exercised only by the Participant. Notwithstanding the foregoing and to the extent permitted by Section 422 of the Code and applicable law, the Plan 
  

 -14- 

 Administrator, in its sole discretion, may permit a Participant to assign or transfer an Award, and may permit
distribution of an Option to an inter vivos or testamentary trust in which the Option is to be passed to beneficiaries upon the death of the trustor (settlor), or by gift to “immediate family” as that term is defined in Rule 16a-l(e) under
the Exchange Act; provided, however, that any Award so assigned or transferred shall be subject to all the terms and conditions of the Plan and the instrument evidencing the Award. 
 SECTION 13. ADJUSTMENTS 
 13.1 Adjustment of Shares 
 In the event, at any time or from time to time, a stock dividend, stock split, spin-off, combination or exchange of shares, recapitalization, merger, consolidation,
distribution to stockholders other than a normal cash dividend, or other change in the Company’s corporate or capital structure results in (a) the outstanding shares of Common Stock, or any securities exchanged therefor or received in
their place, being exchanged for a different number or kind of securities of the Company or any other company or (b) new, different or additional securities of the Company or any other company being received by the holders of shares of Common
Stock, then the Plan Administrator shall make proportional adjustments in (i) the maximum number and kind of securities available for issuance under the Plan; (ii) the maximum number and kind of securities issuable as Incentive Stock
Options as set forth in Section 4.2(d); and (iii) the number and kind of securities that are subject to any outstanding Award and the per share price of such securities, without any change in the aggregate price to be paid therefor.

 The determination by the Plan Administrator as to the terms of any of the foregoing adjustments shall be conclusive and binding. 
 Notwithstanding the foregoing, the issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or
property, or for labor or services rendered, or for other valid consideration, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such
shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, outstanding Awards. Also notwithstanding the foregoing, a dissolution or liquidation of the Company or a Company Transaction shall not
be governed by this Section 13.1 but shall be governed by the remaining provisions of this Section 13. 
 13.2 Dissolution or Liquidation

 To the extent not previously exercised or settled, and unless otherwise determined by the Plan Administrator in its sole discretion, Options, Stock
Appreciation Rights and Stock Units shall terminate immediately prior to the dissolution or liquidation of the Company. To the extent a forfeiture provision or repurchase right applicable to an Award has not been waived by the Plan Administrator,
the Award shall be forfeited immediately prior to the consummation of the dissolution or liquidation. 
  

 -15- 

 13.3 Company Transaction 
 13.3.1 Options, Stock Appreciation Rights and Stock Units 
 (a) In the event of a Company Transaction, except as
otherwise provided in the instrument evidencing the Award or in a written employment, services or other agreement between a Participant and the Company or a Related Company, 
 (i) all Options and Stock Appreciation Rights outstanding and held by a Participant whose employment or service relationship has not terminated as of the
date of the Company Transaction or is terminated other than for Cause within 30 days prior to the Company Transaction shall, immediately prior to the Company Transaction, become fully vested and exercisable with respect to 100% of the unvested
portion of the Award; and 
 (ii) all Stock Units outstanding and held by a Participant whose employment or service relationship has not
terminated as of the date of the Company Transaction or is terminated other than for Cause within 30 days prior to the Company Transaction shall, immediately prior to the Company Transaction, become fully vested and shall be settled with respect to
100% of the unvested portion of the Award; provided, however, that 
 (iii) notwithstanding the foregoing, such accelerated vesting and
exercisability or settlement of such Options, Stock Appreciation Rights and Stock Units shall not occur 
 (A) if and to the extent any
Successor Company assumes or continues such Options, Stock Appreciation Rights or Stock Units, or substitutes reasonably equivalent options, rights or units or 
 (B) if the Plan Administrator determines, in its sole discretion, that to the extent any Successor Company does not assume or continue such Options, Stock Appreciation Rights or Stock Units, or substitute equivalent
options, rights or units, any portion of such Awards that is not assumed, continued or substituted for by the Successor Company shall terminate immediately prior to the Company Transaction in exchange for a cash payment at least equal to the amount,
if any, by which the Acquisition Price multiplied by the number of shares of Common Stock subject to such Award, either to the extent the Award is vested and exercisable in accordance with its original terms or as such vesting and exercisability may
be accelerated by the Plan Administrator, in its sole discretion, in connection with the Company Transaction, exceeds the aggregate exercise or grant price, if any, for such Award. 
 (b) Immediately following a Company Transaction, all outstanding Options, Stock Appreciation Rights and Stock Units shall terminate and cease to be outstanding, except to the extent assumed, continued or substituted
for by the Successor Company. 
  

