                               [GRAPHIC OMITTED]

                               [GRAPHIC OMITTED]

Dear Stockholders of Impax and Global:

     Impax and Global have agreed to combine by a merger of Impax into Global.
The combined company will be renamed Impax Laboratories, Inc. In the merger,
the combined company will issue shares of its stock in exchange for existing
shares of Impax preferred stock and common stock and Global preferred stock, as
detailed in the chart on page 5 under the Section "What Global and Impax
Stockholders Will Receive as a Result of the Merger." Existing shares of Global
common stock will remain unchanged by the merger. Following the merger, Impax
shareholders are expected to own approximately 74% of the outstanding shares of
the combined company.

     In order to complete the merger, we must obtain the approval of each of
our companies' stockholders. You should know that certain shareholders of
Impax, who own in excess of 70% of Impax's outstanding stock, have agreed to
vote their shares in favor of the merger. In addition, Global's executive
officers and directors or their related entities who own approximately 55% of
the outstanding Global stock have indicated their intention to vote in favor of
the merger. As a result, unless these officers and directors change their
minds, stockholder approval of the merger is assured for both Impax and Global.
The boards of directors of both Impax and Global have approved the merger and
recommend that their respective stockholders vote FOR the merger proposal as
described in the attached materials. The location, date and time of your
company's special meeting, being held to consider and vote on the merger, are
set out in the applicable Notice of Special Meeting appearing immediately after
this letter.
                               ---------------
     We urge you to carefully read this joint proxy statement/prospectus,
including the section describing risk factors relating to the merger, that
begins on page 15.
                                ---------------
   Global's common stock is traded on the Nasdaq Small Cap Market under the
symbol "GLPC".

                                Sincerely,




/s/  Larry Hsu                              /s/   Barry R. Edwards

commission has approved the merger described in this joint proxy
statement/prospectus or the common and preferred stock to be issued in the
merger, nor have they determined if this joint proxy statement/prospectus is
accurate or adequate. Furthermore, the Securities and Exchange Commission has
not determined the fairness or merits of the merger. Any representation to the
contrary is a criminal offense.

first being mailed to stockholders on or about November 10, 1999.

     Global has filed a Registration Statement on Form S-4 to register with the
Securities and Exchange Commission the combined company common stock being
issued to Impax shareholders in the merger. Global also intends to file a
Registration Statement on Form S-3 to register the shares of common stock
underlying the Series 1-A and Series 1-B preferred stock being issued in the
merger. This document is part of the S-4 registration statement and constitutes
both a prospectus of Global and part of the special meeting proxy statement of
Impax and Global. As allowed by the rules of the Securities and Exchange
Commission, this joint proxy statement/prospectus does not contain all the
information you can find in the registration statement or the exhibits to the
registration statement.

     You can get a copy of any of these materials by writing or telephoning the
Secretary at Global Pharmaceutical Corporation, Castor & Kensington Avenues,
Philadelphia, Pennsylvania 19124, telephone number (215) 289-2220. If you would
like to request documents from Global, please do so by December 5, 1999, in
order for them to be delivered to you in time for the Global special meeting.
There is no charge for these requested materials.

     You should rely only on the information provided in this prospectus or any
supplement. We have not authorized anyone else to provide you with different
information. You should not assume that the information in this prospectus or
any supplement is accurate as of any date other than the date on the front of
those documents. This joint proxy statement/prospectus does not constitute an
offer to sell or a solicitation of an offer to buy securities, nor does it

                    QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: What do I need to do now?

A: After you have carefully read this joint proxy statement/prospectus, please
   sign and mail your proxy card in the enclosed return envelope as soon as
   possible, so that your shares may be represented at the appropriate special
   meeting. In addition, you may attend the special meeting in person and
   vote, whether or not you have signed and mailed your proxy card.

   If you sign and send in your proxy and do not indicate how you want to vote,
   your proxy will be counted as a vote in favor of all the proposals. If you
   do not vote or you abstain from voting, it will have the effect of a vote
   against the proposals.

Q: What do I do if I want to change my vote?

A: Just send in a later-dated, signed proxy card before the special meeting of
   your company or attend the meeting in person and vote. You also may revoke
   any proxy by written notice to the Secretary of Impax or Global, as
   appropriate, prior to your company's special meeting.

Q: If my shares are held in "street name" by my broker, will my broker vote my
   shares for me?

A: Your broker will vote your shares as to the merger only if you provide
   instructions on how to vote. You should instruct your broker to vote your
   shares, following the directions provided by your broker. If you do not
   instruct your broker to vote your shares, they will not be voted. Shares that
   are not voted will be counted as votes against the merger proposal.

Q: Should I send in my stock certificates now?

A: No. After the merger occurs, Global will mail instructions to all former
   Impax shareholders and holders of Global preferred stock for exchanging
   their stock certificates.

Q: Whom should I call with questions?

                                    SUMMARY

     This summary highlights information about the merger which we believe will
be most important to you. However, you should read the entire joint proxy
statement/prospectus, including the merger agreement and other attachments, for
a complete understanding of the merger, our business after the merger and our
securities.

</TABLE>

     Shares of Global common stock outstanding prior to the merger will
continue to represent an equivalent number of shares of common stock of the
combined company after the merger.

     We refer to the ratios for converting Impax and Global stock into stock of
the combined company as the "exchange ratios."


Tax Consequences
(See page 50)

     Fulbright & Jaworski L.L.P., counsel to Global, has expressed its opinion
that the merger will qualify as a reorganization for federal income tax
purposes. If the merger qualifies, the stockholders of Impax and Global will
generally not recognize gain for Federal income tax purposes when their shares
are converted. Because of recent changes in the Internal Revenue Code involving
preferred stock issued in a reorganization, there is some uncertainty in the
case of holders of Impax Series D preferred stock whose stock is converted into
Series 1-B preferred stock in the merger. Also, Impax shareholders will have to
pay tax on any cash received for fractional shares.


Appraisal Rights
(See page 52)

     If you own shares of Global's common stock or preferred stock, you have
"appraisal rights" under Delaware law. "Appraisal rights" allow stockholders
who object to the merger to require the company to buy their shares for their
fair value as determined by a court. A stockholder might want to exercise its
appraisal rights if it feels that the value of the shares of combined company
stock it will receive in the merger is less than the fair value of its Global
shares. On page 52, we explain what you must do to exercise these rights.

     If you own shares of Impax common stock or preferred stock, you have
appraisal rights under California law. On page 53, we explain what you must do
to exercise these rights.

Ownership of the Combined Company Following the Merger
(See page 128)

     As a result of the merger, approximately 60% of the outstanding voting
stock of the combined company will be held by seven stockholders (or their
affiliated entities). These stockholders, the amount of their ownership and the
position they will hold with the combined company are as follows.

Kingdon Capital
  Management Corporation.....  1,882,353    Representative will be member of the board of directors
</TABLE>

     Due to their stock holdings, these stockholders can exercise significant
influence over all matters requiring stockholder approval, including the
election of directors and the approval of significant corporate transactions.
This concentration of ownership may also potentially delay or prevent a change
in control of the combined company.


The Rights of Impax Shareholders Will Change as a Result of the Merger
(See page 68)

     Currently, the rights of Impax shareholders are governed by California law
and Impax's articles of incorporation and by-laws. After the merger, Impax
shareholders will become stockholders of Global (as the legal survivor of the
merger), and, therefore, their rights will be governed by Delaware law and
Global's certificate of incorporation, as amended, and by-laws. A summary of
key differences between the rights of Impax shareholders and Global
stockholders is described in this joint proxy statement/prospectus at pages
68-74.


Our Reasons for the Merger
(See page 38)

     We believe that combining our resources will enable us to be a stronger
competitor in the pharmaceuticals industry for the following reasons:

   o The combined company will have a significant increase in products under
     development and will have access to Global's well-established generic
     product sales and marketing team.

   o The combination of marketing and product development expertise in the
     same company will lead to better strategic planning in product
     development.

   o The merger provides the combined company with greater financial resources
     and enhanced borrowing capabilities than each company had on its own. This
     should enable the combined company to afford to have more products under
     development and to spend more resources on commercializing and marketing
     its products.

   o The management and directors of Global and Impax believe that the merger
     will result in significant opportunities for cost savings due to economies
     of scope and scale and the elimination of duplicative expenditures; for
     revenue growth due to greater sales and marketing capabilities; and for
     technological development due to the combined efforts of our technical
     personnel.

Conditions to the Merger
(See page 58)

Completion of the merger requires:

     o  approval of the merger proposal by the Impax shareholders;

     o  approval of the merger proposal by the Global stockholders;

     o  absence of any law or injunction preventing the merger or causing an
        adverse effect on the business, financial condition or regulatory status
        of either company or the combined company;

     o  approvals from government regulators;

     o  not more than 10% of the value of Global's or Impax's outstanding stock
        have dissented as to the merger proposal;

     o  receipt by Impax and Global of satisfactory environmental evaluations of
        the other's facilities; and

     o  absence of events which adversely affect or are reasonably likely to
        adversely effect the business, financial condition or regulatory status
        of either company.

     Other than conditions pertaining to stockholder approvals and the legality
of the transaction, either of Global or Impax could elect to waive conditions
to its own performance and complete the merger.


Restrictions on Alternative Transactions
(See page 56)

     The merger agreement limits the ability of each of our boards of directors
to solicit or participate in discussions with any third party about
transactions alternative to the merger, other than as may be necessary for the
board to fulfill its fiduciary obligations. In addition, the merger agreement
requires each company to seek stockholder approvals required to complete the
merger even if its board of directors was to change its recommendation of the
merger.

     The termination fees provided for in the merger agreement, which are
discussed under the following section called "Termination of the Merger
Agreement," could deter either Impax or Global from entering into an
alternative transaction by making it more difficult or expensive.


Termination of the Merger Agreement
(See page 62)

     Global and Impax mutually may agree to terminate the merger agreement at
any time. In addition, either company may terminate the merger agreement if
specified events do or do not occur. These include:

     o  if the merger is not completed by December 31, 1999;

     o  if a court or government regulator permanently prohibits the merger;

     o  if a condition to a company's obligation to consummate the merger cannot
        be satisfied;

     o  if the required stockholder approvals are not obtained;

     o  if the board of directors of the other company withdraws or adversely
        changes its approval or recommendation in favor of the merger, or if
        that board of directors recommends an alternative transaction with a
        third party;

     o  if the other company does not comply in any material respect with any of
        its obligations under the merger agreement or its representations and
        warranties are false in a material respect; or


                                       7
<PAGE>

     o  if a third party commences a tender offer or exchange offer for 10% or
        more of the outstanding common stock of Impax or Global, and the board
        of that party recommends that the stockholders tender their shares in
        such offer.

     Global or Impax must pay to the other its expenses incurred in connection
with the merger, up to $500,000, plus a termination fee of $500,000 if the
merger agreement terminates because of any of the last 3 events just listed.
Additionally, Global must pay to Impax an additional $500,000 if the merger
agreement terminates due to Global's failure to obtain the requisite
stockholder approval for the merger.


Opinion of Global Financial Advisor
(See page 41)

     Global received an opinion from Gruntal & Co., L.L.C., its financial
advisor, to the effect that as of the date of such opinion, the consideration
to be received by the Impax shareholders was fair, from a financial point of
view, to the holders of Global common stock. Gruntal subsequently affirmed its
opinion on November 8, 1999. We have included the opinion in this joint proxy
statement/prospectus as Annex B. Global urges its stockholders to read the
opinion of Gruntal & Co., L.L.C. in its entirety.

     Impax did not solicit an opinion of a financial advisor.


Expected Accounting Treatment
(See page 49)

     The merger is intended to be accounted for as a reverse acquisition of
Global by Impax under the purchase accounting method for financial reporting
purposes in accordance with generally accepted accounting principles. Following
the merger, the combined company will report on the basis of Impax's historical
financial statements.


Board of Directors and Management of the Combined Company Following the Merger
(See page 120)

     Upon completion of the merger, the combined company's board of directors
will consist of the following ten members, each of whom is elected based on the
stated merger agreement provision:




<TABLE>

Nigel Fleming and a second mutually agreed        Two persons mutually selected by the
upon board member                                 current boards of Impax and Global
</TABLE>

     Certain significant shareholders of Impax and Global have entered into a
shareholders' agreement committing these persons to vote their shares for the
next three years for the election as directors of the individuals designated
each year by the members of the current boards of Global and Impax.

     The current members of the board of directors of Global and of Impax, as a
group, also each have the right to designate one observer to the combined
company board of directors.

     When the merger is completed, the following persons will serve as

                     Officer
</TABLE>

Additional Compensation for Executive Officers as a Result of the Merger
(See page 122)

     In connection with the appointment of Charles Hsiao as Chairman and
Co-Chief Executive Officer, Barry R. Edwards as Co-Chief Executive Officer, and
Larry Hsu as President and Chief Operating Officer, each of them is expected to
enter into an employment agreement with the combined company when the merger is
completed. These agreements provide that Dr. Hsiao, Mr. Edwards and Dr. Hsu
will each receive an annual salary of $175,000 and will be eligible for a bonus
as determined by the board of directors. Each agreement will be for an initial
term of three years, and be automatically renewed for successive one year terms
unless either party delivers a written notice of termination at least six
months prior to the expiration of the initial term or any renewal term. If the
combined company terminates the employment of Dr. Hsiao, Mr. Edwards or Dr. Hsu
without cause, the executive leaves the combined company for good reason, or a
change in control of the combined company occurs, the executive will be
entitled to certain severance payments.

     In addition, Mr. Edwards' employment agreement provides that he will
receive an option to purchase 270,000 shares of common stock at the prevailing
market price at the time the option is granted. It is expected that the option
will be granted immediately after the merger is completed. Global's Board of
Directors, Mr. Edwards and certain persons who are a majority of the
individuals designated to become directors of the combined company have agreed
that Mr. Edwards will not receive any additional stock options for the next
three years. The shares covered by this option vest and become exercisable on
the following schedule: (i) first year -- 0%; (ii) second year -- 10%; (iii)
third year -- 40%; (iv) fourth year -- 50%.


The Special Meetings (See page 30 as to Global and page 33 as to Impax)

     Global. The Global special meeting will be held at 10:00 a.m., on December
13, 1999 at the offices of Fulbright & Jaworski L.L.P., 666 Fifth Avenue, 24th
Floor, New York, New York. At the meeting, Global stockholders will be asked to
vote on a proposal to adopt the merger agreement, which will approve the merger
and the following actions:

   (a) an amendment to the Global certificate of incorporation to change the
       name to "Impax Laboratories, Inc." and to increase the number of
       authorized shares of common stock from 17,000,000 to 50,000,000 shares.
       The proposed amendment to the restated certificate of incorporation will
       not be effective unless the merger is completed. We have included the
       form of the proposed amendment to the restated certificate of
       incorporation in this joint proxy statement/prospectus as Appendix E.

   (b) the election of directors of the combined company; and

   (c) the adoption of a new equity incentive plan. This plan will generally
       enable the board of directors of the combined company (or a committee of
       the board) to grant stock options, stock appreciation rights and stock
       bonuses to officers, employees, consultants and directors of the
       combined company. In addition, non-employee directors of the combined
       company will receive

The Companies
(See page 75 as to Global and page 100 as to Impax)


Global Pharmaceutical Corporation
Castor & Kensington Avenues
Philadelphia, Pennsylvania 19124
(215) 289-2220

     Global is a specialty pharmaceutical company engaged principally in the
development, manufacture and marketing of solid oral generic prescription drugs
in smaller, niche markets. The niche markets generally have fewer competitors
and can result in higher profit margins as compared to larger market products.
The company is headquartered at its 113,000 square-foot, research and
manufacturing facility located in Philadelphia, Pennsylvania, and is
incorporated in Delaware.

     Global was formed in April 1993 to acquire the manufacturing plant
equipment and certain related assets and liabilities of Richlyn Laboratories,
Inc. These assets included Richlyn's Abbreviated New Drug Applications, known
as ANDAs, New Drug Applications, known as NDAs, and New Animal Drug
Applications, known as NADAs. Richlyn operated a generic pharmaceutical
business from 1947 to 1992 when its facility was closed for failure to comply
with FDA regulations concerning current Good Manufacturing Practices, known as
cGMP.

     From its inception through 1997, Global devoted substantially all of its
efforts to improving and renovating its facility, and establishing policies and
procedures to bring its manufacturing facility into compliance with cGMP.
Global received FDA approval for its first product, Tetracycline Hydrochloride
250 mg capsules, and began shipping products in September, 1997. Global is now
marketing 25 generic products, with Global's products being sold by all of the
20 largest pharmaceutical wholesalers, in terms of sales volume.

     Until the quarter ended December 31, 1997, when Global became operational,
Global was considered a development stage company. The year ended December 31,
1998, was Global's first full year of operations with $4,401,000 in revenues
and net loss applicable to common stock of ($4,755,000). Revenues for the six
months ended June 30, 1999 were $4,217,000 and Global's net loss applicable to
common stock for the six months ended June 30, 1999 was ($3,020,000). Global
had an accumulated deficit of $24,137,000 at June 30, 1999.

Impax Pharmaceuticals, Inc.
30831 Huntwood Avenue
Hayward, California 94544
(510) 471-3600


     Impax is engaged in developing and commercializing oral pharmaceuticals
utilizing controlled-release drug delivery technologies. Controlled-release
pharmaceuticals are designed to reduce the frequency of drug administration,
improve the effectiveness of the drug treatment, ensure greater patient
compliance with the treatment regimen and reduce side effects by releasing drug
dosages at specific times and in specific locations in the body.


     Impax is applying its patented and non-patented drug delivery technologies
initially to develop generic versions of high sales volume, controlled-release
brand name pharmaceuticals. Impax has submitted ANDAs to the FDA covering
generic versions of three different branded, prescription pharmaceuticals. The
ANDA for Pentoxyfylline ER tablets was approved in August 1999 and was Impax's
first ANDA approval. Impax currently has 15 additional controlled-release
products under development.


     Two other products are being developed by Impax for potential NDA filings.
For these products, Impax is using its drug delivery technology to develop
improved formulation of brand name drugs.


     The extensive technology background and product development experience of
the founders allow Impax to compete in an area that requires highly-skilled
employees. Impax has developed four drug delivery systems, one of which has
already been licensed to a large multi-national pharmaceutical company.



                          COMPARATIVE PER SHARE DATA


     The following table sets forth historical per share data for Global and
Impax, pro forma data for Global giving effect to the proposed merger under the
purchase method of accounting, and equivalent pro forma per share data for
Impax. The information presented should be read in conjunction with the
historical financial statements and related notes of Impax and of Global, the
Unaudited Pro Forma Combined Financial Information and related notes, and the
Selected Historical Financial Information, each appearing elsewhere in this
joint proxy statement/prospectus. Comparative pro forma data have been included
for comparative purposes only and do not purport to be indicative of (1) the
results of operations or financial position which actually would have been
obtained if the merger had been completed at the beginning of the period or as
of the date indicated or (2) the results of operations or financial position
which may be obtained in the future. Impax equivalent pro forma per share
amounts are calculated by multiplying the pro forma combined net loss per share
and the pro forma combined book value per share by 3.3358, which is the number
of Global shares issued for each share of Impax common stock. Neither Global
nor Impax paid cash dividends for the periods presented.

                                 RISK FACTORS

     If you approve the merger, your original investment in Impax or Global, as
applicable, will represent an investment in the combined company. The merger of
Global and Impax involves a high degree of risk. You should consider carefully
the following risk factors, as well as the other information included in this
joint proxy statement/prospectus, in deciding whether to approve the merger.

Even if the merger is completed, we may fail to realize benefits from combining
our companies. We believe that an important benefit from the merger is that the
combined company will utilize the strongest elements of the management,
strategy, and operations of each of Global and Impax. We may not successfully
integrate the operations of Impax and Global without encountering difficulties
or losing key personnel, and the benefits that we expect from this merger may
not be realized. Even if the merger is completed, it may not result in combined
results of operations and financial condition better than what would have been
achieved by Global or Impax independently.

If the merger is completed, our costs related to the merger may be
significant. Global and Impax, together, expect to incur merger-related
expenses of approximately $700,000 in the year ending December 31, 1999, as the
merger is expected to close in the fourth quarter. These expenses include costs
for legal and accounting fees, costs of financial printing, listing fees and
other related costs. This estimate does not include any costs associated with
restructuring, integrating or consolidating the operations of the two
companies. This amount is only an estimate and may change. In addition, we may
incur unanticipated expenses in integrating Impax's and Global's businesses. We
expect that the savings from the elimination of duplicative expenses and the
realization of other efficiencies related to this integration may offset any
additional expenses in the future. However, we may not achieve a net benefit in
the near future, or at all.

The combined company will continue to experience operating losses, initially at
greater levels than either of the individual companies, which makes our future
profitability uncertain. The business of the combined company may never be
profitable. Each of Impax and Global has generated minimal revenues to date and
has experienced operating losses since inception. As of June 30, 1999, the
accumulated deficit of Impax was $14,909,000 and the accumulated deficit of
Global was $24,137,000. As of July 31, 1999, Global also had outstanding
indebtedness in an aggregate principal amount of $3,005,000 at interest rates
ranging from 2% to 9% annually. Since each company is experiencing operating
losses, the aggregate cash drain on the combined company is increased. It is
also possible that either company, if it remained independent, would be
profitable at an earlier time than the combined company will be profitable, if
at all. To remain operational, we must:

   o develop new products which have attractive market demand;

   o obtain regulatory approvals of newly developed products;

   o properly receive, warehouse and store raw materials and supplies;

   o maintain work in progress in compliance with regulatory requirements and
     properly store finished goods;

   o properly manufacture various formulations, dosages and configurations of a
     potentially broad product line;

   o meet strict security requirements for virtually every activity undertaken
     at the plant;

   o maintain appropriate laboratory, quality control and quality assurance
     practices and procedures; and

   o comply with the many complex governmental regulations that deal with
     virtually every aspect of our proposed business activities.

If we are unable to obtain additional financing, we may need to modify our
business operations and plans by spending less money on research and
development programs, developing fewer products and filing fewer drug
applications with the FDA. Upon completion of the merger, the combined company
will have approximately $7 million of unrestricted funds. We estimate that
these funds will be sufficient for the next 9 months of operations at our
planned expenditure levels. The exact amount and timing of future capital
requirements will depend on many factors, including continued progress with our
research and development


                                       15
<PAGE>

programs, expansion of such programs and, ultimately, the approval and launch
of the combined company's products. The combined company may not be successful
in obtaining additional capital in amounts sufficient to continue to progress
and fund our operations. Additional financing also may not be available to us
on terms favorable to the combined company or our stockholders, or at all. In
the event that adequate funds are not available, our business operations and
plans may need to be modified. This could result in less money being spent on
research and development programs, fewer products being developed and at a
slower pace, and fewer drug applications being filed with the FDA.

If we need to raise additional capital for expansion, our stockholders may
sustain dilution in ownership or otherwise be adversely affected by
arrangements made with other companies. The combined company may need to raise
additional capital in the future to fund its planned expansion. To the extent
the combined company raises additional capital by issuing equity securities,
ownership dilution to stockholders will result. To the extent the combined
company raises additional funds through strategic alliance and licensing
arrangements, we may be required to relinquish rights to certain of our
technologies or product candidates, or to grant licenses on terms that are not
favorable to the combined company, either of which could reduce the value of
the combined company.

If the net income per share of Global common stock is reduced because of the
additional stock being issued in the merger, it could reduce the market price
of the Global common stock. We expect to issue an additional 16,904,114 shares
of Global common stock and an additional 170,000 shares of Global preferred
stock in connection with this merger. The issuance of these shares may reduce
the net income per share of Global common stock, including below levels
currently anticipated and published by industry analysts. This could reduce the
market price of the Global common stock after the merger unless we can achieve
revenue growth, cost savings and other benefits from the merger that will
offset the effect of the issuance.

Because the exchange ratios are all fixed, stockholders will not know the
market price value of the stock they will receive or which will be issued in
the merger at the time when they vote on the merger. Each of the exchange
ratios are fixed. The number of combined company shares to be received by Impax
and Global stockholders will not change, even if the market price of Global
common stock changes. As a result, Impax shareholders will not know the value
of the combined company stock they will receive in the merger and Global
stockholders will not know the value of the combined company stock to be issued
in the merger, at the time when they vote on the merger proposal. In addition,
neither Impax nor Global has the right to terminate the merger agreement based
upon any adverse fluctuation in Global's stock price. From July 27, 1999 (the
day of the public announcement of the merger) through November 5, 1999, the
Nasdaq market price per share of Global common stock ranged from $3.50 to $5.625
and closed at $4.25 on November 5, 1999.

Control of the combined company will be held by a limited number of
shareholders, most of whom are Impax shareholders who can exercise significant
influence over all matters requiring stockholder approval and thereby limit
your power to influence corporate action. As a result of the merger, the
shareholders of Impax will own approximately 74% of the outstanding voting
stock of the combined company. Moreover, approximately 64% of the outstanding
voting stock of the combined company will be held by seven stockholders. These
stockholders can exercise significant influence over all matters requiring
stockholder approval, including the election of directors and the approval of
significant corporate transactions. This concentration of ownership may also
potentially delay or prevent a change in control of the combined company. In
addition, holders of approximately 64% of the outstanding voting stock of the
combined company have entered into an agreement committing them to vote their
shares of stock for the next three years for the election as directors of the
individuals designated each year by the current boards of Global and Impax. In
this regard, you should also review the Description of Global's Capital Stock
Following the Merger section later in this joint proxy statement/prospectus.

If Impax shareholders approve the merger, their company will become subject to
an outstanding court order governing manufacture of products which may
adversely affect product introduction plans and results of operations. On May
25, 1993, the United States District Court for the Eastern District of
Pennsylvania issued an order against Richlyn Laboratories, Inc. that, among
other things, permanently enjoined Richlyn from selling any drug manufactured,
processed, packed or labeled at its Philadelphia facility unless it met certain
stipulated conditions. When Global acquired the facilities and drug
applications of Richlyn, it became


                                       16
<PAGE>

subject to the conditions in that court order. After the merger, the combined
company will continue to be subject to the court order. The order requires, in
part, that FDA find that products manufactured, processed and packed at the
Richlyn facility conform with FDA regulations concerning cGMP before the
products can be marketed.

     Although Global was informed in January 1998 that product by product
inspection was no longer required for Global to manufacture and sell products,
the FDA has the continuing authority to reverse or reconsider its position and
again require product by product inspection and prior authorization. Requiring
such inspection and authorization would subject Global to a higher level of
scrutiny than is standard for the generic pharmaceutical manufacturing
industry. Any reversal or reconsideration by FDA will delay product
introduction plans.

     The order against Richlyn also requires that Global hire and retain a
person, subject to FDA approval, who is qualified to inspect its drug
manufacturing facilities to determine that its methods, facilities and controls
are operated and administered in compliance with cGMP. This person must examine
all drug products manufactured, processed, packed and held at Global's facility
and certify in writing to the FDA Global's compliance with related cGMP. In
addition to the cost and expense of this examination, Global may not be able to
maintain compliance with cGMP, which would severely restrict its operations.

If the Global stockholders approve the merger, their company may have
additional exposure to patent infringement litigation as a result of Impax's
product development efforts, which could adversely affect our product
introduction efforts and be costly. The patent position of pharmaceutical firms
involves many complex legal and technical issues and has recently been the
subject of much litigation. There is no clear policy establishing the breadth
of claims allowed or the degree of protection afforded under such patents.
During the past several years, there is an increasing tendency for the
innovator of the original patented product to bring patent litigation against a
generic drug company. This litigation is often initiated as an attempt to delay
the entry of the generic drug product and reduce its market penetration.

     As of the date of this joint proxy statement/prospectus, Impax has
submitted three filings for new generic drug applications with the FDA, and is
expected to submit additional applications. Consequently, it is possible that
Impax, and, if the merger is approved, the combined company, could become
subject to patent infringement claims or litigation as a result of its product
development. If a patent infringement claim is asserted, the combined company
may incur substantial legal fees in defending itself. Any such claim or
litigation will likely defer the FDA approval and marketing of the product and
could result in a complete barrier to such product's entry into the market.

If certain holders of our equity exercise their rights to acquire shares of
common stock, it may lower the future value of the common stock. Upon
completion of the merger, there will be a total of 220,000 shares of
outstanding Series 1 preferred stock. These shares presently are convertible,
at any time at the option of their holders, into an aggregate of 13,841,720
shares of our common stock. The shares of preferred stock also have
anti-dilution protections, if the Company were to issue stock for a price below
stated levels, which could make them convertible into additional shares of
common stock.

     Upon completion of the merger, there will be outstanding warrants and
options to purchase an aggregate of 6,053,329 shares of combined company common
stock at exercise prices ranging from $0.75 to $13.175 per share of common
stock. In addition, under Global's arrangement with Merck KGaA, a German
company, Global issued warrants which are exercisable for 40,000 shares of
common stock for each aggregate $1 million in gross profit, if any, earned by
Global under an agreement with a subsidiary of Merck KGaA (up to a total of
700,000 shares of common stock). The exercise price for these warrants and
options may be at prices below the then trading market price for the combined
company's common stock. Consequently, any exercise of these options or warrants
could dilute the future value of our common stock.

If the combined company issues additional preferred stock it could adversely
affect the rights of holders of our common stock. After the merger, the board
of directors of the combined company will have the authority to issue up to an
additional 1,780,000 shares of its preferred stock and to determine the price,
rights, preferences and privileges of those shares (except that the rights,
preferences and privileges may not be more favorable to the stockholder than
the Series 1 preferred stock, without the approval of the Series 1 preferred


                                       17
<PAGE>

stock), without any further vote or action by the stockholders. Preferred
stockholders could adversely affect the rights of holders of common stock by:

       o   exercising voting, redemption and conversion rights to the detriment
           of the holders of common stock;

       o   receiving preferences over the holders of common stock regarding
           assets or surplus funds in the event of our dissolution or
           liquidation;

       o   delaying, deferring or preventing a change in control of our company;

       o   discouraging bids for our common stock at a premium over the market
           price of the common stock; and

       o   otherwise adversely affecting the market price of the common stock.

                        CAUTIONARY STATEMENT CONCERNING
                          FORWARD-LOOKING STATEMENTS

     In this joint proxy statement/prospectus, we have made forward-looking
statements relating to the future results of each of our companies and the
combined company. These statements are based on our estimates and assumptions
and are subject to a number of risks and uncertainties. Forward-looking
statements are preceded or followed by the words "anticipates," "believes,"
"estimates," "expects," "hopes," "targets" or similar expressions.

     The future results of the combined company could be affected by subsequent
events and could differ materially from those expressed in the forward-looking
statements. If further events and actual performance differ from our
assumption, actual results could vary significantly from the performance
projected in the forward-looking statements.

     The following important factors, along with those discussed elsewhere in
this joint proxy statement/prospectus, could affect the future results of the
combined company and could cause those results to differ materially from those
expressed in the forward-looking statements:

   o the timing of, and regulatory and other conditions associated with, the
     completion of the merger and the ability of the combined company to combine
     operations and obtain revenue enhancements and cost savings following the
     merger.

   o materially adverse changes in economic conditions in the markets served by
     our companies;

   o material changes in available technology;

   o the extent, timing, success and overall effects of competition from others
     in the pharmaceutical markets; and

   o the success and expense of our efforts and those of our suppliers,
     customers and business partners in achieving year 2000 compliance.

              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

     The following sets forth certain historical financial information of
Global and Impax on an unaudited pro forma basis after giving effect to the
merger on a "reverse acquisition purchase" basis (as if Impax had acquired
Global). The unaudited pro forma combined statement of operations includes the
results of operations of Global and Impax for the respective periods presented
and gives effect to pro forma adjustments as if the merger had occurred on
January 1, 1998. The unaudited pro forma combined balance sheet includes the
historical balance sheet of Global and Impax as of June 30, 1999 and gives
effect to the pro forma adjustments as if the merger had occurred on June 30,
1999. This data should be read in conjunction with the selected historical
financial information, the comparative per share data and the separate
historical financial statements of Global and Impax and the notes thereto
included elsewhere in this joint proxy statement/prospectus. The unaudited pro
forma combined financial statements are not necessarily indicative of the
operating results that might have occurred had the merger actually taken place
on January 1, 1998 or the actual financial position had the merger been
consummated on June 30, 1999 and should not be construed as representative of
future operations. Management does not expect significant changes to the
preliminary valuation of the transaction, however, the final purchase price
allocation could be different from the amounts reflected in the unaudited pro
forma combined information. In addition, the unaudited pro forma combined
financial information gives effect only to the adjustments set forth in the
accompanying notes and does not reflect any restructuring costs, nor any
potential cost savings or other synergies that management expects to realize as
a result of the merger.

                   NOTES TO THE UNAUDITED PRO FORMA COMBINED
                           STATEMENTS OF OPERATIONS:
            (dollars in thousands, except share and per share data)

     a. Adjustments to the Pro Forma Combined Statement of Operations for the
year ended December 31, 1998 and the six months ended June 30, 1999 in
connection with the proposed merger are presented below:

     1. Management believes $48 of the excess fair value over book value of
Global's net assets is related to inventory. We have not reflected any
adjustment to cost of sales in the unaudited pro forma combined statement of
income for the year ended December 31, 1998 or the six months ended June 30,
1999 with respect to the fair value adjustment to Global's inventory as any
adjustment is considered to be a non-recurring charge directly related to this
transaction.

     2. As a result of recording property, plant and equipment at fair value,
depreciation expense is increased on a pro forma basis.

     3. Adjustment reflects the amortization of the amount of the purchase
price allocated to identified intangible assets. Amortization was calculated on
the straight-line basis using useful lives between 3 and 8 years.

     4. Reflects the pro forma impact of the amortization of goodwill.
Amortization was calculated on the straight-line basis over ten years.

     b. Shares used in the per share calculation reflect 16,840,734 shares as
of December 31, 1998 (16,904,114 shares as of June 30, 1999) issued to Impax
shareholders as if they were outstanding from the beginning of the period
presented and 450,000 Global shares following the conversion of Global Series C
preferred stock into common stock as if the conversion had occurred at January
1, 1998. Impax shares are calculated using 1,990,000 shares of series A and B
preferred stock as of December 31, 1998 (2,009,000 shares as of June 30, 1999)
and 2,147,362 shares of common stock converted at the exchange ratio of 3.3358
per share and 519,631 shares of series C preferred stock converted at the
exchange ratio of 5.849 per share. Global shares are calculated using 9,000
shares of series C preferred stock converted at the exchange ratio of 50 per
share. Shares used in the pro forma income (loss) per share basic and diluted
calculation for the year ended December 31, 1998 are as follows:

- ------------
* Because there are pro forma net losses in both the six-month period ended
  June 30, 1999 and the year ended December 31, 1998, only the common shares
  outstanding have been used to calculate both the basic earnings per share
  and diluted earnings per share as the inclusion of the potential common
  shares would be anti-dilutive.

Note: In-process research and development costs in the amount of $1,425, which
will be written off immediately after the transaction is completed, have been
excluded from these unaudited pro forma combined statements of operations.

           NOTES TO THE UNAUDITED PRO FORMA COMBINED BALANCE SHEET:
            (dollars in thousands, except share and per share data)

     Because the merger will be accounted for as a reverse acquisition purchase
and Impax, which is treated as the acquirer for accounting purposes, is
receiving Global common stock and preferred stock rather than Global's assets
and liabilities, the fair market value of the Global common stock and preferred
stock outstanding for a reasonable period of time before and after the
announcement of the merger determines the purchase price for accounting
purposes. For purposes of the pro forma statements, the purchase price for
Global consists of the following:



<TABLE>
<S>                                                                <C>

</TABLE>

     The average market value of Global common stock for a reasonable period of
time before and after the announcement of the merger was $3.925 per share and
there were 7,254,053 common shares issued and outstanding. There were also
9,000 shares of Global Series C preferred stock and 50,000 shares of Global
Series D preferred stock outstanding of the date of acquisition with an
aggregate fair value of $11,578. The fair value of Global stock options and
warrants was determined using the Black-Scholes option pricing model. The fair
value of each option and warrant was estimated on the date of grant with the
following assumptions: (i) no expected dividend yield in 1999, (ii) expected
stock price volatility of 108.26%, (iii) weighted average risk free interest
rate of 5.89% and (iv) expected life of option of five years in 1999.

     The direct expenses of the purchase consist primarily of legal, accounting
and other fees.

     1. For purposes of determining the pro forma effect of the acquisition on
the combined financial statements, the fair value of Global's net assets have
been estimated in accordance with Accounting Principles Board Opinion No. 16:

     Additionally as part of the purchase price allocation, the Global
historical additional paid-in capital balance of $25,106(1h) and accumulated
deficit of ($24,137)(1i) are written off.

     2.  Purchased in-process research and development represents the value
assigned in a purchase business combination to research and development
projects of the acquired business that were commenced, but not yet


                                       25
<PAGE>

completed, at the date of acquisition and which, if unsuccessful, have no
alternative future use in research and development activities or otherwise. In
accordance with Statement of Financial Accounting Standards No. 2, "Accounting
for Research and Development Costs," as interpreted by FASB Interpretation No.
4, amounts assigned to purchased in-process research and development meeting
the above criteria must be charged to expense at the date of consumption of the
purchase business combination. In this regard, the company estimates charges
for purchased in-process research and development of $1,425 with respect to the
merger. The company has not reflected any adjustments to the pro forma
statements of operations for the year ended December 31, 1998 or the six months
ended June 30, 1999 as any adjustment is considered to be a non-recurring
charge directly related to this transaction. The impact of the write-off of
in-process research and development has been reflected in stockholders' equity
as at June 30, 1999. The company believes that the assumptions and forecasts
used in valuing purchased in-process research and development are reasonable.
No assurance can be given, however, that future events will transpire as
estimated. As such, actual results may vary from the projected results.

     The valuation of in-process research and development followed established
pharmaceutical industry practices used to value and manage in-process research
and development. A simplified model of that valuation methodology is as
follows:

        Cash Flows from Successful Completion
Less:   Cash Flows to Complete
Less:   Return on assets Employed
        -------------------------------------
Equals: Adjusted Cash Flows
Times:  Probability of Technical Success
        -------------------------------------
Equals: Risk Adjusted Cash Flows
Times:  Present Value Factor
        -------------------------------------
Equals: Fair Value

     Cash Flows from Successful Completion represents the estimated future
revenues forecast to be earned over the life of the product less the costs and
expenses required to generate those revenues, assuming successful completion of
the project in process. Cash Flows to Complete represents the estimated future
research and development costs required to complete the project, assuming the
project is ultimately successful. Return on Assets Employed represents an
allocation of the estimated future profits from the product to existing assets,
including identifiable intangible assets, thereby ensuring that all appropriate
future cash flows are attributed to existing assets for purposes of determining
their fair value. Probability of Technical Success represents management's
assessment of all risks associated with successfully completing a given
project.

     Management has identified four products which have been valued as
in-process research and development. Management estimates that these products
range from 12% to 87% complete. In the aggregate, these products will require a
total of approximately $1,225,000 of research and development expenditures to
complete. Estimated remaining research and development expenditures for
individual products range from $30,000 to $450,000.

     New product development efforts for generic drugs generally involve four
main areas:

     1. Pre-formulation

     2. Formulation development

     3. Method development and validation

     4. Bioequivalency

     5. Regulatory filing

     o  Pre-formulation involves analytical testing of the reference product,
        sourcing of necessary ingredients and review of literature searches to
        aid in formulation development.

     o  Formulation development involves the lab scale production of
        experimental batches to determine the optimal formula or formulas which
        best match the desired characteristics of the reference product. This
        stage ends with production of pivotal batch(es) for bioequivalency
        testing.


                                       26
<PAGE>

     o  The method development and validation stage involves the development of
        the manufacturing process and the validation that the process creates
        the appropriate results.


     o  Bioequivalence testing involves the comparative evaluation of the test
        and reference products in human volunteers according to preset
        protocols. Typically this is the most costly phase of new product
        development.


     o  Regulatory filing involves collection, assembly and review of all of the
        information and data required for the applicable regulatory filing with
        the FDA.


     For one compound, the Company needs to complete phases 4 and 5. For two of
the compounds, the Company needs to complete phases 2 through 5. For one of the
compounds, the Company needs only to revalidate the method.


     Commercialization is expected to be achieved in 2001 for one of the
compounds and in 2002 for the remaining three. For all of the above compounds
the brand name drug patent has previously expired.

     The combined company is required to redeem the Series 1-A and Series 1-B
preferred stock, on March 31, 2004, at a price per share equal to $100 plus all
declared but unpaid dividends. The holders of the Series 1-A and 1-B preferred
stock can also require the redemption of their preferred stock upon the
happening of certain events, including the sale of the combined company or its
assets, the elimination of a public trading market for shares of its common
stock, or the insolvency of or bankruptcy filing by the combined company.

     4. The unaudited pro forma combined financial information does not give
effect to any one-time charges, restructuring costs, nor any potential cost
savings, revenue enhancements or other synergies that could result from the
merger. To the extent that any restructuring costs are accounted for as accrued
liabilities and included in the allocation of the purchase price consideration,
goodwill would increase and the pro forma net loss included in the unaudited
pro forma combined statement of income would increase as a result of increased
amortization expense.

                             THE SPECIAL MEETINGS


The Global Special Meeting

When and where the Global special meeting will be held

     This joint proxy statement/prospectus solicits, on behalf of the Global
board, proxies from the holders of Global common stock, Series C preferred stock
and Series D preferred stock to be voted at the Global special meeting, to be
held as follows:

   Monday, December 13, 1999
   10:00 a.m.
   Fulbright & Jaworski L.L.P.
   666 Fifth Avenue
   24th Floor
   New York, New York

     Proxies solicited will also be voted at any adjournment or postponment of
the Global special meeting. We first mailed this joint proxy
statement/prospectus and the form of proxy to Global stockholders on or about
November 10, 1999.


What will be voted on at the Global special meeting

     At the Global special meeting, Global stockholders will consider and vote
on a proposal to approve and adopt the merger agreement including the merger of
Impax and Global. By voting to approve the merger, Global stockholders will be
voting to approve the following items:

(1) an amendment to Global's certificate of incorporation to change the name
from "Global Pharmaceutical Corporation" to "Impax Laboratories, Inc." and to
increase the number of shares of Global common stock authorized for issuance to
50,000,000 shares.

The merger agreement provides for the issuance of approximately 31.5 million
shares of common stock (including shares of common stock issuable upon
conversion of preferred stock being issued) to the Impax shareholders. An
additional 3,798,142 shares will be reserved for issuance upon the exercise of
outstanding options and warrants held by Impax equity holders. Global currently
has 17,000,000 shares of common stock authorized for issuance, of which
approximately 12,411,890 shares are outstanding or already reserved for
issuance. The proposed amendment to the certificate of incorporation will
increase that number to 50,000,000 authorized shares to permit the issuance of
the shares to the Impax shareholders. This amendment will also permit the
combined company to reserve for issuance the 2,400,000 shares of common stock
covered by the proposed Impax Laboratories, Inc. 1999 Equity Incentive Plan
approximately 1,930,094 shares of which will be issuable upon the exercise of
outstanding options held by Impax employees and directors. Finally, Global's
board believes it would be desirable to increase the number of shares of
authorized Global common stock to make available additional shares for possible
employee benefit plan issuances, acquisitions, financings and for other
corporate purposes that may arise. The name change to "Impax Laboratories,
Inc." is deemed desirable in order to more fully utilize the good will
associated with the "Impax" name.

(2) the election of certain named individuals to serve as directors of the
combined company.

Pursuant to the terms of the merger agreement, the board of directors of the
combined company after the merger will consist of Charles Hsiao, Barry R.
Edwards, Larry Hsu, three individuals selected by the current members of the
Impax board, two individuals selected by the current members of the Global
board and two individuals mutually selected by the current members of the
Global and Impax boards. The following persons have been selected as the
initial directors of the combined company after the merger, occupying the
director seat positions indicated:

     Information regarding these individuals can be found in the section
entitled "Management of the Combined Company" appearing on page 120 of this
joint proxy statement/prospectus.


(3) the adoption of the new Impax Laboratories, Inc. 1999 Equity Incentive
Plan.


As required by the merger agreement, the Global board has adopted, subject to
approval by the Global stockholders of the merger proposal, a new equity
incentive plan entitled "The Impax Laboratories, Inc. 1999 Equity Incentive
Plan." Under the 1999 Equity Incentive Plan, the combined company may award
incentive and non-statutory stock options, stock appreciation rights and stock
bonus awards to officers, employees, directors and consultants of the combined
company and its affiliates. The compensation committee of the board of
directors (or, in the case of awards to non-employee directors, the board) will
administer the 1999 Equity Incentive Plan and determine, subject to the
provisions of the 1999 Equity Incentive Plan, who will receive awards, the
types of awards to be made and the terms and conditions of each award. Subject
to adjustment to reflect stock dividends and other capital changes, the maximum
number of shares of combined company common stock which may be issued under the
1999 Equity Incentive Plan is 2,400,000 shares. A more complete summary of the
primary features of the 1999 Equity Incentive Plan may be found in the section
entitled "Management of the Combined Company -- Impax Laboratories, Inc. 1999
Equity Incentive Plan." The full text of the plan is set forth in Annex G to
this joint proxy statement/prospectus.


     Certain significant shareholders of Impax and Global have entered into a
shareholders' agreement committing these persons to vote their shares for the
next three years for the election as directors of the individuals designated
each year by the members of the current boards of Global and Impax.


     The current members of the board of directors of Global and of Impax, as a
group, also each have the right to designate one observer to the combined
company board of directors.


     The amendment to Global's certificate of incorporation, election of the
named individuals as directors of the combined company, and the adoption of the
new equity incentive plan are conditions to the consummation of the merger.


Stockholders entitled to vote


     The merger cannot be completed without Global stockholder approval.


     The Global board has set November 4, 1999 as the record date to determine
which Global stockholders will be entitled to vote at the special meeting. Only
Global stockholders who hold their shares of record as of the close of business
on November 4, 1999, will be entitled to receive notice of and to vote at the
Global special meeting. On November 4, 1999, there were:


     o  7,254,053 shares of Global common stock outstanding and entitled to vote
        at the Global special meeting, held by approximately 749 stockholders;


     o  9,000 shares of Global Series C preferred stock outstanding and entitled
        to vote at the Global special meeting, held by one stockholder, Small
        Cap Value Portfolio of Bear Stearns & Co., Inc.; and


     o  50,000 shares of Global Series D preferred stock outstanding and
        entitled to vote at the Global special meeting, held by two related
        stockholders, Fleming U.S. Discovery Fund III, L.P. and Fleming U.S.
        Discovery Offshore Fund III, L.P.


                                       31
<PAGE>

Number of shares that must be represented for a vote to be taken


     In order to have a quorum, a majority of the total voting power of the
outstanding shares of Global's capital stock entitled to vote at the Global
special stockholders meeting must be represented in person or by proxy. If a
quorum is not present, a majority of the shares that are represented may
adjourn or postpone the Global special meeting.


Vote required to approve the merger agreement


     Each share of Global common stock is entitled to one vote on each of the
matters being voted on at the Global special meeting. Each share of Global
Series C preferred stock and Series D preferred stock is entitled to 50 votes
on each matter to be voted on. The affirmative vote, either in person or by
proxy, of a majority of the outstanding shares of:

     o  Global common stock, Series C preferred stock and Series D preferred
        stock, voting as one class; and

     o  Global Series D preferred stock, voting as a separate class;

     is required in order to approve the merger agreement.

     These shares may be represented either in person or by proxy. If you
abstain from voting or if you do not submit a proxy card and do not vote in
person at the Global special meeting, your non-action will have the effect of a
vote against the merger. Also, any broker non-vote will have the effect of a
vote against the merger.

     As of the close of business on September 30, 1999, the directors and
executive officers of Global as a group (including the entities with which
these individuals are associated) beneficially owned 5,575,489 shares of Global
common stock, or approximately 55% of the total voting power of the issued and
outstanding shares of Global common stock. These figures are calculated without
counting shares which could be acquired by exercising stock options because the
shares underlying those options cannot be voted at the Global special meeting.
In addition, the entities with which two of these individuals are associated
own 100% of the outstanding shares of Global Series D preferred stock. These
directors and executive officers of Global (and the entities with which they
are associated), including the holders of all of the Series C preferred stock
and Series D preferred stock, have indicated their intention to vote their
shares "FOR" the approval and adoption of the merger agreement.


Voting your shares


     The Global board is soliciting proxies from Global stockholders. This will
give you the opportunity to vote at the Global special meeting. When you
deliver a valid proxy, the shares represented by that proxy will be voted in
accordance with your instructions. If you do not vote by proxy or attend the
Global special meeting and vote in person, it will have the same effect as
voting against the merger.


     You may grant a proxy by signing and mailing your proxy card. You may also
cast your vote in person at the meeting.


     Mail. To grant your proxy by mail, please complete your proxy card, and
sign, date and return it in the enclosed envelope. To be valid, a returned
proxy card must be signed and dated.


     In person. If you attend the Global special meeting in person, you may
vote your shares by completing a ballot at the meeting.


Changing your vote


     You may revoke your proxy at any time before its exercise at the Global
special meeting. You may revoke your proxy by delivering a notice in writing to
the Secretary of Global, granting a later-dated proxy or appearing in person
and voting at the Global special meeting. You will not revoke your proxy by
simply attending the Global special meeting unless you complete a ballot.


                                       32
<PAGE>

How proxies are counted


     If you return a signed and dated proxy card but do not indicate how the
shares are to be voted, those shares represented by your proxy card will be
voted as recommended by the Global board. A valid proxy also gives the
individuals named as proxies authority to vote in their discretion when voting
the shares on any other matters that are properly presented for action at the
Global special meeting. You should be aware that any such properly executed
proxy cards are intended to be voted for approval of the merger proposal,
including of the merger and the matters contemplated by the merger agreement. A
properly executed proxy card marked "abstain" will not be voted. However, it
may be counted to determine whether a quorum is present. A proxy marked
"abstain" will have the effect of a vote against the merger.

     Brokers who hold shares of stock as nominees will not have discretionary
authority to vote these shares in the absence of instructions from the
beneficial owners (sometimes referred to as "broker non-votes"). Broker
non-votes will be counted as present for purposes of determining whether there
is a quorum at the Global special meeting. Therefore, if your shares are held
by a broker or other nominee and you do not give them instructions on how to
vote your shares on the merger, this will have the same effect as voting
against the merger proposal.


Solicitation of proxies and costs


     Proxies for use at the Global special meeting are being solicited by the
Global board of directors. Proxies will be solicited chiefly by mail; however,
certain officers, directors, employees and agents of Global may solicit proxies
by phone or other personal contact. These persons will not receive additional
compensation for conducting this solicitation. Global will bear the cost of the
solicitation of the proxies, including postage, printing and handling.


GLOBAL STOCKHOLDERS SHOULD NOT SEND IN STOCK CERTIFICATES WITH THEIR PROXY
CARDS.

also request that shareholders return their proxy cards by fax. You may also
cast your vote in person at the meeting.

     Mail. To grant your proxy by mail, please complete your proxy card, sign,

                                  THE MERGER


Background of the Merger


Global

     The Global board and management regularly consider Global's strategic
alternatives as part of their ongoing efforts to enhance stockholder value.
These alternatives have included:

     o  seeking additional financing, which would enhance Global's ability to
        develop, commercialize and market its products on an independent basis;

     o  increasing Global's strategy of entering into alliances with other
        pharmaceutical companies for the development of products for Global; and

     o  merging with a strategic partner to gain access to greater scientific,
        technical and development capabilities, as well as financial resources.

     Over the past year, individual directors and management of Global have had
contacts with a number of organizations that were potentially interested in a
strategic combination. These organizations have included both research and
development companies and pharmaceutical firms. None of these discussions moved
beyond the preliminary stage. In May 1998, Barry R. Edwards, President and
Chief Executive Officer of Global, and Charles Hsiao, Chairman of the Board and
Chief Executive Officer of Impax, and Larry Hsu, President of Impax, first met
and held introductory discussions concerning their respective businesses. On
May 13, 1998, Global and Impax entered into a confidentiality agreement in
order to generally explore business opportunities between the companies. These
discussions revolved around a joint-development approach for a select group of
products, half of which would be developed by Global and half by Impax. At
subsequent meetings during June through November 1998, discussions included
Global providing packaging, marketing and distribution services to Impax for
Impax's other products under development in addition to the products being
developed jointly.

     On December 10, 1998, Cornel Spiegler, Chief Financial Officer of Global,
and Mr. Edwards made a presentation to the Global board regarding Global's
alternatives, including a possible business combination with Impax. At that
time, the Global board authorized management to investigate the possibility of
a merger with Impax. Subsequently in December 1998, Global and Impax held
discussions regarding the strategic advantages of a merger.

     In January 1999, Global pursued both financing alternatives that would
permit Global to expand its product development and commercialization
activities and possible strategic combinations. Global reviewed potential
sources of financing, including a private offering of preferred stock. Global
also analyzed a possible strategic combination with Impax and with others.

     On March 2, 1999, Global consummated the first of two tranches of a
private placement of its preferred stock, with gross proceeds to Global of $3
million. The second tranche, which was committed to at that time by the
purchasers (the Flemings funds), required the Global stockholders' to approve
an amendment to Global's certificate of incorporation increasing the authorized
capital stock available to be issued. On May 18, 1999, the second tranche of
the preferred stock sale was consummated, with gross proceeds to Global of $2
million. This financing provided Global with sufficient working capital to give
Global flexibility in its strategic combination discussions.

     On March 4, 1999, Mr. Edwards made a presentation to the Global board
concerning Impax and the possible strategic advantages of a merger of the two
companies. Among the benefits reviewed at the meeting were the additional
research and development capabilities that Impax could provide to Global and
the additional administrative, manufacturing and marketing capabilities that
Global could provide to Impax. The Global board also considered Global's
strategic future as a "stand alone" company, alternatives in light of
conditions in the capital markets, the results of exploratory discussions with
other potential merger partners and the proposed terms of the Impax merger. At
the meeting on March 4, the Global board instructed management to continue
exploratory discussions with Impax and formed a Task Team consisting of
directors


                                       36
<PAGE>

Philip Chapman, George Keane, Udi Toledano and Barry Edwards. Additionally, Mr.
David Edwards of Flemings funds was asked to participate as an observer on the
Task Team (at that time, David Edwards was not yet elected to Global's Board of
Directors). Additional discussions continued between the companies for the next
several weeks, and culminated in Global and Impax executing a Letter of Intent
on March 16, 1999. Detailed business, financial and legal due diligence
commenced immediately. Beginning shortly thereafter, the parties and their
counsel began a series of negotiations over the terms of the merger agreement.


     In addition, the Global board directed management to arrange a meeting
between the members of the merger Task Team and the founders of Impax. The
meeting took place in New York City on March 26, 1999.


     At a meeting held on April 30, 1999, the Global board reviewed the
progress of the due diligence review of Impax. At the meeting, Global's
management made a presentation to the Global board concerning Impax and the
proposed terms of a merger. The Global board directed management to continue in
its review and discussions and to prepare a detailed presentation for the
board.


     On May 7, 1999, a meeting of the Global board was held to review various
aspects of the proposed merger, including detailed forecast and valuation
analyses prepared by management in the course of evaluating the merger with
Impax. The Global board directed management to retain financial advisors to
continue to analyze Impax and the proposed merger, as well as other options
that may be available to Global.


     At a meeting held on May 12, 1999, the Global board again considered its
strategy of remaining an independent company. Based on a variety of factors,
including the expected two-to-three year time horizon for commercialization of
several of Global's key products and conditions in the capital markets, the
Global board concluded that it would be desirable to pursue a combination with
a strategic partner with more significant scientific, technical, and research
and development capabilities. After a further review of the terms of the
proposed Impax merger, as well as Impax's financial resources, research and
development capabilities and success to date in the pharmaceutical industry,
the Global board authorized management and its advisors to pursue a transaction
with Impax. Over the next several months, Global management, the Task Team of
directors and outside advisors continued their due diligence review of Impax
and negotiations regarding specific terms of the merger and the documentation.


     On July 26, 1999, the Global board met to discuss the merger and its
finalized negotiated terms, including the proposed consideration being paid to
Impax shareholders. Representatives of Gruntal and Co., L.L.C. and Global's
legal counsel attended the meeting. At the meeting, Gruntal discussed the
consideration being paid to Impax shareholders and delivered its opinion to the
Global board that the consideration being paid to the Impax shareholders was
fair from a financial point of view to the Global common stockholders. A
detailed review and discussion of the merger documentation ensued, including
the termination and non-solicitation provisions contained in the merger
agreement. These provisions permit the board to consider and, if desirable,
accept an unsolicited superior proposal in the event that one is presented
prior to the closing date of the merger. The Global board also gave specific
consideration to the termination fee contained in the merger agreement. The
Global board then approved the final terms of the merger agreement and
authorized its execution.


Impax


     As part of its business and strategic development, the Impax board and
management continuously evaluates strategic alternatives to further its
development and growth in the industry. These alternatives have included:


     o  seeking additional equity financing to accelerate Impax's development
        and commercialization of products;


     o  seeking debt financing to enable Impax to build its own manufacturing
        facilities;


     o  strategic alliances with other pharmaceutical companies, whereby the
        pharmaceutical companies provide the financing and marketing
        capabilities, and Impax provides the research and development expertise
        and efforts.


                                       37

     During 1996 and 1997, Impax held extensive discussions with another
pharmaceutical company concerning a prospective merger or other combination of
the company. This company was an established manufacturer of pharmaceutical
products. However, the discussions never advanced beyond the preliminary
negotiations and due diligence investigation phase.


     In May 1998, Charles Hsiao, Chairman of the Board and Chief Executive
Officer of Impax, Larry Hsu, President of Impax and Barry R. Edwards, President
and Chief Executive Officer of Global initiated discussions. On May 13, 1998,
Global and Impax entered into a confidentiality agreement to allow the parties
to explore business opportunities. These discussions related to strategic
alliances with respect to joint development of certain products. In November,
1998, Impax discussed the possibility of contracting with Global to provide
packaging, marketing and distribution to Impax for certain Impax proprietary
products.


     In December, 1998, Impax and Global explored the possibility of merging
together, and held numerous discussions regarding the strategic advantages of a
merger and the appropriate exchange ratio.


     In the fourth quarter of 1998, Impax was concurrently pursuing offshore
equity financing to allow Impax to continue to fund its product development
activities and its plans to construct manufacturing facilities. Impax evaluated
various sources of equity financing, with particular focus on potential
synergies between Impax and the prospective investor. In March 1999, Impax
consummated an offshore private placement of its Series D Preferred Stock. In
this financing, Impax raised an aggregate of $17,000,000.


     During March, 1999, Impax had numerous discussions with each of the
individual members of the board of directors, concerning the various aspects of
a prospective merger with Global.


     A board meeting was held on May 3, 1999, in Taipei, Taiwan, at which all
the members of the board of directors were present. Drs. Hsiao and Hsu made
presentations to the Impax Board concerning Global and the potential strategic
advantages of a merger of the two companies. Among the principal benefits
anticipated from Global were the manufacturing and marketing expertise that
Global could provide. Dr. Hsu also presented detailed financial information on
Global, as well as forecasts on the financial results of the combined company.
After a review of the terms of the proposed Impax merger, as well as Global's
financial resources, its manufacturing and marketing capabilities, the Impax
board authorized management and its advisors to pursue a transaction with
Global. Over the next several months, Impax management and its advisors
continued their due diligence review of Global and negotiations regarding
specific terms of the merger.


     On or about July 2, 1999, the merger agreement was delivered to each of
the members of the Impax board of directors. From June 30, 1999, through July
13, 1999, Dr. Hsu held individual meetings with each of the members of the
Board, either in person or by telephone. In each of these meetings, Dr. Hsu
reviewed the terms of the proposed merger, the fairness of the exchange ratio,
and lengthy discussions followed.


     On July 25, 1999, the Impax board of directors, via unanimous written
consent, approved the merger agreement and the related transactions.


Joint Reasons for the Merger


     The directors and management of Global and Impax believe that the merger
will create a stronger competitor and will provide significant value for the
shareholders of Impax and Global for, among other things, the following
reasons:


     The merger brings together a complementary blend of assets and
capabilities.


     o  Global will realize significant enhancement to its generic product
        pipeline via Impax's extensive projects, and Impax will have access to
        Global's well-established generic product sales and marketing team.


     o  The combination of marketing and product development expertise in the
        same company will lead to better strategic planning in product
        development.


                                       38
<PAGE>

     o  The merger enables both companies to accelerate execution of their
        strategies through added financial reserves and enhanced borrowing
        capabilities.


     o  The management and directors of Global and Impax believe that the merger
        will result in significant opportunities for cost savings, revenue
        growth, technological development and other benefits. The combined
        company is expected to achieve synergies through economies of scope and
        scale and the elimination of duplicative expenditures.


Global Board of Directors' Consideration and Approval of the Merger


     In reaching its conclusion to approve the merger agreement, the Global
board consulted with management of Global, as well as its financial and legal
advisors and considered a number of factors in addition to those explained in
the section discussing the reasons for the merger, including the following:


     1. The importance of the merger in implementing and accelerating Global's
        basic long-term growth strategy in light of the current economic,
        financial and business environment.


     2. Global's financial condition, results of operations, business and
        prospects, as compared to those of the combined company's. In
        considering this financial information, the Global board took into
        account Global's and Impax's recent and historic valuations and earnings
        performances, as well as an analysis of the business opportunities
        presented by the merger. The Global board considered detailed financial
        analyses and pro forma and other financial data presented by Gruntal, in
        addition to the business of Global and Impax and the industries in which
        they operate.


     3. The terms of the merger agreement, as well as other information
        concerning the merger, including the terms and structure of the merger.
        Among other things, the board considered the expectation that the merger
        will be treated as a tax-free transaction for U.S. federal income tax
        purposes to Global stockholders and will be accounted for using purchase
        accounting.


     4. Impax's access to capital to finance research and development which
        would enable the combined company to pursue more product development and
        license products to others at a later stage in development, thereby
        increasing its share of profits.


     5. Global's access to Impax's research and development expertise which,
        Global believes, can be leveraged to broaden its product line.


     6. The benefit to achieving economies of scale, because the pharmaceutical
        industry is characterized by intense competition and consolidation.


     7. The advantages and potential disadvantages of the merger structure,
        including the sharing of board of director seats and senior management
        positions in the combined company between people from the two companies
        and the use of a co-CEO structure;


     8. The other potential major transactions which might be available to
        Global either in addition to, or as alternatives to, the merger, and the
        effect of the merger in making it easier or harder to pursue those
        transactions; and


     9. The difficulty of integrating the business of Global and Impax, and the
        possible adverse effects that could result from the need for senior
        management to focus significant time and effort on completing the merger
        and integrating the business.


    10. The effect on Global stockholders of Global continuing as a stand-alone
        entity compared to the effect of Global combining with Impax, in light
        of the factors summarized above.


                                       39
<PAGE>

     The Global board also considered a number of potential risks and
disadvantages relating to the merger, including:

     1. the difficulty and management distraction inherent in integrating two
        businesses;

     2. risks relating to the disparate nature of Global's and Impax's core
        businesses;

     3. the risk that the merger would not be consummated;

     4. the one-time charge that will be incurred in connection with the Merger;

     5. the majority stock position to be held post-merger by the Impax
        shareholders;

     6. the dilution to the existing stockholders of Global; and

     7. the uncertainty regarding stockholders', customers', suppliers' and
        employees' perceptions of the merger.

Please refer to "Risk Factors" earlier in this joint proxy statement/prospectus
commencing on page 15.

     The Global board believed that these risks were outweighed by the
potential benefits to be realized from the merger. The foregoing discussion of
the information and factors considered by the Global board is not intended to
be exhaustive but is believed to include all material factors considered by the
Global board in approving the merger. In view of the wide variety of
information and factors considered, the Global board did not find it practical
to, and did not, assign any relative or specific weights to the foregoing
factors and individual directors may have given differing weights to different
factors.


Information and Factors Considered by the Impax Board of Directors


     In deciding whether to approve the merger, and the merger agreement, the
Impax board of directors considered a number of factors in addition to those
explained in the section discussing the reasons for the merger. The following
summarizes the other material information and factors that the Impax board of
directors considered:

     1. Important consideration about Impax, Global and the proposed combined
company including:

        o  the financial condition, results of operations, cash flows and
           prospects of Impax, Global and the combined company;

        o  the expectation that the combined company will produce greater
           stockholder returns than either Impax or Global could produce on its
           own;

        o  the belief that the combined company will produce earnings growth at
           or above the high end of Impax's current projected range, and will
           increase the ability to sustain these earnings by producing
           significant synergies; and

        o  the strategic fit of Impax and Global, including the potential
           synergies resulting from the combinations of marketing and product
           development expertise in the same company and the impact of those
           synergies on the ability of the combined company to compete in the
           industry.

     2. The proposed structure of the transaction and the other terms of the
        merger agreement including the following:

        o  the representations and warranties of the parties;

        o  the covenants of the parties and the effect of those provisions on
           the operations of Impax and Global prior to the merger;

        o  the requirement that Impax and Global must pay the other (1) its
           expenses incurred in connection with the merger, up to $500,000, and
           (2) a termination fee of $500,000 if the merger agreement is
           terminated after the board of directors changes its recommendation
           and the stockholders of that company fail to approve the merger.


                                       40
<PAGE>

     3. The financial presentations and the analysis of the special project
        report presented by Dr. Hsu at the Impax board meeting on May 5, 1999;

     4. The impact of the merger on Impax's shareholders and employees;

     5. The dollar amount of synergies which the which the combined company
        should be able to realize, and the risks that the synergies would not
        all be realized;

     6. The financial implications of not being able to account for the
        transaction as a "pooling of interest";

     7. The advantages and potential disadvantages of the merger structure,
        including the sharing of board of director seats and senior management
        positions in the combined company between people from the two companies
        and the use of a co-CEO structure;

     8. The other potential major transactions which might be available to Impax
        either in addition to, or as alternatives to, the merger, and the effect
        of the merger in making it easier or harder to pursue those
        transactions; and

     9. The difficulty of integrating the business of Global and Impax, and the
        possible adverse effects that could result from the need for senior
        management to focus significant time and effort on completing the merger
        and integrating the business.

     In addition to these factors, the Impax board of directors also considered
the potential adverse impact of other factors on the proposed merger. These
included:

     o  the challenges in combining the assets and workforces of two companies;

     o  the ability of the combined company's management to continue to focus on
        strategic goals while working to implement the merger; and

     o  the risk that the proposed merger would not be consummated.

     The Impax board of directors did not assign particular weight or ranking
to any of the factors it considered in approving the merger. Also, in making
their determination, it is possible that individual directors may have assigned
a different level of importance to each factor.

     The Impax board of directors unanimously recommends that Impax
shareholders vote FOR the Impax merger proposal.


Opinion of Global's Financial Advisor

     Gruntal was retained by Global to provide a fairness opinion in connection
with the merger based upon Gruntal's experience and expertise. At the July 26,
1999 meeting of Global's board, Gruntal rendered to the board its oral opinion,
confirmed in writing as of the same date, that based upon and subject to the
matters stated in the opinion, as of July 26, 1999, the Global common stock and
the Global Series 1 preferred stock to be issued to the shareholders of Impax
in connection with the merger is fair, from a financial point of view, to the
holders of Global common stock. Gruntal subsequently affirmed its earlier
opinion in writing on November 8, 1999.

     The full text of Gruntal's opinion dated July 26, 1999, which sets forth
the assumptions made, matters considered and limitations on the review
undertaken is attached as Annex B to this document and is incorporated in this
summary by reference. Global stockholders should read Gruntal's opinion
carefully in its entirety. Gruntal's opinion is directed to Global's board and
the fairness of the consideration issued to the shareholders of Impax in
connection with the merger from a financial point of view to Global's common
stockholders, and does not address any other aspect of the merger nor does it
constitute a recommendation to any Global stockholder as to how to vote at the
Global special meeting. The summary of Gruntal's opinion set forth in this
document is qualified in its entirety by reference to the full text of the
opinion.


                                       41
<PAGE>

   In arriving at its opinion, Gruntal:

     o  reviewed a draft of the merger agreement dated July 20, 1999 and, for
        purposes of its opinion, assumed that the final form thereof would not
        differ in any material respect from such draft;

     o  held discussions with members of senior management of Global and Impax
        regarding their respective past and current business operations and
        their financial conditions and future prospects;

     o  reviewed historical financial and business information provided to them
        by the management of Global and the management of Impax;

     o  reviewed internally prepared financial projections of Global and Impax
        furnished to them by the management of Global and the management of
        Impax;


     o  reviewed the historical stock prices and trading volumes of Global
        common stock;

     o  reviewed certain historical financial and operating data of public
        companies whose business Gruntal considered comparable to that of each
        of Global and Impax;

     o  reviewed the financial terms, to the extent publicly available, of
        certain transactions which Gruntal considered comparable to the
        contemplated merger;

     o  performed discounted cash flow analyses of Global and Impax based upon
        certain assumptions of future performance provided by management of
        Global and management of Impax; and

     o  conducted such other analyses and reviewed such other information as
        Gruntal deemed appropriate.

     In the course of its review, Gruntal relied upon and assumed the accuracy
and completeness of all the financial and other information furnished to it by
Global and Impax and their respective representatives and did not attempt to
verify that information. Gruntal did not make or obtain any independent
evaluations or appraisals of the assets or liabilities of Impax or Global,
including, but not limited to, liabilities arising from or connected with any
pending or future litigation to which Global or Impax was or may become a
party. With respect to the financial projections furnished to Gruntal or
discussed by Gruntal with the management of Global and Impax, Gruntal assumed
that they had been reasonably prepared and reflect the best currently available
estimates and judgment of Global's and Impax's management as to the expected
future results of operations, synergies and financial condition of Global and
Impax to which such analyses and forecasts relate, and Gruntal assumed that
such expected future results of operations, synergies and strategic benefits
would be realized in the amounts and time periods as described by such
management and for purposes of one or more of its analyses, or part of its
analysis, may have made certain modifications to that information as discussed
in the conclusion of this section on page 48. Global's and Impax's financial
projections are each highly dependent on the outcome of clinical trials, market
acceptance of untested products, including pharmaceutical products and drug
delivery systems, and the efforts of corporate partners. The inability of
Global and Impax to realize such expected future results of operations,
synergies and strategic benefits could affect Gruntal's opinion, and Gruntal
expressed no view as to whether such future results of operations, synergies
and strategic benefits would actually be realized. Gruntal also assumed that
the transaction would have the tax consequences described in the merger
agreement and in discussions with, and other materials furnished to Gruntal by,
representatives of Global. In addition, Gruntal noted that Global expects to
pay no income taxes for the next several years due to an approximately $20
million net operating loss carry forward.

     Gruntal's opinion was necessarily based on economic, market and other
conditions as in effect on, and the information made available to it as of,
July 26, 1999. It should be understood that subsequent developments including,
without limitation, any changes to the terms or conditions of the contemplated
merger, may affect its opinion and that Gruntal does not have any obligation to
update or revise its opinion, other than to provide a letter with respect to
affirming its opinion. Gruntal expressed no opinion on the price at which
Global common stock or the Global series 1 preferred stock would trade at any
future date. Gruntal also assumed that in the course of obtaining the necessary
regulatory or other consents or approvals, contractual or otherwise, for the
contemplated merger, no material restrictions, including any divestiture
requirements or amendments or modifications to, the contemplated merger would
be imposed.

                                       42
<PAGE>

     Gruntal's opinion did not address the merits of the underlying business
decision by Global to engage in the merger. Gruntal expressed no opinion as to
the prices at which Global or Impax shares would trade following the
announcement or, in the case of the Impax shares, consummation of the merger.


     The following is a summary of the material financial analyses performed by
Gruntal in arriving at its opinion. Certain of the financial analyses performed
by Gruntal were deemed by Gruntal to be more material to its analysis and
others were determined to be less material or not meaningful to its analysis
and, therefore, may not have been relied on to issue its opinion.


  Valuation of Global


     In consideration of the fact that the merger requires the issuance of
Global's common stock, Gruntal conducted a variety of analyses to determine
that the range of potential market values of the Global common stock to be
issued in connection with the merger appropriately reflects the stock's implied
value. Gruntal performed two primary valuation analyses of Global:


     (i)  Discounted Cash Flow Analysis: This analysis consists of adding the
          discounted present value of the projected future free cash flows of
          Global from January 1, 2000 to December 31, 2003 and the discounted
          present value of the terminal value of Global, based on a multiple of
          net income projected for the year ending December 31, 2003;


     (ii) Comparable Company Analysis: This analysis is a comparison of Global
          with certain generic pharmaceuticals companies, which are publicly
          traded companies in the generic pharmaceuticals industry and are
          specified below, which analysis consisted of reviewing and considering
          certain financial and market data for the generic pharmaceuticals
          companies.


     Global Discounted Cash Flow Analysis


     Gruntal performed a discounted cash flow analysis, based on the financial
projections provided by Global's management. Global's projections were modified
by Gruntal to reflect a more conservative approach towards the future
operations of Global.


     A range of values for Global's equity was determined by the following
discounted cash flow method: calculating the present value of Global's
estimated future free cash flows from January 1, 2000 to December 31, 2003, and
adding to such amount the present value of Global's terminal value obtained by
capitalizing Global's projected net income for the year ending December 31,
2003 at multiples of 14x, 16x, 18x and 20x. The range of the terminal value
multiples used for Global was based on the range of multiples of net income at
which certain generic pharmaceuticals companies selected by Gruntal are
expected to trade over the long term.


     Gruntal applied discount rates of 30.0%, 35.0% and 40.0% to calculate the
present value of Global's estimated future free cash flows from January 1, 2000
to December 31, 2003 and the terminal value calculated based on the above
multiples of Global's 2003 projected net income. This range of discount rates
was derived using certain assumptions as to the risk associated with
achievement of the modified Global management projections.


     The range of present values derived for Global's equity by applying the
discounted cash flow analysis based upon the modified Global management
projections was $27.8 million ($2.69 per share) to $49.9 million ($4.83 per
share), with an average value of $37.9 million ($3.66 per share).

     Global Comparable Company Analysis

     Gruntal analyzed eleven generic pharmaceutical companies to evaluate the
market and aggregate values at which these companies trade relative to their
respective historical and projected financial performance. The generic
pharmaceutical companies used in the Global Comparable Company Analysis, whose
business, industry, products or operations Gruntal considered to be comparable
to Global in one or more respects, consisted of the following companies:


                          Global Comparable Companies


  o Alpharma Inc.                            o IVAX Corporation
  o Barr Laboratories                        o Lannett Company
  o Copley Pharmaceutical, Inc.              o Mylan Laboratories Inc.
  o Duramed Pharmaceuticals, Inc.            o Warner Chilcott Laboratories
  o Halsey Drug Company                      o Watson Pharmaceuticals, Inc.
  o Hi-Tech Pharmacal Co.


     Gruntal analyzed, among other things, the market values and certain other
financial data for the generic pharmaceutical companies, including their
revenue, earnings before interest and taxes (which is commonly referred to as
EBIT), earnings before interest, taxes, depreciation and amortization (which is
commonly referred to as EBITDA) and earnings per share, in each case, for the
most recent twelve month period for which information was available and on an
estimated basis for 2000 and 2001. The estimates for the generic pharmaceutical
companies were taken from I/B/E/S International Inc., a well-known aggregator
of financial data from publicly available research reports published by a
variety of investment firms and research analysts. The average values,
excluding any outliers, for market value of common equity on July 22, 1999 plus
total long-term debt and preferred stock less cash, or enterprise value, as a
multiple of each of the indicated statistics for the generic pharmaceutical
companies, were as follows:

     (i)  Twelve Months Ended 3/31/99 revenue:                          3.1x
     (ii) Twelve Months Ended 3/31/99 EBIT:                            13.3x

     The average values, excluding any outliers, for market value of treasury
method diluted common equity on July 22, 1999 as a multiple of earnings per
share for the following periods for the generic pharmaceuticals companies were
as follows:

     (i)   Twelve months ended 3/31/99 earnings per share or EPS:      20.6x
     (ii)  2000 EPS:                                                   20.4x
     (iii) 2001 EPS:                                                   17.4x

     Applying these multiples to Global's twelve months ended March 31, 1999
results and to the modified Global management projections yielded implied
equity values for Global ranging from $15.3 million ($1.48 per share) to $96.0
million ($9.28 per share), with an average of $56.6 million ($5.47 per share).


  Valuation of Impax


     In rendering its opinion, Gruntal, among other things, performed three
primary valuation analyses of Impax:

     (i)   Discounted Cash Flow Analysis: This analysis consists of adding the
           discounted present value of the projected future free cash flows of
           Impax from January 1, 2000 to December 31, 2003 and the discounted
           present value of the terminal value of Impax, based on a multiple of
           net income projected for the year ending December 31, 2003;


     (ii)  Comparable Company Analysis: This analysis is a comparison of Impax
           with certain publicly traded companies in the drug delivery industry,
           which are specified below, and which analysis consisted of reviewing
           and considering certain financial and market data for the drug
           delivery companies selected by Gruntal; and


                                       44
<PAGE>

     (iii) Comparable Merger and Acquisition Transactions Analysis: This
           analysis is a comparison of the multiples paid in certain merger and
           acquisition transactions involving companies in the drug delivery and
           generic and specialty pharmaceuticals industry.

     Impax Discounted Cash Flow Analysis

     Gruntal performed a discounted cash flow analysis, based on the financial
projections provided by Impax's management. The Impax management's projections
were modified by Gruntal to reflect a more conservative approach towards the
future operations of Impax. In the long run, Impax's financial projections are
highly dependent on the outcome of clinical trials, market acceptance of
untested products and the efforts of corporate partners.

