 EXHIBIT 4.2 
  

POINT THERAPEUTICS, INC. 
  
  

  
 1997 STOCK OPTION PLAN 
  

  
  
 1. Purpose. 
  
 The purpose of this plan (the
“Plan”) is to secure for POINT THERAPEUTICS, INC. (the “Company”) and its shareholders the benefits arising from capital stock ownership by employees, officers and directors of, and consultants or advisors to, the Company and its
Parent and subsidiary corporations who are expected to contribute to the Company’s future growth and success. Except where the context otherwise requires, the term “Company” shall include the parent and all present and future
subsidiaries of the Company as defined in Sections 424(e) and 424(f) of the Internal Revenue Code of 1986, as amended or replaced from time to time (the “Code”). Those provisions of the Plan which make express reference to Section 422
shall apply only to Incentive Stock Options (as that term is defined in the Plan). 
  
 2. Type of options and Administration. 
  
 (a) Types of Options. Options granted pursuant to the Plan shall be authorized by action of the Board of Directors of the Company (or a Committee designated by the Board of Directors) and may be either incentive stock
options (“Incentive Stock Options”) meeting the requirements of Section 422 of the Code or nonstatutory options which are not intended to meet the requirements of Section 422 of the Code. 
  
 (b) Administration. The Plan will be administered by the Board of Directors
of the Company, whose construction and interpretation of the terms and provisions of the Plan shall be final and conclusive. The Board of Directors may in its sole discretion grant options to purchase shares of the Company’s Common Stock
(“Common Stock”) and issue shares upon exercise of such options as provided in the Plan. The Board shall have authority, subject to the express provisions of the Plan, to construe the respective option agreements and the Plan, to
prescribe, amend and rescind rules and regulations relating to the Plan, to determine the terms and provisions of the respective option agreements, which need not be identical, and to make all other determinations in the judgment of the Board of
Directors necessary or desirable for the administration of the Plan. The Board of Directors may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any option agreement in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. No director or person acting pursuant to authority delegated by the Board of Directors shall be liable for any action or determination under
the Plan made in good faith. The Board of Directors may, to the full extent permitted by or consistent with applicable laws or regulations (including, without limitation, applicable state law and Rule 16b-3 promulgated under the Securities Exchange
Act of 1934 (the “Exchange Act”), or any successor rule (“Rule 16b-3”)), delegate any or all of its powers under the Plan to a committee (the “Committee”) appointed by the Board of Directors, and if the Committee is so
appointed all references to the Board of Directors in the Plan shall mean and relate to such Committee. 
  

 1 

 (c) Applicability of Rule 16b-3. Those provisions of the Plan which make express reference to Rule 16b-3
shall apply only to such persons as are required to file reports under Section 16(a) of the Exchange Act (a “Reporting Person”). 
  
 3. Eligibility. 
  
 (a) General. Options may be granted to persons who are, at the time of grant, employees, officers or directors of, or consultants or advisors to, the
Company; provided, that the class of employees to whom Incentive Stock Options may be granted shall be limited to all employees of the Company. A person who has been granted an option may, if he or she is otherwise eligible, be granted additional
options if the Board of Directors shall so determine. 
  
 (b)
Grant of Options to Directors and officers. From and after the registration of the Common Stock of the Company under the Exchange Act, the selection of a director or an officer (as the terms “director” and “officer” are defined
for purposes of Rule 16b-3) as a recipient of an option, the timing of the option grant, the exercise price of the option and the number of shares subject to the option shall be determined either (i) by the Board of Directors, of which all members
shall be “disinterested persons” (as hereinafter defined), or (ii) by one or more directors having full authority to act in the matter, who shall be a “disinterested person.” For the purposes of the Plan, a director shall be
deemed to be a “disinterested person” only if such person qualifies as a “disinterested person” within the meaning of Rule 16b-3, as such term is interpreted from time to time. 
  
