All required insurance (including insurance required pursuant to Article 5) shall be primary, issued by companies with an A.M. Best rating of A-VII or better and contain a provision whereby it cannot be canceled unless the carriers endeavor to provide Landlord with at least thirty (30) days’ prior written notice of the cancellation.

Tenant shall not do or permit to be done any act which shall invalidate or be in conflict with Landlord’s insurance policies, or increase the rates of insurance applicable to the Building. If, solely as the result of a Default, the insurance rates for the Building increase, in addition to any other obligation or liability of Tenant or any right or remedy of Landlord, Tenant shall reimburse Landlord for the increased premiums, within fifteen (15) days following Tenant’s receipt of Landlord’s written request.

Section 13.4 Landlord and Tenant shall, to the extent obtainable, each procure a clause in, or endorsement on, any property insurance carried by it, pursuant to which the insurance company waives its right of subrogation against the other party to this Lease and its agents and employees or consents to a waiver of the right of recovery against the other party to this Lease and its agents and employees. If an additional premium is required for the waiver or consent, the other party shall be advised of that amount and may, but is not obligated to, pay the same. If that party elects not to pay the additional premium, the waiver or consent shall not be required in

favor of that party. Provided its right of full recovery under its insurance policy is not adversely affected, Landlord and Tenant each hereby releases the other (and its agents and employees) with respect to any claim (including a claim for negligence) it may have against the other for damage or loss covered by its property insurance (including business interruption and loss of rent).

Subject to the provisions of this Article 14, Landlord shall, at Landlord’s expense, repair the damage, excluding the damage to Tenant’s Work or Tenant’s Property, to the extent of the insurance proceeds received or which would have been received had Landlord maintained the insurance required by the terms of this Lease, in a manner which is in all material respects reasonably comparable to the status of the Premises prior to the occurrence of such damage; and (b) Tenant shall, at Tenant’s expense, promptly remove Tenant’s Property from the Premises to the extent reasonably required by Landlord in connection with Landlord’s repair of the damage.

If Landlord and Tenant do not elect to terminate this Lease pursuant to this Section 14.2, Landlord shall proceed to repair or rebuild the Premises with due diligence and the provisions of Section 14.1 hereof shall apply. For purposes of this Section 14.2, the Premises shall be deemed to be “materially damaged” if the cost of repairing any such damage exceeds 25% of the replacement cost thereof or the damage impacts 25% or more of the aggregate square footage of the Premises and in each case cannot be repaired or rebuilt with reasonable diligence within six (6) months of the date of the occurrence of such damage or destruction, in each case as reasonably determined by an independent and reputable architect or engineer selected by Landlord.

Section 14.3 For greater certainty, the parties confirm that in the event this Lease is terminated due to fire or other casualty under this Article 14, no Early Termination Fee is payable to Tenant, and the Escrow Agent shall, in such circumstances, be instructed to release and remit the Early Termination Fee funds to Landlord.

Section 15.2 Each party shall have the right to claim and recover from the expropriating Authorities such compensation as may be separately awarded or recoverable. Landlord and Tenant agree to inform each other fully as to their respective claims for compensation made by them in the event of any expropriation and not to claim compensation on any basis inconsistent with this Lease and to reasonably cooperate with each other in the prosecution of any proper separate claims. Neither party shall compromise the claim of the other party without its prior written consent.

Section 15.3 If a taking does not result in the termination of this Lease (a) Landlord shall, at Landlord’s expense, as soon as practicable, subject to receipt of compensation award from the expropriating authority, restore that part of the Premises, the Building or the Land not taken, so that the Premises are usable which restoration shall, as necessary, include providing alternative means of ingress, egress, and other common areas, and (b) from and after the date Tenant is required by Law to vacate by reason of such taking, the Rent shall be reduced in the same proportion as the area of the Premises, if any, which was taken.

Section 15.4 For greater certainty, the parties confirm that in the event this Lease is terminated due to expropriation or condemnation under this Article 15, no Early Termination Fee is payable to Tenant, and the Escrow Agent shall, in such circumstances, be instructed to release and remit the Early Termination Fee funds to Landlord.

with all current applicable Environmental Laws. If an issue of non-compliance is found, Landlord shall take such action as is necessary to bring such condition into compliance at Landlord’s expense unless such non-compliance is due to the activities of Tenant (or those for whom Tenant is in law responsible).

Section 16.4 Tenant hereby indemnifies Landlord and each and every of its officers, directors, employees, agents and shareholders and agrees to hold each of them harmless from and against any and all Liabilities, including any Order, arising (directly or indirectly) out of or relating to any Hazardous Materials contamination in, under or on the Premises which at any time or from time to time may be paid, incurred or asserted against any of them for, with respect to or as a direct or indirect result of, the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission or release from, the Premises of any Hazardous Materials, but only to the extent caused by the act, omission or negligence of Tenant or anyone for whom it is in law responsible. For greater certainty, Tenant shall have no liability for any Hazardous Materials located in, on, under or upon the Building or any part thereof prior to the Commencement Date, or which migrate to or under the Building from adjacent properties after the Commencement Date.

