                          REGISTRATION RIGHTS AGREEMENT

        This REGISTRATION RIGHTS AGREEMENT is made and entered into as of March
___, 2002 between the investor or investors signatory hereto (each an "Investor"
and together the "Investors") and Superconductor Technologies Inc., a Delaware
corporation (the "Company") with reference to the following facts:

        A. Simultaneously with the execution and delivery of this Agreement, the
Investors (excluding Wells Fargo) are purchasing from the Company, pursuant to a
Securities Purchase Agreement dated the date hereof (the "Purchase Agreement"),
up to (i) an aggregate of 3,714,286 shares (the "Shares") of the Company's
common stock, par value $0.001 per share ("Common Stock"), and stock purchase
warrants ("Investor Warrants") to purchase up to 557,143 additional shares of
Common Stock (the "Investor Warrant Shares") (terms not defined herein shall
have the meanings ascribed to them in the Purchase Agreement).

        B. The Company is also issuing to Wells Fargo Securities, LLC, the
placement agent ("Wells Fargo"), a warrant to purchase up to 213,571 shares of
Common Stock (the "Placement Agent Warrant Shares").

        C. The Company desires to grant to the Investors (including Wells Fargo)
the registration rights set forth herein with respect to the Common Stock
purchased pursuant to the Purchase Agreement, the Investor Warrant Shares and
the Placement Agent Warrant Shares (hereinafter referred to as the "Stock" or
"Securities" of the Company). (The Investor Warrant Shares and the Placement
Agent Warrant Shares are sometimes collectively referred to as the "Warrant
Shares").

        NOW, THEREFORE, the parties hereto mutually agree as follows:

        1. Registrable Securities. As used herein the term "Registrable
Security" means the Securities until (i) the Registration Statement has been
declared effective by the Commission, and all Securities have been disposed of
pursuant to the Registration Statement, (ii) all Securities have been sold under
circumstances under which all of the applicable conditions of Rule 144 ("Rule
144") (or any similar provision then in force) under the Securities Act of 1933,
as amended (the "Securities Act") are met, (iii) all Securities have been
otherwise transferred to holders who may trade such Securities without
restriction under the Securities Act, and the Company has delivered a new
certificate or other evidence of ownership for such Securities not bearing a
restrictive legend or (iv) such time as, in the opinion of counsel to the
Company, all Securities may be sold without any time, volume or manner
limitations pursuant to Rule 144(k) (or any similar provision then in effect)
under the Securities Act. The term "Registrable Securities" means any and/or all
of the securities falling within the foregoing definition of a "Registrable
Security." In the event of any merger, reorganization, consolidation,
recapitalization or other change in corporate structure affecting the Common
Stock, such adjustment shall be deemed to be made in the definition of
"Registrable Security" as is appropriate in order to prevent any dilution or
enlargement of the rights granted pursuant to this Agreement.

        2. Restrictions on Transfer. Each Investor acknowledges and understands
that prior to the registration of the Securities as provided herein, the
Securities are "restricted securities" as defined in Rule 144 promulgated under
the Securities Act. Each Investor understands that no disposition or transfer of
the Securities may be made by Investor in the absence of (i) an

<PAGE>

opinion of counsel to the Investor, in form and substance reasonably
satisfactory to the Company, that such transfer may be made without registration
under the Securities Act or (ii) such registration.

        With a view to making available to the Investors the benefits of Rule
144 under the Securities Act or any other similar rule or regulation of the
Commission that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

            (a) comply with the provisions of paragraph (c)(1) of Rule 144; and

            (b) file with the Commission in a timely manner all reports and
other documents required to be filed with the Commission pursuant to Section 13
or 15(d) under the Exchange Act by companies subject to either of such sections,
irrespective of whether the Company is then subject to such reporting
requirements.

        3. Registration Rights With Respect to the Securities.

               3.1 The Company agrees that it will prepare and file with the
Securities and Exchange Commission ("Commission"), within thirty (30) days after
the Closing Date a registration statement (on Form S-3, or other appropriate
registration statement form) under the Securities Act (the "Registration
Statement"), at the sole expense of the Company (except as provided in Section
3.3 hereof), in respect of the Investors, so as to permit a public offering and
resale of the Securities under the Act by the Investors as selling stockholders
and not as underwriters. The Company shall use its best efforts to cause such
Registration Statement to become effective within ninety (90) days from the
Closing Date. The number of shares designated in the Registration Statement to
be registered shall include the Shares and Warrant Shares. The Company will
notify the Investors of the effectiveness of the Registration Statement within
one Trading Day of such event.

