                                                                  EXECUTION COPY

shall commence on the Effective Date, and unless terminated at an earlier date
in accordance with Section 9 hereof, and shall extend through the third
anniversary of the Effective Date, subject to automatic renewal for an
additional twenty-four (24) months, unless either party hereto receives written
notice from the other party no later than ninety (90) days prior to the third
anniversary of the Effective Date (a "first term notice of non-renewal") that
such other party does not wish for the term hereof to continue beyond the third
anniversary of the Effective Date, in which event the term hereof and the
Executive's employment shall end at 5:00 PM on the third anniversary of the

that such other party does not wish for the term hereof to continue beyond such
twelve (12) month notice period. For the purposes of this Agreement, a "first
term notice of non-renewal" and an "extension term notice of non-renewal" shall
be referred to collectively as a "notice of non-renewal."

         (b) Performance of Duties.

                  (i) The Executive agrees to serve the Company faithfully and
         to the best of his ability and to devote his full time, attention and
         efforts to the business and affairs of the Company during his
         employment by the Company.

                  (ii) The Executive has provided the Company with a draft of a
         Consulting Agreement between the Executive and Genzyme Oncology
         ("Genzyme") (such draft substantially in the form as previously sent to
         the Company being the "Consulting Agreement"), which, to the best of
         the Executive's knowledge, is the only agreement that could arguably
         restrict or interfere with his employment activities subsequent to the
         termination of his employment with his former employer. Company agrees
         that the execution by the Executive of and the performance by the
         Executive of his obligations under the Consulting Agreement shall not
         constitute a breach of this Agreement, and Company specifically
         authorizes the Executive to fulfill the terms of the Consulting
         Agreement.

                  (iii) The Executive agrees that he will not use on behalf, or
         for the benefit, of the Company, or disclose to the Company, any
         confidential information of or concerning his former employer or
         Genzyme. It is the Company's intention that the Executive not breach
         any confidentiality agreement to which he is party, including, without
         limitation, any such agreement he may have with his former employer or
         Genzyme. The Executive will not render or perform services for any
         other corporation, firm, entity or person which are inconsistent with
         the provisions of this Agreement other than pursuant to the terms of
         the Consulting Agreement.

                  (iv) While he remains employed by the Company, the Executive
         may participate in reasonable charitable activities and personal
         investment activities so long as such activities do not conflict or
         interfere with the performance of his obligations under this Agreement.

         (c) The Executive's Representations and Warranties. The Executive
represents and warrants to the Company that his entering into and performing
this Agreement will not constitute a breach of any employment, consulting,
non-competition or other agreement to which he is a party or any other
obligation of the Executive (including, without limitation, the Consulting
Agreement). The Executive represents and warrants to the Company that he has not
been debarred under the Generic Drug Enforcement Act of 1992 (Sections 306-308
of the Federal Food, Drug and Cosmetic Act) nor has the Executive received
notice of action or threat of action of debarment. The Executive shall comply
with the Company's material policies governing the conduct of senior executives,
including, without limitation, its Substance Abuse Policy, during the Term.

         (a) Base Salary. The Company shall pay to the Executive, less

annual rate of Three Hundred Fifteen Thousand Dollars ($315,000) per year, which
Base Salary shall be paid in accordance with the Company's normal payroll
procedures and policies for its senior management. The compensation payable to
the Executive during each fiscal year of the Company beginning after the
Effective Date shall be established by the Board or the Compensation Committee
thereof following an annual performance review, but in no event shall the annual
rate of Base Salary for any successive year of the Term be less than the highest
annual rate of Base Salary in effect during the previous year of the Term.

         (b) Annual Bonus. The Executive shall be entitled to participate in the
Company's bonus plan for management and any successor bonus plan covering
management with respect to each fiscal year of the Company ending during the
Term (the "Bonus Plan"). Under the Bonus Plan, the Executive shall be eligible
to receive a performance-based cash bonus for each fiscal year ending during the
Term in an amount, and based on objective individual and/or corporate
objectives, targets and factors (and evaluation as to the extent of achievement
thereof), to be established and determined by the Board in its discretion
following consultation between the Chief Executive Officer and the Executive
prior to, or within sixty (60) days after the commencement of, each fiscal year.
Under the Bonus Plan for the Executive, (i) the minimum cash bonus shall be zero
(0), (ii) the target cash bonus shall equal 50% of the Base Salary (the "Target
Bonus"), and (iii) the maximum cash bonus shall equal 82.5% of Base Salary. In
addition to the foregoing amounts, within five (5) days after Executive's first
day of employment, the Company shall pay to Executive a bonus in cash in the
amount of $125,000.

