Purchase Agreement

On March 14, 2019, Endo International plc (“Endo”) entered into a purchase agreement (the “Purchase Agreement”) among Par Pharmaceutical, Inc. (the “Issuer”), the other guarantors party thereto (the “Guarantors”) and J.P. Morgan Securities LLC as representative (the “Representative”) of the several initial purchasers named therein (collectively, the “Initial Purchasers”), in connection with the Issuer’s offering of $1.5 billion aggregate principal amount of 7.500% Senior Secured Notes due 2027 (the “Notes”) issued under an indenture to be entered into among Endo, the Issuer, the Guarantors and Wells Fargo, National Association, as trustee, which represents an upsize of $500.0 million over the previously contemplated offering amount.

The Notes will be guaranteed by Endo and certain of its subsidiaries and will be secured by first priority liens on the same collateral that secures Endo’s obligations under its existing senior secured credit facilities and existing senior secured notes.

The Notes and the related guarantees have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), or any applicable state or foreign securities laws, and will be offered only to qualified institutional buyers in reliance on Rule 144A, and to persons outside the United States in compliance with Regulation S under the Securities Act.

Endo intends to use the net proceeds from the offering, together with cash on hand, to fund the Tender Offers (as defined below) by Endo Finance LLC, a wholly-owned subsidiary of Endo, to purchase a portion of Endo’s outstanding senior unsecured notes and to pay certain related premiums, fees and expenses. Endo intends to use the remaining net proceeds, if any, from this offering to reduce Endo’s outstanding indebtedness, including by means of one or more redemptions, repurchases or other repayments of any of Endo’s outstanding indebtedness. The offering is not conditioned upon the consummation of the Tender Offers and related consent solicitations.

The Purchase Agreement includes customary representations, warranties and covenants by Endo, the Issuer and the Guarantors. Under the terms of the Purchase Agreement, Endo, the Issuer and the Guarantors have agreed to indemnify the Initial Purchasers against certain liabilities. The offering of the Notes is expected to close on or about March 28, 2019.

Certain of the initial purchasers and their affiliates have engaged, and may in the future engage, in investment banking, commercial banking and other financial advisory and commercial dealings with the Issuer and its affiliates. In particular, certain of the initial purchasers and/or their affiliates are holders of Endo’s outstanding indebtedness and, therefore, may receive a portion of the proceeds of this offering. Affiliates of J.P. Morgan Securities LLC are lenders and agents under Endo’s existing senior secured credit facilities.

Pricing of Notes

On March 14, 2019, Endo announced the pricing of the Notes. A copy of the related press release is filed herewith as Exhibit 99.1 and is incorporated herein by reference.

Upsizing of Tender Offers

In connection with upsizing of the aggregate principal amount of the Notes in connection with the offering by the Issuer as described above, Endo Finance LLC, a wholly-owned subsidiary of Endo, announced an upsizing of the previously announced cash tender offers (the “Tender Offers”) and consent solicitations to increase (i) the aggregate purchase price from the initial amount of $1.0 billion to $1.5 billion for all of the notes validly tendered and not validly withdrawn in the Tender Offers and (ii) the acceptance sublimit applicable to certain series of such notes from $500.0 million to $650.0 million. All other terms of the Tender Offers and the related consent solicitations, as previously announced, remain unchanged.

A copy of the related press release is filed herewith as Exhibit 99.2 and is incorporated herein by reference.

Forward-Looking Statements

This press release contains forward-looking statements including, but not limited to, Endo’s financing plans, including those related to the notes offering, the Tender Offers and the details thereof and the use of proceeds from the notes offering. Endo has tried, whenever possible, to identify such statements by words such as “believes,” “expects,” “anticipates,” “intends,” “estimates,” “plan,” “projected,” “forecast,” “will,” “may” or similar expressions. Endo has based these forward-looking statements on its current expectations and projections about the growth of its business and financial performance, and the development of its industry. Because these statements reflect Endo’s current views concerning future events, these forward-looking statements involve risks and uncertainties. Readers should note that many risk factors previously disclosed in Endo’s filings with the Securities and Exchange Commission (the “SEC”) and those identified elsewhere in this press release could affect Endo’s future financial results and could cause the actual results to differ materially from those expressed in forward-looking statements contained in this press release.

Endo does not undertake any obligation to update its forward-looking statements after the date of this press release for any reason, even if new information becomes available or other events occur in the future, except as required under applicable securities law. Readers are advised to consult any further disclosures made on related subjects in Endo’s reports filed with the SEC. Also note that, as described under the caption “Risk Factors” contained in

Item 1A of the Endo’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, Endo provides a cautionary discussion of the risks, uncertainties and possibly inaccurate assumptions relevant to its business. These are factors that, individually or in the aggregate, Endo thinks could cause its actual results to differ materially from expected and historical results. Readers should understand that it is not possible to predict or identify all such factors. Consequently, readers should not consider this to be a complete discussion of all potential risks or uncertainties.

