Bank may price loans to its customers at, above, or below the Bank’s Prime Rate. Any change in the Bank’s Prime Rate shall take effect at the opening of business on the day specified in the public announcement of a change in the
Bank’s Prime Rate. 
  

 9 

	 	2.5	Optional Interest Rates.

Letters of Credit outstanding, including amounts drawn on any Letters of Credit and not yet reimbursed. 
 (e) The Borrower
agrees: 
 (i) Any sum drawn under a Letter of Credit may, at the option of the Bank, be added to the principal amount
outstanding under this Agreement. The amount will bear interest and be due as described elsewhere in this Agreement. 
 (ii)
If there is a default under this Agreement to immediately prepay and make the Bank whole for any outstanding Letters of Credit, or at the Bank’s option and in such case upon written request by the Bank, provide cash collateral equal to the face

 (iii) The issuance of any Letter of Credit and any amendment to a Letter of
Credit is subject to the Bank’s written approval and must be in form and content satisfactory to the Bank.

outstanding undrawn amount of each Standby Letter of Credit, payable quarterly in arrears and upon expiration or termination of the applicable Standby Letter of Credit, calculated on the basis of the face amount outstanding on the day the fee is
calculated. If there is a default under this Agreement, at the Bank’s option, the amount of the fee shall be increased to 1.5% per annum, effective starting on the day the Bank provides notice of the increase to the Borrower. 

 

	3.	OPTIONAL INTEREST RATES 

  

	 	3.1	Optional Rates. 

 The optional
interest rate is a rate per annum. Interest will be paid on the dates set forth in Section 2.3(a). No Portion will be converted to a different interest rate during the applicable interest period. Upon the occurrence of an event of default under
this Agreement, the Bank may terminate the availability of the optional interest rate for interest periods commencing after the default occurs. At the end of any interest period, the interest rate will revert to the rate stated in Section 2.4
above, unless the Borrower has designated the optional interest rate for the Portion. 
  

	 	3.2	LIBOR Rate. 

 The election of LIBOR
Rates shall be subject to the following terms and requirements: 
 (a) The interest period during which the LIBOR Rate will be
in effect will be one, two, three or six months. The first day of the interest period must be a day other than a Saturday or a Sunday on which banks are open for business in New York and London and dealing in offshore dollars (a “LIBOR
Banking Day”). The last day of the interest period and the actual number of days during the interest period will be determined by the Bank using the practices of the London inter-bank market. 
 (b) Each LIBOR Rate Portion will be for an amount not less than One Hundred Thousand Dollars ($100,000). 
 (c) The “LIBOR Rate” means the interest rate determined by the following formula. (All amounts in the calculation will be
determined by the Bank as of the first day of the interest period.) 
  

					
		 	LIBOR Rate =	 	London Inter-Bank Offered Rate
		 		 	(1.00 - Reserve Percentage)

 Where, 
 (i) “London Inter-Bank Offered Rate” means, for any applicable interest period, the rate per annum equal to the British
Bankers Association LIBOR Rate (“BBA LIBOR”), as published by Reuters (or other commercially available source providing quotations of BBA LIBOR as selected by the Bank from time to time) at approximately 11:00 a.m. London time two
(2) London Banking Days before the commencement of the interest period, for U.S. Dollar deposits (for delivery on the first day of such interest period) with a term equivalent to such interest period. If such rate is not available at such
time for any reason, then the rate for that interest period will be determined by such alternate method as reasonably selected by the Bank. A “London Banking Day” is a day on which banks in London are open for business and dealing in
offshore dollars. 
 (ii) “Reserve Percentage” means the total of the maximum reserve percentages for
determining the reserves to be maintained by member banks of the Federal Reserve System for 

  

