HSINCHU, Taiwan, April 12, 2013

HSINCHU, Taiwan, April 12, 2013 /PRNewswire-FirstCall/ -- ChipMOS TECHNOLOGIES
(Bermuda) LTD. ("ChipMOS" or the "Company") (Nasdaq: IMOS) today announced
that Gre Tai Securities Market ("GTSM") has approved the initial listing of
its subsidiary ChipMOS TECHNOLOGIES INC., a Taiwan corporation ("ChipMOS
Taiwan") on Taiwan's emerging stock board, with trading expected to begin on
April 19, 2013 under the proposed stock ticker 8150. ChipMOS will continue to
trade on NASDAQ under the ticker "IMOS", with no impact to or action required
by existing stockholders.

The Company and ChipMOS Taiwan, with the assistance of its underwriters,
Yuanta Securities Company, Limited and Capital Securities Corp., will continue
to work towards satisfying eligibility requirements for listing ChipMOS Taiwan
on the Taiwan Stock Exchange ("TSE") in the second quarter of 2014. Whether
requirements can be satisfied for the continued listing on Taiwan's emerging
stock board or the initial listing on the TSE depends in part on market
conditions and other factors not within the control of the Company or ChipMOS
Taiwan, including needed regulatory approvals. Even if ChipMOS Taiwan
receives these approvals, it does not guarantee it will be able to satisfy
other requirements. For these reasons, there can be no assurance that ChipMOS
Taiwan's shares will continue to trade on Taiwan's emerging stock board or
that ChipMOS Taiwan will be listed on the TSE.

The details concerning Company's Board of Directors approval of listing plans
for ChipMOS Taiwan were announced in a press release issued by the Company on
March 18, 2013.

S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "This is
another important step forward for us in our plan to both streamline our
corporate structure and to further enhance our global profile to the benefit
of ChipMOS and our investors."
