 Exhibit 10.1 

FORM OF INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is made as of
                    , 2010, by and between Alexion Pharmaceuticals, Inc., a Delaware corporation (the “Company”) and
             (“Indemnitee”). 
 RECITALS

 WHEREAS, although the Certificate of Incorporation of the Company provides for indemnification of the officers and
directors of the Company and Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”), the DGCL expressly contemplates that contracts may be entered into between
the Company and its directors and officers with respect to indemnification of such directors and officers; 
 WHEREAS,
Indemnitee’s continued service to the Company substantially benefits the Company; 
 WHEREAS, the Board of Directors of the
Company (the “Board”) has determined that it is in the best interest of the Company and that it is reasonably prudent and necessary for the Company to contractually obligate itself to indemnify, and, subject to the terms and
conditions of this Agreement, to advance expenses on behalf of, Indemnitee to the fullest extent permitted by applicable law in order to induce Indemnitee to serve or continue to serve the Company free from undue concern that Indemnitee will not be
so indemnified or that any indemnification obligation will not be met; 
 WHEREAS, this Agreement is separate from and in
addition to (a) the Certificate of Incorporation and Bylaws of the Company and (b) the certificate of incorporation, bylaws, partnership agreement or other organizational document, as the case may be, of any Enterprise (as defined below),
and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and 

WHEREAS, Indemnitee does not regard the protection available under the Company’s Certificate of Incorporation and insurance or any
other Enterprise’s certificate of incorporation, bylaws, partnership agreement or other organizational document, as the case may be, and insurance, as adequate in the present circumstances, and may not be willing to serve as a director or
officer without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company and certain other Enterprises on
the condition that Indemnitee be so indemnified. 
 NOW, THEREFORE, in consideration of the promises and the covenants contained
herein, the Company and Indemnitee do hereby covenant and agree as follows: 

 AGREEMENT 

1. Services to the Company and Certain Other Enterprises. Indemnitee will serve or continue to serve as a director and/or officer
of the Company or other Enterprises for so long as Indemnitee is duly elected or appointed or until Indemnitee tenders a resignation or otherwise no longer serves as a director or officer of the Company for any reason. 

2. Definitions. As used in this Agreement: 

(a) “Change of Control” means the occurrence of any of the following events: 

(1) any Person (as defined in Sections 13(d) and 14(d) of the Exchange Act), other than the Company, its affiliates (as defined in Rule

combined voting power of the then outstanding securities entitled to vote generally in the election of directors of the Company (“Voting Securities”) of the Company, or 

(2) individuals who constitute the Board (the “Incumbent Directors”) as of the beginning of any twenty-four month
period (not including any period prior to the date of this Agreement), cease for any reason to constitute at least a majority of the directors of the Company. Notwithstanding the foregoing, any individual becoming a Director subsequent to the
beginning of such period, whose election or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the Directors then comprising the Incumbent Directors, shall be considered an Incumbent Director;
or 
 (3) consummation by the Company of a recapitalization, reorganization, merger, consolidation or other similar transaction
(a “Business Combination”), with respect to which all or substantially all of the individuals and entities who were the beneficial owners of the Voting Securities immediately prior to such Business Combination (the
“Incumbent Shareholders”) do not, following consummation of all transactions intended to constitute part of such Business Combination, beneficially own, directly or indirectly, 50% or more of the Voting Securities of the
corporation, business trust or other entity resulting from or being the surviving entity in such Business Combination (the “Surviving Entity”), in substantially the same proportion as their ownership of such Voting Securities
immediately prior to such Business Combination; or 
 (4) Consummation of a complete liquidation or dissolution of the Company,
or the sale or other disposition of all or substantially all of the assets of the Company, other than to a corporation, business trust or other entity with respect to which, following consummation of all transactions intended to constitute part of
such sale or disposition, more 
  

 -2- 

 
than 50% of the combined Voting Securities is then owned beneficially, directly or indirectly, by the Incumbent Shareholders in substantially the same proportion as their ownership of the Voting
Securities immediately prior to such sale or disposition. 
 (b) “Corporate Status” describes the status of a
person who is or was a director, trustee, general partner, managing member, officer, incorporator, employee, agent or fiduciary of the Company or of any other Enterprise.

of which indemnification is sought by Indemnitee. 
 (d) “Enterprise” means (i) the Company, (ii) any
other corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise which is an affiliate or wholly or partially owned subsidiary of the Company and of which Indemnitee is or was serving as a
director, trustee, general partner, managing member, officer, incorporator, employee, agent or fiduciary and (iii) any other corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise of
which Indemnitee is or was serving at the request of the Company.

incurred in connection with any appeal resulting from any Proceeding, including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent. Expenses, however,
shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee. 
 (g)
“Independent Counsel” means, at any time, any law firm, or a member of a law firm, that (i) is experienced in matters of corporation law and (ii) is not, at such time, or has not been in the five years prior to such time,
retained to represent: (1) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnities under similar indemnification agreements),
or (2) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of
professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. 

(h) “Proceeding” means any threatened, pending or completed action, suit, arbitration, mediation, alternate dispute
resolution mechanism, investigation, inquiry, 
  

 -3- 

 
administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether of a civil, criminal, administrative or
investigative nature, including without limitation any such proceeding pending as of the date of this Agreement, in which Indemnitee was, is or will be involved as a party or otherwise by reason of the fact that Indemnitee is or was an officer or
director of the Company, by reason of any action taken by Indemnitee or of any action on Indemnitee’s part while acting as director or officer of the Company, or by reason of the fact that Indemnitee is or was serving as a director, trustee,
general partner, managing member, officer, incorporator, employee, agent or fiduciary of any other Enterprise, in each case whether or not serving in such capacity at the time any Expense, judgment, fine or amount paid in settlement is incurred for
which indemnification, reimbursement, or advancement of Expenses can be provided under this Agreement. 
 3. Indemnity in
Third-Party Proceedings. The Company shall be liable to indemnify Indemnitee in accordance with the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant (as a witness or otherwise)
in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee shall be indemnified against all Expenses, judgments, fines and amounts paid in settlement
actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not
opposed to the best interests of the Company and, in the case of a criminal Proceeding, had no reasonable cause to believe that Indemnitee’s conduct was unlawful. 

4. Indemnity in Proceedings by or in the Right of the Company. The Company shall be liable to indemnify Indemnitee in accordance
with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant (as a witness or otherwise) in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to
this Section 4, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding (or any claim, issue or matter therein) if Indemnitee acted in
good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however that no indemnification for Expenses shall be made under this Section 4 in respect of any claim, issue or
matter as to which Indemnitee shall have been finally adjudged by a court of competent jurisdiction to be liable to the Company, unless and only to the extent that any court in which the Proceeding was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 

5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of this
Agreement, to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding, the Company shall be liable to indemnify Indemnitee against all Expenses actually and reasonably incurred
by him in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall be liable to
indemnify 
  

 -4- 

 
Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of
this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

6. Indemnification For Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee
is, by reason of Indemnitee’s Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, the Company shall be liable to indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on
Indemnitee’s behalf in connection therewith. 
 7. Additional Indemnification 

(a) Notwithstanding any limitation in Sections 3, 4, or 5, the Company shall be liable to indemnify Indemnitee to the fullest extent
permitted by law if Indemnitee is a party to, or threatened to be made a party to, any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines and amounts paid
in settlement actually and reasonably incurred by Indemnitee in connection with the Proceeding; provided, however, that no indemnity shall be made under this Section 7(a) on account of Indemnitee’s conduct which has been
adjudicated to constitute a breach of Indemnitee’s duty of loyalty to the Company or its shareholders or to constitute an act or omission not in good faith or involving intentional misconduct or a knowing violation of the law. 

(b) For purposes of Section 7(a), the meaning of the phrase “to the fullest extent permitted by law” shall include, but
not be limited to: 
 (1) to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 

(2) to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this
Agreement that increase the extent to which a corporation may indemnify its officers or directors. 
 8. Exclusions.
Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnity payment or advancement of Expenses in connection with any claim made against Indemnitee: 

(a) for which payment has actually been received by or on behalf of Indemnitee under any insurance policy, other indemnity provision or
indemnification arrangement with another Enterprise, except with respect to any excess beyond the amount actually received under any insurance policy, other indemnity provision or indemnification arrangement; 

 

 -5- 

 (b) for an accounting of profits made from the purchase and sale (or sale and purchase) by
Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common law; provided, however, that notwithstanding any limitation on the
Company’s obligation to provide indemnification set forth in this Section 8(b) or elsewhere, Indemnitee shall be entitled to receive advancement of Expenses hereunder with respect to any such claim unless and until a court having
jurisdiction over the claim shall have made a final judicial determination (as to which all rights of appeal therefrom have been exhausted or lapsed) that Indemnitee has violated said statute; or 

(c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of
any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) such indemnification is expressly required to be made by applicable law, (ii) the Proceeding was authorized
by the Board, (iii) such indemnification is provided by the Company, in its sole discretion, pursuant to the powers vested in the Company under the DGCL, or (iv) such indemnification is required to be made pursuant to Section 13.

