THIS UNIT PURCHASE AGREEMENT
(the “Agreement”) is entered into as of the date set forth on the signature page hereto by and among
Protea Biosciences Group, Inc., a Delaware corporation (the “Company”) and the purchasers identified
on Exhibit A on the date hereof (which purchasers are hereinafter collectively referred to as the “Purchasers”
and each individually as, a “Purchaser”).

 

BACKGROUND

 

A.           Unless
otherwise defined in this Agreement, capitalized terms used in this Agreement shall have the respective meanings ascribed to such
terms in Section 9.

 

B.           The
Company is offering (the “Offering”) Units to a limited number of persons who qualify as “accredited
investors” as defined in Rule 501 of Regulation D promulgated under the Securities Act at a price per Unit of $100,000 pursuant
to the terms set forth in the Company’s Confidential Private Placement Memorandum, dated September 2, 2014, as may be amended
and/or supplemented, from time to time (collectively, the “Memorandum”).

 

C.           Each
“Unit” shall consist of (a) 50,000 Shares of Series A Convertible Preferred Stock, par value $0.0001 per share, of
the Company (“Preferred Stock”), and (b) a Warrant to purchase 200,000 shares of common stock, par value
$0.0001 per share, of the Company (“Common Stock”) at an exercise price of $0.375 per share for a period
of 3 years following the final closing (the “Final Closing Date”) of the Offering (the “Warrant”),

 

D.           The
Units are being offered on a “reasonable efforts, all or none” basis with respect to the minimum of $2,000,000
(the “Minimum Offering Amount”), which shall be exclusive of the Conversion Amount (defined below) and
thereafter on a “reasonable efforts” basis up to the maximum of $7,000,000 (the “Maximum Offering
Amount”); provided that Laidlaw may, in its sole discretion, sell up to an additional $2,000,000 in Units
to cover over-subscriptions (the “Over-Allotment”) which amounts shall
be exclusive of the Maximum Offering Amount. In addition, the Maximum Offering Amount and Over-Allotment
shall not include (i) up to an additional $2,000,000 (the “Conversion Amount”) in Units issuable to the
holders of Convertible Promissory Notes (the “Notes”) that are convertible into Units issued in this
Offering upon the Initial Closing (defined below) of the Offering and (ii) up to an additional $1,000,000, plus, if and as applicable,
accrued unpaid interest (the “Additional Convertible Loan Amount”) in Units that may be
issued to holders in connection with the conversion of outstanding Notes upon the Initial Closing of the Offering and/or such other
investors as the Company and the Placement Agent may mutually agree upon (collectively, the “Additional Investors”).

 

E.           The
Company desires to issue and sell the Units to each Purchaser in one or more closings (each a “Closing”
and collectively the “Closings”) as set forth herein.

 

NOW, THEREFORE, in consideration
of the representations, warranties, covenants and agreements herein contained and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties, intending to be legally bound, hereby agree as follows:

 

    	1

    	 

    

 

1.           AGREEMENT
TO SELL AND PURCHASE.

 

1.1           Authorization
of Units. The board of directors of the Company (the “Board of Directors”) has authorized (i) the
sale of up to 122 Units, including the Over-Allotment and the Units issued to the holders of the Notes upon conversion of the Conversion
Amount, with each Unit consisting of (a) 50,000 shares of Preferred Stock and (b) a Warrant to purchase 200,000 shares of Common
Stock at an exercise price of $0.375 per share for a period of 3 years from the Final Closing Date hereunder; (ii) the issuance
of up to 6,100,000 shares of Preferred Stock to be included as part of the authorized Units; (iii) from and after the applicable
Closing, the reservation and issuance of such number of shares of Common Stock as shall be required to be issued upon the conversion
of the Preferred Stock, which was purchased and sold at such Closing (the “Conversion Shares”), (iv)
from and after the applicable Closing, the reservation and issuance of such number of shares of Common Stock as shall be required
to be issued upon exercise of the Warrants, which were purchased and sold at such Closing (the “Warrant Shares”).

 

1.2           Initial
Sale and Purchase of Units. Subject to the terms and conditions hereof, and in reliance upon the representations, warranties
and covenants contained herein, at the Initial Closing, the Company shall issue and sell to each Purchaser, and each Purchaser
shall purchase from the Company, the number of Units set forth opposite such Purchaser’s name on Exhibit A under the
“Initial Units” column, at a purchase price of $100,000 per Unit (subject to appropriate and proportionate adjustment
for stock dividends payable in shares of, forward or reverse stock splits and other subdivisions and combinations of, and recapitalizations
and like occurrences with respect to, the Common Stock, the “Per Unit Purchase Price”). The minimum purchase
by each Purchaser is one Unit, unless the Company and the Placement Agent agree, in their mutual discretion, to allow a Purchaser
to purchase a partial Unit.

 

1.3           Subsequent
Sales and Purchases of Common Stock. Subject to the terms and conditions hereof, and in reliance upon the representations,
warranties and covenants contained herein, at each subsequent Closing, the Company shall issue and sell to each Purchaser who is
identified as a “Subsequent Closing Purchaser” on Exhibit A, which shall be deemed amended at each such subsequent
Closing to add each such additional Purchaser (each, a “Subsequent Closing Purchaser”), and each Subsequent
Closing Purchaser shall purchase from the Company, the number Units set forth opposite such Purchaser’s name on Exhibit
A at the Per Unit Purchase Price.

 

1.4           Issuance
of Warrants. The Warrants shall be in form and substance substantially the same as the form of Warrant in Exhibit B.

 

2.           CLOSINGS,
DELIVERY AND PAYMENT.

 

2.1           Initial
Closing. Subject to the conditions set forth in Section 5 herein, the initial closing of the sale and purchase of the Units
(the “Initial Closing”), shall take place electronically on such date and at such time
as is agreed between the Company and the Placement Agent (such date the “Initial Closing Date”); upon
the earliest of (1) October 15, 2014 if the Minimum Offering Amount has not been raised, which period may be extended by the Company
and the Placement Agent in their joint discretion, without notice to or consent by prospective investors, until October 31, 2014
(collectively, the “Minimum Offering Amount Deadline”) or (2) the sale of the Maximum Offering Amount
unless the Placement Agent exercises the Greenshoe, or (3) October 31, 2014 (the “Termination Date”),
which period may be extended by the Company and Placement Agent in their joint discretion, without notice or vote by prospective
investors, to a date no later than December 31, 2014 (the “Final Termination Date”) if the Minimum Offering
Amount has been raised by the Minimum Offering Amount Deadline.  Subject to the foregoing, at
the Initial Closing, the Company must sell the minimum of 20 Units, excluding any Units issued in connection with the conversion
of the Conversion Amount, and the Company may sell up to a maximum of 122 Units, which amount shall include, (1) Units which may
be issued upon the conversion of the Conversion Amount and (2) the Over-Allotment. The Units sold at the Initial Closing are sometimes
referred to herein as “Initial Units.”

