                               SECURITY AGREEMENT

                  SECURITY AGREEMENT (this "Agreement") made this 31st day of
January, 2001, by and between DATAMETRICS CORPORATION, a Delaware corporation,
having an office at 1717 Diplomacy Row, Orlando, Florida 32809 (the "Debtor"),
and DMTR, LLC, a New York limited liability company having an office at 1325
Avenue of the Americas, 26th Floor, New York, New York 10019 (the "Secured
Party");

                              W I T N E S S E T H:

                  WHEREAS, the Debtor has executed and delivered a Secured
Promissory Note dated the date hereof (the "Note") in favor of the Secured Party
in connection with a loan (the "Loan") to the Debtor pursuant to that certain
Loan Agreement dated the date hereof (the "Loan Agreement") between the Debtor
and the Secured Party; and

                  WHEREAS, it is a term of the Loan Agreement and the Note that
the Debtor shall execute and deliver this Agreement;

                  NOW, THEREFORE, in consideration of the premises and mutual
covenants herein contained and in order to satisfy a condition in the Loan
Agreement and the Note, the Secured Party and the Debtor agree as follows:

1.       SECURITY INTEREST.

                  To secure the due payment and performance of all indebtedness
and all other liabilities and obligations relating to such indebtedness, whether
now existing or hereafter arising and whether actual or contingent, of the
Debtor to the Secured Party under the Loan Agreement and the Note, including,
without limitation, any future advances, and all instruments, agreements and
documents executed, issued and delivered pursuant thereto, including, without
limitation, this Agreement (all hereinafter referred to collectively as the
"Secured Obligations"), the Debtor hereby assigns, pledges, hypothecates,
transfers and sets over to the Secured Party and grants to the Secured Party, a
lien upon and security interest in all assets of the Debtor set forth, referred
to, or listed on Schedule I annexed hereto and made a part hereof (all
hereinafter referred to as the "Collateral"). The Debtor expressly confirms, and
the Secured Party hereby acknowledges, that the Collateral (or a part thereof)
is subject to liens and security interests previously granted by the Debtor to
the payees of the 1999 Note and the Bridge Notes, as those terms are defined in
the Loan Agreement. and the Debtor acknowledges that such liens and security
interests have been assigned to the Secured Party and affirms such assignment.

2.       DEBTOR'S TITLE; LIENS AND ENCUMBRANCES.

                  The Debtor represents and warrants that the Debtor is, or to
the extent that this Agreement states that the Collateral is to be acquired
after the date hereof, will be, the owner of the Collateral, having good title
thereto, free from any and all liens, security interests, encumbrances and
claims except for liens granted pursuant hereto and as otherwise disclosed
herein or in the Loan Agreement. Except as so otherwise disclosed, the Debtor
will not create or assume or permit to exist any such lien, security interest,
encumbrance or claim on or against the Collateral except as created by this
Agreement, and the Debtor will promptly notify the Secured Party of any such
other claim, lien, security interest or other encumbrance made or asserted
against the Collateral and will defend against any such claim, lien, security
interest or other encumbrance.

3.       LOCATION OF COLLATERAL AND RECORDS.

                  The Debtor represents and warrants that it has no place of
business or offices where the Debtor's books of account and records are kept, or
places where the Collateral is used, stored or located, except as set forth on
Schedule II annexed hereto and except for Collateral in transit in the ordinary
course of business, and covenants that the Debtor will notify the Secured Party
of any change in the foregoing representation within ten days before any such
change. The Debtor shall at all times maintain its records as to the Collateral
at its chief place of business at the address referred to on Schedule II and at
none other. The Debtor further covenants that except for Collateral delivered to
the Secured Party, the Debtor will not store, use or locate any of the
Collateral at any place other than as listed on Schedule II annexed hereto,
except for Collateral in transit in the ordinary course of business and except
for Collateral requiring necessary repair, provided that prior to the Collateral
being relocated for such repair the Debtor gives written notice to the Secured
Party of the Debtor's intent to relocate such Collateral and describes where the
Collateral will be relocated and the nature of the repair required and further
provided that the Collateral is returned to its location from which it was moved
for such repair no later than 90 days after it was removed for such repair.

4.       PERFECTION OF SECURITY INTEREST.

                  The Debtor will join with the Secured Party in executing one
or more financing statements pursuant to the Uniform Commercial Code or other
notices appropriate under applicable law in form satisfactory to the Secured
Party and will pay all filing or recording costs with respect thereto, and all
costs of filing or recording this Agreement or any other instrument, agreement
or document executed and delivered pursuant hereto (including the cost of all
federal, state or local mortgage, documentary, stamp or other taxes), in each
case, in all public offices where filing or recording is reasonably deemed by
the Secured Party to be necessary or desirable. The Debtor hereby authorizes the
Secured Party to take all action (including, without limitation, the filing of
any Uniform Commercial Code Financing Statements or amendments thereto without
the signature of the Debtor) which the Secured Party may reasonably deem
necessary or desirable to perfect or otherwise protect the liens and security
interests created hereunder and to obtain the benefits of this Agreement.

