                         NOTES TO FINANCIAL STATEMENTS
                               December 31, 1998
                                  (Unaudited)

       Pharmaceutical Resources, Inc. (the "Company" or "PRI") operates in one
business segment, the manufacture and distribution of generic pharmaceuticals in
the United States. Marketed products are principally in solid oral dosage form
(tablet, caplet and two-piece hard-shell capsule). The Company also distributes
products in the semi-solid form of a cream, reconstituted suspensions/solutions
and transdermal delivery systems.

Basis of Preparation:

       The accompanying financial statements at December 31, 1998 and for the
three-month periods ended December 31, 1998 and December 27, 1997 are unaudited;
however, in the opinion of management of PRI, such statements include all
adjustments (consisting of normal recurring accruals) necessary to a fair
statement of the information presented therein. The balance sheet at September
30, 1998 was derived from the audited financial statements at such date.

       Pursuant to accounting requirements of the Securities and Exchange
Commission applicable to quarterly reports on Form 10-Q, the accompanying
financial statements and these notes do not include all disclosures required by
generally accepted accounting principles for audited financial statements.
Accordingly, these statements should be read in conjunction with PRI's most
recent annual financial statements.

       Results of operations for interim periods are not necessarily indicative
of those to be achieved for full fiscal years. Certain items on the consolidated
financial statements for the prior years have been reclassified to conform to
the current year financial statement presentation.

       In December 1998, the Company changed its annual reporting period to a
fiscal year ending December 31 from a fiscal year ending September 30.
Accordingly, the next fiscal year will commence on January 1, 1999 and will end
on December 31, 1999, and the fiscal quarters will end on April 3, 1999, July 3,
1999, October 2, 1999 and December 31, 1999. The results of operations for the
transition period from October 1, 1998 to December 31, 1998 are included in this
filing of Form 10-Q.

Strategic Alliance:

       On June 30, 1998, the Company completed a strategic alliance with Merck
KGaA, a pharmaceutical, laboratory and chemical company located in Darmstadt,
Germany ("Merck KGaA"). Pursuant to a Stock Purchase Agreement, dated March 25,
1998, Merck KGaA, through its subsidiary Lipha Americas, Inc. ("Lipha"),
purchased 10,400,000 newly issued shares of the Company's Common Stock for
$20,800,000. In addition, the Company issued to Merck KGaA and Genpharm, Inc.
("Genpharm"), a Canadian subsidiary of Merck KGaA, five-year options to purchase
an aggregate of 1,171,040 shares of the Company's Common Stock at an exercise
price of $2.00 per share in exchange for consulting services. The options expire
in April 2003 and become exercisable commencing in July 2001. As part of the
alliance, the Company received the exclusive United States distribution rights
to the portfolio of products covered by a distribution agreement with Genpharm
(see "--Distribution Agreements-Genpharm, Inc."). Merck KGaA also purchased
1,813,272 shares of the Company's Common Stock from Clal Pharmaceutical
Industries Ltd. ("Clal"), PRI's largest shareholder prior to the transaction.
Clal has the right to cause Merck KGaA and/or the Company to purchase an
additional 500,000 shares of Common Stock from Clal at a price of $2.50 per
share in July 2001.

Development Agreement:

       The Company, Israel Pharmaceutical Resources L.P. ("IPR") and Generics
(UK) Ltd. ("Generics"), a subsidiary of Merck KGaA, have a development agreement
(the "Development Agreement"), dated August 11, 1998, in which Generics will
fund one-half the costs of the operating budget of IPR, the Company's research
and development operation in Israel, in exchange for the exclusive distribution
rights outside of the United States to products developed by IPR after the date
of the Development Agreement. The Development Agreement has an initial term of
five years and shall automatically renew for additional periods of one year or
earlier termination upon six months notice in certain circumstances. Pursuant to
the Development Agreement, Generics paid the Company an initial fee of $600,000
in August 1998 and fulfilled the funding requirements for the three-month period
ended December 31, 1998. Under the agreement, Generics is not required to fund
more than $1,000,000 in any one calendar year.

                                  (Unaudited)

Distribution Agreements:

  Genpharm, Inc.

       The Company has a distribution agreement with Genpharm (the "Genpharm
Distribution Agreement") pursuant to which Genpharm granted exclusive
distribution rights to the Company within the United States and certain other
United States territories with respect to approximately 40 generic
pharmaceutical products currently being developed or identified for development,
some of which have obtained U.S. Food and Drug Administration ("FDA") approval
and others of which have been or will be submitted to the FDA for approval.
Products may be added to or removed from the Genpharm Distribution Agreement by
mutual agreement of the parties. Genpharm is required to use commercially
reasonable efforts to develop the products, which are subject to the Genpharm
Distribution Agreement, and is responsible for the completion of product
development and for obtaining all applicable regulatory approvals. The Company
will pay Genpharm a percentage of the gross profits attributable to the sales of
such products by the Company.

  BASF Corporation

       In April 1997, Par Pharmaceutical, Inc. ("Par"), the Company's operating
subsidiary, entered into a Manufacturing and Supply Agreement (the "Supply
Agreement") with BASF Corporation ("BASF"), a manufacturer of pharmaceutical
products. Under the Supply Agreement, Par agreed to purchase certain minimum
quantities of certain products manufactured by BASF at one of its facilities,
and phase out Par's manufacturing of those products. BASF agreed to discontinue
its direct sale of those products. The agreement has an initial term of three
years (subject to earlier termination upon the occurrence of certain events as
provided therein) and thereafter renews automatically for successive two-year
periods to December 31, 2005, if Par has met certain purchase thresholds. In
each of the first three years of the initial term of the Supply Agreement, Par
agreed to purchase at least $24,500,000 worth of three products. Further, if Par
does not purchase at least $29,000,000 worth of one of those products in the
third and final year of the agreement, BASF has the right to terminate the
agreement with a notice period of one year. The Company has met the minimum
purchase requirements of calendar year 1998 for two of the higher volume
products and BASF has waived the minimum purchase requirements in calendar year
1998 for the third product.

  Elan Corporation

       On September 29, 1998, the Company and Elan Transdermal Technologies,
Inc., formerly known as Sano Corporation, and Elan Corporation, plc
(collectively "Elan") entered into a termination agreement (the "Termination
Agreement") with respect to their prior distribution agreement. Pursuant to the
Termination Agreement Par has the exclusive right to distribute in the United
States a transdermal nicotine patch manufactured by Elan for a twelve-month
period ending September 29, 1999 or earlier termination upon three months notice
in certain circumstances. In January 1999, Elan notified the Company that its
distribution rights with respect to the nicotine patch will be terminated
effective April 30, 1999. Par must pay Elan a certain percentage of gross
profits from the sale of the nicotine patch through the termination date. In
exchange for relinquishing long-term distribution rights for the nicotine patch
and a nitroglycerin patch, PRI received a cash payment of $2,000,000 in October
1998 and will receive an additional payment of $2,000,000, upon the termination
of the Company's distribution rights, less any gross profit generated by sales
of the product subject to a minimum payment of $1,000,000. Pursuant to the
Termination Agreement, Elan agreed to pay Par a perpetual royalty for all non-
prescription sales of the transdermal nicotine patch by Elan in the United
States and Israel.
The Company began selling Elan's nicotine patch in January 1998.

