Pericom Semiconductor : Independent Proxy Advisory Firm ISS Recommends in Favor of Pericom’s Merger with Diodes

Milpitas, CA - November 9, 2015 - Pericom Semiconductor Corporation ('Pericom' or the 'Company')
(NASDAQ: PSEM) announced today that Institutional Shareholder Services ('ISS') has issued detailed
reports recommending that Pericom shareholders vote in favor of the previously announced merger
agreement between Pericom and Diodes Incorporated ('Diodes') (NASDAQ: DIOD), dated September 2,
2015 (as amended, the 'Diodes Merger Agreement'), at the upcoming Special Meeting of Pericom
Shareholders. The Company also announced that its Board of Directors has sent a letter to Pericom
shareholders regarding the ISS reports and reiterating the Board's unanimous support for the
transactions contemplated by the Diodes Merger Agreement.

The text of the letter is as follows:

November 9, 2015

Dear Shareholders,

We are pleased that leading independent proxy advisory firm Institutional Shareholder Services ('ISS')
has issued detailed reports recommending that you vote the WHITE proxy card in favor of the
previously announced merger agreement between Pericom and Diodes Incorporated ('Diodes')
(NASDAQ: DIOD), dated September 2, 2015 (as amended, the 'Diodes Agreement'), at Pericom's
upcoming Special Meeting of Shareholders (the 'Meeting') to be held on November 20, 2015.
As your Board shared with you recently, the Diodes Agreement provides Pericom shareholders with
substantial and immediate cash value - $17.75 in cash per share without interest, or aggregate
consideration of approximately $413 million. Diodes' offer is backed by fully committed financing from
Bank of America, and the transaction benefits from a high degree of closing certainty within a matter of
days after shareholder approval, with no regulatory approvals required. In agreement with the Board's
conclusion and recommendation, ISS noted (emphasis added):

• 'the terms of the Diodes transaction provide shareholders with the greatest value certainty.'
• 'shareholders might question whether giving up the certainty of the 'bird-in-the-hand' [Diodes Agreement] for an
  offer that may not ever be consummated with Montage is worth the risk.'

We have also communicated that the offer received from Montage Technology Group ('Montage')
suffers from fundamental risks that render it unviable and not in the best interests of Pericom
shareholders, including:

• risks and uncertainties regarding Montage's ability (or unwillingness) to obtain fully committed financing;
• substantial uncertainty surrounding the numerous regulatory approvals required for an acquisition of Pericom;
• Montage's questionable ability to ultimately close a transaction with Pericom in a timely fashion, if at all;
• Pericom's difficulty enforcing any judgment against Montage, a Cayman company with most of its assets in the
  People's Republic of China and few assets in the United States - if for any reason, Montage is unable or unwilling
  to close the proposed transaction with Pericom, the only real recourse for Pericom shareholders may be the
  $43 million reverse break-up fee (vs. $413 million of market premium from Diodes); and

• Montage's erosion of your Board's trust through continued misrepresentations throughout the sales process and then to Pericom shareholders via multiple communications.

ISS AGREES WITH YOUR BOARD - VOTE 'FOR'
THE DIODES AGREEMENT WITH THE WHITE PROXY CARD

The ISS recommendation that shareholders vote the WHITE proxy card at the upcoming Meeting
reinforces what your Board has been advocating for weeks: the certainty and substantial value of the
Diodes offer is superior to the Montage offer. Your Board andISS believe there is too great a risk to
Pericom shareholders that Montage will not be able to close a transaction to acquire Pericom.
ISS, in recommending for the Diodes merger, corroborated what your Board had confidently concluded
and advocated for after thorough evaluation of both offers:

• 'Given the apparent heightened risks, shareholders might question whether giving up the certainty of
  the 'bird-in-the-hand' for an offer that may not ever be consummated with Montage is worth the risk.
  A vote FOR the Diodes transaction as currently structured is warranted.'

Furthermore, ISS expressed the following well-founded criticisms of the Montage offer (emphasis
added):

• 'The verbal confidence in its offer letter that Montage has committed financing, moreover,
  appears to be more style than substance. The CEC commitment letter, for example, 'commits'
  funding over which it nonetheless reserves significant discretion, and which appears to actually be
  contingent upon unspecified conditions…'

• 'The keystone in all of this is the $43 million reverse break-up fee Montage has offered. It may be comforting,
  in the way that closing one's eyes can be comforting when facing an unpleasant reality - but it does nothing
  at all to mitigate that unpleasant reality. A reverse termination fee, because so much smaller than the full merger
  consideration, is probably most effective when the target has the greatest confidence it will never be tapped.
  In this topping bid, by contrast, it simply underscores the heavy risk of a Montage deal breaking.'

As ISS astutely argued, even if Montage were to raise its offer price and substantially improve its
financing commitments (among other necessary improvements), the offer still wouldn't be superior to
Diodes' offer:

• 'It is possible that Montage responds to Diodes' bump by increasing its own bid, tempting Pericom shareholders
  by again increasing the spread between the two deals. But an increase in an offer which still may never be closed i[s]
  far less compelling than the certainty of a good deal which can be closed.'

LOCK IN THE SUBSTANTIAL $17.75 PER SHARE VALUE
YOU DESERVE BY VOTING THE WHITE PROXY CARD TODAY

Your Board urges all Pericom shareholders to vote the WHITE proxy card to lock in the substantial cash
premium represented by the $17.75 per share purchase price offered by Diodes, which we continue to
believe is in the best interests of Pericom shareholders.
We sincerely appreciate and thank you for your continued patience, and we hope to see you at our
upcoming Meeting.

Regards,

Pericom Semiconductor Corporation Board of Directors
