the lesser of (i) the Revolving Credit Committed Amount or (ii) the Borrowing Base.

(b) Subject to the provisions of this
Agreement, the Borrowers may request Advances during the Revolving Credit Commitment Period in accordance with the provisions of this Agreement; provided that after giving effect to the Borrowers request, the aggregate Revolver Usage would not
exceed the lesser of (i) Revolving Credit Committed Amount or (ii) the Borrowing Base.



25



---

(c) Unless sooner paid, the unpaid Revolving Loan, together with interest accrued and unpaid thereon,
and all other Obligations shall be due and payable in full on the Revolving Credit Expiration Date.

(d) If at any time the Revolver Usage
exceeds the Revolving Credit Committed Amount in effect from time to time, the Borrower shall pay such excess to the Lender ON DEMAND.

2.1.2 Procedure for Making Advances Under the Revolving Loan; Lender Protection Loans.

The Borrowers may borrow under the
Revolving Credit Facility on any Business Day. Advances under the Revolving Loan shall be deposited to a demand deposit account of a Borrower with the Lender or shall be otherwise applied as directed by the Borrowers, which direction the Lender may
require to be in writing. Not later than 10:00 a.m. (Baltimore City Time) on the date of the requested borrowing, the Borrowers shall give the Lender oral or written notice (a Loan Notice) of the amount and (if requested by the Lender)
the purpose of the requested borrowing. Any oral Loan Notice shall be confirmed in writing by the Borrowers within three (3) Business Days after the making of the requested advance under the Revolving Loan. Each Loan Notice shall be
irrevocable.

In addition, each of the Borrowers hereby irrevocably authorizes the Lender at any time and from time to time, without
further request from or notice to the Borrowers, to make Advances, and irrevocably authorizes the Lender to establish, without duplication, Reserves against the Borrowing Base, that the Lender, in its sole and absolute discretion (but, unless an
Event of Default has occurred and is continuing, after consultation with the Borrower), deems necessary or appropriate to protect the interests of the Lender under this Agreement, including, without limitation, Advances and Reserves to cover debit
balances in the Revolving Loan Account, principal of and interest on any Loan, Bank Products, Revolver Usage, Enforcement Costs and the other Obligations, all of the foregoing whether prior to, on, or after the termination of other advances under
this Agreement, and regardless of whether the outstanding principal amount of the Revolving Loan that the Lender may advance or the Lender may reserve hereunder exceeds the Revolving Credit Committed Amount or the Borrowing Base.

2.1.3 Computation of Borrowing Base.

(a) As used in this Agreement, the term Borrowing Base means at any time, an amount equal to the aggregate of (i) eighty-five percent (85%) of the amount of Eligible Receivables plus (ii) the lesser of
(A) fifty-five percent (55%) of the amount of Eligible Inventory or (B) Six Million Dollars ($6,000,000), subject to the adjustments provided in this Section 2.1, plus (iii) (A) sixty-five percent (65%) of
the amount of Eligible Fixed Assets through and including the first anniversary date, and (B) fifty-five percent (55%) of the amount of Eligible Fixed Assets, thereafter.

(b) The Borrowing Base shall be computed based on the Loan Base Report most recently delivered to and accepted by the Lender in its sole and absolute
discretion. In the event the Borrowers fail to furnish a Loan Base Report required by Section 6.1.2 (Loan Base Report), or in the event the Lender believes that a Loan Base Report is no longer accurate, the Lender may, in its sole and absolute
discretion exercised from time to time and without



26



---

limiting other rights and remedies under this Agreement, suspend the making of or limit advances under the Revolving
Loan. The amount of the Borrowing Base shall be subject to reduction by the amount of Reserves applicable from time to time and by the amount of any Receivable or any Inventory that was included in the Borrowing Base but that the Lender determines
fails to meet the respective criteria applicable from time to time for Eligible Receivables or Eligible Inventory.

(c) If at any time the
aggregate Revolver Usage exceeds the Borrowing Base, a borrowing base deficiency (Borrowing Base Deficiency) shall exist. Each time a Borrowing Base Deficiency exists, the Borrowers at the sole and absolute discretion of the Lender
exercised from time to time shall pay the Borrowing Base Deficiency ON DEMAND to Lender.

(d) Without implying any limitation on the
Lenders discretion with respect to the Borrowing Base, the criteria for Eligible Receivables and for Eligible Inventory contained in the respective definitions of Eligible Receivables and of Eligible Inventory are in part based upon the
business operations of the Borrowers existing on or about the Closing Date and upon information and records furnished to the Lender by the Borrowers. If at any time or from time to time hereafter, the business operations of the Borrowers change or
such information and records furnished to the Lender is incorrect or misleading, the Lender in its discretion, may at any time and from time to time during the duration of this Agreement change such criteria or add new criteria. The Lender may
communicate such changed or additional criteria to the Borrowers from time to time either orally or in writing.

Note shall be dated as of the Closing Date, shall be payable to the order of the Lender at the times provided in the Revolving Credit Note, and shall be in the principal amount of the Revolving Credit Committed Amount. Each of the Borrowers
acknowledges and agrees that, if the outstanding principal balance of the Revolving Loan outstanding from time to time exceeds the face amount of the Revolving Credit Note, the excess shall bear interest at the rates provided from time to time for
advances under the Revolving Loan evidenced by the Revolving Credit Note and shall be payable, with accrued interest, ON DEMAND. The Revolving Credit Note shall not operate as a novation of any of the Obligations or nullify, discharge, or release
any such Obligations or the continuing contractual relationship of the parties hereto in accordance with the provisions of this Agreement.

2.2.1Acquisition Line Commitment.

Subject to and upon the provisions of this Agreement, the Lender establishes a credit line in the maximum principal amount of the Acquisition Line Committed Amount in

---

favor of the Borrowers. The aggregate of all advances under the Acquisition Line Facility is sometimes referred to in
this Agreement collectively as the Acquisition Line. The obligation of the Lender to make an advance under the Acquisition Line is herein called its Acquisition Line Commitment.

During the Acquisition Line Commitment Period, the Borrowers may request advances under the Acquisition Line Facility in accordance with the provisions
of this Agreement; provided that after giving effect to the Borrowers request (a) the outstanding principal balance of the Acquisition Line would not exceed the Acquisition Line Commitment; and (b) the aggregate outstanding principal
balance of the Acquisition Line Term Advances would not exceed $5,000,000. Amounts repaid on the Acquisition Line may be reborrowed in accordance with this Section 2.2 (The Acquisition Line Facility).

2.2.2 Procedure for Making Advances Under the Acquisition Line.

The Borrowers may borrow under the Acquisition Line Facility on any Business Day. The Borrowers shall give the Lender written notice (a Acquisition Line Notice) at least fifteen (15) Business Days
prior to the date on which the Borrowers desire an Acquisition Line Advance. The Lender shall have no obligation to make an Acquisition Line Advance unless and until the Lender is satisfied that the Acquisition Line Advance will be solely for a
Permitted Acquisition and the other terms and conditions for advances under this Agreement have been met.

2.2.3 Acquisition Line
Notes.

The obligation of the Borrowers to pay each Acquisition Line Advance with interest shall be evidenced by an Acquisition Line
Term Note or by the Acquisition Line Revolving Note (each, as from time to time extended, amended, restated, supplemented or otherwise modified, an Acquisition Line Note; collectively with each other Acquisition Line Note, the
Acquisition Line Notes). The Borrowers obligation to repay an Acquisition Line Term Advance shall be evidenced by a promissory note in substantially the form of EXHIBIT A-2 attached hereto and made a part hereof,
with appropriate insertions (each, as from time to time extended, amended, restated, supplemented or otherwise modified, a Acquisition Line Term Note; collectively with each other Acquisition Line Term Note, the Acquisition Line
Term Notes). To the extent an Acquisition Line Advance is not evidenced by an Acquisition Line Term Note, it shall be evidenced by a promissory note (as from time to time extended, amended, restated, supplemented or otherwise modified, the
Acquisition Line Revolving Note) , in the amount of the Acquisition Line Commitment, in substantially in the form of EXHIBIT A-3. The Acquisition Line Notes shall not operate as a novation of any of the Obligations or
nullify, discharge, or release any such Obligations or the continuing contractual relationship of the parties hereto in accordance with the provisions of this Agreement.

2.2.4 Acquisition Line Term Payments.

The Borrowers shall make installment payments of principal
(each an Acquisition Line Term Payment and collectively the Acquisition Line Term Payments) on each on each Acquisition Line Term Advance commencing on the first day of the first month after the Acquisition Line Term Advance
is made. Each Acquisition Line Term Payment shall be in an amount equal to 1/24th of that portion of the amount of the Acquisition Line Term Advance.

2.2.5 Acquisition Line Maturity.

If not sooner paid, each Acquisition Line Term Advance shall mature and shall be due and payable, together with interest accrued and unpaid thereon, on
the due date of its twenty-fourth Acquisition Line Term Payment. Notwithstanding the foregoing, if not sooner paid, all Acquisition Line Advances shall mature and shall be due and payable, together with interest accrued and unpaid thereon, on the
Revolving Credit Termination Date.

2.2.6 Mandatory Prepayments of Acquisition Line.

The Borrowers shall make mandatory prepayments (each a Acquisition Line Mandatory Prepayment and collectively the Acquisition Line
Mandatory Prepayments) of the Acquisition Line Term Advances to the Lender annually. Each Acquisition Line Mandatory Prepayment shall be in the amount of the Excess Cash Flow for the then preceding fiscal year and shall be payable on the date
the Borrowers furnish to the Lender the annual financial statements referred to in Section 6.1.1 (Financial Statements). Each Partial Acquisition Line Mandatory Prepayment first shall be applied to the first Acquisition Line Term Note to be
executed and delivered until that Acquisition Line Term Note is paid in full, and then to the subsequent Acquisition Line Term Notes sequentially in the order of their respective dates until they each successively have been paid in full, with
Partial Acquisition Line Optional Prepayments being applied against the Acquisition Line Term Payments under the applicable Acquisition Line Term Notes in the inverse order of their maturity until all outstanding Acquisition Line Term Advances have
been paid in full.

2.2.7 Optional Prepayments of Acquisition Line.

The Borrowers may, at its option, at any time and from time to time prepay (each a Acquisition Line Optional Prepayment and collectively the
Acquisition Line Optional Prepayments) the Acquisition Line, in whole or in part without premium or penalty, upon five (5) Business Days prior written notice, specifying the date and amount of prepayment. The amount to be so
prepaid, together with interest accrued thereon to date of prepayment if the amount is intended as a prepayment of the Acquisition Line in whole, shall be paid by the Borrowers to the Lender on the date specified for such prepayment. Each Partial
Acquisition Line Optional Prepayment shall be applied, first, to the first Acquisition Line Term Note to be executed and delivered until that Acquisition Line Term Note is paid in full, and then to the subsequent Acquisition Line Term
Notes sequentially in the order of their respective dates until they each successively have been paid in full, with Partial Acquisition Line Optional Prepayments being applied against the Acquisition Line Term Payments under the applicable
Acquisition Line Term Note in the inverse order of their maturity until all outstanding Acquisition Line Term Advances have been paid in full; and, finally to the Acquisition Line Revolving Note.

Section 2.3 The Letter of Credit Facility.

2.3.1 Letters of Credit.

Subject to and upon the provisions of this Agreement, and as a part of the
Revolving Credit Commitment, each of the Borrowers, upon the prior approval of the Lender, may obtain letters of credit (as the same may from time to time be amended, supplemented or otherwise modified, each a Letter of Credit and
collectively the Letters of Credit) from the Lender from time to time from the Closing Date until the Business Day preceding the Revolving



30



---

Credit Termination Date. The Borrowers will not be entitled to obtain a Letter of Credit unless (a) after giving
effect to the request, the aggregate Revolver Usage would not exceed the lesser of (i) the Revolving Credit Committed Amount, or (ii) the most current Borrowing Base and (b) the sum of the aggregate face amount of the then outstanding
Letters of Credit (including the face amount of the requested Letter of Credit) does not exceed Two Million Dollars ($2,000,000).

