SECOND AMENDED OPINION AND ORDER MUKASEY, District Judge. This litigation arises out of an abortive June 1982 tender offer by Gulf Oil Company (“Gulf”) for the stock of Cities Service Company (“Cities”). The defendants are Gulf, a Pennsylvania corporation engaged in oil and gas exploration, production and marketing, GOC Acquisition, a wholly-owned Delaware subsidiary of Gulf created to implement the tender offer for Cities, and various individuals, all directors and/or officers of Gulf at the time of the tender offer. In 1984, Chevron Corporation, parent of defendant Chevron U.S.A. Inc., acquired Gulf Corporation, parent of Gulf Oil Corporation. At the time of the tender offer, Cities was a Delaware corporation with its headquarters in Oklahoma. Cities ultimately became a wholly-owned subsidiary of Occidental Petroleum Corp. on December 3, 1982. In an opinion dated September 23, 1986, as amended in an order providing for notice to the class, Judge Kram certified a class consisting of All persons or entities who during the period June 17, 1982 to and including August 7, 1982: (1) tendered shares of Cities Service Company (“Cities Service”) common stock to ... Gulf Oil Corporation ... pursuant to a tender offer made on June 22, 1982; or (2) purchased Cities Service common stock; or (3) purchased call options on Cities Service stock. The class complaint includes (1) those who tendered their Cities shares to Gulf, (2) those who purchased Cities’ shares from June 17, 1982, when Gulf announced its proposed acquisition of Cities, to August 7, 1982 when Gulf terminated the tender offer and (3) those who purchased call options on Cities’ stock from June 17, 1982 to August 7, 1982. For ease of reference, I will refer to this complaint as the Class complaint and to these plaintiffs as the Class plaintiffs. In a complaint filed December 16, 1987, a group of class plaintiffs opted out of the class and filed their own complaint. The opt-out plaintiffs owned beneficially almost 3,800,000 or about 5% of the total common shares of Cities outstanding as of the date of the tender offer. They tendered their shares in response to Gulf’s June 22, 1982 offer for over 50% of Cities shares, the first step in its proposed acquisition of Cities. These plaintiffs are W. Alton Jones Foundation, a not-for-profit New York organization, Wenonah Development Company, a Delaware corporation, and Foster & Foster, a Connecticut partnership whose individual partners include plaintiffs Foster Bam, a former Cities director, and his mother, Alma Foster Davis. Bam and Davis are also plaintiffs in their capacity as co-trustees of testamentary trusts under the wills of four deceased member of the Foster family. For ease of reference, I will refer to these plaintiffs as the Jones plaintiffs. Although the plaintiff class is no longer unified, the two complaints are similar and have been consolidated for all purposes. The Class plaintiffs allege breach of contract and violations of § 14(e) of the Securities Exchange Act of 1934, 15 U.S.C. § 78n(e), § 10(b), 15 U.S.C. § 78j(b) and Rule 10b-5 thereunder. The Jones plaintiffs allege breach of contract and common law fraud as well as violation of § 14(e). In early 1988, defendants moved to dismiss the complaints, for failure to plead fraud with particularity as required by Fed.R. Civ.P. 9(b) and for failure to state a claim for contract breach. On September 14, 1988, defendants also moved for summary judgment. At a September 29, 1988 conference I permitted full discovery, while allowing defendants to pursue their motions as discovery continued. Both sides have modified their arguments at various points in the briefing. Therefore, to the extent this opinion presents the parties’ positions, it deals only with their final positions, not with the detritus of every argument presented and then abandoned in the 900 or so pages of briefs the parties have inflicted on the court. The motions are granted in part and denied in part, as set forth below. I. A bidding contest for control of Cities was begun on June 1, 1982 when, in response to a proposal for a friendly takeover of Cities for $50 per share made by Mesa Petroleum Corporation (“Mesa”), which had been accumulating Cities stock for two years, Cities commenced its own tender offer for Mesa stock at $17 per share. Mesa countered with a hostile tender offer for 15% of Cities at $45 per share. Fearing that a takeover by Mesa was imminent, Cities sought a “white knight” armed, inter alia, with a higher bid than Mesa’s. The white knight was Gulf. Early on the morning of June 17, 1982, the chief executive officers of Gulf and Cities agreed in a telephone conversation that, subject to Board approval, Gulf would tender for 51% of Cities at $63 a share. (Lee Dep. 228) Gulfs offer was to be followed by a merger of the two companies, at which point Cities’ then unpurchased 49% stock interest in Gulf would be converted into Gulf debentures at $63 per Cities’ share. (Merger Agreement § 2.1) Later that morning, Gulf’s Board unanimously authorized the acquisition. (DX 8) The plan unravelled over the summer, as the Federal Trade Commission (“FTC”) objected to the deal, and then sued successfully to block it. Faced with an FTC demand that Gulf forfeit Cities’ Lake Charles, Louisiana refinery, Gulf invoked a “litigation out” in the Offer to Purchase plaintiffs’ shares which allowed it to terminate the deal if “action taken ... by any United States federal ... governmental authority ... in the sole judgment of the Purchaser ... would require the divestiture ... of a material portion of the business ... of the [Cities] Company.” (Offer to Purchase at § 15(d)) Plaintiffs argue that Gulf soured on the deal earlier in July, and then negotiated in bad faith with the FTC precisely to force the FTC to seek to enjoin the transaction so that Gulf could take advantage of the “litigation out” in the Offer to Purchase. Then, plaintiffs contend, after the FTC had sued and demanded divestiture of the Lake Charles refinery, Gulf in bad faith refused to agree to the divestiture, even though the Lake Charles refinery was not important to it and thus not “material” within the meaning of § 15(d) of the Offer to Purchase. A. The Lake Charles Refinery According to plaintiffs, Gulf’s purpose in acquiring Cities was to obtain Cities’ domestic oil and gas reserves, so-called “upstream” assets. Replacing Gulf’s depleting domestic reserves had been a management priority for some time. (Mahaffey Dep. 13-14; Murdy Dep. 14-15; PX 43; PX 7) Furthermore, according to plaintiffs, acquisition of Cities’ downstream assets (refining, marketing and transportation), including the Lake Charles refinery, was viewed by Gulf as a negative aspect of the merger: as plaintiffs allege Gulf’s chairman James E. Lee stated, it was “one of the cons.” (Lee Dep. 271) Cities’ lawyer Martin Lipton recalls Gulf representatives saying that they ascribed “no value” to the Lake Charles refinery. (Lipton Aff. ¶ 6) According to plaintiffs, Gulf had severe losses in its own refining and marketing operations and was not pursuing Cities’ downstream assets. (Wilder Dep. 18-19, 230-31) In fact, Gulf had decided that “we really needed to reduce refining capacity.” (Lee Dep. 50-51); to that end, Gulf in 1981 considered selling or shutting down several of its refineries. (Lee Dep. 48-55; Mahaf-fey Dep. 234-35) Defendants do not deny that Gulf wanted Cities’ oil and gas reserves. However, defendants