                  3.1.  PROMISSORY NOTES AND TANGIBLE CHATTEL PAPER. If the
            Company shall at any time hold or acquire any promissory notes or
            tangible chattel paper comprising the Collateral, the Company shall
            forthwith endorse, assign and deliver the same to the Secured Party,

            specify.

                  3.2.  DEPOSIT ACCOUNTS. For each deposit account that the

            pursuant to an agreement in form and substance reasonably
            satisfactory to the Secured Party, either (a) cause the depositary
            bank to agree to comply at any time with instructions from the
            Secured Party to such depositary bank directing the disposition of
            funds from time to time credited to such deposit account, without
            further consent of the Company, or (b) arrange for the Secured Party
            to become the customer of the depositary bank with respect to the

            from such deposit account; provided however, that the Secured Party
            shall only exercise its right to withdraw or otherwise direct funds
            upon the occurrence and continuation of an Event of Default.

                  3.3.  INVESTMENT PROPERTY. If the Company shall at any time
            hold or acquire any securities which are the proceeds of Accounts,
            the Company shall forthwith endorse, assign and deliver the same to

            interest therein.

                  3.4.  COLLATERAL IN THE POSSESSION OF A BAILEE. The Company
            shall not store any Inventory or any other assets comprising
            Collateral with a warehouseman, bailee or other third party unless
            the Company first notifies Secured Party of Company's intention to
            do so and obtains an acknowledgement and waiver from such
            warehouseman, bailee or third party, in form and substance
            reasonably satisfactory to the Secured Party.

                  3.5.  ELECTRONIC CHATTEL PAPER AND TRANSFERABLE RECORDS. If
            the Company at any time holds or acquires an interest in any
            electronic chattel paper or any "transferable record," (as that term
            is defined in Section 201 of the federal Electronic Signatures in
            Global and National Commerce Act, or in Section 16 of the




            Uniform Electronic Transactions Act as in effect in any relevan
            jurisdiction), in each case with respect to the Collateral, the
            Company shall promptly notify the Secured Party thereof and, at the
            request of the Secured Party, shall take such action as the Secured
            Party may reasonably request to vest in the Secured Party control
            under UCC Section 9-105 of such electronic chattel paper or control
            under Section 201 of the federal Electronic Signatures in Global and
            National Commerce Act or, as the case may be, Section 16 of the
            Uniform Electronic Transactions Act, as so in effect in such
            jurisdiction, of such transferable record

                  3.6.  LETTER-OF-CREDIT RIGHTS. If the Company is at any time a
            beneficiary under a letter of credit now or hereafter issued in
            favor of the Company with respect to any Collateral, the Company
            shall promptly notify the Secured Party thereof and, at the request
            and option of the Secured Party, the Company shall, pursuant to an
            agreement in form and substance reasonably satisfactory to the
            Secured Party, either (i) arrange for the issuer and any confirmer
            of such letter of credit to consent to an assignment to the Secured
            Party of the proceeds of any drawing under the letter of credit or
            (ii) arrange for the Secured Party to become the transferee
            beneficiary of the letter of credit, with the Company agreeing, in
            each case, that the proceeds of any drawing under the letter to
            credit are to be applied as directed by Secured Party.

                  3.7.  OTHER ACTIONS AS TO ANY AND ALL COLLATERAL. The Company
            further agrees to take any other action reasonably requested by the
            Secured Party to insure the attachment, perfection and first
            priority of, and the ability of the Secured Party to enforce, the
            Secured Party's security interest in any and all of the Collateral
            including, without limitation, (a) complying with any provision of
            any statute, regulation or treaty of the United States as to any
            Collateral if compliance with such provision is a condition to
            attachment, perfection or priority of, or ability of the Secured
            Party to enforce, the Secured Party's security interest in such
            Collateral, (b) obtaining governmental and other third party
            consents and approvals, including without limitation any consent of

            and other information as Secured Party shall reasonably request, (i)
            if requested by Secured Party, following the occurrence and
            continuance of an Event of Default, Company shall furnish Secured
            Party with copies of all contracts, orders, invoices, and other
            similar documents, and all original shipping instructions, delivery

            goods the sale or disposition of which gave rise to all Accounts
            owing to each MTI Company, and Company warrants the genuineness of
            all of the foregoing, and (j) in the event any account debtor
            returns any Inventory to any MTI Company after the occurrence and
            during the continuance of any Event of Default, such MTI Company
            shall hold the returned Inventory in trust for Secured Party and
            immediately notify Secured Party of the return of any Inventory,
            specifying the reason for such return, the location and condition of
            the returned Inventory, and on Secured Party's request deliver such
            returned Inventory to Secured Party.