 9. Advancement of Expenses; Defense of Claim. Subject to the other terms and conditions of this Agreement, the Company
shall be obligated to advance any and all Expenses incurred by Indemnitee in connection with any Proceeding within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances from time to time,
whether prior to or after final disposition of any Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of
Indemnitee to repay any Expenses advanced to the extent and only to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. Any advances (i) shall be unsecured and interest free;
(ii) shall be made without regard to Indemnitee’s ability to repay the advances and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement; and (iii) shall include any
and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. 

10. Procedure for Notification and Requests for Advancement and Indemnification. 

(a) Notification. To obtain advancement of Expenses and/or indemnification under this Agreement, Indemnitee shall, not later than
sixty (60) days after receipt by Indemnitee of notice of the commencement of any Proceeding, except for Proceedings pending as of the date of this Agreement, submit to the Company written notification of the Proceeding; with regard to
Proceedings pending as of the date of this Agreement, Indemnitee shall submit to the Company written notification not later than thirty (30) days after the date of this Agreement. The omission to notify the Company will relieve the Company of
its advancement or indemnification obligations under this Agreement only to the extent the Company can establish that such omission to notify resulted in actual prejudice to it, and the omission to notify the Company will, in any event, not relieve
the Company from any liability which it may have to indemnify Indemnitee otherwise than under this Agreement. The Secretary of the Company shall, promptly 

 

 -6- 

 
upon receipt of notification from Indemnitee pursuant to this Section 10(a), advise the Board in writing that Indemnitee has provided such notification. The Company will be entitled to
participate reasonably in the Proceeding at its own expense. 
 (b) Expense Request. Subject to Section 9, to obtain
advancement of Expenses under this Agreement, Indemnitee shall submit to the Company a written request therefor, together with such invoices or other supporting information as may be reasonably requested by the Company and reasonably available to
Indemnitee, and, only to the extent required by applicable law which cannot be waived, an unsecured written undertaking to repay amounts advanced to the extent that it is ultimately determined that the Indemnitee is not entitled to be indemnified by
the Company. The Company shall make advance payment of Expenses to Indemnitee no later than thirty (30) days after receipt of the written request for advancement (and each subsequent request for advancement) by Indemnitee. If, at the time of
receipt of any such written request for advancement of Expenses, the Company has director and officer insurance policies in effect, the Company will promptly notify the relevant insurers in accordance with the procedures and requirements of such
policies. The Company shall thereafter keep such director and officer insurers informed of the status of the Proceeding or other claim, as appropriate to secure coverage of Indemnitee for such claim in accordance with the terms of such insurance
coverage. 
 (c) Indemnification Request. In order to obtain indemnification under this Agreement, Indemnitee shall,
anytime at Indemnitee’s discretion following notification by Indemnitee of the commencement of any Proceeding pursuant to Section 10(a) of this Agreement and consistent with the time period for the duration of this Agreement as set forth
in Section 15 of this Agreement, submit to the Company a written request for indemnification pursuant to this Section 10(c), including therein or therewith such documentation and information as is reasonably available to Indemnitee and is
reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. No determination of Indemnitee’s entitlement to indemnification shall be made until such written request for a determination is submitted by
Indemnitee to the Company pursuant to this Section 10(c). The failure to submit a written request to the Company will relieve the Company of its indemnification obligations under this Agreement only to the extent the Company can establish that
such failure to make a written request resulted in actual prejudice to it, and the failure to make a written request will not relieve the Company from any liability which it may have to indemnify Indemnitee otherwise than under this Agreement. The
Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Upon submission of a written request for indemnification by Indemnitee pursuant
to this Section 10(c), Indemnitee’s entitlement to indemnification shall be determined according to Section 11 of this Agreement. 

11. Procedure Upon Application for Indemnification. 

(a) Upon receipt of Indemnitee’s written request for indemnification pursuant to Section 10(c), a determination with respect
thereto shall be made in the specific case by one of the following three methods, which shall be at the election of the Board: (i) by a majority vote of 

 

 -7- 

 
the Disinterested Directors, even though less than a quorum, (ii) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less
than a quorum, or (iii) if there are no Disinterested Directors or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee. Notwithstanding the above,
if a determination with respect to Indemnitee’s right to indemnification is to be made following a Change of Control, such determination shall be made in the specific case by Independent Counsel in a written opinion to the Board, a copy of
which shall be delivered to Indemnitee. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within thirty (30) days after such determination. Indemnitee shall reasonably cooperate with the
person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so
cooperating with the Disinterested Directors or Independent Counsel, as the case may be, making such determination shall be advanced and borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification)
and the Company is liable to indemnify and hold Indemnitee harmless therefrom. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above. 

(b) In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 11(a)
hereof, the Independent Counsel shall be selected as provided in this Section 11(b). The Independent Counsel shall be selected by the Board and the Board shall provide written notice to the Indemnitee of the identity of the Independent Counsel
so selected. Such counsel selected by the Board shall certify to Indemnitee in writing that it meets the definition of “Independent Counsel” provided herein. Indemnitee may, within ten (10) days after such written notice of selection
shall have been received, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements
of “Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as
Independent Counsel. If a written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court of competent jurisdiction has determined that
such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to Section 10(c) hereof, no Independent Counsel shall have been selected and not objected to,
either the Company or Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as
Independent Counsel of a person selected by the Court or by such other person as the Court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under
Section 11(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 13(a) of this Agreement, Independent Counsel shall be discharged and 

 

 -8- 

 
relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). The Company shall pay all reasonable fees and expenses
incident to the procedures of this Section 11(b), regardless of the manner in which such Independent Counsel was selected or appointed. 

12. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder or the reasonableness of Expenses, the person or
persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement and that Expenses actually incurred are reasonable, if Indemnitee has submitted a notice and a request for indemnification
or advancement, as applicable, in accordance with Section 10 of this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither the failure of the
Company (including by the Board) or of Independent Counsel to have made a determination prior to the commencement of any judicial proceeding or arbitration pursuant to this Agreement that indemnification is proper in the circumstances because
Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by the Board) or by Independent Counsel that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (b) If the person, persons or entity
empowered or selected under Section 11 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of Indemnitee’s written
request for indemnification pursuant to Section 10(c) of this Agreement, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a
misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such
indemnification under applicable law; provided, however, that (x) such 60-day period may be extended for a reasonable time if Indemnitee is not reasonably cooperating with the person, persons or entity making such determination
and/or (y) such 60-day period may be extended for a reasonable time not to exceed an additional thirty (30) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in good faith
requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto. 
 (c) The
termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of
itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company
or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 
  

 -9- 

 (d) Reliance as Safe Harbor. For purposes of any determination of good faith,
Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action or failure to act is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the
officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or
other expert selected by the Enterprise. The provisions of this Section 12(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found to have met the applicable standard of
conduct set forth in this Agreement. 
 (e) Actions of Others. The knowledge and/or actions, or failure to act, of any
other director, trustee, general partner, managing member, officer, incorporator, employee, agent or fiduciary of the Enterprise shall not be imputed to Indemnitee for purposes of determining Indemnitee’s right to indemnification under this
Agreement. 
 13. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 11 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 9 or 10(b) of this Agreement, (iii) payment of indemnification is not made pursuant to Section 5, 6, 7 or the second to
last sentence of Section 11(a) of this Agreement within thirty (30) days after receipt by the Company of a written request therefor, or (iv) payment of indemnification pursuant to Section 3 or 4 of this Agreement is not made
within thirty (30) days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to seek an adjudication by a court of competent jurisdiction as to Indemnitee’s entitlement to such
indemnification or advancement of Expenses. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration
Association. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 
 (b)
In the event that a determination shall have been made pursuant to Section 11(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration, commenced pursuant to this Section 13, shall be
conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. 

(c) If a determination shall have been made pursuant to Section 11(a) of this Agreement that Indemnitee is entitled to
indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material
fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) If it shall be determined in said judicial adjudication or arbitration that Indemnitee is entitled to receive all or part of the
indemnification or advancement of Expenses 
  

 -10- 

 
sought, Indemnitee shall be entitled to recover from the Company (who shall be liable therefor), and shall be indemnified by the Company against, any and all Expenses reasonably incurred by
Indemnitee in connection with such judicial adjudication or arbitration. 
 (e) The Company shall be precluded from asserting in
any judicial proceeding or arbitration commenced pursuant to this Section 13 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that
the Company is bound by all the provisions of this Agreement. 
 14. Non-Exclusivity; Survival of Rights; Insurance.

 (a) The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed
exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Company’s or any other Enterprise’s Certificate of Incorporation, bylaws or similar organizational documents, any agreement, a vote of
stockholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted
by such Indemnitee in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses
than would be afforded currently under the Company’s or any other Enterprise’s Certificate of Incorporation, bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater
benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder
or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, trustees,
general partners, managing members, officers, incorporators, employees, agents or fiduciaries of the Company or of any other Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum
extent of the coverage made available to any other such director, trustee, general partner, managing member, officer, incorporator, employee, agent or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim
pursuant to Section 10(a) hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such Proceeding to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.

