                             REGISTRATION AGREEMENT
                            ----------------------


          THIS AGREEMENT is made as of December 23, 1996, between Zytec
Corporation, a Minnesota corporation (the "Company"), BMO Nesbitt Burns Capital
                                           -------
(U.S.), Inc., a Delaware corporation (the "Investor"), and each of the other
                                           --------
individuals and entities set forth under the heading of "Management
Stockholders" on the attached "Schedule of Management Stockholders"
                               -----------------------------------
(collectively, the "Management Stockholders").
                    -----------------------

          The Company and the Investor are parties to a Note and Warrant
Purchase Agreement of even date herewith (the "Purchase Agreement"). In order
                                               ------------------
to induce Investor to enter into the Purchase Agreement, the Company has agreed
to provide the registration rights set forth in this Agreement.  The execution
and delivery of this Agreement is a condition to the Closing under the Purchase
Agreement.  Unless otherwise provided in this Agreement, capitalized terms shall
have the meanings set forth in Section 8 hereof.
                               ---------

          The parties hereto agree as follows:

          1.   Demand Registrations.
               --------------------

          (a)  Requests for Registration.  Subject to subsections (c) and (d)
               -------------------------
below, the holders of a majority of the Investor Registrable Securities may
request registration under the Securities Act of all or any portion of their
Registrable Securities on any registration form available to the Company;
provided that the aggregate offering value of the Registrable Securities
requested to be registered in any Demand Registration must equal at least
$5,000,000. All registrations requested pursuant to this Section 1(a) are
                                                          ------------
referred to herein as "Demand Registrations".  Each request for a Demand
                       --------------------
Registration shall specify the approximate number of Registrable Securities
requested to be registered and the anticipated per share price range for such
offering. Within ten days after receipt of any such request, the Company shall
give written notice of such requested registration to all other holders of
Registrable Securities and, subject to Section 1(c) below, shall include in such
                                       ------------
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within 15 days after the receipt
of the Company's notice. All Demand Registrations shall be underwritten
registrations.

          (b)  Registration Expenses.  The holders of a majority of the Investor
               ---------------------
Registrable Securities shall be entitled to request two registrations in which
the Company shall pay all Registration Expenses. Such registration shall be on
Form S-3 or any successor form, if permitted, or such appropriate registration
form as shall be selected by the Company; provided that if the managing
underwriters advise the Company that in their opinion a different registration
form is required, the Company shall use such registration form chosen by the
managing underwriters. A registration shall not count as one of the permitted
Demand Registrations until it has become effective and a registration shall not
count as one of the permitted Demand Registrations unless the holders of
Investor Registrable Securities are able to register and sell at least 90% of
the Registrable Securities requested to be included in such registration;
provided that in any event the Company shall pay all Registration Expenses in
connection with any registration initiated as a Demand Registration whether or
not it has become effective and whether or not such registration has counted as
one of the permitted Demand Registrations, unless such registration has not
become effective because the holders of a majority of the Investor Registrable
Securities have withdrawn the registration for reasons attributable only to the
holders of such Investor Registrable Securities.

