The information provided by Seller, and to Seller’s Knowledge by the Group and their respective advisers and consultants, to Purchaser or its advisers in connection with this Agreement and the evaluation and due diligence investigation conducted by Purchaser and Purchaser’s advisors is true and correct in all material respects, not misleading and presents a true and fair view of the business, assets and liabilities, financial position and earnings position of the Group. To Seller’s Knowledge, no information regarding any matters that are reasonably likely to have a material adverse affect on the Group and its business was withheld from Purchaser.

7.2 If and to the extent that Seller’s Guarantee is made to “Seller’s Knowledge”, Seller shall be deemed to have such knowledge if, as of the Signing Date, O’Connell Benjamin or William A. Marshall had actual knowledge (positive Kenntnis) or could have had actual knowledge without acting grossly negligent (grob fahrlässige Unkenntnis).

7.3 No Seller’s Guarantee shall be construed as a guarantee within the meaning of Sections 443 and 444 BGB.

8. REMEDIES, LIMITATIONS OF LIABILITY

8.1 In the event that any of Seller’s Guarantees has been breached (a “Breach”), Seller shall by way of remediation in kind (Naturalrestitution) put Purchaser, or at Purchaser’s election, the Group Companies in the same position they would be in if the Seller’s Guarantee had not been breached. Should (i) Seller fail to so remedy the Breach within 15 Business Days after a respective request of Purchaser or (ii) should remediation in kind not be possible due to the nature of the Breach or (iii) should remediation in kind by Seller be grossly inconsistent with legitimate significant business interests of Purchaser or the Group, Purchaser shall be entitled to request from Seller that it pay to Purchaser, or at Purchaser’s election, to the Group Companies, the amount of any Losses incurred or suffered by Purchaser and / or the Group Companies as a result of the Breach in cash (Schadensersatz in Geld), provided, however, that Purchaser may claim damages in cash (Schadensersatz in Geld) for a Breach of any of the Seller’s Guarantees in Section 7.1.8 (Tax Matters) only for 50% of the Losses, subject to the provisions of Sections 8.6 and 8.7(ii), below.

Share Purchase Agreement

8.2 “Losses” shall mean all losses, costs, expenses and other damages within the meaning of Sections 249 et seq. BGB, including in particular any lost profits (entgangener Gewinn) and any consequential damages (Folgeschäden), but excluding any reduction in value (Minderung) of the Group beyond the actual damage incurred, any losses to the Group’s goodwill, any reputational damage of the Group and any internal costs incurred by the Group or Purchaser. Section 254 BGB shall apply.

8.3 In the event of any Breach, Purchaser shall give notice to Seller of such Breach with such notice stating the nature of the Breach and the amount involved and reasonable details as to the facts of such Breach known to Purchaser. Purchaser shall allow and shall cause the Group to allow Seller and its professional advisers, each subject to such persons entering into a confidentiality agreement acceptable to Purchaser, to reasonably investigate the matter or circumstances alleged to give rise to such Breach and for such purpose Purchaser shall give, and shall cause the Group to give, subject to being paid their reasonable out of pocket costs and expenses, such information as Seller request and Purchaser, acting reasonably, deems appropriate.

8.4 Seller shall not be liable for any Losses, and Purchaser shall not be entitled to claim compensation for Losses caused by a Breach (such compensation claim a “Purchaser Claim”), if and to the extent that:

8.4.1 the amount of the Purchaser Claim has been paid by a third party or under an insurance policy (minus any amount of increases in any insurance premiums resulting therefrom) of any Group Company which has been in place prior to the Closing Date,

8.4.2 the matter to which the Purchaser Claim relates was expressly and fairly disclosed in this Agreement or in the Exhibit relating to the specific Seller’s Guarantee; Section 442 BGB shall not apply, or

8.4.3 the Purchaser Claim results from or is increased by the passing of, or any change in, after the Signing Date, any law, statute or regulation including any increase in the rates of taxes or any imposition of taxes or any withdrawal or relief from taxes not actually (or prospectively) in effect at the Signing Date.

