A certificate of Lender claiming entitlement to payment as set forth above shall be conclusive in the absence of manifest error. Such certificate shall set forth the nature of the occurrence giving rise to such

reduction, the amount of such charge to be paid to Lender, and the method by which such amount was determined. In determining such amount, such Lender may use any reasonable averaging and attribution method, applied on a non-discriminatory basis.

All of the Indebtedness evidenced by the Revolving Note which is not part of a LIBOR Portion shall constitute a single Prime Rate Portion (a “Prime Rate Revolving Portion”) and all of the Indebtedness evidenced by the Revolving Note which bears interest with reference to a particular LIBOR for a particular Interest Period shall constitute a single LIBOR Portion (a “LIBOR Revolving Portion”). There shall not be more than four (4) LIBOR Portions applicable to the Note outstanding at any one time. Anything contained herein to the contrary notwithstanding, the obligation of the Lender to create, continue or effect by conversion any LIBOR Portion shall be conditioned upon the fact that at the time no Default or Event of Default shall have occurred and be continuing. The Borrowers hereby promise to pay interest on the applicable Portions at the rates and times specified in this Section 2.8.

     (b) The Prime Rate Portions shall bear interest at the rate per annum determined by adding the Applicable Prime Rate Margin then in effect in accordance with the definition of Applicable Percentage to the Prime Rate as in effect from time to time.

Interest on the Prime Rate Portions shall be payable monthly in arrears on the first day of each month in each year (commencing April 1, 2006) and at maturity or prepayment of the Note, and interest after maturity (whether by lapse of time, acceleration or otherwise) shall be due and payable upon demand. Any change in the interest rate on the Prime Rate Portions resulting from a change in the Prime Rate shall be effective on the date of the relevant change in the Prime Rate.

     (c) Each LIBOR Portion shall bear interest for each Interest Period selected therefor at a rate per annum determined by adding the Applicable LIBOR Margin then in effect in accordance with the definition of Applicable Percentage to the LIBOR for such Interest Period. If an Event of Default occurs and is then continuing, effective at the end of each then existing Interest Period, each then existing LIBOR Portion shall automatically be converted into and added to an appropriate Prime Rate Portion and shall thereafter bear interest at the interest rate applicable to such Prime Rate Portion unless and until converted in accordance with the terms hereof. Interest on the LIBOR Portions shall be computed on the basis of actual days elapsed in a 360-day year. Interest on each LIBOR Portion shall be due and payable in arrears on the first

day of each month, on the last day of each Interest Period applicable thereto, and at maturity or prepayment of the Note, and interest after maturity (whether by lapse of time, acceleration or otherwise) shall be due and payable upon demand. The Borrowers shall notify the Lender on or before 11:00 a.m. (St. Louis, Missouri time) on the third Banking Day preceding the end of an Interest Period applicable to a LIBOR Portion whether such LIBOR Portion is to continue as a LIBOR Portion, in which event the Borrowers shall notify the Lender of the new Interest Period selected therefor, and in the event the Borrowers shall fail to so notify the Lender, such LIBOR Portion shall automatically be converted into and added to the applicable Prime Rate Portion as of and on the last day of such Interest Period.

     (d) Each LIBOR Portion shall be in an amount equal to $250,000 or such greater amount which is an integral multiple of $50,000.

     (e) The Borrowers shall notify the Lender by 11:00 a.m. (St. Louis, Missouri time) at least three Banking Days prior to the date upon which the Borrowers request that any LIBOR Portion be created or that any part of a Prime Rate Portion be converted into a LIBOR Portion (each such notice to specify in each instance the amount thereof and the Interest Period selected therefor). If any request is made to convert a LIBOR Portion into another type of Portion available hereunder, such conversion shall only be made so as to become effective as of the last day of the Interest Period applicable thereto. All requests for the creation, continuance and conversion of Portions under this Agreement shall be irrevocable. Such requests may be in writing or by telephone and shall be made by (i) any officer of the requesting Borrower; or (ii) any person designated as such Borrower’s agent by any officer of the Borrower in a writing delivered to the Lender; or (iii) any person reasonably believed by the Lender to be an officer of such Borrower or such a designated agent.

     (f) Notwithstanding anything to the contrary contained herein, (i) from and after the date of the occurrence of any Default or Event of Default, in the Lender’s discretion, the principal amount of the Advances, outstanding from time to time shall bear interest at the Default Rate; and (ii) during any period that the sum of the outstanding principal balance of all Advances exceeds the sum of the Borrowing Base, the L/C Amount and reserves imposed pursuant to Section 2.1 hereof, if any, the principal of the Advances shall automatically bear interest at the Default Rate; and provided, further, that in any event no rate change shall be put into effect which would result in a rate greater than the highest rate permitted by law.

     (g) Notwithstanding any other provision of this Agreement or the Note, if at any time the Lender shall determine that any change in applicable laws, treaties or regulations or in the interpretation thereof by any court or governmental authority charged with the administration thereof makes it unlawful, as a result of compliance by the Lender in good faith with such laws, treaties, regulations or interpretations thereof, for the Lender to create or continue to maintain any LIBOR Portion, it shall promptly so notify the Borrowers and the obligation of the Lender to create, continue or maintain any such LIBOR Portion under this Agreement shall terminate until it is no longer unlawful for the Lender to create, continue or maintain such LIBOR Portion. The Borrowers, on demand, shall, if the continued maintenance of any such LIBOR Portion is unlawful, thereupon prepay the outstanding principal amount of the affected LIBOR Portion, together with all interest accrued thereon and all other amounts payable to the Lender with respect thereto under this Agreement; provided, however, that the Borrowers may elect to

convert the principal amount of the affected Portion into another type of Portion available hereunder, subject to the terms and conditions of this Agreement.

