authorized representatives and agents with access to material information relating to Unidym’s operations, prospects and financial results. Such information will include any information that is reasonably related to the achievement of the
Earnout Payments, including, without limitation, information relating to the Unidym Revenue. To the extent that any such information is confidential, Arrowhead shall agree to maintain such information in confidence. 

5.02 Restrictions on Open-Market Sales. 
 (a) The Purchaser covenants and agrees that it will not sell any portion of the Shares in an open-market transaction prior to the following schedule: 

 

			
	 Date
	  	Cumulative Portion of Shares Eligible for Sale by
Each Purchaser
	 30 days after Closing
	  	20%
	 90 days after Closing
	  	40%
	 180 days after Closing
	  	60%
	 270 days after Closing
	  	100%

 The Purchaser covenants that any
person or entity acquiring any portion of the Shares in a non-open-market transaction within 270 days from the Closing will, as a condition to any such transfer, agree to the foregoing restrictions on open-market sales. For so long as the foregoing
restrictions are in place on proposed sales by the Purchaser, Park agrees, for himself and his Affiliates, that he and his Affiliates will not sell any shares of Wisepower common stock in excess of the portion of the Shares that are available for
sale by the Purchaser. By way of example only, if the Purchaser is able to sell no more than 100,000 Shares in the aggregate after the first 30 days following Closing, then Park and his affiliates would similarly be able to sell no more than 100,000
shares of Wisepower common stock during that same time. Notwithstanding any of the foregoing, none of the restrictions contained in this Section 5.02 shall apply to those 

  
 6 

 
shares of Company common stock that may result from the exercise of stock options by certain directors of the Company, all as set forth in additional detail in Exhibit B. 

(b) The foregoing restriction under this Section 5.02 shall expire upon the earlier of a Change of Control or Wisepower’s first
public announcement of its intention to consummate a transaction that, if successfully completed, would reasonably be expected to constitute a Change of Control. Wisepower shall provide the Purchaser with prompt written notice (in any event within
24 hours) of the occurrence of either of the foregoing events relating to a Change of Control. For purposes of this Agreement, “Change of Control” shall mean: (i) the sale of all or substantially all of the assets of the
Company on a consolidated basis to an unrelated person or entity, (ii) a merger, reorganization or consolidation pursuant to which the holders of the Company’s outstanding voting power immediately prior to such transaction do not own a
majority of the outstanding voting power of the resulting or successor entity (or its ultimate parent, if applicable) immediately upon completion of such transaction, (iii) the sale of a majority of the voting stock of the Company to a single
person or entity or a group of affiliated persons or entities, or (iv) any other transaction in which the owners of the Company’s outstanding voting power prior to such transaction do not own at least a majority of the outstanding voting
power of the Company or any successor entity immediately upon completion of the transaction. 
 5.03 Notice of
Proposed Sale. 
 (a) From the Closing, the Purchaser shall complete delivery of written notices to
Wisepower (i) on the first day of each calendar month, which notices shall detail the number of Shares held by it as of the last day of the immediately preceding month, and (ii) on the 29th, 89th, 179th and 269th day after Closing, which notices shall detail the number of Shares held by it as of such date. 

(b) If Arrowhead proposes to sell in excess of 100,000 Shares in one or more open-market transactions in any thirty-day period, Arrowhead
shall first give written notice of the proposed sale to Wisepower (a “Notice of Sale”), thereupon Wisepower will have a right of first refusal to purchase the Shares that are proposed to be sold pursuant to the Notice of Sale. To
exercise its right of first refusal under this Section 5.03, Wisepower shall provide Arrowhead with written notice of its irrevocable election to purchase all or any portion of the Shares offered for sale (a “Notice of
Purchase”), which notice must be provided to Arrowhead within 48 hours from the delivery of the Notice of Sale. The price at which the Shares will be purchased and sold pursuant to the Notice of Purchase will be equal to the [volume
weighted average price of Wisepower’s common stock on its principal trading market over the ten trading days following the receipt of the Notice of Purchase by Arrowhead. The purchase and sale of the Shares will close within three Business Days
following this ten-day pricing period.

