Any Class that, as of the commencement of the Combined Hearing, does not have at least one Holder of a Claim or Interest that is Allowed in an amount greater than zero for voting purposes shall be considered vacant, deemed eliminated from this Plan for purposes of voting to accept or reject this Plan, and disregarded for purposes of determining whether this Plan satisfies section 1129(a)(8) of the Bankruptcy Code with respect to such Class.

The Debtors assert that only Classes of Interests in Class 6 are impaired and entitled to vote to accept or reject the Plan.

With respect to each Debtor, if a Class contained Claims eligible to vote and no Holder of Claims or Interests eligible to vote in such Class votes to accept or reject this Plan, this Plan shall be presumed accepted by the Holders of such Claims or Interests in such Class.

If a controversy arises as to whether any Claim or any Class of Claims is Impaired, the Bankruptcy Court shall, after notice and a hearing, determine such controversy on or before the Combined Hearing.

The allowance, classification, and treatment of all Allowed Claims and Interests and the respective distributions and treatments under the Plan shall take into account and conform to the relative priority and rights of the Claims and Interests in each Class in connection with any contractual, legal, and equitable subordination rights relating thereto, whether arising under general principles of equitable subordination, contract, section 510(b) of the Bankruptcy Code, or otherwise.

The Liquidating Trust shall be a legally separate and distinct Entity from the Debtors and the Plan Administrator.

2. Liquidating Trustee

The Liquidating Trust shall be controlled and administered by the Liquidating Trustee, subject to the oversight and direction of the Liquidating Trust Oversight Committee. The Debtors and the Plan Administrator shall have no direct or indirect control, influence, or authority over the Liquidating Trust, the Liquidating Trustee, or the Liquidating Trust Oversight Committee or any of their respective decisions, except as expressly set forth in this Plan.

The Liquidating Trustee, subject to the oversight of the Liquidating Trust Oversight Committee, shall have the exclusive control over all aspects of the Retained Causes of Action that shall vest in the Liquidating Trust (as set forth in the Schedule of Retained Causes of Action), including the investigation, prosecution, and disposition of the same in accordance with the terms of the Liquidating Trust Agreement.

It is intended that the Liquidating Trust qualify as a “liquidating trust” within the meaning of Treasury Regulations Section  ###-###-####-4(d). In general, a liquidating trust is not a separate taxable entity but rather is treated for U.S. federal income tax purposes as a “grantor” trust (i.e., a pass-through entity). The IRS, in Revenue Procedure 94-45, 1994-2 C.B. 684, set forth the general criteria for obtaining an IRS ruling as to the grantor trust status of a liquidating trust under a chapter 11 plan. The Liquidating Trust will be structured with the intention of complying with such general criteria. Pursuant to the Plan, and in conformity with Revenue Procedure 94-45, all parties (including the Liquidating Trustee and holders of beneficial interests in the Liquidating Trust) are required to treat for U.S. federal income tax purposes the Liquidating Trust as a grantor trust of which such holders of beneficial interest are the owners and grantors. The Liquidating Trustee is hereby appointed in such instance pursuant to section 1123(b)(3)(B) of the Bankruptcy Code to handle all of the Liquidating Trust’s tax matters, including, without limitation, the filing of all tax returns and the handling of tax audits and proceedings of the Liquidating Trust. Notwithstanding the foregoing, the Liquidating Trustee may make an election under Treasury Regulations Section 1.468B-0(c)(2)(ii) to treat the Liquidating Trust (or any potion thereof) as a disputed ownership fund. The Liquidating Trustee shall be responsible of filing information on behalf of the Liquidating Trust as a grantor trust pursuant to Treasury Regulation Section 1.671-4(a) or as a disputed ownership fund.

1.Continued Corporate Existence

(a) Each of the Debtors shall remain in existence unless and until dissolved by Plan Administrator in accordance with the provisions of this Plan.

(b) On the Effective Date or as soon as reasonably practicable thereafter, in connection with the assignment of the Retained Causes of Action that shall vest in the Liquidating Trust (as set forth in the Schedule of Retained Causes of Action), at the discretion of the Liquidating Trustee, one percent (1%) of an Intercompany Interest of any Debtor shall be

Exhibit A  Page 30 of 58

transferred to the Liquidating Trustee to confer standing upon the Liquidating Trustee to institute litigation respecting Retained Causes of Action on behalf of the Debtors pursuant to the provisions of any applicable LLC Act. For the avoidance of doubt, the 1% Intercompany Interest transferred to the Liquidating Trust pursuant to this Plan shall not confer any voting or other rights to the Liquidating Trustee other than for the purpose of conferring exclusive derivative standing upon the Liquidating Trustee as described herein.

(c) The Plan Administrator shall give the Liquidating Trustee forty-five (45) days written notice (the “Termination Notice”) of its intentions to merge, dissolve, or otherwise terminate the existence of a Wind-Down Debtor. Upon receipt of the Termination Notice, the Liquidating Trustee will evaluate whether prosecution of a pending or contemplated Retained Cause of Action necessitates the continued corporate existence of a Wind-Down Debtor, in which case the Plan Administrator shall take no action with respect to merging, dissolving, or otherwise terminating the existence of such Wind-Down Debtor until such litigation claim is resolved by the Liquidating Trust; provided, however, that all costs (including the fees of the Plan Administrator) associated with maintaining the continued corporate existence of any such Wind-Down Debtor beyond forty-five (45) days from the delivery of the Termination Notice shall be borne by the Liquidating Trustee.

(d) As of the Effective Date, the certificate of incorporation, bylaws, articles of organization, certificate of formation, or limited liability company operating agreement, as applicable, of each Debtor shall be deemed amended to the extent necessary to carry out the provisions of the Plan. The entry of the Confirmation Order shall constitute authorization for the Debtors, the Wind-Down Debtors, the Plan Administrator, and the Liquidating Trustee, as applicable, to take or cause to be taken all actions (including, if applicable, corporate actions) necessary or appropriate to implement all provisions of, and to consummate, the Plan prior to, on, and after the Effective Date and all such actions taken or caused to be taken shall be deemed to have been authorized and approved by the Bankruptcy Court without further approval, act, or action under any applicable law, order, rule, or regulation.