         (c) Participation in Benefit Plans; Indemnification. While he is
employed by the Company, the Executive shall also be eligible to participate in
any incentive and employee benefit plans or programs which may be offered by the
Company to the extent that the Executive meets the requirements for each
individual plan and in all other plans in which Company executives participate.
The Company provides no assurance as to the adoption or continuance of any
particular employee benefit plan or program, and, except as provided at Section
10 hereof, the Executive's participation in any such plan or program shall be
subject to the provisions, rules and regulations applicable thereto. During the
Executive's employment with the Company, and thereafter, the Company shall
indemnify the Executive and hold him harmless from and against any claim,
liability and expense (including, without limitation, reasonable attorney fees)
made against or incurred by him in connection with his employment by the
Company, and cover him under a policy of directors and officers liability
insurance, in a manner and to an extent that is not less favorable to the
Executive as the indemnification protection, and liability insurance coverage,
that is afforded by the Company to any other senior officer or director.

         (d) Expenses. The Company will pay or reimburse the Executive for all
reasonable and necessary out-of-pocket expenses incurred by him in the
performance of his duties under this Agreement, subject to the Company's normal
policies for expense verification.

                  (i) The Company shall also reimburse Executive for the

         necessary moving and interim housing expenses incurred in connection
         with the move of Executive and his family from San Antonio, Texas to
         the New Jersey area. Such reasonable and necessary moving and interim

         closing costs relating to the acquisition of his home in the New Jersey
         area, (2) interest payments on the mortgage loan relating to his home
         in Texas until his home in Texas shall have been sold and (3) extra or
         redundant costs (other than the principal payments on his mortgage loan
         relating to his home in Texas) associated with, or incurred in
         connection with, the continued ownership of his home in Texas pending
         its sale. In addition, the Company shall provide an additional payment
         to Executive such that after taking into account any taxes on such
         payment, Executive shall retain a sufficient amount equal to any income
         tax liability incurred by Executive in connection with the foregoing
         payments and reimbursements under this subparagraph (d)(i). If the
         Executive voluntarily terminates his employment for Good Reason
         (defined below), he shall not be obligated to repay any amount provided
         to the Executive under this Section 4(d)(i). In the event of any
         inconsistency between this Agreement and the Company's relocation
         policy, this Agreement shall control.

options to purchase shares of common stock of the Company ("Common Stock")
pursuant to the Company's 2001 Incentive Stock Plan, as amended (the "Stock

fiscal year, for the costs of all tax return preparation, including any United

professionals who will provide such services. The Company will pay Executive's
professional fees incurred to negotiate and prepare this Agreement and related
agreements, in an amount not to exceed $7,500.

         (i) Certain Legal Expenses. In the event of any legal proceedings,

connection with such proceedings.

         5. Noncompetition and Confidentiality Covenant.

         (a) Noncompetition. The "Noncompete Period" shall be the Term plus the
one (1) year period immediately following termination of the Executive's
employment with the Company irrespective of the reason for, or circumstances
surrounding, such termination. In consideration for the compensation payable to
the Executive pursuant to this Agreement, including without limitation the stock
options and Restricted Stock granted to the Executive hereunder, during the
Noncompete Period, the Executive will not directly, or indirectly, whether as an
officer, director, stockholder, partner, proprietor, associate, employee,
consultant, representative or otherwise, become, or be interested in or
associated with any other person, corporation, firm, partnership or entity,
engaged to a significant degree in (x) developing, manufacturing, marketing or
selling enzymes, protein-based biopharmaceuticals or other pharmaceuticals that
are modified using polyethylene glycol ("PEG"), (y) developing, marketing or
selling single-chain antigen-binding proteins or (z) any specific technology or
specific area of business in which the Company becomes involved to a significant
degree during the Term. For purposes of the preceding sentence, to determine
whether any entity is engaged in such activities to a "significant degree",
comparison will be made to the Company's operations at that time. In other
words, an entity will be deemed to be engaged in an activity to a significant
degree if the number of employees and/or amount of funds devoted by such entity
to such activity would be material to the Company's operations at that time. The
Executive is hereby prohibited from ever using any of the Company's proprietary
information or trade secrets to conduct any business, except for the Company's
business while the Executive is employed by the Company as provided in Section
5(b) hereof. The provisions contained in this Section 5(a) shall survive the
termination of the Executive's employment pursuant to Section 9 hereof or
otherwise. In the event the Executive breaches any of the covenants set forth in
this Section 5(a), the running of the period of restriction set forth herein
shall be tolled for the period during which the breach exists and recommence
upon the Executive's compliance with the terms of this Section 5(a).

