FOR THE NORTHERN DISTRICT OF TEXAS

  TENET HEALTHCARE CORPORATION,   Plaintiff,   v.   COMMUNITY HEALTH SYSTEMS, INC., WAYNE T. SMITH, and W. LARRY CASH,   Defendants. x : : : : : : : : : : : x Civ. No. 3:11-cv-00732-M

BRIEF IN SUPPORT OF PLAINTIFF’S MOTION FOR EXPEDITED

DISCOVERY

By this motion, Plaintiff Tenet Healthcare Corporation (Tenet) urges this Court to grant expedited discovery. Tenet seeks tailored discovery to develop a more complete factual record in advance of a preliminary injunction hearing demonstrating Community Health Systems, Inc. (CHS) has inadequately disclosed its billing practices, including its pervasive practice of billing Medicare for inpatient admissions when those admissions were medically unnecessary and when outpatient observation would have been appropriate. In doing so, CHS has inflated its bills to Medicare, and thus has inflated the company’s revenues and profits.

Since Tenet’s lawsuit came to light on April 11, various federal and state government investigations, qui tam lawsuits, and a key analysis by a CHS shareholder have emerged. All of these investigations and the shareholder analysis predate Tenet’s

Complaint and make similar allegations. Yet CHS had disclosed only one — an investigation by the Texas Attorney General of CHS’s hospitals in Texas — as of the filing of Tenet’s Complaint. And CHS disclosed Texas’s investigation more than three months after the company was served with Civil Investigative Demands. Tenet seeks targeted and expedited discovery of these and related matters, in the form of discovery attached to this motion, to provide its shareholders with a complete and fair picture of CHS, Tenet’s would-be acquirer, in time for shareholders to decide whether to elect CHS-sponsored directors or Tenet’s nominees at a November 3, 2011 Tenet annual meeting.

This case stems from a series of materially false and misleading proxy solicitation statements made by CHS, its Chief Executive Officer Wayne T. Smith, and its Chief Financial Officer W. Larry Cash in an attempt to convince Tenet’s shareholders to replace the current members of Tenet’s Board of Directors with CHS-backed nominees at Tenet’s shareholder meeting in November. To prevent irreparable harm to Tenet and its shareholders, Tenet seeks a preliminary injunction requiring accurate and complete disclosures by CHS before the November shareholder meeting so Tenet shareholders may make informed judgments about the future governance of their company.

As various courts, including courts in the Fifth Circuit, have held, expedited discovery is warranted in circumstances where a plaintiff seeks interim injunctive relief and where the discovery requests are targeted at information critical to the expedited

2

proceedings. For these reasons, Tenet respectfully requests this Court grant expedited discovery.¹

BACKGROUND AND STATEMENT OF FACTS

As Tenet details in its Complaint, CHS employs a business model that is premised on admitting patients, primarily from the emergency room, into its hospitals based on medically inappropriate admission criteria reflected in a home-grown CHS document it calls the Blue Book, rather than treating these patients in observation status, as it should. This practice results in substantially higher and unwarranted billings to Medicare and other payors. Defendants’ growth strategy for over a decade has been to acquire hospitals and boost their financial performance by employing CHS’s Blue Book admissions criteria. A leading example of this strategy is CHS’s 2007 acquisition of Plano-based Triad Hospitals, Inc. Within one year of the acquisition, CHS cut in half the use of observation status at the former Triad hospitals.

Defendants’ latest gambit is a bid to acquire Tenet. On November 12, 2010, CHS made an unsolicited offer to acquire all outstanding shares of Tenet stock for $6.00 per share ($5.00 in cash and $1.00 in CHS stock). After Tenet’s Board of Directors unanimously rejected the CHS offer, CHS announced that it planned to nominate a slate of directors to replace Tenet’s existing board at Tenet’s next annual shareholder meeting, which is scheduled for November 3, 2011.

¹  The proposed discovery requests are attached as Exhibit A.

3

On April 11 of this year, and after painstaking study, Tenet filed this lawsuit to compel CHS to correct misstatements made by CHS and its management about CHS’s business practices — statements designed to convince Tenet’s shareholders to elect the CHS slate. Tenet further alleges that Defendants’ misrepresentations and omissions have disguised CHS’s financial exposure to the federal government for false claims to Medicare, as well as its exposure to states, private insurers, and other payors — significant liabilities impairing CHS’s ability to finance a potential acquisition of Tenet.

