

NOTE 11.  Subsequent Events

     In February  1997, the Company's  marketing  partner,  DuPont Merck,  began
sales of  VERLUMA  Small Cell Lung  Cancer  Imaging  Kit,  the  Company's  first
product, from which NeoRx will receive royalties.

business with its directors,  officers and shareholders  and with  corporations,
associations,  firms and entities in which they are or may become  interested as
directors,  officers,  shareholders,  members or otherwise,  as freely as though

corporation  upon such contracts or  transactions.  In the absence of fraud,  no
such contracts or transactions  shall be void or voidable and no such directors,

sufficient  disclosure with respect to all contracts and transactions  with such
corporation, association, firm or entity.

                         STATEMENT OF RIGHTS AND PREFERENCES
           OF THE $2.4375 CONVERTIBLE EXCHANGEABLE PREFERRED STOCK, SERIES 1

                           ------------------------------

         (i)      DESIGNATION.  The designation of such series of the Preferred
Stock authorized shall be the "$2.4375 Convertible Exchangeable Preferred Stock,
Series 1" (the "Exchangeable  Preferred Stock"). The maximum number of shares of
Exchangeable Preferred Stock shall be 1,120,000.


         (ii) DIVIDENDS.  Holders of shares of Exchangeable Preferred Stock will

the Corporation legally available  therefor,  an annual cash dividend of $2.4375
per  share,  payable  in  semi-annual  installments  on  December  1 and  June 1

and any other Parity Preferred Stock (as defined in paragraph (iii) below),  all
dividends  paid and declared  upon shares of  Exchangeable  Preferred-Stock  and

Exchangeable  Preferred Stock and such other Parity Preferred Stock bear to each
other.  Except as set forth in the preceding  sentence,  unless full  cumulative
dividends on the Exchangeable  Preferred Stock have been paid,  dividends (other
than in Common  Stock of the  Corporation  (as defined in  subparagraph  (iv)(I)
below),  other stock  ranking  junior to the  Exchangeable  Preferred  Stock and
rights to acquire the  foregoing)  may not be paid or declared and set aside for
payment and other  distributions may not be made upon the Common Stock or on any
other  stock  of the  Corporation  ranking  junior  to or on a  parity  with the
Exchangeable  Preferred  Stock as to dividends,  nor may any Common Stock or any
other  stock  of the  Corporation  ranking  junior  to or on a  parity  with the
Exchangeable Preferred Stock as to dividends be redeemed, purchased or otherwise
acquired for any  consideration by the Corporation  (except for repurchases from
employees and  consultants at cost and except by conversion into or exchange for

                                       6

stock of the Corporation  ranking junior to the Exchangeable  Preferred Stock as
to  dividends).  Dividends  payable for any  partial  dividend  period  shall be
calculated  on the basis of a  360-day  year of 12 30-day  months.  Accrued  but
unpaid dividends shall not bear interest.

         For the purpose of determining the legality of dividends or redemptions
pursuant to Section 23A.08.420(2) (b) of the Revised Code of Washington,  or any
successor  statute,  dividends on or redemptions of the  Exchangeable  Preferred
Stock may be paid or made without  reference  to the amount  required to satisfy
the holders' Liquidation Preference.

         (iii) RANK. The shares of Exchangeable Preferred Stock shall rank prior
to the shares of Common Stock and of any other class of stock of the Corporation
ranking junior to the Exchangeable Preferred Stock upon liquidation,  so that in
the event of any  liquidation,  dissolution  or winding  up of the  Corporation,
whether  voluntary or  involuntary,  the holders of the  Exchangeable  Preferred
Stock  shall  be  entitled  to  receive  out of the  assets  of the  Corporation
available for distribution to its stockholders, whether from capital, surplus or
earnings,  before any  distribution is made to holders of shares of Common Stock
or any other  such  junior  stock,  an amount  equal to  $25.00  per share  (the
"Liquidation  Preference" of a share of  Exchangeable  Preferred  Stock) plus an
amount equal to all  dividends  (whether or not earned or declared)  accumulated
and unpaid on the shares of  Exchangeable  Preferred  Stock to the date of final
distribution.  If,  upon  any  liquidation,  dissolution  or  winding  up of the
Corporation,  the assets of the Corporation, or proceeds thereof,  distributable
among the holders of shares of Exchangeable Preferred Stock and Parity Preferred
Stock shall be insufficient to pay in full the  preferential  amount  aforesaid,
then such assets,  or the proceeds  thereof,  shall be distributable  among such
holders ratably in accordance with the respective amounts which would be payable
on such shares if all amounts payable  thereon were paid in full.  After payment
of the full amount of the  Liquidation  Preference  and such  dividends to which
holders of shares of Exchangeable  Preferred Stock are entitled,  the holders of
shares of  Exchangeable  Preferred  Stock will not be  entitled  to any  further
participation in any distribution of assets by the Corporation. For the purposes
hereof,  neither a  consolidation  or merger of the  Corporation  with any other
corporation,  nor a sale or  transfer  of all or any  part of the  Corporation's
assets for cash or securities shall be considered a liquidation,  dissolution or
winding up of the Corporation.

         For the purposes of this statement of Rights and  Preferences any stock
of any class or series of the Corporation shall be deemed to rank:

                  (a)  prior to  shares  of the  Exchangeable  Preferred  Stock,
either as to  dividends  or upon  liquidation,  if the  holders of stock of such
class or  series  shall be  entitled  by the terms  thereof  to the  receipt  of
dividends or of amounts  distributable upon liquidation,  dissolution or winding

                                       7
<PAGE> 

up, as the case may be, in  preference  or  priority to the holders of shares of
the Exchangeable Preferred Stock;

                  (b) on a parity  with  shares  of the  Exchangeable  Preferred
Stock,  either as to dividends or upon liquidation,  whether or not the dividend
rates,  dividend  payment dates,  or redemption or liquidation  prices per share
thereof be different from those of the Exchange- able  Preferred  Stock,  if the
holders of stock of such class or series shall be entitled by the terms  thereof
to the  receipt of  dividends  or of  amounts  distributable  upon  liquidation,
dissolution or winding up, as the case may be, in proportion to their respective
dividend rates or liquidation prices, without preference or priority of one over
the other as between  the  holders  of such  stock and the  holders of shares of
Exchangeable  Preferred Stock (the term "Parity  Preferred  Stock" being used to
refer to any stock on a parity with the shares of Exchangeable  Preferred Stock,
either as to dividends or upon liquidation as the context may require); and

                  (c)  junior  to shares of the  Exchangeable  Preferred  Stock,
either as to dividends or upon liquidation,  if such class shall be Common Stock
or if the holders of the  Exchangeable  Preferred Stock shall be entitled to the
receipt of dividends or of amounts  distributable upon liquidation,  dissolution
or winding up, as the case may be, in  preference  or priority to the holders of
stock of such class or series.

         (iv)     CONVERSION.

                  (I) Subject to and upon compliance with the provisions of this
paragraph (iv), the holder of a share of Exchangeable Preferred Stock shall have
the right, at such holder's option, at any time, to convert such share into such
number of fully paid and non-assessable shares of Common Stock (calculated as to
each conversion to the nearest 1/100th of a share) as the Liquidation Preference
of such share  surrendered for conversion is a multiple of the Conversion  Price
(as  defined  below) and by  surrender  of such share so to be  converted,  such
surrender  to be  made  in the  manner  provided  in  subparagraph  (II) of this
paragraph (iv); PROVIDED,  HOWEVER,  that the right to convert shares called for
redemption  pursuant to paragraph  (viii) or for exchange  pursuant to paragraph
(vii)  shall  terminate  at the  close of  business  on the date  fixed for such
redemption or exchange, as the case may be, unless the Corporation shall default
in making  payment of the amount  payable upon such  redemption or in making the
exchange  and payment of any amount  payable upon such  exchange.  A holder of a
share of Exchangeable  Preferred Stock is not entitled to any rights of a holder
of Common  Stock  until such  holder has  converted  such share of  Exchangeable
Preferred Stock.

         The term "Common Stock" shall mean the Common Stock, $.02 par value, of
the  Corporation  as the same exists on the date of this statement of Rights and

                                       8
<PAGE> 

Preferences or as such stock may be constituted  from time to time,  except that
for the purpose of  subparagraph  (V) of this  paragraph  (iv) the term  "Common
Stock"  shall  also mean and  include  stock of the  Corporation  of any  class,
whether now or hereafter  authorized,  which shall have the right to participate
in the  distribution  of either  earnings or assets of the  Corporation  without
limit as to amount or percentage.

         The term "Conversion Price" shall mean $5.50, as adjusted in accordance
with the provisions of this paragraph (iv).

         The term  "Liquidation  Preference" shall have the meaning specified in
paragraph (iii).

                  (II) In order to exercise the conversion privilege, the holder
of each share of  Exchangeable  Preferred  Stock to be converted shall surrender
the certificate  representing  such share at the office of the conversion  agent
for the  Exchangeable  Preferred Stock in the Borough of Manhattan,  City of New
York or Seattle, Washington, appointed for such purpose by the Corporation, with
the Notice of Election to Convert on the back of said certificate  completed and
signed.  Unless the shares  issuable on conversion  are to be issued in the same
name as the  name in  which  such  share  of  Exchangeable  Preferred  Stock  is
registered,  each share  surrendered  for  conversion  shall be  accompanied  by
instruments of transfer, in form satisfactory to the Corporation,  duly executed
by the holder or the holder's duly authorized  attorney and an amount sufficient
to pay any transfer or similar tax.

         The holders of shares of  Exchangeable  Preferred Stock at the close of
business  on a dividend  payment  record  date shall be  entitled to receive the
dividend  payable on such  shares on the  corresponding  dividend  payment  date
notwithstanding  the conversion  thereof after such dividend payment record date
or the  Corporation's  default in payment of the dividend  due on such  dividend
payment date.  However,  shares of Exchangeable  Preferred Stock surrendered for
conversion  during the period  between  the close of  business  on any  dividend
payment  record date and the opening of business on the  corresponding  dividend
payment date (except  shares called for  redemption on a redemption  date during
such period) must be  accompanied  by payment of an amount equal to the dividend
payable on such shares on such dividend  payment date (the  "dividend  amount").
The dividend with respect to a share of Exchangeable  Preferred Stock called for
redemption  on a  redemption  date between the close of business on any dividend
payment  record date and the opening of business on the  corresponding  dividend
payment  date shall be payable on such  dividend  payment  date to the holder of
such share on such dividend payment record date  notwithstanding  the conversion
of such share of Exchangeable Preferred Stock after such dividend payment record
date and prior to such dividend  payment date,  and the holder  converting  such
share of  Exchangeable  Preferred  Stock  need not  include  a  payment  of such

                                       9
<PAGE>
  
dividend amount upon surrender of such share of Exchangeable Preferred Stock for
conversion.  The holders of shares of Exchangeable Preferred Stock on a dividend
payment record date who (or whose transferees)  convert any of such shares on or
after the corresponding  dividend payment date will receive the dividend payable
by the  Corporation  on such  shares  of  Exchangeable  Preferred  Stock on such
dividend  payment date, and need not include payment of the dividend amount upon
surrender  of  such  shares  for  conversion.  Except  as  provided  above,  the
Corporation shall make no payment or adjustment for accrued and unpaid dividends
on shares  of  Exchangeable  Preferred  Stock,  whether  or not in  arrears,  on
conversion  of such shares or for dividends on the shares of Common Stock issued
upon such conversion.