 11 

 
Eurocurrency Liabilities, as defined in Federal Reserve Board Regulation D, rounded upward to the nearest 1/100 of one percent. The percentage will be
expressed as a decimal, and will include, but not be limited to, marginal, emergency, supplemental, special, and other reserve percentages. 
 (d) The Borrower shall irrevocably request a LIBOR Rate Portion no later than 2:00 p.m. Central time on the LIBOR Banking Day preceding the day on which the London Inter-Bank Offered Rate will be set, as specified
above. For example, if there are no intervening holidays or weekend days in any of the relevant locations, the request must be made at least three days before the LIBOR Rate takes effect. 
 (e) The Bank will have no obligation to accept an election for a LIBOR Rate Portion if any of the following described events has occurred
and is continuing: 
 (i) Dollar deposits in the principal amount, and for periods equal to the interest period, of a LIBOR
Rate Portion are not available in the London inter-bank market; or 
 (ii) the LIBOR Rate does not accurately reflect the cost
of a LIBOR Rate Portion. 
 (f) Each prepayment of a LIBOR Rate Portion, whether voluntary, by reason of acceleration or
otherwise, will be accompanied by the amount of accrued interest on the amount prepaid and a prepayment fee as described below. A “prepayment” is a payment of an amount on a date earlier than the scheduled payment date for such
amount as required by this Agreement. 
 (g) The prepayment fee shall be in an amount sufficient to compensate the Bank for
any loss, cost or expense incurred by it as a result of the prepayment, including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Portion or from fees
payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by the Bank in connection with the foregoing. For purposes of this paragraph, the Bank shall be deemed to
have funded each Portion by a matching deposit or other borrowing in the applicable interbank market, whether or not such Portion was in fact so funded. 
  

	4.	FEES AND EXPENSES 

  

	 	4.1	Fees. 

 (a) Ex-Im Bank Fee.

Bank at the time the Borrower requests the waiver or amendment. Nothing in this paragraph shall imply that the Bank is obligated to agree to any waiver or amendment requested by the Borrower. The Bank may impose additional requirements as a
condition to any waiver or amendment. 
  

	 	4.2	Expenses. 

 The Borrower agrees to
immediately repay the Bank for expenses that include, but are not limited to, filing, recording and search fees, and documentation fees.

Borrower agrees to reimburse the Bank for any reasonable expenses it incurs in the preparation of this Agreement and any agreement or instrument required by this Agreement.

of the Borrower’s books, records and collateral, and appraisals of the collateral, at such intervals as the Bank may reasonably require, provided, however, that as long as the Borrower provides the Bank with the financial statements required by
Section 9.3(a), the Borrower shall not be required to reimburse the Bank for more than one such examination during a calendar year. The actions described in this paragraph may be performed by employees of the Bank or by independent appraisers
as permitted by Ex-Im Bank. 
  

	 	4.4	No Excess Fees. 

 Notwithstanding
anything to the contrary in this Article 4, in no event shall any sum payable under this Article 4 (to the extent, if any, constituting interest under applicable laws), together with all other amounts constituting interest under applicable laws and
payable in connection with the credit evidenced hereby, exceed the amount of interest computed at the Maximum Rate. 
  

	5.	COLLATERAL 

 The property listed below now owned or owned
in the future by the parties listed below will secure the Borrower’s obligations to the Bank under the Ex-Im Line, or if the collateral is owned by a guarantor, will secure the guaranty, if so indicated in the security agreement. The collateral
is further defined in security agreement(s) executed by the owners of the collateral. “Collateral” means: 
 (a) Export-Related Inventory owned by the Borrower. 
 (b) Export-Related Accounts Receivables owned by the Borrower.

 (c) Export-Related General Intangibles owned by the Borrower. 
  

	6.	DISBURSEMENTS, PAYMENTS AND COSTS 

  

	 	6.1	Disbursements and Payments. 

 (a)
Each payment by the Borrower will be made in Dollars and immediately available funds by mail to the address shown on the Borrower’s statement or at one of the Bank’s banking centers in the United States. 
 (b) Each disbursement by the Bank and each payment by the Borrower will be evidenced by records kept by the Bank. In addition, the Bank
may, at its discretion, require the Borrower to sign one or more promissory notes. 
  

	 	6.2	Requests for Credit; Equal Access by all Borrowers. 

 Any Borrower (or a person or persons authorized by any one of the Borrowers), acting alone, can borrow up to the full amount of credit provided under this Agreement. Each Borrower will be liable for all extensions of credit made under this
Agreement to any other Borrower. 
  

	 	6.3	Telephone and Telefax Authorization. 

 a) The Bank may honor telephone or telefax instructions or email instructions containing an electronic signature for advances or repayments or for the designation of optional interest rates and telefax requests for the issuance of letters
of credit given, or purported to be given, by any one of the individuals authorized to sign loan agreements on behalf of the Borrower, or any other individual designated by any one of such authorized signers. 
 (b) Advances will be deposited in and repayments will be withdrawn from the Borrower’s account with the Bank as designated in writing
by the Borrower. 
  