         Pursuant to the terms hereof, upon the request of the Secured Party
(subject, however, to the rights of any holders of superior liens or security
interests relating to the Collateral), the Debtor will endorse, assign and
deliver to the Secured Party all negotiable or non-negotiable instruments
(including certificated securities) and chattel paper pledged by the Debtor
hereunder, together with instruments of transfer or assignment duly executed in
blank as the Secured Party may have specified. In the event that the Debtor
shall, after the date of this Agreement, acquire any other negotiable or
non-negotiable instruments (including certificated securities) or chattel paper
to be pledged by the Debtor hereunder, upon the request of the Secured Party
(subject, however, to the rights of any holders of superior liens or security
interests relating to the Collateral), the Debtor shall forthwith endorse,
assign and deliver the same to the Secured Party, accompanied by such
instruments of transfer or assignment duly executed in blank as the Secured
Party may from time to time specify. To the extent that any securities are
uncertificated, appropriate book-entry transfers reflecting the pledge of such
securities created hereby have been or, in the case of uncertificated securities
hereafter acquired by the Debtor, will at the time of such acquisition be, duly
made for the account of the Secured Party or one or more nominees of the Secured
Party with the issuer of such securities or other appropriate book-entry
facility or financial intermediary, with the Secured Party having at all times
the right to obtain definitive certificates (in the Secured Party's name or in
the name of one or more nominees of the Secured Party) where the issuer
customarily or otherwise issues certificates, all to be held as Collateral
hereunder (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral). The Debtor hereby acknowledges
that the Secured Party may, in its discretion, appoint one or more financial
institutions to act as the Secured Party's agent in holding in custodial
accounts instruments or other financial assets in

                                       2
<PAGE>

which the Secured Party is granted a security interest hereunder, including,
without limitation, certificates of deposit and other instruments evidencing
short term obligations.

5.       GENERAL COVENANTS.

                  The Debtor shall:

                  a) furnish the Secured Party from time to time at the Secured
Party's request written statements and schedules further identifying and
describing the Collateral in such detail as the Secured Party may reasonably
require;

                  b) advise the Secured Party promptly, in sufficient detail, of
any substantial change in the Collateral, and of the occurrence of any event
which would have a material adverse effect on the value of the Collateral or on
the Secured Party's security interest therein;

                  c) comply with all acts, rules, regulations and orders of any
legislative, administrative or judicial body or official applicable to the
Collateral or any part thereof or to the operation of the Debtor's business,
provided that the Debtor may contest any acts, rules, regulations, orders and
directions of such bodies or officials in any reasonable manner which will not,
in the Debtor's reasonable judgment, adversely affect its rights or the priority
of the Secured Party's security interest in the Collateral;

                  d) perform and observe any and all covenants, restrictions and
conditions contained in the Note and the Loan Agreement providing for payment of
taxes, maintenance of insurance and otherwise relating to the Collateral, as
though such covenants, restrictions and conditions were fully set forth in this
Agreement;

                  e) promptly execute and deliver to the Secured Party such
further assignments, security agreements or other instruments, documents,
certificates and assurances and take such further action as the Secured Party
may from time to time in its sole discretion deem necessary to perfect, protect
or enforce its security interest in the Collateral or otherwise to effectuate
the intent of this Agreement and the Note and the Loan Agreement (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral); and

                  f) defend the Collateral against any claims and demands of all
other persons at any time claiming the same or an interest therein which would
conflict with any claim or interest of the Secured Party (subject, however, to
the rights of any holders of superior liens or security interests relating to
the Collateral). The Debtor will not encumber, sell, transfer, assign, abandon
or otherwise dispose of the Collateral except for: i) collection, discharge,
discount, compromise or expiration of the accounts, instruments or general
intangibles in the ordinary course of the Debtor's business, ii) sale or
transfer of inventory in the ordinary course of business, iii) liens, if any,
allowed under the Loan Agreement and the Note, iv) dispositions, if any, allowed
under the Loan Agreement and the Note, of items of equipment no longer useful to
the Debtor in the ordinary course of business, and v) trade-ins, replacements or
exchanges of items of equipment for other items of equipment having an equal or
greater value (in excess of any purchase money liens on such other items) and
useful in the Debtor's business.

6.       ASSIGNMENT OF INSURANCE.

                  Upon the request of the Secured Party, the Debtor shall cause
the Collateral to be covered by insurance of a type and in an amount that
prudent business people engaged in the same or similar businesses would carry
for the same or similar Collateral (and in all events satisfactory to the
Secured Party) and shall deliver to the Secured Party copies of, or certificates
of the issuing companies with respect to, endorsements of any and all policies
of insurance owned by the Debtor covering or in any