         As  promptly  as  practicable  after the  surrender  by a holder of the
certificates  for  shares of  Exchangeable  Preferred  Stock as  aforesaid,  the
Corporation  shall issue and shall deliver at the office of the conversion agent
to such holder, or on the holder's written order to the holder's  transferee,  a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable upon the conversion of such shares in accordance with the provisions of
this paragraph (iv), and any fractional interest in respect of a share of Common
Stock arising upon such conversion  shall be settled as provided in subparagraph
(III) of this paragraph (iv).

         Each conversion shall be deemed to have been effected immediately prior
to the close of  business  on the date on which the  certificates  for shares of
Exchangeable  Preferred  Stock  shall  have  been  surrendered  and such  notice
received by the  Corporation  as  aforesaid,  and the person or persons in whose
name or names any certificate or  certificates  for shares of Common Stock shall
be issuable  upon such  conversion  shall be deemed to have become the holder or
holders of record of the shares of Common Stock represented thereby at such time
on such date and such conversion  shall be at the Conversion  Price in effect at
such time on such date, unless the stock transfer books of the Corporation shall
be closed on that date, in which event such person or persons shall be deemed to
have  become  such  holder or holders of record at the close of  business on the
next  succeeding  day on which  such  stock  transfer  books are open,  but such
conversion  shall be at the  Conversion  Price in effect on the date upon  which
shares of  Exchangeable  Preferred  Stock shall have been  surrendered  and such
notice  received by the  Corporation.  All shares of Common Stock delivered upon
conversion of the  Exchangeable  Preferred  Stock will upon delivery be duly and
validly issued and fully paid and non-assessable,  free of all liens and charges
and not subject to any  preemptive  rights.  Upon the surrender of  certificates
representing shares of Exchangeable Preferred Stock, such shares shall no longer
be deemed to be  outstanding  and all  rights of a holder  with  respect to such

                                       10
<PAGE> 

shares  surrendered for conversion shall immediately  terminate except the right
to receive the Common Stock or other securities,  cash or other assets as herein
provided.

                  (III) FRACTIONAL  SHARES.  No fractional  shares or securities
representing  fractional  shares of Common Stock shall be issued upon conversion
of the  Exchangeable  Preferred  Stock.  Any  fractional  interest in a share of
Common Stock  resulting  from  conversion of a share of  Exchangeable  Preferred
Stock shall be paid in cash  (computed  to the  nearest  cent) based on the last
reported sale price of the Common Stock (as defined in  subparagraph  (IV)(d) of
this  paragraph  (iv)) on the business day next preceding the day of conversion.
If more than one share shall be  surrendered  for  conversion at one time by the
same holder,  the number of full shares of Common Stock issuable upon conversion
thereof shall be computed on the basis of the aggregate  Liquidation  Preference
of the shares of Exchangeable Preferred Stock so surrendered.

                  (IV)  ADJUSTMENT.  The Conversion Price shall be adjusted from
time to time as follows:

                           (a)      In case the Corporation shall (i) pay a
dividend  or make a  distribution  on its  Common  Stock in shares of its Common
Stock,  (ii)  subdivide its  outstanding  Common Stock into a greater  number of
shares,  or (iii) combine its outstanding  Common Stock into a smaller number of
shares,  the  Conversion  Price in effect  immediately  prior  thereto  shall be
adjusted  so that the  holder  of any  share  of  Exchangeable  Preferred  Stock
thereafter surrendered for conversion shall be entitled to receive the number of
shares of Common Stock of the Corporation which he would have owned or have been
entitled to receive after the happening of any of the events described above had
such share been converted  immediately  prior to the happening of such event. An
adjustment  made pursuant to this  subparagraph  (IV)(a) shall become  effective
immediately,  except as provided in subparagraph (IV)(g) below, after the record
date in the case of a  dividend  or  distribution  and  shall  become  effective
immediately after the effective date in the case of subdivision or combination.

                           (b)      In case the Corporation shall issue rights
or  warrants  to all holders of its Common  Stock  entitling  them (for a period
expiring within 45 days after the record date mentioned  below) to subscribe for
or purchase Common Stock at a price per share less than the current market price
per share of Common  Stock (as  defined in  subparagraph  (IV)(d)  below) at the
record date for the  determination  of  stockholders  entitled  to receive  such
rights or warrants,  the Conversion  Price in effect  immediately  prior thereto
shall  be  adjusted  so that  the same  shall  equal  the  price  determined  by
multiplying  the  Conversion  Price in effect  immediately  prior to the date of
issuance of such rights or warrants by a fraction of which the  numerator  shall
be the number of shares of Common Stock  outstanding  on the date of issuance of

                                       11
<PAGE>  

such  rights or  warrants  plus the number of shares of Common  Stock  which the
aggregate  offering  price  of  the  total  number  of  shares  so  offered  for
subscription  or purchase would  purchase at such current  market price,  and of
which the denominator  shall be the number of shares of Common Stock outstanding
on the date of issuance of such rights or warrants plus the number of additional
shares of Common Stock offered for  subscription  or purchase.  Such  adjustment
shall be made successively  whenever any such rights or warrants are issued, and
shall become effective  immediately,  except as provided in subparagraph (IV)(g)
below,  after such record date.  In  determining  whether any rights or warrants
entitle the holders of the Common Stock to subscribe  for or purchase  shares of
Common Stock at less than such current  market  price,  and in  determining  the
aggregate  offering price of the shares of Common Stock so offered,  there shall
be taken into account any  consideration  received by the  Corporation  for such
rights or warrants,  the value of such consideration,  if other than cash, to be
determined by the Board of Directors.

                           (c)      In case the Corporation shall distribute to
     all  holders  of its  Common  Stock  any  shares  of  capital  stock of the
Corporation  (other than Common  Stock) or evidences of  indebtedness  or assets
(excluding cash dividends or other  distributions paid from retained earnings of
the  Corporation)  or rights or warrants to subscribe for or purchase any of its
securities (excluding those referred to in subparagraph (IV)(b) above), then, in
each such case,  the  Conversion  Price shall be adjusted so that the same shall
equal  the  price  determined  by  multiplying  the  Conversion  Price in effect
immediately  prior to the date of such  distribution  by a fraction of which the
numerator  shall be the  current  market  price per  share of  Common  Stock (as
defined in  subparagraph  (IV)(d) below) on the record date mentioned below less
the then fair market  value (as  determined  by the Board,  whose  determination
shall, if made in good faith, be conclusive) of the portion of the capital stock
or assets or  evidences  of  indebtedness  so  distributed  or of such rights or
warrants  applicable to one share of Common Stock,  and of which the denominator
shall be the current market price per share (as defined in subparagraph  (IV)(d)
below) of the Common Stock. Such adjustment shall become effective  immediately,
except as provided in subparagraph  (IV)(g) below, after the record date for the
determination of shareholders entitled to receive such distribution.


                           (d)      DEFINITION OF CURRENT MARKET PRICE.  For the
purpose of any  computation  under  subparagraphs  (IV)(b)  and (c)  above,  the
current market price per share of Common Stock at any date shall be deemed to be
the average of the last  reported  sale prices for the ten  consecutive  Trading
Days (as defined below) preceding the day before the record date with respect to
any distribution,  issuance or other event requiring such computation.  The last
reported  sale price for each day shall be (i) the last  reported  sale price of
Common  Stock on the  National  Market  System of the  National  Association  of

                                       12
<PAGE>

Securities  Dealers,  Inc. Automated  Quotation System, or any similar system of
automated  dissemination of quotations of securities  prices then in common use,
if so quoted, or (ii) if not quoted as described in clause (i), the mean between
the high bid and low  asked  quotations  for  Common  Stock as  reported  by the
National  Quotation Bureau  Incorporated if at least two securities dealers have
inserted both bid and asked  quotations for such class of stock on at least five
of the ten  preceding  days,  or (iii) if the Common Stock is listed or admitted
for trading on any national  securities  exchange,  the last sale price,  or the
closing bid price if no sale  occurred,  of such class of stock on the principal
securities  exchange on which such class of stock is listed. If the Common Stock
is quoted on a national securities or central market system, in lieu of a market
or quotation  system  described  above,  the last  reported  sale price shall be
determined in the manner set forth in clause (ii) of the  preceding  sentence if
bid and asked  quotations are reported but actual  transactions  are not, and in
the  manner  set  forth in  clause  (iii) of the  preceding  sentence  if actual
transactions are reported. If none of the conditions set forth above is met, the
last  reported sale price of Common Stock on any day or the average of such last
reported sale prices for any period shall be the fair market value of such class
of stock as  determined  by a member firm of the New York Stock  Exchange,  Inc.
selected by the Company.  As used herein the term "Trading Days" with respect to
Common  Stock  means (i) if the Common  Stock is quoted on the  National  Market
System  of the  National  Association  of  securities  Dealers,  Inc.  Automated
Quotation system or any similar system of automated  dissemination of quotations
of securities  prices,  days on which trades may be made on such system, or (ii)
if not quoted as described in clause (i), days on which  quotations are reported
by the National Quotation Bureau  Incorporated,  or (iii) if the Common Stock is
listed or admitted  for trading on any  national  securities  exchange,  days on
which such national securities exchange is open for business.


                           (e)      No adjustment in the Conversion Price shall
be required unless such adjustment would require a change of at least 1% in such
price;  PROVIDED,  HOWEVER,  that  any  adjustments  which  by  reason  of  this
subparagraph  (IV)(e) are not  required to be made shall be carried  forward and
taken into account in any subsequent  adjustment;  [and provided,  further, that
adjustment  shall be required and made in accordance with the provisions of this
paragraph (iv). All calculations  under this paragraph (iv) shall be made to the
nearest  cent or to the nearest one  hundredth  of a share,  as the case may be.
Anything  in  this  subparagraph  (IV)  to  the  contrary  notwithstanding,  the
Corporation  shall be entitled to make such reductions in the Conversion  Price,
in addition to those required by this subparagraph (IV), as it in its discretion
shall determine to be advisable in order that any stock  dividends,  subdivision
or combination of shares, distribution of capital stock or rights or warrants to
purchase stock or securities,  or  distribution  of evidences of indebtedness or

                                       13
<PAGE>

assets (other than cash dividends or distributions  paid from retained earnings)
hereafter made by the Corporation to its stockholders shall not be taxable.

                           (f)  NOTICE OF ADJUSTMENT.  Whenever the Conversion 
Price is adjusted, as herein provided,  the Corporation shall promptly file with
the conversion agent an officers' certificate setting forth the Conversion Price
after such adjustment and setting forth a brief statement of the facts requiring
such  adjustment,   which  certificate  shall  be  conclusive  evidence  of  the
correctness of such adjustment. Promptly after delivery of such certificate, the
Corporation  shall prepare a notice of such  adjustment of the Conversion  Price
setting  forth  the  adjusted  Conversion  Price  and  the  date on  which  such
adjustment  becomes  effective and shall mail such notice of such  adjustment of
the Conversion Price to the holder of each share of Exchangeable Preferred Stock
at his last address as shown on the stock books of the Corporation.

                           (g)      In any case in which this subparagraph (IV)
provides that an adjustment  shall become effective  immediately  after a record
date for an event,  the Corporation may defer until the occurrence of such event
(i) issuing to the holder of any share of Exchangeable Preferred Stock converted
after such record date and before the  occurrence  of such event the  additional
shares of Common Stock issuable upon such conversion by reason of the adjustment
required  by such  event  over and above the  Common  Stock  issuable  upon such
conversion  before  giving  effect to such  adjustment  and (ii)  paying to such
holder any amount in cash in lieu of any fraction pursuant to subparagraph (III)
of this paragraph (iv).