                                       5
<PAGE>

         (b) Confidentiality.

                  (i) The Executive acknowledges that, by reason of his
         employment by the Company, he will have access to confidential
         information of the Company, including, but not limited to, information
         and knowledge pertaining to products, inventions, discoveries,
         improvements, innovations, designs, ideas, trade secrets, proprietary
         information, manufacturing, packaging, advertising, marketing,
         distribution and sales methods, sales and profit figures, customer and
         vendor lists and relationships between the Company and dealers,
         distributors, sales representatives, wholesalers, customers, suppliers
         and others who have business dealings with them (collectively,
         "Confidential Information"). The Executive acknowledges that such
         Confidential Information is a valuable and unique asset of the Company
         and covenants that, both during and after the Term, he will not
         disclose any Confidential Information to any person or entity, nor use
         the Confidential Information for any purpose, except as his duties as
         an employee of the Company may require, without the prior written
         authorization of the Board. The obligation of confidentiality imposed
         by this Section 5(b) shall not apply to Confidential Information that
         otherwise becomes generally known to the public through no act of the
         Employee in breach of this Agreement or any other party in violation of
         an existing confidentiality agreement with the Company or which is
         required to be disclosed by a specific order of a court or governmental
         agency.

                  (ii) All Confidential Information, as well as any other
         records, designs, patents, business plans, financial statements,
         manuals, memoranda, lists, research and development plans and products,
         and other property delivered to or compiled by the Executive for or on
         behalf of the Company or its vendors or customers that pertain to the
         business of the Company shall be and remain the property of the
         Company, and be subject at all times to its discretion and control.
         Likewise, all Confidential Information, as well as any other formulae,
         correspondence, reports, records, charts, advertising materials and
         other similar data pertaining to the business, activities or future
         plans of the Company (and all copies thereof) that are collected by the
         Executive shall be delivered promptly to the Company without request by
         it upon termination of the Executive's employment.

         (c) Nonsolicitation of Employees. During the Noncompete Period, the
Executive shall not, directly or indirectly, personally or through others,
encourage to leave employment with the Company, solicit for employment, or
advise or recommend to any other person, firm, business, or entity that they
employ or solicit for employment, any employee of the Company or of any parent,
subsidiary, or affiliate of the Company.

         6. Ventures. If, during the term of his employment, the Executive is
engaged in or associated with the planning or implementing of any project,
program, venture or relationship involving the Company and a third party or
parties, all rights in such project, program, venture or relationship shall
belong to the Company. Except as approved by the Board, the Executive shall not
be entitled to any interest in such project, program, venture or relationship or
to any commission, finder's fee or other compensation in connection therewith
other than the compensation to be paid to the Executive as provided in this
Agreement.

                                       6

         7. Acknowledgment. The Executive agrees that the covenants and
agreements contained in Section 5 hereof are material to this Agreement; that
each of such covenants is reasonable and necessary to protect and preserve the
Company's interests, properties and business; that irreparable loss and damage
will be suffered by the Company should the Executive breach any of such
covenants and agreements; that each of such covenants and agreements is
separate, distinct and severable not only from the other of such covenants and
agreements but also from the other and remaining provisions of this Agreement;
that the unenforceability or breach of any such covenants or agreement shall not
affect the validity or enforceability of any other such covenant or agreement or
any other provision of this Agreement; and that, in addition to other remedies
available to it, the Company shall be entitled to both temporary and permanent
injunctions and any other rights or remedies it may have, at law or in equity,
to end or prevent a breach or contemplated breach by the Executive of any such
covenants or agreements.

