If the Parties resolve such differences, the Closing Working Capital Amount agreed to by the Parties shall be deemed to be the “ Final Closing Working Capital Amount ” and the Closing Working Capital Statement agreed to by the Parties shall be deemed to be the “ Final Closing Working Capital Statement .”

(c) If the Parties do not reach a final resolution on the Closing Working Capital Amount within forty-five (45) days after Buyer has delivered the Dispute Notice, unless the Parties mutually agree in writing to continue their efforts to resolve such differences, Grant Thornton LLP (the “ Neutral Accountant ”) shall resolve such differences, pursuant to an engagement agreement executed by the Parties and the Neutral Accountant, in the manner provided below. The Parties shall each be entitled to make a presentation to the Neutral

- 14 -

Accountant, pursuant to procedures to be agreed to among PKI, Buyer and the Neutral Accountant (or, if they cannot agree on such procedures, pursuant to procedures determined by the Neutral Accountant), regarding such Party’s calculation of the Closing Working Capital Amount. The Neutral Accountant shall be required to resolve the differences between the Parties and determine the Closing Working Capital Amount within twenty (20) Business Days thereafter and, upon reaching such determination, the Neutral Accountant shall deliver a written copy of its determination, which shall state in reasonable detail the findings of fact on which it is based, to PKI and Buyer. The Closing Working Capital Amount determined by the Neutral Accountant shall be deemed to be the Final Closing Working Capital Amount and the Closing Working Capital Statement, as adjusted to reflect such determination, shall be deemed to be the Final Closing Working Capital Statement. Such determination by the Neutral Accountant shall be conclusive and binding upon the Parties, absent fraud or manifest error.

(d) The Neutral Accountant shall not be authorized or permitted to:

(i) determine any questions or matters whatsoever under or in connection with this Agreement except for the resolution of differences between the Parties regarding the determination of the Closing Working Capital Amount in accordance with this Section 1.4 ;

(ii) resolve any such differences by making an adjustment to the Closing Working Capital Statement that is outside the range of values assigned to a particular disputed item as finally proposed by the Parties; or

(iii) apply any accounting methods, treatments, principles or procedures other than as described in Schedule 1.4(a) .

(e) PKI and Buyer shall each pay one half of the fees and expenses of the Neutral Accountant; provided that if the Neutral Accountant determines that one Party has adopted a position or positions with respect to the Closing Working Capital Statement that is frivolous or clearly without merit, the Neutral Accountant (i) may, in its discretion, assign a greater portion of any such fees and expenses to such Party and (ii) shall provide to the Parties a written explanation of its reasons for making such a determination in the event that it does so.

(f) The Parties agree that the procedure set forth in this Section 1.4 for resolving disputes with respect to the Closing Working Capital Amount shall be the sole and exclusive method for resolving any such disputes, provided that this provision shall not prohibit either Party from instituting litigation to enforce the ruling of the Neutral Accountant.

(g) Failure of Buyer to deliver a Dispute Notice within forty-five (45) days after receiving the Closing Working Capital Statement shall constitute acceptance of the Closing Working Capital Amount set forth on the Closing Working Capital Statement, whereupon such Closing Working Capital Amount shall be deemed to be the Final Closing Working Capital Amount and the Closing Working Capital Statement shall be deemed to be the Final Closing Working Capital Statement. Delivery by Buyer of a Dispute Notice shall constitute final and binding acceptance by Buyer of all portions of the Closing Working Capital Statement other than those specifically identified in the Dispute Notice as being subject to a good faith dispute.

Subject to the third sentence of this Section 1.4(h) , if the Final Closing Working Capital Amount is more than the Target Working Capital Amount, then Buyer shall pay to PKI an amount equal to the difference between the Final Closing Working Capital Amount and the Target Working Capital Amount. Notwithstanding anything to the contrary contained in this Agreement, if the Final Closing Working Capital Amount is between $35,668,000 and $37,668,000, no payment shall be due under this Section 1.4(h) or otherwise with respect to the adjustment contemplated by Section 1.4 .