                  (V)      If:

                           (a)      the Corporation shall declare a dividend (or
any other  distribution) on the Common Stock (other than in cash out of retained
earnings); or

                           (b)      the Corporation shall authorize the granting
to the holders of the Common  Stock of rights or warrants  to  subscribe  for or
purchase any shares of any class or any other rights or warrants; or

                           (c)      there shall be any reclassification of the 
Common Stock (other than a subdivision or combination of the outstanding  Common
Stock and  other  than a change  in the par  value,  or from par value to no par
value,  or from no par value to par value),  or any  consolidation,  merger,  or
statutory  share  exchange  to which  the  Corporation  is a party and for which
approval of any  stockholders  of the  Corporation  is required,  or any sale or
transfer of all or substantially all the assets of the Corporation or any Change
in Control (as defined in paragraph (ix) below); or
 
                                       14
<PAGE> 


                           (d)      there shall be a voluntary or an involuntary
dissolution, liquidation or winding up of the Corporation;

then the  Corporation  shall cause to be filed with the  conversion  agent,  and
shall cause to be mailed to the holders of shares of the Exchangeable  Preferred
Stock at their  addresses  as shown on the stock  books of the  Corporation,  at
least 15 days  prior to the  applicable  date  hereinafter  specified,  a notice
stating  (i) the date on which a record is to be taken for the  purpose  of such
dividend,  distribution  or  rights  or  warrants,  or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such  dividend,  distribution  or rights or warrants are to be  determined or
(ii) the date on which such reclassification,  consolidation,  merger, statutory
share exchange, sale, transfer, Change in Control,  dissolution,  liquidation or
winding  up is  expected  to  become  effective,  and the date as of which it is
expected  that  holders of Common  Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property  deliverable  upon
such reclassification,  consolidation,  merger,  statutory share exchange, sale,
transfer, Change in Control, dissolution,  liquidation or winding up. Failure to
give such notice or any defect therein shall not affect the legality or validity
of the proceedings described in subparagraph (VIII) of this paragraph (iv) or in
subparagraph (V)(a), (V)(b), (V)(c) or (V)(d) of this paragraph (iv).

                  (VI)  RESERVATION OF COMMON STOCK.  The Corporation  covenants
that it will at all times  reserve  and keep  available,  free  from  preemptive
rights,  out of the aggregate of its  authorized  but unissued  shares of Common
Stock or its issued  shares of Common Stock held in its treasury,  or both,  for
the purpose of effecting  conversions of the  Exchangeable  Preferred Stock, the
full number of shares of Common Stock  deliverable  upon the  conversion  of all
outstanding  shares of Exchangeable  Preferred Stock not theretofore  converted.
For  purposes of this  subparagraph  (VI),  the number of shares of Common Stock
which shall be  deliverable  upon the  conversion of all  outstanding  shares of
Exchangeable  Preferred Stock shall be computed as if at the time of computation
all such outstanding shares were held by a single holder.

         Before taking any action which would cause an  adjustment  reducing the
Conversion Price below the then par value (if any) of the shares of Common Stock
deliverable upon conversion of the Exchangeable Preferred Stock, the Corporation
will take any  corporate  action  which may, in the opinion of its  counsel,  be
necessary in order that the Corporation may validly and legally issue fully paid
and non-assessable shares of Common Stock at such adjusted Conversion Price.

         The  Corporation  will  endeavor  to list the  shares of  Common  Stock
required to be delivered upon  conversion of the  Exchangeable  Preferred  Stock

                                       15
<PAGE>  
 
prior to such  delivery  upon each national  securities  exchange,  if any, upon
which the outstanding Common Stock is listed at the time of such delivery.

         Prior to the delivery of any securities which the Corporation  shall be
obligated to deliver upon conversion of the  Exchangeable  Preferred  Stock, the
Corporation  will  endeavor  to  comply  with all  federal  and  state  laws and
regulations  thereunder  requiring the  registration of such securities with, or
any  approval  of or  consent  to the  delivery  thereof  by,  any  governmental
authority.

                  (VII) TAXES.  The Corporation will pay any and all documentary
stamp or  similar  issue or  transfer  taxes  payable in respect of the issue or
delivery of shares of Common Stock on conversion of the  Exchangeable  Preferred
Stock pursuant  hereto;  PROVIDED,  HOWEVER,  that the Corporation  shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issue or delivery of shares of Common  Stock in a name other than that of
the holder of the Exchangeable Preferred Stock to be converted and no such issue
or delivery shall be made unless and until the person  requesting  such issue or
delivery  has  paid  to  the  Corporation  the  amount  of any  such  tax or has
established,  to the  satisfaction  of the  Corporation,  that such tax has been
paid.

                  (VIII)  MERGERS  OR  OTHER   COMBINATIONS.   In  case  of  any
reclassification  or change of outstanding  shares of Common Stock (other than a
change in par value, or as a result of a subdivision or combination), or in case
of any  consolidation of the Corporation with, or merger of the Corporation with
or into,  any other Person,  any merger of another  Person into the  Corporation
(other  than a merger  which  does not  result  in a  reclassification,  change,
conversion,  exchange or cancellation of outstanding  shares of Common Stock) or
any  sale  or  transfer  of  all or  substantially  all  of  the  assets  of the
Corporation,  the  holder of each  share of  Exchangeable  Preferred  Stock then
outstanding   shall  have  the  right   thereafter  to  convert  such  share  of
Exchangeable  Preferred  Stock into the kind and amount of securities,  cash and
other  property  which the holder would have been  entitled to receive upon such
reclassification,  change, consolidation, merger, sale or transfer if the holder
had  held  the  Common  Stock  issuable  upon the  conversion  of such  share of
Exchangeable Preferred Stock immediately prior to such reclassification, change,
consolidation, merger, sale or transfer, assuming such holder of Common Stock of
the Corporation  (i) is not a Person with which the Corporation  consolidated or
into which the  Corporation  merged or which merged into the  Corporation  or to
which such sale or transfer was made, as the case may be ("constituent Person"),
or an Affiliate of a  constituent  Person and (ii) failed to exercise any rights
of  election  as to the kind or amount of  securities,  cash and other  property
receivable upon such reclassification,  change,  consolidation,  merger, sale or
transfer  (provided,  that if the kind or amount of  securities,  cash and other

                                       16
<PAGE>

property receivable upon such reclassification,  change, consolidation,  merger,
sale or  transfer  is not the  same  for  each  share  of  Common  Stock  of the
Corporation   held   immediately   prior  to  such   reclassification,   change,
consolidation, merger, sale or transfer by other than a constituent Person or an
Affiliate thereof and in respect of which such rights of election shall not have
been exercised ("non-electing share"), then for the purpose of this subparagraph
VIII the kind and amount of securities,  cash and other property receivable upon
such reclassification,  change, consolidation,  merger, sale or transfer by each
non-electing  share shall be deemed to be the kind and amount so receivable  per
share by a plurality of the non-electing  shares).  The above provisions of this
subparagraph  VIII  shall  similarly  apply  to  successive   reclassifications,
changes, consolidations, mergers, sales or transfers.

         (v) STATUS.  Upon any  conversion,  exchange or redemption of shares of
Exchangeable  Preferred  Stock,  the shares of  Exchangeable  Preferred Stock so
converted,  exchanged  or  redeemed  shall  have the  status of  authorized  and
unissued shares of preferred  stock, and the number of shares of preferred stock
which the  Corporation  shall have  authority to issue shall not be decreased by
the  conversion,  exchange or  redemption  of shares of  Exchangeable  Preferred
Stock.

         (vi) VOTING  RIGHTS.  The holders of shares of  Exchangeable  Preferred
Stock shall have no voting  rights  whatsoever,  except for any voting rights to
which they may be entitled under the laws of the State of Washington, and except
as follows:

                  (I) If and whenever at any time or times dividends  payable on
the  Exchangeable  Preferred Stock or Parity  Preferred Stock shall have been in
arrears and unpaid in an aggregate  amount  equal to or exceeding  the amount of
dividends  payable thereon for three  semi-annual  periods,  then the holders of
such  Exchangeable  Preferred  Stock and Parity  Preferred  Stock having similar
voting  rights then  exercisable  shall have the  exclusive  right,  voting as a
single  class  without  regard  to  series,   to  elect  two  directors  of  the
Corporation,  such  directors  to be in  addition  to the  number  of  directors
constituting  the Board of  Directors  immediately  prior to the accrual of such
right.  The  remaining  directors  shall  be  elected  in  accordance  with  the
provisions of the Corporation's Restated Articles of Incorporation and Bylaws by
the other class or classes of stock entitled to vote therefor at each meeting of
stockholders  held for the purpose of electing  directors.  Such voting right of
the  Exchangeable  Preferred  Stock  shall  continue  until  such  time  as  all
cumulative dividends accumulated on the Exchangeable  Preferred Stock and Parity
Preferred  Stock  having  cumulative  dividends  shall have been paid in full at
which time such voting right of the holders of the Exchangeable  Preferred Stock
shall terminate,  subject to revesting in the event of each and every subsequent
event of default of the character indicated above.

                                       17
<PAGE> 


         Whenever  such  voting  right  shall  have  vested,  such  right may be
exercised  initially  either  at  a  special  meeting  of  the  holders  of  the
Exchangeable  Preferred  Stock and Parity  Preferred Stock having similar voting
rights  then  exercisable,  called as  hereinafter  provided,  or at any  annual
meeting  of  stockholders  held  for the  purpose  of  electing  directors,  and
thereafter at each successive annual meeting.

         At any time when such voting  right shall have vested in the holders of
the Exchangeable  Preferred Stock, and if such right shall not already have been
initially exercised, a proper officer of the Corporation shall, upon the written
request of the holders of record of 10% in number of shares of the  Exchangeable
Preferred Stock then outstanding, addressed to the Secretary of the Corporation,
call a special  meeting of the holders of the  Exchangeable  Preferred Stock and
Parity  Preferred  Stock having similar voting rights then  exercisable  for the
purpose  of  electing  directors.  Such  meeting  shall be held at the  earliest
practicable date upon the notice required for annual meetings of stockholders at
the place for holding of annual meetings of stockholders of the Corporation, or,
if none,  at a place  designated by the  Secretary of the  Corporation.  If such
meeting shall not be called by the proper officers of the Corporation  within 30
days after the personal  service of such written  request upon the  Secretary of
the  Corporation,  or within 30 days after  mailing  the same  within the United
States of  America,  by  registered  mail,  addressed  to the  Secretary  of the
Corporation  at its  principal  office  (such  mailing  to be  evidenced  by the
registry receipt issued by the postal  authorities),  then the holders of record
of 10% in number of shares of the Exchangeable  Preferred Stock then outstanding
may designate in writing one of their number to call such meeting at the expense
of the Corporation,  and such meeting may be called by such person so designated
upon the notice required for annual  meetings of stockholders  and shall be held
at the same place as is  elsewhere  provided for in this  subparagraph  (I). Any
holder of the Exchangeable  Preferred Stock shall have access to the stock books
of the  Corporation  for the purpose of causing a meeting of  stockholders to be
called  pursuant  to the  provisions  of  this  paragraph.  Notwithstanding  the
provisions of this paragraph,  however,  no such special meeting shall be called
during a period within 90 days immediately preceding the date fixed for the next
annual meeting of stockholders.

