     SECTION 4.2 Tax Indemnity Obligations of the KRG Blocker Stockholders.

     (a) KRG Tax Returns. ARDX Inc. and the KRG Blocker Stockholders agree and acknowledge
that as a result of Corporate Merger, KRG Blocker shall cease to exist and its tax year shall end
for federal and applicable state, local and foreign income tax purposes on the Closing Date. The
KRG Blocker Stockholders shall appoint a designee (the “KRG Designee”) to prepare and file
all Tax Returns of KRG Blocker with respect to any taxable year or period that ends on or before
the Closing Date and any taxable year or period beginning before and ending after the Closing Date,
which are due after the Closing Date. The KRG Designee shall prepare or cause to be prepared such
Tax Returns in accordance with the procedures, practices and accounting methods of KRG Blocker in
effect as of the date hereof. With respect to such Tax Returns, the KRG Designee shall provide
drafts of such Tax Returns to ARDX Inc. for its review and comment no later than thirty (30) days
prior to the due date for filing such Tax Returns, such comments to be delivered to the KRG
Designee within the next twenty (20) days. The KRG Designee shall make all such revisions and
otherwise implement all such comments provided by ARDX Inc. that the KRG Designee, in its sole
discretion and in good faith, deems reasonable. ARDX Inc. shall cooperate with the KRG Designee in
filing such Tax Returns, including causing the applicable entities to sign and file such Tax
Returns.

     (b) Tax Indemnity. The KRG Blocker Stockholders shall indemnify and hold harmless ARDX
Inc. from any and all liabilities, losses, damages, deficiencies, assessments, judgments and costs
or expenses (including out-of-pocket expenses for investigation and defense and reasonable
attorneys’ fees) actually incurred or sustained by ARDX Inc. with respect to or in connection with
Taxes imposed on ARDX Inc. as successor to KRG Blocker that are attributable to any taxable period
ending on or before the Closing Date and with respect to any taxable period that includes but does
not end on the Closing Date, the portion of such period that ends on and includes the Closing Date
(“Pre-Closing Tax Period”) (including as a result of the Corporate Merger, but excluding
Taxes attributable to events subsequent to the Corporate Merger Effective Time) of the KRG Blocker.

     (c) Cooperation on Tax Matters.

     (i) Unless otherwise required by law, ARDX Inc. shall not take any action which could
reasonably be expected to increase the liability of the KRG Blocker Stockholders for Taxes
attributable to any Pre-Closing Tax Period (including any action which could reasonably be
expected to increase the liability of the KRG Blocker Stockholders attributable to the
Corporate

11

 

Merger) under this Agreement without the prior written consent of the KRG Designee,
which may be withheld by the KRG Designee in its sole discretion. ARDX Inc. shall not amend,
refile or otherwise modify any applicable portion of any Tax Return or Tax election of KRG
Blocker for any Pre-Closing Tax Period, or take any other action with respect to such a Tax
Return, that could reasonably be expected to increase the liability of the KRG Blocker
Stockholders for Taxes under this Agreement, without the prior written consent of the KRG
Designee, which consent may be withheld by the KRG Designee in its sole discretion. Except
as otherwise contemplated by this Agreement, ARDX Inc. shall not take any action from and
after the date of this Agreement but prior to the Corporate Merger Effective Time that is
outside the ordinary course of business.

     (ii) After the date of this Agreement, ARDX Inc. shall not, without the written consent
of the KRG Designee, agree to waive or extend the statute of limitations relating to any
Taxes of KRG Blocker for any Pre-Closing Tax Period.

     (iii) ARDX Inc. shall notify the KRG Designee in writing within ten (10) days upon
receipt by ARDX Inc. of notice of any pending or threatened federal, state, local or foreign
Tax audits, assessments, or administrative or judicial proceedings affecting the Taxes or
Tax attributes of KRG Blocker that could result in any Tax liability for which the KRG
Blocker Stockholders may be liable to ARDX Inc. hereunder (a “KRG Tax Claim”). Such
notice shall contain factual information describing any asserted Tax liability and shall
include copies of any notice or other document received from any taxing authority in respect
of any such asserted Tax liability.

     (iv) ARDX Inc. and the KRG Designee shall cooperate fully, as and to the extent
reasonably requested by the other party, in connection with the filing of Tax Returns
pursuant to Section 4.2(a) and any audit, assessment, litigation or other proceeding
with respect to Taxes, and each shall (i) retain all books and records with respect to Tax
matters pertinent to KRG Blocker until the expiration of the statute of limitations
(including any extensions thereof) applicable to such taxable periods, and to abide by all
record retention agreements entered into with any taxing authority and (ii) to give to the
other party reasonable written notice prior to transferring, destroying or discarding any
such books and records and, if such other party so requests, the party will allow the other
party to take possession of such books and records.

