	2)	Type of Stock Options. The options granted hereunder are non-qualified stock options and do not qualify as incentive stock options as that term is used in

	October 1, 2002	  	A cumulative total of 80% of the Option Shares
	October 1, 2003	  	A cumulative total of 100% of the Option Shares

 In the event of a public offering by the Company of its Common Stock or a sale by the Company of
all or substantially all of the assets of the Company, all then-unvested Option Shares shall immediately become vested and exercisable. 
 Vested options may be exercised by Optionee at any time and from time to time prior to the termination of the options as provided below in Section 5; provided, however, that vested options may be exercised from time to
time only in minimum increments equal to the lesser of (i) the then unexercised vested options, or (ii) 25% of the original number of Option Shares 
 covered by this Agreement, adjusted as provided below in Section 6. 
 The options granted hereunder
shall not be transferable other than by Will or the laws of descent and distribution. 
 During Optionee’s lifetime, the options
granted hereunder may only be exercised by Optionee. 
  

	4)	Method of Exercise of Options. 

  

	 	a)	The options granted hereunder shall be exercised by written notice delivered to the President or Secretary of the Company at its principal office specifying the number of Option
Shares to be purchased and accompanied by a certified or cashier’s check payable to the order of the Company for the full purchase price of the Option Shares to be purchased. 

  

	 	b)	The Company may, in its sole discretion, accept other property (including its own shares of stock) in payment for the Option Shares to be purchased. If the exercise of the options
is made in accordance with the provisions of this Agreement, the Company shall, as soon as practicable, deliver to Optionee a certificate or certificates for the Option Shares so purchased.

	 	a)	Ten (10) years from the date of this Agreement;

Section 5(a), above, or the one (1) year period set forth in Section 5(b), above, is limited to that number of options which were exercisable on the date of the termination of Optionee’s continuous status as an employee or

Optionee’s distributees may exercise Optionee’s right to purchase Option Shares hereunder. 
  

	6)	Adjustments in Outstanding Options. The number of shares of Common Stock which may be acquired under this Agreement, as well as the price per share of Common Stock
covered by this Agreement, shall be proportionately and equitably adjusted when, as and to the extent determined by the Board.

taken all action required for the purchase of shares upon proper exercise of this Option. 

  

	9)	No Increased Rights as an Employee or Director. Nothing in this Agreement shall confer upon Optionee any right to continue in the employ of, or as a director of, the

	 	iii)	The entire legal and beneficial interest of the option rights and Option Shares being purchased are, and will be, held for Optionee’s account only, and neither in whole or in

 STOCK
OPTION AGREEMENT - ERIC HAFTER 
  

 - 2 - 

	 	i)	Prior to the date of this Agreement Optionee has discussed the Company and its plans, operations and financial condition with the Company’s officers and has received all such
information as Optionee has deemed necessary and appropriate to enable Optionee to evaluate the financial risk inherent in this Agreement and Optionee has received satisfactory and complete information concerning the business and financial condition
of the Company in response to all inquiries in respect thereof. 

  

	 	ii)	Prior to the exercise of any option rights hereunder, Optionee will have discussed the Company and its plans, operations and financial condition with the Company’s officers and
will have received all such information as Optionee deems necessary and appropriate to enable Optionee to evaluate the financial risk inherent in making an investment in the Option Shares, and Optionee will have received satisfactory and complete
information concerning the business and financial condition of the Company in response to all inquiries in respect thereof. 

  

	e)	Economic Risk. Optionee realizes that the purchase of Option Shares will be a highly speculative investment and involves a high degree of risk, and Optionee will not
acquire any Option Shares unless Optionee is able, without impairing his or her financial condition, to hold the Option Shares for an indefinite period of time and to suffer a complete loss on Optionee’s investment. 

  

	f)	Restricted Securities. Optionee understands and acknowledges that: 

  

	 	i)	The sale of the Option Shares will not have been registered under the Securities Act, and the Option Shares must be held indefinitely unless subsequently registered under the
Securities Act or an exemption from such registration is available (such as Rule 144 or the resale provisions of Rule 701 under the Securities Act) and the Company is under no obligation to register the Option Shares; 

  

	 	ii)	The share certificate representing the Option Shares will be stamped with the legends specified in this Agreement or under applicable law; and 

  

	 	iii)	The Company will make a notation in its records of the aforementioned restrictions on transfer and legends. 

