ASSIGNMENT AND TRANSFER

OF RIGHTS AND TECHNOLOGY

2.1 Assignment of Intellectual Property Rights and Agreements. Subject to the
terms and conditions of this Agreement (including without limitation full
payment under Article VII and the execution of the Ceregene Consent), CGI hereby
sells, assigns, and transfers to GBP the following:

(a) all right, title and interest in and to the Acquired IP;

(b) the SALK Agreement, subject to the terms and conditions of the SALK
Agreement; and

(c) the Out-Licenses, subject to the terms and conditions of each Out-License;
provided however, that with respect to the Ceregene Agreement, CGI hereby sells,
assigns, and transfers to GBP only those portions of the Ceregene Agreement as
they relate to the Part II Patent Rights.

For the avoidance of doubt, upon the assignment and conveyance of the
Out-Licenses and the SALK Agreement to GBP, GBP shall replace CGI as a party to
each Out-License and the SALK Agreement and shall succeed to all of the rights
and assume all of the responsibilities of CGI under each such Out-License and
the SALK Agreement as of the Effective Date, except that, with respect to the
Ceregene Agreement, GBP shall only succeed to the rights and assume the
responsibilities of CGI as they relate to the Part II Patent Rights. GBP
acknowledges and agrees that, as of and after the Effective Date, CGI shall have
no further duties or obligations under the Out-Licenses (or the applicable
portion of the Ceregene Agreement) or the SALK Agreement, and GBP shall assume
and be solely responsible for all such duties and obligations on a forward going
basis.

2.2 Transfer of Technology. In connection with the assignment described in
Section ý2.1, CGI shall provide and/or deliver to GBP:

(a) as soon as commercially practical after the Effective Date, but in any event
no later than thirty (30) days after the Effective Date, a one-time provision of
the Provided Technology. In connection with the foregoing and upon delivery, CGI
grants to GBP a perpetual, unrestricted, non-exclusive, royalty-free license
(with the right to grant sublicenses) to CGI’s Copyrights and Trade Secrets in
and to the Provided Technology. For the avoidance of doubt, the transfer of
Provided Technology shall not include the transfer of any Intellectual Property
Rights in addition to the Acquired IP; and

(b) during the six (6) month period after the Effective Date, CGI shall, upon
reasonable request by GBP or its designee, provide to GBP or its designee up to
a maximum of twenty (20) hours of e-mail and telephone support, without further
charge, to answer questions and provide advice and expertise related to the
Out-Licenses, Provided Technology and the Technology covered by the Acquired IP
and the SALK IP Rights. The estimated fair market value of such support services
is USD$105 per hour. If GBP or its designee require more than the twenty
(20) hour maximum of e-mail and telephone support during the six (6) month
period or require any such support after that period, then the Parties will
enter into good faith negotiations for a separate services agreement for such
support at commercially reasonable terms.

2.3 No Assumption of Past Liabilities. Notwithstanding anything herein to the
contrary, GBP shall not assume any liability of CGI relating to any fact,
circumstance, occurrence, condition, act, event or omission occurring, or the
underlying cause of which occurred, prior to the Effective Date, whether or not
in connection with the Acquired IP, Provided Technology, SALK Agreement or
Out-Licenses.

2.4 No Responsibility for Liabilities. Notwithstanding anything herein to the
contrary, CGI shall not be responsible for and will not assume any liability of
GBP or any of its Affiliates relating to any fact, circumstance, occurrence,
condition, act, event or omission occurring, or the underlying cause of which
occurs, on or after the Effective Date, whether or not in connection with the
Acquired IP, Provided Technology, SALK Agreement or Out-Licenses.

ARTICLE III

OPTION TO GBP

3.1 Whitehead Patent Rights. Within ninety (90) days after the Effective Date
and upon written request by GBP, CGI agrees to negotiate with GBP in good faith
to grant a non-exclusive, non-transferable (except in connection with the sale
of all or substantially all of GBP’s business relating to the Whitehead Patent
Rights), royalty-bearing (only to the extent such royalties are owned under the
MIT Agreement), worldwide sublicense under the Whitehead Patent Rights to
develop, make, use, sell, offer to sell, lease and import Licensed Products in
the Licensed Field. Such license shall be free of charge to GBP, other than to
the extent of any royalty owed to the licensors under the MIT Agreement. The
license granted to GBP will only be sublicensable: (i) by GBP within the scope
of GBP’s license described above and (ii) solely to an Affiliate of GBP or Third
Parties providing services directly to GBP or for the benefit of GBP; provided
that (x) any such sublicense shall not be further sublicensable; and (y) any
such sublicense shall be subject to a written agreement with terms that are
consistent with, and no less protective of CGI or its licensors than the terms
of the sublicense granted to GBP. Furthermore, any such sublicense will contain
additional reasonable and customary terms for a license of this nature and shall
be subject to all of the terms and conditions set forth in the MIT Agreement
with respect to sublicenses.