 15. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten
(10) years after the date that Indemnitee shall have ceased to serve as a director of the Company or as a director, trustee, general partner, managing member, officer, 

 

 -11-

“Recapitalization Agreement”) dated as of February 20, 2004, pursuant to which Holdings and Foreign Holdings acquired shares of the Company’s Preferred Stock and the Company was recapitalized in accordance with the terms

 SECTION 1.
COVENANTS, REPRESENTATIONS AND WARRANTIES 
 Each Investor, severally and not jointly, covenants, represents and warrants that:
(i) this Agreement has been duly authorized, executed and delivered by such Investor and constitutes the valid and binding obligation of such Investor, enforceable in accordance with its terms; (ii) following the consummation of the
transactions occurring concurrently herewith as contemplated by the Securities Purchase Agreement, such Investor shall be the record and beneficial owner of the shares of Company capital stock and/or the Notes, set forth next to such Investor’s

which such Investor is the record or beneficial owner; and (iii) other than as set forth in the Securities Purchase Agreement or herein, such Investor has not granted and is not a party to any proxy, voting trust or voting agreement or any

with, conflicts with or violates any provision of this Agreement. 
 SECTION 2. RESTRICTIONS ON TRANSFER OF SUBJECT
SECURITIES 
 2A. Restrictions on Transfer. No Investor shall sell, transfer, assign, pledge or otherwise directly
or indirectly dispose of (whether with or without consideration and whether 
  

 2 

 
voluntarily or involuntarily or by operation of law) (a “Transfer”) any interest in any Stockholder Shares or Notes (collectively, “Subject Securities”), except
(i) in the case of the Indigo Investors and the Oaktree Investors, pursuant to and in accordance with the provisions of Section 2B(i) or Section 2C, (ii) in the case of the Co-Investors, pursuant to and in
accordance with the provisions of Section 2B(ii) or Section 2C, or (iii) pursuant to an Exempt Transfer (as defined in Section 2D); provided, however, notwithstanding the foregoing, other than
pursuant to an Exempt Transfer, neither the Indigo Investors or the Oaktree Investors may Transfer any of their shares of Common Stock until after December 31, 2009, without the prior written consent of the Oaktree Investors or the Indigo
Investors, respectively. In no event shall any holder of shares of Class A Common Stock Transfer any shares of Class A Common Stock if such Transfer would result in the Company losing its status as a COUS. 

2B. Right of First Negotiation – Certain Transfers. 

(i) In the event either an Oaktree Investor or an Indigo Investor desires to Transfer any Subject Securities (a “Transferring
Holder”) (other than (a) any Transfer by an Oaktree Investor or an Indigo Investor pursuant to the exercise of such Investor’s rights under Section 2C or (b) any Exempt Transfer by an Oaktree Investor or an Indigo
Investor under Section 2D), such Transferring Holder shall deliver a written notice (the “Transfer Notice”) to the Company and the Majority Indigo Holder(s) (in the case of a desired Transfer by an Oaktree Investor) or
to the Company and the Majority Oaktree Holder(s) (in the case of a desired Transfer by an Indigo Investor (Indigo or Oaktree, as the case may be, each a “ROFO Offeree”)). For the avoidance of doubt, the right of first offer
provided for hereby applies only to the type and class of security specified in the applicable Transfer Notice. The Transfer Notice shall disclose the proposed number, type and class of Subject Securities to be Transferred (all such Securities, the
“Transfer Securities”). If, following the delivery of the Transfer Notice, a ROFO Offeree is interested in purchasing all of the Transfer Securities, such ROFO Offeree shall, within five (5) days thereafter, deliver a written
notice to the Transferring Holder expressing such ROFO Offeree’s interest in entering into negotiations with the Transferring Holder with respect to the purchase of all of the Transfer Securities (the “Expression of Interest”).
Thereafter, for a period of fifteen (15) days following the delivery of the Expression of Interest (the “Negotiation Period”), the Transferring Holder and such ROFO Offeree shall engage in good faith discussions with respect to
the terms of a Transfer of the Transfer Securities, provided that the Transferring Holder shall have no obligation to sell the Transfer Securities to such ROFO Offeree and such ROFO Offeree shall have no obligation to purchase the Transfer
Securities, until such time as definitive agreements are entered into by such parties. In the event that no agreement to Transfer the Transfer Securities to one or more ROFO Offeree(s) is reached within the Negotiation Period, then the Transferring
Holder shall deliver a written notice to the Company that no agreement has been reached and, thereafter, the Company shall have five (5) days to deliver a written notice to the Transferring Holder expressing its interest in entering into
negotiations with the Transferring Holder with respect to the proposed Transfer of the Transfer Securities (the “Company Expression of Interest”). Thereafter, for a period of fifteen (15) days following the delivery of the
Company Expression of Interest (the “Company Negotiation Period”), the Transferring Holder and the Company shall engage in good faith discussions with respect to the terms of a purchase of all of the Transfer Securities, provided
that the Transferring Holder shall have no obligation to sell the Transfer Securities to the Company and the Company shall have no obligation to purchase the Transfer Securities, until such time as definitive

  

 3 

 
agreements are entered into by such parties. If, following good faith discussion, no agreement is reached between the Transferring Holder, on the one hand, and either the ROFO Offeree(s) or the
Company, on the other hand, with respect to the Transfer of the Transfer Securities, the Transferring Holder may, during the ninety (90) day period immediately following the expiration of the Company Negotiation Period, Transfer the Transfer
Securities to any other Person, provided, that in the event that a price to purchase all of the Transfer Securities is offered by a ROFO Offeree or the Company in the course of the Negotiation Period or Company Negotiation Period, as the case may
be, in a binding written offer, which offer is capable of being accepted by the Transferring Holder and otherwise on customary terms and conditions for a transaction of this type, and such price is payable in full in cash at closing and the
Transferring Holder elected not to accept such offer, the price at which the Transferring Holder may Transfer such Transferring Holder’s shares shall be no less than the price so offered. In the event the Transfer Securities are not transferred
in such manner within such 90-day period, the Transfer Securities shall be subject to the provisions of this Section 2B(i) in connection with any subsequent Transfer or proposed Transfer by an Oaktree Investor or an Indigo Investor, as
the case may be. Any ROFO Offeree who engages in good faith discussions with the Transferring Holder with respect to the Transfer of the Transfer Securities and ultimately purchases Transfer Securities from the Transferring Holder may designate, by
written notice to the Company and the Majority Indigo Holder(s) or the Majority Oaktree Holder(s), as the case may be, at least fifteen (15) days prior to the consummation of such purchase, one or more other Persons to purchase all or any
portion of the Transfer Securities that such ROFO Offeree has elected to purchase. 
 (ii) In the event a Co-Investor desires to
Transfer any Subject Securities (a “Co-Investor Transferring Holder”) (other than (a) any Transfer by a Co-Investor pursuant to the exercise of such Co-Investor’s rights under Section 2C or (b) any Exempt
Transfer by a Co-Investor under Section 2D), such Co-Investor Transferring Holder shall deliver a written notice (the “Co-Investor Transfer Notice”) to the Company, the Majority Indigo Holder(s) and the Majority Oaktree
Holder(s) (each a “Co-Investor ROFO Offeree”)). For the avoidance of doubt, the right of first offer provided for hereby applies only to the type and class of security specified in the applicable Transfer Notice. The Transfer Notice
shall disclose the proposed number, type and class of Subject Securities to be Transferred (all such Securities, the “Co-Investor Transfer Securities”). If, following the delivery of the Co-Investor Transfer Notice, a Co-Investor
ROFO Offeree is interested in purchasing all of the Transfer Securities, such ROFO Offeree shall, within five (5) days thereafter, deliver a written notice to the Co-Investor Transferring Holder expressing such Co-Investor ROFO Offeree’s
interest in entering into negotiations with the Co-Investor Transferring Holder with respect to the purchase of all of the Co-Investor Transfer Securities (the “Co-Investor Expression of Interest”). Thereafter, for a period of
fifteen (15) days following the delivery of the Co-Investor Expression of Interest (the “Co-Investor Negotiation Period”), the Co-Investor Transferring Holder and such Co-Investor ROFO Offeree shall engage in good faith
discussions with respect to the terms of a Transfer of the Co-Investor Transfer Securities, provided that the Co-Investor Transferring Holder shall have no obligation to sell the Co-Investor Transfer Securities to such Co-Investor ROFO Offeree and
such Co-Investor ROFO Offeree shall have no obligation to purchase the Co-Investor Transfer Securities, until such time as definitive agreements are entered into by such parties. In the event more than one Co-Investor ROFO Offeree delivers an
Expression of Interest, the Co-Investor Transfer Securities shall be allocated among such Co-Investor ROFO Offerees pro rata according to the number of applicable Subject Securities owned by each such Co-Investor ROFO Offeree and

  

