LEASE OF PREMISES 

Section 2.1 Lease Of The Premises. Landlord hereby leases the Premises to Tenant, and Tenant hereby leases the Premises from
Landlord, upon and subject to the terms and provisions of this Lease and all zoning ordinances and all matters of record affecting the Project. 

Section 2.2 Common Rights; Cafeteria; Common Facilities. The Premises are leased subject to, and with the benefit of, the non-exclusive right to use in common with others at any time entitled thereto the Common Areas and Common Facilities for all such purposes as such areas may be designated, but only in connection with lawful business
in the Building and in accordance with the Rules and Regulations. Landlord shall have the right from time to time to designate or change the number, locations, size or configuration of the Common Areas, and to modify or replace the Common
Facilities, and to permit expansion and new construction therein. Tenant shall not have the right to use those portions of the Common Areas designated from time to time by Landlord as for the exclusive use of one or more other tenants. Landlord
shall cause a cafeteria and a fitness center to be located in the common area of the Building. In the event that in Landlord’s reasonable opinion, it becomes uneconomical for Landlord to operate the Cafeteria during the Lease Term, then upon
thirty (30) days’ written notice to Tenant, Landlord shall no longer be obligated to provide a Cafeteria in the Building. In addition, at any time that Tenant does not maintain restrooms within its Premises, Landlord shall maintain common
restrooms in reasonable proximity to the Premises. 
 Section 2.3 Parking. Subject to the Rules and Regulations, Tenant’s
Invitees are authorized to use Tenant’s Share of the parking spaces in the Parking Areas, in common with Landlord and other tenants of the Project from time to time. In the event of (a) a decrease in the number of parking spaces on the

reserved for Tenant), (c) permit the total number of passenger automobiles parked on the Project by Tenant’s Invitees, at any time, to exceed Tenant’s Share of the parking spaces in the Parking Areas, and (d) except for delivery
trucks using designated loading and unloading facilities, permit any of Tenant’s Invitees to park any vehicle on the Project other than passenger automobiles. Landlord may, from time to time, designate one or more spaces as reserved for the
exclusive use of one or more of the tenants of the Project and/or for Landlord’s Invitees.

 Section 2.4 Lease Term. 

(a)    The Lease Term shall commence at 12:01 a.m. on the Commencement Date and shall end at 11:59 p.m. on the last day of
the seventh (7th) Lease Year. At the request of Landlord or Tenant made on or after the Commencement Date, Landlord and Tenant will execute a written amendment to, and restatement of, the Summary of Basic Terms pursuant to Section 2.7, setting
forth the Commencement Date. 
 (b)    Provided an Event of Default does not then exist, Tenant shall have the right to
extend the Lease Term one period of 5 years by giving Landlord written notice of extension, which notice must be received by Landlord not earlier than 18 months, nor later than 12 months, prior to expiration of the Initial Term. If such extension
becomes effective, the Lease Term shall be automatically extended upon the same terms and conditions as were applicable to the Initial Term, except that (i) Base Rent for the Extension Term shall be as set forth in Section 4.1(b), and
(ii) there shall be no further right to extend or renew the Lease Term beyond the Extension Term. The right of extension provided under this Section 2.4(b) is personal to Advantagene, Inc., d/b/a Candel Therapeutics (or its Permitted
Transferee) and is not exercisable by any subtenant or other assignee permitted hereunder. 
 Section 2.5 Security Deposit. 

(a)    Simultaneously with the execution and delivery of this Lease, Tenant shall deliver to Landlord the Security Deposit,
which shall be in the form of cash or a letter of credit which satisfies the conditions of Section 2.5(b) (“Letter of Credit”). 

(b)    The Letter of Credit must satisfy all of the following conditions: (i) the Letter of Credit must be in the
form attached hereto as Exhibit E. or in such other substantially similar form as Landlord may approve, with an expiration date not less than one year after the date of the Letter of Credit; (ii) the beneficiary of the Letter of Credit
must be Landlord or Landlord’s designee; (iii) the Letter of Credit must be irrevocable, unconditional and transferable one or more times without charge to Landlord; (iv) the Letter of Credit must be issued by a bank satisfactory to
Landlord in its reasonable discretion; and (v) the Letter of Credit must provide that it may be drawn at a location in Boston, Massachusetts. If, at any time, the issuer of the Letter of Credit gives notice of its election not to renew, extend
and/or reissue the Letter of Credit, then Tenant shall, not later than 30 days prior to the expiration of the term of the Letter of Credit, deliver to Landlord (1) a replacement Letter of Credit satisfying all of the above conditions or
(2) cash in the full amount of the expiring Letter of Credit; and if Tenant fails to timely deliver to Landlord a replacement Letter of Credit as provided above or cash in the full amount of the expiring Letter of Credit, such failure shall
constitute an Event of Default and, in addition to any other rights which Landlord might have by reason of such Event of Default, Landlord may draw on the Letter of Credit and hold the proceeds of such drawing as the Security Deposit. If
(x) Landlord shall reasonably feel insecure with the creditworthiness of the bank issuing the Letter of Credit and Tenant shall fail, within ten days after notice, to either provide a replacement Letter of Credit as provided above or cash in
the full amount of the existing Letter of Credit, or (y) Tenant fails to provide Landlord with cash in the full amount of the Letter of Credit within ten days after (I) any proceedings under the Bankruptcy Code, receivership or any
insolvency law are instituted with the issuer of the Letter of Credit as debtor or (II) the bank issuing the Letter of Credit is taken over by the Federal Deposit insurance Corporation, the Resolution Trust Corporation or a similar entity, then
such failure by Tenant under clauses (x) or (y) of this sentence shall constitute an Event of Default and, in addition to any other rights which Landlord might have by reason of such Event of Default, Landlord may draw on the Letter of Credit
and hold the proceeds of such drawing as part of the Security Deposit. 
 (c)    The Security Deposit is security for
the faithful performance and observance by Tenant of Tenant’s obligations under this Lease and is not an advance payment of rent. If an Event of Default occurs, Landlord may use, apply or retain the whole or any part of the Security Deposit to
the extent required for payment of any Base Rent or Additional Rent which is then due and payable or for any sum 

  
 6 

 
which Landlord may expend or may be required to expend by reason of the occurrence of an Event of Default, including, but not limited to, any damage or deficiency accrued before or after summary
proceedings or other re-entry by Landlord, including the costs of such proceeding or re-entry and further including, without limitation, reasonable attorneys’ fees.
Landlord shall always have the right to apply the Security Deposit, or any part thereof, as aforesaid, without notice and without prejudice to any other remedy which Landlord may have, or Landlord may pursue any other such remedy in lieu of applying
the Security Deposit or any part thereof. No interest shall be payable on the Security Deposit and Landlord shall have the right to commingle the Security Deposit with other funds of Landlord. If Landlord shall apply the Security Deposit in whole or
in part, Tenant shall immediately upon demand pay to Landlord the amount so applied, or cause the Letter of Credit to be reinstated, to restore the Security Deposit to its original amount. Because elements of Additional Rent may be subject to annual
reconciliation based on actual amounts determined to be due, in addition to the other rights provided herein to Landlord regarding the Security Deposit, Landlord shall have the right, in its discretion, upon the end of the Lease and delivery of the
Premises in accordance with the terms hereof, to hold a portion of the Security Deposit until such reconciliation, at which time Landlord has the right to deduct any amounts then determined to be due from the remaining Security Deposit and return
any balance of the Security Deposit to Tenant; provided that Landlord may not withhold from the Security Deposit an amount greater than the amount which Landlord reasonably estimates will be owing by Tenant upon completion of such reconciliation. If
the remaining Security Deposit is not sufficient to pay Tenant’s obligations hereunder, Tenant shall pay the same within ten days of billing from Landlord. In the event of a sale or other transfer of the Project, or leasing of the entire
Project including the Premises subject to Tenant’s tenancy hereunder, Landlord shall transfer the Security Deposit then remaining to the vendee or lessee, Landlord shall thereupon be released from all liability for the return of such Security
Deposit to Tenant, and Tenant shall look solely to the new landlord for the return of the Security Deposit then remaining. Tenant will not assign or encumber or attempt to assign or encumber the Security Deposit, and neither Landlord nor its
successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. 

Section 2.6 Right of First Offer. 