         At any meeting held for the purpose of electing  directors at which the
holders  of the  Exchangeable  Preferred  Stock  shall  have the  right to elect
directors as provided herein,  the presence in person or by proxy of the holders
of 33-1/3% of the then outstanding  shares of the  Exchangeable  Preferred Stock
and Parity Preferred Stock having similar voting rights then  exercisable  shall
be required and be sufficient to constitute a quorum of such preferred stock for
the  election of  directors  by such  preferred  stock.  At any such  meeting or
adjournment  thereof  (A)  the  absence  of a  quorum  of  the  holders  of  the
Exchangeable  Preferred  Stock and Parity  Preferred Stock having similar voting

                                       18
<PAGE> 

rights then  exercisable  shall not prevent the election of directors other than
those to be elected by the holders of such preferred stock, and the absence of a
quorum or quorums of the  holders  of other  classes or series of capital  stock
entitled  to elect  such other  directors  shall not  prevent  the  election  of
directors to be elected by the holders of the  Exchangeable  Preferred Stock and
Parity Preferred Stock having similar voting rights then exercisable, and (B) in
the  absence of a quorum of the  holders  of  Exchangeable  Preferred  Stock and
Parity Preferred Stock having similar voting rights then exercisable, a majority
of the holders  present in person or by proxy of such preferred stock shall have
the power to adjourn  the  meeting,  or  appropriate  portion  thereof,  for the
election of directors  which the holders of such preferred stock are entitled to
elect, from time to time, without notice other than announcement at the meeting,
until a quorum shall be present.

         The directors  elected  pursuant to this  subparagraph  (I) shall serve
until the next annual  meeting or until  their  respective  successors  shall be
elected and shall qualify; PROVIDED, HOWEVER, that when the right of the holders
of the Exchangeable  Preferred Stock to elect directors as herein provided shall
terminate,  the terms of office of all  persons so elected by the holders of the
Exchangeable Preferred Stock shall terminate, and the number of directors of the
Corporation shall thereupon be such number as may be provided in accordance with
the  Restated   Articles  of  Incorporation   and  Bylaws  of  the  Corporations
irrespective of any increase made pursuant to this subparagraph (I).

         So long as any shares of Exchangeable  Preferred Stock are outstanding,
the  Restated  Articles of  Incorporation  and Bylaws of the  Corporation  shall
contain  provisions  ensuring  that the number of Directors  of the  Corporation
shall at all  times be such  that the  exercise  by the  holders  of  shares  of
Exchangeable  Preferred  Stock  of  the  right  to  elect  Directors  under  the
circumstances  provided  in  this  subparagraph  (I)  will  not  contravene  any
provisions of the Corporation's Restated Articles of Incorporation or Bylaws.

                  (II) So long as any shares of the Exchangeable Preferred Stock
remain  outstanding,  the Corporation will not, either directly or indirectly or
through  merger  or  consolidation  with  any  other  corporation,  without  the
affirmative  vote at a meeting or the written  consent with or without a meeting
of the  holders  of at least  66-2/3%  in number  of shares of the  Exchangeable
Preferred Stock then  outstanding,  (A) create any class or classes or series of
stock ranking prior to, or on a parity with, the  Exchangeable  Preferred  Stock
either as to dividends or upon liquidation or increase the authorized  number of
shares of any class or  classes  or  series of stock  ranking  prior to, or on a
parity with,  the  Exchangeable  Preferred  Stock either as to dividends or upon
liquidation,  (B) amend,  alter or repeal any of the  provisions of the Restated

                                       19
<PAGE> 

Articles of  Incorporation  (including this Statement of Rights and Preferences)
so as to  affect  adversely  the  preferences,  special  rights or powers of the
Exchangeable   Preferred  Stock,  (C)  authorize  any  reclassification  of  the
Exchangeable  Preferred  Stock or (D) incur or suffer to exist any Debt that, by
its terms or the terms of the  instrument  creating  or  evidencing  it, is pari
passu  with or  subordinate  in  right  of  payment  to the  9-3/4%  Convertible
Subordinated  Debentures  due  2014  issued  by the  Company  in May 1989 or the
Debentures  described  in  paragraph  (vii)  herein.  "Debt"  shall mean (i) all
indebtedness and other  obligations for the payment of money of the Corporation,
whenever  created,  incurred,  or  assumed,  which  is (a) for  borrowed  money,
evidenced  by a note or  similar  instrument,  or (b) for the  payment  of money
relating to (x) any obligations of the Corporation as lessee under leases of any
type of property  required to be  capitalized on the balance sheet of the lessee
under generally accepted accounting  principles and leases of property or assets
made as part of any sale and lease-back  transaction to which the Corporation is
a party or (y) any other  agreement to lease,  or lease of, any real or personal
property or mixture  thereof,  or (c) evidenced by a note or similar  instrument
given by the  Corporation in connection  with the acquisition by the Corporation
or any subsidiary of any businesses, properties or assets of any kind other than
trade accounts payable or accrued  liabilities arising in the ordinary course of
business, or (d) arising from letters of credit, bankers' acceptances,  currency
agreements or interest rate swaps, or (e) relating to performance, completion or
similar bonds of the Corporation;  (ii) any liability of others described in the
preceding  clause which the Corporation has guaranteed or which is otherwise its
legal liability; and (iii) any modification,  amendment,  renewal,  extension or
refunding of any such indebtedness or obligation.

         (vii)  EXCHANGE.  The  Exchangeable  Preferred Stock is exchangeable in
whole at the option of the  Corporation  on any dividend  payment date beginning
June 1, 1992, for the Corporation's 9-3/4% Convertible  Subordinated  Debentures
due 2014 (the  "Debentures")  as  described  in the  Corporation's  Registration
Statement on Form S-4, as amended (Registration No. 33-33152), as filed with the
Securities  and  Exchange   Commission.   Holders  of   outstanding   shares  of
Exchangeable Preferred Stock will be entitled to receive $25.00 principal amount
of Debentures in exchange for each share of Exchangeable Preferred Stock held by
them at the time of exchange;  PROVIDED that the Debentures  will be issuable in
denominations  of $25.00 and integral  multiples  thereof.  The Corporation will
mail to each record holder of the Exchangeable Preferred Stock written notice of
its  intention  to exchange  not less than 30 nor more than 60 days prior to the
date of exchange (the "Exchange  Date").  The notice shall specify the effective
date of the exchange and the place where certificates for shares of Exchangeable
Preferred  Stock are to be  surrendered  for  Debentures  and shall  state  that
dividends on  Exchangeable  Preferred Stock will cease to accrue on such date of
exchange. Prior to giving notice of intention to exchange, the Corporation shall

                                       20
<PAGE>

execute and deliver with a bank or trust company  selected by the Corporation an
Indenture  substantially  in the form filed as an  Exhibit to such  Registration
Statement  with such changes as may be required by law,  stock  exchange rule or
usage.  The  Corporation  will cause the Debentures to be  authenticated  on the
Exchange Date; at such time the rights of the holders of Exchangeable  Preferred
Stock as  stockholders  of the  Corporation  shall  cease  (except  the right to
receive  accumulated and unpaid  dividends to the Exchange Date) and such shares
of Exchangeable  Preferred Stock shall no longer be deemed outstanding and shall
represent  only the right to receive the  Debentures  and such  accumulated  and
unpaid dividends.  Notwithstanding the foregoing, if notice of exchange has been
given pursuant to this paragraph  (vii) and any holder of shares of Exchangeable
Preferred Stock shall, prior to the close of business on the Exchange Date, give
written notice to the  Corporation  pursuant to paragraph (iv) of the conversion
of any or all of the shares held by such holder (accompanied by a certificate or
certificates  for such shares,  duly  endorsed or assigned to the  Corporation),
then such exchange shall not become  effective as to such shares to be converted
and such  conversion  shall become  effective as provided in paragraph (iv). The
Debentures will be delivered to the persons  entitled  thereto upon surrender to
the Corporation or its agent appointed for that purpose of the  certificates for
the shares of  Exchangeable  Preferred Stock being  exchanged  therefor.  If the
Corporation has not paid full cumulative dividends on the Exchangeable Preferred
Stock to the Exchange Date (or set aside a sum therefor) the Corporation may not
exercise its option to exchange the  Debentures for the  Exchangeable  Preferred
Stock.

         (viii)  REDEMPTION BY THE  CORPORATION.  The shares of the Exchangeable
Preferred Stock may be redeemed at the option of the Corporation, as a whole, or
from time to time,  in part,  upon not less than 30 nor more than 60 days' prior
notice mailed to the holders of the shares to be redeemed at their  addresses as
shown on the stock books of the Corporation,  at the following redemption prices
per share during the 12-month period beginning June 1:
<TABLE>
<CAPTION>

YEAR     REDEMPTION PRICE       YEAR                    REDEMPTION PRICE
- ----     ----------------       ----                    ----------------
<S>      <C>                    <C>                     <C>

1990     27.19375               1996                    25.73125
1991     26.95000               1997                    25.48750
1992     26.70625               1998                    25.24375
1993     26.46250               1999 and thereafter     25.00000
1994     26.21875
</TABLE>

together  in each case with an amount  equal to all  dividends  accumulated  and
unpaid to the date fixed for redemption;  PROVIDED that no such redemption shall
be effected on or before June 1, 1992 unless (i) the last reported sale price of

                                       21
<PAGE>

the Common Stock, as determined in subparagraph  (iv)(IV)(d)  herein,  equals or
exceeds  150% of the  conversion  price for at least 20  Trading  Days  within a
period of 30  consecutive  Trading Days ending within five Trading Days prior to
the  date on  which  the  notice  of  redemption  is  first  mailed  or (ii) the
redemption  is effected in  connection  with certain  circumstances  involving a
Change in Control (as defined  below).  If the  Exchangeable  Preferred Stock is
redeemed in connection with certain circumstances  involving a Change in Control
prior to June 1, 1992 then,  in  addition  to the  amounts  payable as set forth
above, the holders of redeemed shares of Exchangeable Preferred Stock shall also
receive as an  additional  premium an amount equal to the  dividends  they would
have received on the shares of  Exchangeable  Preferred Stock redeemed from, and
including,  the date of  redemption  to June 1, 1992.  For the  purposes of this
paragraph  (viii), a "Change in Control" of the Corporation  shall have the same
meaning as applicable  to the holder's  optional  repurchase  right set forth in
paragraph (ix)(ii)(f) hereof, except that the proviso shall not apply.

         If full cumulative  dividends on the Exchangeable  Preferred Stock have
not been paid, the Exchangeable  Preferred Stock may not be redeemed in part and
the  Corporation  may not  purchase  or acquire  any shares of the  Exchangeable
Preferred  Stock otherwise than pursuant to a purchase or exchange offer made on
the same terms to all holders of the Exchangeable  Preferred Stock. If less than
all the outstanding  shares of Exchangeable  Preferred Stock are to be redeemed,
the  Corporation  will select  those to be  redeemed  by lot or a  substantially
equivalent method.