 4. Stock Subject to Plan. 
  
 Subject to adjustment as provided in Section 15 below, the maximum number of
shares of Common Stock of the Company which may be issued and sold under the Plan is nine hundred ten thousand one hundred twenty three (910,123) shares. If an option granted under the Plan shall expire or terminate for any reason without having
been exercised in full, the unpurchased shares subject to such option shall again be available for subsequent option grants under the Plan. If shares issued upon exercise of an option under the Plan are tendered to the Company in payment of the
exercise price of an option granted under the Plan, such tendered shares shall again be available for subsequent option grants under the Plan; provided, that in no event shall such shares be made available for issuance to Reporting Persons or
pursuant to exercise of Incentive Stock Options. 
  

 2 

 5. Forms of Option Agreements. 
  
 As a condition to the grant of an option under the Plan, each recipient of an option shall execute an option agreement in
such form not inconsistent with the Plan as may be approved by the Board of Directors. Such option agreements may differ among recipients. 
  
 6. Purchase Price. 
  
 (a) General. The purchase price per share of stock deliverable upon the exercise of an option shall be determined by the Board of Directors, provided,
however, that in the case of an Incentive Stock Option, the exercise price shall not be less than 100% of the fair market value of such stock, as determined by the Board of Directors, at the time of grant of such option, or less than 110% of such
fair market value in the case of options described in Section 11(b). 
  
 (b) Payment of Purchase Price. Options granted under the Plan may provide for the payment of the exercise price by delivery of cash or a check to the order of the Company in an amount equal to the exercise price of such options, or, to the
extent provided in the applicable option agreement, (i) by delivery to the Company of shares of Common Stock of the Company already owned by the optionee having a fair market value equal in amount to the exercise price of the options being
exercised, (ii) by any other means (including, without limitation, by delivery of a promissory note of the optionee payable on such terms as are specified by the Board of Directors) which the Board of Directors determines are consistent with the
purpose of the Plan and with applicable laws and regulations (including, without limitation, the provisions of Rule 16b-3 and Regulation T promulgated by the Federal Reserve Board) or (iii) by any combination of such methods of payment. The fair
market value of any shares of the Company’s Common Stock or other non-cash consideration which may be delivered upon exercise of an option shall be determined by the Board of Directors. 
  
  

 3 

 7. Option Period. 
  
 Each option and all rights thereunder shall expire on such date as shall be set forth in the applicable option agreement,
except that, in the case of an Incentive Stock Option, such date shall not be later than ten years after the date on which the option is granted and, in all cases, options shall be subject to earlier termination as provided in the Plan. 

 
 8. Exercise of Options. 
  
 Each option granted under the Plan shall be exercisable either in full or in
installments at such time or times and during such period as shall be set forth in the agreement evidencing such option, subject to the provisions of the Plan. 
  

9. Nontransferability of Options. 
  
 Incentive Stock Options, and all options granted to Reporting Persons, shall not be assignable or transferable by the person to whom they are granted,
either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the optionee, shall be exercisable only by the optionee; provided, however, that non-statutory options may be transferred
pursuant to a qualified domestic relations order (as defined in Rule 16b-3). 
  
 10. Effect of Termination of Employment or Other Relationship. 
  
 Except as provided in Section 11(d) with respect to Incentive Stock Options, and subject to the provisions of the Plan, the Board of Directors shall
determine the period of time during which an optionee may exercise an option following (i) the termination of the optionee’s employment or other relationship with the Company or (ii) the death or disability of the optionee. Such periods shall
be set forth in the agreement evidencing such option. 
  
 11.
Incentive Stock Options. 
  
 Options granted under the
Plan which are intended to be Incentive Stock Options shall be subject to the following additional terms and conditions: 
  
 (a) Express Designation. All Incentive Stock Options granted under the Plan shall, at the time of grant, be specifically designated as such in the option
agreement covering such Incentive Stock Options. 
  
