Securities, and in consideration of the acceptance of said Securities by the Holders thereof and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

 ARTICLE 1 
 DEFINITIONS 
 (a) Capitalized terms used herein and not otherwise defined herein shall have the respective meanings
ascribed thereto in the Base Indenture. 
 (b) The rules of interpretation set forth in the Base Indenture shall be applied hereto as if set
forth in full herein. 

 (c) For all purposes of this Fifth Supplemental Indenture, except as otherwise expressly provided or
unless the context otherwise requires, the following terms shall have the following respective meanings (such meanings shall apply equally to both the singular and plural forms of the respective terms). 
 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date for the Notes, the
average of four Reference Treasury Dealer Quotations obtained by the Trustee for that applicable Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or, if the Trustee obtains fewer than four
Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Trustee. 
 “Guarantors” means, initially, American Overseas Marine Corporation, a Delaware corporation, Bath Iron Works Corporation, a Maine corporation, Electric Boat Corporation, a Delaware corporation, General Dynamics Armament and
Technical Products, Inc., a Delaware corporation, General Dynamics Government Systems Corporation, a Delaware corporation, General Dynamics Land Systems Inc., a Delaware corporation, General Dynamics Ordnance and Tactical Systems, Inc., a Virginia
corporation, Gulfstream Aerospace Corporation, a Delaware corporation, and National Steel and Shipbuilding Company, a Nevada corporation. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers, to be appointed by the Company. 
 “Notes” shall have the meaning ascribed thereto in Section 2.01(a) hereof. 
 “Reference Treasury
Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding the Redemption Date. 
 “Reference Treasury Dealer” means each of Banc of America Securities LLC, J.P. Morgan Securities Inc. and RBS Securities Inc. (so long
as they continue to be primary U.S. Government securities dealers) and any one other primary U.S. Government securities dealer chosen by the Company, and their respective successors. If Banc of America Securities LLC, J.P. Morgan Securities Inc. or
RBS Securities Inc. ceases to be a primary U.S. Government securities dealer, the Company will appoint in its place another nationally recognized investment banking firm that is a primary U.S. Government securities dealer. 
  

 2 

 “Remaining Scheduled Payments” means, with respect to each Note that the Company is
redeeming, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date if such Note were not redeemed. However, if the Redemption Date is not a scheduled interest payment date
with respect to that Note, the amount of the next succeeding scheduled interest payment on that Note will be deemed to be reduced by the amount of interest accrued on such Note to the Redemption Date. 
 “Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of
the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date. The Treasury Rate will be calculated on
and as of the third Business Day immediately preceding the Redemption Date.

 (FORM OF REVERSE OF NOTE DUE 2011) 
 This Note is one of a duly authorized series of Notes of the Company (herein sometimes referred to as the “Notes”), all issued or to be
issued under and pursuant to an Indenture dated as of August 27, 2001, duly executed and delivered by and among the Company, the Guarantors named therein and The Bank of New York Mellon, as trustee (the “Trustee”), as
supplemented to date, including by the Fifth Supplemental Indenture dated as of June 24, 2009, by and among the Company, the Guarantors named therein and the Trustee (the Indenture, as so supplemented, the “Indenture”), to
which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Guarantors named therein and the
Holders of the Notes. By the terms of the Indenture, the Notes are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture. This series of Notes is initially offered in
aggregate principal amount as specified in said Fifth Supplemental Indenture. 
 The Company at its option may, at any time and from time to
time, redeem the Notes, in whole or in part, upon payment of a redemption price equal to (A) the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) the sum of the present values of the Remaining Scheduled
Payments discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at the Treasury Rate plus 12.5 basis points plus (B) accrued and unpaid interest, if any, on the principal amount
of Notes being redeemed to but excluding the Redemption Date (the “Redemption Price”). On and after the Redemption Date, interest will cease to accrue on the Notes or any portion thereof called for redemption, unless the Company
defaults in the payment of the Redemption Price and accrued interest. 
 Any redemption pursuant to the preceding paragraph will be made upon
not less than 30 nor more than 60 days’ prior notice before the Redemption Date to the Holders, at the Redemption Price. If the Notes are only partially redeemed, the Notes to be redeemed shall be selected by the Trustee by such method as the
Trustee shall deem fair and appropriate; provided, that if at the time of redemption the Notes are registered as Global Securities, the Depository shall determine, in accordance with its procedures, the principal amount of such Notes held by each
Holder of Notes to be redeemed. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the Redemption Date or such earlier time as the Company determines, provided that the Company shall deposit with the Trustee an amount
sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price is to be paid. 
 In the event of
redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
  

