 EXHIBIT 10.5.1 
 ICAGEN, INC. 
 2004 STOCK INCENTIVE PLAN 
 RESTRICTED STOCK UNIT AGREEMENT 
 This RESTRICTED STOCK UNIT AGREEMENT (the
“Agreement”), dated as of              (the “Date of Grant”), is delivered by Icagen, Inc., a Delaware corporation (“Icagen”), to
             (the “Grantee”), a director of Icagen. 
 RECITALS 
 The Icagen, Inc. 2004 Stock Incentive Plan (the “Plan”) provides for the grant of stock-based awards
with respect to shares of common stock, par value $0.001 per share, of Icagen (the “Common Stock”), in accordance with the terms and conditions of the Plan. The Board of Directors of Icagen (the “Board’), upon recommendation of
the Compensation Committee of the Board (the “Committee”), has determined to make a stock-based award in the form of a grant of restricted stock units, subject to the terms and conditions set forth in this Agreement and the Plan. The
Grantee may obtain a copy of the Plan by contacting the Human Resources Manager at Icagen. 
 NOW, THEREFORE, the parties to this Agreement,
intending to be legally bound hereby, agree as follows: 
 1. Grant of Restricted Stock Units. Subject to the terms and conditions set forth in this
Agreement and the Plan and as of the Date of Grant, Icagen hereby grants to the Grantee                      restricted stock units (the
“Restricted Stock Units”) under the Plan. The Grantee accepts the Restricted Stock Units and agrees to be bound by the terms and conditions of this Agreement and the Plan with respect to the Restricted Stock Units. 
 2. Restricted Unit Account. The Restricted Stock Units represent the right to receive shares of Common Stock, subject to the vesting and other terms and conditions
of this Agreement, and are not actual shares of stock. Icagen shall establish and maintain a Restricted Stock Unit account, as a bookkeeping account on its records, for the Grantee and shall record in such account the number of Restricted Stock
Units granted to the Grantee. No shares of stock shall be issued to the Grantee at the time the grant is made, and the Grantee shall not be, nor have any of the rights or privileges of, a stockholder of Icagen with respect to any Restricted Stock
Units recorded in the account. The Grantee shall not have the right to receive any dividends or other distributions with respect to Restricted Stock Units recorded in the Grantee’s account; provided, however, that the Committee may
appropriately adjust the number and kind of Restricted Stock Units in the event of a stock split, stock dividend or other change in capitalization of Icagen, as provided in the Plan. The Grantee shall not have any interest in any fund or specific
assets of Icagen by reason of this award or the Restricted Unit account established for the Grantee. 







 3. Vesting of Restricted Stock Units. 
 The Restricted Stock Units shall vest in full on December 31, 2009 (the “Vesting Date”), provided that the Grantee does not cease to serve
as a member of the Board prior to the Vesting Date. Notwithstanding the foregoing, upon a Change of Control Event, as defined in the Plan, the Restricted Stock Units shall automatically become fully vested effective immediately prior to the
consummation of such Change of Control Event. In the event of a Reorganization Event (as defined in the Plan) that is not a Change of Control Event, the provisions set forth in Section 8(c)(3)(a) of the Plan shall apply to the Restricted Stock
Units. 
 4. Issuance of Common Stock. 
 (a) When the Restricted Stock Units vest as described above, such Restricted Stock Units shall no
longer be subject to forfeiture. Subject to the terms of this Agreement, Icagen shall issue or cause to be issued to the Grantee one share of Common Stock for each whole vested Restricted Stock Unit on, or as soon as practicable after, the date the
Restricted Stock Units vest in accordance with Paragraph 3 (but in any event by the thirtieth (30th) day following such date), subject to the
satisfaction of the Grantee’s tax withholding obligations as described below. 
 (b) All obligations of Icagen and rights of Grantee
under this Agreement shall be subject to the rights of Icagen as set forth in the Plan to withhold any amounts that may be required to be withheld by Icagen for applicable taxes. In the event Icagen determines it has tax withholding obligations with
respect to the Restricted Stock Units, the Grantee agrees to arrange for the satisfaction of the minimum amount of such tax withholding obligations in a manner acceptable to Icagen as a condition to the issuance of the shares of Common Stock under
Paragraph 4(a). 
 (c) The obligation of Icagen to deliver shares hereunder shall also be subject to the condition that if at any time the
Committee shall determine in its discretion that the listing, registration or qualification of the shares of Common Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body,
is necessary or desirable as a condition of, or in connection with, the issue of shares, the shares may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free
of any conditions not acceptable to the Committee. The issuance of shares of Common Stock to the Grantee pursuant to this Agreement is subject to any applicable taxes and other laws or regulations of the United States or of any state having
jurisdiction thereof. 
 (d) The Grantee agrees to be bound by Icagen’s policies regarding transfer of shares of Common Stock and
understands that there may be certain times during the year in which the Grantee will be prohibited from selling, transferring, pledging, donating, assigning, mortgaging, hypothocating or encumbering shares. 
 5. Termination of Restricted Stock Units. If the Grantee ceases to serve as a member of the Board prior to the Vesting Date for any reason, the Restricted Stock
Units shall automatically terminate and shall be forfeited as of the date the Grantee ceases to serve as a director. No payment or issuance of Common Stock shall be made with respect to any Restricted Stock Units that terminate as described in this
Paragraph 5.