                                       3
<PAGE>

manner relating to the Collateral, in form and substance satisfactory to the
Secured Party, naming the Secured Party as an additional insured party as its
interest may appear and indicating that the policy will not be terminated, or
reduced in coverage or amount, without at least ten (10) days' prior written
notice from the insurer to the Secured Party. As further security for the due
payment and performance of the Secured Obligations (subject, however, to the
rights of any holders of superior liens or security interests relating to the
Collateral), the Debtor hereby assigns to the Secured Party all sums, including
returned or unearned premiums, which may become payable under or in respect of
any policy of insurance owned by the Debtor covering or in any manner relating
to the Collateral, and the Debtor hereby directs that upon an Event of Default
as specified or defined in the Loan Agreement or the Note (hereinafter referred
to as a "Default"), each insurance company issuing any such policy make payment
of sums which may become payable thereunder directly to the Secured Party
(subject, however, to the rights of any holders of superior liens or security
interests relating to the Collateral). Upon the occurrence of a Default, the
Debtor hereby appoints the Secured Party as the Debtor's attorney-in-fact and in
the Debtor's or in the Secured Party's name to endorse any check or draft
representing any such payment and to execute any proof of claim, subrogation
receipt and any other document required by such insurance company as a condition
to or otherwise in connection with such payment, and, upon the occurrence of a
Default, to cancel, assign or surrender any such policies. All such sums
received by the Secured Party shall be applied by the Secured Party in
satisfaction of the Secured Obligations (subject, however, to the rights of any
holders of superior liens or security interests relating to the Collateral) or,
to the extent that such sums represent unearned premiums in respect of any
policy of insurance on the Collateral refunded by reason of cancellation, toward
payment for similar insurance protecting the respective interests of the Debtor
and the Secured Party, or as otherwise required by applicable law, and to the
extent not so applied shall be paid over to the Debtor (subject, however, to the
rights of any holders of superior liens or security interests relating to the
Collateral).

7.       FIXTURES.

                  It is the intent of the Debtor and the Secured Party that none
of the Collateral shall be regarded as fixtures, as that term is used or defined
in Article 9 of the Uniform Commercial Code, and the Debtor represents and
warrants that it has not made and is not bound by any lease or other agreement
which is inconsistent with such intent. Nevertheless, if the Collateral or any
part thereof is or is to become attached or affixed to any real estate, the
Debtor will, upon request, use reasonable efforts to furnish the Secured Party
with a disclaimer or subordination in form satisfactory to the Secured Party of
its interests in the Collateral from all persons having an interest in the real
estate to which the Collateral is attached or affixed, together with the names
and addresses of the record owners of, and all other persons having an interest
in, and a general description of, such real estate.

8.       COLLECTIONS.

                  In the event of the occurrence of any Default (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral), the Debtor will immediately upon receipt of all
checks, drafts, cash or other remittances in payment of any of its accounts,
accounts receivable, contract rights or general intangibles constituting part of
the Collateral, or in payment for any Collateral sold, transferred, leased or
otherwise disposed of, or in payment or on account of its accounts, accounts
receivable, contracts, contract rights, notes, drafts, acceptances, general
intangibles, choses in action and all other forms of obligations relating to any
of the Collateral so sold, transferred or otherwise disposed of, deliver any
such items to the Secured Party accompanied by a remittance report in form
supplied or approved by the Secured Party, such items to be delivered to the
Secured Party in the same form received, endorsed or otherwise assigned by the
Debtor where necessary to permit collection of such items and, regardless of the
form of such endorsement, the Debtor hereby waives presentment, demand, notice
of dishonor, protest, notice of protest and all other notices with respect
thereto. All such remittances (subject, however, to the rights of any holders of
superior liens or security interests relating to the Collateral) shall be
applied and credited by the Secured Party first to satisfaction of the Secured

                                       4
<PAGE>

Obligations or as otherwise required by applicable law, and to the extent not so
credited or applied, shall be paid over to the Debtor.

9.       RIGHTS AND REMEDIES ON DEFAULT.

                  In the event of the occurrence of any Default (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral), the Secured Party shall at any time thereafter have
the right, with or without notice to the Debtor, as to any or all of the
Collateral, by any available judicial procedure, or without judicial process, to
take possession of the Collateral and without liability for trespass to enter
any premises where the Collateral may be located for the purpose of taking
possession of or removing the Collateral, and, generally, to exercise any and
all rights afforded to a secured party under the applicable Uniform Commercial
Code or other applicable law. Without limiting the generality of the foregoing,
the Debtor agrees that in the event of any occurrence of a Default, the Secured
Party shall have the right to sell, lease, or otherwise dispose of all or any
part of the Collateral, whether in its then condition or after further
preparation or processing, either at public or private sale or at any broker's
board, in lots or in bulk, for cash or for credit, with or without warranties or
representations, and upon such terms and conditions, all as the Secured Party in
its sole discretion may deem advisable, and it shall have the right to purchase
at any such sale; and, if any Collateral shall require rebuilding, repairing,
maintenance, preparation, or is in process or other unfinished state, the
Secured Party shall have the right, at its option, to do such rebuilding,
repairing, preparation, processing or completion of manufacturing, for the
purpose of putting the Collateral in such saleable or disposable form as it
shall deem appropriate. At the Secured Party's request (subject, however, to the
rights of any holders of superior liens or security interests relating to the
Collateral), the Debtor shall assemble the Collateral and make it available to
the Secured Party at places which the Secured Party shall reasonably select,
whether at the Debtor's premises or elsewhere, and make available to the Secured
Party, without rent, all of the Debtor's premises and facilities for the purpose
of the Secured Party's taking possession of, removing or putting the Collateral
in saleable or disposable form. The proceeds of any such sale, lease or other
disposition of the Collateral shall (subject, however, to the rights of any
holders of superior liens or security interests relating to the Collateral) be
applied first, to the expenses of retaking, holding, storing, processing and
preparing for sale, selling, and the like, and to the reasonable attorneys' fees
and legal expenses incurred by the Secured Party, and then to satisfaction of
the Secured Obligations, and to the payment of any other amounts required by
applicable law, after which the Secured Party shall account to the Debtor for
any surplus proceeds. If, upon the sale, lease or other disposition of the
Collateral, the proceeds thereof are insufficient to pay all amounts to which
the Secured Party is legally entitled, the Debtor will be liable for the
deficiency, together with interest thereon, to the extent permitted by
applicable law, at the rate, if any, prescribed in the Notes, and the reasonable
fees of any attorneys employed by the Secured Party to collect such deficiency.
To the extent permitted by applicable law, the Debtor waives all claims, damages
and demands against the Secured Party arising out of the repossession, removal,
retention or sale of the Collateral, except for such claims, damages and demands
premised on the gross negligence or willful malfeasance of the Secured Party.