                  5.3.  ADDITIONAL COVENANTS. The Company further covenants with
            the Secured Party that, except as set forth in the Schedule of
            Exceptions, the Company shall comply with the following covenants
            and shall cause each other MTI Company to comply with the following
            covenants: (a) (i) no MTI Company will dissolve or liquidate unless
            such MTI Company (x) provides Secured Party 30 days prior written

            Company or another MTI Company that has or promptly will execute and

            requested by Secured Party in respect of Secured Party's security

            date herewith between the Company and the Secured Party, (ii) no MTI
            Company will merge or consolidate with any other entity (except if
            such MTI Company is the surviving entity), and (iii) no MTI Company
            will acquire all or substantially all of the stock of any other
            entity (unless such entity becomes party to the security
            arrangements contemplated hereunder), (b) no MTI Company will
            acquire any assets except in the ordinary course of business;
            provided that the MTI Companies taken as a whole may acquire assets

            transactions in any one fiscal year, (c) no MTI Company will make
            any loans of any money or other assets, except to another MTI

            Party satisfactory security documents with respect to the
            Obligations, (d) no MTI Company will guarantee or otherwise become

            security documents with respect to the Obligations, and (e) in
            addition to the other obligations contained in this Security
            Agreement and the Supply Agreements, each MTI Company promises to
            pay when due all amounts owed under this Security Agreement and the
            Supply Agreements, without setoff or recoupment, the right to which
            is expressly



            waived hereby; provided however that EMC and the MTI Companies may
            recoup amounts owed under the Supply Agreements in the ordinary
            course of business.

                  5.4.  REPRESENTATION, WARRANTIES AND COVENANTS REGARDING
            CONTRACTS WITH GOVERNMENTAL AUTHORITIES. The Company represents and
            warrants that, as of the date hereof, except as set forth in the
            Schedule of Exceptions, none of the account debtors or other persons
            obligated on any of the Collateral or any Accounts owing to any MTI
            Company in an amount in excess of $250,000 is a governmental
            authority subject to the Federal Assignment of Claims Act or like
            foreign, federal, state or local statute or rule in respect of such
            Collateral or Account. Promptly upon any MTI Company entering into
            any contract or agreement with such governmental authority in an
            amount in excess of $250,000, the Company shall notify the Secured
            Party of such transaction, and provide to Secured Party a summary of
            the terms thereof. The Company shall provide to Secured Party such
            additional documents or information relating thereto as Secured
            Party shall reasonably request. The applicable MTI Company shall
            take such steps as Secured Party shall reasonably request to perfect
            Secured Party's lien on the Accounts and other Collateral relating
            to such contracts and agreements with such governmental authority.

      6.    INSURANCE.

                  6.1.  MAINTENANCE OF INSURANCE. The Company will cause each
            MTI Company to maintain with financially sound and reputable
            insurers insurance with respect to its assets against such
            casualties and contingencies as shall be in accordance with general
            practices of businesses engaged in similar activities in similar
            geographic areas. Such insurance shall be in such minimum amounts
            that no MTI Company will be deemed a co-insurer under applicable
            insurance laws, regulations and policies and otherwise shall be in
            such amounts, contain such terms, be in such forms and be for such
            periods as may be reasonably satisfactory to the Secured Party. In
            addition, all such insurance with respect to the Collateral shall be
            payable to the Secured Party as loss payee.