 

    	2

    	 

    

 

2.2           Subsequent
Closings. If the Minimum Offering Amount has been raised by the Minimum Amount Deadline, subject to the conditions set forth
in Section 5, each Subsequent Closing shall take place electronically on such date and at such time as is agreed between the Company
and the Placement Agent (such date the “Subsequent Closing Date”), in no event later than the Termination
Date, which date may be extended without further notice to prospective investors by the Company and
the Placement Agent, to a date no later than the Final Termination Date.  Subject to the
foregoing, at Subsequent Closings, the Company may sell up to a maximum of 122 Units less the number of Units sold in all prior
Closings, which amount shall include, (1) Units issued upon the conversion of the Conversion Amount and (2) the Over-Allotment.
The Units sold at the Subsequent Closings are sometimes referred to herein as “Subsequent Units.”

 

2.3           Delivery;
Payment. At each Closing, subject to the terms and conditions hereof, the Purchasers will deliver the full amount of the Purchase
Price in cash by wire transfer of immediately available funds in accordance with instructions attached hereto as Exhibit D,
or as the Company shall otherwise direct and the Company will deliver (1) one (1) certificate registered in such Purchaser’s
name, to purchase such number of shares of Preferred Stock included in the Units purchased by such Purchaser or Subsequent Closing
Purchaser, as the case may be, at such Closing and (2) one Warrant, registered in such Purchaser’s name to purchase such
number of Warrant Shares included in the Units purchased by such Purchaser or Subsequent Closing Purchaser, as the case may be,
at such Closing. The Company and the Placement Agent, in their mutual discretion, may allow a Purchaser to purchase a partial Unit,
in which case the Purchaser shall receive a certificate representing the appropriate number of shares of Preferred Stock included
in such partial Unit and a Warrant for the appropriate number of corresponding Warrant Shares.

 

3.           REPRESENTATIONS
AND WARRANTIES OF THE COMPANY.

 

The Company represents and
warrants to each of the Purchasers that the statements made in this Section 3, except as qualified in the disclosure schedules

delivered at the Subsequent Closing in accordance with Section 5.1.1 herein, all of which qualifications in the Schedules attached
hereto and updated Schedules delivered at the Subsequent Closing shall be deemed to be representations and warranties as if made
hereunder. The Schedules shall be arranged to correspond to the numbered paragraphs contained in this Section 3, and the disclosure
in any paragraph of the Schedules shall qualify other subsections in Section 3 only to the extent that it is readily apparent from
a reading of the disclosure that such disclosure is applicable to such other subsections. For purposes of this Section 3, “knowledge”
shall mean the personal knowledge of any of the Company’s officers or directors or what they would have known upon having
made reasonable inquiry.

as currently conducted and as currently proposed to be conducted. Each Protea Entity is duly qualified, is authorized to do business
and is in good standing as a foreign corporation in each jurisdiction listed on Schedule 3.1, each of which jurisdictions
are the only jurisdictions in which the nature of such Protea Entity’s activities and properties (both owned and leased)
makes such qualification necessary except where failure to be so qualified has not had, or could not reasonably be expected to
have, individually or in the aggregate, a material adverse effect on any of the business, properties, assets, financial condition,
results of operations, prospects or Liabilities of the Protea Entities, taken as a whole (a “Material Adverse Effect”).

of any of the shares of capital stock of any Protea Entity pursuant to its Organizational Documents or other governing documents
or any agreement or other instruments to which any Protea Entity is a party or by which it is bound. Except as set forth on Schedule
3.3.2, the issuance and sale of the Units as contemplated hereby will not obligate the Company to issue shares of Common Stock
or other securities to any other person (other than the Purchaser) and will not result in the adjustment of the exercise, conversion,
exchange or reset price of any outstanding security. There are no proxies, stockholder agreements, or any other agreements between

3.5           Shell
Company Status; SEC Reports; Financial Statements. The Company was initially formed as a “shell” company as described
in Rule 144(i)(1) under the Securities Act and as of September 2, 2011, has ceased to be a shell company. The Company has filed
all reports required to be filed by it under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
in accordance with Section 13 thereof, for the twenty-four (24) months preceding the date hereof (the foregoing materials, including
the exhibits thereto and documents incorporated by reference therein being collectively referred to herein as the “SEC
Reports”) on a timely basis or has timely filed a valid extension of such time of
filing and has filed any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the SEC
Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act and the rules and regulations
of the SEC promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports
(the “Financial Statements”) comply in all material respects with applicable accounting requirements
and the rules and regulations of the SEC with respect thereto as in effect at the time of filing. Such financial statements have
been prepared in accordance with United States generally accepted accounting principles (“GAAP”) applied
on a consistent basis during the periods involved, except as may be otherwise specified in such financial statements or the footnotes
thereto, and fairly present in all material respects the financial position of the Protea Entities as of and for the dates thereof
and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal,
immaterial, year-end audit adjustments. There is no transaction, arrangement, or other relationship between a Protea Entity and
an unconsolidated or other off balance sheet entity that is not disclosed in its financial statements that should be disclosed
in accordance with GAAP and that would be reasonably likely to have a Material Adverse Effect.

 

3.6           Absence
of Liabilities. Except as set forth on Schedule 3.6, no Protea Entity has any Liabilities that are not reflected or
disclosed in the audited financial statements of the Company for the year ended December 31, 2013 or the unaudited financial statements
of the Company for the quarters ended, respectively, June 30, 2014 and March 31, 2014. Except as set forth on Schedule 3.6, no
Protea Entity is a guarantor or indemnitor of any Liability of any other Person. Except for operating
leases for personal or real property entered into in the ordinary course of business which do not require payments of more than
$50,000 in the aggregate during any fiscal year, no Protea Entity has issued any instruments,
entered into any agreements, commitments or arrangements or incurred any obligations that would have, or would reasonably be expected
to have, the effect of providing any Protea Entity with “off balance sheet” financing.

 

3.7           Agreements;
Action.

 

3.7.1.          Disclosure.

Directors has concluded, in its good faith business judgment that the issuance of the Securities is in the best interests of the

6.           COVENANTS
OF THE PARTIES.

 

6.1           Transfer
Restrictions.

 

6.1.1.          The
Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities
other than pursuant to an effective registration statement or Rule 144 promulgated under the Securities Act, to the Company or
to an Affiliate of a Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel
selected by the transferor and reasonably acceptable to the Company, the form and substance of which shall be reasonably satisfactory
to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities
Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and
shall have the rights of a Purchaser under this Agreement.

 

6.1.2.          The
Purchaser agrees to the imprinting, so long as is required by this Section 6.1, of a legend on any of the Securities, including
the Warrant Shares, substantially in the following form:

 

[NEITHER] THIS SECURITY [NOR THE SECURITIES
INTO WHICH THIS SECURITY IS [CONVERTIBLE] [EXERCISABLE]] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION
OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED
EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR
IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES
LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE
TO THE COMPANY.

