     (b)  Consideration  for License.  In  consideration  of the License and the
other rights granted to BNP pursuant to the terms of this Agreement:

     (i) Within two (2) business days after the Effective Date, BNP shall make a
payment to NaPro equal to six million seventy thousand  dollars  ($6,070,000) by
wire transfer of immediately  available funds to an account designated by NaPro;
provided, however, that two million dollars ($2,000,000) of such amount shall be
placed in escrow (the "Escrow  Payment") and  transferred to NaPro in accordance
with the provisions of Section 6(b)(iv) hereof;

     (ii) Within five (5) business days after NaPro files its 1997 annual report
on Form 10-K and  delivers a copy of such report to BNP,  BNP shall  transfer to
NaPro one million one hundred  twenty six thousand  three  hundred  ninety eight
(1,126,398) shares of NaPro common stock ("Common  Stock"),which  transfer shall

effect  and (2) the BNP  Formulation  would  infringe  the  claims of the issued
patent,  provided,  however,  that if BNP believes that the BNP Formulation does

such patent.

                  (c) No Assignment or Transfer.  The License is personal to BNP

BNP's marketing partners and distributors. Notwithstanding the foregoing, in the
event that (i) BNP or any  Affiliate of BNP shall  appoint any of the  companies
listed on Exhibit E attached  hereto as a marketing  partner or  distributor  of
paclitaxel  injection,  or (ii) BNP  shall  become  an  Affiliate  of any of the
companies listed on Exhibit E attached  hereto,  then NaPro shall have the right
to terminate the License upon written  notice to BNP, and upon such  termination
by NaPro the License shall be of no further  force or effect;  provided that BNP
may enter  into any other type of  arrangement  with such  companies,  including
without  limitation,  arrangements  for the supply of Paclitaxel or arrangements
for the contract manufacture of paclitaxel injection.

                  (d) Prosecution of NaPro Patent.  NaPro shall, through counsel
of its own choosing and at its own expense,  take all reasonable  steps to file,
prosecute  and  maintain  the  NaPro  Patent  in all  countries  within  the BNP
Territory where such patent is pending,  whether by means of patent  cooperation
treaties or otherwise. NaPro agrees to promptly provide BNP's patent counsel, in
such  period of time as shall  accord  BNP and its patent  counsel a  reasonable
period of time for review  and  comment to the  extent  possible,  given  filing
deadlines,  with a copy of all  filings  related  to the  NaPro  Patent  in such
countries  prior to the time any such filings are made.  To the extent  possible
given filing  deadlines,  BNP and its patent  counsel  shall be provided with an
opportunity  to  comment  on all such  filings  and  NaPro  shall  consider  all
reasonable comments made by BNP and its patent counsel received in time for such
comments to be  incorporated  into such filings.  In addition to the  foregoing,
NaPro agrees to promptly provide BNP's patent counsel with copies of all papers,
specifications,  amendments,  replies,  official actions and other documents and
correspondence with the patent offices of such countries relating to the filing,
prosecution and maintenance of the NaPro Patent, including,  without limitation,
copies of each patent  application filed in the patent offices of such countries
and each patent that issues  thereon with respect to the NaPro  Patent.  Neither
BNP nor any of its Affiliates shall have the right to enforce the NaPro Patent.

     (e) Reserved  Patents.  Other than the NaPro Patent,  BNP  acknowledges and
agrees that nothing in this  Agreement  grants BNP or any of its  Affiliates any
rights under or to

#388043
                                                         5

<PAGE>






any patents or patent applications owned now or in the future by NaPro or any of
its Affiliates, including without limitation the Reserved Patents.

         5. Outstanding  Receivable.  BNP shall make a payment to NaPro equal to
one million  dollars  ($1,000,000)  in full  satisfaction  of all amounts due to
NaPro under the Prior Agreement,  including all outstanding  unpaid invoices for
Product.  Such  payment  shall be made  within two (2)  business  days after the
Effective  Date by wire transfer of  immediately  available  funds to an account
designated by NaPro.

         6.       Supply of Product.

     (a) Cancellation of Purchase Orders and Forecasts. All outstanding purchase
orders for Product and forecasts  under the Prior  Agreement are canceled in all
respects as of the Effective Date.

