A. Conventus Partners, LLC (“Prime Landlord’) is ground lessee of the real property commonly known as 1001 Main Street, Buffalo, New York (the “Property”) which Property is described on Exhibit A attached hereto and made a part hereof.

B. Landlord, as tenant, leases certain space, including the Leased Premises (as defined below in Section 1), under that certain Lease Agreement, as amended, with Prime Landlord, dated as of December 4, 2014 (“Prime Lease”).

C. In accordance with that certain Agreement for Medical Technology Research, Development, Innovation, and Commercialization Alliance, effective as of May 1, 2015, between Landlord and Tenant (“Alliance Agreement”), Landlord desires to sublease to Tenant and Tenant desires to sublease from Landlord the Leased Premises on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and of the representations and agreements contained in this Sublease Agreement, the parties agree as follows:

1. Leased Premises. Landlord hereby leases to Tenant and Tenant agrees to lease from Landlord approximately Fifty-One Thousand (51,000) rentable square feet (the “Leased Premises”), including 14,000 square feet for a formulation testing lab and pilot plan, 2,000 square feet for a chemistry lab for a biological and analytical testing lab, 24,000 square feet for office and training space, 3,000 square feet for mechanicals, and related infrastructure, located on the sixth (6^th) floor of the building (“Building”) located on the Property, upon the terms and conditions set forth in this Sublease Agreement, which Leased Premises are depicted with more particularity on Exhibit B attached hereto.

The net rentable area shall include a common area factor which shall be included in the calculation of Base Rent (hereinafter defined), and Additional Rent (hereinafter defined) for the Leased Premises.

In determining the number of rentable or useable square feet, all measurements shall be performed pursuant to the standards and methods of measurement set forth by the Building Owners and Managers Association International (BOMA) Office Buildings: Standard Methods of Measurement and Calculating Rentable Area (2010) (“BOMA 2010”). If the amount of rentable square feet of the Leased Premises is adjusted by Landlord and Prime Landlord under the Prime Lease, then Landlord and Tenant shall amend this Sublease Agreement in accordance with the adjustment under the Prime Lease.

2. Landlord’s Work. Consistent with Sections 5.1(e)-(f) and Exhibit C of the Alliance Agreement, Landlord’s obligation with respect to the Leased Premises shall be as set forth on Exhibit C, attached hereto and incorporated herein. Landlord will use its best efforts to have the office space included within the Leased Premises substantially completed no later than October 1, 2015 and the lab/technical space included within the Leased Premises substantially completed no later than March 31, 2016. In accordance with Section 5.1(g) of the Alliance Agreement, under no circumstances will Landlord’s costs for the Premises and the Laboratory Equipment identified in Exhibit C exceed $25 million in the aggregate.

3. Term. The term of this Sublease Agreement shall be for ten (10) Lease Years (the “Term”), commencing on August 1, 2015 (“Commencement Date”) and ending on the last day of the tenth (10^th) Lease Year unless sooner terminated as permitted in this Lease. Tenant shall begin to pay Landlord Base Rent and Additional Rent for the Leased Premises on August 1, 2015 (the “Rent Commencement Date”). If fit-up for the Leased Premises is not completed by August 1, 2015, then Tenant will be allowed to begin moving into the Leased Premises while fit-up is being finalized. The term “Lease Year” as used herein shall mean a period of twelve (12) consecutive full calendar months (except for the first Lease Year, which may be longer). The first Lease Year shall commence on the Commencement Date. The first Lease Year shall expire at midnight on the last day of the twelfth (12th) full month following Rent Commencement Date. Succeeding Lease Years shall each commence on the first (1st) day following the end of the preceding Lease Year. Tenant shall have the option to extend the Term of the Sublease Agreement for an additional ten (10) year period. This option to extend the Term may be exercised by Tenant by providing written notice to Landlord at least forty-eight months prior to the end of the Term. If Tenant does not timely exercise its option to extend the Term of this Sublease Agreement, or if an event of default has occurred and remains uncured by Tenant, then such option is null and void and be of no further force or effect. In no event shall the Term of this Sublease Agreement extend beyond the term of the Prime Lease.

Tenant shall occupy, use and operate the Leased Premises solely for uses permitted under the terms of the Ground Lease (as hereinafter defined), and no other purposes (collectively the “Permitted Uses”). Tenant shall not use or allow the Leased Premises or any part thereof to be used or occupied for an unlawful purpose or in violation of any certificate of occupancy or completion affecting the Leased Premises or in any manner which may constitute a nuisance, public or private, or make void or voidable any insurance then in force with respect thereto.

