limitation, any sums advanced by Secured Party for taxes, assessments, insurance and other charges and expenses as hereinafter provided all obligations and liabilities of Debtor under interest rate swap agreements, interest rate cap agreements and

 3. Representations and Warranties of Debtor. Debtor represents and warrants and, so long as any Indebtedness remains unpaid, shall be deemed
continuously to represent and warrant that: (a) Debtor (OCC with respect to that portion of the Collateral owned by it and SMP with respect to that portion of the Collateral owned by it, and which together constitute all of the Collateral) is

 4. Covenants of Debtor. So long as any Indebtedness remains unpaid, Debtor (a) will defend the Collateral against the claims and demands of
all other parties, including any Account Debtor, will keep the Collateral free from all security interests or other encumbrances other than Permitted Encumbrances, and will not sell, transfer, lease, or otherwise dispose of any Collateral or any
interest without the prior written consent of Secured Party, except that, until the occurrence of an Event of Default as specified in paragraph 10 hereof, Debtor may sell, transfer, lease, assign, deliver or otherwise dispose of any Collateral in
the ordinary course of business; (b) will notify Secured Party promptly in writing of any change in Debtor’s addresses, specified on Schedule I hereto or in Debtor’s name, identity or structure; (c) will notify Secured

proceedings diligently conducted and (ii) Debtor maintains adequate reserves for any such tax, assessment or other charge in accordance with GAAP; and (j) will insure the Collateral against risks, in coverage, form and amount, and by

 5. Verification of Collateral. Secured Party shall have the
right to verify all or any Collateral in any manner and through any medium Secured Party may reasonably consider appropriate, and Debtor agrees to furnish all assistance and information and perform any acts which Secured Party may reasonably require
in connection therewith. 
 6. Notification and Payments. After the occurrence of an Event of Default, Secured Party may notify all or
any Account Debtors of the Security Interest and may also direct such Account Debtors to make all payments on Collateral to Secured Party. After the occurrence of an Event of Default, all payments on and from Collateral received by Secured Party
directly or from Debtor shall be applied to the Indebtedness in such order and manner and at such time as Secured Party shall, in its sole discretion, determine. After the occurrence of an Event of Default, Secured Party may notify any or all
Account Debtors, and other parties obligated to pay the Collateral, of the Security Interest granted hereby and may also direct any and all such parties to make all payments of the Collateral to Secured Party, and Debtor shall join in such
direction, if requested by Secured Party, and Secured Party may demand of Debtor in writing, before or after notification to Account Debtors and without waiving in any manner the Security Interest, that any payments on and from the Collateral
received by Debtor: (i) shall be held by Debtor in trust for Secured Party in the same medium in which received; (ii) shall not be commingled with any assets of Debtor; and (iii) shall be delivered to Secured Party in the form
received, properly indorsed to permit collection, not later than the third Business Day following the day of their receipt; and Debtor shall comply with such demand. Debtor shall also promptly notify Secured Party of the return to or repossession by
Debtor of Goods underlying any Collateral, and Debtor shall hold the same in trust for Secured Party and shall dispose of the same as Secured Party directs. 
 7. Registered Holder of Collateral. After the occurrence of an Event of Default, if any Collateral consists of investment securities, Debtor authorizes Secured Party to transfer the same or any part thereof
into its own name or that of its nominee so that Secured Party or its nominee may appear of record as the sole owner thereof. 
 8. Income
from and Interest on Collateral Consisting of Instruments. 
 (a) Until the occurrence of an Event of Default, Debtor
reserves the right to receive all income from or interest on the Collateral consisting of Instruments or Investment Property, and if Secured Party receives any such income or interest prior to such Event of Default, Secured Party shall pay the same
promptly to Debtor. 
  

