<div align="left" style="font-size: 10pt; margin-top: 10pt">       At June 30, 2010, the Company believes that the unrealized losses on its available-for-sale
investments are temporary. The investments with unrealized losses consist primarily of corporate
debt securities and an auction rate security. In making the determination that the decline in fair
value of these securities was temporary, the Company considered various factors, including but not
limited to: the length of time each security was in an unrealized loss position; the extent to
which fair value was less than cost; financial condition and near term prospects of the issuers;
and the Company’s intent not to sell these securities and the assessment that it is more likely
than not that the Company would not be required to sell these securities before the recovery of
their amortized cost basis.
</div>
<div align="left" style="font-size: 10pt; margin-top: 10pt">       The Company’s strategic equity investments include common stock in public companies with which
the Company has or had a collaborative arrangement with.
The Company also has an $8.0 million investment in a collaborative
partner, Acceleron Pharma, Inc. (“Acceleron”), which is
recorded within “Other assets” in the accompanying
condensed consolidated balance sheets at June 30, 2010 and March 31,
2010. The Company accounts for its investment in Acceleron under the
cost method as Acceleron is a privately-held company over which the
Company does not exercise significant influence. The Company will
continue to monitor this investment to evaluate whether any decline
in its value has occurred that would be other-than-temporary, based
on the implied value from any recent rounds of financing completed by
Acceleron, market prices of comparable public companies and general
market conditions.
