Re: Notes due 2026 

 

Gentlemen:

 

Dynasil Corporation of America, a Delaware
corporation (the "Company"), hereby agrees with Massachusetts Capital Resource Company (the "Purchaser")
as follows:

 

BACKGROUND

 

The Company and the Purchaser
are parties to that certain: (i) Note Purchase Agreement, dated as of July 31, 2012, as amended, (the “Prior Purchase Agreement”)
pursuant to which the Company issued to the Purchaser the Company Note, due November 30, 2021, in the original principal amount
of $3,000,000, which Note has a present outstanding principal balance of $865,216 (the “Prior Note);

 

The Company has requested:
(i) an additional loan of $2,000,000 from the Purchaser, in accordance with the terms and conditions of this Agreement, and (ii)
that the Prior Purchase Agreements be amended, restated and consolidated into one Purchase Agreement with the new loan and that
the Prior Notes and the note presenting the new loan be consolidated into one Note which will be due July 31, 2026. The consolidated
Note will be in the original aggregate principal amount of $2,865,216, which will be issued for $2,000,000 in cash and the exchange
of the Prior Note which has an outstanding principal amount of $865,216.

 

ARTICLE I

 

PURCHASE, SALE AND TERMS OF NOTES 

 

1.01. The Notes. The Company has
authorized the issuance and sale to the Purchaser of the Company's Notes, due 2026, in the original principal amount of $2,865,216.
The Notes shall be substantially in the form set forth in Exhibit 1.01 hereto and are herein referred to individually as
a "Note" and collectively as the "Notes", which terms shall also include any notes delivered in exchange or
replacement therefor.

 

     

     

    

 

1.02. Purchase and Sale of Notes .

 

(a) The Closing. The Company agrees
to issue to the Purchaser, and, subject to and in reliance upon the representations, warranties, terms and conditions of this Agreement,
the Purchaser agrees to purchase, the Notes for an aggregate purchase price of $2,865,216. Such purchase and sale shall take place
at a closing (the “Closing”) to be held at the Law Office of George W. Thibeault, 60 State Street, Suite 700, Boston,
Massachusetts, 02109 on August 6, 2019 at 1:00 P.M. or on such other date and at such time as may be mutually agreed upon. At the
Closing the Company will initially issue one Note, payable to the order of the Purchaser, in the principal amount of $2,865,216,
and Purchaser shall tender a wire transfer to the Company in the amount of $2,000,000, and the exchange of the Prior Note having
an aggregate outstanding principal balance of $865,216, all in payment of the full purchase price for the Notes. In addition, the
Company will deliver to the Purchaser, at the Closing, a check or wire transfer for all accrued and unpaid interest on the Prior
Note, calculated through the Closing

 

(b) Use of Proceeds. The Company
agrees to use the full proceeds from the sale of the Notes solely to assist in a stock buyback and refinancing of existing indebtedness
and for working capital and agrees that full proceeds from the sale of the Notes will be utilized for purposes which increase
or maintain equal opportunity employment in the Commonwealth of Massachusetts.

 

1.03. Payments and Endorsements.
Payments of principal, interest and premium, if any, on the Notes, shall be made directly by check duly mailed or delivered to
the Purchaser at its address referred to in Section 7.03 hereof or, if requested by the Purchaser, by wire transfer to an
account designated by the Purchaser, without any presentment or notation of payment, except that prior to any transfer of any Note,
the holder of record shall endorse on such Note a record of the date to which interest has been paid and all payments made on account
of principal of such Note.

 

1.04. Redemptions.

 

(a) Required Redemptions. Beginning
on and with August 31, 2022, and on the last day of each calendar month thereafter through and including July 31, 2026, the Company
will redeem, without premium, $59,692.00 in principal amount of the Notes, or such lesser amount as may be then outstanding, together
with all accrued and unpaid interest then due on the amount so redeemed. On the stated or accelerated maturity of the Notes, the
Company will pay the principal amount of the Notes then outstanding together with all accrued and unpaid interest then due thereon.
No optional redemption of less than all of the Notes shall affect the obligation of the Company to make the redemptions required
by this subsection.

