 FORM 10-K

 PRELIMINARY STATEMENT

    Since May 15, 2000, International Isotopes Inc, (together with its
wholly owned Idaho subsidiary, International Isotopes Idaho Inc., hereafter     
referred to as the "Company" or "I(3)") has stated that our cash, cash          
equivalents and cash that may be generated from operations may be insufficient  
to meet our anticipated cash needs. In late 2000, after it was apparent that we 
could not raise the additional equity financing we needed, we indicated that the
Company would pursue strategic alternatives to sell certain assets in order to  
continue operations.                                                            

    On January 16, 2001, the Company completed the sale of the Woodrow
Spencer office and warehouse facility located in Denton, Texas for proceeds of  
$950,000, less closing costs of $63,811. The facility had a net book value of   
$1,095,962 December 31, 2000. Based on the anticipated sales proceeds, the      
Company recorded an impairment charge related to this facility in the amount of 
$209,773. The Company used the proceeds to reduce its revolving line of credit  
by $863,890 (including accrued interest of $23,400) and fund operating expenses 
with the remaining amounts. On April 20, 2001, the Company completed the sale of
the Radiopharmaceutical Manufacturing Facility to NeoRx Corporation ("NeoRx")   
for cash proceeds of $12.0 million and warrants to purchase 800,000 shares of   
NeoRx common stock. The assets acquired by NeoRx had a net book value of        
approximately $11,304,724 at December 31, 2000. The Company used the proceeds to
repay net advances made by NeoRx in the amount of $861,060, reduce its note     
payable to a commercial lender by $1,296,469 (including interest of $36,578),   
reduce its revolving line of credit by $2,614,023 (including accrued interest of
$45,857), reduce its capital lease obligations by $3,291,289, repay a portion of
the $1,145,000 note payable to William Nicholson, the former Chairman of the    
Board for $348,000 and fund other operating expenses. On April 27, 2001, the    
Company completed the sale of its brachytherapy seed assets ("Seed Assets") to  
Imagyn Medical Technologies, Inc. ("Imagyn") for cash proceeds of approximately 
$5.0 million. The Seed Assets had a net book value of $5,416,294 at December 31,
2000. Based on the anticipated sales proceeds, the Company recorded an          
impairment charge of $416,294 related to these assets. The Company used the     
proceeds to repay advances and expenses incurred by Imagyn in the amount of     
$108,786 and reduce its note payable to a commercial lender by $4,645,582       
(including accrued interest of $25,768), reduce capital lease obligations by    
$145,632 and fund other operating expense in the amount of $100,000.            

        In order to further reduce the Company's debt obligations, the Company
plans to sell the Shady Oaks/LINAC ("Linear Accelerator") facility, property in 
Waxahachie, Texas, and excess LINAC components. The Company has signed a        
definitive asset sales agreement dated June 6, 2001 to sell the Shady Oaks/LINAC
radioisotope production facility for net proceeds of approximately $7.7 million.
This sale is expected to close during the fourth quarter of 2001. The net book  
value of the Shady Oaks/LINAC assets was $23,053,925 at December 31, 2000. Based
on the anticipated sales prices, the Company recorded an impairment charge as of
December 31, 2000 in the amount of $15,889,765 to write down the assets to      
estimated fair value less costs to sell. The property in Waxahachie, Texas has a
net book value of $409,531. Based on an external appraisal conducted, the       
Company believes that proceeds from the sell of this property will be in excess 
of its net book value. Based on discussions with potential buyers, the Company  
expects to sell the excess LINAC components for more than $800,000. (The sale of
the Woodrow Spencer facility, Radiopharmaceutical Manufacturing Facility, the   
Seed Business, the Shady Oaks/LINAC, the Waxahachie property and the excess     
LINAC components are referred to as the "Asset Sales").                         

         In April 2001, the Company also successfully completed a composition of
creditors pursuant to which we were able to reduce our trade debt by $825,330,  
as 90% of our unsecured creditors agreed to accept a payment equal to 50% of the
amount owed to them. In addition, we have reduced our secured bank debt         
substantially and anticipate the possibility of reducing it further upon the    
closing of the Shady Oaks/LINAC asset sale.

        The company emerging subsequent to the Asset Sales will consist solely
of our I(4) Idaho operations and the size and nature of the business will be    
substantially less in scope. In addition, the Company is not expected to        
generate sufficient cash flow to meet our operational needs during the remainder
of 2001. As such, the continuance of our business for the foreseeable future is 
dependent on our ability to secure additional financing or generate cash from   
operations with respect to the Idaho operations.                                

        Any person considering an investment in any of our securities is urged
to consider both the risk that the Company could cease operations and the risk  
that our securities will be worthless subsequent to completion of the Asset     
Sales. All of the statements set forth in this report are qualified by reference
to those facts. Please see "Item 7, Management's Discussion and Analysis of     
Financial Condition and Results of Operations" for a discussion of these and    
other risk factors relating to us and an investment in our securities.

PART I                                                                          

Item 1.  BUSINESS                                                               

GENERAL                                                                         

    International Isotopes Inc, a Texas corporation (together with its
wholly owned subsidiary, International Isotopes Idaho Inc. ("I(4)") hereafter   
referred to as "we" or the "Company" or "I(3)") was initially formed to produce,
market and distribute a broad range of products used in diagnostic and          
therapeutic nuclear medicine, research and industry. The Company's strategy was 
to establish a position in the market as the first U.S. based independent       
commercial manufacturer of a broad range of radioisotopes, pharmaceutical grade 
radioisotopes and finished radiopharmaceuticals, including medical devices (on a
contract or joint venture basis) for the nuclear medicine industry.             

  In furtherance of that strategy, I(3) acquired the proton linear
accelerator ("LINAC") and related assets, redesigned and reconfigured the LINAC 
for production of radioisotopes, acquired land and designed and constructed     
facilities for the production and distribution of radioisotopes,                
radiopharmaceuticals and brachytherapy products.                                

    The Company's 35,000 square foot building housing the Radioisotope
Production Facility was completed in September 1998. We had also completed a    
27,000 square foot building housing the Administration, Manufacturing and       
Service Facility for corporate offices and construction of production equipment.
In addition, we constructed a 25,000 square foot finished radiopharmaceutical   
production suite in the Radiopharmaceutical Manufacturing Facility and also     
remodeled the separate 12,000 square foot building located at this site for     
installation of the Cyclotron used in the production of short-lived isotopes and
certain research isotopes.                                                      

During 1999, the Company concentrated its efforts on making a 
transition from a development stage enterprise to an operating manufacturing    
company with a focus on finished radiopharmaceuticals. The steps needed to make 
this transition proved to be more costly and complex than anticipated, causing  
the Company to miss many of our milestones. In addition, we were conducting     
testing and final modifications for operation of the Radioisotope Production    
Facility and the LINAC in conformity with the Company's redesign and            
reconfiguration. The challenges we encountered while bringing the LINAC into    
regular operations were also more complicated than originally estimated. As the 
year progressed we found it necessary to make strategic changes in our structure
and plans.                                                                      

RECENT DEVELOPMENTS                                                             

During late 2000, it became apparent that the Company was not going to be       
successful in completing a third round of preferred stock funding. Since the    
Company had been a development stage company with virtually no other sources of 
funds than additional financing, this funding was essential to continue         
operations. As a result, the Company investigated and pursued several           
alternatives in an attempt to salvage its business. First, we pursued several   
partnering relationships with customers. These attempts were not successful     
primarily due to the Company's weak financial condition. We also considered     
seeking relief or liquidation under Chapter 11 and Chapter 7 of the Bankruptcy  
Code, respectively. It was concluded that bankruptcy was not the best option for
the Company or creditors since it was likely that the claims of secured and     
unsecured creditors and bankruptcy administration costs would exceed the        
realizable value of our assets and that unsecured creditors and shareholders    
would receive nothing due to radiation license liabilities, the anticipated     
difficulty in selling assets containing radioactive materials, and the probable 
loss of critical highly skilled employees. Without these key employees the      
assets' value to a potential purchaser would be greatly diminished.             

    Therefore, the Company decided to pursue a strategy of divestiture
outside of bankruptcy to attempt to maximize value for our creditors and        
shareholders. From November 2000 until the present, the Company laid off 183    
personnel and closed two of its operating facilities. As of July 31, 2001, the  
Company had 16 employees

in Denton, Texas and in Idaho. Following the Asset Sales described in more      
detail below, the Company will have 13 employees located at our I(4) facility in
Idaho.                                                                          

        Since early December 2000, banking institutions and entities that have
acquired certain of the Company assets have funded continuing operations. The   
Company's primary lender increased our borrowing capacity in the amount of $2.4 
million and NeoRx Corporation ("NeoRx") advanced the Company $930,000, which was
converted to purchase price upon consummation of the sale of our                
Radiopharmaceutical Manufacturing Facility.                                     

    On January 16, 2001, the Company completed the sale of the Woodrow
Spencer office and warehouse facility located in Denton, Texas for proceeds of  
$950,000, less closing costs of $63,811. The facility had a net book value of   
$1,095,962 December 31, 2000. Based on the anticipated sales proceeds, the      
Company recorded an impairment charge related to this facility in the amount of 
$209,773. The Company used the proceeds to reduce its revolving line of credit  
by $863,890 (including accrued interest of $23,400) and fund operating expenses 
with the remaining amounts.                                                     

On April 20, 2001, the Company completed the sale of the      
Radiopharmaceutical Manufacturing Facility to NeoRx Corporation ("NeoRx") for   
$12.0 million in cash and warrants to purchase 800,000 shares of NeoRx common   
stock. The assets acquired by NeoRx had a net book value of $11,304,724 at      
December 31, 2000. The Company used the proceeds to repay net advances made by  
NeoRx in the amount of $861,060, reduce its note payable to a commercial lender 
by $1,296,469 (including interest of $36,578), reduce its revolving line of     
credit by $2,614,023 (including accrued interest of $45,857), reduce its capital
lease obligations by $3,291,289, repay a portion of the $1,145,000 note payable 
to William Nicholson, the former Chairman of the Board for $348,000 and fund    
other operating expenses.                                                       

        On April 27, 2001, the Company completed the sale of its brachytherapy
seed assets (the "Seed Business") to Imagyn Medical Technologies, Inc.          
("Imagyn") for cash proceeds of approximately $5.0 million. The assets acquired 
by Imagyn had a net book value of $5,416,294 at December 31, 2000. Based on the 
anticipated sales proceeds, the Company recorded an impairment charge of        
$416,294 related to these assets. The Company used the proceeds to repay        
advances and expenses incurred by Imagyn in the amount of $108,786 and reduce   
its note payable to a commercial lender by $4,645,582 (including accrued        
interest of $25,768), reduce capital lease obligations by $145,632 and fund     
other operating expense in the amount of $100,000.                              

 On June 6, 2001, the Company signed a definitive asset purchase
agreement with Antich Medical Imaging, Inc. ("AMII") to sell the Shady          
Oaks/LINAC facility for net proceeds of approximately $7.7 million. This sale is
expected to close during the fourth quarter of 2001. In anticipation of the     
sale, the Company recorded a $15.9 million charge to write down the related     
assets to estimated fair value less costs to sell.                              

ONGOING OPERATIONS                                                              

   Subsequent to completion of the transactions discussed above, the
Company will consist solely of the I(4) Idaho operations. As such, the          
operations will be substantially scaled back in size and scope. In addition, we 
do not expect to generate positive cash flow this year and will continue to be  
dependent on external financing for the foreseeable future.                     

