or could reasonably be expected to be materially adverse (i) to the business, financial condition or results of operations of the Acquired Business and its subsidiaries, taken as a whole, or (ii) to the ability of the Acquired Business to
timely, perform any of its obligations under the Acquisition Agreement, other than in the case of clause (i) or (ii) above, any event, state of facts, circumstance, development, change, effect or occurrence resulting from (A) changes
in general economic, regulatory or political conditions or in the securities, credit or financial markets in general, (B) general changes or developments in the business in which the Acquired Business and its subsidiaries operate, including any
changes in applicable law affecting such business, including generally applicable rules, regulations and administrative policies of the United States Food and Drug Administration (the “FDA”), or published interpretations thereof,
(C) the negotiation, execution, announcement, existence or performance of the Acquisition Agreement or the transactions contemplated thereby, including (x) any fees or expenses incurred in connection therewith, and (y) the impact of
the foregoing on relationships with customers, suppliers, employees, and regulators, (D) the identity of the Company or any of its affiliates as the acquiror of the Acquired Business, (E) compliance with the terms of, or the taking of any
action expressly required to be taken by the Acquired Business pursuant to the Acquisition Agreement or any other action consented to by the Company and the Arranger after the date hereof, (F) any acts of terrorism or war or any natural
disaster or weather-related event, (G) changes in generally accepted accounting principles or the interpretation thereof, (H) changes in the price or trading volume of the common stock of the Acquired Business (provided that this clause
(H) shall not be construed as providing that the change, event, circumstance, development, occurrence or state of facts giving rise to such change in price or trading volume does not constitute or contribute to an Acquired Business Material
Adverse Effect), (I) any failure to meet internal or published projections, forecasts or revenue or earning predictions or any downward revisions for any period (provided that this clause (I) shall not be construed as providing that the
change, event, circumstance, development, occurrence or state of facts giving rise to such failure does not constitute or contribute to an Acquired Business Material Adverse Effect), (J) any action, suit, investigation or proceeding made,
brought or threatened by any holder of Company Securities (as defined in the Acquisition Agreement in effect on the date hereof and without giving effect to any amendments thereunder), on the holder’s own behalf or on behalf of the Acquired
Business on a derivative basis (other than any actions, suits, investigations or proceedings made, brought or threatened by any of the Acquired Business’s officers or directors), arising out of or related to any of the transactions contemplated
hereby, including the Acquisition, or (K) any determination by, or the delay of a determination by, the FDA or any panel or advisory body empowered or appointed thereby, after the date of this Commitment Letter, with respect to the approval or
non-approval of new Medical Products (as defined in the Acquisition Agreement in effect on the date hereof and without giving effect to any amendments thereunder) or new uses of existing Medical Products, in each case of the Acquired Business or its
subsidiaries, as of the date of this Commitment Letter, except, in the case of the foregoing clause (A), (B) or (F), to the extent such changes or developments referred to therein could reasonably be expected to have a materially
disproportionate negative impact on the Acquired Business and its subsidiaries, taken as a whole, compared to other comparable participants in the Acquired Business’s industries). 
 Notwithstanding anything in this Commitment Letter to the contrary, (a) the only representations relating to the Company or the Acquired Business the accuracy of which will be a condition to the
availability of the Facilities on the Closing Date will be (i) such of the representations made by or with respect to the Acquired Business in the Acquisition Agreement as are material to the interests of the Lenders and Goldman Sachs (but only
to the extent that the Company or its affiliates have the right not to consummate the Acquisition, or to terminate their obligations (or otherwise do not have an obligation to close), under the Acquisition Agreement as a result of a failure of such
representations in the Acquisition Agreement to be true and correct) and (ii) the Specified Representations (as defined below), and (b) the terms of the documentation for the Facilities will be such that they do not impair the availability
of the Facilities on 

  
 3 

 
the Closing Date if the conditions set forth herein and in Annex D hereto are satisfied (it being understood that (I) to the extent any security interest in the intended collateral (other
than any collateral the security interest in which may be perfected by the filing of a UCC financing statement, domestic intellectual property filings or the delivery of stock certificates with respect to the Company, the Acquired Business and its
and their respective domestic subsidiaries) is not perfected on the Closing Date after your use of commercially reasonable efforts to do so, the perfection of such security interest(s) will not constitute a condition precedent to the availability of
the Facilities on the Closing Date but such security interest(s) will be required to be perfected after the Closing Date pursuant to arrangements to be mutually agreed by Goldman Sachs and the Company and (II) nothing in the preceding clause
(a) will be construed to limit the applicability of the individual conditions set forth herein or in Annex D). As used herein, “Specified Representations” means representations relating to incorporation or formation;
organizational power and authority to enter into the documentation relating to the Facilities; due execution, delivery and enforceability of such documentation; solvency; no conflicts with applicable laws in any material respect or charter
documents, in each case as they relate to entering into and performance under the Facilities; Federal Reserve margin regulations; the Investment Company Act; Patriot Act; FCPA; laws applicable to sanctioned persons; use of proceeds; historical
financial information (solely with respect to the Company), and, subject to the limitations on perfection of security interests set forth in the preceding sentence, the creation, perfection and priority of the security interests granted in the
proposed collateral. 
  

	3.	Syndication. 

 Goldman Sachs
intends and reserves the right to syndicate the Facilities to the Lenders (as defined in Annex B and Annex C), and you acknowledge and agree that the commencement of syndication shall occur in the discretion of Goldman Sachs. Goldman Sachs
will select the Lenders after consultation with the Company. Goldman Sachs will lead the syndication, including, subject to Section 1. above, determining the timing of all offers to potential Lenders, any title of agent or similar designations
or roles awarded to any Lender and the acceptance of commitments, the amounts offered and the compensation provided to each Lender from the amounts to be paid to Goldman Sachs pursuant to the terms of this Commitment Letter and the Fee Letter.
Goldman Sachs will determine the final commitment allocations and will notify the Company of such determinations. The Company agrees to use commercially reasonable efforts to ensure that Goldman Sachs’ syndication efforts benefit from the
existing lending relationships of the Company and the Acquired Business and their respective subsidiaries. To facilitate an orderly and successful syndication of the Facilities, you agree that, until the earlier of the termination of the syndication
as determined by Goldman Sachs and 90 days following the date of initial funding under the Facilities, the Company will not, and the Company will use commercially reasonable efforts to obtain contractual undertakings from the Acquired Business
that it will not, syndicate or issue, attempt to syndicate or issue, announce or authorize the announcement of the syndication or issuance of, or engage in discussions concerning the syndication or issuance of, any debt facility or any debt of the
Acquired Business or the Company or any of their respective subsidiaries or affiliates (other than the Facilities, the Notes (or other Permanent Debt (as defined in the Fee Letter)) and other indebtedness contemplated hereby to remain outstanding
after the Closing Date), including any renewals or refinancings of any existing debt facility or debt security, without the prior written consent of Goldman Sachs. 
 The Company agrees to cooperate with Goldman Sachs and agrees to use commercially reasonable efforts to cause the Acquired Business to cooperate with Goldman Sachs, in connection with (i) the
preparation of one or more information packages for each of the Facilities regarding the business, operations, financial projections and prospects of the Company and the Acquired Business (collectively, the “Confidential Information
Memorandum”) including, without limitation, all information relating to the transactions contemplated hereunder prepared by or on behalf of the Company or the Acquired Business deemed reasonably necessary by Goldman Sachs to complete the
syndication of the Facilities including, without limitation, obtaining (a) a public corporate family rating from Moody’s Investor 