1.5 Consents to Assignment . Anything in this Agreement to the contrary notwithstanding, except as otherwise provided in any applicable Local Transfer Agreement, this Agreement shall not constitute an agreement to assign or transfer any agreement, lease, authorization, license or permit, or any claim, right or benefit arising thereunder or resulting therefrom, if an attempted assignment or transfer thereof, without the consent of a third party thereto or of the issuing Governmental Entity (as defined in Section 2.4(b) ), as the case may be, would constitute a breach or default thereof, would result in a violation of the rights of any such third party, would be ineffective, or would in any way adversely affect the rights of PKI or Buyer thereunder. If such consent (a “ Deferred Consent ”) is not obtained, then (a) the agreement, lease, authorization, license or permit to which such Deferred Consent relates (each, a “Deferred Item” and any such deferred agreement or lease, a “ Deferred Contract ”) shall not be assigned or transferred pursuant to this Agreement, and there shall be no reduction in the Purchase Price as a result thereof, (b) from and after the Closing, the Sellers and Buyer will cooperate, in all reasonable respects, to obtain such Deferred Consent as soon as practicable after the Closing, provided that no Seller or Buyer shall be required to make any payments or agree to any material undertakings in connection therewith, and (c) until such Deferred Consent is obtained, the Sellers and Buyer shall cooperate, in all reasonable respects, in any lawful and commercially reasonable arrangement reasonably proposed by Buyer under which (i) Buyer would obtain (without infringing upon the legal rights of any third party) the economic claims, rights and benefits (net of the amount of any related Tax costs and any other liabilities or obligations imposed on the Sellers or any of their Affiliates) under the Deferred Item and (ii) Buyer would assume any related economic burden (including the amount of any related Tax costs and any other liabilities or obligations imposed on the Sellers or any of their Affiliates) with respect to the Deferred Item.

1.7 Right to Withhold . Buyer and its Affiliates shall be entitled to deduct and withhold from any amounts otherwise deliverable or payable under this Agreement as may be required to be deducted or withheld with respect to the making of such payment under any applicable law. To the extent that any amounts are so deducted or withheld and paid over to the appropriate Governmental Entity, the deducted or withheld amounts shall be treated for all purposes under this Agreement as having been paid to the person or entity in respect of which such deduction or withholding was required.

(e) For purposes of this Agreement:

(i) “ Buyer Willful Breach ” means the breach by Buyer of a covenant or obligation of Buyer under this Agreement where: (A) such covenant or obligation is material to the ability of Buyer to timely consummate the transactions contemplated by this Agreement or

(a) PKI shall be responsible for the preparation and filing of all Tax Returns for Sellers for all periods (including the consolidated, unitary and combined Tax Returns for Sellers, which include the operations of the Business for any period ending on or before the Closing Date) and for all Tax Returns of the Acquired Companies for all taxable periods that end on or before the Closing Date. Sellers shall make or cause to be made all payments required with respect to any such Tax Returns. Buyer shall promptly reimburse Sellers for the amount of any such Taxes paid by Sellers to the extent such Taxes, if any, are attributable (as determined under Section 8.2 hereof) to periods following the Closing Date or were included as an accrual, reserve or provision reflected in the Final Working Capital Statement. Any Tax Return that is the responsibility of PKI under this Section 8.1(a) for which Buyer may be obligated to reimburse Seller hereunder or that is a separate Tax Return required to be filed after the Closing Date shall be prepared on a basis consistent with the last previous similar Tax Return, and PKI shall consult with Buyer concerning each such Tax Return in good faith.

(b) Buyer shall be responsible for the preparation and filing of all other Tax Returns for the Business that are required to be filed after the Closing Date with respect to taxable periods ending on or including the Closing Date. Buyer shall make all payments required with respect to any such Tax Returns; provided , however , that PKI shall promptly reimburse Buyer for the amount of any such Taxes to the extent such Taxes are attributable (as determined under Section 8.2 for any taxable period beginning before the Closing Date and ending after the Closing Date) to periods or portions thereof ending on or before the Closing Date, except to the extent the amount of such Taxes was included as an accrual, reserve or provision reflected in the Final Working Capital Statement.

