 2016
STOCK OPTION PLAN 
 This AGREEMENT (“Agreement”) is effective as of
[                            ] between Hot Air, Inc., a Delaware corporation (the
“Company”) and [__________] (the “Participant”). 
 Terms and Conditions 

The Company hereby grants this non-qualified stock option (the “Option”) as of
[                            ] (the “Grant Date”), pursuant to the Hot Air, Inc. 2016
Stock Option Plan, as it may be amended from time to time (the “Plan”), to purchase the number of shares of Common Stock set forth in Section 2 below to the Participant, as an Eligible Employee of
the Company or any of its Affiliates (the “Shares”). Except as otherwise indicated, any capitalized term used but not defined herein shall have the meaning ascribed to such term in the Plan. A copy of the Plan has been
delivered to the Participant. By signing and returning this Agreement, the Participant acknowledges having received and read a copy of the Plan and agrees to comply with it, this Agreement and all applicable laws and regulations. 

Accordingly, the parties hereto agree as follows: 

1. Tax Matters. No part of the Option granted hereby is intended to qualify as an “incentive stock option” under
section 422 of the Code. 
 2. Shares Subject to Option; Exercise Price. Subject in all respects to the Plan and the terms and
conditions set forth herein and therein, the Option entitles the Participant to purchase from the Company, upon exercise, [______] shares of Common Stock at an exercise price equal to $1,000 per Share (the “Exercise Price”). One-half of the Option shall be subject to vesting under Section 3(a) based on the passage of time (“Time-Based Options”), and
one-half of the Option shall be subject to vesting under Section 3(b) based on the achievement of performance objectives (“Performance-Based Options”). 

3. Vesting. Subject to the Participant not having a Termination of Employment and except as otherwise set forth in
Section 4, the Option shall become non-forfeitable and exercisable (any portion of the Option that shall have become non-forfeitable and
exercisable pursuant to this Section 3, the “Vested Options”) according to the following provisions. 

(a) Time-Based Options. 

(i) Except as otherwise provided in Section 4 hereof, the Time-Based Options shall vest and become exercisable in
the following amounts at the following times (the “Time-Based Vesting Dates”), provided that the Participant has not experienced a Termination of Employment prior to each applicable Time-Based Vesting Date. There shall be no
proportionate or partial vesting in the periods prior to each Time-Based Vesting Date and any vesting shall occur only on the applicable Time-Based Vesting Date.

 (ii) Notwithstanding Section 3(a)(i), the following shall apply with respect to the
Time-Based Options: 
 (A) in the event of a Change in Control, all unvested Time-Based Options shall immediately vest and become Vested
Options as of immediately prior to the Change in Control; 
 (B) in the event that the Participant experiences a Termination of Employment
by reason of an involuntary Termination by the Company without Cause or by the Participant for Good Reason, that percentage of the Time-Based Options subject to this Agreement that have not vested but would have vested in the calendar year of the
Participant’s Termination of Employment, in accordance with Section 3(a)(i) hereof, shall immediately vest and become Vested Options as of the date of the Participant’s Termination of Employment; 

(C) in the event that the Participant experiences a Termination of Employment by reason of death or Disability, all unvested Time-Based
Options subject to this Agreement shall immediately vest and become Vested Options as of the date of the Participant’s death or Disability, whichever applicable; and 

(D) the Board or the Committee shall be authorized, in its sole discretion, based upon its review and evaluation of the performance of the
Participant and of the Company, to accelerate the vesting of any Time-Based Options under this Agreement, at such times and upon such terms and conditions as the Board or the Committee deem advisable, and which determination shall be made on an
individual by individual basis and need not be uniform among all Plan participants. 
 (b) Performance-Based Options. Except as
otherwise provided in Section 4 hereof, 100% of the Performance-Based Options shall vest and become exercisable upon the occurrence of any Realization Event, if and solely to the extent the Sponsor has achieved a Sponsor
IRR with respect to its equity investments in Cardboard Box LLC, a Delaware limited liability company (“Cardboard Box”), equal to at least eight percent (8%) at the time of such Realization Event. The following terms used in
this Section 3(b) shall have the meanings ascribed to them below. 

  
 2 













 (i) “Realization Event” shall mean an event or transaction (or a series of
events or transactions), including, without limitation, a Change in Control or a sale or other disposition of shares of Common Stock into the public market, wherein the Sponsor receives cash, on a cumulative basis, in respect of its Common Stock.

 (ii) “Sponsor” means CP7 Warming Bag, L.P., a Delaware limited partnership, and its Affiliates. 

