                  INTERNATIONAL ISOTOPES INC. AND SUBSIDIARIES
         Notes to Unaudited Condensed Consolidated Financial Statements


(1)  The Company and Basis of Presentation

International Isotopes Inc. (the Company) was incorporated in Texas in 1995. The
Company is focused primarily on generating  revenues from manufacturing  nuclear
medicine  calibration and reference standards,  processing Topaz Gemstones,  and
the  production  of High  Specific  Activity  (HSA) cobalt from a Department  of
Energy test reactor  (ATR).  As of June 30,  2003,  the Company had 11 full time
employees.

Principles of Consolidation - 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.

Interim   Financial   Information  -  The   accompanying   unaudited   condensed
consolidated   financial  statements  have  been  prepared  in  accordance  with
accounting  principles  generally  accepted in the United  States of America for
interim  financial  information and pursuant to the rules and regulations of the
Securities and Exchange Commission.  Accordingly, they do not include all of the
information and notes required by accounting  principles  generally  accepted in
the United States of America for complete financial  statements.  In the opinion
of management, all adjustments and reclassifications  considered necessary for a
fair  and  comparable  presentation  have  been  included  and  are of a  normal
recurring nature. Operating results for the six-month period ended June 30, 2003
are not necessarily  indicative of the results that may be expected for the year
ending December 31, 2003. The accompanying  financial  statements should be read
in conjunction with the Company's most recent audited financial statements.

Stock-based  Compensation  Plans - The Company accounts for stock options issued
to directors,  officers and employees under Accounting  Principles Board Opinion
No. 25 and  related  interpretations  ("APB  25").  Under  APB 25,  compensation
expense is recognized if an option's  exercise price on the measurement  date is
below the fair value of the Company's common stock. For options that provide for
cashless exercise or that have been modified, the measurement date is considered
the date the options are exercised or expire. Those options are accounted for as
variable options with compensation  adjusted each period based on the difference
between  the market  value of the  common  stock and the  exercise  price of the
options at the end of the period.  The Company accounts for options and warrants
issued to  non-employees  at their fair value in  accordance  with SFAS No. 123,
"Accounting for Stock-Based Compensation" ("SFAS 123").

No  compensation  cost  has  been  recognized  for  its  stock  options  in  the
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  applicable  to  common
shareholders  would have been increased to the pro forma amounts indicated below
for the six months ended June 30, 2003 and 2002:

Recent  Accounting  Pronouncements  - In May 2003 the FASB  issued SFAS No. 150,
"Accounting  for Certain  Financial  Instruments  with  Characteristics  of both
Liabilities and Equity",  which requires that certain  financial  instruments be
presented  as  liabilities  that  were  previously  presented  as  equity  or as
temporary equity.  Such instruments include mandatory  redeemable  preferred and
common  stock,  and certain  options and  warrants.  SFAS 150 is  effective  for
financial  instruments  entered  into or  modified  after  May 31,  2003  and is
generally effective at the beginning of the first interim period beginning after
June 15, 2003.  The Company  adopted SFAS 150 at July 1, 2003 which will require
the Company to reclassify  its 850 shares of  mandatorily  redeemable  preferred
stock with a redemption  value and carrying  amount of $850,000  from  temporary
equity to  long-term  liabilities.  The adoption of this  standard  will have no
effect on net loss.

In November 2002, the FASB issued Financial  Interpretation No. 45, "Guarantor's
Accounting  and  Disclosure  Requirements  for  Guarantees,  Including  Indirect
Guarantees  of  Indebtedness  of  Others."  FIN 45 sets  forth  the  disclosures
required  to be  made by a  guarantor  in its  financial  statements  about  its
obligations under certain  guarantees that it has issued. It also clarifies that
a  guarantor  is required to  recognize,  at the  inception  of a  guarantee,  a
liability  for the fair  value  of the  obligation  undertaken  in  issuing  the
guarantee.  The Company  adopted  the  requirements  FIN 45 in the  accompanying
financial statements.