The transfer, redemption or issuance (by one or more transactions) of ownership interests of Tenant or any direct or indirect parent of Tenant that is a controlled Affiliate of Ciena Corporation or its successor which results in 50 percent or more of the ownership interests of that person being held by persons other than Ciena Corporation, its successor or their controlled Affiliates (“Change of Control”) shall be considered an assignment of this Lease which requires Landlord’s consent, unless such ownership interests are publicly traded on a national stock exchange or over the counter market. For the avoidance of doubt, a change in control of Ciena Corporation shall not be deemed a Change of Control nor require Landlord’s consent. Landlord’s consent to an assignment, subletting or occupancy shall not relieve Tenant from any liability under this Lease or from obtaining Landlord’s consent to any further assignment, subletting or occupancy.

Section 17.2 Intentionally Deleted.

Section 17.3 In the event that Tenant wishes to engage in an assignment of the Lease or a sublet of the Premises which requires Landlord’s consent in accordance with this Article 17, it shall give Landlord notice of Tenant’s desire, accompanied by (i) an executed copy of the proposed assignment (with an assumption agreement signed by the assignee in a form acceptable to landlord, acting reasonably, (ii) a reasonably detailed description of the proposed assignee or subtenant and its principals, the nature of its business and its proposed use of the Premises, and (iii) current financial information with respect to the proposed assignee or subtenant, including its most recent financial statements (and Tenant shall promptly deliver to Landlord such additional information as Landlord reasonably requests).

Section 17.4 Any permitted assignee or subtenant, including as permitted by Section 17.7, shall perform and observe all of Tenant’s covenants contained in this Lease, including providing the same guaranty, if any, as provided by Tenant. Tenant shall be responsible for any act or omission of any assignee or subtenant (or anyone claiming through any assignee or subtenant) which violates this Lease, and that violation shall be considered a violation by Tenant.

Section 17.5 If Landlord, provided it has acted in accordance with its rights under Section 17.1, denies consent to a proposed assignment or sublease, Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s managing agent, if any, against and from any and all loss, liability, damages, costs and expenses (including reasonable counsel fees) resulting from any claims that may be made against Landlord or Landlord’s managing agent, if any, by any proposed assignee or subtenant or by any brokers or other person claiming a commission or similar compensation in connection with the proposed assignment or sublease.

Section 17.6 Tenant shall pay Landlord, within fifteen (15) days following payment to Tenant, (a) all sums and other consideration in connection with an assignment, after Tenant recovers therefrom all reasonable costs incurred by Tenant in connection with that assignment which have been paid or are then due and payable; and (b) the excess, if any, of the rents, additional charges or other consideration in connection with a sublease over the Rent allocable to the subleased premises (which Rent shall be allocated equally throughout the Premises) accruing during the term of that sublease after Tenant recovers therefrom all reasonable costs incurred by Tenant in connection with that sublease which have been paid or are then due and payable. This Section shall not apply to an assignment or a sublease described in Section 17.7.

Section 17.7 Tenant may, without Landlord’s consent,

(a) assign this Lease or sublet all or any part of the Premises to any person which, directly or indirectly, controls, is controlled by, or is under common control with Tenant (which means the ownership, directly or indirectly, of more than 50 percent of all voting ownership interests or the possession, directly or indirectly, of the power to direct management), or permit any such person to occupy all or any part of the Premises in each case in connection with the any Permitted Use of the Premises;

(b) assign this Lease to a purchaser of all or substantially all of the assets of Tenant, or

(c) sublet to any person or persons up to [*] of the Rentable Area of the Premises in the aggregate, provided that Landlord shall be entitled to [*] of the rents, additional charges or other consideration in connection with a sublease over the Rent allocable to the subleased premises (which Rent shall be allocated equally throughout the Premises) accruing during the term of that sublease after Tenant recovers therefrom all reasonable costs incurred by Tenant in connection with that sublease which have been paid or are then due and payable;

and provided further that (a) there is then no Default which is then subsisting, (b) Landlord is given not less than fifteen (15) days prior notice of the assignment, sublet or occupancy, including an executed original of all related documents, including an original assignment (with an assumption signed by the assignee), sublease or permission, and proof reasonably satisfactory to Landlord of the requisite control, and (c) the assignee or subtenant assumes in writing all the obligations hereunder. No such assignment, subletting or occupancy shall relieve Tenant from any liability under this Lease or from obtaining Landlord’s consent to any further assignment, subletting or occupancy.

Article 18. Access

Section 18.1 Landlord shall have the right, without the same constituting an eviction or constructive eviction of Tenant in whole or in part and without any abatement of the Rent or liability to Tenant, to (a) place (and have access to) concealed ducts, pipes and conduits through the Premises (without a material reduction or reconfiguration of the useable area of the Premises), (b) access to the Premises where necessary for Landlord to carry out its obligations under this Lease at such times mutually agreeable with Tenant and accompanied by a representative of Tenant, on at least 48 hours prior notice (except in the case of an emergency or to avoid damage to persons or property, in which case Landlord shall use reasonable efforts to contact the representative designated by Tenant as its liaison for addressing emergencies on Tenant’s behalf prior to accessing the Premises), (c) maintain or repair the Building (including the Building Systems) or the Carling Campus; (d) change the name, number or designation by which the Building is known; and (e) take all material into the Premises that may be required in connection with any of the matters described in this Section. If in an emergency or to avoid damage to persons or property, Tenant is not present when Landlord desires to enter the Premises and Landlord is unable to reach a Tenant representative, Landlord or Landlord’s contractors may enter the Premises, by force, without liability to Tenant.