     The implied value of Impax's equity was determined by the following
discounted cash flow method: calculating the present value of Impax's estimated
future free cash flows from January 1, 2000 to December 31, 2003, and adding to
such amount the present value of Impax's terminal value obtained by
capitalizing Impax's projected net income for the year ending December 31, 2003
at multiples of 20x, 22x, 24x and 26x. The range of terminal value multiples
applied to Impax was based on the range of multiples of net income at which
certain drug delivery companies selected by Gruntal are expected to trade over
the long term.

     Gruntal applied discount rates of 40.0%, 45.0% and 50.0% to calculate the
present value of Impax's estimated future free cash flows from January 1, 2000
to December 31, 2003 and the terminal value based on a multiple of Impax's 2003
projected net income. This range of discount rates was derived using certain
assumptions as to the risk associated with achievement of the modified Impax
management projections.

     The range of present values derived for Impax's equity by applying the
discounted cash flow analysis based upon the modified Impax management
projections was $180.8 million ($19.93 per share) to $314.1 million ($34.62 per
share), with an average value of $242.1 million ($26.70 per share).

     Impax Comparable Company Analysis

     Gruntal analyzed ten drug delivery companies that it selected to evaluate
the market and aggregate values at which these companies trade relative to
their respective historical and projected financial performance. The drug
delivery companies used in the Impax Comparable Company Analysis, whose
business, industry, products or operations Gruntal considered to be comparable
to Impax in one or more respects, consisted of the following companies:


<TABLE>
<S>                                             <C>
         o Andrx Corporation                    o Emisphere Technologies, Inc.
         o Biovail Corporation International    o Fuisz Technologies Ltd.
         o CIMA Labs Inc.                       o Kos Pharmaceuticals, Inc.
         o Cygnus, Inc.                         o K-V Pharmaceutical Company
         o Elan Corporation PLC                 o Matrix Pharmaceutical, Inc.

</TABLE>

     Gruntal analyzed, among other things, the market values and certain
financial criteria for the drug delivery companies, including their revenue,
earnings before interest and taxes, or EBIT, and earnings per share, in each
case, for the most recent twelve month period for which information was
available and on an estimated basis for 2000 and 2001. Such estimates for the
drug delivery companies were taken from I/B/E/S International Inc., a
well-known aggregator of financial data from publicly available research
reports published by a variety of investment firms and research analysts. The
average values, excluding any outliers, for market value of common equity on
July 22, 1999 plus total long-term debt and preferred stock less cash, or
enterprise value, as a multiple of each of the indicated statistics for the
drug delivery companies were as follows:

     (i)  Latest twelve months ended revenue:                           7.5x
     (ii) Projected 2001 revenue:                                       4.1x

     The average values, excluding any outliers, for market value of treasury
method diluted common equity on July 22, 1999 as a multiple of earnings per
share for the following periods for the drug delivery companies were as
follows:

     (i)   Twelve months ended 3/31/99 EPS:                            25.7x
     (ii)  2000 EPS                                                    16.7x
     (iii) 2001 EPS                                                    13.5x

                                       45
<PAGE>

     Applying these multiples to Impax's twelve months ended March 31, 1999
results and the modified Impax management projections yielded implied equity
values for Impax ranging from $30.0 million ($3.31 per share) to $340.3 million
($37.51 per share), with an average of $207.1 million ($22.83 per share). Due
to the early stage of development of Impax, Gruntal applied the relevant latest
twelve month multiples to future Impax earnings and revenue, as projected in
the modified Impax management projections, to obtain projected enterprise and
equity values of Impax in the future. Gruntal then discounted these values to
the present using a 45% discount rate. Such values are included in the range
and average values above.


Impax Comparable Merger and Acquisition Transactions Analysis


     Gruntal reviewed the consideration paid in certain merger and acquisition
transactions involving drug delivery and generic and specialty pharmaceuticals
companies. The transactions which Gruntal reviewed consisted of the
acquisitions or pending acquisitions, listed in the following table:


                    Drug Delivery and Generic and Specialty
                       Pharmaceuticals M&A Transactions

       Pending        ALZA Corp.                     Abbott Laboratories

</TABLE>

     Gruntal also calculated multiples for each transaction based on the ratio
of the equity value of the transaction to the acquired companies' respective
net income for the most recent twelve month period for which data was available
prior to such transaction and the ratio of the equity value of the transaction
plus total debt and preferred stock less cash, which is commonly referred to as
enterprise value, to the acquired companies' pre-acquisition last twelve months
ended revenue and latest twelve months ended EBIT. The high, low, average and
median equity value of the transaction multiples of last twelve months ended
net income for the drug delivery and generic and specialty pharmaceuticals
merger and acquisition transactions, which are specified above, were 50.2x,
45.3x, 47.8x and 47.8x respectively. The high, low, average and median values
of the ratio of the equity value of the transaction plus total debt and
preferred stock less cash, or enterprise value, as a multiple of each of the
indicated statistics for the drug delivery and generic and specialty
pharmaceuticals merger and acquisition transactions were as follows:


         (a) Twelve months revenue: 10.5x, 6.4x, 9.2x and 9.9x;
         (b) Twelve months EBIT: 42.3x, 30.1x, 36.2x and 36.2x.


     Applying the average multiples to Impax's results for the twelve months
ended March 31, 1999 and projected results yielded implied equity values of
Impax ranging from $50.7 million ($5.58 per share) to $683.5 million ($75.33
per share) and an average value of Impax's equity of $328.9 million ($36.25 per
share). Due to the early stage of development of Impax, Gruntal applied the
relevant twelve months ended March 31, 1999 multiples to future Impax earnings,
revenue and EBIT as projected in the modified Impax management projections, to
obtain projected enterprise and equity values of Impax in the future. Gruntal
then discounted these values to the present using a 45% discount rate. Such
values are included in the range and average values above.

Valuation of Combined Company

     Gruntal conducted a valuation of the pro-forma combined company to depict
the potential value accretion to Global's stockholders. Gruntal performed two
primary valuation analyses of the combined company. Both of these analyses were
performed on the combined company without synergies and the combined company
with synergies, as provided by Global's and Impax's management and modified by
Gruntal.

     (i)  Discounted Cash Flow Analysis: This analysis consists of adding the
          discounted present value of the projected future free cash flows of
          the combined company from January 1, 2000 to December 31, 2003 and
          the discounted present value of the terminal value of Global, based
          on a multiple of net income projected for the year ending December
          31, 2003;

     (ii) Comparable Company Analysis: This analysis is a comparison of the
          combined company with certain drug delivery companies, which are the
          same publicly traded companies used in the Impax comparable company
          analysis.

     Combined Company Discounted Cash Flow Analysis

     Gruntal performed a discounted cash flow analysis, based on the financial
projections of Impax and Global and anticipated synergies as provided by
Global's and Impax's management. The synergies were modified by Gruntal to
reflect a more conservative approach towards the future operations of the
combined company.

     An implied value of the combined company's equity was determined by the
following discounted cash flow method: calculating the present value of the
combined company's estimated future free cash flows, with and without
synergies, from January 1, 2000 to December 31, 2003, and adding to such
amounts the present value of the combined company's terminal value obtained by
capitalizing the combined company's projected net income, with and without
synergies, for the year ending December 31, 2003 at multiples of 20x, 22x, 24x
and 26x. The range of the terminal value multiples used for the combined
company was based on the range of multiples of net income at which certain drug
delivery companies selected by Gruntal are expected to trade over the long
term.

     Gruntal applied discount rates of 40.0%, 45.0% and 50.0% to calculate the
present value of the combined company's estimated future free cash flows, with
and without synergies, from January 1, 2000 to December 31, 2003 and the
terminal value calculated based on a multiple of the combined company's 2003
projected net income, with and without synergies.


     The range of present values derived for the combined company's equity by
applying the discounted cash flow analysis based upon the combined company's
projections without synergies was $197.7 million ($4.72 per share) to $342.1
million ($8.16 per share), with an average value of $264.1 million ($6.30 per
share).


     The range of present values derived for the combined company's equity by
applying the discounted cash flow analysis based upon the combined company's
projections including management provided synergies, as modified by Gruntal,
was $291.6 million ($6.96 per share) to $497.0 million ($11.86 per share), with
an average value of $386.0 million ($9.21 per share).


     Combined Company Comparable Company Analysis


     This analysis was based on the financial and market data derived from the
Impax Comparable Company Analysis.


     The data derived in the Impax Comparable Company Analysis yielded implied
equity values for the combined company without synergies ranging from $77.1
million ($1.84 per share) to $352.8 million ($7.77 per share), with an average
of $251.6 million ($6.00 per share).


     The data derived in the Impax Comparable Company Analysis yielded implied
equity values for the combined company including management provided synergies,
as modified by Gruntal, ranging from $189.3 million ($4.52 per share) to $417.6
million ($9.96 per share), with an average of $345.8 million ($8.25 per share).



                                       47
<PAGE>

     Gruntal applied the relevant latest twelve month multiples to the future
combined company earnings and revenues, in both cases above, to obtain
projected enterprise and equity values of the combined company in the future.
Gruntal then discounted these values to the present using a 45% discount rate.
Such values are included in the range and average values above.


Other Analysis


     Historical Trading: Gruntal reviewed current and historical market closing
prices and trading data of Global's common stock over the past year. Gruntal
noted that over the 52 weeks ended July 22, 1999, the high trading price was
$3.9375, the low trading price was $1.00 and the average trading price was
$2.485.


     Contribution Analysis: Gruntal compared the relative contributions of both
Global and Impax to the pro-forma combined company net income, without
accounting for any synergies. The contribution analysis, based on the modified
Impax management projections and the modified Global management projections
indicated the following:




                                           Global's contribution % of
                                           ---------------------------
                                            Revenue     Pre-Tax Income

Projected year ended December 31, 2000     96.0%            NM(1)
Projected year ended December 31, 2001     62.5%       71.2%
Projected year ended December 31, 2002     21.1%       11.2%
Projected year ended December 31, 2003     15.8%        6.8%

- ------------
(1) Pre-tax income is projected to be negative for the year ended December 31,
2000.


     EPS Accretion/Dilution Analysis: In using the modified Impax management
projections and the modified Global management projections, Gruntal determined
that, excluding and including modified management provided synergies, the
merger will be dilutive to Global's earnings per share in years ended December
31, 2000 and 2001, and accretive in the year ended December 31, 2002.


Conclusion


     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. The
foregoing summary does not purport to be a complete description of the analyses
performed by Gruntal. In arriving at its opinion, Gruntal considered the
results of all of its analyses as a whole and did not attribute any particular
weight to any particular analysis or factor considered by it, but rather made
qualitative judgments as to the significance and relevance of each analysis and
factor. Furthermore, selecting any portion of Gruntal's analyses, without
considering all analyses, would create an incomplete view of the process
underlying Gruntal's opinion, and could result in an incorrect conclusion. In
addition, Gruntal may have deemed various assumptions more or less probable
than other assumptions, so that the ranges of valuations resulting for any
particular analysis described above should not be taken to be Gruntal's view of
the actual value of Global common stock or preferred stock, Impax common stock
or preferred stock, or common stock or preferred stock of the combined company.



     No transaction utilized in the comparable transaction analysis is
identical to the merger, and no company utilized in the comparable companies
analysis is identical to Global. In evaluating the precedent transactions and
the selected comparable companies, Gruntal made judgments and assumptions with
regard to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Global, such as the impact of competition on the business of Global and the
industry generally, industry growth and the absence of any adverse material
change in the financial condition and prospects of Impax or the industry or in
the financial markets in general. In addition, to prepare its analyses, Gruntal
may have made certain risk adjustments. Gruntal considered and may have made
certain modifications to information provided to it from Global, Impax or both
of them, such as:


                                       48
<PAGE>

   o modifying the projected impact and/or timing of certain drugs or drug
     delivery systems, or removing them altogether from consideration,


   o using higher discount rates than projected by Global, Impax or both of
     them in conducting its analyses, to evaluate the present value of earnings
     projected by Global and Impax,


   o comparing the Global and Impax margins to the margins of comparable
     companies in the same industry and increasing certain expenses above
     management expectations, such as research and development expenses.


     In performing its analyses, Gruntal made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond the control of Global. The analyses performed
by Gruntal are not necessarily indicative of actual values, which may be
significantly more or less favorable than suggested by these analyses. These
analyses were prepared solely as a part of Gruntal's analysis of the fairness
of the Global common stock and the Global Series 1 preferred stock issued in
the merger, from a financial point of view to holders of Global common stock
and were provided to Global's board in connection with the delivery of
Gruntal's opinion. The analyses do not purport to be appraisals or to reflect
the prices at which Global might actually be sold. In addition, as described
above, Gruntal's opinion, including Gruntal's presentation to Global's board,
was one of many factors taken into consideration by Global's board in making
its determination to approve the merger. Consequently, the Gruntal analyses
described above should not be viewed as determinative of the opinion of
Global's board or the view of the management of Global with respect to the
value of Global common stock or the Series 1 preferred stock or of whether
Global's board would have been willing to agree to a different exchange ratio.
The common stock and the Global Series 1 preferred stock to be issued to the
shareholders of Impax was determined through arm's length negotiations between
Global and Impax and was approved by Global's board. The decision to enter into
the merger agreement and to accept the exchange ratio was solely that of
Global's board.


     Global's board retained Gruntal based upon Gruntal's experience and
expertise. Gruntal is a nationally recognized investment banking and financial
advisory firm. Gruntal, as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
distributions of listed and unlisted securities, private placements and
financial valuations for corporate purposes. In addition, in the ordinary
course of its business, Gruntal may actively trade Global common stock for
Gruntal's account and for the accounts of customers, and accordingly, may at
any time hold a long or short position in such security.


     Pursuant to a letter agreement dated May 17, 1999, Global has agreed to
pay Gruntal a fee of $125,000, which is comprised of $50,000 payable to Gruntal
upon execution of the letter agreement and $75,000 payable to Gruntal at the
time Gruntal delivered its opinion. Global has also agreed to reimburse Gruntal
for its out-of-pocket expenses, including fees and disbursements of counsel.
Global must give its consent for expenses in excess of $12,500. The merger
agreement provides that Gruntal will have delivered a letter within two days of
this joint proxy statement/prospectus with respect to its affirmation of its
opinion. Global has agreed to pay Gruntal an additional $25,000 for doing so.
In the event the merger is not consummated within six months after the letter
agreement, Gruntal may receive an advisory fee equal to an additional amount,
to be mutually agreed upon between Global and Gruntal. In addition to the
foregoing compensation, Global has agreed to indemnify Gruntal for certain
liabilities and expenses arising out of the engagement and the transactions in
connection with the engagement, including certain liabilities under U.S.
federal securities laws.


Anticipated Accounting Treatment


     In the proposed transaction, Global will be acquiring all of the
outstanding shares of Impax stock and the combination will be accounted for
under the purchase method of accounting. However, for financial accounting
purposes the transaction will be accounted for as a "reverse acquisition" and
Impax's historical financial statements will be the financial statements of the
post-merger combined company. Under the purchase method of accounting, Global's
results of operations will be combined with those of Impax from and


                                       49
<PAGE>

after the acquisition date, and Global's specific tangible and identifiable
intangible assets and liabilities will be recorded in Impax's financial
statements at their respective fair values at the acquisition date. The excess
of the purchase price over the fair value of Global's specific tangible and
identifiable intangible assets and liabilities will be recorded as goodwill and
amortized over a period not expected to exceed ten years.


Material Federal Income Tax Consequences


     The following general discussion summarizes the material U.S. federal
income tax consequences of the merger. The following discussion is based on the
Internal Revenue Code of 1986, as amended, the regulations promulgated
thereunder, existing administrative interpretations and court decisions, all of
which are subject to change, possibly with retroactive effect, and assumes that
the merger will be consummated in the manner described in this joint proxy
statement/prospectus and in accordance with the merger agreement (without
amendment). This discussion does not address all aspects of federal income
taxation that may be important to a stockholder in light of the stockholder's
particular circumstances. It also does not apply to those stockholders subject
to special rules, such as stockholders who are not citizens or residents of the
United States, financial institutions, tax-exempt organizations, insurance
companies, dealers in securities, stockholders who acquired their Impax common
stock pursuant to the exercise of options or similar derivative securities or
otherwise as compensation or stockholders who hold their Impax shares as part
of a straddle or conversion transaction. This discussion assumes that Impax
shareholders hold their respective shares of stock as capital assets within the
meaning of Section 1221 of the Internal Revenue Code.


     It is the opinion of Fulbright & Jaworski L.L.P., counsel to Global, that
the merger will qualify as a reorganization within the meaning of section
368(a) of the Internal Revenue Code. This opinion regarding the qualification
of the merger as a reorganization is based upon, among other things,
certificates provided by officers of Global and Impax relating to various
technical requirements of the Code. Opinions of counsel are not binding on the
Internal Revenue Service or the courts. The Internal Revenue Service might not
agree with these opinions or with the discussion contained in this section, and
it could challenge the tax treatment of the merger. Assuming the merger
qualifies as a reorganization for federal income tax purposes, the merger will
have the following federal income tax consequences:


     (a) Tax Consequences to Global Stockholders. Current holders of Global
common stock will not recognize any gain or loss for federal income tax
purposes as a result of the merger.


     Current holders of Global Series C preferred stock whose stock is
converted into combined company common stock in the merger, and holders of
Global Series D preferred stock whose stock is converted into combined company
Series 1-A preferred stock in the merger, will not recognize gain or loss for
federal income tax purposes. The aggregate tax basis of combined company stock
which a holder receives as a result of the merger will be the same as his
aggregate tax basis in the Global preferred stock which is converted in the
merger. Also, the holding period for the combined company stock which the
preferred stockholder receives in the merger will include the period during
which he held his Global preferred stock.


     (b) Tax Consequences to Impax Shareholders. Holders of Impax common stock,
Series A preferred stock, Series B preferred stock and Series C preferred stock
whose stock is converted into combined company common stock in the merger will
not recognize gain or loss for federal income tax purposes, except to the
extent that they receive cash instead of a fractional share. Holders of Impax
Series D preferred stock, whose Impax stock is converted into combined company
Series 1-B preferred stock in the merger, should not recognize gain for federal
income tax purposes, except to the extent they receive cash instead of a
fraction of a share. Counsel to Global believes that the Series 1-B preferred
stock should not be treated as "nonqualified preferred stock," and therefore
should be received by Impax Series D preferred shareholders without recognition
of gain. However, in 1997, Congress made changes to the Code which cause
recipients of preferred stock which is treated as "nonqualified preferred
stock" to recognize gain on the receipt of "nonqualified preferred stock" in a
tax-free reorganization, to the extent that the value of "nonqualified
preferred stock" received exceeds the basis of stock surrendered. "Nonqualified
preferred stock" is preferred stock which either the holder can require the
issuer to redeem, the issuer is required to redeem, the issuer has


                                       50
<PAGE>

a right to redeem and at the time the stock is issued it is more likely than
not that the stock will be redeemed, or has a dividend rate which varies with
interest rates or other indices. For purposes of this new provision of the
Code, however, preferred stock means stock which is limited and preferred as to
dividends and does not participate in corporate growth to any significant
extent. Counsel believes that because the combined company Series 1-B preferred
stock participates in dividends on an as converted basis and is entitled on
liquidation to no less than the proceeds it would receive on an as converted
basis, it should not be treated as "nonqualified preferred stock." However,
since the Internal Revenue Service has issued no interpretations of, or
guidance on, the new provisions of the Code dealing with "non-qualified
preferred stock," it is not possible to predict with absolute certainty whether
the Internal Revenue Service would take the position that the combined company
Series 1-B preferred stock is "nonqualified preferred stock."

     A former Impax shareholder who receives combined company stock without
recognition of gain as a result of the merger will have an aggregate basis in
that stock which is the same as his aggregate tax basis in the Impax stock
converted in the merger (reduced by any tax basis allocable to cash received
instead of a fraction of a share). The former Impax shareholder's holding
period for the combined company stock which he receives in the merger will
include the period during which he held the Impax stock. If an Impax
shareholder receives cash instead of a fraction of a share of the combined
company stock, the shareholder generally will recognize gain or loss for
federal income tax purposes, measured by the difference between the amount of
cash received and the portion of the tax basis of the share of Impax stock
allocable to the fraction of a share interest.

     The gain or loss resulting from receipt of cash in lieu of a fractional
share will be capital gain or loss and will be a long-term capital gain or loss
if the share of Impax stock has been held for more than one year at the time
the merger is effective. Because the receipt of cash instead of a fraction of a
share of stock is treated as if the holder had received the fraction of a share
and the company then redeemed that fractional share, it is possible that in
some circumstances the receipt of cash in lieu of a fraction share interest in
the combined company could be treated as a dividend. The shareholder would then
be required to pay tax at ordinary income rates on the cash received. The Code
contains a number of complex tests for determining whether a redemption should
be treated as a dividend or as an exchange of stock resulting in capital gain,
each of which depends on the degree to which a stockholder's interest in a
company is reduced by a redemption. On the basis of the Internal Revenue
Service's position as stated in a published ruling, Revenue Ruling 76-385,
which may be relied on by taxpayers, in the case of a holder of Impax stock
whose stock interest in the combined company (relative to the total number of
combined shares outstanding) is minimal and who exercises no control over the
affairs of the combined company, cash received in lieu of a fractional share
will result in the recognition of capital gain or loss. Other stockholders
should consult their tax advisors regarding the treatment of any cash received
in lieu of a fractional share. According to the terms of the merger agreement,
the maximum amount of cash which an Impax shareholder can receive in lieu of
fractional shares, and which therefore could be treated as a dividend, is an
amount less than the value of a single combined company share at the time of
the merger.

     Tax Implications to Global and Impax. No gain or loss will be recognized
for federal income tax purposes by Global or Impax as a result of the merger.

     This discussion is not intended to be a complete analysis or description
of all potential federal income tax consequences of the merger. In addition,
this discussion does not address tax consequences which may vary with, or are
contingent on, individual circumstances. Moreover, this discussion does not
address any non-income tax or any foreign, state or local tax consequences of
the merger or the merger proposal, or the tax consequences of any transaction
other than the merger and the merger proposal. Accordingly, you are strongly
urged to consult with your tax advisor to determine your particular federal,
state, local or foreign income or other tax consequences resulting from the
merger.


Regulatory Approvals

     Consummation of the merger is conditioned upon the receipt of all material
governmental authorizations, consents, orders and approvals, subject to waiver
of such conditions, in accordance with the terms of the merger agreement.
Although Global and Impax have agreed to use commercially reasonable efforts to
secure all such approvals, there can be no assurance regarding the timing of
such approvals or that such approvals will, in fact, be obtained.

Appraisal Rights


Delaware Appraisal Rights.


     Under Delaware law, where Global is incorporated, the holders of Global
common stock, Series C preferred stock and Series D preferred stock will be
entitled to certain "appraisal rights" in connection with the merger.


     The following summarizes the appraisal rights provided by Section 262 of
the Delaware General Corporation Law. However, the summary is not complete, and
you are encouraged to review a copy of Section 262, which has been included in
this joint proxy statement/prospectus as Annex C.


     Under Section 262, you will be entitled to an appraisal by the Court of
Chancery of the fair value of your shares as described below, if you:


     o were a holder of shares of the common stock, Series C preferred stock or
       Global Series D preferred stock on November 4, 1999,


     o continue to hold such shares through the merger,


     o do not vote in favor of the merger,


     o deliver to Global a written demand for appraisal of your shares prior to
       the special meeting for voting on the merger (a proxy or vote against the
       merger will not constitute the required written demand), and


     o fully comply with all the other applicable provisions of Section 262.


     Persons who meet the requirements described in this paragraph are referred
to below as "dissenting stockholders."


     If the merger is approved, then within ten (10) days after the effective
date of the merger, the combined company will notify each dissenting
stockholder that the merger has become effective.


     If you are a dissenting stockholder you will be entitled to request and
receive from the combined company a statement setting forth (1) the aggregate
number of shares not voted in favor of the merger and for which appraisal
demands have been asserted and (2) the aggregate number of dissenting
stockholders. The combined company will mail this statement to each requesting
dissenting stockholder on or before the later of (1) 10 days following receipt
by the combined company of the written request, or (2) December 23, 1999.


     Within 120 days following the effective date of the merger, either the
combined company or any dissenting stockholder may file a petition in the
Delaware Court of Chancery, demanding a determination of the value of the stock
of all dissenting stockholders. However, any dissenting stockholder may
withdraw his or her demand for appraisal and accept the terms offered under the
merger at any time within the 60 day period following the effective date of the
merger.


     At the hearing, the Court will determine those persons who are entitled to
appraisal rights, and may require such persons to submit their certificates of
stock to the Register in Chancery for notation of the appraisal proceedings. If
any person fails to comply with such an instruction, the Court may dismiss the
proceedings as to such person.


     After determining the persons entitled to an appraisal, the Court will
appraise the shares, determining the fair value, excluding any value arising
from the accomplishment or expectation of the merger, together with a fair rate
of interest. In determining fair value, the Court will consider all relevant
factors. In determining a fair rate of interest, the Court will consider the
rate of interest which the combined company would have had to pay to borrow
money during the appraisal proceedings.


     The Court will instruct the combined company to pay the fair value of the
shares, together with interest, if any, to each dissenting stockholder upon
surrender of the certificates representing his or her stock.


                                       52
<PAGE>

     The Court may, in its sole discretion, elect to allocate the costs of the
proceedings, as it determines appropriate. If any dissenting stockholder
requests, the Court may order that the expenses incurred by such dissenting
stockholder in connection with the appraisal proceedings, including without
limitation, reasonable attorneys' and experts fees, be charged pro rata against
the value of all of the shares entitled to an appraisal.

     After the merger, no dissenting stockholder will be entitled to vote his
or her stock for any purpose or to receive payment of dividends or other
distributions on the stock except dividends or distributions which were payable
prior to the merger.

     If no petition for an appraisal has been filed on or before the 120th day
following the merger, or if any stockholder has withdrawn his or her demand for
appraisal and accepted the merger (within the 60 day period following the
effective date of the merger)(or thereafter with the written approval of the
combined company), then the appraisal rights of such dissenting stockholder
will cease, except that any dismissal of an appraisal proceeding requires
approval by the Court of Chancery.

     If your Global stock certificate is not in your name and you wish to
exercise your appraisal rights described above, you should instruct the legal
certificate holder of such shares or obtain a proxy as to your shares. In
addition, you should cause the legal certificate holder to comply with, or you
should comply with, the other procedures required to perfect your appraisal
rights as described above.

     Appraisal rights are not available (a) with respect to the sale, lease or
exchange of all or substantially all of the assets of a corporation, (b) with
respect to a merger or consolidation by a corporation the shares of which are
either listed on a national securities exchange or are held of record by more
than 2,000 holders if the stockholders receive only shares of the surviving
corporation or shares of any other corporation that are either listed on a
national securities exchange or held of record by more than 2,000 holders, plus
cash instead of fractional shares, or (c) to stockholders of a corporation
surviving a merger if no vote of the stockholders of the surviving corporation
is required to approve the merger under certain provisions of Delaware law.

     Any demand, notices or other documents required to be sent to Global may
be sent to: Global Pharmaceutical Corporation, Attn: Cornel C. Spiegler, Castor
and Kensington Avenues, Philadelphia, Pennsylvania 19124.


California Dissenter Rights

     Under California law, where Impax is incorporated, the holders of Impax
common stock and preferred stock will be entitled to certain "dissenter rights"
in connection with the merger. The following summary is not a complete
statement of the dissenter rights provided by Chapter 13 of the California
Corporations Code, and you are encouraged to review a copy of Chapter 13 of the
California Corporations Code, which has been included in this joint proxy
statement/prospectus as Annex D.

     A holder of shares of preferred stock or common stock of Impax who does
not vote in favor of the merger, and fully complies with all the other
applicable provisions of Chapter 13 will be entitled, as a dissenting
shareholder, to require Impax to purchase any or all such holder's shares of
Impax stock for cash at their "fair market value" if the merger is consummated.


     The "fair market value" of the shares will be determined as of the day
before the first announcement of the terms of the merger, but will not include
appreciation or depreciation in consequence of the merger. The board of
directors of Impax will make a good faith determination of the "fair market
value" of any shares with respect to which the procedures of Chapter 13 have
been fully satisfied. If Impax and any dissenting shareholder cannot agree on
the "fair market value" of any such shares, then, at the request of Impax or
any dissenting shareholders, a California Superior Court will determine "fair
market value." The court's determination may be more or less than the
determination made by the board of directors.

     Within 10 days after shareholder approval of the merger, Impax will mail
to each shareholder who did not vote in favor of the merger a notice of such
approval. The approval notice will state the "fair market value" of dissenting
shares (as determined by Impax) and will describe the remaining procedures to
be followed to exercise dissenters' rights. The approval notice will be
accompanied by a copy of Chapter 13. The approval notice will be an offer by
Impax to purchase, at the price stated, any "dissenting shares."


                                       53
<PAGE>

     If you are a holder of Impax capital stock and you wish to exercise your
dissenter's rights with respect to any shares, you must refrain from voting in
favor of approval of the merger. However, merely not voting will not be
sufficient. You must deliver to Impax, on or before the 30th day following
Impax's mailing of the approval notice: (i) a written demand that Impax
purchase your Impax shares in cash for "fair market value" and (ii) your Impax
stock certificate.

     In your written demand, you must state the number of shares which you are
demanding that Impax purchase, and you must state your determination of the
"fair market value" of such shares as of the day before the first announcement
of the terms of the merger. This written demand will be an offer by you to sell
the shares at such price. You may not withdraw your demand unless Impax
consents.

     You must submit your Impax stock certificate(s) for those shares you are
offering to sell. These stock certificate(s) will be stamped with a statement
that the shares are dissenting shares or will be exchanged for certificates
which state that they represent "dissenting shares." If such certificates are
not so submitted, the shares represented thereby will lose their status as
dissenting shares.

     If your Impax stock certificate(s) are not in your name, and you wish to
dissent from the merger you should instruct the legal certificate holder of
such shares or obtain a proxy as to such shares. In addition, you should cause
the legal certificate holder to comply with, or you should comply with, the
other procedures required to perfect dissenters' rights, including not voting
in favor of the merger and submitting the written demand and your stock
certificates to Impax, all as described above.

     If you have complied with all the conditions referred to above, and you
and Impax agree upon the price to be paid for such shares, Impax will pay the
agreed price plus interest from the date of agreement within 30 days after you
and Impax agree upon the price. If Impax denies that you are entitled to
payment, or if Impax and you disagree as to the "fair market value" of such
shares, you may file a complaint in the Superior Court in the county of Alameda
in the State of California requesting the court to determine whether you are
entitled to payment or to determine the "fair market value" of your shares, or
both, or may intervene in any action pending on such complaint. This complaint
must be filed within six months after the date the notice of approval of the
merger was mailed to Impax shareholders. If you do not file a complaint within
the six-month period, you will cease to be entitled to require Impax to
purchase any shares. The cost of the action will be assessed or apportioned as
such court considers equitable, but if the "fair market value" exceeds the
price offered by Impax, Impax will be required to pay such costs (including, in
the court's discretion, attorney's fees, fees of expert witnesses and interest
from the date of delivery to Impax of the written demand for the repurchase of
shares and delivery of Impax stock certificate, if the value is determined to
exceed 125% of the price offered to such stockholder by Impax.)

     Shareholders of a California corporation whose shares are listed on a
national securities exchange or on a list of over-the-counter margin stocks
issued by the Board of Governors of the Federal Reserve System generally do not
have such appraisal rights unless the holders of at least five percent (5%) of
the class of outstanding shares claim the right of the corporation or any law
restricts the transfer of the shares.

     Please send your written demand, stock certificate(s), questions or
comments to Impax's corporate counsel: Impax Pharmaceuticals, Inc., c/o The Law
Offices of Laurie A. Miller, Esq., 3542 Oak Knoll Drive, Redwood City,
California 94062.

                             THE MERGER AGREEMENT


     This section of the joint proxy statement/prospectus describes material
terms of the merger agreement. We recommend that you read carefully the
complete text of the merger agreement for the precise legal terms of the merger
agreement and other information that may be important to you. The merger
agreement is included in this joint proxy statement/prospectus as Annex A.


Form of Merger

     If all the conditions to the merger are satisfied or waived in accordance
with the merger agreement, Impax will merge with and into Global. Global's
corporate existence will not be affected by the merger, but its certificate of
incorporation will be amended to increase the number of shares of common stock
Global is authorized to issue and to change the name of the combined company to
Impax Laboratories, Inc. After the merger, the corporate existence of Impax
will cease.

     The combined company will have its headquarters in Hayward, California.


Consideration to be Received in the Merger

     On the date the merger becomes effective, the following shares and all
rights with respect to those shares will be converted into capital stock of the
combined company as described below:

   o each outstanding share of Impax common stock, Series A preferred stock
     and Series B preferred stock will be converted into 3.3358 shares of
     combined company common stock;

   o each outstanding share of Impax Series C preferred stock will be
     converted into 5.849 shares of combined company common stock;

   o every 20 outstanding shares of Impax Series D preferred stock will be
     converted into one share of combined company Series 1-B preferred stock;

   o each outstanding share of Global Series C preferred stock will be
     converted into 50 shares of combined company common stock; and

   o each outstanding share of Global Series D preferred stock will be
     converted into one share of combined company Series 1-A preferred stock.

     We cannot predict the market price of the Global common stock on the date
the merger becomes effective. The exchange ratios are fixed in the merger
agreement. Consequently, the market value of the shares of combined company
common stock that stockholders of Impax will have the right to acquire on the
date the merger becomes effective may vary significantly from the market value
of those same shares if the merger was completed on the date of this joint
proxy statement/prospectus.

     Assuming the merger is consummated, the exchange will occur by operation
of law without any action on the part of the Impax or Global stockholders.
Treasury shares held by Impax or shares of Impax held by Global will not be
converted.


Exchange of Shares


     Prior to the completion of the merger, we will appoint an exchange agent.
On the date the merger becomes effective, the combined company will deposit
with the exchange agent certificates representing shares of combined company
common stock, Series 1-A preferred stock and Series 1-B preferred stock that
will be issued in exchange for certificates representing shares of Impax common
stock, Impax preferred stock, Global Series C preferred stock and Global Series
D preferred stock. Soon after the completion of the merger, the combined
company or the exchange agent will send a letter to each person who was an
Impax stockholder or a holder of Global Series C or Global Series D preferred
stock on the date the merger becomes effective. The letter will contain
instructions on how to surrender stock certificates to the exchange agent and
receive certificates for shares of the combined company. Stockholders should
not send in their stock certificates until they receive the letter from the
combined company or the exchange agent.


                                       55
<PAGE>

     The combined company will not issue any fractions of a share resulting
from the conversion. Instead, stockholders will receive cash for the value of
any fraction of a share to which they would otherwise have been entitled to
receive due to the merger. This cash payment will equal the average of the
daily closing prices for a share of Global common stock on the Nasdaq Small Cap
Market for the twenty consecutive trading days ending on the second trading day
immediately prior to completion of the merger. The cash value for fractional
shares of Series 1-B preferred stock will be based on the cash value of the
fractional common stock into which the shares of preferred stock can be
converted.

     Impax stockholders and holders of Global's Series C and Series D preferred
stock will not be entitled to receive any dividends or other distributions
payable by the combined company until they exchange their stock certificates
for certificates representing shares of combined company common stock or Series
1-A or Series 1-B preferred stock, as applicable. Once they deliver their stock
certificates to the exchange agent, such holders will receive, subject to
applicable laws, any accumulated dividends and distributions, without interest.



Treatment of Impax Stock Options and Warrants

     On the date the merger becomes effective, each outstanding and unexercised
option to purchase shares of Impax common stock will be converted into an
option to purchase shares of combined company common stock. The number of
shares of combined company common stock covered by such new option will be
determined by multiplying the number of shares of Impax common stock subject to
the original option by the exchange ratio. The exercise price for such option
will equal the exercise price under the original option divided by the exchange
ratio. The new option will otherwise have the same terms and conditions as the
original option to purchase Impax common stock, except that, at the combined
company's election, such new option may be re-issued under and subject to the
terms and conditions of the stock incentive plan of the combined company. In
addition, as described more fully under the Section heading "Management of the
Combined Company" later in this joint proxy statement/prospectus, all stock
options held by current directors of Global or Impax who will not continue to
serve as a director of the combined company after the merger, will be converted
into a five-year warrant to purchase an equivalent number of shares of the
combined company's common stock.


Representations and Warranties in the Merger Agreement

     In the merger agreement, we make representations and warranties to each
other about our companies with respect to, among other things:

     o due organization and good standing;

     o capitalization, ownership of subsidiaries and other investments;

     o corporate power;

     o absence of any breach of organizational documents or material agreements
       as a result of the contemplated transactions;

     o accuracy of our filings and our financial statements;

     o absence of specified changes;

     o litigation and violations of law;

     o information supplied for use in this joint proxy statement/prospectus;

     o employee matters, labor relations, environmental matters and tax matters;
       and

     o required board of directors and stockholder approvals with respect to the
       contemplated transactions.


No Solicitation of Transactions


     We have agreed that neither we nor our employees, subsidiaries or advisors
will, directly or indirectly through another person:


                                       56
<PAGE>

     o solicit, initiate or encourage, or knowingly take any other action
       designed to facilitate, any alternative transaction; or

     o participate in any discussions regarding any alternative transaction.

     However, this prohibition will not apply if at any time prior to receiving
stockholder approval, the Impax board of directors or the Global board of
directors, determines in good faith that the failure to provide information or
participate in negotiations or discussions would result in a reasonable
possibility that the board of directors would breach its fiduciary duties to
stockholders. In that case, a party may, in response to an unsolicited superior
proposal, furnish information with respect to it to any person pursuant to a
customary confidentiality agreement and participate in negotiations regarding
the proposal. Each party will promptly notify the other party orally and in
writing of any request for information or of any proposal in connection with an
alternative transaction, its material terms and conditions and the identity of
the person making the request or proposal.


Benefits Matters


     We have agreed that the Global and Impax benefit plans that were in effect
when the merger agreement was signed will remain in effect until the merger is
completed unless we agree otherwise. In the ordinary course of business, the
combined company will arrange for standard health plans and benefits to its
employees. When the merger is completed, all employees will receive full credit
for their credited service with either company in determining the amount of,
eligibility for, and vesting of, certain benefits.

     After the merger, any stock-based compensation or incentive payments that
are based on Impax common stock will be based upon the combined company common
stock in accordance with the exchange ratio.


Covenants in the Merger Agreements


     The merger agreement provides that, until the merger has been completed,
we will conduct our respective businesses in the ordinary course and consistent
with past practice. We have agreed to use our commercially reasonable efforts
to:

     o preserve our respective business organizations;


     o retain the services and relationships with those employees and
       consultants whose services are integral to the operation of the business
       as presently conducted; and


     o preserve our respective existing relationships with significant customers
       and suppliers.


     During this interim period, we have agreed that neither of us will take
certain actions without the consent of the other party. More specifically, we
have agreed:


     o Issuance of Stock. In general, we each will preserve our existing
       capitalization. However, both of us are permitted to issue or grant stock
       options under our employee stock equity plans, in a manner consistent
       with past practice and which do not exceed an aggregate of 50,000 shares.


     o Acquisitions. Neither of us will merger with or acquire any business
       organization or make any investment in an entity.


     o Dispositions. Each of us will not sell, license, dispose of or encumber
       any of our property or assets in excess of $10,000 except in ordinary
       course of business.


     o Incurring Indebtedness. Neither of us may incur additional indebtedness
       other than pursuant to credit agreements already in existence.


     o Severance, Retention and Incentive Arrangements. Neither of us may put in
       place any new or increased severance or retention programs or
       arrangements. This restriction does not apply to arrangements that are
       required by law or are consistent with past practice, up to a maximum of
       $150,000 in the aggregate.


                                       57
<PAGE>

     o Increased Compensation or Payments Under Plans. Neither of us will
       increase compensation, make payments under or amend any benefit plan or
       enter into or amend any employment or consulting agreement. However, we
       may take actions of this type if the actions are consistent with past
       practice.

     o Accounting Policies. Neither of us may change its accounting policies or
       procedures as in effect at December 31, 1998.

     o Stock Exchange Listing. Global will not cause its common stock to cease
       to be traded on the Nasdaq Small Cap Market.

     o Amend Contracts. Neither of us will terminate or change the terms of any
       material contract, or waive, release or assign any material rights or
       claims.

     o Expenditures. Neither of us will make or commit to make any expenditures
       exceeding $100,000 for any single item, except as described in or as
       consistent with financial budgets delivered to the other party. However,
       Impax may incur expenditures up to $250,000 in the aggregate to obtain
       building permits and architectural drawings in connection with
       constructing a manufacturing facility at Impax's Hayward, California
       facility.

     o Charter Documents. Neither of us will amend our charter or bylaws.

     o Stockholder Rights Plan. Neither of us will adopt any agreement or plan
       that gives any stockholder or group of stockholders any rights which
       could impede or restrict the merger.

     o Tax Matters. Neither of us will amend our tax returns or make any
       election or agreement with the IRS concerning any tax accounting matters.

     o Litigation. Neither of us will initiate, compromise or settle any pending
       lawsuits or arbitration proceedings.

     o Dividends. Neither of us will declare or pay any dividends on or make any
       other distributions in respect of its stock, or effect any stock split,
       reclassification or combination.

     o Acceleration of Options. Neither of us will accelerate, amend or change
       the period of exercisability of options or restricted stock or purchase
       any of its own outstanding stock, except as contemplated for
       non-continuing directors.

     o Liquidity of Funds. Neither of us will invest funds in debt securities or
       other instruments, which mature more than one year after the date of
       investment.


Conditions in the Merger Agreement


     The merger agreement contains conditions to the obligation of Global and
Impax to complete the merger. Neither Global nor Impax will be obligated to
complete the merger unless:

     o Stockholder Approval. The stockholders of Impax and Global have approved
       their respective merger proposals, as described in this joint proxy
       statement/prospectus;

     o Legality. No federal, state or foreign statute, rule, regulation,
       executive order, decree, injunction or administrative order prohibits
       consummation of the merger or otherwise has the effect of making the
       merger illegal;

     o Regulatory Matters. We have obtained all approvals necessary to complete
       the merger which, if not obtained, would have a material adverse effect
       on Impax, Global or the combined company.

     o Registration Statement. The registration statement relating to this joint
       proxy statement/prospectus is effective, and no stop order suspending
       effectiveness or proceedings seeking such a stop order is in effect;

     o Nasdaq Listing. The shares of combined company common stock issuable in
       the merger have been approved for listing on the Nasdaq Small Cap Market.


                                       58
<PAGE>

   In addition, Global will not be required to complete the merger unless:

   o Representations and Warranties. The representations and warranties made
     by Impax in the merger agreement are true and correct on the date that the
     merger is completed, unless the failure to be true and correct does not,
     or would not reasonably be expected to, result in a material adverse
     effect on Impax or the combined company.

   o Performance of Obligations. Impax has performed all material obligations
     required to be performed by it in the merger agreement.

   o Permits and Licenses. All permits, licenses and governmental
     authorizations required to conduct Impax's business must be in effect, and
     Impax has obtained any necessary approvals for the continued effectiveness
     of these authorizations after the merger, except where the lack of such
     authorizations will not have a material adverse effect on Impax or the
     combined company.

   o Dissenting Stockholders. The holders of not more than 10% of the value of
     Impax's outstanding shares of common stock and preferred stock have
     perfected their dissenter rights under California law. (See pages 53-54
     for a description of dissenter rights.)

   o Stockholders' Agreement. Key stockholders of Impax have entered into a
     stockholders' agreement, which provides that certain groups of
     stockholders may designate certain directors, and that all parties to the
     stockholder's agreement will vote in a manner consistent to cause the
     election of each parties' designated candidates.

   o Fairness Opinion. Global has received an opinion from Gruntal & Co.,
     L.L.C. that the consideration to be paid in the merger is fair, from a
     financial point of view, to Global and its holders of common stock.

   o Opinion of Counsel. Global has received the opinion from Laurie Miller,
     corporate counsel to Impax, that Impax has the authority to enter into the
     merger agreement and such other matters as are mutually agreed upon.

   o Environmental Assessment. Global has received a satisfactory
     environmental evaluation of Impax's facilities at Hayward, California.

   o Consents. Impax has received all consents required for completion of the
     merger under any agreement to which Impax is a party.

   o Election of Directors. The stockholders of the combined company have
     elected directors in accordance with the merger agreement and the
     stockholders' agreement.

   o Election of Officers. The combined company's directors have elected the
     officers stated in the merger agreement.

   o Employment Agreements. Global receives a fully signed employment
     agreement between the combined company and each of Charles Hsiao, Larry
     Hsu and Barry R. Edwards.

   o Voting Agreements. Global receives voting agreements from certain
     significant senior executive officer or director shareholders of Impax,
     which provide that those shareholders will vote in favor of the merger.

   o Escrow Agreement. Global receives an escrow agreement, signed by each of
     the shareholders of Impax, which provides that approximately 10% of the
     shares of the combined company stock to be received by Impax shareholders
     as a result of the merger will be held in escrow for the purpose of
     securing the indemnification obligations of these shareholders contained
     in the merger agreement.

Impax will not be required to complete the merger unless:

   o Representations and Warranties. The representations and warranties made
     by Global in the merger agreement are true and correct on the date that
     the merger is completed, unless the failure to be true and correct does
     not, or would not reasonably be expected to, result in a material adverse
     effect on Global or the combined company.


                                       59

   o Performance of Obligations. Global has performed all material obligations
     required by the merger agreement.

   o Dissenting Stockholders. The holders of not more than 10% of the value of
     Global's outstanding shares of common stock and preferred stock have
     perfected their appraisal rights under Delaware law. (See pages 52-53 for
     a description of appraisal rights.)

   o Opinion of Counsel. Impax has received the opinion from Fulbright &
     Jaworski L.L.P., corporate counsel to Global, that Global has the
     authority to enter into the merger agreement and such other matters as are
     mutually agreed upon.

   o Consents. Global has received all consents required for completion of the
     merger under any agreement to which Global is a party.

   o Permits and Licenses. All permits, licenses, product approval
     applications and governmental authorizations required to conduct Global's
     business are in effect, and Global has obtained any necessary approvals to
     assure that these authorizations will remain ongoing after the merger,
     except where the lack of such authorizations will not have a material
     adverse effect on Global or the combined company.

   o Environmental Assessment. Impax has received a satisfactory environmental
     evaluation of Global's facilities at Philadelphia, Pennsylvania.

   o Stockholders' Agreement. Certain key stockholders of Global have entered
     into a stockholders' agreement, which provides that certain groups of
     stockholders may designate certain directors, and that all parties to the
     stockholder's agreement will vote in a manner consistent to cause the
     election of each parties' designated candidates.

   o Adoption of New Equity Incentive Plan. Global's directors and
     stockholders have approved an equity incentive plan with 2,400,000 shares
     of Global's common stock reserved for grants.

   o Election of Directors. The stockholders of the combined company will
     elect its directors in accordance with the merger agreement and the
     stockholders' agreement.

   o Election of Officers. The combined company's directors have elected the
     officers stated in the merger agreement.

   o Employment Agreement. Impax receives a fully executed employment
     agreement between the combined company and each of Barry R. Edwards,
     Charles Hsiao and Larry Hsu.

   o Adoption of the Amendment to Global's Certificate of Incorporation.
     Global's directors and stockholders have approved and adopted an amendment
     to Global's Certificate of Incorporation, increasing the authorized
     capital stock of Global to an aggregate of 50,000,000 shares of common
     stock and changing the name of Global to "Impax Laboratories, Inc."


     Under the merger agreement, "material adverse effect" generally means any
change in or effect on the business of the applicable company that is or will
be materially adverse to the business, operations, properties, condition,
assets, liabilities or regulatory status of that company and its subsidiaries
taken as a whole, but does not include the effects of changes that are
generally applicable in the pharmaceutical industry, the United States economy
or the United States securities markets if the effect on Impax or Global is not
materially disproportionate relative to the effect on the other.


Stockholders' Meetings


     We have agreed to hold meetings of our stockholders to vote on the merger
proposals promptly after the Securities and Exchange Commission declares this
joint proxy statement/prospectus effective. The Impax board of directors has
unanimously recommended approval of the Impax merger proposal, and the Global
board of directors has unanimously recommended approval of the Global merger
proposal. We have agreed that each of our boards of directors will not:


                                       60
<PAGE>

     o except as discussed below, withdraw or modify in a manner adverse to the
       other party, its recommendation of approval;

     o recommend any "alternative transaction"; or

     o cause either of us to enter into any agreement related to any alternative
       transaction.

     However, if a board of directors receives a "superior proposal" (as
described below) and determines in good faith that the failure to do so would
result in a reasonable possibility that the board of directors would breach its
fiduciary duties to its stockholders, the board of directors may inform
stockholders that it no longer recommends approval of the merger between Global
and Impax. In such a case, this agreement can be terminated by the party
receiving the superior proposal and such party will pay the termination fees to
the other party as described below.

     An "alternative transaction" is any inquiry or proposal that constitutes
or could reasonably be expected to lead to a proposal or offer to acquire all
or a substantial part of the business, property or capital stock of Global or
Impax.

     A "superior proposal" means any proposal made by a third party to enter
into an alternative transaction which the board of directors determines in its
good faith judgment to be more favorable to its stockholders than the merger,
taking into account all relevant factors.


Board of Directors


Directors and Observers

     For three years following completion of the merger, the election of
directors and officers will be impacted by a stockholders' agreement entered
into by certain significant stockholders of Global and Impax. Parties to the
stockholders' agreement will collectively own approximately 64% of the voting
power of the combined company after the merger. However, voting in accordance
with the stockholders' agreement is subject to each person's fiduciary duty as
an officer and/or director.

     The merger agreement and the stockholders' agreement provides that upon
completion of the merger, the board of directors of the combined company will
consist of ten members. The current members of Global's board of directors will
propose the election of two directors, the current members of Impax's board of
directors will propose the election of three directors, and the current members
of the board of directors of both Global and Impax will jointly propose the
election of (1) Barry R. Edwards, Charles Hsiao and Larry Hsu, and (2) two
mutually agreeable independent directors.

     The current members of the board of directors of Global will designate one
board observer and the current members of the board of directors of Impax will
designate one board observer.

     You should refer to the Section entitled "Management of the Combined
Company" for a list of, and additional information about, the board nominees
and observers.


Officers


     The merger agreement and the stockholders' agreement provide that from
completion of the merger until the third anniversary of the merger, the
following persons will serve as executive officers of the combined company in
the positions set forth below:



     Charles Hsiao, Ph.D.     Chairman and Co-Chief Executive Officer
     Barry R. Edwards         Co-Chief Executive Officer
     Larry Hsu, Ph.D.         President and Chief Operating Officer


Continued election of the above described persons will be subject to the
fiduciary duties of the then-existing members of the board of directors of the
combined company.


                                       61

Transition Planning


     Charles Hsiao, Ph.D., as Chairman and Chief Executive Officer of Impax,
Larry Hsu, Ph.D., as President of Impax, and Mr. Barry R. Edwards as President
and Chief Executive Officer of Global, are responsible for coordinating all
aspects of transition planning and implementation relating to the merger. Dr.

manner in which to best organize and manage our businesses after the merger,
and coordinate policies and strategies with respect to regulatory authorities
and bodies, in all cases subject to applicable law.


Other


     The merger agreement contains other covenants relating to preparation and
distribution of this joint proxy statement/prospectus, public announcements,
mutual notification of certain matters, access to information, and cooperation
regarding certain filings with governmental and other agencies and
organizations. In addition, the merger agreement contains a general covenant
requiring each of us to use commercially reasonable efforts to close the
merger, including obtaining required regulatory approvals.


Termination


     The merger agreement may be terminated at any time before the date the
merger becomes effective in any of the following circumstances:


     o by our mutual written consent;


     o if the merger is not completed by December 31, 1999. This termination
       right is not available to any party whose failure to fulfill any
       obligation has been the cause of, or resulted in, the failure of any
       condition to be satisfied;


     o by either party if a court or governmental entity has issued an order,
       decree or ruling or taken any other action permanently restraining,
       enjoining or otherwise prohibiting the merger, and the order, decree,
       ruling or other action has become final and nonappealable;


     o by either party if the other party breaches any of its representations,
       warranties, obligations or agreements contained in the merger agreement,
       and that breach has not been cured within five days following receipt of
       written notice of breach from the non-breaching party;


     o by either party if the board of directors of the other party (1)
       withdraws, materially modifies or fails to reaffirm its approval of the
       merger, (2) recommends any alternative transaction with a third party, or
       (3) resolves to take any such action (any of which we refer to as a
       "withdrawal of approval"); or


     o by either party if any of the required approvals of the stockholders of
       Impax or of Global are not obtained at a stockholders meeting of either
       company, including any adjournments thereof.


Termination Fees and Expenses


     Global is obligated to pay to Impax a termination fee of $500,000, and to
reimburse Impax for its costs in connection with the merger, up to $500,000, if
the merger agreement is terminated:


     o because Global's board of directors withdraws, or adversely modifies, its
       approval of the merger, or approves or recommends an alternative
       transaction with another company;


     o because Global violates certain of its obligations under the merger
       agreement and does not remedy the violation; or


                                       62
<PAGE>

     o because Global fails to obtain the requisite stockholder approval of the
       merger if at the time of the failure there has been an alternative
       transaction with another company announced which is then available.


     In addition to the fees and expenses specified above, Global is obligated
to pay Impax an additional termination fee of $500,000 in the event either
party terminates the merger agreement due to Global's failure to obtain the
requisite stockholder approval for the merger.


     Impax is obligated to pay to Global a termination fee of $500,000, and to
reimburse Impax for its costs in connection with the merger, up to $500,000, if
the merger agreement is terminated:


     o because Impax's board of directors withdraws or adversely modifies, its
       approval of the merger, or approves an alternative transaction with
       another company; or


     o because Impax violates certain of its obligations under the merger
       agreement and does not remedy the violation.


     Except as described above, we will each pay our own costs and expenses
incurred in connection with the merger agreement and the related transaction.
However, we will share equally the expenses incurred in connection with the
printing of this joint proxy statement/prospectus and the related filing fees.


Indemnification and Escrow

     At the time the merger is consummated, 10% of the aggregate number of
shares of the combined company being received by the Impax shareholders in the
merger. will be deposited into an escrow account, comprised of 1,690,274 shares
of common stock of the combined company and 17,000 shares of Series 1-B
preferred stock. These shares will be deposited for the purpose of securing the
indemnification obligations of the holders of Impax stock as detailed in the
merger agreement. In addition, Global will be required to reserve 1,020,045
shares of the combined company stock in order to indemnify holders of Impax
stock to the extent required in the merger agreement.


                                       63

          DESCRIPTION OF GLOBAL'S CAPITAL STOCK FOLLOWING THE MERGER

     Upon the consummation of the merger, Global will be renamed Impax
Laboratories, Inc. The Global certificate of incorporation, as in effect prior
to the merger and as amended pursuant to the merger proposal approved at the
Global special meeting, will be the certificate of incorporation of the
combined company.


Authorized capital stock

     As of the date of this joint proxy statement/prospectus, the authorized
capital stock of Global consists of 17 million shares of common stock and 2
million shares of preferred stock. As of August 15, 1999, there were
approximately 7,254,053 shares of Global common stock, 9,000 shares of Global
Series C preferred stock and 50,000 shares of Global Series D preferred stock
outstanding. If at the Global special meeting, the stockholders approve the
increase in the authorized capital stock of Global, the Global certificate of
incorporation will authorize the issuance of up to 50 million shares of Global
common stock, in addition to the existing authorization to issue up to 2
million shares of Global preferred stock. Global has previously filed a
certificate with the Delaware authorities designating two new classes of
preferred stock called "Series 1-A Convertible Preferred Stock," and "Series
1-B Convertible Preferred Stock" and extinguishing its existing Series A,
Series B, Series C and Series D preferred stock. This designation of the new
series of preferred stock and extinguishment of the existing series of
preferred stock becomes effective at the closing of the merger.

     Global expects to issue approximately 16.9 million shares of combined
company common stock to the holders of Impax common stock, Series A preferred
stock, Series B preferred stock and Series C preferred stock in exchange for
their Impax stock. An additional 450,000 shares of combined company common
stock is expected to be issued in exchange for Global's Series C preferred
stock. The shares of Global common stock underlying Global's Series C preferred
stock were registered pursuant to Registration Statement No. 333-69395 on file
with the SEC. Based on these expected issuances, the combined company will have
approximately 24,600,000 shares of common stock outstanding after the merger
(assuming no shareholders exercise their dissenters rights and there are no
exercises of stock options or warrants). In addition, pursuant to the merger,
each 20 shares of Impax Series D preferred stock will be converted into one
share of Global Series 1-B preferred stock. Based upon this exchange rate, the
combined company will have approximately 170,000 shares of Series 1-B preferred
stock outstanding after the merger (assuming no Impax shareholders exercise
their dissenters rights). An additional 50,000 shares of Series 1-A preferred
stock will be issued in exchange for Global's Series D preferred stock.


Common stock

     Subject to the rights of the holders of shares of preferred stock, holders
of shares of the combined company's (i.e., Global's) common stock:

     o are entitled to receive dividends when and as declared by the Global
       board from legally available funds;

     o are entitled, upon any liquidation, dissolution or winding up of Global,
       to a pro rata distribution of the assets and funds available for
       distribution to stockholders;

     o are entitled to one vote per share on all matters on which stockholders
       generally are entitled to vote; and

     o do not have preemptive rights to subscribe for additional shares of
       Global common stock or securities convertible into shares of Global
       common stock.

     The holders of common stock vote together as a single class with the
holders of the preferred stock on all matters, except as otherwise provided by
law or with respect to rights specifically granted to holders of the preferred
stock (see page 65 for a listing of these rights).

     The Global common stock is listed on the Nasdaq Small Cap Market under the
symbol "GLPC."


Preferred stock

     The Global board has authorized two new series of preferred stock
designated as Series1-A and Series1-B preferred stock, with the rights,
preferences and privileges described below. The outstanding shares of Global


                                       64
<PAGE>

Series D preferred stock will be converted into Series 1-A preferred stock and
the outstanding shares of Impax Series D preferred stock will be converted into
Series 1-B preferred stock. The Series 1-A preferred stock and Series 1-B
preferred stock will be identical in all respects, except for a difference in
the rate at which shares may be converted into Global common stock and,
consequently, the number of votes per share of preferred stock.

     As of the closing of the merger, there will be 50,000 shares of Series 1-A
preferred stock issuable upon conversion of the Global Series D preferred stock
and 170,000 shares of Series 1-B preferred Stock issuable upon conversion of
the Impax Series D preferred stock.

     Dividends. The shares of Series 1 preferred stock are entitled to receive
dividends on an as-converted basis with the outstanding shares of common stock,
payable when and as declared by the combined company's board of directors.


     Liquidation preference. If there is a liquidation, dissolution or winding
up of the combined company, the holders of Series 1 preferred stock are
entitled to receive a payment on their shares before any payment may be made to
the holders of common stock. This preference payment to the preferred
stockholders is the greater of:


     o $100 per share plus any accrued and unpaid dividends on the Series 1
       preferred stock;


     o the pro rata share of the assets of the combined company, determined as
       if the shares of Series 1 preferred stock had been converted into common
       stock; or


     o a 12% annualized rate of return on the dollar value of their initial
       investment.


     Voting. Each holder of Series 1 preferred stock is entitled to that number
of votes as is equal to the number of shares of common stock into which the
preferred stock can then be converted, on all matters to be voted on by the
stockholders. In the case of Series 1-A preferred stock, each share initially
can be converted into 50 shares of common stock and so has 50 votes. In the
case of Series 1-B preferred stock, each share initially can be converted into
approximately 66.7 shares of common stock and so has approximately 66.7 votes.
The holders of the Series 1 preferred stock and the holders of the common stock
vote together as a single class, except as provided by law. In addition,
holders of the Series 1 preferred stock, as a class, have to approve certain
actions, including:


     o the issuance of any class or series of stock which would rank senior to
       the Series 1 preferred stock as to dividends or upon liquidation;


     o the amendment of the Global certificate of incorporation or by-laws in a
       way that would impair or reduce the rights of the Series 1 preferred
       stock;


     o the liquidation or dissolution of Global;


     o any proposed transaction eliminating the public trading market for the
       Global common stock;


     o to redeem or repurchase any outstanding Global capital stock;


     o the incurrence of debt or encumbrance of assets over $15 million; or


     o the entrance by Global into any other line of business.


     Election of directors. There are four major holders of the Series 1
preferred stock: China Development Industrial Bank; Chemical Company of
Malaysia Berhad; President (BVI) International Investment Holdings; and two
affiliated Fleming US Discovery funds. Each of these four holders has the right
to elect one member of the combined company's board so long as the holder
continues to own at least 40% of the Series 1 preferred stock that it held on
the effective date of the merger. A person which acquires any such 40% position
will inherit the right to elect a director of the company in place of the
original holder.


     Conversion. Each share of Series 1 preferred stock is convertible into a
number of shares of combined company common stock. The number of shares of
common stock is determined by adding $100 plus the


                                       65
<PAGE>
amount of all accrued but unpaid dividends on that share of preferred stock,
and then dividing by the then applicable conversion price of that Series 1
preferred stock. The initial conversion price for the Series 1-A preferred
stock is $2.00. The initial conversion price for the Series 1-B preferred stock
is $1.4989.

     The conversion price of the Series 1 preferred stock will be adjusted for
certain events, including:

     o any subdivision, combinations or reclassifications of the combined
       company's common stock;

     o any payment, issuance or distribution by the combined company of a stock
       dividend, debt securities or assets; and

     o the issuance of common stock or securities convertible into common stock
       for a price per share of less than the conversion price at that time.

     Up to $10 million of additional securities can be issued, as well as
issuances of shares of common stock pursuant to stock options granted under
approved stock option plans, currently outstanding warrants, or to business
partners, without the conversion price of the Series 1 preferred stock being
adjusted.

     Redemption. The combined company is required to redeem, on March 31, 2004,
all of the outstanding shares of Series 1 preferred stock at a price per share
equal to $100 plus all declared but unpaid dividends. The holders of the Series
1 preferred stock can also require the redemption of their preferred stock upon
the happening of certain events, including the sale of the combined company or
its assets, the elimination of a public trading market for shares of its common
stock, or the insolvency of or bankruptcy filing by the combined company. The
redemption price can be paid, at the company's option, in cash or shares of
common stock, discounted, in the case of shares, by 10% from the then current
market price of the common stock.

     Preemptive rights. The holders of Series 1 preferred stock have preemptive
rights entitling them to purchase a pro rata share of any capital stock,
including securities convertible into capital stock of the combined company,
issued by the combined company in order for the holders of Series 1 preferred
stock to retain their percentage interest in the combined company. However, the
combined company can issue shares of its capital stock under certain
circumstances without triggering the preemptive rights of the Series 1
preferred stock, including the following:

     o as pro rata dividends to all holders of common stock,

     o as stock options to employees, officers and directors,

     o in connection with a merger, acquisition or business combination,

     o for consideration of less than $500,000 in any single permitted
       transaction and for less than $1,000,000 in the aggregate for all
       permitted transactions, and

     o up to 300,000 shares issued during the first five years in connection
       with a business relationship.

     Call privileges. After two years, the combined company has the right to
purchase all of the outstanding shares of Series 1 preferred stock if the
market price of a share of combined company common stock is at least equal to
the higher of:

     o 300% of the applicable conversion price of the Series 1 preferred stock
       at that time; or

     o $6.00 per share.

     In addition, the common stock must have traded on its principal market for
a period of 30 consecutive dates with an average daily volume in excess of
50,000 shares for the 30-day period. The price per share of any shares being
repurchased is $100 plus all declared but unpaid dividends.

     In addition, pursuant to its certificate of incorporation, the combined
company will be authorized to issue "blank check" preferred stock. This will
enable the board of directors of the combined company, from time to time, to
create one or more new series of preferred stock in addition to the Series 1
preferred stock. The new

                                       66
<PAGE>

series of preferred stock can have the rights, preferences, privileges and
restrictions designated by the combined company's board of directors. When, and
if, any new series of preferred stock is issued, it could affect, among other
things, the dividend, voting and liquidation rights of the combined company
common stock.


Warrants

     As of the date of this joint proxy statement/prospectus, Global has
outstanding warrants to purchase 1,375,000 shares of Global common stock at
exercise prices ranging from $1.75 to $13.175 per share. In addition, Global
issued a warrant which can be exercised for 40,000 shares of Global common
stock for each $1,000,000 in gross profit earned by Global under a business
relationship with an unaffiliated entity, up to a total of 700,000 shares. This
warrant is exercisable at a price of $8.50 per share of Global common stock.

     As of the date of this joint proxy statement/prospectus, Impax has
outstanding warrants to purchase 560,000 shares of Impax common stock at an
exercise price of $2.50 per share of Impax common stock. If the merger is
consummated, these warrants will be converted into warrants to purchase
1,868,048 shares of combined company common stock at an exercise price of $0.75
per share.

     In addition, at the closing of the merger, the combined company will
replace the non-employee director stock options held by all current
non-employee directors of Global and Impax who will cease to be directors of
the combined company, with five-year common stock warrants. The warrants will
be exercisable, in the case of Global non-continuing directors, for the same
number of shares which could be purchased under the options (whether or not
then vested) and at the same exercise price. In the case of Impax
non-continuing directors, the warrants will be exercisable for the same number
of shares which could be purchased under the Impax options (whether or not then
vested) and at the same exercise price, both adjusted for the exchange ratio of
3.3358 shares of Global common stock for each share of Impax common stock. At
the effective time of the merger, Global expects to issue an aggregate of
355,650 warrants to these non-continuing directors, at exercise prices ranging
from $2.065 to $4.125 per share.


Transfer agent and registrar

     The transfer agent and registrar for the Global common stock is
Continental Stock Transfer & Trust Company.

However, this requirement only applies to
corporations that have shares held of record by
more than 100 persons. Because Impax has less

subject to this provision.

An "Interested Party" for purposes of the California
Corporations Code means a person who is a party

indirectly controlled by, an officer or director of the
corporation or (3) is an entity in which a material
financial interest is held by any director or

The California Corporations Code also provides that

director has a material financial interest are not void
or voidable if the material facts as to the transaction
and as to the director's interest are fully disclosed

asserting the validity of the contract or transaction

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

     When used in this discussion, the words "believes," "anticipates,"
"expects," and similar expressions are intended to identify forward-looking
statements. Such statements are subject to certain risks and uncertainties
which could cause actual results to differ materially from those projected.

     Global's business and results of operations are affected by a wide variety
of factors that could materially and adversely affect Global and its actual
results, including, but not limited to, the ability to obtain and maintain
governmental approvals on additional products, the ability to adequately fund
its operating requirements, the impact of competitive products and pricing,
product demand and market acceptance, new product development, reliance on key
strategic alliances, the availability of raw materials and the regulatory
environment. As a result of these and other factors, Global may experience
material fluctuations in future operating results on a quarterly or annual
basis (including, to the extent appropriate governmental approvals are not
obtained, the inability to manufacture and sell products), which could
materially and adversely affect its business, financial condition, operating
results, and stock price. An investment in Global involves various risks,
including those referred to above and those which are detailed from
time-to-time in Global's other filings with the Securities and Exchange
Commission.

     These forward-looking statements speak only as of the date hereof. Global
undertakes no obligation to publicly release the results of any revisions to
these forward-looking statements which may be made to reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.


General

     Global was formed in April 1993 to acquire the manufacturing plant,
equipment and certain related assets and the ANDAs, NDAs and NADAs of Richlyn.
Richlyn operated as a generic pharmaceutical business from 1947 to 1992.
Richlyn ceased operations at this facility in 1992 as a result of failure to
comply with FDA regulations concerning cGMP.

     From its inception through 1997, Global has devoted substantially all of
its efforts to improving and renovating the facility, establishing policies and
procedures to bring the facility into compliance with cGMP, and obtaining all
government approvals necessary to begin operating the facility. In July 1997,
Global was notified that, following an inspection, FDA had determined that
Global's Tetracycline Hydrochloride 250 mg capsules had been validated. The FDA
subsequently determined that sufficient data was available to assign an
expiration date to the product's label and Global commenced operations and
began shipping the product in September 1997. Since Global commenced
operations, the FDA has routinely inspected and approved the work necessary for
each of Global's product introductions. In January 1998, the FDA informed
Global that product-by-product inspections and authorizations would no longer
be required for Global's current ANDA product portfolio. Through August 15,
1999, Global has introduced to market 21 products. See "Global's Business"
later in this joint proxy statement/prospectus.

     Global cannot currently predict whether its business will be seasonal in
nature, but to the extent that it manufactures and distributes products that
pertain to seasonal ailments such as allergies or colds, Global may experience
seasonal patterns in its sales and profitability. There can be no assurance
that the potential seasonality of Global's business will not have a material
adverse effect on Global. In addition, Global's revenues, and hence its
profitability, if any, may vary significantly from fiscal quarter to fiscal
quarter as well as in comparison to the corresponding quarter of the previous
year as a result, among other factors, of the timing of process validation for
particular generic drug products, the timing of any significant initial
shipments of newly approved drugs and competitive pressures from other generic
drug manufacturers who receive FDA approvals covering competing products.

     In August 1997, Global signed two exclusive ten-year licensing agreements
with Eurand America Inc., an international drug company that specializes in
oral delivery. Eurand is a unit of American Home Products, one of the world's
largest research-based pharmaceutical and healthcare companies. Under the first
agreement, Eurand develops, manufactures and supplies to Global several dosages
of Pancrelipase, a pancreatic enzyme used primarily by cystic fibrosis patients
to aid in digestion using a new Eurand technology, and grants Global an
exclusive license to market and sell the products in the United States subject
to minimum sales levels. The


                                       76
<PAGE>

second agreement provides for Eurand to supply Global with the existing Eurand
Pancrelipase 4500 USP Lipase content product, for the generic market; this
product is currently marketed as Lipram 4500. Another Eurand manufactured
product, Lipram 10,000, was introduced in June 1998.


     During the six months ended June 30, 1999, Global has introduced to market
its first new ANDA approval, Minocycline HCl 100mg capsule, an antibiotic,
which is the generic equivalent of Lederle's Minocin(R).


Results of Operations


     Until the quarter ended December 31, 1997, when Global became operational,
Global was considered a development stage company as defined in Statement of
Financial Accounting Standards No. 7.


     The year ended December 31, 1998 was Global's first full year of
operations with $4,401,000 in revenues. Global had an accumulated deficit of
$22,591,000 at December 31, 1998.


Six Months Ended June 30, 1999 compared to Six Months Ended June 30, 1998


     Global's net loss applicable to common stock for the six months ended June
30, 1999, was $3,020,000 as compared to a net loss of $2,347,000 in the same
period in 1998. The increase was due primarily to a non- cash charge for
imputed stock dividends of $1,474,000 in 1999 partially offset by increased
revenues and lower unabsorbed manufacturing overhead.


     The net sales for the six months ended June 30, 1999, were $4,217,000
compared to $1,918,000 in the comparable period in 1998. The increase in net
sales in 1999 was due primarily to an increase in the number of products and
customers as compared to the same period in 1998.


     The cost of sales of $3,220,000 for the six months ended June 30, 1999 had
associated cost of goods sold of $2,236,000 and an unabsorbed manufacturing
overhead of $984,000 representing the under capacity utilization of the plant
and infrastructure. For the six months ended June 30, 1998, the cost of sales
of $2,255,000 had associated cost of goods sold at $912,000 and an unabsorbed
manufacturing overhead of $1,343,000.


     The gross margin for the six months ended June 30, 1999, was $997,000
compared to a gross margin loss of ($337,000) in the six months ended June 30,
1998, due primarily to higher sales and higher absorption of manufacturing
overhead by the increased production.


     The research and development costs for the six months ended June 30, 1999
were $997,000 compared to $1,247,000 in the six months ended June 30, 1998. The
decrease in research and development expense in the six months ended June 30,
1999 was primarily due to payments of $200,000 for development costs to Eurand
America made in the six months ended June 30, 1998, but none in the comparable
period in 1999.


     The selling, general and administrative expenses were $1,524,000 for the
six months ended June 30, 1999, compared to $1,174,000 for the same period in
1998. The increase of $350,000 over 1998 was due primarily to merger-related
expenses in connection with the proposed merger with Impax and additional
selling expenses compared to the same period in 1998 including personnel,
advertising, travel and freight.


     The interest expense was $94,000 for the six months ended June 30, 1999,
compared to $39,000 for the same period of 1998, due to increased levels of
borrowings, primarily for working capital purposes.


     The interest income was $72,000 for the six months ended June 30, 1999
compared to $98,000 in the same period of 1998 due primarily to a decrease in
investments in cash equivalents in the first quarter of 1999.


     The other income was zero for the six months ended June 30, 1999, compared
to $424,000 for the six months ended June 30, 1998, which included payments of
$417,000 for the U.S. Ranitidine profit distribution from Genpharm. There were
no U.S. Ranitidine profit distributions from Genpharm in 1999.


                                       77
<PAGE>

     The other expense was zero for the six months ended June 30, 1999,
compared to $72,000 for the six months ended June 30, 1998, representing
amounts due to a sales organization for a one-time profit sharing arrangement
for the distribution of one of Global's products.


Year Ended December 31, 1998 compared to Year Ended December 31, 1997.

     Global's net loss for the year ended December 31, 1998 was $4,615,000, as
compared to a net loss of $5,877,000 for the year ended December 31, 1997. The
decrease in the net loss was due primarily to increased revenues . Also, during
1998 Global issued Series C preferred stock which resulted in non-cash imputed
dividends which increased the net loss applicable to common stock by $140,000
or $0.03 per share to $4,755,000 or $1.07 per share.

     In 1997, Global issued Series A and Series B preferred stock which
resulted in non-cash imputed dividends which increased the net loss applicable
to common stock by $2,547,000 or $0.59 per share to $8,424,000 or $1.97 per
share.

     Net sales for the year ended December 31, 1998 were $4,401,000 as compared
to $427,000 for the year ended December 31, 1997. The increase in net sales of
$3,974,000 was due primarily to an increase in number of products and customers
realized in 1998 as compared to 1997. Also, Global was operational for only
three months in 1997, as compared to a full year of operations in 1998.

     The increase in cost of goods sold in 1998 compared to 1997 was due to the
fact that operations did not commence until the fourth quarter of 1997. Cost of
sales of $4,681,000 for the year ended December 31, 1998 had associated cost of
goods sold of $2,064,000 and an unabsorbed manufacturing overhead of $2,617,000
representing the undercapacity utilization of the plant and infrastructure. For
the year ended December 31, 1997, cost of sales was $321,000.

     Research and development costs for the year ended December 31, 1998 were
$2,229,000. There were no research and development costs in 1997. The increase
in research and development costs in 1998 as compared to 1997 was primarily due
to biostudy costs for two ANDAs, development costs to Eurand and additional
personnel expenses.

     Selling, general and administrative expenses for the years ended December
31, 1998 and 1997 were $2,537,000 and $6,164,000, respectively. The decrease is
due to the significant increase in operational activity whereby certain costs
previously written off as general and administrative expenses are now allocated
to the cost of production and are reflected in cost of sales.

     Interest expense was $113,000 for the year ended December 31, 1998 as
compared to $65,000 for the year ended December 31, 1997, due to additional
borrowings from the Pennsylvania Industrial Development Authority and the
Delaware River Port Authority through the Philadelphia Industrial Development
Corporation and the short-term borrowing from the General Electric Capital
Corporation Credit Facility.

     Interest income was $137,000 for the year ended December 31, 1998 as
compared to $124,000 for the year ended December 31, 1997, due to an increase
in investments in cash equivalents resulting primarily from the proceeds of the
Series B preferred stock issuance.

     Other income of $479,000 for the year ended December 31, 1998 primarily
was comprised of $445,000 of royalties received under the Genpharm distribution
agreements. Other income of $122,000 generated during the year ended December
31, 1997 was due primarily to an amount received from a supplier for a claim
relating to unacceptable materials purchased from the supplier.

     Other expense of $72,000 for the year ended December 31, 1998 represents
costs for a nonrecurring profit sharing arrangement with a sales organization
for the distribution of one of Global's products.


Year Ended December 31, 1997 compared to Year Ended December 31, 1996.

     Global's net loss for the year ended December 31, 1997 was $5,877,000, as
compared to a net loss of $4,608,000 for the year ended December 31, 1996. The
increase in the net loss was due primarily to increased payroll costs resulting
from hiring of personnel necessary to support Global's infrastructure, recent
FDA


                                       78
<PAGE>

approvals and the "ramping up" for expected product introductions, partially
offset by minimal sales in 1997. Also, during 1997, Global issued Series A and
Series B preferred stock which resulted in non-cash imputed dividends which
increased the net loss applicable to common stock by $2,547,000 or $0.59 per
share to $8,424,000 or $1.97 per share.


     Net sales were $427,000 in the fourth quarter and for the year ended
December 31, 1997. Until the fourth quarter of 1997, Global was considered a
development stage company.


     Selling, general and administrative expenses were $6,164,000 in the year
ended December 31, 1997 as compared to $5,121,000 during the same period in
1996, due primarily to increased payroll costs resulting from the hiring of
personnel necessary to support Global's infrastructure, recent FDA approvals
and the "ramping up" for expected product introductions.


     Interest income was $124,000 for the year ended December 31, 1997 as
compared to $375,000 earned in the comparable period in 1996, due primarily to
a decrease in investments in cash equivalents throughout the year as a result
of capital expenditure incurred in upgrading the manufacturing facility, hiring
personnel necessary to support Global's infrastructure and "ramping up" for
expected product introductions.


     Interest expense was $65,000 for the year ended December 31, 1997 as
compared to interest expense of $40,000 during the same period in 1996 due to
the additional borrowings from Pennsylvania Industrial Development Authority
and the Delaware River Port Authority via Pennsylvania Industrial Development
Corporation


     Other income of $122,000 generated during the year ended December 31, 1997
was due primarily to an amount received from a supplier for a claim filed by
Global in 1996 relating to unacceptable materials purchased from the supplier.