         If a notice of  redemption  has been given  pursuant to this  paragraph
(viii) and if, on or before the date fixed for  redemption,  the funds necessary
for such redemption shall have been set aside by the  Corporation,  separate and
apart from its other funds,  in trust for the pro rata benefit of the holders of
the shares so called for redemption, then, notwithstanding that any certificates
for such shares have not been  surrendered for  cancellation,  on the redemption
date  dividends  shall cease to accrue on the shares of  Exchangeable  Preferred
Stock to be redeemed,  and at the close of business on the  redemption  date the
holders of such  shares  shall  cease to be  stockholders  with  respect to such
shares and shall have no interest in or claims against the Corporation by virtue
thereof and shall have no voting or other  rights with  respect to such  shares,
except the right to receive  the moneys  payable  upon such  redemption  and the
right to  accumulated  and unpaid  dividends,  without  interest  thereon,  upon
surrender  (and   endorsement,   if  required  by  the   Corporation)  of  their
certificates,  and the  shares  evidenced  thereby  shall no  longer  be  deemed
outstanding.  Notwithstanding  the  foregoing,  if notice of redemption has been
given pursuant to this paragraph (viii) and any holder of shares of Exchangeable
Preferred  Stock  shall,  prior to the close of  business  on the date fixed for

                                       22
<PAGE> 

redemption, give written notice to the Corporation pursuant to paragraph (iv) of
the conversion of any or all of the shares held by such holder (accompanied by a
certificate or  certificates  for such shares,  duly endorsed or assigned to the
Corporation),  then such redemption shall not become effective as to such shares
to be  converted  and such  conversion  shall  become  effective  as provided in
paragraph  (iv).  Subject to applicable  escheat laws, any moneys  necessary for
redemption  set aside by the  Corporation  and unclaimed at the end of two years
from the redemption  date shall revert to the general funds of the  Corporation,
after which  reversion the holders of such shares so called for  redemption  but
not surrendered  shall look only to the general funds of the Corporation for the
payment of the amounts  payable upon such  redemption.  Any interest  accrued on
funds so deposited shall be paid to the Corporation from time to time. Any funds
which have been deposited by the  Corporation,  or on its behalf,  with a paying
agent or segregated and held in trust by the  Corporation  for the redemption of
shares  converted  into  Common  Stock on or prior  to the date  fixed  for such
redemption  shall  (subject to any right of the holder of such shares to receive
the dividend  payable  thereon as provided in paragraph (iv))  immediately  upon
such  conversion be returned to the Corporation or, if then held in trust by the
Corporation, shall be discharged from such trust.

         (ix)  REPURCHASE  BY THE HOLDER.  In the event  that,  prior to June 1,
1994,  there  shall occur a Change in Control  (as  hereinafter  defined) of the
Corporation,  then  each  holder  of a share  of  Exchangeable  Preferred  Stock
("Holder")  shall have the  right,  at such  Holder's  option,  to  require  the
Corporation to repurchase,  and upon the exercise of such right the  Corporation
shall  repurchase,  all or any  part of such  Holder's  shares  of  Exchangeable
Preferred  Stock  that is an  integral  multiple  of  $25.00,  on a date that is
forty-five  days  after  the  date of the  notice  of the  Corporation  provided
pursuant to subparagraph (I) hereof at a repurchase price equal to the aggregate
Liquidation  Preference  of  the  shares  to  be  repurchased,   plus  dividends
accumulated and unpaid to the repurchase date. At the option of the Corporation,
the  repurchase  price  may be paid in cash or by  delivery  of shares of Common
Stock having a fair market value equal to the  repurchase  price,  PROVIDED that
payment may not be made in Common Stock unless at the time of payment such stock
is listed on a national securities exchange or quoted on the automated quotation
system of the National  Association of Securities  Dealers,  Inc.  ("NASDAQ") or
another  comparable  quotation system.  For purposes of this paragraph (ix), the
fair market value of shares of Common Stock shall be equal to 95% of the average
of the last sale  prices,  as computed  under  paragraph  (iv) (IV) (d), of such
Common  Stock  for each of the  five  consecutive  Trading  Days  ending  on and
including the third Trading Day immediately preceding the repurchase date.

                  (I) (a) Unless the Corporation  shall have theretofore  called
for  redemption  all the  outstanding  shares of  Exchangeable  Preferred  Stock

                                       23
<PAGE>

pursuant to paragraph (viii) on or before the thirtieth day after the occurrence
of a Change in Control,  the Corporation or, at the request of the  Corporation,
the paying,  or transfer agent, if any, shall mail a notice of the occurrence of
the Change in Control and of the repurchase  right set forth herein arising as a
result  thereof  at least  thirty and not more than sixty days prior to the date
fixed for repurchase to the Holders of shares of Exchangeable Preferred Stock so
to be  repurchased  at their last  addresses  as the same appear on the registry
books of the Company.  Such mailing shall be by first class mail.  The notice if
mailed in the manner herein provided shall be conclusively presumed to have been
duly given,  whether or not the Holder  receives  such notice.  The  Corporation
shall also deliver a copy of such notice of a repurchase right to the paying, or
transfer  agent,  if any,  and cause a copy of such notice to be  published in a
newspaper of general  circulation  in the Borough of Manhattan,  The City of New
York.

         Each notice of a repurchase right shall state:

         (l)      the repurchase date,

         (2)      the date by which the repurchase right must be exercised,

         (3)      the repurchase price,

         (4)      a description of the procedure which a Holder of Exchangeable
Preferred Stock must follow to exercise a repurchase right, and

         (5) the Conversion Price then in effect, the date on which the right to
convert  the  shares of  Exchangeable  Preferred  Stock to be  repurchased  will
terminate  and the place or places where such shares of  Exchangeable  Preferred
Stock may be surrendered for conversion.

         In addition,  at least two Trading Days preceding the repurchase  date,
the  Corporation  shall  cause  to  be  published,  in a  newspaper  of  general
circulation  in the  Borough  of  Manhattan,  The  City of New  York,  a  notice
specifying  whether the repurchase price will be payable in cash or in shares of
Common Stock.

         No failure of the  Corporation to give the foregoing  notices or defect
therein shall limit any Holder's right to exercise a repurchase  right or affect
the validity of the proceedings for the repurchase of the shares of Exchangeable
Preferred Stock.

                           (b)      To exercise a repurchase right, a Holder
shall deliver to the Corporation or the paying or transfer agent, if any, as the
case may be, on or before the  thirtieth day after the date of the notice by the
Corporation of a repurchase  right (i) written notice of such Holder's  exercise

                                       24
<PAGE> 
 
of such  right,  which  notice  shall  set  forth  the name of the  Holder,  the
aggregate  Liquidation  Preference of the shares to be repurchased,  a statement
that an election to exercise the repurchase right is being made thereby, and, in
the event that the repurchase price shall be paid in shares of Common Stock, the
name or names (with  addresses) in which the  certificate  or  certificates  for
shares of Common  Stock  shall be issued,  and (ii) the  shares of  Exchangeable
Preferred Stock with respect to which the repurchase  right is being  exercised,
duly  endorsed for  transfer to the  Corporation.  Such written  notice shall be
irrevocable,  except  that the right of the  Holder  to  convert  the  shares of
Exchangeable Preferred Stock with respect to which the repurchase right is being
exercised shall continue until the close of business on the repurchase  date. If
the  repurchase  date falls  during the period from the close of business on any
dividend  payment record date preceding any dividend payment date to the opening
of business on such dividend payment date, the shares of Exchangeable  Preferred
Stock to be  repurchased  must be  accompanied  by payment in New York  Clearing
House or  other  funds  acceptable  to the  Company  of an  amount  equal to the
dividend  payable on such  dividend  payment  date on the number of shares being
repurchased and, notwithstanding such repurchase,  such dividend payment will be
made by the Company to the holder of such share on such dividend  payment record
date. Promptly thereafter,  the paying, or transfer agent, if any, shall deliver
to the Corporation written notice of the aggregate Liquidation Preference of the
shares to be  repurchased,  the name of each Holder who exercised the repurchase
right and the aggregate Liquidation Preference to be repurchased with respect to
each such Holder.

                           (c)     Upon receipt of the notice from the paying or
transfer agent, if any, or upon notice from each Holder, as the case may be, and
as described in subparagraph  (I), the Corporation shall pay or cause to be paid
the repurchase  price in cash or shares of Common Stock,  as provided  above, to
the  Holders  on the  repurchase  date,  together  with  accumulated  and unpaid
dividends  to  the  repurchase  date  payable  with  respect  to the  shares  of
Exchangeable  Preferred  Stock  as  to  which  the  repurchase  right  has  been
exercised.

                           (d)      Any issuance of shares of Common Stock in
respect  of  the  repurchase  price  shall  be  deemed  to  have  been  effected
immediately prior to the close of business on the repurchase date and the Person
or Persons in whose name or names any certificate or certificates  for shares of
Common  Stock shall be  issuable  upon such  repurchase  shall be deemed to have
become on the  repurchase  date the  holder or  holders  of record of the shares
represented  thereby,  PROVIDED that any surrender for repurchase on a date when
the stock transfer books of the Corporation shall be closed shall constitute the
Person or Persons in whose name or names the  certificate  or  certificates  for
such  shares are to be issued as the  recordholder  or holders  thereof  for all
purposes at the opening of  business  on the next  succeeding  day on which such

                                       25
<PAGE> 

stock  transfer  books are open.  No  payment  or  adjustment  shall be made for
dividends or  distributions  on any Common Stock issued upon  conversion  of any
share of Exchangeable Preferred Stock.

                           (e)     No fractions of shares or script representing
fractions of shares shall be issued upon  repurchase  of shares of  Exchangeable
Preferred  Stock.  If more than one  share  shall be  repurchased  from the same
Holder and the repurchase  price shall be payable in shares of Common Stock, the
number of full  shares  which shall be issuable  upon such  repurchase  shall be
computed on the basis of the aggregate  Liquidation  Preference of the shares so
repurchased.  Instead  of any  fractional  share of  Common  Stock  which  would
otherwise be issuable on the repurchase of any share or shares,  the Corporation
shall make payment in lieu thereof in an amount of United  States  dollars equal
to the value of such  fraction  computed  on the basis of the last sale price of
the Common Stock on the last Trading Day prior to the repurchase date.

                           (f      Any issuance and delivery of certificates for
shares of Common Stock on repurchase of shares of  Exchangeable  Preferred Stock
shall be made without charge to the holder of shares being  repurchased for such
certificates  or for any tax or duty in respect of the  issuance  or delivery of
such  certificates  or the  securities  represented  thereby,  PROVIDED that the
Corporation shall not be required to pay any tax or duty which may be payable in
respect of any transfer  involved in the issue or delivery of  certificates  for
shares of Common  Stock in a name other than that of the holder of the shares of
Exchangeable  Preferred Stock being  repurchased,  and no such issue or delivery
shall be made unless and until the Person  requesting such issue or delivery has
paid to the Corporation  the amount of any such tax or duty or has  established,
to the satisfaction of the Corporation, that such tax or duty has been paid.

                           (g)   If any shares of Common Stock to be issued upon
repurchase  of  shares  of  Exchangeable   Preferred  Stock  hereunder   require
registration with or approval of any governmental authority under any federal or
state law before such shares may be validly issued or delivered upon repurchase,
the  Corporation  covenants that it will in good faith and as  expeditiously  as
possible endeavor to secure such  registration or approval,  as the case may be,
PROVIDED  that nothing in this subpart  shall be deemed to affect in any way the
obligations of the  Corporation to repurchase  Exchangeable  Preferred  Stock as
provided in this paragraph (ix).

                           (h)      The Corporation covenants that any shares of
Common Stock which may be issued upon repurchase of Exchangeable Preferred Stock
will be issued from its  authorized  but unissued  shares and upon issue will be
duly and validly issued and fully paid and non-assessable by the Corporation and
free of  preemptive  rights  and that the  shares of Common  Stock  which may be
issued upon repurchase of shares of Exchangeable  Preferred Stock will be listed

                                       26
<PAGE> 

on any national  securities  exchange on which the  outstanding  Common Stock is
listed at the time of such issuance.