 13 

 (c) The Borrower will indemnify and hold the Bank harmless from all liability, loss, and
costs in connection with any act resulting from telephone or telefax instructions the Bank reasonably believes are made by any individual authorized by the Borrower to give such instructions. This paragraph will survive this Agreement’s
termination, and will benefit the Bank and its officers, employees, and agents. 
  

	 	6.4	Pre-Billing. 

 (a) Prior to the date
each payment of principal and interest and any fees from the Borrower becomes due (the “Due Date”), the Bank will mail to the Borrower a statement of the amounts that will be due on that Due Date (the “Billed Amount”). The bill
will be mailed a specified number of calendar days prior to the Due Date, which number of days will be mutually agreed from time to time by the Bank and the Borrower. The calculations in the bill will be made on the assumption that no new extensions
of credit or payments will be made between the date of the billing statement and the Due Date, and that there will be no changes in the applicable interest rate. 
 (c) The Borrower shall make payment to the Bank for the Billed Amount, regardless of the actual amount due on that date (the “Accrued
Amount”). If the Billed Amount differs from the Accrued Amount, the discrepancy will be treated as follows: 
 (i) If the
Billed Amount is less than the Accrued Amount, the Billed Amount for the following Due Date will be increased by the amount of the discrepancy. The Borrower will not be in default by reason of any such discrepancy. 
 (ii) If the Billed Amount is more than the Accrued Amount, the Billed Amount for the following Due Date will be decreased by the amount of
the discrepancy. 
 Regardless of any such discrepancy, interest will continue to accrue based on the actual amount of
principal outstanding without compounding. The Bank will not pay the Borrower interest on any overpayment. 
  

	 	6.5	Banking Days. 

 Unless otherwise provided in this
Agreement, a banking day is a day other than a Saturday, Sunday or other day on which commercial banks are authorized to close, or are in fact closed, in the state of Texas, and, if such day relates to amounts bearing interest at an offshore rate
(if any), means any such day on which dealings in dollar deposits are conducted among banks in the offshore dollar interbank market. All payments and disbursements which would be due on a day which is not a banking day will be due on the next
banking day. All payments received on a day which is not a banking day will be applied to the credit on the next banking day. 
  

	 	6.6	Interest Calculation. 

 Except as otherwise stated
in this Agreement, all interest and fees, if any, will be computed on the basis of a 360-day year and the actual number of days elapsed. This results in more interest or a higher fee than if a 365-day year is used. Principal amounts which are not
paid when due under this Agreement shall continue to bear interest until paid. 
  

	 	6.7	Default Rate. 

 Upon the occurrence of any default
and after any applicable cure period, or after maturity or after judgment has been rendered on any obligation under this Agreement, all amounts outstanding under this Agreement, including any interest, fees, or costs which are not paid when due,
will at the option of the Bank bear interest at a rate which is the lesser of (i) the Maximum Rate or (ii) 2.0 percentage point(s) higher than the rate of interest otherwise provided under this Agreement. This may result in compounding of
interest. This will not constitute a waiver of any default. 
  

 14 

	 	6.8	Taxes. 

 (a) If any payments to the
Bank under this Agreement are made from outside the United States, the Borrower will not deduct any foreign taxes from any payments it makes to the Bank. If any such taxes are imposed on any payments made by the Borrower (including payments under
this paragraph), the Borrower will pay the taxes and will also pay to the Bank, at the time interest is paid, any additional amount which the Bank specifies as necessary to preserve the after-tax yield the Bank would have received if such taxes had
not been imposed. The Borrower will confirm that it has paid the taxes by giving the Bank official tax receipts (or notarized copies) within thirty (30) days after the due date. 
 (b) Payments made by the Borrower to the Bank will be made without deduction of United States withholding or similar taxes. If the
Borrower is required to pay U.S. withholding taxes, the Borrower will pay such taxes in addition to the amounts due to the Bank under this Agreement. If the Borrower fails to make such tax payments when due, the Borrower indemnifies the Bank against
any liability for such taxes, as well as for any related interest, expenses, additions to tax, or penalties asserted against or suffered by the Bank with respect to such taxes. 
  

	 	6.9	Payments in Kind. 

 After an event of default under
the Ex-Im Line, if the Bank requires delivery in kind of the proceeds of collection of the Borrower’s accounts receivable, such proceeds shall be credited (a) first, to interest then due and payable, (b) second, to any outstanding
principal at such time, (c) third, to other sums owed to the Bank under this Agreement at such time and (d) fourth to the Borrower. All such credits will be conditioned upon collection and any returned items may, at the Bank’s option,
be charged to the Borrower. 
  