Tenant shall at its own cost and expense promptly observe and comply with all laws, ordinances, requirements, orders, directives, rules and regulations of the federal, state, county, or municipal governments and of all governmental authorities (collectively, “Laws”) affecting its occupancy of and conduct of its business at the Leased Premises, whether the same are in force at the commencement of the term of this Sublease Agreement or may be in the future passed, enacted or directed.

Tenant covenants and agrees to pay to Landlord base rent (“Base Rent”) as follows:

If Tenant’s option to extend the term is exercised Tenant covenants and agrees to pay to Landlord base rent (“Base Rent”) as follows:

One-twelfth of annual Base Rent and Additional Rent shall be paid in advance by Tenant to Landlord without notice on the first day of each month without offset or deduction to Landlord, in its name, at 257 Fuller Road, Albany, New York 12203, or to such other address or payee as Landlord may designate in writing. In the event that the Commencement Date is other than on the first of the month, then Base Rent and Additional Rent for the balance of the month shall be pro-rated accordingly and paid on or prior to the Commencement Date and the full term of the Lease shall commence on the first day of the following month.

Tenant shall be required to pay any applicable taxes levied against rental payments made hereunder including, but not limited to, any sales, use or similar tax imposed on rent, if any.

Tenant agrees to pay all rents and other charges under the terms of this Lease when they are due and payable. Any Base Rent or Additional Rent or other sums due and payable pursuant to this Lease remaining unpaid five (5) days after due date or any other charges remaining unpaid ten (10) days after receipt of invoice shall accrue interest at the Interest Rate as defined in Section 12 below from such tenth (10^th) day, until paid.

(a) Beginning effective as of the Rent Commencement Date, Tenant shall pay to Landlord as Additional Rent its pro rata share of (i) all state and local real estate taxes and assessments (including any sewer charges included in the tax bill), and payments in lieu thereof, and all other charges and assessments imposed upon the Property, (ii) premiums for fire, casualty, rent, liability and other insurance maintained by Landlord, including, without limitation, coverage for such perils as may be reasonably required by Landlord’s lender as may exist from time to time (“Mortgagee”) or as is desired by Landlord and is, in Landlord’s opinion, prudent for the Building and Property and (iii) the costs of all services performed by Landlord, including, without limitation, those set forth in Exhibit D [(i), (ii) and (iii) collectively being “Operating Costs”]. Operating Costs shall include a management fee of not more than five percent (5%). If Landlord or Tenant secures a reduction or exemption from real property taxes related solely to the Leased Premises, Tenant will be solely entitled to such reduction or abatement. Any other reduction or

abatement shall be allocated among all tenants of the Building proportionately in accordance with their respective rentable square footage.

(b) Beginning effective as of the Commencement Date and thereafter prior to December 15th of each calendar year Landlord shall deliver to Tenant Landlord’s reasonable estimate of the aggregate amount which will be incurred by Landlord for the Operating Costs during the forthcoming calendar year or, in the first or last year of the term, the applicable part thereof. Tenant shall pay as Additional Rent by the first day of each month of a full or partial calendar year during the term of this Sublease Agreement, that fraction of Tenant’s pro rata share for such full or partial calendar year, the numerator of which shall be one (1) and the denominator of which shall be twelve or the number of months in the term occurring in such year. As soon as reasonably possible after the completion of each year, but in no event later than April 1st, or, in the final year of the term, as soon as reasonably possible after completion of the term, Landlord shall deliver to Tenant a statement of the actual Operating Costs incurred during such year or applicable part thereof and Tenant shall remit to Landlord within thirty (30) days thereafter the amount, if any, by which Tenant’s pro rata share thereof exceeds the aggregate amount paid by Tenant toward the Operating Costs during such year or applicable part thereof. In the event that the aggregate amount paid by Tenant exceeds its actual pro rata share, Landlord shall credit such excess against Tenant’s estimated payments toward its pro rata share of the Operating Costs for the next year or, except that if in the final Lease Year, the amount paid by Tenant as estimated Operating Costs for such final Lease Year exceeds the actual Operating Costs for such Lease Year, Landlord shall remit such excess to Tenant no later than thirty (30) days after expiration of the final Lease Year.

