Gentlemen:

     Reference is made to the Asset Purchase Agreement, dated as of the date hereof (as it may be amended from time to time, the “Asset Purchase Agreement”), by and among CRX Acquisition Ltd., a Bermuda exempted company (“Purchaser”), FB Transportation Capital LLC, a Delaware limited liability company (“Sponsor”), and The Cronos Group, a limited liability company (société anonymé holding) organized and existing under the laws of the Grand Duchy of Luxembourg (the “Company”), pursuant to which Purchaser, or a permitted assignee of Purchaser, will acquire the assets and assume the liabilities of the Company subject to and in accordance with its terms. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Asset Purchase Agreement.

     The undersigned is entering into this commitment letter agreement (“Equity Commitment Letter”) at or about the same time that certain other holders of Common Shares of the Company are entering into Equity Commitment Letters with Purchaser having terms substantially similar hereto. The undersigned, such other Persons who are parties to such other Equity Commitment Letters and any other Persons who become parties to Equity Commitment Letters with Purchaser after the date hereof, are collectively referred to herein as the “Investors”. This letter is being delivered to Sponsor and Purchaser in connection with the execution and delivery of the Asset Purchase Agreement by Purchaser, Sponsor and the Company.

     This letter confirms the commitment of the undersigned, subject to the conditions set forth herein, to contribute and deliver to Purchaser at or immediately prior to the Closing cash in the amount set forth on Schedule A attached hereto (and which is made a part hereof) (the “Committed Cash”) in exchange for that number of common shares of Purchaser, US$0.01 par value per common share (such common shares of Purchaser being referred to herein as the “Subject Equity Securities”) set forth on Schedule A. The amounts and consideration referred to above and in Schedule A are subject to upwards adjustment under certain circumstances as set forth below; provided however, that the undersigned shall not, under any circumstances, be obligated to contribute to Purchaser an amount of cash in excess of the “Maximum” amount of Committed Cash set forth on Schedule A. The undersigned’s obligation hereunder to contribute and deliver the Committed Cash to Purchaser is herein referred to as the “Commitment”), and such obligation is subject in all respects to (a) the terms of this letter, (b) the satisfaction of the

1

conditions precedent to Purchaser’s and Sponsor’s obligations to effect the Closing, (c) the performance in full by the other Investors of their obligations under their respective Equity Commitment Letters and (d) the issuance to the undersigned of the Subject Equity Securities (all of which will be deemed to occur immediately prior to the Closing). The other terms and conditions regarding the undersigned’s proposed investment in Purchaser are summarized in Schedule B, which is attached hereto and made a part hereof.

     The undersigned’s obligation hereunder to contribute and deliver to Purchaser the Committed Cash will terminate automatically and immediately upon the earlier to occur of the following: (a) the termination of the Asset Purchase Agreement and (b) the Closing.

     The undersigned and Purchaser also each agree to enter into, effective upon the Closing, definitive agreements reflecting the terms and conditions set forth in this letter and those referred to or summarized in Schedule B hereof, with such agreements, (a) in each case, containing such other terms as are (i) not materially inconsistent with the terms and conditions hereof and those summarized in Schedule B and (ii) not materially adverse to the undersigned, Sponsor or Purchaser, and (b) including a definitive employment agreement containing terms and conditions substantially the same as those contained in Exhibit I which is attached hereto and made a part hereof.

     Effective immediately prior to the Closing, the employment agreement(s) of the undersigned with the Company shall terminate, and undersigned shall have no rights or entitlements thereunder, provided that such termination is subject to the satisfaction of all of the following conditions:

(a) The transactions contemplated by the Asset Purchase Agreement are consummated in accordance with the terms thereof, including the undersigned’s exercise of any Stock Options, redemption of any SARs, settlement of any Stock Units, and claiming of vested ownership of any Restricted Shares, as the case may be, on an accelerated vesting basis as contemplated by Section 2.3 of the Asset Purchase Agreement; and

(b) Simultaneously with the Closing, the undersigned and Purchaser shall have entered into the agreements referred to in the first immediately preceding full paragraph above.

Should any of such conditions not be satisfied, the employment agreement(s) of the undersigned referred to above shall remain in full force and effect in accordance with their respective terms.

     Nothing hereunder shall limit or restrict the undersigned from exercising any duties to the Company, its Board of Directors or its Shareholders to the extent the exercise of such duties is otherwise permitted under Section 8.1 of the Asset Purchase Agreement.

     The undersigned’s rights and obligations under this Equity Commitment Letter may not be assigned without the prior written consent of Purchaser, and any attempted assignment shall be null and void and of no force or effect. Except to the extent otherwise agreed to by Purchaser, any such permitted assignment shall not relieve the undersigned of its obligations under this

2

letter. This letter may not be amended, and no provision hereof waived or modified, except by an instrument in writing signed by Purchaser and the undersigned and approved in writing by Sponsor. Notwithstanding the foregoing, the undersigned and Purchaser acknowledge and agree that the structure and terms of the proposed investment contemplated hereunder may be subject to change upon and subject to the mutual consent of the parties hereto.

     Purchaser may assign its rights and obligations hereunder to an entity affiliated with Purchaser, provided that (i) such assignment shall not relieve Purchaser of its obligations hereunder and (ii) such assignment does not adversely affect in any material respect the undersigned’s rights or benefits hereunder.