 -16- 

 13.3.2 Restricted Stock 
 In the event of a Company Transaction, except as otherwise provided in the instrument evidencing the Award or in a written employment, services or other agreement between a Participant and the Company or a Related
Company, the restrictions applicable to all Restricted Stock outstanding as of the date of the Company Transaction shall not lapse, any Company repurchase rights shall automatically be assigned to the Successor Company, and all such restrictions
shall continue with respect to any shares of the Successor Company or other consideration that may be issued in exchange or in substitution for such Restricted Stock. 
 13.3.3 Assumption, Continuation or Substitution 
 For the purposes of this Section 13.3, an Award shall be
considered assumed, continued or substituted for if, following the Company Transaction, the substitute award confers the right to purchase or receive, for each share of Common Stock subject to the Award immediately prior to the Company Transaction,
the consideration (whether stock, cash, or other securities or property) received in the Company Transaction by holders of Common Stock for each share subject to the Award immediately prior to the Company Transaction (and if holders were offered a
choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares) without any change in the aggregate exercise or grant price, if any, of such Award; provided, however, that if such consideration
received in the Company Transaction is not solely common stock of the Successor Company, the Plan Administrator may, with the consent of the Successor Company, provide for the consideration to be received upon the exercise or settlement of the
Award, for each share of Common Stock subject to the Award, to be solely common stock of the Successor Company substantially equal in fair market value to the per share consideration received by holders of Common Stock in the Company Transaction.
The determination of such substantial equality of value of consideration shall be made by the Plan Administrator, whose determination shall be conclusive and binding. 
 13.4 Further Adjustment of Awards 
 Subject to Sections 13.2 and 13.3, the Plan Administrator shall have the
discretion, exercisable at any time before a sale, merger, consolidation, reorganization, liquidation, dissolution or change in control of the Company, as defined by the Plan Administrator, to take such further action as it determines to be
necessary or advisable with respect to Awards. Such authorized action may include (but shall not be limited to) establishing, amending or waiving the type, terms, conditions or duration of, or restrictions on, Awards so as to provide for earlier,
later, extended or additional time for exercise, lifting restrictions and other modifications, and the Plan Administrator may take such actions with respect to all Participants, to certain categories of Participants or only to individual
Participants. The Plan Administrator may take such action before or after granting Awards to which the action relates and before or after any public announcement with respect to such sale, merger, consolidation, reorganization, liquidation,
dissolution or change in control that is the reason for such action. 
  

 -17- 

 13.5 Limitations 
 The
grant of Awards shall in no way affect the Company’s right to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business
or assets. 
 13.6 Fractional Shares 
 In the event of any
adjustment in the number of shares covered by any Award, each such Award shall cover only the number of full shares resulting from such adjustment. 
 SECTION 14. FIRST REFUSAL AND REPURCHASE RIGHTS 
 14.1 First Refusal Rights 
 Until the date on which the initial registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act first becomes effective, the Company shall have
the right of first refusal with respect to any proposed sale or other disposition by a Participant of any shares of Common Stock issued pursuant to an Award. Such right of first refusal shall be exercisable in accordance with the terms and
conditions established by the Plan Administrator and set forth in the stock purchase agreement evidencing the purchase of the shares. 
 14.2 Repurchase
Rights for Unvested Shares 
 The Plan Administrator may, in its sole discretion, authorize the issuance of unvested shares of Common Stock pursuant to
the exercise of an Option. Should the Participant cease to be employed by or provide services to the Company or a Related Company, then all shares of Common Stock issued upon exercise of an Option that are unvested at the time of cessation of
employment or service relationship shall be subject to repurchase at the exercise price paid for such shares. The terms and conditions upon which such repurchase right shall be exercisable (including the period and procedure for exercise) shall be
established by the Plan Administrator and set forth in the stock purchase agreement evidencing the purchase of the shares. 
 Except as otherwise provided in
the instrument evidencing the Award, in the event of a Company Transaction, the Company’s repurchase rights shall automatically be assigned to the Successor Company. 
 The Plan Administrator shall have the discretionary authority, exercisable either before or after a Participant’s Termination of Service, to waive the Company’s outstanding repurchase rights with respect to
one or more shares purchased or purchasable by the Participant under an Option and thereby accelerate the vesting of such shares in whole or in part at any time. 
  

