         In consideration of the Recital and of the mutual promises set forth in
this Agreement, the Company and the Executive agree as set forth below.

         1.       EMPLOYMENT.

         (A) EMPLOYMENT AND TERM. The Company agrees to employ the Executive and
the Executive agrees to be employed by the Company, on the terms and conditions
of this Agreement, for a period commencing on the Effective Date and expiring on
the fifth anniversary of the Effective Date (the "INITIAL TERM"). The term of

"RENEWAL TERM"), on the fifth anniversary of the Effective Date and on each
subsequent anniversary of the Effective Date unless at least two years and 90
days prior to any such anniversary, the Executive shall have delivered to the
Company a written notice stating that the term of the Agreement will not be
extended. For purposes of this Agreement, the word "TERM" means the Initial Term
and all Renewal Terms.

         (B) DUTIES. The Executive shall serve as the President and Chief
Executive Officer of Zenith Goldline Pharmaceuticals, Inc. ("ZENITH GOLDLINE")
and shall have powers and authority superior to any other officer or employee of
Zenith Goldline. In that capacity, he shall be responsible for the operation of
Zenith Goldline's activities globally, which shall include the coordination of
Zenith Goldline's activities with those of the Company's affiliates in various
parts of the world, and shall have duties commensurate with his position. The
Executive shall also serve as a Senior Vice President of the Company and in this
capacity shall have such powers and authority as may be given to him from time
to time by the Board of Directors of the Company or a committee thereof (the
"BOARD OF DIRECTORS"). The Executive shall report to and be subject to the
supervision and direction of the Chief Operating Officer, the Chief Executive
Officer, and the Board of Directors. The Executive shall devote his full
business time and energies to the business and affairs of the Company and shall
use his best efforts, skills and abilities to promote the interests of the
Company and to diligently and competently perform the duties of his position.
The Executive shall have the right to (i) serve on civic or charitable boards or
committees and, with the consent of the Board of Directors, serve on corporate
boards, (ii) deliver lectures, fulfill speaking engagements, or teach at
educational institutions, and (iii) manage personal investments; provided that
such activities do not unreasonably interfere with the Executive's duties to the
Company under this Agreement. 

<PAGE>

         (C) PLACE OF PERFORMANCE. The Executive will perform his duties from
Zenith Goldline's principal place of business, which is currently located in Ft.
Lauderdale, Florida, except for travel reasonably necessary in connection with
the Company's and Zenith Goldline's business. The Executive acknowledges that
the Company may cause Zenith Goldline's principal place of business to be moved
to Miami, Florida.

         (D) WORKING FACILITIES. The Company shall provide the Executive with an
office, a secretary, a portable phone, a portable personal computer, a home
facsimile, and such other customary facilities and equipment as are necessary
for the performance of his duties, all of which Executive acknowledges are and
shall remain the property of the Company.

         2.       COMPENSATION.

         (A) SIGNING BONUS. Within two business days after the Effective Date,
the Company shall pay to the Executive a cash signing bonus in the amount of
$200,000.

         (B) INITIAL STOCK OPTION GRANT. The Company shall grant to the
Executive, in accordance with the terms of the Company's 1994 Stock Option Plan
(the "PLAN"), nonqualified options (the "INITIAL STOCK OPTIONS") to purchase
250,000 shares of the common stock of the Company (the "COMMON STOCK"). The
exercise price of the Initial Stock Options shall be equal to the closing price
of the Common Stock, as reported in THE WALL STREET JOURNAL, on the Effective
Date. The Initial Stock Options shall have a term of ten years. The Initial
Stock Options shall vest 25% on the Effective Date and 25% on each of the first
three anniversary dates of the Effective Date; provided that the Initial Stock
Options shall vest and become immediately exercisable upon a termination of
Executive's employment pursuant to Sections 4(a) or 4(b). The Company agrees to
take all action reasonably requested by the Executive to permit the Executive to
take advantage of the "cashless" exercise feature of Section 4(d) of the Plan to
exercise the Initial Stock Options. Immediately upon the exercise of the Initial
Stock Options in accordance with the Plan, the Executive shall be deemed to be
the owner of the Common Stock into which the Initial Stock Options were
exercisable. In case at any time or from time to time the holders of Common
Stock become entitled to receive, without payment therefor, other or additional
stock or other securities or property of the Company by way of a spin-off,
special dividend and/or liquidation distribution (other than a regular cash
dividend), the Board of Directors shall consider in good faith a fair and
equitable adjustment to the exercise price or other terms of the Initial Stock
Options. The Initial Stock Options will not be affected by any amendment to
Section 13(c) of the Plan.

