and its officers, directors and stockholders necessary for (a) the authorization
of this Agreement and the other Loan Documents to which it is a party; and
(b) the performance of all obligations of Borrower hereunder and thereunder have

proposed to be conducted. No orders, permissions, consents, approvals or
authorizations of any Governmental Authority are required to be obtained, and no

duty occurred with respect to any such Plan for which Borrower has material
liability. No reportable event within the meaning of ERISA has occurred and is

Compliance Regarding Hazardous Substances. Borrower has complied, and will
comply and cause all occupants of the Property to comply, with all current and
future laws, regulations and ordinances or other requirements of any
Governmental Authority relating to or imposing liability or standards of conduct
concerning protection of health or the environment or Hazardous Substances
(“Environmental Laws”). Borrower shall promptly, at Borrower’s sole cost and
expense, take all reasonable actions with respect to any Hazardous Substances or
other environmental condition at, on, or under the Property necessary to
(a) comply with all applicable Environmental Laws; (b) allow continued use,
occupation or operation of the Property; or (c) maintain the fair market value
of the Property. Borrower acknowledges that Hazardous Substances may permanently
and materially impair the value and use of the Property. Bank acknowledges the
matters described in Schedule 13.2, which shall not constitute an Event of
Default under this Agreement.

Notices Regarding Hazardous Substances. Until full repayment of the Loan,
Borrower will promptly notify the Bank in writing if it knows, suspects or
believes there may be any Hazardous Substance in or around the Property, or in
the soil, groundwater or soil vapor on or under the Property, or that Borrower
or the Property may be subject to any threatened or pending investigation by any
Governmental Authority under any current or future law, regulation or ordinance
pertaining to any Hazardous Substance, other than those matters described on
Schedule 13.2.

Site Visits, Observations and Testing. The Bank and its agents and
representatives will have the right at any reasonable time, after giving
reasonable notice to Borrower, to enter and visit the Property and any other
locations where any personal property collateral securing this Agreement is
located, for the purposes of observing the Property and the personal property
collateral, taking and removing environmental samples, and conducting tests on
any part of the Property. Borrower shall reimburse the Bank on demand for the
costs of any such environmental investigation and testing, for up to one time
during each 12-month period of the Loan. The Bank will make reasonable efforts
during any site visit, observation or testing conducted pursuant this paragraph
to avoid interfering with Borrower’s use of the Property and the personal
property collateral. The Bank is under no duty, however, to visit or observe the
Property or the personal property collateral or to conduct tests, and any such
acts by the Bank will be solely for the purposes of protecting the Bank’s
security and preserving the Bank’s rights under this Agreement. No site visit,
observation or testing or any report or findings made as a result thereof
(“Environmental Report”) (i) will result in a waiver of any default of Borrower;
(ii) impose any liability on the Bank; or (iii) be a representation or warranty
of any kind regarding the Property or the personal property collateral
(including its condition or value or compliance with any laws) or the
Environmental Report (including its accuracy or completeness). In the event the
Bank has a duty or obligation under applicable laws, regulations or other
requirements to disclose an Environmental Report to Borrower or any other party,
Borrower authorizes the Bank to make such a disclosure. The Bank may also
disclose an Environmental Report to any regulatory authority, and to any other
parties as necessary or appropriate in the Bank’s judgment. Borrower further
understands and agrees that any Environmental Report or other information
regarding a site visit, observation or testing that is disclosed to Borrower by
the Bank or its agents and representatives is to be evaluated (including any
reporting or other disclosure obligations of Borrower) by Borrower without
advice or assistance from the Bank.