ARTICLE IV

LICENSES TO CGI

4.1 Grant-back License. GBP hereby grants CGI and its Affiliates a fully
paid-up, non-exclusive, perpetual, non-transferable (except in connection with
the sale of all or substantially all of CGI’s business utilizing the applicable
technology), royalty-free, worldwide license under the Acquired IP and SALK IP
Rights to use any inventions or methods disclosed or claimed therein for its own
internal research and development purposes. For the avoidance of doubt, under
the foregoing license CGI and its Affiliates shall have the right to use the
Acquired IP and SALK IP Rights in order to insert nucleic acids into cancer
cells for development of cancer immunotherapies for commercialization (e.g.,
GVAX™ immunotherapies); provided that CGI shall not use the Acquired IP or SALK
IP Rights to (i) commercialize any lentiviral particle or (ii) commercially
manufacture any product.

4.2 Sublicenses. The license to CGI described in Section ý4.1 shall not include
any right to grant any sublicenses, except that CGI may grant sublicenses to its
subcontractors for the sole limited purpose of conducting activities authorized
under Section 4.1 on behalf of and for the benefit of CGI and its Affiliates. In
the event that a subcontractor is granted such rights, the subcontractor may
exercise such rights at facilities owned and operated by the subcontractor.

4.3 2A Furin Technology. Upon CGI’s written request, GBP agrees to negotiate in
good faith to license the Acquired IP to a Third Party as necessary for such
Third Party to exploit CGI’s 2A Furin technology for in vitro antibody
production.

4.4 Termination by GBP. GBP may terminate in whole or in part the license
granted pursuant to this ýArticle IV as to CGI or any Affiliate or any
sub-licensee of CGI if CGI or such Affiliate or sub-licensee is in material
breach of any provision of ýArticle IV or ýArticle VIII hereof by giving CGI
thirty (30) days prior written notice of such termination, provided, however,
that if CGI (or, if applicable, such Affiliate or sub-licensee) cures the breach
within such thirty (30) day period, then the license granted pursuant to this
ýArticle IV will remain in effect and in force as if no breach had existed.

ARTICLE V

SALK License and assume all the responsibilities of CGI thereunder without
breach thereof. There are no existing breaches or defaults by CGI or, to CGI’s
Knowledge, any other party to any of the SALK Agreement or the Out-Licenses
(except, with respect to the breach by Genetix Pharmaceuticals, Inc. of
Article 5 under the Non-Exclusive License and Sub-License Agreement between
Genetix Pharmaceuticals, Inc. and CGI, effective as of November 1, 2005), and,
to CGI’s Knowledge, no event has occurred which (with notice, lapse of time or

such agreement by any party thereto (except, with respect to Genetix
Pharmaceuticals, Inc. as noted above), or give any such party the right to
terminate, accelerate or modify any such agreement.

(e) Effect of Transaction. The consummation of the transactions contemplated by

bound by or subject to prior to the Effective Date, or (iii) the termination,
abandonment or expiration of any Acquired IP, SALK IP Rights or any Intellectual
Property Rights owned by or licensed to GBP prior to the Effective Date; in each
case of (i), (ii) and (iii), except as a result of GBP’s or its Affiliates’
agreements, licenses or other obligations existing as of the Effective Date.

be an expense of and borne solely by CGI. To the extent required by law, GBP
shall pay Taxes deducted and withheld from payments payable hereunder to the