 

    	22

    	 

    

  

6.1.3.          Certificates
evidencing the shares of Preferred Stock, Conversion Shares, and Warrant Shares shall be eligible for removal of the restrictive
legend set forth in Section 6.1.2 hereof, (a) following any sale of such shares of Preferred Stock, Conversion Shares or Warrant
Shares pursuant to Rule 144, or (b) if such shares of Preferred Stock, Conversion Shares, or Warrant Shares are eligible for sale
under Rule 144, without the requirement for the Company to be in compliance with the current public information required under
Rule 144 as to such shares of Preferred Stock, Conversion Shares, and Warrant Shares and without volume or manner-of-sale restrictions,
(c) following any sale of such shares of Preferred Stock, Conversion Shares, or Warrant Shares, pursuant to the plan of distribution
in an effective registration statement (in compliance with any prospectus delivery requirements), or (d) if such legend is not
required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by
the staff of the Commission) (the “Removal Date”).  The Company shall cause its counsel to
issue a legal opinion to the Transfer Agent promptly after the Removal Date if required by the Transfer Agent to effect the removal
of the legend hereunder as permitted by applicable law then in effect. The Company agrees that following the Removal Date, it
will, no later than five (5) trading days following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate
representing shares of Common Stock or Warrant Shares, as the case may be, issued with a restrictive legend, together with any
reasonable certifications requested by the Company, the Company’s counsel or the Transfer Agent (such fifth (5th) trading
day, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser a certificate representing
such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give
instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 6. Certificates for shares
of Preferred Stock, Conversion Shares, and Warrant Shares subject to legend removal hereunder shall be transmitted by the Transfer
Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System
as directed by such Purchaser if the Transfer Agent is then a participant in such system and the Company is eligible to use such
system and as directed by such Purchaser if either (i) there is an effective registration statement permitting the resale of such
shares of Preferred Stock, Conversion Shares, or Warrant Shares by the Purchaser (and the Purchaser provides the Company or the
Company’s counsel with any requested certifications with respect to future sales of such shares) or (ii) the shares are
eligible for resale by the Purchaser under Rule 144, without the requirement for the Company to be in compliance with the current
public information required under Rule 144 as to such shares of Common Stock and Warrant Shares and without volume or manner-of-sale
restrictions.

 

6.1.4.          In
addition to any other rights available to a Purchaser, if the Company fails to deliver to a Purchaser unlegended Conversion Shares
or Warrant Shares as required pursuant to this Agreement and after the Legend Removal Date such Purchaser, or a broker on such
Purchaser’s behalf, purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction
of a sale by such Purchaser of the Conversion Shares or Warrant Shares that such Purchaser was entitled to receive from the Company
(a “Buy-In”), then the Company shall promptly pay in cash to such Purchaser (in addition to any remedies
available to or elected by such Purchaser) the amount by which (a) such Purchaser’s total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased exceeds (b) the aggregate purchase price of the Conversion Shares
or Warrant Shares delivered to the Company for reissuance as unlegended shares (which amount shall be paid as liquidated damages
and not as a penalty). For example, if a Purchaser purchases shares of Common Stock having a total purchase price of $11,000 to
cover a Buy-In with respect to Common Shares or Warrant Shares delivered to the Company for reissuance as unlegended shares having
an aggregate purchase price of $10,000, the Company shall be required to pay the Purchaser $1,000, plus interest. The Purchaser
shall provide the Company written notice indicating the amounts payable to the Purchaser in respect of the Buy-In. For purposes
of this Agreement, the “purchase price” of a (a) Conversion Share shall be the Conversion Price (as defined in the
Certificate of Designation for the Series A Preferred Stock and (B) Warrant Share shall be the Exercise Price (as defined in the
Warrants).

 

    	23

    	 

    

 

6.1.5.          In
addition to such Purchaser’s other available remedies, the Company shall pay to such Purchaser, in cash, as partial liquidated
damages and not as a penalty, for each $1,000 of Conversion Shares or Warrant Shares (based on the Conversion Price or Exercise
Price of such Conversion Shares and Warrant Shares, as the case may be) delivered for removal of the restrictive legend, $10 per
trading day (increasing to $20 per trading day five (5) trading days after such damages have begun to accrue)) for each trading
day after the fifth (5th) trading day following the Legend Removal Date until such certificate is delivered without a legend.
Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Company’s failure to deliver certificates
representing any Securities as required by the Transaction Documents, and such Purchaser shall have the right to pursue all remedies
available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

 

6.2           Furnishing
of Information; Public Information.         For so long as any Purchaser holds
any Securities, or if earlier, for a period of twenty-four (24) months following the Termination Date (or the Final Termination
Date if the Offering is extended by the Company) the Company covenants to file all annual and quarterly periodic reports with
the SEC pursuant to Section 15(d) of the Exchange Act or alternatively, if registered under Section 12(b) or 12(g) of the Exchange
Act, maintain the registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act and to timely file (or obtain
extensions in respect thereof and file within the applicable grace period) all such annual and quarterly reports required to be
filed by the Company after the date hereof pursuant to the Exchange Act. Unless the Securities owned by such Purchaser shall have
been registered for resale, if at any time during the period commencing from the date that is 6 months after the date hereof and
ending 24 months following the Termination Date (or the Final Termination Date if the Offering is extended by the Company) the
Company shall fail for any reason to satisfy the current public information requirement under Rule 144(c) (a “Public
Information Failure”) then, in addition to such Purchaser’s other available remedies, the Company shall pay
to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its
ability to sell the Securities, an amount in cash equal to two percent (2.0%) of the pro-rata portion of such Purchaser’s
Purchase Price attributable to the unsold Conversion Shares and Warrant Shares on the day of a Public Information Failure and
on every thirtieth (30th) day (prorated for periods totaling less than thirty (30) days) thereafter until the earlier of (A) the
date such Public Information Failure is cured and (B) such time that such public information is no longer required for the Purchasers
to transfer their shares of Preferred Stock, Conversion Shares and Warrant Shares pursuant to Rule 144. The payments to which
a Purchaser shall be entitled pursuant to this Section 6.2 are referred to herein as “Public Information Failure Payments”.
Public Information Failure Payments shall be paid on the earlier of (Y) the last day of the calendar month during which such Public
Information Failure Payments are incurred, and (Z) the third (3rd) business day after the event or failure giving rise to the
Public Information Failure Payments is cured. Nothing herein shall limit such Purchaser’s right to pursue actual damages
for the Public Information Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in
equity including, without limitation, a decree of specific performance and/or injunctive relief. Notwithstanding anything herein
to the contrary, the maximum payment hereunder shall not exceed twelve (12%) percent of such Purchaser’s Purchase Price.
As long as any Purchaser owns Securities, if the Company is not required to file reports pursuant to such laws, it will prepare
and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the
Purchasers to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder
of Securities may reasonably request, to the extent required from time to time to enable such person to sell such Securities without
registration under the Securities Act within the requirements of the exemption provided by Rule 144.

 

    	24

    	 

    

 

6.3           Listing
of Securities. The Company agrees, (i) if the Company applies to have the Common Stock traded on any other trading market,
it will include in such application the Conversion Shares and any Warrant Shares of each Purchaser, and will take such other action
as is necessary or desirable to cause such Conversion Shares and any Warrant Shares to be listed on such other trading market
as promptly as possible, and (ii) it will take all action reasonably necessary to continue the listing and trading of its Common
Stock on a Trading Market (as defined in the Warrant) and will comply in all material respects with the Company’s reporting,
filing and other obligations under the bylaws or rules of any such Trading Market (as defined in the Warrant).

 

6.4           Reservation
of Shares. From and after the Initial Closing and any Subsequent Closing, the Company shall at all times thereafter while
the Preferred Stock and Warrants which were purchased and sold at such Closing are outstanding maintain a reserve from its duly
authorized shares of Common Stock of a number of shares of Common Stock sufficient to allow for the issuance of Conversion Shares
and Warrant Shares, which were the subject of such Closing.

