CHARLES RIVER AND WUXI FILE REVISED INVESTOR PRESENTATION
Combined Company Expects to Generate Annual Revenue Synergies of
at Least $75 Million to $100 Million by 2013
WILMINGTON, MA and SHANGHAI, CHINA, July 13, 2010— Charles River Laboratories International, Inc.(NYSE: CRL) and WuXi PharmaTech (NYSE:WX) today announced that they have issued an updated investor presentation in connection with Charles River’s proposed acquisition of WuXi. The additional materials include the companies’ expectation that the combined company will generate at least $75 million to $100 million of revenue synergies on an annual basis by 2013. Investors may access the full presentation at Charles River’s website atwww.criver.com/specialwuxi2010.
“We are confident that our proposed combination with WuXi will create not only the world’s premier early-stage contract research organization (CRO), but also significant additional shareholder value,” stated Charles River Chairman, President and Chief Executive Officer James C. Foster. “Among the many metrics that support this view are the estimated revenue synergies we expect to generate from the combination,” he said.
Mr. Foster continued, “This transaction will create the first fully integrated global early-stage CRO, uniquely positioned to address our pharmaceutical and biotechnology clients’ rapidly changing needs and desire for a broader range of global outsourced solutions. Combining Charles River and WuXi will provide a more efficient and cost-effective integrated platform of essential products and services – from molecule creation to first-in-human testing – on a global basis. It is therefore not surprising that even at this early stage, in meeting with our respective existing clients, we are receiving overwhelming support.”
Examples of client responses include the following statements:
From a senior vice president and head of worldwide research of a top-five global pharmaceutical company, “We have great respect for and work with both organizations. When combined with WuXi, Charles River will be able to provide a unique set of end-to-end services which we believe will help accelerate our drug development process. We look forward to working in a more holistic fashion with the combined entity.”
From the senior vice president of research and early development of another top-five pharmaceutical company, “Charles River-WuXi’s unique early-stage portfolio of products and services provides a transformational opportunity for the drug development industry. The availability of a new CRO paradigm will allow companies like us to explore innovative strategic relationships and R&D business models which could dramatically change the R&D productivity equation. We very much look forward to having a company like Charles River-WuXi in the marketplace and to working with the new organization.”

The executive vice president and chief scientific officer of a first-tier biotechnology company said, “The combination of these two companies is the most visionary and promising approach to drug development I’ve seen in this field in the last three decades. To be able to access the power of your integrated drug discovery and early development platform offers us tremendous opportunities to speed affordable and transformational medicine to patients.”
“These remarks, typical of the many comments we have received from other clients, validate our belief that the proposed combination will provide significant benefits to our clients, as well as to our shareholders – including through increased revenue growth. Indeed, as a result of this preliminary client response, we now feel more comfortable in providing investors with greater transparency and quantification of the expected top-line synergies we can generate,” Mr. Foster concluded.
Both Charles River and WuXi urge investors to support the transaction by taking the time to vote promptly by completing and returning the proxy card previously provided or by submitting proxies by telephone or through the Internet.

Investments in toxicology and biology businesses
Moderate labor cost increases
Some volume-based price erosion due to impact of large pharma mergers
Some margin pressure due to depreciation and low utilization of large-scale GMP manufacturing facility
Improving margins driven by business mix shift towards higher-margin services and lean sigma initiative
2010 operating margin reflective of increased SG&A leverage
2011 and 2012 margin trends
Margin turnaround in 2011-2012 driven by:
Contribution from biology and toxicology businesses with little incremental investment
Continuous operational improvements partially offset by direct labor and inflation
Strong improvement in margins forecasted as utilization increases with little incremental investment
Similar trends forecasted in future, albeit at a slower rate
SG&A leverage forecasted to increase as utilization in new businesses such as toxicology and large-scale manufacturing improves

These forward-looking statements, including those with respect to favorable industry trends, guidance for full-year 2010 performance, anticipated strong financial results for 2010 and beyond, and anticipated benefits of the proposed combination with Charles River Laboratories, are not historical facts but instead represent only our belief regarding future events, many of which, by their nature, are inherently uncertain and outside of our control. Our actual results and financial condition and other circumstances may differ, possibly materially, from the anticipated results and financial condition indicated in these forward-looking statements. Risks with respect to the proposed combination include: (i) the possibility that the proposed combination may be delayed or not completed due to the failure to obtain stockholder or regulatory approvals or otherwise satisfy the conditions to the proposed combination as set forth in our acquisition agreement with Charles River; (ii) problems may arise in successfully integrating the businesses of the two companies; (iii) the acquisition may involve unexpected costs; (iv) the combined company may not achieve the anticipated transaction benefits, including improved customer service levels and anticipated cost and revenue synergies, or achieve potential revenue growth and non-GAAP margin expansion; (v) restrictions in our acquisition agreement with Charles River that require us to conduct our business in the ordinary course consistent with past practices and in accordance with other specific limitations may delay or prevent us from taking advantage of business opportunities that may arise prior to the combination; and (vi) the businesses may suffer as a result of uncertainty surrounding the combination. In addition, the businesses may be subject to future regulatory or legislative actions and other risk factors. These other risk factors include: continued uncertainty in the global economy, the pressures being felt by our customers, and pharmaceutical industry consolidation may adversely impact our business and the trends for outsourced R&D and manufacturing for longer than expected or more severely than expected; we may be unable to successfully make our planned investments and capital expenditures on a timely basis, these investments may not yield the desired results, and we may need to modify the nature and level of our investments and capital expenditures; pharmaceutical companies may not change their business models as expected or in a manner favorable to us; we may fail to capitalize on the opportunities presented; and we may not maintain our preferred provider status with our clients and may be unable to successfully expand our capabilities to meet client needs. In addition, other factors that could cause our actual results to differ from what we currently anticipate include failure to generate sufficient future cash flows or to secure any required future financing on acceptable terms or at all; failure to retain key personnel; effective integration of continuing products and services from AppTec; our reliance on a limited number of customers to continue to account for a high percentage of our revenues; risk of payment failure by any of our large customers, which could significantly harm our cash flows and profitability; dependence upon the continued service of our senior management and key scientific personnel; and our ability to retain our existing customers or expand our customer base.