  
 4 

 
Services, Inc. (“Moody’s”), (b) a public corporate credit rating from Standard & Poor’s Ratings Group, a division of The McGraw Hill Corporation
(“S&P”)) and (c) a public credit rating for each of the Facilities and the Notes from each of Moody’s and S&P prior to the launch of general syndication, and (ii) the presentation of one or more information
packages for each of the Facilities acceptable in format and content to Goldman Sachs (collectively, the “Lender Presentation”) in meetings and other communications with prospective Lenders or agents in connection with the
syndication of the Facilities (including, without limitation, direct contact between senior management and representatives, with appropriate seniority and expertise, of the Company and the Acquired Business with prospective Lenders and participation
of such persons in meetings); provided however that it is understood and agreed that, without limitation of any of the conditions set forth in Annex D hereto, the Company shall not be required to disclose communications relating to any
litigation or investigation, or the conduct thereof, solely to the extent that such disclosure would reasonably be expected to result in the waiver of the attorney-client privilege or work product protection applicable thereto. Notwithstanding
anything to the contrary contained in the Commitment Letter or the Fee Letter or any other letter agreement or undertaking concerning the transactions contemplated hereunder to the contrary (but without limiting your obligations to assist in
syndication as described above or any condition precedent expressly set forth in Section 2 above or Annex D hereto), neither of (x) obtaining the ratings referenced above or (y) the achievement of a successful syndication of the
Facilities (as determined by Goldman Sachs), shall constitute a condition precedent to the commitments hereunder or the funding of any of the Facilities on the Closing Date. The Company will be solely responsible for the contents of any such
Confidential Information Memorandum and Lender Presentation and all other information, documentation or materials delivered to Goldman Sachs in connection therewith, including with respect to the business of the Company and the Acquired Business and
the transactions contemplated hereunder (collectively, the “Information”) and acknowledges that Goldman Sachs will be using and relying upon the Information without independent verification thereof (it being understood and agreed
that the Company may cause the Acquired Business to deliver to Goldman Sachs an authorization letter containing a customary “10b-5” representation with respect to the Information of the Acquired Business contained in such Confidential
Information Memorandum or Lender Presentation). The Company agrees that Information regarding the Facilities and Information provided by the Company, the Acquired Business or their respective representatives to Goldman Sachs in connection with the
Facilities (including, without limitation, draft and execution versions of the Loan Documents, the Confidential Information Memorandum, the Lender Presentation, publicly filed financial statements, and draft or final offering materials relating to
contemporaneous or prior securities issuances by the Company or the Acquired Business) may be disseminated to potential Lenders and other persons through one or more secure internet sites (including an IntraLinks, SyndTrak or other secure
electronic workspace (the “Platform”)) created for purposes of syndicating the Facilities or otherwise, in accordance with Goldman Sachs’ standard syndication practices, and you acknowledge that neither Goldman Sachs nor any of
its affiliates will be responsible or liable to you or any other person or entity for damages arising from the use by others of any Information or other materials obtained on the Platform. 
 The Company acknowledges that certain of the Lenders may be “public side” Lenders (i.e. Lenders that do not wish to receive material non-public information with respect to the
Company, the Acquired Business or their respective affiliates or any of their respective securities) (each, a “Public Lender”). At the request of Goldman Sachs, the Company agrees to prepare an additional version of the Confidential
Information Memorandum and the Lender Presentation to be used by Public Lenders that does not contain material non-public information concerning the Company, the Acquired Business, or their respective affiliates or securities. The information to be
included in the additional version of the Confidential Information Memorandum will be substantially consistent with the information included in any offering memorandum for the offering for the Notes. It is understood that in connection with your
assistance described above, you will provide, and cause all other applicable persons (which may include the Acquired Business) to provide, authorization letters to Goldman Sachs authorizing the distribution of the

  
 5 

 
Information to prospective Lenders and containing a customary “10b-5” representation to Goldman Sachs (and, in the case of the public-side version, a representation that such
Information does not include material non-public information about the Company, the Acquired Business, or their respective affiliates or their respective securities). In addition, the Company will clearly designate as such all Information provided
to Goldman Sachs by or on behalf of the Company or the Acquired Business which is suitable to make available to Public Lenders. The Company acknowledges and agrees that the following documents may be distributed to all Lenders (including Public
Lenders) (unless the Company, after having been given a reasonable opportunity to review such documents, promptly notifies Goldman Sachs in writing prior to such distribution that any such document contains material non-public information with
respect to the Company, the Acquired Business or their respective affiliates or securities): (a) drafts and final versions of the Loan Documents; (b) administrative materials prepared by Goldman Sachs for prospective Lenders (such as a
lender meeting invitation, allocations and funding and closing memoranda); and (c) term sheets and notification of changes in the terms of the Facilities. 
  

	4.	Information. 

 The Company
represents and covenants that (which representation and warranty with respect to the Information relating to the Acquired Business is made to the best of your knowledge) (i) all Information (other than financial projections, forecasts and other
forward looking statements (collectively, the “Projections”)) provided directly or indirectly by the Acquired Business or the Company to Goldman Sachs or the Lenders in connection with the transactions contemplated hereunder is and
will be, when taken as a whole, complete and correct in all material respects and does not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not
misleading and (ii) the Projections that have been or will be made available to Goldman Sachs or the Lenders by or on behalf of the Acquired Business or the Company have been and will be prepared in good faith based upon assumptions that are
believed by the preparer thereof to be reasonable at the time such Projections are furnished to Goldman Sachs or the Lenders, it being understood and agreed that Projections are not a guarantee of financial performance and actual results may differ
from Projections and such differences may be material. You agree that if at any time prior to the later of (i) the Closing Date and (ii) the termination of the syndication of the Facilities as determined by Goldman Sachs, but in no event
exceeding 90 days after the Closing Date, any of the representations in the preceding sentence would be incorrect in any material respect if the Information and Projections were being furnished, and such representations were being made, at such
time, then you will promptly supplement, or cause to be supplemented, the Information and Projections so that such representations will be correct in all material respects under those circumstances. In arranging and syndicating the Facilities, we
will be entitled to use and rely on the Information and the Projections without responsibility for independent verification thereof. We will have no obligation to conduct any independent evaluation or appraisal of the assets or liabilities of you,
the Borrower, the Acquired Business or any other party or to advise or opine on any related solvency issues. 
  

	5.	Indemnification and Related Matters. 

 In connection with arrangements such as this, it is our firm’s policy to receive indemnification. The Company agrees to the provisions with respect to our indemnity and other matters set forth in
Annex A, which is incorporated by reference into this Commitment Letter. 
  

	6.	Assignments. 

 This Commitment
Letter may not be assigned by you without the prior written consent of Goldman Sachs (and any purported assignment without such consent will be null and void), is intended to be solely for the benefit of Goldman Sachs and the other parties hereto
and, except as set forth in Annex A hereto, is not 

  
 6 

 
intended to confer any benefits upon, or create any rights in favor of, any person other than the parties hereto. Goldman Sachs may assign its commitments and agreements hereunder, in whole or in
part, to any of its affiliates and, as provided above, to any Lender prior to the Closing Date. In addition, until the termination of the syndication of the Facilities, as determined by Goldman Sachs, Goldman Sachs may, in consultation with the
Company, assign its commitments and agreements hereunder, in whole or in part, to additional arrangers or other Lenders. Any assignment by Goldman Sachs to any potential Lender made in accordance with this Section 6 and/or any other provisions
set forth in this Commitment Letter, in each case, prior to the Closing Date, will only relieve Goldman Sachs of its obligations set forth herein to fund that portion of the commitments so assigned if such assignment was to an Additional Agent.
Neither this Commitment Letter nor the Fee Letter may be amended or any term or provision hereof or thereof waived or otherwise modified except by an instrument in writing signed by each of the parties hereto or thereto, as applicable, and any term
or provision hereof or thereof may be amended or waived only by a written agreement executed and delivered by all parties hereto or thereto. 
  