 3 

 (b) After the occurrence of an Event of Default, Debtor will not demand or receive any
income from or interest on such Collateral, and if Debtor receives any such income or interest without any demand by it, the same shall be held by Debtor in trust for Secured Party in the same medium in which received, shall not be commingled with
any assets of Debtor and shall be delivered to Secured Party in the form received, properly indorsed to permit collection, not later than the third Business Day following the day of its receipt. Secured Party may apply the net cash receipts from
such income or interest to payment of any of the Indebtedness; provided, that Secured Party shall account for and pay over to Debtor any such income or interest remaining after payment in full of the Indebtedness. 
 9. Increases, Profits, Payments or Distributions. 
 (a) After the occurrence of an Event of Default, Debtor authorizes Secured Party: (i) to receive any increase in or profits on the Collateral (including, without limitation, any Investment Property issued as a
result of any stock split or dividend, any capital distributions and the like), and to hold the same as part of the Collateral; and (ii) to receive any payment or distribution on the Collateral upon redemption by, or dissolution and liquidation
of, the issuer or any Investment Property; to surrender such Collateral or any part thereof in exchange therefor; and to hold the net cash receipts from any such payment or distribution as part of the Collateral. 
 (b) After the occurrence of an Event of Default, if Debtor receives any such increase, profits, payments or distributions, Debtor will
receive and deliver same promptly to Secured Party on the same terms and conditions set forth in paragraph 8(b) hereof respecting income or interest, to be held by Secured Party as part of the Collateral. 
 10. Event of Default. 
 (a) An Event of Default hereunder shall be the occurrence of an “Event of Default” under and as defined in the Credit Agreement or under any of the other Loan Documents. 
 (b) Upon the happening of any Event of Default, Secured Party’s rights and remedies with respect to the Collateral shall be those of
a Secured Party under the Uniform Commercial Code in effect from time to time in the Commonwealth of Virginia (the “UCC”), and under any other applicable law in addition to those rights granted herein and in any other agreement now or
hereafter in effect between Debtor and Secured Party; 
 (c) Debtor agrees to pay all costs and expenses incurred by Secured
Party in enforcing this Agreement, in preserving, processing, selling, collecting upon or in realizing upon any Collateral and in enforcing and collecting any Indebtedness, including, without limitation, if Secured Party retains counsel for any such
purpose, actual attorney’s fees and expenses. 
  

 4 

 11. Notices. All notices, requests, demands or other communications to or upon Debtor or Secured
Party shall be made in accordance with Section 10.1 of the Credit Agreement. 
 12. Miscellaneous. 
 (a) Debtor hereby authorizes Secured Party, at Debtor’s expense, to file such financing statement or statements, or other documents
relating to the Collateral without Debtor’s signature thereon as Secured Party at its option may deem appropriate, and appoints Secured Party as Debtor’s attorney-in-fact (without requiring Secured Party) to execute any such financing
statement or other documents in Debtor’s name and to perform all other acts which Secured Party deems appropriate to perfect and continue the Security Interest and to protect and preserve the Collateral. Such financing statements may describe
the Collateral in the same manner as described herein or may contain a description of collateral that describes such property in any other manner as Secured Party may determine, in its sole discretion, is necessary, advisable or prudent to ensure
the perfection or priority of the Security Interest in the Collateral granted to Secured Party hereunder, including, describing such property as “all assets whether now owned or hereafter acquired” or “all personal property whether
now owned or hereafter acquired” (regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC). Debtor hereby ratifies and authorizes the filing by Secured Party in any relevant
jurisdiction of any initial financing statements or amendments thereto relating to the Collateral if filed prior to the date hereof; 
 (b) (i) As further security for payment of the Indebtedness, Debtor hereby grants to Secured Party a security interest in and lien on any and all property of Debtor which is or may hereafter be in Secured Party’s possession in any
capacity which lien shall be subject and subordinate to prior existing liens, if any, and with respect to all of such property, Secured Party shall have the same rights hereunder as it has with respect to the Collateral; 
 (ii) Without limiting any other right of Secured Party, whenever Secured Party has the right to declare any Indebtedness to be immediately
due and payable (whether or not it has so declared), Secured Party at its sole election may set off against the Indebtedness any and all monies then owed to Debtor by Secured Party in any capacity, whether or not due, and Secured Party shall be
deemed to have exercised such right of set-off immediately at the time of such election even though any charge therefor is made or entered on Secured Party’s records subsequent thereto; 
 (c) Upon Debtor’s failure to perform any of its duties hereunder, Secured Party may, but shall not be obligated to, perform any and
all such duties, and Debtor shall pay an amount equal to the expense thereof to Secured Party forthwith upon written demand by Secured Party; 
  