     This Equity Commitment Letter shall be binding on and inure to the benefit of the undersigned and Purchaser and their respective heirs, guardians, representatives, trustees, executors, successors and permitted assigns, and nothing set forth in this letter shall be construed to confer upon or give to any Person other than the undersigned, Sponsor and Purchaser and their respective successors and permitted assigns, any benefits, rights or remedies under or by reason of, or any rights to enforce the Commitment or any other provisions of this letter.

     The undersigned represents and warrants to Purchaser that: (i) the undersigned has the requisite capacity and authority to execute and deliver this letter and to fulfill and perform the undersigned’s obligations hereunder; (ii) this letter has been duly and validly executed and delivered by the undersigned and constitutes a legal, valid and binding agreement of the undersigned enforceable by Purchaser against the undersigned in accordance with its terms; (iii) the undersigned has full and unrestricted power and authority to enter into and perform his or its obligations under this letter agreement without the consent or approval of, or any other action on the part of, any other Person; (iv) other than the filing by the undersigned of any reports with the SEC, neither the execution and delivery of this letter by the undersigned, nor the consummation by the undersigned of the transactions contemplated hereby, nor the compliance by the undersigned with any of the provisions hereof (1) requires any consent or other permit of, or filing with or notification to, any Governmental Entity or any other Person by the undersigned, (2) results in a violation or breach of, or constitutes (with or without notice or lapse of time or both) a default (or gives rise to any third party right of termination, cancellation, material modification or acceleration) under any of the terms, conditions or provisions of any agreement, document or instrument to which the undersigned is a party or by which the undersigned may be bound or affected, (3) violates any law or order or judgment of any governmental authority applicable to the undersigned, or (4) results in a lien or encumbrance upon any of the property of the undersigned; and (v) the undersigned has not entered into any actual or planned disposition of Common Shares, commitment or other agreement or arrangement that is inconsistent with the terms of this letter. The undersigned covenants and agrees that from and after the date hereof and for so long as this letter remains in effect, the undersigned shall not take or omit to take any action that would or would cause or result in any of the foregoing representations and warranties to become untrue.

     This letter may be executed in counterparts. This letter and any related dispute shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York applicable to contracts executed in and to be performed in that State.

It is presently anticipated that a third party investor or investors that are accredited investors (“Third Party Investors”) will join in such acquisition of Common Shares with FBT and the Management Parties. FBT, the Third Party Investors and the Management Parties are sometimes referred to herein as the “Investor Parties.” The Third Party Investors that will make equity investments in Purchaser in accordance with this Summary of Terms will be subject to the prior approval by FBT, which approval will not be unreasonably withheld.

Liquidation Event:		Purchaser will use its commercially reasonable efforts to explore a Liquidation Event by the end of the fifth year following the date of the Shareholders Agreement. It is anticipated that such Liquidation Event will result in aggregate net proceeds of at least $30.0 million, and a minimum consideration to the Investor Parties attributed to the Common Shares of $2.50 per share (such price being subject to usual and customary adjustments for stock splits, reverse splits, stock dividends and similar recapitalization events).
		“Liquidation Event” means any transaction or series of related transactions constituting: (i) a voluntary or involuntary liquidation, reorganization, dissolution or winding up of Purchaser, (ii) a direct

5

		or indirect, transfer, in one or a series of transactions, of all or substantially all of the assets of Purchaser, (iii) a sale, amalgamation, merger, reclassification, recapitalization, restructuring, consolidation or business combination or any other similar transaction of or involving Purchaser, unless the holders of record of Purchaser’s voting stock as constituted immediately prior to the consummation of any such transaction will, immediately after any such transaction hold greater than 50% of the voting stock of the acquiring entity or surviving entity, or either of such entities’ parent, in approximately the same relative percentages after any such transaction as before any such transaction, or (iv) the consummation of any transaction by which any person or group (as referred to in Section 13(d)(3) of the Exchange Act), other than FBT, the Third Party Investors or any of their respective permitted transferees, is or becomes the “beneficial owner” (as such term is defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% or more of the voting stock of Purchaser.
		Until the fifth anniversary of the date of the Shareholders Agreement, the approval of a Liquidation Event described in clauses (ii) or (iii) above in the immediately preceding paragraph shall also require the affirmative vote of Shareholders holding at least 65% of the outstanding shares of Common Shares. On and after the fifth anniversary of the date of the Shareholders Agreement, the approval of a Liquidation Event described in such clauses (ii) or (iii) shall require only the affirmative vote of Shareholders holding not less than the minimum statutorily required percentage of shares outstanding in order for such proposal to be approved. The Purchaser’s charter shall contain these provisions.
Purchase or Repurchase of Investor Parties’ Shares:		For the first five (5) years following the execution and delivery of the Shareholders Agreement, the Purchaser and the Shareholders will be subject to usual and customary share purchase and repurchase arrangement provisions to be determined by mutual agreement by and among the Purchaser and the Investor Parties (including the Management Parties), including rights of first refusal and rights to purchase and repurchase Common Shares upon the occurrence of certain events affecting an Investor Party, such as death, disability, divorce, foreclosure, retirement, insolvency, voluntary or involuntary transfer or sale and termination of employment of an Investor Party. Following such five (5) year period, it is currently intended that the Shareholders shall not be subject to such purchase or repurchase arrangements by or on behalf of the Purchaser and such other Investor Parties.
Termination:		All rights under the Shareholders Agreement shall terminate upon a Liquidation Event.

6

In addition, the parties shall have piggyback registration rights and the agreement shall contain such other usual and customary provisions as the parties may agree.
