testing, its business, operations, operational trends, financial statements, markets and present and

operating plans, budgets and forecasts and reports of actual operations compared thereto),

conversations and connections with other corporate officers and employees, attendance at

management and Board of Directors meetings and committees thereof and via reports and other

information provided to them in connection therewith.

16. It is appropriate to treat the Individual Defendants as a group for pleading

purposes and to presume that the false , misleading and incomplete information conveyed in the

Company's public filings , press releases and other publications as alleged herein are the

collective actions of the narrowly defined group of defendants identified above. Each of the

above officers of Schering-Plough, by virtue of their high-level positions with the Company,

directly participated in the management of the Company, was directly involved in the day-to-day

operations of the Company at the highest levels and was privy to confidential proprietary

information concerning the Company and its business , operations , products , growth, financial

statements, and financial condition, as alleged herein. Said defendants were involved in drafting,

producing, reviewing and/or disseminating the false and misleading statements and information

alleged herein, were aware, or recklessly disregarded, that the false and misleading statements

were being issued regarding the Company, and approved or ratified these statements, in violation

of the federal securities laws.

17. As officers and controlling persons of a publicly-held company whose common

stock was, and is, registered with the SEC pursuant to the Exchange Act, and was traded on the

New York Stock Exchange (the "NYSE ), and governed by the provisions of the federal

securities laws, the Individual Defendants each had a duty to disseminate promptly, accurate and

truthful information with respect to the Company's drug products and drug testing, its business,

financial condition and performance, growth, operations, financial statements, markets,

management, earnings and present and future business prospects, and to correct any previously-

issued statements that had become materially misleading or untrue, so that the market price of

the Company's publicly-traded common stock would be based upon truthful and accurate

Page 6: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 6 of 63

information. The Individual Defendants' misrepresentations and omissions during the Class

Period violated these specific requirements and obligations.

18. The Individual Defendants participated in the drafting, preparation, and/or

approval of the various public and shareholder and investor reports and other communications

complained of herein and were aware of, or recklessly disregarded, the misstatements contained

therein and omissions therefrom, and were aware of their materially false and misleading nature.

Because of their Board membership and/or executive and managerial positions with Schering-

Plough, each of the Individual Defendants had access to the adverse undisclosed information

about Schering-Plough's business prospects and financial condition and performance as

particularized herein and knew (or recklessly disregarded) that these adverse facts rendered the

positive representations made by or about Schering-Plough and its business issued or adopted by

the Company materially false and misleading.

19. The Individual Defendants, because of their positions of control and authority as

officers and/or directors of the Company, were able to and did control the content of the various

SEC filings, press releases and other public statements pertaining to the Company during the

Class Period. Each Individual Defendant was provided with copies of the documents alleged

herein to be misleading prior to or shortly after their issuance and/or had the ability and/or

opportunity to prevent their issuance or cause them to be corrected. Accordingly, each of the

Individual Defendants is responsible for the accuracy of the public reports and releases detailed

herein and is therefore primarily liable for the representations contained therein.

20. Each of the defendants is liable as a participant in a fraudulent scheme and course

ofbusiness that operated as a fraud or deceit on purchasers of Schering-Plough common stock by

disseminating materially false and misleading statements and/or concealing material adverse

facts. The scheme: (i) deceived the investing public regarding Schering-Plough's business,

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 7 of 63

operations, management and the intrinsic value of Schering-Plough common stock; (ii) enabled

defendants to artificially inflate the price of Schering-Plough shares; (iii) enabled Schering-

Plough insiders to sell almost $45 million of their privately held Schering-Plough shares and it

allowed the Company itself to register and sell over $1.6 billion in newly issued common stock

during the Class Period and while in possession of material adverse non-public information

about the Company; and (iv) caused plaintiff and other members of the Class to purchase

Schering-Plough common stock at artificially inflated prices.

PLAINTIFF'S CLASS ACTION ALLEGATIONS

21. Plaintiff brings this action as a class action pursuant to Federal Rule of Civil

Procedure 23(a) and (b)(3) on behalf of a Class, consisting of all those who purchased or

otherwise acquired the common stock of Schering-Plough between July 24, 2006 and January

14, 2008, inclusive (the "Class ) and who were damaged thereby. Excluded from the Class are

defendants, the officers and directors of the Company, at all relevant times, members of their

immediate families and their legal representatives , heirs, successors or assigns and any entity in

which defendants have or had a controlling interest.

22. The members of the Class are so numerous that joinder of all members is

impracticable. Throughout the Class Period, Schering-Plough common shares were actively

traded on the NYSE. As of September 30, 2007, the Company had over 1.619 billion shares of

common stock issued and outstanding. While the exact number of Class members is unknown to

plaintiff at this time and can only be ascertained through appropriate discovery, plaintiff believes

that there are thousands of members in the proposed Class. Record owners and other members

of the Class may be identified from records maintained by Schering-Plough or its transfer agent

and may be notified of the pendency of this action by mail, using the form of notice similar to

that customarily used in securities class actions.

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 8 of 63

23. Plaintiff s claims are typical of the claims of the members of the Class as all

members of the Class are similarly affected by defendants' wrongful conduct in violation of

federal law that is complained of herein.

24. Plaintiff will fairly and adequately protect the interests of the members of the

Class and has retained counsel competent and experienced in class and securities litigation.

25. Common questions of law and fact exist as to all members of the Class and

predominate over any questions solely affecting individual members of the Class. Among the

questions of law and fact common to the Class are:

(a) whether the federal securities laws were violated by defendants' acts as

alleged herein;

(b) whether statements made by defendants to the investing public during the

Class Period misrepresented material facts about the business, operations and management of

Schering-Plough; and

(c) to what extent the members of the Class have sustained damages and the

proper measure of damages.

26. A class action is superior to all other available methods for the fair and efficient

adjudication of this controversy since joinder of all members is impracticable. Furthermore, as

the damages suffered by individual Class members may be relatively small, the expense and

burden of individual litigation make it impossible for members of the Class to individually

redress the wrongs done to them. There will be no difficulty in the management of this action as

a class action.

SUBSTANTIVE ALLEGATIONS

Defendants ' Materially False and MisleadingStatements Made During the Class Period

27. 2Q:06 Results Announced . On July 24, 2006, the inception of the Class Period,

defendants published a release on PR Newswire announcing purported results for the second

quarter of 2006, the period ended June 30, 2006. This release also announced the purported

success of the Company's "Turnaround plan, began at the end of 2003. and contained

statements regarding the purported success of its VYTORIN and ZETIA product sales , in part, as

follows:

Schering-Plough Reports Financial Results for 2006 Second QuarterTurnaround Phase of Action Agenda Well Under Way

KENILWORTH, N.J., July 24 /PRNewswire -FirstCall/ -- Schering-PloughCorporation (NYSE: SGP) today reported financial results for the 2006 secondquarter.