 -18- 

 14.3 Repurchase Conditions 
 Notwithstanding the foregoing, to the extent required by applicable law the Company’s repurchase right set forth in Section 14.2 shall lapse at the rate of at least 20% of the shares per year over five years from the date the
Option is granted (without respect to the date the Option or is exercised or becomes exercisable) and the right to repurchase shall be exercised for cash or cancellation of purchase money indebtedness for the shares within 90 days of termination of
employment (or in the case of securities issued upon exercise of Options after the date of termination, within 90 days after the date of the exercise). 
 In
addition to the restrictions set forth in clauses (a) and (b), the securities held by an officer, director or consultant of the Company or a Related Company may be subject to additional or greater restrictions. 
 14.4 General 
 The Company’s
first refusal and repurchase rights under this Section 14 are assignable by the Company at any time. 
 SECTION 15. MARKET STANDOFF

 In the event of an underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under
the Securities Act, including the Company’s initial public offering, no person may sell, make any short sale of, loan, hypothecate, pledge, grant any option for the purchase of, or otherwise dispose of or transfer for value or otherwise agree
to engage in any of the foregoing transactions with respect to any shares issued pursuant to an Award granted under the Plan without the prior written consent of the Company or its underwriters. Such limitations shall be in effect for such period of
time as may be requested by the Company or such underwriters; provided, however, that in no event shall such period exceed 180 days following the effective date of the registration statement. The limitations of this Section 15 shall in all
events terminate two years after the effective date of the Company’s initial public offering. 
 In the event of any stock split, stock dividend,
recapitalization, combination of shares, exchange of shares or other change affecting the Company’s outstanding Common Stock effected as a class without the Company’s receipt of consideration, any new, substituted or additional securities
distributed with respect to the purchased shares shall be immediately subject to the provisions of this Section 15, to the same extent the purchased shares are at such time covered by such provisions. 
 In order to enforce the limitations of this Section 15, the Company may impose stop-transfer instructions with respect to the purchased shares until the end of the
applicable standoff period. 
  

 -19- 

 SECTION 16. AMENDMENT AND TERMINATION 
 16.1 Amendment, Suspension or Termination 
 The Board may amend,
suspend or terminate the Plan or any portion of the Plan at any time and in such respects as it shall deem advisable; provided, however, that, to the extent required by applicable law, regulation or stock exchange rule, stockholder approval shall be
required for any amendment to the Plan. Subject to Section 16.3, the Board may amend the terms of any outstanding Award, prospectively or retroactively. 
 16.2 Term of the Plan 
 The Plan shall have no fixed expiration date. After the Plan is terminated, no future Awards may be granted, but
Awards previously granted shall remain outstanding in accordance with their applicable terms and conditions and the Plan’s terms and conditions. Notwithstanding the foregoing, no Incentive Stock Options may be granted more than ten years after
the earlier of (a) the adoption of the Plan by the Board and (b) the adoption by the Board of any amendment to the Plan that constitutes the adoption of a new plan for purposes of Section 422 of the Code. Notwithstanding the
foregoing, no Award may be granted to a resident of California more than ten years after the earlier of the date of adoption of the Plan and the date the Plan is approved by the stockholders. 
 16.3 Consent of Participant 
 The amendment, suspension or termination
of the Plan or a portion thereof or the amendment of an outstanding Award shall not, without the Participant’s consent, materially adversely affect any rights under any Award theretofore granted to the Participant under the Plan. Any change or
adjustment to an outstanding Incentive Stock Option shall not, without the consent of the Participant, be made in a manner so as to constitute a “modification” that would cause such Incentive Stock Option to fail to continue to qualify as
an Incentive Stock Option. Notwithstanding the foregoing, any adjustments made pursuant to Sections 13.2 and 13.3 shall not be subject to these restrictions. 
 SECTION 17. GENERAL 
 17.1 No Individual Rights 
 No individual or Participant shall have any claim to be granted any Award under the Plan, and the Company has no obligation for uniformity of treatment of Participants under the Plan. Furthermore, nothing in the Plan
or any Award granted under the Plan shall be deemed to constitute an employment contract or confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any
Related Company or limit in any way the right of the Company or any Related Company to terminate a Participant’s employment or other relationship at any time, with or without cause. 
  