Section 18.2 If there is to be any excavation or construction adjacent to the Building, Tenant shall permit Landlord or any agent of Landlord to enter the Premises on reasonable prior written notice to perform such work as Landlord or that person deems necessary to protect the Building, without any abatement of the Rent or liability to Tenant.

Section 18.3 Except as may be provided in this Lease, all walls, windows and doors bounding the Premises (including exterior walls of the Building, core corridor walls, and exterior doors and entrances, other than surfaces facing the interior of the Premises and doors and entrances servicing only the Premises), balconies, terraces, vaults, Building systems and all other


[*]		Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

portions of the Building are reserved to Landlord for Landlord’s use, are not part of the Premises, and Landlord may have access thereto through the Premises.

Section 18.4 Landlord acknowledges that any information delivered or received by Landlord from Tenant or otherwise in accordance with the undertaking of its duties or the exercise of its rights herein in respect of the business conducted by Tenant at the Premises shall remain confidential and proprietary to Tenant, and Landlord agrees to hold and keep such information confidential as and to the full extent provided herein. For greater certainty, “confidential information” refers to, without limitation, all financial, technical, all analyses, inventories, correspondence, reports, studies or other material when prepared by Tenant or its representatives. Landlord shall use reasonable efforts to exercise Landlord’s rights to access the Premises under this Lease, including this Section 18, in a manner which respects Tenant’s security requirements and provides Tenant with at least 48 hours prior written notice of the exercise of such rights and which minimizes interference with the conduct of Tenant’s business in the Premises and damage to the Premises, Tenant’s Work and Tenant’s Property (all of which shall promptly be repaired by Landlord, at its expense).

Section 18.5 Except in the case of emergency or to avoid damage to persons or property, Tenant shall be entitled to require that Landlord and any of its agents and employees be accompanied by representatives of Tenant when accessing the Premises. Notwithstanding anything in this Article to the contrary, Landlord shall use commercially reasonable efforts to minimize any interference and disruption to Tenant’s business caused by the exercise of its rights under this Article 18.

Article 19.Default

Section 19.1 Each of the following is a “Default” by Tenant under this Lease:

(a) Tenant fails to pay when due any Rent and the failure continues for ten (10) days following Landlord’s written notice (which notice shall also be considered any demand required by any Law). If, however, Landlord gives such a written notice twice in any consecutive 12-month period, any additional failure to pay any Rent when due within that 12-month period shall be considered an immediate Default (without the requirement of any notice by Landlord);

(b) Tenant fails to comply with Article 17;

(c) Tenant fails to comply with any other teen of this Lease and the failure continues for thirty (30) days following Landlord’s notice. If, however, compliance cannot, with diligence, reasonably be fully accomplished within that 30-day period, Tenant shall have an additional 30-day period to comply, provided Tenant promptly commences compliance and thereafter pursues compliance to completion with all due diligence;

(d) Tenant institutes, or has instituted against it any legal action seeking any relief from its debts under any Law which is not dismissed within sixty (60) days; a receiver, trustee, custodian or other similar official is appointed for it or for all or a substantial portion of its assets; Tenant becomes insolvent or is unable to pay its debts or fails or admits in writing its

inability generally to pay its debts as they become due; or Tenant commits any other act indicating insolvency;

(e) Tenant commits an act of default under the Additional Premises Lease which subsists beyond any applicable cure period provided for therein;

(f) Tenant fails to comply with requirements of Section 21.1 to ensure the Security continues to represent three (3) month’s Rent throughout the Term.

Section 19.2 If a Default occurs, Landlord may at any time during the continuance of the Default give notice to Tenant that this Lease shall terminate on the date specified in that notice, which date shall not be less than five (5) days after Landlord’s notice to Tenant. If Landlord gives that notice, the Term shall expire on the date set forth in that notice (but Tenant shall remain liable as provided in this Lease).

Section 19.3 If Tenant is in arrears in the payment of the Rent, Tenant waives Tenant’s right, if any, to designate the items against which any payments made by Tenant are to be credited, and Landlord may apply any payments made by Tenant to any items Landlord sees fit.

Article 20. Remedies

Section 20.1 If this Lease is terminated pursuant to Article 19 or Landlord re-enters or obtains possession of the Premises by summary proceedings or any other legal action (which Landlord may do without further notice and without liability or obligation to Tenant or any occupant of the Premises), all of the provisions of this Section shall apply (in addition to any other applicable provisions of this Lease).

(a) Tenant (and all other occupants) shall vacate and surrender to Landlord the Premises in accordance with this Lease.

(b) Landlord, at Landlord’s option, may (i) re-let the Premises, or any portion of the Premises, from time to time, in the name of Landlord, Tenant or otherwise, as determined by Landlord, to any person and on any terms, but Landlord shall have no obligation to re-let the Premises, or any portion of the Premises, or to collect any rent (and the failure to re-let the Premises, or any portion of the Premises, or to collect any rent shall not impose any liability or obligation on Landlord or relieve Tenant of any obligation or liability under this Lease), and (ii) make any changes to the Premises as Landlord, in Landlord’s judgment, considers advisable or necessary in connection with a re-letting, without imposing any liability or obligation on Landlord or relieving Tenant of any obligation or liability under this Lease.