2.3.2
Letter of Credit Fees.

Prior to or simultaneously with the opening of each Letter of Credit, the Borrowers shall pay to the Lender,
a letter of credit fee (each a Letter of Credit Fee and collectively the Letter of Credit Fees) in an amount equal to the Applicable Margin set forth in Section 2.4.1(c) for Letter of Credit Fees applied to the face
amount of the Letter of Credit. The Letter of Credit Fee shall be an annual amount and prorated for that portion of a year the Letter of Credit is issued if less than a full year. The Letter of Credit Fees shall be paid upon the opening of each
Letter of Credit and upon each anniversary thereof, if any. In addition, the Borrowers shall pay to the Lender, for its own account, any and all of its standard additional issuance, negotiation, processing, transfer or other fees to the extent and
as and when required by the provisions of any Letter of Credit Agreement. All such additional fees are included in and are a part of the Fees payable by the Borrowers under the provisions of this Agreement and are for the sole and
exclusive benefit of the Lender and are a part of the Obligations. Subsequent to an Event of Default that remains continuing, the Letter of Credit Fee shall be increased by a rate of 200 basis points per annum.

2.3.3 Terms of Letters of Credit; Post-Expiration Date Letters of Credit.

Each Letter of Credit shall (a) be opened pursuant to a Letter of Credit Agreement and (b) expire on a date not later than the Business Day
preceding the Revolving Credit Expiration Date; provided, however, if any Letter of Credit does have an expiration date later than the Business Day preceding the Revolving Credit Termination Date (each a Post-Expiration Date Letter of
Credit and collectively, the Post-Expiration Date Letters of Credit), effective as of the Business Day preceding the Revolving Credit Termination Date and without prior notice to or the consent of the Borrowers, the Lender shall
make advances under the Revolving Loan for the account of the Borrowers in the aggregate face amount of all such Letters of Credit. The Lender shall deposit the proceeds of such advances into one or more non-interest bearing accounts with and in the
name of the Lender and over which the Lender alone shall have exclusive power of access and withdrawal (collectively, the Letter of Credit Cash Collateral Account). The Letter of Credit Cash Collateral Account is to be held by the Lender
as additional collateral and security for any Letter of Credit Obligations relating to the Post-Expiration Date Letters of Credit. The Borrowers hereby assign, pledge, grant and set over to the Lender a first priority security interest in, and Lien
on, all of the funds on deposit in the Letter of Credit Cash Collateral Account, together with any and all proceeds (cash and non-cash) and products thereof as additional collateral and security for the Letter of Credit Obligations relating to the
Post-Expiration Date Letters of Credit. The Borrowers acknowledge and agree that the Lender shall be entitled to fund any draw or draft on any Post-Expiration Date Letter of Credit from the monies on deposit in the Letter of Credit Cash Collateral
Account without notice to or consent of the Borrowers or the Lender. The Borrowers further acknowledge and agree that the Lenders election to fund any draw or draft on any Post-Expiration Date Letter of Credit from the Letter of Credit Cash
Collateral shall in no way limit, impair, lessen, reduce, release or



31



---

otherwise adversely affect the Borrowers obligation to pay any Letter of Credit Obligations under or relating to
the Post-Expiration Date Letters of Credit. At such time as all Post-Expiration Date Letters of Credit have expired and all Letter of Credit Obligations relating to the Post-Expiration Date Letters of Credit have been paid in full, the Lender agrees
to apply the amount of any remaining funds on deposit in the Letter of Credit Cash Collateral Account to the then unpaid balance of the Obligations under the Revolving Credit Facility in such order and manner as the Lender shall determine in its
sole and absolute discretion in accordance with the provisions of this Agreement and any excess shall be paid to the Borrowers unless otherwise required by applicable Laws.

The aggregate face amount of all Letters of Credit at any one time outstanding and issued by the Lender pursuant to the provisions of this Agreement,
including, without limitation, any and all Post-Expiration Date Letters of Credit, plus the amount of any unpaid Letter of Credit Fees accrued or scheduled to accrue thereon, and less the aggregate amount of all drafts issued under or purporting to
have been issued under such Letters of Credit that have been paid by the Lender and for which the Lender has been reimbursed by the Borrowers in full in accordance with Section 2.3.5 below and the Letter of Credit Agreements, and for which the
Lender has no further obligation or commitment to restore all or any portion of the amounts drawn and reimbursed, is herein called the Outstanding Letter of Credit Obligations.

2.3.4 Procedures for Letters of Credit.

The Borrowers shall give the Lender written notice at least five (5) Business Days prior to the date on which the Borrower desires the Lender to issue a Letter of Credit. Such notice shall be accompanied by a duly executed Letter of
Credit Agreement specifying, among other things: (a) the name and address of the intended beneficiary of the Letter of Credit, (b) the requested face amount of the Letter of Credit, (c) whether the Letter of Credit is to be revocable
or irrevocable, (d) the Business Day on which the Letter of Credit is to be opened and the date on which the Letter of Credit is to expire, (e) the terms of payment of any draft or drafts which may be drawn under the Letter of Credit, and
(f) any other terms or provisions the Borrowers desire to be contained in the Letter of Credit. Such notice shall also be accompanied by such other information, certificates, confirmations, and other items as the Lender may require to assure
that the Letter of Credit is to be issued in accordance with the provisions of this Agreement and a Letter of Credit Agreement. In the event of any conflict between the provisions of this Agreement and the provisions of a Letter of Credit Agreement,
the provisions of this Agreement shall prevail and control unless otherwise expressly provided in the Letter of Credit Agreement. Upon (x) receipt of such notice, (y) payment of all Letter of Credit Fees and all other Fees payable in
connection with the issuance of such Letter of Credit, and (z) receipt of a duly executed Letter of Credit Agreement, the Lender shall process such notice and Letter of Credit Agreement in accordance with its customary procedures and open such
Letter of Credit on the Business Day specified in such notice.

2.3.5 Payments of Letters of Credit.

The Borrowers hereby promise to pay to the Lender, ON DEMAND and in United States Dollars, the following which are herein collectively referred to as the
Current Letter of Credit Obligations:



32



---

(a) the amount which the Lender has paid or will be required to pay under each draft or draw on a Letter
of Credit, whether such demand be in advance of the Lenders payment or for reimbursement for such payment;

(b) any and all
reasonable charges and expenses which the Lender may pay or incur relative to the Letter of Credit and/or such draws or drafts; and

(c)
interest on the amounts described in (a) and (b) not paid by the Borrowers as and when due and payable under the provisions of (a) and (b) above from the day the same are due and payable until paid in full at a rate per annum
equal to the then current highest rate of interest on the Revolving Loan.

In addition, the Borrowers hereby promise to pay any and all
other Letter of Credit Obligations as and when due and payable in accordance with the provisions of this Agreement and the Letter of Credit Agreements. The obligation of the Borrowers to pay Current Letter of Credit Obligations and all other Letter
of Credit Obligations shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrowers or any other account party may have or have had against the beneficiary
of such Letter of Credit, the Lender, or any other Person (excluding, however, any defense based on the failure of any draft or draw to conform to the terms of such Letter of Credit), any draft or other document proving to be forged, fraudulent or
invalid, or the legality, validity, regularity or enforceability of such Letter of Credit, any draft or other documents presented with any draft, any Letter of Credit Agreement, this Agreement, or any of the other Financing Documents, all whether or
not the Lender had actual or constructive knowledge of the same, and irrespective of any Collateral, security or guarantee therefor or right of offset with respect thereto and irrespective of any other circumstances whatsoever which constitutes, or
might be construed to constitute, an equitable or legal discharge of the Borrowers for any Letter of Credit Obligations, in bankruptcy or otherwise; provided, however, that the Borrowers shall not be obligated to reimburse the Lender
for any wrongful payment under such Letter of Credit made as a result of the Lenders gross negligence or willful misconduct. The obligation of the Borrowers to pay the Letter of Credit Obligations shall not be conditioned or contingent upon
the pursuit by the Lender or any other Person at any time of any right or remedy against any Person which may be or become liable in respect of all or any part of such obligation or against any Collateral, security or guarantee therefor or right of
offset with respect thereto.

The Letter of Credit Obligations shall continue to be effective, or be reinstated, as the case may be, if at
any time payment of all or any portion of the Letter of Credit Obligations is rescinded or must otherwise be restored or returned by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Person, or upon or as
a result of the appointment of a receiver, intervenor, or conservator of, or trustee or similar officer for, any Person, or any substantial part of such Persons property, all as though such payments had not been made.

2.3.6 Change in Law; Increased Cost.

If any change in any law or regulation or in the interpretation thereof by any court or other Governmental Authority charged with the administration thereof shall either (a) impose, modify or deem applicable any reserve, special
deposit or similar requirement against Letters of Credit issued by the Lender, or (b) impose on the Lender any other condition regarding this



33



---

Agreement or any Letter of Credit, and the result of any event referred to in clauses (a) or (b) above shall be
to increase the cost to the Lender of issuing, maintaining or extending the Letter of Credit or the cost to the Lender of funding any obligation under or in connection with the Letter of Credit (which increase in cost shall be the result of the
Lenders reasonable allocation of the aggregate of such cost increases resulting from such events), then, upon demand by the Lender, the Borrowers shall immediately pay to the Lender from time to time as specified by the Lender, additional
amounts that shall be sufficient to compensate the Lender for such increased cost, together with interest on each such amount from the date demanded until payment in full thereof at a rate per annum equal to the then highest current rate of interest
on the Revolving Loan. A certificate as to such increased cost incurred by the Lender, submitted by the Lender to the Borrowers, shall be conclusive, absent manifest error.

2.3.7 General Letter of Credit Provisions.

The Borrowers hereby instruct the Lender to pay any draft complying with the terms of any Letter of Credit irrespective of any instructions of the Borrowers to the contrary. The Borrowers assume all risks of the acts and omissions of the
beneficiary and other users of any Letter of Credit except presentation of any draft and/or documents conforming to the terms of the Letter of Credit. The Lender and its respective branches, Affiliates and/or correspondents shall not be
responsible for and the Borrowers hereby indemnify and hold the Lender and its respective branches, Affiliates and/or correspondents harmless from and against all liability, loss and expense (including reasonable attorneys fees and costs)
incurred by the Lender and/or their respective branches, Affiliates and/or correspondents relative to and/or as a consequence of (a) any failure by the Borrowers to perform the agreements hereunder and under any Letter of Credit Agreement,
(b) any Letter of Credit Agreement, this Agreement, any Letter of Credit and any draft, draw and/or acceptance under or purported to be under any Letter of Credit, (c) any action taken or omitted by the Lender and/or any of its respective
branches, Affiliates and/or correspondents at the request of the Borrowers, (d) any failure or inability to perform in accordance with the terms of any Letter of Credit by reason of any control or restriction rightfully or wrongfully exercised
by any de facto or de jure Governmental Authority, group or individual asserting or exercising governmental or paramount powers, and/or (e) any consequences arising from causes beyond the control of the Lender and/or any of its
respective branches, Affiliates and/or correspondents.

Except for gross negligence or willful misconduct, the Lender and its respective
branches, Affiliates and/or correspondents, shall not be liable or responsible in any respect for any (a) error, omission, interruption or delay in transmission, dispatch or delivery of any one or more messages or advices in connection with any
Letter of Credit, whether transmitted by cable, telegraph, mail or otherwise and despite any cipher or code which may be employed, and/or (b) action, inaction or omission which may be taken or suffered by it or them in good faith or through
inadvertence in identifying or failing to identify any beneficiary or otherwise in connection with any Letter of Credit.

Any Letter of
Credit may be amended, modified or revoked only upon the receipt by the Lender from the Borrowers and the beneficiary (including any transferee and/or assignee of the original beneficiary), of a written consent and request therefor.

