each outstanding stock option (the "Stock Options") held by Mr. Bruggeman as
listed on Exhibit A attached hereto, shall be accelerated such that, as of the
Effective Date of this Agreement, the number of shares vested under the Stock
Options shall equal the number of shares that would have vested through June 10,
1999 had he remained an employee of the Company continuously through that date.
Should Mr. Bruggeman choose to exercise any such Stock Options, he must do so
within 90 days of the Separation Date.  The Stock Options will terminate 90 days

agreement, or restricted stock bonus agreement) from the Company shall cease
upon the Separation Date.

     10.  Health Insurance.  To the extent provided by the federal COBRA law or,
if applicable, state insurance laws, and by the Company's current group health
insurance policies, Mr. Bruggeman will be eligible to continue his health,
prescription drug, vision and dental insurance benefits.  Mr. Bruggeman will be
provided with a separate notice of his COBRA rights.  In the event that Mr.
Bruggeman elects continued coverage under COBRA, the Company will pay his COBRA
insurance premiums up until the earlier of (i) eighteen (18) months from the
Separation Date, or (ii) the date in which Mr. Bruggeman begins employment with
another company or business entity (the "Premium Period").  Thereafter, Mr.
Bruggeman shall be solely responsible for the payment of his COBRA premiums, if
any.  The Company further agrees that, in the event Mr. Bruggeman dies during
the Premium Period, it will continue to pay Mr. Bruggeman's dependents' COBRA
insurance premiums for the duration of the Premium Period.

     11.  Key Man Life Insurance.  The Company agrees that it will cancel the
key man life insurance policy on Mr. Bruggeman's life within a reasonable period
of time following the execution of this Agreement.

     12.  Condition Precedent.  This Agreement is expressly conditioned on the
closing of the purchase of 793,455 shares of Mr. Bruggeman's Series B
Convertible Preferred Stock (the "Shares") by certain current shareholders of
such stock at a price of $1.09 per share (the "Transaction").  This Transaction
is to be completed within a reasonable period of time after the execution of the
Agreement, but no later than April 12, 1999.  The Company has prepared the
necessary documentation for the Transaction which is submitted to Mr. Bruggeman
concurrent with this Agreement and which Mr. Bruggeman agrees he will execute.

<PAGE>

purchase price for the Shares is not tendered by the purchasing shareholders,
for whatever reason (other than Mr. Bruggeman's refusal to accept the purchase
price), this Agreement shall be rescinded and Mr. Bruggeman will return to
Diversa any sums or amounts paid to him hereunder; provided, however, in such
event, Mr. Bruggeman may retain the benefits provided for in paragraphs 2, 3, 4,
5 and 10 pursuant to the terms and conditions of each respective paragraph.

     13.  Other Compensation and Benefits.  Except as expressly provided herein,

Separation Date, he will not, either directly or through others, solicit or
attempt to solicit any person (including any entity) who is then an employee,
consultant or independent contractor of the Company to terminate his, her or its
relationship with the Company in order to become an employee, consultant or
independent contractor to or for any other person or entity.

     15.  Proprietary Information Obligations.  Mr. Bruggeman hereby
acknowledges his continuing obligations under the Employee Invention and Non-
Disclosure Agreement not to use or disclose any confidential or proprietary
information of the Company without prior written authorization from a duly
authorized representative of the Company.  A copy of Mr. Bruggeman's Employee
Invention and Non-Disclosure Agreement is attached hereto as Exhibit B.  Mr.
Bruggeman acknowledges that irreparable damage would result to the Company if he
breached the provisions of this paragraph 12, and the Company would not have an
adequate remedy at law for such a breach or threatened breach.  In the event of
such a breach or threatened breach, Mr. Bruggeman agrees that the Company, may,
notwithstanding anything to the contrary herein contained, and in addition to
the other remedies which may be available to it, seek to enjoin him, together
with all those persons associated with him, from the breach or threatened breach
of such covenants.

     16.  Company Property.  Mr. Bruggeman agrees to return to the Company,
within ten (10) days of the execution of the Agreement, all Company documents
(and all copies thereof) and other Company property in his possession, or his
control, including, but not limited to, Company files, notes, drawings, records,
business plans and forecasts, financial information, specifications, computer-
recorded information, tangible property, credit cards, entry cards,
identification badges and keys; and, any materials of any kind which contain or
embody any proprietary or confidential material of the Company (and all
reproductions thereof); provided, however, that if Mr. Bruggeman discovers any
such documents or property in his possession after the expiration of such ten
(10) day period, Mr. Bruggeman agrees to return such property to the Company as
soon as practicable following discovery.