- 69 -

(c) Any Tax Return to be prepared and filed by Buyer for taxable periods ending on or including the Closing Date shall be prepared on a basis consistent with the last previous similar Tax Return, and Buyer shall consult with PKI concerning each such Tax Return in good faith; provided , however , that if Buyer is advised by counsel or otherwise determines in good faith after consultation with PKI that the filing of any such Tax Return and the reporting on such Tax Return in accordance with the last previous similar Tax Return is likely to subject Buyer to any penalties or is otherwise inconsistent with applicable law, Buyer may file such Tax Return without regard to last previous similar Tax Return relating to such item. Buyer shall provide PKI with a copy of each proposed draft of any such Tax Return (and such additional information regarding such Tax Return as may reasonably be requested by PKI) at least thirty (30) days prior to the filing of such Tax Return.

Any Taxes for a taxable period beginning before the Closing Date and ending after the Closing Date shall be apportioned for purposes of this Agreement based on a hypothetical closing of the books as of the close of the Closing Date; provided, however, that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending at the close of the Closing Date and the period subsequent to the Closing Date in proportion to the number of days in each such period. Notwithstanding the foregoing, property, ad valorem and similar Taxes attributable to a taxable period beginning before the Closing Date and ending after the Closing Date shall be allocated between such two periods in proportion to the number of days in each such period.

Buyer shall have the right, at its own expense, to control any other Tax Audit, initiate any other claim for refund, and initiate any other contest, resolve and defend against any other assessment, notice of deficiency, or other adjustment or proposed adjustment relating to Taxes with respect to the Acquired Companies or the Business; provided that, with respect to (i) any state, local or foreign Taxes for any taxable period beginning before the Closing Date and ending after the Closing Date and (ii) any item the adjustment of which may cause the Sellers to become obligated to make any payment pursuant to Section 8.1 or otherwise have an indemnification obligation, Buyer shall consult with PKI with respect to the resolution of any issue that would affect any Seller, and not settle any such issue, or file any amended Tax Return relating to such issue, without the consent of PKI, which consent shall not be unreasonably conditioned or delayed.

8.5 Termination of Tax Sharing Agreements . All Tax sharing agreements or similar arrangements with respect to or involving the Business shall be terminated on or prior to the Closing Date and, after the Closing Date, Buyer and its Affiliates shall not be bound thereby or have any liability thereunder for amounts due in respect of periods ending on or before the Closing Date.

Where a Party to this Agreement or any of its Affiliates makes a supply of goods or services to the other Party or its Affiliates and the supplier is obliged by law or due to the exercise of an option available under applicable law to account for VAT in respect of that supply then the recipient of that supply shall, in addition to the consideration payable for such supply, pay an amount equal to the legally or due to the option owed VAT (if any) arising in respect of such supply after receipt of a valid and proper VAT invoice. No such amount of VAT is payable by the recipient of the supply to the supplier if and to the extent that a Party to this Agreement or any of its Affiliates makes a supply of goods or services to the other Party that is treated as a reverse charge supply. In this case, the recipient of the supply shall be responsible for full and timely payment of all VAT legally owed in respect of the relevant supply.

- 72 -

(c) The Parties acknowledge and are of the common opinion that (i) the sale and transfer of the Acquired Assets and the Assumed Liabilities by the Asset Sellers pursuant to this Agreement qualify as a transfer of a going concern (“ TOGC ”), (ii) the buyers of the Acquired Assets have the intention of carrying on the same business with the Acquired Assets as the Asset Sellers, and (iii) therefore, no VAT should apply to the sale and transfer of Acquired Assets and the Assumed Liabilities. In this regard, Buyer covenants that the buyers of the Acquired Assets (A) are or will be at the Closing Date registered for VAT and taxable persons for VAT purposes and (B) intend to carry on the business in the same manner as the Asset Seller and not simply to immediately liquidated it.

