ITEM 5.  OTHER EVENTS.

Strategic Partnership With Abbott Laboratories

On July 23, 1999, NaPro entered into Development, License and Supply Agreement
(the "Development Agreement") with Abbott Laboratories ("Abbott"). The
Development Agreement is a 20-year collaborative agreement with Abbott to
develop and commercialize one or more formulations of paclitaxel for the
treatment of a variety of cancer indications. The exclusive agreement covers the
United States and Canada.

NaPro will be responsible for supply of bulk drug and will jointly conduct
clinical trials with Abbott. Abbott will be responsible for the finishing,
regulatory filings, marketing and sale of the finished drug product. NaPro has
licensed to Abbott its paclitaxel-related patents. Most primary decisions
related to the development program will be made by a joint NaPro-Abbott
Development Committee. Under the Development Agreement, NaPro and Abbott have
begun recruiting sites and investigators for the next phase of pivotal studies.
Clinical studies to be pursued by NaPro and Abbott will investigate several
different cancers in a variety of populations.

NaPro has and will receive funding from Abbott in the form of development and
marketing milestone payments, a secured loan and an equity investment. On July
26, 1999, NaPro received $5 million, consisting of an initial $1 million fee, $2
million from the purchase by Abbott of NaPro common stock at $5.00 per share,
and a $2 million draw-down on a secured loan. In addition to payments at
closing, NaPro expects to receive up to $7 million in the remainder of 1999
consisting of another $1 million in fees, an additional $2 million equity
investment (both of which are subject to certain operating milestones) and
additional advances under the loan commitment of up to $4 million.

Contingent upon NaPro's successful achievement of all development milestones and
including all payments expected in 1999, NaPro could receive up to $48 million
consisting of $38 million in development fees and $10 million for the purchase
of 2 million shares of NaPro common stock. In addition, NaPro also will have
access to up to $20 million under a secured loan arrangement with Abbott. The
loan bears a primary interest rate of 6.5% and is due in full on the earlier of:
(i) the second anniversary of the first sale of finished product by Abbott to a
wholesaler or end-user customer following approval of finished product by the
U.S. Food and Drug Administration; (ii) the termination of the Development
Agreement; or (iii) January 1, 2007. The loan is limited to a borrowing base of
collateralized assets, recomputed monthly.

Contingent upon achieving certain commercial sales thresholds over several
years, NaPro may receive additional milestone payments from Abbott of up to $57
million. No assurance can be given that regulatory approval or sales thresholds
will be achieved.

Under terms of the Agreement, Abbott will purchase bulk drug from NaPro. Once
the paclitaxel product is approved and commercialized, Abbott will pay a
percentage of its net paclitaxel sales to NaPro, less Abbott's payments to NaPro
for purchase of bulk drug.

The Development Agreement and the stock purchase and loan agreements with Abbott
are filed as exhibits to this Report.

           Revised Management's Discussion and Analysis of Financial
                      Condition and Results of Operations

On or about October 5, 1999 NaPro will mail its annual report to its
stockholders. In connection with the Development Agreement and the other
agreements with Abbott, NaPro believed it appropriate to revise the disclosure
regarding NaPro's financial condition and results of operations from that
reported previously in its Annual Report on Form 10-K. Accordingly, we include
the following revised disclosure as it appears in NaPro's annual report to
stockholders.

         Management's Discussion and Analysis of Financial Condition and
                              Results of Operations

The following discussion and analysis provides information which management
believes is relevant to an assessment and understanding of the results of
operations of NaPro. This discussion should be read in conjunction with the
Financial Statements and Notes included elsewhere in this Report [NaPro's 1998
Annual Report to stockholders]. It has been updated from that contained in its
Annual Report on Form 10-K to include reference to NaPro's transaction with
Abbott, to reflect implications of such transaction and to update certain other
matters. Special Note: Certain statements set forth below constitute
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995 (the "Reform Act"). See "Special Note Regarding
Forward Looking Statements".

General

NaPro is a natural product pharmaceutical company which is focusing primarily on
the development, manufacture and commercialization of paclitaxel, a
naturally-occurring anticancer agent found in certain species of yew (Taxus)
trees.

NaPro has devoted its efforts primarily to the development and implementation of
its proprietary extraction, isolation and purification (EIP(TM)) technology and
the development of its proprietary semi-synthetic method for producing NaPro
paclitaxel. To advance the development and commercialization of NaPro
paclitaxel, NaPro entered into 20-year, exclusive agreements with F.H. Faulding
& Co., Ltd. ("Faulding") and IVAX Corporation (including its subsidiaries,
"IVAX") for the clinical development, sales, marketing and distribution of NaPro
paclitaxel. NaPro and IVAX entered into an agreement on March 20, 1998, (the
"Termination Agreement") terminating their development and marketing
relationship.

On July 23, 1999 NaPro entered into a 20-year collaborative agreement (the
"Abbott Agreement") with Abbott Laboratories ("Abbott") to develop and
commercialize one or more formulations of paclitaxel for the treatment of a
variety of cancer indications. The exclusive agreement covers the United States
and Canada.

NaPro will be responsible for supply of bulk drug and will jointly conduct
clinical trials with Abbott. Abbott will be responsible for the finishing,
regulatory filings, marketing and sale of the finished drug product. NaPro has
licensed to Abbott its paclitaxel-related patents. Most primary decisions

million from the purchase by Abbott of NaPro common stock at $5.00 per share,
and a $2 million drawdown on a secured loan. In addition to payments at closing,
NaPro may receive up to $7 million in the remainder of 1999 consisting of
another $1 million in fees, an additional $2 million equity investment (both of
which are subject to certain operating milestones) and additional advances under
the loan commitment of up to $4 million.

Contingent upon NaPro's successful achievement of all development milestones and
including all payments expected in 1999, NaPro could receive up to $48 million
consisting of $38 million in development fees and $10 million for the purchase
of 2 million shares of NaPro common stock. In addition, NaPro also will have
access to up to $20 million under a secured loan arrangement with Abbott. The

(i) the second anniversary of the first sale of finished product by Abbott to a
wholesaler or end-user customer following approval of finished product by the
U.S. Food and Drug Administration ("FDA"); (ii) the termination of the Abbott
Agreement; or (iii) January 1, 2007. The loan is limited to a borrowing base of
collateralized assets, recomputed monthly.

Contingent upon achieving certain commercial sales thresholds over several
years, NaPro may receive additional milestone payments from Abbott of up to $57
million dollars. No assurance can be given that regulatory approval or sales
thresholds will be achieved.

Under terms of the Abbott Agreement, Abbott will purchase bulk drug from NaPro.
Once the paclitaxel product is approved and commercialized, Abbott will pay a
percentage of its net paclitaxel sales to NaPro, less Abbott's payments to NaPro
for purchase of bulk drug.

NaPro is in discussions with a number of international pharmaceutical companies
to assist NaPro in developing and marketing NaPro paclitaxel in various parts of
the world. NaPro is currently dependent for revenue exclusively on sales of
NaPro paclitaxel and on royalties and payments related to licensed technology.

NaPro has initiated and is co-managing with Abbott clinical studies exploring
the use of its patented formulation of paclitaxel using its patented method of
administration. NaPro anticipates that information gained in such studies will
be useful in the filing of a New Drug Application with the FDA for NaPro
paclitaxel. The cost of such studies is increasing and will be significant.

Through June 30, 1999, NaPro's production of paclitaxel was limited primarily to
research and pilot-scale production, and much of NaPro's product sales and
production were for use in clinical trials and for research and development
purposes. Accordingly, NaPro has generated only limited revenue from such
activities and has incurred significant losses, including operating losses of
approximately $13.4 million, $13.8 million and $7.1 million for the years ended
December 31, 1998, 1997 and 1996, respectively. For the six months ended June
30, 1999, NaPro recorded an operating loss of approximately $4.2 million. The
accumulated deficit at June 30, 1999 was $47.1 million. NaPro expects that it
will continue to have a high level of operating expense and will be required to
make significant up-front expenditures in connection with its clinical trials,
biomass procurement, product development, and other research and development
activities. NaPro anticipates that losses will continue until such time, if
ever, as NaPro is able to generate sufficient revenue to support its operations.

NaPro believes that its ability to generate revenue depends primarily on its
ability to obtain regulatory approval in the U.S. or another major market for
the commercial sale of NaPro paclitaxel, on NaPro's ability to obtain partners,
on NaPro's ability to obtain regulatory approval for its manufacturing
facilities and on NaPro's ability to construct manufacturing facilities that
produce quantities of NaPro paclitaxel sufficient to supply NaPro's strategic
partners' requirements for commercial sales. Moreover, NaPro's future growth and
profitability will depend on the success of its strategic partners in fostering
acceptance in the oncological market for NaPro paclitaxel as a preferred dosing
regimen of taxane chemotherapy to be used alone or in combination with other
chemotherapeutic agents.

In January 1995, Faulding received approval to market NaPro paclitaxel
commercially in Australia under the trade name ANZATAX(TM). Faulding's
effectiveness in marketing NaPro paclitaxel in Australia and other markets will
continue to have a significant affect on NaPro's operations.

In February 1997, Bristol-Myers Squibb Company ("Bristol") submitted a
Supplemental New Drug Application with orphan drug designation for paclitaxel
for the treatment of Kaposi's sarcoma ("KS") before the filing by IVAX of a New
Drug Application ("NDA") for the same indication. The Bristol application was
approved by the FDA in August 1997. Under the Orphan Drug Act of 1983, this
approval resulted in IVAX/NaPro being denied marketing approval for the KS
indication for seven years.

In February 1998, due to the delay in receiving marketing approval for NaPro
paclitaxel, NaPro underwent a restructuring to decrease overall cost. As part of
the restructuring NaPro temporarily closed its British Columbia manufacturing
facility and suspended construction of its commercial scale manufacturing
facility in Boulder, Colorado. Completion of the Boulder facility will require
additional financing, which NaPro intends to seek at such time, if ever, as
NaPro anticipates sufficient product demand to warrant completion of the
facility.

In March 1998, NaPro and IVAX entered into the Termination Agreement. The
termination of the IVAX Agreement leaves NaPro free to seek regulatory approvals
and market NaPro paclitaxel under the Abbott Agreement and to seek an
international partner or partners with


                                                         5

which to pursue regulatory approvals and marketing of NaPro paclitaxel outside
the territory contractually allocated to Faulding. There can be no assurance
that NaPro will be able to secure such approvals or form new long-term
relationships for the approval, marketing, and distribution of NaPro paclitaxel
in these areas, or that NaPro, Abbott or international partners, if found, will
be able to effectively market NaPro paclitaxel.

Results of Operations

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

Sales. 1998 sales were $5 million, up $1.2 million from 1997. Sales to IVAX for
1998 were $2.7 million, up $400,000 from 1997. Sales to IVAX, as a result of the
Termination Agreement, are expected to end in the third 1999 quarter. Future
product sales in territory outside that covered by NaPro's agreement with
Faulding (the "Faulding Agreement") may be dependent upon the ability of NaPro
to secure new agreements supporting the development and marketing of NaPro's
paclitaxel within that territory. Sales other than to IVAX for 1998 were $2.2
million, up $700,000 from 1997. The increase was due primarily to the timing of
product shipments and to inventory fluctuations of NaPro's strategic partners.
Sales may vary significantly depending on a number of factors, including the
timing and size of any clinical trials, NaPro's obtaining one or more partners
to replace IVAX, changes in demand, the level of inventory carried and changes
in approved markets. This variability will continue until stable commercial
demand has been established for the product in one of NaPro's principal markets.

Research, Development and Cost of Products Sold. Research and development
expense and cost of products sold for 1998 was $10 million, down by $1.8 million
from 1997. The decrease resulted primarily from the benefits of the February
1998 restructuring, a decrease in the level of process development and research,
and lower production cost. NaPro's production process is not distinct from its
research and development processes. Accordingly, the cost of products sold is
included within NaPro's research and development expense.

General and Administrative Expense. General and administrative expense for 1998
was $6.5 million, up $500,000 from 1997. The increase is attributable primarily
to increases of $700,000 in legal expense related to European litigation and
$200,000 of consulting expense primarily related to the Termination Agreement,
partially offset by a reduction in recruiting and relocation expense.

Interest Income.  Interest income for 1998 was $600,000,  up $100,000 from 1997.
The  increase is  attributable  to overall  higher  interest  rates  realized on
interest bearing investments. See "Liquidity and Capital Resources".

Interest and Other Expense. Interest and other expense for 1998 was $900,000,
down $1.3 million from 1997. The decrease is primarily attributable to the
non-recurrence of the $1.1 million 1997 expense related to the amortization of
original issue discount on the senior convertible debt, to decreased interest on
the senior convertible debt and to decreased borrowing on equipment financing.
See "Liquidity and Capital Resources".

<PAGE>



Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

Sales. Sales for 1997 were $3.8 million, up $300,000 from 1996. Sales to IVAX
for 1997 were $2.3 million, up $1.7 million from 1996. Sales other than to IVAX
for 1997 were $1.5 million, down $1.3 million from 1996. The increase in total
sales was due primarily to the timing of product shipments and to inventory
fluctuations of NaPro's strategic partners.

Research, Development and Cost of Products Sold. Research and development
expense and cost of products sold for 1997 was $11.8 million, up $4.9 million
from 1996. The increase resulted primarily from expansion of NaPro's development
and research operations in anticipation of possible approval of the NDA filed by
IVAX with the FDA.

General and Administrative Expense. General and administrative expense for 1997
was $5.9 million, an increase of $2.2 million from 1996. The increase is
attributable primarily to increases of $1.1 million in administrative and
support staff, $500,000 in legal cost, $100,000 of occupancy cost, and $400,000
in consulting and outside service expense.

Interest Income.  Interest income for 1997 was $500,000,  a decrease of $200,000
from 1996. The decrease is attributable to smaller free cash balances  available
for investment. See "Liquidity and Capital Resources".

Interest and Other Expense. Interest and other expense for 1997 was $2.2
million, up $1.8 million from 1996. Approximately $1.1 million of the 1997
expense related to the amortization of original issue discount, a non-recurring
charge, on the senior convertible debt. The remainder of the increase is
attributable to interest on the senior convertible debt and increased borrowing
on equipment financing. See "Liquidity and Capital Resources".

Liquidity and Capital Resources

NaPro's capital requirements have been and will continue to be significant. As
of December 31, 1998, NaPro had a working capital balance of $7.1 million. This
compared to a negative working capital balance of ($2.5) million as of December
31, 1997, and reflects the 1997 classification as a current liability of $8.1
million of NaPro's senior convertible notes, which are due in 2000 but which
were redeemable by the holders during the early part of 1998 under certain
conditions. Through December 31, 1998, the funding of NaPro's capital
requirements has been dependent primarily on the net proceeds of public
offerings of its common stock of approximately $21.1 million, on private
placements of its equity securities of approximately $27.8 million, on the
exercise of warrants and options of $5.7 million, on net borrowings of $12
million, and on loans and advances from its stockholders and strategic partners.

NaPro's existing capital and projected 1999 sales are expected to provide
adequate capital to fund its necessary operations and capital expenditures in
1999. Pharmaceutical development is, however, a costly and time consuming
process. NaPro is actively pursuing partners to assist in the development and
marketing of its products, and may seek other forms of long-term financing
should such financing become available on acceptable terms.

In June 1997 NaPro privately placed $10.3 million of senior convertible notes.
The notes mature in June 2000 and bear an interest rate of 5%. Interest on the
notes is payable in cash or in common stock at NaPro's option. The notes are
convertible into common stock at a 10% discount from the lowest market price of
the common stock during specified periods prior to the conversion. If not
converted, upon maturity, the notes will be exchanged for 13.75% 5-year
debentures. In 1998 NaPro issued 2,833,587 shares of common stock in conversion
of $2.9 million principal of the notes, and 296,019 shares of common stock in
payment of $295,000 interest on the notes. In 1998 NaPro redeemed $647,000 in
note principal and paid $53,000 premium and interest in connection with the
redemption. In January 1999 NaPro redeemed $633,000 in note principal and paid
$162,000 premium and interest in connection with the redemption. In the period
after December 31, 1998 through August 6, 1999 NaPro issued 3,597,159 shares of
common stock in conversion of $5 million principal of the notes, and 19,234
shares of common stock in payment of $27,000 interest on the notes.

In December 1997, NaPro privately placed 5,000 shares of Series C Senior
Convertible Preferred Stock (the "C Preferred") for an aggregate issuance price
of $5 million. The C Preferred accrues dividends at 5% per year payable in
common stock or cash at NaPro's option. The C Preferred is convertible into
common stock at a 5% discount from the market price during specified periods
prior to the conversion date. In December 2000, NaPro may force the conversion
of any remaining shares at the conversion price in effect as of December 8,
2000. In 1998 NaPro issued 986,666 shares of common stock in conversion of
$897,000 of the C Preferred and 186,656 shares of common stock in payment of
$183,000 of dividends on the C Preferred. In the period after December 31, 1998
through August 6, 1999 NaPro issued 1,252,558 shares of common stock in
conversion of $2.1 million of the C Preferred and 6,193 shares of common stock
in payment of $10,000 of dividends on the C Preferred.

In January and March, 1998 and January and March, 1999, NaPro entered into
amendments (the "Amendments") with the C Preferred investor and the holders of
the senior convertible notes (together the "Investors"). The parties agreed to:
(a) limit the number of shares which could be converted in the event the stock
price is below $4.00 per share to no more than 450,000 shares per month through
May 14, 1999 and (b) partially remove the ability of the Investors to force
NaPro to redeem any portion of the securities for cash. In the event there is an
unconverted amount of securities on May 15, 1999, such amount will be
convertible under the original terms of the agreements. At any time, NaPro, at
its option, may redeem all or part of the securities, with 5 days written
notice, for amounts ranging from 130% to 140% of the outstanding principal and
accrued dividends and interest.

On August 2, 1999 NaPro redeemed for cash $2 million of shares of its C
Preferred at a cost of $2.8 million including redemption premiums and
outstanding accrued but unpaid dividends. Through that date all but $91,000 of
the shares of the C Preferred outstanding at December 31, 1998 had been either
redeemed or converted into common stock. Through August 2, 1999, all of NaPro's
convertible debt outstanding at December 31, 1998 had been redeemed (in January
1999) or was converted into common stock. Funding for the redemption of NaPro's
convertible debt and the C Preferred was provided by NaPro's current cash and
cash received from Abbott.

In June 1993, NaPro entered into an initial 20 year exclusive agreement with
IVAX to develop and market paclitaxel in the United States, Europe, and other
parts of the world (the "IVAX Agreement"). NaPro and IVAX terminated the IVAX
Agreement on March 20, 1998. Under terms of the termination agreement, IVAX
received a royalty-free, limited, non-exclusive license to one of NaPro's
patents (the "Patent") in the United States, Europe and certain other world
markets. As consideration for this licence, NaPro received $4.1 million,
1,126,398 shares of NaPro common stock held by IVAX were returned to NaPro, and
an additional $2 million was placed in escrow to be released in installments
corresponding to delivery of NaPro's paclitaxel to IVAX. As a result of
deliveries of NaPro's paclitaxel to IVAX, $700,000 of this escrow amount had
been released to NaPro through December 31, 1998, and $1 million of the
remaining $1.3 million had been released as of August 27, 1999. In addition,
during 1998 IVAX made the following payments to NaPro: $3.8 million upon
issuance of the Patent in the United States, and $2.6 million upon issuance of
the Patent in the European Union.

In the normal course of its business, NaPro investigates, evaluates, and
discusses strategic relationship, joint venture, acquisition, and other business
combination opportunities. These opportunities could include, in the future,
strategic relationships to develop new classes of compounds NaPro has been
investigating, such as a new class of mitotic spindle poisons, a new class of
protein synthesis inhibitors, and a natural product that inhibits an enzyme
critical for the reproduction of cancer cells. Developing these opportunities or
others could require the expenditure of funds to secure licenses and for other
purposes. The amount and timing of future expenditures will depend upon numerous
factors, including the establishment of additional strategic relationships, the
progress of NaPro's research and development programs, the magnitude and scope
of these activities, the cost of preparing, filing, prosecuting, maintaining and
enforcing patent claims and other intellectual property rights, competing
technological and marketing developments, changes in or terminations of existing
strategic relationships and the cost of manufacturing scale-up. In the event of
any such relationships or transactions, NaPro may consider using available cash,
issuing equity securities or increasing its indebtedness.

Working Capital and Cash Flow. Cash and cash equivalents decreased $900,000 to
$7.2 million for the year ended December 31, 1998 from $8.1 million at December
31, 1997. Net cash provided by 1998 operations of $2.1 million was offset by
investing activity of $1.6 million and by financing activity of $1.4 million.

Inventory remained at $4.3 million at December 31, 1998 from December 31, 1997.
The amount of work-in-progress inventory and finished goods inventory is
dependent on a number of factors, including the shipping requirements of NaPro's
strategic partners and NaPro's production planning for meeting those needs.
Inventory balances may vary significantly during product development and launch
periods.

Capital Expenditures. NaPro expended $500,000 during 1998 for capital projects.
These expenditures primarily included plantation cost, work on manufacturing
facilities in Boulder, and improvements to NaPro's laboratories.

Since the FDA's determination that NaPro's paclitaxel could not be marketed in
the U.S. for Kaposi's Sarcoma during Bristol's period of exclusivity under the
Orphan Drug Act, NaPro has significantly reduced the scope of its operations and
has reduced or delayed capital expenditures. NaPro is seeking a new strategic
partner or partners to replace IVAX. The nature of NaPro's relationship with its
strategic partners may significantly change its planned capital expenditures.

The amount and timing of future capital expenditures will depend upon numerous
factors, including the establishment of additional strategic relationships, the
progress of NaPro's research and development programs, the magnitude and scope
of these activities, the cost of preparing, filing, prosecuting, maintaining and
enforcing patent claims and other intellectual property rights, competing
technological and marketing developments, changes in or terminations of existing
strategic relationships and the cost of manufacturing scaleup. NaPro may seek
additional long-term financing to fund capital expenditures should such
financing become available on terms acceptable to NaPro.

Net Operating Loss Carryforwards. As of December 31, 1998, NaPro had net
operating loss carryforwards for income tax purposes of approximately $34
million to offset future taxable income. Under Section 382 of the Internal
Revenue Code of 1986, as amended, the utilization of net operating loss
carryforwards is limited after an ownership change, as defined in such Section
382, to an annual amount equal to the value of the loss corporation's
outstanding stock immediately before the date of the ownership change multiplied
by the federal long-term tax-exempt rate in effect during the month the
ownership change occurred. Such an ownership change occurred in September 1993.
As a result, NaPro will be subject to an annual limitation on the use of its net
operating losses incurred prior to that date. This limitation only affects net
operating losses incurred up to the ownership change and does not reduce the
total amount of net operating loss which may be taken, but rather limits the
amount which may be used during a particular year. Therefore, in the event NaPro
achieves profitability, such limitation would have the effect of increasing
NaPro's tax liability and reducing the net income and available cash resources
of NaPro if the taxable income during a year exceeded the allowable loss carried
forward to that year.