         (C) BASE SALARY. The Executive will be paid a base salary at the annual
rate of not less than $575,000 (the "BASE SALARY"). In addition, the Company
shall pay to the Executive annually the sum of $38,500 as additional cash
compensation. The Base Salary and the additional cash compensation shall be paid
in installments consistent with the Company's normal payroll policies. The
Company shall review the Base Salary six months after the Effective Date and
annually thereafter for merit increases, which shall be made subject to and at
the discretion of the Board of Directors. Once increased, the Base Salary shall
not thereafter be decreased.

         (D) ANNUAL BONUS. The Executive shall be entitled to receive an annual
cash bonus in an amount up to 100% of the Base Salary based on the Executive's
performance during the applicable year. The amount of the bonus payable in any
year shall be determined by reference to the profitability of Zenith Goldline
and such other measures as the Company and the Executive may agree. The terms
and conditions relating to the payment and amount of the bonus shall be
negotiated in good faith by the Company and the Executive. The Executive
acknowledges that the Company requires that the bonus satisfy the requirements
for performance-based compensation under Section 162(m) of the Internal Revenue
Code of 1986, as amended (the "CODE"). 

<PAGE>

         (E) SUBSEQUENT STOCK OPTIONS. The Executive shall be entitled to
receive stock options and such other long term compensation as may be determined
by the Board of Directors from time to time in its discretion. In making any
determinations concerning the award of stock options to the Executive, the Board
of Directors will apply the same criteria as it applies in making awards to the
other key executives of the Company, and its determinations will not be affected
by the bonus arrangement described in Section 2(d).

Company to other key executives of the Company based in the United States. The

adversely affect the Company.

all welfare benefit plans, practices, policies and programs, if any, generally
made available by the Company to other key executives of the Company based in

this Agreement for Good Reason. For purposes of this Agreement, the term "GOOD
REASON" means:

                  (i) the assignment to the Executive of any duties inconsistent
         in any respect with the Executive's position (including status,
         offices, titles and reporting requirements), authority, duties or

                  (iv) any termination by the Company of the Executive's
         employment otherwise than as expressly permitted by this Agreement;

                  (v) any failure by the Company to comply with and satisfy the
         penultimate sentence of Section 9(c)(iii); or

                  (vi) any termination by the Executive for any reason during
         the three-month period following the effective date of any Change in
         Control (as defined in Section 5).

For purposes of this Section, any good faith determination of Good Reason made
by the Executive shall be conclusive.

         (C) TERMINATION FOR CAUSE. Notwithstanding any other provision of this
Agreement, this Agreement may be terminated by the Company for Cause. For
purposes of this Agreement, the word "CAUSE" means: (i) an act or acts of
personal dishonesty taken by the Executive and intended to result in the direct
or indirect personal enrichment of the Executive at the expense of the Company
(except that disputes regarding expense reimbursement shall not be subject to
this clause and shall instead be resolved in good faith by the Board of
Directors and the Executive), (ii) subject to the following sentences, violation
by the Executive of his material obligations or representations under this
Agreement which are demonstrably willful and deliberate and which are not
remedied within 30 days after written notice to the Executive, or (iii) the
conviction of the Executive of any criminal act which is a felony. Upon a
determination by the Company that cause exists under clause (ii) of the
preceding sentence, the Company shall cause a special meeting of the Board of
Directors to be called and held at a time mutually convenient to the Board of
Directors and the Executive, but in no event later than 10 business days after
the Executive's receipt of the notice contemplated in clause (ii). The Executive
shall have the right to appear at such special meeting with legal counsel of his
choosing to refute any determination of Cause specified in such notice, and any
termination of this Agreement by reason of such Cause determination shall not be
effective until the Executive is afforded such opportunity to appear before the
Board of Directors. Any notice of termination for Cause pursuant to clause (i)
or (iii) of the second sentence of this Section shall be made in writing to the
Executive, which notice shall set forth in detail all acts or omissions upon
which the Company is relying for such termination. Upon any termination pursuant
to this Section, the Executive shall be entitled to be paid his Base Salary to
the date of termination and the Company shall have no further liability under
this Agreement to the Executive (other than for reimbursement of business
expenses incurred prior to the termination date, in accordance with Section
3(a)).

 <PAGE>

         (D) DEATH. This Agreement shall automatically terminate upon the death
of the Executive. If this Agreement is terminated pursuant to this Section, the
Company shall pay to the Executive's estate (i) Base Salary through the
termination date, and (ii) an amount in cash equal to six months of the Base
Salary as of the date of termination.

