NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements of IGEN
International, Inc. (the Company) have been prepared in accordance with
accounting principles generally accepted in the United States of America for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation S-X. Accordingly, certain information and footnote disclosures
normally included in financial statements have been condensed or omitted. In the
opinion of the Company's management, the financial statements reflect all
adjustments necessary to present fairly the results of operations for the three
and six month periods ended September 30, 2003 and 2002, the Company's financial
position at September 30, 2003 and the cash flows for the six month periods
ended September 30, 2003 and 2002.

The results of operations for the interim periods are not necessarily indicative
of the results for any future interim period or for the entire year. These
financial statements should be read together with the audited financial
statements and notes for the year ended March 31, 2003 contained in the
Company's Annual Report on Form 10-K for the year ended March 31, 2003 filed
with the Securities and Exchange Commission (SEC).

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates. Certain amounts from the prior years have been reclassified to
conform to the current year presentation.

The consolidated  financial  statements  include the accounts of the Company and
its  wholly-owned   subsidiaries,   IGEN  Europe,   Inc.,  BioVeris  Corporation
(BioVeris)  and  IGEN   International,   K.K.  All   significant   inter-company
transactions and balances have been eliminated.

2. ROCHE TRANSACTION

On July 24, 2003, the Company and Roche Holding Ltd.  (Roche) jointly  announced
that they had reached definitive agreements pursuant to which Roche will acquire
the Company and the Company will simultaneously distribute the common stock of a
new company,  BioVeris,  to its stockholders.  The transaction will occur in the
following steps:

     o    The Company will restructure its operations so that BioVeris,  a newly
          formed  wholly-owned  subsidiary  of  the  Company,  will  assume  the
          Company's  biodefense,  life sciences and industrial  product lines as
          well as the Company's  opportunities  in the clinical  diagnostics and
          healthcare fields, and will own the Company's  intellectual  property,
          the Company's equity interest in Meso Scale  Diagnostics,  LLC. (MSD),
          cash and  certain  other  rights and  licenses  currently  held by the
          Company; and

     o    A  wholly-owned  subsidiary  of  Roche  will  merge  with and into the
          Company,  as a result of which the Company will become a  wholly-owned
          subsidiary  of  Roche  and  BioVeris   will  become  an   independent,
          publicly-traded   company   owned  by  the   Company's   stockholders.
          Simultaneously  with the  completion  of the merger,  certain  ongoing
          commercial agreements between BioVeris and certain affiliates of Roche
          will become effective.




                                       4




The obligations of the parties to complete the merger are subject to certain
conditions, including the adoption of the merger agreement by the Company's
stockholders, the receipt by the Company of a solvency opinion substantially to
the effect that BioVeris will not be insolvent after giving effect to the merger
and related transactions and the execution and delivery of the ongoing
commercial agreements, and that Roche will have loaned the Company up to $214
million, such loan remaining the obligation of the Company following the
completion of the merger. All cash on hand at the Company will be transferred to
BioVeris as part of the restructuring.

Upon completion of the merger, each outstanding share of the Company's common
stock will be converted into the right to receive $47.25 in cash, without
interest, and one share of BioVeris common stock. In addition, upon completion
of the merger, all outstanding options granted under the Company's stock option
plans, including unvested options, will be canceled and the holder of any such
options will have the right to receive for each share covered by such option
cash from Roche equal to the excess of $47.25 over the exercise price of such
option (without interest) and one share of BioVeris common stock.

Effective, simultaneously with the completion of the merger, Roche will hold a
new worldwide, non-exclusive, fully-paid, royalty-free, perpetual license under
patents and technology that relate to detection methods and systems which employ
electrochemiluminescence (ECL) technology, but specifically excluding technology
related to gene amplification or compounds composed of or capable of binding
with nucleotides. The license may be used only in a specific field, generally
described as the human in vitro diagnostics field, to develop, make, reproduce,
modify, use, sell and otherwise commercially exploit specified products. The
Company's rights, as licensor under the license agreement, will be transferred
to BioVeris as part of the restructuring.

As part of the merger and related transactions, the Company and Roche have
entered into an ongoing litigation agreement providing that all litigation
between the parties be suspended pending the completion of the merger (see Note
8). As partial consideration for the ongoing litigation agreement and for
Roche's use of ECL technology pending completion of the merger, Roche is
obligated to pay the Company a fixed monthly fee of $5.0 million which commenced
in July 2003 and will be payable until the completion of the merger. Effective
July 1, 2003, there were no further royalties owed to the Company under the
Roche license agreement. In addition, in July 2003, Roche paid the Company $18.6
million in cash for damages arising out of the Maryland contract action. See
Note 3 for a description of the presentation of Roche revenue in the
accompanying consolidated statements of operations.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents - Cash and cash equivalents include cash in banks,
money market funds, securities of the U.S. Treasury, and certificates of deposit
with original maturities of three months or less.

Short-Term Investments - Short-term investments consist primarily of corporate
debt securities that are classified as "available for sale." These "available
for sale" securities, which are all due within one year, are accounted for at
their fair market value and unrealized gains and losses on these securities, if
any, are reported in accumulated other comprehensive loss in stockholders'
equity. As of September 30, 2003, the Company had unrealized losses on
"available for sale" securities of approximately $179,000.

                                       5



The Company uses the specific identification method in computing realized gains
and losses on the sale of investments, which are included in results of
operations as generated. Any realized gains or losses were not material as of
and for the periods ended September 30, 2003 and 2002.

Concentration of Credit Risk - The Company has invested its excess cash
generally in securities of the U.S. Treasury, money market funds, certificates
of deposit and corporate bonds. The Company invests its excess cash in
accordance with a policy objective that seeks to ensure both liquidity and
safety of principal. The policy limits investments to certain types of
instruments issued by institutions with strong investment grade credit ratings
and places restrictions on their terms and concentrations by type and issuer.
The Company has not experienced any losses on its investments due to credit
risk.

Restricted Cash - The Company has a debt service reserve of approximately $1.7
million that is restricted in use and held in trust as collateral (see Note 5).

Allowance for Doubtful Accounts - The Company maintains reserves on customer
accounts where estimated losses may result from the inability of its customers
to make required payments. These reserves are determined based on a number of
factors, including the current financial condition of specific customers, the
age of accounts receivable balances and historical loss rates.

Inventory - Inventory is recorded at the lower of cost or market using the
first-in, first-out method and consists of the following (in thousands):

Equipment and Leasehold Improvements - Equipment and leasehold improvements are
carried at cost, less accumulated depreciation and amortization. Depreciation on
equipment is computed over the estimated useful lives of the assets, generally
three to five years, using straight-line or accelerated methods. Leasehold
improvements are amortized on a straight-line basis over the life of the lease.

Capitalized Software Costs - Software development costs incurred after
technological feasibility is established are capitalized in accordance with
Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for the
Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed." To date,
software development has been substantially completed concurrently with the
establishment of technological feasibility, and accordingly, no costs have been
capitalized to date.

Evaluation of Long-Lived Assets - The Company evaluates the potential impairment
of long-lived assets whenever events or changes in circumstances indicate that
the carrying amount of an asset may not be fully recoverable. In evaluating the
recoverability of an asset, management's policy is to compare the carrying
amount of an asset with the projected undiscounted future cash flow. Management
believes no impairment of these assets exists as of September 30, 2003.


                                       6




Warranty Reserve - The Company warrants its products against defects in
materials and workmanship for one year after sale and records estimated future
warranty costs at the time revenue is recognized. A reserve for future warranty
claims is recorded based upon management's review of historical claims,
supplemented by expectations of future costs. The Company also offers extended
warranty arrangements to customers, for which related costs are recorded as
incurred.

Warranty reserve activity during the six months ended September 30, 2003 is as

Revenue Recognition - The Company derives revenue principally from three
sources: product sales, royalty income and contract fees.

Product sales revenue is recognized when persuasive evidence of an arrangement
exists, the price to the buyer is fixed and determinable, collectibility is
reasonably assured and the product is shipped to the customer thereby
transferring title and risk of loss. Rental revenue associated with instruments
that are leased is recognized ratably over the life of the lease agreements.
Revenue associated with extended warranty arrangements is recognized over the
term of the extended warranty contract.

Royalty income is recorded when earned, based on information provided by
licensees.

Revenue from services performed under contracts is recognized over the term of
the underlying customer contract or at the end of the contract, when obligations
under the contract have been satisfied. For services performed on a time and
material basis, revenue is recognized upon performance. Amounts received in
advance of performance under contracts are recorded as deferred revenue until
earned.

                                       7


Roche Revenue - Roche revenue is comprised of revenues earned by the Company
from Roche, including:

     o    A  fixed  monthly  fee of $5.0  million  for  the  use of  ORIGEN  (R)
          technology.  The fixed  monthly fee commenced in July 2003 and will be
          payable to the Company until the completion of the merger,

     o    Royalties  paid under the 1992 license  agreement  between the Company
          and Roche for the period  through June 30,  2003,  which are no longer
          required  as a result of a new  agreement  between  the  parties  that
          provides for fixed monthly payments, as described above,

     o    Fees earned in  connection  with the  Company's  performance  under an
          assay development contract with Roche.

Research and Development - Research and development costs are expensed as
incurred.

Foreign Currency - Gains and losses from foreign currency transactions, such as
those resulting from the settlement of foreign receivables or payables, are
included in the results of operations as incurred. These amounts were not
material during the six months ended September 30, 2003 and 2002.

