		Re:	Elafin License Agreement

 

Dear Ms. Bargmann,

 

This is to confirm certain agreements and understandings
reached between me and Proteo, Inc. in December 2012 based on the following background:

 

Pursuant to the provisions of the license agreement
between Proteo, Inc. (hereinafter “Licensee“) and myself (hereinafter “Licensor“, Licensee and Licensor
collectively the “Parties”) dated December 30th, 2000 as amended on December 23rd, 2008 and February
6th, 2012 (hereinafter the “License Agreement“), Licensee promised to pay certain amounts to Licensor. In
December 2007, December 2008 and February 2012, Licensee paid to Licensor 30,000 Euros per year and no other payments were made
under the License Agreement to Licensor as of February 10th, 2013. I herewith confirm that based on the foregoing we
have agreed on the following in December 2012:

 

		1.	The Parties herewith agree that Licensor defers to April 15, 2015 the installment payable by Licensee
in the amount of 330,000 Euros, which otherwise would be due on December 31, 2012 (30,000 €), on April 15, 2013 (60,000 €),
on December 31, 2013 (120,000 €) and on December 31, 2014 (120.000 €) (hereinafter the “Deferral”).

 

		2.	In the event that the Company's financial condition improves, the Parties would endeavor to enter
in good faith negotiations to accelerate the payments.

 

		3.	Neither the Deferral under Section 1 hereof nor the willingness to negotiate accelerated payments
as provided for in Section 2 hereof, would constitute a waiver of or estoppel to Licensor‘s rights to already existing or
future payment obligations under the License Agreement.

 

Please confirm by respective countersignature
that you are in agreement with this letter and with this confirmation of our agreement from December 2012.

 

Kind regards,

/s/ Oliver Wiedow

2010 PERFORMANCE INCENTIVE PLAN

RESTRICTED STOCK GRANT AGREEMENT

 

	The Plan and Other Agreements	
        The text of the Plan is incorporated in this Agreement by this reference.
        You and the Company agree to execute such further instruments and to take such further action as may reasonably be necessary to
        carry out the intent of this Agreement. Unless otherwise defined in this Agreement, certain capitalized terms used in this Agreement
        are defined in the Plan.

         

        This Agreement, the attached Exhibits and the Plan constitute the
        entire understanding between you and the Company regarding this Award of Restricted Stock. Any prior agreements, commitments or
        negotiations are superseded.

         

	Award of Restricted Stock	
        The Company awards you the number of shares of Restricted Stock
        shown on the cover sheet of this Agreement. The Award is subject to the terms and conditions of this Agreement and the Plan. This
        Award is not intended to constitute a nonqualified deferred compensation plan within the meaning of section 409A of the Code and
        will be interpreted accordingly.

         

	Vesting	
        This Award will vest according to the Vesting Schedule on the attached
        cover sheet.

         

	Escrow	
        The Company shall issue the Shares of Restricted Stock either (i)
        in certificate form or (ii) in book entry form, registered in the name of Participant, with legends, or notations, as applicable,
        referring to the terms, conditions and restrictions applicable to the Award.   Any certificate(s) for the Restricted
        Stock shall be deposited in escrow with the Secretary of the Company (or his/her designee) to be held in accordance with the provisions
        of this paragraph.  Each deposited certificate shall be accompanied by a duly executed Assignment Separate from Certificate
        in the form attached hereto as Exhibit A.  The deposited certificates shall remain in escrow until such time as the
        certificates are to be released or otherwise surrendered for cancellation as discussed below.

         

	 	
        All dividends whether in cash or in stock, if any, on the Restricted
        Stock shall also be held in escrow and subject to the same vesting terms and conditions as the Restricted Stock and such dividends
        shall only be paid to Participant upon vesting of the underlying Shares of Restricted Stock.

         

        The Restricted Stock held in escrow hereunder shall be subject to
        the following terms and conditions relating to their release from escrow or their surrender to the Company, provided, however,
        that the minimum number of Shares released to you in any individual release of Share certificates must be at least twenty-five
        (25) Shares (unless the release represents your final release of Share certificates from escrow):

         

    	-2-

    	 

    

 

	 	 •	 When your interest
        in the Restricted Stock vests, the Company shall, as applicable, either remove the notations on any such Shares of Restricted Stock
        issued in book entry form or deliver to Participant a stock certificate representing a number of Shares of Common Stock, equal
        to the number of Shares of Restricted Stock with respect to which have become vested.
         

 

	Non Transferability 	Restricted Stock shall not be sold, anticipated, assigned, attached, garnished, optioned, transferred or made subject to any creditor’s process, whether voluntarily, involuntarily or by operation of law.  If you attempt to do any of these things, this Award will immediately become invalid.  
	 	 