(2)  Current Developments and Liquidity

Business  Condition - Since  inception,  the Company  has  suffered  substantial
losses.  During  the  period  ended  June  30,  2003 the  Company  had a loss of
$333,578. During the period ended June 30, 2002, the Company had earnings before
preferred  dividends  of $259,348.  During the period  ended June 30, 2003,  the
Company's operations used cash of $264,325 in operating  activities.  During the
period  ended  June 30,  2002,  the  Company's  operations  provided  cash  from
operating activities of $88,472.  Management expects to generate sufficient cash
flows to meet operational  needs during the remainder of 2003 through  financing
and operating capital; however, there is no assurance that these cash flows will
occur.

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

Basic  earnings  (loss) per share  excludes  dilution for  potentially  dilutive
securities  and is computed by dividing  earnings  (loss)  applicable  to common
stockholders by the weighted average number of common shares  outstanding during
the period.

Diluted  earnings  (loss)  per  share,  which is  computed  on the  basis of the
weighted average number of common shares and all potentially dilutive securities
outstanding during the period,  factors in potentially  dilutive  securities and
adding back any convertible  dividend  (except if the effect is  anti-dilutive).
The computation of basic and diluted earnings (loss) per share is as follows:

(5)  Notes Payable

In January 2003,  the Company  entered into an agreement to sell the  Waxahachie
real  estate  for the  assumption  of the  $345,295  debt  associated  with  the
property. As a result of the debt assumption,  the Company remains liable on the
note with Texas State Bank for the  remainder  of the term should the  purchaser
default on this note.

In accordance with Financial  Accounting  Standards Board Interpretation No. 45,
Guarantor's  Accounting and Disclosure  Requirements  for Guarantees,  Including
Indirect  Guarantees of  Indebtedness  of Others,  the Company has  recognized a
$10,000  obligation under the guarantee that consists of the obligation to stand
ready to reassume  the note held at Texas State Bank in the event the  purchaser
defaults on the note.  The  obligation  is based on the cost  necessary  for the
purchaser  to  refinance  the note,  which would  release  the Company  from the
guarantor  position.  Should the  purchaser  default on the note and the Company
reassume the liability, they would also regain the real estate.

During the quarter  ended June 30, 2003,  as part of an  agreement  with certain
shareholders,   the  Company  increased  its  short-term  borrowing  from  these
shareholders to $823,500, the notes bear interest at 5% and are due December 31,
2003.


(6)  Stockholders' Equity and Warrants

During  the  quarter   ended  March  31,  2003,  as  part  of  a  licensing  and
manufacturing settlement agreement,  Bracco Diagnostics returned 8,242 shares of
the Company's common stock. The shares were immediately canceled.

During the six months ended June 30, 2003,  3,027,326 warrants to acquire common
stock with exercise prices ranging from $4.00 to $5.50 expired unexercised

During the quarter ended June 30, 2003, the Company granted 2,000,000 options to
certain  directors to purchase  shares of common stock with an exercise price of
$0.03 per share, which was equal to the closing market price of the common stock
on the date of grant. These options vest through 2006.


(7)  Commitments and Contingencies

Employment Contract

The Company has a five-year  employment  contract with the Company's  president.
The employment agreement extends through February 2007.

Lease Agreement

Effective May 2, 2003, the Company  entered into a new lease  agreement with the
landlord  for a new five year term on the  building.  This new lease  offers the
same  terms and first  rights to  purchase  considerations  that  existed in the
previous lease  agreement but increase  monthly lease rate and purchase price by
an amount proportional to the square footage of the new facility expansion.