Deferred Income Taxes - Deferred income tax assets and liabilities are computed
annually for differences between the financial statement and tax bases of assets
and liabilities that will result in taxable or deductible amounts in the future
based on enacted tax laws and rates applicable to the periods in which the
differences are expected to affect taxable income. A valuation allowance is
established when necessary to reduce deferred tax assets to the amount expected
to be realized.

Stock-Based Compensation - The Company has elected to continue to follow the
recognition and measurement principles of Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees", and related Interpretations
in accounting for its employee stock options. Accordingly, no stock-based
employee compensation cost is reflected in net income (loss) for the three and
six months ended September 30, 2003 and 2002, as all options granted under those
plans had an exercise price equal to the market value of a share of the
underlying common stock on the date of the grant.

The following table illustrates the effect on net income (loss) and net income
(loss) per share as if the Company had applied the fair value recognition
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" as amended
by SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and
Disclosure - An Amendment of SFAS No. 123" to stock-based employee compensation

The pro forma net income (loss) and net income (loss) per share disclosed above
is not likely to be representative of the effects on net income (loss) and net
income (loss) per share on a pro forma basis in future years, as future years
may include additional grants of options for the Company's stock and continued

Company's common stock will become fully vested and will be canceled.

No stock options were granted during the three months ended September 30, 2003.
For all other periods presented, the fair value of options for the Company's

Based on this calculation, the weighted average fair value of options granted
during the three months ended September 30, 2002 and the six months ended
September 30, 2003 and 2002 was $16.43, $21.09 and $21.37, respectively.

Income (Loss) Per Share - The Company uses SFAS No. 128, "Earnings per Share",
for the calculation of basic and diluted earnings per share. For periods when
the Company recorded a loss, the loss has been adjusted by dividends accumulated
on the Company's Series B Convertible Preferred Stock (Series B) for all periods
during which the Series B was outstanding.

For the three and six months ended September 30, 2002, the Company incurred a
net loss; therefore the net loss per common share does not reflect the potential
dilution that could occur to common shares related to outstanding stock options,
warrants, convertible preferred stock and convertible debentures. The weighted
average number of common shares outstanding together with potentially dilutive
shares was 25,570,451 and 25,323,420 for the three and six months ended
September 30, 2002, respectively.

New Accounting Standards - In January 2003, the Financial Accounting Standards
Board (FASB) issued Interpretation No. 46, "Consolidation of Variable Interest
Entities" (FIN 46). FIN 46 provides guidance on variable interest entities and
the framework through which an enterprise assesses consolidation of a variable
interest entity. FIN 46 was effective immediately for variable interest entities
created or acquired after January 31, 2003. In October 2003, the FASB issued
Staff Position FIN 46-6, which extended the effective date of FIN 46 for
variable interest entities created or acquired before February 1, 2003 to the
first interim or annual period ending after December 15, 2003. The Company has
adopted FIN 46 and has determined that MSD qualifies as a variable interest
entity under FIN 46 because substantially all of MSD's funding is being provided
by the Company and the Company's voting rights are not proportional to its
obligation to absorb a majority of the potential future losses of MSD.
Accordingly, beginning October 1, 2003, the Company will consolidate the
financial results of MSD. Consolidation accounting will require certain
reclassifications within the Company's consolidated financial statements but is
not expected to materially affect its financial position or net loss, as the
Company has recorded approximately 100% of MSD's losses.

                                       9



In April 2003, the FASB issued SFAS No. 149, "Amendment of SFAS No. 133 on
Derivative Instruments and Hedging Activities" (SFAS 149). SFAS 149 amends and
clarifies accounting for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities under SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities". The
amendments set forth in SFAS 149 improve financial reporting by requiring that
contracts with comparable characteristics be accounted similarly. SFAS 149 is
effective for contracts entered into or modified after June 30, 2003 and for
hedging relationships designated after June 30, 2003. The implementation of SFAS
149 did not have a material effect on the Company's financial position or
results of operations.

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity" (SFAS 150).
SFAS 150 establishes standards regarding the classification and measurement of
certain financial instruments with characteristics of both liabilities and
equity. SFAS 150 is effective for financial instruments entered into or modified
after May 31, 2003, and otherwise is effective at the beginning of the first
interim period beginning after June 15, 2003. The implementation of SFAS 150 did
not have a material effect on the Company's financial position or result of
operations.

4. MESO SCALE DIAGNOSTICS JOINT VENTURE

MSD is a joint venture formed by MST and the Company in 1995. MSD was formed for
the development, manufacture, marketing and sale of products utilizing a
combination of MST's multi-array technology together with the Company's
technology. MST is a company established and wholly-owned by Jacob Wohlstadter,
a son of the Company's chief executive officer. In August 2001, the Company
amended the MSD joint venture agreement, the MSD limited liability company
agreement and certain license and other agreements with MSD and MST to continue
the MSD joint venture and entered into various related agreements (the MSD
agreements). An independent committee of the Company's board of directors, with
the advice of independent advisors and counsel, negotiated and approved the MSD
agreements.

As part of the restructuring, the Company will transfer its equity interest in
MSD to BioVeris and will assign the MSD agreements to BioVeris. The Joint
Venture Oversight Committee (JVOC), a committee of the Company's board of
directors, consisting of independent directors, with the advice of independent
counsel, negotiated and approved certain agreements with MSD made in connection
with the proposed transaction between IGEN and Roche, which amendments include
BioVeris's obligation to make a final capital contribution of $37.5 million to
MSD following the completion of the merger.

Under the MSD agreements, the Company's funding commitment was based on an
annual budget of MSD approved by the JVOC. The JVOC approved funding for MSD by
the Company for the period from January 1, 2003 to November 30, 2003 in an
amount of $20.6 million, subject to a permitted variance of 15%. As of September
30, 2003, the Company's remaining funding commitment to MSD was $5.4 million.
This remaining funding commitment may be satisfied in part through in-kind
contributions of scientific and administrative personnel and shared facilities.
For the six months ended September 30, 2003 and 2002, the Company made total
contributions to MSD of $15.3 million and $10.8 million, respectively, including
$3.7 million in the current year which related to permitted budget variances
from prior years. In addition, in the event the proposed transaction between
IGEN and Roche is not completed prior to December 1, 2003, the Company has
agreed to provide continued interim funding to MSD, payable monthly on the first
day of each month commencing on December 1, 2003 until the earlier to occur of
completion of the merger or termination of the merger agreement.

                                       10



The monthly funding will equal approximately $1.7 million, which is 1/12th of
the Company's aggregate funding commitment under the MSD budget for 2003
approved by the JVOC. Any interim funding will reduce the amount of BioVeris's
final capital contribution following the completion of the merger.

The Company holds a 31% voting equity interest in MSD and is entitled to a
preferred return on $72.2 million of the funds previously invested by it in MSD
through September 30, 2003 and on all additional funds invested by it
thereafter. This preferred return would be payable out of a portion of both
future profits and certain third-party financings of MSD, generally before any
payments are made to other equity holders. Although MST owns the remaining 69%
voting equity interest in MSD, the Company generally has the right to approve
significant MSD governance matters. In exercising this right, an independent
committee of the Company's board of directors must consider the Company's
interests and the interests of the Company's stockholders while also taking into
consideration the interests of MSD.

Under the terms of one of the MSD agreements, the Company granted to MSD a
worldwide, perpetual, exclusive license (with certain exceptions) to the
Company's technology, including ECL technology, for use in MSD's research
program, defined in the MSD agreements. If the Company ceases to be a member of
MSD, it will become entitled to receive royalty payments from MSD on all
products developed and sold by MSD using the Company's patents. MST holds a
worldwide, perpetual, non-exclusive sublicense from MSD for certain
non-diagnostic applications of the Company's technology. The Company is entitled
to receive royalty payments from MST on any products developed and sold by MST
using the Company's patents.

During the term of the MSD joint venture agreement, MSD is the Company's and
MST's exclusive means of conducting the MSD research program, and the Company is
obligated to refrain from developing or commercializing any products, processes
or services that are related to the MSD research program in the diagnostic
field, as defined for purposes of the MSD agreements, or to MSD's research
technologies as described in the MSD agreements, subject to certain exceptions.
After the expiration or termination of the MSD joint venture agreement, the
Company may not use the improvements granted to it by MSD if doing so would
compete with MSD in the diagnostic field.

As part of the merger agreement and related transactions,  the Company, BioVeris
and MSD agreed that the MSD joint venture  agreement will expire on the later of
(1) November 30, 2003,  or (2) the earlier of (a) the date of the  completion of
the merger or (b) the  termination  of the merger  agreement.  In  addition,  in
accordance with the MSD agreements,  MST and MSD have the right to terminate the
MSD joint venture agreement prior to its expiration under certain circumstances,
including  (1) breach of the  Company's  obligations,  including  the  Company's
funding  obligations to MSD, (2) MSD's  termination  of Mr. Jacob  Wohlstadter's
employment (other than for cause or disability), (3) if Mr. Jacob Wohlstadter is
entitled to terminate  his  employment  agreement for good reason (as defined in
his  employment  agreement)  or (4) upon a change in control of the Company,  as
defined. MSD, MST and Mr. Jacob Wohlstadter have each agreed that the merger and
related transactions will not constitute a change in control for purposes of the
MSD agreements and the Jacob Wohlstadter employment agreement.


