REDACTED VERSION - PUBLICLY FILED
IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE

RELIANT PHARMACEUTICALS, INC., Plaintiff,
V. PAR PHARMACEUTICAL, INC., Defendant.

C.A. No. 06-774-JJF

DECLARATION OF JOHN G. TAYLOR IN SUPPORT OF DEFENDANT 'S MOTION TO COMPEL DISCOVERY I, John G. Taylor, declare:
I. I am a partner in the law firm of Frommer Lawrence & Haug LLP ("FLH"),

counsel for defendant Par Pharmaceutical , Inc. ("Par"). I submit this declaration in support of Par's motion to compel discovery from plaintiff Reliant Pharmaceuticals , Inc. ("Reliant"). I have personal knowledge of the facts set forth in this declaration , or I believe them to be true based upon my investigation and information provided to me by other knowledgeable persons. 2. Reliant is the holder of approved NDA No. 21-416 for Rythmolo SR brand

propafenone HCl extended release capsules . Reliant is also the current assignee of the '588 patent, which is listed in the Orange Book for Rythmol"^ SR. Par 's ANDA No. 78-540 for a generic version of Rythrnolo SR includes a paragraph IV certification for the ' 588 patent. As required, Par sent Reliant a Paragraph IV notice letter on November 7, 2006 after FDA accepted for filing Par's ANDA submission regarding 325 mg propafenone HCl extended release capsules. Par sent Reliant another notice letter on January 10, 2007 after FDA accepted for filing

Par's ANDA submission regarding 225 mg and 425 mg propafenone HCl extended release capsules. Par's notice letters contained detailed explanations of the factual and legal bases for Par's belief that the '588 patent is invalid , unenforceable, and not infringed by Par's proposed product. 3. Par's notice letters also included an Offer for Confidential Access {"OCA") to

Par's ANDA. Reliant signed and returned the OCA to Par on November 22, 2006. While Par was preparing to send its ANDA to Reliant, and with approximately one week remaining in the 45-day statutory period, Reliant sued Par on December 19, 2006. On April 25, 2007, Par sent Reliant a copy of its ANDA and samples of its proposed product in response to a letter request from Reliant' s counsel. 4. On May 30, 2007, 1 was advised by Karen Pascale, an attorney at Par's local

counsel, Young Conaway Stargatt & Taylor LLP, that she had received a call from Judge Farn. an's chambers informing her that Reliant's motion for disqualification would be decided on the papers without oral argument. 5. In a letter dated July 16, 2007, Reliant's counsel stated that "Reliant will not

produce documents or things to FLH until final resolution of Reliant's Motion To Disqualify FLH." This was the first time Reliant's counsel informed Par of Reliant's position . Reliant did not advise Par or the Court of its position on document production when it agreed to the August 24, 2007 deadline for completion of document production, even though there was a possibility that its disqualification motion might not be decided until near the end of the discovery period. 6. Counsel for Reliant and Par held a telephone conference on August 1, 2007 to

discuss discovery issues and the Court's July 25, 2007 Order denying Reliant' s motion to disqualify FLH. During that call , Reliant's counsel, Gerald J. Flattmann, Jr., stated that Reliant

was extending the deadline for completion of document production and contention interrogatories by 30 days, as allowed by the Court's July 25 Order. Mr. Flattmann also stated that Reliant was "ready to start streaming documents" to Par. When asked directly by Par's counsel, James K. Stronski, when Reliant would produce documents and amend its interrogatory answers, Mr. Flattmann said that they would get back to Par "promptly." Mr. Stronski specifically advised Reliant's counsel that Par needed to receive Reliant's documents and amended interrogatory answers by the middle of August to allow Par to move to compel, if necessary, in time to be heard on the Court's last motion hearing date before the September 24, 2007 discovery deadline. 7.

Objections and Responses to Plaintiff's First Set of Interrogatories, served June 18, 2007. 8. Attached hereto as Exhibit 2 is a true and complete copy of a letter from John G.