Short-Term Debt:

       In December 1996, Par entered into a Loan and Security Agreement (the
"Loan Agreement") with General Electric Capital Corporation ("GECC") which
provided Par with a three-year revolving line of credit. Pursuant to the Loan
Agreement, as amended, Par is permitted to borrow up to the lesser of (i) the
borrowing base established under the Loan Agreement or (ii) $20,000,000. The
borrowing base is limited to 85% of eligible accounts receivable plus 50% of
eligible inventory of Par, each as determined from time to time by GECC. The
interest rate charge on the line of credit is based upon a per annum rate of 
2 1/4% above the 30-day commercial paper rate for high-grade unsecured notes
adjusted monthly. The line of credit with GECC is secured by the assets of Par
and PRI other than real property and

is guaranteed by PRI. In connection with such facility, GECC can require the
Company and its affiliates to establish a cash management system pursuant to
which all cash and cash equivalents received by any of such entities are
deposited into a lockbox account over which GECC has sole operating control. On
June 30, 1998, the Company paid all remaining outstanding revolving credit
advances pursuant to the Loan Agreement with GECC with a portion of the proceeds
from an equity investment and GECC relinquished operating control over the
Company's cash receipts. As of February 12, 1999, the borrowing base was
approximately $13,441,000 and no amounts were outstanding under the line of
credit. The revolving credit facility is subject to covenants based on various
financial benchmarks.

Income Taxes:

       Based on the Company's recent performance and uncertainty of the generic
business in which it operates, management believes that future operating income
might not be sufficient to recognize fully the net operating loss carryforwards
of the Company. Therefore, the Company did not recognize a benefit for its
operating losses in either of the three-month periods ended December 31, 1998 or
December 27, 1997. If the Company is unable to generate sufficient taxable
income in the future, the Company expects that increases in the valuation
allowance will be required through a charge to expense.

Earnings Per Share:

       In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS
128"), which is effective for financial statements for periods ending after
December 15, 1997, and requires replacement of primary and fully diluted
earnings per share with basic and diluted earnings per share including
retroactive restatement of all prior earnings per share data. Under SFAS 128,
the dilutive effect of stock options is excluded from the calculation of basic
earnings per share but included in diluted earnings per share. The Company
adopted the accounting standard during the quarter ended December 27, 1997 and,
accordingly, has presented all earnings per share data to conform to the
requirements of SFAS 128.

       Outstanding options and warrants of 514,700 as of December 31, 1998 and
1,996,250 as of December 27, 1997 were not included in the computation of
diluted earnings per share because the exercise prices were greater than the
average market price of the Common Stock in the respective periods. In addition,
incremental shares from assumed conversions of 756,290 as of December 31, 1998
were excluded from diluted earnings per share because they were nondilutive.

Comprehensive Income:

       During the three months ended December 31, 1998, the Company adopted
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive 
Income" ("SFAS 130"), which establishes standards for the reporting and 
display of comprehensive income and its components. There was no impact on the
financial statements as a result of the adoption of SFAS 130.

Commitments, Contingencies and Other Matters:

  Retirement Plans:

       The Company has a defined contribution, social security integrated
Retirement Plan (the "Retirement Plan") providing retirement benefits to
eligible employees as defined in the Retirement Plan. The Company suspended
employer contributions to the Retirement Plan effective December 30, 1996.
Consequently, participants in the Retirement Plan will no longer be entitled to
any employer contributions under such plan for 1996 or subsequent years. The
Company also maintains a Retirement Savings Plan (the "Retirement Savings Plan")
whereby eligible employees are permitted to contribute from 1% to 12% of pay to
the Retirement Savings Plan. The Company contributes an amount equal to 50% of
the first 6% of the pay contributed by the employee. In fiscal year 1998, the
Company merged the Retirement Plan into the Retirement Savings Plan.

  Legal Proceedings:

       The Company is involved in certain litigation matters, including certain
product liability actions and actions by a former officer for, among other
things, breach of contract. Such actions seek damages from the Company,
including compensatory and punitive damages. The Company intends to defend these
actions vigorously. The Company believes that these actions are incidental to
the conduct of its business and that the ultimate resolution thereof will not
have a material adverse effect on its financial condition or liquidity.

  Asset Impairment/Restructuring:

       In an attempt to reduce operating losses, the Company is implementing
measures during the three-month transition period ended December 31, 1998 and
during 1999 to reduce costs and increase operating efficiencies. The Company
will discontinue six unprofitable products from its product line, eliminate
approximately 70 positions, primarily in manufacturing and various manufacturing
support functions, and reduce certain related expenses. These measures resulted
in a charge of $1,906,000 in the transition period, which included provisions of
approximately $1,200,000 for write-downs related to the impairment of assets
affected by the termination of the six products, and $705,000 for severance
payments and other employee termination benefits. The Company began the work
force reduction with the layoff of approximately forty employees, primarily in
manufacturing functions and a smaller number in administrative positions, in
January 1999.

       Additionally, the Company recorded inventory reserves of $630,000
relating to the six discontinued products. This reserve is included as part of
cost of goods sold.

       The Company recorded a charge of $1,212,000 in fiscal year ended
September 30, 1998 for asset impairment of its Congers, New York facility as a
result of outsourcing the manufacture of most of the products from such
facility. The charge is based on the difference between the appraised value of
the property less the net book value at September 30, 1998. The Company is
currently planning to move the remaining manufacturing volume and coating
operation to another location and will attempt to sell or lease the facility in
fiscal year 1999.

                ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

       Certain statements in this Form 10-Q constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995, including those concerning management's expectations with respect to
future financial performance and future events, particularly relating to sales
of current products as well as the introduction of new manufactured and
distributed products. Such statements involve known and unknown risks,
uncertainties and contingencies, many of which are beyond the control of the
Company, which could cause actual results and outcomes to differ materially from
those expressed herein. Factors that might affect such forward-looking
statements set forth in this Form 10-Q include, among others, (i) increased
competition from new and existing competitors and pricing practices from such
competitors, (ii) pricing pressures resulting from the continued consolidation
by the Company's distribution channels, (iii) the amount of funds continuing to
be available for internal research and development and research and development
joint ventures, (iv) research and development project delays or delays in
obtaining regulatory approvals, (v) continuation of distribution rights under
significant agreements and (vi) the effectiveness of restructuring measures to
reduce losses and increase efficiencies.