  Earlier this year I(4) terminated its commercial use subcontract
agreement that was first established in 1996 at the Idaho National Engineering  
and Environmental Laboratory. This contract had permitted access to the Idaho   
research reactor for isotope production but also included the high cost of      
facility operations. This contract was terminated in an effort to curtail costs.
As a substitute, two new agreements have been put in place with the current site
contractor. These new agreements are for i) providing contract labor support    
services for operations of the Department of Energy ("DOE") owned hot cells     
facility and ii) access to the reactor facility for continued isotope           
production. The end result of these contract changes has been a reduction in the
cost of operations and continued reactor access for isotope sales in cobalt,    
nickel, and iridium. However, these contracts

expire September 30, 2001 and it is likely that the hot cell labor services will
not be continued after that time. Without continued hot cell access the         
commercial isotope production in the reactor would have to be suspended until   
I(4) can reestablish isotope processing capability in its Idaho Falls facility. 

INDUSTRY OVERVIEW AND TARGET MARKETS                                            

The industry and markets which require or involve the use of  
radioactive material are diverse. Our current I(4) operations involve several of
these diverse applications. First, our radioisotope production supplies bulk    
materials, which are used in a variety of industrial applications and medical   
devices. Second, we purchase from third parties machine produced radioisotopes  
in order to manufacture medical flood sources, which are used for operational   
checks on gamma camera systems. Finally, we support the packaging and           
measurement of gemstones that have undergone reactor irradiation for color      
enhancement.                                                                    

PRODUCTS                                                                        

      Reactor Produced Radioisotopes - we produce several radioisotopes in
bulk form for sale as raw ingredients for several products. Iridium-192 is      
supplied to various customers who manufacture sealed sources for industrial     
radiography. High activity Cobalt-60 is supplied in bulk for customers to       
manufacture external radiation therapy devices. Nickel-63 is supplied in bulk   
form to customers, which incorporate this radioisotope into a variety of devices
and detection equipment components.                                             

   Flood Source Contract Manufacture - I(4) is an exclusive contract
manufacturer of flood sources for RadQual Inc. The flood sources are used for   
the daily operational quality control checks of SPECT or Planar Imaging gamma   
cameras. These gamma cameras are a fundamental imaging modality used in         
thousands of nuclear medicine and cardiovascular imaging centers around the     
country.                                                                        

     Gemstone Processing - We also package gemstone for irradiation in a
reactor, and then process this material (by cleaning and measurement) following 
irradiation. The irradiation process is used for color enhancement of the       
gemstone. We provide this service on a subcontract basis only.                  

COMPETITION                                                                     

      Each of our various production and manufacturing areas is subject to
significant competition. Reactor produced radioisotopes are supplied by many    
reactor facilities around the world including two domestic sources (the         
University of Missouri Research Reactor and the High Flux Isotope Reactor       
located in Oak Ridge Tennessee). Most radioisotopes from reactors are produced  
in bulk form, are very competitively priced, and offer small margins for profit.
Medical flood sources are being produced by several other manufacturers in the  
U.S. and overseas, including Isotope Products Laboratory, North American        
Scientific Inc., and Nycomed Amersham. There are several producers of Gemstone  
who utilize the irradiation process for color enhancement and engage the        
services of other companies to provide pre and post irradiation processing.     

MANUFACTURING                                                                   

  Quality assurance and quality control are performed according to
current Good Manufacturing Practices ("GMP") regulations and NQA-1. The Company 
maintains quality control, and is responsible for the quality of all components,
containers, in-process materials, labeling and final products.                  

GOVERNMENT REGULATION                                                           

The Company has obtained a license from the Nuclear Regulatory
Commission, Region IV which permits use and possession of by-product material.  
The scope of this license includes radioactive gemstone processing,             
environmental sample monitoring, and various research and development           
activities.

  REGULATION OF RADIOISOTOPE PRODUCTION AND RADIOACTIVE WASTE. The
manufacture of radioisotopes and radiopharmaceuticals is subject to extensive   
federal regulation. Prior to commencing operations in our newly leased Idaho    
facility, I(4) obtained approval from the Nuclear Regulatory Commission. The new
production facility will not handle "special nuclear materials" (i.e. nuclear   
fuels and weapons grade uranium, thorium and plutonium) and, therefore, will not
be designated as a "fixed nuclear facility". We are not subject to regulation by
the Department of Energy, except for those remaining isotope production         
operations taking place at the Idaho National Engineering Laboratory.           

        Pursuant to the Low Level Radioactive Waste Policy Act of 1980, states
are required to assure the safe disposal of mildly radioactive materials. The   
disposal of radioactive waste is regulated in Idaho by the Nuclear Regulatory   
Commission, Region IV. Radioactive waste produced falls into the category of    
low-level radioactive waste as the production and processing of radioisotopes   
generate a certain amount of low-level, solid radioactive waste.                

         OTHER REGULATIONS. In the event we enter into agreements with suppliers
to acquire neutron-produced research and therapeutic radioisotopes we will be   
subject to additional regulations of the Nuclear Regulatory Commission.         

EMPLOYEES                                                                       

         As of July 31, 2001, the Company had 16 full-time employees, consisting
of 3 executive officers, 11 additional production, scientific and professional  
personnel and 2 administrative personnel. As a condition of the Asset Sales, the
Company identified 38 employees who perform functions in connection with the    
Radiopharmaceutical Manufacturing Facility and the Seed Business. In conjunction
with the Asset Sales, the purchasers, Imagyn and NeoRx, offered employment to   
these employees at their discretion. Following completion of the Asset Sales,   
the remaining Company employees will be located at the Idaho facilities and     
consist of 13 full time employees. The employees remaining following the Asset  
Sales will include 1 executive officer, 1 radiation safety officer, 2           
administrative personnel, and 9 professionals, supervisors and technicians.     

ITEM 2.  PROPERTIES                                                             

In November 1997, the Company purchased an 80,000 square foot 
office/manufacturing facility and a 12,000 square foot warehouse referred to as 
our "Radiopharmaceutical Manufacturing Facility". Total cost for this facility, 
located on 12 acres at 3100 Jim Christal Road, Denton, Texas, including         
improvements for offices, furnishings, HVAC, and a suite of production clean    
rooms and equipment, was approximately $9,300,000. The 12,000 square foot       
warehouse houses the 42 MeV Cyclotron, donated by MD Anderson Cancer Center to  
the University of North Texas ("UNT"), which was remodeled and operated by the  
Company under a lease with UNT to produce short-lived and research              
radioisotopes. On April 20, 2001 the Company completed the sale of the          
Radiopharmaceutical Manufacturing Facility including the Cyclotron lease to     
NeoRx.                                                                          

      In early 1998, the Company completed construction of a 27,000 square
foot facility, for administration, manufacturing and services located on 1.6    
acres in Denton, Texas at a cost of $ 1,260,000. This facility was sold for     
gross proceeds of $950,000 in January, 2001. Also in 1998, the Company completed
construction of the building housing its 35,000 square foot Radioisotope        
Production Facility devoted to the LINAC at an approximate cost of $7,524,000.  
This building is located on 20 acres of land in an Industrial Research Park in  
Denton, Texas acquired by the Company in 1996. In June 2001 the Company entered 
into an agreement to sell this facility including the LINAC to AMII for net     
proceeds of approximately $7.7 million. This transaction is expected to close in
the fall of 2001.                                                               

       In March 1998, the Company purchased 115 acres of land in Waxahachie,
Texas from the State of Texas at a cost of $424,000. This site includes a       
building with 25,059 square feet that can be used as a secondary accelerator    
production and testing site. The Company is actively seeking to sell this       
property. There can be no assurance that the proceeds from the sale will be     
sufficient to recover the recorded amounts. Accordingly, the Company may realize
a loss on the sale if such sale is consummated.

     I(4) also holds a 5-year lease with purchase options on a new 6,500
square foot facility located in Idaho Falls. This facility is currently licensed
under the Nuclear Regulatory Commission and is being used for processing of     
irradiated gemstone and contract manufacturing of flood sources for RadQual     
LLC.                                                                            

ITEM 3. LEGAL PROCEEDINGS                                                       

         On January 4, 2000, a petition was filed in the 393rd Judicial District
Court, Denton County, Texas, Cause No. 2000-60001-393, Carl Seidel vs.          
International Isotopes, Inc. Carl Seidel ("Seidel"), the former CEO and         
President of the Company, alleging a breach of contract with regard to the      
payment of severance in connection with his departure from the Company and with 
regard to reimbursement for tax liability incurred by Seidel in connection with 
the exercise of Seidel's incentive stock options. Seidel sought $270,375.00 in  
severance and $373,523.00 as reimbursement for tax liability. On April 10, 2001,
the Company settled the case with Mr. Seidel for $35,000.                       

   During 2000-2001 the Company was a defendant in several law suits
involving creditor and supplier claims. The Company has settled each of these   
claims.                                                                         

        The Company is a party to legal proceedings incidental to its business
which, in the opinion of management, are not expected to have a material adverse
effect on the Company's consolidated financial position, operating results or   
liquidity.                                                                      

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS                     

    No matters were submitted to a vote of security holders during the
fourth quarter of the fiscal year covered by this Annual Report on Form 10-K.   

PART II

STOCKHOLDER MATTERS                                             

 Prior to the completion of our IPO in August 1997, there was no
established public trading market for our Common Stock. At that time the        
Company's Common Stock commenced trading on the NASDAQ SmallCap Market under the
symbol of "INIS". The Company was also listed on the Boston Stock Exchange under
the symbol "ITL". High and low sales prices reported by Nasdaq during the       
periods indicated are shown below:

        On January 3, 2001 we were formally notified that the Company's common
stock had failed to maintain a minimum bid price of $1.00 over the previous 30  
consecutive trading days as required by the Nasdaq SmallCap Market under        
Marketplace Rule 4310(c)(4) (the "Rule"). Therefore, in accordance with         
Marketplace Rule 4310(c)(8)(B), we were provided 90 calendar days to regain     
compliance with this Rule. On April 3, 2001, we were notified that our          
securities had been delisted.

       On July 31, 2001, there were over 260 holders of record of the Common
Stock (although we believe that the number of beneficial owners of Common Stock 
is approximately 3,500). The closing price on July 31, 2001 of a share of common
stock was $0.05. We have never paid any cash dividends on the common stock, and 
the Board of Directors does not anticipate paying cash dividends on common stock
in the near future. We intend to retain any future earnings, if any, to provide 
funds for the operation and expansion of our business.                          

RECENT SALES OF UNREGISTERED SECURITIES                                         

        On June 15, 2000, we completed a private placement of 10,000 shares of
7% cumulative redeemable convertible $0.01 par value $1,000 face value preferred
stock ("Series B Preferred Stock") together with 2,500,000 warrants to purchase 
common stock at $4.00 per share, for aggregate proceeds of $10 million, before  
issuance costs of $595,000. This issuance was exempt from federal securities    
registration pursuant to Section 4(2) of the Securities Act of 1933 and Rule 506
of Regulation D adopted thereunder. Dividends are 7% per annum payable in cash  
or common stock (at the Company's option) beginning September 1, 2000 and       
continuing quarterly thereafter through June 1, 2003. If paid in common stock,  
the number of shares is based on the average market price for the 10 trading    
days immediately preceding the dividend payment date (the "Average Price").     

