Dear Sirs

Sale and purchase of the entire issued share capital of Starhome BV

We refer to the share purchase agreement in relation to the sale and purchase of the entire issued share capital of Starhome B.V. (the "Company") to be entered into on or around the date of the letter between (1) Fortissimo Capital Fund II (Israel), L.P., Fortissimo Capital Fund III (Israel), L.P. and Fortissimo Capital Fund III (Cayman), L.P.,, (2) the Company, (3) the shareholders of the Company and (4) the Sellers Representatives (the "Share Purchase Agreement") and in particular to the consideration payable under the Share Purchase Agreement.

Words and expressions used but not defined in this letter shall have the meanings given to them in the Share Purchase Agreement.

In consideration of Berkeley and Gemini entering into the Share Purchase Agreement, we hereby agree and irrevocably undertake to each of Berkeley and Gemini that:

notwithstanding anything to the contrary in the Share Purchase Agreement, the Articles of Association of the Company or any other document, if (a) Berkeley's portion of the Aggregate Purchase Price is less than US$29,500,000 and (b) Gemini's aggregate portion of the Aggregate Purchase Price is less than US$7,375,000 (in each case calculated in respect of the purchase price payable for the Shares and the return to Shareholders of excess cash in the Company but before any deduction to satisfy the Indemnity Escrow Amount and/or any other claims or liabilities under the Share Purchase Agreement) (collectively, the "Minimum Proceeds"), then we shall compensate each of Berkeley and Gemini for such difference (as to each of Berkeley and Gemini, the "Shortfall Amount") pro-rata to the Aggregate Purchase Price amounts set out above and up to a maximum aggregate amount of US$4,500,000 (the “Cap”), payable in accordance with this letter;

we shall, within twenty (20) Business Days after receipt by us of our Seller's Closing Payment pursuant to the Share Purchase Agreement, transfer to Berkeley and Gemini respectively (by electronic transfer for same day value to accounts nominated by each of them in writing) such amount from our Seller's Closing Payment as is necessary to ensure that, after taking into account any sum received directly by Berkeley and Gemini under the Share Purchase Agreement, Berkeley and Gemini each receive their respective Shortfall Amounts (subject to the Cap), less an amount equal to the proportionate increase in Berkeley and Gemini's Indemnity Escrow Amount (the "Proportionate Escrow Amounts") as set forth in paragraph A below;


3.	we shall, within twenty (20) Business Days after receipt of by us of the same, transfer to Berkeley and Gemini respectively (by electronic transfer for same day value to accounts nominated by each of them in writing) any amounts received by us in relation to a release from the Indemnity Escrow Amount of the whole or any part of their respective Proportionate Escrow Amounts;


4.	notwithstanding anything to the contrary in the Share Purchase Agreement, the Articles of Association of the Company or any other document, in the event that the total aggregate proceeds payable under Share Purchase Agreement to Shareholders (including in respect of the purchase price payable for the Shares and the return to shareholders of excess

cash in the Company) exceed US$79,722,000, we (in respect of our Class A Shares only) shall participate with Berkeley and Gemini in such excess (collectively, the "Excess Proceeds") on the basis of the formulas set out below:

Berkeley:

A = Y/(X+Y+Z)

Where:

A = the Excess Proceeds to be received by Berkeley, in US$;

X = US$7,375,000;

Y = US$29,500,000; and

Z = US$36,128,000;

Gemini:

B = X/(X+Y+Z)

Where:

B = the Excess Proceeds to be received by Gemini, in US$; and

X, Y and Z have the same value as set out above;

Comverse:

C = Z/(X+Y+Z)

Where:

C = the Excess Proceeds to be received by us, in US$; and

X, Y and Z have the same value as set out above; and

to the extent we receive payments under the Share Purchase Agreement that are required to be shared with Berkeley and Gemini on the basis set out in paragraph 4 above, we shall within twenty (20) Business Days after receipt by us of our Seller's Closing Payment pursuant to the Share Purchase Agreement transfer to Berkeley and Gemini respectively (by electronic transfer for same day value to accounts nominated by each of them in writing) such amount from our Seller's Closing Payment as is necessary to ensure that, after taking into account any sum received directly by Berkeley and Gemini under the Share Purchase Agreement, Berkeley and Gemini each receive their respective Excess Proceeds in full.

In consideration for our agreement to pay to Berkeley and Gemini their respective Shortfall Amounts, Berkeley and Gemini each agree that:

firstly, their respective portions of the Escrow Indemnity Amount shall be increased, and our portion of the Escrow Indemnity Amount shall be decreased, in each case by an amount equal to that percentage of the Shortfall Amount as is equal to the percentage of the Net Purchase Price represented by the Indemnity Escrow Amount, and, secondly, the Pro Rata Share of each of them shall be increased, and our Pro Rata Share shall be decreased, in each case to the extent necessary to reflect their receipt of the Minimum Proceeds and our payment of the Shortfall Amount (subject to the Cap), and the corresponding reduction of our Seller's Closing Payment; and

to the extent Berkeley and Gemini receive payments under the Share Purchase Agreement that are required to be shared with us on the basis set out in paragraph 4 above, (a) such amount shall first be offset against amounts owing to Berkeley and Gemini pursuant to paragraph 2 hereof and (b) to the extent there any amounts remaining after giving effect to such offset, Berkeley and Gemini shall within twenty (20) Business Days after receipt by Berkeley and Gemini of their respective Seller's Closing Payments pursuant to the Share Purchase Agreement transfer to us (by electronic transfer for same day value to accounts nominated by us in writing) such amount from their respective Seller's Closing Payments as is necessary to ensure that, after taking into account any sum received directly by us under the Share Purchase Agreement,

we receive our Excess Proceeds in full.