If any Laws, order of court and/or ruling or regulation of any Governmental Authority of the United States (or any state thereof) and/or any country
other than the United



34



---

States permits a beneficiary under a Letter of Credit to require the Lender and/or any of its respective branches,
Affiliates and/or correspondents to pay drafts under or purporting to be under a Letter of Credit after the expiration date of the Letter of Credit, the Borrowers shall reimburse the Lender, as appropriate, for any such payment pursuant to
provisions of Section 2.3.6 (Change in Law; Increased Cost).

Except as may otherwise be specifically provided in a Letter of Credit
or Letter of Credit Agreement, the laws of the State and the Uniform Customs and Practice for Documentary Credits, 1993 Revision, International Chamber of Commerce Publication No. 500 (the UCP) shall govern commercial Letters of
Credit and the International Standby Practices, 1998, International Chamber of Commerce Publication No. 590 (the ISP) shall govern standby letters of credit. The provisions of the UCP and ISP are hereby incorporated by reference. In
the event of a conflict between the UCP and ISP and the laws of the State, the UCP and ISP shall prevail.

Section 2.4 Interest and
Certain Fee Provisions.

2.4.1 Applicable Margin.

(a) Each Loan shall bear interest at the LIBOR Rate, and the Letter of Credit Fees and the Revolving Credit Unused Line Fees shall be determined, in accordance with the provisions of this Section 2.4.1,
and as may be adjusted from time to time in accordance with the provisions of Section 2.4.2 (Inability to Determine LIBOR Base Rate).

(b) Notwithstanding the foregoing, following the occurrence and during the continuance of an Event of Default, at the option of the Lender, all Loans and all other Obligations until paid shall bear interest at the Post-Default Rate.

(c) The Applicable Margin (i) for LIBOR Loans under the Revolving Credit Facility and for LIBOR Loans evidenced by the Acquisition

(d) Changes in the Applicable Margin for LIBOR Loans, the Letter of Credit Fees and Revolving Credit Unused Line Fee shall be made not more frequently
than quarterly based on the Borrowers Funded Debt to EBITDA ratio determined in accordance with Section 6.1.14(c) and reported on the Compliance Certificate required by Section 6.1.1(c) (Quarterly Statements and Certificates) (except
that the first such determination shall be made based on the Borrowers annual financial statements required by Section 6.1.1(a) (Annual Statements and Certificates) for the Borrowers 2006 Fiscal Year) and shall be effective as of
the first day of the first month after the month in which the Lender receives such statements. The Applicable Margin (expressed as basis points) shall vary depending upon the Borrowers Borrowers Funded Debt to EBITDA ratio, as follows:

2.4.2 Inability to Determine LIBOR Base Rate.

In the event that the Lender shall have determined that, by reason of circumstances affecting the London interbank eurodollar market, adequate and
reasonable means do not exist for ascertaining the LIBOR Base Rate or (b) the Lender shall reasonably determine that the LIBOR Base Rate does not adequately and fairly reflect the cost to the Lender of funding or carrying the Loans, the Lender
shall give telephonic or written notice of such determination to the Borrowers. Thereafter, the interest rate for the Loans shall be based on the Prime Rate and the Applicable Margin shall be established by the Lender at spreads reasonably
determined by the Lender which, when added to the Prime Rate on the Closing Date, would have substantially equaled the spreads over the LIBOR Base Rate provided by the Applicable Margins on the Closing Date.

2.4.3 Indemnity. The Borrowers agree to indemnify and reimburse the Lender and the Lender and to hold the Lender harmless from any loss, cost
(including administrative costs) or expense which the Lender may sustain or incur as a consequence of (a) a default by the Borrowers in payment when due of the principal amount of or interest on any LIBOR Loan, and/or (b) the failure of
the Borrowers to make any prepayment of a LIBOR Loan after the Borrowers have given notice of such intention to make such a prepayment, including, without limitation, any such loss or expense arising from the reemployment of funds obtained by the
Lender to maintain any LIBOR Loan or from fees payable to terminate the deposits from which such funds were obtained. This agreement and covenant of the Borrowers shall survive termination or expiration of this Agreement and payment of the other
Obligations.

2.4.4Payment of Interest.

Unpaid and accrued interest on the Loans shall be paid monthly, in arrears, on the first day of each calendar month, commencing on the first such date after the date of this Agreement, and on the first day of each
calendar month thereafter, and at maturity (whether by acceleration, declaration, extension or otherwise).

2.4.5 Origination Fee.

The Borrowers shall pay to the Lender on or before the Closing Date a loan origination fee (the Origination Fee) in the amount
of Forty-three Thousand Seven Hundred Fifty Dollars ($43,750), which fee has been fully earned and is non-refundable.

2.4.6 Field
Examination Fees.

The Borrowers shall pay to the Lender a field examination fee (collectively, the Field Examination Fees
and individually a Field Examination Fee), which Field Examination Fees shall be payable on the Closing Date and thereafter monthly on the first day of month, and continuing until all Obligations arising out of, or under, the Credit
Facilities then outstanding have been paid in full. Each Field Examination Fee shall be in the amount of $500.

2.4.7 Computation of
Interest and Fees.

All applicable Fees and interest shall be calculated on the basis of a year of 360 days for the actual number of
days elapsed. Any change in the interest rate on any of the Obligations resulting from a change in the Prime Rate shall become effective as of the opening of business on the day on which such change in the Prime Rate is announced.

2.4.8 Maximum Interest Rate.

In no event shall any interest rate provided for hereunder exceed the maximum rate permissible for corporate borrowers under applicable law for loans of
the type provided for hereunder (the Maximum Rate). If, in any month, any interest rate, absent such limitation, would have exceeded the Maximum Rate, then the interest rate for that month shall be the Maximum Rate, and, if in future
months, that interest rate would otherwise be less than the Maximum Rate, then that interest rate shall remain at the Maximum Rate until such time as the amount of interest paid hereunder equals the amount of interest that would have been paid if
the same had not been limited by the Maximum Rate. In the event that, upon payment in full of the Obligations, the total amount of interest paid or accrued under the terms of this Agreement is less than the total amount of interest that would, but
for this Section, have been paid or accrued if the interest rates otherwise set forth in this Agreement had at all times been in effect, then the Borrowers shall, to the extent permitted by applicable law, pay the Lender, an amount equal to the
excess of (a) the lesser of (i) the amount of interest that would have been charged if the Maximum Rate had, at all times, been in effect or (ii) the amount of interest that would have accrued had the interest rates otherwise set
forth in this Agreement, at all times, been in effect over (b) the amount of interest actually paid or accrued under this Agreement. In the event that a court determines that the Lenders have received interest and other charges hereunder in
excess of the Maximum Rate, such excess shall be deemed received on account of, and shall automatically be applied to reduce, the Obligations other than interest, in the inverse order of maturity, and if there are no Obligations outstanding, the
Lenders shall refund to the Borrowers such excess.

2.4.9 Requirements of Law.

In the event that any Lender shall have determined in good faith that (a) the adoption of any Capital Adequacy Regulation, or (b) any change in
any Capital Adequacy Regulation or in the interpretation or application thereof or (c) compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the
force of law) from any central bank or Governmental Authority, does or shall have the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender, as a consequence of the obligations of such Lender
hereunder to a level below that which such Lender or any corporation controlling such Lender would have achieved but for such adoption, change or compliance (taking into consideration the policies of such Lender and the corporation controlling such
Lender, with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrowers of a written request therefor and a statement of the basis for such determination,
the Borrowers shall pay to such Lender such additional amount or amounts in order to compensate for such reduction.

Section 2.5 General
Financing Provisions.

2.5.1 Borrowers Representatives.

(a) The Borrowers hereby represent and warrant to the Lender that each of them will derive benefits, directly and indirectly, from each Letter of Credit
and from each Loan, both in their separate capacity and as a member of the integrated group to which each of the Borrowers belong and because the successful operation of the integrated group is dependent upon the continued successful performance of
the functions of the integrated group as a whole, because (a) this financing is enabling the Purchase Agreement Transaction, (b) the terms of the



38



---

consolidated financing provided under this Agreement are more favorable than would otherwise would be obtainable by the
Borrowers individually, and (c) the Borrowers additional administrative and other costs and reduced flexibility associated with individual financing arrangements which would otherwise be required if obtainable would substantially reduce
the value to the Borrowers of the financing. The Borrowers in the discretion of their respective managements are to agree among themselves as to the allocation of the benefits of Letters of Credit and the proceeds of Loans, provided, however, that
the Borrowers shall be deemed to have represented and warranted to the Lender at the time of allocation that each benefit and use of proceeds is a Permitted Use.

(b) For administrative convenience, each Borrower hereby irrevocably appoints TVI as the Borrowers attorney-in-fact, with power of substitution (with the prior written consent of the Lender in the exercise of
its sole and absolute discretion), in the name of TVI or in the name of the Borrower or otherwise to take any and all actions with respect to the this Agreement, the other Financing Documents, the Obligations and/or the Collateral (including,
without limitation, the proceeds thereof) as TVI may so elect from time to time, including, without limitation, actions to (i) request advances under the Loans, apply for and direct the benefits of Letters of Credits, and direct the Lender to
disburse or credit the proceeds of any Loan directly to an account of TVI, any one or more of the Borrowers or otherwise, which direction shall evidence the making of such Loan and shall constitute the acknowledgement by each of the Borrowers of the
receipt of the proceeds of such Loan or the benefit of such Letter of Credit, (ii) enter into, execute, deliver, amend, modify, restate, substitute, extend and/or renew this Agreement, any other Financing Documents, security agreements,
mortgages, deposit account agreements, instruments, certificates, waivers, letter of credit applications, releases, documents and agreements from time to time, and (iii) endorse any check or other item of payment in the name of the Borrower or
in the name of TVI. The foregoing appointment is coupled with an interest, cannot be revoked without the prior written consent of the Lender, and may be exercised from time to time through TVIs duly authorized officer, officers or other Person
or Persons designated by TVI to act from time to time on behalf of TVI.

(c) Each of the Borrowers hereby irrevocably authorizes the
Lender to make Loans to any one or more of the Borrowers, and hereby irrevocably authorizes the Lender to issue or cause to be issued Letters of Credit for the account of any or all of the Borrowers, pursuant to the provisions of this Agreement upon
the written, oral or telephone request of any one or more of the Persons who is from time to time a Responsible Officer of a Borrower under the provisions of the most recent certificate of corporate resolutions and/or incumbency of the Borrowers on
file with the Lender and also upon the written, oral or telephone request of any one of the Persons who is from time to time a Responsible Officer of the TVI under the provisions of the most recent certificate of corporate resolutions and/or
incumbency for the TVI on file with the Lender.

(d) The Lender assumes no responsibility or liability for any errors, mistakes, and/or
discrepancies in the oral, telephonic, written or other transmissions of any instructions, orders, requests and confirmations between the Lender and the Borrowers in connection with the Credit Facilities, any Loan, and Letter of Credit or any other
transaction in connection with the provisions of this Agreement. Without implying any limitation on the joint and several nature of the Obligations, the Lender agrees that, notwithstanding any other provision of this Agreement, the Borrowers may
create reasonable inter-company indebtedness



39



---

between or among the Borrowers with respect to the allocation of the benefits and proceeds of the advances and Credit
Facilities under this Agreement. The Borrowers agree among themselves, and the Lender consents to that agreement, that each Borrower shall have rights of contribution from all of the other Borrowers to the extent such Borrower incurs Obligations in
excess of the proceeds of the Loans received by, or allocated to purposes for the direct benefit of, such Borrower. All such indebtedness and rights shall be, and are hereby agreed by the Borrowers to be, subordinate in priority and payment to the
indefeasible repayment in full in cash of the Obligations, and, unless the Lender agrees in writing otherwise, shall not be exercised or repaid in whole or in part until all of the Obligations have been indefeasibly paid in full in cash. The
Borrowers agree that all of such inter-company indebtedness and rights of contribution are part of the Collateral and secure the Obligations. Each Borrower hereby waives all rights of counterclaim, recoupment and offset between or among themselves
arising on account of that indebtedness and otherwise. Each Borrower shall not evidence the inter-company indebtedness or rights of contribution by note or other instrument, and shall not secure such indebtedness or rights of contribution with any
Lien or security. Notwithstanding anything contained in this Agreement to the contrary, the amount covered by each Borrower under the Obligations (including, without limitation, Section 2.5.5 (Guaranty)) shall be limited to an aggregate amount
(after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Borrower in respect of the Obligations) which, together with other amounts owing by such Borrowers to the Lender under
the Obligations, is equal to the largest amount that would not be subject to avoidance under the Bankruptcy Code or any applicable provisions of any applicable, comparable state or other Laws.