 

6.5           Replacement
of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution
therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument
under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement securities.
If a replacement certificate or instrument evidencing any securities is requested due to a mutilation thereof, the Company may
require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

 

6.6           Securities
Laws; Publicity. The Company shall by 8:30 a.m. (New York City time) on the trading day immediately, following a Closing hereunder,
file a Current Report on Form 8-K disclosing the material terms of the transactions contemplated hereby and including the Transaction
Documents as exhibits thereto to the extent required by law. The Company shall not publicly disclose the name of Purchaser, or
include the name of any Purchaser in any filing with the SEC or any regulatory agency or trading market, without the prior written
consent of Purchaser, except: (a) as required by federal securities law in connection with the filing of final Transaction Documents
(including signature pages thereto) with the SEC and (b) to the extent such disclosure is required by law, in which case the Company
shall provide the Purchaser with prior notice of such disclosure permitted under this clause (b).

 

6.7           Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation
D promulgated under the Securities Act and to provide a copy thereof, promptly upon request of the Purchaser. The Company shall
take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the
Securities for, sale to the Purchaser at the Closing under applicable securities or “Blue Sky” laws of the states
of the United States, and shall provide evidence of such actions promptly upon request of any Purchaser.

 

6.8           Equal
Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid
to any person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the
same consideration is also offered to all of the parties to the Transaction Documents.

 

    	25

    	 

    

 

6.9           Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents, the Company covenants and agrees that neither it, nor any other person acting on its behalf, will provide Purchaser
or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior
thereto Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company
understands and confirms that Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of
the Company.

 

6.10         Use
of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder for working capital purposes
and shall not use the proceeds for (a) the satisfaction of any portion of the Company’s debt (other than payment of trade

Common Stock Equivalents or (c) the settlement of any outstanding litigation.

 

6.11         Commercially

shall use their respective good faith commercially reasonable efforts to take, or cause to be taken, without any party being obligated
to incur any material internal costs or make any payment or payments to any third party or parties which, individually or in the
aggregate, are material and are not otherwise legally required to be made, all actions, and to do or cause to be done, and to
assist and cooperate with the other parties in doing, all things necessary, proper or advisable for such party to consummate and
make effective, in the most expeditious manner practicable, each Closing and the other transactions contemplated hereunder.

 

6.12        Participation
in Future Financing.

 

6.12.1         From
the date hereof until the one year anniversary of the Final Closing Date, upon any issuance by the Company, any of its Subsidiaries
(or any resulting Person due to any “Spin-Outs”) in an offering pursuant to which any of the foregoing raises gross
proceeds of at least $1,000,000 of Common Stock or Common Stock Equivalents (a “Subsequent Financing”),
each Purchaser shall have the right to participate in up to an amount of the Subsequent Financing equal to such Purchaser’s
proportionate share of the Subsequent Financing based on such Purchaser’s participation in this Offering (the “Participation
Maximum”) on the same terms, conditions and price provided for in the Subsequent Financing; provided, however, that
Purchasers shall not have the right to participate in any offering by the Company or any of its Subsidiaries of Common Stock or
Common Stock Equivalents to be issued solely to Company Investors.

 

6.12.2         At
least 10 trading days prior to the closing of the Subsequent Financing, the Company shall deliver to each Purchaser a written
notice of its intention to effect a Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask
such Purchaser if it wants to review the details of such financing (such additional notice, a “Subsequent Financing
Notice”). Upon the request of a Purchaser, and only upon a request by such Purchaser made within one trading day
following the receipt by the Purchaser of the Pre-Notice, for a Subsequent Financing Notice, the Company shall promptly, but no
later than 1 trading day after such request, deliver a Subsequent Financing Notice to such Purchaser. The Subsequent Financing
Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to
be raised thereunder and the person or persons through or with whom such Subsequent Financing is proposed to be effected and shall
include a term sheet or similar document relating thereto as an attachment.

 

    	26

    	 

    

 

6.12.3         Any
Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by not later than 5:30
p.m. (New York City time) on the 5th trading day after all of the Purchasers have received the Pre-Notice that the Purchaser is
willing to participate in the Subsequent Financing, the amount of the Purchaser’s participation, and that the Purchaser
has such funds ready, willing, and available for investment on the terms set forth in the Subsequent Financing Notice. If the
Company receives no notice from a Purchaser as of such 5th trading day, such Purchaser shall be deemed to have notified the Company
that it does not elect to participate.

 

6.12.4         If
by 5:30 p.m. (New York City time) on the 5th trading day after all of the Purchasers have received the Pre-Notice, notifications
by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause their designees to participate)
is, in the aggregate, less than the total amount of the Subsequent Financing, then the Company may effect the remaining portion
of such Subsequent Financing on the terms and with the persons set forth in the Subsequent Financing Notice.

 

6.12.5         If
by 5:30 p.m. (New York City time) on the 5th trading day after all of the Purchasers have received the Pre-Notice, the Company
receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than the aggregate amount of the
Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined below) of the Participation
Maximum. “Pro Rata Portion” means the ratio of (x) the Units purchased on the Closing Date by a Purchaser participating
under this Section 6.12 and (y) the sum of the aggregate Units purchased by all Purchasers participating under this Section 6.12.

 

6.12.6         The
Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of
participation set forth above in this Section 6.12, if the Subsequent Financing subject to the initial Subsequent Financing Notice
is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within 30 trading days after the
date of the initial Subsequent Financing Notice.

 

6.12.7         Notwithstanding
the foregoing, this Section 6.12 shall not apply in respect of issuances in connection with (i) an Exempt Issuance (as defined
in Section 6.13 below); (ii) an underwritten public offering pursuant to a registration statement filed under the Securities Act;
(iii) a joint venture or acquisition of another entity by the Company, whether by purchase of stock, merger, consolidation, purchase
of all or substantially all of the assets of such entity or otherwise; (iv) services rendered to or equipment leases of the Company.

 

6.13     Most
Favored Nation Provision.

 

6.13.1         Until
the earliest of (a) the third year anniversary of the date hereof; (b) the date that the Purchaser no longer owns any securities
sold in the Offering; or (c) the date that the Company’s shares of Common Stock are approved for uplisting to a senior U.S.
stock exchange such as The NASDAQ STOCK MARKET or the NYSE MKT, in the event that the Company issues or sells any shares of Common
Stock or any Common Stock Equivalents pursuant to which shares of Common Stock may be acquired at a price less than the $0.25
per share (subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar
transaction after the date hereof) (such lower price, the “Base Price” and such issuances, collectively,
a “Dilutive Issuance”), then the Company shall promptly issue additional shares of Common Stock to such
Purchaser, for no additional consideration, in an amount sufficient so that the pro rata portion of the Purchase Price paid by
such Purchaser hereunder attributable to the Conversion Shares then held, shall be reduced to a price (rounded to the nearest
cent) when multiplied by a fraction, of which (i) the numerator shall be the number of shares of Common Stock outstanding on a
fully diluted basis immediately prior to such Dilutive Issuance plus the number of shares of Common Stock which the aggregate
consideration received or to be received by the Company for the total number of shares of Common Stock issued pursuant to the
Dilutive Issuance would purchase at the Base Price; and (ii) the denominator shall be the number of shares of Common Stock outstanding
on a fully diluted basis immediately prior to such Dilutive Issuance plus the number of such additional shares of Common Stock
so issued in connection with the Dilutive Issuance (such adjustment, a “Dilution Adjustment”). Such
Dilution Adjustment shall be made successively whenever such an issuance is made. Notwithstanding the foregoing, this Section
6.13 shall not apply in respect of an Exempt Issuance (as herein defined). No adjustment shall be made hereunder which would require
any Purchaser to surrender any shares of Common Stock to the Company.