 

    	 	- 2 -	 

     

    

 

(b) Optional Redemptions With Premium.
The Company may at any time redeem the Notes in whole or in part (in integral multiples of $50,000) together with interest due
on the amount so redeemed through the date of redemption, and a premium equal to the percentage of the principal amount of the
Notes redeemed under this subsection applicable to the period in which such redemption is made, as follows:

 

	Period Ending	 	Premium	 
	August 31, 2020	 	 	2.0	%
	August 31, 2021	 	 	1.0	%
	thereafter	 	 	0	%

 

(c) Notice of Redemptions; Pro rata Redemptions.
Notice of any optional redemptions pursuant to subsection 1.04(b) shall be given to all registered holders of the Notes at least
ten (10) business days prior to the date of such redemption. Each redemption of Notes pursuant to subsections 1.04(a) or (b) shall
be made so that the Notes then held by each holder shall be redeemed in a principal amount which shall bear the same ratio to the
total principal amount of Notes being redeemed as the principal amount of Notes then held by such holder bears to the aggregate
principal amount of the Notes then outstanding.

 

1.05. Payment on Non-Business Days.
Whenever any payment to be made shall be due on a Saturday, Sunday or a public holiday under the laws of the Commonwealth of Massachusetts,
such payment may be made on the next succeeding business day, and such extension of time shall in such case be included in the
computation of payment of interest due.

 

1.06. Registration, etc. The Company
shall maintain at its principal office a register of the Notes and shall record therein the names and addresses of the registered
holders of the Notes, the address to which notices are to be sent and the address to which payments are to be made as designated
by the registered holder if other than the address of the holder, and the particulars of all transfers, exchanges and replacements
of Notes. No transfer of a Note shall be valid unless made on such register for the registered holder or his executors or administrators
or his or their duly appointed attorney, upon surrender therefor for exchange as hereinafter provided, accompanied by an instrument
in writing, in form and execution reasonably satisfactory to the Company. Each Note issued hereunder, whether originally or upon
transfer, exchange or replacement of a Note or Notes, shall be registered on the date of execution thereof by the Company and shall
be dated the date to which interest has been paid on such Notes or Note. The registered holder of a Note shall be that Person in
whose name the Note has been so registered by the Company. A registered holder shall be deemed the owner of a Note for all purposes
of this Agreement and, subject to the provisions hereof, shall be entitled to the principal, premium, if any, and interest evidenced
by such Note free from all equities or rights of setoff or counterclaim between the Company and the transferor of such registered
holder or any previous registered holder of such Note.

 

1.07. Transfer and Exchange of Notes.
The registered holder of any Note or Notes may, prior to maturity or prepayment thereof, surrender such Note or Notes at the principal
office of the Company for transfer or exchange. Within a reasonable time after notice to the Company from a registered holder of
its intention to make such exchange and without expense (other than transfer taxes, if any) to such registered holder, the Company
shall issue in exchange therefor another Note or Note, in such denominations as requested by the registered holder, for the same
aggregate principal amount as the unpaid principal amount of the Note or Notes so surrendered, and having the same maturity and
rate of interest, containing the same provisions and subject to the same terms and conditions as the Note or Notes so surrendered.
Each new Note shall be made payable to such Person or Persons, or registered assigns, as the registered holder of such surrendered
Note or Notes may designate, and such transfer or exchange shall be made in such a manner that no gain or loss of principal or
interest shall result therefrom.

