DER Account. The unvested Phantom Units (whether Time Vested Units or Performance Vested Units) shall not be entitled to receive distributions made by the Partnership to holders of common units. However, the Company shall maintain a DER Account each Participant which shall be credited with the distributions which would have been paid to the unvested Phantom Units had such Phantom Units been outstanding from and after the date of this Agreement. No interest shall accrue on the DER Account.

Dividend Equivalents. Each Phantom Share subject to this Award is hereby granted in tandem with a corresponding dividend equivalent (“DER”), which DER shall remain outstanding from the Date of Grant until the earlier of the settlement or forfeiture of the Phantom Share to which the DER corresponds. Each vested DER entitles the Participant to receive payments, subject to and in accordance with this Agreement, in an amount equal to any dividends paid by the Company in respect of the share of Common Stock underlying the Phantom Share to which such DER relates. The Company shall establish, with respect to each Phantom Share, a separate DER bookkeeping account for such Phantom Share (a “DER Account”), which shall be credited (without interest) on the applicable dividend payment dates with an amount equal to any dividends paid during the period that such Phantom Share remains outstanding with respect to the share of Common Stock underlying the Phantom Share to which such DER relates. Upon the vesting of a Phantom Share, the DER (and the DER Account) with respect to such vested Phantom Share shall also become vested. Similarly, upon the forfeiture of a Phantom Share, the DER (and the DER Account) with respect to such forfeited Phantom Share shall also be forfeited. DERs shall not entitled the Participant to any payments relating to dividends paid after the earlier to occur of the applicable Phantom Share settlement date or the forfeiture of the Phantom Share underlying such DER. Payments with respect to vested DERs shall be made as soon as practicable, and within 60 days, after the date that such DER vests.

Tandem SARs. Tandem SARs shall be exercisable only at the time and to the extent, and only to the extent, that the related Option is exercisable, subject to such provisions as the Committee may specify where the Tandem SAR is granted with respect to less than the full number of shares of Stock subject to the related Option. The Committee may, in its discretion, provide in any Award Agreement evidencing a Tandem SAR that such SAR may not be exercised without the advance approval of the Company and, if such approval is not given, then the Option shall nevertheless remain exercisable in accordance with its terms. A Tandem SAR shall terminate and cease to be exercisable no later than the date on which the related Option expires or is terminated or canceled. Upon the exercise of a Tandem SAR with respect to some or all of the shares subject to such SAR, the related Option shall be canceled automatically as to the number of shares with respect to which the Tandem SAR was exercised. Upon the exercise of an Option related to a Tandem SAR as to some or all of the shares subject to such Option, the related Tandem SAR shall be canceled automatically as to the number of shares with respect to which the related Option was exercised.

Number of Phantom Units: ​ Phantom Units, each of which is hereby granted in tandem with a corresponding DER, as further detailed in Section 3 below.

Each Option shall be accompanied by a TANDEM SAR at the SAR Base Price (per Share). The Tandem SAR constitutes an unfunded and unsecured promise of the Company to deliver (or cause to be delivered) to the Participant a combination of Shares and cash (as determined by the Committee, in its discretion, subject to the provisions of this Section 3) at the time such Tandem SAR is exercised, equal in value to the excess, if any, of the Fair Market Value per Share over the SAR Base Price per Share of the Tandem SAR. In no event shall the amount of such excess that the Company shall deliver (or cause to be delivered) to the Participant in cash exceed the minimum mandatory statutory amount of withholding taxes due to the applicable Canadian federal and provincial and applicable United States federal, state and local taxing authorities with respect to the exercise of the Tandem SAR (the "Minimum Withholding Amount").

Grant of Tandem DER. Each Phantom Unit granted hereunder is hereby granted in tandem with a corresponding DER, which shall remain outstanding from the Grant Date until the earlier of the payment or forfeiture of the related Phantom Unit, and which shall be subject to all of the terms and conditions contained in this Agreement and the Plan. Each vested DER shall entitle the Participant to receive payments, subject to and in accordance with this Agreement, in an amount equal to any distributions made by the Partnership following the Grant Date in respect of the Unit underlying the Phantom Unit to which such DER relates. The Company shall establish, with respect to each Phantom Unit, a separate DER bookkeeping account for such Phantom Unit (a “DER Account”), which shall be credited (without interest) on the applicable distribution dates with a notional amount equal to any distributions made by the Partnership during the period that such Phantom Unit remains outstanding with respect to the Unit underlying the Phantom Unit to which such DER relates. Upon the vesting of a Phantom Unit, the DER (and the DER Account) with respect to such vested Phantom Unit shall also become vested. The DER corresponding to a Phantom Unit shall expire upon the settlement of that Phantom Unit. Similarly, upon the forfeiture of a Phantom Unit, the DER (and the DER Account) with respect to such forfeited Phantom Unit shall also be forfeited without payment of consideration.