                  (b)      Supply of Product.

     (i) Delivery of Product.  NaPro shall deliver a total of *[TEXT  REDACTED]1
of Product to BNP in accordance  with the delivery  schedule  attached hereto as
Exhibit  B.  NaPro  acknowledges  that (i) BNP has paid for and is the  owner of
*[TEXT  REDACTED] of such Product,  (ii) that the remaining  *[TEXT REDACTED] of
such Product has been processed to a  semi-finished  state  exclusively for BNP,
(iii) that BNP has already paid to NaPro *[TEXT  REDACTED] for *[TEXT  REDACTED]
of such  semi-finished  Product and that BNP is the owner of such  semi-finished
Product; and (iv) that BNP has already paid to NaPro *[TEXT REDACTED] for *[TEXT
REDACTED]  of such  semi-finished  Product,  which price  includes the price for
converting such semi-finished  Product to finished Product,  and that BNP is the
owner of such Product.  Pending delivery of such Product to BNP, NaPro agrees to
maintain such Product  segregated  from its other inventory and to identify such
Product  as  owned  by BNP,  in a  manner  reasonably  acceptable  to BNP.  Upon
reasonable  notice to NaPro,  BNP shall have the right to inspect  such  Product
during normal  business hours to ensure NaPro's  compliance with this paragraph.
For purposes of notifying  NaPro's creditors of BNP's ownership of such Product,
on the  Effective  Date NaPro will execute and deliver to BNP a UCC-1  financing
statement in a form  reasonably  acceptable  to BNP.  NaPro shall also take such
further actions and execute such further documents as BNP may reasonably request
to secure BNP's interest in such Product.

     (ii)  Force  Majeure.  NaPro  shall not be liable to BNP in the event  that
performance of its supply obligations  hereunder shall be prevented by events of
force majeure,  including  without  limitation  acts of God, acts of government,
accident,  fire,  delay or destruction of means of transport or other  disaster,
but NaPro  shall use  reasonable  efforts  to avoid or remove  the cause of such
nonperformance and shall continue performance hereunder with the utmost dispatch
whenever such cause is removed.

     (iii) Payment for Product. The first *[TEXT REDACTED]1 of Product delivered
by NaPro pursuant to Section 6(b)(i) shall require no additional payment by BNP.
For the remaining *[TEXT REDACTED] of Product to be delivered to BNP pursuant to
Section 6(b)(i),  the ex works price to convert such Product from  semi-finished
to finished  state shall be *[TEXT  REDACTED].  NaPro shall invoice such Product
upon  delivery ex works  Boulder (or other NaPro  Facility)  and payment for the
Product  shall be due  thirty  (30)  days  net.  Payments  shall be made by wire
transfer to the account specified by NaPro from time to time.

     (iv)  Release  from  Escrow.  In addition to the payments for Product to be
made by BNP pursuant to Section  6(b)(iii),  upon  delivery of Product to BNP in
the  quantities set forth on Exhibit B, BNP shall release from escrow the amount
of money set forth on such Exhibit B corresponding to such Product quantity.  In
the  event  that  NaPro  fails to  supply  Product  according  to such  delivery
schedule,  then  BNP may  issue  NaPro  a  notice  of  default  of  this  supply
obligation.  If (a) ninety (90) days  following  such notice,  NaPro  remains in
default,  or (b) NaPro is unable to supply  Product due to a force majeure event
that  lasts for a period of six (6)  months,  BNP may cancel  the  remainder  of
scheduled deliveries. BNP shall be entitled to immediately recover the remaining
escrow amount,  and NaPro shall,  within two business days after cancellation of
the  remaining  delivery  schedule,  pay to BNP  any  Loss  not  covered  by the
remaining  escrow amount.  The maximum Loss which NaPro shall be responsible for
in connection  with failure to supply Product as set forth in Exhibit B shall be
*[TEXT REDACTED] not delivered.