claim that Cities’ only refinery — the Lake Charles refinery — was of interest also because it could process low-cost heavy sour crude, the least expensive crude in the market, into 100 percent unleaded gasoline, a capability in which Gulf found itself wanting. (Lee Dep. 12-17) Gulf’s outside counsel Daniel I. Booker of Reed Smith Shaw & McClay avers that Gulf General Counsel Jesse P. Luton told him on June 18 that Lake Charles could not be divested under any circumstances. (Booker Dep. 91-92) Defendants assert that every Gulf director has supported Lee’s view that Lake Charles was crucial. (See Gordon Dep. 24; Singer Dep. 89; Co-lodny Dep. 94; Goodman Dep. 99; McAfee Dep. 94-95; Dickey Dep. 122-23; Higgins Dep. 65; Scully Dep. 106) At the time, Cities Chairman Charles Waidelich stated that the Lake Charles refinery would fit “very, very nicely to [Gulf’s] needs ... our [Cities’] refinery is going to be very integrated into theirs [Gulf’s].” (PX 23 at 2-3, Riley Wilson interview of Charles Waide-lich, June 22, 1982) Furthermore, Cities, in its response to the FTC’s demand for a specification of benefits to Gulf and Cities from the transaction, stated that, “The benefits of the union of these two companies are enormous. The major ones include: ... The new units at Lake Charles will fit well with some of Gulfs needs.” (DX 41 at 36) Finally, Campbell, of the FTC stated at his deposition, I recall the phrase crown jewel was used, that Gulf considered the Lake Charles refinery so important that it was the crown jewel of the acquisition. (Campbell Dep. 165) Accordingly, defendants claim they were justified in terminating the deal in August when the FTC demanded that Gulf sell Lake Charles. Plaintiffs question whether Lake Charles in fact was important to Gulf, citing the following: (i) Booker, Gulf’s outside counsel, did not tell Cities’ lawyer Bertram Kan-tor or the FTC about the do-not-divest instruction (Booker Dep. 94-97, 196-97, 203-04); (ii) Lee avers that he told the Gulf Board about Lake Charles at the June 17 meeting, although the minutes reflect no mention of it until the July 13 Board meeting (PX 62); (iii) Gulf valued Cities’ entire array of downstream assets at $564 million, later reduced to $350 million (PX 42 at 2) and one Gulf document records Gulf’s original Lake Charles valuation at $140 million (PX 229), which was below the $200 million (4% of the total value of the merger to Gulf) that Gulf General Counsel Luton told the Gulf Board could be considered a benchmark for measuring a “material” asset; and (iv) Gulf had rejected as unjustified five or six years earlier the idea of a sour crude upgrading project at Gulf’s Port Arthur refinery (Mahaffey Dep. 389-92, 614-17), and such a project was never pursued after Gulf terminated the Cities offer. Id. at 391. Plaintiffs also question Gulf’s estimate of the cost of divesting Lake Charles: (i) Gulf’s estimate of $245 million in costs it might incur if it agreed to divest Lake Charles (PX 143) is based on the unsupported claim that Gulf would sell the refinery for zero, with no attempt to contact companies that had expressed an interest in buying downstream assets to see if they might be interested in Lake Charles; (ii) Gulf’s total cost estimate of $1 billion, arrived at by including lost opportunity costs, was admitted to be “soft” by Lee who instead suggested that $500 million was a better figure (Lee Dep. 85-89); and (iii) Divestiture of Lake Charles would have helped Gulf’s post-acquisition income and cash flow by reducing its debt burden and interest costs. According to plaintiffs, concern over the high debt that would result from the merger led Gulf executives to contemplate divestiture of all or part of Cities’ downstream assets, further undermining defendants’ position that Cities’ refinery at Lake Charles was the “crown jewel” of the deal. Thus, both Lee and Gulf Executive Vice President and Director Harold H. Hammer told Standard & Poor’s of their determination to “vigorously pursue necessary divestments — both Gulf and Cities.” (PX 99 at 1) Hammer told Duff & Phelps, another bond rating agency, that Gulf “would be prepared to sell Cities downstream properties — in total — if we could find a purchaser who would take responsibility for the people as well.” (PX 102 at 2) Cities Chairman Waidelich recalls that Lee told him that Gulf would consider divesting one of its refineries, probably the Philadelphia refinery, after the merger. (Waidelich Aff. ¶ 6) Finally, Gulf’s lawyers at the July 30 injunction hearing allegedly described as “minuscule” the assets challenged by the FTC, although this appears to have been little more than legal puffery designed to downplay the import of the antitrust problems. B. Possibility of Antitrust Problems Both sides concede that FTC antitrust scrutiny was expected. Defendants maintain that the only antitrust problems foreseen by both companies were in gas marketing operations in the eastern part of the country, and that no one foresaw that the FTC would order sale of a major refining asset like Lake Charles. (Booker Dep. 71-72, 84-86, 126, 143, 413-15; Colodny Dep. 45-47, 96-97, 240, 293-295; Evans Dep. 213-15; Goodman Dep. 37-40) To support this proposition, defendants cite a public statement by Cities Chairman Waidelich: [W]e think the antitrust problems, if there are any, are not going to be serious and will be manageable.... [B]ased on what we believe to be gasoline marketing share, there are probably several states in the southeast, maybe in the northeast, where according to the guidelines of the government, this merger may stretch those guidelines and we might have to do some modest divesting of marketing facilities. I do not believe there will be any problem with any of our other operations from an antitrust standpoint, although the government can surprise us, of course, anytime. But we just feel gasoline marketing is really the only area where we will have any great problem. (PX 23 at 3-4) Precisely because Gulf feared that the FTC might “surprise” the parties, Gulf added to the Offer to Purchase § 15(d) under which Gulf could terminate or postpone “regardless of the circumstances” giving rise to the FTC suit including “any action or inaction by ... Gulf.” That section left to Gulfs “sole judgment” the decision whether the FTC was demanding divestment of a “material” portion of Cities’ assets. Defendants contend that the statements in the Offer to Purchase which referred to antitrust questions were warnings required by the securities laws that put plaintiffs on notice that the deal was highly contingent, not promises by Gulf that everything would come out all right in the end: [Gulf] expects that a review of the Offer by the FTC ... will focus particularly upon the petroleum refining and marketing operations and markets of Gulf and [Cities]. Gulf believes that the combined petroleum refining and marketing operations of Gulf and [Cities] do not create a likelihood of antitrust challenge such as would prevent the consummation of the Offer. There can be no assurance that a challenge to the Offer on antitrust grounds will not be made, or if such a challenge is made, what the result will be. See Section 15 for certain conditions to the Offer, including conditions with respect to litigation and certain governmental actions. (Offer to Purchase at § 16(c)) In a description of the Merger Agreement placed in the Offer to Purchase, the shareholders were also