as if such performance were carried out by LICENSEE itself, including, without limitation, the payment of any royalties or other
payments provided for hereunder, regardless of whether the terms of any sublicense provide for such amounts to be paid by the
SUBLICENSEE directly to YALE. A breach of this provision shall constitute a material breach that is subject to Article 13.1(b).

at the rate set forth in Article 6.8, within thirty (30) days of receiving notice thereof from YALE.



 


		9.3.	On or before the ninetieth (90th) day following
the close of LICENSEE’s fiscal year, LICENSEE shall provide YALE with LICENSEE’s certified financial statements for
the preceding fiscal year including, at a minimum, a balance sheet and an income statement.



 


10.         PATENT
PROTECTION


 


		10.1.	LICENSEE shall be responsible for all past, present and
future costs of filing, prosecution and maintenance of all United States patent applications and patents contained in the LICENSED
PATENTS. Any and all such United States patent applications, and resulting issued patents, shall remain the joint property of
LICENSEE and YALE.



 


		10.2.	LICENSEE shall be responsible for all past, present and
future costs of filing, prosecution and maintenance of all foreign patent applications and patents contained in the LICENSED PATENTS
in the countries outside the United States in the LICENSED TERRITORY selected by LICENSEE and agreed to in writing by YALE. All
such applications or patents shall remain the joint property of LICENSEE and YALE.



 


		10.3.	All patent applications under the LICENSED PATENTS shall
be prepared, prosecuted, filed and maintained by independent patent counsel chosen by LICENSEE. Said independent patent counsel
shall be ultimately responsible to LICENSEE. LICENSEE shall instruct patent counsel to keep both LICENSEE and YALE fully informed
of the progress of all patent applications and patents, and to give both LICENSEE and YALE reasonable opportunity to comment on
the type and scope of useful claims and the nature of supporting disclosures. YALE shall have no liability to LICENSEE for damages,
whether direct, indirect or incidental, consequential or otherwise, allegedly arising from its good faith decisions, actions and
omissions in connection with such prosecution.



 




    - 13 - 


     


    

 


		10.4.	LICENSEE will not finally abandon any LICENSED PATENT without
YALE's consent, and LICENSEE shall provide YALE with sufficient notice of its intent to abandon any LICENSED PATENT so YALE may,
at its sole discretion, continue prosecution of such LICENSED PATENT at YALE’s expense. In such circumstance, LICENSEE shall
assign all of its right, title and interest to any such LICENSED PATENT, such patent or patent application shall no longer be
a LICENSED PATENT, and YALE shall be free to issue licenses to third parties for any such LICENSED PATENT.



 


		10.5.	LICENSEE shall mark, and shall require AFFILIATES and SUBLICENSEES
to mark, all LICENSED PRODUCTS, that are tangible products, with the numbers of all patents included in LICENSED PATENTS that
cover the LICENSED PRODUCTS. Without limiting the foregoing, all LICENSED PRODUCTS shall be marked in such a manner as to conform
with the patent marking notices required by the law of any country where such LICENSED PRODUCTS are made, sold, used or shipped,
including, but not limited to, the applicable patent laws of that country.



 


11.         INFRINGEMENT
AND LITIGATION


 


		11.1.	Each party shall promptly notify the other in writing in
the event that it obtains knowledge of infringing activity by third parties, or is sued or threatened with an infringement suit,
in any country in the LICENSED TERRITORY as a result of activities that concern the LICENSED PATENTS, and shall supply the other
party with documentation of the infringing activities that it possesses.



 


		11.2.	During the TERM of this Agreement:



 


		(a)	LICENSEE shall have the first right and obligation to defend
the LICENSED PATENTS against infringement or interference in the FIELD and in the LICENSED TERRITORY by third parties. This right
and obligation includes bringing any legal action for infringement and defending any counter claim of invalidity or action of
a third party for declaratory judgment for non-infringement or non-interference. If, in the reasonable opinion of both LICENSEE’s
and YALE’s respective counsel, YALE is required to be a named party to any such suit for standing purposes, LICENSEE may
join YALE as a party; provided, however, that (i) YALE shall not be the first named party in any such action,
(ii) the pleadings and any public statements about the action shall state that the action is being pursued by LICENSEE and that
LICENSEE has joined YALE as a party; and (iii) LICENSEE shall keep YALE reasonably apprised of all developments in any such action.
LICENSEE may settle such suits solely in its own name and solely at its own expense and through counsel of its own selection;
provided, however, that no settlement shall be entered without YALE’s prior written consent, such consent
not to be unreasonably withheld. Without limiting the foregoing, YALE may withhold its consent to any settlement that would in
any manner constitute or incorporate an admission by YALE or require YALE to take or refrain from taking any action. LICENSEE
shall bear the expense of such legal actions. Except for providing reasonable assistance, at the request and expense of LICENSEE,
YALE shall have no obligation regarding the legal actions described in Article 11.2 unless required to participate by law. However,
YALE shall have the right to participate in any such action through its own counsel and at its own expense. Any recovery shall
first be applied to LICENSEE’s out of pocket expenses and second shall be applied to YALE's out of pocket expenses, including
legal fees. YALE shall recover 25% of any excess recovery over those expenses.



