 Exhibit 4.3 

FIRST SUPPLEMENTAL INDENTURE 

FIRST SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of April 12, 2010, between Ryerson Holding
Corporation, a Delaware corporation (the “Company”), and Wells Fargo Bank, N.A., as trustee (the “Trustee”), under the Indenture (as defined and referred to below). All capitalized terms used but not otherwise
defined herein shall have the meaning assigned thereto in the Indenture. 
 W I T N E S E T H : 

WHEREAS, the Company and the Trustee have entered into an Indenture, dated as of January 29, 2010 (the
“Indenture”), providing for the issuance of the Company’s 14.5% Senior Discount Notes Due 2015; 

WHEREAS, on March 30, 2010, representatives of each of the Company and the Initial Purchasers convened a telephonic meeting to
discuss Section 4.22 of the Indenture and whether it was the intent of the parties to use Excess Qualified Equity Issuance Proceeds to make an Offer to Purchase to all holders of Ryerson Notes or whether such provision was intended to require
that an Offer to Purchase be made solely to holders of Ryerson’s 12% Senior Secured Notes due 2015; 
 WHEREAS, during such
telephonic meeting, representatives of each of the Company and the Initial Purchasers agreed that the intent of Section 4.22 of the Indenture was to require that any Offer to Purchase made with Excess Qualified Equity Issuance Proceeds pursuant
to Section 4.22 of the Indenture be made solely to holders of Ryerson’s 12% Senior Secured Notes due 2015 and not to all holders of Ryerson Notes and that anything in Section 4.22 of the Indenture to the contrary was a mistake;

 WHEREAS, Section 9.1(8) of the Indenture provides that the Company and the Trustee may, at any time and from time to
time, supplement the Indenture in order to cure any ambiguity, defect, omission, mistake or inconsistency without the consent of the Holders of the Notes; 

WHEREAS, the Board of Directors of the Company has determined in good faith that amendments contained herein shall not adversely affect
the interests of the Holders in any material respect; and 
 WHEREAS, all acts and things prescribed by the Indenture, by law
and by the charter and the bylaws (or comparable constituent documents) of the Company and the Trustee have been done to make this Supplemental Indenture a valid and binding agreement of the Company and the Trustee, in accordance with its terms.

 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders as follows: 
 1.
Ratification of Indenture; Supplemental Indentures Part of Indenture. Except as expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force
and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every holder of Securities heretofore or hereafter authenticated and delivered shall be bound hereby. 

2. Amendment to Indenture. The third paragraph of Section 4.22 of the Indenture is hereby amended and restated as follows:

 “In addition, the Company will, and will cause its Restricted Subsidiaries (including Ryerson) to, use an amount equal
to (x) 50% of any remaining Qualified Equity Issuance Net Proceeds that are not applied in accordance with the terms set forth above, less (y) any amounts previously paid by Ryerson to repurchase Ryerson’s 12% Senior Secured Notes due
2015 pursuant to the “equity claw” provision set forth in Section 3.7(a)(iii) of the Ryerson Indenture (as in effect on the Issue Date) (such amount, “Excess Qualified Equity Issuance Proceeds”) to make an Offer to
Purchase to all holders of Ryerson’s 12% Senior Secured Notes due 2015 equal to the Excess Qualified Equity Issuance Proceeds. Any such Offer to Purchase shall be made in accordance with the terms of the 

 Ryerson Indenture. The offer price in any such Offer to Purchase will be equal to 100% of the principal
amount thereof, plus accrued and unpaid Additional Interest, if any. If any Excess Qualified Equity Issuance Proceeds remain outstanding after consummation of any such Offer to Purchase, the Company may use the Excess Qualified Equity Issuance
Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Ryerson’s 12% Senior Secured Notes due 2015 tendered into such Offer to Purchase exceeds the amount of the Excess Proceeds, the trustee
under the Ryerson Indenture will select the Ryerson 12% Senior Secured Notes due 2015 to be purchased on a pro rata basis. Upon the completion of each Offer to Purchase, the amount of Excess Qualified Equity Issuance Proceeds will be reset at
zero.” 
 3. Opinion of Counsel. Concurrently with the execution and delivery of this Supplemental Indenture, the
Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate in accordance with the terms set forth in Sections 9.6, 13.4 and 13.5 of the Indenture. 