 4 

 
each Co-Investor ROFO Offeree shall have the right to engage in the good faith negotiations with respect to the terms of a purchase of all such Co-Investor Transfer Securities by such Co-Investor
Transferring Holder. In the event that no agreement to Transfer the Co-Investor Transfer Securities to one or more Co-Investor ROFO Offeree(s) is reached within the Co-Investor Negotiation Period, then the Co-Investor Transferring Holder shall
deliver a written notice to the Company that no agreement has been reached and, thereafter, the Company shall have five (5) days to deliver a written notice to the Co-Investor Transferring Holder expressing its interest in entering into
negotiations with the Co-Investor Transferring Holder with respect to the proposed Transfer of the Co-Investor Transfer Securities (the “Co-Investor Company Expression of Interest”). Thereafter, for a period of fifteen
(15) days following the delivery of the Co-Investor Company Expression of Interest (the “Co-Investor Company Negotiation Period”), the Co-Investor Transferring Holder and the Company shall engage in good faith discussions with
respect to the terms of a purchase of all of the Co-Investor Transfer Securities, provided that the Co-Investor Transferring Holder shall have no obligation to sell the Co-Investor Transfer Securities to the Company and the Company shall have no
obligation to purchase the Co-Investor Transfer Securities, until such time as definitive agreements are entered into by such parties. If, following good faith discussion, no agreement is reached between the Co-Investor Transferring Holder, on the
one hand, and either the Co-Investor ROFO Offeree(s) or the Company, on the other hand, with respect to the Transfer of the Co-Investor Transfer Securities, the Co-Investor Transferring Holder may, during the ninety (90) day period immediately
following the expiration of the Co-Investor Company Negotiation Period, Transfer the Co-Investor Transfer Securities to any other Person, provided, that in the event that a price to purchase all of the Co-Investor Transfer Securities is offered by a
Co-Investor ROFO Offeree or the Company in the course of the Co-Investor Negotiation Period or Co-Investor Company Negotiation Period, as the case may be, in a binding written offer, which offer is capable of being accepted by the Co-Investor
Transferring Holder and otherwise on customary terms and conditions for a transaction of this type, and such price is payable in full in cash at closing and the Co-Investor Transferring Holder elected not to accept such offer, the price at which the
Co-Investor Transferring Holder may Transfer such Co-Investor Transferring Holder’s shares shall be no less than the price so offered. In the event the Co-Investor Transfer Securities are not transferred in such manner within such 90-day
period, the Co-Investor Transfer Securities shall be subject to the provisions of this Section 2B(ii) in connection with any subsequent Transfer or proposed Transfer by a Co-Investor. Any Co-Investor ROFO Offeree who engages in good
faith discussions with the Co-Investor Transferring Holder with respect to the Transfer of the Co-Investor Transfer Securities and ultimately purchases Co-Investor Transfer Securities from the Co-Investor Transferring Holder may designate, by
written notice to the Company and the other Investors, at least fifteen (15) days prior to the consummation of such purchase, one or more other Persons to purchase all or any portion of the Co-Investor Transfer Securities that such Co-Investor
ROFO Offeree has elected to purchase. 
 2C. Participation Rights on Investor Transfers. 

(i) At least fifteen (15) days prior to any Transfer of any Subject Securities by either an Oaktree Investor or an Indigo Investor
(other than (a) any Transfer by an Oaktree Investor or an Indigo Investor as a Participating Stockholder pursuant to this Section 2C or (b) any Exempt Transfer by an Oaktree Investor or an Indigo Investor under
Section 2D), such Oaktree Investor or Indigo Investor, as the case may be, shall deliver a written notice (the “Tag-Along Sale Notice”) 

 

 5 

 
to the Company and each other Investor, as applicable, disclosing in reasonable detail the proposed number, type and class of Subject Securities that such Oaktree Investor or Indigo Investor, as
the case may be, proposes to Transfer (the “Tag-Along Securities”). Such entity delivering a Tag-Along Sale Notice is referred to herein as a “Proposed Seller” and the recipient of the Tag-Along Sale Notice, other
than the Company, is referred to herein as a “Tagging Holder.” Subject to the terms of this Section 2C, in the event such Proposed Seller is obligated to deliver a Tag-Along Sale Notice, the Tagging Holder that holds the
applicable class or type (regardless of tranche) of Subject Securities may elect to participate in such proposed Transfer by delivering, within ten (10) days after delivery of the Tag-Along Sale Notice, written notice to such Proposed Seller
and the Company stating that such Tagging Holder has elected to participate in such Transfer, the number of securities held by such Tagging Holder of each class and type of Tag-Along Securities and the number of securities of each such class and
type which such Tagging Holder proposes to sell in such Transfer (each such Tagging Holder who so elects to participate in such Transfer, a “Participating Holder”). If the other Tagging Holder elects to participate in such Transfer,
such Proposed Seller and the Participating Holders shall each be entitled to sell in such Transfer, at the price per security and on the terms described in this Section 2C, a number of Subject Securities equal, in the case of Stockholder
Shares, to the product of (1) the quotient of the number of Stockholder Shares constituting Tag-Along Securities divided by the total number of Stockholder Shares held by all Investors participating in such Transfer, multiplied by (2) the
number of Stockholder Shares constituting Tag-Along Securities held by such Investor, and, in the case of Notes, to the product of (1) the quotient of the aggregate principal amount of the Notes constituting Tag-Along Securities divided by the
total aggregate principal amount of the Notes held by all Investors participating in such Transfer, multiplied by (2) the aggregate principal amount of the Notes constituting Tag-Along Securities held by such Investor. 

(ii) Such Proposed Seller will use reasonable efforts to obtain the agreement of the prospective transferee(s) to the participation of
the Participating Holders in any contemplated Transfer, and shall not consummate any such Transfer unless each Participating Holder is permitted to sell the Subject Securities which such Participating Holder is entitled to sell hereunder
(“Participating Securities”) in such Transfer in the amount and on the terms set forth in this Section 2C (provided that if the prospective transferee(s) declines to allow the participation of any Participating
Holder, as an alternative, such Proposed Seller may consummate the proposed Transfer so long as contemporaneously therewith such Proposed Seller offers to purchase, and assuming the prompt acceptance of such offer and cooperation by such
Participating Holder, such Proposed Seller purchases, the Participating Securities from such Participating Holder at the price and on the other economic terms on which such Participating Holder would otherwise have been entitled pursuant to this
Section 2C to sell such Participating Securities in such Transfer). Each Participating Holder transferring Participating Securities pursuant to this Section 2C shall (x) pay the expenses incurred by such Participating
Holder in connection with the Transfer as well as its Allocable Share (as defined below) of the expenses incurred by such Proposed Seller in connection with such Transfer, and (y) be obligated to join in any indemnification or other
obligations that such Proposed Seller agrees to provide in connection with such Transfer (except that, while each Participating Holder shall be obligated to make representations and warranties as to such Investor’s title to and ownership of
Subject Securities, authorization, execution and delivery of relevant documents by such Participating Holder, enforceability of relevant agreements against such Participating Holder and other matters

  

 6 

 
relating to such Participating Holder, to enter into covenants in respect of the proposed Transfer of such Investor’s Participating Securities and to enter into indemnification obligations
with respect to the foregoing, in each case to the extent that such Proposed Seller is similarly obligated in connection with its proposed Transfer of Subject Securities, no Participating Holder shall be obligated to enter into indemnification
obligations with respect to any of the foregoing to the extent relating to any representation or warranty by any other Investor in respect of such other Investor or such other Investor’s Subject Securities). For purposes of the foregoing, a
Participating Holder’s “Allocable Share” of expenses means that portion of such expenses which would be borne by such Participating Holder if the total amount of such expenses were allocated to such Proposed Seller and the
Participating Holders in proportion to the gross proceeds received by such Participating Holder in respect of the Subject Securities included by such Participating Holder in such Transfer relative to the total gross proceeds received by the Proposed
Seller and all Participating Holders in such Transfer. 
 2D. Permitted Transfers. 

The restrictions set forth in this Section 2 shall not apply to any of the following Transfers of Subject Securities: 

(i) subject to the paragraphs below, any Transfer of Subject Securities by an Investor who is not an individual to any Affiliate of such
Investor; 
 (ii) in the case of Oaktree or Indigo or any other holder of Oaktree Securities or Indigo Securities, as the case
may be, any Transfer which constitutes an in-kind distribution by such Person to its partners or members; 
 (iii) subject to
the paragraphs below, in the case of an Investor who is an individual, (A) a Transfer of Subject Securities pursuant to the applicable laws of descent and distribution or (B) among such Investor’s Family Group; 

(iv) subject to the paragraphs below, in the case of a Co-Investor who is a limited liability company, among the Family Group of the
members of such Co-Investor; 
 (v) subject to the paragraphs below, any Transfer of Subject Securities held as of the date of
this Agreement by a Co-Investor to any Oaktree Investor(s); 
 (vi) any Transfer pursuant to an Approved Sale; 

(vii) any Public Sale; 

(viii) any redemptions and other repurchases of Preferred Stock by the Company in accordance with the Certificate of Incorporation or
Common Stock from an employee or director in connection with the termination of his or her employment or director status with the Company or any of its Subsidiaries; 

(ix) subject to the paragraphs below and to the prior written consent of Company, in the case of any Investor which is not an individual,
to a successor corporation or other successor entity as a result of a merger or consolidation with, or a sale of all or 

 

 7 

 
substantially all of the assets of, such Investor or, if a general or limited partnership or limited liability company, in connection with the liquidation and dissolution of such partnership or
limited liability company; and 
 (x) subject to the paragraphs below, any Transfer of Subject Securities by a Co-Investor to
any other Co-Investor. 
 A transferee of Subject Securities pursuant to a Transfer described in any of foregoing clauses (i),
(ii), (iii), (vii) and (viii) may be referred to herein as a “Permitted Transferee.” Not less than ten (10) days prior to any Transfer of Subject Securities pursuant to the foregoing clauses (i), (ii), (iii)(B),
(vii) and (viii), the proposed transferor and transferee will deliver a written notice to the Company, which notice will disclose in reasonable detail the nature of the proposed Transfer and the identity (including the identity of record and
beneficial owners in the event the proposed transferee is an entity) of the proposed transferee. In addition, notwithstanding anything to the contrary herein, the restrictions contained in this Agreement shall continue to be applicable to the
Subject Securities following any Transfer to a Permitted Transferee, and no Transfer to a Permitted Transferee may be consummated unless prior thereto the transferor thereof shall have complied with Section 7 below. 