	7.	CONDITIONS

	 	12.7	Texas Law. 

 This Agreement is governed by Texas
law. It is the intention of the parties to comply with applicable usury laws. The parties agree that the total amount of interest contracted for, charged, collected or received by the Bank under this Agreement shall not exceed the Maximum Rate. To
the extent, if any, that Chapter 303 of the Texas Finance Code (the “Code”) is relevant to the Bank for purposes of determining the Maximum Rate, the parties elect to determine the Maximum Rate under the Code pursuant to the
“weekly ceiling” from time to time in effect, as referred to and defined in § 303.001-303.016 of the Code; subject, however, to any right the Bank subsequently may have under applicable law to change the method of determining the
Maximum Rate. Notwithstanding any contrary provisions contained herein, (a) the Maximum Rate shall be calculated on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be; (b) in determining
whether the interest hereunder exceeds interest at the Maximum Rate, the total amount of interest shall be spread throughout the entire term of this Agreement until its payment in full; (c) if at any time the interest rate chargeable under this
Agreement would exceed the Maximum Rate, thereby causing the interest payable under this Agreement to be limited to the Maximum Rate, then any subsequent reductions in the interest rate(s) shall not reduce the rate of interest charged under this
Agreement below the Maximum Rate until the total amount of interest accrued from and after the date of this Agreement equals the amount of interest which would have accrued if the interest rate(s) had at all times been in effect; (d) if the
Bank ever charges or receives anything of value which is deemed to be interest under applicable Texas law, and if the occurrence of any event, including acceleration of maturity of obligations owing to the Bank, should cause such interest to exceed
the maximum lawful amount, any amount which exceeds interest at the Maximum Rate shall be applied to the reduction of the unpaid principal balance under this Agreement or any other indebtedness owed to the Bank by the Borrower, and if this Agreement
and such other indebtedness are paid in full, any remaining excess shall be paid to the Borrower; and (e) Chapter 346 of the Code shall not be applicable to this Agreement or the indebtedness outstanding hereunder.

	 	12.9	Waiver of Jury Trial. 

 THE BORROWER AND THE BANK
EACH WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS (A) UNDER THIS AGREEMENT OR ANY RELATED AGREEMENT OR UNDER ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE
FUTURE BE DELIVERED IN CONNECTION WITH THIS AGREEMENT OR (B) ARISING FROM ANY BANKING RELATIONSHIP EXISTING IN CONNECTION WITH THIS AGREEMENT, AND AGREES THAT ANY SUCH ACTION OR PROCEEDING WILL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. THE
BORROWER AGREES THAT IT WILL NOT ASSERT ANY CLAIM AGAINST THE BANK OR ANY OTHER PERSON INDEMNIFIED UNDER THIS AGREEMENT ON ANY THEORY OF LIABILITY FOR SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL OR PUNITIVE DAMAGES. 
  

	 	12.10	Successors and Assigns. 

 This Agreement is binding
on the Borrower’s and the Bank’s successors and assignees. The Borrower agrees that it may not assign this Agreement without the Bank’s prior consent. The Bank may sell participations in or assign this loan and any credit facilities
hereunder, and may exchange information about the Borrower (including, without limitation, any information regarding any hazardous substances) with actual or potential participants or assignees, including without limitation Ex-Im Bank. If a
participation is sold or the loan is assigned, the purchaser will have the right of set-off against the Borrower. 
  

	 	12.11	Severability; Waivers. 

 (a) Should any clause,
sentence, paragraph or Section of this Agreement be judicially declared to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the
part or parts of this Agreement so held to be invalid, unenforceable or void will be deemed to have been stricken herefrom and the remainder will have the same force and effectiveness as if such part or parts had never been included herein.

 (b) No failure or delay on the part of the Bank in exercising any power or right hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No course of
dealing between any Borrower or any subsidiary of such Borrower, and the Bank shall operate as a waiver of any right of the Bank. No modification or waiver of any provision of this Agreement, nor consent to any departure by the Borrowers therefrom
shall in any event be effective unless the same shall be in writing, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Except as otherwise provided by this Agreement or applicable
law, no notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances. 
  