(c) For purposes of this Section 6, Tenant’s pro rata share of each component of Operating Costs shall be that fraction, the numerator of which is the number of rentable square feet leased by Tenant and the denominator of which is the number of rentable square feet of space in the Building or (if any service is not applicable to all tenants), in that portion of the Building to which such component is applicable. Not less than thirty (30) days prior to the Commencement Date, Landlord shall provide Tenant with written confirmation as to the rentable square footage.

The obligations of the parties relating to Tenant’s payment of its pro rata share of the Operating Costs for the year in which this Sublease Agreement expires shall survive the expiration of this Sublease Agreement.

7. Landlord’s Services.

Premises, including any deposits for meters and/or service. Prime Landlord will install a “check” or “sub” meter at Prime Landlord’s expense to measure Tenant’s water and/or other utility usage within the Leased Premises. Tenant shall pay for water and/or other utility usage as Additional Rent within thirty (30) days after receipt of an invoice from Landlord.

11. Quiet Enjoyment. Landlord covenants that so long as Tenant is not in default hereunder, it shall and may peaceably and quietly have, hold and enjoy the Leased Premises during the Term of this Sublease Agreement and any renewal or extension hereof, subject to the provisions hereof, and any easements, restrictions or agreements to which the Leased Premises are now or shall hereafter be subject.

12. Alterations.

Landlord shall not unreasonably condition, withhold or delay its consent to any Alteration subject to Prime Landlord and/or Mortgagee approval (if such consent is required). In the event that Landlord consents to any Alterations they shall be made at Tenant’s sole expense, and Tenant shall, before making any such Alterations, obtain all permits, approvals and certificates required by any governmental body or agency, and certificates of final approval thereof, and shall deliver promptly duplicates of all such permits, approvals and certificates to Landlord. Tenant agrees to carry, or to cause its contractor and subcontractors to carry, such workers’ compensation, general liability, personal and property damage insurance as Landlord may require. Tenant shall compensate Landlord for Landlord’s reasonable out-of-pocket expenses in reviewing any plans and/or specifications for any proposed Alteration, whether or not Landlord consents to the making of same. Any amounts due from Tenant and not paid within thirty (30) days of when invoiced shall incur interest at a rate that is the greater of five percent (5%) above the then prime interest rate or twelve percent (12%) per annum (the “Interest Rate”).

Tenant has no authority or power to cause or permit any lien or encumbrance, created by act or omission of Tenant to be attached to or be placed upon the Property, and any and all liens and encumbrances created by Tenant shall be attached only to its interest in the Leased Premises. Any lien or claim of lien filed against the Leased Premises for work claimed to have been done for, or for materials claimed to have been furnished to, Tenant shall, within thirty (30) days thereafter, be discharged by Tenant, or, at the discretion of Tenant, be bonded pursuant to the New York Lien Law, at Tenant’s expense. If Tenant fails to discharge (or, if permitted, bond) any such liens, then Landlord may, at its option, bond or discharge such lien, and the costs incurred by it in such discharge or bonding shall be due from Tenant on demand and shall bear interest at the Interest Rate.

13. Liability. Tenant shall defend, indemnify and hold harmless Landlord, Prime Landlord, each Mortgagee, the State University of New York Polytechnic Institute, The Research Foundation for the State University of New York (collectively the “Landlord Parties”) and their respective members, agents and employees (collectively, together with the Landlord Parties, the “Indemnified Parties”) from and against all causes of action, claims, damages, losses and expenses, including reasonable attorneys’ fees, resulting from or arising out of bodily injury or death, or damage to or destruction of property, in connection with Tenant’s use or occupancy of the Leased Premises, whether the same be asserted by third parties, Tenant or Tenant’s agents, contractors, employees, invitees or licensees, except, as to Landlord Parties, to the extent caused by Landlord Parties or Landlord Parties’ agents, contractors, employees, invitees or licensees

negligence or intentional misconduct and except, as to a Mortgagee, to the extent caused by the gross negligence or intentional misconduct of such Mortgagee or its agents, contractors, employees, invitees or licensees.