Notwithstanding the foregoing, no Investor shall avoid the provisions of this Agreement by making one or more Transfers to one or more
Permitted Transferees and then disposing of all or any portion of such party’s interest in any such Permitted Transferee, and any Transfer or attempted Transfer in violation of this covenant shall be void and otherwise subject to
Section 7 below. In addition, and notwithstanding the foregoing, no Investor shall Transfer their Subject Securities if the Company would be in violation of any law, rule or regulation applicable to it as a result of such Transfer, and
any such Transfer or attempted Transfer in violation of this covenant shall be void and otherwise subject to Section 7 below. 

Any Transfer permitted pursuant to this Section 2D is referred to herein as an “Exempt Transfer.”

 2E. Termination of Restrictions. The restrictions set forth in this Section 2 shall continue with respect

SECTION 3. SALE OF THE COMPANY

 8 

 
Holder(s) in the case of an Approved Sale described in clause (x) of the definition of Approved Sale and the Majority Indigo Holder(s) in the case of an Approved Sale described in clause
(y) of the definition of Approved Sale. 
 3B. Required Actions. If the Approved Sale is structured as
(i) a merger or consolidation, each holder of Stockholder Shares shall vote its Stockholder Shares to approve such merger or consolidation, whether by written consent or at a stockholders meeting (as requested by the Dragging Holder(s)), and
waive all dissenter’s rights, appraisal rights and similar rights in connection with such merger or consolidation, (ii) a sale of stock, each holder of Stockholder Shares shall agree to sell, and shall sell, all of its Stockholder Shares
and rights to acquire Stockholder Shares on the terms and conditions so approved, or (iii) a sale of assets, each holder of Stockholder Shares shall vote its Stockholder Shares to approve such sale and any subsequent liquidation of the Company
or other distribution of the proceeds therefrom, whether by written consent or at a stockholders meeting (as requested by the Dragging Holder(s)). In furtherance of the foregoing, (a) each holder of Stockholder Shares will take, with respect to
such holder’s Stockholder Shares, all necessary or desirable actions reasonably requested by the Dragging Holder(s) in connection with the consummation of the Approved Sale of the Company and (b) each holder of Stockholder Shares will make
the same representations, warranties, indemnities and agreements as each other holder (subject to Sections 3B(1) and (2) below), including without limitation, voting to approve such transaction and executing the applicable
purchase agreement. In any Approved Sale, (1) each holder of Stockholder Shares shall be obligated to make representations and warranties as to such holder’s title to and ownership of Stockholder Shares, authorization, execution and
delivery of relevant documents by such holder of Stockholder Shares, enforceability of relevant agreements against such holder of Stockholder Shares and other matters relating to such holder of Stockholder Shares, to enter into covenants in respect
of a Transfer of such holder’s Stockholder Shares in connection with such Approved Sale and to enter into indemnification obligations with respect to the foregoing, in each case to the extent that each other holder of Stockholder Shares is
similarly obligated; provided that no holder of Stockholder Shares shall be obligated to enter into indemnification obligations with respect to any representations, warranties or covenants in the nature of those described in this clause
(1) to the extent relating to or in respect of any other holder of Stockholder Shares or any other holder’s Stockholder Shares, and (2) in no event shall any holder of Stockholder Shares be liable in respect of any indemnity
obligations pursuant to any Approved Sale in an aggregate amount in excess of the total consideration payable to such holder of Stockholder Shares in such Approved Sale. 

3C. Conditions to Stockholders’ Obligations. The obligations of the holders of Stockholder Shares with respect to an
Approved Sale are subject to the satisfaction of the following conditions: (i) upon the consummation of the Approved Sale, each holder of Stockholder Shares will receive the same form of consideration and the same portion of the aggregate
consideration that such holders of Stockholder Shares would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Certificate of
Incorporation as in effect immediately prior to such Approved Sale; (ii) if any holders of a class of Stockholder Shares are given an option as to the form and amount of consideration to be received, each holder of such class of Stockholder
Shares will be given the same option; and (iii) each holder of then currently exercisable rights to acquire shares of a class of Stockholder Shares will be given an opportunity to exercise such rights prior to the consummation of the Approved
Sale and participate in such sale as holders of such class of Stockholder Shares.

 3D. Rule 506 Transaction. If the Company or the Dragging Holder(s) enter into
any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities Exchange Commission may be available with respect to such negotiation or transaction (including a merger, consolidation or other
reorganization), each holder of Stockholder Shares will, at the request of the Company or the Dragging Holder(s), appoint a purchaser representative (as such term is defined in Rule 501) reasonably acceptable to the Company and the Dragging
Holder(s). If any holder of Stockholder Shares appoints a purchaser representative designated by the Company or the Dragging Holder(s), the Company will pay the fees of such purchaser representative, but if any holder of Stockholder Shares declines
to appoint the purchaser representative designated by the Company such holder will appoint another purchaser representative, and such holder will be responsible for the fees of the purchaser representative so appointed. 

3E. Expenses of Approved Sale. Holders of Stockholder Shares will bear their pro rata share (based on total gross proceeds
received by all holders of Stockholder Shares sold pursuant to the Approved Sale) of the costs of any sale of Stockholder Shares pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all holders of Stockholder Shares
and are not otherwise paid by the Company or the acquiring party. For purposes of this Section 3E, costs incurred in exercising reasonable efforts to take all necessary actions in connection with the consummation of an Approved Sale in
accordance with Section 3A shall be deemed to be for the benefit of all holders of Stockholder Shares, except that costs incurred by any holder of Stockholder Shares in connection with the Transfer of its own shares or otherwise on its
own behalf will not be considered costs of the transaction hereunder and will be the responsibility of such holder. 

3F. Stock Powers. Prior to or concurrently with the execution of this Agreement (and promptly after the acquisition of any
additional Stockholder Shares), each New Securityholder and Co-Investor shall deliver to the Company (i) all certificates evidencing any Stockholder Shares owned by such New Securityholder and Co-Investor and (ii) five stock transfer
powers in the form of Exhibit B attached hereto (each, a “Stock Power” and, collectively, the “Stock Powers”) executed in blank with respect to all such Stockholder Shares. All certificates evidencing such
Stockholder Shares will be held by the Company for the benefit of such New Securityholders and Co-Investors until consummation of an Approved Sale in accordance with the terms and conditions of this Section 3. In connection with any such
Approved Sale, the Company is hereby authorized by each such New Securityholder and Co-Investor to assign, transfer and deliver all such Stockholder Shares to the appropriate acquiror thereof in accordance with the terms and conditions of this
Section 3. In the event of a Transfer by any New Securityholder or Co-Investor pursuant to and in compliance with the provisions of this Agreement, the Company shall use its commercially reasonable efforts to cancel and reissue any
certificates held by it in order to evidence such Transfer as soon as reasonably practicable. 
 3G. Termination.
The rights and obligations under this Section 3 shall terminate, and the Company shall return all certificates and Stock Powers delivered to the Company pursuant to Section 3F to the record holder of such Stockholder Shares
(to the extent not previously transferred in connection with an Approved Sale), upon the first to occur of (a) the consummation of a Qualified Public Offering or (b) the consummation of an Approved Sale.

 SECTION 4. PREEMPTIVE RIGHTS 

4A. Offering. 

(i) If the Company issues or sells or authorizes the issuance or sale of any New Securities (as defined in Section 4C below)
after the date hereof, the Company shall offer to each holder of Stockholder Shares by written notice (an “Offer Notice”) a percentage of such New Securities equal to the percentage result of the quotient determined by dividing
(a) the number of shares of Common Stock held by such holder on a Fully Diluted Basis, by (b) the aggregate number of outstanding shares of Common Stock on a Fully Diluted Basis. Each such holder of Stockholder Shares shall be entitled to
purchase such New Securities at the most favorable price and on the most favorable terms as such New Securities are to be sold or issued; provided that if a Person participating in such purchase of New Securities is required in connection
therewith also to purchase other securities of the Company, the holders of Stockholder Shares exercising their rights pursuant to this Section 4A shall also be required to purchase such other securities on the same economic terms and
conditions as those on which the offeree of the New Securities is required to purchase such other securities (e.g., such holder shall be required to purchase the same types and classes of other securities, in the same proportions relative to their
purchases of New Securities and at the same unit prices). For example, if the Company offers to sell shares of Common Stock and requires that, in connection with purchasing specified amounts of shares of Common Stock, the offeree of such Common
Stock must also purchase a specified number of shares of Preferred Stock, holders of Common Stock exercising rights to purchase shares of Common Stock pursuant to this Section 4A would be obligated also to purchase, at the same price per
share of Preferred Stock, a proportionate number of shares of Preferred Stock. Each holder of Stockholder Shares participating in such purchase shall also be obligated to execute agreements in the form presented to such holder by the Company, so
long as such agreements are substantially similar to those to be executed by other purchasers of New Securities (without taking into consideration any rights which do not entitle such a purchaser to a higher economic return on the New Securities
than the economic return to which the other holders of Common Stock participating in such transaction will be entitled with respect to New Securities). The purchase price for all New Securities offered to each holder of Stockholder Shares shall be
payable in cash by wire transfer of immediately available funds to an account designated by the Company. Notwithstanding anything to the contrary contained herein, the Company shall not have any obligation to issue equity securities or to offer to
issue any equity securities under this Section 4 to any holder of Stockholder Shares who is not an “accredited investor” as such term is defined in Regulation D under the Securities Act. 