(iii) “Sponsor IRR” means, as of the date of any Realization Event, the cumulative internal rate of return of the Sponsor
(calculated as provided below) where the internal rate of return shall be the annually compounded rate of return which results in the following amount having a net present value equal to zero: (A) the aggregate amount of cash distributed to the
Sponsor from time to time on a cumulative basis through such date (provided that in no circumstances shall any fees paid, expenses reimbursed or tax distributions made to the Sponsor from time to time be included in this clause (A)), minus
(B) the aggregate amount of the cash invested in (and the initial gross asset value of any property (other than money) contributed to) Cardboard Box by the Sponsor, directly or indirectly, from time to time in respect of such investment. In
determining the Sponsor IRR, the following shall apply: (1) capital contributions shall be deemed to have been made on the last day of the month in which they are made (except for the initial capital contribution which shall be deemed to have
been made on December 15, 2015); (2) distributions shall be deemed to have been made on the last day of the month in which they are made; (3) all distributions shall be based on the amount distributed prior to the application of any U.S.
federal, state or local taxation to the Sponsor; (4) the rates of return shall be per annum rates and all amounts shall be calculated on a annually compounded basis, and on the basis of a 365-day year;
and (5) the Sponsor IRR shall be determined on a fully diluted basis, assuming inclusion of all shares of Common Stock underlying all then outstanding Time-Based Options and Performance-Based Options. The calculation of the Sponsor IRR upon the
occurrence of any Realization Event shall be made by the Board or the Committee in its sole and absolute discretion. 
 4. Forfeiture
Events. 
 (a) If the Participant experiences a Termination of Employment for any reason, any portion of the Option that are not
Vested Options, and that do not become Vested Options pursuant to Section 3(a)(ii) hereof as a result of such Termination of Employment, shall be forfeited immediately upon such Termination of Employment and revert back to
the Company without any payment to the Participant. 
 (b) If the Participant experiences a Termination of Employment for Cause (or upon the
discovery that the Participant engaged in Detrimental Activity), the entire Option subject to this Agreement (Vested Options or otherwise) shall be forfeited immediately upon such termination (or such discovery that the Participant engaged in
Detrimental Activity) and revert back to the Company without any payment to the Participant. 

  
 3 













 5. Exercise. 

(a) To the extent that any portion of the Option has become vested and exercisable with respect to a number of Shares, such portion of the
Option may thereafter be exercised by the Participant, in whole or in part, at any time or from time to time prior to the Expiration Date (as defined below). Notwithstanding the foregoing, the Participant may not exercise any portion of the Option
unless the offering of Shares issuable upon such exercise (i) is then registered under the Securities Act, or, if such offering is not then so registered, the Company has determined that such offering is exempt from the registration
requirements of the Securities Act and (ii) complies with all other applicable laws and regulations governing the Option, and the Participant may not exercise any portion of the Option if the Committee determines that such exercise would not be
so registered or exempt and otherwise in compliance with such laws and regulations. Unless otherwise determined by the Committee, in no event may the Option be exercised for fewer than seventy five and forty two
ten-thousandths (75.0042) Shares unless it is exercised for all Shares then remaining exercisable with respect to the Option. 

(b) To exercise the Option, unless otherwise directed or permitted by the Committee, the Participant must: 

(i) execute and deliver to the Company a properly completed Notice of Exercise in the form attached hereto as Exhibit A. 

(ii) execute and deliver such other documentation as required by the Committee (including, without limitation, any shareholder’s
agreement) which may set forth certain restrictions on transferability of the Shares acquired upon exercise, a right of first refusal or a right of first offer of the Company and other Persons with respect to Shares, and such other terms or
restrictions as the Board or Committee may from time to time establish, including without limitation whatsoever, any drag along rights, tag along rights, transfer restrictions and registration rights, and 

(iii) remit the aggregate Exercise Price to the Company in full, payable (A) by wire transfer to a bank account of the Company; or
(B) on such other terms and conditions as may be acceptable to the Committee. 
 (c) In addition, unless otherwise directed or permitted
by the Committee, the Participant must pay or provide for all applicable withholding taxes in respect of the exercise of the Option, by (i) remitting the aggregate amount of such taxes to the Company in full, in cash or by check, bank draft or
money order payable to the order of the Company, or (ii) making arrangements with the Company to have such taxes withheld from other compensation, to the extent permitted by the Committee. 

  
 4 













 6. Option Term. The term of the Option shall be until the tenth anniversary of
the Grant Date, after which time it shall expire (such tenth anniversary date, the “Expiration Date”), subject to earlier termination in the event of the Participant’s Termination of Employment as specified in the Plan
and this Agreement. Upon the Expiration Date, the Option (whether vested or not) shall automatically be cancelled for no consideration, shall no longer be exercisable, and shall cease to be outstanding. 