(e) To the extent that it is determined that additional corporate governance or structural changes may be required to confer standing on the Liquidating Trustee with respect to any Retained Causes of Action, the Plan Administrator will exercise reasonable efforts to cooperate and work with the Liquidating Trustee to achieve and confer such standing so long as any proposed governance or structural changes requested by the Liquidating Trustee do not interfere with the Plan Administrator’s ability to carry out its own functions and responsibilities.

(f) Tax Reporting

The Plan Administrator shall file any and all tax returns for the Wind-Down Debtors and the Estates, as applicable; provided, however, that the Plan Administrator shall have no personal liability for the signing or accuracy of the Debtors’ tax returns that are due to be filed after the Effective Date or for any tax liability related thereto.

The Plan Administrator shall be responsible for payment, out of the Wind-Down Budget, of any taxes imposed on the Debtors.

(g) On or after the Effective Date, Debtor Eiger BioPharmaceuticals, Inc. may convert from a Delaware corporation to a Delaware limited liability company (the “Eiger Conversion”), which shall be deemed effective for all purposes without the necessity for any other or further actions to be taken by or on behalf of the Debtors or the Wind-Down Debtors; provided, however, that the Debtors or the Wind-Down Debtors may, but will not be required to, take appropriate action to document such conversion under applicable law. The Wind-Down Debtors shall be authorized to adopt any agreements, documents, and instruments and to take any other actions contemplated under the Plan as necessary to consummate the Plan without the need for any approvals, authorizations or consents, except those expressly required under the Plan.

On or before the Effective Date, the Debtors or the Plan Administrator shall enter into and take any actions that may be necessary or appropriate to effectuate the Sale Transactions or the Wind-Down of the Debtors, as applicable, including but not limited to: (1) the Eiger Conversion; (2) the execution and delivery of appropriate agreements or other documents of consolidation, conversion, disposition, transfer, or dissolution containing terms that are consistent with the terms of this Plan and that satisfy the requirements of applicable law; (3) the execution and delivery of any appropriate instruments of transfer, assignment, assumption, or delegation of any asset, property, right, liability, debt, duty, or obligation on terms consistent with this Plan; (4) the delivery of Liquidating Trust Assets to the Liquidating Trustee; (5) the filing of appropriate documents with the appropriate governmental authorities pursuant to applicable law; and (6) any and all other actions that the Debtors or the Plan Administrator determine are necessary or appropriate to effectuate the Plan.

1. Wind Down of the Debtors

The responsibilities and authority of the Plan Administrator shall include the following: (a) administering the Professional Fee Reserve Account and the Wind-Down Budget on the terms set forth herein; (b) administering and paying taxes, including, among other things, (i) filing tax returns (to the extent not the obligation of any Purchaser), and (ii) representing the interest and account of the Debtors before any taxing authority in all matters; (c) retaining and paying, without the need for retention or fee applications, professionals in connection with the Plan Administrator’s performance of its duties under this Plan; (d) distributing information statements as required for U.S. federal income tax and other applicable tax purposes; (e) complying with any continuing obligations under the Asset Purchase Agreements, as applicable; (f) Filing an application for entry by the Bankruptcy Court of a final decree closing the Chapter 11 Cases; and (g) making distributions to Professionals for Allowed Professional Compensation Claims from the Professional Fee Reserve Account.

The responsibilities and authority of the Liquidating Trustee shall include the following: (a) preserving and liquidating the Debtors’ assets remaining after consummation of the Sale Transactions, if any, including through the prosecution of any Claims or Retained Causes of Action; (b) considering, litigating, or resolving disputed Claims; (c) distributing the Distributable Cash and other assets of the Debtors’ Estates pursuant to the terms of this Plan to Holders of

Allowed Claims and Interests; (d) procuring the necessary insurance to facilitate the Wind-Down, including appropriate D&O Liability Insurance Policies; and (e) performing such other responsibilities as may be vested in the Liquidating Trustee pursuant to this Plan or an order of the Bankruptcy Court (including, without limitation, the Confirmation Order), or as may be necessary and proper to carry out the provisions of this Plan.

Subject to the provisions of the Plan concerning the Professional Fee Reserve Account and the Wind-Down Budget, the Debtors or the Liquidating Trustee (as applicable) shall fund distributions under the Plan with the Liquidating Trust Assets, including but not limited to, (1) the remaining proceeds from the Sale Transactions, (2) the Debtors’ Cash on hand delivered to the Liquidating Trustee, and (3) the recovery, if any, from prosecution or settlement of the Retained Causes of Action, all in accordance with the terms herein.

On the Effective Date, the attorney-client privilege, the attorney work product doctrine and any similar privilege against disclosure, and all other similar immunities (all together, “Privileges”) belonging to the Debtors or the Estates that concern or in any way relate to (a) any of the Liquidating Trust Assets, or that would apply to communications, documents, or records recorded in magnetic, optical, or other form of electronic medium concerning or in any way relating to any Liquidating Trust Assets, shall vest in the Liquidating Trust, and (b) any of the assets vesting in the Wind-Down Debtors, or that would apply to communications, documents, or records recorded in magnetic, optical, or other form of electronic medium concerning or in any way relating to any such assets, shall vest in the Wind-Down Debtors. The Liquidating Trustee shall have the sole right to waive Privileges that concern or in any way relate to any of the Liquidating Trust Assets or that would apply to communications, documents, or electronic records concerning or in any way relating to any Liquidating Trust Assets. The Plan Administrator shall have the sole right to waive Privileges that concern or in any way relate to any of the assets vesting in the Wind-Down Debtors or that would apply to communications, documents, or electronic records concerning or in any way relating to any such assets.