	Code Section 83(b) Election	
        You represent and warrant that
        you understand the Federal, state and local income tax consequences of the granting of this Restricted Stock. Under Section
        83 of the Code, the Fair Market Value of the Restricted Stock on the date any forfeiture restrictions applicable to such Restricted
        Stock lapse will be reportable as ordinary income at that time. For this purpose, “forfeiture restrictions” include
        surrender to the Company of unvested Restricted Stock as described above. You may voluntarily elect to be taxed at the time the
        Restricted Stock is acquired to the extent that the Fair Market Value of the Restricted Stock exceeds the amount of consideration
        paid by you (if any) for such Restricted Stock at that time rather than when such Restricted Stock ceases to be subject to such
        forfeiture restrictions, by filing an election under Section 83(b) of the Code with the Internal Revenue Service within thirty
        (30) days after the Date of Award. A form for making this election is attached as Exhibit B hereto. Failure to make this
        filing within the thirty (30) day period will result in the recognition of ordinary income by you as the forfeiture restrictions
        lapse. YOU ACKNOWLEDGE THAT IT IS YOUR SOLE RESPONSIBILITY, AND NOT THE COMPANY’S, TO FILE A TIMELY ELECTION UNDER CODE
        SECTION 83(b), EVEN IF YOU REQUEST THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON YOUR BEHALF. MOREOVER, YOU ARE RELYING
        SOLELY ON YOUR OWN ADVISORS WITH RESPECT TO THE DECISION AS TO WHETHER OR NOT TO FILE A CODE SECTION 83(b) ELECTION.

         

	Leaves of Absence	
        For purposes of this Agreement, while you are a common-law employee,
        your Service does not terminate when you go on a bona fide leave of absence that was approved by the Company (or its Parent,
        Subsidiary or Affiliate) in writing, if the terms of the leave provide for continued Service crediting, or when continued Service
        crediting is required by applicable law. Your Service terminates in any event when the approved leave ends, unless you immediately
        return to active work.

         

        The Company determines which leaves count for this purpose (along
        with determining the effect of a leave of absence on vesting of the Award), and when your Service terminates for all purposes under
        the Plan.

    	-3-

    	 

    

 

	Voting and Other Rights	Subject to the terms of this Agreement, you shall have all the rights and privileges of a stockholder of the Company while the Restricted Stock is held in escrow, including the right to vote and to receive dividends (if any).  
	 	 
	Restrictions on

Issuance	The Company will not issue any Restricted Stock or Shares if the issuance of such Restricted Stock or Shares at that time would violate any law or regulation.
	 	 
	Taxes and Withholding 	
        You will be solely responsible for payment of
        any and all applicable taxes, including without limitation any penalties or interest based upon such tax obligations, associated
        with this Award.

         

        The delivery to you of any Shares will not be
        permitted unless and until you have satisfied any withholding or other taxes that may be due. The delivery to you of any vested
        Shares will not be permitted unless and until you have satisfied any withholding or other taxes that may be due. Any such tax withholding
        obligations may be settled in the Company's discretion by the Company withholding and retaining a portion of the Shares from the
        Shares that would otherwise be deliverable to you under the vesting Restricted Stock as provided in the next two sentences. Such
        withheld Shares will be applied to pay the withholding obligation by using the aggregate fair market value of the withheld Shares
        as of the date of vesting. You will be delivered the net amount of vested Shares after the Share withholding has been effected
        and you will not receive the withheld Shares.

	 	 
	Restrictions on Resale	
        By signing this Agreement, you agree not to sell,
        transfer, dispose of, pledge, hypothecate, make any short sale of, or otherwise effect a similar transaction of any Shares acquired
        under this Award (each a “Sale Prohibition”) at a time when applicable laws, regulations or Company or underwriter
        trading policies prohibit the disposition of Shares.

         

        The Company shall have the right to designate one or more periods
        of time, each of which generally will not exceed one hundred eighty (180) days in length (provided however, that such period
        may be extended in connection with the Company’s release (or announcement of release) of earnings results or other material
        news or events), and to impose a Sale Prohibition, if the Company determines (in its sole discretion) that such limitation(s) is
        needed in connection with a public offering of Shares or to comply with an underwriter’s request or trading policy, or could
        in any way facilitate a lessening of any restriction on transfer pursuant to the Securities Act or any state securities laws with
        respect to any issuance of securities by the Company, facilitate the registration or qualification of any securities by the Company
        under the Securities Act or any state securities laws, or facilitate the perfection of any exemption from the registration or qualification
        requirements of the Securities Act or any applicable state securities laws for the issuance or transfer of any securities. The
        Company may issue stop/transfer instructions and/or appropriately legend any stock certificates issued pursuant to this Award in
        order to ensure compliance with the foregoing. Any such Sale Prohibition shall not alter the vesting schedule set forth in this
        Agreement.