(d) In the event that, contrary to the Parties’ assumption, any VAT is imposed upon or against either of the Asset Sellers in relation to the sale and transfer of the Acquired Assets as contemplated by this Agreement whereby the Asset Sellers are required to issue invoices to the buyers of the Acquired Assets inclusive of VAT in accordance with the requirements of applicable law, the Asset Sellers shall promptly notify Buyer, the German Transferee and the Netherlands Transferee, as applicable, of the amount of such VAT and shall issue a VAT invoice in accordance with the requirements of applicable law. Buyer shall remit, or shall cause the German Transferee and the Netherlands Transferee, as applicable, to remit, to the Asset Sellers, the VAT amounts specified in such VAT invoice plus fifty percent (50%) of any interest or surcharges assessed thereon by the tax authorities against either of the Asset Sellers (“ VAT Amount ”). The VAT Amount shall become due and payable at the latest within ten (10) Business Days following receipt of such VAT invoice and a copy of the VAT assessment notice stipulating any interest or surcharges by Buyer, the German Transferee and the Netherlands Transferee, as applicable. The Asset Sellers shall in such case, upon receipt of prior written consent from Buyer (which consent shall not be unreasonably withheld, conditioned or delayed), be entitled to exercise a VAT option with respect to their sales of the Acquired Assets. The payment claim of the Asset Sellers against Buyer, the German Transferee and the Netherlands Transferee, as applicable, shall not become time-barred until six (6) months after the time at which the assessment of VAT on the sale of the Acquired Assets becomes final and unappealable ( formell und materiell bestandskräftig ).

(e) In the event that any VAT is imposed upon or against Buyer, the German Transferee or the Netherlands Transferee, as applicable, in relation to the sale of the Acquired Assets as contemplated by this Agreement due to a reverse charge scenario, Buyer, the German Transferee and the Netherlands Transferee, as applicable, shall promptly notify PKI or the Asset Sellers of the amount of such VAT and attach a copy of the VAT assessment notice. The respective Asset Seller shall within ten (10) Business Days after receipt of the notice issue an invoice in accordance with the requirements of applicable law, as required, exclusive of VAT.

(f) The Parties will cooperate with each other in the provision of any information or preparation of any documentation that may be necessary or useful for obtaining any available mitigation, reduction or exemption of VAT or for seeking a refund or credit of VAT.

EXHIBIT E – TRANSITION SERVICES AGREEMENT

This TRANSITION SERVICES AGREEMENT (the “ Agreement ”) is made this [●] day of [●], 2016, by and between PerkinElmer, Inc., a Massachusetts corporation (“PKI”), and [                      ], a Delaware corporation (“ Buyer ”). PKI and Buyer are collectively referred to herein as the “Parties,” and each individually as a “Party.”

WHEREAS, Buyer and PKI are parties to a Master Purchase and Sale Agreement dated as of December 21, 2016 (the “ Acquisition Agreement ”);

WHEREAS, in order to enable Buyer to operate the Business in an effective manner, PKI has agreed to provide to Buyer certain services for the periods and on the terms and conditions set forth herein; and

WHEREAS, in order to enable PKI to operate certain portions of its business not sold to Buyer pursuant to the Acquisition Agreement in an effective manner, Buyer has agreed to provide to PKI certain services for the periods and on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual agreements and covenants set forth herein and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, and intending to be legally bound hereby, the Parties agree:

1.1 General . During the term of this Agreement each Party (or an Affiliate of each such Party designated by such Party for this purpose) shall provide, or cause such designated Affiliate to provide, the services (individually, a “ Service ” and collectively, the “ Services ”) as applicable to such Party as set forth in Schedules A and B attached hereto for up to the periods set forth on Schedules A and B , as applicable. PKI will consider all requests to provide additional services that are not included in the Services as of the date hereof in good faith. Any such additional service that PKI has agreed to provide (each such service an “ Additional Service ”) will be considered to be part of the Services. Fees for such Additional Services will be as agreed to between the Parties.

1.2 Cooperation . Each Party shall cause its employees to reasonably cooperate with employees of the other to the extent required for effective and timely delivery of the Services. In addition, each Party shall name a point of contact who shall be responsible for the day to day implementation of this Agreement, including attempted resolution of any issues that may arise during the performance of any of the Parties’ obligations hereunder.

1.3 Third Party Services . Each Party shall have the right to engage the services of independent contractors to deliver or assist in the delivery of the Services contemplated under this Agreement to the extent such Party uses such contractors for itself for similar Services. Each Party will impose on such third parties the confidentiality obligations specified in this Agreement and will use commercially reasonable efforts to supervise the performance of such third parties to ensure that the Services meet, in all material respects, the requirements of this Agreement.

E-1

1.4 Resources . PKI acknowledges that, as of Closing, it has suitable employees on-site or otherwise available to perform the Services to be performed by it hereunder. The Parties agree that in no event shall either Party be required to hire employees or engage consultants or contractors for the sole purpose of performing Services hereunder.