         (a) Geographic Extent of the Executive's Obligations Concerning Section
5. The restrictions contained in Section 5 are limited to the United States.
Given the nature of the Company's business, the restrictions contained in
Section 5 cannot be limited to any particular geographic region within the
United States. Therefore, the obligations of the Executive under Section 5 shall
apply to any geographic area in which the Company (i) has engaged in business
during the period of the Executive's employment with the Company or (ii) has
otherwise established during the period of the Executive's employment with the
Company its goodwill, business reputation or any customer or vendor relations.

         (b) Limitation of Covenant. Ownership by the Executive, as a passive
investment, of less than five percent (5%) of the outstanding shares of capital
stock or equity of any corporation or other entity that is publicly traded shall
not constitute a breach of Section 5.

         (c) Blue Pencil Doctrine. The restrictions contained in Section 5 are
limited to the United States. If the duration or geographical extent of, or
business activities covered by, Section 5 are in excess of what is valid and
enforceable under applicable law, then such provision shall be construed to
cover only that duration, geographical extent or activities that are valid and
enforceable. The Executive acknowledges the uncertainty of the law in this
respect and expressly stipulates that this Agreement be given the construction
which renders its provisions valid and enforceable to the maximum extent (not
exceeding its express terms) possible under applicable law.

         (d) Disclosure. The Executive shall disclose to any prospective
employer, prior to accepting or continuing employment, the existence of Section
5 of this Agreement and shall provide such prospective employer with a copy of
Section 5 of this Agreement. The obligation imposed by this subsection 7(d)
shall terminate one year after the termination of the Executive's employment
with the Company.

         8. Intellectual Property and Related Matters.

         (a) Disclosure and Assignment. The Executive will promptly disclose in
writing to the Company complete information concerning each and every product,
invention, discovery, practice, process or method, whether patentable or not,
made, developed, perfected, devised, conceived or first reduced to practice by
the Executive, either solely or in collaboration with others, during the Term,
or within six months thereafter, whether or not during regular working hours,
relating either directly or indirectly to the business, products, practices or
techniques of the Company ("Developments"). The Executive hereby acknowledges
that any and all of the Developments are the property of the Company and hereby
assigns and agrees to assign to the Company any and all of the Executive's
right, title and interest in and to any and all of the Developments. At the
request of the Company, the Executive will confer with the Company and its
representatives for the purpose of disclosing all Developments to the Company,
as the Company shall reasonably request during the period ending three (3) years
after the end of the Term.

not apply to any Development meeting the following conditions:

                  (i) such Development was developed entirely on the Executive's
         own time;

                  (ii) such Development was made without the use of any Company
         equipment, supplies, facility or trade secret or customer information;

                  (iii) such Development does not relate (A) directly to the
         business of the Company or (B) to the Company's actual or demonstrably
         anticipated research or product or customer development; and

                  (iv) such Development does not result from any work performed
         by the Executive for the Company.

         (c) Assistance of the Executive. Upon request and without further
compensation therefor, but at no expense to the Executive, the Executive will do
all lawful acts, including but not limited to, the execution of papers and
lawful oaths and the giving of testimony, that in the opinion of the Company,
may be necessary or desirable in enforcing the Company's intellectual property
and trade secret rights, and for perfecting, affirming and recording the
Company's complete ownership and title thereto.

         (d) Records. The Executive will keep complete, accurate and authentic
accounts, notes, data and records of the Developments in the manner and form
requested by the Company. Such accounts, notes, data and records shall be the
property of the Company, and, upon the earlier of the Company's request or the
conclusion of his employment, the Executive will promptly surrender same to the
Company.

         (e) Copyrightable Material. All right, title and interest in all
copyrightable material that the Executive shall conceive or originate, either
individually or jointly with others, and which arise out of the performance of
his duties under this Agreement or otherwise as an employee of the Company, will
be the property of the Company and are by this Agreement assigned to the Company
along with ownership of any and all copyrights in the copyrightable material.
Upon request and without further compensation therefor, but at no expense to the
Executive, the Executive shall execute all papers and perform all other acts
necessary to assist the Company to obtain and register copyrights on such
materials in any and all countries. Where applicable, works of authorship
created by the Executive for the Company in performing his responsibilities
under this Agreement shall be considered "works made for hire," as defined in
the U.S. Copyright Act.

