The Company completed a financing during the quarter, whereby the Company
will issue 1.25 million shares at $10.08 per share. The Company had a cash
balance of approximately $15.5 million on October 31, 1997.

"The first quarter was significant for Metrowerks, as revenues from the
embedded and windows markets totaled 75 percent of total revenues for the
quarter," said Jean Belanger, Metrowerks CEO and Chairman of the Board.
"Moreover, we maintained strong revenue growth while increasing our
profitability."

The Company has two main revenue streams; the sale of shrink-wrapped
software, or product revenues, and product agreement revenues, whereby
companies pay Metrowerks to support their platforms. Product revenues for
Q1FYJuly98 comprised 74 percent of total revenues, or $4.53 million.

Cost of goods sold for Q1FYJuly98 were 18% of net revenues compared to 17%
for Q4FYJuly97. In Q1FYJuly98, R&D expenses totaled US$2.1 million as
compared to US$2.3 million in Q4FYJuly97. R&D expenses were down slightly

consultants are needed for development projects. SG&A and technical support
expenses totaled US$2.37 million in Q1FYJuly98 and US$2.44 million in
Q4FYJuly97. SG&A expenses were down slightly, as the Company increased its