 




    - 14 - 


     


    

 


		(b)	In the event LICENSEE fails to initiate and pursue or participate
in the actions described in Article (a) within sixty (60) days of (a) notification of infringement from YALE or (b) the date LICENSEE
otherwise first becomes aware of an infringement, whichever is earlier, YALE may, in its sole discretion, convert the LICENSE
granted in Article 3 to a nonexclusive license, and issue licenses to third parties under the LICENSED PATENTS to make, have made,
use, sell, have sold, import, export, or practice LICENSED PRODUCTS within the FIELD in the LICENSED TERRITORY. Additionally,
YALE shall have the right to initiate legal action such as that described in Article 11.2(a) at its own expense and YALE may use
the name of LICENSEE as party plaintiff to uphold the LICENSED PATENTS. In such case, LICENSEE shall provide reasonable assistance
to YALE if requested to do so. YALE may settle such actions solely through its own counsel. Any recovery shall be retained by
YALE. YALE may terminate the LICENSE in the country where such legal action is taken.



 


		(c)	In the event LICENSEE is permanently enjoined from exercising
its LICENSE under this Agreement pursuant to an infringement action brought by a third party, or if both LICENSEE and YALE elect
not to undertake the defense or settlement of a suit alleging infringement for a period of six (6) months from notice of such
suit, then either party shall have the right to terminate this Agreement in the country where the suit was filed with respect
to the licensed patent following thirty (30) days’ written notice to the other party in accordance with the terms of Article
15.



 


		(d)	Notwithstanding the foregoing, neither LICENSEE nor YALE
shall take any action to enforce the LICENSED PATENTS, or patent rights owned by LICENSEE and which claim the LICENSED PRODUCTS,
in low or lower-middle income countries, where such action is intended to prevent the sale of LICENSED PRODUCTS in any such countries.
However, LICENSEE and/or YALE may take such action in any such country, provided that such action is intended to prevent the manufacturing
of LICENSED PRODUCTS for export to countries that are not low-income or lower-middle countries.

12.         USE
OF YALE’S NAME


 


		12.1.	LICENSEE shall not use the name “Yale” or “Yale
University,” nor any variation or adaptation thereof, nor any trademark, tradename or other designation owned by YALE, nor
the names of any of its trustees, officers, faculty, students, employees or agents, for any purpose without the prior written
consent of YALE in each instance, such consent to be granted or withheld by YALE in its sole discretion, except that LICENSEE
may state that it has licensed from YALE one or more of the patents and/or applications comprising the LICENSED PATENTS.



 


13.         TERMINATION


 


		13.1.	YALE shall have the right to terminate this Agreement upon
written notice to LICENSEE in the event LICENSEE:



 


		(a)	fails to make any payment whatsoever due and payable pursuant
to this Agreement, or any payment that may be due under other contracts with YALE (e.g. sponsored research agreements), unless
LICENSEE shall make all such payments (and all interest due on such payments under Article 6.4) within the thirty (30) day period
after receipt of written notice from YALE; or



 


		(b)	commits a material breach of any other provision of this
Agreement which is not cured (if capable of being cured) within the sixty (60) day period after receipt of written notice thereof
from YALE, or upon receipt of such notice if such breach is not capable of being cured; or



 


		(c)	fails to obtain or maintain adequate insurance as described
in Article 14.2, whereupon YALE may terminate this Agreement immediately upon written notice to LICENSEE.



 


		13.2.	This Agreement shall terminate automatically without any
notice to LICENSEE in the event LICENSEE shall cease to carry on its business or becomes INSOLVENT, or a petition in bankruptcy
is filed against LICENSEE and is consented to, acquiesced in or remains undismissed for sixty (60) days, or LICENSEE makes a general
assignment for the benefit of creditors, or a receiver is appointed for LICENSEE.



 


		13.3.	LICENSEE shall have the right to terminate this Agreement
upon written notice to YALE:



 


		(a)	at any time on six (6) months’ notice to YALE, provided
LICENSEE is not in breach and upon payment of all amounts due YALE throughout the effective date of termination; or



 


		(b)	in the event YALE commits a material breach of any of the
provisions of this Agreement and such breach is not cured (if capable of being cured) within the sixty (60) day period after receipt
of written notice thereof from LICENSEE, or upon receipt of such notice if such breach is not capable of being cured.

