                                  (unaudited)

(1)  Financial Statement Presentation

     The unaudited condensed consolidated financial statements and notes thereto
     of Nexell Therapeutics Inc. ("Nexell") and subsidiaries (collectively, the
     "Company") herein have been prepared pursuant to the rules and regulations
     of the Securities and Exchange Commission ("SEC"), and in the opinion of
     management, reflect all adjustments (consisting only of normal recurring
     accruals) necessary to present fairly the results of operations for the
     interim periods presented. Certain information and footnote disclosures
     normally included in financial statements, prepared in accordance with
     generally accepted accounting principles, have been condensed or omitted
     pursuant to such rules and regulations. However, management believes that
     the disclosures are adequate to make the information presented not
     misleading. These condensed consolidated unaudited financial statements and
     notes thereto have been prepared in conformity with the accounting
     principles applied in our 1999 Annual Report on Form 10-K for the year
     ended December 31, 1999 and should be read in conjunction with such Report.
     The results for the interim periods are not necessarily indicative of the
     results for the full fiscal year.

(2)  Principles of Consolidation

     These condensed consolidated financial statements include the accounts of
     Nexell, Nexell of California, Inc. ("NCI") and its subsidiary, VIMRX
     Genomics, Inc. ("VGI"), Innovir Laboratories, Inc. ("Innovir") and its
     subsidiaries. All significant intercompany balances and transactions have
     been eliminated.

(3)  Common Stock Reverse Split

     At the June 14, 2000 annual meeting of stockholders, the stockholders
     approved, and on June 15, 2000 the Company effected, a one for four reverse
     stock split of the Company's outstanding common stock ("Common Stock"). All
     prior period common share and per share information presented in the
     unaudited condensed consolidated financial statements and notes thereto
     have been adjusted to give retroactive effect to the reverse stock split.

                                       6


(4)  Comprehensive Loss

     Comprehensive loss consists of net loss, adjustment to fair value of equity
     investments and foreign currency translation adjustments and is presented
     in the table below. Accumulated other comprehensive loss is included as a
     component of shareholders' equity.

                                    ============       ==========        ===========         ===========


     The cumulative foreign currency translation adjustment included as a
     component of accumulated other comprehensive loss was $36,000 and $5,000 at
     June 30, 2000 and December 31, 1999, respectively. The cumulative
     adjustments for the difference between cost and market value of equity
     securities held as investments included as a component of accumulated other
     comprehensive loss was $3,849,000 and zero at June 30, 2000 and December
     31, 1999, respectively.

     No income tax expense or benefit was allocated to the foreign currency
     translation or equity investment adjustments recorded in 2000 and 1999,
     respectively, due to the Company's significant net operating loss tax
     carryforwards.

(5)  Per Share Information

     Basic net loss per share is computed using the weighted average number of
     shares of common stock outstanding during the period. Diluted net loss per
     share is computed using the weighted average number of shares of common
     stock outstanding and potentially dilutive common shares outstanding during
     the period. Potentially dilutive common shares consist of stock options and
     warrants using the treasury stock method but are excluded if their effect
     is antidilutive.

     Stock options and warrants, excluding Class A performance warrants, to
     purchase 4,394,163, and 4,037,331 shares of Common Stock were outstanding
     at June 30, 2000 and 1999, respectively. Stock options and warrants
     outstanding were not included in the computation of diluted earnings per
     share as the Company incurred losses in all periods presented.

(6)  Restructuring of Sales, Marketing and Distribution Arrangement with Baxter

     As more fully described in the Company's Annual Report on Form 10-K for the
     year ended December 31, 1999, the Company is party to numerous contracts
     with Baxter Healthcare Corporation. Certain of these agreements were
     terminated and/or restructured in 1999. This allowed the Company to assume
     direct control for all sales and distribution of the Company's products.

(7)  Investments

     The Company owns 457,143 shares of the common stock of Epoch
     Pharmaceuticals, Inc., representing approximately 2% ownership at June 30,
     2000. Included in comprehensive income in the second quarter of 2000 is
     the unrealized gain recorded for this investment to fair market value at
     June 30, 2000.

     The Company owns 134,000 shares of the common stock of Ribozyme
     Pharmaceuticals, Inc., representing approximately 1% ownership at June 30,
     2000. These securities are not tradable until August 2000 and, accordingly,
     are valued at cost.

     The above investments are included in "other assets" on the accompanying
     balance sheet and are accounted for under the cost method as neither of the
     investments represent more than 20 percent of the voting stock of the
     investee and the Company does not exercise significant influence over the
     investee's operations or financial policies.