                                       11



Upon the  expiration of the MSD joint  venture as a result of the  completion of
the  merger  or  termination  of  the  merger  agreement  or the  expiration  or
termination of the MSD joint venture agreement for any other reason, MSD and MST
will have the right to purchase the Company's or BioVeris's, as the case may be,
entire  interest in MSD for a purchase  price equal to fair market  value (to be
determined in accordance with the provisions and procedures set forth in the MSD
agreements, which shall include a determination by appraisers if the parties are
unable to agree on fair market value) minus a discount  factor varying from 7.5%
to 15%.  If MSD or MST  exercises  this  right,  it will be  required to pay the
Company  or  BioVeris,  as the case may be, the  purchase  price,  plus  simple,
cumulated but not compounded  interest at the fixed annual rate of 0.5% over the
prime  rate in  effect  on the date MSD or MST,  as the case may be,  elects  to
purchase the interests.  The purchase price is payable over time in installments
equal to the sum of 5% of MSD net sales,  as determined  in accordance  with the
MSD  agreements,  and 20% of the net  proceeds  realized by MSD from the sale of
debt or equity  securities in any  third-party  financing  after the date of the
sale of the  Company's or  BioVeris's,  as the case may be,  interest in MSD. As
security for the payment  obligation,  BioVeris will hold a security interest in
the interests in MSD that are being  purchased.  MST or MSD, as the case may be,
may  repay  all or any  part of the  outstanding  purchase  price  plus  accrued
interest  at any time and  from  time to time  without  penalty.  Following  the
expiration  of the MSD joint venture  agreement,  many of the licenses and other
arrangements   with  MSD  and  MST  assigned  to  the  Company   will   continue
indefinitely.

Following the expiration or termination of the MSD joint venture agreement,  MSD
will be entitled to continue to lease certain  facilities and related  equipment
from  the  Company  or  BioVeris,  as the  case  may be,  (including  laboratory
facilities  located in the  Company's  corporate  headquarters)  pursuant to the
terms of existing  sublease  agreements with MSD. The term of each sublease will
expire one day prior to the expiration of the prime lease. Following termination
or  expiration  of the MSD  joint  venture  agreement,  MSD or the  Company  (or
BioVeris  as the  case  may be)  may  unilaterally  terminate  any or all of the
subleases by providing at least 18 months' prior written notice of  termination.
If the Company or BioVeris,  as the case may be,  elects to terminate a sublease
for a  facility,  MSD may elect to remain  in that  facility  after the 18 month
period  expires for any period of time  selected by MSD, but not longer than one
day prior to the expiration of the prime lease  (including any extensions of the
prime lease). The Company or BioVeris,  as the case may be, has an obligation to
MSD to exercise all available  extension rights under its lease agreements which
are subject to sublease  arrangements with MSD. After a notice of termination of
a sublease has been sent,  MSD will be required to pay its pro rata share of all
rent and other expenses incurred by the Company or BioVeris, as the case may be,
under the prime lease.  MSD and MST may elect, if either  exercises its right to
purchase the Company's or BioVeris's,  as the case may be,  interests in MSD, to
have its rent and expense  payment  obligations for the 18 month period included
in the purchase price of those interests in MSD.

MSD has an employment agreement with Mr. Jacob Wohlstadter, its president and
chief executive officer, the current term of which runs through November 30,
2004 and provides for a salary of $250,000 for the year ending December 31,
2003. In addition, Mr. Jacob Wohlstadter is also eligible to receive, at the
discretion of the JVOC, an annual cash bonus in an amount not to exceed 20% of
his annual salary. During year ended December 31, 2003, Mr. Jacob Wohlstadter is
expected to receive $250,000 from his employment at MSD. If MSD terminates the
employment agreement without cause, or Mr. Jacob Wohlstadter terminates the
employment agreement for good reason (which includes a "change in control" of
the Company, as defined), Mr. Jacob Wohlstadter will be entitled to receive, in
addition to salary and pro rata bonus and adjustments earned through the 60th
day following the notice of termination, an amount equal to from 3 to 12 times
(depending on the reason for the termination) the monthly pro rata salary, bonus
and adjustments in effect at the time of the termination. Under the employment
agreement Mr. Jacob Wohlstadter is also entitled to receive a gross-up for any
"parachute" excise tax imposed on payments made or benefits provided pursuant to
the agreement. In addition, upon such a termination prior to the expiration of
the MSD joint venture agreement, MSD and MST shall have a joint right to
purchase the Company's interest in MSD on terms described above.

The Company will be responsible for all amounts payable, costs incurred and
other obligations under the employment agreement prior to the termination of the
Company's funding obligation to MSD following the completion of the merger,
which generally are expected to be paid out of the Company's funding commitment
to MSD. MSD, MST and Jacob Wohlstadter have each agreed that the merger and
related transactions will not constitute a change in control for purposes of the
MSD agreements and the employment agreement.

The Company will also indemnify Mr. Jacob Wohlstadter against certain
liabilities, including liability from the MSD joint venture relating to the
period of the Company's involvement with MSD. In addition, the Company will be
obligated under the MSD agreements to indemnify each board member or officer of
MSD with respect to any action taken by such person prior to the Company ceasing
to be a member of MSD by reason of the fact that such person is or was a board
member or an officer of MSD.

                                       12



Since inception of the MSD joint venture, the equity method has been utilized to
account for the investment. In conjunction with entering into the MSD agreements
and taking into account the progress made by MSD in the development of its
products, it was determined that future contributions to MSD would be made based
on the future investment benefit to be obtained by it. Therefore, the Company
share of MSD losses since July 1, 2001, has been recorded as Equity in Loss of
Affiliate. During the three months ended September 30, 2003 and 2002 and the six
months ended September 30, 2003 and 2002, operating costs allocated to MSD by
the Company in connection with shared personnel and facilities totaled $1.9
million, $3.2 million, $4.1 million and $5.8 million, respectively. These
allocated operating costs reduced certain operating costs and expenses and
increased Equity in Loss of Affiliate in the accompanying consolidated
statements of operations. The Company's investment in affiliate totaled $14.8
million at September 30, 2003. See Note 3 for discussion of consolidation
accounting of the MSD investment as of October 1, 2003.

5. NOTE PAYABLE

In March 1999, the Company entered into a debt financing with John Hancock
Mutual Life Insurance Company under a Note Purchase Agreement (Notes) from which
the Company received $30 million. The 8.5% Senior Secured Notes mature in March
2006 with principal and interest payments of $1.7 million due quarterly through
March 2006. Collateral for the debt is represented by royalty payments and
rights of the Company to receive monies due pursuant to the Company's license
agreement with Roche. Additional collateral is represented by restricted cash
(see Note 3), which had a balance of $1.7 million at September 30, 2003.
Covenants within the Note include compliance with annual and quarterly Royalty
Payment Coverage Ratios, which are tied to royalty payments and debt service.

On July 9, 2003, the Appellate  Court affirmed the Company's  right to terminate
the  Roche  license  agreement  and the  Company  immediately  issued  a  notice
confirming  termination of that agreement.  Termination of the Roche license led
to, among other things,  termination of the Company's  right to receive  royalty
payments  from Roche on its net sales of  products  based on the  Company's  ECL
technology.  As part of the merger and related transactions,  Roche is obligated
to pay the  Company a monthly  fee of $5.0  million  for the period from July 1,
2003 through the closing of the merger for Roche's use of ECL technology pending
completion of the merger (see Notes 2 and 3).  Termination  of the Roche license
agreement  is an event of default  under the Notes.  Pursuant  to the  agreement
under which the Notes were  issued,  if an event of default has  occurred and is
continuing, the holder of the Notes may declare all of the Notes immediately due
and payable. If accelerated, the Company would be obligated to pay the remaining
principal amount due plus accrued interest and a make-whole  amount.  The holder
of the  Notes has  indicated  that it is not  planning  to  declare  an event of
default or  accelerate  payment of the Notes pending  the closing of the Roche
Transaction.  As a result of the potential  acceleration,  the outstanding Notes
balance  of  $15.4  million,  as  well  as  the  $1.7  million  restricted  cash
collateral,  has been  reflected  as a  current  liability  and  current  asset,
respectively,  in the accompanying  condensed  consolidated  balance sheet as of
September 30, 2003.


6. SUBORDINATED CONVERTIBLE DEBENTURES

In January 2000, the Company completed a placement of $35.0 million principal
amount of Subordinated Convertible Debentures. The 5% debentures, if not
converted, were to mature in January 2005 with semi-annual interest payments to
be made in cash or an equivalent value of common stock.

                                       13



In September 2003, all debentures were converted by the holders and the Company
issued 1,129,032 shares of common stock, representing a fixed conversion price
of $31 per share. Upon conversion, the face value of the debentures totaling
$35.0 million was reclassified from liabilities to stockholders' equity and the
remaining unamortized discount of approximately $2.4 million was recorded as a
non-recurring, non-cash interest expense. In addition, upon conversion, the
Company paid $400,000 of accrued interest on the debentures.

As part of this financing, the Company also issued detachable warrants to
purchase 282,258 shares of the Company's common stock with an exercise price of
$31 per share. Using the Black-Scholes option pricing model and the relative
fair value of the warrants and the debentures at the time of issuance, these
warrants were valued at approximately $7.0 million. As of September 30, 2003,
all warrants remain outstanding.