 

    	 	- 3 -	 

     

    

 

1.08. Replacement of Notes. Upon
receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any Note and, if requested in
the case of any such loss, theft or destruction, upon delivery of an indemnity bond or other agreement or security reasonably satisfactory
to the Company, or, in the case of any such mutilation, upon surrender and cancellation of such Note, the Company will issue a
new Note, of like tenor and amount and dated the date to which interest has been paid, in lieu of such lost, stolen, destroyed
or mutilated Note; provided, however, if any Note of which Massachusetts Capital Resource Company, its nominee, or
any of its partners is the registered holder is lost, stolen or destroyed, the affidavit of the President, Treasurer or any Assistant
Treasurer of the registered holder setting forth the circumstances with respect to such loss, theft or destruction shall be accepted
as satisfactory evidence thereof, and no indemnification bond or other security shall be required as a condition to the execution
and delivery by the Company of a new Note in replacement of such lost, stolen or destroyed Note other than the registered holder's
written agreement to indemnify the Company.

 

1.09. Subordination. The Company,
for itself, its successors and assigns, covenants and agrees, and the Purchaser and each successor holder of the Notes by its acceptance
thereof, likewise covenants and agrees, that notwithstanding any other provision of this Agreement or the Notes, the payment of
the principal of and interest on each and all of the Notes shall be subordinated in right of payment, to the extent and in the
manner hereinafter set forth, to the prior payment in full of all Senior Debt (as hereinafter defined) at any time outstanding.
The provisions of this Section 1.09 shall constitute a continuing representation to all Persons who, in reliance upon such
provisions, become the holders of or continue to hold Senior Debt, and such provisions are made for the benefit of the holders
of Senior Debt, and such holders are hereby made obligees hereunder the same as if their names were written herein as such, and
they or any of them may proceed to enforce such provisions against the Company or against the holder of any Note without the necessity
of joining the Company as a party.

 

    	 	- 4 -	 

     

    

 

(a) Payment of Senior Debt. In the
event of any insolvency or bankruptcy proceedings, or any receivership, liquidation, reorganization or other similar proceedings
in connection therewith, relative to the Company or to its property, or, in the event of any proceedings for voluntary liquidation,
dissolution or other winding up of the Company or distribution or marshalling of its assets or any composition with creditors of
the Company, whether or not involving insolvency or bankruptcy, then and in any such event all Senior Debt shall be paid in full
before any payment or distribution of any character, whether in cash, securities or other property, shall be made on account of
the Notes; and any such payment or distribution, except securities which are subordinated and junior in right of payment to the
payment of all Senior Debt then outstanding in terms of substantially the same tenor as this Section 1.09, which would, but
for the provisions hereof, be payable or deliverable in respect of the Notes shall be paid or delivered directly to the holders
of Senior Debt (or their duly authorized representatives), in the proportions in which they hold the same, until all Senior Debt
shall have been paid in full, and every holder of the Notes by becoming a holder thereof shall have designated and appointed the
holder or holders of Senior Debt (and their duly authorized representatives) as his or its agents and attorney-in-fact to demand,
sue for, collect and receive such Senior Debt holder's ratable share of all such payments and distributions and to file any necessary
proof of claim therefor and to take all such other action in the name of the holders of the Notes or otherwise, as such Senior
Debt holders (or their authorized representatives) may determine to be necessary or appropriate for the enforcement of this Section 1.09.
The Purchaser and each successor holder of the Notes by its or his acceptance thereof agrees to execute, at the request of the
Company, a separate agreement with any holder of Senior Debt on the terms set forth in this Section 1.09, and to take all
such other action as such holder or such holder's representative may request in order to enable such holder to enforce all claims
upon or in respect of such holder's ratable share of the Notes.

 

(b) No Payment on Notes Under Certain Conditions.
In the event that any default occurs in the payment of the principal of or interest on any Senior Debt (whether as a result of
the acceleration thereof by the holders of such Senior Debt or otherwise) and during the continuance of such default for a period
up to one hundred twenty (120) days and thereafter if judicial proceedings shall have been instituted with respect to such defaulted
payment, or (if a shorter period) until such payment has been made or such default has been cured or waived in writing by such
holder of Senior Debt then and during the continuance of such event no payment of principal or interest on the Notes shall be made
by the Company or accepted by any holder of the Notes who has received notice from the Company or from a holder of Senior Debt
of such events.