(8)  Distribution and Co-Development Agreement

     On May 9, 2000, the Company announced it had entered into a strategic
     alliance with Takara Shuzo Co., Ltd. ("Takara"), a diversified brewing,
     foods, and biomedical company in Japan. Pursuant to such agreements, Takara
     will become the exclusive distributor of the Company's cell therapy
     products in Japan, Korea, Taiwan and China and the parties will engage in
     development collaborations in gene therapy. In exchange for the
     distribution rights, Takara agreed to pay the Company a nonrefundable fee
     of $2.5 million within 100 days of the agreement's execution. This payment,
     when received, will be recognized as revenue over the five year term of the
     agreement. Under the co-development agreement, the companies will engage in

(9)  Geographic Information

     The Company operates in one industry segment; the development, manufacture,
     marketing and distribution of specialized instruments, biologicals,
     reagents, sterile plastic sets and related products used in ex vivo cell
     research and therapies. Prior to the termination of the Company's
     distribution agreement with Baxter on November 30, 1999, all of the
     Company's sales were made to a domestic entity of Baxter. Substantially all
     of Baxter's end user sales of the Company's products were made
     internationally until regulatory approval for United States distribution
     was received in July 1999. Assets assigned to geographic segments have not
     changed materially since December 31, 1999. Summary comparative operating
     results for the United States and the rest of the world follows:

(10) Recent Accounting Developments

     In December 1999, the United States Securities and Exchange Commission
     issued Staff Accounting Bulletin (SAB) No. 101, "Revenue Recognition in
     Financial Statements", as amended, which for the Company is effective no
     later than the fiscal quarter beginning October 1, 2000. SAB No. 101
     summarizes certain of the staff's views in applying generally accepted
     accounting principles to revenue recognition in financial statements. The
     Company believes that implementation of SAB No. 101 will have no material
     impact on its financial statements.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations.

The following discussion and analysis should be read in conjunction with the
financial statements and notes thereto included elsewhere in this Quarterly
Report on Form 10-Q and with the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 1999.

Three Months Ended June 30, 2000 and 1999

Sales were $4,630,000 for the quarter ended June 30, 2000, an increase of
$3,067,000 or 196% from $1,563,000 for the quarter ended June 30, 1999. In the
prior year, revenues reflected product sales by NCI to its former exclusive
worldwide distributor, Baxter Healthcare Corporation ("Baxter"), and were
impacted by the timing of the distributor's orders. In the current year, as a
result of the 1999 restructuring of the distribution agreement with Baxter, the
Company now sells product directly to multiple end users. Accordingly, timing of
orders less significantly impacts revenues since product sales are distributed
to more than 200 customers rather than a single distributor. The transition from
distribution through Baxter to direct end user sales by the Company required the
recruitment and training of domestic and international sales forces and the
creation of a sales infrastructure, activities which management believes are now
complete. Further, following regulatory approval of the Isolex 300i system in
July 1999, end user sales began in the United States. In addition, pursuant to
an asset transfer agreement, the Company agreed to repurchase inventory,
hardware and related assets previously sold to Baxter for distribution. The
closing for the transfer of assets in the United States and Canada occurred on
June 30, 1999 and in the rest of the world on November 30, 1999. As a result of
this transfer, sales were reduced by approximately $1,387,000 in the three
months ended June 30, 1999 as a result of the return of assets previously sold
to Baxter.

Gross profit was $1,961,000 for the quarter ended June 30, 2000, an increase of
$1,978,000 from the $(17,000) for the quarter ended June 30, 1999. This increase
was due to the impact of the changes in the distribution agreement with Baxter
in the prior year, spreading substantially constant overhead costs over a larger
sales base and changes in sales mix.

Total operating expenses were $10,472,000 for the three months ended June 30,
2000, an increase of $1,565,000 or 18% over the quarter ended June 30, 1999.
This increase was the result of an increase in sales, marketing and distribution
expenses of $1,412,000, an increase of $697,000 in general and administrative
expenses and an increase of $94,000 in goodwill and intangible assets
amortization offset by a decrease of $638,000 in research and development
expenses.

