 (a) violate, conflict with or result in a
breach of any provision of or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination of, or accelerate the performance required by, or result in the creation of

 8.1 Financial Covenants. The Company hereby covenants to the Purchasers and the Collateral Agent as follows, which covenants shall
be based upon the Consolidated financial statements of the Company: 
  
 (a) Total Funded Debt to EBITDA Ratio. The Company will maintain at all times on the last day of each fiscal quarter a Total Funded Debt to EBITDA ratio, measured quarterly, of not greater than the following:

	  	3.5 to 1.0

  
 Notwithstanding the foregoing, if the

 9. Indemnification. 
  
 9.1 General Indemnification. The Company shall indemnify, defend and hold each Purchaser, its affiliates and their respective
officers, directors, partners (general and limited), employees, agents, trustees, advisors (including, without limitation, attorneys, accountants and financial advisors), attorneys-in-fact, successors and assigns (each a “Purchaser
Entity”) harmless from and against all Losses incurred or suffered by a Purchaser Entity as a result of, in connection with or related to the breach of any of the representations, warranties, covenants or agreements made by the Company in
this Agreement or any of the other Transaction Documents, except to the extent that such Losses are the result of the gross negligence, willful misconduct or fraud of such Purchaser Entity. Each Purchaser, severally and not jointly, shall indemnify,
defend and hold the Company, its affiliates, their respective officers, directors, employees, agents, attorneys, successors and assigns (each a “Company Entity”) harmless against all Losses as a result of the breach of any of the
representations, warranties, covenants or agreements made by such Purchaser in this Agreement or any of the other Transaction Documents, except to the extent that such Losses are a result of the gross negligence, willful misconduct or fraud of such
Company Entity.  
  
 9.2
Indemnification Principles. For purposes of this Section 9, “Losses” shall mean each and all of the following items: claims, losses (including, without limitation, losses of earnings), liabilities, obligations, payments,
damages (actual, punitive or consequential to the extent provided in this Section 9.2), charges, judgments, fines, penalties, amounts paid in settlement, costs, expenses (including, without limitation, interest which may be imposed in connection
therewith, costs and expenses of investigation, actions, suits, proceedings, demands, assessments and reasonable fees, expenses and disbursements of counsel, consultants and other experts) and diminution in values of the Securities from the date
hereof and only if the person making such a claim has sold such Securities prior to making such claim. Any payment (or deemed payment) by the Company to a Purchaser pursuant to this Section 9 shall be treated for federal income tax purposes as an
adjustment to the price paid by such Purchaser for its respective Note pursuant to this Agreement. Each Purchaser and the Company hereby agrees that Losses shall not include punitive or consequential damages except to the extent that such Losses are
the result of the gross negligence, willful misconduct or fraud of the party from whom the indemnification is being sought (the “Indemnifying Party”). 
  
 9.3 Claim Notice; Right to Defend. A party seeking indemnification (the “Indemnified
Party”) under this Section 9 shall promptly upon becoming aware of the facts indicating that a claim for indemnification may be warranted, give to the Indemnifying Party a claim notice relating to such Loss (a “Claim
Notice”). Each Claim Notice shall specify the nature of the claim, the applicable provision(s) of this Agreement or other instrument under which the claim for indemnity arises, and, if possible, the amount or the estimated amount thereof.
No failure or delay in giving a Claim Notice (so long as the same is given prior to  

  

