Except for an assignment by the Share Acquiror of this Agreement or any rights hereunder to an Affiliate or Permitted Transferee (which assignment will not relieve the Share Acquiror of any obligation hereunder), neither this Agreement nor any of the rights or obligations hereunder may be assigned by either the Share Acquiror or the Company without (a) the prior written consent of Company in the case of any assignment by the Share Acquiror or (b) the prior written consent of the Share Acquiror in the case of an assignment by the Company.

11.12 Remedies. The rights, powers and remedies of the parties under this Agreement are cumulative and not exclusive of any other right, power or remedy which such parties may have under any other Contract or Law. No single or partial assertion or exercise of any right, power or remedy of a party hereunder shall preclude any other or further assertion or exercise thereof. The parties hereby acknowledge and agree that the rights of the parties hereunder are special, unique and of extraordinary character, and that if any party refuses or otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, such refusal or failure would result in irreparable injury to the Company or the Share Acquiror as the case may be, the exact amount of which would be difficult to ascertain or estimate and the remedies at law for which would not be reasonable or adequate compensation. Accordingly, if any 

party refuses or otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, then, in addition to any other remedy which may be available to any damaged party at law or in equity, such damaged party will be entitled to seek specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual or threatened damages, which remedy such damaged party will be entitled to seek in any court of competent jurisdiction.
11.13 Expenses. Each party shall pay its own fees and expenses in connection with the preparation, negotiation, execution, delivery and performance of the Transaction Agreements.

APPENDIX 1
REGISTRATION RIGHTS
1. Resale Registration.
1.1 On or prior to the first (1st) Business Day following the expiration of the Lockup Period, the Company will file a Shelf Registration Statement registering for resale the Registrable Securities under the Securities Act. The Company shall use its commercially reasonable efforts to cause such Shelf Registration Statement to become effective as promptly as practicable after filing. Until the earlier of such time as (i) all Registrable Securities cease to be Registrable Securities or (ii) the Company is no longer eligible to maintain a Shelf Registration Statement, the Company will keep current and effective such Shelf Registration Statement and file such supplements or amendments to such Shelf Registration Statement (or file a new Shelf Registration Statement when such preceding Shelf Registration Statement expires pursuant to the rules of the SEC) as may be necessary or appropriate in order to keep such Shelf Registration Statement continuously effective and useable for the resale of Registrable Securities under the Securities Act. The Shelf Registration Statement shall include the Plan of Distribution attached hereto as Annex A.
1.2 If the filing, initial effectiveness or continued use of the Shelf Registration Statement at any time would require the Company to make a public disclosure of material non-public information that the Company has a bona fide business purpose for not disclosing publicly at such time, the Company may, upon giving prompt written notice of such action to the Share Acquiror, delay the filing or initial effectiveness of, or suspend use of, the Shelf Registration Statement (a “Suspension”); provided, however, that the Company shall not be permitted to exercise a Suspension more than once during any twelve (12) month period for a period not to exceed sixty (60) days. In the case of a Suspension, the Share Acquiror agrees to suspend use of the applicable Prospectus in connection with any sale or purchase, or offer to sell or purchase, Shares, upon receipt of the notice referred to above. The Company shall immediately notify the Share Acquiror in writing upon the termination of any Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Share Acquiror such numbers of copies of the Prospectus as so amended or supplemented as the Share Acquiror may reasonably request. The Company shall, if necessary, supplement or amend the Shelf Registration Statement, if required by law or as may reasonably be requested by the Share Acquiror.
2. Information. The Company may require the Share Acquiror to furnish to the Company such information regarding the distribution of the Shares and such other information relating to the Share Acquiror and its ownership of Shares as the Company may from time to time reasonably request in writing to the extent that such information is required to be included in the Shelf Registration Statement.
3. Expenses. All expenses incident to the Company’s performance of or compliance with this Agreement shall be paid by the Company, including (a) all registration and filing fees, and any other fees and expenses associated with filings required to be made with the SEC or Financial Industry Regulatory 