	7.	Confidentiality. 

 Please note that
this Commitment Letter, the Fee Letter and any written communications provided by, or oral discussions with, Goldman Sachs in connection with this arrangement are exclusively for the information of the Company and may not be disclosed by you to any
third party or circulated or referred to publicly without our prior written consent except, after providing written notice to Goldman Sachs, pursuant to a subpoena or order issued by a court of competent jurisdiction or by a judicial, administrative
or legislative body or committee; provided that we hereby consent to your disclosure of (i) this Commitment Letter, the Fee Letter and such communications and discussions, to the Company’s subsidiaries and to Company’s
and the Company’s subsidiaries’ respective officers, directors, agents and advisors (including all legal counsel, independent auditors and other experts or agents) who are directly involved in the consideration of the Facilities
(including, providing accounting and tax advice to Company and/or its subsidiaries with respect thereto) and who have been informed by you of the confidential nature of such advice and this Commitment Letter and the Fee Letter and who have agreed to
treat such information confidentially, (ii) this Commitment Letter or the information contained herein and the Fee Letter to the Acquired Business and its affiliates to the extent you notify such persons of their obligations to keep such
material confidential, and to the Acquired Business’s and its affiliates’ respective officers, directors, agents and advisors who are directly involved in the consideration of the Facilities to the extent such persons agree to hold the
same in confidence (provided that any disclosure of the Fee Letter or its terms or substance to the Acquired Business or its officers, directors, agents and advisors shall be redacted in a manner satisfactory to Goldman Sachs and the
Company), (iii) this Commitment Letter and the Fee Letter as required by applicable law or compulsory legal process (including (x) the filing of the Commitment Letter in public securities filings and (y) to the extent required by
applicable law to be so disclosed, the aggregate amount of the fees payable pursuant to the terms of the Fee Letter, presented as an aggregate amount of all fees payable by the Company in connection with the Acquisition and the other transactions
contemplated by this Commitment Letter, but not the Fee Letter itself or any other information contained therein (the “Public Securities Filing”)) (in which case, you agree (other than in the case of the Public Securities Filing) to
inform us promptly thereof), (iv) the information contained in Annex B and Annex C, in any prospectus or other offering memorandum relating to the Notes, (v) the existence of this Commitment Letter and information about the Facilities to
market data collectors, similar services providers to the lending industry, and service providers to Goldman Sachs and the Lenders in connection with the administration and management of the Facilities, (vi) upon the request or demand of any
regulatory authority purporting to have jurisdiction over such person or any of its affiliates (in which case, you agree to inform us promptly thereof) and (vii) the information contained in Annex B and Annex C to Moody’s and S&P;
provided that such information is supplied to Moody’s and S&P only on a confidential basis after consultation with Goldman Sachs. 

  
 7 

 Goldman Sachs agrees that it will treat as confidential all information provided to it hereunder by or on
behalf of you, the Acquired Business or any of your or their respective subsidiaries or affiliates, and shall not disclose such information to any third party or circulate or refer to publicly such information without the Company’s prior
written consent; provided, however, that nothing herein will prevent Goldman Sachs from disclosing any such information (a) pursuant to the order of any court or administrative agency or in any pending legal or administrative
proceeding, or otherwise as required by applicable law or compulsory legal process (in which case such person agrees to inform you promptly thereof to the extent not prohibited by law), (b) upon the request or demand of any regulatory authority
purporting to have jurisdiction over such person or any of its affiliates, (c) to the extent that such information is publicly available or becomes publicly available other than by reason of improper disclosure by such person, (d) to such
person’s affiliates and their respective officers, directors, partners, members, employees, legal counsel, independent auditors and other experts or agents who need to know such information and on a confidential basis, (e) to potential and
prospective Lenders, participants and any direct or indirect contractual counterparties to any swap or derivative transaction relating to the borrower or its obligations under the Facilities, in each case, who have agreed to keep such information
confidential on terms not less favorable than the provisions hereof in accordance with the standard syndication processes of Goldman Sachs or customary market standards for the dissemination of such type of information, (f) to Moody’s and
S&P and other rating agencies or to market data collectors as determined by Goldman Sachs; provided that such information is limited to Annex B and Annex C and is supplied only on a confidential basis, (g) received by such
person on a non-confidential basis from a source (other than you, the Acquired Business or any of your or their affiliates, advisors, members, directors, employees, agents or other representatives) not known by such person to be prohibited from
disclosing such information to such person by a legal, contractual or fiduciary obligation, (h) to the extent that such information was already in Goldman Sachs’ possession or is independently developed by Goldman Sachs or (i) for
purposes of establishing a “due diligence” defense. Goldman Sachs’ obligation under this provision shall remain in effect until the earlier of (i) one year from the date hereof and (ii) the date the definitive Loan Documents
are entered into by Goldman Sachs, at which time any confidentiality undertaking in the definitive Loan Documents shall supersede this provision. 
  

	8.	Absence of Fiduciary Relationship; Affiliates; Etc. 

 As you know, Goldman Sachs (together with its affiliates, “GS”) is a full service financial institution engaged, either directly or through its affiliates, in a broad array of activities,
including commercial and investment banking, financial advisory, market making and trading, investment management (both public and private investing), investment research, principal investment, financial planning, benefits counseling, risk
management, hedging, financing, brokerage and other financial and non-financial activities and services globally. In the ordinary course of their various business activities, GS and funds or other entities in which GS invests or with which they
co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the
accounts of their customers. In addition, GS may at any time communicate independent recommendations and/or publish or express independent research views in respect of such assets, securities or instruments. Any of the aforementioned activities may
involve or relate to assets, securities and/or instruments of the Company, the Acquired Business and/or other entities and persons which may (i) be involved in transactions arising from or relating to the arrangement contemplated by this
Commitment Letter or (ii) have other relationships with the Company or its affiliates. In addition, GS may provide investment banking, commercial banking, underwriting and financial advisory services to such other entities and persons. The
arrangement contemplated by this Commitment Letter may have a direct or indirect impact on the investments, securities or instruments referred to in this paragraph, and employees working on the financing contemplated hereby may have been involved in
originating certain of such investments and those employees may receive credit internally therefor. Although GS in the course of such other activities and 

  
 8 

 
relationships may acquire information about the transaction contemplated by this Commitment Letter or other entities and persons which may be the subject of the financing contemplated by this
Commitment Letter, GS shall have no obligation to disclose such information, or the fact that GS is in possession of such information, to the Company or to use such information on the Company’s behalf. 

Consistent with GS’s policies to hold in confidence the affairs of its customers, GS will not furnish confidential information obtained from you by
virtue of the transactions contemplated by this Commitment Letter to any of its other customers. Furthermore, you acknowledge that neither GS nor any of its affiliates has an obligation to use in connection with the transactions contemplated by this
Commitment Letter, or to furnish to you, confidential information obtained or that may be obtained by them from any other person. 
 GS may have
economic interests that conflict with those of the Company, its equity holders and/or its affiliates. You agree that GS will act under this Commitment Letter as an independent contractor and that nothing in this Commitment Letter or the Fee Letter
or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between GS and the Company, its equity holders or its affiliates. You acknowledge and agree that the transactions contemplated by
this Commitment Letter and the Fee Letter (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between GS, on the one hand, and the Company, on the other, and in connection therewith
and with the process leading thereto, (i) GS has not assumed (A) an advisory responsibility in favor of the Company, its equity holders or its affiliates with respect to the financing transactions contemplated hereby or (B) a
fiduciary responsibility in favor of the Company, its equity holders or its affiliates with respect to the transactions contemplated hereby, or in each case, the exercise of rights or remedies with respect thereto or the process leading thereto
(irrespective of whether GS has advised, is currently advising or will advise the Company, its equity holders or its affiliates on other matters) or any other obligation to the Company except the obligations expressly set forth in this Commitment
Letter and the Fee Letter and (ii) GS is acting solely as a principal and not as the agent or fiduciary of the Company, its management, equity holders, affiliates, creditors or any other person. the Company acknowledges and agrees that the
Company has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. The Company agrees
that it will not claim that GS has rendered advisory services of any nature or respect with respect to the financing transactions contemplated hereby, or owes a fiduciary or similar duty to the Company, in connection with such transactions or the
process leading thereto. As each of the parties hereto is aware, Goldman, Sachs & Co. has been retained by the Company (or one of its affiliates) as financial advisor (in such capacity, the “Financial Advisor”) in
connection with the Acquisition. Each of the parties hereto agrees to such retention, and further agrees not to assert any claim it might allege based on any actual or potential conflicts of interest that might be asserted to arise or result from,
on the one hand, the engagement of the Financial Advisor or Goldman Sachs and/or its affiliates’ arranging or providing or contemplating arranging or providing financing for a competing bidder and, on the other hand, our and our
affiliates’ relationships with the Company or any of the other parties hereto as described and referred to herein. In addition, Goldman Sachs may employ the services of its affiliates in providing services and/or performing its or their
obligations hereunder and may exchange with such affiliates information concerning the Company, the Acquired Business and other companies that may be the subject of this arrangement, and such affiliates will be entitled to the benefits afforded to
Goldman Sachs hereunder. 
 In addition, please note that GS does not provide accounting, tax or legal advice. Notwithstanding anything herein
to the contrary, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Facilities and all materials of any kind