8.5 If a Group Company or Purchaser are sued or threatened to be sued by a third party including any government agency (a “Third Party Claim”) which is reasonably likely to give rise to a Purchaser Claim, Purchaser shall give Seller as soon as reasonably possible notice of such Third Party Claim. Purchaser shall, and shall procure – to the extent Purchaser is legally in the position to do so - that the Group,

17

Share Purchase Agreement

subject to Purchaser and the Group being paid their reasonable out of pocket costs and expenses by Seller, (i) grant Seller and its representatives, upon reasonable advance notice and during normal business hours, access to all relevant correspondence with the third party and to all other documents reasonably relevant for the defense of the claim, (ii) give Seller reasonable opportunity to comment or discuss with Purchaser any measures which Seller propose to take or to omit in connection with the Third Party Claim and (iii) allow Seller to review any relevant reports and audits or other measures and receive copies of all relevant orders (Bescheide) of any authority. Seller shall thereafter have the right at any time within 10 Business Days after its receipt of a notice from Purchaser pursuant to this Section 8.5, to request that Purchaser or the Group Companies defend against the Third Party Claim and to closely coordinate with Seller regarding such defense. Neither Purchaser nor any Group Company shall consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of Seller, which consent shall not be unreasonably withheld, delayed or conditioned. Purchaser agrees that it shall not be unreasonable for Seller to withhold, delay or condition its consent to any settlement if such proposed settlement would result in the imposition of any monetary damages on Seller, subject Seller to any injunctive relief or result in the admission by Seller of any liability. In addition, in no event shall Seller be liable for any settlement or compromise of a Third Party Claim agreed to without the consent of Seller.

8.6 No liability shall attach to Seller with respect to a Breach unless and until and to the extent that an individual claim or several claims, whether a series of related claims or not, exceeds an amount of USD 50,000 in total.

8.7 The total liability of Seller (i) for all Breaches of any Seller’s Guarantee in Sections 7.1.1 (Guarantees regarding Seller) and 7.1.2 (Corporate) shall not exceed an amount equal to the Purchase Price and (ii) for all Breaches of any Seller’s Guarantee in Sections 7.1.8 (Tax Matters) and under Section 9 (Tax Indemnity) shall not exceed an amount of USD 250,000.

8.8 The total liability of Seller for all Breaches of any Seller’s Guarantee other than those referred to in Section 8.7 shall not exceed an amount of USD 500,000.

8.9 The total liability of Seller for all claims which may arise under this Agreement other than claims under Section 11 (Non-Competition Obligation) shall not exceed the Purchase Price.

8.10 Any claims of Purchaser against Seller under this Agreement shall be time-barred as follows:

8.10.1 claims for Breaches of Seller’s Guarantee in Sections 7.1.1 (Guarantees regarding Seller) and 7.1.2 (Corporate) shall be time-barred 5 years after the Closing Date,

18

Share Purchase Agreement

8.10.2 claims for Breaches of Seller’s Guarantee in Section 7.1.8 (Taxes) and any claims of Purchaser under Section 9 (Tax Indemnity) shall be time-barred six months after the relevant Tax assessment has become final, binding and non-appealable (bestandskräftige und unanfechtbare Festsetzung); and

8.10.3 any claims for Breaches of Seller’s Guarantee not covered under Sections 8.10.1 and 8.10.2 shall be time-barred 18 months after the Closing Date.

8.11 All payments made by Seller to Purchaser under this Section 8 shall constitute a reduction of the Purchase Price. If and to the extent payments are made by Seller to any Group Company, such payments shall be construed and deemed as contribution (Einlage) made by Purchaser to the Company and shall be treated as a reduction of the Purchase Price as between the Parties.