 9 

 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the
principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate
principal amount of the Notes of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions
of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that no such supplemental indenture shall, among other things, (i) change the fixed maturity of any Notes
of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without the consent of the Holder of each Note so affected, or
(ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then outstanding and affected thereby. The Indenture also contains
provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time outstanding affected thereby, on behalf of all of the Holders of the Notes of such series, to waive any past default in the
performance of any of the covenants contained in the indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the principal of or premium, if any, or interest on any of
the Notes of such series. Any such consent or waiver by the registered Holder (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and of any Note issued
in exchange therefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, this Note is transferable by the registered Holder hereof on the
Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Trustee in the City and State of New York accompanied by a written instrument or instruments of transfer in form satisfactory
to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service 

  

 10 

 
charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in
relation thereto. 
 Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any paying agent and the
Security Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security
Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security Registrar
shall be affected by any notice to the contrary. 
 No recourse shall be had for the payment of the principal of, premium, if any, or the
interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or any
Guarantor or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part
of the consideration for the issuance hereof, expressly waived and released. 
 The Notes of this series are issuable only in registered form
without coupons in denominations of $2,000 and any integral multiple of $1,000 above that amount. This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the
Indenture and subject to certain limitations herein and therein set forth, Notes of this series so issued are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the
Holder surrendering the same. 
 All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in
the Indenture. 
 THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS NOTE WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

 Exhibit 10.1 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement (“Agreement”) is made as
of March 1, 2009 by and between ResMed Inc., a Delaware corporation (the “Company”), and                     
(“Indemnitee”). This Agreement supersedes and replaces any and all previous Agreements between the Company and Indemnitee covering the subject matter of this Agreement. 
 RECITALS 
 WHEREAS, highly competent persons have become more reluctant to serve
publicly-held corporations as directors, officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their
service to and activities on behalf of the corporation; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has
determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain
liabilities. Although the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such
insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to
expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The By-laws of the Company require indemnification of the officers
and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”). The By-laws and the DGCL expressly provide that the indemnification provisions
set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification; 
 WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons;

 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best
interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of,
such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

 WHEREAS, this Agreement is a supplement to and in furtherance of the By-laws of the Company and any
resolutions adopted pursuant thereto, and will not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 
 WHEREAS, Indemnitee does not regard the protection available under the Company’s By-laws and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director 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 on the condition that he be so indemnified; and

 NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and
agree as follows: 
 Section 1. Services to the Company. Indemnitee agrees to serve as a director, officer, employee, or agent of
the Company, or, at the request of the Company, as a director, officer, employee, agent, or fiduciary of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise. Indemnitee may at any time and for any
reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in which event the Company will have no obligation under this Agreement to continue Indemnitee in such position. This
Agreement will not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s employment with the Company (or any of its
subsidiaries or any Enterprise), if any, is at will, and the Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any written employment contract between Indemnitee and the Company
(or any of its subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect to service as a director or officer of the Company, by the Company’s Certificate of Incorporation, the
Company’s By-laws, and the DGCL. The foregoing notwithstanding, this Agreement will continue in force after Indemnitee has ceased to serve as an officer, director, agent, or employee of the Company. 
 Section 2. Definitions. As used in this Agreement: 
 (a) References to “agent” will mean any person who is or was a director, officer, or employee of the Company or a Subsidiary of the Company or other person authorized by the Company to act for the Company,
to include such person serving in such capacity as a director, officer, employee, fiduciary or other official of another corporation, partnership, limited liability company, joint venture, trust or other Enterprise at the request of, for the
convenience of, or to represent the interests of the Company or a Subsidiary of the Company.

