 -6- 

 
Request for Revolving Credit Loan in substantially the form attached hereto as Exhibit A, to make Revolving Credit Loans to the Borrower under the Credit
Line from time to time from the Closing Date until (but not including) the Termination Date in an aggregate principal amount of up to $500.000.00 outstanding at any one time. Disbursements of Revolving Credit Loans shall be made by wire transfer to
an account designated in writing by Borrower to Lender, or otherwise in a manner agreed upon by the Lender and the Borrower. 
  
 2.1.2 Purpose of Revolving Credit Loans. The Revolving Credit Loans may only be used for working capital purposes. 
  
 2.1.3 Interest Rate on Revolving Credit Loans;
Calculation of Interest; Payment of Interest. (a) For each day on which any amount of principal is outstanding under the Revolving Credit Loans, interest shall accrue on all principal amounts of the Revolving Credit Loans at the Base Rate
provided, however, that for each day during any period in which any Event of Default has occurred and is continuing, the rate of interest applicable to each amount of principal outstanding under the Revolving Credit Loans shall be increased to the
Default Rate. 
  
 (b) Interest on the Revolving
Credit Loans shall be calculated on the basis of a 360-day year applied to the actual number of days in each period for which interest is calculated. 
  
 (c) The Borrower shall make payments of all accrued and unpaid interest on the Revolving Credit Loans (i) on the last day of each month
during which any principal amounts are outstanding under the Revolving Credit Loans, (ii) on each date on which a mandatory prepayment is due pursuant to subsection 2.1.5(a) hereof, (iii) on the Termination Date or any earlier date on which the

make a mandatory prepayment of the Revolving Credit Loans in the amount of such excess. 
  
 (b) The Borrower, at its option, may prepay the Revolving Credit Loans or any portion thereof at any time or from time to time without
penalty or premium; provided, however that if Borrower terminates the Credit Facility within 12 months of its commencement, the Borrower shall pay to Lender a penalty equal to the average of the interest charged for the 90 day period (or such
shorter period if the termination occurs prior to 90 days) prior to the 

  

 -7- 

 
termination of the Credit Facility for each month or portion thereof that Credit Facility has been terminated prior to the expiration of the first 12 months
of the Credit Facility. 
  
 Section 2.2 Credit for
Payments. The Lender shall have no obligation to give any credit against the Obligations except upon its receipt of available funds in the amount of the credit to be given. If the Lender, in its sole discretion in each instance, elects to give
provisional credit against any item before collection of the funds represented thereby, and such funds are not received by the Lender within any period of time within which the Lender customarily requires such funds to be collected, the provisional
credit theretofore given shall be reversed as of the time it was given. Each payment received by the Lender after 2:00 p.m. on any Business Day and each payment received by the Lender on any day which is not a Business Day shall be deemed to be
received on the next following Business Day.

Revolving Credit Loans and each payment of interest received by the Lender on the Revolving Credit Loans and such records shall be presumed correct, absent manifest error; provided, however, that the failure of the Lender to make such a
notation or any error therein shall not in any manner affect the obligation of the Borrower to repay the Revolving Credit Loans in accordance with the terms of this Agreement and the Note. 
  
 Section 2.4 Reinstatement of Avoided Payments. If any amount received
by the Lender on account of the Obligations is required to be returned or paid to any Borrower or any other Person pursuant to any insolvency or bankruptcy Law or for any other reason (each such amount, together with any interest required to be paid
by the Lender thereon, is referred to as an “Avoided Payment”), then as of the date the Lender makes such return or other payment: the amount of the Avoided Payment shall be reinstated as principal of a Revolving Credit Loan bearing
interest at the Default Rate, and all such amounts shall be immediately due and payable (without presentment, demand, notice of default or protest, all of which are hereby waived by the Borrower). The provisions of this Section shall survive the
termination of this Agreement. 
  