Defendants promptly responded to the filing of the lawsuit with a press release proclaiming the allegations “baseless” and “completely without merit” and protesting that “CHS conducts its business with the utmost integrity and adheres to the highest business practice standards.” In the days following, though, CHS issued a series of remarkable disclosures that support the merits of Tenet’s lawsuit and that highlight the critical importance of requiring CHS to speak truthfully to Tenet’s shareholders.

After several days of private conversations and meetings with financial analysts, media, and selected shareholders to cast doubt on Tenet’s allegations, and after the markets had closed for the week, on Friday afternoon, April 15, CHS disclosed that it had received a subpoena dated March 31, 2011 — eleven days before Tenet’s lawsuit — from the Department of Health and Human Services (HHS) Office of Inspector General (OIG). CHS claimed to have received the filing on April 8, still three days before Tenet filed its Complaint. According to CHS, the subpoena was issued “in connection with an investigation of possible improper claims submitted to Medicare and Medicaid … and … requests documents from all of our hospitals and appears to concern emergency

4

department processes and procedures.” CHS’s belated disclosure went on to state that “[t]he subpoena’s requests are very similar to those contained in the Civil Investigative Demands received by our Texas hospitals from the Office of the Attorney General of the State of Texas on November 15, 2010.”² Finally, CHS professed not to know if the subpoena was related to the allegations in Tenet’s lawsuit. Investors evidently considered the Friday afternoon disclosure to be material; when the markets opened the following Monday morning, CHS’s stock was down more than 14% from the closing price the previous Friday.

On Monday April 18, CHS made yet another belated disclosure. Apparently, more than six months earlier CHS had received a letter from a pension fund shareholder group detailing CHS’s “higher than expected admissions from the emergency room at CHS hospitals” and high level of short stay admissions — clear signals that CHS hospitals were overbilling Medicare by admitting patients who should have been treated in observation status. Thus, at the time that Defendants were dismissing Tenet’s allegations as meritless, CHS knew full well that federal regulators were investigating and that an institutional shareholder was questioning the very same business practices

²  CHS’s disclosure of the Texas CIDs, issued more than three months after they were served on the company, was vague, saying only that the CIDs concerned “emergency department procedures and billing.”

5

challenged in Tenet’s lawsuit.³

On April 22, one week later, CHS issued yet another late-Friday disclosure. In it CHS described a False Claims Act qui tam lawsuit that had been filed in January 2009 by a former employee at an Indiana hospital that was among the Triad hospitals acquired by CHS in 2007. CHS further revealed that the United States Department of Justice was now “considering this suit in light of the investigation that is the subject of” the April 8, 2011 subpoena. Inexplicably, CHS failed to disclose that the qui tam lawsuit alleges that CHS’s false claims have resulted from improper emergency room admission practices and that CHS had been aware of the investigation as early as 2009.

Indeed, the sworn qui tam complaint, filed by a registered nurse who worked at Lutheran Hospital in Fort Wayne, Indiana for twenty-three years, contains the same allegations that Tenet makes here. See Exhibit B. The nurse alleges under oath that after CHS acquired Lutheran Hospital as part of the Triad acquisition, CHS required Lutheran Hospital to use CHS’s Blue Book, which contained “exceptionally simplistic and nonspecific” admissions criteria to drive up admissions and drive down observations, thereby reaping substantially higher reimbursement from Medicare. Id. at 19. The complaint further alleges that the purported “synergies” CHS “realized” through the Triad acquisition were based on improper admissions practices, including that “CHS

³  It appears that the April 18 disclosure was only as a result of a second letter from the same shareholder group, dated April 15, 2011, which noted that it had never received a substantive reply to its previous letter and that its concerns were now heightened by Tenet’s lawsuit.

6

began changing the case management of short stay cases, educating physicians and Case Managers to use ‘inpatient’ status rather than ‘23 hour observation’ in direct opposition to the training given to physician’s [sic] in earlier years. CHS justified this by the use of questionable medical criteria they devised and different than that established by Medicare, i.e. Blue Book vs InterQual criteria.” Id. at 24. The qui tam complaint further alleges that CHS management informed the hospital’s case managers that CHS focused intensely on case management and that all hospital personnel were required to be educated on how to employ Blue Book criteria.