  

 4 

 (b) 10% Shareholder. If any employee to whom an Incentive Stock Option is to be granted under the Plan
is, at the time of the grant of such option, the owner of stock possessing more than 10% of the total combined voting power of all classes of stock of the Company (after taking into account the attribution of stock ownership rules of Section 424(d)
of the Code), then the following special provisions shall be applicable to the Incentive Stock Option granted to such individual: 
  
 (i) the purchase price per share of the Common Stock subject to such Incentive Stock Option shall not be less than 110% of the fair market
value of one share of Common Stock at the time of grant; and 
  
 (ii) the option exercise period shall not exceed five years from the date of grant. 
  
 (c) Dollar Limitation. For so long as the Code shall so provide, options granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended to constitute Incentive Stock Options shall not constitute Incentive Stock Options to the extent that such options, in the aggregate, become exercisable for the first time in any one calendar year for shares
of Common Stock with an aggregate fair market value (determined as of the respective date or dates of grant) of more than $100,000. 
  
 (d) Termination of Employment, Death or Disability. No Incentive Stock Option may be exercised unless, at the time of such exercise, the optionee is, and
has been continuously since the date of grant of his or her option, employed by the Company, except that: 
  
 (i) an Incentive Stock Option may be exercised within the period of three months after the date the optionee ceases to be an employee of
the Company (or within such lesser period as may be specified in the applicable option agreement); provided, that the agreement with respect to such option may designate a longer exercise period and that the exercise after such three-month period
shall be treated as the exercise of a non-statutory option under the Plan; 
  
 (ii) if the optionee dies while in the employ of the Company, or within three months after the optionee ceases to be such an employee, the Incentive Stock Option may be exercised by the person to whom it is
transferred by will or the laws of descent and distribution within the period of one year after the date of death (or within such lesser period as may be specified in the applicable option agreement); and 
  

 5 

 (iii) if the optionee becomes disabled (within the meaning of Section 22(e)(3) of the
Code or any successor provision thereto) while in the employ of the Company, the Incentive Stock Option may be exercised within the period of one year after the date the optionee ceases to be such an employee because of such disability (or within
such lesser period as may be specified in the applicable option agreement). 
  
 For all purposes of the Plan and any option granted hereunder, “employment” shall be defined in accordance with the provisions of Section 1.421-7(h) of the Income Tax Regulations (or any successor
regulations). Notwithstanding the foregoing provisions, no Incentive Stock Option may be exercised after its expiration date. 
  
 12. Additional Provisions. 
  
 (a) Additional Option Provisions. The Board of Directors may, in its sole discretion, include additional provisions in option agreements covering options
granted under the Plan, including without limitation restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to make, arrange for or guaranty loans or to transfer other property to optionees upon exercise of options, or such
other provisions as shall be determined by the Board of Directors; provided that such additional provisions shall not be inconsistent with any other term or condition of the Plan and such additional provisions shall not cause any Incentive Stock
Option granted under the Plan to fail to qualify as an Incentive Stock Option within the meaning of Section 422 of the Code. 
  
 (b) Acceleration, Extension, Etc. The Board of Directors may, in its sole discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the dates during which all, or any particular, option or options granted under the Plan may be exercised; provided, however, that no such extension shall be permitted if it
would cause the Plan to fail to comply with Section 422 of the Code or with Rule 16b-3. 
  
 13. General Restrictions. 
  
 (a) Investment Representations. The Company may require any person to whom an option is granted, as a condition of exercising such option, to give written assurances in substance and form satisfactory to the Company to the effect that such
person Is acquiring the Common Stock subject to the option for his or her own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or
appropriate in order to comply with federal and applicable state securities laws, or with covenants or representations made by the Company in connection with any public offering of its Common Stock. 
  

