ITEM 2.  ACQUISITION OF ASSETS.

         On March 19, 2001, Bio-Technology General Corp. ("BTG") acquired Myelos
Corporation, a privately-held biopharmaceutical company focused on the
development of novel therapeutics to treat diseases of the nervous system. Under
the terms of the acquisition agreement, BTG paid Myelos shareholders $35 million
in a combination of cash and stock ($14 million in cash and $21 million through
the issuance of 2,344,657 shares of BTG common stock (based on a value of
$8.9564, representing the average closing price of BTG's common stock for the 20
trading day period ending one day prior to the February 21, 2001 date the
acquisition agreement was executed)).

         In the event that (i) BTG publicly announces that it will file a New
Drug Application ("NDA") related to the use of PROSAPTIDE -TM- to treat
neuropathic pain or neuropathy, (ii) BTG receives minutes of the United
States Food and Drug Administration ("FDA") stating that the clinical data
possessed by BTG is sufficient for an NDA filing for the use of PROSAPTIDE to
treat neuropathic pain or neuropathy without requiring any further testing or
(iii) BTG initiates preparation of an NDA for PROSAPTIDE for the treatment of
neuropathic pain or neuropathy (the date the earliest of the foregoing occurs
being the "Payment Trigger Date"), then BTG shall pay to the Myelos
shareholders an additional $30 million, at least approximately $14 million of
which must be paid in shares of BTG common stock, valued at the average of
the closing prices of BTG common stock during the 20 trading days ending on
the Payment Trigger Date, and the remainder will be paid in cash, shares of
BTG common stock, or a combination thereof, as determined by BTG in its sole
discretion.

         In addition, in the event that the FDA approves the sale of PROSAPTIDE
for the treatment of neuropathic pain or neuropathy, BTG will pay the Myelos
shareholders 15% of the net sales of PROSAPTIDE for the treatment of neuropathic
pain or neuropathy during the 12 month period beginning on the earlier of (i)
the 25th full month after commercial introduction of PROSAPTIDE in the United
States for the treatment of neuropathic pain or neuropathy and (ii) April 1,
2010. At least 50% of this payment must be paid in shares of BTG common stock,
valued at the average of the closing prices of BTG common stock during the 20
days ending one day prior to the payment, and the remainder will be paid in
cash, shares of BTG common stock, or a combination thereof, as determined by BTG
in its sole discretion.

         In no event will BTG be obligated to issue in aggregate to the Myelos
shareholders more than 10,962,000 shares of BTG common stock. Any amount of the
contingent payments that cannot be paid in shares of BTG common stock shall
instead be paid in shares of BTG's preferred stock. The preferred stock will be
non-voting, non-convertible, non-transferable, non-dividend paying (except to
the extent a cash dividend is paid on the BTG common stock), with no mandatory
redemption for a period of 20 years and one day from the closing date of the
acquisition, and a right to share in proceeds in liquidation, up to the
liquidation amount.

         The transaction was treated as a "purchase" for accounting purposes.
The purchase price for accounting purposes is approximately $33,000,000, based
on a value for the approximately 2,344,700 shares of Company common stock issued
in the acquisition of $8.1172, representing the average closing price of the
Company's common stock for the four day period preceding the date the terms of
the acquisition were agreed to (February 21, 2001). In connection with the
Merger and based on an independent valuation, BTG allocated $45,600,000 to
in-process research and development projects of Myelos, representing the
estimated fair value based on risk-adjusted cash flows of the acquired
technology. At the date of the Merger the technology acquired in the acquisition
was not fully commercially developed and had no alternative future uses.
Accordingly, the value was expensed as of the acquisition date. The Company
recorded negative goodwill of $18,357,000 on its balance sheet, primarily
because the amount written off as in-process research and development acquired
exceeded the


                                      1



purchase price for accounting purposes. This negative goodwill will be amortized
over its expected useful life of five years.

