Item 5. Other Events

         On February 19, 1999, NeoPharm, Inc. (the "Company") entered into a
license agreement (the "License Agreement") with Pharmacia & Upjohn Company
("P&U") with respect to the Company's Liposomal Encapsulated Paclitaxel ("LEP")
and Liposomal Encapsulated Doxorubicin ("LED"), two of the Company's cancer
products. The License Agreement provides P & U with exclusive worldwide rights
to market and sell LED and LEP. Subject to future agreements and payments, the
Company and P & U have also agreed to work together to identify and develop
additional drugs in P&U's oncology portfolio using NeoPharm's proprietary
liposome technology.

         Under the terms of the License Agreement, P & U agreed to make an
up-front payment to Company, which payment was received by the Company on
February 26, 1999. P & U has also agreed to provide all required funding for the
continuing clinical development of LEP and LED and to make subsequent milestone
payments as specified goals are achieved. In addition P & U will pay the Company
a royalty on all sales outside the United States and, within the United States,
the Company may elect a co-promotion arrangement under which profits will be
split between the two parties.

         In connection with the License Agreement, the Company has also entered
into a Stock Purchase Agreement with P&U providing for P&U's purchase of
$8,000,000 of the Company's common stock based on 110% of the average closing
price per share of the Company's common stock as reported on the American Stock
Exchange during the 60-day period preceding the date upon which the Company
shall receive notification from the U.S. Food & Drug Administration ("FDA") that
the Company's IND filings for LED and LEP have been effectively transferred to
P&U. Assuming that the FDA notification is received within 60 days, the Company
anticipates issuing the above described shares of its common stock on or before
April 20, 1999. The sale of the shares will not be registered under the
Securities Act of 1933, as amended (the "Securities Act"), and will be made in
reliance on Section 4(2) of the Securities Act and Rule 506 of Regulation D. In
addition, P & U and the Company will enter into a registration rights agreement
providing P & U with certain demand and piggyback registration rights with
respect to the shares acquired from the Company.

         6.5 ROYALTY REDUCTION ON SALES OF PRODUCTS; RIGHT TO SUPPLY.

         (a) PNU shall use all commercially reasonable efforts so that the Cost
of Goods Sold plus royalties does not exceed *** % of Net Sales of the LEP or
LED Products, respectively, in any year. NeoPharm agrees to reduce the royalties
for any LEP Product sold or for any LED Product sold so that, in either case,
the total of Cost of Goods Sold plus royalties shall not exceed *** % of Net
Sales of LEP Products or LED Products, as the case may be, in any year.

         (b) NeoPharm shall have the right to supply LEP or LED to PNU, its
Affiliates or Sublicensees if NeoPharm can supply such Product of the same
quality and specification and at a lower cost than PNU or any Third Party
supplier.

         6.6 COMPULSORY LICENSE. PNU shall use all commercially reasonable
efforts to prevent or avoid any Third Party from obtaining or being granted a
Compulsory License, and to the extent that a Third Party does obtain or is
granted a Compulsory License, PNU will use all commercially reasonable efforts
to limit or reduce the scope or applicability of such Compulsory License. If,
notwithstanding PNU's use of commercially reasonable efforts, any Third Party
obtains a Compulsory License in any country, then NeoPharm or PNU (whoever has
first notice) shall promptly notify the other party. If the royalty rate payable
by the grantee of the Compulsory License is less than the above royalty rates,
the above royalty rates shall be reduced to such lower rate in the subject
country for so long as sales are made pursuant to the Compulsory License.

         6.7 COMBINATION SALES. In the event any of the Products are packaged or
combined with any other products for sale in any country, the royalties payable
with respect to sales of such Product shall be calculated on the price of the
Product as if such Product had continued to be sold alone.

         6.8 PAYMENTS. Royalties or profit participation payable hereunder will
be paid to NeoPharm not later than forty-five (45) calendar days following the
end of each calendar quarter and each such payment shall be accompanied by a
report in writing showing the period to which such payment applies, the amount
billed to unaffiliated Third Parties for Products during such calendar quarter,
the deductions from the amount billed to arrive at Net Sales, the total Net
Sales for the period, the Cost of Goods Sold and the royalties due on such Net
Sales or the profit allocable to NeoPharm, as the case may be.

         6.9 CURRENCY OF PAYMENT. All payments to be made by PNU to NeoPharm
hereunder shall be made in U.S. Dollars. Net Sales outside the U.S. shall be

shall be converted quarterly into an amount in U.S. Dollars based on PNU's
internal exchange rates used in preparing PNU's consolidated earnings statements
for such quarter.

         6.10 SINGLE ROYALTY. Any royalties payable under Article VI will be
payable only once with respect to a particular unit of Product and will be paid
only once regardless of there being more than one NeoPharm Patent applicable to
such unit of Product.

         6.11 RECORDS. PNU shall keep for three (3) years from the date of each
payment of royalties complete and accurate records of Net Sales by PNU, its
Affiliates and sublicensees of each Product in sufficient detail to allow
royalties to be determined accurately. NeoPharm shall have the right for a
period of three (3) years after receiving any report or statement with respect
to royalties due and payable to obtain at its expense from the independent
certified public accountant used by PNU an audit of the relevant records of PNU
to verify such report or statement. PNU shall make its records available for
inspection by such independent certified public accountant during regular
business hours at such place or places where such records are customarily kept,
upon reasonable notice from NeoPharm, to the extent reasonably necessary to
verify the accuracy of the reports and payments. Such inspection right shall not
be exercised more than once in any calendar year nor more than once with respect
to sales in any given period, unless a subsequent inspection reveals
discrepancies which may have also occurred during such period. Such independent
certified public accountant shall report to NeoPharm only as to the accuracy of
the Net Sales computation and royalty payments. If the audit shows that PNU has
underpaid any royalties by five percent (5%) or more, for any period covered by
the audit, PNU shall, in addition to immediately remitting to NeoPharm the
amount of underpayment, (i) pay for the cost of such audit and (ii) pay interest
to NeoPharm at a per annum rate equal to 2% above the Prime Rate as announced
from time to time by Citibank, N.A. (the "Late Payment Rate") on such
underpayment from the date such amounts were accrued until the date such amounts
are paid. In the event the audit shows that PNU has overpaid any royalties due
to NeoPharm hereunder, PNU shall be allowed to deduct the amount of such
overpayment (plus interest on such overpayment at the Late Payment Rate from the
date of such underpayment) from the next royalty payment due to NeoPharm. The
independent certified public accountant agrees to hold in strict confidence all
information concerning royalty payments and reports, and all information learned
in the course of any audit or inspection, except to the extent necessary for
such party to reveal such information in order to allow NeoPharm to enforce its
rights under this Agreement or disclosure is required by law. The failure of
NeoPharm to request verification of any report or statement during the three (3)
year period shall be considered acceptance of the accuracy of such report, and
PNU shall have no obligation to maintain records pertaining to such report or
statement beyond the three (3) year period. The results of the inspection shall
be binding on both parties.

         6.12 WITHHOLDING TAXES. All amounts owing to NeoPharm on account of
royalties or profits as specified in this Agreement shall be paid net of all
applicable taxes, fees and other charges required to be withheld. PNU shall use
its commercially reasonable efforts to reduce the amount of any withholding
taxes and to promptly remit all refunds and rebates to NeoPharm.