(a)    Grant of Right. Tenant shall have, and Landlord hereby grants to Tenant, a onetime right of first opportunity
to lease in its entirety the 17,798 square foot portion of the Building adjacent to the Premises and shown on Exhibit D attached hereto (the “ROFO Space”) when it is or becomes available (but no earlier than
September 30, 2020) for lease after the date of this Lease during the Lease Term, on and subject to the terms and conditions set forth in this Section 2.6. Landlord will not extend any existing lease for the ROFO Space, or enter into any
lease of any of the ROFO Space with a tenant other than Tenant (a “Third-Party Lease”) unless and until Landlord has given to Tenant a Notice of Availability (as defined below) with respect to such ROFO Space and Tenant has failed
to exercise its right to lease such ROFO Space pursuant to subsection (b) below. 
 (b)    Notices of
Availability. At any time during the Lease Term that any ROFO Space is, becomes or is about to become available for lease, Landlord may give written notice to Tenant of such availability (a “Notice of Availability”). Any such
Notice of Availability shall specify the date on or about which such ROFO Space is expected to become available for lease (if it is not then available), the lease term which Landlord desires to offer (“ROFO Space Term”), the
permitted use of the ROFO Space and Landlord’s determination of the ROFO Market Rent (as defined below) and such other terms which Landlord desires to specify that relate to the specific ROFO Space. Tenant shall not disclose to third parties,
other than Tenant’s employees, consultants and other agents who have a need to know, the contents of any Notice of Availability, and Tenant shall cause all such employees, consultants or agents to respect the confidentiality of the contents
thereof. Within ten (10) Business Days following Tenant’s receipt of a Notice of Availability, Tenant shall notify Landlord in writing whether Tenant (i) accepts the terms offered in the Notice of Availability, in which case, Tenant
shall be bound to lease the ROFO Space on the terms set forth in the Notice of Availability, and otherwise, subject to the provisions of this Lease, (ii) accepts the offer to lease the ROFO Space, but disputes Landlord’s determination of
the ROFO Market Rent (a “Disputed Acceptance”), in which case, Tenant shall be bound to lease the ROFO Space at the ROFO Market Rent determined pursuant to Section 2.6(c), the other terms set forth in the Notice of
Availability, and otherwise, subject to the provisions of the Lease, or (iii) declines to accept the terms offered in the Notice of Availability 

  
 7 

 
or to accept the offer to lease the ROFO Space and dispute Landlord’s determination of the ROFO Market Rent; provided, further, that if Tenant does not respond in writing to Landlord within
such ten (10) Business Day period, Tenant will be deemed to have made such declination described in the preceding clause (iii). 
 In addition,
Tenant’s right to lease ROFO Space under this Section 2,6 shall apply only to the entire ROFO Space specified in a Notice of Availability, and Tenant shall not have the right under this Section 2,6 to lease less than all of such ROFO
Space. For purposes of this Section 2.6, the term “ROFO Market Rent” means the then fair market rent on a triple-net basis per square foot for the ROFO Space taking into account the use thereof
and may include escalations at various points during the ROFO Space Term. 
 (c)    (i)     In the
event that Tenant timely sends a Disputed Acceptance to Landlord, then for a period of 15 days after Landlord receives the Disputed Acceptance (such period being called the “ROFO Negotiation Period”), Landlord and Tenant shall
negotiate in good faith to attempt to agree upon the ROFO Market Rent, and, in the course of such negotiations, each party may from time to time submit modified proposals to the other. If the parties agree upon the ROFO Market Rent prior to the
determination of the arbitrator pursuant to Section 2.6(c)(ii), whether such agreement is reached during or after the ROFO Negotiation Period, the ROFO Market Rent shall be as so agreed. 

(ii)    If the parties are unable to agree upon the ROFO Market Rent within the ROFO Negotiation Period, then each party
shall, upon selection of an arbitrator pursuant to Section 2.6(c)(iii), simultaneously submit to the arbitrator for binding arbitration a proposal as to the ROFO Market Rent. The ROFO Market Rent shall be determined as of the commencement of
the ROFO Space Term at the then current arms-length negotiated base rents being charged for comparable space and permitted use to the ROFO Space as specified in the Notice of Availability in comparable buildings located in the market area of the
Project, taking into consideration all relevant factors set forth in the Notice of Availability; provided, that the arbitrator shall not have the right to modify any provision of the Lease except Base Rent. Within 30 days after both parties have
submitted such proposals to the arbitrator, the arbitrator shall select one of the proposals as more closely approximating the ROFO Market Rent appropriate for the ROFO Space Term, and, unless the parties have then agreed upon the ROFO Market Rent,
the proposed ROFO Market Rent set forth in such proposal selected by the arbitrator shall be deemed to be the ROFO Market Rent. 

(iii)    If the parties are unable to agree upon the ROFO Market Rent within the ROFO Negotiation Period, then the
parties shall, within 15 days after the end of the ROFO Negotiation Period (such 15 day period being herein called the “ROFO Selection Period”), attempt to agree upon an arbitrator to whom to submit the determination of ROFO Market
Rent for binding arbitration pursuant to Section 2.6(c)(ii). If the parties are unable to agree upon an arbitrator within the ROFO Selection Period, then, at the end of the ROFO Selection Period, each party shall select an arbitrator and,
within 15 days after the end of the ROFO Selection Period, the arbitrators shall agree upon an arbitrator to whom the determination of ROFO Market Rent shall be submitted for binding arbitration pursuant to Section 2.6(c)(ii). If such
arbitrators are unable to agree promptly upon an arbitrator, an arbitrator shall be selected by the American Arbitration Association. Any arbitrator selected by either party, by the arbitrators selected by the parties or by the American Arbitration
Association shall be independent of both parties and shall have such experience, either as a licensed real estate broker or as an appraiser for at least ten years, as would qualify such arbitrator as an expert with respect to leasing terms in the
market area of the Project. Such arbitrator shall make the determination required pursuant to Section 2.6(c)(ii) within 30 days after selection. The parties shall share equally the fees and expenses of the arbitrator to whom the determination
of ROFO Market Rent is submitted. Landlord and Tenant shall each pay the fee of the arbitrator selected by it. 

(d)    Addition of Space to Lease. If Tenant exercises its right to lease any ROFO Space pursuant to subsection
(b) above, then, as of the date specified in the Notice of Availability, such ROFO Space shall be added to and become a part of the Premises and subject to the terms and conditions of this Lease; provided that (x) Landlord shall not be
responsible for making any improvements or alterations to such ROFO Space or providing any improvement allowance with respect thereto, except to the extent provided for in the Notice of Availability; (y) the effective rent (including Base Rent
and Additional Rent, if applicable) for the ROFO Space shall be the effective rent set forth in the Notice of Availability or, if Tenant 

  
 8 

 
timely submits a Disputed Acceptance, as determined by the process set forth in subsection (c) above, and (z) the terms and conditions of this Lease with respect to such ROFO Space
shall be modified by any terms agreed by the parties. Promptly after Tenant exercises its right to lease any ROFO Space pursuant to subsection (b) above or, if Tenant timely submits a Disputed Acceptance, after the ROFO Market Rent is
determined pursuant to subsection (c) above, Landlord and Tenant shall enter into an amendment of this Lease incorporating such ROFO Space as part of the Premises, subject to the terms and conditions of this Lease and incorporating any
additional terms agreed by the parties. 
 (e)    Lapse of Right. If Landlord gives a Notice of Availability and
does not receive Tenant’s notice of exercise pursuant to subsection (b) above within the period specified therein or if Tenant leases the ROFO Space as provided herein, Tenant’s right of first opportunity provided for in this
Section 2.6 shall lapse with respect to all other space and Landlord shall be free to lease such space to third parties without complying with this Section 2.6. 

(f)    Termination of Right Tenant’s right of first opportunity provided for in this Section 2.6 shall
terminate twelve (12) months before the expiration of the Initial Term, unless Tenant timely exercises its extension option pursuant to Section 2.4(b), and, if Tenant timely exercises such extension option, twelve (12) months before
the expiration of the Extension Term. 
 (g)    Rights Personal to Party Executing this Lease. The rights in this
Section 2.6 are personal to Advantagene, Inc., d/b/a Candel Therapeutics, and are not assignable or transferable other than to a Permitted Transferee. Tenant’s rights under this Section 2.6 will lapse and be of no further force and
effect upon any assignment of this Lease other than to a Permitted Transferee. 
 (h)    Event of Default. If an
Event of Default shall have occurred and be continuing, Landlord shall have no obligation to give any Notice of Availability to Tenant, and Tenant shall have no rights under this Section 2.6 if an Event of Default exists on the date on which
Tenant attempts to exercise its right to lease any ROFO Space. 
 Section 2.7 Lease Amendment. If, pursuant to any provision of
this Lease, there results a change in (or, in the case of the Commencement Date, the confirmation of) any of the terms or amounts in the Summary of Basic Terms (including, without limitation, the Leasable Square Footage of the Building, the Leasable
Square Footage of the Premises, Base Rent, or Tenant’s Share) then in effect, Landlord and Tenant will promptly execute a written amendment to, and restatement of, the Summary of Basic Terms, substituting the changed (or confirmed) terms and
recomputed amounts in lieu of each of the applicable terms and amounts then in effect which have been changed. As of the effective date of the amendment to the Summary of Basic Terms, the changed terms (and recomputed amounts) will be effective for
all purposes of this Lease, and the amended and restated Summary of Basic Terms will be a part of, and incorporated into, this Lease. 

ARTICLE III

Installations”); provided, however, that (i) such construction shall be deemed to be part of Tenant’s Work and subject to the provisions hereof applicable thereto, including without limitation, the provisions providing for
Landlord’s approval of the plans and specifications applicable thereto and the requirement that such work be performed in a good and workmanlike manner using new and/or high quality materials and in accordance with Legal Requirements,
(ii) the Double-Wide Door Installations shall not violate any existing permits applicable to the Property and shall not require any modification thereto unless approved by Landlord in writing, in which case, Tenant shall be solely responsible

(b)    Any entry by Tenant into the Premises prior to the Commencement Date shall be at Tenant’s own risk solely for
the purpose of designing and performing Tenant’s Work, installing fixtures and equipment, and otherwise preparing the Premises for occupancy by Tenant. During the period of any entry by Tenant prior to the Commencement Date pursuant to the

insurance confirming its procurement of the insurance required by Sections 7.8 and 7.9. Notwithstanding the foregoing, subject to Tenant complying with applicable Legal Requirements and obtaining all governmental approvals necessary to do so, upon

Commencement Date, Tenant shall pay to Landlord a monthly rental rate equal to $12,000, which shall be prorated for any partial month. 