Dear Gerald: Enclosed is a proposed stipulated protective order to govern the conduct of discovery and the handling of protected information in this action. Please review the proposed order and let us know if it is acceptable to Reliant as soon as possible. In order to move document production along, we propose that the parties produce documents while a protective order is negotiated and treat all confidential documents produced as outside-counsel-only material until a protective order is entered. Please let us know if Reliant will agree to proceed in, this manner. Par expects to be in a position to begin producing documents responsive to Reliant's requests-in addition to the samples and ANDA already produced in April next week. Please advise us when Reliant will be in a position to begin its document production. Finally, we note that Reliant's responses to T'ar's first set of interrogatories state that your firm will be representing the inventors of U.S. Patent No. 5,681,588 C the `588 patent"). See Response to Interrogatory No. 1. We intend to tape the depositions of the inventors this Fall. Please confirm that Reliant is collecting and will produce responsive documents in the possession, custody and control of the inventors of the `588 patent and will make them available for depositions in New York this Fall. We, also intend to take the depositions of the prosecuting attorneys and individuals at Knoll, BASF and Abbott who the documents reveal to have knowledge relevant to issues in this action. Please advise us immediately whether your firm represents any of these parties and, if so, confirm that Reliant is collecting and will produce

Re:
Dear John:

Reliant Pharmaceuticals, Inc. v. Par Pharmaceuticals

I write in response to your July 11, 2007 letter to Gerald Flattmann and attached Proposed Protective Order. As you are well aware, Reliant objects to Frommer Lawrence & Haug's ("FLH") representation of Par in this matter that is substantially related to FLH's previous representation of Reliant regarding the acquisition of Rythmd' SR and the-patent-in-suit. Accordingly, as set forth in ReIiant's Objections and Responses to Par's First Set of Requests For the Production of Documents and Things, Reliant will not produce responsive documents or things to FLH until final resolution of ReIianfs Motion To Disqualify FLH.

However, to avoid further delay once the motion is decided, Reliant is willing to negotiate the terms of the Protective Order to be entered in this action. Par's proposed Protective Order contains several provisions of concern to Reliant. I will send you a redline version of the proposed Protective Order with Relianes: modifications shortly. Your reference to "prosecuting attorneys and individuals at Knoll, BASF, and Abbott who the documents reveal to have knowledge relevant to issues in this action" is uninformative. Please identify the individuals to whom you refer so that I may respond to your inquiry as to whether or not they are represented by Kirkland & Ellis.

Re: Reliant Pharmaceuticals, Inc, v. Par Pharmaceutical, Inc. Civil Action No. 06-774-JJF D.Del.

Dear Gerald:

This letter addresses Reliant ' s unilateral refusal to produce documents or substantively answer interrogatories.
Reliant's Failure to Answer Discovery Is Improper Your colleague's July 16 letter states "Reliant will not produce responsive documents or things until the motion to disqualify is resolved." t No authority is cited for Reliant's refusal to produce documents. No stay of discovery has been sought or obtained, and none would be appropriate here. And as you are well aware, Reliant agreed to the current schedule, which was incorporated in the Court's March 28, 2007 Rule 16 Scheduling Order. Not only is Reliant's continuing refusal to provide written discovery improper, but it represents a course of conduct that is contemptuous of that order, which requires that "e]xchange and completion of contention interrogatories, identification of fact witnesses and document production shall be commenced so as to be completed by August 24, 2007."2 Reliant also has not substantively answered Par's interrogatories, including those seeking information and contentions directed to infringement (Interrogatory 3), claim construction (Interrogatory 4), the identification of specific dates and documents concerning the `588 patent} and product claimed by it (Interrogatory 5), the identification of the technical areas and level of ordinary skill in the art for the '588 patent (Interrogatory 6), and the identification of objective indicia of non-obviousness concerning the `588 patent (Interrogatory 7). As an example, Reliant's failure to provide any substantive information regarding or explanation of its infringement contentions is particularly improper because Reliant has had Par's notice letters for
f July 16, 2007 letter from Christine Willgoos to John Taylor, mporzding to July 11, 2007 letter from John Taylor. 2 March 28, 2007 Rule 16 Scheduling Order, 13(a). 3 U.S. Patent No. 5,681,588.

