<div align="justify" style="font-size: 10pt; margin-top: 12pt"><b>Note 5 — Fair value measurements</b>
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     As discussed in Note 1, in January 2010 the Company adopted updated accounting guidance which
requires additional disclosure about the amounts of and reasons for significant transfers in and
out of Level 1 and Level 2 fair value measurements. This standard also clarifies existing
disclosure requirements related to the level of disaggregation of fair value measurements for each
class of assets and liabilities and disclosures about inputs and valuation techniques used to
measure fair value for both recurring and nonrecurring Level 2 and Level 3 measurements. Because
this accounting standard only requires enhanced disclosure, the adoption of this standard did not
impact the Company’s financial position or results of operations for the quarter ended June 30,
2010. In addition, effective for interim and annual periods beginning after December 15, 2010, this
standard will require additional disclosure and require an entity to present disaggregated
information about activity in Level 3 fair value measurements on a gross basis, rather than as one
net amount.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     Fair value is defined as the exit price, or the amount that would be received to sell an asset
or paid to transfer a liability in an orderly transaction between market participants as of the
measurement date. There is an established hierarchy for inputs used in measuring fair value that
maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring
that the most observable inputs be used when available. Observable inputs are inputs market
participants would use in valuing the asset or liability and are developed based on market data
obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the
Company’s assumptions about the factors market participants would use in valuing the asset or
liability. The guidance establishes three levels of inputs that may be used to measure fair value:

<div align="justify" style="font-size: 10pt; margin-top: 6pt">     Assets and liabilities are classified based upon the lowest level of input that is significant
to the fair value measurement. The Company reviews the fair value hierarchy on a quarterly basis.
Changes in the observations or valuation inputs may result in a reclassification of levels for
certain securities within the fair value hierarchy.

Deposit Insurance Corporation (“FDIC”) insured corporate bonds and money market funds. When
available, the Company generally uses quoted market prices to determine fair value, and classifies
such items as Level 1. If quoted market prices are not available, prices are determined using
prices for recently traded financial instruments with similar underlying terms as well as directly
or indirectly observable inputs, such as interest rates and yield curves that are observable at
commonly quoted intervals. The Company classifies such items as Level 2.

<div align="justify" style="font-size: 10pt; margin-top: 6pt">     The range of potential contingent consideration that the Company could pay related to the
acquisition of Prodesse was originally between $0 and $25.0 million. This range is tied to multiple
performance measures including commercial and regulatory milestones. To the extent these milestones
are earned, payments of up to $25.0 million in total will be made. The Company will reassess the
fair value of this contingent consideration liability on a quarterly basis. This assessment is
based on a calculation that considers the forecasted achievement of the underlying milestones as of
the date of determination, as well as the timing of the related cash payments, and then discounts
these amounts based on a discount rate the Company determines is appropriate for the underlying
milestones.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     Based on these calculations, the Company initially recorded $18.0 million as of the date of
acquisition as the fair value of this potential contingent consideration liability. The fair value
of this contingent consideration was reduced to $16.2 million as of March 31, 2010 and then further
reduced to $11.9 million as of June 30, 2010. These
reductions were primarily associated with lower anticipated payouts for the related milestones.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     On July 26, 2010, the Company received FDA clearance of its ProFAST™+ assay, thereby
satisfying one of the acquisition-related milestones and triggering a $10.0 million payment to
former Prodesse securityholders, the fair value of which was accrued as of June 30, 2010. The
Company believes future milestone payments, if any, will occur between the fourth quarter of 2010
and the second quarter of 2012.

non-recurring basis include investments in public and private companies, which are described below.

</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     In April 2009, the Company made a $5.0 million preferred stock investment in DiagnoCure, Inc.
(“DiagnoCure”), a publicly-held company traded on the Toronto Stock Exchange. The Company’s equity
investment was initially valued based on the transaction price under the cost method of accounting.
The market value of the underlying common stock is the most observable value of the preferred
stock, but because there is no active market for these preferred shares the Company has classified
its equity investment in DiagnoCure as Level 2 in the fair value hierarchy. The Company’s
investment in DiagnoCure, which totaled $5.0 million as of June 30, 2010, is included in “Licenses,
manufacturing access fees and other assets, net” on the Company’s consolidated balance sheets.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 12pt">     <i>Equity investments in private companies</i>
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     The valuation of investments in non-public companies requires significant management judgment
due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of
such assets. The Company’s equity investments in private companies are initially valued based upon
the transaction price under the cost method of accounting. Equity investments in non-public
companies are classified as Level 3 in the fair value hierarchy.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     In June 2010, in connection with the execution of a collaboration agreement with Pacific
Biosciences of California, Inc., a privately-held sequencing company (“Pacific Biosciences”), the
Company made a $50.0 million preferred stock investment in Pacific Biosciences. The Company’s
investment in Pacific Biosciences, which totaled $50.0 million as of June 30, 2010, is included in
“Licenses, manufacturing access fees and other assets, net” on the Company’s consolidated balance
sheets.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     In September 2009, the Company spun-off its industrial testing assets to Roka, a newly formed
private company. In consideration for the contribution of assets, the Company received shares of
preferred stock representing 19.9% of Roka’s capital stock on a fully diluted basis. The Company’s
investment in Roka totaled approximately $0.7 million as of June 30, 2010, and is also included in
“Licenses, manufacturing access fees and other assets, net” on the Company’s consolidated balance
sheets.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     In 2006, the Company invested in Qualigen, Inc. (“Qualigen”), a private company. The Company’s
investment in Qualigen, which totaled approximately $5.4 million as of June 30, 2010, is also
included in “Licenses, manufacturing access fees and other assets, net” on the Company’s
consolidated balance sheets.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 6pt">     The Company records impairment charges when an investment has experienced a decline that is
deemed to be other-than-temporary. The determination that a decline is other-than-temporary is, in
part, subjective and influenced by many factors. Future adverse changes in market conditions or
poor operating results of investees could result in losses or an inability to recover the carrying
value of the investments, thereby possibly requiring impairment charges in the future. When
assessing investments in private companies for an other-than-temporary decline in value, the
Company considers many factors, including, but not limited to, the following: the share price from
the investee’s latest financing round; the performance of the investee in relation to its own
operating targets and its business plan; the investee’s revenue and cost trends; the investee’s
liquidity and cash position, including its cash burn rate; and market acceptance of the investee’s
products and services. From time to time, the Company may consider third party evaluations or
valuation reports. The Company also considers new products and/or services that the investee may
have forthcoming, any significant news specific to the investee, the investee’s competitors and/or
industry and the outlook of the overall industry in which the investee operates. In the event the
Company’s judgments change as to other-than temporary declines in value, the Company may record an
impairment loss, which could have an adverse effect on its results of operations.