          (c)  Priority on Demand Registrations.  The Company shall not include
               --------------------------------
in any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the holders of a majority of the Investor
Registrable Securities included in such registration. If a Demand Registration
is an underwritten offering involving (i) a directed placement to less than 50
Accredited Investors, (ii) the registration of all of the Registrable Securities
then held by the Investor or (iii) the final Demand Registration available to
the holders of the Investor Registrable Securities, and the managing
underwriters advise the Company in writing that in their opinion the number of
Registrable Securities and, if permitted hereunder, other securities requested
to be included in such offering exceeds the number of Registrable Securities and
other securities, if any, which can be sold in an orderly manner in such
offering within a price range acceptable to the holders of a majority of the
Investor Registrable Securities initially requesting registration, the Company
shall include in such registration (x) first, the Investor Registrable
Securities requested to be included in such registration, (y) second, the
Management Registrable Securities requested to be included in such registration,
pro rata among the holders of such Management Registrable Securities on the
basis of the number of shares owned by such holder (unless otherwise agreed to
by such holders) and (z) third, other securities requested to be included in
such registration. If a Demand Registration is an underwritten offering not
involving clauses (i), (ii) or (iii) above and the managing underwriters advise
the Company in writing that in their opinion the number of Registrable
Securities and, if permitted hereunder, other securities requested to be
included in such offering exceeds the number of Registrable Securities and other
securities, if any, which can be sold in an orderly manner in such offering
within a price range acceptable to the holders of a majority of the Investor
Registrable Securities initially requesting registration, the Company shall
include in such registration (x) first, the Registrable Securities requested to
be included in such registration, pro rata (based upon the number of Registrable
Securities requested to be registered) among the holders of the Investor
Registrable Securities as a group and the holders of the Management Registrable
Securities as a group (with the Management Registrable Securities included in
such registration selected pro rata among the holders of the Management
Registrable Securities requesting to be included in such registration on the
basis of the number of shares owned by each such holder, unless otherwise agreed
to by such holders); provided that the holders of Investor Registrable
Securities shall not be reduced to less than 50% of such offering and (y)
second, other securities requested to be included in such registration.

          (d)  Restrictions on Demand Registrations.  The Company shall not be
               ------------------------------------
obligated to effect any Demand Registration within 270 days after the effective
date of a previous Demand Registration or a previous registration in which the
holders of Registrable Securities were given piggyback rights pursuant to
Section 2.
- ---------

          (e)  Selection of Underwriters.  The Company shall have the right to
               -------------------------
select the investment banker(s) and manager(s) to administer any offering,
subject to the approval of the holders of a majority of the Investor Registrable
Securities included in any Demand Registration which shall not be unreasonably
withheld.

          (f)  Other Registration Rights.  Except as provided in this Agreement,
               -------------------------
the Company shall not grant to any Persons the right to request the Company to
register any equity securities of the Company, or any securities convertible or
exchangeable into or exercisable for such securities, without the prior written
consent of the holders of a majority of the Investor Registrable Securities;
provided that the Company may grant rights to other Persons to (i) participate
in Piggyback Registrations so long as such rights are subordinate to the rights
of the holders of Investor Registrable Securities with respect to such Piggyback
Registrations as set forth in Sections 2(c) and 2(d) hereof and (ii) request
                              -------------     ----
registrations so long as the holders of Investor Registrable Securities are
entitled to participate in any such registrations with such Persons pro rata on
the basis of the number of shares owned by each such holder.

          2.   Piggyback Registrations.
               -----------------------

          (a)  Right to Piggyback.  Whenever the Company proposes to register
               ------------------
any of its securities under the Securities Act (other than pursuant to a Demand
Registration) and the registration form to be used may be used for the
registration of Registrable Securities (a "Piggyback Registration"), the Company
                                           ----------------------
shall give prompt written notice (in any event within three business days after
its receipt of notice of any exercise of demand registration rights other than
under this Agreement) to all holders of Investor Registrable Securities of its
intention to effect such a registra tion and shall include in such registration
all Investor Registrable Securities with respect to which the Company has
received written requests for inclusion therein within 15 days after the receipt
of the Company's notice.

          (b)  Piggyback Expenses.  The Registration Expenses of the holders of
               ------------------
Investor Registrable Securities shall be paid by the Company in all Piggyback
Registrations.

          (c)  Priority on Primary Registrations.  If a Piggyback Registration
               ---------------------------------
is an underwritten primary registration on behalf of the Company, and the
managing underwriters advise the Company in writing (with a copy to each party
requesting registration of Investor Registerable Securities) that in their
opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering without adversely
affecting the marketability of the offering, the Company shall include in such
registration (i) first, the securities the Company proposes to sell, (ii)
second, the Investor Registrable Securities requested to be included in such
registration, pro rata among the holders of such Investor Registrable Securities
on the basis of the number of shares owned by each such holder, and (iii) third,
other securities requested to be included in such registration.