                  6.2.  INSURANCE PROCEEDS. The proceeds of any casualty
            insurance in respect of any casualty loss of any of the Collateral
            shall (i) so long as no Default or Event of Default has occurred and
            is continuing and to the extent that the amount of such proceeds is
            less than $100,000, be disbursed to the Company for direct
            application by the Company solely to the repair or replacement of
            the Company's property so damaged or destroyed and (ii) in all other
            circumstances, be held by the Secured Party as cash collateral for
            the Obligations, or in Secured Party's sole discretion, be applied
            by the Secured Party to the Obligations.

                  6.3.  NOTICE OF CANCELLATION, ETC. All policies of insurance
            with respect to the Collateral shall provide for at least 30 days
            prior written cancellation notice to the Secured Party. In the event
            of failure by the Company to provide and maintain insurance as
            herein provided, the Secured Party may, at its option, provide such
            insurance and charge the amount thereof to the Company. The Company
            shall furnish the Secured Party with certificates of insurance and
            policies evidencing compliance with the foregoing insurance
            provision.

      7.    EVENTS OF DEFAULT. Each of the following events shall be an "EVENT

made for such discharge), bonded, or a stay of execution thereof shall not be
procured, within 60 days from the date of entry thereof and the relevant MTI
Company shall not, within said period of 60 days, or such longer period during

      8.    COLLATERAL PROTECTION EXPENSES; PRESERVATION OF COLLATERAL.

                  8.1.  EXPENSES INCURRED BY SECURED PARTY. If the Company shall
            fail to do so and in its reasonable discretion, the Secured Party
            may discharge taxes and other encumbrances at any time levied or
            placed on any Collateral, make repairs thereto and pay any necessary
            filing fees. The Company agrees to reimburse the Secured Party on
            demand for any and all expenditures so made. The Secured Party shall
            have no obligation to the Company to make any such expenditures, nor
            shall the making thereof relieve the Company of any default.

                  8.2.  SECURED PARTY'S OBLIGATIONS AND DUTIES. Anything herein
            to the contrary notwithstanding, the Company shall remain liable
            under each contract or agreement comprised in the Collateral to be
            observed or performed by the Company thereunder. The Secured Party
            shall not have any obligation or liability under any such contract
            or agreement by reason of or arising out of this Security Agreement
            or the receipt by the Secured Party of any payment relating to any
            of the Collateral, nor shall the Secured Party be obligated in any
            manner to perform any of the obligations of the Company under or
            pursuant to any such contract or agreement, to make inquiry as to
            the nature or sufficiency of any payment received by the Secured
            Party in respect of the Collateral or as to the sufficiency of any
            performance by any party under any such contract or agreement, to
            present or file any claim, to take any action to enforce any
            performance or to collect the payment of any amounts which may have
            been assigned to the Secured Party or to which the Secured Party may
            be entitled at any time or times. The Secured Party's sole duty with
            respect to the custody, safe keeping and physical preservation of
            the Collateral in its possession, under Section 9-207 of the Uniform
            Commercial Code of the State or otherwise, shall be to deal with
            such Collateral in the same manner as the Secured Party deals with
            similar property for its own account.

      9.    SECURITIES AND DEPOSITS. The Secured Party may at any time following
and during the continuance of a Default and Event of Default, at its option,
transfer to itself or any nominee any securities constituting Collateral,
receive any income thereon and hold such income as additional Collateral or
apply it to the Obligations. Whether or not any Obligations are due, the Secured
Party may following and during the continuance of a Default and Event of Default
demand, sue for, collect, or make any settlement or compromise which it deems
desirable with respect to the Collateral. Regardless of the adequacy of
Collateral or any other security for the Obligations, any deposits or other sums
at any time credited by or due from the Secured Party to the Company may at any
time be applied to or set off against any of the Obligations then due.

