We hereby apply for the allotment of 2,500,000 Ordinary Shares of 1p each in the capital of Rubicon (the “Initial Shares”), for a subscription price of £0.02 (two pence) per share.

2.2.  
Subject to the consent of both parties and on Us providing notice in writing to You, We agree to subscribe for a further number of Ordinary shares in the capital of Rubicon as we shall determine, subject to a maximum subscription of 2,500,000 New Ordinary Shares (such further shares being the “Second Tranche Shares”).

2.3.  
The subscription price for the Second Tranche Shares shall be £0.02 (two pence) per share.  Our right to subscribe for the Second Tranche Shares shall expire on the date that is 90 days from the date of this Agreement.

2.4.  
You undertake to take all corporate action, including obtaining all necessary board and shareholder approvals, and complying with all applicable legal and regulatory requirements in order to effect the allotment of the Initial Shares and (if applicable) the Second Tranche Shares, following receipt of payment for such share subscription/s by Us.  Each allotment shall take place no later than seven business days after receipt of written notice and appropriate payment from Us in respect of the subscription in question, or, if following such notice and payment, approval for such allotment is required, no later than seven business days after such allotment has been approved at a Rubicon EGM.

We shall be entitled, upon providing seven days written notice to You, to subscribe for 1 New Ordinary Share of 1p each in the capital of Rubicon (each being a “Warrant Share”) for every £1.00 of gross revenue received by Rubicon (less any applicable VAT) pursuant to the SAA.

3.3.  
Each Warrant Share subscribed for pursuant to paragraph 3.2 above shall be for a price of £0.05 (five pence) per share, and We shall subscribe and be issued with Warrant Shares in tranches of 100,000 shares.

You undertake to take all corporate action, including obtaining all necessary board and shareholder approvals, and complying with all applicable legal and regulatory requirements in order to effect the allotment of each tranche of Warrant Shares following receipt of payment for such subscription/s for Warrant Shares by Us.  Each allotment of Warrant Shares shall take place no later than seven business days after receipt of written notice and appropriate payment from Us in respect of the subscription in question, or, if following such notice and payment, approval for such allotment is required, no later than seven business days after such allotment has been approved at a Rubicon EGM.

4.  
Issue of shares in ISA

4.1.  
You and We agree to meet and negotiate in good faith in order to agree upon the terms of a warrant whereby Rubicon will have the right to subscribe for Ordinary Shares in ISA.  We and You intend that any such warrant, when agreed, will be structured as a transaction exempt from registration under the Securities Act of 1933 pursuant to the provisions of “Regulation S” as promulgated by the Securities and Exchange Commission.

5.

Neither You nor We may assign any of our rights under this Agreement without the prior written consent of the other.