 Section 2.5 Lender’s
Stock Conversion Rights. Lender shall, at any time and from time to time prior to the termination of the Credit Facility, have the right to convert any unpaid loan principal or any portion thereof and any accrued and unpaid interest thereon into
Common Stock at the Conversion Price (subject to adjustment as set forth herein); provided, however, at no time shall Lender have the right to convert any unpaid loan principal or any portion thereof or accrued and unpaid interest thereon into
shares of common stock of the Borrower if upon such 

  

 -8- 

 
conversion, Lender would be deemed to be the beneficial owner (as defined in Rule 13(d)-3 of the Securities Exchange Act of ’34) of 5% or more of the
then outstanding common stock of the Borrower. At the Lender’s option, the amount of accrued and unpaid interest shall not be subject to conversion but instead may be paid in cash as of the next interest payment date; if the Lender elects to
convert the amount of accrued and unpaid interest into common stock of the Borrower, the common stock issued to the Lender shall be valued at the then applicable conversion price. At all times, Borrower shall maintain authorized and unissued shares
of its common stock equal to at least 150% of the number of shares of common stock issuable upon conversion of the outstanding loan principal and accrued and unpaid interest thereon. The Lender’s Conversion Rights are more fully set forth in
the Note. 
  
 Section 2.6 Borrower’s Challenge of Lender
Rights. If at any time after the date of this Agreement, (i) the Borrower challenges, disputes or denies the right of the Lender to effect the conversion of the unpaid principal or any portion thereof or any accrued and unpaid interest thereon
into common stock of the Borrower or otherwise dishonors or rejects any notice of conversion delivered by the Lender or (ii) any third party who is not and has never been an Affiliate of the Lender commences any lawsuit or proceeding or otherwise
asserts any claim before any court or public or governmental authority which seeks to challenge, deny, enjoin, limit, modify, delay or dispute the right of the Lender hereof to effect such conversion, then the Lender shall have the right, by written
notice to the Borrower, to require the Borrower to promptly redeem the outstanding amount of the Convertible Revolving Credit Line Note for cash at a redemption price equal to 125% of the then outstanding principal amount together with all accrued
and unpaid interest thereon (the “Mandatory Purchase Amount”). Under any of the circumstances set forth above, the Borrower shall be responsible for the payment of all costs and expenses of the Lender, including reasonable legal fees and
expenses, as and when incurred in disputing any such action or pursuing its rights hereunder (in addition to any other rights of the Lender). 
  
 SECTION 2.7 Reclassification. Consolidation, Merger or Mandatory Share Exchange. 
  
 (a) In case of any stock split or reverse stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting the Common Stock of the Borrower (each, an “Adjustment”), the Conversion Rate in effect at the time of the effective date for such Adjustment shall be
proportionally adjusted so that the Lender after such date shall be entitled to receive the aggregate number and kind of shares which, if the Note had been converted by Lender immediately prior to such date, the Lender would have owned upon such
conversion and been entitled to receive upon such Adjustment (and for such purposes the Lender shall, to the extent relevant, be deemed to have converted the Note immediately prior to the record date or the effective date, as the case may, for the
Adjustment). For example, if the Borrower declares a 2:1 stock dividend or stock split and the Conversion Price immediately prior to the record date for such Adjustment was $1.00 per share, the adjusted Conversion Price immediately after the
Adjustment would be $.50 per share. Such adjustment may be made successively if there is more than one Adjustment. In all other respects the provisions of this Section shall be applied in a fair, equitable and reasonable manner so as to give effect,
as nearly as may be, to the purposes hereof. A rights offering to stockholders shall be deemed a stock dividend to the extent of the bargain purchase element of the rights. The provisions of this Section 2.7 shall similarly apply to successive
reclassifications, changes, consolidations, mergers, mandatory share exchanges and sales and transfers. 
  

 -9- 

 (b) If, for any reason, prior to the conversion of the Note in full, the Borrower spins off or otherwise
divests itself of a part of its business or operations or disposes all or of a part of its assets in a transaction (the “Spin Off”) in which the Borrower does not receive compensation for such business, operations or assets, but causes
securities of another entity (the “Spin Off Securities”) to be issued to security holders of the Borrower, then the Borrower shall cause (i) to be reserved Spin Off Securities equal to the number thereof which would have been issued to the
Lender had all of the Lender’s unconverted portion of the Note outstanding on the record date (the “Record Date”) for determining the amount and number of Spin Off Securities to be issued to security holders of the Borrower (the
“Outstanding Note”) been converted as of the close of business on the Trading Day immediately before the Record Date (the “Reserved Spin Off Shares”), and (ii) to be issued to the Lender on the conversion of all or any of the
Outstanding Note, such amount of the Reserved Spin Off Shares equal to (x) the Reserved Spin Off Shares multiplied by (y) a fraction, of which (I) the numerator is the amount of the Outstanding Note then being converted, and (II) the denominator is
the amount of the Outstanding Note. 
  