Section 3.3 Allowance. Landlord will provide an amount up to the Allowance to or for the benefit of Tenant to pay or reimburse
Tenant for costs of alterations and improvements to the Premises, including permits, architectural and engineering (but excluding costs for Tenant’s equipment, furniture, trade fixtures, the Double-Wide Door Installations and personal
property), performed by Tenant from and after the date of this Lease. Disbursement of the Allowance to or at the direction of Tenant shall be conditioned on the subject alterations and improvements having been performed in accordance with the
provisions of this Lease, and shall be subject to Landlord’s receipt of a request for payment in form and with backup reasonably satisfactory to Landlord, including but not limited to such certifications, lien waivers and other documents from
Tenant, Tenant’s contractor and Tenant’s architect as Landlord may reasonably require. Landlord may inspect the subject alterations and improvements as a condition to making any requested disbursement of the Allowance to confirm the status
of such alterations and improvements and that such alterations and improvements have been performed in accordance with the provisions of this Lease. In the 

  
 10 

 
event that the cost of Tenant’s Work or any such alterations and improvements to the Premises exceeds the amount of the Allowance, Tenant shall be entirely responsible for such excess. Any
portion of the Allowance for which Tenant has not qualified for disbursement within fourteen months after the Commencement Date shall be forfeited by Tenant. 

Section 3.4 Signs. Tenant shall not have the right to install or erect any sign on the exterior or outside of the Building. Tenant

ARTICLE IV 

BASE RENT; ADDITIONAL RENT 

Section 4.1 Base Rent. 

(a)    Tenant shall pay Base Rent in the amounts set forth in Item 9 of the Summary of Basic Terms. 

(b)    (i)     The Base Rent per square foot for the Extension Term will be at a rate equal to 95% of
the then fair market rent on a triple-net basis per square foot for the Premises and may include escalations at various points during the Extension Term (the “Market Rent”), determined in
accordance with this Section 4.1(b). For a period of 30 days after Tenant gives to Landlord written notice of exercise of the extension option pursuant to Section 2.4(b) (such period being called the “Negotiation Period”).
Landlord and Tenant shall negotiate in good faith to attempt to agree upon the Market Rent, and, in the course of such negotiations, each party may from time to time submit modified proposals to the other. If the parties agree upon the Market Rent
prior to the determination of the arbitrator pursuant to Section 4.1 (b)(ii), whether such agreement is reached during or after the Negotiation Period, the Market Rent shall be as so agreed. 

(ii)    If the parties are unable to agree upon the Market Rent within the Negotiation Period, then each party shall,
upon selection of an arbitrator pursuant to Section 4.1 (b)(iii), simultaneously submit to the arbitrator for binding arbitration a proposal as to the Market Rent. The Market Rent shall be determined as of the commencement of the Extension Term
at the then current arms-length negotiated base rents being charged for comparable space in comparable buildings located in the market area of the Project, taking into consideration all relevant factors. The arbitrator shall not have the right to
modify any provision of the Lease except Base Rent. Within 30 days after both parties have submitted such proposals to the arbitrator, the arbitrator shall select one of the proposals as more closely approximating the Market Rent appropriate for the
Extension Term, and, unless the parties have then agreed upon the Market Rent, the proposed Market Rent set forth in such proposal selected by the arbitrator shall be deemed to be the Market Rent. 

(iii)    If the parties are unable to agree upon the Market Rent within the Negotiation Period, then the parties shall,
within 15 days after the end of the Negotiation Period (such 15 day period being herein called the “Selection Period”), attempt to agree upon an arbitrator to whom to submit the determination of Market Rent for binding arbitration
pursuant to Section 4.1 (b)(ii). If the parties are unable to agree upon an arbitrator within the Selection Period, then, at the end of the Selection Period, each party shall select an arbitrator and, within 15 days after the end of the
Selection Period, the arbitrators shall agree upon an arbitrator to whom the determination of Market Rent shall be submitted for binding arbitration pursuant to Section 4.1 (b)(ii). If such arbitrators are unable to agree promptly upon an
arbitrator, an arbitrator shall be selected by the American Arbitration Association. Any arbitrator selected by either party, by the arbitrators selected by the parties or by the American Arbitration Association shall be independent of both parties
and shall have such experience, either as a licensed real estate broker or as 

  
 11 

 
an appraiser for at least ten years, as would qualify such arbitrator as an expert with respect to leasing terms in the market area of the Project. Such arbitrator shall make the determination
required pursuant to Section 4.1 (b)(ii) within 30 days after selection. The parties shall share equally the fees and expenses of the arbitrator to whom the determination of Market Rent is submitted. Landlord and Tenant shall each pay the fee
of the arbitrator selected by it. 
 (c)    Base Rent shall be payable in equal monthly installments of one-twelfth of the annual Base Rent then in effect and shall be paid without offset for any reason, in advance, on the first day of each calendar month during the Lease Term. If the Commencement Date is not on the
first day of a calendar month, Tenant shall pay, on or before the Commencement Date, a proportionate part of the Base Rent for the month in which the Commencement Date occurs based upon the annual Base Rent then in effect, divided by 360 and then
multiplied by the number of days from and including the Commencement Date through and including the last day of such month. Base Rent and Additional Rent shall be paid by an “electronic funds transfer” system arranged by and among Tenant,
Tenant’s bank and Landlord by Tenant submitting to Landlord a completed electronic transfer form as set forth in Exhibit H. The parties acknowledge and agree that the obligations owing by Tenant under this Section are rent reserved under
this Lease, for all purposes hereunder, and are rent reserved within the meaning of Section 502(b)(6) of the Bankruptcy Code or any successor provision thereto. 

Section 4.2 Certain Additional Rent. Tenant shall pay, without offset for any reason, all payments of Additional Rent payable by
Tenant to Landlord hereunder as and when required by Sections 4.3 through 4.6 and as otherwise set forth in this Lease. If Tenant fails to pay any Additional Rent, Landlord shall have all the rights and remedies for failure to pay Base Rent. The
obligations owing by Tenant under this Section are rent reserved under this Lease, for all purposes hereunder, and are rent reserved within the meaning of Section 502(b)(6) of the Bankruptcy Code or any successor provision thereto. 

Section 4.3 Taxes. 

(a)    Tenant shall pay to Landlord, as Additional Rent, an amount equal to Tenant’s Share of Taxes. Such amounts
shall be estimated in good faith by Landlord at the end of each Tax Fiscal Year (based on the most recent tax data available to Landlord), and shall be payable to Landlord in equal estimated monthly installments on the first day of each calendar
month during the Lease Term, subject to readjustment when the actual amount of Taxes is determined. After readjustment, any shortage shall be due and payable by Tenant within 30 days of demand by Landlord and any excess shall, unless an Event of
Default has occurred, be credited against future Additional Rent obligations, or refunded if the Lease Term has ended and Tenant has no further obligations to Landlord. If the taxing authority provides an estimated tax bill, then monthly
installments of Taxes shall be based thereon until the final tax bill is ascertained. 
 (b)    If, after Tenant shall
have made any payment under this Section, Landlord shall receive a refund (the “Refund”) of any portion of the Taxes paid on account of any Tax Fiscal Year in which such payments shall have been made as a result of an abatement of
such Taxes, by final determination of legal proceedings, settlement or otherwise, Landlord shall, within 30 days after receiving the Refund, pay to Tenant (unless an Event of Default then exists) an amount equal to (i) Tenant’s Share of
the Refund, which payment to Tenant shall be appropriately adjusted if Tenant’s Tax Share covered a shorter period than covered by the Refund; provided, however, that payments withheld from Tenant under this section because of an existing Event
of Default, shall be remitted to Tenant promptly after such Event of Default is cured by Tenant and accepted by Landlord; (ii) less Tenant’s Share of all expenses incurred by Landlord in connection with such proceedings (including, but not
limited to, attorneys’ fees, costs and appraisers’ fees) to the extent such expenses have not been previously paid by Tenant as Taxes hereunder. Landlord shall have sole control of all such proceedings. 

(c)    If the Commencement Date of this Lease is not on July 1, or the expiration or termination of this Lease is not
on June 30, Tenant’s obligation in respect of Taxes shall be prorated. If the final tax bill for the Tax Fiscal Year in which such expiration or termination of this Lease occurs shall not have been received by Landlord, then within 30 days
after the receipt of the tax bill for such Tax Fiscal Year, Landlord and Tenant shall make appropriate adjustments of estimated payments. 

  
 12 

 (d)    Without limiting the generality of the foregoing, Tenant shall
pay all rent and personal property taxes attributable to its signs or any other personal property including but not limited to its trade fixtures, the existing or any future floor coverings, wall treatments and light fixtures in the Premises. 

Section 4.4 Insurance Costs. Tenant shall pay to Landlord, as Additional Rent, an amount equal to Tenant’s Share of Insurance
Costs. Tenant’s Share of Insurance Costs shall be estimated in good faith by Landlord at the end of each calendar year based on the most recent cost data available to Landlord, and shall be payable in equal estimated monthly installments on the
first day of each calendar month during the Lease Term, subject to readjustment from time to time as determined by Landlord and also when actual Insurance Costs are determined. After a readjustment, any shortage shall be due and payable by Tenant
within 30 days of demand by Landlord and any excess shall, unless an Event of Default then exists, be credited against future Additional Rent obligations, or refunded promptly if the Lease Term has ended and Tenant has no further obligations to
Landlord, provided, however, that payments withheld from Tenant under this section because of an existing Event of Default, shall be remitted to Tenant promptly after such Event of Default is cured by Tenant. Landlord shall provide Tenant with
reasonable supporting documentation for the Insurance Costs for the prior calendar year within six months after the end of the calendar year to which such Insurance Costs relate. 