(ii) Each Offer Notice delivered by the Company to a holder of Stockholder Shares in respect of any proposed issuance or sale of New
Securities shall describe in reasonable detail the type, class and number of New Securities being offered, the purchase price thereof, the payment terms therefor and the percentage thereof offered to such holder pursuant to this
Section 4. In order to exercise its purchase rights hereunder in respect of any issuance or sale of New Securities described in an Offer Notice, a holder of Stockholder Shares must deliver to the Company, during the 15-day period
commencing upon such holder’s receipt of such Offer 
  

 11 

 
Notice (the “Offering Period”), a written commitment describing its election hereunder (an “Election Notice”). If a holder of Stockholder Shares fails for any
reason to deliver an Election Notice to the Company during the Offering Period with respect to a proposed issuance or sale of New Securities, such holder shall be deemed to have waived its rights pursuant to this Section 4 in respect of
such issuance or sale of New Securities. 
 4B. Expiration of Offering Period. Within the 180-day period
immediately following the Offering Period, the Company shall be entitled to sell any New Securities which any holder of Stockholder Shares has not elected to purchase, on terms and conditions no more favorable to the offeree of such New Securities
than those offered to holders of Stockholder Shares pursuant to Section 4A. Any New Securities offered or sold by the Company after such 180-day period must be reoffered to each holder of Stockholder Shares pursuant to the terms of this
Section 4. 
 4C. New Securities. For purposes hereof, “New Securities” means any
shares of the Company’s capital stock, or any options, warrants, convertible or exchangeable securities or other rights to acquire shares of the Company’s capital stock of any type whatsoever (including, without limitation, (x) debt
obligations which are convertible or exchangeable into capital stock of the Company and (y) contractual rights to receive payments, such as “phantom” stock or stock appreciation rights, where the amount thereof is determined by
reference to fair market or equity value of the Company), other than any (i) securities issued in connection with the transactions contemplated by the Securities Purchase Agreement, (ii) Class B Common Stock (or options to acquire Class B
Common Stock) issued to any employee of the Company or any of its Subsidiaries pursuant to any equity incentive plan or other arrangement approved by the Company’s board of directors, (iii) Common Stock or other securities issued directly
or indirectly upon the conversion, exchange or exercise of any securities previously subject to this Section 4, (iv) Common Stock or other securities issued in connection with or in furtherance of the acquisition of or investment in
another company or business (whether through a purchase of securities, a merger, consolidation, purchase of assets or otherwise), (v) Common Stock or other securities issued to entities that are not Affiliates of the Company in connection with
or in furtherance of the incurrence of any indebtedness for borrowed money, leases or purchase money interests by the Company or any of its Subsidiaries, (vi) Common Stock or other securities issued in a Public Offering or a Public Sale,
(vii) Common Stock or other securities issued in connection with any stock split, dividend, combination, recapitalization or similar transaction, (viii) Common Stock or other securities issued to entities that are not Affiliates of the
Company in connection with or in furtherance of commercial credit arrangements, real estate transactions, equipment financings or similar transactions, or (ix) Common Stock or other securities issued directly or indirectly upon the conversion,
exchange or exercise of any securities issued pursuant to any of the clauses of this Section 4C. 
 4D.
Termination. The rights under this Section 4 shall terminate upon the first to occur of (i) the consummation of a Public Offering, and (ii) the consummation of an Approved Sale. 

 

 12 

 SECTION 5. PUBLIC OFFERING 

In the event that the Board approves an initial Public Offering, each Investor shall use reasonable efforts to take all necessary or
desirable actions in connection with the consummation of such Public Offering. In the event that such Public Offering is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the existing capital
structure of the Company will adversely affect the marketability of the offering, each holder of Stockholder Shares will consent to and vote for a split, reverse split or other combination or reverse combination of Common Stock that the managing
underwriters and the Board find acceptable and will take all other necessary or desirable actions in connection therewith; provided that the resulting securities reflect and are consistent with the rights and preferences among the outstanding
classes of securities set forth in the Certificate of Incorporation as in effect immediately prior to such split, reverse split or other combination or reverse combination of Common Stock; provided, further, that all holders of
Stockholder Shares are treated similarly in proportion to their stock holdings. 
 SECTION 6. LEGEND 

Each certificate evidencing Subject Securities issued prior to, as of or following the date hereof and each securities certificate issued
in exchange for or upon the transfer of any Subject Securities (if such shares remain Subject Securities as defined herein after such Transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form: 

“THE SECURITIES REPRESENTED [BY THIS CERTIFICATE] [HEREBY] ARE SUBJECT TO CERTAIN TRANSFER RESTRICTIONS PURSUANT TO A SECOND AMENDED
AND RESTATED INVESTOR RIGHTS AGREEMENT DATED AS OF JULY 13, 2006, AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S SECURITY HOLDERS. A COPY OF SUCH SECOND AMENDED AND RESTATED INVESTOR RIGHTS AGREEMENT
WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST TO THE COMPANY’S CHIEF FINANCIAL OFFICER.” 

The legend set forth above shall be promptly removed from the securities certificates evidencing any Subject Securities for which the
restrictions contained in Section 2 have terminated in accordance with Section 2E hereof. 
 SECTION
7. TRANSFER 
 Prior to consummating, or committing to consummate, any Transfer of any Subject Securities (in compliance with
(i) in the case of the Indigo Investors and the Oaktree Investors, pursuant to and in accordance with the provisions of Section 2B(i) or Section 2C, (ii) in the case of the Co-Investors, pursuant to and in
accordance with the provisions of Section 2B(ii) or Section 2C, or (iii) in the case of each Investor, pursuant to an Exempt Transfer 

 

 13 

 
(as defined in Section 2D) and other than pursuant to a Public Sale or an Approved Sale) to any Person, the Transferring Holder shall cause each prospective transferee thereof to
execute and deliver to the Company a Joinder Agreement, the form of which is attached to this Agreement as Exhibit A. Any Transfer or attempted Transfer of any Subject Securities in violation of the foregoing or any other provision of this
Agreement shall be void, and the Company shall not record such Transfer on its books or treat any purported transferee of such Subject Securities as the owner of such securities for any purpose. 

SECTION 8. BOARD OF DIRECTORS; VOTING 

8A. Composition of the Board. From and after the effectiveness of this Agreement and until the provisions of this
Section 8 cease to be effective, each holder of Stockholder Shares shall vote all of his, her or its Stockholder Shares and any other voting securities of the Company over which such holder of Stockholder Shares has voting control
(whether at a stockholders’ meeting which has been duly called, or if so requested by the Company, by written consent) and shall take all other necessary or desirable actions within his, her or its control (whether in the capacity as a
stockholder, director, member of a Board committee or officer of the Company or otherwise, and including, without limitation, attendance at meetings in person or by proxy for purposes of obtaining a quorum and execution of written consents in lieu
of meetings), and the Company shall take all necessary and desirable actions within its control (including, without limitation, calling special board and stockholder meetings), so that: 

(i) the authorized number of directors on the Company’s Board shall be established at seven (7) directors; 

(ii) the following persons shall be elected to the Board: 

 

	 	(a)	two (2) persons designated by Indigo Florida, who initially shall be Mr. Stephen L. Johnson and Mr. Horacio Scapparone; 

 

	 	(b)	two (2) persons designated by Indigo Miramar, each of whom shall be a COUS and who initially shall be Mr. William A. Franke and Mr. Barclay Jones

	 	(c)	one (1) person designated by POF II and one (1) person designated by POF III (collectively, the “Existing Investor Directors” and each,
individually, an “Existing Investor Director”), each of whom shall be a COUS and who shall initially be Mr. Jordon Kruse (designated by POF II) and Mr. Stuart Oran (designated by POF III); and 

 

	 	(d)	the then-current CEO of the Company, who shall be a COUS and shall initially be Mr. Benjamin Baldanza (the “CEO Director”).

  

 14 

 (iii) the Indigo Miramar Directors shall be entitled to designate the Chairman of the Board;

 (iv) except to the extent otherwise requested in writing by the Majority Existing Investor Holders(s), each committee of the
Board shall contain at least one (1) Existing Investor Director; 
 (v) unless composed solely of employees of the Company,
the composition of the board of directors of each of the Company’s Subsidiaries (a “Sub Board”) shall be the same as that of the Board; 

(vi) an Indigo Investor Director shall be removed from the Board only upon the written request of the designating Indigo Investor;

 (vii) an Existing Investor Director shall be removed from the Board only upon the written request of the designating Existing
Investor; 
 (viii) in the event that any person designated as a director pursuant to any subparagraph of
Section 8A(ii) for any reason ceases to serve as a member of the Board or a Sub Board during such person’s term of office, the resulting vacancy on the Board or the Sub Board shall be filled by a representative designated by the
person originally entitled to designate such director pursuant to Section 8A(ii) above; and 
 (ix) the holders of
Stockholder Shares who, at the time of the election of directors, hold shares of Class A Common Stock agree that if an individual serving as the Company’s CEO ceases to serve in such capacity (whether voluntarily or involuntarily), each
holder of Stockholder Shares who, at the time of the election of directors, hold shares of Class A Common Stock will take such action as may be required so that all of the shares of Class A Common Stock held by the holders of Stockholder
Shares who, at the time of the election of directors, hold shares of Class A Common Stock are voted for the removal of such individual from the Board (whether by written consent or at an annual or special meeting of stockholders) and to elect
as the new CEO Director the person who replaces such individual as the CEO of the Company (whether by written consent or at an annual or special meeting of stockholders). 

