THIS OPTION GRANT AGREEMENT (the Agreement), dated as of July 2, 2007 (the Grant Date), is entered into between API
NANOTRONICS CORP., a Delaware corporation (the Company), and ARTHUR CAPE (the Option-holder).

WHEREAS, the
Option-holder is a director of the Company;

WHEREAS, the Company desires to afford the Option-holder an opportunity to purchase
shares of common stock (Common Stock) in the Company as provided in this Agreement, effective as of the Grant Date; and

WHEREAS, the Board of Directors of the Company has approved the issuance of this option to Option-holder pursuant to the API Nanotronics Corp. 2006 Equity Incentive Plan (the Plan); and

WHEREAS, the Company and the Option-holder desire to reprice the Non-Statutory Stock Option Agreement, dated as of June 20, 2007, between the
Company and the Option-holder.

NOW, THEREFORE, in consideration of the premises and the mutual covenants set forth in this
Agreement and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto have agreed, and do hereby agree, as follows:



|1. | Issuance.
|-- | ---------

This option is issued by the
Company as of the Grant Date pursuant to the Plan.

Capitalized terms used herein and not defined herein shall have the meaning set forth in
the Plan.



|2. | Grant of Option, Option Price and Term.
|-- | ---------------------------------------

a)
Grant. Subject to the terms and conditions of this Agreement, the Company hereby grants to the Option-holder, as compensation for his services as a director of the



---

Company, the right and option (Option) to purchase twenty-five thousand (25,000) shares of Common Stock of the Company (Option
Shares). This Option is intended to be neither an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the Code), nor an option granted pursuant to an employee
stock purchase plan as defined in Section 423 of the Code.

b) Option Price. For each of the Option Shares purchased, upon
purchase thereof the Option-holder shall pay to the Company One dollar thirty four and one-half cents ($1.345) (the Option Price) which the parties agree represents the fair market value of the Option Shares on the Grant Date.
Accordingly, the aggregate Option Price to purchase all of the Option Shares subject to the Option granted hereunder is $33,625 (the Aggregate Option Price).

c) No Fractional Shares. The Company shall not be required to issue any fractional Option Shares hereunder. The fair market value of any fractional Option Shares to be issued to the Option-holder upon exercise
of an Option issued under this Agreement shall be paid by the Company to the Option-holder in cash.

d) Option Term. The term of the
Option granted hereunder shall be a period from the date hereof until June 20, 2017 (the Option Period). The termination of the Option Period shall result in the termination and cancellation of such Option. In no event shall the
Option be exercisable at any time after the expiration of the Option Period.



|3. | Vesting.
|-- | --------

The Options granted herein shall
vest in accordance with the Schedule attached hereto.



|4. | Exercise of Option.
|-- | -------------------

a) Exercise for
Cash. The vested portion of this Option may be exercised, in whole at any time or in part from time to time, commencing June 21, 2008, and prior to 5:00 P.M., Toronto Time, on June 20, 2017, by the Option-holder by the surrender of
this Option (with the subscription form provided by the Company duly executed) to the Company at its principal office, together with proper payment of the Option Price times the number of shares of Common Stock to be received. Payment for Option
Shares shall be made by certified or official bank check payable to the order of the Company or if applicable, without cash pursuant to a cashless net exercise. If this Option is exercised in part, this Option must be exercised for a number of whole
shares of the Common Stock, and the Option-holder is entitled to receive a new Option covering the Option Shares which have not been exercised. Upon such surrender of this Option the Company will (a) issue a certificate or certificates in the
name of the Option-holder for the largest number of whole shares of the Common Stock to which the Option-holder shall be entitled (or mark the Option to denote the exercise) and, if this Option is exercised in whole, in lieu of any fractional share
of the Common Stock to which the Option-holder shall be entitled, pay to the Option-holder cash in an amount equal to the fair value of such fractional share (determined in such reasonable manner as the Board of Directors of the Company shall
determine), and (b) deliver the other securities and properties receivable upon the exercise of this Option, or the proportionate part thereof if this Option is exercised in part, pursuant to the provisions of this Option.