 4. CONVERSION 
 4.1. Period and Price for Conversion 
 The right of a Bondholder to convert any
Bond into shares of common stock, par value Won 100 (“Common Shares”), of the Company is hereinafter called the “Conversion Right”. Subject to and upon compliance with the provisions of this Condition, the
Conversion Right attaching to any Bond may be exercised at the option of the holder thereof, at any time commencing on January 17, 2012 and ending on the earlier of: (a) repayment in full of the Bond, or (b) January 17, 2014 (the
“Conversion Period”). The number of Common Shares to be issued will be determined by dividing the principal amount of the Bonds deposited for conversion by the Conversion Price of U.S. Dollars $2.00, subject to adjustment as set
forth in Condition 4.3. By way of example only, if the Holder wished to convert $100 of indebtedness hereunder, that would result in the issuance of 50 Common Shares (subject to any appropriate adjustment of the conversion ratio). 

If more than one Bond shall be deposited for conversion at any one time by the same holder and Common Shares to be issued on such
conversion are to be issued to the same person, the number of Common Shares to be issued upon conversion thereof will be calculated on the basis of the aggregate principal amount of the Bonds to be converted. Fractions of Common Shares will not be
issued on conversion but upon conversion of the Bonds, the Company will pay in cash in U.S. dollar a sum equal to such portion of the principal amount of the Bond or Bonds deposited for conversion as corresponds to any amount of Common Shares not
issued as aforesaid. 
 The price at which Common Shares will be issued upon conversion (the “Conversion
Price”) will initially be U.S. Dollars $2.00 per Common Share, but will be subject to adjustment in the manner provided in Condition 4.3. 
 4.2. Procedure for Conversion 
 To exercise the Conversion Right attaching to any
Bond, the holder thereof must complete, execute and deliver at his own expense at the specified office of the Company at which the Bond is deposited for conversion a notice of conversion (a “Conversion Notice”) in duplicate in the
form (for the time being current) set out in Schedule 3 obtainable from the specified office of the Company, together with the relevant Certificate(s). 
 The name of the specified office of the Company is set out at the end of the Form of Certificate of Bonds. 
 As conditions precedent to the conversion, the Bondholder must pay to the Company all stamp, issue, registration or similar taxes and duties (if any) arising on conversion in any jurisdiction in which the
Bond is deposited for conversion or payable in any jurisdiction consequent upon the issue or delivery of Common Shares or any other securities, property or cash to or to the order of a person other than the converting Bondholder, other than any
taxes or duties payable in Korea by the Company in respect of the issue of Common Shares on conversion. Except as aforesaid, the Company will pay the expenses arising on the issue of Common Shares on conversion of the Bonds and all charges in
connection therewith. The date on which any Bond and the Conversion Notice (in duplicate) relating thereto are deposited with the Company or, if later, the date on which all conditions precedent to the conversion thereof are fulfilled is hereinafter
referred to as the “Conversion Date” applicable to such Bonds. A Conversion Notice once deposited may not be withdrawn without the consent in writing of the Company. 

With effect from the Conversion Date, the Company will deem the converting Bondholder to have become the holder of record of the number
of Common Shares to be issued to such Holder upon such conversion (disregarding any retroactive adjustment of the Conversion Price referred to below prior to the time such retroactive adjustment shall have become effective). Thereafter the Company
will, subject to any applicable limitations then imposed by Korean laws and regulations, according to the request made in the relevant Conversion Notice, cause the share transfer agent of the Company as soon as practicable, and in any event within
15 business days after the Conversion Date, either (i) to deliver or cause to be delivered to the order of the person named for that purpose in the relevant Conversion Notice

converting Bondholder or, in cases permitted under Korean law, any other person named for that purpose in the relevant Conversion Notice, together with any other securities, property or cash (including, without limitation, cash payable pursuant to
paragraph 4.1 of this Condition) required to be delivered upon conversion and such assignments and other documents (if any) as may be required by law to effect the transfer thereof, or (ii) to register Korea Securities Depository (or its

 Any
dividend on the Common Shares issued upon conversion of a Bond or Bonds in respect of the Dividend Accrual Period during which the relevant Conversion Date falls will be paid with respect to the full Dividend Accrual Period on the basis that the
conversion took effect immediately before the beginning of such Dividend Accrual Period. No payment or adjustment will be made on conversion for any interest accrued on converted Bonds since the Interest Payment Date last preceding the relevant
Conversion Date. The Common Shares issued upon conversion of the Bonds will in all other respects rank pari passu with the Common Shares in issue on the relevant Conversion Date (except for any right the record date for which precedes such
Conversion Date and any other right excluded by mandatory provisions of applicable law). A “Dividend Accrual Period” means an annual period ending on December 31 in any year.

