9 There was then further correspondence between the plaintiff's solicitors and the second defendant. On 10 September 1997 the plaintiffs, through their solicitors, wrote to the second defendant. By the letter the plaintiff claimed arrears of rent totalling $83,765 and damages from 1 May 1996 to 30 November 2000 of $931,675.50 less income received from re-renting part of the premises to the Gas Corporation in the sum of $37,732.58 and, if an existing offer to lease was accepted, a further amount of approximately $189,000, leaving a total of damages in the order of $700,000. The letter went on to say that after making further deductions for the possibility of receiving rent for part of the balance of the premises the plaintiffs' claim, for both the arrears of rent and damages from the date the Lease was terminated, would be approximately $760,000. The letter stated that the plaintiff was sympathetic to Barter's position and would look to the second defendant to discharge his obligations under the Lease and take such action as he may think appropriate to recover any contribution from Barter and his estate. At that time the plaintiff knew that Barter was gravely ill and had ceased work in May 1996. Barter passed away in September 1998. On 16 September 1997 the second defendant informed the plaintiff's solicitors that he did not recognise any obligation to pay damages.
