 2. Subordination.  

2.1 Subordination of Subordinated Debt to Senior Debt. The Company covenants and agrees, and Subordinated Creditor by its
execution hereof or its acceptance of the Purchase Agreements and any Subordinated Notes (whether upon original issue or upon transfer or assignment) likewise covenants and agrees, notwithstanding anything to the contrary contained in any of the
Subordinated Debt Documents, that the payment of any and all of the Subordinated Debt shall be subordinate and subject in right and time of payment, to the extent and in the manner set forth in this Agreement, to the prior indefeasible payment in
full (other than inchoate indemnity obligations) in cash of all Senior Debt. Each holder of Senior Debt, whether such Senior Debt is now outstanding or hereafter created, incurred, assumed or guaranteed, shall be deemed to have acquired Senior Debt
in reliance upon the provisions contained in this Agreement. Notwithstanding the terms of the Subordinated Debt Documents, the Company hereby agrees that it will not make, and Subordinated Creditor hereby agrees that it will not accept, any
Distribution, whether in cash, securities or other property, with respect to or as payment for the Subordinated Debt until the Subordination Termination Date; provided however that the Company may issue to the Subordinated Creditor, and the
Subordinated Creditor may accept, Series A Preferred Stock in the amounts and on the conditions set forth in the Subordinated Notes in connection with a Subordinated Debt Conversion. 

2.2 Liquidation, Dissolution, Bankruptcy. In the event of any Proceeding involving the Company: 

(a) The Company shall not make and Subordinated Creditor shall not receive any Distribution, whether in cash, securities or
other property, on account of or as payment for any Subordinated Debt prior to the Subordination Termination Date. 

(b) Any Distribution, whether in cash, securities or other property which would otherwise, but for the terms
hereof, be payable or deliverable in respect of the Subordinated Debt shall be paid or delivered directly to Senior Creditor Agent (to be held and/or applied by Senior Creditor Agent in accordance with the terms of the Senior Debt Documents) until
the Subordination Termination Date. Subordinated Creditor irrevocably authorizes, empowers and directs any debtor, debtor-in-possession, receiver, trustee, liquidator,
custodian, conservator or other Person having authority, to pay or otherwise deliver all such Distributions to Senior Creditor Agent. Subordinated Creditor also irrevocably authorizes and empowers Senior Creditor Agent, in the name of Subordinated
Creditor, to demand, sue for, collect and receive any and all such Distributions and other amounts owing under the Subordinated Debt Documents. 

(c) Subordinated Creditor agrees not to initiate, prosecute or participate in any claim, action or other proceeding challenging
the enforceability, validity, perfection or priority of the Senior Debt or any liens and security interests securing the Senior Debt. 

(d) Subordinated Creditor agrees that Senior Creditor Agent and Senior Creditor may consent to the use of cash collateral or
provide financing (including debtor-in-possession 