RESULTS OF OPERATIONS

General

       The Company's operating loss was $6,972,000 for the three-month period
ended December 31, 1998 compared to $1,992,000 for the three-month period ended
December 27, 1997. Although the Company experienced 38% net sales growth from
sales of new distributed products, the gross margin for the period declined
significantly due to unfavorable manufacturing variances caused by excess
capacity and, to a lesser extent, additional inventory write-offs. In addition,
increased product development activity and higher selling and administrative
expenses, as described below, adversely impacted the operating loss for the
period. In an attempt to reduce operating losses, the Company is implementing
measures during the three-month transition period ended December 31, 1998 and
during 1999 in an attempt to reduce costs and increase operating efficiencies,
and accordingly, has recorded charges of $1,906,000 in the transition period for
restructuring and asset impairment, and inventory reserves of $630,000 following
a decision to discontinue six unprofitable products manufactured by the Company
(see "Notes to Financial Statements-Commitments, Contingencies and Other
Matters-Asset Impairment/Restructuring"). The Company expects to continue to
search for additional measures to improve its operations in order to reduce
costs and obtain other operating efficiencies. Further, the Company plans to
continue to seek new products through joint ventures, distribution and other
agreements with pharmaceutical companies located throughout the world. If
current sales and gross margin levels are not increased by sales of
substantially profitable new distributed or manufactured products, the Company
will continue to experience losses.

       In an effort to improve the Company's growth prospects through the
introduction of new products at profitable pricing and strengthen its financial
condition, PRI entered into a strategic alliance with Merck KGaA, which was
completed on June 30, 1998. As part of the alliance, the Company received the
sole rights to the portfolio of products covered by the Genpharm Distribution
Agreement, granting the Company exclusive United States distribution rights for
up to approximately 40 generic pharmaceutical products currently being developed
or identified for development, some of which have obtained FDA approval and
others of which have been or are expected to be submitted to the FDA for
approval. Genpharm pays the research and development costs associated with the
products and PRI will pay Genpharm a certain percentage of the gross margin on
sales of the products (see "Notes to Financial Statements-Strategic Alliance"
and "-Distribution Agreements-Genpharm, Inc."). This alliance provides the
Company with a significant number of potential products for its product
development pipeline without the substantial resource commitment, including
financial, it would normally take to develop such a pipeline, working capital
for possible business expansion, improved financial condition through
elimination of certain significant outstanding debt and access to Merck KGaA's
expertise and experience in the industry. To date, four products introduced
under the Genpharm Distribution Agreement did not have a significant impact on
the Company's operating results.

       The generic drug industry in the United States continues to be highly
competitive. The factors contributing to the intense competition and affecting
both the introduction of new products and the pricing and profit margins of the
Company, include, among other things; (i) introduction of other generic drug
manufacturer's products in direct competition with the Company's significant
products, (ii) consolidation among distribution outlets, (iii) increased ability


                                     --9--
<PAGE>
 
of generic competitors to enter the market after patent expiration, diminishing
the amount and duration of significant profits, (iv) willingness of generic drug
customers, including wholesale and retail customers, to switch among
pharmaceutical manufacturers, and (v) competition from brand name drug
manufacturers selling generic versions of their drugs.

       Critical to any significant improvement in the Company's financial
condition is the introduction and acquisition of new manufactured and
distributed products at selling prices that generate significant gross margin.
In addition to new product introductions expected as part of the strategic
alliance with Merck KGaA, the Company plans to continue to invest in research
and development efforts and pursue additional products for sale through new and
existing distribution agreements. The Company is engaged in efforts, subject to
FDA approval and other factors, to introduce new products as a result of its
research and development efforts and distribution and development agreements. No
assurance can be given that any additional products for sale by the Company will
occur or that sales of additional products will reduce losses or return the
Company to profitability. Continuing losses will adversely affect the Company's
liquidity and, accordingly, its ability to fund research and development or
ventures relating to the sale of new products (see "--Financial
Condition-Liquidity and Capital Resources").

Net Sales

       Net sales for the three months ended December 31, 1998 of $16,775,000
increased $4,641,000, or 38%, from sales of $12,134,000 for the corresponding
period of the prior fiscal year. The sales growth was primarily attributable to
sales of new products, primarily the transdermal nicotine patch manufactured by
Elan and Naproxen Sodium manufactured by the Company and introduced in October
1998. Net sales of distributed product for the most recent fiscal year increased
to approximately 68% of the Company's total net sales compared to approximately
31% of the total for the same period of the prior year continuing the trend of
greater reliance upon sales of distributed product. The Company is substantially
dependent upon distributed products for its sales and, as the Company introduces
new distributed products under its distribution agreements, it is expected that
this trend will continue. Pursuant to the Termination Agreement with Elan, the
Company will no longer have the transdermal nicotine patch to market after April
30, 1999. As a result of the continued evaluation of the existing product line,
the Company will discontinue six unprofitable products during fiscal year 1999
as existing inventory for those products is depleted. It is expected that the
termination of the transdermal nicotine patch distribution rights will adversely
affect the Company's annual net sales after April 1999. To a lesser extent, the
discontinued manufactured products will also negatively affect net sales.
However, it is anticipated that new product introductions in fiscal 1999 can
offset this expected net sales decrease.

       Levels of sales are principally dependent upon, among other things, (i)
pricing levels and competition, (ii) market penetration for the existing product
line, (iii) approval of abbreviated new drug applications ("ANDAs") and
introduction of new manufactured products, (iv) introduction of new distributed
products (v) the level of customer service, and (v) the continuation of existing
distribution agreements.

Gross Margin

       The Company's gross margin was $(330,000) (-2% of net sales) for the
three months ended December 31, 1998 compared to $1,504,000 (12% of net sales)
in the corresponding period of the prior fiscal year. Unfavorable manufacturing
variances due to excess capacity, caused by outsourcing or discontinuing
manufactured products in prior periods and higher inventory write-offs related
to discontinued products, adversely affected the gross margin in the current
period. The Company has attempted to address its excess capacity with the
restructuring implemented in the most recent quarter which resulted in layoffs
of manufacturing personnel in January 1999 and the write-down of certain assets
which will be under utilized as a result of discontinued products (see "Notes to
Financial Statements-Asset Impairment/Restructuring").

       Inventory write-offs amounted to $1,478,000 and $293,000 for the
three-month periods ended December 31, 1998 and December 27, 1997, respectively.
The increase in the current period was primarily attributable to the write-off
of material and work in process inventory not meeting the Company's quality
control standards and additional inventory reserves due to discontinued
products. The inventory write-offs, which have increased significantly over the
prior six months, are expected to return to a more normalized level in
subsequent periods. Inventory write-offs taken in the normal course of business
are related primarily to the disposal of finished products due to short shelf
life.

       The termination of the transdermal nicotine patch distribution rights,
discussed above, will negatively affect the Company's gross margin. However, it
is anticipated that the gross margins generated by sales of new product in
fiscal 1999 can offset this expected decrease.