         (f) Know-How and Trade Secrets. All know-how and trade secret
information conceived or originated by the Executive that arises out of the
performance of his obligations or responsibilities under this Agreement or any
related material or information shall be the property of the Company, and all
rights therein are by this Agreement assigned to the Company.

         9. Termination of Employment.

         (a) Grounds for Termination. The Executive's employment pursuant to
this Agreement shall terminate prior to the expiration of the Term in the event

                  (iii) The Board elects to terminate the Executive's employment
         for "Cause" and notifies the Executive in writing of such election,

                  (iv) The Board elects to terminate the Executive's employment
         without "Cause" and notifies the Executive in writing of such election,
         or

                  (v) The Executive elects to terminate his employment, without
         Good Reason and without liability, and notifies the Board in writing of
         such election.

         If the Executive's employment is terminated pursuant to clause (i),
(ii) or (iii) of this Section 9(a), such termination shall be effective
immediately. If the Executive's employment is terminated pursuant to subsection
(iv) of this Section 9(a), such termination shall be effective 30 days after
receipt of the notice of termination, and if pursuant to subsection (v) of this
Section 9(a), such termination shall be effective 15 days after receipt of such
notice.

         (b) "Cause" Defined. "Cause" shall mean (i) the willful engaging by the
Executive in illegal conduct or gross misconduct that is demonstrably and
materially injurious to the Company, (ii) the Executive's willful refusal to
perform his duties hereunder (other than any such failure resulting from illness
or incapacity) which refusal is demonstrably and materially injurious to the
Company, but only after the Executive has first received written notice of such
alleged refusal, and such refusal shall have continued for fifteen (15) days
after such notice without cure by the Executive, or (iii) the Executive's
material breach of his obligations under this Agreement which breach is
demonstrably and materially injurious to the Company, but only after the
Executive has first received written notice of such alleged breach and has
failed to cure such breach within fifteen (15) days after such notice; provided,
however, that if the breach is not one that can be reasonably cured, then the
foregoing requirement in this Clause (iii) for notice and opportunity to cure
shall not apply. For purposes of this Section 9(b), no act or failure to act on
the Executive's part shall be deemed "willful" unless done, or omitted to be
done, by the Executive not in good faith and without reasonable belief that the
Executive's action or omission was in the best interests of the Company.
Notwithstanding the foregoing, the Executive shall not be deemed to have been
terminated for Cause unless and until the Company delivers to the Executive a
copy of a resolution duly adopted by the affirmative vote of not less than a
majority of the Board (not including the Executive, if he is then on the Board)
at a meeting of the Board called and held for such purpose (after reasonable
notice to the Executive and an opportunity for the Executive, together with
counsel, to be heard before the Board) finding that, in the good faith opinion
of the Board, the Executive engaged in conduct set forth above and specifying
the particulars thereof in reasonable detail.

                  (i) Any material adverse change in the Executive's status or
         position, including, without limitation, any material diminution in the
         Executive's position, duties, responsibilities or authority or the

         the Executive under the Bonus Plan below 50% of the Executive's Base
         Salary or a failure to pay when due any bonus earned for a completed
         performance period in accordance with the applicable bonus plan
         ("Earned Bonus"), provided however, that the Company's failure to
         actually award any bonus to the Executive, or the Company's actually
         awarding a bonus to the Executive which is less than the Target Bonus
         in each case in accordance with the applicable bonus plan, shall not
         constitute Good Reason; or

                  (iv) The breach by the Company of any of its material
         obligations under this Agreement;

                  (v) The relocation of the Company's principal executive

         by more than thirty-five (35) miles or the Company requiring the
         Executive to be based anywhere other than the Company's principal
         executive offices, except for required travel substantially consistent
         with the Executive's business obligations;

                  (vi) The Company provides the Executive a notice of
         non-renewal of the Term under Section 2(b) hereof; or

                  (vii) Jeffrey Buchalter ceases to be the Chief Executive
         Officer of the Company for any reason.