 -20- 

 17.2 Issuance of Shares 
 Notwithstanding any other provision of the Plan, the Company shall have no obligation to issue or deliver any shares of Common Stock under the Plan or make any other distribution of benefits under the Plan unless, in the opinion of the
Company’s counsel, such issuance, delivery or distribution would comply with all applicable laws (including, without limitation, the requirements of the Securities Act or the laws of any state or foreign jurisdiction) and the applicable
requirements of any securities exchange or similar entity. 
 The Company shall be under no obligation to any Participant to register for offering or resale
or to qualify for exemption under the Securities Act, or to register or qualify under the laws of any state or foreign jurisdiction, any shares of Common Stock, security or interest in a security paid or issued under, or created by, the Plan, or to
continue in effect any such registrations or qualifications if made. 
 As a condition to the exercise of an Option or any other receipt of Common Stock
pursuant to an Award under the Plan, the Company may require (a) the Participant to represent and warrant at the time of any such exercise or receipt that such shares are being purchased or received only for the Participant’s own account
and without any present intention to sell or distribute such shares and (b) such other action or agreement by the Participant as may from time to time be necessary to comply with the federal, state and foreign securities laws. At the option of
the Company, a stop-transfer order against any such shares may be placed on the official stock books and records of the Company, and a legend indicating that such shares may not be pledged, sold or otherwise transferred, unless an opinion of counsel
is provided (concurred in by counsel for the Company) stating that such transfer is not in violation of any applicable law or regulation, may be stamped on stock certificates to ensure exemption from registration. The Plan Administrator may also
require the Participant to execute and deliver to the Company a purchase agreement or such other agreement as may be in use by the Company at such time that describes certain terms and conditions applicable to the shares. 
 To the extent the Plan or any instrument evidencing an Award provides for issuance of stock certificates to reflect the issuance of shares of Common Stock, the issuance
may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange. 
 17.3 No
Rights as a Stockholder 
 Unless otherwise provided by the Plan Administrator or in the instrument evidencing the Award or in a written employment,
services or other agreement, no Option, Stock Appreciation Right or Stock Unit shall entitle the Participant to any cash dividend, voting or other right of a stockholder unless and until the date of issuance under the Plan of the shares that are the
subject of such Award. 
  

 -21- 

 17.4 Compliance With Laws and Regulations 
 In interpreting and applying the provisions of the Plan, any Option granted as an Incentive Stock Option pursuant to the Plan shall, to the extent permitted by law, be construed as an “incentive stock
option” within the meaning of Section 422 of the Code. 
 17.5 Participants in Other Countries 
 The Plan Administrator shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with provisions of the
laws of other countries in which the Company or any Related Company may operate to ensure the viability of the benefits from Awards granted to Participants employed in such countries, to comply with applicable foreign laws and to meet the objectives
of the Plan. 
 17.6 No Trust or Fund 
 The Plan is
intended to constitute an “unfunded” plan. Nothing contained herein shall require the Company to segregate any monies or other property, or shares of Common Stock, or to create any trusts, or to make any special deposits for any immediate
or deferred amounts payable to any Participant, and no Participant shall have any rights that are greater than those of a general unsecured creditor of the Company. 
 17.7 Successors 
 All obligations of the Company under the Plan with respect to Awards shall be binding on any
successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all the business and/or assets of the Company. 
 17.8 Severability 
 If any provision of the Plan or any Award is
determined to be invalid, illegal or unenforceable in any jurisdiction, or as to any person, or would disqualify the Plan or any Award under any law deemed applicable by the Plan Administrator, such provision shall be construed or deemed amended to
conform to applicable laws, or, if it cannot be so construed or deemed amended without, in the Plan Administrator’s determination, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such
jurisdiction, person or Award, and the remainder of the Plan and any such Award shall remain in full force and effect. 
 17.9 Choice of Law

 The Plan, all Awards granted thereunder and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by the laws
of the United States, shall be governed by the laws of the State of California without giving effect to principles of conflicts of law. 
  