2.5.2 Use of Proceeds of the Loans.

The proceeds of each advance under the Loans shall be used by the Borrowers for Permitted Uses, and for no other purposes except as may otherwise be agreed by the Lender in writing. The Borrowers shall use the proceeds of the Loans
promptly.

2.5.3 Payments.

All payments of the Obligations, including, without limitation, principal, interest, Prepayments, and Fees, shall be paid by the Borrowers without setoff or counterclaim to the Lender (except as otherwise provided herein) at the
Lenders office specified in Section 8.1 (Notices) in immediately available funds not later than noon (Baltimore Maryland Time) on the due date of such payment. All payments received by the Lender after such time shall be deemed to have
been received by the Lender for purposes of computing interest and Fees and otherwise as of the next Business Day. Payments shall not be considered received by the Lender until such payments are paid to the Lender in immediately available funds. The
Lender shall have no obligation, however, to apply to the Obligations any proceeds from Receivables, any other Collateral, other obligation or property of any kind due from, owed by or belonging to, a Sanctioned Person.

2.5.4 Liens; Setoff.

The Borrowers
hereby grant to the Lender a continuing Lien for all of the Obligations upon any and all monies, securities, and other property of the Borrowers and the proceeds thereof, now or hereafter held or received by or in transit to, the Lender, and/or any
Affiliate of the Lender, from or for the Borrowers, and also upon any and all deposit accounts (general or special) and credits of the Borrowers, if any, with the Lender or any Affiliate of the



40



---

Lender, at any time existing, excluding any deposit accounts held by the Borrowers in their capacity as trustee for
Persons who are not Borrowers or Affiliates of the Borrowers, separate payroll, employee benefit plan deposit accounts, and escrow accounts, but only to the extent the same are clearly titled as such and cannot be subject to a Lien or levy of any
Person. Without implying any limitation on any other rights the Lender may have under the Financing Documents or applicable Laws, during the continuance of an Event of Default, the Lender is hereby authorized by the Borrowers at any time and from
time to time, without notice to the Borrowers, to set off, appropriate and apply any or all items hereinabove referred to (except excluded items) against all Obligations then outstanding (whether or not then due), all in such order and manner as
shall be determined by the Lender in its sole and absolute discretion.

2.5.5 Guaranty.

(a) Each Borrower hereby unconditionally and irrevocably, guarantees to the Lender:

(i) the due and punctual payment in full (and not merely the collectibility) by the other Borrowers of the Obligations, including unpaid
and accrued interest thereon, in each case when due and payable, all according to the terms of this Agreement, the Notes and the other Financing Documents;

(ii) the due and punctual payment in full (and not merely the collectibility) by the other Borrowers of all other sums and charges which

(iii) the due and punctual performance by the other Borrowers of all of the other terms, covenants and conditions contained in the Financing Documents; and

(iv) all the other Obligations of the other Borrowers.

(b) The obligations and liabilities of each Borrower as a guarantor under this Section 2.5.5 shall be absolute and unconditional and joint and several, irrespective of the genuineness, validity, priority,
regularity or enforceability of this Agreement, any of the Notes or any of the Financing Documents or any other circumstance which might otherwise constitute a legal or equitable discharge of a surety or guarantor. Each Borrower in its capacity as a
guarantor expressly agrees that the Lender may, in its sole and absolute discretion, without notice to or further assent of such Borrower and without in any way releasing, affecting or in any way impairing the joint and several obligations and
liabilities of such Borrower as a guarantor hereunder:

(i) waive compliance with, or any defaults under, or grant any
other indulgences under or with respect to any of the Financing Documents;

Documents;

in default;

(vii) make future advances pursuant to the Financing Agreement or any of the other Financing Documents;

(viii) assign, pledge, hypothecate or otherwise transfer the Commitment, the Obligations, the Notes, any of the other
Financing Documents or any interest therein, all as and to the extent permitted by the provisions of this Agreement;

(ix)
deal in all respects with the other Borrowers as if this Section 2.5.5 were not in effect;

(x) effect any release,
compromise or settlement with any of the other Borrowers, whether in their capacity as a Borrower or as a guarantor under this Section 2.5.5, or any other guarantor; and

(xi) provide debtor-in-possession financing or allow use of cash collateral in proceedings under the Bankruptcy Code, it being expressly
agreed by all Borrowers that any such financing and/or use would be part of the Obligations.

(c) The obligations and liabilities of each
Borrower, as guarantor under this Section 2.5.5, shall be primary, direct and immediate, shall not be subject to any counterclaim, recoupment, set off, reduction or defense based upon any claim that a Borrower may have against any one or more
of the other Borrowers, the Lender, and/or any other guarantor and shall not be conditional or contingent upon pursuit or enforcement by the Lender of any remedies it may have against the Borrowers with respect to this Agreement, the Notes or any of
the other Financing Documents, whether pursuant to the terms thereof or by operation of law. Without limiting the generality of the foregoing, the Lender shall not be required to make any



42



---

demand upon any of the Borrowers, or to sell the Collateral or otherwise pursue, enforce or exhaust its remedies against
the Borrowers or the Collateral either before, concurrently with or after pursuing or enforcing its rights and remedies hereunder. Any one or more successive or concurrent actions or proceedings may be brought against each Borrower under this
Section 2.5.5, either in the same action, if any, brought against any one or more of the Borrowers or in separate actions or proceedings, as often as the Lender may deem expedient or advisable. Without limiting the foregoing, it is specifically
understood that any modification, limitation or discharge of any of the liabilities or obligations of any one or more of the Borrowers, any other guarantor or any obligor under any of the Financing Documents, arising out of, or by virtue of, any
bankruptcy, arrangement, reorganization or similar proceeding for relief of debtors under federal or state law initiated by or against any one or more of the Borrowers, in their respective capacities as borrowers and guarantors under this
Section 2.5.5, or under any of the Financing Documents shall not modify, limit, lessen, reduce, impair, discharge, or otherwise affect the liability of each Borrower under this Section 2.5.5 in any manner whatsoever, and this
Section 2.5.5 shall remain and continue in full force and effect. It is the intent and purpose of this Section 2.5.5 that each Borrower shall and does hereby waive all rights and benefits which might accrue to any other guarantor by reason
of any such proceeding, and the Borrowers agree that they shall be liable for the full amount of the obligations and liabilities under this Section 2.5.5, regardless of, and irrespective to, any modification, limitation or discharge of the
liability of any one or more of the Borrowers, any other guarantor or any obligor under any of the Financing Documents, that may result from any such proceedings.

(d) Each Borrower, as guarantor under this Section 2.5.5, hereby unconditionally, jointly and severally, irrevocably and expressly waives:

(i) presentment and demand for payment of the Obligations and protest of non-payment;

(ii) notice of acceptance of this Section 2.5.5 and of presentment, demand and protest thereof;

(iii) notice of any default hereunder or under the Notes or any of the other Financing Documents and notice of all indulgences;

persons as the Lender may direct with a written certificate, duly acknowledged stating in detail whether or not any credits, offsets or defenses exist with respect to this Section 2.5.5.

2.5.6 Bank Products.

The Borrowers
may request, and the Lender or its Affiliates may, in their sole and absolute discretion, provide, Bank Products although the Borrowers are not required to do so. In the event the Borrowers request the Lender and/or its Affiliates to procure or
provide Bank Products, then the Borrowers agree with the Lender and/or such Affiliates, as applicable, to pay when due all indebtedness, liabilities and obligations with respect to Bank Products and further agree to indemnify and hold the Lender
and/or such Affiliates harmless from any and all indebtedness, liabilities, obligations, losses, costs and expenses (including, without limitation, reasonable attorneys fees) now or hereafter owing to or incurred by the Lender (including, without
limitation, those under agreements of indemnifications or assurances provided by the Lender to its affiliates) and/or its Affiliates with respect to Bank Products, all as the same may arise. In the event the Borrowers shall not have paid to the
Lender and/or its Affiliates such amounts, the Lender may cover such amounts by an advance under the Revolving Loan, which advance shall be deemed to have been requested by the Borrowers. The Borrowers acknowledge and agree that (a) all
indebtedness, liabilities and obligations with respect to Bank Products provided by the Lender or its affiliates, and all of its agreements under this Section, are part of the Obligations secured by the Collateral, and (b) the obtaining of Bank
Products from the Lender or its affiliates (i) is in the sole and absolute discretion of the Lender or its affiliates and (ii) is subject to all rules and regulations of the Lender or its affiliates.

Lender any obligation or liability of any of the Borrowers under the Purchase Agreement and/or under any of the other Purchase Agreement Documents. The Borrowers hereby agree to indemnify the Lender and hold the Lender harmless from any and all
claims, actions, suits, losses, damages, costs, expenses, fees, obligations and liabilities that may be incurred by or imposed upon the Lender by virtue of the assignment of and Lien on each of the Borrowers rights, title and interest in, to,

7.2.1Acceleration.

The Lender may
declare any or all of the Obligations to be immediately due and payable, notwithstanding anything contained in this Agreement or in any of the other Financing Documents to the contrary, without presentment, demand, protest, notice of protest or of
dishonor, or other notice of any kind, all of which the Borrowers hereby waive.

7.2.2Further Advances.

The Lender may from time to time without notice to the Borrowers suspend, terminate or limit any further Advances, loans or other extensions of credit
under the Commitment, under this Agreement and/or under any of the other Financing Documents. Further, upon the occurrence of an Event of Default or Default specified in Sections 7.1.5 (Receiver; Bankruptcy) or 7.1.6 (Involuntary Bankruptcy, etc.),
the Revolving Credit Commitment and any agreement in any of the Financing Documents to provide additional credit and/or to issue Letters of Credit shall immediately and automatically terminate and the unpaid principal amount of the Notes (with
accrued interest thereon) and all other Obligations then outstanding, shall immediately become due and payable without further action of any kind and without presentment, demand, protest or notice of any kind, all of which are hereby expressly
waived by the Borrowers.

7.2.3Uniform Commercial Code.

The Lender shall have all of the rights and remedies of a secured party under the applicable Uniform Commercial Code and other applicable Laws. Upon
demand by the Lender, the Borrowers shall assemble the Collateral and make it available to the Lender, at a place designated by the Lender. The Lender or its agents may without notice from time to time enter upon any Borrowers premises to take
possession of the Collateral, to remove it, to render it unusable, to process it or otherwise prepare it for sale, or to sell or otherwise dispose of it.

Any written notice of the sale, disposition or other intended action by the Lender with respect to the Collateral that is sent by regular mail, postage prepaid, to the Borrowers at the address set forth in
Section 8.1 (Notices), or such other address of the Borrowers that may from



78



---

time to time be shown on the Lenders records, at least ten (10) days prior to such sale, disposition or other
action, shall constitute commercially reasonable notice to the Borrowers. The Lender may alternatively or additionally give such notice in any other commercially reasonable manner. Nothing in this Agreement shall require the Lender to give any
notice not required by applicable Laws.

If any consent, approval, or authorization of any state, municipal or other Governmental Authority
or of any other Person or of any Person having any interest therein, should be necessary to effectuate any sale or other disposition of the Collateral, the Borrowers agree to execute all such applications and other instruments, and to take all other
action, as may be required in connection with securing any such consent, approval or authorization.