---

b) Cashless Net Exercise. At the Companys option, in lieu of exercising this Option in the
manner set forth in paragraph 4(a) above, this Option may be exercised, in whole or in part, by surrender of the Option without payment of any other consideration, commission or remuneration, by execution of the cashless exercise subscription form
(in the form provided by the Company duly executed). The number of shares to be issued in exchange for the Option will be computed by subtracting the Option Exercise Price from either (i) the last sale price of the Common Stock on the date of
receipt of the cashless exercise subscription form, or (ii) the most recent negotiated value used in connection with any sale of the Companys securities or in connection with any business combination involving the Company (the FMV
Price), and multiplying that amount by the number of shares represented by the Option, and dividing by the FMV Price as of the same date. If this Option is exercised in whole, in lieu of any fractional share of the Common Stock to which the
Option-holder shall be entitled, the Company shall pay to the Option-holder cash in an amount equal to the fair value of such fractional share (determined in such reasonable manner as the Board of Directors of the Company shall determine). If this
Option is exercised in part, this Option must be exercised for a number of whole shares of the Common Stock, and the Option-holder is entitled to receive a new Option covering the Option Shares which have not been exercised.

c) Same Day Sale. Where permitted by law and provided that a public market for the Companys stock exists: (i) through a same day
sale commitment from Option-holder and a broker-dealer that is a member of the National Association of Securities Dealers (an NASD Dealer) whereby Option-holder irrevocably elects to exercise the Option and to sell a portion
of the Shares so purchased to pay for the exercise price and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the exercise price directly to the Company; or (ii) through a margin commitment from
Option-holder and a NASD Dealer whereby Option-holder irrevocably elects to exercise the Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the exercise
price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the exercise price directly to the Company. Option-holder shall be solely responsible for any income or other tax consequences from any payment for Shares
with Option-holders Common Stock of the Company.



|5. | Termination of Service.
|-- | -----------------------

a) Upon the
termination of the Option-holders service as a Director for any reason other than death or Disability, Termination for Misconduct, or by order of any Regulatory Authority, the Option-holders Options shall be exercisable only as to those
Options which were vested at the date of termination and only for a period of 90 days following termination unless otherwise determined by the Committee in its sole discretion.



3



---

b) In the event of termination for death or Disability, the Option-holders Option shall be
exercisable only as to those Options which were vested at the date of termination as a Director and only for a period of twelve months following termination unless otherwise determined by the Committee in its sole discretion.

c) In the event of Termination for Misconduct or by order of a Regulatory Authority, all rights under the Option-holders Options shall expire upon
termination of employment.

d) The vesting of all or a part of the Options granted hereunder may be accelerated, in the sole discretion of
the Board, in the event there is a Change in Control of the Company.



|6. | Reservation of Option Shares.
|-- | -----------------------------

The Company
agrees that, prior to the expiration of this Option, the Company will at all times have authorized and in reserve, and will keep available, solely for issuance or delivery upon the exercise of this Option, the shares of the Common Stock and other
securities and properties as from time to time shall be receivable upon the exercise of this Option, free and clear of all restrictions on sale or transfer (except for applicable state or federal securities laws restrictions) and free and clear of
all pre-emptive rights.



|7. | Mergers, Recapitalization, Stock Splits, Etc.
|-- | ---------------------------------------------

The provisions of Sections 14 and 17 of the Plan, as amended effective the Effective Date, shall govern all Options in the event of any reorganization, merger, consolidation, recapitalization, reclassification, change in par value, stock
split-up, combination of shares or dividend payable in capital stock, or other such transaction described under Sections 14 and 17 of the Plan, and the Company reserves all discretion provided therein.



|8. | Fully Paid Stock, Taxes.
|-- | ------------------------

The Company agrees
that the shares of the Common Stock represented by each and every certificate for Option Shares delivered on the exercise of this Option shall, at the time of such delivery, be validly issued and outstanding, fully paid and nonassessable, and not
subject to pre-emptive rights, and the Company will take all such actions as may be necessary to assure that the par value or stated value, if any, per share of the Common Stock is at all times equal to or less than the then Option Price. The
Company further covenants and agrees that it will pay, when due and payable, any and all Federal and state stamp, original issue or similar taxes which may be payable in respect of the issue of any Option Share or certificate therefor.



|9. | Loss, etc., of Option.
|-- | ----------------------

Upon receipt of
evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Option, and of indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Option, if
