Amended and Restated 2006 Equity Incentive Plan



 Exhibit 4.3 
 2006 EQUITY INCENTIVE PLAN 
 OF 

IMMUNOCELLULAR THERAPEUTICS, LTD. 
 (As Amended and Restated as of September 27, 2010) 
  

	1.	PURPOSES OF THE PLAN 

 The purposes of the 2006 Equity Incentive Plan (“Plan”) of IMMUNOCELLULAR THERAPEUTICS, LTD., a Delaware corporation formerly known as Patco Industries, Ltd. and Optical Molecular Imaging, Inc.
(the “Company”), are to: 
 1.1 Encourage selected employees, directors, consultants and advisers to improve
operations and increase the profitability of the Company; 
 1.2 Encourage selected employees, directors, consultants and
advisers to accept or continue employment or association with the Company or its Affiliates; and 
 1.3 Increase the interest of
selected employees, directors, consultants and advisers in the Company’s welfare through participation in the growth in value of the common stock of the Company, par value $.001 per share (the “Common Stock”). The Company intends to
effect a .00434-for-1 reverse stock split of the Common Stock shortly after the adoption of this Plan. Accordingly, all references in this Plan to the number of shares of Common Stock for any purpose assume that the .4032258-for-1 reverse stock
split has been effected and represent shares after such stock split. 
  

	2.	TYPES OF AWARDS; ELIGIBLE PERSONS 

 2.1 The Administrator (as defined below) may, from time to time, take the following action, separately or in combination, under the Plan: (i) grant “incentive stock options”
(“ISOs”) intended to satisfy the requirements of Section 422 of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (the “Code”); (ii) grant “non-qualified options” (“NQOs,”
and together with ISOs, “Options”); (iii) grant or sell Common Stock subject to restrictions (“restricted stock”) and (iv) grant stock appreciation rights (in general, the right to receive the excess of the fair market
value of Common Stock on the exercise date over its fair market value on the grant date (“SARs”)), either in tandem with Options or as separate and independent grants. Any such awards may be made to employees, including employees who are
officers or directors, and to individuals described in Section 1 of this Plan who the Administrator believes have made or will make a contribution to the Company or any Affiliate (as defined below); provided, however, that only a person who is
an employee of the Company or any Affiliate at the date of the grant of an Option is eligible to receive ISOs under the plan. The term “Affiliate” as used in this Plan means a parent or subsidiary corporation as defined in the applicable
provisions (currently Sections 424(e) and (f), respectively) of the Code. The term “employee” includes an officer or director who is an employee of the Company. The term “consultant” includes persons employed by, or otherwise
affiliated with, a consultant. The term “adviser” includes persons employed by, or otherwise affiliated with, an adviser. 
 2.2 Except as otherwise expressly set forth in this Plan, no right or benefit under this Plan shall be subject in any manner to anticipation, alienation, hypothecation, or charge, and any such attempted
action shall be void. No right or benefit under this Plan shall in any manner be liable for or subject to debts, contracts, liabilities, or torts of any option holder or any other person except as otherwise may be expressly required by applicable
law. 








	3.	STOCK SUBJECT TO THIS PLAN; MAXIMUM NUMBER OF GRANTS 

 Subject to the provisions of Sections 6.1.1 and 8.2 of this Plan, the total number of shares of Common Stock which may be offered, or issued as restricted stock or on the exercise of Options or SARs under
the Plan shall not exceed six million (6,000,000) shares of Common Stock. The shares subject to an Option or SAR granted under the Plan which expire, terminate or are cancelled unexercised shall become available again for grants under
this Plan. If shares of restricted stock awarded under the Plan are forfeited to the Company or repurchased by the Company, the number of shares forfeited or repurchased shall again be available under the Plan. Where the exercise price of an Option
is paid by means of the optionee’s surrender of previously owned shares of Common Stock or the Company’s withholding of shares otherwise issuable upon exercise of the Option as may be permitted herein, only the net number of shares issued
and which remain outstanding in connection with such exercise shall be deemed “issued” and no longer available for issuance under this Plan. No eligible person shall be granted Options or other awards during any twelve-month period
covering more than seven hundred twenty-five thousand (725,000) shares. 
  