 -22- 

 17.10 Financial Reports 
 To the extent required by applicable law, the Company shall provide annual financial statements of the Company to each Participant. Such financial statements need not be audited and need not be issued to employees whose duties within the
Company assure them access to equivalent information. 
 SECTION 18. EFFECTIVE DATE 
 The effective date (the “Effective Date”) is the date on which the Plan is adopted by the Board. If the stockholders of the Company do not
approve the Plan within 12 months after the Board’s adoption of the Plan, (a) any Award exercised or settled before the stockholders of the Company approve the Plan shall be rescinded and any such shares shall not be counted in determining
whether such stockholder approval is obtained, and (b) any Incentive Stock Options granted under the Plan will be treated as Nonqualified Stock Options.

 The Company and the Guarantors have heretofore executed and delivered to the Trustee an indenture dated as of March 11, 2003 (the “Original

the context clearly requires otherwise, the use of terms and expressions herein is in accordance with the definitions, uses and constructions contained in the Original Indenture. 
 ARTICLE TWO 
 AMENDMENTS 
 Section 201. Amendments to the Indenture. Subject to the execution and delivery hereof by the parties hereto, the Indenture is hereby amended
as follows: 
 (a) Subsection (d) of the definition of “Permitted Indebtedness” in Section 101 of the Indenture is hereby
amended and restated to read as follows: 
 (d) (i) Indebtedness of the Company or any Restricted Subsidiary incurred under the Amended
Credit Agreement in an aggregate principal amount at any one time outstanding not to exceed the greater of (x) $90,000,000 and (y) the sum of $45,000,000 and the Borrowing Base at the time such Indebtedness was incurred, or any
refinancing, refunding, deferral, renewal or extension thereof not in excess of such amount; and 
 (ii) Indebtedness of the
Company or any Restricted Subsidiary incurred prior to December 31, 2006 in an aggregate principal amount up to $25,000,000, or any refinancing, refunding, deferral, renewal or extension thereof not in excess of such amount. 
 (b) Section 1001 is hereby amended to add the following sentence: 
 In addition, the Company agrees that on September 15, 2006 the Company shall make a cash payment (the “Consent Fee”) of $5.00 per $1,000 principal amount of Securities as to which a Holder (as defined
in the Company’s Consent Solicitation Statement dated March 30, 2006 (the “Consent Statement”)) as of the close of business on March 29, 2006 has 

  

 2 

 
delivered a duly executed consent (the “Consent”) to the terms of the First Supplemental Indenture attached as Exhibit A to the Consent Statement
prior to the Expiration Date (as defined in the Consent Statement) that was not revoked prior to the date of such First Supplemental Indenture (such Holders being hereinafter referred to as the “Consenting Holders”), which Consent Fee
shall be paid in accordance with the terms of the Consent. 
 (c) Section 501(1) shall be amended to read in its entirety as follows:

 There shall be a default in the payment of interest on any Security or the Consent Fee when the same becomes due and payable and the
Default continues for a period of thirty (30) days. 
 (d) A new Section 1021 is hereby added to the Indenture, to read as follows:

 Section 1021. Indebtedness. The Company shall deliver to the Trustee, on or before May 15, 2007, an Officers’
Certificate stating whether Indebtedness of the Company evidenced by the Securities plus Indebtedness of the Company and the Restricted Subsidiaries secured by liens on assets of the Company and/or the Restricted Subsidiaries (collectively, the
“Indenture Indebtedness and Secured Indebtedness”) outstanding on March 30, 2007 was in excess of Indenture Indebtedness and Secured Indebtedness outstanding on March 31, 2006; provided, however, that for purposes of calculating
the Indenture Indebtedness and Secured Indebtedness as of March 31, 2006 within the meaning of this Section 1021, any Indebtedness of the Company or any Restricted Subsidiary incurred on or before March 31, 2006 pursuant to Subsection
(d)(ii) of the definition of Permitted Indebtedness in Section 101 hereof shall be omitted and any Indebtedness of the Company or any Restricted Subsidiary that was repaid with the proceeds of such incurrence and was not reborrowed on or before

Holders as of March 30, 2007, an amount in cash equal to $10.00 per $1,000 principal amount of Securities held by such Consenting Holder on March 30, 2007 in immediately available funds.