4. Successors. All agreements of the Company in this Supplemental Indenture shall bind its successors. All agreements of the
Trustee in this Supplemental Indenture shall bind its successors. 
 5. Governing Law. THE LAW OF THE STATE OF NEW
YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE. The parties to this Supplemental Indenture each hereby irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of
Manhattan in The City of New York in any action or proceeding arising out of or relating to the Notes or this Supplemental Indenture, and all such parties hereby irrevocably agree that all claims in respect of such action or proceeding may be heard
and determined in such New York State or federal court and hereby irrevocably waive, to the fullest extent that they may legally do so, the defense of an inconvenient forum to the maintenance of such action or proceeding. EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS SUPPLEMENTAL INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED
HEREBY. 
 6. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed
copy (including any facsimile) shall be an original, but all of them together represent the same agreement. 
 7. Effect of
Headings. The Section headings herein are for convenience only and shall not effect the construction thereof. 
 8.
Trustee. The Trustee makes no representations as to the validity or sufficiency of this Supplemental Indenture. The recitals and statements herein are deemed to be those of the Company and not of the Trustee. 

9. Severability. In case any provision in this Supplemental Indenture shall be invalid, illegal or unenforceable, the validity,
legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 10. Trust
Indenture Act Controls. If any provision of this Supplemental Indenture limits, qualifies or conflicts with another provision that is required to be included in this Supplemental Indenture or the Indenture by the Trust Indenture Act of 1939, as
amended, as in force at the date that this Supplemental Indenture is executed, the provisions required by said Act shall control.

CERTAIN RESTRICTIONS ON TRANSFERS 

Section 2.1 Transfers in Accordance with this Agreement. No Stockholder (other than members of the Platinum Group) shall,
directly or indirectly, transfer, sell, assign, pledge, hypothecate, encumber, or otherwise dispose of, all or any portion of any Shares or any economic interest therein (including without limitation by means of any participation or swap
transaction) (each, a “Transfer”) to any Person, except (A) transfers made in compliance with Sections 2.4 or 2.5 of this Agreement, and (B) with the prior written consent of Platinum Equity Advisors, LLC, which consent
may be withheld in its sole discretion. Any attempt to Transfer any Shares in violation of the terms of this Agreement shall be null and void, and neither the Company nor any transfer agent shall register upon its books any Transfer of Shares by a
Stockholder to any Person except a Transfer in accordance with this Agreement. 
 Section 2.2 Agreement to be Bound.
No Transfer of Shares by a Stockholder other than a member of the Platinum Group (other than Transfers in a Public Offering or pursuant to Rule 144 or any similar provisions then in force under the Securities Act) shall be effective unless
(i) the Transferee, if not already a party hereto, shall have executed and delivered to each other party hereto, as a condition precedent to such Transfer, an instrument reasonably satisfactory to such parties confirming that the Transferee
agrees to be bound by the terms of this Agreement with respect to the Shares so Transferred to the same extent applicable to the Transferor thereof, whereupon such Transferee shall be deemed a Stockholder hereunder, and (ii) the Transferee has
delivered to the Company an opinion of counsel reasonably satisfactory to the Company indicating that the proposed Transfer is exempt from applicable securities laws. 

Section 2.3 Share Certificates. 

(a) Each certificate representing Shares held by a Stockholder other than a member of the Platinum Group will bear a
legend on the face thereof substantially to the following effect (with such additions thereto or changes therein as the Company may be advised by counsel are required by law or necessary to give full effect to this Agreement): 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE STOCKHOLDERS’ AGREEMENT AMONG RHOMBUS HOLDING CORPORATION AND THE OTHER
STOCKHOLDERS PARTY THERETO, DATED AS OF DECEMBER 31, 2007, AS AMENDED AND SUPPLEMENTED FROM TIME TO TIME IN ACCORDANCE WITH THE TERMS THEREOF, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF RHOMBUS HOLDING CORPORATION. THE STOCKHOLDERS’
AGREEMENT CONTAINS, AMONG OTHER THINGS, CERTAIN PROVISIONS RELATING TO THE VOTING AND TRANSFER OF THE SHARES SUBJECT TO THE AGREEMENT. NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS
CERTIFICATE, DIRECTLY OR INDIRECTLY, MAY BE MADE EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH STOCKHOLDERS’ AGREEMENT. THE HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF SUCH
STOCKHOLDERS’ AGREEMENT. 
  

 5 

 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 OR ANY STATE SECURITIES ACTS AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY HAVE BEEN REGISTERED UNDER SUCH ACTS OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE. 

