have been sooner terminated in accordance with Section 19 hereof. 
  
 b. Except as specifically provided herein, the acquisition of Common Stock on any Purchase Date through participation in the Plan shall neither limit nor require the acquisition of Common Stock by a Participant on any

 5. PARTICIPATION. 
  
 a. GENERAL. All Employees eligible to participate in the Plan as of the Effective Date shall automatically
become Participants in the initial Purchase Interval and be eligible to purchase shares of Common Stock on the Purchase Date of the initial Purchase Interval. All Employees eligible to participate in the Plan as of the first day of subsequent
Purchase Intervals shall automatically become Participants in such Purchase Intervals and be eligible to purchase shares of Common Stock on the Purchase Date of such Purchase Intervals. Notwithstanding the automatic participation in the Purchase
Intervals by all eligible Employees, no shares of Common Stock shall be purchased on behalf of a Participant on the Purchase Date of a Purchase Interval unless a Participant has filed a subscription agreement in accordance with Section 6 hereof.

  
 b. PURCHASE OF SHARES. An eligible Employee
may purchase shares of Common Stock by completing a subscription agreement in the form of Exhibit 1 to this Plan (or such other form or method (including electronic forms) as the Administrator may designate from time to time) and filing it (as well
as a direct payment, if applicable) with the Company at least three (3) business days prior to the next Purchase Date, unless a later time for filing the subscription agreement is set by the Administrator for all eligible Employees with respect to a
given Purchase Date. 
  
 6. PAYROLL DEDUCTIONS AND DIRECT PAYMENT.

  
 a. At the time a Participant files a
subscription agreement, the Participant may elect to have payroll deductions made during the Purchase Interval in either (i) amounts between one percent (1%) and not exceeding ten percent (10%) of the Compensation which the Participant receives
during the Purchase Interval or (ii) fixed dollar amounts not exceeding ten percent (10%) of the Compensation which the Participant receives during the Purchase Interval. All payroll deductions made for a Participant shall be credited to the
Participant’s account under the Plan and will be withheld in either whole percentages or whole dollar amounts. Payroll deductions shall commence with the first partial or full payroll period beginning after the Participant’s submission of
a subscription agreement and shall end on the last complete payroll period prior to a Purchase Date, unless sooner terminated by the Participant as provided in Section 10. 
  
 b. A Participant may make one or more direct payments into his or her account by completing and filing with
the Company either (i) a subscription agreement in the form of Exhibit 1 to this Plan or (ii) a notice in the form of Exhibit 2 to this Plan (or such other form or method (including electronic forms) as the Administrator may designate from time to
time) designating the amount of the direct payment. Notwithstanding the foregoing, the total amount of the direct payment(s) and the payroll deductions pursuant to Section 6(a) may not exceed ten percent (10%) of the Compensation which the
Participant receives during the Purchase Interval. 
  
 c. A Participant may discontinue participation in a Purchase Interval as provided in Section 10, or may increase or decrease the rate of payroll deductions during the Purchase Interval by completing and filing with the Company a notice in
the form of Exhibit 2 to 

  

 5 








 
this Plan (or such other form or method (including electronic forms) as the Administrator may designate from time to time) authorizing an increase or
decrease in the payroll deduction rate. Any increase or decrease in the rate of a Participant’s payroll deductions shall be effective with the first full payroll period commencing ten (10) business days after the Company’s receipt of such
notice unless the Company elects to process a given change in participation more quickly. A Participant’s subscription agreement (as modified by any subsequently filed notice) shall remain in effect for successive Purchase Dates unless
terminated as provided in Section 10. The Administrator shall be authorized to limit the number of payroll deduction rate changes during any Purchase Interval. 
  

d. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) herein, a
Participant’s payroll deductions shall be decreased to 0% or zero dollars and one or more direct payments made by the Participant pursuant to Section 6(b) may be rejected by the Administrator and returned to the Participant. Payroll deductions
shall recommence at the rate provided in such Participant’s subscription agreement, as amended, at the time when permitted under Section 423(b)(8) of the Code and Section 3(b) herein, unless such participation is sooner terminated by the
Participant as provided in Section 10. 
  
 7. MAXIMUM SHARE
PURCHASE. On a Purchase Date, each Participant may purchase (at the applicable Purchase Price) no more than two hundred and fifty (250) shares of Common Stock, subject to adjustment as provided in Section 18 hereof; provided that such purchase of
shares shall be subject to the limitations set forth in Sections 3(b), 6 and 12 hereof. The purchase of shares on the applicable Purchase Date shall occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10.