 ANNEX A 

In the event that Goldman Sachs becomes involved in any capacity in any action, proceeding or investigation brought by or against any
person, including shareholders, partners, members or other equity holders of the Company or the Acquired Business in connection with or as a result of either this arrangement or any matter referred to in this Commitment Letter or the Fee Letter
(together, the “Letters”), the Company agrees to periodically reimburse Goldman Sachs for its reasonable legal and other expenses (including the cost of any investigation and preparation) incurred in connection
therewith. The Company also agrees to indemnify and hold Goldman Sachs harmless against any and all losses, claims, damages or liabilities to any such person in connection with or as a result of either this arrangement or any matter referred to in
the Letters (whether or not such investigation, litigation, claim or proceeding is brought by you, your equity holders or creditors or an indemnified person and whether or not any such indemnified person is otherwise a party thereto), except to the
extent that such loss, claim, damage or liability has been found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of Goldman Sachs in performing the services
that are the subject of the Letters. If for any reason the foregoing indemnification is unavailable to Goldman Sachs or insufficient to hold it harmless, then the Company will contribute to the amount paid or payable by Goldman Sachs as a result of
such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative economic interests of (i) the Company and the Acquired Business and their respective affiliates, shareholders, partners, members or other equity
holders on the one hand and (ii) Goldman Sachs on the other hand in the matters contemplated by the Letters as well as the relative fault of (i) the Company and the Acquired Business and their respective affiliates, shareholders, partners,
members or other equity holders on the one hand and (ii) Goldman Sachs with respect to such loss, claim, damage or liability and any other relevant equitable considerations. The reimbursement, indemnity and contribution obligations of the
Company under this paragraph will be in addition to any liability which the Company may otherwise have, will extend upon the same terms and conditions to any affiliate of Goldman Sachs and the partners, members, directors, agents, employees and
controlling persons (if any), as the case may be, of Goldman Sachs and any such affiliate, and will be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, Goldman Sachs, any such
affiliate and any such person. The Company also agrees that neither any indemnified party nor any of such affiliates, partners, members, directors, agents, employees or controlling persons will have any liability to the Company or any person
asserting claims on behalf of or in right of the Company or any other person in connection with or as a result of either this arrangement or any matter referred to in the Letters, except in the case of the Company to the extent that any losses,
claims, damages, liabilities or expenses incurred by the Company or its affiliates, shareholders, partners or other equity holders have been found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the
gross negligence or willful misconduct of such indemnified party in performing the services that are the subject of the Letters; provided, however, that in no event will such indemnified party or such other parties have
any liability for any indirect, consequential, special or punitive damages in connection with or as a result of such indemnified party’s or such other parties’ activities related to the Letters. Promptly after receipt by Goldman Sachs of
notice of its involvement in any action, proceeding or investigation, Goldman Sachs shall, if a claim for indemnification in respect thereof is to be made against the Company under this Annex A, notify the Company of such involvement. Failure by
Goldman Sachs to so notify the Company shall not relieve the Company from the obligation to indemnify Goldman Sachs (or any other indemnified person) under this Annex A except to the extent that the Company suffers actual prejudice as a result of
such failure, and shall not relieve the Company, from its obligation to provide reimbursement and contribution to Goldman Sachs. If any person is entitled to indemnification under this Annex A (an “Indemnified Person”)
with respect to any action or proceeding brought by a third party that is also brought against the Company, the Company shall be entitled to assume the defense of any such action or proceeding with counsel reasonably satisfactory to the Indemnified
Person. Upon assumption by the Company of the defense of any such action or proceeding, 

  
 Annex A-1

 
the Indemnified Person shall have the right to participate in such action or proceeding and to retain its own counsel but the Company shall not be liable for any legal expenses of other
counsel subsequently incurred by such Indemnified Person in connection with the defense thereof unless (i) the Company has agreed to pay such fees and expenses, (ii) the Company shall have failed to employ counsel reasonably satisfactory
to the Indemnified Person in a timely manner or (iii) the Indemnified Person shall have been advised by counsel that there are actual or potential conflicting interests between the Company and the Indemnified Person, including situations in
which there are one or more legal defenses available to the Indemnified Person that are different from or additional to those available to the Company. The Company shall not consent to the terms of any compromise or settlement of any action defended
by the Company in accordance with the foregoing without the prior written consent of the Indemnified Person. The provisions of this Annex A will survive any termination or completion of the arrangement provided by the Letters.

  
 Annex A-2

	  	On or before the final maturity date of each of the Senior Facilities, the Borrower will have the right, but not the obligation, to increase the amount of the Senior Facilities
by incurring one or more incremental term loan facilities and/or increasing the Revolving Facility (each, an “Incremental Facility”) in an aggregate principal amount not to exceed the greater of (1) $500 million and (2) the
maximum amount at such time that could be incurred without causing the pro forma Net Senior Secured Leverage Ratio (to be defined in the Loan Documents, and to be net of up to $250 million of unrestricted cash and cash equivalents of the Borrower
and its subsidiaries) to exceed 3.50:1.00 (and, for purposes of the test in this clause (2) to include all such incremental loans and commitments, assuming they were fully drawn, and whether or not secured and whether secured on a first-lien or

yield applicable to a Non-Institutional Incremental Term Facility is more than 0.50% higher than the corresponding yield applicable to the Tranche A Term Facility, then the interest rate margins with respect to the Tranche A Term Facility will be
increased by an amount equal to the difference between the yield with respect to such Non-Institutional Incremental Term Facility and the corresponding interest rate on the Tranche A Term Facility, minus, 0.50% or (y) the yield applicable to an
Institutional Incremental Term Facility is more than 0.50% higher than the corresponding yield applicable to the Tranche B Term Facility, then the interest rate margins with respect to the Tranche B Term Facility will be increased by an amount equal
to the difference between the yield with respect to such Institutional Incremental Term Facility and the corresponding interest rate on the Tranche B Term Facility, minus, 0.50%, (b) the maturity date applicable to any such term Incremental Facility
will not be earlier than the latest maturity date of the existing Senior Facilities; provided that, notwithstanding the foregoing and subject to the other terms of this paragraph, the Borrower will have the right to incur term

Facility”) in an aggregate amount not to exceed $250 million, (c) the weighted average life to maturity of any term Incremental Facility (other than a Specified Incremental Term Facility) will not
be

  
 Annex B-2

			
		  	earlier than that of any existing Term Facility, (d) the weighted average life to maturity of any Specified Incremental Term Facility will not be earlier than that of the Tranche
A Term Facility and (e) all other terms of such term Incremental Facility, if not consistent with the terms of the existing Term Facilities, must be reasonably acceptable to the Administrative Agent and (iii) if all or a portion of such Incremental
Facility is a revolving Incremental Facility, such revolving facility will be documented solely as an increase to the commitments with respect to the Revolving Facility, without any change in terms. Such increased amounts will be provided by
existing Lenders or other persons who become Lenders in connection therewith; provided that no existing Lender will be obligated to provide any such increased portion of the Senior Facilities.
		