Section 2.4 Drag-Along Right. If at any time members of the Platinum Group propose to sell or cause the sale of a majority of
the outstanding Shares beneficially owned by the Platinum Group to a Third Party in any arm’s-length transaction or series of related transactions, then Platinum shall have the right to deliver a written notice (a “Buyout
Notice”) to each Stockholder which shall state (i) that Platinum (or the applicable parties) proposes to effect such transaction, (ii) the identity of the Third Party and the proposed purchase price per Share to be paid and any
other material terms and conditions, and (iii) the projected closing date of such sale. Each Stockholder agrees that, upon receipt of a Buyout Notice, such Stockholder shall be obligated to sell in such transaction the same percentage of the
Shares held by such Stockholder as the Platinum Group proposes to sell upon the terms and conditions of such transaction (and otherwise take all necessary action to cause consummation of the proposed transaction); provided, that in no event
shall such Stockholder be required to make any representations or provide any indemnities other than (A) on a proportionate basis, or (B) with respect to matters relating solely to such Stockholder, such as representations as to title to
Shares to be transferred by such Stockholder, and no Stockholder shall be obligated in connection with such Transfer to agree to indemnify or hold harmless the transferee with respect to an amount in excess of the sum of the net cash and value of
other proceeds paid to such Stockholder in connection with such Transfer. In the event that any such Transfer is structured as a merger, consolidation or similar business combination, each such Stockholder hereby agrees to vote in favor of the
transaction (including acting by written consent if requested) and take all action to waive any dissenter’s, appraisal or other similar rights such Stockholder may have. 

Section 2.5 Bring-Along Right. 

(a) Any member of the Platinum Group may Transfer its Shares in its sole discretion; provided, that it shall comply
with the provisions of this Section 2.5 in connection with any such Transfer other than: (i) to any Affiliate, any general or limited partner, member, director, officer or employee of such member of the Platinum Group (or their Permitted
Transferees within the meaning of clause (a) of the definition thereof), (ii) to the heirs, executors, administrators, testamentary trustees, legatees or beneficiaries of such member of the Platinum Group (or their Permitted Transferees
within the meaning of clause (a) of the definition thereof), (iii) to a corporation or partnership, a majority of the equity of which is owned and controlled by such member of the Platinum Group or Permitted Transferees referred to in
clauses (i) or (ii); (iv) in a Public Offering or (v) pursuant to Rule 144 or any similar provisions then in force under the Securities Act. 

(b) At least 5 days prior to any Transfer of Shares by a member of the Platinum Group (unless notice has been given
pursuant to Section 3.1), it shall give notice to the Company and each other Stockholder, specifying in reasonable detail the number of Shares to be Transferred and the terms and conditions of the Transfer. Each other Stockholder may elect to
participate in the contemplated Transfer at the same price per share and on the same terms by delivering written notice to the member of the Platinum Group within two (2) days after delivery of such notice. If any Stockholder elects to
participate in such Transfer, such Stockholder shall 
  

 6 

 
be entitled, subject to the last sentence of this paragraph (b), to Transfer in the contemplated Transfer, at the same price and on the same terms as the member of the Platinum Group, a number of
Shares equal to the product of (i) the percentage of the total number of outstanding Shares owned by such Stockholder and (ii) the number of Shares proposed to be Transferred in the contemplated Transfer by members of the Platinum Group.
Platinum shall use its reasonable efforts to cause a prospective transferee to allow the participation of electing Stockholders; provided, that if such prospective transferee declines to allow the participation of electing Stockholders,
members of the Platinum Group may nonetheless proceed with a Transfer of Shares to such prospective transferee. 

(c) Each Stockholder Transferring Shares pursuant to this Section 2.5 shall pay its pro rata share (based on the
number of Shares to be sold) of the expenses incurred by the Stockholders in connection with such Transfer and shall be obligated to join on a pro rata basis (based on the number of Shares to be sold) in any representations, warranties,
indemnification provisions, escrow arrangements and other obligations that the Platinum Group agrees to provide in connection with such Transfer (other than any such obligations that relate specifically to another particular Stockholder such as
indemnification with respect to representations and warranties given by such other Stockholder regarding such other Stockholder’s title to and ownership of Shares); provided, that no Stockholder shall be obligated in connection with such
Transfer to agree to indemnify or hold harmless the transferee with respect to an amount in excess of the sum of the net cash and value of other proceeds paid to such Stockholder in connection with such Transfer. 

ARTICLE III 

REGISTRATION 

Section 3.1 Piggyback Registrations. 

(a) Right to Piggyback. If at any time (x) following the consummation of an Initial Public Offering or
(y) in connection with an Initial Public Offering if any member of the Platinum Group sells any of its shares as a part of such Initial Public Offering, the Company proposes to register any of its or its Affiliates’ Common Stock under the
Securities Act (other than a transaction described under Rule 145 of the Securities Act or pursuant to Form S-8 or its successor forms) and the registration form to be used may be used for the registration of the Stockholders’ Registrable
Securities (a “Piggyback Registration”), the Company shall give prompt written notice to the Stockholders of its intention to effect such a registration and will include in such registration the Shares of the Stockholders with
respect to which the Company has received written requests for inclusion therein within twenty (20) days after the receipt of the Company’s notice; provided, that until the third anniversary of the effective date of the registration
statement relating to the Initial Public Offering, Stockholders other than members of the Platinum Group may only exercise the rights under this Section 3.1 if members of the Platinum Group are participating in such registration. 