The next shoe dropped on Monday April 25, when CHS revealed that the United States and the relator had filed a joint motion to stay the Indiana qui tam case to allow the government additional time to consider intervention. The joint motion revealed for the first time that other qui tam actions were pending against CHS in other jurisdictions, that the Department of Justice, multiple United States Attorneys’ offices, and the HHS OIG were coordinating their nationwide investigation of CHS and its related entities, and that these regulators were cooperating with the Attorney General of Texas and other states in investigating the allegations. Finally, erasing any uncertainty raised by CHS in its April 15 disclosure, the United States made clear in its motion that Tenet’s allegations in this lawsuit are related to this nationwide investigation.

Because of intense scrutiny of its wrongful business practices, CHS has now taken a number of obvious steps to avoid the disclosures that Tenet’s allegations would mandate and to attempt to squelch Tenet’s investigation of CHS altogether. On Monday, April 18, CHS announced that it had changed the terms of its offer to acquire Tenet from

7

$5.00 cash and $1.00 of CHS stock to an all-cash $6.00 offer. The reason CHS offered the maneuver was simple — to try to avoid Tenet’s claims and the difficult disclosures that would ensue. As Defendant Wayne Smith noted in the CHS press release, converting to an all-cash offer was an effort to render Tenet’s lawsuit “irrelevant to our offer.”⁴

Then, on April 21, 2011, Tenet’s counsel received a letter from Defendants’ counsel that attempts to chill discovery of further information about Defendants’ conduct. See Exhibits C, D. In the letter, Defendants’ counsel warned that former employees of CHS and Triad “may seek to peddle purported information about CHS or Triad” and that “serious legal consequences,” including the striking of pleadings, sanctions and claims for money damages, could result from the use of information provided by these “scofflaws.” Exhibit C at 1-2.

Defendants’ efforts to squelch Tenet’s legitimate discovery efforts is predictable in

⁴  Contrary to Defendants’ assertion, the all-cash proposal changes nothing in this litigation. Defendants’ cannot avoid their disclosure problems by converting to an all-cash proposal because the federal securities laws still require CHS and its management to communicate truthful and accurate information to Tenet’s shareholders about, among other things, CHS’s business practices, which are highly material to CHS’s ability to raise financing to consummate the transaction. See Rondeau v. Mosinee Paper Corp., 422 U.S. 49, 58-59 (1975) (“The purpose of the Williams Act is to insure that public shareholders who are confronted by a cash tender offer for their stock will not be required to respond without adequate information regarding the qualifications and intentions of the offering party” (emphasis added)). More generally, no matter the type of consideration being offered, the federal securities laws require that CHS tell the truth to Tenet’s shareholders as they make the fundamental decision about whether to elect the slate of directors, who were nominated by CHS to further its ambition of acquiring Tenet.

8

light of the revelations in the few weeks since this lawsuit was filed. It is more clear than ever, however, that discovery is imperative so that this Court, in advance of the November shareholder meeting, will have all the facts necessary to determine what additional disclosures are necessary for the shareholders to be in a position to properly consider the election of CHS-sponsored directors.

ARGUMENT

I. TENET IS ENTITLED TO EXPEDITED DISCOVERY IN CONNECTION WITH ITS PLANNED APPLICATION FOR A PRELIMINARY INJUNCTION

A. Good Cause Exists To Grant Expedited Discovery In Preliminary Injunction Cases Like This One

Tenet seeks expedited discovery to develop the record and assist this Court’s consideration of the key issues that will be raised in a preliminary injunction hearing. This discovery is particularly appropriate where, as here, there is an imminent danger of a corporate takeover based on false and misleading information. This Court has broad discretion to “expedite the discovery process through a scheduling order.” Barrett v. Atlantic Richfield Co., 95 F.3d 375, 380 (5th Cir. 1996); see also Fed. R. Civ. P. 16(b), 26(d)(1). Indeed, the Federal Rules specifically allow discovery “before the time specified in Rule 26(d).” Fed. R. Civ. P. 30(a)(2)(A)(iii); see also Fed. R. Civ. P. 31(a), 33(b), 34(b), 36(a), 45; accord, e.g., Advanced Portfolio Techs., Inc. v. Advanced Portfolio Techs., Ltd., 1994 WL 719696, at *3 (S.D.N.Y. Dec. 28, 1994) (“[E]xpedited deposition discovery is made available by Rule 30(a) of the Federal Rules of Civil Procedure.”).