     (d) Tax Contests. The KRG Designee shall, at its own expense, have the right to
control the contest of any KRG Tax Claim (a “KRG Tax Proceeding”) provided that (i) ARDX
Inc. may participate in the conduct of such KRG Tax Proceeding at its own expense, and (ii) the
settlement or other resolution of such KRG Tax Proceeding shall be subject to the written consent
of ARDX Inc., which consent shall not be unreasonably withheld, conditioned or delayed; provided,
however, that no such consent shall be required where such settlement provides for the payment by
the KRG Blocker, the KRG Blocker Stockholders, or the KRG Designee of money as the sole remedy and
includes as an unconditional term thereof the giving by the claimant of a release from all
liability with respect to such KRG Tax Claim.

     (e) Tax Refunds. Any refunds for Taxes (including any interest in respect thereof)
received by ARDX Inc., and any amounts credited against Taxes to which ARDX Inc. becomes entitled
(including by way of any amended Tax Return), that relate to Pre-Closing Tax Period of the KRG
Blocker, shall be property of the KRG Blocker Stockholders, except in each case to the extent such
refund or credit resulted from the carryback of a net operating loss or other Tax attribute that
was economically generated after the date of this Agreement. ARDX Inc. shall pay to the KRG
Designee any such refund or the amount of any such credit within fifteen (15) days after receipt or
entitlement thereto.

     (a) Summit Tax Returns. ARDX Inc. and the Summit Blocker Stockholders agree and
acknowledge that as a result of the Corporate Merger, the Summit Blockers shall cease to exist and
its tax year shall end for federal and applicable state, local and foreign income tax purposes on

beginning before and ending after the Closing Date, which are due after the Closing Date. The

procedures, practices and accounting methods of the Summit Blockers in effect as of the date
hereof. With respect to such Tax Returns, the Summit Designee shall provide drafts of such Tax
Returns to ARDX Inc. for its review and comment no later than thirty (30) days prior to the due
date for filing such Tax Returns, such comments to be delivered to the Summit Designee within the
next twenty (20) days. The Summit Designee shall make all such revisions and otherwise implement
all such comments provided by ARDX Inc. that the Summit Designee, in its sole discretion and in
good faith, deems reasonable. ARDX Inc. shall cooperate with the Summit Designee in filing such
Tax Returns, including causing the applicable entities to sign and file such Tax Returns.

     (b) Tax Indemnity.

     (i) Summit Ventures VI-B, L.P. shall indemnify and hold harmless ARDX Inc. from any and
all liabilities, losses, damages, deficiencies, assessments, judgments and costs or expenses
(including out-of-pocket expenses for investigation and defense and reasonable attorneys’
fees) actually incurred or sustained by ARDX Inc. with respect to or in connection with
Taxes imposed on ARDX Inc. as successor to the Summit Blocker 1 that are attributable to any
Pre-Closing Tax Period (including as a result of the Corporate Merger, but excluding Taxes
attributable to events subsequent to the Corporate Merger Effective Time) of the Summit
Blocker 1.

     (ii) Summit Partners Private Equity Fund VII-B, L.P. shall indemnify and hold harmless
ARDX Inc. from any and all liabilities, losses, damages, deficiencies, assessments,

respect to or in connection with Taxes imposed on ARDX Inc. as successor to the Summit
Blocker 2 that are attributable to any Pre-Closing Tax Period (including as a result of the

Merger Effective Time) of the Summit Blocker 2.

     (c) Cooperation on Tax Matters.

     (i) Unless otherwise required by law, ARDX Inc. shall not take any action which could
reasonably be expected to increase the liability of the Summit Blocker Stockholders for
Taxes attributable to any Pre-Closing Tax Period (including any action which could
reasonably be expected to increase the liability of the Summit Blocker Stockholders
attributable to the Corporate Merger) under this Agreement without the prior written consent
of the Summit Designee, which may be withheld by the Summit Designee in its sole discretion.
ARDX Inc. shall not amend, refile or otherwise modify any applicable portion of any Tax
Return or Tax election of the Summit Blockers for any Pre-Closing Tax Period, or take any
other action with respect to such a Tax Return, that could reasonably be expected to
increase the liability of the Summit Blocker Stockholders for Taxes under this Agreement,
without the prior written consent of the Summit Designee, which consent may be withheld by
the Summit Designee in its sole discretion. Except as otherwise contemplated by this
Agreement, ARDX Inc. shall not take any action from
and after the date of this Agreement but prior to the Corporate Merger Effective Time
that is outside the ordinary course of business.

13

 

     (ii) After the date of this Agreement, ARDX Inc. shall not, without the written consent
of the Summit Designee, agree to waive or extend the statute of limitations relating to any
Taxes of the Summit Blockers for any Pre-Closing Tax Period.

     (iii) ARDX Inc. shall notify the Summit Designee in writing within ten (10) days upon
receipt by ARDX Inc. of notice of any pending or threatened federal, state, local or foreign
Tax audits, assessments, or administrative or judicial proceedings affecting the Taxes or
Tax attributes of the Summit Blockers that could result in any Tax liability for which the
Summit Blocker Stockholders may be liable to ARDX Inc. hereunder (a “Summit Tax
Claim”). Such notice shall contain factual information describing any asserted Tax
liability and shall include copies of any notice or other document received from any taxing
authority in respect of any such asserted Tax liability.

     (iv) ARDX Inc. and the Summit Designee shall cooperate fully, as and to the extent

other party reasonable written notice prior to transferring, destroying or discarding any
such books and records and, if such other party so requests, the party will allow the other
party to take possession of such books and records.

     (d) Tax Contests. The Summit Designee shall, at its own expense, have the right to

payment by the Summit Blockers, the Summit Blocker Stockholders, or the Summit Designee of money as
the sole remedy and includes as an unconditional term thereof the giving by the claimant of a
release from all liability with respect to such Summit Tax Claim.

     (e) Tax Refunds. Any refunds for Taxes (including any interest in respect thereof)
received by ARDX Inc., and any amounts credited against Taxes to which ARDX Inc. becomes entitled
(including by way of any amended Tax Return), that relate to any Pre-Closing Tax Period of the
Summit Blockers, shall be property of the Summit Blocker Stockholders, except in each case to the
extent such refund or credit resulted from the carryback of a net operating loss or other Tax
attribute that was economically generated after the date of this Agreement. ARDX Inc. shall pay to
the Summit Designee any such refund or the amount of any such credit within fifteen (15) days after
receipt or entitlement thereto.

     SECTION 4.4 Tax Allocation Provisions. In the case of any Tax Return for a
Pre-Closing Tax Period that does not end on the Closing Date (a “Straddle Period”), and for
purposes of determining hereunder the amount of Taxes attributable to a Pre-Closing Tax Period or
any taxable period (or portion thereof) that is not a Pre-Closing Tax Period generally, the amount
of Taxes attributable to the Pre-Closing Tax Period shall be deemed to be (i) in the case of Taxes
imposed on a periodic basis (such as certain franchise Taxes, real or personal property Taxes), the
amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears
basis, the amount of such Taxes for the

14

 

immediately preceding period) multiplied by a fraction, the numerator of which is the number of
calendar days in the Straddle Period ending on and including the Closing Date and the denominator
of which is the number of calendar days in the entire relevant Straddle Period and (ii) in the case
of Taxes not described in (i) above (such as Taxes that are based upon or related to income or
receipts, based upon occupancy or imposed in connection with any sale or other transfer or
assignment of property (real or personal, tangible or intangible)), the amount of any such Taxes
shall be determined as if such taxable period and the taxable period ended of as of the close of
business on the Closing Date.

Exhibit 10.2

Summary Description of Management Incentive Plan

The Company has an annual short-term incentive compensation plan, which is provided to members of
the Company’s management, including but not limited to all of its Executive Officers, through the
Management Incentive Plan (“MIP”). The MIP is designed to be competitive with compensation
offerings in our peer comparator group and to align compensation with financial performance drivers
that are intended to benefit stockholders. Specific measures are determined by the Compensation
Committee of the Board of Directors (the “Compensation Committee”) prior to or in the first quarter
of the fiscal year for the potential annual MIP payout in question.

Performance measures under the MIP may include, but are not limited to, the following categories:

	•	 	Total Company financial results, such as earnings per share, cash flow, return on assets or
capital, or other financial results as determined by the Compensation Committee.

	 
	•	 	Financial results associated with the Company’s business segments:

	 	•	 	Turbine Systems

	 
	 	•	 	Airframe Systems

	 
	 	•	 	Electrical Power Systems

	 
	 	•	 	Engine Systems

	•	 	Additional performance metrics (either at the Company or the
business segment level) related to quality, delivery,
responsiveness, cost or other performance measures as determined
by the Compensation Committee from time to time.

	 
	•	 	Individual focused goals may also be used, as may be determined by
the Compensation Committee from time to time.

The Compensation Committee has discretion to predetermine and modify the performance measures and
threshold, target and maximum amounts payable under the plan.

Financial performance or other performance metrics are measured as of the last day of the fiscal
year and are validated prior to payout under the MIP for such fiscal year.