Liquidity and Capital Resources


     Until Global's IPO, Global financed its activities primarily through the
issuance of promissory notes to the family that previously controlled Richlyn,
low interest borrowings, proceeds from the private placement of equity
securities, and loans from stockholders.


     In December 1995, Global completed its IPO in which 1,650,000 shares of
common stock were sold by Global for net proceeds of $11,489,000. An additional
247,500 shares of common stock were sold to the underwriter of the IPO in
January 1996, for net proceeds to Global of $1,835,000.


     In July 1997, Global received a $758,000 loan from PIDA bearing annual
interest of 3.75% for 15 years and a $350,000 loan from the DRPA via the PIDC
bearing annual interest of 5.00% for 10 years. These loans are secured by land,
building and building improvements. A portion of the loans funded capital
projects, with the remaining proceeds invested in interest bearing certificates
of deposit owned by Global and pledged as additional collateral.


     Global completed an initial closing of approximately $1.2 million of its
Series A preferred stock in August 1997, and a subsequent closing of $150,000
in September 1997. In addition, Global completed the closing of $5 million of
its Series B preferred stock in December 1997. In connection with these
offerings, at December 31, 1997, Global incurred aggregate expenses, of
approximately $196,000, resulting in net proceeds to Global of approximately
$6.1 million. Global used the proceeds from these offerings for working capital
purposes. All the shares of Series A and Series B preferred stock have been
converted to common stock.


     In July 1998, Global entered into a revolving credit facility with General
Electric Capital Corporation, providing financing to Global of up to $5 million
based on levels of accounts receivable and inventory. Amounts borrowed under
the credit facility bear interest, payable monthly, at the Index Rate plus 4%
per annum. The Index Rate is the latest rate for 30-day dealer placed
commercial paper published in the "Money Rates" section of The Wall Street
Journal. Global also pays a fee of .125% per annum on the unused available
portion of the credit line. At June 30, 1999, Global had outstanding borrowings
of $764,000 with additional availability of approximately $1,600,000 under the
credit line.


                                       79
<PAGE>

     In November 1998, Global issued 9,000 shares of Series C preferred stock
and a five year warrant to purchase 225,000 shares of common stock at an
initial exercise price equal to $4.00 per share, for proceeds of $900,000. The
proceeds were used for working capital purposes.


     On March 2, 1999, Global issued 30,000 shares of Series D preferred stock
and a five year warrant to purchase 375,000 shares of common stock at an
initial exercise price equal to $4.00 per share, for aggregate proceeds of
$3,000,000. On May 18, 1999, Global issued to the same investors an additional
20,000 shares of its Series D preferred stock and a five year warrant to
purchase 250,000 shares of common stock at an initial exercise price equal to
$4.00 per share, for aggregate proceeds of $2,000,000. The proceeds of this
private placement are being used for funding research and development efforts,
working capital and general corporate needs.


The Year 2000 Issue


     Global's computer system and programs were designed in recent years and
concerns related to the Year 2000 issue were addressed at the time the decision
to purchase the system was made. During 1998, management initiated a program to
prepare Global's computer systems, applications and other equipment that may
employ date sensitive embedded chips for the Year 2000. Global has been advised
by its hardware and software vendors that all databases used by current systems
are Year 2000 compliant. Global completed an inventory of all computer hardware
and software applications and successfully tested their Year 2000 compliance.
Global is in the process of addressing the Year 2000 issues with customers,
suppliers, service providers and other constituents, which is expected to be
completed shortly. Global will continue to review the information received in
response to these inquiries and to determine the need and extent of contingency
planning. During the three months ending June 30, 1999, Global contracted with
an outside firm regarding contingency support for its computer hardware system
and completed the remaining areas of its contingency planning as of October 31,
1999. At this time, Global does not believe that the Year 2000 issue represents
a material event or uncertainty or that the cost of addressing the Year 2000
issue is material to Global's business, operations or financial condition.


Risk of Global's Year 2000 Issues


     Achieving Year 2000 compliance is dependent on many factors, some of which
are not completely within Global's control. There can be no assurance that
Global will be able to identify all aspects of its business that are subject to
Year 2000 problems of customers or suppliers that affect Global's business.
There also can be no assurance that Global's software vendors are correct in
their assertions that the software is Year 2000 compliant, or that Global's
estimate of the costs of systems preparation for Year 2000 compliance will
prove ultimately to be accurate. Should either Global's internal systems or
internal systems of one or more significant suppliers or customers fail to
achieve Year 2000 compliance, or Global's estimate of the costs of becoming
Year 2000 compliant prove to be materially inaccurate, Global's business and
its results of operations could be adversely affected.


New Financial Accounting Standards


     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which established standards for reporting and display of
comprehensive income and its components in a financial statement that is
displayed with the same prominence as other financial statements. Comprehensive
income includes all changes in equity during a period from all transactions
other than those with stockholders, including net income, foreign currency
related items and unrealized gain or loss on certain securities. The
disclosures prescribed by this standard had no effect on Global for the year
ended December 31, 1998.


     Also in 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information", which established guidance for
disclosure of business segment information in annual financial statements. The
statement had no impact on Global as it operates in one business segment:
generic pharmaceuticals.


                                       80
<PAGE>

     In 1998, the FASB issued SFAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits." This standard revises and
standardizes disclosure requirements for pension and other postretirement
benefits in annual financial statements. This statement had no impact on Global
as Global has no pension or other postretirement plans which require
disclosure.

     In 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which established a new model for the
accounting and reporting of derivative and hedging transactions. The statement
amends a number of existing standards and is effective for fiscal years
beginning after June 15, 2000 (as amended by SFAS No. 137). Global is assessing
this statement, but believes it will have no impact on Global.

     Also in 1998, the AICPA issued SOP 98-1, "Accounting for Internally
Developed Software," with required adoption for most companies beginning in
1999. This SOP provides guidelines for the capitalization of certain internal
software development costs. Global adopted this standard in 1999, which had no
impact on its financial results.

Global's Business


Introduction

     Global Pharmaceutical Corporation is a specialty pharmaceutical company
engaged principally in the development, manufacture and marketing of solid oral
generic prescription drugs with primary application in smaller, niche markets.
Global is headquartered at a 113,000 square-foot, state-of-the-art research and
manufacturing facility located in Philadelphia, Pennsylvania, and is
incorporated in Delaware.

     Global was formed in April 1993 to acquire the manufacturing plant,
equipment and certain related assets and liabilities and the Abbreviated New
Drug Applications (referred to as ANDAs), New Drug Applications (referred to as
NDAs) and New Animal Drug Applications (referred to as NADAs) of Richlyn
Laboratories, Inc. Richlyn operated a generic pharmaceutical business from 1947
to 1992 when the facility was closed for failure to comply with Food and Drug
Administration regulations concerning cGMP.

     From Global's inception through 1997, Global has devoted substantially all
of its efforts to improving and renovating the facility, establishing policies
and procedures to bring the facility into compliance with cGMP, and obtaining
all government approvals necessary to begin operating the facility. In July
1997, Global was notified that, following an inspection, the FDA had determined
that Global's Tetracycline Hydrochloride 250 mg capsules had been validated.
Global commenced operations and began shipping the product in September 1997.
During the remainder of 1997, the FDA routinely inspected and approved the work
necessary for each of Global's product introductions. In January 1998, the FDA
informed Global that product-by-product inspections and authorizations would no
longer be required for its current ANDA product portfolio.

     Since the start of operations, Global has introduced to market 21
products; a table containing these products and related information is listed
in the Products and Product Development section immediately following this
introductory section.

     Global's strategic policy is to develop a broad product line, targeted at
niche markets, composed of solid oral (tablets and capsules) prescription,
generic drugs, various products that require isolation during their production,
narcotic and other drug products that are heavily regulated by the United
States Drug Enforcement Agency. In August 1997, Global received approval from
the DEA to manufacture Class II through V controlled substance products. Global
also intends to seek to develop or license certain brand-name pharmaceutical
products.

     In addition, Global intends to expand its line of generic products through
a combination of a research and development program that is expected to result
in new products owned by Global, as well as the licensing of additional
products owned by others. Generally, it is important that a new generic product
be approved by the FDA for marketing by, or shortly after, the patent
expiration date of the equivalent brand name drug (plus any legislatively
granted extensions) in order to gain significant market share at attractive
profit margins. As more generic products compete in the same market, which
customarily occurs increasingly over time following the brand name product's
patent expiration date (and extensions, if any), unit prices and profit margins
decrease. As the development of a new generic drug product, including its
formulation, testing and FDA approval, generally currently takes approximately
three or more years, development activities may begin several years in advance
of the patent expiration date of the brand-name drug equivalent. Consequently,
Global may select drugs for development several years in advance of their
anticipated entry to market. Global intends to enter larger, more competitive
generic markets at such times as it believe it can effectively compete in those
markets.

     Positioning itself to effectuate this strategy, in January 1997, Global
entered into an agreement with Genpharm, Inc., a Canadian corporation and an
indirect subsidiary of Merck KGaA, a German corporation, pursuant to which
Global agreed to supply packaging or available capacity with respect to
Genpharm's United States Ranitidine Form I production requirements based on a
five-year cost-plus and percentage-of-profits compensation arrangement,
commencing in August 1997, when Genpharm received ANDA approval for Ranitidine
from the FDA. Ranitidine is the generic equivalent of Glaxo Wellcome plc's
patented prescription drug Zantac(R). Global received and recognized as revenue
approximately $445,000 in royalties from Genpharm for the year ended December
31, 1998.


                                       82
<PAGE>

     In addition to the packaging of Ranitidine, the Genpharm agreement
provides Global with the opportunity to develop products for the U.S. market
with the assistance of Merck KgaA. During 1998, Global filed ANDA's for two
products selected under the Genpharm agreement.

     Also, in August 1997 Global signed two exclusive ten-year licensing
agreements with Eurand America, a unit of American Home Products, an
international drug company that specializes in oral drug delivery. One
agreement provides for Eurand to supply Global with a specified dosage of
Pancrelipase, a pancreatic enzyme used primarily by cystic fibrosis patients to
aid in digestion, for the generic market. The second agreement provides for
Eurand to develop and manufacture for Global, on an exclusive basis, several
Pancrelipase products using a new Eurand technology, and grants Global an
exclusive ten-year license to market and sell the products in the United States
subject to minimum sales levels. Currently, Global is marketing two products:
Lipram 4500 and Lipram 10,000.

     In July 1998, Global entered into a revolving credit facility with GE
Capital Corporation, providing funding to Global of up to $5 million based on
levels of accounts receivable and inventory. Amounts borrowed under this credit
facility bear interest, payable monthly, at the Index Rate plus 4% per annum.
The Index Rate is the latest rate for 30-day, dealer-placed commercial paper
published in the "Money Rates" section of The Wall Street Journal.

     In November 1998, Global issued 9,000 shares of Series C preferred stock
and a five-year warrant to purchase 225,000 shares of common stock at an
initial exercise price equal to $4.00 per share for proceeds of $900,000. On
March 2, 1999, Global issued 30,000 shares of Series D preferred stock and a
five-year warrant to purchase 375,000 shares of common stock at an initial
exercise price equal to $4.00 per share for aggregate proceeds of $3,000,000.
On May 18, 1999, Global issued to the same investors an additional 20,000 of
Series D preferred stock and a five-year warrant to purchase 250,000 shares of
common stock at an initial exercise price equal to $4.00 per share, for
aggregate proceeds of $2,000,000.


Products and Product Development

     Global's policy is to develop a broad product line composed of solid oral
(tablets and capsules) prescription, generic drugs and various products that
require isolation during their production. Global also intends to seek to
develop, license or acquire certain brand-name pharmaceutical products.

     Global also plans to manufacture and sell drugs that are regulated by the
DEA such as narcotics, barbiturates and certain tranquilizers, as well as
certain products that require isolated manufacturing facilities, which Global
has provided by refurbishing and equipping a part of our existing facility. DEA
regulations generally deal with the storage and dissemination of certain drugs
and related raw materials and are designed to protect the security of those
products and their dissemination against receipt by unauthorized persons.
Global believes that the DEA regulations that will be applicable to Global will
not materially increase the scope or expense of our regulatory compliance
requirements.

     Global acquired from Richlyn 54 ANDAs, NDAs and NADAs and more than 100
previously marketed prescription and over-the-counter formulations including
pharmaceutical products not subject to FDA approval that were manufactured and
sold by Richlyn. Six of these ANDAs were validated and are currently marketed.
In addition, fifteen other products were introduced to market as of August 15,
1999. The following table contains a list of the twenty-one products Global
currently markets:

     Global's current pipeline comprises two product applications awaiting FDA
approval, five non-ANDA products, one reintroduction of previously approved
ANDA products, a series of line extensions to the LIPRAM line of Pancrelipase
capsules which are licensed from Eurand and six additional products in various
stages of development which will require ANDA submissions. The current
development project with Eurand includes development of the second of the new
technologies previously licensed by Global. It is anticipated that in addition
to the line extensions this technology may also result in a lower cost of goods
for these products.


Raw Materials

     The raw materials that will be essential to Global's business are expected
to be bulk pharmaceutical chemicals which are generally available and purchased
from numerous sources. Because the FDA requires specification of raw material
suppliers in applications for approval of drug products, if raw materials from
a specified supplier were to become unavailable, the required FDA approval of a
new supplier could cause a significant delay in the manufacture of the drug
involved. Although Global expects to specify more than one raw materials
supplier with respect to each FDA application where that is possible, some
materials are currently available from only one or a limited number of
suppliers, as a result of which Global would be subject to the special risks
that are associated with limited sources of supply. Global plans to purchase
bulk pharmaceutical chemicals pursuant to multishipment contracts, typically of
one year's duration, when Global believes advance-ordered bulk purchases are
advantageous to assure availability at a specified price. Global believes that
alternative sources could be found, or new sources would arise, should any of
Global's sole or limited source raw materials become unavailable from current
suppliers. Nevertheless, any curtailment of raw materials could be accompanied
by production or other delays as well as increased raw materials costs, with
consequent adverse effects on Global's business and results of operations.
Furthermore, as any new source of raw materials, whether domestic or foreign,
would require FDA approval, any delays in obtaining FDA approval could also
have a material adverse effect on Global's business and operating results.

     Following a general trend in the pharmaceutical industry, an increasing
portion, anticipated to be a majority over time, of Global's raw material
supplies may come from foreign sources. Export and import policies of the
United States and foreign countries therefore could also materially affect the
availability and cost to Global of certain raw materials at any time or from
time to time.


Quality Control

     In connection with the manufacture of drugs, the FDA requires testing
procedures to monitor the quality of the product as well as the consistency of
its formulation. Global maintains a state-of-the-art laboratory that performs,
among other things, analytical tests and measurements required to control and
release raw materials and finished products.


                                       84
<PAGE>

     Global has established quality monitoring and testing programs and
procedures designed to assure that all critical activities associated with the
production, control and distribution of Global's drug products will be
carefully controlled and evaluated throughout the process. By following a
series of systematically organized steps and procedures, Global seeks to assure
that established quality standards will be achieved and built into the product.



     Global's policy is to continually seek to meet the highest quality
standards, with the goal of thereby assuring the quality, purity, safety and
efficacy of each of Global's drug products. Global believes that adherence to
high operational quality standards will also promote more efficient utilization
of personnel, materials and production capacity.


Sales and Marketing


     Global markets solid oral prescription pharmaceuticals primarily directed
to the generic sector of the pharmaceutical market (also known as the
"multisource pharmaceutical market"). The distribution of these products is
primarily through the traditional pharmaceutical supply channels, including,
but not limited to, National Wholesalers Drug Association wholesalers,
warehousing drug store chains, generic distributors, managed healthcare
providers, mail-order pharmacies, hospitals and institutions, governmental
agencies, and independent pharmacies.


     Presently, Global concentrates its sales and marketing efforts on the most
prolific supply-chain partners because their national presence provides access
to a greater number of customers and patients. These supply-chain partners
traditionally also support the process and help generate product demand.


     As the manufacturers of cost-effective, multisource pharmaceuticals
increased their reach and overall placement of products, customers began
relying on longer-term arrangements with suppliers. Global has entered into
several multiyear, multiproduct agreements with various customers, including
chains, managed healthcare providers, governmental agencies and group
purchasing organizations. The product requirements of these contract customers
are satisfied by utilizing the traditional pharmaceutical supply channels.


     Marketing efforts are expected to extend beyond the ordinary promotional
vehicles; Global plans to reach the decision makers, including physicians and
dispensing pharmacists, with campaigns designed to develop awareness of some of
Global's exclusive pharmaceutical alternatives. By increasing awareness of
these new generic entities, Global can provide customers a choice by offering
similar therapies at a fraction of the cost of brand-name products.


     In many ways 1998 and 1999 were transitional years for Global. By
progressing from a development stage to a fully operational company, much of
the primary focus shifted toward gaining acceptance of Global and its product
by various customers in the pharmaceutical supply channels. To that end, Global
was successful in gaining acceptance at all of the top 10 pharmaceutical
wholesalers, several of the top 10 warehousing drug store chains, managed
healthcare providers and governmental agencies, both directly and indirectly,
through contracts. Additionally, Global has successfully entered into other new
business, including two contract development projects and two contract
packaging projects. Global plans to continue to pursue this type of new
business in order to increase utilization of Global's facility and
infrastructure. There can be no assurance that Global will be successful in the
pursuit of this business.


Competition


     Competition in the generic industry is intense. Global is in competition
with numerous other companies in that industry, including major pharmaceutical
concerns and other exclusively generic manufacturers, most of whom have
significantly greater resources.


     The originator of a pharmaceutical product generally markets the product
under its own brand name during the life of the product's patent and any
statutory extensions of the patent. Companies introducing a product after the
patent (and any extension) expires may market the product under a brand name
and promote it to physicians and pharmacists to create a market for the product
or may market the product under its


                                       85
<PAGE>

generic name and rely on physicians, pharmacists and customers to specify the
lower-cost generic product. Producers of brand-name pharmaceutical products are
also involved in the generic marketplace, due to their concurrent marketing of
both generic and brand-name versions of their products after their patents have
expired.


     Some of Global's competitors may choose to augment their presence in the
generic drug market through acquisitions and strategic alliances. This activity
could result in consolidation and restructuring within the generic industry and
could impair Global's ability to compete effectively or effectively limit the
number of new opportunities for Global's products.


     The principal competitive factors in the generic pharmaceutical market are
the ability to introduce generic versions of products promptly after a patent
expires, price, quality of products, customer service (including maintenance of
inventories for timely delivery), breadth of product line and the ability to
identify and market niche products. Approvals for new products may have a
synergistic effect on a company's entire product line as orders for new
products are frequently accompanied by, or bring about, orders for other
products available from the same company. Price is usually the major
competitive factor with respect to a generic product, but as more generic
products enter a given market, their prices, and hence their profit margins,
decrease and competition increasingly is based primarily on quality of product
and service.


Proprietary Rights


     Global does not own any patents and does not believe that patent
protection is material to Global's business. Global may in the future be
required or may desire to obtain other licenses to develop, manufacture and
market commercially viable products. There can be no assurance that any
licenses, if needed or desired by Global, will be obtainable on commercially
reasonable terms or that any licensed patents or proprietary rights will be
valid and enforceable. Further, should Global become subject to any claim that
it is violating the patent rights of another person, Global could be subject to
costly litigation and, possibly, material liability. Global carefully monitors
trademarks used by pharmaceutical companies, including product trademarks,
through regularly published and readily available sources. Further, as Global's
generic products will only be manufactured and sold by Global after their
respective brand-name product patents have expired, and as Global sells its
products under generic, chemical names, Global believes the likelihood of
infringing on the patents of others is and will continue to be remote.


Government Regulation


     Industry Regulation


     All pharmaceutical manufacturers are extensively regulated by the federal
government, including the FDA, the DEA and various state agencies. The Federal
Food, Drug, and Cosmetic Act, the Controlled Substances Act, the Generic Drug
Enforcement Act of 1992 and other federal statutes and regulations govern or
influence the manufacture, labeling, testing, storage, recordkeeping, approval,
advertising and promotion of Global's products. Noncompliance with applicable
requirements can result in fines, recalls, seizure of products, suspension of
production, refusal of the government to enter into supply contracts or to
approve drug applications, and criminal prosecution.


     FDA approval is required before any "new drug" may be distributed in
interstate commerce. A drug that is the generic equivalent of a previously
approved prescription drug (i.e., the reference drug) also requires FDA
approval. Many over-the-counter drugs also require FDA pre-approval if the
over-the-counter drug is not covered by or does not conform with the conditions
specified in an applicable OTC Drug Product Monograph. All facilities engaged
in the manufacture of drug products must be registered with the FDA and are
subject to FDA inspection to ensure that drug products are manufactured in
accordance with cGMP.


     Generally, two types of applications are used to obtain FDA approval of a
new drug. They are:


   1. New Drug Application. For drug products with active ingredients or
     indications not previously approved by the FDA, a prospective manufacturer
     must submit a complete application which contains


                                       86
<PAGE>

     the results of clinical studies supporting the drug's safety and efficacy.
     These studies, progressing from Pre-Clinical through Phase III Clinical
     Testing can take from five to ten years. An NDA may also be submitted for
     a drug with a previously approved active ingredient if the abbreviated
     procedure discussed below is not available. Currently, FDA approval of an
     NDA, on average, is estimated to take approximately 24 to 26 months after
     the completion of all clinical testing.

   2. Abbreviated New Drug Application. The Drug Price Competition and Patent
     Term Restoration Act of 1984 (referred to as the "Drug Price Act")
     established an abbreviated new drug application procedure for obtaining
     FDA approval of certain generic drugs. An ANDA is similar to an NDA except
     that the FDA waives the requirement for conducting clinical studies to
     demonstrate the safety and effectiveness of the drug. Instead, for drugs
     that contain the same active ingredient and have the same route of
     administration, dosage form, strength and indication(s) as drugs already
     approved for use in the United States, the FDA ordinarily only requires
     bioavailability data illustrating that the generic drug formulation is
     bioequivalent to the previously approved reference drug. "Bioavailability"
     indicates the rate of absorption and levels of concentration of a drug in
     the blood stream which are needed to produce a therapeutic effect.
     "Bioequivalence" compares the bioavailability of one drug product with
     another and, when established, indicates that the rate of absorption and
     the levels of concentration of a generic drug in the body do not show a
     significant difference from those of the previously approved equivalent
     drug. According to information published by the FDA, it currently takes
     approximately 18 to 20 months on average to obtain FDA approval of an ANDA
     following the date of its first submission to the FDA.

     The Drug Price Act created new statutory protections for approved brand
name drugs. Prior to enactment of the Drug Price Act, the FDA gave no
consideration to the patent status of a previously approved drug in deciding
whether to approve an ANDA. Under the Drug Price Act, the effective date of
approval of an ANDA can depend, under certain circumstances, on the patent
status of the brand-name drug. Additionally, the Drug Price Act, in certain
circumstances, can extend the term of certain patents to cover a drug for up to
five additional years. Any such extension is intended to compensate the patent
holder for the reduction of the effective market life of a patent due to the
time involved in federal regulatory review. With respect to certain drugs that
are not covered by patents, the Drug Price Act sets specified time periods of
two to ten years during which ANDAs for generic drugs cannot become effective
or, under certain circumstances, be filed if the equivalent brand-name drug was
approved after December 31, 1981.

     Among the requirements for new drug approval is the requirement that the
prospective manufacturer's facility, production methods and recordkeeping
practices, among other factors, conform to cGMP. The cGMP must be followed at
all times when the approved drug is manufactured. In complying with the
standards set forth in the Good Manufacturing Practices regulations, the
manufacturer must expend time, money and effort in the areas of production and
quality control to ensure full technical compliance. Failure to comply can
result in possible FDA actions such as the suspension of manufacturing or
seizure of finished drug products. Global is also governed by federal, state
and local laws of general applicability, such as laws regulating working
conditions.

     The Generic Drug Enforcement Act of 1992 establishes penalties for
wrongdoing in connection with the development or submission of an ANDA. In
general, the FDA is authorized to temporarily bar companies or temporarily or
permanently bar individuals from submitting or assisting in the submission of
an ANDA and to temporarily deny approval and suspend applications to market
off-patent drugs under certain circumstances. In addition to debarment, the FDA
has numerous discretionary disciplinary powers, including the authority to
withdraw approval of an ANDA or to approve an ANDA under certain circumstances
and to suspend the distribution of all drugs approved or developed in
connection with certain wrongful conduct.

     Global is also subject to the Maximum Allowable Cost Regulations, which
limit reimbursements for certain multisource prescription drugs under Medicare,
Medicaid and other programs to the lowest price at which such drugs are
generally available. In many instances, only generic prescription drugs fall
within these regulations' limits. Generally, the methods of reimbursement and
fixing of reimbursement levels are under active review by federal, state and
local governmental entities as well as by private third-party reimbursers.
Global cannot predict the results of those reviews or their impact on Global's
business.


                                       87
<PAGE>

     Virtually every state as well as the District of Columbia has enacted
legislation permitting the substitution of equivalent generic prescription
drugs for brand name drugs where authorized or not prohibited by the
prescribing physician and currently 13 states mandate generic substitution in
Medicaid programs.


     Environmental Laws


     Global is subject to comprehensive federal, state and local environmental
laws, including the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, the Resource Conservation and Recovery Act
and the Toxic Substance Control Act, which govern, among other things, all
emissions, waste water discharge and solid and hazardous waste disposal, and
the remediation of contamination associated with generation, handling and
disposal activities. Global is subject periodically to environmental compliance
reviews by various regulatory offices.


     A Phase I environmental study was conducted with respect to Global's idled
plant and operations in 1993 and certain environmental compliance issues
identified at that time, including findings of asbestos in certain areas of the
plant and underground oil storage tanks, have been addressed. Additionally,
Global monitors regularly its compliance with any applicable Environmental
Laws. There can be no assurance that future developments, administrative
actions or liabilities relating to environmental matters will not have a
material adverse effect on Global's financial condition or results of
operations.


Litigation and Product Liability


     Global's operations are subject to an order issued on May 25, 1993, by the
United States District Court for the Eastern District of Pennsylvania. The
Richlyn order, among other things, permanently enjoined Richlyn from
introducing into commerce any drug manufactured, processed, packed or labeled
at Richlyn's manufacturing facility unless Richlyn met certain stipulated
conditions, including successful compliance with a validation and
recertification program as described below. Having acquired certain assets of
Richlyn, Global is obligated by the terms of the Richlyn order. The Richlyn
order also requires that Global hire and retain a person, subject to FDA
approval, who, by reason of training and expertise, is qualified to inspect
Global's drug manufacturing facilities to determine that its methods,
facilities and controls are operated and administered in compliance with cGMP.
The Richlyn order further requires that the person so retained both will
inspect Global's manufacturing facilities and Global's manner of operating them
and will examine all drug products manufactured, processed, packed and held at
Global's facility; and will certify in writing to FDA Global's compliance with
related cGMP. Global has retained an independent consultant to serve in respect
of the Richlyn order.


     Additionally, Global has assumed the liabilities of Richlyn in connection
with Diethyl Stilbestrol, which was manufactured by Richlyn and many other drug
manufacturers during the late 1950s and early 1960s. DES was prescribed to
pregnant women during that period and has been alleged to cause birth defects,
in particular an increased risk of uterine cancer and sterility to female
children whose mothers took DES during their pregnancy. There have been
numerous claims brought against drug manufacturers in connection with DES.
Since 1987, Richlyn's insurers have paid approximately $136,000 on Richlyn's
and Global's behalf to settle approximately 143 DES-related suits. Global is
unaware of any other legal actions having been brought or threatened against
Richlyn or Global in connection with DES-related claims. Global believes that
all DES-related legal actions have been directed towards individual
manufacturers and have not been embodied in a class action and, as such, Global
does not expect to be held liable for DES-related claims other than claims
based on products manufactured by Richlyn. While Richlyn's insurers have in the
past defended those DES claims against Richlyn and paid settlements in
connection therewith to date, those insurers have reserved their right to
discontinue the defense of the claims and the payment of any settlements at any
time. There can be no assurance or guarantee that the insurers will defend
actions or pay claims in the future. Further, there can be no assurance that,
if those insurers fail or refuse to pay any claim, Global will have recourse
against the insurers with respect thereto. Accordingly, there can be no
assurance that Global will not be exposed to the risk of substantial monetary
judgments. Claims settlements to date have been based upon market share, and
Richlyn's share of the market during the periods in question was substantially
less than 1%. Global does not believe the Richlyn DES liabilities will have a
material adverse effect on Global's business.


                                       88
<PAGE>

     Product liability claims by customers constitute a risk to all
pharmaceutical manufacturers. Global carries $10 million of product liability
insurance for its own manufactured products. Global believes that this
insurance will be adequate for its foreseeable purposes and is comparable to
product liability insurance carried by similar generic drug companies.

     Global is not aware of other material pending or threatened legal actions,
private or governmental, against it.


Employees

     As of October 1, 1999, Global employed approximately 76 full-time persons.
Of those employees, approximately 26 work in the quality area, 30 are in
operations, 10 are in administration, six are in product development and four
work in sales and marketing. Global may also employ part-time personnel from
time to time to meet specific demands of Global's business should they arise.
None of Global's employees are subject to collective bargaining agreements with
labor unions. Global believe that its relations with its employees, in general,
are satisfactory.


Properties

     The executive offices and research, warehouse and production facilities of
Global occupy an aggregate of approximately 113,000 square feet at Castor &
Kensington Avenues in Philadelphia, Pennsylvania. Global's principal executive
offices are part of that overall facility.

     Global owns its plant, which consists of three three-story brick
interconnected buildings that were constructed between 1900 and 1930. The
interior of the plant has been substantially renovated and modernized since
1993 and includes a new dust collection system and special environmental
control units for humidity and temperature. The land and the building serve as
partial collateral for two Pennsylvania Industrial Development Authority loans.


     Of the total 113,000 square foot area of the plant, approximately 20,000
square feet are used for warehousing and storage operations, including high
security DEA areas and designated areas for raw material, processed goods,
labels and packaging materials; approximately 11,000 square feet are devoted to
manufacturing operations; approximately 13,700 square feet for maintenance
operations; approximately 10,000 square feet for laboratory, quality assurance
and quality control activities, including batch testing and stability testing
operations; approximately 5,000 square feet for labeling and packaging
activities; approximately 2,500 square feet for product development; and
approximately 9,000 square feet are used for administrative functions. The
unused balance of the plant, approximately 41,800 square feet, is available for
future expansion.

     Global maintains an extensive equipment base, much of it new or recently
reconditioned and automated, including manufacturing equipment for the
production of tablets and capsules; packaging equipment, including fillers,
cottoners, cappers and labelers; and a well-equipped, modern laboratory. The
manufacturing equipment includes mixers and blenders for capsules and tablets,
automated capsule fillers, tablet presses, particle reduction, sifting
equipment and tablet coaters. Global also maintains a broad variety of material
handling and cleaning, maintenance and support equipment. Global owns
substantially all of its manufacturing equipment and believes that its
equipment is well maintained and suitable for its requirements.

     Global maintains property and casualty and business interruption insurance
in amounts it believes are sufficient and consistent with practices for
companies of comparable size and business.

     Barry R. Edwards has entered into a three-year employment agreement with
Global effective March 1998. Mr. Edwards' employment agreement provides for a
base annual salary of $145,000, which may be increased annually at the

incentive bonus program of up to 24% of his base salary in accordance with
pre-established individual, corporate and business goals. Other than the

1999, in each case based on Mr. Edwards' continued employment during that time.
The employment agreement grants to Mr. Edwards the position of Executive Vice

Executive Officer. In the event the merger is completed, Mr. Edwards'

was not earned in 1998.

additional year. The employment agreements of Messrs. Mendelsohn, Groenewoud
and Spiegler prohibit them from (1) competing with Global for one year
following termination of employment with Global and (2) disclosing confidential
information or trade secrets in any unauthorized manner. If one of those
employees is discharged without cause (as defined in such employee's
agreement), Global will continue to pay such employee at his then current

In conjunction with the repricing of all of Global's stock options, Mr.

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


General


     Impax was founded in late-1994 by Dr. Charles Hsiao and Dr. Larry Hsu with
a corporate mission to develop, formulate and commercialize both generic and
brand name controlled-release oral pharmaceuticals. Impax's strategy is to
utilize its proprietary drug delivery technology along with its know-how to
build a portfolio of controlled-release dosage forms and to commercialize such
new products either in partnership with pharmaceutical companies or on its own.



     Impax was originally organized on September 27, 1994, as a California
corporation (Impax Pharmaceuticals, Inc.). On September 1, 1995, Impax was
reorganized as a California limited liability company (Impax Pharmaceuticals,
LLC) and operated in this form through September 30, 1996. On October 1, 1996,
Impax reorganized once again assuming its current legal form as Impax
Pharmaceuticals, Inc., a California corporation.


     To date, Impax has filed three ANDAs with the FDA covering generic
versions of three different branded, prescription pharmaceuticals. FDA approval
for one of these products, pentoxifylline, was received in August, 1999.


     Impax currently has thirteen additional generic controlled release
products and two new controlled-release products under development. Of these
product candidates, seven are in various phases of bioequivalence studies and
eight are in formulation development.


Results of Operations


     Impax has generated no revenues to date and, from inception until June 30,
1999, accumulated a deficit of $14,909,000.


     Since inception, Impax has devoted substantially all of its efforts in
research and development, improving its facility, and establishing policies and
procedures to obtain the government approvals necessary to begin operations.
Impax is not currently operating; however, it received its first ANDA approval
in August 1999 and expects distribution of the product to begin in the fourth
quarter of 1999, although there can be no assurance that such distribution will
take place. Accordingly, Impax is considered a development-stage company as
defined in Statement of Financial Accounting Standards No. 7.


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


     Impax's net loss for the year ended December 31, 1998 was $5,222,000, as
compared to $3,608,000 for the same period in 1997. The increase in net loss
was primarily due to increased research and development activities in terms of
personnel, bio-studies materials and other expenses. Research and development
expenses for the year ended December 31, 1998 were $5,127,000, as compared to
$3,255,000 for the same period in 1997.


     During the year ended December 31, 1998, Impax earned other net income in
the amount of $565,000, as compared to $75,000 for the same period in 1997. The
increase in other income in 1998 was due to milestone payments under certain
collaborative research and development activities.


Liquidity and Capital Resources


     Impax financed its research and development activities to date through
private placements of preferred equity. The aggregate proceeds raised by Impax
and its predecessors through private placement equity financings approximate
$25 million, as follows: Impax's predecessors raised an aggregate of $3.2
million through private placements of preferred equity during 1995 and the
first quarter of 1996. An additional $5.0 million was raised through private
placements of Series C convertible preferred stock during 1996 and 1997 and the
exercise of warrants to purchase Series A convertible preferred stock during
1998.


                                      102
<PAGE>

     In March, 1999, Impax completed a private placement of 3,400,000 shares of
its Series D convertible preferred stock in exchange for aggregate proceeds of
$17,000,000. The proceeds from the private placements are expected to be used
for research and development activities, capital expenditures, working capital
and other corporate purposes.

     As of June 30, 1999, Impax had approximately $8,651,000 in cash, cash
equivalents and short-term investments.

     Impax has expended, and will continue to incur substantial additional
expenditures related to its research and development activities, its capital
expenditures and working capital requirements. The Company estimates that its
current cash resources are sufficient to fund its planned operations for a
period of approximately nine months.

     Additional funds are expected to be raised through subsequent equity or
debt financings, collaborative arrangements with corporate partners, or through
other sources. Impax's failure to obtain sufficient financing to obtain
necessary FDA and government approvals would adversely affect its cash flows
and operating and development plans.

Impax's Business


Overview

     Impax is engaged in the formulation and commercialization of specialty and
controlled-release oral pharmaceuticals utilizing Impax's proprietary and
non-proprietary drug delivery technologies. Pharmaceutical companies are
increasingly utilizing controlled-release drug delivery technologies to improve
drug therapy. Controlled-release pharmaceuticals are designed to reduce the
frequency of drug administration, improve the effectiveness of the drug
treatment, ensure greater patient compliance with the treatment regimen and
reduce side effects by releasing drug dosages at specific times and in specific
locations in the body.

     Impax is applying its patented and non-patented drug delivery technologies
initially to the development of generic versions of selected high sales volume,
controlled-release brand name pharmaceuticals. Impax has submitted ANDAs to the
FDA covering generic versions of three different branded, prescription
pharmaceuticals. The ANDA for Pentoxyfylline ER tablets was approved in August
1999. This was Impax's first ANDA approval. Impax currently has 15 additional
controlled-release products under development.

     To expedite the growth of the business and reduce Impax's overall costs,
Impax has entered into collaborative development arrangements with major
pharmaceutical companies. Impax has entered into an agreement with a major
generic drug company for the development of a generic specialty product. Under
this agreement Impax will develop a bioequivalent formulation and in return
will receive a share of any profits realized by the partner relating to the
sale of the generic specialty product.

     Impax believes that the drug delivery technologies it uses for the
development of generic controlled-release pharmaceuticals also has application
to the development of brand name controlled-release pharmaceuticals. To
commercialize this opportunity, Impax plans to work with brand name
pharmaceutical companies in two basic ways:

     o by developing controlled-release formulations of existing
       immediate-release drugs and

     o by applying its drug delivery technologies to the formulation of new
       drugs under development by these pharmaceutical companies.

     In addition to the potential for improving a drug's effectiveness, Impax
believes that its drug delivery technologies will provide pharmaceutical
companies with the opportunity to enhance the commercial value of their new
drug product candidates.

     Additionally, Impax intends to use its technology for developing branded,
controlled-release pharmaceuticals which Impax plans to market and distribute
under its own name using its own salesforce.


Need For Controlled-Release Drug Delivery Technology

     To date, most orally administered prescription pharmaceutical products
have been available only in immediate-release formulations. These formulations,
although efficacious, may at times result in unwanted side effects due to high
initial drug concentrations in the blood and may be inconvenient to patients
requiring multiple drug administrations each day. Over the last decade, new
controlled-release drug delivery technologies have been developed to eliminate
or reduce certain disadvantages of immediate-release drugs. Controlled-release
drug delivery technologies generally provide more consistent and appropriate
drug levels in the bloodstream than immediate-release dosage forms, and may
improve drug efficacy and reduce side effects by releasing drug dosages at
specific times and in specific locations in the body. These technologies also
allow for the development of more "patient-friendly" dosage forms that reduce
the frequency of drug administration, thereby offering the potential for
improved patient compliance. Controlled-release pharmaceuticals can be
especially beneficial for certain patient populations, such as the elderly, who
often require multiple medications with differing dosing regimens.


Increased Patient Compliance

     With the growth of managed care organizations, patient compliance has
become a particularly important issue. Especially in chronic treatment areas
(osteoporosis, hypertension, cholesterol management) major


                                      104
<PAGE>

pharmaceutical companies are starting to undertake large scale studies to
demonstrate that their treatment options save money for the healthcare system
by reducing surgical interventions, hospital stays and doctor visits, among
others. Controlled-release dosage forms are intended to allow patients to take
medications at reduced frequency and/or at a more convenient time.


     The market for advanced drug delivery systems is large and is growing
rapidly. Impax intends to take advantage of the business opportunity presented
by an apparent market need for drugs with a superior compliance profile by both
developing new controlled-release forms of branded drugs and by formulating
controlled-release generics.


Generic Pharmaceutical Market


     Generic pharmaceuticals are therapeutic equivalents of brand name drugs
for which patents or marketing exclusivity rights have expired. The market for
generic drugs has grown in recent years due to a number of factors, including
the expiration of patents on a number of brand name drugs with significant
revenues, the availability of an abbreviated testing and approval process, the
ability of the pharmacist to substitute generic drugs for brand name drugs and
increased acceptance of the quality of these drugs. In addition, reimbursement
trends affecting the pharmaceutical industry, including large volume
purchasers, preferred provider organizations and health maintenance
organizations, are increasing the demand for lower cost pharmaceuticals.


Impax's Proprietary Drug Delivery Technologies


     Impax is developing and applying multiple drug delivery technologies to
control the release characteristics of a variety of orally-administered drugs.
To date, Impax has developed four distinct drug delivery technologies that are
patented or for which patent applications have been filed. Impax believes that
its technologies are relatively flexible and can be modified to apply to a
variety of pharmaceutical products.


     Impax's drug delivery technologies utilize a variety of polymers and other
materials to encapsulate or entrap the active drug compound and to release the
drug at varying rates and/or at predetermined locations in the gastrointestinal
tract. In developing an appropriate drug delivery technology for a particular
drug candidate, Impax considers such factors as:


     o  the desired release rates of the drug;


     o  the physico-chemical properties of the drug;


     o  the physiology of the gastrointestinal tract and the manner in which the
        drug will be absorbed during passage through the gastrointestinal tract;
        and


     o  the effect of food on the absorption rate and transit time of the drug.


     Impax plans to utilize all applicable non-patent infringing technology in
the development of generic products in order to get products on the market as
soon as possible. In an effort to avoid any potential infringement of the
patents on brand-name drugs, Impax works very closely with outside patent
counsel throughout the entire formulation development process for each product.



     Impax has developed several proprietary controlled-release delivery
technologies covering the formulation of dosage forms with extended-release and
multiple modes of release rates. Impax has obtained one U.S. patent and has
filed two additional U.S. patent applications and various foreign patent
applications relating to its drug delivery technologies. Impax is applying
several other proprietary controlled-release drug delivery technologies in its
product development programs and continues to develop new technologies for
which it may seek patent protection. The proprietary technologies are described
below:


Timed Multiple-Action Delivery System (TMDS) -- Patent application filed.


     Among a large variety of controlled release technologies available today,
most are designed for release of one active ingredient in one release profile
(typically a zero- order or single mode release). Such a release


                                      105
<PAGE>

pattern may not be adequate for drugs in certain therapeutic categories.
Impax's proprietary delivery system allows more than one active component in a
single tablet formulation to be released in multiple profiles over time. This
innovation permits the drug to reach its therapeutic level in the bloodstream
at the most beneficial intervals and in pre-determined release modes.


Dividable Multiple-Action Delivery System (DMDS) -- Patent application filed.


     DMDS is a further improvement on Impax's Multiple Action delivery system.
The invention allows the patient/physician to adjust the dosing regimen
according to clinical needs and without compromising efficacy. With the
Dividable Multiple-Action system the patient can break the tablet in half, and
each respective portion of the tablet will achieve exactly the same release
profile as the whole tablet. In contrast, the traditional controlled-release
tablet loses its "controlled" mechanism of delivery once it is broken up.


Concentric Multiple-Particulate Delivery System (CMDS) -- Patent granted.


     One of the technical challenges in the development of multiple-particulate
dosage forms with a variety of active ingredients is to achieve an acceptable
uniformity and reproducibility of a product, ensuring that each of the
components is released at pre-determined time intervals and in a desirable
release profile. By applying its unique coating and formulation technology,
Impax has reduced to practice its proprietary Concentric Multiple-Particulate
delivery system.


Sustained-Release Liquid Delivery System (SLDS) -- Patent application in
preparation.


     The technical barriers to formulating a liquid ingredient into a
sustained-release oral dosage form have precluded the development of
controlled-release dosage forms for most liquid drugs. The technology described
in this patent application utilizes a combination of special inactive
ingredients and processes to convert a liquid active ingredient into a solid
dosage form with sustained-release properties.


Product Development


Generic Specialty And Controlled-Release Pharmaceuticals


     Impax is applying its proprietary drug delivery technologies and
formulation skills initially to the development of generic versions of selected
high sales volume, brand name pharmaceuticals, for which marketing exclusivity
or patent rights have expired or are near expiration. Impax has submitted ANDAs
to the FDA covering generic versions of three different branded, prescription
pharmaceuticals. One of the pending ANDAs, Pentoxyfylline ER tablets, was
approved in August 1999. This was Impax's first ANDA approval. Impax has 15
additional generic niche and controlled-release products under development. Of
these product candidates, seven are in various phases of bioequivalence studies
and eight are in formulation development.


Generic Pharmaceutical Development Process


     When developing generic pharmaceuticals, Impax is required to prove that
the generic product candidate will exhibit IN VIVO release characteristics
equivalent to those of the brand name pharmaceutical. For a controlled-release
pharmaceutical, the drug delivery technology utilized to replicate the release
rates of the brand name pharmaceutical must do so without infringing any valid,
unexpired patents. The process by which generic products are developed for
manufacture and sale in the U.S. may be categorized into three basic stages:


     o formulation development;


     o bioequivalence studies;


     o ANDA filing with the FDA.

                                      106
<PAGE>

     During formulation development, Impax attempts to develop its own version
of the brand name drug. In creating a formulation, Impax utilizes or adapts its
drug delivery technologies to the product candidate or develops a new drug
delivery technology for that product candidate. Impax's formulation is then
evaluated in laboratory dissolution studies to determine whether human
bioequivalence studies should be conducted.

     Once a suitable formulation has been developed, human bioequivalence
studies are conducted which compare Impax's formulation to the brand name drug.
Because bioequivalence studies can be relatively expensive to perform, Impax
often conducts a pilot bioequivalence study in which it manufactures a small
batch of its product for testing in a limited number of human subjects
(typically six to twelve). If the formulation yields a blood level profile
comparable to the brand name drug, full-scale bioequivalence studies may be
performed, which require the manufacture of at least 100,000 dosage units and
usually involves 24 or more human subjects. These studies that are typically
conducted to determine the plasma concentrations of the drug in human subjects
are under fasted and fed conditions as well as under multiple dose
administration. If successful, the studies will demonstrate that the rate and
extent of absorption of the generic version is equivalent to that of the brand
name drug. If the studies demonstrate that the blood level profiles of Impax's
product are not comparable to the brand name drug, Impax will either modify its
formulation or alter the drug delivery technology employed.

     After Impax's formulation has been shown to be bioequivalent to the brand
name drug, an ANDA is prepared for submission to the FDA. This ANDA includes
the results of the bioequivalence studies and other data such as laboratory
specifications for Impax's formulation, stability data, analytical data,
methods validation and manufacturing procedures and controls. See "--Government
Regulation."


Brand Name Controlled-Release Pharmaceuticals

     Impax believes that the drug delivery technologies it uses for the
development of generic controlled-release pharmaceuticals will also have
application to the development of brand name controlled-release
pharmaceuticals. To develop and commercialize this opportunity, Impax is
exploring possible applications for its technologies and plans to utilize
clinical research organizations and work with brand name pharmaceutical
companies in two basic ways:

     o  Developing controlled-release formulations of existing immediate-release
        drugs;

     o  Applying its drug delivery technologies to the formulation of new drugs
        under development by these pharmaceutical companies.

     The first category provides a way for drug manufacturers to either
increase or preserve the value of their existing immediate-release drugs. By
developing a controlled-release drug formulation, the pharmaceutical
manufacturer has the potential to improve drug efficacy and reduce the cost of
therapy by simplifying drug administration regimens. Additionally, by
developing a controlled-release formulation of an immediate-release drug, the
pharmaceutical manufacturer may be able to receive several additional years of
marketing exclusivity before generic equivalents may be approved. The second
category is of significant importance to pharmaceutical manufacturers because
drug candidates often require easy administration (e.g., one or two doses per
day instead of four to six) to become commercially acceptable or to develop
brand loyalty by patients and physicians. Furthermore, many new drug
candidates, such as proteins and peptides, that are developed by pharmaceutical
and biotechnology companies, are expected to require advanced drug delivery
technologies in order for these drugs to be administered in oral form instead
of by injection.


Development And Licensing Agreements

     Impax has entered into development and licensing agreements covering
generic pharmaceuticals with one U.S. and two foreign pharmaceutical companies.
Pursuant to such agreements, the licensees typically will fund the cost of
product development and will pay Impax royalties in exchange for a license to
manufacture and market the products for a specified period in a specified
territory. Management believes that such arrangements offer a variety of
benefits, including providing an additional source of funding for product
development and affording Impax the ability to have certain of its generic
controlled-release products sold through the distribution networks of these
major pharmaceutical companies. Impax may terminate a


                                      107
<PAGE>

development and licensing agreement if the licensee fails to market the
licensed product, in which case all rights revert to Impax. In October, 1997,
Impax entered into an agreement with a large multi-national pharmaceutical
company to apply one of the Impax technologies to that company's marketed brand
product in an attempt to develop a once-a-day version of that product. Under
terms of the agreement, Impax, using its proprietary Timed Multiple-Action
Delivery System, agreed to attempt to develop a new controlled-release form of
a patented product owned by this corporate partner. The formulation of this
product is completed.


Manufacturing

     Impax currently has an approximately 36,000 square foot facility, which
includes a laboratory and pilot manufacturing facility encompassing
approximately 12,000 square feet. Impax is in the preliminary stages of
converting a portion of its existing facility into a production area, which
will be used for manufacturing commercial quantities of the generic versions of
products for which ANDAs have already been filed. Impax currently has only a
limited number of personnel experienced in the commercial manufacture of
pharmaceuticals. Accordingly, before Impax commences manufacturing its product
candidates in commercial quantities, significant expenditures and additional
personnel will be required.


Competition

     The pharmaceutical industry is highly competitive and is affected by new
technologies, governmental regulations, health care legislation, availability
of financing, and other factors. Many of Impax's competitors have longer
operating histories and greater financial, marketing and other resources than
Impax.

     Impax expects that it will be subject to competition from numerous other
entities that currently operate, or intend to operate, in the pharmaceutical
industry. These include companies that are engaged in the development of
controlled-release technologies and products, as well as other pharmaceutical
manufacturers that may decide to undertake in-house development of these
products. Impax is initially concentrating its efforts on generic
controlled-release pharmaceuticals. Typically, selling prices of
immediate-release generic drugs have declined and profit margins have narrowed
after generic equivalents of brand name products are first introduced and the
number of competitive products has increased. Similarly, the maintenance of
particular levels of profitability for Impax's generic controlled-release
products will depend, in large part, on Impax's ability to introduce new
products before its competitors and on the intensity of competition with
respect to existing products.


Patents And Proprietary Rights

     Impax believes that patent and trade secret protection, particularly of
its drug delivery and formulation technologies, is important to its business
and that its future will depend in part on its ability to obtain patents,
maintain trade secret protection and operate without infringing the proprietary
rights of others.

     Impax has been issued one U.S. patent and has additional U.S. patent
applications and various foreign patent applications relating to its drug
delivery technologies. Impax expects to apply for additional U.S. and foreign
patents in the future. The issuance of a patent is not conclusive as to its
validity or as to the enforceable scope of the claims of the patent. There is
no assurance that Impax's patents or any future patents will prevent other
companies from developing similar or functionally equivalent products or from
successfully challenging the validity of Impax's patents. Furthermore, there is
no assurance that:

     o any of Impax's future processes or products will be patentable;

     o any pending or additional patents will be issued in any or all
       appropriate jurisdictions;

     o Impax's processes or products will not infringe upon the patents of
       third parties;

     o Impax will have the resources to defend against charges of infringement
       by or protect its own patent rights against third parties.

     Impax also relies on trade secrets and proprietary knowledge, which it
generally seeks to protect by confidentiality and non-disclosure agreements
with employees, consultants, licensees and pharmaceutical companies. There can
be no assurance, however, that these agreements will not be breached, that
Impax will have adequate remedies for any breach, or that Impax's trade secrets
will not otherwise become known by competitors.


                                      108
<PAGE>

     On January 8, 1998, Impax filed an application to register its trademark
"IMPAX" with the U.S. Patent and Trademark Office. (Serial No. 75/415057.) In
September 1999, Agfa-Gevaert, a Belgium corporation, filed a notice of
opposition with the U.S. Patent and Trademark Office alleging that Impax's
"IMPAX" mark is likely to cause confusion to the consumer. Impax has not yet
filed an answer to this opposition on November 1, 1999. No discovery has been
conducted in this matter.

     Impax does not believe that its use of the mark "IMPAX" will result in
confusion to the consumer. Impax's products are pharmaceuticals. The
Agfa-Gevaert's mark is used in connection with computer hardware and software,
which is used in the field of medical radiography. Impax believes that the
differences in pricing, product marketing and channels of distribution for the
different products will avoid any likelihood of confusion to the consumer.
However, the PTO may not agree with Impax, and may not allow registration of
Impax's "IMPAX" mark. If Impax is unable to register the trademark "IMPAX",
then it may no longer desire, or even be able, to use the name "Impax
Laboratories, Inc." for the combined company.

     There has been substantial litigation in the pharmaceutical, biomedical
and biotechnology industries with respect to the manufacture, use and sale of
new products that are the subject of conflicting patent rights. Most of the
brand name controlled-release products of which Impax is developing generic
versions are covered by one or more patents. Under the Waxman-Hatch amendments,
when a drug developer files an ANDA for a generic drug, and the developer
believes that an unexpired patent which has been listed with the FDA as
covering that brand name product will not be infringed by the developer's
product or is invalid or unenforceable, the developer must so certify to the
FDA. That certification must also be provided to the patent holder, who may
challenge the developer's certification of non-infringement, invalidity or
unenforceability by filing a suit for patent infringement within 45 days of the
patent holder's receipt of such certification. If the patent holder files suit,
the FDA can review and approve the ANDA, but is prevented from granting final
marketing approval of the product until a final judgment in the action has been
rendered or 30 months from the date the certification was received, whichever
is sooner. Should a patent holder commence a lawsuit with respect to alleged
patent infringement by Impax, the uncertainties inherent in patent litigation
make the outcome of such litigation difficult to predict. To date, no such
actions have been commenced against Impax, although it is anticipated that
actions may be filed as Impax files additional ANDAs. The delay in obtaining
FDA approval to market Impax's product candidates as a result of litigation, as
well as the expense of such litigation, whether or not Impax is successful
could have a material adverse effect on Impax's results of operations and
financial position.


Government Regulation

     All pharmaceutical manufacturers are subject to extensive regulation by
the federal government, principally the FDA, and, to a lesser extent, by state
and local governments. The Federal Food, Drug and Cosmetic Act (the "FDCA") and
other federal statutes and regulations govern or influence the development,
testing, manufacture, safety, labeling, storage, recordkeeping, approval,
advertising, promotion, sale and distribution of prescription pharmaceutical
products. Pharmaceutical manufacturers are also subject to certain
recordkeeping and reporting requirements, establishment registration and
product listing and FDA inspections.

     The Waxman-Hatch amendments to the FDCA established abbreviated
application procedures for obtaining FDA approval for generic versions of brand
name prescription drugs (the "Listed Drugs") that are off-patent or whose
marketing exclusivity has expired. Approval to manufacture and market generic
drugs is obtained by filing ANDAs. As a substitute for clinical studies, the
FDA requires data demonstrating that the ANDA drug formulation is bioequivalent
to a previously approved Listed Drugs, among other requirements.

     The advantage of the ANDA approval mechanism is that an ANDA applicant is
not required to conduct pre-clinical and clinical studies to demonstrate that
the product is safe and effective for its intended use. Impax has filed three
ANDAs with the FDA for generic versions of brand prescription pharmaceuticals,
and intends to file additional ANDAs to obtain approval to market its other
generic controlled-release products. No assurances exist that ANDAs will be
suitable or available for Impax's products, or that Impax's proposed products
will receive FDA approval on a timely basis, if at all.

     Patent certification requirements for generic controlled-release drugs
could also result in significant delays in obtaining FDA approvals. First,
where patents covering the Listed Drugs are alleged to be invalid,


                                      109
<PAGE>

unenforceable or not infringed, patent infringement litigation may be
instituted by the holder or holders of the brand name drug patents against
Impax. Second, the first company to file an ANDA for a given drug which is
successful in certifying that an unexpired patent covering the reference brand
name drug is invalid, unenforceable, or will not be infringed by its product,
can be awarded 180 days of market exclusivity during which the FDA may not
approve any other ANDAs for that drug. A successful certification results if
the patent owner (who must be notified of the certification) does not commence
an infringement action within 45 days of having been so notified, or, having
brought a timely infringement action, receives an adverse final court decision.



     While the Waxman-Hatch amendments codify the ANDA mechanism for generic
drugs, it also fosters pharmaceutical innovation through incentives that
include market exclusivity and patent term extension. First, the Waxman-Hatch
amendments provide two distinct market exclusivity provisions that either
preclude the submission or delay the approval of an abbreviated drug
application. A five-year marketing exclusivity period is provided for new
chemical compounds, and a three-year marketing exclusivity period is provided
for applications containing new clinical investigations essential to an
approval, such as new indications or new delivery technologies. The three-year
marketing exclusivity period would be applicable to the development of a novel
drug delivery system. The marketing exclusivity provisions apply equally to
patented and non-patented drug products.


     Second, the Waxman-Hatch amendments provide for patent term extensions to
compensate for patent protection lost due to time taken in conducting FDA
required clinical studies or during FDA review of data submissions. Patent term
extension may not exceed five additional years nor may the total period of
patent protection following FDA marketing approval be extended beyond 14 years.
In addition, by virtue of the Uruguay Round Agreements Act of 1994 that
ratified the General Agreement on Tariffs and Trade ("GATT"), certain brand
name drug patent terms have been extended to 20 years from the date of filing
of the pertinent patent application (which can be longer than the former
17-year patent term). This can further delay ANDA effective dates. Patent term
extensions may delay the ability of Impax to use its proprietary technology, in
the future, to market new extended release products, file section 505(b)(2)
NDAs referencing approved products (see below), and file ANDAs based on listed
drugs when those approved products or listed drugs have acquired patent term
extensions.


     With respect to any drug with active ingredients not previously approved
by the FDA, a prospective manufacturer must submit a full NDA, including
complete reports of pre-clinical, clinical and other studies to prove that
product's safety and efficacy for its intended use. An NDA may also need to be
submitted for a drug with a previously approved active ingredient if, among
other things, the drug will be used to treat an indication for which the drug
was not previously approved, if the method of delivery is changed or if the
abbreviated procedure discussed above is otherwise not available. A
manufacturer intending to conduct clinical trials for a new drug compound as
part of an NDA is required first to submit an investigational new drug
application ( "IND") to the FDA containing information relating to pre-clinical
and planned clinical studies. The full NDA process is expensive and time
consuming. Controlled or extended-release versions of approved
immediate-release drugs will require the filing of an NDA. The FDA will not
accept ANDAs when the delivery system or duration of drug availability differs
significantly from the listed drug. However, the FDCA provides for NDA
submissions that may rely in whole or in part on publicly available clinical
data on safety and efficacy under section 505(b)(2) of the FDCA. Impax may be
able to rely on existing publicly available safety and efficacy data in filing
NDAs for extended-release products when such data exists for an approved
immediate-release version of the same chemical entity. However, there is no
guarantee that the FDA will accept such applications under section 505(b)(2),
or that such existing data will be publicly available or useful. Further,
utilizing the section 505(b)(2)-application process is uncertain, because
neither Impax nor the FDA has had significant experience with it. Additionally,
under the Prescription Drug User Fee Act of 1992, all NDAs require the payment
of a substantial fee upon filing, and other fees must be paid annually after
approval. No assurances exist that, if approval of an NDA is required, such
approval can be obtained in a timely manner, if at all.


     Manufacturers of marketed drugs must conform to the FDA's cGMP standards
or risk sanctions such as the suspension of manufacturing or the seizure of
drug products and the refusal to approve additional


                                      110
<PAGE>

marketing applications. The FDA conducts periodic inspections to implement
these rules. Impax's manufacturing facility has been inspected by the FDA with
regard to the ANDA submissions made and the FDA has advised Impax that it was
found to be in compliance with applicable cGMP standards. An additional
inspection will be performed by the FDA to assure successful process validation
after ANDA approval and before initiation of commercial distribution of these
products. There can be no assurance that Impax's facility will be found to be
in compliance with cGMP or other regulatory requirements. Failure to comply
could result in significant delays in the development and testing of Impax's
planned products, as well as increased costs.


     Noncompliance with applicable requirements can also result in total or
partial injunctions against production and/or distribution, refusal of the
government to enter into supply contracts or to approve NDAs or ANDAs, criminal
prosecution and product recalls. The FDA also has the authority to revoke for
cause drug approvals previously granted.


     Under the Generic Drug Enforcement Act, ANDA applicants (including
officers, directors and employees) who are convicted of a crime involving
dishonest or fraudulent activity (even outside the FDA regulatory context) are
subject to debarment. Debarment is disqualification from submitting or
participating in the submission of future ANDAs for a period of years or
permanently. The Generic Drug Enforcement Act also authorizes the FDA to refuse
to accept ANDAs from any company which employs or uses the services of a
debarred individual.


     Products marketed outside the United States which are manufactured in the
United States are subject to certain FDA regulations, as well as regulations by
the country in which the products are to be sold.


     The Prescription Drug Marketing Act ("PDMA"), which amends various
sections of the FDCA, requires, among other things, state licensing of
wholesale distributors of prescription drugs under federal guidelines that
include minimum standards for storage, handling and recordkeeping. It also
requires certain wholesale distributors, including Impax, to provide to each
wholesale distributor a statement identifying each sale of the drug before the
sale to such wholesale distributor, among other requirements. It also sets
forth civil and criminal penalties for violations of these and other
provisions. Various sections of the PDMA are still being implemented by the FDA
and the states. Nevertheless, failure to comply with the wholesale distribution
provisions and other requirements of the PDMA could have a materially adverse
effect on Impax.


     Impax is governed by federal, state and local laws of general
applicability, such as laws regulating working conditions and environmental
protection. Impax is also licensed by, registered with, and subject to periodic
inspection and regulation by, the DEA and California state agencies, pursuant
to federal and state legislation relating to drugs and narcotics. Certain drugs
that Impax may develop in the future may be subject to regulations under the
Controlled Substances Act and related statutes.


Product Liability Insurance


     The design, development and manufacture of Impax's products involve an
inherent risk of product liability claims. Impax has obtained product liability
insurance that covers substantially all products marketed by Impax in its
generic drug distribution operations, as well as bioequivalence studies for
controlled-release products candidates. Impax believes that its product
liability insurance is adequate for its current operations, and will seek to
increase its coverage prior to the commercial introduction of its product
candidates. There can be no assurance that the coverage limits of Impax's
insurance will be sufficient to offset potential claims. Product liability
insurance is expensive and difficult to procure and may not be available in the
future on acceptable terms or in sufficient amounts, if available at all. A
successful claim against Impax in excess of its insurance coverage could have a
material adverse effect upon Impax's results of operations and financial
condition.


Facilities


     The executive offices, research and development, warehouse and a pilot
plan of Impax occupy an aggregate of approximately 36,000 square feet at 30831
Huntwood Avenue, Hayward, California. Impax leases its facility pursuant to a
five year lease expiring on June 30, 2002 and renewable for another three
years. Of


                                      111
<PAGE>

the total 36,000 square feet, approximately 12,000 square feet are used for
research and development, 4,000 square feet are used for administrative
functions, 5,000 square feet for warehousing and the remaining 15,000 square
feet will be available for a commercial-scale manufacturing area.


Employees

     As of October 1, 1999, Impax had approximately 40 full-time employees. Of
these employees, 32 are employed in research and development as formulation
scientists, analytical chemists and technical support staff and eight are in
administration. Impax may also employ part-time personnel from time to time to
meet specific demands of its business as they arise. None of Impax's employees
are subject to collective bargaining agreements with labor unions. Impax
believes that its relations with its employees, in general, is satisfactory.

and customary benefits. The current salaries for Dr. Hsiao and Hsu are each
$120,000 per year. Each of the employment agreements further provide that if
the executive is terminated without cause, or if executive resigns due to a
reduction in his responsibilities or a change in his reporting relationship so
that he no longer reports to the Board of Directors, then Impax will continue
to pay executive and provide his benefits package for three years following

Employee Stock Options

The 1996 Option Plan

     During September 1996, the board of directors adopted the Impax
Pharmaceuticals, Inc. 1996 Stock Option Plan (the "1996 Plan") which was
approved by Impax's stockholders on September 30, 1996. The 1996 Plan
authorizes the issuance of options to purchase up to 500,000 shares of Impax's
common stock. On May 5, 1998, the outstanding options were amended to reduce
the per share price of outstanding options to $2.50 per share and to adopt an
ascending vesting schedule.


                                      116
<PAGE>

     The 1996 Plan allows the board of directors to grant stock options from
time to time to employees, consultants, officers and directors of Impax. The
board has the power to determine at the time the option is granted whether the
option will be an incentive stock option (an option which qualifies under
Section 422 of the Internal Revenue Code of 1986) or an option which is not an
incentive stock option. Vesting provisions are determined by the board at the
time the options are granted. The option price for any option will be no less
than the fair market value of the common stock on the date the option is
granted.

     From the period of September 1996 through October 1998, Impax's Board of
Directors granted a total of 417,000 options to a total of 25 employees and
consultants. Except as disclosed below, all options have an exercise price of
$2.50 per share. In connection with the reorganization of Impax
Pharmaceuticals, LLC, Impax assumed options granted under the Impax
Pharmaceuticals, LLC option plan for an aggregate of 18,000 shares which have
an exercise price of $1.00 per share. Additionally, Dr. Hsiao received an
option on April 12, 1999 to purchase 100,000 shares of common stock at any
exercise price of $2.75 per share.

The 1999 Equity Incentive Plan


     During April 1999, the board of directors adopted the Impax
Pharmaceuticals, Inc. 1999 Equity Incentive Plan (the "1999 Pre-Merger Plan")
which was approved by Impax's stockholders during a special meeting of the
stockholders on March 22, 1999. The 1999 Pre-Merger Plan reserves for issuance
1,000,000 shares of Impax's common stock for issuance pursuant to stock option
grants, stock grants and restricted stock purchase agreements.

     The 1999 Pre-Merger Plan allows the board of directors to grant stock
options or bonuses from time to time to employees, consultants, officers and
directors of Impax. The board has the power to determine at the time the option
is granted whether the option will be an incentive stock option (an option
which qualifies under Section 422 of the Internal Revenue Code of 1986) or an
option which is not an incentive stock option. Vesting provisions are
determined by the board at the time each particular stock award is granted. The
price for any stock award will be no less than the fair market value of the
common stock on the date the stock award is granted.

     From the period of April 1999 through July 1999, Impax's Board of
Directors granted a total of 251,100 options to a total of 30 employees and
consultants. To date, all options granted have an exercise price of $2.50 per
share, except with respect to the option granted to Dr. Hsiao and described
below.

     On April 2, 1999, Charles Hsiao, Ph.D. was granted an option to purchase

Certain Transactions of Impax

Impax Acquisitions

     Impax is the successor corporation to two previous California entities.
The reorganization history of Impax and its predecessors is described below.
The original entity was incorporated in California under the same name, Impax
Pharmaceuticals, Inc. on September 27, 1994. On June 6, 1995, Impax
Pharmaceuticals, LLC, a California limited liability company, acquired all of
the assets, and assumed all of the liabilities, of the former Impax
Pharmaceuticals, Inc. in a tax-free reorganization. As part of the
reorganization, the shareholders of the former Impax Pharmaceuticals, Inc. were
issued units in Impax Pharmaceuticals, LLC in the same ownership percentage
(and with comparable rights and privileges) as they held in the predecessor
corporation.

     On or about September 30, 1996, Impax Pharmaceuticals, Inc., the currently
existing California corporation, acquired all of the assets, and assumed all of
the liabilities, of Impax Pharmaceuticals, LLC in a tax-free reorganization. As
part of the reorganization, the shareholders of Impax Pharmaceuticals, LLC were
issued stock in the currently existing Impax in the same ownership percentages
(and with comparable rights and privileges) as they held in the predecessor
corporations.

Anti-Dilution Protection to Series C Preferred Stock.

     In the first quarter of 1999, Chemical Company of Malaysia purchased
800,000 shares of Series D preferred stock of Impax. In order to induce
Chemical Company of Malaysia to make such an investment, Impax agreed to amend
its Articles of Incorporation to adjust the ratio at which Series C preferred
stock converts into common stock of Impax from the existing 1:1 ratio to a
ratio of 1.7534:1.

Cross Licensing Agreement.


     On September 30, 1996, Impax and Chemical Company of Malaysia entered into
a cross licensing agreement. This agreement grants Chemical Company of Malaysia
a right of first refusal to exclusively manufacture and sell each of Impax's
products in certain Southeast Asian countries. For each product that Chemical
Company of Malaysia accepts such a right of first refusal, it will pay a
royalty to Impax ranging from 3% to 5% of net revenues from such product,
depending on the aggregate revenues generated from such product in any year.
The cross licensing agreement also grants Impax a right of first refusal to
exclusively manufacture and market each of Chemical Company of Malaysia's
pharmaceutical products in Mexico, Canada and U.S., in exchange for royalty
payments ranging from 3% to 5%, depending upon the aggregate revenues generated
from such product in any year. To date, no activity has generated any royalty
payment rights or obligations for either party.

Convertible Promissory Notes and Warrants.

     In fourth quarter 1994, Impax issued promissory notes convertible into
Impax Series A preferred stock at a conversion price of $1.00 per share and

     Each of the above referenced notes and warrants were assumed by Impax
Pharmaceuticals, LLC, a California limited liability company in connection with
the tax-free reorganization in mid-1995. On October 1, 1995, the promissory
notes for John Hsiao and Richard Hsiao were paid in full by conversion of the
outstanding amounts of $100,000 and $15,000, respectively into 100,000 and
15,000 shares of Series A Preferred Stock. Those promissory notes were
thereafter canceled.

     The two remaining notes and the four warrants were subsequently assumed in
September 1996, by Impax in connection with the acquisition by Impax of all of
the assets of Impax Pharmaceuticals, LLC. On September 30, 1996, the
then-outstanding principal due under the promissory notes for Drs. Hsiao and
Hsu were converted into 399,818 and 61,819 shares of Series A preferred stock,
respectively. On June 30, 1998, the remaining outstanding balance due under the
promissory notes for Drs. Hsiao and Hsu were paid in full by conversion into
100,182 and 38,181 shares of Series A preferred stock, respectively. The two
promissory notes were then canceled.

     On October 1, 1998, each of Dr. Hsiao, Dr. Hsu, John Hsiao and Richard
Hsiao fully exercised their warrants in the amounts indicated above.


                     TRANSACTIONS BETWEEN GLOBAL AND IMPAX

     On August 11, 1999, Global and Impax entered into a Packaging Agreement
and an Exclusive Marketing Agreement relating to Impax's ANDA for
Pentoxyfylline Extended Release tablets. The Packaging Agreement provides that
Global will package all of the tablets produced by Impax, subject to compliance
with the FDA's cGMP and all other federal, state and local laws and
regulations. Global will be paid $7,600 for each batch of 8,000 units of 100
tablets and $1,600 for each batch of 800 units of 1,000 tablets. The agreement
may be terminated at any time by either party upon 180 days' written notice.
The agreement may also be terminated if the FDA revokes its approval of the
product or if the other party breaches a material term of the agreement.

     Pursuant to the Exclusive Marketing Agreement, Impax has given Global the
exclusive rights to market, sell and distribute Pentoxyfylline Extended Release
tablets throughout the United States and Canada for an initial period of three
years from the date of the agreement. The agreement is renewable for additional
one-year terms and may be terminated upon the same terms as the Packaging
Agreement. Global will pay Impax 70% of the net profits which Global realizes
from the sale of the tablets. Net profits are determined by a formula set forth
in the Exclusive Marketing Agreement.

Board Observers

     Pursuant to the merger agreement, each of Global and Impax has the right
to designate one person as a board observer of the combined company. Global has
selected Philip R. Chapman as its board observer and Impax has selected Tan Soo
Bin as its board observer.


Committees of the Board

     The board of directors of the combined company will have an executive
committee, an audit committee, a compensation committee and a stock option
committee. The members of the various committees will be appointed by the board
after the effective date of the merger.

     The executive committee will have all the powers of the board of directors
except that it will not be authorized to amend the certificate of incorporation
of the combined company, declare any dividends or issue shares of capital
stock.

     The audit committee will review with the combined company's independent
accountants the scope and timing of their audit services, any other services
they are asked to perform, the report of independent accountants on the
combined company's financial statements following completion of their audit and
the combined company's policies and procedures with respect to internal
accounting and financial controls. In addition, the audit committee will make
an annual recommendation to the board of directors concerning the appointment
of independent accountants for the ensuing year.

     The compensation committee will review and make recommendations to the
board of directors regarding the compensation and benefits of all officers of
the combined company and will review general policy matters relating to
compensation and benefits of employees of the combined company.

     The stock option committee will review the stock option benefits of all
officers of the combined company and other participants in the stock option
plans of the combined company, including the 1999 Equity Incentive Plan. The
stock option committee will also review general policy matters relating to
stock options, grant stock options to officers of the combined company and
other participants in the stock option plans of the combined company and
administer the 1999 Equity Incentive Plan.


Director Compensation

     Members of the board of directors of the combined company will not receive
any annual compensation for acting in their capacity as members of the board of
directors. We anticipate that we will pay our non-employee directors $500 for
each attended meeting of the board of directors. We also intend to grant each
non-employee director pursuant to the 1999 Equity Incentive Plan, options to
purchase 2,000 shares of stock annually. We also anticipate granting Nigel
Fleming and the second mutually agreed upon board member (when first selected)
additional options pursuant to the 1999 Equity Incentive Plan to purchase
10,000 shares upon the closing of the merger. All of these options will vest
ratably over three years commencing on the first anniversary of the grant date,
and will be exercisable at the fair market value on the date of grant. The
combined company will reimburse its directors and board observers for their
respective out-of-pocket expenses incurred in attending board and committee
meetings.


Executive Compensation

     At the effective time of the merger, it is expected that the employment
agreements of Barry Edwards with Global and of Charles Hsiao and Larry Hsu with
Impax will terminate and each of them will enter into a new employment
agreement with the combined company.


Employment Agreements of the Combined Company

     It is a condition to the closing of the merger that each of Mr. Edwards,
and Drs. Hsiao and Hsu enter into a new employment agreement with the combined
company. Each of these employment agreements is expected to be on substantially
the same terms. Mr. Edward's and Dr. Hsiao's agreements will provide that they
will serve as Co-Chief Executive Officers of the combined company and, in the
case of Dr. Hsiao, Chairman of the Board. Dr. Hsu's agreement will provide that
he will serve as President and Chief Operating Officer of the combined company.
The other material terms of these employment agreements are described below.


                                      122
<PAGE>


     Each employment agreement will be for an initial term of three years, and
will be renewed automatically for successive one-year terms unless terminated
by either party at least six months prior to the expiration of the initial term
or any renewal term. Each of the executives will receive an annual salary of
$175,000, and will be entitled to a bonus based on criteria established by the
board of the combined company. Any bonus paid to one of these three executives
must be similarly paid at the same time to the other two executives.

     Any of the executives may be terminated by the combined company, either
with or without cause. The executive may terminate his own employment for any
reason, or for good reason. These terms are defined more fully in the
employment agreements. In general, cause means:

     o a material breach of the provisions of the employment agreement relating
       to proprietary information, trade secrets, confidentiality and
       non-competition;

     o a material breach of any other provision of the employment agreement that
       is not remedied within 30 days of such breach;

     o any act of fraud or embezzlement against the combined company; or

     o any indictment of the executive for a felony or other crime that would
       cause injury to the reputation of the combined company.

In general, good reason means:

     o assignment of duties or a reduction in duties which is inconsistent with
       the executive's position;

     o a material reduction in executive's salary or benefits not agreed to by
       the executive;

     o a relocation that would require executive to have a commute of more than
       50 miles; or

     o a change in control of the combined company.

In general, a change in control is defined as:

     o the acquisition by any person or entity of ownership or control of more
       than 50% of the voting power of the combined company;

     o a sale or disposition of assets totaling more than 50% of the value of
       the combined company;

     o a merger or reorganization in which the combined company's stockholders
       immediately prior to the merger do not own at least 51% of the voting
       power of the company after the merger;

     o any transaction where the combined company's stockholders immediately
       prior to the transaction do not own at least 51% of the voting power of
       the company after the transaction; or

     o any other transaction that the board determines would materially alter
       the structure, ownership or control of the combined company.

     If the executive is terminated without cause or terminates his employment
for good reason, he will be entitled to receive a payment of all accrued and
unpaid salary and benefits plus salary and benefits for the next six months or,
if less, the remainder of the term of the employment agreement.




                                      123
<PAGE>

     The executives have also agreed to keep all proprietary information of the
combined company confidential and to assign all proprietary information or
intellectual property developed by the executive during the course of his
employment to the combined company. Each executive has also agreed that during
the term of the employment agreement and for a period of two years following
the termination of his employment, he will not engage in a business competitive
with that of the combined company or entice any of the combined company's
employees to leave the employ of the combined company or entice any of the
combined company's customers, suppliers or business partners to end their
relationship with the combined company.

     In addition to the terms previously described, Mr. Edwards' employment
agreement provides that he will receive an option to purchase 270,000 shares of
common stock at the prevailing market price at the time the option is granted.
It is expected that the option will be granted immediately after the merger is
completed. Global's Board of Directors, Mr. Edwards and certain persons who are
a majority of the individuals designated to become directors of the combined
company have agreed that Mr. Edwards will not receive any additional stock
options for the next three years. The shares covered by this option vest and
become exercisable on the following schedule: (i) first year -- 0%; (ii) second
year -- 10%; (iii) third year -- 40%; (iv) fourth year -- 50%.


Impax Laboratories, Inc. 1999 Equity Incentive Plan


     The board of directors of Global unanimously adopted, subject to approval
of the merger proposal by Global's stockholders, the Impax Laboratories, Inc.
1999 Equity Incentive Plan, referred to in this joint proxy
statement/prospectus as the "1999 Equity Incentive Plan." The board of
directors believes that approval of the 1999 Equity Incentive Plan will serve
the best interests of the combined company and its stockholders by permitting
the combined company to establish a flexible vehicle through which the combined
company can offer equity-based compensation incentives to eligible personnel
with a view toward promoting the long-term financial success of the combined
company and enhancing stockholder value. The primary features of the plan are
summarized below. The full text of the plan is set forth in Annex G to this
joint proxy statement/prospectus and the following discussion is qualified in
its entirety by reference thereto.

