pursuant to a certain 6% Promissory Notes in the aggregate principal amount of

      The Subordinated Lenders hereby consent to and approve of the execution,
delivery and performance by the Borrower of the Note and the Senior Loan

<PAGE>
                                                                               2

Documents, and the consummation of the transactions contemplated thereby
notwithstanding anything to the contrary contained in any of the Subordinated
Debt Documents. Each of the Borrower and the Subordinated Lenders represents and
warrants to the Senior Lender that there does not exist any default under the
Subordinated Note or the Subordinated Debt.

      2. Subordination.

      (a) The payment of any and all of the Subordinated Debt is hereby
expressly subordinated and made junior to the payment of the principal amount,
all interest and any other amounts due on the Senior Debt to the extent and in
the manner set forth herein.

      (b) Anything in the Subordinated Note, or in any other Subordinated Loan
Document, to the contrary notwithstanding, the Borrower shall not make and the
Subordinated Lenders shall not receive, accept or retain, any direct or indirect
payment, or prepayment on account, or any reduction (whether by way of loan,
set-off or otherwise) in respect of the principal of, premium on or interest on
the Subordinated Debt, or any security therefor, until all of the Senior Debt
shall have been paid in full.

      (c) In the event of (i) any insolvency, bankruptcy, receivership,
custodianship, liquidation, reorganization, readjustment of debt, arrangement,
composition, assignment for the benefit of creditors, or other similar
proceeding relative to the Borrower or its creditors, as such, or its property,
or (ii) any proceeding for voluntary liquidation, dissolution or other winding
up or bankruptcy proceedings, then and in any such event:

            (A) All of the Senior Debt shall first be paid in full before any
payment or distribution of any character, whether in cash, securities,
obligations or other property, shall be made in respect of the Subordinated
Debt;

            (B) Any payment or distribution of any character, whether in cash,
securities, obligations or other property, that would otherwise (but for the
terms hereof) be payable or deliverable in respect of the Subordinated Debt
(including any payment or distribution in respect of the Subordinate Debt by
reason of any other indebtedness of the Borrower being subordinated to the
Subordinated Debt), shall be paid or delivered directly to the Senior Lender, or
its representative, until all of the Senior Debt shall have been paid in full,
and the Subordinated Lenders, or any other holder of the Subordinated Debt,
irrevocably authorizes, empowers and directs all receivers, custodians,
trustees, liquidators, conservators and others having authority in the premises
to effect all such payments and deliveries;

            (C) The Subordinated Lenders will, upon the written request of the
Senior Lender, prove, enforce and endeavor to obtain payment of the aggregate
outstanding amount of all unpaid Subordinated Debt payments due and payable, or
thereafter becoming due and payable from the Borrower to the Subordinated
Lenders, and will turn over to the Senior Lender in precisely the form received,
any payment of

                                                                               3

any kind or character on account of such Subordinated Debt for application to
the payment of any indebtedness, liabilities or obligations of the Borrower to
the Senior Lender then existing. In the event that the Subordinated Lenders
shall fail to take any such action requested by the Senior Lender, the Senior
Lender may, as attorney-in-fact for the Subordinated Lenders, take such action
on behalf of the Subordinated Lenders, but for the use and benefit of the Senior
Lender. The Subordinated Lenders hereby irrevocably authorizes and empowers
(without imposing any obligation on) the Senior Lender, under the circumstances
referred to in this subparagraph (c), to demand, sue for, collect and receive
every such payment and distribution and give acquittance therefor and to file
claims and to take such other proceedings in the Senior Lender's own name or in
the name of the Subordinated Lenders or otherwise, and to vote, give consent and
take any other steps with regard thereto, all as the Senior Lender may deem
necessary or advisable for the enforcement of this Agreement, including, without
limitation, the right of the Senior Lender in its own name or in the name of the
Subordinated Lenders, to vote the full amount of the Subordinated Debt in its
sole discretion in connection with any resolution, arrangement, plan of
reorganization, compromise, settlement or extension and to take all such other
action (including, without limitation, the right to participate in any
composition of creditors' meetings for the election of trustees, acceptances of
plans and otherwise), as the Senior Lender may deem necessary or advisable for
the enforcement of this Agreement; and

            (D) The Subordinated Lenders, or any other holder of the
Subordinated Debt, shall execute and deliver to the Senior Lender or its
representative all such further instruments confirming the authorization
referred to in the foregoing clauses (B) and (C), and any powers of attorney
specifically confirming the rights of the Senior Lender arising hereunder, and
all such proofs of claim, assignments of claim and other instruments and shall
take all such other actions as may be requested by the Senior Lender or its
representative in order to enable the Senior Lender or its representative to
enforce any and all claims upon or in respect of such Subordinated Debt and to
collect and give any and all payments or distributions that may be payable or
deliverable at any time upon or with respect to such Subordinated Debt.

