As Holder of Common Stock Purchase Warrants of Cancer Genetics, Inc.

Dear Holder:

Cancer Genetics, Inc. (the “Company”) desires to amend the Securities Purchase Agreement, dated as of May 19, 2016, between the Company and the purchasers signatory thereto (the “May 2016 Purchase Agreement”) and the Securities Purchase Agreement, dated as of September 8, 2016, between the Company and the purchasers signatory thereto pursuant to which the Company issued the Exchange Warrants (as defined below) (the “September 2016 Purchase Agreement” and, collectively with the May 2016 Purchase Agreement, the “Purchase Agreements” and, each, a “Purchase Agreement”). Each Purchase Agreement provides that it may be modified and amended in a written instrument signed by the Company and holders of at least 67% of the issuable Warrant Shares (as defined in the respective Purchase Agreements).

We understand that you (the “Holder”) are a holder of (i) Common Stock purchase warrants of the Company with an Exercisability Date of November 25, 2016 issued pursuant to the May 2016 Purchase Agreement and/or (ii) Common Stock purchase warrants of the Company with an Exercisability Date of March 14, 2017 issued pursuant to the September 2016 Purchase Agreement (the “Exchange Warrants”). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Purchase Agreements.

By executing this letter agreement (this “Agreement”), the Holder irrevocably (i) agrees that each Purchase Agreement, as applicable, shall be modified and amended to delete, in its entirety, Section 4.11(b) of each Purchase Agreement, and (ii) solely with respect to this Agreement, waives, for itself, the provisions of Section 4.12 of each Purchase Agreement, as applicable, provided, however, that the waiver in this clause (ii) is conditional upon the Company’s acknowledgement and agreement to the Holder that, if any holder of Exchange Warrants communicates to the Company within 30 days of the date of the 8-K Filing (as defined below) that such holder wishes to exchange such holder’s Exchange Warrants for Exchange Shares, the Company shall effect a Warrant Exchange for such holder using the same ratio as contemplated pursuant to the Warrant Exchange set forth herein. This amendment shall be effective, (a) as to the May 2016 Purchase Agreement, immediately upon the Company’s receipt of Other Agreements (as defined below) from Other Holders (as defined below) who hold, with the Holder, an aggregate of at least 67% of the Warrant Shares issuable pursuant to Warrants issued pursuant to the May 2016 Purchase Agreement and (b) as to the September 2016 Purchase Agreement, immediately upon the Company’s receipt of Other Agreements (as defined below) from Other Holders (as defined below) who hold, with the Holder, an aggregate of at least 67% of the Warrant Shares issuable pursuant to Warrants issued pursuant to the September 2016 Purchase Agreement (the latter such date being the “Effective Date”).

In addition, the Company hereby offers you the opportunity to exchange in full all of the Exchange Warrants held by you (the “Warrant Exchange”), in exchange for 0.2 shares of Common Stock (“Exchange Shares”) for each share of Common Stock issuable upon Exercise of the Exchange Warrant. Notwithstanding anything herein to the contrary, in the event that the Warrant Exchange would cause the Holder to exceed the Beneficial Ownership Limitation in the Exchange Warrant, the Company shall only issue such number of shares of Common Stock to the Holder that would not cause the Holder to exceed the Beneficial Ownership Limitation with the balance to be held in abeyance until written notice from the Holder that the balance (or portion thereof) may be issued in compliance with the Beneficial Ownership Limitation. The Company agrees that the Warrant Exchange shall in no event result in the Holder beneficially owning more than the Beneficial Ownership Limitation. Within two Trading Days of the Effective Date, the Company shall deliver the Exchange Shares to the DTC account of the Holder via the DWAC system in accordance with the DTC Instructions provided by the Holder on the Signature page hereto. The terms of the Warrant Exchange, including but not limited to the obligations to deliver the Exchange Shares, shall remain in effect as if the acceptance of this offer was a formal Notice of Exercise (including but not limited to any liquidated damages and compensation in the event of late delivery of the Exchange Shares). The Holder hereby acknowledges that upon receipt of the Exchange Shares, such Holder’s Exchange Warrants exchanged for such Exchange Shares shall be deemed to be cancelled without further action required by either the Company or the Holder. Nonetheless, the Holder shall use reasonable commercial efforts to return the original Exchange Warrants to the Company for cancellation, or to confirm in writing to the Company that the Exchange Warrants have been destroyed, as promptly as practical.

