if the following pre-conditions were satisfied that (i) all applicable waiting periods under the Hart-Scott Rodino Antitrust Improvement Act, 1976 and the regulations thereunder expiring, lapsing or otherwise terminating; and (ii) the European Commission issuing a decision declaring the merger to be compatible with the common market, and that if EEC or the FTC refused to grant the regulatory approvals the offer would lapse. On receipt of the requisite approvals from the concerned authorities, Appellant No. 1, posted the first formal letter of offer to the shareholders of Burmah Castrol Plc on 8.6.2000. The offer so made was subject to certain conditions which included (i) the condition that the Appellant would be bound by the offer only if valid acceptance was received from not less than 90% of share holders of Burmah Castrol Plc, unless such requirement is waived by the Appellant (the Acceptance Condition) and (ii) no material adverse change having occurred in the business, assets, financial or trading position or profits of any member of the Burmah Castrol Group taking as a whole (the Material Adverse Change Condition). On 7.7.2000, upon receipt of acceptance from more than 50 percent of the share holders of Burmah Castrol Plc, Appellant No.1 waived the Acceptance Condition, the Material Adverse Change Condition and all other conditions and declared the offer wholly unconditional. As a result of the said acquisition of the shares of Burmah Castrol Plc, it became a subsidiary of the Appellant and consequently Appellant No.1 gained control of all the subsidiaries of Burmah Castrol Plc, including Castrol (India) Ltd. In that context, on 10.7.2000, Appellant No.1 approached the Respondent, seeking exemption from the requirement of making a public offer for acquisition of upto 20% of the shares of Castrol India Ltd as required under the Securities and Exchange of India (Substantial Acquisition of Shares and Takeovers) Regulations, 1997 (the Regulations). The said exemption application was disposed of by the Respondent vide order dated 7.8.2000, by granting exemption subject to certain conditions which was not acceptable to the Appellant. The Appellant withdrew on 6.12.2000 its request for exemption and proceeded to take steps to make public offer to the share holders of Castrol (India) Ltd, as required under the Regulations, and for that purpose, a draft text of the public announcement was filed with the Respondent on 6.12.2000, wherein the offer price was shown as Rs. 311.91 calculated by taking 7.7.2000 as the relevant date. The Appellant did not receive immediately any comments on the draft text of the announcement, from the Respondent. On 11.12.2000 the Appellants made a public announcement for acquiring 20% of the equity share capital of Castrol (India) Ltd, at a price of Rs. 311.91 per share. On 10.1.2001 the Appellants received a letter from the Respondent asking them not to proceed with the dispatch of the letter of offer and also to await its comments. Thereafter the matter was discussed between the parties. In the absence of any consensus, the Respondent by its communication dated 16.2.2001 inter alia directed the Appellants to revise the minimum offer price taking 14.3.2000 as the relevant date and also to correspondingly increase the deposit in the escrow account.
