[...***...] negotiation period,
MAYO shall have no further obligation to NILE and can freely disclose, dispose of and exploit such Future Patents and/or New Improvements.


 





3.03Reservation of Rights. The
grant of rights in Section 3.01 is subject to the government rights of the United States government, if any, in the MAYO Patents
and Know-How, and subject to MAYO’s reservation of rights to make, have made and use the MAYO Patents and Products on a royalty-free

			review and respond with its comments, if any, within (30) days of receipt of such Manuscript or
other materials. MAYO shall consider in good faith any comments submitted by NILE regarding the content thereof and shall delete
any Confidential Information of NILE that NILE requests in writing be deleted. In no event will any Confidential Information of
NILE be released in any Manuscript or other public release without NILE’s prior written approval.



 


3.05All Other Rights Reserved. Except
as granted in Section 3.01 and 3.02, or as otherwise expressly granted herein, no other license is granted by MAYO under any intellectual

3.06Confidentiality. During
the Term, and for a period of [...***...], each Party hereto agrees to keep confidential by not disclosing to any third
party any Confidential Information disclosed by one Party (the “Disclosing Party”) to the other (the “Receiving
Party”). Additionally, each Party agrees not to use, at any time following the execution of this Amended Agreement, any
Confidential Information of the other Party for its own benefit or for the benefit of any other person or entity for any purpose
other than as is necessary for complying with the terms and conditions of this Amended Agreement.


 


		(a)	Nothing contained herein shall restrict or limit the ability of either Party to provide Confidential
Information of the other Party, including, without limitation, pursuant to a demand by a government or regulatory authority or
as otherwise may be required under applicable securities or other laws or regulations, provided the Receiving Party shall provide
the Disclosing Party with prompt written notice of such requirement prior to such disclosure to allow the Disclosing Party to seek
a protective order or other remedy where time permits.  In the event that a protective order or other remedy is not obtained,
or that the Disclosing Party waives compliance with the provisions hereof, Recipient agrees to furnish only that portion of the
Confidential Information which Recipient reasonably believes is legally required to be furnished. For purposes of clarity, either
Party shall have the right to disclose the terms and conditions of this Agreement to its professional advisors and other third
parties with whom it is involved in business discussions so long as such third parties have executed written nondisclosure agreements
with the Disclosing Party. For avoidance of doubt, any violation of the obligations stated in this Section 3.06 constitutes
a material breach of this Amended Agreement.

		(b)	Notwithstanding any other provision contained in this Amended Agreement, NILE shall have the right,
without obtaining the prior written consent of MAYO, to disclose the existence of this Amended Agreement in filings made with the
any government agency such as may be required to comply with applicable securities laws and in communications to its shareholders.



 


		(c)	The Receiving Party acknowledges and agrees that all of the Disclosing Party’s Confidential
Information is owned solely by the Disclosing Party’s (or its licensors or Affiliates) and that nothing contained in this
Amended Agreement will be construed as granting any rights to the Receiving Party, by license or otherwise, to any of the Disclosing
Party’s Confidential Information, all of which rights are specifically reserved by the Disclosing Party. The Receiving Party
further agrees not to copy all or any part of the Confidential Information or any documentation related thereto except as necessary
to support the performance of the Receiving Party under this Amended Agreement and further, not to modify, adapt, translate, reverse
engineer, decompile, disassemble, or otherwise attempt to discover any additional information with respect to the Confidential
Information. NO WARRANTIES, EXPRESS OR IMPLIED, ARE MADE BY THE DISCLOSING PARTY UNDER THIS AGREEMENT WITH RESPECT TO ANY CONFIDENTIAL
INFORMATION DISCLOSED PURSUANT HERETO.



 


		(d)	The Receiving Party agrees that its obligations hereunder are necessary and reasonable to protect
the Disclosing Party’s business interests and that the unauthorized disclosure or use of the Disclosing Party’s Confidential
Information may cause irreparable harm and significant injury, the degree of which may be difficult to ascertain. The Receiving
Party further acknowledges and agrees that in the event of any actual or threatened breach of this Amended Agreement, the Disclosing
Party may have no adequate remedy at law and accordingly, that the Receiving Party may have the right to seek an immediate injunction
enjoining any breach or threatened breach of this Amended Agreement, as well as the right to pursue any and all other rights and
remedies available at law or in equity for such breach or threatened breach.