warned that, although the parties would use their “best efforts” to effect the merger, “there can be no assurance that the merger will take place, since ... it is subject to certain conditions, some of which are beyond the control of Gulf or the Company.” (Offer to Purchase at § 11) Plaintiffs read these provisions differently. They claim that the statement that Gulf “believes that the combined petroleum refining and marketing operations” would not present an antitrust problem and that Gulf would use its “best efforts” were carefully written to convey, albeit in code, an alleged secret oral representation by Gulf that it was willing to divest any downstream assets, including Lake Charles, to satisfy the FTC. According to Cities’ lawyer Henry Lesser, these statements in the Offer to Purchase reflectpng] Gulf’s commitment to take whatever action, including divestiture, was necessary to resolve FTC antitrust concerns about downstream assets.... I ... understood that, in particular, Gulf and its counsel considered the language to be an accurate reflection of its perception that the FTC would have significant concerns about the effects of combining the downstream operations of the two companies, and of Gulf’s anticipated strategy for preventing those concerns from disrupting its acquisition of Cities. Id. at ¶ 5. To support this claim, plaintiffs’ lawyer, Martin Lipton, avers that when Hammer first spoke with him on June 14 about the possibility of Gulf acting as a white knight, Lipton raised possible antitrust problems. “Hammer replied, in words or substance, that Gulf had studied the antitrust implications of a merger backwards and forwards and that Gulf would divest Cities’ entire downstream operations (meaning refining and marketing operations) if necessary to cure any antitrust problems.” (Lipton Aff. ¶ 3) Plaintiffs allege that in fact the only antitrust analysis by Gulf at that point had been done by a law student intern. During negotiation of the Merger Agreement, Cities expressly raised antitrust problems regarding the combined downstream operations. According to Lipton, “[throughout the negotiations, Gulfs representatives displayed little or no interest in the value of Cities’ downstream assets.” (Lipton Aff. 11 5) Furthermore, Lipton states that on June 16 Gulf’s representatives made statements which, in the context in which they were made, conveyed the message expressly or by implication that Gulf was willing to divest some or all of Cities’ downstream assets to the extent required in order to obtain government antitrust approval. These statements included statements by the Gulf representatives that they did not want to waste time on antitrust issues and that Gulf had no interest in Cities’ downstream operations. Id. at ¶ 6. Plaintiffs have provided the court with corroborative affidavits (Kantor Aff. MI 3, 4; Lesser Aff. MI 3, 6) and other evidence, including (i) a Gulf memorandum dated June 17 and prepared by Gulf’s in-house counsel Frank W. Morgan which states that “Gulf is prepared to enter into arrangements to divest any offending assets” to secure antitrust clearance (PX 22 (emphasis added)); (ii) a June 7 analysis sent to Hammer from Charles Bowman in which he listed companies that might be interested in acquiring some or all of Cities’ downstream assets, including Lake Charles (PX 13 at 3); (iii) notes of a June 23 meeting which records Lee saying “//'[Gulf is] allowed [by the FTC] to keep Lake Charles ...” (Van Meter Aff. U 4 (emphasis added)); and (iv) minutes of Cities’ board meeting at which the merger was approved, noting that “Gulf was prepared to make curative divestitures to remove any antitrust objection to the Merger Proposal” and that, given Gulf’s willingness to make “necessary divestitures,” it was likely that the transaction would be “consummated without undue delay.” (PX 19 at 1-2; see also Waide-lich Aff. MI 4, 5) C. Gulfs July 13 Board Meeting Plaintiffs claim Gulf soured on the deal for several reasons in July, and sought an “out” even before the FTC demanded divestiture of Lake Charles. Chief among them allegedly was a shortfall Gulf’s engineers found in Cities’ oil reserves, the assets that most interested Gulf. On July 1, a Gulf task force discovered what it thought were “discrepancies of considerable magnitude” between Cities’ actual oil reserves and the level represented in Cities’ financial statements. (Lee Dep. 349-53) This was a “shock and surprise” to Lee (Id. at 351), and was promptly discussed at a Gulf meeting on July 5 which focused on whether this reserves shortfall gave Gulf an “out” from the offer, although Gulf representatives strenuously deny that Gulf was actually considering terminating the offer at that point. (Mahaffey Dep. 140-42) The Merger Agreement and Offer provided that Gulf could terminate in the event Cities misrepresented its assets in the oil or gas reserves. (Merger Agreement at § 4.6; Offer to Purchase at § 15(e)) By July 7, however, it appeared that Cities had not misrepresented its oil reserves; rather, the alleged shortfall was attributable to “an engineering opinion difference” and Gulf “might have trouble proving Cities wrong” in its calculations. (PX 57) Second, plaintiffs point out that the Offer and its $63 a share price tag generated criticism from shareholders (PX 58), from Wall Street (Wilder Dep. at 251), and from rating agencies such as Standard & Poor’s and Duff & Phelps, which threatened to reduce Gulf’s credit rating. (PX 24, 35, 48, 70) Gulf’s stock fell $3.25 the day after the deal was announced which “surprised and disappointed” Gulf Chairman Lee. (Wilder Dep. 252; PX 30) A third problem that arose in late July was the threatened loss of a tax benefit from the merger of close to $800 million, which Gulf had counted on. On July 1, Gulf learned that Congress was about to eliminate favorable “partial liquidation” tax provisions. (Moffett Dep. 147-48) The availability of tax relief remained in doubt throughout July as Gulf tried to have a “grandfather clause” inserted in the legislation to preserve the partial liquidation treatment for pre-July 1 merger agreements. (PX 83; Morgan Dep. 478; Luton Dep. 508-09) Fourth, on July 10, the failure of OPEC members to reach price agreements led to predictions that crude oil prices would fall, further reducing the value of Cities’ reserves. (PX 63) Gulfs offer of $63 a share anticipated rising prices. (Mahaffey Dep. 105-6) After the July OPEC meetings, Gulf had to assume that the price of oil “will remain flat” over the next five years. (PX 98 at 2, item (4)) According to plaintiffs, these negative factors led Gulf to reexamine its commitment to the deal. The Board at a July 13 meeting, after hearing a presentation on the oil reserves shortfall and discussing the prediction of a drop in crude oil prices, left the decision whether to proceed with the offer “in limbo” in the words of Gulf Chairman Lee. (Lee Dep. 397) Defendants argue that plaintiffs distort Lee’s testimony. Here is Lee’s full testimony on this subject: Q. Did the board consider at that point the subject of terminating the merger agreement, based upon the discrepancy in the oil reserves? A. I don’t think I would characterize it as consider terminating. We looked at the options that were open, asked counsel again about the options that were open, and decided to put the matter in abeyance for the time being, pending all the rest of the work that was going on relative to