		  	“Institutional Incremental Term Facility” means a term Incremental Facility that is an Institutional Term Facility.
		
		  	“Institutional Term Facility” means a term loan facility of the type marketed primarily to institutional term loan lenders (as opposed to commercial banks) in
the primary syndication thereof (including, for the avoidance of doubt, the Tranche B Term Facility).

anniversary of the Closing Date. No amortization will be required with respect to the Revolving Facility.
		
	 Swing Line Loans:

		  	 (A)   Initially, with respect to loans made under the Tranche A Term Facility and the Revolving
Facility:

		
		  	 (i)       at the Base Rate plus the margin per annum set forth in the table below
opposite the applicable Rating Level (as defined below) as of the Closing Date; or

  
 Annex B-4

			
		
		  	 (ii)      at the reserve adjusted Eurodollar Rate plus the margin per annum set forth in
the table below opposite the applicable Rating Level as of the Closing Date;

  

											
	  	 	Rating Level	  	Base Rate
Margin	 	 	Eurodollar
Rate Margin	 
	 	 Level I
	  	 	1.75	% 	 	 	2.75	% 
	 	 Level II
	  	 	1.875	% 	 	 	2.875	% 
	 	 Level III
	  	 	2.00	% 	 	 	3.00	% 

  

			
		  	where: (x) “Level I” means the Company shall have obtained a public corporate family rating of Ba3 (with a stable or positive outlook) or better by Moody’s
and a public credit rating of BB- (with a stable or positive outlook) or better by S&P, (y) “Level II” means the Company shall have obtained (i) a public corporate family rating of B1 (with a stable or positive outlook) by
Moody’s and a public credit rating of BB- (with a stable or positive outlook) by S&P or (ii) a public corporate family rating of Ba3 (with a stable or positive outlook) by Moody’s and a public credit rating of B+ (with a stable or
positive outlook) by S&P and (z) “Level III” means the Company shall have obtained a public corporate family rating or public credit rating (or outlook) worse than Level II. Level I, Level II and Level III are sometimes referred
to herein as “Rating Levels”.
		
		  	 (B)   With respect to loans made under the Tranche B Term Facility:

		
		  	 (i)     at the Base Rate plus 2.50% per annum;
or
  
 (ii)    at
the reserve adjusted Eurodollar Rate plus 3.50% per annum.

		
		  	Beginning on the date on which the Borrower delivers to the Lenders the required financial statements for the second full fiscal quarter after the Closing Date, the applicable
margin for the Tranche A Term Facility and the Revolving Facility will be subject to step downs to be determined based on the ratio of consolidated indebtedness of the Borrower and its subsidiaries as of the date of such financial statements to
EBITDA of the Borrower and its subsidiaries for the twelve-month period ended on such date (the “Leverage Ratio”).
		
		  	As used herein, the terms “Base Rate” and “reserve adjusted Eurodollar Rate” will have meanings customary and appropriate for financings of this
type, and the basis for calculating accrued interest

  
 Annex B-5

			
		  	and the interest periods for loans bearing interest at the reserve adjusted Eurodollar Rate will be customary and appropriate for financings of this type subject to, with respect
to the Tranche B Term Facility, a reserve adjusted Eurodollar Rate “floor” of 1.00% and a Base Rate “floor” of 2.00%. In no event shall the Base Rate be less than the sum of (i) the one-month reserve adjusted Eurodollar Rate
(after giving effect to any reserve adjusted Eurodollar Rate “floor”) plus (ii) the difference between the applicable stated margin for reserve adjusted Eurodollar Rate loans and the applicable stated margin for Base Rate
loans.
		
		  	After the occurrence and during the continuance of an Event of Default, interest on overdue amounts will accrue at a rate equal to the rate then applicable thereto, or otherwise
at a rate equal to the rate then applicable to loans bearing interest at the rate determined by reference to the Base Rate, in each case plus an additional two percentage points (2.00%) per annum. Such interest will be payable on
demand.
		
	 Interest Payments:
	  	Quarterly for loans bearing interest with reference to the Base Rate; except as set forth below, on the last day of selected interest periods (which will be one, two, three and
six months) for loans bearing interest with reference to the reserve adjusted Eurodollar Rate (and at the end of every three months, in the case of interest periods of longer than three months); and upon prepayment (solely with respect to interest
accrued on such amounts prepaid), in each case payable in arrears and computed on the basis of a 360-day year (365/366-day year with respect to loans bearing interest with reference to the Base Rate).
		
	 Commitment Fees:
	  	Commitment fees equal to 0.50% per annum times the daily average undrawn portion of the Revolving Facility of each Lender (other than any Defaulting Lender) (reduced by
the amount of Letters of Credit issued and outstanding) will accrue from the Closing Date and will be payable quarterly in arrears; provided that such commitment fee shall be subject to a step down to 0.375% based upon compliance with
a leverage test to be determined.
		
	 Letters of Credit Fees:
	  	A fee equal to (i) the applicable margin then in effect for loans bearing interest at the reserve adjusted Eurodollar Rate made under the Revolving Facility, times
(ii) the average daily maximum aggregate amount available to be drawn under all Letters of Credit, will be payable quarterly in arrears to the Lenders under the Revolving Facility (other than any Defaulting Lender). In addition, a fronting fee,
to be agreed upon between the issuer of each Letter of Credit and the Borrower, will be payable to such issuer, as well as certain customary fees assessed thereby.
		
	 Voluntary Prepayments:
	  	The Senior Facilities may be prepaid in whole or in part, subject to the “Call Premium” below, without premium or penalty; provided that loans bearing
interest with reference to the reserve adjusted Eurodollar Rate will be prepayable only on the last day of the related interest

  
 Annex B-6

			
		  	period unless the Borrower pays any related breakage costs. Voluntary prepayments of the Term Facilities will be applied to the Term Facilities and scheduled amortization
payments as directed by the Borrower.
		
	 Mandatory Prepayments:
	  	The following mandatory prepayments will be required (subject to certain basket amounts to be negotiated in the definitive Loan Documents):
		
		  	 1.        Asset Sales: Prepayments in an amount equal to 100% of the net cash
proceeds of the sale or other disposition of any property or assets of the Borrower or its subsidiaries (subject to certain exceptions to be determined), other than net cash proceeds of sales or other dispositions of inventory in the ordinary course
of business and net cash proceeds (not in excess of an amount to be agreed upon in the aggregate) that are reinvested (or committed to be reinvested, to the extent actually reinvested within six months of such commitment) in other long-term assets
useful in the business of the Borrower and its subsidiaries within one year of receipt thereof.

		
		  	 2.        Insurance Proceeds: Prepayments in an amount equal to 100% of the net
cash proceeds of insurance paid on account of any loss of any property or assets of the Borrower or its subsidiaries, other than net cash proceeds (not in excess of an amount to be agreed upon in the aggregate) that are reinvested (or committed to
be reinvested, to the extent actually reinvested within six months of such commitment) in other long-term assets useful in the business of the Borrower and its subsidiaries (or used to replace damaged or destroyed assets) within one year of receipt
thereof.

		
		  	 3.        Equity Offerings: Prepayments in an amount equal to 50% (subject to
reductions to a lower percentage upon achievement of certain financial performance measures to be determined) of the net cash proceeds received from the issuance of equity securities of the Borrower or its subsidiaries (other than issuances pursuant
to employee stock plans); provided that no such prepayment of the Senior Facilities will be required to the extent such net cash proceeds are applied towards prepayment of the Bridge Loans or to the redemption of the Convertible
Notes.