 (b) A “Change in Control” will be deemed to occur upon the earliest to occur after the date of
this Agreement of any of the following events: 
 i. a transaction or series of transactions whereby any “person” or related
“group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of the
Company possessing more than 50% of the total combined voting power of the Company’s securities outstanding immediately after such acquisition, other than: 
 ii. an acquisition by an employee benefit plan or any trustee holding securities under any employee benefit plan (or related trust) sponsored or maintained by the Company or any person controlled by the Company; or

 iii. an acquisition by the Company or a “person” that, prior to such transaction, directly or indirectly controls, is
controlled by, or is under common control with, the Company; or 
 iv. an acquisition pursuant to the offering of shares of Common Stock by
the Company to the general public through a registration statement filed with the Securities and Exchange Commission; or 
 v. an
acquisition of voting securities pursuant to a transaction described in clause (vii) below that would not be a Change of Control under clause (viii). 
 vi. individuals who, as of the date hereof, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any
individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Company’s stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be
considered to be members of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office was a result of an actual or threatened election contest with respect to the election or removal of directors;
or 
 vii. The consummation by the Company (whether directly involving the Company or indirectly involving the Company through one or more
intermediaries) of (x) a merger, consolidation, reorganization, or business combination or (y) a sale or other disposition of all or substantially all of the Company’s assets in any single transaction or series of related transactions
or (z) the acquisition of assets or stock of another entity, in each case other than a transaction: 
 1 which results in the
Company’s voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the Successor Entity) directly or indirectly, at least a
majority of the combined voting power of the Successor Entity’s outstanding voting securities immediately after the transaction; or 
  

 -3- 

 2 after which more than 50% of the members of the board of directors of the Successor Entity were
members of the Incumbent Board at the time of the Board’s approval of the transaction or the agreement providing for the transaction. 
 viii. The Company’s stockholders approve a liquidation or dissolution of the Company. 
 ix. For purposes of subsection
(i) above, the calculation of voting power shall be made as if the date of the acquisition were a record date for a vote of the Company’s stockholders, and for purposes of subsection (iii) above, the calculation of voting power shall
be made as if the date of the consummation of the transaction or at the consummation of the last of a series of related transactions were a record date for a vote of the Company’s stockholders. For purposes of subsection
(iii) “Successor Entity” means the Company or the “person” that, as a result of the transaction, controls, directly or indirectly, the Company or owns, directly or indirectly, all or substantially all of the
Company’s assets or otherwise succeeds to the business of the Company. 
 (c) “Corporate Status” describes the status of a
person who is or was a director, officer, employee or agent of the Company or of any other corporation, limited liability company, partnership or joint venture, trust, employee benefit plan or other enterprise which such person is or was serving at
the request of the Company. 
 (d) “Disinterested Director” means a director of the Company who is not and was not a party to the
Proceeding in respect of which indemnification is sought by Indemnitee. 
 (e) “Enterprise” will mean the Company and any other
corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary.

 (f) “Expenses” will include all reasonable attorneys’ fees, retainers, court costs, transcript costs, fees of experts,
witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, any federal, state, local or foreign taxes imposed on Indemnitee as a result of the actual or deemed receipt of any
payments under this Agreement, ERISA excise taxes and penalties, and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing
to be a witness in, or otherwise 

  

 -4- 

 
participating in, a Proceeding. Expenses also will include (i) Expenses 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, and (ii) for purposes of Section 14(d) only, Expenses incurred by Indemnitee in connection
with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement, by litigation or otherwise. The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written demand to the
Company in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable will be presumed conclusively to be reasonable. Expenses, however, will not include
amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee. 
 (g) “Independent Counsel” means
a law firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such
party (other than with respect to matters concerning the Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification
hereunder. Notwithstanding the foregoing, the term “Independent Counsel” will 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. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any
and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 
 (h) The
term “Proceeding” will include any threatened, pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding,
whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative legislative, or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a
party, potential party, non-party witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the Company, by reason of any action taken by him or of any action on his part while acting as director or officer of the
Company, or by reason of the fact that he is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, limited liability company, partnership, joint venture, trust or other enterprise, in each
case whether or not serving in such capacity at the time any liability or expense is incurred for which indemnification, reimbursement, or advancement of expenses can be provided under this Agreement. If the Indemnitee believes in good faith that a
given situation may lead to or culminate in the institution of a Proceeding, this will be considered a Proceeding under this paragraph. 
  