 

(c) Payments Held in Trust. In case
any payment or distribution shall be paid or delivered to any holder of the Notes before all Senior Debt shall have been paid in
full, despite or in violation or contravention of the terms of this subordination, such payment or distribution shall be held in
trust for and paid and delivered ratably to the holders of Senior Debt (or their duly authorized representatives), until all Senior
Debt shall have been paid in full.

 

(d) Subrogation. Subject to the
payment in full of all Senior Debt and until the Notes shall be paid in full, the holders of the Notes shall be subrogated to the
rights of the holders of Senior Debt (to the extent of payments or distributions previously made to such holders of Senior Debt
pursuant to the provisions of subsections (a) and (c) of this Section 1.09) to receive payments or distributions of assets
of the Company applicable to the Senior Debt. No such payments or distributions applicable to the Senior Debt shall, as between
the Company and its creditors, other than the holders of Senior Debt and the holders of the Notes, be deemed to be a payment by
the Company to or on account of the Notes; and for the purposes of such subrogation, no payments or distributions to the holders
of Senior Debt to which the holders of the Notes would be entitled except for the provisions of this Section 1.09 shall, as
between the Company and its creditors, other than the holders of Senior Debt and the holders of the Notes, be deemed to be a payment
by the Company to or on account of the Senior Debt.

 

    	 	- 5 -	 

     

    

 

(e) Scope of Section. The provisions
of this Section 1.09 are intended solely for the purpose of defining the relative rights of the holders of the Notes, on the
one hand, and the holders of the Senior Debt, on the other hand. Nothing contained in this Section 1.09 or elsewhere in this
Agreement or the Notes is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Debt,
and the holders of the Notes, the obligation of the Company, which is unconditional and absolute, to pay to the holders of the
Notes the principal of and interest on the Notes as and when the same shall become due and payable in accordance with the terms
thereof, or to affect the relative rights of the holders of the Notes and creditors of the Company other than the holders of the
Senior Debt, nor shall anything herein or therein prevent the holder of any Note from accepting any payment with respect to such
Note or exercising all remedies otherwise permitted by applicable law upon default under such Note, subject to the rights, if any,
under this Section 1.09 of the holders of Senior Debt in respect of cash, property or securities of the Company received by
the holders of the Notes.

 

(f) Survival of Rights. The right
of any present or future holder of Senior Debt to enforce subordination of the Notes pursuant to the provisions of this Section 1.09
shall not at any time be prejudiced or impaired by any act or failure to act on the part of the Company or any such holder of Senior
Debt, including, without limitation, any forbearance, waiver, consent, compromise, amendment, extension, renewal, or taking or
release of security of or in respect of any Senior Debt or by noncompliance by the Company with the terms of such subordination
regardless of any knowledge thereof such holder may have or otherwise be charged with.

 

(g) Amendment or Waiver. The provisions
of this Section 1.09 may not be amended or waived in any manner which is detrimental to any Senior Debt without the consent
of the holders of all then existing Senior Debt.

 

(h) Senior Debt Defined. The term
"Senior Debt" shall mean (i) all Indebtedness of the Company for money borrowed from banks or other institutional lenders,
including without limitation Middlesex Savings Bank, including any extension or renewals thereof, whether outstanding on the date
hereof or thereafter created or incurred, which is not by its terms subordinate and junior to or on a parity with the Notes and
which is permitted hereby at the time it is created or incurred, and (ii) all guaranties by the Company which are not by their
terms subordinate and junior to or on a parity with the Notes and which are permitted hereby at the time they are made, of Indebtedness
of any Subsidiary if such Indebtedness would have been Senior Debt pursuant to the provisions of clause (i) of this sentence had
it been Indebtedness of the Company. In making any loans which are (or the guaranties of which are) intended to be Senior Debt,
the lenders or purchasers shall be entitled to rely as to the fact that such Indebtedness or guaranty is permitted hereby upon
a certificate by the Company's chief financial officer purporting to show such Indebtedness or guaranty will not result in the
Company's failure to comply with the provisions of Article IV hereof as of the date of the loan or guarantee.