1.5 Standard of Performance . Each Party shall provide all Services with at least the same degree of care, skill and diligence with which PKI historically has provided such services for the benefit of the Business or PKI, as applicable.

1.6 Software . To the extent any Services involve access to database or other software systems (including without limitation any SAP applications), the Service Provider (as defined below) shall have no liability for any data entry errors, database errors, software bugs or errors, data stored or accessed by such systems or otherwise in any way relating to the Service Recipient’s (as defined below) use of such software applications or systems.

1.7 Conflict for Services . Notwithstanding anything to the contrary in this Agreement, including Schedules A or B , neither Party shall be required to provide any Services hereunder that may result in the breach or violation of any applicable law or any arrangement or agreement with any third party, including software licenses and support or maintenance agreements. Each Party represents to the other that, to its knowledge, it has all rights necessary to provide the Services to be provided by it hereunder.

1.8 Relationship with Sellers . Buyer agrees that from and after the Closing Buyer shall not hold itself out as having any affiliations with any Seller, including, and without limiting the foregoing, in connection with Buyer’s dealings with vendors. Buyer shall have no right to participate in or suggest the applicability of any volume discounts that PKI may have with any service provider or other third party.

2.1 Services Pricing . Schedules A and B each indicate, with respect to each Service, whether the costs to be charged for such Service are determined by (i) the pass-through billing method (“ Pass-Through Billing ”), (ii) the cost-plus-fixed-fee billing method (“ Cost-Plus Billing ”); or (iii) the fixed-cost billing method (“ Fixed-Cost Billing ”). The Pass-Through Billing, Cost-Plus Billing and Fixed-Cost methods applicable to Services are collectively referred to herein as the “ Service Cost .”

(a) Pass-Through Billing . The costs of Services determined by the Pass-Through Billing method shall be equal to the third-party costs and expenses actually incurred by the Party providing the Services (the “ Service Provider ”) on behalf of the Party receiving the Services (the “ Service Recipient ”) in providing such Service. If the Service Provider incurs costs or expenses on behalf of the Service Recipient as well as other businesses operated by the Service Provider in connection with the provision of such Services, the Service Provider will allocate any such costs or expenses on a pro rata basis based on the Service Recipient’s proportional share of its use of such Services, as determined in good faith by the Service Provider. Each Party or its agents shall keep and maintain such books and records as may be reasonably necessary to make such allocations. Each Party shall make copies of such books and records available to the other Party for inspection upon request and with reasonable notice.

E-2

(b) Cost-Plus Billing . The costs of Services determined by the Cost-Plus Billing method shall be equal to the costs and expenses actually incurred by the Service Provider on behalf of the Service Recipient in providing such Services, plus the costs set forth on Schedules A or B , as applicable.

(c) Fixed-Cost Billing . The costs of Services determined by the Fixed-Cost Billing method shall be equal to the costs set forth on Schedules A or B , as applicable.

For the avoidance of doubt, no Services shall be charged at a rate below the Service Provider’s actual cost. Additionally, certain Service Costs also contain administrative fees as noted on Schedule A . All actual amounts to be invoiced shall be calculated pursuant to the method listed on Schedules A or B , as applicable.

2.2 Invoicing and Payment . Within twenty (20) days following the end of each calendar month during the term hereof, each Party shall provide to the other Party a single invoice (an “ Invoice ”) totaling the Service Cost during such month. Such Invoice shall contain a brief description of each Service and the Service Cost, including a listing of all direct costs giving rise to the Service Cost and the third party charges included therein. The Party receiving the Invoice shall pay all undisputed amounts due under each Invoice no later than ten (10) days following receipt of an Invoice by wire transfer of immediately available funds to an account designated by the Party submitting the Invoice. A Party’s failure to pay any undisputed amounts in an Invoice within such 10-day period shall be considered a material breach of this Agreement pursuant to Section 6.2(a) . Every Invoice that is not paid when due shall bear interest on all undisputed amounts from and after the date on which such Invoice first became overdue at an annual rate equal to twelve percent (12%). Each Party agrees to pay on demand all costs of collection, including reasonable attorneys’ fees, incurred by the applicable Service Provider in collecting any such Invoice.