Year 2000 Issue. Until recently many computer programs used only the last two
digits to refer to a year. Such programs do not properly recognize a year that
begins with "20" instead of the familiar "19". If not corrected, many computer
applications could fail or create erroneous results.
This matter is commonly referred to as the Year 2000 issue or Y2K.

Two years ago NaPro implemented an assessment of its systems and other assets
which could be subject to Y2K. NaPro has completed the assessment of its primary
systems and has brought all of the systems into Y2K compliance.

NaPro is assessing its secondary systems and other assets, including
microprocessor-controlled equipment, and expects to complete that assessment no
later than October 1999. The potential for significant interruption from
secondary systems exists, although NaPro believes that the likelihood of
interruption caused by Y2K failures in secondary systems is small.

In addition to its internal systems NaPro is evaluating potential impact on
NaPro of Y2K issues with its vendors and customers. NaPro cannot directly
control Y2K compliance by its vendors and customers. NaPro is communicating with
its key vendors and customers regarding this matter. NaPro knows of no vendor or
customer that has Y2K issues that have a potential of interrupting NaPro in a
manner that could significantly adversely affect NaPro's operations. However,
NaPro uses a number of vendors that NaPro believes to be the best or the only
qualified source of a particular good or service. Sales to NaPro's customers
potentially could be interrupted by customers' Y2K issues. Should a significant
customer incur Y2K problems with its testing, release or other systems, NaPro's
sales could be materially affected. NaPro will continue to monitor the level of
Y2K compliance with respect to its key vendors and customers and will further
develop contingency plans to cover the failure of a key vendor, including
identification and qualification of alternative suppliers. Management believes
that exposure to vendor or customer Y2K issues creates no material risk to
NaPro. However, no assurance can be given with certainty that Y2K issues with
vendors or customers will not significantly affect NaPro.

NaPro's Y2K effort has caused no significant deferral of other information
technology projects.

NaPro's Y2K contingency plan includes completion of the evaluation and
remediation process discussed above, including communication with its key
vendors and customers regarding potential for Y2K issues; identification of the
best alternative vendor for sensitive goods and services; coordination and
planning with such alternative vendors.

Management believes that Y2K issues related to both internal and external
systems will have no material effect on NaPro's business, results of operations
or financial condition, and that NaPro's Y2K risk is not material. However, no
such assurance can be given with certainty. The cost of addressing Y2K has not
been material; management believes that the cost of completing Y2K compliance
will not be material.

Special Note Regarding Forward-looking Statements

Certain statements in this Report constitute "forward-looking statements" within
the meaning of the federal securities laws, including the Private Securities
Reform Act of 1995. In addition, NaPro or persons acting on its behalf sometimes
make forward-looking statements in other written and oral communications.
Forward-looking statements can be identified by the use of words such as
"believes", "intends", "may", "should", "anticipates, "expected" or comparable
terminology or by discussions of strategies or trends. Such forward-looking
statements may also include, among other things: statements concerning NaPro's
plans, objectives and future economic prospects, such as matters relative to
seeking and obtaining additional strategic partners; the availability of patent
and other protection for its intellectual property; the completion of clinical
trials and regulatory filings; the prospects for and timing of regulatory
approvals; the need for and availability of additional capital; the amount and
timing of capital expenditures; the timing of product introductions and revenue;
the availability of raw materials; prospects for future operations; and other
statements of expectations, beliefs, future plans and


                                                        11

<PAGE>



strategies, anticipated events or trends and similar expressions concerning
matters that are not historical facts.

Such forward-looking statements involve known and unknown risks, uncertainties
and other factors which may cause the actual results, performance or
achievements of NaPro, or industry results, to be materially different from any
future results, performance or achievements expressed or implied by such
forward-looking statements. Such factors include, among other things, adverse
economic and general business conditions; competition from Bristol and other
existing and new producers of paclitaxel and other drugs; technological advances
in cancer treatment and drug development; the ability to obtain rights to
technology; the ability to obtain and enforce patents; the ability to obtain raw
materials and commercialize manufacturing processes; the effectiveness of NaPro
paclitaxel and other pharmaceuticals developed by NaPro in treating disease; the
results of clinical studies; the results of research and development activities;
the business abilities and judgment of NaPro's management and other personnel;
the availability of qualified personnel generally; changes in and compliance
with governmental regulations; the effect of capital market conditions and other
factors on capital availability for NaPro and other biopharmaceutical companies;
the ability of Abbott and Faulding to perform their obligations under their
existing agreements with NaPro; the effect on NaPro's revenue, cash flow and
earnings from foreign exchange rate fluctuations; the ability of NaPro to
establish relationships with capable strategic partners to develop and market
NaPro paclitaxel in the territories not covered by the Abbott and Faulding
agreements; any Y2K issues of NaPro, its customers or vendors; and other factors
described or referenced in this Report.

Quantitative and Qualitative Disclosures about Market Risk

Following the final delivery of product to IVAX in August 1999 under the
Termination Agreement, sales of NaPro paclitaxel to Faulding will constitute
substantially all of NaPro's revenue until NaPro begins making sales to Abbott
under the Abbott Agreement. Faulding purchases NaPro paclitaxel at a price which
varies in proportion to the price at which Faulding sells the product.
Faulding's sales are made in the currencies of each of the countries in which it
sells NaPro paclitaxel. As a result, NaPro's revenue from sales is affected by
fluctuations in the value of these various foreign currencies relative to the
U.S. dollar. Faulding's largest single market is Australia, accounting for
approximately 39% of Faulding's commercial sales during the year ended March
1999. If changes in foreign currency markets cause a decrease in the price per
gram NaPro receives from Faulding, there could be a material adverse effect on
NaPro's earnings and cash flow. For example, during the year ended March 1999,
NaPro's revenue attributable to sales of NaPro paclitaxel to be resold
commercially by Faulding totaled $2.2 million. Had there been negative pressure
on the relevant exchange rates such that the price had been reduced by 20%,
NaPro's revenue for the year ended March 1999 would have been reduced by
approximately $400,000 and NaPro would have experienced materially reduced cash
flow. While sales to Faulding will continue to have a significant impact on
NaPro's revenue in the near term, NaPro's future revenue and success will be
dependent upon obtaining regulatory approvals and on Abbott's success in
marketing NaPro paclitaxel, of which there can be no assurance.

NaPro's fixed rate indebtedness was represented by its senior convertible debt.
All of the debt had either been converted, repurchased or redeemed by July 26,
1999. On July 26, 1999, NaPro borrowed $2 million from Abbott under a credit
facility under which, subject to certain conditions, it may borrow up to $20
million. As this loan bears interest at a fixed rate of 6.5%, NaPro's
indebtedness under this loan will not be sensitive to market rate fluctuations.
NaPro currently does not use derivative financial instruments to manage its
interest rate risk and has no cash flow exposure due to general interest rate
changes for its fixed interest rate debt.

Certain statements set forth in this discussion constitute "forward-looking
statements" within the meaning of the Reform Act. See "Special Note Regarding
Forward-looking Statements".

promptly such license(s) to such Third Party Technology at Abbott's sole cost
and expense (including, but not limited to, any up-front license fees,
milestones and any royalties).
                  2.3.3 Other than Related to NaPro or Abbott Formulated
Product. In the event that a license to any Third Party Technology is required
in order to manufacture, use (including, but not limited to in connection with
the Development Program), market or sell any Finished Product other than the
NaPro Formulated Product or the Abbott Formulated Product, (in each such case,
without infringement of such Third Party Technology) then the Parties jointly
through the Development Committee shall determine the strategy to pursue and
obtain such license in the Territory. Neither Party shall commit to license such
Third Party Technology without the prior written agreement of the other Party.
Unless otherwise agreed to by the Parties in writing, Abbott and NaPro shall
each share equally in, and each shall be responsible for, fifty percent (50%) of
the total cost and expense to secure and maintain such license(s) including, but
not limited to, any up front license fees, milestones and royalties.

                           3.1.8.2  in the event that Abbott directs (such

Program.  Any disagreement or dispute regarding the milestone payment pursuant
to Section 3.1.2 shall be resolved pursuant to the provisions set forth in
Section 6.4.
         3.2 Single Payment Obligation. Each milestone payment set forth in
Section 3.1 shall not be made more than once with respect to the Finished
Product(s), regardless of the formulation(s) developed (e.g., the NaPro
Formulated Product, Abbott Formulated Product or NaPro Oral Formulated Product)
the number of Applications for Regulatory Approval in the Territory, clinical
trials or Regulatory Approvals that may be undertaken or granted with respect to
the Finished Product(s), including, without limitation, such activities with
multiple product forms or formulations of any Finished Product(s), combinations
with different and/or additional active or inactive ingredients, additional
indications, different delivery modalities and/or various dosage strengths. For
the avoidance of doubt, in the event that the Abbott Formulated Product or NaPro
Oral Formulated Product is pursued either in lieu of or in addition to the NaPro
Formulated Product, any milestone set forth in Section 3.1 shall be paid only
once during the Term and shall not be paid again.
         3.3 Other Funding. Abbott has also agreed to provide funding for
NaPro's general working capital and operational needs under: (a) the Loan
Agreement pursuant to which Abbott shall lend NaPro up to Twenty Million Dollars

therein; and (b) the Stock Purchase Agreement pursuant to which Abbott shall
purchase up to two million (2,000,000) shares of Common Stock of NaPro as
provided in and pursuant to the terms of the Stock Purchase Agreement.
         3.4 Use of Certain Milestone Payments. NaPro and Abbott agree that the
funds from milestone payments set forth in both Sections 3.1.1 and 3.1.2 shall
be used solely for purposes of the Development Program.

                      ADDITIONAL FINISHED PRODUCT PAYMENTS
         4.1 Additional Consideration. In further consideration of the supply of
Bulk Drug to Abbott hereunder, Abbott shall pay to NaPro additional
consideration equal to a portion of Abbott=s Net Sales in every Sales Year
during the Term as follows:
                  4.1.1 [THIS PORTION HAS BEEN REDACTED.] of Net Sales of all
Finished Product other than Abbott Formulated Product in an amount up to but not
including [THIS PORTION HAS BEEN REDACTED.] in a single Sales Year;
                  4.1.2 [THIS PORTION HAS BEEN REDACTED.] of Net Sales of all
Finished Product other than Abbott Formulated Product in an amount from [THIS
PORTION HAS BEEN REDACTED.] in a single Sales Year; and
                  4.1.3 [THIS PORTION HAS BEEN REDACTED.] of Net Sales of all
Finished Product other than Abbott Formulated Product in an amount of [THIS
PORTION HAS BEEN REDACTED.]
                   LESS (in all cases set forth in Section 4.1) the cost of Bulk
Drug for Commercial Use paid by Abbott pursuant to Section 8.2, 8.3 or Section
8.7 (the difference being the "Additional Consideration"). For clarification
purposes in calculating, the cost of Bulk Drug shall be subtracted after the
Applicable Percentage is applied to Net Sales.
Notwithstanding the foregoing, in the event there is a Competitive Paclitaxel
Product being marketed and/or sold in any country in the Territory, with respect
to that country in which the Competitive Paclitaxel Product is being marketed
and/or sold, each of the percentage amounts specified in Sections 4.1.1 through
4.1.3, inclusive ("Applicable Percentages") shall be reduced as set forth in
Section 4.3. In the event that the calculation of a stated percentage of Net
Sales less the cost of Bulk Drug results in a negative number, such that no
Additional Consideration would be due by Abbott to NaPro, the negative number
shall be carried forward to the next (one or more) Sales Years as a credit
against the next payments

has been fully applied or until there are no more Net Sales pursuant to this
Agreement.
         4.2 Abbott Formulated Product in Lieu of or in Addition to NaPro
Formulated Product. Notwithstanding the provisions in Section 4.1, in the event
that the Abbott Formulated Product is marketed and sold in lieu of or in
addition to the NaPro Formulated Product, Abbott shall pay to NaPro Additional
Consideration equal to a portion of Abbott's Net Sales in every Sales Year
during the Term as follows:
                  4.2.1 [THIS PORTION HAS BEEN REDACTED.] of Net Sales of Abbott
Formulated Product in an amount up to but not including [THIS PORTION HAS BEEN
REDACTED.] in a single Sales Year;
                  4.2.2 [THIS PORTION HAS BEEN REDACTED.] of Net Sales of Abbott
Formulated Product in an amount from [THIS PORTION HAS BEEN REDACTED.] in a
single Sales Year;
                  4.2.3 [THIS PORTION HAS BEEN REDACTED.] of Net Sales of Abbott
Formulated Product in an amount of [THIS PORTION HAS BEEN REDACTED.] or more in
a single Sales Year;
                   LESS (in all cases set forth in Section 4.2) the cost of Bulk
Drug for Commercial Use paid by Abbott pursuant to Section 8.2 or Section 8.7
(the difference being the "Additional Consideration"). For clarification
purposes in calculating, the cost of Bulk Drug shall be subtracted after the
Applicable Percentage is applied to Net Sales.

Notwithstanding the foregoing, in the event there is a Competitive Paclitaxel
Product being marketed and/or sold in any country in the Territory, with respect
to the country in which the Competitive Paclitaxel Product is being marketed
and/or sold, each of the percentage amounts specified in Sections 4.2.1 through
4.2.3, inclusive ("Applicable Percentages") shall be reduced as set forth in
Section 4.3. In the event that the calculation of a stated percentage of Net
Sales less the cost of Bulk Drug results in a negative number, such that no

Additional Consideration would be due by Abbott to NaPro, the negative number
shall be carried forward to the next (one or more) Sales Years as a credit
against the next payments of Additional Consideration otherwise owed by Abbott
to NaPro until such credit has been fully applied or until there are no Net
Sales pursuant to this Agreement.
         4.3 Reduction in Applicable Percentages Due to Competitive Paclitaxel
Product. Notwithstanding Section 4.1 and Section 4.2, with respect to the sale
of a particular Finished Product in any country in the Territory in which a
Competitive Paclitaxel Product (of same or similar formulation or mode of
delivery) is also marketed and/or sold:
                  4.3.1 If the Average Selling Price or Finished Product Sales
Volume has been reduced by as much as [THIS PORTION HAS BEEN REDACTED.] lower
than it was for the Base Period but less than [THIS PORTION HAS BEEN REDACTED.]
lower than it was for the Base Period, then the Applicable Percentages shall be
as follows:
                           4.3.1.1 in the case of Section 4.1.1, [THIS PORTION
HAS BEEN REDACTED.]
                           4.3.1.2 in the case of Section 4.1.2, [THIS PORTION

Base Period then Abbott and NaPro shall meet to renegotiate and revise in good
faith the rate applied to Net Sales to be used in the calculation of Additional
Consideration and the Applicable Percentages to share available profit on a
basis equivalent to that set forth in Sections 4.1 through 4.3 and profit
distribution as originally contemplated by the Parties in this Article 4.
         In any Sales Year following the reduction of the Applicable Percentages
required by the foregoing clauses 4.3.1 and 4.3.2, and regardless of whether a
Competitive Paclitaxel Product is being sold in such following Sales Year, when
and if the Average Selling Price is less than [THIS PORTION HAS BEEN REDACTED.]
lower than it was for the Base Period with respect to which the Applicable
Percentage was reduced for not less than two (2) Consecutive Calendar Quarters,
then the Applicable Percentage shall be restored to the amounts specified in
Sections 4.1.1 through 4.1.3 and/or 4.2.1 through 4.2.3, as applicable. Any
increases and decreases in the Applicable Percentages required by this Section
4.3 shall take effect thirty (30) days after the Average Selling Price has
either increased or decreased and the Applicable Percentage adjusted
accordingly.
         4.4 Adjustments to Additional Consideration. In addition to adjustments
due to a Competitive Paclitaxel Product, as set forth in Section 4.1 through
4.3, the amount of Additional Consideration payable with respect to each
Calendar Quarter as determined by Sections 4.1 through 4.3 shall be further
decreased (but not to less than zero) by any excess cost to manufacture Bulk
Drug by Abbott's Stand-by Manufacturing Source as set forth in Section 8.7.2.
Such reduction for excess cost to manufacture Bulk Drug shall be applied after
the reduction for the cost of Bulk Drug specified in Section 4.1 or 4.2.
         4.5 Increase or Decrease in Additional Consideration for Additional
Licenses. In the event that a license to any Third Party Technology is required
as set forth in Section 2.3.1, 2.3.2 or 2.3.3 there shall be no change in
Additional Consideration.
         4.6      Net Sales Reports and Payments.  Commencing with the first
Calendar Quarter in which Abbott makes the First Commercial Sale in the
Territory, Abbott shall

provide NaPro with a written report of Net Sales on a country-by-country basis:
(a) within forty-five (45) days after the last day of March, June, September and
December and the related computation of Additional Consideration accruing on Net
Sales in the United States during the three (3) preceding calendar months; and
(b) within seventy-five (75) days after the last day of February, May, August
and November and the related computation of Additional Consideration accruing on
Net Sales in the Territory in countries other than the United States during the
three (3) preceding calendar months. Concurrently with the submission of each
such written report, Abbott shall pay or cause to be paid to NaPro the total
amount shown to be due thereon. The periods set forth in (b) above shall be
modified to accommodate sales reporting practices of Abbott's International
Division.
         4.7 Currency. Abbott shall make all payments to NaPro pursuant to this
Agreement in Dollars. Additional Consideration shall be first determined by
Abbott in the currency of the country where the Net Sales were made and then
converted by Abbott directly to its equivalent in Dollars. The rates of exchange
for converting the currencies involved to Dollars as quoted by The Wall Street
Journal, Midwest Edition, as Foreign Exchange Rates based on the average of the
market rate at the last Business Day of the prior Calendar Quarter and the last
Business Day of the current Calendar Quarter in which the Additional
Consideration was earned shall be used by Abbott to determine such conversion
rates.
         4.8 Sales Between Abbott and Affiliates. No Additional Consideration
shall be payable to NaPro on sales between Abbott and its Affiliates or on sales
between Abbott or its Affiliates and distributors.
         4.9 Loan Agreement Offset. In the event of an Event of Default (as
defined in the Loan Agreement) by NaPro (that is not subject to a bone fide
dispute by NaPro as permitted pursuant to the Loan Agreement) on any payments
due to Abbott pursuant to the terms of the Loan Agreement by a period of time in
excess of thirty (30) days, in addition to any and all rights Abbott may have
under the Loan Agreement Abbott may, at Abbott's

option, offset any payment due NaPro for milestone or Additional Consideration
against payments due by NaPro to Abbott pursuant to the Loan Agreement
(including principal, interest and any applicable penalties). Any withholding or
offset of payments for milestones or Additional Consideration by Abbott pursuant
to this Section 4.9 shall not constitute a breach, Material Breach or any other
default by Abbott under this Agreement or waiver of NaPro's obligations under
the Stock Purchase Agreement or the Loan Agreement.

                    PAYMENT, RECORD KEEPING AND AUDIT RIGHTS
         5.1 Method of Payment. All payments by either Party to the other Party
under this Agreement (including, but not limited to, Abbott's milestone payments
under Article 3, research and development payments under Article 6, and
Additional Consideration payments under Article 4) shall (except as expressly
permitted by this Agreement) be made without deduction of any withholdings for
any purposes other than taxes, if applicable, to the extent required by law. In
the event of any tax withholding or other withholding permitted pursuant to this
Agreement, the paying Party shall provide the receiving Party with the best
available evidence of the taxes or other amount withheld as well as any relevant
certificates, documents or other evidence required for national, state or local
tax credit and reporting purposes. Abbott may offset payments for milestones or
Additional Consideration owing to NaPro against any amounts owed by NaPro to
Abbott which are past due except for those amounts disputed in good faith by
NaPro. Payments hereunder shall not be creditable against any other amounts
payable by the other Party under this Agreement, except as otherwise expressly
stated in this Agreement. Payments shall be made by either wire transfer or
electronic funds transfer to an account designated by the receiving Party in
advance and in writing.
         5.2      Record Keeping and Audit Rights.  Each Party shall keep or
cause to be kept accurate records relating to Net Sales, Additional

either Party to the other Party in sufficient detail to enable the amounts
payable hereunder to be determined.
                  5.2.1 Audit of Net Sales. For the purposes of verifying Net
Sales and other payments due to NaPro under this Agreement, Abbott shall on an
annual basis prior to May 31 of each Sales Year provide its report of payments
of Additional Consideration due by Abbott to NaPro to the auditors for NaPro
including a report on sales of Finished Product by Finished Product in each of
the countries within the Territory as well as information on all applicable
selling prices in each of the countries within the Territory, and other records
pertinent to the loss, corruption, contamination, or destruction of Finished
Product. NaPro, at its expense (except as provided below), shall have the right
to hire an independent accountant, upon reasonable notice and during normal
business hours but not more than once per Sales Year, to review Abbott's books
and records relating to Net Sales or other payments of Additional Consideration
or milestones made pursuant to this Agreement. If there is an underpayment
disclosed during such audit, Abbott shall promptly pay NaPro the amount of such
underpayment. If there is an overpayment disclosed during such audit, NaPro

Abbott. Abbott shall use its reasonable commercial efforts to obtain approval
from the FDA or other regulatory authorities (in countries within the Territory
outside the United States) for NaPro's name to appear on the package insert as
the manufacturer of the Bulk Drug. In the event that the FDA or other regulatory
authority does not grant approval for the identification of NaPro as the
manufacturer of the Bulk Drug on the Finished Product package insert, Abbott
shall have no obligation to identify NaPro as the manufacturer of the Bulk Drug
or pursue the matter further. In the event that the FDA or other regulatory
authority approves the identification of NaPro as the manufacturer of Bulk Drug,
NaPro shall grant to Abbott the royalty-free right to use and print NaPro's name
and if desired by Abbott, corporate logo and trademark on the package insert. In
the event that Abbott has need to purchase Bulk Drug from a Stand-By
Manufacturing Source, and Abbott is required to change the package insert or
such other packaging which identifies NaPro as the Bulk Drug manufacturer, NaPro
shall pay all costs incurred by Abbott to change the package insert for Finished
Product containing Bulk Drug manufactured by the Stand-By Manufacturing Source.

agreement) a development plan and substantive data, including proof of principle
(which may or may not include human data), for that NaPro Pro-Drug in order to
allow Abbott to adequately evaluate the opportunity to collaborate with NaPro on
the NaPro Pro-Drug and include the NaPro Pro-Drug in the Development Program.
NaPro shall allow Abbott not less than ninety (90) Business Days to evaluate the
opportunity. During such ninety (90) day period, NaPro shall not discuss the
NaPro Pro-Drug opportunity with any Third Party. If Abbott is interested in
working with NaPro on the NaPro Pro-Drug and including the NaPro Pro-Drug in the
Development Program, Abbott shall so notify NaPro in a writing executed by the
President of Abbott's Hospital Products Division and the NaPro Pro-Drug shall be
included within Development Program and the definition of "Finished Product"
under this Agreement shall include any Pro-Drug, whether developed by Abbott or
NaPro. Abbott shall not be obligated to pay any milestone payments (except
payments that would be due under Sections 3.1.2 through 3.1.8 which have not

with the NaPro Pro-Drug, other than through sharing expenses for the research
and development in connection with the development and Regulatory Approval of
the NaPro Pro-Drug as a Finished Product as contemplated by Section 6.2. In the
event that Abbott does not elect to include NaPro Pro-Drug in the Development
Program and within the definition of "Finished Product", NaPro may develop the
NaPro Pro-Drug on its own and Abbott shall not have rights to that certain NaPro
Pro- Drug Product in the Territory.

excess cost for the Bulk Drug from the Stand-By Manufacturing Source shall be
credited against the Additional Consideration; or

                            8.7.2.2 if Abbott used a Stand-By Manufacturing
Source because NaPro was not able to supply Abbott's requirements of Bulk Drug
and such requirements did not exceed [THIS PORTION HAS BEEN REDACTED.] of Bulk
Drug Forecast, such excess cost, for amounts not to exceed [THIS PORTION HAS
BEEN REDACTED.] of the Bulk Drug Forecast, for the Bulk Drug from the Stand-By
Manufacturing Source shall be credited against Additional Consideration;

                            8.7.2.3 if Abbott used a Stand-By Manufacturing
Source because NaPro was not able to supply Abbott's requirements of Bulk Drug
and such requirements exceeded [THIS PORTION HAS BEEN REDACTED.] of Bulk Drug
Forecast, such excess cost for the Bulk Drug from the Stand-By Manufacturing
Source shall be at Abbott's expense and shall not be credited against Additional
Consideration; or

                            8.7.2.4 if Abbott used a Stand-By Manufacturing
Source because NaPro was unable to supply to Abbott Bulk Drug which in the
manufacture or sale thereof did not infringe any Third Party Technology, such
excess cost for Bulk Drug from the Stand-By Manufacturing Source shall be
credited against the Additional Consideration.