         (E) DISABILITY. The Company, by written notice to the Executive, shall
at all times have the right to terminate this Agreement if the Executive shall,
as the result of mental or physical incapacity, illness or disability, fail to
perform his duties and responsibilities provided for herein for a period of more
than 180 consecutive days. Upon any termination pursuant to this Section 4(e),
the Executive shall be entitled to be paid his Base Salary to the date of
termination and the Company shall have no further liability hereunder (other
than for reimbursement of business expenses incurred prior to the termination
date, in accordance with Section 3(a)).

         5. CHANGE IN CONTROL. For purposes of this Agreement, a "CHANGE IN
CONTROL" means any one of the following events:

         (a) The acquisition (other than by or from the Company), at any time
after the date hereof, by any person, entity or "group", within the meaning of
Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934 (the
"EXCHANGE ACT"), of beneficial ownership (within the meaning of Rule 13d-3
promulgated under the Exchange Act) of 50% or more of either the then
outstanding shares of Common Stock or the combined voting power of the Company's
then outstanding voting securities entitled to vote generally in the election of
directors; or

         (b) All or any of the individuals who, as of the Effective Date,
constitute the full Board of Directors (the "INCUMBENT BOARD") cease for any
reason to constitute at least a majority of the Board, provided that any person
becoming a director subsequent to the Effective Date whose election, or
nomination for election by the Company's shareholders, was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board (other
than an election or nomination of an individual whose initial assumption of
office is in connection with an actual or threatened election contest relating
to the election of the directors of the Company, as such terms are used in Rule
14a-11 of Regulation 14A promulgated under the Exchange Act) shall be, for
purposes of this Agreement, considered as though such person were a member of
the Incumbent Board; or

         (c) Approval by the shareholders of the Company of (i) a
reorganization, merger or consolidation with respect to which persons who were
the shareholders of the Company immediately prior to such reorganization, merger
or consolidation do not, immediately thereafter, own more than 50% of the
combined voting power entitled to vote generally in the election of directors of
the reorganized, merged or consolidated company's then outstanding voting
securities, (ii) a liquidation or dissolution of the Company, or (iii) the sale
of all or substantially all of the assets of the Company, unless the approved
reorganization, merger, consolidation, liquidation, dissolution or sale is
subsequently abandoned.

Notwithstanding anything contained in this Section 5 to the contrary, any
transaction in which Zenith Goldline becomes a separate company the shares of
which are publicly traded on a stock exchange or on the National Association of
Securities Dealers' Automated Quotation system (by way of a spin-off, split-off,
public offering, merger, consolidation or otherwise) shall not be deemed a
change in control under this Agreement; provided that, concurrent with such


<PAGE>

transaction, this Agreement is assumed by Zenith Goldline and the Executive is
appointed the Chief Executive Officer of Zenith Goldline.

         6.       RESTRICTIVE COVENANTS.

         (A) NONDISCLOSURE. On the Effective Date, the Executive will execute
the Company's standard form of Confidentiality Agreement, a copy of which is
attached hereto as Exhibit A.

         (B) NONSOLICITATION OF EMPLOYEES. While employed by the Company and for
a period of two years thereafter, Executive shall not directly or indirectly,
for himself or for any other person, firm, corporation, partnership, association
or other entity, attempt to employ or enter into any contractual arrangement
with any employee or former employee of the Company, unless such employee or
former employee has not been employed by the Company for a period in excess of
one year.

         (C) INJUNCTION. It is recognized and hereby acknowledged by the parties
hereto that a breach by the Executive of any of the covenants contained in
Section 6(a) or 6(b) will cause irreparable harm and damage to the Company, the
monetary amount of which may be virtually impossible to ascertain. As a result,
the Executive recognizes and hereby acknowledges that the Company shall be
entitled to an injunction from any court of competent jurisdiction enjoining and
restraining any violation of any or all of the covenants contained in such
Section by the Executive or any of his affiliates, associates, partners or
agents, either directly or indirectly, and that such right to injunction shall
be cumulative and in addition to whatever other remedies the Company may
possess.

         7.       CONFLICTS WITH EXISTING AGREEMENTS; COMPANY POLICIES.

         (a) The Executive represents and warrants that attached hereto as
Exhibit B is a true and complete copy of all contracts (or, if oral, an accurate
written description thereof) to which he is a party, or bound by, which in the
future may have a possibility of adversely affecting the business of the Company
or the performance by the Executive of his duties under this Agreement,
including but not limited to contracts related to previous employment containing
confidentiality or noncompete covenants. The Company acknowledges that it has
reviewed Exhibit B.