The Exchange Shares are being issued in a cashless exchange for the Exchange Warrants and the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the holding period of the Exchange Shares under Rule 144 shall be tacked on to the holding period of the Exchange Warrants. The Company agrees not to take any position contrary to the aforementioned representation.

Expressly subject to the paragraph immediately following this paragraph below, Holder may accept this offer by signing this letter below, with such acceptance constituting Holder’s exchange in full of the Exchange Warrant for Exchange Shares, subject to the Beneficial Ownership Limitation effective at 8:00 a.m. (New York City time) on the day after the Effective Date.

Additionally, the Company agrees to the representations, warranties and covenants set forth on Annex A attached hereto and the Holder agrees to the representations, warranties and covenants set forth on Annex B attached hereto.

On or before 9:00 a.m. (New York City time) on the business day following the Effective Date, the Company shall file a Current Report on Form 8-K with the Securities and Exchange Commission disclosing all material terms of the transactions contemplated hereunder, including a form of this agreement as an exhibit thereto (“8-K Filing”). From and after the issuance of the 8-K Filing, the Company represents to the Holder that it shall not be in possession of any material, nonpublic information received from the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents that is not disclosed in the 8-K Filing. In addition, effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, on the one hand, and the Holder or any of its affiliates, on the other hand, shall terminate. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide the Holder with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the Effective Date without the express prior written consent of the Holder. To the extent that the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, delivers any material, non-public information to the Holder without the Holder’s consent, the Company hereby covenants and agrees that the Holder shall not have any duty of confidentiality with respect to, or a duty not to trade on the basis of, such material, non-public information.

The Company acknowledges and agrees that the obligations of the Holder under this letter agreement are several and not joint with the obligations of any other holder of Common Stock purchase warrants of the Company (each, an “Other Holder”) under any other agreement related to the amendment of the Purchase Agreements or the exchange of such warrants (each, an “Other Agreement”), and the Holder shall not be responsible in any way for the performance of the obligations of any Other Holder or under any such Other Agreement. Nothing contained in this letter agreement, and no action taken by the Holder pursuant hereto, shall be deemed to constitute the Holder and the Other Holders as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Holder and the Other Holders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this letter agreement and the Company acknowledges that the Holder and the Other Holders are not acting in concert or as a group with respect to such obligations or the transactions contemplated by this letter agreement or any Other Agreement. The Company and the Holder confirm that the Holder has independently participated in the negotiation of the transactions contemplated hereby with the advice of its own counsel and advisors. The Holder shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this letter agreement, and it shall not be necessary for any Other Holder to be joined as an additional party in any proceeding for such purpose.

The Company hereby represents and warrants as of the date hereof and covenants and agrees from and after the date hereof until 30 days following the Effective Date that none of the terms offered to any Other Holder with respect to any Other Agreement (or any amendment, modification or waiver thereof), is or will be more favorable to such Other Holder than those of the Holder and this letter agreement. If and whenever on or after the date hereof during the period described above, the Company enters into an Other Agreement , with more favorable terms, then (i) the Company shall provide notice thereof to the Holder promptly following the occurrence thereof and (ii) the terms and conditions of this letter agreement shall be, without any further action by the Holder or the Company, automatically amended and modified in an economically and legally equivalent manner such that the Holder shall receive the benefit of the more favorable terms and/or conditions (as the case may be) set forth in such Other Agreement (including the issuance of additional Exchange Shares or the issuance of new Common Stock purchase warrants to the Other Holder), including, without limitation, the same price discount and the same issuance of new warrants as in the Other Agreement, provided that upon written notice to the Company at any time the Holder may elect not to accept the benefit of any such amended or modified term or condition, in which event the term or condition contained in this letter agreement shall apply to the Holder as it was in effect immediately prior to such amendment or modification as if such amendment or modification never occurred with respect to the Holder. The provisions of this paragraph shall apply similarly and equally to each Other Agreement.

Except for (x) shares of Common Stock issuable by the Company to Other Holders pursuant to Other Agreements on terms substantially identical to the terms of this Agreement and (y) securities issuable pursuant to clause (b) of the definition of Exempt Issuance (as defined in the Purchase Agreements), from the date hereof until five Trading Days after the Effective Date, neither the Company nor any Subsidiary shall (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents, or (ii) file any registration statement or any amendment or supplement thereto.

Except as expressly set forth herein, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this letter agreement. The Company shall pay all transfer agent fees, stamp taxes and other taxes and duties levied in connection with the delivery of any Exchange Shares. This letter agreement shall be governed by the laws of the State of New York without regard to the principles of conflicts of law thereof.
