3.2 This Sublease will expire on:

a) September 1, 2011 (“Expiration Date”), unless Subtenant requests for an extension to the Sublease for another six (6) months in writing to FibroGen no later than thirty (30) days in advance of the Expiration Date.

c) any strikes, boycotts or like obstructive actions by employees or labor organizations and which are beyond the control of FibroGen and which cannot be reasonably overcome; or

4. RENT AND OTHER AMOUNTS.

4.1 Subtenant shall pay a monthly rent (“Rent”) to FibroGen for the Subleased Premises according to the following schedule:

Months	Rent/Sq.Ft./Mo.		Total Sq. Ft.	Amount/Mo.

b) Those services specified in Paragraph 5.1 below.

4.2 All Rent shall be payable without deduction or offset in advance on the first day of each month during the Term provided however, the first month’s Rent for the Subleased Premises will be paid to FibroGen no later than seven (7) days prior to the Sublease Commencement Date.

Rent shall be payable to FibroGen at the address stated herein or at such other address as FibroGen may from time to time designate in writing.

4.3 Except as expressly herein provided, any amount due FibroGen but not paid when due shall bear interest at the lesser of ten percent (10%) per annum or the maximum rate then allowable by law from the date due. Payment of such interest shall not excuse or cure any default by Subtenant under this Sublease, provided, however, that interest shall not be payable on late charges incurred by Subtenant nor on any amounts upon which late charges are paid by Subtenant.

5. SERVICES

5.1 Included lab services are limited to the systems that are in place on the Sublease Commencement Date to supply de-ionized water (DI) water, house vacuum, and compressed air. It is expressly understood that no gases (other than compressed air) will be supplied to the Subleased Premises by FibroGen. However, FibroGen will (at no cost to Subtenant) install wall mounts to secure laboratory gas cylinders in the Subleased Premises subject to the restrictions contained in Paragraph 9.5. FibroGen represents that

the DI water, house vacuum and compressed air are, and shall be, maintained by FibroGen in good working order.

No such services shall be available during nights, weekends, and FibroGen holidays.

5.2 Services and utilities not specified in Paragraph 5.1 above, shall be furnished and the cost borne as outlined in Exhibit A. If any such services are not separately metered to Subtenant, Subtenant shall pay a reasonable proportion to be determined by FibroGen of all charges jointly metered with other premises. In the event of failure by FibroGen to furnish, in a satisfactory manner, any of the services and utilities to the Premises for which FibroGen is responsible, Subtenant may furnish the same if FibroGen has not undertaken to correct such failure within five (5) days after written notice, and, in addition to any other remedy Subtenant may have, may deduct the amount thereof, including Subtenant’s service costs, from rent or other remuneration due FibroGen hereunder.

5.3 Charges for all services provided hereunder shall be invoiced on the fifteenth (15th) day of each month immediately following the provision of the service and shall be due and payable along with the next rent payment due after receipt of the invoice for such services.

5.4 Exhibit A may be amended in a signed writing to include new service or remove existing services as mutually acceptable to the parties hereto.

6. TAXES

6.1 FibroGen specifically calls to Subtenant’s attention the fact that this Sublease may create a possessory interest subject to property taxation, and Subtenant may be subject to property tax levied on such interest. Subtenant alone shall pay such tax. If the right is given to pay any of the taxes, assessments or other impositions which Subtenant is herein obligated to pay either in one sum or in installments, Subtenant may elect either mode of payment.

6.2 Subtenant shall pay prior to delinquency all taxes assessed against and levied upon trade fixtures, furnishings, equipment and all other personal property of Subtenant contained in the Premises or elsewhere. Subtenant shall cause said trade fixtures, furnishings, equipment and all other personal property to be assessed and billed separately from the real property of FibroGen.

7. SECURITY DEPOSIT

7.1 On or before the date of final signature by both parties hereto, Subtenant shall deposit with FibroGen a sum equal to one hundred percent (100%) of the first month’s Rent; and on or before the Sublease Commencement Date, Subtenant shall deposit with FibroGen an additional sum equal to two hundred percent (200%) of the first month’s Rent both sums as security for the full and faithful performance of each provision of this Sublease.

7.2 Subtenant shall provide a properly completed, signed and dated IRS Form W-9 or Form W-8BEN (as applicable, the “IRS W8/9 Form”) to FibroGen.

7.3 If Subtenant defaults with respect to any provision of this Sublease, including, but not limited to, the provisions relating to the payment of Rent or other charges, FibroGen may use, apply or retain all or any part of said deposit for the payment of Rent or other charges in default; or for the payment of any other amount which FibroGen may spend or become obligated to spend by reason of Subtenant’s default. If any portion of said deposit is so used or applied, Subtenant shall, within ten (10) days after written demand therefore, deposit cash with FibroGen in an amount sufficient to restore said deposit to the full amount hereinabove stated, and Subtenant’s failure to do so shall be a material breach of this Sublease. If Subtenant fully and faithfully performs every provision required by this Sublease, said deposit, or so much thereof as has not theretofore been applied or credited by FibroGen shall be returned to Subtenant (or, at FibroGen’s option, to the last assignee of Subtenant’s interest hereunder) at the expiration of the term hereof. The making by Subtenant of such deposit, or the application thereof by FibroGen in the manner hereinabove provided, shall not constitute nor be construed as a limitation upon the exercise by FibroGen of any other rights or remedies provided to FibroGen under the terms of this Sublease in the event of Subtenant’s default. In the event FibroGen sells or assigns FibroGen’s interest in the 409 Building, FibroGen may assign said deposit to the purchaser of FibroGen’s interest in the demised premises without liability to Subtenant. FibroGen’s obligations with respect to the deposit are those of a debtor and not a trustee. FibroGen may maintain the deposit separate and apart from FibroGen’s general funds or can commingle the deposit with FibroGen’s general and other funds.

10.2 Each party hereto shall treat the Confidential Information of the other as proprietary and confidential and hold it in strict trust and confidence using at least the same degree of care as it uses to protect its own most highly confidential information, but in no event, using less than a reasonable degree of care.

b) reverse engineer or reverse compile the Confidential Information;

c) make any commercial use of the Confidential Information;

d) use any Confidential Information to support any patent application or related filing; or

10.3 Each party hereto shall advise its officers, employees, independent contractors and business invitees who might have access to Confidential Information of the confidential nature thereof.

10.4 The knowledge of Confidential Information by one party shall not constitute any grant, option, or license to the other in any intellectual property rights or interest in the Confidential Information now or hereinafter.

10.5 The parties hereto agree that for any violation of any provision of this Section 10 (Confidentiality), the aggrieved party shall be entitled, in addition to any other remedies it may have and without the need to post a bond, to specific performance, injunctions or other appropriate remedies it may have for any such violation by the non-aggrieved party.

FibroGen shall have ten (10) business days to object to any defects or damage present on the Damage List. After the ten day period after Sublease Commencement Date, Subtenant shall be precluded from claiming any defect or damage was present in the Subleased Premises or on the furniture or cubicles if such defect or damage was not present on the Damage List prior to the Sublease Commencement Date.

11.5 Upon the expiration or termination date of this Sublease pursuant to Article 3.2, Subtenant shall surrender to FibroGen the Subleased Premises and any and all cubicles, furniture, equipment and fixtures supplied by FibroGen in the same condition and repair as received (ordinary wear and tear, damage, and casualty that Subtenant under the Master Lease has no obligation to restore or repair excepted), broom-clean, and otherwise in the condition required by the Master Lease and shall repair any damage to the Subleased Premises occasioned by the removal of Subtenant’s fixtures, furnishings, and equipment.