Investors should also be aware that while Endo does, at various times, communicate with securities analysts, it is against Endo’s policy to disclose to them selectively any material non-public information or other confidential information. Accordingly, investors should not assume that Endo agrees with any statement or report issued by an analyst, irrespective of the content of the statement or report. To the extent that reports issued by securities analysts contain any projections, forecasts or opinions, such reports are not Endo’s responsibility.

Exhibit 99.2

Endo International plc Announces an Upsizing of its Cash Tender Offers and Consent Solicitations

DUBLIN, March 14, 2019 – Endo International plc (NASDAQ: ENDP) today announced an upsizing of its previously announced cash tender offers (the “Tender Offers”) and consent solicitations by Endo Finance LLC (“Endo Finance”), a wholly-owned subsidiary of Endo International plc. Endo Finance amended the Tender Offers to increase (i) the Aggregate Purchase Price (as defined below) from the initial amount of $1.0 billion to $1.5 billion for all of the Notes (as defined below) validly tendered and not validly withdrawn in the Tender Offers and (ii) the Acceptance Sublimit (as defined below) from the initial aggregate amount of $500.0 million to $650.0 million. All other terms of the Tender Offers and the related consent solicitations, as previously announced, remain unchanged.

The Tender Offers will be in an amount such that the maximum aggregate consideration (excluding accrued interest) paid by Endo Finance does not exceed the increased amount of $1.5 billion (subject to further increase by Endo Finance, the “Aggregate Purchase Price”), of the outstanding

subject to the Acceptance Priority Levels, the Aggregate Purchase Price and the Acceptance Sublimit described below.

The terms and conditions of the Tender Offers are described in Endo Finance’s Offer to Purchase and Consent Solicitation, dated March 14, 2019 (the “Offer to Purchase”), as amended on the date hereof, and the related Letter of Transmittal and Consent. The Tender Offers are conditioned, among other conditions set forth in the Offer to Purchase, upon the Company having received gross proceeds of an aggregate principal amount of at least $1.0 billion (the “financing condition”) from one or more issuances of secured indebtedness in the capital markets and/or from borrowings under the Company’s existing credit facilities. The Company’s ability to raise additional proceeds from one or more issuances of secured indebtedness will be dependent on then prevailing market conditions and other factors. Each of the Tender Offers is a separate offer (each, an “Offer”), and, subject to applicable law, each Offer may be individually amended, extended or terminated.

The following table summarizes certain material terms for the Tender Offers:

In conjunction with the Tender Offers, Endo Finance is soliciting consents (the “Consent Solicitations”) from holders of the Consent Notes to certain proposed amendments (the “Proposed Amendments”) to the applicable indenture under which such series of Consent Notes were issued (each an “Indenture” and collectively, the “Indentures”), which would eliminate substantially all restrictive covenants, certain events of default and certain other provisions contained in each such Indenture. The adoption of the Proposed Amendments with respect to each series of Consent Notes requires the consent of the holders of at least a majority of the outstanding principal amount of each such series of Consent Notes (with respect to each series of Consent Notes, collectively, the “Requisite Consents”). Each tendering holder of the Consent Notes will be deemed to have consented to all of the Proposed Amendments as to the Consent Notes of the applicable series of Consent Notes tendered. If Endo Finance receives the Requisite Consents, it will execute a supplemental indenture to the applicable Indenture with respect to a series of Consent Notes under which Consent Notes of such series were issued (each a “Supplemental Indenture” and collectively the “Supplemental Indentures”). Each Supplemental Indenture will become effective upon execution thereof by Endo Finance, the co-issuer (as applicable), the guarantors thereto and Wells Fargo Bank, National Association, the trustee for each series of Consent Notes (the “Trustee”), but each Supplemental Indenture will provide that the Proposed Amendments with respect to a series of Consent Notes will not become operative until Endo Finance purchases in the Tender Offers at least a majority in principal amount of the outstanding applicable series of Consent Notes. Endo Finance may, in its sole discretion, complete Tender Offers for any series of Consent Notes even if valid consents sufficient to effect the Proposed Amendments to the corresponding Indenture are not received. If the Tender Offer for either series of Consent Notes is terminated, withdrawn or consummated without the Requisite Consents, the applicable Indentures will remain in effect in its present form. In the event of any proration of any series of Consent Notes, the Consents delivered with respect to such series of Consent Notes shall be null and void, but the validity of such Consent Notes tendered shall be unaffected.

Each of the Tender Offers and Consent Solicitations will expire at 11:59 P.M., New York City time, on April 10, 2019, unless extended (such date and time, as it may be extended, the “Expiration Date”) or earlier terminated by Endo Finance in accordance with the terms of the Offer to Purchase. No tenders submitted after the Expiration Date will be valid.