Section 4.5 Operating Costs. Tenant shall pay to Landlord, as Additional Rent, amounts equal to Tenant’s Share of Operating
Costs. For purposes of determining Tenant’s Share of Operating Costs, for any calendar year during which the Building is less than 95% occupied, the Operating Costs shall be equitably adjusted, on an item-by-item basis, for such calendar year to reflect the amount which, in Landlord’s good faith reasonable judgment exercised on a consistent basis from year to year, the Operating Costs would have been
if the Building had been 95% occupied during the entire calendar year. Tenant’s Share of Operating Costs shall be estimated in good faith by Landlord at the end of each calendar year based on the most recent cost data available to Landlord, and
shall be payable in equal estimated monthly installments on the first day of each calendar month during the Lease Term, subject to readjustment from time to time as determined by Landlord and also when actual Operating Costs are determined. After a
readjustment, any shortage shall be due and payable by Tenant within 30 days of demand by Landlord and any excess shall, unless an Event of Default has occurred, be credited against future Additional Rent obligations, or refunded promptly if the
Lease Term has ended and Tenant has no further obligations to Landlord. Landlord shall provide Tenant with reasonable supporting documentation for the Operating Costs for the prior calendar year within six months after the end of the calendar year
to which such Operating Costs relate. 
 Section 4.6 Payment for Electricity. The Premises shall be separately metered or
check-metered by Landlord (at Landlord’s expense) for electrical use for lights and plugs (exclusive of electricity for heating, ventilating and air conditioning to the extent subject to the provisions of the following paragraph). Tenant shall
promptly pay all charges related to its use of electricity for lights and plugs (exclusive of electricity for heating, ventilating and air conditioning to the extent subject to the provisions of the following paragraph), (i) to the appropriate
public utility if the Premises are separately metered, or (ii) to Landlord within thirty (30) days of being invoiced therefor if the Premises are check-metered To the extent that the heating, ventilating and air conditioning system serving
the Premises is operated and powered by electricity that is measured by a separate meter that also measures the electrical consumption used to operate and power the heating, ventilating and air conditioning system serving other tenants’
premises in the Building, then within thirty (30) days of receipt of an invoice from Landlord therefor, Tenant shall pay its share of the cost of electricity measured by such meter on the basis of the ratio of the floor area of the Premises to
the total floor area served by the heating, ventilating and air conditioning system operated and powered by such separate meter. 

Section 4.7 Tenant’s Audit Rights . Annually, Landlord shall furnish to Tenant a report setting forth in reasonable detail
the Operating Costs, Insurance Costs and Taxes for the immediately preceding calendar year (in the case of Operating Costs and Insurance Costs) or Tax Fiscal Year (in the case of 

  
 13 

 
Taxes). Tenant shall have the right to audit Landlord’s books and records relating to Operating Costs, Insurance Costs and/or Taxes with respect to the period covered by each such report
provided and on the condition that Tenant delivers a written notice of its intention to perform such audit to Landlord not later than ninety (90) days after receipt of such report (such ninety day period being called the “Audit
Period”), time being of the essence. If, as a result of such audit, Tenant believes that it is entitled to receive a refund of any Additional Rent paid by Tenant in respect of Operating Costs, Insurance Costs and/or Taxes, Tenant shall
deliver to Landlord, no later than 30 days after expiration of the Audit Period, a notice demanding such a refund, together with a statement of the grounds for each such demand and the amount of each proposed refund. The cost of any such audit shall
be paid by Tenant, except that, if it is established that the Additional Rent in respect of Operating Costs, Insurance Costs and Taxes charged to Tenant for the period in question was overstated by more than 5%, the reasonable out-of-pocket cost of such audit paid to a third party other than an employee of Tenant, up to a maximum of $5,000, shall be paid or reimbursed to Tenant by Landlord. An
overstatement shall not be deemed to exist due to a Refund provided timely by Landlord to Tenant. Any audit shall be performed by either (a) Tenant’s regular employees or (b) a reputable certified public accountant reasonably
acceptable to Landlord whose compensation is not directly or indirectly, contingent in whole or in part on the results of the audit. If, after reasonable investigation, Landlord determines that a report previously furnished by Landlord was in error,
Landlord may (but shall if such error resulted in a prior overstatement of Operating Costs, Insurance Costs and/or Taxes) furnish a corrective or supplemental report to Tenant within one year after the original report was furnished, and if such
corrective or supplemental report results in increased Additional Rent, the Audit Period for the year covered by such report shall be extended for six months after Landlord furnishes the corrective or supplemental report. 

ARTICLE V

OF PREMISES 
 Section 5.1 Permitted Use. Tenant shall use and occupy the Premises only for the Permitted Use. Landlord
does not make any representation or warranty to Tenant that Tenant’s use of the Premises for the Permitted Use will comply with Legal Requirements, and Tenant is responsible for confirming such compliance. 

Section 5.2 Restrictions on Use. Tenant shall use the Premises in a careful, safe and proper manner, shall not commit or suffer
any waste on or about the Project, and shall not make any use of the Project which is prohibited by or contrary to any Legal Requirements, or which would cause a public or private nuisance. Tenant, at its own expense, shall obtain any and all
permits, approvals and licenses necessary for use of the Premises. Tenant shall not overload the floors or other structural parts of the Building; and shall not commit or suffer any act or thing on the Project which is illegal, offensive, dangerous,

the Building unless Tenant is willing to pay the increase in such insurance and such act or thing is a Permitted Use and does not otherwise violate any provision of this Lease, including without limitation, those provisions relating to Hazardous
Materials and/or Environmental Laws. If, because of Tenant’s failure to comply with the provisions of this Section or due to any use of the Premises or activity of Tenant in or about the Project, the Insurance Costs are increased, Tenant shall
pay Landlord the amount of such increase caused by the failure of Tenant to comply with the provisions of this Section. Tenant shall cause any fire lanes located within the Project to be kept free of all parking associated with its business or
occupancy. Tenant shall conduct its business at all times so as not to annoy or be offensive to other tenants and occupants in the Building. Tenant shall not permit the emission of any objectionable noise or odor from the Premises and shall at its

the Commencement Date, Tenant shall remove all Hazardous Materials from the Premises in a manner reasonably acceptable to Landlord before the earlier of the date Tenant vacates the Premises and the date Tenant’s right to possess the Premises
ends. Landlord may enter the Premises and conduct environmental inspections and tests therein as it may require from time to time, provided that Landlord shall not unreasonably interfere with Tenant’s business and shall use reasonable efforts
to minimize the interference with Tenant’s business. Such inspections and tests shall be conducted at Landlord’s expense, unless they reveal the presence of Hazardous Materials in violation of the above provisions of this Section or that
Tenant has not complied with the requirements of this Section, in which case Tenant shall reimburse Landlord for the cost thereof within 30 days after Landlord’s request therefor. Tenant shall indemnify, defend upon demand with counsel
reasonably acceptable to Landlord, and hold the Landlord Parties harmless from and against, any liabilities, losses, claims, damages, interest, penalties, fines, attorneys’ fees, experts’ fees, court costs, remediation costs, and other

of the Permitted Hazardous Materials and Quantities and are not any of the types of Hazardous Materials listed on Exhibit K-1 and if any such Hazardous Materials are of the types listed on Exhibit K-2, Tenant shall provide Landlord with at least ten (10) days’ prior written notice prior to using or storing the same in the Premises and shall permit Landlord to review any application for any
Required Permit required for the same at least ten (10) days prior to filing the same and permit Landlord to attend any hearing or meeting with any governmental entity responsible for issuing any Required Permit. In addition, Tenant shall

Lease governing Hazardous Materials. 
 The provisions of this Section 5.3 shall survive the expiration or earlier termination of this Lease.

significant portion thereof, untenantable and such interruption of services continues for ten consecutive Business Days after Tenant gives Landlord written notice thereof, Tenant shall be entitled to an abatement of Base Rent in proportion to the
portion of the Premises rendered untenantable for each day after such tenth Business Day that such untenantable condition continues by reason of such interruption in services and such interruption, without regard to whether it was within the
reasonable control of the Landlord, shall be considered a casualty under Section 10.1.

much of the Premises as were originally constructed by Landlord to substantially their condition immediately prior to the casualty (subject, however, to Legal Requirements then in existence), and Tenant shall concurrently (to the extent practical
and consistent with good construction practices) (i) repair and restore so much of the Premises as were constructed by Tenant or are the responsibility of Tenant under this Lease and (ii) repair and restore its fixtures and personal
property. 
 (b)    If, pursuant to Section 10.1(a), Landlord is required to restore the Premises and Landlord
fails to substantially complete such restoration within 30 days after the end of the Restoration Period (subject to extension for delays described in Section 10.1(c)), then Tenant shall have the right to terminate this Lease upon 30 days prior
written notice to Landlord. If Landlord fails to substantially complete such restoration work within such 30 day period, then this Lease shall terminate as of such 30th day. 

(c)    Landlord shall not be responsible for any delay in commencement of restoration which may result from delays in
adjustment or collection of insurance proceeds beyond the commencement of the Restoration Period; provided, that on account of any such delay, the Restoration Period shall be tolled only up to 60 days and thereafter any such delay shall not extend
the Restoration Period. Notwithstanding any other provisions of this Section 10.1 to the contrary, Landlord shall not be obligated to commence repair or restoration work prior to receipt of sufficient insurance proceeds, nor shall Landlord be
required to expend sums in excess of “net recovered insurance proceeds”. The term “net recovered insurance proceeds” shall mean the amount of any insurance proceeds actually recovered by Landlord, less the cost of
obtaining the same (including attorneys’ fees and appraisal fees) and less the amount thereof required to be paid to a mortgagee or ground lessor. 