8.12 The Parties agree that the remedies which Purchaser may have against Seller with respect to Breaches are solely governed by this Agreement and that the remedies provided for by this Agreement shall be the exclusive remedies available to Purchaser with respect to a Breach other than Breaches based on gross negligence or willful deceit. For the avoidance of doubt, the claim of Purchaser for specific performance (primäre Erfüllungspflichten) and any claims of Purchaser for a breach of any other obligation of Seller under this Agreement and corresponding damage claims shall be governed by German statutory law and shall remain unaffected by this Section 8.12.

9. TAX INDEMNITY

9.1 Seller shall jointly and severally indemnify and hold harmless Purchaser or, at Purchaser’s election, the Group Companies from 50% of any Taxes and reasonable costs related to asserting such indemnifiable Taxes (including advisers’ fees) which are imposed on the Group Companies either as an own Tax liability or owed as a liability debtor (Haftungsschuldner) if and to the extent

9.1.1 such Taxes relate to periods ending on or before the date of the Closing Financials, subject to the limitations set forth in Section 7.1.8.7; or

9.1.2 such Taxes are triggered by the sale and transfer of the Sold Shares to Purchaser as contemplated under this Agreement, it being understood that Seller will under no circumstances be obliged to indemnify Purchaser or the Group Companies for any Taxes caused by: (i) the waiver of the Pre Closing Claims (as defined in Section 10); (ii) the loss or limitation on use of the Group Companies’ loss carry forwards; or (iii) arising out of Purchaser’s disposition of the Seller’s Claims.

19

Share Purchase Agreement

9.2 Seller’s obligation to indemnify Purchaser under this Section 9 shall not apply if and to the extent that

9.2.1 such Taxes result from any transaction, action or omission (including the change in the exercise of any Tax or accounting election right, the approval or implementation of any reorganization measure or the sale of any asset) taken by Purchaser or the Group Companies after the Closing Date, or

9.2.2 Seller was materially prejudiced by Purchaser’s non-compliance with the procedures of Sections 9.4 and 9.5.

9.3 Any Tax indemnification claim under Section 9 shall be due and payable within ten Business Days after Seller has been notified in writing by Purchaser about the payment obligation and the corresponding payment date and the circumstances giving rise to the payment obligation pursuant and in accordance with this Agreement and has received a copy of the relevant tax assessment notice (Steuerbescheid) of the competent Tax authority (or a copy thereof), but in any case not earlier than 5 Business Days before the Tax to be indemnified is due and payable to the Tax authority.

9.4 The Parties agree to fully cooperate with each other in connection with any Tax matter relating to any time periods ending on or before the Closing Date, including the preparation and filing of any Tax return, conduct of any audit, investigation, dispute, appeal or similar proceedings or any other communication with any Tax authority. Such cooperation shall include, without limitation, providing or making available all relevant books, records and documentation and the assistance of officers and employees reasonably necessary for such cooperation. Each Party shall bear its own costs and expenses incurred in complying with the foregoing obligations and Purchaser agrees that the costs of the Group Companies for completing and filing all Tax returns for the Group Companies financial year ended June 30, 2010 and through the Closing Date shall be borne by the Group Companies. Purchaser agrees to retain all books, records and documentation relating to the Group Companies that may be reasonably relevant in connection with any audit or investigation for which Seller may be responsible hereunder until the expiration of any applicable statute of limitation. Purchaser shall prepare and file, or cause the Group Companies to prepare and file, all Tax returns with regard to Tax periods beginning before the Closing Date and ending after the Closing Date; Purchaser agrees, and shall cause (to the extent it is legally in the position to do so) the Group Companies, not to file such Tax returns without the prior written consent of Seller, such consent not to be unreasonably withheld and

9.5 Seller shall be notified by Purchaser without undue delay of any Tax audit relating to time periods ending on or before the Closing Date after Purchaser or a Group Company has received the relevant information from the Tax authority. Purchaser agrees, and shall cause (to the extent it is legally in the position to do so) the Group Companies, not to give their consent to the findings of any Tax audits relating to time periods ending on or before the Closing Date without the prior written consent of Seller, such consent not to be unreasonably withheld and deemed to be given if not explicitly denied in writing by Seller within a period of ten Business Days after receipt by Seller of a respective written request of Purchaser. Seller shall be obliged to reasonably take into account Purchaser’s interests when making such decision.