      (d) If, notwithstanding the provisions of this Agreement, any payment or
distribution of any character (whether in cash, securities, or other property)
or any security shall be received by the Subordinated Lenders in contravention
of the terms of this Agreement, and before all Senior Debt shall have been paid
in full, such payment, distribution or security shall not be commingled with any
asset of the Subordinated Lenders, shall be held in trust for the benefit of,
and shall be paid over or delivered or transferred to, the Senior Lender, or its
representative, for application to the payment of all Senior Debt remaining
unpaid, until all of the Senior Debt shall have been paid in full.

      (e) This Agreement, without further reference, shall pass to and may be
relied on and enforced by any transferee or subsequent holder of any Senior
Debt. In the event of any proposed sale, assignment, disposition or other
transfer of the Subordinated Debt, the Subordinated Lenders shall, prior to the
consummation of any such transfer, cause the transferee thereof to execute and
deliver to the Senior Lender an agreement (substantially identical to this
Agreement or otherwise in form and substance

<PAGE>
                                                                               4

satisfactory to the Senior Lender) providing for the continued subordination of
the Subordinated Debt to the Senior Debt as provided herein and for the
continued effectiveness of all of the rights of the Senior Lender arising under
this Agreement.

      (f) In case cash, securities or other property otherwise payable or
deliverable to the Subordinated Lenders shall have been applied pursuant to this
paragraph 2 to the payment of Senior Debt, and if the Senior Debt shall have
been paid in full, then and in such case, the Subordinated Lenders shall be
subrogated to any rights of the Senior Lender to receive any further payments or
distributions applicable to the Senior Debt, until the Subordinated Debt shall
have been paid in full. No such payments or distributions received by the
Subordinated Lenders by reason of such subrogation, of cash, securities or other
property that otherwise would be paid or distributed to the Senior Lender,
shall, as between the Borrower and its creditors other than the Senior Lender,
on the one hand, and the Subordinated Lenders on the other hand, be deemed to be
a payment by the Borrower on account of the Subordinated Debt.

      (g) Except to the extent provided in this Agreement that the Subordinated
Debt may not become due and payable or be paid, nothing contained herein shall
impair, as between the Borrower and the Subordinated Lenders, the obligation of
the Borrower, which is absolute and unconditional, to pay to the Subordinated
Lenders the principal of the Subordinated Note, and interest thereon, as and
when the same shall become due and payable in accordance with the terms thereof,
or prevent the Subordinated Lenders upon default with respect to the
Subordinated Debt, from exercising all rights, powers and remedies otherwise
provided therein or by applicable law, all subject to the rights of the holders
of Senior Debt hereunder.

      3. Priorities Relating to the Common Collateral.

      (a) Notwithstanding anything to the contrary contained in the (i)
Subordinated Note, or any other Subordinated Debt Document, or (ii) the Note or
the other Senior Loan Documents, including, without limitation, any prior
perfection of a security interest or lien under the provisions of the Uniform
Commercial Code, or any other law of any jurisdiction which is applicable, or
the existence of any present or future filing or financing statements under the
Uniform Commercial Code, or any other law of any jurisdiction which is
applicable, or in which such filing has been made, or any other recordation or
filing of any document, as between the Senior Lender and the Subordinated
Lenders, the security interests and liens now or hereafter held by the Senior
Lender pursuant to the Senior Loan Documents, or otherwise, in the Common
Collateral shall be first and prior to the security interests and liens, if any,
now or hereafter held by the Subordinated Lenders in the Common Collateral.