         6.13 OTHER FORMS OF REMUNERATION. If PNU receives non-cash compensation
from sales of Products in a manner other than one for which royalties based on
Net Sales

 
                                       14

<PAGE>   17



would be the appropriate measure, such as compensation through a co-marketing or
joint venture arrangement, the parties will negotiate in good faith an
appropriate compensation arrangement by which NeoPharm will be equitably
remunerated.

                                  ARTICLE VII.
                                  CO-PROMOTION

         7.1 CO-PROMOTION. NeoPharm shall have the right in accordance with
Article VI, to co-promote the Products in the U.S. Territory under an
arrangement to be agreed upon between NeoPharm and PNU based upon the
methodology set forth in the Profit and Loss Schedule attached hereto as
Schedule 7.1 and upon the following terms:

         (a) NeoPharm's participation in the Net Profits shall be in proportion
to its monetary contribution to the promotion of each Product (which shall
include an allocation of sales representatives as needed) but in no event shall
NeoPharm's share of profits exceed *** % of the total Net Profits.

         (b) NeoPharm shall pay to PNU within sixty (60) days of notifying PNU
of its election to co-promote a Product in the U.S. Territory an amount equal to
PNU's development costs for such Product (which costs shall not exceed ***
percent of PNU's Development Costs throughout the Territory as calculated in
accordance with PNU's standard internal policies and procedures) multiplied by
NeoPharm's Net Profit percentage determined under Section 7.1(a) and multiplied
by a premium determined in accordance with *** hereto to reflect the development
risk incurred by PNU.

         (c) If NeoPharm exercises the Co-promotion Election, no royalty shall
become payable by PNU to NeoPharm with respect to sales of any Product subject
to such arrangement, in the U.S. Territory.

         (d) The co-promotion rights set forth herein are not sublicensable,
assignable or transferable by NeoPharm and shall not be sublicensed, assigned or
transferred without PNU's prior written consent. Without limiting the foregoing,
and except as may otherwise be agreed by the parties, in the event of a merger
with or acquisition by any third party (i) with interests in oncology, including
companies involved in cytotoxic compounds or products or (ii) which is a clear
competitor of PNU in the oncology business, such consent will not be given, and,
PNU shall have the right to terminate the co-promotion arrangement.

         (e) In the event PNU terminates the co-promotion arrangement pursuant
to Section 7.1(d), PNU shall thereafter pay NeoPharm a royalty of (i) ***
percent on all sales of LED Products in the U.S. Territory for the remainder of
the otherwise applicable ten (10) year term and (ii) *** % on all sales of LEP
Products in the U.S. Territory for the duration that PNU has exclusive rights in
the NeoPharm Patents covering LEP.

         (f) If NeoPharm exercises the Co-Promotion Election, the parties will
negotiate in good faith to conclude a co-promotion agreement within ninety (90)
days of such election,

*** Confidential Treatment Requested
 
                                       15

specifying the rights and obligations of the parties. PNU shall have final
decision making authority in the event the parties are unable to agree except
with respect to NeoPharm's right to decide its monetary contribution and level
of profit participation as specified in Section 7.1(a).

                                  ARTICLE VIII.
               TECHNICAL ASSISTANCE; DEVELOPMENT EXPENSES; REPORTS

         8.1 FURTHER ASSURANCE. Without otherwise limiting the representations
and warranties of NeoPharm, NeoPharm shall use reasonable commercial efforts to
assist and enable PNU or any Affiliate or Sublicensee thereof to obtain and
confirm in PNU the rights granted to PNU pursuant to this Agreement to develop,
use, make and have made the Compounds and to develop, use, make, have made,
distribute, market, sell and have sold the Products and shall take all such
other actions as PNU may reasonably request to obtain and confirm in PNU such
rights. If NeoPharm, in connection with its reasonable commercial efforts,
shall, upon prior written request from, and subsequent written approval by, PNU,
incur any reasonable out of pocket expenses or costs ("Direct Costs") in
obtaining or confirming in PNU or any Affiliate or Sublicensee such rights, such
Direct Costs shall be promptly reimbursed by PNU except as may be provided in
Section 10.5 or Section 17.

         8.2 DEVELOPMENT COSTS AND TECHNICAL ASSISTANCE. All of the development
costs, clinical and pre-clinical, regulatory and manufacturing scale-up expenses
(including capital investments for equipment and any other manufacturing
facilities required) for the Products incurred after the date hereof, shall be
borne by PNU. To the extent PNU requests NeoPharm to provide personnel or
supplies or to take any other action in connection with the foregoing, PNU shall
reimburse NeoPharm for all reasonable out-of-pocket costs incurred therewith.

         8.3 REPORTS. PNU shall deliver to NeoPharm reports, at least quarterly,
providing NeoPharm with sufficient information so as to allow NeoPharm to be
adequately informed as to the strategic development of the Compounds and the
Products. In connection therewith, NeoPharm may request a meeting to discuss the
contents of the report.

                                   ARTICLE IX.
                              INTELLECTUAL PROPERTY

necessary to enable NeoPharm to exercise its rights under Section 6.5, NeoPharm
shall not have access to the database without PNU's prior written consent which
consent shall not be unreasonably withheld after expiration of the Agreement
Term. Upon PNU's request, NeoPharm shall promptly assist PNU, and shall use
commercially reasonable efforts to encourage its vendors and subcontractors to
assist PNU, in preparing and obtaining favorable review of IND's relating to the
Products and the foreign equivalents of such IND's. If PNU so desires, NeoPharm
shall transfer to PNU any IND's relating to the Products owned or Controlled by
NeoPharm.

         9.11 REGULATORY FILINGS. PNU or its Sublicensees shall be responsible
for the preparation of suitable applications for Regulatory Approval in any
country in the Territory and shall be the owner and party of record of all such
applications, including all NDAs. PNU shall solely determine those countries of
the Territory in which to file such applications. At PNU's request, NeoPharm

and package inserts for Products, NeoPharm as the licensor of the Compounds.
Notwithstanding the foregoing, if PNU reasonably believes, based on objective
information, that identifying NeoPharm or using the NeoPharm mark will have an
adverse impact on the image or commercialization of the Products, due to adverse
publicity relating to NeoPharm or its personnel, products or business or some
other event or circumstance, PNU will discuss the situation with NeoPharm and
may, after such discussion, discontinue identifying NeoPharm or using the
NeoPharm mark.

the amount of any actual or potential indemnification to be provided pursuant to
Section 17.2, such amount shall be paid by NeoPharm without any right to
reimbursement from PNU.

         10.6 NO THIRD PART EFFECT. Neither this Article X, nor any exercise of
rights or fulfillment of obligations under this Article X, shall affect by
itself any indemnification or contribution rights of either party against any
other party.

effectuate and carry out the purposes of this Agreement.

         13.2 COVENANT OF NEOPHARM. From and after the License Effective Date,

         (a) work in good faith with PNU to assure satisfactory arrangements for
the long term supply of bulk paclitaxel and cardiolipin.

         (b) not provide any rights to any Third Party with respect to the
Products, the Compounds and other compounds in the class known as taxanes and
anthracyclines within the Field of Use.

         (c) provide written notice to PNU of any Patent applications owned or
Controlled by NeoPharm arising after the License Effective Date claiming
inventions that may be useful or necessary in the LED Field of Use or the LEP
Field of Use, and all material information known to NeoPharm relating to the
prospects for issuance of NeoPharm Patents from such Patent applications and the
validity and enforceability of such NeoPharm Patents.