     (h) Notwithstanding any other provision of this Agreement or the Note, if prior to the commencement of any Interest Period, the Lender shall determine that deposits in the amount of any LIBOR Portion scheduled to be outstanding during such Interest Period are not generally available in the relevant market or, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining LIBOR, then the Lender shall promptly give notice thereof to the Borrowers and the obligations of the Lender to create, continue or effect by conversion any such LIBOR Portion in such amount and for such Interest Period shall terminate until deposits in such amount and for the Interest Period selected by the Borrowers shall again be generally available in the relevant market and adequate and reasonable means exist for ascertaining LIBOR.

     (i) With respect to any LIBOR Portion, if the Lender shall determine that any change in any applicable law, treaty, regulation or guideline (including, without limitation, Regulation D of the Board of Governors of the Federal Reserve System) or any new law, treaty, regulation or guideline, or any interpretation of any of the foregoing by any governmental authority charged with the administration thereof or any central bank or other fiscal, monetary or other authority having jurisdiction over the Lender or its lending branch or the LIBOR Portions contemplated by this Agreement (whether or not having the force of law), shall:

          (i) impose, increase, or deem applicable any reserve, special deposit or similar requirement against assets held by, or deposits in or for the account of, or loans by, or any other acquisition of funds or disbursements by, the Lender which is not in any instance already accounted for in computing the interest rate applicable to such LIBOR Portion;

          (ii) subject the Lender, any LIBOR Portion or any of the Note to the extent it evidences such a LIBOR Portion to any tax (including, without limitation, any United States interest equalization tax or similar tax however named applicable to the acquisition or holding of debt obligations and any interest or penalties with respect thereto), duty, charge, stamp tax, fee, deduction or withholding in respect of this Agreement, any LIBOR Portion or any of the Note to the extent it evidences such a LIBOR Portion, except such taxes as may be measured by the overall net income or gross receipts of the Lender or its lending branches and imposed by the jurisdiction, or any political subdivision, or taxing authority thereof, in which the Lender’s principal executive office or its lending branch is located;

          (iii) change the basis of taxation of payments of principal and interest due from the Borrowers to the Lender hereunder or under any of the Note to the extent it evidences any LIBOR Portion (other than by a change in taxation of the overall net income or gross receipts of the Lender); or

          (iv) impose on the Lender any penalty with respect to the foregoing or any other condition regarding this Agreement, any LIBOR Portion, or its disbursement, or any of the Note to the extent it evidences any LIBOR Portion;

14

and the Lender shall determine that the result of any of the foregoing is to increase the cost (whether by incurring a cost or adding to a cost) to the Lender of creating or maintaining any LIBOR Portion hereunder or to reduce the amount of principal or interest received or receivable by the Lender, Lender shall promptly advise the Borrowers of the foregoing and then the Borrowers shall pay to the Lender, within fifteen (15) days after demand therefor by the Lender, such additional amounts as the Lender shall reasonably determine are sufficient to compensate and indemnify it for such increased cost or reduced amount.

     (j) In the event the Lender shall incur any loss, cost or expense (including, without limitation, any loss (including loss of profit), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired or contracted to be acquired by the Lender to fund or maintain any LIBOR Portion or the relending or reinvesting of such deposits or other funds or amounts paid or prepaid to the Lender) as a result of:

     (i) any payment of a LIBOR Portion on a date other than the last day of the then applicable Interest Period for any reason, whether before or after an Event of Default or Default, and whether or not such payment is required by any provisions of this Agreement; or

     (ii) any failure by the Borrowers to create, borrow, continue or effect by conversion a LIBOR Portion on the date specified in a notice given pursuant to this Agreement;

then within fifteen (15) days after demand therefor by the Lender, the Borrowers shall pay to the Lender such amount as will reimburse the Lender for such loss, cost or expense.

     (k) The Lender may, at its option, elect to make, fund or maintain Portions of the Loans hereunder at such of its branches or offices as the Lender may from time to time elect.

     (l) Notwithstanding any provision of this Agreement to the contrary, the Lender shall be entitled to fund and maintain its funding of all or any part of the Note in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder (including, without limitation, determinations under Sections 2.8(h), (i) and (j) hereof) shall be made as if the Lender had actually funded and maintained each LIBOR Portion during each Interest Period applicable thereto through the purchase of deposits in the relevant market in the amount of such LIBOR Portion, having a maturity corresponding to such Interest Period, and, in the case of any LIBOR Portion, bearing an interest rate equal to the LIBOR, as the case may be, for such Interest Period.

     (m) If the Lender sells a participation (as opposed to a sale of a direct interest) in the Loans, no such sale will result in a change in the rate of interest being assessed against the Obligations.

     Section 2.9 Maximum Interest Rate. In no event shall any interest rate provided for hereunder exceed the maximum rate, if any, 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 which 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 under this Agreement, the total amount of interest paid or accrued under the terms of this Agreement is less than the total amount of interest which would, but for this Section 2.9, 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 difference between (a) the lesser of (i) the amount of interest which would have been charged if the Maximum Rate had, at all times, been in effect or (ii) the amount of interest which would have accrued had the interest rates otherwise set forth in this Agreement, at all times, been in effect and (b) the amount of interest actually paid or accrued under this Agreement. In the event that a court determines that the Lender has 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 Lender shall refund to the Borrowers such excess.