In accordance with section 1123(b) of the Bankruptcy Code, the Liquidating Trustee or the Plan Administrator, as applicable, shall retain and may enforce all rights to commence and pursue, as appropriate, any and all Causes of Action of the Debtors, including any actions specifically enumerated in the Schedule of Retained Causes of Action, that are not otherwise transferred or sold pursuant to the Sale Transactions or distributed pursuant to the Plan, whether arising before or after the Petition Date, and the Liquidating Trustee’s or the Plan Administrator’s, as applicable, rights to commence, prosecute, or settle such Causes of Action shall be preserved notwithstanding the occurrence of the Effective Date, other than the Causes of Action released by the Debtors pursuant to the releases and exculpations contained in the Plan, including in Article IX hereof, which shall be deemed released and waived by the Debtors as of the Effective Date. No preclusion doctrine, including the doctrines of res judicata, collateral estoppel, issue preclusion, claim preclusion, estoppel (judicial, equitable, or otherwise), or laches, shall apply to such Causes of Action upon, after, or as a consequence of the Confirmation or Consummation. No Entity (other than the Released Parties) may rely on the absence of a specific reference in the Plan, the Plan Supplement, or the Disclosure Statement to any Cause of Action against it as any indication that the Debtors, the Liquidating Trustee, or the Plan Administrator, as applicable, will not pursue any and all available Causes of Action of the Debtors against it.

On the Effective Date, the Debtors shall not be dissolved unless and until the Plan Administrator, in consultation with the Liquidating Trustee, determines that dissolution will not have any adverse impact on the value of the Debtors’ assets; provided that neither the Debtors nor any party released pursuant to Article IX herein shall be responsible for any liabilities that may arise as a result of non-dissolution of the Debtors; provided further, that nothing in the Plan shall be construed as relieving the Debtors or the Plan Administrator (as applicable) of their duties to pay U.S. Trustee Statutory Fees as required by the Bankruptcy Code and applicable law until such time as a final decree is entered in the Debtors’ Chapter 11 Cases or the cases are dismissed or converted to cases under chapter 7 of the Bankruptcy Code. The Plan Administrator shall submit with the appropriate governmental agencies a copy of the Confirmation Order, which Confirmation Order shall suffice for purposes of obtaining a Certificate of Dissolution from the applicable Secretary of State or equivalent body.

Without limiting the foregoing, on the Effective Date and following satisfaction of the Debtors’ distribution and funding requirements set forth in the Plan, the Debtors shall have no further duties or responsibilities in connection with implementation of this Plan, and the directors and officers of the Debtors shall be deemed to have resigned in favor of the ongoing administration of the Debtors’ affairs by the Plan Administrator. From and after the Effective Date, the Plan Administrator and the Liquidating Trustee shall be authorized to act on behalf of the Estates, as applicable, provided that neither of them shall have duties other than as expressly set forth in the Plan or the Confirmation Order.

Except for the purpose of evidencing a right to a distribution under this Plan and except as otherwise set forth in this Plan, on the Effective Date, all agreements, instruments, notes, certificates, indentures, mortgages, securities and other documents evidencing any Claim or Interest, and any rights of any Holder in respect thereof, shall be deemed cancelled and of no further force or effect and the obligations of the Debtors thereunder shall be deemed fully satisfied, released, and discharged and, as applicable, shall be deemed to have been surrendered to the Liquidating Trustee. The Holders of or parties to such cancelled instruments, securities, and other documentation shall have no rights arising from or related to such instruments, securities, or other documentation or the cancellation thereof, except the rights provided for pursuant to this Plan.

Upon entry of the Confirmation Order, the Debtors or the Plan Administrator or the Liquidating Trustee (as applicable) shall be authorized to execute, deliver, file, or record such contracts, instruments, releases, consents, certificates, resolutions, programs, and other agreements or documents, and take such acts and actions as may be reasonable, necessary, or appropriate to effectuate, implement, consummate, and/or further evidence the terms and conditions of this Plan and any transactions described in or contemplated by this Plan.

Notwithstanding anything to the contrary herein, nothing in this Plan shall affect, impair or supersede the Sale Orders or Sale Transactions Documents, each of which remains in full force and effect and governs in the event of any inconsistency with the Plan.

Prior to, on, or after the Effective Date (as appropriate), all matters expressly provided for under this Plan that would otherwise require approval of the stockholders, security holders, officers, directors, or other owners of the Debtors shall be deemed to have occurred and shall be in effect prior to, on, or after the Effective Date (as applicable) pursuant to the applicable law of the state(s) in which the Debtors are formed, without any further vote, consent, approval, authorization, or other action by such stockholders, security holders, officers, directors, or other owners of the Debtor or notice to, order of, or hearing before, the Bankruptcy Court.

Notwithstanding the combination of separate plans of liquidation for the Debtors set forth in this Plan for purposes of economy and efficiency, this Plan constitutes a separate chapter 11 plan for each Debtor. Accordingly, if the Bankruptcy Court does not confirm this Plan with respect to one or more Debtors, it may still confirm this Plan with respect to any other Debtor that satisfies the Confirmation requirements of section 1129 of the Bankruptcy Code.

ARTICLE V.

TREATMENT OF EXECUTORY CONTRACTS AND UNEXPIRED LEASES

On the Effective Date, except as otherwise provided herein (which exclusion includes the Indemnification Obligations and the D&O Liability Insurance Policies) or otherwise identified on the Schedule of Assumed Executory Contracts and Unexpired Leases, if any (which shall be included in the Plan Supplement), all Executory Contracts or Unexpired Leases not previously assumed, assumed and assigned, or rejected pursuant to an order of the Bankruptcy Court, will be deemed rejected, in accordance with the provisions and requirements of sections 365 and 1123 of the Bankruptcy Code other than those Executory Contracts or Unexpired Leases that are the subject of a motion to assume that is pending on the Confirmation Date.

Assumption of any Executory Contract or Unexpired Lease pursuant to the Sale Transactions Documents or this Plan, and payment of any Cures relating thereto, shall, upon satisfaction of the applicable requirements of section 365 of the Bankruptcy Code, result in the full, final, and complete release and satisfaction of any Claims or defaults, whether monetary or nonmonetary, including defaults or provisions restricting the change in control of ownership interest composition or other bankruptcy-related defaults, arising under any assumed Executory Contract or Unexpired Lease at any time prior to the effective date of assumption.

Exhibit A  Page 36 of 58

If the rejection of an Executory Contract or Unexpired Lease pursuant to the Plan and Confirmation Order results in a Claim, then, unless otherwise ordered by the Bankruptcy Court, such Claim shall be forever barred and shall not be enforceable against the Debtors, the Estates, the Plan Administrator, or the Liquidating Trustee, or any of their respective assets and properties unless a Proof of Claim is Filed with the Notice and Claims Agent and served upon counsel to the Plan Administrator and the Liquidating Trustee within thirty (30) days of the Effective Date.

