At the direction of the Committee, you are hereby notified that on November 6, 2006 (the Date of
Grant) the Committee has granted to you a warrant to purchase shares of Common Stock of the Corporation (the Warrant), pursuant to the Corporations 2006 Equity Incentive Plan (the Plan), as amended from time to
time, which is incorporated herein by reference and made a part of this agreement. This agreement evidences the Warrant that was granted to you. Capitalized terms not otherwise defined herein shall have the same meanings as in the Plan.



| | 1. | Subject in all respects to the Plan and the terms and conditions set forth herein and therein, you are hereby granted a Warrant to purchase from the Corporation 2,500,000 shares of
Common Stock (the Shares) at the exercise price of $0.461 per share (the Warrant Price). This Warrant is being issued in connection with the exchange of shares of common stock and warrants of API Electronics Group Corp.
(API) for (i) shares of common stock of the Corporation, or exchangeable shares of RVI Sub, Inc. and (ii) warrants of the Corporation (the Combination Transaction), respectively. The number of Shares underlying the
Warrant and the Warrant Price reflect the exchange ratio of the Combination Transaction.

| | 2. | Subject to the termination provisions of the Plan, the Warrant shall expire on January 27, 2011 (the Expiration Date), which is the same expiration date as the
warrants to purchase shares of API that you exchanged for this Warrant.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | Subject to the termination provisions of the Plan, this Warrant may be exercised at any time and from time to time from and including the Date of Grant up to 5:00 p.m. (Eastern
Standard Time) on the Expiration Date by delivery to the Committee or its designee an Exercise Notice, in the form attached as Exhibit A to this Warrant Certificate, together with this Notice and Agreement of Stock Warrant and a
certified check, bank draft or money order payable to API NANOTRONICS GROUP CORP. in an amount equal to the product of the Exercise Price and the number of Shares for which this Warrant is being exercised and otherwise in accordance with
the Plan.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4. | The warrant is nontransferable, other than as may be occasioned by your death, and then only to your estate or according to the terms of your will or the provisions of applicable
laws of descent and distribution.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the event that the right to exercise the Warrant is passed to your estate, or to a
person to whom such right devolves by reason of your death, then the Warrant shall be nontransferable in the hands of your executor or administrator or of such person, except that the Warrant may be distributed by your executor or administrator to
the distributees of your estate as a part of your estate.



| | 5. | Enclosed for your careful review is a copy of the Plan governing the Warrant. At the time or times when you wish to exercise the Warrant, in whole or in part, please refer to the
provisions of the Plan dealing with methods and formalities of exercise of the Warrant. The Corporation shall have the right, and is hereby authorized, to withhold from any payment due or transfer made under the Warrant, or from any compensation
owing to you, applicable withholding taxes, if any.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Neither the Plan nor this agreement will be construed as giving you the
right to be retained in the employ of the Corporation or as a consultant to the Corporation or its affiliates, and the Corporation or its affiliates may at any time terminate your employment or consulting engagement free from any liability or any
claim under the Plan or this agreement, except as otherwise expressly provided herein.



| | 6. | This agreement shall be governed by and construed in accordance with the laws of Delaware, without regard to the conflicts of laws provisions thereof, and shall be subject in all
respects to terms of the Plan. If any one or more provisions of this agreement shall be found to be illegal or unenforceable in any respect, the validity and enforceability of the remaining provisions hereof shall not in any way be affected or
impaired thereby. This agreement and the Plan contain the entire agreement between the Corporation and you relating to the Warrant and the other matters set forth herein. This agreement is subject to the terms and conditions of the Plan. In the
event of any inconsistent provisions between this agreement and the Plan, the Plan shall govern. Except as expressly provided in this agreement or the Plan with respect to certain actions permitted to be taken by the Committee with respect to this
agreement and the terms of the Warrant, this agreement may not be amended, modified, changed, or waived other than by written instrument signed by the parties hereto. This agreement may be executed in counterparts, each of which shall be an original
with the same effect as if the signatures were upon the same instrument.