10.      NOTIFICATION TO ACCOUNT DEBTORS AND OTHER OBLIGORS.

                  In the event of the occurrence of any Default, the Debtor
shall (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral), at the request of the Secured
Party, notify account debtors on accounts, accounts receivable, chattel papers
and general intangibles of the Debtor and obligors on instruments for which the
Debtor is an obligee, of the security interest of the Secured Party in any
account, account receivable, chattel paper, general intangible or instrument and
that payment thereof is to be made directly to the Secured Party or to any
financial institution designated by the Secured Party as the Secured Party's
agent therefor, and the Secured Party may itself (subject, however, to the
rights of any holders of superior liens or security interests relating to the
Collateral), if a Default shall have occurred, without notice to or demand upon
the Debtor, so notify account debtors and obligors. After the making of such a
request or the giving of any such notification,

                                       5
<PAGE>

the Debtor shall (subject, however, to the rights of any holders of superior
liens or security interests relating to the Collateral) hold any proceeds of
collection of accounts, accounts receivable, chattel paper, general intangibles
and instruments received by the Debtor as trustee for the Secured Party without
commingling the same with other funds of the Debtor and shall promptly turn the
same over to the Secured Party in the identical form received, together with any
necessary endorsements or assignments. The Secured Party shall (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral) apply the proceeds of collection of accounts,
accounts receivable, chattel paper, general intangibles and instruments received
by the Secured Party to the Secured Obligations, such proceeds to be immediately
entered after final payment in cash or solvent credits of the items giving rise
to them.

11.      COSTS AND EXPENSES.

                  Any and all fees, costs and expenses, of whatever kind or
nature, including the reasonable attorneys' fees and legal expenses incurred by
the Secured Party, in connection with the preparation of this Agreement and all
other documents relating hereto and the consummation of this transaction, the
filing or recording of financing statements and other documents (including all
taxes in connection therewith) in public offices, the payment or discharge of
any taxes, insurance premiums, encumbrances or otherwise protecting, maintaining
or preserving the Collateral, or the enforcing, foreclosing, retaking, holding,
storing, processing, selling or otherwise realizing upon the Collateral and the
Secured Party's security interest therein, whether through judicial proceedings
or otherwise, or in defending or prosecuting any actions or proceedings arising
out of or related to the transaction to which this Agreement relates, shall be
borne and paid by the Debtor on demand by the Secured Party and until so paid
shall be added to the principal amount of the Secured Obligations and shall bear
interest at the rate prescribed in the Notes and shall be secured by the
Collateral.

12.      POWER OF ATTORNEY.

                  Upon the occurrence of a Default, the Debtor authorizes the
Secured Party and does hereby make, constitute and appoint the Secured Party,
and any officer or agent of the Secured Party, with full power of substitution,
as the Debtor's true and lawful attorney-in-fact coupled with an interest, with
power, in its own name or in the name of Debtor, upon the occurrence of a
Default (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral) to endorse any notes, checks,
drafts, money orders, or other instruments of payment (including payments
payable under or in respect of any policy of insurance) in respect of the
Collateral that may come into possession of the Secured Party; to sign and
endorse any invoice, freight or express bill, bill of lading, storage or
warehouse receipts, drafts against debtors, assignments, verifications and
notices in connection with accounts, and other documents relating to Collateral;
to pay or discharge taxes, liens, security interests or other encumbrances at
any time levied or placed on or threatened against the Collateral; to demand,
collect, receipt for, compromise, settle and sue for monies due in respect of
the Collateral; and, generally, to do, at the Secured Party's option and at the
Debtor's expense, at any time, or from time to time, all acts and things which
the Secured Party deems reasonably necessary to protect, preserve and realize
upon the Collateral and the Secured Party's security interest therein in order
to effect the intent of this Agreement and of the Notes all as fully and
effectually as the Debtor might or could do; and the Debtor hereby ratifies all
that said attorney shall lawfully do or cause to be done by virtue hereof. This
power of attorney shall be irrevocable for the term of this Agreement and
thereafter as long as any of the Secured Obligations shall be outstanding.