     The 1999 Equity Incentive Plan authorizes the grant of stock options,
stock appreciation rights, (commonly known as SARs), and stock bonus awards to
any member of the combined company's board of directors, any officer or other
employee of the combined company or its affiliates or any consultant who
performs or will perform services for the combined company or its affiliates.
In addition, each non-employee director of the combined company will receive an
automatic grant of a stock option to purchase 2,000 shares of common stock
under the plan upon his or her commencement of service as a non-employee
director of the combined company and each non-employee director will also
receive an automatic annual grant of a stock option to purchase 2,000 shares of
common stock on the day following each annual meeting of stockholders of the
combined company that occurs at least one year after his or her commencement of
service as a non-employee director. These annual grants vest ratably over a
three year period.


     Subject to adjustment to reflect stock dividends and other capital
changes, the maximum number of shares of common stock which may be issued under
the 1999 Equity Incentive Plan is 2,400,000 shares. Shares subject to awards
under the 1999 Equity Incentive Plan that are canceled, expired, terminated,
forfeited, settled in cash or withheld to satisfy the applicable purchase price
or tax withholding obligations shall again be available for issuance under the
1999 Equity Incentive Plan.

     Shares of common stock available for issuance under the 1999 Equity
Incentive Plan may be either authorized and unissued or held by the combined
company in its treasury. If the merger proposal is approved by the Global
stockholders at the special meeting, the 1999 Equity Incentive Plan will be
effective as of the closing of the merger and will, unless terminated earlier
by the board of directors, terminate on the tenth anniversary of that date.


     Subject to adjustment to reflect stock dividends and other capital
changes, the maximum number of shares of common stock with respect to which
stock options or SARs may be granted under the 1999 Equity Incentive Plan to
any employee for any calendar year will be 300,000 shares.


                                      124
<PAGE>


     The 1999 Equity Incentive Plan will, except with respect to awards to
non-employee directors, be administered by the compensation committee of the
board, consisting of at least two directors appointed by and serving at the
pleasure of the board of directors or by the board of directors itself. Subject
to the provisions of the 1999 Equity Incentive Plan, and except with respect to
awards to non-employee directors, the compensation committee will have the
authority to grant awards under the 1999 Equity Incentive Plan, to interpret
the provisions of the plan, to fix and interpret the provisions of agreements
governing awards made under the plan, to supervise the administration of the
plan, and to take such other actions as may be necessary or desirable in order
to carry out the provisions of the plan. The plan will be administered by the
board of directors with respect to awards to non-employee directors.

     Pursuant to his employment agreement, Barry R. Edwards will receive an
option to purchase 270,000 shares of common stock at the prevailing market price
at the time the option is granted. It is expected that the option will be
granted immediately after consummation of the merger. We also anticipate
granting Nigel Fleming and the second mutually agreed upon board member options
pursuant to the 1999 Equity Incentive Plan to purchase 12,000 shares upon the
closing of the merger or when first elected, as applicable. All of these options
will vest ratably over three years commencing on the first anniversary of the
grant date, and will be exercisable at the fair market value on the date of
grant. Other than with respect to these options expected to be granted to Mr.
Edwards and these outside directors, as well as the automatic annual option
grants made to non-employee directors (as described below), it is not possible
at this time to determine who may be selected to receive future awards under the
1999 Equity Incentive Plan or the number of shares subject to such awards in the
future.

STOCK OPTIONS GRANTED OR TO BE GRANTED TO THE CEO AND THE FOUR OTHER MOST
HIGHLY COMPENSATED EXECUTIVE OFFICERS AND THE NON-EMPLOYEE DIRECTORS IF THE
MERGER PROPOSAL INCLUDING THE 1999 IMPAX LABORATORIES, INC. EQUITY INCENTIVE
PLAN, IS APPROVED

(1) The exercise price per stock option is expected to be, in all instances,
    the closing price of the Global common stock on the date of grant. The
    non-employee directors options vest and become exercisable in equal
    increments on the first three anniversaries of the date of grant.


Discretionary Stock Option and SAR Awards

     Under the 1999 Equity Incentive Plan, the compensation committee may grant
stock options that are intended to qualify as "incentive stock options" within
the meaning of Section 422 of the Internal Revenue Code (commonly known as
ISOs) and stock options which do not qualify as incentive stock options
(commonly known as NQSOs). ISOs may only be granted to employees of the
combined company or its affiliates that qualify as "subsidiaries" within the
meaning of Section 424 of the Code.

     The exercise price for shares covered by an ISO may not be less than 100%
of the fair market value of the common stock on the date of grant (or, in the
case of a grant to an employee who is a "10% stockholder" of the combined
company or certain subsidiaries, 110% of the fair market value). The exercise
price for shares covered by a NQSO may not be less than the par value of the
common stock on the date of grant.

     All options will, unless sooner terminated, expire ten years (or, in the
case of an incentive stock option granted to a 10% stockholder, five years)
from the date of grant. The compensation committee has the discretion to
determine the vesting and other restrictions on the exercise of an option
and/or upon the disposition of stock acquired upon the exercise of an option.
Payment for shares acquired upon the exercise of an option may be made (as
determined by the compensation committee) in cash and/or such other form of
payment as may be permitted under the option agreement. The compensation
committee may grant replacement options to certain individuals who used
previously-owned shares to pay the exercise price of their options.


                                      125
<PAGE>


     The committee may award SARs, which entitle the holder, upon exercise, to
receive an amount, in cash or shares of common stock or a combination thereof
(as determined by the compensation committee) determined with reference to the
appreciation, if any, in the fair market value of common stock during the
period beginning on the date the SAR is granted and ending on the date the SAR
is exercised. SARs may be awarded in conjunction with or independent of any
stock option award. SARs granted in conjunction with a stock option award are
exercisable only at the same time and to the same extent as the related option
is exercisable and may only be exercised when the fair market value of the
common stock to which it relates exceeds the option exercise price.

     The 1999 Equity Incentive Plan generally provides that, unless otherwise
determined by the compensation committee, following a participant's termination
of employment or service:

   o for any reason other than the death or disability, the participant will
     have 30 days to exercise all then exercisable options or SARs; and

   o as the result of death or disability, the participant (or his or her
     beneficiary) will have one year to exercise all then exercisable options
     or SARs;

provided that, in each instance, no options or SARs may be exercised beyond the
expiration of its stated term.


Stock Bonus Awards

     The 1999 Equity Incentive Plan allows the compensation committee to grant
stock bonus awards in consideration for past services actually rendered to the
combined company or its affiliates on such terms and conditions it deems
appropriate. Shares subject to a stock bonus awards may, but need not, be
subject to a vesting schedule. Generally, unless otherwise determined by the
compensation committee, any unvested shares of common stock received pursuant
to a stock bonus award shall be forfeited upon a participant's termination of
employment or service with the combined company or its affiliates.


Non-Employee Director Automatic Stock Option Awards

     Under the 1999 Equity Incentive Plan, each non-employee director of the
combined company will be automatically granted a NQSO to purchase 2,000 shares
of common stock upon his or her commencement of service as a non-employee
director of the combined company. In addition, each non-employee director of
the combined company will automatically be granted a NQSO to purchase 2,000
shares of common stock under the plan on the day following each annual meeting
of stockholders of the combined company that occurs at least one year after his
or her commencement of service as a non-employee director of the combined
company. The options will have a ten-year term and an exercise price equal to
the fair market value of the common stock on the date of grant. The options
granted upon a non-employee director's commencement of service will vest as to
one-third on each anniversary of the date of grant, provided that the director
remains in service during the vesting period. The options granted to
non-employee directors on an annual basis will generally become one-third
vested on each of the first three anniversaries of the grant date.


Federal Income Tax Consequences relating to Options

     An optionee will not recognize taxable income upon the grant of an option.
The holder of a NQSO will generally recognize ordinary income upon the exercise
of the option in an amount equal to the excess of the fair market value of the
common stock over the exercise price (i.e., the option spread), and the
combined company will receive a corresponding deduction, subject to the
deduction limitation under Section 162(m) of the Internal Revenue Code. Upon a
later sale of the common stock, the optionee will recognize capital gain or
loss equal to the difference between the sale price and the sum of the exercise
price plus the amount of ordinary income recognized on exercise.




                                      126
<PAGE>



     The holder of an ISO will not recognize taxable income upon the grant or
exercise of the option (although, upon exercise, the option spread is
includable as income for purposes of the alternative minimum tax). If the
common stock acquired upon exercise of an ISO is sold or otherwise disposed of
within two years from the option grant date or within one year from the
exercise date, then, in general, gain realized on the sale is treated as
ordinary income to the extent of the ordinary income that would have been
realized upon exercise if the option had been a NQSO, and the combined company
will receive a corresponding deduction, subject to the deduction limitation of
Section 162(m) of the Internal Revenue Code. Any remaining gain is treated as
capital gain. If the common stock is held for at least two years from the grant
date and one year from the exercise date and the optionee is employed by the
combined company or certain subsidiaries at all times beginning on the grant
date and ending on the date three months (or, in the case of disability, one
year) prior to the exercise date, then all gain or loss recognized upon the
sale will be capital gain or loss and the combined company will not be entitled
to a deduction. A special basis adjustment applies to reduce the gain for
alternative minimum tax purposes.

                            STOCK EXCHANGE LISTING

     It is a condition to the merger that the shares of combined company common
stock to be issued in the merger be approved for listing on the Nasdaq Small Cap
Market. The combined company intends to apply for, to the extent appropriate,
its common stock to be traded on the Nasdaq National Market after the merger is
completed.


                     FEDERAL SECURITIES LAWS CONSEQUENCES:
                     STOCK TRANSFER RESTRICTION AGREEMENTS

     This joint proxy statement/prospectus does not cover any resales of shares
of the combined company common stock received by Impax stockholders, and no
person is authorized to use this joint proxy statement/prospectus in connection
with any such resale.

     All shares of the combined company common stock received by Impax
shareholders in the merger will be freely transferable, except that, shares of
the combined company common stock received by people who are considered to be
"affiliates" (as that term is defined under the Securities Act of 1933) of Impax
prior to the merger may be resold by them only in transactions permitted by the
resale provisions of Rule 144 or 145 promulgated under the Securities Act of
1933 or as otherwise permitted under the Securities Act of 1933. Generally,
people who may be deemed to be affiliates of Impax include individuals or
entities that control, are controlled by, or are under common control with,
Impax and may include officers, directors and principal shareholders of Impax.
The merger agreement requires Impax to use reasonable efforts to cause its
affiliates to execute a written agreement to the effect that such people will
not offer or sell or otherwise dispose of any of the shares of the combined
company common stock issued to such people in the merger in violation of the
Securities Act of 1933 or the rules and regulations of the Securities and
Exchange Commission.

     In addition, we have agreed to use all reasonable efforts to cause our
respective affiliates to execute written agreements prohibiting their
transferring Impax common stock or Global common stock (and combined company
common stock subsequent to the merger) during the period commencing 30 days
prior to the date the merger becomes effective and ending when financial
results covering at least 30 days of the combined company's operations have
been published.


                                    EXPERTS

     The financial statements of Global as of December 31, 1998 and 1997 and
for each of the three years in the period ended December 31, 1998 and the
financial statements of Impax as of December 31, 1998 and for each of the two
years in the period ended December 31, 1998 included in this joint proxy
statement/prospectus have been so included in reliance on the reports of
PricewaterhouseCoopers LLP, independent accountants, given on the authority of
said firm as experts in auditing and accounting.


                                 LEGAL MATTERS

     The validity of the combined company common stock to be issued in
connection with the merger will be passed upon by Fulbright & Jaworski L.L.P.

     Laurie A. Miller, who has provided legal advice to Impax and serves as its
secretary, beneficially owns, as of October 1, 1999, 15,000 shares of Series A
preferred stock of Impax, and options to purchase 22,000 shares of Impax common
stock, exercisable at $2.50 per share. As a result of and at the closing of the
merger, these securities will be converted into 50,037 shares of Global common
stock and options to purchase 73,387 shares of common stock at a price of $0.75
per share. In addition, Ms. Miller may be deemed to beneficially own 3,936,244
shares of common stock in her capacity as trustee of the Chiin Hsiao Children
Irrevocable Trust and the Hsu Children Irrevocable Trust. Ms. Miller disclaims
beneficial ownership of these shares.

                       GLOBAL PHARMACEUTICAL CORPORATION

                         NOTES TO FINANCIAL STATEMENTS

                               Six Months Ended
                        June 30, 1999 and June 30, 1998

     Note 1: The financial statements included herein have been prepared by the
Company, without audit, pursuant to the rules and regulations of the Securities
and Exchange Commission. Certain information and disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations; however, the Company believes that the disclosures are adequate to
make the information presented not misleading. It is suggested that these
financial statements be read in conjunction with the financial statements and
the notes thereto included in the Company's latest annual report on Form
10-KSB. The results of operations for the six months ended June 30, 1999, are
not necessarily indicative of the results of operations expected for the year
ending December 31, 1999.

     In the opinion of management, the information contained in this report
reflects all adjustments necessary, which are of a normal recurring nature, to
present fairly the results for the interim periods presented.

     The Company has adopted the provisions of SFAS No. 130, "Reporting
Comprehensive Income". The Company's comprehensive income (loss) for the six
months ended June 30, 1998 and 1999 is equal to its net loss for each period as
presented in the statement of operations.

     Note 2: In March 1999, the Company issued 30,000 shares of Series D
Convertible Preferred Stock for aggregate proceeds of $3,000,000. After the
Company's stockholders authorized additional shares of common stock in May
1999, the Company issued 20,000 additional shares of Series D Convertible
Preferred Stock for aggregate proceeds of $2,000,000. In connection with these
transactions, the Company issued 775,000 five-year warrants at an initial
exercise price of $4.00. The fair value of the warrants, using the
Black-Scholes option pricing model, of $712,000 plus other issuance costs of
$293,000 were deducted from the gross proceeds. The difference between the net
proceeds and the Series D Preferred Stock at its liquidation value was
recognized as an imputed Preferred Stock dividend of $1,005,000 in the period
ended June 30, 1999, as from the date of issuance, the holders of Series D
Preferred Stock, at their option, are entitled to redeem any or all shares of
the preferred stock upon the occurrence of certain events, including: 1) a sale
of all or substantially all of the Company's operating assets; 2) the Company
becomes insolvent; 3) the Company goes private; or 4) a business combination
involving the Company in which the shareholders of the Company cease to own 50%
of the voting power of all classes of stock or 50% of the total equity
securities in the new entity.


     At the option of the holder, each share of Series D Preferred Stock is
convertible into that number of shares of the Company's common stock as is
determined by dividing the liquidation value of $100 per share by the
conversion price. The conversion price is the lower of $2.00 per share or the
average closing sale price of the common stock for the five trading days
immediately preceding conversion. The difference between the $2.00 per share
conversion price and the market value of the common stock on the dates of the
issuance of Series D Preferred Stock was recognized as a Preferred Stock
dividend of $469,000 in the six months ended June 30, 1999.

     Note 3: On July 26, 1999, the Company entered into a definitive merger
agreement with Impax Pharmaceuticals, Inc. ("Impax"), a privately held drug
delivery company located in Hayward, California. Under the terms of the
agreement, Global will acquire all of Impax's outstanding stock in exchange for
an aggregate of 31,571,274 shares of Global's common stock and preferred stock.
This transaction will be accounted for as reverse acquisition under the
purchase method of accounting with Impax deemed the acquirer. The merger is
expected to be completed in the fourth quarter of 1999, subject to approval by
stockholders and regulatory agencies, and customary closing conditions.

operations, of changes in stockholders' equity (deficit) and of cash flows
present fairly, in all material respects, the financial position of Global
Pharmaceutical Corporation (the Company) at December 31, 1998 and 1997, and the
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                       GLOBAL PHARMACEUTICAL CORPORATION

                         NOTES TO FINANCIAL STATEMENTS


1. Formation and Operation of the Company

  Purpose

     Global Pharmaceutical Corporation (the "Company") was formed in April 1993
to acquire the manufacturing plant, equipment and certain related assets and
liabilities (the "Facility") and the Abbreviated New Drug Applications
("ANDAs"), New Drug Applications ("NDAs") and New Animal Drug Applications
("NADAs") of Richlyn Laboratories, Inc. ("Richlyn"). Richlyn operated a generic
pharmaceutical business from 1947 to 1992; operations of the Facility had been
idled since September 1992 for failure to comply with Food and Drug
Administration ("FDA") regulations concerning current Good Manufacturing
Practices ("cGMP").

     From its inception through 1997, the Company devoted substantially all of
its efforts to improving and renovating the Facility, establishing policies and
procedures to bring the Facility into compliance with cGMP, and obtaining all
government approvals necessary to begin operating the Facility. On July 11,
1997 the Company was notified that, following an inspection, FDA had determined
that Global's Tetracycline Hydrochloride 250 mg capsules had been validated.
The FDA subsequently determined that sufficient data was available to assign an
expiration date to the product's label and the Company commenced operations and
began shipping the product in September 1997. Since Global commenced
operations, the FDA has routinely inspected and approved the work necessary for
each of Global's product introductions. On January 29, 1998, the FDA informed
the Company that product-by-product inspections and authorizations would no
longer be required for the Company's current ANDA product portfolio. As of
March 2, 1999, the Company is shipping twenty products.

     The Company was considered a development stage company as defined in
Statement of Financial Accounting Standards No. 7 until the fourth quarter of
1997 when the Company determined it had begun operations.


  Funding of Activities

     To date, the Company has funded its efforts to engage in the manufacture,
repackaging and sale of solid oral prescription and over-the-counter generic
drugs and dietary supplements through equity and debt financings.

     In 1995, the Company completed its Initial Public Offer of Common Stock
("IPO") in which 1,650,000 shares of common stock were sold for net proceeds to
the Company of $11,488,000. In connection with the IPO, the underwriter
received an option to purchase up to 247,500 shares of common stock at $8.50
per share (the "over-allotment"). The underwriter exercised this option in
January 1996, at which time the Company sold 247,500 shares of common stock for
net proceeds of $1,835,000.

     In 1997, the Company received a $758,000 loan from the Pennsylvania
Industrial Development Authority ("PIDA") at 3.75% annually fixed for 15 years
and a $350,000 loan from the Delaware River Port Authority ("DRPA") via the
Pennsylvania Industrial Development Corporation ("PIDC") at 5.00% annually
fixed for 10 years. These loans were partially used to fund capital projects,
and are secured by land, building and building improvements. From these
proceeds, at December 31, 1998, $684,000 is invested in interest bearing
certificates of deposit owned by the Company and pledged as additional
collateral for these loans.

     The Company completed closings of $6,335,000 of its Series A and B
mandatorily redeemable convertible Preferred Stock in 1997 and $900,000 of its
Series C mandatorily redeemable convertible Preferred Stock in November 1998.

     Also in 1998, the Company entered into a three year revolving credit
facility with GE Capital, providing funding to the Company of up to $5 million
based on levels of accounts receivable and inventory. At December 31, 1998, the
Company had outstanding borrowings of $804,000 on this facility, with $373,000
of availability.

                       GLOBAL PHARMACEUTICAL CORPORATION

                 NOTES TO FINANCIAL STATEMENTS  -- (Continued)


1. Formation and Operation of the Company  -- (Continued)

     On March 2, 1999, the Company completed an initial closing of $3,000,000
of its Series D Mandatorily Redeemable Convertible Preferred Stock to Fleming
US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P.
(collectively "Flemings") (Note 14). An additional $2,000,000 of its Series D
Mandatorily Redeemable Convertible Preferred Stock to Flemings is expected to
close no later than June 30, 1999, subject to the Company's stockholders
authorization of additional shares of common stock. The Company has adequate
financing for its 1999 operational plan, even if the Company does not receive
Stockholders' approval for additional shares of common stock.


2. Summary of Significant Accounting Policies


  Cash and cash equivalents


     Cash and cash equivalents are stated at cost which approximates market
value. Cash equivalents include only securities having a maturity of three
months or less at the time of purchase.


  Concentration of credit risk


     Financial instruments which potentially subject the Company to
concentrations of credit risk are cash, cash equivalents, investments, and
accounts receivable. The Company limits its credit risk associated with cash,
cash equivalents and investments by placing its investments with highly rated
money market funds, U.S. Government securities, treasury bills and short-term
commercial paper. The Company limits its credit risk with respect to accounts
receivable by performing ongoing credit evaluations and, when deemed necessary,
requiring letters of credit, guarantees, or collateral.


     The Company has two customers which account for 38% of total sales for the
year ended December 31, 1998. At December 31, 1998, accounts receivable from
three customers represent 41% of total trade receivables. Approximately 47% of
the Company's net sales were attributable to one product family which is
supplied by a vendor under an exclusive licensing agreement.


  Inventories


     Inventories are stated at the lower of cost (determined on the basis of
first-in, first-out) or market. The Company considers product costs as
inventory once the Company receives FDA approval to market the related
products.


  Property, plant and equipment


     Property, plant and equipment are recorded at cost. Maintenance and
repairs are charged to expense as incurred and costs of improvements and
renewals are capitalized. Costs incurred in connection with the construction or
major renovation of facilities, including interest directly related to such
projects, are capitalized as construction in progress. Depreciation is
recognized using the straight-line method based on the estimated useful lives
of the related assets.


  Intangible assets


     Intangible assets are comprised of ANDAs, NDAs and NADAs acquired from
Richlyn and are recorded at fair value. Amortization is recognized on a
straight-line basis over a five year period starting on October 1, 1997, when
operations commenced.


     The Company complies with Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of". Accordingly, the carrying value of long-lived assets
and certain identifiable intangible assets are evaluated whenever changes in
circumstances indicate the carrying amount of such assets may not be
recoverable. In performing such review

                 NOTES TO FINANCIAL STATEMENTS  -- (Continued)


2. Summary of Significant Accounting Policies  -- (Continued)

for recoverability, the Company compares expected future cash flows to the
carrying value of long-lived assets and identifiable intangibles. If the
expected future cash flows (undiscounted) are less than the carrying amount of
such assets, the Company recognizes an impairment loss for the difference
between the carrying amount of the assets and their estimated fair value.

  Deferred financing costs

     Deferred financing costs are amortized on a straight-line basis over the
terms of the respective debt instrument.

  Investments

     The Company's investments in other than cash equivalents are classified as
"held-to-maturity" based upon the nature of the investments, their ultimate
maturity date, the restrictions imposed by the PIDA and PIDC loan agreements
dated July 29, 1997 (See Note 8) and management's intention with respect to
holding these securities. Realized gains and losses are determined on the basis
of specific identification of the securities sold. At December 31, 1998, the
cost of the Company's investments approximate fair value.

  Revenue recognition

     Revenues, net of applicable allowances, from product sales are recognized
upon shipment of product. Royalties are recognized when the related contract
provisions are met.

  Income taxes

     The Company utilizes the liability method of accounting for income taxes
as set forth in Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes". Under this method, deferred tax liabilities and
assets are recognized for the expected future tax consequences of temporary
differences between the carrying amounts and the tax bases of assets and
liabilities. Valuation allowances are provided on deferred tax assets for which
it is more likely than not that some portion or all of the deferred tax asset
will not be realized.

  Earnings per share

     The Company reports both basic earnings per share, which is based on the
weighted-average number of common shares outstanding, and diluted earnings per
share, which is based on the weighted average number of common shares
outstanding and all dilutive potential common shares outstanding. Because the
Company had net losses in each of the years presented, only the weighted
average of common shares outstanding have been used to calculate both basic
earnings per share and diluted earnings per share as the inclusion of the
potential common shares would be anti-dilutive. Stock options to purchase
635,997 shares in 1998 and 436,800 shares in 1997 and mandatorily redeemable
convertible preferred stock of 63,535 shares in 1998 and 63,350 shares in 1997
were outstanding but were not included in the calculation of diluted earnings
per share as their effect would be anti-dilutive.

  Accounting for stock-based compensation

     The Company has elected to disclose the fair value of stock options and
other stock-based compensation issued to employees as a pro forma effect on net
income in the footnotes to the Company's financial statements rather than as
compensation expense in the Statement of Operations.

  Accounting estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and
disclosure of contingencies at the date of the financial statements and the
reported expenses during the reporting period. Differences from those estimates
are recorded in the period they become known.

  Business segments

     The Company operates in one business segment, and has one group of
products, generic pharmaceuticals.

     The Company's revenues are derived from, and its assets are located in,
the United States.

3. Related Party Transactions

     On November 8, 1995, the Company entered into an agreement ( the "Genpharm
Agreement") with Genpharm, Inc., a Canadian corporation ("Genpharm"), an
indirect subsidiary of Merck KGaA under which Merck KGaA purchased 150,000
shares of the Company's common stock. The Company also issued to Merck KGaA a
warrant to purchase 100,000 shares of common stock at an exercise price of
$2.00 per share, (the "A Warrant") and additional warrants to purchase up to
700,000 shares, at an exercise price of $8.50 per share (the IPO price per
share), whose exercise is contingent upon the gross profit (as defined in the
agreement), if any, earned by the Company under the Genpharm Agreement. In
January 1997, the Company revised its agreement with Genpharm, pursuant to
which the Company shall supply packaging, or has supplied capacity available,
with respect to Genpharm's United States Ranitidine production requirements
based on a five-year cost-plus and percentage of profits compensation
arrangement following the receipt of the requisite FDA Ranitidine approvals. In
addition to the packaging of Ranitidine, the Genpharm Agreement provides the
Company with the opportunity to develop products with the assistance of Merck
KGaA that are marketed outside the U.S. During 1998, the Company filed ANDA's
for two products previously selected.

     The Company received and recognized as revenue approximately $445,000 in
royalties from Genpharm for the year ended December 31, 1998 which is included
in Other Operating Income in the accompanying Statement of Operations.

Rebates and chargebacks include reserves for price rebate programs for certain
products, chargebacks from wholesalers, and certain sales related items.
Accrued rebates and chargebacks at December 31, 1998 and 1997 represent
management's estimate of the Company's future obligation.


7. Income Taxes


     Due to the Company's losses since inception, no provision for income taxes
is recorded for any period. The difference between the federal statutory tax
rate and the Company's effective income tax rate is attributable to losses and
future tax deductions for which valuation allowances have been established.


The net deferred tax balance is comprised of the tax effects of cumulative
temporary differences, as follows:

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

     Due to historical losses incurred by the Company and limitations on the
future use of net operating losses due to changes in the Company's ownership, a
full valuation allowance for net deferred tax assets has been provided. If the
Company achieves profitability, certain of these net deferred tax assets would
be available to offset future income taxes.


     The tax effects of net operating loss carryforwards expire as follows:



  2010 .........   $   68

7.  Income Taxes  -- (Continued)

     Deferred start-up and organization expenditures are amortized over a
60-month period ending 2003. Net operating losses created will expire over a
20-year period.

     Under the Tax Reform Act of 1986, the amounts of and benefits from net
operating loss carryforwards may be impaired or limited in certain
circumstances. Events which cause limitations in the amount of net operating
losses that the company may utilize in any one year include, but are not
limited to, a cumulative ownership change of more than 50%, as defined, over a
three year period.

8. Notes Payable

     In July 1998, the Company entered into a three year revolving credit
facility with G.E. Capital, providing funding to the Company up to $5 million
based on the levels of accounts receivable and inventory. Amounts borrowed
under this credit facility bear interest, payable monthly, at the Index Rate
plus 4% per annum. The Index Rate is the latest rate for 30-day dealer placed
commercial paper published in the "Money Rates" section of The Wall Street
Journal. The Company also pays a fee of .125% per annum on the unused available
portion of the credit line. At December 31, 1998, the Company had borrowings of
$804,000 under this facility with $373,000 of availability.

10.  Mandatorily Redeemable Convertible Preferred Stock


     The Company has authorized 2,000,000 shares of preferred stock, $.01 par
value per share (the "Preferred Stock"). The Company issued 72,350 shares of
Preferred Stock of which 63,535 and 63,350 were outstanding at December 31,
1998 and 1997, respectively, and are classified as Mandatorily Redeemable
Preferred Stock. The remaining authorized but unissued shares could be issued
with or without mandatorily redeemable features.


     The Company's Board of Directors authorized and designated 60,000, 50,000,
9,000 and 50,000 shares of Preferred Stock as Series A Preferred, Series B
Preferred, Series C Preferred and Series D Preferred, respectively, with all
shares priced at $100 per share. In 1997, the Company issued 13,350 shares of
Series A and 50,000 shares of Series B Preferred Stock to accredited investors
for 1,335,000 and $5,000,000, respectively.


     At the option of the holder, each share of Series A Preferred and Series B
Preferred Stock is convertible into that number of shares of the Company's
common stock as is determined by dividing the liquidation value of $100 per
share by the conversion price. At December 31, 1998, the conversion price was
the lower of $2.75 per share or the average closing sale price of the common
stock for the five trading days immediately preceding conversion but in no
event less than $2.00 per share. The difference between the $2.75 per share
conversion price and the market value of the common stock on the dates of the
issuance of Preferred Stock was recognized as a Preferred Stock dividend of
$2,547,000 in 1997.


     In November 1998, the Company issued 9,000 shares of Series C Preferred
Stock and a five year warrant to purchase 225,000 shares of common stock at an
initial exercise price equal to $4.00 per share for proceeds of $900,000. The
Company allocated these proceeds by determining the fair value of the warrants
as being $140,000 using the Black-Scholes option-pricing model, with $760,000,
being allocated to Preferred Stock. The Company then recognized a $140,000
Preferred Stock Dividend to reflect the Series C Preferred Stock at its
liquidation value.


     At the option of the holder, each share of Series C Preferred Stock is
convertible into that number of shares of the Company's common stock as is
determined by dividing the liquidation value by the conversion price. The
conversion price is the lower of $2.00 per share or the average closing sale
price of the common stock for the five trading days immediately preceding
conversion but in no event less than $0.75 per share. In the event the Company,
within eighteen months from the Series C Preferred Stock initial closing,
issues and sells not less than an aggregate of $1 million of additional shares
of common stock (or securities convertible into common stock) for a
consideration per share of common stock of less than $2.00 the conversion price
will be reduced to a price equal to the consideration per share for which the
additional shares are sold.


     Except as required by law, holders of the shares of Series A , Series B,
Series C and Series D Preferred Stock vote on an as-converted basis, as a
single class with all other stockholders of the Company. Holders of Series D
Preferred also have certain voting rights with respect to major corporate
transactions or reorganization.


     Each share of Preferred Stock is entitled to a liquidation preference
equal to $100 per share before any distributions to holders of common stock,
and Series A, B, C and D Preferred Stock are not entitled to dividends unless
declared on common stock. The holders of Series C and Series D Preferred Stock
are entitled to a liquidation preference over the holders of Series A Preferred
and Series B Preferred Stock. From the date of issuance, the holders of Series
A, Series B, Series C and Series D Preferred Stock, at their option, are
entitled to redeem any or all shares of the preferred stock upon the occurrence
of certain events, including: 1) a sale of all or substantially all of the
Company's operating assets; 2) the Company becomes insolvent; 3) the Company
goes private; or 4) a business combination involving the Company in which the
shareholders of the Company cease to own 50% of the voting power of all
classes of stock or 50% of the total equity securities in the new entity.


     The Company has the option to redeem outstanding shares of the Preferred
Stock by paying the liquidation value for each share, provided that the closing
sale price of the common stock is seven dollars or more per share in the case
of Series C Preferred Stock and at least five times the conversion price, in
the case of Series D Preferred Stock, for a consecutive twenty day trading
period. Each holder of Preferred Stock shall

be entitled to redeem any or all shares in the event that the Company breaches
or fails to comply with its obligations under the respective Certificates of
Designations or the Stock Purchase Agreements, to the extent that the breach or
failure is material to or had a material adverse effect on the Company, and is
not cured within thirty days.

11.  Stockholders' Equity (Deficit)

  Common Stock

     In 1995, the Company completed its IPO in which 1,650,000 shares of common
stock were sold for net proceeds to the Company of $11,488,000. In connection
with the IPO, the underwriter received an option to purchase up to 247,500
shares of common stock at $8.50 per share. The underwriter exercised this
option in January 1996, at which time the Company sold 247,500 shares of common
stock for net proceeds of $1,835,000.

     During 1998, 2,070 shares of Series A Preferred Stock and 6,745 shares of
Series B Preferred Stock were converted into 90,544 shares and 278,682 shares
of common stock, respectively. The conversion price ranged from $2.00 to $2.75
per share. Through March 2, 1999, the remaining 11,280 and 43,255 shares of
Series A and Series B Preferred Stock were converted to common stock (Note 14).


12. Stock Options

     The Company's 1995 Stock Incentive Plan was adopted by the Company's Board
of Directors for the purpose of securing for the Company and its stockholders
the benefits arising from the ownership of Company stock options by
non-employee directors and key employees who are expected to contribute to the
Company's future growth and success.

     In December 1997, the Company's Board of Directors approved the repricing
of 426,800 outstanding options to $3.125 per share, the market value of common
stock on that date. As a result, all outstanding options were effectively
rescinded and reissued at an exercise price of $3.125 per share. No
compensation expense was recognized as a result of the repricing as the
exercise price was equal to the market price on the date of reissue. Options
vest over a three to four year period and have a maximum term of ten years. The
weighted average fair value of options granted during 1998, 1997 and 1996 was
$2.15, $2.03 and $3.37, respectively. The fair value of each option was
estimated on the date of grant using the Black-Scholes option-pricing model
with the following assumptions: (i) no expected dividend yield in 1998, 1997
and 1996, (ii) expected stock price volatility of 72.36%, 50% and 30% in 1998,
1997 and 1996 respectively, (iii) weighted average risk free interest rate of
5.33%, 5.89% and 6% in 1998, 1997 and 1996, respectively, and (iv) expected
life of options of five years in 1998, 1997 and 1996.

13. Commitments and Contingencies


  Richlyn Order


     The Company is in compliance with a May 25, 1993 order, which was entered
by the United States District Court for the Eastern District of Pennsylvania
(the "Richlyn Order"). The Richlyn Order, among other things, permanently
enjoined Richlyn from introducing into commerce any drug manufactured,
processed, packed or labeled at its manufacturing facility unless it met
certain stipulated conditions. The Company, as a purchaser of the Richlyn
facility, remains obligated by the terms of the Richlyn Order. After the
merger, the combined company will continue to be subject to the court order.
The order requires, in part, that FDA find that products manufactured,
processed and packed at the Richlyn facility conform with FDA regulations
concerning cGMP before the products can be marketed. Global was informed in
January 1998 that product by product inspection was no longer required for
Global to manufacture and sell products.

     The order against Richlyn also requires that Global hire and retain a
person, subject to FDA approval, who is qualified to inspect its drug
manufacturing facilities to determine that its methods, facilities and controls
are operated and administered in compliance with cGMP. This person must examine
all drug products manufactured, processed, packed and held at Global's facility
and certify in writing to the FDA Global's compliance with related cGMP.

  Product liability and insurance

     The Company assumed the liabilities of Richlyn in connection with Diethyl
Stilbestrol ("DES"), which was manufactured by Richlyn during the late 1950's
and early 1960's. DES was prescribed to pregnant women during that period and
has been alleged to cause birth defects. There have been numerous claims
brought against drug manufacturers in connection with DES. Since 1987,
Richlyn's insurers have paid approximately $136,000 on Richlyn's and the
Company's behalf to settle approximately 143 DES-related suits. While Richlyn's
insurers have in the past defended those DES claims against Richlyn and paid
all settlements in connection therewith to date, the insurers have reserved
their right to discontinue the defense of the claims and the payment of
settlements at any time. Claims settlements to date have been based upon market
share, and Richlyn's share of the market during the periods in question was
less than 1%. While there can be no assurance as to the ultimate resolution of
these matters, in the opinion of Management, based on the advice of legal
counsel, the ultimate liabilities resulting from such lawsuits and claims will
not materially adversely affect the financial position, operating results or
cash flow of the Company.


  Eurand America Agreement

     The Company is committed to payments of $100,000 for the development and
supply of product batches necessary for clinical studies under the license and
supply agreement entered into with Eurand America in

1997 to develop a gastro-protected pancrelipase product, subject to Eurand's
performance in accordance with terms and conditions of the agreement. Annual
minimum royalty payments will also become payable upon shipment of the product.
The Company has $100,000 and $41,000 accrued for milestone payments and royalty
payments, respectively, at December 31, 1998.

14. Subsequent Events

     From January 1, 1999 through March 2, 1999, 11,280 and 43,255 shares of
Series A and Series B Preferred Stock with liquidation values of $1,128,000 and
$4,326,000, respectively, were converted into 2,598,000 shares of Common Stock
at conversion prices ranging from $2.00 to $2.24 per share.

     On March 2, 1999, the Company issued 30,000 shares of Mandatorily
Redeemable Convertible Series D Preferred Stock and a five year warrant to
purchase 375,000 shares of common stock at an initial exercise price equal to
$4.00 per share for aggregate proceeds of $3,000,000. The Company has
determined the fair value of the warrants as being $322,500, using the
Black-Scholes option pricing model, and the fair value of the Preferred Stock
as being $2,677,500. In the first quarter of fiscal 1999, the Company will
recognize a $322,500 Preferred Stock dividend to reflect the Series D Preferred
Stock at its liquidation value. An additional $2,000,000 of its Series D
Preferred Stock is expected to be issued to the same investors prior to June
30, 1999 subject to the Company's stockholders authorization of additional
shares of common stock.

     At the option of the holder, each share of Series D Preferred Stock is
convertible into that number of shares of the Company's common stock as is
determined by dividing the liquidation value by the conversion price. The
conversion price is the lower of $2.00 per share or $1.20 per share if the
second closing of Series D Preferred Stock does not occur by June 30, 1999. The
difference between the conversion price and the market value of the common
stock on the date of the issuance of Preferred Stock will be recognized as a
Preferred Stock dividend of $281,000 in the first quarter of fiscal 1999. In
the event the Company, within eighteen months from the Series D initial
closing, issues and sells not less than an aggregate of $1 million of
additional shares of common stock (or securities convertible into common stock)
for a consideration per share of less than $2.00, the conversion price will be
reduced to a price equal to the consideration per share for which additional
shares are sold.

     At the option of the investors, the Company will pay liquidation value to
the investors if the following occur: 1) a sale of all or substantially all of
the Company's operating assets, 2) the Company becomes insolvent, 3) the
Company goes private, or 4) a business combination involving the Company in
which the shareholders of the Company cease to own 50% of the voting power of
all classes of stock or 50% of the total equity securities in the new entity.
Subject to certain specified exceptions, the holders of Series D Preferred
Stock have the preemptive right to maintain current ownership of the Company in
future equity offerings.

                          IMPAX PHARMACEUTICALS, INC.
                     (A COMPANY IN THE DEVELOPMENT STAGE)
                         NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1998 AND 1997

NOTE 1 -- THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Nature of operations

     Impax Pharmaceuticals, Inc. is engaged in the development of generic and
branded pharmaceutical products. The Company is currently in a research and
development phase with its first product expected to receive Food and Drug
Administration ("FDA") approval in 1999. The Company's revenue to date has come
from certain licensing and joint development agreements but remains
insignificant in relation to the Company's total operations. Accordingly, the
Company is considered a development stage company as defined in Statement of
Financial Accounting Standards (SFAS) No. 7.

Organization and history

     The Company was originally organized on September 27, 1994 as a California
corporation (Impax Pharmaceuticals, Inc.). Actual operations commenced in the
first quarter of 1995. On September 1, 1995, the Company was reorganized as a
California limited liability company (Impax Pharmaceuticals, LLC) and operated
in this form through September 30, 1996. On October 1, 1996, the Company
reorganized once again assuming its current legal form as Impax
Pharmaceuticals, Inc., a California corporation.

Funding of activities

     To date, the Company has funded its research and development efforts
entirely through equity financing. This includes $12,539,743 raised through
December 31, 1998 and an additional $12,700,000 raised in the first quarter of
1999.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Basis of presentation

     Certain statements including the cumulative statement of operations, the
cumulative statement of cash flows and the statement of shareholders' equity,
include activity of the Company's predecessor entities, Impax Pharmaceuticals,
Inc., and/or Impax Pharmaceuticals, LLC (See Note 1). The activity of these
predecessor entities is included in these financial statements in order to
present the history of a development stage company from its inception as
required by SFAS No. 7.

Use of estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

Cash and cash equivalents

     For purposes of the statement of cash flows, the Company considers all
short-term debt securities purchased with a maturity of three months or less to
be cash equivalents.

Short-term investments

     The Company classifies all short-term investments as available-for-sale in
accordance with Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities." The Company
places its short-term investments primarily in treasury bills. At December 31,
1998, there were no short-term investments.

Concentration of credit risk and other risks and uncertainties

     Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash, cash equivalents and short-term
investments. Products developed by the Company may require approvals


                                      F-28

                         NOTES TO FINANCIAL STATEMENTS
             YEARS ENDED DECEMBER 31, 1998 AND 1997 -- (Continued)


NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:  -- (Continued)

or clearances from the Food and Drug Administration ("FDA") or other
international regulatory agencies prior to commercialized sales. There can be
no assurance that the Company's products will receive any of the required
approvals or clearances. If the Company was denied approval or clearance or
such approval was delayed, it may have a material adverse impact on the
Company.

Property and equipment

     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets,
generally five to seven years, or the lease term of the respective assets.

Long-lived assets

     The Company evaluates the recoverability of its long-lived assets in
accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed of". SFAS 121 requires
recognition of impairment of long-lived assets in the event the net book value
of such assets exceeds the future undiscounted cash flows attributable to such
assets.

Other income

     The Company has contracts in which it performs research and development on
behalf of third parties. Under the terms of the contracts, the Company receives
milestone payments from those third parties and recognizes these payments as
other income upon completion of the specified milestone.

Income taxes

     The Company utilizes the liability method of accounting for income taxes
as set forth in SFAS No. 109, "Accounting for Income Taxes." Under this method,
deferred tax liabilities and assets are recognized for the expected future tax
consequences of temporary differences between the carrying amounts and the tax
basis of assets and liabilities. Valuation allowances are provided on deferred
tax assets for which it is more likely than not that some portion or all will
not be realized.

Stock-based compensation

     The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and complies with the disclosure
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation".

Comprehensive income

     The Company has adopted the provisions of SFAS No. 130, "Reporting
Comprehensive Income". This statement establishes standards for the reporting
and display of comprehensive income and its components. Comprehensive income is
defined to include all changes in equity during a period except those resulting
from investments by owner and distributions to owners. Since inception, the
Company has not had significant transactions that are required to be reported
in other comprehensive income. Comprehensive income (loss) for each period
presented is equal to the net loss for each period as presented in the
Statements of Operations.

Business segments

     The Company operates in one business segment, the pharmaceutical industry.


Computation of basic and diluted net loss per share

     The Company adopted SFAS No. 128, "Earnings Per Share" and the Securities
and Exchange Commission Staff Accounting Bulletin No. 98 ("SAB No. 98")
effective December 31, 1997. Accordingly, all prior periods have been restated.
Basic and diluted net loss per share are computed using the weighted average
number of shares of common stock outstanding. No additional shares are
considered to be outstanding for either computation under the provisions of SAB
No. 98.

             YEARS ENDED DECEMBER 31, 1998 AND 1997 -- (Continued)


NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:  -- (Continued)

     Stock options to purchase 286,500 shares of common stock at prices ranging
from $1.00 to $8.77 per share were outstanding at December 31, 1998, but were
not included in the computation of diluted net loss per share because they
anti-dilutive. The Company had 2,510,000 shares of convertible Preferred Stock
outstanding at December 31, 1998, which were excluded in the computation of
diluted net loss per share as they were anti-dilutive. Warrants to purchase
520,000 shares of common stock at $2.50 per share were outstanding at 1998 but
were not included in the computation of diluted net loss per share because they
were anti-dilutive. The aforementioned stock options, preferred stock and
warrants could potentially dilute earnings per share in future.

Recent accounting pronouncements

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivatives
and Hedging Activities". This statement establishes accounting and reporting
standards of derivative instruments, including certain derivative instruments
embedded in other contracts and for hedging activities. SFAS No. 133 will be
effective for the year beginning January 1, 2001. The adoption of SFAS No. 133
is not expected to have a material effect on the Company's results of
operations, financial position or cash flows.

             YEARS ENDED DECEMBER 31, 1998 AND 1997 -- (Continued)


NOTE 5 -- RELATED PARTY TRANSACTIONS:

     The Company was advanced $373,000 in fiscal 1998 from certain
shareholders. A total amount of $293,000 was repaid prior to year end and the
remaining balance was paid in January 1999.

     As of December 31, 1998, the Company had accrued $520,000 of compensation
payable to four key employees in recognition of past services rendered. The
amount is due at the Company's discretion on or before November 1, 2001.

     As of December 31, 1998, the Company had $93,000 payable to a related
party, one of the Company's Board Members, for commissions due from assisting
the Company obtaining equity financing.

     In April 1997, the Company paid $150,000 for a 15% interest in, and loaned
an additional $100,000 to, a California pharmaceutical research and development
company. As part of its investment, the Company is entitled to certain
exclusive licensing rights. The investment has been accounted for as purchased
research and development and has been expensed. The loan is unlikely to be
repaid and has been written off to general and administrative expenses.

NOTE 6 -- INCOME TAXES:

     No provision for income taxes is recorded for any period due to the
Company's losses during the development stage. The difference between the
federal statutory tax rate and the Company's effective income tax rate is
attributable to losses and future tax deductions for which no tax benefits have
been recognized.

     Deferred tax assets consist of the following (in thousands):

     Due to historical losses incurred by the Company, a full valuation
allowance for net deferred tax assets has been provided. If the Company
achieves profitability, certain of these net deferred tax assets would be
available to offset future income taxes.

     Under the Tax Reform Act of 1986, the amounts of and benefits from net
operating loss carryforwards may be impaired or limited in certain
circumstances. Events which cause limitations in the amount of net operating
losses that the Company may utilize in any one year include, but are not
limited to, a cumulative ownership change of more than 50%, as defined, over a
three year period.

NOTE 7 -- BORROWINGS:

Revolving credit note

     The Company had revolving credit notes with four of the Company's
shareholders. These facilities originally allowed for total borrowings of
$715,000 and bear interest at 7% per annum. During 1997 and the first six
months of 1998 there was $138,000 available under these facilities. At June 30,
1998 the $138,000 was borrowed and shortly thereafter the facilities were
cancelled. All of the borrowings were converted into Series A preferred stock.
In addition, the Company issued 715,000 warrants to purchase preferred stock in
connection with these facilities (see Note 9)

NOTE 8 -- COMMITMENTS:

Leases

     The Company leases office space under a noncancelable operating lease that
expires in 2002. Rent expense for the year ended December 31, 1997 and 1998 was
$132,000 and $165,000, respectively. The terms of the facility lease provide
for rental payments on a graduated scale. The Company recognizes rent expense
on a straight-line basis over the lease period, and has accrued for rent
expense incurred but not paid.

     Future minimum lease payments under the noncancelable operating lease are

NOTE 9 -- SHAREHOLDERS' EQUITY:  -- (Continued)

     On September 30, 1996, the Company acquired the net assets of Impax
Pharmaceuticals, LLC in exchange for the issuance of 2,136,362 shares of Common
Stock, 726,637 shares of Series A Preferred Stock and 410,000 shares of Series
B Preferred Stock.


     The holders of Preferred Stock have various rights and preferences as
follows:

Voting


     Each share of Series A, B, C and D has voting rights equal to an
equivalent number of shares of Common Stock into which it is convertible and
votes together as one class with the Common Stock.


     As long as at least 400,000 shares of Redeemable Convertible Preferred
Stock remain outstanding, the Company must obtain approval from a majority of
the holders of Redeemable Convertible Preferred Stock in order to alter the
Articles of Incorporation as related to Redeemable Convertible Preferred Stock,
change the authorized number of shares of Redeemable Convertible Preferred
Stock, repurchase any shares of Common Stock other than shares subject to the
right of repurchase by the Company, change the authorized number of Directors,
authorize a dividend for any class or series other than Redeemable Convertible
Preferred Stock, create a new class of stock or effect a merger, consolidation
or sale of assets where the existing shareholders retain less than 50% of the
voting stock of the surviving entity.


Dividends


     Holders of Series A, B, C and D Redeemable Convertible Preferred Stock are
entitled to receive noncumulative dividends at the per annum rate of $0.01,
$0.05, $0.0877 and $0.50 per share, respectively, when and if declared by the
Board of Directors. No dividends on Convertible Redeemable Preferred Stock or
Common Stock have been declared by the Board from inception through December
31, 1998.


Liquidation


     In the event of any liquidation, dissolution or winding up of the Company,
including a merger, acquisition or sale of assets where the beneficial owners
of the Company's Common Stock and Convertible Redeemable Preferred Stock own
less than 51% of the resulting voting power of the surviving entity, the
holders of Series A, B C and D Redeemable Convertible Preferred Stock are
entitled to receive an amount of $1.00, $5.00, $8.76 and $5.00 per share,
respectively, plus any declared but unpaid dividends prior to and in preference
to any distribution to the holders of Common Stock. The remaining assets, if
any, shall be distributed and shared pro rata among all holders of capital
stock of the Company on a basis which assumes conversion of all outstanding
Preferred Stock into Common Stock. Should the Company's legally available
assets be insufficient to satisfy the liquidation preferences, the funds will
be distributed ratably in proportion to the respective amounts which would be
payable on the shares held by them if the respective preference amounts were
paid in full.


Conversion


     Each share of Series A, B, C and D Redeemable Convertible Preferred Stock
is convertible, at the option of the holder, according to a conversion ratio,
subject to adjustment for dilution. Each share of Series A, B and D Redeemable
Convertible Preferred Stock automatically converts on a 1 to 1 basis into the
number of shares of Common, Series C converts on a 1 to 1.7534 basis. Automatic
conversion should occur upon the closing of a public offering of Common Stock
at a per share price of at least $5.00 per share with gross proceeds of at
least $5,000,000.

NOTE 9 -- SHAREHOLDERS' EQUITY:  -- (Continued)

Redemption

     On or at any time after September 30, 2005, for Series A, B, C and D, the
Company may, at any time, at the option of the Board of Directors, redeem in
whole or in part any shares of Series A, B, C and D by paying in cash, $1.00,
$5.00, $8.767 and $5.00 per share, respectively, plus all declared but unpaid
dividends if any.


Warrants for Redeemable Convertible Preferred Stock

     In connection with issuing revolving credit notes in July 1995 (see Note
7) to the Company's founders, the Company issued warrants to purchase 715,000
shares of Series A Redeemable Convertible Preferred Stock for $1.00 per share.
There were no warrants outstanding at December 31, 1998. Using the
Black-Scholes pricing model, the Company determined that the fair value of the
warrants was $369,000 at the date of grant. A total of $89,000 was amortized
and the remaining amount of $280,000 was treated as issuance costs based on the
conversions of the debt to Series A reedemable convertible preferred stock.


Common Stock

     The Company's Articles of Incorporation, as amended, authorize the Company
to issue 15,000,000 shares of no par value Common Stock.


Warrants for Common Stock

     In connection with a deferred compensation agreement in 1998 with the
Company's founders, the Company issued warrants to purchase 520,000 shares of
Common Stock for $2.50 per share. Such warrants are outstanding at December 31,
1998 and expire in 2003. The Company determined that the intrinsic value of the
warrants at the date of grant was $260,000 and has charged this amount to
expense in 1998 in accordance with APB No. 25.

NOTE 10 -- STOCK OPTION PLANS:

     In September 1996, the Company adopted the 1996 Stock Option Plan (the
"Plan"). The Plan provides for the granting of stock options to employees and
consultants of the Company. Options granted under the Plan may be either
incentive stock options or nonqualified stock options. Incentive stock options
("ISO") may be granted only to Company employees (including officers and
directors who are also employees). Nonqualified stock options ("NSO") may be
granted to Company employees and consultants. The Company has reserved 500,000
shares of Common Stock for issuance under the Plan. To date, options granted
generally vest from three to five years.

     On September 30, 1996, as part of its acquisition of the assets of Impax
Pharmaceuticals, LLC, the Company agreed to exchange option agreements entitled
holders to acquire Common or Preferred Units of the LLC for options entitled
these same holders to acquire equivalent amounts of common and Preferred Stock
in the Company. Accordingly, on September 30, 1996, the Company reflected
options granted to prior members of the LLC covering 113,000 shares.

     Effective June 1, 1998, the Company's Board of Directors approved the
re-pricing of all outstanding options to $2.50 per share, the fair market value
of common stock on that date. As a result, all outstanding options at June 1,
1998 were effectively rescinded and re-issued at an exercise price of $2.50 per
share.

Fair value disclosures

     Had compensation cost for the Company's stock-based compensation plan been
determined based on the fair value at the grant dates for the awards under a
method prescribed by SFAS No. 123, the Company's net loss would have been
increased to the pro forma amounts indicated below (in thousands):




                           Year Ended December 31,

     The pro forma results may not representative of the effect on reported
operations for future years.

     Of the $446,000 pro forma increase in net loss for 1998, $388,000 is
attributable to a re-pricing of outstanding stock options and $58,000 is due to
normal amortization.

$90,000 of the unearned compensation was amortized to expense during the period
ended June 30, 1999. The Company amortizes unearned compensation over the

       hereinafter defined) or Seller Common Stock or Seller Preferred Stock),
       reorganization, recapitalization or other like change with respect to
       Buyer Common Stock, Seller Common Stock, Seller Preferred Stock or Buyer
       Preferred Stock occurring after the date hereof and prior to the
       Effective Time.

     Buyer Common Stock and Buyer Series 1 Preferred Stock shall collectively
be referred to herein as "Buyer Stock."

     SECTION 2.02 Conversion of Buyer Capital Stock. As of the Effective Time,
by virtue of the Merger and without any action on the part of any holder of any
shares of the Series C Convertible Preferred Stock, $.01 par value per share,
of Buyer (the "Buyer Series C Preferred") or the Series D Convertible Preferred
Stock, $.01 par value per share, of Buyer (the "Buyer Series D Preferred" and,
together with the Buyer Series C Preferred, the "Buyer Preferred Stock"):

   (a) Cancellation of Treasury Stock. All shares of Buyer Stock that are
       owned directly or indirectly by Buyer as treasury stock shall be
       cancelled and retired and shall cease to exist and no stock of Buyer or
       other consideration shall be delivered in exchange therefor.

   (b) Exchange Multiplier for Buyer Series C Preferred. Subject to Section
       2.04, each issued and outstanding share of Buyer Series C Preferred
       (other than shares to be cancelled in accordance with Section 2.02(a)
       and any shares of Buyer Series C Preferred which are held by
       shareholders who are dissenting shareholders pursuant to Section 262 of
       the Delaware GCL) shall be converted into the right to receive fifty
       (50) (the "Buyer Series C Exchange Multiplier") fully paid and
       non-assessable shares of Buyer Common Stock (subject to anti-dilution
       protection as set forth in the Certificate of Designations, Rights and
       Preferences of the Buyer Series C Preferred).

       All such shares of Buyer Series C Preferred when so converted shall no
       longer be outstanding and shall automatically be cancelled and retired
       and shall cease to exist, and each holder of a certificate representing
       any such shares shall cease to have any rights with respect thereto,
       except the right to receive the shares of Buyer Common Stock and any cash

       and any shares of Buyer Preferred Stock which are held by shareholders
       who are dissenting shareholders pursuant to Section 262 of the Delaware
       GCL) shall be converted into the right to receive one (the "Buyer Series
       D Exchange Multiplier") fully paid and non-assessable shares of Buyer
       Series 1 Preferred Stock.

       All such shares of Buyer Series D Preferred when so converted shall no
       longer be outstanding and shall automatically be cancelled and retired
       and shall cease to exist, and each holder of a certificate representing
       any such shares shall cease to have any rights with respect thereto,
       except the right to receive the shares of Buyer Series 1 Preferred Stock
       and any cash in lieu of fractional shares of Buyer Series 1 Preferred
       Stock to be issued or paid in consideration therefor upon the surrender
       of such certificate in accordance with Section 2.04, without interest.

   (d) Adjustments to Conversion. The Buyer Series C Exchange Multiplier and
       Buyer Series D Exchange Multiplier shall be adjusted to reflect fully
       the effect of any stock split, reverse split, stock dividend (including
       any dividend or distribution of securities convertible into Buyer Common
       Stock, Buyer Preferred Stock, Seller Common Stock or Seller Preferred
       Stock), reorganization, recapitalization or other like change with
       respect to Buyer Common Stock, Seller Common Stock, Seller Preferred

     SECTION 2.03 Dissenting Shares. Notwithstanding anything to the contrary
contained in this Agreement, in the event appraisal rights are available to the
holders of Buyer Stock, Buyer Preferred Stock or Seller Stock pursuant to
applicable law, any shares of Buyer Stock, Buyer Preferred Stock or Seller
Stock held by a person who objects to the Merger and who complies with all of
the provisions of applicable law concerning the rights of such person to
dissent from the Merger and to require appraisal of such person's shares of
Buyer Stock, Buyer Preferred Stock or Seller Stock, as the case may be (the
"Dissenting Shares"), shall not be converted into the right to receive shares
of Buyer Stock pursuant to Sections 2.01 and 2.02 of this Agreement but shall
become the right to receive such consideration as may be determined to be due
to the holder of such Dissenting Shares pursuant to applicable law; provided,
however, that the Dissenting Shares held by a person at the Effective Time who
shall, after the Effective Time, withdraw the demand for appraisal or lose the
right to appraisal, in either case pursuant to applicable law, shall be deemed
to have converted, as of the Effective Time, his or her shares of Buyer Stock,
Buyer Preferred Stock or Seller Stock, as the case may be, into shares of Buyer
Stock pursuant to Sections 2.01 and 2.02 of this Agreement.


     SECTION 2.04 Exchange of Certificates. The procedures for exchanging
outstanding shares of Seller Common Stock, Seller Preferred Stock and Buyer
Preferred Stock for Buyer Common Stock and Buyer Series 1 Preferred Stock
pursuant to the Merger are as follows:


   (a) Exchange Agent. As of the Effective Time, Buyer shall deposit with a bank
       or trust company designated by Buyer and Seller (the "Exchange Agent"),
       for the benefit of the holders of shares of Seller Stock and Buyer
       Preferred Stock for exchange in accordance with this Section 2.04,
       through the Exchange Agent, (i) certificates representing the shares of
       Buyer Stock (such shares of Buyer Stock, together with cash in lieu of
       fractional shares and any dividends or distributions with respect
       thereto, being hereinafter referred to as the "Exchange Fund") issuable
       pursuant to Sections 2.01 and 2.02, less shares of Buyer Stock deposited
       in the Escrow, as set forth below, in exchange for outstanding shares of
       Seller Stock and Buyer Preferred Stock and (ii) cash, as required, in an
       amount sufficient to make payments of cash in lieu of fractional shares,
       if any, required pursuant to Section 2.04(e).


   (b) Subject to the provisions of Section 2.03, as of the Effective Time, all
       holders of Seller Stock (the "Seller Stockholders," who are listed on
       Exhibit C attached hereto, which shall be updated at the Closing) shall
       be required to deposit an aggregate of 1,690,274 shares of Buyer Common
       Stock and 17,000 shares of Buyer Series 1 Preferred Stock to be received
       by them in the Merger into an escrow account (the "Escrow"), which shares
       shall be held and distributed in accordance with the terms of an Escrow
       Agreement (the "Escrow Agreement") to be entered into by and among Buyer,
       the Seller Stockholders, the Seller Stockholder Agent (as defined herein)
       and the Exchange Agent or such other party as the parties may mutually
       agree upon, as escrow agent (the "Escrow Agent"), in substantially the
       form attached hereto as Exhibit D.


   (c) As of the Effective Time, Buyer shall deposit or cause to be deposited
       with the Escrow Agent certificates (issued in the name of the Escrow
       Agent or its nominee) representing the Buyer Common Stock deposited in
       the Escrow and Buyer Series 1 Preferred Stock deposited in the Escrow
       (together, the "Escrow Shares"), for the purpose of securing the
       indemnification obligations of the Seller Stockholders set forth in this
       Agreement. The Escrow Shares shall be held by the Escrow Agent under the
       Escrow Agreement pursuant to the terms thereof and shall be disbursed in
       accordance with the terms of the Escrow Agreement. The adoption of this
       Agreement and the approval of the Merger by the Seller Stockholders shall
       constitute approval of the Escrow Agreement and of all of the
       arrangements relating thereto, including without limitation the placement
       of the Escrow Shares in escrow and the appointment of the Seller
       Stockholder Agent (as defined herein). Any shares of Buyer Stock or other
       equity securities issued or distributed by Buyer (including shares issued
       upon a stock split) ("New Shares") in respect of Buyer Stock in the
       Escrow which have not been released from the Escrow shall be added to the
       Escrow and become a part thereof. New Shares issued in respect of Buyer
       Stock which have been released from the Escrow shall not be added to the
       Escrow, but shall be distributed to the holders thereof. When and if cash
       dividends on Buyer Stock in the Escrow shall be declared and paid, they
       shall not be added to the Escrow, but shall be paid to those on whose
       behalf such Buyer Stock is held who, at the Effective Time, held Seller
       Stock. Each Seller Stockholder shall have voting rights with respect


                                      A-4
<PAGE>

       to the shares of Buyer Stock contributed to the Escrow on behalf of such
       Seller Stockholder (and on any voting securities added to the Escrow in
       respect of such shares of Buyer Stock) so long as such shares of Buyer
       Stock or other voting securities are held in the Escrow. As the record
       holder of such shares, the Escrow Agent shall vote such shares in
       accordance with the instructions of the Seller Stockholders having the
       beneficial interest therein and shall promptly deliver copies of all
       proxy solicitation materials to such Seller Stockholders. Buyer shall
       show the Buyer Stock contributed to the Escrow Fund as issued and
       outstanding on its balance sheet.


   (d) Exchange Procedures. Promptly after the Effective Time, Buyer shall
       instruct the Exchange Agent and the Exchange Agent shall mail to each
       holder of record of a certificate or certificates which immediately prior
       to the Effective Time represented outstanding shares of Seller Stock and
       Buyer Preferred Stock (the "Certificates") whose shares of Seller Stock
       and Buyer Preferred Stock were converted pursuant to Sections 2.01 and
       2.02 into the right to receive shares of Buyer Stock (i) a letter of
       transmittal (which shall specify that delivery shall be effected, and
       risk of loss and title to the Certificates shall pass, only upon delivery
       of the Certificates to the Exchange Agent, and shall be in such form and
       have such other provisions as Buyer and Seller may reasonably specify)
       and (ii) instructions for effecting the surrender of the Certificates in
       exchange for certificates representing shares of Buyer Stock (plus cash
       in lieu of fractional shares, if any, of Buyer Stock as provided below).
       Upon surrender of a Certificate for cancellation to the Exchange Agent or
       to such other agent or agents as may be mutually appointed by Buyer and
       Seller, together with such letter of transmittal, duly executed, the
       holder of such Certificate shall be entitled to receive in exchange
       therefor a certificate representing that number of whole shares of Buyer
       Stock which such holder has the right to receive pursuant to the
       provisions of this Article II after taking into account all the shares of
       Seller Stock or Buyer Preferred Stock then held by such holder under all
       such Certificates so surrendered, and the Certificate so surrendered
       shall immediately be cancelled. In the event of a transfer of ownership
       of Seller Stock or Buyer Preferred Stock which is not registered in the
       transfer records of Seller, or Buyer, as the case may be, a certificate
       representing the proper number of shares of Buyer Stock may be issued to
       a transferee if the Certificate representing such Seller Stock or Buyer
       Preferred Stock is presented to the Exchange Agent, accompanied by all
       documents required to evidence and effect such transfer and by evidence
       that any applicable stock transfer taxes have been paid. Until
       surrendered as contemplated by this Section 2.04, each Certificate shall
       be deemed at any time after the Effective Time to represent only the
       right to receive upon such surrender the certificate representing shares
       of Buyer Stock and cash in lieu of any fractional shares of Buyer Stock
       as contemplated by this Section 2.04.


   (e) Distributions with Respect to Unexchanged Shares. No dividends or other
       distributions declared or made after the Effective Time with respect to
       Buyer Stock with a record date after the Effective Time shall be paid to
       the holder of any unsurrendered Certificate with respect to the shares of
       Buyer Stock to which such holder is entitled until the holder of record
       of such Certificate shall surrender such Certificate. Subject to the
       effect of applicable laws, following surrender of any such Certificate,
       there shall be paid to the record holder of the certificates representing
       whole shares of Buyer Stock issued in exchange therefor, without
       interest, (i) at the time of such surrender, the amount of any cash
       payable in lieu of a fractional share of Buyer Stock to which such holder
       is entitled pursuant to subsection (g) below and the amount of dividends
       or other distributions with a record date after the Effective Time which
       would otherwise have been previously paid with respect to such whole
       shares of Buyer Stock and (ii) at the appropriate payment date, the
       amount of dividends or other distributions with a record date after the
       Effective Time but prior to surrender and a payment date subsequent to
       surrender payable with respect to such whole shares of Buyer Stock.


   (f) No Further Ownership Rights in Seller Stock. All shares of Buyer Stock
       issued upon the surrender for exchange of Certificates in accordance with
       the terms hereof (including any cash paid pursuant to subsection (c) or
       (g) of this Section 2.04) shall be deemed to have been issued in full
       satisfaction of all rights pertaining to such shares of Seller Stock or
       Buyer Preferred Stock, as the case may be, and from and after the
       Effective Time there shall be no further registration of transfers on the
       stock transfer books of the Surviving Corporation of the shares of Seller
       Stock or Buyer Preferred Stock which were outstanding immediately prior
       to the Effective Time. If, after the Effective Time, Certificates are
       presented


                                      A-5
<PAGE>

       to the Surviving Corporation for any reason, they shall be cancelled and
       exchanged as provided in this Section 2.04.


   (g) No Fractional Shares. No certificate or scrip representing fractional
       shares of Buyer Stock shall be issued upon the surrender for exchange of
       Certificates, and such fractional share interests will not entitle the
       owner thereof to vote or to any other rights of a stockholder of Buyer.
       Notwithstanding any other provision of this Agreement, each holder of
       shares of Seller Stock or Buyer Preferred Stock exchanged pursuant to the
       Merger who would otherwise have been entitled to receive a fraction of a
       share of Buyer Stock (after taking into account all Certificates
       delivered by such holder) shall receive, in lieu thereof, cash (without
       interest) in an amount equal to such fractional part of a share of Buyer
       Stock multiplied by the Average Stock Price.

       "Average Stock Price" means the average of the daily closing prices of
       Buyer Common Stock on the Nasdaq SmallCap Market for the twenty
       consecutive trading days ending on the second trading day immediately
       prior to the Closing Date. With regard to the Buyer Preferred Stock, the
       "Average Stock Price" shall be determined by multiplying the number of
       shares of Buyer Common Stock issuable upon conversion of each share of
       Buyer Preferred Stock by the Average Stock Price for the Buyer Common
       Stock.


   (h) Termination of Exchange Fund. Any portion of the Exchange Fund which
       remains undistributed to the stockholders of Seller or Buyer, as the case
       may be, for 180 days after the Effective Time shall be delivered to
       Buyer, upon demand, and any stockholders of Seller or Buyer, as the case
       may be, who have not previously complied with this Section 2.04 shall
       thereafter look only to Buyer for payment of their claim for such Buyer
       Stock, any cash in lieu of fractional shares of Buyer Stock and any
       dividends or distributions with respect to Buyer Stock.


   (i) No Liability. To the extent permitted by applicable law, neither Buyer
       nor Seller shall be liable to any holder of shares of Seller Stock, Buyer
       Preferred Stock or Buyer Stock, as the case may be, for such shares (or
       dividends or distributions with respect thereto) delivered to a public
       official pursuant to any applicable abandoned property, escheat or
       similar law.


   (j) Withholding Rights. Each of Buyer and the Surviving Corporation shall be
       entitled to deduct and withhold from the consideration otherwise payable
       pursuant to this Agreement to any holder of shares of Seller Stock or
       Buyer Preferred Stock such amounts as it is required to deduct and
       withhold with respect to the making of such payment under the Code, or
       any provision of state, local or foreign tax law. To the extent that
       amounts are so withheld by Surviving Corporation or Buyer, as the case
       may be, such withheld amounts shall be treated for all purposes of this
       Agreement as having been paid to the holder of the shares of Seller Stock
       or Buyer Preferred Stock in respect of which such deduction and
       withholding was made by Surviving Corporation or Buyer, as the case may
       be.


   (k) Lost Certificates. If any Certificate shall have been lost, stolen or
       destroyed, upon the making of an affidavit of that fact by the person
       claiming such Certificate to be lost, stolen or destroyed and the posting
       by such person of a bond in such reasonable amount as the Surviving
       Corporation may direct as indemnity against any claim that may be made
       against it with respect to such Certificate (unless such requirement to
       post a bond shall be waived by the Surviving Corporation), the Exchange
       Agent will issue in exchange for such lost, stolen or destroyed
       Certificate the shares of Buyer Stock and any cash in lieu of fractional
       shares, and unpaid dividends and distributions on shares of Buyer Stock
       deliverable in respect thereof pursuant to this Agreement.

     SECTION 2.05 Conversion of Options. At the Effective Time, each option
granted by Seller to purchase shares of Seller Common Stock ("Seller Stock
Option") which is outstanding and unexercised immediately prior thereto shall
cease to represent a right to acquire shares of Seller Common Stock and shall
be converted automatically into an option to purchase the number of whole
shares of Buyer Common Stock (rounded down, if applicable) equal to the number
of whole shares of Seller Common Stock subject to such option multiplied by the
Seller Common Exchange Multiplier, at a price per share of Buyer Common Stock
equal to (i) the exercise


                                      A-6
<PAGE>

price for the shares of Seller Common Stock purchasable pursuant to such Seller
Stock Option immediately prior to the Effective Time divided by (ii) the Seller
Common Exchange Multiplier, and shall otherwise be subject to the terms of the
Seller Employee Plans (as defined in Section 3.11) pursuant to which such
options were issued and the agreements evidencing grants thereunder or, at the
option of the Surviving Corporation, may as otherwise be contained in any Buyer
Option Plan. Subject to the foregoing, the adjustment provided herein with
respect to any options which are "incentive stock options" (as defined in
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") shall
be and is intended to be effected in a manner which is consistent with Section
424(a) of the Code. Subject to the adjustments noted herein, the duration and
other terms of the option shall be the same as the original option except that
all references to (i) Seller Common Stock shall be deemed to be references to
Buyer Common Stock and (ii) the Company shall be deemed to be references to
Buyer. Further, any and all vesting or performance requirements or conditions
affecting any outstanding restricted stock, performance stock, stock option,
stock appreciation right, phantom stock, bonus, award, right, grant or any
other arrangement with any director or employee of Seller shall be based on the
terms of the respective Seller Employee Plan and the agreements evidencing
grants thereunder or, at the option of the Surviving Corporation, may as
otherwise be contained in any Buyer Option Plan. This Section 2.05 is intended
to be for the benefit of holders of options to purchase the Common Stock of
Seller.


     SECTION 2.06 Conversion of Warrants. At the Effective Time, each warrant
granted by Seller to purchase shares of Seller Common Stock ("Seller Warrant)"
which is outstanding and unexercised immediately prior thereto shall cease to
represent a right to acquire shares of Seller Common Stock and shall be
converted automatically into a warrant to purchase the number of whole shares
of Buyer Common Stock (rounded down as applicable) equal to the number of whole
shares of Seller Common Stock subject to such warrant multiplied by the Seller
Common Exchange Multiplier, at a price per share of Buyer Common Stock equal to
(i) the exercise price for the shares of Seller Common Stock purchasable
pursuant to such Seller Warrant immediately prior to the Effective Time divided
by (ii) the Seller Common Exchange Multiplier, and shall otherwise be subject
to the terms of the agreements evidencing grants of such Seller Warrants and
shall thereupon be assumed by Buyer. Subject to the adjustments noted herein,
the duration and other terms of the warrant shall be the same as the original
warrant except that all references to (i) Seller Common Stock shall be deemed
to be references to Buyer Common Stock and (ii) the Company or Seller shall be
deemed to be references to the Surviving Corporation.


                                  ARTICLE III

                   REPRESENTATIONS AND WARRANTIES OF SELLER


     Seller represents and warrants to Buyer that the statements contained in
this Article III are true and correct, except as set forth herein and in the
disclosure schedules delivered by Seller to Buyer on or before the date of this
Agreement (the "Seller Disclosure Schedules"). The Seller Disclosure Schedules
shall be arranged in individual schedules corresponding to the numbered
paragraphs set forth below and the disclosure in any schedules shall qualify
other schedules in this Article III only to the extent that it is reasonably
apparent from a reading of such disclosure that it also qualifies or applies to
such other schedules. Without limiting the foregoing, the mere listing (or
inclusion of a copy) of a document or other item shall not be deemed adequate
to disclose an exception to a representation or warranty made herein (unless
the representation or warranty concerns the existence of the document or the
other item itself).


     SECTION 3.01 Organization of Seller. Seller, which is a corporation is
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation, has all requisite corporate power to own,
lease and operate its property and to carry on its business as now being
conducted, and is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which the failure to be so
qualified would have a material adverse effect on the business, properties,
financial condition or results of operations of Seller taken as a whole (a
"Seller Material Adverse Effect"); provided, however, that for purposes of this
Agreement, the following events, shall not be taken into account in determining
whether there has been or would be a "Seller Material Adverse Effect" on or
with respect to Seller taken as a whole: (A) changes, events or occurrences in
the United States securities markets which are not specific to Seller, (B)
changes, events or occurrences in the world economy which are not specific to
the Seller, (C) the existence of this Agreement or the transactions
contemplated hereby or the announcement thereof, (D) any changes in generally
accepted


                                      A-7
<PAGE>

accounting principles ("GAAP") and (E) changes, events or occurrences relating
to the pharmaceutical industry in general, and not specifically to Seller.
Except as set forth on Schedule 3.01, Seller does not directly or indirectly
own any equity or similar interest in, or any interest convertible into or
exchangeable or exercisable for, any corporation, partnership, joint venture or
other business association or entity, excluding securities in any publicly
traded company held for investment by Seller and comprising less than five
percent (5%) of the outstanding stock of such company. Except as set forth on
Schedule 3.01, the Seller does not own or control (directly or indirectly), or
own or hold any right to acquire, any stock, partnership interest, joint
venture interest, equity participation or other security or interest in any
other entity, corporation, partnership, trust or any other business
association.

     SECTION 3.02 Seller Capital Structure; Irrevocable Proxy and Voting
Agreement. (a) The authorized capital stock of Seller consists of (i)
15,000,000 shares of Seller Common Stock, and (ii) 15,000,000 shares of Seller
Preferred Stock. The Seller Preferred Stock has been designated into the
following series: 1,600,000 shares of Seller Series A, 500,000 shares of Seller
Series B, 600,000 shares of Seller Series C and 3,400,000 shares of Seller
Series D. As of June 30, 1999, (i) 2,147,362 shares of Seller Common Stock,
1,580,000 shares of Seller Series A, 428,600 shares of Seller Series B, 519,631
shares of Seller Series C, and 3,400,000 shares of Seller Series D were issued
and outstanding, all of which are validly issued, fully paid and nonassessable,
and (ii) no shares of Seller Common Stock or Seller Preferred Stock were held
in the treasury of Seller. Schedule 3.02 shows (i) the ownership of the Seller
Stock and (ii) the number of shares of Seller Common Stock reserved for future
issuance pursuant to stock options and warrants granted and outstanding as of
the date hereof, and the plans under which such options were granted, if
applicable (collectively, the "Seller Stock Plans"). All shares of Seller Stock
subject to issuance as specified above are duly authorized and, upon issuance
on the terms and conditions specified in the instruments pursuant to which they
are issuable, shall be validly issued, fully paid and nonassessable. There are
no bonds, debentures, notes or other indebtedness of Seller having the right to
vote (or convertible into securities having the right to vote) on any matters
on which shareholders of Seller may vote. There are no obligations, contingent
or otherwise, of Seller to repurchase, redeem or otherwise acquire any shares
of Seller Common Stock, Seller Preferred Stock, or to provide funds to or make
any material investment (in the form of a loan, capital contribution or
otherwise) in any other entity.

     (b) Except as set forth on Schedule 3.02 or as reserved for future grants
of options under Seller Stock Plans, there are no equity securities of any
class of Seller, or any security exchangeable or convertible into or
exercisable for such equity securities, issued, reserved for issuance or
outstanding. Except as set forth on Schedule 3.02, there are no options,
warrants, equity securities, calls, rights, commitments or agreements of any
character to which Seller is a party or by which Seller is bound (including
under letters of intent, whether binding or nonbinding) obligating Seller to
issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of capital stock or other equity interests of Seller or obligating
Seller to grant, extend, accelerate the vesting of, otherwise modify or amend
or enter into any such option, warrant, equity security, call, right,
commitment or agreement except under Seller Stock Plans. Schedule 3.02 sets
forth a complete list of all outstanding warrants of the Seller and Seller has
provided to Buyer true and correct copies of each of such warrants. To the
knowledge of Seller, there are no voting trusts, proxies or other voting
agreements or understandings with respect to the shares of capital stock or
other equity interests of Seller.

     (c) No consent of the holders of any stock options granted pursuant to
Seller Stock Plans ("Seller Stock Options") is required in connection with the
conversion of the Seller Stock Options into options to acquire Buyer Common
Stock in accordance with Section 2.05.

are in fair or good operating condition and repair, reasonable wear and tear
excepted, are usable in the ordinary course of business and are adequate and
suitable for the uses to which they are being put, except where the failure to

Adverse Effect. None of such items requires any repairs or replacement except
for maintenance in the ordinary course of business or such other repairs or
replacements which are not material, individually or in the aggregate, in
nature or cost. All such assets and property are located at the 30831 Huntwood
Avenue premises in Hayward, California or as otherwise identified on Schedule
3.08 hereto.

