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:
1.
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;

2.
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
5.
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:
A.
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

B.
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.