 5 

 (d) Secured Party may demand, collect and sue on the Collateral (in either Debtor’s
or Secured Party’s name at the latter’s option) with the right to enforce, compromise, settle or discharge the Collateral, and may endorse Debtor’s name on any and all checks, commercial paper, and any other Instruments pertaining to
or constituting the Collateral; 
 (e) No course of dealing and no delay or omission by Secured Party in exercising any right
or remedy hereunder with respect to any Indebtedness shall operate as a waiver thereof or of any other right or remedy, and no single or partial exercise thereof shall preclude any other or further exercise thereof or the exercise of any other right
or remedy. Secured Party may remedy any Default or Event of Default by Debtor hereunder or with respect to any Indebtedness in any reasonable manner without waiving the Default or Event of Default remedied and without waiving any other prior or
subsequent Default or Event of Default by Debtor. All rights and remedies of Secured Party hereunder are cumulative and may be exercised in any order and in any combination with Secured Party’s rights under the UCC or otherwise; 
 (f) Secured Party shall have no obligation to take, and Debtor shall have the sole responsibility for taking, any and all steps to
preserve rights against any and all prior parties to any Instrument, Investment Property or Chattel Paper, or Proceeds thereof, and whether or not in Secured Party’s possession. Debtor waives protest of any Instrument constituting Collateral at
any time held by Secured Party on which Debtor is in any way liable and waives notices of any other action taken by Secured Party; 
 (g) The rights and benefits of Secured Party hereunder shall, if Secured Party so agrees, inure to any party acquiring any interest in the Indebtedness or any part thereof; 
 (h) No modification, rescission, waiver, release or amendment of any provision of this Agreement shall be made except by a written
agreement subscribed by Debtor and by a duly authorized officer of Secured Party; 
 (i) All capitalized terms used herein
without definition shall have the meanings ascribed to such terms under the Credit Agreement, dated as of May 30, 2008, between Debtor and Secured Party (including all schedules, subschedules, annexes and exhibits thereto), as the same may be
amended, restated, supplemented, replaced, or otherwise modified from time to time (the “Credit Agreement”), or if not defined therein, under the UCC; 
 (j) Upon receipt of an affidavit of an officer of Secured Party as to the loss, theft, destruction or mutilation of this Agreement or any
other security document which is not of public record and, in the case of any such loss, theft, destruction or mutilation, upon cancellation of any promissory note or other security document, Debtor will issue, in lieu thereof, a replacement note or
other security document in the same principal amount thereof and otherwise of like tenor. 
  

 6 

 (k) This Agreement shall remain in full force and effect until all of the Indebtedness
contracted for or any extensions or renewals thereof (whether made before or after receipt of such notice) together with interest accruing thereon after such notice, shall be irrevocably paid in full. 
 13. General Waivers. Debtor hereby waive(s) presentment, notice of dishonor and protest of all instruments included in or evidencing the
Indebtedness or the Collateral and any and all other notices and demands whatsoever. The undersigned waives all demands, notices and protests of every kind which are not expressly required under this Agreement which are permitted by law to be
waived, and which would, if not waived, impair Secured Party’s enforcement of this Agreement or release any collateral from Secured Party’s security interest hereunder. By way of example, but not in limitation of Secured Party’s
rights under this Agreement, Secured Party does not have to give any undersigned notice of any of the following: 
 (a) notice
of acceptance of this Agreement; 
 (b) notice of loans made, credit extended, Collateral received or delivered; 