 


		(e)	This Agreement shall apply to any Confidential Information disclosed to the Receiving Party after
the Original CD-NP Effective Date and to Confidential Information disclosed earlier to the extent the parties began discussions
prior to the Effective Date.

		(f)	Upon the request of the Disclosing Party, the Receiving Party will promptly return to the Disclosing
Party or destroy (at the Disclosing Party’s option) all material embodying Confidential Information in its possession or
under its control, including all written material, software, CD’s, DVD’s or other medium on which Confidential Information
is stored and the like, and all copies and derivatives thereof. Notwithstanding the foregoing, the Receiving Party may retain in
its legal files one copy of the Confidential Information solely to support compliance with the Agreement. Notwithstanding the foregoing,
it is acknowledged that copies that reside on computer system backups will not be destroyed. Retention of information on a backup
computer system beyond the period of protection shall not relieve the Receiving Party of its non-disclosure and non-use obligations.



 


3.07Availability of Product to MAYO.
Once a Product becomes commercially available, to the extent permitted by law, NILE will provide Products to MAYO and their
Affiliates solely for it and their use for internal clinical, research and education programs in the Field at most favored nation
pricing, i.e. no more than the lowest price available to NILE’s commercial customers for the Products for use in the
Field.


 


3.08Sublicensee Actions. NILE
may enter into sublicensing agreements under the MAYO Patents and Future Patents, Know-How and New Improvements, if applicable.
NILE shall not receive, or agree to receive, anything of value in lieu of cash or equity as consideration from a third party under
a sublicense agreement without the prior written consent of MAYO. For purposes of clarity, Sublicense consideration shall not
include (a) any amounts paid to NILE specifically designated for co-development purposes, pre-clinical and clinical research and
development of the Product, (b) any amounts paid to NILE for product manufacturing, or (c) purchases of debt or equity securities
of NILE. NILE agrees that any sublicense agreement shall (i) contain provisions at least as favorable to MAYO for the protection
of MAYO’s rights and the limitation of MAYO’s liability exposure as the terms of this Amended Agreement, including
without limitation with respect to name use, limitation of liability and indemnification and development and commercialization
obligations commensurate in scope as those set forth for NILE in this Amended Agreement, (ii) to the fullest extent applicable,
contain all rights and obligations due to MAYO contained in this Amended Agreement, (iii) name MAYO as a third party beneficiary
and (iv) not permit the sublicensee to grant further sublicenses, provided, however, that a sublicensee may grant further
sublicenses with MAYO’s prior, written, express consent. NILE shall be and remain responsible for enforcing such sublicensees’
obligations under the respective sublicense agreement, and any action by a sublicensee that would, if conducted by NILE, be a
breach of this Amended Agreement, shall be deemed a breach of this Amended Agreement by NILE; provided, however, that NILE shall
have sixty (60) days after notice from MAYO of any such breach in which to cure the same. NILE shall ascertain, calculate, audit
and collect all royalties that become payable by such sublicensee hereunder and take appropriate enforcement action against such
Sublicensee for any failure to pay or to properly calculate payments. Any purported sublicense in violation of this Section 3.08
shall be void. NILE shall furnish to MAYO a true and complete copy of each sublicense agreement and each amendment thereto, within
thirty (30) days after the sublicense or amendment has been executed, which copy shall be the Confidential Information of NILE.

to the abatement provisions set forth in Section 4.05 of this Amended Agreement, in order for NILE to maintain its exclusive license,

4.06Interest. Any payment that
is not made on or before the date when due under this Amended Agreement shall accrue interest thereon from and including such date
and until but excluding the date of payment. The interest rate will be set at a per annum rate equal to LIBOR plus two per-cent

4.07Taxes. NILE is responsible
for all applicable taxes (other than net income taxes), duties, import deposits, assessments, and other governmental charges, however
designated, that are now or hereafter will be imposed by any authority in or for the Territory, based on or relating to:


 


		(a)	the Product or use of the MAYO Patents by NILE and/or NILE’s Sublicensees;

NILE shall not be responsible for any taxes arising from transactions to which MAYO or any of its Affiliates may be parties exclusive
of transactions with NILE.