DEFAULT

The occurrence of any one or more of the following events shall constitute an
event of default (an “Event of Default”) under this Agreement:

Notes within five (5) business days after the date when due.

together, to pay when due any Indebtedness aggregating in excess of One Hundred
Thousand Dollars ($100,000), subject to any permitted grace or cure period; or
the default by Borrower or any Guarantor, whether separately or together, in the
performance of any term, provision or condition contained in any agreement or
agreements under which any such Indebtedness was created or is governed (or the
occurrence of any other event or existence of any other condition) the effect of
which is to cause, or permit the holder, or holders of such Indebtedness to
cause such Indebtedness to become due prior to its stated maturity, subject to
any permitted grace or cure period; or any such Indebtedness of Borrower or any
Guarantor, whether separately or together, is declared to be due and payable, or
required to be prepaid, or repurchased (other than by a regularly scheduled

acquiesces in, the appointment of a receiver, custodian, trustee, examiner,
liquidator, or similar official for that Person, or any substantial portion of
that Person’s Property, (d) institutes any Proceeding seeking an order for
relief under the Federal bankruptcy laws as now or hereafter in effect, or
seeking to adjudicate that Person a bankrupt, or insolvent, or seeking

bankruptcy, insolvency, reorganization, or relief of debtors, or fails to file
an answer, or other pleading denying the material allegations of any such
Proceeding filed against it, (e) takes any corporate, or entity action to
authorize, or effect any of the foregoing provisions of this Section 14.6,
or (f) fails to contest in good faith any appointment, or Proceeding described
in Section 14.6.

Insolvency; Involuntary Proceedings. Without the application, approval or
consent of the Bank, a receiver, trustee, examiner, liquidator or similar
official is appointed for Borrower or any Guarantor, whether separately or
together, or any substantial portion of that Person’s property, or a Proceeding
described in Section 14.6 is instituted against Borrower or any Guarantor,
whether separately or together, and such appointment continues undischarged, or
such Proceeding continues undismissed or unstayed for a period of sixty
(60) consecutive days.

Security Agreement; Mortgage; Guaranty; Subordination Agreement. If (a) any of
the Security Agreement (including the security agreement delivered by the
Guarantors in support of the Guaranty), Mortgage, Guaranty, Negative Pledge,
Collateral Assignment of Rents and Leases or Subordination Agreement ceases to
be in full legal force and effect, (b) any Guarantor is

Borrowing Base. If Borrower fails to repay the Excess Amount by the expiration
of the applicable cure period.

Lien Priority. The Bank fails to have a valid and enforceable perfected security
interest in or lien on the Collateral securing Borrower’s obligations under this
Agreement, or such security interest or lien fails to be prior to the rights and
interest of all other Liens except for any Liens in favor of the Bank and
Permitted Liens.

Judgments. Borrower or any Guarantor, whether separately or together, fails
(a) within thirty (30) days to pay, bond or otherwise discharge one or more
monetary judgments entered against such Person or orders for the payment of
money in excess of One Hundred Thousand Dollars ($100,000) in the aggregate, or
(b) to pay, bond or otherwise discharge one or more nonmonetary judgments
entered against that Person or orders which, individually or in the aggregate,
could reasonably be expected to have a Material Adverse Effect, which
judgment(s), in any such case, is/are not stayed on appeal or otherwise being
contested in good faith by an appropriate Proceeding.

Material Adverse Change. A material adverse change occurs, or is reasonably
likely to occur, in the business condition (financial or otherwise), operations,

REMEDIES

If an Event of Default occurs and is continuing, the Bank may:

Acceleration. Declare all amounts previously advanced to Borrower under this
Agreement and the Notes, and all interest accrued and unpaid thereon, and all
other debts, liabilities and obligations evidenced or secured by this Agreement,
the Notes or the other Loan Documents, to be immediately due and payable without
presentment, demand, protest or further notice of any kind (all of which hereby
are expressly waived), which, unless otherwise provided in the applicable Loan
Document, shall thereupon bear interest at five percent (5.0%) over the rate
specified for the Loan in this Agreement or the maximum rate of interest allowed
by applicable law, whichever lower, and the Bank may thereupon institute
Proceedings to collect the same.

Enforcement. Exercise its rights and remedies under the Notes and any of the
other Loan Documents, including the Security Agreement (including the security
agreement delivered by the Guarantors in support of the Guaranty), Mortgage,
Guaranty, Negative Pledge, Collateral Assignment of Rents and Leases and
Subordination Agreement.