        The Series B Preferred Stock is mandatorily redeemable on May 31, 2003
in cash or common stock at the then Average Price, at the Company's option. When
originally issued, holders of Series B Preferred Stock could require early      
redemption on December 1, 2000 and June 1, 2001. Mandatory redemption events    
included change in control, suspension or delisting from NASDAQ, the BSE or any 
subsequent market on which the common stock is listed for five consecutive days,
breach by the Company of any representations, warranties or other conditions in 
the preferred stock purchase agreement, and other events. In March, 2001, the   
holders of Series B Preferred Stock agreed to a modification in terms, which    
removed their early redemption rights and certain adjustments to their          
conversion price. The Series B Preferred Stock is now convertible to common     
stock at a fixed price of $2.00 per share and the warrants are exercisable at   
any time up to June 1, 2003 at $4.00 per share, subject to adjustment in the    
case of stock splits or stock dividends. As consideration for these concessions,
we distributed to the holders of Series B Preferred Stock an aggregate of       
360,850 Warrants to purchase NeoRx common stock that the Company had received in
connection with the sale of the Radiopharmaceutical Manufacturing Facility to   
NeoRx.                                                                          

       Also in March, 2001 the Company and the holders of Series A Preferred
Stock modified the terms of the Series A Preferred Stock to reset the conversion
price at $2.00, subject to modification only in certain cases, such as stock    
splits or dividends. In consideration for their agreement to modify the terms of
their preferred stock, the Series A holders were distributed an aggregate of    
439,150 Warrants to purchase NeoRx common stock, which the Company had received 
from NeoRx in connection with the sale of the Radiopharmaceutical Manufacturing 
Facility.                                                                       

      On October 4, 2000, we issued 100,000 shares to Stonegate Securities
for services provided in connection with a private placement of common stock and
warrants that closed in February 2000. The stock was issued at $3.88 per share  
for a total consideration of $387,500. This issuance was exempt from federal    
securities registration pursuant to Section 4(2) of the Securities Act of 1933  
and Rule 506 of Regulation D adopted thereunder.                                

     On October 20, 2000, holders of 1,783 shares of Series B redeemable
convertible preferred stock, with a face value of $1,783,000, converted their   
preferred stock to 445,750 shares of common stock at the conversion price of    
$4.00 per share. In addition, on October 20, 2000, the Company elected to pay   
prorated dividends on the converted shares of $17,097, by issuing 6,104 shares  
of common stock at $2.80 per share.                                             

        On October 26, 2000, we issued 25,000 shares of common stock valued at
$43,750, to an employee as compensation for services provided. This issuance was
exempt from federal securities registration pursuant to Section 4(2) of the     
Securities Act of 1933 and Rule 506 of Regulation D adopted thereunder.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND         
RESULTS OF OPERATIONS                                           

OVERVIEW                                                                        

         This overview contains forward-looking statements that include, but are
not limited to, the Company's expectations regarding its future financial       
condition and operating results, product development, business and growth       
strategy, market conditions and competitive environment. The Company's actual   
results could differ materially from those anticipated in these forward-looking 
statements as a result of certain factors disclosed in this document.           

         Since its incorporation in November 1995, the Company's operations have
been concentrated in acquiring its proton linear accelerator ("LINAC") and      
related assets, redesigning and reconfiguring the LINAC for production of       
radioisotopes, developing production methods, acquiring land, designing and     
constructing facilities for the production and distribution of radioisotopes,   
radiopharmaceuticals and brachytherapy products, raising capital, selling       
certain accelerator components and excess equipment and entering into strategic 
alliances with medical and pharmaceutical companies, universities and other     
institutions.                                                                   

 During 1999, we concentrated our efforts on making a successful
transition from a development stage enterprise to an operating manufacturing    
company with a focus on finished radiopharmaceuticals. The steps needed to make 
this transition proved to be more costly and complex than we had anticipated,   
causing us to miss many of our milestones.                                      

         During 2000, it became apparent that we were not going to be successful
in completing a third round of preferred stock funding. Since we had been a     
development stage company with virtually no other sources of funds than         
additional financing, this funding was essential to continue operations. As a   
result, we investigated and pursued several alternatives in an attempt to       
salvage the business. First, we pursued several partnering relationships with   
customers. These attempts were not successful primarily due to our weak         
financial condition. We also considered seeking relief or liquidation under     
Chapter 11 and Chapter 7 of the Bankruptcy Code, respectively. We concluded that
bankruptcy was not the best option for the Company or our creditors as the      
claims of secured creditors and unsecured creditors and bankruptcy              
administration costs would exceed the realizable value of our assets and        
unsecured creditors and shareholders would receive nothing due to the radiation 
license liabilities, the anticipated difficulty in selling assets containing    
radioactive materials, and the probable loss of critical highly skilled         
employees. Without these key employees the assets' value to a potential         
purchaser would be greatly diminished.                                          

      Therefore, we decided to pursue a strategy of divestiture outside of
bankruptcy to attempt to maximize value for our creditors and shareholders.     
Since early December 2000, banking institutions and entities that have acquired 
certain Company assets have funded our continuing operations. Our primary lender
increased our borrowing capacity in the amount of $2.4 million and NeoRx        
advanced the Company $930,000, which was converted to purchase price upon       
consummation of the sale of our Radiopharmaceutical Manufacturing Facility.     

        On March 20, 2001, we signed an asset purchase agreement with NeoRx to
sell our Radiopharmaceutical Manufacturing Facility for $12.0 million in cash   
and warrants to purchase 800,000 shares of NeoRx common stock. The purchase     
price was reduced by the $930,000 previously advanced by NeoRx. The transaction 
closed on April 20, 2001. The net book value of the tangible equipment was      
approximately $11.3 million at December 31, 2000. The net proceeds from the sale
were used to repay the aforementioned advance from NeoRx and, along with the $6 
million note payable assumed by NeoRx, reduced long-term debt approximately $3.9
million and reduced capital lease obligations by $3.3 million. The remaining    
funds were used to pay closing costs totaling $383,000 and to satisfy various   
creditor obligations.                                                           

                  On March 20, 2001, we signed a letter of intent with Imagyn to
sell the brachytherapy seed assets for cash proceeds of approximately $5.0      
million. The transaction closed on April 27, 2001. The net book value of the    
tangible equipment related to this transaction was $5.4 million at December 31, 
2000. Based on the anticipated sales proceeds, the Company recorded an          
impairment charge of $416,294 related to these assets at

December 31, 2000. The proceeds were used to repay advances and expenses        
incurred by Imagyn in the amount of $108,786 and reduce the note payable to a   
commercial lender by $4,645,582 (including accrued interest of $25,768), reduce 
capital lease obligations by $145,632 and fund other operating expense in the   
amount of $100,000.                                                             

         In April 2001, the Company also successfully completed a composition of
creditors pursuant to which we were able to reduce our trade debt by $825,330,  
as 90% of our unsecured creditors agreed to accept a payment equal to 50% of the
amount owed to them. In addition, we have reduced our secured bank debt         
substantially and anticipate the possibility of reducing it further upon the    
closing of the Shady Oaks/LINAC asset sale.                                     

     Subsequent to the close of the asset sales to NeoRx Corporation and
Imagyn Medical, Inc., in April and May of 2001, International Isotopes and Texas
State Bank cooperated to restructure several of the notes and loans established 
for the company. A balance limit on the company's main commercial loan was      
reduced from $15,000,000 to $7,750,000 with an interest rate of 9.6% per annum  
and all principal and interest payments were suspended until the loan reaches   
maturity on January 27, 2002. The company's previous $5 million line of credit  
note was reduced to a $1 million line, also with an interest rate 9.6% per      
annum. Principal and interest payments on the line of credit have also been     
deferred until the maturity date of April 27, 2002. Immediately after closing   
approximately $400,000 was drawn against this line of credit to reduce the      
commercial loan to the limited amount of $7,750,000 and address miscellaneous   
legal expenses and payments made by Texas State Bank on the company's behalf.   
The balance of this line of credit is to be used to support the continuing cash 
needs of the company. Texas State Bank also opened a new $500,000 commercial    
line of credit with an interest rate of 9.6% per annum to support the interim   
operations of the Shady Oaks/LINAC facility pending the completion of the sale  
of that property and equipment. Principal and interest payments on this line of 
credit were also deferred until January 27, 2002. Funds from the closing were   
also used to pay $348,000 of the $1,145,000 note payable to William Nicholson,  
the former Chairman of the Board. The balance due Mr. Nicholson is $797,000 plus
accrued interest.                                                               

 On June 6, 2001, the Company signed a definitive asset purchase
agreement with AMII to sell the Shady Oaks/LINAC facility for net proceeds of   
$7.7 million. This sale is expected to close during the fourth quarter of 2001. 
In anticipation of the sale, we recorded a $15.9 million charge to write down   
the related assets to estimated fair value less costs to sell.                  

         Long-lived assets and certain identifiable intangibles are periodically
reviewed for impairment whenever events or changes in circumstances indicate    
that the carrying amount of an asset may not be recoverable. Recoverability of  
assets to be held and used is measured by a comparison of the carrying amount of
an asset to future net cash flows expected to be generated by the asset. If such
assets are considered to be impaired, the impairment to be recognized is        
measured by the amount by which the carrying amount of the assets exceeds the   
fair value of the assets. Assets to be disposed of are reported at the lower of 
the carrying amount or fair value less costs to sell. The Company periodically  
reviews long-lived assets whenever events or changes in circumstances indicate  
that the carrying amount of such assets may not be recoverable. When such       
circumstances occur, the Company evaluates the possible effects on the carrying 
amount of such assets. The Company's estimates of future gross revenues and     
operating cash flows, the remaining estimated lives of long-lived assets, or    
both could be reduced in the future due to changes in, among other things,      
technology, government regulation and available financing or competition. The   
Company's estimate of future gross revenues and operating cash flows assumes    
that the Company will successfully develop its products. As a result of the     
pending Asset Sales discussed above and the valuations completed for the year   
ended December 31, 2000, the Company reduced the net carrying value of goodwill 
and other intangibles by $1,897,249 and net property and equipment by           
$16,077,794.                                                                    

LIQUIDITY AND CAPITAL RESOURCES                                                 

   On December 31, 2000 we had cash and cash equivalents of $642,554
compared to $2,990,300 at December 31, 1999. For the year ended December 31,    
2000, net cash used in operating activities of $14,353,839 and net cash used in 
investing activities, for capital expenditures, of $2,389,851 were provided by  
financing activities of $14,395,944.

       The Company has incurred a net loss of $40,983,720 for the year ended
December 31, 2000 and has an accumulated deficit of $83,047,170 since inception.
The Company has principally funded operations and plant and equipment           
expenditures from proceeds from public and private sales of equity as well as   
through the Asset Sales, discussed above. The Company has also borrowed funds   
under short and long-term borrowing arrangements. As of December 31, 2000, we   
had net borrowings of $951,005 in the revolving line of credit, with Texas State
Bank, secured by accounts receivable; a long term note payable of $94,095 to    
Eastern Idaho Economic, secured by an irrevocable letter of credit, with monthly
principal and interest payments of $2,213; a note payable of 13,929,874 to Texas
State Bank secured by substantially all of the assets of the company, with      
monthly installments of approximately $154,379, exclusive of capital lease      
transactions for equipment; a promissory note of $900,000 to NeoRx Corporation  
due in full by April 20, 2001; and a note payable to William Nicholson, the     
former chairman of the board, in the amount of $1,145,000.                      