         13.3 COVENANTS OF PNU.

         (a) PNU shall use Reasonable Efforts to timely achieve the milestones
referenced in Sections 4.1 or 4.2 hereof and to introduce, promote, market and
sell the Products in the Territory and such efforts shall be consistent with
providing NeoPharm with the benefit of the royalty payments and/or co-promotion
of the Products as contemplated herein. PNU shall maintain adequate facilities,
Product inventory and personnel to ensure prompt handling and servicing of
customer inquiries and orders and prompt shipping and servicing of the Products.
For purposes of this section 13.3, "Reasonable Efforts" shall mean efforts and
resources commonly used in the research-based pharmaceutical industry for a
product at a

 
                                       27

similar stage in its product life taking into account the establishment of the
product in the marketplace, the competitiveness of the marketplace, the
proprietary position of the product, the regulatory structure involved, the
profitability of the product and other relevant factors. Such resources and
efforts shall be determined for a particular Product on a case-by-case basis;
and it is anticipated that the level of effort will change over time reflecting
changes in the status of the Product and the marketplace.

         (b)PNU CEASES TO MARKET OR SELL PRODUCT. Unless otherwise mutually 
agreed to by the parties, should PNU or its Affiliates or Sublicensees:

         (1)cease to market or sell a Product for more than one year other than
         because of legal or administrative actions causing the cessation of
         marketing, Force Majeure or bona fide business reasons (provided that
         PNU shall use Reasonable Efforts to avoid or eliminate any such action,
         condition or business reasons) in (i) the United States, (ii) the U.K.,
         Spain, Italy, France and Germany ("European Markets") or (iii) Japan;
         or

         (2) fail to launch a particular Product within one year from
         the occurrence of the latest to occur of the following events (if
         applicable in such countries): (m) issuance of a Product's NDA approval
         (or equivalent regulatory approval), (n) governmental price approval
         and approval for reimbursement or, (o) joint resolution of any other
         bona fide business reasons for delaying such launch, in (x) the U.S.,
         (y) the European Markets, or (z) Japan,

         then in either case, PNU shall have no further rights to the applicable
         Product in the countries where such cessation or failure to launch has
         occurred, and PNU shall have no further obligations for the applicable
         Product in the countries where such cessation or failure to launch has
         occurred, except such obligations which accrued prior to divestment
         from PNU of rights to the applicable Product.

         In the event rights to a Product are divested from PNU in (i) the U.S.,
         (ii) the European Markets, or (iii) Japan pursuant to this Section
         13.3(b) and upon NeoPharm's request, PNU shall immediately transfer the
         NDA approval (or equivalent regulatory approval) in the applicable
         countries to NeoPharm or to an appointee of NeoPharm, provide to
         NeoPharm all data in PNU's possession or control relating to that
         Product and take all such other actions as are necessary or useful to
         permit NeoPharm to obtain Regulatory Approvals to market the Product in
         the applicable countries. NeoPharm shall market the Product under its
         own tradenames or brands and shall not use PNU's tradenames or brands
         and NeoPharm shall pay to PNU a royalty on Net Sales of all such
         Products in the applicable countries at the same rate as PNU would have
         been required to pay NeoPharm.

         Failure by PNU to launch a Product or cessation of marketing or sale of
         a Product pursuant to this Section 13.3(b) shall not be considered a
         breach of this Agreement within the meaning of Article 15.

         For the avoidance of doubt, it is understood between the parties hereto
         that the provisions of this Section 13.3(b) shall not apply in the
         event that PNU or its Affiliates or Sublicensees cease to sell a
         Product for reasons related to the safety or efficacy of a Product.

         13.4 MAINTENANCE OF LICENSES FROM THIRD PARTIES. So as not to adversely
affect PNU's right to NeoPharm Patents and NeoPharm Know-How under this
Agreement, NeoPharm agrees during the Agreement Term: (a) not to take any
actions to terminate or restrict its rights under any Third Party license
agreements or other agreements which give rise to such rights, (b) to discharge
all of NeoPharm's obligations and responsibilities under any such Third Party
license agreements or other agreements, including without limitation, making all
required payments thereunder, (c) to notify PNU promptly of NeoPharm's receipt
of any notices of breach under any such Third Party license agreements or other
agreements, and (d) during the Agreement Term, NeoPharm will not knowingly
infringe any valid Third Party intellectual property rights in its conduct of
any activity related to this Agreement.

         13.5 MANUFACTURE AND SUPPLY OF COMPOUNDS. NeoPharm will deliver to PNU
such quantities of Compound as are required in order to meet the development
needs of PNU, at PNU's cost and expense.

                                  ARTICLE XIV.
                            CONFIDENTIAL INFORMATION

         14.1 OWNERSHIP. Without limiting the rights granted to and by the
parties under this Agreement, Confidential Information furnished hereunder by
either party to the other shall remain the sole property of the disclosing
party; provided, however, that upon NeoPharm terminating this Agreement pursuant
to Section 15.2 or PNU terminating this Agreement pursuant to Section 15.3, PNU
shall grant NeoPharm a non-exclusive license to the Confidential Information
that PNU furnished to NeoPharm hereunder. Data and inventions concerning the
Products developed or made during the Agreement Term shall be owned by the
developing or inventing party.

         14.2 CONFIDENTIALITY. Each party agrees that during the Agreement Term
and at all times thereafter, it shall use all commercially reasonable efforts to
keep, and cause its Affiliates and/or Sublicensees to keep, confidential all
Confidential Information, and neither party nor any of its Affiliates and/or
Sublicensees shall use or disclose the Confidential Information except as
expressly permitted in this Agreement. Each party acknowledges that the
Confidential Information is highly valuable, proprietary and confidential and
that any disclosure to any officer, employee, or agent of such party or any of
its Affiliates shall be made only to the extent necessary to carry out its
responsibilities under this Agreement and only if such officer, employee or
agent shall be bound by an Agreement to maintain such information in confidence.

         14.3 PUBLIC ANNOUNCEMENTS AND STATEMENTS. Neither NeoPharm nor PNU, nor
any Affiliate thereof, shall issue or cause publication of any press release or
other public announcement or public communication with respect to this Agreement
or the transactions contemplated hereby without the prior written consent of the
other party, which consent shall not be unreasonably withheld or delayed.
Neither party shall use the name of the other party in any public statement or
press release without the prior written approval of the other party, which
approval may not be unreasonably withheld or delayed; provided, however, that
both parties shall give the other party a minimum of five (5) business days to
review any such press release or other public statement. Notwithstanding the
foregoing, each party may make any disclosure which such party, in the opinion
of its counsel, is obligated to make pursuant to applicable law, in which case
such party shall still endeavor to give the other party an opportunity to review
such disclosure but shall not be obligated to do so if such disclosure must, in
the opinion of its counsel, be made without time for review. The failure of a
party to draft such disclosure in a timely fashion shall not be deemed a reason
to avoid submitting such disclosure to the other party hereto.

