of termination of your employment due to Permanent Disability, as applicable, and the denominator of which is 365. Any amount payable to you under this Section 3(b) shall be paid to you within the first two and one-half months following the end of the calendar year to which such Annual Bonus corresponds. Notwithstanding anything to the contrary set forth herein, you shall not be entitled any payment pursuant to this Section 3(b) unless you (or your beneficiary previously designated in writing to the Company or, if no such beneficiary has been so designated, your estate, as applicable) have, at the written request of the Company or Holdco, executed the Release (which such form may be modified by the Company to the extent necessary to reflect execution by a person other than you) no later than forty-five (45) days following the date of termination (which period shall be sixty-five (65) days following the date of termination in the case of a termination of your employment due to your death) and shall not have revoked such release in accordance with its terms.

4. Term. This agreement will remain in effect for so long as you are employed by the Company or Holdco, unless earlier terminated by the mutual consent of you and the Company and Holdco.

5. Confidential Information. You shall hold in a fiduciary capacity for the benefit of the Company and Holdco all secret or confidential information, knowledge or data relating to the Company, Holdco or any company affiliated with the Company or Holdco and their respective businesses that you obtain during your employment by the Company and Holdco (whether before, during or after such employment period) and that is not public knowledge (other than as a result of your violation of this Section 5) (“Confidential Information”).

Exhibit A

FORM OF RELEASE OF CLAIMS

This Release of Claims is provided by me, Michael Correale, pursuant to the letter agreement between me and Party City Holdco, Inc. (the “Company”) dated as of March 24, 2015 (the “Letter Agreement”).

This Release of Claims is given in consideration of the severance benefits to be provided to me in connection with the termination of my employment under Section 3(a) or 3(b), as applicable, of the Letter Agreement (the “Separation Payments”), which are conditioned on my signing this Release of Claims and to which I am not otherwise entitled, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged. On my own behalf and that of my heirs, executors, administrators, beneficiaries, representatives and assigns, and all others connected with or claiming through me, I hereby release and forever discharge the Company from any and all causes of action, rights or claims of any type or description, known or unknown, which I have had in the past, now have or might have, through the date of my signing of this Release of Claims. This includes, without limitation, any and all causes of action, rights or claims in any way resulting from, arising out of or connected with my employment by the Company or the termination of that employment or pursuant to any federal, state or local law, regulation or other requirement, including without limitation Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Age Discrimination in Employment Act, the fair employment practices statutes of the state or states in which I have provided services to the Company or any other federal, state, local or foreign law, all as amended, any contracts of employment, any tort claims, or any agreements, plans or policies.

Nothing in this Release of Claims shall be construed to prohibit you from filing a charge with or participating in any investigation or proceeding conducted by the federal Equal Employment Opportunity Commission or a comparable state or local agency, except that you hereby agree to waive your right to recover monetary damages or other individual relief in any charge, complaint or lawsuit filed by you or by anyone else on your behalf.

For purposes of this Release of Claims, the word “Company” always includes the Company, Holdco, the subsidiaries and affiliates of the Company or Holdco and all of their respective past, present and future officers, directors, trustees, shareholders, employees, employee benefit plans and any of the trustees or administrators thereof, agents, general and limited partners, members, managers, investors, joint venturers, representatives, predecessors, successors and assigns, and all others connected with any of them, both individually and in their official capacities.

Excluded from the scope of this Release of Claims are any rights to benefits that were vested under the Company’s employee benefit plans on the date on which your employment with the Company terminated, in accordance with the terms of such plans.

In signing this Release of Claims, I give the Company assurance that I have returned to the Company any and all documents, materials and information related to the business, whether

present or otherwise, of the Company and all keys and other property of the Company that were in my possession or control, all as required by and consistent with Section 5 of the Letter Agreement. I agree that I will not, for any purpose, attempt to access or use any computer or computer network or system of the Company, including without limitation their electronic mail systems. I further acknowledge that I have disclosed to the Company all passwords necessary or desirable to enable the Company to access all information which I have password-protected on its computer network or system.

In signing this Release of Claims, I agree that I have been paid in full all compensation due to me, whether for services rendered by me to the Company or otherwise, through the date on which my employment with the Company terminated and that, exclusive only of the Separation Payments, no further compensation of any kind shall be due to me by the Company, whether arising under the Letter Agreement or otherwise, in connection with my employment or the termination thereof. I also agree that except for any right my eligible dependents and I may have to continue participation in the Company’s health and dental plans under the federal law commonly known as COBRA, my right to participate in any employee benefit plan of the Company will be determined in accordance with the terms of such plan.

I acknowledge that my eligibility for the Separation Payments is not only contingent on my signing and returning this Release of Claims to the Company in a timely manner and not revoking it thereafter, but also is subject to my compliance with the covenants contained in the Letter Agreement.

In signing this Release of Claims, I acknowledge that I have not relied on any promises or representations, express or implied, that are not set forth expressly in this Release of Claims. I further acknowledge that I am waiving and releasing any rights I may have under the Age Discrimination in Employment Act of 1967, as amended (“ADEA”), and that this waiver and release is knowing and voluntary and is being done with a full understanding of its terms. I agree that the consideration given for this waiver and release is in addition to anything of value to which I was already entitled. I further acknowledge that I have been advised by this writing as required by the ADEA that:

1. I have the right to and am advised by the Company to consult with an attorney prior to executing this Release of Claims; and I acknowledge that I have had sufficient time to consider this Release of Claims and to consult with an attorney, if I wished to do so, or to consult with any other person of my choosing before signing;

2. I may not sign this Release of Claims prior to the termination of my employment, but that I may consider the terms of this Release of Claims for up to twenty-one days (or, if the Company so instructs me in writing, for up to forty-five days) from the later of the date my employment with the Company terminates or the date I receive this Release of Claims;

3. I have seven (7) days following execution of this Release of Claims to revoke this Release of Claims; and

4. This Release of Claims shall not be effective until the revocation period has expired.

Intending to be legally bound, I have signed this Release of Claims as of the date written below.