 

    	27

    	 

    

 

For
the purposes of this Sub-Section, Exempt Issuance shall mean the issuance of (a) shares of Common Stock or options to employees,
officers or directors of the Company pursuant to any stock or option plan duly adopted for such purpose, by a majority of the
non-employee members of the Board of Directors or a majority of the members of a committee of non-employee directors established
for such purpose (collectively, the “ESOP”) and as further qualified by the provisions set forth in
Section 6.14, (b) except as specifically provided herein, securities upon the exercise or exchange of or conversion of any Securities
issued hereunder and/or other securities exercisable or exchangeable for or convertible into shares of Common Stock issued and
outstanding on the date of this Agreement, provided that such securities have not been amended since the date of this Agreement
to increase the number of such securities or to decrease the exercise price, exchange price or conversion price of such securities
and which securities and the principal terms thereof are set forth on Schedule 3.3.2, and (c) securities issued pursuant to acquisitions
or strategic transactions approved by a majority of the disinterested directors of the Company, provided that any such issuance
shall only be to a Person (or to the equityholders of a Person) which is, itself or through its subsidiaries, an operating company
or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional
benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities
primarily for the purpose of raising capital or to an entity whose primary business is investing in securities.

 

In
addition to the rights described above, if at any time while the Purchaser holds any Securities, any anti-dilution rights existing
prior to the Initial Closing of the Offering shall be triggered causing the Company to issue additional shares of Common Stock
(the “Existing Right Issuances”), the Company shall issue to the Purchasers, on a pro rata basis,
the number of additional shares of Common Stock that shall be required so that immediately following the Existing Rights Issuance,
the Purchasers shall retain the same percentage of issued and outstanding shares of Common Stock as owned of record immediately
prior to the Existing Rights Issuance.

 

6.14         ESOP.
Unless otherwise agreed to in writing by the Placement Agent, the ESOP in addition to the terms set forth in Section 6.13, shall
be subject to the following terms and conditions. The number of shares of Common Stock to be issuable under the ESOP shall be
limited to fifteen percent (the “ESOP Threshold”) of the Company’s issued and outstanding shares of Common Stock;
as such number of shares of Common Stock underlying that percentage may be adjusted on an annual basis. The ESOP Threshold shall
include the number of shares of Common Stock underlying any issued and outstanding grants under the Company’s 2002 Equity
Incentive Plan and the total number of shares of Common Stock reserved for issuance under the Company’s 2013 Equity Incentive
Plan or any other future ESOP. Within 30 days of the Final Closing Date, executive officers and key employees shall be entitled
to receive at least seventy-five percent of the aggregate sum of any issued and outstanding grants under the ESOP and any grants
to the CEO shall not exceed twenty percent of the aggregate sum of any issued and outstanding grants under the ESOP. In this regard,
the Company shall periodically inform the Placement Agent of the status of its compliance with this Section. If the Company fails
to comply timely with the ESOP provisions, then the Company shall pay the Purchasers $50,000 for each 30 day period (or any portion
of such period) that the Company is not in compliance.

 

    	28

    	 

    

 

6.15         Board
Composition. Simultaneous with an Initial Closing or Subsequent Closing, as applicable, with respect to Units in the minimum
amount of $3,000,000 (exclusive of any amounts received from the Company Investors), the Company shall ensure that the entire
Board of Directors shall be comprised of seven directors. In the event the Company enters into a merger, acquisition, consolidation,
or similar transaction, then the Company may increase the size of its Board of Directors to eight directors.

 

Within
30 days of the Final Closing, two (2) persons (each, an “Investor Nominee”) nominated by the Placement
Agent, shall have been approved for seats on the Board of Directors. To this end, the Board of Directors may during such 30-day
period, reject each Investor Nominee once so long as there is a valid business reason. To be free from doubt, if Investor Nominee
#1 for Board seat # 1 is rejected, then Investor Nominee #2 for Board seat #1 will be automatically accepted for Board seat #1
during such 30 day period.

 

6.16         Information
Statement. The Company will use its best efforts to file with the SEC by no later than September 15, 2014 an Information Statement
that is fully compliant with Regulation 14C promulgated under the Exchange Act including, but not limited to the authorization
to effectuate an amendment of its Certificate of Incorporation to increase the amount of authorized shares of Common Stock so
that the Company has sufficient shares of Common Stock available for the Offering and any contemplated capital raises by the Company.
The Company shall use its best efforts to cause the Information Statement to be delivered to the Company’s shareholders
and file the certificate of amendment of the Certificate of Incorporation with respect to the increase in Common Stock as soon
as practicable thereafter in accordance with the Exchange Act and the regulations promulgated thereunder and Delaware law.

under the Securities Act, the Exchange Act, or similar securities law, or any other Requirements of Law or otherwise, which relate
directly or indirectly to the registration, purchase, sale or ownership of any securities of the Company or to any fiduciary obligation
owed with respect thereto), including, without limitation, in connection with any action or claim relating to any action taken
or omitted to be taken or alleged to have been taken or omitted to have been taken by such Indemnified Party as a security holder;
provided that the Company shall not be obligated to indemnify or hold harmless any Indemnified Party under this Section 7.1.4
against any Indemnified Losses resulting from or arising out of any such action or claim if it has been adjudicated by a final
and non-appealable determination of a court or other trier of fact of competent jurisdiction that such Indemnified Losses were
the result of (a) a breach of such Indemnified Party’s fiduciary duty, (b) any action or omission made by the Indemnified
Party in bad faith, (c) such Indemnified Party’s willful misconduct, or (d) any criminal action on the part of such Indemnified
Party.

Rights Agreement.

3.          Automatic
Registration.

 

(a)          On
or prior to the Filing Date, the Company shall prepare and file with the Commission a registration statement (the “Automatic
Registration Statement”) covering the resale of (1) all of the Registrable Securities and (2) the Existing Registrable
Securities for an offering to be made on a continuous basis pursuant to Rule 415. In addition, the Company agrees that it will
not file any other registration statement that does not include all of the Registrable Securities prior to the Filing Deadline.
The Automatic Registration Statement required hereunder shall be on Form S-1 or Form S-3, as applicable, and shall contain substantially
the “Plan of Distribution” attached hereto as Annex A.  Subject to the terms of this Agreement, the Company
shall use its reasonable best efforts to cause the Automatic Registration Statement to be declared effective under the Securities
Act as promptly as possible after the filing thereof, but in any event not later than the Effectiveness Date, and shall use its
best efforts to keep the Automatic Registration Statement continuously effective under the Securities Act until the earlier of
the date when all Registrable Securities covered by the Registration Statement have been sold thereunder or pursuant to Rule 144
(the “Effectiveness Period”). The maximum amount of Registrable Securities or Existing Registrable Securities
that may be included in the Automatic Registration Statement at any one time shall be limited by Rule 415 or as may otherwise be
required by the Commission. In the event that there is a limitation by the Commission on the number of Registrable Securities or
Existing Registrable Securities that may be included for registration on the Automatic Registration Statements at one time, the
removal of the securities shall be applied, first to, the Existing Registrable Securities on a pro rata basis then, to any Registrable
Securities on a pro rata basis (the “Order of Cutback”). In the event, any Registrable Securities shall
be removed from the Registration Statement, the Company shall promptly advise any Investor holding such Registrable Securities
and use its best efforts to file an additional Automatic Registration Statement covering such ineligible Registrable Securities,
on a pro-rata basis, within 30 days of the date such securities become eligible for registration, which date shall be determined
by the Commission, and shall use its best efforts to cause such Automatic Registration Statement to be declared effective by the
Commission as soon as reasonably practicable. In addition, if following the initial filing of the Automatic Registration Statement,
the Placement Agent reasonably determines for any reason, after consultation with the Company, that the offering which is subject
to the Automatic Registration Statement needs to be cut back then the Placement Agent may cut back the number of Registrable Securities
or Existing Registrable Securities subject to the Automatic Registration Statement in accordance with the Order of Cutback. As
of the date of the Closing, the Placement Agent does not intend to reduce the number of Existing Registrable Securities anticipated
to be included in the Automatic Registration Statement.