         14.4 PUBLICITY RELATED TO THE PROJECT. Subject to the other provisions
of this Agreement, PNU may disclose information generated by studies sponsored
by PNU, or disclose any conclusions based on such information, after giving
NeoPharm a reasonable opportunity to review and comment (but not approve) any
such disclosure. In addition, each Party may announce periodically whether Phase
I, II or III studies involving the Products are underway or to be initiated. Any
other disclosures of information arising from or related to this Agreement shall
be approved by each of the parties hereto, except to the extent such information
is publicly known through no fault of NeoPharm or PNU or either party is
required, on advice of counsel, to make public disclosure relating to the
Project pursuant to any law, rule or regulation of any governmental agency,
including without limitation the United States Securities and Exchange
Commission or any securities exchange on which securities of the disclosing
party are then listed, in which case a party shall be permitted to make such
required disclosure provided advance notice is first given to the other party.

         14.5 INVESTIGATOR PUBLICATIONS. Notwithstanding anything set forth in
this Agreement to the contrary, NeoPharm and PNU agree to use their best efforts
to cause investigators who conduct clinical studies of the Products sponsored by
PNU or NeoPharm, respectively, to agree to submit the results of their studies
and a draft of publication to PNU or NeoPharm, respectively for review a
reasonable period of time before submission to the publisher. PNU and NeoPharm
will share with each other the results of these studies and these drafts of such
publication as soon as practicable. Both parties understand that neither party
will have the right to approve or disapprove the publication.

         14.6 POST-APPROVAL USE. Notwithstanding anything set forth in this
Agreement to the contrary, following approval of the Products, PNU shall be
permitted to use and publicize information generated by the Project in
connection with the commercialization and promotion of the Products, together
with all of NeoPharm's clinical data and Non-clinical data related to the
Products, in accordance with applicable laws and regulations. Likewise, PNU is
free to use information generated by PNU outside the scope of the Project as it
sees fit.

         14.7 USE OF NAME AND TRADEMARKS. Unless specifically authorized by this
Agreement, neither Party shall use in any manner the names or trademarks of the
other Party without the express written consent of such Party.

                                   ARTICLE XV.
                              TERM AND TERMINATION

         15.1 AGREEMENT TERM; COUNTRY TERM(S). This Agreement may be terminated
early pursuant to Sections 15.2 and 15.3 hereof by terminating the Agreement
Term. This Agreement, as applicable in a specific country in the Territory, may
be terminated early in such country by terminating the applicable Country Term,
without affecting the Agreement Term or the other Country Terms.

         15.2 TERMINATION BY NEOPHARM. NeoPharm may terminate the Agreement Term
upon written notice to PNU at any time in the event of: (i) a material breach by
PNU or its Affiliates or its Sublicensees of this Agreement where such breach is
continuing for sixty (60) days (or thirty (30) days with respect to nonpayment
of a material amount due unless such amount is subject to a bona fide dispute
between the parties) after PNU has received written notice from NeoPharm of such
breach, specifying in reasonable detail the particulars of the alleged breach,
and such breach has not been cured within such sixty (60) day period (or thirty
(30) days with respect to nonpayment of a material amount due unless such amount
is subject to a bona fide dispute between the parties). In the event that such a
breach (other than the nonpayment of a material amount due unless such amount is
subject to a bona fide dispute between the parties) may not be reasonably cured
in sixty (60) days, then such cure period shall be extended provided PNU shall
demonstrate to NeoPharm's reasonable satisfaction that it is using all
commercially reasonable efforts to cure such breach. If NeoPharm terminates the
Agreement Term pursuant to this Section 15.2, PNU shall transfer back to
NeoPharm all rights to the NeoPharm Patents and NeoPharm Know-How granted to PNU
plus grant to NeoPharm a non-exclusive license (requiring payment to PNU of a
reasonable royalty rate) to any and all Improvements, enhancements, Confidential
Information, Other Information, NDAs, or the substantially equivalent approvals
in the respective countries owned or controlled by PNU which relate to the
Compounds, which license shall only allow NeoPharm to use such Improvements,
enhancements, Confidential Information, Other Information, NDAs, or the
substantially equivalent approvals in the respective countries in connection
with the Compounds. For the avoidance of doubt, upon NeoPharm's termination of
the Agreement Term pursuant to this Section 15.2, PNU's rights included in the
relevant licenses granted by NeoPharm to PNU hereunder shall immediately and
automatically revert to NeoPharm; provided, however, that PNU, with the consent
of NeoPharm, shall be entitled to complete the manufacture of any Product then
in progress and to sell any such completed Product, along with any Product then
in inventory, subject to payment of royalties pursuant to Article VI. Without
limiting the generality of the foregoing, all relevant licenses and sublicenses
granted by NeoPharm to PNU hereunder shall terminate automatically and PNU shall
promptly transfer to NeoPharm all related documents, materials and records in
its possession without retaining any copies thereof.

         15.3 TERMINATION BY PNU. PNU may terminate the Agreement Term upon
written notice to NeoPharm at any time in the event of: (i) a material breach by
NeoPharm or its Affiliates of this Agreement where such breach is continuing for
sixty (60) days after NeoPharm has received written notice from PNU of such
breach, specifying in reasonable detail the particulars of the alleged breach,
and such breach has not been cured within such sixty (60) day period; and (ii)
at any time, without penalty, provided that PNU shall not be entitled to refund
of any payments made to NeoPharm prior to such termination date. In the event
that a breach set forth in subclause (i) may not be reasonably cured in sixty
(60) days, then such cure period shall be extended provided NeoPharm shall
demonstrate to PNU's reasonable satisfaction that it is using commercially
reasonable effects to cure such breach. If PNU terminates the Agreement Term
pursuant to this Section 15.3, it shall transfer back to NeoPharm all rights to
the NeoPharm Patents and NeoPharm Know How granted to it plus grant to NeoPharm
a non-exclusive license (requiring payment to PNU of a reasonable royalty rate)
to any and all Improvements or enhancements owned or controlled by PNU which
relate to the Compounds, which license shall only allow NeoPharm to use in
connection with the Compounds. For the avoidance of doubt, upon PNU's
termination of the Agreement Term pursuant to this Section 15.3, PNU's rights
included in the relevant licenses granted by NeoPharm to PNU hereunder shall
immediately and automatically revert to NeoPharm; provided, however, that PNU,
with the consent of NeoPharm, shall be entitled to complete the manufacture of
any Product then in progress and to sell any such completed Product, along with
any Product then in inventory, subject to payment of royalties pursuant to
Article VI; and provided, further, that upon (or in lieu of) termination
pursuant to Section 15.3(i); PNU shall be entitled to all available legal and
equitable remedies (including, but not limited to, monetary damages and specific
performance) as a result of NeoPharm's material breach of this Agreement.

                                  ARTICLE XVI.
           RIGHTS AND DUTIES UPON TERMINATION OR EXPIRATION; REMEDIES

         16.1 MONIES PAID OR DUE.

         (a) Upon the termination or expiration of this Agreement and subject to
Section 17.5, each party shall have the right to retain all payments already
received from the other party pursuant to this Agreement, and each party shall
pay to the other all sums accrued hereunder which are then due.

         (b) The termination of this Agreement by PNU under Section 15.3(i) or
(ii) hereof shall terminate PNU's obligation to make any payments under this
Agreement that would accrue after, and are not due and payable at the time of,
the effective date of the termination.

         16.2 SURVIVAL OF RIGHTS. The termination or expiration of this
Agreement shall not affect the accrued rights and obligations of NeoPharm or PNU
arising under or out of this Agreement or Claims arising during the Agreement
Term, and the obligations relating to such Claims. In addition, any provision
required to interpret and enforce the parties' rights


                                       32

<PAGE>   35



and obligations under this Agreement shall survive to the extent
required for the full observation and performance of this Agreement by the
parties hereto. Notwithstanding any provision herein to the contrary, the rights
and obligations set forth in Sections 2.3, 6.2, 6.4, 6.11, 12.4 and 16.3 and
Articles XIV and XVII shall survive the expiration or termination of this
Agreement.