               3.2 The Company will maintain the Registration Statement or
post-effective amendment filed under this Section 3 effective under the
Securities Act until the earlier of (i) the date that none of the Securities
covered by such Registration Statement are or may become issued and outstanding,
(ii) the date that all of the Securities have been sold pursuant to such
Registration Statement, (iii) the date the Investors receive an opinion of
counsel to the Company that the Securities may be sold under the provisions of
Rule 144 without limitation as to volume, (iv) all Securities have been
otherwise transferred to persons who may trade such shares without restriction
under the Securities Act, and the Company has delivered a new certificate or
other evidence of ownership for such securities not bearing a restrictive
legend, or (v) all Securities may be sold without any time, volume or manner
limitations pursuant to Rule 144(k) or any similar provision then in effect
under the Securities Act in the opinion of counsel to the Company (the
"Effectiveness Period").

               3.3 All fees, disbursements and out-of-pocket expenses and costs
incurred by the Company in connection with the preparation and filing of the
Registration Statement under subparagraph 3.1 and in complying with applicable
securities and Blue Sky laws (including, without limitation, all attorneys' fees
of the Company) shall be borne by the Company. The Investors shall bear the cost
of underwriting and/or brokerage discounts, fees and commissions, if any,
applicable to the Securities being registered and the fees and expenses of their
counsel. The Investors and their counsel shall have a reasonable period, not to
exceed five (5) trading days, to review the proposed Registration Statement or
any amendment thereto, prior to filing with the Commission, and the Company
shall upon request provide each Investor with copies of any comment letters
received from the Commission with respect thereto within

                                       2
<PAGE>

two (2) trading days of receipt thereof. The Company shall qualify any of the
Securities for sale in such states as any Investor reasonably designates and
shall furnish indemnification in the manner provided in Section 6 hereof.
However, the Company shall not be required to qualify in any state which will
require an escrow or other restriction relating to the Company and/or the
sellers, or which will require the Company to qualify to do business in such
state or require the Company to file therein any general consent to service of
process. The Company at its expense will supply the Investors with copies of the
applicable Registration Statement and the prospectus included therein and other
related documents in such quantities as may be reasonably requested by the
Investors.

               3.4 The Company shall not be required by this Section 3 to
include any Investor's Securities in any Registration Statement which is to be
filed if, in the opinion of counsel to the Company, the proposed offering or
other transfer as to which such registration is requested is exempt from
applicable federal and state securities laws and would result in all Investors
or transferees obtaining securities which are not "restricted securities" as
defined in Rule 144 under the Securities Act.

               3.5 In the event that the Registration Statement to be filed by
the Company pursuant to Section 3.1 above is not declared effective by the
Commission within ninety (90) days from the Closing Date (a "Registration
Default"), then the Company will pay each Investor (excluding Wells Fargo) as
liquidated damages for such failure and not as a penalty five percent (5%) of
the Purchase Price ("Liquidated Damages Amount"). If the Registration Statement
is not declared effective by the Commission within one hundred twenty (120) days
of Closing, then the Company shall pay each Investor (excluding Wells Fargo) a
second Liquidated Damages Amount. Such payment of the liquidated damages shall
be made to the Investors in cash, within five (5) calendar days of demand;
provided, however, that the payment of such liquidated damages shall not relieve
the Company from its obligations to register the Securities pursuant to this
Section. If the Company does not remit the payment to the Investors as set forth
above, the Company will pay the Investors reasonable costs of collection,
including attorneys' fees, in addition to the liquidated damages. The
registration of the Securities pursuant to this provision shall not affect or
limit the Investors' other rights or remedies as set forth in this Agreement.

               3.6 No provision contained herein shall preclude the Company from
selling securities pursuant to any Registration Statement in which it is
required to include Securities pursuant to this Section 3.

               3.7 If at any time or from time to time after the effective date
of any Registration Statement, the Company notifies the Investors in writing of
the existence of a Potential Material Event (as defined in Section 3.8 below),
the Investors shall not offer or sell any Securities or engage in any other
transaction involving or relating to Securities, from the time of the giving of
notice with respect to a Potential Material Event until the Investors receive
written notice from the Company that such Potential Material Event either has
been disclosed to the public or no longer constitutes a Potential Material
Event; provided, however, that the Company may not so suspend the right to such
holders of Securities for more than thirty (30) days in the aggregate (90 days
in the case of an acquisition requiring the filing of audited financial
statements of the acquired business under Form 8-K) during any twelve month
period, during the period the Registration Statement is required to be in
effect. The Company must, if lawful, give the Investors notice in writing at
least two (2) trading days prior to the first day of the blackout period.