 


4.08No Deductions for Taxes.
Except as otherwise stated herein, or unless otherwise agreed to in writing by MAYO and NILE, all payments to be made by NILE to

is not responsible for any payments, including income tax, required to be paid by MAYO on funds received from or on behalf of NILE.

Article 5 - Accounting and Reports


 


5.01Royalty Reports and Payments.
NILE will, after Commercialization of at least one Product, deliver to MAYO on or before July 15th and January 15th
of each calendar year a written report for the previous 6-month period (i.e. January – June and July –
December, respectively) stating, for each Product and for each country in the Territory in which there are Net Sales:


 


		(a)	the number of Products sold during the period covered by the written report;



 


		(b)	a description of all deductions from gross receipts applied to determine Net Sales;



 


		(c)	the amount of royalties due thereupon for the period covered by the written report; and



 


		(d)	the exchange rates used to calculate the royalties
due.



 


Each such report shall be accompanied by
the royalty payment due for such 6-month period in accordance with this Article 5.


 


5.02Audit Rights. NILE agrees
to maintain the Records and to require any permitted Sublicensees to maintain the Records. "Records" mean complete
and accurate records showing clearly all transactions that are relevant to any sales, costs, expenses and payments under this Amended
Agreement, to be kept in a manner consistent with generally accepted accounting principles and standard operating procedures. MAYO
shall have the right, at its expense, through a certified public accountant or like person reasonably acceptable to NILE, to examine
the records of NILE and its Sublicensees during regular business hours before the Termination or expiration of this Amended Agreement
and for three (3) years thereafter, provided that such examination shall not take place more often than once a year and shall be
limited to a report on the accuracy of royalty statements and payments. If the audit report for any License Year discloses an underpayment
discrepancy in royalties owed by NILE and royalties paid by NILE to MAYO that exceeds five percent (5%) of total Net Sales or Sublicense
Revenue made until the date of completion of the audit, NILE shall pay the reasonable expense of the audit and pay to MAYO the
entire amount of the discrepancy plus interest within thirty (30) days from the date upon which MAYO notified NILE of the discrepancy.
Interest shall be computed at the rate which is set forth in Section 4.06 above. Discrepancies in royalty payments for a License
Year identified by the audit report amounting to less than five percent (5%) shall be paid by the end of the calendar quarter in
which the audit was made.

6.03Disclaimer. 
MAYO HAS NOT MADE AND PRESENTLY MAKES NO PROMISES, GUARANTEES, REPRESENTATIONS OR WARRANTIES OF ANY NATURE, DIRECTLY OR
INDIRECTLY, EXPRESS OR IMPLIED, REGARDING THE MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT FOR THE PRODUCTS
OR MAYO PATENTS. THE KNOW-HOW AND MAYO PATENTS PROVIDED OR LICENSED UNDER THIS AMENDED AGREEMENT ARE PROVIDED "AS IS,"
"WITH ALL FAULTS," AND "WITH ALL DEFECTS".


 


NILE is solely responsible for determining
whether the MAYO Patents and Know-How provided or licensed hereunder have applicability or utility in NILE’s manufacturing

6.04Indemnification. 


 


		(a)	Indemnification by NILE. NILE will defend, indemnify, and hold harmless MAYO and MAYO’s
Affiliates from any and all third party claims, actions, demands, judgments, losses, costs, expenses, damages and liabilities (including
but not limited to reasonable attorneys’ fees and other out-of-pocket expenses incurred in litigation) (collectively, “Claims”),
regardless of the legal theory asserted, arising out of or connected with: (a) the use by NILE of the MAYO Patents, MAYO Future
Patents, Know-How or New Improvements, if any, furnished or licensed under this Amended Agreement; (b) the development, design,
manufacture, distribution, use, sale, or other disposition of products, including Products, by NILE or its transferees; and (c)
any act or omission of NILE, including any clinical trial funded or conducted by NILE, unless such Claims are judicially determined
to have arisen out of the negligence or willful misconduct of MAYO or its Affiliates. As used herein, MAYO and its Affiliates include

such time as the Product enters into human clinical trials. In addition, such policy will name MAYO as an additional-named insured
party.