  
 8. PURCHASE OF SHARES. Unless a Participant withdraws from a
Purchase Interval as provided in Section 10, below, shares of Common Stock will be automatically purchased for a Participant on each Purchase Date, by applying the accumulated payroll deductions and direct payments (if any) in the Participant’s
account to purchase the number of full shares determined by dividing such Participant’s payroll deductions and direct payments (if any) accumulated prior to such Purchase Date and retained in the Participant’s account as of the Purchase
Date by the applicable Purchase Price. No fractional shares will be purchased; any amount remaining in a Participant’s account which is not sufficient to purchase a full share shall be carried over to the next Purchase Date or returned to the
Participant, if the Participant withdraws from the Plan. Notwithstanding the foregoing, any amount remaining in a Participant’s account following the purchase of shares on the Purchase Date due to the application of Section 423(b)(8) of the
Code or Section 7, above, shall be returned to the Participant and shall not be carried over to the next Purchase Date. 
  
 9. DELIVERY AND SALE OF SHARES. Within ten (10) calendar days after the applicable Purchase Date, the Company will deliver the Shares purchased on such
Purchase Date to the Participant’s account maintained by the Company’s designated broker. In no event may a Participant sell Shares acquired on a Purchase Date prior to the delivery of such Shares to the Participant’s account
maintained by the Company’s designated broker. 
  

 6 








 10. WITHDRAWAL; TERMINATION OF EMPLOYMENT. 
  
 a. A Participant may either (i) withdraw all but not less than all the payroll deductions and direct
payments (if any) credited to the Participant’s account and not yet used to purchase shares under a Purchase Interval or (ii) terminate future payroll deductions, but allow accumulated payroll deductions and prior direct payments (if any) to be
used to purchase shares on the next Purchase Date at any time by giving written notice to the Company in the form of Exhibit 2 to this Plan (or such other form or method (including electronic forms) as the Administrator may designate from time to
time). If the Participant elects withdrawal alternative (i) described above, all of the Participant’s payroll deductions and direct payments (if any) credited to the Participant’s account will be paid to such Participant as promptly as
practicable after receipt of notice of withdrawal and no further payroll deductions for the purchase of shares will be made during the Purchase Interval; provided that notice in the form of Exhibit 2 to this Plan (or such other form or method
(including electronic forms) as the Administrator may designate from time to time) is delivered to the Company at least ten (10) business days prior to the next Purchase Date. If the Participant elects withdrawal alternative (ii) described above, no
further payroll deductions for the purchase of shares will be made during the Purchase Interval, all of the Participant’s payroll deductions and direct payments (if any) credited to the Participant’s account will be applied to the purchase
of shares on the next Purchase Date (subject to Sections 3(b), 6, 7 and 12) and all remaining accumulated payroll deduction amounts shall be returned to the Participant. If a Participant withdraws from a Purchase Interval, payroll deductions will
not resume at the beginning of the succeeding Purchase Interval unless the Participant delivers to the Company a new subscription agreement. 
  
 b. Upon termination of a Participant’s employment relationship (as described in Section 2(k)) at any time, the payroll deductions and
direct payments (if any) credited to such Participant’s account during the Purchase Interval but not yet used to purchase shares will be applied to the purchase of Common Stock on the next Purchase Date, unless the Participant (or in the case
of the Participant’s death, the person or persons entitled to the Participant’s account balance under Section 14) withdraws from the Plan by submitting a notice in accordance with subsection (a) of this Section 10. In such a case, the
payroll deductions and direct payments (if any) credited to such Participant’s account during the Purchase Interval but not yet used to purchase shares will be returned to such Participant or, in the case of his/her death, to the person or
persons entitled thereto under Section 14. 
  
 11. INTEREST. No
interest shall accrue on the payroll deductions and direct payments (if any) credited to a Participant’s account under the Plan. 
  
 12. STOCK. 
  
 a. The maximum number of shares of Common Stock which shall be made available for sale under the Plan shall be one million (1,000,000)
shares, subject to adjustment upon changes in capitalization of the Company as provided in Section 18. With respect to any amendment to increase the total number of shares of Common Stock under the Plan, the Administrator shall have discretion to
disallow the purchase of any increased shares of Common Stock for the Purchase Interval in existence at the time of such increase. If the Administrator determines that on a given Purchase Date the number of shares that may be purchased may 

  

 7 








 
exceed the number of shares then available for sale under the Plan the Administrator may make a pro rata allocation of the shares remaining available for
purchase on such Purchase Date. Any amount remaining in a Participant’s payroll account following such pro rata allocation shall be returned to the Participant and shall not be carried over to any future Purchase Date, as determined by the
Administrator. 
  
 b. Shares to be delivered to a
Participant under the Plan will be registered in the name of the Participant or in the name of the Participant and his or her spouse, as designated in the Participant’s subscription agreement. 
  