ARTICLE VIII

CONFIDENTIAL INFORMATION

8.1 Confidentiality. Each Party acknowledges that it may obtain confidential,
non-public information under this Agreement (“Proprietary Information”) of the
other Party. The Party receiving the Proprietary Information (“Receiving Party”)
of the other Party (“Disclosing Party”) shall for ten (10) years after the
initial disclosure of the applicable Proprietary Information, keep in confidence
and trust all of the Disclosing Party’s Proprietary Information received by it.
The Receiving Party shall not use the Proprietary Information of the Disclosing
Party other than as expressly permitted under the terms of this Agreement or by
a separate written agreement. The Receiving Party shall take all reasonable
steps to prevent unauthorized disclosure or use of the Disclosing Party’s
Proprietary Information and to prevent it from falling into the public domain or
into the possession of unauthorized persons. The Receiving Party shall not
disclose Proprietary Information of the Disclosing Party to any person or entity
other than its officers, employees, consultants and permitted sublicensees, who
need access to such Proprietary Information in order to effect the intent of
this Agreement and who have entered into written confidentiality agreements

protective terms as contained herein, or to its respective attorneys, auditors
or bankers who will abide to the confidentiality provisions herein. The
Receiving Party shall immediately give notice to the Disclosing Party of any
unauthorized use or disclosure of Disclosing Party’s Proprietary Information.
Without in any way limiting the Disclosing Party’s rights, in law or equity,
against the Receiving Party or any Third Party, the Receiving Party agrees to
provide reasonable assistance to the Disclosing Party to remedy such
unauthorized use or disclosure of its Proprietary Information. For clarity, any
non-public information provided to GBP by CGI pursuant to Section 6.7 or
Section 6.8, (“Non-Public Patent Related Information”) shall be considered GBP’s
Proprietary Information after the Effective Date. For further clarity,
Non-Public Patent Related Information shall not be considered CGI’s Proprietary
Information hereunder after the Effective Date.

8.2 Exceptions. The obligations under Section 8.1 above shall not apply to the
extent that the Proprietary Information is information which:

(a) is already known to the Receiving Party without an obligation of
confidentiality at the time of disclosure (including, with respect to CGI,
Non-Public Patent Related Information), which knowledge the Receiving Party
shall have the burden of proving;

(b) is, or, through no act or failure to act of the Receiving Party, becomes
publicly known;

(c) is rightfully received by the Receiving Party from a Third Party without
restriction on disclosure;

(d) is independently developed by the Receiving Party after the Effective Date
without reference or access to the Proprietary Information of the Disclosing
Party, which independent development the Receiving Party will have the burden of
proving; or

(e) is approved for release by written authorization of the Disclosing Party.

8.3 Disclosure to Government Agencies. Nothing in this Agreement shall prevent
the Receiving Party from disclosing Proprietary Information to the extent the
Receiving Party is legally compelled to do so by any governmental investigative
or judicial agency pursuant to proceedings over which such agency has
jurisdiction; provided, however, that as soon as reasonably possible and, in any
event, prior to any such disclosure, the Receiving Party shall (a) assert the
confidential nature of the Proprietary Information to the agency; (b) if legally
permissible, immediately notify the Disclosing Party in writing of the agency’s
order or request to disclose; and (c) cooperate fully with the Disclosing Party
in protecting against any such disclosure and/or obtaining a protective order
narrowing the scope of the compelled disclosure and protecting its
confidentiality. The Receiving Party may also disclose Proprietary Information
of the Disclosing Party to the extent required under any applicable disclosure
requirements of the U.S. Securities and Exchange Commission or any other
securities exchange or market; provided, however, that the Receiving Party shall
provide prior notice of such intended disclosure to the Disclosing Party if
possible under the circumstances and shall disclose only such Proprietary
Information of the Disclosing Party as is reasonably required to be disclosed.

ARTICLE IX

INDEMNITY OBLIGATIONS; LIMITATION OF LIABILITY

9.1 Indemnification by GBP. GBP shall indemnify, defend, and hold harmless CGI
and its Affiliates and their respective directors, board members, officers,
employees, agents and independent contractors and their respective successors,
heirs and assigns against any liability, damage, loss, or expense (including
reasonable attorneys’ fees and expenses) arising from a Third Party claim
arising out of any theory of liability (including actions in the form of tort,
warranty, or strict liability and regardless of whether such action has any
factual basis) concerning:

(a) any product, process, or service made, used, sold, imported, or performed by
GBP or its Affiliates, or sublicensees pursuant to any right or license
transferred or granted to GBP under this Agreement;

(b) GBP’s material breach of its representations or warranties made herein;

(c) any act or omission of GBP or its Affiliates or sublicensees occurring on or
after the Effective Date that is a material breach of the Out-Licenses or the
SALK Agreement; and

(d) GBP’s material breach of the last paragraph of Section 2.1 or Section 6.6 of
this Agreement;

in each case (a), (b), (c) or (d), except to the extent that any such claim
results from or as a result of any misrepresentation, negligence or willful
misconduct by CGI or its Affiliates.