		
		  	 4.        Incurrence of Indebtedness: Prepayments in an amount equal to 100% of
the net cash proceeds received from the incurrence of indebtedness by the Borrower or its subsidiaries (other than indebtedness otherwise permitted under the Loan Documents including, but not limited to, indebtedness raised to redeem the Convertible
Notes), payable no later than the first business day following the date of receipt.

  
 Annex B-7

			
		  	 5.        Excess Cash Flow: Prepayments in an amount equal to 50% (subject to
reductions to a lower percentage upon achievement of certain financial performance measures to be determined) of Excess Cash Flow payable within 90 days of each fiscal year-end, commencing with fiscal year-end 2013. Excess Cash Flow will be defined
in the applicable Loan Document and will include deductions for amounts applied during, or to be applied within a period following, the applicable fiscal year to redeem Convertible Notes, subject to terms and conditions to be
agreed.

		
		  	All mandatory prepayments will be made without penalty or premium (except for breakage costs, if any) and will be applied, first, pro rata to the Term Facilities (and,
with respect to each Term Facility, applied to remaining scheduled amortization payments of such Term Facility in the case of the first eight payments, in direct order of maturity and thereafter, on a pro rata basis); provided that, at
the election of holders of loans under the Tranche B Term Facility, the portion of proceeds otherwise allocable thereto may be allocated to repay the loans under Tranche A Term Facility in full prior to prepayment of the loans under the
Tranche B Term Facility held by such holders; and, second, to outstanding loans (without the permanent reduction of commitments) under the Revolving Facility.
		
	 Call Premium:
	  	In the event that all or any portion of the Tranche B Term Facility is (i) repaid, prepaid, refinanced or replaced or (ii) repriced or effectively refinanced through any waiver,
consent or amendment (in each case, in connection with any waiver, consent or amendment to the Tranche B Term Facility directed at, or the result of which would be, the lowering of the effective interest cost or the weighted average yield of the
Tranche B Term Facility or the incurrence of any debt financing having an effective interest cost or weighted average yield that is less than the effective interest cost or weighted average yield of the Tranche B Term Facility (or portion thereof)
so repaid, prepaid, refinanced, replaced or repriced (a “Repricing Transaction”)) occurring on or prior to the first anniversary of the Closing Date, such repayment, prepayment, refinancing, replacement or repricing will be made at
101.0% of the principal amount so repaid, prepaid, refinanced, replaced or repriced. If all or any portion of the Tranche B Term Facility held by any Lender is repaid, prepaid, refinanced or replaced pursuant to a “yank-a-bank” or similar
provision in the Loan Documents as a result of, or in connection with, such Lender not agreeing or otherwise consenting to any waiver, consent or amendment referred to in clause (ii) above (or otherwise in connection with a Repricing Transaction),
such repayment, prepayment, refinancing or replacement will be made at 101.0% of the principal amount so repaid, prepaid, refinanced or replaced.
		
	 Security:
	  	The Senior Facilities, each Guarantee, any interest rate and/or currency hedging obligations of the Borrower or any Guarantor owed to the Administrative Agent, the Arranger, any
Lender or any affiliate

the date hereof.
		
		  	In addition, the Loan Documents shall provide that loans under the Tranche B Term Facility (but not loans under the Revolving Facility) may be purchased by Borrower through
“Dutch” auctions in which all Lenders under the Tranche B Term Facility are invited to participate on a pro rata basis in accordance with customary procedures to be agreed, subject to customary terms and conditions including without
limitation: (a) any such loans acquired by Borrower shall be retired and cancelled promptly upon acquisition thereof, (b) Borrower must provide a customary representation and warranty to the effect that it is not in possession of any information

Senior Facilities (“Requisite Lenders”), provided that, in addition to the approval of Requisite Lenders, (x) any amendment that would disproportionately affect the obligation of the Borrower to make payment of
the loans under the Revolving Facility or the Term Facilities will not be effective without the approval of holders of more than 50% of such class of loans and (y) the consent of each Lender directly and adversely affected thereby will be required

“most favored nation” provision on terms to be mutually agreed by the Arranger and the Borrower and that each Lender under the tranche the maturity date of which is being extended shall have the opportunity to participate in such extension
on the same terms and conditions as each other Lender under such tranche.

  
 Annex B-12

			
		  	In addition, on or before the final maturity date of each of the Senior Facilities, the Borrower shall have the right to amend (or amend and restate) of the Loan Documents to (a)
add one or more additional or replacement credit facilities thereto and changes related thereto and (b) to provide for term loans replacing all or a portion of the Term Facilities, subject to customary limitations, with the consent of the
Administrative Agent, the Borrower and the Lenders providing such replacement term loans and, in connection with any of the foregoing, the right of the Borrower to prepay the outstanding loans, terminate the commitments or require the applicable
Lenders to assign their Term Loans to the providers of any replacement credit facility or loans.
		
	 Yield Protection:
	  	The Senior Facilities will contain customary provisions (a) protecting the Lenders against increased costs or loss of yield resulting from changes in reserve, capital adequacy and
capital requirements (or their interpretation), illegality, unavailability and other requirements of law and from the imposition of or changes in certain withholding or other taxes and (b) indemnifying the Lenders for “breakage costs”
incurred in connection with, among other things, any prepayment of a Eurodollar Rate loan on a day other than the last day of an interest period with respect thereto. For all purposes of the Loan Documents, (i) the Dodd-Frank Wall Street Reform and
Consumer Protection Act and all requests, rules, guidelines and directives promulgated thereunder and (ii) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking
Supervision (or any successor or similar authority) or the United States regulatory authorities, in each case, pursuant to Basel III, shall be deemed introduced or adopted after the date of the Loan Documents. The Senior Facilities will provide that
all payments are to be made free and clear of any taxes (other than franchise taxes and taxes on overall net income), imposts, assessments, withholdings or other deductions whatsoever. Lenders will furnish to the Administrative Agent appropriate
certificates or other evidence of exemption from U.S. federal tax withholding (with customary exceptions for FATCA).
		
	 Indemnity:
	  	The Senior Facilities will provide customary and appropriate provisions relating to indemnity and related matters in a form reasonably satisfactory to the Arranger, the
Administrative Agent and the Lenders.
		
	 Governing Law and Jurisdiction:
	  	The Senior Facilities will provide that the Borrower will submit to the exclusive jurisdiction and venue of the federal and state courts of the State of New York (except to the
extent the Collateral Agent (to be defined in the Loan Documents) requires submission to any other jurisdiction in connection with the exercise of any rights under any security document or the enforcement of any judgment) and will waive any right to
trial by jury. New York law will govern the Loan Documents, except with respect to certain security documents where applicable local law is necessary for enforceability or perfection.

capitalized terms used herein are defined in the Commitment Letter. 
  

			
	Borrower:	  	Hologic, Inc. (the “Borrower”).
		
	 Guarantors:
	  	Each of the Guarantors under the Senior Facilities (collectively, the “Guarantors”) will guarantee (the “Guarantee”) all obligations under the
Bridge Loans. The Bridge Loans and the Guarantee will rank pari passu in right of payment with the Senior Facilities and all other senior indebtedness and guarantees of such indebtedness of the Borrower and the Guarantors (including, without
limitation, the Acquired Business), if any.
		
	 Sole Lead Arranger, Sole Bookrunner and Sole Syndication Agent:
	  	Goldman Sachs Lending Partners LLC (“Goldman Sachs”, in its capacities as Sole Lead Arranger, Sole Bookrunner and Sole Syndication Agent, the
“Arranger”).
		
	 Administrative Agent:
	  	Goldman Sachs (in its capacity as Administrative Agent, the “Bridge Administrative Agent”).
		
	 Lenders:
	  	Goldman Sachs and/or other financial institutions selected by Goldman Sachs (each, a “Lender” and, collectively, the
“Lenders”).
		