 SECTION 2.8 Conversion
Price Adjustments. The Conversion Price shall be subject to adjustment from time to time as follows: 
  
 2.8.1 Common Stock Issued at Less Than the Conversion Price. If the Borrower shall issue any Common Stock other than Excluded Stock
(as hereinafter defined) without consideration or for a consideration per share less than the Conversion Price in effect immediately prior to such issuance, the Conversion Price in effect immediately prior to each such issuance shall immediately
(except as provided below) be reduced to the price equal to the lowest per share consideration received or to be received by the Borrower in connection with such issuance. 
  
 For the purposes of any adjustment of the Conversion Price pursuant to this Section 2.8.1, the following provisions shall be
applicable: 
  
 2.8.1.1 Cash. In the case
of the issuance of Common Stock for cash, the amount of the consideration received by the Borrower shall be deemed to be the amount of the cash proceeds received by the Borrower for such Common Stock before deducting there from any discounts,
commissions, taxes or other expenses allowed, paid or incurred by the Borrower for any underwriting or otherwise in connection with the issuance and sale thereof. 
  
 2.8.1.2 Consideration Other Than Cash. In the case of the issuance of Common Stock (other than upon
the conversion of shares of capital stock or other securities of the Borrower) for a consideration in whole or in part other than cash, including securities acquired in exchange therefor (other than securities by their terms so exchangeable), the
consideration other than cash shall be deemed to be the fair value thereof as determined by the Board of Directors, irrespective of any accounting treatment. 
  

 -10- 

 2.8.1.3 Options and Convertible Securities. In the case of the issuance of (i)
options, warrants or other rights to purchase or acquire Common Stock (whether or not at the time exercisable), (ii) securities by their terms convertible into or exchangeable for Common Stock (whether or not at the time so convertible or
exchangeable) or options, warrants or rights to purchase such convertible or exchangeable securities (whether or not at the time exercisable): 
  
 (i) The aggregate maximum number of shares of Common Stock deliverable upon exercise of such options, warrants or other rights to purchase
or acquire Common Stock shall be deemed to have been issued at the time such options, warrants or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Subsections 2.8.1.1 and 2.8.1.2 above), if
any, received by the Borrower upon the issuance of such options, warrants or rights plus the minimum purchase price provided in such options, warrants or rights for the Common Stock covered thereby; 
  
 (ii) The aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange for any such convertible or exchangeable securities, or upon the exercise of options, warrants or other rights to purchase or acquire such convertible or exchangeable securities and the subsequent
conversion or exchange thereof, shall be deemed to have been issued at the time such securities were issued or such options, warrants or rights were issued and for a consideration equal to the consideration, if any, received by the Borrower for any
such securities and related options, warrants or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration (determined in the manner provided in Sections 2.8.1.1 and 2.8.1.2), if any,
to be received by the Borrower upon the conversion or exchange of such securities, or upon the exercise of any related options, warrants or rights to purchase or acquire such convertible or exchangeable securities and the subsequent conversion or
exchange thereof; 
  
 (iii) On any change in the
number of shares of Common Stock deliverable upon exercise of any such options, warrants or rights or conversion or exchange of such convertible or exchangeable securities or any change in the consideration to be received by the Borrower upon such
exercise, conversion or exchange, including, but not limited to, a change resulting from the anti-dilution provisions thereof, the Conversion Price as then in effect shall forthwith be readjusted to such Conversion Price as would have been obtained
had an adjustment been made upon the issuance of such options, warrants or rights not exercised prior to such change, or of such convertible or exchangeable securities not converted or exchanged prior to such change, upon the basis of such change;

