2. ADJUSTMENT LIMITATIONS. Any Seller change proposal shall include a "not to exceed" price and delivery adjustment, or a "not less than" price and delivery adjustment, as applicable, acceptable to Seller in the event Buyer subsequently orders such change.

4. OPTION ADJUSTMENTS. In addition to other requirements of the "Changes" clause of this contract, each change proposal submitted pursuant to such clause shall include Seller's proposal for adjustment of the prices set forth in the "Options" clause of this contract. If Buyer orders or accepts such change, the contract price and the contract option prices shall be adjusted accordingly.
5. TESTABILITY. Seller submittal of any Class II Engineering Changes shall include the following statement, to which Seller shall be bound: "This change does not affect the testability of this contract item or its components".

7. CHANGE ORDER ACCOUNTING. For every change or series of related changes, Seller shall maintain separate accounts by job order or other suitable accounting procedure of all incurred segregable, direct costs (less allocable credits), of work, both changed, and not changed, allocable to the change. Such accounts shall be maintained until the parties hereto have unconditionally agreed upon an equitable adjustment for such change.