(c) Tenant shall pay Landlord all Rent payable to the date on which this Lease is terminated or Landlord re-enters or obtains possession of the Premises.

(d) Tenant shall also pay to Landlord, as damages, any deficiency between (i) the aggregate Rent for the period which otherwise would have constituted the unexpired portion of the Term to the Fixed Expiration Date (including any increases in additional rent for each year thereof in accordance herewith) and any expenses incurred by Landlord in connection with the termination, reentry or obtaining of possession, and the re-letting of the Premises, including all

repossession costs, brokerage commissions, reasonable attorneys’ fees and disbursements, alteration costs and other expenses of preparing the Premises for re-letting and (ii) the Rent, if any, applicable to that period collected under any re-letting of any portion of the Premises. Tenant shall pay any deficiency in monthly installments on the days specified in this Lease for payment of installments of the Fixed Rent, and Landlord shall be entitled to recover from Tenant each monthly deficiency as the same arises. No suit to collect the deficiency for any month shall prejudice Landlord’s right to collect the deficiency for any subsequent month. Tenant shall not be entitled to any rents payable (whether or not collected) under any re-letting, whether or not those rents exceed the Rent.

(e) Landlord may recover from Tenant, and Tenant shall pay Landlord, on request, in lieu of any further deficiency pursuant to paragraph (d) of this Section (as liquidated damages) the amount by which (i) the unpaid Rent for the period which otherwise would have constituted the unexpired portion of the Term (including any increases in additional rent for each year thereof in accordance herewith) exceeds (ii) the then fair and reasonable rental value of the Premises, including the additional rent for the same period, both discounted to present value at the annual rate of interest (the “Base Rate”) publicly announced by the Royal Bank of Canada (or any successor thereto) as its “base rate” on the date of the Default in question, or such other term as may be used by the Royal Bank of Canada from time to time for that rate (and if no longer publicly announced, then a similar rate selected by Landlord). If, before presentation of proof of liquidated damages, Landlord re-lets the Premises or any portion of the Premises for any period pursuant to a bona fide lease with an unrelated third party, the net rents payable in connection with the re-letting shall be considered to be the fair and reasonable rental value for the Premises or the portion of the Premises re-let during the term of the re-letting. If Landlord re-lets the Premises, or any portion of the Premises, together with other space in the Building, the rents collected under the re-letting and the expenses of the re-letting shall be equitably apportioned for the purposes of this Article.

(f) Nothing contained in this Lease shall be considered to limit or preclude the recovery by Landlord from Tenant of the maximum amount allowed to be obtained as damages or otherwise by any Law.

Section 20.2 Tenant hereby waives (a) the service of any notice of intention to re-enter or obtain possession of the Premises or to institute any legal action in connection therewith, except as provided in this Lease and (b) on its own behalf and on behalf of all persons claiming under Tenant, including all creditors, any rights Tenant and all such persons might otherwise have under any Law to redeem the Premises, to re-enter or repossess the Premises, or to restore this Lease, after (i) Tenant is dispossessed pursuant to any Law or by any Authority, (ii) Landlord reenters or obtains possession of the Premises pursuant to any legal action, or (iii) the Expiration Date, whether by operation of law or pursuant to this Lease (including the occurrence of the Expiration Date by Landlord terminating this Lease pursuant to Section 19.2). The words “re-enter,” “re-entry” and “re-entered” as used in this Lease shall not be considered to be restricted to their technical legal meanings. Landlord shall have the right to enjoin any Default and the right to invoke any remedy allowed by any Law in addition to any remedies provided in this Lease. All remedies provided in this Lease are cumulative and Landlord’s right to invoke, or invocation of, any remedy shall not preclude Landlord from invoking any other remedy.

Section 20.3 For greater certainty, the parties confirm that in the event this Lease is terminated due to a Default by the Tenant under this Lease, no Early Termination Fee is payable to Tenant, and the Escrow Agent shall, in such circumstances, be instructed to release and remit the Early Termination Fee funds to Landlord.

Section 20.4 If there is a Default, or if Tenant fails to comply with any obligation under this Lease which, in Landlord’s reasonable opinion creates an emergency or danger to the health or safety of any person or risk of damage to property, Landlord may, but is not obligated to, cure the Default or, without notice, cure the failure to comply, for the account of Tenant. All amounts incurred by Landlord in that connection, and any amounts (including reasonable attorneys’ fees and disbursements) in instituting, prosecuting or defending any legal action by or against Tenant, or in connection with any dispute under this Lease, in which Landlord prevails, with interest thereon at the Default Rate, shall be paid by Tenant to Landlord within fifteen (15) days following Tenant’s receipt of Landlord’s request. Landlord shall promptly reimburse Tenant for any reasonable legal fees and disbursements incurred by Tenant in connection with any legal action or other dispute with Landlord under this Lease, in which Tenant prevails.

Section 20.5 The failure of Landlord to seek redress for a Default, or of Landlord or Tenant to insist upon the strict performance of any term of this Lease, shall not prevent Landlord from redressing a subsequent Default or Landlord or Tenant from thereafter insisting on strict performance. The receipt by Landlord of the Rent with knowledge of a Default or Tenant’s failure to strictly perform under this Lease shall not be deemed a waiver of the Default or failure. No term of this Lease shall be considered waived by Landlord or Tenant unless the waiver is in a writing signed by the waiving party. No payment by Tenant or receipt by Landlord of a lesser amount than the Rent shall be considered other than on account of the next installment of the Rent, or as Landlord may elect to apply same. No endorsement or statement on any check or letter accompanying any check or payment shall prevent Landlord from cashing the check or otherwise accepting the payment, without prejudice to Landlord’s right to recover the balance of the Rent or pursue any other remedy.