          (d)  Priority on Secondary Registrations.  If a Piggyback Registration
               -----------------------------------
is an underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering without
adversely affecting the marketability of the offering, the Company shall include
in such registration (i) first, the securities requested to be included therein
by the holders requesting such registration and the holders of the Investor
Registrable Securities requested to be included in such registration, pro rata
among the holders of such securities on the basis of the number of shares owned
by each such holder, and (ii) second, other securities requested to be included
in such registration.

          (e)  Selection of Underwriters.  If any Piggyback Registration is an
               -------------------------
underwritten offering, the Company shall select the investment banker(s) and
manager(s) for the offering.

          (f)  Other Registrations.  If the Company has previously filed a
               -------------------
registration statement with respect to Registrable Securities pursuant to
Section 1 or pursuant to this Section 2, and if such previous registration has
- ---------                     ---------
not been withdrawn or abandoned, the Company shall not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act, whether on its own behalf or at the request of any holder or
holders of such securities, until a period of at least 120 days has elapsed from
the effective date of such previous registration.

          3.   Holdback Agreements.
               -------------------

          (a) Each holder of Registrable Securities shall not effect any public
sale or distribution (including sales pursuant to Rule 144) of equity securities
of the Company, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and the 90-day
period beginning on the effective date of any underwritten Demand Registration
or any underwritten Piggyback Registration in which Registrable Securities are
included (except as part of such underwritten registration), unless the
underwriters managing the registered public offering otherwise agree.

          (b) The Company (i) shall not effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and during the
90-day period beginning on the effective date of any underwritten Demand
Registration or any underwritten Piggyback Registration (except as part of such
underwritten registration), unless the underwriters managing the registered
public offering otherwise agree, and (ii) shall cause each holder of at least 5%
(on a fully-diluted basis) of its Common Stock, or any securities convertible
into or exchangeable or exercisable for Common Stock, purchased from the Company
at any time after the date of this Agreement (other than in a registered public
offering) to agree not to effect any public sale or distribution (including
sales pursuant to Rule 144) of any such securities during such period (except as
part of such underwritten registration, if otherwise permitted), unless the
underwriters managing the registered public offering otherwise agree.

          4.   Registration Procedures.  Whenever the holders of Registrable
               -----------------------
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company shall use its best efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof (including the registration of the Note
or the Warrant held by a holder of Registrable Securities requesting
registration as to which the Company has received reasonable assurances that
only Registrable Securities shall be distributed to the public), and pursuant
thereto the Company shall as expeditiously as possible:

          (a) prepare and file with the Securities and Exchange Commission a
registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become effective (provided
that before filing a registration statement or prospectus or any amendments or
supplements thereto, the Company shall furnish to the counsel selected by the
holders of a majority of the Registrable Securities covered by such registration
statement copies of all such documents proposed to be filed, which documents
shall be subject to the review and comment of such counsel);

          (b) notify each holder of Registrable Securities of the effectiveness
of each registration statement filed hereunder and prepare and file with the
Securities and Exchange Commission such amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be
necessary to keep such registration statement effective for a period of not less
than 120 days (subject to extension pursuant to Section 7) and comply with the
                                                ---------
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

          (c) furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d) use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller reasonably requests and do any and all other acts and things which
may be reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such
seller (provided that the Company shall not be required to (i) qualify generally
to do business in any jurisdiction where it would not otherwise be required to
qualify but for this subsection, (ii) subject itself to taxation in any such
jurisdiction or (iii) consent to general service of process in any such
jurisdiction);

          (e) notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such seller, the Company shall
prepare a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not contain an untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading;

          (f) cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on the NASD automated quotation
system and, if listed on the NASD automated quotation system, use its best
efforts to secure designation of all such Registrable Securities covered by such
registra tion statement as a NASDAQ "national market system security" within the
meaning of Rule 11Aa2-1 of the Securities and Exchange Commission or, failing
that, to secure NASDAQ authorization for such Registrable Securities and,
without limiting the generality of the foregoing, to arrange for at least two
market makers to register as such with respect to such Registrable Securities
with the NASD;