ENFORCING THIS AGREEMENT; MISCELLANEOUS

Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of Florida. To the extent that the Bank has greater rights or
remedies under federal law, whether as a national bank or otherwise, this
paragraph shall not be deemed to deprive the Bank of such rights and remedies as
may be available under federal law.

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

Successors and Assigns. This Agreement is binding on Borrower and the Bank’s
successors and assignees. Borrower agrees that it may not assign this Agreement
without the Bank’s prior written consent.

Cross Collateralization/Cross Default. Borrower hereby agrees that an occurrence
of an Event of Default(s) under this Agreement shall be deemed a default under
any other loan or loan commitment between Borrower and the Bank and that the
security for this Loan provided for in Section 6 hereof shall serve as
collateral and security for any other loan or loan commitment between Borrower
and the Bank.

Payments on Subordinated Debt. Borrower may utilize the proceeds of the Notes to
pay principal outstanding under the Subordinated Notes, in accordance with the
terms of the Subordination Agreement.

Attorneys’ Fees. Borrower shall reimburse the Bank for any reasonable costs and
attorneys’ fees incurred by the Bank in connection with the enforcement or
preservation of any rights or remedies under this Agreement, the Notes and the
other Loan Documents, and in connection with any amendment, waiver, “workout” or
restructuring to any of the foregoing. In the event of a lawsuit or arbitration
proceeding, the prevailing party is entitled to recover costs and reasonable
attorneys’ fees incurred in connection with the lawsuit or arbitration
proceeding, as determined by the court or arbitrator. In the event that any case
is commenced by or against Borrower under the Bankruptcy Code (Title 11, United
States Code) or any similar or successor statute, the Bank is entitled to
recover costs and reasonable attorneys’ fees incurred by the Bank related to the
preservation, protection or enforcement of any rights of the Bank in such a
case.

Set-Off. In addition to any rights and remedies of the Bank provided by law,
upon the occurrence and during the continuance of any Event of Default under
this Agreement, the Bank is authorized, at any time, to set off and apply any
and all deposits of Borrower held by the Bank against any and all Indebtedness
owing to the Bank. The set-off may be made irrespective of whether or not the
Bank shall have made demand under this Agreement and may be made without prior
notice to Borrower or any other party, any such notice being waived by Borrower
(on its own behalf and on behalf of each Guarantor) to the fullest extent
permitted by law, except to the extent notice is required as a component of the
Event of Default. The Bank agrees promptly to notify Borrower after any such
set-off and application; provided, however, that the failure to give such notice
shall not affect the validity of such set-off and application.

Indemnification. Borrower agrees to indemnify the Bank, its officers, directors,
employees, representatives and agents from and hold each of them harmless
against any and all losses, liabilities, claims, damages or expenses incurred by
any of them as a result of, or arising out of, or in any way related to, or by
reason of, any investigation, litigation, or other Proceeding (whether or not
the Bank is a party thereto) related to the entering into and/or performance of
any of the Loan Documents, or the use of proceeds of the Loan, or the
consummation of any other transactions contemplated in any of the Loan
Documents, including the reasonable fees and disbursements of counsel incurred
in connection with any such investigation, litigation or other Proceeding (but
excluding any such losses, liabilities, claims, damages or expenses to the
extent incurred by reason of gross negligence or willful misconduct on the part
of the Person to be indemnified). The provisions of this section survive the
repayment of the Notes and the termination of this Agreement or any of the other
Loan Documents for the applicable period of limitations imposed by law.

Documentary Stamp Tax. Borrower agrees to defend, indemnify and hold the Bank
harmless from and against any and all liability for documentary excise taxes and
intangible taxes (together with all interest, penalties, costs and reasonable
attorneys’ fees incurred in connection therewith) that at any time may be
levied, assessed, or imposed by the State of Florida or any other Governmental
Authority (a) upon the Notes, Security Agreement, Mortgage or any of the other
Loan Documents, (b) upon any amendment, extension, or renewal of any of the
foregoing, or

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

(c) upon the Bank by virtue of owning or holding any of the foregoing documents
or instruments; all of which shall be secured by the security interest, or other
Lien granted by the Security Agreement or Mortgage, as applicable. The
provisions of this survive the repayment of the Notes and the termination of
this Agreement, or any of the other Loan Documents for so long as any claim may
be asserted by the State of Florida or any other Governmental Authority.