     (v) Manufacture of Product.  NaPro shall  manufacture or have  manufactured
Product  according to the  Specification  and in accordance  with all applicable
United States laws and  regulations,  including GMP  regulations  as applicable.
NaPro  warrants and  guarantees  that the Product shall meet the  Specification.
With each lot of Product supplied by NaPro to BNP, whether manufactured by NaPro
or otherwise,  NaPro shall submit to BNP an appropriate  certificate of analysis
confirming compliance with the Specification.

reasonable times, but not more often than once a year (except if a deficiency or
defect or other similar problem is detected, in which event reinspections may be
conducted as often as reasonably  necessary to ascertain that such deficiency or
defect or other such problem has been cured), afford BNP's Quality Assurance and
Quality  Compliance  representatives  (which are not manufacturing or production
personnel)  (hereinafter  referred to "Q&A  Representatives")  access to NaPro's
premises where the Product manufactured for BNP is being tested and manufactured
and make  available  books,  records and  documents  as  reasonably  required to
ascertain  that  the  Product  is  being  manufactured  in  accordance  with the

manufactured and shall promptly  provide BNP with copies of all  correspondence,
reports,  notices,  findings and other material pertinent to such inspections or
otherwise  relating to the  production  of  Paclitaxel,  as they are received or
produced by or on behalf of NaPro from or to the FDA or any other federal, state
or foreign governmental or regulatory authority. Without limiting the generality
of the foregoing, NaPro shall promptly provide BNP with copies of all regulatory
letters,  warning letters,  and letters of adverse findings received by NaPro or
any of its agents relating to the production, use or sale of Paclitaxel supplied

information  that  discloses  NaPro  intellectual   property  or  trade  secrets
(including,  without  limitation,  information  relating to the  production  and
manufacture of Paclitaxel) shall be redacted and not provided to BNP;  provided,
however,  that complete  full copies of such  materials  without such  redaction
shall  be  made   available   for  review   (but  not   copying)  by  BNP's  Q&A
Representatives at NaPro's offices.

            (vii)    Shipping.  NaPro shall deliver the Product Ex works NaPro's
manufacturing  facility.  NaPro shall  cooperate with BNP to ship the Product to
BNP or the  finisher  designated  by BNP or to  such  other  location  as  BNP's
purchase  order shall  specify,  at BNP's  expense.  Risk of loss to the Product
shall pass upon delivery to BNP's common  carrier.  BNP shall be responsible for
obtaining any necessary import or export licenses to ship the Product. Following
delivery  of the  Product to BNP,  BNP shall  forthwith  check a  representative
sample of the Product for  conformity to the  Specification  and inform NaPro by
written notice of any damaged or otherwise  defective  Product supplied by NaPro
hereunder and shall, upon the request of NaPro,  return the damaged or defective
Product to NaPro and the  reasonable  cost of return shall be borne by NaPro and
NaPro shall as soon as practicable replace the damaged or defective Product free
of any  additional  charges,  provided that such damage or defect shall not have
been caused by BNP or the shipper to BNP.

                (viii)   Additional Product.  At the request of BNP, NaPro shall
manufacture and sell to BNP up to *[TEXT REDACTED]1 of Product containing *[TEXT
REDACTED] to be mutually  agreed upon by NaPro and BNP at a price to be mutually
agreed upon between the parties.

             (ix)     *[TEXT REDACTED].  NaPro shall continue its ongoing *[TEXT
REDACTED]  for Product  and provide BNP with the results of such study,  and BNP
shall  maintain  the  results  of  such  study  in  confidence  pursuant  to the
provisions of Section 7 hereof.

                  (c) Restriction on Sale of Product.  Without the prior written
consent  of  NaPro:  (i) BNP shall not sell any  product  containing  Paclitaxel
supplied by NaPro within the Exclusive Faulding  Territory,  and (ii) during the
time in which NaPro is a supplier of Product to BNP  pursuant to this  Agreement
or the  License  is in full  force and  effect,  BNP  shall not sell  paclitaxel
injection in the Exclusive Faulding Territory.