9.2 Indemnification by CGI. CGI shall indemnify, defend, and hold harmless GBP
and its Affiliates and their respective directors, board members, officers,
employees, agents and independent contractors and their respective successors,
heirs and assigns against any liability, damage, loss, or expense (including
reasonable attorneys’ fees and expenses) arising from a Third Party claim
arising out of any theory of liability (including actions in the form of tort,
warranty, or strict liability and regardless of whether such action has any
factual basis) concerning:

(a) any product, process, or service that is made, used, sold, imported, or
performed by CGI as a result of CGI’s exercise of its rights granted under
Article IV of this Agreement;

(b) CGI’s material breach of any of the representations or warranties made
herein; or

(c) any existing conflicts, if any, between the Out-Licenses as of the Effective
Date.

in each case (a), (b) or (c), except to the extent that any such claim results
from or as a result of any misrepresentation, acts, omissions, negligence or
willful misconduct by GBP or its Affiliates.

9.3 Procedures. In the event that any Party entitled to indemnification under
Section 9.1 or 9.2 (an “Indemnitee”) is seeking such indemnification Indemnitee
agrees to provide the indemnifying Party with prompt written notice of any
claim, suit, action, demand, or judgment for which indemnification is sought
under this Agreement. The indemnifying Party agrees, at its own expense, to
provide attorneys reasonably acceptable to Indemnitee to defend against any such
clam. The Indemnitee shall cooperate fully with the indemnifying Party in such
defense and will permit the indemnifying Party to conduct and control such
defense and the disposition of such claim, suit, or action (including all
decisions relative to litigation, appeal, and settlement); provided, however,
that any Indemnitee shall have the right to retain its own counsel if
representation of such Indemnitee by the counsel retained by the indemnifying
Party would be inappropriate because of actual or potential differences in the
interests of such Indemnitee and any other party represented by such counsel.
Such counsel retained by an Indemnitee may participate in the defense and
disposition of such claim; provided that the indemnifying Party is allowed to
conduct and control such defense and disposition. The indemnifying Party agrees
to keep the Indemnitee informed of the progress in the defense and disposition
of such claim and to consult with the Indemnitee with regard to any proposed
settlement; provided that the indemnifying Party shall not dispose of or settle
any such claim in any manner which results in an admission of liability or an
agreement to make payments by Indemnitee, or otherwise adversely affects
Indemnitee’s rights or interests, without the Indemnitee’s prior written
consent.

9.4 Limitation of Liability. EXCEPT FOR A BREACH OF Article VIII, OR WITH
RESPECT TO THE INDEMNIFICATION OBLIGATIONS UNDER Article IX, IN NO EVENT SHALL
EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, CONSEQUENTIAL,
INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES OR LOST PROFITS, HOWEVER CAUSED AND
BASED ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE) ARISING IN ANY WAY OUT
OF THIS AGREEMENT, WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES.

ARTICLE X

MISCELLANEOUS

10.1 Submission to Jurisdiction; Consent to Service of Process. Any litigation
against either Party hereto, including any to enforce any judgment entered by
any court in respect thereof, shall be brought in any federal or state court of
competent jurisdiction located in New York County in the State of New York, and
the Parties hereto hereby irrevocably submit to the exclusive jurisdiction of
any federal or state court located within New York County in the State of New
York, over any such action. The Parties hereby irrevocably waive, to the fullest
extent permitted by applicable law, any objection which they may now or
hereafter have to the laying of venue of any such action brought in such court
or any defense of inconvenient forum for the maintenance of such action. Each of
the Parties hereto agrees that a judgment in any such action may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law.

10.2 Additional Actions and Documents. Each of the Parties hereby agrees use
commercially reasonable efforts to take or cause to be taken such further
actions, to execute, acknowledge, deliver and file or cause to be executed,
acknowledged, delivered and filed such further documents and instruments, and to
use commercially reasonable efforts to obtain such consents, as may be necessary
or as may be reasonably requested to fully effectuate the purposes, terms and
conditions of this Agreement, whether at or after the Effective Date. For the
avoidance of doubt, CGI agrees to execute all documents necessary to assign to
GBP any Patents owned by CGI and included within CGI’s Patent portfolio as of
the Effective Date related to lentiviral vector technology for the compositions
and methods for making lentiviral particles that were not but should have been
included in the Acquired IP as of the Effective Date, which such Patents shall
be considered Acquired IP subject to the terms and conditions of this Agreement.