     17.  Nondisparagement.  Mr. Bruggeman agrees that he will not at any time
intentionally disparage the Company in any manner likely to be harmful to the
Company, its business reputation, or the personal or business reputation of its
directors, stockholders or employees, and the Company agrees that neither it nor
its officers and directors will at any time intentionally disparage Mr.
Bruggeman or his personal or business reputation, provided that each

                                      3.
<PAGE>

party shall respond accurately and fully to any question, inquiry or request for
information when required by legal process.

corporate reporting or disclosure requirements; and (c) the parties may disclose

seven (7) days following the execution of this Agreement to revoke the
Agreement; (e) this Agreement shall not be effective until the date upon which
the revocation period has expired, which shall be the eighth day after this
Agreement is executed by Mr. Bruggeman, provided that the Company has also
signed the Agreement by that date (the "Effective Date").

     21.  Section 1542 Waiver.  Mr. Bruggeman acknowledges that he has read and
understands Section 1542 of the Civil Code of the State of California which
reads as follows:

          A general release does not extend to claims which the creditor does
          not know or suspect to exist in his favor at the time of executing the
          release, which if known by him must have materially affected his
          settlement with the debtor.

Mr. Bruggeman hereby expressly waives and relinquishes all rights and benefits
under that section and any law or legal principle of similar effect in any
jurisdiction with respect to the release granted in this Agreement.

     22.  Release of Claims by the Company. The Company hereby releases, acquits
and forever discharges Mr. Bruggeman and his agents, successors, assigns and
affiliates from any and all claims, liabilities, demands, causes of action,
costs, expenses, attorneys' fees, damages, indemnities and obligations of every
kind in nature, in law, equity or otherwise arising out of or in any way related
to agreements, events, acts or conduct at any time prior to and including the
date the Company executes this Agreement, relating to any act or omission by Mr.
Bruggeman within the authorized course and scope of his employment with the
Company, with the exception of any claim arising out of his obligations under
this Agreement, including the Employee Invention and Non-Disclosure Agreement or
any other obligations relating to the proprietary information of the Company.
The Company, its officers, directors and managerial employees acknowledge that
as of the Effective Date they have no knowledge, information or belief that Mr.
Bruggeman has performed any act or omission outside the authorized course and
scope of his employment.

     23.  No Admissions.  It is understood and agreed by Mr. Bruggeman and the
Company that this Agreement represents a compromise settlement of various
matters, and that the promises and payments in consideration of this Agreement
shall not be construed to be an admission of any liability or obligation by
either party to the other party or to any other person.

     24.  Notices.  All notices, instructions and other communications given
hereunder or in connection herewith shall be in writing.  Any such notice,
instruction or communication shall be sent either (a) by registered or certified

American Arbitration Association ("AAA") in San Diego under the then existing

or parts of this provision had never been contained herein, consistent with the
general intent of the parties insofar as possible.

                       Recombinant BioCatalysis(TM) Inc.
                EMPLOYEE INVENTION AND NON-DISCLOSURE AGREEMENT

This Employee Invention and Non-Disclosure Agreement is made this 15th day of
September, 1996 ("Effective Date") by and between RECOMBINANT BIOCATALYSIS(TM)
INC., a Delaware corporation with a principal place of business at Elmwood Court
Two, 512 Elmwood Avenue, Sharon Hill, PA 19079-1003, and a further place of
business at 505 coast Boulevard South, La Jolla, California 92037 ("RBI"), and
T. J. Bruggeman, an individual having an address at 6 ________________________
("Employee").

     In consideration of the mutual promises and other good and valuable
consideration, and as part of the terms of employment of Employee by RBI, the
parties agree as follows:

INVENTIONS

     1.   Employee agrees to disclose to RBI promptly in writing any and all
inventions, developments, discoveries, improvements and ideas, whether
patentable or not; (a) which are made, discovered, and/or conceived by Employee
alone or with others in the course of his or her employment or provision of
services to RBI; (b) which are based on or utilize RBI Proprietary Information
(as defined in Paragraph 6); or (c) which result or arise from or relate to the
use of RBI's facilities, equipment, materials, funds, or actual or demonstrably
anticipated research or development.  All such improvements, inventions,
developments, discoveries, ideas, and intellectual property rights, shall be
referred to individually and collectively as "Developed Technology."  RBI shall
receive such disclosures in confidence.  To the extent required by contracts
between RBI and the United States or any of its agencies, full title to certain
patents and inventions shall be in the United States.