"Schering-Plough is executing on its six- to eight-year strategic plan that we laidout in 2003, said Fred Hassan, chairman and CEO. "Our Turnaround is wellunder way. We have been growing faster than our peers since the beginning of2005. Higher top-line sales performance, reinforced by financial discipline,continues to drive higher bottom-line earnings. And we are stepping up our effortsto build depth and strength for the long term, especially in R&D.

For the 2006 second quarter, the company reported net income available tocommon shareholders of $237 million or 16 cents per share on a GAAP basis.Excluding charges related to actions to streamline the company's manufacturingoperations announced June 1, 2006 (see table below), the company's income inthe 2006 second quarter would have been $375 million or 25 cents per share.

For the 2005 second quarter, the company reported a loss of $70 million or 5cents per share on a GAAP basis, which included special charges of $259 millionor approximately 18 cents per share.

GAAP net sales for the 2006 second quarter totaled $2.8 billion, up 11 percentversus the 2005 second quarter. Schering-Plough does not record sales of itscholesterol joint venture with Merck & Co., Inc., as the venture is accounted forunder the equity method . Including an adjustment of an assumed 50 percent ofglobal cholesterol joint venture net sales (see table below), Schering-Plough'sadjusted net sales for the 2006 second quarter would have totaled $3.3 billion, an

9

18 percent increase, compared to $2.8 billion on a similar adjusted basis in the2005 second quarter.

The cholesterol franchise, managed through a joint venture with Merck,comprises VYTORIN (ezetimibe/simvastatin) and ZETIA (ezetimibe).VYTORIN has been launched in more than 35 countries and ZETIA in more than80.

"While the U.S. cholesterol-lowering market adjusts to the entry of generic Zocorcompetition, we remain confident in the value proposition afforded by VYTORINand ZETIA, said Hassan. The company pointed to head-to-head clinical trialsversus Crestor, Lipitor and Zocor that have shown VYTORIN to be the mosteffective medicine for lowering cholesterol and getting patients to moreaggressive treatment goals. Further, new recommendations from the AmericanHeart Association and the American College of Cardiology are calling forincreasingly aggressive treatment of high cholesterol for certain patients."VYTORIN and ZETIA are valuable tools for doctors seeking to get their patientsto goal, Hassan said, "with VYTORIN offering the added benefit of being ableto get more patients to goal at the initial starting dose.

The company continues to direct significant investments in R&D to advance theproduct pipeline and build long-term strength, particularly in drug development.

The company noted that GAAP net sales do not include sales of the cholesterolproducts marketed in partnership with Merck, as described below . Globalcholesterol joint venture net sales , which include VYTORIN and ZETIA, totaledapproximately $958 million in the 2006 second quarter compared to net sales of$514 million in the comparable 2005 period . Including an adjustment of anassumed 50 percent of global cholesterol joint venture net sales , Schering-Plough's adjusted net sales for the second quarter of 2006 would have totaled $3.3billion, an 18 percent increase , as compared to $2.8 billion on a similar adjustedbasis in the second quarter of 2005.

The company utilizes the equity method of accounting for its cholesterol jointventure with Merck. Overall, the company shares in approximately 50 percent ofthe profits of the joint venture with Merck, although there are different profit-sharing arrangements for the cholesterol products in countries around the world.There is a separate co-marketing agreement with Bayer for ZETIA in Japan,where the product is currently under regulatory review. Under the equity method,the company records its share of the income from operations (which includesmilestones earned from Merck) in "Equity income from cholesterol jointventure, which totaled $355 million in the 2006 second quarter versus $170million in the second quarter of 2005. The increase in equity income reflected the

strong sales of VYTORIN and ZETIA in the 2006 second quarter, which werefavorably impacted by a modest increase in U. S. trade inventory buying patterns.

28. 2Q:06 Form 10-Q. On or about July 28, 2006, defendants filed with the SEC the

Company's 2Q:06 Form 10-Q, for the quarter ended June 30, 2006, signed by defendant Koehler

and certified by defendants Hassan and Bertolini. In addition to making substantially similar

statements concerning the Company' s operations , financial results , and the progress of its

turnaround plan and its marketing of VYTORIN and ZETIA as had been published previously,

the 2Q:06 Form 10-Q also contained representations which attested to the purported

effectiveness and sufficiency of the Company's controls and procedures, as follows:

Item 4. Controls and Procedures

Management, including the chief executive officer and the chief financial officer,has evaluated the Company's disclosure controls and procedures as of the end ofthe quarterly period covered by this Form 10-Q and has concluded that theCompany's disclosure controls and procedures are effective. They also concludedthat there were no changes in the Company's internal control over financialreporting that occurred during the Company's most recent fiscal quarter that havematerially affected, or are reasonably likely to materially affect, the Company'sinternal control over financial reporting.

As part of the changing business environment in which the Company operates, theCompany is replacing and upgrading a number of information systems. Thisprocess will be ongoing for several years. In connection with these changes, aspart of the Company's management of both internal control over financialreporting and disclosure controls and procedures, management has concluded thatthe new systems are at least as effective with respect to those controls as the priorsystems.

29. Certifications . In addition to the foregoing, the Company's 2Q:06 Form 10-Q

also contained Certifications by defendants Hassan and Bertolini , that attested to the purported

accuracy and completeness of the Company' s financial and operational reports , as follows:

that Schering-Plough was operating according to plan, or that Schering-Plough could achieve

guidance sponsored and/or endorsed by defendants.

Describing the Build the Base phase, Hassan said, "We will be honing our edge --in people, products and processes. We will be getting even more from what wehave. And we will be extending our core -- to new patients, new customers, newmarkets. We will be investing to advance important new treatments in ourpipeline through phases II and III. We have built a strong engine. Now we'regoing to let it run.

Hassan made these comments in conjunction with the company's announcementof third quarter 2006 sales and earnings results. He referred to the five- phaseAction Agenda, which is the six- to eight-year plan for transforming Schering-Plough announced in the spring of 2003.

We have been thefastest-growing company in our peer group for the past year. Our people aremotivated and engaged. They are building toward our goal of sustainable highperformance.

For the 2006 third quarter, the company reported net income available to commonshareholders of $287 million or 19 cents per share on a GAAP basis. For the 2005third quarter, the company reported net income of $43 million or 3 cents per shareon a GAAP basis.