Authority, (b) all fees and expenses in connection with compliance with any securities or “Blue Sky” laws (including reasonable fees and disbursements of counsel for the Underwriters in connection with blue sky qualifications of the Shares), (c) all printing, duplicating, word processing, messenger, telephone and delivery expenses (including expenses of printing certificates for the Shares in a form eligible for deposit with The Depository Trust Company and of printing Prospectuses), (d) all fees and disbursements of counsel for the Company and of all independent certified public accountants or independent auditors of the Company and any of its Subsidiaries (including the expenses of any special audit and comfort letters required by or incident to such performance), (e) Securities Act liability insurance or similar insurance if the Company so desires, (f) all fees and expenses incurred in connection with the listing of the Shares on any securities exchange or quotation of the Shares on any inter-dealer quotation system, (g) all fees and expenses of any special experts or other Persons retained by the Company in connection with any registration, and (h) all of the Company’s internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties). For the avoidance of doubt, the Company shall not be required to pay any underwriting discounts and commissions and transfer Taxes, if any, attributable to the sale of the Shares.
4. Notice. The Company shall notify the Share Acquiror immediately upon (a) any request by the SEC or any other Federal or state Governmental Authority for amendments or supplements to a Shelf Registration Statement or for additional information that pertains to the Share Acquiror as a selling stockholder; (b) the issuance by the SEC of any stop order suspending the effectiveness of the Shelf Registration Statement or any order by the SEC or any other regulatory authority preventing or suspending the use of any Prospectus or the initiation or threatening of any proceedings for such purposes, (c) receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for offering or sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, or (d) the Company becoming aware that the Shelf Registration Statement or the related Prospectus contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein (in the case of such Prospectus, in light of the circumstances under which they were made) not misleading. 
5. Indemnification.
5.1 To the extent permitted by Law, the Company will indemnify and hold harmless the Share Acquiror, its officers and directors, and each Person who controls the Share Acquiror (within the meaning of the Securities Act or the Exchange Act), and the officers and directors, of each such controlling Person, from and against any and all losses, claims, liabilities, damages, deficiencies, assessments, fines, judgments, fees, costs (including, without limitation, reasonable costs of preparation and reasonable attorneys’ fees) and expenses (collectively “Losses”) (joint or several), as incurred, to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such Losses (or actions in respect thereof) arise out of, relate to, or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (a) any untrue statement or alleged 

untrue statement of a material fact contained in the Shelf Registration Statement or incorporated by reference therein, including any Prospectus contained therein or any amendments or supplements thereto, (b) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (c) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities Law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities Law in connection with the Shelf Registration Statement; and the Company will reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or action if it is judicially determined that there was such a Share Acquiror Violation; provided however, that the indemnity agreement contained in this Section 5.1 will not apply to amounts paid in settlement of any such Loss or action if such settlement is effected without the Company’s consent, nor will the Company be liable in any such case for any such Loss to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished by the Share Acquiror and stated to be expressly for use in connection with the Shelf Registration Statement or an applicable Prospectus.
5.2 To the extent permitted by Law, the Share Acquiror will indemnify and hold harmless the Company and each of its directors and its officers against any Losses (joint or several) to which the Company or any such director, officer, controlling Person, Underwriter or other Third Party who may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such Losses (or actions in respect thereto) arise out of or are based upon any of the following statements: (a) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any other document incorporated reference therein, including any preliminary Prospectus or final Prospectus contained therein or any amendments or supplements thereto, or (b) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading (collectively, a “Share Acquiror Violation”), in each case to the extent (and only to the extent) that such Share Acquiror Violation occurs in reliance upon and in conformity with written information furnished by the Share Acquiror under an instrument duly executed by the Share Acquiror; and the Share Acquiror will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling Person, Underwriter or other Third Party in connection with investigating or defending any such Loss or action if it is judicially determined that there was such a Share Acquiror Violation; provided, however, that the indemnity agreement contained in this Section 5.2 will not apply to amounts paid in settlement of any such Loss or action if such settlement is effected without the Share Acquiror’s consent; provided, further that the obligations of the Share Acquiror hereunder shall be limited to an amount equal to the net proceeds it receives in such Registration.
5.3 Promptly after receipt by an indemnified party under this Section 5 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 5, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party will have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other 

indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party will have the right to retain its own counsel, with the fees and expenses thereof to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action will relieve such indemnifying party of any liability to the indemnified party under this Section 5 to the extent, and only to the extent, prejudicial to its ability to defend such action, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 5.
5.4 If the indemnification provided for in this Section 5 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any Losses referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, will to the extent permitted by applicable Law contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other, in connection with the Violation(s) or Share Acquiror Violation(s), as applicable, that resulted in such Loss, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party will be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that the obligations of the Share Acquiror hereunder shall be limited to an amount equal to the net proceeds it receives in such Registration; and provided, further, that no Person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.
5.5 The obligations of the Company and the Share Acquiror under this Section 5 will survive termination of this Agreement and the expiration or withdrawal of the Shelf Registration Statement. No indemnifying party, in the defense of any such claim or litigation, will, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

ANNEX A
PLAN OF DISTRIBUTION
The selling securityholders, including their pledgees, donees, transferees, distributees, beneficiaries or other successors in interest, may from time to time offer some or all of the shares of common stock (collectively, “Securities”) covered by this prospectus. To the extent required, this prospectus may be amended and supplemented from time to time to describe a specific plan of distribution. 
The selling securityholders will not pay any of the costs, expenses and fees in connection with the registration and sale of the Securities covered by this prospectus, but they will pay any and all underwriting discounts, selling commissions and stock transfer taxes, if any, attributable to sales of the Securities. We will not receive any proceeds from the sale of Securities. 
The selling securityholders may sell the Securities covered by this prospectus from time to time, and may also decide not to sell all or any of the Securities that they are allowed to sell under this prospectus. The selling securityholders will act independently of us in making decisions regarding the timing, manner and size of each sale. These dispositions may be at fixed prices, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale, or at privately negotiated prices. Sales may be made by the selling securityholders in one or more types of transactions, which may include: 