	4.	ADMINISTRATION 


4.1 This Plan shall be administered by the Board of Directors of the Company (the “Board”) or by a committee (the
“Committee”) to which administration of this Plan, or of part of this Plan, is delegated by the Board (in either case, the “Administrator”). The Board shall appoint and remove members of the Committee in its discretion in
accordance with applicable laws. At the Board’s discretion, the Committee may be comprised solely of “non-employee directors” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), or “outside directors” within the meaning of Section 162(m) of the Code. The Administrator may delegate non-discretionary administrative duties to such employees of the Company as the Administrator deems proper and the
Board, in its absolute discretion, may at any time and from time to time exercise any and all rights and duties of the Administrator under this Plan. 
 4.2 Subject to the other provisions of this Plan, the Administrator shall have the authority, in its discretion: (i) to grant Options and SARs and grant or sell restricted stock; (ii) to
determine the fair market value of the Common Stock subject to Options or other awards; (iii) to determine the exercise price of Options granted, the economic terms of SARs granted, or the offering price of restricted stock; (iv) to
determine the persons to whom, and the time or times at which, Options or SARs shall be granted or restricted stock granted or sold, and the number of shares subject to each Option or SAR or the number of shares of restricted stock granted or sold;
(v) to construe and interpret the terms and provisions of this Plan, of any applicable agreement and all Options and SARs granted under this Plan, and of any restricted stock award under this Plan; (vi) to prescribe, amend, and rescind
rules and regulations relating to this Plan; (vii) to determine the terms and provisions of each Option and SAR granted and award of restricted stock (which need not be identical), including but not limited to, the time or times at which
Options and SARs shall be exercisable or the time at which the restrictions on restricted stock shall lapse; (viii) with the consent of the grantee, to rescind any award or exercise of an Option or SAR and to modify or amend the terms of any
Option, SAR or restricted stock; (ix) to reduce the exercise price of any Option, the base value from which appreciation is to be determined with respect to an SAR or the purchase price of restricted stock, provided that any such reduction
shall not be less than provided with Sections 6.2.1 and 6.3.1; (x) to accelerate or defer (with the consent of the grantee) the exercise date of any Option or SAR or the date on which the restrictions on restricted stock lapse; (xi) to
issue shares of restricted stock to an optionee in connection with the accelerated exercise of an Option by such optionee; (xii) to authorize any person to execute on behalf of the Company any instrument evidencing the grant of an Option. SAR
or award of restricted stock; (xiii) to determine the duration and purposes of leaves of absence which may be granted to participants without constituting a termination of their employment for the purposes of the Plan; and (xiv) to make
all other determinations deemed necessary or advisable for the administration of this Plan, any applicable agreement, Option, SAR or award of restricted stock. 
 4.3 All questions of interpretation, implementation, and application of this Plan or any agreement or Option, SAR or award of restricted stock shall be determined by the Administrator, which determination
shall be final and binding on all persons. 
  

	5.	GRANTING OF OPTIONS AND SARS; AGREEMENTS 

 5.1 No Options or SARs shall be granted under this Plan after ten (10) years from the date of adoption of this Plan by the Board. No SARs shall be granted under the Plan unless and until the common
stock of the Company is publicly traded. 







 5.2 Each Option and SAR shall be evidenced by a written agreement, in form satisfactory to
the Administrator, executed by the Company and the person to whom such grant is made. In the event of a conflict between the terms or conditions of an agreement and the terms and conditions of this Plan, the terms and conditions of this Plan shall
govern. 
 5.3 Each agreement shall specify whether the Option it evidences is an NQO or an ISO, provided, however, all Options
granted under this Plan to non-employee directors, consultants and advisers of the Company are intended to be NQOs. 
 5.4
Subject to Section 6.3.3 with respect to ISOs, the Administrator may approve the grant of Options or SARs under this Plan to persons who are expected to become employees, directors, consultants or advisers of the Company, but are not employees,
directors, consultants or advisers at the date of approval. 
  