     Subsequent to the close of the asset sales to NeoRx Corporation and
Imagyn Medical, Inc., in April and May of 2001, International Isotopes and Texas
State Bank cooperated to restructure several of the notes and loans established 
for the company. A balance limit on the company's main commercial loan was      
reduced from $15,000,000 to $7,750,000 with an interest rate of 9.6% per annum  
and all principal and interest payments were suspended until the loan reaches   
maturity on January 27, 2002. The company's previous $5 million line of credit  
note was reduced to a $1 million line, also with an interest rate 9.6% per      
annum. Principal and interest payments on the line of credit have also been     
deferred until the maturity date of April 27, 2002. Immediately after closing   
approximately $400,000 was drawn against this line of credit to reduce the      
commercial loan to the limited amount of $7,750,000 and address miscellaneous   
legal expenses and payments made by Texas State Bank on the company's behalf.   
The balance of this line of credit is to be used to support the continuing cash 
needs of the company. Texas State Bank also opened a new $500,000 commercial    
line of credit with an interest rate of 9.6% per annum to support the interim   
operations of the Shady Oaks/LINAC facility pending the completion of the sale  
of that property and equipment. Principal and interest payments on this line of 
credit were also deferred until January 27, 2002. Funds from the closing were   
also used to pay $348,000 of the $1,145,000 note payable to William Nicholson,  
the former Chairman of the Board. The balance due Mr. Nicholson is $797,000 plus
accrued interest.                                                               

       In February 2000 we completed a private placement of common stock for
proceeds of $5,378,177, net of fees. In June 2000 we completed a private        
placement of non-voting, 7% cumulative, redeemable, convertible, preferred stock
with proceeds of approximately $9,400,000, net of fees.                         

RESULTS OF OPERATIONS                                                           

YEAR ENDED DECEMBER 31, 2000 COMPARED TO YEAR ENDED DECEMBER 31, 1999           

REVENUES                                                      

Total revenues were $6,277,065 in 2000 as compared to $3,689,524 in 1999, an    
increase of $2,587,541 or 70.01%. The majority of the increase was related to   
product sales totaling $5,407,065 in 2000 as compared to $2,775,696 for 1999, an
increase of $2,631,369 or 94.8%. The increase in product revenue is primarily   
attributable to the sale of brachytherapy seeds initiated in 2000. Product      
developmental income, related to ongoing product development contracts, was     
$870,000 in 2000 as compared to $206,038 for 1999, an increase of $663,962 or   
322.3%. The increase in product development income is attributed to the increase
in development contract revenues from a $1.3 million contract with NeoRx. The   
increases in sales, as discussed above, were offset by a one-time sale of our   
accelerator components in 1999 totaling $707,790 with no comparable revenue in  
2000. The decrease in gross profit from $838,574 in 1999 to a negative          
$7,185,944 in 2000 is attributed to the Company increasing its production       
capacity in anticipation of increased future production levels and manufacturing
activities as well as increased costs associated with the product development   
contract which was suspended in December 2000.

COST OF REVENUES                                              

       Cost of revenues included $11,530,234 for radioisotope sales for 2000
as compared to $2,274,029 for 1999. The increase of $9,256,205 is primarily     
attributable to the start-up and initial automation of brachytherapy seed       
manufacturing during 2000. Cost of development income was $1,932,775 for 2000 as
compared to $2,631 for 1999. This increase is attributable to the of costs      
associated with the NeoRx contract. Cost of accelerator components sold was $0  
for 2000 as compared to $574,290 for 1999. The decrease in the cost of          
accelerator components sold was due to the one time sale of the accelerator     
components in 1999.                                                             

OPERATING COSTS AND EXPENSES                                  

       Operating expense for 2000 was $31,408,321 as compared to $14,610,731
in 1999, an increase of $16,797,590 or 115%. Impairment losses recorded during  
2000 accounted for $17,975,043 of the total increase. General and administrative
expenses for 2000 were $7,808,770 as compared to $4,347,395 for 1999, an        
increase of $3,461,375 or 79.6%. The increase in general, administrative and    
consulting expense was attributable to increases in personnel for production,   
marketing, quality control, environmental health and safety, and administrative 
personnel as the Company expanded its organizational structure and began limited
production operations. Other increases in operating expenses included increased 
insurance for property, general and product liability, license fees, supplies,  
materials related to manufacturing and increased depreciation expense as more   
equipment and facilities commenced operations. The increases as discussed above 
were partially off-set by a decrease in salaries, contract labor and product    
development expense which was $5,135,477 in 2000 as compared to $9,471,761 in   
1999, a decrease of $4,336,284. Product development expenses are costs          
associated with the development and manufacturing of test products prior to     
commercial production. The decrease in Salaries, contract labor and product     
development expense is attributed to the Company's curtailment of new product   
development. Sales and marketing expense for 2000 was $489,031 as compared to   
$791,575 for 1999, a decrease of $302,544 or 38.2%. The decrease in sales and   
marketing expenses in 2000 was due to a reduction in the scope of our marketing 
effort.                                                                         

OTHER INCOME (EXPENSE)                                        

  Other income (expense) for 2000 consisted of interest income and
interest expense. Interest expense was $2,525,376 in 2000 as compared to        
$567,986 in 1999, an increase of $1,957,390. The increase is due to interest    
during 2000 being expensed during the entire year rather than partially         
capitalized since the construction of the manufacturing facilities and related  
equipment had been completed. The Company capitalized interest costs of $-0- in 
2000 and $1,114,616 in 1999.                                                    

         Interest income was $135,921 in 2000 as compared to $242,537 in 1999, a
decrease of $106,616. The decrease in interest income is attributable to a      
reduction in the invested funds available from various private placements which 
were used to fund the Company's facilities construction, equipment purchases and
operations.                                                                     

YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998           

REVENUES                                                      

         Revenues for 1999 were $3,689,524 as compared to $2,009,165 in 1998, an
increase of $1,680,359. Product sales were $2,775,696 for 1999 as compared to   
$1,422,711 for 1998, an increase of $1,352,985. I(4), a wholly owned subsidiary,
provided $950,229 of this increase while initial sales of brachytherapy seeds   
provided an additional $402,738 during 1999. Product developmental income,      
related to our ongoing product development contracts, was $206,038 for 1999 as  
compared to $522,000 for 1998, a decrease of $315,962. The decrease was related 
to our emphasis on brachytherapy seed manufacturing as opposed to outside       
product development. Sales of our accelerator components were $707,790 for 1999 
as compared to $64,454 for 1998, an increase of $643,336. Sales of accelerator  
components acquired from the State of Texas increased due to increased efforts  
to market the components.

COST OF REVENUES                                              

         Cost of revenues included $2,274,029 for radioisotope sales for 1999 as
compared to $1,035,517 for 1998. The increase of $1,238,512 is attributable to  
increased sales from I(4), and initial sales of brachytherapy seeds during 1999.
Cost of development income was $2,631 for 1999 as compared to $62,830 for 1998. 
This decrease is attributable to our emphasis on brachytherapy seed             
manufacturing as opposed to outside product development. Cost of accelerator    
components sold was $574,290 for 1999 as compared to $32,227 for 1998. The      
increase in the cost of accelerator components sold was due to the increase in  
accelerator components sold and the write off of costs associated with          
non-marketable components.                                                      

OPERATING COSTS AND EXPENSES                                  

         Operating expense for 1999 was $14,610,731 as compared to $6,537,948 in
1998, an increase of $8,072,783 or 123%. Product development costs accounted for
$6,151,320 of the total increase. General and administrative expenses for 1999  
were $4,347,395 as compared to $3,553,669 for 1998, a 22.3% increase, and       
salaries and wages increased by $1,033,692, both as a result of increased       
facilities expenses and personnel additions as required for production          
activities. Research and development expenses, included in operating expenses   
above, were $406,651 in 1999 as compared to $281,706 in 1998 as a result of     
developing processes related to medical devices. Product development expense was
$6,976,589 in 1999 as compared to $825,269 in 1998. Product development expenses
are costs associated with the development and manufacturing of test products    
prior to commercial production. Sales and marketing expense for 1999 was        
$791,575 as compared to $697,530 for 1998.                                      

OTHER INCOME (EXPENSE)                                        

     Other income (expense) during 1999 consisted of interest income and
interest expense. Interest expense increased during 1999 due to interest for the
fourth quarter of 1999 being expensed rather than capitalized since the         
construction of the manufacturing facilities and related equipment had been     
completed. The Company capitalized interest costs of $1,114,616 in 1999 and     
$607,395 in 1998.                                                               

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997           

REVENUES                                                      

       Revenues for 1998 were $2,009,165 as compared to $135,765 in 1997, an
increase of $1,873,400, a thirteen fold increase. Product sales were $1,422,711 
for 1998 as compared to $-0- for 1997. The purchase of I(4) during 1998 provided
the increase in radioisotope sales as our Denton, Texas facilities were still in
the development stage. Product developmental income, related to our ongoing     
product development contracts, was $522,000 for 1998 as compared to $-0- for    
1997. Sales of our accelerator components were $64,454 for 1998 as compared to  
$135,765 for 1997. Sales of accelerator components acquired from the State of   
Texas decreased due to the long lead-time required to market this type of       
equipment.                                                                      

COST OF REVENUES                                              

         Cost of revenues included $1,035,517 for radioisotope sales for 1998 as
compared to $-0- for 1997. The increase was attributable primarily to the       
acquisition of I(4), which provided us with our first product sales. Cost of    
development income was $62,830 for 1998 as compared to $-0- for 1997. This      
increase was attributable to our ongoing product development contracts that were
signed in 1998. Cost of accelerator components sold was $32,227 for 1998 as     
compared to $79,287 for 1997. The decrease in the cost of accelerator components
sold was due to the decrease in accelerator components sold.                    

OPERATING COSTS AND EXPENSES                                  

        Operating expense for 1998 was $6,537,948 as compared to $2,118,334 in
1997, exclusive of $2,397,500 in employee incentive compensation, an increase of
$4,419,614 or 209%. The acquisition of I(4) provided $826,629 of the total      
increase. General and administrative expenses for 1998 were $3,553,669 as

compared to $1,125,752 for 1997, a 216% increase, and salaries and wages        
increased by $536,752, both as a result of increased activities and personnel   
additions in preparation of going into production. Research and development     
expenses included in operating expenses above, were $281,706 in 1998 as compared
to $0 in 1997 as a result of developing processes related to medical devices.   
Product development expense was $825,269 in 1998 as compared to $0 in 1997.     
Product development expenses are costs associated with the development and      
manufacturing of test products prior to commercial production. Sales and        
marketing expense for 1998 was $697,530 as compared to $-0- for 1997. Employee  
incentive compensation, which was incurred in 1997 due to stock options issued  
prior to the initial public offering, was not incurred in 1998.                 

OTHER INCOME (EXPENSE)                                        

    Other income (expense) during 1998 consisted primarily of interest
income, interest expense and donation of assets held for sale. Interest expense 
decreased during 1998 due primarily to an increase in the amounts capitalized.  
The Company capitalized interest costs of $607,395 in 1998 and $24,934 in 1997. 

FORWARD LOOKING INFORMATION AND RISK FACTORS                                    

         The Company or its representatives may make forward looking statements,
oral or written, including statements in this Report's Management's Discussion  
and Analysis of Financial Condition and Results of Operations, press releases   
and filings with the Commission, regarding estimated future operating results,  
planned capital expenditures (including the amount and nature thereof) and the  
Company's financing plans, if any, related thereto, and other plans and         
objectives for future operations. There can be no assurance that the actual     
results or developments anticipated by the Company will be realized or, even if 
substantially realized, that they will have the expected effects on its business
or operations. Among the factors that could cause actual results to differ      
materially from the Company's expectations are general economic conditions,     
competition, government regulations and other factors set forth among the risk  
factors noted below or in the description of the Company's business in Item 1 of
this Report, as well as factors contained in the Company's other securities     
filings.                                                                        

        Generally, forward looking statements include words or phrases such as
"management believes," the "Company anticipates," the "Company expects" and     
words and phrases of similar import. Forward looking statements are made        
pursuant to the Private Securities Litigation Reform Act of 1995.               