                               SECURITY AGREEMENT

                  SECURITY AGREEMENT (this "Agreement") made this 31st day of
January, 2001, by and between MADEMYWAY.COM, INC., a Delaware corporation,
having an office at 1717 Diplomacy Row, Orlando Florida 32809 (the "Debtor"),
and DMTR, LLC, a New York limited liability company, having an office at 1325
Avenue of the Americas, 26th Floor, New York, New York 10019 (the "Secured
Party");

                              W I T N E S S E T H:

                  WHEREAS, the parent of the Debtor, Datametrics Corporation
(the "Corporation"), has executed and delivered a Secured Promissory Note dated
the date hereof (the "Note") in favor of the Secured Party in connection with a
loan (the "Loan") to the Corporation pursuant to that certain Loan Agreement
dated the date hereof (the "Loan Agreement") between the Corporation and the
Secured Party; and

                  WHEREAS, it is a term of the Loan Agreement and the Note that
the Debtor shall execute and deliver this Agreement; and

                  WHEREAS, the Debtor will derive substantial benefits from the
Loan;

                  NOW, THEREFORE, in consideration of the premises and mutual
covenants herein contained and in order to satisfy a condition in the Loan
Agreement and the Note, the Secured Party and the Debtor agree as follows:

1.       SECURITY INTEREST.

                  To secure the due payment and performance of all indebtedness
and all other liabilities and obligations relating to such indebtedness, whether
now existing or hereafter arising and whether actual or contingent, of the
Corporation to the Secured Party under the Loan Agreement and the Note,
including, without limitation, any future advances, and all instruments,
agreements and documents executed, issued and delivered pursuant thereto,
including, without limitation, this Agreement (all hereinafter referred to
collectively as the "Secured Obligations"), the Debtor hereby assigns, pledges,
hypothecates, transfers and sets over to the Secured Party and grants to the
Secured Party, a lien upon and security interest in all assets of the Debtor set
forth, referred to, or listed on Schedule I annexed hereto and made a part
hereof (all hereinafter referred to as the "Collateral"). The Debtor expressly
confirms, and the Secured Party hereby acknowledges, that the Collateral (or a
part thereof) is subject to liens and security interests previously granted by
the Debtor to the payees of the Bridge Notes, as that term is defined in the
Loan Agreement, and the Debtor acknowledges that such liens and security
interests have been assigned to the Security Party and affirms such assignment.

2.       DEBTOR'S TITLE; LIENS AND ENCUMBRANCES.

                  The Debtor represents and warrants that the Debtor is, or to
the extent that this Agreement states that the Collateral is to be acquired
after the date hereof, will be, the owner of the Collateral, having good title
thereto, free from any and all liens, security interests, encumbrances and
claims except for liens granted pursuant hereto and as otherwise disclosed
herein or in the Loan Agreement. Except as so otherwise disclosed, the Debtor
will not create or assume or permit to exist any

<PAGE>

such lien, security interest, encumbrance or claim on or against the Collateral
except as created by this Agreement, and the Debtor will promptly notify the
Secured Party of any such other claim, lien, security interest or other
encumbrance made or asserted against the Collateral and will defend against any
such claim, lien, security interest or other encumbrance.

3.       LOCATION OF COLLATERAL AND RECORDS.

                  The Debtor represents and warrants that it has no place of
business or offices where the Debtor's books of account and records are kept, or
places where the Collateral is used, stored or located, except as set forth on
Schedule II annexed hereto and except for Collateral in transit in the ordinary
course of business, and covenants that the Debtor will notify the Secured Party
of any change in the foregoing representation within ten days before any such
change. The Debtor shall at all times maintain its records as to the Collateral
at its chief place of business at the address referred to on Schedule II and at
none other. The Debtor further covenants that except for Collateral delivered to
the Secured Party, the Debtor will not store, use or locate any of the
Collateral at any place other than as listed on Schedule II annexed hereto,
except for Collateral in transit in the ordinary course of business and except
for Collateral requiring necessary repair, provided that prior to the Collateral
being relocated for such repair the Debtor gives written notice to the Secured
Party of the Debtor's intent to relocate such Collateral and describes where the
Collateral will be relocated and the nature of the repair required and further
provided that the Collateral is returned to its location from which it was moved
for such repair no later than 90 days after it was removed for such repair.

4.       PERFECTION OF SECURITY INTEREST.

                  The Debtor will join with the Secured Party in executing one
or more financing statements pursuant to the Uniform Commercial Code or other
notices appropriate under applicable law in form satisfactory to the Secured
Party and will pay all filing or recording costs with respect thereto, and all
costs of filing or recording this Agreement or any other instrument, agreement
or document executed and delivered pursuant hereto (including the cost of all
federal, state or local mortgage, documentary, stamp or other taxes), in each
case, in all public offices where filing or recording is reasonably deemed by
the Secured Party to be necessary or desirable. The Debtor hereby authorizes the
Secured Party to take all action (including, without limitation, the filing of
any Uniform Commercial Code Financing Statements or amendments thereto without
the signature of the Debtor) which the Secured Party may reasonably deem
necessary or desirable to perfect or otherwise protect the liens and security
interests created hereunder and to obtain the benefits of this Agreement.

