ITEM 5. OTHER EVENTS

        On May 21, 2001, Sheldahl, Inc., a Minnesota corporation ("Sheldahl" or
the "Company"), announced that it was actively pursuing opportunities to sell a
portion of its technical materials business based in Northfield, Minnesota. The
sale would include the Company's vacuum deposited materials, unidirectional tape
and specialty laminates, including Copper/PET and Copper/PEN used in the
electronics industries (the "Materials Business"). The Company has
entered into a letter agreement (the "Letter Agreement") with Ampersand IV
Limited Partnership, Ampersand IV Companion Fund Limited Partnership
(collectively, "Ampersand") and Morgenthaler Venture Partners V, L.P.
("Morgenthaler" and, collectively with Ampersand, the "Investors") pursuant to
which the Investors agreed to immediately undertake an evaluation of the
possible acquisition by the Investors of the Materials Business. Contemporaneous
with the execution of the Letter Agreement, the Investors and Molex Incorporated
("Molex") extended $5,000,000 in financing to the Company, on the
terms described below.

Letter Agreement

        Under the terms of the Letter Agreement, the Company and the Investors
have agreed to proceed in good faith to negotiate a possible sale of the
Materials Business. Any consummation of the purchase of the assets of the
Materials Business is conditioned on agreement on price, and is subject to the
finalization of a definitive acquisition agreement, the satisfactory completion
of a due diligence investigation of Sheldahl's Material Business and the
completion of a debt financing in the form of term debt and a revolver in favor
of the Investors to fund a portion of the purchase price of the Materials
Business, transaction costs and working capital.

        The Investors and the Company have agreed that until July 22, 2001 (the
"Non-Exclusive Period"), the Company is free to engage in discussions with,
solicit or consider proposals from, and enter into non-exclusive letters of
intent or agreements with any party regarding acquisition and investment with
respect to Materials Business assets. The Company may also provide information
to such parties in connection with their due diligence investigation.

        If Sheldahl desires to enter into an exclusive relationship with a third
party during the Non-Exclusive Period, Sheldahl may do so provided it pays the
Investors' expenses related to the pursuit of a transaction, in an amount not to
exceed $300,000 and arranges for the assignment and payment in full of the $5
million loan (described below). Upon consummation of any such agreement Sheldahl
also must pay the Investors a fee of $900,000.



                                       2

        After the Non-Exclusive Period, in the event the Company does not
terminate the Letter Agreement during such Non-Exclusive Period, the Company
then must negotiate exclusively with the Investors for a period of thirty days,
until August 21, 2001.

        The Letter Agreement expires on August 21, 2001 (the "Termination
Date"). In the event the Company terminates the Letter Agreement prior to its
Termination Date, other than as the result of a breach by the Investors of a
material provision of the Letter Agreement, the Company must pay the Investors
$900,000, plus all of its out-of-pocket expenses and legal fees, not to exceed
$300,000, and pay the $5 million loan (described below), subject to the
Investors' and the Company's obligations under a Subordination Agreement with
Wells Fargo Bank Minnesota, N.A.

        Whether or not a transaction is concluded with the Investors, the
Company also must pay the Investors' expenses, not to exceed $300,000, unless
the Investors breach their obligations in the Letter Agreement.

        The Letter Agreement is incorporated herein by reference as Exhibit 10.0
hereto. The foregoing description of the Letter Agreement does not purport to be
complete as is qualified in its entirety by reference to such Exhibit.

Subordinated Secured Notes Purchase Agreement.

        Concurrent with entering into the Letter Agreement, Sheldahl executed a
Subordinated Secured Notes Purchase Agreement (the "Debt Agreement") by and
among Sheldahl, the Investors and Molex. Under the terms of the Debt Agreement,
Morgenthaler, Ampersand and Molex (the "Purchasers") purchased $5,000,000 of 22%
Senior Secured Subordinated Notes (the "Notes") ("the "Debt Investment").

        Under the terms of the Debt Agreement, interest compounds and is payable
quarterly at the rate of 22% per annum. The Notes (and all accrued interest) are
due and payable simultaneously with the repayment in full of all of the
Company's obligations under its current Credit and Security Agreement with Wells
Fargo Bank Minnesota, N.A. or earlier as provided therein. The Notes are secured
by all of the non real property assets of the Company and its subsidiaries. The
Notes are subordinate to the obligations of the Company to Wells Fargo.

        In connection with the execution of the Debt Agreement, the Company
agreed to pay the Purchasers a commitment fee of $500,000, such fee to be
payable at the maturity date of the Notes.

        The Debt Agreement and Form of Note issuable thereunder, are
incorporated herein by reference to Exhibits 4.1 and 4.2 hereto. The foregoing
description of the Debt Agreement and the Notes does not purport to be complete
and is qualified in its entirety by reference to such Exhibits.

Bank Amendment

        In connection with the consummation of the Debt Investment, Wells Fargo
Bank Minnesota, N.A. waived various financial covenant defaults with respect to
the Company's first quarter. The

Ninth Amendment to Credit Agreement, among other things, establishes a new
covenant for the second quarter based on minimum EBITDA, requires agreement on
new financial covenants prior to the end of the second quarter and consents to
the Debt Investment.