Operating Expenses

  Research and Development

       Research and development expenses of $1,125,000 for the three-month
period ended December 31, 1998 increased $217,000 from the three-month period
ended December 27, 1997. The Company conducts a significant part of its research
and development in Israel through IPR. Following the acquisition of the
remaining interests of IPR in 1997, the Company's domestic research and
development program was integrated with that of IPR. The increased costs in the
current period were primarily due to biostudy activity by the domestic
operation. The current year costs for research and development expenses at IPR
were $374,000, net of $209,000 in funding from Generics, compared to $442,000 in
the prior year. Generics, a subsidiary of Merck KGaA, the Company and IPR have
an agreement pursuant to which Generics will share one-half of the costs of
IPR's operating budget, beginning in the three-month period ended December 31,
1998, in exchange for the exclusive distribution rights outside of the United
States to the products developed by IPR after the date of the agreement (see
"Notes to Financial Statements-Development Agreement").

       The Company has ANDAs for three potential products pending with the FDA
and awaiting approval. The Company expects to commence biostudies for eight
additional product submissions in fiscal year 1999. Recently, PRI has received
FDA approval of its ANDAs for three products, two of which the Company began
marketing in the quarter ended December 31, 1998, and the other is expected to
be introduced shortly.

       As part of the Genpharm Distribution Agreement, Genpharm pays the
research and development costs associated with the products covered by the
Genpharm Distribution Agreement. To date, the Company has introduced four
products under the Genpharm Distribution Agreement and anticipates introducing
several more in fiscal year 1999 (see "Notes to Financial
Statements-Distribution Agreements-Genpharm, Inc.").

  Selling, General and Administrative

       Selling, general and administrative costs for the three-month period
ended December 31, 1998 of $3,611,000 (22% of net sales) increased $1,023,000
from $2,588,000 (21% of net sales) for the corresponding period in the prior
fiscal year. The higher costs in the current period were primarily attributable
to strengthening the sales force and expanding marketing efforts, beginning in
the later half of the prior year, in anticipation of product introductions and
further market penetration of the existing product line, and to a lesser extent,
higher professional fees.

  Asset Impairment/Restructuring

       In an attempt to reduce operating losses, the Company is implementing
measures during the three month transition period ended December 31, 1998 and
during 1999 to reduce costs and increase operating efficiencies. The Company
will discontinue six unprofitable products from its product line, eliminate
approximately 70 positions, primarily in manufacturing and various manufacturing
support functions, and reduce certain related expenses. These measures resulted
in a charge of $1,906,000 in the transition period, which included provisions of
approximately $1,200,000 for write-downs related to the impairment of assets
affected by the termination of the six products, and $705,000 for severance
payments and other employee termination benefits. The Company began the work
force reduction with the layoff of approximately forty employees, primarily in
manufacturing functions and a smaller number in administrative positions, in
January 1999.

Income Taxes

       Management has determined, based on the Company's recent performance and
uncertainty of the generic business in which the Company operates, that future
operating income might not be sufficient to recognize fully the net operating
loss carryforwards of the Company. Therefore, the Company did not recognize a
benefit for its operating losses in either of the three-month periods ended
December 31, 1998 or December 27, 1997 (see "Notes to Financial
Statements-Income Taxes").

FINANCIAL CONDITION

Liquidity and Capital Resources

       Working capital of $24,208,000 at December 31, 1998 decreased $4,916,000
from $29,124,000 at September 30, 1998. The decrease is principally due to the
use of funds to finance operating losses and to build inventory on higher volume
products. The working capital ratio of 2.6x in the current period declined from
3.2x at fiscal 1998 year end.

       The Company, IPR and Generics have entered into an agreement, dated
August 11, 1998, pursuant to which Generics will fund one-half of the costs of
IPR's operating budget in exchange for the exclusive distribution rights outside
of the United States to the products developed by IPR after the date of the
agreement. The funding commenced in the three-month period ended December 31,
1998. Generics is not required to fund more than $1,000,000 in any one calendar
year (see "Notes to Financial Statements-Development Agreement").

       On September 29, 1998, the Company and Elan entered into the Termination
Agreement in which the Company would retain the exclusive distribution rights in
the United States to a transdermal nicotine patch for a period of up to twelve
months or earlier termination upon three months notice in certain circumstances.
In January 1999, Elan notified the Company that its distribution rights with
respect to the nicotine patch will be terminated effective April 30, 1999.
Pursuant to the Termination Agreement, PRI received a cash payment of $2,000,000
in October 1998 and will receive an additional $2,000,000 upon the termination
of the Company's distribution rights, less any gross profit generated by sales
of the product subject to a minimum payment of $1,000,000. In future periods, it
is anticipated that the Company will not receive any additional funds from the
sale of product rights to Elan (see "Notes to Financial Statements-Distribution
Agreements-Elan Corporation").

       The Company will attempt to sell or lease its manufacturing facility in
Congers, New York during fiscal year 1999 after moving a substantial portion of
its manufacturing volume to BASF. There can be no assurance that the Company
will be able to sell or lease the facility and, if sold, there can be no
assurance that the Company would receive its appraised value.

       The Company expects to fund its operations, including research and
development activities and its obligations under the existing distribution and
development arrangements discussed herein, out of its working capital and if
necessary with borrowings against its line of credit, to the extent then
available (see "Financing"). If, however, the Company continues to experience
significant losses over the next year, its liquidity and, accordingly, its
ability to fund research and development or ventures relating to the
distribution of new products would likely be materially and adversely affected.

Financing

       At December 31, 1998, the Company's total outstanding long-term debt,
including the current portion, amounted to $1,327,000. The amount consists
primarily of an outstanding mortgage loan with a bank and capital leases for
computer equipment.

       In December 1996, Par entered into the Loan Agreement with GECC which
provided Par with a three-year revolving line of credit. Pursuant to the Loan
Agreement, as amended, Par is permitted to borrow up to the lesser of (i) the
borrowing base established under the Loan Agreement or (ii) $20,000,000. The
borrowing base is limited to 85% of eligible accounts receivable plus 50% of
eligible inventory of Par, each as determined from time to time by GECC. The
interest rate charge on the line of credit is based upon a per annum rate of 
2 1/4% above the 30-day commercial paper rate for high-grade unsecured notes
adjusted monthly. The line of credit with GECC is secured by the assets of Par
and PRI other than real property and is guaranteed by PRI. In connection with
such facility, GECC can require the Company and its affiliates to establish a
cash management system pursuant to which all cash and cash equivalents received
by any of such entities are deposited into a lockbox account over which GECC has
sole operating control. On June 30, 1998, the Company paid all remaining
outstanding revolving credit advances pursuant to the Loan Agreement with a
portion of the proceeds from the equity investment by Merck KGaA. As of February
12, 1999, the borrowing base was approximately $13,441,000 and no amounts were
outstanding under the line of credit. The revolving credit facility is subject
to covenants based on various financial benchmarks.