Research and development expenses decreased by $638,000 or 14% from $4,464,000
for the three months ended June 30, 1999 to $3,826,000 for the three months
ended June 30, 2000, primarily due to discontinuing all Innovir operations.
General and administrative expenses increased by $697,000 from $2,349,000 in the
second quarter of 1999 to $3,046,000 in the second quarter of 2000. This
resulted principally from increased headcount and related recruitment and
relocation costs as a result of the anticipated growth in revenue following
regulatory approval of the Isolex

                                       10


300i system in July 1999, the need for increased infrastructure as a result of
the revisions to the distribution agreement with Baxter and one-time charges
related to separation agreements with former employees, including certain
officers. Selling, marketing and distribution expenses increased by $1,412,000
or 120% from $1,172,000 in the second quarter of 1999 to $2,584,000 in the
second quarter of 2000 as a result of the restructuring of the distribution
agreement with Baxter. This increase resulted from the Company's assumption of
responsibility for marketing, selling and distribution activities related to its
cell therapy products during late 1999. Baxter had previously performed these
activities. Goodwill and intangible amortization increased by $94,000 or 10% to
$1,016,000 for the quarter ended June 30, 2000 from $922,000 for the quarter
ended June 30, 1999 as a result of acquisitions completed during 1999.

Other income was $257,000 for the quarter ended June 30, 2000, while other
expense of $67,000 was incurred in the quarter ended June 30, 1999, a change of
$324,000. This was primarily the result of a decrease in interest expense from
$542,000 in the three months ended June 30, 1999 to zero for the comparable
period in 2000 and an increase in interest income of $82,000 partially offset by
a decrease of $299,000 in royalty income. The decrease in interest expense and
increase in interest income arose from the repayment of approximately $34
million in convertible debentures from the proceeds of the Company's private
placement financing that was completed in November 1999 and investment of
residual proceeds. The decrease in royalty income resulted from a non-recurring
licensing payment received from Amgen Inc. by Innovir in the second quarter of
1999.

The foregoing resulted in a net loss of $8,254,000 and a net loss applicable to
common stock of $9,841,000 for the quarter ended June 30, 2000. This represented
a decrease in net loss of $737,000 or 8% and a decrease in the net loss
applicable to common stock of $201,000 or 2% from the quarter ended June 30,
1999.

Six Months Ended June 30, 2000 and 1999

Sales were $9,414,000 for the six months ended June 30, 2000, an increase of
$2,337,000 or 33% from $7,077,000 for the six months ended June 30, 1999. This
increase was the result of the changes to the distribution agreement with
Baxter, the completion of the development of an internal sales function,
regulatory approval of the Isolex 300i system and the non-recurring prior year
decrease in sales associated with the repurchase of inventory previously sold to
Baxter which is described in greater detail above.

Gross profit was $4,202,000 for the six months ended June 30, 2000, an increase
of $1,863,000 from the $2,339,000 for the six months ended June 30, 1999. This
increase was due to the impact of the changes in the distribution agreement in
the prior year and spreading substantially constant overhead costs over a larger
sales base and changes in sales mix.

Total operating expenses were $20,613,000 for the six months ended June 30,
2000, an increase of $3,488,000 or 20% over the six months ended June 30, 1999.
This increase was the result of several factors. General and administrative
expenses increased by $1,147,000 or 25% from $4,510,000 in 1999 to $5,657,000 in
2000. This was largely due to increased headcount and

                                       11


related recruitment and relocation costs as a result of the anticipated growth
in revenue following regulatory approval of the Isolex 300i system in July 1999,
the need for increased infrastructure as a result of the revisions to the
distribution agreement with Baxter and one-time charges related to separation
agreements with former employees, including certain officers. Selling and
marketing expenses increased by $2,852,000 or 134% from $2,123,000 in the first
six months of 1999 to $4,975,000 in the first six months of 2000. This was the
result of the restructuring of the distribution agreement with Baxter and the
ramp up in sales and marketing activities associated with regulatory approval of
the Isolex system. The changes in the agreement with Baxter resulted in the
Company's assumption of responsibility for marketing, selling and distribution
activities related to its cell therapy products. Baxter had previously performed
these activities. Goodwill and intangible amortization increased by $286,000 or
16% to $2,033,000 for the six months ended June 30, 2000 from $1,747,000 for the
six months ended June 30, 1999 as a result of acquisitions completed during
1999. The expense increases discussed above were partially offset by a $504,000
decrease in restructuring costs related to the relocation of the Company's
corporate headquarters in the previous year while no such costs were incurred in
the current year, and by a decrease in research and development expenses of
$293,000 or 4% from $8,241,000 in the first six months of 1999 to $7,948,000 in
the first six months of 2000.