The Borrowers recognize that the
Lender may be unable to effect a public sale of all or a part of the Collateral consisting of Investment Property by reason of certain prohibitions contained in the Securities Act of 1933, as amended, and other applicable Federal and state Laws. The
Lender may, therefore, in its discretion, take such steps as it may deem appropriate to comply with such Laws and may, for example, at any sale of the Collateral consisting of securities restrict the prospective bidders or purchasers as to their
number, nature of business and investment intention, including, without limitation, a requirement that the Persons making such purchases represent and agree to the satisfaction of the Lender that they are purchasing such securities for their
account, for investment, and not with a view to the distribution or resale of any thereof. The Borrowers covenant and agree to do or cause to be done promptly all such acts and things as the Lender may request from time to time and as may be
necessary to offer and/or sell the securities or any part thereof in a manner that is valid and binding and in conformance with all applicable Laws. Upon any such sale or disposition, the Lender shall have the right to deliver, assign and transfer
to the purchaser thereof the Collateral consisting of securities so sold.

7.2.4Collateral Account; Lockbox.

Without implying any limitation on any of the Lenders other rights and remedies, if directed by the Lender, the Borrowers will deposit, or cause to
be deposited, all Items of Payment to a bank account designated by the Lender and from which the Lender alone has power of access and withdrawal (the Collateral Account). Each deposit shall be made not later than the next Business Day
after the date of receipt of the Items of Payment. The Items of Payment shall be deposited in precisely the form received, except for the endorsements of the Borrowers where necessary to permit the collection of any such Items of Payment, which
endorsement the Borrowers hereby agree to make. In the event the Borrowers fail to do so, the Borrowers hereby authorize the Lender to make the endorsement in the name of any or all of the Borrowers. Prior to such a deposit, the Borrowers will not
commingle any Items of Payment with any of the Borrowers other funds or property, but will hold them separate and apart in trust and for the account of the Lender.

The Borrowers hereby authorize the Lender to inspect all Items of Payment, endorse all Items of Payment in the name of any or all of the Borrowers, and deposit such Items of Payment in the Collateral Account. The
Lender reserves the right, exercised in its sole and absolute discretion from time to time, to provide to the Collateral Account credit prior to final collection of an Item of Payment and to disallow credit for any Item of Payment that is
unsatisfactory to the Lender. In the event Items of Payment are returned to the Lender for any reason whatsoever, the Lender may, in the exercise of its discretion from time to time, forward such Items of Payment a second time. Any returned Items of
Payment shall be charged back to the Collateral Account, the Revolving Loan Account, or other account, as appropriate.



79



---

The Lender will apply the whole or any part of the collected funds credited to the Collateral Account
against any of the Obligations, the order and method of such application to be in the sole discretion of the Lender.

If so directed by the
Lender, the Borrowers shall direct the mailing of all Items of Payment from their Account Debtors to one or more post-office boxes designated by the Lender, or to such other additional or replacement post-office boxes pursuant to the request of the
Lender from time to time (collectively, the Lockbox). The Lender shall have unrestricted and exclusive access to the Lockbox.

7.2.5Specific Rights With Regard to Collateral.

shall exist at law or in equity from time to time, the Lender may (but shall be under no obligation to), without notice to any of the Borrowers, and each Borrower hereby irrevocably appoints the Lender as its attorney-in-fact, with power of
substitution, in the name of the Lender and/or in the name of any or all of the Borrowers or otherwise, for the use and benefit of the Lender, but at the cost and expense of the Borrowers and without notice to the Borrowers:

Agreement.

7.2.6Application of Proceeds.

Any proceeds of sale or other disposition of the Collateral will be applied by the Lender to the payment of any and all Enforcement Costs, and any balance of such proceeds will be applied to the Obligations in such
order and manner as the Lender may from time to time in its sole and absolute discretion determine. If the sale or other disposition of the Collateral fails to fully satisfy the Obligations, the Borrowers shall remain liable to the Lender for any
deficiency.

7.2.7Performance by Lender.

If the Borrowers shall fail to pay the Obligations or otherwise fail to perform, observe or comply with any of the conditions, covenants, terms, stipulations or agreements contained in this Agreement or any of the
other Financing Documents, the Lender without notice to or demand upon the Borrowers and without waiving or releasing any of the Obligations or any Default or Event of Default, may (but shall be under no obligation to) at any time thereafter make
such payment or perform such act for the account and at the expense of the Borrowers, and may enter upon the premises of the Borrowers for that purpose and take all such action thereon as the Lender may consider necessary or appropriate for such
purpose and each of the Borrowers hereby irrevocably appoints the Lender as its attorney-in-fact to do so, with power of substitution, in the name of the Lender, in the name of any or all of the Borrowers or otherwise, for the use and benefit of the
Lender, but at the cost and expense of the Borrowers and without notice to the Borrowers. All sums so paid or advanced by the Lender together with interest thereon from the date of payment, advance or incurring until paid in full at the Post-Default
Rate and all costs and expenses, shall be deemed part of the Enforcement Costs, shall be paid by the Borrowers to the Lender on demand, and shall constitute and become a part of the Obligations.

7.2.8Other Remedies.

The Lender may from time to time proceed to protect or enforce the rights of the Lender by an action or actions at law or in equity or by any other
appropriate proceeding, whether for the specific performance of any of the covenants contained in this Agreement or in any of the other Financing Documents, or for an injunction against the violation of any of the terms of this Agreement or any of
the other Financing Documents, or in aid of the exercise or execution of any right, remedy or power granted in this Agreement, the Financing Documents, and/or applicable Laws. The Lender is authorized to offset and apply to all or any part of the
Obligations all moneys, credits and other property of any nature whatsoever of any or all of the Borrowers now or at any time hereafter in the possession of, in transit to or from, under the control or custody of, or on deposit with, the Lender or

effective unless the same shall be in writing signed by the Lender. No course of dealing between the Borrowers and the Lender and no act or failure to act from time to time on the part of the Lender shall constitute a waiver, amendment or
modification of any provision of this Agreement or any of the other Financing Documents or any right or remedy under this Agreement, under any of the other Financing Documents or under applicable Laws. Without implying any limitation on the
foregoing:

subsequent or other Default or Event of Default, or impair any right consequent thereto.

(c) No notice to or demand on the Borrowers in
any case shall entitle the Borrowers to any other or further notice or demand in the same, similar or other circumstance.

or delay by the Lender to insist upon the strict performance of any term, condition, covenant or agreement of this Agreement or of any of the other Financing Documents, or to exercise any right, power or remedy consequent

agreement or of any such breach or preclude the Lender from exercising any such right, power or remedy at any time or times.

(e) By
accepting payment after the due date of any amount payable under this Agreement or under any of the other Financing Documents, the Lender shall not be deemed to waive the right either to require prompt payment when due of all other amounts payable
under this Agreement or under any of the other Financing Documents, or to declare a default for failure to effect such prompt payment of any such other amount.

Section 8.3 Cumulative Remedies.

The rights, powers and remedies provided in this Agreement and
in the other Financing Documents are cumulative, may be exercised concurrently or separately, may be exercised from time to time and in such order as the Lender shall determine and are in addition to, and not exclusive of, rights, powers and
remedies provided by existing or future applicable Laws, all without regard to any right of the Borrowers or any other Person to the marshalling of assets, which right the Borrowers and any other Person who may be liable (by endorsement, guaranty,
indemnity or otherwise) for all or any part of the Obligations hereby waive to the extent permitted by applicable Laws. In order to entitle the Lender to exercise any remedy reserved to it in this Agreement, it shall not be necessary to give any
notice, other than such notice as may be expressly required in this Agreement. Without limiting the generality of the foregoing and subject to the terms of this Agreement, the Lender may:

(v) accept partial payments or extend from time to time the maturity of all or any part of the Obligations.

Section 8.4 Severability.

In
case one or more provisions, or part thereof, contained in this Agreement or in the other Financing Documents shall be invalid, illegal or unenforceable in any respect under any Law, then without need for any further agreement, notice or action:

(a) the validity, legality and enforceability of the remaining provisions shall remain effective and binding on the parties thereto and
shall not be affected or impaired thereby;

(b) the obligation to be fulfilled shall be reduced to the limit of such validity;

(c) if such provision or part thereof pertains to repayment of the Obligations, then, at the sole and absolute discretion of the Lender, all of the
Obligations of the Borrowers to the Lender shall become immediately due and payable; and

(d) if the affected provision or part thereof
does not pertain to repayment of the Obligations, but operates or would prospectively operate to invalidate this Agreement in whole or in part, then such provision or part thereof only shall be void, and the remainder of this Agreement shall remain
operative and in full force and effect.

Section 8.5 Assignments by Lender.

The Lender may, without notice to, or consent of, the Borrowers, sell, assign or transfer to or participate with any Person or Persons all or any part of
the Obligations, and each such Person or Persons shall have the right to enforce the provisions of this Agreement and any of the other Financing Documents as fully as the Lender, provided that the Lender shall continue to have the unimpaired right
to enforce the provisions of this Agreement and any of the other Financing Documents as to so much of the Obligations that the Lender has not sold, assigned or transferred. In connection with the foregoing, the Lender shall have the right to
disclose to any such actual or potential purchaser, assignee, transferee or participant all financial records, information, reports, financial statements and documents obtained in connection with this Agreement and any of the other Financing
Documents or otherwise, subject, however, to applicable Laws relating to confidentiality of bank information. In addition, notwithstanding the foregoing, the Lender may at any time pledge all or any portion of the Lenders rights under
this Agreement, any Commitment or any of the Obligations to a Federal Reserve Bank.

Section 8.6 Successors and Assigns.

This Agreement and all other Financing Documents shall be binding upon and inure to the benefit of the Borrowers and the Lender and their

Section 8.7 Continuing Agreements.

All covenants, agreements, representations and warranties made by the Borrowers in this Agreement, in any of the other Financing Documents, and in any
certificate delivered pursuant hereto or thereto shall survive the making by the Lender of the Loans, the issuance of Letters of Credit by the Lender and the execution and delivery of the Notes, shall be binding upon the Borrowers regardless of how
long before or after the date hereof any of the Obligations were or are incurred, and shall continue in full force and effect so long as any of the Obligations are outstanding and unpaid. From time to time upon the Lenders request, and as a
condition of the release of any one or more of the Security Documents, the Borrowers and other Persons obligated with respect to the Obligations shall provide the Lender with such acknowledgments and agreements as the Lender may require to the
effect that there exists no defenses, rights of setoff or recoupment, claims, counterclaims, actions or causes of action of any kind or nature whatsoever against the Lender and/or any of its agents and others, or to the extent there are, the same
are waived and released.

Section 8.8 Enforcement Costs.

The Borrowers agree to pay to the Lender on demand all Enforcement Costs, together with interest thereon from the date incurred or advanced until paid in
full at a per annum rate of interest equal at all times to the Post-Default Rate. Enforcement Costs shall be immediately due and payable at the time advanced or incurred, whichever is earlier. Without implying any limitation on the foregoing, the
Borrowers agree, as part of the Enforcement Costs, to pay upon demand any and all stamp and other Taxes and fees payable or determined to be payable in connection with the execution and delivery of this Agreement and the other Financing Documents
and to save the Lender harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay any Taxes or fees referred to in this Section. The provisions of this Section shall survive the
execution and delivery of this Agreement, the repayment of the other Obligations and shall survive the termination of this Agreement.

Section 8.9 Applicable Law; Jurisdiction.

8.9.1 Applicable Law.

The Borrowers acknowledge and agree that the Financing Documents, including, this Agreement, shall be governed by the Laws of the State, as if each of the
Financing Documents and this Agreement had each been executed, delivered, administered and performed solely within the State even though for the convenience and at the request of the Borrowers, one or more of the Financing Documents may be executed
elsewhere. The Lender acknowledges, however, that remedies under certain of the Financing Documents which relate to property outside the State may be subject to the laws of the state in which the property is located.

8.9.2Submission to Jurisdiction.