      10.   LOCKBOX; NOTIFICATION TO ACCOUNT DEBTORS AND OTHER PERSONS OBLIGATED
ON COLLATERAL; VERIFICATION. The Company shall cause all account debtors
obligated on any Accounts to remit all Accounts directly to a lockbox account
maintained with a bank or financial institution designated by the Company and
approved by the Secured Party. The Company shall cause such bank or financial
institution to enter into a control agreement, as set forth in Section 3.2
hereof. Prior to the occurrence of an Event of Default, the Company may freely
withdraw or transfer any sums on deposit in such lockbox account, subject to the
terms of this Security Agreement. Upon the occurrence and during the continuance
of an Event of Default, the Secured Party may, without notice to or demand upon
the Company, (a) exercise its right to control the lockbox account pursuant to
Section 3.2 hereof, and otherwise in accordance with the control agreement with
the bank or financial institution maintaining the lockbox account, and (b)
itself notify account debtors and other persons obligated on Collateral of
Secured Party's rights to the Collateral and Secured Party's exercise of
control. Whether or not there has occurred an Event of Default, the Company
shall, at the request of the Secured Party, notify account debtors and other
persons obligated on any of the Collateral to make payments thereon as directed
by the Secured Party. If the Company receives any proceeds of collections of
Accounts or other Collateral other than through the lockbox account, it shall
immediately deposit such proceeds into the lockbox account, together with any
necessary endorsements or assignments, and until such deposit, the Company shall
hold such proceeds as trustee for the Secured Party without commingling the same
with other funds of the Company. Secured Party may, from time to time, verify
directly with the respective account debtors the validity, amount and other
matters relating to the Accounts, by means of mail, telephone or otherwise,
either in the name of Company or Secured Party or such other name as Secured
Party may choose.

      11.   POWER OF ATTORNEY.

                  11.1. APPOINTMENT AND POWERS OF SECURED PARTY. The Company
            hereby irrevocably constitutes and appoints the Secured Party and
            any officer or agent thereof, with full power of substitution, as
            its true and lawful attorneys-in-fact, with full irrevocable power
            and authority in the place and stead of the



            Company or in the Secured Party's own name, for the purpose of
            carrying out the terms of this Security Agreement, to take any and
            all appropriate action and to execute any and all documents and
            instruments that may be necessary or desirable to accomplish the
            purposes of this Security Agreement, subject to the following:

                        (a)   The Company hereby gives said attorneys the power
and right, on behalf of the Company, without notice to or assent by the Company,
to do the following upon the occurrence and during the continuance of an Event
of Default, generally to sell, transfer, pledge, make any agreement with respect
to or otherwise deal with any of the Collateral in such manner as is consistent
with the Uniform Commercial Code of the State and as fully and completely as
though the Secured Party were the absolute owner thereof for all purposes, and
to do at the Company's expense, at any time, or from time to time, all acts and
things which the Secured Party deems necessary to protect, preserve or realize
upon the Collateral and the Secured Party's security interest therein, in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Company might do, including, without limitation, (i) the execution, delivery
and recording, in connection with any sale or other disposition of any
Collateral, of the endorsements, assignments or other instruments of conveyance
or transfer with respect to such Collateral, and (ii) settle or adjust disputes
or claims directly with account debtors obligated on any Accounts for amounts
and upon terms which Secured Party considers advisable in its reasonable credit
judgment and, in all cases, Secured Party shall credit the Obligations with only
the net amounts received by Secured Party in payment of any Accounts; and

                        (b)   The Company hereby gives said attorneys the power
and right, on behalf of the Company, without notice to or assent by the Company,
whether or not a default or Event of Default has occurred, to the extent that
the Company's authorization given in Section 3 is not sufficient, to file such
financing statements with respect hereto, with or without the Company's
signature, or a photocopy of this Security Agreement in substitution for a
financing statement, as the Secured Party may deem appropriate and to execute in
the Company's name such financing statements and amendments thereto and
continuation statements which may require the Company's signature.

                  11.2. RATIFICATION BY COMPANY. To the extent permitted by law,
            the Company hereby ratifies all that said attorneys shall lawfully
            do or cause to be done by virtue hereof. This power of attorney is a
            power coupled with an interest and shall be irrevocable.

                  11.3. NO DUTY ON SECURED PARTY. The powers conferred on the
            Secured Party hereunder are solely to protect its interests in the
            Collateral and shall not impose any duty upon it to exercise any
            such powers. The Secured Party shall be accountable only for the
            amounts that it actually receives as a result of the exercise of
            such powers, and neither it nor any of its officers, directors,
            employees or agents shall be responsible to the Company for any act
            or failure to act, except for the Secured Party's own gross
            negligence or willful misconduct.