     (c) The Seller is not contemplating any capital expenditure in excess of

or commitment, written or oral, including without limitation any obligations
for money borrowed or under leases, other than those identified on Schedule
3.09 hereto (the "Seller Material Contracts"); true, correct and complete
copies of all Seller Material Contracts previously have been furnished to
Buyer. Except as set forth on Schedule 3.09, the Seller is not in default, and
no event has occurred which with the giving of notice or the passage of time or
both would constitute a default by the Seller or, to the best of Seller's
knowledge, any other party under any Seller Material Contract or any other
material obligation owed by the Seller and, to the best of Seller's knowledge,
no event has occurred which with the giving of notice or the passage of time or
both would constitute a default by any other party to any such Seller Material
Contract or obligation. Except as set forth on Schedule 3.09, the continuation,
validity and effectiveness of all Seller Material Contracts will in no way be
affected by the transactions contemplated hereby; and there are no negotiations
pending to revise the terms of any such Seller Material Contracts. Except as
set forth on Schedule 3.09, the Seller is not party to or bound by any
contract, agreement, relationship or commitment, whether or not deemed

Seller to acquire any property or assets or conduct their respective business
or provide services to any person or entity anywhere in the world.

     SECTION 3.10 Litigation. Except as set forth on Schedule 3.10, there is no
claim, counter-claim, action, suit, order, proceeding or investigation pending
or to the knowledge of the Seller, threatened against or involving the Seller,
or pending or, to the knowledge of the Seller, threatened against any of the
respective officers,


                                      A-12
<PAGE>

behalf of the Seller with respect to or affecting the Seller, its accounts,
business, properties, assets or rights, or relating to the transactions
contemplated hereby, before any court, agency, regulatory, administrative or
other governmental body or officer or before any arbitrator, nor, to the
knowledge of the Seller, is there any reasonable basis for any such claim,
action, suit, proceeding or governmental, administrative or regulatory
investigation. The Seller is not directly subject to or affected by any order,
judgment, decree or ruling of any court or governmental agency. The Seller has
not received any written opinion or memorandum of legal advice from legal
counsel to the effect that any of them are exposed to any liability which may
be material to the business, prospects, results of operations, financial
condition or assets of the Seller. Except as set forth on Schedule 3.10, the
Seller is not engaged in any legal action to recover monies due it or for
damages sustained by it, and none of the assets of the Seller nor any of its
business practices are in any manner, directly or indirectly, affected by
injunction of any court or governmental, administrative or regulatory agency,
body or officer.


     SECTION 3.11 Employee Benefit Plans. (a) Schedule 3.11 sets forth all
employee benefit plans (as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) and all bonus, stock option,
stock purchase, equity, incentive, deferred compensation, supplemental

care, flexible spending or severance plans, programs or agreements, for the
benefit of, or relating to, any current or former employee, director or
independent contractor of Seller or any entity which is, or has been, a member
(an "ERISA Affiliate") of (i) a controlled group of corporations, (ii) a group
of trades or businesses (whether or not incorporated) under common control with
Seller, or (iii) an affiliated service group, all within the meaning of Section
414 of the Code or Section 4001(a)(14) of ERISA, of which includes the Seller
(together, the "Seller Employee Plans").


     (b) With respect to each Seller Employee Plan, Seller has delivered to
Buyer, a true and correct copy of (i) the most recent annual report (Form 5500)
filed with the IRS (and the related financial statement), (ii) such Seller
Employee Plan and any amendments or summary plan descriptions with respect
thereto, (iii) each trust agreement and group annuity contract, if any,
relating to such Seller Employee Plan, (iv) the most recent actuarial report or
valuation relating to a Seller Employee Plan subject to Title IV of ERISA, and
(v) the most recent determination letter issued by the Internal Revenue
Service, as well as any other determination letter, private letter ruling,
opinion letter or prohibited transaction exemption issued by the Internal
Revenue Service or the Department of Labor within the last six years and any
application therefor which is currently pending.


     (c) Except as set forth on Schedule 3.11, neither the Seller, nor any of
its ERISA Affiliates (i) has ever maintained or been obligated to contribute to
a single employer, multiple employer or multi-employer pension plan (within the
meaning of Section 3(2) of ERISA) which is or was covered by Title IV of ERISA
or by Section 302 of ERISA or 412 of the Code, and (ii) has incurred or may
incur any direct or indirect liability under Title IV of ERISA or Section 302
of ERISA or Section 412 of the Code. With respect to the Seller Employee Plans,
individually and in the aggregate, no event has occurred, and there exists no
condition or set of circumstances in connection with which Seller could be
subject to any liability that is reasonably likely to have a Seller Material
Adverse Effect under ERISA, the Code or any other applicable law.


     (d) With respect to the Seller Employee Plans, individually and in the
aggregate, there are no funded benefit obligations for which contributions have
not been made or properly accrued and there are no unfunded benefit obligations
which have not been accounted for by reserves, or otherwise properly footnoted,
in either case, in accordance with GAAP, on the financial statements of Seller.



     (e) The Seller and its ERISA Affiliates have complied in all respects with
the provisions of Section 4980B of the Code with respect to each Seller
Employee Plan which is a group health plan within the meaning of Section
5001(b)(1) of the Code. Seller does not maintain or contribute to, nor is it
obligated under any plan, contract, policy or arrangement providing health or
death benefits (whether or not insured) to current or former employees or other
personnel beyond the termination of their employment or other services.


     (f) Except as set forth on Schedule 3.11 and except as provided for in
this Agreement, Seller is not a party to any oral or written (i) agreement with
any current or former officer or other key employee of Seller, the benefits of
which are contingent, or the terms of which are materially altered, upon the
occurrence of a transaction involving Seller of the nature contemplated by this
Agreement, (ii) agreement with any current or former officer


                                      A-13
<PAGE>

of Seller providing any term of employment or compensation guarantee extending
for a period longer than eighteen months from the date hereof and for the
payment of compensation in excess of $100,000 per annum, or (iii) agreement or
plan, including any stock option plan, stock appreciation right plan,
restricted stock plan or stock purchase plan, any of the benefits of which will
be increased, or the vesting or funding of the benefits of which will be
accelerated, by the occurrence of any of the transactions contemplated by this
Agreement or the value of any of the benefits of which will be calculated on
the basis of any of the transactions contemplated by this Agreement.

     (g) There are no pending or, to Seller's knowledge, threatened claims,
actions, suits, termination proceedings, or investigations by any Governmental
Entity against or involving any Seller Benefit Plan. Any Seller Benefit Plan
intended to be qualified under Section 401(a) of the Code has received a
determination letter from the Internal Revenue Service to that effect (which
has not been revoked) and nothing has occurred since the date of the most
recent determination letter that would adversely affect such qualification.

     SECTION 3.12 Salaries. Schedule 3.12 contains a true, complete and correct
list setting forth (i) the names, job descriptions/titles, current compensation

Except as set forth on Schedule 3.12, there has been no increase in the
compensation of any of the foregoing individuals or independent contractors
since June 30, 1999. There has not been any promise by the Seller to the
employees listed on Schedule 3.12 orally or in writing of any bonus or increase
in compensation, whether or not legally binding, except for increases in the
ordinary course of business consistent with past compensation practices of the
Seller. Except as set forth on Schedule 3.12, the Seller has not made any
prepayments of salaries, bonuses or any other amounts due to any of its
employees or former employees. All obligations to employees, whether for
salaries, commissions, bonuses, vacation or otherwise, which are required to be
accrued on the Financial Statements in accordance with generally accepted
accounting principles consistently applied have been accrued on the Financial
Statements in accordance with generally accepted accounting principles
consistently applied.

     SECTION 3.13 Personnel Agreements, Plans and Arrangements. Except as
listed in Schedule 3.13, the Seller is not a party to or obligated with respect
to any (a) outstanding contracts with current or former employees, agents,
consultants, advisers, salespeople, sales representatives, distributors, sales
agents, independent contractors, or dealers, or (b) collective bargaining
agreements or contracts with any labor or trade union, employee bargaining
agency or other representative of employees or any employee benefits provided
for by any such agreement, true, correct and complete copies of which
previously have been furnished to Buyer. No strike, picketing, slow-down, work
stoppage, lock-out, union organizational activity or other similar occurrence
has occurred or is pending or, to the knowledge of the Seller, is threatened
against the Seller. Except as disclosed on Schedule 3.13, the Seller has
complied in all material respects with all applicable laws relating to the
employment of labor, including but not limited to provisions thereof relating
to wages, hours, vacation pay, equal opportunity, collective bargaining and the
payment, deduction and remittance of all amounts required to be deducted and/or
remitted in respect of wages and salaries and of other Taxes and such
deductions are consistent with past practices and in accordance with generally
accepted accounting principles consistently applied and consistent with the
Financial Statements and either remitted same to the legally constituted
authorities entitled to receive payment thereof or has reserved for same in its
accounts and an amount of cash equal to the amount of such reserve has been set
aside for payment thereof. Seller is not liable for any arrears of wages or any
taxes or penalties with respect to the foregoing. Seller has not entered into
and is not obligated to enter into any agreement relating to the payment of
vacation pay to any employee, and Seller does not have any obligation to any
employees to provide them with pay for vacation time other than as required by
generally applicable provisions of law. Seller has not received notice from any
employee of the Seller that any such employee is terminating his or her
employment with the Seller, nor to the best knowledge of the Seller does any
employee intend to terminate his or her employment with the Seller as a result
of the transactions contemplated hereby. There are no administrative charges or
court complaints pending or, to the knowledge of the Seller, threatened against
the Seller concerning alleged employment discrimination or any other matters
relating to the employment of labor. No trade union, counsel of trade unions,
employee bargaining agency or affiliated bargaining agent (i) holds bargaining
rights with respect to any of the employees of the Seller by way of
certification, interim certification,


                                      A-14

voluntary recognition, designation or successor right, (ii) has applied to be
certified as the bargaining agent of the employees of the Seller, or (iii) has
applied to have Seller declared a related employer pursuant to the provision of
applicable law. Except as set forth in Schedule 3.13, to the knowledge of the
Seller, no claim, injunction, fact, event or condition exists which would give
rise to a material claim by any employee or former employee (including
dependents and spouses thereof and other individuals covered thereunder) of the
Seller under any workers compensation laws, regulations, requirements or
programs.


     SECTION 3.14 Customers. Schedule 3.14 is a complete list by dollar volume
of billings (within the fiscal year ended December 31, 1998) of the Sellers'
customers. Except as set forth on Schedule 3.14, since December 31, 1998, none
of the customers who individually represent greater than 5% of the Seller's
billings has canceled or otherwise terminated, or, to the knowledge of the
Seller, threatened to cancel or otherwise terminate, its relationship with the
Seller or materially reduced, or to the knowledge of the Seller, threatened to
materially reduce, its business with the Seller. Seller has not received any
notice and has no knowledge or reason to believe that any customer who
individually represents more than 5% of either Seller's annual billings intends
to cancel or otherwise modify its relationship with Seller on account of the
transactions contemplated hereby or otherwise.


     SECTION 3.15 Interest of the Companies in Customers, etc. Except as set
forth in Schedule 3.15, Seller does not have any direct or indirect interest in
any competitor, supplier or customer of the Seller or in any person from whom
or to whom the Seller leases any real or personal property or in any other
person with whom the Seller has any business relationship. Schedule 3.15 also
describes, (i) all management, administrative, computer, telephone or other
services provided by any of the Seller's Affiliates, and all such services
provided by the Seller to any of such persons and entities, and (ii) all other
contracts, agreements, arrangements or transactions (including the purchase and
sale of inventory, supplies and other goods) between either Seller, on the one
hand, and any of such individuals or entities on the other hand, currently in
effect, including, without limitation any agreement or arrangement relating to
indebtedness to or from any of such individuals or entities, in each case
setting forth the terms thereof if not effected on an arm's-length basis.


     SECTION 3.16 Books and Records. All the books, records and accounts of
Seller are in all material respects accurate and complete, accurately reflect
in all material respects, all matters normally entered into the books, records
or accounts maintained by similar businesses, are in all material respects in
accordance with all laws, regulations and rules applicable to the Seller and
accurately present and reflect in all material respects all of the transactions
described therein. The Seller has accounting controls sufficient to ensure that
its transactions are in all material respects executed in accordance with its
management's general or specific authorization.


     SECTION 3.17 Insurance Policies. Schedule 3.17 is a correct and complete
list and description, including policy numbers, of all insurance policies owned
or held by the Seller or otherwise covering the Seller, its employees or
assets. Such policies are in full force and effect, and the Seller is not in
default under any of them. To the knowledge of the Seller, such insurance is of
the kind and in the amount not less than customarily obtained by corporations
or other entities of established reputation engaged in the same or similar
business and similarly situated. Seller has not received any notices of
non-renewal, cancellation or intent to cancel, not renew or increase premiums
or deductibles with respect to such insurance policies nor, to the knowledge of
the Seller, is there any basis for any such action. Schedule 3.17 also contains
a list of all pending claims with any insurance company (other than health,
medical and dental insurance claims of employees) and any instances within the
previous three years of a denial of coverage of the Seller by any insurance
company.


     SECTION 3.18 Bank Accounts. Schedule 3.18 contains a complete and correct
list of each bank and brokerage firm in which the Seller has an account or safe
deposit box, the number of each such account or box and the names of all
persons authorized to draw thereon or to have access thereto.


     SECTION 3.19 Compliance With Laws. Seller has complied with, is not in
violation of, and has not received any notices of violation with respect to,
any federal, state or local statute, law or regulation or any judgment, decree
or order of any Governmental Entity with respect to the conduct of its
business, or the ownership or operation of its business, except for failures to
comply or violations which, individually or in the aggregate, have not had and
are not reasonably likely to have a Seller Material Adverse Effect. Seller has
in effect all federal, state, local and foreign governmental approvals,
authorizations, certificates, filings, franchises,


                                      A-15
<PAGE>

notices, permits and rights ("Approvals") necessary for it to own lease or
operate its properties and assets and to carry on its business as now conducted
and there has occurred no default under any such Approval, or failure to obtain
such Approval, which would in the aggregate have a Seller Material Adverse
Effect.


     SECTION 3.20 Accounting and Tax Matters. To its knowledge, after
consulting with its tax advisors, neither Seller nor any of its Affiliates (as
defined in Section 6.10) has taken or agreed to take any action which would
prevent the Merger from constituting a transaction qualifying as a
reorganization under 368(a) of the Code.


     SECTION 3.21 Registration Statement; Proxy Statement/Prospectus. The
information to be supplied by Seller for inclusion in the proxy statement and
registration statement on Form S-4 pursuant to which shares of Buyer Common
Stock issued in the Merger will be registered under the Securities Act (the
"Registration Statement"), shall not at the time the Registration Statement is
filed with the SEC and at the time the Registration Statement is declared
effective by the SEC contain any untrue statement of a material fact or omit to
state any material fact required to be stated in the Registration Statement or
necessary in order to make the statements in the Registration Statement, in
light of the circumstances under which they were made, not misleading. The
information supplied by Seller for inclusion in the proxy statement/prospectus
to be sent to the stockholders of Seller in connection with the meeting of
Seller's stockholders to consider this Agreement and the Merger (the "Seller
Meeting") (the " Proxy Statement") shall not, on the date the Proxy Statement
is first mailed to stockholders of Seller, at the time of the Seller Meeting
and at the Effective Time, contain any statement which, at such time and in
light of the circumstances under which it shall be made, is false or misleading
with respect to any material fact, or omit to state any material fact necessary
in order to make the statements made in the Proxy Statement not false or
misleading; or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Seller Meeting which has become false or misleading. If at any
time prior to the Effective Time any event relating to Seller or any of its
Affiliates, officers or directors should be discovered by Seller which should
be set forth in an amendment to the Registration Statement or a supplement to
the Proxy Statement, Seller shall promptly inform Buyer. The Proxy Statement
will comply as to form in all material respects with the requirements of the
Exchange Act and the rules and regulations promulgated thereunder, except that
no representation is made by Seller with respect to statements made or
incorporated by reference therein based on information supplied by Buyer
specifically for inclusion or incorporation by reference in the Proxy
Statement.


     SECTION 3.22 Labor Matters. Seller is not a party to or otherwise bound by
any collective bargaining agreement, contract or other agreement or
understanding with a labor union or labor organization, nor, as of the date
hereof, is Seller the subject of any material proceeding asserting that Seller
has committed an unfair labor practice or is seeking to compel it to bargain
with any labor union or labor organization nor, as of the date of this
Agreement, is there pending or, to the knowledge of Seller, threatened, any
material labor strike, dispute, walkout, work stoppage, slow-down or lockout
involving Seller.


     SECTION 3.23 Year 2000 Compliance. The computer systems of Seller
(including, without limitation, all software, hardware, workstations and
related components, automated devices, embedded chips and other date sensitive
equipment such as security systems, alarms, elevators and HVAC systems) are
Year 2000 Compliant or will be Year 2000 Compliant by September 30, 1999,
except to the extent that any failure to be Year 2000 Compliant, either
individually or in the aggregate, would not have a Seller Material Adverse
Effect. The term "Year 2000 Compliant" as used herein means that the computer
systems are (i) capable of recognizing, processing, managing, representing,
interpreting, and manipulating correctly date related data for dates earlier
and later than January 1, 2000, including, but not limited to, calculating,
comparing, sorting, storing, tagging and sequencing, without resulting in or
causing logical or mathematical errors or inconsistencies in any user-interface
functionalities or otherwise, including data input and retrieval, data storage,
data fields, calculations, reports, processing, or any other input or output,
(ii) have the ability to provide data recognition for any data element without
limitation (including, but not limited to, date-related data represented
without a century designation, date-related data whose year is represented by
only two digits and date fields assigned special values), (iii) have the
ability to automatically function into and beyond the year 2000 without human
intervention and without any change in operations associated with the advent of
the year 2000, (iv) have the ability to correctly interpret data, dates and


                                      A-16
<PAGE>

time into and beyond the year 2000, (v) have the ability not to produce
noncompliance in existing information, nor otherwise corrupt such data into and
beyond the year 2000, (vi) have the ability to correctly process after January
1, 2000 data containing dates before that date, and (vii) have the ability to
recognize all "leap years," including February 29, 2000.

     Seller does not believe that the lack of ability of its computer systems
to properly interface with internal and external applications and systems of
third parties with whom the Seller exchanges data electronically (including
without limitation customers, clients, suppliers, service providers,
subcontractors, processors, converters, shippers, warehousemen, outsources,
data processors, regulatory agencies and banks) will have a Seller Material
Adverse Effect.

     SECTION 3.24 Legal Compliance. (a) Seller's manufacturing, distribution
and marketing practices are in compliance in all material respects with all
applicable federal and state laws, rules, regulations, orders, licenses,
judgments, writs, injunctions, decrees or demands, including, without
limitation, laws and regulations administered by the Food and Drug
Administration ("FDA") and the Drug Enforcement Administration ("DEA").

     (b) Seller possesses all material FDA new drug applications, abbreviated
new drug applications, and new animal drug applications as are currently

correct copies of which have been provided to the Buyer by the Seller.

     (c) Seller has not used the services of any person debarred under the
provisions of the Generic Drug Enforcement Act of 1992, 21 U.S.C.
ss. 335(a)(b). Neither the Seller, nor its respective officers, employees,
agents or affiliates, has been convicted of any crime or engaged in any conduct

and regulations of the FDA and the DEA to the extent such rules and regulations
are applicable to it, and each new drug application ("NDA") and abbreviated new
drug application ("ANDA") in which Seller has sold any product on or after
March 31, 1999, except where the failure to be in such compliance would not
have a Seller Material Adverse Effect. All manufacturing operations conducted
by or for the benefit of the Seller have been and are being conducted in
substantial compliance with the current Good Manufacturing Practice regulations
set forth in 21 C.F.R. Parts 210 and 211.

     (e) As to each drug of the Seller for which a NDA or ANDA has been

an untrue statement of material fact or fraudulent statement to the FDA or the
DEA, failed to disclose a material fact required to be disclosed to the FDA or
the DEA, or committed an act, made a statement, or failed to make a statement
that could reasonably be expected to provide a basis for the FDA to invoke its
policy respecting "Fraud, Untrue Statements of Material Facts, Bribery, and
Illegal Gratuities," set forth in 56 Fed. Reg 46191 (September 10, 1991).

     (h) The Seller has made available to Buyer copies of any and all notices
of inspectional observations (FD 483's), establishment inspection reports,
warning letters and any other documents received from or issued by the FDA or
the DEA within the last three years that indicate or suggest lack of compliance
with the FDA or the DEA regulatory requirements by the Seller, or persons
covered by product applications or otherwise performing services for the
benefit of the Seller.


                                      A-17
<PAGE>

     (i) Seller has not received any written notice that the FDA or the DEA has

such certification and such list was in each case true and accurate when made
and remained true and accurate thereafter.

     (l) Seller represents and warrants that all testing it has conducted or
has had conducted for it by third parties complies in all respects with the
requirements of Good Clinical Practice, Informed Consent, and all requirements
relating to protection of human subjects found in 21 C.F.R. ss. 50, and that
all nonclinical laboratory testing complies with the requirements of 21 C.F.R.
ss. 58.

     (m) As to each application or abbreviated application submitted to, but
not approved by, the FDA, and not withdrawn by the Seller, or applicants acting

warranties of the Seller set forth in this Agreement or any of the Transaction
Documents contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained herein or therein not
misleading. To the knowledge of the Seller, there is no material fact or
information which has not been disclosed to Buyer in writing which materially
adversely affects or could reasonably be anticipated to materially adversely
affect the business, condition (financial or otherwise), property or assets of
the Seller or the ability of the Seller to consummate the transactions
contemplated hereby.


                                   ARTICLE IV

                    REPRESENTATIONS AND WARRANTIES OF BUYER

     Buyer represents and warrants to Seller that the statements contained in
this Article IV are true and correct, except as set forth herein in the
disclosure schedule delivered by Buyer to Seller on or before the date of this
Agreement (the "Buyer Disclosure Schedules"). The Buyer Disclosure Schedules
shall be arranged in individual


                                      A-21
<PAGE>

schedules corresponding to the numbered paragraphs contained in this Article IV
and the disclosure in any schedules shall qualify other schedules in this
Article IV only to the extent that it is reasonably apparent from a reading of
such disclosure that it also qualifies or applies to such other schedules.
Without limiting the generality of the foregoing, the mere listing (or
inclusion of a copy) of a document or other item shall not be deemed adequate
to disclose an exception to a representation or warranty made herein (unless
the representation or warranty concerns the existence of the document or the
other item itself).


     SECTION 4.01 Organization of Buyer. Buyer is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation, has all requisite corporate power to own, lease and operate its
property and to carry on its business as now being conducted, and is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction in which the failure to be so qualified would have a material
adverse effect on the business, properties, financial condition or results of
operations of Buyer (a "Buyer Material Adverse Effect"); provided, however,
that for purposes of this Agreement, the following events shall not be taken
into account in determining whether there has been or would be a "Buyer
Material Adverse Effect" on or with respect to Buyer: (A) changes, events or
occurrences in the United States securities markets which are not specific to
Buyer, (B) changes, events or occurrences in the world economy which are not
specific to the Buyer, (C) the existence of this Agreement or the transactions
contemplated hereby or the announcement thereof, (D) any changes in GAAP, and
(E) changes, events or occurrences relating to the pharmaceutical industries in
general, and not specifically to Buyer. The Buyer does not own or control
(directly or indirectly), or own or hold any right to acquire, any stock,
partnership interest, joint venture interest, equity participation or other
security or interest in any other entity, corporation, partnership, trust or
any other business association. Except as set forth in the Buyer SEC Reports
(as defined in Section 4.04(a)) filed prior to the date hereof and with respect
to acquisitions of third parties of which Buyer advises Seller after the
closing thereof, Buyer does not directly or indirectly own any equity or
similar interest in, or any interest convertible into or exchangeable or
exercisable for, any corporation, partnership, joint venture or other business
association, or entity, excluding securities in any publicly traded company
held for investment by Buyer and comprising less than five percent (5%) of the
outstanding stock of such company.


     SECTION 4.02 Buyer Capital Structure. (a) The authorized capital stock of
Buyer consists of (i) 17,000,000 shares of Common Stock, par value $.01 per
share ("Buyer Common Stock"), (ii) 60,000 shares of Series A Convertible

50,000 shares of Series B Convertible Preferred Stock, par value $.01 per share
("Buyer Series B Preferred"), (iv) 9,000 shares of Series C Convertible
Preferred Stock, par value $.01 per share ("Buyer Series C Preferred"), (v)
50,000 shares of Series D Convertible Preferred Stock, par value $.01 per share
("Buyer Series D Preferred"). It is intended that prior to the Effective Time,
Buyer will file the amendment and restatement to its Certificate of
Incorporation referred to in Section 1.03 (ii) hereof, creating authorized
capital of 320,000 shares of Series 1 Convertible Preferred Stock, par value
$.01 per share ("Buyer Series 1 Preferred Stock"). As of June 30, 1999, there
were 7,254,053 shares of Buyer Common Stock, 9,000 shares of Buyer Series C
Preferred and 50,000 shares of Buyer Series D Preferred issued and outstanding,
all of which issued and outstanding shares are validly issued, fully paid and
nonassessable, and (ii) no shares of currently issued Common Stock of Buyer,
Buyer Series A Preferred, Buyer Series B Preferred, Buyer Series C Preferred
and Buyer Series D Preferred were held in the treasury of Buyer. Buyer Series A
Preferred, Buyer Series B Preferred, Buyer Series C Preferred, Buyer Series D
Preferred and Buyer Series 1 Preferred Stock are sometimes hereinafter
collectively referred to as "Buyer Preferred Stock Series". Schedule 4.02 shows
the ownership of the Buyer Common Stock and Buyer Preferred Stock Series by
officers, directors and all shareholders who own more than five percent (5%) of
the outstanding stock of the Seller. 832,837 shares of Buyer Common Stock are
reserved for future issuance pursuant to stock options granted and outstanding
as of June 30, 1999 under Buyer's 1995 Stock Incentive Plan (the "Buyer Stock
Plan"), 1,375,000 shares of Buyer Common Stock are reserved for future issuance
under warrants granted and outstanding as of June 30, 1999 ("Buyer Warrants")
and 2,950,000 shares of Buyer Common Stock are reserved for future issuance
upon conversion of outstanding shares of Buyer Series C Preferred and Buyer
Series D Preferred. No material change in such capitalization has occurred
between June 30, 1999 and the date of this Agreement. All shares of Buyer
Common Stock subject to issuance as specified above are duly authorized and,
upon issuance on the terms and conditions specified in the instruments pursuant
to which they are issuable, shall be validly issued, fully paid and
nonassessable. There are no bonds, debentures, notes or other indebtedness of
Buyer


                                      A-22
<PAGE>

having the right to vote (or convertible into securities having the right to
vote) on any matters on which shareholders of Buyer may vote. The shares of
Buyer Common Stock and Buyer Series 1 Preferred Stock to be issued in the
Merger will, when issued in accordance with the terms of this Agreement, be
validly issued, fully paid and nonassessable. Except with respect to the Buyer
Series 1 Preferred Stock, 9,000 shares of Buyer Series C Preferred and 50,000
shares of Buyer Series D Preferred, there are no obligations, contingent or
otherwise, of Buyer to repurchase, redeem or otherwise acquire any shares of
Buyer Common Stock or Buyer Preferred Stock Series, or to provide funds or to
make any material investment (in the form of a loan, capital contribution or
otherwise) in any other entity.

     (b) Except as set forth in this Section 4.02 or as reserved for future
grants of options under the Buyer Stock Plan, there are no equity securities of
any class of Buyer, or any security exchangeable into or exercisable or
convertible for such equity securities, issued, reserved for issuance or
outstanding. There are no options, warrants, equity securities, calls, rights,
commitments or agreements of any character to which Buyer is a party or by
which such entity is bound (including under letters of intent, whether binding
or nonbinding) obligating Buyer to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock of Buyer or other
equity interest of Buyer or obligating Buyer to grant, extend, accelerate the
vesting of, otherwise modify or amend or enter into any such option, warrant,
equity security, call, right, commitment or agreement except under the Buyer
Stock Plan or Buyer Warrants, or in connection with acquisitions. To the
knowledge of Buyer, there are no voting trusts, proxies or other voting
agreements or understandings with respect to the shares of capital stock of
Buyer or other equity interests of Buyer.

     SECTION 4.03 Authority; No Conflict; Required Filings and Consents. (a)
Buyer has all requisite corporate power and authority to enter into this
Agreement and to consummate the transactions contemplated by this Agreement.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated by this Agreement have been duly authorized by all
necessary corporate action on the part of Buyer subject only to the approval of
the Merger by Buyer's stockholders under the GCL; the vote of Buyer's
stockholders required to approve this Agreement and the Merger is a majority of
the outstanding shares of Buyer Common Stock and Buyer Preferred Stock Series
voting as a single class and a majority of the outstanding shares of Buyer
Series D Preferred voting as a single class on the record date for the Buyer
Meeting (as defined below) at which a quorum is present. This Agreement has
been duly executed and delivered by Buyer and constitutes the valid and binding
obligation of Buyer, enforceable against Buyer in accordance with its terms,
subject to the Bankruptcy and Equity Exception.

     (b) The execution and delivery of this Agreement by Buyer does not, and
the consummation of the transactions contemplated by this Agreement will not,
(i) conflict with, or result in any violation or breach of, any provision of
the Certificate of Incorporation or Bylaws of Buyer, (ii) result in any
violation or breach of, or constitute (with or without notice or lapse of time,
or both) a default (or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any material benefit) under, or
require a consent or waiver under, any of the terms, conditions or provisions
of any note, bond, mortgage, indenture, lease, contract or other agreement,
instrument or obligation to which Buyer is a party or by which any of its
properties or assets may be bound, or (iii) conflict with, violate, or cause
the termination of any permit, concession, franchise, license, judgment, order,
decree, statute, law, ordinance, rule or regulation applicable to Buyer or any
of its properties or assets, except in the case of (ii) and (iii) for any such
conflicts, violations, defaults, terminations, cancellations or accelerations
which are not, individually or in the aggregate, reasonably likely to have a
Buyer Material Adverse Effect.

     (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity or person or entity is
required by or with respect to Buyer in connection with the execution and
delivery of this Agreement or the consummation of the transactions contemplated
hereby, except as set forth on Schedule 4.03 or for (i) the filing of the
Registration Statement with the SEC in accordance with the Securities Act, (ii)
the filing of the Certificate of Merger with the Department of State of the
State of Delaware, (iii) such consents, approvals, orders, authorizations,
registrations, declarations and filings as may be required under applicable
state securities laws and the laws of any foreign country, (iv) the approval by
the Nasdaq SmallCap Market of the listing of the shares of Buyer Common Stock
to be issued in the transactions contemplated by this Agreement, and (v) such
other consents, authorizations, filings, approvals and registrations which, if
not obtained or made, would not interfere with the operation of any facility of
Buyer or otherwise be reasonably likely to have a Buyer Material Adverse
Effect.

     SECTION 4.04 SEC Filings; Financial Statements. (a) Since the date of its
initial public offering, Buyer has filed all forms, reports and documents,
including the exhibits thereto, required to be filed by Buyer with the SEC
under the Securities Act or the Exchange Act (these forms, reports and
documents are referred to collectively as "Buyer SEC Reports"). The Buyer SEC
Reports (i) at the time filed complied in all material respects with the
applicable requirements of the Securities Act and the Exchange Act, as the case
may be, and (ii) did not at the time they were filed (or if amended or
superseded by a filing prior to the date of this Agreement, then on the date of
such filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated in such Buyer SEC Reports or necessary in
order to make the statements in such Buyer SEC Reports, in the light of the
circumstances under which they were made, not misleading.

     (b) Each of the financial statements (including, in each case, any related
notes) contained in the Buyer SEC Reports is true, complete and correct in all
material respects, and complied as to form in all material respects with the
applicable published rules and regulations of the SEC with respect thereto, was
prepared in accordance with GAAP applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited statements, as permitted by Form 10-Q
of the SEC) and fairly presented the consolidated financial position of Buyer
as of the dates and the consolidated results of its operations and cash flows
for the periods indicated, except that the unaudited interim financial
statements were or are subject to normal and recurring year-end adjustments
which were not or are not expected to be material in amount. The unaudited
balance sheet of Buyer as of March 31, 1999 is referred to herein as the "Buyer
Balance Sheet."

     SECTION 4.05 No Undisclosed Liabilities. Except as disclosed in the Buyer

available at Nasdaq's website at http://www.nasdaq.com ("Buyer Releases") filed
prior to the date hereof, and except for normal or recurring liabilities
incurred since March 31, 1999 in the ordinary course of business consistent
with past practices, Buyer does not have any liabilities, either accrued,
contingent or otherwise (whether or not required to be reflected in financial
statements in accordance with GAAP), and whether due or to become due, which
individually or in the aggregate, are reasonably likely to have a Buyer
Material Adverse Effect.

     SECTION 4.06 Absence of Certain Changes or Events. Except as disclosed in
the Buyer SEC Reports filed prior to the date hereof or Buyer Releases, since
the date of the Buyer Balance Sheet, Buyer has conducted its businesses only in

results of operations, business or properties of Buyer that has had, or is
reasonably likely to have, a Buyer Material Adverse Effect; (ii) any damage,
destruction or loss (whether or not covered by insurance) with respect to Buyer

(iii) any material change by Buyer in its accounting methods, principles or
practices to which Seller has not previously consented in writing; (iv) any
revaluation by Buyer of any of its assets that has had, or is reasonably likely
to have, a Buyer Material Adverse Effect; or (v) any other action or event that
would have required the consent of Seller pursuant to Section 5.02 of this
Agreement had such action or event occurred after the date of this Agreement.

     SECTION 4.07 Taxes. Except as set forth on Schedule 4.07:

     (a) All Tax Returns required to be filed by or on behalf of Buyer have
been properly prepared and duly and timely filed with the appropriate taxing
authorities in all jurisdictions in which such Tax Returns are required to be
filed (after giving effect to any valid extensions of time in which to make
such filings), and all such Tax Returns were true, complete and correct in all
material respects.

     (b) All Taxes payable by or on behalf of Buyer or in respect of its
income, assets or operations (including interest and penalties) have been fully

have not yet been filed or for which Taxes are not yet due and owing.

     (c) Buyer has not executed or filed with any taxing authority any

including Buyer have been fully paid, and there are no other audits or
investigations by any taxing authority or proceedings in progress, nor has
Buyer received any written notice from any taxing authority that it intends to
conduct such an audit or investigation. No issue has been raised in writing by
a U.S. federal, state, local or foreign taxing authority in any current or
prior examination which, by application of the same or similar principles,
could reasonably be expected to result in a proposed deficiency for any
subsequent taxable period.


     (h) Neither Buyer, nor any other person on behalf of Buyer has (A) filed a
consent pursuant to Section 341(f) of the Code or agreed to have Section

agreed to or is required to make any adjustments pursuant to Section 481(a) of

accounting method, or has any application pending with any taxing authority

or foreign law with respect to Buyer, or (D) requested any extension of time
within which to file any Tax Return, which Tax Return has since not been filed.



     (i) No property owned by Buyer is (A) property required to be treated as
being owned by another Person pursuant to the provisions of Section 168(f)(8)
of the Internal Revenue Code of 1954, as amended and in effect immediately

or (C) is "tax-exempt bond financed property" within the meaning of Section
168(g) of the Code.


     (j) Buyer is not a party to any tax sharing or similar agreement or
arrangement (whether or not written) pursuant to which it will have any
obligation to make any payments after the Closing.


     (k) There is no contract, agreement, plan or arrangement covering any

     (l) Buyer has substantial authority for the treatment of or has disclosed
(in accordance with Section 6662(d)(2)(B)(ii) of the Code) on its federal

Revenue Service or comparable rulings of other taxing authorities.

                                      A-25
<PAGE>

     (p) Buyer has never been a member of any Affiliated Group for tax

within the meaning of Section 897(c)(2) of the Code during the applicable

as defined in any applicable Tax treaty or convention.

     SECTION 4.08 Agreements, Contracts and Commitments. Except as delivered to

commitments that are required to be filed as an exhibit under subheading (10) -
Material Contracts of Item 601 of Regulation S-B of the federal securities laws
and the rules and regulations thereunder. The Buyer has not entered into and is
not bound by any material contract, agreement, relationship or commitment,
written or oral, including without limitation, any obligations for money
borrowed or under leases other than those identified on Schedule 4.08 ("Buyer
Material Contracts"). Buyer is not in default, and no event has occurred which
with the giving of notice or the passage of time or both would constitute a
default by the Buyer or, to the best of Buyer's knowledge, any other party
under any Buyer Material Contract or any other material obligation owed by
Buyer and, to the best of Buyer's knowledge, no event has occurred which with
the giving of notice or the passage of time or both would constitute a default
by any other party to any such Buyer Material Contract or obligation. Each
Buyer Material Contract that has not expired, by its terms is in full force and
effect, and no party to any of the Buyer Material Contracts will have the right
to terminate such contract as a result of the transactions contemplated by this
Agreement. Except for employment agreements, none of the Buyer Material
Contracts is currently being renegotiated in any material respect, and Buyer
has no knowledge that any Buyer Material Contract will be subject to a
voluntary or regulatory ordered renegotiation within 12 months after the date

relationship or commitment, whether or not deemed material, which in any way
restricts or purports to restrict the ability of Buyer to acquire any property
or assets or conduct its business or provide services to any person or entity
anywhere in the world.

     SECTION 4.09 Litigation. Except as set forth on Schedule 4.09, there is no
claim, counter-claim, action, suit, order, proceeding or investigation pending
or to the knowledge of the Buyer, threatened against or involving the Buyer, or
pending or, to the knowledge of the Buyer, threatened against any of its
officers, directors or key employees of the Buyer with respect to business
activities on behalf of the Buyer with respect to or affecting the Buyer, its
accounts, business, properties, assets or rights, or relating to the
transactions contemplated hereby, before any court, agency, regulatory,
administrative or other governmental body or officer or before any arbitrator,
nor, to the knowledge of the Buyer, is there any reasonable basis for any such
claim, action, suit, proceeding or governmental, administrative or regulatory
investigation. The Buyer is not directly subject to or affected by any order,
judgment, decree or ruling of any court or governmental agency. The Buyer has
not received any written opinion or memorandum of legal advice from legal
counsel to the effect that any of them are exposed to any liability which may
be material to the business, prospects, results of operations, financial
condition or assets of the Buyer. Except as set forth on Schedule 4.09, the
Buyer is not engaged in any legal action to recover monies due it or for
damages sustained by it, and none of the assets of the Buyer nor any of their
respective business practices are in any manner, directly or indirectly,
affected by injunction of any court or governmental, administrative or
regulatory agency, body or officer.

     SECTION 4.10 Compliance With Laws. Buyer has complied with, is not in
violation of, and has not received any notices of violation with respect to,
any federal, state or local statute, law or regulation or any judgment, decree
or order of any Governmental Entity with respect to the conduct of its
business, or the ownership or operation of its business, except for failures to
comply or violations which, individually or in the aggregate, have not had and
are not reasonably likely to have a Buyer Material Adverse Effect. Buyer has
all Approvals necessary for it to own, lease or operate its properties and to
carry on its business as now conducted and there has occurred no default under
any such Approval, or failure to obtain such Approval, which would in the
aggregate have a Buyer Material Adverse Effect.


                                      A-26
<PAGE>

     SECTION 4.11 Accounting and Tax Matters. To its knowledge, after
consulting with its tax advisors, neither Buyer nor any of its Affiliates has
taken or agreed to take any action which would prevent the Merger from
constituting a transaction qualifying as a reorganization under Section 368(a)
of the Code.

     SECTION 4.12 Registration Statement; Proxy Statement/Prospectus. The
information in the Registration Statement (except for information supplied by
Seller for inclusion in the Registration Statement, as to which Buyer makes no
representation) shall not at the time the Registration Statement is filed with
the SEC and at the time the Registration Statement is declared effective by the
SEC contain any untrue statement of a material fact or omit to state any
material fact required to be stated in the Registration Statement or necessary
in order to make the statements in the Registration Statement, in light of the
circumstances under which they were made, not misleading. The information
supplied by Buyer for inclusion in the Proxy Statement shall not, on the date
the Proxy Statement is first mailed to stockholders of Seller, at the time of
the Seller Meeting, or to the stockholders of Buyer in connection with the
meeting of Buyer's stockholders to consider this Agreement and Plan of Merger
(the "Buyer Meeting") and at the Effective Time, contain any statement which,
at such time and in light of the circumstances under which it shall be made, is
false or misleading with respect to any material fact, or omit to state any
material fact necessary in order to make the statements made in the Proxy
Statement not false or misleading; or omit to state any material fact necessary
to correct any statement in any earlier communication with respect to the
solicitation of proxies for the Seller Meeting or Buyer Meeting which has
become false or misleading. If at any time prior to the Effective Time any
event relating to Buyer or any of its Affiliates, officers or directors should
be discovered by Buyer which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement, Buyer shall
promptly inform Seller. The Registration Statement will comply as to form in
all material respects with the requirements of the Securities Act and the rules
and regulations promulgated thereunder, except that no representation is made
by Buyer with respect to statements made or incorporated by reference therein
based on information supplied by Seller specifically for inclusion or
incorporation by reference in the Registration Statement.

     SECTION 4.13 Year 2000 Compliance. The computer systems of Buyer
(including, without limitation, all software, hardware, workstations and
related components, automated devices, embedded chips and other date sensitive
equipment such as security systems, alarms, elevators and HVAC systems) are
Year 2000 Compliant or will be Year 2000 Compliant by September 30, 1999,
except to the extent that any failure to be Year 2000 Compliant, either
individually or in the aggregate, would not have a Buyer Material Adverse
Effect. The term "Year 2000 Compliant" as used herein means that the computer
systems are (i) capable of recognizing, processing, managing, representing,
interpreting, and manipulating correctly date related data for dates earlier
and later than January 1, 2000, including, but not limited to, calculating,
comparing, sorting, storing, tagging and sequencing, without resulting in or
causing logical or mathematical errors or inconsistencies in any user-interface
functionalities or otherwise, including data input and retrieval, data storage,
data fields, calculations, reports, processing, or any other input or output,
(ii) have the ability to provide data recognition for any data element without
limitation (including, but not limited to, date-related data represented
without a century designation, date-related data whose year is represented by
only two digits and date fields assigned special values), (iii) have the
ability to automatically function into and beyond the year 2000 without human
intervention and without any change in operations associated with the advent of
the year 2000, (iv) have the ability to correctly interpret data, dates and
time into and beyond the year 2000, (v) have the ability not to produce
noncompliance in existing information, nor otherwise corrupt such data into and
beyond the year 2000, (vi) have the ability to correctly process after January
1, 2000 data containing dates before that date, and (vii) have the ability to
recognize all "leap years," including February 29, 2000.

     The computer systems of Buyer have the ability to properly interface and
will continue to properly interface with internal and external applications and
systems of third parties with whom Buyer exchanges data electronically
(including without limitation customers, clients, suppliers, service providers,
subcontractors, processors, converters, shippers, warehousemen, outsources,
data processors, regulatory agencies and banks) whether or not they have
achieved Year 2000 Compliance.

     SECTION 4.14  [Reserved].

     SECTION 4.15 Legal Compliance. (a) Buyer's manufacturing, distribution and
marketing practices are in compliance in all material respects with all
applicable federal and state laws, rules, regulations, orders, licenses,
judgments, writs, injunctions, decrees or demands, including, without
limitation, laws and regulations administered by the FDA and the DEA.

     (b) Buyer possesses all material FDA new drug applications, abbreviated

being referred to in this Agreement as a "Seller Acquisition Proposal");
provided, however, that if the Board of Directors of Seller determines in good
faith, based on the advice of outside counsel and of an investment banker, that

response to a written Seller Acquisition Proposal that (i) was unsolicited or
that did not otherwise result from a breach of this section, and (ii) is more
favorable, as determined by the Board of Directors in good faith, than the
transaction contemplated by this Agreement (a "Seller Superior Proposal"), may

Seller Acquisition Proposal pursuant to a customary confidentiality agreement
and (y) participate in negotiations regarding such Seller Acquisition Proposal.
The term "Substantial" as used in this Section 6.01 means (i) 10% or more of

the Merger unless there is a Seller Superior Proposal outstanding, (2) approve
or recommend, or propose to approve or recommend, a Seller Acquisition Proposal
that is not a Seller Superior Proposal or (3) cause Seller to enter into any
letter of intent, agreement in principle or other agreement with respect to a
Seller Acquisition Proposal unless, in the case of (3), the Board of Directors
of Seller (x) shall have determined in good faith, based on the advice of
outside counsel, that failure to do so would be reasonably likely to constitute
a breach of its fiduciary duties to Seller's stockholders under applicable law,
(y) shall then terminate this Agreement pursuant to the termination provisions
of Section 8.01 and (z) shall then pay to Buyer the fees and expenses set forth
in Section 8.03.

     (b) Seller shall notify Buyer immediately after receipt by Seller (or its
advisors) of any Seller Acquisition Proposal or any request for information in

books or records of Seller by any person or entity that informs Seller that it
is considering making, or has made, a Seller Acquisition Proposal. Such notice
shall be made orally and in writing and shall indicate in reasonable detail the
identity of the offeror and the terms and conditions of such proposal, inquiry
or contact.

response to a written Buyer Acquisition Proposal that (i) was unsolicited or
that did not otherwise result from a breach of this section, and (ii) is more
favorable, as determined by the Board of Directors in good faith, than the
transaction contemplated by this Agreement (a "Buyer Superior Proposal"), may

agreement and (y) participate in negotiations regarding such Buyer Acquisition
Proposal. The term "Substantial" as used in this Section 6.02 means (i) 10% or

Indemnified Party shall only be entitled to indemnification pursuant to Section

Party shall be entitled to seek indemnification for all indemnification claims
from the first dollar of Damages; (ii) the indemnification obligations of the
Seller Stockholders pursuant to Section 9.03(a) hereof shall be limited to the
amount deposited by the Seller Stockholders into the Escrow and the Buyer
Indemnities shall not be entitled to pursue any claims for indemnification
against the Seller Stockholders directly or personally and the sole recourse of
the Buyer Indemnities shall be to make claims against the Escrow in accordance

Indemnified Party shall have the right, at its own expense to participate in

Claim.

     SECTION 9.06 Subrogation. The Indemnifying Party shall not be entitled to
require that any action be brought against any other person before action is

subrogated to any right of action until it has paid in full or successfully
defended against the Third Party Claim for which indemnification is sought.

     SECTION 9.07 Indemnification Claims Procedures. (a) Promptly following the
receipt of notice by an Indemnified Party of a Third Party Claim which the
Indemnified Party believes may result in a demand against the Escrow or the
Reserved Shares, as the case may be, the Indemnified Party shall notify the
Indemnifying Party (which may be the Seller Stockholder Agent, in the case of
notification to the Seller Indemnitees) of such claim in accordance with the
provisions of the Escrow Agreement. The party receiving the notice of the Third
Party Claim shall notify the other party hereto of such Third Party Claim. The
failure to give such notice shall not relieve the Indemnifying Party of its
obligations under this Agreement except to the extent that the Indemnifying
Party is substantially prejudiced as a result of the failure to give such
notice. Within fifteen (15) business days after receipt of the notice by the
Indemnifying Party pursuant to the preceding sentence, the Indemnifying Party
shall notify the Indemnified Party whether it elects to control the defense of
the Third Party Claim and whether it believes, in good faith, that it has
justifiable cause to contest its obligation to indemnify the Indemnified Party
in respect to the claims asserted therein (and if so, the justification
therefor). If the Indemnifying Party elects to undertake the defense of such
Third Party Claim, it shall do so at its own expense with counsel of its own
choosing, without prejudice to the right of the Indemnifying Party thereafter
to contest its obligation to indemnify the Indemnified Party in respect to the
claims asserted therein. If the Indemnifying Party elects not to defend the
Third Party Claim or fails to pursue such Third Party Claim diligently, the
Indemnified Party shall have the right to undertake, conduct and control the
defense of such Third Party Claim through counsel of its own choosing. If the
Indemnified Party elects to undertake and control the defense in accordance
with this Section 9.07, the Indemnified Party may defend against such claim or
litigation in such manner as it may deem appropriate, including, but not
limited to, settling such claim or litigation, after giving notice of the same
to the Indemnifying Party, on such terms as the Indemnified Party may deem
appropriate. In any action by the Indemnified Party seeking indemnification
from the Indemnifying Party in accordance with the provisions of this Section
9.07(a), the Indemnifying Party shall not be entitled to question the manner in
which the Indemnified Party defended such claim or litigation or the amount of
or nature of any such settlement. Notwithstanding the foregoing, the
Indemnifying Party shall not forfeit its right to contest its obligation to
indemnify hereunder by not defending the party who may be entitled to such
indemnification. The party that litigates or contests the Third Party Claim
shall keep the other party fully advised of the progress and disposition of
such claim.

     (b) In the event the Indemnifying Party elects not to undertake the
defense of the Third Party Claim or fails to pursue diligently the defense of
such a claim and the Indemnified Party litigates or otherwise contests or
settles the Third Party Claim, then, provided that a final determination has
been made that the Indemnified Party is entitled to indemnification hereunder,
the Indemnifying Party shall promptly reimburse the Indemnified Party for all
amounts paid to settle such claim or all amounts paid in satisfaction of a
judgment against the Indemnified party in contesting such claim and in
providing its right to indemnification hereunder, all in accordance with the
provisions of this Article IX. Notwithstanding the foregoing, no settlement of
any Third Party Claim without the prior written consent of the Indemnifying
Party shall be determinative of the validity of any claim that the Indemnified
Party is entitled to indemnification hereunder.

     (c) No Third Party Claim will be settled by the Indemnifying Party without
the prior written consent of the Indemnified Party, which consent will not be
unreasonably withheld; provided, however, that if such claim asserts that the
Indemnifying Party is jointly and severally liable and the Indemnified Party
shall be fully released from all liability relating to such third Party Claim
in connection with such settlement, the Indemnifying Party shall not be
required to obtain the consent of the Indemnified Party. If, however, the
Indemnified party refuses to consent to a bona fide offered settlement which
the Indemnifying party wishes to accept, the Indemnified Party may continue to
pursue such Third Party Claim free of any participation by the Indemnifying
Party, at the sole expense of the Indemnified Party. In such event, the
Indemnifying Party shall pay to the Indemnified Party the amount of the offer
of settlement which the Indemnified Party refused to accept, plus the costs and
expenses incurred by the Indemnified Party prior to the date the Indemnifying
Party notifies the Indemnified Party of the offer of settlement, all in
accordance with the terms of this Article IX, and, upon the payment or receipt
of such


                                      A-52

amount, as the case may be, the Indemnifying Party shall have no further
liability with respect to such Third Party Claim. The Indemnifying party shall
be entitled to recover from the Indemnified Party any additional expenses
incurred by such Indemnifying Party as a result of the decision of the
Indemnified Party to pursue the matter.

     (d) The Seller Stockholders and Seller hereby acknowledge and agree that
the Seller Stockholders will control the Surviving Corporation after the
Merger. Such parties further acknowledge and agree that the indemnification
rights set forth in Section 9.03(a) shall be for the benefit of all
stockholders of the Buyer and the Surviving Corporation and the duties and
responsibilities of the foregoing parties with respect to the Surviving
Corporation are to act in the best interest of all shareholders of the
Surviving Corporation.

     SECTION 9.08 Seller Stockholder Agent. (a) In the event that the Merger is
approved, effective upon such vote, and without further act of any Seller
Stockholder, a committee (the "Committee") consisting of Dr. Larry Hsu and Dr.
Charles Hsiao shall be appointed as agents and attorneys-in-fact (collectively,
the "Seller Stockholder Agent") for each Seller Stockholder (except such Seller
Stockholders, if any, as shall have perfected their dissenter rights under
applicable law). The Seller Stockholder Agent, for and on behalf of Seller
Stockholders, shall have the power to take any and all actions required to be
taken by the Seller Stockholders pursuant to this Agreement or the Escrow
Agreement including, without limitation, the power to give and receive notices
and communications, to enter into and perform the Escrow Agreement, to make
claims for indemnification against Buyer, to authorize delivery to Buyer of
Buyer Common Stock or Preferred Stock or other property from the Escrow Fund in
satisfaction of claims by Buyer, to object to such deliveries, to agree to
negotiate, enter into settlements and compromises of, and demand arbitration
and comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary appropriate or in the judgment of
Seller Stockholder Agent for the accomplishment of the foregoing. The Seller
Stockholder Agent shall act by unanimous vote or unanimous written action or
consent of the members of the Committee. Effective upon the approval of this
Agreement by the Seller Stockholders, the Seller Stockholders individually
shall have no power or authority to take any actions against Buyer or otherwise
pursuant to this Agreement or the Escrow Agreement, and all actions of the
Seller Stockholders, whether pursuant to this Agreement or the Escrow
Agreement, must be taken solely by the Seller Stockholder Agent.

     (b) Buyer shall have no liability of any kind to any Seller Stockholder as
a result of or arising out of any action taken or not taken by the Seller
Stockholder Agent at any time under this Agreement or the Escrow Agreement and
each Seller Stockholder hereby releases Buyer from any such liability. Buyer
may conclusively rely, without any obligation of investigation or inquiry of
any kind, on any action taken by the Seller Stockholder Agent as having been
fully authorized and approved by all necessary action by each Seller
Stockholder (except such Seller Stockholders, if any, as shall have perfected
their dissenter rights under applicable law).

The Board of Directors
Global Pharmaceutical Corporation
Castor & Kensington Avenues
Philadelphia, PA 19124

Gentlemen:

     We understand that Global Pharmaceutical Corporation, a Delaware
corporation ("Global") and Impax Pharmaceuticals, Inc., a California
Corporation ("Impax") are proposing to enter into an Agreement and Plan of
Merger (the "Agreement") pursuant to which Impax will be merged with and into
Global (the "Merger") with Global as the surviving corporation (the "Proposed
Transaction"). Capitalized terms used herein and not otherwise defined shall
have the meaning assigned such terms in the Agreement. In the Merger, (i) each
holder of Common Stock, no par value per share of Impax, and each holder of
Series A and Series B Preferred Stock of Impax shall receive, in each case,
3.3358 shares of Common Stock, par value $0.01 per share of Global (the "Global
Common Stock") for each such share of Common Stock, Series A Preferred Stock or
Series B Preferred Stock, respectively, (ii) each holder of Series C Preferred
Stock of Impax will receive 5.8490 Shares of Global Common Stock for each such
share of Series C Preferred Stock, and (iii) each holder of Series D Preferred
Stock of Impax will receive .0500 shares of Series 1 Preferrred Stock of Global
("Global Series 1 Preferred Stock") for each such share of Series D Preferred
Stock. The Global Common Stock and the Global Series 1 Preferred Stock to be
received by shareholders of Impax in the Merger shall be referred to herein as
the "Consideration."

     You have requested our opinion, as investment bankers, as to the fairness,
from a financial point of view, to the holders of Global Common Stock of the
Consideration. Our opinion addresses only the fairness, from a financial point
of view, of the Consideration, and we do not express any views on any other
terms of the Proposed Transaction. Specifically, we have not been requested to
opine as to, and our opinion does not in any manner address, Global's
underlying business decision to proceed with or affect the Proposed
Transaction.

     In arriving at our opinion we have:

     (i)    reviewed a draft of the Agreement dated July 20, 1999 and, for
            purposes hereof, we have assumed that the final form thereof will
            not differ in any material respect from such draft;

     (ii)   held discussions with members of senior management of Global and
            Impax regarding their respective past and current business
            operations and their financial conditions and future prospects;

     (iii)  reviewed historical financial and business information provided to
            us by the management of Global and the management of Impax;

     (iv)   reviewed internally prepared financial projections of Global and
            Impax furnished to us by the management of Global and the management
            of Impax;

     (v)    reviewed the historical stock prices and trading volumes of the
            Global Common Stock;

     (vi)   reviewed certain historical financial and operating data of public
            companies whose business we consider comparable to that of each of
            Global and Impax;

     (vii)  reviewed the financial terms, to the extent publicly available, of
            certain transactions which we considered comparable to the Proposed
            Transaction;

     (viii) performed discounted cash flow analyses of Global and Impax based
            upon certain assumptions of future performance provided to us by
            management of Global and management of Impax;

     (ix)   conducted such other analyses and reviewed such other information as
            we deemed appropriate.

                                      B-1

     Gruntal, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, distributions of listed and
unlisted securities, private placements and financial valuations for corporate
purposes. In addition, in the ordinary course of our business, Gruntal may
actively trade the Global Common Stock for Gruntal's account and for the
accounts of customers, and accordingly, may at any time hold a long or short
position in such security.

     In the course of our review, we have relied upon and assumed the accuracy
and completeness of all the information furnished to us by Global and Impax and
have not attempted an independent verification thereof. We have not made nor
obtained any independent evaluations or appraisals of the assets or liabilities
of Impax or Global, including, but not limited to, liabilities arising from or
connected with any pending or future litigation to which Global or Impax is or
may become a party. With respect to the financial projections furnished to us
or discussed by us with the management of Global and Impax, we have assumed
that they have been reasonably prepared and reflect the best currently
available estimates and judgement of Global's and Impax's management as to the
expected future results of operations, synergies and financial condition of
Global and Impax to which such analyses and forecasts relate, and we have
assumed that such expected future results of operations, synergies and
strategic benefits will be realized as described by such management. The
inability of Global and Impax to realize such expected future results of
operations, synergies and strategic benefits could affect the opinion herein,
and we express no view as to whether such future results of operations,
synergies and strategic benefits will actually be realized. We have also
assumed that the transaction will have the tax consequences described in the
Agreement and in discussions with, and other materials furnished to us by,
representatives of Global.

     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments including, without
limitation, any changes to the terms or conditions of the Proposed Transaction
may affect this opinion and that we do not have any obligation to update,
revise, or reaffirm this opinion. We are expressing no opinion herein as to the
price at which Global Common Stock or the Global Series 1 Preferred Stock will
trade at any future date. We have also assumed that in the course of obtaining
the necessary regulatory or other consents or approvals (contractual or
otherwise) for the Proposed Transaction, no material restrictions, including
any divestiture requirements or amendments or modifications to the Proposed
Transaction, will be imposed.

     Based upon and subject to the foregoing, including the various assumptions
and limitations set forth herein, we are of the opinion that, as of the date
hereof, the Consideration is fair, from a financial point of view, to the
holders of Global Common Stock.

     This opinion is for the use and benefit of the Board of Directors of
Global in connection with and for the purpose of its evaluation of the Proposed
Transaction. This opinion does not constitute a recommendation to engage in the
Proposed Transaction or a recommendation to any shareholder of Global as to how
such shareholder should vote on the Proposed Transaction or any matter related
thereto.

                                        Very truly yours,


                                        [SIGNATURE OMITTED]

Gentlemen:

On July 26, 1999 Gruntal & Co., L.L.C. expressed its opinion (the "Opinion")
that the Consideration is fair, from a financial point of view, to the holders
of Global Common Stock. In affirming the Opinion we have reviewed the Opinion
and its supporting materials and such other matters as we have deemed relevant.
We reviewed the final merger agreement dated July 26, 1999 between Global and
Impax. All terms used and not defined herein have the meaning set forth in the
Opinion.

Following the above review, as of the date hereof, we affirm the Opinion.




                                                  Very truly yours,

                                                  GRUNTAL & CO., L.L.C.

     262 APPRAISAL RIGHTS.--(a) Any stockholder of a corporation of this State
who holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation,
who has otherwise complied with subsection (d) of this section and who has
neither voted in favor of the merger or consolidation nor consented thereto in
writing pursuant to ss. 228 of this title shall be entitled to an appraisal by
the Court of Chancery of the fair value of the stockholder's shares of stock
under the circumstances described in subsections (b) and (c) of this section.
As used in this section, the word "stockholder" means a holder of record of
stock in a stock corporation and also a member of record of a nonstock
corporation; and the words "stock" and "share" mean and include what is
ordinarily meant by those words and also membership or membership interest of a
member of a nonstock corporation; and the words "depository receipt" mean a
receipt or other instrument issued by a depository representing an interest in
one or more shares, or fractions thereof, solely of stock of a corporation,
which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to ss. 251 (other than a merger effected pursuant to
ss. 251(g) of this title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or
ss. 264 of this title:

     (1) Provided, however, that no appraisal rights under this section shall
be available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did
not require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of ss. 251 of this title.

     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to ss.ss. 251, 252,
254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

     a. Shares of stock of the corporation surviving or resulting from such
merger or consolidation, or depository receipts in respect thereof;

     b. Shares of stock of any other corporation, or depository receipts in
respect thereof, which shares of stock (or depository receipts in respect
thereof) or depository receipts at the effective date of the merger or
consolidation will be either listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or held of
record by more than 2,000 holders;

     c. Cash in lieu of fractional shares or fractional depository receipts
described in the foregoing subparagraphs a. and b. of this paragraph; or

     d. Any combination of the shares of stock, depository receipts and cash in
lieu of fractional shares or fractional depository receipts described in the
foregoing subparagraphs a., b. and c. of this paragraph.

     (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under ss. 253 of this title is not owned by the
parent corporation immediately prior to the merger, appraisal rights shall be
available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.


                                      C-1
<PAGE>

     (d) Appraisal rights shall be perfected as follows:


     (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting,
shall notify each of its stockholders who was such on the record date for such
meeting with respect to shares for which appraisal rights are available
pursuant to subsections (b) or (c) hereof that appraisal rights are available
for any or all of the shares of the constituent corporations, and shall include
in such notice a copy of this section. Each stockholder electing to demand the
appraisal of such stockholder's shares shall deliver to the corporation, before
the taking of the vote on the merger or consolidation, a written demand for
appraisal of such stockholder's shares. Such demand will be sufficient if it
reasonably informs the corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of 1such stockholder's
shares. A proxy or vote against the merger or consolidation shall not
constitute such a demand. A stockholder electing to take such action must do so
by a separate written demand as herein provided. Within 10 days after the
effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or


     (2) If the merger or consolidation was approved pursuant to ss. 228 or
ss. 253 of this title, each constituent corporation, either before the
effective date of the merger or consolidation or within ten days thereafter,
shall notify each of the holders of any class or series of stock of such
constituent corporation who are entitled to appraisal rights of the approval of
the merger or consolidation and that appraisal rights are available for any or
all shares of such class or series of stock of such constituent corporation,
and shall include in such notice a copy of this section; provided that, if the
notice is given on or after the effective date of the merger or consolidation,
such notice shall be given by the surviving or resulting corporation to all
such holders of any class or series of stock of a constituent corporation that
are entitled to appraisal rights. Such notice may, and, if given on or after
the effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or
resulting corporation shall send such a second notice to all such holders on or
within 10 days after such effective date; provided, however, that if such
second notice is sent more than 20 days following the sending of the first
notice, such second notice need only be sent to each stockholder who is
entitled to appraisal rights and who has demanded appraisal of such holder's
shares in accordance with this subsection. An affidavit of the secretary or
assistant secretary or of the transfer agent of the corporation that is
required to give either notice that such notice has been given shall, in the
absence of fraud, be prima facie evidence of the facts stated therein. For
purposes of determining the stockholders entitled to receive either notice,
each constituent corporation may fix, in advance, a record date that shall be
not more than 10 days prior to the date the notice is given, provided, that if
the notice is given on or after the effective date of the merger or
consolidation, the record date shall be such effective date. If no record date
is fixed and the notice is given prior to the effective date, the record date
shall be the close of business on the day next preceding the day on which the
notice is given.


     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who
has complied with subsections (a) and (d) hereof and who is otherwise entitled
to appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms
offered upon the merger or consolidation. Within 120 days after the effective
date of the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of


                                      C-2
<PAGE>

the merger or consolidation and with respect to which demands for appraisal
have been received and the aggregate number of holders of such shares. Such
written statement shall be mailed to the stockholder within 10 days after such
stockholder's written request for such a statement is received by the surviving
or resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.


     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.


     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.


     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court may,
in its discretion, permit discovery of other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection (f)
of this section and who has submitted such stockholder's certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that such stockholder is not
entitled to appraisal rights under this section.


     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.


     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.


     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose


                                      C-3
<PAGE>

or to receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall
deliver to the surviving or resulting corporation a written withdrawal of such
stockholder's demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.

     (1) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation. (Last amended by Ch.
339, L. '98, eff. 7-1-98.)

                        CHAPTER 13. DISSENTERS' RIGHTS


     1300 [SHORT FORM MERGER; PURCHASE OF SHARES AT FAIR MARKET VALUE;
"DISSENTING SHARES" AND DISSENTING SHAREHOLDER].-- (a) If the approval of the
outstanding shares (Section 152) of a corporation is required for a
reorganization under subdivisions (a) and (b) or subdivision (e) or (f) of
Section 1201, each shareholder of the corporation entitled to vote on the
transaction and each shareholder of a subsidiary corporation in a short-form
merger may, by complying with this chapter, require the corporation in which
the shareholder holds shares to purchase for cash at their fair market value
the shares owned by the shareholder which are dissenting shares as defined in
subdivision (b). The fair market value shall be determined as of the day before
the first announcement of the terms of the proposed reorganization or
short-form merger, excluding any appreciation or depreciation in consequence of
the proposed action, but adjusted for any stock split, reverse stock split, or
share dividend which becomes effective thereafter.

     (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

     (1) Which were not immediately prior to the reorganization or short-form
merger either (A) listed on any national securities exchange certified by the
Commissioner of Corporations under subdivision (o) of Section 25100 or (B)
listed on the list of OTC margin stocks issued by the Board of Governors of the
Federal Reserve System, and the notice of meeting of shareholders to act upon
the reorganization summarizes this section and Sections 1301, 1302, 1303 and
1304; provided, however, that this provision does not apply to any shares with
respect to which there exists any restriction on transfer imposed by the
corporation or by any law or regulation; and provided, further, that this
provision does not apply to any class of shares described in subparagraph (A)
or (B) if demands for payment are filed with respect to 5 percent or more of
the outstanding shares of that class.

     (2) Which were outstanding on the date for the determination of
shareholders entitled to vote on the reorganization and (A) were not voted in
favor of the reorganization or, (B) if described in subparagraph (A) or (B) of
paragraph (1) (without regard to the provisions in that paragraph), were voted
against the reorganization, or which were held of record on the effective date
of a short-form merger; provided, however, that subparagraph (A) rather than
subparagraph (B) of this paragraph applies in any case where the approval
required by Section 1201 is sought by written consent rather than at a meeting.


     (3) Which the dissenting shareholder has demanded that the corporation
purchase at their fair market value, in accordance with Section 1301.

     (4) Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record. (Last
amended by Ch. 543, L. '93, eff. 1-1-94.)

     1301 [DISSENTER'S RIGHTS; DEMAND ON CORPORATION FOR PURCHASE OF SHARES].--
(a) If, in the case of a reorganization, any shareholders of a corporation have
a right under Section 1300, subject to compliance with paragraphs (3) and (4)
of subdivision (b) thereof, to require the corporation to purchase their shares
for cash, such corporation shall mail to each such shareholder a notice of the
approval of the reorganization by its outstanding shares (Section 152) within
10 days after the date of such approval, accompanied by a copy of Sections
1300, 1302, 1303, 1304 and this section, a statement of the price determined by
the corporation to represent the fair market value of the dissenting shares,
and a brief description of the procedure to be followed if the shareholder
desires to exercise the shareholder's right under such sections. The statement
of price constitutes an offer by the corporation to purchase at the price
stated any dissenting shares as defined in subdivision (b) of Section 1300,
unless they lose their status as dissenting shares under Section 1309.

     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance
with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares


                                      D-1
<PAGE>

described in clause (i) or (ii) of paragraph (1) of subdivision (b) of Section
1300 (without regard to the provisos in that paragraph), not later than the
date of the shareholder's meeting to vote upon the reorganization, or (2) in
any other case within 30 days after the date on which the notice of the
approval by the outstanding shares pursuant to subdivision (a) or the notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder.

     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be
the fair market value of those shares as of the day before the announcement of
the proposed reorganization or shortform merger. The statement of fair market
value constitutes an offer by the shareholder to sell the shares at such price.
(Last amended by Ch. 1155, L. '80, eff. 1-1-81.)

     1302 [DISSENTING SHARES, STAMPING OR ENDORSING],--Within 30 days after the
date on which notice of the approval by the outstanding shares or the notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, the
shareholder shall submit to the corporation at its principal office or at the
office of any transfer agent thereof, (a) if the shares are certificated
securities, the shareholder's certificates representing any shares which the
shareholder demands that the corporation purchase, to be stamped or endorsed
with a statement that the shares are dissenting shares or to be exchanged for
certificates of appropriate denomination so stamped or endorsed or (b) if the
shares are uncertificated securities, written notice of the number of shares
which the shareholder demands that the corporation purchase. Upon subsequent
transfers of the dissenting shares on the books of the corporation the new
certificates, initial transaction statement, and other written statements
issued therefor shall bear a like statement, together with the name of the
original dissenting holder of the shares. (Last amended by Ch. 766, L. '86 eff.
1-1-87.)

     1303 [DISSENTING SHAREHOLDER ENTITLED TO AGREED PRICE WITH INTEREST; TIME
OF PAYMENT].--(a) If the corporation and the shareholder agree that the shares
are dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the
fair market value of any dissenting shares as between the corporation and the
holders thereof shall be filed with the secretary of the corporation.

     (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount
thereof has been agreed or within 30 days after any statutory or contractual
conditions to the reorganization are satisfied, whichever is later, and in the
case of certificated securities, subject to surrender of the certificates
thereof, unless provided otherwise by agreement. (Last amended by Ch. 766, L.
'86 eff. 1-1-87.)

     1304 [DISSENTERS ACTIONS; JOINDER; CONSOLIDATION; APPOINTMENT OF
APPRAISERS].--(a) If the corporation denies that the shares are dissenting
shares, or the corporation and the shareholder fail to agree upon the fair
market values of the shares, then the shareholder demanding purchase of such
shares as dissenting shares or any interested corporation, within six months
after the date on which notice of the approval by the outstanding shares
(Section 152) or notice pursuant to subdivision (i) of Section 1110 was mailed
to the shareholder, but not thereafter, may file a complaint in the superior
court of the proper county praying the court to determine whether the shares
are dissenting shares or the fair market value of the dissenting shares or both
or may intervene in any action pending on such a complaint.


                                      D-2
<PAGE>

     (b) Two or more dissenting shareholders may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.


     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall
first determine that issue. If the fair market value of the dissenting shares
is in issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.


     1305 [APPRAISERS DUTY AND REPORT; COURT JUDGEMENT; PAYMENT; APPEAL; COSTS
OF ACTION]--(a) If the court appoints an appraiser or appraisers, they shall
proceed forthwith to determine the fair market value per share. Within the time
fixed by the court, the appraisers, or a majority of them, shall make and file
a report in the office of the clerk of the court. Thereupon, on the motion of
any party, the report shall be submitted to the court and considered on such
evidence as the court considers relevant. If the court finds the report
reasonable, the court may confirm it.


     (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the
court, the court shall determine the fair market value of the dissenting
shares.


     (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which
any dissenting shareholder who is a party, or who has intervened, is entitled
to require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.


     (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for
the shares described in the judgment. Any party may appeal from the judgment.


     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Section 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of
Section 1301). (Last amended by Ch. 766 L. '86, eff. 1-1-87.)

     1306 [DISSENTING SHAREHOLDERS: EFFECT OF PREVENTION OF PAYMENT OF
FAIRMARKET VALUE].-- To the extent that the provisions of Chapter 5 prevent the
payment to any holders of dissenting shares of their fair market value, they
shall become creditors of the corporation for the amount thereof together with
interest at the legal rate on judgments until the date of payment, but
subordinate to all other creditors in any liquidation proceeding, such debt to
be payable when permissible under the provisions of Chapter 5.

declared and paid by the corporation upon the dissenting shares after the date
of approval of the reorganization by the outstanding shares (Section 152) and
prior to payment for the shares by the corporation shall be credited against
the total amount to be paid by the corporation therefor.

     1308 [DISSENTING SHARES, RIGHTS AND PRIVILEGES].--Except as expressly
limited in this chapter, holders of dissenting shares continue to have all the
rights and privileges incident to their shares, until the fair market value of
their shares is agreed upon or determined. A dissenting shareholder may not
withdraw a demand for payment unless the corporation consents thereto.

     1309 [DISSENTING SHARES, LOSS OF STATUS].--Dissenting shares lose their
status as dissenting shares and the holders thereof cease to be dissenting
shareholders and cease to be entitled to require the corporation to purchase
their shares upon the happening of any of the following:

     (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.


     (b) The shares are transferred prior to their submission for endorsement
in accordance with Section 1302 or are surrendered for conversion into shares
of another class in accordance with the articles.

     (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

     (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

     1310 [SUSPENSION OF CERTAIN PROCEEDINGS WHILE LITIGATION IS PENDING].--If
litigation is instituted to test the sufficiency or regularity of the votes of
the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.

     1311 [CHAPTER INAPPLICABLE TO CERTAIN CLASSES OF SHARES].--This chapter,
except Section 1312, does not apply to classes of shares whose terms and
provisions specifically set forth the amount to be paid in respect to such
shares in the event of a reorganization or merger. (Last amended by ch. 919, L.
'88, eff. 1-1-89.)

     1312 [VALIDITY OF REORGANIZATION OR SHORT FORM MERGER, ATTACK ON;
SHAREHOLDERS' RIGHTS; BURDEN OF PROOF].--(a) No shareholder of a corporation
who has a right under this chapter to demand payment of cash for the shares
held by the shareholder shall have any right at law or in equity to attack the
validity of the reorganization or short-form merger, or to have the
reorganization or short-form merger set aside or rescinded, except in an action
to test whether the number of shares required to authorize or approve the
reorganization have been legally voted in favor thereof; but any holder of
shares of a class whose terms and provisions specifically set forth the amount
to be paid in respect to them in the event of a reorganization or short-form
merger is entitled to payment in accordance with those terms and provisions or,
if the principal terms of the reorganization are approved pursuant to
subdivision (b) of Section 1202, is entitled to payment in accordance with the
terms and provisions of the approved reorganization.

     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or
short-form merger or to have the reorganization or short-form merger set aside
or rescinded, the shareholder shall not thereafter have any right to demand
payment of cash for the shareholder's shares pursuant to this chapter. The
court in any action attacking the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded shall not restrain or enjoin the consummation of the transaction
except upon 10 days, prior notice to the corporation and upon a determination
by the court that clearly no other remedy will adequately protect the
complaining shareholder or the class of shareholders of which such shareholder
is a member.

     (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attach the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled. (Last amended by Ch. 919, L.

                          CERTIFICATE OF DESIGNATIONS
                                      OF
                    SERIES 1-A CONVERTIBLE PREFERRED STOCK
                                      AND
                    SERIES 1-B CONVERTIBLE PREFERRED STOCK
                               --------------------


      Pursuant to Section 151(g) of the Delaware General Corporation Law

     The undersigned officer hereby certifies that:

     A. He is the duly elected and acting officer of Global Pharmaceutical
Corporation, a Delaware corporation (the "Corporation").

     B. On July 26, 1999, the Board of Directors of the Corporation duly
adopted resolutions in order to terminate all existing Series of Preferred
Stock with the Corporation (i.e., Series A Convertible Preferred Stock, Series
B Convertible Preferred Stock, Series C Convertible Preferred Stock and Series
D Convertible Preferred Stock) and to designate the Series 1-A Convertible
Preferred Stock and Series 1-B Convertible Preferred Stock (as set forth in the
resolution below), all upon the occurrence and simultaneously with the
Effective Time (as such term is defined in the Agreement and Plan of Merger,
dated as of July 26, 1999, by and between the Corporation and Impax
Pharmaceuticals, Inc.).

     C. The resolution contained herein has not been modified, altered or
amended and is presently in full force and effect.

     RESOLVED, that pursuant to the authority expressly vested in the Board of
Directors of the Corporation by Article 4 of the Certificate of Incorporation
of the Corporation, the Board of Directors hereby fixes and determines the
voting rights, designations, preferences, qualifications, privileges,
limitations, restrictions, options, conversion rights and other special or
relative rights of the foregoing series of the preferred stock, par value $.01
per share, which shall be designated as Series 1-A Convertible Preferred Stock
(the "Series 1-A Preferred Stock") and Series 1-B Convertible Preferred Stock
(the "Series 1-B Preferred Stock"). Except as otherwise provided herein, the
Series 1-A Preferred Stock and the Series 1-B Preferred Stock shall have
identical voting rights, designations, preferences, qualifications, privileges,
limitations, restrictions, options, conversion rights and other special or
relative rights. The designation of the Series 1-A Preferred Stock and Series
1-B Preferred Stock shall be effective upon the occurrence of and
simultaneously with the Effective Time (as such term is defined in the
Agreement and Plan of Merger, dated as of July 26, 1999, by and between the
Corporation and Impax Pharmaceuticals, Inc.), at which time the previously
designated Series A Convertible Preferred Stock, Series B Convertible Preferred
Stock, Series C Convertible Preferred Stock and Series D Convertible Preferred
Stock of the Corporation shall cease to exist and to be so designated (i.e.,
simultaneously with the Effective Time, the only designated Preferred Stock of
the Corporation shall be the Series 1-A Preferred Stock and the Series 1-B
Preferred Stock).

     1. Designation. 50,000 of shares of preferred stock, par value $.01 per
share, of the Corporation are hereby constituted as a series of the preferred
stock designated as "Series 1-A Convertible Preferred Stock." 170,000 shares of
preferred stock, par value $.01 per share, of the Corporation are hereby
constituted as a series of the preferred stock designated as "Series 1-B
Convertible Preferred Stock." The Series 1-A Preferred Stock and Series 1-B
Preferred Stock are collectively referred to herein as the "Series 1 Preferred
Stock."