                  8.7.3 Transition of Manufacturing Back to NaPro. Abbott may
purchase Bulk Drug from the Stand-By Manufacturing Source until such time as
NaPro demonstrates to Abbott's reasonable satisfaction that it is able to

back to NaPro. Subject to Abbott's commitments to the Stand-By Manufacturing
Source, Abbott shall transition its supply of Bulk Drug back to NaPro, as soon
as practicable, taking into consideration Abbott's contractual arrangements with
the Stand-By Manufacturing Source, but in any event not later than [THIS PORTION
HAS BEEN REDACTED.] after NaPro has made the demonstration to Abbott set forth
in this Section 8.7.3.
                  8.7.4 Continued Supply Obligations. Notwithstanding Abbott's
identification, qualification, and/or use of a Stand-by Manufacturing Source,
NaPro shall not be relieved of its supply obligations under Article 8 and Abbott
shall not be relieved of its obligation to pay NaPro the Additional
Consideration (subject to the crediting of Bulk Drug costs against Additional
Consideration as permitted by this Section 8.7 and Section 4). In the event that
Abbott utilizes a Stand-By Manufacturing Source due to a NaPro supply constraint
(as opposed to NaPro's failure to provide Bulk Drug that meets the Bulk Drug
Specifications, or a complete inability of NaPro to supply), then Abbott shall
purchase from NaPro, pursuant to the terms of this Agreement, Bulk Drug which

                   8.8.3 NaPro Supply Constraints. In the event that NaPro
believes that it may be unable to supply all of Abbott's requirements for Bulk
Drug, then NaPro shall promptly provide Abbott with notice and NaPro and Abbott
shall promptly meet to discuss Abbott's Bulk Drug requirements and NaPro's
supply capabilities, including the possibility

of utilizing a Stand-By Manufacturing Source. At such meeting, NaPro shall
provide to Abbott NaPro's good faith estimate of the amount of Bulk Drug which
NaPro is capable of supplying for the then current Bulk Drug Forecast period.
                  8.8.4 Orders. From time to time during the Term, Abbott shall
submit to NaPro purchase orders for quantities of Bulk Drug for research and
development and for Commercial Use and, subject to limitations set forth in
Section 8.8.1, NaPro shall fill all purchase orders for Bulk Drug received from
Abbott and Abbott shall accept delivery of such ordered quantities of Bulk Drug.
Orders shall be entered on Abbott purchase orders. Issued purchase orders shall
include the quantity of Bulk Drug ordered and the date on which the Bulk Drug
shall be delivered to Abbott. All terms and conditions of the Abbott purchase
order shall apply, except that if the terms and conditions of the purchase order
are in conflict with this Agreement, then this Agreement shall control unless
otherwise agreed by the Parties in writing.
                  8.8.5    Required Inventory. [THIS PORTION HAS BEEN REDACTED.]

         8.9 Supply Allocation. If NaPro is unable, for any reason beyond its
reasonable control (including but not limited to a force majeure event as
described in Section 18.1 or an unanticipated increase in demand) to supply Bulk
Drug to Abbott under this Agreement and to Third Parties under then existing
contractual obligations outside the Territory, then NaPro shall establish an
allocation procedure with respect to the total available supply of Bulk Drug
which will provide the following allocation to Abbott:
                  8.9.1 First, an amount of Bulk Drug sufficient to satisfy any
warranty obligation to replace any nonconforming Bulk Drug due to Abbott at the
time of such allocation; provided, however, that if the total available supply
is insufficient to satisfy such obligation to Abbott plus all of NaPro's similar
warranty obligations to other purchasers or users, then this allocation shall be
made pro rata among all purchasers or users including Abbott (the pro rata share
of each purchaser or user to be determined by multiplying the total

available supply of Bulk Drug by a fraction, the numerator of which shall be the
amount of Bulk Drug required to satisfy the warranty obligation to such
purchaser or user and the denominator of which shall be the amount of Bulk Drug
required to satisfy the warranty obligation to all purchasers or users,
including Abbott); and
                  8.9.2 Next, a fraction of the remaining supply (if any) of
Bulk Drug, as applicable, the numerator of which fraction shall be the
quantities of Bulk Drug which Abbott has forecasted pursuant to the Bulk Drug
Forecast for the next four (4) Calendar Quarters, and the denominator of which
shall be the quantities of Bulk Drug which is forecasted by all purchasers or
users (including Abbott) during such four (4) Calendar Quarters, as determined
by such parties' latest firm orders and forecasts submitted to NaPro for such
Calendar Quarters.
                  8.9.3 The Parties shall use commercially reasonable efforts to
avoid any circumstances which would require allocation under this Section 8.9
and to eliminate such circumstances as soon as reasonably possible if they
arise.
                  8.9.4 Notwithstanding the provisions of this Section 8.9,
Abbott shall be NaPro's preferred customer for Commercial Use along with F. H.
Faulding. In the event of shortage of Bulk Drug for any reason, Abbott and F.H.
Faulding shall receive priority and preference for supply of Bulk Drug over any
purchaser not under written contract to purchase Bulk Drug from NaPro as of the
Effective Date. Notwithstanding the foregoing, the supply of Bulk Drug for
development purposes in the Development Program shall have priority and
preference over any other proposed disposition of Bulk Drug by NaPro.

                FINISHED PRODUCT MANUFACTURE, MARKETING AND SALE
         9.1 Abbott Manufacture and Labeling of Finished Product. Abbott shall
manufacture or have manufactured the Finished Product in accordance with the
Finished Product Specifications and applicable GMP for the Finished Product.
Abbott shall package

and label the Finished Product in a form and manner suitable for commercial sale
in the Territory. Abbott shall be responsible for all labeling, inserts,
promotional materials and any other materials which accompany, are distributed,
used or referred to in any way by Abbott or any Party or Third Party as provided
for in this Agreement in connection with the Commercial Use of the Finished
Product.
         9.2 Marketing Committee. The Marketing Committee shall provide
recommendations to Abbott on marketing strategies, marketing/promotional
programs and publications, technical marketing, and other marketing activities
which Abbott may consider or use in marketing, selling and distributing the
Finished Product. Abbott shall determine and establish all marketing,
promotional and sales strategies and determine the marketing, promotional and
sales activities which are likely to optimize Finished Product sales. Abbott
shall discuss the strategies and activities with the Marketing Committee. During
the twelve (12) month period preceding the anticipated date of First Commercial
Sale, the Marketing Committee shall meet once per calendar quarter. Following
the date of First Commercial Sale, the Marketing Committee shall meet once per
year.
         9.3 Abbott Marketing and Sales Efforts. Abbott and Abbott's Affiliates
shall use commercially reasonable efforts to market, sell and distribute the
Finished Product in the Territory. Abbott shall commence marketing and selling
the Finished Product within a reasonable time following the Approval Date.
Notwithstanding the foregoing, failure on the part of NaPro to supply quantities
of Bulk Drug ordered by Abbott which conforms with the Bulk Drug Specifications
in a timely manner pursuant to the orders for Bulk Drug shall not constitute a
failure on the part of Abbott to use commercially reasonable efforts as required
pursuant to this Section 9.3. Abbott and is Affiliates and distributors shall be
solely responsible for establishing price and other financial terms for the sale
of Finished Products to End-User Customers. Notwithstanding the foregoing, for
countries or areas in the Territory outside the United States, in the event that
Abbott, in its sole discretion, determines that the Finished Product either
lacks commercial viability, or its commercial

opportunity is compromised due to the existence of one or more Competitive
Paclitaxel Products, or if it is determined by Abbott not to take steps toward
filing and decides not to file, Abbott shall not be obligated to launch, market
or sell Finished Product in such countries or areas in the Territory outside the
United States. In the event that Abbott does not diligently pursue Regulatory
Approval or launch, market and sell the Finished Product in any such country or
area outside the United States [THIS PORTION HAS BEEN REDACTED.] Abbott shall
offer the opportunity for such country or area to NaPro for rights to
manufacture, market and supply the Finished Product. Notwithstanding the
foregoing, in the event that any legal, regulatory or other event including, but
not limited to an injunction, were to prevent the Regulatory Approval, launch,
marketing or sale of the Finished Product, [THIS PORTION HAS BEEN REDACTED.]
shall be extended for an equivalent period of time as such legal, regulatory or
other event delayed the Regulatory Approval, launch, marketing or sale of the
Finished Product. Notwithstanding the foregoing, if Abbott has offered the
opportunity to NaPro, Abbott shall not have breached the terms of this Article 9
or any other terms of this Agreement, whether or not NaPro launches, markets or
sells the Finished Product in such country or area within the Territory. NaPro's
acceptance of such offer shall be deemed a termination of this Agreement as to
the country or area in question, and the definition of the term "Territory"
shall be deemed thereby to have been amended to exclude that country or area.
NaPro's rights to develop products containing Paclitaxel for manufacture, use
and sale in that country or area shall include the right to use and reference
Paclitaxel Data in the Field only in that country or area without any of the
limitations imposed by Article 11 of this Agreement. Subject to Section 9.7,
Abbott shall have no obligation to manufacture Finished Product for such country
or area.
         9.4 NaPro Assistance with Technical Marketing. Abbott shall establish
the strategy for technical marketing of the Finished Product. NaPro may assist
Abbott with technical marketing of the Finished Product at NaPro's cost and
expense beginning not

earlier than the number of months determined by the Marketing Committee
following the First Commercial Sale of the Finished Product in the United
States. Such technical marketing performed by NaPro may include participation
(in conjunction with an Abbott representative) in symposia, conventions, and
trade shows, in the oncology market. Representatives of NaPro involved in
technical marketing shall be appropriately trained as experts in the Field
(defined as medical or technical personnel with specific knowledge and training
in oncology practice). NaPro shall limit the number of NaPro representatives
involved in technical marketing activities to five (5) employees of NaPro, so as
to allow proper coordination with Abbott. If NaPro participates in the technical
marketing, NaPro and Abbott shall work together to coordinate the technical
marketing for the Finished Product so as to present a uniform marketing program
to End-User Customers. All materials and technical marketing programs must be
approved prior to use by the Marketing Committee.
         9.5 Co-Promotion of Finished Product. In the event that Abbott is in
Material Breach of Abbott's obligation under Section 9.3 and such Material
Breach has not been cured by Abbott within ninety (90) days following the
written decision of the neutral in an ADR proceeding brought under Exhibit G,
NaPro may, at its option, itself establish a sales force to co-promote the
Finished Product along with Abbott at NaPro's sole expense. Subject to NaPro's
assistance with technical marketing, Abbott shall remain responsible for all
Finished Product marketing and sales. Any co-promotion activities by NaPro must
be approved by Abbott and shall comply with: (a) the marketing strategies
employed by Abbott; and (b) applicable regulations of the FDA and or other
regulatory authorities. All publications or promotional materials used by NaPro
in its co-promotion activities must be approved by the Marketing Committee in
advance of any dissemination. The percentage of Net Sales on which Additional
Consideration pursuant to Sections 4.1 through 4.3 are made shall not be
adjusted in the event that NaPro co-promotes the Finished Product.

Furthermore, NaPro may challenge Abbott's failure to comply with the terms of
this Article 9 only one (1) time per Sales Year.
         9.6 Trademarks. In the event that Abbott desires to pursue trademark
protection for the Finished Product, Abbott shall, at its sole discretion,
select and protect such trademark. Any such trademark or trademark application
shall be owned exclusively by Abbott, and NaPro shall have no rights to such
trademark(s) during the Term or thereafter, except as provided in Sections
15.6.2 or 15.6.3 as otherwise expressly agreed to in writing by Abbott.
         9.7 Manufacturing of Other Formulated Products. From time to time
during the Term, NaPro may request Abbott to consider manufacturing formulated
products containing Paclitaxel for sale by NaPro or other persons outside the
Field or outside the Territory. Upon such request by NaPro, Abbott shall
negotiate in good faith with NaPro with respect to such request.

its own expense, take all reasonable steps to prosecute and maintain NaPro
Patent Rights in the Territory or in certain countries outside the Territory
pursuant to the last sentence of Section 2.1. NaPro shall: (a) provide Abbott
with copies of all documents related to prosecution of NaPro Patent Rights; and
(b) permit Abbott to communicate directly with the attorney responsible for
NaPro Patent Rights. Notwithstanding the foregoing, NaPro shall not be obligated
either: (a) to prosecute any NaPro Patent Rights outside of the Territory solely
to permit Abbott to manufacture Finished product outside of the Territory; or
(b) to consult with Abbott with respect to any NaPro Patent Rights outside of
the Territory.
                  10.1.2 Abbott shall, through counsel of its own choosing and

         10.2     Program Invention
                  10.2.1 Invention Disclosure. Program Inventions and Third
Party Technology (except inventions directed to the manufacture of Bulk Drug)
shall be promptly disclosed by the originating Party to the other Party.
                  10.2.2 Ownership. Ownership of all Program Inventions shall be
vested, respectively, in the Party that invents and jointly by the Parties if
jointly invented with the inventorship of all such Program Inventions determined
according to United States patent law. In the event the Parties cannot agree on
the determination of inventorship of a Program Invention, the Parties shall
jointly select and retain independent patent counsel to determine inventorship.
The determination shall be binding on both parties and each party shall pay one-
half of any costs associated with such determination.
                  10.2.3   Prosecution and Maintenance
                   (a) With respect to any Program Inventions owned solely by
one of the Parties, that Party shall be responsible for and control all
decisions and all costs and expenses related to whether and where to file for
patent protection, as well as for the preparation, filing (foreign and/or
domestic), prosecution, issuance and maintenance of patent applications and/or
patents resulting from such Program Inventions. The responsible Party for such
expenses shall inform the other Party at regular intervals, or on written
request, about the status of all patent applications or patents for which it is
responsible under this Section 10.2.3(a).
                   (b) With respect to any Joint Patent Rights and any
counterparts outside the Territory, the parties shall select independent patent
counsel, mutually acceptable to both Parties, for the preparation, filing

Rights. The parties shall mutually agree and instruct such patent counsel as to
the patent applications and/or patents covering such Joint Patent Rights. If the
Parties cannot agree, the issue shall be reviewed by the Development Committee
whose decision shall be final. Abbott shall be responsible for all costs and
expenses incurred under this Section 10.2.3(b) within the Territory. NaPro shall
be responsible for all costs and expenses incurred under this Section 10.2.3(b)
outside the Territory.
                  10.2.4 Trade Secrets. Should NaPro or Abbott elect not to
file, continue prosecution, or permit issuance of a patent application on a
Program Invention that is solely owned by either Party, the other Party shall
have no right to assume responsibility for an application for patent on such
invention.
                  10.2.5 Cooperation. Each Party shall cooperate with and make
available to the other Party or its authorized attorneys, agents,
representatives, employees or consultants all reasonable assistance necessary or
appropriate to enable the other Party to prepare, file, prosecute and maintain
patent applications and/or resulting patents claiming any Program Invention(s)
or Joint Program Invention(s). Each Party shall provide such cooperation as well
as sign or cause to have signed all documents relating to said patent
applications and/or patents at no charge to the other Party.
         10.3 No Other Technology Rights. Except as otherwise specifically
provided in this Agreement, under no circumstances shall a Party hereto or its
sublicensee(s), as a result of this Agreement, obtain any ownership interest or
other right in any pending patent application(s), license(s) or product(s),
including items owned, controlled or developed by, the other Party, or
transferred by the other Party to such Party at any time pursuant to this
Agreement. Each Party covenants that it shall not use or practice any of the
other Party's technology licensed under this Agreement for any purpose except as
expressly permitted in this Agreement.

         11.2 Abbott Right of First Refusal for Development Opportunities. From
time to time following the Effective Date, in the event that: (a) one or more of
the Unavailable Territories shall become available either because (i) the Other
Territory Rights of F.H. Faulding shall cease to be exclusive or (ii) any of the
negotiations referred to in Section 11.1.1(b) (with respect to the Third Party
with which NaPro is in negotiations with or has granted other Territory Rights
to as of the Effective Date) shall terminate within two (2) years following the
Effective Date without NaPro having entered into a license or similar
arrangement granting Other Territory Rights and/or Expanded Field Rights, or
once a license or similar arrangement is entered into covering Other Territory
Rights and/or Expanded Field Rights and such arrangement later ceases to be
exclusive; or (b) the Exclusive Option Period has ended and NaPro desires to
solicit or consider offers from any Third Party with respect to the Other
Territory Rights and/or Expanded Field Rights in any particular country; then
NaPro shall give Abbott written notice of its intent to undertake development,
marketing or sale of products containing Paclitaxel in the previously
Unavailable Territory or to grant Other Territory Rights and/or Expanded Field
Rights in any particular country (each a "Development Opportunity" and
collectively the "Development Opportunities").
         Upon the giving of such notice of a Development Opportunity: (x) NaPro
and Abbott shall have the rights and obligations specified in Section 11.3 if
the Development Opportunity would include the use of, or right of reference to,
Paclitaxel Data; and (y) NaPro and Abbott shall have the rights and obligations

a written notice pursuant to Section 11.2, Abbott shall notify NaPro in writing
of Abbott's interest in the Development Opportunity. If Abbott does not deliver
a written notice as contemplated by the preceding sentence, then Abbott shall
have no further rights under this Section 11.3 with respect to the Development
Opportunity.
                  11.3.2 In the event that Abbott delivers to NaPro the written
notice contemplated by the first sentence of Section 11.3.1, NaPro shall
negotiate with Abbott exclusively and in good faith for a period of not less
than ninety (90) days after Abbott delivers to NaPro such written notice. The
ninety (90) day period contemplated by this Section 11.3.2 may be extended by
mutual written agreement of the Parties; provided, however, the failure by
either Party to agree to extend the negotiation period shall not be evidence of
any failure to negotiate in good faith. If the Parties do not reach a written
agreement covering such Development Opportunity during such ninety (90) day
period or longer period if mutually agreed, then NaPro shall have the
opportunity to solicit offers from Third Parties for the Development
Opportunity.
                  11.3.3 In the event that: (a) the ninety (90) day negotiation
period as described in 11.3.2 ends and the Parties do not execute a definitive
agreement covering the Development Opportunity; (b) during the ninety (90) day
negotiation period, Abbott offered in writing economic terms which were rejected
by NaPro ("Abbott's Economic Terms"); and (c) during the Term, NaPro
subsequently solicits and receives a bona fide Third Party offer with respect to
such Development Opportunity; then NaPro shall be free enter into an agreement
with that Third Party regarding the Development Opportunity if the written
economic terms (taken in the aggregate) and as determined by a mutually
acceptable Third Party independent consultant/appraiser knowledgeable in the
area) offered by the Third Party ( "Third Party's Economic Terms") are more
favorable to NaPro (taken in the aggregate and as determined by a mutually

Economic Terms (taken in the aggregate), then Abbott shall have the right for a
period of thirty (30) days to determine whether to accept the Third Party's
Economic Terms as the basis for an arrangement with NaPro with respect to the
Development Opportunity. All determinations as to whether a Third Party's
Economic Terms are more or less favorable than Abbott's Economic Terms shall be
made as provided in Section 11.3.3.1. If at the end of such thirty (30) day
period (or longer if mutually agreed upon by the Parties) Abbott and NaPro have
not executed a definitive agreement after good faith negotiations substantially
on the Third Party's Economic Terms, then Abbott shall have no further rights
with respect to such Development Opportunity. The thirty (30) day period
contemplated by this Section 11.3.3 may be extended by mutual written agreement
by the Parties; provided, however, the failure by either Party to agree to
extend the negotiation period shall not be evidence of any failure to negotiate
in good faith.