	6.	TERMS AND CONDITIONS OF OPTIONS AND SARS 

 Each Option and SAR granted under this Plan shall be subject to the terms and conditions set forth in Section 6.1. NQOs and SARs shall also be subject to the terms and conditions set forth in
Section 6.2, but not those set forth in Section 6.3. ISOs shall also be subject to the terms and conditions set forth in Section 6.3, but not those set forth in Section 6.2. SARs shall be subject to the terms and conditions of
Section 6.4. 
 6.1 Terms and Conditions to Which All Options and SARs Are Subject. All Options and SARs granted
under this Plan shall be subject to the following terms and conditions: 
 6.1.1 Changes in Capital Structure. Subject to
Section 6.1.2, if the stock of the Company is changed by reason of a stock split, reverse stock split, stock dividend, recapitalization, combination or reclassification, or if the Company effects a spin-off of the Company’s subsidiary,
appropriate adjustments shall be made by the Administrator, in its sole discretion, in (a) the number and class of shares of stock subject to this Plan and each Option and SAR outstanding under this Plan, and (b) the exercise price of each
outstanding Option; provided, that the Company shall not be required to issue fractional shares as a result of any such adjustments. Any adjustment, however, in an outstanding Option shall be made without change in the total price applicable to the
unexercised portion of the Option but with a corresponding adjustment in the price for each share covered by the unexercised portion of the Option. Adjustments under this Section 6.1.1 shall be made by the Administrator, whose determination as
to the nature of the adjustments that shall be made, and the extent thereof, shall be final, binding, and conclusive. If an adjustment under this Section 6.1.1 would result in a fractional share interest under an option or any installment, the
Administrator’s decision as to inclusion or exclusion of that fractional share interest shall be final, but no fractional shares of stock shall be issued under the Plan on account of any such adjustment. 

6.1.2 Corporate Transactions. Except as otherwise provided in the applicable agreement, in the event of a Corporate Transaction
(as defined below), the Administrator shall notify each holder of an Option or SAR at least thirty (30) days prior thereto or as soon as may be practicable. To the extent not then exercised all Options and SARs shall terminate immediately prior
to the consummation of such Corporate Transaction unless the Administrator determines otherwise in its sole discretion; provided. however, that the Administrator, in its sole discretion, may (i) permit exercise of any Options or SARs prior to
their termination, even if such Options or SARs would not otherwise have been exercisable, and/or (ii) provide that all or certain of the outstanding Options and SARs shall be assumed or an equivalent Option or SAR substituted by an applicable
successor corporation or entity or any Affiliate of the successor corporation or entity. A “Corporate Transaction” means (i) a liquidation or dissolution of the Company; (ii) a merger or consolidation of the Company with or into
another corporation or entity (other than a merger with a wholly-owned subsidiary); (iii) a sale of all or substantially all of the assets of the Company; or (iv) a purchase or other acquisition of more than 50% of the outstanding stock of
the Company by one person or by more than one person acting in concert. 







 6.1.3 Time of Option or SAR Exercise. Subject to Section 5 and
Section 6.3.4, an Option or SAR granted under the Plan shall be exercisable (a) immediately as of the effective date of the of the applicable agreement or (b) in accordance with a schedule or performance criteria as may be set by the
Administrator and specified in the applicable agreement. However, in no case may an Option or SAR be exercisable until a written agreement in form and substance satisfactory to the Company is executed by the Company and the grantee. 

6.1.4 Grant Date. The date of grant of an Option or SAR under the Plan shall be the effective date of the applicable agreement.