      (b) Subject to the other provisions of this subparagraph (b) if the Senior
Lender or the Subordinated Lenders shall, at any time, have possession or
control of any of the Common Collateral, it shall hold or control such Common
Collateral for the benefit of it and the other, as their respective interests
may appear. So long as any of the Senior Debt shall remain unpaid to the Senior
Lender, the Senior Lender may at all times, in its sole discretion, exercise any
and all powers and rights, including, without

<PAGE>
                                                                               5

limitation, the right to foreclose or otherwise realize upon the Common
Collateral that it now has or hereafter may acquire with respect to any of the
Common Collateral, whether or not in its possession, all without the necessity
of obtaining any consent or approval of the Subordinated Lenders, nor shall it
have any liability to the Subordinated Lenders for any action taken or failure
to act with respect to any such Common Collateral in its possession beyond the
exercise of reasonable care to assure the safe custody thereof. Upon payment in
full of the Senior Debt, the Senior Lender shall assign and deliver to the
Subordinated Lenders all of the Common Collateral then in its possession, but
without recourse and without any representation or warranty whatsoever.

      (c) With respect to the collection of the proceeds of any policy of
insurance, the proceeds of which are assigned to the Senior Lender or the
Subordinated Lenders pursuant to any security agreement executed and delivered
by the Borrower with the Senior Lender or the Subordinated Lenders, the Senior
Lender and the Subordinated Lenders shall join in any instructions to the
insurance companies involved so that the proceeds will be delivered to the party
entitled thereto pursuant to the terms of this Agreement.

      4. Continued Effectiveness of this Agreement.

      The terms of this Agreement, the subordination effected hereby, and the
rights of the Senior Lender and the obligations of the Subordinated Lenders
arising hereunder, shall not be affected, modified or impaired in any manner or
to any extent by: (i) any amendment, modification or termination of or
supplement to the Note, or any of the other Senior Loan Documents, or any
agreement, instrument or document executed or delivered pursuant thereto; (ii)
the validity or enforceability of any such documents; (iii) the release, sale,
exchange or surrender, in whole or in part, of any collateral security, now or
hereafter existing, for any of the Senior Debt or any other indebtedness,
liability or obligation of the Borrower to the Senior Lender, now existing or
hereafter arising; (iv) any exercise or nonexercise of any right, power or
remedy under or in respect of the Senior Debt or any of such instruments and
documents referred to in clause (i) above or arising at law; or (v) any waiver,
consent, release, indulgency, extension, renewal, modification, delay or other
action, inaction or omission in respect of the Senior Debt or any of the
agreements, instruments or documents referred to in clause (i) above or in
respect of any collateral security for the Senior Debt or any other
indebtedness, liability or obligation of the Borrower to the Senior Lender, now
existing or hereafter arising, all whether or not the Subordinated Lenders shall
have had notice or knowledge of any of the foregoing and whether or not it shall
have consented thereto.

represents and warrants to the Company as follows:
<PAGE>
            (a) The Consultant is not under any legal obligation, including any

right or claim by any third party, including, but not limited to, any of the

rights of the Company.

            7. INDEMNIFICATION. The Consultant agrees to indemnify the Company

services under this Agreement.

extent possible.

            (a) Failure or delay by either party to enforce any right which it
may have hereunder shall not be deemed to waive any right which it may have in

the laws of the State of New York applicable to agreements made and performed
wholly within such State.

                                 NEUROLOGIX INC.

                    CONFIDENTIALITY, PROPRIETARY INFORMATION

                            AND INVENTIONS AGREEMENT

            I recognize that Neurologix, Inc., a Delaware corporation
("Neurologix" and together with its subsidiaries and affiliates, the "Company"),
is engaged in a continuous program of research, development, design and
production respecting its business, present and future, specifically concerning
human gene therapy using adenovirus and adeno-associated virus vectors in the
nervous system (the "Field").

            I understand that as part of my performance of duties as an
employee, consultant, independent contractor or scientific advisory board member
of the Company (the "Engagement"), I will have access to confidential or
proprietary information of the Company, and I am (or may be) expected to make
new contributions and inventions of value to the Company. I further understand
that my Engagement creates in me a duty of trust and confidentiality to the
Company with respect to any information: (1) related, applicable or useful to
the business of the Company, including the Company's anticipated research and
development; (2) resulting from tasks assigned to me by the Company; (3)
resulting from the use of equipment, supplies or facilities owned, leased or
contracted for by the Company; or (4) related, applicable or useful to the
business of any partner, client or customer of the Company, which may be made
known to me or learned by me during the period of my Engagement.

