January 9, 2013

Enclosed with this letter are amended and restated versions (the “Amended Agreements”) of the following agreements which were originally entered into between Eos Petro, Inc. and Clouding IP, LLC on December 26, 2012 (the “”Original Agreements”): (1) an Oil & Gas Services Agreement; (2) a Warrant to Purchase Common Stock; (3) a Loan Agreement and Secured Promissory Note; and (4) a Leasehold Mortgage, Assignment, Security Agreement and Fixture Filing.

The Amended Agreements modify the following provisions of the Original Agreements:

(1) all of the agreements are now between Clouding IP, LLC and Cellteck, Inc., not Eos Petro, Inc. (Cellteck Inc. is Eos Petro, Inc.’s parent company). Since Cellteck is incorporated under Nevada law, the governing law in all of the agreements other than the Mortgage has also been changed to Nevada.

(2) the shares issuable to Clouding IP, LLC under the Loan Agreement and Secured Promissory Note have been changed from shares of common stock of Eos Petro, Inc. to shares of Series B Preferred Stock of Cellteck, Inc.

(3) The obligation to record the loan within seven business days has been removed from the Loan Agreement and Secured Promissory Note.

(4) “Failure to Deliver Common Stock” has been removed from the events of default in the Loan Agreement and Secured Promissory note.

(5) the shares issuable to Clouding IP, LLC upon exercise of the Warrant to Purchase Common Stock have been changed to shares of common stock of Cellteck, Inc. Furthermore, to protect such shares from dilution upon the occurrence of an upcoming reverse stock split:

(a) the warrants will not be exercisable until effectuation of the reverse stock split; and

(b) anti-dilution provisions specifically relating to the upcoming reverse stock split have been inserted.

(6) the cashless exercise option has been removed from the Warrant to Purchase Common Stock.

(7) the warrants issuable to Clouding IP, LLC under the Oil & Gas Services Agreement are issuable in consideration of Clouding IP, LLC’s services without the need for Clouding to make an additional $5,000 payment.

The Amended Agreements amend and restate the Original Agreements in their entirety. By signing this letter and the attached Amended Agreements, the undersigned parties hereby acknowledge that: (i) they have read, understand and consent to the modifications made to the Original Agreements in the Amended Agreements; and (ii) the Original Agreements are voided in their entirety by the attached Amended Agreements and have no further effect.

1.          SERVICES.

On behalf of each Service Company, Clouding hereby agrees to provide such Services, subject to the terms and conditions set forth in this Agreement. The Service Companies shall provide the Services under this Agreement in a professional manner observing the best-practices standards of care prevailing in the oil and gas industry. The Parties recognize that the Service Companies render services similar to the Services to other third parties, and, subject to the Service Companies rendering the Services in a manner required under this Agreement, this Agreement shall not restrict the Service Companies from rendering such other services. In addition to the Services, the Service Companies covenant and agree to make known to Cellteck , on a most favored nations basis, any business opportunities of a nature sought by Cellteck and that are known to any of the Service Companies.

2. RATES; SELECTION. The rates for the Services shall be on a most favored nations basis and Cellteck agrees to utilize the Service Companies for Services sought by Cellteck when, in Cellteck’s judgment and based on such criteria as Cellteck in exercise of its business judgment deems appropriate, Cellteck determines that the Service Companies are highly qualified to render the Services when, where and as needed and are also price- and time-competitive in rendering the Services.

3. TERM. The Agreement shall commence on the Commencement Date and shall continue until December 31, 2013, provided that this Agreement shall govern any Services contracted for on or prior to December 31, 2013 until the final performance of such contracted Services.

7. INDEPENDENT CONTRACTORS. The Service Companies shall perform their Services hereunder as independent contractors and not as an employee of Cellteck or an affiliate thereof. It is expressly understood and agreed to by the parties hereto that the Service Companies shall have no authority to act for, represent or bind Cellteck or any affiliate thereof in any manner, except as may be agreed to expressly by Cellteck in writing from time to time.

Accordingly, the Parties acknowledge that they have considered retaining or have retained legal counsel to review this Agreement and that each Party has been provided with adequate time to obtain such review.

(c)          Arbitration. The Parties agree that in the event of any and all disagreements and controversies arising from this Agreement such disagreements and controversies shall be subject to binding arbitration before Manizales Alternative Resolution Centers (“MARC”) as arbitrated in accordance with the then current Commercial Arbitration Rules of MARC to be held in Los Angeles, California before one neutral arbitrator. Either Party may apply to the arbitrator seeking injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Without waiving any remedy under this Agreement, either Party may also seek from any court having jurisdiction any interim or provisional relief that is necessary to protect the rights or property of that Party, pending the establishment of the arbitral tribunal (or pending the arbitral tribunal’s determination of the merits of the controversy). In the event of any such disagreement or controversy, neither Party shall directly or indirectly reveal, report, publish or disclose any information relating to such disagreement or controversy to any person, firm or corporation not expressly authorized by the other Party to receive such information or use such information or assist any other person in doing so, except to comply with actual legal obligations of such Party or unless such disclosure is directly related to an arbitration proceeding as provided herein, including, but not limited to, the prosecution or defense of any claim in such arbitration.

This Agreement contains the entire agreement and understanding between the parties and merges and supersedes any prior understandings or agreements, whether written or oral. The provisions of this Agreement shall be amended or waived only with the written consent of both parties hereto.

(e)          Successors and Assigns. This Agreement shall be binding upon, inure to the benefit of, and shall be enforceable by Clouding and Cellteck and their respective successors and permitted assigns.

(f)          Nonwaiver of Rights.