                           (i)      If any share of Exchangeable Preferred Stock
surrendered  for  repurchase  shall not be so paid on the  repurchase  date, the
Liquidation  Preference  of such share shall,  until paid,  bear interest to the
extent  permitted by applicable law from the repurchase date at 9-3/4% per annum
and such share of  Exchangeable  Preferred Stock shall remain  convertible  into
Common Stock until the principal of such share of  Exchangeable  Preferred Stock
shall have been paid or duly provided for.

                  (II)     For purposes of paragraph (ix):

                           (a)    The term "Person" shall mean a corporation, an
association,  a partnership,  an organization,  an individual, a government or a
political subdivision thereof or a governmental agency.

                           (b)      The term "Subsidiary" shall mean a corpora-
tion more than 50% of the outstanding  voting stock of which is owned,  directly
or indirectly,  by the Corporation or by one or more other  Subsidiaries,  or by
the  Corporation  and one or more other  Subsidiaries.  For the purposes of this
definition, "voting stock" means stock which ordinarily has voting power for the
election of  directors,  whether at all times or only so long as no senior class
of stock has such voting power by reason of any contingency.

                           (c)      The term "Affiliate" of any specified Person
shall mean any other Person directly or indirectly  controlling or controlled by
or under direct or indirect common control with such specified  Person.  For the
purposes of this  definition,  "control" when used with respect to any specified
Person  means  power to direct  the  management  and  policies  of such  Person,
directly or  indirectly,  whether  through  ownership of voting  securities,  by
contract  or  otherwise;  and the  terms  "controlling"  and  "controlled"  have
meanings correlative to the foregoing.

                           (d)     the term "Associate" of any Person, means (1)
any corporation or  organization  (other than the Corporation or a Subsidiary of
the Corporation or any Person  controlled  directly or indirectly (as defined in
the  definition of Affiliate  above) by the  Corporation  or a Subsidiary of the
Corporation)  of which  such  Person is an  officer  or  general  partner or is,
directly or indirectly, the beneficial owner of ten percent or more of any class
of equity securities,  (2) any trust or other estate in which such Person serves
as trustee or in a similar fiduciary capacity, and (3) any relative or spouse of
such  Person,  or any  relative  of such  spouse,  who has the same home as such
Person or who is a director or officer of the  Corporation or any of its parents
or Subsidiaries;

                                       27
<PAGE> 

                           (e)      the term "beneficial owner" shall be deter-
mined in accordance with Rule 13d-3  promulgated  under the Securities  Exchange
Act of 1934,  as  amended,  as in  effect on the date of  effectiveness  of this
Statement of Rights and Preferences; and

                           (f)      a "Change in Control" of the Corporation
shall be deemed to have  occurred  at such time as any Person is or becomes  the
beneficial owner,  directly or indirectly,  through a purchase,  merger or other
acquisition transaction or series of transactions, of shares of capital stock of
the Corporation  entitling such Person to exercise  seventy-five percent or more
of the total  voting  power of all  shares of capital  stock of the  Corporation
entitled to vote in elections of  directors;  PROVIDED  that a Change in Control
shall not be deemed to have  occurred  if either  (i) the last sale price of the
Common  Stock  on any  five  Trading  Days  during  the 10  Trading  Day  period
immediately  preceding  the date of the Change in Control  shall equal or exceed
105% of the  conversion  price in effect on such  Trading Day or (ii) all of the
consideration (excluding cash payments for fractional shares) to be paid for the
Common  Stock in the  transaction  or  transactions  constituting  the Change in
Control  consists  of shares of common  stock  traded on a  national  securities
exchange or through NASDAQ or another comparable quotation system.

         (x) CONSENT.  Subject to the provisions set forth in paragraph (vi), no
consent of the holders of the Exchangeable Preferred Stock shall be required for
(a) the creation of any  indebtedness  of any kind of the  Corporation,  (b) the
creation, or increase or decrease in the amount, of any class or series of stock
of the Corporation  not ranking prior to, or on a parity with, the  Exchangeable
Preferred Stock either as to dividends or upon liquidation,  (c) any increase or
decrease in the amount of authorized  Common Stock or any increase,  decrease or
change  in the par  value  thereof  or in any  other  terms  thereof  or (d) the
creation,  or any increase or decrease in the amount,  of  authorized  preferred
stock issuable by the Board of Directors in series.

         (xi) NUMBER OF SHARES OF EXCHANGEABLE  PREFERRED STOCK.  Subject to the
provisions of paragraph (vi) hereof,  the Board reserves the right by subsequent
amendment  of this  resolution  from time to time to increase  or  decrease  the
number of shares which  constitute  the  Exchangeable  Preferred  Stock (but not
below the number of shares  thereof then  outstanding)  and in other respects to
amend this resolution  within the  limitations  provided by law, this resolution
and the Restated Articles of Incorporation.

                       ------------------------------

                   DESIGNATION OF RIGHTS AND PREFERENCES OF
                     SERIES 2 CONVERTIBLE PREFERRED STOCK
                       ------------------------------

         A  series  of  Preferred  Stock  is  hereby   designated  as  Series  2
Convertible  Preferred  Stock which series shall consist of 50,000  shares,  par
value $.02 per share (the  "Series 2 Shares"),  and which shall have the rights,
preferences, privileges and limitations as set forth below:

         (1) DIVIDENDS.  The holders of the Series 2 Shares shall be entitled to
a  dividend  of eight  percent  (8%) per annum of the Stated  Value (as  defined
below),  on a cumulative  basis with  quarterly  compounding  (prorated  for any
portion  of  the  applicable  period  during  which  the  Series  2  Shares  are
outstanding).  Dividends  shall accrue from the date of issuance of the Series 2
Shares and shall be paid on each  Series 2 Share at the time that such  Series 2
Share is  converted  or  redeemed.  Dividends  (including  dividends  payable to
holders  of Series 2 Shares as of the date such  holder  elects to  convert  the
Series 2 Shares into Common Stock as provided in Section 2 below) may be paid at
the Company's  option in cash or Common Stock valued based on the Average Market
Price  (as  defined  below)  of the  Common  Stock  for the  period  of five (5)
consecutive  trading days ending on the trading day before the dividend  payment
dates or the date of conversion  or  redemption,  as the case may be;  PROVIDED,
HOWEVER,  that in no event shall  accrued  dividends be paid in shares of Common
Stock if,  after  giving  effect to such  distribution,  the number of shares of
Common  Stock  beneficially  owned by such  holder and all other  holders  whose
holdings  would be  aggregated  with such  holder for  purposes  of  calculating
beneficial  ownership in accordance with Sections 13(d) and 16 of the Securities
Exchange Act of 1934,  as amended,  and the  regulations  thereunder  ("Sections
13(d) and 16"), including,  without limitation, any person serving as an adviser
to any holder  (collectively,  the  "Related  Persons"),  would  exceed four and
nine-tenths percent (4.9%) of the outstanding shares of Common Stock (calculated
in  accordance  with  Sections  13(d) and 16); cash shall be paid in lieu of any
shares which cannot be issued  pursuant to this  proviso.  The Company shall not
issue any  fraction  of a share of Common  Stock in payment of a  dividend,  but
shall pay cash  therefor.  The  Company  shall,  so long as any of the  Series 2
Shares are  outstanding,  reserve and keep  available out of its  authorized and
unissued Common Stock,  such number of shares of Common Stock as shall from time
to time be sufficient to pay dividends hereunder.  Every reference herein to the
Common Stock of the Company (unless a different intention is expressed) shall be
to the shares of the Common Stock of the Company,  $.02 par value, as such stock

                                       29
<PAGE> 

exists  immediately  after the  issuance  of the  Series 2 Shares  provided  for
hereunder,  or to stock into which such Common Stock may be changed from time to
time thereafter.

         "Average Market Price" of any security for any period shall be computed
as the  arithmetic  average of the closing bid prices for such security for each
trading day in such period on the National  Association  of  Securities  Dealers
Automated  Quotation  National  Market  System  (the  "Nasdaq-NMS"),  or, if the
Nasdaq-NMS  is not the  principal  trading  market  for  such  security,  on the
principal  trading  market  for such  security,  or, if market  value  cannot be
calculated  for such period on any of the foregoing  bases,  the Average  Market
Price shall be the average fair market  value  during such period as  reasonably
determined  in good  faith by the  Board of  Directors  of the  Company  (all as
appropriately  adjusted  for any stock  dividend,  stock split or other  similar
transaction during such period or between the end of such period and the date of
conversion or dividend payment, as applicable).

         (2)  CONVERSION OF SERIES 2 SHARES.  The holders of the Series 2 Shares
shall have the right,  at their  option,  to  convert  the Series 2 Shares  into
shares of Common Stock on the following terms and conditions:

                  (a)(i) Each Series 2 share  shall be  convertible  at any time
after the date of issuance (or, if such Series 2 Share is called for redemption,
at any time up to and  including,  but not after,  the close of  business on the
fifth  full  business  day prior to the date filed for such  redemption,  unless
default  shall be made by the Company in providing  the funds for the payment of
the redemption price),  into fully paid and nonassessable  shares (calculated to
the  nearest  whole  share)  of  Common  Stock  at  the  conversion  price  (the
"Conversion  Price")  in  effect  at  the  time  of  conversion   determined  as
hereinafter  provided;  PROVIDED,  HOWEVER, that in no event shall any holder be
entitled to convert Series 2 Shares if, after giving effect to such  conversion,
the number of shares of Common Stock  beneficially  owned by such holder and all
Related  Persons  would  exceed  four  and  nine-tenths  percent  (4.9%)  of the
outstanding shares of Common Stock (calculated in accordance with Sections 13(d)
and 16).  Each Series 2 Share shall have a value of One Hundred  Dollars  ($100)
(the "Stated Value") for the purpose of such conversion.

                  (ii) Commencing on the later of (A) 180 days after the date of
original issue of Series 2 Shares or (B) 90 days after the effective date of the
Registration  Statement  (the  "Registration  Statement")  filed by the  Company
pursuant  to the  Registration  Rights  Agreement  between  the  Company and the
original  purchasers  of the Series 2 Shares,  the Company may at any time cause
the automatic  conversion of all outstanding Series 2 Shares pursuant to written
notice  to the  holders  given  not less  than 30 days and not more than 60 days
prior to the date fixed in the  notice.  Any and all Series 2 Shares  which have

                                       30
<PAGE>  

not been previously  converted by the holders shall be  automatically  converted
into shares of Common  Stock as provided  in Section  (2)(a)(i)  at the close of
business  on the date fixed in such  notice,  at the  Conversion  Price which is
eighty-three  percent (83%) (the "Conversion  Percentage") of the Average Market
Price for the Common Stock for the five (5) consecutive  trading days ending one
trading day prior to the date of automatic conversion;  provided,  however, that
in no event  shall the  Conversion  Price be an amount more than one hundred ten
percent (110%) of the Average Market Price for the Common Stock for the five (5)
consecutive  trading  days  ending one trading day prior to the date of original
issue of Series 2 Shares. The Conversion Price Floor described in Section (2)(b)
shall  not  be   applicable  to  an  automatic   conversion   pursuant  to  this
Section(2)(a)(ii).

                  (b) The Conversion  Price shall be eighty-three  percent (83%)
of the Average  Market Price for the Common  Stock for the five (5)  consecutive
trading days ending one trading day prior to the date the Conversion  Notice (as
defined  below) is received by the Company,  subject to  adjustment  as provided
herein;  PROVIDED,  HOWEVER, in no event shall the Conversion Price be an amount
less than $4.41 per share of Common Stock (the "Conversion Price Floor") or more
than one hundred ten percent  (110%) of the Average  Market Price for the Common
Stock for the five (5) consecutive  trading days ending one trading day prior to
the issuance of the Series 2 Shares.