Other income was $426,000 for the six months ended June 30, 2000, while other
expense of $324,000 was incurred in the six months ended June 30, 1999, a change
of $750,000. This was primarily the result of a decrease in interest expense
from $1,030,000 in the six months ended June 30, 1999 to zero for the comparable
period in 2000 offset by a decrease of $224,000 in royalty income. The decrease
in interest expense arose from the repayment of approximately $34 million in
convertible debentures from the proceeds of the Company's private placement
financing that was completed in November 1999. The decrease in royalty income
resulted from a non-recurring licensing payment received from Amgen Inc. by
Innovir in the second quarter of 1999.

The foregoing resulted in a net loss of $15,985,000 and a net loss applicable to
common stock of $19,147,000 for the six months ended June 30, 2000. This
represented an increase in net loss of $875,000 or 6% and an increase in the net
loss applicable to common stock of $1,946,000 or 11% from the six months ended
June 30, 1999.

Liquidity and Capital Resources

The Company had $18,002,000 in cash and cash equivalents as of June 30, 2000 as
compared to $28,695,000 as of December 31, 1999, and working capital of
$17,207,000 at June 30, 2000 as compared to $28,031,000 at December 31, 1999.
The $10,693,000 decrease in cash and cash equivalents resulted principally from
cash used in the operations of the Company of $13,127,000, and purchases of
equipment totaling $712,000. These were partially offset by cash proceeds of
$3,083,000 from the exercise of stock options and warrants and $77,000 from the
sale of equipment. The decrease in working capital of $10,824,000 resulted
principally from the decrease in cash and cash equivalents.

                                       12


Cash used in operating activities in the first six months of 2000 of $13,127,000
represented an increase of $3,255,000 or 33% from the cash use of $9,872,000 for
the six months ended June 30, 1999.  The increase is due principally to an
increase in the net loss of $875,000, an increase of $494,000 in non cash
depreciation and amortization, an increase in trade receivables of $1,045,000
due to changes in the agreements with Baxter and an increase in European
receivables and an increase in cash used for other current assets and other
assets of $1,499,000 related to value added tax deposits necessary in Europe and
other deposits and miscellaneous receivables. Remaining changes in current
assets and liabilities largely offset.

Cash dividends are payable semi-annually in May and November on the Series B
Preferred Stock at the rate of 3% of the liquidation preference and will be
approximately $1,900,000 per year.

At this time, the Company does not have any specific plans to acquire any
company.  The Company, in the ordinary course of business, routinely explores
possible business transactions that may lead to an acquisition.  In general, in
order to conserve cash the Company's preference is to use its stock as
consideration for any potential acquisition.

The Company expects to incur substantial expenditures in the foreseeable future
for the research and development and commercialization of its proposed products.
Based on current projections, which are subject to change, the Company's
management believes that the current balance of cash and cash equivalents is
sufficient to fund its operations through at least fiscal 2000.  Thereafter, the
Company will require additional funds, which it may seek to raise through public
or private equity or debt financings, collaborative or other arrangements with
corporate sources, or through other sources of financing. There can be no
assurance that such additional funds will be available to the Company on terms
favorable to the Company, or at all.

On May 9, 2000, the Company announced it had entered into a strategic alliance
with Takara Shuzo Co., Ltd. ("Takara"), a diversified brewing, foods, and
biomedical company in Japan. Pursuant to such agreements, Takara will become the
exclusive distributor of the Company's cell therapy products in Japan, Korea,
Taiwan and China and the parties will engage in development collaborations in
gene therapy. In exchange for the distribution rights, Takara agreed to pay the
Company a nonrefundable fee of $2.5 million within 100 days of the agreement's
execution. This payment, when received, will be recognized as revenue over the
five year term of the agreement. Under the co-development agreement, the
companies will engage in co-development efforts to develop a product in the
field of ex-vivo genetic transduction combining the Company's technology and
Takara's product.

Year 2000 Issues

The Company has experienced no material disruption in the operation of its
business as a result of the transition from 1999 to 2000. No future costs are
anticipated with respect to Year 2000 compliance.  The Company's product lines
all operate independently of the date or time of day; thus, the transition to
the Year 2000 has not affected their operation.  The Company continues to
monitor its IT and non-IT systems, as well as its vendors, suppliers, and
partners to ensure continued Year 2000 compliance.  Although the Company will
take all practical measures to prevent future problems related with the Year
2000 issue, such problems and failures may occur which could seriously affect
the Company's operation.  Because of the unprecedented nature of such problems,
the extent of the effect on the Company's operations, if any, cannot be
determined.