                  Pursuant to the terms hereof, upon the request of the Secured
Party (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral), the Debtor will endorse, assign
and deliver to the Secured Party all negotiable or non-negotiable instruments
(including certificated securities) and chattel paper pledged by the Debtor
hereunder, together with instruments of transfer or assignment duly executed in
blank as the Secured Party may have specified. In the event that the Debtor
shall, after the date of this Agreement, acquire any other negotiable or
non-negotiable instruments (including certificated securities) or chattel paper
to be pledged by the Debtor hereunder, upon the request of the Secured Party
(subject, however, to the rights of any holders of superior liens or security
interests relating to the Collateral), the Debtor shall forthwith endorse,
assign and deliver the same to the Secured Party, accompanied by such
instruments of transfer or assignment duly executed in blank as the Secured
Party may from time to time specify. To the extent that any securities are
uncertificated, appropriate book-entry transfers reflecting the pledge of such
securities created hereby have been or, in the case of uncertificated securities
hereafter acquired by the Debtor, will at the time of such acquisition be, duly
made for the account of the Secured Party or one or more nominees of the Secured
Party with the issuer of such securities or other appropriate book-entry
facility or financial intermediary, with the Secured Party having at all times
the right to obtain definitive certificates (in the Secured Party's name or in
the name of one or more nominees of the Secured Party) where the issuer

                                       2
<PAGE>

customarily or otherwise issues certificates, all to be held as Collateral
hereunder (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral). The Debtor hereby acknowledges
that the Secured Party may, in its discretion, appoint one or more financial
institutions to act as the Secured Party's agent in holding in custodial
accounts instruments or other financial assets in which the Secured Party is
granted a security interest hereunder, including, without limitation,
certificates of deposit and other instruments evidencing short term obligations.

5.       GENERAL COVENANTS.

                  The Debtor shall:

                  a) furnish the Secured Party from time to time at the Secured
Party's request written statements and schedules further identifying and
describing the Collateral in such detail as the Secured Party may reasonably
require;

                  b) advise the Secured Party promptly, in sufficient detail, of
any substantial change in the Collateral, and of the occurrence of any event
which would have a material adverse effect on the value of the Collateral or on
the Secured Party's security interest therein;

                  c) comply with all acts, rules, regulations and orders of any
legislative, administrative or judicial body or official applicable to the
Collateral or any part thereof or to the operation of the Debtor's business,
provided that the Debtor may contest any acts, rules, regulations, orders and
directions of such bodies or officials in any reasonable manner which will not,
in the Debtor's reasonable judgment, adversely affect its rights or the priority
of the Secured Party's security interest in the Collateral;

                  d) perform and observe any and all covenants, restrictions and
conditions contained in the Note and the Loan Agreement providing for payment of
taxes, maintenance of insurance and otherwise relating to the Collateral, as
though such covenants, restrictions and conditions were fully set forth in this
Agreement;

                  e) promptly execute and deliver to the Secured Party such
further assignments, security agreements or other instruments, documents,
certificates and assurances and take such further action as the Secured Party
may from time to time in its sole discretion deem necessary to perfect, protect
or enforce its security interest in the Collateral or otherwise to effectuate
the intent of this Agreement and the Note and the Loan Agreement (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral); and

                  f) defend the Collateral against any claims and demands of all
other persons at any time claiming the same or an interest therein which would
conflict with any claim or interest of the Secured Party (subject, however, to
the rights of any holders of superior liens or security interests relating to
the Collateral). The Debtor will not encumber, sell, transfer, assign, abandon
or otherwise dispose of the Collateral except for: i) collection, discharge,
discount, compromise or expiration of the accounts, instruments or general
intangibles in the ordinary course of the Debtor's business, ii) sale or
transfer of inventory in the ordinary course of business, iii) liens, if any,
allowed under the Loan Agreement and the Note, iv) dispositions, if any, allowed
under the Loan Agreement and the Note, of items of equipment no longer useful to
the Debtor in the ordinary course of business, and v) trade-ins, replacements or
exchanges of items of equipment for other items of equipment having an equal or
greater value (in excess of any purchase money liens on such other items) and
useful in the Debtor's business.