                         Report of Independent Auditors


The Board of Directors and Stockholders
Myelos Corporation

We have audited the accompanying balance sheets of Myelos Corporation
(a development stage company) as of December 31, 2000 and 1999, and the related
statements of operations, stockholders' equity, and cash flows for the years
then ended, and for the period December 1, 1994 (inception) through December 31,
2000. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. The financial statements for the period December
1, 1994 (inception) through December 31, 1998, were audited by other auditors
whose report dated March 12, 1999, expressed an unqualified opinion on those
statements. The financial statements for the period December 1, 1994 (inception)
through December 31, 1998, include a net loss of $11,054,344. Our opinion on the
statements of operations, stockholders' equity, and cash flows for the period
December 1, 1994 (inception) through December 31, 2000, insofar as it relates to
amounts for prior periods through December 31, 1998, is based solely on the
report of other auditors.

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

In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material respects,
the financial position of Myelos Corporation, at December 31, 2000 and 1999, and
the results of its operations and its cash flows for the years then ended and
the period from December 1, 1994 (inception) through December 31, 2000, in
conformity with accounting principles generally accepted in the United States.

As discussed in Note 1 to the financial statements, the Company's recurring
losses from operations raise substantial doubt about its ability to continue as
a going concern. Management's plans as to these matters are also described in
Note 1. The 2000 financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

                          Notes to Financial Statements

                                December 31, 2000


1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BUSINESS

Myelos Corporation (the "Company") is a privately held company incorporated in
California on December 1, 1994. The Company develops technology and products
based on inventions both licensed from the University of California, San Diego
and developed in its own laboratory. The Company is developing potential
therapeutic products based on stimulatory peptides of several key cytokines
primarily for use in treating diseases and disorders of the peripheral and
central nervous systems. As of December 31, 1999, the Company completed a "Phase
II" clinical trial on its lead compound Prosaptide-TM- TX14(A).

The Company is a development stage company in the initial stage of its
operations, and since inception, the Company has been engaged in organizational
activities, including recruiting personnel, establishing office facilities,
research and development and obtaining financing. Since inception, and through
December 31, 2000, the Company has incurred losses of $19,837,082.

BASIS OF PRESENTATION

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. This basis of accounting contemplates
the recovery of the Company's assets and the satisfaction of its liabilities in
the normal course of business. Successful completion of the Company's
development program and its transition to attaining profitable operations is
dependent upon obtaining financing adequate to fulfill its research and market
introduction activities, and achieving a level of revenues adequate to support
the Company's cost structure. Without additional financing, the Company will be
required to reduce the scope of its research and development activities and/or
significantly reduce its expenditures on infrastructure. There can be no
assurance that the Company will be able to obtain such additional financing. The
accompanying financial statements do not include any adjustments to reflect the
possible future effects on the recoverability and classification of assets or
the amounts and classification of liabilities that may result from the possible
inability of the Company to continue as a going concern.

                    Notes to Financial Statements (continued)


1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with a remaining maturity of
less than three months when purchased to be cash equivalents. Cash equivalents
are recorded at cost, which approximates market value.

PROPERTY AND EQUIPMENT

Property and equipment are stated on the basis of cost less accumulated
depreciation and amortization. Depreciation and amortization is calculated using
the straight-line method over the shorter of the estimated useful lives of the
assets (two to seven years) or the term of the applicable lease.

CONCENTRATION OF CREDIT RISK

Financial instruments, which potentially subject the Company to concentrations
of credit risk, consist primarily of cash and cash equivalents. The Company
limits its exposure to credit loss by placing its cash with high credit quality
financial institutions.

LONG-LIVED ASSETS

In accordance with Statement of Financial Accounting Standards ("SFAS") No. 121,
ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO
BE DISPOSED OF if indicators of impairment exist, the Company assesses the
recoverability of the affected long-lived assets by determining whether the
carrying value of such assets can be recovered through the undiscounted future
operating cash flows. If impairment is indicated, the Company measures the
amount of such impairment by comparing the carrying value of the asset to the
present value of the expected future cash flows associated with the use of the
asset. While the Company's current and historical operating and cash flow losses
are indicators of impairment, the Company believes the future cash flows to be
received from the long-lived assets will exceed the assets' carrying value, and
accordingly, the Company has not recognized any impairment losses through
December 31, 2000.