Year 2000

       The Company has completed an assessment of its internal systems related
to Year 2000 compliance and is in the process of evaluating the status of its
customers, suppliers and banks. The Company has implemented a plan it believes
will enable its computerized information systems to be Year 2000 compliant
without any material disruption in business. The costs of addressing this issue
have been expended when incurred and have not, and the Company believes will not
in the future, have a materially adverse effect on its financial condition.
However, if third parties upon which the Company relies are unable to address
this issue in a timely manner, it could result in a material financial risk to
the Company. The Company anticipates devoting all resources necessary to resolve
any additional significant Year 2000 issues in a timely manner.

binding obligation of each Credit Party enforceable against each Credit Party in

          DEVELOPMENT AGREEMENT, dated as of August 11, 1998, among
                                             ---------

          WHEREAS, PRI and G(UK) and their respective Affiliates (as hereafter
defined) are engaged in manufacturing, marketing and distributing generic

          NOW, THEREFORE, the parties hereto agree as follows:

                                   ARTICLE 1

provided.  Defined terms shall be used in the singular or in the plural, as
sense shall require.

                                   ARTICLE 2
                         FUNDING AND PRODUCT SELECTION

          2.1  Initial Fee:  In consideration of the grant of rights by the
Partnership to G(UK) hereunder, G(UK) has paid previously to the Partnership or
its designee the sum of $600,000 US.  Such fee shall be non-refundable.

          2.2  Product Selection Committee:

          (a) A committee (the "Committee") shall be established to select
generic pharmaceutical  products to be developed by the Partnership and
manufactured and distributed by PRI and G(UK) and their Affiliates pursuant to
this agreement (the "Products"); provided, that, none of the Partnership
                                 --------  ----                         
Products shall be eligible for selection as a Product.  The Committee shall
initially consist of two directors.  The number of members of the Committee
shall not be changed without the written consent of PRI and G(UK).  PRI and
G(UK) each shall have the right to designate one Committee member.  In the event
of the death disability, resignation or other withdrawal of any Committee

                    adding generic pharmaceutical products;

                  Products.

          (c) Unless otherwise agreed by the Committee, the "Products" selected
shall be generic pharmaceutical products for which a US patent on the innovator
product or reference product is not due to expire for six years or more from the
date of selection.

          2.3  Funding Obligations:

          (a) Each year during the term of this agreement, each of PRI and G(UK)
shall pay to the Partnership an annual development fee equal to sum of the 50%
of the Budget approved by the Committee for the year, less the costs of active
and inactive raw materials and Bio-Availability Studies for the Products and the
Partnership Products and amortization and depreciation (the "Annual Fee").  It
is agreed that the Budget, less the costs of active and inactive raw materials
and Bio-Availability Studies for the Products and the Partnership Products and
amortization and depreciation, shall not exceed $2,000,000 US in any fiscal year
of the Partnership.  The Annual Fee shall be paid by each of PRI and G(UK) in
equal quarterly installments not later than on January 1, April 1, July 1 and
October 1 of each year.

          (b) The Annual Fee shall be paid in immediately available funds to an
account designated by the Partnership and shall be non-refundable.  The Annual
Fee obligations of PRI and G(UK) shall continue until the termination of this
Agreement.  The Annual Fee shall not be a loan unless PRI and G(UK) otherwise
agree in writing. No additional fees, other than the payment each year of the
Annual Fee and as set forth in Sections 2.1 and 2.3(c) and (d) hereof, will be
required to be made by PRI and G(UK) to the Partnership and any amounts paid in
any year in excess of the allocation of the Annual Fee will not reduce the
amount to be paid by such party in future years in respect of its Annual Fee.

          (c) PRI and G(UK) shall pay for or reimburse the Partnership for all
costs of all active and inactive raw materials used in connection with the
development of Products for the PRI Territory and G(UK) Territory, respectively.

          (d) PRI and G(UK) shall also be solely responsible for all out of
pocket costs and expenses relating to the registration, manufacture,
distribution, marketing and sale of Products (e.g., Bio-Availability Studies,
Product Approval expenses and lawsuits) in the PRI Territory and G(UK)
Territory, respectively.

                                   ARTICLE 3
                             EXCLUSIVE APPOINTMENT
                                        
          3.1  Exclusive Distributor: Subject to the provisions of this
agreement and to the receipt by PRI, G(UK) or their respective Affiliates, as
the case may be, of a Product Approval for such Product, the Partnership hereby
appoints (a) PRI as the sole and exclusive distributor of the Products for the
PRI Territory and PRI hereby accepts such appointment and agrees to act as such
sole distributor upon such terms and conditions and (b) G(UK) as the sole and
exclusive distributor of the Products for the G(UK) Territory and G(UK) hereby
accepts such appointment and agrees to act as such sole distributor upon such
terms and conditions.

          3.2  Nature of Relationship: This agreement does not constitute or
create (and the parties do not intend to create hereby) a joint venture, pooling
arrangement, partnership, or formal business organization of any kind between
and among any of the parties, and the rights and obligations of the parties
shall be only those expressly set forth herein. The relationship hereby
established between the Partnership, on the one hand, and PRI and G(UK), on the
other hand, is solely that of an independent contractor engaged in the operation
of its own respective business. None of the parties hereto shall be considered
to be an agent of any other (or any of its Affiliates) for any purpose
whatsoever.

          3.3  Territorial and Product Restrictions Applicable to PRI: During
the term of this agreement applicable to a Product, neither PRI nor any of its
Affiliates will directly or indirectly sell or license such Product outside of
the PRI Territory or to any Person in the PRI Territory where it knows or has
reason to believe that such Product will be resold by such Person outside of the
PRI Territory.  In the event the foregoing provision is or becomes unenforceable
or is unlawful in the PRI Territory, then it shall be deemed replaced by the
most restrictive provision on marketing or sale of the Product outside of the
PRI Territory as shall be lawful and enforceable in the PRI Territory. If G(UK)
establishes that one of PRI's customers or licensees or a customer or licensee
of any of its Affiliates is exporting such Product out of the PRI Territory, PRI
shall (and shall cause its Affiliates to) either cease to supply such customer
or obtain (and enforce, if necessary) an undertaking from such customer not to
sell the Product outside of the PRI Territory 


                                    --22--
<PAGE>
 
(unless PRI [or its Affiliate, as the case may be] is precluded from taking such
action under applicable law). Notwithstanding the foregoing, PRI shall not be in
violation of this Section 3.3 if G(UK) shall forfeit to PRI G(UK)'s exclusive
distribution and manufacturing rights pursuant to Section 5.1 below.