     2. Dividends.

     (a) Dividends on Series 1 Preferred Stock. In the event that the
Corporation shall at any time or from time to time declare, order, pay or make
a dividend or other distribution (whether in cash, securities, rights to
purchase securities or other property) on its Common Stock, the holders of
shares of the Series 1 Preferred Stock shall be entitled to receive from the
Corporation, with respect to each share of Series 1 Preferred Stock held, a


                                      F-1
<PAGE>

dividend or distribution that is the same dividend or distribution that would
be received by a holder of the number of shares of Common Stock into which such
share of Series 1 Preferred Stock is convertible pursuant to the provisions of
Section 5 hereof on the record date for such dividend or distribution (except
in the case of the payment of a stock dividend in shares of its Common Stock if
a holder of shares of Series 1 Preferred Stock shall have given notice to the
Corporation (within five (5) business days after such holder's receipt of the
Corporation's notice regarding the stock dividend) of its election to have the
Conversion Price of its shares adjusted in accordance with Section 5(d)(i)
hereof). Any such dividend or distribution shall be declared, ordered, paid or
made on the Series 1 Preferred Stock at the same time such dividend or
distribution is declared, ordered, paid or made on the Common Stock. Dividends,
if declared, on shares of the Series 1 Preferred Stock shall accrue and be
cumulative from the payment date of such dividend on such shares.

     (b) Limitation on Dividends, Repurchases and Redemptions. So long as any
shares of Series 1 Preferred Stock shall be outstanding, the Corporation shall
not declare or pay or set apart for payment any dividends or make any other
distributions on any Junior Securities, whether in cash, securities, rights to
purchase securities or other property (other than dividends or distributions
payable in shares of the class or series upon which such dividends or
distributions are declared or paid), nor shall the Corporation purchase, redeem
or otherwise acquire for any consideration or make payment on account of the
purchase, redemption or other retirement of any Parity Securities or Junior
Securities, nor shall any monies be paid or made available for a sinking fund
for the purchase or redemption of any Parity Securities or Junior Securities,
unless with respect to all of the foregoing all dividends or other
distributions to which the holders of Series 1 Preferred Stock shall have been
entitled, pursuant to Section 2(a) hereof, shall have been paid or declared and
a sum of money has been set apart for the full payment thereof.

     (c) Pro Rata Payments. In the event that full dividends are not paid or
made available to the holders of all outstanding shares of Series 1 Preferred
Stock and of any Parity Securities and funds available for payment of dividends
shall be insufficient to permit payment in full to holders of all such stock of
the full preferential amounts to which they are then entitled, then the entire
amount available for payment of dividends shall be distributed ratably among
all such holders of Series 1 Preferred Stock and of any Parity Securities in
proportion to the full amount to which they would otherwise be respectively
entitled.

     3. Preference on Liquidation.

     (a) Liquidation Preference for Series 1 Preferred Stock. In the event that
the Corporation shall liquidate, dissolve or wind up, whether voluntarily or
involuntarily, no distribution shall be made to the holders of shares of Common
Stock or other Junior Securities (and no monies shall be set apart for such
purpose) unless prior thereto, the holders of shares of Series 1 Preferred
Stock shall have received an amount per share equal to the greater of (i) the
sum of (x) the Liquidation Value, plus (y) all declared but unpaid dividends
thereon through the date of distribution, (ii) ratable distributions determined
with respect to the holders of Series 1 Preferred Stock and Common Stock on the
basis of the number of shares of Common Stock into which such Series 1
Preferred Stock could be converted pursuant to the provisions of Section 5
hereof immediately prior to such distribution and (iii) the Payment Amount, on
a per share basis (the greater of (i), (ii) and (iii) above is herein referred
to as the "Series 1 Liquidation Preference"). The "Liquidation Value" means
$100 per share with respect to the Series 1 Preferred Stock.

     (b) Pro Rata Payments. If, upon any such liquidation, dissolution or other
winding up of the affairs of the Corporation, the assets of the Corporation
shall be insufficient to permit the payment in full of the Series 1 Liquidation
Preference for each share of Series 1 Preferred Stock then outstanding and the
full liquidating payments on all Parity Securities, then the assets of the
Corporation remaining shall be ratably distributed among the holders of Series
1 Preferred Stock and of any Parity Securities in proportion to the full
amounts to which they would otherwise be respectively entitled if all amounts
thereon were paid in full.

     (c) Sale Not a Liquidation. Neither the voluntary sale, conveyance,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the
Corporation nor the consolidation, merger or other business combination of the
Corporation with or into one or more corporations shall be deemed to be a
liquidation, dissolution or winding-up, voluntary or involuntary, of the
Corporation.


                                      F-2
<PAGE>

     (d) Notice of Liquidation. Written notice of any liquidation, dissolution
or winding up of the Corporation, stating the payment date or dates when and
the place or places where amounts distributable in such circumstances shall be
payable, shall be given by first class mail, postage prepaid, not less than
thirty (30) days prior to any payment date specified therein, to the holders of
record of the Series 1 Preferred Stock at their respective addresses as shall
appear on the records of the Corporation.


     4. Voting.


     (a) General. In addition to any voting rights provided in the
Corporation's Certificate of Incorporation or by law, the Series 1-A Preferred
Stock and the Series 1-B Preferred Stock shall vote together with the Common
Stock as a single class on all actions to be voted on by the stockholders of
the Corporation. Each share of Series 1 Preferred Stock shall entitle the
holder thereof to such number of votes per share on each such action as shall
equal the number of shares of Common Stock into which each share of Series 1
Preferred Stock is then convertible. The holders of Series 1 Preferred Stock
shall be entitled to notice of any stockholder's meeting in accordance with the
By-Laws of the Corporation.


     (b) Board of Directors. The Corporation shall not, without the written
consent or affirmative vote of the holders representing at least 80% of the
shares of Series 1 Preferred Stock then outstanding, given in writing or by
vote at a meeting, consenting or voting (as the case may be) separately as a
class, increase the maximum number of directors constituting the Board of
Directors to a number in excess of ten (10).


     (c) Election of Directors. So long as either (i) a Director Holder owns at
least 40%, on an aggregate basis, of the shares of Series 1 Preferred Stock
owned or acquired, as the case may be, by such holder at the Effective Time
(the "Minimum Election Holdings") or (ii) any Transferee owns shares of Series
1 Preferred Stock at least equal to the Minimum Election Holdings of such
transferor holder, and the Corporation consented to such Transferee (which
consent shall not be unreasonably withheld), each such Director Holder or
Transferee, as the case may be, shall be entitled, but not required, to elect
one (1) director of the Corporation; provided, however, in no event shall any
Director Holder and such Director Holder's Transferee or Transferees be
entitled to elect, in the aggregate, more than one (1) director of the
Corporation pursuant to the provisions of this Section 4(c). A director or the
directors elected are referred to as a "Preferred Director" or the "Preferred
Directors."


     Any Preferred Director may be removed with or without cause by, and shall
not be removed except by, the Director Holder or Transferee who elected such
director. A vacancy in the directorship to be held by a Preferred Director
shall be filled only by the Director Holder or Transferee who elected such
director, so long as such Director Holder or Transferee, as the case may be,
continues to then hold shares of Series 1 Preferred Stock at lest equal to the
Minimum Election Holdings.


     5. Conversion. The holders of shares of Series 1 Preferred Stock shall
have the right to convert all or a portion of such shares into fully paid and
nonassessable shares of Common Stock or any capital stock or other securities
into which such Common Stock shall have been changed or any capital stock or
other securities resulting from a reclassification thereof as follows:


     (a) Right to Convert. Subject to and upon compliance with the provisions
of this Section 5, a holder of shares of Series 1 Preferred Stock shall have
the right, at the option of such holder, at any time, to convert any or all of
such shares into the number of fully paid and nonassessable shares of Common
Stock (calculated as to each conversion rounded down to the nearest 1/100th of
a share) obtained by dividing the aggregate Liquidation Value of the shares to
be converted, plus all declared but unpaid dividends thereon through the date
of conversion (unless the holder of shares of Series 1 Preferred Stock being so
converted shall have elected to receive any such dividends in respect of the
shares being converted subsequent to conversion), by the Conversion Price and
by surrender of such shares, such surrender to be made in the manner provided
in paragraph (b) of this Section 5. The Common Stock issuable upon conversion
of the shares of Series 1 Preferred Stock, when such Common Stock shall be
issued in accordance with the terms hereof, are hereby declared to be and shall
be duly authorized, validly issued, fully paid and nonassessable Common Stock
held by the holders thereof.


     (b) Mechanics of Conversion. Each holder of Series 1 Preferred Stock that
desires to convert the same into shares of Common Stock shall surrender the
certificate or certificates therefor, duly endorsed, at the principal


                                      F-3
<PAGE>

office of the Corporation or of any transfer agent for the Series 1 Preferred
Stock or Common Stock, accompanied by written notice to the Corporation that
such holder elects to convert the same and stating therein the number of shares
of Series 1 Preferred Stock being converted and whether all declared and unpaid
dividends in respect of such shares shall be included in the calculation set
forth in Section 5(a) hereof, and setting forth the name or names in which such
holder wishes the certificate or certificates for shares of Common Stock to be
issued if such name or names shall be different than that of such holder.
Thereupon, the Corporation shall issue and deliver at such office on not later
than the fifth Business Day thereafter (unless such conversion is in connection
with an underwritten public offering of Common Stock, in which event
concurrently with such conversion) to such holder or on such holder's written
order, (i) a certificate or certificates for the number of validly issued,
fully paid and nonassessable full shares of Common Stock to which such holder
is entitled and (ii) if less than the full number of shares of Series 1
Preferred Stock evidenced by the surrendered certificate or certificates are
being converted, a new certificate or certificates, of like tenor, for the
number of shares evidenced by such surrendered certificate or certificates less
the number of shares converted.

     Each conversion shall be deemed to have been effected immediately prior to
the close of business on the date of such surrender of the shares to be
converted (except that if such conversion is in connection with an underwritten
public offering of Common Stock, then such conversion shall be deemed to have
been effected upon such surrender) so that the rights of the holder thereof as
to the shares being converted shall cease at such time except for the right to
receive shares of Common Stock and if the holder of the shares being so
converted shall have elected to receive dividends subsequent to such
conversion, all accrued and unpaid dividends in accordance herewith, and the
person entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder of such
shares of Common Stock at such time.

     (c) Conditional Conversion. Notwithstanding any other provision hereof, if
conversion of any shares of Series 1 Preferred Stock is to be made in
connection with a public offering of Common Stock or any transaction described
in Section 5(d)(vii) hereof, the conversion of any shares of Series 1 Preferred
Stock may, at the election of the holder thereof, be conditioned upon the
consummation of the public offering or such transaction, in which case such
conversion shall not be deemed to be effective until the consummation of such
public offering or transaction.

     (d) Adjustment of the Conversion Price. The Conversion Price shall be
adjusted from time to time as follows (except that from the date hereof the
Corporation may issue securities for a consideration per share above or below
the Conversion Price, in the form of Convertible Securities, Common Stock,
warrants or rights to purchase Common Stock or Convertible Securities, with an
aggregate Market Value up to $10 million before any adjustments to the
Conversion Price shall be made pursuant to this Section 5(d); provided that
such $10 million threshold may be achieved through one such issuance or a
cumulation of several such issuances); and provided further for purposes of
computing such $10 million threshold, the value of any securities referred to
in subsections (a) or (b) of the definition of Additional Shares of Stock in
Section 10 hereof, shall be excluded.

       (i) Adjustment for Stock Splits and Combinations. If the Corporation at
   any time or from time to time after the Issue Date, pays a stock dividend
   in shares of its Common Stock, issues any convertible debt securities,
   effects a subdivision of the outstanding Common Stock, combines the
   outstanding shares of Common Stock, issues by reclassification of shares of
   its Common Stock any shares of capital stock of the Corporation, makes a
   distribution of any of its assets (other than cash dividends payable out of
   earnings or retained earnings in the ordinary course of business) then, in
   each such case, the Conversion Price in effect immediately prior to such
   event shall be adjusted so that each holder of shares of Series 1 Preferred
   Stock shall have the right to convert its shares of Series 1 Preferred
   Stock into the number of shares of Common Stock which it would have owned
   after the event had such shares of Series 1 Preferred Stock been converted
   immediately before the happening of such event. Any adjustment under this
   Section 5(d)(i) shall become effective retroactively immediately after the
   record date in the case of a dividend and distribution and shall become
   effective immediately after the effective date in the case of a issuance,
   subdivision, combination or reclassification. If the Corporation pays a
   stock dividend in shares of its Common Stock and the holders of the Series
   1 Preferred Stock received such stock dividend pursuant to Section 2(a)
   hereof, the Conversion Price shall not be adjusted for such stock dividend
   under this Section 5(d)(i).

       (ii) Issuance of Additional Shares of Stock. If the Corporation shall
   (except as hereinbefore or hereinafter provided) issue or sell Additional
   Shares of Stock in exchange for consideration in an amount per


                                      F-4
<PAGE>

   Additional Share of Stock less than the Conversion Price in effect
   immediately prior to such issuance or sale of Additional Shares of Stock,
   then the Conversion Price as to the Common Stock into which the Series 1
   Preferred Stock is convertible immediately prior to such adjustment shall
   be adjusted to equal the price determined by multiplying the applicable
   Conversion Price for such Series 1-A Preferred Stock or Series 1-B
   Preferred Stock, as the case may be, by a fraction, of which:

          (x) the numerator shall be (1) the number of shares of Common Stock
       outstanding immediately prior to such issuance or sale of Additional
       Shares of Stock plus (2) the number of shares of Common Stock which the
       aggregate amount of consideration, if any, received by the Corporation
       for the total number of such Additional Shares of Stock so issued or
       sold would purchase at the greater of (I) the Market Price per share of
       the Common Stock in effect immediately prior to such issuance or sale of
       Additional Shares of Stock or (II) the Conversion Price in effect
       immediately prior to such issuance or sale of Additional Shares of
       Stock, and

          (y) the denominator shall be the number of shares of Common Stock
       outstanding immediately after such issuance or sale of Additional Shares
       of Stock; provided, however, that such adjustment shall be made only if
       the Conversion Price determined from such adjustment shall be less than
       the Conversion Price in effect immediately prior to the issuance of such
       Additional Shares of Stock.

   The provisions of this Section 5(d)(ii) shall not apply to any issuance of
   Additional Shares of Common Stock for which an adjustment is provided under
   Section 5(d)(i) or which are dividends or distributions received by the
   holders of the Series 1 Preferred Stock pursuant to Section 2(a) hereof.

       (iii) (A) Issuance of Warrants or Other Rights. If at any time (i) the
   Corporation shall in any manner (whether directly or by assumption in a
   merger in which the Corporation is the surviving corporation) issue or sell
   any warrants or other rights to subscribe for or purchase any Additional
   Shares of Stock or any Convertible Securities, whether or not the rights to
   exchange or convert thereunder are immediately exercisable, and the
   consideration (computed in accordance with Section 5(d)(vi)(A) hereof)
   received for such warrants or other rights or such Convertible Securities
   shall be less than the Conversion Price in effect immediately prior to the
   time of such issue or sale, then the Conversion Price shall be adjusted as
   provided in Section 5(d)(ii). No further adjustments of the Conversion
   Price shall be made upon the actual issue of such Common Stock or of such
   Convertible Securities upon exercise of such warrants or other rights or
   upon the actual issue of such Common Stock upon such conversion or exchange
   of such Convertible Securities.

       (B) Issuance of Convertible Securities. If at any time the Corporation
   shall in any manner (whether directly or by assumption in a merger in which
   the Corporation is the surviving corporation) issue or sell, any
   Convertible Securities, whether or not the rights to convert thereunder are
   immediately exercisable, and the consideration (computed in accordance with
   Section 5(d)(vi)(A) hereof) received for such Convertible Securities shall
   be less than the Conversion Price in effect immediately prior to the time
   of such issue or sale, then the Conversion Price shall be adjusted as
   provided in Section 5(d)(ii). No adjustment of the Conversion Price shall
   be made under this Section 5(d)(iii)(B) upon the issuance of any
   Convertible Securities which are issued pursuant to the exercise of any
   warrants or other subscription or purchase rights therefor, if any such
   adjustment shall previously have been made upon the issuance of such
   warrants or other rights pursuant to Section 5(d)(iii)(A). No further
   adjustments of the Conversion Price shall be made upon the actual issue of
   such Common Stock upon conversion of such Convertible Securities and, if
   any issue or sale of such Convertible Securities is made upon exercise of
   any warrant or other right to subscribe for or to purchase any such
   Convertible Securities for which adjustments of the Conversion Price have
   been or are to be made pursuant to other provisions of this Section 5(d),
   no further adjustments of the Conversion Price shall be made by reason of
   such issue or sale.

       (iv) Superseding Adjustments. If, at any time after any adjustment of
   the Conversion Price at which the Series 1 Preferred Stock is convertible
   shall have been made pursuant to Section 5(d)(iii) as a result of any
   issuance of warrants, rights or Convertible Securities,

          (A) such warrants or rights, or the right of conversion or exchange
       in such other Convertible Securities, shall expire, and all or a portion
       of such warrants or rights, or the right of conversion or exchange with
       respect to all or a portion of such other Convertible Securities, as the
       case may be, shall not have been exercised, or


                                      F-5
<PAGE>

          (B) the consideration per share for which shares of Stock are
       issuable pursuant to such warrants or rights, or the terms of such other
       Convertible Securities, shall be increased solely by virtue of
       provisions therein contained for an automatic increase in such
       consideration per share upon the occurrence of a specified date or
       event,

   then such previous adjustment shall be rescinded and annulled and the
   Additional Shares of Stock which were deemed to have been issued by virtue
   of the computation made in connection with the adjustment so rescinded and
   annulled shall no longer be deemed to have been issued by virtue of such
   computation. Thereupon, a recomputation shall be made of the effect of such
   rights or options or other Convertible Securities on the basis of

          (C) treating the number of Additional Shares of Stock or other
       property, if any, theretofore actually issued or issuable pursuant to
       the previous exercise of any such warrants or rights or any such right
       of conversion or exchange, as having been issued on the date or dates of
       any such exercise and for the consideration actually received and
       receivable therefor, and

          (D) treating any such warrants or rights or any such other
       Convertible Securities which then remain outstanding as having been
       granted or issued immediately after the time of such increase of the
       consideration per share for which shares of Stock or other property are
       issuable under such warrants or rights or other Convertible Securities;

   whereupon a new adjustment of the Conversion Price at which the Series 1
   Preferred Stock is convertible shall be made, which new adjustment shall
   supersede the previous adjustment so rescinded and annulled.

       (v) Antidilution Adjustments Under Other Securities. Without limiting
   any other rights available hereunder to the holders of the Series 1
   Preferred Stock, if there is an antidilution adjustment (i) under any
   Convertible Securities other than the Series 1 Preferred Stock, whether
   issued prior to or after the Issue Date, or (ii) under any rights, options
   or warrants to purchase Additional Shares of Stock, whether issued prior to
   or after the Issue Date which, in either case, results in a reduction in
   the exercise or purchase price with respect to such security or rights or
   results in an increase in the number of Additional Shares of Stock
   obtainable under such Convertible Security, right, option or warrant, then
   an adjustment shall be made to the Conversion Price hereunder. Any such
   adjustment pursuant to this Section 5(d)(v) shall be whichever of the
   following results in a lower Conversion Price: (A) a reduction in the
   Conversion Price equal to the percentage reduction in such exercise or
   purchase price with respect to such Convertible Security, right, option or
   warrant or (B) a reduction in the Conversion Price which will result in the
   same percentage increase in the number of shares of Common Stock available
   hereunder as the percentage increase in the number of Additional Shares of
   Stock available under such Convertible Security, right, option or warrant.
   Any such adjustment under this Section 5(d)(v) shall only be made if it
   would result in a lower Conversion Price than that which would be
   determined pursuant to any other antidilution adjustment otherwise required
   hereunder as a result of the event or circumstance which triggered the
   adjustment to such Convertible Security, right, option or warrant, and if
   an adjustment is made pursuant to this Section 5(d)(v), such other
   antidilution adjustment otherwise required hereunder shall not be made as a
   result of such event or circumstance.

       (vi) Other Provisions Applicable to Adjustments under this Section. The
   following provisions shall be applicable to making adjustments to the
   shares of Common Stock into which the Series 1 Preferred Stock is
   convertible and the Conversion Price at which the Series 1 Preferred Stock
   is convertible provided for in this Section 5(d):

          (A) Computation of Consideration. To the extent that any Additional
       Shares of Stock or any Convertible Securities or any warrants or other
       rights to subscribe for or purchase any Additional Shares of Stock or
       any Convertible Securities shall be issued for cash consideration, the
       consideration received by the Corporation therefor shall be the amount
       of the cash received by the Corporation therefor, or, if such Additional
       Shares of Stock or Convertible Securities are offered by the Corporation
       for subscription, the subscription price, or, if such Additional Shares
       of Stock or Convertible Securities are sold to underwriters or dealers
       for public offering without a subscription offering, the initial public
       offering price (subtracting (i) in any case, any amounts paid or
       receivable for accrued interest or accrued dividends, (ii) in the case
       of any public offering, any compensation, discounts or


                                      F-6
<PAGE>

       expenses paid or incurred by the Corporation for and in the underwriting
       of, or otherwise in connection with, the issuance thereof, and (iii) in
       the case of any transaction other than a public offering, any
       compensation, discounts or expenses paid or incurred by the Corporation
       for and in the underwriting of, or otherwise in connection with, the
       issuance thereof; provided that, in the case of clause (iii), such
       amount is in excess of eight percent (8%) of the aggregate costs of such
       transactions, and then only to the extent of such excess). To the extent
       that such issuance shall be for a consideration other than cash, then
       except as herein otherwise expressly provided, the amount of such
       consideration shall be deemed to be the fair value of such consideration
       at the time of such issuance as determined in good faith by the Board of
       Directors of the Corporation. In case any Additional Shares of Stock or
       any Convertible Securities or any warrants or other rights to subscribe
       for or purchase such Additional Shares of Stock or Convertible
       Securities shall be issued in connection with any merger in which the
       Corporation issues any securities, the amount of consideration therefor
       shall be deemed to be the fair value, as determined in good faith by the
       Board of Directors of the Corporation, of such portion of the assets and
       business of the nonsurviving corporation as such Board in good faith
       shall determine to be attributable to such Additional Shares of Stock,
       Convertible Securities, warrants or other rights, as the case may be.
       The consideration for any Additional Shares of Stock issuable pursuant
       to any warrants or other rights to subscribe for or purchase the same
       shall be the consideration received by the Corporation for issuing such
       warrants or other rights plus the additional consideration payable to
       the Corporation upon exercise of such warrants or other rights. The
       consideration for any Additional Shares of Stock issuable pursuant to
       the terms of any Convertible Securities shall be the consideration
       received by the Corporation for issuing warrants or other rights to
       subscribe for or purchase such Convertible Securities, plus the
       consideration paid or payable to the Corporation in respect of the
       subscription for or purchase of such Convertible Securities, plus the
       additional consideration, if any, payable to the Corporation upon the
       exercise of the right of conversion or exchange in such Convertible
       Securities. In case of the issuance at any time of any Additional Shares
       of Stock or Convertible Securities in payment or satisfaction of any
       dividends upon any class of stock other than Common Stock, the
       Corporation shall be deemed to have received for such Additional Shares
       of Stock or Convertible Securities a consideration equal to the amount
       of such dividend so paid or satisfied.


          (B) When Adjustments to Be Made. The adjustments required by this
       Section 5(d) shall be made whenever and as often as any event requiring
       an adjustment shall occur, except that any adjustment of the Conversion
       Price that would otherwise be required may be postponed (except in the
       case of a subdivision or combination of shares of the Common Stock, as
       provided for in Section 5(d)(i)) up to, but not beyond the date of
       exercise if such adjustment either by itself or with other adjustments
       not previously made amount to a change in the Conversion Price of less
       than $.05. Any adjustment representing a change of less than such
       minimum amount (except as aforesaid) which is postponed shall be carried
       forward and made as soon as such adjustment, together with other
       adjustments required by this Section 5(d) and not previously made, would
       result in a minimum adjustment or on the date of conversion. For the
       purpose of any adjustment, any event shall be deemed to have occurred at
       the close of business on the date of its occurrence.


          (C) Fractional Interests. In computing adjustments under this Section
       5(d), fractional interests in the Common Stock shall be taken into
       account to the nearest 1/100th of a share.


          (D) Challenge to Good Faith Determination. Whenever the Board of
       Directors of the Corporation shall be required to make a determination
       in good faith of the fair value of any item under this Section 5(d),
       such determination may be challenged in good faith by a holder of Series
       1 Preferred Stock and any dispute shall be resolved by an investment
       banking firm of recognized national standing jointly selected by the
       Corporation and such holder. The fees of such investment banker shall be
       borne by such holder if the Corporation's calculation is determined to
       be between 95% and 105% of the calculation of such banker.


       (vii) Reorganization, Reclassification, Merger or Consolidation. If the
   Corporation shall at any time reorganize or reclassify the outstanding
   shares of Common Stock (other than a change in par value, or from no par
   value to par value, or from par value to no par value, or as a result of a
   subdivision or combination)


                                      F-7
<PAGE>

   or consolidate with or merge into another corporation (where the
   Corporation is not the continuing corporation after such merger or
   consolidation), the holders of Series 1 Preferred Stock shall thereafter be
   entitled to receive upon conversion of the Series 1 Preferred Stock in
   whole or in part, the same kind and number of shares of stock and other
   securities, cash or other property (and upon the same terms and with the
   same rights) as would have been distributed to a holder upon such
   reorganization, reclassification, consolidation or merger had such holder
   converted its Series 1 Preferred Stock immediately prior to such
   reorganization, reclassification, consolidation or merger (subject to
   subsequent adjustments under Section 5(d) hereof). The Conversion Price
   upon such conversion shall be the Conversion Price that would otherwise be
   in effect pursuant to the terms hereof. Notwithstanding anything herein to
   the contrary, the Corporation will not effect any such reorganization,
   reclassification, merger or consolidation unless prior to the consummation
   thereof, the corporation which may be required to deliver any stock,
   securities or other assets upon the conversion of the Series 1 Preferred
   Stock shall agree by an instrument in writing to deliver such stock, cash,
   securities or other assets to the holders of the Series 1 Preferred Stock.
   A sale, transfer or lease of all or substantially all of the assets of the
   Corporation to another person shall be deemed a reorganization,
   reclassification, consolidation or merger for the foregoing purposes.

       (viii) Exceptions to Adjustment of Conversion Price. Anything herein to
   the contrary notwithstanding, the Corporation shall not make any adjustment
   of the Conversion Price in the case of the issuance of shares of Common
   Stock to holders of the Series 1 Preferred Stock upon conversion of all or
   any portion of their shares of Series 1 Preferred Stock.

       (ix) Chief Financial Officer's Opinion. Upon each adjustment of the
   Conversion Price, and in the event of any change in the rights of a holder
   of Series 1 Preferred Stock by reason of other events herein set forth,
   then and in each such case, the Corporation will promptly obtain a
   certificate of the chief financial officer of the Corporation, stating the
   adjusted Conversion Price, or specifying the other shares of the Common
   Stock, securities or assets and the amount thereof receivable as a result
   of such change in rights, and setting forth in reasonable detail the method
   of calculation and the facts upon which such calculation is based. The
   Corporation will promptly mail a copy of such certificate to the holders of
   Series 1 Preferred Stock. If a holder disagrees with such calculation, the
   Corporation agrees to obtain within thirty (30) business days an opinion of
   a firm of independent certified public accountants selected by the
   Corporation's Board of Directors and acceptable to such holder to review
   such calculation and the opinion of such firm of independent certified
   public accountants shall be final and binding on the parties and shall be
   conclusive evidence of the correctness of the computation with respect to
   any such adjustment of the Conversion Price.

       (x) Corporation to Prevent Dilution. In case at any time or from time to
   time conditions arise by reason of action taken by the Corporation, which
   in the good faith opinion of its Board of Directors or a majority of the
   holders of the Series 1 Preferred Stock are not adequately covered by the
   provisions of this Section 5(d), and which might materially and adversely
   affect the exercise rights of the holders of the Series 1 Preferred Stock,
   the Board of Directors of the Corporation shall appoint such firm of
   independent certified public accountants acceptable to a majority of the
   holders of the Series 1 Preferred Stock, which shall give their opinion
   upon the adjustment, if any, on a basis consistent with the standards
   established in the other provisions of this Section 5(d), necessary with
   respect to the Conversion Price, so as to preserve, without dilution (other
   than as specifically contemplated by the Certificate of Incorporation), the
   exercise rights of the holders of the Series 1 Preferred Stock. Upon
   receipt of such opinion, the Board of Directors of the Corporation shall
   forthwith make the adjustments described therein.

   (e) No Impairment. The Corporation will not, by amendment of its Certificate
of Incorporation or through any reorganization, recapitalization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the Corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of Section 5 hereof and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the holders of the
Series 1 Preferred Stock against impairment.

   (f) No Fractional Shares Adjustments. No fractional shares shall be issued
upon conversion of the Series 1 Preferred Stock. If more than one share of the
Series 1 Preferred Stock is to be converted at one time by the


                                      F-8
<PAGE>

same stockholder, the number of full shares issuable upon such conversion shall
be computed on the basis of the aggregate amount of the shares to be converted.
Instead of any fractional shares of Common Stock which would otherwise be
issuable upon conversion of any shares of Series 1 Preferred Stock, the
Corporation will pay a cash adjustment in respect of such fractional interest
in an amount equal to the same fraction of the Market Price per share of Common
Stock at the close of business on the day of conversion which such fractional
share of Series 1 Preferred Stock would be convertible into on such date.

     (g) Shares to be Reserved. The Corporation shall at all times reserve and
keep available, out of its authorized and unissued stock, solely for the
purpose of effecting the conversion of the Series 1 Preferred Stock, such
number of shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all of the Series 1 Preferred Stock from time to time
outstanding. The Corporation shall from time to time, in accordance with the
laws of the State of Delaware, increase the authorized number of shares of
Common Stock if at any time the number of shares of authorized but unissued
Common Stock shall be insufficient to permit the conversion in full of the
Series 1 Preferred Stock.

     (h) Taxes and Charges. The Corporation will pay any and all issue or other
taxes that may be payable in respect of any issuance or delivery of shares of
Common Stock on conversion of the Series 1 Preferred Stock. The Corporation
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issuance or delivery of Common Stock in a name
other than that of the Series 1 Preferred Stock, and no such issuance or
delivery shall be made unless and until the Person requesting such issuance has
paid to the Corporation the amount of such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.


     (i) Accrued Dividends. Upon conversion of any shares of Series 1 Preferred
Stock, the holder thereof shall be entitled to receive any accrued but unpaid
dividends in respect of the shares of Series 1 Preferred Stock so converted to
the date of such conversion.


     (j) Closing of Books. The Corporation will at no time close its transfer
books against the transfer of any shares of Series 1 Preferred Stock or of any
shares of Common Stock issued or issuable upon the conversion of any shares of
Series 1 Preferred Stock in any manner which interferes with the timely
conversion of such shares of Series 1 Preferred Stock.


     6. Redemption


     (a) Redemption Price. Any redemption of the Series 1 Preferred Stock
pursuant to Section 6(b) shall be at a price per share equal to the Liquidation
Value plus all declared but unpaid dividends thereon through the redemption
date (the "Mandatory Redemption Price"). Any redemption of the Series 1
Preferred Stock pursuant to Section 6(d) shall be at a price per share equal to
the Series 1 Liquidation Preference, except that, for purposes of calculation
of the redemption price under this Section 6(a), clause (ii) of the definition
of Series 1 Liquidation Preference in Section 3(a) hereof shall provide for the
amount per share such holders would have received if such holders had converted
their shares of Series 1 Preferred Stock into shares of Common Stock
immediately prior to the Fundamental Change (the "Optional Redemption Price").
The Mandatory Redemption Price shall be paid, at the election of the
Corporation, in cash or shares of Common Stock which have been registered under
a registration statement under the Securities Act of 1933, as amended, which
registration statement is effective, provided, that, for purposes of
calculating the number of shares of Common Stock to be received by each holder
of Series 1 Preferred Stock, each such share of Common Stock shall be valued at
10% less than the Market Price.


     (b) Mandatory Redemption. Subject to Section 6(a) hereof, the Corporation
shall redeem all of the then outstanding shares of Series 1 Preferred Stock at
the Mandatory Redemption Price on March 31, 2004.


     (c) Procedures for Redemption. In the event the Corporation shall redeem
shares of Series 1 Preferred Stock pursuant to Section 6(b), the Corporation
shall give written notice of such redemption by first class mail, postage
prepaid, mailed not less than thirty (30) nor more than ninety (90) days prior
to the redemption date, to each holder of record of the shares to be redeemed,
at such holder's address as the same appears on the stock records of the
Corporation. Each such notice shall state: (i) the redemption date; (ii) the
number of shares of Series 1 Preferred Stock to be redeemed; (iii) the
Mandatory Redemption Price or Optional Redemption Price, as the case


                                      F-9
<PAGE>

may be; (iv) the place or places where certificates for such shares are to be
surrendered for payment of the Mandatory Redemption Price or Optional
Redemption Price, as the case may be; (v) that payment will be made upon
presentation and surrender of such Series 1 Preferred Stock; (vi) the then
current Conversion Price and the date on which the right to convert such shares
of Series 1 Preferred Stock will expire; (vii) that dividends on the shares to
be redeemed shall cease to accrue following such redemption date; (viii) that
such redemption is mandatory, if pursuant to Section 6(b) and (ix) that
dividends, if any, accrued to and including the date fixed for redemption will
be paid as specified in such notice. Notice having been mailed as aforesaid,
from and after the redemption date, unless the Corporation shall be in default
in the payment of the Mandatory Redemption Price or Optional Redemption Price,
as the case may be (including any accrued and unpaid dividends to (and
including) the date fixed for redemption), (A) dividends on the shares of the
Series 1 Preferred Stock so called for redemption shall cease to accrue, (B)
such shares shall be deemed no longer outstanding and (C) all rights of the
holders thereof as stockholders of the Corporation (except the right to receive
from the Corporation (i) any moneys payable upon redemption without interest
thereon and (ii) any shares of Series 1 Preferred Stock and Common Stock
pursuant to Section 6(a) hereof) shall cease.

     Upon surrender in accordance with such notice of the certificates for any
such shares so redeemed (properly endorsed or assigned for transfer, if the
Board of Directors shall so require and the notice shall so state), such shares
shall be redeemed by the Corporation at the applicable Mandatory Redemption
Price.

     Notwithstanding the foregoing, if notice of redemption has been given
pursuant to this Section 6 and any holder of shares of Series 1 Preferred Stock
shall, prior to the close of business on the third (3rd) Business Day preceding
the redemption date, give written notice to the Corporation pursuant to Section
5(b) hereof of the conversion of any or all of the shares to be redeemed held
by such holder (accompanied by a certificate or certificates for such shares,
duly endorsed or assigned to the Corporation), then the conversion of such
shares to be redeemed shall become effective as provided in Section 5 hereof.


     (d) Redemption at Option of Holder Upon a Fundamental Change. Subject to
Section 6(a) hereof, if a Fundamental Change occurs, each holder of Series 1
Preferred Stock shall have the right, at the holder's option, to require the
Corporation to repurchase all of such holder's Series 1 Preferred Stock, or any
portion thereof, on the date (the "Repurchase Date") selected by the
Corporation that is not less than ten (10) nor more than twenty (20) days after
the Final Surrender Date, at a price per share equal to the Optional Redemption
Price. The Corporation agrees that it will not complete any Fundamental Change
unless proper provision has been made to satisfy its obligations under this
Section 6(d).


     (e) Notice of Fundamental Change. Within thirty (30) days after the
occurrence of a Fundamental Change, the Corporation shall mail to all holders
of record of the Series 1 Preferred Stock a notice in the manner and containing
the information set out in Section 6(c), except that, for purposes of this
Section 6(e), such notice shall also describe the occurrence of such
Fundamental Change and of the repurchase right arising as a result thereof. To
exercise the repurchase right, a holder of Series 1 Preferred Stock must
surrender, on or before the date which is, subject to any contrary requirements
of applicable law, thirty (30) days after the date of mailing of the notice
from the Corporation (the "Final Surrender Date"), the certificates
representing the Series 1 Preferred Stock with respect to which the right is
being exercised, duly endorsed for transfer to the Corporation, together with a
written notice of election.


     (f) Election Irrevocable. An election by a holder of Series 1 Preferred
Stock to have the Corporation repurchase shares of Series 1 Preferred Stock
pursuant to Section 6(d) shall become irrevocable at the close of business on
the relevant Repurchase Date.


     7. Shares to be Retired. Any share of Series 1 Preferred Stock converted,
redeemed, repurchased or otherwise acquired by the Corporation shall be retired
and cancelled and shall upon cancellation be restored to the status of
authorized but unissued shares of preferred stock, subject to reissuance by the
Board of Directors as shares of preferred stock of one or more other series but
not as shares of Series 1 Preferred Stock.


     8. Preemptive Rights.


     (a) Except (i) for issuances of pro rata dividends to all holders of
Common Stock, (ii) stock issued to employees, officers or directors in
connection with management options or incentive plans approved by the


                                      F-10
<PAGE>

Board of Directors, (iii) stock issued in connection with any merger,
acquisition or business combination, (iv) stock issued for consideration
amounting to less than $500,000 in any single transaction where the purchase
price is not less than the then applicable Conversion Price, provided that the
aggregate amount of all such transactions shall not exceed $1,000,000 or (v)
stock issued in connection with any joint venture, partnership or limited
liability company, or other entities with which the Corporation has a business
relationship, the holders of the Series 1 Preferred Stock, in order to enable
such holders to maintain their fully diluted percentage ownership of the
Corporation, shall have preemptive rights, as hereinafter set forth, to
purchase any capital stock, including any warrants or securities convertible
into capital stock, of the Corporation hereafter issued by the Corporation so
that a holder of the Series 1 Preferred Stock shall hereafter be entitled to
acquire a percentage of capital stock which is hereafter issued equal to the
same percentage of the issued and outstanding Common Stock of the Corporation
as is held (directly or obtainable upon conversion of the Series 1 Preferred
Stock) by such holder of Series 1 Preferred Stock immediately prior to the date
on which the capital stock is to be issued on a fully diluted basis. As used
herein, "issue" (and variations thereof) includes sales and transfers by the
Corporation of treasury shares. From the date hereof until the fifth
anniversary hereof, the total number of shares issuable under clause (v) of
this Section 8(a) shall not exceed 300,000.

     (b) The Corporation shall, before issuing any additional capital stock
(other than the exceptions referred to in Section 8(a) hereof), give written
notice thereof to the holders of the Series 1 Preferred Stock. Such notice
shall specify what type of instrument the Corporation intends to issue and the
consideration which the Corporation intends to receive therefor. For a period
of twenty (20) days following receipt by the holders of the Series 1 Preferred
Stock of such notice, the Corporation shall be deemed to have irrevocably
offered to sell to the holders of the Series 1 Preferred Stock a sufficient
number of shares of such capital stock so that the holders of the Series 1
Preferred Stock, if such holders elects to acquire such shares as hereinafter
set forth, shall be capable of acquiring the same percentage of such shares as
the percentage of Common Stock beneficially owned (directly or obtainable upon
conversion of the Series 1 Preferred Stock) by such holders immediately prior
to the proposed issuance on a fully diluted basis. In the event any such offer
is accepted, in whole or in part, by the holders of the Series 1 Preferred
Stock, the Corporation shall sell such shares to holders of the Series 1
Preferred Stock for the consideration and on the precise terms set forth in the
Corporation's notice (given under the first two sentences of this paragraph).
In the event that one or more holders of the Series 1 Preferred Stock elects
not to, or fails to, exercise its rights under this Section within the twenty
(20) day period, then the Corporation may issue the remaining shares of capital
stock to third persons but only for the same consideration set forth in the
Corporation's notice (given under the first two sentences of this paragraph)

Conversion Price or (y) $6.00 and (ii) the Common Stock has traded, on the
principal market for the Common Stock, with an average daily volume in excess
of 50,000 shares for a period of 30 consecutive days ending on the day

the Series 1 Preferred Stock pursuant to this Section 9(a) shall be at a price

of the Mandatory Redemption Price (including any accrued and unpaid dividends
to (and including) the Call Date), (A) dividends on the shares of the Series 1
Preferred Stock shall cease to accrue, (B) such shares shall be deemed no
longer outstanding and (C) all rights of the holders thereof as stockholders of
the Corporation (except the right to receive from the Corporation (i) any
moneys payable upon exercise of the Call without interest thereon and (ii) any
shares of Common Stock pursuant to Section 5 hereof) shall cease.

     Upon surrender in accordance with the Call Notice of the certificates for
any such shares so purchased (properly endorsed or assigned for transfer, if
the Board of Directors shall so require and the Call Notice shall so state),
such shares shall be purchased by the Corporation at the applicable Mandatory
Redemption Price.

     Notwithstanding the foregoing, if the Call Notice has been given pursuant
to this Section 9 and any holder of shares of Series 1 Preferred Stock shall,
prior to the close of business on the twentieth (20th) day after receipt of
such Call Notice, give written notice to the Corporation pursuant to Section
5(b) hereof of the conversion of any or all of the shares to be purchased held
by such holder (accompanied by a certificate or certificates for such shares,
duly endorsed or assigned to the Corporation), then (i) the conversion of such
shares to be purchased shall become effective as provided in Section 5 hereof
and (ii) the Corporation's right to Call such shares to be purchased shall
terminate.

and/or (iv) Stock Bonuses to officers, employees, directors and consultants of
the Company and its Affiliates. In addition, Non-Employee Directors shall

     2. Administration.

     2.1 Administration by Board. The Board shall administer the Plan unless
and to the extent that the Board delegates its power and authority to a
Committee as provided in Section 2.3.

     2.2 Power of Board. Subject to the provisions of the Plan, the Board,
acting in its sole discretion, shall have the following power and authority:


       2.2.1 to determine to which of the eligible individuals, and the time or
   times at which, Awards shall be granted;


       2.2.2 to determine the number of shares of Common Stock subject to
   Awards granted under the Plan and, where applicable, the price to be paid
   for the shares of Common Stock subject to each Award;


       2.2.3 to determinate the terms and conditions of each Award (which need
not be identical);


       2.2.4 to interpret the terms of the Plan and Awards granted under it,
   and to establish, amend and revoke rules and regulations for its
   administration (and, in the exercise of this power, may correct any defect,
   omission or inconsistency in the Plan or in any Award Agreement, in a
   manner and to the extent it deemed necessary or desirable);


       2.2.5 to accelerate the exercisability or vesting of any Award;

authority theretofore possessed by the Board, including the power to delegate
to a subcommittee any of the administrative powers the Committee is authorized
to exercise (and, as appropriate, references in the Plan to the Board shall be

individuals who qualify as "non-employee directors" under Rule 16b-3
promulgated under Section 16 of the Exchange Act and as "outside directors"
under Section 162(m) of the Code. If for any reason the Committee does not
satisfy the "non-employee director" requirements of Rule 16b-3 or the "outside
director" requirements of Section 162(m) of the Code, such non-compliance shall
not affect the validity of the awards, interpretations or other actions of the
Committee. The Board may delegate nondiscretionary administrative duties to
such employees of the Company as it deems proper.

released shares from such Option or Stock Appreciation Right shall be available
for future issuance under the Plan. Shares that are subject to an Award that is
forfeited or cancelled or that are withheld in order to pay the purchase price
for shares of Common Stock covered by any Award or to satisfy the tax
withholding obligations associated with any Award under the Plan shall be
available for future issuance under the Plan. Shares of Common Stock available
for issuance under the Plan may be authorized and unissued, held by the Company
in its treasury or otherwise acquired for purposes of the Plan. No fractional
shares of Common Stock shall be issued under the Plan. Subject to adjustment
pursuant to Section 11, the maximum number of shares of Common Stock with
respect to which Options or Stock Appreciation Rights may be granted during any
calendar year to any employee may not exceed 300,000 shares.

     4. Eligibility. Awards may be granted under the Plan to officers,
employees, directors and consultants of the Company or its Affiliates.
Incentive Stock Options may be granted only to employees of the Company or its
Affiliates. Non-Employee Directors shall receive automatic grants of
Nonstatutory Stock Options pursuant to Section 8 of the Plan. The Company may
also, from time to time, assume outstanding awards granted by another company,
whether in connection with an acquisition of such other company or otherwise,
by either (i) granting an Award under the Plan in replacement of the award
assumed by the Company, or (ii) treating the assumed award as if it had been
granted under the Plan.

     5. Options.

     5.1 Option Grant. Subject to the provisions hereof, the Board may grant
Incentive Stock Options and Nonstatutory Stock Options to eligible personnel on
such terms and conditions as the Board deems appropriate.

     5.2 Exercise Price. The exercise price of an Option shall not be less than
the par value of the Common Stock, provided that (i) the exercise price of an
Incentive Stock Option shall not be less than the Fair Market Value of the
Common Stock on the date the Option is granted, and (ii) the exercise price of
an Incentive Stock Option granted to a Ten Percent Stockholder shall not be
less than 110% of the Fair Market Value of the Common Stock on the date the
Option is granted.

     5.3 Option Term. No Option granted under the Plan may be exercisable (if
at all) more than ten (10) years after the date the Option is granted (or, in
the case of an Incentive Stock Option granted to a Ten Percent Stockholder,
five (5) years).

     5.4 Vesting and Exercise of Options. The Board may establish such vesting
and other conditions and restrictions on the exercise of an Option and/or upon
the issuance of Common Stock in connection with the exercise of an Option as it
deems appropriate. Subject to satisfaction of applicable withholding
requirements, once vested and exercisable, an Option may be exercised by
transmitting to the Company: (i) a notice specifying the number of shares to be
purchased and (ii) payment of the exercise price. The exercise price of an
Option may be paid in cash and/or such other form of payment as the Company may
permit.

     5.5 Rights as a Stockholder. No shares of Common Stock shall be issued in
respect of the exercise of an Option until full payment of the exercise price
and the applicable tax withholding obligation with respect to such exercise has
been made or provided for. The holder of an Option shall have no rights as a
stockholder with respect to any shares covered by an Option until the date such
shares are issued. Except as otherwise provided herein, no adjustments shall be
made for dividend distributions or other rights for which the record date is
prior to the date such shares are issued.


                                      G-2
<PAGE>

     5.6 Buy Out and Settlement. The Board, on behalf of the Company, may at
any time offer to buy out any Option on such terms and conditions as the Board
shall establish.

     5.7 Options Non-Transferable. Options granted under the Plan shall not be
transferable or assignable by a Participant, and may not be made subject to
execution, attachment or similar process, otherwise than by will or by the laws
of descent and distribution, and shall be exercisable during the lifetime of a
Participant only by the Participant. Notwithstanding the foregoing, the Board
may determine at the time of grant or thereafter that a Nonstatutory Stock
Option is transferable in whole or part to such persons, under such
circumstances, and subject to such conditions as the Board may prescribe.

     5.8 Assumed Options. In the event the Company assumes an option granted by
another company, the exercise price and the number and nature of shares
issuable upon exercise of such assumed option shall be adjusted appropriately
as determined by the Board. In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option need not be
granted at Fair Market Value on the date of grant and may instead be granted
with a similarly adjusted exercise price.

     5.9 Replacement Options. Without in any way limiting the authority of the
Board to make or not to make grants of Options, the Board shall have the
authority (but not an obligation) to include as part of any Award Agreement a
provision entitling the Participant to a replacement Option in the event the
Participant exercises the Option evidenced by the Award Agreement, in whole or
in part, by surrendering other shares of Common Stock in accordance with the
Plan and the terms and conditions of the Award Agreement.

     6. Stock Appreciation Rights.

     6.1 Stock Appreciation Right Grant. Subject to the provisions hereof, the
Board may award Stock Appreciation Rights to eligible personnel upon such terms
and conditions as it deems appropriate. A Stock Appreciation Right is an Award
entitling the Participant, upon exercise, to receive an amount, in cash or
shares of Common Stock or a combination thereof, as determined by the Board in
its sole discretion, determined with reference to the appreciation, if any, in
the fair market value of Common Stock during the period beginning on the date
the Stock Appreciation Right is granted and ending on the date the Stock
Appreciation Right is exercised.

     6.2 Types of Stock Appreciation Rights. Stock Appreciation Rights may be
awarded under the Plan in conjunction with an Option ("tandem SARs") or
independent of any Option ("stand-alone SARs"). Tandem SARs awarded in
conjunction with a Nonstatutory Stock Option may be awarded either at or after
the time the Nonstatutory Stock Option is granted. Tandem SARs awarded in
conjunction with an Incentive Stock Option may only be awarded at the time the
Incentive Stock Option is granted.

     6.3 Exercisability. Except as otherwise provided herein, a tandem SAR
shall be exercisable only at the same time and to the same extent and subject
to the same conditions as the related Option is exercisable. The exercise of a
tandem SAR shall cancel the related Option to the extent of the shares of
Common Stock with respect to which the Stock Appreciation Right is exercised,
and vice versa. Tandem SARs may be exercised only when the Fair Market Value of
the Common Stock to which it relates exceeds the Option exercise price. The
Board may impose such additional service or vesting conditions upon the
exercise of a Stock Appreciation Right (tandem or stand-alone) as it deems
appropriate.

     6.4 Exercise. A Stock Appreciation Right may be exercised by giving
written notice to the Company identifying the Stock Appreciation Right that is
being exercised, specifying the number of shares covered by the exercise and
containing such other information or statements as the Board may require. The
Board may establish such rules and procedures as it deems appropriate for the
exercise of Stock Appreciation Rights under the Plan. Upon the exercise of a
Stock Appreciation Right, the Participant shall be entitled to receive an
amount (in cash and/or shares of Common Stock as determined by the Board) equal
to the product of (i) the number of shares with respect to which the Stock
Appreciation Right is being exercised and (ii) the difference between the Fair
Market Value of a share of Common Stock on the date the Stock Appreciation
Right is exercised and the Fair Market Value of a share of Common Stock on the
date the Stock Appreciation Right is granted.

     6.5 SARs Non-Transferable. Stock Appreciation Right shall not be
transferable by a Participant other than upon the Participant's death to a
beneficiary designated by the Participant in a manner acceptable to the


                                      G-3
<PAGE>

Board, or, if no designated beneficiary shall survive the Participant, pursuant
to the Participant's will or by the laws of descent and distribution. All Stock
Appreciation Rights shall be exercisable during the Participant's lifetime only
by the Participant. A Tandem SAR shall be transferable, to the extent permitted
above, only with the underlying Option.

     7. Stock Bonus Awards. Subject to the provisions hereof, the Board may
grant Stock Bonus Awards to eligible personnel upon such terms and conditions
as the Board deems appropriate. The terms and conditions of Stock Bonus Awards
may change from time to time, and the terms and conditions of each Award
Agreement need not be identical.

     7.1 Consideration. A Stock Bonus shall be awarded in consideration for
past or future services rendered to the Company or its Affiliates.

     7.2 Vesting. Shares of Common Stock awarded pursuant to a Stock Bonus may,
but need not, be subject to a vesting schedule determined by the Board.

     7.3 Transferability. Shares of Common Stock received pursuant to a Stock
Bonus Award shall be transferable by the Participant only upon such terms and
conditions as are set forth in the Award Agreement, as the Board shall
determine in its discretion, so long as such shares remain subject to the terms
of the Award Agreement.

     8. Non-Employee Director Stock Option Awards. Subject to the provisions
hereof and without further action by the Board, during the term of the Plan:
(i) each Non-Employee Director then in service shall be granted a Nonstatutory
Stock Option to purchase 2,000 shares of Common Stock on the trading day
following the Effective Date, and (ii) each Non-Employee Director then in
service shall be granted a Nonstatutory Stock Option to purchase 2,000 shares
of Common Stock on the trading day following each annual meeting of the
Company's stockholders that occurs at least one year after his or her
commencement of service as a Non-Employee Director. Unless otherwise determined
by the Board, each Option granted pursuant to this Section 8 shall be subject
to the following terms and conditions:

     8.1 Exercise Price. The purchase price per share shall be equal to the
Fair Market Value of the Common Stock on the date the Option is granted.

     8.2 Vesting Conditions. Each Option shall vest and become exercisable in
annual one-third increments on the first, second and third anniversaries of the
date the Option is granted, provided that the Participant remains in the
continuous service on the Board through each applicable anniversary date.

     8.3 Effect of Termination of Service. If a Non-Employee Director's service
terminates for any reason (other than death or Disability) or no reason, then
any Option held by the Non- Employee Director, to the extent not then
exercisable, shall thereupon terminate. Any Option held by the Non-Employee
Director which is exercisable at the time of such termination of service shall
remain exercisable during the ninety (90) day period following such termination
or, if sooner, until the expiration of the stated term of the Option and, to
the extent not exercised within such period, shall thereupon terminate. The
provisions of Section 9.1.1 shall apply in the event a Non-Employee Director's
service terminates due to his or her death or Disability.

     8.4 Capital Transactions; Change in Control. The provisions of Section 11
shall apply.

     8.5 Expiration. Except as otherwise provided herein, if not previously
exercised, each Option shall expire on the tenth anniversary of the date the
Option is granted.

     9. Termination of Employment or Service. Except as specifically provided
in Section 8, and unless otherwise determined by the Board at grant or, if no
rights of the Participant are thereby reduced, thereafter, and subject to
earlier termination in accordance with the provisions hereof, the following
rules apply with regard to Awards held by a Participant (other than Awards
covered by Section 8) at the time of his or her termination of employment or
other service with the Company and its Affiliates:

     9.1 Stock Options and Stock Appreciation Rights.

       9.1.1 If a Participant's employment or service terminates due to his or
   her death or Disability, then (i) any Option or Stock Appreciation Right
   held by the Participant which is not then exercisable shall


                                      G-4
<PAGE>

   terminate, and (ii) any such Option or Stock Appreciation Right may be
   exercised, to the extent otherwise exercisable on the date his or her
   employment or service terminates, by the Participant (or, in the event of
   death, his or her legal representative) at any time within one year from
   the date his or her employment or service terminates, but in no event after
   expiration of the stated term, and, to the extent not exercised within such
   time period, shall thereupon terminate.

       9.1.2 If a Participant's employment or service is terminated by the
   Company or its Affiliates for Cause or if, at the time of a Participant's
   termination, grounds for termination for Cause exist, then, notwithstanding
   anything to the contrary contained herein, any Option or Stock Appreciation
   Right held by the Participant (whether or not otherwise vested) shall
   immediately terminate and cease to be exercisable. "Cause" means (i) in the
   case where there is no employment or consulting agreement between the
   Participant and the Company or its Affiliates or where such an agreement
   exists but does not define "Cause" (or words of like import), a termination
   classified by the Company as a termination due to the participant's
   dishonesty, fraud, insubordination, willful misconduct, refusal to perform
   services or materially unsatisfactory performance of his or her duties, or
   (ii) in the case where there is an employment or consulting agreement
   between the Participant and the Company or its Affiliates, a termination
   that is or would be deemed for "cause" (or words of like import) under such
   agreement.

       9.1.3 If a Participant's employment or service terminates for any reason
   (other than death, Disability or Cause or at a time when Cause exists) or
   no reason, then any Option or Stock Appreciation Right held by the
   Participant, to the extent not then exercisable, shall thereupon terminate.
   Any Option or Stock Appreciation Right held by the Participant which is
   exercisable at the time of such termination of employment or service shall
   remain exercisable during the thirty (30) day period following such
   termination of employment or service or, if sooner, until the expiration of
   the stated term of the Option or Stock Appreciation Right and, to the
   extent not exercised within such period, shall thereupon terminate.

     9.2 Stock Bonuses. If a Participant's employment or service terminates,
then any shares of Common Stock held by the Participant which have not vested
as of the date of termination under the terms of the Award Agreement shall be
forfeited.

     10. Miscellaneous.

     10.1 No Employment or other Service Rights. Nothing in the Plan or any
instrument executed or Award granted pursuant thereto shall confer upon any
Participant or other holder of Awards any right to continue to be employed by
or serve the Company or an Affiliate in the capacity in effect at the time the
Award was granted or shall affect the right of the Company or an Affiliate to
terminate such employment or service.

     10.2 Investment Assurances. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to reflect conditions imposed
under an Award or to comply with applicable securities laws, including, but not
limited to, legends restricting the transfer of the stock.

     10.3 Withholding Obligations. As a condition to the exercise of any Award
or the delivery of any shares of Common Stock pursuant to any Award or the
lapse of restrictions on any Award, or in connection with any other event that
gives rise to a federal or other governmental tax withholding obligation on the
part of the Company relating to an Award, (i) the Company may deduct or
withhold (or cause to be deducted or withheld) from any payment or distribution
to a Participant whether or not pursuant to the Plan or (ii) the Company shall
be entitled to require that the Participant remit cash to the Company (through
payroll deduction or otherwise), in each case in an amount sufficient in the
opinion of the Company to satisfy such withholding obligation. If the event
giving rise to the withholding obligation involves a transfer of shares of
Common Stock, then, unless the applicable Award Agreement provides otherwise,
at the discretion of the Board, the Participant may satisfy the withholding
obligation described under this Section 10.3 by electing to have the Company
withhold shares of Common Stock (which withholding shall be at a rate not in
excess of the statutory minimum rate) or by tendering previously owned shares
of Common Stock, in each case having a Fair Market Value equal to the amount of
tax to be withheld (or by any other mechanism as may be required or appropriate
to conform with local tax and other rules).


                                      G-5
<PAGE>

     11. Adjustments upon Changes in Common Stock.

     11.1 Capitalization Adjustments. If any change is made in the Common Stock
subject to the Plan, or subject to any Award, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange
of shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan shall be appropriately
adjusted in the class(es) and maximum number of securities subject to the Plan
and the maximum number of securities that may be awarded to any employee, and
the outstanding Awards shall be appropriately adjusted in the class(es) and
number of securities and price per share of stock subject to such outstanding
Awards. The Board, the determination of which shall be final, binding and
conclusive, shall make such adjustments. The conversion of any convertible
securities of the Company shall not be treated as a transaction "without
receipt of consideration" by the Company.

     11.2 Change in Control -- Dissolution or Liquidation. In the event of a
dissolution or liquidation of the Company, then Awards outstanding under the
Plan shall terminate if not exercised (if applicable) immediately prior to, or
simultaneous with, such event.

     11.3  Change in Control -- Asset Sale, Merger, Consolidation or Reverse
Merger. In the event of (i) a sale of all or substantially all of the assets of
the Company, (ii) a merger or consolidation in which the Company is not the
surviving corporation or (iii) a reverse merger in which the Company is the
surviving corporation but the shares of Common Stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise, then any surviving
corporation or acquiring corporation shall assume any Awards outstanding under
the Plan or shall substitute similar awards (including an award to acquire the
same consideration paid to the stockholders in the transaction described in
this Section 11.3 for those Awards outstanding under the Plan). In the event
any surviving corporation or acquiring corporation refuses to assume such
Awards or to substitute similar awards for those Awards outstanding under the
Plan, then the vesting of all outstanding Awards (and, if applicable, the time
during which such Awards may be exercised) shall be accelerated in full, and
the Awards shall terminate if not exercised (if applicable) at or prior to such
event.

     12. Amendment and Termination. The Board may amend or terminate the Plan,
provided, however, that no such action may adversely affect the rights of a
Participant under any outstanding Award without the consent of the Participant.
Except as otherwise provided in Section 11, any amendment which would increase
the number of shares of Common Stock for which Awards may be granted under the
Plan (in the aggregate or on an individual basis) or modify the class of
employees eligible to receive Awards under the Plan shall be subject to the
approval of the stockholders of the Company. The Board may amend the terms of
any Award Agreement at any time and from time to time, provided, however, that
any amendment which would adversely affect the rights of the Participant may
not be made without the consent of the Participant.

     13. Effective Date of Plan. The Plan shall become effective at the
Effective Time.

                    INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20. Indemnification of Directors and Officers


Global's Indemnification


     Section 145 of the Delaware General Corporation Law (the "DGCL") empowers
a Delaware corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of such corporation) by reason of the
fact that such person is or was a director, officer, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. A
corporation may, in advance of the final disposition of any civil, criminal,
administrative or investigative action, suit or proceeding, pay the expenses
(including attorneys' fees) incurred by any officer or director in defending
such action, provided that the director or officer undertakes to repay such
amount if it shall ultimately be determined that he or she is not entitled to
be indemnified by the corporation. A corporation may indemnify such person
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding if he or she acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.



     A Delaware corporation may indemnify officers and directors in an action
by or in the right of the corporation to procure a judgment in its favor under
the same conditions, except that no indemnification is permitted without
judicial approval if the officer or director is adjudged to be liable to the
corporation. Where an officer or director is successful on the merits or
otherwise in the defense of any action referred to above, the corporation must
indemnify him or her against the expenses (including attorneys' fees) which he
or she actually and reasonably incurred in connection therewith. The
indemnification provided is not deemed to be exclusive of any other rights to
which an officer or director may be entitled under any corporation's bylaw,
agreement, vote or otherwise.


     In accordance with Section 145 of the DGCL, Section TWELFTH of Global's
certificate of incorporation ("Global's Certificate") provides that Global
shall indemnify each person who is or was a director, officer, employee or
agent of Global (including the heirs, executors, administrators or estate of
such person) or is or was serving at the request of Global as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, to the fullest extent permitted. The indemnification
provided by Global's Certificate shall not be deemed exclusive of any other
rights to which any of those seeking indemnification or advancement of expenses
may be entitled under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office, and
shall continue as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person. Expenses (including attorneys' fees) incurred
in defending a civil, criminal, administrative or investigative action, suit or
proceeding shall be paid by Global in advance of the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of
the indemnified person to repay such amount if it shall ultimately be
determined that he or she is not entitled to be indemnified by Global. Section
ELEVENTH of Global's Certificate provides that a director of Global shall not
be personally liable to Global or its stockholders for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to Global or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit. The
bylaws of Global provide that, to the fullest extent permitted by applicable
law, Global shall indemnify any person who is a party or otherwise involved in
any proceeding by reason of the fact that such person is or was a director or
officer of Global or was serving at the request of Global.

Impax's Indemnification


     Section 317 of the California Corporations Code authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers who are parties or are threatened to be made parties to any
proceeding (with certain exceptions) by reason of the fact that the person is
or was an agent of the corporation, against expenses, judgments, fines,
settlements and other amounts actually and reasonably incurred in connection
with the proceeding if that person acted in good faith and in a manner the
person reasonably believed to be in the best interests of the corporation.
Section 204 of the California Corporations Code provides that this limitation
on liability has no effect on a director's liability (i) for acts or omissions
that involve intentional misconduct or a knowing and culpable violation of law,
(ii) for acts or omissions that a director believes to be contrary to the best
interests of the corporation or its stockholders or that involve the absence of
good faith on the part of the director, (iii) for any transaction from which a
director derived an improper personal benefit, (iv) for acts or omissions that
show a reckless disregard for the director's duty to the corporation or its
shareholders in circumstances in which the director was aware, or should have
been aware, in the ordinary course of performing a director's duties, of a risk
of a serious injury to the corporation or its shareholders, (v) for acts or
omissions that constitute an unexcused pattern of inattention that amounts to
an abdication of the director's duty to the corporation or its shareholders,
(vi) under Section 310 of the California Corporations Code (concerning
contracts or transactions between the corporation and a director) or (vii)
under Section 316 of the California Corporations Code (concerning directors'
liability for improper dividends, loans and guarantees). Section 317 does not
extend to acts or omissions of a director in his capacity as an officer.

     Further, Section 317 has no effect on claims arising under federal or
state securities laws and does not affect the availability of injunctions and
other equitable remedies available to Impax's stockholders for any violation of
a director's fiduciary duty to Impax or its shareholders. Although the validity
and scope of the legislation underlying Section 317 have not yet been
interpreted to any significant extent by the California courts, Section 317 may
relieve directors of monetary liability to Impax for grossly negligent conduct,
including conduct in situations involving attempted takeovers of Impax.

     In accordance with Section 317, the Restated Articles of Incorporation, as

further provide for indemnification of corporate agents to the maximum extent

                                 UNDERTAKINGS

     (a) If the small business issuer is registering securities under Rule 415
of the Securities Act, that small business issuer hereby undertakes that it
will:

     (1) File, during any period in which it offers or sells securities, a
         post-effective amendment to this registration statement to:

        (i) Include any prospectus required by Section 10(a)(3) of the
            Securities Act;

        (ii) Reflect in the prospectus any facts or events which, individually
             or together, represent a fundamental change in the information in
             the registration statement; and

        (iii) Include any additional or changed material information on the
              plan of distribution.

     (2) For determining liability under the Securities Act, treat each
         post-effective amendment as a new registration statement of the
         securities offered, and the offering of the securities at that time to
         be the initial bona fide offering.

     (3) File a post-effective amendment to remove from registration any of
         the securities that remain unsold at the end of the offering.

     (b) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

     (c) The undersigned registrant undertakes that every prospectus: (i) that
is filed pursuant to paragraph (b) immediately preceding, or (ii) that purports
to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and
is used in connection with an offering of securities subject to Rule 415, will
be filed as a part of an amendment to the registration statement and will not
be used until such amendment is effective, and that, for purposes of
determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (d) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934, as amended (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (e) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the small business issuer pursuant to the foregoing provisions, or
otherwise, the small business issuer has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the small business issuer of expenses
incurred or paid by a director, officer or controlling person of the small
business issuer in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the small business issuer will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

     (f) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, or 13 of this form, within one


                                      II-6
<PAGE>

business day of receipt of such request, and to send the incorporated documents
by first class mail or other equally prompt means. This includes information
contained in documents filed subsequent to the effective date of the
registration statement through the date of responding to the request.

     (g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

undersigned, thereunto duly authorized, in the city of Philadelphia, State of

November 8, 1999



Global Pharmaceutical Corporation
Castor & Kensington Avenues
Philadelphia, PA 19124-5694

Ladies and Gentlemen:

     In connection with the Merger (the "Merger") of Impax Pharmaceuticals, Inc.
("Impax") with and into Global Pharmaceutical Corporation ("Global") pursuant to
the Agreement and Plan of Merger ("Merger Agreement"), dated as of July 26,
1999, by and among Global and Impax, you have asked that we deliver to you this
opinion with respect to certain federal income tax consequences of the Merger.
All capitalized terms not otherwise defined herein have the meaning assigned to
them in the Merger Agreement or the Joint Proxy Statement/Prospectus of Global
(the "Joint Proxy Statement/Prospectus"). All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

     We have acted as legal counsel to Global in connection with the Merger. As
such, and for the purpose of rendering this opinion, we have examined and are
relying upon (without any independent investigation or review thereof) the truth
and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents:

     1.   The Merger Agreement;

     2.   The Joint Proxy Statement/Prospectus;

     3.   Representations made to us by Global in an Officer's Certificate
          reproduced as Attachment A hereto;

     4.   Representations made to us by Impax in an Officer's Certificate
          reproduced as Attachment B hereto; and

     5.   Such other documents, records and matters of law as in our judgment
          were necessary or appropriate.



<PAGE>

November 8, 1999
Page 2

     In connection with rendering this opinion, we have assumed (without any
independent investigation or review thereof) that original documents (including
signatures) are authentic, that documents submitted to us as copies conform to
the original documents, and that there has been (or will be by the Effective
Time of the Merger) due execution and delivery of all documents where due
execution and delivery are prerequisites to the effectiveness thereof.

     Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, we
hereby confirm that our opinions regarding the federal income tax consequences
of the Merger are set forth in the Joint Proxy Statement/Prospectus under the
caption "The Merger Agreement--Material Federal Income Tax Consequences."

     In addition to the assumptions set forth above, this opinion is subject to
the exceptions, limitations and qualifications set forth below.

          1. This opinion represents and is based upon our best judgment
     regarding the application of federal income tax laws arising under the
     Code, existing judicial decisions, administrative regulations and published
     rulings and procedures. Our opinion is not binding upon the Internal
     Revenue Service or the courts, and we cannot provide assurance that the
     Internal Revenue Service will not assert a contrary position. Furthermore,
     we cannot provide assurance that future legislative, judicial or
     administrative changes would not, on either a prospective or retroactive
     basis, adversely affect the accuracy of the conclusions stated herein.
     Moreover, we undertake no responsibility to advise you of any new
     developments in the application or interpretation of the federal income tax
     laws as they might relate to this opinion.

          2. This opinion addresses only the matters set forth in the Joint
     Proxy Statement/Prospectus section entitled "The Merger Agreement--Material
     Federal Income Tax Consequences." The opinion does not address any other
     federal, state, local or foreign tax consequences that may result from the
     Merger or any other transaction.

          3. No opinion is expressed as to any transaction other than the Merger
     as described in the Merger Agreement. Moreover, we have assumed that all
     the transactions described in the Merger Agreement have been or will be
     consummated in accordance with the terms of such Merger Agreement and
     without waiver or breach of any material provision thereof and that all of
     the representations, warranties, statements and assumptions upon which we
     have relied remain true and accurate at all relevant times. Any change
     after the date hereof in the facts and circumstances surrounding the
     Merger, or any inaccuracy in the representations, warranties, statements
     and assumptions upon which we have relied may affect the continuing
     validity of the opinion set forth herein. We assume no responsibility to
     inform you of any such change or inaccuracy that may occur or come to our
     attention.

          4. This opinion is intended solely for your benefit and for the
     benefit of the shareholders of Impax and Global. This opinion may not be
     relied upon for any other purpose or by any other person or entity, and may
     not be made available to any other person or entity, without our prior
     written consent.

     We consent to the filing of this opinion as Exhibit 8 to the Registration
Statement on Form S-4 filed on November 9, 1999 filed with the Securities and
Exchange Commission by Global and the reference to this firm under the headings
"Material Federal Income Tax Consequences" and "Legal Matters" in such
Registration Statement, and to the inclusion of our opinion in the Joint Proxy
Statement/Prospectus.



                                          Very truly yours,


                                          /s/ Fulbright & Jaworski L.L.P.

the case of each Stockholder, voting his, her or its shares of Global Stock in
accordance with Section 1 hereof) to cause the resulting vacancy on the Board to
be filled by a representative designated by the Global Directors.


                                       -2-

         (c) In the event that any Impax Designee for any reason ceases to
serve as a member of the Board during the Initial Period, GLOBAL and the
Stockholders hereby agree to use their respective best efforts (including, in
the case of each Stockholder, voting his, her or its shares of Global Stock in
accordance with Section 1 hereof) to cause the resulting vacancy on the Board to
be filled by a representative designated by the Impax Directors.

         (d) To the extent that a person who is a Global Director (or the
entity with which such person is employed or affiliated or which is otherwise
responsible for nominating such particular person as a Global Director) ceases
to hold any shares of Global Stock (or, prior to the Effective Time, any
shares of Series D Preferred Stock of GLOBAL), or otherwise be affiliated with
GLOBAL, such person will no longer be deemed a Global Director hereunder and
shall not participate in the selection of the Global Designees. To the extent
that a person who is an Impax Director (or the entity with which such person is
employed or affiliated or which is otherwise responsible for nominating such
particular person as an Impax Director) ceases to hold any shares of Global
Stock (or, prior to the Effective Time, any shares of Non-D Impax Stock or
Series D Preferred Stock of Impax) or otherwise be affiliated with IMPAX
and/or GLOBAL (after the Merger), such person will no longer be deemed an
Impax Director hereunder and shall not participate in the selection of the
Impax Designees. Such persons will however continue to be bound by the terms of
this Agreement.

         2. Termination. This Agreement will terminate three years after the
date hereof.

         3. Legend. Each certificate evidencing shares of Global Stock subject
to this Stockholders' Agreement and each Global Stock certificate issued in
exchange for or upon the transfer of any such certificate will be stamped or
otherwise imprinted with a legend in substantially the following form:

         "The securities represented by this certificate are subject to certain
         voting agreements specified in that certain Stockholders' Agreement,
         dated as of ________ __, 1999, among certain of the issuer's
         stockholders. A copy of such Stockholders' Agreement will be furnished
         without charge by the issuer to the holder hereof upon written
         request."

         4. Restrictions on Transfer. (a) Prior to the sale, transfer or other
disposition (a "transfer") of any shares of Global Stock (other than in a sale
of shares of Global Common Stock or Global Preferred Stock to the public in
an offering registered under the 1933 Act, or through a broker, dealer or
market-maker pursuant to the provisions of Rule 144 (or any similar rule then in
force) under the 1933 Act (an "Allowed Transfer")) to any person or entity, the
transferring Stockholder will cause the prospective transferee, as a
pre-condition to such transfer, to execute and deliver to the other Stockholders
a counterpart of this Agreement. No such transfer shall be valid and GLOBAL
shall not be required to recognize any such transfer (other than an Allowed
Transfer) in the absence of such execution and delivery of a counterpart of this
Agreement.

                                       -3-

         (b) For a period of 120 days from the Effective Time, no Stockholder
shall sell, make any short sale of, loan, grant an option for the purchase of,
dispose or otherwise transfer any shares of Global Common Stock, Global
Preferred Stock or other capital stock of GLOBAL, or any other securities
convertible, exchangeable or exercisable for or derivative of Global Common
Stock or Global Preferred Stock, now owned or hereafter acquired by him, her
or it, directly or indirectly.

         5. Amendment and Waiver. No modification, amendment or waiver of any
provision of this Agreement will be effective against the Stockholders unless
such modification, amendment or waiver is approved in writing by the holders of
a majority of the shares of Global Common Stock held by the Impax
Stockholders and by the holders of a majority of the shares of Global Common
Stock held by the Global Stockholders, in both instances, assuming the
conversion of all shares of Preferred Stock of Impax or Global, as
applicable. The failure of any party to enforce any of the provisions of this
Agreement will in no way be construed as a waiver of such provisions and will
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

         6. Severability. Whenever possible, each provision of this Agreement
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

         7. Entire Agreement. Except as contemplated by the Merger Agreement,
this document embodies the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way, including without limitation, the Letter of Intent dated March 16,
1999, relating to the Merger, the Shareholder Agreement, dated January 20, 1999,

Agreement will bind and, subject to paragraph 4 hereof, inure to the benefit of
and be enforceable by the Stockholders, any permitted transferees of shares of
Global Stock held by the Stockholders and the respective successors and
assigns of each of them, so long as they hold shares of Global Stock.

         9. Counterparts. This Agreement may be executed in separate
counterparts each of which will be an original and all of which taken together
will constitute one and the same agreement.

         10. Remedies. The Stockholders will be entitled to enforce their rights
under this Agreement specifically (without posting a bond or other security), to
recover damages by reason of any breach of any provision of this Agreement and
to exercise all other rights existing in their favor. The parties hereto agree
and acknowledge that money damages may not be an adequate remedy for breach of
the provisions of this Agreement and that, in addition to other remedies it may
have, any Stockholder may in its sole discretion apply to any court of law or
equity of competent jurisdiction for specific performance and/or injunctive
relief in order to enforce or prevent any violation of the provisions of this
Agreement. If any party hereto shall institute any action or proceeding to
enforce the provisions hereof, any person (including GLOBAL) against whom such
action or proceeding is brought hereby waives the claim or defense therein that
such party has an adequate remedy at law, and such person shall not urge in any
such action or proceeding the claim or defense that such remedy at law exists.

party has specified by prior written notice to the sending party.

         12. Governing Law. The construction, validity and interpretation of

                  WHEREAS, concurrently herewith Global and Impax
Pharmaceuticals, Inc. ("Impax") are entering into an Agreement and Plan of
Merger (the "Merger Agreement");

                  WHEREAS, pursuant to the Merger Agreement, (i) Impax will be

                  WHEREAS, as of the date hereof, Seller owns beneficially and
of record, and has the power to vote, the classes and amounts of securities of
Impax set forth on Schedule A hereto, (the "Existing Securities," together with
securities of Impax acquired by Seller after the date hereof and prior to the
termination hereof, whether upon the exercise of warrants or options, conversion

representations, warranties, covenants and agreements herein contained, the
parties hereby agree as follows, with all capitalized terms used herein and not
otherwise defined herein having the respective meanings ascribed thereto in the
Merger Agreement:


<PAGE>

         1. Agreement to Vote; Proxy.

                  1.1 Voting. Seller hereby agrees that, during the time this
Agreement is in effect, at any meeting of the stockholders of Impax, however
called (including any adjournments or postponements thereof), Seller shall,
except as otherwise agreed to in writing by Global, (a) vote the Impax
Securities in favor of the Merger; (b) vote the Impax Securities against any
action or agreement that would result in a breach of any covenant,
representation or warranty or any other obligation or agreement of Impax under
the Merger Agreement; and (c) vote the Impax Securities against any action or
agreement (other than the Merger Agreement or the transactions contemplated
thereby) that would impede, interfere with, delay, postpone or attempt to
discourage the Merger, including, but not limited to: (i) any extraordinary
corporate transaction, such as a merger, consolidation or other business
combination involving Impax or any of its affiliates, or a public offering of
securities of Impax; (ii) a sale or transfer of a material amount of assets of
Impax or any of its affiliates or a merger, recapitalization or liquidation of
Impax or any of its affiliates; (iii) any change in the management, board of
directors, or other significant personnel, of Impax; (iv) any change in the
present capitalization or dividend policy of Impax or any of its affiliates; or
(v) any material change in the corporate structure or business of Impax or any
of its affiliates. Seller agrees not to exercise any dissenters' rights he, she
or it may have under the California Corporation Code or otherwise with respect
to any of the Impax Securities.

                  1.2 Proxy. Seller hereby grants to Global a proxy to vote the
Impax Securities as indicated in Section 1.1 above. Seller intends this proxy to
be irrevocable and coupled with an interest and will take such further action or
execute such other instruments as may be necessary to effectuate the intent of
this proxy and hereby revokes any proxy previously granted by Seller with
respect to any of the Impax Securities.

         2. Expiration. Global's right to vote the Impax Securities governed
hereby shall terminate upon the first to occur of (a) the Effective Time (as
defined in the Merger Agreement) of the Merger, (b) termination of the Merger
Agreement in accordance with its terms, and (c) written notice of termination of
this Agreement by Global to Seller. This Agreement shall remain in effect until
the Merger Agreement is terminated in accordance with its terms or the
consummation of the Merger.