 

(b)          At
any time after the Automatic Registration Statement has become effective, the Company may, upon giving prompt written notice of
such action to the Investor, suspend the use of any such Automatic Registration Statement if, in the good faith judgment of the
Company, the use of the Automatic Registration Statement covering the Registrable Securities would be detrimental to the Company
or its stockholders at such time and the Company concludes, as a result, that it is in the best interests of the Company or its
stockholders to suspend the use of such Automatic Registration Statement at such time. The Company shall have the right to suspend
such Automatic Registration Statement for a period of not more than thirty (30) consecutive days from the date the Company notifies
the Investor of such suspension, with such suspension not to exceed an aggregate of sixty (60) days (whether or not consecutive)
during any 12-month period. In the case of the suspension of any effective Automatic Registration Statement, the Investor, immediately
upon receipt of notice thereof from the Company, will discontinue any sales of Registrable Securities pursuant to such Registration
Statement until advised in writing by the Company that the use of such Automatic Registration Statement may be resumed.

(c)          If:
(i) the Automatic Registration Statement is not filed on or prior to its Filing Date (if the Company files the Automatic Registration
Statement without affording the Investor Representative the opportunity to review and comment on the same as required by Section
5(a) herein, the Company shall be deemed to have not satisfied this clause (i)), (ii) a Registration Statement registering for
resale all of the Registrable Securities is not declared effective by the Commission by the Effectiveness Date (unless the reason
for such non-registration of all or any portion of the Registrable Securities is as a result of SEC Guidance under Rule 415 or
similar rule which limits the number of Registrable Securities which may be included in a registration statement with respect to
the Investors), or (iii) after the effective date of a Registration Statement, and during the Effectiveness Period, such Registration
Statement ceases for any reason to remain continuously effective as to all Registrable Securities included in such Registration
Statement, or the Investors are otherwise not permitted to utilize the prospectus therein to resell such Registrable Securities,
for more than ten (10) consecutive calendar days or more than an aggregate of fifteen (15) calendar days (which need not be consecutive
calendar days) during any 12-month period (any such failure or breach being referred to as an “Event”,
and for purposes of clause (i), the date on which such Event occurs, and for purpose of clause (iii) the date on which such ten
(10) or fifteen (15) calendar day period, as applicable, is exceeded being referred to as an “Event Date”),
then, in addition to any other rights the Investors may have hereunder or under applicable law, on each thirty (30) day anniversary
of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the
Company shall pay to each Investor an amount in cash, as partial liquidated damages and not as a penalty, equal to 1.0% of the
aggregate purchase price paid by such Investor pursuant to the Subscription Agreement and Purchase Agreement. The parties agree
that the maximum aggregate liquidated damages payable to an Investor under this Agreement in connection with any Event or combination
of Events, shall be 6% of the aggregate Purchase Price paid by such Investor pursuant to the Purchase Agreement. If the Company
fails to pay any partial liquidated damages pursuant to this Section in full within seven days after the date payable, the Company
will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by applicable
law) to the Investor, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest
thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro rata basis for
any portion of a thirty (30) day period prior to the cure of an Event. Notwithstanding the foregoing, no payments shall be owed
with respect to any period during which all of the holder’s Registrable Shares may be sold by such holder under Rule 144
without volume or manner-of-sale restrictions; provided that the Company is in compliance with any current public information requirements
applicable to it under Rule 144.

  

4.          Piggyback
Registrations.

 

(a)          With
respect to any Registrable Securities not otherwise included in the Automatic Registration Statement or any other Registration
Statement as a result of any limitation imposed by the Commission under Rule 415 (the “Excluded Registrable Securities”),
whenever the Company proposes to register (including, for this purpose, a registration effected by the Company for other shareholders)
any of its securities under the Securities Act (other than pursuant to (i) an Automatic Registration pursuant to Section 3 hereof
or (ii) registration pursuant to a registration statement on Form S-4 or S-8 or any successor forms thereto), and the registration
form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”),
the Company will give written notice to the holder of Excluded Registrable Securities of its intention to effect such a registration
and will, subject to the provisions of Subsection 4(b) hereof, include in such registration all Excluded Registrable Securities
with respect to which the Company has received a written request for inclusion therein within twenty (20) days after the receipt
of the Company’s notice.

 

(b)          If
a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s securities, and
the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included
in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the
offering, the Company will include in such registration a pro rata share of Excluded Registrable Securities requested to be included
in such Registration Statement as calculated by dividing the number of Excluded Registrable Securities requested to be included
in such Registration Statement by the number of the Company’s securities requested to be included in such Registration Statement
by all selling security holders. In such event, the holder of Excluded Registrable Securities shall continue to have registration
rights under this Agreement with respect to any Excluded Registrable Securities not so included in such Registration Statement.

 

    	6

    	 

    

 

(c)          Notwithstanding
the foregoing, if, at any time after giving a notice of Piggyback Registration and prior to the effective date of the Registration
Statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration
of such securities, the Company may, at its election, give written notice of such determination to each record holder of Excluded
Registrable Securities and, following such notice, (i) in the case of a determination not to register, shall be relieved of its
obligation to register any Excluded Registrable Securities in connection with such registration, and (ii) in the case of determination
to delay registering, shall be permitted to delay registering any Excluded Registrable Securities for the same period as the delay
in registering such other securities.