                  (c) If the Company  shall  consolidate  with or merge into any
corporation or reclassify its outstanding  shares of Common Stock (other than by
way of  subdivision  or reduction of such shares) (each a "Major  Transaction"),
then each  Series 2 Share shall  thereafter  be  convertible  into the number of
shares of stock or securities  (the  "Resulting  Securities") or property of the
Company,  or of the entity resulting from such consolidation or merger, to which
a holder of the number of shares of Common Stock  delivered  upon  conversion of
such Series 2 Share would have been  entitled upon such Major  Transaction,  had
the holder of such Series 2 Share exercised its right of conversion and had such
Common Stock been issued and  outstanding and had such holder been the holder of
record  of such  Common  Stock at the time of such  Major  Transaction,  and the
Company shall make lawful  provision  therefor as a part of such  consolidation,
merger or reclassification; PROVIDED, HOWEVER, that during the period commencing
on the date of original  issue of Series 2 Shares and ending on the later of (A)
180 days  after  the date of  original  issue of  Series 2 Shares or (B) 90 days
after the effective date of the  Registration  Statement,  the Company shall not
consummate a Major Transaction without the approval of the holders of a majority
of the outstanding Series 2 Shares,  unless (A) the Resulting Securities (or the
securities  into which the  Resulting  Securities  are  immediately  convertible
without the payment of additional  consideration) are, at the date of the giving

                                       31
<PAGE>

of the notice referred to in clause (B) below,  listed or included for quotation
on  NASDAQ-NMS,  the New York Stock Exchange or the American Stock Exchange (and
are, at the date of the giving of such notice,  reasonably  expected to continue
to be so listed or included for  quotation for at least the six (6) month period
subsequent to the closing of the Major  Transaction);  and (B) the Company gives
such holder notice of such Major  Transaction  at least thirty (30) trading days
prior to the closing  thereof  (excluding  any trading days that sales cannot be
made pursuant to the Registration Statement for any reason); PROVIDED,  FURTHER,
that in any event the  Company  shall  give the  holders  of the Series 2 Shares
written  notice of any  Major  Transaction  not less  than 30 days  prior to its
consummation.

                  (d) The  Company  shall not issue any  fraction  of a share of
Common Stock upon any conversion,  but shall pay cash therefor at the Conversion
Price then in effect multiplied by such fraction.

                  (e) On  presentation  and  surrender to the Company (or at any
office or agency  maintained  for the  transfer  of the  Series 2 Shares) of the
certificates  of Series 2 Shares so to be converted,  duly endorsed in blank for
transfer or accompanied by proper instruments of assignment or transfer in blank
(a "Conversion Notice"), with signatures guaranteed, the holder of such Series 2
Shares  shall be  entitled,  subject to the  limitations  herein  contained,  to
receive in exchange  therefor a certificate or  certificates  for fully paid and
nonassessable  shares,  which  certificates  shall be  delivered  by the  second
trading day after the date of delivery of the  Conversion  Notice,  and cash for
fractional  shares,  of Common Stock on the foregoing basis. The Series 2 Shares
shall be deemed to have been  converted,  and the person  converting the same to
have  become the holder of record of Common  Stock,  for all  purposes as of the
date of delivery of the Conversion Notice.

                  (f) The Company  shall,  so long as any of the Series 2 Shares
are  outstanding,  reserve and keep available out of its authorized and unissued
Common Stock, solely for the purpose of effecting the conversion of the Series 2
Shares,  such  number of shares  of Common  Stock as shall  from time to time be
sufficient  to  effect  the  conversion  of all  of the  Series  2  Shares  then
outstanding.

                  (g) The  Company  shall  pay any and all  taxes  which  may be
imposed  upon it with  respect to the issuance and delivery of Common Stock upon
the conversion of the Series 2 Shares as herein provided.  The Company shall not
be  required  in any event to pay any  transfer  or other taxes by reason of the
issuance  of such  Common  Stock in names other than those in which the Series 2
Shares surrendered for conversion are registered on the Company's  records,  and
no such  conversion  or issuance of Common  Stock shall be made unless and until
the person  requesting  such  issuance has paid to the Company the amount of any

                                       32
<PAGE>  

such tax, or has established to the satisfaction of the Company and its transfer
agent, if any, that such tax has been paid.

         (3)      VOTING RIGHTS. Holders of Series 2 Shares shall have no voting
rights, except as required by law.

         (4) REDEMPTION.  The Company may, at any time subsequent to ninety (90)
days after the issuance of the Series 2 Shares,  redeem the whole or any part of
the Series 2 Shares then outstanding at a redemption price of One Hundred Twenty
Dollars and Fifty Cents  ($120.50)  per Series 2 Share,  plus in each case a sum
equal to all accrued  and unpaid  dividends  thereon  through the date fixed for
redemption, in accordance with the following redemption procedures:

                  (a) In case of  redemption of only part of the Series 2 Shares
at any time  outstanding,  the Company  shall  designate  the amount of Series 2
Shares so to be  redeemed  and shall  redeem  such Series 2 Shares on a PRO RATA
basis. Subject to the limitations and provisions herein contained,  the Board of
Directors  shall  have the  power  and  authority  to  prescribe  the  terms and
conditions upon which the Series 2 Shares shall be redeemed from time to time.

                  (b) Notice of every redemption shall be given by mail to every
holder of record of any Series 2 Shares  then to be  redeemed,  at least  thirty
(30), but no more than ninety (90), days prior to the date fixed as the date for
the redemption thereof, at the respective  addresses of such holders as the same
shall appear on the stock transfer books of the Company.  The notice shall state
that the Series 2 Shares  shall be  redeemed  by the  Company at the  redemption
price  specified  above,  upon the surrender for  cancellation,  at the time and
place designated in such notice,  of the certificates  representing the Series 2
Shares to be redeemed,  properly endorsed in blank for transfer,  or accompanied
by proper  instruments  of  assignment  and transfer in blank,  with  signatures
guaranteed,  and bearing all necessary  transfer tax stamps thereto  affixed and
cancelled.  On and after the date specified in the notice described above,  each
holder of Series 2 Shares  called for  redemption  shall be  entitled to receive
therefor the specified  redemption price upon  presentation and surrender at the
place  designated in such notice of the  certificates for Series 2 Shares called
for redemption, properly endorsed in blank for transfer or accompanied by proper
instruments of assignment or transfer in blank, with signatures guaranteed,  and
bearing all necessary transfer tax stamps thereto affixed and cancelled.

                  (c)  If  the  Company  shall  give  notice  of  redemption  as
aforesaid (and unless the Company shall fail to pay the redemption  price of the
Series 2 Shares  presented for redemption in accordance  with such notice),  all
Series 2 Shares called for  redemption  shall be deemed to have been redeemed on

the date  specified in such  notice,  whether or not the  certificates  for such
Series 2 Shares shall be surrendered for redemption, and such Series 2 Shares so
called for  redemption  shall from and after  such date cease to  represent  any
interest  whatsoever  in the Company or its  property,  and the holders  thereof
shall  have no rights  other  than the right to receive  such  redemption  price
without any interest thereof from and after such date.

         (5) LIQUIDATION, DISSOLUTION, WINDING UP. In the event of any voluntary
or  involuntary  liquidation,  dissolution  or  winding up of the  Company,  the
holders of the Series 2 Shares  shall be  entitled to receive in cash out of the
assets of the  Company,  whether from capital or from  earnings,  available  for
distribution to its stockholders (the "Series 2 Funds"), before any amount shall
be paid to the holders of the Common Stock,  an amount equal to the Stated Value
per Series 2 Share plus any accrued and unpaid dividends,  provided that, if the
Series 2 Funds are  insufficient  to pay the full  amount due to the  holders of
Series 2 Shares and  holders of shares of other  classes or series of  preferred
stock of the  Company  that are of equal  rank  with the  Series 2 Shares  as to
payments of Series 2 Funds (the "Pari Passu Shares"), then each holder of Series
2 Shares and Pari Passu Shares shall  receive a percentage of the Series 2 Funds
equal  to the  full  amount  of  Series  2 Funds  payable  to such  holder  as a
percentage of the full amount of Series 2 Funds payable to all holders of Series
2 Shares and Pari Passu  Shares.  The purchase or  redemption  by the Company of
stock of any class, in any manner  permitted by law, shall not, for the purposes
hereof, be regarded as a liquidation,  dissolution or winding up of the Company.
Neither  the  consolidation  nor  merger of the  Company  with or into any other
corporation  or  corporations,  nor the sale or  transfer by the Company of less
than substantially all of its assets,  shall, for the purposes hereof, be deemed
to be a  liquidation,  dissolution  or winding up of the  Company.  No holder of
Series 2 Shares shall be entitled to receive any amounts  with  respect  thereto
upon any  liquidation,  dissolution  or winding up of the Company other than the
amounts provided for herein.

         (6) SERIES 2 RANK.  All shares of Common  Stock shall be of junior rank
to  all  Series  2  Shares  in  respect  to  the  preferences  as to  dividends,
distributions  and payments upon the  liquidation,  dissolution or winding up of
the  Company.  The rights of the shares of Common  Stock shall be subject to the
preferences  and  relative  rights of the  Series 2 Shares.  The Series 2 Shares
shall rank junior to the Company's  Convertible  Exchangeable  Preferred  Stock,
Series 1 in  respect  of  dividends  and  distributions  and  payments  upon the
liquidation, dissolution or winding up of the Company. The Company may authorize
and issue  additional or other  preferred  stock which is of equal rank with the
Series 2 Shares in respect of the preferences as to dividends and  distributions
and payments upon the liquidation,  dissolution or winding up of the Company. In
the event of the merger or  consolidation  of the Company  with or into  another

                                       34
<PAGE> 

corporation,   the  Series  2  Shares  shall  maintain  their  relative  powers,
designations and preferences provided for herein.

         (7) VOTE TO CHANGE THE TERMS OF SERIES 2 SHARES.  The affirmative  vote
at a meeting  duly  called for such  purpose of the  written  consent  without a
meeting  of the  holders  of the not  less  than  two-thirds  (2/3)  of the then
outstanding Series 2 Shares shall be required to amend,  alter, change or repeal
any of the powers, designations, preferences and rights of the Series 2 Shares.

         (8) AMENDMENTS  UPON  CONVERSION OR REDEMPTION OF OUTSTANDING  SERIES 2
SHARES.  When,  as a result of the  conversion  or  redemption  of the  Series 2
Shares,  no Series 2 Shares remain  outstanding,  the Board of Directors may, at
its discretion and without a vote of the  shareholders of the Company,  withdraw
this  Designation  in its entirety by providing for the filing of the applicable
amendment or restatement of the Company's  Restated  Articles of  Incorporation,
and the Series 2 Shares  designated hereby shall thereby return to the status of
authorized  but  unissued  and  undesignated  shares of  Preferred  Stock of the
Company.

                       ------------------------------

                    DESIGNATION OF RIGHTS AND PREFERENCES
              OF SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                       ------------------------------

         SECTION 1.   DESIGNATION OF SERIES A JUNIOR PARTICIPATING PREFERRED 
                      STOCK AND AMOUNT.