     Section 2.10 Voluntary Prepayment; Termination of Agreement by Borrowers; Permanent Reduction of Commitment.

     (a) Except as otherwise provided herein, the Borrowers may, in their discretion, prepay the Obligations in whole at any time or from time to time in part.

     (b) The Borrowers may at any time and from time to time, upon at least 30 days’ prior written notice to the Lender, permanently reduce in part or terminate the Revolving Loan Commitment; provided, however, that no reduction shall reduce the Revolving Loan Commitment to an amount less than the then-aggregate amount of the Advances; plus the L/C Amount.

     Section 2.11 Mandatory Prepayment. Without notice or demand and without limiting Borrowers’ obligation to pay interest at the Default Rate as required under Section 2.8(f)(i) or (ii), if the sum of the outstanding principal balance of the Advances plus the L/C Amount plus reserves imposed pursuant to Section 2.1 hereof, if any, shall at any time exceed the Borrowing Base (an “Overadvance”), the Borrowers shall (i) first, immediately prepay the Advances to the extent necessary to eliminate such excess; and (ii) if prepayment in full of the Advances is insufficient to eliminate such excess, pay to the Lender in immediately available funds for deposit in the Special Account an amount equal to the remaining excess. Any payment received by the Lender under this Section 2.11 or under Section 2.10 may be applied to the Obligation of Reimbursement, or the Advances, including interest thereon and any fees, commissions, costs and expenses required to be paid hereunder and under the Security Documents, in such order and in such amounts as the Lender, in its discretion, may from time to time determine.

     Section 2.12 Payment. All payments of principal of and interest on the Advances, the Obligation of Reimbursement, the commissions and fees hereunder and amounts required to be paid to the Lender for deposit in the Special Account shall be made to the Lender in United

States dollars constituting immediately available funds. The Borrowers hereby authorize the Lender, in its discretion at any time or from time to time and without request by the Borrowers, to make an Advance to the extent necessary to pay any such amounts and any fees, costs or expenses hereunder or under the Security Documents.

     Section 2.13 Payment on Non-Banking Days. Subject to clause (i) of the definition of Interest Period, whenever any payment to be made hereunder shall be stated to be due on a day which is not a Banking Day, such payment may be made on the next succeeding Banking Day, and such extension of time shall in such case be included in the computation of interest on the Advances or the fees hereunder, as the case may be.

     Section 2.14 Use of Proceeds. The proceeds of Advances and each Letter of Credit caused to be issued shall be used by the Borrowers for repayment of Borrowers’ prior revolving line of credit and for Capital Expenditures, stock acquisitions, permitted acquisitions and other general corporate needs.

     Section 2.15 Liability Records. The Lender may maintain from time to time, at its discretion, liability records as to any and all Advances made or repaid, interest accrued or paid under this Agreement, outstanding Letters of Credit and fees thereon and the Borrowers’ Obligation of Reimbursement. All entries made on any such record shall be presumed correct until the Borrowers establish the contrary. On demand by the Lender, the Borrowers will admit and certify in writing the exact principal balance that the Borrowers then assert to be outstanding to the Lender for Advances under this Agreement and the amount of any Letters of Credit outstanding. Any billing statement or accounting rendered by the Lender shall be presumed correct, until Borrowers establish the contrary.

     Section 2.16 Fees.

     (a) The Borrowers agree to pay the Lender a fee at the rate of the Unused Line Fee applicable at such time in accordance with the definition of Applicable Percentage on the average daily unused amount of the Revolving Loan Commitment from the date hereof to and including the date on which such facility is terminated, due and payable quarterly in arrears on the first day of each quarter, commencing April 1, 2006, provided that any such fee remaining unpaid upon termination of the total credit facility or acceleration of the Note by the Lender pursuant to Section 8.2 hereof shall be due and payable on the date of such termination or acceleration. Such fee shall be calculated on the basis of actual days elapsed in a 360-day year.

     (b) The Borrowers agree to pay the Lender a commission with respect to each Letter of Credit, if any, accruing on a daily basis and computed at the rate of two percent (2%) [per annum] of the available amount of such Letter of Credit (as it may be changed from time to time) from and including the date of issuance of such Letter of Credit until such date as such Letter of Credit is terminated, payable monthly in arrears, and prorated for any part of a full calendar month in which such Letter of Credit remains outstanding. The foregoing commission shall be in addition to any and all customary fees, commissions and charges of any Issuer of a Letter of Credit with respect to or in connection with such Letter of Credit.

2.17 Joint and Several Liability of Borrowers; Rights of Contribution among Borrowers.

     (a) Each Borrower states and acknowledges that: (1) pursuant to this Agreement, the Borrowers desire to utilize their borrowing potential on a consolidated basis to the same extent possible as if they were merged into a single corporate entity; (2) each Borrower has determined that it will benefit specifically and materially from the advances of credit contemplated by this Agreement; (3) it is both a condition precedent to the obligations of the Lender hereunder and a desire of each Borrower that each Borrower execute and deliver to Lender this Agreement; and (4) each Borrower has requested and bargained for the structure and terms of and security for the advances contemplated by this Agreement.

     (b) Each Borrower hereby irrevocably and unconditionally: (i) agrees that it is jointly and severally liable to the Lender for the full and prompt payment and performance of the Obligations and agreements of each Borrower under this Agreement and each other document related hereto that may specify that a particular Borrower is responsible for a given payment or performance; (ii) agrees to fully and promptly perform all of its obligations hereunder with respect to each advance of credit hereunder as if such advance had been made directly to it; and (iii) agrees as a primary obligation to indemnify Lender, on demand, for and against any loss incurred by Lender as a result of any Borrower being or becoming void, voidable, unenforceable or ineffective for any reason whatsoever, whether or not known to the subject Borrower or any Person, the amount of such loss being the amount which the Lender would otherwise have been entitled to recover from the Borrower.