Disclosure Regarding Forward Looking Statements

This Report on Form 10-Q contains certain statements that are "Forward Looking
Statements" within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended.
Those statements include, among other things, the discussions of the Company's
business strategy and expectations contained in "Item 2 - Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                                       13


Although the Company believes that the expectations reflected in Forward Looking
Statements are reasonable, management can give no assurance that such
expectations will prove to have been correct.  Generally, these statements
relate to business plans or strategies, projected or anticipated benefits or
other consequences of such plans or strategies, or projections involving
anticipated revenues, expenses, earnings, levels of capital expenditures,
liquidity or indebtedness or other aspects of operating results or financial
position.  All phases of the operations of the Company are subject to a number
of uncertainties, risks and other influences (including the timely commencement
and success of the Company's clinical trials and other research endeavors,
delays in receiving FDA or other regulatory approvals, the development of
competing therapies and/or technologies, the terms of any future strategic
alliances,  the possible need for additional capital, and  the volatility in the
market price for the Company's securities) many of which are outside the control
of the Company and any one of which, or a combination of which, could materially
affect the results of the Company's operations and whether the Forward Looking
Statements made by the Company ultimately prove to be accurate.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

In the normal course of business, operations of the Company are exposed to risks
associated with fluctuations in interest rates and foreign currency exchange
rates.

Interest Rate Risk

The Company maintains excess cash in a mutual fund, the "BlackRock Low Duration
Bond Portfolio" (the "fund"), which invests in asset backed securities, bonds
and various other commercial obligations.  The fund may, from time to time, use
certain derivatives in its investment strategy.

Two of the main risks disclosed by the fund are interest rate risk and credit
risk.  Typically, when interest rates rise, there is a corresponding decline in
the market value of bonds such as those held by the fund.  Credit risk refers to
the possibility that the issuer of the bond will not be able to make principal
and interest payments.  The Company addresses these risks by actively monitoring
the fund's performance and investment holdings.  The Company does not enter into
financial instruments for trading or speculative purposes.

The Company's interest income is most sensitive to fluctuations in the general
level of U.S. interest rates.  In this regard, changes in the U.S. interest
rates affect the interest earned on the Company's cash as well as the value of
the mutual fund in which excess cash is invested.

The Company's exposure to market risk for changes in interest rates relates
primarily to the Company's investment of excess cash in a mutual fund, which
invests in asset backed securities, bonds and various other commercial
obligations.  The fund may, from time to time, use certain derivatives in its
investment strategy.  The fund's portfolio managers make all investment
decisions and the Company has no control over such investment decisions or the
fund's use of derivatives.

                                       14


Foreign Currency Risk

Changes in foreign exchange rates, and in particular a strengthening of the U.S.
dollar, may negatively affect the Company's consolidated sales and gross margins
as expressed in U.S. dollars.  To date, the Company has not entered into any
foreign exchange contracts to hedge its exposure to foreign exchange rate
fluctuations.  However, as its international operations grow, the Company may
enter into foreign exchange contracts to manage its foreign exchange risk.

Part II - OTHER INFORMATION

Item 1.  Legal Proceedings.

On March 2, 2000, the Company filed suit in the U.S. District Court in Delaware
(civil case number 00-141) against Miltenyi Biotec GmbH of Germany and its
related U.S. companies, Miltenyi Biotec, Inc. and AmCell Corporation. The suit
charges Miltenyi with patent infringement, breach of contract and deceptive
trade practices. Becton, Dickinson & Company and The Johns Hopkins University,
both of whom have proprietary rights associated with the Company's technology,
have joined with the Company in the suit. The Company is seeking damages and
injunctive relief. The parties are currently engaged in pretrial discovery and a
trial is currently scheduled for May 14, 2001.  Miltenyi Biotec GmbH of Germany
is contesting whether jurisdiction is proper in the Delaware Court.

Item 2.  Changes in Securities and Use of Proceeds.

On June 15, 2000, the Company effected a one for four reverse stock split of its
Common Stock. See Note (3) to the Condensed Consolidated Financial Statements.
As a result of the reverse stock split, the exercise price of the Company's
publicly traded warrants (Nasdaq:NEXLW) to purchase one share of Common Stock
changed from $1.35 per share to $5.40 per share and the warrants are now
exercisable for one-fourth the number of shares of Common Stock for which they
had been exercisable prior to the reverse stock split.  There were also
corresponding adjustments to the Company's privately placed derivative
securities.

Item 3.  Defaults Upon Senior Securities.

Not applicable.

Item 4.  Submission of Matters to a Vote of Security Holders.

The 2000 annual meeting of stockholders of the Company was held on June 14,
2000. The following matters were voted upon at the meeting: (i) the election as