The Borrowers irrevocably submit to the jurisdiction of any state or federal court sitting in the State over any suit, action or proceeding arising out of or relating to this Agreement or any of the other Financing Documents. Each of the
Borrowers irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit,
action or proceeding brought in any such court has been brought in an inconvenient



86



---

forum. Final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding
upon the Borrowers and may be enforced in any court in which the Borrowers are subject to jurisdiction, by a suit upon such judgment, provided that service of process is effected upon the Borrowers in one of the manners specified in this Section or
as otherwise permitted by applicable Laws.

8.9.3 Appointment of Agent for Service of Process.

The Borrowers hereby irrevocably designate and appoint the resident agent for TVI as disclosed in the records of the Maryland State Department of
Assessments and Taxation, as the Borrowers authorized agent to receive on the Borrowers behalf service of any and all process that may be served in any suit, action or proceeding of the nature referred to in this Section in any state or
federal court sitting in the State. If such agent shall cease so to act, the Borrowers shall irrevocably designate and appoint without delay another such agent in the State satisfactory to the Lender and shall promptly deliver to the Lender evidence
in writing of such other agents acceptance of such appointment and its agreement that such appointment shall be irrevocable.

8.9.4
Service of Process.

Each of the Borrowers hereby consents to process being served in any suit, action or proceeding of the nature
referred to in this Section by (a) the mailing of a copy thereof by registered or certified mail, postage prepaid, return receipt requested, to the Borrower at the Borrowers address designated in or pursuant to Section 8.1 (Notices),
and (b) serving a copy thereof upon the agent, if any, designated and appointed by the Borrower as the Borrowers agent for service of process by or pursuant to this Section. The Borrowers irrevocably agree that such service (y) shall
be deemed in every respect effective service of process upon the Borrowers in any such suit, action or proceeding, and (z) shall, to the fullest extent permitted by law, be taken and held to be valid personal service upon the Borrowers. Nothing
in this Section shall affect the right of the Lender to serve process in any manner otherwise permitted by law or limit the right of the Lender otherwise to bring proceedings against the Borrowers in the courts of any jurisdiction or jurisdictions.

Section 8.10 Duplicate Originals and Counterparts.

This Agreement may be executed in any number of duplicate originals or counterparts, each of such duplicate originals or counterparts shall be deemed to
be an original and all taken together shall constitute but one and the same instrument.

Section 8.11 No Agency.

Nothing herein contained shall be construed to constitute the Borrowers as the agent of the Lender for any purpose whatsoever or to permit the Borrowers
to pledge any of the credit of the Lender. The Lender shall not be responsible or liable for any shortage, discrepancy, damage, loss or destruction of any part of the Collateral wherever the same may be located and regardless of the cause thereof.
The Lender shall not, by anything herein or in any of the Financing Documents or otherwise, assume any of the Borrowers obligations under any contract or agreement assigned to the Lender, and the Lender shall not be responsible in any way for
the performance by the Borrowers of any of the terms and conditions thereof.



87



---

Section 8.12 Date of Payment.

Should the principal of or interest on the Notes become due and payable on other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day and in the case of principal, interest shall be payable thereon at the rate per annum specified in the Notes during such extension.

Section 8.13 Entire Agreement.

This Agreement is intended by the Lender and the Borrowers to be
a complete, exclusive and final expression of the agreements contained herein. Neither the Lender nor the Borrowers shall hereafter have any rights under any prior agreements pertaining to the matters addressed by this Agreement but shall look
solely to this Agreement for definition and determination of all of their respective rights, liabilities and responsibilities under this Agreement.

Section 8.14 Waiver of Trial by Jury.

THE BORROWERS AND THE LENDERS HEREBY JOINTLY AND SEVERALLY WAIVE TRIAL BY JURY
IN ANY ACTION OR PROCEEDING TO WHICH THE BORROWER AND THE LENDER MAY BE PARTIES, ARISING OUT OF OR IN ANY WAY PERTAINING TO (A) THIS AGREEMENT, (B) ANY OF THE FINANCING DOCUMENTS, OR (C) THE COLLATERAL. THIS WAIVER CONSTITUTES A
WAIVER OF TRIAL BY JURY OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH ACTIONS OR PROCEEDINGS, INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO THIS AGREEMENT.

This waiver is knowingly, willingly and voluntarily made by the Borrowers and the Lender, and the Borrowers and the Lender hereby represent that no representations of fact or opinion have been made by any individual
to induce this waiver of trial by jury or to in any way modify or nullify its effect. The Borrowers and the Lender further represent that they have been represented in the signing of this Agreement and in the making of this waiver by independent
legal counsel, selected of their own free will, and that they have had the opportunity to discuss this waiver with counsel.

Section 8.15 Liability of the Lender.

The Borrowers hereby agree that the Lender shall not be chargeable for any
negligence, mistake, act or omission of any accountant, examiner, agency or attorney employed by the Lender in making examinations, investigations or collections, or otherwise in perfecting, maintaining, protecting or realizing upon any lien or
security interest or any other interest in the Collateral or other security for the Obligations.

By inspecting the Collateral or any other
properties of the Borrowers or by accepting or approving anything required to be observed, performed or fulfilled by the Borrowers or to be given to the Lender pursuant to this Agreement or any of the other Financing Documents, the Lender shall not
be deemed to have warranted or represented the condition, sufficiency, legality, effectiveness or legal effect of the same, and such acceptance or approval shall not constitute any warranty or representation with respect thereto by the Lender.

Section 8.16 Indemnification.

The Borrowers agrees to indemnify and hold harmless, Lender, the respective parent and Affiliates of the Lender and the respective parents and
Affiliates officers, directors, shareholders, employees and agents (each an Indemnified Party, and collectively, the Indemnified Parties), from and against any and all claims, liabilities, losses, damages, costs and
expenses (whether or not such Indemnified Party is a party to any litigation), including without limitation, reasonable attorneys fees and costs and costs of investigation, document production, attendance at depositions or other discovery,
incurred by any Indemnified Party with respect to, arising out of or as a consequence of (a) this Agreement or any of the other Financing Documents, including without limitation, any failure of the Borrowers to pay when due (at maturity, by
acceleration or otherwise) any principal, interest, fee or any other amount due under this Agreement or the other Loan documents, or any other Event of Default; (b) the use by the Borrowers of any proceeds advanced hereunder; (c) the
transactions contemplated hereunder; or (d) any civil penalty or fine assessed by OFAC against the Lender or any Affiliate of the Lender and all reasonable costs and expense (including counsel fees and disbursements) incurred in connection with
defense thereof by the Lender or such Affiliate, as a result of the funding of Loans or the extension of credit, the acceptance of payments due under the Financing Documents or any Hedge Agreement or acceptance of Collateral; (e) any claim,
demand, action or cause of action being asserted against (i) the Borrowers or any of their Affiliates by any other Person, or (ii) any Indemnified Party by the Borrowers in connection with the transactions contemplated hereunder.
Notwithstanding anything herein or elsewhere to the contrary, the Borrowers shall not be obligated to indemnify or hold harmless any Indemnified Party from any liability, loss or damage resulting from the gross negligence or willful misconduct (as
determined by a final non-appealable order by a court of competent jurisdiction) of such Indemnified Party. Any amount payable to the Lender under this Section will bear interest at the Post- Default Rate from the due date until paid.

REVOLVING CREDIT NOTE

$25,000,000                                     
                                        
                                        
                                        
      Baltimore, Maryland

October 31, 2006

FOR VALUE RECEIVED, TVI CORPORATION, a Maryland corporation (TVI), CAPA MANUFACTURING CORP., a Maryland corporation (CAPA), SAFETY TECH INTERNATIONAL, INC., a Maryland corporation (Safety
Tech) and TVI HOLDINGS ONE, INC., a Maryland corporation (Signature TVI), jointly and severally (each of TVI, CAPA, Safety Tech and Signature TVI, a Borrower; TVI, CAPA, Safety Tech and Signature TVI, collectively,
the Borrowers), promise to pay to the order of BRANCH BANKING AND TRUST COMPANY, a North Carolina banking corporation (the Lender), the principal sum of TWENTY-FIVE MILLION DOLLARS ($25,000,000) (the Principal
Sum), or so much thereof as has been or may be advanced/readvanced to or for the account of the Borrowers pursuant to the terms and conditions of the Financing Agreement (as hereinafter defined) under the Revolving Credit Facility (as that
term is defined in the Financing Agreement), together with interest thereon at the rate or rates hereinafter provided, in accordance with the following:



| | 1. | Interest.
| | -- | ---------

Commencing as of the date hereof and
continuing until repayment in full of all sums due hereunder, the unpaid Principal Sum shall bear interest in accordance with Section 2.4 (Interest and Certain Fee Provisions) of the Financing Agreement.



| | 2. | Payments and Maturity.
| | -- | ----------------------

The unpaid Principal Sum,
together with interest thereon at the rate or rates provided above, shall be payable as follows:

(a) Interest only on the unpaid Principal Sum shall be due and payable in accordance with Section 2.4.4 (Payment of Interest) of the Financing Agreement; and

(b) Unless sooner paid, the unpaid Principal Sum, together with interest accrued and unpaid thereon,
shall be due and payable in full on the Revolving Credit Termination Date (as defined in the Financing Agreement).

The fact that the
balance hereunder may be reduced to zero from time to time pursuant to the Financing Agreement will not affect the continuing validity of this Note or the Financing Agreement, and the balance may be increased to the Principal Sum after any such
reduction to zero.



| | 3. | Default Interest.
| | -- | -----------------

Upon the occurrence of an Event
of Default (as hereinafter defined), the unpaid Principal Sum shall bear interest thereafter at the Post-Default Rate (as defined in the Financing Agreement) until such Event of Default is cured.





---

| | 4. | Late Charges.
| | -- | -------------

If the Borrowers shall fail to make
any payment under the terms of this Note within ten (10) days after the date such payment is due, the Borrowers shall pay to the Lender on demand a late charge equal to five percent (5%) of such payment.



| | 5. | Application and Place of Payments.
| | -- | ----------------------------------

All payments,
made on account of this Note shall be applied first to the payment of any late charge then due hereunder, second to the payment of any prepayment fee then due hereunder, third to the payment of accrued and unpaid interest then due hereunder, and the
remainder, if any, shall be applied to the unpaid Principal Sum. All payments on account of this Note shall be paid in lawful money of the United States of America in immediately available funds during regular business hours of the Lender at its
principal office in Baltimore, Maryland or at such other times and places as the Lender may at any time and from time to time designate in writing to the Borrowers.



| | 6. | Prepayment.
| | -- | -----------

The Borrowers may prepay the Principal
Sum in whole or in part at any time without premium or penalty, provided, however, that the Borrowers are subject to indemnification provisions applicable to prepayment pursuant to the terms of Section 2.4.3 (Indemnity) of the Financing
Agreement.



| | 7. | Financing Agreement and Other Financing Documents.
| | -- | --------------------------------------------------

This Note is the Revolving Credit Note described in a Financing and Security Agreement of even date herewith by and among the Borrowers and the Lender (as amended, modified, restated, substituted, extended and renewed at any
time and from time to time, the Financing Agreement). The indebtedness evidenced by this Note is included within the meaning of the term Obligations as defined in the Financing Agreement. This Note is one of the
Financing Documents (as that term is defined in the Financing Agreement).



| | 8. | Security.
| | -- | ---------

This Note is secured as provided in the
Financing Agreement.



| | 9. | Events of Default.
| | -- | ------------------

The occurrence of any one or
more of the following events shall constitute an event of default (individually, an Event of Default and collectively, the Events of Default) under the terms of this Note:

(a) The failure of the Borrowers to pay to the Lender when due any and all amounts payable by the
Borrowers to the Lender under the terms of this Note; or

(b) The occurrence of an event of
default (as defined therein) under the terms and conditions of any of the other Financing Documents.