 6. Grant Subject to Plan Provisions. This grant is made pursuant to the Plan, the terms of which are incorporated
herein by reference, and in all respects shall be interpreted in accordance with the Plan. The grant and payment of the Restricted Stock Units are subject to interpretations, regulations and determinations concerning the Plan established from time
to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (i) rights and obligations with respect to withholding taxes, (ii) the registration, qualification or listing
of the shares issued under the Plan, (iii) changes in capitalization of Icagen, and (iv) other requirements of applicable law. The Committee shall have the authority to interpret and construe the Restricted Stock Units pursuant to the
terms of the Plan, and its decisions shall be conclusive as to any questions arising hereunder. 
 7. No Right to Continued Board Service. The grant
of the Restricted Stock Units shall not confer upon the Grantee any right to continued service as a director of the Company. 
 8. No Stockholder
Rights. Neither the Grantee, nor any person entitled to receive payment in the event of the Grantee’s death, shall have any of the rights and privileges of a stockholder with respect to shares of Common Stock, until certificates for shares
have been issued upon payment of Restricted Stock Units. 
 9. Assignment and Transfers. Except as the Committee may otherwise permit pursuant to the
Plan, the rights and interests of the Grantee under this Agreement may not be sold, assigned, encumbered or otherwise transferred except, in the event of the death of the Grantee, by will or by the laws of descent and distribution. In the event of
any attempt by the Grantee to alienate, assign, pledge, hypothecate, or otherwise dispose of the Restricted Stock Units or any right hereunder, except as provided for in this Agreement, or in the event of the levy or any attachment, execution or
similar process upon the rights or interests hereby conferred, Icagen may terminate the Restricted Stock Units by notice to the Grantee, and the Restricted Stock Units and all rights hereunder shall thereupon become null and void. The rights and
protections of Icagen hereunder shall extend to any successors or assigns of Icagen, and to Icagen’s parents, subsidiaries, and affiliates, as applicable. This Agreement may be assigned by Icagen without the Grantee’s consent. 

10. Agreement in Connection with Public Offering. The Grantee agrees, in connection with an underwritten public offering of Icagen’s securities pursuant
to a registration statement under the Securities Act of 1933, as amended, (i) not to sell, make short sale of, loan, grant any options for the purchase of, or otherwise dispose of any shares of Common Stock held by the Grantee (other than those
shares included in the offering) without the prior written consent of Icagen or the underwriters managing such underwritten public offering of Icagen’s securities for such number of days (not to exceed 180 days) from the effective date of such
registration statement as the managing underwriters or Icagen may require, and (ii) to execute any agreement reflecting clause (i) above as may be requested by Icagen or the managing underwriters at the time of such offering.

 11. Unfunded Arrangement. The Grantee’s rights to receive payments under this Agreement shall be no greater
than the right of an unsecured general creditor of Icagen. All payments shall be made from the general assets of Icagen, and no special or separate fund shall be established and no segregation of assets shall be made to assure payment. 

12. Tax Consequences. The Grantee acknowledges that the Grantee may be subject to adverse tax consequences as a result of the issuance, vesting and/or
distribution of the Restricted Stock Units and/or the Common Stock and understands that the Grantee should consult a tax advisor as to the tax consequences of the Restricted Stock Units and subsequent distribution of Common Stock. To the extent that
this Agreement, the issuance and vesting of the Restricted Stock Units and/or distribution of Common Stock as set forth in this Agreement is subject to Section 409A of the Internal Revenue Code of 1986, as amended, and any regulations
promulgated thereunder (the “Code”), the Grantee agrees to cooperate and work together with Icagen to timely amend this Grant to comply with Section 409A of the Code as necessary. 
 13. Applicable Law. The validity, construction, interpretation and effect of this Agreement shall be governed by and construed in accordance with the laws of the
State of Delaware, without giving effect to the conflicts of laws provisions thereof. 
 14. Notice. Any notice to Icagen provided for in this
Agreement shall be addressed to Icagen, Inc. in care of the Human Resources Manager, at the corporate headquarters of Icagen, and any notice to the Grantee shall be addressed to such Grantee at the current address shown on the payroll of Icagen, or
to such other address as the Grantee may designate to Icagen, in writing. Any notice shall be delivered by hand, sent by telecopy or enclosed in a properly sealed envelope addressed as stated above, registered and deposited, postage prepaid, in a
post office regularly maintained by the United States Postal Service.