reviews, but with the intent of keeping all of our options open. [five page gap] Q. What summary did you give? A. I don’t remember exactly what I did say at that point. I think, as I said earlier, that I said that if we proceeded with this merger, that one of the first things that we would do, that I would want to see done, would be a complete in-depth review of those reserves of their oil and gas done by DeGolyer & McNaughton. But as I sit here today, I can’t tell you what else I did say. Q. You prefaced that by saying “If we proceeded.” A. Yes. Q. Was a decision made to proceed at that meeting? A. The decision was put in limbo. I never put that to the directors, the question of whether we should proceed or not. It was left to be decided later. Both sides agree that one director — Edwin Singer — urged at this meeting that the deal be scrapped. (Singer Dep. 79) D. Negotiations With the FTC Plaintiffs argue that, after July 13, defendants tried to goad the FTC to sue to enjoin the transaction, and then resisted only half-heartedly when the FTC did sue. According to plaintiffs, Gulf triggered the Hart-Scott-Rodino Antitrust Improvements Act’s (“HSR”) ten-day waiting period prematurely, changed lawyers at the last minute, failed to propose any remedy for the FTC’s principal antitrust concern— the kerojet (jet fuel) market problem, and refused the FTC’s request for an extension of time, even though Gulf’s negotiator felt a settlement was imminent and its outside counsel had forwarded a draft agreement. According to plaintiffs, Gulf triggered the 10-day HSR waiting period on July 19 even though it knew from prior FTC inquiries that the agency had serious concerns about the merger, including a “great concern” about a kerojet problem “tied to refinery.” (PX 73 at 2) Plaintiffs argue that delay would have given Gulf a greater chance to develop remedies for the FTC’s antitrust concerns. Moreover, Gulf changed lawyers on July 15, bringing in William Jentes, a litigator at the Chicago firm of Kirkland & Ellis to replace Booker, a partner at Reed Smith Shaw & McClay. Kantor avers that Booker had developed an “excellent rapport with the FTC staff,” while Jentes’ first encounter with the FTC was “adversarial.” (Kan-tor Aff. H 13) The FTC’s Marc G. Schild-kraut stated at his deposition that he “wasn’t pleased to see [Jentes] arrive,” having apparently had an earlier impression of him as “difficult to negotiate with.” (Schildkraut Dep. 82-83, 79-80) Moreover, the change caused a delay so that Jentes could learn the facts. (Booker Dep. 336, 340) Plaintiffs dilate endlessly on Gulfs supposed inadequacies in failing to devise an acceptable strategy in the negotiations with the FTC before the July 29 deadline, and in failing to agree to an extension of time beyond July 29. In summary, they argue that Gulf, aware of the FTC’s keen concern about the kerojet refining capacity of a merged entity (PX 73 at 2; PX 82 at 1; PX 85 at 1), considered and rejected a solution known as a Pasco remedy — a committed supply contract that would allow Gulf to sell kerojet production from Lake Charles at market prices for a few years (Jentes Dep. 552-53, 559-60, 599-600; PX 90; Mahaffey Dep. 328-29) — even though the director of the FTC’s Bureau of Competition, Thomas Campbell, was favorably disposed toward a Pasco remedy. (PX 106 at 2, item 3) Plaintiffs argue that Gulf was adversarial, particularly in a July 26 letter to the FTC, when it should have been conciliatory (PX 95; Kantor Aff. ¶1¶ 13, 14), declined to extend the FTC’s time to consider alternatives to a lawsuit at a time when negotiations looked promising (PX 101 at 9-10; Lee Dep. 181; PX 91 at 3-6; PX 104), delayed efforts to line up purchasers even for assets Gulf knew would have to be divested (Murdy Dep. 200-03), and otherwise dragged its heels. Plaintiffs also cite record evidence that Gulf’s waning enthusiasm for the deal weakened its stance toward the FTC, including Jentes’ report of “serious consideration” of Gulf “not going forward” if the FTC sued (Jentes Dep. 495, 504-05, 611-12), one employee’s record of a rumor of “[mjanagement having second thoughts[;] [FTC suit] might be graceful way to back out,” (PX 92; Todd Dep. 84), Jentes’ purported view that “a preliminary injunction may not be the worst thing in the world,” (Campbell Dep. 86-87; 120-22,137-38), and a statement by a Gulf representative to Campbell of the FTC that Gulf might not resist a preliminary injunction. (Campbell Dep. 131-32) Further, plaintiffs claim that Gulf purposely pursued an unproductive strategy of meeting with individual FTC commissioners, failing to propose alternatives after the July 26 letter, and not meeting with the FTC from July 28, when the commission voted to sue, until August 3, four days after a temporary restraining order (TRO) issued. Plaintiffs allege that Gulf did not resist a TRO on July 29 because it was having second thoughts about the merger. To support this contention, they note that Campbell testified that he believed Gulf had decided not to contest the TRO (Campbell Dep. 137-140), and that, after the hearing had ended, Gulf’s lawyer Donald Kempf told him that “things were up in the air.” Id. at 268. Furthermore, they allege that a July 29 Gulf Board Executive Committee meeting was largely taken up with possibilities for terminating the deal, not with fighting the injunction. According to Director Singer, the Committee was told that the kerojet problem seemed “insurmountable” and that the situation “looked dark.” (Singer Dep. 110) Plaintiffs claim that the beginning of the Board meeting the next day was similarly gloomy as Board members were advised of possible liability if the deal was terminated: Lee testified that “in the early part of this meeting, my sense was that we were leaning in the direction of termination.” (Lee Dep. 481-82) By the end of the meeting, however, after a report from Jentes in which he stated that he “was very, very, close to reaching an agreement,” “the mood of the meeting changed at that point” and the Board voted unanimously to postpone purchase of shares until August 9 and thus continue the deal. {Id. at 481, PX 123 at 8) Plaintiffs infer from this sequence that the Board realized at some point it was open to massive liability if it did not make at least one more effort at settlement. Although Gulf’s lawyers then were allowed to contest the injunction, Gulf had no firm intention to close the deal even if there was an FTC settlement; as Lee testified, if Gulf settled with the FTC, Gulf would “consider the matter again” before closing the deal. (Lee Dep. 483-84) On August 3, the FTC demanded divestiture of the Lake Charles refinery. No Cities lawyers attended that meeting. Jentes complained at the meeting that Campbell had reneged on his promise that a Pasco remedy would be acceptable; Jentes refused to agree to a sale of Lake Charles. (Jentes Dep. 815) Jentes scheduled a second meeting that afternoon with the FTC and invited Cities’ Kantor. (Jentes Dep. 815-16) At this second meeting, Jentes submitted a draft consent order with a Pasco remedy. According to Kan-tor, this order was “totally inadequate” because it limited the supply contract in two ways: the price would be keyed not to the market but to prices charged by Gulf elsewhere, and the remedy would apply to only 40% of combined production of kero-jet. (PX 132 at 7-8; Kantor Aff. ¶ 38) According to Kantor, this proposal “left Gulf entirely in control