		13.4.	Upon termination of this Agreement, for any reason, all
rights and licenses granted to LICENSEE under the terms of this Agreement are terminated and YALE has the option, in its discretion,
to terminate any sublicense granted by LICENSEE. Upon such termination, LICENSEE shall cease to make, have made, use, sell, have
sold, distribute, practice, import or export LICENSED PRODUCTS. Within sixty (60) days of the effective date of termination LICENSEE
shall return to YALE:



 


		(a)	All materials relating to or containing the LICENSED PATENTS,
LICENSED PRODUCTS or CONFIDENTIAL INFORMATION disclosed by YALE;



 


		(b)	the last report required under Article 4 or Article 9;
and



 


		(c)	all payments incurred up to the effective date of termination.



 


		13.5.	Termination of this Agreement shall not affect any rights
or obligations accrued prior to the effective date of such termination and specifically LICENSEE’s obligation to pay all
royalties and other payments specified by Article 4 and Article 6. In particular, but without limitation, the following provisions
shall survive any termination: Articles 2 and 8, the preservation and inspection obligations of Article 9, Article 12, this Article
13.5, Article 13.6, Article 13.8, Article 14, Article 15, Article 17.1, and Article 18. The parties agree that claims giving rise
to indemnification may arise after the TERM or termination of the LICENSE granted herein.



 


		13.6.	The rights provided in this Article 13 shall be in addition
and without prejudice to any other rights, whether at law or in equity, which the parties may have with respect to any default
or breach of the provisions of this Agreement.



 


		13.7.	Waiver by either party of one or more defaults or breaches
shall not deprive such party of the right to terminate because of any subsequent default or breach.



 


		13.8.	Upon termination of this Agreement for any reason other
than breach by YALE, LICENSEE shall permit YALE and its future licensees to utilize, reference and otherwise have the benefit
of all regulatory approvals of, or clinical trials or other studies conducted on, and all filings made with regulatory agencies
with respect to, the LICENSED PRODUCTS. In addition, at YALE's request, LICENSEE shall deliver to YALE within six months of such
request all records required by regulatory authorities to be maintained with respect to the sale, storage, handling, shipping
and use of the LICENSED PRODUCTS, all reimbursement approval files, all documents, data and information related to clinical trials
and other studies of LICENSED PRODUCTS, any other data, techniques, know-how and other information developed or generated that

PLAN


 


Protea Biosciences, Inc.


Commercial Development Plan


Development of a Proteomics-based Test for the Differential
Diagnosis of Malignant Melanoma 


 


Objective


To develop, validate and commercialize a proteomics mass spectrometry
imaging-based test for use in the differentiation between benign melanocytic nevi and conventional malignant melanomas.


 


Mass Spectrometry Imaging is an objective and reliable method
that may be helpful in difficult cases, in which rendering a firm diagnosis of either benign nevus or malignant melanoma may be
very difficult. The identification of protein expression profiles, which discriminate between benign melanocytic nevi and malignant
melanomas, has led to the discovery of a set of clinically useful tumor biomarkers that can be incorporated into standard diagnostic
and treatment strategies.


 


Medical Advisory Board


The Company, in collaboration with Rossitza Lazova, PhD., will
organize a Medical Advisory Board to assist in guiding and reviewing the test development plan and activities.


 


Validation Studies


Protea scientists, working with Dr. Lazova, have demonstrated
that Mass Spectrometry Imaging can effectively differentiate between benign melanocytic nevi and malignant melanomas in formalin-fixed,
paraffin-embedded tissue sections based on proteomic differences. To date a study has been completed and published that included
a total of 104 archival formalin-fixed, paraffin-embedded tissue samples from 51 histologically unequivocal banal melanocytic nevi
(BMN) and 54 conventional primary cutaneous malignant melanomas.


 


To validate the sensitivity and specificity of the test, a set
of follow on validation studies will be designed and completed that will include representative samples from multiple types of
benign melanocytic nevi, stages of malignant melanoma and matched adjacent tissue samples. The studies will include comparative
analysis via genomics test methods, including FISH and CGH, to provide comparison data with other confirmatory techniques that
are currently in use.


 


CLIA Laboratory Test


Upon completion of the validation studies, the Company will
proceed to make the test commercially available as a CLIA laboratory test. The test will be positioned for use in the approximately
33% of cases where skin biopsies are obtained and further pathologic consultation is required to establish a diagnosis. Reimbursement
will be applied for and obtained for the test and related pathologic consultation. It should be noted that codes already exist
for melanoma tests and consultations.


 




    - 24 - 


     


    

 


Follow on Development


Upon the successful commercial launch of the test, follow on
developments will be pursued by the Company as recommended by its Medical Advisors, including the potential development of melanoma
screening assays.