Hassan also commented on the critical importance of organizational health toperformance. "We recently did a benchmarked diagnostic of our organizationalhealth with the people who know it best -- our own employees, worldwide. Onmeasures of engagement, on trust in management, on recommending Schering-Plough as a good place to work, we benchmarked strongly against high-performance companies across all global industries. This is very importantinformation, because organizational health is a leading indicator of futureperformance. Added Hassan, "We also learned that our people see businessintegrity as a competitive advantage. This is what we mean when we say we areforging a high-performance culture.

"We are pleased that sales of our cholesterol joint venture have continued to growthis year, even with the U. S. introduction of new generic statins , said Hassan

Schering-Plough obtained FDA approval for ZETIA in 2002, and the medicationhas been approved in 90 countries worldwide. The cholesterol - managementmarket is one of the largest worldwide , with total global sales of $34 billion andsales in the United States of $22 billion in 2006 (IMS Health).

England. At this conference, defendants reiterated many of the same or similar materially false

and misleading statements as had been published by defendants previously. This conference was

also broadcast live on the Internet in a widely disseminated webcast. Similarly, on November

13, 2007, defendant Bertolini also presented at the 2007 Credit Suisse Health Care Conference in

Phoenix, Ariz., where he too reiterated many of the same or similar materially false and

misleading statements as are reported herein, supra.

55. 3Q:07 Results Announced . On October 22, 2007, defendants published a release

on PR Newswire announcing purported results for the third quarter of 2007, the period ended

September 30, 2007. This release again reported the purported success of the Company's

turnaround plan and its VYTORIN and ZETIA product sales , in part, as follows:

Schering-Plough Financial Results for Third Quarter of 2007; SolidPerformance Continues in Third Quarter of 2007; Company Prepares forIntegration of Organon BioSciences

KENILWORTH, N.J., Oct. 22 /PRNewswire-FirstCall/ -- Schering-PloughCorporation today reported financial results for the third quarter of 2007 andcommented on its planned acquisition of Organon BioSciences N.V. (OBS),which includes the Organon human health business and Intervet animal healthbusiness.

"Schering-Plough now recorded its 12th consecutive quarter of double- digitadjusted sales growth, said Fred Hassan, chairman and CEO. "Schering- Plough`s long-term strategy continues to unfold. Our strategy to grow the top line,exercise financial discipline and expand our R&D pipeline again delivered strongresults.

Added Hassan: "Our focus on building R&D excellence is beginning to bear fiuit.With the upcoming acquisition of Organon BioSciences, we will have a total of12 significant projects in Phase III -- we will have a pipeline with a Phase IIIbulge. This, combined with relatively long exclusivity of our marketed productportfolio, puts Schering-Plough in a substantially stronger position in terms of itslate-stage pipeline and portfolio than only four years ago, said Hassan.

For the 2007 third quarter, Schering-Plough reported net income available tocommon shareholders of $713 million or 45 cents per common share on a GAAPbasis. Excluding acquisition-related items and an upfront R&D payment, earningsper share for the 2007 third quarter would have been 28 cents (see table below onpage 13). For the 2006 third quarter, Schering-Plough reported net income of$287 million or 19 cents per common share on a GAAP basis.

36

Page 37: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 37 of 63

Net sales for the 2007 third quarter rose 9 percent on a GAAP basis and 12percent on an adjusted basis versus the 2006 period . GAAP net sales for the 2007third quarter totaled $2.8 billion ; adjusted net sales , which includes an assumed 50percent of global cholesterol joint venture net sales (see table below on page 12and hereinafter referred to as "adjusted sales ) for the 2007 third quarter wouldhave totaled $3.5 billion compared to $3.1 billion on a similar adjusted basis inthe 2006 third quarter. Schering-Plough does not record sales of its cholesteroljoint venture with Merck & Co., Inc . (Merck), as the venture is accounted forunder the equity method.

GAAP net sales for the 2007 third quarter totaled $2.8 billion , up 9 percent ascompared to the third quarter of 2006 . The sales growth reflects a 3 percentfavorable impact from foreign exchange and a 2 percent unfavorable impactrelated to the reversal of accrued rebates in the 2006 third quarter for theTRICARE Retail Pharmacy Program in the United States.

Global cholesterol joint venture net sales , which include VYTORIN and ZETIA,totaled $ 1.3 billion in the 2007 third quarter, a 26 percent increase compared tonet sales of $ 1.0 billion in the comparable 2006 period . Schering-Plough does notrecord sales of its cholesterol joint venture with Merck as the venture is accountedfor under the equity method . Including an adjustment of an assumed 50 percent ofthe global cholesterol joint venture net sales , Schering-Plough ' s adjusted sales forthe 2007 third quarter would have been $3 . 5 billion, a 12 percent increase,compared to $3.1 billion on a similar adjusted basis in the 2006 third quarter.

56. 3Q:07 Form 10-Q. On or about October 26, 2007, defendants filed with the SEC

the Company's 3Q:07 Form 10-Q, for the quarter ended September 30, 2007, signed by

defendant Koehler and certified by defendants Hassan and Bertolini. In addition to making

substantially similar statements concerning the Company' s operations , financial results , and the

progress of its turnaround plan and its marketing of VYTORIN and ZETIA as had been

published previously, the 3Q:07 Form 10-Q also contained representations which attested to the

purported effectiveness and sufficiency of the Company's controls and procedures, as follows:

Item 4. Controls and Procedures

Management, including the chief executive officer and the chief financial officer,has evaluated Schering-Plough's disclosure controls and procedures as of the endof the quarterly period covered by this 10-Q and has concluded that Schering-

37

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 38 of 63

Plough's disclosure controls and procedures are effective. They also concludedthat there were no changes in Schering-Plough's internal control over financialreporting that occurred during Schering-Plough's most recent fiscal quarter thathave materially affected, or are reasonably likely to materially affect, Schering-Plough's internal control over financial reporting.

As part of the changing business environment in which Schering-Plough operates,Schering-Plough is replacing and upgrading a number of information systems.This process will be ongoing for several years. In connection with these changes,as part of Schering-Plough's management of both internal control over financialreporting and disclosure controls and procedures, management has concluded thatthe new systems are at least as effective with respect to those controls as the priorsystems. An example of a change in information systems that occurred during thefirst nine months of 2007 is the replacement of Schering-Plough's system forconsolidation and reporting.