and provided the FTC with no protection against Gulfs anti-competitive conduct with respect to jet fuel.” Id. Plaintiffs aver that Gulf added insult to injury by giving the FTC only 24 hours to respond. Plaintiffs point to handwritten notes by Gulfs director Colodny showing that Lee on August 3 said that Gulf wanted to “break off negotiations” with Campbell. (PX 133) It was at the August 3 afternoon meeting that Campbell said Gulf had not negotiated “in good faith” and had “sought [the] TRO.” (PX 134, Morgan Dep. 610-12) Campbell rejected Gulfs proposal in an August 4 letter. (PX 137) According to plaintiffs, although the FTC left open an alternative divestiture of a Gulf refinery, for example refineries at Port Arthur, Alliance or Philadelphia, rather than the Lake Charles refinery (PX 136; Hardie Dep. 565; Morgan Dep. 651; DX 97 at 2; DX 98 at 2 (“Any comparable refinery to Lake Charles — Port Arthur would be acceptable — even if it is a less efficient refinery”)), Gulfs position was that it would not consider divesting any refinery. Plaintiffs aver that sale of a Gulf refinery would have cut Gulfs admitted refinery over-capacity. Indeed, plaintiffs cite statements by Gulf in late July that Gulf would sell a refinery after the merger was complete. As Gulf told Standard & Poor’s on July 26, “Gulf Oil would like to keep Cities Service’s Lake Charles refinery. If they were allowed to keep it, they would attempt to sell or close one of their other major refineries (i.e. Philadelphia).” (PX 97 at 4) Waidelich states that, at this point, he called Lee on August 4 and reminded Lee of his commitment to divest any refinery necessary. (Waidelich Aff. 1112) Waide-lich offered to adjust the offer price to take into account this loss. Id. The next day, according to Waidelich, Lee and Hammer attempted to renegotiate a “shopping list” of items in order to continue with the merger, including the transaction’s tax treatment. Id. at If 14. Plaintiffs allege that the August 6 Board meeting at which the decision to terminate was made was taken up mostly with non-FTC reasons to end the deal. Needless to say, defendants paint a far different picture of events leading up to the deal’s termination. In their view, there was no premature commencement of the 10-day HSR period; rather, long negotiations preceded that step, progress toward FTC approval was apparently being made, and counsel anticipated resolving the FTC’s remaining objections within the 10-day HSR period. (Booker Dep. 127, 134-35, 147, 326-27; Booker Aff. 1111 10, 13; Morgan Aff. 1Í1Í 8, 10, 12, 13) They attribute Gulf’s change of counsel to a desire for more experience and “more gray hair.” (Luton Dep. 95; Evans Dep. 334; Jentes Dep. 6, 9; Booker Dep. 116, 130) To the plaintiffs’ swarming attack on Gulf’s strategy in negotiations with the FTC, defendants respond with a swarming defense. They deny being aware until July 23 that kerojet refining capacity was the FTC’s main problem with the deal or that the FTC would seek refinery divestiture. (Booker Aff. ¶ 7; Booker Dep. 243-46; Jentes Dep. 253-55; Luton Dep. 171-72; Morgan Aff. ¶ 18; DX 49 at 3; Henderson Aff. K 25 n. 14) They deny that the FTC’s position was obviously serious even then. (Jentes Dep. 254, 270-71, 391, 516-17; Goold Dep. 223, 227, 244; Morgan Aff. ¶ 18) They insist that Gulf had ample basis to contest the FTC’s definition of the kero-jet market. (George Hay Aff.; Booker Dep. 484-85; DX 121 at 610) Defendants offer evidence challenging the FTC’s receptiveness to a Pasco remedy (Schildkraut Dep. 196-97; Campbell Dep. 473) and illustrating Jentes’ flexibility in proposing one, notwithstanding that he had to check with Gulf executives before suggesting a long-term arrangement. (Booker Dep. 493, 498; Hammer Dep. 435-37; Morgan Dep. 714-15) Whether the Pasco remedy might have been accepted if proposed earlier or in more detail remains an open question. Certainly the FTC did not react negatively to it until after the TRO issued. (Henderson Aff. ¶ 65) Defendants’ response to the claim that Gulf was combative when it should have been conciliatory, and vice-versa, is what one might expect. Thus, evidence is adduced that it was the FTC and not Gulf that rejected settlement before the TRO was in place on July 29 (Morgan Aff. ¶¶ 14, 21; Campbell Dep. 349, 512; DX 82), that the FTC presented no proposed remedies on June 26 and 27 (Jentes Dep. 526-27; 536-37; Goold Aff. ¶¶ 13-8), that the FTC’s Campbell did not provide the Commission’s (as opposed to his own or the staff’s) views on what was needed for approval until July 28 (Goold Aff. ¶ 15; see also Jentes Dep. 526-27, 536-37; Goold Aff. ¶¶ 3-8, 16; DX 76 at 2; DX 80 at 2), that it made no sense to suggest divesting refineries until Gulf knew what the FTC wanted to achieve, that Cities’ lawyers who are now critical of Gulf’s negotiating position supported it at the time (Morgan Aff. ¶¶ 15, 17, 19; Goold Aff. ¶¶ 14, 47; Jentes Dep. 204-05; Booker Aff. ¶ 12), and that a strategy involving delayed purchase of the tendered shares risked liability and the appearance that Cities and Gulf were colluding to the detriment of shareholders. (Morgan Dep. 755, 769) To plaintiffs’ contention that Gulf did not oppose the TRO, defendants note that the FTC’s chief litigator at the hearing, David Shonka, told Campbell that Gulf “fought it [the TRO] hard.” (Campbell Dep. 443, 444) Concerning the July 30 Gulf Board meeting, defendants confirm that, although the tenor of discussion early on favored termination, Jentes’ advice that further negotiations might prove fruitful swayed the Board. Defendants admit that the Board discussed in depth the possibility of termination. Moreover, defendants admit many of plaintiffs’ claims that Gulf had found other problems in the proposed merger in July. Specifically, defendants note that due diligence evaluation of Cities after June 17 had uncovered many adverse aspects of Cities’ financial condition including potentially extensive environmental liabilities, an apparent overstatement of some 41 million barrels of Cities proved developed oil reserves (one of the principal attractions of Cities for Gulf), a commitment to expend over $100 million on a Cities’ headquarters building in Tulsa and a risk of loss of valuable tax benefits if the merger were delayed beyond October 1. (Defendants’ April 14, 1989 Reply Memorandum at 6, 160-61) Even conceding these other problems, defendants claim that Cities knew the FTC’s August 3, 1982 demand for the Lake Charles refinery was a legitimate reason for Gulf to terminate. The August 3 demand for divestiture of Lake Charles within two years was a complete turnaround from Campbell’s earlier willingness to consider a Pasco remedy for Lake Charles. As Goold put it, Mr Jentes and I expressed shock at the new FTC terms, pointing out they were a radical departure from the July 28 position. Mr. Jentes read aloud my notes of Mr. Campbell’s statement on July 28 ... and asked Mr. Campbell, wasn’t this the position of the FTC last Wednesday? Mr. Campbell confirmed that my notes were accurate, but stated that he had new instructions from the Commissioners. (Goold Aff. ¶ 24) When Campbell stated that he believed Gulf was not acting in good faith at the afternoon meeting on August 3, Kantor replied that the divestiture demand was disproportionate to the alleged antitrust problem — an overlap in the kerojet market which was less than 4% of the refinery’s output — and otherwise defended Gulfs conduct. (DX 97 at 4). He stated: “[The] [pjunishment has to fit the crime_ [The[ [p]roblem is my fingernail, but you want to cut off my head.” (DX 97 at 3) He also told the FTC that this demand would kill the deal. Id. Defendants take issue with plaintiffs’ assertion that they demanded a response to their proposed draft consent order within 24 hours. Furthermore, even though Campbell’s August 4 letter rejected defendants’ proposed order, Gulf called Campbell to schedule a meeting for that evening. (Goold Aff. ¶ 38) At that meeting, Morgan asked “Can we work around refinery divestiture?”; he was told that the “you ought to assume the refinery is very important” although “[Campbell] might support an alternative but ‘the message after checking with all four Commissioners was that ‘it[’]s a refinery.’ ” (Goold Aff. ¶¶ 39, 40) Morgan then “asked Mr. Campbell if he would consider divestiture of Gulf’s Philadelphia or Santa Fe Springs refinery. Mr. Campbell said no.” (Morgan Aff. ¶ 31) According to Campbell, divestiture of Lake Charles was “almost our position” and “[i]t would have taken quite a package of refineries otherwise to satisfy our antitrust concern.” (Campbell Dep. 172) Defendants assert that the Gulf Board was caught between the FTC’s intransigence, and the prospect that divestiture of Lake Charles within two years would yield little and would cost Gulf over $1 billion in lost opportunity costs; other alternatives either were as bleak or were unacceptable to the FTC. (Lee Dep. 77-78; Goodman Dep. 200; McAffee Dep. 89-91; Morgan Aff. ¶ 31) Thus, the Board had no choice but to terminate. (Murdy Dep. 155-56) II. Although defendants initially moved to dismiss the contract and fraud claims, they also moved for summary judgment. Given the sheer volume of material before me now, neither party can deny that this motion is more properly one for summary judgment. Summary judgment is appropriate under Fed.R.Civ.P. 56(c) when, viewing the record in the light most favorable to the nonmoving party, see United States v. Diebold, Inc., 369 U.S. 654, 655, 82 S.Ct. 993, 996, 8 L.Ed.2d 176 (1962) (per curiam); Eastway Constr. Corp. v. City of New York, 762 F.2d 243, 239 (2d Cir.1985), cert. denied, 484 U.S. 918, 108 S.Ct. 269, 98 L.Ed.2d 226 (1987), there “is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law.” Fed.R.Civ.P. 56(c). See also Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247, 106 S.Ct. 2505, 2509, 91 L.Ed.2d 202 (1986). To defeat such a motion, the nonmoving party must offer “ ‘concrete evidence from which a reasonable juror could return a verdict in his favor.’ ” Dister v. Continental Group, Inc., 859 F.2d 1108, 1114 (2d Cir.1988) (quoting Anderson, 477 U.S. at 256, 106 S.Ct. at 2514) (emphasis added). See Clements v. County of Nassau, 835 F.2d 1000, 1005 (2d Cir.1987). Rule 56(e) requires entry of summary judgment against a plaintiff who fails to establish any essential element of his case on which at trial he would bear the burden of proof. Celotex Corp. v. Catrett, 477 U.S. 317, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). This is because “[T]his standard mirrors the standard for a directed verdict under the Federal Rule of Civil Procedure 50(a), which is that the trial judge must direct a verdict if, under the governing law, there can be but one reasonable conclusion as to the verdict.” Anderson, 477 U.S. at 250, 106 S.Ct. at 2511. For the common law contract and fraud claims, a federal district court applies the substantive law of the state in which it sits. Erie R.R. v. Tompkins, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188 (1938). Choice of law rules are substantive. Klaxon Co. v. Stentor Elec. Mfg. Co., 313 U.S. 487, 61 S.Ct. 1020, 85 L.Ed. 1477 (1941). The parties’ elephantine briefs do not discuss choice of law. Cf. Greater Continental Corp. v. Schechter, 304 F.Supp. 325, 329-330 (S.D.N.Y.1969), appeal dismissed, 422 F.2d 1100 (2d Cir.1970). Rather, both sides rely mainly on New York law, although they cite cases from Washington to New Hampshire to Georgia. The Merger Agreement, but not the Offer to Purchase, is expressly made subject to Delaware law, see Merger Agreement at § 10.8(iv); several other states — Pennsylvania, home of Gulf, and Oklahoma, Cities’ headquarters— have an interest in this litigation. I need not reach this choice of law question because no conflict among the laws of the interested states has been shown to affect plaintiffs’ claims, which center on the document to which plaintiffs are parties — the Offer to Purchase, not the Merger Agreement. Deep South Pepsi-Cola Bottling Co., Inc. v. Pepsico, Inc., 88 Civ. 6243 (PEL), slip op. at 20 n. 3, 1989 WL 48400 (S.D.N.Y. May 2, 1989); see also Lehman v. Dow Jones & Co., 783 F.2d 285 (2d Cir.1986). However, because the Merger Agreement is subject to Delaware law, plaintiffs’ claim as third-party beneficiaries of the Merger Agreement would seem to be governed by Delaware law; accordingly, I will rely on Delaware law on that issue. A. Contract Claims Faced with a contract — the Offer to Purchase — which, as will shortly become apparent, affords plaintiffs only slight support for their claim of contract breach, plaintiffs would invoke the “best efforts” obligation contained in an agreement they were not parties to — the Merger Agreement. Alternatively, they would use what they claim are ambiguous contract terms in the Offer to Purchase — most particularly its description of the Merger Agreement’s best efforts clause, and its warning of potential antitrust problems which defendants were required to insert so as to comply with U.S. securities laws — as a wedge to insert extrinsic evidence of Gulf’s alleged secret representation to Cities that Gulf was willing to divest any downstream asset, including the Lake Charles refinery. It is a fundamental principle of contract interpretation that, absent ambiguity, the intent of the parties must be determined from their final writing and no parol evidence or extrinsic evidence is admissible. International Klafter Co. v. Continental Casualty Co., 869 F.2d 96, 100 (2d Cir.1989). See also United States Naval Inst. v. Charter Communications, Inc., 875 F.2d 1044, 1048 (2d Cir.1989); Enercomp, Inc. v. McCorhill Publishing, Inc., 873 F.2d 536, 549 (2d Cir.1989). Moreover, both contracts here were completely integrated. The Merger Agreement contains an integration clause which states: This Agreement ... constitutes the entire agreement and supersedes all other prior agreements and understandings, both written and oral, among the parties, or any one of them, with respect to the subject matter hereof. (Merger Agreement at § 10.8) The Offer to Purchase states: No person has been authorized to give any information or make any representation on behalf of the Purchaser or Gulf not contained in this Offer to Purchase or in the Letter of Transmittal and, if given or made, such information or representation must not be relied upon as having been authorized. (Offer to Purchase at § 18) When contracts contain integration clauses as they do here, extrinsic evidence may not be admitted to prove different or additional terms in the contract, although it may be admitted to interpret ambiguous terms of an integrated contract. Proteus Books, Ltd. v. Cherry Lane Music Co., 873 F.2d 502, 509-10 (2d Cir.1989); 4 S. Williston, A Treatise on the Law of Contracts §§ 631 (3d ed. 1957 & Supp.1988); Restatement (Second) of Contracts § 212 (1981). 