         16.3 TRANSITION UPON TERMINATION. If this Agreement is terminated by
NeoPharm pursuant to Section 15.2 or by PNU pursuant to Section 15.3(ii), PNU
shall upon termination cooperate with NeoPharm and/or its Affiliates to transfer
back to NeoPharm all title and interest in and to the NeoPharm Patents and
NeoPharm Know-How and any Improvements developed by PNU or its Affiliates to use
solely with the Products.

         16.4 REMEDIES. If either party shall fail to perform or observe or
otherwise breaches any of its material obligations under this Agreement, in
addition to any right to terminate this Agreement, the non-defaulting party may
elect to obtain other such equitable relief and remedies as shall be available
under applicable law.

                                  ARTICLE XVII.
                   INDEMNIFICATION AND LIMITATION OF LIABILITY

         17.1 INDEMNIFICATION BY PNU. In addition to any other rights NeoPharm
may have at law or in equity, PNU shall indemnify, defend and hold harmless
NeoPharm and its Affiliates, employees, agents, officers and directors, and
their successors and assigns (each, an "NeoPharm Indemnified Party"), from and
against any and all Claims which the NeoPharm Indemnified Party may incur,
suffer or be required to pay resulting from or arising out of: (i) the
marketing, distribution, promotion or sale of the Products by PNU, its
Affiliates or Sublicensees; (ii) the manufacture of the Products by PNU or its
Affiliates or Sublicensees or by a Third Party (other than an Affiliate of
NeoPharm) after the License Effective Date, except and unless in the case of
either (i) or (ii) any such claim arises out of the breach of any NeoPharm
representations, warranties or covenants hereunder or NeoPharm had knowledge as
of the License Effective Date that, based on facts in existence and
circumstances existing on the License Effective Date, the manufacture,
marketing, distribution, promotion or sale of the Products after the License
Effective Date would be likely to result in or create such Claims; and (iii) any
breach of any representation, warranty or covenant of PNU or its Affiliates or
Sublicensees in this Agreement or the Stock Purchase Agreement or any other
transaction documents.

         17.2 INDEMNIFICATION BY NEOPHARM. In addition to any other rights PNU
may have at law or in equity, NeoPharm shall indemnify, defend and hold harmless
PNU and its Affiliates and Sublicensees and their respective employees, agents,
officers and directors, and their successors and assigns (each, a "PNU
Indemnified Party"), from and against any and all Claims which the PNU
Indemnified Party may incur, suffer or be required to pay resulting from or
arising out of: (i) the manufacture or use of the Compounds or the Products by
NeoPharm or their Affiliates; (ii) any liability arising prior to the License
Effective Date in any way relating to any Compound or the Products, regardless
of the date of first assertion

                                       33
<PAGE>   36



of any Claim or action relating thereto; (iii) any material breach of any
representation, warranty or covenant by NeoPharm or any Affiliate in this
Agreement or the Stock Purchase Agreement or any other transaction documents; or
(iv) any infringement of the intellectual property rights of any third party
existing as of the date hereof as a result of the use and exploitation by PNU of
the NeoPharm Patents and the NeoPharm Know-How in connection with the
manufacture, use, marketing and sale of the Products in the Territory, except
that in no event shall NeoPharm be required to indemnify any PNU Indemnified
Party with respect to any Claims which have arisen out of or relate to any
future changes in dosage, administration or manufacture of the Compounds or the
Products from that set forth in the NeoPharm Patents or the NeoPharm Know-How
existing on the License Effective Date.

         17.3 PROCESS OF INDEMNIFICATION. Promptly after an indemnified party
becomes aware of any potential Liability hereunder, such party shall deliver
written notice to the indemnifying party stating the nature of the potential
Liability; provided, however, that the failure to give such notification shall
not affect the indemnification provided hereunder except to the extent the
indemnifying party is actually prejudiced as a result of such failure. The
indemnified party shall give the indemnifying party such information with
respect to the potential Liability as the indemnifying party may from time to
time reasonably request. The indemnifying party shall have the right to conduct
the defense of any suit or Claim related to the Liability if it has assumed
responsibility for the suit, Claim or other proceeding in writing; provided,
however, that if in the reasonable judgment of the indemnified party such suit,
Claim or other proceeding involves an issue or matter which could have a
material adverse effect on the business, operations or assets of the indemnified
party, the indemnified party may elect, at its own expense, to conduct a
separate defense thereof, but in no event shall any such election be construed
as a waiver of any indemnification rights such indemnified party may have under
this Article XVII, at law or in equity, or otherwise. If the indemnifying party
defends the suit or Claim, the indemnified party may participate in (but not
control) the defense thereof at its sole cost and expense; provided, however,
that the indemnifying party shall pay the reasonable fees and costs of any
separate counsel required for the indemnified party to the extent such
representation is due to a conflict of interest between the parties.

         17.4 SETTLEMENTS. Neither party may settle any Claim, action or
proceeding related to a Liability to a Third Party without the consent of the
other party, which consent shall not be unreasonably withheld or delayed, if
such settlement would impose any monetary obligation on the other party or
require the other party to submit to an injunction or otherwise limit the other
party's rights under this Agreement, and any payment made by a party in such a
settlement without obtaining such consent shall be at its own cost and expense.
Notwithstanding the foregoing, the indemnifying party will be liable under this
Article XVII for any settlement effected without its consent if the indemnifying
party has refused to acknowledge liability for indemnification hereunder and/or
declines to defend the indemnified party in any such Claim, action or proceeding
and it is determined by arbitration pursuant to Article XVIII hereof that the
indemnifying party was liable to the indemnified party for indemnification
related to such settlement.

         17.5 RIGHT OF SET-OFF. In addition to any other remedies any party may
have for indemnification under this Agreement or at law or in equity, any party
may set off against any amount otherwise due and yet unpaid to the other party
hereunder any amount owed by such first party to the other party under any
provision of this Agreement or any instrument or Agreement delivered pursuant
hereto, or otherwise; provided, however, any amounts owed to a party pursuant to
Claims under Sections 10.4, 17.1 or 17.2, shall not be set off against amounts
owed by such party until all appeals or other actions relating to such Claims
have been exhausted which result in that Claim being fixed and certain.

                                 ARTICLE XVIII.
                                  ARBITRATION

         18.1 RESOLUTION OF DISPUTES BY PARTIES' REPRESENTATIVES. The parties
recognize that a bona fide dispute as to certain matters may from time to time
arise during the term of this Agreement which relate to either party's rights or
obligations hereunder. In the event of the occurrence of such a dispute, either
party may, by written notice to the other, have such dispute referred to their
respective officer designated below or their successors, for attempted
resolution by good faith negotiations within thirty (30) days after such notice
is received.

Said designated officers are as follows:

         For NeoPharm - President

         For PNU - Senior Vice President for Global Business Management

         In the event the designated officers are not able to resolve such
         dispute within such thirty (30) day period, any party may invoke the
         provisions in Section 18.2 below.

