The following constitutes Amendment No. 3 to the Schedule 13D filed by the undersigned ("Amendment No. 3"). This Amendment No. 3 amends the Schedule 13D as specifically set forth herein.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

Elliott Working Capital	The aggregate purchase price of the shares of Common Stock directly owned by Elliott is approximately $20,983,040.^.

Elliott International Working Capital	The aggregate purchase price of the shares of Common Stock directly owned by Elliott International is approximately $44,588,794.^.

The Reporting Persons may effect purchases of shares of Common Stock through margin accounts maintained for them with prime brokers, which extend margin credit as and when required to open or carry positions in their margin accounts, subject to applicable federal margin regulations, stock exchange rules and such firms' credit policies. Positions in shares of Common Stock may be held in margin accounts and may be pledged as collateral security for the repayment of debit balances in such accounts. Since other securities may be held in such margin accounts, it may not be possible to determine the amounts, if any, of margin used to purchase shares of Common Stock.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On August 28, 2017, the Reporting Persons entered into a Stockholder Voting and Support Agreement with Optum (the "Support Agreement") in favor of the transaction. Pursuant to the terms of the Support Agreement, the Reporting Persons agreed, among other things, to vote any shares of Common Stock they beneficially own (the "Subject Shares"), at the applicable time, (i) in favor of the merger of Apollo Merger Sub, Inc., a wholly owned subsidiary of Optum, with and into the Issuer (the "Merger"), at any meeting of shareholders called for such purpose and other actions required in furtherance of the foregoing and (ii) against any proposal or action that would constitute a breach of the Merger Agreement, any alternative Company Takeover Proposal (as defined in the Merger Agreement) and any alternative transaction. The Support Agreement does not restrict the Reporting Persons from acquiring additional shares of Common Stock or disposing of any or all shares of Common Stock they beneficially own. Solely in the event of the failure by the Reporting Persons to vote their shares of Common Stock in such a manner, the Reporting Persons have granted to the Issuer and Optum an irrevocable proxy (the "Irrevocable Proxy") to vote the Reporting Persons' shares of Common Stock in favor of the Merger at any meeting of shareholders called for such purpose. The Irrevocable Proxy automatically terminates upon termination of the Support Agreement. The Reporting Persons have agreed that until the termination of the Support Agreement, they shall not deposit, or permit the deposit of, any of the Subject Shares in a voting trust, grant any proxy or power of attorney in respect of the Subject Shares, or enter into any voting agreement or similar arrangement, commitment or understanding with respect to the Subject Shares in violation of the Support Agreement. The Support Agreement will expire upon the earliest of (i) the closing of the Merger, (ii) the termination of the Merger Agreement, (iii) the date of any amendment, modification or supplement to the Merger Agreement that (x) materially and adversely affects the economic interest of the stockholders of the Issuer or (y) otherwise decreases the consideration or changes the form of consideration payable to the stockholders of the Issuer and (iv) March 28, 2018.

The foregoing description of the Support Agreement is qualified in its entirety by reference to the Support Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

Item 5.

Interest in Securities of the Issuer.

Item 5(a) is hereby amended and restated to read as follows:

(a) As of the close of business on August 30, 2017, Elliott, Elliott International and EICA collectively have combined economic exposure in the Issuer of approximately 4.0% of the shares of Common Stock outstanding.

The aggregate percentage of Common Stock reported owned by each person named herein is based upon 40,685,446 shares of Common Stock outstanding as of August 1, 2017, which is the total number of shares of Common Stock outstanding as reported in the Issuer's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 9, 2017.

As of the close of business on August 30, 2017, Elliott beneficially owned 521,898 shares of Common Stock, constituting 1.3% of the shares of Common Stock outstanding.

As of the close of business on August 30, 2017, Elliott International beneficially owned 1,109,029 shares of Common Stock, constituting approximately 2.7% of the shares of Common Stock outstanding. EICA, as the investment manager of Elliott International may be deemed to beneficially own the 1,109,029 shares of Common Stock beneficially owned by Elliott International, constituting approximately 2.7% of the shares of Common Stock outstanding.

Collectively, Elliott, Elliott International and EICA beneficially own 1,630,927 shares of Common Stock, constituting approximately 4.0% of the shares of Common Stock outstanding.

Item 5(c) is hereby amended and restated to read as follows:

(c) The transactions effected by the Reporting Persons during the past 60 days are set forth on Schedule 1 attached hereto.

Item 5(e) is hereby amended and restated to read as follows:

(e) Effective August 29, 2017, the Reporting Persons ceased to be the beneficial owners of more than more than 5% of the shares of Common Stock outstanding.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 is hereby amended and restated to read as follows:

On January 12, 2017 Elliott, Elliott International and EICA entered into a Joint Filing Agreement (the "Joint Filing Agreement") in which the parties agreed to the joint filing on behalf of each of them of statements on Schedule 13D with respect to the securities of the Issuer to the extent required by applicable law. The Joint Filing Agreement is attached as an exhibit to the initial Schedule 13D and is incorporated herein by reference.

