The following is a list of additional engineering development work that is required before the product is ready for mass production. The man hours column is the estimated number of hours to complete each task.

	TASK	PERSON HOURS
1.	Refine design to improve operation and to reduce costs.	160
2.	Build 2 engineering prototypes for tests and evaluation.	60
3.	Conduct performance and reliability tests on the engineering prototypes.	60
	Note: The performance and reliability tests will be conducted over a period of approximately 2 to 3 weeks.
4.	Modify design and repeat performance tests as required.	40
5.	Prepare formal engineering drawings, design packaging and establishprojected manufacturing costs.	250

Special engineering test equipment will be required to conduct performance and reliability tests. The test equipment will consist of special light-sensing and measuring equipment and controlled light sources. There are no major or critical risks that are anticipated to be able to successfully complete the engineering development.

The technical feasibility has already been proven on the engineering prototype. The balance of the engineering development program will consist primarily of refining the design to optimize the performance and reliability and to reduce manufacturing costs. No other special facilities except the special test equipment mentioned above will be required to complete the development.

A technician will be required to assist Mr. K.V.Menon with the engineering development.