Following the completion of the merger, the holder of outstanding warrants of
the Company will, upon exercise, be entitled to receive from BioVeris the number
of shares of BioVeris common stock as if such holder had exercised the warrants
for the shares of the Company's common stock issuable upon exercise of the
warrants immediately prior to the completion of the merger; and receive from
Roche or the Company the amount of cash as if such holder had exercised the
warrants for the shares of the Company's common stock issuable upon exercise of
the warrants immediately prior to the completion of the merger.

7. STOCKHOLDERS' EQUITY

In connection with the exercise of stock in July 2000, the Company granted a
loan to the Company's Chief Executive Officer in the principal amount of $2.1
million, maturing in July 2007. The loan is a 6.62% simple interest (paid
annually), full recourse loan against all assets of the borrower, collateralized
by the pledge of 100,000 shares of the Company's common stock owned by the
borrower. Upon completion of the proposed merger with Roche, this loan will
become immediately due.

8.       LITIGATION

Roche

In 1997,  the  Company  filed a  lawsuit,  which  is  referred  to as the  Roche
litigation,  against  Roche in the  U.S.  District  Court  for the  District  of
Maryland (District Court). The lawsuit arose out of the Roche license agreement,
under which the Company licensed to Roche certain rights to develop, manufacture
and sell diagnostic  products based on the Company's ORIGEN  technology.  In the
Roche litigation,  the Company alleged, among other things, that Roche failed to
perform  certain  material  obligations  under the Roche  license  agreement and
engaged in unfair competition against the Company.

The jury trial in this litigation was completed in January 2002, and the jury
rendered a verdict that Roche had materially breached the license agreement, had
violated its duty to the Company of good faith and fair dealing, and had engaged
in unfair competition against the Company. In February 2002, the District Court
issued a final order of judgment that confirmed the jury's decisions to award
$105 million in compensatory damages and $400 million in punitive damages,
entitled the Company to terminate the Roche license agreement, and directed
Roche to grant to the Company for use in its retained fields a license to
certain improvements.


                                       14



Roche was also ordered, at its sole cost and expense, to deliver such
improvements to the Company and to provide all other information and materials
required or necessary to enable the Company to commercialize these improvements.
Improvements, as defined in the final order of judgment, include Roche's Elecsys
1010, 2010 and E170 lines of clinical diagnostic immunoassay analyzers, the
tests developed for use on those systems, and certain aspects of Roche's nucleic
acid amplification technology called PCR. The final order of judgment also
barred Roche from marketing, selling, placing or distributing outside of its
licensed field any products, including its Elecsys diagnostics product line,
that are based on the Company's ORIGEN technology. In April 2002, the District
Court denied Roche's motions challenging the judgment.

Roche appealed certain aspects of the final order of judgment to the U.S. Court
of Appeals for the Fourth Circuit (Appellate Court). During the appeal process
Roche was obligated to continue to comply with the terms of the Roche license
agreement, including its obligation to continue to pay the Company royalties on
Roche's sales of royalty bearing products and to share and deliver improvements.
Roche's obligation to pay the $505 million of monetary damages awarded to the
Company was suspended until completion of the appeal process. On July 9, 2003,
the Appellate Court issued its ruling on the Roche appeal. The ruling eliminated
damages of $486.8 million previously awarded to the Company by the jury, while
affirming $18.6 million in compensatory damages, the Company's right to
terminate the license agreement between the companies, and the Company's right
to certain improvements in certain fields developed by Roche under the license
agreement.

As part of the merger and related transactions, the Company and Roche have
entered into an ongoing litigation agreement providing that all litigation
between the parties be suspended pending the completion of the merger. The
Company has suspended its patent infringement actions against Roche in Maryland
and Germany pending completion of the merger, with the right to resume the
actions should the merger not be completed. Roche has withdrawn its petition for
rehearing before the Appellate Court and both companies have agreed not to file
any further appeals of the opinion issued by that court.

Other Proceedings

The Company is involved, from time to time, in various other routine legal
proceedings arising out of the normal and ordinary operation of its business,
which it does not anticipate will have a material adverse impact on its
business, financial condition, results of operations or cash flows.

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

This Management's Discussion and Analysis of Financial Condition and Results of
Operations as of September 30, 2003 and for the three and six month periods
ended September 30, 2003 and 2002 should be read in conjunction with the
Management's Discussion and Analysis of Financial Condition and Results of

Roche Transaction

On July 24, 2003, IGEN and Roche jointly announced that they had reached
definitive agreements pursuant to which Roche will acquire us and we will
simultaneously distribute the common stock of a new company, BioVeris, to our
stockholders. The transaction will occur in the following steps:

                                       17




     o    We will  restructure  our operations so that BioVeris,  a newly formed
          wholly-owned  subsidiary  of IGEN,  will assume our  biodefense,  life
          sciences and industrial  product lines as well as our opportunities in
          the  clinical  diagnostics  and  healthcare  fields,  and will own our
          intellectual  property, our equity interest in Meso Scale Diagnostics,
          LLC. (MSD), cash and certain other rights and licenses  currently held
          by us; and

     o    A  wholly-owned  subsidiary of Roche will merge with and into us, as a
          result of which we will become a wholly-owned  subsidiary of Roche and
          BioVeris will become an independent,  publicly-traded company owned by
          our  stockholders.  Simultaneously  with the completion of the merger,
          certain ongoing  commercial  agreements  between  BioVeris and certain
          affiliates of Roche will become effective.

The obligations of the parties to complete the merger are subject to certain
conditions, including the adoption of the merger agreement by our stockholders,
the receipt by us of a solvency opinion substantially to the effect that
BioVeris will not be insolvent after giving effect to the merger and related
transactions and the execution and delivery of the ongoing commercial
agreements, and that Roche will have loaned us up to $214 million, such loan
remaining the obligation of IGEN following the completion of the merger. All our
cash on hand will be transferred to BioVeris as part of the restructuring.

Upon completion of the merger, each outstanding share of our common stock will
be converted into the right to receive $47.25 in cash, without interest, and one
share of BioVeris common stock. In addition, upon completion of the merger, all
outstanding options granted under our stock option plans, including unvested
options, will be canceled and the holder of any such options will have the right
to receive for each share covered by such option cash from Roche equal to the
excess of $47.25 over the exercise price of such option (without interest) and
one share of BioVeris common stock.

Effective simultaneously with the completion of the merger, Roche will hold a
new worldwide, non-exclusive, fully-paid, royalty-free, license under patents
and technology that relate to detection methods and systems which employ
electrochemiluminescence (ECL) technology, but specifically excluding technology
related to gene amplification or compounds composed of or capable of binding
with nucleotides. The license may be used only in a specific field, generally
described here as the human in vitro diagnostics field, to develop, make,
reproduce, modify, use, sell and otherwise commercially exploit specified
products. Our rights, as licensor under the license agreement, will be
transferred to BioVeris as part of the restructuring.

As part of the merger and related transactions, we and Roche have entered into
an ongoing litigation agreement providing that all litigation between the
parties be suspended pending the completion of the merger (see Note 8). As
partial consideration for the ongoing litigation agreement and for Roche's use
of ORIGEN technology pending completion of the merger, Roche is obligated to pay
us a fixed monthly fee of $5.0 million which commenced in July 2003, and will be
payable until the completion of the merger. Effective July 1, 2003, there were
no further royalties owed to us under the Roche license agreement. In addition,
in July 2003 Roche paid us $18.6 million in cash for damages arising out of the
Maryland contract action.

                                       18



Overview

We and our licensees develop, manufacture and market products based on our
electrochemiluminescence technology, which we call ORIGEN. We believe that our
ORIGEN technology, which permits the detection and measurement of biological
substances, offers significant advantages over competing detection and
measurement methods by providing a unique combination of speed, sensitivity,
flexibility and throughput in a single technology platform. Our ORIGEN
technology is incorporated into our and our licensees' instrument systems and
reagents, which are the fluids used in the performance of tests, or assays, on
such instrument systems. In addition, we offer assay development and other
services used to perform analytical testing.

Our strategy for our ORIGEN technology has been and continues to be based on
entering into license arrangements and collaborations with third parties that
can assist in our commercialization efforts while at the same time directly
developing and commercializing our own products.

License Arrangements and Collaborations. We have entered into license
arrangements and collaborations with established health care companies to
commercialize our ORIGEN technology for clinical testing, which is the
diagnostic testing of patient samples to measure the presence of disease and
monitor medical conditions. Our licensees have developed multiple product lines
for this market based on our ORIGEN technology, and have sold or placed
approximately 9,000 ORIGEN-based systems with customers worldwide.

These sales and placements have been made predominantly by Roche, which uses our
ORIGEN technology for certain segments of the clinical testing market and is the
world's leading provider of clinical testing products. Roche has adopted our
ORIGEN technology for its Elecsys immunodiagnostic product line (see Roche
Transaction above).

Direct Commercialization Efforts. We also directly develop and commercialize our
ORIGEN technology. We have developed, and continue to develop, ORIGEN-based
products for the following worldwide markets. Many of our instruments and assays
have been and are being designed to serve customers across multiple markets.

     o    Biodefense and Industrial Testing - We are  commercializing our ORIGEN
          technology  for  use  in  the  emerging  markets  for  biodefense  and
          industrial  testing.  The biodefense  market includes products for the
          detection of bacteria,  viruses and toxins that may pose a military or
          public health threat.

