CAUSE NO. 00-2969-F ELMER L. SEWELL, etal., Plaintiffs, vs. GAF CORPORATION, et al Defendants. IN THE DISTRICT COURT OF NUECES COUNTY, TEXAS 214th JUDICIAL DISTRICT DEFENDANT CELANESE LTD/S RESPONSE TO PLAINTIFF'S REQUEST FOR RULE 194 DISCLOSURES In accordance with Rule 194 of the Texas Rules of Civil Procedure, and in response to Plaintiffs Request for Disclosures, Defendant Celanese Ltd. ("Celanese") provides the following information in relation to Plaintiff Geronimo Marroquin: (a) The correct names of the parties to the lawsuit: Celanese Ltd. is the correct name of this defendant. (b) The name, address, and telephone number of any potential parties: At this stage of the suit, Celanese has insufficient information to know if all proper parties are joined. (c) The legal theories and, in general, the factual bases of the responding party's claims or defenses: On the basis of the limited information and vague allegations contained in Plaintiffs' Petition, Celanese believes the following affirmative defenses do or may apply to this case: The sole proximate cause of Plaintiffs alleged injuries or damages were the acts or omissions of other parties or persons over whom Celanese had no control and for whom Celanese is not legally responsible. No act or omission on the part of Celanese either caused or contributed to Plaintiffs alleged injuries or damages. Further, Celanese owed Plaintiff no duty, legal or otherwise, and is therefore not liable to Plaintiff for any alleged breach of any Celanese Ltd.'s Response to Plaintiffs Request for Rule 194 Disclosures Page 1 SEWELL 194 disclosures.wpd alleged duty. As to any injuries or damages Plaintiff alleges to have incurred, Plaintiff voluntarily and knowingly assumed the risk of incurring any of the injuries or damages alleged. Additionally, Plaintiff failed to exercise ordinary care for his own safety, and such failure on his part proximately caused any injuries or damages alleged. Plaintiff's claims against Celanese are barred by the applicable statute of limitations and the doctrines of laches and waiver. Finally, it is unclear from Plaintiffs' Petition if or when Plaintiff worked at any Celanese facility, and if so, which facility. Assuming Plaintiff did perform some type of independent contractor work at a Celanese facility, Celanese denies that Plaintiff was exposed to asbestos at all, or in sufficient quantities to have caused any harm. Celanese believes its plants are and were safe and well-maintained industrial facilities, and there would have been insufficient opportunity for any such exposure. (e) The name, address, and telephone number of persons having knowledge of relevant facts, and a brief statement of each identified person's connection with the case: Please refer to the Persons with Knowledge List regarding plaintiff Marroquin which is attached hereto as Exhibit A. (f) For any testifying expert: 1) the expert's name, address, and telephone number; 2) the subject matter on which the expert will testify; 3) the general substance of the expert's mental impressions and opinions and a brief summary of the basis for them, or if the expert is not retained by, employed by, or otherwise subject to the control of the responding party, documents reflecting such information; 4) if the expert is retained by, employed by, or otherwise subject to the control of the responding party: (A) all documents, tangible things, reports, models, or data compilations that have been provided to, reviewed by, or prepared by or for the expert in anticipation of the expert's testimony; and (B) the expert's current resume and bibliography: 1.
