Dear Limited Partner:

We have recently been made aware of an outstanding offer by Peachtree
Partners to purchase limited partnership units in Technology Funding
Venture Partners IV, An Aggressive Growth Fund, L.P. (the "Partnership").
Under the Securities and Exchange Commission's ("SEC's") Release
No. 34-43069, Commission Guidance on Mini-Tender Offers and Limited
Partnership Tender Offers, effective July 31, 2000, the Partnership is
obligated to respond to such offers with a recommendation to the
Limited Partners.

Peachtree Partners is offering $3.25 per $100 Limited Partner unit. As of
March 31, 2004, the Partnership's unaudited fair value was $12 per $100
unit, exclusive of prior distributions of $110 per unit.  The March 31,
2004, valuations filed with the SEC on Form 10-Q reflect what the Management
Committee believes to be appropriate discounts for the illiquidity of many of
the Partnership's investments.  Based on those valuations and current market
conditions, the Independent General Partners neither recommend for or against
the current tender offer.  Pursuant to Regulation 14E, which provides the
basic procedural protections for all tender offers, the Partnership expresses
no opinion and remains neutral toward Peachtree Partners' offer.

The Management Committee does not see any conflict of interest in its
recommendation.  Peachtree Partners is acquiring the units for investment
purposes only and has stated that it does not intend to influence management
of the Partnership.  The business and operations of the Partnership are
expected to continue as they are today regardless of the outcome of the
current offer.

To our knowledge, there have been no third-party valuations or appraisals
of the Partnership's assets, and neither the Partnership nor Peachtree
Partners has retained an independent party to render an opinion on the
fairness of the offer price.

If you have any questions about the tender offer or the Partnership's
recommendation, please contact our Client Services Department at
1-800-821-5323 or via e-mail at clients2@techfunding.com.

Thank you,

Technology Funding