 6.1.5 Non-Transferability of Rights. Except with the express written approval of the Administrator, which approval the
Administrator is authorized to give only with respect to NQOs and SARs, no Option or SAR granted under this Plan shall be assignable or otherwise transferable by the grantee except by will or by the laws of descent and distribution. During the life
of the grantee, an Option or SAR shall be exercisable only by the grantee. 
 6.1.6 Payment. Except as provided below,
payment in full, in cash, shall be made for all stock purchased at the time written notice of exercise of an Option is given to the Company and the proceeds of any payment shall be considered general funds of the Company. The Administrator, in the
exercise of its absolute discretion after considering any tax, accounting and financial consequences, may authorize any one or more of the following additional methods of payment: 

(a) Subject to the Sarbanes-Oxley Act of 2002, acceptance of the optionee’s full recourse promissory note for all or part of the
Option price, payable on such terms and bearing such interest rate as determined by the Administrator (but in no event less than the minimum interest rate specified under the Code at which no additional interest or original issue discount would be
imputed), which promissory note may be either secured or unsecured in such manner as the Administrator shall approve (including, without limitation, by a security interest in the shares of the Company); 

(b) Subject to the discretion of the Administrator and the terms of the stock option agreement granting the Option, delivery by the
optionee of shares of Common Stock already owned by the optionee for all or part of the Option price, provided the fair market value (determined as set forth in Section 6.1.9) of such shares of Common Stock is equal on the date of exercise to
the Option price, or such portion thereof as the optionee is authorized to pay by delivery of such stock; 
 (c) Subject to the
discretion of the Administrator, through the surrender of shares of Common Stock then issuable upon exercise of the Option, provided the fair market value (determined as set forth in Section 6.1.9) of such shares of Common Stock is equal on the
date of exercise to the Option price, or such portion thereof as the optionee is authorized to pay by surrender of such stock; and 
 (d) By means of so-called cashless exercises as permitted under applicable rules and regulations of the Securities and Exchange Commission and the Federal Reserve Board. 

6.1.7 Withholding and Employment Taxes. At the time of exercise and as a condition thereto, or at such other time as the amount of
such obligation becomes determinable, the grantee of an Option or SAR shall remit to the Company in cash all applicable federal and state withholding and employment taxes. Such obligation to remit may be satisfied, if authorized by the Administrator
in its sole discretion, after considering any tax, accounting and financial consequences, by the holder’s (i) delivery of a promissory note in the required amount on such terms as the Administrator deems appropriate, (ii) tendering to
the Company previously owned shares of Common Stock or other securities of the Company with a fair market value equal to the required amount, or (iii) agreeing to have shares of Common Stock (with a fair market value equal to the required
amount), which are acquired upon exercise of the Option or SAR, withheld by the Company. 
 6.1.8 Other Provisions. Each
Option and SAR granted under this Plan may contain such other terms, provisions, and conditions not inconsistent with this Plan as may be determined by the Administrator, and each ISO granted under this Plan shall include such provisions and
conditions as are necessary to qualify the Option as an “incentive stock option” within the meaning of Section 422 of the Code. 







 6.1.9 Determination of Value. For purposes of this Plan, the fair market value of
Common Stock or other securities of the Company shall be determined as follows: 
 (a) If the stock of the Company is listed on
a securities exchange or is regularly quoted by a recognized securities dealer, and selling prices are reported, its fair market value shall be the closing price of such stock on the date the value is to be determined, but if selling prices are not
reported, its fair market value shall be the mean between the high bid and low asked prices for such stock on the date the value is to be determined (or if there are no quoted prices for the date of grant, then for the last preceding business day on
which there were quoted prices). 
 (b) In the absence of an established market for the stock, the fair market value thereof
shall be determined in good faith by the Administrator, with reference to the Company’s net worth, prospective earning power, dividend-paying capacity, and other relevant factors, including the goodwill of the Company, the economic outlook in
the Company’s industry, the Company’s position in the industry, the Company’s management, and the values of stock of other corporations in the same or a similar line of business. 