Section 10.2 Abatement of Rent. In the event that the provisions of Section 10.1 shall become applicable, the Base Rent and
Additional Rent shall be abated or reduced proportionately during any period in which, by reason of any such damage or destruction, there is substantial interference with the operation of the business of Tenant in the Premises, having regard to the
extent to which Tenant may be required to discontinue its business in the Premises, and such abatement or reduction shall continue (but may be adjusted from time to time based on the extent of the interference with Tenant’s operations) for the
period commencing with such destruction or damage and ending with the substantial completion by Landlord of such work, repair and/or reconstruction as Landlord may do. 

Section 10.3 Landlord’s Right to Terminate. Notwithstanding the foregoing, Landlord may terminate this Lease following:
(a) damage or destruction to the Premises to the extent of 30% or more of the cost of replacement thereof; or (b) the refusal of the applicable insurance carrier to pay funds sufficient for the cost to repair or replace or the refusal of
any applicable mortgagee or ground lessor to release the 

  
 27 

 
insurance proceeds for such purposes. Landlord may exercise the right to so terminate this Lease by written notice to Tenant given within 60 days after the date of the damage or 60 days after the
date Landlord receives written notice of such damage, whichever is later. Such notice of termination shall be effective on the date thereof. 

ARTICLE XI 

EMINENT DOMAIN 

Section 11.1 Eminent Domain; Right to Terminate and Abatement in Rent. If the Premises or any part thereof, or the whole or any
substantial part of the Project, shall be taken, or if a conveyance shall be made in anticipation thereof, for any street or other public use, by action of the municipal, state, federal or other authorities, or shall receive any substantial direct
or consequential damage for which Landlord or Tenant shall be entitled to compensation by reason of anything lawfully done in pursuance of any public authority, after the execution hereof and before the expiration of the Lease Term, then this Lease
and the Lease Term shall terminate at the election of Landlord (given by written notice to Tenant within 30 days of the taking or within 30 days of notice of the taking to Landlord), and such election may be made in case of any such taking
notwithstanding the entire interest of Landlord may have been divested by such taking; and if Landlord does not so elect, then in case of any such taking or destruction of, or damage to, the Premises, rendering the same or any part thereof unfit for
use and occupation, a just proportion of the Base Rent hereinbefore reserved according to the nature and extent of the injury sustained by the Premises as determined by Landlord, shall be suspended or abated until the Premises or, in case of such
taking, what may remain thereof, shall have been put in proper condition for use and occupation. Landlord shall promptly notify Tenant of any taking of any part of the Premises. In addition, if any taking of the Premises permanently renders the
Premises unfit for Tenant’s use and occupation, this Lease and the Lease Term shall terminate at the election of the Tenant (given by written notice to Landlord within 30 days of notice of the taking to Tenant). To the extent that the Premises,
upon having been put in proper condition for use and occupation are smaller, the Base Rent hereinbefore reserved shall be reduced for the balance of the Lease Term in the same proportion which the reduction in space bears to the original Leasable
Square Footage of the Premises. In the event of a taking of any portion of the Building, Tenant’s Share shall be recomputed. 

Section 11.2 Restoration. If this Lease is not terminated as provided in Section 11.1, Landlord shall apply so much of the
available proceeds of the eminent domain award as are required to restore the Project and the Premises to a condition, to the extent practical, substantially the same as that immediately preceding the taking, but subject to zoning laws and building
codes then in existence. If the available proceeds of the eminent domain award are insufficient, in Landlord’s judgment, for that purpose, Landlord shall have no obligation to expend funds in excess of said proceeds and Landlord shall have the
right to select which portions of the Project, if any, shall be restored; however, in such circumstance this Lease and the Lease Term shall terminate at the election of Tenant (given by written notice to Landlord within 30 days of Landlord’s
notice to Tenant of receipt of the award). The term “available proceeds” shall mean the amount of the award paid to Landlord, less cost of obtaining the same (including attorneys’ fees and appraisal fees) and less the amount
thereof required to be paid to a mortgagee or ground lessor. In the event Landlord fails to commence restoration of the Project and/or the Premises within 60 days after the taking, Tenant shall have the right to terminate the Lease upon 60
days’ prior written notice to Landlord. 
 Section 11.3 Landlord to Control Eminent Domain Action. Landlord reserves all
rights to compensation for damage to the Premises or any part thereof, or the leasehold hereby created, heretofore accrued or hereafter to accrue, by reason of any taking for public use of said Premises or any portion thereof, or right appurtenant
thereto, or privilege or easement in, through, under or over the same, and by way of confirmation of the foregoing Tenant hereby assigns all rights to such damages heretofore accrued or hereafter accruing during the Lease Term to Landlord; provided,
however, that notwithstanding anything to the contrary herein Tenant shall have all rights to compensation for damage to laboratory and manufacturing equipment installed on the Premises. However, nothing herein contained shall limit Tenant’s
right to any separate award for the taking of personal property, moving expenses, or other items the payment of which shall not reduce the award payable to Landlord.

 ARTICLE XII 

DEFAULT AND REMEDIES 

Section 12.1 Event of Default. As used herein, “Event of Default” shall mean the occurrence and/or existence of any one
or more of the following: (a)(i) Tenant shall neglect or fail to pay Base Rent, or any installment thereof, or any regularly scheduled installment of Additional Rent on or before the date on which the same becomes due and payable, and such failure
continues for five days after Landlord gives Tenant written notice thereof, or (ii) Landlord having given the notice specified in the foregoing clause (a)(i) to Tenant once in any 12 month period, Tenant shall fail, on another occasion within
12 months after the first such notice, to pay any installment of Base Rent or Additional Rent within five days after due (provided, that such failure is not solely due to an error by Landlord or Landlord’s bank in collecting such installment by
electronic funds transfer when Tenant has adequate available funds in its account to pay such installment); or (b) Tenant shall neglect or fail to perform or observe any of the other covenants or undertakings herein on its part to be performed
or observed and such neglect or failure shall continue for ten days after notice to Tenant; provided that if the default is other than a default under clause (a) above, or clauses (c) through (i) below, and is such that it cannot be cured
within ten days, but is capable of being cured, such ten day period shall be extended by up to 20 additional days provided that Tenant commences to cure such default within said ten day period, continues to do so diligently, and thereafter completes
such cure within not more than 30 days following the notice of default; or (c) there is filed by Tenant any case, petition, proceeding or other action under any Bankruptcy Law; or (d) any other proceedings shall be instituted against
Tenant under any Bankruptcy Law and not be dismissed within 60 days; or (e) Tenant shall execute an assignment of its property for the benefit of its creditors; or (f) a receiver, custodian or other similar officer for Tenant shall be
appointed and not be discharged within 60 days; or (g) the estate hereby created shall be taken by execution or by other process of law and is not redeemed by Tenant within 30 days thereafter; or (h) an assignment or sublease in violation
of the terms of this Lease; or (i) any other event constituting an Event of Default under the express terms of other Sections of this Lease, including, without limitation, Section 2.5. If, as provided above, Landlord is responsible for
collecting rent via electronic funds transfer, then Tenant, other than having inadequate funds, will not be subject to default for any errors or omissions by Landlord or Landlord’s bank. 

Section 12.2 Landlord’s Remedies. 

(a)    Upon the occurrence of an Event of Default and after the lapse of any applicable period of cure, Landlord may,
immediately or at any time thereafter (notwithstanding any license or waiver of any former breach or waiver of the benefit hereof, or consent in a former instance), and without demand or notice, in person or by agent or attorney, enter the Premises
or any part thereof and repossess the same as of its former estate, and/or, by written notice to Tenant, terminate Tenant’s right to possession under this Lease without terminating this Lease or terminate this Lease, and in any such event expel
Tenant and those claiming through or under it and remove their effects (forcibly, if necessary) without being deemed guilty of any manner of trespass and without prejudice to any remedy which might otherwise be used for arrears of Base Rent or
Additional Rent or breach of covenant and Tenant shall remain liable for damages as hereinafter set forth in this Article XII. Whether or not Landlord shall have terminated this Lease or Tenant’s right to possession, Landlord, in addition to
all other remedies which it may have at law or equity, and not in limitation thereof, shall have the remedies provided in this Article XII. 