         (b) The Executive acknowledges that he will be subject to and required
to abide by the policies and procedures of the Company applicable to senior
executives as in effect from time to time, and that he will be required to
execute and abide by the Company's Code of Conduct, as in effect from time to
time.

         8. VISAS. The Company will sponsor the Executive for a non-immigrant
visa to permit the Executive to live and work in the United States. Following
the receipt of such visa, the Company agrees to sponsor the Executive for an
immigrant visa ("green card"). The Company will pay all legal and other expenses
related to obtaining the non-immigrant visa and immigrant visa. The Executive
agrees to take all actions necessary and appropriate to obtain the non-immigrant
visa and immigrant visa and shall fully cooperate with the Company in good faith
to obtain such visas. In the event that a visa is not granted to the Executive,
and all applicable appeals have been exhausted, this Agreement shall be deemed
to have been terminated pursuant to Section 4(a) and the Executive will be
entitled to receive the payments and the benefits provided in that Section;
provided that if the Executive's representation in the last sentence of this

<PAGE>

Section is not true, then, notwithstanding the provisions of Section 4(a), the
Company shall only be required to pay to the Executive in a cash lump sum an
amount equal to his then Base Salary and to continue to provide benefits to the
Executive pursuant to Section 3(c) for a period of one year; and provided
further, that, if the Company requests that the Executive serve as the chief
executive officer of its Canadian-based generic pharmaceutical business, then
the Executive shall assume such position and this Agreement shall not terminate.
The Executive represents to the Company that he is aware of no facts or
circumstances applicable to him that would prevent the issuance of the visas
described in this Section.

         9.       MISCELLANEOUS.

accordance with the laws of the State of Florida, without regard to the conflict
of law principles thereof.

                  (i) This Agreement is personal to the Executive and without
         the prior written consent of the Company shall not be assignable by the
         Executive otherwise than by will or the laws of descent and
         distribution.

                  (ii) This Agreement shall inure to the benefit of and be
         enforceable by the Executive's legal representatives.

                  (iii) This Agreement shall inure to the benefit of and be
         binding upon the Company and its successors and assigns. The Company
         will require any successor (whether direct or indirect, by purchase,
         merger, consolidation or otherwise) to all or substantially all of the
         business and/or assets of the Company or, if the last sentence of
         Section 5 is applicable, Zenith Goldline, to expressly assume and agree
         to perform this Agreement in the same manner and to the same extent
         that the Company would be required to perform it if no such succession
         had taken place. As used in this Agreement, "Company" shall mean the
         Company as hereinbefore defined and any successor to its business
         and/or assets which assumes and agrees to perform this Agreement by
         operation of law or otherwise.

phrases, sentences, clauses or sections contained in this Agreement shall not
affect the enforceability of the remaining portions of this Agreement or any
part thereof, all of which are inserted conditionally on their being valid in
law, and, in the event that any one or more of the words, phrases, sentences,
clauses or sections contained in this Agreement shall be declared invalid, this
Agreement shall be construed as if such invalid word or words, phrase or
phrases, sentence or sentences, clause or clauses, or section or sections had
not been inserted. If such invalidity is caused by length of time or size of
area, or both, the otherwise invalid provision will be considered to be reduced
to a period or area which would cure such invalidity.

         (E) WAIVERS. The waiver by either party hereto of a breach or violation
of any term or provision of this Agreement shall not operate nor be construed as
a waiver of any subsequent breach or violation.

         (F) DAMAGES. Nothing contained herein shall be construed to prevent the
Company or the Executive from seeking and recovering from the other damages
sustained by either or both of them as a result of its or his breach of any term
or provision of this Agreement, except that the payment required to be made by
the Company to the Executive pursuant to Sections 4 and 8 shall be the
Executive's exclusive remedy for any termination of this Agreement pursuant to
such sections.

         (G) NO THIRD PARTY BENEFICIARY. Nothing expressed or implied in this
Agreement is intended, or shall be construed, to confer upon or give any person
(other than the parties hereto and, in the case of Executive, his heirs,
personal representative(s) and/or legal representative) any rights or remedies
under or by reason of this Agreement.

         (H) MISCELLANEOUS. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement. To the extent
that the Executive is successful in any legal proceeding against the Company
involving this Agreement, the Company agrees to pay, to the full extent
permitted by law, all legal fees and expenses which the Executive may reasonably
incur in connection with such proceeding.

         (I) MEDIATION. The Company and the Executive agree so submit any
controversy or claim arising out of or relating to this Agreement to mediation
with a mutually agreeable mediator in Dade County, Florida, prior to instituting
any legal proceeding.