  

	g)	Disposition under the Securities Act. Optionee understands that the Option Shares will be restricted securities within the meaning of Rule 144 promulgated under the
Securities Act; that the exemption from registration under Rule 144 will not be available in any event for at least one (1) year from the date of purchase of the Option Shares (unless Rule 701 promulgated under the Securities Act is available),
and even then will not be available unless (i) a public trading market then exists for the Common Stock of the Company, (ii) adequate information concerning the Company is then available to the public, and (iii) other terms and
conditions of Rule 144 are complied with; and that any sale of the Option Shares may be made only in limited amounts in accordance with such terms and conditions. Optionee further understands that the resale provisions of Rule 701, if available,
will not apply until ninety (90) days after the Company becomes subject to the reporting obligations under the Securities Exchange Act of 1934 (the “Exchange Act”). There can be no assurance that the requirements of Rule 144 or Rule
701 will be met, or that the stock will ever be saleable. 

  

	h)	Further Limitations on Disposition. Without in any way limiting Optionee’s representations set forth above, Optionee further agrees that Optionee shall in no
event make any disposition of all or any portion of the Option Shares unless and until: 

  

	 	i)	The Option Shares proposed to be transferred shall no longer be subject to the restrictions set forth in the Market Standoff Agreement and the Stock Restriction Agreement.

  

	 	ii)	One of the following conditions is satisfied: 

  

	 	(1)	There is then in effect a Registration Statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with said Registration
Statement. 

  

	 	(2)	The resale provisions of Rule 701 or Rule 144 are available in the opinion of counsel to the Company. 

  

	 	(3)	Optionee shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed
disposition; Optionee shall have furnished the Company with an opinion of Optionee’s counsel to the effect that such disposition will not require registration of such Option Shares under the Securities Act; and such opinion of Optionee’s
counsel shall have been concurred with by counsel for the Company and the Company shall have advised Optionee of such concurrence.

	 	ii)	the proposed sale of all or substantially all of the assets of the Company, 

  

	 	iii)	the Board shall notify Optionee as soon as practicable prior to the effective date of such Company Termination Event. 

  

	 	b)	The Board in its discretion may provide for Optionee to have the right to exercise his rights hereunder until fifteen (15) days prior to such Company Termination Event as to

	 	ii)	replace the outstanding Option Shares with equivalent awards which provide substantially equivalent benefits to Optionee as are provided to the shareholders of the Corporation
(after taking into account the existing provisions of this Agreement, including, without limitation, vesting schedules, repurchase rights, exercise prices and the like). 

  

	 	b)	In the event that the surviving entity in the Merger is unwilling to assume the outstanding obligations of the Company under this Agreement or replace the outstanding Option Shares

 THIS STOCK RESTRICTION AGREEMENT (“Agreement”) is entered

as follows: 
 RECITALS 
  

	A.	The Company has granted Optionee options or rights (in either case, the “Rights”) to purchase shares of the Common Stock of the Company pursuant to one or more Stock
Option Agreements or a Restricted Stock Purchase Agreements (in either case, the “Stock Agreements”). 

  

	B.	As used herein, the term “Shares” means (1) any shares of the Common Stock of the Company issued on exercise of any of the Stock Agreements, and (2) any other
stock or securities issued or distributed by the Company on account of any such shares, whether by reason of stock dividend, stock split, recapitalization, reorganization, exchange of shares or otherwise. 

  

	C.	As a condition for the grant of the Rights, the Company has required that Optionee execute this Agreement so as to provide (1) an option in favor of the Company to repurchase
any of the Shares in the event that Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company) is terminated for any reason, and (2) to give the Company a right of first refusal in the case of any
transfer of Shares. 

 AGREEMENT 
 NOW, THEREFORE, the Company and Optionee recite and agree as follows: 
  

	1)	Repurchase Right. The Company shall have, and Optionee hereby grants to the Company, the option to repurchase part or all of the Shares on the terms set forth below:

  

	 	a)	In the event that Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company) is terminated for any reason (whether with or without
cause, or by reason of Optionee’s death, disability or otherwise) the Company shall have an option to repurchase the Shares on the terms set forth below. 

  

	 	b)	The Company may exercise its repurchase option rights under this Agreement by written notice of exercise to Optionee (or Optionee’s Representative) given at any time prior to

	 	f)	The term “Optionee’s Representative” means, in the event of Optionee’s death, the executor or executrix under Optionee’s Will, the administrator of

POWERLIGHT CORPORATION (the “Company”), a California corporation. 
 RECITALS 
  

	A.	Optionee is an officer or director of the Company. 

  

	B.	The Company considers it desirable and in its best interests that Optionee be given an added incentive to advance the interests of the Company in the form of options to purchase

	2)	Type of Stock Options. The options granted hereunder are non-qualified stock options and do not qualify as incentive stock options as that term is used in
Section 422 of the Internal Revenue Code.