57. Certifications . In addition to the foregoing, the Company's 3Q:07 Form 10-Q

also contained Certifications by defendants Hassan and Bertolini , that attested to the purported

accuracy and completeness of the Company' s financial and operational reports, as follows:

58. On January 3, 2008, defendant Hassan and Schering-Plough presented at the

Morgan Stanley Pharmaceutical CEOs Unplugged Conference, that was also broadcast live on

the Internet in a widely disseminated webcast. At this conference, defendants reiterated many of

the same or similar materially false and misleading statements as had been published by

defendants previously. Moreover, when announcing Hassan and the Company's participation,

defendants also published a release that stated, in part, the following:

Schering-Plough to Webcast Presentation at Morgan Stanley PharmaceuticalCEOs Unplugged Conference

KENILWORTH, N.J., Dec. 27 /PRNewswire-FirstCall/ -- Schering-PloughCorporation (NYSE: SGP) will provide a live audio webcast of an informalpresentation by Fred Hassan, chairman and chief executive officer, followed by aquestion-and-answer session, at the Morgan Stanley Pharmaceutical CEOsUnplugged Conference on Jan. 3, 2008, at approximately 8:45 a.m. (ET). MorganStanley hosts will moderate the informal "unplugged presentation.

Included in Mr. Hassan's comments will be Schering-Plough's strategic evolutionand the acquisition of Organon BioSciences N.V. (OBS). During the conferencehe may confirm that the company is still targeting the same accretion and synergytargets mentioned when the OBS acquisition was announced March 12, 2007,

specifically that the transaction is anticipated to be accretive to Schering-Plough'searnings per share by about 10 cents in the first full year, excluding purchase-accounting adjustments and acquisition- related costs; and Schering-Ploughexpects to achieve annual synergies of $500 million. It is expected to take threeyears from the closing to reach this level of synergies.

Hassan may also reaffirm the following items as disclosed in previous Securitiesand Exchange Commission filings:

• Schering-Plough anticipates that sales from VYTORIN and ZETIA willcontinue to grow in the fourth quarter of 2007 and in 2008;

• Schering-Plough is confident in its key products; however, these products facegrowing competition. Schering-Plough will invest in its key brands to sustaintheir leadership position;

59. The statements made by defendants at the Merrill Lynch conference, at the Credit

Suisse conference and at the Morgan Stanley conference as well as those statements contained in

Schering-Plough's October 22, 2007 release and and/or contained in the 3Q:07 Form 10-Q,

referenced above, were each materially false and misleading when made and were known by

defendants to be false at that time, or were recklessly disregarded as such thereby, for the reasons

stated herein in ¶ 33, supra.

THE TRUE FINANCIAL AND OPERATIONAL CONDITIONOF SCHERING-PLOUGH IS BELATED DISCLOSED

60. On January 14, 2008 , investors were shocked and alarmed after it was revealed,

for the first time, that not only were there severe safety and efficacy issues related to the

Company's sale of VYTORIN, but that defendants had purposefully delayed the publication of a

study that they possessed throughout the Class Period that demonstrated that VYTORIN was

neither safe nor effective . That day, Fortune.com reported, in part, the following:

Merck, Schering Study Falls Flat

The wait was long but the result is out. Vytorin failed.

Shares of drugmakers Merck and Schering-Plough dropped 2.0%, to $59.32, and5.9%, to $26.09, respectively, on Monday morning, after a long-delayed study

40

Page 41: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 41 of 63

found that high cholesterol patients fared no better taking Vytorin over the genericform of Zocor (See "Long-Delayed Vytorin Study Fails ).

Forbes.com had previously reported that the study, Enhance, had been delayed

for eighteen months, raising expectations among some cardiologists of a

negative result. (See "The Vytorin Question") The House Committee on Energy

and Commerce has started an investigation into the delay.

Enhance focused on a group of 720 patients with a rare condition that made themsusceptible to high cholesterol . The patients were given either Vytorin, or a highdose of generic Zocor, known as simvastatin . Vytorin itself is a combination ofSchering-Plough ' s Zetia and Merck's Zocor, which lost patent protection in 2006.

Vytorin and its sister pill Zetia generate $5 billion in sales annually for Merck,based in Whitehouse Station, N.J., and Schering-Plough. The medicines aretaken by millions of people; Vytorin lowers low-density liproprotein (LDL) morethan any other single pill. But the study raises questions about whether it has thesame benefits as other cholesterol drugs such as Lipitor from Pfizer, and Crestorfrom AstraZeneca.

Patients on Vytorin actually had more heart attacks, cardiovascular deaths, andheart procedures than those who were on Zocor, according to the Enhancestudy.... Patients on Vytorin actually ended the study with slightly more plaquein their arteries....

Still, the negative result is likely to result in further scrutiny of Merck andSchering-Plough. Drug safety advocates and others have called for studies to beput in the public domain more quickly. The long delay to getting the Enhancestudy out is likely to raise questions about how much control drug companiesshould have over the conduct oftheir clinical trials.

Earlier in January, Merck Chief Executive Richard Clark said he expectedVytorin to keep a secure position in the cholesterol drug market and citedseveral other ongoing studies in addition to this one [Emphasis added.]

61. Moreover, the following day, shares of the Company continued to decline as more

reports about the safety and efficacy of VYTORIN and defendants long-time knowledge of these

adverse conditions reached the market. As evidence of this as shares of Schearing Plough

continued to fall, the Associated Press reported, in part, the following:

Study: Cholesterol Combination Drug Vytorin Not Superior to Solo Drug

NEWARK, N.J. (AP) -- A clinical trial has shown that the combinationcholesterol drug Vytorin is no more effective than a high dose of one of itscomponents available generically, Vytorin's makers said Monday.

Vytorin, developed by Merck & Co. and Schering-Plough Corp., is a combinationof Zetia and Merck's Zocor, which lost patent protection in 2006. Amid concernsabout whether Vytorin posed a risk of liver damage, Wall Street has beenanxiously awaiting details on results of the study begun in 2002.

In the quarter ended Sept. 30, sales of Zetia and Vytorin hit $1.3 billion, up 26percent from the year-ago period.

The study measured the amount of artery-clogging plaque in three areas.

It focused on a group of 720 patients with a rare condition predisposing them tohigh cholesterol . The patients were given either Vytorin or a high dose of genericZocor, known as simvastatin.

In December, a congressional committee requested more information on thestudy. The results were delayed, the companies maintained, because of thecomplexity of the data. [Emphasis added.]

62. Again, on January 16, 2008, shares of the Company continued to decline as

reports that Congress was investigating Schering-Plough over its advertising, reached the market.

As evidence of this, that day the Associated Press further reported, in part, that:

Congress Investigating Vytorin Ads in Wake of Study

WASHINGTON (AP) -- Congress is investigating advertising for the cholesterol-busting drug Vytorin following a study that suggested the pill may have noadvantage over a generic cholesterol medicine , according to letters releasedWednesday.