	
								
	 
	 
	 

	•
	purchases by underwriters, dealers and agents who may receive compensation in the form of underwriting discounts, concessions or commissions from the selling securityholders and/or the purchasers of the Securities for whom they may act as agent;
	 

	 
	 
	 
	 
	 

	•
	one or more block transactions, including transactions in which the broker or dealer so engaged will attempt to sell the Securities as agent but may position and resell a portion of the block as principal to facilitate the transaction, or in crosses, in which the same broker acts as an agent on both sides of the trade;
	 
	 
	 

	 
	 
	 
	 
	 
	 

	•
	ordinary brokerage transactions or transactions in which a broker solicits purchases;
	 
	 
	 
	 

	 
	 
	 
	 
	 
	 
	 

	•
	purchases by a broker-dealer or market maker, as principal, and resale by the broker-dealer for its account;
	 
	 
	 
	 
	 

	 
	 
	 
	 
	 
	 

	•
	the pledge of Securities for any loan or obligation, including pledges to brokers or dealers who may from time to time effect distributions of Securities, and, in the case of any collateral call or default on such loan or obligation, pledges or sales of Securities by such pledgees or secured parties;
	 
	 
	 
	 

	 
	 
	 
	 
	 
	 

	•
	short sales or transactions to cover short sales relating to the Securities;
	 
	 
	 
	 

	 
	 
	 
	 
	 

	•
	one or more exchanges or over the counter market transactions;
	 
	 
	 

	 
	 
	 
	 

	•
	through distribution by a selling securityholder or its successor in interest to its members, general or limited partners or shareholders (or their respective members, general or limited partners or shareholders);
	 
	 

	 
	 
	 
	 
	 
	 
	 
	 

	•
	privately negotiated transactions;
	 
	 
	 
	 
	 
	 

	 
	 
	 
	 
	 
	 
	 

	•
	the writing of options, whether the options are listed on an options exchange or otherwise;
	 
	 
	 
	 
	 

	 
	 

	•
	distributions to creditors and equity holders of the selling securityholders; and

	 
	 
	 
	 
	 
	 

	•
	any combination of the foregoing, or any other available means allowable under applicable law.
	 
	 
	 
	 

A selling securityholder may also resell all or a portion of its Securities in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”) provided it meets the criteria and conforms to the requirements of Rule 144 under the Securities Act and all applicable laws and regulations.
The selling securityholders may enter into sale, forward sale and derivative transactions with third parties, or may sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with those sale, forward sale or derivative transactions, the third parties may sell securities covered by this prospectus, including in short sale transactions and by issuing securities that are not covered by this prospectus but are exchangeable for or represent beneficial interests in the common 

stock. The third parties also may use shares of common stock received under those sale, forward sale or derivative arrangements or shares of common stock pledged by the selling securityholder or borrowed from the selling securityholders or others to settle such third-party sales or to close out any related open borrowings of common stock. The third parties may deliver this prospectus in connection with any such transactions. Any third party in such sale transactions will be an underwriter and will be identified in a supplement or a post-effective amendment to the registration statement of which this prospectus is a part, as may be required. 
In addition, the selling securityholders may engage in hedging transactions with broker-dealers in connection with distributions of Securities or otherwise. In those transactions, broker-dealers may engage in short sales of securities in the course of hedging the positions they assume with selling securityholders. The selling securityholders may also sell securities short and redeliver securities to close out such short positions. The selling securityholders may also enter into option or other transactions with broker-dealers which require the delivery of securities to the broker-dealer. The broker-dealer may then resell or otherwise transfer such securities pursuant to this prospectus. The selling securityholders also may loan or pledge Securities, and the borrower or pledgee may sell or otherwise transfer the Securities so loaned or pledged pursuant to this prospectus. Such borrower or pledgee also may transfer those Securities to investors in our securities or the selling securityholders’ securities or in connection with the offering of other securities not covered by this prospectus. 
To the extent necessary, the specific terms of the offering of Securities, including the specific Securities to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any underwriter, broker-dealer or agent, if any, and any applicable compensation in the form of discounts, concessions or commissions paid to underwriters or agents or paid or allowed to dealers will be set forth in a supplement to this prospectus or a post-effective amendment to this registration statement of which this prospectus forms a part. The selling securityholders may, or may authorize underwriters, dealers and agents to, solicit offers from specified institutions to purchase Securities from the selling securityholders. These sales may be made under “delayed delivery contracts” or other purchase contracts that provide for payment and delivery on a specified future date. If necessary, any such contracts will be described and be subject to the conditions set forth in a supplement to this prospectus or a post-effective amendment to this registration statement of which this prospectus forms a part. 
Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from the selling securityholders. Broker-dealers or agents may also receive compensation from the purchasers of Securities for whom they act as agents or to whom they sell as principals, or both. Compensation to a particular broker-dealer might be in excess of customary commissions and will be in amounts to be negotiated in connection with transactions involving securities. In effecting sales, broker-dealers engaged by the selling securityholders may arrange for other broker-dealers to participate in the resales. 
In connection with sales of Securities covered hereby, the selling securityholders and any underwriter, broker-dealer or agent and any other participating broker-dealer that executes sales for the selling securityholders may be deemed to be an “underwriter” within the meaning of the Securities Act. 