The foregoing applies only to Claims arising from the rejection of an Executory Contract or Unexpired Lease under the Plan and Confirmation Order; any other Claims held by a party to a rejected Executory Contract or Unexpired Lease shall have been evidenced by a Proof of Claim Filed by the applicable Bar Date or shall be barred and unenforceable. Claims arising from the rejection of Executory Contracts or Unexpired Leases under the Plan and Confirmation Order shall be classified as General Unsecured Claims and shall, if Allowed, be treated in accordance with the provisions herein.

Any Claims arising from the rejection of an Executory Contract or Unexpired Lease pursuant to the Plan and Confirmation Order that are not timely Filed within thirty (30) days of the Effective Date will be disallowed automatically, forever barred from assertion, and shall not be enforceable against, as applicable, the Debtors, the Estates, the Plan Administrator, or the Liquidating Trustee, or any of their respective assets and properties.

Neither the exclusion nor the inclusion by the Debtors of any contract or lease on any exhibit, schedule, or other annex to this Plan or in the Plan Supplement, nor anything contained in this Plan, shall constitute an admission by the Debtors that any such contract or lease is or is not an Executory Contract or Unexpired Lease or that the Debtors, the Plan Administrator, or the Liquidating Trustee, or their respective affiliates has any liability thereunder. Except as explicitly provided in this Plan, nothing in this Plan shall waive, excuse, limit, diminish, or otherwise alter any of the defenses, claims, Causes of Action, or other rights of the Debtors, the Plan Administrator, or the Liquidating Trustee under any executory or non-executory contract or unexpired or expired lease. If there is a dispute regarding whether a contract or lease is or was executory or unexpired at the time of its assumption under this Plan, the Debtors, or the Wind-Down Debtors, as applicable, shall have thirty (30) days following entry of a Final Order resolving such dispute to alter their treatment of such contract or lease.

Rejection of any Executory Contract or Unexpired Lease pursuant to the Plan or otherwise shall not constitute a termination of preexisting obligations owed to the Debtors under such Executory Contracts or Unexpired Leases. In particular, notwithstanding any non-bankruptcy law to the contrary, the Debtors expressly reserve and do not waive any right to receive, or any continuing obligation of a counterparty to provide, warranties, indemnity or continued maintenance obligations. The Plan shall constitute a motion to reject all such Executory Contracts or Unexpired Leases that are subject to rejection under this Article V.

Each of the Debtors’ Indemnification Obligations shall not be discharged, impaired, or otherwise affected by the Plan. The Indemnification Obligations shall be deemed Executory Contracts assumed by the Debtors under the Plan. Notwithstanding the foregoing, such Indemnification Obligations shall be subject to typical exclusions for actual fraud, willful misconduct, or gross negligence.

Each D&O Liability Insurance Policy to which the Debtors are a party as of the Effective Date shall be deemed an Executory Contract and shall be automatically assumed or assumed and assigned by the applicable Debtor, effective as of the Effective Date, pursuant to sections 365 and 1123 of the Bankruptcy Code. For the avoidance of doubt, coverage for defense and indemnity under the D&O Liability Insurance Policies shall remain available to all individuals within the definition of “Insured” in the D&O Liability Insurance Policies. In addition, after the Effective Date, all officers, directors, agents, or employees of the Debtors who served in such capacity at any time before the Effective Date shall be entitled to the full benefits of the D&O Liability Insurance Policies (including any “tail” policy) in effect or purchased as of the Effective Date for the full term of such policy regardless of whether such officers, directors, agents, and/or employees remain in such positions after the Effective Date, in each case, to the extent set forth in the D&O Liability Insurance Policies.

Any Employment Agreement not assumed and assigned pursuant to the Sale Transactions Documents as part of the Sale Transactions shall be rejected by the Plan Administrator on the Effective Date of the Plan.

Modifications, amendments, supplements, and restatements to a prepetition Executory Contract and/or Unexpired Lease that have been executed by the Debtors during the Chapter 11 Cases shall not be deemed to alter the prepetition nature of the Executory Contract or Unexpired Lease.

ARTICLE VI.

PROVISIONS GOVERNING DISTRIBUTIONS

As of the close of business on the Distribution Record Date, the various transfer registers for each of the Classes of Claims or Interests as maintained by the Debtors, or their respective agents, shall be deemed closed, and there shall be no further changes in the record Holders of any of the Claims or Interests. The Disbursing Agent shall have no obligation to recognize any ownership transfer of the Claims or Interests occurring on or after the Distribution Record Date. The Disbursing Agent shall be entitled to recognize and deal for all purposes hereunder only with those record Holders stated on the transfer ledgers as of the close of business on the Distribution Record Date, to the extent applicable.

Except as otherwise provided herein, the Disbursing Agent shall make distributions to Holders of Allowed Claims and Allowed Interests as of the Distribution Record Date at the address for each such Holder as indicated on the Debtors’ records as of the date of any such distribution; provided that the manner of such distributions shall be determined at the discretion of the Disbursing Agent; provided, further, that to the extent a Proof of Claim has been filed, the address for each Holder of an Allowed Claim shall be deemed to be the address set forth in any Proof of Claim Filed by that Holder. The Disbursing Agent shall make all distributions for Class 3 Claims to the Prepetition Term Loan Agent, who shall then distribute such individual amounts to the Prepetition Term Loan Secured Parties in accordance with the Prepetition Term Loan Documents.

The Disbursing Agent will implement a procedure to ensure post-petition interest accruing on Class 4 Claims is calculated using the appropriate contractual rate, as applicable, through the date on which a distribution is made on account of the Claim.

Exhibit A  Page 39 of 58

In connection with this Plan, any Person issuing any instrument or making any distribution or payment in connection therewith, shall comply with all applicable withholding and reporting requirements imposed by any federal, state, or local taxing authority. In the case of a non-Cash

distribution that is subject to withholding, the distributing party may require the intended recipient of such distribution to provide the withholding agent with an amount of Cash sufficient to satisfy such withholding tax as a condition to receiving such distribution or withhold an appropriate portion of such distributed property and either (1) sell such withheld property to generate Cash necessary to pay over the withholding tax (or reimburse the distributing party for any advance payment of the withholding tax) or (2) pay the withholding tax using its own funds and retain such withheld property. The distributing party shall have the right not to make a distribution under this Plan until its withholding or reporting obligation is satisfied pursuant to the preceding sentences. Any amounts withheld pursuant to this Plan shall be deemed to have been distributed to and received by the applicable recipient for all purposes of this Plan.

