Item 8.01.           Other Events
                     ------------

     At a special meeting of the Management Committee of Technology Funding
Venture Partners IV, An Aggressive Growth Fund, L.P., (the "Partnership")
held on December 15, 2004, the Management Committee voted unanimously to
rescind the resolution approved at the regular quarterly meeting of the
Management Committee in September 2004 directing the Managing General
Partners of the Partnership to proceed with the sale or other disposition
of all of the remaining assets of the Partnership and terminate the
Partnership.

     Noting that facts and circumstances have changed significantly since
September, the Management Committee concluded that liquidating the
remaining assets prematurely would be a mistake and voted unanimously to
continue to operate as usual in order to maximize the value of its
remaining assets for the benefit of the Limited Partners.

The Partnership incorporates by reference the documents listed below:
  The Partnership's 2003 annual report on Form 10-K, filed on March 17,
     2004, file number 814-00055.
  The Partnership's quarterly reports on Form 10-Q, as amended, for the
     periods ending March 31, 2004, and June 30, 2004, respectively,
     filed on August 27, 2004, and for the period ending September 30, 2004,
     filed on November 22, 2004, file number 814-00055.
  The Partnership's Amended and Restated Limited Partnership Agreement
     filed on January 8, 2003, on Form 8-K.