         be occupied by individuals who were neither (A) nominated by at least
         one-half (1/2) of the directors then in office (but excluding, for this
         purpose, any such individual whose initial assumption of office occurs
         as a result of either an actual or threatened election contest or other
         actual or threatened solicitation of proxies or consents by or on
         behalf of a Person (as defined herein) other than the Board) nor (B)
         appointed by directors so nominated, or

         ownership (within the meaning of Rule 13d-3 promulgated under the
         Exchange Act) of a majority of the then outstanding voting securities
         of the Company (the "Outstanding Company Voting Securities"); provided,
         however, that the following acquisitions shall not constitute a Change
         of Control: (A) any acquisition by the Company, or (B) any acquisition
         by any employee benefit plan (or related trust) sponsored or maintained
         by the Company or any corporation controlled by the Company, or (C) any

                  (iii) a consolidation of the Company with another entity or a
         merger of the Company with another entity in which neither the Company
         nor a corporation that, prior to the merger or consolidation, was a

         majority of the Outstanding Company Voting Securities immediately prior
         to such merger or consolidation; or

                  (v) a voluntary or involuntary liquidation of the Company; or

         a transaction not involving a Change of Control or a change in control
         of such subsidiary).

         Transactions in which the Executive is part of the acquiring group do
not constitute a Change of Control.

         (e) "Disabled" Defined. As used in this Agreement, the term "disabled"
means any mental or physical condition that renders the Executive unable to

in any of these cases are in his possession or under his control.

for senior management.

         (h) Notwithstanding anything else herein to the contrary, the Executive
shall not be entitled to realize or receive any termination related benefits
provided for in this Section 10, including, without limitation, all
post-termination payments and the acceleration of option or restricted stock or

and delivered to the Company a full release (reasonably satisfactory to the
Company's counsel) of all claims against the Company and its affiliates,
successors and assigns.

         (i) Nothing in this Agreement or in any other plan, award or agreement
of the Company applicable to the Executive shall result in the reduction or

vesting of options to acquire common stock and/or (iii) shares of restricted
stock and/or restricted stock units under Section 11 or (iv) any other payments
or benefits (the "Total Payments") that may be deemed to be contingent upon a
change in ownership or control pursuant to Section 280G of the Internal Revenue
Code ("Code"), regardless of whether the Total Payments would be subject to the
excise tax imposed by Section 4999 of the Code. If the Executive does become
liable for any excise tax under Section 4999 of the Code, such liability shall
not entitle the Executive to any additional payments from the Company to
reimburse the Executive for such tax liability. The Company shall be entitled to
withhold from payments due to the Executive an amount equal to the actual amount
of any excise tax under Section 4999 of the Code to which the Executive is
subject, as determined by the Company's independent auditors.

         (j) If and when during the Term, the Company shall adopt (or amend) a
severance plan generally applicable to its executive officers (other than the
Chief Executive Officer), which provides for payments and benefits upon certain
events of termination of employment in connection with a change in control of
the Company at levels that are greater than those provided herein under Section
10(f) or 10(i) (or provide in connection with a change in control of the
Company, for lump sum or otherwise more accelerated payments than those provided
for under Section 10(f)), then promptly following adoption (or amendment) of
such a plan, the Company and Executive agree to negotiate in good faith an
amendment to the provisions of Sections 10(f) or 10(i) to provide Executive with
comparable payments and benefits upon certain events of termination or otherwise
in connection with a change of control of the Company to those provided to other
senior executive officers covered by such plan with the same line of reporting
to the Chief Executive Officer as Executive. Notwithstanding the foregoing, it
is understood that the Company may enter into individual contractual
arrangements with other executives for benefits, and nothing herein shall
require the Company to provide the same benefits or level of benefits to the
Executive.

         11. Effect of Change of Control. In the event of a Change of Control,
in addition to any other consequences provided for in this Agreement:

         (a) all shares of restricted stock and restricted stock units awarded
to the Executive shall fully vest immediately prior to the Change of Control;
and

         (b) all options to acquire shares of common stock of the Company held
by the Executive shall become fully vested immediately prior to the effective
date of the Change of Control.