Any party entitled to receive any property as an issuance or distribution under this Plan shall, upon request, deliver to the withholding agent or such other Person designated by the Liquidating Trustee the appropriate IRS Form or other tax forms or documentation requested by the Liquidating Trustee to reduce or eliminate any required federal, state, or local withholding. If the party entitled to receive such property as an issuance or distribution fails to comply with any such request for a one hundred eighty (180) day period beginning on the date after the date such request is made, the amount of such issuance or distribution shall irrevocably revert to the Liquidating Trustee and any Claim in respect of such distribution under this Plan shall be discharged and forever barred from assertion against such Debtor, the Plan Administrator, or the Liquidating Trustee or its respective property.

Notwithstanding the above, each Holder of an Allowed Claim or Interest that is to receive a distribution under this Plan shall have the sole and exclusive responsibility for the satisfaction and payment of any tax obligations imposed on such Holder by any Governmental Unit, including income, withholding, and other tax obligations, on account of such Plan Distribution.

Distributions shall be made on or after the Effective Date to Holders of Allowed Claims or Allowed Interests. In the event that any payment or act under this Plan is required to be made or performed on a date that is not a Business Day, then the making of such payment or the performance of such act may be completed on or as soon as reasonably practicable after the next succeeding Business Day, but shall be deemed to have been completed as of the required date. Except as otherwise provided in the Plan, Holders of Claims shall not be entitled to interest, dividends, or accruals on the distributions provided for in the Plan, regardless of whether such distributions are delivered on or at any time after the Effective Date.

Except as may be otherwise provided in the Sale Orders or Cash Collateral Order, all distributions under this Plan shall be made by the Disbursing Agent on and after the Effective Date and as provided herein. The Disbursing Agent shall not be required to give any bond or surety or other security for the performance of its duties.

As a condition precedent to receiving any distribution under this Plan, each holder of a certificated instrument or note must surrender such instrument or note held by it to the Liquidating Trustee or the Liquidating Trustee’s designee. Any holder of such instrument or note that fails to (1) surrender the instrument or note; or (2) execute and deliver an affidavit of loss or indemnity reasonably satisfactory to the Liquidating Trustee and furnish a bond in form, substance, and amount reasonably satisfactory to the Liquidating Trustee within six (6) months of being entitled to such distribution shall be deemed to have forfeited all rights and claims and may not participate in any distribution hereunder.

Subject to applicable Bankruptcy Rules, all distributions to Holders of Allowed Claims or Allowed Interests shall be made by the Disbursing Agent, who shall transmit such distributions to the applicable Holders of Allowed Claims or Interests or their designees.

If any distribution to a Holder of an Allowed Claim (1) is returned as undeliverable for lack of a current address or otherwise; or (2) is not cashed or otherwise presented for collection by the Holder of the Allowed Claim within ninety (90) calendar days after the mailing of such distribution, the Liquidating Trustee shall be authorized to cancel such distribution check and file with the Bankruptcy Court the name and last known address of the Holder of undeliverable distribution or uncashed distribution, as applicable. If, after the passage of thirty (30) calendar days after such Filing, the payment or distribution on the Allowed Claim still cannot be made, then (1) the Holder of such Claim shall cease to be entitled to the undeliverable distribution or uncashed distribution, which will revert to the Liquidating Trustee for distribution in accordance with the terms of this Plan; and (2) the Allowed Claim of such Holder shall be deemed disallowed and expunged for purposes of further distributions under the Plan.

Except as specifically provided herein, at the option of the Debtors or the Liquidating Trustee, as applicable, any Cash payment to be made under this Plan may be made by a check or wire transfer or as otherwise required or provided in applicable agreements or customary practices of the Debtors.

As of the Effective Date, any Claim asserted in currency other than U.S. dollars shall be automatically deemed converted to the equivalent U.S. dollar value using the exchange rate for the applicable currency as published in The Wall Street Journal on the Petition Date.

The Debtors or the Liquidating Trustee, pursuant to the Bankruptcy Code (including section 553 of the Bankruptcy Code), and applicable bankruptcy and/or non-bankruptcy law, without the approval of the Bankruptcy Court and upon no less than fourteen (14) calendar days’ notice to the applicable Holder of a Claim, or as may be agreed to by the Holder of a Claim, may, but shall not be required to, set off against or recoup against any Allowed Claim and the distributions to be made pursuant to this Plan on account of such Allowed Claim, any claims of any nature whatsoever that the Debtors or their Estates may have against the Holder of such Allowed Claim; provided that neither the failure to effect such a setoff or recoupment nor the allowance of any Claim hereunder shall constitute a waiver or release by the Debtors or the Liquidating Trustee of any such claim the Debtors or their Estates may have against the Holder of such Claim.

No payment of Cash in an amount of less than one hundred U.S. dollars ($100.00) shall be required to be made on account of any Allowed Claim. Such undistributed amount may instead be used in accordance with the Plan and the Wind-Down Budget. If the Cash available for the final distribution is less than the cost to distribute such funds, the Liquidating Trustee may donate such funds to the unaffiliated charity of its choice.

Except as otherwise provided in this Plan or as otherwise required by law, distributions with respect to an Allowed Claim shall be allocated first to the principal portion of such Allowed Claim (as determined for U.S. federal income tax purposes) and, thereafter, to the remaining portion of such Allowed Claim, if any.

Except as otherwise provided in this Plan, any distribution or transfer made under this Plan, including distributions to any Holder of an Allowed Claim, shall be free and clear of any Liens, Claims, encumbrances, charges, and other interests, and no other entity shall have any interest, whether legal, beneficial, or otherwise, in property distributed or transferred pursuant to this Plan.