     (c) It is the intent of each Borrower that the indebtedness, obligations and liabilities hereunder of no one of them be subject to challenge on any basis related to any federal or state law dealing with fraudulent conveyances or any other law related to transfers for less than fair or reasonably equivalent value. Accordingly, as of the date hereof, the liability of each Borrower under this Section 2.17 together with all of its other liabilities to all Persons as of the date hereof and as of any other date on which a transfer is deemed to occur by virtue of this Agreement, calculated in amount sufficient to pay its probable net liabilities on its existing indebtedness as the same become absolute and matured. (“Dated Liabilities”) is and is to be, less than the amount of the aggregate of a fair valuation of its property as of such corresponding date (“Dated Assets”). To this end, each Borrower under this Section 2.17 (i) grants to and recognizes in each other Borrower ratably, rights of subrogation and contribution in the amount, if any, by which the Dated Assets of such Borrower, but for the aggregate rights of subrogation and contribution in its favor recognized herein, would exceed the Dated Liabilities of such Borrower or, as the case may be, and (ii) acknowledges receipt of and recognizes its rights to subrogation and contribution ratably from the other Borrower in the amount, if any, by which the Dated Liabilities of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Assets of such U.S. Borrower under this Section 2.17. In recognizing the value of the Dated Assets and the Dated Liabilities, it is understood that each Borrower will recognize, to at least the same extent of their aggregate recognition of liabilities hereunder, their rights to subrogation and contribution hereunder. It is a material objective of this Section 2.17 that each Borrower recognizes rights to subrogation and contribution rather than be deemed to be insolvent (or in contemplation thereof by reason of an arbitrary interpretation of its joint and several obligations hereunder).

     2.18 Waiver of Suretyship and Other Defenses. To the extent a Borrower is deemed to be a surety, secondary obligor, endorser or accommodation party with respect to Obligations incurred under this Agreement, each Borrower waives, to the full extent permitted by applicable law, all suretyship defenses and all defenses and rights of an endorser or accommodation party provided in Section 400.3-605 of the UCC and all other defenses allowed by law provided to Persons holding such status.

ARTICLE III

Security Interest

     Section 3.1 Grant of Security Interest. The Borrowers hereby assign and grant to the Lender a lien upon and security interest (collectively referred to as the “Security Interest”) in the Collateral, as security for the payment and performance of each and every debt, liability and obligation of every type and description which the Borrowers, or any Borrower, may now or at any time hereafter owe to the Lender or to any affiliate of Lender (whether such debt, liability or obligation now exists or is hereafter created or incurred, whether it arises in a transaction involving the Lender alone, any affiliate of the Lender, or in a transaction involving other creditors of any Borrower, and whether it is direct or indirect, due or to become due, absolute or contingent, primary or secondary, liquidated or unliquidated, or sole, joint, several or joint and several, and including specifically, but not limited to, the Obligation of Reimbursement and all indebtedness of the Borrowers arising under this Agreement, the Note, any L/C Application or any other loan or credit agreement or guaranty between any Borrower and the Lender, whether now in effect or hereafter entered into; all such debts, liabilities and obligations are herein collectively referred to as the “Obligations”).

In addition to the rights of the Lender under Section 6.10 hereof, with respect to any and all rights to payment constituting Collateral, the Lender may at any time (following the occurrence of an Event of Default) notify any account debtor or other person obligated to pay the amount due that such right to payment has been assigned or transferred to the Lender for security and shall be paid directly to the Lender. The Borrowers will join in giving such notice if the Lender so requests. At any time after the Borrowers or the Lender give such notice to an account debtor or other obligor, the Lender may, but need not, in the Lender’s name or in the applicable Borrower’s name, (a) demand, ▇▇▇ for, collect or receive any money or property at any time payable or receivable on account of, or securing, any such right to payment, or grant any extension to, make any compromise or settlement with or otherwise agree to waive, modify, amend or change the obligations (including collateral obligations) of any such account debtor or other obligor; and (b) as agent and attorney in fact of such Borrower, notify the United States Postal Service to change the address for delivery of such Borrower’s mail to any address designated by the Lender, otherwise intercept such Borrower’s mail, and receive, open and dispose of such Borrower’s mail, applying all Collateral as permitted under this Agreement and holding all other mail for such Borrower’s account or forwarding such mail to such Borrower’s last known address.

     Section 3.3 Assignment of Insurance. As additional security for the payment and performance of the Obligations, the Borrowers hereby assign to the Lender any and all monies

Following the occurrence of any Event of Default, the Lender may (but need not), in the Lender’s name or in a Borrower’s name, execute and deliver proof of claim, receive all such monies, endorse checks and other instruments representing payment of such monies, and adjust, litigate, compromise or release any claim against the issuer of any such policy.

     (c) The right of the Lender to hold the Premises shall cease and terminate upon the earlier of (i) payment in full and discharge of all Obligations, and (ii) final sale or disposition of all goods constituting Collateral and delivery of all such goods to purchasers.

