STOCKHOLDERS AGREEMENT

PREAMBLE

This Stockholders Agreement, by and among Cryo-Cell International, Inc., a Delaware corporation (the “Company”) and Mark L. Portnoy, is entered into this 12th day of March, 2018.

WHEREAS, the outside and independent directors of the Company have determined (a) that equity-based compensation for management and directors reduces the expenditure of cash and aligns the incentives of management and directors with those of the stockholders and (b) that while further equity-based compensation would further align such interests from an economic perspective such further equity-based compensation should be subject to pass-through voting and other conditions;

NOW THEREFORE, it is hereby agreed:

ARTICLE I VOTING MATTERS

1.1 Voting in Elections. At any meeting of stockholders of the Company involving the election of directors (or if action is taken by written consent of stockholders of the Company in lieu of a meeting in respect of an election of directors), the Stockholder shall vote, or cause to be voted (including, if applicable, by written consent), all Voting Securities Beneficially Owned by such Stockholder (a) up to the Voting Percentage Limit, in Stockholder’s sole discretion, and (b) in excess of the Voting Percentage Limit, in the same proportion as the Voting Securities not Beneficially Owned by the Restricted Stockholders are voted affirmatively for or against, or to withhold authority with respect to, as applicable, the election of each Person nominated to serve as a director (or, as applicable, the removal of any director) (it being understood that the Stockholder must elect to vote as contemplated by this Section 1.1 and cannot elect not to vote or to vote in any other manner).

1.2 Voting with respect to Certain Acquisitions. At any meeting of stockholders of the Company at which an Acquisition that has been approved and recommended (and such recommendation has not been withdrawn) by the Board (and any other related matter the approval of which is required to consummate such Acquisition) is submitted to a vote of the stockholders of the Company (or if action is taken with respect to such matter(s) by written consent of stockholders of the Company in lieu of a meeting), the Stockholder shall vote or cause to be voted (including by abstaining or, if applicable, taking action by written consent) all Voting Securities Beneficially Owned by such Stockholder in excess of the Voting Percentage Limit in the same proportion as the Voting Securities not Beneficially Owned by the Restricted Stockholders are voted (including by written consent) for or against, or abstain with respect to, such Acquisition (and such related matters(s)). For the avoidance of doubt, in calculating the voting requirements of the Stockholder under Section 1.2, all broker non-votes and all Voting Securities that are not present or represented at the applicable stockholder meeting shall not be considered. The Stockholder shall be free to vote or cause to be voted (including by abstaining or, if applicable, taking action by written consent), in its sole discretion, all Voting Securities Beneficially Owned by Stockholder up to and including the Voting Percentage Limit.

1.3 Voting with respect to Other Matters. At any meeting of stockholders of the Company at which any matter, other than a matter that is subject to Section 1.1 or Section 1.2, is submitted to a vote of the stockholders of the Company (or if action is taken with respect thereto by written consent of stockholders in lieu of a meeting), the Stockholder shall vote or cause to be voted (including by abstaining or, if applicable, taking action by written consent) all Voting Securities Beneficially Owned by Stockholder in excess of the Voting Percentage Limit in the same proportion as the Voting Securities not Beneficially Owned by the Stockholder or any then current officer or director are voted (including by written consent) for or against, or abstain with respect to, each such matter. For the avoidance of doubt, in calculating the voting requirements of the Stockholder under Section 1.3, all broker non-votes and all Voting Securities that are not present or represented at the applicable stockholder meeting shall not be considered. The Stockholder shall be free to vote or cause to be voted (including by abstaining or, if applicable, taking action by written consent), in their sole discretion, all Voting Securities Beneficially Owned by the Stockholder up to and including the Voting Percentage Limit for or against, or to abstain from voting on, each such matter.

1.4 Quorum. At each meeting of stockholders, the Stockholder shall cause all of the Voting Securities Beneficially Owned by the Stockholder to be present in person or by proxy for quorum purposes.

2.3 Amendment; Waiver. This Agreement may be amended, supplemented or otherwise modified, and the observance of any term hereof may be waived, only by a written instrument executed by both (i) the Company, acting through a duly appointed independent Committee of the Board or Sub-Committee thereof, and (ii) the Stockholder. Neither the failure nor delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof nor shall any single or partial exercise of any right, remedy, power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No waiver shall be effective unless it is in writing and is signed by the party asserted to have granted such waiver. Any amendment, supplement or modification to this Agreement and any waiver of any term hereof effected in accordance with this Section 2.3 shall be binding on each party hereto and all of such party’s successors and permitted assigns, whether or not such party successor or permitted assign entered into or approved such amendment, supplement or modification.

2.4 Further Assurances. Each party hereto shall sign such further documents and do and perform and cause to be done such further acts and things as any other party hereto may reasonably request to the extent necessary to carry out the intent and accomplish the purposes of this Agreement.

2.5 Assignment. This Agreement will inure to the benefit of and be binding on the parties hereto and their respective successors and permitted assigns. This Agreement may not be assigned, without the express prior written consent of the other parties hereto, and any attempted assignment, without such consent, will be null and void.

2.6 Third Parties. This Agreement does not create any rights, claims or benefits inuring to any person that is not a party hereto nor create or establish any third party beneficiary hereto. No individual stockholder shall have any individual or direct rights or claims under this Agreement.

2.7 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without regard to principles of conflicts of Laws thereof.

2.8 Jurisdiction; Waiver of Jury Trial. In any judicial proceeding involving any dispute, controversy or claim between the parties hereto arising out of or relating to this Agreement, each of the parties hereto, by execution and delivery of this Agreement, unconditionally accepts and consents to the exclusive jurisdiction and venue of the Delaware Court of Chancery and any state appellate court to which orders and judgments thereof may be appealed within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), including but not limited to the in personam and subject matter jurisdiction of those courts, or if jurisdiction over the matter is vested exclusively in federal courts, the United States District Court for the District of Delaware, and the appellate courts to which orders and judgments thereof may be appealed, waives any objections to such jurisdiction on the grounds of venue or forum non conveniens, the absence of in personam or subject matter jurisdiction and any similar grounds or any other manner permitted by Law, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. In any such judicial proceeding, the parties agree that in addition to any method for the service of process permitted or required by such courts, to the fullest extent permitted by Law, service of process may be made by delivery provided pursuant to the directions in Section 2.2. EACH OF THE PARTIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING ANY DISPUTE, CONTROVERSY OR CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT.

2.9 Specific Performance. Each party hereto acknowledges and agrees that in the event of any breach of this Agreement by any of them, the other parties hereto would be irreparably harmed and could not be made whole by monetary damages. Each party accordingly agrees to waive the defense in any action for specific performance that a remedy at law would be adequate and agrees that the parties, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to specific performance of this Agreement without the posting of bond.

2.10 Entire Agreement. This Agreement sets forth the entire understanding of the parties hereto with respect to the subject matter hereof.