1.Claims Paid by Third Parties

If a Holder of a Claim receives a payment or other satisfaction of its Claim other than through the Debtors or the Liquidating Trustee on account of such Claim, such Claim shall be reduced by the amount of such payment or satisfaction without an objection to such Claim having to be Filed and without any further notice to or action, order, or approval of the Bankruptcy Court, and if the Claim was paid or satisfied in full other than through the Debtors or the Liquidating Trustee, then such Claim shall be disallowed and any recovery in excess of a single recovery in full shall be paid over to the Liquidating Trustee without an objection to such Claim having to be Filed and without any further notice to or action, order, or approval of the Bankruptcy Court. To the extent a Holder of a Claim receives a distribution on account of such Claim and receives payment or satisfaction from a party that is not the Debtors or the Liquidating Trustee on account of such Claim, such Holder shall, within fourteen (14) calendar days of receipt thereof, repay or return the distribution to the Liquidating Trustee, to the extent the Holder’s total recovery on account of such Claim from the third party and under the Plan exceeds the amount of such Claim as of the date of any such distribution under the Plan.

2. Claims Payable by Third Parties

No distributions under the Plan shall be made on account of an Allowed Claim that is payable pursuant to one of the Debtors’ Insurance Policies until the Holder of such Allowed Claim has exhausted all remedies with respect to such Insurance Policy. To the extent that one or more of the Debtors’ insurers agrees to satisfy in full or in part a Claim (if and to the extent adjudicated by a court of competent jurisdiction), then immediately upon such insurers’ agreement, the applicable portion of such Claim may be expunged without an objection to such Claim having to be Filed and without any further notice to or action, order, or approval of the Bankruptcy Court.

3. Applicability of Insurance Policies

Except as otherwise provided in the Plan, distributions to Holders of Allowed Claims shall be in accordance with the provisions of any applicable insurance policy. Except as set forth in Article IX herein, nothing in this Plan shall constitute or be deemed a waiver of any Cause of Action that the Debtors or any Entity, including the Liquidating Trustee, may hold against any other Entity, including insurers under any policies of insurance, nor shall anything contained herein constitute or be deemed a waiver by such insurers of any defenses, including coverage defenses, held by such insurers.

Unless otherwise specifically provided for in this Plan or the Confirmation Order, or required by applicable bankruptcy and non-bankruptcy law, post-petition interest shall not accrue or be paid on any prepetition Claims, and no Holder of a Claim shall be entitled to interest accruing on or after the Petition Date on such Claim.

ARTICLE VII.

PROCEDURES FOR RESOLVING CONTINGENT,

UNLIQUIDATED, AND DISPUTED CLAIMS

After the Effective Date, the Liquidating Trustee shall have and retain any and all rights and defenses that the Debtors had with respect to any Claim or Interest immediately prior to the Effective Date.

Except as otherwise specifically provided in the Plan, after the Effective Date, the Liquidating Trustee shall have the sole authority to: (1) File, withdraw, or litigate to judgment, objections to Claims or Interests; (2) settle or compromise any Disputed Claim without any further notice to or action, order, or approval by the Bankruptcy Court; and (3) administer and adjust the Claims Register to reflect any such settlements or compromises without any further notice to or action, order, or approval by the Bankruptcy Court.

Before or after the Effective Date, the Debtors or the Liquidating Trustee may (but are not required to) at any time request that the Bankruptcy Court estimate any Disputed Claim that is contingent or unliquidated pursuant to section 502(c) of the Bankruptcy Code for any reason, regardless of whether any party previously has objected to such Claim or whether the Bankruptcy Court has ruled on any such objection, and the Bankruptcy Court shall retain jurisdiction to estimate any such Claim, including during the litigation of any objection to any Claim or during the appeal relating to such objection.

Notwithstanding any provision otherwise herein, a Claim that has been expunged or disallowed from the Claims Register, but that either is subject to appeal or has not been the subject of a Final Order, shall be deemed to be estimated at zero dollars ($0.00) unless otherwise ordered by the Bankruptcy Court. In the event that the Bankruptcy Court estimates any contingent or unliquidated Claim, that estimated amount shall constitute a maximum limitation on such Claim for all purposes under the Plan (including for purposes of distributions), and the Debtors or the Liquidating Trustee (as applicable) may elect to pursue any supplemental proceedings to object to any ultimate distribution on such Claim.

Any Claim that has been paid, satisfied, or assumed by the Purchaser(s) in the Sale Transactions, or any Claim that has been amended or superseded, may be adjusted or expunged on the Claims Register by the Debtors or the Liquidating Trustee (as applicable) without an objection to such Claim having to be Filed and without any further notice to or action, order, or approval of the Bankruptcy Court.

Except as otherwise provided herein, any objections to Claims shall be Filed on or before the Claims Objection Bar Date (as such date may be extended upon presentment of an order to the Bankruptcy Court by the Debtors or the Liquidating Trustee).

Except as otherwise expressly set forth herein, all Claims and Interests of any Entity from which property is sought by the Debtors under sections 542, 543, 550, or 553 of the Bankruptcy Code or that the Debtors, the Liquidating Trustee allege is a transferee of a transfer that is avoidable under sections 522(f), 522(h), 544, 545, 547, 548, 549, or 724(a) of the Bankruptcy Code shall be disallowed if: (1) the Entity, on the one hand, and the Debtors or the Liquidating Trustee, on the other hand, agree or the Bankruptcy Court has determined by Final Order that such Entity or transferee is liable to turn over any property or monies under any of the aforementioned sections of the Bankruptcy Code; and (2) such Entity or transferee has failed to turn over such property by the date set forth in such agreement or Final Order.

Except as provided herein or otherwise agreed to by the Liquidating Trustee, any Holder of a Claim Filed via Proof of Claim after the Bar Date shall not receive any distributions on account of such Claims, unless on or before the Combined Hearing such late Claim has been deemed timely Filed by a Final Order.

All Claims held by Persons or Entities against whom or which the Debtor has commenced a proceeding asserting a Cause of Action under sections 542, 543, 544, 545, 547, 548, 549, or 550 of the Bankruptcy Code or that is a transferee of a transfer avoidable under section 522(f), 522(h), 544, 545, 548, 549 or 724(a) of the Bankruptcy Code shall be deemed Disputed Claims pursuant to section 502(d) of the Bankruptcy Code, and Holders of such Claims shall not be entitled to vote to accept or reject this Plan. A Claim deemed Disputed pursuant to this Article VII.H. shall continue to be Disputed for all purposes until the relevant proceeding against the Holder of such Claim has been settled or resolved by a Final Order and any sums due to the Debtors or the Liquidating Trustee from such Holder have been paid.