Accordingly, any profits realized by the selling securityholders and any compensation earned by such underwriter, broker-dealer or agent may be deemed to be underwriting discounts and commissions. Selling securityholders who are “underwriters” under the Securities Act must deliver this prospectus in the manner required by the Securities Act. This prospectus delivery requirement may be satisfied in accordance with Rule 153 under the Securities Act or satisfied in accordance with Rule 174 under the Securities Act. 
We and the selling securityholders have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. In addition, we or the selling securityholders may agree to indemnify any underwriters, broker-dealers and agents against or contribute to any payments the underwriters, broker-dealers or agents may be required to make with respect to, civil liabilities, including liabilities under the Securities Act. Underwriters, broker-dealers and agents and their affiliates are permitted to be customers of, engage in transactions with, or perform services for us and our affiliates or the selling securityholders or their affiliates in the ordinary course of business. 
The selling securityholders will be subject to the applicable provisions of Regulation M of the Securities Exchange Act of 1934 and the rules and regulations thereunder, which provisions may limit the timing of purchases and sales of any of the Securities by the selling securityholders. Regulation M may also restrict the ability of any person engaged in the distribution of the Securities to engage in market-making activities with respect to the Securities. These restrictions may affect the marketability of such Securities. 
In order to comply with applicable securities laws of some states or countries, the Securities may only be sold in those jurisdictions through registered or licensed brokers or dealers and in compliance with applicable laws and regulations. In addition, in certain states or countries the Securities may not be sold unless they have been registered or qualified for sale in the applicable state or country or an exemption from the registration or qualification requirements is available. In addition, any Securities of a selling securityholder covered by this prospectus that qualify for sale pursuant to Rule 144 under the Securities Act may be sold in open market transactions under Rule 144 rather than pursuant to this prospectus. 
In connection with an offering of Securities under this prospectus, the underwriters may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress. 
The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased securities sold by or for the account of that underwriter in stabilizing or short-covering transactions. 
These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Securities offered under this prospectus. As a result, the price of the Securities may be higher than the 

price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected on the Nasdaq Global Select Market or another securities exchange or automated quotation system, or in the over-the-counter market or otherwise.

EXHIBIT B

TENANT FINISH-WORK: ALLOWANCE
(Landlord Performs the First Expansion Premises Work)

1.Acceptance of First Expansion Premises. Tenant accepts the First Expansion Premises in their “AS-IS” condition on the date that this First Amendment is entered into. Tenant intends to immediately accept Landlord’s delivery of the First Expansion Premises and conduct business therein, and intends to vacate the First Expansion Premises on or around the date on which Landlord delivers the Current Premises to Tenant with the Work in the Current Premises Substantially Completed, pursuant to the terms of the Existing Lease. Landlord and Tenant acknowledge and agree that on or prior to the First Expansion Premises Vacation Date (as defined below), Tenant shall vacate the First Expansion Premises and remove all personnel and all furniture, fixtures and equipment installed by Tenant, all at Tenant’s sole cost and expense, unless otherwise agreed to by Landlord in writing. Within 15 business days after the Work in the Current Premises is Substantially Completed, Landlord and Tenant will agree on a date by which Tenant shall vacate the First Expansion Premises (the “First Expansion Premises Vacation Date”); provided however, that if Landlord and Tenant fail agree on the First Expansion Premises Vacation Date within such 15 business day period, then the First Expansion Premises Vacation Date shall be the date that is 10 business days after the date on which the working drawings are fully approved (or deemed approved) by both Landlord and Tenant, as contemplated in Section 3.2 of this Exhibit. Tenant acknowledges and agrees that Landlord is not obligated to commence any First Expansion Premises Work, as contemplated by this Exhibit, unless and until Tenant vacates the First Expansion Premises pursuant to the terms of this Section 1.

		
	2.
	Space Plans.

2.1    Preparation and Delivery. On or before the tenth day following date on which Landlord delivers the Current Premises to Tenant with the Work in the Current Premises Substantially Completed, pursuant to the terms of the Existing Lease (the “First Amendment Space Plans Delivery Deadline”), Tenant shall deliver to Landlord a space plan prepared by a design consultant reasonably acceptable to Landlord (the “Architect”) depicting improvements to be installed in the First Expansion Premises (the “First Expansion Premises Space Plans”).