 13. ADMINISTRATION. The Plan shall be administered by the Administrator which
shall have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and to adjudicate all disputed claims filed under the Plan. Any question or dispute regarding the administration
or interpretation of the Plan shall be submitted by the Participant or by the Company to the Administrator. The resolution of such question or dispute as well as every finding, decision and determination made by the Administrator shall, to the full
extent permitted by Applicable Law, be final and binding upon all persons. 
  
 14. DESIGNATION OF BENEFICIARY. 
  
 a. Each Participant will file a written designation of a beneficiary who is to receive any shares and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death. If
a Participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective. 
  
 b. Such designation of beneficiary may be changed by the Participant (and the Participant’s spouse, if any) at any time by written
notice. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living (or in existence) at the time of such Participant’s death, the Company shall deliver such shares and/or cash
to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Administrator), the Administrator shall deliver such shares and/or cash to the spouse (or domestic
partner, as determined by the Administrator) of the Participant, or if no spouse (or domestic partner) is known to the Administrator, then to the issue of the Participant, such distribution to be made per stirpes (by right of representation), or if
no issue are known to the Administrator, then to the heirs at law of the Participant determined in accordance with Section 27. 
  
 15. TRANSFERABILITY. No payroll deductions or direct payments credited to a Participant’s account or any rights with regard to the purchase of shares
under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in Section 14 hereof) by the Participant. Any such attempt at assignment, transfer,
pledge or other disposition shall be without effect, except that the Administrator may, in its sole discretion, treat such act as an election to withdraw funds in accordance with Section 10. 
  
 16. USE OF FUNDS. All payroll deductions and direct payments (if any)
received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the 

  

 8 








 
Company shall not be obligated to segregate such payroll deductions and direct payments (if any) or hold them exclusively for the benefit of Participants.
All payroll deductions and direct payments (if any) received or held by the Company may be subject to the claims of the Company’s general creditors. Participants shall have the status of general unsecured creditors of the Company. Any amounts
payable to Participants pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended. The Company shall retain at all
times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant account shall not
create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Designated Parent or Subsidiary and a Participant, or otherwise create any vested or beneficial interest in any Participant or the
Participant’s creditors in any assets of the Company or a Designated Parent or Subsidiary. The Participants shall have no claim against the Company or any Designated Parent or Subsidiary for any changes in the value of any assets that may be
invested or reinvested by the Company with respect to the Plan. 
  
 17. REPORTS. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to Participants at least annually, which statements will set forth the amounts of payroll deductions and direct
payments (if any), the Purchase Price, the number of shares purchased and the remaining cash balance, if any. 
  
 18. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS. 
  
 a. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. Subject to any required action by the stockholders of the
Company, the Reserves, the maximum number of shares that may be purchased on any Purchase Date, as well as any other terms that the Administrator determines require adjustment may be proportionately adjusted for (i) any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, (ii) any other increase or decrease in the number of issued shares of Common Stock
effected without receipt of consideration by the Company, or (iii) as the Administrator may determine in its discretion, any other transaction with respect to Common Stock including a corporate merger, consolidation, acquisition of property or
stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation (whether partial or complete) or any similar transaction; provided, however that conversion of any convertible securities of the Company
shall not be deemed to have been “effected without receipt of consideration.” Such adjustment, if any, shall be made by the Administrator and its determination shall be final, binding and conclusive. Except as the Administrator determines,
no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason hereof shall be made with respect to the Reserves. 
  
 b. CORPORATE TRANSACTIONS. In the event of a proposed
Corporate Transaction, each stock purchase right under the then existing Purchase Interval under the Plan shall be assumed by such successor corporation or a parent or subsidiary of such successor corporation, unless the Administrator, in the
exercise of its sole discretion and in lieu of such assumption, determines to shorten the Purchase Interval then in progress by setting a new Purchase Date (the 

  