7. Detrimental Activity. 

(a) The provisions in the Plan regarding Detrimental Activity shall apply to the Option. In the event that the Participant engages in
Detrimental Activity prior to any exercise of the Option, the Option shall immediately thereupon terminate and expire. As a condition of the exercise of the Option, the Participant shall be required to certify in a manner acceptable to the Company
(or be deemed to have certified) that the Participant is in compliance with the terms and conditions of the Plan and that the Participant has not engaged in, and does not intend to engage in, any Detrimental Activity. In the event the Participant
engages in Detrimental Activity during the one-year period commencing on the later of the date the Option is exercised or the date of the Participant’s Termination of Employment, the Company shall be
entitled to recover from the Participant at any time within one year after such date, and the Participant shall pay over to the Company, an amount equal to any gain realized (whether at the time of exercise or thereafter) as a result of the
exercise. 
 (b) The Participant acknowledges and agrees that the restrictions herein and in the Plan regarding Detrimental Activity are
necessary for the protection of the business and goodwill of the Company and its Affiliates, and are considered by the Participant to be reasonable for such purposes. Without intending to limit the legal or equitable remedies available in the Plan
and in this Agreement, the Participant acknowledges that engaging in Detrimental Activity will cause the Company and its Affiliates material irreparable injury for which there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of such activity or threat thereof, the Company shall be entitled, in addition to the remedies provided under the Plan, to obtain from any court of competent jurisdiction a temporary
restraining order or a preliminary or permanent injunction restraining the Participant from engaging in Detrimental Activity or such other relief as may be required to specifically enforce any of the covenants in the Plan and this Agreement without
the necessity of posting a bond, and in the case of a temporary restraining order or a preliminary injunction, without having to prove special damages. 

8. Restriction on Transfer of Option. No portion of the Option shall be Transferable by the Participant other than by will or by
the laws of descent and distribution, and the Option shall be exercisable, during the Participant’s lifetime, only by the Participant. Any attempt to Transfer the Option other than in accordance with the expressed terms of the Plan shall be
void.

 9. Company Call Rights. 

(a) In the event of (i) a Termination of Employment for Cause or the discovery that the Participant engaged in Detrimental Activity or
(ii) a voluntary Termination by the Participant without Good Reason, then, the Company may at any time during the period commencing on the date of such Termination for Cause (or the discovery that the Participant engaged in Detrimental
Activity) or voluntary Termination by the Participant without Good Reason and ending on the six (6) month anniversary thereof, repurchase from the Participant any shares of Common Stock previously acquired by the Participant through the
exercise of the Option under this Agreement at a repurchase price equal to the lesser of the (A) Exercise Price, and (B) Fair Market Value as of the date of repurchase. 

(b) In the event of a voluntary Termination by the Participant for Good Reason or an involuntary Termination by the Company for any reason
other than for Cause (including Termination of Employment due to death or Disability), the Company may at any time during the six (6)-month period following the date on which the Participant incurs such Termination of Employment or, if later,
following the date on which the Participant acquires shares of Common Stock pursuant to the exercise of the Option hereunder following such Termination of Employment, as applicable: repurchase from the Participant any shares of Common Stock
previously acquired by the Participant pursuant to the exercise of the Option under this Agreement at a repurchase price equal to Fair Market Value as of the date of repurchase. 

(c) If the Company elects to exercise the call rights under this Section 9, it shall do so by delivering to the
Participant a notice of such election, specifying the number of shares to be purchased and the closing date and time of such purchase. Such closing shall take place at the Company’s principal executive offices or as otherwise determined by the
Company within sixty (60) days after the exercise of the right contained in this Section 9. The Company shall pay any amount that it shall be obligated to pay under this Section 9 in cash or
by any other method provided under the Plan (including but not limited to by delivery of an unsecured promissory note by the Company to the Participant). 

(d) Notwithstanding anything herein to the contrary, the Company shall not be obligated to repurchase any shares of Common Stock previously
acquired pursuant to the exercise of the Vested Options from the Participant, or from the estate of the Participant, and may defer such repurchase, if (i) there exists and is continuing a default or an event of default on the part of the
Company or under any guarantee or other agreement under which the Company or any of its Subsidiaries has borrowed money, (ii) such repurchase would constitute a breach of, or result in a default or an event of default on the part of the Company
or any of its Subsidiaries under, any such guarantee or agreement, (iii) such repurchase would not be permitted under any applicable laws or stock exchange rules or regulations, or (iv) such repurchase would result in adverse accounting
consequences for the Company.

fraction of any Issued Shares, except with the prior written consent of the Board, which consent may be given or withheld in the sole discretion of the Board; provided, that the following Transfers shall not require the consent of the Board:
(a) Transfers by operation of law to the estate or personal representative of a deceased or incompetent individual Participant (which estate or representative will then be subject to the same restrictions on Transfer as all other Participants)
or (b) Transfers by the Participant to an Affiliate of the Participant; provided, that the Participant making such Transfer to an Affiliate shall thereafter remain liable (jointly and severally with the transferee) for the transferee’s
obligations under this Plan and the Participant’s individual award agreement. The Participant shall pay all reasonable expenses, including attorneys’ fees and accounting fees, incurred by the Company in connection with a Transfer of Issued
Shares by the Participant.

Section 11. 
 (b) Upon the Board’s approval of a Required Sale, the Company shall deliver a Required Sale

stockholders in complete liquidation in accordance with applicable law and any organizational documents of the Company as in effect immediately prior to the Required Sale; 

(ii) the Participant shall make or provide the same representations, warranties, covenants, indemnities and agreements as any other
Participant in connection with the Required Sale (except that in the case of representations, warranties, covenants, indemnities and agreements pertaining specifically to any Participant, the Participant shall make the comparable representations,

of an Option until the end of such Lock-up Period.