 6 

 (b) Compliance With Securities Laws. Each option shall be subject to the requirement that if, at any
time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject to such option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or
regulatory body, or that the disclosure of non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares thereunder, such option may not be exercised, in
whole or in part, unless such listing, registration, qualification, consent or approval, or satisfaction of such condition shall have been effected or obtained on conditions acceptable to the Board of Directors. Nothing herein shall be deemed to
require the Company to apply for or to obtain such listing, registration or qualification, or to satisfy such condition. 
  
 14. Rights as a Shareholder. 
  
 The holder of an option shall have no rights as a shareholder with respect to any shares covered by the option (including, without limitation, any rights
to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a stock certificate to him or her for such shares. No adjustment shall be made for dividends or other rights for which the record date is prior to
the date such stock certificate is issued. 
  
 15. Adjustment
Provisions for Recapitalizations and Related Transactions. 
  
 (a) General. If, through or as a result of any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or
other similar transaction, (i) the outstanding shares of Common Stock are increased, decreased or exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other
securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, an appropriate and proportionate adjustment may be made in (x) the maximum number and kind of shares reserved for
issuance under the Plan, (y) the number and kind of shares or other securities subject to any then outstanding options under the Plan, and (z) the price for each share subject to any then outstanding options under the Plan, without changing the
aggregate purchase price as to which such options remain exercisable. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Section 15 if such adjustment would cause the Plan to fail to comply with Section 422 of the Code or
with Rule 16b-3. 
  

 7 

 (b) Board Authority to Make Adjustments. Any adjustments under this Section 15 will be made by the Board
of Directors, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued under the Plan on account of any such adjustments. 
  
 16. Merger, Consolidation, Asset Sale, Liquidation, etc. 

 
 (a) General. In the event of a consolidation or merger or sale of all or
substantially all of the assets of the Company in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity or in the event of a liquidation of the Company, the Board of
Directors of the Company, or the board of directors of any corporation assuming the obligations of the Company, may, in its discretion, take any one or more of the following actions, as to outstanding options: (i) provide that such options shall be
assumed, or equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), provided that any such options substituted for Incentive Stock Options shall meet the requirements of Section 424(a) of the
Code, (ii) upon written notice to the optionees, provide that all unexercised options will terminate immediately prior to the consummation of such transaction unless exercised by the optionee within a specified period following the date of such
notice, (iii) in the event of a merger under the terms of which holders of the Common Stock of the Company will receive upon consummation thereof a cash payment for each share surrendered in the merger (the “Merger Price”), make or provide
for a cash payment to the optionees equal to the difference between (A) the Merger Price times the number of shares of Common Stock subject to such outstanding options (to the extent then exercisable at prices not in excess of the Merger Price) and
(B) the aggregate exercise price of all such outstanding options in exchange for the termination of such options, and (iv) provide that all or any outstanding options shall become exercisable in full immediately prior to such event. 
  
  

 8 

 (b) Substitute Options. The Company may grant options under the Plan in substitution for options held by
employees of another corporation who become employees of the Company, or a subsidiary of the Company, as the result of a merger or consolidation of the employing corporation with the Company or a subsidiary of the Company, or as a result of the
acquisition by the Company, or one of its subsidiaries, of property or stock of the employing corporation. The Company may direct that substitute options be granted on such terms and conditions as the Board of Directors considers appropriate in the
circumstances. 
  
 17. No Special Employment Rights.

  
 Nothing contained in the Plan or in any option shall confer
upon any optionee any right with respect to the continuation of his or her employment by the Company or interfere in any way with the right of the Company at any time to terminate such employment or to increase or decrease the compensation of the
optionee. 
  
 18. Other Employee Benefits. 
  
 Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an employee as a result of the exercise of an option or the sale of shares received upon such exercise will not constitute compensation with respect to which any other employee
benefits of such employee are determined, including, without limitation, benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically determined by the Board of Directors.