         All subsequent oral and written forward looking statements attributable
to the Company or persons acting on its behalf are expressly qualified in their 
entirety by these factors. The Company assumes no obligation to update any of   
these statements.                                                               

       INTERNATIONAL ISOTOPES HAS INCURRED AND MAY CONTINUE TO INCUR LOSSES.
The Company has net losses for each fiscal period since its inception. From     
inception (in November 1995) through December 31, 2000 we had generated         
$12,886,621 in revenues and had accumulated a deficit (including preferred stock
dividends and returns) in the amount of $83,047,170. The Company's history of   
operating losses has resulted in continued dependence upon additional external  
financing. Management's plans regarding its liquidity involved the successful   
execution of its 2000 business plan, including the successful commercialization 
of our products. We were unable to obtain the additional funds necessary to fund
operations, complete the commissioning of the LINAC, and meet debt service      
requirements. Subsequent to the sale of the Radiopharmaceutical Manufacturing   
Facility, the Seed Business and the LINAC, we anticipate that the ongoing       
operations, consisting solely of I(4), will continue to incur net operating     
losses and negative cash flows for the foreseeable future and may never be      
profitable.                                                                     

     WE WILL NEED ADDITIONAL FINANCING TO CONTINUE OPERATIONS. In December
1998 and January 1999 we raised approximately $11.4 million through a private   
placement of our equity, net of issuance costs. In April 1999 we initiated a    
private placement of securities resulting in additional equity of $8,115,852. In
May 1999, we

completed a private placement of $10,000,000 in non-voting, 5% cumulative,      
redeemable, convertible preferred stock, which was funded $5,000,000 in May and 
$5,000,000 in October 1999. We raised an additional $5,400,000 in February 2000 
through a private placement of our common stock. On June 15, 2000 we completed a
private placement of $10,000,000 in non-voting, 7% cumulative, redeemable,      
convertible preferred stock. However, substantial additional funds were         
necessary to enter into manufacturing contracts, expand finished pharmaceutical 
manufacturing, increase radioisotope production, continue research and          
development relating to the application of our technology, and complete the FDA 
approval process for our manufacturing and processing facilities. We had        
intended to seek additional capital through public or private sales of our      
securities, including equity or debt securities, in order to fund our           
activities. However, we were unsuccessful in these efforts. As a result, we     
agreed to sell certain assets in an effort to repay creditors to the extent     
possible and maximize shareholder value.                                        

     We anticipate that our remaining operations, I(4), will continue to
incur losses throughout the remainder of 2001. As such, the ability of the      
Company to continue is dependant on our ability to achieve additional funding   
from third parties. If we are unable to secure sufficient funds, it may         
adversely affect our ability to continue as a viable entity. There can be no    
assurance that we will be able to obtain additional financing or obtain         
financing on terms acceptable to the Company.                                   

    WE WILL CONTINUE TO BE DEPENDENT UPON OUR REMAINING FACILITIES AND
EQUIPMENT TO FUNCTION PROPERLY IN ORDER TO PROVIDE CONSISTENT, TIMELY SHIPMENTS 
OF PRODUCTS THAT MEET OUR CUSTOMERS' SPECIFICATIONS. If we experience equipment 
failures or breakdowns we may be unable to satisfy our customers, which could   
result in the cancellation of contracts and the loss of revenues.               

  OUR DOE CONTRACT IS SHORT TERM AND SUBJECT TO RENEGOTIATION. The
Company has a contract with the DOE to provide contract labor services for      
operations of the DOE hot cells and access to the DOE reactors for continued    
radioisotope production. However, these contracts expire September 30, 2001 and 
it is likely that the hot cell labor services will not be continued after that  
time. Without continued hot cell access the commercial isotope production in the
reactor would have to be suspended until I(4) can reestablish isotope processing
capability in its Idaho Falls facility.                                         

       OPERATIONAL HAZARDS (I.E., SPILLS, FAULTS, VENTILATION FAILURE, ETC.)
COULD RESULT IN THE SPREAD OF CONTAMINATION WITHIN OUR IDAHO FACILITY AND       
REQUIRE ADDITIONAL FUNDING TO CORRECT. An irrevocable, automatic renewable      
letter of credit against a $130,000 Certificate of Deposit at Texas State Bank  
has been used to provide the financial assurance required by the Nuclear        
Regulatory Commission for the Idaho facility license.                           

 TECHNOLOGY PROBABILITY AND EARLY STAGE PRODUCTION. Radioisotope
production is a well-established process but relies upon operation of a         
Department of Energy reactor. Continued access to the reactor is not guaranteed.
Additionally, reactor operation issues could adversely effect radioisotope      
production. The gemstone processing and medical flood source contract           
manufacturing operations are new processes and are likely to encounter some     
early stage process difficulties.                                               

    GOVERNMENT REGULATION COULD ADVERSELY AFFECT OUR BUSINESS. Certain
radioisotopes manufactured by I(4) are subject to the U.S. Nuclear Regulatory   
Commission regulations. To the extent these regulations are or become           
burdensome, our business development could be adversely affected. Medical flood 
sources are regulated by the Texas Department of Health as a sealed source and  
the I(4) manufacturing facility is registered with the Food and Drug            
Administration as a medical device manufacturing facility.                      

  WE ARE DEPENDENT UPON KEY PERSONNEL AND CONSULTANTS. Our ongoing
operations will be dependent on Steve T. Laflin, president and general manager  
of I(4), and as of August 2001, president and CEO of the ongoing operations of  
I(3). We are highly dependent upon this person and the loss of this individual  
would have a material adverse effect on us. There is no assurance we will be    
able to retain our existing personnel or attract additional qualified employees.

  WE ARE DEPENDENT ON VARIOUS THIRD PARTIES IN CONNECTION WITH OUR
BUSINESS OPERATIONS. The production of isotopes by I(4) is dependent upon the   
Department of Energy, who controls the reactor and laboratory operations, and   
its key operating contractor, who performs the day to day operations of those   
associated facilities. The gemstone production is tied to an exclusive agreement
with Topaz Group, Inc and medical flood source manufacturing is tied to an      
exclusive contract with RadQual LLC.                                            

        WE ARE SUBJECT TO COMPETITION FROM STRONGER COMPETITORS IN EACH OF OUR
BUSINESS OPERATIONS. Each of the various production and manufacturing areas of  
I(4) has distinct features to competition. Reactor produced radioisotopes are   
supplied by many reactor facilities around the world including two domestic     
sources (the University of Missouri Research Reactor and the High Flux Isotope  
Reactor). Most radioisotopes from reactors are produced in bulk form, are very  
competitively priced, and offer small margins for profit. Medical flood sources 
are being produced by several other manufacturers in the U.S. and overseas.     
There are several producers of Gemstone who utilize the irradiation process for 
color enhancement and engage the services of other companies to provide pre and 
post irradiation processing. Most of these entities have substantially greater  
financial, technical, manufacturing, marketing, distribution and/or other       
resources than the Company. Accordingly, other companies may succeed in         
developing products earlier, or that are safer or more effective than those we  
propose to develop, and in obtaining FDA clearances for such products before our
customers obtain approval.                                                      

       AS WE SUCCESSFULLY DEVELOP OUR PRODUCTS, WE MAY BE EXPOSED TO PRODUCT
LIABILITY CLAIMS. We might also be required to indemnify affiliates against any 
product liability claims incurred by them as a result of products developed by  
the Company under licenses granted by these affiliates. We believe we currently 
carry adequate product liability insurance; however, we cannot assure you that  
we will in the future be able to obtain sufficient amounts of insurance to      
protect us against such liability at a reasonable cost. If we experience an     
uninsured or inadequately insured product liability claim, our business and     
financial condition could be materially adversely affected.                     

        HOLDERS OF OUR SERIES A AND SERIES B PREFERRED STOCK HAVE THE RIGHT TO
CONVERT THEIR PREFERRED STOCK INTO COMMON STOCK AND TO RECEIVE DIVIDENDS PAYABLE
IN COMMON STOCK CAUSING SUBSTANTIAL DILUTION TO COMMON SHAREHOLDERS AND         
ULTIMATELY RESULTING IN CONTROL OF THE COMPANY BY THE CURRENT PREFERRED HOLDERS.
The holders of our Series A and Series B preferred stock have the right to      
convert the principle amount of their shares into common stock at a conversion  
price of $2.00 per share, subject to adjustment in the case of stock splits or  
dividends. These holders also will continue to receive shares of common stock in
payment of their preferred dividends (5% for the Series A and 7% for the Series 
B) because the Company does not have funds to pay the dividends in cash. Since  
these stock dividends are payable based on the market price of the Company's    
common stock, which is currently only pennies per share, the preferred holders  
will most likely accumulate enough common shares through their dividend,        
conversion and redemption rights to control the Company's board of directors and
management. Moreover, the Series A shares are redeemable in May and October 2002
and the Series B shares are redeemable in May 2003 in cash or stock at the then 
current market price. If the Company had to redeem the preferred stock using    
common stock issuable at the current market price, this would result in the     
preferred shareholders owning more that 90% of the outstanding common stock.    

NEW ACCOUNTING STANDARDS                                                        

In July 2001, the Financial Accounting Standards Board (FASB) issued Statement  
of Financial Accounting Standards (SFAS) No. 141, Business Combinations, and    
SFAS No. 142 Goodwill and Other Intangible Assets. SFAS No. 141 requires that   
the purchase method of accounting be used and establishes new standards on the  
recognition of certain identifiable intangible assets separate from goodwill for
all business combinations initiated after June 30, 2001. SFAS No. 142 will      
require that goodwill and intangible assets with indefinite useful lives no     
longer be amortized, but instead tested for impairment at least annually. SFAS  
No. 142 will also require that intangible assets with definite useful lives be  
amortized over their respective estimated useful lives to their estimated       
residual values.

We are required to adopt the provisions of SFAS No. 141 immediately and SFAS No.
142 effective January 1, 2002, except that goodwill and intangible assets       
determined to have an indefinite useful life that are acquired in a purchase    
business combination completed after June 30, 2001 will not be amortized, but   
will continue to be evaluated for impairment in accordance with the accounting  
literature in effect prior to the issuance of SFAS No. 142. Goodwill and        
intangible assets acquired in business combinations completed before July 1,    
2001 will continue to be amortized through December 31, 2001. At December 31,   
2000, the carrying amount of our unamortized goodwill and intangibles was zero  
as a result of the impairment charge recorded.                                  

In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement    
Obligations." This Standard is effective for fiscal years beginning after June  
15, 2002, and provides accounting requirements for asset retirement obligations 
associated with tangible long-lived assets. We have not yet determined the      
effects of this Standard on our financial statements.                           

ITEM 7a. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK              

         The Company is exposed to market risk from changes in interest rates on
its long-term debt. The Company's exposure to interest rate risk relates to     
variable rate loans that are benchmarked to US bank prime lending rates. The    
Company does not use derivative financial instruments to manage overall         
borrowing costs or reduce exposure to adverse fluctuations in interest rates.   
The impact on the Company's borrowing costs and cash flows of a one-point       
interest rate change on the outstanding balance of the variable rate debt as of 
December 31, 2000 would be approximately $157,809.

directors. During 2000, the Company suspended payment of the $500 fee. The      
Company continues to reimburse directors for all expenses incurred in connection
with their activities as directors. Non-employee directors and employee         
directors of the Company are entitled to receive certain stock option awards    
under the Company's 2000 Amended and Restated Long Term Incentive Plan.