	 	12.12	Attorneys’ Fees. 

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

 27 

	 	12.13	Joint and Several Liability. 

 (a)
Each Borrower agrees that it is jointly and severally liable to the Bank for the payment of all obligations arising under this Agreement, and that such liability is independent of the obligations of the other Borrower(s). Each obligation, promise,
covenant, representation and warranty in this Agreement shall be deemed to have been made by, and be binding upon, each Borrower, unless this Agreement expressly provides otherwise. The Bank may bring an action against any Borrower, whether an
action is brought against the other Borrower(s). 
 (b) Each Borrower agrees that any release which may be given by the Bank
to the other Borrower(s) or any guarantor will not release such Borrower from its obligations under this Agreement. 
 (c)
Each Borrower waives any right to assert against the Bank any defense, setoff, counterclaim, or claims which such Borrower may have against the other Borrower(s) or any other party liable to the Bank for the obligations of the Borrowers under this
Agreement. 
 (d) Each Borrower waives any defense by reason of any other Borrower’s or any other person’s defense,
disability, or release from liability. The Bank can exercise its rights against each Borrower even if any other Borrower or any other person no longer is liable because of a statute of limitations or for other reasons. 
 (e) Each Borrower agrees that it is solely responsible for keeping itself informed as to the financial condition of the other Borrower(s)
and of all circumstances which bear upon the risk of nonpayment. Each Borrower waives any right it may have to require the Bank to disclose to such Borrower any information which the Bank may now or hereafter acquire concerning the financial
condition of the other Borrower(s). 
 (f) Each Borrower waives all rights to notices of default or nonperformance by any
other Borrower under this Agreement. Each Borrower further waives all rights to notices of the existence or the creation of new indebtedness by any other Borrower and all rights to any other notices to any party liable on any of the credit extended
under this Agreement. 
 (g) The Borrowers represent and warrant to the Bank that each will derive benefit, directly and
indirectly, from the collective administration and availability of credit under this Agreement. The Borrowers agree that the Bank will not be required to inquire as to the disposition by any Borrower of funds disbursed in accordance with the terms
of this Agreement. 
 (h) Until all obligations of the Borrowers to the Bank under this Agreement have been paid in full and
any commitments of the Bank or facilities provided by the Bank under this Agreement have been terminated, each Borrower (a) waives any right of subrogation, reimbursement, indemnification and contribution (contractual, statutory or otherwise),
including without limitation, any claim or right of subrogation under the Bankruptcy Code (Title 11, United States Code) or any successor statute, which such Borrower may now or hereafter have against any other Borrower with respect to the
indebtedness incurred under this Agreement; and (b) waives any right to enforce any remedy which the Bank now has or may hereafter have against any other Borrower, and waives any benefit of, and any right to participate in, any security now or
hereafter held by the Bank. 
 (i) Each Borrower waives any right to require the Bank to proceed against any other Borrower or
any other person; proceed against or exhaust any security; or pursue any other remedy. Further, each Borrower consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of the Borrowers under
this Agreement or which, but for this provision, might operate as a discharge of the Borrowers. 
  

 28 

	 	12.14	One Agreement. 

 This Agreement and any related
security or other agreements required by this Agreement, collectively: 
 (a) represent the sum of the understandings and
agreements between the Bank and the Borrower concerning this credit; 
 (b) replace any prior oral or written agreements
between the Bank and the Borrower concerning this credit; and 
 (c) are intended by the Bank and the Borrower as the final,
complete and exclusive statement of the terms agreed to by them. 
 In the event of any conflict between this Agreement and any other
agreements required by this Agreement, this Agreement will prevail. Any reference in any related document to a “promissory note” or a “note” executed by the Borrower and dated as of the date of this Agreement shall be deemed to
refer to this Agreement, as now in effect or as hereafter amended, renewed, or restated. 
  

	 	12.15	Notices. 

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

	 	12.16	Headings. 

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

	 	12.17	Counterparts. 

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

 

	 	12.18	Commitment Expiration. 

 The Bank’s commitment
to extend credit under this Agreement will expire on June 30, 2007, unless this Agreement and any documents required by this Agreement have been signed and returned to the Bank on or before that date. 
  

	 	12.19	USA Patriot Act Notice. 

 Federal law requires all
financial institutions to obtain, verify and record information that identifies each person who opens an account or obtains a loan. The Bank will ask for the Borrower’s legal name, address, tax ID number or social security number and other
identifying information. The Bank may also ask for additional information or documentation or take other actions reasonably necessary to verify the identity of the Borrower, guarantors or other related persons. 
  