          Over the past year,  we have  worked  with  numerous  departments
          within  the  Department  of Defense  (DOD) and other  U.S.  government
          agencies  to  develop  ORIGEN-based  products  for  the  detection  of
          biological  agents such as anthrax,  staphylococcus  enterotoxin B and
          botulinum toxin, among others. We are also  commercializing our ORIGEN
          technology for use in the emerging industrial market for the detection
          of foodborne and waterborne disease causing  pathogens.  We have begun
          to sell our first  products  for this market,  the  PATHIGEN  panel of
          tests for E. coli O157, Salmonella,  Campylobacter and Listeria, which
          we sell primarily as a quality  control test method to food producers,
          food processors and contract laboratories for the food industry.

                                       19





     o    Life Science - We are commercializing our ORIGEN technology for use in
          drug discovery and development that is performed by pharmaceutical and
          biotechnology    companies,    universities    and   other    research
          organizations.  Certain  of  our  ORIGEN-based  systems  are  used  by
          pharmaceutical  and  biotechnology  companies  in all  phases  of drug
          discovery, including:

     o    validating targets identified through genomics;

     o    screening   of  large   numbers   of   compounds   generated   through
          combinatorial chemistry;

     o    re-testing and optimization of lead compounds; and

     o    clinical trial testing of drug candidates.

We believe the  ORIGEN-based  systems  used in this  market  provide a number of
advantages  relative to other drug discovery  technologies,  including  enhanced
sensitivity and greater ease and speed of assay formatting.

     o    Clinical Testing - We are developing our ORIGEN  technology to be used
          in certain  fields in the clinical  testing  market,  particularly  to
          perform  tests in  decentralized  sites  outside of  central  hospital
          laboratories and clinical reference laboratories. Our present strategy
          is to focus our product  development  efforts on patient  care centers
          such as physicians'  offices,  ambulatory clinics,  hospital emergency
          rooms,   surgical  and  intensive  care  units,   hospital   satellite
          laboratories and nurses' stations.

We believe our ORIGEN technology permits development of a system that can
provide accurate results to a physician rapidly, thereby permitting the
physician to make a more timely decision regarding the patient's course of
treatment.

                                       20


Results of operations in the future are likely to fluctuate substantially from
quarter to quarter as a result of various factors, which include:

     o    the volume  and timing of orders  from our  customers  for  biodefense
          products,  M-SERIES systems or other products, which orders are placed
          from time to time by our customers based on their needs;

     o    the  timing  of  instrument  deliveries  and  installments,  which are
          generally  delivered  and installed  shortly  after the  instrument is
          ordered;


     o    the  success of  M-SERIES  system  upgrades  and  enhancements,  which
          upgrades and enhancements  involve increased product costs at the time
          of the upgrade or enhancement,  and product sales based on the success
          of the product for the customer;

     o    the amount of revenue  recognized  from  royalties and other  contract
          revenues,  which  revenues  are  dependent  upon  the  efforts  of our
          licensees and collaborators;

     o    whether our  instruments  are sold or leased to customers,  which will
          affect  the  timing of the  recognition  of  revenue  from the sale or
          lease;

     o    the timing of our  introduction  of new products,  which could involve
          increased expenses associated with product development and marketing;

     o    the volume and timing of product returns and warranty  claims,  which,
          if products are returned or have warranty  claims that are unexpected,
          may involve  increased costs in excess amounts reserved for returns or
          claims;

     o    our  competitors'  introduction of new products,  which may affect the
          purchase  decision  of,  or timing  of  orders  by our  customers  and
          prospective customers while the competitors' product is assessed;

     o    the amount of expenses we incur in  connection  with the  operation of
          our business,  including  costs  associated  with the Roche merger and
          related transactions,  research and development costs, which increases
          or  decreases  based on the  products  in  development  and  sales and
          marketing  costs,  which is  based on  products  being  introduced  or
          promoted from time to time;

     o    the volume of sales to POL  customers  pending  the  transfer of such
          customers' contracts back to Roche on consummation of the Roche merger
          and related transactions;

     o    unexpected  termination of government contracts or orders, which could
          result in decreased sales and increased costs due to excess  capacity,
          inventory personnel and other expenses;

     o    our share of losses  in MSD which are based on the  operations  of MSD
          over which we have limited control, which for the three and six months
          ended  September  30, 2003  totaled  $4.5  million  and $9.7  million,
          respectively,  compared to $5.0 million and $9.5 million for the three
          and six months ended September 30, 2002;

     o    the  continued  supply of the materials  that we use in our products;
          and

     o    our manufacturing capabilities.



                                       21



We have experienced significant operating losses each year since inception and
expect those losses to continue. Losses have resulted from a combination of
lower royalty revenue than we believe we were entitled to under the Roche
license agreement, costs incurred in research and development, Roche litigation
costs, our share of losses in affiliate, selling costs and other general and
administrative costs. We expect to incur additional operating losses as a result
of increases in expenses for manufacturing, marketing and sales capabilities,
research and product development, general and administrative costs and equity in
loss of affiliate, offset in part by lower Roche litigation costs and the $18.6
million court judgment Roche paid to us in connection with the Maryland contract
litigation.

Our ability to become profitable in the future will be affected by, among other
things, our ability to expand the commercialization of existing products;
upgrade and enhance the M-SERIES family of products; introduce new products into
the market; generate higher revenue; develop marketing, sales and distribution
capabilities cost-effectively; and continue existing collaborations or establish
successful new collaborations with corporate partners to develop and
commercialize products that incorporate our technologies.

For a description of the BioVeris business, you should refer to the registration
statement on Form S-4 filed in connection with the proposed transaction between
IGEN and Roche.

Results of Operations

Quarter and Six Months Ended September 30, 2003 and 2002.

Revenues. Total revenues were $40.4 million and $57.5 million for the quarter
and six months ended September 30, 2003, an increase of $27.0 million and $32.1
million, respectively, from $13.4 million and $25.4 million for the
corresponding prior year periods. The revenue growth was due primarily to the
$18.6 million court judgment Roche paid to us in connection with the Maryland
contract litigation between the companies, as well as to increases in product
sales and revenue from Roche Diagnostics (Roche revenue).

Roche revenue is comprised of revenues earned by us from Roche, including:

     o    A  fixed  monthly  fee of $5.0  million  for  the  use of  ORIGEN
          technology.  The fixed  monthly fee commenced in July 2003 and will be
          payable to us until the completion of the merger;

     o    Royalties paid under the 1992 license  agreement  between us and Roche
          for the period through June 30, 2003,  which are no longer required as
          a result of a new  agreement  between the parties  that  provides  for
          fixed  monthly  payments,   as  described  above;

     o    Fees  earned  in  connection  with  our  performance  under  an  assay
          development contract with Roche.

Roche revenue was $15.3 million and $26.7 million for the quarter and six months
ended  September  30,  2003,  an  increase of $6.9  million  and $10.1  million,
respectively,  from $8.4 million and $16.6 million for the  corresponding  prior
year periods.  These  increases were  primarily due to the $5.0 million  monthly
fee, which was greater than royalties earned for quarters through June 30, 2003.

                                       22



Product sales were $6.2 million and $11.6 million for the quarter and six months
ended  September  30, 2003,  an increase of $1.5 million  (31%) and $3.3 million
(40%),  respectively,  from $4.7 million and $8.3 million for the  corresponding
prior year periods.  This growth in product  sales was  primarily  from sales of
biodefense  products which  increased  $1.1  million and $2.1  million to $1.9
million and $3.3  million for the quarter  and six months  ended  September  30,
2003, as well as sales of products for the life science  market which  increased
$500,000  and $1.3  million to $3.8 million and $7.1 million for the quarter and
six months  ended  September  30, 2003.  We  anticipate  continued  increases in
biodefense related sales as a result of our ongoing biodefense  initiatives.  We
have a  contract  with  the DOD  which we  entered  into in June  2003,  for the
production  of tests for the  detection  of  specific  toxins  in  environmental
samples. Under the contract the government may, at its option, make purchases of
up to $23.0  million over a period of up to four years,  with up to $7.0 million
of product  sales  through June 2004, of which $1.7 million were sold during the
quarter ended  September 30, 2003.  For each contract year after June 2004,  the
DOD, at its option, may elect to purchase products from us but has no obligation
to  do  so.  Sales  to  physician   office   laboratory   (POL)  customers  were
approximately  $500,000  and $1.2  million for the quarter and six months  ended
September  30, 2003,  a decrease of  approximately  $100,000 in each  respective
period.  These POL  customers  are being served by us under the terms of a court
order related to Roche selling  outside their licensed field and these customers
will remain with IGEN when the proposed Roche transaction is completed.

Royalty and contract fees that are unrelated to Roche were $300,000 and $600,000
for the quarter and six months ended September 30, 2003, respectively, unchanged
from the corresponding prior year periods. These fees relate primarily to
royalties received in connection with license arrangements for ORIGEN technology
with Eisai and BioMerieux.

Operating Costs and Expenses. Product costs were $3.5 million (57% of product
sales) and $6.2 million (53% of product sales) for the quarter and six months
ended September 30, 2003, and $2.2 million (47% of product sales) and $3.5
million (43% of product sales) for the corresponding prior year periods. Product
costs, as a percentage of product sales in the current year, increased due to
costs incurred in connection with the launch of our new M-SERIES 384 instrument
and upgrades of detection modules for our existing life science customers.