6.1.10 Option and SAR Term. No Option or SAR shall be exercisable more than 10 years after the date of grant, or such lesser
period of time as is set forth in the applicable agreement (the end of the maximum exercise period stated in the agreement is referred to in this Plan as the “Expiration Date”). 

6.2 Terms and Conditions to Which NQOs and SARs Are Subject. Options granted under this Plan which are designated as NQOs and SARs
shall be subject to the following terms and conditions: 
 6.2.1 Exercise Price. The exercise price of an NQO and the
base value of a SAR shall be no less than the fair market value of the Common Stock on the date of grant. 
 6.2.2
Termination of Employment. Except as otherwise provided in the applicable agreement, if for any reason a grantee ceases to be employed by the Company or any of its Affiliates, Options that are NQOs and SARs held at the date of termination (to
the extent then exercisable) may be exercised in whole or in part at any time within ninety (90) days of the date of such termination (but in no event after the Expiration Date). For purposes of this Section 6.2.2, “employment”
includes service as a director, consultant or adviser. For purposes of this Section 6.2.2, a grantee’s employment shall not be deemed to terminate by reason of the grantee’s transfer from the Company to an Affiliate, or vice versa, or
sick leave, military leave or other leave of absence approved by the Administrator, if the period of any such leave does not exceed ninety (90) days or, if longer, if the grantee’s right to reemployment by the Company or any Affiliate is
guaranteed either contractually or by statute. 
 6.3 Terms and Conditions to Which Only ISOs Are Subject. Options
granted under this Plan which are designated as ISOs shall be subject to the following terms and conditions: 
 6.3.1
Exercise Price. The exercise price of an ISO shall not be less than the fair market value (determined in accordance with Section 6.1.9) of the stock covered by the Option at the time the Option is granted. The exercise price of an ISO
granted to any person who owns, directly or by attribution under the Code (currently Section 424(d)), stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any
Affiliate (a “Ten Percent Stockholder”) shall in no event be less than one hundred ten percent (110%) of the fair market value (determined in accordance with Section 6.1.9) of the stock covered by the Option at the time the
Option is granted. 
 6.3.2 Disqualifying Dispositions. If stock acquired by exercise of an ISO granted pursuant to this
Plan is disposed of in a “disqualifying disposition” within the meaning of Section 422 of the Code (a disposition within two (2) years from the date of grant of the Option or within one year after the issuance of such stock on
exercise of the Option), the holder of the stock immediately before the disposition shall promptly notify the Company in writing of the date and terms of the disposition and shall provide such other information regarding the Option as the Company
may reasonably require. 







 6.3.3 Grant Date. If an ISO is granted in anticipation of employment as provided in
Section 5.4, the Option shall be deemed granted, without further approval, on the date the grantee assumes the employment relationship forming the basis for such grant, and, in addition, satisfies all requirements of this Plan for Options
granted on that date. 
 6.3.4 Term. Notwithstanding Section 6.1.10, no ISO granted to any Ten Percent Stockholder
shall be exercisable more than five (5) years after the date of grant. 
 6.3.5 Termination of Employment. Except as
otherwise provided in the stock option agreement, if for any reason an optionee ceases to be employed by the Company or any of its Affiliates, Options that are ISOs held at the date of termination (to the extent then exercisable) may be exercised in
whole or in part at any time within ninety (90) days of the date of such termination (but in no event after the Expiration Date). For purposes of this Section 6.3.5, an optionee’s employment shall not be deemed to terminate by reason
of the optionee’s transfer from the Company to an Affiliate, or vice versa, or sick leave, military leave or other leave of absence approved by the Administrator, if the period of any such leave does not exceed ninety (90) days or, if
longer, if the optionee’s right to reemployment by the Company or any Affiliate is guaranteed either contractually or by statute. 
 6.4 Terms and Conditions Applicable Solely to SARs. In addition to the other terms and conditions applicable to SARs in this Section 6, the holder shall be entitled to receive on exercise of
an SAR only Common Stock at a fair market value equal to the benefit to be received by the exercise. 
  