Employee directors of the Company do not receive additional

EMPLOYMENT AGREEMENTS

months of his base compensation.                                                

     In June 2000, the Company entered into an Employment Agreement with
Paul E. Landers to serve as the Company's Chief Financial Officer. The Agreement
provided for a term of two years with base compensation equal to $135,000

the Compensation Committee. Mr. Landers received 60,000 stock options to        
purchase shares of the Company's Common Stock and if certain Company performance
goals were met he was entitled to a stock grant of an additional 40,000 shares.

granted. Mr. Landers has informed the Board of Directors that he intends to     
resign as Chief Financial Office effective upon the filing with the SEC of this 
form 10-K. Mr. Landers will continue to serve as a member of the Board of       
Directors of the Company. In accordance with his Employment Agreement, Mr.      
Landers was paid a severance benefit equal to six months of his base salary.    

      In April 2001, the Company entered into an Employment Agreement with
Steve Laflin to serve as the Company's new President and Chief Executive Officer
upon Mr. Camp's resignation and Mr. Laflin's election to the President and CEO  
position by the Board of Directors. Mr. Laflin was elected President and Chief

is entitled to bonus compensation at the discretion of the Board of Directors   
and the Compensation Committee. In connection with his Employment Agreement, Mr.
Laflin was granted stock options to purchase 1,000,000 shares of the Company's  
Common Stock at an exercise price of $.076 per share, the fair market value of  
the Company's Common Stock on the date of grant. Of this amount, 500,000 options
vested immediately with the remainder vesting in two equal installments of      
250,000 in April 2002 and April 2003, respectively.                             

REPORT ON EXECUTIVE COMPENSATION                                                

GENERAL                                                                         

        The Compensation Committee currently consists of three members, one of
which serves or served as an executive officer of the Company. No executive     
officer of the Company serves or served on the compensation committee of another
entity and no executive officer of the Company serves or served as a director of
another entity which has or had an executive officer serving on the board of    
directors of the Company.                                                       

         Decisions on compensation of the Company's executive officers generally
are made by the Compensation Committee of the Board, subject to review and      
approval by the full Board of Directors. Decisions with respect to awards under 
the Company's Long Term Incentive Plan are also made by the Compensation        
Committee, subject to review and approval by the Board of Directors. Set forth  
below is a report prepared by Messrs. McCormack, LeMaistre and Camp in their    
capacity as the Compensation Committee addressing the Company's compensation    
policies for the fiscal year 2000 as they affected the Company's executive      
officers, including the Company's Chief Executive Officer, David M. Camp.       

  The Compensation Committee's executive compensation policies are
designed to provide competitive levels of compensation that integrate pay with  
the Company's annual and long term performance goals, review above average      
corporate performance, recognize initiative and achievements, and assist the    
Company in attracting and retaining qualified executives. Targeted levels of    
total executive compensation are generally set at levels that the Compensation  
Committee believes to be consistent with others in the Company's industry,      
although actual compensation levels in any particular year may be above or below
those of the Company's competitors, depending upon the Company's performance.   

       The Compensation Committee is mindful of grants or awards made to the
Company's executive officers under the Company's Long Term Incentive Plan. The  
Compensation Committee endorses the position that stock ownership by management 
and stock based performance compensation arrangements are beneficial in aligning

management's and shareholders' interest in the enhancement of shareholder value.
Thus, the Compensation Committee takes into account the stock based elements in 
designing the compensation packages of the Company's executive officers.        

        The principal components of the Company's non-stock based compensation
program are base salary and bonus. Bonuses are at the discretion of the         
Compensation Committee and the board, based on performance criteria and         
production. No bonus or other incentive based compensation was paid in fiscal   
year 2000.                                                                      

FISCAL 2000 CHIEF EXECUTIVE OFFICER COMPENSATION                                

     Dr. Camp's compensation for fiscal year 2000 as President and Chief
Executive Officer of the Company consisted solely of his base salary. No bonus  
or other non-stock incentive based compensation was provided. the Compensation  
Committee believes that Dr. Camp's compensation package is set at a level that  
is consistent with others in the Company's industry. Dr. Camp is a member of the
Compensation Committee but does not participate in the Compensation Committee's 
decision regarding his compensation.                                            

                                    Submitted by the Compensation Committee of
                the Board of Directors

INDEPENDENT AUDITORS' REPORT

The Board of Directors                                                          
International Isotopes Inc.:                                                    

We have audited the accompanying consolidated balance sheets of International   
Isotopes Inc. and subsidiaries as of December 31, 2000 and 1999, and the related
consolidated statements of operations, stockholders' equity (deficit) and cash  
flows for each of the years in the three-year period ended December 31, 2000.   
These consolidated financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these consolidated   
financial statements based on our audits.                                       

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. 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 our audits provide a reasonable    
basis for our opinion.                                                          

In our opinion, the consolidated financial statements referred to above present 
fairly, in all material respects, the financial position of International       
Isotopes Inc. and subsidiaries as of December 31, 2000 and 1999, and the results
of its operations and its cash flows for each of the years in the three-year    
period ended December 31, 2000 in conformity with accounting principles         
generally accepted in the United States of America.                             

The accompanying consolidated financial statements have been prepared assuming  
that the Company will continue as a going concern. As discussed in note 2 to the
consolidated financial statements, the Company has suffered recurring losses    
from operations and has net capital deficiency that raises substantial doubt    
about its ability to continue as a going concern. Management's plan in regard to
these matters are also described in note 2. The consolidated financial          
statements do not include any adjustments that might result from the outcome of 
this uncertainty.                                                               

April 27, 2001, except for Note 11                                              
as to which the date is June 6, 2001                                            
Dallas, Texas

 INTERNATIONAL ISOTOPES INC AND SUBSIDIARIES

Notes to Consolidated Financial Statements
December 31, 2000 and 1999

(1)      DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION                      

       International Isotopes Inc (the Company) was incorporated in Texas in
         November 1995. The Company acquired the technology, proprietary designs
   and intellectual property for the design and assembly of a proton
     linear accelerator (LINAC) to produce radioisotopes used in nuclear
         medicine for the detection and treatment of various forms of cancer and
      other diseases. The Company also owns 100% of the outstanding common
       shares of Gazelle Realty, Inc. and International Isotopes Idaho, Inc.
  (I(4)). Gazelle Realty, Inc. owned 20 acres of land on which the
      facility for the LINAC has been constructed and 1.6 acres of land on
       which the administration, manufacturing, and research and development
  building was constructed. During 1997, all the property owned by
Gazelle Realty, Inc. was transferred to the Company.          

   Prior to initial production in late 1999, the Company had devoted
       substantially all of its efforts, since inception, to the acquisition
and construction of the LINAC project and related assets,     
pharmaceutical production and to raising capital and other    
     organizational activities. The operating revenues to date have been
         limited to the sales of accelerator components purchased from the State
of Texas, product development income, initial sales of I-125  
       brachytherapy seeds and sales of reactor produced products from I(4).
        Additionally, the Company has derived operating capital from the sales
    of assets. The Company has financed its operations in part through
    private placements of its equity securities and its initial public
offering (the "Offering") which occurred on August 19, 1997.  

   The consolidated financial statements include the accounts of the
    Company and its wholly owned subsidiaries Gazelle Realty, Inc. and
 International Isotopes Idaho, Inc. All significant intercompany
  accounts and transactions have been eliminated in consolidation.
     Certain reclassifications were made to prior years' presentation to
conform to the current year presentation.                     

(2)      SALE OF ASSETS, LIQUIDITY AND GOING CONCERN                            

       The Company has an accumulated deficit of approximately $83.0 million
     since inception and has principally funded operations and plant and
         equipment expenditures from proceeds from public and private placements
     of equity and through the increase of short and long-term borrowing
     arrangements. In late 2000, the Company determined that it would be
     required to pursue strategic alternatives to sell certain assets in
order to continue operations.                                 

    On January 16, 2001, the Company completed the sale of the Woodrow
    Spencer office and warehouse facility located in Denton, Texas for
         proceeds of $950,000, less closing costs of $63,811. The facility had a
 net book value of $1,095,962 at December 31, 2000. Based on the
       anticipated sales proceeds, the Company recorded an impairment charge
      related to this facility in the amount of $209,773. The Company used
 the proceeds to reduce its revolving line of credit by $863,890
     (including accrued interest of $23,400) and fund operating expenses
with the remaining amounts.                                   

On April 20, 2001, the Company completed the sale of the      
 Radiopharmaceutical Manufacturing Facility to NeoRx Corporation
       ("NeoRx") for cash proceeds of $12.0 million and warrants to purchase
        800,000 shares of NeoRx common stock. The assets acquired by NeoRx had
        a net book value of $11,304,724 at December 31, 2000. The Company used
   the proceeds to repay net advances made by NeoRx in the amount of
        $861,060, reduce its note payable to a commercial lender by $1,296,469
         (including interest of $36,578), reduce its revolving line of credit by
        $2,614,023 (including accrued interest of $45,857), reduce its capital
lease obligations by $3,291,289, repay a portion of the

        note payable to William Nicholson, the former Chairman of the Board in
         the amount of approximately $348,000 and fund other operating expenses.

        On April 27, 2001, the Company completed the sale of its brachytherapy
      seed assets to Imagyn Medical Technologies, Inc. ("Imagyn") for cash
       proceeds of approximately $5.0 million. The assets acquired by Imagyn
       had a net book value of $5,416,294 at December 31, 2000. Based on the
       anticipated sales proceeds, the Company recorded an impairment charge
       of $416,294 related to these assets. The Company used the proceeds to
 repay advances and expenses incurred by Imagyn in the amount of
$108,786 and reduce its note payable to a commercial lender by
    $4,645,582 (including accrued interest of $25,768), reduce capital
       lease obligations by $145,632 and fund other operating expense in the
amount of $100,000.                                           

        In order to further reduce the Company's debt obligations, the Company
  plans to sell both the Shady Oaks/LINAC facility and property in
Waxahachie, Texas.                                            

   The Company is negotiating sell the Shady Oaks/LINAC radioisotope
         production facility. The Company estimates net proceeds of $7.7 million
        based on the most recent price offered by the potential buyer. The net
     book value of the Shady Oaks/LINAC were $23,053,925 at December 31,
     2000. Based on the anticipated sales price, the Company recorded an
        impairment charge as of December 31, 2000 in the amount of $15,889,765
      to write down the assets to estimated fair value less costs to sell.

     The property in Waxahachie, Texas has a net book value of $409,531.
 Based on a recent external appraisal, the Company believes that
      proceeds from the sale of this property will be in excess of its net
book value.                                                   

         As part of acquiring the LINAC from the State of Texas in 1996, certain
         components were received which were not used in the construction of the
        currently assembled LINAC. The Company had planned to either use these
         components in the construction of a second LINAC or sale the assets. As
         part of the Company's plan to divest of the assets discussed above, the
  Company determined that it would attempt to also sell its excess
     components. The Company completed an analysis of the components and
  determined that certain assets had no market value. As such, the
    Company recorded an impairment charge of $358,453 related to these
         assets. The remaining components have a net book value of approximately
       $320,000 and based on discussions with potential buyers, these assets
     do not appear to be impaired. The Company reclassified these assets
from other assets to assets held for sale in the accompanying 
consolidated financial statements at December 31, 2000.       