     (d) The Lender shall not be obligated to pay or account for any rent or other compensation for the possession, occupancy or use of any of the Premises; provided, however, in the event that the Lender does pay or account for any rent or other compensation for the possession, occupancy or use of any of the Premises, the Borrowers shall reimburse the Lender promptly for the full amount thereof. In addition, the Borrowers will pay, or reimburse the Lender for, all taxes, fees, duties, imposts, charges and expenses at any time incurred by or imposed upon the Lender by reason of the execution, delivery, existence, recordation, performance or enforcement of this Agreement or the provisions of this Section 3.4.

     Section 3.5 License. The Borrowers hereby grant to the Lender a non-exclusive, worldwide and royalty-free license or sublicense (or, to the extent Borrowers’ rights are derived from licenses from another Person, a sublicense co-extensive with Borrowers’ license rights, except to the extent prohibited by such license) to use or otherwise exploit all trademarks, franchises, trade names, copyrights and patents of the Borrowers, or used by the Borrowers under license, for the purpose of selling, leasing or otherwise disposing of any or all Collateral following an Event of Default. If required by the terms of any license agreement (a true copy of each of which the Borrowers have delivered and, regarding future agreements, will deliver to Lender), the Borrowers will cause all licensors of such rights to consent to such grant of sublicense rights to the Lender on terms acceptable to the Lender. The Borrowers hereby agree that during the term of this Agreement, neither Borrower will sell, hypothecate or allow any lien to encumber their respective patents, trademarks, trade names, trade secrets, copyrights or license rights described above.

     Section 3.6 Springing Security Interest in Intellectual Property. In conjunction with the execution of this Agreement, the Borrowers agree to deliver to Lender those certain fully executed, Patent, Trademark and License Collateral Assignment and Security Agreements attached hereto in Exhibit E dated as of the date hereof (the “IP Security Agreements”) to hold the same in trust until the IP Security Agreements are released in accordance with the terms of this Section 3.6. In conjunction with the occurrence of an Event of Default (following applicable cure periods) hereunder, Borrowers hereby agree that (i) the IP Security Agreements shall be released to the Lender, (ii) the IP Security Agreements shall be deemed in full force and effect from the date hereof and (iii) the Lender (in addition to all rights granted pursuant to the IP Security Agreements) is authorized to file in all desired federal and state recording offices such documents as are deemed appropriate by Lender, at such time, to reflect Lender’s security interest in Borrowers assets described therein, including the filing of any UCC-1 financing statements.

     Section 3.7 Security Interest in Special Account and Collateral Account. The Borrowers hereby pledge, and grant to the Lender a security interest in, all funds held in the Special Account and in the Collateral Account from time to time and all proceeds thereof, as security for the payment of all present and future Obligations of Reimbursement and all other Obligations. The Borrowers will execute and deliver to the Lender such Deposit Account control agreements as the Lender may require in its sole discretion to perfect the Lender’s security interest in the Special Account and the Collateral Account.

Borrowers will not be in violation of their maintenance obligation hereunder with respect to any Collateral, other than Inventory (as to which this sentence shall not apply in any respect), until Lender shall have given Borrowers written notice of such failure and Borrowers shall have failed to correct or cure such failure within 15 days thereafter.

Without limiting the generality of the foregoing, the Borrowers will at all times keep all tangible Collateral insured against risks of fire (including so-called extended coverage), theft, collision (for Collateral consisting of motor vehicles) and such other risks and in such amounts as the Lender may reasonably request, with any loss payable to the Lender to the extent of its interest, and all policies of such insurance shall contain a lender’s loss payable endorsement for the benefit of the Lender. All policies of liability insurance required hereunder shall name the Lender as an additional insured.

     (b) Unless the Borrowers provide the Lender with evidence of the insurance coverage required by this Agreement, the Lender may purchase insurance at the Borrowers’ expense, to protect the Lender’s interests in the Collateral.

The Borrowers may later cancel any insurance purchased by the Lender, but only

after providing the Lender with evidence that the Borrowers have obtained insurance as required by this Agreement. If the Lender purchases insurance for the Collateral, the Borrowers will be responsible for the costs of that insurance, including interest and any other charges that may be imposed in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance may be added to the Loans. The costs of the insurance may be more than the cost of insurance that the Borrowers may be able to obtain on its own.

     Section 6.7 Preservation of Corporate Existence. The Borrowers will preserve and maintain their corporate existence and all of their rights, privileges and franchises necessary or desirable in the normal conduct of their businesses and shall conduct their businesses in an orderly, efficient and regular manner.

To facilitate the performance or observance by the Lender of such covenants of the Borrowers, the Borrowers hereby irrevocably appoint the Lender, or the delegate of the Lender, acting alone, as the attorney in fact of the Borrowers (which appointment is coupled with an interest) with the right following an Event of Default (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file in the name and on behalf of the Borrowers any and all instruments, documents, assignments, security agreements, financing statements, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by the applicable Borrower under this Section 6.10.

In addition, the Borrowers will notify Lender within 10 days of any default under any license agreement through which the Borrower acquired the right to use the trademarks, franchises, trade names, copyrights or patents of a third party.

     Section 6.13 Authorization to File Financing Statements. Borrowers hereby irrevocably authorize Lender at any time and from time to time to file in any filing office in any UCC jurisdiction any initial financing statements and amendments thereto that (a) indicate the Collateral (i) as all assets of a Borrower or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC of such jurisdiction, or (ii) as being of an equal or lesser scope or with greater detail, and (b) provide any other information required by part 5 of Article 9 of the UCC of such jurisdiction, for the sufficiency or filing office acceptance of any financing statement or amendment, including (i) whether a Borrower is an organization, the type of organization and any organizational identification number issued to such Borrower and, (ii) in the case of a financing statement filed as a fixture filing or indicating Collateral as as-extracted collateral or timber to be cut, a sufficient description of real property to which the Collateral relates.