		(b)	Indemnification by MAYO. MAYO will defend, indemnify, and hold harmless NILE and NILE’s
Affiliates from any and all third party claims, actions, demands, judgments, losses, costs, expenses, damages and liabilities (including
but not limited to reasonable attorneys’ fees and other out-of-pocket expenses incurred in litigation) (collectively, “Claims”),
regardless of the legal theory asserted, arising out of or connected with: (a) the use by MAYO of any drug products provided by
NILE pursuant hereto in any pre-clinical or clinical trial funded or conducted by MAYO, unless such Claims are judicially determined
to have arisen out of the negligence or willful misconduct of NILE or its Affiliates. As used herein, NILE and its Affiliates include
the trustees, officers, agents, and employees of NILE and its Affiliates and successors in interest. MAYO will, during the Term,
carry occurrence-based liability insurance and contractual liability, in an amount and for a time period sufficient to cover the

		(c)	Procedure. With respect to any Claim giving rise to indemnification hereunder, the indemnitee

sole control of the defense, settlement or disposition thereof, including, without limitation, the selection of defense counsel.
The indemnitee shall be required to fully cooperate with the indemnifying Party in the defense and settlement of all such Claims
at the indemnifying Party’s request and expense. If the indemnifying Party assumes any such defense, the indemnifying Party
shall not be liable for any legal or other expenses subsequently incurred directly by the indemnitee in connection with such defense.
So long as the indemnifying Party is diligently conducting the defense of the claim, (i) the indemnitee will not consent to the
entry of any judgment or enter into any settlement with respect to the Claim without the prior written consent of the indemnifying
Party, and (ii) the indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect
to the Claim without the prior written consent of the indemnitee, which consent will not be unreasonably withheld or delayed; provided,
however, that such consent of the indemnitee will not be required if the judgment or settlement contains a full release of Claims
against the indemnitee and does not contain any admission of wrongdoing by the indemnitee. Notwithstanding any other provision
of this subsection, if an indemnitee withholds its consent to a bona fide settlement offer, where but for such action the indemnifying
Party could have settled such Claim, the indemnifying Party will be required to indemnify the indemnitee only up to a maximum of
the bona fide settlement offer for which the indemnifying Party could have settled such claim.

6.05Additional Waivers. IN NO
EVENT WILL EITHER PARTY’S LIABILITY OF ANY KIND INCLUDE ANY SPECIAL, INDIRECT, INCIDENTAL, OR FUTURE DAMAGES, EVEN IF SUCH
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN NO CASE WILL MAYO’S LIABILITY OF ANY KIND EXCEED THE TOTAL
AMOUNTS WHICH HAVE ACTUALLY BEEN PAID TO MAYO BY NILE AS OF THE DATE OF FILING OF THE ACTION AGAINST MAYO WHICH RESULTS IN THE
SETTLEMENT OR AWARD OF DAMAGES.


 


Article 7 - Term and Termination


 


7.01Term.
Unless sooner terminated, this Amended Agreement shall continue in full force and effect until the later of (a) the expiration
of the last to expire Valid Claim contained in the MAYO Patents, or (b) the 20th anniversary of this Amended Agreement. Upon such
expiration, NILE shall be deemed to have a fully paid-up license to any Know-How as provided in Section 3.01 herein.


 


7.02Material Breach. MAYO shall
be entitled to terminate this Amended Agreement at any time based upon material breach if NILE has failed to cure such material
breach within [...***...] of receipt of notice by NILE from MAYO that NILE is in breach. Any such notice from MAYO shall
identify with specificity the basis for its assertion of material breach.


 


7.03Termination for Other
than Material Breach. NILE may terminate this Amended Agreement without cause upon ninety (90) days prior written notice to
MAYO.


 


7.04Termination for Challenge.
MAYO may terminate this Amended Agreement by transmitting a notice
of termination to NILE in the event NILE challenges the validity or enforceability of any of the MAYO Patents Rights in any manner;
provided, however, that notwithstanding anything contained in this Section 7.04, if NILE believes that it has the obligation
under applicable law to disclose prior art to any applicable patent authority or office, such disclosure shall not be deemed a
challenge for purposes of this Section 7.04 and MAYO shall not have the right to terminate the licenses granted pursuant to this
or any other agreement. NILE will notify MAYO of any disclosure made by it pursuant to this Section.