Section 20.6 If Tenant fails to pay any installment of the Fixed Rent on the first day of the month or any Additional Rent when due, in addition to any other right or remedy of Landlord, Tenant shall pay to Landlord within fifteen (15) days following Landlord’s written notice interest at the rate (the “Default Rate”) which is the lesser of the rate of 5% per annum above the Base Rate or the maximum legal interest rate permitted under the circumstances, on the amount unpaid, from the date the payment was first due to and including the date paid.

Article 21. Security

Section 21.1 Tenant has deposited with Landlord, as security for Tenant’s compliance with this Lease, the Security by a standby letter of credit on the terms, and substantially in the form, attached to this Lease as Exhibit “D”, issued by a bank listed under Schedule I, Schedule II or Schedule III of the Bank Act (Canada) (the “Letter of Credit”). If there is a Default, Landlord may use all or any portion of the Security, only as necessary, to cure the Default or for the payment of any other amount due and payable from Tenant to Landlord in accordance with this Lease. Tenant shall, within thirty (30) days following Landlord’s written notice, deposit with Landlord in cash or by a Letter of Credit an amount sufficient to restore the full amount of

the Security (without giving consideration to any interest accrued on the Security) following a Default. Landlord may assign the Security to a permitted assignee of this Lease, or to a Mortgagee of the Carling Campus. Landlord shall not be required to exhaust its remedies against Tenant or the Security before having recourse to Tenant, the Security or any other security held by Landlord, or before exercising any right or remedy, and recourse by Landlord to any one of them, or the exercise of any right or remedy, shall not affect Landlord’s right to pursue any other right or remedy or Landlord’s right to proceed against the others. If there is then no uncured Default, the Security and any accrued and unpaid interest thereon, or any balance, shall be paid or delivered to Tenant promptly after the Expiration Date and Tenant’s vacating of the Premises in accordance with this Lease. If Landlord’s interest in the Building is sold or leased, Landlord shall transfer the Security and any accrued and unpaid interest thereon, or any balance, to the new landlord and, upon such transfer and delivery of an agreement in writing in favor of Tenant wherein the assignee assumes all obligations of Landlord under this Lease whenever arising (including in respect of the Security), the assignor shall thereupon be released by Tenant from all liability for the return of the Security or any interest (and Tenant agrees to look solely to the assignee for the return of the Security or any interest).

Section 21.2 Given Tenant has elected to post the Security by way of a Letter of Credit, the following provisions of this Section shall also apply (in addition to the other provisions of this Article):

(a) If the bank issuing the Letter of Credit shall notify Landlord that the term of the Letter of Credit shall not be renewed, Tenant shall, at least thirty (30) days prior to the expiration date of the Letter of Credit, replace the Letter of Credit with a new Letter of Credit, having an initial expiration date at least one year from the date of the new Letter of Credit. If Tenant fails to so renew and does not otherwise provide cash by the date that is fifteen (15) days prior to expiry, Landlord may draw on the Letter of Credit and hold the cash and all interest earned thereon as Security hereunder.

(b) If, for any reason other than Landlord’s failure to comply with the requirements of the Letter of Credit, the bank issuing the Letter of Credit shall fail or refuse to honor any demand, Tenant shall within fifteen (15) days following Landlord’s written notice to Tenant of such failure or refusal, at Landlord’s option, either (i) deposit with Landlord the Security in cash or (ii) replace the Letter of Credit with a new Letter of Credit (having an initial expiration date at least one year from the date of the new Letter of Credit).

(c) If Landlord shall transfer its interest in the Building, Tenant shall, at the request of the transferor or transferee, replace or amend the Letter of Credit within fifteen (15) days following such request, so that the transferee is named as the beneficiary. Any reasonable transfer fee or charge imposed by the bank issuing the Letter of Credit shall be reimbursed to Landlord (or, at Landlord’s option, paid) by Tenant within fifteen (15) days following Landlord’s request.

(d) If there shall be a Default, in addition to any other right or remedy of Landlord, Landlord shall have the right, to immediately draw the full amount of the Letter of Credit and then hold the cash and all interest thereon as Security hereunder and apply such amounts in accordance with the provisions of Section 21.1 hereof.

Article 22. Broker

Section 22.1 Except for fees and commissions that will be paid by Tenant to CB Xxxxxxx Xxxxx for which Tenant hereby indemnifies Landlord, no broker is entitled to any fee or commission in connection with the transactions contemplated by this Lease based upon arrangements made by or on behalf of Tenant or any of its affiliates. Except for fees and commissions that will be paid by Landlord for which Landlord hereby indemnifies Tenant, no broker is entitled to any fee or commission in connection with the transactions contemplated by this Lease based upon arrangements made by or on behalf of Landlord or any of its affiliates.