                                       3
<PAGE>

6.       ASSIGNMENT OF INSURANCE.

                  Upon the request of the Secured Party, the Debtor shall cause
the Collateral to be covered by insurance of a type and in an amount that
prudent business people engaged in the same or similar businesses would carry
for the same or similar Collateral (and in all events satisfactory to the
Secured Party) and shall deliver to the Secured Party copies of, or certificates
of the issuing companies with respect to, endorsements of any and all policies
of insurance owned by the Debtor covering or in any manner relating to the
Collateral, in form and substance satisfactory to the Secured Party, naming the
Secured Party as an additional insured party as its interest may appear and
indicating that the policy will not be terminated, or reduced in coverage or
amount, without at least ten (10) days' prior written notice from the insurer to
the Secured Party. As further security for the due payment and performance of
the Secured Obligations (subject, however, to the rights of any holders of
superior liens or security interests relating to the Collateral), the Debtor
hereby assigns to the Secured Party all sums, including returned or unearned
premiums, which may become payable under or in respect of any policy of
insurance owned by the Debtor covering or in any manner relating to the
Collateral, and the Debtor hereby directs that upon an Event of Default as
specified or defined in the Loan Agreement or the Note (hereinafter referred to
as a "Default"), each insurance company issuing any such policy make payment of
sums which may become payable thereunder directly to the Secured Party (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral). Upon the occurrence of a Default, the Debtor hereby
appoints the Secured Party as the Debtor's attorney-in-fact and in the Debtor's
or in the Secured Party's name to endorse any check or draft representing any
such payment and to execute any proof of claim, subrogation receipt and any
other document required by such insurance company as a condition to or otherwise
in connection with such payment, and, upon the occurrence of a Default, to
cancel, assign or surrender any such policies. All such sums received by the
Secured Party shall be applied by the Secured Party in satisfaction of the
Secured Obligations (subject, however, to the rights of any holders of superior
liens or security interests relating to the Collateral) or, to the extent that
such sums represent unearned premiums in respect of any policy of insurance on
the Collateral refunded by reason of cancellation, toward payment for similar
insurance protecting the respective interests of the Debtor and the Secured
Party, or as otherwise required by applicable law, and to the extent not so
applied shall be paid over to the Debtor (subject, however, to the rights of any
holders of superior liens or security interests relating to the Collateral).

7.       FIXTURES.

                  It is the intent of the Debtor and the Secured Party that none
of the Collateral shall be regarded as fixtures, as that term is used or defined
in Article 9 of the Uniform Commercial Code, and the Debtor represents and
warrants that it has not made and is not bound by any lease or other agreement
which is inconsistent with such intent. Nevertheless, if the Collateral or any
part thereof is or is to become attached or affixed to any real estate, the
Debtor will, upon request, use reasonable efforts to furnish the Secured Party
with a disclaimer or subordination in form satisfactory to the Secured Party of
its interests in the Collateral from all persons having an interest in the real
estate to which the Collateral is attached or affixed, together with the names
and addresses of the record owners of, and all other persons having an interest
in, and a general description of, such real estate.

8.       COLLECTIONS.

                  In the event of the occurrence of any Default (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral), the Debtor will immediately upon receipt of all
checks, drafts, cash or other remittances in payment of any of its accounts,
accounts receivable, contract rights or general intangibles constituting part of
the Collateral, or in payment for any Collateral sold, transferred, leased or
otherwise disposed of, or in payment or on account of its accounts, accounts
receivable, contracts, contract rights, notes, drafts, acceptances, general
intangibles, choses in

                                       4
<PAGE>

action and all other forms of obligations relating to any of the Collateral so
sold, transferred or otherwise disposed of, deliver any such items to the
Secured Party accompanied by a remittance report in form supplied or approved by
the Secured Party, such items to be delivered to the Secured Party in the same
form received, endorsed or otherwise assigned by the Debtor where necessary to
permit collection of such items and, regardless of the form of such endorsement,
the Debtor hereby waives presentment, demand, notice of dishonor, protest,
notice of protest and all other notices with respect thereto. All such
remittances (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral) shall be applied and credited by
the Secured Party first to satisfaction of the Secured Obligations or as
otherwise required by applicable law, and to the extent not so credited or
applied, shall be paid over to the Debtor.

9.       RIGHTS AND REMEDIES ON DEFAULT.

                  In the event of the occurrence of any Default (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral), the Secured Party shall at any time thereafter have
the right, with or without notice to the Debtor, as to any or all of the
Collateral, by any available judicial procedure, or without judicial process, to
take possession of the Collateral and without liability for trespass to enter
any premises where the Collateral may be located for the purpose of taking
possession of or removing the Collateral, and, generally, to exercise any and
all rights afforded to a secured party under the applicable Uniform Commercial
Code or other applicable law. Without limiting the generality of the foregoing,
the Debtor agrees that in the event of any occurrence of a Default, the Secured
Party shall have the right to sell, lease, or otherwise dispose of all or any
part of the Collateral, whether in its then condition or after further
preparation or processing, either at public or private sale or at any broker's
board, in lots or in bulk, for cash or for credit, with or without warranties or
representations, and upon such terms and conditions, all as the Secured Party in
its sole discretion may deem advisable, and it shall have the right to purchase
at any such sale; and, if any Collateral shall require rebuilding, repairing,
maintenance, preparation, or is in process or other unfinished state, the
Secured Party shall have the right, at its option, to do such rebuilding,
repairing, preparation, processing or completion of manufacturing, for the
purpose of putting the Collateral in such saleable or disposable form as it
shall deem appropriate. At the Secured Party's request (subject, however, to the
rights of any holders of superior liens or security interests relating to the
Collateral), the Debtor shall assemble the Collateral and make it available to
the Secured Party at places which the Secured Party shall reasonably select,
whether at the Debtor's premises or elsewhere, and make available to the Secured
Party, without rent, all of the Debtor's premises and facilities for the purpose
of the Secured Party's taking possession of, removing or putting the Collateral
in saleable or disposable form. The proceeds of any such sale, lease or other
disposition of the Collateral (subject, however, to the rights of any holders of
superior liens or security interests relating to the Collateral) shall be
applied first, to the expenses of retaking, holding, storing, processing and
preparing for sale, selling, and the like, and to the reasonable attorneys' fees
and legal expenses incurred by the Secured Party, and then to satisfaction of
the Secured Obligations, and to the payment of any other amounts required by
applicable law, after which the Secured Party shall account to the Debtor for
any surplus proceeds. If, upon the sale, lease or other disposition of the
Collateral, the proceeds thereof are insufficient to pay all amounts to which
the Secured Party is legally entitled, the Debtor will be liable for the
deficiency, together with interest thereon, to the extent permitted by
applicable law, at the rate, if any, prescribed in the Notes, and the reasonable
fees of any attorneys employed by the Secured Party to collect such deficiency.
To the extent permitted by applicable law, the Debtor waives all claims, damages
and demands against the Secured Party arising out of the repossession, removal,
retention or sale of the Collateral, except for such claims, damages and demands
premised on the gross negligence or willful malfeasance of the Secured Party.