Moreover, Landlord Parties shall not be liable for any damage or injury to any improvements to the Leased Premises made by Tenant, to any property in the Leased Premises, or to Tenant, its agents, contractors, employees, invitees or licensees, arising from any use or condition of the Leased Premises including, without limitation, any injury or damage to persons or property resulting from fire, explosion, collapse, falling plaster, steam, gas, electricity, water, rain or snow or leaks from any part of the Leased Premises or from the pipes, sprinklers, appliances or plumbing works or from the roof, street or subsurface or from any other place or by dampness or by any other cause whatsoever, except, as to Landlord or Prime Landlord, to the extent caused by Landlord or Prime Landlord or their agents, contractors, employees, invitees or licensees negligence or intentional misconduct.

In no event shall Landlord Parties be responsible for consequential or indirect damages.

(a) Tenant shall, at its expense, at all times during the Term of this Sublease Agreement maintain in force a policy or policies with insurance carriers acceptable to Mortgagee of (i) commercial general liability insurance, including contractual liability for Tenant’s obligations of indemnity hereunder and liability for both bodily injury and property damage, against claims for loss of life, bodily injury and property damage occurring in, on or about the Leased Premises or with respect to the operations of Tenant in the Leased Premises, in which the limit of public liability coverage shall be not less than Five Million Dollars ($5,000,000) for combined single limit bodily injury, death, and property damage liability (the “CGL Policy”), (ii) fire, casualty and extended risk insurance covering Tenant’s property and inventory used or stored at the Leased Premises and (iii) worker’s compensation and employer’s liability coverage providing statutorily required benefits. The CGL Policy shall be written on ISO Occurrence form CG 00 01 10/01 or a substitute form providing equivalent coverage and shall cover liability arising from premises and operations, independent contractors, [products-completed operations and personal and advertising injury] and liability assumed under an insured contract (including tort liability of another assumed in a business contract). If the CGL Policy contains a General Aggregate limit, such General Aggregate limit shall apply separately to each location. Landlord Parties shall be included as additional insureds, using ISO Additional Insured Endorsement CG 20 10 11/85 or both CG 20 10 10/01 and CG 20 37 10/01 or equivalent coverage to the additional insured. Coverage for Landlord and each other additional insured shall be as broad as the coverage for Tenant and shall apply as primary insurance on a non-contributory basis before any other insurance or self-insurance, including any deductible, maintained by or provided to Landlord or such other additional insured. Each such policy of insurance shall be written by one or more insurance companies licensed to do business in the State of New York with an AM Best rating of A-VIII or better, shall name Landlord Parties as additional insureds and as the certificate holders thereof, with express waivers of subrogation against Landlord Parties, and shall provide that if the insurers cancel such insurance for any reason whatsoever, or the same is allowed to lapse or expire, or there be any reduction in amount, or any material change is made in the coverage, such

cancellation lapse, expiration, reduction or change shall not be effective as to Landlord Parties until thirty (30) days after receipt by Landlord Parties, as the case may be, of written notice thereof. A copy of each policy and endorsement shall be delivered to Landlord Parties on or before the commencement of the Term of this Sublease Agreement, and copies of all policies and endorsements with respect to all renewals, extensions or replacements thereof shall thereafter be furnished to Landlord Parties at least thirty (30) days prior to the expiration or cancellation of any policies and endorsements which they replace. Tenant shall promptly (and in any event at least five (5) business days prior to the date on which notice is required to be given to the insurer under such policies) notify both Landlord and the insurer in writing of any occurrence which might give rise to a claim under any of the policies required to be maintained by Tenant under this Sublease Agreement. Tenant further agrees to comply in timely fashion with all of the obligations of the insured under each such policy and shall defend, indemnify and hold Landlord Parties harmless from any liability, loss, cost and/or expense suffered or incurred by Landlord Parties as a result of Tenant’s failure to comply with the provisions of this Section 14(a).

(b) Subject to Tenant’s obligation to pay a portion of the cost thereof as a component of the Operating Costs, Prime Landlord will carry the insurance described in item 5 of Exhibit D.

(c) Tenant shall also give Landlord written notice thereof as soon as reasonably practical after it becomes aware of any occurrence or incident which might give rise to a claim against Landlord, including, without limitation, any incident or occurrence within the Leased Premises, the common areas of the Building, the parking lot or elsewhere on the Property.