over six months and Par's ANDA and samples of its product for over three months, Par is entitled to substantive answers to all its interrogatories now and well in advance of the August 24 cutoff. Reliant also has failed to provide basic information about the identification and representation of witnesses central to this case, and their documents. Your colleague's July 16 letter failed to respond to our July 1 I letter asking that you confirm that your firm is collecting and will produce responsive documents in the possession, custody and control of the inventors of the `588 patent and that you will make them available for depositions in New York. We assume from your silence that you are collecting those documents, that you will produce them as provided by this Court's Rule 16 Scheduling Order, and then make these witnesses available in New York for their depositions. Our July 11 letter also asked whether your firm represents the attorneys who prosecuted the `588 patent and individuals at Knoll, BASF, and Abbott with relevant information, and whether you would be producing their documents and making them available for depositions in New York, Reliant's July 16 response was that you can not respond to our inquiry because our "reference to `prosecuting attorneys and individuals at Knoll, BASF, and Abbott who the documents reveal to have knowledge relevant to issues in this action' is uninformative." The identity of the `prosecuting attorneys" is a matter of public record and are known to you: Norman F. Oblon, Esq, and C. Irvin McClelland of Oblon, Spivak, McClelland, Maier & Neustad, P.C. Please advise whether you represent them, and whether you are collecting and producing their documents as provided by this Court's Rule 16 Scheduling Order and matting them available for depositions. Regarding the "individuals at Knoll, BASF, and Abbott" referenced in our July 11 letter, Reliant has improperly withheld all documents responsive to our document requests, making it impossible for us to determine who at those companies might have relevant information.

Accordingly, we ask that you advise us immediately whether you represent anyone at these companies and whether you are collecting and producing their documents in response to our requests. In this regard, please also immediately produce all agreements relating to Reliant's acquisition of Rythmol® and the `588 patent from Abbott, including specifically any agreement

Re: Reliant Pharmaceuticals, Inc. v. Par'Pharaaaceutical, Inc. Civil Action No. 06-774-JJF (D. Del.)

Dear Jim: I write in response to your July 23, 2007 letter to Gerald Flattmann.
Your letter mischaracterizes Reliant's position with regard to discovery in this action and misquotes my July 16, 2007 letter to John Taylor. Reliant objects to FLH's continued violation of its ethical duties to its former client Reliant. Accordingly, as stated in my July 16th letter, "Reliant will not produce responsive documents or things to L'LS until final resolution of Reliant's Motion To Disqualify FLH." See July 16, 2007 letter from Christine Willgoos to John Taylor (emphasis added). If Par and FLH are truly interested in timely resolution of this matter, FLH should honor its ethical obligations to its former client Reliant and withdraw from representing Par in this substantially related matter. Indeed, Reliant has recently discovered additional contemporaneous documentary evidence that demonstrates the inaccuracy of FLH's declarations to the Court regarding its former representation of Reliant. I attach a non-privileged document' that sets forth the agenda for a June 30-July 1, 2003 meeting between Reliant and Abbott regarding Reliant's potential acquisition of the patent and drug at issue in this litigation. Arthur Hoag is listed as an attendee and described as Reliant's "IP Counsel" This document supports Reliant's assertions that FLH

The non-privileged meeting agenda attaebes a Confidential Descriptive Memorandum provided to Reliant by Abbott pursuant to a confidentiality agreement. This memorandum was previously provided in redacted force to Par as an exhibit to Reliant's briefing of the disqualification motion.

began its representation of Reliant with respect to the RythmolQD acquisition at least as early as June 2003 and that current FLH partners were involved in and have confidential information regarding that acquisition. Moreover, your request for agreements relating to Reliant's acquisition of Rythmol® and the `588 patent from Abbott further demonstrates the ethical conflict inherent in FLH's representation of Par in this matter. As admitted in Ed Haug's May 9, 2007 declaration,, FLH is already in possession of a draft of at least one such agreement, the Assignment of Patents between Reliant and Abbott. See May 9, 2007 Declaration of Edgar H. Haug In Opposition To Reliant Pharmaceuticals Inc.'s Motion to Disqualify Frommer Lawrence & Haug LLP, 21. Thus, Reliant once again requests that FLH resolve its ethical conflict by immediately withdrawing from its representation of Par. If FLH continues in its refusal to do so, Reliant may bring its newly discovered document evidencing this conflict to the Court's attention.