In letters dated Wednesday and addressed to Schering-Plough Corp. and Merck

& Co., which jointly sell Vytorin, and the U.S. Food and Drug Administration,

Reps. John Dingell and Bart Stupak, Michigan Democrats, raised questions

about the adsfor the medicine.

In the letter to the companies, the congressmen wrote that the House ofRepresentatives ' Committee on Energy and Commerce and its Subcommittee onOversight and Investigations are probing the "withholding of clinical trial data

42

Page 43: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 43 of 63

that may significantly affect the medical management of hypercholesterolemia,as well as the use ofmisleading statement in direct-to-consumer advertisementsforprescription medicines.

Vytorin is in the news this week after the results of a long-awaited study, calledEnhance, indicated the drug may be no better than a generic statin at slowing theprogression of heart disease.

In the FDA letter, the lawmakers write that they are "concerned that the study'sresults may have been available to Schering-Plough and Merck officials, andyet the massive advertisement campaign for Vytorin was allowed to continue."They ask for agency records related to the Vytorin ads.

The congressmen also asked the companies for records related to the ads aswell materials related to Enhance study leader John Kastelein , a cardiologist inthe Netherlands. They also seek information about the press release this Mondaythat disclosed the Enhance results , almost two years after the last patientcompleted the study.

In 2005, the companies spent $155 million on Vytorin ads, a budget exceededthat year only by Sepracor Inc.'s Lunesta campaign and AstraZeneca PLC'sNexium ads, according to an article in the New England Journal of Medicine.[Emphasis added.]

63. Finally, on January 17, 2008, shares of the Company traded to just above $20.50

per share, as investors digested the news that defendants had purposefully delayed publishing the

report that demonstrated that VYTORIN was neither safe nor effective . That day, the

MotleyFool.com further reported, in part, the following:

2 Sources of Trouble for Vytorin

You know that a drug study has gone very, very bad when you can 'tfind out itsresults without a congressional inquiry.

Last month the House Committee on Energy and Commerce demandedinformation about the Enhance clinical trial. Some data was released on Jan. 14,and it's been a popular topic on television news since then.

Merck (NYSE: MRK) and Schering-Plough (NYSE: SGP) jointly market andshare the profits of Zetia and Vytorin. Zetia blocks the uptake of food-bornecholesterol from the digestive tract and thus lowers LDL (the lousy or lethal)cholesterol. Vytorin is a combination of Zetia and Zocor. Zocor is now availableas a generic, simvastatin.

43

Page 44: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 44 of 63

Simvastatin is a well-studied medication, and like other statins works on receptorsin the liver to lower cholesterol . Simvastatin and other brand-name statins , such asPfizer's (NYSE: PFE) Lipitor and AstraZeneca 's (NYSE: AZN) Crestor, lowercholesterol levels and lower the risk of heart attacks for many patients.

It is certainly well marketed. Surely you've heard the commercial: "There are twosources of cholesterol: food and family. Vytorin treats both. Sales of Zetia,approved in 2002, and Vytorin, approved in 2004, are around $5 billion annually,making it one of the world's best-selling drugs.

Although multiple studies prove that Zocor not only lowered cholesterol levelsbut also lowered the risk of heart attacks, there are no similar studies for Zetia orVytorin that demonstrate clinical benefits. If adding Zetia to Zocor (to makeVytorin) does not improve patients ' clinical outcomes more than just Zocor,then why take the more expensive medication?

The Enhance study was designed to show a benefit among patients takingVytorin, primarily by documenting less buildup of plaque in the carotid arteries, asurrogate for the progression of coronary artery disease.

In the trial, 720 patients with a genetic abnormality that caused extremely highlevels of LDL cholesterol were randomized into two groups. One receivedVytorin (Zocor plus Zetia), and the other group received Zocor. The Vytoringroup had a statistically lower level of LDL cholesterol, as expected; theincidence of serious side effects was low and similar in both groups. So far, sogood.

While not statistically significant, there was evidence of more thickening ofcarotid arteries in patients in the Vytorin group than in the Zocor group. TheVytorin group also had a minuscule, statistically non-significant, higher numberof deaths, heart attacks, and angioplasty or bypass surgeries. Although the numberof patients studied is small, and the type of patients studied is different from thoseusually prescribed the medication, the outcome trends went in the wrongdirection.

Dr. Robert Califf, noted Duke University cardiologist, stated that he plans tocontinue to take Zetia. "I don't see any signal of toxicity from this trial, so that isreassuring. There's no indication that it 's working, either, but that was also thecase before Enhance came out. For me, the fact it lowers LDL and does notappear to have side effects is enough until definitive outcome data becomeavailable.

Dr. Steven Nissen, Cleveland Clinic cardiologist -- of anti-GlaxoSmithKline's

(NYSE: GSK) Avandia fame -- expressed a different sentiment: "The main

problem is that after six years on the market, there are no data for ezetimibe

demonstrating any health outcome benefit. Statins do much more than lower

LDL. They increase HDL, lower triglycerides, and reduce inflammation. In the

absence of any demonstrable effect beyond LDL lowering, nearly 1 millionprescriptions per week are written for ezetimibe . Is this rational?

Adding salt to the wound, the biggest headache might comefrom Congress as itbegins to investigate why it took so long for the Enhance results to be madepublic. Congress is also investigating those ubiquitous Vytorin ads.

In an election year, hearings about who knew what details of the study, and when,can only be bad newsforprescription sales. [Emphasis added.]

64. The chart below, indicates the dramatic decline in the price of Company shares in

the short period between January 14 and January 17, 2008 , that followed the belated disclosures

regarding VYTORIN and ZETIA reaching the market, as follows:

CAUSATION AND ECONOMIC LOSS

65. During the Class Period, as detailed herein, defendants engaged in a scheme to

deceive the market, and a course of conduct that artificially inflated Schering-Plough's stock

price and operated as a fraud or deceit on Class Period purchasers of Schering-Plough's stock by

misrepresenting the status and results of the ENHANCE Study as well as the safety and efficacy

45

Page 46: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 46 of 63

of the Company' s leading drug products and, therefore, the Company' s financial results. Over a

period of approximately eighteen months, defendants improperly inflated the Company's

financial results . Ultimately, however, when defendants' prior misrepresentations and fraudulent

conduct came to be revealed and was apparent to investors, shares of Schering-Plough declined

precipitously - - evidence that the prior artificial inflation in the price of Schering-Plough's

shares was eradicated. As a result of their purchases of Schering-Plough stock during the Class

Period, plaintiff and other members of the Class suffered economic losses, i.e. damages under the

federal securities laws.