  
 (iv) On the expiration or cancellation of any
such options, warrants or rights, or the termination of the right to convert or exchange such convertible or exchangeable securities, if the Conversion Price shall have been adjusted upon the issuance thereof, the Conversion Price shall forthwith be
readjusted to such Conversion Price as would have been obtained had an adjustment been made upon the issuance of such options, warrants, rights or such convertible or exchangeable securities on the basis of the issuance of only the number of shares
of Common Stock actually issued upon the exercise of such options, warrants or rights, or upon the conversion or exchange of such convertible or exchangeable securities; and 
  

 -11- 

 (v) If the Conversion Price shall have been adjusted upon the issuance of any such
options, warrants, rights or convertible or exchangeable securities, no further adjustment of the Conversion Price shall be made for the actual issuance of Common Stock upon the exercise, conversion or exchange thereof; (provided, however, that no
increase in the Conversion Price shall be made pursuant to subclauses (i) and (ii) of this Section 2.8.1.3.

warrants or any other convertible security of the Borrower issued as of the date hereof. 
  
 2.8.3 Rounding of Calculations; Minimum Adjustment. All calculations under this subparagraph (f) shall be made to the nearest cent
or to the nearest one hundredth (1/100th) of a share, as the case may be. Any provision of this paragraph to the contrary notwithstanding, no adjustment in the Conversion Price shall be made if the amount of such adjustment would be less than $0.05,
but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall
aggregate $0.05 or more. 
  
 2.8.4 Timing of
Issuance of Additional Common Stock Upon Certain Adjustments. In any case in which the provisions of this paragraph shall require that an adjustment shall become effective immediately after a record date for an event, the Borrower may defer
until the occurrence of such event (A) issuing to the Lender converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such
event over and above the shares of Common Stock issuable upon such conversion before giving effect to such adjustment and (B) paying to Lender any amount of cash in lieu of a fractional share of Common Stock pursuant to Subsection 2.8.5 of this
Section; provided, that, the Borrower upon request shall deliver to such Lender a due bill or other appropriate instrument evidencing such Lender’s right to receive such additional shares, and such cash, upon the occurrence of the event
requiring such adjustment. 
  
 2.8.5 Statement
Regarding Adjustments. Whenever the Conversion Price shall be adjusted as provided herein, the Borrower shall forthwith file at the principal office of the Borrower, a statement showing in detail the facts requiring such adjustment and the
Conversion Price that shall be in effect after such adjustment, and the Borrower shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to Lender at its address appearing on the Borrower’s records. Each such
statement shall be signed by the Borrower’s independent public accountants, if applicable. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of subparagraph
(i).

to any such action and the approximate date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of 

  

 -12- 

 
such action (to the extent such effect may be known at the date of such notice) on the Conversion Price and the number, kind or class of shares or other
securities or property which shall be deliverable upon conversion of the Note. In the case of any action which would require the fixing of a record date, such notice shall be given at least twenty (20) days prior to the date so fixed, and in case of
all other action, such notice shall be given at least fifteen (15) days prior to the taking of such proposed action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action. 
  
 2.8.7 Costs. The Borrower shall pay all documentary,
stamp, transfer or other transactional taxes attributable to the issuance or delivery of shares of Common Stock upon conversion of any amount of the Note; provided that the Borrower shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the Lender or the individual or entity in respect of which such shares are being issued. 
  
 Section 2.9 Registration Rights. 
  
 2.9.1 Right to Piggyback. 
  
 2.9.1.1 If Borrower proposes to register any securities of
Borrower under the Securities Act on any registration form (otherwise than for the registration of securities to be offered and sold by Borrower pursuant to (i) an employee benefit plan, (ii) a dividend or interest reinvestment plan, (iii) other
similar plans or (iv) reclassification of securities, mergers, consolidations and acquisitions of assets) permitting a secondary offering or distribution, not less than 90 days prior to each such registration Borrower shall give to the Lender
written notice of such proposal which shall describe in detail the proposed registration and distribution (including those jurisdictions where registration or qualification under the securities or blue sky laws is intended) and, upon the written
request of Lender furnished within 30 days after the date of any such notice, proceed to include in such registration such shares of Borrower owned by Lender (“Piggy-Back Shares”) as have been requested by the Lender to be included in such
registration. The Lender shall in its request describe briefly the proposed disposition of such shares of Common Stock. Borrower will in each instance use its best efforts to cause all such Piggy-Back Shares to be registered under the Securities Act
and qualified under the securities or blue sky laws of any jurisdiction requested by the Lender, all to the extent necessary to permit the sale or other disposition thereof (in the manner stated in such request) by the Lender. 
  