2.3 Taxes . The fees payable pursuant to this Section 2 shall be exclusive of any federal, state, municipal, or other U.S. or foreign government taxes, duties, excises, tariffs, fees, assessments or levies now or hereinafter imposed on the performance or delivery of Services or direct costs. Any taxes, duties, excises, tariffs, fees, assessments or levies imposed on the performance or delivery of Services or direct costs hereunder shall be the responsibility of the Service Recipient.

2.4 Records . Each Party shall keep such full and adequate records as are necessary to determine the charges to be assessed pursuant to this Section 2 , and shall have reasonable access to such records of the other.

3.1 Information Exchanges . Subject to applicable law and good faith claims of privilege, each Party shall provide the other Party with all information regarding itself and the transactions under this Agreement that the other Party reasonably believes are required to

E-3

comply with all applicable laws, ordinances, regulations and codes in connection with the provision of Services pursuant to this Agreement. This Agreement does not provide rights to either Party to access, store or use information of the other Party or its Affiliates that is not or was not related to the other Party’s business. Each Party agrees to use its reasonable best efforts not to access such information. Upon request of either Party, the other Party shall promptly return and/or destroy any copies of any reports, data, or other information relating to the requesting Party.

3.2 Confidential Information . Each Party shall hold in trust and maintain, and shall use commercially reasonable efforts to cause its Affiliates, consultants and advisors to hold in trust and maintain in strict confidence all Confidential Information relating to the other Party. “ Confidential Information ” shall mean all information disclosed by either Party to the other in connection with this Agreement, and includes, but is not limited to, economic, scientific, technical, product and business data, business plans, and the like, but shall not include (i) information which becomes generally available to the public other than by disclosure in violation of the provisions of this Section 3.2 , (ii) information which becomes available on a non-confidential basis to a Party from a source other than the other Party provided the Party is not, to the receiving Party’s knowledge, bound by a confidentiality agreement with or other contractual, legal or fiduciary obligation of confidentiality to the Disclosing Party or any other Party with respect to such information, (iii) information acquired or developed independently by a Party without violating this Section 3.2 or any other confidentiality agreement with the other Party, and (iv) information that either Party reasonably believes it is required to disclose by law, provided that it first notifies the other Party of such requirement and allows such Party a reasonable opportunity to seek a protective order or other appropriate remedy to prevent such disclosure. Without prejudice to the rights and remedies of either Party, a Party disclosing any Confidential Information to the other Party in accordance with the provisions of this Agreement shall be entitled to equitable relief by way of an injunction if the other Party hereto breaches or threatens to breach any provision of this Section 3.2 .

3.3 Security . Buyer hereby acknowledges that PKI retains the right to protect the confidentiality and security of its network and data, including as may be shared by Buyer, on and after the Closing. PKI may in its sole discretion update its hardware, software or administrative tools, including those that may relate to the Business.

4.1 Indemnification by PKI .

(a) Indemnification . PKI shall indemnify and hold Buyer and its Affiliates harmless against any damages, costs and expenses (including reasonable attorneys’ fees) arising from (i) the gross negligence or intentional misconduct of PKI or its designated Affiliates or permitted contractors in connection with the provision, receipt or use of any Services, or any other actions or inactions of PKI in connection therewith, or (ii) the material breach by PKI of any of its obligations hereunder.

PKI shall have sole control of the defense of any such action and all negotiations for its settlement or compromise, provided such settlement or compromise includes an unconditional release of Buyer and its Affiliates from all liability with respect to such claim in form and substance reasonably satisfactory to Buyer. Buyer shall reasonably cooperate with PKI in the defense of such claim, and may be represented, at Buyer’s expense, by counsel of Buyer’s selection.

4.2 Indemnification by Buyer .

(a) Indemnification . Buyer shall indemnify and hold PKI and its Affiliates harmless against any damages, costs and expenses (including reasonable attorneys’ fees) arising from (i) the gross negligence or intentional misconduct of Buyer in connection with the provision, receipt or use of any Services, or any other actions or inactions of Buyer in connection therewith, or (ii) the material breach by Buyer of any of its obligations hereunder.

5.2 Intellectual Property License .