         A summary of the impairment charge recorded as of December 31, 2000, is
as follows:                                                                     

                                                                [Download Table]

                                                                -----------
                                                                $17,975,043
                                                                ===========

     Subsequent to the sales of assets described above, the Company will
        consist solely of the I(4) Idaho operations and the size and nature of
the business is substantially less in scope. While the Company
        anticipates being able to further reduce remaining debt obligations by
        approximately $8 million with additional asset sales, the Company does
not expect to generate sufficient cash flows to meet

Notes to Consolidated Financial Statements
December 31, 2000 and 1999

   operational needs during 2001 and the viability of the Company is
     dependent on its ability to secure additional financing or generate
       sufficient cash flows from operations. There can be no assurance that
    the Company will be able to raise additional capital, complete the
        remaining asset sales for the proceeds currently estimated or generate
      sufficient cash flows from operations to sustain the Company. If the
Company is unable to obtain additional financing, complete the
      remaining asset sales for sufficient proceeds or generate sufficient
cash flows from operations, the Company's operations would be 
      significantly curtailed. These factors raise substantial doubt about
        the Company's ability to continue as a going concern. The consolidated
       financial statements do not include any adjustments that might result
from the outcome of this uncertainty.                         

(3)      SIGNIFICANT ACCOUNTING POLICIES                                        

(a)      Financial Instruments and Cash Equivalents           

       The Company's financial instruments consist of cash
          equivalents, accounts receivable and payable and notes
              payable. The carrying value of these financial instruments
                 approximates fair value because of their short-term nature or
                because they bear interest at rates which approximate market
rates.                                      

               Cash equivalents of $162,525 and $2,652,241 at December 31,
                  2000 and 1999, respectively, consist of money market accounts.
                  For purposes of the consolidated statements of cash flows, the
                  Company considers all highly liquid financial instruments with
          original maturities of three months or less at date of
purchase to be cash equivalents.            

(b)      Property, Plant and Equipment                        

             The Company capitalized interest cost during construction
              periods of both its buildings and equipment. There were no
                  interest costs capitalized in 2000. Interest costs capitalized
in 1999 amounted to $1,114,616.             

             Depreciation on property, plant and equipment is computed
                 using the straight-line method over the estimated useful life
             of the asset. The ranges of estimated useful lives are as
follows:                                    

                                                                [Download Table]

Buildings                  39    
Plant assets               5 - 30
Computer equipment         5     
Furniture & fixtures       3 - 7 

(c)      Inventories                                          

                Inventories are carried at the lower of cost or market. Cost
      is determined using the first-in first out method.

(d)      Income Taxes                                         

                Income taxes are accounted for under the asset and liability
                  method. Deferred tax assets and liabilities are recognized for
           the future tax consequences attributable to differences
                between the financial statement carrying amounts of existing
             assets and liabilities and their respective tax bases and
             operating loss and tax credit carryforwards. Deferred tax
assets and liabilities

Notes to Consolidated Financial Statements
December 31, 2000 and 1999

             are measured using enacted tax rates expected to apply to
        taxable income in the years in which those temporary
            differences are expected to be recovered or settled. The
                effect on deferred tax assets and liabilities of a change in
                tax rate is recognized in income in the period that includes
the enactment date.                         

(e)      Use of Estimates                                     

                Management of the Company has made a number of estimates and
       assumptions relating to the reporting of assets and
           liabilities and the disclosure of contingent assets and
         liabilities at the date of the consolidated financial
            statements and reported amounts of revenues and expenses
             during the reporting period to prepare these consolidated
              financial statements in conformity with generally accepted
                 accounting principles. Actual results could differ from those
estimates.                                  

      (f)      Impairment of Long-Lived Assets and Long-Lived Assets to be
Disposed Of                                 

              Long-lived assets and certain identifiable intangibles are
         reviewed for impairment whenever events or changes in
               circumstances indicate that the carrying amount of an asset
               may not be recoverable. Recoverability of assets to be held
                and used is measured by comparison of the carrying amount of
                 an asset to future net cash flows expected to be generated by
                the asset. If such assets are considered to be impaired, the
                  impairment to be recognized is measured by the amount by which
                  the carrying amount of the assets exceed the fair value of the
                 assets. Assets to be disposed of are reported at the lower of
              the carrying amount or fair value less costs to sell. (See
note 2)                                     

(g)      Revenue Recognition                                  

                 Revenue is recognized when product development milestones are
                 accomplished, products are shipped and accelerator components
        are shipped. No warranty coverage or right of return
                 provisions are provided to customers. For certain fixed-price
contracts, revenue is recognized on the     
                 percentage-of-completion method, based on the percentage that
           contract costs incurred to date bear to total estimated
         contract costs after giving effect to the most recent
           estimates of total cost. The effect of changes to total
             estimated contract costs is recognized in the period such
               changes are determined. Provisions for estimated losses are
                made in the period in which the loss is determined. Unbilled
                receivables represent costs and related profits in excess of
           billings. Unbilled receivables were not billable at the
                  balance sheet date but are recoverable over the remaining life
         of the contract through billings that will be made in
accordance with contractual agreements.     

(h)      Stock Option Plan                                    

               The Company accounts for stock-based compensation using the
                  intrinsic-value based method and provides pro forma net income
             and pro forma earnings per share disclosures for employee
                 stock option grants as if the fair-value based method defined
in SFAS No. 123 had been applied.           

                 Under the intrinsic-value based method, if the exercise price
                of employee stock options equals or exceeds the market price
                 of the underlying stock on the date of grant, no compensation
              expense is recorded. Under the provisions of the Company's
             equity compensation plan, stock options cannot be granted
below market.

Notes to Consolidated Financial Statements
December 31, 2000 and 1999

(i)      Goodwill                                             

                  Goodwill represents the excess of the aggregate purchase price
                  over the fair value of net assets acquired and is amortized on
                  a straight-line basis over 77 months. The Company assesses the
                  recoverability of this intangible asset by determining whether
               the amortization of the goodwill balance over its remaining
               life can be recovered through undiscounted future operating
                cash flows of the acquired operation. The amount of goodwill
                 impairment, if any, is measured based on projected discounted
                 future operating cash flows compared to the carrying value of
                  goodwill. Goodwill impairment during 2000 resulted in a charge
to operations of $1,100,758 (See note 5).   

(j)      Net Loss Per Common Share-Basic and Diluted          

                 Basic loss per share is computed on the basis of the weighted
                average number of common shares outstanding during the year.
                 Diluted loss per share, which is computed on the basis of the
                weighted average number of common shares and all potentially
              dilutive common shares outstanding during the year, is the
                 same as basic loss per share for the years ended December 31,
                 2000, 1999 and 1998, as all common stock options and warrants
were anti-dilutive.                         

(k)      Comprehensive Income                                 

      Comprehensive income includes net income and other
                comprehensive income which is generally comprised of changes
                  in the fair value of available-for-sale marketable securities,
               foreign currency translation adjustments and adjustments to
              recognize additional minimum pension liabilities. For each
                period presented in the accompanying consolidated statements
               of operations, comprehensive loss and net loss are the same
amount.                                     

(l)      Reclassifications                                    

           Certain 1999 and 1998 amounts have been reclassified to
conform with the 2000 presentation.         

(4)      INVENTORIES                                                            

     Inventories consist of the following at December 31, 2000 and 1999:

                                                                [Download Table]

        The Company recorded inventory write-offs of $569,858 and $368,298 for
         the years ended December 31, 2000 and 1999, respectively. These amounts
         have been included in cost of products in the accompanying consolidated
financial statements.

Notes to Consolidated Financial Statements
December 31, 2000 and 1999

(5)      ACQUISITIONS                                                           

 On April 24, 1998, the Company completed the acquisition of MAC
      Isotopes, Inc. from its parent corporation, MACTEC, Inc., of Golden,
    Colorado, and then merged MAC Isotopes into International Isotopes
  Idaho Inc, a newly formed subsidiary of the Company. The Company
    exchanged $500,000 in cash and 159,416 shares of its common stock,
        valued at $3,173,973 for 100% of the stock in MAC Isotopes. MACTEC had
     the option to sell 50% of the shares back to the Company on each of
      April 23, 1999 and April 24, 2000 for a purchase price of $19.91 per
       share. If the Company does not repurchase the shares, Auric Partners,
         of which William Nicholson, a director of the Company, is a partner, is
     required to purchase the shares. If Auric purchases the shares, the
    Company is obligated to issue to Auric warrants to purchase common
      stock of the Company in sufficient quantity and at an exercise price
        that will compensate it for the difference between $19.91 and the then
current market price of the Company's stock.                  

        In April 1999, MACTEC exercised the right to sell 50% of the shares of
      common stock at a price of $19.91 per share. The Company facilitated
     the sale of common stock at the market price of $9.00 per share and
        paid MACTEC the difference of $10.91 per share or $869,559 in cash. In
  April 2000, the Company advanced to MACTEC $1,586,908, for final
      reimbursement for decreases in the market value of the common stock.
 The payments were recorded as a reduction to additional paid-in
       capital. In August 2000, MACTEC sold on open market the 79,708 shares
 of common stock and paid the excess proceeds of $320,466 to the
Company.                                                      

     As part of the Company's process of determining whether to continue
     operations, a detailed cash flow projection was performed for I(4).
        Based on these projections, the Company determined that the future net
        cash flows expected to be generated from these operations would not be
sufficient to recover the goodwill related to the MACTEC, Inc.
        acquisition. Accordingly, the Company recorded an impairment charge of
    $1,100,758 to write off the recorded goodwill balance that was not
expected to be recovered from future operations.              

(6)      PROPERTY, PLANT AND EQUIPMENT

         amounts would be due in full. Additionally, the Company has a revolving
        line of credit with a maximum availability of $5,000,000. The interest
        rate, currently 9.25%, is one percent over the prime rate as listed by
  the Wall Street Journal and resets every six months. The loan is
     secured by substantially all of the Company's assets and contains a
        $4,000,000 guarantee by I.L. Morgan, then Chairman of the Board. Terms
of this loan contain various restrictive covenants, including 
prohibition of additional liens existing on security interest,
     limitation on additional indebtedness, limitations on dividends and
      similar payments and prohibition of any mergers or acquisitions. The
      Company restructured this line of credit in 2001 reducing the amount
     available to $900,000. Additionally in 2001, the Company executed a
     second revolving line of credit with the same financial institution
         with a maximum availability of $500,000. The funds available under this
         line of credit are solely available to fund amounts required to operate
the Shady Oaks/LINAC facility.                                

     On December 4, 2000 and December 26, 2000, the Company executed two
        promissory notes with NeoRx for $500,000 and $400,000, respectively. A
         portion of the $500,000 paid to the Company is to be applied as payment
        in full of all outstanding amounts owed by NeoRx to the Company. These
     amounts were fully repaid in 2001 using proceeds from the Company's
sale of assets (note 2).                                      

   On August 3, 2000, the Company executed a loan agreement with the
      Eastern Idaho Economic Council for $100,000. Under the terms of this
        agreement, the loan bears interest at 3% and payments in the amount of
      $2,091 due monthly beginning October 15, 2000 and continuing through
       September 15, 2004. Additionally, the Company must maintain a minimum
        levels of employment in Eastern Idaho throughout the term of the note.
         As collateral for this loan, the Company executed an irrevocable letter
of credit with a bank.                                        

     In May 2000, the Company executed a promissory note with the former
   chairman of the Board in the amount of $1,000,000. The note bears
        interest at a rate of 9.6% and is due May 2001. In September 2000, the
         note was increased by $145,000 to $1,145,000. In 2001, the Company paid
        the former Chairman of the Board approximately $348,000, to reduce the
amount owed to $797,000 plus accrued interest.                