    	-4-

    	 

    

 

	 	
        If the sale of Shares under the Plan is not registered under the
        Securities Act, but an exemption is available which requires an investment or other representation, you shall represent and agree
        at the time of grant of the Restricted Stock that the Shares being acquired under this Award are being acquired for investment,
        and not with a view to the sale or distribution thereof, and shall make such other representations as are deemed necessary or appropriate
        by the Company and its counsel.

         

        You may also be required, as a condition of this
        Award, to enter into any Company stockholder agreement or other agreements that are applicable to stockholders.

	 	 
	No Retention Rights	Your Award or this Agreement does not give you the right to be retained by the Company (or any Parent or any Subsidiaries or Affiliates) in any capacity.  The Company (or any Parent and any Subsidiaries or Affiliates) reserves the right to terminate your Service at any time and for any reason.
	 	 
	Extraordinary Compensation	This Award and the Shares subject to the Award are not intended to constitute or replace any pension rights or compensation and are not to be considered compensation of a continuing or recurring nature, or part of your normal or expected compensation, and in no way represent any portion of your salary, compensation or other remuneration for any purpose, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.
	 	 
	Adjustments	In the event of a stock split, a stock dividend or a similar change in the Company stock, the number of outstanding Shares of Restricted Stock covered by this Award may be adjusted (and rounded down to the nearest whole number) pursuant to the Plan.  Your Restricted Stock shall be subject to the terms of the agreement of merger, liquidation or reorganization in the event the Company is subject to such corporate activity.
	 	 
	Legends	
        All certificates or book entries representing the Common Stock issued
        under this Award may, where applicable, have endorsed thereon the following notations or legends and any other notation or legend
        the Company determines appropriate.

         

        “THE SHARES REPRESENTED BY THIS CERTIFICATE
        ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND OPTIONS TO PURCHASE SUCH SHARES SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY

SECTION 83(b) ELECTIONS

 

This memorandum briefly describes certain aspects
of Internal Revenue Code section 83 and section 83(b) elections as they exist under current law. A form of election is attached.
The effect of making the election is that it permits the employee or consultant to include in his or her gross income, in his or
her taxable year in which unvested shares are transferred, the excess, if any, of (i) the Fair Market Value of such shares
at the time of transfer (determined without regard to restrictions other than those which will never lapse), over (ii) the
amount (if any) paid for such shares.

 

By making the section 83(b) election, subsequent
appreciation in the value of the shares generally will be taxed as a capital gain, rather than as compensation. Also, appreciation
that occurs after the transfer but prior to vesting will not be taxed until the shares are sold. Finally, such subsequent appreciation
may be deferred if transfer occurs in a tax-free reorganization or may go untaxed altogether if a stepped-up basis results from
transfer by reason of death. However, if the shares are forfeited the employees or consultants who made the election can only deduct
a loss to the extent the amount received (if any) on forfeiture is less than the amount paid (if any) for such shares. Thus, such
employees or consultants are precluded from recovering the tax paid with respect to any reported compensation income. Moreover,
any loss recognized will generally be a capital loss which can only offset capital gains plus $3,000 of ordinary income ($1,500
in the case of married individuals filing a separate return).

 

In the absence of an election, the employee or
consultant who receives unvested shares does not recognize any income until such shares vest. In the taxable year in which any
shares vest such employee or consultant will recognize compensation income equal to the excess, if any, of (i) the Fair Market
Value of the vested shares on the vesting date, over (ii) the amount (if any) paid for such shares. If the shares are forfeited
the employee or consultant will recognize ordinary loss to the extent the amount received on forfeiture is less than the amount
paid for such shares.

 

The election must be made not later than 30 days
after the date of transfer of the shares to the employee or consultant. The election is to be filed with the Internal Revenue Service
Center with which the employee or consultant files his or her return. In general, the election is irrevocable.

 

Each filing should be made by certified mail with
the sender’s receipt postmarked at the time of mailing to establish proof of filing. Also, one copy of the election should
be filed with the company. Finally, one copy of the election must be submitted with the employee’s federal income tax returns
for the taxable year in which the shares are transferred. Although the election must be made within 30 days of the date of transfer
of the shares, the tax, if any, arising out of the election need not be paid until the employee or consultant files his or her
tax return for the tax year of transfer (subject to the withholding rules discussed below).

 

The company should be entitled to a tax deduction
for federal income tax purposes equal to the amount, if any, included in the gross income of the employees or consultants receiving
the shares. Any deduction is allowed for the taxable year of the company in which or with which ends the taxable year in which
the amount was included in the gross income of the employee or consultant.

 

While it may be desirable from a tax standpoint
for employees and consultants to make an 83(b) election at the time unvested shares are acquired, the matter should be reviewed
by each employee or consultant with his or her tax adviser.

 

The foregoing is intended only as a general summary
of the tax consequences of section 83(b) elections.