          3.4  Territorial and Product Restrictions Applicable to G(UK): During
the term of this agreement applicable to a Product, neither G(UK) nor any of its
Affiliates will directly or indirectly sell or license such Product outside of
the G(UK) Territory or to any Person in the G(UK) Territory where it knows or
has reason to believe that such Product will be resold by such Person outside of
the G(UK) Territory.  In the event the foregoing provision is or becomes
unenforceable or is unlawful in the G(UK) Territory, then it shall be deemed
replaced by the most restrictive provision on marketing or sale of the Product
outside of the G(UK) Territory as shall be lawful and enforceable in the G(UK)
Territory. If PRI establishes that one of G(UK)'s customers or licensees or a
customer or licensee of any of its Affiliates is exporting such Product out of
the G(UK) Territory, G(UK) shall (and shall cause its Affiliates to) either
cease to supply such customer or obtain (and enforce, if necessary) an
undertaking from such customer not to sell the Product outside of the G(UK)
Territory (unless G(UK) [or its Affiliate, as the case may be] is precluded from
taking such action under applicable law). In addition, G(UK) shall not (and it
shall not authorize, permit or suffer any of its Affiliates to), directly or
indirectly, manufacture, purchase, sell or distribute a Competing Product in the
G(UK) Territory at any time during the term of this agreement applicable to a
Product.

                                   ARTICLE 4
                      PRODUCT DEVELOPMENT AND REGISTRATION

          4.1  Obligations to Develop Products: Subject to the right of the
Committee to terminate the development of a Product, the Partnership shall use
commercially reasonable best efforts to develop the Products in accordance with
the requirements of applicable law in such order of priority as is determined by
the Committee. Nothing in this agreement shall constitute a guarantee or
warranty of the Partnership that development of any Product will be commenced or
continued or successfully completed within any specific time period or that a
Product Approval for any Product will be obtained.  All Products developed by
the Partnership and all applicable intellectual property rights shall be the
exclusive property of the Partnership and the Partnership shall be the exclusive
owner of all rights with respect to any Products developed by it, including,
without limitation, any manufacturing methods or intellectual property rights.
G(UK) and PRI agree and acknowledge that the Partnership has the right to
continue development of the Partnership Products concurrently with the
development of the Products; provided, that, the Committee will have the ability
                             --------  ----                                     
to determine the allocation of resources of the Partnership between the Products
and the Partnership Products. G(UK) shall have no rights with respect to the
Partnership Products.  THE PARTNERSHIP MAKES NO REPRESENTATION THAT ANY PRODUCT
WILL BE USEFUL FOR THE INTENDED PURPOSE OR THAT IT IS FREE FROM INHERENT SIDE
EFFECTS.

          4.2  Registration Responsibility: If a Product has been successfully
developed (as described below), it will be the sole responsibility of PRI or
G(UK) if PRI or G(UK), respectively, elects to distribute a product in the PRI
Territory or G(UK) Territory, respectively, (i) to file for Product Approvals in
the PRI Territory and G(UK) Territory, respectively, with the appropriate
authorities and (ii) where an application for Product Approval for such Product
has been submitted, to use commercially reasonable efforts to ensure that it
receives a Product Approval for such Product from the appropriate authorities on
the earliest possible schedule given the applicable process; provided, that, if
                                                             --------  ----    
G(UK) does not apply for Product Approval for a Product in any one or more
jurisdictions within the G(UK) Territory within 180 days of the successful
development of such Product or if G(UK) obtains a Product Approval with respect
to a Product and does not commercially market and sell any Products within 150
days of obtaining a Product Approval, PRI shall have all rights and obligations
of G(UK) as set forth in Articles 3, 4, 5, 7 and 8 hereof with respect to such
Product in the one or more jurisdictions within the G(UK) Territory in which
G(UK) failed to apply for Product Approvals or failed to commercially market and
sell the Product.  Product Approvals granted in respect of Products in a
jurisdiction within a territory will be registered in the name of the Party to
this agreement that has the right to distribute the Products within such
jurisdiction pursuant to Articles 3, 4 and 5 hereof.  For the purposes of this
agreement, a Product will deemed to be "successfully developed" if the Committee
determines in its sole and good faith judgment that the Product, in its current
state of development and without significant additional development or cost,
could obtain a Product Approval in one or more developed countries in the PRI
Territory or G(UK) Territory.  If the Committee cannot agree by a majority vote
of its members whether or not a Product has been "successfully developed," the
Committee shall hire an industry expert who has no business dealings with any of
the parties to this Agreement who will cast the deciding vote.  All expenses and
fees of such expert will be paid by the Partnership.  PRI and G(UK) shall be
responsible for and pay all expenses incurred by them in seeking Product
Approvals in their respective territories pursuant to Article 3 hereof and the
jurisdictions in which PRI and G(UK) shall have rights under Section 4.2 hereof
to distribute the Product.

                the development of a Product (and of which PRI and G(UK) have
                not been otherwise advised pursuant to (b) below); and

            (b) provide PRI and G(UK) with such information as PRI and G(UK) may

the Partnership to grant to PRI and/G(UK) a fully paid-up license upon the terms
herein contemplated to use the Product Information to obtain a Product Approval
for such Product in the PRI Territory and G(UK) Territory, respectively, such
right to be exercised by notice in writing to the Partnership.  Pursuant to such
license:

                conducted by PRI and/or G(UK) and their respective Affiliates at
                their sole cost and expense;

            (b) the Partnership will answer PRI's and G(UK)'s reasonable
                inquiries concerning such Product Information so as to enable
                PRI and G(UK) to obtain a Product Approval for the Product in
                question but it shall not be required to compile or develop
                information which is not already available to or possessed by
                it; and

            (c) Neither PRI nor G(UK) will use the Product Information licensed
                to it pursuant hereto to obtain a regulatory license or approval
                to market the Product outside of the PRI Territory or G(UK)
                Territory, respectively, except as permitted expressly in this
                Agreement.

          4.6  Waiver of Right of First Refusal: G(UK) shall cause Genpharm Inc.
to execute and deliver an agreement pursuant to which Genpharm Inc. waives all
of its rights under Section 3.10 of the Distribution Agreement, dated March 25,

its customer, or by their licensees to their customers.  For purposes of
computing Gross Sales and Net Sales, all sales and other transactions between
G(UK) and its Affiliates shall be disregarded and sales and other transactions
between G(UK) and its Affiliates shall not constitute a license by G(UK) or its
Affiliates, but shall be deemed to be a sale generating Gross Sales and Net
Sales.

and shall cause its Affiliates to provide to the Partnership, promptly following
a request therefor, such additional information concerning any sales of a

plus 3%, compounded daily.

          6.5  Maintenance of Records:  Each of the parties hereto agrees that
it shall keep (and shall cause its Affiliates to keep) complete and accurate
books and records of account containing all information required for the
computation and verification of all amounts on which payments hereunder are
based and shall, upon reasonable written notice from the other, make such
records available for examination by such other party or, at the requesting
party's expense, supply copies of such records to such other party.