Article 23. Notices

Section 23.1 Except as may be expressly provided in this Lease, all notices and other communications under this Lease must be in writing and sent by nationally recognized overnight courier service or registered or certified mail (return receipt requested), addressed to Landlord or Tenant at its Notice Address.

Section 23.2 Any notice or other communication sent as provided in this Article shall be effective (a) on the date received (or rejected) if sent overnight courier service, or (b) two Business Days after mailing by registered or certified mail.

Section 23.3 Any notice or other communication given by Landlord to Tenant in accordance with this Article may be signed and given by Landlord’s managing agent, if any, with the same force and effect as if signed and given by Landlord.

Article 24. Representations and Liability

Section 24.1 Neither Landlord nor any of Landlord’s agents, employees or representatives has made any warranties, representations, statements or promises with respect to the Premises, the Building, the Land, the Building systems, any additional rent, any Law or any other matter, unless expressly set forth in this Lease. This Lease, Escrow Agreement and the ASA contain the entire agreement between Landlord and Tenant with respect to the subject matter of this Lease, and any previous agreements between Landlord and Tenant are merged in this Lease, which alone expresses their agreement. Tenant is entering into this Lease after full investigation, and is not relying on any warranties, representations, statements or promises made by Landlord or any other person not expressly set forth in this Lease or in the ASA, and is not acquiring any rights of any nature, by implication or otherwise, except as expressly set forth in this Lease.

Section 24.2 No act or omission of Landlord or Tenant, or their respective employees, agents or contractors, including the delivery or acceptance of keys, shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid unless it is in a writing signed by Landlord. Any employee of Landlord, Landlord’s managing agent, if any, or the Building to whom any property is entrusted by or on behalf of Tenant shall be deemed to be acting as Tenant’s agent with respect to that property and neither Landlord nor Landlord’s managing agent, if any, shall be liable for any damages to or loss of property of Tenant or others entrusted to employees, agents or contractors of Landlord, Landlord’s managing agent, if any, or the Building.

Section 24.3 Neither Landlord nor Landlord’s managing agent, if any, shall be liable for any injury, damage or loss to Tenant, Tenant’s Property, Tenant’s Work, Tenant’s business or to any other person or property resulting from any cause, except to the extent caused by the negligence act or omission of Landlord, Landlord’s managing agent, if any, or their respective employees, agents or contractors, subject to Section 13.4.

Section 24.4 If, at any time or from time to time, any windows of the Premises are temporarily closed, blocked or darkened for any reason, or permanently closed, blocked or darkened if required by any Law or due to any construction on property adjacent to the Building by any person, including Landlord or any person in which Landlord has an interest (a) Landlord shall not be liable for any loss or damage Tenant may sustain thereby, (b) Tenant shall not be entitled to any compensation or abatement of the Rent, (c) Tenant shall not be relieved of its obligations under this Lease and (d) it shall not constitute an eviction or constructive eviction of Tenant from the Premises.

Section 24.5 Subject to the provisions of Section 27.1, in the event of a transfer of the Building (a) the Landlord shall be and hereby is relieved of all obligations and liabilities of Landlord under this Lease accruing after the effective date of the assumption by the transferee; and (b) the transferee shall be deemed to have assumed all of Landlord’s obligations and liabilities under this Lease effective from and after the effective date of the transfer.

Section 24.6 Landlord, its partners, members, shareholders, officers, directors and principals, disclosed or undisclosed, have no personal liability under or in connection with this lease. Tenant shall look only to Landlord’s interest in the Premises and the Carling Campus for the satisfaction of Tenant’s remedies or to collect any judgment requiring the payment of money by Landlord under or in connection with this lease, and no other assets of Landlord or such persons shall be subject to lien, levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies or the collection of any judgment under or in connection with this lease. If Tenant acquires a lien on such other property or assets by judgment or otherwise, Tenant shall promptly release that lien by signing, acknowledging and delivering to Landlord any instrument, prepared by Landlord, required for the lien to be released.

Section 24.7 Intentionally deleted

Section 24.8 It is understood and agreed that whenever and to the extent that Landlord or Tenant shall be unable to fulfill or shall be delayed or restricted in the fulfillment of any obligation hereunder in respect of the supply or provision of any service or utility or the doing of any work or the making of any repairs by reason of delays caused by acts of God, war, civil riot, insurrection, strike or labour dispute not caused by the party claiming same, unusual delays in transportation of materials, unusual government delays, or delays due to condemnation, fire or other unavoidable casualty, being unable to obtain the material, goods or equipment required to enable it to fulfill such obligation (collectively and individually, “Unavoidable Delay”) then, provided the party claiming a benefit of a delay due to Unavoidable Delay shall have the obligations to: (i) notify the other party within a reasonable time period after such delay commences; and (ii) use its best efforts to minimize the duration of such delay and the effect of the delay, Landlord or Tenant (as the case may be) shall be relieved from the fulfillment of such obligation during the period of such delay and the other party shall not be entitled to

compensation for any inconvenience, nuisance or discomfort thereby occasioned, provided that in no event will Tenant be relieved of its obligation to pay Rent. Notwithstanding the foregoing, the inability to procure funds shall not be considered to be or to result in an event of Unavoidable Delay.