Research and development expenses were $5.1 million and $10.5 million for the
quarter and six months ended September 30, 2003, a decrease of $1.2 million
(20%) and $1.6 million (13%), respectively, from $6.3 million and $12.1 million
in the corresponding prior year periods. This decrease was due primarily to
lower personnel and facilities costs for development projects. Research and
development expenses relate primarily to ongoing development costs and product
enhancements associated with the M-SERIES family of products, development of new
assays and research and development of new systems and technologies, including
clinical point-of-care products. We expect research and development costs to
increase as product development and core research continue to expand, including
costs associated with our efforts in developing biodefense testing products.

Selling, general and administrative expenses were $5.9 million and $12.0 million
for the quarter and six months ended September 30, 2003, a decrease of $400,000
(7%) and 300,000 (2%), respectively, from $6.3 million and $12.3 million for
the corresponding prior year periods. These decreases were primarily
attributable to lower personnel costs in the current year periods.

                                       23



Costs related to our litigation and the proposed transaction with Roche, which
include financial and legal advisory fees were $4.3 million and $7.9 million for
the quarter and six months ended September 30, 2003, an increase of $3.4 million
and $5.9 million, respectively, from $900,000 and $2.0 million for the
corresponding prior year periods. These increases reflect costs incurred related
to the continuing Roche litigation, patent infringement actions filed by us
against Roche in the United States and Europe, and legal fees and related costs
associated with the proposed transaction with Roche.

Interest and Other Expense. Interest and other expense, net of interest income,
were $3.4 million and $4.6 million for the quarter and six months ended
September 30, 2003, an increase of $2.4 million and $2.9 million, respectively,
from $1.0 million and $1.7 million in the corresponding prior year periods.
These increases resulted primarily from a one-time, non-cash interest charge of
approximately $2.4 million related to the unamortized debt discount on the
convertible debentures that were converted in September 2003 into our common
stock.

Equity in Loss of Affiliate. MSD is a joint venture formed by MST and us in
1995. MSD was formed for the development, manufacture, marketing and sale of
products utilizing a combination of MST's multi-array technology together with
our technology. In conjunction with entering into the MSD agreements and taking
into account the progress made by MSD in the development of its products, we
determined that future contributions to MSD would be made based on the future
investment benefit we expect to obtain. Accordingly, our contributions to MSD
since July 1, 2001 have been recorded as Investment in Affiliate and as
substantially all of MSD's funding was provided by IGEN, we have recorded
approximately 100% of MSD's losses as Equity in Loss of Affiliate. For the
quarter and six months ended September 30, 2003, our Equity in Loss of Affiliate
was $4.5 million and $9.7 million compared to $5.0 million and $9.5 million in
the corresponding prior year periods. MSD's losses changed during the quarter
and six months ended September 30, 2003 due to its transition from a development
stage entity to an operating company. MSD had not commenced commercial
operations during the six months ended September 30, 2002 and its product sales
commenced in October 2002. The changes in MSD's losses during the quarter and
six months ended September 30, 2003 result primarily from increases in sales and
marketing expenses offset by the growth in revenues.

As of September 30, 2003, MSD had cash and short-term investments of $5.0
million with working capital of $8.6 million. During the six months ended
September 30, 2003, MSD used $2.7 million for the purchase of inventory and $2.4
million for the purchase of property, equipment and leasehold improvements. See
"Liquidity and Capital Resources" for a discussion of our future funding
commitments to MSD.

Net Income (Loss). The net income was $13.8 million ($0.57 per basic common
share and $0.55 per diluted common share) for the quarter compared to a net loss
of $8.3 million ($0.35 per basic and diluted common share, after consideration
of the effect of preferred dividends) in the corresponding prior year quarter.
The net income was $6.6 million ($0.28 per basic common share and $0.26 per
diluted common share) for the six months ended September 30, 2003 compared to a
net loss of $15.7 million ($0.68 per basic and diluted common share, after
consideration of the effect of preferred dividends) in the corresponding prior
year period. The earnings improvement from the prior periods is primarily due to
the $18.6 million Roche litigation judgment, increased Roche revenue and growth
in product sales.

                                       24



Liquidity and Capital Resources

We have financed operations through the sale of preferred and common stock, debt
financings and the placement of convertible debentures. In addition, we have
received funds from research and licensing agreements, sales of our ORIGEN line
of products and royalties from product sales by licensees. As of September 30,
2003, we had $49.8 million in cash, cash equivalents and short-term investments
with working capital of $34.7 million.

Net cash provided by operations was $33.3 million for the six months ended
September 30, 2003 compared to net cash used in operations of $8.7 million for
the corresponding prior year period. This increase in cash provided was
primarily due to our net income in the current period. We have made a commitment
with a supplier to purchase approximately $800,000 of instrumentation through
January 2004, primarily for use in supplying our biodefense customers.

We used $900,000 and $2.0 million of cash for the acquisition of equipment and
leasehold improvements during the six months ended September 30, 2003 and 2002,
respectively, and our investments in MSD were $15.3 million and $10.8 million
during the same respective periods. We believe material commitments for capital
expenditures and additional or expanded facilities may be required in a variety
of areas, such as product development programs. We are evaluating new facilities
for development, manufacturing and other corporate uses and are in negotiations
to secure new space, which if concluded, would result in additional facilities
costs. We have not, at this time, made material commitments for any such capital
expenditures or facilities and have not secured additional sources, if
necessary, to fund such commitments. If we were unable to fund such commitments,
we may have to scale back or even eliminate some programs or plans.

Net cash used for financing activities was $1.5 million and $3.9 million for the
six months ended September 30, 2003 and 2002, respectively. These uses of funds
were due to debt service of $2.7 million and $2.5 million, for the six months
ended September 30, 2003 and 2002, respectively, offset by the issuance of
common stock from the exercise of stock options that provided proceeds of $1.2
million and $400,000, for the six months ended September 30, 2003 and 2002,
respectively. The prior year period also included Series B Convertible Preferred
Stock dividend payments of $3.4 million and the receipt of $1.6 million
resulting from the repayment of a loan. During the year ended March 31, 2003,
all shares of Series B Convertible Preferred Stock were converted into common
stock and there are no remaining shares of Series B Convertible Preferred Stock
outstanding.

As of September 30, 2003, our material future obligations were as follows:

MSD is a joint venture formed by MST and us in 1995.  Under the MSD  agreements,
our  funding  commitment  is based on an  annual  budget  of MSD  approved  by a
committee of our board of directors consisting of independent  directors (JVOC).
The JVOC  approved  funding for MSD by us for the period from January 1, 2003 to
November 30, 2003 in an amount of $20.6 million, subject to a permitted variance
of 15%. As of September 30, 2003,  our remaining  funding  commitment to MSD was
$5.4 million. IGEN's funding commitment may be satisfied in part through in-kind
contributions of scientific and administrative  personnel and shared facilities.
For  the  six  months  ended   September  30,  2003  and  2002,  we  made  total
contributions to MSD of $15.3 million and $10.8 million, respectively, including
$3.7  million  in the  current  period  which  related to the  permitted  budget
variances from prior years. Operating leases in the table above excludes amounts
expected to be allocated to MSD to meet a portion of our funding commitment.  In
addition, in the event the merger is not completed prior to December 1, 2003, we
have agreed to provide  continued interim funding to MSD, payable monthly on the
first day of each month  commencing  on  December  1, 2003 until the  earlier to
occur of completion of the merger or  termination of the merger  agreement.  The
monthly funding will equal  approximately  $1.7 million,  which is 1/12th of our
aggregate funding commitment under the 2003 MSD budget approved by the JVOC. Any
interim funding will reduce the amount of BioVeris's final capital  contribution
following completion of the merger. Upon completion of the merger, the MSD joint
venture agreement will expire. Following completion of the merger, BioVeris will
use its cash to make a final  capital  contribution  of $37.5 million to MSD. Of
the final capital  contribution  of $37.5  million,  any amount in excess of $30
million will be funded by IGEN's and  BioVeris's  chairman  and chief  executive
officer through the purchase of shares of BioVeris Series B preferred stock that
will  economically  mirror the Class C interests  in MSD to be held by BioVeris.
BioVeris's obligation to make this final capital contribution to MSD is separate
from IGEN's  obligation to provide funding to MSD through  November 30, 2003, as
described above.

We hold 31% voting equity interest in MSD and are entitled to a preferred return
on $72.2 million of the funds previously invested by us in MSD through September
30, 2003 and on all additional funds invested by us thereafter. This preferred
return would be payable out of a portion of both future profits and certain
third-party financings of MSD, generally before any payments are made to other
equity holders.

As part of the merger and related transactions, we, BioVeris and MSD agreed that
the MSD joint venture agreement will expire on the later of (1) November 30,
2003, or (2) the earlier of (a) the date of the completion of the merger or (b)
the termination of the merger agreement. We, BioVeris and MSD also agreed that
funding for MSD would not be extended other than pursuant to the agreements
related to the merger and related transactions. In addition, in accordance with
the MSD agreements, MST and MSD have the right to terminate the MSD joint
venture agreement prior to its expiration under certain circumstances, including
(1) breach of our obligations, including our funding obligations to MSD, (2)
MSD's termination of Jacob Wohlstadter's employment (other than for cause or
disability), (3) if Jacob Wohlstadter is entitled to terminate his employment
agreement for good reason (as defined in his employment agreement) or (4) upon a
change in control of us, as defined. MSD, MST and Jacob Wohlstadter have each
agreed that the merger and related transactions will not constitute a change in
control for purposes of the MSD agreements and the Jacob Wohlstadter employment
agreement.

