If client is exempt from federal, state, sales, and use taxes the client will not be charged the same upon providing EdTech with sufficient evidence of said exemption.

10. Confidential Information.

(a). Definitions. For purposes of this section, a Party receiving Confidential Information (as defined below) shall be the “Recipient” and the Party disclosing such information shall be the “Discloser” and “Confidential Information” means all information disclosed by Discloser to Recipient during the Term and marked as “confidential” or “proprietary”. Client hereby acknowledges that the Services (including any Documentation, Software, and any translations, compilations, partial copies and derivative works thereof) will be considered Confidential Information belonging exclusively to EdTech (or its designated third party supplier), and EdTech hereby acknowledges that Client Data will be considered Confidential Information belonging to Client, in each case regardless of whether or not marked as “confidential” or “proprietary”.

(b). Covenant. To the extent permitted by law, recipient hereby agrees that during the Term and at all times thereafter it shall not (i) disclose such Confidential Information of the Discloser to any person or entity, except to its own personnel having a “need to know” (and who themselves are bound by similar nondisclosure restrictions), and to such other recipients as the Discloser may approve in writing; provided that all such recipients shall have first executed a confidentiality agreement in a form acceptable to Discloser; (ii) use Confidential Information of the Discloser except to exercise its license rights or perform its obligations under this Agreement; or (iii) alter or remove from any Confidential Information of the Discloser any proprietary legend. Recipient shall use at least the same degree of care in safeguarding the Confidential Information of the Discloser as it uses in safeguarding its own confidential information of a similar nature, but in no event shall less than due diligence and reasonable care be exercised. Upon the earlier of Discloser’s written request or termination or expiration of this Agreement, and regardless of whether a dispute may exist, Recipient shall return or destroy (as instructed by Discloser) all Confidential Information of Discloser in its possession or control and cease all further use thereof. Notwithstanding the foregoing, Recipient may disclose Discloser’s Confidential Information to the extent that such disclosure is necessary for the Recipient to enforce its rights under this Agreement or is required by law or by the order of a court or similar judicial or administrative body, provided that the Recipient promptly notifies the Discloser in writing of such required disclosure and cooperates with the Discloser to seek an appropriate protective order.

(c). Injunctive Relief. Recipient acknowledges that violation of the provisions of this section would cause irreparable harm to Discloser not adequately compensable by monetary damages. In addition to other relief, it is agreed that injunctive relief shall be available without necessity of posting bond to prevent any actual or threatened violation of such provisions.

CLIENT AGREES THAT THE USE OF SOFTWARE AND SERVICES IS AT CLIENT’S OWN RISK. NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY EDTECH OR AN EDTECH REPRESENTATIVE SHALL CREATE A WARRANTY OR IN ANY WAY INCREASE THE SCOPE OF ANY WARRANTY. SOME JURISDICTIONS MAY NOT ALLOW THE EXCLUSION OF CERTAIN IMPLIED WARRANTIES, SO THE ABOVE EXCLUSION MAY NOT FULLY APPLY TO CLIENT.

(b). Limited Non-Infringement Warranty. EdTech warrants that it has the right to license to Client the Software and Services as contemplated by this Agreement. EdTech represents and warrants that as of the date the Software and Services is first made available hereunder, when properly used in accordance with the Documentation and this Agreement, will not misappropriate or infringe any third party’s intellectual property rights recognized under any trade secret law, any U.S. copyright, or U.S. patent issued as of the Effective Date.

(c). Limited Privacy Warranty. EdTech hereby recognizes that the Client Data which Client provides to EdTech may include personal information of students. In order for EdTech to carry out its obligations under this Agreement, it is necessary for EdTech to use the Client Data. EdTech agrees to use the Client Data, some of which may contain personal information of students, only for the purpose of fulfilling its obligations under this Agreement. EdTech agrees all usage of Client Data shall be in compliance with the requirements of applicable privacy laws. EdTech warrants that it has put in place reasonable and appropriate security, technical and organizational measures to protect its usage of the Client Data against accidental or unlawful destruction or accidental loss, alterations, and unauthorized use, disclosure or access.