 

(i) Subordination Agreement. For
as long as there shall be any outstanding Liabilities (as such term is defined in that certain Subordination Agreement, dated as
of May 1, 2014, between Middlesex Savings Bank. and the Company, as amended, modified or restated from time to time, the “Subordination
Agreement”) or any obligation of any nature on the part of Middlesex Savings Bank, or its successors or assigns, to extend
credit, or make loans or advances to the Company or any Subsidiary, the terms and conditions of the Subordination Agreement shall
supercede and replace all of the terms and conditions of this Section 1.09, except for clause (h) above and this clause (i).

1.10. Representations by the Purchaser.
The Purchaser represents and warrants that:

 

(a)       
Accredited Investor. Purchaser is an “accredited investor,” as defined in SEC Rule 501(a).

 

(b)       
Notes not Registered. Purchaser acknowledges that the sale of the Notes has not been registered under the U.S. Securities
Act of 1933 (the “Securities Act”) or any state securities law in reliance on Purchaser’s representations herein,
and that no government agency has approved of the offering of the Notes.

 

(c)       Acquisition
for Own Account. Purchaser is acquiring the Notes solely for its own account for investment and not with a view to or any present
intention of selling, offering to sell, or otherwise disposing of or distributing the Notes or any portion thereof.

 

(d)       Availability
of Information. Purchaser understands that the Notes are being sold without any particular prospectus or offering document,
and that no government agency has approved of the adequacy or accuracy of the information provided to Purchaser. Purchaser has
discussed the Company and its plans, technology, operations, financial condition, and prospects with its officers and/or directors.
Purchaser has received satisfactory responses to all its inquiries and all such information as Purchaser deems necessary and appropriate
to enable it to evaluate the risks inherent in making an investment in the Notes.

 

(e)       Investment
Involves Substantial Risk and Illiquidity. Purchaser acknowledges that (i) the Company’s technology and business prospects
are unproven, (ii) the acquisition of the Notes is a highly speculative investment involving substantial risk, (iii) there
is not and may never be any market for the Notes, and (iv) it may be required to hold the Notes until maturity. Purchaser does
not anticipate needing liquidity for the Notes, and it is able, without impairing its financial condition, to suffer a complete
loss of its investment in the Notes.

 

(f)       Restrictions on Transfer.
Purchaser understands that it may not sell, pledge or otherwise transfer any Notes unless the Company registers such Notes under
the Securities Act and applicable state laws or unless an exemption from such registration requirements is available. Purchaser
understands that the Company is under no obligation to register any transfer of the Notes by it unless such Notes are registered
under the Securities Act and applicable state laws or unless an exemption from such registration requirements is available and
that exemptions from registration may not be available or may not permit it to transfer or resell all or any Notes in the amounts
or at the times proposed by Purchaser.

 

    	 	- 7 -	 

     

    

 