         18.2 ARBITRATION. Except as expressly provided in Section 18.1, and
except for the right of either party to apply to a court of competent
jurisdiction for a temporary restraining order to preserve the status quo or to
prevent irreparable harm pending the selection and confirmation of a panel of
arbitrators in accordance herewith, any and all disputes arising out of or in
connection with the performance of this Agreement shall be finally settled by
arbitration in accordance with the rules of the American Arbitration
Association, except that each party will be entitled to select one (1)
arbitrator and the two (2) arbitrators so selected shall select a third
arbitrator and if they cannot agree, then the third arbitrator will be selected
by the American Arbitration Association. The arbitration shall be held in New
York, New York. The award rendered shall be final and binding upon the parties.
Judgment on any award may be entered in any court having jurisdiction over the
parties or their assets. To the extent any claims relate to the validity,
construction, scope, enforceability or infringement of any Patent, such claim
shall not be required to be submitted to arbitration hereunder and shall be
resolved by a court of competent jurisdiction. The costs of arbitration shall be
shared equally by the parties.

                                  MISCELLANEOUS

         19.1 FORCE MAJEURE. If the performance by any party of any obligation
under this Agreement is prevented, restricted, interfered with or delayed by
reason of Force Majeure, the party so affected shall, upon giving written notice
to the other party, be excused from such performance and shall not be in breach
of this Agreement to the extent of such prevention, restriction, interference or
delay, provided that the affected party uses its reasonable efforts to avoid or
remove such causes of non-performance and continues performance with the utmost
dispatch whenever such causes are removed. In the event of Force Majeure lasting
more than six (6) months (or which the parties acknowledge will last more than
six (6) months), the parties agree to meet and discuss how this Agreement can be
justly and fairly implemented under the circumstances.

including without limitation: (i) all SEC or National Association of Securities
Dealers, Inc. (the "NASD") registration and filing fees, including, if
applicable, the fees and expenses of any "qualified independent underwriter"
(and its counsel) that is required to be retained by any Holder of Registrable
Securities in accordance with the rules and regulations of the NASD, (ii) all

or blue sky laws (including reasonable fees and disbursements of one counsel for
any underwriters or Holder in connection with blue sky qualification of any of
the Registrable Securities) and compliance with the rules of the NASD, (iii) all
expenses of any Persons in preparing or assisting in preparing, word processing,
printing and distributing any Registration Statement, any Prospectus and any
amendments or supplements thereto, and in preparing or assisting in preparing,
printing and distributing any underwriting agreements, securities sales
agreements and other documents relating to the performance of and compliance

statement of the Company that covers any of the Registrable Securities pursuant
to the provisions of this Agreement, and all amendments and supplements to any
such Registration Statement, including post-effective amendments, in each case
including the Prospectus contained therein, all exhibits thereto and all
material incorporated by reference therein.

         (j) The term "Securities Act" means the Securities Act of 1933, as
amended.

         (k) The term "SEC" means the Securities and Exchange Commission.

2. Demand Registration.

         (a) Subject to subsection (c) below, if at any time the Company shall
receive a written request from the Holders of at least 66.67% of the Registrable
Securities requesting that the Company effect the registration of all of the
Registerable Securities held by such Holders under the Securities Act, the
Company shall use its best efforts to effect such registration as soon as
practicable. The Company shall not be required to effect any registration
pursuant to this Section 2(a) unless such registration can be made on Form S-3
or any similar short-form registration. The

 
                                       2

<PAGE>   14



registration requested pursuant to this Section 2(a) is referred to herein as
the "Demand Registration". The request for the Demand Registration shall specify
the approximate number of Registrable Securities requested to be registered and
the anticipated per share price range for such offering. Within twenty (20) days
after receipt of the request, the Company will give written notice of such
requested registration to all other Holders of Registrable Securities, if any,
and, subject to Section 2(b) below, will include in the Demand Registration all
Registrable Securities with respect to which the Company has received written
requests for inclusion therein within 20 days after the giving of the Company's
notice.

         (b) Priority on Demand Registration. Subject to the provisions of
Paragraph 5, the Company may include in the Demand Registration other securities
which the Company has been requested or otherwise desires to register on behalf
of itself or others, but which are not Registrable Securities; provided,
however, that no securities other than the Registrable Securities shall be
included in such Demand Registration if the Demand Registration is an
underwritten registration and the managing underwriter advises the Company that
the inclusion of securities other than the Registerable Securities would
adversely affect such Demand Registration unless a majority of the Holders who
had requested the Demand Registration shall have consented in writing to the
inclusion of such other securities.

         (c) Restrictions on Demand Registration. The Company shall not be
obligated to effect the Demand Registration within 120 days after the effective
date of a previous registration by the Company of any shares of its Common
Stock, other than shares registered pursuant to Form S-8 or Form S-4 in which
the Holders of Registrable Securities were given rights pursuant to Section 3.

         (d) Selection of Underwriters. The Holders of a majority of the
Registrable Securities included in the Demand Registration shall have the right
to select the investment banker(s) and manager(s) to administer the offering,
subject to the Company's approval which shall not be unreasonably withheld.

3. Company Registration.

         If at any time or from time to time, the Company shall determine to
register any of its equity securities, either for its own account or the account
of a security holder or holder (including, without limitation pursuant to any
public offering or a demand for registration of any shareholder of the Company)
under the Securities Act other than on Form S-8 or Form S-4, the Company will:
(a) promptly give to the Holder written notice thereof (which shall include a
list of the jurisdictions in which the Company intends to attempt to qualify
such securities under the applicable blue sky or other state securities laws);
and (b) include in such registration (and any related qualification under blue
sky laws or other compliance) and in any underwriting involved therein, all the
Registrable Securities specified in a written request made within thirty days
after receipt of such written notice from the Company by the Holder; except that
if, in connection with any offering involving an underwriting of Common Stock to
be issued by the Company, the managing underwriter shall impose a limitation on
the number of shares of Common Stock which may be included in the Registration
Statement because, in its judgment, such limitation is necessary to effect an
orderly public distribution, then the Company shall be obligated to include in
such Registration Statement

                                       3
<PAGE>   15



only such limited portion (or none, if so required by the managing underwriter)
of the Registrable Securities with respect to which such Holder has requested
inclusion hereunder.

4. Effectiveness.

         A Registration Statement pursuant to which any Registrable Securities
are being offered will not be deemed to have become effective unless it has been
declared effective by the SEC; provided, however, that if, after it has been
declared effective, the offering of the Registrable Securities pursuant to such
registration statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
registration statement will be deemed not to have been effective during the
period of such interference, until the offering of Registrable Securities
pursuant to such registration statement may legally resume. The Company will be
deemed not to have used best efforts to cause the registration statement to
become, or to remain, effective during the requisite period if it voluntarily
takes any action that would result in any such registration statement not being
declared effective or that would result in the Holder not being able to offer
and sell the Registrable Securities during that period unless such action is
required by applicable laws and regulations or currently prevailing
interpretations of the staff of the SEC. The Company shall use best efforts to
maintain the effectiveness for up to one hundred twenty (120) days (or such
shorter period of time as the underwriters need to complete the distribution of
the registered offering) of any Registration Statement pursuant to which any of
the Registrable Securities are being offered, and from time to time will amend
or supplement such Registration Statement and the Prospectus contained therein
to the extent necessary to comply with the Securities Act and any applicable
state securities laws or regulations. The Company shall also provide the Holder
with as many copies of the Prospectus contained in any such Registration
Statement as the Holder may reasonably request.