1. Antitrust Warning in the Offer to Purchase Plaintiffs reason first that extrinsic evidence may be introduced of Gulf’s secret oral promise to divest any downstream assets because § 16(c) of the Offer to Purchase, the contract between Gulf and plaintiffs, is an ambiguous clause. Section 16(c) provides, in pertinent part: [Gulf] expects that a review of the Offer by the FTC ... will focus particularly upon the petroleum refining and marketing operations and markets of Gulf and [Cities]. Gulf believes that the combined petroleum refining and marketing operations of Gulf and [Cities] do not create a likelihood of antitrust challenge such as would prevent the consummation of the Offer. There can be no assurance that a challenge to the Offer on antitrust grounds will not be made, or if such a challenge is made, what the result will be. See Section 15 for certain conditions to the Offer, including conditions with respect to litigation and certain governmental actions. (Offer to Purchase at § 16(c)) As plaintiffs well know from their briefing of the securities claims here, these statements were required by United States securities laws to provide Cities’ shareholders with full disclosure of all material facts which could affect their decision to tender. Certainly, the possibility of antitrust problems that might make the deal illegal is a material fact which must be disclosed. Gulf & Western Ind., Inc. v. Great A & P Tea Co., 476 F.2d 687, 697 (2d Cir.1973) (G & W failed to disclose possible antitrust problems in tender offer for A & P’s stock). This language is descriptive and precatory; it does not create a contractual obligation. The reader is told Gulf “expects” the FTC to scrutinize the transaction, that Gulf “believes” there are no antitrust problems that would prevent consummation, but that there can be “no assurance” that the FTC will not mount an antitrust challenge; and if it does, there can be no assurance what the result will be, including litigation and an injunction barring the merger. Moreover, even if § 16(c) could be viewed as a contractual obligation as opposed to merely a warning mandated by securities laws, it is not ambiguous. To the contrary, it warns clearly that, although Gulf “believ[ed]” any antitrust problem could be cured, there could be “no assurance” that an antitrust challenge would not arise or what the outcome would be if one did. As a further warning, the shareholder is directed by § 16(c) to § 15, which empowered Gulf to terminate if, as §16 forewarned, the FTC sued to enjoin the transaction. Section 15 left to Gulf’s “sole judgment” the determination of whether the FTC, if it did sue, was demanding divestment of a “material” portion of Cities’ assets, although such judgment had to be made in good faith. See pp. 738-40, infra. Section 15 establishes Gulf’s right to terminate if the FTC sues, “regardless of the circumstances giving rise” to such a lawsuit and specifically regardless of whether “any action or inaction by [Gulf]” gave rise to the lawsuit. Section 16 is thus not only not a representation that Gulf would divest certain assets if the FTC so required; rather, it is an unambiguous warning to plaintiffs that, if the FTC sought to enjoin the merger, Gulf could decide not to fight, but rather to terminate the deal. Moreover, Gulf could do that “regardless of the circumstances” surrounding the action, even if Gulf’s own “action or inaction” precipitated the lawsuit. Gilbert v. El Paso Co., 490 A.2d 1050, 1055 (Del.Ch.1984) (“while the result of Burlington’s termination of its December tender offer might appear unfair to those shareholders who tendered their shares in response to the announcement, it cannot be said that they were misled concerning Burlington’s right to do so”). Indeed, even if § 16(c) could be viewed as an ambiguous contract term, § 15 explicitly overrides it by permitting Gulf to terminate “notwithstanding any other provision of the Offer.” “Notwithstanding” means “take[s] precedence over” and thus negates any contrary provision of the Offer to Purchase. King v. Sununu, 126 N.H. 302, 490 A.2d 796, 800 (1985); State v. Lynch, 137 Vt. 607, 409 A.2d 1001, 1004 (1979); State ex rel. Carmean v. Board of Education, 170 Ohio St. 415, 165 N.E.2d 918, 923 (1960). Moreover, to the extent that there is an inconsistency between a general clause like § 16(c) and a specific one like § 15, the specific clause “operate[s] as a modification and pro tanto nullification” of the general clause. 3 Corbin on Contracts, § 547 at 176 (1960 & Supp.1989); Restatement (Second) of Contracts at § 203. Again, and significantly, § 15 states explicitly that Gulfs right to terminate if the FTC sues (or if one of the other enumerated events occurs) exists “regardless of the circumstances giving rise” to such a lawsuit and regardless of whether “any action or inaction by [Gulf]” caused the lawsuit. Section 15 thus not only contemplated that Gulf might decide to terminate the contract if it encountered serious trouble from the FTC; it also gave Gulf the right to do so even if it chose to do nothing to prevent the FTC’s threat to block the merger; even if it chose, for example, not to sell the Lake Charles refinery, so long as that decision, if based on the value of the facility, was taken in good faith. See pp. 738-40, infra. 2. The “Best Efforts” Clause Plaintiffs’ next offer a set of variations on one theme: a right of action under the Merger Agreement’s “best efforts” clause. A “best efforts” clause requires that one work toward the object of the contract “to the extent of [one’s] total capabilities.” Bloor v. Falstaff Brewing Corp., 454 F.Supp. 258, 267 (S.D.N.Y.1978), aff'd, 601 F.2d 609 (2d Cir.1979). Plaintiffs claim that Gulf failed to use its best efforts to negotiate a settlement with the FTC. Because plaintiffs are not parties to the Merger Agreement and the contract to which they are parties, the Offer to Purchase, contains no such “best efforts” clause, plaintiffs’ arguments fail. Plaintiffs claim that § 11 of the Offer to Purchase, which contains a description of the Merger Agreement’s terms including that agreement’s “best efforts” clause, itself constitutes an explicit promise to plaintiffs from Gulf that Gulf would use its “best efforts.” The meaning of a best efforts clause is “properly determined by the court as a question of law from the four corners of the contract.” Foster v. Citrus County Land Bureau, Inc., 133 A.D.2d 665, 666, 519 N.Y.S.2d 836, 837 (2d Dep’t 1987). Section 11 states explicitly that it merely summarizes provisions of the Merger Agreement so as to provide full disclosure of all material facts to shareholders. Thus, it begins: The following is a summary of certain provisions of the Merger Agreement, the full text of which has been filed as an exhibit to the Purchaser’s Schedule 14D-1. See Section 18. Such summary is qualified in its entirety by reference to such terms. Plaintiffs admit that § ll’s description of the Merger Agreement is mandated by securities regulations (Pltf.’s March 1, 1989 Memorandum at 46 n. 20), but question why Gulf chose to include certain provisions of the Merger Agreement while excluding others. I find this argument unpersuasive: Gulf, as it stated, was providing only a “summary” and told shareholders where they could find the complete Merger Agreement. There is no suggestion that Gulf was reciting certain Merger Agreement terms with the intent of making