Except as provided herein, on or after the Effective Date, without the prior authorization of the Bankruptcy Court, the Plan Administrator, or the Liquidating Trustee, as applicable, a Claim may not be Filed or amended, and any such new or amended Claim Filed shall be deemed disallowed in full and expunged without any further notice to or action, order, or approval of the Bankruptcy Court.

If an objection to a Claim, Proof of Claim, or portion thereof is Filed, no payment or distribution provided under the Plan shall be made on account of such Claim, Proof of Claim, or portion thereof unless and until the Disputed Claim becomes an Allowed Claim.

To the extent that a Disputed Claim ultimately becomes an Allowed Claim, distributions shall be made to the Holder of such Allowed Claim in accordance with the provisions of the Plan. Within ten (10) days after the date that the order or judgment of the Bankruptcy Court allowing any Disputed Claim becomes a Final Order, the Disbursing Agent shall provide to the Holder of such Claim the distribution to which such Holder is entitled under the Plan, unless otherwise provided by order of the Bankruptcy Court. No interest shall accrue or be paid on any Claim with respect to the period from the Effective Date to the date a final distribution is made on account of such Claim unless the Plan provides otherwise.

Notwithstanding anything to the contrary in the foregoing, the releases set forth above do not release any post-Effective Date obligations of any party or Entity under the Plan, the Confirmation Order, or any document, instrument, or agreement (including those set forth in the Plan Supplement) executed to implement the Plan or any Claim or obligation arising under the Plan.

Except as otherwise specifically provided in the Plan, no Exculpated Party shall have or incur, and each Exculpated Party is hereby exculpated from any Cause of Action for any claim related to any act or omission taking place between the Petition Date and the Effective Date in connection with, relating to, or arising out of, the Chapter 11 Cases, the Disclosure Statement, the Plan, the Sale Transactions, or any aspect of the Liquidation Transaction, including any contract, instrument, release or other agreement or document (including providing any legal opinion requested by any Entity regarding any transaction, contract, instrument, document, or other agreement contemplated by the Plan or the reliance by any Exculpated Party on the Plan or the Confirmation Order in lieu of such legal opinion) created or entered into in connection with the Disclosure Statement or the Plan, the Sale Transactions, the filing of the Chapter 11 Cases, the pursuit of Confirmation, the administration and implementation of the Plan, or the distribution of property under the Plan or any other related agreement, except for claims related to any act or omission that is determined in a Final Order of a court of competent jurisdiction to have constituted actual fraud, willful misconduct, or gross negligence but in all respects such Entities shall be entitled to reasonably rely upon the advice of counsel with respect to their duties and responsibilities pursuant to the Plan.

Except as otherwise provided in the Plan or the Confirmation Order, all Entities who have held, hold, or may hold Claims, Interests, Causes of Action, or liabilities that: (1) are subject to compromise and settlement pursuant to the terms of the Plan; (2) have been released pursuant to the Plan; (3) were purchased and released by a Purchaser in connection with the Sale Transactions; (4) are subject to exculpation pursuant to the Plan; or (5) are otherwise discharged, satisfied, stayed, released, or terminated pursuant to the terms of the Plan, are permanently enjoined and precluded, from and after the Effective Date, from commencing or continuing in any manner, any action or other proceeding, including on account of any Claims, Interests, Causes of Action, or liabilities that have been compromised or settled against any of the Debtors or any Entity so released or exculpated (or the property or estate of any Entity, directly or indirectly, so released or exculpated) on account of, or in connection with or with respect to, any discharged, released, settled, compromised, or exculpated Claims, Interests, Causes of Action, or liabilities, including being permanently enjoined and precluded, from and after the Effective Date, from taking any of the following actions against, as applicable, the Debtors, the Plan Administrator, the Liquidating Trustee, the Released Parties, or Exculpated Parties (as applicable): (1) commencing or continuing in any manner any action or other proceeding of any kind on account of or in connection with or with respect to any such Claims or Interests; (2) enforcing, attaching, collecting, or recovering by any manner or means any judgment, award, decree, or order against such Entities on account of or in connection with or with respect to any such Claims or Interests; (3) creating, perfecting, or enforcing any lien or encumbrance of any kind against such Entities or the property or the estate of such Entities on account of or in connection with or

For the avoidance of doubt, nothing in the foregoing paragraph will act as a discharge injunction.

Upon the Bankruptcy Court’s entry of the Confirmation Order, all Holders of Claims and Interests and other parties in interest, along with their respective present or former employees, agents, officers, directors, or principals, shall be enjoined from taking any actions to interfere with the implementation or consummation of this Plan by the Debtors, the Plan Administrator, the Liquidating Trustee, and their respective affiliates, employees, advisors, officers and directors, or agents.

Because the Debtors are liquidating and will not engage in business after consummation of the Plan, they are not entitled to a discharge of obligations pursuant to section 1141 of the Bankruptcy Code with regard to any Holders of Claims or Interests.

Except as otherwise provided herein or in any contract, instrument, release, or other agreement or document created pursuant to the Plan, on the Effective Date and concurrently with the applicable distributions made pursuant to the Plan and, in the case of a Secured Claim, satisfaction in full of the portion of the Secured Claim that is Allowed as of the Effective Date in accordance with the terms of the Plan, all mortgages, deeds of trust, Liens, pledges, or other security interests against any property of the Estate shall be fully released and discharged, and all of the right, title, and interest of any holder of such mortgages, deeds of trust, Liens, pledges, or other security interests shall revert to the Debtors and their successors and assigns.

If any Holder of an Other Secured Claim or any agent for such Holder has filed or recorded publicly any Liens and/or security interests to secure such Holder’s Other Secured Claim, as soon as practicable on or after the date such Holder has been satisfied in full pursuant to the Plan, such Holder (or the agent for such Holder) shall take any and all steps requested by the Liquidating Trustee that are necessary or desirable to record or effectuate the cancellation and/or extinguishment of such Liens and/or security interests, including the making of any applicable filings or recordings, and the Liquidating Trustee shall be entitled to make any such filings or recordings on such Holder’s behalf. The presentation or filing of the Confirmation Order to or with any federal, state, provincial, or local agency or department shall constitute good and sufficient evidence of, but shall not be required to effect, the termination of such Liens.

