(f) All of the individuals named in the above tables are citizens of the United States of America. Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Item 3 is hereby amended and supplemented to include the following additional information: Elmwood purchased a total of 102,250 shares of Series B Preferred Stock and the Warrant on February 27, 2001 for an aggregate purchase price of $1,000,000 in cash. On February 20, 2001, Elmwood borrowed the funds to purchase the Series B Preferred Stock from The Huntington National Bank. This loan is not secured by any of the assets of Elmwood and bears interest at LIBOR plus 1.85% per year (LIBOR initially being 5.58% per year), which may fluctuate daily. This loan shall mature on April 5, 2004. This loan was unconditionally and fully guaranteed by Kindt-Collins. Item 4. PURPOSE OF TRANSACTION. Item 4 is hereby amended to include the following additional information: Mr. Lindseth, as a co-Managing Partner of Elmwood, directed the separate purchase by Elmwood of 102,250 shares of Series B Preferred Stock and the Warrant for investment purposes. Kindt-Collins, Mr. Lindseth, the Trust, Elmwood, Battery Partners and AER Partners own their respective AER Energy securities for investment purposes. Mr. Lindseth, on behalf of himself, as the Trustee or as Managing Partner of AER Partners, Elmwood or Battery Partners, may seek for investment purposes to purchase additional shares of Common Stock or other series of preferred stock of AER Energy in the open market or in privately negotiated transactions. Additionally, the number of shares of AER Common Stock deemed to be beneficially owned by Mr. Lindseth, the Trustee and Elmwood due to the conversion features of the shares of Series A Preferred Stock and Series B Preferred Stock may automatically change from time to time without any action on the part of such persons due to (i) fluctuations in the amount of accrued and unpaid dividends with respect to the Series A Preferred Stock Page 19 of 35 20 and the Series B Preferred Stock, which dividends may be converted into Common Stock at the same conversion rate as the shares of stock upon which such dividends accrued and (ii) the effect of certain anti-dilution and other terms of such securities upon the conversion rate set forth therein. In addition, the warrants purchased with such securities also contain exercise price adjustment and anti-dilution provisions, which may cause the aggregate number of shares of AER Common Stock that may be received upon the exercise in full of such warrants to be adjusted. Joseph D. Sullivan, on behalf of himself or certain Sullivan family partnerships and trusts, may seek for investment purposes to purchase additional shares of Common Stock in the open market or in privately negotiated transactions. Item 5. INTEREST IN SECURITIES OF THE ISSUER. Item 5 is hereby amended in its entirety to read as follows: The percentages set forth below are based on 24,850,263 shares of Common Stock outstanding as of the close of business on November 9, 2000 (as reported in AER Energy's most recent Form 10-Q), plus, pursuant to Rule 13d-3(d)(1)(i), such additional number of shares that each person may acquire within 60 days pursuant to the exercise of any option, warrant or right, the conversion of any security or the power to revoke a trust or similar arrangement. (a) Kindt-Collins beneficially owns directly 212,994 shares of the Common Stock, or 0.9% of the outstanding Common Stock, of which 112,994 shares may be acquired pursuant to the exercise in full of a warrant that is immediately exercisable. AER Partners beneficially owns directly 3,189,915 shares of Common Stock, or 12.8% of the outstanding Common Stock.

Elmwood beneficially owns 202,250 shares of Series A Preferred Stock, or 50.0% of the outstanding Series A Preferred Stock. Elmwood also beneficially owns 102,250 shares of Series B Preferred Stock, or 100.0% of the outstanding Series B Preferred Stock.