 9 








 
“New Purchase Date”). If the Administrator shortens the Purchase Interval then in progress in lieu of assumption in the event of a Corporate
Transaction, the Administrator shall notify each Participant in writing at least ten (10) business days prior to the New Purchase Date, that the Purchase Date has been changed to the New Purchase Date and that EITHER: 
  
 (1) the Participant will purchase shares on the New Purchase
Date, unless prior to such date the Participant has withdrawn from the Purchase Interval as provided in Section 10; or 
  
 (2) the Company shall pay to the Participant on the New Purchase Date an amount in cash, cash equivalents, or property as determined by
the Administrator that is equal to the excess, if any, of (i) the Fair Market Value of the shares over (ii) the Purchase Price due had the Participant purchased shares under Subsection (b)(1) above. In addition, all remaining accumulated payroll
deduction amounts and direct payments (if any) shall be returned to the Participant. 
  
 c. For purposes of Subsection 18, a stock purchase right under the then existing Purchase Interval under the Plan shall be deemed to be
assumed if, in connection with the Corporate Transaction, the stock purchase right is replaced with a comparable stock purchase right with respect to shares of capital stock of the successor corporation or Parent thereof. The determination of
comparability shall be made by the Administrator prior to the Corporate Transaction and its determination shall be final, binding and conclusive on all persons. 
  

19. AMENDMENT OR TERMINATION. 
  
 a. The Administrator may at any time and for any reason terminate or amend the Plan. Except as provided in Section 18, no such termination
can adversely affect the purchase rights of a Participant with respect to the then existing Purchase Interval under the Plan, provided that the Plan or then existing Purchase Interval may be terminated by the Administrator establishing an earlier
Purchase Date with respect to the Purchase Interval then in progress if the Administrator determines that the termination of the Plan or such Purchase Interval is in the best interests of the Company and its stockholders. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision or any other Applicable Law), the Company shall obtain stockholder approval of any amendment in such a manner and to such a degree as required. 
  
 b. Without stockholder consent, the Administrator shall be
entitled to limit the frequency and/or number of changes in the amount withheld during Purchase Intervals, determine the length of any future Purchase Intervals, establish the exchange ratio applicable to amounts withheld in a currency other than
U.S. dollars, establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for
delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of
Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion 

  

 10 








 
advisable and which are consistent with the Plan, in each case to the extent consistent with the requirements of Code Section 423 and other Applicable Laws.

  
 20. NOTICES. All notices or other communications by a
Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Administrator at the location, or by the person, designated by the Administrator for the receipt
thereof. 
  
 21. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall
not be issued under the Plan unless the purchase and the issuance and delivery of such shares shall comply with all Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a
condition to the purchase of shares on a Purchase Date, the Company may require the Participant to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to
sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned Applicable Laws or is otherwise advisable. In addition, no shares shall be purchased hereunder before the
Plan shall have been approved by stockholders of the Company as provided in Section 23. 
  
 22. TERM OF PLAN. The Plan shall become effective upon its approval by the stockholders of the Company. It shall continue in effect for a term of twenty (20) years unless sooner terminated under Section 19.

  
 23. NO EMPLOYMENT RIGHTS. The Plan does not, directly or
indirectly, create any right for the benefit of any employee or class of employees to purchase any shares under the Plan, or create in any employee or class of employees any right with respect to continuation of employment by the Company or a
Designated Parent or Subsidiary, and it shall not be deemed to interfere in any way with such employer’s right to terminate, or otherwise modify, an employee’s employment at any time. 
  
 24. NO EFFECT ON RETIREMENT AND OTHER BENEFIT PLANS. Except as specifically
provided in a retirement or other benefit plan of the Company or a Designated Parent or Subsidiary, participation in the Plan shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the
Company or a Designated Parent or Subsidiary, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of
compensation. The Plan is not a “Retirement Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended. 
  

25. EFFECT OF PLAN. The provisions of the Plan shall, in accordance with its terms, be binding upon, and inure to the benefit of, all successors of
each Participant, including, without limitation, such Participant’s estate and the executors, administrators or trustees thereof, heirs and legatees, and any receiver, trustee in bankruptcy or representative of creditors of such Participant.

  
 26. GOVERNING LAW. The Plan is to be construed in accordance
with and governed by the internal laws of the State of Maryland without giving effect to any choice of law rule that 

  

 11 








 
would cause the application of the laws of any jurisdiction other than the internal laws of the State of Maryland to the rights and duties of the parties,
except to the extent the internal laws of the State of Maryland are superseded by the laws of the United States. Should any provision of the Plan be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless
remain effective and shall remain enforceable. 
  