            As part of the consideration for my Engagement or continued
Engagement, as the case may be, and the compensation received by me from
Neurologix from time to time, I hereby agree as follows:

            1. ASSIGNMENT OF PROPRIETARY INFORMATION AND INVENTIONS. All
Proprietary Information (as defined on EXHIBIT A hereto) and Inventions (as
defined on EXHIBIT A hereto) related to the Field shall be the sole property of
the Company and its assigns, and the Company and its assigns shall be the sole
owner of all patents, trademarks, service marks, copyrights and other rights
(collectively referred to herein as "Rights") pertaining to Proprietary
Information and Inventions; provided, however, that the Company shall not be
entitled by reason of this Agreement to Rights to Proprietary Information or
Inventions which are known to or developed by me outside the course of my
Engagement and/or in which the academic institution with which I am affiliated
claims rights by reason of agreements entered into by me or of applicable
policies of such academic institution. I hereby assign to the Company any rights
I may have or acquire in Proprietary Information or Inventions or Rights
pertaining to the Proprietary Information or Inventions which Rights arise in
the course of my Engagement. I further agree as to all Proprietary Information
or Inventions to which Rights arise in the course of my Engagement to assist the
Company or any person designated by it in every proper way (but at the Company's
expense) to obtain and from time to time enforce Rights relating to said
<PAGE>
Proprietary Information or Inventions in any and all countries. I will execute
all documents for use in applying for, obtaining and enforcing such Rights on
such Proprietary Information or Inventions as the Company may desire, together
with any assignments thereof to the Company or persons designated by it. My
obligation to assist the Company or any person designated by it in obtaining and
enforcing Rights relating to Proprietary Information or Inventions shall
continue beyond the cessation of my Engagement ("Cessation of my Engagement R).
In the event the Company is unable, after reasonable effort, to secure my
signature on any document or documents needed to apply for or enforce any Right
relating to Proprietary Information or to an Invention, whether because of my
physical or mental incapacity or for any other reason whatsoever, I hereby
irrevocably designate and appoint Neurologix its duly authorized officers and
agents as my agents and attorneys-in-fact to act for and in my behalf and stead
in the execution and filing of any such application and in furthering the
application for and enforcement of Rights with the same legal force and effect
as if such acts were performed by me. I hereby acknowledge that all original
works of authorship that are made by me (solely or jointly with others) within
the scope of my Engagement and which are protectable by copyright are "works for
hire" as that term is defined in the United States Copyright Act (17 USCA,
Section 101).

            2. DISCLOSURE OF POTENTIAL INVENTIONS. To the fullest extent not
prohibited under any agreement in place on the date hereof between me and any
educational institution concerning the Field (as defined in the Consulting
Agreement between me and Neurologix dated as of even date herewith), I will
promptly disclose to Neurologix all discoveries, developments, designs,
improvements, inventions, formulas, software programs, processes, techniques,
know-how, negative know-how, writing, graphic and other data concerning the
Field, whether or not patentable or registrable under patent, copyright or
similar statutes, made, discovered, conceived, begun, reduced to practice or
learned by me, either alone or jointly with others during the period and in the
course of my Engagement, for the purpose of permitting the Company to determine
whether they constitute Inventions. In order to facilitate the complete and
accurate disclosures described above, I agree to maintain complete written
records of all Inventions and of all work, study and investigation done by me in
the course of my Engagement.