                                       3
<PAGE>

               3.8 "Potential Material Event" means any of the following: (a)
the possession by the Company of material information not ripe for disclosure in
a registration statement, as determined in good faith by the Chief Executive
Officer or the Board of Directors of the Company that disclosure of such
information in a Registration Statement would be detrimental to the business and
affairs of the Company; or (b) any material engagement or activity by the
Company which would, in the good faith determination of the Chief Executive
Officer or the Board of Directors of the Company, be adversely affected by
disclosure in a registration statement at such time.

        4. Cooperation with Company. The Investors will cooperate with the
Company in all respects in connection with this Agreement, including timely
supplying all information and confirmations reasonably requested by the Company
or the Commission (which shall include all information regarding the Investors
and proposed manner of sale of the Registrable Securities required to be
disclosed in any Registration Statement) and executing and returning all
documents reasonably requested in connection with the registration and sale of
the Registrable Securities and entering into and performing their obligations
under any underwriting agreement, if the offering is an underwritten offering,
in usual and customary form, with the managing underwriter or underwriters of
such underwritten offering. Nothing in this Agreement shall obligate any
Investor to consent to be named as an underwriter in any Registration Statement.
The obligation of the Company to register the Registrable Securities shall be
absolute and unconditional as to those Securities which the Commission will
permit to be registered without naming the Investors as underwriters. Any delay
or delays caused by the Investors by failure to cooperate as required hereunder
shall not constitute a Registration Default.

        5. Registration Procedures. If and whenever the Company is required by
any of the provisions of this Agreement to effect the registration of any of the
Registrable Securities under the Act, the Company shall (except as otherwise
provided in this Agreement), as expeditiously as possible, subject to the
Investors' assistance and cooperation as reasonably required with respect to
each Registration Statement:

               5.1 (a) prepare and file with the Commission such amendments and
supplements to the Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such registration statement
whenever the Investors shall desire to sell or otherwise dispose of the same
(including prospectus supplements with respect to the sales of securities from
time to time in connection with a registration statement pursuant to Rule 415
promulgated under the Securities Act) and (b) take all lawful action such that
each of (A) the Registration Statement and any amendment thereto does not, when
it becomes effective, contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading and (B) the prospectus forming part of the Registration
Statement, and any amendment or supplement thereto, does not at any time during
the Effectiveness Period include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading;

               5.2 (a) prior to the filing with the Commission of any
Registration Statement (including any amendments thereto) and the distribution
or delivery of any prospectus (including any supplements thereto), provide draft
copies thereof to the Investors as required by Section 3.3 and reflect in such
documents all such comments as the Investors (and their counsel) reasonably may
propose respecting the Selling Shareholders and Plan of Distribution

                                       4
<PAGE>

sections (or equivalents) and (b) furnish to each Investor such numbers of
copies of a prospectus including a preliminary prospectus or any amendment or
supplement to any prospectus, as applicable, in conformity with the requirements
of the Act, and such other documents, as such Investor may reasonably request in
order to facilitate the public sale or other disposition of the securities owned
by such Investor;

               5.3 register and qualify the Registrable Securities covered by
the Registration Statement under such other securities or blue sky laws of such
jurisdictions as the Investors shall reasonably request (subject to the
limitations set forth in Section 3.3 above), and do any and all other acts and
things which may be necessary or advisable to enable each Investor to consummate
the public sale or other disposition in such jurisdiction of the securities
owned by such Investor;

               5.4 list such Registrable Securities on the Principal Market, if
the listing of such Registrable Securities is then permitted under the rules of
such Principal Market;

               5.5 notify each Investor at any time when a prospectus relating
thereto covered by the Registration Statement is required to be delivered under
the Securities Act, of the happening of any event of which it has knowledge as a
result of which the prospectus included in the Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing, and the
Company shall use its best efforts to prepare and file a curative amendment
under Section 5.1;