15. Fire or Other Casualty. In the event that the Leased Premises shall be rendered untenantable by fire or other casualty, Landlord shall be entitled to the proceeds of all applicable insurance maintained by Landlord, and shall, at its option, either (a) terminate this Sublease Agreement by giving Tenant written notice thereof within forty-five (45) days from the later to occur of (i) the date of said damage or destruction or (ii) notification from a Mortgagee that it shall not permit the entire insurance proceeds required for restoration of the Building to be used for such purpose (the “Notice Date”), or (b) repair or replace the Leased Premises to substantially the same condition as prior to the damage or destruction (exclusive of Alterations made by Tenant). If Landlord fails to commence to repair the damage or destruction to the Property within seventy-five (75) days following the date of such damage or destruction, or if the Leased Premises shall not have been substantially replaced or repaired as expeditiously as possible, but in no event more than three hundred sixty five (365) days after the date Landlord commences the repair of such damage or destruction, Tenant may at its option, terminate this Sublease Agreement by giving written notice to Landlord within fifteen (15) days after Landlord’s failure to commence or substantially complete said repairs within the applicable time period. The Base Rent and Additional Rent herein required to be paid shall abate during the period of such untenantability, to the extent that such abatement is covered by Prime Landlord’s rent insurance (or, if Prime Landlord has failed to obtain rent insurance in accordance with item 5 of Exhibit D, to the extent that the abatement would have been covered had Prime Landlord obtained such insurance). Whether or not all or any part of the Leased Premises has been rendered untenantable thereby, Landlord shall also have the option to terminate this Sublease Agreement if such a substantial portion of the Building is damaged by fire or other casualty that Landlord decides not to rebuild. Landlord may exercise its option by giving Tenant written notice thereof on or before the Notice Date.

If the Leased Premises shall be damaged in part by fire or other casualty, but still remain partially tenantable, Landlord shall repair the Leased Premises to substantially the same condition as prior to the damage (exclusive of Alterations made by Tenant). Landlord shall commence repair of the damage or destruction within sixty (60) days from the date of occurrence and complete them with reasonable diligence. During the period of such repairs and restorations, this Sublease Agreement shall continue in full force and effect, and Tenant shall be required to pay the Base Rent and Additional Rent herein reserved, abated by the percentage of area the Leased Premises destroyed as compared to the total area of the Leased Premises, to the extent that such abatement is covered by Prime Landlord’s rent insurance (or, if Prime Landlord has failed to obtain rent insurance in accordance with item 5 of Exhibit D, to the extent that the abatement would have been covered had Prime Landlord obtained such insurance).

16. Eminent Domain. In the event that all or any portion of the Building shall be taken by any governmental authority under the exercise of its right of eminent domain or similar right (or by act in lieu thereof), all right, title and interest in and to any award granted (or sums paid in lieu thereof) shall belong entirely to Landlord, and Tenant hereby assigns to Landlord all of its interest, title or claim, if any, in and to such award (or sums paid in lieu thereof), including, but not limited to, any part of such award attributable to Tenant’s leasehold interest, if any. Nothing contained herein shall preclude Tenant from seeking a separate award from the condemning authority for its relocation expenses and loss of any trade fixtures. In the event of a partial permanent taking, Base Rent and Additional Rent shall be reduced as of the date of such taking by an amount which shall equitably reflect the portion of the Leased Premises taken. If the taking is permanent and of such a substantial nature that (a) it includes more than 25% of the Leased Premises and (b) Tenant cannot conduct its operations in the Leased Premises, Tenant shall have the option, to be exercised by notice in writing to Landlord within thirty (30) days after such taking, of terminating this Sublease Agreement, or, if such taking be total, this Sublease Agreement shall terminate upon the taking. In the event that this Sublease Agreement is terminated pursuant to this Section 16, Tenant shall not have any claim against Landlord for the balance of the unexpired Term of this Sublease Agreement.

17. Subordination; Non-Disturbance. This Sublease Agreement is subject and subordinate to each Mortgage which now encumber or shall hereafter encumber the Property. On the Commencement Date, Prime Landlord shall furnish Tenant with an executed, nondisturbance agreement in the form attached hereto as Exhibit F from the holder of each mortgage encumbering the Building as of such date.

18. Estoppel Certificate. Tenant shall, once annually, upon not less than twenty (20) days’ prior written request by Landlord, execute, acknowledge and deliver to Landlord a written estoppel certificate in such form as Landlord may reasonably require, certifying that this Sublease Agreement is unmodified and in full force and effect (or if there have been modifications that the same is in full force and effect as modified and stating the modifications), the dates to which the Base Rent and Additional Rent have been paid, whether or not to the best of Tenant’s knowledge Landlord is in default hereunder (and if so, specifying the nature of the default), and such other matters as may be required by any Mortgagee or purchaser of the Property, it being intended that any such statement delivered pursuant to this Section 18 may be relied upon by a prospective purchaser of Landlord’s interest or by a Mortgagee, prospective Mortgagee or any assignee or prospective assignee of any Mortgage.

