Joint Safe Harbor

Remarks that we make during this call about future expectations, plans and prospects may include forward-looking statements. There are risks and uncertainties that could cause actual results or outcomes to differ materially from those contemplated by the forward-looking statements, as a result of various important factors, including those that are discussed in QIAGEN’s and DIGENE’s most recent filings with the SEC, and the risks related to the transaction itself. Please refer to those filings, which are publicly available on the SEC’s website, for a full description of those factors. In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use the non-GAAP financial measures “adjusted EPS,” “adjusted operating income,” “adjusted net income,” “adjusted operating margin” and “EBITDA”. None of these financial measures is a measure of operating performance under GAAP. We believe that the use of these non-GAAP measures helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts. When analyzing our operating performance, investors should not consider these non-GAAP measures as a substitute for diluted EPS, income from operations, net income, or operating margin prepared in accordance with GAAP.

In the attached presentation, QIAGEN will use the term molecular diagnostics. The use of this term in reference to certain countries, such as the United States, is limited to products subject to regulatory framework. Current QIAGEN molecular diagnostics products are 34 EU CE IVD assays, six EU CE IVD sample preparation products, one 510k PAX RNA product, nine China SFDA IVD assays and 98 general purpose reagents

A Critical Disease Target: Humanpapilloma Virus (HPV)

Cervical cancer is the #2 cancer for women worldwide

WW over 470K cases/year causing more than 230K deaths

In the US almost 10K cases/year, almost 4K deaths

One woman dies every two minutes from cervical cancer

HPV is the proven cause of cervical cancer

The DIGENE HPV Test is the emerging “standard of care” for cervical cancer screening

Extensive and expanding clinical data

Medical community support – recognized in major clinical guidelines

Well established reimbursement

Strong partnerships with major reference labs

Pool of “eligible” candidates for the DIGENE HPV Test is large and broadly untapped

DIGENE HPV Test is Playing a Key Role in Women’s Health

Cervical cancer is more prevalent in women age >30

1/3 of cervical cancers in woman with a normal Pap

Clinical practice guidelines now recommend combined screening (HPV+Pap for women >30 yrs)

The DIGENE HPV Test

Clinical results published on > 200,000 women

First FDA-approval received in 1999

ACOG Guidelines cites studies showing

HPV testing sensitivity up to 100% for CIN 2/3 and cancer (cervical intra-epithelial neoplasia)

Cites studies showing liquid-based cytology may miss 15-35% of CIN 2/3 and cancer

Combined HPV testing with cervical cytology has a negative predictive value for CIN 2/3 of 99-100%

HPV Screening Can Best Fight Cervical Cancer

QIAGEN and Digene caution readers that any forward-looking information is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking information. These include risks and uncertainties relating to: the ability to obtain regulatory approvals of the transaction on the proposed terms and schedule; the parties may be unable to complete the transaction because conditions to the closing of the transaction may not be satisfied; the risk that the businesses will not be integrated successfully; the transaction may involve unexpected costs or unexpected liabilities; the risk that the cost savings and any other synergies from the transaction may not be fully realized or may take longer to realize than expected; disruption from the transaction making it more difficult to maintain relationships with customers, employees or suppliers; competition and its effect on pricing, spending, third-party relationships and revenues; the need to develop new products and adapt to significant technological change; implementation of strategies for improving internal growth; use and protection of intellectual property; realization of potential future savings from new productivity initiatives; general worldwide economic conditions and related uncertainties; future legislative, regulatory, or tax changes as well as other economic, business and/or competitive factors; and the effect of exchange rate fluctuations on international operations. In addition, the transaction will require the combined company to obtain significant financing. The combined company’s liquidity and results of operations could be materially adversely affected if such financing is not available on favorable terms.

Moreover, the substantial leverage resulting from such financing will subject the combined company’s business to additional risks and uncertainties. The risks included above are not exhaustive. The most recent reports on Form 20-F, Form 6-K and other periodic reports filed with or furnished to the Securities and Exchange Commission by QIAGEN and the most recent reports on Form 10-K, Form 10-Q, Form 8-K and other periodic reports filed by Digene with the Securities and Exchange Commission contain additional factors that could impact the combined company’s businesses and financial performance. The parties expressly disclaim any obligation or undertaking to release publicly any updates or revisions to any such statements to reflect any change in the parties’ expectations or any change in events, conditions or circumstances on which any such statement is based.

Additional Information

QIAGEN is filing today a Current Report on Form 6-K that will include as exhibits the Agreement and Plan of Merger among QIAGEN, QIAGEN North American Holdings, Inc., QIAGEN’s merger subsidiary and Digene Corporation. QIAGEN intends to file a Registration Statement on Form F-4 and a Schedule TO, and Digene plans to file a Solicitation/Recommendation Statement on Schedule 14D-9, with the Securities and Exchange Commission in connection with the transaction. QIAGEN and Digene expect to mail a Prospectus, which is part of the Registration Statement on Form F-4, the Solicitation/Recommendation Statement on Schedule 14D-9 and related exchange offer materials, including a letter of election and transmittal, to shareholders of Digene upon commencement of


the exchange offer. These documents contain important information about the transaction and should be read before any decision is made with respect to the exchange offer. Investors and stockholders will be able to obtain free copies of these documents through the website maintained by the Securities and Exchange Commission at www.sec.gov. Free copies of these documents may also be obtained from QIAGEN, by directing a request to QIAGEN’s IR department at QIAGEN Strasse 1, 40724 Hilden, Germany, or from Digene, by directing a request to Digene at 1201 Clopper Road, Gaithersburg, MD, 20878.

You may read and copy any reports, statements or other information filed or furnished by QIAGEN or Digene at the SEC’s Public Reference Room at Station Place, 100 F Street, N.E., Washington, D.C. 20549. You can request copies of these documents by writing to the SEC and paying a fee for the copying cost.

QIAGEN’s and Digene’s SEC filings are also available to the public at the SEC’s web site at http://www.sec.gov, or at their web sites at www.qiagen.com or www.digene.com.

Use of Non-GAAP Financial Measures

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use the non-GAAP financial measures “adjusted EPS,” “adjusted operating income,” “adjusted net income,” “adjusted operating margin” and “EBITDA” (net earnings before interest, taxes, depreciation and amortization expense). None of these financial measures is a measure of operating performance under GAAP. We believe that the use of these non-GAAP measures helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts. When analyzing our operating performance, investors should not consider these non-GAAP measures as a substitute for diluted EPS, income form operations, net income, or operating margin prepared in accordance with GAAP.