9

Expedited discovery is appropriate where “there is some showing of good cause to justify the order” — including in cases “seeking a preliminary injunction.” Rodale, Inc. v. U.S. Preventive Med., Inc., 2008 WL 4682043, at *1 (E.D. Tex. Oct. 21, 2008); see also Tracfone Wireless, Inc. v. King Trading, Inc., 2008 WL 918243, at *1 (N.D. Tex. Mar. 13, 2008) (Kaplan, M.J.) (granting “expedited discovery . . . to enable plaintiff to determine the nature and extent of defendants’ alleged [wrongful acts] so it can decide whether to seek preliminary injunctive relief” (emphasis added)). In fact, courts routinely grant expedited discovery where a party seeks preliminary injunctive relief. See, e.g., King Aero. Commercial Corp. v. Al-Anwa Aviation, Inc., 2009 WL 804122, at *7 (N.D. Tex. Mar. 25, 2009) (Lindsay, J.).⁵ In particular, there is good cause for expedited discovery in corporate control contests such as this one because prompt disclosure of accurate information is critical. See Mesa Petroleum Co. v. Aztec Oil & Gas Co., 406 F. Supp. 910, 917 (N.D. Tex. 1976) (Higginbotham, J.) (ordering expedited discovery in corporate control contest); City P’ship Co. v. Atl. Acquisition Ltd. P’ship, 100 F.3d 1041, 1043 (1st Cir. 1996) (affirming district court, which also ordered expedited discovery in corporate control contest). Expedited discovery is “quite conventional in litigation of this type” because “[c]ases involving contests for corporate control are of necessity very fast-

⁵  See also, e.g., Providence Prop. & Cas. Ins. Co. v. PeopLease Corp., 2007 WL 2241492, at *2 (E.D. Tex. Aug. 3, 2007); Anderson v. Orleans Parish Sch. Bd., 2004 WL 1373269, at *5 (E.D. La. June 16, 2004); Ellsworth Assocs. v. United States, 917 F. Supp. 841, 844 (D.D.C. 1996) (“[E]xpedited discovery is particularly appropriate when a plaintiff seeks injunctive relief because of the expedited nature of injunctive proceedings.”).

10

moving.” Am. Stores Co. v. Lucky Stores, Inc., 1988 WL 909330, at *2 (Del. Ch. Apr. 13, 1988).

As we explain more fully below, there can be no question that there is good cause for expedited discovery in this case given CHS’s pattern of belated and deficient disclosure, the urgency of completing discovery in advance of an imminent preliminary injunction hearing, and the complexity of factual issues to be discovered in this case.

B. The PSLRA, Which Was Passed To Combat Strike Suits, Does Not Prevent Expedited Discovery In This Corporate Control Contest

Nor does the PSLRA, 15 U.S.C. § 78u-4(b)(3)(B), alter Tenet’s right to expedited discovery in this corporate control contest. Congress enacted the PSLRA to combat strike suits brought by private securities plaintiffs who, Congress concluded, had been using the federal securities laws to hold corporations hostage by filing baseless lawsuits and using the threat of burdensome and expensive discovery as a stick to obtain quick settlements. To combat this abusive tactic, the PSLRA contains a provision that stays discovery in such suits brought under the federal securities laws until after the decision on a motion to dismiss. In their Response to Plaintiff’s Motion for Rule 16 Scheduling Conference (“Rule 16 Response”), Defendants assert that the PSLRA should apply outside the strike suit arena to prevent discovery in a context that was never contemplated by Congress when it passed the PSLRA — a high stakes corporate control contest between two corporations.

Indeed, the PSLRA even carves out an exception to the discovery stay for the precise circumstances presented here: where expedited discovery is essential to the