                  (d) Right of Reference.  BNP and, to the extent necessary, its
marketing  partners and distributors,  shall have the right to reference NaPro's
Drug Master File in connection with the sale of paclitaxel  injection containing
Product  supplied by NaPro under the Prior  Agreement  or this  Agreement.  This
right shall terminate upon the completion of BNP's sale of paclitaxel  injection
containing  Product  supplied by NaPro.  In the United States,  Canada,  and the
European  Union,  BNP and  its  Affiliates  shall  endeavor  to sell  paclitaxel
injection  containing NaPro Paclitaxel prior to selling  Paclitaxel  supplied by
other  sources.  While this right is in effect,  NaPro shall  maintain  its Drug
Master File in the United  States,  Canada and the  European  Union.  NaPro will
consult  with and  assist  BNP as  reasonably  requested  in  interactions  with
regulatory  authorities within the United States, Canada, and the European Union
in connection with NaPro's Drug Master File and BNP's pending  applications  for
Registration  in such  countries.  NaPro shall further  provide such letters and
documents  to such  regulatory  authorities  as are  required  to respond to the
questions and comments of such  regulatory  authorities  regarding  NaPro's Drug
Master File and BNP's pending applications for Registration in such countries as
will  enable BNP to make  reference  to NaPro's  Drug  Master File in support of
BNP's  submissions  or filings with said  authorities  and as will enable BNP to
respond to questions and comments of such regulatory  authorities  regarding the
portions of such applications  which contain  information  provided by NaPro, to
the extent such  documents or information  are in the  possession of NaPro.  BNP
shall pay NaPro's out-of-pocket costs for such assistance.  NaPro shall not make
any  amendments  to its Drug Master File which would require an amendment to any
of BNP's  regulatory  applications  or otherwise  require BNP to make any filing
with any  regulatory  authority  until after such amendment has been approved or
such filing

Registrations  or INDs which was  provided to Faulding  in  accordance  with the
Prior Agreement prior to the Effective Date, if any, solely within the Exclusive
Faulding Territory and solely for the purposes of obtaining Registrations within
the Exclusive  Faulding  Territory.  Faulding shall not be permitted to disclose
any such  information  to NaPro or any Third  Party  except to (i)  governmental
regulatory  authorities  in  connection  with  any  applications  for  an IND or
Registration for paclitaxel  injection and any applications for import or export

identified  in  Section A of Exhibit  C-1 to any Third  Party  which,  itself or
through an Affiliate, manufactures bulk Paclitaxel.

                  (f)   Precautions.   BNP  shall   maintain  the  BNP  Retained
Information as confidential,  and protect the same from misuse,  espionage, loss

                  (g) Equitable Remedies. In the event of a breach or threatened
breach by a party of the provisions of this Section 7, the  non-breaching  party
shall  be  entitled  to an  injunction  restraining  the  breaching  party  from
disclosing, in whole or in part, such Confidential  Information.  Nothing herein
shall be construed as  prohibiting  the  non-breaching  party from  pursuing any
other remedies available to it for such breach or threatened  breach,  including

make any such public statements  without the prior written approval of the other
party,  except (1) either  party may make public  statements  (other than in the
form of a press release) to the extent such  statements are consistent  with the
Initial Release and do not disclose any  information  which was not disclosed in
the Initial  Release or is not  publicly  available  as a result of a disclosure
made pursuant to clause (2) of this paragraph; and (2) to the extent required by

                                                 ESCROW AGREEMENT

                  THIS ESCROW  AGREEMENT (this  "Agreement"),  dated as of March

("NaPro"),  Baker Norton  Pharmaceuticals,  Inc., a Florida corporation ("BNP"),

                  WHEREAS,  NaPro, BNP, IVAX Corporation,  a Florida corporation
("IVAX") and D&N Holding Company, a Delaware  corporation ("D&N") are parties to
that  certain   Termination   Agreement   dated  as  of  the  same  date  hereof
("Termination  Agreement"),  pursuant  to which BNP has agreed,  inter alia,  to
deposit two million  dollars  ($2,000,000)  in an escrow  account for release to
NaPro upon certain events set forth in such Termination Agreement; and

                  WHEREAS,  this  Agreement is being entered into in conjunction
with the Termination Agreement so as to govern the administration of such escrow
account;

                  NOW,  THEREFORE,  for good  and  valuable  consideration,  the
receipt and  sufficiency  of which are hereby  acknowledged,  the parties hereto
agree as follows:

     1.  Definitions.  All  capitalized  terms used and not defined herein shall
have the meanings ascribed to such terms in the Termination Agreement.