2



---

| | 10. | Remedies.
| | --- | ---------

Upon the occurrence of an Event of
Default, at the option of the Lender, all amounts payable by the Borrowers to the Lender under the terms of this Note shall immediately become due and payable by the Borrowers to the Lender without notice to the Borrowers or any other person, and
the Lender shall have all of the rights, powers, and remedies available under the terms of this Note, any of the other Financing Documents and all applicable laws. The Borrowers and all endorsers, guarantors, and other parties who may now or in the
future be primarily or secondarily liable for the payment of the indebtedness evidenced by this Note hereby severally waive presentment, protest and demand, notice of protest, notice of demand and of dishonor and non-payment of this Note and
expressly agree that this Note or any payment hereunder may be extended from time to time without in any way affecting the liability of the Borrowers, guarantors and endorsers.



| | 11. | Expenses.
| | --- | ---------

The Borrowers promise to pay to the
Lender on demand by the Lender all costs and expenses incurred by the Lender in connection with the collection and enforcement of this Note, including, without limitation, reasonable attorneys fees and expenses and all court costs.



| | 12. | Notices.
| | --- | --------

Any notice, request, or demand to or upon
the Borrowers or the Lender shall be deemed to have been properly given or made when delivered in accordance with Section 8.1 (Notices) of the Financing Agreement.



| | 13. | Miscellaneous.
| | --- | --------------

Each right, power, and remedy of
the Lender as provided for in this Note or any of the other Financing Documents, or now or hereafter existing under any applicable law or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy
provided for in this Note or any of the other Financing Documents or now or hereafter existing under any applicable law, and the exercise or beginning of the exercise by the Lender of any one or more of such rights, powers, or remedies shall not
preclude the simultaneous or later exercise by the Lender of any or all such other rights, powers, or remedies. No failure or delay by the Lender to insist upon the strict performance of any term, condition, covenant, or agreement of this Note or
any of the other Financing Documents, or to exercise any right, power, or remedy consequent upon a breach thereof, shall constitute a waiver of any such term, condition, covenant, or agreement or of any such breach, or preclude the Lender from
exercising any such right, power, or remedy at a later time or times. By accepting payment after the due date of any amount payable under the terms of this Note, the Lender shall not be deemed to waive the right either to require prompt payment when
due of all other amounts payable under the terms of this Note or to declare an Event of Default for the failure to effect such prompt payment of any such other amount. No course of dealing or conduct shall be effective to amend, modify, waive,
release, or change any provisions of this Note.



3



---

| | 14. | Partial Invalidity.
| | --- | -------------------

In the event any provision of
this Note (or any part of any provision) is held by a court of competent jurisdiction to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision (or remaining part
of the affected provision) of this Note; but this Note shall be construed as if such invalid, illegal, or unenforceable provision (or part thereof) had not been contained in this Note, but only to the extent it is invalid, illegal, or unenforceable.



| | 15. | Captions.
| | --- | ---------

The captions herein set forth are for
convenience only and shall not be deemed to define, limit, or describe the scope or intent of this Note.



| | 16. | Applicable Law.
| | --- | ---------------

The Borrowers acknowledge and
agree that this Note shall be governed by the laws of the State of Maryland, even though for the convenience and at the request of the Borrowers, this Note may be executed elsewhere.



| | 17. | Consent to Jurisdiction.
| | --- | ------------------------

Each Borrower irrevocably
submits to the jurisdiction of any state or federal court sitting in the State of Maryland over any suit, action, or proceeding arising out of or relating to this Note or any of the other Financing Documents. Each Borrower irrevocably waives, to the
fullest extent permitted by law, any objection that such Borrower may now or hereafter have to the laying of venue of any such suit, action, or proceeding brought in any such court and any claim that any such suit, action, or proceeding brought in
any such court has been brought in an inconvenient forum. Final judgment in any such suit, action, or proceeding brought in any such court shall be conclusive and binding upon each Borrower and may be enforced in any court in which any Borrower is
subject to jurisdiction by a suit upon such judgment, provided that service of process is effected upon the Borrower as provided in this Note or as otherwise permitted by applicable law.



| | 18. | Service of Process.
| | --- | -------------------

Each Borrower hereby consents
to process being served in any suit, action, or proceeding instituted in connection with this Note by (a) the mailing of a copy thereof by certified mail, postage prepaid, return receipt requested, to the Borrowers and (b) serving a copy
thereof upon the registered agent for TVI as set forth in the records of the Maryland State Department of Assessments and Taxation, the agent hereby designated and appointed by each of the Borrowers as each Borrowers agent for service of
process. Each Borrower irrevocably agrees that such service shall be deemed in every respect effective service of process upon the Borrower in any such suit, action or proceeding, and shall, to the fullest extent permitted by law, be taken and held
to be valid personal service upon the Borrower. Nothing in this Section shall affect the right of the Lender to serve process in any manner otherwise permitted by law or limit the right of the Lender otherwise to bring proceedings against any
Borrower in the courts of any jurisdiction or jurisdictions.

EVENT OF DEFAULT, EACH BORROWER HEREBY AUTHORIZES ANY ATTORNEY DESIGNATED BY THE LENDER OR ANY CLERK OF ANY COURT OF RECORD TO APPEAR FOR SUCH BORROWER IN ANY COURT OF RECORD AND CONFESS JUDGMENT WITHOUT PRIOR HEARING AGAINST THE BORROWER IN FAVOR
OF THE LENDER FOR AND IN THE AMOUNT OF THE UNPAID PRINCIPAL SUM, ALL INTEREST ACCRUED AND UNPAID THEREON, ALL OTHER AMOUNTS PAYABLE BY THE BORROWER TO THE LENDER UNDER THE TERMS OF THIS NOTE OR ANY OF THE OTHER FINANCING DOCUMENTS, COSTS OF SUIT,

COLLECTION OF SUMS OWED TO THE LENDER. IN THE EVENT THE LENDER RECEIVES, THROUGH EXECUTION UPON A CONFESSED JUDGMENT, PAYMENTS ON ACCOUNT OF ATTORNEYS FEES IN EXCESS OF SUCH ACTUAL ATTORNEYS FEES AND EXPENSES INCURRED BY THE LENDER,
THEN, AFTER FULL REPAYMENT AND SATISFACTION OF ALL OF THE OBLIGATIONS UNDER AND IN CONNECTION WITH THIS NOTE, THE LOAN AGREEMENT AND ALL OF THE OTHER LOAN DOCUMENTS, THE LENDER SHALL REFUND SUCH EXCESS AMOUNT TO THE BORROWERS. EACH BORROWER HEREBY
RELEASES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ALL ERRORS AND ALL RIGHTS OF EXEMPTION, APPEAL, STAY OF EXECUTION, INQUISITION, AND OTHER RIGHTS TO WHICH SUCH BORROWER MAY OTHERWISE BE ENTITLED UNDER THE LAWS OF THE UNITED STATES OF AMERICA OR
OF ANY STATE OR POSSESSION OF THE UNITED STATES OF AMERICA NOW IN FORCE AND WHICH MAY HEREAFTER BE ENACTED. THE AUTHORITY AND POWER TO APPEAR FOR AND ENTER JUDGMENT AGAINST ANY BORROWER SHALL NOT BE EXHAUSTED BY ONE OR MORE EXERCISES THEREOF OR BY
ANY IMPERFECT EXERCISE THEREOF AND SHALL NOT BE EXTINGUISHED BY ANY JUDGMENT ENTERED PURSUANT THERETO. SUCH AUTHORITY MAY BE EXERCISED ON ONE OR MORE OCCASIONS OR FROM TIME TO TIME IN THE SAME OR DIFFERENT JURISDICTIONS AS OFTEN AS THE LENDER SHALL
DEEM NECESSARY OR DESIRABLE, FOR ALL OF WHICH THIS NOTE SHALL BE A SUFFICIENT WARRANT.

|$10,000,000                                     
                                        
                                        
                                        
     Baltimore, | Maryland
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------

October 31, 2006

FOR VALUE RECEIVED, TVI CORPORATION, a Maryland corporation (TVI), CAPA MANUFACTURING CORP., a Maryland corporation (CAPA),
SAFETY TECH INTERNATIONAL, INC., a Maryland corporation (Safety Tech) and TVI HOLDINGS ONE, INC., a Maryland corporation (Signature TVI), jointly and severally (each of TVI, CAPA, Safety Tech and Signature TVI, a
Borrower; TVI, CAPA, Safety Tech and Signature TVI, collectively, the Borrowers), promise to pay to the order of BRANCH BANKING AND TRUST COMPANY, a North Carolina banking corporation (the Lender), the principal
sum of TEN MILLION DOLLARS ($10,000,000) (the Principal Sum), or so much thereof as has been or may be advanced/readvanced to or for the account of the Borrowers pursuant to the terms and conditions of the Financing Agreement (as
hereinafter defined) as Acquisition Line Advances (as defined in the Financing Agreement) that are not Acquisition Line Term Advances (as defined in the Financing Agreement) under the Acquisition Line Facility (as that term is defined in the
Financing Agreement), together with interest thereon at the rate or rates hereinafter provided, in accordance with the following:



| | 1. | Interest.
| | -- | ---------

Commencing as of the date hereof and
continuing until repayment in full of all sums due hereunder, the unpaid Principal Sum shall bear interest in accordance with Section 2.4 (Interest and Certain Fee Provisions) of the Financing Agreement.



| | 2. | Payments and Maturity.
| | -- | ----------------------

The unpaid Principal Sum,
together with interest thereon at the rate or rates provided above, shall be payable as follows:

(b) Unless sooner paid,
the unpaid Principal Sum, together with interest accrued and unpaid thereon, shall be due and payable in full on the Revolving Credit Termination Date.

The fact that the balance hereunder may be reduced to zero from time to time pursuant to the Financing Agreement will not affect the continuing validity of this Note or the Financing Agreement, and the balance may be
increased to the Principal Sum after any such reduction to zero.



| | 3. | Default Interest.
| | -- | -----------------

Upon the occurrence of an Event
of Default (as hereinafter defined), the unpaid Principal Sum shall bear interest thereafter at the Post-Default Rate (as defined in the Financing Agreement) until such Event of Default is cured.



---

| | 4. | Late Charges.
| | -- | -------------

If the Borrowers shall fail to make
any payment under the terms of this Note within ten (10) days after the date such payment is due, the Borrowers shall pay to the Lender on demand a late charge equal to five percent (5%) of such payment.