     2.   Employee agrees that all Developed Technology made, discovered or
conceived by Employee, either solely or in collaboration with any other person,
during the term of Employee's employment with RBI, whether or not patented or
copyrighted, is and shall remain the sole and exclusive property of RBI, its
successors and assigns.  Employee irrevocably agrees to assign and does assign
to RBI or its nominees, successors or assigns, all right, title and interest in
and to Developed Technology.  Employee agrees to execute any and all papers and
perform any and all acts as may be necessary to perfect such assignment.

     3.   With regard to the copyright laws of the United States, RBI notes that
U.S. Copyright Act (S) 101 defines the term "work made for hire," in pertinent
part, as a "work prepared by an employee within the scope of his or her
employment."  U.S. Copyright Act (S) 201(b) provides that "[i]n the case of a
work made for hire, the employer or other person for whom the work was prepared
is considered the author for purposes of this title and, unless the parties have
expressly agreed otherwise in a written instrument signed by them, owns all of
the rights comprised in the copyright."  RBI further notes that the judicial
decisions under the U.S. Copyright Act broadly interpret the phrase "within the
scope of his or her employment."  This phrase has been applied to cover, among
other things, some works created by an employee at
<PAGE>

home on his own time and for no additional pay, without any request by the
employer. RBI intends to assert its ownership and other rights in the "work made
for hire" are to the fullest legally permissible extent.

     4.  In the event that RBI makes or proposes to make any United States or
foreign patent application relating to Developed Technology owned by RBI
pursuant to this Agreement, Employee shall cooperate fully with RBI and its
patent counsel in preparing and prosecuting any such application.  Employee
agrees to execute, acknowledge and deliver all such papers, including, but not
limited to, applications for patents, applications for copyright registration
and applications for trademark registration as may be necessary or appropriate
to enable RBI to publish or protect Developed Technology owned by RBI by
patents, copyrights or otherwise in the name of RBI or its nominees, successors
or assigns.  Employee further agrees to render all such assistance as RBI may
require in any patent office, proceeding, litigation or other administrative,
judicial or related proceeding in the United States or foreign country,
involving Developed Technology owned by RBI.

     5.   In the event RBI is unable, after reasonable effort to secure
Employee's signature on any of the documents referenced in Paragraphs 2 and 4
whether because of Employee's physical or mental incapacity or for any other
reason whatsoever, Employee irrevocably designates and appoints RBI and its duly
authorized officers and agents as Employee's agent and attorney-in-fact, for
purposes of effecting any or all prosecutions and/or issuances of any such
copyright, patent or trademark protection or other analogous protection.

CONFIDENTIAL INFORMATION

     6.   For purposes of this Agreement, the phrase "RBI Proprietary
Information" includes without limitation the following:

          (a) technical information, including patent strategy, information
encompassed by Developed Technology or trade secrets, locations and sources of
bio-material, methods of harvesting bio-material, experiment and research
design, results, techniques and processes; biological materials, including but
not limited to enzymes and clones; work in progress; manufacturing and process
know-how; laboratory notebooks, research journals, idea notebooks, notes and
letters; concepts; ideas; apparatus and equipment design; and computer software;

          (b) technical management information, including technical manuals,
product proposals, status reports, performance objectives and criteria and
analyses of areas for business development; and

          (c) business information, including cost, pricing, project, financial,
accounting and personnel information, notes, letters, business strategies,
plans, proposals, projections and forecasts, customer lists, customer
information and sales and marketing plans, proposals, projections, efforts,
information and data.

     "RBI Proprietary Information" shall also include any and all information
and materials received by RBI or Employee from a third party subject to an
obligation of confidentiality and/or non-disclosure.
<PAGE>

     7.   Developed Technology owned by RBI and RBI Proprietary Information
shall be considered confidential and trade secret and shall not be disclosed to
any person or entity or used by Employee for any purpose at any time during or
following the termination or cessation of Employee's employment with RBI, except
as required in Employee's performance of job duties for RBI.  Nothing in this
Agreement shall restrict Employee's ability to make such disclosures during the
course of his or her employment as may be necessary or appropriate to the
effective and efficient discharge of the duties and responsibilities of Employee
or as such disclosures may be required by law.  Failure by  RBI to mark any of
RBI Proprietary Information as "confidential" or "proprietary" shall not affect
its status as RBI Proprietary Information under the terms of this Agreement.

COMPETITIVE ACTIVITIES

     8.   During the term of Employee's employment with RBI, and for a period of
two (2) years after the termination or cessation of Employee's employment with
RBI, Employee shall not, without the prior written approval of RBI, alone or as
a partner, officer, director, consultant, employee, stockholder, agent,
contractor or otherwise, engage in any employment, consulting, business or other