	October 1, 2002	  	A cumulative total of 80% of the Option Shares
	October 1, 2003	  	A cumulative total of 100% of the Option Shares

 In the event of a public offering by the Company of its Common Stock or a sale by the Company of
all or substantially all of the assets of the Company, all then-unvested Option Shares shall immediately become vested and exercisable. 
 Vested options may be exercised by Optionee at any time and from time to time prior to the termination of the options as provided below in Section 5; provided, however, that vested options may be exercised from time to
time only in minimum increments equal to the lesser of (i) the then unexercised vested options, or (ii) 25% of the original number of Option Shares covered by this Agreement, adjusted as provided below in Section 6. 
 The options granted hereunder shall not be transferable other than by Will or the laws of descent and distribution. During Optionee’s lifetime,
the options granted hereunder may only be exercised by Optionee. 
  

	4)	Method of Exercise of Options. 

  

	 	a)	The options granted hereunder shall be exercised by written notice delivered to the President or Secretary of the Company at its principal office specifying the number of Option

	 	b)	The Company may, in its sole discretion, accept other property (including its own shares of stock) in payment for the Option Shares to be purchased. If the exercise of the options
is made in accordance with the provisions of this Agreement, the Company shall, as soon as practicable, deliver to Optionee a certificate or certificates for the Option Shares so purchased.

	 	a)	Ten (10) years from the date of this Agreement;

	 	c)	The expiration of one (1) year from the date on which Optionee’s continuous status as an employee or director of the Company is terminated by reason of Optionee’s

exercised during the three (3) month period set forth in Section 5(b), above, or the one (1) year period set forth in Section 5(c), above, is limited to that number of options which were exercisable on the date of the termination

 STOCK
OPTION AGREEMENT - GARY WAYNE 
  

 - 2 -

information as Optionee has deemed necessary and appropriate to enable Optionee to evaluate the financial risk inherent in this Agreement and Optionee has received satisfactory and complete information concerning the business and financial condition
of the Company in response to all inquiries in respect thereof. 

  

	 	ii)	Prior to the exercise of any option rights hereunder, Optionee will have discussed the Company and its plans, operations and financial condition with the Company’s officers and

information concerning the business and financial condition of the Company in response to all inquiries in respect thereof. 

  

	e)	Economic Risk. Optionee realizes that the purchase of Option Shares will be a highly speculative investment and involves a high degree of risk, and Optionee will not
acquire any Option Shares unless Optionee is able, without impairing his or her financial condition, to hold the Option Shares for an indefinite period of time and to suffer a complete loss on Optionee’s investment. 

  

	f)	Restricted Securities. Optionee understands and acknowledges that: 

  

	 	i)	The sale of the Option Shares will not have been registered under the Securities Act, and the Option Shares must be held indefinitely unless subsequently registered under the
Securities Act or an exemption from such registration is available (such as Rule 144 or the resale provisions of Rule 701 under the Securities Act) and the Company is under no obligation to register the Option Shares; 

  

	 	ii)	The share certificate representing the Option Shares will be stamped with the legends specified in this Agreement or under applicable law; and 

  

	 	iii)	The Company will make a notation in its records of the aforementioned restrictions on transfer and legends.

Securities Act; that the exemption from registration under Rule 144 will not be available in any event for at least one (1) year from the date of purchase of the Option Shares (unless Rule 701 promulgated under the Securities Act is available),
and even then will not be available unless (i) a public trading market then exists for the Common Stock of the Company, (ii) adequate information concerning the Company is then available to the public, and (iii) other terms and
conditions of Rule 144 are complied with; and that any sale of the Option Shares may be made only in limited amounts in accordance with such terms and conditions. Optionee further understands that the resale provisions of Rule 701, if available,
will not apply until ninety (90) days after the Company becomes subject to the reporting obligations under the Securities Exchange Act of 1934 (the “Exchange Act”). There can be no assurance that the requirements of Rule 144 or Rule
701 will be met, or that the stock will ever be saleable. 

  

	h)	Further Limitations on Disposition. Without in any way limiting Optionee’s representations set forth above, Optionee further agrees that Optionee shall in no
event make any disposition of all or any portion of the Option Shares unless and until: 

  

	 	i)	The Option Shares proposed to be transferred shall no longer be subject to the restrictions set forth in the Market Standoff Agreement and the Stock Restriction Agreement.