(b) Piggyback Expenses. The Registration Expenses of the Stockholders shall be paid by the Company in all Piggyback
Registrations; provided, however, that for the avoidance of doubt, each of the Stockholders shall bear its pro rata portion of any discounts and commissions with respect to shares of Registrable Securities sold by it in connection
therewith. 
  

 7 

 (c) Priority on Registrations. If a Piggyback Registration is an
underwritten 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 without adversely affecting the marketability of the offering, then the number of Shares available for registration shall be allocated among the Stockholders requesting to sell Registrable Securities in such offering pro rata based on the
relative number of Registrable Securities then held by such Stockholder; provided, that any such amount thereby allocated to any such Stockholder that exceeds such Stockholder’s request shall be reallocated among the remaining requesting
Stockholders in like manner. 
 Section 3.2 Lockup Agreements. If any registration hereunder shall be in connection
with an underwritten Public Offering, each Stockholder holding Registrable Securities agrees not to effect any sale or distribution of the securities being registered or of a similar security of the Company or any securities convertible into or
exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the 15 days prior to, and during (i) the 180-day period beginning on the consummation of the Initial Public Offering, unless
the investment banks or Underwriters managing the Public Offering otherwise agree, and (ii) the 90-day period beginning on, the effective date of any other Public Offering to be underwritten on a firm commitment basis (except as part of such
underwritten registration), unless the investment banks or Underwriters managing the public offering otherwise agree. 

Section 3.3 Registration Procedures. Whenever the Stockholders holding Registrable Securities request in accordance with
Section 3.1(a) that any Registrable Securities be registered, the Company will use its reasonable best efforts to effect the registration of such Registrable Securities in accordance with the intended method of disposition thereof as
quickly as practicable, and in connection with any such request: 
 (a) The Company will as expeditiously as
practicable prepare and file with the United States Securities and Exchange Commission (the “Commission”) a registration statement on any form for which the Company then qualifies and which counsel for the Company shall deem
appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof (it being understood that the Company shall use Form S-3 (or any
replacement form) if such form is then available), and use its best efforts to cause such filed registration statement to become effective. 

(b) The Company will prepare and file with the Commission such amendments and supplements to such registration statement
and the prospectus used in connection therewith as may be necessary to keep such registration statement effective 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 with the intended methods of disposition by the Selling Stockholder or Selling Stockholders thereof set forth in such registration statement. 

 

 8 

 (c) The Company will, prior to filing a registration statement or prospectus
or any amendment or supplement thereto, furnish to each Stockholder selling Registrable Securities pursuant to a registration statement under this Article III (each, a “Selling Stockholder”), counsel representing any Selling
Stockholders, and each Underwriter, if any, of the Registrable Securities covered by such registration statement copies of such registration statement as proposed to be filed, together with exhibits thereto, which documents will be subject to review
by the foregoing persons within five (5) business days after delivery, and thereafter furnish to such Selling Stockholder, counsel and Underwriter, if any, such number of copies of such registration statement, each amendment and supplement
thereto (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such Selling
Stockholder or Underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Selling Stockholder. 

(d) After the filing of the registration statement, the Company will promptly notify each Selling Stockholder covered by
such registration statement of any stop order issued or threatened by the Commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered. 

(e) The Company will use its reasonable best efforts to (i) register or qualify the Registrable Securities under such
other securities or blue sky laws of such jurisdictions in the United States and such other jurisdictions as any Selling Stockholder reasonably (in light of such Selling Stockholder’s intended plan of distribution) requests and (ii) cause
such Registrable Securities to be registered with or approved by such other governmental agencies or authorities in the United States as may be necessary by virtue of the business and operations of the Company and do any and all other acts and
things that may be reasonably necessary or advisable to enable such Selling Stockholder to consummate the disposition of the Registrable Securities owned by such Selling Stockholder; provided, that the Company will not be required to
(A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (e), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of
process in any such jurisdiction. 
 (f) The Company will immediately notify each Selling Stockholder of such
Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the occurrence of an event requiring the preparation 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 material fact required to be stated therein or necessary to make the statements
therein not misleading, and will promptly make available to each Selling Stockholder any such supplement or amendment. 