          8.1  Limitation re Claims: Subject to the limitations set forth in
this Section 8.1, PRI, G(UK) and the Partnership covenant and agree to
indemnify, save harmless and compensate the other (and its Affiliates, for whose

or omission constituting gross negligence, the claim of the aggrieved party for
Damages arising out of the breach shall be limited to claiming the amounts owing
or payable to it in accordance with the provisions of this agreement and any out
of pocket costs and expenses (including amounts paid or payable by it to third
parties) which it has incurred and the aggrieved party shall not be entitled to
recover from the defaulting or breaching party any lost profits or consequential
or punitive damages, including loss or damage to its goodwill or reputation.

sale, marketing or other release in the PRI Territory by PRI or its Affiliates,
or in the G(UK) Territory by G(UK) or its Affiliates or their licensees, or the
research, development or application for Product Approval, of any Product
results in a third-party claim or results in any challenge under applicable
legislation or regulation:

          (a) to the extent that the Damages awarded or incurred relate to or
              arise out of any act by or omission of G(UK) or any of its
              Affiliates or any other Persons for whose acts or omissions they
              are responsible at law, G(UK) shall be responsible therefor and

              and the Partnership from and against all such Damages;

          (b) to the extent that the Damages awarded or incurred relate to or
              arise out of any or omission of PRI or any of its Affiliates or

              more of them is responsible at law, PRI shall be responsible
              therefor and shall defend, indemnify and hold harmless G(UK) and
              its Affiliates from and against all such Damages;

          (c) to the extent that the Damages awarded or incurred relate to or
              arise out of an actual or threatened claim, demand, action, cause
              of action, suit or proceeding that any Product researched or
              developed by the Partnership or application for Product Approval
              or proposed marketing or sale of a Product infringes any patent or
              other proprietary right of another Person or violates any
              applicable law or regulation, the Party to this agreement which
              shall have the right to distribute the Product in the jurisdiction
              within the PRI Territory or G(UK) Territory in which the lawsuit
              shall be filed or other legal or non-legal charge asserted shall
              be responsible therefor and shall defend, indemnify and hold
              harmless the Partnership and the other Party to this agreement and
              their Affiliates from and against any and all Damages; and

          (d) to the extent that Damages in the PRI Territory are awarded in
              favor of any of the Parties to this agreement or their Affiliates,
              PRI shall be entitled to receive all of such Damages and to the
              extent that Damages in the G(UK) Territory are awarded in favor of
              G(UK) or any of its Affiliates, PRI shall be first reimbursed for
              its costs and expenses incurred in connection with the action and
              thereafter the Partnership shall be entitled to receive 10% of the
              Damages.

          Upon the assertion of any third-party claim or other challenge against
G(UK), PRI or the Partnership (or their respective Affiliates) that may give
rise to right of indemnification under this agreement, the Person claiming a
right to indemnification (the "Indemnified Party") shall give prompt notice to
the Person alleged to have the duty to indemnify (the "Indemnifying Party") of
the existence of such claim or other challenge (provided that the failure to
give such notice in timely fashion shall not release the Indemnifying Party of
its obligations of indemnification hereunder except to the extent that the
Indemnifying Party has been prejudiced thereby) and shall give the Indemnifying
Party reasonable opportunity to control, defend and/or settle such claim at its
own expense and with counsel of its own selection; provided, however, that, the
                                                   --------  -------  ----     
Indemnified Party shall, at all times, have the right to fully participate in

parties to the extent that they are not 


                                    --26--
<PAGE>
 
contractually or legally excluded therefrom, or otherwise prejudiced in a legal
position by so doing, shall co-operate with each other and with their respective
insurers in relation to the defense of such claim or other challenge. The
Indemnifying Party shall consult with the Indemnified Party with respect to
settlement of any claim or other challenge. The Indemnifying Party shall have
the right to settle any claim or other challenge without the consent of the
Indemnified Party, provided, that, the Indemnified Party is unconditionally
                   --------  ----
released from such claim or other challenge and it is not otherwise prejudiced
by the terms of settlement. In the event the Indemnifying Party elects to defend
such claim or other challenge, the Indemnified Party may not settle such claim
or other challenge without the prior written consent of the Indemnifying Party.
If the Indemnifying Party shall, within a reasonable time after such notice has
been given, fail to defend, compromise or settle such claim or other challenge,
(or thereafter fails to diligently defend such claim or other legal challenge)
then the Indemnified Party shall have the right to defend, compromise or settle
such claim or other legal challenge without prejudice to its rights of
indemnification hereunder. Notwithstanding the foregoing, in the event of any
dispute with respect to indemnity hereunder, each party shall be entitled to
participate in the defense of such claim or other legal challenge and to join
and implead the other in any such action.

of this agreement, carry or be subject to coverage under (as a named insured)
product liability insurance (including blanket contractual liability) in an
amount of not less than $10,000,000 US combined single limit, which insurance
will be written on an occurrence policy form with an insurance carrier
reasonably acceptable to the other party. Each of G(UK) and PRI  shall, at the
request of the other, provide evidence to such requesting party of compliance
with its insurance obligations (and those of its Affiliate) under this Section
and evidence of renewals of any such policy, from time to time.

                                CONFIDENTIALITY

          10.1 Confidential Nature of Agreement:  Each Party agrees that,
without the prior written consent of the other, or except as may be required by
law or court order, the existence and terms of this agreement shall remain
confidential and shall not be disclosed to any Person other than employees and
professional advisers of such Party or its Affiliates who reasonably require
knowledge of  the existence or terms of this agreement and who are bound to such
Party or its Affiliates by a like obligation of confidentiality. Such employees
and advisors will be advised of the nature and existence of the confidentiality
undertakings of this agreement and of the applicability of such undertakings to
them and will agree to be bound hereby.

          10.2 Duty of Confidentiality:  Each Party agrees to hold in trust and
confidence (and to cause its Affiliates to hold in trust and confidence) for the
benefit of the other Parties (and their Affiliates) all Confidential Information
of such other Parties and their Affiliates and each further agrees to safeguard,
and to cause its Affiliates to safeguard, the Confidential Information of the
other (or its Affiliates) to the same extent that it does with its own


                                    --28--

confidential information and to limit and control copies, extracts and
reproductions made of such Confidential Information. No Party will, without the
express written consent of the others, directly or indirectly, use (or
authorize, permit or suffer any of its Affiliates to use) any Confidential
Information of the other Parties or of their Affiliates for any purpose other
than to implement the provisions of this agreement or in regulatory proceedings
or in litigation. No Party will disclose Confidential Information to any Person,
other than its employees or other representatives or those of its Affiliates who
have a need to know to fulfill the provisions and intent of this agreement
(where such provisions and intent cannot properly be fulfilled without such
disclosure) and who have been informed of the confidential nature of the
information and have agreed to be bound by the terms hereof.  Each Party shall
use its best efforts to prevent unauthorized use or disclosure of the
Confidential Information of the other Parties or their Affiliates and shall use
protective measures no less stringent than those used by it in its own business
to protect its own confidential information, including segregating such
information at all times from the confidential material of others so as to
prevent any commingling.