2.2    Approval Process. Landlord shall notify Tenant whether it approves of the submitted First Expansion Premises Space Plans within five business days after Tenant’s submission thereof. If Landlord disapproves of such First Expansion Premises Space Plans, then Landlord shall  notify Tenant thereof specifying in reasonable detail the reasons for such disapproval, in which case Tenant shall, within five business days after such notice, revise such First Expansion Premises Space Plans in accordance with Landlord’s objections and submit to Landlord for its review and approval. Landlord shall notify Tenant in writing whether it approves of the resubmitted First Expansion Premises Space Plans within three business days after its receipt thereof. This process shall be repeated until the First Expansion Premises Space Plans have been finally approved by Landlord and Tenant. If Landlord fails to notify Tenant that it disapproves of the initial First Expansion Premises Space Plans within five business days (or, in the case of resubmitted First Expansion Premises Space Plans, within three business days) after the submission thereof, then Landlord shall be deemed to have approved the First Expansion Premises Space Plans in question. If Tenant fails to timely deliver such First Expansion Premises Space Plans, then each day after the First Amendment Space Plans Delivery Deadline that such First Expansion Premises Space Plans are not delivered to Landlord shall be a Tenant Delay Day (defined below).

		
	3.
	First Expansion Premises Working Drawings.

3.1    Preparation and Delivery. On or before the date which is 15 days following the final approval of the First Expansion Premises Space Plans, as outlined in Section 2 above, Landlord shall cause to be prepared final working drawings of all improvements to be installed in the First Expansion Premises and deliver the same to Tenant for its review and approval (which approval shall not be unreasonably withheld, delayed or conditioned). Such working drawings shall be prepared by Architect

or another design consultant selected by Landlord. Unless otherwise expressly included in the approved First Expansion Premises Space Plans to the contrary, the First Expansion Premises Work shall be performed utilizing Building-standard materials and other materials that are readily available.

3.2    Approval Process. Tenant shall notify Landlord in writing whether it approves of the submitted working drawings within five business days after Landlord’s submission thereof. If Tenant disapproves of such working drawings, then Tenant shall notify Landlord thereof specifying in reasonable detail the reasons for such disapproval, in which case Landlord shall, within five business days after such notice, revise such working drawings in accordance with Tenant’s objections and submit the revised working drawings to Tenant for its review and approval. Tenant shall notify Landlord in writing whether it approves of the resubmitted working drawings within three business days after its receipt thereof. This process shall be repeated until the working drawings have been finally approved by Landlord and Tenant. If Tenant fails to notify Landlord that it disapproves of the initial working drawings within five business days (or, in the case of resubmitted working drawings, within three business days) after the submission thereof, then Tenant shall be deemed to have approved the working drawings in question. Any delay caused by Tenant’s unreasonable withholding of its consent or delay in giving its written approval as to such working drawings shall constitute a Tenant Delay Day. If the working drawings are not  fully approved (or deemed approved) by both Landlord and Tenant by the 15th business day after the delivery of the initial draft thereof to Tenant, then each day after such time period that such working drawings are not fully approved (or deemed approved) by both Landlord and Tenant shall constitute a Tenant Delay Day.

3.3     Landlord’s Approval; Performance of First Expansion Premises Work. If  any of Tenant’s proposed construction work will affect the Building’s Structure or the Building’s Systems, then the working drawings pertaining thereto must be approved by the Project’s engineer of record. Landlord’s approval of such working drawings shall not be unreasonably withheld, provided that (a) they comply with all Laws, (b) the improvements depicted thereon do not (1) adversely affect (in the reasonable discretion of Landlord) the Building’s Structure or the Building’s Systems (including the Project’s restrooms or mechanical rooms), or (2) affect (in the sole discretion of Landlord) (A) the exterior appearance of the Project, (B) the appearance of the Project’s common areas or elevator lobby areas, or
(C) the provision of services to other occupants of the Project, (c) such working drawings are sufficiently detailed to allow construction of the improvements and associated work in a good and workmanlike manner for the entire First Expansion Premises, and (d) the improvements depicted thereon conform to the rules and regulations promulgated from time to time by Landlord for the construction of tenant improvements (a copy of which has been delivered to Tenant). As used herein, “First Expansion Premises Working Drawings” means the final working drawings approved by Landlord, as amended from time to time by any approved changes thereto, and “First Expansion Premises Work” means all improvements to be constructed by Landlord in accordance with and as indicated on the First Expansion Premises Working Drawings, together with any work required by governmental authorities to be made to other areas of the Project as a result of the improvements indicated by the First Expansion Premises Working Drawings. The First Expansion Premises Work shall include the installation of an appropriate conduit for the containment of fiber optic cables, such that Tenant can install fiber optic cables (i) between the Current Premises and Suite 100 MDF/Server Room, and (ii) between the First Expansion Premises and the Suite 300 IDF closet, and Landlord hereby grants Tenant reasonable access to such areas of the Project as required in order to complete such installation, provided that any such installations shall constitute Tenant’s Off-Premises Equipment, as applicable. Landlord’s approval of the First Expansion Premises Working Drawings shall not be a representation or warranty of Landlord that such drawings are adequate for any use or comply with any Law, but shall merely be the consent of Landlord thereto.  Tenant shall, at Landlord’s request, sign the First Expansion Premises Working Drawings to evidence its review and approval thereof. After the First Expansion Premises Working Drawings have been approved, Landlord shall cause the First Expansion Premises Work to be performed in substantial accordance with the First Expansion Premises Working Drawings, using contractors and subcontractors selected by Landlord.