All payments,
made on account of this Note shall be applied in accordance with Section 2.2 (Acquisition Line Facility) of the Financing Agreement)

Sum in whole or in part at any time without premium or penalty, provided, however, that the Borrowers are subject to indemnification provisions applicable to prepayment pursuant to the terms of Section 2.4.3 (Indemnity) of the Financing
Agreement.



| | 7. | Financing Agreement and Other Financing Documents.
| | -- | --------------------------------------------------

This Note is the Acquisition Line Revolving Note described in a Financing and Security Agreement of even date herewith by and among the Borrowers and the Lender (as amended, modified, restated, substituted, extended and renewed
at any time and from time to time, the Financing Agreement). The indebtedness evidenced by this Note is included within the meaning of the term Obligations as defined in the Financing Agreement. This Note is one of the
Financing Documents (as that term is defined in the Financing Agreement).



| | 8. | Security.
| | -- | ---------

This Note is secured as provided in the
Financing Agreement.



| | 9. | Events of Default.
| | -- | ------------------

The occurrence of any one or
more of the following events shall constitute an event of default (individually, an Event of Default and collectively, the Events of Default) under the terms of this Note:

(a) The failure of the Borrowers to pay to the Lender when due any and all amounts payable by the Borrowers to the Lender under the terms of this Note;
or

(b) The occurrence of an event of default (as defined therein) under the terms and conditions of any of the other Financing Documents.



| | 10. | Remedies.

person, and the Lender shall have all of the rights, powers, and remedies available under the terms of this Note, any of the other Financing Documents and
all applicable laws. The Borrowers and all endorsers, guarantors, and other parties who may now or in the future be primarily or secondarily liable for the payment of the indebtedness evidenced by this Note hereby severally waive presentment,
protest and demand, notice of protest, notice of demand and of dishonor and non-payment of this Note and expressly agree that this Note or any payment hereunder may be extended from time to time without in any way affecting the liability of the
Borrowers, guarantors and endorsers.



| | 11. | Expenses.
| | --- | ---------

The Borrowers promise to pay to the
Lender on demand by the Lender all costs and expenses incurred by the Lender in connection with the collection and enforcement of this Note, including, without limitation, reasonable attorneys fees and expenses and all court costs.



| | 12. | Notices.
| | --- | --------

Any notice, request, or demand to or upon
the Borrowers or the Lender shall be deemed to have been properly given or made when delivered in accordance with Section 8.1 (Notices) of the Financing Agreement.



| | 13. | Miscellaneous.
| | --- | --------------

Each right, power, and remedy of
the Lender as provided for in this Note or any of the other Financing Documents, or now or hereafter existing under any applicable law or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy
provided for in this Note or any of the other Financing Documents or now or hereafter existing under any applicable law, and the exercise or beginning of the exercise by the Lender of any one or more of such rights, powers, or remedies shall not
preclude the simultaneous or later exercise by the Lender of any or all such other rights, powers, or remedies. No failure or delay by the Lender to insist upon the strict performance of any term, condition, covenant, or agreement of this Note or
any of the other Financing Documents, or to exercise any right, power, or remedy consequent upon a breach thereof, shall constitute a waiver of any such term, condition, covenant, or agreement or of any such breach, or preclude the Lender from
exercising any such right, power, or remedy at a later time or times. By accepting payment after the due date of any amount payable under the terms of this Note, the Lender shall not be deemed to waive the right either to require prompt payment when
due of all other amounts payable under the terms of this Note or to declare an Event of Default for the failure to effect such prompt payment of any such other amount. No course of dealing or conduct shall be effective to amend, modify, waive,
release, or change any provisions of this Note.



| | 14. | Partial Invalidity.
| | --- | -------------------

In the event any provision of
this Note (or any part of any provision) is held by a court of competent jurisdiction to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision (or remaining part
of the affected provision) of this Note; but this Note shall be construed as if such invalid, illegal, or



3



---

unenforceable provision (or part thereof) had not been contained in this Note, but only to the extent it is invalid, illegal, or unenforceable.



| | 15. | Captions.
| | --- | ---------

The captions herein set forth are for
convenience only and shall not be deemed to define, limit, or describe the scope or intent of this Note.



| | 16. | Applicable Law.
| | --- | ---------------

The Borrowers acknowledge and
agree that this Note shall be governed by the laws of the State of Maryland, even though for the convenience and at the request of the Borrowers, this Note may be executed elsewhere.



| | 17. | Consent to Jurisdiction.
| | --- | ------------------------

Each Borrower irrevocably
submits to the jurisdiction of any state or federal court sitting in the State of Maryland over any suit, action, or proceeding arising out of or relating to this Note or any of the other Financing Documents. Each Borrower irrevocably waives, to the
fullest extent permitted by law, any objection that such Borrower may now or hereafter have to the laying of venue of any such suit, action, or proceeding brought in any such court and any claim that any such suit, action, or proceeding brought in
any such court has been brought in an inconvenient forum. Final judgment in any such suit, action, or proceeding brought in any such court shall be conclusive and binding upon each Borrower and may be enforced in any court in which any Borrower is
subject to jurisdiction by a suit upon such judgment, provided that service of process is effected upon the Borrower as provided in this Note or as otherwise permitted by applicable law.



| | 18. | Service of Process.

to be valid personal service upon the Borrower. Nothing in this Section shall affect the right of the Lender to serve process in any manner otherwise permitted by law or limit the right of the Lender otherwise to bring proceedings against any
Borrower in the courts of any jurisdiction or jurisdictions.



| | 19. | Confessed Judgment.

JUDGMENT ENTERED PURSUANT THERETO. SUCH AUTHORITY MAY BE EXERCISED ON ONE OR MORE OCCASIONS OR FROM TIME TO TIME IN THE SAME OR DIFFERENT JURISDICTIONS AS OFTEN AS THE LENDER SHALL DEEM NECESSARY OR DESIRABLE, FOR ALL OF WHICH THIS NOTE SHALL BE A

person, and the Lender shall have all of the rights, powers, and remedies available under the terms of this Note, any of the other Financing Documents and
all applicable laws. The Borrowers and all endorsers, guarantors, and other parties who may now or in the future be primarily or secondarily liable for the payment of the indebtedness evidenced by this Note hereby severally waive presentment,
protest and demand, notice of protest, notice of demand and of dishonor and non-payment of this Note and expressly agree that this Note or any payment hereunder may be extended from time to time without in any way affecting the liability of the

provided for in this Note or any of the other Financing Documents or now or hereafter existing under any applicable law, and the exercise or beginning of the exercise by the Lender of any one or more of such rights, powers, or remedies shall not
preclude the simultaneous or later exercise by the Lender of any or all such other rights, powers, or remedies. No failure or delay by the Lender to insist upon the strict performance of any term, condition, covenant, or agreement of this Note or

exercising any such right, power, or remedy at a later time or times. By accepting payment after the due date of any amount payable under the terms of this Note, the Lender shall not be deemed to waive the right either to require prompt payment when
due of all other amounts payable under the terms of this Note or to declare an Event of Default for the failure to effect such prompt payment of any such other amount. No course of dealing or conduct shall be effective to amend, modify, waive,
release, or change any provisions of this Note.

of the affected provision) of this Note; but this Note shall be construed as if such invalid, illegal, or



3



---

unenforceable provision (or part thereof) had not been contained in this Note, but only to the extent it is invalid, illegal, or unenforceable.

| | --- | ---------

The captions herein set forth are for
convenience only and shall not be deemed to define, limit, or describe the scope or intent of this Note.



| | 16. | Applicable Law.

agree that this Note shall be governed by the laws of the State of Maryland, even though for the convenience and at the request of the Borrowers, this Note may be executed elsewhere.



| | 17. | Consent to Jurisdiction.
| | --- | ------------------------

Each Borrower irrevocably
submits to the jurisdiction of any state or federal court sitting in the State of Maryland over any suit, action, or proceeding arising out of or relating to this Note or any of the other Financing Documents. Each Borrower irrevocably waives, to the
fullest extent permitted by law, any objection that such Borrower may now or hereafter have to the laying of venue of any such suit, action, or proceeding brought in any such court and any claim that any such suit, action, or proceeding brought in
any such court has been brought in an inconvenient forum. Final judgment in any such suit, action, or proceeding brought in any such court shall be conclusive and binding upon each Borrower and may be enforced in any court in which any Borrower is
subject to jurisdiction by a suit upon such judgment, provided that service of process is effected upon the Borrower as provided in this Note or as otherwise permitted by applicable law.

thereof upon the registered agent for TVI as set forth in the records of the Maryland State Department of Assessments and Taxation, the agent hereby designated and appointed by each of the Borrowers as each Borrowers agent for service of
process. Each Borrower irrevocably agrees that such service shall be deemed in every respect effective service of process upon the Borrower in any such suit, action or proceeding, and shall, to the fullest extent permitted by law, be taken and held
to be valid personal service upon the Borrower. Nothing in this Section shall affect the right of the Lender to serve process in any manner otherwise permitted by law or limit the right of the Lender otherwise to bring proceedings against any
Borrower in the courts of any jurisdiction or jurisdictions.



| | 19. | Confessed Judgment.
| | --- | -------------------

UPON THE OCCURRENCE OF AN
EVENT OF DEFAULT, EACH BORROWER HEREBY AUTHORIZES ANY ATTORNEY DESIGNATED BY THE LENDER OR ANY CLERK OF ANY COURT OF RECORD TO APPEAR FOR SUCH BORROWER IN ANY



4



---

COURT OF RECORD AND CONFESS JUDGMENT WITHOUT PRIOR HEARING AGAINST THE BORROWER IN FAVOR OF THE LENDER FOR AND IN THE AMOUNT OF THE UNPAID PRINCIPAL SUM, ALL
INTEREST ACCRUED AND UNPAID THEREON, ALL OTHER AMOUNTS PAYABLE BY THE BORROWER TO THE LENDER UNDER THE TERMS OF THIS NOTE OR ANY OF THE OTHER FINANCING DOCUMENTS, COSTS OF SUIT, AND ATTORNEYS FEES OF FIFTEEN PERCENT (15%) OF THE UNPAID
PRINCIPAL SUM AND INTEREST THEN DUE HEREUNDER. BY ITS ACCEPTANCE OF THIS NOTE, THE LENDER AGREES THAT IN THE EVENT THE LENDER EXERCISES AT ANY TIME ITS RIGHT TO CONFESS JUDGMENT UNDER THIS NOTE, THE LENDER SHALL USE ITS BEST EFFORTS TO OBTAIN LEGAL
COUNSEL WHO WILL CHARGE THE LENDER FOR ITS SERVICES ON AN HOURLY BASIS, AT ITS CUSTOMARY HOURLY RATES AND ONLY FOR THE TIME AND REASONABLE EXPENSES INCURRED. IN NO EVENT SHALL THE LENDER ENFORCE THE LEGAL FEES PORTION OF A CONFESSED JUDGMENT AWARD
FOR AN AMOUNT IN EXCESS OF THE FEES AND EXPENSES ACTUALLY CHARGED TO THE LENDER FOR SERVICES RENDERED BY ITS COUNSEL IN CONNECTION WITH SUCH CONFESSION OF JUDGMENT AND/OR THE COLLECTION OF SUMS OWED TO THE LENDER. IN THE EVENT THE LENDER RECEIVES,
THROUGH EXECUTION UPON A CONFESSED JUDGMENT, PAYMENTS ON ACCOUNT OF ATTORNEYS FEES IN EXCESS OF SUCH ACTUAL ATTORNEYS FEES AND EXPENSES INCURRED BY THE LENDER, THEN, AFTER FULL REPAYMENT AND SATISFACTION OF ALL OF THE OBLIGATIONS UNDER
AND IN CONNECTION WITH THIS NOTE, THE LOAN AGREEMENT AND ALL OF THE OTHER LOAN DOCUMENTS, THE LENDER SHALL REFUND SUCH EXCESS AMOUNT TO THE BORROWERS. EACH BORROWER HEREBY RELEASES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ALL ERRORS AND ALL
RIGHTS OF EXEMPTION, APPEAL, STAY OF EXECUTION, INQUISITION, AND OTHER RIGHTS TO WHICH SUCH BORROWER MAY OTHERWISE BE ENTITLED UNDER THE LAWS OF THE UNITED STATES OF AMERICA OR OF ANY STATE OR POSSESSION OF THE UNITED STATES OF AMERICA NOW IN FORCE
AND WHICH MAY HEREAFTER BE ENACTED. THE AUTHORITY AND POWER TO APPEAR FOR AND ENTER JUDGMENT AGAINST ANY BORROWER SHALL NOT BE EXHAUSTED BY ONE OR MORE EXERCISES THEREOF OR BY ANY IMPERFECT EXERCISE THEREOF AND SHALL NOT BE EXTINGUISHED BY ANY
JUDGMENT ENTERED PURSUANT THERETO. SUCH AUTHORITY MAY BE EXERCISED ON ONE OR MORE OCCASIONS OR FROM TIME TO TIME IN THE SAME OR DIFFERENT JURISDICTIONS AS OFTEN AS THE LENDER SHALL DEEM NECESSARY OR DESIRABLE, FOR ALL OF WHICH THIS NOTE SHALL BE A
SUFFICIENT WARRANT.



| | 20. | WAIVER OF TRIAL BY JURY.

EACH BORROWER
AND THE LENDER (BY ITS ACCEPTANCE HEREOF) HEREBY WAIVE TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO WHICH SUCH BORROWER AND THE LENDER MAY BE PARTIES, ARISING OUT OF OR IN ANY WAY PERTAINING TO (A) THIS NOTE OR (B) THE FINANCING DOCUMENTS.