11

plaintiff obtaining the relief it seeks. Specifically, the PSLRA makes clear that discovery may proceed when “particularized discovery is necessary . . . to prevent undue prejudice to [a] party.” Id. (emphasis added); see also, e.g., In re Royal Ahold N. V. Sec. & ERISA Litig., 319 F. Supp. 2d 634, 635 (D. Md. 2004) (lifting stay where “delay in the . . . particularized discovery sought here would cause undue prejudice to [plaintiffs’] ability to litigate and, most significantly, resolve as expeditiously as possible their claims”). Importantly, courts define “undue prejudice” as mere “improper or unfair treatment”—i.e., “something less than irreparable harm.” Vacold LLC v. Cerami, 2001 WL 167704, at *6 (S.D.N.Y. Feb. 16, 2001) (emphasis added); see also In re Countrywide Fin. Corp. Derivative Litig. (“Countrywide”), 542 F. Supp. 2d 1160, 1181 n.30 (C.D. Cal. 2008) (noting that the “undue prejudice” showing “need not reach the level of irreparable harm”); Med. Imaging Ctrs. of Am., Inc. v. Lichtenstein, 917 F. Supp. 717, 721 (S.D. Cal. 1996) (describing the lower “undue prejudice” burden as Congress’ attempt “to balance the competing concerns of maintaining truth and integrity in the marketplace while curbing meritless litigation”).

Here, there can be no question that Tenet and its shareholders will suffer undue harm absent the ability to immediately proceed with the focused discovery it seeks in support of a preliminary injunction. Many of the core facts that CHS has failed to disclose, as well as the circumstances behind its belated and insufficient recent disclosures, are uniquely within CHS’s control. Tenet has carefully crafted narrow discovery requests intended to target the specific documents it will need at the preliminary injunction hearing. Expedited and particularized written discovery is

12

essential so that there will be time (1) to promptly resolve objections Defendants inevitably will assert, (2) for Defendants to collect and produce the documents and respond to the interrogatories, and (3) for Plaintiff to review the document production and interrogatory answers, all in advance of depositions that must be taken in advance of a preliminary injunction hearing. And, critically, to give Tenet shareholders sufficient time to consider the corrective disclosures that would be required of CHS after a successful preliminary injunction, a preliminary injunction hearing must be set well in advance of the November 3 meeting, placing even more pressure on the discovery schedule. If this Court stays discovery pending its decision on the motion to dismiss, it will be virtually impossible for the discovery necessary for the preliminary injunction hearing and the resulting hearing itself to be completed before the November shareholder meeting, eliminating the ability of this Court to provide a proper remedy to the benefit of Tenet’s shareholders and causing undue prejudice to Plaintiff. See In re Fannie Mae Secs. Litig., 362 F. Supp. 2d 37, 39 (D.D.C. 2005) (defining undue prejudice as, in part, a defendant being “unfairly shielded from liability” if the necessary discovery is stayed).

In Defendants’ Rule 16 Response, Defendants tacitly concede that if delayed now, discovery will not be completed in time for a preliminary injunction hearing when they suggest that post-election remedies would be available after the November 3 meeting. Rule 16 Resp. at 4. Unscrambling the egg after a new slate of directors has been elected to a company would be impossible. Indeed, as the Supreme Court has noted, “in corporate control contests the stage of preliminary injunctive relief, rather than post-contest lawsuits, is the time when relief can best be given.” Piper v. Chris-Craft Indus.,

13

Inc., 430 U.S. 1, 41-42 (1977) (internal citations omitted).

Thus, the undue prejudice that would befall Tenet if it were unable to proceed with expedited discovery does not merely result from a delay in Tenet’s ability to obtain discovery, as Defendants misleadingly suggest in their Rule 16 Response. Instead, the undue prejudice against Tenet would result from its inability to ever obtain the relief it seeks, since, absent expedited discovery, it would be virtually impossible to reach a fully-informed decision on Tenet’s preliminary injunction sufficiently in advance of the November meeting to allow Tenet’s shareholders to appropriately consider CHS’s corrective disclosures that followed from that hearing. When such immediate action is needed, courts have allowed discovery to proceed under the PSLRA exception. Global Intellicom, Inc. v. Thompson Kernaghan & Co., 1999 WL 223158, at *2 (S.D.N.Y. Apr. 16, 1999) (lifting stay where there was a threat that defendants were “seeking to take over the company”); In re Websecure, Inc. Sec. Litig., 1997 WL 770414, at *4 (D. Mass. Nov. 26, 1997) (lifting stay and granting expedited discovery in connection with possible preliminary injunction).⁶

Just as in these cases, expedited discovery is necessary here given that Tenet seeks

⁶  In their Rule 16 Response, Defendants cite two cases in which courts found plaintiffs did not meet the test laid out in the text of the statute. See, e.g., Countrywide, 542 F. Supp. 2d at 1180 (refusing to lift stay only because plaintiffs’ discovery requests were not sufficiently particularized, and explicitly granting plaintiffs leave to refile their motion for expedited discovery); Lichtenstein, 917 F. Supp. at 722 (refusing to lift stay because relief would still be available after proxy contest decided). But those cases are inapposite, since in this case, Plaintiff plainly falls within the statutory exception: it is critical that discovery not wait.