  
 4 








 
financing) to the Company on such terms and conditions and in such amounts as Senior Creditor Agent and Senior Creditor, in their sole discretion, may decide and, in connection therewith, the
Company may grant to Senior Creditor Agent and Senior Creditor liens and security interests upon all of the property of the Company, which liens and security interests (i) shall secure payment of all Senior Debt (whether such Senior Debt arose
prior to the commencement of any Proceeding or at any time thereafter) and all other financing provided by Senior Creditor Agent and Senior Creditor during such Proceeding and (ii) shall be superior in priority to the liens and security
interests, if any, in favor of Subordinated Creditor on the property of the Company. Subordinated Creditor agrees that it will not object to or oppose a sale or other disposition of any property securing all or any part of the Senior Debt free and
clear of security interests, liens or other claims of Subordinated Creditor under Section 363 of the Bankruptcy Code or any other provision of the Bankruptcy Code if Senior Creditor Agent or Senior Creditor has consented to such sale or
disposition. Subordinated Creditor agrees not to assert any right it may have to “adequate protection” of Subordinated Creditor’s interest in any Collateral or any other assets of the Company in any Proceeding and agrees that it will
not seek to have the automatic stay lifted with respect to any Collateral or any other assets of the Company without the prior written consent of Senior Creditor Agent. Subordinated Creditor waives any claim it may now or hereafter have arising out
of Senior Creditor Agent’s or Senior Creditor’s election, in any Proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b)(2) of the Bankruptcy Code, and/or any borrowing or grant of a security interest
under Section 364 of the Bankruptcy Code by the Company, as debtor-in-possession. Subordinated Creditor further agrees that it will not participate or seek to participate on any creditor’s committee without Senior Creditor Agent’s
prior written consent. 
 (e) Subordinated Creditor agrees to execute, verify, deliver and file any proofs of claim in
respect of the Subordinated Debt requested by Senior Creditor Agent in connection with any such Proceeding and hereby irrevocably authorizes, empowers and appoints Senior Creditor Agent its agent and attorney-in-fact to (i) execute, verify,
deliver and file such proofs of claim upon the failure of Subordinated Creditor promptly to do so prior to 30 days before the expiration of the time to file any such proof of claim and (ii) vote the full amount of such claim in any such
Proceeding; provided that Senior Creditor Agent shall have no obligation to execute, verify, deliver, file and/or vote any such proof of claim or claim. In the event that Senior Creditor Agent votes any claim in accordance with the authority
granted hereby, Subordinated Creditor shall not be entitled to change or withdraw such vote. 
 (f) The Senior Debt shall
continue to be treated as Senior Debt and the provisions of this Agreement shall continue to govern the relative rights and priorities of Senior Creditor Agent, Senior Creditor and Subordinated Creditor even if all or part of the Senior Debt or the
security interests securing the Senior Debt are subordinated, set aside, avoided, invalidated, or disallowed in connection with any such Proceeding, and this Agreement shall be reinstated if at any time any payment of any of the Senior Debt is
rescinded or must otherwise be returned by any holder of Senior Debt or any representative of such holder. 
 2.3 Subordinated Debt
Standstill Provisions. Until the Subordination Termination Date, Subordinated Creditor (or any of them) shall not, without the prior written consent of Senior Creditor Agent, take any Enforcement Action with respect to the
Subordinated Debt or any Collateral or other assets of the Company; provided that Subordinated Creditor may exercise any rights it (or any of them) may have solely in their capacity as equityholders of the Company in a manner not inconsistent
with the other terms of this Agreement. Any Distributions or other proceeds of any Enforcement Action obtained by Subordinated Creditor in violation of the immediately preceding sentence shall in any event be held in trust by it for the benefit of
Senior Creditor Agent and Senior Creditor and promptly paid or delivered to Senior Creditor Agent in the form received. 

  
 5 








 2.4 Incorrect Payments and Payover. Until the Subordination Termination
Date, if any Distribution on account of or as payment for the Subordinated Debt that is not permitted to be made by the Company or accepted by Subordinated Creditor under this Agreement is nonetheless made or received by Subordinated Creditor, such
Distribution shall not be commingled with any of the assets of Subordinated Creditor, shall be held in trust by Subordinated Creditor for the benefit of Senior Creditor Agent and Senior Creditor and shall be promptly paid over to Senior Creditor
Agent for application (in accordance with the Senior Debt Documents) to the payment of the Senior Debt then remaining unpaid. 
 2.5
Subordination of Liens and Security Interests; Agreement Not to Contest; Agreement to Release Liens; Acknowledgement of Liens. 

(a) Until the Subordination Termination Date, all liens and security interests of Subordinated Creditor (or any of them) in the
Collateral and any other assets of the Company shall be and hereby are subordinated for all purposes and in all respects to the liens and security interests of Senior Creditor Agent in the Collateral and any other assets of the Company, regardless
of the validity, enforceability, avoidance, dispute, unperfection, or the time, method, manner or order of the grant, attachment, filing or perfection of any such liens and security interests, any provision of the Uniform Commercial Code, the
Bankruptcy Code, any Senior Debt Document or any Subordinated Debt Document or any other circumstance whatsoever until the Subordination Termination Date. Subordinated Creditor agrees that it will not at any time contest the validity, perfection,
priority or enforceability of the Senior Debt, the Senior Debt Documents, or the liens and security interests of Senior Creditor Agent in the Collateral or any other assets of the Company securing the Senior Debt. In the event that Senior Creditor
Agent releases or agrees to release any of its liens or security interests in the Collateral or any other assets of the Company in connection with the sale or other disposition thereof, or if any of the Collateral or any other assets of the Company
is sold or retained pursuant to a foreclosure or similar action, Subordinated Creditor agrees that its liens or security interests in such Collateral and other assets of the Company, if any, shall automatically be released, and Subordinated Creditor
shall (or shall cause its agent to) promptly execute and deliver to Senior Creditor Agent or authorize Senior Creditor Agent to file such termination statements and releases as Senior Creditor Agent shall reasonably request to effect the release of
the liens and security interests of Subordinated Creditor in such Collateral or other assets of the Company. In furtherance of the foregoing, Subordinated Creditor hereby irrevocably appoints Senior Creditor Agent its attorney-in-fact, with full
authority in the place and stead of Subordinated Creditor and in the name of Subordinated Creditor or otherwise, to execute and deliver any document or instrument which Subordinated Creditor may be required to deliver pursuant to this
Section 2.5. 
 (b) The Subordinated Creditor acknowledges, consents and agrees that Senior Creditor Agent has been
granted first-priority liens upon and security interests in the Collateral for the benefit of Senior Creditor Agent and Senior Creditor. The Subordinated Creditor agrees that it shall not obtain a lien on or security interest in any property of the
Company to secure all or any portion of the Subordinated Debt unless, concurrently therewith, Senior Creditor Agent obtains a first priority lien on and security interest in such asset or collateral, and the parties hereby agree that all such liens
and security interests are and will be subject to this Agreement. The Subordinated Creditor agrees that it shall not obtain any control agreement with respect to any deposit account, securities account or other property of the Company without the
prior written consent of Senior Creditor Agent.