On March 1, 2017, an affiliate of the Reporting Persons entered into the Standstill Agreement defined and described in Item 4 of Amendment No. 2 to this Schedule 13D.

On August 28, 2017, the Reporting Persons entered into a Support Agreement with the Issuer defined and described in Item 4 above.

Except as described above in this Item 6, none of the Reporting Persons has any contracts, arrangements, understandings or relationships with respect to the securities of the Issuer.

WHEREAS, as an inducement to Parent's willingness to enter into the Merger Agreement, the Stockholders have agreed to enter into this Agreement and vote their Subject Shares as described herein.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Certain Definitions. Capitalized terms used but not defined herein shall have the respective meanings ascribed to them in the Merger Agreement. For all purposes of and under this Agreement, the following terms shall have the following respective meanings:

(d) the execution and delivery of this Agreement by the Stockholder does not, and the performance of this Agreement by the Stockholder will not, result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation, modification or acceleration) (whether after the giving of notice of or the passage of time or both) under any Law applicable to the Stockholder or the Subject Shares or any contract to which the Stockholder is a party or which is binding on the Stockholder or the Stockholder's Subject Shares, and will not result in the creation of any Lien on any of the Stockholder's Subject Shares;

(e) this Agreement has been duly executed by the Stockholder and constitutes the valid and legally binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, except that (i) such enforceability may be subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar Laws, now or hereafter in effect, affecting creditors' rights and remedies generally and (ii) the remedies of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any Claim therefor may be brought;

(g) the Stockholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon the Stockholder's execution and delivery of this Agreement and the representations, warranties and covenants of the Stockholder contained herein.

8. Appraisal Rights. Each Stockholder (i) irrevocably waives and agrees not to exercise any rights (including under Section 262 of the DGCL) to demand appraisal of any of the Subject Shares or rights to dissent from the Merger that the Stockholder may otherwise have and (ii) agrees not to commence or participate in, and will take all actions necessary to opt out of, any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Sub, the Company or any of their respective successors or Affiliates relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger, including any claim (x) challenging the validity of, seeking to enjoin the operation of, any provision of this Agreement or the Education Purchase Agreement or (y) alleging a breach of any fiduciary duty of the Company Board in connection with the Merger Agreement, the Education Purchase or the transactions contemplated thereby; provided, that the foregoing covenants shall not be deemed a consent to or waiver of any rights of the Stockholder for any breach of this Agreement by Parent or its Affiliates.

11. Miscellaneous.

(a) Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

(b) Waiver. Except as provided in this Agreement, no action taken pursuant to this Agreement, including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of any other party's obligations to comply with its representations, warranties, covenants and agreements contained in this Agreement. The waiver by any party hereto of a breach of any provision hereunder (or any delay in asserting any such breach) shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder or in any other context.

(c) Severability. If any provision of this Agreement, or the application thereof to any Person or circumstance, is to be held invalid or unenforceable, the remainder of this Agreement, and the application of such provision to other Persons or circumstances, shall not be affected thereby, and to such end, the provisions of this Agreement are agreed to be severable.

(d) Assignment. Except as expressly permitted by the terms hereof, no party may assign this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of each other party hereto, and any attempted assignment without such prior written approval shall be void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

(e) Amendments. This Agreement may not be modified, amended, altered or supplemented, except upon the execution and delivery of a written agreement executed by each of the parties hereto.

(f) Specific Performance; Injunctive Relief. The parties agree that irreparable damage for which monetary damages would not be an adequate remedy would occur in the event that any party fails to perform of its obligations under this Agreement, and that the non-breaching party shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which the non-breaching party is entitled at law or in equity. Any party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief to enforce the covenants and obligations contained herein on the basis that the non-breaching party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity and the non-breaching party shall not be required to post a bond or other security in connection with any such order or injunction.

(g) Governing Law. This Agreement and all Claims (whether based on contract, tort or otherwise) arising out of or relating to this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

(h) Jurisdiction and Venue. In addition, each of the parties hereto (i) expressly and irrevocably consents to submit itself to the personal jurisdiction of the Court of Chancery of the State of Delaware, or if that court lacks subject matter jurisdiction, any state or federal court located within the State of Delaware for the purpose of any suit, action or proceeding (whether, in contract, tort, equity or otherwise) relating to this Agreement or any of the transactions contemplated by this Agreement, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, and (iii) agrees that it will not bring any suit, action or proceeding relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts.

(i) Waiver Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER CLAIM ARISING OUT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 11(i).

(j) No Agreement Until Transaction Documents Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute, or be deemed to evidence, a contract, agreement, arrangement or understanding between the parties hereto unless (i) the Merger Agreement is executed and delivered by all parties thereto and (ii) this Agreement is executed and delivered by all parties hereto.

(k) No Third Party Beneficiaries. This Agreement is not intended, and shall not be deemed, to confer any rights, remedies, obligations or liabilities upon any Person other than the parties hereto and their respective heirs, successors, executors, administrators and permitted assigns, to create any agreement of employment with any Person or to otherwise create any third-party beneficiary hereto.