	7.	MANNER OF EXERCISE 


7.1 An optionee wishing to exercise an Option or SAR shall give written notice to the Company at its principal executive office, to the
attention of the officer of the Company designated by the Administrator, accompanied by payment of the exercise price and/or withholding taxes as provided in Sections 6.1.6 and 6.1.7. The date the Company receives written notice of an exercise
hereunder accompanied by the applicable payment will be considered as the date such Option or SAR was exercised. 
 7.2 Promptly
after receipt of written notice of exercise and the applicable payments called for by Section 7.1, the Company shall, without stock issue or transfer taxes to the holder or other person entitled to exercise the Option or SAR, deliver to the
holder or such other person a certificate or certificates for the requisite number of shares of Common Stock. A holder or permitted transferee of an Option or SAR shall not have any privileges as a stockholder with respect to any shares of Common
Stock to be issued until the date of issuance (as evidenced by the appropriate entry on the books of the Company or a duly authorized transfer agent) of such shares. 
  

	8.	RESTRICTED STOCK 


8.1 Grant or Sale of Restricted Stock. 
 8.1.1 No awards of restricted stock shall be granted under this Plan after ten (10) years from the date of adoption of this Plan by the Board. 

8.1.2 The Administrator may issue shares under the Plan as a grant or for such consideration (including services, and, subject to the
Sarbanes-Oxley Act of 2002, promissory notes) as determined by the Administrator. Shares issued under the Plan shall be subject to the terms, conditions and restrictions determined by the Administrator. The restrictions may include restrictions
concerning transferability, repurchase by the Company and forfeiture of the shares issued, together with such other restrictions as may be determined by the Administrator. If shares are subject to forfeiture or repurchase by the Company, all
dividends or other distributions paid by the Company with respect to the shares may be retained by the Company until the shares are no longer subject to forfeiture or repurchase, at which time all accumulated amounts shall be paid to the recipient.
All Common Stock 







 
issued pursuant to this Section 8 shall be subject to a purchase or grant agreement, which shall be executed by the Company and the prospective recipient of the shares prior to the delivery
of certificates representing such shares to the recipient. The purchase or grant agreement may contain any terms, conditions, restrictions, representations and warranties required by the Administrator. The certificates representing the shares shall
bear any legends required by the Administrator. The Administrator may require any purchaser of restricted stock to pay to the Company in cash upon demand amounts necessary to satisfy any applicable federal, state or local tax withholding
requirements. If the purchaser fails to pay the amount demanded, the Administrator may withhold that amount from other amounts payable by the Company to the purchaser, including salary, subject to applicable law. With the consent of the
Administrator in its sole discretion, a purchaser may deliver Common Stock to the Company to satisfy this withholding obligation. Upon the issuance of restricted stock, the number of shares reserved for issuance under the Plan shall be reduced by
the number of shares issued. 
 8.2 Changes in Capital Structure. In the event of a change in the Company’s capital
structure, as described in Section 6.1.1, appropriate adjustments shall be made by the Administrator, in its sole discretion, in the number and class of restricted stock subject to this Plan and the restricted stock outstanding under this Plan;
provided, however, that the Company shall not be required to issue fractional shares as a result of any such adjustments. 

8.3 Corporate Transactions. In the event of a Corporate Transaction, as defined in Section 6.1.2 hereof, to the extent
not previously forfeited, all restricted stock shall be forfeited immediately prior to the consummation of such Corporate Transaction unless the Administrator determines otherwise in its sole discretion; provided, however, that the Administrator, in
its sole discretion, may remove any restrictions as to any restricted stock. The Administrator may, in its sole discretion, provide that all outstanding restricted stock participate in the Corporate Transaction with an equivalent stock substituted
by an applicable successor corporation subject to the restriction. 
  