 29 

	 	12.20	Notice of Final Agreement.

the Collateral. 
 (g) All books and records specifically pertaining to any Collateral, including but not limited to any
computer-readable memory and any computer hardware or software necessary to process such memory (“Books and Records”). 
 2.
THE INDEBTEDNESS. The Collateral secures and will secure all Indebtedness of the Pledgor to the Bank. Each party obligated under any Indebtedness is referred to in this Agreement as a “Debtor.” “Indebtedness” means, with
respect to that certain $10,000,000 Ex-Im Bank guaranteed revolving line of credit arising under that certain Loan Agreement (Ex-Im Bank Guaranteed Revolving Line of Credit) (the “Loan Agreement”) and related agreements, documents
and instruments entered into between Bank and Pledgor as of even date herewith, as now in effect and as amended, renewed or restated in the future, all debts, obligations or liabilities now or hereafter existing, absolute or contingent of the Debtor
or any one or more of them to the Bank, whether voluntary or involuntary, whether due or not due, or whether incurred directly or indirectly or acquired by the Bank by assignment or otherwise.

 3. PLEDGOR’S COVENANTS. The Pledgor represents, covenants and warrants that unless compliance is
waived by the Bank in writing: 
 (a) The Pledgor will properly preserve the Collateral; defend the Collateral against any
adverse claims and demands; and keep accurate Books and Records. 
 (b) The Pledgor’s chief executive office is located,
in the state specified on the signature page hereof. In addition, the Pledgor is incorporated in or organized under the laws of the state specified on such signature page. The Pledgor shall give the Bank at least thirty (30) days notice before
changing its chief executive office or state of incorporation or organization. The Pledgor will notify the Bank in writing prior to any change in the location of any Collateral. 
 (c) The Pledgor will notify the Bank in writing prior to any change in the Pledgor’s name, identity or business structure.

 (d) Except for Permitted Liens (as defined in the Loan Agreement), the Pledgor has not granted and will not grant any
security interest in any of the Collateral except to the Bank, and will keep the Collateral free of all liens, claims, security interests and encumbrances of any kind or nature except the security interest of the Bank. 
 (e) The Pledgor will promptly notify the Bank in writing of any event which affects the value of the Collateral, the ability of the
Pledgor or the Bank to dispose of the Collateral, or the rights and remedies of the Bank in relation thereto, including, but not limited to, the levy of any legal process against any Collateral and the adoption of any marketing order, arrangement or
procedure affecting the Collateral, whether governmental or otherwise. 
 (f) The Pledgor shall pay all costs necessary to
preserve, defend, enforce and collect the Collateral, including but not limited to taxes, assessments, insurance premiums, repairs, rent, storage costs and expenses of sales, and any costs to perfect the Bank’s security interest (collectively,
the “Collateral Costs”). Without waiving the Pledgor’s default for failure to make any such payment and upon prior written notice to the Pledgor, the Bank at its option may pay any such Collateral Costs, and discharge
encumbrances on the Collateral, and such Collateral Costs payments shall be a part of the Indebtedness and bear interest at the rate set out in the Indebtedness. The Pledgor agrees to reimburse the Bank on demand for any Collateral Costs so
incurred. 
 (g) Until the Bank exercises its rights to make collection, the Pledgor will diligently collect all Collateral.

 (h) If any Collateral is or becomes the subject of any registration certificate, certificate of deposit or negotiable
document of title, including any warehouse receipt or bill of lading, the Pledgor shall immediately deliver such document to the Bank, together with any necessary endorsements. 
 (i) The Pledgor will not sell, lease, agree to sell or lease, or otherwise dispose of any Export-Related Accounts Receivable and
Export-Related Inventory except with the prior written consent of the Bank or as otherwise set forth in the Loan Agreement; provided, however, that the Pledgor may sell Export-Related Inventory in the ordinary course of business. 
 (j) The Pledgor will maintain and keep in force insurance covering the Collateral against property damage, to the extent that any
Collateral is of a type which can be so insured. Such insurance shall be with responsible companies in such amounts, with such deductibles and against such risks as are usually carried by owners of similar businesses and properties in the same
general areas in which the Pledgor operates, and the Pledgor shall furnish to the Bank satisfactory evidence thereof promptly upon request. The Pledgor shall provide the Bank with a certificate showing coverage provided under the policies of
insurance and such policies shall be endorsed to the effect that they will not be canceled for nonpayment of premium, reduced or affected in any material manner without thirty (30) days prior written notice to the Bank.