(b)    If, pursuant to Section 12.2(a), Landlord terminates Tenant’s right of possession of the Premises without
terminating this Lease, then Tenant shall pay to Landlord during the remainder of the Lease Term the Base Rent and Additional Rent in installments as and when the same become due and payable, subject to reduction by any rent actually received by
Landlord as a result of a re-letting of the Premises (net of the reasonable and customary costs of re-letting, including remodeling costs, brokerage commissions and
reasonable attorneys’ fees). Landlord shall exercise commercially reasonable efforts to re-let the Premises to mitigate damages, and Landlord may re-let the
Premises or any part or parts thereof, either in the name of Landlord or otherwise for a term or terms which may, at Landlord’s option, be less than or exceed the period which would otherwise have constituted the balance of the Lease Term and
may grant concessions or free rent. The marketing of the Premises in a manner similar to the manner in which Landlord markets other premises within Landlord’s control within the Building shall be deemed to have

  
 29 

 
satisfied Landlord’s obligation to use “reasonable efforts” hereunder. In no event shall Landlord be required to (i) solicit or entertain negotiations with any other
prospective tenant for the Premises until Landlord obtains full and complete possession of the Premises (including, without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant), (ii) relet the
Premises before leasing other vacant space in the Building, or (iii) lease the Premises for a rental less than the current fair market rent then prevailing for similar office space in the Building. The good faith failure of Landlord to re-let the Premises or any part or parts thereof, or, if the Premises are re-let, the good faith failure to collect the rents due under such
re-letting, shall not release or affect Tenant’s liability for damage so long as Landlord does not act arbitrarily or capriciously. Any suit brought to collect the amount of the deficiency for any month
or other period shall not prejudice in any way the right of Landlord to collect the deficiency for any subsequent month or period by a similar proceeding. Landlord, at Landlord’s option, may make such alterations, repairs, replacements and
decorations on the Premises as Landlord in Landlord’s sole but good faith business judgment considers advisable and necessary for the purpose of re-letting the Premises, and the making of such alterations
or decorations shall not operate or be construed to release Tenant from liability hereunder. 
 (c)    If, pursuant to
Section 12.2(a), Landlord terminates this Lease, Tenant shall forthwith pay to Landlord as damages, in addition to all sums which were due prior to the date of such termination, a sum equal to the amount by which the Base Rent and Additional
Rent for the remainder of the Lease Term exceeds the fair rental value of the Premises for the remainder of the Lease Term, discounted to present value using a then market rate of interest as reasonably determined by Landlord. For the purposes of
computing damages payable pursuant to this Section 12.2(c), the Additional Rent with respect to Taxes, Insurance Costs and Operating Costs for the remainder of the Lease Term will be assumed to be the product of such Additional Rent for the
most recently ended fiscal, calendar or lease year, as the case may be, times the number of years remaining of the Lease Term. For the purposes of this Article, if Landlord elects to require Tenant to pay liquidated damages in accordance with this
Section 12.2 the total rent shall be computed by assuming the Tenant’s Share of Taxes, Operating Expenses and Insurance Costs under this Lease to be the same as were payable for the twelve (12) calendar months (or if less than twelve
(12) calendar months have been elapsed since the date hereof, the partial year) immediately preceding such termination of re-entry. 

(d)    Tenant shall be responsible to Landlord for all expenses which Landlord may incur in connection with the
enforcement of Landlord’s rights after an Event of Default, including, without limitation, reasonable legal expenses, attorneys’ fees, brokerage fees, reasonable decommissioning costs and expenses and the cost of putting the Premises in
good order or preparing the same for rental. 
 (e)    Tenant, for itself and any and all persons claiming through or
under Tenant, including its creditors, upon the termination of this Lease and of the term of this Lease in accordance with the terms hereof, or in the event of entry of judgment for the recovery of the possession of the Premises in any action or
proceeding, or if Landlord shall enter the Premises by process of law or otherwise, hereby waives any right of redemption provided or permitted by any statute, law or decision now or hereafter in force, and does hereby waive, surrender and give up
all rights or privileges which it or they may or might have under and by reason of any present or future law or decision, to redeem the Premises or for a continuation of this Lease for the term of this Lease hereby demised after having been
dispossessed or ejected therefrom by process of law, or otherwise. 
 Section 12.3 Reimbursement of Landlord. Upon the
occurrence of an Event of Default, Tenant will, in addition to paying Landlord all amounts due under the terms and provisions of this Lease, including, without limitation, Section 12.9, reimburse Landlord for all reasonable expenses incurred by
Landlord in collecting such rent or in obtaining possession of, or in re-letting the Premises, or in defending any action, including expenses for reasonable counsel fees and commissions. If on termination of
this Lease by expiration or otherwise, Tenant shall fail to remove any of its property from the Premises as provided for herein, Landlord shall be authorized, in its sole option, and in Tenant’s name and on its behalf, either (a) to cause
such property to be removed and placed in storage for the account and at the expense of Tenant; or (b) to sell such property at public or private sale, with or without notice, and to apply the proceeds thereof, after the payment of all expenses
of removal, storage and sale, to the indebtedness, if any, of Tenant to Landlord, the surplus, if any, to be paid to Tenant. All sums payable by Tenant under this Article XII shall be deemed Additional Rent. 

  
 30 

 Section 12.4 Landlord’s Right to Perform Tenant’s Covenants. If Tenant
shall at any time fail to make any payment or perform any other act on its part to be made or performed as in this Lease provided, Landlord, in its sole discretion may after due notice to, or demand upon, Tenant, make any payment or perform any
other act on the part of Tenant to be made and performed as in this Lease provided, in such manner and to such extent as Landlord may reasonably deem desirable, and in exercising any such rights, Landlord may pay necessary and incidental costs and
expenses, employ counsel, and incur and pay reasonable attorneys’ fees. The making of any such payment or the performing of any other act by Landlord pursuant to this Article shall not waive, or release Tenant from, any obligations of Tenant in
this Lease contained. All sums so paid by Landlord and all reasonably necessary and incidental costs and expenses in connection with the performance of any such act by Landlord shall, except as otherwise in this Lease expressly provided, be payable
to Landlord on demand, and Tenant covenants to pay any such sum or sums promptly, and Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the
non-payment thereof by Tenant as in the case of default by Tenant in the payment of the Base Rent. Whenever practicable, Landlord, before proceeding as provided in this Section 12.4, shall give Tenant
notice in writing of the failure of Tenant which Landlord proposes to remedy, and shall allow Tenant such length of time as may be reasonable in the circumstances, consistent with any grace periods contained herein, but not exceeding ten days from
the giving of notice, to remedy the failure itself and, if Tenant shall not remedy the failure in the time so allowed, Landlord shall be deemed to have given “due notice” and may proceed as provided in this Section 12.4; provided that
nothing in this Section shall prevent Landlord from acting without notice to Tenant in case of any emergency wherein there is danger to property or person or where there may exist any violation of Legal Requirements including but not limited to the
presence of Hazardous Materials, in which event no notice shall be required. 
 Section 12.5 Cumulative Remedies. The specified
remedies to which Landlord may resort under the terms of this Lease, or under the provisions of applicable law, are cumulative and not intended to be exclusive of any other remedies or means of redress to which Landlord may be lawfully entitled in
case of any breach or threatened breach by Tenant of any provisions of this Lease. The failure of Landlord to insist in any one or more cases upon the strict performance of any of the covenants of this Lease or to exercise any option contained
herein shall not be construed as a waiver or a relinquishment for the future of such covenant or option. Receipt by Landlord of any Base Rent or Additional Rent payment with knowledge of the breach of any covenants hereof shall not be deemed a
waiver of such breach. No waiver by Landlord of any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by it. In addition to the other remedies provided in this Lease, Landlord shall be entitled to
restraint by injunction of any violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease. 

Section 12.6 Expenses of Enforcement. Tenant shall pay all reasonable expenses and reasonable attorneys’ fees incurred by
Landlord in enforcing any obligation or any remedies hereunder including, without limitation, in connection with collection of Base Rent or Additional Rent, recovery by Landlord of the Premises, or in any litigation in which Landlord shall become
involved by reason of any act or negligence of Tenant’s Invitees or any breach of this Lease by Tenant. Landlord shall pay ail reasonable expenses and reasonable attorneys’ fees incurred by Tenant in enforcing any obligation or any
remedies hereunder including any litigation in which Tenant shall become involved by reason of any act or negligence of Landlord or any breach of this Lease by Landlord. 

Section 12.7 Landlord’s Default. Landlord shall not be deemed to be in default hereunder unless such default shall remain
uncured for more than 30 days following written notice from Tenant to Landlord specifying the nature of such default, or such longer period as may be reasonably required to correct such default. Landlord’s liability to keep, maintain, and
repair shall always be limited to the cost of making such repair or accomplishing such maintenance or repair. In no event whatsoever shall Landlord be liable for consequential or any indirect damages. The provisions of this Section 12.7 are
further subject to the provisions of Articles X and XI dealing with eminent domain and fire and other casualty, and Section 6.3 dealing with interruption of services. Tenant hereby acknowledges and agrees that the obligations of

  
 31 

 
Tenant hereunder shall be separate and independent covenants and agreements, that the obligations of Tenant hereunder, including, without limitation the obligation to pay Base Rent and Additional
Rent and other sums due hereunder, shall continue unaffected, unless the requirement to pay or perform the same shall have been terminated or abated pursuant to an express provision of this Lease. Landlord and Tenant each acknowledges and agrees
that the independent nature of the obligations of Tenant hereunder represents fair, reasonable, and accepted commercial practice with respect to the type of property subject to this Lease. 