 48 

 
expiration of the representation or warranty upon which the claim is based) and no failure to include any specific information relating to the claim (such as
the amount or estimated amount thereof) or any reference to any provision of this Agreement or other instrument under which the claim arises shall affect the obligation of the Indemnifying Party unless such failure materially and adversely
prejudices the Indemnifying Party. If such Loss relates to the commencement of any action or proceeding by a third person, the Indemnified Party shall give a Claim Notice to the Indemnifying Party regarding such action or proceeding and the
Indemnifying Party shall be entitled to participate therein to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After the delivery of notice from the Indemnifying Party to the Indemnified Party of its
election to assume the defense of such action or proceeding, the Indemnifying Party shall not be liable (except to the extent the proviso to this sentence is applicable, in which event it will be so liable) to the Indemnified Party under this
Section 9 for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation, provided that each Indemnified Party shall have the right to employ
separate counsel to represent it and assume its defense (in which case, the Indemnifying Party shall not represent it) if (i) upon the advice of counsel, the representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them, (ii) in the event the Indemnifying Party has not assumed the defense thereof within 10 days of receipt of notice of such claim or commencement of action, and in which case the fees and expenses of one such
separate counsel shall be paid by the Indemnifying Party or (iii) if such Indemnified Party who is a defendant in any action or proceeding which is also brought against the Indemnifying Party reasonably shall have concluded that there may be one or
more legal defenses available to such Indemnified Party which are not available to the Indemnifying Party. If any Indemnified Party employs such separate counsel it will not enter into any settlement agreement which is not approved by the
Indemnifying Party, such approval not to be unreasonably withheld. If the Indemnifying Party so assumes the defense thereof, it may not agree to any settlement of any such claim or action as the result of which any remedy or relief, other than
monetary damages for which the Indemnifying Party shall be responsible hereunder, shall be applied to or against the Indemnified Party, without the prior written consent of the Indemnified Party. In any action hereunder as to which the Indemnifying
Party has assumed the defense thereof with counsel reasonably satisfactory to the Indemnified Party, the Indemnified Party shall continue to be entitled to participate in the defense thereof, with counsel of its own choice, but, except as set forth
above, the Indemnifying Party shall not be obligated hereunder to reimburse the Indemnified Party for the costs thereof. 
  
 9.4 Limitations on Indemnification. Other than with respect to any indemnification claim made with respect to Losses arising from a
claim, action or proceeding by a third Person pursuant to this Section 9, for which indemnification obligations hereunder shall be unlimited, neither Company nor any Purchaser shall have any indemnification payment obligations with respect to
Section 9.1 for Losses in excess of the aggregate Purchase Price paid for the Shares and Notes sold under this Agreement. 
  
 9.5 Subrogation. Upon making an indemnity payment pursuant to this Agreement, the Indemnifying Party will, to the extent of such
payment, be subrogated to all rights of the Indemnified Party against any third Person in respect of the Losses to which the payment related. Without limiting the generality of any other provision hereof, each such  

  

 49 

 
Indemnified Party and Indemnifying Party will duly execute upon request all instruments reasonably necessary to evidence and perfect the above-described
subrogation rights. 
  
 9.6 No Double
Recovery; Use of Insurance. Notwithstanding anything herein to the contrary, neither Company nor any Purchaser shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such party or
any Affiliate has been indemnified or reimbursed for such amount under any other provision of this Agreement or any other Transaction Document. Furthermore, in the event any Losses related to a claim by an Indemnified Party are covered by insurance,
the Indemnified Party agrees to use commercially reasonable efforts to seek recovery under such insurance and the Indemnified Party shall refund to the Indemnifying Party amounts of insurance actually received up to the amount of indemnification
payments actually received with respect to such Losses to the extent the Indemnified Party recovers from the insurance. 
  
 9.7 Mitigation. The Company and each Purchaser each agrees to use reasonable efforts to mitigate any Loss which forms the basis of
a claim under this Section 9.

 15.16
Confidentiality. The Collateral Agent and each Purchaser agree that it will not disclose without the prior written consent of the Company (other than to its employees, its Affiliates, to the Collateral Agent or another Purchaser or to its
auditors or counsel who have a legitimate need to receive such information) any information with respect to the Company and its Subsidiaries, which is furnished to a Purchaser in such Purchaser’s capacity as an investor in the Company (but not
in such Purchaser’s capacity as director, if applicable) pursuant to this Agreement or any of the Transaction Documents; provided, that the Collateral Agent and any Purchaser may disclose such information (a) as has generally become available
to the public or has been lawfully obtained by the Collateral Agent or such Purchaser from any third party under no duty of confidentiality to the Company, (b) as may be required in any report, statement or testimony submitted to, or in respect to
any inquiry, by, any municipal, state or federal regulatory body having or claiming to have jurisdiction over such Purchaser, including the Board of Governors of the Federal Reserve System of the United States, the Office of the Comptroller of the
Currency or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors (provided the Company is given reasonable prior written notice of such disclosure to the extent reasonably
practicable), (c) as may be required in respect to any summons or subpoena or in connection with any litigation or arbitration (provided the Company is given reasonable prior written notice of such disclosure to the extent reasonably practicable),
(d) in order to comply with any law, order regulation or ruling applicable to such Purchaser (provided the Company is given reasonable prior written notice of such disclosure to the extent reasonably practicable), and (e) to any permitted transferee
or assignee or to any approved participant of, or with respect to, the Securities. If the transactions contemplated hereby are not consummated for any reason, each Purchaser shall return to the Company, without retaining any copies thereof, any
schedules, documents or other written 