     (e) THE LENDER MAY EXERCISE AND ENFORCE ANY AND ALL RIGHTS AND REMEDIES AVAILABLE UPON DEFAULT TO A SECURED PARTY UNDER THE UCC, INCLUDING, WITHOUT LIMITATION, THE RIGHT TO TAKE POSSESSION OF ANY OR ALL OF THE COLLATERAL, OR ANY EVIDENCE THEREOF, PROCEEDING WITHOUT JUDICIAL PROCESS OR BY JUDICIAL PROCESS (WITHOUT A PRIOR HEARING OR NOTICE THEREOF, WHICH THE BORROWERS HEREBY EXPRESSLY WAIVE) AND THE RIGHT TO SELL, LEASE OR OTHERWISE DISPOSE OF ANY OR ALL OF THE COLLATERAL, AND, IN CONNECTION THEREWITH, THE BORROWERS WILL ON DEMAND ASSEMBLE THE COLLATERAL AND MAKE IT AVAILABLE TO THE LENDER AT A PLACE TO BE DESIGNATED BY THE LENDER WHICH IS REASONABLY CONVENIENT TO BOTH PARTIES;

If notice to the Borrowers of any intended disposition of Collateral or any other intended action is required by law in a particular instance, such notice shall be deemed commercially reasonable if given (in the manner specified in Section 9.3) at least ten calendar days prior to the date of intended disposition or other action.

     Section 8.4 Standards for Exercising Rights and Remedies. To the extent that applicable law imposes duties on the Lender to exercise remedies in a commercially reasonable manner, the Borrowers acknowledge and agree that it is not commercially unreasonable for the Lender (a) to fail to incur expenses reasonably deemed significant by the Lender to prepare Collateral for disposition or otherwise to fail to complete raw material or work in process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents

for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of collateral to be collected or disposed of, (c) to fail to exercise collection remedies against Account debtors or other persons obligated on Collateral or to fail to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against Account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as any Borrower, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the collateral is of a specialized nature, (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure the Lender against risks of loss, collection or disposition of Collateral or to provide to the Lender a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by the Lender, to obtain the services of brokers, investment bankers, consultants and other professionals to assist the Lender in the collection or disposition of any of the Collateral. The Borrowers acknowledge that the purpose of this Section 8.4 is to provide non-exhaustive indications of what actions or omissions by the Lender would fulfill the Lender’s duties under the UCC in the Lender’s exercise of remedies against the Collateral and that other actions or omissions by the Lender shall not be deemed to fail to fulfill such duties solely on account of not being indicated in this Section 8.4. Without limitation upon the foregoing, nothing contained in this Section 8.4 shall be construed to grant any rights to the Borrowers or to impose any duties on the Lender that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 8.4.

ARTICLE IX

Miscellaneous

     Section 9.1 No Waiver; Cumulative Remedies. No failure or delay on the part of the Lender in exercising any right, power or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy under the Loan Documents. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law.

     Section 9.2 Amendments, Etc. No amendment, modification, termination or waiver of any provision of any Loan Document or consent to any departure by the Borrowers therefrom or any release of a Security Interest shall be effective unless the same shall be in writing and signed by the Lender, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No notice to or demand on the Borrowers in any case shall entitle the Borrowers to any other or further notice or demand in similar or other circumstances.

     Section 9.4 Further Documents. The Borrowers will from time to time execute and deliver or endorse any and all instruments, documents, conveyances, assignments, security agreements, financing statements and other agreements and writings that the Lender may reasonably request in order to secure, protect, perfect or enforce the Security Interests or the rights of the Lender under this Agreement (but any failure to request or assure that the Borrowers execute, deliver or endorse any such item shall not affect or impair the validity, sufficiency or enforceability of this Agreement and the Security Interests, regardless of whether any such item was or was not executed, delivered or endorsed in a similar context or on a prior occasion).

     Section 9.5 Collateral. This Agreement does not contemplate a sale of accounts, contract rights or chattel paper, and, as provided by law, the Borrowers are entitled to any surplus and shall remain liable for any deficiency. The Lender’s duty of care with respect to Collateral in its possession (as imposed by law) shall be deemed fulfilled if it exercises reasonable care in physically keeping such Collateral, or in the case of Collateral in the custody or possession of a bailee or other third person, exercises reasonable care in the selection of the bailee or other third person, and the Lender need not otherwise preserve, protect, insure or care for any Collateral. The Lender shall not be obligated to preserve any rights the Borrowers may have against prior parties, to realize on the Collateral at all or in any particular manner or order or to apply any cash proceeds of the Collateral in any particular order of application.

     Section 9.6 Costs and Expenses. The Borrowers agree to pay on demand all reasonable costs and expenses, including (without limitation) attorneys’ fees, incurred by the Lender in connection with the Obligations, this Agreement, the Loan Documents, any Letters of Credit and any other document or agreement related hereto or thereto, and the transactions contemplated hereby, including without limitation all such costs, expenses and fees incurred in connection with the negotiation, preparation, execution, amendment, administration, performance, collection and enforcement of the Obligations and all such documents and agreements and the creation, perfection, protection, satisfaction, foreclosure or enforcement of the Security Interests.