Section 12.8 Limitation of Landlord’s Liability. The obligations of Landlord hereunder shall be binding upon Landlord and
each succeeding owner of Landlord’s interest hereunder only during the period of such ownership, and Landlord and each succeeding owner shall have no liability whatsoever except for its obligations during each such respective period. Tenant
agrees for itself and each succeeding holder of Tenant’s interest, or any portion thereof, hereunder, that any judgment, decree or award obtained against Landlord or any succeeding owner of Landlord’s interest, which is in any manner
related to this Lease, the Premises or Tenant’s use and occupancy of the Premises or the Common Areas, or the remainder of the Project, whether at law or in equity, shall be satisfied out of Landlord’s equity in the land and buildings then
comprising the Project to the extent then owned by Landlord and such succeeding owner, and further agrees to look only to such assets (or proceeds thereof) and to no other assets of Landlord, or such succeeding owner, for satisfaction. Neither
Landlord nor any Person executing this Lease on behalf of Landlord, nor any partner, limited or general, or any officer, director, employee, member, trustee, beneficiary, or owner of Landlord, nor any subsequent Landlord, or any partner, limited or
general, or any officer, director, employee, member, trustee, beneficiary, or owner of any subsequent Landlord shall have any personal liability hereunder. The remedies provided to Tenant in this Lease are exclusive, and Landlord will not be liable
under any theory of recovery, whether based on contract, tort or otherwise. 
 Section 12.9 Late Payment and Administrative
Expense. If Tenant shall fail to pay Base Rent, Additional Rent or other charges after the same become due and payable under this Lease, such unpaid amounts shall bear interest from the due date thereof to the date of payment at the lesser of
(a) a per annum rate equal to 3% plus the prime rate of Bank of America (or any successor) in effect on the day the payment became due and subject to change thereafter or (b) the maximum rate permitted by applicable law (“Interest
Payment”). In addition, if Landlord is required to redeposit any check which is returned for insufficient funds or if Tenant shall fail to pay Base Rent, Additional Rent or other charges on or before the date on which the same become due
and payable, then Tenant shall also pay to Landlord an administrative expense charge (“Administrative Expense”) of 5% of the amount thereof for each calendar month or part thereof after the due date of such payment until such
payment is received by Landlord. The provisions herein for Interest Payment and Administrative Expense shall not be construed to relieve Tenant of the obligation to pay Base Rent, Additional Rent and all other charges when due under this Lease and
shall be in addition to and not in limitation of Landlord’s other remedies as provided for in this Lease. 
 ARTICLE XIII

 MISCELLANEOUS PROVISIONS 

Section 13.1 Brokers. Each party represents that it has not dealt with any Person in connection with the Premises or the
negotiation or execution of this Lease other than officers, employees and attorneys of Landlord and Brokers. Each party shall indemnify and save harmless the other from and against all claims, liabilities, costs and expenses incurred as a result of
any breach of the foregoing representation. The fees payable to Brokers for this Lease shall be payable by Landlord subject to and in accordance with the terms of separate agreements between Landlord and Brokers. 

Section 13.2 Quiet Enjoyment. Tenant shall, upon paying all Base Rent and Additional Rent due hereunder and observing and
performing all of the terms, covenants and conditions on Tenant’s part to be observed and performed, peaceably and quietly have and hold the Premises without hindrance or molestation by any Person or Persons lawfully claiming by, through or
under, Landlord, subject, however, to the terms of this Lease. 

  
 32 

 Section 13.3 Tenant’s Request for Landlord’s Action. In the event that
at Tenant’s request Landlord takes any action which is not required of Landlord pursuant to this Lease, Tenant shall pay as Additional Rent Landlord’s reasonable attorneys’ fees, expenses and disbursements in connection with such
action, with payment to be made by Tenant within 30 days after billing therefor by Landlord. 
 Section 13.4 Notices. Any
notice, demand, request or statement required or intended to be given or delivered under the terms of this Lease shall be in writing, shall be addressed to the party to be notified at the address or addresses set forth in the Summary of Basic Terms
or at such other address in the continental United States as each party may designate for itself from time to time by notice hereunder, and shall be deemed to have been given, delivered or served upon the earliest of (a) three days following
deposit in the U.S. Mail, with proper postage prepaid, certified or registered, return receipt requested, (b) the next Business Day after delivery to a regularly scheduled overnight delivery carrier with delivery fees either prepaid or an
arrangement, satisfactory with such carrier, made for the payment of such fees, or (c) receipt of notice of delivery if given by e-mail or personal delivery. 

Section 13.5 Waiver of Subrogation. Landlord and Tenant hereby release each other, to the extent of their respective insurance
coverages, from any and all liability for any loss or damage caused by fire, any of the extended coverage casualties, or other casualties insured against, even if such fire or other casualty shall be brought about by the fault or negligence of the
party benefited by the release or its agents, provided that this release shall be in force and effect only with respect to loss or damage occurring during such time as the policies of fire, extended coverage and other insurance, maintained by the
releasing party shall contain a clause, or be subject to a statutory provision, to the effect that such release shall not affect said policies or the right of the releasing party to recover thereunder. Tenant’s fire, extended coverage, and
other insurance policies will include such a clause. To the extent that Tenant is a self-insurer with respect to personal property, the provisions of Section 7.8 shall be applicable. 

Section 13.6 Entire Agreement; Execution; Time of the Essence and Headings and Table of Contents. This Lease together with all
Exhibits referred to herein and the Summary of Basic Terms, sets forth the entire agreement between the parties hereto and cannot be modified or amended, except in a writing duly executed by the respective parties. This Lease, together with all
Exhibits referred to herein and the Summary of Basic Terms, supersedes all previous written and oral negotiations, understandings and agreements regarding the subject matter of this Lease. Neither Landlord nor any Person acting on behalf of Landlord
has made any representations to Tenant on which Tenant has relied in entering into this Lease except any representations expressly stated in this Lease. This Lease is executed as a sealed instrument and in multiple counterparts, all copies of which
are identical, and any one of which is to be deemed to be complete in itself and may be introduced in evidence or used for any purpose without the production of any other copy. Time is of the essence with respect to the obligations of Tenant and
Landlord to be performed within a specific time frame in this Lease. The headings throughout this Lease and the Table of Contents are for convenience of reference only, and shall in no way be held or deemed to define, limit, explain, describe,
modify or add to the interpretation, construction or meaning of any provision of this Lease. 
 Section 13.7 Partial Invalidity.
If any term or condition of this Lease or its application to any Person or circumstance shall to any extent be in violation of or unenforceable under any law, rule, regulation or order (including any court order) now existing or hereafter enacted or
entered by any court or other governmental entity having competent jurisdiction (including after all appeals therefrom), the remainder of this Lease, or the application of such term or condition to Persons or circumstances other than those as to
which it is invalid or unenforceable, shall not be affected thereby and shall be enforceable to the fullest extent not prohibited by law. 

Section 13.8 No Waiver. No assent, express or implied, by Landlord to any breach of any agreement or condition herein contained on
the part of Tenant to be performed or observed, and no waiver, express or implied, of any such agreement or condition shall be deemed to be a waiver of or an assent to any succeeding breach of the same or any other agreement or condition; the
acceptance by Landlord of Base Rent or Additional Rent due hereunder (whether such payment is made by Tenant or another Person), or silence by Landlord as to any breach, shall not be construed as waiving any of Landlord’s rights hereunder
unless such waiver shall be in writing. No payment by Tenant or acceptance by Landlord of a 

  
 33 

 
lesser amount than shall be due Landlord from Tenant shall be deemed to be anything but payment on account, and the acceptance by Landlord of a check for a lesser amount with an endorsement or
statement thereon, or upon a letter accompanying said check, that said lesser amount is payment in full shall not be deemed an accord and satisfaction, and Landlord may accept said check without prejudice to recover the balance due or pursue any
other remedy. 
 Section 13.9 Holdover; Waiver of Consequential Damages. If Tenant remains in the Premises beyond the expiration
of this Lease at the end of the Lease Term, or sooner following an early termination as provided for herein, such holding over shall not be deemed to create any tenancy, but Tenant shall be a daily Tenant at sufferance only subject to all of
Tenant’s obligations set forth herein, but at a Base Rent equal to one and one-half (1%) times the Base Rent then most recently in effect and Additional Rent and other charges provided for under this
Lease, with such Base Rent and Additional Rent to be charged on a monthly basis for each calendar month or portion thereof for which Tenant holds over, without proration for a partial calendar month. The acceptance of a purported rent check
following termination shall not constitute the creation of a tenancy at will, it being agreed that Tenant’s status shall remain that of a daily Tenant at sufferance, at the aforesaid daily rate. Tenant shall also pay to Landlord all damages, if
any, sustained by reason of any such holding over in excess of 30 days. Otherwise, such holding over shall be on the terms and conditions set forth in this Lease as far as applicable. In addition, Tenant shall save the Landlord Parties harmless and
will exonerate, defend and indemnify the Landlord Parties from and against any and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the Term of this Lease. 

Except as set forth in the immediately preceding paragraph, Tenant shall not be liable hereunder for consequential, punitive or special
damages. 
 Section 13.10 When Lease Becomes Binding. The submission of this document for examination and negotiation does not
constitute an offer to lease or a reservation or an option for the Premises, and this document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant and the receipt by Landlord of the Security
Deposit. All negotiations, considerations, representations and understandings between Landlord and Tenant are incorporated herein and may be modified or altered only by agreement in writing between Landlord and Tenant, and no act or omission of any
employee or agent of Landlord shall alter, change or modify any of the provisions hereof. 
 Section 13.11 Recordation. Tenant
shall not record this Lease with any registry of deeds or land court, and any such recordation will be void and constitute an Event of Default under this Lease. 

Section 13.12 As Is. Subject to performance of Landlord’s Work, Tenant represents to Landlord that it has leased the Premises
after a full and complete examination of the same, and by its execution and delivery of this Lease, Tenant hereby acknowledges that neither Landlord, nor Landlord’s agents, has made any representation or promises with respect to the Premises,
the Building, or the land upon which it stands, and no rights, easements or licenses are acquired by Tenant, by implication or otherwise, except as may be set forth expressly in this Lease. 