Upon the expiration of the MSD joint venture agreement as a result of the
completion or termination of the proposed transaction with Roche or the
expiration or termination of the MSD joint venture agreement for any other
reason, MSD and MST have the right to purchase our or BioVeris's, as the case
may be, entire interest in MSD for a purchase price equal to fair market value
(to be determined in accordance with the provisions and procedures set forth in
the MSD agreements, which shall include a determination by appraisers if the
parties are unable to agree on fair market value) minus a discount factor
varying from 7.5% to 15%. If MSD or MST exercises this right, it will be
entitled to pay us or BioVeris, as the case may be, the purchase price, plus
simple, cumulated but not compounded, interest at the fixed annual rate of 0.5%
over the prime rate in effect on the date MSD or MST, as the case may be, elects
to purchase the interests.

                                       26




The purchase price is payable over time in installments equal to the sum of 5%
of MSD net sales, as determined in accordance with the MSD agreements, and 20%
of the net proceeds realized by MSD from the sale of debt or equity securities
in any third-party financing after the date of the sale of our or BioVeris's, as
the case may be, interest in MSD. As security for the payment obligation,
BioVeris will hold a security interest in the interests in MSD that are being
purchased. MST or MSD, as the case may be, may repay all or any part of the
outstanding purchase price plus accrued interest at any time and from time to
time without penalty.

Following the expiration or termination of the MSD joint venture agreement,  MSD
will be entitled to continue to lease certain  facilities and related  equipment
from us or  BioVeris,  as the  case  may be,  (including  laboratory  facilities
located  in our  corporate  headquarters)  pursuant  to the  terms  of  existing
sublease  agreements  with MSD.  The term of each  sublease  will expire one day
prior  to the  expiration  of the  prime  lease  for  that  facility.  Following
termination or expiration of the MSD joint venture agreement,  we, BioVeris,  as
the case may be, or MSD  unilaterally  may terminate any or all of the subleases
by providing at least 18 months prior written  notice of  termination.  If we or
BioVeris, as the case may be, elects to terminate a sublease for a facility, MSD
may elect to remain in that facility  after the 18 month period  expires for any
period  of time  selected  by MSD,  but not  longer  than  one day  prior to the
expiration of the prime lease (including any extenstions of the prime lease). We
or  BioVeris,  as the case may be, have an  obligation  to MSD to  exercise  all
available  extension rights under lease agreements which are subject to sublease
arrangements  with MSD.  After a notice of  termination  of a sublease  has been
sent,  MSD  will be  required  to pay its pro rata  share of all rent and  other
expenses  incurred by us or BioVeris, as the case may be, under our prime lease.
MSD and MST may  elect,  if  either  exercises  its  right  to  purchase  our or
BioVeris's,  as the case may be,  interests in MSD, to have its rent and expense
payment  obligations  for the 18 month period  included in the purchase price of
those interests in MSD.

Following the expiration of the MSD joint venture agreement, many of our or
BioVeris's, as the case may be, licenses and other arrangements with MSD and MST
will continue indefinitely in accordance with their terms.

MSD has an employment agreement with Jacob Wohlstadter, its President and Chief
Executive Officer, the current term of which runs through November 30, 2004, and
provides for a salary of $250,000 for the year ending December 31, 2003. In
addition, Jacob Wohlstadter is also eligible to receive, at the discretion of an
independent committee of our board of directors, an annual cash bonus in an
amount not to exceed 20% of his annual salary. Jacob Wohlstadter is also
entitled to receive pension, welfare and fringe benefits comparable to those
received by senior executives of IGEN and other insurance and retirement
benefits. If MSD terminates the employment agreement without cause, or Jacob
Wohlstadter terminates the employment agreement for good reason (which includes
a "change in control" of IGEN, as defined), Jacob Wohlstadter shall be entitled
to receive, in addition to salary and pro rata bonus and adjustments earned
through the 60th day following the notice of termination, an amount equal to
from 3 to 12 times (depending on the reason for the termination) the monthly pro
rata salary, bonus and adjustments in effect at the time of the termination. In
addition, he is entitled to a gross-up for any "parachute" excise tax that may
be imposed on payments made or benefits provided pursuant to the agreement. We
are responsible for all amounts payable, costs incurred and other obligations
under the employment agreement, which generally are expected to be paid out of
our funding commitment to MSD.

Under the terms of our ongoing litigation  agreement with Roche, we have agreed,
pending  the  completion  of  the  proposed  Roche  transaction,   to  stay  the
enforcement of our termination  rights under the Roche license agreement and the
pending  patent  infringement  actions that we filed against Roche in the United
States  and  Germany.  In  the  event  the  proposed  Roche  transaction  is not
completed,  we may, at our option,  enforce termination of the license agreement
and  resume  our  patent  infringement  actions  against  Roche.  If  the  Roche
transaction  is not  consummated  and the monthly  payments of $5.0 million from
Roche to us under our ongoing litigation agreement were to cease, our results of
operations and cash flows would be materially  adversely  affected  unless,  and
until,  we enter into one or more strategic  partnerships  with other  companies
that are able to develop and  commercialize  diagnostic  instruments in a manner
that provides comparable revenues to us.

While we are highly confident that the proposed Roche transaction will close, we
cannot assure you that it will be completed or that, if not completed, we will
be able to enter into one or more strategic partnerships on favorable terms, if
at all.

We have a substantial amount of indebtedness, and there is a possibility that we
may be  unable to  generate  cash or  arrange  financing  sufficient  to pay the
principal  of,  interest on and other  amounts due with respect to  indebtedness
when  due,  or in  the  event  any  of  it  is  accelerated.  In  addition,  our
indebtedness may require that we dedicate a substantial  portion of our expected
cash flow from operations to service indebtedness, which would reduce the amount
of expected cash flow available for other  purposes,  including  working capital
and capital expenditures.


                                       27




On July 9, 2003,  the Appellate  Court affirmed our right to terminate the Roche
license agreement and we immediately  issued a notice confirming  termination of
that agreement.  Termination of the Roche license  agreement led to, among other
things,  termination of our right to receive royalty  payments from Roche on its
net sales of  products  based on our ECL  technology.  In  conjunction  with the
proposed  Roche  transaction,  Roche is paying a fixed fee of $5.0  million  per
month to us for the use of ECL  technology  pending  completion  of the proposed
Roche  transaction.Termination  of the Roche  license  agreement  is an event of
default under the 8.5% Senior Secured Notes  (Notes).  Pursuant to the agreement
under which the Notes were  issued,  if an event of default has  occurred and is
continuing, the holder of the Notes may declare all of the Notes immediately due
and  payable.  If  accelerated,  we  would  be  obligated  to pay the  remaining
principal  amount due of $15.4  million as of September  30, 2003,  plus accrued
interest and a make-whole  amount. The holder of the Notes has indicated that it
is not  planning  to declare an event of  default or  accelerate  payment of the
Notes pending the closing of the proposed Roche transaction.  We intend to repay
in full the Notes  prior to the  completion  of the  proposed  Roche  merger and
related transactions.

We need substantial amounts of money to fund operations. In this regard, from
time to time we have discussions with third parties, including multinational
corporations, regarding various business arrangements including distribution,
marketing, research and development, joint venture and other business
agreements, which could provide for up-front fees or payments. In the event that
the proposed Roche transaction did not close, we would evaluate the advisability
and feasibility of a variety of financing alternatives, including issuance of
additional debt or equity securities.

We cannot assure you that we will successfully complete any of the foregoing
arrangements and access to funds could be adversely impacted by many factors,
including the failure to complete the proposed Roche transaction, the volatility
of the price of our common stock, continuing losses from operations,
establishment of new business arrangements, the status of new product launches,
general market conditions and other factors.

We believe that our existing capital resources, together with revenue from each
monthly fee from Roche and other royalties, product sales and contract fees will
be adequate to fund operations through the middle of calendar year 2004. If we
are unable to raise additional capital, or in the event the proposed Roche
transaction was not completed, we may have to scale back, or even eliminate,
some programs. Alternatively, we may consider pursuing arrangements with other
companies, such as granting licenses or entering into joint ventures or
collaborations, on terms that may not be favorable to us.

As of September 30, 2003, we had no off-balance sheet arrangements.

Critical Accounting Policies

A critical accounting policy is one that is both important to the portrayal of
our financial position and results of operations and requires the application of
difficult, subjective or complex judgments by our management. As a result, they
are subject to an inherent degree of uncertainty. In applying those policies,
our management uses its judgment to determine the appropriate assumptions to be
used in the determination of certain estimates. These estimates are based on our
historical experience, terms of existing contracts, our observance of trends in
the industry, information provided by our customers, and information available
from other outside sources, as appropriate. Our significant accounting polices
include:

Revenue Recognition - We derive revenue principally from three sources: product
sales, royalty income and contract fees.

Product sales revenue is recognized when persuasive evidence of an arrangement
exists, the price to the buyer is fixed and determinable, collectibility is
reasonably assured and the product is shipped to the customer thereby
transferring title and risk of loss. Rental revenue associated with instruments
that are leased is recognized ratably over the life of the lease agreements.
Revenue associated with extended warranty arrangements is recognized over the
term of the extended warranty contract. Royalty income is recorded when earned
based on information provided by licensees.