1.11. Disclosure of Information by the
Purchaser. The Company understands that the Purchaser is a special purpose limited partnership organized under Chapter 109
of the General Laws of the Commonwealth of Massachusetts and Chapter 816 of the Acts and Resolves of 1977 of the Commonwealth
of Massachusetts (the "Capital Resource Company Act"), and as such, in accordance with such provisions, the Purchaser,
in order to obtain certain benefits for itself and its partners, is required to file certain reports and otherwise disclose information
relating to the business, financial affairs, and future prospects of the Company and its affiliates (as defined in the aforesaid
legislation) with the Clerk of the Senate and the Clerk of the House of Representatives of the General Court of the Commonwealth
of Massachusetts, the Secretary of Manpower Affairs, the Commissioner of Insurance and the Department of Revenue of the Commonwealth
of Massachusetts, and that such reports and other information may constitute "public records" within the purview of Section 7
of Chapter 4 of the General Laws of the Commonwealth of Massachusetts. In addition, information relating to the business,
financial affairs and future prospects of the Company and its affiliates must be disclosed to others in order to obtain independent
confirmation that financing on substantially similar terms to financing provided pursuant to this Agreement was not elsewhere available
to the Company. The Company hereby authorizes the Purchaser to disclose all such information relating to the business, financial
affairs and future prospects of the Company and its affiliates as has been or may in the future be presented to the Purchaser to
all such persons as the Purchaser in good faith deems necessary or appropriate in order to fulfill its obligations under the Capital
Resource Company Act. The Purchaser understands and has been advised that the provisions of SEC Regulation FD requires the public
announcement of previously non-public material information if that information is disclosed to anyone who has not agreed to maintain
the confidentiality of that information, and Purchaser agrees to take no action that would require the Company to make a public
announcement pursuant to the requirements of Regulation FD, except as required by law, in which case Purchaser shall use reasonable
efforts to give the Company written notice of the proposed action a reasonable time in advance of such proposed action; provided,
however, that the Purchaser shall have no liability for failure to give such notice.

ARTICLE III

 

REPRESENTATIONS AND WARRANTIES

 

The Company represents and warrants as follows:

 

3.01. Organization and Standing .
The Company and each Subsidiary is a duly organized and validly existing corporation or limited liability company, as the case
may be, in good standing under the laws of the jurisdiction in which it was organized and has all requisite power and authority
for the ownership and operation of its properties and for the carrying on of its business as now conducted and as now proposed
to be conducted. The Company and each Subsidiary is duly licensed or qualified and in good standing as a foreign corporation or
limited liability company, as the case may be, authorized to do business in all jurisdictions wherein the character of the property
owned or leased, or the nature of the activities conducted, by it makes such licensing or qualification necessary, except where
the failure to be so qualified and in good standing would not reasonably be expected to have a material adverse effect on the Company
and its Subsidiaries, taken as a whole. Attached hereto as Exhibit 3.01 is a schedule which correctly identifies all Subsidiaries
of the Company as of the date hereof and shows with respect to each Subsidiary its jurisdiction of organization. All of the outstanding
capital stock or membership interest of each Subsidiary has been duly authorized and validly issued, is fully paid and nonassessable,
and is owned beneficially and of record by the Company or by another Subsidiary as indicated in Exhibit 3.01, free and clear
of any lien, right, encumbrance or restriction of any nature, including, without limitation, any lien, right, encumbrance or restriction
on transfer, except as is otherwise set forth in Exhibit 3.01.

 

3.02. Corporate Action. The Company
and each Subsidiary has all necessary corporate power and has taken all corporate action required to make all the provisions of
this Agreement, the Notes, the Security Documents and any other agreements and instruments executed by it in connection herewith
and therewith the valid and enforceable obligations they purport to be. The issuance of the Notes is not subject to preemptive
or other similar statutory or contractual rights and will not conflict with any provisions of any agreement or instrument to which
the Company or any Subsidiary is a party or by which it is bound.

 

3.03. Governmental Approvals.
No authorization, consent, approval, license, exemption of or filing or registration with any court or governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign, is or will be necessary for, or in connection with,
the offer, issuance, sale, execution or delivery by the Company or any Subsidiary of, or for the performance by it of its obligations
under, this Agreement, the Notes or the Security Documents, except for filings required in connection with the grant of the security
interests pursuant to the Security Documents .