(a) Any one or more of the following events shall constitute an “Event of Default” hereunder:

(i) If any representation or warranty made by Tenant herein or in connection with any Mortgage shall prove to be false, misleading or incorrect in any material respect as of the date made; or

(ii) If Tenant fails to pay any installment of Base Rent or Additional Rent or any other sum to be paid by Tenant within ten (10) days after it is due (any monetary amounts due Landlord pursuant to this Sublease Agreement shall be considered to be Additional Rent); or

(iii) If Tenant fails to remedy a default by it with respect to any of the other covenants, conditions and agreements contained herein or in any rider, exhibit or other addendum hereto, within thirty (30) days after notice thereof; provided, however, that if the default is of such a nature that it cannot reasonably be cured within thirty (30) days, the foregoing shall not be an Event of Default provided that Tenant: (A) within said thirty (30) day period delivers to Landlord written notice of its intention to cure; (B) commences the cure within said thirty (30) day period; and (C) diligently continues to prosecute the cure; and (D) completes the cure prior to the expiration of the applicable grace period under any Mortgage; or

(iv) If Tenant abandons or vacates the Leased Premises or ceases to conduct its business therein; provided, however, that the foregoing shall not constitute an Event of Default if and for so long as Tenant (A) notifies Landlord at least thirty (30) days prior to vacating the Leased Premises; and (B) continues to pay all Base Rent and Additional Rent due hereunder and to perform all of its obligations hereunder in timely fashion; and (C) pays increased insurance premiums, if any, occasioned by its vacating the Leased Premises; and (D) provides reasonable security measures for the Leased Premises reasonably satisfactory to Landlord; or

(v) If (A) a petition in bankruptcy is filed by Tenant, any guarantor, or any other person or entity that becomes liable for the performance of the obligations of Tenant (any guarantor or such other person or entity being a “Responsible Party’’), or (B) proceedings under any bankruptcy or debtor’s relief law or seeking the appointment of a receiver or similar relief are commenced against Tenant or a Responsible Party and are not dismissed within thirty (30) days, or (C) Tenant or a Responsible Party becomes insolvent or admits in writing its inability to pay its debts as they become due, or (D) proceedings are commenced by Tenant or a Responsible Party seeking the appointment of a receiver or similar relief.

(b) If an Event of Default shall occur, Landlord may, in addition to any other right or rights or damages which Landlord may have pursuant to subsection (c) below, serve a written three (3) days’ notice of cancellation of this Sublease Agreement upon Tenant, and upon the expiration of said three (3) days, this Sublease Agreement and the Term hereunder shall end and expire as fully and completely as if the date of expiration of such three (3) days period were the day herein definitely fixed for the end and expiration of this Sublease Agreement and the Term thereof, and Tenant shall then quit and surrender the Leased Premises to Landlord, but Tenant shall remain liable as hereinafter provided. If the three (3) day notice of cancellation shall have been

given, and the Term shall expire as aforesaid, or if any execution or attachment shall be issued against Tenant or any of Tenant’s property whereupon the Leased Premises shall be taken or occupied by someone other than Tenant, then and in either of such events Landlord may, without notice, re-enter the Leased Premises and dispossess Tenant and the legal representative of Tenant or other occupant of the Leased Premises by summary proceedings or otherwise, and remove their effects and hold the Leased Premises as if this Sublease Agreement had not been made, but Tenant shall remain liable hereunder as hereinafter provided.

(c) Should an Event of Default occur Landlord shall have the following options in addition to any rights or remedies set forth above:

(i) Landlord may collect from Tenant any other loss or damage Landlord may sustain by reason of any breach and any diminished value of the Leased Premises resulting from said breach;

(ii) in the event of a breach by Tenant of any of the covenants or provisions of this Sublease Agreement, Landlord shall have the right to enjoin any such; or

(iii) Landlord may cure such default by Tenant at Tenant’s expense, and upon completion of such cure by Landlord Tenant shall, upon demand and as Additional Rent, reimburse Landlord for all costs in connection therewith.