66. By improperly characterizing the status and results of the ENHANCE Study as

well as the safety and efficacy of the Company's leading drug products and, therefore, the

Company's financial results , costs and expenses, and misrepresenting its prospects, the

defendants presented a misleading image of Schering-Plough's business and future growth

prospects. During the Class Period, defendants repeatedly emphasized the safety and efficacy of

VYTORIN and ZETIA, and consistently reported costs and expenses within expectations and

within the range for which the Company was adequately reserved. These claims caused and

maintained the artificial inflation in Schering-Plough's stock price throughout the Class Period

and until the truth about the Company was ultimately revealed to investors.

67. Defendants' false and materially misleading statements had the intended effect of

causing Schering-Plough's shares to trade at artificially inflated levels throughout the Class

Period - - reaching a Class Period high of over $34.00 per share in late-May 2007.

68. On January 14 - 17, 2008, however, as investors learned the truth about the

Company, and learned that defendants had failed to report the results of the ENHANCE Study or

the impaired safety and efficacy of ZYTORIN, and once investors learned that Schering-Plough

was now being investigated by the Congress for its false advertising of its cholesterol drugs,

46

Page 47: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 47 of 63

shares of the Company declined precipitously. Defendants ' belated disclosures had an

immediate, adverse impact on the price of Schering-Plough shares.

69. These belated revelations also evidenced defendants' prior falsification of

Schering-Plough's business prospects due to defendants' false statements. As investors and the

market ultimately learned, the Company' s prior business prospects had been overstated as were

the Company's results of operations. As this adverse information became known to investors,

the prior artificial inflation began to be eliminated from Schering-Plough's share price and were

damaged as a result of the related share price decline.

70. As a direct result of investors learning the truth about the Company between

January 14 and 17, 2008 , Schering-Plough ' s stock price declined precipitously from just below

$28.00 per share, to a low of just over $22.50 per share - - representing a loss of market

capitalization of over decline of almost $8 billion, on very heavy trading volume. This dramatic

share price decline, eradicated much of the artificial inflation from Schering-Plough's share

price, causing real economic loss to investors who purchased this stock during the Class Period.

71. The decline in Schering-Plough ' s stock price at the end of the Class Period was a

direct result of the nature and extent of defendants' fraud being revealed to investors and to the

market. The timing and magnitude of Schering-Plough's stock price decline negates any

inference that the losses suffered by plaintiff and the other members of the Class was caused by

changed market conditions, macroeconomic or industry factors or even Company-specific facts

unrelated to defendants' fraudulent conduct.

72. The economic loss, i. e. damages suffered by plaintiff and other members of the

Class, was a direct result of defendants' fraudulent scheme to artificially inflate the price of

Schering-Plough's stock and the subsequent significant decline in the value of the Company's

VIOLATIONS OF GAAP AND SEC REPORTING RULES

73. During the Class period, defendants materially misled the investing public,

thereby inflating the price of the Company' s securities , by publicly issuing false and misleading

statements and omitting to disclose material facts necessary to make defendants' statements, as

set forth herein, not false and misleading. Said statements and omissions were materially false

and misleading in that they failed to disclose material adverse information and misrepresented

the truth about the Company, its financial performance, accounting, reporting, and financial

condition in violation of the federal securities laws and GAAP.

74. GAAP consists of those principles recognized by the accounting profession as the

conventions, rules, and procedures necessary to define accepted accounting practice at the

particular time. Regulation S-X, to which the Company is subject as a registrant under the

Exchange Act, 17 C.F.R. 210 .4-01(a)( 1), provides that financial statements filed with the SEC

48

Page 49: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 49 of 63

which are not prepared in compliance with GAAP, are presumed to be misleading and

inaccurate . SEC Rule 13a-13 requires issuers to file quarterly reports.

75. SEC Rule 12b-20 requires that periodic reports must contain such further

information as is necessary to make the required statements, in light of the circumstances

under which they are made, not misleading.

76. In addition, Item 303 of Regulation S-K requires that, for interim periods, the

Management Division and Analysis Section ("MD&A ) must include, among other things, a

discussion of any material changes in the registrant's results of operations with respect to the

most recent fiscal year-to-date period for which an income statement is provided. Instructions to

Item 303 require that the this discussion identify any significant elements of registrant's income

or loss from continuing operations that are not necessarily representative of the registrant's

ongoing business. Item 303(a)(2)(ii) to Regulation S-K requires the following discussion in the

MD&A of a company's publicly filed reports with the SEC:

Describe any known trends or uncertainties that have had or that the registrantreasonably expects will have a material favorable or unfavorable impact on netsales or revenues or income from continuing operations. If the registrant knows ofevents that will cause a material change in the relationship between costs andrevenues (such as known future increases in costs of labor or materials or priceincreases or inventory adjustments), the change in relationship shall be disclosed.

Paragraph 3 of the Instructions to Item 303 states in relevant part:

The discussion and analysis shall focus specifically on material events anduncertainties known to management that would cause reported financialinformation not to be necessarily indicative of future operating results or of futurefinancial condition. This would include descriptions and amounts of (A) mattersthat would have an impact on future operations and have not had an impact in thepast. .

77. The GAAP requirement for recognition of an adequate provision for foreseeable

costs and an associated allowance applies to interim financial statements as required by

49

Page 50: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Accounting Principles Board Opinion No. 28 . Paragraph 17 of this authoritative pronouncement

states that:

The amounts of certain costs and expenses are frequently subjected to year-endadjustments even though they can be reasonably approximated at interim dates.To the extent possible such adjustments should be estimated and the estimatedcosts and expenses assigned to interim periods so that the interim periods bear areasonable portion of the anticipated annual amount.

78. The Company' s financial statements contained in the fiscal 2006 Form 10-K

and/or the quarterly reports filed with the SEC on Forms 10-Q for the quarterly periods

throughout the Class Period were presented in a manner that violated the principle of fair

financial reporting and the following GAAP, among others:

(a) The principle that financial reporting should provide information that is

useful to present and potential investors and creditors and other users in making rational

investment, credit and similar decisions (FASB Statement of Concepts No. 1).

(b) The principle that financial reporting should provide information about an

enterprise's financial performance during a period (FASB Statement of Concepts No. 1).

(c) The principle that financial reporting should be reliable in that it

represents what it purports to represent (FASB Statement of Concepts No. 2).

(d) The principle of completeness, which means that nothing material is left

out of the information that may be necessary to ensure that it validly represents underlying

events and conditions (FASB Statement of Concepts No. 2).

(e) The principle that conservatism be used as a prudent reaction to

uncertainty to try to ensure that uncertainties and risks inherent in business situations are

adequately considered (FASB Statement of Concepts No. 2).