                  2.       Deposit of Funds.

     (a) Deposit.  BNP shall deliver herewith to the Escrow Agent the sum of two
million  dollars  ($2,000,000)  by means of wire transfer.  Such amount plus any
interest thereon,  products and proceeds thereof, and any such amounts remaining
after  disbursements made pursuant to the terms and conditions of this Agreement
are hereinafter referred to as the "Deposit".  The Escrow Agent hereby agrees to
hold the  Deposit in a  separate  and  distinct  interest-bearing  account  (the
"Escrow  Account") as a trust fund.  Except as set forth in Section 5(b) hereof,
the Deposit shall not be subject to any lien,  attachment,  trustee process,  or
any other  judicial  process of any creditor of any party  hereto,  and shall be
used solely for the purposes of and subject to the terms and  conditions of this
Agreement.

and having a maturity  of not more than  thirty  (30)  days;  (iv) money  market
mutual  funds with daily  liquidity  that invests  primarily in the  Permissible
Investments;  and (v) such other  investments as BNP and NaPro may agree upon in
writing,  provided  that the Escrow  Agent has been duly  notified in writing of
such  agreed  upon  investments.  In the event  that the  Escrow  Agent does not

shall, pending alternative investment  instructions,  invest the funds in mutual
funds,  including  First  American  Mutual  Funds,  investing in  securities  or
obligations that are Permissible Investments under this Agreement, including any
mutual  fund from which the Escrow  Agent or any of its  Affiliates  may receive
compensation.

                  3.       Disbursement of Deposit.

     (a) Disbursement on Delivery of Product.  Upon shipment of Product by NaPro
to BNP,  NaPro  shall  provide  the Escrow  Agent and BNP with (i) a copy of the
Certificate  of Analysis  for the shipped  Product,  (ii) a copy of the shipping
documents for such Product,  and (iii) a document  signed by an officer of NaPro
certifying the amount  shipped and the total quantity of Product  shipped to BNP
since the date of this Agreement.  The Escrow Agent shall forward a copy of such
documents  to BNP by  facsimile.  In the event BNP does not  provide  the Escrow
Agent with a written  objection to  disbursement  of the Deposit within ten (10)
days of receipt of the foregoing  information by BNP from the Escrow Agent,  the
Escrow Agent shall disburse to NaPro the amount of the Deposit  corresponding to
the  amount  of  Product  shipped  by NaPro to BNP,  as set  forth on  Exhibit A
attached hereto. Such disbursement shall be made by wire transfer of immediately
available funds.

     (b)  Disbursement  on  Cancellation.  Upon  cancellation  of the  remaining
scheduled  deliveries  of Product by BNP  pursuant  to Section  6(b)(iv)  of the

such cancellation notice to NaPro by facsimile. In the event that NaPro does not
provide the Escrow Agent with a written objection to disbursement of the Deposit
within  ten (10) days of receipt  of the  cancellation  notice by NaPro from the
Escrow Agent,  the Escrow Agent shall  disburse to BNP the entire balance of the
Deposit.  Such  disbursement  shall  be  made by wire  transfer  of  immediately
available funds to an account designated by BNP.

requirements,  the  Escrow  Agent is  hereby  directed  to  allocate  investment
earnings on the Deposit to NaPro,  and to pay the  investment  earnings to NaPro
monthly as they are earned.

                  4.  Termination.  This Escrow  Agreement  shall  automatically
terminate  on the date on which all  amounts  in the  Escrow  Account  have been
distributed pursuant to the provisions of Section 3 hereof;  provided,  however,
if the  Deposit  is not  distributed  pursuant  to Section 3 hereof on or before
March 20, 2013,  the Escrow Agent is instructed  to release and then  distribute
the Deposit in the Escrow Account to BNP. Upon release of the Deposit hereunder,
the  Escrow  Agent  shall  be  relieved  of all  liability  arising  under  this
Agreement.