in writing and shall be deemed given (a) when delivered personally by hand (with
written confirmation of receipt); (b) when sent by facsimile (with written
confirmation of transmission); or (c) one business day following the day sent by
overnight courier (with written confirmation of receipt), in each case at the

10.4 Entire Agreement; Amendments and Waivers. This Agreement (including all
appendices, exhibits, schedules and other attachments) represents the entire
understanding and agreement between the Parties hereto with respect to the
subject matter hereof and supersedes all prior negotiations and drafts of the
Parties with regard to the transactions contemplated herein and therein. This
Agreement can be amended, supplemented or changed, and any provision hereof can
be waived, only by written instrument making specific reference to this
Agreement signed by the Party against whom enforcement of any such amendment,
supplement, modification or waiver is sought. No action or nonaction taken
pursuant to this Agreement, including without limitation, any investigation by
or on behalf of any Party, shall be deemed to constitute a waiver by the Party
taking such action or nonaction of compliance with any representation, warranty,
covenant or agreement contained herein. The waiver by any Party hereto of a
breach of any provision of this Agreement shall not operate or be construed as a
further or continuing waiver of such breach or as a waiver of any other or
subsequent breach. No failure on the part of any Party to exercise, and no delay
in exercising, any right, power or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of such right, power or remedy
by such Party preclude any other or further exercise thereof or the exercise of
any other right, power or remedy.

10.5 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York applicable to contracts made
and performed in such state, without giving effect to its principles of
conflicts of law.

10.6 Binding Effect; Assignment. This Agreement shall be binding upon and inure
to the benefit of the Parties and their respective successors and permitted
assigns. Nothing in this Agreement shall create or be deemed to create any Third
Party beneficiary rights in any Person not a party to this Agreement. No
assignment or transfer of this Agreement or of any rights or obligations
hereunder may be made by either Party, directly or indirectly (by operation of
law or otherwise), without the prior written consent of the other Party, and any
attempted assignment without the required consent shall be void; provided,
however, that either Party shall have the right to transfer or assign this
Agreement to an entity that acquires all or substantially all of business or
assets of such Party to which this Agreement relates, whether by merger,
reorganization, acquisition, sale, or otherwise, and agrees to be strictly bound
by the terms and conditions of this Agreement.

10.7 Good Faith Performance. The Parties agree to cooperate fully to work in
good faith and mutually to assist each other in the performance of this
Agreement. In this regard, the Parties will meet and consult to seek to resolve
any problems and disputes under this Agreement.

10.8 Severability. If any term or other provision of this Agreement is invalid,
illegal, or incapable of being enforced by any law or public policy, all other
terms or provisions of this Agreement shall nevertheless remain in full force
and effect so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
Party. Upon such determination that any term or other provision is invalid,
illegal, or incapable of being enforced, the Parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
Parties as closely as possible in an acceptable manner in order that the
transactions contemplated hereby are consummated as originally contemplated to
the greatest extent possible.

10.9 Counterparts; Language. This Agreement may be executed in one or more
counterparts, each of which will be deemed to be an original copy of this
Agreement and all of which, when taken together, will be deemed to constitute
one and the same agreement. This Agreement shall be drafted in English only.

10.10 No Agency. Nothing in this Agreement shall be construed as establishing a
joint venture or an agency relationship between the Parties. Neither Party shall
have, or shall represent that it has, any power, right or authority to bind the
other Party to any obligation or liability.

10.11 Rules of Construction. This Agreement shall be construed without regard to
any presumption or rule requiring construction or interpretation against the
Party drafting or causing any instrument to be drafted. The words “hereof,
“herein” and “hereunder” and words of similar import when used in this Agreement
will refer to this Agreement as a whole (including any annexes, exhibits and
schedules to this Agreement) and not to any particular provision of this
Agreement, and section and subsection references are to this Agreement unless
otherwise specified. The words “include”, “including”, or “includes” when used
herein shall be deemed in each case to be followed by the words “without
limitation” or words having similar import. The headings in this Agreement are
included for convenience of reference only and will not limit or otherwise
affect the meaning or interpretation of this Agreement. The meanings given to
terms defined herein will be equally applicable to both the singular and plural
forms of such terms.

10.12 Force Majeure. Neither Party shall be liable hereunder by reason of any
failure or delay in the performance of its obligations hereunder on account of
strikes, shortages, riots, insurrection, fires, flood, storm, explosions, acts
of God, war, governmental action, labor conditions, earthquakes, material
shortages or any other causes that are beyond the reasonable control of such
Party.