(f) The principle that contingencies and other uncertainties that affect the

fairness of presentation of financial data at an interim date shall be disclosed in interim reports in

the same manner required for annual reports (APB Opinion No. 28).

0) The principle that disclosures of contingencies shall be repeated in interim

and annual reports until the contingencies and have been removed, resolved, or have become

immaterial (APB Opinion No. 28).

(k) The principle that management should provide commentary relating to the

effects of significant events upon the interim financial results (APB Opinion No. 28).

79. In addition, during the Class Period, defendants violated SEC disclosure rules:

(a) defendants failed to disclose the existence of known trends, events or

uncertainties that they reasonably expected would have a material, unfavorable impact on net

revenues or income or that were reasonably likely to result in the Company's liquidity decreasing

in a material way, in violation of Item 303 of Regulation S-K under the federal securities laws

(17 C.F.R. 229. 303), and that failure to disclose the information rendered the statements that

were made during the Class Period materially false and misleading; and

(b) by failing to file financial statements with the SEC that conformed to the

requirements of GAAP, such financial statements were presumptively misleading and inaccurate

pursuant to Regulation S-X, 17 C.F.R. § 210.4-01(a)(1).

80. Defendants were required to disclose, in the Company's financial statements, the

existence of the material facts described herein and to appropriately recognize and report assets,

revenues , and expenses in conformity with GAAP. The Company failed to make such

disclosures and to account for and to report its financial statements in conformity with GAAP.

Defendants knew, or were reckless in not knowing, the facts which indicated that the fiscal 2006

51

Page 52: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 52 of 63

Form 10-K and all of the Company's interim financial statements , press releases , public

statements, and filings with the SEC, which were disseminated to the investing public during the

Class Period, were materially false and misleading for the reasons set forth herein. Had the true

financial position and results of operations of the Company been disclosed during the Class

period, the Company's common stock would have traded at prices well below that which it did.

ADDITIONAL SCIENTER ALLEGATIONS

81. As alleged herein, defendants acted with scienter in that each defendant knew that

the public documents and statements issued or disseminated in the name of the Company were

materially false and misleading; knew that such statements or documents would be issued or

disseminated to the investing public; and knowingly and substantially participated or acquiesced

in the issuance or dissemination of such statements or documents as primary violations of the

federal securities laws. As set forth elsewhere herein in detail, defendants, by virtue of their

receipt of information reflecting the true facts regarding Schering-Plough, their control over,

and/or receipt and/or modification of Schering-Plough's allegedly materially misleading

misstatements and/or their associations with the Company which made them privy to

confidential proprietary information concerning Schering-Plough, participated in the fraudulent

scheme alleged herein.

82. Defendants were motivated to materially misrepresent to the SEC and investors

the true financial condition of the Company because : (i) deceive the investing public regarding

Schering-Plough's business, operations, management and the intrinsic value of Schering-Plough

common stock; (ii) enable defendants to artificially inflate the price of Schering-Plough shares;

(iii) enabled Schering-Plough insiders to sell almost $45 million of their privately held Schering-

Plough shares and it allowed the Company itself to register and sell over $1. 6 billion in newly

issued common stock during the Class Period and while in possession of material adverse non-

52

Page 53: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

public information about the Company; and (iv) cause plaintiff and other members of the Class

to purchase Schering-Plough common stock at artificially inflated prices. In furtherance of this

unlawful scheme, plan and course of conduct, defendants, jointly and individually (and each of

them) took the actions set forth herein.

83. As further evidence of defendants' scienter, during the Class Period, while in

possession of material adverse non-public information about the Company, the senior-most

officers of Schering Plough liquidated large amounts of their privately held Company stock

while in possession of material adverse information about VYTORIN and ZETIA. These sales

were unusual in their timing and amount, and are evidenced by the chart below, as follows:

84. At all relevant times, the market for Schering-Plough's common stock was an

efficient market for the following reasons, among others:

(a) Schering-Plough's stock met the requirements for listing, and was listed

and actively traded on the NYSE national market exchange, a highly efficient and automated

market;

54

Page 55: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 55 of 63

(b) As a regulated issuer, Schering-Plough filed periodic public reports with

the SEC and the NYSE;

(c) Schering-Plough regularly communicated with public investors via

established market communication mechanisms, including through regular disseminations of

press releases on the national circuits of major newswire services and through other wide-

ranging public disclosures , such as communications with the financial press and other similar

reporting services; and

(d) Schering-Plough was followed by several securities analysts employed by

major brokerage firm(s) who wrote reports which were distributed to the sales force and certain

customers of their respective brokerage firm(s). Each of these reports was publicly available and

entered the public marketplace.

85. As a result of the foregoing, the market for Schering-Plough securities promptly

digested current information regarding Schering-Plough from all publicly available sources and

reflected such information in Schering-Plough stock price. Under these circumstances, all

purchasers of Schering-Plough common stock during the Class Period suffered similar injury

through their purchase of Schering-Plough common stock at artificially inflated prices and a

presumption of reliance applies.

NO SAFE HARBOR

86. The statutory safe harbor provided for forward-looking statements under certain

circumstances does not apply to any of the allegedly false statements pleaded in this complaint.

Many of the specific statements pleaded herein were not identified as "forward-looking

statements when made. To the extent there were any forward-looking statements, there were no

meaningful cautionary statements identifying important factors that could cause actual results to

differ materially from those in the purportedly forward-looking statements . Alternatively, to the

55

Page 56: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 56 of 63

extent that the statutory safe harbor does apply to any forward-looking statements pleaded

herein, defendants are liable for those false forward-looking statements because at the time each

of those forward-looking statements was made, the particular speaker knew that the particular

forward-looking statement was false, and/or the forward-looking statement was authorized

and/or approved by an executive officer of Schering-Plough who knew that those statements

were false when made.

BASIS OF ALLEGATIONS

87. Plaintiff has alleged the following based upon the investigation of plaintiff's

counsel, which included a review of SEC filings by Schering-Plough, as well as regulatory

filings and reports, securities analysts' reports and advisories about the Company, press releases

and other public statements issued by the Company, and media reports about the Company, and

plaintiff believes that substantial additional evidentiary support will exist for the allegations set

forth herein after a reasonable opportunity for discovery.

FIRST CLAIM

Violation Of Section 10(b) OfThe Exchange Act And Rule 10b-5

Promulgated Thereunder Against All Defendants

88. Plaintiff repeats and realleges each and every allegation contained above as if

fully set forth herein.

