Article 2

Right to Exchange

Section 2.01. Grant of Exchange Right. On the terms and subject to the conditions of this Agreement, at any time and from time to time during the Exercise Period, each Member shall have the right (the “Exchange Right”), but not the obligation, to exchange all or any portion of the OML Units held by such Member for shares of Odyssey Common Stock.

Section 2.02. Exchange Procedures.

(a) Exercise of Exchange Right. If any Member desires to exercise the Exchange Right and acquire shares of Odyssey Common Stock to this Section 2, such Member shall deliver to Odyssey:

(i) a written, unconditional, and irrevocable notice in the form attached as Exhibit A (an “Exchange Exercise Notice”);

(ii) an investor questionnaire in the form attached as Exhibit B (an “Investor Questionnaire”); and

(iii) a written, unconditional, and irrevocable assignment of units in the form attached as Exhibit C (an “Assignment”).

(b) Suitability Determination. Upon delivery of the Exchange Documents to Odyssey, Odyssey shall review the Exchange Documents to evaluate whether the Member exercising the Exchange Right is an “accredited investor” as defined in Rule 501(a) under the Securities Act (a “Suitable Investor”). As soon as practicable (and in any event within five Business Days) after delivery of the Exchange Documents to Odyssey, Odyssey shall deliver to such Member either (i) a written notice to the effect that Odyssey has determined in good faith that such Member is not a Suitable Investor (a “Rejection Notice”) or (ii) a written notice to the effect that Odyssey has determined in good faith that such Member is a Suitable Investor (an “Acceptance Notice”). If Odyssey delivers a Rejection Notice to such Member, Odyssey shall include with such Rejection Notice the Exchange Documents delivered to Odyssey with the Exchange Exercise Notice. If Odyssey delivers an Acceptance Notice to such Member, the exchange of such Member’s OML Units for shares of Odyssey Common Stock shall be completed in accordance with Section 2.02(c).

(c) Completion of Exchange. If Odyssey delivers an Acceptance Notice to a Member in accordance with Section 2.02(b), as soon as practicable thereafter (and in no event more than five (5) Trading Days thereafter) Odyssey shall deliver, or cause to be delivered to such Member, a number of shares of Odyssey Common Stock equal to the product of (i) the number of OML Units such Member desires to exchange, as set forth in the Exchange Exercise Notice, multiplied by (ii) a fraction, the numerator of which is the OML

2

Per Unit Value and the denominator of which is the Odyssey Per Share Value, in each case determined as of the date of the Exchange Exercise Notice. Upon any exchange of OML Units for shares of Odyssey Common Stock pursuant to this Article 2, in lieu of any fractional shares to which such Member would otherwise be entitled, the number of shares of Odyssey Common Stock issuable to such Member shall be rounded up to the next whole share.

Section 2.03. Certain Adjustments.

(a) Stock Split, Stock Dividend, Etc. If Odyssey at any time on or after the date hereof subdivides (by any stock split, stock dividend, recapitalization or otherwise) the Odyssey Common Stock into a greater number of shares, the number of shares of Odyssey Common Stock issuable upon exercise of the Exchange Right will be proportionately increased. If Odyssey at any time on or after the date of issuance combines (by combination, reverse stock split or otherwise) the Odyssey Common Stock into a smaller number of shares, the number of shares of Odyssey Common Stock issuable upon exercise of the Exchange Right will be proportionately decreased. Any adjustment pursuant to this Section 2.04(a) shall become effective immediately after the effective date of such subdivision or combination.

(b) Reorganization, Merger, Etc. If there is a reorganization, or a merger or consolidation of Odyssey with or into any other entity which results in a conversion, exchange, or cancellation of the Odyssey Common Stock, upon any subsequent exercise of the Exchange Right, each holders of OML Units will be entitled to receive the kind and amount of securities, cash, and other property or assets which such holder would have received if such holder had exercised the Exchange Right immediately prior to the first of these events and had retained all the securities, cash, and other property or assets received as a result of those events.

Section 2.04. Limitation on Number of Shares Issuable. Notwithstanding anything herein to the contrary, the aggregate maximum number of shares of Odyssey Common Stock that may be issued in connection with one of more exercises of the Exchange Right pursuant to this Agreement shall not (a) exceed 19.9% of the number of outstanding shares of Odyssey Common Stock immediately prior to the date of this Agreement, (b) exceed 19.9% of the combined voting power of the outstanding voting securities of Odyssey immediately prior to the date of this Agreement, or (c) otherwise exceed such number of shares of Odyssey Common Stock that would violate applicable listing rules of the Principal Market.

Section 2.05. Further Assurances. Any Member that exercises the Exchange Right shall from time to time a execute and deliver to Odyssey such additional documents, instruments, agreements, consents, and shall provide such additional information and take such other actions as Odyssey may reasonably request to carry out the terms of this Agreement.