               5.6 as promptly as practicable after becoming aware of such
event, notify each Investor who holds Registrable Securities being sold (or, in
the event of an underwritten offering, the managing underwriters) of the
issuance by the Commission of any stop order or other suspension of the
effectiveness of the Registration Statement at the earliest possible time and
take all lawful action to effect the withdrawal, recession or removal of such
stop order or other suspension;

               5.7 cooperate with the Investors to facilitate the timely
preparation and delivery of certificates for the Registrable Securities to be
offered pursuant to the Registration Statement and enable such certificates for
the Registrable Securities to be in such denominations or amounts, as the case
may be, as the Investors reasonably may request and registered in such names as
the Investors may request; and, within five (5) trading days after a
Registration Statement which includes Registrable Securities is declared
effective by the Commission, deliver and cause legal counsel selected by the
Company to deliver to the transfer agent for the Registrable Securities (with
copies to the Investors) an appropriate instruction and, to the extent
necessary, an opinion of such counsel;

               5.8 take all such other lawful actions reasonably necessary to
expedite and facilitate the disposition by the Investors of their Registrable
Securities in accordance with the intended methods therefor provided in the
prospectus which are customary for issuers to perform under the circumstances;

               5.9 in the event of an underwritten offering, promptly include or
incorporate in a prospectus supplement or post-effective amendment to the
Registration Statement such information as the managers reasonably agree should
be included therein and to which the Company does not reasonably object and make
all required filings of such prospectus supplement or post-effective amendment
as soon as practicable after it is notified of the matters to be included or
incorporated in such Prospectus supplement or post-effective amendment; and

                                       5
<PAGE>

               5.10 maintain a transfer agent and registrar for its Common
Stock.

        6. Indemnification.

               6.1 To the maximum extent permitted by law, the Company agrees to
indemnify and hold harmless the Investors and each person, if any, who controls
an Investor within the meaning of the Securities Act (each a "Distributing
Investor") against any losses, claims, damages or liabilities, joint or several
(which shall, for all purposes of this Agreement, include, but not be limited
to, all reasonable costs of defense and investigation and all reasonable
attorneys' fees and expenses), to which the Distributing Investor may become
subject, under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, or any related final prospectus or
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading; provided,
however, that the Company will not be liable in any such case to the extent, and
only to the extent, that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such Registration Statement, preliminary prospectus,
final prospectus or amendment or supplement thereto in reliance upon, and in
conformity with, written information furnished to the Company by the
Distributing Investor, its counsel, affiliates or any underwriter, specifically
for use in the preparation thereof. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

               6.2 To the maximum extent permitted by law, each Distributing
Investor agrees that it will indemnify and hold harmless the Company, and each
officer and director of the Company or person, if any, who controls the Company
within the meaning of the Securities Act, against any losses, claims, damages or
liabilities (which shall, for all purposes of this Agreement, include, but not
be limited to, all reasonable costs of defense and investigation and all
reasonable attorneys' fees and expenses) to which the Company or any such
officer, director or controlling person may become subject under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in any Registration
Statement, or any related final prospectus or amendment or supplement thereto,
or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, but in each case only to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in such Registration Statement, final prospectus or amendment or supplement
thereto in reliance upon, and in conformity with, written information furnished
to the Company by such Distributing Investor, its counsel, affiliates or any
underwriter, specifically for use in the preparation thereof. This indemnity
agreement will be in addition to any liability which the Distributing Investor
may otherwise have.

               6.3 Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action against such indemnified
party, such indemnified party will, if a claim in respect thereof is to be made
against the indemnifying party under this Section 6, notify the indemnifying
party in writing of the commencement thereof; but the omission to so notify the
indemnifying party will not relieve the indemnifying party from any liability
which it may have to any indemnified party except to the extent the failure of
the indemnified party to provide such written notification actually prejudices
the ability of the indemnifying party to defend such action. In case any such
action is brought against any indemnified party, and it notifies the