                  5.       The Escrow Agent.

     (a) Escrow Agent's Conduct. In performing its duties hereunder,  the Escrow
Agent may, without liability for sufficiency,  correctness, or validity thereof,
rely on  statements,  writings,  or  signatures  furnished  to it by the parties
hereto, or on any other evidence deemed by the Escrow Agent to be reliable.  The
Escrow Agent's duties shall be limited to the  safekeeping of the Escrow Account
and  discharge of same in  accordance  with the written  instructions  described
above.  The Escrow Agent undertakes to perform only such duties as are expressly
set forth herein,  and no implied duties or obligations  shall be read into this
Agreement with respect to the Escrow Agent. The Escrow Agent shall not be liable
for any act it may do or omit to do as agent,  while acting in good faith and in
the  exercise  of its own best  judgment.  Any act done or omitted by the Escrow
Agent on the advice of its own attorneys  shall be deemed  conclusively  to have
been done or omitted in good faith. The Escrow Agent shall have the right at any
time to consult with counsel on any question  arising under this Agreement.  The
Escrow  Agent  shall incur no  liability  for any delay  reasonably  required to
obtain the advice of counsel. The Escrow Agent shall not be a party to and shall
not be bound  by any  agreements  related  hereto  other  than  this  Agreement.
Furthermore,  the  Escrow  Agent  shall  have no duty to know or  determine  the
performance  or  nonperformance  of any provision of any  agreement  that exists
between BNP and NaPro and/or any other third parties.

     (b) Escrow  Agent's Fees and Expenses.  The Escrow Agent shall receive fees
for  performance  of this  Agreement,  and shall be  entitled  to the payment of
reasonable out-of-pocket expenses, including reasonable attorneys' fees, if any,
incurred in connection  with  performing  its duties  hereunder,  which fees and
expenses shall be billed directly to and paid by NaPro, it being understood that
the  payment  of such fees and  expenses  shall be deemed to satisfy in full any
obligations  on the part of the parties hereto with respect to the Escrow Agent.
The Escrow Agent's fees for the  performance of ordinary  duties are as follows:
(i)  setting up fees equal to five  hundred  dollars  ($500),  (ii)  annual fees
(payable in  advance,  per year or any portion  thereof)  equal to one  thousand
dollars  ($1000),  billed  quarterly at two hundred fifty dollars  ($250) or any
portion thereof, and (iii) fifty dollars ($50) per buy or sell of any investment
other than First American Mutual Fund investments. The Escrow Agent shall have a
first and prior lien on the Deposit to secure its indemnification and payment of
fees and expenses. In the event payment is not received promptly from NaPro, the
Escrow Agent is authorized to deduct fees and expenses first from the investment
earnings otherwise payable to NaPro, and then from any remaining Deposit.

     (c) New Escrow  Agent.  The Escrow Agent may,  upon ten (10)  business days
written  notice to each of NaPro  and BNP,  resign  and  cease  acting as Escrow
Agent.  NaPro and BNP may at any time  remove the  Escrow  Agent with or without
cause by an  instrument  signed  by BNP and NaPro and  delivered  to the  Escrow
Agent. If the Escrow Agent shall resign or cease to act as Escrow Agent, BNP and
NaPro  shall  mutually  agree upon a  successor,  which will be deemed to be the
Escrow Agent for all purposes of this  Agreement.  The Escrow Agent shall,  upon
selection  of a  successor,  deliver  the amount in the  Escrow  Account to such
successor  and shall be relieved from any further  liability and  responsibility
under this Agreement.