         The Executive shall have a reasonable opportunity to exercise all or
any portion of such options prior to the effective date of the Change of
Control, and any options not exercised prior to the effective date of the Change
of Control shall terminate as of the effective date of the Change of Control and
will be of no further force or effect. To the extent that this Section 11 is
inconsistent with the provisions of the relevant plan and granting instruments
under which such options were issued, the Company and the Executive agree that
such inconsistent provisions are hereby superceded and the provisions of this
Section 11 shall govern.

         12. Miscellaneous.

         (a) Entire Agreement. This Agreement (including the exhibits, schedules
and other documents referred to herein) contains the entire understanding
between the parties hereto with respect to the subject matter hereof and
supersedes any prior understandings, agreements or representations, written or
oral, relating to the subject matter hereof.

         (b) Counterparts. This Agreement may be executed in separate
counterparts, each of which will be an original and all of which taken together
shall constitute one and the same agreement, and any party hereto may execute
this Agreement by signing any such counterpart.

         (c) Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a 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 under any applicable law or rule, the validity,
legality and enforceability of the other provision of this Agreement will not be
affected or impaired thereby.

         (d) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective heirs, personal
representatives and, to the extent permitted by subsection (e), successors and
assigns. The Company will require its successors to expressly assume its
obligations under this Agreement.

         (e) Assignability. Neither this Agreement nor any right, remedy,
obligation or liability arising hereunder or by reason hereof shall be
assignable (including by operation of law) by either party without the prior
written consent of the other party to this Agreement, except that the Company
may, without the consent of the Executive, assign its rights and obligations
under this Agreement to any corporation, firm or other business entity with or
into which the Company may merge or consolidate, or to which the Company may
sell or transfer all or substantially all of its assets, or of which 50% or more
of the equity investment and of the voting control is owned, directly or
indirectly, by, or is under common ownership with, the Company. After any such
assignment by the Company, and provided that such assignment arises by operation
of law or involves an express written assumption by the assignee, the Company
shall be immediately released and discharged from all further liability
hereunder and such assignee shall thereafter be deemed to be the Company for the
purposes of all provisions of this Agreement.

         (f) Modification, Amendment, Waiver or Termination. No provision of
this Agreement may be modified, amended, waived or terminated except by an
instrument in writing signed by the parties to this Agreement. No course of
dealing between the parties will modify, amend, waive or terminate any provision
of this Agreement or any rights or obligations of any party under or by reason
of this Agreement. No delay on the part of the Company in exercising any right
hereunder shall operate as a waiver of such right. No waiver, express or
implied, by the Company of any right or any breach by the Executive shall
constitute a waiver of any other right or breach by the Executive.

         (g) Notices. All notices, consents, requests, instructions, approvals
or other communications provided for herein shall be in writing and delivered by
personal delivery, overnight courier, mail, electronic facsimile or e-mail
addressed to the receiving party at the address set forth herein. All such

reference purposes only and shall not in any way affect the meaning or
interpretation of this Agreement.

         (i) Governing Law. ALL MATTERS RELATING TO THE INTERPRETATION,

         (j) Resolution of Certain Claims - Injunctive Relief. The Executive

Accordingly, the Executive agrees that, in addition to, but not to the exclusion
of any other available remedy, the Company shall have the right to enforce the
provisions of Sections 5 through 8 or 9(f) by applying for and obtaining
temporary and permanent restraining orders or injunctions from a court of
competent jurisdiction without the necessity of filing a bond therefor, and
without the necessity of proving actual damages, and the Company shall be
entitled to recover from the Executive its reasonable attorneys' fees and costs
in enforcing the provisions of Sections 5 through 8 or 9(f).

         (k) Third-Party Benefit. Nothing in this Agreement, express or implied,
is intended to confer upon any other person any rights, remedies, obligations or
liabilities of any nature whatsoever.

         (l) Withholding Taxes. The Company may withhold from any benefits
payable under this Agreement all federal, state, city or other taxes as shall be
required pursuant to any law or governmental regulation or ruling.

         (m) Survival. The provisions of Section 4(c), 4(i) and Section 10 shall
survive the termination of the Executive's employment and the termination of the
Agreement.

         (m) Counterparts. This agreement may be executed in separate
counterparts, all of which taken together shall constitute one and the same
agreement.