Revenue from services performed under contracts is recognized over the term of
underlying customer contract or at the end of the contract, when obligations
have been satisfied. For services performed on a time and material basis,
revenue is recognized upon performance. Amounts received in advance of
performance under contracts are recorded as deferred revenue until earned.

The majority of our product sales and contract fees contain standard terms and
conditions. Certain transactions may contain negotiated terms that require
contract interpretation to determine the appropriate amount of revenue to be
recognized. In addition, we must assess whether collectibility is reasonably
assured. While management believes its interpretations and judgments are
reasonable, different assumptions could result in changes in the timing of
revenue recognition.

Joint Venture Accounting - We account for our ownership in the MSD joint venture
based on the equity method as we have determined that we do not control MSD's
operations. Factors considered in determining our level of control include the
fact that we own less than 50% of the voting equity interest in MSD; that we do
not have exclusive authority over MSD decision making and have no ability to
unilaterally modify the MSD joint venture agreements; and that we have the right
to appoint only one out of two seats on MSD's board of managers. A different
assessment of these factors could provide for the use of consolidation
accounting rather than the equity method, in which case a consolidation of our
financial statements with those of MSD would be appropriate. Consolidation
accounting would require certain reclassifications within our consolidated
financial statements but would not materially effect our financial position or
net loss.

                                       29



In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" (FIN 46). FIN 46 provides guidance on variable
interest entities and the framework through which an enterprise assesses
consolidation of variable interest entities. We have adopted FIN 46 and have
determined that MSD qualifies as a variable interest entity under FIN 46 because
substantially all of MSD's funding is being provided by us and our voting rights
are not proportional to our obligation to absorb a majority of the potential
future losses of MSD. Accordingly, beginning October 1, 2003, we will
consolidate the financial results of MSD. Consolidation accounting will require
certain reclassifications within our consolidated financial statements but is
not expected to materially effect our financial position or net loss as we have
recorded approximately 100% of MSD's losses. See Recent Accounting
Pronouncements below.

Available For Sale Securities - Our short-term investments consist primarily of
corporate debt securities that classified as "available for sale". These
securities, which are all due within one year, have readily determinable fair
values accounted or at their fair market value in the balance sheets, and
unrealized gains and losses on these securities, if any, are reported in
accumulated other comprehensive loss in stockholders' equity until realized. All
of our "available for sale" securities are included in current assets as
management considers the securities readily available to fund current
operations.

If we held investments that were classified as "held-to maturity" securities,
these would be carried at amortized cost rather than at fair market value. If we
held investments that were classified as "trading" securities, these would be
carried at fair market value, with a corresponding adjustment to earnings for
any change in fair market value.

Allowance for Doubtful Accounts - We maintain reserves on customer accounts
where estimated losses may result from the inability of our customers to make
required payments. These reserves are determined based on a number of factors,
including the current financial condition of specific customers, the age of
accounts receivable balances and historical loss rates. If the financial
condition of our customers were to deteriorate, resulting in an impairment of
their ability to make payments, an additional allowance may be required.

Inventory  - We carry our  inventory  at the  lower of cost or market  using the
first-in, first-out method. We regularly review inventory quantities on hand and
record a reserve  for  excess  and  obsolete  inventory  based  primarily  on an
estimated  forecast of product demand and production  requirements  for the next
twelve months. Reserves are recorded for the difference between the cost and the
market value. Those reserves are based on significant  estimates.  Our estimates
of future product  demand may prove to be inaccurate,  in which case we may have
understated  or  overstated  the  provision  required  for excess  and  obsolete
inventory.  In addition,  our industry is characterized by technological change,
frequent new product  development and product  obsolescence that could result in
an increase in the amount of obsolete inventory  quantities on hand. Although we
make every  effort to ensure the  accuracy of our  forecasts  of future  product
demand,  any  significant  unanticipated  changes  in  demand  or  technological
developments  could have a significant impact on the values of our inventory and
our reported operating results.


                                       30




Evaluation of Long-lived Assets - We have different long-lived assets recorded
on our balance sheet that include equipment and leasehold improvements,
investments and other assets. We evaluate the potential impairment of long-lived
assets whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be fully recoverable. In evaluating the
recoverability of an asset, management's policy is to compare the carrying
amount of an asset with the projected undiscounted future cash flow. While
management believes that estimates are reasonable and that no impairment of
these assets exists, different assumptions could affect these evaluations and
result in impairment charges against the carrying value of these assets.

Warranty Reserve - We warrant our products against defects in material and
workmanship for one year after sale and record estimated future warranty costs
at the time revenue is recognized. A reserve for future warranty claims is
recorded based upon management's review of historical results, supplemented by
expectations of future costs. Unanticipated changes in actual warranty costs
could impact our operating results.

Capitalized  Software Costs - We capitalize software  development costs incurred
after  technological  feasibility is established in accordance  with SFAS No. 86
"Accounting for the Costs of Computer Software to be Sold,  Leased, or Otherwise
Marketed." We apply our judgment in determining  when software  being  developed
has reached  technological  feasibility,  and at that point we would  capitalize
software development costs. To date, software development has been substantially
completed concurrently with the establishment of technological feasibility,  and
accordingly, no costs have been capitalized to date.

Recent Accounting Pronouncements.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" (FIN 46). FIN 46 provides guidance on variable
interest entities and the framework through which an enterprise assesses
consolidation of a variable interest entity. FIN 46 was effective immediately
for variable interest entities created or acquired after January 31, 2003. In
October 2003, the FASB issued Staff Position FIN 46-6, which extended the
effective date of FIN 46 for variable interest entities created or acquired
before February 1, 2003 to the first interim or annual period ending after
December 15, 2003. We have adopted FIN 46 and have determined that MSD qualifies
as a variable interest entity under FIN 46 because substantially all of MSD's
funding is being provided by us and our voting rights are proportional to our
obligation to absorb a majority of the potential future losses of MSD.
Accordingly, beginning October 1, 2003, we will consolidate the financial
results of MSD. Consolidation accounting will require certain reclassifications
within our consolidated financial statements but is not expected to materially
affect our financial position or net loss, as we have recorded approximately
100% of MSD's losses.

In April 2003, the FASB issued SFAS No. 149, "Amendment of SFAS No. 133 on
Derivative Instruments and Hedging Activities" (SFAS 149). SFAS 149 amends and
clarifies accounting for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities under SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities".

                                      31




The amendments set forth in SFAS 149 improve financial reporting by requiring
that contracts with comparable characteristics be accounted similarly. SFAS 149
is effective for contracts entered into or modified after June 30, 2003 and for
hedging relationships designated after June 30, 2003. The implementation of SFAS
149 did not have a material effect on our financial position or results of
operations.

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity" (SFAS 150).
SFAS 150 establishes standards regarding the classification and measurement of
certain financial instruments with characteristics of both liabilities and
equity. SFAS 150 is effective for financial instruments entered into or modified
after May 31, 2003, and otherwise is effective at the beginning of the first
interim period beginning after June 15, 2003. The implementation of SFAS 150 did
not have a material effect on our financial position or result of operations.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Changes in interest rates do not affect interest expense incurred on our
long-term borrowing because it bears interest at a fixed rate. The principal
terms of this debt are as follows:

     o    Note payable with John Hancock  Life  Insurance  Company:  $30 million
          principal ($15.4 million principal at September 30, 2003), 8.5% Senior
          Secured Notes secured by future royalty  revenue from Roche,  maturing
          in March 2006 with  quarterly  principal and interest  payments. (See
          Item 1- Notes to Condensed Consolidated Financial Statements- Note 5)

However, we run a risk that market rates will decline and that the interest rate
will exceed those based on the then-current market rate. We are currently not
using interest rate derivative instruments to manage our exposure to interest
rate changes.

Interest income earned on our investment portfolio is affected by changes in the
general level of interest rates. We have invested excess cash generally in
securities of the U.S. Treasury, money market funds, certificates of deposit and
corporate bonds.

We invest excess cash in accordance with a policy approved by our board of
directors. This policy is designed to provide both liquidity and safety of
principal. The policy limits investments to certain types of instruments issued
by institutions with strong investment grade credit ratings and places
restrictions on our investments by terms and concentrations by type and issuer.

Given the amount invested as of September 30, 2003, a 1% change in the LIBOR
rate would not have a material effect on our interest income.

We are exposed to changes in exchange rates where we sell direct in local
currencies, primarily in the United Kingdom and Germany. Certain other foreign
sales are denominated in U.S. dollars and have no exchange rate risk. Gains and
losses resulting from foreign currency transactions have historically not been
material.

                                       32




ITEM 4:  CONTROLS AND PROCEDURES

IGEN management,  including the Chairman of the Board & Chief Executive  Officer
(serving as the principal  executive officer) and Chief Financial Officer,  have
conducted  an  evaluation  of  the  effectiveness  of  disclosure  controls  and
procedures  as of the end of the period  covered by this  report.  Based on that
evaluation,  the Chairman of the Board & Chief  Executive  Officer and the Chief
Financial Officer have concluded that the disclosure controls and procedures are
effective in ensuring that all material information required to be filed in this
quarterly  report  has been made known to them in a timely  fashion.  There have
been no significant changes in internal controls, or in other factors that could
significantly  affect  internal  controls during the quarter ended September 30,
2003 or  subsequent  to the date the  Chairman  of the  Board & Chief  Executive
Officer and the Chief Financial Officer completed their evaluation.