(d) Any and all rights and remedies which Landlord may have under this Sublease Agreement and any rider hereto attached and made a part hereof and at law or in equity shall be cumulative and shall not be deemed inconsistent with each other, and any two or more or all of such rights and remedies may be exercised at the same time. Notwithstanding anything contained herein to the contrary, Landlord hereby agrees, following the occurrence of an Event of Default, to use commercially reasonable efforts to mitigate its damages.

20. Failure to Insist on Strict Performance. The failure of either party to insist, in any one or more instances, upon strict performance of any covenant, term, provision or agreement of this Sublease Agreement shall not be construed as a waiver or relinquishment thereof, but the same shall continue and remain in full force and effect, notwithstanding any law, usage or custom to the contrary. The receipt by Landlord of Base Rent and/or Additional Rent with knowledge of the breach of any covenant or agreement hereunder shall not be deemed a waiver of the rights of Landlord with respect to such breach. No waiver by a party of any provision hereof shall be deemed to have been made unless expressed in writing and signed by the waiving party.

(a) Tenant shall, upon the termination of this Sublease Agreement, by lapse of time or otherwise, return the Leased Premises to Landlord in as good condition as when received, loss by fire or other unavoidable casualty and reasonable wear and tear excepted. It is understood and agreed that the exception made as to “loss by fire or other unavoidable casualty” does not include damages, fires or casualties caused or contributed to by the act or neglect of Tenant, its servants, agents, employees, invitees or licensees, and not compensated for by insurance.

(c) In the event that Landlord, Prime Landlord and Mortgagees whose consent is required consent to any proposed assignment, subletting, encumbrance, or granting of a right of use or occupancy, such consent shall not be deemed to be a consent to any other or further assignment, subletting, encumbrance or granting of a right of use or occupancy.

Notwithstanding the foregoing, Tenant shall not lease retail space to a Subtenant for use as a pharmacy for the retail sale to the public of prescription and non-prescription medications (a “Retail Pharmacy”) only for so long as Landlord or a wholly owned subsidiary of Landlord solely owns and operates such Retail Pharmacy and such Retail Pharmacy is open for

business to the general public within the Premises. Landlord must notify Tenant in writing prior to the commencement of construction of the Tenant’s Improvements whether or not it intends to operate a Retail Pharmacy within the Premises. In the event the Retail Pharmacy is not owned and operated solely by Landlord or a wholly owned affiliate of Landlord, Landlord’s right to operate a Retail Pharmacy within the Premises shall immediately terminate and the Retail Pharmacy operated by Landlord shall immediately close.

C., or any subsidiary professional corporation of General Physicians, P. C. or an affiliate of any of the foregoing, (ii) to a Competing Hospital Provider, (iii) to others providing outpatient medical services (“Outpatient Medical Services”) offered by Kaleida within the Medical Campus (“Competing Outpatient Services”, as defined below).

By way of example only, it shall not be considered a significant ancillary use if a physician or medical provider is drawing blood from his/her patients incidental to his/her practice or, if, in the regular course of practice, a physician or medical provider provides limited diagnostic testing through the use of such portable diagnostic tools as a portable sonogram.

The prohibition against Tenant subleasing space within the Premises to Competing Medical Providers, to Competing Hospital Providers, or to others providing Competing Outpatient Services, as set forth in (i) through (iii) above shall terminate if Kaleida does not own or operate a major hospital facility within the Medical Campus, as shall the restrictions set forth below.

procedure which may be performed on an outpatient basis, is a diagnostic test or treatment, including certain surgical procedures, that carries a low patient risk, requires minimal pre- and post-procedure observation and treatment, is not likely to be time consuming or followed by complications, and is not associated with a condition which would require hospitalization.

Provided Kaleida owns, controls or operates a full service hospital facility at the Medical Campus, Tenant shall not sell the Tenant’s Improvements or assign its rights pursuant to this Lease to a Competing Medical Provider, a Competing Hospital Provider, or to a party providing Competing Outpatient Services.

Each of the Subleases into which Tenant enters at the Premises will contain the following language: “Tenant agrees that it will not engage in any uses of the premises except as expressly set forth herein, without the prior written consent of Landlord and Prime Landlord, which consent may be withheld or denied in accordance with the Terms of the Prime Lease. Tenant further agrees that Prime Landlord is an intended third party beneficiary of the provisions of this Lease defining and restricting the uses permitted hereunder. Accordingly, Prime Landlord will have all rights and remedies available at law or in equity to enforce such provisions directly against Tenant or anyone claiming by or through Tenant”.