Cumulative Remedies. Each and every right, remedy and power granted to the Bank
under this Agreement and the other Loan Documents is cumulative and in addition
to any other right, remedy or power herein or therein specifically granted, now
or hereafter existing in equity, at law, by virtue of statute, by agreement or
otherwise, and may be exercised by the Bank from time to time concurrently or
independently and as often and in such order as the Bank may deem expedient.

Notices. Unless otherwise provided in this Agreement or in another agreement
between the Bank and Borrower, all notices required under this Agreement shall
be personally delivered or sent by first class mail, postage prepaid, or by
overnight courier, to the addresses on the signature page of this Agreement, or
to such other addresses as the Bank and Borrower may specify from time to time
in writing. Notices and other communications shall be effective (a) if mailed,
upon the earlier of receipt or five (5) days after deposit in the U.S. mail,
first class, postage prepaid, or (b) if hand-delivered, by courier or otherwise
(including telegram, lettergram or mailgram), when delivered.

Waiver.

The failure of the Bank (i) to insist upon or enforce strict performance of any
provision of this Agreement or any of the other Loan Documents; or (ii) to
exercise any right, power or authority under this Agreement, any of the other
Loan Documents or any right, power or remedy available to the Bank at law, shall
not be construed as a waiver, renouncement or relinquishment of the Bank’s right
to assert or rely upon that provision, right, power or authority, and that
provision, right, power or authority shall continue in full legal force and
effect without waiver, renouncement or relinquishment. No waiver by the Bank of
any provision of this Agreement or any of the other Loan Documents shall be
binding unless in writing and signed by the Bank. No waiver by the Bank of any
provision of this Agreement or any of the other Loan Documents constitutes a
waiver of any other provision of this Agreement or such Loan Document, as the
case may be, whether or not similar, nor shall any waiver constitute a
continuing waiver, unless otherwise expressly provided. Any failure or delay on
the part of the Bank in exercising any such right, remedy or power, or
abandonment or discontinuance of steps to enforce the same, does not operate as
a waiver thereof or affect the Bank’s right thereafter to exercise the same, and
any single or partial exercise of any such right, remedy or power does not
preclude any other or further exercise thereof or the exercise of any other
right, remedy or power.

The receipt by the Bank of any sum of money under this Agreement with knowledge
of the breach of any term, covenant or provision of this Agreement shall not be
deemed a waiver of such breach. No payment by Borrower or receipt by the Bank of
a lesser amount than any sum of money herein stipulated shall be deemed to be
other than on account of such stipulated sum, nor shall any endorsement or
statement on any check, or any letter accompanying any check, be deemed an
accord and satisfaction and the Bank may accept such payment or check without
prejudice to the Bank’s right to recover the balance of any payment or other
monies under this Agreement or pursue any of the remedies under this Agreement
and any of the other Loan Documents.

No advance by the Bank to Borrower under this Agreement constitutes a waiver of
any of the Borrower’s obligations under this Agreement and the Loan Documents.

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

Time. All references to time herein shall be references to Eastern Standard Time
or Eastern Daylight Time, as the case may be, unless specified otherwise. Time
is of the essence as to this Agreement, and each of the other Loan Documents,
and all of their respective provisions and obligations.

Assignment.

Borrower acknowledges that the Bank is relying solely on the financial and
managerial ability of Borrower and its principals in granting and funding the
Loan and, therefore, Borrower has no right to assign (any assignment by
operation of law shall be deemed for the purposes of this Agreement an
assignment by Borrower) any rights under this Agreement.