(g) The Company will enter into customary agreements (including, if applicable, an underwriting agreement in customary
form) and take such other actions as are reasonably required (including providing assistance in the preparation of road show materials and using its reasonable best efforts to make available the executive officers of the Company to participate in
road show presentations, in each case as is reasonable and customary at such time in similar plans of distribution of similar securities) in order to expedite or facilitate the 

 

 9 

 
disposition of such Registrable Securities in accordance with the intended plan of distribution of the Selling Stockholders. The Selling Stockholders may, at their option, require that any or all
of the representations, warranties and covenants of the Company or to or for the benefit of such Underwriters also be made to and for the benefit of such Selling Stockholders. 

(h) The Company will deliver promptly to each Selling Stockholder of such Registrable Securities and each Underwriter, if
any, subject to restrictions imposed by the United States federal government or any agency or instrumentality thereof, copies of all correspondence between the Commission and the Company its counsel or auditors and all memoranda relating to
discussions with the Commission or its staff with respect to the registration statement and make available for inspection by any Selling Stockholder of such Registrable Securities, any Underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other professional retained by any such Selling Stockholder or Underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and
properties of the Company (collectively, the “Records”), as shall be reasonably necessary to enable them to perform a reasonable and customary due diligence investigation, and cause the Company’s officers, directors and
employees to supply all information reasonably requested by any Inspectors in connection with such registration statement. Records which the Company determines, in good faith, to be confidential and which it notifies the Inspectors are confidential
shall not be disclosed by the Inspectors unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such registration statement or (ii) the disclosure or release of such Records is requested or
required pursuant to oral questions, interrogatories, requests for information or documents or a subpoena or other order from a court of competent jurisdiction or other process; provided, that prior to any disclosure or release pursuant to
clause (ii), the Inspectors shall provide the Company with prompt notice of any such request or requirement so that the Company may seek an appropriate protective order or waive such Inspectors’ obligation not to disclose such Records; and
provided, further, that if failing the entry of a protective order or the waiver by the Company permitting the disclosure or release of such Records, the Inspectors, upon advice of counsel, are compelled to disclose such Records, the
Inspectors may disclose that portion of the Records which counsel has advised the Inspectors that the Inspectors are compelled to disclose, Each Selling Stockholder of such Registrable Securities agrees that it will, upon learning that disclosure of
such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential. 

(i) The Company will furnish to each Selling Stockholder and to each Underwriter, if any, a signed counterpart, addressed
to such Selling Stockholder or Underwriter, of (i) an opinion or opinions of counsel to the Company and (ii) a comfort letter or comfort letters from the Company’s independent public accountants, each in customary form and covering
such matters of the type customarily covered by opinions or comfort letters, as the case may be, as the Selling Stockholders of Registrable Securities included in such offering or the managing Underwriter, if any, therefor reasonably requests.

 (j) The Company will use its reasonable best efforts to comply with all applicable rules and regulations of
the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering a period of 12 months, beginning within three months after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder. 
  

 10 

 (k) The Company will use its reasonable best efforts (a) to cause all
such Registrable Securities to be listed on a national securities exchange (if such shares are not already so listed) and on each additional national securities exchange on which similar securities issued by the Company are then listed (if any), if
the listing of such Registrable Securities is then permitted under the rules of such exchange or (b) to secure designation of all such Registrable Securities covered by such registration statement as a NASDAQ “national market system
security” within the meaning of Rule 11Aa2-l of the Commission or, failing that, to secure NASDAQ authorization for such Registrable Securities and, without limiting the generality of the foregoing, to arrange for at least two market makers to
register as such with respect to such Registrable Securities with the NASD. 
 (1) The Company will appoint a
transfer agent and registrar for all such Registrable Securities covered by such registration statement not later than the effective date of such registration statement. 

(m) The Company may require each Selling Stockholder of Registrable Securities to promptly furnish in writing to the
Company such information regarding the distribution of the Registrable Securities as the Company may from time to time reasonably request and such other information as may be legally required in connection with such registration. 

(n) Each Selling Stockholder agrees that, upon receipt of any notice from the Company of the happening of any event of the
kind described in Section 3.3(f), such Selling Stockholder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Selling Stockholder’s
receipt of the copies of the supplemented or amended prospectus contemplated by Section 3.3(f), and, if so directed by the Company, such Selling Stockholder will deliver to the Company all copies, other than permanent file copies then in such
Selling Stockholder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. In the event the Company shall give such notice, the Company shall extend the period during which such
registration statement shall be maintained effective (including the period referred to in Section 3.3(b)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 3.3(f) to the date
when the Company shall make available to the Selling Stockholders of Registrable Securities covered by such registration statement a prospectus supplemented or amended to conform with the requirements of Section 3.3(f). 

