67 MCC also submits that the distinction between the obligations of MCC Sanjin under the Asset Sale Agreement, and MCC's obligations under the Guarantee Agreement, provides an explanation for the terms used in cl 3(b) of the Guarantee Agreement. Under the Asset Sale Agreement, the obligation of MCC Sanjin is to pay the amount of $80,000,000 without counterclaim or set-off (cl 3.6(b)). By contrast, under the Guarantee Agreement, MCC's obligation is to pay the Guaranteed Obligation allowing for any defence, set-off or counterclaim that MCC WA or MCC Sanjin asserts (cl 2.1(a)(i)). MCC asserts that cl 3(b) of the Guarantee Agreement is intended to cover a situation in which the dispute resolution procedures contained in the Asset Sale Agreement have run their course and the obligation of MCC Sanjin to the Cape Lambert parties has been ascertained (without regard to any counterclaim or set-off by MCC Sanjin), but either MCC Sanjin asserts a set-off or counterclaim of the kind expressly envisaged by cl 2.1(a)(i) of the Guarantee Agreement, or MCC itself asserts that its obligations are subject to set-off or counterclaim under the general law governing the agreement. MCC asserts that in such a circumstance, cl 3(b) would operate to require MCC to pay into an escrow account an amount equal to the amount in dispute - that is, the amount of the relevant set-off or counterclaim. MCC asserts that in this way, cl 3(b) is given a sensible commercial operation which only takes effect after the dispute resolution procedures contained in the Asset Sale Agreement have run their course. MCC further asserts that if cl 3(b) is given the construction for which the Cape Lambert parties contend, any purported demand by those parties, whether unjustified, colorable or tendentious would by reason only of the fact of demand being made, give rise to an immediate obligation on its part to pay $80,000,000 into an escrow account. MCC asserts that it would not be appropriate to attribute to the parties such an uncommercial and impractical intention.