  
 19. Amendment of the Plan. 
  
 (a) The Board of Directors may at any time, and from time to time, modify or
amend the Plan in any respect, except that if at any time the approval of the shareholders of the Company is required under Section 422 of the Code or any successor provision with respect to Incentive Stock Options, or under Rule 16b-3, the Board of
Directors may not effect such modification or amendment without such approval. 
  
 (b) The termination or any modification or amendment of the Plan shall not, without the consent of an optionee, affect his or her rights under an option previously granted to him or her. With the consent of the
optionee affected, the Board of Directors may amend outstanding option agreements in a manner not inconsistent with the Plan. The Board of Directors shall have the right to amend or modify (i) the terms and provisions of the Plan and of any
outstanding Incentive Stock Options granted under the Plan to the extent necessary to qualify any or all such options for such favorable federal income tax treatment (including deferral of taxation upon exercise) as may be afforded incentive stock
options under Section 422 of the Code, and (ii) the terms and provisions of the Plan and of any outstanding option to the extent necessary to ensure the qualification of the Plan under Rule 16b-3. 
  

 9 

 20. Withholding. 
  
 (a) The Company shall have the right to deduct from payments of any kind otherwise due to the optionee any federal, state or
local taxes of any kind required by law to be withheld with respect to any shares issued upon exercise of options under the Plan. Subject to the prior approval of the Company, which may be withheld by the Company in its sole discretion, the optionee
may elect to satisfy such obligations, in whole or in part, (i) by causing the Company to withhold shares of Common Stock otherwise issuable pursuant to the exercise of an option or (ii) by delivering to the Company shares of Common Stock already
owned by the optionee. The shares so delivered or withheld shall have a fair market value equal to such withholding obligation. The fair market value of the shares used to satisfy such withholding obligation shall be determined by the Company as of
the date that the amount of tax to be withheld is to be determined. An optionee who has made an election pursuant to this Section 20(a) may only satisfy his or her withholding obligation with shares of Common Stock which are not subject to any
repurchase, forfeiture, unfulfilled vesting or other similar requirements. 
  
 (b) Notwithstanding the foregoing, in the case of a Reporting Person, no election to use shares for the payment of withholding taxes shall be effective unless made in compliance with any applicable requirements of
Rule 16b-3. 
  
 21. Cancellation and New Grant of Options,
Etc. 
  
 The Board of Directors shall have the authority to
effect, at any time and from time to time, with the consent of the affected optionees, (i) the cancellation of any or all outstanding options under the Plan and the grant in substitution therefor of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price per share which may be lower or higher than the exercise price per share of the cancelled options, or (ii) the amendment of the terms of any and all outstanding options
under the Plan to provide an option exercise price per share which is higher or lower than the then current exercise price per share of such outstanding options. 
  
  

 10 

 22. Effective Date and Duration of the Plan. 
  
 (a) Effective Date. The Plan shall become effective as of January 24, 1997,
but no Incentive Stock Option granted under the Plan shall become exercisable unless and until the Plan shall have been approved by the Company’s shareholders. If such shareholder approval is not obtained within twelve months after the
effective date of the Plan, no options previously granted under the Plan shall be deemed to be Incentive Stock Options and no Incentive Stock Options shall be granted thereafter. Amendments to the Plan not requiring shareholder approval shall become
effective when adopted by the Board of Directors; amendments requiring shareholder approval (as provided in Section 19) shall become effective when adopted by the Board of Directors, but no Incentive Stock Option granted after the date of such
amendment shall become exercisable (to the extent that such amendment to the Plan was required to enable the Company to grant such Incentive Stock Option to a particular optionee) unless and until such amendment shall have been approved by the
Company’s shareholders. If such shareholder approval is not obtained within twelve months of the Board’s adoption of such amendment, any Incentive Stock Options granted on or after the date of such amendment shall terminate to the extent
that such amendment to the Plan was required to enable the Company to grant such option to a particular optionee. Subject to this limitation, options may be granted under the Plan at any time after the effective date and before the date fixed for
termination of the Plan. 
  