                                       6
<PAGE>

indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate in, and, to the extent that it may wish, jointly with
any other indemnifying party similarly notified, assume the defense thereof,
subject to the provisions herein stated and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party
under this Section 6 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than
reasonable costs of investigation, unless the indemnifying party shall not
pursue the action to its final conclusion. The indemnified parties as a group
shall have the right to employ one separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the indemnifying party if the indemnifying party
has assumed the defense of the action with counsel reasonably satisfactory to
the indemnified party unless (i) the employment of such counsel has been
specifically authorized in writing by the indemnifying party, or (ii) the named
parties to any such action (including any impleaded parties) include both the
indemnified party and the indemnifying party and the indemnified party shall
have been advised by its counsel that there may be one or more legal defenses
available to the indemnifying party different from or in conflict with any legal
defenses which may be available to the indemnified party or any other
indemnified party (in which case the indemnifying party shall not have the right
to assume the defense of such action on behalf of such indemnified party, it
being understood, however, that the indemnifying party shall, in connection with
any one such action or separate but substantially similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances, be liable only for the reasonable fees and expenses of one
separate firm of attorneys for the indemnified party, which firm shall be
designated in writing by the indemnified party). No settlement of any action
against an indemnified party shall be made without the prior written consent of
the indemnified party, which consent shall not be unreasonably withheld so long
as such settlement includes a full release of claims against the indemnified
party.

        7. Contribution. In order to provide for just and equitable contribution
under the Securities Act in any case in which (i) the indemnified party makes a
claim for indemnification pursuant to Section 6 hereof but is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified party, then the Company and the
applicable Distributing Investor shall contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (which shall, for
all purposes of this Agreement, include, but not be limited to, all reasonable
costs of defense and investigation and all reasonable attorneys' fees and
expenses), in either such case (after contribution from others) on the basis of
relative fault as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the applicable Distributing Investor on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Distributing Investor agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to in this Section 7. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section 7
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any

                                       7
<PAGE>

such action or claim. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

        Notwithstanding any other provision of this Section 7, in no event shall
any (i) Investor be required to undertake liability to any person under this
Section 7 for any amounts in excess of the dollar amount of the proceeds
received by such Investor from the sale of such Investor's Registrable
Securities (after deducting any fees, discounts and commissions applicable
thereto) pursuant to any Registration Statement under which such Registrable
Securities are registered under the Securities Act.

        8. Notices. All notices, demands, requests, consents, approvals, and
other communications required or permitted hereunder shall be in writing and,
unless otherwise specified herein, shall be (i) hand delivered, (ii) deposited
in the mail, registered or certified, return receipt requested, postage prepaid,
(iii) delivered by reputable air courier service with charges prepaid, or (iv)
transmitted by facsimile, addressed as set forth in the Purchase Agreement or to
such other address as such party shall have specified most recently by written
notice. Any notice or other communication required or permitted to be given
hereunder shall be deemed effective (a) upon hand delivery or delivery by
facsimile, with accurate confirmation generated by the transmitting facsimile
machine, at the address or number designated in the Purchase Agreement (if
delivered on a business day during normal business hours where such notice is to
be received), or the first business day following such delivery (if delivered
other than on a business day during normal business hours where such notice is
to be received) or (b) on the first business day following the date of sending
by reputable courier service, fully prepaid, addressed to such address, or (c)
upon actual receipt of such mailing, if mailed. Either party hereto may from
time to time change its address or facsimile number for notices under this
Section 8 by giving at least ten (10) days' prior written notice of such changed
address or facsimile number to the other party hereto.

        9. Assignment. This Agreement is binding upon and inures to the benefit
of the parties hereto and their respective heirs, successors and permitted
assigns. The rights granted the Investors under this Agreement may be assigned
to any purchaser of substantially all of the Registrable Securities (or the
rights thereto) from an Investor, as otherwise permitted by the Purchase
Agreement.

        10. Determinations. Except as otherwise expressly provided herein, all
consents, approvals and other determinations (other than amendments to the terms
and provisions of this Agreement) to be made by the Investors pursuant to this
Agreement and all waivers and amendments to or of any provisions in this
Agreement after the Closing Date shall be made by Investors (excluding Investors
who are affiliates of the Company) that have invested more than fifty percent
(50%) of the aggregate Investment Amounts invested by all Investors (excluding
Investors who are affiliates of the Company).

        11. Counterparts/Facsimile. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original, but all of which,
when together shall constitute but one and the same instrument, and shall become
effective when one or more counterparts have been signed by each party hereto
and delivered to the other parties. In lieu of the original, a facsimile
transmission or copy of the original shall be as effective and enforceable as
the original.

        12. Remedies. The remedies provided in this Agreement are cumulative and
not exclusive of any remedies provided by law. If any term, provision, covenant
or restriction of this

                                       8
<PAGE>

Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated, and the parties hereto shall use
their best efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision,
covenant or restriction.

        13. Conflicting Agreements. The Company shall not enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the holders of Registrable Securities in this Agreement or otherwise
prevents the Company from complying with all of its obligations hereunder.

