of March 17, 2004, by and between Superconductor Technologies Inc. (the

1. DESCRIPTION OF EXISTING INDEBTEDNESS: Among other indebtedness which may be
owing by Seller to Buyer, Seller is indebted to Buyer pursuant to, among other
documents, an Accounts Receivable Purchase Agreement, dated March 28, 2003 by
and between Seller and Buyer, as may be amended from time to time (the “Accounts
Receivable Purchase Agreement”). Capitalized terms used without definition

2. DESCRIPTION OF COLLATERAL. The Collateral as described in the Accounts
Receivable Purchase Agreement and the Intellectual Property Security Agreement,

Hereinafter, the above-described security documents and guaranties, together
with all other documents securing repayment of the Indebtedness shall be
referred to as the “Security Documents”. Hereinafter, the Security Documents,
together with all other documents evidencing or securing the Indebtedness shall
be referred to as the “Existing Documents”.

3. DESCRIPTION OF CHANGE IN TERMS.

  A.   Modification(s) to Accounts Receivable Purchase Agreement:

  1.   Item “(g)” under Section 3 entitled “Covenants and Warranties” is hereby

4. CONSISTENT CHANGES. The Existing Documents are each hereby amended wherever
necessary to reflect the changes described above.

5. NO DEFENSES OF SELLER. Seller agrees that, as of this date, it has no
defenses against the obligations to pay any amounts under the Indebtedness.

6. CONTINUING VALIDITY. Seller understands and agrees that in modifying the
existing Indebtedness, Buyer is relying upon Seller’s representations,
warranties, and agreements, as set forth in the Existing Documents. Except as
expressly modified pursuant to this Accounts Receivable Purchase Modification
Agreement, the terms of the Existing Documents remain unchanged and in full
force and effect. Buyer’s agreement to modifications to the existing
Indebtedness pursuant to this Accounts Receivable Purchase Modification
Agreement in no way shall obligate Buyer to make any future modifications to the
Indebtedness. Nothing in this Accounts Receivable Purchase Modification
Agreement shall constitute a satisfaction of the Indebtedness. It is the
intention of Buyer and Seller to retain as liable parties all makers and
endorsers of Existing Documents, unless the party is expressly released by Buyer
in writing. No maker, endorser, or guarantor will be released by virtue of this
Accounts Receivable Purchase Modification Agreement. The terms of this paragraph
apply not only to this Accounts Receivable Purchase Modification Agreement, but
also to any subsequent Accounts Receivable Purchase modification agreements.

7. COUNTERSIGNATURE. This Accounts Receivable Purchase Modification Agreement
shall become effective only when executed by Seller and Buyer.