          (g) provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities (including, without limitation, effecting a stock split
or a combination of shares);

          (i) make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement;

          (j) otherwise use its best efforts to comply with all applicable rules
and regulations of the Securities and Exchange Commission, and make available to
its security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve months beginning with the first day of
the Company's first full calendar quarter after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder;

          (k) permit any holder of Registrable Securities which holder, in its
sole and exclusive judgment, might be deemed to be an underwriter or a
controlling person of the Company, to participate in the preparation of such
registration or comparable statement and to require the insertion therein of
material, furnished to the Company in writing, which in the reasonable judgment
of such holder and its counsel should be included;

          (l) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any common stock included in such registration statement for sale in any
jurisdiction, the Company shall use its best efforts promptly to obtain the
withdrawal of such order;

          (m) use its best efforts to cause such Registrable Securities covered
by such registration statement to be registered with or approved by such other
governmental agencies or authorities as may be necessary to enable the sellers
thereof to consummate the disposition of such Registrable Securities;

          (n) obtain one or more cold comfort letters, dated the effective date
of such registration statement (and if such registration includes an
underwritten public offering, dated the date of the closing under the
underwriting agreement), signed by the Company's independent public accountants
in customary form and covering such matters of the type customarily covered by
cold comfort letters as the holders of a majority of the Registrable Securities
being sold reasonably request (provided that such Registrable Securities
constitute at least 10% of the securities covered by such registration
statement); and

          (o) provide a legal opinion of the Company's outside counsel, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, dated the date of the closing under
the underwriting agreement), with respect to the registration statement, each
amendment and supplement thereto, the prospectus included therein (including the
preliminary prospectus) and such other documents relating thereto in customary
form and covering such matters of the type customarily covered by legal opinions
of such nature.

          5.   Registration Expenses.
               ---------------------

          (a) All expenses incident to the Company's performance of or
compliance with this Agreement, including without limitation all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, fees and disbursements
of custodians, and fees and disbursements of counsel for the Company and all
independent certified public accountants, underwriters (excluding discounts and
commissions) and other Persons retained by the Company (all such expenses being
herein called "Registration Expenses"), shall be borne as provided in this
               ---------------------
Agreement, except that the Company shall, in any event, pay its internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit or quarterly review, the expense of any liability insurance and
the expenses and fees for listing the securities to be registered on each
securities exchange on which similar securities issued by the Company are then
listed or on the NASD automated quotation system.

          (b) In connection with any Demand Registration and any Piggyback
Registration, each holder of Registrable Securities included in such
registration shall pay the fees and disbursements of its counsel and any
underwriting discounts or commission relating to such holder's Registerable
Securities.

          (c) To the extent Registration Expenses are not required to be paid by
the Company, each holder of securities included in any registration hereunder
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
shall be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.

          6.   Indemnification.
               ---------------

          (a)  Indemnification Obligation of the Company.  The Company agrees to
               -----------------------------------------
indemnify, to the extent permitted by law, each holder of Registrable
Securities, its officers and directors and each Person who controls such holder
(within the meaning of the Securities Act) against all losses, claims, damages,
liabilities and expenses caused by any untrue or alleged untrue statement of
material fact contained in any registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, except insofar as the same are
caused by or contained in any information furnished in writing to the Company by
such holder expressly for use therein or by such holder's failure to deliver a
copy of the registration statement or prospectus or any amendments or
supplements thereto after the Company has furnished such holder with a
sufficient number of copies of the same. In connection with an underwritten
offering, the Company shall indemnify such underwriters, their officers and
directors and each Person who controls such underwriters (within the meaning of
the Securities Act) to the same extent as provided above with respect to the
indemnification of the holders of Registrable Securities.