        14. Headings. The headings in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement.

        15. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to agreements made
and to be performed in the State of Delaware (without regard to principles of
conflict of laws). Both parties irrevocably consent to the exclusive
jurisdiction of the United States federal courts and the state courts located in
Delaware with respect to any suit or proceeding based on or arising under this
Agreement, the agreements entered into in connection herewith or the
transactions contemplated hereby or thereby and irrevocably agree that all
claims in respect of such suit or proceeding may be determined in such courts.
The Company and each Purchaser irrevocably waives the defense of an inconvenient
forum to the maintenance of such suit or proceeding. The Company and each
Purchaser further agrees that service of process upon a party mailed by first
class mail shall be deemed in every respect effective service of process upon
the party in any such suit or proceeding. Nothing herein shall affect either
party's right to serve process in any other manner permitted by law. Each of the
parties agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.

                               WARRANT TO PURCHASE

                                  ------------
                             SHARES OF COMMON STOCK
                               AS DESCRIBED HEREIN

This certifies that, for value received,____________________________, or its
successors and assigns ("Holder"), is entitled to purchase from Superconductor
Technologies Inc., a Delaware corporation (the "Company"), up to and including
____________ fully paid and non-assessable shares (the "Number of Shares") of
the common stock, par value $0.001 per share, of the Company (the "Common
Stock") on the terms set forth herein at an exercise price of Five Dollars and
Fifty Cents ($5.50) per share (the "Purchase Price"). The Number of Shares and
the Purchase Price may be adjusted from time to time as described in this
Warrant.

        1. Exercise.

               1.1 Time for Exercise. This Warrant may be exercised in whole or
in part at any time, and from time to time, during the period commencing one
hundred eighty-one (181) days from the date of this Warrant and expiring on
March 10, 2007.

               1.2 Manner of Exercise. This Warrant shall be exercised by
delivering it to the Company with the attached exercise form duly completed and
signed, specifying (i) the number of shares as to which the Warrant is being
exercised at that time (the "Exercise Number"), and (ii) cash or a certified
check in an amount equal to the Exercise Number multiplied by the Purchase
Price, and the Holder shall be entitled to receive the full Exercise Number of
shares of Common Stock.

               1.3 Effect of Exercise. Promptly (but in any case within five
business days) after any exercise, the Company shall deliver to the Holder (i)
duly executed certificates in the name or names specified in the exercise notice
representing the aggregate number of shares

<PAGE>

issuable upon such exercise, and (ii) if this Warrant is exercised only in part,
a new Warrant of like tenor representing the balance of the Number of Shares.
Such certificates shall be deemed to have been issued, and the person receiving
them shall be deemed to be a holder of record of such shares, as of the close of
business on the date the actions required in Section 1.2 shall have been
completed or, if on that date the stock transfer books of the Company are
closed, as of the next business day on which the stock transfer books of the
Company are open.

        2. Transfer of Warrants and Stock.

               2.1 Transfer Restrictions. Except as provided in the Registration
Rights Agreement dated the date hereof, the sale or re-sale of the Warrant and
the Common Stock issuable upon exercise of the Warrant has not been and is not
being registered under the Securities Act of 1933, as amended ("Securities
Act"), or any applicable state securities laws. Neither this Warrant nor the
securities issuable upon its exercise may be sold, transferred or pledged unless
the Company shall have been supplied with reasonably satisfactory evidence that
such transfer is not in violation of the Securities Act and any applicable state
securities laws. The Company may place a legend to that effect on this Warrant,
any replacement Warrant and each certificate representing shares issuable upon
exercise of this Warrant.

               2.2 Manner of Transfer. Upon delivery of this Warrant to the
Company with the attached assignment form duly completed and signed, the Company
will promptly (but in any case within five business days) execute and deliver to
each transferee and, if applicable, the Holder, Warrants of like tenor
evidencing the rights (i) of the transferee(s) to purchase the Number of Shares
specified for each in the assignment forms, and (ii) of the Holder to purchase
any untransferred portion, which in the aggregate shall equal the Number of
Shares of the original Warrant. The Company may decline to proceed with any
partial transfer if any new Warrant would represent the right to purchase fewer
than one hundred shares of Common Stock (such number to be adjusted as provided
in Section 4). If this Warrant is properly assigned in compliance with this
Section 2, it may be exercised by an assignee without having a new Warrant
issued.