   The Company was not in compliance with several of the restrictive
      covenants of the above note payable to bank or the line of credit at
      December 31, 2000. As such, all debt other than that owed to Eastern
         Idaho Economic, has been classified as current as of December 31, 2000.

    accounting for the Plan and, accordingly, except for stock options
issued at less than quoted market value at date of issue, no

 accompanying consolidated financial statements. Had the Company
        determined compensation cost based on the fair value at the grant date
  for its stock options under SFAS No. 123, the Company's net loss

Notes to Consolidated Financial Statements
December 31, 2000 and 1999

        Preferred Stock and Redeemable Convertible Preferred Stock - Under the
       terms of the original Articles of Incorporation and By-Laws in effect
     at December 31, 1996, the Company was authorized to issue 5,000,000
    shares of Preferred Stock, par value $1.00 per share. No shares of
$1.00 par Preferred Stock were issued. Restated Articles of   
      Incorporation and By-Laws adopted by the Company effective March 20,
    1997, changed the par value of Preferred Stock to $.01 and revised
         certain voting rights. Under the Restated Articles of Incorporation and
       By-Laws, Preferred Stock may be issued in series from time to time at
     the discretion of the Board of Directors. The Board of Directors is
     authorized to set the distinguishing characteristics of each series
     prior to issuance, including the granting of limited or full voting
        rights, rights to payment of dividends and amounts payable in event of
liquidation, dissolution or winding up of the Company.        

    In May 1999 and October 1999, the Company issued a total of 10,000
       shares (5,000 in May 1999 and 5,000 in October 1999) of 5% cumulative
    redeemable convertible $0.01 par value $1,000 face value preferred
      stock ("Preferred Stock") together with 410,000 warrants to purchase
common stock at $11.86 per share, for aggregate proceeds of   
      $10,000,000, before issuance costs of $600,000. Dividends are 5% per
 annum payable in cash or common stock (at the Company's option)
      beginning October 15, 1999 for the May issuance and January 15, 2000
      for the October issuance and continuing quarterly thereafter through
     May 20, 2002 for the May 1999 issuance and October 15, 2002 for the
         October 1999 issuance. If paid in common stock, the number of shares is
       based on the average market price for the 10 trading days immediately
  preceding the dividend payment date (the "Average Price"). As of
         December 31, 1999, the Company had paid cash dividends on the Preferred
Stock of $102,736.                                            

        The Preferred Stock is convertible to common stock at $11.86 per share
        at issuance and the conversion price is reset at each dividend payment
       date to the then Average Price (with a floor of $7.00 per share and a
ceiling of $11.86 per share).                                 

       The Preferred Stock is mandatorily redeemable on May 20, 2002 for the
         May 1999 issuance and October 15, 2002 for the October 1999 issuance in
  cash or common stock at the then Average Price, at the Company's
      option. Early redemption may be required at the option of the holder
       under certain circumstances and may be exercised at the option of the
        Company under other circumstances. Mandatory redemption events include
        change in control, suspension or delisting from NASDAQ, the BSE or any
subsequent market on which the common stock is listed for five
 consecutive days, breach by the Company of any representations,
warranties or other conditions in the preferred stock purchase
         agreement, and other events. Warrants are exercisable at any time up to
     May 20, 2002 for the May 1999 issuance and October 15, 2002 for the
October 1999 issuance.                                        

        The warrants associated with the Preferred Stock were valued as of the
  dates issued. On May 20, 1999, 205,000 warrants were issued. The
  resulting value, using Black-Scholes model with the value of the
     underlying stock being $11.67, exercise price of $11.86, volatility
   rate of 60%, risk free rate of 5.6% and contractual life of three
  years, was $5.17 per warrant or $1,059,850. On October 15, 1999,
  another 205,000 warrants were issued. The resulting value, using
         Black-Scholes model with the value of the underlying stock being $5.63,
     exercise price of $11.86, volatility rate of 60%, risk free rate of
    5.6% and contractual life of three years, was $1.32 per warrant or
$270,600. The total warrant value, $1,330,450, was recorded to
     additional paid-in capital and is being accreted to Preferred Stock
      from the date of issuance to the date of mandatory redemption of the
Preferred Stock.                                              

     After consideration of the warrant value, the Preferred Stock has a
        "beneficial conversion feature" of $1,930,450 that has been recognized
        as an additional return to the holders through a charge to accumulated
deficit and an increase to additional paid-in capital.

       circumstances. Mandatory redemption events include change in control,
       suspension or delisting from NASDAQ, the BSE or any subsequent market
       on which the common stock is listed for five consecutive days, breach
       by the Company of any representations, warranties or other conditions
         in the preferred stock purchase agreement, and other events. The Series
         B Preferred Stock is convertible to common stock at $4.00 per share and
      the warrants are exercisable at any time up to June 1, 2003 at $4.00
per share.                                                    

       The Company assigned an aggregate value of $3,283,582 to the warrants
    ($1.31 per share) using an option pricing model with the following
        assumptions: market value of underlying stock of $4.50 on the issuance
       date, exercise price of $4.00 per share, volatility of 60%, risk-free
  interest rate of 6.50%, and contractual term of three years. The
       warrant value was recorded to additional paid-in capital and is being
 accreted to the Series B Preferred Stock over 5 1/2 months, the
earliest redemption period.                                   

After consideration of the warrant value and the in-the-money 
       conversion price at the commitment date, the Series B Preferred Stock
   has a "beneficial conversion feature" of $5,213,582 that has been
       recognized as an additional return to the holders through a charge to
        accumulated deficit and an increase to additional paid-in capital. The
         beneficial conversion feature is considered an additional return to the
       preferred stockholders in the determination of net loss applicable to
the common shareholders.                                      

     The conversion price applicable to the Company's Series A Preferred
      Stock issued in May and October 1999 was altered, in accordance with
      its terms, upon the issuance of the Series B Preferred Stock on June
         15, 2000. The Company was required to alter the price used to calculate
        the number of common shares issuable upon the conversion of the Series
        A Preferred Stock to Common Stock. The conversion price was reduced to
         $4.00 from a floor of $7.00 and a ceiling of $11.86. This change caused
      an increase in the value of the beneficial conversion feature in the
       amount of $1,250,000 that has been recognized as an additional return
        to the holders through a charge to accumulated deficit and an increase
  to additional paid-in capital. The beneficial conversion feature
        provided to the Series A preferred stockholders has also been included
     in the determination of net loss applicable to common shareholders.
     Additionally, with respect to the holders of the Series A Preferred
       Stock, the Company was required to increase the number of warrants to
     purchase common stock granted to them from 410,000 to 1,215,650 and
         decrease the warrant exercise price to $4.00 from $11.86. These changes
  caused an increase in the value of the warrants from $1,330,450,
         calculated at the original issuance of the warrants, to $2,340,127. The
     revised value was calculated using an option pricing model with the
         market value of the underlying stock of $4.50, exercise price of $4.00,
   volatility rate of 60%, a risk free interest rate of 6.5% and the
     contractual term of the warrants which is 3 years. This increase in
         warrant value of $1,009,677 has been recognized as an additional return
        to the Series A preferred stockholders through a charge to accumulated
        deficit and an increase to additional paid-in capital. The incremental
        warrant value provided to the Series A preferred stockholders has also
     been included in the determination of net loss applicable to common
shareholders.

December 31, 2000 and 1999

     The conversion price applicable to the Company's Series A Preferred
       Stock issued in May and October 1999 was again altered, in accordance
  with its terms, on August 22, 2000 upon the 180 day reset of the
exercise price of warrants issued with common stock during the
         February, 2000 private placement. The Company was required to alter the
       price used to calculate the number of common shares issuable upon the
 conversion of the Series A Preferred Stock to Common Stock. The
         conversion price was reduced to $3.38 from $4.00. This change caused an
   increase in the value of the beneficial conversion feature in the
       amount of $1,834,320 that has been recognized as an additional return
        to the holders through a charge to accumulated deficit and an increase
  to additional paid-in capital. The beneficial conversion feature
        provided to the Series A preferred stockholders has also been included
     in the determination of net loss applicable to common shareholders.
     Additionally, with respect to the holders of the Series A Preferred
       Stock, the Company was required to increase the number of warrants to
       purchase common stock granted to them from 1,215,650 to 1,438,640 and
        decrease the warrant exercise price to $3.38 from $4.00. These changes
  caused an increase in the value of the warrants from $2,340,127,
    calculated at the original issuance of the warrants and previously
         adjusted by the Series B issuance, to $2,474,461. The revised value was
calculated using an option pricing model with the value of the
        underlying stock of $4.00, exercise price of $3.38, volatility rate of
        60%, a risk free interest rate of 6.5% and the contractual term of the
warrants. This increase in warrant value of $134,334 has been 
recognized as an additional return to the Series A preferred  
         stockholders through a charge to accumulated deficit and an increase to
       additional paid-in capital. The incremental warrant value provided to
   the Series A preferred stockholders has also been included in the
determination of net loss applicable to common shareholders.  

         During April 2000, the Company disbursed $125,000 to satisfy its Series
   A redeemable preferred stock dividend. For all other Series A and
        Series B redeemable convertible preferred stock dividends in 2000, the
    Company elected to issue common stock in payment for the quarterly
       dividends. The Company satisfied these dividend payments by issuing a
  total of 384,631 shares of common stock with an average price of
approximately $1.85 per share.                                

     On October 20, 2000, holders of 1,783 shares of Series B redeemable
         convertible preferred stock, with a face value of $1,783,000, converted
their preferred stock to 445,750 shares of common stock at the
        conversion price of $4.00 per share. In addition, on October 20, 2000,
       the Company elected to pay prorated dividends on the converted shares
         of $17,097, by issuing 6,104 shares of common stock at $2.80 per share.

    In the first quarter of 2001, the holders of Series A and Series B
     redeemable convertible preferred stock agreed to waive the right to
       early redeem their stock and reduce the conversion price of the stock
        to $2.00 in exchange for 46 warrants (per Preferred Share) to purchase
NeoRx common stock.                                           

      Warrants - In connection with the aforementioned Offering, on August
         19, 1997 the Company issued, to Keane Securities Co., Inc., warrants to
         purchase 220,000 shares of the Company's common stock. The warrants are
        exercisable at any time during a four-year period beginning August 19,
 1998 with an exercise price equal to 120% of the initial public
     offering price of the shares ($10.80 per share). As of December 31,
2000 none of the warrants have been exercised.                

       On September 20, 1999, the Company engaged Stonegate Securities, Inc.
      ("Stonegate") to serve as its non-exclusive financial advisor and to
         furnish investment banking services to the Company. The Company paid an
       initial fee of $5,000 on October 1, 1999, and a second fee of $25,000
       on October 26, 1999. Beginning November 15, 1999, a fee of $5,000 per
month began, which amount shall be

        Stonegate warrants to purchase 50,000 shares of common stock at $11.86

        2000 and 1999, respectively, related to the vesting of these warrants.

     2000, and the Company issued 100,000 shares of common stock in full

        The valuation allowances for 2000 and 1999 have been applied to offset
         the deferred tax assets in recognition of the uncertainty that such tax
      benefits will be realized. The net change in valuation allowance for
      the years ended December 31, 2000, 1999, and 1998 was an increase of
       $13,919,265, $4,791,743 and $1,860,525, respectively. At December 31,
 2000, the Company has a net operating loss carryforward for tax
    purposes of approximately $41,141,861 that will begin to expire in
2018.

    capital leases with a book value of $4,529,263, net of accumulated
     depreciation of $818,480. Amortization of assets held under capital
  leases is included with depreciation expense. In April 2001, the
   Company fully paid the remaining lease obligations for all of its
         capital leases in conjunction with the asset sales described in note 2.

    The Company leases office space and certain office equipment under
         operating leases expiring at various dates through 2005. Rental expense
        under such leases for the years ended December 31, 2000, 1999 and 1998
was $64,805, $161,823 and $352,703, respectively.