The Bank may, from time to time, assign in whole or in part, or issue
participation interests in and to, all of its rights and interests under this
Agreement, the Notes, Security Agreement, Mortgage, Guaranty and the other Loan
Documents. In such event, this Agreement shall continue to apply to the Loan,
the Notes, Security Agreement, Mortgage, Guaranty and the other Loan Documents.
The Bank agrees to give Borrower notice of any such assignment but the failure
of the Bank to give such notice shall not affect the validity of any such
assignment or any obligations of Borrower or any other Person under this
Agreement, the Notes, Security Agreement, Mortgage, Guaranty and the other Loan
Documents. Provided the participant or prospective participant agrees in writing
to maintain the confidentiality of disclosed information, the Bank may disclose
to any participant or prospective participant any information, data or material
in the Bank’s possession relating to Borrower, the Loan and Guarantor without
the consent of or notice to Borrower, Guarantor or any other Person. In the
event of such assignment, it shall be deemed to have been made pursuant to the
provisions of this Agreement and not to be in modification of this Agreement and
any advances made by any such assignee shall be evidenced and secured by the
Notes, Security Agreement, Mortgage, Guaranty and the other Loan Documents.

WAIVER OF JURY TRIAL

The Bank AND Borrower EACH knowingly, voluntarily and intentionally waive any
rights it may have to a trial by jury, with respect to any Proceeding based on
or arising out of this Agreement, the NOTES, or any of the Loan Documents,
including any course of conduct, course of dealings, verbal or written
statements, or actions or omissions of any party which in any way relate to the
Loan. The parties hereto have specifically discussed and negotiated this waiver
and understand the legal consequences of signing this Agreement. This waiver by
Borrower and Guarantor is a material inducement for THE Bank’s entering into
this Agreement, and THE Bank’s waiver is a material inducement for Borrower’s
acceptance of the Loan and the execution and delivery by Borrower and guarantor
of the Loan Documents to which such Person is a party. At a party’s request, the
other parties will join in asking the court in which suit is pending to try the
case and decide all issues, including issues of fact, without a jury.

Jurisdiction; Venue. The validity, construction, enforcement and interpretation
of this Agreement shall be governed by the substantive laws of the State of
Florida, without application of its conflicts of law principles, and the United
States of America. Any action, suit or proceeding arising out of this Agreement
shall be brought in the Thirteenth Judicial Circuit in and for Hillsborough
County, Florida, or in the United States District Court for the Middle District
of Florida, Tampa Division, and each party irrevocably consents to and submits
to the jurisdiction of those courts, and irrevocably waives any objection which
such party now or hereafter may have to the institution of any such suit, action
or proceeding in those courts, and further irrevocably waives any defense or
claim that such suit, action or proceeding in any such court has been brought in
an inconvenient forum or improper venue.

Headings. Section and paragraph headings are for reference only and shall not
affect the interpretation or meaning of any provisions of this Agreement.

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

Counterparts. This Agreement may be executed in as many counterparts as
necessary or convenient, and by the different parties on separate counterparts
each of which, when so executed, shall be deemed an original but all such
counterparts shall constitute but one and the same agreement.

Limitation of Interest and Other Charges. Notwithstanding any other provision
contained in this Agreement, the Bank does not intend to charge, and Borrower
shall not be required to pay, any amount of interest or other fees or charges
that is in excess of the maximum permitted by applicable law. Any payment in
excess of such maximum shall be refunded to Borrower or credited against
principal, at the option of the Bank. It is the express intent hereof that
Borrower not pay and the Bank not receive, directly or indirectly, interest in
excess of that which may be lawfully paid under applicable law including the
usury laws in force in the state of Florida.

Schedule 13.2

In preparation for the sale of its Earlysville, Virginia facility, Borrower
engaged an environmental consulting firm to survey the property for any possible
soil or groundwater contamination. This survey revealed impacts to both shallow
soils and groundwater that may have resulted from the accidental loss of
solvents by a former owner of the property. As a result, of the initial and
subsequent surveys, remaining contamination treatment costs are estimated at
$932,000. Borrower has capitalized these contamination treatment costs as an
increase to property held for sale, net, since such costs will be incurred in
preparation for the sale of the Earlysville, Virginia facility and will not
result in a carrying value in excess of the estimated fair value less cost to
sell. Costs incurred during the year ended January 31, 2010 totaled $153,000 and
costs incurred during the year ended January 31, 2009 totaled $110,000.
