Item 5.  Other Events


     On May 1, 1997, SI Diamond Technology, Inc. (the "Company") filed an
Amendment to its Amended and Restated Articles of Incorporation regarding the
Company's Series E Preferred Stock (the "Series E Amendment") with the Secretary
of State of the State of Texas.  The Series E Amendment amended certain terms of
the Company's Series E Preferred Stock ("Series E Preferred"), which amendments
were approved by a vote of the Holders of the Series E Preferred.  All defined
terms relating to the description of amendments to the Series E Preferred shall
have the same meanings as set forth in the amendment to the Series E Preferred,
which are contained in Exhibit 3(I)(1) to this Current Report on Form 8-K and
incorporated by reference herein.



     The terms of the Series E Preferred were amended as follows:

     1.   (a) Each holder of Series E Preferred may convert up to 12% of the
          aggregate shares of Series E Preferred held by such Holder as of April
          21, 1997 at a Conversion Price of $ 0.6429.


          (b) In addition to the 12% of shares which may be converted above,
          each Holder may convert any and all remaining shares of Series E
          Preferred held by such Holder at a Conversion Price equal to $1.50.


     2.   In addition, for each calendar month commencing with April 1997, if
          the average of the Closing Bid Prices of the Company's Common Stock
          for all of the trading days for such calendar month is less than
          $1.00, then the Company shall redeem shares of Series E Preferred held
          by each Holder in an amount equal to the lesser of (1) 7% of the
          aggregate shares of Series E Preferred held by such Holder as of April
          21, 1997, or (2) all shares of Series E Preferred then held by such
          Holder. The redemption price for such shares of Series E Preferred
          Stock to be redeemed with respect to any month pursuant to this
          provision only shall be the Original Series E Issue Price plus the
          accrued Premium. Payment for such redeemed shares of Series E
          Preferred shall be made within ten (10) business days after the last
          day of such calendar month, at the option of the Company, in cash or
          in shares of the Common Stock (valued at the average of the Closing
          Bid Prices of the Company's Common Stock for all trading days for such
          calendar month). Any shares of Common Stock issued pursuant to this
          section shall be included in the Registration Statement which covers
          the shares of Common Stock into which the Series E Preferred are
          convertible.


     On August 4, 1997, the Company filed an Amendment to its Amended and
Restated Articles of Incorporation regarding the Company's Series F Preferred
Stock (the "Series F Amendment") with the Secretary of State of the State of
Texas.  The Series F Amendment amended certain terms of the Company's Series F
Preferred Stock ("Series F Preferred"), which amendments were approved by a vote
of the Holders of the Series F Preferred.  All defined terms relating to the
description of amendments to the Series F Preferred shall have the same meanings
as set forth in the amendment to the Series F Preferred, which are 

 
contained in Exhibit 3(I)(2) to this Current Report on Form 8-K and incorporated
by reference herein.



     The terms of the Series F Preferred were amended as follows:

     1.  The Fixed Conversion Price was lowered from $1.75 to $1.50.

     2.  (a) Each Holder may convert up to 12.5% of the aggregate number of
         shares of Series F Preferred held by such Holder as of July 14, 1997
         during the month of July 1997 and an additional 12.5% of such amount
         during August 1997. These shares shall be converted at the Conversion
         Price as calculated pursuant to the Certificate of Designation, as
         amended herein.


         (b) In addition to the 12.5% that can be converted in July 1997 and the
         12.5% that can be converted in August 1997 at the calculated Conversion
         Price, each Holder of Series F Preferred may convert, at any time, any
         and all remaining shares of Series F Preferred held by such Holder at a
         Conversion Price equal to $1.50.


     3.  In addition, for each calendar month commencing with July 1997, if the
         average of the Closing Bid Prices of the Company's Common Stock for all
         the trading days for such calendar month is less than $1.00, then the
         Holder may require the Company to convert shares of the Series F
         Preferred held by such Holder in an amount equal to the lesser of (1)
         7% of the aggregate shares of Series F Preferred held by such Holder as
         of July 14, 1997 or (2) all shares of Series F Preferred Stock then
         held by such Holder. For shares of Series F Preferred submitted to the
         Company under the terms of this provision, the Company shall have the
         option of redeeming the shares submitted upon notice to the Holders
         within one (1) business day of the receipt of notice from the Holder
         exercising the rights of this provision. If the Company does exercise
         its option to redeem, the redemption price shall be the equivalent of
         115% of the sum of the original Series F Issue Price plus any accrued
         interest under the terms of the Certificate of Designation, as amended.
         If the Company does not exercise its right to redeem under this
         provision, then the shares of Series F Preferred shall be converted
         into shares of the Company's Common Stock (valued at the average of the
         Closing Bid Prices of the Company's Common Stock for all trading days
         for such calendar month). The payment of such redemption price or the
         shares of Common Stock to be received upon conversion pursuant to the
         terms of this provision shall be delivered to the Holder of Series F
         Preferred within ten (10) business days of the receipt by the Company
         of notice from such Holder exercising his rights under the terms of
         this provision. Any shares of Common Stock issued pursuant to these
         provisions shall be included in the Registration Statement which covers
         the shares of Common Stock into which the Series F Preferred are
         convertible.


 
     4.  If the Closing Bid Price of the Corporation's Common Stock does not
         exceed $1.50 by October 12, 1997, the Company agrees to renegotiate the
         conversion terms of the Series F Preferred with its Holders.