Section 3.4 Registration Expenses. All expenses incident to the Company’s performance of or compliance with this
Agreement, including 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 disbursements of counsel for the Company and all independent
certified public accountants, Underwriters (excluding discounts and commissions) and other Persons retained by the Company (all such expenses being herein called “Registration Expenses”) shall be borne as provided in this Agreement,
except that the Company shall, in any 
  

 11 

 
event, pay its internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review,
the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed or on the NASD automated quotation system.

 Section 3.5 Termination of Registration Rights. The registration rights provided by this Article III will
terminate with respect to each Stockholder (other than members of the Platinum Group) when such Stockholder owns less than 1.0% of the Company’s outstanding Common Stock and is able to sell all of its shares of Common Stock pursuant to Rule 144
of the Securities Act during any three-month period; provided, that such registration rights shall not terminate with respect to any Stockholder that holds less than 1.0% of the Company’s outstanding Common Stock if such Stockholder has
not at any time Transferred any shares of Common Stock acquired by it; and provided further that, for the purposes of this Section 3.5, (a) Assignor, Assignee and their respective Affiliates, collectively, shall be treated as
one Stockholder and (b) neither Assignor nor Assignee shall be deemed to have Transferred any shares of Common Stock solely due to any Transfer occurring solely between Assignor and Assignee. 

ARTICLE IV 

INDEMNIFICATION, CONTRIBUTION AND OTHER MATTERS 

Section 4.1 Indemnification by the Company. 

(a) To the fullest extent permitted by law, the Company agrees to indemnify and hold harmless each Selling Stockholder of
Registrable Securities, its officers, directors, employees and agents, and each Person, if any, who controls such Selling Stockholder within the meaning of the Securities Act from and against any loss, claim, damage or liability, joint or several,
or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Common Stock) to which such Selling Stockholder, officer, director, employee or agent or controlling
Person may become subject under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any
registration statement, prospectus or any preliminary prospectus or any amendment or supplement thereto relating to the Registrable Securities or (ii) any omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading and shall reimburse each Selling Stockholder and each such officer, director, employee, agent and controlling Person for any legal and other expenses reasonably incurred by that
Selling Stockholder, officer, director, employee, agent or controlling Person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred, except
insofar as the same are contained in any information furnished in writing to the Company by such Selling Stockholder expressly for use therein. The Company also agrees to indemnify any Underwriters of the Registrable Securities, their officers and
directors and each Person who controls such Underwriters on substantially the same basis as that of the indemnification of the Selling Stockholders provided in this Section 4.1(a). 

 

 12 

 (b) To the fullest extent permitted by law, the Company further agrees to
indemnify and hold harmless each Stockholder, its officers, directors, employees and agents, and each Person, if any, who controls such Stockholder within the meaning of the Securities Act from and against any loss, claim, damage or liability, joint
or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Common Stock) to which such Stockholder, officer, director, employee or agent or controlling
Person may become subject under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises with respect to any controlling shareholder or other vicarious liabilities with its ownership of capital stock of the
Company. 
 (c) The indemnities provided by this Section 4.1 shall remain in full force and effect
regardless of any investigation made by or on behalf of such Selling Stockholder or Underwriter. 
 Section 4.2
Indemnification by Stockholders of Registrable Securities. To the fullest extent permitted by law, each Selling Stockholder agrees, severally but not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and
each Person, if any, who controls the Company within the meaning of the Securities Act to the same extent as the indemnity from the Company to such Selling Stockholder pursuant to clauses (i) and (ii) of Section 4.1(a), but only with
reference to information related to such Selling Stockholder furnished in writing by such Selling Stockholder or on such Selling Stockholder’s behalf expressly for use in any registration statement or prospectus relating to the Registrable
Securities, or any amendment or supplement thereto, or any preliminary prospectus; provided, that the obligation to indemnify will be individual to each Selling Stockholder and will be limited to the total price at which the Registrable
Securities of such Selling Stockholder were offered and sold to the public (less underwriting discounts and commissions) pursuant to such registration statement. Each Selling Stockholder also agrees to indemnify and hold harmless Underwriters of the
Registrable Securities, their officers and directors and each Person who controls such Underwriters on substantially the same basis as that of the indemnification of the Company provided in this Section 4.2, subject to the proviso in the first
sentence of this Section 4.2. Notwithstanding the foregoing, the indemnity set forth in this Section 4.2 shall not apply to amounts paid in settlements effected without the consent of such Selling Stockholder (which consent shall not be
unreasonably withheld or delayed). 
 Section 4.3 Conduct of Indemnification Proceedings. Promptly after receipt by
any person in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2 (an “Indemnified Party”) of notice of any claim or the commencement of any action, the Indemnified Party shall, if a claim in respect thereof
is to be made against the Person against whom such indemnity may be sought (an “Indemnifying Party”), notify the Indemnifying Party in writing of the claim or the commencement of such action; provided, that the failure to
notify the Indemnifying Party shall not relieve it from any liability which it may have to an Indemnified Party under Sections 4.1 or 4.2, except to the extent of any actual prejudice resulting therefrom. If any such claim or action shall be brought
against an Indemnified Party, and it shall notify the Indemnifying Party thereof, the Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified Indemnifying Party, to
assume the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim

  

 13 

 
or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense
thereof other than reasonable costs of investigation; provided, that the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party and its controlling Persons who may be subject to liability arising
out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, but the fees and expenses of such counsel shall be for the account of such Indemnified Party unless (i) the Indemnifying Party
and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is
or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

 Section 4.4 Contribution. If the indemnification provided for in this Article IV is unavailable to the
Indemnified Parties in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages, liabilities or expenses as between the Company on the one hand and each Selling Stockholder on the other, in such proportion as is appropriate to reflect the relative fault of the
Company and of each Selling Stockholder in connection with such statements or omissions, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of each Selling Stockholder on the other shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

The Company and the Selling Stockholders agree that it would not be just and equitable if contribution pursuant to this
Section 4.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified
Party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no Selling Stockholder shall be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Securities of such Selling Stockholder were offered and sold to the public (less underwriting discounts and commissions) exceeds the amount of any damages which such Selling Stockholder has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. Each Selling Stockholder’s obligations to contribute pursuant to this Section 4.4 are several in proportion to the proceeds of the offering received by such Selling
Stockholder and not joint. 
  

 14

a member of the Platinum Group, each Person appointed or nominated to the Board as a director or observer (each, a “Board Participant”) and each Affiliated Officer has the right to, and shall have no duty (contractual or otherwise)
not to, directly or indirectly engage in the same or similar business activities or lines of business as the Company or any Subsidiary of the Company, including those deemed to be competing with the Company or any Subsidiary of the Company; and
(ii) in the event that a member of the Platinum Group, an Affiliate of a member of the Platinum Group, a Board Participant or an Affiliated Officer of the Company acquires knowledge of a potential transaction or matter that may be a corporate
opportunity for each of the Company and such member of the Platinum Group, Affiliate of a member of the Platinum Group, Board Participant, Affiliated Officer or any other Person, the member of the Platinum Group, Affiliate of a member of the
Platinum Group, Board Participant or Affiliated Officer of the Company shall have no duty (contractual or otherwise) to communicate or present such corporate opportunity to the Company or any Subsidiary of the Company, as the case may be, and,
notwithstanding any provision of this Agreement to the contrary, shall not be liable to the Company or its Affiliates or any Stockholder for breach of any duty (contractual or otherwise) by reason of the fact that such member of the Platinum Group,
Affiliate of a member of the Platinum Group, Board Participant or Affiliated Officer, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person, or does not present such opportunity to the
Company of any Subsidiary of the Company; provided, however, that this Section 4.5 shall not apply to any Board Participant who is also an officer or employee of the Company or any of its Subsidiaries (other than Affiliated
Officers). 
 (b) In addition to, and not in limitation of, the rights set forth in Section 4.5(a), the
parties hereto acknowledge and agree that each member of the Platinum Group, each Affiliate of a member of the Platinum Group, each Board Participant and each Affiliated Officer has the right to, and shall have no duty (contractual or otherwise) not
to, directly or indirectly engage in transactions with the Company and its Subsidiaries and Affiliates if such transactions are permitted by, or are approved in accordance with the procedures set forth in, the Platinum Fund I Partnership Agreement
or the Platinum Fund II Partnership Agreement, including without limitation transactions that are not negotiated on an arm’s-length basis. 

Section 4.6 Delivery of Financial Statements. So long as a Stockholder holds at least 1.0% of the Company’s outstanding
Common Stock, the Company will deliver promptly to such Stockholder copies of its quarterly and annual financial statements (“Financial Statements”); provided that (i) such Financial Statements are prepared by the
Company in the ordinary course of its business and distributed to the holders of the Company’s outstanding debt securities and (ii) no Stockholder shall lose their right to receive such Financial Statements to the extent that they hold
less than 1.0% of the Company’s outstanding Common Stock but has not Transferred any shares of the Company’s Common Stock acquired by it; and provided further that, for the purposes of this Section 4.6,
(a) Assignor, Assignee and their respective Affiliates, collectively, 
  

 15 

 
shall be treated as one Stockholder, (b) neither Assignor nor Assignee shall be deemed to have Transferred any shares of Common Stock solely due to any Transfer occurring between Assignor
and Assignee and (c) delivery of Financial Statements to Assignor shall be deemed to satisfy delivery of such Financial Statements to Assignee and any Affiliate of Assignor or Assignee who is a Stockholder hereunder.