 -5- 

 (i) Reference to “other enterprise” will include employee benefit plans; references to
“fines” will include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” will include any service as a director, officer, employee or agent of the Company which
imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in
the best interests of the participants and beneficiaries of an employee benefit plan will be deemed to have acted in manner “not opposed to the best interests of the Company” as referred to in this Agreement. 
 Section 3. Indemnity in Third-Party Proceedings. The Company will 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 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
will be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his behalf in connection with such Proceeding or any
claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he 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
his conduct was unlawful. The parties hereto intend that this Agreement will provide to the fullest extent permitted by law for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification
provided by the Company’s Certificate of Incorporation, its Bylaws, vote of its stockholders or disinterested directors or applicable law. 
 Section 4. Indemnity in Proceedings by or in the Right of the Company. The Company will 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 in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 4, Indemnitee will be indemnified to the fullest extent permitted by applicable law against all Expenses actually and
reasonably incurred by him or on his behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the
Company. No indemnification for Expenses will be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee will have been finally adjudged by a court to be liable to the Company, unless and only to the extent
that the Delaware Court of Chancery or any court in which the Proceeding was brought will 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. 
  

 -6- 

 Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provisions of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in
defense of any claim, issue or matter therein, in whole or in part, the Company will 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 will indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in
connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by law. 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, will be deemed to be a successful result as to such claim, issue or matter. 
 Section 6.
Indemnification For Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of his Corporate Status, a witness or
otherwise asked to participate in any Proceeding to which Indemnitee is not a party, he will be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 
 Section 7. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for
some or a portion of Expenses, but not, however, for the total amount thereof, the Company will nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 
 Section 8. Additional Indemnification. 
 (a) Notwithstanding any limitation in Sections 3, 4, or 5, the Company will indemnify Indemnitee to the fullest extent permitted by applicable 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. 
  

 -7- 

 (b) For purposes of Section 8(a), the meaning of the phrase “to the fullest extent permitted by
applicable law” will include, but not be limited to: 
 i. 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 
 ii. 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 and directors.

 Section 9. Exclusions. Notwithstanding any provision in this Agreement, the Company will not be obligated under this Agreement
to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made to or on behalf
of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 
 (b) for (i) 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 (as defined in Section 2(b) hereof) or similar provisions of state statutory law or common law, or (ii) any reimbursement of the Company by the Indemnitee of any bonus or other
incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting
restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of
Section 306 of the Sarbanes-Oxley Act); or 
 (c) except as provided in Section 14(d) of this Agreement, 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) the
Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 
 Section 10. Advances of Expenses. Notwithstanding any provision of this Agreement to the contrary, the Company will advance, to the extent
not prohibited by law, the Expenses incurred by Indemnitee in connection with any Proceeding, and such advancement will be made 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. Advances will be unsecured and interest free. Advances will be made without regard to Indemnitee’s ability to repay the Expenses and without regard to
Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. Advances will include any and all reasonable Expenses 

  