(c) any Event of Default; 
 (d) except as otherwise provided herein, enforcement of this Agreement against the Collateral; or 
 (e) any other action taken in reliance on this Agreement. 
 Debtor waives all rules of suretyship law and any other law whatsoever which is legally
permitted to be waived and which would, if not waived, impair Secured Party’s enforcement of its security interests. 
 14. Waiver of
Jury Trial. DEBTOR AND SECURED PARTY HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE CREDIT AGREEMENT AND OTHER LOAN DOCUMENTS. DEBTOR AND SECURED PARTY
ACKNOWLEDGE THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS RELIED ON THE WAIVER IN ENTERING INTO THIS AGREEMENT, THE CREDIT AGREEMENT AND OTHER LOAN DOCUMENTS AND THAT EACH WILL CONTINUE TO RELY ON THE
WAIVER IN THEIR RELATED FUTURE DEALINGS. DEBTOR AND SECURED PARTY WARRANT AND REPRESENT THAT EACH HAS HAD THE OPPORTUNITY TO REVIEW THIS JURY WAIVER WITH LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS.

  

 7 

 15. Severability. If any provision of this Agreement shall be held invalid under any applicable
laws, such invalidity shall not affect any other provision of this Agreement that can be given effect without the invalid provision, and, to this end, the provisions hereof are severable. 
 16. Governing Law. This Agreement and the transactions evidenced hereby shall be construed under the internal laws of the Commonwealth of Virginia
without regard to principles of conflict of law. Debtor agrees that any suit for the enforcement of this Agreement, the Credit Agreement or any of the other Loan Documents may be brought in the courts of Roanoke City, Virginia or any Federal Court
for the Western District of Virginia sitting therein and consents to the nonexclusive jurisdiction of such court and service of process in any such suit being made upon Debtor by mail at the address of Debtor set forth in Section 10.1 of the
Credit Agreement. Debtor hereby waives any objection that it may now or hereafter have to the venue of any such suit or any such court or that such suit is brought in an inconvenient forum. 
 17. Execution by Secured Party. This Agreement shall take effect immediately upon execution by Debtor and the execution hereof by Secured Party
shall not be required as a condition to the effectiveness of this Agreement. The provision for execution by Secured Party is solely for the purpose of filing this Agreement to the extent required or permitted by law.

 FOR VALUE RECEIVED, OPTICAL CABLE CORPORATION, a Virginia corporation and SUPERIOR MODULAR
PRODUCTS INCORPORATED, a Delaware corporation (each individually with respect to itself, jointly and severally, and collectively, the “Borrower”), hereby promises to pay to the order of VALLEY BANK, a Virginia banking corporation, its
affiliates and their successors and assigns (the “Bank”) at its Head Office, in lawful money of the United States and in immediately available funds, the principal amount of up to SIX MILLION AND NO/100 DOLLARS ($6,000,000.00), or such sum
as may be advanced and outstanding from time to time, and to pay interest from the date of this note (herein referred to as the “Note”) on the unpaid principal amount outstanding under this Note, in like money, at the time, in amounts, and
at the rate per annum as provided in Section 3.1(a) of the credit agreement of even date herewith between the Borrower and the Bank, as modified, replaced or restated (the “Credit Agreement”). 
 This Note is referred to as the Revolving Loan Note in the Credit Agreement. The Credit Agreement contains, among other things, provisions for
acceleration of the maturity of this Note upon the happening of certain stated events and for prepayments on account of the principal of this Note prior to maturity of this Note upon the terms and conditions specified in the Credit Agreement.

 Capitalized terms contained in this Note which are not otherwise defined herein shall have the meaning ascribed to them in the Credit
Agreement. 
 This Note is governed by and subject to additional terms and conditions of the Credit Agreement and is secured by the
Collateral described in the Credit Agreement and the other Loan Documents, reference to which is hereby made for a description of the Collateral and the rights of the Borrower and the Bank with respect to the Collateral and the remedies of the Bank
pertaining thereto. In the event of a conflict between any term or condition contained in this Note and the Credit Agreement, such term or condition of the Credit Agreement shall control. The proceeds of any Collateral may be applied against the
liabilities of the Borrower to the Bank as provided in the Loan Documents. 
 If an Event of Default occurs, the Bank shall have the option
to exercise all of the rights and remedies provided in the Credit Agreement. To the extent permitted by law, upon default, the Bank reserves the right, in addition to all other remedies permitted by law or in the Credit Agreement, to set off the
amount due under this Note or due under any other obligation to the Bank against any and all accounts, whether checking or savings or otherwise, credits, money, stocks, bonds or other security or property of any nature whatsoever on deposit with,
held by, owned by, or in the possession of, the Bank, or any of its affiliates to the credit of or for the account of the Borrower or any other party to the Credit Agreement, without notice to or consent by the Borrower or any such party. The
remedies provided in this Note, the Credit Agreement, and any other agreement between the Bank and the Borrower are cumulative and are not exclusive of any remedies provided by law. 
 If any portion of a payment is at least ten days past due, the Borrower promises to pay a late charge of five percent of the 