               2.3 Loss, Destruction of Warrant Certificates. Upon receipt of
(i) evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of any Warrant and (ii) except in the case of
mutilation, an indemnity or security reasonably satisfactory to the Company (the
original Holder's or any other institutional Holder's indemnity agreed to be
satisfactory), the Company will promptly (but in any case within five business
days) execute and deliver a replacement Warrant of like tenor representing the
right to purchase the same Number of Shares.

        3. Cost of Issuances. The Company shall pay all expenses, transfer taxes
and other charges payable in connection with the preparation, issuance and
delivery of stock certificates or replacement Warrants, except for any transfer
tax or other charge imposed as a result of (i) any issuance of stock
certificates in any name other than the name of the Holder upon exercise of the
Warrant or (ii) any transfer of the Warrant. The Company shall not be required
to issue or deliver any stock certificate or Warrant until it receives
reasonably satisfactory evidence that any such tax or other charge has been paid
by the Holder.

        4. Anti-Dilution Provisions. If any of the following events occur at any
time hereafter during the life of this Warrant, then the Purchase Price and the
Number of Shares immediately prior to such event shall be changed as described
in order to prevent dilution:

               4.1 Stock Splits and Reverse Splits. If at any time the
outstanding shares of Common Stock are subdivided into a greater number of
shares, then the Purchase Price will be reduced proportionately and the Number
of Shares will be increased proportionately.

                                       2
<PAGE>

Conversely, if at any time the outstanding shares of Common Stock are
consolidated into a smaller number of shares, then the Purchase Price will be
increased proportionately and the Number of Shares will be reduced
proportionately.

               4.2 Effect of Reorganization and Asset Sales. If any (i)
reorganization or reclassification of the Common Stock, (ii) consolidation or
merger of the Company with or into another corporation, (iii) sale of all or
substantially all of its operating assets to another corporation, or (iv) sale
of the Company substantially as a going concern followed by a liquidation of the
Company (any such occurrence shall be an "Event"), is effected in such a way
that holders of Common Stock are entitled to receive securities and/or assets as
a result of their Common Stock ownership, then upon exercise of this Warrant the
Holder will have the right to receive the shares of stock, securities or assets
which they would have received if such rights had been fully exercised as of the
record date for such Event. The Company will not effect any Event unless prior
to or simultaneously with its consummation the successor corporation resulting
from the consolidation or merger (if other than the Company), or the corporation
purchasing the Company's assets, assumes the performance of the Company's
obligations under this Warrant (as appropriately adjusted to reflect such
consolidation, merger or sale such that the Holder's rights under this Warrant
remain, as nearly as practicable, unchanged) by a binding written instrument.

               4.3 Notices.

                      4.3.1 Notice of Adjustments. When any adjustment is
required to be made under this Section 4, the Company shall promptly (i)
determine such adjustments, (ii) prepare and retain on file a statement
describing in reasonable detail the method used in arriving at the adjustment;
and (iii) cause a copy of such statement, together with any agreement required
by Section 4.2, to be mailed to the Holder within 10 days after the date on
which the circumstances giving rise to such adjustment occurred.

                      4.3.2 Notice of Events. If at any time (i) the Company
declares any dividends on the Common Stock, (ii) any Event is expected to occur,
or (iii) there is a voluntary or involuntary dissolution, liquidation or winding
up of the Company, then the Company shall give the Holder at least thirty (30)
but not more than ninety (90) days written notice of the date on which the books
of the Company will close or upon which a record will be taken with regard to
such occurrence. Such notice will also specify the date as of which the holders
of the Common Stock will participate in the dividend or will be entitled to
exchange their shares for securities or other property. The notice may state
that the record date is subject to the effectiveness of a registration statement
under the Securities Act or to a favorable vote or determination of shareholders
or of any governmental agency.