	 Amounts of Bridge Loans:
	  	$500 million in aggregate principal amount of senior increasing rate loans, less the amount of gross proceeds from any sale of Notes (or other Permanent Debt) received on or
prior to the Closing Date (the “Bridge Loans”).
		
	 Closing Date:
	  	The date on which borrowings under the Senior Facilities are made (the “Closing Date”).
		
	 Ranking:
	  	The Bridge Loans, the Guarantee and all obligations with respect thereto will be unsecured and rank pari passu in right of payment with all obligations of the Borrower under the
Senior Facilities.
		
	 Security:
	  	Not applicable.
		
	 Maturity:
	  	The Bridge Loans will mature on the 7-year anniversary of the Closing Date. At any time and from time to time, on or after the first anniversary of the Closing Date, upon
reasonable prior written notice and in a minimum principal amount of at least $50 million in the aggregate principal amount of Exchange Notes, the Bridge Loans may be exchanged (each such exchange, an “Exchange”), in whole or
in part, at the option of the applicable Lender, for Senior Exchange Notes (the “Exchange Notes”), in a principal amount equal to the principal

  
 Annex C-1

			
		  	amount of the Bridge Loans so exchanged and having the same maturity date as the Bridge Loans so exchanged. Each Exchange shall be made pursuant to surrender and issuance
arrangements to be set forth in the definitive documents for the Bridge Loans and each holder of Bridge Loans requesting such an exchange shall be required to make customary representations and warranties in connection therewith, all in form and
substance, reasonably satisfactory to the Arranger, the Bridge Administrative Agent and Borrower.
		
		  	The Exchange Notes will be issued pursuant to an indenture (the “Indenture”) that will have the terms set forth on Exhibit 1 to this
Annex C.
		
	 Interest Rate:
	  	Until the earlier of (i) the first anniversary of the Closing Date and (ii) the occurrence of a Demand Failure Event (as defined in the Fee Letter) (such earlier date, the
“Conversion Date”), the Bridge Loans will bear interest at a floating rate, reset quarterly, as follows: (i) for the first three-month period commencing on the Closing Date, the Bridge Loans will bear interest at a rate per
annum equal to the reserve adjusted Eurodollar Rate, plus the margin per annum set forth in the table below opposite the applicable Rating Level as of the Closing Date (collectively, the “LIBOR Rate”), and (ii)
thereafter, interest on the Bridge Loans will be payable at a floating per annum rate reset at the beginning of each subsequent three-month period, equal to the LIBOR Rate as of such reset date plus the Spread. The “Spread” will
initially be 50 basis points (commencing three months after the Closing Date) and will increase by an additional 50 basis points every three months thereafter. Notwithstanding the foregoing, at no time will the per annum interest rate on the Bridge
Loans exceed the Total Cap then in effect, as defined in the Fee Letter (plus default interest, if any).

  

							
	 	 	Rating Level	  	Margin	 
	 	 Level I
	  	 	5.75	% 
	 	 Level II
	  	 	6.00	% 
	 	 Level III
	  	 	6.25	% 

  

			
		  	From and after the Conversion Date, the Bridge Loans will bear interest at a fixed rate equal to the Total Cap (plus default interest, if any).
		
		  	Prior to the Conversion Date, interest will be payable at the end of each interest period. Accrued Interest shall also be payable in arrears on the Conversion Date and on the
date of any prepayment of the Bridge Loans. From and after the Conversion Date, interest will be payable quarterly in arrears and on the date of any prepayment of the Bridge Loans.

  
 Annex C-2

			
		  	As used herein, the term “reserve adjusted Eurodollar Rate” will have the meaning customary and appropriate for financings of this type, and the basis for
calculating accrued interest and the interest periods for loans bearing interest at the reserve adjusted Eurodollar Rate will be customary and appropriate for financings of this type subject to a reserve adjusted Eurodollar Rate “floor” of
1.25%.
		
		  	After the occurrence and during the continuance of an Event of Default, interest on overdue amounts will accrue at a rate equal to the applicable rate set forth above, plus an
additional two percentage points (2.00%) per annum and will be payable on demand.
		
	 Mandatory Prepayment:
	  	Prior to the Conversion Date, the net proceeds to the Borrower or any subsidiary of the Borrower (including, without limitation, the Acquired Business) from (a) any direct
or indirect public offering or private placement of any debt or equity securities (other than issuances pursuant to employee stock plans), (b) any future bank borrowings other than under the Senior Facilities as in effect on the Closing Date
and (c) any future asset sales or receipt of insurance proceeds (subject to certain ordinary course exceptions) will be used to repay the Bridge Loans subject, in the case of clauses (b) and (c) only, to the required prior repayment of any
amount then outstanding under the Senior Facilities, in each case, at 100% of the principal amount of the Bridge Loans prepaid plus accrued interest to the date of prepayment; provided that in the case of an issuance of Permanent Debt
(with such proceeds being applied to repay the Bridge Loans prior to the repayment of loans outstanding under the Senior Facilities) to any Lender (or any of its affiliates) or any person to whom a Lender participated an interest in the Bridge Loans
(or any of such participant’s affiliates) (such Lenders, participants and affiliates, “Specified Bridge Parties”), the net cash proceeds received by the Company and its affiliates in respect of such Permanent Debt acquired by
such Specified Bridge Parties may, at the option of such Specified Bridge Party, be applied first to prepay the Bridge Loans of such Specified Bridge Party prior to being applied to prepay the Bridge Loans held by other Lenders on a pro rata
basis.
		
		  	From and after the Conversion Date, the mandatory prepayment provisions in the definitive documentation governing the Bridge Loans (the “Bridge Loan Agreement”)
will be automatically amended to require that the Borrower prepay the outstanding Bridge Loans, on a pro rata basis, at par plus accrued interest to the date of prepayment with the proceeds of any future asset sales (subject to any required
prepayments of the Senior Facilities with such proceeds, certain ordinary course exceptions and customary reinvestment rights within 365 days); provided that, each holder of Bridge Loans may elect to reject its pro rata share of such
prepayment such holder is otherwise entitled to receive pursuant to this paragraph.

  
 Annex C-3

			
		  	Nothing in these mandatory prepayment provisions will restrict or prevent any holder of Bridge Loans from exchanging Bridge Loans for Exchange Notes on or after the first
anniversary of the Closing Date.
		
	 Change of Control:
	  	Upon the occurrence of a Change of Control (to be defined in the Bridge Loan Agreement), the Borrower will be required to repay all obligations under the Senior Facilities (or
obtain any required consent of the lenders under the Senior Facilities to make such prepayment of the Bridge Loans) and deposit in escrow an amount necessary to prepay in full all outstanding Bridge Loans, which amount shall be prepaid 30 days after
the Change of Control, at par plus accrued interest to the date of prepayment, plus with respect to any Bridge Loans so prepaid on or after the Conversion Date, a 1.00% prepayment premium.
		
	 Voluntary Prepayment:
	  	Prior to the Conversion Date, Bridge Loans may be prepaid, in whole or in part, at the option of the Borrower, at any time (except as provided below) without premium or penalty,
upon five business days’ written notice, such prepayment to be made at par plus accrued interest.
		
		  	From and after the Conversion Date, Bridge Loans may be prepaid, in whole or in part, at the option of the Borrower, at any time (except as provided below) upon 30 days prior
written notice at par plus accrued interest to the date of repayment plus the Applicable Premium. The “Applicable Premium” will be (i) a make-whole premium based on the applicable treasury rate plus 50 basis points during the first
three years following the Closing Date and (ii) 75% of the interest rate on the Bridge Loans in year four following the Closing Date declining ratably on each subsequent anniversary of the Closing Date to zero one year prior to the maturity of the
Bridge Loans (it being understood and agreed that, for the avoidance of doubt, the Applicable Premium will not be payable in connection with an Exchange).
		