 
amount which is past due. In addition, to the extent not prohibited by applicable law, the undersigned promises to pay the following: (1) all expenses,
including, without limitation, any and all court or collection costs, and reasonable attorney’s fees, whether suit be brought or not, incurred in collecting this Note or in otherwise protecting the Bank’s interests; (2) all costs
incurred in evaluating, preserving or disposing of any Collateral granted as security for the payment of this Note, including the cost of any audits, appraisals, appraisal updates, reappraisals or environmental inspections which the Bank from time
to time in its sole discretion may deem necessary; (3) any premiums for property insurance purchased on behalf of the Borrower or on behalf of the owner or owners of the Collateral pursuant to any Loan Document relating to the Collateral;
(4) any expenses or costs incurred in defending any claim arising out of the execution of this Note or the obligation which it evidences, or otherwise involving the employment by the Bank of attorneys with respect to this Note and the
obligations it evidences; and (5) any other charges permitted by applicable law. The Borrower shall pay such authorized charges on demand or, at the Bank’s option, such charges may be added to the unpaid balance of the Note and shall
accrue interest at the stated rate of interest. 
 The Borrower waives presentment, demand, protest, notice of protest and notice of dishonor
and waives all exemptions as to the obligations evidenced by this Note. The Borrower waives any rights to require the Bank to proceed against any other party or person or any Collateral before proceeding against the Borrower, or any other party. The
Bank may, without notice, without affecting the liability of the Borrower hereunder or under the Credit Agreement, and at any time or times, grant extensions of the time for payment or other indulgences to any party or permit the renewal or
modification of this Note, or permit the substitution, exchange or release of any Collateral for this Note and may add or release any party primarily or secondarily liable. The Bank may apply all monies made available to it from any part of the
proceeds of the disposition of any Collateral or by exercise of the right of setoff either to the obligations under this Note or to any other obligations of the Borrower to the Bank, as provided in the Credit Agreement. The undersigned specifically
waives any rights afforded to it by Sections 49-25 and 49-26 of the Code of Virginia of 1950 as amended. 
 TO THE EXTENT LEGALLY PERMISSIBLE, THE
BORROWER WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY LITIGATION RELATING TO TRANSACTIONS UNDER THIS NOTE, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. 
 Any provision of this Note which is prohibited or unenforceable shall be ineffective only to the extent of such prohibition or unenforceability without invalidating the remaining provisions of this Note. No amendment,
termination or waiver of any provision of this Note, nor consent to any departure by the Borrower from any term of this Note, shall in any event be effective unless it is in writing and signed by an authorized employee of the Bank, and then such
waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure or delay on the part of the Bank to exercise any right, power or remedy under this Note shall be construed as a waiver of the
right to exercise the same or any other right at any time. 
 This Note shall apply to and bind the Borrower and its successors and assigns
and shall inure to the benefit of the Bank, its successors and assigns. This Note shall be governed by the internal laws of the Commonwealth of Virginia and applicable federal law. The Borrower acknowledges that the events and occurrences relating
to this Note bear a reasonable relationship to the laws of the Commonwealth of Virginia. The validity, terms, performance and enforcement of this Note shall be governed by applicable federal law and the internal laws of the Commonwealth of Virginia.

 By signing below, the Borrower agrees to the terms of this Note.
