Please explain...not really sure if this action would be ethical. Please explain base on knowledge. Thank you.

Aaron McKinney is a cost accountant for Majik Systems Inc. Martin Dodd, Vice President of Marketing, has asked Aaron to meet with representatives of Majik Systems' major competitor to discuss product cost data. Martin indicates that the sharing of this data will enable Majik Systems to determine a fair and equitable price for its products.

Would it be ethical for Aaron to attend the meeting and share the relevant cost data? Is Marin in a position to ask this of Aaron? What should Aaron do?
