CHANGE ORDERS --------------------------------------------------------------------------- 4.1 IET INITIATED CHANGES TO IMPROVE SYSTEM'S DESIGN PERFORMANCE. If IET determines that substantial changes or modifications are required to the Final Design to improve the throughput capacity or otherwise improve the performances of System, and such changes are not otherwise required as a consequence of a change in applicable laws and regulations or concealed or unforeseen conditions, IET shall notify ATG of the proposed changes or modifications to System and shall be authorized to make such changes unless ATG objects in writing to the proposed changes or modifications within 10 days after delivery of IET's change notice. This section places no duty or obligation on IET to make changes but merely permits IET to initiate such changes as it deems appropriate. 4.2 ATG REQUESTED CHANGES. Following approval of the Final Design, if ATG desires any changes in the System, the waste to be processed or the services to be performed by IET, ATG shall notify IET by submitting to IET a change order request ( a "Change Order Request"). IET shall have 30 days after receipt of ATG's Change Order Request to accept or reject the proposed changes and modifications. If IET accepts the changes or modifications requested by ATG, IET shall within the 30 day period specified above submit to ATG a proposal for implementation of the changes, which proposal shall reflect any necessary revisions to the Project Schedule and price of the System, and shall submit such proposal for ATG's approval (a change order). The proposal shall state the basis for any revisions in the Project Schedule and the basis for compensation, which shall include cost impacts due to schedule changes with sufficient detail to permit ATG to make a thorough analysis. ATG and IET shall in good faith negotiate acceptable compensations to be paid to IET regarding the proposed changes and modifications. IET shall proceed with - -------------------------------------------------------------------------------- PURCHASE AGREEMENT GASIFICATION/VITRIFICATION SYSTEM Page 11 of 19 EXHIBIT A IET/ATG CONFIDENTIAL - -------------------------------------------------------------------------------- implementing the Change Order Request if the change order is approved in writing by ATG. 4.3 CHANGES IN LAWS OR REGULATIONS. If IET determines that any change or modification to any applicable laws and regulations, which is enacted or revised subsequent to November 10, 1995, requires a change to the Final Design, ATG shall be notified of the proposed changes or modifications to the System necessitated by such change in the law. Such notice shall set forth the change in the applicable law or regulation and a description of the changes to the final design that is needed in order that the System may comply with the newly enacted or amended law. The Purchase Price shall be adjusted to provide IET additional compensation. 4.4 VALIDITY. Any such changes made pursuant to this section shall not invalidate any agreement between the parties. If the changes result in an increase or decrease in the time required for completion of the work, IET shall revise the Project Schedule to reflect the increase or decrease, and submit such revised Project Schedule to ATG for approval. 4.5 ACCEPTANCE. Upon completion of System fabrication and delivery to ATG's site, IET shall certify to ATG that the System conforms in all material respects to the Final Design as agreed to by the parties pursuant to this Agreement and as in effect on the date of delivery. If, at the end of forty-five (45) days from delivery and receipt of such certification ATG shall not have formally rejected the System, the System shall be deemed accepted ("Acceptance") and ATG shall be subject to all of the continuing payment obligations in Article 3 hereof Formal rejection must be in writing and may only be based on Failure of the System to be in material conformity with the Final Design ("Formal Rejection"). Prior to a Formal rejection, ATG must notify IET in writing of the specific nature of the claimed failure or failures of the System to materially conform to the Final Design. IET shall have a period of forty-five (45) days to remediate or agree with ATG to a schedule for remediation or achieving conformity, which agreement will not be unreasonably withheld by ATG. If after twenty (20) days of recertification of the System by IET, ATG shall not have issued a Formal Rejection, the System shall be deemed Accepted. If the System is Formally Rejected, ATG shall cause the System to be delivered to IET at its premises and ATG shall have no further rights with respect to the System except for its Intellectual Property rights set out in Article 2 hereof. - -------------------------------------------------------------------------------- PURCHASE AGREEMENT GASIFICATION/VITRIFICATION SYSTEM Page 12 of 19 EXHIBIT A IET/ATG CONFIDENTIAL - -------------------------------------------------------------------------------- --------------------------------------------------------------------------- 5.