                                       11

                    Notes to Financial Statements (continued)


1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

INCOME TAXES

In accordance with SFAS No. 109, ACCOUNTING FOR INCOME TAXES, a deferred tax
asset or liability is determined based on the difference between the financial
statement and tax basis of assets and liabilities as measured by the enacted tax
rates, which will be in effect when these differences reverse. The Company
provides a valuation allowance against net deferred tax assets unless, based
upon the available evidence, it is more likely than not that the deferred tax
assets will be realized.

RESEARCH AND DEVELOPMENT

Research and development costs are expensed as incurred.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

COMPREHENSIVE INCOME (LOSS)

SFAS No. 130, REPORTING COMPREHENSIVE INCOME, requires that all components of
comprehensive income, including net income, be reported in the financial
statements in the period in which they are recognized. Comprehensive income is
defined as the change in equity during a period from transactions and other
events and circumstances from non-owner sources. Net income (loss) and other
comprehensive income (loss), including foreign currency translation adjustments,
and unrealized gains and losses on investments, shall be reported, net of their
related tax effect, to arrive at comprehensive income (loss). Comprehensive loss
for the years ended December 31, 2000 and 1999, and for the period December 1,
1994 (inception) to December 31, 2000, did not differ from reported net loss.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

STOCK-BASED COMPENSATION

The Company has elected to follow Accounting Principles Board Opinion No. 25,
ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES ("APB 25") and related Interpretations
in accounting for its employee stock options. Under APB 25, when the purchase
price of restricted stock or the exercise price of the Company's employee stock
options equals or exceeds the fair value of the underlying stock on the date of
issuance or grant, no compensation expense is recognized.

Options or stock awards issued to non-employees are recorded at their fair value
as determined in accordance with SFAS No. 123, ACCOUNTING FOR STOCK BASED
COMPENSATION and EITF 96-18, ACCOUNTING FOR EQUITY INSTRUMENTS THAT ARE ISSUED
TO OTHER THAN EMPLOYEES FOR ACQUIRING, OR IN CONJUNCTION WITH SELLING GOODS AND
SERVICES and recognized over the related service period.

In March 2000, the Financial Accounting Standards Board issued FASB
Interpretation No. 44, ACCOUNTING FOR CERTAIN TRANSACTIONS INVOLVING STOCK
COMPENSATION, an interpretation of APB 25 ("FIN 44" or the "Interpretation").
The Interpretation, which has been adopted prospectively as of July 1, 2000,
requires that stock options that have been modified to reduce the exercise price
be accounted for as variable. Management believes the Company's accounting for
its stock options is in compliance with the guidelines provided in FIN 44, and
therefore, the adoption of FIN 44 will not significantly affect the Company's
results of operations.

RECENTLY ISSUED ACCOUNTING STANDARDS

Effective January 1, 2001, the Company will adopt SFAS No. 133, ACCOUNTING FOR
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. The adoption of SFAS No. 133 is
not anticipated to have an impact on the Company's results of operations or
financial condition as the Company believes it does not engage in activities
covered by the statement.

3.  COMMITMENTS

The Company leases its office and research facilities under a noncancelable
operating lease which expires in 2004. The lease requires the Company to pay for
all maintenance, insurance and property taxes.

The Company leases a significant portion of its equipment under capital lease
agreements. At December 31, 2000 and 1999, assets purchased under these capital
lease agreements totaled approximately $782,989 with accumulated amortization
totaling approximately $259,105 and $189,433, respectively.

Future minimum payments are as follows at December 31, 2000:

4.  STOCKHOLDERS' EQUITY

PREFERRED STOCK

The Series A, B, C and D preferred stock are convertible at the option of the
holder into the number of shares of common stock which results from dividing the
original issuance price for such series of preferred stock by 83.33% of the
conversion price for such series of preferred stock that is in effect at the
time of conversion. The initial conversion price for a series of preferred stock
shall be the original issuance price for such series, subject to certain
adjustments. In addition, the preferred stock will automatically convert into
common shares upon the closing of an underwritten public offering of equity
securities which results in gross proceeds of at least $20,00,000, at a per
share price of not less than $10.00. The holder of each share of preferred stock
is entitled to one vote for each share of common stock into which it would
convert.

Holders of the preferred shares have parity with holders of common stock on an
as-if converted basis for all dividends declared by the Board of Directors. To
date, the Company has not declared any dividends.