         The  shares of such  series  shall be  designated  as  "Series A Junior
Participating  Preferred Stock" (the "Series A Preferred  Stock") and the number
of shares constituting the Series A Preferred Stock shall be 600,000,  par value
$.02 per  share.  Such  number  of  shares  may be  increased  or  decreased  by
resolution of the Board of Directors;  PROVIDED, HOWEVER, that no decrease shall
reduce the number of shares of Series A  Preferred  Stock to a number  less than
the number of shares then  outstanding  plus the number of shares  reserved  for
issuance  upon the  exercise of Rights  (the  "Rights")  issued  pursuant to the
Rights  Agreement  dated as of April 10, 1996 between the  Corporation and First
Interstate Bank of Washington,  N.A., as Rights Agent (the "Rights  Agreement"),
and provided,  further,  that if more than a total of 600,000 shares of Series A
Preferred Stock shall be issuable upon the exercise of the Rights,  the Board of
Directors, pursuant to Section 23B.06.020 of the Washington Business Corporation
Act, shall direct by resolution that Articles of Amendment be properly  executed
and filed, in accordance with the provisions thereof,  providing for an increase
in the  authorized  shares of Series A Preferred  Stock to the largest number of
whole shares issuable upon exercise of the Rights.

         SECTION 2.        DIVIDENDS AND DISTRIBUTIONS.

                  (A)  Subject to the rights of the holders of any shares of any
series of Preferred  Stock (or any similar  stock) ranking prior and superior to
the Series A Preferred Stock with respect to dividends, the holders of shares of
Series A Preferred  Stock,  in preference  to the holders of Common  Stock,  par
value $.02 per share (the "Common Stock"), of the Corporation,  and of any other
junior  stock,  shall be entitled to  receive,  when,  as and if declared by the
Board of Directors  out of funds legally  available  for the purpose,  quarterly
dividends  payable  in cash on the  first  day of  March,  June,  September  and
December in each year (each such date being  referred to herein as a  "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (i) $1 and (ii)  subject to the  provision  for  adjustment  hereinafter  set
forth,  100 times the aggregate per share amount of all cash dividends,  and 100

                                       36
<PAGE> 

times the aggregate per share amount (payable in kind) of all noncash  dividends
or other distributions,  other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by  reclassification
or  otherwise),  declared on the Common  Stock since the  immediately  preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment  Date,  since the first  issuance of any share or fraction of a share of
Series A Preferred Stock. In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock  payable in shares of Common  Stock,  or
effect a subdivision or combination or consolidation  of the outstanding  shares
of Common Stock (by  reclassification or otherwise than by payment of a dividend
in shares of Common  Stock) into a greater or lesser  number of shares of Common
Stock,  then in each such case the amount to which holders of shares of Series A
Preferred Stock were entitled  immediately prior to such event under clause (ii)
of the  preceding  sentence  shall be adjusted by  multiplying  such amount by a
fraction  the  numerator  of which is the  number  of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                  (B) The  Corporation  shall declare a dividend or distribution
on the Series A Preferred  Stock as provided in paragraph  (A) of this Section 2
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend  payable in shares of Common Stock);  PROVIDED,  however,
that, in the event no dividend or  distribution  shall have been declared on the
Common Stock during the period between any Quarterly  Dividend  Payment Date and
the next subsequent  Quarterly Dividend Payment Date, a dividend of $1 per share
on the Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

                  (C)  Dividends  shall  begin to accrue  and be  cumulative  on
outstanding  shares of Series A  Preferred  Stock  from the  Quarterly  Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such  shares  is  prior to the  record  date  for the  first  Quarterly
Dividend  Payment  Date,  in which case  dividends on such shares shall begin to
accrue from the date of issue of such  shares,  or unless the date of issue is a
Quarterly  Dividend  Payment  Date or is a date  after the  record  date for the
determination  of  holders of shares of Series A  Preferred  Stock  entitled  to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such  dividends  shall begin to accrue and be  cumulative
from such Quarterly  Dividend  Payment Date.  Accrued but unpaid dividends shall
not bear interest.  Dividends paid on the shares of Series A Preferred  Stock in
an amount less than the total  amount of such  dividends at the time accrued and
payable on such shares shall be  allocated  pro rata on a  share-by-share  basis

                                       37
<PAGE> 

among all such shares at the time outstanding.  The Board of Directors may fix a
record  date for the  determination  of holders of shares of Series A  Preferred
Stock  entitled  to  receive  payment  of a dividend  or  distribution  declared
thereon,  which  record  date  shall be not more than 60 days  prior to the date
fixed for the payment thereof.

         SECTION 3.        VOTING RIGHTS.

         The  holders  of shares  of Series A  Preferred  Stock  shall  have the
following voting rights:

                  (A) Subject to the provision for  adjustment  hereinafter  set
forth,  each share of Series A Preferred  Stock shall entitle the holder thereof
to 100  votes on all  matters  submitted  to a vote of the  shareholders  of the
Corporation.  In the event the Corporation  shall at any time declare or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the  number of votes per share to which  holders  of shares of
Series A Preferred Stock were entitled  immediately prior to such event shall be
adjusted by multiplying  such number by a fraction the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

                  (B)  Except  as  otherwise   provided  herein,  in  any  other
Certificate of Designations  creating a series of Preferred Stock or any similar
stock,  or by law,  the  holders of shares of Series A  Preferred  Stock and the
holders of shares of Common Stock and any other capital stock of the Corporation
having  general  voting  rights shall vote  together as one class on all matters
submitted to a vote of shareholders of the Corporation.

                  (C) Except as set forth  herein,  or as otherwise  provided by
law, holders of Series A Preferred Stock shall have no special voting rights and
their consent  shall not be required  (except to the extent they are entitled to
vote with holders of Common Stock as set forth  herein) for taking any corporate
action.

         SECTION 4.        CERTAIN RESTRICTIONS.

                  (A)  Whenever  quarterly   dividends  or  other  dividends  or
distributions  payable on the Series A Preferred  Stock as provided in Section 2
are in  arrears,  thereafter  and until all  accrued  and unpaid  dividends  and

                                       38
<PAGE> 

distributions,  whether or not declared,  on shares of Series A Preferred  Stock
outstanding shall have been paid in full, the Corporation shall not:

                           (i)declare  or  pay  dividends,  or  make  any  other
                           distributions,  on any shares of stock ranking junior
                           (either  as  to   dividends   or  upon   liquidation,
                           dissolution  or winding up) to the Series A Preferred
                           Stock;

                           (ii)declare  or pay  dividends,  or  make  any  other
                           distributions,  on any  shares of stock  ranking on a
                           parity  (either as to dividends or upon  liquidation,
                           dissolution   or  winding   up)  with  the  Series  A
                           Preferred Stock, except dividends paid ratably on the
                           Series A Preferred Stock and all such parity stock on
                           which   dividends   are  payable  or  in  arrears  in
                           proportion  to the total amounts to which the holders
                           of all such shares are then entitled;

                           (iii)  redeem or  purchase or  otherwise  acquire for
                           consideration  shares  of any  stock  ranking  junior
                           (either  as  to   dividends   or  upon   liquidation,
                           dissolution  or winding up) to the Series A Preferred
                           Stock,  provided that the Corporation may at any time
                           redeem,  purchase or otherwise  acquire shares of any
                           such junior stock in exchange for shares of any stock
                           of  the  Corporation  ranking  junior  (either  as to
                           dividends or upon dissolution, liquidation or winding
                           up) to the Series A Preferred Stock; or

                           (iv)redeem  or  purchase  or  otherwise  acquire  for
                           consideration any shares of Series A Preferred Stock,
                           or any shares of stock  ranking on a parity  with the
                           Series A Preferred Stock, except in accordance with a
                           purchase offer made in writing or by publication  (as
                           determined  by the Board of Directors) to all holders
                           of such  shares  upon  such  terms  as the  Board  of
                           Directors,  after  consideration  of  the  respective
                           annual  dividend rates and other relative  rights and
                           preferences  of the  respective  series and  classes,
                           shall determine in good faith will result in fair and
                           equitable  treatment  among the respective  series or
                           classes.

                  (B) The  Corporation  shall not permit any  subsidiary  of the
Corporation  to purchase or otherwise  acquire for  consideration  any shares of
stock of the Corporation  unless the Corporation  could,  under paragraph (A) of
this Section 4,  purchase or  otherwise  acquire such shares at such time and in
such manner.
 
                                       39
<PAGE> 



         SECTION 5.        REACQUIRED SHARES.

         Any shares of Series A Preferred Stock purchased or otherwise  acquired
by the  Corporation  in any manner  whatsoever  shall be retired  and  cancelled
promptly  after the  acquisition  thereof.  All such  shares  shall  upon  their
cancellation become authorized but unissued shares of Preferred Stock and may be
reissued as part of a new series of Preferred  Stock  subject to the  conditions
and   restrictions  on  issuance  set  forth  herein,   in  the  Certificate  of
Incorporation of the Corporation (the "Certificate of Incorporation"), or in any
other  Certificate of  Designations  creating a series of Preferred Stock or any
similar stock or as otherwise required by law.

         SECTION 6.        LIQUIDATION, DISSOLUTION OR WINDING UP.

         Upon any liquidation,  dissolution or winding up of the Corporation, no
distribution  shall be made (a) to the holders of shares of stock ranking junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series A Preferred Stock unless,  prior thereto, the holders of shares of Series
A Preferred  Stock shall have received  $100 per share,  plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such  payment,  provided  that the  holders of shares of Series A
Preferred  Stock  shall be entitled  to receive an  aggregate  amount per share,
subject to the  provision for  adjustment  hereinafter  set forth,  equal to 100
times the aggregate  amount to be distributed  per share to holders of shares of
Common  Stock,  or (b) to the  holders  of shares of stock  ranking  on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred  Stock,  except  distributions  made  ratably on the Series A
Preferred  Stock and all such parity stock in proportion to the total amounts to
which the  holders  of all such  shares  are  entitled  upon  such  liquidation,
dissolution  or  winding  up.  In the event  the  Corporation  shall at any time
declare  or pay any  dividend  on the Common  Stock  payable in shares of Common
Stock,  or  effect  a  subdivision  or  combination  or   consolidation  of  the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock,  then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (a) of the  preceding  sentence  shall be
adjusted by multiplying  such amount by a fraction the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

                                       40

<PAGE> 



         SECTION 7.        CONSOLIDATION, MERGER, ETC.

         In case the  Corporation  shall enter into any  consolidation,  merger,
combination  or other  transaction  in which  the  shares  of  Common  Stock are
exchanged for or changed into other stock or  securities,  cash and/or any other
property,  then in any such case each share of Series A Preferred Stock shall at
the same time be  similarly  exchanged  or  changed  into an amount  per  share,
subject to the  provision for  adjustment  hereinafter  set forth,  equal to 100
times the aggregate amount of stock, securities,  cash and/or any other property
(payable  in kind),  as the case may be,  into  which or for which each share of
Common Stock is changed or exchanged.  In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock,  or  effect  a  subdivision  or  combination  or   consolidation  of  the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common  Stock,  then in each such case the  amount set forth in the
preceding  sentence with respect to the exchange or change of shares of Series A
Preferred  Stock shall be adjusted by multiplying  such amount by a fraction the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

         SECTION 8.        NO REDEMPTION.

         The shares of Series A Preferred Stock shall not be redeemable.

         SECTION 9.        RANK.

         The Series A Preferred Stock shall rank, with respect to the payment of
dividends  and the  distribution  of  assets,  junior to all series of any other
class of the Preferred Stock.

         SECTION 10.  AMENDMENT.

         The  Certificate  of  Incorporation  shall not be amended in any manner
that would materially alter or change the powers,  preferences or special rights
of the Series A  Preferred  Stock so as to affect  them  adversely  without  the
affirmative vote of the holders of at least two-thirds of the outstanding shares
of Series A Preferred Stock, voting together as a single class.