 Security Agreement (Ex-Im Line) 

 (k) The Pledgor will, at its expense, diligently prosecute all patent, trademark or
service mark or copyright applications pending on or after the date hereof, will maintain in effect all issued patents and will renew all trademark and service mark registrations, including payment of any and all maintenance and renewal fees
relating thereto, except for such patents, service marks and trademarks that are being sold, donated or abandoned by the Pledgor pursuant to the terms of its intellectual property management program. The Pledgor also will promptly make application
on any patentable but unpatented inventions, registerable but unregistered trademarks and service marks, and copyrightable but uncopyrighted works. The Pledgor will at its expense protect and defend all rights in the Collateral against any material
claims and demands of all persons other than the Bank and will, at its expense, enforce all rights in the Collateral against any and all infringers of the Collateral where such infringement would materially impair the value or use of the Collateral
to the Pledgor or the Bank. The Pledgor will not license or transfer any of the Collateral, except for such licenses as are customary in the ordinary course of the Pledgor’s business, or except with the Bank’s prior written consent.

to assign to the Bank the proceeds of any such letters of credit. 
 (d) Notify any account debtors, any buyers of the
Collateral, or any other persons of the Bank’s interest in the Collateral. 
 5. DEFAULTS. Any one or more of the following shall be a

 (c) The Bank fails to have an enforceable first lien (except for any prior liens to which
the Bank has consented in writing or “Permitted Liens” as defined in the Loan Agreement) on or security interest in the Collateral. 
 (d) Any custodian, receiver or trustee is appointed to take possession, custody or control of all or a substantial portion of the property of the Pledgor or of any guarantor or other party obligated under any

guarantor or other party obligated under any Indebtedness under any bankruptcy or other law for the relief of, or relating to, debtors.

be expected to have a Material Adverse Effect (as defined in the Loan Agreement).

without notice or demand. 
 (b) Enforce the security interest given hereunder pursuant to the Uniform Commercial Code and any

 (e) Require the Pledgor to direct all account debtors to forward all payments and proceeds of the Collateral to a post office box under the Bank’s exclusive control. 
 (f) Require the Pledgor to assemble the Collateral, including the Books and Records, and make them available to the Bank at a place

 (g) Enter upon the property where any Collateral, including any Books and Records, are located and

hold, preserve, process, assemble, prepare for sale or lease, market for sale or lease, sell or lease, or otherwise dispose of, any Collateral. 
 (h) Demand and collect any payments on and proceeds of the Collateral. In connection therewith the Pledgor irrevocably authorizes the Bank to endorse or sign the Pledgor’s name on all checks, drafts, collections,
receipts and other documents, and to take possession of and open the mail addressed to the Pledgor and remove therefrom any payments and proceeds of the Collateral. 
 (i) Grant extensions and compromise or settle claims with respect to the Collateral for less than face value, all without prior notice to

hereafter acquired by the Pledgor, if the Bank deems such use or transfer necessary or advisable in order to take possession of, hold, preserve, process, assemble, prepare for sale or lease, market for sale or lease, sell or lease, or otherwise
dispose of, any Collateral. The Pledgor agrees that any such use or transfer shall be without any additional consideration to the Pledgor. As used in this paragraph, “Intellectual Property” includes, but is not limited to, all trade
secrets, computer software, service marks, trademarks, trade names, trade styles, copyrights, patents, applications for any of the foregoing, customer lists, working drawings, instructional manuals, and rights in processes for technical
manufacturing, packaging and labeling, in which the Pledgor has any right or interest, whether by ownership, license, contract or otherwise.

to pay immediately the costs and expenses thereof, together with reasonable attorney’s fees to the extent permitted by law. 
 (h) In the event the Bank seeks to take possession of any or all of the Collateral by judicial process, the Pledgor hereby irrevocably waives any bonds and any surety or security relating thereto that may be required by applicable law as an
incident to such possession, and waives any demand for possession prior to the commencement of any such suit or action. 
 (i)
This Agreement shall constitute a continuing agreement, applying to all future as well as existing transactions, whether or not of the character contemplated at the date of this Agreement, and if all transactions between the Bank and the Pledgor