Days following the date that NaPro received the formal written offer from the
Third Party containing the Third Party's Economic Terms; or (b) thirty (30)
Business Days prior to the time that NaPro enters into a definitive agreement
with the Third Party regarding the Development Opportunity, outlining the basis
for its determination. If Abbott agrees with NaPro's determination, then the
determination shall be final and binding on the Parties. If Abbott does not
agree with NaPro's determination, then Abbott shall notify NaPro in writing not
later than the close of business on the tenth (10th) Business Day following
NaPro's delivery of the notice specified in the first sentence of this Section
11.3.3.1. If Abbott has not given NaPro the notice contemplated by the preceding

sentence within the time required, then NaPro's determination shall be final and
binding on the Parties. If Abbott desires more information regarding or does not
agree with NaPro's determination, the Parties shall attempt to resolve in good
faith their difference of opinion on the question of whether the Third Party's
Economic Terms (taken in the aggregate) are more or less favorable to NaPro than
Abbott's Economic Terms (taken in the aggregate), for a period of ten (10)
Business Days after Abbott delivers the notice contemplated by the preceding
sentence. If at the end of such ten (10) Business Day period, the Parties still
have a difference of opinion, the Parties shall select a mutually acceptable
Third Party independent appraiser knowledgeable in the area to determine whether
the Third Party's Economic Terms (taken in the aggregate) are more or less
favorable to NaPro than Abbott's Economic Terms (taken in the aggregate). If the
Parties are unable to agree on such an appraiser within ten (10) Business Days
after the end of the ten (10) Business Day period described in the preceding
sentence, then the question of whether the Third Party's Economic Terms (taken
in the aggregate) are more or less favorable to NaPro than Abbott's Economic
Terms (taken in the aggregate) shall be determined by a panel of three Third
Party independent appraisers knowledgeable in the area, one of whom shall be
selected in good faith by NaPro, another of whom shall be selected in good faith
by Abbott, and the third of whom shall be selected by such other two appraisers
or, if such appraisers shall be unable to agree upon a third appraiser within
ten (10) Business Days of the selection date of the second of such two
appraisers, by the Center for Public Resources; provided, that if either party
fails to select its appraiser within ten (10) Business Days after the expiration
of the time period for selecting a single appraiser, then the question of
whether a Third Party's Economic Terms (taken in the aggregate) are more or less
favorable to NaPro than Abbott's Economic Terms (taken in the aggregate) shall
be determined solely by the appraiser selected by the other party. The appraiser
or appraisers appointed pursuant to the foregoing procedure shall be instructed
to determine whether the Third Party's Economic Terms (taken in the aggregate)
are more or less favorable to NaPro than Abbott's Economic Terms (taken

in the aggregate) within fifteen (15) Business Days after the final appointment
of all appraisers, and such determination shall be final and binding upon the
Parties. The procedure described in this Section 11.3.3.1 is the exclusive means
to resolve any dispute as to whether a Third Party's Economic Terms (taken in
the aggregate) are more or less favorable to NaPro than Abbott's Economic Terms
(taken in the aggregate), and neither Party shall have recourse to the
procedures contemplated by Section 16 or any legal process for purposes of
resolving any such dispute.
                  11.3.4 Upon completion of the procedures contemplated by
Section 11.3.3, if NaPro has entered into an agreement covering such Development
Opportunity with a Third Party, then the Territory covered by such Development
Opportunity shall be deemed an Unavailable Territory for purposes of this
Agreement and added to Exhibit F-2 in the manner contemplated by Section 18.6.
                  11.3.5 Notwithstanding the foregoing provisions of this
Section 11.3, if the Development Opportunity concerns Expanded Field Rights,
then the right to refer to and use the Paclitaxel Data in connection with the
Development Opportunity shall be limited to the Expanded Field Rights and shall
not encroach the Field.

                  a written notice
pursuant to Section 11.2, Abbott shall notify NaPro in writing of Abbott's
interest in the Development Opportunity. If Abbott does not deliver a written
notice as contemplated by the preceding sentence, then Abbott shall have no
further rights under this Section 11.4 with respect to the Development
Opportunity.
                  11.4.2 In the event that Abbott delivers to NaPro the written
notice contemplated by the first sentence of Section 11.4.1, NaPro shall
negotiate with Abbott exclusively and in good faith for a period of not less
than ninety (90) days after Abbott delivers to NaPro such written notice. If the

shall have no further rights under this Section 11.4 with respect to such
Development Opportunity. The ninety (90) day period contemplated by this Section
11.4.2 may be extended by mutual written agreement of the Parties; provided,
however, the failure by either Party to agree to extend the negotiation period
shall not be evidence of any failure to negotiate in good faith.
                  11.4.3 In the event that: (a) the ninety (90) day negotiation
period as described in 11.4.2 ends and the Parties do not execute a definitive
agreement covering the Development Opportunity; and (b) during the Term, NaPro
subsequently solicits and receives a bona fide Third Party offer with respect to
such Development Opportunity; then NaPro shall be free enter into an agreement
with that Third Party regarding the Development Opportunity.

Section 11.4.3, if NaPro has entered into an agreement covering such Development
Opportunity with a Third Party, then the territory covered by such Development
Opportunity shall be deemed an Unavailable Territory for purposes of this
Agreement and added to Exhibit F-2 in the manner contemplated by Section 18.6.
                  11.4.5 NaPro shall not use or have the right to reference any

a Third Party under this Section 11.4.
         11.5 Abbott Initiation of Negotiations. If Abbott should have an
interest in and desire to negotiate for any Other Territory Rights and/or
Expanded Field Rights, Abbott will give written notice to NaPro and if NaPro is
interested in discussing an arrangement, such discussions will commence pursuant
to Sections 11.3 or 11.4, as applicable.
         11.6     Certain Obligations Regarding Use of Paclitaxel Data and Joint

assertion or commencement of any Third Party Claim against such Indemnitee with
respect to which an

Indemnifying Party is obligated to provide indemnification under this Agreement,
the Indemnitee will give such Indemnifying Party reasonably prompt written
notice thereof, but in any event not later than ten (10) Business Days after
receipt of such notice of such Third Party Claim. Such notice will describe the
Third Party Claim in reasonable detail, will include copies of all material
written evidence thereof, and will indicate the estimated amount, if reasonably
practicable, of the Indemnifiable Loss that has been or may be sustained by the
Indemnitee. The Indemnifying Party will have the right to participate in, or, by
giving written notice to the Indemnitee, to assume, the defense of any Third
Party Claim at such Indemnifying Party's own expense and by such Indemnifying
Party's own counsel (reasonably satisfactory to the Indemnitee), and the
Indemnitee will cooperate in good faith in such defense.
                  13.1.5 Defense. If, within ten (10) Business Days after giving
notice of a Third Party Claim to an Indemnifying Party pursuant to Section
13.1.3, an Indemnitee receives written notice from the Indemnifying Party that
the Indemnifying Party has elected to assume the defense of such Third Party
Claim as provided in the last sentence of Section 13.1.3, the Indemnifying Party
will not be liable for any legal expenses subsequently incurred by the
Indemnitee in connection with the defense thereof; provided, however, that if
the Indemnifying Party fails to take reasonable steps necessary to defend
diligently such Third Party Claim within ten (10) Business Days after receiving
written notice from the Indemnitee that the Indemnitee believes the Indemnifying
Party has failed to take such steps or if the Indemnifying Party has not
undertaken fully to indemnify the Indemnitee in respect of all Indemnifiable
Losses relating to the matter, the Indemnitee may assume its own defense, and
the Indemnifying Party will be liable for all reasonable costs or expenses paid
or incurred in connection therewith. Without the prior written consent of the
Indemnitee, the Indemnifying Party will not enter into any settlement of any
Third Party Claim which would lead to liability or create any obligation on the
part of the Indemnitee for which the Indemnitee is not entitled to
indemnification hereunder.

                  13.1.6 Indemnifiable Loss Recovery. If the amount of any
Indemnifiable Loss, at any time subsequent to the making of an Indemnity
Payment, is reduced by recovery, settlement, or otherwise under or pursuant to
any insurance coverage, or pursuant to any claim, recovery, settlement, or
payment by or against any other Person, the amount of such reduction, less any
costs, expenses, premiums or taxes incurred in connection therewith will
promptly be repaid by the Indemnitee to the Indemnifying Party. Upon making any
Indemnity Payment the Indemnifying Party will, to the extent of such Indemnity
Payment, be subrogated to all rights of the Indemnitee against any Person that
is not an Affiliate of the Indemnitee in respect of the Indemnifiable Loss to
which the Indemnity Payment related; provided, however, that: (a) the
Indemnifying Party shall then be in compliance with its obligations under this
Agreement in respect of such Indemnifiable Loss; and (b) until the Indemnitee
recovers fully payment of its Indemnifiable Loss, any and all claims of the
Indemnifying Party against any such Person on account of said Indemnity Payment
will be subrogated and subordinated in right of payment to the Indemnitee's
rights against such Person. Without limiting the generality or effect of any
other provision hereof, each such Indemnitee and Indemnifying Party will duly
execute upon request all instruments reasonably necessary to evidence and
perfect the above-described subrogation and subordination rights.
         13.2 Insurance. Beginning on the Effective Date and until the date
which is one day prior to the date of First Commercial Sale, NaPro shall
maintain product liability insurance with an A.M. Best Company rating of at
least A+ with a minimum annual amount of: (a) Five Million Dollars ($5,000,000)
per occurrence; and (b) Ten Million Dollars ($10,000,000) in the aggregate.

Party for any incidental or consequential damages arising out of the terms of
this Agreement.

                        PRODUCT RECALL AND ADVERSE EVENTS
         14.1 Recall Notification and Implementation. Each Party shall promptly
notify the other Party in writing of any facts relating to the advisability of
the recall, destruction or withholding from the market of Bulk Drug or Finished
Product anywhere in the Territory (collectively, "Recall"). If at any time: (a)
any governmental or regulatory authority in the Territory issues a request,
directive or order for a Recall; (b) a court of competent jurisdiction orders a
Recall in the Territory; or (c) Abbott determines, following consultation with
NaPro (except in emergency situations in which there is insufficient time for
such consultation), that a Recall in the Territory is necessary or advisable,
Abbott shall take all appropriate corrective actions to effect the Recall and
NaPro shall provide Abbott with such cooperation in connection with the Recall
as Abbott may reasonably request.
         14.2 Recall Costs and Expenses. Abbott shall bear the costs and
expenses of any Recall in the Territory to the extent such Recall is the result
of any fault or omission attributable to Abbott or its Affiliates, and NaPro
shall bear all costs and expenses of any Recall in the Territory to the extent
such Recall is the result of any fault or omission attributable to NaPro or its
Affiliates.
         14.3 Adverse Events. During the term, each Party shall promptly inform
the other Party of any information it receives or develops regarding the safety

side effects related to the use of the Bulk Drug or Finished Product. To allow
the Parties to comply with the adverse drug experience reporting requirements
for Bulk Drug or Finished Product to the FDA and its counterpart regulatory
agencies in the Territory NaPro shall notify Abbott in writing of any "adverse
drug experience" that is considered "serious" as defined in FDA regulations (21
CFR 314.80) or the comparable regulations of other regulatory agencies in the
Territory, regardless of source, so that Abbott will receive such notice within
three (3) Business Days of NaPro's first having "obtained or otherwise received
such" "adverse drug experience" from "any source", as those terms are defined in
FDA regulations (21 CFR 314.80). Such information shall be communicated by NaPro

         14.4 Complaint Handling. Abbott shall be responsible for addressing and
resolving customer complaints regarding the Finished Product distributed by
Abbott in the Territory, and for answering and responding to any customer
questions with respect to the Finished Product in the Territory; provided,
however, that NaPro shall reasonably cooperate with Abbott to resolve complaints
related to Bulk Drug. Any serious adverse event report or medical complaint
received by Abbott or NaPro from any country in the Territory relating to the
Finished Product shall be promptly investigated by Abbott. NaPro shall notify
Abbott three (3) Business Days after becoming aware of an adverse event or
medical complaint, and provide to Abbott contact information to allow Abbott to

regulatory authority any such report that involves an event that is serious (as
those terms are defined by then applicable FDA or applicable regulatory
authority regulations), but in any event within fifteen (15) calendar days of
receipt (term definition and reporting requirements to be modified to meet then
applicable regulations). Abbott shall prepare adverse event periodic reports in
accordance with FDA or applicable regulatory authority regulations. Abbott shall
be responsible for submission of periodic reports to the FDA or applicable
regulatory authority. Adverse event reports required to be made to regulatory
agencies in other countries shall be handled solely by NaPro, with Abbott
providing necessary supportive information.

(b) twenty (20) years following the Effective Date. The consequences of
termination, whether by expiration of the Term or by earlier termination
pursuant to this Article 15, shall be as set forth in Section 15.6. For the
purposes of this Section 15.1, the term "date of expiration" shall mean the date

full term (including any extension) as granted by the United States Patent and
Trademark Office or the equivalent patent authority in other countries in the

NaPro. Abbott shall be responsible for payment of any milestone payments set
forth in Section 3.1, that have been earned prior to the date of Abbott's notice
of termination.
         15.3 Termination by Either Party for Cause. Either Party shall have the
right, without prejudice to any other rights or remedies available to it, to
terminate this Agreement for cause upon thirty (30) days' written notice to the
other Party in any of the following events:

adjudged bankrupt, applies for judicial or extra-judicial settlement with its
creditors, makes an assignment for the benefit of its creditors, voluntarily
files for bankruptcy or has a receiver or trustee (or the like) in bankruptcy
appointed by reason of its insolvency, or in the event an involuntary bankruptcy
action is filed against the other Party and not dismissed within ninety (90)
days, or if the other Party becomes the subject of liquidation or dissolution
proceedings or otherwise discontinues business.
                  15.3.2 Material Breach. If the other Party commits a Material
Breach of this Agreement and the Party alleged to be in breach fails to either:
(a) cure such Material Breach; or (b) commence dispute resolution proceedings

                            15.3.2.1 with respect to Abbott, a willful failure
by Abbott to pay any: (a) milestone payments pursuant to Section 3.1; (b)
Additional Consideration payments pursuant to Article 4; (c) Development Plan
funding payments that Abbott is obligated to make pursuant to Section 6.2; (d)

                  15.3.3 Notwithstanding anything to the contrary herein, NaPro
may challenge Abbott's failure to comply with its obligations pursuant to
Section 9.3 as a potential Material Breach of the terms of this Agreement only
one (1) time per Sales Year.

         15.5     Termination by Abbott for Cause.
                  15.5.1 Related to Finished Product. If at any time during the
Term: (a) the Development Committee determines that obtaining or maintaining a
Regulatory Approval is not feasible due to any one (1) or more of the following:
(i) documented adverse reactions or other safety issues with the Finished
Product, (ii) the Finished Product's lack of efficacy or limited efficacy, or
(iii) registration is not allowed or approved because of orphan drug status of a
product containing Paclitaxel owned, marketed or sold by a Third Party; (b) the
Finished Product is withdrawn or recalled from the market in any country in the
Territory due to safety issues or adverse events which lead Abbott to conclude
that such safety issues or adverse events could not be alleviated using
commercially reasonable efforts to allow re-entry into the market; (c) the
Finished Product is withdrawn or recalled from the market in any country in the
Territory due to efficacy issues which lead the Development Committee to
conclude that such efficacy issues could not be alleviated using commercially
reasonable efforts to allow re-entry into the market; (d) Regulatory Approval
for at least one Finished Product is not received on or before [THIS PORTION HAS
BEEN REDACTED.] ; or (e) Abbott withdraws any Application of Regulatory Approval
for a Finished Product due to documented adverse reactions or other safety
issues which lead Abbott (in consultation with the Development Committee) to
conclude that such adverse reactions and safety issues could not be alleviated
using commercially reasonable efforts and that re-submission of another
Application for Regulatory Approval would not be reasonably feasible, then

may, at its option, terminate this Agreement upon thirty (30) days' prior
written notice to NaPro. Abbott may, at its option, exercise its right of
termination under this Section 15.5.1 on a country-by-country basis, and, if
Abbott does so, Abbott's termination notice shall specify the country or
countries of the Territory affected. Upon such termination, the definition of
the term "Territory" shall be deemed thereby to have been amended to exclude
that country or area, and NaPro shall have the right to develop products
containing Paclitaxel for manufacture, use and sale in that country or area and
the right to use and reference Paclitaxel Data without any of the limitations
imposed upon NaPro by Article 11 of this Agreement.
                  15.5.2 Related to Patent Invalidation. In the event that one
(1) or more claims of an issued and unexpired NaPro Patent (in the case of the
NaPro Formulated Product) or Abbott Patent (in the case of the Abbott Formulated
Product) or a patent included in Joint Patent Rights or any patent in-licensed
from a Third Party as contemplated in Section 2.3 has been held unenforceable,
unpatentable or invalid by a decision of a court or governmental agency of
competent jurisdiction that is unappealable or unappealed within the time
allowed for appeal, or has been admitted by NaPro (in the case of a NaPro
Patent) or Abbott (in the case of an Abbott Patent) to be invalid or
unenforceable through reissue, disclaimer, abandonment or otherwise, and the
result of such invalidation(s) is that the manufacture, sale or Commercial Use
of no Finished Product(s) in accordance with the actual or anticipated NDA
approval is covered by any Valid Claim of a NaPro Patent (in the case of the
NaPro Formulated Product) or Abbott Patent (in the case of the Abbott Formulated
Product) or a patent included in Joint Patent Rights or any patent in-licensed
from a Third Party as contemplated in Section 2.3, then Abbott may, at its
option, terminate this Agreement upon thirty (30) days' prior written notice to
NaPro.
                  15.5.3 Related to Breach of Representation or Warranty. In the
event that NaPro breaches a representation or warranty made by NaPro in Article
12, which breach has a material adverse effect on the Development Program or the
development, marketing, or

                         ALTERNATIVE DISPUTE RESOLUTION
         All disputes arising out of or in connection with this Agreement
(except those involving actions commenced by or involving Third Parties and
affecting or involving only one of the Parties) shall be resolved with the
following mechanism:
         16.1 Attempted Amicable Resolution. The Parties shall promptly give
each other written notice of any disputes requiring resolution hereunder, which
written notice shall specify the Section(s) of this Agreement the other Party is
alleged to have breached or pursuant to which there is a dispute and shall
briefly state the initiating Party's claims. The Parties shall use reasonable
efforts to resolve any such disputes in an amicable manner.
         Any disputes arising in connection with this Agreement which cannot be
resolved in an amicable manner by representatives of the Parties shall be
referred, not later than thirty (30) days after initiation of dispute resolution
proceedings under this Section 16.1, to the following corporate officers of the
Parties for resolution:

         For Abbott:
         President, Hospital Products Division (or his or her designee)

         For NaPro:
         CEO (or his or her designee)

         Such officers (or their designees) shall attempt to resolve the dispute
and shall communicate with each other by facsimile or telephone or in personal
meetings in an effort to resolve the dispute.
         16.2 Alternate Dispute Resolution. Any disputes arising in connection
with this Agreement which cannot be resolved by the Parties within forty-five
(45) days after initiation of dispute resolution proceedings under Section 16.1
shall be finally settled by binding Alternate Dispute Resolution in accordance
with the procedures set forth in Exhibit G ("ADR"); provided, however, that an
assertion by NaPro that Abbott is in Material Breach of Abbott's obligations
pursuant to Section 9.3 shall not be more than one (1) time in any Sales Year.
Judgment upon any award rendered by the neutral in such proceedings may be
issued and enforced by any court having competent jurisdiction.
         16.3 ADR Ruling. The neutral in any ADR proceeding under Section 16.2
relating to an alleged breach of the Agreement by either Party shall determine
and advise the Parties in writing:
                  16.3.1 whether either Party has committed a breach of any of
its obligations under this Agreement; and
                  16.3.2   if either Party has committed a breach;
                           16.3.2.1 whether such breach is a Material Breach or
a breach other
than a Material Breach; and
                           16.3.2.1 the appropriate remedy for any such breach
pursuant to Section 16.4.

         16.4 ADR Remedies. The neutral in any ADR proceeding under Section 16.2
shall have the authority to award the non-breaching Party the following relief
and any other relief as set forth in Article 15:
                  16.4.1 For a Material Breach, an award of damages and/or
equitable relief and/or termination of this Agreement in whole or in part
(including the termination of any licenses granted to the breaching Party,
whether in whole or in part, in the Territory or on a country-by-country basis);
and
                  16.4.2 For a breach other than a Material Breach, an award of
damages and/or equitable relief, but not termination of this Agreement in whole
or in part or any licenses granted to the breaching Party under this Agreement.
         16.5 Effect on Time Periods in this Agreement. If there is a dispute
regarding the exercise of any right, or the performance of any obligation, under
this Agreement, and this Agreement provides that such right may or must be
exercised, or that such performance must be rendered, by a specified date or
within a specified period of time, then the applicable date shall be extended,
and the applicable time period shall be tolled, without prejudice to either
Party pending the outcome of the ADR proceeding.
         16.6 Exclusivity. The ADR process contemplated by this Article 16 shall
be the exclusive means for either Party to this Agreement to seek resolution of
any dispute or adjudication of alleged breach arising out of, relating to, or
connected with this Agreement, except that either Party may bring an action
before a competent court for the adoption of provisional or protective measures
or equitable relief. The pendency of a matter referred to ADR shall not excuse
any Party for performance under this Agreement, it being understood that such
performance is without prejudice to the Party's position in the dispute
resolution process.
         16.7 Express Remedies. If this Agreement provides for an express remedy
in the event of a breach or an express outcome upon the occurrence of certain
events, the neutral in the ADR proceeding shall not have the authority to award
a different remedy or mandate a

limit the neutral's ability to award a remedy or mandate an outcome that is in
addition to the express remedy or outcome provided in this Agreement.

an IND, or Application(s) for Regulatory Approval for the Finished Product(s).
                  17.2.2 In the case of NaPro, Abbott Confidential Information
may be provided to: (a) regulatory authorities in connection with any

purpose of obtaining an IND or Application for Regulatory Approval for the
Finished Product, subject to suitable confidentiality undertakings.
                  17.2.3 In the case of Abbott, NaPro Confidential Information
may be used and provided to Third Parties to the extent reasonably necessary for
Abbott to perform its obligations and/or exercise its rights under this
Agreement, including but not limited to, performing research and development

agents which incorporate the other Party's Confidential Information, however
only to the extent of the Confidential Information or the other Party. One (1)
copy of such documents containing Confidential Information so returned or
destroyed may be retained by each Party as part of its permanent records solely
for purposes of maintaining a record of Confidential Information returned or

         17.5 Publicity and Announcements. The Parties agree that, upon
execution of this Agreement, a press release approved by both parties will be

"Originating Party") shall: (a) originate any publicity, news release or other
public announcement, written or oral, whether to the public press, stockholders
or otherwise, relating to this Agreement, matters relevant to this Agreement,
amendments hereto or performance by the Parties hereunder or the Bulk Drug or
Finished Product; or (b) use the name of the other Party in any publicity, news
release or other public announcement, except (i) with the prior written consent,
review and approval of the other Party (a "Reviewing Party") in which case the

Receiving Party (which, in the case of Abbott, shall be its Manager of Public
Affairs, Hospital Products Division, and in the case of NaPro, shall be its
General Counsel) not less than three (3) Business Days prior to its use or
publication, or (ii) as required by written state or federal securities law or

in the case of (ii), the Originating Party shall be free to issue such release
without comment from the Reviewing Party.