5. Expenses of Registration.

         All Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to this Agreement shall be borne by the
Company. Except as provided herein, the Holder shall pay all fees and expenses
of its legal counsel, underwriters' fees, discounts or com missions or transfer
taxes, if any, relating to the sale or disposition of the Holder's Registrable
Securities.

6. Registration Procedures.

         In the case of each registration, qualification, or compliance effected
by the Company pursuant to this Agreement, the Company will keep the Holder
advised in writing as to the initiation of each registration, qualification and
compliance and as to the completion thereof. At its expense, the Company will:

(a) Prepare and file with the SEC a Registration Statement with respect to such
Registrable Securities as described in Sections 2 or Section 3 and use its best
efforts to cause such Registration Statement to become effective and to remain
effective in accordance with Section 4 (provided that before filing a
Registration Statement or Prospectus or any amendments or supplements thereto,
the

                                        4
<PAGE>   16



Company will furnish to the counsel selected by the Holder copies of all such
documents proposed to be filed, which documents will be subject to the review of
such counsel);

(b) Prepare and file with the SEC such amendments and supplements to such
Registration Statement and the Prospectus used in connection therewith as may be
necessary to keep such Registration Statement effective and current for a period
of not less than one hundred twenty (120) days and comply with the provisions of
the Securities Act with respect to the disposition of all securities covered by
such Registration Statement during such period in accordance with the intended
methods of disposition by the sellers thereof as set forth in such Registration
Statement;

(c) (i) Furnish to the Holder, and to each underwriter, if any, without charge,
such number of copies of such Registration Statement, each amendment and
supplement thereto, the Prospectus included in such Registration Statement
(including each preliminary Prospectus), and such other documents as the Holder
or underwriters may reasonably request in order to facilitate the disposition of
the Registrable Securities owned by the Holder; and (ii) consent to the use of
the Prospectus or any amendment or supplement thereto by the Holder of
Registrable Securities included in the Registration Statement in connection with
the offering and sale of the Registrable Securities covered by the Prospectus or
any amendment or supplement thereto;

(d) Use its best efforts to register or qualify such Registrable Securities
under all applicable securities or blue sky laws of such jurisdictions of the
United States by the time the applicable Registration Statement is declared
effective by the SEC as the Holder and any underwriters reason ably request in
writing and do any other related acts which may be reasonably necessary or
advisable to enable the Holder and underwriters to consummate the disposition in
such jurisdictions of the Registrable Securities owned by the Investor;
provided, however, that the Company shall not be required to (i) qualify as a
foreign corporation or as a dealer in securities in any jurisdiction where it
would not otherwise be required to qualify but for this Section 6(d), (ii) file
any general consent to service of process in any jurisdiction where it would not
otherwise be subject to such service of process or (iii) subject itself to
taxation in any such jurisdiction if it is not then so subject;

(e) Notify the Holder, its counsel, and the managing underwriters, if any,
promptly, and promptly confirm such notice in writing, (i) at any time when a
Prospectus relating thereto is required to be delivered under the Securities
Act, of the happening of any event as a result of which, or the fact that, the
Prospectus included in such Registration Statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of the Investor, the Company will prepare a
supplement or amendment to such Prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such Prospectus will not contain
any untrue statement of a material fact or omit to state any fact necessary to
make the statements therein not misleading; (ii) when a Registration Statement
has become effective and when any post-effective amendments and supplements
thereto become effective, (iii) of any request by the SEC or any state
securities authority for amendments and supplements to a Registration Statement
or Prospectus or for additional information after the Registration Statement has
become effective, (iv) of the issuance by the SEC or any state securities
authority of any stop order suspending the effectiveness of a Registration
Statement or the qualification of the Registrable Securities or the initiation
of any proceedings for that purpose, (v) if, between the effective date of

                                       5
<PAGE>   17



a Registration Statement and the closing of any sale of Registrable Securities
covered thereby, the representations and warranties of the Company contained in
any purchase agreement, securities sales agreement or other similar agreement,
if any, cease to be true and correct in all material respects, and (vi) the
Company's reasonable determination that a post-effective amendment to the
Registration Statement would be appropriate;

(f) If applicable, use its best efforts to cause all such Registrable Securities
to be listed or quoted on each securities exchange or interdealer quotation
system on which similar securities issued by the Company are then listed or
quoted;

(g) Provide a transfer agent for all such Registrable Securities not later than
the effective date of such Registration Statement;

(h) Enter into such customary agreements (including underwriting agreements on
customary terms) and take all such other actions as the Investor or the
underwriters, if any, reasonably requests in order to expedite or facilitate the
disposition of such Registrable Securities;

(i) Obtain for delivery to the Company and the managing underwriters, if any,
with copies to the Holder of the Registrable Securities being registered, a
comfort letter from the Company's independent public accountants in customary
form and covering such matters of the type customarily covered by comfort
letters as the Holder shall reasonably request, dated the effective date of the
Registration Statement and brought down to the closing;

(j) If necessary, obtain a CUSIP number for the Registrable Securities not later
than the effective date of the Registration Statement; and

(k) Make available for inspection by the Holder, any underwriter participating
in any disposition pursuant to such Registration Statement and any attorney,
accountant or any other agent retained by the Investor or any such underwriter,
all financial and other records, pertinent corporate documents and properties of
the Company, and cause the Company's officers, directors and employees to supply
all information reasonably requested by the Holder, any such underwriter,
attorney, accountant or agent in connection with such Registration Statement.

(l) Cooperate with the Holder to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold and not bearing
any restrictive legends and registered in such names as the Holder or the
underwriters may reasonably request at least two Business Days prior to the
closing of any sale of Registrable Securities pursuant to such Registration
Statement;

(m) Cooperate with the Holder to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold and not bearing
any restrictive legends and registered in such names as the Holder or the
underwriters may reasonably request at least two Business Days prior to the
closing of any sale of Registrable Securities pursuant to such Registration
Statement;

(n) upon the occurrence of any circumstance contemplated by Section 6(e)(iii),
6(e)(iv), or 6(e)(v) hereof, use best efforts to prepare a supplement or
post-effective amendment to such

                                        6
<PAGE>   18



Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities, such Prospectus will
not contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; and to notify the Holder to suspend
use of the Prospectus as promptly as practicable after the occurrence of such an
event, and the Holder hereby agrees to suspend use of the Prospectus until the
Company has amended or supplemented the Prospectus to correct such misstatement
or omission;

(n) cooperate with each seller of Registrable Securities covered by any
Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Securities and their respective counsel in
connection with any filings required to be made with the NASD; and

(o) use best efforts to take all other steps necessary to effect the
registration of the Registrable Securities covered by a Registration Statement
contemplated hereby.