		  	The Borrower may not make any optional prepayment of Bridge Loans (i) during the period commencing on the date of a Permanent Debt Notice (as defined in the Fee Letter) and
ending upon the earliest of (x) the consummation of an issuance or incurrence of Permanent Debt in accordance with such Permanent Debt Notice, (y) the withdrawal or termination of such Permanent Debt Notice and (z) the first business day following
the Conversion Date or (ii) to the extent that the holder thereof has given notice to the Borrower of its intent to elect to exchange Bridge Loans for Exchange Notes during the period commencing on the delivery of the related notice and ending
upon the withdrawal of such notice or the consummation of the exchange of such holder’s Bridge Loans for Exchange Notes.
		
	 Representations and Warranties:
	  	The Bridge Loan Agreement will contain customary and appropriate representations and warranties by the Borrower (with respect to the Borrower and its subsidiaries), based on the
Tranche B Term Facility’s representations and warranties.

  
 Annex C-4

			
	Covenants:	  	The Bridge Loan Agreement will contain customary and appropriate covenants by the Borrower (with respect to the Borrower and its subsidiaries), based on the Tranche B Term
Facility’s covenants but more restrictive in certain respects prior to the Conversion Date, and with such changes as are appropriate in connection with the Bridge Loans and including, without limitation, a covenant to comply with Section 3 of
the Commitment Letter, the Fee Letter and the engagement letter of even date herewith between the Company and the financial institution or financial institutions party thereto (collectively, the “Financial Institution”) (the
“Engagement Letter”), and to use commercially reasonable efforts to refinance the Bridge Loans as promptly as practicable following the Closing Date. The Bridge Loan Agreement shall not contain any financial (maintenance)
covenants.
		
	 Events of Default:
	  	Prior to the Conversion Date, the Bridge Loan Agreement will include customary and appropriate events of default (and, as appropriate, grace periods) based on the Tranche B Term
Facility’s events of default (other than with respect to Change of Control), including an event of default for failure to comply with Section 3 of the Commitment Letter, the Fee Letter and the Engagement Letter and defaults under other debt
(including the Senior Facilities). From and after the Conversion Date, the events of default in the Bridge Loan Agreement will be limited to failure to pay principal or interest, defaults under other debt agreements that result in the acceleration
of other indebtedness prior to its stated maturity, inaccuracy of representatives and warranties noncompliance with covenants in the Bridge Loan Agreement, judgments in excess of certain specified amounts, invalidity of guarantees, failure to comply
with Section 3 of the Commitment Letter, the Fee Letter or the Engagement Letter and certain bankruptcy and related events, in each case subject to materiality thresholds and grace periods where customary and appropriate.
		
	 Conditions Precedent to Borrowing:
	  	The several obligations of the Lenders to make, or cause one of their respective affiliates to make, the Bridge Loans will be subject to the conditions precedent referred to in
Section 2 of the Commitment Letter, prior written notice of borrowing and the accuracy of the representations and warranties set forth in the second paragraph of Section 2 of the Commitment Letter in all material respects (except to the extent that
such representation or warranty is already qualified by “materiality,” “material adverse effect” or similar language, in which case such representation and warranty shall be true and correct in all respects).
		
	 Assignments and Participations:
	  	Each of the Lenders may assign all or (subject to minimum assignment amount requirements) any part of its Bridge Loans to its affiliates (other than natural persons) or one or
more banks, financial institutions or other entities that are “Eligible Assignees,” as defined in the Bridge Loan Agreement, that (except in the case of assignments made to Goldman Sachs) are reasonably acceptable to the
Bridge

  
 Annex C-5

			
		  	Administrative Agent, such consent not to be unreasonably withheld or delayed; provided that, prior to the Conversion Date, the consent of the Borrower shall be required
with respect to any assignment if, subsequent thereto, Goldman Sachs and the Additional Agents with respect to the Bridge Loans (and each of their subsidiaries) would hold, in the aggregate, less than 50.1% of the Bridge Loans.
		
		  	Upon such assignment, such Eligible Assignee will become a Lender for all purposes under the Bridge Loan Agreement; provided that assignments made to affiliates and
other Lenders will not be subject to the above described consent or any minimum assignment amount requirements. A $3,500 processing fee will be required in connection with any such assignment (except in the case of assignments made by or to Goldman
Sachs). The Lenders will also have the right to sell participations, without restriction, subject to customary limitations on voting rights, in their respective Bridge Loans.
		
	 Requisite Lenders:
	  	Amendments and waivers will require the approval of Lenders holding more than 50% of the Bridge Loans then outstanding (“Requisite Lenders”),
provided that, in addition to the approval of Requisite Lenders, no amendment may (i) extend the maturity of any Bridge Loan or change the time of payment of interest on any Bridge Loan, (ii) reduce the rate of interest or the
principal amount of any Bridge Loan, (iii) alter the prepayment provisions of any Bridge Loan or (iv) reduce the percentage of holders necessary to modify or change the Bridge Loans, in each case without the consent of each Lender affected
thereby.

third party designated by it, upon surrender by the Lender to the Borrower of an equal principal amount of Bridge Loans. No Exchange Notes will be issued until the Borrower receives requests to issue at least $50 million in aggregate principal
amount of Exchange Notes. The Borrower will issue Exchange Notes under an indenture (the “Indenture”) that complies with the Trust Indenture Act of 1939, as amended. The Borrower will appoint a trustee reasonably acceptable to the

		  	After the occurrence and during the continuance of any Event of Default, interest on overdue amounts will accrue at the applicable rate plus two percentage points (2.00%) per
annum.
		
	 Optional Redemption:
	  	Until the third anniversary of the Closing Date, each Exchange Note will only be callable at par plus accrued interest to the date of repayment plus the Applicable Premium. The

	  	The Borrower will file within 90 days after the first anniversary of the Closing Date and will use its best efforts to cause to become effective as soon thereafter as
practicable, a shelf registration statement with respect to the Exchange Notes (a “Shelf Registration Statement”). If a Shelf Registration Statement is filed, the Borrower will keep such registration statement effective and
available (subject to customary exceptions); provided that after a Shelf Registration Statement has been declared effective, the Borrower will be permitted to permit its effectiveness to lapse if it is no longer needed to permit unrestricted
resales of all of the Exchange Notes. If within 180 days after the first anniversary of the Closing Date (the “Effectiveness Deadline”) a Shelf Registration Statement for the Exchange Notes has not been declared effective, then the
Borrower will pay liquidated damages in the form of increased interest of 25 basis points per annum on the principal amount of Exchange Notes and Bridge Loans outstanding to holders of such Exchange Notes and Bridge Loans from and including the
Effectiveness Deadline to but excluding the effective date of such Shelf Registration Statement. On the 90th day after the Effectiveness Deadline, the liquidated damages will increase by 25 basis points per annum, and on each 90-day
anniversary of the Effectiveness Deadline thereafter, will increase by 25 basis points per annum, to a maximum increase in interest of 100 basis points per annum. The Borrower will also pay such special interest for any period of time
(subject to customary exceptions) following the effectiveness of a Shelf Registration Statement that such Shelf Registration Statement is not available for sales thereunder. All accrued special interest will be paid on each semiannual interest
payment date. Any registration rights agreement and related documents shall be on customary terms to be mutually agreed.
		
	 Covenants:
	  	The indenture relating to the Exchange Notes will include covenants similar to those contained in an indenture governing publicly traded high yield debt securities. The Exchange
Notes shall not contain any financial (maintenance) covenants.
		
	 Events of Default:
	  	The indenture relating to the Exchange Notes will provide for Events of Default similar to those contained in an indenture governing publicly traded high yield debt
securities.

 The foregoing is intended to summarize certain basic terms of the Exchange Notes. It is not intended to be a
definitive list of all of the requirements of the Lenders in connection with the Exchange Notes.