9.6 No liability shall attach to Seller under this Section 9 unless and until the damages incurred by the Company under this Section 9 exceed an amount of USD 50,000 in total, in which case Seller’s liability shall be 50% of such damages in excess of USD 50,000.

9.7 The total liability of Seller for all Breaches of any Seller’s Guarantee in Sections 7.1.8 (Tax Matters) and under this Section 9 shall not exceed an amount of USD 250,000.

10. WAIVER

10.1 To the extent legally possible, Seller hereby irrevocably declares that (i) it will not make or pursue any Pre-Closing Claims against any Group Company and that (ii) it hereby unconditionally and irrevocably waives any Pre-Closing Claims it may have against any Group Company other than the Seller’s Claims, which Seller sells and assigns to Purchaser as set forth in this Agreement. “Pre-Closing Claims” shall be any and all claims (other than the Seller’s Claims), whether actual or contingent, whether current or future, whether due or not and whether known to Seller or not, that Seller may have against any Group Company that has arisen or arises directly or indirectly out of, or relates directly or indirectly to, any circumstance, agreement, action, omission, or event occurring or existing on or prior to the Closing Date, including pursuant to any instrument or agreement entered into by Seller or any officer or director of the Company.

This TRADEMARK LICENSE AGREEMENT (the “Agreement”), dated as of March 9, 2011 and effective as of the Closing Date (as defined in the Share Purchase Agreement between Licensor and Exceet Group AG dated March 9, 2011 – “SPA”) (“Effective Date”) is entered into by and between Authentidate Holding Corp., a Delaware corporation, having a place of business at 300 Connell Drive, 5th Floor, Berkeley Heights, NJ 07922 (“Licensor”) and AuthentiDate International AG, having a place of business at Rethelstraße 47, 40237 Düsseldorf, Germany, and AuthentiDate Deutschland GmbH, having a place of business at Rethelstraße 47, 40237 Düsseldorf, Germany (collectively, “Licensee”).

WHEREAS, Licensee desires to obtain a license to use the Mark.

NOW, THEREFORE, for and in consideration of the foregoing and the respective promises and covenants contained in this Agreement, Licensor and Licensee hereby agree as follows:

1. Grant of License.

1.1 Non-Exclusive Perpetual License. Licensor grants to Licensee a non-exclusive, royalty-free, non-transferrable, non-sublicensable, perpetual (subject to a termination under Sections 9.1 or 9.2) license (the “License”) in the Field of Use (as defined herein) to use the Mark only within the European Economic Area, Croatia, Georgia, Iceland, Liechtenstein, Russia, Serbia, Switzerland, Turkey and Ukraine (the “Territory”), in the following form:

(i) For use as company names “AuthentiDate International AG” and “AuthentiDate Deutschland GmbH”.

(ii) For use with IT products and services as currently provided by Licensee, including updates and upgrades to the extent such updates and upgrades do not include additional features or functionality that are competitive with the products and services being developed, offered or provided by Licensor, that fall within the scope of the Company Business (as defined in the SPA) and as further or newly developed by Licensee to the extent that such further or newly developed products and services are not similar to or competitive with the products and services being developed, offered or provided by Licensor at such time, as reasonably determined by Licensor, with proof of such development, offer or provisioning to be provided by Licensor upon reasonable request of Licensee: “AuthentiDate”.

(iii) For use as or as part of domain names <www.authentidate.de>, <www.authentidate.eu> and as identified in Exhibit B as well as any other additional top level domains that can be registered in the Territory with “authentidate-ag” as or as an element of the domain name.