14

to redress Defendants’ dissemination of false and misleading information. The key documents concerning CHS’s widespread and improper admissions criteria are in Defendants’ possession. Without access to this information, Tenet will be unable to present the Court a complete record demonstrating the necessity of enjoining Defendants’ continuing failure to make full and accurate disclosures. Although Tenet has gathered some evidence demonstrating the existence of misconduct by Defendants, Tenet cannot, in sufficient time for the preliminary injunction hearing, unearth the extent of Defendants’ misstatements and omissions without expedited discovery.

C. Tenet’s Narrow Discovery Requests Further Support Expedited Discovery

Expedited discovery is particularly appropriate in this case because Tenet’s discovery requests are carefully targeted to the information required at this stage of the proceeding. For example, Tenet seeks expedited discovery of documents concerning the training of doctors and case managers on the use of the Blue Book; communications with hospital executives about the Blue Book and other admissions-related matters such as the monitoring of physician admissions; documents concerning admission targets or goals at the hospitals and incentives to meet those goals; documents concerning the use of observation status at CHS hospitals; and documents related to CHS’s awareness of and production of documents in connection with the other ongoing investigations of related allegations.

Thus, the expedited discovery in this matter would be directed to ascertaining facts bearing directly on whether and to what extent Defendants’ solicitations and public

15

statements about matters such as the integrity of CHS’s business practices, CHS’s ability to realize “synergies” from an acquisition of Tenet and CHS’s potential legal exposure to the government and others contain material misstatements and omissions — in other words, information relevant to ensuring Tenet’s shareholders are fully informed before they consider CHS’s slate of directors. This information goes to the heart of CHS’s allegedly false and misleading statements to Tenet’s shareholders, and therefore serves as necessary and appropriate subject matter for discovery in anticipation of a preliminary injunction hearing. See, e.g., Arista Records LLC v. Does 1-9, 2007 WL 1059049, at *1 (D. Colo. Apr. 4, 2007) (finding good cause where “[p]laintiffs have proposed narrowly tailored discovery”).

Each of these sources of information will greatly aid the Court in determining the extent of Defendants’ false statements and omissions as well as determining how the misstatements can be corrected so that Tenet’s shareholders can make a fully informed decision in November. To have any meaningful effect, these determinations must be made on an expedited basis — and in any event well in advance of the November meeting of Tenet’s shareholders — “to allow a time for clearing the air and disseminating the information necessary to eradicate false impressions.” Edelman v. Salomon, 559 F. Supp. 1178, 1189 (D. Del. 1983) (granting preliminary injunction on a Section 14(a) claim).

Tenet and its shareholders will suffer undue prejudice if a full and complete record cannot be presented to the Court at a preliminary injunction hearing held in advance of the shareholder meeting. Time is of the essence, and the Court therefore should lift the

16

PSLRA stay and allow expedited and targeted discovery to proceed even while the Court considers the motion to dismiss.

CONCLUSION

Tenet respectfully requests that this Court grant the expedited discovery sought in Exhibit A and direct Defendants to respond to these requests promptly after ruling on this motion.

Re:	Tenet Healthcare Corp. v. Community Health Systems, Inc., et al.,
	No. 3:11-cv-00732-M (N.D. Tex.)

Dear Mr. Walters:

I write to notify you of grave concerns relating to your client, Tenet, and its advisers.

As I believe you know, employees of CHS affiliates commit to a binding code of conduct. Senior employees also typically sign additional acknowledgements, which contain confidentiality provisions. Collectively, these arrangements serve to promote integrity and lawful conduct; to protect patient privacy; and to prevent the dissemination of confidential company information. CHS and its affiliates are also successors-in-interest to similar contracts and binding legal arrangements executed by Triad employees. These legal agreements and common law agency principles continue to bind individuals even after that employment terminates.