 (b) Termination. Unless sooner
terminated in accordance with Section 16, the Plan shall terminate, with respect to Incentive Stock Options, upon the earlier of (i) the close of business on the day next preceding the tenth anniversary of the date of its adoption by the Board of
Directors, or (ii) the date on which all shares available for issuance under the Plan shall have been issued pursuant to the exercise or cancellation of options granted under the Plan. Unless sooner terminated in accordance with Section 16, the Plan
shall terminate with respect to options which are not Incentive Stock Options on the date specified in (ii) above. If the date of termination is determined under (i) above, then options outstanding on such date shall continue to have force and
effect in accordance with the provisions of the instruments evidencing such options. 
  
 23. Provision for Foreign Participants. 
  
 The Board of Directors may, without amending the Plan, modify awards or options granted to participants who are foreign nationals or employed outside the United States to recognize differences in laws, rules,
regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters.

 EXHIBIT 4.3 
  

CHANNELL COMMERCIAL CORPORATION 
  
 1996 INCENTIVE STOCK PLAN, AS AMENDED 
  
 1. Purpose. The purpose of this 1996 Incentive Stock Plan (this “PLAN”) is to secure for the Company and its stockholders the benefits arising from stock
ownership by key employees, directors and other service providers as the Committee (as hereinafter defined) may from time-to-time determine. 
  
 With respect to Stock Options (as hereinafter defined), the Plan will provide a means whereby key employees, directors and other service providers of the
Company may purchase shares of Common Stock, par value $.01 per share, of the Company (“COMMON STOCK”) (i) pursuant to Stock Options that will qualify as “incentive stock options” under Section 422 of the Internal Revenue Code of
1986, as amended (the “CODE”), and (ii) pursuant to “non-incentive” or “non-qualified” Stock Options. 
  
 2. Administration. The Plan shall be administered by the Board of Directors of the Company or, in the discretion of the Board, a Committee (in either case, the
“COMMITTEE”) consisting of two or more directors of the Company to whom administration of the Plan has been duly delegated. If the Committee is not the entire Board of Directors, the Committee shall be appointed by the Board of Directors
of the Company. From and after such time as the Company is subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “EXCHANGE ACT”), no director shall be appointed to or shall
serve on the Committee who has been granted or awarded equity securities of the Company pursuant to the Plan or (except any such grant or award that does not disqualify such director as a “disinterested person” under Rule 16b-3 promulgated
under the Exchange Act) any other plan of the Company or its affiliates during the period of one year prior to such appointment. Except as otherwise provided in the Company’s Bylaws, any action of the Committee with respect to administration of
the Plan shall be taken by a majority vote at a meeting at which a quorum is duly constituted or by unanimous written consent of the Committee’s members. 
  

Subject to the provisions of the Plan, the Committee shall have sole and final authority (i) to construe and interpret the Plan, (ii) to define the
terms used herein, (iii) to prescribe, amend and rescind rules and regulations relating to the Plan, (iv) to make awards of Restricted Shares and Stock Options hereunder, (v) to determine the individuals to whom and the time or times at which such
awards shall be made, the number of shares of Common Stock to be subject to such awards, the vesting of such awards and the other terms of such awards, (vi) in the case of Stock Options, to determine whether such Stock Options shall be intended as
“incentive stock options” or “non-incentive” or “non-qualified” Stock Options under Section 422 of the Code, and (vii) to make all other determinations necessary or advisable for the administration of the Plan. All
determinations and interpretations made by the Committee shall be binding and conclusive on all participants in the Plan and their legal representatives and beneficiaries. 
  
 3. Shares Subject to the Plan. The shares to be allocated under this Plan shall consist of the Company’s authorized but unissued
Common Stock. Subject to adjustment as provided in Section 7 hereof, the aggregate number of shares of Common Stock that may be allocated to awards made to participants shall not exceed one million five hundred thousand (1,500,000) of such shares.
Shares of Common Stock issued pursuant to the Plan and subsequently reacquired by the Company shall be available for reissuance under the Plan, and shares of Common Stock that are subject to Stock Options that lapse or terminate without exercise
shall be available to be subject to newly issued Stock Options under the Plan. 
  