 2.9.1.2 If the managing underwriter, who shall be selected
by Borrower advises Borrower in writing that, in its opinion, the inclusion of the Piggy-Back Shares with the securities being registered by Borrower would materially adversely affect the distribution of all such securities, then Borrower will
include in such registration (i) the securities Borrower proposes to sell and (ii) the Piggy-Back Shares requested to be included in such registration, on a pro rata basis between Borrower and Lender. 
  
 2.9.2. Selection of Underwriter; Participation in
Underwritten Registrations. Lender agrees to the selection by Borrower of the underwriter to manage such registration and to execute an underwriting agreement with such underwriter that is in customary form. Lender may not participate in any
registration hereunder which is underwritten unless Lender (i) agrees to sell its 

  

 -13- 

 
Piggy-Back Shares on the basis provided in any underwriting arrangements approved by Borrower, and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements; provided that Lender shall not be required to make any representations or warranties to Borrower or the underwriters other
than representations and warranties regarding the Lender and the Lender’s intended method of distribution. 
  
 2.9.3 Withdrawal of Registration. Nothing in this Section shall be deemed to require Borrower to proceed with any registration of
its securities after giving the notice as provided herein; provided, however, that Borrower shall pay all expenses incurred pursuant to such notice in accordance with Section 2.9.6 
  
 2.9.4 Registration and Qualification Procedures.
Whenever Borrower is required by the provisions of this Section to use its best efforts to effect the registration of any of its securities under the Securities Act, Borrower will, as expeditiously as is possible: 
  
 (i) prepare and file with the SEC a registration statement
with respect to such securities in connection with which Borrower will give Lender, its counsel and accountants the opportunity to participate in the preparation of such registration statement, each prospectus included therein or filed with the SEC,
and each amendment thereof or supplement thereto, and will give Lender such access to its books and records and such opportunities to discuss the business of Borrower with its officers and the independent public accountants who have certified its
financial statements as shall be necessary, in the opinion of the Lender’s counsel, to conduct a reasonable investigation within the meaning of the Securities Act; 
  
 (ii) prepare and file with the SEC such amendments and supplements to such registration statement and the
prospectus used in connection therewith as may be necessary to keep such registration statement effective and the prospectus current and to comply with the provisions of the Securities Act with respect to the sale of all securities covered by such
registration statement whenever the Lender shall desire to sell the same; provided, however, Borrower shall have no obligation to file any amendment or supplement at its own expense more than nine months after the effective date of such
registration statement; 
  
 (iii) furnish to the
Lender such number of copies of preliminary prospectuses and prospectuses and each supplement or amendment thereto and such other documents as they may reasonably request in order to facilitate the sale or other disposition of the securities owned
by Lender in conformity with (i) the requirements of the Securities Act and (ii) the proposed method of distribution; 
  
 (iv) use its reasonable best efforts to register or qualify the securities covered by such registration statement under the securities or
blue sky laws of such jurisdictions within the United States as the Lender shall reasonably request, and do such other reasonable acts and things as may be required of it to enable the Lender to conclude the sale or other disposition in such
jurisdictions of the securities owned by them; provided, however, that Borrower shall not be required to (a) qualify as a foreign corporation or consent to a general and unlimited service of process in any such jurisdiction, (b) subject
itself to any material taxation in any such jurisdiction, or (iii) qualify as a dealer in securities; 
  

 -14-

 -16- 

 
furnished any amendments or supplements thereto) or caused by any omission, or alleged omission, to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses are caused by any untrue statement or alleged untrue statement or omission or alleged omission based upon
information ‘furnished in writing to Borrower by either Lender or any underwriter expressly for use therein. 
  
