 “SECTION 2.03A. Fronting Advances. (a) Fronting Events. Subject to the terms and conditions set forth in this
Section 2.03A, upon delivery of a Notice of Borrowing requesting a Borrowing in a Committed Foreign Currency pursuant to Section 2.02(a) (a “Fronting Event”), the Fronting Bank agrees, subject to the limitations set
forth below, to fund the applicable amount then required to be funded in such Committed Foreign Currency by each applicable Non-Qualified Lender (a “Fronting Advance”), notwithstanding the fact that such Fronting Advance,
when aggregated with the Pro Rata Share of the Facility Exposure of the Fronting Bank (in its capacity as a Lender), may exceed the amount of the Fronting Bank’s Revolving Credit Commitment; provided that after giving effect to each
Fronting Advance the aggregate Equivalent in Dollars of all Fronting Advances funded by the Fronting Bank shall not exceed the respective Fronting Commitment allocated to such Non-Qualified Lender as specified on Schedule I attached hereto (such
Fronting Commitments, collectively, the “Fronting Facility”). Immediately upon the making of a Fronting Advance on behalf of a Non-Qualified Lender, such Non-Qualified Lender shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Fronting Bank a risk participation in one hundred percent (100%) of such Fronting Advance. The purchase of such risk participation in each Fronting Advance by such Non-Qualified Lender shall satisfy
such Non-Qualified Lender’s funding requirements under Section 2.02(a). 
 (b) Fronting Commitment. If
following delivery of a Notice Borrowing requesting a Borrowing in a Committed Foreign Currency pursuant to Section 2.02(a) (a “Requested Borrowing”), the Fronting Bank, based on the limitations set forth in the proviso
to the first sentence of Section 2.03A, is unable to fund the entire corresponding Fronting Advance in such Committed Foreign Currency, then the Fronting Bank will give the Borrower and the Administrative Agent notice of such limitation on the
day it obtains knowledge thereof (which notice may be telephonic) and the Borrower may decrease the amount of the Requested Borrowing within one (1) Business Day after receipt of such notice. If the Borrower does not reduce its Requested
Borrowing to an amount that will result in the corresponding Fronting Advance being less than or equal to the available 

  

 6 

 
Fronting Commitment subject to the limitation set forth in the proviso to the first sentence in Section 2.03A, then (1) the Requested Borrowing
shall be deemed to be reduced in an amount sufficient to result in the corresponding Fronting Advances being equal to the available Fronting Commitments (a “Reduced Borrowing”) and (2) the Borrower shall be deemed to
have requested an additional Borrowing in an amount equal to the Equivalent in Dollars of the excess of the Requested Borrowing over the Reduced Borrowing, which shall be made by the Lenders without the utilization of any Fronting Advances.

 (c) Allocation of Payments. Following the making of any Fronting Advance by the Fronting Bank hereunder, prior to
the date the applicable Non-Qualified Lender that holds the 100% risk participation in such Fronting Advance funds such risk participation pursuant to this Section 2.03A to refinance such Fronting Advance, (1) all payments of principal
made in respect of any Advances funded by the Fronting Bank on behalf of such Non-Qualified Lender shall be solely for the account of the Fronting Bank, and (2) all payments of interest made in respect of any Advances funded by the Fronting
Bank on behalf of such Non-Qualified Lender shall be solely for the account of such Non-Qualified Lender, provided that the interest paid to such Non-Qualified Lender shall be reduced by the Fronting Fee payable pursuant to
Section 2.08(e). 
 (d) Sharing Events. Upon the occurrence of an Event of Default and the conversion of all
Advances denominated in any Committed Foreign Currency into Dollars pursuant to Section 2.09(b)(iii) (a “Sharing Event”), the Administrative Agent shall notify each Non-Qualified Lender of its obligation to fund its
participation in each Fronting Advance. Each Non-Qualified Lender shall make the amount of its participation in each such Fronting Advance available to the Administrative Agent for the account of the Fronting Bank, by deposit of such amount (in
Dollars) to the Administrative Agent’s Account, in same day funds, not later than 1:00 P.M. (New York City time) on the Business Day specified in such notice. 
 (e) Assignments to Qualified Lenders. To the extent that a Non-Qualified Lender that has a risk participation in a Fronting
Advance assigns all or part of its interest in such risk participation under Section 9.07 to a Qualified Lender, then (1) such assignee Lender shall make the amount of its assigned participation in such Fronting Advance available to the
Administrative Agent for the account of the Fronting Bank, by deposit of such amount (in the applicable currency) to the Administrative Agent’s Account, in same day funds, not later than 1:00 P.M. (New York City time) on the third
(3rd) Business Day following the effective date of the assignment and (2) such assignee shall continue to be treated hereunder as a Non-Qualified Lender for the sole purpose of computing the Fronting Fee on such Fronting Advance until such
time as such assignee shall have made the deposit required under clause (1) above, provided that (A) such assignee shall not be deemed to be a Non-Qualified Lender for any other purpose and (B) the Fronting Bank shall have no
obligation to make any Fronting Advances on behalf of such assignee. 
 (f) Failure to Make Payments. If any
applicable Lender fails to make available to the Fronting Bank any amount required to be paid by such Lender pursuant to Section 2.03A(d) or 2.03A(e) by the time specified therein, the 

  

 7 

 
Fronting Bank shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the
period from the date such payment is required to the date on which such payment is immediately available to the Fronting Bank at the Federal Funds Rate. A certificate of the Fronting Bank submitted to any applicable Lender (through the
Administrative Agent) with respect to any amount owing under this Section 2.03A(f) shall be conclusive absent manifest error. 
 (g) Obligations Absolute. Each applicable Lender’s obligation to purchase and fund risk participations in Fronting Advances pursuant to this Section 2.03A shall be absolute and unconditional and shall not be affected by any
circumstance, including (1) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Fronting Bank, any Loan Party or any other Person for any reason whatsoever, (2) the occurrence or continuance
of a Default or Event of Default, or (3) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay
the Fronting Bank, together with interest as provided herein. 
 (h) Funding of Risk Participations. At any time after
any Lender has purchased and funded a risk participation in a Fronting Advance, if the Fronting Bank receives any payment on account of such Fronting Advance, the Fronting Bank will distribute to such Lender such payment (appropriately adjusted to
reflect the period of time during which such Lender’s participation was funded) in the same funds and currency as those received by the Fronting Bank. 
 (i) Return of Payments. Notwithstanding the foregoing provisions of this Section 2.03A, if any payment referred to in
Section 2.03A(h) is required to be returned by the Fronting Bank in connection with any proceeding under any Bankruptcy Law or otherwise (including pursuant to any settlement entered into by the Fronting Bank in its direction), the Lender to
which the Fronting Bank paid such payment shall pay to the Fronting Bank in the applicable currency of such Fronting Advance the amount of such payment on demand of the Administrative Agent, plus interest thereon from the date of such demand to the
date such amount is returned, at the Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Fronting Bank. The obligations of the applicable Lenders under this Section 2.03A(i) shall survive the payment in
full of the Obligations of the Loan Parties under the Loan Documents and the termination of this Agreement.” 
 (j)
Section 2.05(b) of the Credit Agreement is hereby amended by adding the following new clause (iii) thereto as follows: 
 “(iii) The Fronting Facility shall be permanently reduced from time to time on the date of each reduction in the Revolving Credit Facility by the amount, if any, by which the amount of the Fronting Facility exceeds the Revolving Credit
Facility after giving effect to such reduction of the Revolving Credit Facility.”

annum equal to two-tenths of one percent (0.20%) (a “Fronting Fee”). Such Fronting Fee shall be payable only upon receipt by the Administrative Agent of interest payable by the Borrower in respect of the Advances funded by
such Fronting Advance, in which case such Fronting Fee shall be payable with respect to the period to which such interest relates.” 
 (l) Section 2.18(a) of the Credit Agreement is hereby amended by deleting the figure “$350,000,000” therein and substituting therefor the figure “$500,000,000”. 
 (m) Section 2.18 of the Credit Agreement is hereby amended by adding thereto the following new Subsection (f): 
 “(f) Notwithstanding the foregoing provisions of this Section 2.18, no Assuming Lender or Increasing Lender shall be eligible to
participate in a Commitment Increase hereunder unless such Lender (i) shall be a Qualified Lender, or (ii) shall have implemented a foreign currency fronting arrangement (either through the Fronting Bank acting in its sole discretion or
otherwise) reasonably satisfactory to the Borrower and the Administrative Agent to enable such Lender to meet its obligations hereunder to make Advances in Committed Foreign Currencies following the occurrence of any Fronting Event.”

then outstanding and owed to all Lenders (each such Lender, including any New Lender, a “Purchasing Lender”), then such Purchasing Lender, without executing an Assignment and Acceptance, shall be deemed to have purchased an
assignment of a pro rata portion of the Advances then outstanding and owed to each Lender that is not a Purchasing Lender (a “Selling Lender”) in an amount sufficient such that following the effectiveness of all such
assignments the Advances outstanding and owed to each Lender shall equal such Lender’s Pro Rata Share (calculated immediately following the effectiveness of this Amendment) of all Revolving Credit Advances then outstanding and owed to all

Agent not later than 12:00 P.M. (New York time) on the Amendment Effective Date. The Administrative Agent shall distribute on the Amendment Effective Date the proceeds of such amount to each of the Selling Lenders entitled to receive such payments
at its Applicable Lending Office. If in connection with the transactions described in this Section 2 any Lender shall incur any losses, costs or expenses of the type described in Section 9.04(c) of the Credit Agreement, then the Borrower

incurred. 
 SECTION 3. Representations and Warranties. The Borrower hereby represents and warrants that the representations and

Amendment Effective Date, before and after giving effect to this Amendment, as though made on and as of such date (except for any such representation and warranty that, by its terms, refers to a specific date other than the Amendment Effective Date,
in which case as of such specific date). 
 (c) No event shall have occurred and be continuing, or shall result from the
effectiveness of this Amendment, that constitutes a Default. 
 (d) All of the fees and expenses of the Administrative Agent
(including the reasonable fees and expenses of counsel for the Administrative Agent) due and payable on the Amendment Effective Date shall have been paid in full. 
 (e) Certified copies of (i) the resolutions of the Board of Directors, general partner or managing member, as applicable, of
(A) the Borrower approving this Amendment and the matters contemplated hereby and thereby and (B) each Guarantor approving the Consent and the matters contemplated hereby and thereby and (ii) all documents evidencing other necessary
corporate action and governmental approvals, if any, with respect to this Amendment, the Consent and the matters contemplated hereby and thereby. 
 (f) A certificate of the Secretary or an Assistant Secretary of (i) the Borrower certifying the names and true signatures of the officers of the Borrower authorized to sign this Amendment and (ii) each

Documents to “the Credit 
  

 14 

 
Agreement”, “thereunder”, “thereof” or words of like import referring to the Credit Agreement, shall mean and be a reference to the
Credit Agreement, as amended by this Amendment. 
 (b) The Credit Agreement, the Notes and each of the other Loan Documents,
as specifically amended by this Amendment, are and shall continue to be in full force and effect and are hereby in all respects ratified and confirmed. 
 (c) The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or the Administrative Agent under any of
the Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents. 
 SECTION 6. Costs and Expenses. The
Borrower agrees to pay on demand all costs and expenses of the Administrative Agent in connection with the preparation, execution, delivery and administration, modification and amendment of this Amendment and the other instruments and documents to

 Exhibit 10.10 
 SIXTH AMENDMENT TO LEASE 
 THIS SIXTH AMENDMENT TO LEASE (this “Amendment”) is
executed as of June 30, 2005, between III CENTRUM ASSOCIATES LIMITED PARTNERSHIP, a California limited partnership, and SAW ISLAND PROPERTIES, LLC, a California limited liability company, as tenants in common (“Landlord”), and NATUS
MEDICAL, INC., a California corporation (“Tenant”). 
 Recitals 
 A. Landlord and Tenant entered into a Lease Agreement dated August 24, 1998 (the “Original Lease”), which Original Lease was amended by
the Lease Termination Agreement (the “Partial Termination Agreement”) dated January 28, 1999, the First Amendment to Lease dated September 23, 1999 (the “First Amendment”), the Second Amendment to Lease dated
May 1, 2002 (the “Second Amendment”), the Third Amendment to Lease dated as of December 12, 2002 (the “Third Amendment”), the Fourth Amendment to Lease dated as of August 18, 2004 (the “Fourth
Amendment”), and the Fifth Amendment to Lease for Storage Premises dated as of November 1, 2004 (the “Fifth Amendment”). 
 B. Under the terms of the Original Lease, the First Amendment, the Second Amendment, the Third Amendment and the Fourth Amendment, Tenant leases from Landlord those certain premises containing approximately 35,149 rentable square feet of
space (the “Renewal Premises”) in portions of the Buildings (as defined in the Original Lease). Under the terms of the Fifth Amendment Tenant leases from Landlord temporary storage space (the “Storage Space”). The Premises are
located at the following addresses: 1501, 1541, 1547, 1549 and 1559 Industrial Road, San Carlos, California. The Original Lease as amended by the Partial Termination Agreement, the First Amendment, the Second Amendment, the Third Amendment, the
Fourth Amendment and the Fifth Amendment is herein referred to as the “Existing Lease”. 
 C. The Term of the Existing Lease for
the portion of the Premises containing approximately 26,299 rentable square feet and identified in the Third Amendment as the Renewal Premises is scheduled to expire on December 31, 2005. 
 D. The Term of the Lease for the Relocation Premises (as defined in the Fourth Amendment) containing approximately 8,850 rentable square feet is
scheduled to expire on December 31, 2006. 
 E. Under the Fifth Amendment Tenant leased the Storage Premises on a month-to-month
tenancy. Tenant has vacated the Storage Premises, and the tenancy for the Storage Premises has terminated. 
 F. Landlord and Tenant desire
to amend the Existing Lease to (i) extend the Term for both the Renewal Premises and the Relocation Premises to expire on June 30, 2010, (ii) amend the amount of Base Rent payable by Tenant, (iii) provide Tenant with an
Alterations Allowance (as defined below), and (iv) for other purposes, all as set forth below. 
  

 1 

 NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants contained herein, and
for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree that the Lease is amended as follows: 
 1. Definitions. Except as otherwise expressly provided herein to the contrary, all capitalized terms used in this Amendment shall have the same meanings given such terms in the Existing Lease. As amended by
this Amendment, the term “Premises” shall mean the Renewal Premises and the Relocation Premises, combined. As amended by this Amendment, the Existing Lease is herein referred to as the “Lease”. 
 2. Extension of Term. The Term of the Lease for the Premises is hereby extended to expire on June 30, 2010 (the “New Expiration
Date”). Tenant has no right to extend the Term of the Lease beyond the New Expiration Date. 
 3. Monthly Base Rent. The amount
of Base Rent payable by Tenant under the Existing Lease for the Premises is hereby amended. Commencing July 1, 2005, and continuing through the New Expiration Date, Tenant shall pay to Landlord the following monthly Base Rent for the Premises:

  

			
	 Months:
	  	 Monthly Base Rent:

	July 1, 2005 – June 30, 2006:	  	$31,634.10 per month ($0.90/s.f./mo.)
	July 1, 2006 – June 30, 2007:	  	$33,391.50 per month ($0.95/s.f./mo.)
	July 1, 2007 – June 30, 2008:	  	$35,149.00 per month ($1.00/s.f./mo.)
	July 1, 2008 – June 30, 2009:	  	$36,906.45 per month ($1.05/s.f./mo.)
	July 1, 2009 – June 30, 2010:	  	$38,663.90 per month ($1.10/s.f./mo.)

 4. Condition of Premises. Tenant has been leasing the Premises under the provisions of the
Existing Lease. Tenant shall take the Premises in their existing “AS IS” condition. Landlord shall not be obligated to construct any leasehold in the Premises, or to pay for the costs of any leasehold improvements in connection with this
Amendment. 
 5. “Eyebrow” Sign. So long as Natus Medical, Inc. (i) has not assigned this Lease or sublet any of the
Premises (it being intended that all rights pursuant to this provision are and shall be personal to the original Tenant under this Lease and shall not be transferable or exercisable for the benefit of any Transferee), (ii) leases and occupies
at least twenty-five thousand (25,000) rentable square feet of space in the Project, and (iii) is not in default under this Lease beyond any applicable notice and cure periods, then Natus Medical, Inc, shall have the right to install and
maintain in a first class condition, for no additional rent, a non-electric, unlighted “eyebrow” sign (“Tenant’s Sign”) containing only Tenant’s name “Natus” on the Building located at 1541 1ndustrial Road
(the “Sign Building”) under the following terms and conditions: 
 a) Tenant’s Sign shall be board mounted by Tenant, at
Tenant’s sole cost and expense, on the exterior parapet wall of such Sign Building, facing Highway 101, in the location shown on Exhibit A-1 attached hereto. 
  

 2 

 b) The size of Tenant’s Sign shall be approximately two (2) feet high and eight (8) feet
wide. Tenant’s Sign shall be (i) subject to review and approval by Landlord, in Landlord’s sole discretion, with respect to the size, design, material, color, method of attachment to the Sign Building and all other aspects of the
proposed sign, (ii) subject to all governmental requirements for any separate signage application, (iii) installed only after Tenant obtains all necessary permits and approvals from the applicable authorities and organizations, including
the City of San Carlos, California, and (iv) installed and maintained at Tenant’s sole cost and expense (including, without limitation, the cost of obtaining all permits and other governmental approval) in accordance with all applicable
Laws. 
 c) Tenant shall install Tenant’s Sign in a good and workmanlike manner in accordance with plans approved by Landlord, using a
contractor approved by Landlord. In installing and maintaining Tenant’s Sign, Tenant and Tenant’s contractor shall not affect the watertight integrity of the Sign Building. 
 d) Throughout the Term of the Lease Tenant shall not make any change or changes to Tenant’s Sign without the prior written consent of Landlord, which
consent may be denied or conditioned in Landlord’s sole discretion. Tenant shall be responsible for all costs and expenses of Tenant’s Sign, including costs and expenses of construction, installation and maintenance of Tenant’s Sign,
processing governmental applications, and obtaining any permits, damage to Tenant’s Sign, damage caused by Tenant’s Sign to the Sign Building, or otherwise, and removal of Tenant’s Sign at the expiration or termination of this Lease.

 e) At the expiration or termination of this Lease Tenant shall remove Tenant’s Sign. If Tenant fails to remove Tenant’s Sign, and
to repair any damage to the exterior of the Sign Building within fifteen (15) days after the expiration or termination of this Lease, then Landlord shall have the right to do so at Tenant’s expense, and Tenant agrees to pay to Landlord,
within thirty (30) days after Tenant’s receipt of Landlord invoices therefor, the costs of such removal and repair, plus fifteen percent (15%) of such costs as Landlord’s fee for coordinating and supervising any such removal and