7.05Termination for Development
Delay. MAYO may terminate this Amended Agreement by transmitting a notice of termination to NILE in the event NILE or a Sublicensee
(a) has not initiated the next clinical trial of a CD-NP Product within [...***...] after the Effective Date of this
Amended Agreement or (b) has not initiated a clinical trial of a CU-NP Product within [...***...] after the Effective
Date of this Amended Agreement. For purposes of clarity, initiation of a clinical trial shall be deemed to have occurred when the
first person enrolled in the clinical trial has been dosed with the Product. The selection of the Product to be evaluated in the
next clinical trial shall be at the sole discretion of NILE or its Sublicensee, and the initiation of such clinical trial shall
constitute full satisfaction of NILE’S diligence obligations under this Agreement with respect to the Products. If MAYO transmits
a notice of Termination for Development Delay, then NILE shall transfer to MAYO (a) whatever rights NILE has in pre-clinical and
clinical studies related to the Products; and (b) any rights NILE may have in any active INDs related to the Products. If MAYO
fails to transmit a notice of termination to NILE to terminate this Amended Agreement and NILE then initiates a clinical trial
of a Product, then upon such initiation, MAYO’S right to terminate for a development delay shall be extinguished and of no
further force or effect.


 


7.06Insolvency of Company. MAYO
shall have the right to terminate this Amended Agreement by transmitting a notice of termination to NILE in the event NILE ceases
conducting business in the normal course, files for bankruptcy protection, makes a general assignment for the benefit of creditors,
admits in writing its inability to pay its debts as they are due, permits the appointment of a receiver for its business or assets,
or avails itself of or becomes subject to any proceeding under any statute of any governing authority relating to insolvency or
the protection of rights of creditors. In such event, NILE will provide copies (or the originals if available) of all toxicity,
efficacy and other data generated by NILE and NILE will transfer to MAYO any rights NILE may have in any active INDs related to
Products.


 


7.07Effect of Termination.
Upon termination of this Amended Agreement, all rights granted herein will
immediately revert to MAYO with no further notice or action required on MAYO’s behalf. NILE shall also transfer to MAYO
those items and rights set forth in Section 7.05(a) and (b) above and other data generated solely by NILE (including by contractors
or agents on their behalf) in the course of NILE's efforts to develop Products or obtain governmental approval for the sale of
Products, for use in connection with the development and commercialization of Products. For purposes of clarity, NILE shall not
be obligated to transfer to MAYO any rights it may have in the NILE Patents.

and distributors then have in inventory in each country or Territory. At MAYO’s election, NILE, its Sublicensees and distributors
may sell the Product in that country or Territory if NILE pays any royalties due thereon in accordance with Sections 4.03 and 5.01.

Article 9 – MAYO Patent Enforcement


 


9.01Third Party
Litigation. In the event a third party institutes a suit against NILE for patent infringement involving a Product, NILE will
promptly inform MAYO and keep MAYO regularly informed of the proceedings. In the event the third party sues or joins MAYO, NILE
will have the right to control the defense of the suit provided, however, that MAYO may be represented by counsel of its own selection,
and at its own expense. Each Party will bear its own costs of the suit and with respect to any suit defended by NILE, NILE will
be entitled to all sums recovered, after each party has been reimbursed for its respective legal fees and costs. If NILE declines
to defend the action, MAYO shall have the right to control the defense of the suit provided, however, that NILE may be represented
by counsel of its own selection, and at its own expense. With respect to any suit defended by MAYO, MAYO will be entitled to all
sums recovered, after each party has been reimbursed for its respective legal fees and costs.


 


9.02Infringement by Third Party.
NILE and MAYO will promptly inform the other Party in writing of any alleged infringement of any MAYO Patent and provide the
other Party with available evidence of such infringement, and MAYO and NILE will have the right to


institute an action for infringement of
the MAYO Patents consistent with the following:

		(a)	If MAYO and NILE agree to institute suit jointly, then the suit will be brought in the names of
both parties. NILE will exercise control over such action, provided, however, that MAYO may, if it so desires, be represented by
counsel of its own selection, and at its own expense.



 


		(b)	In the absence of an agreement to institute a suit jointly, NILE may institute suit and, at its
option, join MAYO as a plaintiff. In that event, NILE will bear the entire cost of such litigation, including attorneys' fees.
MAYO will cooperate reasonably with NILE, except financially, in such litigation. NILE will not settle or enter into a voluntary
disposition of the action without MAYO’s prior written consent, which consent shall not be unreasonably withheld.