            3. CONFIDENTIALITY. At all times, both during my Engagement and
after the Cessation of my Engagement, whether the cessation is voluntary or
involuntary, for any reason or no reason, or by disability, I will keep in
strictest confidence and trust all Proprietary Information, and I will not
disclose or use or permit the use or disclosure of any Proprietary Information
or Rights pertaining to Proprietary Information, or anything related thereto,
without the prior written consent of Neurologix, except as may be necessary in
the ordinary course of performing my duties for the Company. I recognize 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. I agree that I owe the Company and such third parties,
during my Engagement and thereafter, a duty to hold all such confidential or
proprietary information in the strictest confidence, and I will not disclose or
use or permit the use or disclosure of any such confidential or proprietary
information without the prior written consent of Neurologix, except as may be
necessary in the ordinary course of performing my duties for the Company
consistent with the Company's agreement with such third party.
<PAGE>
            4. NONCOMPETITION AND NONSOLICITATION. During my Engagement, and for
a period of one (1) year after the Cessation of my Engagement, I will not
directly or indirectly, whether alone or in concert with others or as a partner,
officer, director, consultant, agent, employee or stockholder of any company or
commercial enterprise, directly or indirectly, engage in any activity in the
United States or Canada that the Company shall determine in good faith is or may
be in competition with the Company concerning its work in the Field. During my
Engagement and for a period of two (2) years after the Cessation of my
Engagement, I will not, either directly or indirectly, either alone or in
concert with others, solicit or encourage any employee of or consultant to the
Company to leave the Company or engage directly or indirectly in competition
with the Company in the Field. During my Engagement, I agree not to plan or
otherwise take any preliminary steps, either alone or in concert with others, to
set up or engage in any business enterprise that would be in competition with
the Company in the Field. The following shall not be deemed to be competitive
with the Company: (i) my ownership of stock, partnership interests or other
securities of any entity not in excess of two percent (2%) of any class of such
interests or securities which is publicly traded; and (ii) my continued research
engagements for academic institutions in the Field.

            5. DELIVERY OF COMPANY PROPERTY AND WORK PRODUCT. In the event of
the Cessation of my Engagement, I will deliver to the Company all devices,
records, sketches, reports, memoranda, notes, proposals, lists, correspondence,
equipment, documents, photographs, photostats, negatives, undeveloped film,
drawings, specifications, tape recordings or other electronic recordings,
programs, data and other materials or property of any nature belonging to the
Company or its clients or customers, and I will not take with me, or allow a
third party to take, any of the foregoing or any reproduction of any of the
foregoing.

            6. NO CONFLICT. I represent, warrant and covenant that my
performance of all the terms of this Agreement and the performance of my duties
for the Company does not and will not breach any agreement to keep in confidence
proprietary information acquired by me in confidence or in trust prior to my
Engagement. I have not entered into, and I agree that I will not enter into, any
agreement, either written or oral, in conflict herewith.

            7. NO USE OF CONFIDENTIAL INFORMATION. I represent, warrant and
covenant that I have not brought and will not bring with me to the Company or
use in my Engagement any materials or documents of a former employer, or any
person or entity for which I have acted as an independent contractor or
consultant, that are not generally available to the public, unless I have
obtained written authorization from any such former employer, person or firm for
their possession and use. I understand and agree that, in my service to the
Company, I am not to breach any obligation of confidentiality that I have to
former employers or other persons.

            8. EQUITABLE RELIEF. I acknowledge that irreparable injury may
result to the Company from my violation or continued violation of the terms of
this Agreement and, in such event, I expressly agree that Neurologix shall be
entitled, in addition to damages and any other remedies provided by law, to an
injunction or other equitable remedy respecting such violation or continued
violation by me.
<PAGE>
            9. TERMINATION CERTIFICATE. Upon the Cessation of my Engagement, I
agree to sign and deliver the "Termination Certificate" attached hereto as
EXHIBIT B. My failure to sign such Termination Certificate, however, shall not
affect my obligations under this Agreement.

            10. SEVERABILITY. If any provision of this Agreement shall be
determined by any court of competent jurisdiction to be unenforceable or
otherwise invalid as written, the same shall be enforced and validated to the
extent permitted by law. All provisions of this Agreement are severable, and the
unenforceability or invalidity of any single provision hereof shall not affect
the remaining provisions.

            11. TERMINATION AT WILL. Nothing in this Agreement shall obligate
Neurologix to continue to retain me as an employee, consultant, independent
contractor or otherwise if I am in breach of this Agreement or any obligation I
have to Neurologix and such breach continues for a period of fifteen (15) days
after I receive written notice from Neurologix of such breach.

            12. MISCELLANEOUS. This Agreement shall be governed by and construed
under the laws of the State of New York applied to contracts made and performed
wholly within such state. No implied waiver of any provision within this
Agreement shall arise in the absence of a waiver in writing, and no waiver with
respect to a specific circumstance, event or occasion shall be construed as a
continuing waiver as to similar circumstances, events or occasions. This
Agreement contains the sole and entire agreement and understanding between the
Company and myself with respect to the subject matter hereof and supersedes and
replaces any prior agreements to the extent any such agreement is inconsistent
herewith. This Agreement can be amended, modified, released or changed in whole
or in part only by a written agreement executed by Neurologix and myself. This
