In connection with each election of members of the Board of Directors of the Company where a Director Candidate is standing for election, Mr. Pentel agrees to vote all of his shares of common stock of the Company entitled to vote, whether now or hereafter owned or held of record by Mr. Pentel or as to which Mr. Pentel now or hereafter has voting power (his “Shares”), for such Director Candidate.

5.            Remedies. The Parties acknowledge that any violation of this Agreement will cause irreparable harm to the Parties hereto. As a consequence, the Parties agree that if any party fails to abide by the terms of this Agreement, the non-breaching Party will be entitled to specific performance, including the immediate issuance of a temporary restraining order or preliminary injunction enforcing this Agreement, and to judgment for damages cause by such breach, including attorneys’ fees, and to any other remedies provided by applicable law.

6.            Term.                The obligations of the Parties to this Agreement shall continue until the earlier of such time as the Investor no longer beneficially owns any of the Shares, Warrants or Warrant Shares issued in connection with the Securities Purchase Agreement, or the Agreement is voluntarily terminated by written notice of the Investor.

7.          Miscellaneous

(a)           Amendment. Except as expressly provided in this Agreement, neither this Agreement nor any term of this Agreement may be amended, waived, discharged, or terminated other than by a written instrument referencing this Agreement and signed by the Company and the Investor.

(b)          Notices. All notices and other communications required or permitted under this Agreement will be in writing and will be mailed by registered or certified mail, postage prepaid, sent by facsimile, sent by electronic mail, or otherwise delivered by hand or by messenger addressed:

(iv)         Each such notice or other communication will, for all purposes of this Agreement and the other Transaction Agreements, be treated as effective or having been given when delivered if delivered personally, or, if sent by mail, at the earlier of its receipt or 72 hours after such communication has been deposited in a regularly maintained receptacle for the deposit of the United States mail, addressed and mailed as specified above or, if sent by facsimile, upon confirmation of facsimile transfer or, if sent by electronic mail, when directed to the electronic mail address set forth above.

(c)           Governing Law. This Agreement will be governed in all respects by the internal laws of the State of Minnesota as applied to agreements entered into among Minnesota residents to be performed entirely within Minnesota, without regard to Minnesota conflicts-of-law principles.

(d)          Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable, or void, then this Agreement will continue in full force and effect without such illegal, unenforceable, or void provision, and the Parties agree to negotiate, in good faith, a legal and enforceable substitute provision which most nearly effects the Parties’ intent in entering into this Agreement as expressed in this Agreement.

A facsimile or other reproduction of this Agreement may be executed by one or more Parties, and an executed copy of this Agreement may be delivered by one or more Parties by facsimile or similar electronic transmission device pursuant to which the signature

(h)         Jurisdiction and Venue. With respect to any disputes arising out of or related to this Agreement, the Parties consent to the exclusive jurisdiction of, and venue in, the state courts in Hennepin County, Minnesota (or, in the event of exclusive federal jurisdiction, the federal courts of the District of Minnesota).

(i)          Further Assurances; Binding Agreement. Each Party agrees to execute and deliver, by the proper exercise of such Party’s corporate, limited liability company, partnership, or other powers, all such other and additional instruments and documents and do all such other acts and things as may be necessary to more fully perform this Agreement. This Agreement shall be binding upon the heirs, executors, administrators, successors and assigns of the parties hereto.

(j)          Construction. The Parties have participated jointly in negotiating and drafting this Agreement. If any ambiguity, question of intent, or question of interpretation arises with respect to this Agreement, then this Agreement will be construed as if drafted jointly by the Parties, and no presumption or burden of proof will arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.
