                  Octel Corp. Reports 1st Quarter 2003 Results

NEWARK, DELAWARE, April 28, 2003 - Octel Corp. (NYSE: OTL) today announced
financial results for the first quarter ended March 31, 2003.

                                 - Highlights -

                . Net income of $0.88 per share for the quarter
                . Specialty Chemicals sales up 8% over last year
                . Restructuring activities in line with plan

Net income for the first quarter of 2003 was $10.9 million or $0.88 per share
compared with a profit of $18.4 million or $1.47 per share in the comparable
period last year.

TEL (tetraethyl lead) sales were $47.8 million, 26% below the same period last
year on volumes 32% down. The political situation in Venezuela that was
highlighted last quarter impacted the first quarter's results with no shipments
to that region. Deliveries have since resumed in April 2003. Selling prices
overall were well managed and reduced the impact of the global market volume
decline. Price increases and continued strong cost control at our UK plant
resulted in gross profit for the first quarter of $24.0 million or 50.2% of
sales.

Sales in Specialty Chemicals were $49.9 million, an 8% increase over the first
quarter of 2002. Gross profit for the quarter of $16.0 million was marginally
down on last year by $0.7 million or 4.2% due to the reduced profitability of
our detergent business.

As planned, overall operating expenses of $18.4 million were $1.1 million higher
than last year reflecting our continued investment in infrastructure to support
the growing Specialty Chemicals segment.

Cash flow from operating activities was $5.5 million for the first quarter of
2003. As was discussed last quarter, this was impacted by the political
situation in Venezuela and the consequent loss of fourth quarter 2002 and first
quarter 2003 shipments. As a result, the bank debt repayments scheduled for the
early part of 2003 have been rescheduled to later this year and next.

In 2002 we made provisions for restructuring costs of $19.5 million, the
majority of which related to the Specialty Chemicals business. There were no
additions to the provision in the first quarter of 2003 although it is still
expected that aggregate further charges of $20 million will be incurred during
the remainder of 2003 and 2004.



These additional charges will reflect our stated objectives of being proactive
in managing the continuing decline in demand for TEL and the rationalization of
sites and assets to capture synergies in Specialty Chemicals.

Commenting on the results, Dennis Kerrison, President and Chief Executive
Officer, said, "TEL had a good quarter considering the absence of deliveries to
Venezuela. It is encouraging to report that the position in the country has now
improved and deliveries have resumed this month. Our plans to further reduce
capacity at Ellesmere Port in line with future demand have now been finalized
and will be completed by early 2004. This continues our stated intent to manage
the capacity required to support the continuing decline in TEL demand."

"Specialty Chemicals results were a little better than expected and are starting
to reflect the results of management actions taken late last year and early
2003. The benefits of strengthening the management team and a more focused
approach to the market place are starting to come through but will be seen more
fully later in the year and 2004 as has been previously stated. The
restructuring steps announced in the second half of last year have been
implemented with further actions to be taken during the remainder of this year."

"The first quarter results were only marginally below expectations despite the
shortfall from Venezuela. With our customer in that country now back on stream
and improving results from the Specialty Chemicals operations, we are looking
forward to a successful 2003."