Regarding Reliant's responses to Par's interrogatories, Reliant maintains that its responses are appropriate for this early stage of fact discovery. As asserted in Reliant's responses, Reliant will supplement its answers to T'ar's discovery requests as discovery progresses.
Further to your inquiries regarding Kirkland & Ellis' representation of third parties to this action, as set forth in Reliant's Initial Disclosures, Kirkland & Ellis will represent Karl Kolter, Helmut Frike, Volker Bueller, Herbert Mueller-Peltzer, Thomas Moest and Claus Pich. Reliant has not represented that it has control over any of these third parties or the ability to compel their attendance at depositions in the U.S. or abroad.

Mr. Oblon has indicated that his fm will not appear voluntarily in this action. If Par chooses to subpoena any attorneys from Oblon Spivak, Kirkland & Ellis will represent them jointly with Mr. Michael McCabe of Oblon Spivak.
Sincerely,

Christine Willgoos CWllesr

Re: Reliant Pharmaceuticals, Inc. v. Par Pharmaceutical, Inc. Civil Action No. 06-774-JJF (D. Del)

Dear Gerald: Further to our August 1, 2007 telephone conference, enclosed are document subpoenas for the following individuals and companies:

1. Karl Kolter;
2. Helmut Fricke; 3. Volker Bueller;

4. Herbert Mueller-Peltzer; 5. Thomas Moest;
6. Claus Pich;

7. Abbott Laboratories, Inc.; 8. Knoll Aktiengesellschaft; and 9. BASF Aktiengesellschaft.
With respect to each of these parties, please advise us immediately whether Kirkland & Ellis represents them, whether Kirkland & Ellis accepts service of the subpoenas on their behalf, and whether they will voluntarily produce documents sought in the subpoenas and appear for depositions at mutually convenient times and places. In this regard, we repeat the request in our July 23, 2007 letter that Reliant immediately produce all agreements and related documents concerning Reliant's acquisition of Rythmol® and the `588 patent from Abbott, including specifically any agreement that concerns any right of Reliant to seek the assistance of the inventors, Abbott, BASF or Knoll (or any related person or entity) on patent, regulatory or litigation matters concerning Rythmol® or the `588 patent, and/or the obligation of the inventors,

Abbott, BASF or Knoll (or any related person or entity) to cooperate or provide assistance to Reliant on such matters.
Finally, please advise us immediately when. Reliant is going to begin producing documents and when it is going to provide amended responses to Par's first set of interrogatories. At the beginning of our August i telephone conference, you said that Reliant was "ready to start streaming documents" to us. When we asked you later during the telephone conference when Reliant would produce documents and amend its interrogatory responses, you stated that you would get back to us promptly. Although Reliant took the unfounded position that it would not produce documents until the motion to disqualify was decided, it nevertheless should have collected and prepared documents in response to Par's requests so that they could be produced consistent with the Court's scheduling orders, With respect to interrogatory responses, Reliant has not provided substantive responses to any of Par's contention interrogatories. The statement in Christine Willgoos' July 26, 2007 letter that Reliant's "responses are appropriate for this early stage of discovery" is unsatisfactory. Although Reliant may supplement its responses as discovery progresses, Par is entitled to substantive responses now. As we pointed out in our July 23 letter, Reliant has had Par's notice letters for over six months and has had Par's ANDA and samples for more than 3 months. There is no excuse for Reliant not providing substantive information in response to Par's interrogatories seeking infringement contentions.