	9.	EMPLOYMENT OR CONSULTING RELATIONSHIP 

 Nothing in this Plan or any Option granted hereunder shall interfere with or limit in any way the right of the Company or of any of its Affiliates to terminate the employment, consulting or advising of
any optionee or restricted stock holder at any time, nor confer upon any optionee or restricted stock holder any right to continue in the employ of, or consult or advise with, the Company or any of its Affiliates. 

 

	10.	CONDITIONS UPON ISSUANCE OF SHARES 

 10.1 Securities Act. Shares of Common Stock shall not be issued pursuant to the exercise of an Option or the receipt of restricted stock unless the exercise of such Option or such receipt of
restricted stock and the issuance and delivery of such shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended (the “Securities Act”). 

10.2 Non-Compete Agreement. As a further condition to the receipt of Common Stock pursuant to the exercise of an Option or the
receipt of restricted stock, the optionee or recipient of restricted stock may be required not to render services for any organization, or engage directly or indirectly in any business, competitive with the Company at any time during which
(i) an Option is outstanding to such Optionee and for six (6) months after any exercise of an Option or the receipt of Common Stock pursuant to the exercise of an Option and (ii) restricted stock is owned by such recipient and for six
(6) months after the restrictions on such restricted stock lapse. Failure to comply with this condition shall cause such Option and the exercise or issuance of shares thereunder and/or the award of restricted stock to be rescinded and the
benefit of such exercise, issuance or award to be repaid to the Company. 
  

	11.	NON-EXCLUSIVITY OF THIS PLAN 

 The adoption of this Plan shall not be construed as creating any limitations on the power of the Company to adopt such other incentive arrangements as it may deem desirable, including, without limitation,
the granting of stock options other than under this Plan. 








	12.	MARKET STAND-OFF 


Each optionee, holder of an SAR or recipient of restricted stock, if so requested by the Company or any representative of the underwriters
in connection with any registration of the offering of any securities of the Company under the Securities Act, shall not sell or otherwise transfer any shares of Common Stock acquired upon exercise of Options, SARs or receipt of restricted stock
during the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act; provided, however, that such restriction shall apply only to a registration statement of the Company
which includes securities to be sold on behalf of the Company to the public in an underwritten public offering under the Securities Act and the restriction period shall not exceed 90 days after the registration statement becomes effective.

  

	13.	AMENDMENTS TO PLAN 


The Board may at any time amend, alter, suspend or discontinue this Plan. Without the consent of an optionee, holder of an SAR or holder
of restricted stock, no amendment, alteration, suspension or discontinuance may adversely affect such person’s outstanding Option(s), SAR(s) or the terms applicable to restricted stock except to conform this Plan and ISOs granted under this
Plan to the requirements of federal or other tax laws relating to incentive stock options. No amendment, alteration, suspension or discontinuance shall require stockholder approval unless (a) stockholder approval is required to preserve
incentive stock option treatment for federal income tax purposes or (b) the Board otherwise concludes that stockholder approval is advisable. 
  

	14.	EFFECTIVE DATE OF PLAN; TERMINATION 

 This Plan shall become effective upon adoption by the Board; provided, however, that no Option or SAR shall be exercisable unless and until written consent of the stockholders of the
Company, or approval of stockholders of the Company voting at a validly called stockholders’ meeting, is obtained within twelve (12) months after adoption by the Board. If any Options or SARs are so granted and stockholder approval shall
not have been obtained within twelve (12) months of the date of adoption of this Plan by the Board, such Options and SARs shall terminate retroactively as of the date they were granted. Awards may be made under this Plan and exercise of Options
and SARs shall occur only after there has been compliance with all applicable federal and state securities laws. This Plan (but not Options and SARs previously granted under this Plan) shall terminate within ten (10) years from the date of its
adoption by the Board. Termination shall not affect any outstanding Options or SARs or the terms applicable to previously awarded restricted stock.