     Section 9.7 Indemnity. In addition to the payment of expenses pursuant to Section 9.7 hereof and the environmental indemnity pursuant to Section 6.3 hereof, the Borrowers agree to indemnify, defend and hold harmless the Lender, and any of its participants, parent corporations, subsidiary corporations, affiliated corporations, successor corporations, and all present and future officers, directors, employees and agents of the foregoing (the “Indemnitees”), from and against (i) any and all transfer taxes, documentary taxes, assessments or charges made by any governmental authority by reason of the execution and delivery of this Agreement and the other Loan Documents or the making of the Advances or issuance of any Letter of Credit, and (ii) any and all liabilities, losses, damages, penalties, judgments, suits, claims, costs and expenses of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of counsel) in connection with any investigative, administrative or judicial proceedings, whether or not such Indemnitee shall be designated a party thereto, which may be imposed on, incurred by or asserted against such Indemnitee, in any manner relating to or arising out of or in connection with the making of the Advances, the issuance of any Letter of Credit, this Agreement and all other Loan Documents or the use or intended use of the proceeds of the Advances or any Letter of Credit or arising out of noncompliance by any Person with any Environmental Law (the “Indemnified Liabilities”), UNLESS A COURT DETERMINES THAT THE LENDER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT CAUSED SUCH LOSS, LIABILITY OR EXPENSE IN WHOLE OR IN PART. If any investigative, judicial or administrative proceeding arising from any of the foregoing is brought against any Indemnitee, upon request of such Indemnitee, any Borrower, or counsel designated by any Borrower and satisfactory to the Indemnitee, will resist and defend such action, suit or proceeding to the extent and in the manner directed by the Indemnitee, at the Borrowers’ sole cost and expense. Each Indemnitee will use its best efforts to cooperate in the defense of any such action, suit or proceeding. If the foregoing undertaking to indemnify, defend and hold harmless may be held to be unenforceable because it violates any law or public policy,

the Borrowers shall nevertheless make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. The obligation of the Borrowers under this Section 9.7 shall survive the termination of this Agreement and the discharge of the Borrowers’ other Obligations.

     Section 9.8 Execution in Counterparts. This Agreement and other Loan Documents may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same instrument. Delivery of an executed counterpart of this Agreement by telefacsimile shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement.

     Section 9.9 Binding Effect; Assignment; Complete Agreement. The Loan Documents shall be binding upon and inure to the benefit of the Borrowers and the Lender and their respective successors and assigns, except that the Borrowers shall not have the right to assign their rights thereunder or any interest therein without the prior written consent of the Lender. The Lender shall have the right at any time to assign its rights under, or grant participations in, this Agreement or the Loan Documents or the loans made pursuant thereto without notice to or consent of the Borrowers. This Agreement, together with the Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and supersedes all prior agreements, written or oral, on the subject matter hereof.

     Section 9.10 Governing Law; Jurisdiction, Venue. The Loan Documents shall be governed by and construed in accordance with the internal substantive laws (other than conflicts-of-law principles) of the State of Missouri, regardless of the place of execution of this Agreement by any party hereto. Each party consents to the personal jurisdiction of the state and federal courts located in the State of Missouri in connection with any controversy related to this Agreement, waives any argument that venue in any such forum is not convenient and agrees that any litigation initiated by any of them in connection with this Agreement shall be venued in either the Circuit Court of St. Louis County, Missouri, or the United States District Court, Eastern District of Missouri.

     Section 9.11 Waiver of Jury Trial. THE BORROWERS HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY (WHICH THE LENDER ALSO WAIVES) IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND, REGARDLESS OF THE LEGAL THEORY UPON WHICH IT IS BASED ARISING OUT OF OR OTHERWISE RELATING TO THIS AGREEMENT, THE OBLIGATIONS, ANY OF THE LOAN DOCUMENTS OR THE LENDER’S CONDUCT IN RESPECT OF ANY OF THE FOREGOING. TO EFFECTUATE THE FOREGOING, THE LENDER IS HEREBY GRANTED AN IRREVOCABLE POWER OF ATTORNEY TO FILE, AS ATTORNEY-IN-FACT FOR THE BORROWERS, A COPY OF THIS AGREEMENT IN ANY COURT PURSUANT TO MO.REV.STAT. § 510.190 AND RULE 69.01, V.A.M.R. AND/OR ANY OTHER APPLICABLE LAW, AND THE COPY OF THIS AGREEMENT SO FILED SHALL CONCLUSIVELY BE DEEMED TO CONSTITUTE THE

BORROWERS’ WAIVER OF TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF OR OTHERWISE RELATING TO THIS AGREEMENT, THE OBLIGATIONS, ANY OF THE LOAN DOCUMENTS OR THE LENDER’S CONDUCT IN RESPECT OF ANY OF THE FOREGOING. IN NO EVENT SHALL LENDER BE LIABLE FOR LOST PROFITS OR OTHER SPECIAL OR CONSEQUENTIAL DAMAGES. REGARDLESS OF THE LEGAL THEORY UPON WHICH IT IS BASED, THE OBLIGATION OF THE BORROWERS UNDER THIS SECTION 9.12 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT AND THE DISCHARGE OF BORROWERS’ OTHER OBLIGATIONS.

     Section 9.12 Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof.

     Section 9.14 Consent to Publicity. With prior consent of Borrowers, Lender may issue and disseminate to the public information describing the credit accommodations entered into pursuant to this Agreement, including the name, logo and location of the Borrowers, the amounts of loans available hereunder and a general description of Borrowers’ business.