4.Bidding of First Expansion Premises Work. Tenant has the right to elect to use the same general contractor as was selected for the Work in the Current Premises by providing written notice

of such election to Landlord. If Tenant does not elect to use such contractor, then, prior to commencing the First Expansion Premises Work, Landlord shall competitively bid the First Expansion Premises Work to two contractors selected by Landlord and one contractor selected by the Tenant, and reasonably approved by Landlord. If the estimated First Expansion Premises Construction Costs are expected to exceed the First Expansion Premises Construction Allowance, Tenant shall be allowed to review the submitted bids from such contractors to value engineer any of Tenant’s requested alterations. In such case, Tenant shall notify Landlord of any items in the First Expansion Premises Working Drawings that Tenant desires to change within five business days after Landlord’s submission thereof to Tenant. If Tenant fails to notify Landlord of its election within such five business day period, Tenant shall be deemed to have approved the bids. Within seven business days following Landlord’s submission of the initial construction bids to Tenant under the foregoing provisions (if applicable), Tenant shall have completed all of the following items: (a) finalized with Landlord’s representative and the proposed contractor, the  pricing of any requested revisions to the bids for the First Expansion Premises Work, and (b) approved in writing any overage in the First Expansion Premises Construction Costs in excess of the First Expansion Premises Construction Allowance, failing which each day after such seven business day period shall constitute a Tenant Delay Day. Tenant and Landlord acknowledge and agree that Tenant shall select the contractor for the First Expansion Premises Work based on the bids, provided however that Tenant’s decision shall be subject to Landlord’s reasonable approval of such contractor’s bid.

5.Change Orders. Tenant may initiate changes in the First Expansion Premises Work. Each such change must receive the prior written approval of Landlord, such approval shall be granted or withheld in accordance with the standards set forth in Section 3.3 above; additionally, if any such requested change 

might (a) delay the First Expansion Premises Commencement Date or (b) leave any portion of the First Expansion Premises not fully finished and ready for occupancy, Landlord may  withhold its consent in its sole and absolute discretion. Landlord shall, upon completion of the First Expansion Premises Work, cause to be prepared accurate architectural, mechanical, electrical and plumbing “as-built” plans of the First Expansion Premises Work as constructed in both blueprint and electronic CADD format, which plan shall be incorporated into this 0 by this reference for all purposes. If Tenant requests any changes to the First Expansion Premises Work described in the First Expansion Premises Space Plans or the First Expansion Premises Working Drawings, then such increased costs and any additional design costs incurred in connection therewith as the result of any such change shall be added to the First Expansion Premises Construction Costs.

6.Definitions. As used herein, a “Tenant Delay Day” means each day of delay in the performance of the First Expansion Premises Work that occurs (a) because Tenant fails to timely furnish any information or deliver or approve any required documents such as the First Expansion Premises Space Plans or First Expansion Premises Working Drawings (whether preliminary, interim revisions or final), pricing estimates, construction bids, and the like, (b) because of any change by Tenant to the Space Plans or First Expansion Premises Working Drawings, (c) because Tenant fails to attend any meeting with Landlord, the Architect, any design professional, or any contractor, or their respective employees or representatives, as may be required or scheduled hereunder or otherwise necessary in connection with the preparation or completion of any construction documents, such as the First Expansion Premises Space Plans or First Expansion Premises Working Drawings, or in connection with the performance of the First Expansion Premises Work, (d) because of any specification by Tenant of materials or installations in addition to or other than Landlord’s standard finish-out materials or any materials that are not readily available, or (e) because a Tenant Party otherwise delays completion of the First Expansion Premises Work. As used herein “Substantial Completion,” “Substantially Completed,” and any derivations thereof mean the First Expansion Premises Work in the First Expansion Premises is substantially completed (as reasonably determined by Landlord, including, if applicable, Landlord’s  receipt of a Letter of Completion or other similar approval from the City of Boulder) in substantial accordance with the First Expansion Premises Working Drawings. Substantial Completion shall have occurred even though minor details of construction, decoration, landscaping and mechanical adjustments remain to be completed by Landlord.