      12.   REMEDIES. If an Event of Default shall have occurred and be
continuing, the Secured Party may, without notice to or demand upon the Company,
declare this Security Agreement to be in default (provided, however, that upon
the occurrence of an Event of Default set forth in Sections 7(b) or 7(c) hereof,
this Security Agreement shall automatically be in default without any
declaration by Secured Party), accelerate the Obligations, and the Secured Party
shall thereafter have in any jurisdiction in which enforcement hereof is sought,
in addition to all other rights and remedies, the rights and remedies of a
secured party under the Uniform Commercial Code of the State or of any
jurisdiction in which Collateral is located, including, without limitation, the
right to take possession of the Collateral, and for that purpose the Secured
Party may, so far as the Company can give authority therefor, enter upon any
premises on which the Collateral may be situated and remove the same therefrom.
The Secured Party may in its discretion require the Company to assemble all or
any part of the Collateral at such location or locations within the
jurisdiction(s) of the Company's principal office(s) or at such other locations
as the Secured Party may reasonably designate. Unless the Collateral is
perishable or threatens to decline speedily in value or is of a type customarily
sold on a recognized market, the Secured Party shall give to the Company at
least ten (10) Business Days prior written notice of the time and place of any
public sale of Collateral or of the time after which any private sale or any
other intended disposition is to be made. The Company hereby acknowledges that
ten (10) Business Days prior written notice of such sale or sales shall be
reasonable notice. In addition, the Company waives any and all rights that it
may have to a judicial hearing in advance of the enforcement of any of the
Secured Party's rights hereunder, including, without limitation, its right
following an Event of Default, to take immediate possession of the Collateral
and to exercise its rights with respect thereto. In addition to any terms and
conditions contained in any



Supply Agreement, goods and services will be sold to Company only if there
exists no default or Event of Default under this Security Agreement.

      13.   NO WAIVER BY SECURED PARTY, ETC. The Secured Party shall not be
deemed to have waived any of its rights upon or under the Obligations or the
Collateral unless such waiver shall be in writing and signed by the Secured
Party. No delay or omission on the part of the Secured Party in exercising any
right shall operate as a waiver of such right or any other right. A waiver on
any one occasion shall not be construed as a bar to or waiver of any right on
any future occasion. All rights and remedies of the Secured Party with respect
to the Obligations or the Collateral, whether evidenced hereby or by any other
instrument or papers, shall be cumulative and may be exercised singularly,
alternatively, successively or concurrently at such time or at such times as the
Secured Party deems expedient.

      14.   SURETYSHIP WAIVERS BY COMPANY. The Company waives demand, notice,
protest, notice of acceptance of this Security Agreement, notice of credit
extended, Collateral received or delivered or other action taken in reliance
hereon and all other demands and notices of any description. With respect to
both the Obligations and (after the occurrence of an Event of Default) the
Collateral, the Company assents to any extension or postponement of the time of
payment or any other indulgence, to any substitution, exchange or release of or
failure to perfect any security interest in any Collateral, to the addition or
release of any party or person primarily or secondarily liable, to the
acceptance of partial payment thereon and the settlement, compromising or
adjusting of any thereof, all in such manner and at such time or times as the
Secured Party may deem advisable. The Secured Party shall have no duty as to the
collection or protection of the Collateral or any income thereon, nor as to the
preservation of rights against prior parties, nor as to the preservation of any
rights pertaining thereto beyond the safe custody thereof as set forth in
Section 11.3. The Company further waives any and all other suretyship defenses.

      15.   MARSHALLING. The Secured Party shall not be required to marshal any
present or future collateral security (including but not limited to this
Security Agreement and the Collateral) for, or other assurances of payment of,
the Obligations or any of them or to resort to such collateral security or other
assurances of payment in any particular order, and all of its rights hereunder
and in respect of such collateral security and other assurances of payment shall
be cumulative and in addition to all other rights, however existing or arising.
To the extent that it lawfully may, the Company hereby agrees that it will not
