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


(1)      The Company and Basis of Presentation

International  Isotopes Inc (the Company) was  incorporated in Texas in November
1995.  The  Company  owns  100% of the  outstanding  common  shares  of its only
subsidiary, International Isotopes Idaho, Inc. (I4).

Nature of Operations -The Company is a manufacturer of calibration and reference
standards   for  nuclear   medicine,   offers  a  selection   of   radioisotopes
(lutetium-177 and iodine-131)  radiochemicals  for various  applications such as
clinical  research,  supplies  cobalt-60  isotope for use in the  Leksell  Gamma
Knife, and provides general  radiological  measurement  capability for processed
gemstones. With the exception of cobalt-60, the Company's normal operating cycle
is considered to be one year.  Due to the time required to produce high specific
activity (HSA)  cobalt-60,  the Company's  operating  cycle for the cobalt-60 is
considered to be three years. All assets expected to be realized in cash or sold
during the normal  operating cycle of business are classified as current assets.
As of March 31, 2004, the Company had 12 full time employees.

Principles of Consolidation - The consolidated  financial statements include the
accounts of the Company and its wholly owned subsidiary  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 three-month  period ended March 31,
2004 are not necessarily  indicative of the results that may be expected for the
year ending December 31, 2004. 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"). 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 three months ended March 31, 2004 and 2003:

(2)      Current Developments and Liquidity

Business  Condition - Since  inception,  the Company  has  suffered  substantial
losses.  During  the  period  ended  March 31,  2004 the  Company  had a loss of
$161,487.  During the period  ended  March 31,  2003,  the Company had a loss of
$258,547.  During the period  ended March 31,  2004,  the  Company's  operations
provided cash in operating activities of $16,055.  During the period ended March
31,  2003,  the  Company's  operations  used  cash in  operating  activities  of
$289,039.   Management  expects  to  generate  sufficient  cash  flows  to  meet
operational needs during 2004 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

As of March 31, 2004 and 2003 there were 101,518,850 and 16,500,000  options and
warrants  outstanding  respectively  and  850  shares  of  Series  B  redeemable
convertible preferred stock that were not included in the computation of diluted
net loss per common share as their effect would have been anti-dilutive, thereby
decreasing the net loss per common share.


(4)      Inventories

Inventories consist of the following at March 31, 2004 and December 31, 2003

                                   March 31, 2004       December 31, 2003

(5)      Acquisition of license rights

During the three months ended March 31, 2004, the Company completed the purchase
of certain assets,  patents and  intellectual  property  related to the fluorine
extraction process. The patents were acquired for $105,000 and the equipment for
$10,000.  The patents and  equipment  will be  amortized/depreciated  over their
estimated  useful lives,  which are 10 years for the patents and 5 years for the
equipment.


                                       7



(6)      Notes Payable

The Company  completed an unsecured note purchase  agreement on January 21, 2004
with certain of the Company's  principal  shareholders  and  Directors  totaling
$650,000.  This is an  unsecured  note  accruing  interest at 6% per year with a
maturity  date of December  31,  2005.  Interest is to be paid on this note on a
semi-annual basis and the Company has the option to prepay the principal balance
at any time  prior  to  maturity.  The  principal  of the  note and any  accrued
interest is convertible into shares of the Company's common stock at any time at
the  option of the  holder  prior to  maturity.  The  conversion  price for this
conversion option was $0.18 per share,  which was the market value of the common
stock.

In January  2004,  the Company  renegotiated  the terms of a line of credit with
it's bank and fixed the terms of the line of credit into a note.  The new terms,
other  than  fixing the line into a note,  extended  the due date of the note to
July 1, 2004 and fixed the interest rate at 7.5% ($733,595  outstanding at March
31, 2004). The Company also negotiated with the same bank an additional $250,000
revolving line of credit with a due date of July 1,2004 ($0 outstanding at March
31, 2004). The Company anticipates renegotiating the revolving line of credit to
extend the due date to December 31, 2004.  Both lines are secured by  inventory,
accounts receivable and equipment.


(7)      Stockholders' Equity and Warrants

During the quarter ended March 31, 2004,  2,061,456  warrants were exercised and
exchanged  for  2,061,456  shares of the  Company's  common  stock.  The Company
received $92,689 for the exercise of these warrants.


(8)      Commitments and Contingencies

Litigation

During February 2004, a lawsuit was filed by Iso-Science Laboratories,  Inc. dba
Isotope  Products  Laboratories in the Superior Court of the State of California
for the County of Los Angeles against the Company,  the Company's  President and
CEO,  a  significant  customer  of the  Company  and  certain  officers  of this
significant customer. In March 2004, the Company filed a response to the lawsuit
in  which  the  Company  denied  all of the  allegations  made in the  suit.  In
addition,  the  Company  has  filed  a  counterclaim  against  Isotope  Products
Laboratories  on the basis that  Isotope  Products  Laboratories  filed the suit
against the Company with the  knowledge  that it has no basis in law or fact and
the  lawsuit  was  calculated  to  interfere  with  the  Company's   contractual
arrangements and prospective business between the Company and its customers. The
Company will continue to vigorously  defend itself in the lawsuit;  however,  an
outcome  favorable to the Company is not determinable at this time.  Should this
lawsuit be settled in a manner  unfavorable  to the Company,  the Company  could
lose its major  line of  revenues  and  could be  required  to make  substantial
payments to the plaintiff.  The Company has a  manufacturing  agreement in place
with this significant  customer,  which indemnifies the Company and its officers
from any loss arising from this suit.  However,  there is no guarantee that this
significant  customer can bear the financial  burden  arising from defending and
possible settlement of this lawsuit.