John Taylor, Esq. F:rommer, Lawrence & Haug 745 Fifth Avenue New York, New York 10151 Re. Dear John:
I write in response to your August 8, 2007 letter to Gerald 1~ lattmann. Thank you for providing courtesy copies of the subpoenas you intend to serve. Kirkland & Ellis represents Drs. Kolter, Frike, Bueller, Mueller-Peitzer, Moest and Pich. We are not, however, authorized to accept subpoenas on their behalf. None of Drs. Kolter, Frike, BuelIer, Mueller-PeItzer, Moest and Pich are currently, or ever have been, employees of Reliant. Reliant has no control over them. However, in an effort to facilitate discovery, Kirkland & Ellis will ask them, if they would be willing to voluntarily produce documents or appear for deposition in this action in the United States.

Reliant Pharmaceuticals, Inc. v. Par Pharmaceuticals

Kirkland & Ellis does not represent Abbott Laboratories, Inc., Knoll AG, or BASF AG in this
action. Pursuant to the Court's July 25, 2007 Order, either party may extend, without leave of Court, the time to comply with paragraph 3 of the March 28, 2007 Scheduling Order by 30 days. Reliant advised you during our August 1, 2007 teleconference that it was extending that date, and thus has until September 24, 2007 to comply with paragraph 3 of the Scheduling Order. Reliant will begin its document production shortly and supplement its interrogatory responses in order to timely meet its discovery obligations. Reliant's document production will include the agreements you request, subject to the objections made in its June 11, 2007 Objections and Responses.

Moreover, although Par produced its ANDA and samples, it did so pursuant to the Offer of Confidential Access, which does not permit disclosure to experts for purposes of litigation preparation. Reliant will be in a better position to provide more complete substantive answers to Par's interrogatories once it is able to consult with its experts. Now that the Protective Order has been filed, we should be able to do that shortly. Sincerely,

153 East 53rd Street New York, NY 10022-4611 Re: Reliant Pharmaceuticals , Inc, v. Par Pharmaceutical, Inc. Civil Action No. 06-774-JJF (D. Deli

Dear Gerald; We write concerning Reliant's failure to produce any documents or to provide substantive answers to any interrogatories despite Par's repeated requests and Reliant's repeated assurances---both written and oral-that documents and interrogatory answers were forthcoming. See Frommer Lawrence & Haug letters dated July 11, July 23, August S, and August 13, 2007 and Kirkland & Ellis letters dated July 16, July 26, and August 10, 2007. During our August 1 telephone conference, we specifically advised you that we needed to receive Reliant's responsive documents and substantive interrogatory answers by the middle of August so that Par could, if necessary, make a motion to compel in time to be heard before the September 23 deadline for completion of document production and contention interrogatories. Judge Farnan's last motion hearing date before the September 23 deadline is September 21. Under Judge Farnan's individual rules, the last day a motion can be filed to be heard on the September 21 hearing date is Thursday, August 23. Accordingly, if we do not receive substantial and meaningful production of documents responsive to Par's first set of document requests and substantive answers to Par's first set of interrogatories by Wednesday, August 22, we will have no choice but to file a motion to compel on August 23.

Re: Reliant Pharmaceuticals, Inc. v. Par Pharmaceuticals

Dear John:
I write in response to your August 13, 2007 letter to me and your August 20, 2007 Ietter to Gerald Flattatann. Pursuant to the Court's July 25, 2007 Order, Reliant has an additional 30 days - until September 24, 2007 -- to comply with its discovery obligations set forth in paragraph 3 of the Rule 16 Scheduling Order. Reliant has repeatedly informed you that it intends to meet its discovery obligations prior to that date. See, e.g., August 10, 2007 letter from Christine W111goos to John Taylor.

Accordingly, any motion to compel filed by Par prior to the September 24, 2007 deadline is premature. In particular, should Par file any motions to compel on August 23, 2007, as indicated in your letter to Gerald Flattmann, such motions would be frivolous, and Reliant will move for its costs incurred in defending them.
Regarding the inquiries made in your August 13, 2007 letter, Drs. Kolter, Frike, Bueller, Mueller-Peltzer, Moest and Pich have indicated that they will not appear voluntarily in this action.

Sincerely,