For the avoidance of doubt, any party that obtains such determination and authorization and subsequently wishes to amend the authorized complaint or petition to add any Causes of Action not explicitly included in the authorized complaint or petition must obtain authorization from the Bankruptcy Court before filing any such amendment in the court where such complaint or petition is pending.

MISCELLANEOUS PROVISIONS

Notwithstanding Bankruptcy Rules 3020(e), 6004(h), 7062, or otherwise, upon the occurrence of the Effective Date, the terms of this Plan shall be immediately effective and enforceable and deemed binding upon and inure to the benefit of the Debtors or the Plan Administrator, the Liquidating Trustee, the Holders of Claims or Interests, the Released Parties, and each of their respective successors and assigns. Any action to be taken on the Effective Date may be taken on or as soon as reasonably practicable thereafter.

On or before the Effective Date, the Debtors may File with the Bankruptcy Court such agreements and other documents as may be necessary or appropriate to effectuate and further evidence the terms and conditions of the Plan. The Debtors or the Liquidating Trustee (as applicable) and all Holders of Claims or Interests receiving distributions pursuant to the Plan and all other parties in interest shall, from time to time, prepare, execute, and deliver any agreements or documents and take any other actions as may reasonably be necessary or advisable to effectuate the provisions and intent of the Plan or the Confirmation Order.

On the Effective Date, this Plan shall be deemed to be substantially consummated (within the meaning set forth in section 1101 of the Bankruptcy Code) pursuant to section 1127(b) of the Bankruptcy Code.

The Plan shall have no force or effect unless and until the Bankruptcy Court enters the Confirmation Order. None of the Filing of the Plan, any statement or provision contained in the Plan, or the taking of any action by the Debtors with respect to the Plan, the Disclosure Statement, or the Plan Supplement shall be or shall be deemed to be an admission or waiver of any rights of the Debtors with respect to the Holders of Claims or Interests prior to the Effective Date.

The rights, benefits, and obligations of any Entity named or referred to in the Plan shall be binding on, and shall inure to the benefit of any heir, executor, administrator, successor or assign, beneficiaries or guardian, if any, of each Entity.

The Debtors or the Plan Administrator shall have the right to request an expedited determination of any tax liability pursuant to section 505 of the Bankruptcy Code, including on any unpaid liability of the Debtors’ Estates for any tax incurred during the administration of these Chapter 11 Cases.

Except as otherwise provided in this Plan, to the maximum extent permitted by applicable law and subject to the Bankruptcy Court’s post-confirmation jurisdiction to modify the injunctions and stays under this Plan (1) all injunctions with respect to or stays against an action against property of the Debtors or the Debtors’ Estates arising under or entered during the Chapter 11 Cases under sections 105 or 362 of the Bankruptcy Code, and in existence on the date the Confirmation Order is entered, shall remain in full force and effect until such property is no longer

property of the Debtors or the Debtors’ Estates; and (2) all other injunctions and stays arising under or entered during the Chapter 11 Cases under sections 105 or 362 of the Bankruptcy Code shall remain in full force and effect until the earliest of (a) the date that the Chapter 11 Cases are closed pursuant to a final order of the Bankruptcy Court, or (b) the date that the Chapter 11 Cases are dismissed pursuant to a final order of the Bankruptcy Court. All injunctions or stays contained in the Plan or the Confirmation Order shall remain in full force and effect indefinitely.

On the Effective Date, the Plan and the Plan Supplement supersede all previous and contemporaneous negotiations, promises, covenants, agreements, understandings, and representations on such subjects, all of which have become merged and integrated into the Plan.

All exhibits and documents included in the Plan Supplement are incorporated into and are a part of the Plan as if set forth in full in the Plan. Copies of such exhibits and documents shall be made available upon written request to the Debtors’ counsel or the Liquidating Trustee’s counsel (as applicable) at the address above or by downloading such exhibits and documents free of charge from the Notice and Claims Agent’s website at https://veritaglobal.net/eiger. All documents in the Plan Supplement are considered an integral part of the Plan and shall be deemed approved by the Bankruptcy Court pursuant to the Confirmation Order.

Unless a rule of law or procedure is supplied by federal law (including the Bankruptcy Code and Bankruptcy Rules) or unless otherwise specifically stated, the laws of the State of Texas, without giving effect to the principles of conflict of laws, shall govern the rights, obligations, construction, and implementation of the Plan, any agreements, documents, instruments, or contracts executed or entered into in connection with the Plan (except as otherwise set forth in those agreements, in which case the governing law of such agreement shall control), and corporate governance matters.

If any term or provision of the Plan is held by the Bankruptcy Court to be invalid, void, or unenforceable, the Bankruptcy Court shall have the power to alter and interpret such term or provision to make it valid or enforceable to the maximum extent practicable, consistent with the original purpose of the term or provision held to be invalid, void, or unenforceable, and such term or provision shall then be applicable as altered or interpreted. Notwithstanding any such holding, alteration, or interpretation, the remainder of the terms and provisions of the Plan will remain in full force and effect and will in no way be affected, impaired, or invalidated by such holding, alteration, or interpretation.

The Confirmation Order shall constitute a judicial determination and shall provide that each term and provision of the Plan, as it may have been altered or interpreted in accordance with the foregoing, is the following: (1) valid and enforceable pursuant to its terms; (2) integral to the Plan and may not be deleted or modified without the consent of the Debtors or the Liquidating Trustee (as applicable); and (3) nonseverable and mutually dependent.

Upon entry of the Confirmation Order, the Debtors will be deemed to have solicited votes on the Plan in good faith and in compliance with the Bankruptcy Code, and pursuant to section 1125(e) of the Bankruptcy Code, the Debtors and each of their respective Affiliates, agents, representatives, members, principals, shareholders, officers, directors, managers, employees, advisors, and attorneys will be deemed to have participated in good faith and in compliance with the Bankruptcy Code, and, therefore, neither any of such parties or individuals will have any liability for the violation of any applicable law, rule, or regulation governing the solicitation of votes on the Plan.