The Trust beneficially owns indirectly, through its interests in AER Partners, Elmwood and Battery Partners, 12,244,403 shares of Common Stock, or 40.0% of the outstanding Common Stock. As discussed above, Mr. Lindseth claims beneficial ownership of all such shares indirectly owned by the Trust. The partnership agreements among the partners of AER Partners, Elmwood and Battery Partners delegate to Mr. Lindseth (individually or as the Trustee), as a co-Managing Partner of each partnership, the authority to vote and decide the disposition of shares of the Common Stock owned by AER Partners and Elmwood; otherwise, Mr. Lindseth (individually and as Trustee) disclaims beneficial ownership of (i) that percentage interest in the Common Stock attributed to the partners of each of AER Energy and Elmwood as set forth in the foregoing tables, other than the Trustee and Virginia M. Lindseth (Mr. Lindseth's spouse) as Trustee under the Virginia M. Lindseth Trust Agreement dated April 25, 1986, as modified (the "VML Trustee") and (ii) that percentage interest in the Common Stock owned indirectly by the partners of Battery Partners (other than the Trustee and the VML Trustee) through their respective ownership interests in Battery Partners. Steven W. Lindseth, Mr. Lindseth's son, is also a co-Managing Partner of AER Partners, Elmwood Partners and Battery Partners. However, as a practical matter Mr. Lindseth acts as Managing Partner and Steven W. Lindseth disclaims beneficial ownership of (i) that percentage interest in the Common Stock attributable to the partners of each of AER Partners and Elmwood Partners other than himself as set forth in the foregoing tables and (ii) that percentage interest in the Common Stock owned indirectly by the partners (other than himself) of Battery Partners through their respective ownership interests in Battery Partners. The following table sets forth the allocation of shares of Common Stock beneficially owned by AER Partners among all of its Page 21 of 35 22 partners. However, except as otherwise provided, nothing contained herein shall be an admission that any of such partners beneficially own such shares of Common Stock.

--------------- (5) The percentages set forth below are based on 24,850,263 shares of Common Stock outstanding as of the close of business on November 9, 2000 (as reported in AER Energy's most recent Form 10-Q), plus, pursuant to Rule 13d-3(d)(1)(i), such additional number of shares that each person may acquire within 60 days pursuant to the exercise of any option, warrant or right, the conversion of any security or the power to revoke a trust or similar arrangement. Mr. Lindseth (individually and as the Trustee), as a co-Managing Partner of each of AER Partners, Elmwood and Battery Partners, and as Chairman of the Board of Kindt-Collins, may be deemed to have beneficial ownership of (i) all the shares of Common Stock owned by each of AER Partners, Elmwood and Kindt-Collins, (ii) all of the shares of Series A Preferred Stock and Series B Preferred Stock owned by Elmwood, (iii) in the case of Mr. Lindseth individually, 30,000 shares of Common Stock owned directly by him and (iv) in the case of Mr. Lindseth both individually and as the Trustee, 121,230 shares of Common Stock owned by Battery Partners, for an aggregate of [A] 12,487,397 shares of Common Stock in the case of Mr. Lindseth and [B] Page 29 of 35 30 12,244,403 shares of Common Stock in the case of the Trustee. Generally, Mr. Lindseth and the Trustee each disclaim beneficial ownership of that percentage interest in the Common Stock, the Series A Preferred Stock and the Series B Preferred Stock attributable to the partners (other than the Trustee and the VML Trustee) of each of AER Partners, Elmwood and Battery Partners as further described above. Similarly, Steven W. Lindseth, Mr. Lindseth's son, as a co-Managing Partner of each of AER Partners and Elmwood, may be deemed to have beneficial ownership of all the shares of Common Stock, Series A Preferred Stock and Series B Preferred Stock owned by each of AER Partners and Elmwood, as well as 121,230 shares of Common Stock owned by Battery Partners and 15,300 shares of common stock that he owns directly, for an aggregate of 12,259,703 shares of Common Stock (or 40.0% of the total shares outstanding). However, as a