  

 69 

 
information obtained from the Company in connection with this Agreement and the transactions contemplated hereby and shall cause all of its representatives
to whom it may have disclosed such information to do the same. 
  
 15.17 Break-Up Fee. (a) (a) In the event that the Company is unable to consummate the transactions contemplated in Section 1.3 hereof on the First Closing Date due to a determination by the board of directors
of the Company that the consummation of such transactions conflict with its exercise of its fiduciary duties under applicable Law including, without limitation, the Delaware General Corporation Law, the Company shall pay to the Purchasers a
“break-up” fee in the amount of two hundred and fifty thousand dollars ($250,000) (the “Break Up Fee”); provided, however, that if the transactions contemplated in Section 1.3(a) are not consummated because the acquisition
of Beta Analytics, Incorporated is not consummated by the Company as a result of the exercise by the Company of its rights to terminate its agreement to acquire such company due to a material adverse change in the condition of such company, the
Break Up Fee shall not be payable hereunder. The Break Up Fee shall by paid by the Company to the Purchasers by certified check, made payable to each Purchaser, or wire transfer of immediately available funds to such account as each Purchaser
designates, in an amount equal to each Purchaser’s pro rata share based on the Purchase Price paid by such Purchaser at the First Closing as compared with the Purchase Price paid by all of the Purchasers at the First Closing (“Pro Rata
Share”) of the Break Up Fee. If the Purchasers are unable to consummate the transactions contemplated in Section 1.3(a) on the First Closing Date for any reason other than as a result of the failure of the Company to comply with its
obligations hereunder or to satisfy the closing conditions set forth in Section 5.1, each Purchaser shall pay to the Company its Pro Rata Share of the Break Up Fee. The Break Up Fee referenced in the immediately preceding sentence shall by paid by
the Purchasers to the Company by certified check, made payable to the Company, or wire transfer of immediately available funds to such account as the Company designates. 
  
 (b) The Company and the Purchasers agree that if the Break Up Fee is payable hereunder, the right of the
Company or the Purchasers, as the case may be, to receive such amount shall constitute the sole and exclusive remedy for, and such amount shall constitute liquidated damages in respect of, termination of this Agreement regardless of the
circumstances giving rise to such termination. 
  
 15.18 Termination. This Agreement shall terminate on the date of termination of the Company’s agreement to purchase Beta Analytics, Incorporated. This Agreement may be terminated at any time prior to the Closing by mutual
agreement of the Company and all Purchasers set forth in writing. Each provision hereof expressly stated to survive the termination shall survive the termination of this Agreement. 
  
 15.19 Most Favored Nations. If the Company refinances or renegotiates its Senior Credit Facility so
that one or more of the covenants set forth in Section 7 or Section 8 of this Agreement are more restrictive upon the Company than any covenant(s) set forth in the Senior Credit Facility (each, a “Restrictive Covenant”), then,
notwithstanding anything to the contrary in this Agreement (including Section 15.8) or in any of the other Transaction Documents, each Purchaser hereby agrees to amend this Agreement so that the Restrictive Covenant(s) are replaced with covenants
that are the same as those set forth in such Senior Credit Facility as refinanced or renegotiated. In connection with and prior to any such amendment to this Agreement, the Company shall provide each Purchaser with a copy of the new Senior Credit
Facility and the amendment to this Agreement. Thereafter, so long as such Senior Credit Facility is approved by the Board of Directors, such amendment to this Agreement which will be effective whether or not signed by the Purchasers.