With respect to the 2023 Notes, tendered Notes may be validly withdrawn from the Tender Offer at or prior to, but not after 5:00 p.m., New York City time, on March 27, 2019 (such date and time, as it may be extended, the “Early Tender Date”). With respect to the Consent Notes, tendered Notes may be validly withdrawn (and Consents validly revoked) from the applicable Tender Offer, at or prior to, but not after, the date the applicable Supplemental Indenture is executed. In the case of each of the 2023 Notes and the Consent Notes, such date and time, as it may be extended, is referred to as the “Withdrawal Deadline.” Holders who tender their Notes after the Withdrawal Deadline, but prior to the Expiration Date, may not withdraw their tendered Notes unless withdrawal rights are required to be extended pursuant to applicable law.

2

Subject to the terms and conditions of the Tender Offers and Consent Solicitations, holders who validly tender, and do not validly withdraw, their Notes at or prior to the Early Tender Date, and whose Notes are accepted for purchase, will receive the applicable total consideration set forth in the table above for each $1,000 principal amount of Notes purchased pursuant to the Tender Offers (the “Total Consideration”), which includes the early tender premium set forth in the table above per $1,000 principal amount of Notes (the “Early Tender Premium”). Subject to the terms and conditions of the Tender Offers and Consent Solicitations, holders who validly tender their Notes after the Early Tender Date and at or prior to the Expiration Date, and whose Notes are accepted for purchase, will receive only the applicable tender offer consideration amount set forth in the table above for each $1,000 principal amount of Notes purchased pursuant to the Tender Offers (the “Tender Offer Consideration”), which is equal to the applicable Total Consideration minus the Early Tender Premium. In addition to the applicable Total Consideration or the Tender Offer Consideration, as the case may be, all holders of Notes accepted for purchase pursuant to the Tender Offers will also receive on the Early Settlement Date (as defined below), if any, or the Final Settlement Date (as defined below), as applicable, accrued and unpaid interest on their Notes purchased from the applicable last interest payment date with respect to such Notes up to, but not including, the Early Settlement Date or the Final Settlement Date, as applicable.

The Notes accepted for purchase will be accepted in accordance with their Acceptance Priority Levels set forth in the table above (with 1 being the highest Acceptance Priority Level), provided that (a) Endo Finance will only accept for purchase Notes of any and all series up to an amount such that the aggregate amount of Total Consideration and/or Tender Offer Consideration, as the case may be, paid by Endo Finance pursuant to the Tender Offers will not exceed the Aggregate Purchase Price, (b) Endo Finance will not purchase an aggregate amount of 2023 Notes such that the aggregate purchase price for such 2023 Notes is in excess of the acceptance sublimit applicable to such series as set forth in footnote 4 to the table above (the “Acceptance Sublimit”), and (c) Notes tendered and not validly withdrawn at or prior to the Early Tender Date will be accepted for purchase in priority to Notes tendered after the Early Tender Date and at or prior to the Expiration Date. Endo Finance reserves the right, but is under no obligation, to increase the Aggregate Purchase Price and/or the Acceptance Sublimit or to otherwise alter the terms of any Tender Offer at any time, subject to compliance with applicable law, which could result in Endo Finance purchasing a greater aggregate principal amount of any or all series of Notes in the Tender Offers.

Subject to the terms and conditions of the Tender Offers and Consent Solicitations, Endo Finance will have the option, but not the obligation, to accept for purchase and purchase, subject to the Aggregate Purchase Price and the applicable Acceptance Sublimit (if any), any Notes validly tendered and not validly withdrawn at or prior to the Early Tender Date on the early settlement date (the “Early Settlement Date”), which may occur no earlier than March 29, 2019. To the extent that Endo Finance does not elect early settlement or to the extent early settlement is elected but the Tender Offers are not fully subscribed at the Early Tender Date, Endo Finance expects to purchase Notes that have been validly tendered in accordance with the terms and conditions of the Tender Offers and Consent Solicitations, promptly following the Expiration Date (the “Final Settlement Date”), which is currently expected to occur on April 12, 2019. Notes accepted on any Early Settlement Date or the Final Settlement Date will be accepted subject to the Aggregate Purchase Price, the Acceptance Priority Levels, the applicable Acceptance Sublimit (if any) and proration, each as described in the Offer to Purchase. If the aggregate purchase price of the 2023 Notes validly tendered and not validly withdrawn exceeds the Acceptance Sublimit, the 2023 Notes purchased will be subject to proration based on the Acceptance Priority Levels for the 2023 Notes and the aggregate purchase price of 2023 Notes tendered in the Offer, provided that subject to the Acceptance Priority Levels for the 2023 Notes, any 2023 Notes tendered at or prior to the Early Tender Date will be accepted for purchase in priority to 2023 Notes tendered after the Early Tender Date and at or prior to the Expiration Date and if the Acceptance Sublimit for the 2023 Notes is exceeded at the Early Tender Date, the 2023 Notes tendered at or prior to the Early Tender Date shall constitute a separate proration pool.

The Tender Offers are subject to the satisfaction or waiver of certain conditions to the Tender Offers set forth in the Offer to Purchase, including the financing condition.