          10.3 Compulsory Disclosures:  In the event that any Party (or any of
their respective Affiliates) shall be legally compelled or required by a court
of competent jurisdiction to disclose all or any part of the Confidential
Information of another Party (or its Affiliates), it shall provide prompt notice
to the other so that such other Party (or its Affiliates) may determine whether
or not to seek a  protective order or any other appropriate remedy. If a
protective order or other appropriate remedy is not obtained before such
disclosure is required, the Party required to make disclosure will disclose only
those portions of the Confidential Information in question which it is advised
by written opinion of counsel (which opinion shall be addressed to such Party
and to the other Party), it is legally required to disclose and will exercise
its best efforts to obtain reliable assurances that confidential treatment will
be accorded such Confidential Information.

          10.4 Return of Confidential Information:  Upon termination of this
agreement, each Party shall immediately return to the other Parties all material
containing or reflecting or referring to any Confidential Information of the
other Parties or their Affiliates (including all notes, summaries, analysis or
other documents prepared or derived therefrom) and all copies thereof in any
form whatsoever under the power or control of such Party or its Affiliates,
except that one copy may be retained for legal archival purposes, and such Party
shall delete such Confidential Information from all retrieval systems and data
bases or destroy same as directed by the other Parties and furnish to the other
Parties, if requested, a certificate of a senior officer of such Party
certifying such return, deletion and/or destruction. Where this agreement is
terminated in respect of a particular Product or Products only then the
foregoing obligations shall thereupon apply to Confidential Information relating
to such Product or Products.

          11.1 Arbitration: Any controversy or claim arising out of, or relating
to, this Agreement or the breach thereof shall be referred for decision
forthwith to a senior executive of each Party not involved in the dispute. If no
agreement is reached  within 30 days of the request by one Party to the other to
refer the same to such senior executive, then such controversy or claim shall be

          12.3 Governing Law and Consent to Jurisdiction:

          (a) This agreement shall be deemed to have been made under, and shall
              be governed by, the laws of the State of New York without giving
              effect to New York's choice of law provisions.
 
          (b) Subject to Article 11 above, in connection with any action
              commenced hereunder, each of the undersigned consents to the
              jurisdiction of the state and federal courts located in New York
              City. G(UK) hereby appoints Lipha Americas, Inc., 9 W. 57/th/
              Street, New York, New York (or any successor firm or to such other
              address as they or G(UK) may designate in writing) and PRI and the
              Partnership hereby appoint Hertzog, Calamari & Gleason, 100 Park
              Avenue, New York, New York, l0017, (or any successor firm or to
              such other address as they or PRI or the Partnership may designate
              in writing), as their respective agents upon whom service of
              process may be made with the same force and effect as if service
              shall have been made personally upon them.

          12.4 Entire Agreement:  This agreement contains the entire agreement
and understanding of the Parties with respect to its subject matter and
supersedes all negotiations, prior discussions and any agreements relating to
the subject matter hereof.   This agreement may not be amended or modified
except by a written instrument signed by the Parties.

          12.5 Waiver: Any waiver of, or consent to depart from, the
requirements of any provision of this agreement shall be effective only if it is
in writing and signed by the Party giving it, and only in the specific instance
and for the specific purpose for which it has been given. No failure on the part
of any Party to exercise, and no delay in exercising, any right under this
agreement shall operate as a waiver of such right. No single or partial exercise
of any such right shall preclude any other or further exercise of such right or
the exercise of any other right.

          12.6 Counterparts:  This  agreement may be executed in identical
duplicate copies exchanged by facsimile transmission.  The Parties agree to
execute three identical original copies of the agreement after exchanging signed
facsimile versions.  Each identical counterpart shall be deemed an original, but
all of which together shall constitute one and the same instrument.

          12.7 Severability of Provisions: If, for any reason whatsoever, any
term, covenant or provision of this agreement or the application thereof to any
Party or circumstance or in any jurisdiction  is to any extent held or rendered
invalid, unenforceable or illegal, then such term, covenant or condition (a) is
deemed to be independent of the remainder of this agreement and to be severable
and divisible therefrom and its validity, unenforceability or illegality shall
not affect, impair or invalidate the remaining provisions hereof; and (b)
continue to be applicable and enforceable to the fullest extent permitted by law
in every other jurisdiction and against any Party and circumstances other than
those as to which or in respect of which it has been held or rendered
unenforceable or illegal. To the extent permitted by applicable law, each Party
hereby waives any provision of law which renders any provision of this agreement
prohibited or unenforceable in any respect.   Should any provision of this
agreement be so held to be unenforceable, such provision, if permitted by law,
shall be considered to have been superseded by a legally permissible and
enforceable clause which corresponds most closely to the intent of the parties
as evidenced by the provision held to be unenforceable.

          12.8 Assignment: Neither this agreement nor rights of a Party
hereunder may be assigned nor may the performance of any duties hereunder be
delegated without the prior written consent of the other Party. Notwithstanding
the foregoing, G(UK) and PRI may delegate from time to time some of their
respective duties hereunder to any of their respective Affiliates and, in
addition, G(UK) and PRI may license the distribution and/or subcontract the
manufacturing of a Product, in whole or in part, to any other Person which is
not an Affiliate after the prior written notice to the other Parties; provided,
                                                                      --------

shall agree in writing to be bound by the terms and conditions of this agreement
as a condition to and prior to the license and/or subcontract and that the
license and/or subcontract shall not be detrimental to the interest of the
Partnership or any other Party to this agreement in the reasonable judgment of
the Partnership or such other Party.  No such delegation, licensing or
subcontracting will relieve G(UK) or PRI, as the case may be, of any of its
obligations hereunder.  Subject to the foregoing this agreement shall be binding
upon and enure to the benefit of the parties and their respective successors and
permitted assigns.

          12.9 Non-Contravention:  Each Party represents and warrants that the
execution, delivery and performance of this agreement by it will not contravene
any other contract or agreement to which it is a Party or by which it is bound.

          12.10  Headings:  The headings of all Articles and Sections hereof are
inserted for convenience of reference only, are not intended to be full or
accurate descriptions of the contents hereof and shall not be considered part of
this agreement or affect the construction or interpretation of this agreement.

          12.11  Compliance: Where, in accordance with the provisions of this
agreement, the Affiliate of a Party is required to do or omit to do or use
reasonable commercial (or other) efforts to do or refrain from doing any act or
thing such Party shall use reasonable best commercial efforts to cause its
Affiliates to comply.