 27. VENUE AND
WAIVER OF JURY TRIAL. The Company and the Participant, or their respective successors (the “parties”) agree that any suit, action, or proceeding arising out of or relating to the Plan shall be brought in the United States District Court
for the District of Maryland (or should such court lack jurisdiction to hear such action, suit or proceeding, in a Maryland state court in the County of Howard) and that the parties shall submit to the jurisdiction of such court. The parties
irrevocably waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A

	5.	PAYROLL DEDUCTION AUTHORIZATION/DIRECT PAYMENT. I hereby authorize payroll deductions from my Compensation during the Purchase Interval in either (a) the percentage specified below
OR (b) the whole dollar amount specified below (payroll deductions may not exceed 10% of Compensation nor the limitation under Section 423(b)(8) of the Code and the regulations thereunder):

	(whole dollars only)	  	$                    

  
 Alternatively or in
addition to the payroll deductions authorized above, I hereby submit the following amount as a direct payment to my account to be used to purchase shares of the Company’s Common Stock in accordance with this Subscription Agreement and the ESPP:

  
 $                     
  
 The total of payroll deductions authorized above and the direct payment submitted herewith (if any) may not exceed 10% of Compensation nor the limitation
under Section 423(b)(8) of the Code and the regulations thereunder. Any direct payments in excess of 10% of Compensation or the limitation under Section 423(b)(8) of the Code shall be returned to me. 
  
 I understand that the Company is not obligated to segregate my payroll
deductions and direct payments (if any) or hold them exclusively for my benefit. 
  

	6.	ESPP ACCOUNTS AND PURCHASE PRICE. I understand that all payroll deductions and direct payments (if any) will be credited to my account under the ESPP. No interest will be credited
on funds held in the account at any time including any refund of the account caused by withdrawal from the ESPP. All payroll deductions and direct payments (if any) shall be accumulated for the purchase of Company Common Stock at the applicable
Purchase Price determined in accordance with the ESPP. 

  

	7.	WITHDRAWAL AND CHANGES IN PAYROLL DEDUCTION. I understand that I may discontinue my participation with respect to a particular Purchase Interval at any time prior to the applicable
Purchase Date as provided in Section 10 of the ESPP, but if I do not withdraw from the ESPP, any accumulated payroll deductions and prior direct payments will be applied automatically to purchase Company Common Stock. I may increase or decrease the
rate of my payroll deductions on only one occasion during any Purchase Interval by completing and timely filing a Change of Status or Direct Payment Notice. Any increase or decrease will be effective for the first full payroll period commencing no
fewer than ten (10) business days following the Company’s receipt of the Change of Status or Direct Payment Notice. 

  

	8.	PERPETUAL SUBSCRIPTION. I understand that this Subscription Agreement shall remain in effect for successive Purchase Intervals until I withdraw from participation in a particular
Purchase Interval, or termination of the ESPP.

	9.	TAXES. I have reviewed the ESPP prospectus discussion of the federal tax consequences of participation in the ESPP and consulted with tax consultants as I deemed advisable prior to
my participation in the ESPP. I hereby agree to notify the Company in writing within thirty (30) days of any disposition (transfer or sale) of any shares purchased under the ESPP if such disposition occurs within two (2) years of the first day of
the Purchase Interval during which the shares were purchased or within one (1) year of the Purchase Date (the date I purchased such shares), and I will make adequate provision to the Company for foreign, federal, state or other tax withholding
obligations, if any, which arise upon the disposition of the shares. In addition, the Company may withhold from my Compensation any amount necessary to meet applicable tax withholding obligations incident to my participation in the ESPP, including
any withholding necessary to make available to the Company any tax deductions or benefits contingent on such withholding. 

  

	10.	ADMINISTRATION AND INTERPRETATION. I agree that any question or dispute regarding the administration or interpretation of the Plan shall be submitted by me or by the Company to the
Administrator. I further agree that the resolution of such question or dispute by the Administrator shall be final and binding on all persons. 

  

	11.	VENUE AND WAIVER OF JURY TRIAL. The Company and I, or our respective successors (the “parties”) agree that any suit, action, or proceeding arising out of or relating to
the Plan shall be brought in the United States District Court for the District of Maryland (or should such court lack jurisdiction to hear such action, suit or proceeding, in a Maryland state court in the County of Howard) and that the parties shall
submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. THE PARTIES ALSO
EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions of this Section 11 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties
that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable.