         18.1 Force Majeure. Except as set forth in Section 8.7.2, in the event
that either Party's performance of its obligations under this Agreement shall be
prevented by any cause beyond its reasonable control, including without
limitation acts of God, acts of government, shortage of material, accident,
fire, delay or destruction of means of transport or other disaster, provided
that the affected Party shall have used its reasonable best efforts to avoid

or remove the cause of such nonperformance and to minimize the duration and
negative affect of such nonperformance, then such affected Party's performance
shall be excused and the time for performance shall be extended for the period
of delay or inability to perform due to such occurrence. The affected Party
shall continue performance under this Agreement using its best efforts as soon
as such cause is removed.
         18.2 Severability. In the event that any provision of this Agreement
shall be held to be unenforceable, invalid or in contravention of applicable
law, such provision shall be of no effect, the remaining portions of this
Agreement shall continue in full force and effect, and the parties shall
negotiate in good faith to replace such provision with a provision which effects
to the extent possible the original intent of such provision.
         18.3 Assignment/Third Parties. Neither Party shall assign any rights or
obligations under this Agreement to Third Parties without the prior written
consent of other Party. Notwithstanding the foregoing, (a) Abbott may assign
this Agreement or any of its rights or obligations under this Agreement to one
or more of its Affiliates (provided that Abbott guarantees the performance of
such assigned rights or obligations by the Affiliate and such Affiliate shall
become a party to this Agreement) without NaPro's prior written consent, (b)
Abbott may engage a Third Party to assist Abbott in marketing, sales and
distribution activities for the Finished Product, provided that Abbott continues
to market and sell the Finished Product as well, (c) Abbott may perform any one
or more of its obligations (other than marketing, sales and distribution
activities, which is addressed in Subsection (b)) set forth in this Agreement by
appointing Third Parties to perform some or all of Abbott's obligations
hereunder on Abbott's behalf and in Abbott's name, provided that NaPro has given
Abbott its prior written consent to each such appointment, which consent shall
not be unreasonably withheld or delayed, (d) either Party may assign this
Agreement and all of its rights and obligations under this Agreement to any
successor (whether by merger, sale of assets, or otherwise) to all of the
respective Party's business related to this Agreement, and (e) subject to
approval of the Development Committee, NaPro may engage one or more

activities under the Development Program.
         18.4 Relationship of Parties. Nothing contained in this Agreement shall

of employee or agent or joint venturer or legal representative of the other
Party. It is hereby expressly agreed and acknowledged that each of the parties
hereto is an independent contracting Party which does not have the authority or
power for or on behalf of the other Party hereto to enter into any contract to
incur debts, to accept money, to assume any obligations or to make any
warranties or representations whatsoever.
         18.5 Waiver. The waiver by either Party of a breach or a default of any
provision of this Agreement by the other Party shall not be construed as a
waiver of any succeeding breach of the same or any other provisions, nor shall
any delay or omission on the part of either Party to exercise or avail itself of
any right, power or privilege that it has, or may have hereunder, operate as a
waiver of any right, power or privilege by such Party.
         18.6 Contract Modification. Any modification, alteration, change or
variation in any provision of this Agreement shall be only made in a writing
that refers to this Agreement executed by both parties.
         18.7 Notices. Notices by one Party to the other shall be in writing

                                                                  EXECUTION COPY


                            (i) Representations and Warranties. The
representations and warranties of Abbott set forth in this Agreement shall be
true and correct in all material respects as of the date of this Agreement and
as if made at and as of each Additional Closing Date and NaPro shall have
received a certificate or certificates signed by a responsible officer of Abbott
to such effect.
                            (ii) Performance of Obligations of Abbott. Abbott
shall have performed in all material respects all obligations required to be
performed by it under this Agreement prior to each Additional Closing Date and
NaPro shall have received a certificate or certificates signed by a responsible
officer of Abbott to such effect.
                            (iii) Regulatory Approvals, etc. Any required
regulatory approvals and/or associated waiting periods applicable to the sale
and purchase of the Additional Shares shall have been obtained and/or expired.
                            (iv) Payment. Abbott shall have delivered to NaPro
the applicable purchase price for the First Additional Shares or the Second
Additional Shares, as the case may be.

                  (e) Certain Adjustments. If NaPro at any time effects a
subdivision or combination of the outstanding Common Stock, the purchase price
for the Additional Shares shall be decreased, in the case of a subdivision, or
increased, in the case of a combination, in the same proportions as the Common
Stock is subdivided or combined, in each case effective automatically upon, and
simultaneously with, the effectiveness of the subdivision or combination which
gives rise to the adjustment. If NaPro at any time pays a dividend, or makes any
other distribution, to holders of Common Stock payable in shares of Common
Stock, or fixes a record date for the determination of holders of Common Stock
entitled to receive a dividend or other distribution payable in shares of Common
Stock, the purchase price for the Additional Shares shall be adjusted by
multiplying it by a fraction:
                           (i) the numerator of which shall be the total number
         of shares of Common Stock outstanding immediately prior to such
         dividend or distribution; and



                                       7

<PAGE>



                            (ii) the denominator of which shall be the total
number of shares of Common Stock outstanding immediately after such dividend or
distribution (plus, if NaPro paid cash instead of fractional shares otherwise
issuable in such dividend or distribution, the number of additional shares which
would have been outstanding had NaPro issued fractional shares instead of cash);
in each case effective automatically as of the date NaPro shall take a record of
the holders of its Common Stock for the purpose of receiving such dividend or
distribution (or if no such record is taken, as of the effectiveness of such
dividend or distribution). Whenever the purchase price for the Additional Shares
shall be adjusted, NaPro shall make a certificate signed by a corporate officer
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated,
and the purchase price for the Additional Shares after giving effect to such
adjustment, and shall cause a copy of such certificate to be mailed (by first
class mail postage prepaid) to Abbott promptly after each adjustment.

         3. Representations and Warranties of NaPro. NaPro represents and
warrants to Abbott that, as of the date of this Agreement:

validly existing, and in good standing under the laws of the State of Delaware,

existing and in good standing under the laws of its state or county of
incorporation. NaPro and each of its subsidiaries has all requisite power and
authority to own and operate its properties and to carry on its business as now
conducted and as presently proposed to be conducted, and is duly licensed or
qualified and is in good standing as a foreign corporation in each jurisdiction
wherein the nature of the business transacted by it or the nature of the
property owned or leased by it makes such licensing or qualification necessary
or advisable, except where the failure to be so licensed or qualified would not
have a material adverse effect on NaPro and its subsidiaries taken as a whole.
NaPro has the corporate power and authority to execute and deliver this
Agreement, and to perform its obligations under this Agreement, including the
issuance, sale and delivery of the Shares. All

corporate action required to be taken by NaPro to authorize the execution,
delivery and performance of this Agreement, including (i) the issuance, sale and
delivery of the Shares and (ii) the approval of any transaction or series of
transactions authorized or permitted under Section 2 of this Agreement in which

rule or regulation applicable to NaPro or its subsidiaries, except in the case
of clauses (ii), (iii) and (iv) for such violations, conflicts, consents,
defaults or accelerations that would not affect the enforceability of this
Agreement in accordance with its terms or otherwise have a material adverse
effect on the purchase or sale of the Shares. Assuming the truth of the
representations and warranties set forth in Section 4 of this Agreement, no
consent, approval, order or authorization of, or registration, qualification,
designation, declaration or filing with any court, administrative agency or
commission or other governmental authority or other Person is or will be
required by, or with respect to, NaPro in connection with the execution and
delivery of this Agreement, the issuance, offer and sale of the Shares or the
consummation by NaPro of the transactions

         securities laws or an applicable exemption from such registration
         requirements.
                           (iii) The sale of the Shares is not subject to any

         Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed
         by NaPro with the SEC since January 1, 1995 (including all amendments
         to each of the foregoing, the forms, reports and other documents
         referred to in clauses (A) through (C) being referred to in this
         Agreement, collectively, as the "NaPro Disclosure Documents"). The

         with the Securities Act or the Securities Exchange Act, as the case may
         be, and the rules and regulations thereunder; and (y) did not at the
         time they were filed with the SEC contain any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary in order to make the statements made therein, in
         the light of the circumstances under which they were made, not
         misleading.
                           (ii) Each of the consolidated financial statements
         (including any notes thereto) contained in the Annual Reports on Form

         31, 1996, December 31, 1997, and December 31, 1998, was prepared in

         its consolidated subsidiaries had any material liabilities or
         obligations, secured or unsecured (whether accrued, absolute,
         contingent or otherwise). For purposes of the preceding sentence, a
         "material liability or obligation" is one that exceeds 5% of NaPro's
         consolidated assets as of December 31, 1998.
                  (e) Absence of Certain Changes. Since March 31, 1999, and

warrants to NaPro that, as of the date of this Agreement:
                  (a) Authority of Abbott. Abbott is a corporation duly
organized, validly existing, and in good standing under the laws of the State of
Illinois. Abbott has the corporate power and authority to execute and deliver
this Agreement, and to perform its obligations under this Agreement. All
corporate action required to be taken by Abbott to authorize the execution,
delivery and performance of this Agreement has been duly taken.
                  (b) Validity. This Agreement constitutes the valid and legally
binding obligation of Abbott, enforceable against Abbott in accordance its terms
and conditions. The execution and delivery of this Agreement and consummation of
the transactions contemplated by this Agreement by Abbott is not prohibited by,

material contract, agreement or other instrument to which Abbott is a party or
by which Abbott is bound; (iii) any order, writ, injunction, decree or judgment
of any court or governmental agency applicable to Abbott; or (iv) any law, rule
or regulation applicable to Abbott.
                  (c) Resale. Abbott is acquiring the Shares under this
Agreement for its own account solely for the purpose of investment and not with
a view to, or for offer or sale in connection with, any distribution thereof in
violation of the Securities Act. Abbott has such knowledge and experience in
financial and business matters as to be capable of evaluating the risks and
merits of an investment in the Shares and is able to bear the economic risk of
such investment. Abbott acknowledges and agrees that



                                       14

<PAGE>


                                                                  EXECUTION COPY

none of the Shares has been registered under the Securities Act and that such
Shares may be sold or disposed of in the absence of such registration only
pursuant to an exemption from such registration and in accordance with the terms
of this Agreement and the Securities Act and that NaPro's transfer agent is
authorized to place stop transfer instructions on the NaPro's stock transfer
records and may refuse to transfer any Shares not transferred in compliance with
this Agreement or the Securities Act or in compliance with the restrictions on
transfer set forth in Section 13(m) and 13(n).
                  (d) Receipt of Information. Abbott has experience in
evaluating and investing in companies in the same industry as NaPro and is able
to assess the relative merits and risks of an investment in NaPro and to sustain
a total loss on such investment. Abbott further represents that it has had an
opportunity to ask questions and receive answers from NaPro regarding the terms
and conditions of the offering of the Shares and the business, properties,
prospects and financial condition of NaPro and its subsidiaries and to obtain
additional information it considers necessary or appropriate for deciding
whether to purchase the Shares. The foregoing, however, does not limit or modify
the representations and warranties of NaPro in Section 3 of this Agreement or
the right of Abbott to rely thereon.
         5.       Registration Rights.
                  (a) Demand Registration Rights. Upon the earlier of: (i) the
date of the filing by NaPro of an NDA for a Finished Product with the FDA; and
(ii) two (2) years after the date of this Agreement, upon the written request of
Abbott, NaPro, to the extent permitted by law and subject to the terms of this
Agreement, shall register any Registrable Shares held by Abbott that Abbott
requests to be registered pursuant to an effective registration statement under
the Securities Act (a "Registration"); provided, however, that any such request
shall be for at least 50% of the Registrable Shares held by Abbott (a
Registration pursuant to this Section 5(a) is referred to in this Agreement as a
"Demand Registration"). Abbott's request for a Demand Registration shall specify
the number of Registrable Shares requested to be registered and whether such
Shares are Initial Shares, First Additional Shares or Second Additional Shares
or a combination thereof. Within ten (10) Business Days after receipt of any



                                       15

<PAGE>



such request, NaPro will give written notice of such requested Registration to
holders of Registrable Securities and will include in such Registration all
Registrable Securities with respect to which NaPro has received written requests
for inclusion therein within ten (10) Business Days after the receipt of NaPro's
notice; provided, however, that if the Demand Registration relates to an
underwritten offering and the managing underwriter shall advise NaPro or Abbott
that, in its judgment, the number of shares proposed to be included in such
offering should be limited, then NaPro shall promptly so advise each holder of
Registrable Securities, and such Registrable Securities shall be excluded from
the Demand Registration and offering prior to excluding any Registrable Shares
held by Abbott. If the offering to be covered by the Demand Registration is an
underwritten offering, Abbott shall have the right to select one legal counsel
and an investment banker or bankers and manager or managers to administer the
offering, which counsel, investment banker or bankers or manager or managers
shall be reasonably satisfactory to NaPro.
                  (b) Conditions to Demand Registration. NaPro may delay any
Demand Registration requested pursuant to Section 5(a): (i) for a single period
of time not exceeding ninety (90) days (which cannot be extended), if NaPro's
Board of Directors shall determine in good faith that any such Registration
would adversely affect a material financing, acquisition, disposition of assets
or stock, merger or other comparable transaction or would require NaPro to make
public disclosure of information the public disclosure of which would have a
material adverse effect on NaPro, and a certificate to that effect shall be
signed on behalf of NaPro's Board of Directors and delivered to Abbott; or (ii)
if NaPro determines to initiate a registered primary public offering of its
securities in a registered public offering (a "Primary Offering"), in which case
NaPro shall so notify Abbott within ten (10) Business Days of receiving Abbott's
request for a Demand Registration and the delay of the Demand Registration may
not exceed ninety (90) days from the date notice of NaPro's determination to
initiate the Primary Offering is given to Abbott; provided, however, that in the
event the Primary Offering is declared effective by the SEC within such ninety
(90)-day period, the permitted delay may be extended, but in no event shall the
delay exceed one hundred twenty (120) days from the date the Primary Offering is
declared effective.

NaPro may exercise its right to delay a Demand Registration pursuant to clause
(ii) of this Section 5(b) only once. If a Demand Registration is delayed
pursuant to clause (ii) of this Section 5(b), then pursuant to Section 5(c)
Abbott may request inclusion in the Primary Offering of all the Registrable
Shares that were included in its request for the Demand Registration. If: (i)
Abbott requests that such Registrable Shares be so included in the Primary
Offering; and (ii) the number of Registrable Shares sold by Abbott in connection
with the Primary Offering is 75% or more of the number of Registrable Shares
sought by Abbott to be included, then Abbott shall be deemed to have used a
Demand Registration. For the avoidance of doubt, however, if the number of
Registrable Shares sold by Abbott in connection with the Primary Offering is
less than 75% of the number of Registrable Shares sought by Abbott to be
included, then Abbott shall not be deemed to have used a Demand Registration.
                  (c) Piggyback Registration. If at any time, and from time to
time, NaPro proposes to register any of its Common Stock or other securities
under the Securities Act (other than pursuant to Section 5(a)), NaPro shall
promptly give notice to Abbott of its intention to do so. Upon the written
request of Abbott, given within fifteen (15) Business Days after receipt of any
such notice from NaPro, NaPro shall in each instance use its best efforts to
cause the number of Shares requested by Abbott to be registered under the
Securities Act and registered or qualified under any state securities law
provided, however, that the obligation to give such notice and to use such best
efforts shall not apply to any registration (a) on: Form S-8 (or any successor
form); (b) in connection with dividend reinvestment plans or rights offering, or
(c) for the purpose of offering registered securities to another business entity
or the shareholders of such entity in connection with the acquisition of assets
or capital stock of such entity or in connection with a merger, consolidation,
combination or similar transaction with such entity (the Registration pursuant
to this Section 5(c) is referred to in this Agreement as a "Piggyback
Registration"). In the event the managing underwriter of an underwritten
offering or, in the case of any offering that is not underwritten, a recognized
investment banking firm shall advise NaPro in writing (and NaPro shall in each
case so advise Abbott and each holder of Registrable Securities requesting
registration of such



                                       17

advice in writing) that, market factors (including, without limitation, the
aggregate number of shares requested to be registered, the general condition of
the market, and the status of the persons proposing to sell securities pursuant
to the registration) require a limitation of the number of shares to be
underwritten, then NaPro will include in such registration, to the extent of the
number and type of securities which NaPro is so advised can be sold in (or
during the time of) such offering first, all securities of NaPro proposed by
NaPro to be sold for its own account, or, in the case of a secondary offering
made pursuant to demand registration rights granted to any Person other than
Abbott, all securities of NaPro that such Person proposes to sell; second, all
Registrable Securities that are entitled to piggyback registration rights under
agreements with NaPro in existence on the date of this Agreement, which
agreements provide, as of the date hereof, that such piggyback registration
rights shall have priority over the piggyback registration rights granted to
Abbott under this Agreement third, such Registrable Shares requested to be
included in such registration pursuant to this Agreement and Registrable
Securities that are entitled to piggyback registration rights under agreements
with NaPro in existence on the date of this Agreement, which agreements provide,
as of the date of this Agreement, that such piggyback registration rights shall
rank equally with the registration rights granted to Abbott under this
Agreement, allocated pro rata based on the number of shares of Common Stock
owned by such holders; and fourth, all other securities of NaPro that are not
covered by one of the foregoing clauses.

                                                                  EXECUTION COPY

                  (d) Expenses. NaPro shall pay all expenses in connection with
the first Demand Registration and each Piggyback Registration and Primary
Offering (which, for purposes of this Section 5(d) and Section 5(e) shall
include any qualifications, notifications and exemptions) other than
underwriting discounts and commissions attributable to the Registrable Shares
and the fees and expenses of Abbott's counsel, and Abbott shall pay all expenses
in connection with all other Demand Registrations (which, for purposes of this
Section 5(d) and Section 5(e) shall include any qualifications, notifications
and exemptions). Notwithstanding the preceding sentence, if: (i) Abbott had
requested a Demand Registration; (ii) that Demand Registration was delayed
pursuant to Section 5(b)(ii); (iii) Abbott exercised its rights under Section
5(c) to have the Registrable Shares covered by the delayed Demand Registration
in the Primary Offering; (iv) as a result of the number of Registrable Shares
sold in connection with the Primary Offering Abbott was deemed not to have used
a Demand Registration; and (v) the number of Registrable Shares sold by Abbott
in connection with the Primary Offering was more than 50% of the Registrable
Shares sought by Abbott to have included, then NaPro shall no longer be
obligated to pay expenses in connection with a subsequent Demand Registration.
                  (e) Indemnification. In connection with any Registration under
Sections 5(a) or 5(c), NaPro shall indemnify Abbott, its directors, officers,
employees and agents, and each Person, if any, who controls Abbott within the
meaning of the Securities Act or the Securities Exchange Act, against all
losses, claims, damages, liabilities and expenses (including reasonable fees and
disbursements of counsel, and costs of investigation) arising out of: (i) any
untrue, or alleged untrue, statement of a material fact contained in any
registration statement or prospectus or notification or offering circular (and
as amended or supplemented if NaPro shall have furnished any amendments or
supplements) or any preliminary prospectus; (ii) any omission, or alleged
omission, to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they are made, not misleading; or (iii) any violation or alleged violation
by NaPro of the Securities Act, the Securities Exchange Act, any state blue sky
or securities laws or any rule or regulation thereunder;



                                       19

<PAGE>



except insofar as such losses, claims, damages, liabilities or expenses arise
out of any untrue statement or alleged untrue statement or omissions based upon
information furnished in writing to NaPro by Abbott or, in the case of an
underwritten offering by the underwriter for Abbott, expressly for use in such
registration statement or prospectus, and NaPro and each officer, director and
controlling person of NaPro shall be indemnified by Abbott for all such losses,
claims, damages, liabilities and expenses arising out of any untrue, or alleged
untrue, statement or omission, or alleged omission, to the extent (and only to
the extent) such untrue or alleged untrue statement or omission, or alleged
omission, is included by NaPro in such registration statement or prospectus in
reliance upon and in conformity with information furnished in writing to NaPro
by Abbott expressly for any such use provided that Abbott's indemnification
obligations shall be several and not joint and several with any other Person.
                  Promptly upon receipt by an indemnified party of notice of the
commencement of any action against such indemnified party in respect of which
indemnity or reimbursement may be sought against any indemnifying party under
this Section 5(e), the indemnified party shall notify the indemnifying party in
writing of the commencement of such action, but the failure so to notify the
indemnifying party shall not relieve it of any liability which it may have to
any indemnified party otherwise than under this Section 5(e). In case notice of
commencement of any such action shall be given to the indemnifying party as
above provided, the indemnifying party shall be entitled to participate in and,
to the extent it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense of such action at its own expense, with counsel
chosen by it and satisfactory to such indemnified party. The indemnified party
shall have the right to employ separate counsel in any such action and
participate in the defense of such action, but the fees and expenses of such
counsel (other than reasonable costs of investigation) shall be paid by the
indemnified party unless the indemnifying party either agrees to pay the same or
fails to assume the defense of such action with counsel satisfactory to the
indemnified party or unless, in the reasonable judgement of such indemnified
party, a conflict of interest may exist between such indemnified party and
indemnifying party. No indemnifying party who has assumed the defense of an
action pursuant to this Section 5(e) shall be liable for any settlement entered
into without

<PAGE>


                                                                  EXECUTION COPY


its consent, which consent shall not be unreasonably withheld. If the
indemnification provided for in this Section 5(e) is held by a court of
competent jurisdiction to be unavailable to an indemnified party with respect to
any loss, liability, claim, damage or expense referred to herein, then the
indemnifying party, in lieu of indemnifying such indemnified party hereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage or expense in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other hand in connection with the
statements or omissions which resulted in such loss, liability, claim, damage or
expense as well as any other relevant equitable considerations. The relevant
fault of the indemnifying party and the indemnified party shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission to state a material fact relates to
information supplied by the indemnifying party or by the indemnified party and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The provisions hereof shall
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any director, officer, employee, agent or
controlling person thereof, and shall survive the transfer of securities and the
termination of this Agreement.
                  (f)      Provisions Applicable to all Registrations.
                           (i) NaPro shall prepare and file a registration
         statement under the Securities Act and use its best efforts to cause
         such registration statement to become effective as soon as practicable
         following receipt of Abbott's request for a Demand Registration.
         Notwithstanding the foregoing, if NaPro shall fail to cause such
         registration statement to become effective within one hundred twenty
         (120) calendar days following the initial filing of the registration
         statement with the SEC, NaPro's failure shall not be deemed a breach of
         this Section 5(f), provided that NaPro used its best efforts during
         such one hundred twenty-day (120) period.