To secure the obligations to vote the Stockholder Shares in accordance with this Section 8A, each holder of Stockholder
Shares hereby appoints the Chairman of the Board of Directors and the CEO of the Company, from time to time, or their designees, as such holder’s true and lawful proxy and attorney, with the power to act alone and with full power of
substitution, to vote all of such holder’s Stockholder Shares as set forth in this Section 8A and to execute all necessary actions by written consent of the holders of such Stockholder Shares consistent with this
Section 8A on behalf of such holder of Stockholder Shares if, and only if, such holder fails to vote all of such holder’s Stockholder Shares or execute such other necessary actions by written consent of the holders of such
Stockholder Shares in accordance with the provisions of Section 8A within five (5) days of the Company’s or any other party’s written request for such holder’s written consent or signature. The proxy and power granted
by each holder of Stockholder Shares pursuant to this Section 8A are coupled with an interest and are given to secure the performance of such party’s duties under this Section 8A. Each such proxy and power

  

 15 

 
will be irrevocable for the term of this Section 8. The proxy and power, so long as any party hereto is an individual, will survive the death, incompetency and disability of such
party or any other individual holder of the Stockholder Shares and, so long as any party hereto is an entity, will survive the merger or reorganization of such party or any other entity holding any Stockholder Shares. 

8B. Board Meeting Expenses. The Company shall pay all out-of-pocket expenses incurred by each non-employee director in
connection with attending regular and special meetings of the Board, any Sub Board (unless composed solely of employees of the Company) and any committee thereof. In addition, the Company may pay each non-employee director an annual director fee and
any other emoluments as compensation for service on the Board, such amount and other emoluments, if any, to be determined by the Board, but in all cases to be paid equally to all non-employee members of the Board. 

8C. Scheduling Meetings of the Board and Stockholders. Subject to the next two sentences of this Section 8C, any
director may call a meeting of the Board. A majority of the directors constituting the Board may call a meeting of the Board on three business days’ prior notice to the other directors. In the event that less than a majority of the directors
constituting the Board elect to call a meeting of the Board, then the meeting of the Board may be called with ten (10) business days’ prior notice to the other directors. A majority of the directors constituting the Board or the holders of
more than fifty percent of the outstanding principal amount of the Senior Secured Notes issued pursuant to the Note Purchase Agreement, dated May 11, 2005, and the Amended and Restated Securities Purchase Agreement, dated July 12, 2005,

SECTION 9. DEMAND REGISTRATIONS 

9A. Requests for Registration. At any time the holders of a majority of the Indigo Registrable Securities or the holders of
a majority of the Oaktree Registrable Securities may request registration under the Securities Act (a “Demand Registration”) of all or any portion of such holders’ Registrable Securities on Form S-1 or any similar
long-form registration (a “Long-Form Registration”) or, if available, on Form S-2 or S-3 or any similar short-form registration (a “Short-Form Registration”). Each request for a Demand Registration shall
specify the approximate number of Indigo Registrable Securities and/or Oaktree Registrable Securities requested to be registered and the anticipated per share price range for such offering. Within ten (10) days after receipt of any such
request, the Company will give written notice of such requested registration to all other holders of Oaktree Registrable Securities or Indigo Registrable Securities and, subject to Section 9D below, will include in such registration all
Oaktree Registrable Securities and/or Indigo Registrable Securities with respect to which the Company has received written requests for inclusion therein within fifteen (15) days after the receipt of the Company’s notice. 

9B. Long-Form Registrations. The holders of a majority of the Indigo Registrable Securities and holders of a majority of
the Oaktree Registrable Securities will each be entitled to request two (2) Long-Form Registrations in which the Company will pay all Registration Expenses. 

9C. Short-Form Registrations. In addition to the Long-Form Registrations provided pursuant to Section 9B, the
holders of a majority of the Indigo Registrable Securities and holders of a majority of the Oaktree Registrable Securities will be entitled to request unlimited Short-Form Registrations in which the Company will pay all Registration Expenses Demand
Registrations will be Short-Form Registrations whenever the Company is permitted to use any applicable short form. After the Company has become subject to the reporting requirements of the Securities Exchange Act, the Company will use its best
efforts to make Short-Form Registrations available for the sale of Oaktree Registrable Securities and Indigo Registrable Securities. 

9D. Priority on Demand Registrations. The Company will not include in any Demand Registration any securities which are not
Oaktree Registrable Securities or Indigo 
  

 22 

 
Registrable Securities without the prior written consent of the holders of a majority of the Indigo Registrable Securities if such holders initially requested such Demand Registration (in such
capacity, the “Initiating Holder”) or holders of a majority of the Oaktree Registrable Securities if such holder initially requested such Demand Registration (in such capacity, also the “Initiating Holders”). If a
Demand Registration is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of Oaktree Registrable Securities and Indigo Registrable Securities and, if permitted hereunder, other
securities requested to be included in such offering exceeds the number of Oaktree Registrable Securities and Indigo Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range
acceptable to the applicable Initiating Holder(s), the Company will include in such registration (i) first, the Oaktree Registrable Securities and Indigo Registrable Securities requested to be included in such registration, pro rata among the
holders of such Registrable Securities on the basis of the number of Registrable Securities owned by each such holder, and (ii) second, any other securities requested to be included in such registration which securities, in the opinion of such
underwriters, can be sold in an orderly manner within the price range of such offering; provided that, in the event the holders of a majority of the Indigo Registrable Securities or a majority of the Oaktree Registrable Securities, as
applicable, are not permitted as a result of such underwriter’s advice to include at least 80% of the Oaktree Registrable Securities and/or Indigo Registrable Securities initially requested to be included in such registration by such holders,
then such request and related registration shall not constitute one of the two (2) Long-Form Registrations to which the holders of a majority of the Indigo Registrable Securities or a majority of the Oaktree Registrable Securities, as
applicable, are entitled to request pursuant to this Section 9. 
 9E. Intentionally Omitted.

 9F. Restrictions on Demand Registrations. The Company will not be obligated to effect any Demand Registration
within six (6) months after the effective date of a previous Demand Registration. The Company may postpone for up to 60 days the filing or the effectiveness of a registration statement for a Demand Registration if the Board determines in its
good faith judgment that such Demand Registration would be seriously detrimental to the Company and its stockholders and would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any of its Subsidiaries
to engage in any acquisition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or similar transaction; provided that, in such event, the Initiating Holders will be entitled to withdraw such
request, and such request shall not constitute one of the two (2) Long-Form Registrations to which the holders of the Indigo Registrable Securities or Oaktree Registrable Securities, as applicable, are entitled pursuant to this
Section 9; and provided further that the Company may not utilize this right more than once in any 12-month period. 

9G. Selection of Underwriters. If any Demand Registration is an underwritten offering, the applicable Initiating Holders
will have the right to select the investment banker(s) and manager(s) for the offering. 
 9H. Other Registration
Rights. Except as provided in this Agreement, the Company will not grant to any Person the right to request the Company to register any equity securities of the Company (whether as a demand registration or a piggyback registration), or any

  

 23 

 
securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the holders of a majority of the Indigo Registrable Securities and holders of
a majority of the Oaktree Registrable Securities; provided that the consent of the holders of a majority of the Oaktree Registrable Securities shall be not be required if the Company grants such Person registration rights that are no less favorable
to the holders of the Oaktree Registrable Securities than the rights granted to such other Person. 
 9I. Demand
Registration Expenses. The Registration Expenses in connection with any Demand Registration will be paid by the Company, including the reimbursement of the holders of Registrable Securities included in such registration for the reasonable fees
and disbursements of one counsel chosen by the applicable Initiating Holder(s). 
 SECTION 10. PIGGYBACK REGISTRATIONS

 10A. Right to Piggyback. Whenever the Company proposes to register any of its securities under the Securities
Act (other than (i) in connection with the Company’s initial Public Offering, (ii) pursuant to a Demand Registration (but subject to the rights of holders of Registrable Securities to participate in Demand Registrations pursuant to
Section 9) or (iii) pursuant to a registration on Form S-4 or S-8 or any successor or similar forms) and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback
Registration”), the Company will give prompt (but in any event at least fifteen (15) days prior to the filing of any registration statement) written notice to all holders of Registrable Securities of its intention to effect such a
registration and will use its reasonable best efforts to include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within fifteen (15) days after the receipt of
the Company’s notice. Such written request may include all or a portion of the Registrable Securities held by a holder of Registrable Securities. 

10B. Piggyback Expenses. The Registration Expenses of the holders of Registrable Securities will be paid by the Company in
all Piggyback Registrations. 
 10C. Priority on Primary Registrations. If a Piggyback Registration
is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can
be sold in such offering in an orderly manner within a price range acceptable to the Company, the Company will include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities requested to
be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the number of shares owned by each such holder, and (iii) third, other securities requested to be included in such registration. 