          (b)  Indemnification of the Company.  In connection with any
               ------------------------------
registration statement in which a holder of Registrable Securities is
participating, each such holder shall furnish to the Company in writing such
information and affidavits as the Company reasonably requests for use in
connection with any such registration statement or prospectus and, to the extent
permitted by law, shall indemnify the Company, its directors and officers and
each Person who controls the Company (within the meaning of the Securities Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue or alleged untrue statement of material fact contained in the
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, but only to the extent that such untrue statement or omission is
contained in any information or affidavit so furnished in writing by such
holder; provided that the obligation to indemnify shall be individual, not joint
and several, for each holder and shall be limited to the net amount of proceeds
received by such holder from the sale of Registrable Securities pursuant to such
registration statement.

          (c)  Indemnification Procedures.  Any Person entitled to
               --------------------------
indemnification hereunder shall (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification
(provided that the failure to give prompt notice shall not impair any Person's
right to indemnification hereunder to the extent such failure has not prejudiced
the indemnifying party) and (ii) unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party shall not
be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent shall not be unreasonably withheld). An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim shall not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim.

          (d)  Other Indemnification Provisions.  The indemnification provided
               --------------------------------
for under this Agreement shall remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling Person of such indemnified party and shall survive the
transfer of securities. The Company also agrees to make such provisions, as are
reasonably requested by any indemnified party, for contribution to such party in
the event the Company's indemnification is unavailable for any reason.

          7.   Participation in Underwritten Registrations. No Person may
               -------------------------------------------
participate in any registration hereunder which is underwritten unless such
Person (i) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements (including, without limitation, pursuant to the
terms of any over-allotment or "green shoe" option requested by the managing
underwriter(s), provided that no holder of Registrable Securities will be
required to sell more than the number of Registrable Securities that such holder
has requested the Company to include in any registration) and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements. Each Person that is participating in any registration
hereunder agrees that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 4(e) above, such
                                                       ------------
Person will forthwith discontinue the disposition of its Registrable Securities
pursuant to the registration statement until such Person's receipt of the copies
of a supplemented or amended prospectus as contemplated by such Section 4(e).
                                                                ------------
In the event the Company shall give any such notice, the applicable time period
mentioned in Section 4(b) during which a Registration Statement is to remain
             ------------
effective shall be extended by the number of days during the period from and
including the date of the giving of such notice pursuant to this Section 7 to
                                                                 ---------
and including the date when each seller of a Registrable Security covered by
such registration statement shall have received the copies of the supplemented
or amended prospectus contemplated by Section 4(e).
                                      ------------

          8.   Definitions.

               --------------------------------------------
not take any action, or permit any change to occur, with respect to its

(including, without limitation, effecting a stock split or a combination of

          (c)  Remedies.  Any Person having rights under any provision of this
               --------
Agreement shall be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of

relief in order to enforce or prevent violation of the provisions of this

               ----------------------

provisions of this Agreement may be amended or waived only upon the prior
written consent of the Company and holders of a majority of the Registrable

not affect the right of such party thereafter to enforce each and every
provision in accordance with its terms.

          (e)  Successors and Assigns.  All covenants and agreements in this
               ----------------------
Agreement by or on behalf of any of the parties hereto shall bind and inure to
the benefit of and be enforceable by the respective successors and assigns of
the parties hereto whether so expressed or not. In addition, and whether or not
any express assignment has been made, the provisions of this Agreement which are
for the benefit of purchasers or holders of Registrable Securities are also for
the benefit of, and enforceable by, any subsequent holder of Registrable
Securities, subject to the provisions respecting the minimum numbers or
percentages of shares of Registrable Securities required in order to be entitled

          (f)  Severability.  Whenever possible, each provision of this
               ------------
Agreement shall be interpreted in such manner as to be effective and valid
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or the effectiveness or validity of any provision in any
other jurisdiction, and this Agreement shall be reformed, construed and enforce
in such jurisdiction as if such invalid, illegal or unenforceable provision had
never been contained herein.

          (g)  Counterparts.  This Agreement may be executed simultaneously in
               ------------
two or more counterparts, any one of which need not contain the signatures of
more than one party, but all such counterparts taken together shall constitute
one and the same Agreement.