         3. Representations and Warranties of Seller. Seller hereby represents
and warrants to Global as follows:

                  3.1 Ownership of Impax Securities. On the date hereof, the
Existing Securities are owned of record and beneficially by Seller. Seller has
sole voting power, without restrictions, with respect to all of the Existing
Securities. Except for this Agreement, Seller has not granted any options,
warrant or other right to purchase or acquire from such Seller any interest in
any Existing Securities.

                  3.2 Power, Binding Agreement. Seller has the legal capacity,
power and authority to enter into and perform all of his, her or its obligations
under this Agreement. The execution, delivery and performance of this Agreement
by Seller will not violate any other agreement to which Seller is a party,
including, without limitation, any voting agreement, shareholders' agreement,
partnership agreement or voting trust. This Agreement has been duly and validly
executed and delivered by Seller and constitutes a valid and binding obligation
of Seller enforceable against Seller in accordance with its terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, moratorium and similar
laws affecting creditors' rights and remedies generally.



                                       2
<PAGE>

                  3.3 No Conflicts. The execution and delivery of this Agreement
do not, and the consummation of the transactions contemplated hereby will not,
conflict with or result in any violation of, or default (with or without notice
or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to loss of a material benefit
under, any provision of any loan or credit agreement, note, bond, mortgage,
indenture, lease, or other agreement, instrument, permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Seller or any of his, her or its properties or assets. No consent,
approval, order or authorization of, or registration, declaration, or filing
with, any governmental entity or public body or authority is required by or with
respect to the execution and delivery of this Agreement by Seller and the
consummation by Seller of the transactions contemplated hereby.

                  3.4 Seller's Qualifications and Other Matters.

         (i) Seller is an Accredited Investor, as that term is defined in Rule
501(a) of Regulation D, as promulgated by the Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended.

         (ii) Seller has received a copy of the prospectus, dated December 19,
1995, of Global relating to Global's initial public offering of Global Common
Stock, a copy of Global's Annual Report on Form 10-KSB for the year ended
December 31, 1998, a copy of Global's quarterly report on Form 10-QSB for the
quarter ended March 31, 1999, a copy of the draft Merger Agreement with all
draft Schedules and Exhibits attached thereto and such information relating to
Impax as Seller has requested (collectively, "Written Information") and, prior
to signing this Agreement, Seller has carefully reviewed the Written
Information. No oral representations have been made or oral information
furnished to Seller in connection with the Merger which were in any way
inconsistent with the Written Information. Seller has been fully informed of
negotiations relating to and terms of the Merger Agreement and understands the
business in which Impax and Global, respectively, are and will be engaged and
has such knowledge and experience in financial and business matters, including
knowledge and experience in the pharmaceutical industry, that Seller is capable
of evaluating the merits and risks of the Merger and an investment in the Global
Common Stock, and making an informed investment decision with respect thereto.
Seller has such knowledge and experience in financial and business affairs and
is capable of determining the information necessary to make an informed
decision, requesting such information and utilizing the information he or she
has received to evaluate the merits and risks of the Merger and an investment in
the Global Common Stock. Seller has received such information concerning Global
and Impax and the transactions contemplated by the Merger Agreement, and all
such other information, as he, she or it has deemed necessary or appropriate to
evaluate the merits and risks of the Merger and an investment in the Global
Common Stock and to make such a decision. Further, Seller is a significant
stockholder of Impax and, as such, has been given the opportunity to review the
financial condition of, and is fully familiar with, the business, operations,
prospects and plans of Impax.

         (iii) Seller has had an opportunity to review and discuss the
transactions contemplated by the Merger Agreement with his or her advisors and
management of Impax and Global.

         4. Certain Covenants of Seller. Seller hereby covenants and agrees as
follows:

                  4.1 Restriction on Transfer, Proxies and Non-Interference.
Seller hereby agrees, while this Agreement is in effect, and except as
contemplated hereby, not to, (i) sell, transfer, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Impax Securities, (ii) grant any
proxies, deposit any Impax Securities into a voting trust or enter into a voting
agreement with respect to any Impax Securities or (iii) take any action that
would make any representation or warranty of Seller contained herein untrue or

                  WHEREAS, pursuant to the Merger Agreement, (i) Impax will be

                  WHEREAS, as of the date hereof, Seller owns beneficially and
of record, and has the power to vote, the classes and amounts of securities of
Impax set forth on Schedule A hereto, (the "Existing Securities," together with
securities of Impax acquired by Seller after the date hereof and prior to the
termination hereof, whether upon the exercise of warrants or options, conversion
of convertible securities or otherwise, collectively, referred to herein as the

                  WHEREAS, as a condition to their willingness to enter into the
Merger Agreement, Global has required that Seller agree, and Seller has agreed,
to grant a proxy to vote the Impax Securities on the terms and conditions

                  NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements herein contained, the
parties hereby agree as follows, with all capitalized terms used herein and not
otherwise defined herein having the respective meanings ascribed thereto in the
Merger Agreement:


<PAGE>

         1. Agreement to Vote; Proxy.

                  1.1 Voting. Seller hereby agrees that, during the time this
Agreement is in effect, at any meeting of the stockholders of Impax, however
called (including any adjournments or postponements thereof), Seller shall,
except as otherwise agreed to in writing by Global, (a) vote the Impax
Securities in favor of the Merger; (b) vote the Impax Securities against any
action or agreement that would result in a breach of any covenant,
representation or warranty or any other obligation or agreement of Impax under
the Merger Agreement; and (c) vote the Impax Securities against any action or
agreement (other than the Merger Agreement or the transactions contemplated
thereby) that would impede, interfere with, delay, postpone or attempt to
discourage the Merger, including, but not limited to: (i) any extraordinary
corporate transaction, such as a merger, consolidation or other business
combination involving Impax or any of its affiliates, or a public offering of
securities of Impax; (ii) a sale or transfer of a material amount of assets of
Impax or any of its affiliates or a merger, recapitalization or liquidation of
Impax or any of its affiliates; (iii) any change in the management, board of
directors, or other significant personnel, of Impax; (iv) any change in the
present capitalization or dividend policy of Impax or any of its affiliates; or
(v) any material change in the corporate structure or business of Impax or any
of its affiliates. Seller agrees not to exercise any dissenters' rights he, she
or it may have under the California Corporation Code or otherwise with respect
to any of the Impax Securities.

                  1.2 Proxy. Seller hereby grants to Global a proxy to vote the
Impax Securities as indicated in Section 1.1 above. Seller intends this proxy to
be irrevocable and coupled with an interest and will take such further action or
execute such other instruments as may be necessary to effectuate the intent of
this proxy and hereby revokes any proxy previously granted by Seller with
respect to any of the Impax Securities.

         2. Expiration. Global's right to vote the Impax Securities governed
hereby shall terminate upon the first to occur of (a) the Effective Time (as
defined in the Merger Agreement) of the Merger, (b) termination of the Merger
Agreement in accordance with its terms, and (c) written notice of termination of
this Agreement by Global to Seller. This Agreement shall remain in effect until
the Merger Agreement is terminated in accordance with its terms or the
consummation of the Merger.

         3. Representations and Warranties of Seller. Seller hereby represents
and warrants to Global as follows:

                  3.1 Ownership of Impax Securities. On the date hereof, the
Existing Securities are owned of record and beneficially by Seller. Seller has
sole voting power, without restrictions, with respect to all of the Existing
Securities. Except for this Agreement, Seller has not granted any options,
warrant or other right to purchase or acquire from such Seller any interest in
any Existing Securities.

                  3.2 Power, Binding Agreement. Seller has the legal capacity,
power and authority to enter into and perform all of his, her or its obligations
under this Agreement. The execution, delivery and performance of this Agreement
by Seller will not violate any other agreement to which Seller is a party,
including, without limitation, any voting agreement, shareholders' agreement,
partnership agreement or voting trust. This Agreement has been duly and validly
executed and delivered by Seller and constitutes a valid and binding obligation
of Seller enforceable against Seller in accordance with its terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, moratorium and similar
laws affecting creditors' rights and remedies generally.


                                       2
<PAGE>

                  3.3 No Conflicts. The execution and delivery of this Agreement
do not, and the consummation of the transactions contemplated hereby will not,
conflict with or result in any violation of, or default (with or without notice
or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to loss of a material benefit
under, any provision of any loan or credit agreement, note, bond, mortgage,
indenture, lease, or other agreement, instrument, permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Seller or any of his, her or its properties or assets. No consent,
approval, order or authorization of, or registration, declaration, or filing
with, any governmental entity or public body or authority is required by or with
respect to the execution and delivery of this Agreement by Seller and the
consummation by Seller of the transactions contemplated hereby.

                  3.4 Seller's Qualifications and Other Matters.

         (i) Seller is an Accredited Investor, as that term is defined in Rule
501(a) of Regulation D, as promulgated by the Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended.

         (ii) Seller has received a copy of the prospectus, dated December 19,
1995, of Global relating to Global's initial public offering of Global Common
Stock, a copy of Global's Annual Report on Form 10-KSB for the year ended
December 31, 1998, a copy of Global's quarterly report on Form 10-QSB for the
quarter ended March 31, 1999, a copy of the draft Merger Agreement with all
draft Schedules and Exhibits attached thereto and such information relating to
Impax as Seller has requested (collectively, "Written Information") and, prior
to signing this Agreement, Seller has carefully reviewed the Written
Information. No oral representations have been made or oral information
furnished to Seller in connection with the Merger which were in any way
inconsistent with the Written Information. Seller has been fully informed of
negotiations relating to and terms of the Merger Agreement and understands the
business in which Impax and Global, respectively, are and will be engaged and
has such knowledge and experience in financial and business matters, including
knowledge and experience in the pharmaceutical industry, that Seller is capable
of evaluating the merits and risks of the Merger and an investment in the Global
Common Stock, and making an informed investment decision with respect thereto.
Seller has such knowledge and experience in financial and business affairs and
is capable of determining the information necessary to make an informed
decision, requesting such information and utilizing the information he or she
has received to evaluate the merits and risks of the Merger and an investment in
the Global Common Stock. Seller has received such information concerning Global
and Impax and the transactions contemplated by the Merger Agreement, and all
such other information, as he, she or it has deemed necessary or appropriate to
evaluate the merits and risks of the Merger and an investment in the Global
Common Stock and to make such a decision. Further, Seller is a significant
stockholder of Impax and, as such, has been given the opportunity to review the
financial condition of, and is fully familiar with, the business, operations,
prospects and plans of Impax.

         (iii) Seller has had an opportunity to review and discuss the
transactions contemplated by the Merger Agreement with his or her advisors and
management of Impax and Global.

follows:

                  4.1 Restriction on Transfer, Proxies and Non-Interference.

otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Impax Securities, (ii) grant any
proxies, deposit any Impax Securities into a voting trust or enter into a voting
agreement with respect to any Impax Securities or (iii) take any action that
would make any representation or warranty of Seller contained herein untrue or
incorrect or have the effect of preventing or disabling Seller from performing
his, her or its obligations under this Agreement.

                  4.2 Non Solicitation. Seller agrees not to enter into
negotiations with, or solicit offers from, any party (other than Global)

                  WHEREAS, as of the date hereof, Seller owns beneficially and
of record, and has the power to vote, the classes and amounts of securities of
Impax set forth on Schedule A hereto, (the "Existing Securities," together with
securities of Impax acquired by Seller after the date hereof and prior to the
termination hereof, whether upon the exercise of warrants or options, conversion
of convertible securities or otherwise, collectively, referred to herein as the
"Impax Securities"); and

                  WHEREAS, as a condition to their willingness to enter into the
Merger Agreement, Global has required that Seller agree, and Seller has agreed,
to grant a proxy to vote the Impax Securities on the terms and conditions
provided for herein;

                  NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements herein contained, the
parties hereby agree as follows, with all capitalized terms used herein and not
otherwise defined herein having the respective meanings ascribed thereto in the
Merger Agreement:

<PAGE>

               1. Agreement to Vote; Proxy.

                  1.1 Voting. Seller hereby agrees that, during the time this
Agreement is in effect, at any meeting of the stockholders of Impax, however
called (including any adjournments or postponements thereof), Seller shall,
except as otherwise agreed to in writing by Global, (a) vote the Impax
Securities in favor of the Merger; (b) vote the Impax Securities against any
action or agreement that would result in a breach of any covenant,
representation or warranty or any other obligation or agreement of Impax under
the Merger Agreement; and (c) vote the Impax Securities against any action or
agreement (other than the Merger Agreement or the transactions contemplated
thereby) that would impede, interfere with, delay, postpone or attempt to
discourage the Merger, including, but not limited to: (i) any extraordinary
corporate transaction, such as a merger, consolidation or other business
combination involving Impax or any of its affiliates, or a public offering of
securities of Impax; (ii) a sale or transfer of a material amount of assets of
Impax or any of its affiliates or a merger, recapitalization or liquidation of
Impax or any of its affiliates; (iii) any change in the management, board of
directors, or other significant personnel, of Impax; (iv) any change in the
present capitalization or dividend policy of Impax or any of its affiliates; or
(v) any material change in the corporate structure or business of Impax or any
of its affiliates. Seller agrees not to exercise any dissenters' rights he, she
or it may have under the California Corporation Code or otherwise with respect
to any of the Impax Securities.

                  1.2 Proxy. Seller hereby grants to Global a proxy to vote the
Impax Securities as indicated in Section 1.1 above. Seller intends this proxy to
be irrevocable and coupled with an interest and will take such further action or
execute such other instruments as may be necessary to effectuate the intent of
this proxy and hereby revokes any proxy previously granted by Seller with
respect to any of the Impax Securities.

               2. Expiration. Global's right to vote the Impax Securities
governed hereby shall terminate upon the first to occur of (a) the Effective
Time (as defined in the Merger Agreement) of the Merger, (b) termination of the
Merger Agreement in accordance with its terms, and (c) written notice of
termination of this Agreement by Global to Seller. This Agreement shall remain
in effect until the Merger Agreement is terminated in accordance with its terms
or the consummation of the Merger.

               3. Representations and Warranties of Seller. Seller hereby
represents and warrants to Global as follows:

                  3.1 Ownership of Impax Securities. On the date hereof, the
Existing Securities are owned of record and beneficially by Seller. Seller has
sole voting power, without restrictions, with respect to all of the Existing
Securities. Except for this Agreement, Seller has not granted any options,
warrant or other right to purchase or acquire from such Seller any interest in
any Existing Securities.

                  3.2 Power, Binding Agreement. Seller has the legal capacity,
power and authority to enter into and perform all of his, her or its obligations
under this Agreement. The execution, delivery and performance of this Agreement
by Seller will not violate any other agreement to which Seller is a party,
including, without limitation, any voting agreement, shareholders' agreement,
partnership agreement or voting trust. This Agreement has been duly and validly
executed and delivered by Seller and constitutes a valid and binding obligation
of Seller enforceable against Seller in accordance with its terms, subject to

                                       2

<PAGE>

applicable bankruptcy, insolvency, fraudulent conveyance, moratorium and similar
laws affecting creditors' rights and remedies generally.

                  3.3 No Conflicts. The execution and delivery of this Agreement
do not, and the consummation of the transactions contemplated hereby will not,
conflict with or result in any violation of, or default (with or without notice
or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to loss of a material benefit
under, any provision of any loan or credit agreement, note, bond, mortgage,
indenture, lease, or other agreement, instrument, permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Seller or any of his, her or its properties or assets. No consent,
approval, order or authorization of, or registration, declaration, or filing
with, any governmental entity or public body or authority is required by or with
respect to the execution and delivery of this Agreement by Seller and the
consummation by Seller of the transactions contemplated hereby.

               3.4 Seller's Qualifications and Other Matters.

           (i) Seller is an Accredited Investor, as that term is defined in
Rule 501(a) of Regulation D, as promulgated by the Securities and Exchange
Commission pursuant to the Securities Act of 1933, as amended.

          (ii) Seller has received a copy of the prospectus, dated December 19,
1995, of Global relating to Global's initial public offering of Global Common
Stock, a copy of Global's Annual Report on Form 10-KSB for the year ended
December 31, 1998, a copy of Global's quarterly report on Form 10-QSB for the
quarter ended March 31, 1999, a copy of the draft Merger Agreement with all
draft Schedules and Exhibits attached thereto and such information relating to
Impax as Seller has requested (collectively, "Written Information") and, prior
to signing this Agreement, Seller has carefully reviewed the Written
Information. No oral representations have been made or oral information
furnished to Seller in connection with the Merger which were in any way
inconsistent with the Written Information. Seller has been fully informed of
negotiations relating to and terms of the Merger Agreement and understands the
business in which Impax and Global, respectively, are and will be engaged and
has such knowledge and experience in financial and business matters, including
knowledge and experience in the pharmaceutical industry, that Seller is capable
of evaluating the merits and risks of the Merger and an investment in the Global
Common Stock, and making an informed investment decision with respect thereto.
Seller has such knowledge and experience in financial and business affairs and
is capable of determining the information necessary to make an informed
decision, requesting such information and utilizing the information he or she
has received to evaluate the merits and risks of the Merger and an investment in
the Global Common Stock. Seller has received such information concerning Global
and Impax and the transactions contemplated by the Merger Agreement, and all
such other information, as he, she or it has deemed necessary or appropriate to
evaluate the merits and risks of the Merger and an investment in the Global
Common Stock and to make such a decision. Further, Seller is a significant
stockholder of Impax and, as such, has been given the opportunity to review the
financial condition of, and is fully familiar with, the business, operations,
prospects and plans of Impax.

         (iii) Seller has had an opportunity to review and discuss the
transactions contemplated by the Merger Agreement with his or her advisors and
management of Impax and Global.

agrees as follows:

                  4.1 Restriction on Transfer, Proxies and Non-Interference.

otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Impax Securities, (ii) grant any
proxies, deposit any Impax Securities into a voting trust or enter into a voting
agreement with respect to any Impax Securities or (iii) take any action that
would make any representation or warranty of Seller contained herein untrue or
incorrect or have the effect of preventing or disabling Seller from performing
his, her or its obligations under this Agreement.

                  4.2 Non Solicitation. Seller agrees not to enter into
negotiations with, or solicit offers from, any party (other than Global)

consolidation or other combination of Impax with any other person or entity.

                  4.3 Additional Securities. Seller hereby agrees, while this

convert all of its Common Stock and Series A Preferred Stock of Impax into
Common Stock of Global, in accordance with the Articles of Incorporation of
Impax, and Section 2.01(a) of the Agreement and Plan of Merger, dated as of July
26, 1999, between Global and Impax (the "Merger Agreement"). Such conversions of
the Common Stock and the Series A Preferred Stock shall be automatic and shall
occur, without any further action on the part of the Seller, simultaneously with

standing under the laws of its state of organization and is qualified to do

                  3.2 Corporate Power. The Company has all requisite corporate
power to enter into this Agreement, and has and will have at the Closing Date
all requisite corporate power to sell the Shares and to carry out and perform
its obligations under the terms of this Agreement.

                  3.3 Authorization. All corporate action on the part of the
Company, its directors and stockholders necessary for the authorization,
execution, delivery and performance by the Company of this Agreement and the
consummation of the transactions contemplated herein, and for the authorization,
issuance and delivery of the Shares has been taken or will be taken prior to the
Closing, including, without limitation, the filing of the Certificate of
Designations. This Agreement is a valid and binding obligation of the Company,
enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization and moratorium laws and other laws of general
application affecting enforcement of creditors' rights generally and to general
equitable principles. The execution, delivery and performance by the Company of
this Agreement and compliance herewith and the issuance and sale of the Shares
and the issuance of Common Stock issuable upon conversion of the Shares will not
(a) result in any violation of and will not conflict with, or result in a breach
of any of the terms of, or constitute a default under, the Company's Certificate
of Incorporation or By-Laws, as amended, any mortgage, indenture, agreement,
instrument, judgment, decree, order, rule or regulation or other restriction to
which the Company is a party or by which it is bound or any provision of state
or Federal law to which the Company is subject, or (b) result in the creation of
any mortgage, pledge, lien, encumbrance or charge upon any of the properties or
assets of the Company pursuant to any such term, or (c) result in the
suspension, revocation, impairment, forfeiture or non-renewal of any permit,
license, authorization or approval applicable to the Company's operations or any
of its assets or properties. The Shares, when issued in compliance with the
provisions of this Agreement, will be validly issued, fully paid and
nonassessable; will be free of any liens or encumbrances; and will have the
rights, privileges and preferences as set forth in the Certificate of
Designations. The shares of Common Stock issuable upon conversion of the Shares
have been duly and validly reserved and are not subject to any preemptive rights
or rights of first refusal and, upon issuance, will be validly issued, fully
paid and nonassessable.

                  3.4 Capitalization. Immediately prior to the Closing, the
Company's authorized capital stock will consist of (a) 10,000,000 shares of
common stock, par value $.01 per share ("Common Stock"), of which (i) 4,510,597
shares will be issued and outstanding immediately prior to the Closing, (ii)
750,000 shares have been set aside for issuance to employees, consultants,
independent contractors or directors pursuant to option or incentive plans or
agreements, and (iii) a sufficient number of shares have been set aside for
issuance upon conversion of the presently outstanding shares of the
Corporation's Series A Convertible Preferred Stock, $.01 par value (the "Series
A Stock"), Series B Convertible Preferred Stock, $.01 par value (the "Series B

hereinafter defined) or any previously filed certificate of designations to the
Amended and Restated Certificate of Incorporation of the Company, at the time of
the Closing, there will be no outstanding preemptive, conversion or other
rights, options, warrants or agreements granted or issued by or binding on the
Company for the purchase or acquisition of any shares of its capital stock.

                  3.5 SEC Reports. The Company has filed all required forms,
reports and documents with the Securities and Exchange Commission (the "SEC")
since December 19, 1995 (collectively, the "SEC Reports" and, individually, an
"SEC Report"), all of which SEC Reports have complied in all material respects
with all applicable requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and the Securities Exchange Act of 1934, as amended (the
"Exchange Act").

                  3.6 Absence of Certain Changes. Except as set forth or
otherwise reflected in an SEC Report, since June 30, 1998, the Company has
conducted its business only in the ordinary and usual course and there has not
occurred (i) any material adverse change in the business, financial condition,
operations, results of operations or prospects of the Company or (ii) any change
by the Company in accounting principles or methods, except insofar as may be
required by a change in generally accepted accounting principles.

                  3.7 Outstanding Debt. Except as set forth in the SEC Reports,
the Company has no outstanding indebtedness for borrowed money and is not a
guarantor or otherwise contingently liable for any indebtedness for borrowed
money (including, without limitation, liability by way of agreement, contingent
or otherwise, to purchase, provide funds for payment, supply funds or otherwise
invest in any debtor or otherwise to insure any creditor against loss), except
indebtedness for borrowed money incurred not in excess of $25,000 in the
aggregate. There exists no default under the provisions of any instrument
evidencing any such indebtedness or otherwise or of any agreement relating
thereto, including, without limitation, those included or referred to in the SEC
Reports or Schedule of Exceptions.

                  3.8 Litigation. There is neither pending nor, to the Company's
knowledge and belief, threatened any action, suit, proceeding or claim, or any
basis therefor or threat thereof, whether or not purportedly on behalf of the
Company, to which the Company is or may be named as a party or to which its
property is or may be subject or to the Company's knowledge, after due inquiry,
to which any director or officer of the Company (in his or her capacity as such)
is subject, and in which an unfavorable outcome, ruling or finding in any such
matter or for all such matters taken as a whole might reasonably have a material
adverse effect on the condition, financial or otherwise, prospects, operations
or results of operations of the Company.

                  3.9 Consents. Subject in part to the truth and accuracy of the
Purchasers' representations set forth in this Agreement, no consent, approval,
qualification, order or authorization of, or filing with, any governmental

will take any action hereafter that would cause the loss of such exemption.

                  3.12 Compliance with Other Instruments. The Company is not in
violation of any term of its Certificate of Incorporation or By-Laws, as
amended. The Company is not in violation of any term of any mortgage, indenture,
contract, agreement, instrument, judgment, decree, order, statute, rule or
regulation applicable to the Company or to which the Company is a party or is
subject, the violation of which would have a material adverse effect on the
condition, financial or otherwise, operations, results of operations or
prospects of the Company.

                  3.13 Compliance with Law. The Company is in all material
respects in compliance with all applicable laws, rules, regulations and court or
administrative orders and processes (including, without limitation, any that
relate to consumer protection, health and safety, products and services,
anti-competitive practices, ERISA, equal opportunity, improper payments and
environmental regulation), except where the failure to so comply would not have
a material adverse effect on the condition, financial or otherwise, operations,
results of operations or prospects of the Company. The Company and, to the best
of the Company's knowledge, its directors, officers and employees have not
received any notice from any governmental authority, and to the best of the
Company's knowledge none is threatened, alleging that the Company has violated,
or not complied with, any of the above.

                  3.14 Absence of Undisclosed Liabilities. Except as disclosed
in the financial statements (the "Financial Statements") included in the SEC
Reports, or as incurred in the ordinary course of business subsequent to June
30, 1998, as of the date hereof (i) the Company has no material liability of any
nature (matured or unmatured, fixed or contingent) that was not provided for or
disclosed in the Financial Statements, and (ii) to the best knowledge of the
Company, all


                                      - 5-


<PAGE>



liability reserves established by the Company and set forth in the Financial
Statements were adequate in all material respects for the purposes indicated
therein.

                  3.15 Disclosure. The Company's Form 10-KSB for the fiscal year
ended December 31, 1996 and Form 10-QSB for the fiscal quarter ended June 30,
1998 do not contain any untrue statement of a material fact and do not omit to
state a material fact necessary in order to make the statements contained
therein not misleading in light of the circumstances under which they were made.

                  3.16 Strategic Alliances. Following the Closing Date, the
Company will continue to explore appropriate strategic alliances to enhance
shareholder values.


                                    SECTION 4

                  Representations and Warranties of Purchasers

                  Each Purchaser, severally and not jointly, represents and
warrants with respect to such Purchaser to the Company as follows:

                  4.1 Experience; Accredited Investor Status. (a) Such Purchaser
is experienced in evaluating and investing in development stage companies such
as the Company. Such Purchaser has such knowledge and experience in financing
and business matters that such Purchaser is capable of evaluating the merits and
risks of an investment in the Shares and of making an informed decision, and has
the capacity to protect such Purchaser's own interest in connection with the
transactions contemplated herein.

                           (b) Such Purchaser is an "accredited investor,"
as such term is defined in Rule 501(a) promulgated under the Securities Act

                  4.2 Investment. Such Purchaser is acquiring the Shares for
investment for such Purchaser's own account and not with the view to, or for
resale in connection with, any distribution thereof. Such Purchaser understands
that the Shares are being issued to such Purchaser, and the shares of Common
Stock issuable upon conversion of the Shares are to be issued to such Purchaser,
(i) without registration under the Securities Act by reason of a specified
exemption from the registration provisions of the Securities Act which depends
upon, among other things, the bona fide nature of such Purchaser's investment
intent as expressed herein, and (ii) without qualification under applicable
state securities laws.

                  4.3 Rule 144. Such Purchaser acknowledges that the Shares and
the shares of Common Stock issuable upon conversion of the Shares must be held
indefinitely unless they are subsequently registered under the Securities Act
and qualified under applicable state securities laws


                                      - 6-


<PAGE>



or exemptions from such registration and qualification are available. Such
Purchaser is familiar with Rule 144 promulgated under the Securities Act and
understands the resale limitations imposed thereby.

                  4.4 Access to Data. Such Purchaser has had an opportunity to
discuss the Company's business, management and financial affairs with its
management and has had the opportunity to review the Company's books, records
and facilities.

                  4.5 Restrictions on Transfers. Such Purchaser understands and
agrees as follows:

                  (a) The certificates evidencing the Preferred Stock (and, to
the extent not otherwise registered, the Common Stock issuable upon conversion
thereof), and each certificate issued in transfer of the foregoing, will bear
the following legends (or substantially similar legends):

                  (i)    "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
                         SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER
                         ANY STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
                         OFFERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF
                         WITHOUT SUCH REGISTRATION AND QUALIFICATION OR THE
                         DELIVERY TO THE COMPANY OF AN OPINION OF COUNSEL,
                         REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH
                         DISPOSITION WILL NOT REQUIRE REGISTRATION OF SUCH
                         SECURITIES UNDER THE SECURITIES ACT OF 1933, AS
                         AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS"; and

                  (ii)   any legend required by applicable state securities
                         laws.

                  (b) Such Purchaser will not offer, sell, transfer or otherwise
dispose of any of the Preferred Stock, or any Common Stock issuable upon
conversion thereof, unless (i) an effective registration under the Securities
Act (and an effective qualification under applicable state securities laws, or
exemption therefrom) covers the disposition of such securities, or (ii) such
Purchaser has delivered to the Company an opinion of counsel, reasonably
satisfactory to the Company, that such offer, sale, transfer or other
disposition will not require registration of such securities under the
Securities Act or qualification under any applicable state securities laws.

                  4.6 Authorization. All corporate or partnership action, as the
case may be, on the part of such Purchaser, and its directors and stockholders
or partners, as applicable, necessary for the authorization, execution, delivery
and performance by such Purchaser of this Agreement and the consummation of the
transactions contemplated herein, has been taken or will be taken prior to the
Closing. This Agreement is a valid and binding obligation of such Purchaser,
enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization and moratorium laws and other laws of general
application affecting enforcement of creditors' rights


                                      - 7-


<PAGE>



generally and to general equitable principles. The execution, delivery and
performance by such Purchaser of this Agreement and compliance herewith will not
result in any violation of and will not conflict with, or result in a breach of
any of the terms of, or constitute a default under, such Purchaser's Certificate
of Incorporation or By-Laws or Agreement of Limited Partnership, as applicable.

                  4.7 Principal Place of Business; Place of Negotiations. Such
Purchaser's principal place of business is at the location set forth on the
Schedule of Purchasers. This Agreement was negotiated only in the state of New
York. The Company's offer of Shares to such Purchaser, and such Purchaser's
acceptance of the Company's offer, occurred in the State of New York, unless
otherwise indicated under such Purchaser's name in the Schedule of Exceptions.

                                    SECTION 7

                           Registration of Securities

                  7.1 Certain Definitions. As used in this Section 7, the
following terms shall have the following respective meanings:

                  "Registrable Securities" shall mean, collectively, the shares
of Common Stock issuable upon conversion of the Shares and upon any stock split,
stock dividend, recapitalization or similar event relating thereto.

                  The terms "register," "registered and "registration" shall
refer to a registration effected by preparing and filing a registration
statement in compliance with the Securities Act and applicable rules and

limitation, all registration and filing fees, printing expenses, fees and

be paid in any event by the Company).



                                      - 10-


<PAGE>



                  "Selling Expenses" shall mean all underwriting discounts and
selling commissions, if any, applicable to the sale of securities and all fees
and disbursements of counsel for any Holder (as hereinafter defined).

                  "Holder" shall mean any holder of Registrable Securities which
have not been sold to the public.

                  7.2 Mandatory Registration. The Company shall use its best
efforts to prepare and file with the SEC a registration statement (the
"Registration Statement") for the registration under the Securities Act of all
of the Registrable Securities within 90 days after the Closing Date. The Company
shall use its best efforts to cause such Registration Statement to become
effective as soon as practicable, and to remain effective and current until the
earlier of (i) the redemption by the Company of all the Preferred Stock and (ii)
the sale of all the Registrable Securities (the "Effective Period"); but in no
event later than the earlier to occur of (i) one year after the conversion of
all Shares of Preferred Stock or (ii) December 31, 2001. If the registration of
all of the Registrable Securities is delayed beyond the 90th day after the
Closing for up to 30 additional days (a "30 Day Delay"), then the base price for
computing the Conversion Price (as defined in the Certificate of Designations)
shall be reduced from $2.00 per share to $1.80 per share; and if the
registration of all of such Registrable Securities is delayed beyond the 90th
day after the Closing for up to between 31 and 60 additional days (a "60 Day
Delay"), then such base price shall be reduced from $1.80 per share to $1.60 per
share.

                  Notwithstanding the foregoing, the Company shall not be
required to keep the Registration Statement effective and the Holders shall not
effect any public sale or distribution of Registrable Securities during (i) the
periods that in the good faith judgment of the Board of Directors of the
Company, disclosure of certain confidential information otherwise required to be
disclosed in the Registration Statement would be detrimental to the Company (a
"Detrimental Period") or (ii) the 10 days prior to the date the Company proposes
to make a public announcement of its quarterly or annual earnings (a "Release
Date"), provided that the Company shall furnish each of the Holders, (i) in the
case of a Detrimental Period, with a certificate signed by the President or
Chairman to such effect and (ii) in the case of an Earnings Period, with a
notice of the proposed Release Date, given not less than 10 days prior to such
Release Date; and provided further that in no event shall the number of days
included in such Detrimental Periods, in the aggregate, exceed 90 in any
twelve-month period.

                  7.3 Expenses of Registration. The Company shall bear all
Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to this Agreement. All Selling Expenses
shall be borne by the Holders pro rata on the basis of the number of their
shares so registered, or, in the case of fees and disbursements of counsel, in
such proportions and amounts as the Holders shall mutually agree.

<PAGE>



                  7.4 Registration Procedures. The Company will keep each Holder
advised in writing as to the initiation of the registration and as to the
completion thereof. At its expense, as long as the Company is required to use
its best efforts to keep the Registration Statement effective pursuant to
Section 7.2 hereof, the Company will:

                           (a) Prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in connection
with such Registration Statement as may be necessary to comply with Section 7.2
hereof and with the provisions of the Securities Act with respect to the
disposition of securities covered by such Registration Statement;

                           (b) Furnish such number of prospectuses and other
documents incident thereto, including any amendments of or supplements to the
prospectus, as a Holder from time to time may reasonably request;

                           (c) Notify each seller of Registrable Securities
covered by the Registration Statement 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 the prospectus included in such Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or incomplete in the light of the
circumstances then existing, and at the request of any such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchaser of such shares, such prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading or
incomplete in the light of the circumstances then existing;

                           (d) Cause all such Registrable Securities to be
listed on each securities exchange on which similar securities issued by the
Company are then listed, as set forth in Section 7.9 hereof;

                           (e) Make available for inspection by any seller of
Registrable Securities, any underwriter participating in any disposition
pursuant to the Registration Statement, and any attorney or accountant retained
by any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers and directors to supply all information reasonably requested by any
such seller, underwriter, attorney or accountant in connection with such
Registration Statement: provided, however, that such seller, underwriter,
attorney or accountant shall agree to hold in confidence and trust all
information so provided;

                           (f) Furnish to each selling Holder upon request a
copy of all documents filed with and all correspondence from or to the SEC in
connection with any such offering other than non-substantive cover letters and
the like;


                                      - 12-


<PAGE>



                           (g) Otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make generally available to its
security holders, an earnings statement covering a period of at least twelve
months beginning after the effective date of the Registration Statement, which
earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act. Such statement may be provided to the Company's security holders
through the first annual report mailed to such security holders which includes
financial statements for the appropriate period; provided, however, that if any
Shares are converted into Common Stock prior to the date such earnings statement
is made generally available to the Company's security holders, the Company shall
make such statement generally available as soon as practicable; and

                           (h) Use its best efforts to register or qualify the
Registrable Securities under the securities or blue sky laws of each
jurisdiction as any Holder shall reasonably request, to keep such registration
or qualification in effect for so long as the Registration Statement remains in
effect, and do any and all other acts or things which may be necessary or
advisable to enable such Holder to consummate the public sale or other
disposition in such jurisdictions of the Registrable Securities: provided,
however, that the Company shall not be required to consent to general service of
process in any jurisdiction where it is not then qualified or subject itself to
the payment of any taxes or the jurisdiction of any taxing authority where the
Company would not otherwise be subject.

                  7.5 Indemnification. (a) To the extent permitted by applicable
law, the Company will indemnify each Holder, each of their respective officers,
directors and partners, and each person controlling such Holder, and each
underwriter, if any, and each person who controls any underwriter, against all
claims, losses, damages and liabilities (or actions, proceedings or settlements
in respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any registration, qualification or
compliance required pursuant to this Section 7, or based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or any violation by
the Company of the Securities Act or any rule or regulation thereunder
applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, qualification or compliance,
and will reimburse each such Holder, each of their respective officers,
directors and partners, and each person controlling such Holder, each such
underwriter, if any, and each person who controls any such underwriter, for any
legal and any other expenses as are reasonably incurred in connection with
investigating and defending any such claim, loss, damage, liability or action,
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based on
any untrue statement or omission based upon written information furnished to the
Company by any person to be indemnified hereunder and stated to be specifically
for use therein.

                           (b) To the extent permitted by applicable law, each
Holder will, if securities held by it are included in the securities as to which
such registration, qualification or compliance is being effected, indemnify the
Company, each of its directors and officers and each underwriter, if


                                      - 13-


<PAGE>

any, of the Company's securities covered by such other Registration Statement,
and each person who controls the Company or such underwriter within the meaning
of the Securities Act and the rules and regulations thereunder, each other
Holder, and each of their officers, directors and partners, and each person
controlling such other Holder, against all claims, losses, damages and
liabilities (or actions, proceedings or settlements in respect thereof) arising
out of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any prospectus, offering circular or other document
(including any related registration statement, notification or the like)
incident to any registration, qualification, or compliance required pursuant to
this Section 7, or based on any omission (or alleged omission) to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company and such other
Holders, directors, officers, partners, underwriters, if any, or control persons
for any legal or any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action, in
each case to the extent, but only to the extent, that such untrue statement (or
alleged untrue statement) or omission (or alleged omission) is made in such
registration statement, prospectus, offering circular or other document in
reliance upon and in conformity with written information furnished to the
Company by such Holder and stated to be specifically for use therein: provided,
however, that the obligations of any such Holder hereunder shall be limited to
an amount equal to the proceeds to such Holder of securities sold under such
registration statement, prospectus, offering circular or other document as
contemplated herein.

                           (c) Each party entitled to indemnification under this
Section 7.5 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not unreasonably be withheld), and the Indemnified Party
may participate in such defense at such party's expense; and provided further
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
7.5 unless such failure to notify shall be materially prejudicial to the
Indemnifying Party's ability to defend such action. No Indemnifying Party, in
the defense of any such claim or litigation, shall, except with the consent of
each Indemnified Party (which consent shall not be unreasonably withheld),
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation. Each Indemnified Party shall furnish such information
regarding itself or the claim in question as an Indemnifying Party may
reasonably request in writing and as shall be reasonably required in connection
with the defense of such claim and litigation resulting therefrom. No
Indemnified Party shall, except with the consent of each Indemnifying Party
(which consent shall not be unreasonably withheld), consent to entry of any
judgment or enter into any settlement.

Securities shall furnish to the Company such information regarding such Holder
as the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in this Agreement. If requested by the Company, the Holder will
specifically state that such information is to be used in a prospectus, offering

or prospective holder a right to require the Company to register securities
owned by such holder.

                  7.8 Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the SEC which may permit the sale
of the Registrable Securities to the public without registration, the Company
shall until the tenth anniversary of the Closing Date agree to:

                  (a) Use its best efforts to make and keep public information

manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

                  (c) So long as a Holder owns any Registrable Securities,
furnish to the Holder forthwith upon request a written statement by the Company
as to its compliance with the reporting requirements of Rule 144 and of the
Securities Act and the Exchange Act and such other reports and documents so
filed as the Holder may reasonably request in availing itself of any rule or
regulation of the SEC allowing the Holder to sell any such securities without
registration.

                  7.9 NASDAQ Listing. Prior to the registration of all of the
Registrable Securities pursuant to this Section 7, (i) all applications, filings
and documents necessary to list on the NASDAQ Small Cap Market (the "NASDAQ")
the Registrable Securities shall have been filed and, where applicable,
approved, and (ii) all such Registrable Securities shall have been listed (or
approved for listing subject to issuance) on the NASDAQ.

                  7.10 Additional NASDAQ Listing. Upon the happening of any
event pursuant to which additional shares of Common Stock not otherwise included
in the Registrable Securities shall become issuable upon conversion of the
Preferred Stock, the Company will file all applications, filings and documents
necessary to list, and will use its best efforts to cause the listing of all
such

additional shares of Common Stock on the NASDAQ (or such other national

Agreement.

                              EMPLOYMENT AGREEMENT


         This Employment Agreement, effective as of this __ day of _________,
1999 (the "Effective Date"), is by and among IMPAX LABORATORIES, INC., a
Delaware corporation, with a business address at 30831 Huntwood Ave., Hayward,
California 94544 (the "Company") and CHARLES HSIAO, Ph.D., with a mailing
address at 30831 Huntwood Avenue, Hayward, California 94544 ("Executive").

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein set forth, the Company and Executive agree as follows:

         1. Nature of Employment.

                  1.1 Duties and Responsibilities. Executive shall serve as the
Co-Chief Executive Officer of the Company during the term of this Agreement, and
use his best efforts to promote the interests of the Company and shall devote
his full time and efforts to its business and affairs. Executive shall have
general executive powers and active management over the property, business, and
affairs of the Company, subject always to the direction of the Board of
Directors (the "Board") or its designee.

                  1.2 Other Business Activities. Executive will devote his full
professional time, attention and effort to Company's business. Notwithstanding
the foregoing, Executive shall be entitled to participate in other professional
and business activities to the extent such activities are reasonably likely to
enhance Executive's ability to perform his obligations hereunder, provided that
such activities do not compete with the business of the Company and do not
unreasonably interfere with the then performance of his duties hereunder.

                  1.3 Board of Directors Member. Each year during the term of
this Agreement, the Board of Directors of the Company (the "Board") shall
designate Executive as one of management's slate of candidates to the Board,
shall recommend Executive as a Director to its shareholders, and shall otherwise
use its best efforts to have Executive elected as a Director and to have him
remain as a Director during the entire term of this Agreement, in all instances
subject to satisfaction by the Board of Directors of its fiduciary duties and
obligations.

<PAGE>

         2. Compensation.

                  2.1 Salary. Executive's salary shall be at an initial annual
rate of One Hundred Seventy-Five Thousand Dollars ($175,000.00), subject to
withholding and further subject to discretionary increases in accordance with
the Company's normal review procedures and policies. The salary shall be paid in
substantially equal installments in accordance with the Company's standard
payroll practices, as in effect from time to time.

                  2.2 Bonus. Subject to the achievement of certain short-term
and long-term performance goals established by the Board of Directors of the
Company from time to time, Executive shall be paid quarterly and annual bonuses,
payable in stock and/or cash, to be determined by the Board of Directors of this
Company or its Compensation Committee. Each such bonus shall be paid at the same
time as, and be equal to, the bonus paid to Larry Hsu, Ph.D., and Barry Edwards
for such period.

                  2.3 Medical Insurance and Other Benefits. Executive shall be
entitled to receive full health, dental, vision, and disability insurance, as
well as any other benefits customarily offered to other senior executive
officers of the Company, all upon terms no less favorable to Executive, with all
premiums and costs to be paid by the Company. The Company shall also provide to
Executive, at Company's expense, life insurance coverage at standard premium
rates having a death benefit payable to a beneficiary selected by the Executive
equal to $1,000,000 and disability insurance at standard premium rates which
provides salary replacement benefits, not to exceed $250,000 in the aggregate,
in the event Executive becomes incapacitated. Executive shall be required to
undergo a yearly physical examination, at Company's expense, with a physician of
Executive's choosing, and upon Company's request, deliver a copy of such
physician's report from such examination.

                  2.4 Vacation. Executive shall be entitled to receive four (4)
weeks of paid vacation time annually, such vacation shall accrue daily, provided
however, that in the event the total vacation accrual ever reaches four (4)
weeks, then no further vacation time will accrue until Executive has used his
current annual allotment. Executive may not receive pay rather than vacation
except when Executive leaves the Company. Executive may schedule his vacations
at his discretion so long as the timing of such vacations does not interfere
with his responsibilities to the Company.

                  2.5 Reimbursement of Expenses. The Company shall reimburse
Executive for all out-of-pocket expenses incurred by Executive in performing his
obligations hereunder within thirty (30) days after the date on which Executive
delivers to the Company an itemized statement, accompanied by appropriate
receipts to the extent available, describing the reimbursable expenses incurred.
The expenses to be reimbursed include, without limitation, telephone, fax, air
freight and travel related expenses.

                                       2

         3. Term and Termination.

                  3.1 Term. The term of this Agreement shall commence on the
Effective Date and, unless terminated in accordance with this Section 3, shall
continue until the third anniversary of the Effective Date, and thereafter shall
be automatically renewed for successive periods of one year each, unless
terminated by either party by written notice of termination delivered to the
other party at least six (6) months prior to the expiration date of the initial
term or any renewal term of this Agreement (the "Term").

                  3.2 Termination by the Company. The Company shall have the
right to terminate this Agreement (i) for Cause, as defined below, at any time
and without prior notice, or (ii) for any other reason on thirty (30) days
written notice to Executive.

                      3.2.1 Termination for Cause. The phrase "Cause" means any
of the following:

                            (i) any material breach by Executive of any
provision of Sections 5, 6, 7 or 8 of this Agreement;

                            (ii) any material breach of any other provision of
this Agreement by Executive (other than any such breach resulting from
Executive's incapacity due to physical or mental illness, which shall be
governed by Section 3.2.2 hereof), including without limitation the failure to
satisfactorily perform his duties as provided herein, if that breach is not
remedied within thirty (30) days after written notice to Executive describing
the acts alleged to constitute Cause;

                            (iii) any act of fraud, misappropriation,
embezzlement or similar willful and malicious conduct by Executive against the
Company; or

                            (iv) indictment of Executive for a felony or any
conviction of, or guilty plea by Executive to, a crime involving moral turpitude
if that crime of moral turpitude tends or would reasonably tend to bring the
Company into disrepute.

                      3.2.2 Termination for Death or Disability. For purposes
hereof, the term "disability" shall mean such physical or mental illness as
shall render Executive incapable of substantially performing his duties
hereunder on a regular basis at the Company's offices for a period of three (3)
consecutive months or for a period of six (6) months in any twelve-month period,
all as determined by a physician or psychiatrist, as the case may be, selected
by the Company.

                                       3
<PAGE>

                  3.3 Termination by the Executive. Executive may terminate this
Agreement for any reason upon thirty (30) days advance written notice to the
Company.

         4. Termination Payments.

                  4.1 No Payments. In the event of any termination of this
Agreement by Company for Cause, or by Executive without Good Reason, the Company
shall have no further payment obligations to Executive hereunder, except for
wages and benefits accrued to date and/or provided by applicable law.

                  4.2 Continued Payments. If the Company terminates this
Agreement for any reason other than for Cause, or Executive terminates this
Agreement for Good Reason and in accordance with Section 3.3, then in lieu of
any other payments otherwise required hereunder, the Company shall, subject to
Executive's compliance with Sections 5, 6, 7 and 8 hereof, pay Executive, as
liquidated damages and not as a penalty, (a) within fifteen (15) days after the
termination date, all accrued and unpaid salary and benefits (including accrued
but unused vacation time) through the termination date and (b) the lesser of (i)
an amount equal to his salary payments at the time of the termination, in
accordance with the Company's then payment policy, and benefits provided for
herein during the six-month period following the termination date, and (ii) the
entire amount of the salary remaining due and payable from the date of such
termination to the scheduled expiration of this Agreement; provided, however,
that if such termination occurs prior to the first anniversary of the Effective
Date, then in addition to items (a) and (b) above, Executive shall be entitled
to continue to receive, in accordance with the Company's then payment policy, an
amount equal to his salary payments and, to the extent Executive is not
otherwise employed, health benefits, until the first anniversary of the
Effective Date. In the event that this Agreement is terminated due to the death
or disability of Executive, Company shall pay to Executive a portion of any
bonus otherwise payable to Executive in accordance with Section 2.2 hereof,
prorated to reflect any early termination of this Agreement relative to the
performance period to which the bonus relates.

                  4.3 Continued Medical Coverage. If the Company terminates this
Agreement for any reason other than for Cause, or Executive terminates this
Agreement for Good Reason and in accordance with Section 3.3, then Company shall
maintain, at Company's cost, Executive's health, dental, vision and disability
insurance described in Section 2.3 hereof until the first to occur of (i) the
expiration of eighteen (18) months following such termination; or (ii) Executive
accepts employment which provides health insurance. If the Company terminates
this Agreement for Cause, or Executive terminates this Agreement for any reason
other than Good Reason, Executive shall have the right to maintain, at
Executive's cost, the health, dental, vision and disability insurance described
in Section 2.3 hereof, for a period not to exceed eighteen (18) months or such
longer period as may be required by applicable law, all to the extent permitted
by the applicable insurance carrier.

                  4.4 Certain Definitions.

                           4.4.1 Good Reason. For purposes of this Agreement,
"Good Reason" means (i) the assignment to Executive of any duties or the
substantial reduction of Executive's duties, either of which is inconsistent
with Executive's position as Co-Chief Executive Officer; (ii) any change in
Executive's reporting relationship which results in his not reporting to a
member of the Board of Directors of the Company; (iii) a material reduction in
Executive's salary or benefits not agreed to by Executive; (iv) a requirement of
Executive to relocate to an office that would increase Executive's one-way
commute distance by more than fifty (50) miles; or (v) a Change in Control of
Company, as hereinafter defined.

                           4.4.2 Change in Control of Company. For purposes of
this Agreement, "Change in Control of Company" shall mean the occurrence of any
of the following:

                           (i) Any person or entity acquires ownership or

the Company) representing fifty percent (50%) or more of the combined voting
power of the then outstanding securities of the Company or such successor;

                           (ii) (a) a sale or disposition of assets of the
Company involving fifty percent (50%) or more in value of the assets of the

directly or indirectly, at least fifty-one percent (51%) of the voting power of
the surviving or successor corporation; (c) any transaction pursuant to which
all of the shareholders of the Company immediately prior to the transaction,
hold (immediately after the transaction) less than fifty-one percent (51%) of
the combined voting power of the Company or any successor Company; (d) any other
event or transaction which the Board determines, in its discretion, would
materially alter the structure, ownership or control of the Company;

                                       5
<PAGE>


provided, however, that the consummation of the transactions contemplated by the
Agreement and Plan of Merger, dated as of ___________, 1999, between Impax,

constitute a Change in Control.

of Federal, state or local statute, regulation or court order, provided that
Executive delivers prior written notice to Company of such pending disclosure,
and gives Company a reasonable opportunity to oppose such disclosure with the
applicable authority.

                  5.2 Ownership of Proprietary Information. Executive
acknowledges that all Proprietary Information shall be the sole property of the
Company and its assignees (or, in some cases, its clients, suppliers or
customers), and the Company and its assignees (or, in some cases, its clients,
suppliers or customers) shall be the sole owner of all patents, copyrights,
trade secrets, and all other intellectual property rights in connection
therewith (collectively "Intellectual Property Rights"). The Company's ownership
includes any and all modifications, corrections, updates, changes, improvements,
derivatives and enhancements to the Proprietary Information and the Intellectual
Property Rights therein.

                  5.3 Non-Disclosure. At all times, both during Executive's
employment and after his termination, Executive shall keep in strictest
confidence and trust all Proprietary Information, and shall not reproduce or
disclose any Proprietary Information, or use such Proprietary Information for
his own account or the account of any third party, without the written consent
of the Company, except as may be necessary in the ordinary course of performing
duties as an employee of the Company.

                  5.4 Assignment of Inventions. Executive hereby assigns and
transfers to the Company, Executive's entire right, title and interest, now or
hereafter acquired, in and to all Proprietary Information and Intellectual
Property Rights therein, discovered, originated, made or conceived or learned by
Executive either alone or jointly with others, during the period of Executive's
employment which result, directly or indirectly, from (i) the use of premises or
equipment owned, leased or contracted for by the Company or supplies or
Proprietary Information of the Company, or (ii) work conducted on the time of
the Company, or (iii) work performed for the Company. Executive further
acknowledges that all original works of authorship which are made by Executive
(solely or jointly with others) within the scope of and during the period of his
employment with the Company and which are protectible by copyright are "works
made for hire," as that term is defined in the United States Copyright Act.
Executive understands and agrees that the decision whether or not to
commercialize or market any invention developed by him solely or jointly with
others is within the Company's sole discretion and for the Company's sole
benefit and that no royalty will be due to him as a result of the Company's
efforts to commercialize or market any such invention. Executive hereby waives
all moral rights which he may have or hereafter acquire in any Proprietary
Information and any Intellectual Property Rights therein. Executive will, at the
Company's request, promptly execute a written assignment of title to the Company
for any Proprietary Information and Intellectual Property Rights therein, and a
written waiver of all moral rights therein, and Executive will preserve all such
Proprietary Information as confidential information of the Company.

                  5.5 Notice of Inventions; Execution of Documents. Executive
agrees to give Company prompt written notice of his acquisition or creation of
any Proprietary Information. Executive further agrees as to all Proprietary
Information to assist the Company in every proper way (but at the Company's
expense) to obtain and from time to time enforce patents, copyrights and other
rights and protections relating to inventions in any and all countries, and to
that end agrees to execute all documents for use in applying for and obtaining
such patents, copyrights and other rights and protections on and enforcing
inventions as the Company may desire, together with any assignments thereof to
the Company or persons designated by it. Executive's obligations to assist the
Company in obtaining and enforcing patents, copyrights and other rights and
protections relating to Proprietary Information in any and all countries shall
continue beyond the termination of employment, but the Company shall compensate
Executive at a reasonable rate after such termination for time actually spent,
at the Company's request, on such assistance. In the event the Company is
unable, after reasonable effort, to secure signatures on any documents needed to
effect any assignment hereunder or to apply for or prosecute any patent,
copyright or other right or protection relating to an invention, whether because
of physical or mental incapacity or for any other reason whatsoever, Executive
hereby irrevocably designates and appoints the Company and its duly authorized
officers and agents as his agent and attorney-in-fact, to act for and in his
behalf and stead, to execute and file any such application or applications and
to do all other lawfully permitted acts to further the prosecution and issuance
of patents, copyrights or similar protections thereon with the same legal force
and effect as if executed by him.

                  5.6 Return of Proprietary Information. All Proprietary
Information, including, without limitation, all written materials, records and
documents or other tangible materials made by Executive or coming into his
possession as a result of his employment with Company concerning the business or
affairs of Company shall be the sole property of Company; and, upon the
termination of his employment with Company or upon the request of Company,
Executive shall promptly deliver the same to Company.

                  5.7 Third Party Information. Executive recognizes that the
Company has received and in the future will receive from third parties their
confidential or proprietary information subject to a duty on the Company's part
to maintain the confidentiality of such information and to use it only for
certain limited purposes. Executive agrees that Executive owes the Company and
such third parties, during the term of this Agreement and thereafter, a duty to
hold all such confidential or proprietary information in the strictest
confidence and not to disclose it to any person, firm or corporation or to use
it except as necessary in carrying out the services for the Company consistent
with the Company's agreement with such third party.

         6. Prior Inventions. Executive understands that all inventions, if any,
patented or unpatented, which Executive made prior to Executive's employment are
excluded from the scope of this Agreement. To preclude any possible uncertainty,
Executive has set forth on item 1 of Exhibit A attached hereto a complete list
of all of Executive's prior inventions, including numbers of all patents and
patent applications, and a brief description of all unpatented inventions which
are not the property of a previous employer. Executive represents and covenants
that the list is complete and that, if no items are on the list, Executive has
no such prior inventions. Executive agrees to notify the Company in writing
before Executive makes any disclosure or performs any work on behalf of the
Company which appears to threaten or conflict with proprietary rights which
Executive claims in any invention or idea. Executive agrees that if in the
course of performing services hereunder, Executive incorporates into the
Company's Proprietary Information or otherwise utilizes any invention,
improvement, development, concept, discovery or other proprietary information
owned by Executive or in which Executive has an interest, the Company is hereby
granted and shall have a non-exclusive, royalty-free, perpetual, irrevocable,
worldwide license to make, have made, modify, use and sell such item as part of
or in connection with such Proprietary Information.

         7. Conflicting Obligations.

                  7.1 Trade Secrets of Others. Executive represents that he has
not brought, and will not bring with him to Company, disclose to Company, or use
in the performance of his responsibilities, any devices, materials or documents
of a former employer or other party that are proprietary or are not generally
available to the public, unless he has obtained express written authorization
from such party for their possession and use. The only devices, materials or
documents of a former employer or other party that are proprietary or are not
generally available to the public that Executive will bring to the Company, if
any, are identified on item 2 of Exhibit A attached hereto, and as to each such
item, Executive represents that Executive has obtained express written
authorization for their possession and use and has delivered a copy of such
written authorization to the Company.

Furthermore, Executive covenants and agrees that he will not, whether during the

1999 (the "Effective Date"), is by and among IMPAX LABORATORIES, INC., a
Delaware corporation, with a business address at 30831 Huntwood Ave., Hayward,
California 94544 (the "Company") and Larry Hsu, Ph.D., with a mailing address at

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein set forth, the Company and Executive agree as follows:

         1.  Nature of Employment.

             1.1 Duties and Responsibilities. Executive shall serve as the
President of the Company during the term of this Agreement, and use his best
efforts to promote the interests of the Company and shall devote his full time
and efforts to its business and affairs. Executive shall have general executive
powers and active management over the property, business, and affairs of the
Company, subject always to the direction of the Board of Directors (the "Board")
or its designee.

             1.2 Other Business Activities. Executive will devote his full
professional time, attention and effort to Company's business. Notwithstanding
the foregoing, Executive shall be entitled to participate in other professional
and business activities to the extent such activities are reasonably likely to
enhance Executive's ability to perform his obligations hereunder, provided that
such activities do not compete with the business of the Company and do not
unreasonably interfere with the then performance of his duties hereunder.

             1.3 Board of Directors Member. Each year during the term of this
Agreement, the Board of Directors of the Company (the "Board") shall designate
Executive as one of management's slate of candidates to the Board, shall
recommend Executive as a Director to its shareholders, and shall otherwise use
its best efforts to have Executive elected as a Director and to have him remain
as a Director during the entire term of this Agreement, in all instances subject
to satisfaction by the Board of Directors of its fiduciary duties and
obligations.

         2.  Compensation.

             2.1 Salary. Executive's salary shall be at an initial annual rate
of One Hundred Seventy-Five Thousand Dollars ($175,000.00), subject to
withholding and further subject to discretionary increases in accordance with

the Company's normal review procedures and policies. The salary shall be paid in
substantially equal installments in accordance with the Company's standard
payroll practices, as in effect from time to time.

             2.2 Bonus. Subject to the achievement of certain short-term and
long-term performance goals established by the Board of Directors of the Company
from time to time, Executive shall be paid quarterly and annual bonuses, payable
in stock and/or cash, to be determined by the Board of Directors of this Company
or its Compensation Committee. Each such bonus shall be paid at the same time
as, and be equal to, the bonus paid to Charles Hsiao, Ph.D., and Barry Edwards
for such period.

             2.3 Medical Insurance and Other Benefits. Executive shall be
entitled to receive full health, dental, vision, and disability insurance, as
well as any other benefits customarily offered to other senior executive
officers of the Company, all upon terms no less favorable to Executive, with all
premiums and costs to be paid by the Company. The Company shall also provide to
Executive, at Company's expense, life insurance coverage at standard premium
rates having a death benefit payable to a beneficiary selected by the Executive
equal to $1,000,000 and disability insurance at standard premium rates which
provides salary replacement benefits, not to exceed $250,000 in the aggregate,
in the event Executive becomes incapacitated. Executive shall be required to
undergo a yearly physical examination, at Company's expense, with a physician of
Executive's choosing, and upon Company's request, deliver a copy of such
physician's report from such examination.

             2.4 Vacation. Executive shall be entitled to receive four (4) weeks
of paid vacation time annually, such vacation shall accrue daily, provided
however, that in the event the total vacation accrual ever reaches four (4)
weeks, then no further vacation time will accrue until Executive has used his
current annual allotment. Executive may not receive pay rather than vacation
except when Executive leaves the Company. Executive may schedule his vacations
at his discretion so long as the timing of such vacations does not interfere
with his responsibilities to the Company.

             2.5 Reimbursement of Expenses. The Company shall reimburse
Executive for all out-of-pocket expenses incurred by Executive in performing his
obligations hereunder within thirty (30) days after the date on which Executive
delivers to the Company an itemized statement, accompanied by appropriate
receipts to the extent available, describing the reimbursable expenses incurred.
The expenses to be reimbursed include, without limitation, telephone, fax, air
freight and travel related expenses.

Information that:

                 5.1.1 was known to the Executive prior to the date of
disclosure pursuant to this Agreement and not obtained or derived directly or
indirectly from the Company;

                 5.1.2 is or becomes public or available to the general public

<PAGE>

                 5.1.5 is required to be disclosed pursuant to requirements of
Federal, state or local statute, regulation or court order, provided that

and gives Company a reasonable opportunity to oppose such disclosure with the
applicable authority.

                 5.2 Ownership of Proprietary Information. Executive
acknowledges that all Proprietary Information shall be the sole property of the
Company and its assignees (or, in some cases, its clients, suppliers or
customers), and the Company and its assignees (or, in some cases, its clients,
suppliers or customers) shall be the sole owner of all patents, copyrights,
trade secrets, and all other intellectual property rights in connection
therewith (collectively "Intellectual Property Rights"). The Company's ownership
includes any and all modifications, corrections, updates, changes, improvements,
derivatives and enhancements to the Proprietary Information and the Intellectual
Property Rights therein.

                 5.3 Non-Disclosure. At all times, both during Executive's
employment and after his termination, Executive shall keep in strictest
confidence and trust all Proprietary Information, and shall not reproduce or
disclose any Proprietary Information, or use such Proprietary Information for
his own account or the account of any third party, without the written consent
of the Company, except as may be necessary in the ordinary course of performing
duties as an employee of the Company.

                 5.4 Assignment of Inventions. Executive hereby assigns and
transfers to the Company, Executive's entire right, title and interest, now or
hereafter acquired, in and to all Proprietary Information and Intellectual
Property Rights therein, discovered, originated, made or conceived or learned by
Executive either alone or jointly with others, during the period of Executive's
employment which result, directly or indirectly, from (i) the use of premises or
equipment owned, leased or contracted for by the Company or supplies or
Proprietary Information of the Company, or (ii) work conducted on the time of
the Company, or (iii) work performed for the Company. Executive further
acknowledges that all original works of authorship which are made by Executive
(solely or jointly with others) within the scope of and during the period of his
employment with the Company and which are protectible by copyright are "works
made for hire," as that term is defined in the United States Copyright Act.
Executive understands and agrees that the decision whether or not to
commercialize or market any invention developed by him solely or jointly with
others is within the Company's sole discretion and for the Company's sole
benefit and that no royalty will be due to him as a result of the Company's
efforts to commercialize or market any such invention. Executive hereby waives


                                       7
<PAGE>

all moral rights which he may have or hereafter acquire in any Proprietary
Information and any Intellectual Property Rights therein. Executive will, at the
Company's request, promptly execute a written assignment of title to the Company
for any Proprietary Information and Intellectual Property Rights therein, and a
written waiver of all moral rights therein, and Executive will preserve all such
Proprietary Information as confidential information of the Company.

                 5.5 Notice of Inventions; Execution of Documents. Executive
agrees to give Company prompt written notice of his acquisition or creation of
any Proprietary Information. Executive further agrees as to all Proprietary
Information to assist the Company in every proper way (but at the Company's
expense) to obtain and from time to time enforce patents, copyrights and other
rights and protections relating to inventions in any and all countries, and to
that end agrees to execute all documents for use in applying for and obtaining
such patents, copyrights and other rights and protections on and enforcing
inventions as the Company may desire, together with any assignments thereof to
the Company or persons designated by it. Executive's obligations to assist the
Company in obtaining and enforcing patents, copyrights and other rights and
protections relating to Proprietary Information in any and all countries shall
continue beyond the termination of employment, but the Company shall compensate
Executive at a reasonable rate after such termination for time actually spent,
at the Company's request, on such assistance. In the event the Company is
unable, after reasonable effort, to secure signatures on any documents needed to
effect any assignment hereunder or to apply for or prosecute any patent,
copyright or other right or protection relating to an invention, whether because
of physical or mental incapacity or for any other reason whatsoever, Executive
hereby irrevocably designates and appoints the Company and its duly authorized
officers and agents as his agent and attorney-in-fact, to act for and in his
behalf and stead, to execute and file any such application or applications and
to do all other lawfully permitted acts to further the prosecution and issuance
of patents, copyrights or similar protections thereon with the same legal force
and effect as if executed by him.

                 5.6 Return of Proprietary Information. All Proprietary
Information, including, without limitation, all written materials, records and
documents or other tangible materials made by Executive or coming into his
possession as a result of his employment with Company concerning the business or
affairs of Company shall be the sole property of Company; and, upon the
termination of his employment with Company or upon the request of Company,
Executive shall promptly deliver the same to Company.

                 5.7 Third Party Information. Executive recognizes that the
Company has received and in the future will receive from third parties their
confidential or proprietary information subject to a duty on the Company's part
to maintain the confidentiality of such information and to use it only for
certain limited purposes. Executive agrees that Executive owes the Company and
such third parties, during the term of this Agreement and thereafter, a duty to
hold all such confidential or proprietary information in the strictest
confidence and not to disclose it to any person, firm or corporation or to use
it except as necessary in carrying out the services for the Company consistent
with the Company's agreement with such third party.

         6. Prior Inventions. Executive understands that all inventions, if any,
patented or unpatented, which Executive made prior to Executive's employment are
excluded from the scope of this Agreement. To preclude any possible uncertainty,

of all of Executive's prior inventions, including numbers of all patents and
patent applications, and a brief description of all unpatented inventions which
are not the property of a previous employer. Executive represents and covenants

no such prior inventions. Executive agrees to notify the Company in writing
before Executive makes any disclosure or performs any work on behalf of the
Company which appears to threaten or conflict with proprietary rights which
Executive claims in any invention or idea. Executive agrees that if in the
course of performing services hereunder, Executive incorporates into the
Company's Proprietary Information or otherwise utilizes any invention,
improvement, development, concept, discovery or other proprietary information
owned by Executive or in which Executive has an interest, the Company is hereby
granted and shall have a non-exclusive, royalty-free, perpetual, irrevocable,
worldwide license to make, have made, modify, use and sell such item as part of
or in connection with such Proprietary Information.

available to the public, unless he has obtained express written authorization

Furthermore, Executive covenants and agrees that he will not, whether during the
term of this Agreement or thereafter, whether for his own account or for the

1999 (the "Effective Date"), is by and among IMPAX LABORATORIES, INC., a
Delaware corporation, with a business address at 30831 Huntwood Ave., Hayward,

("Executive").

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein set forth, the Company and Executive agree as follows:

         1. Nature of Employment.

                  1.1 Duties and Responsibilities. Executive shall serve as the
Co-Chief Executive Officer of the Company during the term of this Agreement, and
use his best efforts to promote the interests of the Company and shall devote
his full time and efforts to its business and affairs. Executive shall have
general executive powers and active management over the property, business, and
affairs of the Company, subject always to the direction of the Board of
Directors (the "Board") or its designee.

                  1.2 Other Business Activities. Executive will devote his full
professional time, attention and effort to Company's business. Notwithstanding
the foregoing, Executive shall be entitled to participate in other professional
and business activities to the extent such activities are reasonably likely to
enhance Executive's ability to perform his obligations hereunder, provided that
such activities do not compete with the business of the Company and do not
unreasonably interfere with the then performance of his duties hereunder.

                  1.3 Board of Directors Member. Each year during the term of
this Agreement, the Board of Directors of the Company (the "Board") shall
designate Executive as one of management's slate of candidates to the Board,
shall recommend Executive as a Director to its shareholders, and shall otherwise
use its best efforts to have Executive elected as a Director and to have him
remain as a Director during the entire term of this Agreement, in all instances
subject to satisfaction by the Board of Directors of its fiduciary duties and
obligations.

         2. Compensation.

                  2.1 Salary. Executive's salary shall be at an initial annual
rate of One Hundred Seventy-Five Thousand Dollars ($175,000.00), subject to
withholding and further subject to discretionary increases in accordance with
the Company's normal review procedures and policies. The salary shall be paid in
substantially equal installments in accordance with the Company's standard
payroll practices, as in effect from time to time.


<PAGE>

                  2.2 Bonus. Subject to the achievement of certain short-term
and long-term performance goals established by the Board of Directors of the
Company from time to time, Executive shall be paid quarterly and annual bonuses,
payable in stock and/or cash, to be determined by the Board of Directors of this
Company or its Compensation Committee. Each such bonus shall be paid at the same
time as, and be equal to, the bonus paid to Larry Hsu, Ph.D., and Charles Hsiao,
Ph.D. for such period.

                  2.3 Medical Insurance and Other Benefits. Executive shall be
entitled to receive full health, dental, vision, and disability insurance, as
well as any other benefits customarily offered to other senior executive
officers of the Company, all upon terms no less favorable to Executive, with all
premiums and costs to be paid by the Company. The Company shall also provide to
Executive, at Company's expense, life insurance coverage at standard premium
rates having a death benefit payable to a beneficiary selected by the Executive
equal to $1,000,000 and disability insurance at standard premium rates which
provides salary replacement benefits, not to exceed $250,000 in the aggregate,
in the event Executive becomes incapacitated. Executive shall be required to
undergo a yearly physical examination, at Company's expense, with a physician of
Executive's choosing, and upon Company's request, deliver a copy of such
physician's report from such examination.

                  2.4 Vacation. Executive shall be entitled to receive four (4)
weeks of paid vacation time annually, such vacation shall accrue daily, provided
however, that in the event the total vacation accrual ever reaches four (4)
weeks, then no further vacation time will accrue until Executive has used his
current annual allotment. Executive may not receive pay rather than vacation
except when Executive leaves the Company. Executive may schedule his vacations
at his discretion so long as the timing of such vacations does not interfere
with his responsibilities to the Company.

                  2.5 Reimbursement of Expenses. The Company shall reimburse
Executive for all out-of-pocket expenses incurred by Executive in performing his
obligations hereunder within thirty (30) days after the date on which Executive
delivers to the Company an itemized statement, accompanied by appropriate
receipts to the extent available, describing the reimbursable expenses incurred.
The expenses to be reimbursed include, without limitation, telephone, fax, air
freight and travel related expenses. To the extent permitted by law, the Company
will not withhold Philadelphia city wage taxes for the days Executive travels
out of town on business.

                  4.4 Certain Definitions.

                           4.4.1 Good Reason. For purposes of this Agreement,

during his employment he may create, make, derive, produce, obtain, make known
or learn about certain information which has commercial value in the business in
which the Company is engaged and which is treated by the Company as

                           5.1.3 is obtained subsequent to any disclosure under

                           5.1.5 is required to be disclosed pursuant to
requirements of Federal, state or local statute, regulation or court order,
provided that Executive delivers prior written notice to Company of such pending
disclosure, and gives Company a reasonable opportunity to oppose such disclosure
with the applicable authority.

                  5.2 Ownership of Proprietary Information. Executive
acknowledges that all Proprietary Information shall be the sole property of the
Company and its assignees (or, in some cases, its clients, suppliers or
customers), and the Company and its assignees (or, in some cases, its clients,
suppliers or customers) shall be the sole owner of all patents, copyrights,
trade secrets, and all other intellectual property rights in connection
therewith (collectively "Intellectual Property Rights"). The Company's ownership
includes any and all modifications, corrections, updates, changes, improvements,
derivatives and enhancements to the Proprietary Information and the Intellectual
Property Rights therein.

                  5.3 Non-Disclosure. At all times, both during Executive's
employment and after his termination, Executive shall keep in strictest
confidence and trust all Proprietary Information, and shall not reproduce or
disclose any Proprietary Information, or use such Proprietary Information for
his own account or the account of any third party, without the written consent
of the Company, except as may be necessary in the ordinary course of performing
duties as an employee of the Company.

                  5.4 Assignment of Inventions. Executive hereby assigns and
transfers to the Company, Executive's entire right, title and interest, now or
hereafter acquired, in and to all Proprietary Information and Intellectual
Property Rights therein, discovered, originated, made or conceived or learned by
Executive either alone or jointly with others, during the period of Executive's
employment which result, directly or indirectly, from (i) the use of premises or
equipment owned, leased or contracted for by the Company or supplies or
Proprietary Information of the Company, or (ii) work conducted on the time of
the Company, or (iii) work performed for the Company. Executive further
acknowledges that all original works of authorship which are made by Executive


                                        7
<PAGE>

(solely or jointly with others) within the scope of and during the period of his
employment with the Company and which are protectible by copyright are "works
made for hire," as that term is defined in the United States Copyright Act.
Executive understands and agrees that the decision whether or not to
commercialize or market any invention developed by him solely or jointly with
others is within the Company's sole discretion and for the Company's sole
benefit and that no royalty will be due to him as a result of the Company's
efforts to commercialize or market any such invention. Executive hereby waives
all moral rights which he may have or hereafter acquire in any Proprietary
Information and any Intellectual Property Rights therein. Executive will, at the
Company's request, promptly execute a written assignment of title to the Company
for any Proprietary Information and Intellectual Property Rights therein, and a
written waiver of all moral rights therein, and Executive will preserve all such
Proprietary Information as confidential information of the Company.

                  5.5 Notice of Inventions; Execution of Documents. Executive
agrees to give Company prompt written notice of his acquisition or creation of
any Proprietary Information. Executive further agrees as to all Proprietary
Information to assist the Company in every proper way (but at the Company's
expense) to obtain and from time to time enforce patents, copyrights and other
rights and protections relating to inventions in any and all countries, and to
that end agrees to execute all documents for use in applying for and obtaining
such patents, copyrights and other rights and protections on and enforcing
inventions as the Company may desire, together with any assignments thereof to
the Company or persons designated by it. Executive's obligations to assist the
Company in obtaining and enforcing patents, copyrights and other rights and
protections relating to Proprietary Information in any and all countries shall
continue beyond the termination of employment, but the Company shall compensate
Executive at a reasonable rate after such termination for time actually spent,
at the Company's request, on such assistance. In the event the Company is
unable, after reasonable effort, to secure signatures on any documents needed to
effect any assignment hereunder or to apply for or prosecute any patent,
copyright or other right or protection relating to an invention, whether because
of physical or mental incapacity or for any other reason whatsoever, Executive
hereby irrevocably designates and appoints the Company and its duly authorized
officers and agents as his agent and attorney-in-fact, to act for and in his
behalf and stead, to execute and file any such application or applications and
to do all other lawfully permitted acts to further the prosecution and issuance
of patents, copyrights or similar protections thereon with the same legal force
and effect as if executed by him.

Information, including, without limitation, all written materials, records and
documents or other tangible materials made by Executive or coming into his
possession as a result of his employment with Company concerning the business or
affairs of Company shall be the sole property of Company; and, upon the
termination of his employment with Company or upon the request of Company,
Executive shall promptly deliver the same to Company.

                  5.7 Third Party Information. Executive recognizes that the
Company has received and in the future will receive from third parties their
confidential or proprietary information subject to a duty on the Company's part
to maintain the confidentiality of such information and to use it only for
certain limited purposes. Executive agrees that Executive owes the Company and
such third parties, during the term of this Agreement and thereafter, a duty to
hold all such confidential or proprietary information in the strictest
confidence and not to disclose it to any person, firm or corporation or to use
it except as necessary in carrying out the services for the Company consistent
with the Company's agreement with such third party.

         6. Prior Inventions. Executive understands that all inventions, if any,
patented or unpatented, which Executive made prior to Executive's employment are
excluded from the scope of this Agreement. To preclude any possible uncertainty,
Executive has set forth on item 1 of Exhibit A attached hereto a complete list
of all of Executive's prior inventions, including numbers of all patents and
patent applications, and a brief description of all unpatented inventions which
are not the property of a previous employer. Executive represents and covenants
that the list is complete and that, if no items are on the list, Executive has
no such prior inventions. Executive agrees to notify the Company in writing
before Executive makes any disclosure or performs any work on behalf of the
Company which appears to threaten or conflict with proprietary rights which
Executive claims in any invention or idea. Executive agrees that if in the
course of performing services hereunder, Executive incorporates into the
Company's Proprietary Information or otherwise utilizes any invention,
improvement, development, concept, discovery or other proprietary information
owned by Executive or in which Executive has an interest, the Company is hereby
granted and shall have a non-exclusive, royalty-free, perpetual, irrevocable,
worldwide license to make, have made, modify, use and sell such item as part of

of a former employer or other party that are proprietary or are not generally

Lessor, the Premises, for the term, at the rental, and upon all of the terms,
covenants and conditions set forth in this Lease. Unless otherwise provided
herein, any statement of square footage set forth in this Lease, or that may
have been used in calculating rental, is an approximation which Lessor and

revision whether or not the actual square footage is more or less.

   2.2 Condition. Lessor shall deliver the Premises to Lessee clean and free of
debris on the Commencement Date and warrants to Lessee that the existing
plumbing, fire sprinkler system, lighting, air conditioning, heating, and
loading doors, if any, in the Premises, other than those constructed by Lessee,
shall be in good operating condition on the Commencement Date. If a
non-compliance with said warranty exists as of the Commencement Dale, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify same at Lessor's expense. If Lessee does not

(30) days after the Commencement Date, correction of that non-compliance shall
be the obligation of Lessee at Lessee's sole cost and expense.
<PAGE>

   2.3 Compliance with Covenants, Restrictions and Building Code. Lessor
warrants to Lessee that the improvements on the Premises comply with all
applicable covenants or restrictions of record and applicable building codes,
regulations and ordinances in effect on the Commencement Date. Said warranty
does not apply to the use to which Lessee will put the Premises or to any
Alterations or Utility installations (as defined in Paragraph 7.3(a)) made or to
be made by Lessee. If the Premises do not comply with said warranty, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify the same at Lessor's expense.