In the event of liquidation, the preferred stockholders receive a liquidation
preference equal to the original issuance price plus declared but unpaid
dividends. The liquidation preference has priority over all distributions to
common stockholders. After payment of the liquidation preference, all remaining
assets from liquidation are to be paid to the preferred stockholders and common
stockholders according to the number of shares held.

WARRANTS

In July 1997, in connection with a capital lease agreement, the Company issued
warrants to purchase 34,286 shares of common stock at an exercise price of $1.75
per share. The warrants expire on August 25, 2004. As of December 31, 2000, no
warrants had been exercised.

4.  STOCKHOLDERS' EQUITY (CONTINUED)

COMMON STOCK

The majority of the outstanding shares of common stock have been issued to the
founders, directors, employees, and consultants to the Company. In connection
with certain stock purchase agreements, the Company has the option to
repurchase, at the original issuance price, the unvested shares in the event of
termination of employment or engagement. Shares under these agreements vest over
periods up to four years. At December 31, 2000, 360,417 shares were subject to
repurchase by the Company.

STOCK OPTIONS

Various employees, directors, and consultants have been granted options to
purchase common shares under equity incentive plans adopted in 1995 and 1997.
These plans provide for the grant of up to 2,507,944 incentive and nonstatutory
stock options. Options granted under these plans generally expire no later than
10 years from the date of grant (five years for a 10% stockholder). Options
granted to each participant who is not an officer, director or consultant of the
Company generally vest and become fully exercisable over a period of five years.
The exercise price of incentive stock options must be equal to at least the fair
market value of the Company's common stock on the date of grant, and the
exercise price of non-statutory stock options may be no less than 85% of the
fair value of the Company's common stock on the date of grant. The exercise
price of any option granted to a 10% stockholder may be no less than 110% of the
fair value of the Company's common stock on the date of grant.

The Company has elected to follow APB 25 and related Interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS No. 123 requires use
of option valuation models which the Company believes were not developed for use
in valuing employee stock options. Under APB 25, because the exercise price of
the Company's employee stock options equals the market price of the underlying
stock on the date of grant, no compensation expense is recognized.

Pro forma net loss information is required to be disclosed by SFAS No. 123, and
has been determined as if the Company has accounted for its employee stock
options under the fair value method prescribed in that statement. The fair value
of these options was estimated

at the date of grant using the minimum value pricing model with the following
weighted average assumptions for 2000 and 1999: risk-free interest rate of 6%;
dividend yield of 0%; and a weighted-average life of the option of four years.
Pro forma net loss under SFAS No. 123 for 2000 and 1999 was $3,077,633 and
$5,730,450 respectively.

The minimal value pricing model is similar to Black-Scholes option valuation
model, which was developed for use in estimating the fair value of traded
options which have no vesting restrictions and are fully transferable, except
that it excludes the factor for volatility. In addition, option valuation models
require the input of highly subjective assumptions. Because the Company's
employee stock options have characteristics significantly different from those
of traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in management's opinion, the existing
models do not necessarily provide a reliable single measure of the fair value of
its employee stock options.

The weighted average grant-date fair value of options granted during 2000 and
1999 was $0.50 and $0.38 per share, respectively. At December 31, 2000,
1,372,914 stock options to purchase common stock were vested and exercisable and
at December 31, 2000, 537,967 shares remain available for future grant under the
1997 Plan.

December 1, 1994 (inception) to December 31, 2000 is as follows:

5.  LICENSE AND RESEARCH AGREEMENTS

In June 1999, the Company entered into a 21 year exclusive worldwide license
agreement with the Regents of the University of California for the use, sale,
offer to sell, make, export or import certain of the University's Peptide
Patents. Pursuant to the terms of the agreement, the Company agreed to pay a
license maintenance fee of $15,000 for each year that the Company is not selling
a commercially licensed product. The Company will reimburse the University for
all patent costs, and shall also pay an annual fee for

patent costs up to $5,000. The agreement also provides for the Company to pay
royalties of 1.5% of net sales. Under this agreement the Company has made
payments totaling approximately $174,514 through December 31, 2000. In
conjunction with this agreement the Company is expected to fund research on
Peptides in an amount not less than $500,000 per year until the first commercial
sale of a licensed product. The Company has the right to terminate this
agreement without cause upon a 90-day written notice to the University.