                                       21

<PAGE>



                           (ii) NaPro shall prepare and file with the SEC such
         amendments (including post-effective amendments) and supplements to the
         registration statement and the prospectus used in connection with the
         registration statement as may be necessary to keep the registration
         statement effective at all times until the earlier of nine (9) months
         after the initial effective date of the registration statement or until
         Abbott shall have given written notice that it has completed the
         distribution of the Registrable Shares thereunder (the "Registration
         Period"), and, during the Registration Period, comply with the
         provisions of the Securities Act with respect to the disposition of all
         securities covered by the registration statement until such time as all
         of such securities have been disposed of in accordance with the
         intended methods of disposition by the seller or sellers thereof as set
         forth in the registration statement. Notwithstanding the foregoing, if
         for any reason NaPro advises Abbott that Abbott's use of the Demand
         Registration to sell Shares should be suspended and Abbott complies
         with such advice, then the Registration Period shall be extended by the
         aggregate number of days of such suspension.
                           (iii) NaPro shall furnish to Abbott (and Abbott's
         legal counsel designated pursuant to Section 5(f)(vii)): (A) promptly
         after the registration statement is prepared and publicly distributed
         and filed with the SEC, one copy of the registration statement and any
         amendment thereto, each preliminary prospectus and prospectus and each
         amendment and supplement thereto; and (B) such number of copies of a
         prospectus (including a preliminary prospectus) and all amendments and
         supplements thereto and such other documents as Abbott may reasonably
         request in order to facilitate the disposition of the Registrable
         Shares covered by the registration statement and owned by such Abbott.
         NaPro shall immediately notify Abbott by facsimile of the effectiveness
         of the registration statement or any post-effective amendment.
                           (iv) NaPro shall use its best efforts to: (A)
         register and qualify the Registrable Shares covered by the registration
         statement under such other securities or "blue sky" laws of such
         jurisdictions in the United States as Abbott reasonably requests; (B)
         prepare and file in those jurisdictions such amendments (including
         post-effective amendments) and supplements



                                       22

                                                                  EXECUTION COPY


         to such registrations and qualifications as may be necessary to
         maintain the effectiveness thereof during the Registration Period; (C)
         take such other actions as may be reasonably necessary to maintain such
         registrations and qualifications in effect at all times during the
         Registration Period; and (D) take all other actions reasonably
         necessary or advisable to qualify the Registrable Securities for sale
         in such jurisdictions provided, however, that NaPro shall not be
         required in connection therewith or as a condition thereto to: (x)
         qualify to do business in any jurisdiction where it would not otherwise
         be required to qualify but for this Section 5(f)(iv); (y) subject
         itself to general taxation in any such jurisdiction; or (z) file a
         general consent to service of process in any such jurisdiction or
         otherwise take any action that would subject it to the general
         jurisdiction of the courts of any jurisdiction in which it would not
         otherwise be so subject.
                           (v) As promptly as practicable after becoming aware
         of such event, NaPro shall notify Abbott of the happening of any event
         of which NaPro has Knowledge as a result of which the prospectus
         included in the registration statement, as then in effect, includes an
         untrue statement of a material fact or omits to state a material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading, and, at NaPro's expense, NaPro shall promptly prepare a
         supplement to the prospectus or amendment to the registration statement
         to correct such untrue statement or omission and use its best efforts
         to cause any such amendment to become effective under the Securities
         Act, and deliver such number of copies of such supplement or amendment
         to Abbott as such Abbott may reasonably request.
                           (vi) NaPro shall use its best efforts to prevent the
         issuance of any stop order or other suspension of effectiveness of the
         registration statement and any similar order of suspension by any state
         securities commission or similar Person, and, if such an order is
         issued or suspension imposed, to obtain the withdrawal of such order or
         suspension at the earliest



                                       23

<PAGE>



         possible moment and to notify Abbott (or, in the event of an
         underwritten offering, the managing underwriters) of the issuance of
         such order or suspension and the resolution thereof.
                           (vii) NaPro shall permit a single firm of legal
         counsel designated by Abbott to review the registration statement and
         all amendments and supplements thereto (as well as all requests for
         acceleration of effectiveness thereof) a reasonable period of time
         prior to their filing with the SEC, and shall not file any document in
         a form to which such counsel reasonably objects and will not request
         acceleration of the registration statement without prior notice to such
         counsel. The sections of the registration statement covering
         information with respect to Abbott, Abbott's beneficial ownership of
         securities of NaPro or Abbott's intended method of disposition of
         Registrable Securities shall conform to the information provided to
         NaPro by Abbott.
                           (viii) NaPro shall otherwise use its best efforts to
         comply with all applicable rules and regulations of the SEC, and make
         generally available to its security holders as soon as reasonably
         practical, an earnings statement (in form complying with the provisions
         of Section 11(a) of the Securities Act and Rule 158 under the
         Securities Act) covering a period of at least twelve (12) months
         beginning with the first day of NaPro's first full calendar quarter
         following the date the registration statement is declared effective by
         the SEC (the "Effective Date").
                           (ix) NaPro shall make available for inspection, at
         the offices where normally kept and during reasonable business hours,
         by: (A) Abbott; (B) any underwriter participating in any disposition
         pursuant to the registration statement; (C) any firm of legal counsel
         and any firm of accountants or other agents retained by Abbott; and (D)
         one firm of legal counsel retained by all such underwriters
         (collectively, the "Inspectors"), all pertinent financial and other
         records, corporate documents and properties of NaPro (collectively, the
         "Records"), as shall be reasonably requested by such person as being
         necessary in the reasonable opinion of such person to conduct a
         reasonable investigation within the meaning of the Securities Act in
         connection with such registration statement, and cause NaPro's
         officers, directors and employees to supply all information which any
         Inspector may reasonably request for purposes of such due diligence;



                                       24

<PAGE>

                                                                  EXECUTION COPY

         provided, however, that each Inspector shall hold in confidence and
         shall not make any disclosure (except to Abbott (subject to the
         limitations set forth in the last sentence of this subsection) or
         agents of NaPro) of any Record designated by NaPro in writing as
         confidential (the "Confidential Records"), unless: (x) the disclosure
         of such Confidential Records is necessary in connection with the
         Inspectors' or Abbott' assertion of any claims or actions or with their
         establishment of any defense in any pending administrative or judicial
         action or proceeding; (y) the release of such Confidential Records is
         ordered pursuant to a subpoena or other order from a court or
         government body of competent jurisdiction; or (z) the information in
         such Confidential Records has been made generally available to the
         public other than by disclosure in violation of this or any other
         agreement. Abbott agrees that it shall, and shall cause each of its
         Inspectors to, upon learning that disclosure of such Confidential
         Records is sought in or by a court or governmental body of competent
         jurisdiction or through other means, give notice of such request to
         NaPro and allow NaPro, at NaPro's expense, to undertake appropriate
         action to prevent disclosure of the Confidential Records.
         Notwithstanding the foregoing, NaPro may designate any such Records as
         being reviewable only by the Inspectors, and not disclosable to Abbott
         if NaPro reasonably believes that such Records are of a competitively
         sensitive nature, and disclosure to Abbott in accordance with this
         provision would be materially harmful to NaPro's competitive position.
                           (x) NaPro shall hold in confidence and not make any
         disclosure of information concerning Abbott provided to NaPro pursuant
         to this Section 5 unless: (A) disclosure of such information is
         necessary in connection with NaPro's assertion of any claims or actions
         or with its establishment of any defense in any pending administrative
         or judicial action or proceeding; (B) disclosure of such information is
         necessary to comply with federal or state securities laws; (C) the
         disclosure of such information is necessary to avoid or correct a
         misstatement or omission of material fact in the registration statement
         that directly relates to




                                       25
<PAGE>



         Abbott; (D) the release of such information is ordered pursuant to a
         subpoena or other order from a court or governmental body of competent
         jurisdiction; or (E) such information has been made generally available
         to the public other than by disclosure in violation of this Agreement
         or any other agreement. NaPro agrees that it shall, upon learning that
         disclosure of such information concerning Abbott is sought in or by a
         court or governmental body of competent jurisdiction or through other
         means, give notice of such request to Abbott and allow Abbott, at
         Abbott' expense, to undertake appropriate action to prevent disclosure
         of the information deemed confidential.
                           (xi) NaPro shall: (A) cause all the Registrable
         Shares covered by the registration statement to be listed on each
         national securities exchange on which securities of the same class or
         series issued by NaPro are then listed, if any; or (B) secure the
         designation and quotation of all the Registrable Shares covered by the
         registration statement on the Nasdaq National Market.
                           (xii) NaPro shall provide a transfer agent and
         registrar, which may be a single entity, for the Registrable Shares not
         later than the Effective Date.
                           (xiii) NaPro shall enter into such customary
         agreements (including, in the case of an underwritten offering,
         underwriting agreements in customary form as are reasonably
         satisfactory to NaPro with customary representations, warranties and
         covenants and indemnification and contribution obligations) and take
         all such other appropriate actions as Abbott or the underwriters, if
         any, reasonably request in order to expedite or facilitate the
         disposition of such Registrable Shares. Abbott shall be a party to such
         underwriting agreement and may, at its option, require that NaPro make
         to and for the benefit of Abbott the representations, warranties and
         covenants of NaPro and NaPro may, at its option, require that Abbott
         make to and for the benefit of NaPro, the representations, warranties
         and covenants of Abbott, in each case, which are being made to and for
         the benefit of such underwriters.
                           (xiv) NaPro shall use its best efforts to obtain an
         opinion from NaPro's counsel and a "cold comfort" letter from NaPro's
         independent public accountants in customary

         form and covering such matters as are customarily covered by such
         opinions and "cold comfort" letters delivered to underwriters in
         underwritten public offerings, which opinion and letter shall be
         reasonably satisfactory to the underwriter, if any, and to Abbott, and
         furnish to Abbott and to each underwriter, if any, a copy of such
         opinion and letter addressed to Abbott and each underwriter.
                           (xv) NaPro shall cooperate with Abbott and the
         managing underwriter, if any, to facilitate the timely preparation and
         delivery of certificates not bearing any restrictive legends
         representing the Registrable Shares to be sold, and cause such
         Registrable Shares to be issued in such denominations and registered in
         such names in accordance with the underwriting agreement prior to any
         sale of Registrable Shares to the underwriters or, if not an
         underwritten offering, in accordance with the instructions of Abbott at
         least three business days prior to any sale of Registrable Shares and
         instruct any transfer agent and registrar of Registrable Shares to
         release any stop transfer orders in respect thereof.
                           (xvi) NaPro shall take all other reasonable actions
         necessary to expedite and facilitate disposition by Abbott of
         Registrable Shares pursuant to the registration statement.
                           (xvii) If any such registration statement or
         comparable statement under "blue sky" laws refers to Abbott by name or
         otherwise as the holder of any securities of NaPro, then Abbott shall
         have the right to require: (i) the insertion therein of language, in
         form and substance satisfactory to Abbott and NaPro, to the effect that
         the holding by Abbott of such securities is not to be construed as a
         recommendation by Abbott of the investment quality of NaPro's
         securities covered thereby and that such holding does not imply that
         Abbott will assist in meeting any future financial requirements of
         NaPro; or (ii) in the event that such reference to Abbott by name or
         otherwise is not in the judgment of NaPro, as advised by counsel,
         required by the Securities Act or any similar federal statute or any
         state "blue sky" or securities law then in force, the deletion of the
         reference to Abbott.

         6. Certain Limitations. NaPro shall be obligated to effect Demand
Registrations as follows:
                                    (i) no more than two (2) Demand
                  Registrations with respect to the Initial Shares, any of which
                  two (2) Demand Registrations that has not been exercised shall
                  lapse as of the First Additional Closing Date; and
                                    (ii) no more than two (2) Demand
                  Registrations with respect to the aggregate of the Initial
                  Shares and the First Additional Shares after the First
                  Additional Closing Date, any of which two (2) Demand
                  Registrations that has not been exercised shall lapse as of
                  the Second Closing Date; and
                                    (iii) no more than two (2) Demand
                  Registrations with respect to the Shares as of the Second
                  Additional Closing Date. NaPro shall be obligated to effect no
                  more than three (3) Piggyback Registrations with
         respect to all of the Shares. A Registration will not count as one of
         the permitted Registrations under this paragraph 6 until it has become
         effective. If a Registration has remained effective for the
         Registration Period, such Registration shall be deemed to have been
         effected regardless of whether any of the Shares are ultimately sold
         pursuant to the Registration. A Registration that does not become
         effective after NaPro has filed a registration statement with respect
         thereto solely by reason of Abbott's refusal to proceed (other than any
         refusal to proceed based upon: (i) the advice of its counsel that the
         registration statement, or the prospectus contained therein, or other
         documents incorporated by reference therein, contain or contains an
         untrue statement of a material fact or omits to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances then existing;
         or (ii) a material adverse change in the condition (financial or other)
         of NaPro after such registration statement has been filed) shall be
         deemed to have been effected by NaPro. The Demand Registration and
         Piggyback Registration rights of Abbott shall be assignable by Abbott
         only to wholly owned subsidiaries of Abbott to which Abbott has
         transferred all of its Shares.

         7. Holdback. (a) If requested by the managing underwriter or
underwriters in an underwritten offering, or by the initial purchaser or
representative of the initial purchasers in an offering under Rule 144A under
the 1933 Act (a "Rule 144A Offering"), by NaPro of its equity securities (or
rights to acquire such equity securities or securities convertible into or
exchangeable for such equity securities), each holder of Registrable Shares
agrees not to effect any public sale or distribution of any Registrable Shares
of NaPro during the period commencing on the Effective Date of such underwritten
offering or, in the case of a Rule 144A Offering, the date of the definitive
offering memorandum for the Rule 144A Offering (or beginning up to ten (10)
Business Days prior to such date if requested by the managing underwriter or
underwriters in an underwritten offering or by the initial purchaser or
representative of the initial purchasers in a Rule 144A Offering) and continuing
until ninety (90) days following either: (i) the Effective Date of such
underwritten offering or, in the case of a Rule 144A Offering, the date of the
definitive offering memorandum for the Rule 144A Offering; or (ii) such earlier
date, if applicable, except for any Registrable Shares that are part of such
underwritten offering or Rule 144A Offering, as the case may be, or, unless
otherwise permitted by such managing underwriter or underwriters in the case of
an underwritten offering or by the initial purchaser or the representative of
the initial purchasers in a Rule 144A Offering.
                  (b) If requested by the managing underwriter or underwriters
in an underwritten offering of Registrable Shares, NaPro agrees: (i) not to
effect any public sale or distribution or its Common Stock or securities
convertible into or exchangeable or exercisable for Common Stock during the
period commencing on the Effective Date of such underwritten offering (or
beginning up to ten (10) Business Days prior to such date if requested by the
managing underwriter or underwriters) and continuing until ninety (90) days
following either: (A) the Effective Date of such underwritten offering; or (B)
such earlier date, if applicable, except for: (x) securities that are part of
such underwritten offering; (y) securities to be registered on Form S-4 or Form
S-8 or any successor forms; and (z) as otherwise permitted by such managing
underwriter or underwriters; and (ii) to use commercially



                                       29

reasonable efforts to cause each future holder of its privately placed Common
Stock or securities convertible into or exchangeable or exercisable for Common
Stock issued by NaPro after the date of this Agreement to agree not to publicly
sell or distribute such securities during the period referred to in clause (i)
of this Section 7(b).
         8. SEC Filings; Public Information. So long as necessary to permit
Abbott to sell Shares in accordance with Rule 144 under the Securities Act,
NaPro shall use reasonable best efforts to file on a timely basis all reports
required to be filed pursuant to the Securities Exchange Act, and in the event
NaPro is not required to file such reports, NaPro shall make available public
information required pursuant to Rule 144(c) to facilitate any sale by Abbott
pursuant to Rule 144.
         9.       [Reserved].
         10.      Listing of Shares.
                  (a) Not later than the first date that Abbott is permitted to
publicly sell Shares under the terms of this Agreement, NaPro shall (i) prepare
and file with The Nasdaq Stock Market, Inc. (or, if applicable, any national
securities exchange on which the Common Stock is then listed) an application for
listing of the Shares; and (ii) to take all commercially reasonable steps
necessary to cause all such shares to be approved for listing on the Nasdaq
National Market (or, if applicable, any national securities exchange on which
the Common Stock is then listed) as soon as practicable thereafter.
                  (b) Except in the event of a deregistration or delisting that
may result from a transaction affecting NaPro outside of the ordinary course of
its business, NaPro shall use commercially reasonable efforts to keep effective
the registration of the Common Stock under the Securities Exchange Act and
maintain the listing of the Common Stock on the Nasdaq National Market (or, if
applicable, any national securities exchange on which the Common Stock may
become listed).
         11. Press Releases. The Parties agree that, upon execution of this
Agreement, a press release approved by both parties will be issued. Except as
specifically set forth in this Section 11, neither Party (an "Originating
Party") shall: (a) originate any publicity, news release or other public
announcement, written or oral, whether to the public press, stockholders or
otherwise, relating to this Agreement, matters

                                                                  EXECUTION COPY


relevant to this Agreement, amendments hereto or performance by the Parties
hereunder; or (b) use the name of the other Party in any publicity, news release
or other public announcement, except (i) with the prior written consent, review
and approval of the other Party (a "Reviewing Party") in which case the
Originating Party shall forward the proposed public announcement to the
Receiving Party (which, in the case of Abbott, shall be its Manager of Public
Affairs, Hospital Products Division, and in the case of NaPro, shall be its
General Counsel) not less than three (3) Business Days prior to its use or
publication; or (ii) as required by written state or federal securities law or
regulation in the written opinion of legal counsel to the Originating Party, in
which case the Originating Party will give to the Reviewing Party at least one
(1) full twenty-four (24) hour Business Day prior written notice of such
proposed legally required disclosure to review, comment and propose
modifications. In the event that the Reviewing Party fails to respond within the
three (3) Business Day or twenty-four (24) hour period, as the case may be, the
Originating Party shall be free to issue such release without comment from the
Reviewing Party.
         12.      Alternative Dispute Resolution.
                  (a) Contract Breach/Cure. Should either Party breach or be
alleged to have breached this Agreement, the other party may serve notice of
such breach, or alleged breach, in writing upon the breaching party. The Party
receiving such notice shall have ninety (90) days after receipt of the notice to
cure such breach or to demonstrate that no such breach or alleged breach exists.
In the event that any such breach or alleged breach remains unresolved after
such 90-day period, then the matter shall forthwith be referred to alternative
dispute resolution to be conducted in accordance with Exhibit G of the
Development Agreement.
                  (b) Disputes, etc. All disputes, other than a dispute arising
under paragraph (a) above, arising out of, relating to, or connected with this
Agreement, shall forthwith be referred to alternative dispute resolution to be
conducted in accordance with Exhibit G of the Development Agreement.

<PAGE>



                  (c) Exclusive Remedy. The alternative dispute resolution set
forth in Exhibit G of the Development Agreement shall be the exclusive means for
either Party to this Agreement to seek resolution of any dispute arising out of,
relating to, or connected with this Agreement, except that either Party may
bring an action before a competent court for the adoption of provisional or
protective measures or equitable relief. The pendency of matter referred to
alternative dispute resolution to be conducted in accordance with Exhibit G of
the Development Agreement shall not excuse any Party for performance under this
Agreement, it being understood that such performance is without prejudice to the
dispute resolution process.
                  (d) Judicial Review. Judgment on the arbitral award rendered
may be entered in any court having jurisdiction or application may be made to
such for a judicial acceptance of the award and an order of enforcement, as the
case may be.
         13.      Miscellaneous.
                  (a) Survival. The representations and warranties set forth in
this Agreement given in connection with the purchase and sale of the Initial
Shares shall survive the consummation of the purchase and sale of the Initial
Shares and terminate at the end of the twentieth (20th) month after the date of
this Agreement. The representations and warranties set forth in this Agreement
given in connection with the purchase and sale of the First Additional Shares
shall survive the consummation of the purchase and sale of the First Additional
Shares and terminate at the end of the twentieth (20th) month after the First
Additional Closing Date. The representations and warranties set forth in this
Agreement given in connection with the purchase and sale of the Second
Additional Shares shall survive the consummation of the purchase and sale of the
Second Additional Shares and terminate at the end of the twentieth (20th) month
after the Second Additional Closing Date. The covenants and agreements set forth
in this Agreement shall survive the consummation of this Agreement forever
unless terminated earlier in accordance with the terms of this Agreement.
                  (b) Parties and Interest. This Agreement shall bind and inure
to the benefit of the Parties named herein and their respective heirs,
successors and assigns.