 

5.          Registration
Procedures. If and whenever the Company is required to affect the registration of any Registrable Securities under the terms
herein, the Company will:

 

(a)          
not less than five (5) business days prior to the filing of each Registration Statement and not less than one (1) business day
prior to the filing of any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated
or deemed to be incorporated therein by reference), (i) furnish to each seller of Registrable Securities, copies of all such documents
proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject
to the review of such sellers, and (ii) cause its officers and directors, counsel and independent registered public accountants
to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each seller of Registrable
Securities, to conduct a reasonable investigation within the meaning of the Securities Act. Notwithstanding the above, the Company
shall not be obligated to provide each seller of Registrable Securities advance copies of any universal shelf registration statement
registering securities in addition to those required hereunder, or any Prospectus prepared thereto;  

 

(b)          prepare
and file with the Commission the Registration Statement with respect to such securities and use its best efforts to cause such
Registration Statement to become effective in an expeditious manner;

 

(c)          (i)
prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable
Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration Statements
in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause the related Prospectus to
be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented
or amended, to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any comments received from the
Commission with respect to a Registration Statement or any amendment thereto and provide as promptly as reasonably possible to
each seller of Registrable Securities true and complete copies of all correspondence from and to the Commission relating to a Registration
Statement (provided that, the Company shall excise any information contained therein which would constitute material non-public
information regarding the Company), and (iv) comply in all material respects with the applicable provisions of the Securities Act
and the Exchange Act, with respect to the disposition of all Registrable Securities covered by a Registration Statement during
the applicable period in accordance (subject to the terms of this Agreement) with the intended methods of disposition by each seller
of Registrable Securities thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented;

 

(d)          furnish
to each seller of Registrable Securities and to each underwriter such number of copies of the Registration Statement and the Prospectus
included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the intended
disposition of the Registrable Securities covered by such Registration Statement;

 

    	7

    	 

    

 

(e)          if
during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of shares of Common
Stock then registered in a Registration Statement, then the Company shall file an additional Registration Statement covering such
ineligible Registrable Securities, on a pro-rata basis, within 60 days of the date such securities become eligible for registration,
which date shall be determined by the Commission, and shall use its best efforts to cause such Registration Statement to be declared
effective by the Commission as soon as reasonably practicable;

  

(f)          use
its commercially reasonable efforts (i) to register or qualify the Registrable Securities covered by such Registration Statement
under the state securities or “blue sky” laws of such jurisdictions as the sellers of Registrable Securities or, in
the case of an underwritten public offering, the managing underwriter, reasonably shall request, (ii) to prepare and file in those
jurisdictions such amendments (including post-effective amendments) and supplements, and take such other actions, as may be necessary
to maintain such registration and qualification in effect at all times for the period of distribution contemplated thereby and
(iii) to take such further action as may be necessary or advisable to enable the disposition of the Registrable Securities in such
jurisdictions, provided, that the Company shall not for any such purpose be required to qualify generally to transact business
as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such
jurisdiction;

 

(g)          use
its commercially reasonable efforts to list the Registrable Securities covered by such Registration Statement with any securities
exchange on which the common stock of the Company is then listed;

 

(h)          immediately
notify each seller of Registrable Securities and each underwriter under such Registration Statement, at any time when a Prospectus
relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge
as a result of which the Prospectus contained in such Registration Statement, as then in effect, includes any untrue statement
of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing and promptly amend or supplement such Registration Statement to correct
any such untrue statement or omission;

 

(i)          if
the offering is an underwritten offering, enter into a written agreement with the managing underwriter selected in the manner herein
provided in such form and containing such provisions as are usual and customary in the securities business for such an arrangement
between such underwriter and companies of the Company’s size and investment stature, including, without limitation, customary
indemnification and contribution provisions;

 

(j)          if
the offering is an underwritten offering, at the request of any seller of Registrable Securities, furnish to such seller on the
date that Registrable Securities are delivered to the underwriters for sale pursuant to such registration: (i) a copy of an opinion,
dated such date, of counsel representing the Company for the purposes of such registration, addressed to the underwriters, stating
that such Registration Statement has become effective under the Securities Act and that (A) to the knowledge of such counsel, no
stop order suspending the effectiveness thereof has been issued and no proceedings for that purpose have been instituted or are
pending or contemplated under the Securities Act, (B) the Registration Statement, the related Prospectus and each amendment or
supplement thereof comply as to form in all material respects with the requirements of the Securities Act (except that such counsel
need not express any opinion as to financial statements or other financial or statistical information contained therein) and (C)
to such other effects as reasonably may be requested by counsel for the underwriters; and (ii) a copy of a letter dated such date
from the independent public accountants retained by the Company, addressed to the underwriters, stating that they are independent
registered public accountants within the meaning of the Securities Act and that, in the opinion of such accountants, the financial
statements of the Company included in the Registration Statement or the Prospectus, or any amendment or supplement thereof, comply
as to form in all material respects with the applicable accounting requirements of the Securities Act, and such letter shall additionally
cover such other financial matters (including information as to the period ending no more than five business days prior to the
date of such letter) with respect to such registration as such underwriters reasonably may request;

 

    	8

    	 

    

 

(k)          promptly
notify each seller of Registrable Securities of the issuance by the Commission of any stop order suspending the effectiveness of
the Registration Statement or the initiation of any proceedings for that purpose and make every reasonable effort to prevent the
issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible time;

 

(l)          take
all actions reasonably necessary to facilitate the timely preparation and delivery of certificates (not bearing any legend restricting
the sale or transfer of such securities) representing the Registrable Securities to be sold pursuant to the Registration Statement
and to enable such certificates to be in such denominations and registered in such names as each seller of Registrable Securities
or any underwriters may reasonably request; and

 

(m)          take
all other reasonable actions necessary to expedite and facilitate the registration of the Registrable Securities pursuant to the
Registration Statement.

 

6.            Obligations
of Investor. The Investor shall furnish to the Company such information regarding such Investor, the number of Registrable
Securities owned and proposed to be sold by it, the intended method of disposition of such securities and any other information
as shall be required to effect the registration of the Registrable Securities, and cooperate with the Company in preparing the
Registration Statement and in complying with the requirements of the Securities Act.

 

7.            Expenses.

 

(a)          All
expenses incurred by the Company in complying with Sections 3, 4 and 5 including, without limitation, all registration and
filing fees (including the fees of the Commission and any other regulatory body with which the Company is required to file), printing
expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including counsel
fees of the Company and the Placement Agent, as representative of the Purchasers, provided, however that any such counsel fees,
of the Placement Agent shall not exceed $50,000 in the aggregate and any related expenses shall not exceed $10,000 in the aggregate)
incurred in connection with complying with state securities or “blue sky” laws, and fees of transfer agents and registrars
are called “Registration Expenses.” All underwriting discounts and selling commissions applicable to the sale of Registrable
Securities are called “Selling Expenses.”

 

(b)          The
Company will pay all Registration Expenses in connection with any Registration Statement filed hereunder, and the Selling Expenses
in connection with each such Registration Statement shall be borne by the participating sellers in proportion to the number of
Registrable Securities sold by each or as they may otherwise agree.

 

    	9

    	 

    

 

8.         Indemnification
and Contribution.

 

(a)          In
the event of a registration of any of the Registrable Securities under the Securities Act pursuant to the terms of this Agreement,
the Company will indemnify and hold harmless and pay and reimburse, each seller of such Registrable Securities thereunder, each
underwriter of such Registrable Securities thereunder and each other person, if any, who controls such seller or underwriter within
the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller,
underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any Registration Statement under which such Registrable Securities were registered under the
Securities Act pursuant hereto or any preliminary prospectus or final prospectus contained therein, or any amendment or supplement
thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, or any violation or alleged violation of the Securities Act
or any state securities or “blue sky” laws and will reimburse each such seller, each such underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, that the Company will not be liable in any such case if and to the extent
that any such loss, claim, damage or liability arises out of or is based upon the Company’s reliance on an untrue statement
or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by any such seller,
any such underwriter or any such controlling person in writing specifically for use in such Registration Statement or prospectus.