 Section 5.9 Arbitration. To the fullest extent permitted by law, any dispute,
controversy or claim arising out of or relating to this Agreement or the agreements delivered in connection with this Agreement or the transactions contemplated by this Agreement or by the agreements delivered in connection with this Agreement,
including, without limitation, the validity, interpretation, performance, breach, alleged breach or termination of this Agreement, whether arising during the existence of the Partnership or at or after its termination or during or after the
liquidation of the Partnership, shall be resolved by mandatory binding confidential arbitration. Arbitration shall take place pursuant to Delaware law before either JAMS/Endispute pursuant to JAMS Comprehensive Arbitration Rules and Procedures
(including interim measures), or before Action Dispute Resolution Services pursuant to the ADR Services Arbitration Rules (including interim measures) (whichever arbitration service the claimant elects upon filing an arbitration), in Los Angeles,
California, and will be heard and decided by a sole, neutral arbitrator (the “Arbitrator”) selected either by agreement of the parties, or if the parties are unable to agree, then selected under the rules of the selected arbitration
service. Arbitration shall not apply to any claims which cannot by law be resolved through arbitration (e.g., claims for workers’ compensation benefits). The Company shall bear the costs and fees associated with any Arbitrator or arbitration
service. The parties shall have the right to conduct discovery in accordance with California Code of Civil Procedure §1283.05 et seq. and the written discovery requests and results of discovery shall be deemed to constitute confidential
information pursuant to Section 5.14. The Arbitrator shall have the right to impose any and all legal and equitable remedies that would be available to any party before any governmental dispute resolution forum or court of competent
jurisdiction, including, without limitation, injunctive relief, compensatory damages, actual damages, liquidated damages, accounting, disgorgement, specific performance, attorneys’ fees and costs and punitive damages. The Arbitrator shall
render a written opinion which contains his or her factual and legal reasoning. Each party shall bear its own attorneys’ fees, expert fees, consulting fees and other litigation costs (if any) ordinarily associated with legal proceedings taking
place in a judicial forum, subject to the Arbitrator’s reassessment in favor of the prevailing party (but only to the extent permitted by Delaware law). Each party understands, acknowledges and agrees that by agreeing to arbitration, it is
giving up any right that it may have to a trial by judge or jury with regard to the matters which are required to be submitted to mandatory and binding arbitration. Each party further understands, acknowledges and agrees that there is no right to an
appeal or a review of an Arbitrator’s award as there would be a right of appeal or review of a judge or jury’s decision. The party who prevails in any arbitration may seek to have the Arbitrator’s award entered as a judgment of the
Los Angeles Superior Court (or other court of competent jurisdiction), and any party may apply to the court on an ex parte application or noticed motion without opposition for a stipulated order sealing the documents filed in such proceeding to
maintain the confidentiality of confidential information to the greatest extent permitted by law. 
 Section 5.10
Section Headings. The section headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement. 

Section 5.11 Entire Agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto
relating to the subject matter hereof and supersedes any and all prior agreements and understandings, written or oral, relating to the subject matter hereof. 
  

 18 

 Section 5.12 Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or
affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdictions, it being intended that all rights and obligations of the parties hereunder shall be enforceable to the fullest extent permitted
by law. 
 Section 5.13 Counterparts. This Agreement may be signed in counterparts, each of which shall constitute
an original and which together shall constitute one and the same agreement.

as required by law or the rules of any applicable securities exchange or national market system, any announcements or similar publicity or any disclosure to any person other than the respective advisors of the parties hereto regarding the contents
of this Agreement or any other agreement between the parties entered into pursuant thereto shall be agreed upon by Platinum prior to such disclosure and, except as provided herein, any information relating to the matters described above shall be
kept confidential by the parties hereto (and their respective representatives and agents). 
 Section 5.15 Parties in
Interest. This Agreement and all the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and Permitted Transferees. Neither this Agreement nor any of their rights hereunder shall
be assigned by any of the parties hereto who are not Permitted Transferees without the prior written consent of the other parties. 

Section 5.16 Enforcement; Further Assurances. 

(a) The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms. It is accordingly agreed that the parties shall be entitled to specific performance of the terms hereof, this being in addition to any other remedy to which they are entitled at law or in
equity. 
 (b) The parties hereto agree to execute, acknowledge, deliver, file and record such further
certificates, amendments, instruments, agreements and documents, and to do all such other acts and things, as may be required by law or as may be necessary or advisable to carry out the intent and purposes of this Agreement.