 4. Eligibility and Participation. All key employees, directors and other service providers (excluding Committee members to the extent provided in Section 2) of the Company shall be eligible for selection to participate in the Plan
(each a “PARTICIPANT”). 
  

	5.	Awards. 

  

 1 

 (a) A Participant may receive one or more awards hereunder, at any time and from time-to-time, as
determined by the Committee. As determined by the Committee, awards may be in the form of (i) grants of restricted stock the vesting of which is subject to certain conditions to be determined by the Committee (“RESTRICTED SHARES”), (ii)
options to purchase Common Stock (“STOCK OPTIONS”), or (iii) any combination of the foregoing. All awards of Restricted Shares shall be pursuant to, and shall be subject to the terms and restrictions provided in, a Restricted Stock
Agreement substantially in the form attached to this Plan as Exhibit A or such alternative form (consistent with the terms of this Plan) as the Committee may choose from time-to-time; and all awards of Stock Options shall be pursuant to, and shall
be subject to the terms and restrictions provided in, either (i) an Incentive Stock Option Agreement substantially in the form attached to this Plan as Exhibit B or such alternative form (consistent with the terms of this Plan) as the Committee may
choose from time-to-time or (ii) a Nonqualified Stock Option Agreement substantially in the form attached to this Plan as Exhibit C or such alternative form (consistent with the terms of this Plan) as the Committee may choose from time-to-time.
Subject to the terms of this Plan, the Committee shall determine the exact terms and restrictions included in each of the foregoing agreements, as applicable, with respect to each award to a Participant. 
  
 (b) In addition to awards that may be granted pursuant to paragraph 5(a)
hereof, on the date of each of the Company’s annual stockholder meetings, each non-management director (including non-executive officers who serve as directors) serving on the Board of Directors immediately following such meeting shall receive
1,000 non-qualified Stock Options, which shall (i) have an exercise price equal to the fair market value of the Common Stock on the date such options are granted, (ii) vest at a rate of 33-1/3% per year commencing on the first anniversary of the
date of issuance and (iii) have a term of ten years. For purposes hereof, “fair market value” of a share of Common Stock of the Company shall be determined for purposes of this Plan by reference to the closing price on the principal stock
exchange on which such shares are then listed or, if such shares are not then listed on a stock exchange, by reference to the closing price (if approved for quotation on the NASDAQ National Market System) or the mean between the bid and asked prise
(if other over-the-counter issue) of a share as supplied by the National Association of Securities Dealers, Inc. through NASDAQ (or its successor in function), in each case as reported by The Wall Street Journal for the business day immediately
preceding the date on which the option is exercised (or, if for any reason no such price is available, in such other manner as the Committee may deem appropriate to reflect the then fair market value thereof). 
  
 6. Provisions Applicable to Incentive Stock Options. No Stock Option intended as an
“incentive stock option” within the meaning of Section 422 of the Code shall be granted to any person who owns shares of the Company’s or any of its parent or subsidiary corporations outstanding Common Stock on such other capital
stock as may hereinafter be issued by the Company or any of its parent or subsidiary corporations possessing more than ten percent (10%) of the total combine voting power of all classes of stock of the Company or any of such corporations, unless the
purchase price of such Stock Option is at least one hundred ten percent (110%) of the per share fair market value of the Common Stock on the date the Stock Option is granted and such Stock Option by its terms is not exercisable after the expiration
of five (5) years from the date such Stock Option is granted. In addition, no Stock Option intended as an “incentive stock option” shall be issued to any Participant with a purchase price of less than one hundred percent (100%) of the per
share fair market value of the Common Stock on the date the Stock Option is granted or with a term of longer than ten (10) years from the date such Stock Option is granted. 
  