 

(b)          In
the event of a registration of any of the Registrable Securities under the Securities Act pursuant hereto, each seller of such
Registrable Securities thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any,
who controls the Company within the meaning of the Securities Act, each officer of the Company who signs the Registration Statement,
each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the Securities
Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or such officer, director, underwriter
or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon reliance on any untrue statement or alleged untrue statement of
any material fact contained in the registration statement under which such Registrable Securities were registered under the Securities
Act pursuant hereto or any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof,
or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer, director, underwriter
and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action; provided that such seller will be liable hereunder in any such case if and only
to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as
such, furnished in writing to the Company by such seller specifically for use in such Registration Statement or prospectus; and
provided, further, that the liability of each seller hereunder shall be limited to the proceeds received by such seller from the
sale of Registrable Securities covered by such Registration Statement. Notwithstanding the foregoing, the indemnity provided in
this Section 8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or expense if
such settlement is effected without the consent of such indemnified party and provided further, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage or liability (or action in respect thereof) arises out of or is
based upon an untrue statement or alleged untrue statement or omission or alleged omission in such Registration Statement, which
untrue statement or alleged untrue statement or omission or alleged omission is completely corrected in an amendment or supplement
to the Registration Statement and the undersigned indemnitees thereafter fail to deliver or cause to be delivered such Registration
Statement as so amended or supplemented prior to or concurrently with the sale of the Registrable Securities to the person asserting
such loss, claim, damage or liability (or actions in respect thereof) or expense after the Company has furnished the undersigned
with the same.

 

    	10

    	 

    

 

(c)          Promptly
after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof,
but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified
party other than under this Section 8 and shall only relieve it from any liability which it may have to such indemnified
party under this Section 8 if and to the extent the indemnifying party is materially prejudiced by such omission. In case
any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof,
the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense
thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified
party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 8 for any legal expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided that if the defendants
in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably
concluded based upon written advice of its counsel that there may be reasonable defenses available to it that are different from
or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed
to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel
and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such
separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred.

 

(d)          In
order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i)
any holder of Registrable Securities exercising rights under this Agreement, or any controlling person of any such holder, makes
a claim for indemnification pursuant to this Section 8 but it is judicially determined (by the entry of a final judgment
or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal)
that such indemnification may not be enforced in such case notwithstanding the fact that this Section 8 provides for indemnification
in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling holder or any such
controlling person in circumstances for which indemnification is provided under this Section 8; then, and in each such case,
the Company and such holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion so that such holder is responsible for the portion represented by the percentage
that the public offering price of its Registrable Securities offered by the Registration statement bears to the public offering
price of all securities offered by such Registration statement, and the Company is responsible for the remaining portion; provided,
that, in any such case, (A) no such holder will be required to contribute any amount in excess of the public offering price of
all such Registrable Securities offered by it pursuant to such Registration statement and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 12(f) of the Securities Act) will be entitled to contribution from any person
or entity who was not guilty of such fraudulent misrepresentation.

 

9.           Changes
in Capital Stock. If, and as often as, there is any change in the capital stock of the Company by way of a forward or reverse
stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization,
or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted
hereby shall continue as so changed.

with the Commission, and (iii) such other reports and documents of the Company as such holder may reasonably request to avail itself
of any similar rule or regulation of the Commission allowing it to sell any such securities without registration.

 

12.          Termination.
All of the Company’s obligations to register Registrable Shares under Sections 3, 4, and 5 hereof shall terminate
upon the date on which the Investor holds no Registrable Securities or all of the Registrable Securities are eligible for resale

to the Company pursuant to a written opinion letter to such effect, addressed and reasonably acceptable to the Company’s
transfer agent and the Investor.

 

13.          Miscellaneous.

 

(a)          All

recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and the Investor

Signature Page to the Registration Rights Agreement

 

IN WITNESS WHEREOF, this Registration
Rights Agreement has been executed by Investor and by the Company on the respective date set forth below.

 

Investors:

 

The Investors set forth on Exhibit A
to the Purchase Agreement have executed a Subscription Agreement with the Company which provides, among other things, that by executing
the Subscription Agreement each Investor is deemed to have executed the REGISTRATION RIGHTS AGREEMENT in all respects and is bound
to purchase the Units set forth in such Subscription Agreement and Exhibit A to the Purchase Agreement.

 

THE COMPANY:

 

PROTEA BIOSCIENCES GROUP, INC.

 

	By:	 	 
	 	Name: Stephen Turner	 
	 	Title: Chief Executive Officer	 
	 	 
	Dated:  ______________________, 2014

Annex A

 

Plan of Distribution

 

Each selling stockholder
(the “Selling Stockholders”) of the securities and any of their pledgees, assignees and successors-in-interest
may, from time to time, sell any or all of their securities covered hereby on any stock exchange, market or trading facility on
which the securities of the Company are traded or in private transactions.  These sales may be at fixed or negotiated
prices.  A Selling Stockholder may use any one or more of the following methods when selling securities:

 

	 	 ̈	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

 

	 	 ̈	block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

 

	 	 ̈	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

 

	 	 ̈	an exchange distribution in accordance with the rules of the applicable exchange;

 

	 	 ̈	privately negotiated transactions;

 

	 	 ̈	settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

 

	 	 ̈	in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

 

	 	 ̈	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

 

	 	 ̈	a combination of any such methods of sale; or

 

	 	 ̈	any other method permitted pursuant to applicable law.

 

The Selling Stockholders may also sell securities
under Rule 144 under the Securities Act, if available, rather than under the prospectus contained in a Registration Statement.

 

Broker-dealers engaged
by the Selling Stockholders may arrange for other brokers-dealers to participate in sales.  Broker-dealers may receive
commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities,
from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an
agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal
transaction a markup or markdown in compliance with FINRA IM-2440.

 

In connection with the
sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions
they assume.  The Selling Stockholders may also sell securities short and deliver these securities to close out their
short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities.  The Selling
Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one
or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered
by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as
supplemented or amended to reflect such transaction).

The Selling Stockholders
and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within
the meaning of the Securities Act in connection with such sales.  In such event, any commissions received by such broker-dealers
or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act.  Each Selling Stockholder has informed the Company that it does not have any written or oral
agreement or understanding, directly or indirectly, with any person to distribute the securities. In no event shall any broker-dealer
receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

 

The Company is required
to pay certain fees and expenses incurred by the Company incident to the registration of the securities.  The Company
has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities
under the Securities Act.

 

Because Selling Stockholders
may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus
delivery requirements of the Securities Act including Rule 172 thereunder.  In addition, any securities covered by this
prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this
prospectus. The Selling Stockholders have advised us that there is no underwriter or coordinating broker acting in connection with
the proposed sale of the resale securities by the Selling Stockholders.

 

We agree to keep the prospectus
effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration
and without regard to any volume or manner-of-sale limitations and without current public information by reason of Rule 144 under
the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus
or Rule 144 under the Securities Act or any other rule of similar effect.  The resale securities will be sold only through
registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the
resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state
or an exemption from the registration or qualification requirement is available and is complied with.

 

Under applicable rules
and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously
engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation
M, prior to the commencement of the distribution.  In addition, the Selling Stockholders will be subject to applicable
provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of
purchases and sales of securities of the common stock by the Selling Stockholders or any other person.  We will make
copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus
to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).