7. Indemnification and Contribution.

         (a) In connection with any Registration Statement, the Company shall
indemnify and hold harmless the Holder and each underwriter who participates in
an offering of the Registrable Securities, each Person, if any, who controls any
of such parties within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act and each of their respective directors, officers,
employees and agents, as follows:

                  (i) from and against any and all loss, liability, claim,

         covering Registrable Securities, including all documents incorporated
         therein by reference, or the omission or alleged omission therefrom of

         investigation or proceeding by any court or governmental agency or
         body, commenced or threatened, or any claim whatsoever based upon any
         such untrue statement or omission, or any such alleged untrue statement
         or omission, to the extent that any such expense is not paid under
         subparagraph (i) or (ii) of this Section 7(a);

provided, however, that (i) this indemnity does not apply to any loss,
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished in writing to the
Company by the Holder, or any underwriter with respect to the Holder, or any
underwriter, as the case may be, expressly for use in a Registration Statement
(or any amendment thereto) or any Prospectus (or any amendment or supplement
thereto) and (ii) the Company shall not be liable to the Holder, any underwriter
or controlling Person, with respect to any untrue statement or alleged untrue
statement or omission or alleged omission in any preliminary Prospectus to the
extent that any such loss, liability, claim, damage or expense of the Holder,
any underwriter or controlling Person results from the fact that the Holder or
any underwriter, sold Shares to a Person to whom there was not sent or given, at
or prior to the written confirmation of such sale, a copy of the final
Prospectus as then amended or supplemented if the Company had previously
furnished copies thereof to the Holder or any underwriter or controlling Person
and the loss, liability, claim, damage or expense of the Holder or underwriter,
or controlling Person results from an untrue statement or omission of a material
fact contained in the preliminary Prospectus which was corrected in the final
Prospectus. Any amounts advanced by the Company to an indemnified party pursuant
to this Section 6 as a result of such losses shall be returned to the Company if
it shall be finally determined by such a court in a judgment not subject to
appeal or final review that such indemnified party was not entitled to
indemnification by the Company.

         (b) The Holder agrees to indemnify and hold harmless the Company, any
underwriter and each of their respective directors, officers (including each
officer of the Company who signed the Registration Statement), employees and
agents, any underwriter or any other selling Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
against any and all loss, liability, claim, damage and expense whatsoever
described in the indemnity contained in Section 7(a) hereof, as incurred, but
only with respect to untrue statements or omissions, or alleged untrue
statements or omissions, made in a Registration Statement or any Prospectus in
reliance upon and in conformity with written information furnished to the
Company by such selling Holder with respect to such Holder expressly for use in
such Registration Statement, or any such Prospectus;

         (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party, but failure to so notify an indemnifying party
shall not relieve such indemnifying party from any liability which it may have
under this Section 7, except to the extent that it is materially prejudiced by
such failure. An indemnifying party may participate at its own expense in the
defense of such action, or, if it so elects within a reasonable time after
receipt of such notice, assume the defense of any suit brought to enforce any
such claim; but if it so elects to assume the defense, such defense shall be
conducted by

                                       8
<PAGE>   20



counsel chosen by it and approved by the indemnified party or parties, which
approval shall not be unreasonably withheld. In the event that an indemnifying
party elects to assume the defense of any such suit and retain such counsel, the
indemnified party or parties shall bear the fees and expenses of any additional
counsel thereafter retained by such indemnified party or parties; provided,
however, that the indemnified party or parties shall have the right to employ
counsel (in addition to local counsel) to represent the indemnified party or
parties who may be subject to liability arising out of any action in respect of
which indemnity may be sought against the indemnifying party if, in the
reasonable judgment of counsel for the indemnified party or parties, there may
be legal defenses available to such indemnified party or parties which are
different from or in addition to those available to the indemnifying party, in
which event the fees and expenses of appropriate separate counsel shall be borne
by the indemnifying party. In no event shall the indemnifying parties be liable
for the fees and expenses of more than one counsel (in addition to local
counsel), separate from its own counsel, for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 7 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release in form and substance satisfactory to the
indemnified parties of each indemnified party from ail liability arising out of
such litigation, investigation, proceeding or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

         (d) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 7 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company and the Holder
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by such indemnity agreement incurred by the
Company and the Holder, as incurred; provided that no Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person that was not
guilty of such fraudulent misrepresentation. As between the Company and the
Holder, such parties shall contribute to such aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by such indemnity
agreement in such proportion as shall be appropriate to reflect the relative
fault of the Company, on the one hand, and the Holder, on the other hand, with
respect to the statements or omissions which resulted in such loss, liability,
claim, damage or expense, or action in respect thereof, as well as any other
relevant equitable considerations. The relative fault of the Company, on the one
hand, and of the Holder, on the other hand, shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company, on the one hand, or by or on behalf of the
Holder, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Holder agree that it would not be just and equitable if
contribution pursuant to this Section 7 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the relevant equitable considerations. For purposes of this

                                        9

Section 7, each affiliate of the Holder, and each director, officer, employee,
agent and Person, if any, who controls a Holder or such affiliate within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
shall have the same rights to contribution as the Holder, and each director of
the Company, each officer of the Company who signed the Registration Statement,
and each Person, if any, who controls the Company within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as the Company.

8. Information by Holder.

         The Holder or Holders of Registrable Securities included in any
registration shall furnish to the Company such written information regarding
such Holder or Holders and the distribution proposed by such Holder or Holders
as the Company may reasonably request in writing and as shall be required in
connection with any registration, qualification, or compliance referred to in
this paragraph.

9. Transfer of Registration Rights.

         The rights to cause the Company to register the Registrable Securities
granted to the Holder by the Company under Section 2 or Section 3 may be
assigned by a Holder to a transferee or assignee of any of such Holder's
Registrable Securities, provided, that the Company is given written notice by
such Holder at the time of, or within a reasonable time after, said transfer,
stating the name and address of said transferee or assignee and identifying the
securities with respect to which such registration rights are being assigned.

10. No Inconsistent Agreements.

         The Company has not entered into nor will the Company on or after the
date of this Agreement enter into any agreement which is inconsistent with the
rights granted to the Investor with respect to the Shares in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Investor hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's other issued and outstanding
securities under any such agreements.

11. Assignability.

         This Agreement shall be binding upon and inure to the benefit of the
respective heirs, successors and assigns of the parties hereto.

12. Changes in Capital Stock.

         If, and as often as, there is any change in the Common Stock by way of
a stock split, stock dividend, combination or reclassification, or through a
merger, consolidation, reorganization or recapitalization, or by any other
means, appropriate adjustment shall be made in the provisions hereof so that the
rights and privileges granted hereby shall continue with respect to the Shares
as so changed.

13. Governing Law.

         This Agreement shall be governed by and construed in accordance with
the laws of Illinois, without regard to the conflict of laws provisions thereof.

         Any modification, amendment or waiver of this Agreement or any
provision hereof shall be in writing and executed by Holders of not less than
66-2/3 percent of the Registrable Securities; provided, however, that no such
modification, amendment or waiver shall reduce the aforesaid percentage of
Registrable Securities without the consent of the record or beneficial holders
of no less than 90 percent of the Registrable Securities.

15. Severability.

         In the event that any one or more of the provisions contained herein,
or the application thereof in any circumstance, is held invalid, illegal or
unenforceable, the validity, legality and enforceability of any such provision
in every other respect and of the remaining provisions contained herein shall
not be affected or impaired thereby.

16. Successors and Assigns.

         This Agreement shall inure to the benefit of and be binding upon the
successors, assigns and transferees of the Holder, including, without limitation
and without the need for an express assignment, subsequent Holders. If any
transferee of the Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities, such Person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement and such Person shall be entitled to receive the benefits hereof.

17. Entire Agreement.

         This Agreement and the other writings referred to herein contain the
entire understandings among the parties with respect to its subject matter. This
Agreement supersedes all prior agreements and understandings among the parties
with respect to its subject matter.

18. Headings.

         The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning hereof.

19. Counterparts.

which shall be an original, but all of which together shall constitute one
instrument.