Consolidation or Reclassification of Shares. 
 If the Company shall make a free distribution of Shares, sub-divide any of its outstanding
Shares, consolidate any of its outstanding Shares into a smaller number of Shares, or re-classify any of its Shares into other securities of the Company, then the following provisions shall apply: 

(1) Adjustment 

the Conversion Price shall be appropriately adjusted so that the holder of any Bond, the Conversion Date in respect of which occurs after
the coming into effect of the adjustment described in this Condition 4.3.1, shall be entitled to receive the number of Common Shares and/or other securities of the Company which he would have held or have been entitled to receive after the happening
of any of the events described above had such Bond been converted immediately prior to the happening of such event (or, if the Company has fixed a prior Record Date for the determination of shareholders entitled to receive any such free distribution
or Shares or other securities issued upon any such sub-division, consolidation or re-classification, immediately prior to such Record Date), but without prejudice to the effect of any other adjustment to the Conversion Price made with effect from
the date of the happening of such event (or such Record Date) or any time thereafter; and 
 (2) Effective Date of Adjustment

 an adjustment made pursuant to this Condition 4.3.1 shall become effective immediately on the relevant event referred to
above becoming effective or, if a Record Date is fixed therefor, immediately after such Record Date; provided that in case where the relevant event referred to above, under applicable Korean Law, requires to be approved by a general meeting of
shareholders of the Company or a meeting of the Board of Directors of the Company before being legally made, and which is so approved after the Record Date fixed for the determination of shareholders entitled to receive such distribution, such

a preference in respect of dividends for this purpose) or of amounts payable in the event of any voluntary or involuntary liquidation or winding-up of the Company;

adjustment of the Conversion Price in respect of such dividend or free distribution shall be made under Condition 4.3.1 or 4.3.2, but in lieu thereof an adjustment shall be made under Condition 4.3.4, 4.3.5, 4.3.6, 4.3.8, 4.3.9 or 4.3.10 below (as

or purchase price; and

receivable in a currency other than Won at a time when the Current Market Price per Share is stated in Won, then the value of such consideration shall (in any case where there is a fixed rate of exchange between the Won and the relevant currency for
the purposes of the issue of the Shares, the conversion or exchange of such securities or the exercise of such rights or warrants) be converted into Won for the purposes of this Condition 4.3.12 at such fixed rate of exchange and shall (in all other
cases) be converted into Won at the market average exchange rate between Won and the relevant currency (being announcements for the cross rate through dollars if no direct exchange rate is announced) announced by Korea Financial
Telecommunications & Clearings Institute for buying and selling units of the relevant currency against Won on the date as of which the said consideration is required to be calculated as aforesaid. If the Current Market Price per Share is

already incorporates an adjustment made (or taken or to be taken into account pursuant to the proviso to Condition 4.3.14 below) to reflect an issue of Shares or of securities convertible into or exchangeable for Shares or of rights or warrants to
subscribe for or purchase Shares or securities, to the extent that the number of such Shares taken into account for the purposes of calculating such adjustment exceeds the number of such Shares in issue at the time relevant for ascertaining the
number of outstanding Shares for the purposes of computing the later adjustment, such Shares shall be deemed to be outstanding for the purpose of making such computation.

the receipt by the Bondholders of the amounts which would otherwise have been receivable (in the absence of such deduction or withholdings) except that no such additional amount shall be payable in respect of any Bond beyond the total indebtedness
evidenced thereunder:

such Bond by reason of his being connected with Korea (or any political subdivision thereof) otherwise than merely by holding the Bond or by the receipt of principal, premium (if any) or interest in respect of any Bond; or 

(2)(if surrender of the relevant Certificate is a condition to payment) where the Certificate in respect of such Bond is surrendered more

it is in fact the case, such last day to be a business day. 
 For this purpose the “relevant date” in relation to any payment
means the due date for that payment thereof. 
 Reference in these Conditions to principal or premium or interest shall be deemed also to refer
to any additional amounts which may be payable under this Condition.

issue give rise to any adjustment to the Conversion Price pursuant to Condition 4.3; or

notice shall also state the Conversion Price in effect at the time such notice is required to be given and the Conversion Price which will result after giving effect to such event or, if such adjusted Conversion Price is not then determinable, the
fact that an adjustment in the Conversion Price may result. The Company will also ensure that, without prejudice to the provisions of Condition 9.4, if, after giving effect to the event covered by any such notice and to any adjustment in the