 

3.04. Litigation. There is no
litigation or governmental proceeding or investigation pending or, to the knowledge of the Company, threatened against the Company
or any Subsidiary affecting any of its properties or assets, or against any officer, key employee or principal stockholder of the
Company or any Subsidiary where such litigation, proceeding or investigation, either individually or in the aggregate, would have
a material adverse effect on the Company and its Subsidiaries, taken as a whole, nor, to the knowledge of the Company, has there
occurred any event or does there exist any condition on the basis of which any litigation, proceeding or investigation might properly
be instituted. Neither the Company nor any Subsidiary, nor, to the knowledge of the Company, any officer or key employee of the
Company or any Subsidiary, or principal stockholder of the Company or any Subsidiary, is in default with respect to any order,
writ, injunction, decree, ruling or decision of any court, commission, board or other government agency affecting the Company or
any Subsidiary. There are no actions or proceedings pending or threatened (or any basis therefor known to the Company) which might
result, either in any case or in the aggregate, in any material adverse change in the business, operations, affairs or condition
of the Company and its Subsidiaries, taken as a whole, or in any of its properties or assets, or which might call into question
the validity of this Agreement, the Notes, the Security Documents or any action taken or to be taken pursuant hereto or thereto.

 

    	 	- 10 -	 

     

    

 

3.05. Compliance with Other Instruments.
The Company and each Subsidiary is in compliance in all respects with the terms and provisions of this Agreement and of its charter,
by-laws or operating agreement, as the case may be, and in all material respects with the terms and provisions of the mortgages,
indentures, leases, agreements and other instruments and of all judgments, decrees, governmental orders, statutes, rules and regulations
by which it is bound or to which its properties or assets are subject. There is no term or provision in any of the foregoing documents
and instruments which materially adversely affects the business, assets or financial condition of the Company or any Subsidiary.
Except for consent from Middlesex Savings Bank being obtained contemporaneously herewith, neither the execution and delivery of
this Agreement, the Notes or the Security Documents, nor the consummation of any transactions contemplated hereby or thereby has
constituted or resulted in or will constitute or result in a default or violation of any term or provision in any of the foregoing
documents or instruments. A consolidated schedule of Indebtedness of the Company and each Subsidiary (including lease obligations
required to be capitalized in accordance with applicable Statements of Financial Accounting Standards), as of the date of this
Agreement, is attached as Exhibit 3.05.

 

3.06. Federal Reserve Regulations.
Neither the Company nor any Subsidiary is engaged in the business of extending credit for the purpose of purchasing or carrying
margin stock (within the meaning of Regulation U of the Board of Governors of the Federal Reserve System), and no part of
the proceeds of the Notes will be used to purchase or carry any margin security or to extend credit to others for the purpose of
purchasing or carrying any margin security or in any other manner which would involve a violation of any of the regulations of
the Board of Governors of the Federal Reserve System.

forms a part of Exhibit 3.08 attached hereto, or acquired since the date of such balance sheet (except personal property
disposed of since said date in the ordinary course of business) free of any mortgages, pledges, charges, liens, security interests
or other encumbrances. The Company and each Subsidiary enjoys peaceful and undisturbed possession under all leases under which
it is operating, and all said leases are valid and subsisting and in full force and effect. The Company and each Subsidiary, to
the best of their knowledge at the time of execution, owns or has a valid right to use the patents, patent rights, licenses, permits,
trade secrets, trademarks, trademark rights, trade names or trade name rights or franchises, copyrights, inventions and intellectual
property rights being used to conduct its business as now operated and as now proposed to be operated; and the conduct of its business
as now operated and as now proposed to be operated does not and will not conflict with valid patents, patent rights, licenses,
permits, trade secrets, trademarks, trademark rights, trade names or trade name rights or franchises, copyrights, inventions and
intellectual property rights of others. Neither the Company nor any Subsidiary has any obligation to compensate any Person for
the use of any such patents or such rights nor has the Company or any Subsidiary granted to any Person any license or other rights
to use in any manner any of such patents or such rights of the Company or any Subsidiary.

(iii) neither the Company nor any Subsidiary has entered into any material transaction or made any distribution on its capital
stock except as is set forth in the Form 10-K or Form 10-Q.