 -8- 

 
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. The Indemnitee will qualify for advances upon the execution and delivery to the Company of this Agreement, which will constitute an undertaking providing that the Indemnitee undertakes to repay the amounts advanced (without
interest) to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. No other form of undertaking will be required other than the execution of this Agreement. This Section 10 will not apply
to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 9. 
 Section 11. Procedure for Notification
and Defense of Claim. 
 (a) Indemnitee will notify the Company in writing of any matter with respect to which Indemnitee intends to seek
indemnification or advancement of Expenses hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. The written notification to the Company will include a description of the nature of the Proceeding
and the facts underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee will submit to the Company a written request, 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 following the final disposition of such action, suit or proceeding. The omission by Indemnitee to notify the Company hereunder
will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay in so notifying the Company will not constitute a waiver by Indemnitee of any rights under this
Agreement. The Secretary of the Company will, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 
 (b) The Company will be entitled to participate in the Proceeding at its own expense. 
 Section 12. Procedure Upon Application for Indemnification. 
 (a) Upon written request by Indemnitee for indemnification pursuant to the Section 11(a), a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto will be made in the
specific case: (i) if a Change in Control will have occurred, by Independent Counsel in a written opinion to the Board, a copy of which will be delivered to Indemnitee; or (ii) if a Change in Control will not have occurred, (A) by a
majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board,
(C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which will be delivered to Indemnitee or (D) if so directed by the 

  

 -9- 

 
Board, by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee will be made
within ten (10) days after such determination. Indemnitee will 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 person, persons or entity making such determination will be borne by the Company (irrespective of the determination as to Indemnitee’s
entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 
 (b) In the event the
determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) hereof, the Independent Counsel will be selected as provided in this Section 12(b). If a Change in Control will not have
occurred, the Independent Counsel will be selected by the Board, and the Company will give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If a Change in Control will have occurred, the Independent
Counsel will be selected by Indemnitee (unless Indemnitee will request that such selection be made by the Board, in which event the preceding sentence will apply), and Indemnitee will give written notice to the Company advising it of the identity of
the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection will have been given, deliver to the Company or to Indemnitee, as the case may
be, 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 will set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected will act as Independent Counsel. If such 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 has determined that such objection is without merit. If, within twenty (20) days after
the later of submission by Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition of the Proceeding, no Independent Counsel will 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 will have been made by the Company or Indemnitee to the other’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 will designate, and the person with respect to whom all objections are so resolved or the person so appointed will act as Independent Counsel under Section 12(a)
hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel will be discharged and relieved of any further responsibility in such capacity (subject to the applicable
standards of professional conduct then prevailing). 
  

 -10- 

 Section 13. Presumptions and Effect of Certain Proceedings. 
 (a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination will, to
the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(a) of this Agreement, and the Company
will, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the
Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action 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 its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct, will be a defense to the action or create a
presumption that Indemnitee has not met the applicable standard of conduct. 
 (b) Subject to Section 14(e), if the person, persons or
entity empowered or selected under Section 12 of this Agreement to determine whether Indemnitee is entitled to indemnification will not have made a determination within sixty (60) days after receipt by the Company of the request therefor,
the requisite determination of entitlement to indemnification will, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee will 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 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; and provided, further, that the foregoing provisions of this Section 13(b) will not apply (i) if the determination of
entitlement to indemnification is to be made by the stockholders pursuant to Section 12(a) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the Board has resolved
to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of
stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made
thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) of this Agreement. 
  

 -11- 

 (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, will 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 he 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 his conduct was unlawful. 
 (d) Reliance as Safe Harbor. For purposes of any determination of good faith, Indemnitee
will be deemed to have acted in good faith if Indemnitee’s action 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 with the
reasonable care by the Enterprise. The provisions of this Section 13(d) will not be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed 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 director, officer, agent or
employee of the Enterprise will not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 
 Section 14. Remedies of Indemnitee. 
 (a) Subject to Section 14(e), in the event that (i) a determination is
made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 10 of this Agreement, (iii) no
determination of entitlement to indemnification will have been made pursuant to Section 12(a) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification
is not made pursuant to Section 5, 6 or 7 or the last sentence of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to
Section 3, 4 or 8 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any other person takes or threatens to
take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the Indemnitee the 

  