                                       8


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.
The  revenue  associated  with the sale of HSA  Cobalt is largely  dependent  on
General  Electric,  the Company's  sole  customer of this product.  The gemstone
production  is tied to an exclusive  agreement  with Quali Tech Inc. who in turn
has  a  contracts  with  several  Gemstone   companies,   Medical  flood  source
manufacturing is conducted under an exclusive contract with RadQual, LLC. who in
turn has agreement in place with several  companies  for marketing and sales.  A
loss of any of these  customers  or vendors  could  adversely  affect  operating
results by causing a delay in production or a possible loss of sales.

Contingencies

The Company conducts its operations in Idaho Falls, Idaho.  Although the medical
flood source and gemstone  products appear diverse they share the common link as
being  radioactive  materials.  Therefore,  the  Company is  required to have an
operating license from the Nuclear  Regulatory  Commission ("NRC") and specially
trained  staff to handle  these  materials.  The  Company  has an NRC  operating
license and has,  in fact,  continued  to amend this  license  several  times to
increase  the  amount of  material  permitted  within the  facility.  Additional
processing  capabilities and license  amendments could be implemented that would
permit  processing of other products by the Company but at the present time this
license  does not  restrict  the  volume  of  business  operation  performed  or
projected  to be  performed  in  the  coming  year.  An  irrevocable,  automatic
renewable  letter of credit  against a $151,155  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.


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, 2004 ("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.

RESULTS OF OPERATIONS

Three-month  periods  ended March 31,  2004 and 2003.  The  Company's  loss from
continuing  operations  for the  three-month  period  ended  March 31,  2004 was
$161,487  compared  to a loss of $258,547  from  continuing  operations  for the
comparable  period of 2003. The reduction in loss was attributable to increasing
operational  revenues,  maintaining a consistent  gross profit margin,  and only
having a 12% increase in operating expenses.

Revenues  for the  three-month  period  ended  March 31,  2004 were  $743,325 as
compared  to $359,601  for the same  period in 2003,  an increase of $383,724 or
approximately 106%.  Increased revenues were primarily  attributable to a single
large  cobalt sale that  occurred  during the period,  but the Company  also saw
increases in sales of its nuclear medicine reference and calibration sources and
of its new Iodine -131 product.  Gross profit for the  three-month  period ended
March 31, 2004 was $300,370 as compared to $148,518 for the same period in 2003,
roughly unchanged at 41% of revenues.


                                       9


Operating  expenses increased to $433,044 for the three-month period ended March
31,  2004  compared  to  $388,782  for the same  period of 2003,  an increase of
$44,262 or 11%. Salaries and contract labor expenses for the three-month  period
ended March 31, 2004 was $156,734 as compared to $102,770 for the same period of
2003,  an increase of $53,964 or 52%. The increase was  attributed  to increased
full time staff for operations  and contract labor expense  related to marketing
new products such as  Lutetium-177  and Iodine-131.  General and  administrative
expenses  totaled  $262,743 for the  three-month  period ended March 31, 2004 as
compared to $275,332  for the same period of 2003,  a decrease of $12,589 or 5%.
The  reduction  in G&A  expense  was  related  primarily  to  reduced  corporate
expenditures during the period.

Interest expense for the three-month  period ended March 31, 2004 was $38,262 as
compared  to  $31,918  for the  comparable  period  in 2003.  The  increase  was
attributable to increased long-term debt in the form of a convertible  unsecured
note, and an increase in the interest rate of the Company's bank loan from 7% to
7.5%.

Liquidity and Capital Resources

On March 31, 2004 the Company had cash and cash equivalents of $606,802 compared
to $160,216 at December 31, 2003. For the three months ended March 31, 2004, net
cash provided by operating  activities was $16,055,  investing  activities  used
$261,042, and financing activities provided $691,759.

The Company has financed its operations since inception primarily by bank loans,
product sales, sales of excess equipment,  its initial public offering, sales of
shares of common and  preferred  stock in private  placements  to  investors,  a
rights offering to shareholders, 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: sales of Company products such
as nuclear medicine reference and calibration  standards and radiochemicals such
as  Iodine-131,   contract  manufacturing  and  marketing   relationships;   and
technological and market developments.

Although  there can be no  assurance,  the Company  expects that  revenues  will
continue  to  increase  there can be no  assurance,  the  Company  expects  that
revenues  will  continue  to increase  based upon  trends in sales  performance.
Although  there can be no assurance,  we believe 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
submits  under  the  Securities  Exchange  Act of 1934 is  recorded,  processed,
summarized and reported within the time periods specified in the rules and forms
of the Securities and Exchange Commission.  Based upon their evaluation of those
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

these controls subsequent to the date of the evaluation of those controls by the
chief executive officer and principal financial officer.