Dependence on Third Parties

The production of HSA Cobalt is dependent upon the Department of Energy, and its
prime-operating  contractor, who controls the reactor and laboratory operations.
Actions by the DOE or their prime operating contractor could cause a halt to HSA
cobalt production, which would result in a loss of revenues to the Company and a
loss  of the  value  of all  Work  in  Process  cobalt  material.  The  gemstone
production  is tied to an exclusive  agreement  with Quali Tech Inc. who in turn
has contracts with other clients for gemstone processing. A loss of the contract
with Quali Tech Inc.  would  require  the  Company  to seek  other  clients  for
gemstone  processing.  Nuclear  medicine  calibration  and  reference  standards
manufacturing is conducted under an exclusive contract with RadQual,  LLC, which
in turn has agreements in place with several  companies for marketing and sales.
A loss of the  contract  with  RadQual  LLC would  cause a complete  loss of the
revenues from nuclear medicine calibration and reference standards.

Contingencies

The Company conducts its operations in Idaho Falls, Idaho.  Although the nuclear
medicine  calibration  and  reference  standards  and gemstone  products  appear
diverse  they share the common  link of being  radioactive  materials  requiring
stringent  quality  controls.  Therefore,  the  Company is  required  to have an
operating license from the Nuclear  Regulatory  Commission ("NRC") and specially
trained staff to handle these  products.  An  irrevocable,  automatic  renewable
letter of credit  against a  Certificate  of  Deposit  has been used to  provide
decommissioning  financial  assurance  as  required  by the  Nuclear  Regulatory
Commission for the facility license.


(8)  Subsequent Events

The Company has filed an S-3  Registration  Statement  with the  Securities  and
Exchange  Commission  (SEC) in connection with a rights offering to its existing
shareholders.  The Registration  Statement is anticipated to become effective in
the third  quarter of 2003.  Pursuant  to the  rights  offering  the  Company is
offering for sale  38,229,157  Units (each Unit includes (i) one share of common
stock, (ii) one warrant to purchase another share of common stock for $0.04, and
(iii) one warrant to purchase an additional  share of common stock for $0.05) to
its  shareholders.  Shareholders will receive one Right for each share of common
stock they own.  The Rights  entitle the holders to purchase  one Unit for every
2.5 Rights owned at a  subscription  price of $0.03 per unit.  Shareholders  who
exercise  all of  their  Rights  in full  will  be  entitled  to the  additional
privilege of subscribing for and purchasing,  subject to certain limitations and
subject to allocation,  any Units not acquired by other holders of Rights,  plus
up to an additional 14,500,000 Units if the rights offer is over-subscribed.



ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

Except for  historical  information  contained  herein,  the following  contains
forward-looking  information that is subject to certain risks and uncertainties.
The Company's actual results could differ  materially from those  anticipated in
these forward-looking  statements as a result of certain factors including those
set forth in the "Risk Factors"  section  included in the Company's Form 10-KSB,
filed with the  Securities  Exchange  Commission  (SEC) on March 24, 2003 ("Form
10-KSB").   The  following   discussion  should  be  read  in  conjunction  with
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations" included in the Form 10-KSB.


                                       10


RESULTS OF OPERATIONS

Three and six month  periods ended June 30, 2003 and 2002.

The  Company's  loss from  operations  for the three and six month periods ended
June 30, 2003 were  $74,851 and $333,578  respectively,  as compared to earnings
from continuing  operations of $228,403 and $259,348 for the comparable  periods
of 2002.  The change in earnings was  principally  attributable  to the one time
removal of the $500,000 contingent  liability the Company had in connection with
the sale of the Linac  facility in Denton  Texas.  During the second  quarter of
2002 the Company was released from this contingent liability and recognized this
transaction in other income. Without this one time event, the Company would have
experienced  losses from  operations  of $271,597 and $589,894 for the three and
six months periods  respectively  ended June 30, 2002.  Net earnings  (loss) per
common share for the three and six month  periods ended June 30, 2003 were $0.00
and $0.00  respectively,  as compared to $0.00 and $0.00 for the same periods of
2002. The reason there is no change in this figure is related to rounding.  Both
the 2002 income and 2003 loss are  relatively  small in comparison to the number
of outstanding shares of Company stock.