Section 24.9 Tenant shall not perform or permit to be performed any act which may subject Landlord or Landlord’s managing agent, if any, to any liability. Tenant shall, to the extent not caused by the negligence or willful misconduct of Landlord or its contractors or agents, indemnify, defend and hold harmless Landlord and Landlord’s managing agent, if any, from and against (a) all claims arising from any act or omission of Tenant, its contractors, agents, employees, invites or visitors, (b) all claims arising from any accident, injury or damage to any person or property in the Premises during the Term or when Tenant is in possession of the Premises, and (c) Tenant’s failure to comply with Tenant’s obligations under this Lease (whether or not a Default), and all liabilities, damages, losses, fines, costs and expenses (including reasonable attorneys’ fees and disbursements) incurred in connection with any such claim or failure.

Article 25. End of Term

Section 25.1 On the Expiration Date (a) Tenant (and all other occupants) shall vacate and surrender the Premises, broom clean, in good order and condition, and with interior finished including but not limited to carpets and other floor finishes, window coverings, ceilings and paint in substantially the same condition as at the Commencement Date, except for ordinary wear and tear and damage by fire and other casualty for which Tenant is not responsible under this Lease, and otherwise as may be required by this Lease, including if required by Landlord, removal of Tenant’s Work and Tenant’s Property. Tenant shall be under no obligation to return the Premises to base building standard. For greater certainty, Landlord acknowledges and agrees that Tenant shall not be obligated or responsible, under any circumstance, for the removal or restoration of any installations, alterations, partitions or improvements of any kind whatsoever existing in, on or under the Premises as of the Commencement Date, other than to repair any damage caused by the removal of Tenant’s Work and Tenant’s Property. If the last day of the Term is not a Business Day, this Lease shall expire on the immediately preceding Business Day. Should Tenant fail to yield up space in accordance with its obligations, Landlord may carry out works on behalf of Tenant and recover any costs incurred in doing so. Tenant waives, for itself and for any person claiming under Tenant, any right which Tenant or any such person may have to a stay of proceedings.

Section 25.2 If the Premises are not vacated and surrendered in accordance with this Lease, on the date required by this Lease, Tenant shall be liable to Landlord for (a) all losses, costs, liabilities and damages which Landlord incurs by reason thereof, including reasonable attorneys’ fees, and (b) per diem use and occupancy in respect of the Premises equal to 150% of the then current Rent payable under this Lease (which Landlord and Tenant presently agree is the Rent to which Landlord would be entitled, is presently contemplated by them as being fair and reasonable under such circumstances and is not a penalty) until Tenant vacates and surrenders the Premises in accordance with this Lease. Tenant shall indemnify, defend and hold harmless Landlord against all claims made by any succeeding tenants against Landlord or otherwise resulting from the failure of Tenant (and all other occupants) timely to vacate and surrender the

Premises in accordance with this Lease. In no event, however, shall this Section be construed as permitting Tenant (and all other occupants) to remain in possession of the Premises after the Expiration Date. Landlord and Tenant agree that any statutory right to hold over after the expiration of the term is expressly waived in accordance with applicable Laws.

Section 25.3 Any obligation of Landlord or Tenant under this Lease which by its nature or under the circumstances can only be, or by the terms of this Lease may be, performed after the Expiration Date and any liability for a payment with respect to any period ending on or before the Expiration Date, unless otherwise set forth in this Lease, shall survive the Expiration Date.

Article 26. Tenant’s Self-Help Remedy

Section 26.1 While the Landlord is Nortel Networks Technology Corporation, or any entity affiliated with Nortel Networks Technology Corporation or Nortel Networks Limited, and except in the case of an Unavoidable Delay, if Landlord shall default in the performance or observance of any obligation or condition in this Lease on its part to be performed or observed which results in a Material Interruption (as hereinafter defined) and shall not cure such default within two (2) Business Days after notice from Tenant specifying the default (or shall not within such period have commenced to cure the default and be pursuing the cure of the default with due diligence), Tenant may, at its option, without waiving any claim for damages for the default permitted under this Lease, at any time thereafter, and on written notice to Landlord, take such steps as are necessary to cure such default. Tenant shall submit detailed invoices to Landlord for the costs incurred by Tenant to cure such default of Landlord, and if Landlord fails to pay the costs so invoiced, or to provide notice to Tenant denying that it has committed a default or responsibility for the costs so invoiced (which notice must include reasonable detail of the grounds on which Landlord is supporting such assertion) and request an arbitration of the issue pursuant to Section 26.2 within fifteen (15) days after its receipt of the aforesaid invoice, Tenant shall have the right to deduct such costs, and interest thereon, from the amounts then owed for any Rent due or to become due by Tenant to Landlord under this Lease until the invoice amounts are satisfied in full (“Set-off Right”). Tenant’s right to cure a default of Landlord under this Section 26.1 shall not preclude it from pursuing any other rights available to it under this Lease or at law in the event that the Set-off Right is insufficient to compensate Tenant for its costs and expenses resulting from Landlord’s default under this Section 26.1 (it being agreed that in no event shall Landlord be responsible for indirect, consequential damages or losses of intangible property). For purposes of this Section 26.1, “Material Interruption” means any circumstance, other than an Unavoidable Delay, a casualty under Article 14 or an Expropriation or Condemnation under Article 15, caused by a default by Landlord which would prevent or impede Tenant’s access to or ability to conduct business from the Premises in a material manner (such as, loss or interruption of utilities or failure of any critical Building System).