those terms promises to shareholders as well. The relevant portion of § 11 states that [e]ach party has agreed to use its best efforts to cause the Merger to occur. However, there can be no assurance that the Merger will take place, since, as indicated above, it is subject to certain conditions, some of which are beyond the control of Gulf or the Company. Like § 16, § ll’s reference to best efforts is not ambiguous such that extrinsic evidence is necessary. Far from being a promise to use best efforts, § ll’s statement that “there can be no assurance” that the Merger will take place, because of conditions “some of which are beyond” the parties’ control (necessarily meaning that “some” of the factors were within Gulf's control), is absolutely consistent with §§ 15 and 16’s warning that Gulf could choose not to contest an FTC challenge but could simply terminate the deal. Section 11 cannot be read to promise anything. Plaintiffs cite Lodges 743 & 1746, Int’l Ass’n of Machinists v. United Aircraft Corp., 534 F.2d 422 (2d Cir.1975), cert. denied, 429 U.S. 825, 97 S.Ct. 79, 50 L.Ed.2d 87 (1976), for the proposition that when the Offer to Purchase referred to the best efforts clause in the Merger Agreement, such a reference incorporated that clause. That case concerned a strike settlement agreement which stated that strikers would be allowed to return to work “in accordance with their seniority and demonstrated ability pursuant to article VII, § 2 of the [collectively bargained] contract.” 534 F.2d at 431 n. 3. The court held that the settlement agreement incorporated only that term of the collectively bargained agreement, stating that “a reference by the contracting parties to an extraneous writing for a particular purpose makes it part of their agreement only for the purpose specified.” Id. at 441. Here, however, the language of § 11 — both in the introductory statement describing it as a “summary” and in the warning of “no assurances”— makes it quite plain that the description of contract terms from the Merger Agreement was intended solely to provide full disclosure of material facts to shareholders, not to create new contractual rights. See United California Bank v. The Prudential Ins. Co., 140 Ariz. 238, 681 P.2d 390, 412 (Ct.App.1983) (absence of language in contract evidencing intent to incorporate loan application agreement, descriptive nature of reference to loan application, and fact that loan application was not physically attached all support a finding of no incorporation). Alternatively, plaintiffs argue that the Merger Agreement and the Offer to Purchase should be considered a single contract such that plaintiffs could sue under the Merger Agreement’s “best efforts” clause. “Whether a number of promises constitute one contract or more than one is to be determined by inquiring ‘whether the parties assented to all the promises as a single whole, so that there would have been no bargain whatsoever, if any promise or set of promises were struck out.’ ” United States v. Bethlehem Steel Corp., 315 U.S. 289, 298, 62 S.Ct. 581, 587, 86 L.Ed. 855 (1942) (quoting Williston on Contracts at § 863). Both the text and the context of these contracts demonstrate that each agreement was complete unto itself. United States v. Wallace & Wallace Fuel Co., 540 F.Supp. 419, 426 (S.D.N.Y.1982); United California Bank, 681 P.2d at 410; Nau v. Vulcan Rail & Constr. Co., 286 N.Y. 188, 36 N.E.2d 106 (1941). Each contained an integration clause. See Merger Agreement at § 10.8; Offer to Purchase at § 18. As plaintiffs now concede, the Merger Agreement was not physically attached to the Offer to Purchase. (Pltf.’s March 1, 1989 Memorandum at 46 n. 19) The two agreements were part of two separate transactions; the Offer to Purchase was designed to effect the first phase of the $63 a share cash-out offer to the sole benefit of the Cities shareholders, while the Merger Agreement created the mechanism whereby the two companies could merge after the Offer to Purchase was successfully concluded. Nau does not assist plaintiffs. There the court construed a general contractor agreement, a subcontracting agreement, and a joint venture agreement between the two parties as one integrated document because the subcontracting agreement specifically stated that it was subject to the general contractor agreement and that the goods were warranted to conform to the specifications of the municipality, the ultimate client. All three agreements were obviously part of the same transaction and were designed to “effectuate the same purpose”; manufacturing subway turnstiles. 286 N.Y. at 197, 36 N.E.2d 106. Here, there were separate contracts for separate purposes. To the extent that plaintiffs are proposing that all contracts vaguely relating to the same deal should be read together in spite of explicit language to the contrary in those contracts, so that a party to only one of the contracts can willy-nilly enforce provisions of the other contract, that argument has absolutely no support in contract law and certainly gains no support from Nau. Plaintiffs claim, however, that an Oklahoma state judge, construing these very contracts, held that the Merger Agreement and Offer to Purchase constituted one agreement. (February 22, 1985 Tr. at 3) His oral statement, however, did not concern whether shareholders who were parties only to the Offer to Purchase could sue under the Merger Agreement. Rather, he spoke in response to Cities’ argument that it was not bound by language in the Offer to Purchase that does not appear in the Merger Agreement. The judge did not holcjb nor did he suggest, that clauses in the Merger Agreement could be transported inl;o the Offer to Purchase, so that shareholders could enforce them. To the contrary, he held that the claims of two Cities shareholders who were also suing Gulf in jthe Oklahoma action were misjoined because they arose under a contract (the Offer to Purchase) separate from Cities’ contracts with Gulf. Id. at 6. Finally, if and to the extent that Judge Caldwell’s decision does suggest that these two contracts are one, I respectfully disagree for the reasons noted above. Even if § 11 could be deemed a “best efforts” promise to plaintiffs or if the Merger Agreement and the Offer to Purchase could be considered a single contract, this promise is superseded by § 15, which states that “notwithstanding any other provision of the Offer,” Gulf has the complete and unabridged right to terminate regardless of whether its “action or inaction” gave rise to an FTC lawsuit and “regardless of the circumstances.” 3 Corbin on Contracts, § 547 at 176. In Wallace & Wallace Fuel Co., 540 F.Supp. 419, defendants argued that the ambiguity of the best efforts clause similarly invited extrinsic evidence. There, as here, the “best efforts” clause was overridden by another provision of the contract. The court held: No ambiguity is presented in the instant best efforts clause. This clause is not a guarantee and this court will not allow the Wallace parties to introduce extrinsic evidence attempting to prove that the parties really intended to commit the SB A to future 8(a) contracts. 540 F.Supp. at 427. Here too, even assuming that the Offer to Purchase’s description of the Merger Agreement’s “best efforts” clause, followed closely by a complete disclaimer (“no assurances”), constitutes a clear promise by Gulf that it would use its best efforts to effect the merger, or that the contracts, despi