 2.6 Application of Proceeds from Sale or other Disposition of the
Collateral. Until the Subordination Termination Date, in the event of any sale, transfer, lease, license or other disposition (including a casualty loss or taking through eminent domain) of the Collateral or any other asset of the
Company, the proceeds resulting therefrom (including proceeds from insurance or any other Enforcement Action by any party hereto) shall be applied in accordance with the terms of the Senior Debt Documents or as otherwise consented to by Senior
Creditor Agent. 
 2.7 Sale, Transfer or other Disposition of Subordinated Debt.  

(a) Subordinated Creditor shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the
Subordinated Debt or any Subordinated Debt Document other than the disposal of the Subordinated Debt in connection with the Subordinated Debt Conversion. 

(b) Notwithstanding the foregoing subsection 2.7(a), the debt and lien subordination effected by this Agreement shall survive
any sale, assignment, pledge, disposition or other transfer of all or any portion of the Subordinated Debt in violation of the terms of subsection 2.7(a), and the terms of this Agreement shall be binding upon the successors and assigns of
Subordinated Creditor, as provided in Section 10 hereof. 
 2.8 Legends. Until the Subordination Termination Date,
Subordinated Creditor will cause to be clearly, conspicuously and prominently inserted on the face of the Subordinated Notes and any other Subordinated Debt Document, as well as any renewals or replacements thereof, the following legend: 

“This instrument and the indebtedness, rights and obligations evidenced hereby and any liens or other security interests
securing such rights and obligations are subordinate in the manner and to the extent set forth in that certain Subordination and Intercreditor Agreement (as amended, restated, supplemented or modified from time to time, the “Subordination
Agreement”) dated as of May 12, 2015, by and among the Subordinated Creditors identified therein and General Electric Capital Corporation in its capacity as agent for certain lenders (together with its successors and assigns, “Senior
Creditor Agent”), to certain indebtedness, rights, and obligations of BG MEDICINE, INC. to Senior Creditor Agent and Senior Creditor (as defined therein) and liens and security interests in favor of Senior Creditor Agent securing the same all
as described in the Subordination Agreement; and each holder and transferee of this instrument, by its acceptance hereof, irrevocably agrees to be bound by the provisions of the Subordination Agreement.” 

3. Modifications.  
 3.1
Modifications to Senior Debt Documents. Senior Creditor Agent or Senior Creditor may at any time and from time to time without the consent of or notice to Subordinated Creditor, without incurring liability to Subordinated Creditor and
without impairing or releasing the obligations of Subordinated Creditor under this Agreement, change the manner or place of payment or extend the time of payment of or renew or alter any of the terms of the Senior Debt, or amend in any manner any
Senior Debt Document, including without limitation to increase the Senior Debt.

Subordinated Creditor is not waiving, and shall not be deemed to have waived, any rights that Subordinated Creditor has as a stockholder of the Company, including any voting, consent or information rights. Moreover, nothing contained herein shall be
deemed to be a waiver of, and the Subordinated Creditor is not waiving, any notice obligations that the Company has to the Subordinated Creditor. 

4.2 Marshaling. Subordinated Creditor hereby waives any rights it may have under applicable law to assert the doctrine of
marshaling or to otherwise require Senior Creditor Agent to marshal any property of the Company or any guarantor of the Senior Debt for the benefit of Subordinated Creditor. 

4.3 Rights Relating to Senior Creditor Agent’s Actions with respect to the Collateral. 

(a) Subordinated Creditor hereby waives, to the extent permitted by applicable law, any rights which it may have to enjoin or
otherwise obtain a judicial or administrative order preventing Senior Creditor Agent and/or Senior Creditor from taking, or refraining from taking, any action with respect to all or any part of the Collateral or any other assets of the Company.
Without limitation of the foregoing, Subordinated Creditor hereby agrees (a) that it has no right to direct or object to the manner in which Senior Creditor Agent and/or Senior Creditor applies the proceeds of the Collateral or any other assets