7.Walk-Through; Punchlist. When Landlord considers the First Expansion Premises Work in the First Expansion Premises to be Substantially Completed, Landlord will notify Tenant and,

within three business days thereafter, Landlord’s representative and Tenant’s representative shall conduct a walk-through of the First Expansion Premises and identify any necessary touch-up work, repairs and minor completion items that are necessary for final completion of the First Expansion Premises Work. Neither Landlord’s representative nor Tenant’s representative shall unreasonably withhold his or her agreement on punchlist items. Landlord shall use reasonable efforts to cause the contractor performing the First Expansion Premises Work to complete all punchlist items within 30 days after agreement thereon; however, Landlord shall not be obligated to engage overtime labor in order to complete such items.

8.Excess Costs. Tenant shall pay the entire amount by which the First Expansion Premises Construction Costs (hereinafter defined) exceed the First Expansion Premises Construction Allowance (hereinafter defined) (such excess amount being referred to herein as the “Excess Amount”). Upon approval of the First Expansion Premises Working Drawings and selection of a contractor, Tenant shall promptly (a) execute a work order agreement prepared by Landlord which identifies such drawings and itemizes the First Expansion Premises Construction Costs and sets forth the First Expansion Premises Construction Allowance, and (b) pay to Landlord 50% of Landlord’s estimate of the Excess Amount. Within 30 days after Substantial Completion of the First Expansion Premises Work, Tenant shall pay to Landlord any remaining unpaid portion of the Excess Amount. In the event of default of payment  of any portion of the Excess Amount, Landlord (in addition to all other remedies) shall have the same rights as for an Event of Default under this Lease. As used herein, “First Expansion Premises Construction Costs” means the entire cost of performing the First Expansion Premises Work, including design of and space planning for the First Expansion Premises Work and preparation of the First Expansion Premises Working Drawings and the final “as-built” plan of the First Expansion Premises Work, costs of construction labor and materials, electrical usage during construction, additional janitorial services, standard building directory and suite tenant signage, related taxes and insurance costs, licenses, permits, certifications, surveys and other approvals required by Law, any applicable governmental fees, and the construction supervision fee referenced in Section 11 of this Exhibit.

9.First Expansion Premises Construction Allowance.  Landlord shall provide to Tenant a construction allowance not to exceed $60.00 per rentable square foot in the First Expansion Premises (the “First Expansion Premises Construction Allowance”) to be applied toward the First Expansion Premises Construction Costs, as adjusted for any changes to the First Expansion Premises Work. The First Expansion Premises Construction Allowance shall not be disbursed to Tenant in cash, but shall be applied by Landlord to the payment of the First Expansion Premises Construction Costs, if, as, and when the cost of the First Expansion Premises Work is actually incurred and paid by Landlord. The First Expansion Premises Construction Allowance must be used (that is, the First Expansion Premises Work must be fully complete and the First Expansion Premises Construction Allowance disbursed) within 18 months following the First Expansion Premises Commencement Date (the “Allowance Deadline”) or shall be deemed forfeited with no further obligation by Landlord with respect thereto, time being of the essence with respect thereto; provided, however, that if both parties are diligently pursuing completion of the First Expansion Premises Work, the Allowance Deadline will be extended by one day for each delay day caused by any force majeure event described in Section 25.3 of the Existing Lease. In no event shall any portion of the First Expansion Premises Construction Allowance be used towards the cost of the Work in the Existing Premises or towards the payment of Rent.

10.First Expansion Premises Space Plan Allowance. Landlord will provide up to $0.15 per rentable square foot of the First Expansion Premises (the “First Expansion Premises Space Plan Allowance”) to be applied towards the costs incurred for Architect's preparation of the Space Plans. Tenant shall be responsible for any space planning costs incurred in excess of the First Expansion Premises Space Plan Allowance. The First Expansion Premises Space Plan Allowance is in addition to the First Expansion Premises Construction Allowance. In no event shall any portion of the  First Expansion Premises Space Plan Allowance be used to fund any portion of the First Expansion Premises Construction Costs or to offset Tenant's Rent payments under the Lease. If the Architect is engaged by Landlord, and the cost of the space plan exceeds the First Expansion Premises Space Plan Allowance, such excess costs will be considered First Expansion Premises Construction Costs and payable by Tenant in accordance with Section 8 of this Exhibit. The First Expansion Premises Space Plan Allowance

shall not be disbursed to Tenant in cash, but shall be applied by Landlord to the payment of the First Expansion Premises Construction Costs, if, as, and when the cost of the First Expansion Premises Work is actually incurred and paid by Landlord. The First Expansion Premises Space Plan Allowance must be used (that is, the First Expansion Premises Work must be fully complete and the First Expansion Premises Space Plan Allowance disbursed) on or before the Allowance Deadline or shall be deemed forfeited with no further obligation by Landlord with respect thereto, time being of the essence with respect thereto; provided, however, that if both parties are diligently pursuing completion of the First Expansion Premises Work, the Allowance Deadline will be extended by one day for each delay day caused by any force majeure event described in Section 25.3 of the Existing Lease.