Landlord grants to Tenant a non-exclusive right on, over, within and across the Common Areas for purposes of exercising the self-help remedy hereinbefore provided.

Section 26.2 If Landlord denies that it has committed a default or disputes responsibility for the costs claimed by Tenant pursuant to Section 26.1, then Landlord shall, within fifteen (15) days after receipt of an invoice from Tenant in respect of the claim under Section 26.1, request that the matter be resolved as follows:

(a)

However, before or during the time that the Disputing Party and the Receiving Party follow the procedures specified in this Section 26.2 above, either party may make application to the appropriate court for a preliminary injunction or other preliminary judicial relief if such party reasonably believes that such a step is necessary to avoid irreparable damage or harm, Even if either party takes such action, both parties will continue to participate in good faith in the procedures specified in this Section 26.2 above.

Section 26.3 Subject to the provisions of Section 26.4, if the Premises are sold to any person not affiliated with Landlord or Norte] Networks Limited (“New Landlord”) and the

(a) At the time of the sale of the Campus, a sum of money equivalent to [*] shall be deposited into an interest bearing escrow account of the Escrow Agent by Landlord or the New Landlord to represent the full extent of security for the performance of the New Landlord’s obligations under this Lease (“Landlord Security Account”);

(b) Except in the case of an Unavoidable Delay, if the New Landlord shall default in the performance or observance of any obligation or condition in this Lease on its part to be performed or observed which results in a Material Interruption and shall not cure such default within two (2) Business Days after Notice from Tenant specifying the default (or shall not within such period commence to cure the default and thereafter be pursuing the cure of the default with due diligence), Tenant may, at its option, without waiving any claim for damages for the default permitted under this Lease, at any time thereafter, and on written notice to the New Landlord, take such steps as are necessary to cure such default. Tenant shall submit detailed invoices to the New Landlord for the costs incurred by Tenant to cure such default of the New Landlord, and if the New Landlord fails to pay the costs so invoiced, or to provide notice to Tenant denying that it has committed a default or responsibility for the costs so invoiced (which notice must include reasonable detail of the grounds on which Landlord is supporting such assertion) and request an arbitration of the issue in accordance with the provisions of Section 26.2 within fifteen (15) days after its receipt of the aforesaid invoices, Tenant shall have the right to unilaterally instruct and direct the Escrow Agent to pay Tenant the costs so invoiced from the Landlord Security Account.

Article 27. Early Termination by Landlord

Section 27.1 Effective at any time after the end of the thirtieth (30th) month of the Term (the “Standstill Period”), Landlord will have the right to early terminate the Term of this Lease at any time on at least thirty (30) months prior written notice (the “Early Termination Notice” and the “Early Termination Notice Period”) to Tenant in the event that the Carling Campus is sold to a bona fide arm’s length purchaser who requires vacant possession of the Premises occupied by Tenant prior to the end of the Term (the “Early Termination Right”).


[*]		Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

For greater clarity, the Landlord’s entitlement to provide the Early Termination Notice shall be at any time during the Term, provided that it is effective only as and from the end of the Standstill Period, and the Early Termination Notice Period shall commence on the date Tenant has received both the Early Termination Notice and the Early Termination Fee. The Early Termination Right is personal to, and may only be exercised by, Nortel Networks Technology Corporation or any of its Affiliates during the period of its or their ownership of the Premises.

Section 27.2 If Landlord exercises the Early Termination Right, it will direct the Escrow Agent to pay to Tenant from the Carling Property Escrow Amount the Early Termination Fee within three (3) Business Days of the delivery of the Early Termination Notice.

Section 27.3 The termination fee payable pursuant to Section 27.2 shall be USD $33,500,000 (plus applicable taxes and all interest earned thereon, the “Early Termination Fee”). For the period commencing on the seventy-third (73^rd) month of the Term, the Early Termination Fee shall begin to be reduced on a monthly schedule at a rate of USD$697,916.67, such monthly reductions to be effective on the expiry of each month such that on the expiry of the Term, the Early Termination Fee would be $0.

For greater clarity, the table set out in Exhibit “E” hereto sets forth the Early Termination Fee which would be payable in the event the Lease was terminated at the end of each of the listed months in accordance with this Article 27.

Section 27.4 Notwithstanding anything to the contrary herein, the provisions in respect of the Early Termination Fee and the payment by Landlord thereof to Tenant in this Article 27 shall apply, mutatis mutandis, in respect of any termination of the Lease resulting from an Incurable Termination Event. For purposes of this Article 27, “Incurable Termination Event” means any termination of this Lease prior to the expiry of the Term as a result of the occurrence of any circumstance under any Lien resulting in the subject lien claimant terminating the Lease or foreclosing Tenant’s leasehold interest under this Lease (including as a result of the failure to pay Taxes when due) resulting in Tenant being force to vacate the Premises as applicable, but provided that the such circumstance has not resulted due to the Default of Tenant under the terms of this Lease.

Section 27.5 In the event that Landlord provides written notice to Tenant irrevocably waiving the Early Termination Right and agreeing that Article 27 shall be of no further force or effect, and provided that at the time of the giving of such notice to Tenant no proceedings are being prosecuted by a lien claimant in respect of a Lien securing a material obligation which could result in this Lease being terminated, the Escrow Agent shall be instructed to release the Early Termination Fee to Landlord.