limitation, the rights to sell or otherwise dispose of Collateral or any other assets of the Company, to incur expenses in connection with such sale or disposition and to exercise all the rights and remedies of a secured lender under the Uniform
Commercial Code of any applicable jurisdiction. In conducting any public or private sale under the Uniform Commercial Code, Senior Creditor Agent shall give the Subordinated Creditor such notice of such sale only to the extent required by the
applicable Uniform Commercial Code; provided, however, that if such notice is required to be given, 10 days’ notice shall be deemed to be commercially reasonable notice. The Subordinated Creditor agrees that neither Senior
Creditor Agent nor Senior Creditor shall incur any liability as

directors, officers, employees, or agents shall be liable for failure to demand, collect, or realize upon any of the Collateral or any proceeds thereof or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral or proceeds thereof or to take any other action whatsoever with regard to the Collateral or any part or proceeds thereof. If Senior Creditor Agent or Senior Creditor should act upon, omit to act upon, or exercise any of their contractual
rights or remedies under the Senior Debt Documents (subject to the express terms and conditions hereof), neither Senior Creditor Agent nor Senior Creditor shall have any liability whatsoever to the Subordinated Creditor as a result of such action,
omission, or exercise. 
 4.4 Additional Rights of Senior Creditor Agent and Senior Creditor. Senior Creditor Agent and Senior
Creditor will be entitled to manage and supervise the loans and extensions of credit under the Senior Debt Documents as Senior Creditor Agent and Senior Creditor may, in their sole discretion, deem appropriate, and Senior Creditor Agent and Senior
Creditor may manage their loans and extensions of credit without regard to any rights or interests that the Subordinated Creditor may have in the Collateral or any other assets of the Company or otherwise. Senior Creditor Agent, Senior Creditor and
each holder of Senior Debt may, from time to time, enter into agreements and settlements with the Company or other parties to the Senior Debt Documents as it may determine in its sole discretion without impairing any of the subordinations,
priorities, rights or obligations of the parties under this Agreement, including substituting collateral and releasing any lien on any Collateral or any other asset of the Company.

rights to assert against Senior Creditor Agent or Senior Creditor any defense (legal or equitable), set-off, counterclaim, or claim which Subordinated Creditor may now or at any time hereafter have against the Company, any other holder of Senior
Debt, any other party liable to Senior Creditor Agent or Senior Creditor, or any Person constituting Subordinated Creditor; (b) any defense, set-off, counterclaim, or claim, of any kind or nature, arising directly or indirectly from the present
or future lack of perfection, sufficiency, validity, or enforceability of any Senior Debt, any Subordinated Debt or any security for either; (c) any defense arising by reason of any claim or defense based upon an election of remedies by Senior
Creditor Agent or Senior Creditor; and (d) the benefit of any statute of limitations affecting the obligations of Subordinated Creditor hereunder or the enforcement thereof, and any act which shall defer or delay the operation of any statute of
limitations applicable to the Senior Debt shall similarly operate to defer or delay the operation of such statute of limitations applicable to such obligations of the Subordinated Creditor hereunder.

between the Company and Subordinated Creditor, a payment by the Company to or on account of the Senior Debt. WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER PROVISION SET FORTH IN THIS AGREEMENT, SUBORDINATED CREDITOR HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS AND DEFENSES ARISING OUT OF AN ELECTION OF REMEDIES BY SENIOR CREDITOR AGENT OR SENIOR CREDITOR, EVEN THOUGH THAT ELECTION OF REMEDIES HAS DESTROYED SUBORDINATED CREDITOR’S RIGHTS OF SUBROGATION
AND REIMBURSEMENT AGAINST THE COMPANY BY THE OPERATION OF ANY APPLICABLE LAW. 
 7. Modification. Any modification or waiver of any provision
of this Agreement, or any consent to any departure by any party from the terms hereof, shall not be effective in any event unless the same is in writing and signed by Senior Creditor Agent and Subordinated Creditor, and then such modification,
waiver or consent shall be effective only in the specific instance and for the specific purpose given. Any notice to or demand on any party hereto in any event not specifically required hereunder shall not entitle the party receiving such notice or
demand to any other or further notice or demand in the same, similar or other circumstances unless specifically required hereunder. 
 8. Further
Assurances. Each party to this Agreement promptly will execute and deliver such further instruments and agreements and do such further acts and things as may be reasonably requested in writing by any other party hereto that may be necessary
or desirable in order to effect fully the purposes of this Agreement.

this Agreement is deemed to be invalid, illegal or unenforceable by reason of the operation of any law or by reason of the interpretation placed thereon by any court or governmental authority, the validity, legality and enforceability of the
remaining provisions of this Agreement shall not in any way be affected or impaired thereby, and the affected provision shall be modified to the minimum extent permitted by law so as most fully to achieve the intention of this Agreement.