10D. Other Registrations. If the Company has previously filed a registration statement with respect to Registrable
Securities pursuant to Section 9 or pursuant to this Section 10, and if such previous registration has not been withdrawn or abandoned, the Company will not file or cause to be effected any other registration of any of its
equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (except on Form S-4 or S-8 or any successor form), whether on its own behalf or at the request of any holder or
holders of such securities, until a period of at least sixty (60) days has elapsed from the effective date of such previous registration. 
  

 24 

 10E. Postponement or Withdrawal. If, at any time after giving written notice
of its intention to register any of its securities as set forth in Section 10A and prior to the effective date of such registration statement filed in connection with such registration, the Board shall determine in its good faith
judgment for any reason not to register such securities, the Company may, at its election, give written notice of such determination to each holder of Registrable Securities and thereupon shall be relieved of its obligation to register any
Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses incurred prior to such notice in connection therewith as provided herein). 

SECTION 11. HOLDBACK AGREEMENTS 

11A. Agreement of Holders of Subject Securities. To the extent not inconsistent with applicable law, each holder of Subject
Securities shall not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any equity securities of the Company, or any options or warrants to purchase equity securities of the Company, or
any securities convertible into, exchangeable for or that represent the right to receive equity securities of the Company, whether now owned or hereinafter acquired, owned directly by the holder (including holding as a custodian) or with respect to
which the holder has beneficial ownership within the rules and regulations of the Securities and Exchange Commission, during (a) with respect to the initial Public Offering, the seven days prior to and the 180-day period beginning on the
effective date of such Initial Public Offering, (b) with respect to any other underwritten Demand Registration or any underwritten Piggyback Registration in which Registrable Securities are included, the seven days prior to and the 90-day
period beginning on the effective date of such registration, and (c) upon notice from the Company of the commencement of an underwritten distribution in connection with any shelf registration, the seven days prior to and the 90-day period
beginning on the date of commencement of such distribution, in each case except as part of such underwritten registration, and in each case unless the underwriters managing the registered public offering otherwise agree (in each case, such period,
the “Lock-Up Period”); provided, however, if (i) during the period that begins on the date that is 15 calendar days plus three business days before the last day of the Lock-Up Period and ends on the last day of
the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (ii) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results
during the 16 day period beginning on the last day of the Lock-Up Period, the restrictions imposed shall continue to apply until the expiration of the date that is 15 calendar days plus three Business Days after the date on which the issuance of the
earnings release or the material news or material event occurs. Any waiver by the underwriters of the foregoing restrictions on transfers by the holders shall be granted to all holders on equal terms. 

11B. Agreement of the Company. The Company shall not offer, sell, contract to sell or otherwise dispose of any securities
of the Company, including but not limited to any securities that are convertible into or exchangeable for, or that represent the right to receive, equity securities or any such substantially similar securities, during (a) with respect to the
initial Public Offering, the seven days prior to and the 180-day period beginning on the effective date 
  

 25 

 
of such Initial Public Offering, (b) with respect to any other underwritten Demand Registration or any underwritten Piggyback Registration in which Registrable Securities are included, the
seven days prior to and the 90-day period beginning on the effective date of such registration, and (c) upon notice from any holder(s) of Registrable Securities subject to a shelf registration that such holder(s) intend to effect an
underwritten distribution of Registrable Securities pursuant to such shelf registration (upon receipt of which, the Company will promptly notify all other holders of Registrable Securities of the date of the commencement of such distribution), the
seven days prior to and the 90-day period beginning on the date of the commencement of such distribution, in each case except as part of such underwritten registration or pursuant to registrations on Form F-4, Form S-4 or Form S-8,
and in each case unless the underwriters managing the registered public offering otherwise agree. 
 SECTION 12.
REGISTRATION PROCEDURES

counsel for the underwriters a prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer or (ii) such shorter period as will terminate when all of the securities covered by such
registration statement have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement (but in any event not before the expiration of any longer period required
under the Securities Act), and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement until such time as all of such securities have been disposed of in accordance

the Securities Act, upon discovery that, or upon the discovery of the happening of any event as a result of which, the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to
make the statements therein not misleading in the light of the circumstances under which they were made, and, at the request of any such seller, the Company will prepare and file with the Securities and Exchange Commission and furnish without charge
to such seller a reasonable number of copies of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact
or omit to state any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made;

holder and its counsel should be included;

Act or by an underwriter, provide a legal opinion of the Company’s outside counsel, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, dated the date of the closing under

covering such matters of the type customarily covered by legal opinions of such nature. 
 The Company may require each seller of
Registrable Securities as to which any registration is being effected to furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request in writing as shall
be required by the Securities and Exchange Commission to effect the registration of the Registrable Securities. 
 SECTION
13. REPORTS UNDER SECURITIES EXCHANGE ACT 
 With a view to making available to the holders of Registrable Securities the
benefits of Rule 144 promulgated under the Act (“Rule 144”) and any other rule or regulation of the Securities and Exchange Commission that may at any time permit such holders to sell securities of the Company to the public without
registration or pursuant to a Short-Form Registration, the Company shall use its reasonable best efforts to: 
 (i) make and
keep public information available, as those terms are understood and defined in Rule 144, at all times after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public;

  

 28 

 (ii) file with the Securities and Exchange Commission in a timely manner all reports and
other documents required of the Company under the Act and the Securities Exchange Act; 
 (iii) furnish to the holder of

(90) days after the effective date of the first registration statement filed by the Company), the Act and the 1934 Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose
securities may be resold pursuant to Short-Form Registration (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and
(iii) such other information as may be reasonably requested in availing the holder of any rule or regulation of the Securities and Exchange Commission that permits the selling of any such securities without registration or pursuant to such
form; and 
 (iv) promptly deregister, if requested by holders of Indigo Registrable Securities, any Registrable Securities that
are not sold pursuant to a Demand Registration or Piggyback Registration after the Registration Statement relating thereto is no longer effective. 

SECTION 14. REGISTRATION EXPENSES 

14A. Company Expenses. Unless otherwise specifically provided in this Agreement, all expenses incident to the Company’s
performance of or compliance with this Agreement, including, without limitation, all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, and fees and

 29 

 SECTION 15. INDEMNIFICATION 

15A. Indemnification Obligation of the Company. The Company will indemnify and hold harmless, to the extent permitted by
law, each holder of Registrable Securities, its officers and directors and each Person, if any, who controls such holder (within the meaning of the Securities Act) against any losses, claims, damages, liabilities (joint or several) and expenses that
arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): (i) any untrue or alleged untrue statement of material fact contained in any registration statement,
prospectus or preliminary prospectus or any amendment thereof or supplement thereto, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or
(iii) any violation or alleged violation by the Company of the Securities Act, the Securities Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, or the Securities Exchange Act or any state
securities law, except in so far as any such Violation is caused by or contained in any information furnished in writing to the Company by or on behalf of such holder expressly for use therein or by such holder’s failure to deliver a copy of
the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same. The Company will pay to the holder of Registrable Securities or controlling
person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this
Section 15A shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld. In connection
with an underwritten offering, the Company will indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act or the Securities Exchange Act) to the same extent as
provided above with respect to the indemnification of the holders of Registrable Securities. 
 15B. Indemnification
of the Company. In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder will furnish to the Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, will indemnify and hold harmless the Company, its directors and officers and each other Person who controls the Company (within
the meaning of the Securities Act) against any losses, claims, damages, liabilities (joint or several) and expenses that arise out of or are based upon a Violation, but only to the extent that such Violation is caused by or contained in any
information or affidavit so furnished in writing by or on behalf of such holder expressly for use in connection with such registration; provided, however, that the indemnity agreement contained in this Section 15B shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the holder of Registrable Securities, which consent shall not be unreasonably withheld; provided
further that the obligation to indemnify will be individual to each holder and shall not exceed the amount by which the total price at which the Registrable Securities of such holder of Registrable Securities were offered to the public (less
underwriters’ discounts and commissions) exceeds the total amount of any damages which such holder of Registrable Securities has otherwise been required to pay by reason of a Violation by such Holder. 

 

 30 

 15C. Indemnification Procedures. Any Person entitled to indemnification
hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to
indemnification hereunder to the extent such failure has not adversely affected the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to
any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between
such indemnified party and any other of such indemnified parties with respect to such claim. 
 15D. Contribution.
If the indemnification provided for in this Section 15 is held by a court of competent jurisdiction to be unavailable (other than pursuant to its terms) to an indemnified party with respect to any loss, liability, claim, damage or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in
such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage
or expense as well as any other relevant equitable considerations; provided, that in no event shall any contribution by the holder of Registrable Securities under this Section 15 exceed the amount by which the total price at which the
Registrable Securities of such holder of Registrable Securities were offered to the public (less underwriters’ discounts and commissions) exceeds the total amount of any damages which such holder of Registrable Securities has otherwise been
required to pay by reason of a Violation by such Holder. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material
fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such
statement or omission. 
 15E. Other Indemnification Provisions. The obligations of the Company and the holders of
Registrable Securities under this Section 15 shall survive the completion of any offering of Registrable Securities in a registration statement under this Agreement, and otherwise. The indemnification provided for under this Agreement will
remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of securities. 

 

 31