UNLESS YOU PROVIDE EVIDENCE OF THE INSURANCE COVERAGE REQUIRED BY YOUR AGREEMENT WITH US, WE MAY PURCHASE INSURANCE AT YOUR EXPENSE TO PROTECT OUR INTERESTS IN YOUR COLLATERAL. THIS INSURANCE MAY, BUT NEED NOT, PROTECT YOUR INTERESTS. THE COVERAGE THAT WE PURCHASE MAY NOT PAY ANY CLAIM THAT YOU MAKE OR ANY CLAIM THAT IS MADE AGAINST YOU IN CONNECTION WITH THE COLLATERAL. YOU MAY LATER CANCEL ANY INSURANCE PURCHASED BY US, BUT ONLY AFTER PROVIDING EVIDENCE THAT YOU HAVE OBTAINED INSURANCE AS REQUIRED BY OUR AGREEMENT. IF WE PURCHASE INSURANCE FOR THE COLLATERAL, YOU WILL BE RESPONSIBLE FOR THE COSTS OF THAT INSURANCE, INCLUDING THE INSURANCE PREMIUM, INTEREST AND ANY OTHER CHARGES WE MAY IMPOSE IN CONNECTION WITH THE PLACEMENT OF THE INSURANCE, UNTIL THE EFFECTIVE DATE OF THE CANCELLATION OR EXPIRATION OF THE INSURANCE. THE COSTS OF THE INSURANCE MAY BE ADDED TO YOUR TOTAL OUTSTANDING BALANCE OR OBLIGATION. THE COSTS OF THE INSURANCE MAY BE MORE THAN THE COST OF INSURANCE YOU MAY BE ABLE TO OBTAIN ON YOUR OWN.

     Section 9.16 Statutory Notice Regarding Oral Agreements. The following notice is given pursuant to Section 432.045 and Section 432.047 of the Missouri Revised Statutes; nothing contained in such notice may be deemed to limit or modify the terms of the Loan Documents:

TO PROTECT YOU (BORROWERS) AND US (LENDER) FROM MISUNDERSTANDING OR DISAPPOINTMENT, ANY AGREEMENTS WE REACH COVERING SUCH MATTERS ARE CONTAINED IN THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, WHICH ARE THE COMPLETE AND EXCLUSIVE STATEMENTS OF THE AGREEMENT BETWEEN US, EXCEPT AS WE MAY LATER AGREE IN WRITING TO MODIFY IT.

     Section 9.17 Reasonableness. When in this Agreement action is stated to be taken or not taken “reasonably” by Lender or is otherwise based upon the reasonableness of Lender, Lender will be deemed to meet such requirements unless Borrowers meet the burden of proof by clear and convincing evidence that the action or inaction of Lender shall have been taken or omitted arbitrarily or capriciously. Lender acknowledges that the foregoing does not affect Lender’s obligation to act reasonably to the extent required under Article 9, Part 6 of the UCC.

    2. Collateral Assignment of Patents, Trade Names, Trademarks and Licenses. To secure the complete and timely satisfaction of all of the “Obligations” and subject to the terms and conditions of this Collateral Assignment:

     8. Severability. The provisions of this Collateral Assignment are severable, and if any clause or provision shall be held unenforceable in whole or in part in any jurisdiction, then such invalidity

Until the Obligations have been satisfied in full and Lender has no further obligation to make any loan to or financial accommodation for the benefit of Assignor, Assignor agrees to undertake all necessary acts to maintain and preserve the Trademarks and the rights under the Trademark Licenses. From and after the occurrence of an Event of Default and notice by Lender to Assignor, Assignor’s exclusive rights to own and use the Trademarks and Trademark Licenses as set forth in this paragraph 8 shall terminate forthwith, to be reinstated only if and when such Event of Default is cured or waived in writing, and Lender shall have, in addition to all other rights and remedies given it by this Collateral Assignment, those allowed by law and the rights and remedies of a secured party under the Uniform Commercial Code as enacted in the State of Missouri.

     6. Reassignment to Assignor. Upon satisfaction in full of the Obligations (provided that Lender has no further obligation to make any loan to or financial accommodation for the benefit of Assignor), Lender’s security interest in the Patents, Technical Information, Trademarks and Trademark Licenses shall terminate.

     7. Lender’s Right to ▇▇▇. At any time after the occurrence and during the continuance of an “Event of Default,” Lender shall have the right, but shall in no way be obligated, to bring suit in its own name to enforce the Patents, Trademarks, and Trademark Licenses and, if Lender shall commence any such suit, Assignor shall, at the request of Lender, do any and all lawful acts and execute any and all proper documents reasonably required by Lender in aid of such enforcement and Assignor shall promptly, upon demand, reimburse and indemnify Lender for all costs and expenses incurred by Lender in the exercise of its rights under this Paragraph 7.

     8. Severability. The provisions of this Collateral Assignment are severable, and if any clause or provision shall be held unenforceable in whole or in part in any jurisdiction, then such invalidity

or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Collateral Assignment in any jurisdiction.

     9. Cumulative Remedies; Effect on Credit Agreement. All of Lender’s rights and remedies with respect to the Patents, Patent Licenses, Trademarks and Trademark Licenses, whether established hereby or by the Credit Agreement, or by any other agreements or by law shall be cumulative.

     10. Binding Effect; Benefits. This Collateral Assignment shall be binding upon each party and its respective successors and assigns, and shall inure to the benefit of both parties and their successors and assigns. This Collateral Assignment cannot be altered, amended or modified in any way, except as specifically provided in paragraph 4 hereof or by a writing signed by the parties hereto.

     11. Governing Law. This Collateral Assignment shall be governed by and construed in accordance with the internal substantive laws of the State of Missouri.

     12. Conflict of Terms.