 -12- 

 
benefits provided or intended to be provided to the Indemnitee hereunder, Indemnitee will be entitled to an adjudication by a court of his entitlement to
such indemnification or advancement of Expenses. Alternatively, Indemnitee, at his 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.
Indemnitee will commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 14(a); provided,
however, that the foregoing clause will not apply in respect of a proceeding brought by Indemnitee to enforce his rights under Section 5 of this Agreement. The Company will not oppose Indemnitee’s right to seek any such adjudication
or award in arbitration. 
 (b) In the event that a determination will have been made pursuant to Section 12(a) of this Agreement that
Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 will be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee will
not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 14 the Company will have the burden of proving Indemnitee is not entitled to indemnification or advancement
of Expenses, as the case may be. 
 (c) If a determination will have been made pursuant to Section 12(a) of this Agreement that
Indemnitee is entitled to indemnification, the Company will be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14, 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) The Company will, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced
pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and will stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this
Agreement. It is the intent of the Company that, to the fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights
under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company will, to the fullest extent permitted by law,
indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, will (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by law, such Expenses to Indemnitee,
which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any 

  

 -13- 

 
directors’ and officers’ liability insurance policies maintained by the Company if Indemnitee is wholly successful on the underlying claims; if
Indemnittee is not wholly successful on the underlying claims, then such indemnification and advancement will be only to the extent Indemnitee is successful on such underlying claims or otherwise as permitted by law, whichever is greater.

 (e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under
this Agreement will be required to be made prior to the final disposition of the Proceeding. 
 Section 15. Non-exclusivity; Survival
of Rights; Insurance; Subrogation. 
 (a) The rights of indemnification and to receive advancement of Expenses as provided by this
Agreement will not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Company’s Certificate of Incorporation, the Company’s By-laws, 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 will limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee
in his 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 By-laws and this Agreement, it is the intent of the parties hereto that Indemnitee will 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 will 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, will 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, officers, employees, or agents of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise which such person serves at the request of the Company, Indemnitee will be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee
or agent under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company will give prompt notice of such claim or of
the commencement of a proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the respective policies. The Company will thereafter take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 
  

 -14- 

 (c) In the event of any payment under this Agreement, the Company will be subrogated to the extent of
such payment to all of the rights of recovery of Indemnitee, who will execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to
enforce such rights. 
 (d) The Company will not be liable under this Agreement to make any payment of amounts otherwise indemnifiable (or
for which advancement is provided hereunder) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 
 (e) The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a
director, officer, employee or agent of any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise will be reduced by any amount Indemnitee has actually received as indemnification
or advancement of Expenses from such other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise. 
 Section 16. Duration of Agreement. This Agreement will continue until and terminate upon the later of: (a) ten (10) years after the date that Indemnitee will have ceased to serve as a director,
officer, employee, or agent of the Company, or at the request of the Company, as a director, officer, employee, agent, or fiduciary of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, or
(b) one (1) year after the final termination of any Proceeding then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to
Section 14 of this Agreement relating thereto. This Agreement will be binding upon the Company and its successors and assigns and will inure to the benefit of Indemnitee and his heirs, executors and administrators. 
 Section 17. Severability. If any provision or provisions of this Agreement will be held to be invalid, illegal or unenforceable for any
reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid,
illegal or unenforceable, that is not itself invalid, illegal or unenforceable) will not in any way be affected or impaired thereby and will remain enforceable to the fullest extent permitted by law; (b) such provision or provisions will be
deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation,
each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) will be construed so as to give effect to the intent manifested thereby.

 Section 18. Enforcement. 
 (a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce
Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the Company. 
 (b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior
agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation of the
Company, the By-laws of the Company and applicable law, and will not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 
 Section 19. Modification and Waiver. No supplement, modification or amendment of this Agreement will be binding unless executed in writing by the parties thereto. No waiver of any of the provisions of this
Agreement will be deemed or will constitute a waiver of any other provisions of this Agreement nor will any waiver constitute a continuing waiver. 
 Section 20. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any
Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company will not relieve the Company of any obligation which it may have to the Indemnitee under
this Agreement or otherwise. 
 Section 21. Notices. All notices, requests, demands and other communications under this
Agreement will be in writing and will be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication will have been directed, (b) mailed by certified or registered mail
with postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication will have been directed or
(d) sent by facsimile transmission, with receipt of oral confirmation that such transmission has been received:

settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect
