 Exhibit 4.1 
  

 
 FS INVESTMENT CORPORATION DISTRIBUTION REINVESTMENT PLAN 

FS Investment Corporation, a Maryland corporation (the “Company”), hereby adopts the following plan (the
“Plan”) with respect to cash dividends or distributions (each, a “Distribution”) declared by its Board of Directors (the “Board of Directors”) on shares of its
common stock, par value $0.001 per share (the “Common Stock”): 
 1. Unless a stockholder
specifically elects to receive cash in accordance with the Plan, all Distributions hereafter declared by the Board of Directors shall be payable in shares of Common Stock, and no action shall be required on such stockholder’s part to receive a
Distribution in shares of Common Stock. DST Systems, Inc., the plan administrator and the Company’s transfer agent and registrar (collectively the “Plan Administrator”), will establish an account for shares of Common
Stock received pursuant to the Plan for each stockholder who has not affirmatively elected to receive Distributions in cash (each a “Participant”). The Plan Administrator may hold each Participant’s shares of Common
Stock, together with the shares of Common Stock of other Participants in the Plan Administrator’s name or that of its nominee. 

2. Such Distributions shall be payable on such date or dates (each, a “Payment Date”) as may be fixed from time
to time by the Board of Directors to stockholders of record at the close of business on the record date(s) established by the Board of Directors for such Distribution. 

3. With respect to each Distribution pursuant to the Plan, the Company reserves the right to either issue new shares of Common Stock or
purchase shares of Common Stock in the open market for the accounts of Participants in connection with implementation of the Plan. Unless the Company, in its sole discretion, otherwise directs the Plan Administrator: 

(A) if the Market Price (as defined below) is equal to or greater than NAV (as defined below), then the Company shall issue shares of Common
Stock at the greater of (i) NAV or (ii) 95% of the Market Price; or 
 (B) if the Market Price is less than the NAV, then, in the
sole discretion of the Company, (i) shares of Common Stock shall be purchased in open market transactions for the accounts of Participants to the extent practicable, or (ii) the Company shall issue shares of Common Stock at NAV. 

The number of shares of Common Stock to be issued to a Participant is determined by dividing the total dollar amount of the Distribution payable to the
Participant by the price at which the Company issues such shares of Common Stock pursuant to 3.(A)(i), 3.(A)(ii) or 3.(B)(ii), as applicable. Shares of Common Stock purchased in open market transactions pursuant to 3.(B)(i) will be allocated to a
Participant based on the average purchase price, excluding any brokerage charges or other charges, of all shares of Common Stock purchased in the open market with respect to such Distribution. “Market Price” means the
market price per share of the Common Stock at the close of regular trading on the New York Stock Exchange or any other exchange or inter-dealer quotation system that represents the principal trading market for the shares of Common Stock (the
“Principal Trading Market”) on the Payment Date, or if no sale is reported for such day, the average of the reported bid and asked prices. “NAV” means the net asset value per share (as
estimated in good faith by the Company and rounded up to the nearest whole cent) of Common Stock on the Payment Date. 
 4. A
stockholder may, however, affirmatively elect to receive such stockholder’s Distributions in cash. Except as may otherwise be permitted by the Company in its sole discretion, the election will be effective immediately if such stockholder
notifies the Plan Administrator in writing not less than 10 days prior to the record date fixed by the Board of Directors for the next Distribution; otherwise, such election will be effective only with respect to any subsequent
Distribution. Such election shall remain in effect until the stockholder shall notify the Plan Administrator in writing of such stockholder’s withdrawal of the election, which withdrawal will be effective immediately if such stockholder
notifies the Plan Administrator in writing not less than 10 days prior to the record date fixed by the Board of Directors for the next Distribution; otherwise, such withdrawal will be effective only with respect to any subsequent Distribution. 

 5. The Plan Administrator will confirm to each Participant each issuance or acquisition made
pursuant to the Plan on such Participant’s behalf as soon as practicable, but not later than 30 days after the date thereof. Although each Participant may from time to time have a fractional interest (computed to three decimal places) in a
share of Common Stock of the Company, no certificates for a fractional share will be issued. However, Distributions on fractional shares will be credited to each Participant’s account. 

6. The Plan Administrator or another agent designated by the Company will forward to each Participant any proxy solicitation materials
related to the Company and each report or other communication of the Company delivered to stockholders, and will vote any shares of Common Stock held by it under the Plan in accordance with the instructions set forth on proxies returned to the
Company by Participants. 
 7. In the event that the Company makes available to its stockholders rights to purchase additional shares
of Common Stock or other securities, the shares of Common Stock held by the Plan Administrator for each Participant under the Plan will be added to any other shares of Common Stock held by the Participant in calculating the number of rights to be
issued to the Participant. 
 8. There will be no brokerage charges or other sales charges on newly-issued shares of Common Stock
acquired by a stockholder under the Plan. The Plan Administrator’s service fee, if any, and expenses for administering the Plan will be paid for by the Company. If a Participant elects by written notice to the Plan Administrator to have the
Plan Administrator sell part or all of the shares of Common Stock held by the Plan Administrator in the Participant’s account and remit the proceeds to the Participant, whether upon termination of the Plan by the Company, termination by a
Participant of such Participant’s account under the Plan or otherwise, the Plan Administrator shall be authorized to deduct from the proceeds a $20.00 transaction fee for each transaction requested by a Participant, plus any applicable
brokerage commission. 
 9. The Plan Administrator will be responsible for generating or providing a Form 1099-DIV or any related tax
forms associated with any Distributions that are reinvested or paid out. 
 10. Each Participant may terminate such Participant’s
account under the Plan by so notifying the Plan Administrator in writing. Such termination will be effective immediately if the Participant’s notice is received by the Plan Administrator not less than 10 days prior to the record date fixed
by the Board of Directors for the next Distribution; otherwise, such termination will be effective only with respect to any subsequent Distribution. The Plan may be terminated by the Company upon notice in writing mailed to each Participant at
least 30 days prior to any record date for the payment of any Distribution by the Company; if such notice is mailed fewer than 30 days prior to such record date, such termination will be effective immediately following the Payment Date for such
Distribution. Upon any termination of the Plan by the Company or by a Participant of such Participant’s account under the Plan, the Plan Administrator will cause whole shares of Common Stock held for the Participant under the Plan to be
credited to the Participant in book-entry form with the Company’s transfer agent and a cash adjustment for any fractional shares to be paid to the Participant at the market price per share of Common Stock at the close of regular trading on the
Principal Trading Market on the date of such termination. If no sale is reported on the Principal Trading Market on the date of such termination, then the market price for the purpose of the payment of the cash adjustment for any fractional shares
shall be the average of their electronically-reported bid and asked prices on the Principal Trading Market on such termination date. 

11. These terms and conditions may be amended or supplemented by the Company at any time but, except when necessary or appropriate to
comply with applicable law or the rules, regulations or policies of the Securities and Exchange Commission or any other regulatory authority, only by mailing to each Participant appropriate written notice at least 30 days prior to the effective date
thereof. The amendment or supplement shall be deemed to be accepted by each Participant unless, prior to the effective date thereof, the Plan Administrator receives written notice of the termination of such Participant’s account under the
Plan. Any such amendment or supplement may include an appointment by the Plan Administrator in its place and stead of a successor agent under these terms and conditions, with full power and authority to perform all or any of the acts to be
performed by the Plan Administrator under the terms and conditions agreed upon by the Company. Upon any such appointment of any agent for the purpose of receiving Distributions, the Company shall be authorized to pay to such successor agent,
for each Participant’s account, all Distributions payable on shares of Common Stock held in the Participant’s name or under the Plan for retention or application by such successor agent as provided in these terms and conditions. 

12. The Plan Administrator will at all times act in good faith and use its best efforts within reasonable limits to ensure its full and
timely performance of all services to be performed by it under the Plan and to comply with applicable law, but assumes no responsibility and shall not be liable for loss or damage due to errors unless such error is caused by the Plan
Administrator’s negligence, bad faith, or willful misconduct or that of its employees or agents. 

 13. These terms and conditions of the Plan shall be governed by and construed in accordance
with the laws of the State of Maryland, without regard to any conflict of laws principals or rules thereof, to the extent such principals would require or permit the application of the laws of another jurisdiction, and the Investment Company Act of
1940, as amended (the “1940 Act”). In the event of a conflict, the applicable provisions of the 1940 Act shall control.

 Exhibit 10.1 

FIRST AMENDMENT TO LEASE 

THIS FIRST AMENDMENT TO LEASE (this “Amendment”)
is dated as of May 19, 2014 and entered into by and between DWF III GATEWAY, LLC, a Delaware limited liability company (“Landlord”), and PUMA BIOTECHNOLOGY, INC., a
Delaware corporation (“Tenant”). 
 R E C I T
A L S 
 Landlord and Tenant are parties to that certain Office Lease dated as of
May 16, 2012 (the “Original Lease”), pursuant to which Tenant leases certain office premises consisting of approximately 9,560 rentable square feet known as Suite 275 (the “Original Premises”) located within
that certain office building known as “701 Gateway”, with an address of 701 Gateway Boulevard, South San Francisco, California (the “Building”). 

Tenant desires to expand the Original Premises by leasing additional space within the Building containing approximately 7,152 rentable square
feet known as Suite 250 and as more particularly shown on Exhibit A hereto (the “Expansion Premises”). 

Accordingly, Landlord and Tenant now desire to amend the Original Lease to, among other things, provide for Tenant’s lease of the
Expansion Premises, all upon and subject to the terms, covenants and conditions hereinafter set forth. 
 A G
R E E M E N T 

NOW THEREFORE, in consideration of the agreements of Landlord and Tenant herein contained and other valuable
consideration, the receipt and adequacy of which are hereby acknowledged, Landlord and Tenant hereby agree as follows: 
  

	1.	RECITALS 

 Landlord and Tenant acknowledge and agree the above recitals
are true and correct and are hereby incorporated herein as though set forth in full. 
  

	2.	DEFINITIONS 

 As of the date hereof, unless the context clearly indicates
otherwise, all references to “the Lease” or “this Lease” in the Lease or in this Amendment shall be deemed to refer to the Original Lease, as amended by this Amendment. Capitalized terms used but not defined herein shall have the
meanings ascribed to them in the Original Lease unless context clearly indicates otherwise. 
  

	3.	LEASE OF EXPANSION PREMISES 

(a) Commencing as of the date (the “Expansion Date”) that is the later to occur of (i) December 1, 2014,
(ii) the Substantial Completion of the Tenant Improvements, as such terms are defined in Exhibit B hereto, and (iii) the date that Landlord shall have delivered the Expansion Premises to Tenant vacant and free of any other
possessory rights with the Tenant Improvements Substantially Complete or the date the foregoing would have occurred but for any Tenant Delays, all references in the Original Lease to the “Leased Premises” shall be deemed to refer to both
the Original Premises and the Expansion Premises. 

  
 1 

 (b) The parties anticipate the Expansion Date to be on or about December 1, 2014 (the
“Estimated Expansion Date”), subject to Force Majeure Delays and Tenant Delays (as such terms are defined in Exhibit B). If, for any reason whatsoever, Landlord has failed to deliver the Expansion Premises to
Tenant by the Estimated Expansion Date, then this Amendment shall not be void or voidable, nor shall Landlord be liable to Tenant for any loss or damage resulting therefrom. 

(c) Landlord will allow Tenant to have access to the Expansion Premises for the fifteen (15) days prior to the Substantial Completion of
the Tenant Improvements. The period of time prior to the Expansion Date during which Tenant may have early access and use of the Expansion Premises under this Section 3(c) shall be referred to herein as the “Early Access
Period.” Tenant agrees that it shall not in any way interfere with the progress of the Tenant Improvements by such access. Should such access prove an impediment to the progress of the Tenant Improvements, in Landlord’s judgment, then
Landlord may demand that Tenant forthwith vacate the Expansion Premises until such time as the Tenant Improvements are complete, and Tenant shall immediately comply with this demand. During the Early Access Period, Tenant shall comply with all terms
and conditions of the Lease, except that no Minimum Monthly Rent shall be payable for the Expansion Premises during such period. As a condition to entering the Expansion Premises during the Early Access Period, Tenant shall provide Landlord with
certificates of insurance that Tenant is required to provide Landlord during the Term of the Lease. 
 (d) Promptly following the Expansion
Date, Landlord and Tenant shall execute an Expansion Date Memorandum in the form attached hereto as Exhibit C, wherein the parties shall acknowledge the Expansion Date. 

 

	4.	TERM 

 The parties acknowledge that the Term of the Original Lease is
scheduled to expire on October 31, 2019 (the “Original Term Expiration Date”). Notwithstanding the foregoing, Landlord and Tenant agree that the Term is hereby extended for a period of twenty-four (24) months, such that
the Term shall expire as of October 31, 2021, unless sooner terminated in accordance with the terms and conditions of the Lease. 

  
 2 

	5.	MINIMUM MONTHLY RENT 

 (a) The Minimum
Monthly Rent payable for the Original Premises shall continue to be payable in accordance with the terms of the Original Lease, through the Original Term Expiration Date. Commencing on the day immediately following the Original Term Expiration Date,
the Minimum Monthly Rent payable for the Original Premises shall be payable in accordance with the following schedule: 
  

									
	 Period
	  	Sq. Ft.	 	  	Minimum Monthly Rent	 
	 November 1, 2019 - October 31, 2020
	  	 	9,560	  	  	$	35,464.51	  
	 November 1, 2020 - October 31, 2021
	  	 	9,560	  	  	$	36,528.45	  

 (b) In addition to the Minimum Monthly Rent payable for the Original Premises, effective as of the Expansion
Date and continuing thereafter through the remainder of the Term, Tenant shall pay Minimum Monthly Rent for the Expansion Premises in accordance with the following schedule: 
  

									
	 Period (Months)
	  	Sq. Ft.	 	  	Minimum Monthly Rent	 
	 1 - 12
	  	 	7,152	  	  	$	22,886.40	  
	 13 - 24
	  	 	7,152	  	  	$	23,572.99	  
	 25 - 36
	  	 	7,152	  	  	$	24,280.18	  
	 37 - 48
	  	 	7,152	  	  	$	25,008.58	  
	 49 - 60
	  	 	7,152	  	  	$	25,758.84	  
	 61 - 72
	  	 	7,152	  	  	$	26,531.61	  
	 73 - October 31, 2021
	  	 	7,152	  	  	$	27,327.56	  

 Notwithstanding the foregoing, provided that Tenant is not in default (beyond all applicable notice and cure
periods), then Tenant shall be excused from the obligation of paying the Minimum Monthly Rent (but not any other amounts) due hereunder for the Expansion Premises for the first five (5) full calendar months following the Expansion Date, in the
aggregate amount of $114,432.00 (the “Excused Minimum Monthly Rent”). However, should Tenant default (beyond all applicable notice and cure periods) such that Landlord properly exercises Landlord’s remedies pursuant to Article
25 of the Original Lease, then the Excused Minimum Monthly Rent shall no longer be excused and shall become an obligation of Tenant hereunder, and Landlord shall be entitled to seek recovery of the Excused Minimum Monthly Rent as part of the damages
to which Landlord is otherwise entitled pursuant to the terms of the Lease. 
 Landlord shall have the right in its sole and absolute
discretion to cancel Tenant’s right to all or any portion of the Excused Minimum Monthly Rent upon written notice to Tenant prior to the date Tenant has used or applied all of the Excused Minimum Monthly Rent, provided that within ten
(10) days after delivery of such notice, Landlord pays Tenant for the exact same amount of the Excused Minimum Monthly Rent that Landlord elects to cancel (the “Abated Minimum Monthly Rent Cancellation Payment”). Landlord may
only cancel the Excused Minimum Monthly Rent remaining as of the date of Landlord’s notice to cancel the Excused Minimum Monthly Rent. Tenant shall make payments of Minimum Monthly Rent in the amount of $22,886.40 for each month covered by the
Abated Minimum Monthly Rent Cancellation Payment. If Landlord exercises its right to pay the Abated Minimum Monthly Rent Cancellation Payment as provided above, Landlord shall prepare and deliver to Tenant an amendment to the Lease reflecting the
exercise of such right by Landlord and Tenant shall execute such amendment within five (5) business days after request by Landlord. 

  
 3 

	6.	ADDITIONAL RENT 

 As to the Expansion Premises only,
(i) the Base Year for Base Year Operating Costs shall be the calendar year 2015, (ii) the Base Year for Base Taxes shall be the real estate fiscal year 2014/2015, and (iii) Tenant’s Proportionate Share shall be 4.20%. For the
avoidance of doubt, the Base Years and Tenant’s Proportionate Share as to the Original Premises shall remain unchanged and are acknowledged to be the calendar year 2012 for Base Year Operating Costs, the real estate fiscal year 2012/2013 for
Base Taxes, and 5.61%, respectively. 
  

	7.	CONDITION OF PREMISES 

 (a) Tenant
acknowledges that it has been, and continues to be, in possession of the Original Premises, is familiar with the condition of the Original Premises and continues to occupy the Original Premises in its “as is” condition, with all faults,
without any representation, warranty or improvement by Landlord of any kind whatsoever, other than as expressly set forth in the Original Lease. 

(b) By its execution hereof, Tenant acknowledges that it had the opportunity to fully inspect the Expansion Premises. Subject to
Landlord’s obligations as set forth in Exhibit B hereto, Tenant accepts the Expansion Premises, subject to the completion of the Tenant Improvements, as suitable for Tenant’s intended use, “as
is”, and without representation or warranty by Landlord of any kind whatsoever (other than Landlord’s obligation to complete the Tenant Improvements). Notwithstanding the foregoing, the representations and warranties contained in
Section 3.6 of the Original Lease are hereby made by Landlord, as to the Expansion Premises, as of the date of this Amendment. 
 (c)
Neither the Original Premises nor the Expansion Premises has undergone an inspection by a Certified Access Specialist (CASp). The foregoing statement is included in this Amendment solely for the purpose of complying with California Civil Code
Section 1938 and shall not in any manner affect Landlord’s and Tenant’s respective responsibilities for compliance with construction-related accessibility standards as provided in the Original Lease. 

 

	8.	PARKING 

 Effective as of the Expansion Date and continuing through the
remainder of the Term, Tenant’s Parking Allocation shall be fifty-four (54) parking spaces. 
  

	9.	SERVICE AND EQUIPMENT 

 Section 11.11
of the Original Lease is hereby amended by adding the following additional language to the end of the paragraph: “Without limiting the generality of the foregoing, in the event Tenant uses utilities at the Leased Premises in excess of normal
office use (as contemplated under the Lease), then Landlord may cause a separate meter to be installed in or for the Leased Premises, and the cost of any such meters (including, without limitation, the cost of any installation and maintenance) shall
be paid by Tenant.” 

  
 4 

	10.	TEMPORARY SPACE 

 At the request of Tenant, the parties
have agreed that Tenant shall lease and occupy on a temporary basis approximately 6,923 square feet of Rentable Area in Suite 100 of the Building (the “Temporary Space”), as generally outlined in Exhibit D attached
hereto. Accordingly, Landlord leases to Tenant and Tenant leases from Landlord the Temporary Space for a term commencing on the date that Landlord delivers possession of the Temporary Space (the “Temporary Space Commencement Date”)
and expiring on the date which is five (5) business days following the Expansion Date (the “Temporary Space Term”). Landlord shall deliver the Temporary Space to Tenant on or before July 1, 2014. If Landlord fails to
deliver the Temporary Space to Tenant on or before July 1, 2014, then Tenant may terminate this Amendment, in which event this Amendment shall be null and void and of no force or effect by written notice delivered to Landlord at any time after
July 1, 2014 and prior to the date that the Temporary Space is delivered to Tenant. The foregoing right to terminate shall be Tenant’s sole remedy for Landlord’s failure to deliver the Temporary Space to Tenant on or before
July 1, 2014 and Landlord shall not be liable to Tenant for any loss or damage resulting therefrom. The lease of the Temporary Space shall be subject to all other terms and provisions of the Lease, except as provided in this Section 10.
During the Temporary Space Term and as applicable to the lease of the Temporary Space, all references in the Lease to the Leased Premises shall include the Temporary Space. 

(a) Rent and Utility Costs for Temporary Space. During the Temporary Space Term, Tenant shall pay Minimum Monthly Rent for the
Temporary Space in the amount of $13,846.00. Tenant shall not be obligated to pay Operating Costs, Taxes or standard building services for the Temporary Space. However, Tenant shall pay for costs for usage of the HVAC outside of the Climate Control
Hours (as defined in Section 11.1 of the Original Lease) and for any Excess Utility Costs (as defined in Section 11.11 of the Original Lease) respecting the Temporary Space. Tenant shall make such payment to Landlord within fifteen
(15) days after request by Landlord each month. Tenant shall be responsible for arranging and paying for all of its telephone and telecommunication services for the Temporary Space, subject to Tenant’s right to utilize a portion of
Landlord’s Allowance for such cabling costs as provided in Exhibit B. 
 (b) Condition of Temporary Space.
Tenant shall accept possession of the Temporary Space in its current “AS IS” condition, without the construction or installation by Landlord of any improvements, furnishings or equipment of any kind, without any allowances, credits or free
rent and without any representation or warranty, expressed or implied, by Landlord or any of its agents concerning the condition or suitability of the Temporary Space. Any work and allowance including, without limitation, Landlord’s Allowance,
to be performed or provided by Landlord in connection with the Original Premises and/or the Expansion Premises will not be applicable for the lease of the Temporary Space (subject to Tenant’s right to utilize a portion of Landlord’s
Allowance for cabling costs as provided in Exhibit B). In addition, during the Temporary Space Term Tenant shall be entitled to use Landlord’s furniture located in the Temporary Space as described in Exhibit E hereto
(the “Temporary Space Furniture”). Tenant shall notify Landlord in writing within five (5) business days after the date of delivery of the Temporary Space to Tenant of any Temporary Space Furniture listed in Exhibit
E that is missing. Landlord shall not be required to replace any missing Temporary Space Furniture and the reference to the Temporary Space Furniture shall mean the furniture actually located in the Temporary Space when the

  
 5 

 
Temporary Space is delivered to Tenant. Landlord makes no representation or warranty whatsoever with respect to the condition of the Temporary Space Furniture or its suitability for Tenant’s
use, and any such use to be on an “as-is” basis. Tenant shall be responsible for any damage to the Temporary Space Furniture caused by Tenant or any of its employees, agents or contractors. Such furniture shall remain the property of
Landlord. 
 (c) No Alterations. Tenant shall not construct any improvements or alterations in the Temporary Space, except for
the installation of telephone and electrical lines and other minor work, all of which shall be subject to the prior written consent of Landlord and otherwise in compliance with the requirements of the Lease for the construction of alterations. The
cost to construct any improvements or alterations by Tenant in the Temporary Space shall be paid by Tenant. 
 (d) Surrender of
Temporary Space. Tenant shall vacate and surrender possession of the Temporary Space by the end of the Temporary Space Term, with time being of the essence, in broom clean condition, with all repairs and maintenance that would be required
for surrender of the Leased Premises completed and with all of Tenant’s furniture, trade fixtures, equipment and other personal property removed; provided, however, that the Temporary Space Furniture shall remain in the Temporary Space. Tenant
acknowledges that Landlord is marketing the Temporary Space for lease by others. In reliance upon Tenant’s agreement to vacate and surrender possession of the Temporary Space on time, Landlord may enter into other commitments affecting the
Temporary Space and may incur significant expenses in connection therewith, including, without limitation, brokerage commissions and fees, legal or other professional fees, the costs of space planning and the costs of construction of improvements.
Tenant acknowledges that all of said expenses, in addition to all other expenses incurred and actual and consequential damages suffered by Landlord, shall be included in measuring Landlord’s damages should Tenant fail to vacate and surrender
possession on time. 
 (e) Temporary Space Holdover. If Tenant does not vacate and surrender possession of the Temporary Space
by the end of the Temporary Space Term, such hold over shall be governed by the terms of Section 33.2 of the Original Lease, as the same relates to the Temporary Space; provided nothing in this Lease shall be deemed to grant Tenant any right to
hold over in the Temporary Space beyond the end of the Temporary Space Term. 
  

	11.	FURNITURE 

 (a) Right to Use During the Term. During the
Term, Tenant shall have the right, at no cost to Tenant, to use the furniture and other personal property of Landlord in the Expansion Premises described on Exhibit F hereto (“Landlord’s Personal
Property”), subject to the terms and conditions contained in this Section 11. All right, title or interest in Landlord’s Personal Property shall be in and remain with Landlord and no right, title or interest
in Landlord’s Personal Property shall pass to Tenant other than the right to possess and use Landlord’s Personal Property during the Term of this Lease. 

(b) Tenant’s Obligations. Tenant shall: (i) at its sole expense, repair and maintain each item of Landlord’s
Personal Property in the same condition as when received, ordinary wear and tear excepted, and in compliance with all Applicable Laws and all instructions and 

  
 6 

 
recommendations as to the repair and maintenance of such item of Landlord’s Personal Property issued at any time by the vendor and/or manufacturer thereof; (ii) maintain conspicuously
on any of Landlord’s Personal Property such labels, plates, decals or other markings as Landlord may reasonably place thereon, stating that Landlord is the owner of such Landlord’s Personal Property; (iii) furnish to Landlord such
information concerning the condition, location, use and operation of Landlord’s Personal Property as Landlord reasonably may request; (iv) make no additions, alterations, modifications or improvements to any item of Landlord’s
Personal Property without Landlord’s prior written consent, which shall not be unreasonably withheld; (v) not, directly or indirectly, create, incur or permit to exist any lien, encumbrance, mortgage, pledge, attachment or security
interest on or with respect to Landlord’s Personal Property (except those of persons claiming by, through or under Landlord); and (vi) use Landlord’s Personal Property solely in the conduct of Tenant’s business and keep
Landlord’s Personal Property in the Expansion Premises. 
 (c) Disclaimer. TENANT ACKNOWLEDGES THAT LANDLORD IS NOT THE
MANUFACTURER OR SUPPLIER OF LANDLORD’S PERSONAL PROPERTY, NOR THE AGENT THEREOF, AND THAT LANDLORD MAKES NO EXPRESS OR IMPLIED REPRESENTATIONS OR WARRANTIES AS TO ANY MATTER WHATSOEVER IN CONNECTION WITH LANDLORD’S PERSONAL PROPERTY,
INCLUDING WITHOUT LIMITATION, THE MERCHANTABILITY OF LANDLORD’S PERSONAL PROPERTY, ITS FITNESS FOR A PARTICULAR PURPOSE, ITS DESIGN OR CONDITION, ITS CAPACITY OR DURABILITY, OR THE QUALITY OF THE MATERIAL OR WORKMANSHIP IN THE MANUFACTURE OR
ASSEMBLY OF LANDLORD’S PERSONAL PROPERTY. Landlord is not responsible for any repairs or service to Landlord’s Personal Property, defects therein or failures in the operation thereof. For so long as Tenant performs each and all of its
obligations under this Lease, Tenant shall be the beneficiary of, and shall be entitled to, all rights under any applicable manufacturer’s or vendor’s warranties with respect to Landlord’s Personal Property, to the extent permitted by
law. If Landlord’s Personal Property does not operate as warranted, becomes obsolete, or is unsatisfactory for any reason whatsoever, Tenant shall make all claims on account thereof solely against the manufacturer or supplier and not against
Landlord, and Tenant shall nevertheless pay all Rent payable under this Lease. Landlord shall have no liability in connection with or arising out of the ownership, leasing, furnishing, performance or use of Landlord’s Personal Property or, in
any event, any special, indirect, incidental or consequential damages of any character, including, without limitation, loss of use of production facilities or equipment, loss of profits, property damage or lost production, whether suffered by Tenant
or any third party. 
  

	12.	GENERAL PROVISIONS 

 (a) Ratification. Except
as expressly amended hereby, the Original Lease shall remain unmodified and in full force and effect. As modified hereby, the Original Lease is hereby ratified and confirmed in all respects. In the event of any inconsistencies between the terms of
this Amendment and the Original Lease, the terms of this Amendment shall prevail. 
 (b) Entire Agreement. The Original Lease
as amended hereby constitutes the entire understanding and agreement of the parties with respect to the subject matter hereof, and all prior agreements, representations, and understandings between the parties with respect to the subject

  
 7 

 
matter hereof, whether oral or written, are or should be deemed to be null and void, all of the foregoing having been merged into this Amendment. The parties acknowledge that each party and/or
its counsel have reviewed and revised this Amendment, and agree that no rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall be employed in the interpretation of this Amendment.

Amendment shall inure to the benefit of and be binding upon the Parties and their respective successors and permitted assigns with respect to the Lease.

authorized to execute and deliver this Amendment in accordance with a duly adopted resolution or other applicable authorization of said organization, and that this Amendment is binding upon said organization in accordance with its terms.

(i) Effectiveness. The parties agree that the submission of a draft or copy of this Amendment for review or signature by a party
is not intended, nor shall it constitute or be deemed, by either party to be an offer to enter into a legally binding agreement with respect to the subject matter hereof and may not be relied on for any legal or equitable rights or obligations. Any
draft or document submitted by Landlord or its agents to Tenant shall not constitute a reservation of or option or offer in favor of Tenant. The parties shall be legally bound with respect to the subject matter hereof pursuant to the terms of this
Amendment only if, as and when all the parties have executed and delivered this Amendment to each other. Prior to the complete execution and delivery of this Amendment by all parties, each party shall be free to negotiate the form and terms of this

period, then the Tenant Delay shall not be deemed to have commenced until Landlord notifies Tenant of the Tenant Delay.

accordance with the Construction Plans.

 B-4 

 
in the Premises, necessary to enable the architect, designer or contractor to prepare a preliminary plans for the Tenant Improvements containing all demising walls, corridors, entrances, exits,
doors, interior partitions, and the locations of all offices, conference rooms, and other rooms and layout, all of which shall be typical interior office improvements (the “Information”). Landlord shall be entitled to rely upon all
Information, plans, drawings and information supplied by or for Tenant in preparing the preliminary plans. By the later of (a) June 19, 2014 or (b) within five (5) days after receipt of the preliminary plans, Tenant shall notify
Landlord in writing that (i) Tenant has approved such preliminary plans, which approval shall not be unreasonably withheld, conditioned or delayed; or (ii) Tenant disapproves such preliminary plans, including the particular instances
specified by Tenant in such notice (and the specific changes requested by Tenant), but such disapproval shall constitute a Tenant Delay unless the preliminary plans are inconsistent with the Information. Tenant shall not unreasonably withhold its
approval to the preliminary plans. The failure of Tenant to provide such written notice within said five (5) day period shall be deemed as approval by Tenant of such preliminary plans. The preliminary plans approved by the parties as provided
above shall be referred to as the “Preliminary Plans.” 
 4.2 Construction Plans. After approval of the Preliminary
Plans, Landlord shall cause to be prepared Construction Plans for the construction of the Tenant Improvements and deliver the same to Tenant as soon as reasonably possible. Within five (5) days after receipt of the Construction Plans, Tenant
shall notify Landlord in writing that (i) Tenant approved the Construction Plans, which approval shall not be unreasonably withheld, conditioned or delayed; or (ii) Tenant disapproves the Construction Plans, including the particular
instances specified by Tenant in such notice (and the specific changes requested by Tenant), but such disapproval shall constitute a Tenant Delay unless the Construction Plans are inconsistent with the Preliminary Plans. The failure of Tenant to
provide such written notice within said five (5) day period shall be deemed as approval by Tenant of such plans. 
 5. Approval of
the Construction Budget. After approval of the Construction Plans by Landlord and Tenant as provided above, Landlord shall prepare the Construction Budget for the Construction Costs and shall deliver a copy of such Construction Budget to Tenant.
The Construction Budget shall not be subject to the prior written approval of Tenant, unless the estimated Construction Costs exceed the amount of Landlord’s Allowance. If the Construction Budget reflects Construction Costs in excess of
Landlord’s Allowance, it shall be subject to Tenant’s review and approval, which shall not be unreasonably withheld, conditioned or delayed. Tenant shall notify Landlord in writing within five (5) days after receipt of the
Construction Budget that (a) Tenant approves the Construction Budget, or (b) that Tenant disapproves of the Construction Budget because it varies from the Construction Plans or contains details or items not specifically addressed in the
Construction Plans. The failure of Tenant to provide such written notice within said five (5) day period shall be deemed an approval by Tenant. 

6. Building Permits. After approval by Landlord and Tenant of the Construction Plans and Construction Budget as provided above,
Landlord or its contractor shall submit the Construction Plans to the appropriate governmental body for plan checking and a building permit. Landlord, with Tenant’s cooperation, shall cause to be made any change in the Construction Plans
necessary to obtain the building permit and to the extent the aggregate amount of the Construction Costs exceeds the amount of Landlord’s Allowance, Tenant shall be responsible for such additional costs, notwithstanding the amount previously
specified in the Construction Budget approved by Landlord and Tenant. 
 7. Changes. Any changes in the Construction Plans or
Construction Budget, including, without limitation, any changes required by any applicable law, rule, regulation or ordinance, shall require the prior written consent of Landlord in its reasonable discretion. Any changes requested by Tenant and
approved by Landlord shall be prepared by Landlord’s architect, engineer or contractor. The cost of such changes, including the cost to revise the Construction Plans, obtain any additional permits and construct any additional improvements
required as a result thereof, and the cost for materials and labor, and all 

  
 B-5 

 
other additional costs incurred by Landlord from resulting delays in completing the Tenant Improvements, shall be paid out of Landlord’s Allowance (only to the extent funds are available and
not committed for payment of other Construction Costs). If such costs for changes exceed the Landlord’s Allowance, such excess costs shall be paid by Tenant, at its sole cost and expense, to Landlord within ten (10) days after
Tenant’s receipt of notice from Landlord, together with reasonable supporting documents reflecting such increased costs. If Landlord does not receive such payment within said ten (10) day period, Landlord shall have the right, in addition
to any other rights or remedies available under the Lease, at law or in equity, to (i) discontinue all or any portion of the work until it receives said payment; (ii) proceed with the other work not affected by such change until such
payment is received; (iii) proceed with the work contemplated with such change; or (iv) proceed with the work without making such change; in which case the commencement or completion of such work shall not be deemed a waiver of
Tenant’s obligation to pay for same or any additional costs or expenses incurred as a result thereof. The cost of a change order incurred as a result thereof shall be determined by Landlord’s architect, which determination shall be binding
upon the parties. 
 8. Payment. Landlord shall pay for the Construction Costs for the Tenant Improvements, not to exceed the amount
of Landlord’s Allowance. Tenant acknowledges and agrees that it shall be responsible for payment of all Construction Costs in excess of Landlord’s Allowance and shall pay to Landlord within thirty (30) days after request from Landlord
the amount of such excess Construction Costs. 
 9. Construction Management Fee. Landlord, or an agent of Landlord, shall provide
project management services in connection with the construction of the Tenant Improvements. Such project management services shall be performed, at Tenant’s cost, for a fee (the “Construction Management Fee”) equal to three
percent (3%) of the amount of the Construction Costs for the Tenant Improvements, but in no event more than $3,500.00. Landlord shall be entitled to use the Landlord’s Allowance for payment of such Construction Management Fee on a monthly
basis. If there are insufficient funds available in Landlord’s Allowance to pay for the Construction Management Fee, Tenant shall pay for the fee within ten (10) days after request by Landlord. 

10. Access. From and after the mutual execution and delivery of the Amendment, Landlord and Landlord’s employees, agents and
contractors shall be granted access to the Original Premises at reasonable times to the extent necessary in connection with the construction of the Tenant Improvements within the Expansion Premises. Landlord shall use commercially reasonable efforts
to minimize disruption to the use of the Original Premises during the construction of the Tenant Improvements. Tenant acknowledges that during construction of the Tenant Improvements that the areas of the Original Premises then being occupied by
Tenant may not be separated from the work being performed by Landlord and Landlord’s contractors and that, as a result of Landlord’s construction of the Tenant Improvements, there may be construction noise, dust and related inconveniences
to Tenant’s use of the Original Premises. Tenant hereby acknowledges and agrees that it shall not be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of the Original Premises by Landlord and
Landlord’s employees, agents and contractors nor their activities within the Original Premises in connection with construction of the Tenant Improvements. Tenant hereby acknowledges and agrees that neither the access to the Original Premises by
Landlord and Landlord’s employees, agents and contractors nor their activities within the Original Premises in connection with construction of the Tenant Improvements shall constitute nor be deemed to constitute a denial of Tenant’s access
to, or interference with Tenant’s use of, the Premises nor shall either constitute grounds for an abatement of Rent payable under the Lease. 

11. Tenant’s Representative. Tenant hereby authorizes Charles Eyler located at Puma Biotechnology, Inc., 10880 Wilshire Blvd.,
Suite 1250, Los Angeles, CA 90024, as Tenant’s representative to act on its behalf and represents its interests with respect to the construction of Tenant Improvements, and to make decisions binding upon Tenant with respect to such matters.

  
 B-6 

 12. Tenant’s Lease Default. Notwithstanding any provision to the contrary contained
in the Lease or this Exhibit, if an event of default (beyond all applicable notice and cure periods) by Tenant under the Lease or this Exhibit, has occurred at any time on or before the Substantial Completion of the Tenant Improvements, then
(i) in addition to all other rights and remedies granted to Landlord pursuant to the Lease and/or this Exhibit, Landlord shall have the right to cease the construction of the Tenant Improvements (in which case, Tenant shall be responsible for
any delay in the Substantial Completion of the Tenant Improvements caused by such work stoppage), and (ii) all other obligations of Landlord under the terms of this Exhibit shall be forgiven until such time as such default is cured pursuant to
the terms of the Lease.