 


		(c)	In the absence of an agreement to institute a suit jointly, and if NILE determines not to institute
a suit, as provided in paragraph (b) of this Section 9.02, then MAYO may institute suit and, at its option, join NILE as a plaintiff
in the litigation. MAYO will bear the entire cost of such litigation, including attorneys' fees. NILE will cooperate reasonably
with MAYO, except financially, in such litigation. MAYO will not settle or enter into a voluntary disposition of the action without
NILE’s prior written consent, which consent shall not be unreasonably withheld.



 


		(d)	Absent an agreement to the contrary, any recovery from any such action shall (i) first be applied
to reimburse the costs and expenses of the Party bringing the action; (ii) second, to reimburse the costs and expenses of the other
Party in connection with the action; and (c) [...***...].



 


		(e)	If either Party institutes a suit under this Section 9.02 and then decides to abandon the suit,
it will first provide timely written notice to the other Party of its intention to abandon the suit, and the other Party, if it
wishes, may continue prosecution of such suit, provided, however, that the sharing of expenses and the treatment of any recovery
in such suit will be agreed-upon separately by the Parties.



 


 9.03MAYO Patent Marking.
To the extent commercially feasible and customary in the trade, NILE
will mark all Products that are manufactured or sold under this Amended Agreement with the number of each issued patent
within the MAYO Patents and/or NILE Patents that cover such Product(s). Any such marking will be in conformance with the patent
laws and other laws of the country of manufacture or sale.

Article 10 – General Provisions


 


10.01Name Use. This Amended
Agreement does not convey any right to use any of the other Party’s names or logos other than where required by law, rule
or regulation. Neither Party may use publicly for publicity, promotion, or otherwise, any logo, name, trade name, service mark
or trademark of the other Party or its Affiliates, or any simulation, abbreviation or adaptation of the same, or the name of any
of the other Party’s employee or agent without such other Party’s prior, written, express consent other than where
required by law, rule or regulation. MAYO’s marks include, but are not limited to, the terms “MAYO®” and
“MAYO CLINIC®.” Any violation of this Section 10.01 constitutes a material breach of this Amended Agreement. Upon
execution of this Amended Agreement, representatives of the Parties shall agree upon a mutually acceptable form of disclosure that
can be utilized by either of them without obtaining the prior consent of the other Party.


 


10.02Assignment. NILE may assign
its rights and obligations under this Amended Agreement to (a) an Affiliate or (b) a third party in conjunction with an acquisition
or Change of Control; in each case without MAYO's prior written consent; provided that NILE shall remain responsible for the performance
of its assignee, the assignee agrees to assume and be bound by the provisions of this Amended Agreement in writing and NILE promptly
notifies MAYO of such assignment. MAYO's written consent, which shall not be unreasonably withheld, conditioned or delayed, shall
be required prior to any other assignment of NILE's rights or obligations hereunder. Any other purported assignment is void.


 


10.03Waiver. The failure of
a Party to complain of any default by another Party or to enforce any of such Party’s rights, no matter how long such failure
may continue, will not constitute a waiver of the Party’s rights under this Amended Agreement. The waiver by a Party of any
breach of any provision of this Amended Agreement shall not be construed as a waiver of any subsequent breach of the same or any
other provision. No part of this Amended Agreement may be waived except by the further written agreement of the Parties.


 


10.04Governing Law and Jurisdiction.
This Agreement shall be governed by and construed under the laws of the State of Delaware, without regard to its conflict of law
provisions. To the extent the substantive and procedural law of the United States would apply to this Agreement, it supersedes
the application of Delaware law.

10.12Amendments.
This Amended Agreement may not be amended or modified except by a writing signed by the Parties and identified as an amendment
to this Amended Agreement.


 


10.13Construction. The Parties
agree to all of the terms of this Amended Agreement and have had the opportunity to review it thoroughly prior to its execution.
That one Party or another may have drafted all or a part of this Amended Agreement will not cause this Amended Agreement to be
read more strictly against the drafting Party. This Amended Agreement, and any changes to it, will be interpreted on the basis
that the Parties contributed equally to the drafting of all of its parts.