               4.4 Computations and Adjustments. Upon each computation of an
adjustment under this Section 4, the Purchase Price shall be computed to the
next lowest cent and the Number of Shares shall be calculated to the next
highest whole share. However, the fractional amount shall be used in calculating
any future adjustments. No fractional shares of Common Stock shall be issued in
connection with the exercise of this Warrant, but the Company shall, in the case
of the final exercise under this Warrant, make a cash payment for any fractional
shares based on the closing price on the date of exercise of a share of Common
Stock on the principal exchange or system on which the Common Stock is listed or
traded (the "Principal Exchange") (or, if not then listed or traded thereon, the
mean of the closing bid and asked prices on an automated quotation system, or,
if such quotations are not available, such value (determined without discount
for illiquidity or minority status) as may be determined in good

                                       3
<PAGE>

faith by the Company's Board of Directors, which determination shall be
conclusively binding on the parties). Notwithstanding any changes in the
Purchase Price or the Number of Shares, this Warrant, and any Warrants issued in
replacement or upon transfer thereof, may continue to state the initial Purchase
Price and the initial Number of Shares. Alternatively, the Company may elect to
issue a new Warrant or Warrants of like tenor for the additional shares of
Common Stock purchasable hereunder or, upon surrender of the existing Warrant,
to issue a replacement Warrant evidencing the aggregate Number of Shares to
which the Holder is entitled after such adjustments.

               4.5 Exercise Before Payment Date. In the event that this Warrant
is exercised after the record date for any event requiring an adjustment, but
prior to the actual event, the Company may elect to defer issuing to the Holder
any payment or additional securities required by such adjustment until the
actual event occurs; provided, however, that the Company shall deliver a "due
bill" or other appropriate instrument to the Holder transferable to the same
extent as the Common Stock issuable on exercise evidencing the Holder's right to
receive such additional payment or securities upon the occurrence of the event
requiring such adjustment.

        5. Covenants. The Company agrees that:

               5.1 Reservation of Stock. During the period in which this Warrant
may be exercised, the Company will reserve sufficient authorized but unissued
securities (and, if applicable, property) to enable it to satisfy its
obligations on exercise of this Warrant. If at any time the Company's authorized
securities shall not be sufficient to allow the exercise of this Warrant, the
Company shall take such corporate action as may be necessary to increase its
authorized but unissued securities to be sufficient for such purpose;

               5.2 No Liens, etc. All securities that may be issued upon
exercise of this Warrant will, upon issuance, be validly issued, fully paid,
non-assessable and free from all taxes, liens and charges with respect to the
issue thereof, and shall be listed on any exchanges or authorized for trading on
any automated systems on which that class of securities is listed or authorized
for trading;

               5.3 No Diminution of Value. The Company will not take any action
to terminate this Warrant or to diminish it in value;

               5.4 Furnish Information. The Company will promptly deliver to the
Holder copies of all financial statements, reports, proxy statements and other
information which the Company shall have sent to its shareholders generally; and

               5.5 Stock and Warrant Transfer Books. Except upon dissolution,
liquidation or winding up or for ordinary holidays and weekends, the Company
will not at any time close its stock or warrant transfer books so as to result
in preventing or delaying the exercise or transfer of this Warrant.

        6. Redemption.

               6.1 At any time after the date which is thirty (30) months
following the effective date of the Company's registration statement registering
the Common Stock issuable upon exercise of the Warrants, the Warrants may be
redeemed, at the option of the Company, at $0.10 per Warrant provided the market
price of the Common Stock shall exceed Six Dollars and Eighty-Seven Cents
($6.87). Market price for the purpose of this Section 6.1 shall mean

                                       4
<PAGE>

the average closing bid price of the Common Stock for ten (10) consecutive
trading days as reported by the Principal Exchange. All Warrants must be
redeemed if any are redeemed.

               6.2 In case the Company shall exercise its right to redeem, it
shall mail a notice of redemption to Holders of the Warrants to be redeemed,
first class, postage prepaid, not later than the thirtieth day before the date
fixed for redemption, at their last address. Any notice mailed in the manner
provided herein shall be conclusively presumed to have been duly given whether
or not the Holder receives such notice.

               6.3 The notice of redemption shall specify the redemption price,
date fixed for redemption, the place where the Warrant shall be delivered and
the redemption price shall be paid, and that the right to exercise the Warrant
shall terminate at 5:00 P.M. (Pacific time) on the business day immediately
preceding the date fixed for redemption. The date fixed for the redemption of
the Warrants shall be the Redemption Date.

               6.4 Any right to exercise a Warrant shall terminate at 5:00 P.M.
(Pacific time) on the business day immediately preceding the Redemption Date. On
and after the Redemption Date, Holders of the Warrants shall have no further
rights except to receive, upon surrender of the Warrant, the redemption price of
$.10 per Warrant.

        7. General Provisions.

               7.1 Complete Agreement; Modifications. This Warrant and any

the party in any such suit or proceeding. Nothing herein shall affect either
party's right to serve process in any other manner permitted by law. Each of the
parties agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