10.      NOTIFICATION TO ACCOUNT DEBTORS AND OTHER OBLIGORS.

                  In the event of the occurrence of any Default, the Debtor
shall (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral), at the request of the

                                       5
<PAGE>

Secured Party, notify account debtors on accounts, accounts receivable, chattel
papers and general intangibles of the Debtor and obligors on instruments for
which the Debtor is an obligee, of the security interest of the Secured Party in
any account, account receivable, chattel paper, general intangible or instrument
and that payment thereof is to be made directly to the Secured Party or to any
financial institution designated by the Secured Party as the Secured Party's
agent therefor, and the Secured Party may itself (subject, however, to the
rights of any holders of superior liens or security interests relating to the
Collateral), if a Default shall have occurred, without notice to or demand upon
the Debtor, so notify account debtors and obligors. After the making of such a
request or the giving of any such notification, the Debtor shall (subject,
however, to the rights of any holders of superior liens or security interests
relating to the Collateral) hold any proceeds of collection of accounts,
accounts receivable, chattel paper, general intangibles and instruments received
by the Debtor as trustee for the Secured Party without commingling the same with
other funds of the Debtor and shall promptly turn the same over to the Secured
Party in the identical form received, together with any necessary endorsements
or assignments. The Secured Party shall (subject, however, to the rights of any
holders of superior liens or security interests relating to the Collateral)
apply the proceeds of collection of accounts, accounts receivable, chattel
paper, general intangibles and instruments received by the Secured Party to the
Secured Obligations, such proceeds to be immediately entered after final payment
in cash or solvent credits of the items giving rise to them.

11.      COSTS AND EXPENSES.

                  Any and all fees, costs and expenses, of whatever kind or
nature, including the reasonable attorneys' fees and legal expenses incurred by
the Secured Party, in connection with the preparation of this Agreement and all
other documents relating hereto and the consummation of this transaction, the
filing or recording of financing statements and other documents (including all
taxes in connection therewith) in public offices, the payment or discharge of
any taxes, insurance premiums, encumbrances or otherwise protecting, maintaining
or preserving the Collateral, or the enforcing, foreclosing, retaking, holding,
storing, processing, selling or otherwise realizing upon the Collateral and the
Secured Party's security interest therein, whether through judicial proceedings
or otherwise, or in defending or prosecuting any actions or proceedings arising
out of or related to the transaction to which this Agreement relates, shall be
borne and paid by the Debtor on demand by the Secured Party and until so paid
shall be added to the principal amount of the Secured Obligations and shall bear
interest at the rate prescribed in the Note and shall be secured by the
Collateral.

12.      POWER OF ATTORNEY.

                  Upon the occurrence of a Default, the Debtor authorizes the
Secured Party and does hereby make, constitute and appoint the Secured Party,
and any officer or agent of the Secured Party, with full power of substitution,
as the Debtor's true and lawful attorney-in-fact coupled with an interest, with
power, in its own name or in the name of Debtor, upon the occurrence of a
Default (subject, however, to the rights of any holders of superior liens or
security interests relating to the Collateral) to endorse any notes, checks,
drafts, money orders, or other instruments of payment (including payments
payable under or in respect of any policy of insurance) in respect of the
Collateral that may come into possession of the Secured Party; to sign and
endorse any invoice, freight or express bill, bill of lading, storage or
warehouse receipts, drafts against debtors, assignments, verifications and
notices in connection with accounts, and other documents relating to Collateral;
to pay or discharge taxes, liens, security interests or other encumbrances at
any time levied or placed on or threatened against the Collateral; to demand,
collect, receipt for, compromise, settle and sue for monies due in respect of
the Collateral; and, generally, to do, at the Secured Party's option and at the
Debtor's expense, at any time, or from time to time, all acts and things which
the Secured Party deems reasonably necessary to protect, preserve and realize
upon the Collateral and the Secured Party's security interest therein in order
to effect the intent of this Agreement and of the Notes all as fully and
effectually as the Debtor might or could do; and the Debtor hereby ratifies all
that said attorney shall lawfully do or cause to be done by virtue hereof. This
power of attorney

                                       6
<PAGE>

shall be irrevocable for the term of this Agreement and thereafter as long as
any of the Secured Obligations shall be outstanding.