                  (c) Entire Transaction. This Agreement, the Development
Agreement and the Loan Agreement constitute the entire agreement between the
Parties with respect to the transactions contemplated by this Agreement and

between the Parties, written or oral, that may have related in any way to the
subject matter of this Agreements.
                  (d) Assignment. Neither Party may assign either this Agreement
or any of its rights, interests or obligations hereunder without the prior
written approval of the other Party, except as otherwise provided herein and
except that Abbott may assign its rights, interests and obligations hereunder to
any of its wholly-owned subsidiaries.
                  (e) Counterparts. This Agreement may be executed in two
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.
                  (f) Headings. The section headings contained in this Agreement
are inserted for convenience only and shall not affect in any way the meaning or

                                With copy to:

                                Attn:  Divisional Vice President
                                Telecopy:  (847) 938-1206

         Either Party may give any notice, request, demand, claim, or other
communication hereunder using any other means (including personal delivery,
expedited courier, messenger service, telecopy, telex, ordinary mail, or
electronic mail), but no such notice, request, demand, claim, or other
communication shall be deemed to have been duly given unless and until it
actually is received by the individual for whom it is intended. Either Party may
change the address to which notices, requests, demands, claims, and other
communications hereunder are to be delivered by giving the other Party notice in
the manner herein set forth.
                  (h) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of Delaware.
                  (i) Amendments and Waivers. No amendment of any provisions of
this Agreement shall be valid unless the same shall be in a writing referring to
this Agreement signed by the Parties. Either Party may waive compliance by the
other Party with any provision of this Agreement, which waiver must be in
writing. No waiver by either Party of any default, misrepresentation, or breach
of warranty or covenant hereunder, whether intentional or not, shall be deemed
to extend to any prior or

<PAGE>

                                                                  EXECUTION COPY


subsequent default, misrepresentation, or breach of warranty or covenant
hereunder or affect in any way any rights arising by virtue of any prior or
subsequent such occurrence.
                  (j) Severability. Any term or provision of this Agreement that
is invalid or unenforceable in any situation in any jurisdiction shall not
affect the validity or enforceability of the remaining terms and provisions
hereof or the validity or enforceability of the offending term or provision in
any other situation or in any other jurisdiction. If the final judgment of a
court of competent jurisdiction declares that any term or provision hereof is
invalid or unenforceable, the Parties agree that the court making the
determination of invalidity or unenforceability shall have the power to reduce
the scope, duration, or area of the term or provision, to delete specific words
or phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Agreement shall be enforceable as so modified after the expiration of the
time within which the judgment may be appealed.
                  (k) Expenses. Except as otherwise provided in this Agreement,
each of the Parties shall bear its own costs and expenses (including legal fees
and expenses) incurred in connection with this Agreement and the transactions
contemplated hereby.
                  (l) Construction. The language used in this Agreement will be
deemed to be the language chosen by the Parties to express their mutual intent,
and no rule of strict construction shall be applied against either Party. Any
reference to any federal, state, local, or foreign statute or law shall be
deemed also to refer to all rules and regulations promulgated thereunder, unless
the context requires otherwise. Any reference to the "transactions contemplated
hereby," the "transactions contemplated by this Agreement," the "transactions
contemplated under this Agreement" or the "transactions contemplated pursuant to
this Agreement" shall be deemed to also refer to any other document, agreement
or certificate to be executed or delivered in connection with the consummation
of the transaction in question contemplated by this Agreement. The Parties
intend that each representation,



                                       35

<PAGE>



warranty, and covenant contained herein shall have independent significance. If
either Party has breached any representation, warranty, or covenant contained
herein in any respect, the fact that there exists another representation,
warranty, or covenant relating to the same subject matter (regardless of the
relative levels of specificity) which the Party has not breached shall not
detract from or mitigate the fact that the Party is in breach of the first
representation, warranty, or covenant.
                  (m) Restrictions on Transfer. Notwithstanding anything to the
contrary set forth in this Agreement and provided the Development Agreement has
not been terminated, Abbott agrees that:
                           (i) Abbott shall not sell or otherwise dispose of the
         Shares issued to it for a period of one (1) year from the date of such
         issuance (as to the Initial Shares, the First Additional Shares and the
         Second Additional Shares, each a "Restricted Period"). From and after
         the end of each Restricted Period, sales or other dispositions of the
         Shares by Abbott shall be limited to an amount not to exceed for each
         365-day period one-half (1/2) of the Shares issued to Abbott for the
         relevant Restricted Period (subject to adjustment for any stock split,
         stock dividend, subdivision or combination of the Common Stock or any
         other change in corporate structure affecting the Common Stock);
         provided, however, that any Shares permitted to be sold, but not sold
         during the first such 365-day period, shall be added to the number of
         Shares permitted to be sold during the second such 365-day period;
                           (ii) Nothing contained in this Section 13(m) shall
         limit the right of Abbott to transfer any of its Shares to a direct or
         indirect wholly owned subsidiary of Abbott.
                           (iii) At the request of NaPro, Abbott shall supply
         written representations to counsel to NaPro upon which such counsel
         shall be entitled to rely in rendering the opinion referred to in
         clause (iii) of the proviso contained in the definition of "Registrable
         Shares." NaPro shall indemnify Abbott, its directors, officers,
         employees and agents, and each Person, if any, who controls Abbott
         within the meaning of the Securities Act or the Securities Exchange
         Act, against all losses, claims, damages, liabilities and expenses
         arising out of or relating to the offer and sale of Registrable Shares
         in reliance on such opinion of counsel described in clause

                                                                  EXECUTION COPY


         (iii) of the proviso contained in the definition of "Registrable
         Shares," except insofar as such losses, claims, damages, liabilities or

         NOW, THEREFORE, in consideration of the premises and the respective
promises herein made, and in consideration of the representations, warranties,
and covenants herein contained, the parties agree as follows:

                              TERMS AND CONDITIONS
SECTION 1.        AMOUNT AND TERMS.
                  1.1 Advances. Abbott hereby agrees, on the terms and subject
to the conditions of this Agreement: (a) to make an advance (the "Initial
Advance") to NaPro in the principal amount of $2,000,000 on the Effective Date;
and (b) to make advances (including the Initial Advance, the "Advances") to
NaPro at any time and from time to time during the period from the Effective
Date to the earlier of: (i) the First Commercial Sale of a Planned Indication or
(ii) the date of notice of termination pursuant to Article 15 of the Development
Agreement; provided that the aggregate principal amount of all such Advances at
any one time outstanding shall not exceed the lesser of: (i) the Commitment
Amount; or (ii) the Borrowing Base at such time (all such Advances together
being called, the "Loan").
                  1.2      Borrowing Request.
                  (a) Each Advance shall be made on notice, evidenced by a
Borrowing Request, given not later than 1:00 p.m. (Chicago time) on the fifth
Business Day prior to the date of the proposed Advance. Each such Borrowing
Request shall be completed in the form of Exhibit B, shall be sent by facsimile
and confirmed thereafter in writing, shall specify the requested: (i) date
Abbott should make the proceeds of such Advance



                                                    2

<PAGE>



available to NaPro pursuant to Section 1.2(b) (the "Drawdown Date"); and (ii)
amount of such Advance (which amount shall not exceed the then Available
Borrowing Base).
                  (b) On the Effective Date and each Drawdown Date thereafter,
Abbott shall make available the amount of the requested Advance by wire transfer
of immediately available funds as set forth in the Borrowing Request to such
address as is set forth in the Borrowing Request.
                  1.3 Promissory Note. The Loan shall be evidenced by a
promissory note of NaPro substantially in the form of Exhibit A to this
Agreement (the "Abbott Note").
                  1.4 Interest. NaPro shall pay interest at the rate of 6.5% per
annum on the unpaid principal amount of the Loan from the Drawdown Date of each
Advance thereunder, in each case until such principal amount shall be paid in
full; provided, however, that any amount of principal which is not paid when due
(whether upon demand (and the expiration of five (5) Business Days), by
acceleration or otherwise) shall bear interest, from the date on which such
amount is due until such amount is paid in full, payable on demand, at a rate of
11% per annum. NaPro shall pay interest on such outstanding principal amount
quarterly on March 31, June 30, September 30 and December 31 of each year (each,
an "Interest Payment Date") until the principal hereof is paid or made available
for payment.
                  1.5 Payments; Optional Prepayments. The entire principal
amount of the Abbott Note and all accrued and unpaid interest thereon shall be
due and payable in full on the earliest of the following dates (such earliest
date being the "Termination Date"):



                                                    3

<PAGE>



                  (a) the second anniversary following the First Commercial
Sale; provided, however, that the principal amount of the Loan shall be off-set
by fifty-percent (50%) of all Milestone Payments and Additional Consideration
due from Abbott to NaPro earned on and following the date of the First
Commercial Sale until such time as two-thirds of such principal amount of the
Loan shall have been paid and such two-thirds of the outstanding principal
amount of the Loan shall be due and payable in installments as all such monies
from Abbott to be applied as such an offset are due and payable;
                  (b) the termination date of the Development Agreement pursuant
to Article 15 thereof (except for termination pursuant to Section 15.5.1 or
15.5.2); or
                  (c) January 1, 2007, provided however, that if Abbott
terminates the Development Agreement pursuant to Section 15.5.1 or 15.5.2 of the
Development Agreement: (i) the due date specified in Section 1.5(a) shall be
extended to the third anniversary following the date of First Commercial Sale;
and (ii) the due date specified in this Section 1.5(c) shall be extended to June
1, 2007.
         NaPro shall have the right, at any time and from time to time, upon not
less than ten (10) Business Days' prior notice to Abbott, in accordance with the
terms of the Abbott Note, to prepay all or any portion of the outstanding
principal amount of the Abbott Note in immediately available funds, without
premium or penalty, provided that NaPro has paid all interest on such Abbott
Note accrued through the date of prepayment. Amounts prepaid, whether pursuant
to a voluntary or mandatory prepayment, may not be reborrowed, except that any
amount prepaid as required under Section 1.6 may be reborrowed if all applicable
conditions precedent are met upon such reborrowing.



                                                    4

<PAGE>



                  1.6 Mandatory Prepayment. If at any time the outstanding
principal amount of the Loan shall exceed the Borrowing Base, NaPro shall within
five (5) Business Days following such event, prepay a principal amount of the
Loan equal to such excess. NaPro agrees that upon receipt of any Faulding
Revenue or the Proceeds of any other Collateral it will, if the Loan would
exceed the Borrowing Base after subtracting such Faulding Revenue or Proceeds
from the Borrowing Base or if the Loan is then due and owing, apply such
Faulding Revenue or other proceeds to the repayment of the Loan; provided,
however, that if NaPro disputes the fact that the outstanding principal amount
of the Loan exceeds the Borrowing Base, and invokes the procedures set forth in
Section 7.2, Abbott's rights shall be stayed subject to determination under
Section 7.2.
                  1.7 Form of Payments. All payments (including prepayments) on
account of principal and interest shall be made in United States dollars and by
wire transfer of immediately available funds. If any payment is scheduled to
become due and payable on a day which is not a Business Day, such payment shall
instead become due and payable on the immediately following Business Day and
such extension of time shall be included in the computation of interest under
this Agreement and the Abbott Note.
                  1.8 Use of Proceeds. The proceeds of Advances shall be used by
NaPro solely to fund general business and working capital needs.



                                                    5

<PAGE>



                  1.9      Notice Requirements.  NaPro hereby covenants and
agrees to furnish to Abbott:
                  (a) as soon as possible and in any event within five (5)
Business Days after the occurrence of each Event of Default known to NaPro which
is continuing on the date of such statement, a statement of an authorized
financial officer of NaPro setting forth the details of such Event of Default
and the actions which NaPro has taken and proposes to take with respect thereto;
                  (b) promptly and in any event within five (5) Business Days
after the sending or filing thereof, copies of all proxy material, reports and
other information which NaPro sends to any of its security holders pursuant to
the Securities Exchange Act of 1934, and copies of all reports and registration
statements which NaPro or any subsidiary files with the Securities and Exchange
Commission, including but not limited to reports on Form 10-Q and Form 10-K;
                  (c) within fifteen (15) Business Days after the last day of
each month, a Borrowing Base Certificate as of such month end.

SECTION 2.        SECURITY INTEREST AND COLLATERAL.
                  2.1 Grant of Security Interest. As consideration for Abbott
making each and all of the Advances, and to secure the prompt and complete
payment, performance and observance of the Obligations, NaPro hereby assigns and
grants to Abbott a continuing first-priority security interest in the following
property, whether now owned or hereafter acquired: (a) the Equipment; (b) the
Inventory; (c) the Accounts; (d) the Faulding Revenue; (e) the Yew Trees; and
(f) all Proceeds thereof (all of (a), (b), (c),



                                                    6

<PAGE>



(d), (e) and (f) collectively, the "Collateral"). NaPro hereby covenants and
agrees that Abbott may exercise in respect of the Collateral, solely upon
becoming entitled to such exercise pursuant to this Agreement and in addition to
other rights and remedies provided for in this Agreement or otherwise available
to it, all the rights and remedies of a secured party on default under the
Uniform Commercial Code as in effect in the State of Illinois (the "U.C.C."),
whether or not the U.C.C. applies to the Collateral.
                  2.2 Rights of Abbott. Except as otherwise expressly provided
herein, Abbott shall not be permitted to exercise any of its rights to the
Collateral under this Agreement unless and until there shall have occurred and
be continuing an Event of Default and then only to the extent of the
Obligations. Upon the occurrence of an Event of Default, Abbott may deliver to
NaPro a written notice stating: (i) that an Event of Default has occurred and is
continuing; and (ii) that Abbott elects to exercise its rights to the
Collateral, which notice shall specify whether Abbott elects to exercise its
rights with respect to the Faulding Revenue (the "Collateral Exercise Notice").
If NaPro disputes the existence of an Event of Default, it shall within two (2)
Business Days of receipt of the Collateral Exercise Notice, so advise Abbott and
may invoke the procedures set forth in Section 7.2 to determine if an Event of
Default has occurred.
                  2.3      Obligations of NaPro.
                  (a) Faulding Revenue. NaPro hereby covenants and agrees to
notify Faulding in writing within thirty (30) days after the date hereof to pay
a lockbox account (the "Lock Box Account") with a bank (the "Lock Box Bank")
satisfactory to Abbott and NaPro pursuant to documentation satisfactory to
Abbott and NaPro amounts equal to the Faulding Revenue. Until the delivery of a
Collateral Exercise Notice to NaPro and the



                                                    7

<PAGE>



Lock Box Bank, the Lock Box Bank shall release funds in the Lock Box Account to
NaPro on a daily basis. After the delivery of a Collateral Exercise Notice, the
Lock Box Bank will release funds directly to Abbott to be applied to the
Obligations; provided, however, that if NaPro disputes the existence of any
Event of Default and invokes the procedures under Section 7.2, the Lock Box Bank
shall hold all monies in the Lock Box Account pending resolution of such
procedures. Any of the Faulding Revenue received by NaPro after delivery of a
Collateral Exercise Notice shall be held in trust by NaPro and NaPro shall
deliver to the Lock Box Bank in original form all money, checks, money orders,
notes or other means of or evidences of payment in respect of the Faulding
Revenue. When and if an Event of Default has been cured or is otherwise no
longer continuing, Abbott covenants and agrees that it will immediately execute
a joint notice with NaPro directing the Lock Box Bank to resume releasing funds
in the Lock Box Account to NaPro on a daily basis. The joint notice sent by the
Parties shall indicate the date as of which the release of funds to NaPro shall
resume and Abbott shall be entitled to receive the funds in the Lock Box Account
only up to such date.
                  (b) Other Collateral. NaPro hereby covenants and agrees that
upon receipt of a Collateral Exercise Notice that includes an election by Abbott
to exercise rights with respect to Equipment, Inventory or Yew Trees
constituting Collateral: (i) NaPro shall, at NaPro's expense and upon the
reasonable request of Abbott, within ten (10) Business Days of NaPro's receipt
of the Collateral Exercise Notice, (A) assemble all or part of the Equipment and
Inventory constituting the Collateral as reasonably directed by Abbott, and
NaPro shall make such Equipment and Inventory available to Abbott at a place and
time that is reasonably convenient to both Parties and (B) NaPro shall promptly



                                                    8

<PAGE>



notify each of the landlords on whose property the Yew Trees are growing of
Abbott's intent to exercise its rights to realize upon such Collateral; (ii)
NaPro shall permit Abbott upon reasonable advance notice of not less than ten
(10) Business Days to enter upon any premises of NaPro and take possession of
such Collateral; and (iii) NaPro shall permit Abbott, without notice except as
specified below, to sell such Collateral or any part thereof in one or more
parcels at public or private sale, at any of NaPro's offices or elsewhere, at
such time or times, for cash, on credit or for future delivery, and at such
price or prices and upon such other terms as Abbott may deem commercially
reasonable. NaPro agrees that, to the extent notice of sale shall be required by
law, at least ten (10) Business Days notice to NaPro of the time and place of
any public sale or the time after which any private sale is to be made shall
constitute reasonable notification. At any sale of such Collateral, if permitted
by law, Abbott may bid (which bid may be, in whole or in part, in the form of
cancellation of indebtedness) for the purchase of such Collateral or any portion
thereof for the account of Abbott. Abbott shall not be obligated to make any
sale of Collateral regardless of whether a notice of sale has been given.
Subject to Sections 7.2 and 7.3, NaPro shall not be liable for any deficiency.
Abbott may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefor, and such sale may, without further notice,
be made at the time and place to which it was so adjourned. Subject to Sections
7.2 and 7.3, Abbott shall be required to proceed against the Collateral and may
not proceed against NaPro directly.
         If NaPro disputes the existence of an Event of Default and invokes the
procedures set forth in Section 7.2, Abbott's rights shall be stayed subject to
determination under Section 7.2.

                  2.4 NaPro Covenants Regarding Faulding Agreement. NaPro
covenants that during the term of this Agreement, it shall use commercially
reasonable efforts to keep in full force and effect the Faulding Agreement in
accordance with the terms hereof as of the Effective Date. NaPro shall use
commercially reasonable efforts to enforce its rights under the Faulding
Agreement. In the event that a default exists under the Faulding Agreement by
either NaPro or Faulding, NaPro shall provide to Abbott prompt written notice of
such default, including the nature of the default and the actions to be taken by
the defaulting party to remedy the default. NaPro shall not amend any terms of
the Faulding Agreement or waive any of its rights thereunder without the prior
written consent of Abbott, which consent shall not be unreasonably withheld or
delayed.
                  2.5      Perfection and Protection of Security Interest.
                   (a) NaPro shall perform all steps requested by Abbott at any
time to perfect, maintain, protect and enforce Abbott's security interest,
including, without limitation: (i) executing and filing financing or
continuation statements, and amendments thereof, in form and substance
satisfactory to Abbott; (ii) delivering to Abbott the originals of all
instruments, documents and chattel paper, and all other Collateral of which
Abbott determines it should have physical possession in order to perfect and
protect Abbott's security interest therein, duly pledged, endorsed or assigned
to Abbott without restriction; (iii) delivering to Abbott warehouse receipts
covering any portion of the Collateral located in warehouses and for which
warehouse receipts are issued; (iv) when an Event of Default exists,
transferring Inventory to warehouses designated by Abbott; (v) placing notations
on NaPro's books of account to disclose Abbott's security interest; and (vi)
taking such other steps as are deemed necessary or desirable by Abbott



                                                    10

<PAGE>



to maintain and protect Abbott's security interest. To the extent permitted by
applicable law, Abbott may file, without NaPro's signature, one or more
financing statements disclosing Abbott's security interest. NaPro agrees that a
carbon, photographic, photostatic, electronic or other reproduction of a
financing statement is sufficient as a financing statement. All reasonable
out-of-pocket expenses of NaPro under this Section 2.5(a) prior to the existence
of an Event of Default shall be reimbursed by Abbott. All reasonable out-of
- -pocket expenses of Abbott under this Section 2.5 (a) after an Event of Default
has occurred and is continuing shall be reimbursed by NaPro.
                  (b) If any Collateral is at any time in the possession or
control of any warehouseman, bailee or any of NaPro's agents or processors, then
NaPro shall notify Abbott thereof. At Abbott's request, NaPro shall notify such
Person of Abbott's security interest in such Collateral and, upon Abbott's
request, NaPro shall instruct such Person to hold all such Collateral for
Abbott's account subject to Abbott's instructions and NaPro shall obtain such
documents relating thereto as Abbott shall request; provided, however, that if
the action of NaPro requested under this sentence is not required to perfect
Abbott's security interest, NaPro shall not be required to take such action
unless a Collateral Exercise Notice has been delivered. If at any time any
Collateral is located on any operating facility of NaPro which is not owned by
NaPro, then NaPro shall use commercially reasonable efforts to obtain within 30
days following (i) the Effective Date for those facilities in effect on the
Effective Date and (ii) the leasing of facilities after the date hereof, written
waivers of all present and future liens to which the owner or lessor of such
premises may be entitled to assert against the Collateral and consents with
respect to the liens of Abbott, all in form satisfactory to Abbott.

                  2.6 Location of Collateral. NaPro represents and warrants to
Abbott that: (a) Schedule 1 is a correct and complete list of NaPro's chief
executive office, the location of its books and records, the locations of the
Collateral and the locations of all of its other places of business; and (b)
Schedule 1 correctly identifies any of such facilities and locations that are
not owned by NaPro and sets forth the names of the owners and lessors or
sublessors of and, the holders of any mortgages on, such facilities and
locations. NaPro covenants and agrees that it will not: (i) maintain any
Collateral at any location other than those locations listed for NaPro on
Schedule 1; (ii) otherwise change or add to any of such locations; or (iii)
change the location of its chief executive office from the location identified
in Schedule 1, unless it gives Abbott at least thirty (30) days' prior written
notice thereof and executes any and all financing statements and other documents
that Abbott requests in connection therewith or, if such new location would not
require any additional financing statements to be filed to maintain Abbott's
perfected security interest in all Collateral, five (5) days' prior written
notice thereof. Without limiting the foregoing, NaPro represents that all of its
Inventory (other than Inventory in transit) is, and covenants that all of its
Inventory will be, located, either: (a) on premises owned by NaPro; (b) on
premises leased by NaPro, provided that NaPro has used commercially reasonable
efforts to obtain an executed landlord waiver from the landlord of such premises
in form and substance satisfactory to Abbott; or (c) with any warehouseman,
bailee or any of NaPro's agents or processors, provided that Abbott has received
such documents relating thereto in form and substance satisfactory to Abbott as
Abbott shall request.