   2.4 Acceptance of Premises. Lessee hereby acknowledges: (a) that it has been
advised by the Brokers to satisfy itself with respect to the condition of the
Premises (including but not limited to the electrical and fire sprinkler
systems, security, environmental aspects, compliance with Applicable Law, as
defined in Paragraph 6.3) and the present and future suitability of the Premises
for Lessee's intended use, (b) that Lessee has made such investigation as it
deems necessary with reference to such matters and assumes all responsibility
therefor as the same relate to Lessee's occupancy of the Premises and/or the
term of this Lease, and (c) that neither Lessor, nor any of Lessor's agents, has
made any oral or written representations or warranties with respect to the said
matters other than as set forth in this Lease.

                                     PAGE 1

<PAGE>

   3.3 Delay In Possession. If for any reason Lessor cannot deliver possession
of the Premises to Lessee as agreed herein by the Early Possession Date, if one
is specified in Paragraph 1.4, or, if no Early Possession Date is specified, by
the Commencement Date, Lessor shall not be subject to any liability therefor,
nor shall such failure affect the validity of this Lease, or the obligations of
Lessee hereunder, or extend the term hereof, but in such case, Lessee shall not,
except as otherwise provided herein, be obligated to pay rent or perform any
other obligation of Lessee under the terms of this Lease until Lessor delivers
possession of the Premises to Lessee. If possession of the Premises is not
delivered to Lessee within sixty (60) days after the Commencement Date. Lessee
may, at its option, by notice in writing to Lessor within ten (10) days
thereafter, cancel this Lease, in which event the Parties shall be discharged
from all obligations hereunder; provided, however, that if such written notice
by Lessee is not received by Lessor within said ten (10) day period, Lessee's
right to cancel this Lease shall terminate and be of no further force or effect.
Except as may be otherwise provided, and regardless of when the term actually
commences, if possession is not tendered to Lessee when required by this Lease
and Lessee does not terminate this Lease, as aforesaid, the period free of the
obligation to pay Base Rent, if any, that Lessee would otherwise have enjoyed
shall run from the date of delivery of possession and continue for a period
equal to what Lessee would otherwise have enjoyed under the terms hereof, but
minus any days of delay caused by the acts, changes or omissions of Lessee.

4. Rent.

   4.1 Base Rent. Lessee shall cause payment of Base Rent and other rent or
charges, as the same may be adjusted from time to time, to be received by Lessor
in lawful money of the United States, without offset or deduction, on or before
the day on which it is due under the terms of this Lease. Base Rent and all
other rent and charges for any period during the term hereof which is for less
than one (1) full calendar month shall he prorated based upon the actual number
of days of the calendar month involved. Payment of Base Rent and other charges
shall be made to Lessor at its address stated herein or to such other persons or
at such other addresses as Lessor may from time to time designate in writing to
Lessee.

5. Security Deposit. Lessee shall deposit with Lessor upon execution hereof the
Security Deposit set forth in Paragraph 1.7 as security for Lessee's faithful
performance of Lessee's obligations under this Lease. If Lessee fails to pay
Base Rent or other rent or charges due hereunder, or otherwise Defaults under
this Lease (as defined in Paragraph 13.1), Lessor may use, apply or retain all
or any portion of said Security Deposit for the payment of any amount due Lessor
or to reimburse or compensate Lessor for any liability, cost, expense, loss or
damage (including attorneys' fees) which Lessor may suffer or incur by reason
thereof. If Lessor uses or applies all or any portion of said Security Deposit,
Lessee shall within ten (10) days after written request therefor deposit moneys
with Lessor sufficient to restore said Security Deposit to the full amount
required by this Lease. Any time the Base Rent increases during the term of this
Lease, Lessee shall, upon written request from Lessor, deposit additional moneys
with Lessor sufficient to maintain the same ratio between the Security Deposit
and the Base Rent as those amounts are specified in the Basic Provisions. Lessor
Shall not be required to keep all or any part of the Security Deposit separate
from its general accounts. Lessor shall, at the expiration or earlier
termination of the term hereof and after Lessee has vacated the Premises, return
to Lessee (or, at Lessor's option, to the last assignee, if any, of Lessee's
interest herein), that portion of the Security Deposit not used or applied by
Lessor. Unless otherwise expressly agreed in writing by Lessor, no part of the
Security Deposit shall be considered to be held in trust, to bear interest or
other increment for its use, or to be prepayment for any moneys to be paid by
Lessee under this Lease.

6. Use.

   6.1 Use. Lessee shall use and occupy the Premises only for the purposes set
forth in Paragraph 1.8, or any other use which is comparable thereto, and for no
other purpose. Lessee shall not use or permit the use of the Premises in a
manner that creates waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to, neighboring premises or properties. Lessor
hereby agrees to not unreasonably withhold or delay its consent to any written
request by Lessee, Lessees assignees or subtenants, and by prospective assignees
and subtenants of the Lessee, its assignees and subtenants, for a modification
of said permitted purpose for which the premises may be used or occupied, so
long as the same will not impair the structural integrity of the improvements on
the Premises, the mechanical or electrical systems therein, is not significantly
more burdensome to the Premises and the improvements thereon, and is otherwise
permissible pursuant to this Paragraph 6. If Lessor elects to withhold such
consent, Lessor shall within five (5) business days give a written notification
of same, which notice shall include an explanation of Lessor's reasonable
objections to the change in use.
<PAGE>

   6.2 Hazardous Substances.

       (a) Reportable Uses Require Consent. The term "Hazardous Substance" as
used in this Lease shall mean any product, substance, chemical, material or
waste whose presence, nature, quantity and/or intensity of existence, use,
manufacture, disposal, transportation, spill, release or effect, either by
itself or in combination with other materials expected to be on the Premises, is
either: (i) potentially injurious to the public health, safety or welfare, the
environment or the Premises, (ii) regulated or monitored by any governmental
authority, or (iii) a basis for liability of Lessor to any governmental agency
or third party under any applicable statute or common law theory. Hazardous
Substance shall include, but not be limited to, hydrocarbons, petroleum,
gasoline, crude oil or any products, by-products or fractions thereof. Lessee
shall not engage in any activity in, on or about the Premises which constitutes
a Reportable Use (as hereinafter defined) of Hazardous Substances without the
express prior written consent of Lessor and compliance in a timely manner (at
Lessee's sole cost and expense) with all Applicable Law (as defined in Paragraph
6.3). "Reportable Use" shall mean (i) the installation or use of any above or
below ground storage tank, (ii) the generation, possession, storage, use,
transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with, any governmental authority. Reportable Use shall
also include Lessee's being responsible for the presence in, on or about the
Premises of a Hazardous Substance with respect to which any Applicable Law
requires that a notice be given to persons entering or occupying the Premises or
neighboring properties. Notwithstanding the foregoing, Lessee may, without
Lessor's prior consent, but in compliance with all Applicable Law, use any
ordinary and customary materials reasonably required to be used by Lessee in the
normal course of Lessee's business permitted on the Premises, so long as such
use is not a Reportable Use and does not expose the Premises or neighboring
properties to any meaningful risk of contamination or damage or expose Lessor to
any liability therefor. In addition, Lessor may (but without any obligation to
do so) condition its consent to the use or presence of any Hazardous Substance,
activity or storage tank by Lessee upon Lessee's giving Lessor such additional
assurances as Lessor, in its reasonable discretion, deems necessary to protect
itself, the public, the Premises and the environment against damage,
contamination or injury and/or liability therefrom or therefor, including, but
not limited to, the installation (and removal on or before Lease expiration or
earlier termination) of reasonably necessary protective modifications to the
Premises (such as concrete encasements) and/or the deposit of an additional
Security Deposit under Paragraph 5 hereof.

       (b) Duty to Inform Lessor. If Lessee knows, or has reasonable cause to
believe, that a Hazardous Substance, or a condition involving or resulting from
same, has come to be located in, on, under or about the Premises, other than as
previously consented to by Lessor, Lessee shall immediately give written notice
of such fact to Lessor. Lessee shall also immediately give Lessor a copy of any
statement, report, notice, registration, application, permit, business plan,
license, claim, action or proceeding given to, or received from, any
governmental authority or private party, or persons entering or occupying the
Premises, concerning the presence, spill, release, discharge of, or exposure to,
any Hazardous Substance or contamination in, on, or about the Premises,
including but nor limited to all such documents as may be involved in any
Reportable Uses involving the Premises.

       (c) Indemnification. Lessee shall indemnify, protect, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all loss of rents and/or damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, permits and
attorney's and consultant's fees arising out of or involving any Hazardous
Substance or storage tank brought onto the Premises by or for Lessee or under
Lessee's control. Lessee's obligations under this Paragraph 6 shall include, but
not be limited to, the effects of any contamination or injury to person,
property or the environment created or suffered by Lessee, and the cost of
investigation (including consultant's and attorneys fees and testing), removal,
remediation, restoration and/or abatement thereof, or of any contamination
therein involved, and shall survive the expiration or earlier termination of
this Lease. No termination, cancellation or release agreement entered into by
Lessor and Lessee shall release Lessee from its obligations under this Lease
with respect to Hazardous Substances or storage tanks, unless specifically so
agreed by Lessor in writing at the time of such agreement.
<PAGE>

   6.3 Lessee's Compliance with Law. Except as otherwise provided in this Lease,
Lessee, shall, at Lessee's sole cost and expense, fully, diligently and in a
timely manner, comply with all "Applicable Law;" which term is used in this
Lease to include all laws, rules, regulations, ordinances, directives,
covenants, easements and restrictions of record, permits, the requirements of
any applicable fire insurance underwriter or rating bureau, and the
recommendations or Lessor's engineers and/or consultants, relating in any manner
to the Premises (including but not limited to mailers pertaining to (i)
industrial hygiene, (ii) environmental conditions on, in, under or about the
Premises, including soil and groundwater conditions, and (iii) the use,
generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill or release or any Hazardous Substance or storage
tank), now in effect or which may hereafter come into effect, and whether or not
reflecting a change in policy from any previously existing policy. Lessee shall,
within five (5) days after receipt of Lessor's written request, provide Lessor
with copies of all documents and information, including, but not limited to,
permits, registrations, manifests, applications, reports and certificates,
evidencing Lessee's compliance with any Applicable Law specified by Lessor, and
shall immediately upon receipt, notify Lessor in writing (with copies of any
documents involved) of any threatened or actual claim, notice, citation,
warning, complaint or report pertaining to or involving failure by Lessee or the
Promises to comply with any Applicable Law.

   6.4 Inspection; Compliance. Lessor and Lessor's Lender(s) (as defined in
Paragraph 8.3(a)) shall have the right to enter the Premises at any time, in the
case of an emergency, and otherwise at reasonable times, for the purpose of
inspecting the condition of the Premises and for verifying compliance by Lessee
with this Lease and all Applicable Laws (as defined in Paragraph 6.3), and to
employ experts and/or consultants in connection therewith and/or to advise
Lessor with respect to Lessee's activities, including but not limited to the
installation, operation, use, monitoring, maintenance, or removal of any
Hazardous Substance or storage tank on or from the Premises. The costs and
expenses of any such inspections shall be paid by the party requesting same,
unless a Default or Breach of this Lease, violation of Applicable Law, or a
contamination, caused or materially contributed to by Lessee is found to exist
or be imminent, or unless the inspection is requested or ordered by a
governmental authority as the result of any such existing or imminent violation
or contamination. In any such case, Lessee shall upon request reimburse Lessor
or Lessor's Lender, as the case may be, for the costs and expenses of such
inspections.

recent occupancy. If the Premises have never been occupied, the "Base Premium"
shall be the lowest annual premium reasonably obtainable for the Required
Insurance as of the commencement of the Original Term, assuming the most nominal

Carried By Lessor).

       (b) Lessee shall pay any such Insurance Cost Increase to Lessor within
thirty (30) days after receipt by Lessee or a copy of the premium statement or
other reasonable evidence of the amount due. If the insurance policies
maintained hereunder cover other property besides the Premises, Lessor shall
also deliver to Losses a statement of the amount of such Insurance Cost Increase
attributable only to the Premises showing in reasonable detail the manner in
which such amount was computed. Premiums for policy periods commencing prior to,
or extending beyond, the term of this Lease shall be prorated to coincide with
the corresponding Commencement or Expiration of the Lease term.

       (a) Carried by Lessee. Lessee shall obtain and keep in force during the
term of this Lease a Commercial General Liability policy of insurance
protecting Lessee and Lessor (as an additional insured) against claims for

<PAGE>

all areas appurtenant thereto. Such insurance shall be on an occurence basis
providing single limit coverage in an amount not less than $1,000,000 per
occurrence with an "Additional Insured-Managers or Lessors of Premises"
Endorsement and contain the "Amendment of the Pollution Exclusion" for damage
caused by heat, smoke or fumes from a hostile fire. The policy shall not contain
any intra-insured exclusions as between insured persons or organizations, but
shall include coverage for liability assumed under this Lease. as an "insured
contract" for the performance of Lessee's indemnity obligations under this
Lease. The limits of said insurance required by this Lease or as carried by
Lessee shall not, however, limit the liability of Lessee nor relieve Lessee of
any obligation hereunder. All insurance to be carried by Lessee shall be primary
to and not contributory with any similar insurance carried by Lessor, whose
insurance shall be considered excess insurance only.

       (b) Carried By Lessor. In the event Lessor is the insuring Party, Lessor
shall also maintain liability insurance described in Paragraph 8.2(a), above, in
addition to, and not in lieu of, the insurance required to be maintained by
Lessee. Lessee shall not be named as an additional insured therein.

in force during the term of this Lease a policy or policies in the name of
Lessor, with loss payable to Lessor and to the holders of any mortgages, deeds
of trust or ground leases on the Premises ("Lender(s)"), insuring loss or damage
to the Premises. The amount of such insurance shall be equal to the full
replacement cost of the Premises, as the same shall exist from time to time, or
the amount required by Lenders, but in no event more than the commercially
reasonable and available insurable value thereof if, by reason of the unique
nature or age of the improvements involved, such latter amount is less then full
replacement cost. Lessee Owned Alterations and Utility Installations shall be
insured by Lessee under Paragraph 8.4. If the coverage is available and
commercially appropriate, such policy or policies shall insure against all risks
of direct physical loss or damage (except the perils of flood and/or earthquake
unless required by a Lender), including coverage for any additional costs
resulting from debris removal and reasonable amounts of coverage for the
enforcement of any ordinance or law regulating the reconstruction or replacement

the result of a coveted cause of loss, but not including plate glass insurance.
Said policy or policies shall also contain an agreed valuation provision in lieu
of any coinsurance clause, waiver of subrogation, and inflation guard protection

increases). Said insurance shall provide that in the event the Lease is
terminated by reason of an insured loss, the period of indemnity for such
coverage shall be extended beyond the date of the completion of repairs or
replacement of the Premises, to provide for one full year's loss of rental
revenues from the date of any such loss. Said insurance shall contain an agreed
valuation provision in lieu of any coinsurance clause, and the amount of
coverage shall be adjusted annually to reflect the projected rental income,
property taxes, insurance premium costs and other expenses, if any, otherwise
payable by Lessee, for the next twelve (12) month period.

       (c) Adjacent Premises. If the Premises are part of a larger building, or
if the Premises are part of a group or buildings owned by Lessor which are
adjacent to the Premises, the Lessee shall pay for any increase in the premiums
for the property insurance of such building or buildings if said increase is
caused by Lessee's acts, omissions, use or occupancy of the Premises.

       (d) Tenant's Improvements. Since Lessor is the Insuring Party, the Lessor
shall not be required to insure Lessee Owned Alterations and Utility
Installations unless the item in question has become the property of Lessor
under the terms of this Lease.

   8.4 Lessee's Property Insurance. Subject to the requirements of Paragraph
8.5, Lessee at its cost shall either by separate policy or, at Lessor's option,
by endorsement to a policy already carried, maintain insurance coverage on all
of Lessee's personal property, Lessee Owned Alterations and Utility
installations in, on, or about the Premises similar in coverage to that carried
by the Insuring Party under Paragraph 8.3. Such insurance shall be full

occurrence. The proceeds from any such insurance shall be used by Lessee for the
replacement of personal property or the restoration of Lessee Owned Alterations
and Utility Installations. Lessee shall be the Insuring Party with respect to
the insurance required by this Paragraph 8.4 and shall provide Lessor with
written evidence that such insurance is in force.

and maintaining during the policy term a "General Policyholders Rating" of at
least B+, V, or such other rating as may be required by a Lender having a lien
on the Premises, as set forth in the most current issue of "Best's Insurance
Guide." Lessee shall not do or permit to be done anything which shall invalidate
the insurance policies referred to in this Paragraph 8. Lessee shall cause to he
delivered to Lessor certified copies of, or certificates evidencing the
existence and amounts of, the insurance, and with the additional insureds,
required under Paragraph 8.2(a) and 8.4. No such policy shall be cancelable or
subject to modification except after thirty (30) days prior written notice to
Lessor. Lessee shall at least thirty (30) days prior to the expiration of such
policies, furnish Lessor with evidence of renewals or "insurance binders"
evidencing renewal thereof, or Lessor may order such insurance and charge the
cost thereof to Lessee, which amount shall be payable by Lessee to Lessor upon
demand.

   8.6 Waiver of Subrogation. Without affecting any other rights or remedies,
Lessee and Lessor ("Waiving Party") each hereby release and relieve the other,
and waive their entire right to recover damages (whether in contract or in tort)
against the other, for loss of or damage to the Waiving Party's property arising
out of or incident to the perils required to be insured against under Paragraph
8. The effect of such releases and waivers of the right to recover damages shall
not be limited by the amount of insurance carried or required, or by any
deductibles applicable thereto.

   8.7 Indemnity. Except for Lessor's negligence and/or breach of express
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, permits, attorney's and consultant's fees,
expenses and/or liabilities arising out of, involving, or in dealing with, the
occupancy of the Premises by Lessee, the conduct of Lessee's business, any act,

and out of any Default or Breach by Lessee in the performance in a timely manner
of any obligation on Lessee's part to be performed under this Lease. The
foregoing shall include, but not be limited to, the defense or pursuit of any
claim or any action or proceeding involved therein, and whether or not (in the
case of claims made against Lessor) litigated and/or reduced to judgment, and
whether well founded or not. In case any action or proceeding be brought against
Lessor by reason of any or the foregoing matters, Lessee upon notice from Lessor
shall defend the same at Lessee's expense by counsel reasonably satisfactory to
Lessor and Lessor shall cooperate with Lessee in such defense. Lessor need not
have first paid any such claim in order to be so indemnified.

   8.8 Exemption of Lessor from Liability. Lessor shall not be liable for injury
or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinklers, wires,
appliances, plumbing, air conditioning or lighting fixtures, or from any other
cause, whether the said injury or damage results from conditions arising upon
the Premises or upon other portions of the building of which the Promises are a
part, or from other sources or places, and regardless of whether the cause of
such damage or injury or the means of repairing the same is accessible or not.
Lessor shall not be liable for any damages arising from any act or neglect of
any other tenant of Lessor. Notwithstanding Lessor's negligence or breach of
this Lease, Lessor shall under no circumstances be liable for injury to Lessee's
business or for any loss of income or profit therefrom.

9. Damage or Destruction.

   9.1 Definitions.

       (a) "Premises Partial Damage" shall mean damage or destruction to the
improvements on the Premises, other than Lessee Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is less than 50%
of the then Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land and Lessee
Owned Alterations and Utility Installations.

       (b) "Premises Total Destruction" shell mean damage or destruction to the
Premises, other than Lessee Owned Alterations and Utility Installations the
repair cost of which damage or destruction is 50% or more of the then
Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land and Lessee
Owned Alterations and Utility Installations.

       (c) "Insured Loss" shall mean damage or destruction to improvements on
the Premises, other than Lessee Owned Alterations and Utility Installations,
which was caused by an event required to be covered by the insurance described
in Paragraph 8.3(a), irrespective of any deductible amounts or coverage limits
involved.

       (d) "Replacement Cost" shall mean the cost to repair or rebuild the
improvements owned by Lessor at the time of the occurrence to their condition
existing immediately prior thereto, including demolition, debris removal and
upgrading required by the operation of applicable building codes, ordinances or
laws, and without deduction for depreciation.

       (e) "Hazardous Substance Condition" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the

Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such damage
(but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect. Notwithstanding the foregoing, it the required insurance
was not in force or the insurance proceeds are not sufficient to effect such
repair, the Insuring Party shall promptly contribute the shortage in proceeds as
and when required to complete said repairs. In the event, however, the shortage
in proceeds was due to the fact that, by reason of the unique nature of the
improvements, full replacement cost insurance coverage was not commercially
reasonable and available, Lessor shall have no obligation to pay for the
shortage in insurance proceeds or to fully restore the unique aspects of the
Premises unless Lessee provides Lessor with the funds to cover same, or adequate
assurance thereof, within ten (10) days following receipt of written notice of
such shortage and request therefor. If Lessor receives said funds or adequate
assurance thereof within said ten (10) day period, the party responsible for
making the repairs shall complete them as soon as reasonably possible and this
Lease shall remain in full force and effect. If Lessor does not receive such
funds or assurance within said period, Lessor may nevertheless elect by written
notice to Lessee within ten (10) days thereafter to make such restoration and
repair as is commercially reasonable with Lessor paying any shortage in
proceeds, in which case this Lease shall remain in full force and effect. If in
such case Lessor does not so elect, then this Lease shall terminate sixty (60)
days following the occurrence of the damage or destruction. Unless otherwise
agreed, Lessee shall in no event have any right to reimbursement from Lessor for
any funds contributed by Lessee to repair any such damage or destruction.
Premises Partial Damage due to flood or earthquake shall be subject to Paragraph
9.3 rather than Paragraph 9.2, notwithstanding that there may be some insurance
coverage, but the net proceeds of any such insurance shall be made available for
the repairs if made by either Party.

                                     PAGE 4
<PAGE>


   9.3 Partial Damage-Uninsured Loss. If a Premises Partial Damage that is not
an Insured Loss occurs, unless caused by a negligent or willful act of Lessee
(in which event Lessee shall make repairs at Lessees expense and this Lease
shall continue in full force and effect, but subject to Lessor's rights under
Paragraph 13), Lessor may at Lessor's option, either: (i) repair such damage as
soon as reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) give written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such

totally at Lessee's expense and without reimbursement from Lessor. Lessee shall
provide Lessor with the required funds or satisfactory assurance thereof within
thirty (30) days following Lessee's said commitment. In such event this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
repairs as soon as reasonably possible and the required funds are available. If
Lessee does nor give such notice and provide the funds or assurance thereof
within the times specified above, this Lease shall terminate as of the date
specified in Lessor's notice of termination.

   9.4 Total Destruction. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or nor the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 8.6.

   9.5 Damage Near End of Term. If at any time during the last six (6) months of
the term of this Lease there is damage for which the cost to repair exceeds one
(1) month's Base Rent, whether or not an Insured Loss, Lessor may, at Lessor's
option, terminate this Lease effective sixty (60) days following the date of
occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by, within twenty (20) days following the occurrence of the damage, or
before the expiration of the time provided in such option for its exercise,
whichever is earlier ("Exercise Period"), (i) exercising such option and (ii)
providing Lessor with any shortage in insurance proceeds (or adequate assurance
thereof) needed to make the repairs. If Lessee duly exercises such option during
sold Exercise Period and provides Lessor with funds (or adequate assurance
thereof) to cover any shortage in insurance proceeds, Lessor shall, at Lessor's
expense repair such damage as soon as reasonably possible and this Lease shall
continue in full force and effect. If Lessee fails to exercise such option and
provide such funds or assurance during said Exercise Period, then Lessor may at
Lessor's option terminate this Lease as of the expiration of said sixty (60) day
period following the occurrence of such damage by giving written notice to
Lessee of Lessor's election to do so within ten (10) days after the expiration
of the Exercise Period, notwithstanding any term or provision in the grant of
option to the contrary.

   9.6 Abatement of Rent; Lessee's Remedies.

       (a) In the event of damage described in Paragraph 9.2 (Partial
Damage-Insured), whether or not Lessor or Lessee repairs or restores the
Premises, the Base Rent, Real Property Taxes, insurance premiums, and other
charges, if any, payable by Lessee hereunder for the period during which such
damage, its repair or the restoration continues (not to exceed the period for
which rental value insurance Is required under Paragraph 8.3(b)), shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired. Except for abatement of Base Rent, Real Property Taxes, insurance
premiums, and other charges, if any, as aforesaid, all other obligations of
Lessee hereunder shall be performed by Lessee, and Lessee shall have no claim
against Lessor for any damage suffered by reason of any such repair or
restoration.
<PAGE>

       (b) If Lessor shall be obligated to repair or restore the Premises under
the provisions of this Paragraph 9 and shall not commence, in a substantial and
meaningful way. the repair or restoration of the Premises within ninety (90)
days after such obligation shall accrue, Lessee may, at any time prior to the
commencement of such repair or restoration, give written notice to Lessor and to
any Lenders of which Lessee has actual notice of Lessee's election to terminate
this Lease on a date not less then sixty (60) days following the giving of such
notice. If Lessee gives such notice to Lessor and such Lenders and such repair
or restoration is not commenced within thirty (30) days after receipt of such
notice, this Lease shall terminate as of the date specified in said notice. If
Lessor or a Lender commences the repair or restoration of the Premises within
thirty (30) days after receipt of such notice, this Lease shall continue in full
force and effect. "Commence" as used in this Paragraph shall mean either the
unconditional authorization of the preparation of the required plans, or the
beginning of the actual work on the Premises, whichever first occurs.

   9.7 Hazardous Substance Conditions. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law
and this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option either (i) investigate
and remediate such Hazardous Substance Condition, if required, as soon as
reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) if the estimated cost to investigate
and remediate such condition exceeds twelve (12) times the then monthly Base
Rent or $100,000, whichever is greater, give written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such
Hazardous Substance Condition of Lessor's desire to terminate this Lease as of
the date sixty (60) days following the giving of such notice. In the event
Lessor elects to give such notice of Lessor's Intention to terminate this Lease,
Lessee shall have the right within ten (10) days after the receipt of such
notice to give written notice to Lessor of Lessee's commitment to pay for the
investigation and remediation of such Hazardous Substance Condition totally at
Lessee's expense and without reimbursement from Lessor except to the extent of
an amount equal to twelve (12) times the then monthly Base Rent or $100,000,
whichever is greater. Lessee shall provide Lessor with the funds required of
Lessee or satisfactory assurance thereof within thirty (30) days following
Lessee's said commitment. In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such investigation and remediation
as soon as reasonably possible and the required funds are available. It Lessee
does not give such notice and provide the required funds or assurance thereof
within the times specified above, this Lease shall terminate as of the date
specified in Lessor's notice of termination. If a Hazardous Substance Condition
occurs for which Lessee is not legally responsible, there shall be abatement of
Lessee's obligations under this Lease to the same extent as provided in
Paragraph 9.6(a) for a period of not to exceed twelve (12) months.

   9.8 Termination-Advance Payments. Upon termination of this Lease pursuant to
this Paragraph 9, an equitable adjustment shall be made concerning advance Base
Rent and any other advance payments made by Lessee to Lessor. Lessor shall, in
addition, return to Lessee so much of Lessee's Security Deposit as has not been,
or is not then required to be, used by Lessor under the terms of this Lease.

   9.9 Waive Statutes. Lessor and Lessee agree that the terms of this Lease
shall govern the effect of any damage to or destruction of the Premises with
respect to the termination of this Lease and hereby waive the provisions of any
present or future statute to the extent inconsistent herewith.

10. Real Property Taxes.

    10.1 (a) Payment of Taxes. Lessor shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Premises; provided, however, that
Lessee shall pay, in addition to rent, the amount, if any, by which Real
Property Taxes applicable to the Premises increase over the fiscal tax year
during which the Commencement Date occurs ("Tax Increase"). Subject to Paragraph
10.1 (b), payment of any such Tax Increase shall be made by Lessee within thirty
(30) days error receipt of Lessor's written statement setting forth the amount
due and the computation thereof. Lessee shall promptly furnish Lessor with
satisfactory evidence that such taxes have been paid. If any such taxes to be
paid by Lessee shall cover any period of time prior to or after the expiration
or earlier termination of the term hereof, Lessee's share of such taxes shall be
equitably prorated to cover only the period of time within the tax fiscal year
this Lease is in effect, and Lessor shall reimburse Lessee for any overpayment
after such proration.
<PAGE>

         (b) Advance Payment. In order to insure payment when due and before
delinquency of any or all Real Property Taxes, Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's Tax Increase to be paid in advance
to Lessor by Lessee, either: (i) in a lump sum amount equal to the amount due,
at least twenty (20) days prior to the applicable delinquency date, or (ii)
monthly in advance with the payment of the Base Rent. If Lessor elects to
require payment monthly in advance, the monthly payment shall be that equal
monthly amount which, over the number of months remaining before the month in
which the applicable tax installment would become delinquent (and without
interest thereon), would provide a fund large enough to fully discharge before
delinquency the estimated Tax Increase to be paid. When the actual amount of the
applicable Tax Increase is known, the amount of such equal monthly advance
payment shall be adjusted as required to provide the fund needed to pay the
applicable Tax Increase before delinquency. If the amounts paid to Lessor by
Lessee under the provisions of this Paragraph are insufficient to discharge the
obligations of Lessee to pay such Tax Increase as the same becomes due, Lessee
shall pay to Lessor, upon Lessor's demand, such additional sums as are necessary
to pay such obligation. All moneys paid to Lessor under this Paragraph may be
intermingled with other moneys of Lessor and shall not bear interest. In the
event of a Breach by Lessee in the performance of the obligations of Lessee
under this Lease, then any balance of funds paid to Lessor under the provisions
of this Paragraph may, subject to proration as provided in Paragraph 10.1(a),
at the option of Lessor, be treated as an additional Security Deposit under
Paragraph 5.

         (c) Additional Improvements. Notwithstanding Paragraph 10.1(a) hereof,
Lessee shall pay to Lessor upon demand therefor the entirely of any increase in
Real Property Taxes assessed by reason of Alterations or Utility Installations
placed upon the Premises by Lessee or at Lessee's request.

   10.2 Definition of "Real Property Taxes." As used herein, the term "Real
Properly Taxes" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Premises by any authority
having the direct or indirect power to tax, including any city, state or federal
government, or any school, agricultural, sanitary, fire, street, drainage or
other improvement district thereof, levied against any legal or equitable
interest of Lessor in the Premises or in the real property of which the Premises
are a part, Lessor's right to rent or other income therefrom, and/or Lessor's
business of leasing the Premises. The term "Real Property Taxes" shall also
include any tax, fee, levy, assessment or charge, or any increase therein,
imposed by reason of events occurring, or changes in applicable law taking
effect, during the term of this Lease, including but not limited to a change in
the ownership of the Premises or in the improvements thereon, the execution of
this Lease, or any modification, amendment or transfer thereof, and whether or
not contemplated by the Parties.

                                     PAGE 5

<PAGE>

    10.3 Joint Assessment. If the Premises are not separately assessed, Lessee's
liability shall be an equitable proportion of the Real Property Taxes for all of
the land and improvements included within the tax parcel assessed, such
proportion to be determined by Lessor from the respective valuations assigned in
the assessor's work sheets or such other information as may be reasonably
available. Lessor's reasonable determination thereof, in good faith, shall be
conclusive.

    10.4 Personal Property Taxes. Lessee shall pay prior to delinquency all
taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or elsewhere. When possible, Lessee shall
cause its Trade Fixtures, furnishings, equipment and all other personal property
to be assessed and billed separately from the real property of Lessor. If any of
Lessee's said personal property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee within ten (10) days
after receipt of a written statement setting forth the taxes applicable to
Lessee's property or, at Lessor's option, as provided in Paragraph 10.1(b).

11. Utilities. Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon. If any such services are not
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be
determined by Lessor, of all charges jointly metered with other premises.

12. Assignment and Subletting.

    12.1 Lessor's Consent Required.

         (a) Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or otherwise transfer or encumber (collectively,
"assignment") or sublet all or any part of Lessee's interest in this Lease or in
the Premises without Lessor's prior written consent given under and subject to
the terms of Paragraph 36.

         (b) A change in the control of Lessee shall constitute an assignment
requiring Lessor's consent. The transfer, on a cumulative basis, of twenty-five
percent (25%) or more of the voting control of Lessee shall constitute a change
in control for this purpose.

         (c) The involvement of Lessee or its assets in any transaction, or
series of transactions (by way of merger, sale, acquisition, financing,
refinancing, transfer, leveraged buy-out or otherwise), whether or not a formal
assignment or hypothecation of this Lease or Lessee's assets occurs, which
results or will result in a reduction of the Net Worth of Lessee, as hereinafter
defined, by an amount equal to or greater than twenty-five percent (25%) of such
Net Worth of Lessee as it was represented to Lessor at the time of the execution
by Lessor of this Lease or at the time of the most recent assignment to which
Lessor has consented, or as it exists immediately prior to said transaction or
transactions constituting such reduction, at whichever time said Net Worth of
Lessee was or is greater, shall be considered an assignment of this Lease by
Lessee to which Lessor may reasonably withhold its consent. "Net Worth of
Lessee" for purposes of this Lease shall be the net worth or Lessee (excluding
any guarantors) established under generally accepted accounting principles
consistently applied.

         (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option. be a
Default curable after notice per Paragraph 13.1(c), or a noncurable Breach
without the necessity of any notice and grace period. If Lessor elects to treat
such unconsented to assignment or subletting as a noncurable Breach, Lessor
shall have the right to either: (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("Lessor's Notice"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent (110%) of the Base Rent then
in effect, whichever is greater. Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment being due and payable immediately upon the
determination thereof. Further, in the event of such Breach and market value
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
(without the Lease being considered an encumbrance or any deduction for
depreciation or obsolescence, and considering the Premises at its highest and
best use and in good condition), or one hundred ten percent (110%) of the price
previously in effect, whichever is greater, (ii) any index-oriented rental or
price adjustment formulas contained in this Lease shall be adjusted to require
that the base index be determined with reference to the index applicable to the
time of such adjustment, and (iii) any fixed rental adjustments scheduled during
the remainder of the Lease term shall be increased in the same ratio as the new
market rental bears to the Base Rent in affect immediately prior to the market
value adjustment.

         (e) Lessee's remedy for any breach of this Paragraph 12.1 by Lessor
shall be limited to compensatory damages and injunctive relief.
<PAGE>

    12.2 Terms and Conditions Applicable to Assignment and Subletting.

         (a) Regardless of Lessor's consent, any assignment or subletting shall
not: (i) be effective without the express written assumption by such assignee or
sublessee of the obligations of Lessee under this Lease, (ii) release Lessee of
any obligations hereunder. or (iii) alter the primary liability of Lessee for
the payment of Base Rent and other sums due Lessor hereunder or for the
performance of any other obligations to be performed by Lessee under this Lease.

         (b) Lessor may accept any rent or performance of Lessee's obligations
from any person other than Lessee pending approval or disapproval of an
assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of any rent or performance shall constitute a waiver or
estoppel of Lessor's right to exercise its remedies for the Default or Breach by
Lessee of any of the terms, covenants or conditions of this Lease.

         (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent sublettings and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent, and such
action shall not relieve such persons from liability under this Lease or
sublease.

         (d) In the event of any Default or Breach of Lessee's obligations under
this Lease, Lessor may proceed directly against Lessee, any Guarantors or any
one else responsible for the performance of the Lessee's obligations under this
Lease, including the sublessee, without first exhausting Lessor's remedies
against any other person or entity responsible therefor to Lessor, or any
security held by Lessor or Lessee.

         (e) Each request for consent to an assignment or subletting shall be in
writing, accompanied by information relevant to Lessor's determination as to the
financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a non-refundable
deposit of $1,000 or ten percent (10%) of the current monthly Base Rent,
whichever is greater, as reasonable consideration for Lessor's considering and
processing the request for consent. Lessee agrees to provide Lessor with such
other or additional information and/or documentation as may be reasonably
requested by Lessor.

         (f) Any assignee of, or sublessee under, this Lease shall, by reason of
accepting such assignment or entering into such sublease, be deemed, for the
benefit of Lessor, to have assumed and agreed to conform and comply with each
and every term, covenant, condition and obligation herein to be observed or
performed by Lessee during the term of said assignment or sublease, other then
such obligations as are contrary to or inconsistent with provisions of an
assignment or sublease to which Lessor has specifically consented in writing.

         (g) The occurrence of a transaction described in Paragraph 12.1 (c)
shall give Lessor the right (but not the obligation) to require that the
Security Deposit be increased to an amount equal to six (6) times the then
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the
amount required to establish such Security Deposit a condition to Lessor's
consent to such transaction.

         (h) Lessor, as a condition to giving its consent to any assignment or
subletting, may require that the amount and adjustment structure of the rent
payable under this Lease be adjusted to what is then the market value and/or
adjustment structure for property similar to the Premises as then constituted.
<PAGE>

    12.3 Additional Terms and Conditions Applicable to Subletting. The following
terms and conditions shall apply to any subletting by Lessee of all or any part
of the Promises and shall be deemed included in all subleases under this Lease
whether or not expressly incorporated therein:

         (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and Income arising from any sublease of all or a portion
of the Premises heretofore or hereafter made by Lessee, and Lessor may collect
such rent and income and apply same toward Lessee's obligations under this
Lease; provided, however, that until a Breach (as defined in Paragraph 13.1)
shall occur in the performance of Lessee's obligations under this Lease, Lessee
may, except as otherwise provided in this Lease, receive, collect and enjoy the
rents accruing under such sublease. Lessor shall not, by reason of this or any
other assignment of such sublease to Lessor, nor by reason of the collection of
the rents from a sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a Breach
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents and other charges due and to become due under the sublease.
Sublessee shall rely upon any such statement and request from Lessor and shall
pay such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right or claim against
said sublessee, or, until the Breach has been cured, against Lessor, for any
such rents and other charges so paid by said sublessee to Lessor.

         (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease;
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior Defaults
or Breaches of such sublessor under such sublease.

         (c) Any matter or thing requiring the consent of the sublessor under a
sublease shall also require the consent of Lessor herein.

         (d) No sublessee shall further assign or sublet all or any part of the
Premises without Lessor's prior written consent.

         (e) Lessor shall deliver a copy of any notice of Default or Breach by
Lessee to the sublessee, who shall have the right to cure the Default of Lessee
within the grace period, if any, specified in such notice. The sublessee shall
have a right of reimbursement and offset from and against Lessee for any such
Defaults cured by the sublessee.

13. Default; Breach; Remedies.

   13.1 Default; Breach. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default,

                                     PAGE 6

<PAGE>

and that Lessor may include the cost of such services and costs in said notice
as rent due and payable to cure said Default. A "Default" is defined as a
failure by the Lessee to observe, comply with or perform any of the terms,
covenants, conditions or rules applicable to Lessee under this Lease. A "Breach"
is defined as the occurrence of any one or more of the following Defaults, and,
where a grace period for cure after notice is specified herein, the failure by
Lessee to cure such Default prior to the expiration of the applicable grace
period, shall entitle Lessor to pursue the remedies set forth in Paragraphs
13.2 and/or 13.3:

         (a) The vacating of the Premises without the intention to reoccupy
same, or the abandonment or the Premises.

         (b) Except as expressly otherwise provided in this Lease. (the failure
by Lessee to make any payment of Base Rent or any other monetary payment
required to be made by Lessee hereunder, whether to Lessor or to a third party,
as and when due, the failure by Lessee to provide Lessor with reasonable
evidence of insurance or surety bond required under this Lease, or the failure
of Lessee to fulfill any obligation under this Lease which endangers or
threatens life or property, where such failure continues for a period of three
(3) days following written notice thereof by or on behalf of Lessor to Lessee.

         (c) Except as expressly otherwise provided in this Lease, the failure
by Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with applicable law per
Paragraph 6.3, (ii) the Inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the recission of an unauthorized assignment or
subletting per Paragraph 12.1(b), (iv) a Tenancy Statement per Paragraphs 16 or
37, (v) the subordination or non-subordination of this Lease per Paragraph 30,
(vi) the guaranty of the performance of Lessee's obligations under this Lease if
required under Paragraphs 1.11 and 37, (vii) the execution of any document
requested under Paragraph 42 (easements), or (viii) any other documentation or
information which Lessor may reasonably require of Lessee under the terms of
this Lease, where any such failure continues for a period of ten (10) days
following written notice by or on behalf of Lessor to Lessee.

         (d) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof,
that are to be observed, compiled with or performed by Lessee, other than those
described in subparagraphs (a), (b) or (c), above, where such Default continues
for a period of thirty (30) days after written notice thereof by or on behalf of
Lessor to Lessee; provided, however, that if the nature of Lessee's Default is
such that more than thirty (30) days are reasonably required for its cure, then
it shall not be deemed to be a Breach of this Lease by Lessee if Lessee
commences such cure within said thirty (30) day period and thereafter diligently
prosecutes such cure to completion.

         (e) The occurrence of any of the following events: (i) The making by
lessee of any general arrangement or assignment for  the benefit of creditors;
(ii) Lessee's becoming a "debtor" as defined in 11 U.S.C. section 101 or any
successor statute thereto (unless, in the case of a petition filed against
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment of
a trustee or receiver to take possession of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where possession
is not restored to Lessee within thirty (30) days; or (iv) the attachment,
execution or other judicial seizure of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this subparagraph (e) is contrary to any applicable
law, such provision shall be of no force or effect, and not affect the validity
of the remaining provisions.

         (f) The discovery by Lessor that any financial statement given to
Lessor by Lessee or any Guarantor of Lessee's obligations hereunder was
materially false.

         (g) If the performance of Lessee's obligations under this Lease is
guaranteed: (i) the death of a guarantor, (ii) the termination of a guarantor's
liability with respect to this Lease other than in accordance with the terms of
such guaranty, (iii) a guarantor's becoming insolvent or the subject of a
bankruptcy filing, (iv) a guarantor's refusal to honor the guaranty, or (v) a
guarantor's breach of its guaranty obligation on an anticipatory breach basis,
and Lessee's failure, within sixty (60) days following written notice by or on
behalf of Lessor to Lessee of any such event, to provide Lessor with written
alternative assurance or security, which, when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the guarantors that existed at the time of execution of this Lease.
<PAGE>


    13.2 Remedies. If Lessee falls to perform any affirmative duly or obligation
of Lessee under this Lease, within ten (10) days after written notice to Lessee
(or in case of an emergency, without notice), Lessor may at its option (but
without obligation to do so), perform such duty or obligation on Lessee's
behalf, including but not limited to the obtaining of reasonably required bonds,
insurance policies, or governmental licenses, permits or approvals. The costs
and expenses of any such performance by Lessor shall be due and payable by
Lessee to Lessor upon invoice therefor. If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is drawn, Lessor, at its option,
may require all future payments to be made under this Lease by Lessee to be made
only by cashier's check. In the event of a Breach of this Lease by Lessee, as
defined in Paragraph 13.1, with or without further notice or demand, and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such Breach, Lessor may:

         (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall Immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee: (i) the worth at the time
of the award of the unpaid rent which had been earned at the time of
termination: (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided: and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of the leasing commission paid by Lessor applicable to the unexpired
term of this Lease. The worth at the time of award of the amount referred to in
provision (iii) of the prior sentence shall be computed by discounting such
amount at the discount rate of the Federal Reserve Bank of San Francisco at the
time of award plus one percent (1%). Efforts by Lessor to mitigate damages
caused by Lessee's Default or Breach of this Lease shall not waive Lessor's
right to recover damages under this Paragraph. If termination of this Lease is
obtained through the provisional remedy of unlawful detainer, Lessor shall have
the right to recover in such proceeding the unpaid rent and damages as are
recoverable therein, or Lessor may reserve therein the right to recover all or
any part thereof in a separate suit for such rent and/or damages. If a notice
and grace period required under subparagraphs 13.1(b), (c) or (d) was not
previously given, a notice to pay rent or quit, or to perform or quit, as the
case may be, given to Lessee under any statute authorizing the forfeiture of
leases for unlawful detainer shall also constitute the applicable notice for
grace period purposes required by subparagraphs 13.1(b), (c) or (d). In such
case, the applicable grace period under subparagraphs 13.1(b), (c) or (d) and
under the unlawful detainer statute shall run concurrently after the one such
statutory notice, and the failure of Lessee to cure the Default within the
greater of the two such grace periods shall constitute both an unlawful detainer
and a Breach of this Lease entitling Lessor to the remedies provided for in this
Lease and/or by said statute.

         (b) Continue the Lease and Lessee's right to possession in effect (in
California under California Civil Code Section 1951.4) after Lessee's Breach and
abandonment and recover the rent as it becomes due, provided Lessee has the
right to sublet or assign. subject only to reasonable limitations. See
Paragraphs 12 and 36 for the limitations on assignment and subletting which
limitations Lessee and Lessor agree are reasonable. Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver to
protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

         (c) Pursue any other remedy now or hereafter available to Lessor under
the laws or judicial decisions of the state wherein the Premises are located.

         (d) The expiration or termination of this Lease and/or the termination
of Lessee's right to possession shall not relieve Lessee from liability under
any indemnity provisions of this Lease as to matters occurring or accruing
during the term hereof or by reason of Lessee's occupancy of the Premises.

<PAGE>

    13.3 Inducement Recapture In Event Of Breach. Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions," shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach of this Lease by Lessee, as defined in Paragraph 13.1, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph shall not be deemed a waiver by Lessor of the provisions of this
Paragraph unless specifically so stated in writing by Lessor at the time of such
acceptance.

    13.4 Late Charges. Lessee hereby acknowledges that late payment by Lessee to
Lessor of rent and other sums due hereunder will cause Lessor to incur costs not
contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or trust deed covering the Promises.
Accordingly, If any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within five (5) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to six percent (6%) of such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate or the costs Lessor will Incur by reason of late payment by
Lessee, Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

    13.5 Breach by Lessor. Lessor shall not be deemed in breach of this Lease
unless Lessor falls within a reasonable time to perform an obligation required
to be performed by Lessor. For purposes of this Paragraph 13.5, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and by the holders of any ground lease, mortgage or deed of trust covering the
Premises whose name and address shall have been furnished Lessee in writing for
such purpose, of written notice specifying wherein such obligation of Lessor has
not been performed; provided, however, that if the nature of Lessor's obligation
is such that more than thirty (30) days after such notice are reasonably
required for its performance, then Lessor shall not be in breach of this Lease
if performance is commenced within such thirty (30) day period and thereafter
diligently pursued to completion.

   14. Condemnation. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(all of which are herein called "condemnation"), this Lease shall terminate as
to the part so taken as of the date the condemning authority takes title or
possession, whichever first occurs. If more than ten percent (10%) of the floor
area of the Premises, or more than twenty-five percent (25%) of the land area
not occupied by any building, is taken by condemnation, Lessee may, at Lessee's
option, to be exercised in writing within ten (10) days after Lessor shall have
given Lessee written notice of such taking (or in the absence of such notice,
within ten (10) days after the condemning authority shall have taken possession)
terminate this Lease as of the date the condemning authority takes such
possession, if Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in the same
proportion as the rentable floor area of the Premises taken bears to the total
rentable floor area of the building located on the Premises. No reduction of
Base Rent shall occur if the only portion of the Premises taken is land on which
there is no building. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value or the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessee
shall be entitled to any compensation separately awarded to Lessee for Lessee's
relocation expenses and/or loss of Lessee's Trade Fixtures. In the event that
this Lease is not terminated by reason of such condemnation, Lessor shall to the
extent of its net severance damages received, over and above the legal and other
expenses Incurred by Lessor in the condemnation matter, repair any damage to the
Premises caused by such condemnation, except to the extent that Lessee has been
reimbursed therefor by the condemning authority, Lessee shall be responsible for
the payment of any amount in excess of such net severance damages required to
complete such repair.

15. Broker's Fee.

    15.1 The Brokers named in Paragraph 1.10 are the procuring causes or this
Lease.

   15.2 Upon execution of this Lease by both Parties, Lessor shall pay to said
Brokers jointly, or in such separate shares as they may mutually designate in
writing, a fee as set forth in a separate written agreement between Lessor and
said Brokers (or in the event there is no separate written agreement between
Lessor and said Brokers, the sum of $      N/A      ) for brokerage services
rendered by said Brokers to Lessor in this transaction.

    15.3 Unless Lessor and Brokers have otherwise agreed in writing, Lessor
further agrees that: (a) if Lessee exercises any Option (as defined in Paragraph
39.1) or any Option subsequently granted which is substantially similar to an
Option granted to Lessee in this Lease, or (b) if Lessee acquires any rights to
the Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or (c) if Lessee remains in possession of the Premises,
with the consent of Lessor, after the expiration of the term of this Lease after
having failed to exercise an Option, or (d) if said Brokers are the procuring
cause of any other lease or sale entered into between the Parties pertaining to
the Premises and/or any adjacent property in which Lessor has an interest, or
(e) if Base Rent is increased, whether by agreement or operation of an
escalation clause herein, then as to any of said transactions, Lessor shall pay
said Brokers a fee in accordance with the schedule of sold Brokers in effect at
the time of the execution of this Lease.

    15.4 Any buyer or transferee of Lessor's interest in this Lease, whether
such transfer is by agreement or by operation of law, shall be deemed to have
assumed Lessor's obligation under this Paragraph 15. Each Broker shall be a
third party beneficiary of the provisions of this Paragraph 15 to the extent of
its interest in any commission arising from this Lease and may enforce that
right directly against Lessor and its successors.

    15.5 Lessee and Lessor each represent and warrant to the other that it has
had no dealings with any person, firm, broker or finder (other than the Brokers,
if any named in Paragraph 1.10) in connection with the negotiation of this
Lease and/or the consummation of the transaction contemplated hereby, and that
no broker or other person, firm or entity other than said named Brokers is
entitled to any commission or finder's fee in connection with said transaction.
Lessee and Lessor do each hereby agree to indemnify, protect, defend and hold
the other harmless from and against liability for compensation or charges which
may be claimed by any such unnamed broker, finder or other similar party by
reason of any dealings or actions of the indemnifying Party, including any
costs, expenses, attorneys' fees reasonably incurred with respect thereto.

    15.6 Lessor and Lessee hereby consent to and approve all agency
relationships, including any dual agencies, indicated in Paragraph 1.10.

    16.1 Each Party (as "Responding Party") shall within ten (10) days after
written notice from the other Party (the "Requesting Party") execute,
acknowledge and deliver to the Requesting Party a statement in writing in form
similar to the then most current "Tenancy Statement" form published by the
American Industrial Real Estate Association, plus such additional information,
confirmation and/or statements as may be reasonably requested by the Requesting
Party.

    16.2 If Lessor desires to finance, refinance, or sell the Premises, any part
thereof, or the building of which the Premises are a part, Lessee and all
Guarantors of Lessee's performance hereunder shall deliver to any potential
lender or purchaser designated by Lessor such financial statements of Lessee and
such Guarantors as may be reasonably required by such lender or purchaser,
including but not limited to Lessee's financial statements for the past three
(3) years. All such financial statements shall be received by Lessor and such
lender or purchaser in confidence and shall be used only for the purposes herein
set forth.

    17. Lessor's Liability. The term "Lessor" as used herein shall mean the
owner or owners at the time in question of the fee title to the Premises, or, if
this is a sublease, of the Lessee's interest in the prior lease. In the event
of a transfer of Lessor's title or interest in the Premises or in this Lease,
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in Paragraph 15, upon such transfer or assignment
and delivery of the Security Deposit as aforesaid, the prior Lessor shall be
relieved of all liability with respect to the obligations and/or covenants under
this Lease thereafter to be performed by the Lessor. Subject to the foregoing,
the obligations and/or covenants in this Lease to be performed by the Lessor
shall be binding only upon the Lessor as hereinabove defined.

    18. Severability. The invalidity of any provision of this Lease, as
determined by a court of competent jurisdiction, shall in no way affect the
validity of any other provision hereof.

    19. Interest on Past-Due Obligations. Any monetary payment due Lessor
hereunder, other than late charges, not received by Lessor within thirty (30)
days following the date on which it was due, shall bear interest from the
thirty-first (31st) day after it was due at the rate of 12% per annum, but not
exceeding the maximum rate allowed by law, in addition to the late charge
provided for in Paragraph 13.4.

    20. Time of Essence. Time is of the essence with respect to the performance
of all obligations to be performed or observed by the Parties under this Lease.

    21. Rent Defined. All monetary obligations of Lessee to Lessor under the
terms of this Lease are deemed to be rent.

    22. No Prior or Other Agreements; Broker Disclaimer. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own Investigation as to the nature, quality,
character and financial responsibility of the other Party to this Lease and as
to the nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party.

23. Notices.

    23.1 All notices required or permitted by this Lease shall be in writing and
may be delivered in person (by hand or by messenger or courier service) or may
be sent by regular, certified or registered mail or U.S. Postal Service Express
Mail, with postage prepaid, or by facsimile transmission, and shall be deemed
sufficiently given if served in a manner specified in this Paragraph 23. The
addresses noted adjacent to a Party's signature on this Lease shall be that
Party's address for delivery or mailing of notice purposes. Either Party may by
written notice to the other specify a different address for notice purposes,
except that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for the purpose of mailing or delivering notices to
Lessee. A copy of all notices required or permitted to be given to Lessor
hereunder shall be concurrently transmitted to such party or parties at such
addresses as Lessor may from time to time hereafter designate by written notice
to Lessee.
<PAGE>

    23.2 Any notice sent by registered or certified mail, return receipt
requested, shall be deemed given on the date of delivery shown on the receipt
card, or if no delivery date is shown, the postmark thereon. If sent by regular
mail the notice shall be deemed given forty-eight (48) hours after the same is
addressed as required herein and mailed with postage prepaid. Notices delivered
by United States Express Mail or overnight courier that guarantees next day
delivery shall be deemed given twenty-four (24) hours after delivery of the
same to the United States Postal Service or courier. If any notice is
transmitted by facsimile transmission or similar means, the same shall be deemed
served or delivered upon telephone confirmation of receipt of the transmission
thereof, provided a copy is also delivered via delivery or mall. If notice is
received on a Sunday or legal holiday, it shall be deemed received on the next
business day.

24. Waivers. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or of any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. Regardless of Lessor's
knowledge of a Default or Breach at the time of accepting rent, the acceptance
of rent by Lessor shall not be a waiver of any preceding Default or Breach by
Lessee of any provision hereof, other than the failure of Lessee to pay the
particular rent so accepted. Any payment given Lessor by Lessee may be accepted
by Lessor on account of moneys or damages due Lessor, notwithstanding any
qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

25. Recording. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes. The Party requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

26. No Right To Holdover. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease.

27. Cumulative Remedies. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28. Covenants and Conditions. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

29. Binding Effect; Choice of Law. This Lease shall be binding upon the parties,
their personal representatives, successors and assigns and be governed by the
laws of the State in which the Premises are located. Any litigation between the
Parties hereto concerning this Lease shall be initialed in the county in which
the Promises are located.

30. Subordination; Attornment; Non-Disturbance.

    30.1 Subordination. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "Security Device"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default and
allow such Lender thirty (30) days following receipt of such notice for the cure
of said default before invoking any remedies Lessee may have by reason thereof.
If any Lender shall elect to have this Lease and/or any Option granted hereby
superior to the lien of its Security Device and shall give written notice
thereof to Lessee, this Lease and such Options shall be deemed prior to such
Security Device, notwithstanding the relative dates of the documentation or
recordation thereof.

    30.2 Attornment. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership, (ii) be subject to any offsets or defenses
which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one (1) month's rent.

    30.3 Non-Disturbance. With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving assurance (a "non-disturbance agreement") from the
Lender that Lessee's possession and this Lease, including any options to extend
the term hereof, will not be disturbed so long as Lessee is not in Breach hereof
and attorns to the record owner of the Premises.

    30.4 Self-Executing. The agreements contained in this Paragraph 30 shall be
effective without the execution of any further documents; provided, however,
that, upon written request from Lessor or a Lender in connection with a sale,
financing or refinancing of the Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31. Attorney's Fees. If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) or Broker in any such proceeding, action, or appeal thereon,
shall be entitled to reasonable attorney's fees. Such fees may be awarded in the
same suit or recovered in a separate suit, whether or not such action or
proceeding is pursued to decision or judgment. The term, "Prevailing Party"
shall include, without limitation, a Party or Broker who substantially obtains
or defeats the relief sought, as the case may be, whether by compromise,
settlement, judgment, or the abandonment by the other Party or Broker of its
claim or defense. The attorney's fee award shall not be computed in accordance
with any court fee schedule, but shall be such as to fully reimburse all
attorney's fees reasonably incurred. Lessor shall be entitled to attorney's
fees, costs and expenses incurred in the preparation and service of notices of
Default and consultations in connection therewith, whether or not a legal action
is subsequently commenced in connection with such Default or resulting Breach.

32. Lessor's Access; Showing Premises; Repairs. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonable times for the purpose of showing the same to
prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the building of which
they are a part, as Lessor may reasonably deem necessary. Lessor may at any time
place on or about the Premises or building any ordinary "For Sale" signs and
Lessor may at any time during the last one hundred twenty (120) days of the term
hereof place on or about the Premises any ordinary "For Lease" signs. All such
activities of Lessor shall be without abatement of rent or liability to Lessee.
<PAGE>

33. Auctions. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34. Signs. Lessee shall not place any sign upon the Premises, except that Lessee
may, with Lessor's prior written consent, install (but not on the roof) such
signs as are reasonably required to advertise Lessee's own business. The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations). Unless otherwise expressly agreed herein,
Lessor reserves all rights to the use of the roof and the right to install, and
all revenues from the installation of, such advertising signs on the Premises,
including the roof, as do not unreasonably Interfere with the conduct of
Lessee's business.

35. Termination; Merger. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises: provided, however, Lessor shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of any
existing subtenancies. Lessor's failure within ten (10) days following any such
event to make a written election to the contrary by written notice to the holder
of any such lesser interest, shall constitute Lessor's election to have such
event constitute the termination of such Interest.

36. Consents.
    (a) Except for Paragraph 33 hereof (Auctions) or as otherwise provided
herein, wherever in this Lease the consent of a Party is required to an act by
or for the other Party, such consent shall not be unreasonably withheld or
delayed. Lessor's actual reasonable costs and expenses (including but not
limited to architects', attorneys', engineers' or other consultants' fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment, a subletting or the presence or use of a
Hazardous Substance, practice or storage tank, shall be paid by Lessee to Lessor
upon receipt of an invoice and supporting documentation therefor. Subject to
Paragraph 12.2(e) (applicable to assignment or subletting), Lessor may, as a
condition to considering any such request by Lessee, require that Lessee deposit
with Lessor an amount of money (in addition to the Security Deposit held under
Paragraph 5) reasonably calculated by Lessor to represent the cost Lessor will
incur in considering and responding to Lessee's request, Except as otherwise
provided, any unused portion of said deposit shall be refunded to Lessee without
interest. Lessor's consent to any act, assignment of this Lease or subletting of
the Premises by Lessee shall not constitute an acknowledgement that no Default
or Breach by Lessee of this Lease exists, nor shall such consent be deemed a
waiver of any then existing Default or Breach, except as may be otherwise
specifically stated in writing by Lessor at the time of such consent.

    (b) All conditions to Lessor's consent authorized by this Lease are
acknowledged by Lessee as being reasonable. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the imposition by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular mailer for which consent is being
given.

37. Guarantor.

    37.1 If there are to be any Guarantors of this Lease per Paragraph 1.11,
the form of the guaranty to be executed by each such Guarantor shall be in the
form most recently published by the American Industrial Real Estate Association,
and each said Guarantor shall have the same obligations as Lessee under this
Lease, including but not limited to the obligation to provide the Tenancy
Statement and information called for by Paragraph 16.

    37.2 It shall constitute a Default of the Lessee under this Lease if any
such Guarantor fails or refuses, upon reasonable request by Lessor to give: (a)
evidence of the due execution of the guaranty called for by this Lease,
including the authority of the Guarantor (and of the party signing on
Guarantor's behalf) to obligate such Guarantor on said guaranty, and including
in the case of a corporate Guarantor, a certified copy of a resolution of its
board of directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signature of the Persons authorized to
sign on its behalf, (b) current financial statements of Guarantor as may from
time to time be requested by Lessor, (c) a Tenancy Statement, or (d) written
confirmation that the guaranty is still in effect.

assignable, either as a part of an assignment of this Lease or separately or

and be of no further force or effect, notwithstanding Lessee's due and timely
exercise of the Option, if, after such exercise and during the term of this

                                 Addendum No. I

This is an addendum ("Addendum") to that certain Standard Industrial/Commercial
Single-Tenant Lease-Gross dated May 5, 1997 by and between YHS (USA), Inc., a
California Corporation ("Lessor") and Impax Pharmaceuticals, Inc., a California
Corporation ("Lessee"). Notwithstanding any other terms, conditions or
provisions of the Lease to the contrary, the terms, conditions, and provisions
of this Addendum shall control. For good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto hereby
agree to amend the Lease as follows:

49.     Rental Schedule:
        Lessee shall pay to Lessor as base rent for the Premises, without any
        offset or deduction, except as set forth in Section 4.1 of this Lease,
        on the first day of each month of the term hereof, monthly payments in
        advance as follows;

        July 1, 1997 through December 31, 1999 .....................  $12,879.36
        January 1, 2000 through June 30, 2002 ......................  $13,777.92

50.     Option to Extend:
        Lessee shall have the personal non-transferable right to extend the term
        of the Lease for one (1) term of three (3) years at a flat rate of
        $14,676.48 per month gross. Provided that the Lease is in full force and
        effect and that Lessee has not been in material default of the Lease at
        the time of Lessee's election to extend the commencement of the
        extension period, Lessee may exercise the option by providing Lessor
        written notice not less than sixty (60) days prior to the expiration of
        the then current term. Lessee's election shall be irrevocable.

51.     Basic Improvements:
        Lessor and Lessee agree that the items set forth in this Section 51 need
        to be made in order to make the Premises suitable for Lessee's occupancy
        thereof. Except as set forth herein, said below-itemized list of
        improvements is complete and Lessor shall not be required to provide or
        pay for any additional items.

        Lessor shall, at Lessor's sole cost and expense, deliver the Premises
        with all HVAC, mechanical, and plumbing systems to be in good working
        order.

        Lessee shall cause the following work to be performed on the Premises:

                                       1

<PAGE>

        51.1    Repair roof leak in the conference room/kitchen area.

        51.2    Replace carpets in the office area and open area.

        51.3    Remove tile in the kitchen and open space area, seal the
                underlying concrete against future leakage where necessary, and
                replace flooring in the kitchen and open area.

        51.4    Paint all office walls.

        Lessee shall submit to Lessor documentation evidencing its expenditures
in connection with the foregoing improvements, and Lessor shall, within thirty
(30) days following receipt of such documentation, reimburse Lessee for its
expenditures in an amount not to exceed $6,115 (the "Reimbursement Amount").
Lessee and Lessor have received an estimate that the roof repair can be
accomplished for $1,050. In the event, that it is subsequently determined that
the roof leak cannot be repaired for $1,050, then (i) if the parties can
mutually agree upon an increased allocation for the roof repair, Lessee will
cause the roof repair to be performed and the Reimbursement Amount shall be
increased by the mutually agreed upon increased allocation; or (ii) Lessor shall
assume the obligation of such repair, and Lessee's right to reimbursement
hereunder shall be reduced to $5,065. Nothing herein shall alter, in any manner
whatsoever, Lessor's obligations to maintain the roof and structural aspects of
the Premises pursuant to Section 7.2 hereof. Moreover, Lessee makes no warranty
as to any roof repair performed pursuant to this Section 51.

52.     Lessee Improvements:
        Lessor acknowledges that Lessee will be making substantial improvements
        within the building including, but not limited to, rehabilitation of the
        existing office area, as well as adding additional office space, wet
        labs and pharmaceutical manufacturing areas. Said improvements shall be
        done at Lessee's expense. Such improvements will require punching one or
        more holes in the roofs and/or walls of the Premises. Lessee shall
        submit its plans to Lessor for Lessor's prior approval, along with a
        certification from a structural engineer, that the proposed holes in the
        roof or walls will not weaken the structural integrity of the Premises.
        Subject to the submission of the foregoing, Lessor shall not
        unreasonably withhold approval of the Premises. In the event that this
        Lease terminates and Lessee does not purchase the Premises, then Lessee
        shall fill the holes and provide an additional certification from a
        structural engineer that the holes, as filled, do not weaken the
        structural integrity of the Premises.

        calendar year 1997, and the structural integrity of the Premises,
        including, without limitation, the foundation, walls and roof. Lessee
        shall be responsible for any increases over the base year expenses.

                set-off the reasonable costs incurred in connection with such
                repair and restoration against future rent."

                or restoration, give written notice to Lessor and to any Lenders

        "any" is inserted.

80.     In the next to last line of Section 13.1(g), beginning with the "equals

        million dollars ($1,000,000),".

86.     Sale of the Premises. In the event Lessor is considering the sale of the
        Premises and is considering placing the Premises on the market for sale,
        then Lessor shall first given written notice of such intention to
        Lessee, and Lessor and Lessee shall negotiate in good faith the terms
        and conditions of the sale of the Premises to Lessee. If Lessor and
        Lessee cannot mutually agree upon the terms and conditions of sale of
        the Premises to Lessee within thirty (30) days following notice of
        Lessor's intent to market the Premises for sale, then Lessor shall be
        entitled to make the Premises publicly available for sale.

87.     Contingency Regarding Inspection of Physical Condition of the Premises.
        Prior to the commencement date of the Lease, Lessee and its agents,
        shall be entitled to enter the Premises and to conduct or cause to be
        conducted thereon, such physical inspections and engineering, soils or
        other tests and procedures, including without limitation an
        environmental audit of the Premises, as Lessee deems appropriate. Lessee
        hereby indemnifies Lessor against damage to the Premises or to persons
        on the Premises incurred as a direct result of any such inspections,
        tests or procedures by Lessee.

        Lessor acknowledges that Lessee is currently conducting a Phase II
        environmental study with respect to the Premises, and Lessor hereby
        extends Lessee's time to accept or reject the physical condition of the
        Premises, solely as it relates to such Phase 11 environmental study,
        until July 11, 1997. Lessee agrees that its approval shall not be
        unreasonably withheld. In the event that Lessee does not notify Lessor
        in writing by the close of business on July 11, 1997, then Lessee shall
        be deemed to have approved the physical condition of the Premises. In
        the event Lessee disapproves of the physical condition of the Premises,
        and at the sole discretion of Lessee, (i) this Lease will immediately
        terminate and be of no further force and effect; and (ii) Lessor shall
        return Lessee's Security Deposit, subject to Section 5 hereof, and shall
        reimburse Lessee for Lessee's pro rata portion of unused Base Rent.
        Alternatively, Lessee and Lessor may mutually agree upon specific terms
        and conditions whereby Lessor will, at Lessor's sole expense, promptly
        perform appropriate environmental remediation sufficient to remove any
        environmental contamination located on the Premises and

                                        9

<PAGE>

        to bring the Premises in compliance with all applicable laws and
        regulations. Upon such mutual agreement, and subject to Lessor's timely
        performance of all terms and conditions specified therein, this Lease
        will otherwise continue in full force and effect,

Agreement or the Escrow Agreement, and all actions of the Seller Stockholders,
whether pursuant to the Merger Agreement or the Escrow Agreement, must be taken
solely by the Seller Stockholders' Agent.

                  (b) Buyer shall have no liability of any kind to any Seller
Stockholder as a result of or arising out of any action taken or not taken by
the Seller Stockholders' Agent at any time under the Merger Agreement or the
Escrow Agreement and each Seller Stockholder hereby releases Buyer from any such
liability. Buyer may conclusively rely, without any obligation of investigation
or inquiry of any kind, on any action taken by the Seller Stockholders' Agent as
having been fully authorized and approved by all necessary action by each Seller
Stockholder (except such Seller Stockholders, if any, as shall have perfected
their dissenter rights under applicable law).

         5. Claims Against Escrow Fund.

                  (a) Subject to the terms and conditions of this Agreement, the
Escrow Fund shall be applied to indemnify and hold harmless the Buyer
Indemnitees against and in respect of Losses as set forth in a Claim Certificate
(as defined below) duly delivered to the Escrow Agent and the Seller
Stockholders prior to the Termination Date. If the Buyer Indemnitees shall
suffer or incur Losses as to which indemnification is provided for under the
indemnification provisions of the Merger Agreement, it or they shall deliver to
the Escrow Agent and the Seller Stockholders a certificate (a "Claim
Certificate"), which shall be signed by the President, Chief Executive Officer
or Chief Operating Officer of GLOBAL to the effect that Buyer Indemnitees have
suffered or incurred Losses in the amount specified in such Claim Certificate
and setting forth the basis for such Losses. Upon receipt of any such Claim
Certificate and subject to Section 5(b), the Escrow Agent shall, as soon as
practicable (but not earlier than twelve (12) business days after the delivery
to the Escrow Agent of such Claim Certificate) pay to Buyer Indemnitees an
amount equal to the amount of Losses so suffered or incurred by Buyer
Indemnitees as set forth in such Claim Certificate out of the Escrow Fund.
Whenever the Escrow Agent is required to make a payment out of the Escrow Fund
hereunder, the Escrow Agent shall withdraw from the Escrow Fund in accordance
with a written instruction of GLOBAL (which written instruction shall include
a computation of the value of such shares of Buyer Stock and Other Property
calculated in accordance with Section 9.04(c) of the Merger Agreement and this
Escrow Agreement, and shall include a calculation which confirms that the
payment shall be made for the accounts of the Seller Stockholders pro rata in
accordance with the ratio of the original deposits of Buyer Stock which comprise
the Escrow Fund), (i) first, any cash comprising the Escrow Fund, (ii) second,
to the extent that there is insufficient cash to pay the Losses, shares of Buyer
Stock and (iii) third to the extent there is an insufficient number of shares of
Buyer Stock in the Escrow Fund to pay the Losses, any other property delivered
to, and remaining in, the Escrow Fund in accordance with Section 8 hereof
("Other Property"). The Escrow Agent shall transfer, deliver and assign to Buyer
Indemnitees such cash, number of shares of Buyer Stock (rounded to the next
highest whole share) held in the Escrow Fund and/or Other Property which shall
be indicated within the written instrument of Buyer Indemnitees referred to
hereinabove and required to be delivered to the Escrow Agent. Shares of Buyer
Stock shall be valued in accordance with the terms of Section 9.04(c) of the
Merger Agreement and Other Property, if any,


                                       -4-

<PAGE>



shall be valued in good faith by the Board of Directors of GLOBAL. The
delivery by the Escrow Agent to Buyer Indemnitees of the shares of Buyer Stock
determined by GLOBAL's computation of their value as stated above and stated
in the written instruction to the Escrow Agent shall be effected by surrender to
GLOBAL, or its transfer agent, of the Escrow Certificates then in its
possession, and GLOBAL, or its transfer agent, shall promptly issue to the
Escrow Agent a new stock certificate registered in its name for the number of
shares of Buyer Stock then remaining in the Escrow Fund as reduced by the number
of shares surrendered to Buyer Indemnitees.

                  (b) Unless, within ten (10) business days after delivery to
the Seller Stockholders of any Claim Certificate, Seller Stockholders who
beneficially own a majority in interest of the Escrowed Stock then held in the
Escrow Fund (the "Majority Owners") give written notice to GLOBAL and the
Escrow Agent that they question the accuracy of, or matters included in, such
Claim Certificate, such Claim Certificate shall constitute full authority to the
Escrow Agent to take the action provided for in the preceding paragraph and
shall be conclusive on all parties hereto. If the Majority Owners give notice
questioning the accuracy of, or matters included in, such Claim Certificate, the
Escrow Agent shall not assign to Buyer Indemnitees any Escrowed Stock or make
any indemnification payment to Buyer Indemnitees pursuant to this Section 5
until (i) it receives the written consent of the Majority Owners or (ii) there
is a Final Determination with respect to the dispute. After notice by the
Majority Owners of disagreement with the accuracy of, or matters included in, a
Claim Certificate, either Buyer Indemnitees (on the one hand) or the Seller
Stockholders, acting jointly but not severally (on the other hand), may seek a
declaratory judgment from any court of competent jurisdiction to resolve the
disagreement. The party against whom such declaratory judgment is actually
rendered shall reimburse the other party thereto for the reasonable expenses
incurred by it in the defense, prosecution, or investigation of such claim.

                  (c) Notwithstanding anything herein to the contrary, no
payments shall be made out of the Escrow Fund for indemnity of Losses until such
Losses exceed the Base Amount, at which time, all Losses theretofore accrued
shall be paid.

                  (d) If any dispute arises as to any matter arising under this
Escrow Agreement or there arises any uncertainty as to the meaning or
applicability of any of the provisions hereof, or as to the Escrow Agent's
duties, rights or responsibilities hereunder, the Escrow Agent may, at its
option or at any time thereafter deposit the Escrowed Stock then being held by
it in escrow into a court having appropriate jurisdiction, and the Escrow Agent
shall thereby be discharged and relieved of all liability hereunder.

         6. Termination. The Escrow Fund shall terminate on the Termination
Date, and upon written notice from GLOBAL and the Majority Owners to the
Escrow Agent. Any shares or other assets then held in the Escrow Fund shall be
distributed upon termination by the Escrow Agent in accordance with the
provisions of Section 7 hereof. Notwithstanding the foregoing, if on or before
the Termination Date any Buyer Indemnitees have (a) duly delivered a Claim
Certificate with respect to a claim which has not been satisfied pursuant to
this Agreement or (b) delivered to the Escrow Agent and the Seller Stockholders
written notice of the occurrence of an event which


                                       -5-

<PAGE>



constitutes a breach of any representation, warranty or agreement made by the
Seller Stockholders in the Merger Agreement and may give rise to a claim for
indemnification under the Merger Agreement and this Agreement, and if such Buyer
Indemnitees have delivered to the Escrow Agent a good faith written estimate of
the maximum potential amount of Losses resulting from such claim or potential
claim, the Escrow Fund shall not terminate with respect to such claims until all
such claims have been fully satisfied or resolved or a Final Determination has
been rendered with respect thereto. Until such termination, the Escrow Agent
shall retain in the Escrow Fund that amount of Escrowed Stock as instructed in
writing by the Buyer Indemnitees and having a value allocated and determined in
accordance with the indemnification provisions of the Merger Agreement and this
Agreement, which Escrowed Stock shall equal 100% of the Buyer Indemnitees'
estimate of Losses resulting from all then outstanding claims. In the event that
the value of the shares of Buyer Stock and other assets, if any, then remaining
in the Escrow Fund is less than 100% of the Buyer Indemnitees' estimate of
Losses resulting from all then outstanding claims, then GLOBAL shall instruct
the Escrow Agent in writing to retain all remaining assets in the Escrow Fund.
Promptly after the Termination Date, any shares or other assets in the Escrow
Fund having a value in excess of that required to be retained in the Escrow Fund
pursuant to the foregoing shall be distributed to the Seller Stockholders in
accordance with Section 7 hereof and shall no longer be subject to this
Agreement.

         7. Distribution of the Escrowed Stock. Upon the termination of the
Escrow Fund pursuant to Section 6 hereof, and subject to the terms of such
Section, the Escrow Agent shall, within 10 days of such Termination Date,
distribute to each of the Seller Stockholders at their last known addresses
appearing on the records of the Escrow Agent, the amount of Escrowed Stock to be
distributed to the Seller Stockholders pursuant to Section 6 hereof in the same
proportion, and of the same class, as shares of Buyer Stock were issued to any
such Seller Stockholders in the Merger. Any delivery of shares of Buyer Stock
shall be of full shares, and the Escrow Agent shall, upon instructions received
from the Majority Owners, make such adjustments for fractional share interests
as the Majority Owners in their sole discretion deem appropriate.

         8. Delivery and Deposit of Additional Shares or Dividends. Any shares
of Buyer Stock or other equity securities issued or distributed by Buyer
(including shares issued upon a stock split) ("New Shares") in respect of Buyer
Stock in the Escrow which have not been released from the Escrow shall be added
to the Escrow and become a part thereof. New Shares issued in respect of Buyer
Stock which have been released from the Escrow shall not be added to the Escrow,
but shall be distributed to the holders thereof. When and if cash dividends on
Buyer Stock in the Escrow shall be declared and paid, they shall not be added to
the Escrow, but shall be paid to those on whose behalf such Buyer Stock is held
who, at the Effective Time, held Seller Stock.

         9. Voting of Shares and Reports. Each Seller Stockholder shall have
voting rights with respect to the shares of Buyer Stock contributed to the
Escrow on behalf of such Seller Stockholder (and on any voting securities added
to the Escrow in respect of such shares of Buyer Stock) so long as such shares
of Buyer Stock or other voting securities are held in the Escrow. As the record
holder of such shares, the Escrow Agent shall vote such shares in accordance
with the instructions of the


                                       -6-

<PAGE>



Seller Stockholders having the beneficial interest therein and shall promptly
deliver copies of all proxy solicitation materials to such Seller Stockholders.
The Escrow Agent shall not vote any shares of Escrowed Stock as to which no
voting instructions have been given.

         10. Notice. Unless written designation of a different address is filed
with each of the other parties hereto, all notices and Claim Certificates
required to be given under this Agreement shall be deemed to have been properly
given if in writing and delivered or mailed by registered or certified mail,
postage prepaid. Mailed notices and Claim Certificates shall be deemed given
when duly mailed and addressed as follows:

(including reasonable attorneys' fees) which may be incurred by it as a result
of its involvement in any litigation arising from performance of its duties

conclusively rely upon and shall be protected, indemnified and held harmless by
GLOBAL and the Seller Stockholders, jointly and severally, in acting upon the

either of them or of counsel to either of them with respect to any matter
relating to its actions as Escrow Agent hereunder, and the Escrow Agent shall be
entitled to request that further instructions be given by such persons or to
request that instructions be given in writing.

to receive all the Escrow Fund.

         16. Confirmation of Escrow Agent's Appointment. GLOBAL and the Seller