89. During the Class Period, defendants carried out a plan, scheme and course of

conduct which was intended to and, throughout the Class Period, did: (i) deceive the investing

public regarding Schering-Plough's business, operations, management and the intrinsic value of

Schering-Plough common stock; (ii) enable defendants to artificially inflate the price of

Schering-Plough shares; (iii) enabled Schering-Plough insiders to sell almost $45 million of their

privately held Schering-Plough shares and it allowed the Company itself to register and sell over

56

Page 57: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 57 of 63

$1.6 billion in newly issued common stock during the Class Period and while in possession of

material adverse non-public information about the Company; and (iv) cause plaintiff and other

members of the Class to purchase Schering-Plough common stock at artificially inflated prices.

In furtherance of this unlawful scheme, plan and course of conduct, defendants, jointly and

individually (and each of them) took the actions set forth herein.

90. Defendants (a) employed devices, schemes, and artifices to defraud; (b) made

untrue statements of material fact and/or omitted to state material facts necessary to make the

statements not misleading; and (c) engaged in acts, practices, and a course of business which

operated as a fraud and deceit upon the purchasers of the Company's common stock in an effort

to maintain artificially high market prices for Schering-Plough's common stock in violation of

Section 10(b) of the Exchange Act and Rule lOb-5. All defendants are sued either as primary

participants in the wrongful and illegal conduct charged herein or as controlling persons as

alleged below.

91. Defendants, individually and in concert, directly and indirectly, by the use, means

or instrumentalities of interstate commerce and/or of the mails, engaged and participated in a

continuous course of conduct to conceal adverse material information about the business,

operations and future prospects of Schering-Plough as specified herein.

92. These defendants employed devices, schemes and artifices to defraud, while in

possession of material adverse non-public information and engaged in acts, practices, and a

course of conduct as alleged herein in an effort to assure investors of Schering-Plough's value

and performance and continued substantial growth, which included the making of, or the

participation in the making of, untrue statements of material facts and omitting to state material

facts necessary in order to make the statements made about Schering-Plough and its business

operations and future prospects in the light of the circumstances under which they were made,

57

Page 58: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 58 of 63

not misleading, as set forth more particularly herein, and engaged in transactions, practices and a

course of business which operated as a fraud and deceit upon the purchasers of Schering-Plough

common stock during the Class Period.

93. Each of the Individual Defendants' primary liability, and controlling person

liability, arises from the following facts: (i) the Individual Defendants were high-level executives

and/or directors at the Company during the Class Period and members of the Company's

management team or had control thereof; (ii) each of these defendants, by virtue of his

responsibilities and activities as a senior officer and/or director of the Company was privy to and

participated in the creation, development and reporting of the Company's internal budgets, plans,

projections and/or reports; (iii) each of these defendants enjoyed significant personal contact and

familiarity with the other defendants and was advised of and had access to other members of the

Company's management team, internal reports and other data and information about the

Company's finances, operations, and sales at all relevant times ; and (iv) each of these defendants

was aware of the Company's dissemination of information to the investing public which they

knew or recklessly disregarded was materially false and misleading.

94. The defendants had actual knowledge of the misrepresentations and omissions of

material facts set forth herein, or acted with reckless disregard for the truth in that they failed to

ascertain and to disclose such facts. Such defendants' material misrepresentations and/or

omissions were done knowingly or with recklessly for the purpose and effect of concealing

Schering-Plough's operating condition and future business prospects from the investing public

and supporting the artificially inflated price of its common stock. As demonstrated by

defendants' overstatements and misstatements of the Company' s business , operations and

earnings throughout the Class Period, defendants, if they did not have actual knowledge of the

misrepresentations and omissions alleged, were reckless in failing to obtain such knowledge by

58

Page 59: Case2:08-cv-00397-DMC-MF Document1 Filed 01/18/2008 Page 1 …securities.stanford.edu/filings-documents/1039/SGP_01/... · 2008. 3. 16. · Case2:08-cv-00397-DMC-MF Document1 Filed

Case 2:08-cv-00397-DMC-MF Document 1 Filed 01/18/2008 Page 59 of 63

recklessly refraining from taking those steps necessary to discover whether those statements

were false or misleading.

95. As a result of the dissemination of the materially false and misleading information

and failure to disclose material facts, as set forth above, the market price of Schering-Plough

common stock was artificially inflated during the Class Period. In ignorance of the fact that

market prices of Schering-Plough's publicly-traded common stock were artificially inflated, and

relying directly or indirectly on the false and misleading statements made by defendants, or upon

the integrity of the market in which the securities trade, and/or on the absence of material

adverse information that was known to or recklessly disregarded by defendants but not disclosed

in public statements by defendants during the Class Period, plaintiff and the other members of

the Class acquired Schering-Plough common stock during the Class Period at artificially high

prices and were damaged thereby.

96. At the time of said misrepresentations and omissions , plaintiff and other members

of the Class were ignorant of their falsity, and believed them to be true. Had plaintiff and the

other members of the Class and the marketplace known the truth regarding the problems that

Schering-Plough was experiencing, which were not disclosed by defendants, plaintiff and other

members of the Class would not have purchased or otherwise acquired their Schering-Plough

common stock, or, if they had acquired such common stock during the Class Period, they would

not have done so at the artificially inflated prices which they paid.

97. By virtue of the foregoing, defendants have violated Section 10(b) of the

Exchange Act, and Rule IOb-5 promulgated thereunder.

98. As a direct and proximate result of defendants' wrongful conduct, plaintiff and

the other members of the Class suffered damages in connection with their respective purchases

and sales of the Company's common stock during the Class Period.

SECOND CLAIM

Violation Of Section 20(a) OfThe Exchange Act Against Individual Defendants

99. Plaintiff repeats and realleges each and every allegation contained above as if

fully set forth herein.

100. The Individual Defendants acted as controlling persons of Schering-Plough within

the meaning of Section 20(a) of the Exchange Act as alleged herein. By virtue of their high-level

positions, and their ownership and contractual rights, participation in and/or awareness of the

Company's operations and/or intimate knowledge of the false financial statements filed by the

Company with the SEC and disseminated to the investing public, the Individual Defendants had

the power to influence and control and did influence and control, directly or indirectly, the

decision-making of the Company, including the content and dissemination of the various

statements which plaintiff contends are false and misleading . The Individual Defendants were

provided with or had unlimited access to copies of the Company's reports, press releases , public

filings and other statements alleged by plaintiff to be misleading prior to and/or shortly after

these statements were issued and had the ability to prevent the issuance of the statements or

cause the statements to be corrected.

101. In particular, each of these defendants had direct and supervisory involvement in

the day-to-day operations of the Company and, therefore, is presumed to have had the power to

control or influence the particular transactions giving rise to the securities violations as alleged
