Innospec Withdraws Proposal to Acquire TPC Group and Announces Special
Dividend of $2 Per Share

LITTLETON, Colo., Dec. 3, 2012 (GLOBE NEWSWIRE) -- Innospec Inc. (Nasdaq:IOSP)
has today announced that its Board of Directors has informed the Board of
Directors of TPC Group (TPCG) that Innospec has withdrawn its proposal to
acquire the company.

Patrick Williams, President and CEO said, "We have spent a great deal of time
and effort studying the TPC business, and, while we still feel that it is a
good fit with Innospec, we are unable to conclude a deal structure in a manner
where we are totally satisfied with the value creation for our shareholders.
As a result, we have reluctantly decided that it would be in our investors'
best interests to withdraw our proposal. Our acquisition strategy has always
been focused on delivering shareholder value, and we continue to pursue other
opportunities which we hope will come to fruition in the coming months."

At the same time, the Board has also declared a special dividend of $2 per
share on each outstanding share of common stock of Innospec Inc. The special
dividend will be paid on December 21, 2012, to shareholders of record at the
close of business on December 14, 2012.

Patrick Williams, continued, "Innospec is a very healthy business, generating
strong cash flows. We have consistently stated that our strategy is to pursue
growth both organically and through acquisitions and this strategy remains
unchanged. And, while the termination of our preliminary proposal to acquire
TPC is unfortunate, our Board has decided to deliver on our commitment to
return cash to shareholders in the form of a special dividend. Our decision to
declare this dividend as a one-time exceptional dividend reflects our desire
to continue to be positioned for acquisitions which will add shareholder value
while our Board considers its option to institute regular annual dividend
and/or stock repurchases in the future."