  

	 	ii)	One of the following conditions is satisfied: 

  

	 	(1)	There is then in effect a Registration Statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with said Registration
Statement. 

  

	 	(2)	The resale provisions of Rule 701 or Rule 144 are available in the opinion of counsel to the Company. 

  

	 	(3)	Optionee shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed
disposition; Optionee shall have furnished the Company with an opinion of Optionee’s counsel to the effect that such disposition will not require registration of such Option Shares under the Securities Act; and such opinion of Optionee’s
counsel shall have been concurred with by counsel for the Company and the Company shall have advised Optionee of such concurrence.

	 	ii)	the proposed sale of all or substantially all of the assets of the Company, 

  

	 	iii)	the Board shall notify Optionee as soon as practicable prior to the effective date of such Company Termination Event.

 THIS STOCK RESTRICTION AGREEMENT (“Agreement”) is entered
into effective as of October 23, 2000, by and between (a) POWERLIGHT CORPORATION (the “Company”), a California corporation, and (b) GARY WAYNE (“Optionee”). The Company and Optionee recite and agree
as follows: 
 RECITALS 
  

	A.	The Company has granted Optionee options or rights (in either case, the “Rights”) to purchase shares of the Common Stock of the Company pursuant to one or more Stock
Option Agreements or a Restricted Stock Purchase Agreements (in either case, the “Stock Agreements”). 

  

	B.	As used herein, the term “Shares” means (1) any shares of the Common Stock of the Company issued on exercise of any of the Stock Agreements, and (2) any other
stock or securities issued or distributed by the Company on account of any such shares, whether by reason of stock dividend, stock split, recapitalization, reorganization, exchange of shares or otherwise. 

  

	C.	As a condition for the grant of the Rights, the Company has required that Optionee execute this Agreement so as to provide (1) an option in favor of the Company to repurchase
any of the Shares in the event that Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company) is terminated for any reason, and (2) to give the Company a right of first refusal in the case of any
transfer of Shares. 

 AGREEMENT 
 NOW, THEREFORE, the Company and Optionee recite and agree as follows: 
  

	1)	Repurchase Right. The Company shall have, and Optionee hereby grants to the Company, the option to repurchase part or all of the Shares on the terms set forth below:

  

	 	a)	In the event that Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company) is terminated for any reason (whether with or without
cause, or by reason of Optionee’s death, disability or otherwise) the Company shall have an option to repurchase the Shares on the terms set forth below. 

  

	 	b)	The Company may exercise its repurchase option rights under this Agreement by written notice of exercise to Optionee (or Optionee’s Representative) given at any time prior to
the later of (1) the date which is sixty (60) days after the date of the termination of Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company), or (2) the date which is sixty
(60) days after the expiration of any and all remaining exercise or purchase rights under the Stock Agreements. 

  

	 	c)	The Company’s written notice of exercise shall (i) make reference to this Agreement, (ii) specify the number of Shares being repurchased and (iii) specify the
Company’s good faith determination of the repurchase price for the Shares to be repurchased.

	 	ii)	the aggregate fair market value of the Shares being repurchased as of the date of the termination of Optionee’s employment with or consultancy to the Company (or any Parent or
Subsidiary of the Company), determined by agreement of the parties or, in the absence of any such agreement, by arbitration as provided below. 

 The parties acknowledge the difficulty and uncertainty in determining the fair market value of shares of stock of a private company such as the Company. Accordingly, for purposes of ease of administration and the
elimination of uncertainty, the parties agree that, for purposes of this Agreement, the per-share fair market value of the Company’s Common Stock shall be determined by dividing: 
  

	 	(A)	the One Hundred and Seventy-Five Percent (175%) of the Company’s net book value as reflected on the Company’s financial statements for the month ended immediately
prior to the date that Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company) is terminated for any reason (whether with or without cause, or by reason of Optionee’s death, disability or
otherwise), and

Common Stock issuable upon exercise of issued and outstanding options, whether or not then vested and exercisable, all shares of Common Stock issuable upon conversion of issued and outstanding Preferred Stock or other convertible securities of the
Company). 

  

	 	e)	The closing for the Company’s repurchase of Shares shall take place within ten (10) days of the date on which the repurchase price is determined by the Company. The
repurchase price shall be paid by the Company in cash (or by cancellation of any purchase money indebtedness of Optionee owing to the Company in connection with the purchase of any of the Shares) at the closing. 

  

	 	f)	The term “Optionee’s Representative” means, in the event of Optionee’s death, the executor or executrix under Optionee’s Will, the administrator of