practical matter, Mr. Lindseth, his father, acts as Managing Partner of such partnerships and Steven W. Lindseth disclaims beneficial ownership of that percentage interest in the Common Stock and Preferred Stock attributable to the partners (other than himself) of AER Partners, Elmwood and Battery Partners as further described above. As a result of the transactions reported in this Amendment No. 7, Mr. Lindseth's total beneficial ownership in AER Energy's Common Stock is now 40.6% of the total shares outstanding and the Trustee's total beneficial ownership in AER Energy's Common Stock is now 40.0% of the total shares outstanding (in each case if all the shares Mr. Lindseth and the Trustee may be deemed to beneficially own are included). Mr. Joseph D. Sullivan owns 299,575 shares of Common Stock directly. Mrs. Sandra H. Sullivan owns 120,000 shares of Common Stock directly. Mr. Joseph D. Sullivan and Mrs. Sandra H. Sullivan each also (i) have an indirect interest through the Waho Fund, a family general partnership, in a percentage of the 52,500 shares of Common Stock owned by such partnership corresponding to their respective ownership interests in such partnership and (ii) have an indirect interest through the Pine Fund Corporation, a corporation wholly owned by Mr. and Mrs. Sullivan, in a percentage interest of the 20,000 shares of Common Stock owned by such corporation corresponding to their respective ownership interests in such corporation. Mr. Leo L. Kovachic owns 1,000 shares of Common Stock directly. Page 30 of 35 31 (b) Kindt-Collins has the sole power to vote and direct the disposition of the 212,994 shares of Common Stock it beneficially owns, and Mr. Lindseth has sole voting and dispositive power with respect to these shares with the other directors of Kindt-Collins listed in Item 2 above. AER Partners, Elmwood and Battery Partners are all managed by Mr. Lindseth (individually and as the Trustee). His son, Mr. Steven A. Lindseth, also has, pursuant to the relevant partnership agreements, the power to vote and direct the disposition of the Common Stock owned by such partnerships (for a total of 12,244,403 shares of the Common Stock), but as a practical matter Mr. Lindseth exercises this power. Mr. Lindseth has sole voting and dispositive power with respect to the 30,000 shares owned by him. Mr. Steven W. Lindseth has sole voting and dispositive control over the 15,300 shares of Common Stock he owns directly. Mr. Joseph D. Sullivan has sole voting and dispositive control over: (i) 299,575 shares of Common Stock he owns directly, (ii) 8,700 shares of Common Stock he holds as Trustee for the Laura S. McKenna Trust dated April 1, 1984, (iii) 10,000 shares he holds as Trustee for the Stephanie D. Sullivan Trust dates May 28, 1986, (v) 52,500 shares of Common Stock owned by the Waho Fund, of which Mr. Sullivan is a general partner (vi) 20,000 shares of Common Stock owned by the Pine Fund Corporation, of which Mr. Sullivan is the President and (vii) 50,000 shares of Common Stock owned by the Sullivan Family Fund, a charitable corporation; for a total of 440,775 shares of Common Stock. Mrs. Sandra H. Sullivan has sole voting and dispositive control over the 120,000 shares of Common Stock she owns directly. Mr. Leo L. Kovachic has sole voting and dispositive power over the 1,000 shares he owns directly. (c) None. (d) Kindt-Collins is a subchapter S corporation and as such, each of its shareholders has the right to receive dividends from, or the proceeds form the sale of, its stock. AER Partners, Elmwood and Battery Partners are each partnerships and as such, each of their respective partners (including the Trustee) has the right to receive distributions from, or Page 31 of 35 32 proceeds from the sale of, any Common Stock owned by such partnership. Such interests of the Trustee relate to more than 5% of the Common Stock. (e) Kindt-Collins ceased to be a beneficial owner of 5% or more of the Common Stock on February 6, 1996, when it sold all but 212,994 of its shares of Common Stock beneficially owned to Elmwood. Item 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. Except as described herein or filed previously with respect to the Schedule 13D, there are no new contracts, arrangements, understandings or relationships with respect to the Common Stock. Item 7.