Since 1995, the Company has entered into various research agreements with the
Regents of the University of California ("the University"), with the most recent
agreement to expire on June 30, 2001. Pursuant to the terms of the agreement,
the Company agreed to fund research of $500,000 through June 30, 2001, for
specified research performed by the University. Total amounts paid under this
agreement for the years ended December 31, 2000 and 1999, and for the period
from December 1, 1994 (inception) to December 31, 2000, are $750,015, $912,416
and $4,418,934, respectively.

CLINICAL RESEARCH AGREEMENT

In September 1998, the Company entered into a $2,700,000 clinical research
agreement with Neuroclinical Trials Center, Inc. ("NTC"). Pursuant to the terms
of the agreement NTC will perform clinical trials management services in support
of clinical investigation of the Company's potential products. For the year
ended December 31, 1999, and for the period from December 1, 1994 (inception) to
December 31, 2000, total amounts paid under this agreement are $1,901,367 and
$2,836,806, respectively. No amounts were paid under the agreement for the year
ended December 31, 2000.

6.  INCOME TAXES

At December 31, 2000, the Company had federal and California tax net operating
loss carryforwards of approximately $19,417,000 and $5,102,000 respectively. The
difference between the tax loss carryforwards for federal and California
purposes is primarily attributable to the capitalization of research and
development expenses for California. The federal tax loss carryforwards will
begin expiring in 2009, unless previously utilized. The remaining tax loss
carryforward will begin expiring in 2001 unless previously utilized. The Company
also has federal and California research and development tax

credit carryforwards totaling $679,000 and $502,000 which will expire beginning
in 2005 unless previously utilized.

Pursuant to Internal Revenue Code Sections 382 and 383, use of the Company's net
operating loss and tax credit carryforwards will be limited as a result of
certain cumulative changes in the Company's stock ownership, which occurred
during 1998. However, the Company believes that the limitation will not have a
material impact on the utilization of the carryforwards.

Significant components of the Company's deferred tax assets as of December 31,
2000 and 1999 are shown below. A valuation allowance of $8,720,000, of which
$7,686,000 relates to 1999, has been recognized to offset the deferred tax
assets as realization of such assets is uncertain.

7.  RELATED PARTY TRANSACTIONS

Since 1995, the Company has entered into various consulting agreements with its
founder whereby the Company pays a monthly consulting fee ranging from $2,000 to
$4,000 and travel expenses in exchange for services performed. For the years
ended December 31, 2000 and 1999, and the period from December 1, 1994
(inception) to December 31, 2000, the Company recorded expenses related to these
agreements of approximately $40,000, $48,774 and $198,774, respectively.

                     NOTES TO UNAUDITED FINANCIAL STATEMENTS

Note 1.           BASIS OF PRESENTATION

         In the opinion of management, the condensed financial statements
include all adjustments, consisting of only normal recurring accruals,
considered necessary for a fair presentation. Operating results for interim
periods are not necessarily indicative of the results that may be expected for
the full year. The accounting policies continue unchanged from December 31,
2000. For further information, refer to the Financial Statements and footnotes
thereto included elsewhere in this Current Report on Form 8-K. Cash flow
statements have not been provided because the cash used in operations is not
significantly different from the net loss.

Note 2.           ACQUISITION

         On March 19, 2001, Bio-Technology General Corp. ("BTG") acquired Myelos
Corporation. Under the terms of the acquisition agreement, BTG paid Myelos
shareholders $35 million in a combination of cash and stock ($14 million in cash
and $21 million through the issuance of 2,344,657 shares of BTG common stock
(based on a value of $8.9564, representing the average closing price of BTG's
common stock for the 20 trading day period ending one day prior to the February
21, 2001 date the acquisition agreement was executed)). BTG will make additional
payments to the Myelos shareholders upon the occurrence of certain events.

Note 3.           SEVERANCE PAYMENTS

         In connection with the acquisition of Myelos by BTG, Myelos
terminated the employment of its President and Chief Executive Officer and
its Vice President-Business Development. In connection with this termination
of employment Myelos made severance payments aggregating $244,000 to these
individuals. These payments are included in general and administrative
expense for the periods from January 1, 2001 to March 19, 2001 and from
December 1, 1994 to March 19, 2001.


