November 29, 2005 By Facsimile and U.S. Mail John W. Martin, Esq. Baker Botts LLP 2001 Ross Avenue, Suite 800 Dallas Texas 75201 	Re:	Perot Systems Corporation 		Schedule TO-I 		Filed November 15, 2005 Dear Mr. Martin: 	We have the following comments on the above-referenced filing: Summary of Terms, page 8 1. In Q&A Nos. 35 and 36 you recommend that option holders consult a tax professional to determine the tax consequences of the offer. Option holders may rely on the disclosure that appears in your filing, including disclosure relating to tax consequences. Please revise or eliminate the referenced disclaimers. If you wish to alert option holders that their tax consequences may differ based on their particular situation, then please revise the disclosure to clarify this fact. Also revise the similar language on page 27 that recommends to option holders that they seek the advice of their "own legal, investment and/or tax advisors if [they] have questions about [their] legal, financial and/or tax situation." Conditions of the Offer, page 30 2. The introductory paragraph addresses the company`s ability to determine whether the triggering of a condition "makes it inadvisable" to proceed with the offer. Please note that, when a condition is triggered and the company decides to proceed with the offer anyway, we believe that this constitutes a waiver of the triggered condition(s). You may not rely on this language to tacitly waive a condition of the offer by failing to assert it. Please confirm your understanding on a supplemental basis. 3. Paragraphs (a) and (b)(3) condition the offer on whether the "contemplated future conduct" or the "prospects" of the company or its subsidiaries is materially impaired. Please revise to specify or generally describe the "contemplated future conduct" and "prospects" so that option holders will have the ability to objectively determine whether these conditions have been triggered. Also revise paragraphs (d)(5) and (f)accordingly. 4. Please revise the conditions to eliminate repetition. It appears that the conditions in paragraphs (a) and (b) address many of the same situations. 5. In condition (d)(7) you state that the condition is triggered by a decline in the named benchmarks in "any time period after the close of business on November 15, 2005." Please revise to clarify how the decline is determined Effect of a Merger or Acquisition Before We Grant Replacement Options, page 34 6. Here and elsewhere in the document you discuss what may happen to tendered options "if [you] merge into or are acquired by another company after [you] accept eligible options for exchange in the Offer but before we grant the replacement options." As there are currently only five calendar days between the scheduled expiration of this offer and the date you intend to issue replacement options, revise this language here and throughout the document to clarify the risk to option holders. General Terms of Replacement Options . . . , page 34 7. Confirm, if true, that you have summarized all material terms of the replacement options and the eligible options, and that you have summarized all material difference between the two options. Revise the offer to eliminate the disclaimer on page 39. Material U.S. Federal Income Tax Consequences, page 45 8. Please eliminate the qualifier that this disclosure is "a general summary." Also, eliminate qualifiers such as "we believe" and "generally" and the disclaimer in the penultimate sentence of the first paragraph. The current disclosure suggests that security holders may not rely on the description of material tax consequences included in the document. 9. Revise this section to affirmatively state the tax consequences of the exercise of the amended options. It appears you should revise the summary term sheet to highlight this tax effect. 10. Revise to eliminate the IRS Circular 230 Disclosure disclaimer or tell us why you believe it is applicable. Additional Information, page 47 11. Schedule TO does not specifically allow you to forward incorporate disclosure in subsequently filed documents. In fact, doing so is inconsistent with the technical requirements of General Instruction F of Schedule TO and your obligation under Rules 13e- 4(c)(3) and 13e-4(e)(3) to amend the Schedule to reflect a material change in the information previously disclosed. Please revise the second and third paragraphs of this section, and the similar disclaimer in the section entitled "Forward-Looking Statements" accordingly.