DERs: Each Phantom Unit granted under this Agreement shall be issued in tandem with a corresponding DER each of which shall entitle the Participant to receive payments in an amount equal to Partnership distributions with respect to a Unit in accordance with Section 3 below.

Grant of Tandem DER. Each Phantom Unit granted hereunder is hereby granted in tandem with a corresponding DER, which DER shall remain outstanding from the Grant Date until the earlier of the payment or forfeiture of the Phantom Unit to which it corresponds. Each vested DER shall entitle the Participant to receive payments, subject to and in accordance with this Agreement, in an amount equal to any distributions made by the Partnership in respect of the Unit underlying the Phantom Unit to which such DER relates. Such payments shall be made in cash to the extent the corresponding distribution was made in cash and shall be made in accordance with Section 5 below. The Company shall establish, with respect to each Phantom Unit, a separate DER bookkeeping account for such Phantom Unit (a “DER Account”), which shall be credited (without interest) on the applicable distribution dates with an amount equal to any distributions made by the Partnership during the period that such Phantom Unit remains outstanding with respect to the Unit underlying the Phantom Unit to which such DER relates. Upon the vesting of a Phantom Unit, the DER (and the DER Account) with respect to such vested Phantom Unit shall also become vested. Similarly, upon the forfeiture of a Phantom Unit, the DER (and the DER Account) with respect to such forfeited Phantom Unit shall also be forfeited. DERs shall not entitle the Participant to any payments relating to distributions occurring after the earlier to occur of the applicable Phantom Unit payment date or the forfeiture of the Phantom Unit underlying such DER. The DERs and any amounts that may become distributable in respect thereof shall be treated separately from the Phantom Units and the rights arising in connection therewith for purposes of Section 409A of the Code (including for purposes of the designation of the time and form of payments required by Section 409A of the Code).

Dividend Equivalents. Each Phantom Share subject to this Award is hereby granted in tandem with a corresponding dividend equivalent (“DER”), which DER shall remain outstanding from the Date of Grant until the earlier of the settlement or forfeiture of the Phantom Share to which the DER corresponds. Each vested DER entitles the Participant to receive payments, subject to and in accordance with this Agreement, in an amount equal to any dividends paid by the Company in respect of the share of Common Stock underlying the Phantom Share to which such DER relates. The Company shall establish, with respect to each Phantom Share, a separate DER bookkeeping account for such Phantom Share (a “DER Account”), which shall be credited (without interest) on the applicable dividend payment dates with an amount equal to any dividends paid during the period that such Phantom Share remains outstanding with respect to the share of Common Stock underlying the Phantom Share to which such DER relates. Upon the vesting of a Phantom Share, the DER (and the DER Account) with respect to such vested Phantom Share shall also become vested. Similarly, upon the forfeiture of a Phantom Share, the DER (and the DER Account) with respect to such forfeited Phantom Share shall also be forfeited. DERs shall not entitled the Participant to any payments relating to dividends paid after the earlier to occur of the applicable Phantom Share settlement date or the forfeiture of the Phantom Share underlying such DER. Payments with respect to vested DERs shall be made as soon as practicable, and within 60 days, after the date that such DER vests.

Tandem SARs. Tandem SARs may be granted either at the time the Option is granted or at any time thereafter while the Option remains outstanding; provided, however, that, in the case of an Incentive Stock Option, SARs may be granted only at the time of grant of the Incentive Stock Option. In the case of tandem SARs, the number of SARs granted to an Employee, Consultant or Director that shall be exercisable during a specified period shall not exceed the number of shares of Common Stock that the Employee, Consultant or Director may purchase upon the exercise of the related Option during such period. Upon the exercise of an Option, the SARs relating to the Common Stock covered by such Option shall terminate. Upon the exercise of the SARs, the related Option shall terminate to the extent of an equal number of shares of Common Stock.