 If a holder of an “incentive stock option” ceases to be employed by the Company or any subsidiary of the Company
for any reason other than the option holder’s death or permanent disability (within the meaning of Section 22(e)(3) of the Code), the option holder’s “incentive stock option” shall not be entitled to incentive treatment under the
Code if exercised after more than three months after the date the option holder ceased to be an employee of one of such corporations (unless by its terms such Stock Option sooner expires). If a holder of an “incentive stock option” ceases
to be employed by the Company or any subsidiary of the Company on account of death or permanent disability (within the meaning of Section 22(e)(3) of the Code), such Stock Option shall not be entitled to incentive treatment under the Code if
exercised after one year after the date of such death or permanent disability unless by its terms it sooner expires. During such period after death, any vested unexercised portion of the Stock Option may be exercised by the person or persons to whom
the option holder’s rights under the Stock Option shall pass by will or the laws of descent and distribution.

 To the extent that the aggregate fair market value of Common Stock or other capital stock with respect to
which “incentive stock options” are exercisable for the first time by any individual during any calendar year (under all plans of the Company and its parent and subsidiary corporations) exceeds $100,000, such stock Options shall be treated
as Stock Options which ar not “incentive stock options.” 
  
 7.
Adjustments. If the outstanding shares of the Common Stock of the Company are increased, decreased, changed into or exchanged for a different number or kind of shares or securities of the Company through: 
  

	 	(i)	a distribution or payment of a dividend on the Common Stock in shares of Common Stock; 

  

	 	(ii)	subdivision or reclassification, in a stock split or similar transaction, of the outstanding shares of Common Stock into a greater number of shares; 

  

	 	(iii)	combination or reclassification of, in a reverse stock split or similar transaction, the outstanding shares of Common Stock into a smaller number of shares; or

  

	 	(iv)	issuance of any shares of capital stock by reclassification of the Common Stock; 

  
 then an appropriate and proportionate adjustment shall be made in the maximum number and kind of shares which may be awarded under this
Plan. 
  
 Adjustments under this paragraph 7 shall be made by the
Committee, whose determination as to what adjustments shall be made, and the extent thereof, shall be final, binding and conclusive. 
  
 8. Amendment and Termination of Plan. The Committee may at any time suspend or terminate the Plan. The Committee may also at any time amend or revise the terms of
the Plan. 
  
 Notwithstanding the foregoing, no amendment,
suspension or termination of the Plan that would materially adversely affect any rights or obligations of any Participant under any Restricted Stock Agreement or Management Stock Option and Stockholders Agreement shall be effective as to such
Participant unless there shall have been specific action of the Committee and consent of the Participant. 
  
 9. No Employment Rights. The selection of any person to receive an award under this Plan shall not give such person any right to be retained in the employment of the Company or any of its subsidiaries or any of
their affiliates and the right and the power of the Company or any of its subsidiaries or any of their affiliates to discharge any such person shall not be affected by such award. No person shall have any right or claim whatever, directly,
indirectly or by implication, to receive an award, nor any expectancy thereof, unless and until an award in fact shall have been made to such person by the Committee as provided herein. The award to any person hereunder at any time shall not create
any right or implication that any other or further award may or shall be made at another time. Each award hereunder shall be separate and distinct from every other award and shall not be construed as a part of any continuing series of awards or
compensation. 
  
 10. Plan Not Exclusive. The Plan is not exclusive. The
Company may have other plans, programs and arrangements for compensation or the issuance of shares or options. The Plan does not require that Participants hereunder be precluded from participation in such other plans, programs and arrangements.

  
 11. Term. The term of this Plan shall commence as of the earlier to
occur of its adoption by the Board of Directors of the Company or its approval by the stockholders of the Company and shall expire on the ninetieth (90th) day after the tenth (10th) anniversary of such date, unless earlier terminated.
