less than all, of such Holder’s Series A Shares shall be exchanged as described in Section 1.2

other actions reasonably required to effectuate the transfer of all such Holder’s Series A Shares

to WaferGen US. WaferGen US may nominate its nominee(s) to accept the transfer of the Series

until the fifth anniversary of the date of this Agreement, but may in its sole discretion comply

with provisions of this paragraph after such date.

of the Holder’s Series A Shares subject to such Holder’s Put Notice shall be converted into the

right to receive that number of Exchange Securities equal to the U.S. dollar equivalent of the

original purchase or subscription price per share paid for each such Holder’s Series A Share

(with such conversion to U.S. dollars being calculated as of the date of purchase) pursuant to the

Purchase Agreement, divided by the Exchange Price1 (in each case as adjusted for stock splits,

recapitalization, combinations and similar transactions). All Exchange Securities shall be

aggregated and issued to such Holder, except that no fractional shares of Exchange Securities

shall be issued upon the occurrence of an Exchange. If, after the aforementioned aggregation,

the conversion would result in the issuance of any fractional share, WaferGen US shall, in lieu of

issuing any fractional share, pay cash equal to the product of such fraction multiplied by the per

share fair market value of the Exchange Securities (as determined in good faith by the Board of

Directors of WaferGen US). Subject to the delivery by the Holder of its share certificates and

other documents to WaferGen US as required hereby, upon the occurrence of the Exchange,

shares (except the right to receive the Exchange Securities, and any cash payment for fractional

shares, without interest upon surrender of their certificate or certificates), and such shares shall

be owned legally and beneficially by WaferGen US for all purposes and will be transferred to

WaferGen US on the books and records of the Company.

     1.4      Rights After Conversion. If at any time any or all of Holder’s Series A Shares are