We rely on your representation to the Court that the information in Tenet’s complaint is based on public information. (Tenet compliant at note 2, page 3.) Tenet is well aware of the federal False Claims Act procedure and jurisprudence. Nonetheless, I want to alert you that disgruntled, former employees of CHS affiliates and Triad may presently work for, or consult with, Tenet. These individuals may seek to peddle purported information about CHS or Triad, even though they are legally prohibited from disclosing such information. Some malefactors may possess stolen CHS or Triad information, which has been altered, is incomplete, or is outdated. These former employees may harbor grudges and may, with malice, attempt to harm CHS and its affiliates.

Chicago       Hong Kong      London      Los Angeles      Munich      Palo Alto      San Francisco      Shanghai      Washington, D.C.

Because the motives of such scofflaws are suspect in all events, there will be serious legal consequences for knowingly, or with willful blindness, relying on stolen or inauthentic documents, or data, in pleadings with the Court or in other public statements. As officers of the Court, we trust that you will closely scrutinize that Tenet and its advisers have taken all necessary steps to ensure that former CHS employees remain true to their legal obligations. CHS will review all claims and remedies against violators, including the striking of pleadings, seeking sanctions, and filing claims for money damages.

CHS takes its code of conduct seriously. CHS expects its employees to follow this good conduct; it will vigorously investigate and prosecute any breaches here. Moreover, CHS will investigate all potential liability for those aiding and abetting such illegal conduct or tortiously interfering with these binding legal arrangements.

To our shock, we have received troubling reports that uninvited strangers have approached CHS employees, including doctors, and asked questions under false pretenses. The doctors and other health care professionals report that strangers lied to them; falsely claimed to be CHS researchers; showed them suspect data; and asked questions about matters related to subject matters raised in your lawsuit. This letter serves as notice of these illegal and unethical pretextual practices. We trust that these pre-texting agents are not working for your firm. However, we note that your complaint in this matter relies on information from an unidentified “third party” (para 27), and couches dramatic allegations about our physicians, based on “on information and belief.” (para 90). I am confident that your firm will re-check these anonymous sources in light of this letter, and investigate the ethics and legality of their methods and practices.

Tenets and its agents must take all steps to ensure that they are not relying on illegally-obtained information. This notice is not intended to, nor should it, chill or impede any lawful, truthful evidence.

Sincerely,

Peter D. Doyle

Re:	Tenet Healthcare Corp. v Community Health Systems, Inc. et al.
No.	3:11-cv-00732-M (N.D. Tex.)

Dear Peter:

I write in response to your letter of April 21, 2011.

To begin with, although I am unfamiliar with CHS’s “Code of Conduct” or the restrictions you claim it places on current or former employees, I can assure you that neither my firm nor Tenet is engaging in “pretextual practices,” as you intimate in your letter. We would not allow or condone these practices. As you no doubt know, many people and entities unaffiliated with us — including governmental and regulatory agencies — appear to be interested in, or are actively investigating, CHS’s business practices. I can only assume that any “pre-texting,” if it exists, has been conducted by some other party. You may be assured that we are committed to prosecuting our claims by the rules and not through surreptitious information gathering. We trust that you are committed to the same standards as well.

You may further be assured that we have not relied on “stolen or inauthentic documents or data.” In this regard, you should know that we have received many unsolicited calls since the filing of the lawsuit, from a variety of sources in positions to know of such things, confirming conclusions we reached from public data and other sources. Among other things, these callers have confirmed (1) the inappropriate Blue Book admissions criteria and the admission of patients who under accepted clinical practice should be treated in observation; (2) the relentless pressures placed

on emergency department doctors by CHS hospital administrators to increase revenues by raising admission conversion rates; (3) and the concomitant pressures imposed on physicians to decrease CHS hospital observation rates. It seems these callers (who have expressed fears of retaliation) are concerned that CHS has failed to operate an effective regulatory compliance program or to treat seriously information provided by whistleblowers. In effect, these callers have confirmed (and added considerably to) what we learned before we filed our Complaint. And nothing we have learned since causes us to doubt the accuracy of a single allegation.

In truth, your letter appears to be nothing more than an overt threat intended to keep us from taking calls from CHS’ s affiliated physicians and employees who are intent on the truth emerging. Your letter also attempts to smear CHS’ s former employees as “malefactors” and “scofflaws” and to stifle the legitimate collection of important evidence. While CHS doubtlessly would prefer to further conceal its improper practices, neither Tenet nor our firm will be bullied into allowing it to do so.

Of course, please call if you would like to speak about this or any other matter.

Best regards.

Very truly yours,

Robert C. Walters