         10.      CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY.

<PAGE>

         (a) Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any payment or distribution by the Company to
or for the benefit of the Executive, whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise (a
"PAYMENT"), would be nondeductible by the Company for Federal income tax
purposes because of Section 280G of the Code, then the aggregate present value
of amounts payable or distributable to or for the benefit of the Executive
pursuant to this Agreement (such payments or distributions pursuant to this
Agreement are hereinafter referred to as "AGREEMENT PAYMENTS") shall be reduced
to the Reduced Amount. The "REDUCED AMOUNT" shall be an amount expressed in
present value which maximizes the aggregate present value of Agreement Payments
without causing any Payment to be nondeductible by the Company because of
Section 280G of the Code. Anything to the contrary notwithstanding, if the
Reduced Amount is zero and it is determined further that any Payment which is
not an Agreement Payment would nevertheless be nondeductible by the Company for
Federal income tax purposes because of Section 280G of the Code, then the
aggregate present value of Payments which are not Agreement Payments shall also
be reduced (but not below zero) to an amount expressed in present value which
maximizes the aggregate present value of Payments without causing any Payment to
be nondeductible by the Company because of Section 280G of the Code. For
purposes of this Section, present value shall be determined in accordance with
Section 280G(d)(4) of the Code. Any amount which is not paid in the taxable year
in which it was originally scheduled to be paid as a result of the postponement
thereof pursuant hereto shall be payable in the next succeeding taxable year in
which such payment will not result in the disallowance of a deduction pursuant
to either Section 162(m) or 280G of the Code; provided, however, that all
postponed payments shall be placed in a Rabbi trust or similar vehicle for the
benefit of the Executive in such a way that the amounts so transferred are not
taxable to such person or deductible by the Company until payment from such
vehicle to the Executive is made. In the event a payment has been made to the
Executive, but then disallowed as a deduction by the Internal Revenue Service
and return of the payment is required into the trust, said payment to the
Executive shall be treated as a loan and said payment to the trust shall be
treated as repayment of said loan. The Company shall not pledge, hypothecate or
otherwise encumber any amounts held in the trust or other similar vehicle for
the benefit of the Executive hereunder.

         (b) All determinations required to be made under this Section shall be
made by the Company's independent public accountants (the "ACCOUNTING FIRM"),
which shall provide (i) detailed supporting calculations both to the Company and
the Executive within 20 business days of the termination of Executive's
employment or such earlier time as is requested by the Company, and (ii) an
opinion to the Executive that he has substantial authority not to report any
excise tax on his Federal income tax return with respect to any Payments. Any
such determination by the Accounting Firm shall be binding upon the Company and
the Executive. The Executive shall determine which and how much of the Payments
shall be eliminated or reduced consistent with the requirements of this Section,
provided that, if the Executive does not make such determination within ten
business days of the receipt of the calculations made by the Accounting Firm,
the Company shall elect which and how much of the Payments shall be eliminated
or reduced consistent with the requirements of this Section and shall notify the
Executive promptly of such election. Within five business days thereafter, the
Company shall pay to or distribute to or for the benefit of the Executive such
amounts as are then due to the Executive under this Agreement. All fees and
expenses of the Accounting Firm incurred in connection with the determinations
contemplated by this Section shall be borne by the Company.

         (c) As a result of the uncertainty in the application of Section 280G
of the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Payments will have been made by the Company which
should not have been made ("OVERPAYMENT") or that additional Payments which will
not have been made by the Company could have been made ("UNDERPAYMENT"), in each
case, consistent with the calculations required to be made hereunder. In the
event that the Accounting Firm, based upon the assertion of a deficiency by the
Internal Revenue Service against the Executive which the Accounting Firm
believes has a high probability of success, determines that an Overpayment has
been made, any such Overpayment paid or distributed by the Company to or for the
benefit of the Executive shall be treated for all purposes as a loan AB INITIO
to the Executive which the Executive shall repay to the Company together with
interest at the applicable federal rate provided for in Section 7872(f)(2) of
the Code; provided, however, that no such loan shall be deemed to have been made
and no amount shall be payable by the Employee to the Company if and to the
extent such deemed loan and payment would not either reduce the amount on which
the Executive is subject to tax under Section 1 and Section 4999 of the Code or
generate a refund of such taxes. In the event that the Accounting Firm, based
upon controlling precedent or other substantial authority, determines that an
Underpayment has occurred, any such Underpayment shall be promptly paid by the
Company to or for the benefit of the Executive together with interest at the
applicable federal rate provided for in Section 7872(f)(2) of the Code.

         IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
the date first above written.