                                       23



         UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


         On March 19, 2001, BTG acquired Myelos Corporation, a privately-held
biopharmaceutical company focused on the development of novel therapeutics to
treat diseases of the nervous system. Under the terms of the acquisition
agreement, BTG paid Myelos shareholders $35 million in a combination of cash and
stock ($14 million in cash and $21 million through the issuance of 2,344,657
shares of BTG common stock (based on a value of $8.9564, representing the
average closing price of BTG's common stock for the 20 trading day period ending
one day prior to the February 21, 2001 date the acquisition agreement was
executed)). BTG will be obligated to make additional payments to the Myelos
shareholders upon the occurrence of certain events.

         The transaction was treated as a "purchase" for accounting purposes.
The purchase price for accounting purposes is approximately $33,000,000, based
on a value for the approximately 2,344,700 shares of BTG common stock issued in
the acquisition of $8.1172, representing the average closing price of the
Company's common stock for the four day period preceding the date the terms of
the acquisition were agreed to (February 21, 2001). In connection with the
Merger and based on an independent valuation, BTG allocated $45,600,000 to
in-process research and development projects of Myelos, representing the
estimated fair value based on risk-adjusted cash flows of the acquired
technology. At the date of the Merger the technology acquired in the acquisition
was not fully commercially developed and had no alternative future uses.
Accordingly, the value was expensed as of the acquisition date. BTG recorded
negative goodwill of $18,357,000 on its balance sheet, primarily because the
amount written off as in-process research and development acquired exceeded the
purchase price for accounting purposes. This negative goodwill will be amortized
over its expected useful life of five years.

         The following unaudited pro forma condensed consolidated financial data
gives effect to BTG's acquisition of Myelos Corporation, which has been
accounted for by the purchase method. The pro forma unaudited condensed
consolidated balance sheet as of December 31, 2000 gives effect to BTG's
acquisition of Myelos as if the acquisition had occurred on December 31, 2000,
the last day of our fiscal year. No pro forma balance sheet as of March 31, 2001
is presented as the acquisition of Myelos is reflected in the actual balance
sheet of Bio-Technology General Corp. at March 31, 2001, which is included in
Bio-Technology General Corp's Quarterly Report in Form 10-Q for the quarter
ended March 31, 2001. The pro forma unaudited condensed consolidated statements
of operations give effect to BTG's acquisition of Myelos as if the acquisition
had occurred on January 1, 2000. The pro forma adjustments discussed herein as
based on available information and assumptions that BTG believes are reasonable.

         The following pro forma unaudited condensed consolidated financial data
should be read in conjunction with the historical consolidated financial
statements of BTG and Myelos Corporation. The unaudited pro forma financial data
is presented for informational purposes only and is not necessarily indicative
of BTG's consolidated operating results or consolidated financial position that
would have occurred had the acquisition of Myelos occurred at the dates
indicated, nor is it necessarily indicative of BTG's future operating results or
financial position following the acquisition.

(a)      Adjustment to record the decrease in interest income resulting from the
         payment of $14,000 to the Myelos shareholders in partial payments of
         the purchase price.

(b)      Adjustment to record amortization of negative goodwill of $18,357
         (calculated as of March 19, 2001 (the closing date of the
         acquisition)), which is being amortized over its expected useful life
         of five years. The negative goodwill arose primarily because the amount
         written-off as in-process research and development acquired exceeded
         the purchase price for accounting purposes.

(c)      Adjustment to reflect the tax benefit from Myelos net loss.

(d)      Adjustment to record the adjustment to the income tax provision related
         to pro forma adjustments.

(e)      Represents shares issued to the Myelos shareholders in partial payment
         of the purchase price.

(f)      Adjustment to eliminate the one-time non-cash charge equal to the value
         of technology acquired which was not fully commercially developed and
         had no alternative use at the time of the acquisition.

(g)      Represents shares issued to the Myelos shareholders in partial payment
         of the purchase price which are not included in the historical BTG
         weighted average shares calculation.

(h)      Represents dilutive common stock equivalents included in the
         computation of diluted earnings per share because BTG would have net
         income on a pro forma basis, rather than the net loss it incurred on a
         historical basis.