Revenues for the three and six month  periods  ended June 30, 2003 were $785,262
and $1,144,683 respectively, as compared to $624,084 and $1,150,396 for the same
periods in 2002,  an increase of $161,178 and  decrease of $5,713  respectively.
Gross  profit  for the three  and six  month  periods  ended  June 30,  2003 was
$354,695 and $503,033 respectively, as compared to $252,662 and $578,156 for the
same  periods  in 2002,  an  increase  of  $102,033  and a  decrease  of $75,123
respectively.  The  increase  in revenue  and Gross  profit for the  three-month
period was  attributable  to increased sales of nuclear  medicine  reference and
calibration  standards.  The  decrease  in  revenues  and Gross  profit  for the
six-month period was  attributable to an overall decline in gemstone  production
volumes.

Operating expenses declined to $401,534 and $790,316  respectively for the three
and six-month  periods ended June 30, 2003 compared to $543,419 and $795,907 for
the same periods of 2002. Salaries and contract labor expenses for the three and
six month periods  ended June 30, 2003 were $110,982 and $213,752  respectively,
as compared to $117,765 and $255,080 for the same periods of 2002, a decrease of
$6,783 and $41,328 respectively. General, administrative and consulting expenses
totaled  $290,552 and $576,564  respectively for the three and six month periods
ended June 30, 2003 as compared to $425,654 and $540,827 for the same periods of
2002,  a decrease of  $135,102  and an  increase  of $35,737  respectively.  The
overall decrease in expenses is largely attributable to the Company's efforts to
control costs.

Interest  expense  for the three and six month  period  ended June 30,  2003 was
$50,281 and  $82,199 as  compared  to $44,669  and  $88,611  for the  comparable
periods  in  2002.  The  increase  in  second  quarter   interest   expense  was
attributable  to the short term loans made to the Company by several  Principals
and Directors during the period.

Liquidity and Capital Resources

On June 30, 2003 the Company had cash and cash equivalents of $824,518  compared
to  $441,904 at  December  31,  2002.  For the six months  ended June 30,  2003,
operating  activities used cash of $264,325,  investing activities provided cash
of $159,322  and  financing  activities  provided  cash of  $487,617.  Cash from
financing activities consisted primarily of short-term notes provided by several
principals and directors.


                                       11


The Company has financed its operations since inception primarily by bank loans,
sales of  accelerator  components  and  excess  equipment,  its  initial  public
offering, sales of shares of common and preferred stock in private placements to
investors, and loans from stockholders and directors.

The Company's future liquidity and capital funding  requirements  will depend on
numerous factors, including, but not limited to: sale of remaining Texas assets,
contract manufacturing and marketing relationships; and technological and market
developments.  It is  anticipated  that  the  rights  offering  will  convert  a
significant  amount of the Company's current  liabilities to equity and generate
cash to be used for the acquisition of assets. This should improve the Company's
financial strength, debt ratio, and attractiveness to lending institutions.

Although  there can be no  assurance,  the Company  expects that  revenues  will
continue to increase. These increased revenues will provide sufficient funds for
operations and capital expenditures.


ITEM 3.  CONTROLS AND PROCEDURES

(a)  The  Company  maintains  controls  and  procedures  designed to ensure that
information  required to be disclosed  in the reports that the Company  files or

controls  and  procedures  performed  within 90 days of the filing  date of this
report,  the chief executive officer and the principal  financial officer of the
Company  concluded that the Company's  disclosure  controls and procedures  were
adequate.

(b)  Changes in internal  controls.  The Company made no significant  changes in
its internal controls or in other factors that could significantly  affect these
controls subsequent to the date of the evaluation of those controls by the chief
executive officer and principal financial officer.