     (d) Protection of Escrow Agent. In  consideration of the acceptance of this
escrow by the Escrow Agent, the parties hereby agree, jointly and severally, for
themselves and their successors and assigns,  that (i) any party may examine the
books and records evidencing the Escrow Account at any time at the office of the
Escrow  Agent  during  the  Escrow  Agent's  normal  business  hours;   (ii)  no
assignment,  transfer,  conveyance,  or  hypothecation  of any right,  title, or
interest of any party or its  successor  in and to the Escrow  Account  shall be
binding  upon the  Escrow  Agent,  unless  and until  written  evidence  of such
assignment,  transfer,  conveyance, or hypothecation in form satisfactory to the
Escrow  Agent shall be filed with and  accepted by the Escrow  Agent;  (iii) the
Escrow Agent shall not be personally  liable for any act it may do or omit to do
as Escrow Agent under this Agreement,  unless resulting from gross negligence or
wilful  misconduct;  (iv) the Escrow Agent may  disregard any and all notices or
warnings given by any of the parties hereto (except notices expressly envisioned
in this Escrow  Agreement),  or by any other  person or entity,  excepting  only
orders or process of court,  and is hereby  expressly  authorized to comply with
and obey any and all  orders,  judgments,  or  decrees  of any court  reasonably
believed by the Escrow Agent to have  jurisdiction of the subject matter and the
parties,  and in case the Escrow  Agent obeys or  complies  with any such order,
judgment,  or  decree  of any such  court it shall  not be  liable to any of the
parties  hereto or to any other  person or entity by reason of such  compliance,
notwithstanding any such order, judgment, or decree being subsequently reversed,
modified,  annulled, set aside or vacated, or found to have been entered without
jurisdiction;  and (v) NaPro and BNP shall jointly, but not severally, indemnify
and hold the Escrow Agent harmless as to any loss,  claim,  damage, or liability
incurred  by the  Escrow  Agent to any  other  person or entity by reason of the
Escrow Agent's having acted as Escrow Agent hereunder, or in connection herewith
(collectively,  "Losses"),  other than those  Losses  resulting  from the Escrow
Agent's gross negligence or willful misconduct.

     (e) Interpleader. In the event of any disagreement or uncertainty regarding
the determination of the arbitrators pursuant to Section 6(f) of this Agreement,
the  interpretation  of this Agreement,  the rights and obligations set forth in
this Agreement,  or the propriety of any action  contemplated to be taken by the
Escrow Agent hereunder,  the Escrow Agent may, in its sole  discretion,  file an
action in interpleader to resolve such  disagreement or uncertainty.  The Escrow
Agent shall be entitled to recover from the parties hereto all  reasonable  fees
and expenses in connection with the filing of any such action.

     (f)  Reports.  The Escrow  Agent shall  furnish  NaPro and BNP with written
reports  on a monthly  basis as to the amount of funds  contained  in the Escrow
Account,  the investments  contained in the Escrow Account,  and describing each
transaction  made  with  respect  to  this  Agreement  during  the  term of this
Agreement.

For Immediate Release

                          NAPRO AND IVAX TERMINATE PACLITAXEL
                          DEVELOPMENT AND MARKETING AGREEMENT

Boulder,  Colo.,  March 19, 1998 - NaPro  BioTherapeutics,  Inc. (Nasdaq:  NPRO)
today  announced  that NaPro and Baker  Norton  Pharmaceuticals,  Inc., a wholly
owned  subsidiary  of  IVAX  Corporation  (AMEX:  IVX),  have  terminated  their
paclitaxel development and marketing agreement dating from 1993.

Under terms of the  termination  agreement,  IVAX will  receive a  royalty-free,
limited,   non-exclusive  license  to  NaPro's  pending  patents  for  a  stable
formulation of paclitaxel in the United  States,  Europe and certain other world
markets.  In return,  NaPro will  receive a cash  payment  of  approximately  $6
million, additional payments of up to approximately $6.4 million contingent upon
the issuance of the patents in certain  jurisdictions,  and the return of IVAX's
approximate  1.1 million  shares of NaPro common  stock.  NaPro will continue to
supply IVAX an agreed upon amount of paclitaxel.

"This agreement frees both IVAX and NaPro to separately  pursue  registration of
paclitaxel  around the world, and allows both parties to form other  alliances,"
said Sterling Ainsworth, NaPro President and Chief Executive Officer.

NaPro  BioTherapeutics,   Inc.,   headquartered  in  Boulder,   Colorado,  is  a
biopharmaceutical  company focused on the development,  production and licensing
of complex natural-product pharmaceuticals.

Except for the historical  matters  contained  herein,  statements in this press
release are forward looking and are made pursuant to the safe harbor  provisions
of the Securities  Litigation  Reform Act of 1995.  Investors are cautioned that
forward looking statements involve risks and uncertainties  which may affect the
company's  business and prospects,  including the risk that the  transaction may
not close, and certain economic,  competitive,  governmental,  technological and
other  factors  discussed in NaPro's  filings with the  Securities  and Exchange
Commission.
