[ ] (c) The accountant's statement or other exhibit required by Rule 12b-25(c)
        has been attached if applicable.


Part III - Narrative


     State below in reasonable detail the reasons why Form 10-K and Form 10-KSB,
20-F, 11-K, 10-Q and Form 10-QSB, N-SAR or the transition report or portion
thereof could not be filed within the prescribed time period. (Attach extra
sheets if needed)

     On May 28, 1999, American Xtal Technology, Inc. entered into definitive
agreements to acquire Lyte Optronics, Inc. In connection with the foregoing
transaction, the Company has been required to combine its current and past
financial results with that of Lyte Optronics'. In addition, Lyte Optronics'
Chief Financial Officer and one of its key accounting consultants, are no longer
employed with the Company. Accordingly, new management and accounting staff are
in the process of reconstructing certain financial information to complete the
required quarterly review and Form 10-Q filing. Because of the above, the Form
10-Q cannot be filed by August 15, 1999 without unreasonable effort and / or
expense.