 2.9.7.2. In connection with any registration or qualification of securities under this Section, the Lender agrees to indemnify Borrower
and each officer, director and controlling person of Borrower against all losses, claims, damages, liabilities and expenses (including the costs of reasonable investigation) caused by any untrue, or alleged untrue, statement of a material fact
contained in any registration statement, preliminary prospectus, prospectus or notification or offering circular (as amended or supplemented if Lender shall have furnished information for any amendments or supplements thereto) or caused by any
omission, or alleged omission, to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent such losses, claims, damages, liabilities or expenses are caused by any

the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect
to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any
settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees

person of such indemnified party and will survive the transfer of Piggy-Back Shares. 
  
 2.9.7.5 The parties agree to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in
the event indemnification is unavailable for any reason. Such right to contribution shall be in such proportion as is appropriate to reflect the relative fault of and benefits to Borrower on the one hand and the Lender on the other, in connection
with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits to the indemnifying party and indemnified parties shall be
determined by reference to, among other things, the total proceeds received by the indemnifying party and indemnified parties in connection with the offering to which such losses, claims, damages, liabilities or expenses relate. The relative fault
of the indemnifying party and indemnified parties shall be determined by reference to, among other 

  

 -17- 

 
things, whether the action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission or state a
material fact, has been made by, or relates to information supplied by, such indemnifying party or the indemnified parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.
The parties hereto agree that it would not be just or equitable if contribution pursuant hereto were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in
this Section. No person found guilty of any fraudulent misrepresentation (within the meaning of Section ll(f) of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation.

fee equal to one (1%) percent of the Credit Facility, which amount shall be paid to Lender on the initial Closing Date. All such costs and expenses shall be payable by the Borrower to the Lender upon demand or as otherwise agreed by the Lender, and
shall constitute a part of the Obligations. The Borrower shall hold the Lender harmless from and against any and all claims or liabilities (now existing or hereafter arising) with respect to the foregoing or resulting from any delay or failure in
the payment of the same. The Borrower’s duty to pay such amounts shall survive the termination of the Lender’s agreements hereunder and the payment and satisfaction of the Obligations.

 Section 8.8 Severability. In case any one or more of
the provisions contained in this Agreement or the other Loan Documents should be invalid, illegal or unenforceable in any respect in any jurisdiction, the validity, legality and enforceability of such provisions shall not be affected or impaired in
any other jurisdiction, nor shall the remaining provisions contained herein and therein in any way be affected or impaired thereby. 
  
 Section 8.9 Choice Of Law. The laws of the State of New York (excluding, however, conflict of law principles) shall govern and be applied to
determine all issues relating to this Agreement and the rights and obligations of the parties hereto, including the validity, construction, interpretation, and enforceability of this Agreement and its various provisions and the consequences and
legal effect of all transactions and events which resulted in the execution of this Agreement or which occurred or were to occur as a direct or indirect result of this Agreement having been executed. 
  
 Section 8.10 Consent To Jurisdiction; Agreement As To Venue. Each
party irrevocably consents to the exclusive jurisdiction of the federal and state courts located in New York County, New York. Any action brought by any party hereto which is based, directly or indirectly, on this Agreement or any other Loan
Document or any matter in or related to this Agreement or any other Loan Document, including but not limited to the making of the Loans or the administration or collection thereof shall be brought only in the said courts. Each party waives any right
to object to the maintenance of a suit in said court on the basis of improper venue or of inconvenience of forum. The Borrower acknowledges and agrees that the choice of forum contained in this Section shall not be deemed to preclude the enforcement
of any judgment obtained hereunder or under any other Loan Document in any forum or the taking of any action under the Loan Documents to enforce the same in the appropriate jurisdiction.

first page hereof as the effective date, independent of the date of each parties’ execution or delivery hereof. 
  
 Section 8.12 Counterparts. This Agreement and each amendment hereto may be executed in counterparts, each of which, considered together, shall

this Agreement agrees that any suit, action, or proceeding, whether claim or counterclaim, brought or instituted by either party hereto or any successor or assign of any party on or with respect to this Agreement or any other Loan Document or which
in any way relates, directly or indirectly, to the Loan or any event, transaction, or occurrence arising out of or in any way connected with the Loan, or the dealings of the parties with respect thereto, shall be tried only by a court and not by a
jury. EACH PARTY HEREBY EXPRESSLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY SUCH SUIT, ACTION, OR PROCEEDING. This Section is a specific and material aspect of this Agreement among the parties.