11.Construction Management. Landlord or its Affiliate or agent shall supervise the First Expansion Premises Work, make disbursements required to be made to the contractor, and act as a liaison between the contractor and Tenant and coordinate the relationship between the First Expansion Premises Work, the Project and the Building’s Systems. Landlord or its Affiliate or agent shall use commercially reasonable efforts to coordinate weekly telephonic or in-person status meetings with Tenant’s Representative. In consideration for Landlord’s construction supervision services, Tenant shall pay to Landlord a construction supervision fee equal to five percent of the First Expansion Premises Construction Costs (exclusive of the construction supervision fee).

12.Construction Representatives. Landlord’s and Tenant’s representatives for coordination of construction and approval of change orders will be as follows, provided that either party may change its representative upon written notice to the other:

EXHIBIT D RIGHT OF FIRST OFFER

Subject to then-existing renewal or expansion options or other preferential rights of other tenants, Landlord shall, prior to offering any suite on the third floor of the Building that is adjacent to the First Expansion Premises (the “Offer Space”) to any party (other than the then-current tenant or occupant therein), first offer to lease to Tenant the Offer Space in an “AS-IS” condition; such offer shall (a) be in writing, (b) specify the part of the Offer Space being offered to Tenant hereunder (the “Designated Offer Space”), and (c) specify the lease terms for the Designated Offer Space, including the rent to be paid for the Designated Offer Space and the date on which the Designated Offer Space shall be included in the Premises (the “Offer Notice”). The Offer Notice shall be substantially similar to the Offer Notice attached to this Exhibit. Tenant shall notify Landlord in writing whether Tenant elects to lease the entire  Designated Offer Space on the terms set forth in the Offer Notice, within three days after Landlord delivers to Tenant the Offer Notice. If Tenant timely elects to lease the Designated Offer Space, then Landlord and Tenant shall execute an amendment to this Lease, effective as of the date the Designated Offer Space is to be included in the Premises, on the terms set forth in the Offer Notice and, to the extent not inconsistent with the Offer Notice terms, the terms of this Lease; however, Tenant shall accept the Designated Offer Space in an “AS-IS” condition and Landlord shall not provide to Tenant any allowances (e.g., moving allowance, construction allowance, and the like) or other tenant inducements except as specifically provided in the Offer Notice. Notwithstanding anything in this Exhibit to the contrary, if prior to Landlord’s delivery to Tenant of the Offer Notice, Landlord has received a Third Party Offer to lease all or part of the Offer Space, and Landlord is willing to accept the terms of such Third Party Offer, and such Third Party Offer includes space in excess of the Offer Space, then Tenant must exercise its rights hereunder, if at all, as to all of the space contained in the Third Party Offer. To the extent that multiple tenants have rights to lease the Offer Space, Landlord may elect to deliver an Offer Notice to Tenant and such third party tenants at the same time, and if both Tenant and another third party tenant accept the Offer Notice, the party with the superior rights shall prevail.

If Tenant fails or is unable to timely exercise its right hereunder with respect to the Designated Offer Space, then such right shall lapse with respect to the Designated Offer Space, time being of the essence with respect to the exercise thereof (it being understood that Tenant’s right hereunder is a one- time right only as to each Designated Offer Space the first time it is offered to Tenant hereunder), and Landlord may lease all or a portion of the Designated Offer Space to third parties on such terms as Landlord may elect. For purposes hereof, if an Offer Notice provides for an expansion, right of first refusal, or other preferential right to lease some of the remaining portion of the Offer Space, then such remaining portion of the Offer Space shall thereafter be excluded from the provisions of this Exhibit. Unless otherwise agreed in writing by Landlord and Tenant’s real estate broker, in no event  shall Landlord be obligated to pay a commission with respect to any space leased by Tenant under this Exhibit, and Tenant and Landlord shall each indemnify the other against all costs, expenses, attorneys’ fees, and other liability for commissions or other compensation claimed by any broker or agent claiming the same by, through or under the indemnifying party.

Tenant’s rights under this Exhibit shall terminate, at Landlord’s option, if (a) an Event of Default exists as of the date of Tenant’s exercise of its rights under this Exhibit or as of the effective date of the addition of the Designated Offer Space to the Premises, (b) the Lease or Tenant’s right to possession of any of the Premises is terminated, (c) Tenant assigns its interest in the Lease or sublets any portion of  the Premises, (d) Tenant fails to lease from Landlord and occupy at least the same number of rentable square feet leased to Tenant as of the First Expansion Premises Commencement Date, (e) Landlord determines, in its sole but reasonable discretion, that Tenant’s financial condition or creditworthiness has materially deteriorated since the date of the First Amendment, (f) Tenant fails to timely exercise its option under this Exhibit, time being of the essence with respect to Tenant’s exercise thereof, or (g) less than two full calendar years remain in the initial Term of the Lease.

Tenant’s rights under this Exhibit shall not apply to leases that allow tenants in the Building to use such space as unfinished storage area and other temporary leases to provide temporary space to tenants

that ultimately will occupy other space in the Building on a permanent basis, any management space, tenant relocation space and other building space/amenities (conference center, fitness center, etc.).