Section 13.13 Financial Statements; Certain Representations and Warranties of Tenant. On an annual basis and subject to
Section 13.14 below (or more frequently if requested by Landlord in connection with a financing or sale of the Property), Tenant shall provide to Landlord, any actual or potential mortgagee and any actual or potential ground lessor or any
representative of any of the foregoing, copies of Tenant’s annual financial statements (audited if available), certified as true and correct by the president or chief financial officer of Tenant. Tenant represents and warrants to Landlord, its
successors and assigns that; (a) all financial statements of Tenant previously provided to Landlord have been prepared in accordance with GAAP, were true, complete and correct as of their respective dates and fairly and accurately reflect the
financial condition of Tenant; (b) there has been no material adverse change in the financial condition of Tenant subsequent to the date(s) of such financial statements; (c) all financial statements of Tenant provided to Landlord after the
date hereof will be prepared in accordance with GAAP, will be true, complete and correct as of their respective dates and will fairly and accurately reflect the financial conditions of the Tenant; (d) Tenant is a corporation duly organized,

disclosure of such information may only be made if the other party consents in writing prior to any such disclosure, and (c) any information or material provided by Tenant to Landlord that is available in the public domain shall not be
considered Confidential Information, including without limitation, any publicly available construction blueprints and plans. In addition, each party may, but shall not be required to, condition its disclosure of Confidential Information to the other
party upon such other party’s execution of a commercially reasonable non-disclosure agreement.

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED
PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934
The following is a summary of the rights of our common and preferred stock and some of the provisions of our amended and restated certificate of incorporation, our amended and restated bylaws, and certain provisions of Delaware General Corporation Law. The descriptions herein are qualified in their entirety by our amended and restated certificate of incorporation, our amended and restated bylaws, copies of which have been filed as exhibits to our Annual Report on Form 10-K of which this description is a part, as well as certain provisions of Delaware General Corporation Law. References to the terms “we,” “our,” and “us” refer to C3.ai, Inc., unless the context otherwise requires.
General
Our authorized capital stock consists of the following:
•1,000,000,000 shares designated as Class A common stock, par value $0.001 per share;
•3,500,000 shares designated as Class B common stock, par value $0.001 per share; and
•200,000,000 shares designated as preferred stock, par value $0.001 per share.
As of April 30, 2021, only our Class A common stock was registered under Section 12 of the Securities Exchange Act of 1934, as amended, or the Exchange Act.
Class A and Class B Common Stock
All authorized but unissued shares of our Class A common stock and Class B common stock are available for issuance by our board of directors without any further stockholder action, except as required by the listing standards of the New York Stock Exchange. Our amended and restated certificate of incorporation provides that, except with respect to voting rights and conversion rights, our Class A common stock and Class B common stock are treated equally and identically.
Voting Rights
Holders of Class A common stock are entitled to one vote per share on all matters to be voted upon by our stockholders, and holders of Class B common stock are entitled to 50 votes per share on all matters to be voted upon by our stockholders. Holders of Class A common stock and Class B common stock generally vote together as a single class on all matters submitted to a vote of our stockholders, unless otherwise required by Delaware law or our amended and restated certificate of incorporation. Delaware law could require either holders of Class A common stock or Class B common stock to vote separately as a single class in the following circumstances, among others:
•if we were to seek to amend our amended and restated certificate of incorporation to increase or decrease the number of authorized shares of a class of our capital stock (other than our preferred stock), then that class would be required to vote separately to approve the proposed amendment;
•if we were to seek to amend our amended and restated certificate of incorporation to increase or decrease the par value of a class of our capital stock, then that class would be required to vote separately to approve the proposed amendment; and

•if we were to seek to amend our amended and restated certificate of incorporation in a manner that alters or changes the powers, preferences, or special rights of a class of our capital stock in a manner that affected its holders adversely, then that class would be required to vote separately to approve the proposed amendment.
As a result, in these instances, the holders of a majority of shares of Class A common stock entitled to vote could defeat an amendment to our amended and restated certificate of incorporation.
Our amended and restated certificate of incorporation does not provide for cumulative voting for the election of directors.
Dividend Rights
Holders of Class A common stock and Class B common stock are entitled to ratably receive dividends if, as and when declared from time to time by our board of directors at its own discretion out of funds legally available for that purpose, after payment of dividends required to be paid on outstanding preferred stock, if any.
Right to Receive Liquidation Distributions
Upon our dissolution, liquidation or winding-up, the assets legally available for distribution to our stockholders are distributable ratably among the holders of Class A common stock and Class B common stock, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights and payment of liquidation preferences, if any, on any outstanding shares of preferred stock.
Conversion
Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock. In addition, each share of Class B common stock will convert automatically into one share of Class A common stock upon any transfer, whether or not for value, except certain transfers to entities, to the extent the transferor retains sole dispositive power and exclusive voting control with respect to the shares of Class B common stock, and certain other transfers described in our amended and restated certificate of incorporation. All outstanding shares of Class B common stock will convert into shares of Class A common stock upon the earliest of (1) the date that is six months following the death or incapacity of Mr. Siebel, (2) the date that is six months following the date that Mr. Siebel is no longer providing services to us as an officer, employee, director or consultant, (3) the 20-year anniversary of the date of the closing of our initial public offering, and (4) the date specified by the holders of a majority of the then outstanding shares of Class B common stock, voting as a separate class.
Other Matters
The Class A common stock and Class B common stock have no preemptive rights pursuant to the terms of our amended and restated certificate of incorporation and our amended and restated bylaws. There are no redemption or sinking fund provisions applicable to the Class A common stock and Class B common stock. 
Preferred Stock
Our board of directors may, without further action by our stockholders, fix the rights, preferences, privileges, and restrictions of up to an aggregate of 200,000,000 shares of preferred stock in one or more 
2

series and authorize their issuance. These rights, preferences, and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of our common stock. The issuance of our preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change of control or other corporate action. 
No shares of preferred stock are currently outstanding.
Registration Rights
We are party to an amended and restated registration rights agreement, or the Registration Rights Agreement, that provides demand, piggyback and shelf registration rights to certain holders of our common stock. The registration of shares of our common stock by the exercise of registration rights described below would enable the holders to sell these shares without restriction under the Securities Act of 1933, as amended, or the Securities Act, when the applicable registration statement is declared effective. 
The demand, piggyback and shelf registration rights provided pursuant to the Registration Rights Agreement will expire three years after the completion of our initial public offering or, with respect to any particular stockholder, (1) the time that such stockholder can sell all of its shares entitled to registration rights under Rule 144 of the Securities Act during any 90-day period or (2) the time that such stockholder owns less than 1% of our outstanding Class A common stock. We will pay the registration expenses, not to exceed $25,000, of the shares registered by the demand, piggyback and shelf registrations conducted pursuant to the Registration Rights Agreement.
Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws
Some provisions of Delaware law, our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that could make the following transactions more difficult: (1) an acquisition of us by means of a tender offer; (2) an acquisition of us by means of a proxy contest or otherwise; (3) or the removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions which provide for payment of a premium over the market price for our shares.
These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.
Dual Class Stock
As described above in “—Class A and Class B Common Stock—Voting Rights,” our amended and restated certificate of incorporation establishes for a dual class common stock structure, which provides our founders with significant influence over all matters requiring stockholder approval, including the 
3

election of directors and significant corporate transactions, such as a merger or other sale of our company or our assets.
Stockholder Meetings
Our amended and restated bylaws provide that a special meeting of stockholders may be called only by our chairman of the board, chief executive officer or president, or by a resolution adopted by a majority of our board of directors.
Requirements for Advance Notification of Stockholder Nominations and Proposals
Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals to be brought before a stockholder meeting and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors.
Elimination of Stockholder Action by Written Consent
Our amended and restated certificate of incorporation and amended and restated bylaws eliminate the right of stockholders to act by written consent without a meeting.
Staggered Board
Our board of directors is divided into three classes. The directors in each class serve for a three-year term, with one class elected each year by our stockholders. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us because it generally makes it more difficult for stockholders to replace a majority of the directors.
Removal of Directors
Our amended and restated certificate of incorporation provides that no member of our board of directors may be removed from office by our stockholders except for cause and, in addition to any other vote required by law, upon the approval of not less than two thirds of the total voting power of all of our outstanding voting stock then entitled to vote in the election of directors.
Stockholders Not Entitled to Cumulative Voting
Our amended and restated certificate of incorporation does not permit stockholders to cumulate their votes in the election of directors. Accordingly, the holders of a majority of the outstanding shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.
Delaware Anti-Takeover Statute
We are subject to Section 203 of the Delaware General Corporation Law, which prohibits persons deemed to be “interested stockholders” from engaging in a “business combination” with a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested 
4

stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors.
Choice of Forum
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, employees, or agents to us or our stockholders; (3) any action asserting a claim against us arising pursuant to any provision of the General Corporation Law of the State of Delaware or our certificate of incorporation or bylaws; (4) any action to interpret, apply, enforce, or determine the validity of our certificate of incorporation or bylaws; or (5) any action asserting a claim governed by the internal affairs doctrine. The provisions would not apply to suits brought to enforce a duty or liability created by the Securities Act, the Exchange Act, or any other claim for which the U.S. federal courts have exclusive jurisdiction. However, as Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act, and an investor cannot waive compliance with the federal securities laws and the rules and regulations thereunder, there is uncertainty as to whether a court would enforce such a provision. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated certificate of incorporation provides that the U.S. federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.
While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our amended and restated certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.
These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive-forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.
Amendment of Charter Provisions
The amendment of any of the above provisions, except for the provision making it possible for our board of directors to issue preferred stock, would require approval by holders of at least two-thirds of the total voting power of all of our outstanding voting stock.
