"The Company hereby appoints the Agent and the Agent agrees to act as an agent of the Company upon the terms and conditions contained in this Agreement."
"The Company shall pay Commission to the Agent for Investment Business which he obtains in accordance with this Agreement. Commission shall be calculated at the rates and in accordance with the provisions contained in the Commission Schedule."
"(f) Subject as provided in sub-clauses 10(g) and 10(h) following termination of this Agreement no sums (and without prejudice to the generality of the foregoing no Commission other than Commission to which entitlement shall have arisen pursuant to the Commission Schedule) which shall not at the date of such termination have become due and payable shall be payable to [the agent]. (g) If at the date of termination of this Agreement ... the Agent has for a period of not less than five years been continuously an Agent of the Company and either (i) within the period of one year after the date of such termination the Agent does not become an Independent Intermediary or become employed by or represent or become an Appointed Representative of any Company or organisation which may directly or indirectly be in competition with the Company; or
"Entitlement to Commission in respect of an Investment Agreement submitted by the Agent shall arise upon receipt by the Company of any appropriate payment ..."
"Entitlement to Commission in respect of an Investment Agreement shall cease to arise in the following circumstances:- (i) upon termination of this Agreement (subject to any rights to Commission under clauses 10(g) and 10(h))"
"... agrees in certain specified circumstances to relax the general rule that once the agent ceases to work for [the Company], he is no longer entitled to commission in respect of [the Company's] clients who were serviced by the agent prior to the termination of his agency. By competing in breach of clause 10(g), the agent is not losing something to which he would otherwise be entitled; rather, by not competing for one year (or by retiring) he is gaining something to which he would not otherwise be entitled.
"... whatever test be applied the answer must, their Lordships think, be the same in this case. It is inconceivable that any petrol company would grant a deal a lease at a nominal rent of a site on which it had spent a substantial sum in installing pumps and other equipment without imposing on the dealer any obligation to buy petrol from it or even to carry on the business of a petrol station on the demised premises. Clauses 3 (g), (h) and (i) [those were the tie] were the heart and soul of the underlease."
"The contract is of course changed by the excision of the tie, and obviously Total would not have granted a lease-back which did not contain such a tie. But I do not think that is good enough to prevent severance and lead to the conclusion that the whole of the lease and lease- back is void. A mortgage to a petrol company containing a tie would, in my judgment, remain in all other respects valid despite the invalidity of the tie as an unreasonable restraint of trade, although the petrol company would not have contemplated making any advance on mortgage to a dealer without a tie."
"... in substance the consideration for the payment of Renewal Commission is not the acceptance by Mr. Marshall of the proviso, but his services in procuring business before his resignation ... Mr Marshall would have been entitled to receive Renewal Commission had he continued to act as [the company's] agent, and in that event it would have been perfectly clear that his provision of his services was the consideration by which that commission was earned. If after the termination of his agency he had complied with proviso (i) of Clause 10(g), he would have continued to be entitled to receive Renewal Commission. Yet it does not seem to me, on this hypothesis, that the change in Mr Marshall's situation would mean that his entitlement to commission was no longer earned by his procuring of business, but must from the moment of termination be treated as the consideration for something else. The reality is that Clause 10(g) simply introduces new conditions, operative from the termination of the agency, to the Agent's right [to] be paid Renewal Commission by reason of the business which he has introduced."