12. Limitation of Liabilities.

The Parties acknowledge that the following provisions have been negotiated by them and reflect a fair allocation of risk and form an essential basis of the bargain and shall survive and continue in full force and effect despite any failure of consideration or of an exclusive remedy:

EDTECH SHALL NOT BE LIABLE TO CLIENT FOR ANY SPECIAL, EXEMPLARY, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES; OR LOST PROFITS, LOST FUNDING, LOST SAVINGS, OR LOST OR DAMAGED DATA; OR FOR CLAIMS OF A THIRD PARTY; ARISING OUT OF THIS AGREEMENT, SOFTWARE, THIRD PARTY SOFTWARE, SUPPORT, HOSTING, SERVICES, OR OTHER ITEMS PROVIDED, OR THE USE OR INABILITY TO USE ANY OF THE FOREGOING, EVEN IF EDTECH HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE. IN ANY EVENT, IN RESPECT OF ANY CLAIM, DEMAND OR ACTION ARISING OUT OF THIS AGREEMENT, CLIENT SHALL BE LIMITED TO RECEIVING ACTUAL AND DIRECT DAMAGES IN A MAXIMUM AGGREGATE AMOUNT EQUAL TO THE CHARGES PAID BY CLIENT TO EDTECH HEREUNDER FOR THE APPLICABLE LICENSED PRODUCT, ITEM OR SERVICE ON WHICH THE CLAIM IS BASED IN THE PREVIOUS TWELVE (12) MONTHS.

13. Notices.

Notices sent to either Party shall be effective when delivered electronically or physically to the address designated by Client and in the case of EdTech to the attention of: EdTech Contracts and in the case of Client to the recipient provided by Client at the commencement of the Services and/or use of Software. Notices must be in writing. Each Party may change its address for receipt of notice by giving notice of such change to the other Party.

In addition, either party shall have the right to terminate this Agreement in whole or in part upon thirty (30) days written notice to the other party, in the event the other party materially breaches this Agreement and fails to correct such breach within such thirty (30) day period; provided that EdTech shall have the right to terminate this Agreement immediately upon written notice in the event that Client breaches any of its obligations under Section 10. Client further acknowledges that, as breach of the provisions of Section 10 could result in irreparable injury to EdTech, EdTech shall have the right to seek equitable relief against any actual or threatened breach thereof, without proving actual damages.

(b). Liquidated Damages. In the event that Client enters into a multi-year contract with EdTech and Client terminates the contract or any portion thereof, Client agrees to pay EdTech the remaining sum due to EdTech through the stated term of the Proposal/SOW as liquidated damages, as actual damages being impossible to calculate. This clause shall not apply in the event Client terminates this Agreement as a result of EdTech’s breach in accordance with Subsection 15(a) herein. Notwithstanding the foregoing, Client shall not be liable for said liquidated damages in the event that: (i) Client provides EdTech at least thirty (30) days’ advance notice of termination prior to the effective date anniversary; and (ii) said termination is a result of the non-appropriation of funds for Client’s contract. Client shall not utilize this clause as a right to terminate the contract for convenience. EdTech reserves the right to seek documentation evidencing the non- appropriation of funds.

(c). Survival. Upon termination or expiration of this Agreement for any reason: (i) all rights and obligations of both Parties (except for Client’s payment of all Fees then owing), including all licenses granted hereunder, shall immediately terminate except as provided below; (ii) within thirty (30) days after the effective date of termination, each Party shall comply with the obligations to return or destroy, at EdTech’s sole discretion, all Confidential Information of the other Party, as set forth in Section 10 (“Confidential Information”).

(g). Waiver. Waiver of any provision hereof in one instance shall not preclude enforcement thereof on future occasions.

(h). Counterparts; Facsimile Signature. EdTech requires Client’s execution of select purchase orders and/or SOWs, all of which are incorporated into this Agreement, and may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. If any purchase order and/or SOW is executed in counterparts, no signatory hereto shall be bound until both the Parties named below have duly executed or caused to be duly executed a counterpart of said purchase order and/or SOW. A signature received by either Party by facsimile is binding upon (the other Party) as an original.