                                                    12

<PAGE>



                  2.7 Title to, Liens on, and Sale and Use of Collateral. NaPro
represents and warrants to and agrees with Abbott that: (a) NaPro owns and will
continue to own (or in the case of the Yew Trees in Canada will own or have
rights in such Yew Trees) all of the Collateral free and clear of all Liens
whatsoever, except for Permitted Liens and Specified Liens as set forth on
Schedule 1; (b) Abbott's security interest in the Collateral will not be subject
to any prior lien, except for Specified Liens; (c) NaPro will use, store and
maintain the Collateral with all reasonable care and will use such Collateral
for lawful purposes only; and (d) NaPro will not, without Abbott's prior written
approval, sell, or dispose of or permit the sale or disposition of any of the
Collateral except for sales of Inventory in the ordinary course of business,
sales of Equipment as permitted by Section 2.12 and harvesting trees in the
ordinary course of business and except that NaPro may use the Faulding Revenue
and the Proceeds in the ordinary course of business.
                  2.8 Appraisals. Whenever an Event of Default exists, and at
such other times not more frequently than once a year as Abbott requests, NaPro
shall, upon Abbott's request, provide Abbott with appraisals or updates thereof
of any or all of the Collateral (it being understood that: (a) the Inventory and
Equipment may be appraised separately at different times and that any such
appraisal of Inventory and Equipment shall together constitute one appraisal for
purposes of the limitation described above; and (b) the appraiser and the
preparation basis to be mutually satisfactory to Abbott and NaPro), such
appraisals and updates to include, without limitation, information required by
applicable law and regulation. NaPro and Abbott agree that an appraisal by the
same appraiser who prepared the Original Collateral Appraisal prepared in the
same manner as the Original Collateral Appraisal would be mutually satisfactory.
Abbott shall bear the



                                                    13

<PAGE>



cost of any appraisal before an Event of Default. NaPro shall bear the cost of
any appraisal after an Event of Default has occurred and is continuing.
                  2.9 Access and Examination; Confidentiality. Abbott may, at
all reasonable times during regular business hours with reasonable notice to
NaPro (and at any time when an Event of Default exists) have access to, examine,
audit, make extracts from or copies of and inspect any or all of NaPro's
records, files, and books of account and the Collateral, and discuss NaPro's
affairs with NaPro's officers and management. Abbott may, at any time when an
Event of Default exists, make copies of all of NaPro's books and records related
to the Collateral, or require NaPro to deliver such copies to Abbott. Any
out-of-pocket expenses of Abbott under this section prior to an Event of Default
shall be at Abbott's own expense and after an Event of Default has occurred and
is continuing shall be at NaPro's expense.
                  2.10 Accounts. (a) NaPro hereby represents and warrants to
Abbott, that: (i) each existing Account represents, and each future Account will
represent, a bona fide sale or lease and delivery of goods by NaPro, or
rendition of services by NaPro, in the ordinary course of NaPro's business; and
(ii) each existing Account is, and each future Account will be, for a liquidated
amount payable by the account debtor thereon on the terms set forth in the
invoice therefor, without any offset, deduction, defense, or counterclaim except
those known to NaPro and disclosed to Abbott pursuant to this Agreement.
                  (b) NaPro shall not accept any note or other instrument
(except a check or other instrument for the immediate payment of money) with
respect to any Account unless NaPro will deliver such instrument to Abbott,
endorsed by NaPro to Abbott in a



                                                    14

<PAGE>



manner satisfactory in form and substance to Abbott (which endorsement may be on
an allonge attached to the note) within ten (10) days of the execution and
delivery thereof.
                  2.11 Collection of Accounts; Payments. (a) Until Abbott
notifies NaPro to the contrary after the occurrence and during the continuance
of an Event of Default, NaPro shall make collection of all Accounts and other
Collateral. After such notice, NaPro shall receive all payments as Abbott's
trustee, and shall immediately deliver all payments in their original form duly
endorsed in blank into the Lock Box Account subject to documentation acceptable
to Abbott. NaPro shall, after such notice, instruct all account debtors to make
all payments directly to the address(es) established for such service. All items
sent to any such address shall be deposited in the Lock Box Account. If,
notwithstanding such instructions, after such notice, NaPro receives any
proceeds of Accounts, it shall receive such payment as Abbott's trustee, and
shall immediately deliver such payments to Abbott in their original form duly
endorsed in blank or deposit them into the Lock Box Account, as Abbott may
direct. All collections received in any such lock-box or the Lock Box Account or
directly by Abbott and all funds in the Lock Box Account or other account to
which such collections are deposited shall, after such notice, be credited to
repayment of the Loan. Abbott or Abbott's designee may, at any time after the
occurrence of an Event of Default, notify account debtors that the Accounts have
been assigned to Abbott and of Abbott's security interest therein, and may
collect them directly and charge the reasonable collection costs and expenses to
NaPro as a Loan, not subject to the limitations of Section 2.3(b). So long as an
Event of Default has occurred and is continuing, NaPro, at Abbot's request,
shall execute and deliver to Abbott such



                                                    15

<PAGE>



documents as NaPro shall require to grant Abbott access to any post office box
in which collections of Accounts are received.
                  (b) If sales of Inventory are made for cash after the
occurrence and during the continuance of an Event of Default, NaPro shall
immediately deliver to Abbott or deposit into the Lock Box Account the cash
which NaPro receives.
                  (c) All payments, including immediately available funds
received by Abbott at a bank designated by it, received by Abbott on account of
Accounts or as proceeds of other Collateral will be Abbott's sole property for
its benefit and will be credited to the Loans (conditional upon final
collection).
                  2.12     Equipment.
                  (a) NaPro represents and warrants to Abbott and agrees with
Abbott that all of the Equipment is and will be used or held for use in NaPro's
business, and is and will be fit for such purposes. NaPro shall keep and
maintain the Equipment in good operating condition and repair (ordinary wear and
tear excepted) and shall make all necessary replacements thereof.
                  (b) NaPro shall promptly inform Abbott of any material
additions to or deletions from the Equipment exceeding $50,000 with respect to
any single transaction. NaPro shall not, without Abbott's prior written consent,
permit any Equipment to become a fixture with respect to real property or to
become an accession with respect to other personal property with respect to
which real or personal property Abbott does not have a security interest.
                  (c) NaPro shall not, without Abbott's prior written consent,
sell, lease as a lessor, or otherwise dispose of any of its Equipment; provided,
however, that NaPro



                                                    16

<PAGE>



is permitted to sell, lease as a lessor, or otherwise dispose of any of its
Equipment in the ordinary course of business, provided, however, that if an
Event of Default has occurred and is continuing or if at the time of the
disposition, the then outstanding principal amount of the Loan exceeds the
Borrowing Base, NaPro shall not, without Abbott's prior written consent, sell,
lease as a lessor, or otherwise dispose of any of its Equipment, except that
NaPro may dispose of obsolete or unusable Equipment having an orderly
liquidation value no greater than $50,000 in the aggregate in any Fiscal Year,
without Abbott's consent.
                  2.13 Right to Cure. Abbott may, in its discretion, pay any
amount or do any act required of NaPro hereunder in order to preserve or protect
the Collateral or Abbott's security interest therein, and which NaPro fails to
pay or do, including, without limitation, payment of any judgment against NaPro,
any insurance premium, any warehouse charge, any finishing or processing charge,
any landlord's claim, and any other lien upon or with respect to the Collateral;
provided, that, Abbott shall give NaPro reasonable notice prior to any such
action or payment under this Agreement or under any agreement between Abbott and
an owner or lessor of real property leased by NaPro as lessee. All payments that
Abbott makes under this Section 2.13 and all out-of-pocket costs and expenses
that Abbott pays or incurs in connection with any action taken by it hereunder,
after the occurrence and during the continuation of an Event of Default and at
such other times as Abbott is authorized hereunder to pay or incur such costs or
expenses, shall be reimbursed by NaPro and such reimbursement shall not be
subject to the limitations set forth in Section 2.3(b).



                                                    17

                  2.14 Power of Attorney. NaPro hereby appoints Abbott and
Abbott's designee as NaPro's attorney, with power: (a) to endorse NaPro's name
on any checks, notes, acceptances, money orders or other forms of payment or
security that come into Abbott's possession; (b) to sign NaPro's name on any
invoice, bill of lading, warehouse receipt or other document of title relating
to any Collateral, on financing statements and other public records and file
such financing statements by electronic means with or without a signature as
authorized or required by applicable law or filing procedures; and (c) to do all
things reasonably necessary to protect its interest in or exercise its rights
with respect to the Collateral. NaPro ratifies and approves all acts of such
attorney. Abbott shall exercise at least the same standard of care in exercising
its rights under this Section as it does in administering its own affairs. This
power, being coupled with an interest, is irrevocable until this Agreement has
been terminated. Abbott shall not exercise its rights under this Section unless
an Event of Default exists and Abbott has given NaPro at least two Business
Days' notice of such Event of Default. If NaPro disputes the existence of such
Event of Default, it may invoke the procedures under Section 7.2 and Abbott's
rights shall be stayed subject to determination under Section 7.2.
                  2.15     Insurance.
                  (a) NaPro shall maintain with financially sound and reputable
insurers rated at least A+ by A.M. Best Company, insurance against loss or
damage by fire with extended coverage; theft, burglary, pilferage and loss in
transit; public liability and third party property damage; larceny, embezzlement
or other criminal liability; business interruption; public liability and third
party property damage; and such other hazards or of such other types as is
customary for Persons engaged in the same or similar business, and



                                                    18

<PAGE>



under policies acceptable to Abbott. Without limiting the foregoing, NaPro shall
also maintain flood insurance, in the event of a designation of the area in
which any of the Equipment or Inventory is located as "flood prone" or a "flood
risk area," as defined by the Flood Disaster Protection Act of 1973, in an
amount to be reasonably determined by Abbott, and shall comply with the
additional requirements of the National Flood Insurance Program as set forth in
said Act.
                  (b) NaPro shall cause Abbott to be named in each such policy
as secured party or mortgagee and sole loss payee or additional insured, in a
manner acceptable to Abbott. Each policy of insurance shall contain a clause or
endorsement requiring the insurer to give not less than thirty (30) days' prior
written notice to Abbott in the event of cancellation of the policy for any
reason whatsoever and a clause or endorsement stating that the interest of
Abbott shall not be impaired or invalidated by any act or neglect of NaPro or
the owner of any premises or the occupation of any premises for purposes more
hazardous than are permitted by such policy. All premiums for such insurance
shall be paid by NaPro when due, and certificates of insurance and, if requested
by Abbott, photocopies of the policies, shall be delivered to Abbott. If NaPro
fails to procure such insurance or to pay the premiums therefor when due, Abbott
may do so and the obligation to reimburse Abbott for such insurance premiums
shall not be subject to the limitations set forth in Section 2.3(b). SECTION 3.
CONDITIONS PRECEDENT.
                  3.1 Conditions to Initial Advance. The obligation of Abbott to

being true and correct; (ii) no Event of Default has occurred and is continuing
after giving effect to such Advance; and (iii) Abbott's receipt of a completed
Borrowing Request in the form of Exhibit B. The delivery of a Borrowing Request
by NaPro shall be deemed a representation as of the date of such delivery as to
the matters set forth in clauses (i) and (ii).

SECTION 4.        REPRESENTATIONS AND WARRANTIES.
                  4.1 Representations and Warranties of NaPro. In order to
induce Abbott to enter into this Agreement and to make the Advance, NaPro
represents and warrants that:
                  (a) Authority of NaPro. NaPro is a corporation duly organized,
validly existing, and in good standing under the laws of the State of Delaware.
NaPro has all requisite power and authority to own and operate its properties
and to carry on its business as now conducted and as presently proposed to be
conducted, and is duly licensed or qualified and is in good standing as a
foreign corporation in each jurisdiction wherein the nature of the business
transacted by it or the nature of the property owned or leased by it makes such
licensing or qualification necessary or advisable, except where the failure to
be so licensed or qualified would not have a material adverse effect on NaPro
and its subsidiaries taken as a whole. NaPro has the corporate power and
authority to execute and deliver this Agreement, and to perform its obligations
under this Agreement. All corporate action required to be taken by NaPro to
authorize the execution, delivery and performance of this Agreement has been
duly taken.



                                                    21

<PAGE>



                  (b) Authorization; Enforceable Obligations This Agreement and
the Abbott Note have been duly authorized, executed and delivered by NaPro and
constitute the legal, valid and binding obligations of NaPro, enforceable
against NaPro in accordance with their respective terms (except to the extent
that enforcement may be limited by any applicable bankruptcy, reorganization,
moratorium or similar laws then in effect which may affect the enforceability of
creditors' rights generally, or by general equitable principles).
                  (c) No Legal Bar. The execution, delivery and performance of
this Agreement and the Abbott Note by NaPro: (i) are not and will not be in
violation of the charter or bylaws of NaPro; (ii) are not and will not be in
violation of or conflict with any law or governmental rule or regulation,
judgment, writ, order, injunction, award or decree of any court, arbitrator,
administrative agency or other governmental authority applicable to NaPro; (iii)
are not and will not conflict or be inconsistent with, or result in any breach
of, any of the terms, covenants, conditions or provisions of or constitute a
Event of Default under any indenture, mortgage, material contract, deed of
trust, debenture, material agreement or other material undertaking or material
instrument to which NaPro is a party or by which any of the Collateral may be
bound or affected; and (iv) do not and will not result in the creation or
imposition of any lien on any of the Collateral pursuant to the provisions of
any such indenture, mortgage, contract, deed of trust, debenture, agreement or
other undertaking or instrument.
                  (d) No Debt Restrictions. No note, bond, debenture, indenture,
mortgage, material contract, deed of trust, material agreement or other material
undertaking or material instrument to which NaPro is subject contains any
restriction on



                                                    22

<PAGE>



NaPro's incurring of indebtedness under this Agreement or the Abbott Note,
except such restrictions as have been waived in writing (copies of which shall
be furnished to Abbott).
                  (e) No Consents. No permit, consent, approval or authorization
of, or declaration to or filing with, any governmental authority is required in
connection with the execution, delivery and performance of this Agreement or the
Abbott Note by NaPro or in connection with any transaction contemplated by this
Agreement, which would materially interfere with performance hereunder if not
obtained.
                  (f) Regarding the Collateral. Except as set forth in Schedule
1, NaPro has good, free and clear title to the Collateral and has not previously
assigned or transferred the Collateral or any interest therein. The Collateral
is not subject to any security interest whatsoever, nor is it subject to the
lien of any other Person except as set forth in Schedule 1.
                  (g) Appraisal. All written information provided to Abbott by
NaPro in connection with the preparation of the Original Collateral Appraisal is
true and correct in all material respects. All oral responses by NaPro to
questions in the preparation of the Original Collateral Appraisal were true and
correct in all material respects, to the extent that such responses were made by
employees having responsibility with respect to the subject matter of the
questions. The Original Collateral Appraisal represents a true and accurate
description in all material respects of the assets of NaPro listed therein as of
the date of the Original Collateral Appraisal. NaPro has reviewed the Original
Collateral Appraisal and represents that it does not include any manifest error.
NaPro represents and warrants there has been no material adverse change in the
condition, existence or ownership of the Collateral from the date of the
Original Collateral Appraisal.

                  (h) The Faulding Agreement. The Faulding Agreement is in full
force and effect and neither Faulding nor NaPro is in default thereunder. A
true, accurate and complete copy of the Faulding Agreement, as of the date of

                  6.2 Consequences of Demand and Events of Default.
Notwithstanding any other provision in this Agreement, the Abbott Note or any
other document executed in connection with this Agreement, upon the occurrence
and continuation of an Event of Default, Abbott has the right at any time to
demand payment (which payment shall be due five (5) Business Days after such
demand) by NaPro of all principal, interest and other amounts due under the
Abbott Note or this Agreement and, if NaPro shall fail to pay such amount,
Abbott shall have the right to enforce payment of the Abbott Note or any part
thereof and to exercise any and all rights and remedies in connection with the
Collateral provided by the U.C.C., as well as other rights and remedies in
connection with the Collateral possessed by Abbott under this Agreement or
otherwise at law or equity. Upon the occurrence of any one or more of the Events
of Default and at any time thereafter that such Event of Default shall be
continuing, Abbott may, by notice to NaPro, declare any amounts payable on
account of and the entire unpaid principal amount of the Abbott Note and all
interest accrued and unpaid thereon to be immediately due and payable, whereupon
the Abbott Note and all such accrued and unpaid interest thereon shall become
immediately due and payable without presentment, demand, or protest or further
notice of any kind, all of which are hereby waived by NaPro. Upon the occurrence
and the continuation of any one or more Events of Default and the expiration of
five (5) Business Days after demand by Abbott for payment of the Abbott Note and
amounts owed under this Agreement, interest shall accrue at the applicable Event
of Default rate as provided in Section 1.4. Upon the occurrence of an Event of

Payments or Additional Consideration under the Development Agreement against
payments due by NaPro to Abbott pursuant to this Agreement (including principal,
interests and any applicable penalties). Any withholding or offset of payments
for Milestone Payments or Additional Consideration by Abbott pursuant to this
Section 6.2 shall not constitute a breach or any other default by Abbott under
this Agreement, the Stock Purchase Agreement or the Development Agreement or
waiver of NaPro's obligations under those agreements. Notwithholding the
foregoing, if NaPro disputes the existence of such Event of Default and invokes
the procedures set forth in Section 7.2, Abbott's rights shall be stayed subject
to determination under Section 7.2.

any breach, alleged breach, asserted Event of Default, or any Claim as defined
in Section 7.4) shall forthwith be referred to alternative dispute resolutions
("ADR") to be conducted in accordance with the provisions of Section 7.2(a)
hereof. All disputes arising out of, relating to, or connected with this

to be conducted in accordance with Article 16 and Exhibit G of the Development
Agreement. Either of these ADR procedures shall be the exclusive means for
either Party to this Agreement to seek resolution of any dispute arising out of,
relating to, or connected with this Agreement. The pendency of any matter
referred to ADR to be conducted in accordance with Section 7.2(a) hereof or in
accordance with Article 16 and Exhibit G of the Development Agreement, as the
case may be, shall not excuse any Party from performance under this Agreement,
it being understood that such performance is without prejudice to the dispute
resolution process.
                  (a) The Parties agree that within thirty days following the
first Advance, they will agree upon a mutually acceptable list of five neutrals
to preside in the resolutions of any disputes under this Section 7.2(a) (each, a
"Neutral"). (All references to days in this Section 7.2(a) are to calendar
days.) In the event of a dispute to which this Section 7.2(a) applies, either
Party may send prior written notice to the other Party of such dispute,
specifying the nature of the dispute. The Parties shall use reasonable efforts
to resolve the dispute. If the Parties have not resolved the dispute within
three days, a



                                                    40

<PAGE>



Party seeking resolution under this Section 7.2(a) may send written notice (an
"ADR Notice") to the other Party of the issues to be resolved by ADR and of a
date for an ADR hearing, which date shall be no earlier than ten (10) days
following the receipt of such notice by the other Party. The Party who sends an
ADR Notice shall contact the Neutrals to schedule one of them, whomever may be
available, to preside at the scheduled ADR hearing. From the date that NaPro
receives such an ADR Notice from Abbott until the ruling following the ADR
hearing is rendered, NaPro shall not sell or otherwise dispose of any
Collateral, other than sales of Inventory in the ordinary course of business.
Within three (3) days following receipt of an ADR Notice, the receiving Party
may send written notice to the sending Party of additional issues to be resolved
within the ADR resolution process. No later than three (3) days prior to the
hearing date, the Parties shall exchange and submit to the Neutral: (i) a copy
of all exhibits on which such Party intends to rely in any oral or written
presentation to the Neutral; (ii) a list of any witnesses such Party intends to
call at the ADR hearing, and a short summary of the anticipated testimony of
each witness; (iii) a proposed ruling on each issue to be resolved, together
with a request for a specific damage award or other remedy for each issue (which
proposed rulings and remedies shall not contain any recitation of the facts or
any legal arguments and shall not exceed one (1) page per issue); (iv) a brief
in support of such Party's proposed rulings and remedies, provided that the
brief shall not exceed twenty (20) pages (which page limit shall apply
regardless of the number of issues raised in the ADR proceedings). Except as
expressly set forth in the prior sentence, no discovery shall be required or
permitted by any means, including depositions, interrogatories, requests for
admissions, or production of documents. The ADR hearing shall be conducted on
one (1) day. Each Party shall



                                                    41

<PAGE>



have three (3) hours of hearing time to present its case. Otherwise, the hearing
shall be governed by the rules set forth in paragraph 5(b) through 5(e) of
Exhibit H to the Development Agreement. Within three (3) days following
completion of the hearing, each Party may submit to the other Party and the
Neutral a post-hearing brief in support of its proposed rulings and remedies,
provided that such brief shall not contain or discuss any new evidence and shall
not exceed ten (10) pages, regardless of the number of issues raised in the ADR
proceeding. The Neutral shall rule on each disputed issue within six (6) days
following completion of the hearing. Such ruling shall adopt in its entirety the
proposed ruling and remedy of one of the Parties on each disputed issue, but may
adopt one Party's proposed rulings and remedies on some issues and the other
Party's proposed rulings and remedies on other issues. The Neutral shall not
issue any written opinion or otherwise explain the basis of the ruling. The
provisions of paragraphs 8, 9 and 10 of Exhibit G to the Development Agreement
shall apply to resolution under this Section 7.2(a).
                  7.3 Costs and Expenses. NaPro shall pay or reimburse Abbott
within five Business Days after demand for all costs and expenses incurred by
Abbott (including any attorneys' cost or expenses, which attorneys may be
employees of Abbott) in connection with the enforcement, attempted enforcement,
or preservation of any rights or remedies under this Agreement during the
existence of an Event of Default or after acceleration of the Loans (including
in connection with any "workout" or restructuring regarding the Loans, and
including in any insolvency proceeding or appellate proceeding).
                  7.4      Indemnification.  To the extent not prohibited by
applicable law, NaPro shall indemnify, defend and hold Abbott and each of its
officers, directors,



                                                    42

employees, counsel, agents and attorneys-in-fact (each, an "Indemnified Person")
harmless from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, charges, expenses and disbursements
(including any attorneys' costs or expenses, which attorneys may be employees of
Abbott) (a "Claim") of any kind or nature whatsoever which may at any time
(including at any time following repayment of the Loans) be imposed on, incurred
by or asserted against any such Indemnified Person arising by: (i) the breach by
NaPro of any of its covenants or agreements under this Agreement (other than the
agreement to pay principal and interest on the Loans; or (ii) arising from any
representation made by NaPro hereunder or in any statement or document delivered
or connection herewith being untrue or incorrect in any material respect,
including with respect to any investigation, litigation or proceeding (including
any insolvency proceeding or appellate proceeding) (any of the foregoing being a
"Breach") related to or arising out of this Agreement or the Loans or the use of
the proceeds thereof, whether or not any Indemnified Person is a party thereto.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 7.3 shall not apply to: (i) any Claim to the
extent that the relief sought with respect to such Claim is for payment by NaPro
of amounts due under the Loan; (ii) a Claim arising out of or based upon a
Breach which occurs in reliance upon and in conformity with information
furnished in writing to NaPro by such Indemnified Person; (iii) amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of NaPro, which consent however, shall not be unreasonably withheld; or
(iv) claims aggregating after the date hereof an amount not exceeding $1,500.
The agreements in this Section shall survive payment of the Loans and



                                                    43

provision of this Agreement or the Abbott Note.
                  7.5 Amendment and Waiver. This Agreement may not be amended or
modified except by written agreement of NaPro and Abbott and no consent or
waiver hereunder shall be valid unless in a writing that refers to this
Agreement, signed by NaPro and Abbott.
                  7.6 Delay not a Waiver; Cumulative Remedies. No failure or
delay on the part of either Abbott or NaPro in exercising any right, power or
privilege under this Agreement or the Abbott Note shall operate as a waiver, nor
shall any single or partial exercise of any right, power or privilege preclude
any other or further exercise or the exercise of any other right, power or
privilege. The rights and remedies provided in this Agreement and the Abbott
Note are cumulative and not exclusive of any rights or remedies provided by law.
                  7.7 Notices. All notices, demands or other communications to