For purposes of this Agreement, the term “Field of Use” shall mean the uses as set forth in Sections 1.1(i), (ii) and (iii).

1

1.2 Initial Exclusive License Term. The license provided under Section 1.1 shall be exclusive in the Territory until three (3) years following the Effective Date; provided that the exclusivity of this license shall not apply to Licensor, its affiliates and subsidiaries other than with respect to Licensor’s non-compete obligation as set forth in Section 11.1 of the SPA.

1.3 Option to Extend Exclusive License Term. The Licensee shall have the right to extend the exclusivity provided under Section 1.2 for one (1) or more years against payment of a license fee in an amount to be determined by the parties pursuant to good faith negotiations. The Licensee may chose to opt for further one year extension periods under the same terms. Each option to extend has to be declared by the Licensee to the Licensor in writing at least two (2) weeks prior to the expiration of any ongoing exclusivity period. If the parties agree upon the terms for the extension of the exclusivity, the payments hereunder for each extension of the exclusivity period shall be made not less than five (5) days prior to termination of the prior exclusivity period. Notwithstanding any agreement regarding the extension of the exclusivity of this Agreement, in case of a delayed payment of such license fees, the exclusivity of the license granted hereunder and the obligation to pay the license fees shall automatically terminate.

Corp.” and (iii) in all other documentation and press releases in which Licensee includes attribution but not specifically identifying the name of the owner of a trademark, including Licensee’s name, such as for example, “All Trademarks are the property of their respective registered owners”, the same attribution as used for all other trademarks in such documentation or press release.

Licensee or Licensor, as the case may be, shall provide reasonable cooperation in all infringement proceedings and preparations for such proceedings brought or contemplated to be brought by the other party.

6. Disclaimer, Covenant.

3

7.2 The Licensor shall not assign the Mark in the Territory to a third party prior to providing the Licensee with the opportunity to purchase the Mark in the Territory under terms not less favorable to Licensee than the terms offered or proposed to be offered to such third party; provided that Licensor shall have no such obligation in the case of a merger or acquisition of the business of Licensor or a sale or offer of sale of all of the stock or assets of the business of Licensor in conjunction with which the Marks are then being used. In case the Licensee rejects the purchase, Licensee is unwilling to agree to Licensor’s terms, or the parties are unable to conclude an agreement within thirty (30) days from presentation of the initial offer by Licensor, the Licensor may assign the Mark to a third party on similar terms and including the rights and obligations under this Agreement. The terms of the Agreement shall survive any such assignment by Licensor.

Exhibit 10.2

FINAL VERSION 3/9/11

INTELLECTUAL PROPERTY LICENSE AGREEMENT

This INTELLECTUAL PROPERTY LICENSE AGREEMENT (“Agreement”), dated as of March 9, 2011 and effective as of the Closing Date (as defined in the Share Purchase Agreement between Exceet Group AG and Licensee dated March 9, 2011 - “SPA”) (“Effective Date”) is entered into by and between AuthentiDate International AG together with Authentidate Deutschland GmbH, each having a place of business at Rethelstraße 47, 40237 Düsseldorf, Germany (collectively, “Licensor”) and Authentidate Holding Corp., a Delaware corporation, having a place of business at 300 Connell Drive, 5th Floor, Berkeley Heights, NJ 07922 (“Licensee”).

WHEREAS, Licensee has provided funding to Licensor over an extended period of time, including throughout the period of development of Licensor’s Intellectual Property Rights (as defined below);

WHEREAS, Licensee and Licensor have entered into an agreement titled Trademark License Agreement on the Effective Date, pursuant to which Licensee has licensed to Licensor rights under Licensee’s trademarks;

WHEREAS, Licensor owns the Intellectual Property Rights (as defined below), relating to technology offered and sold by Licensor that are used in its business, and desires to grant to Licensee a license to the Intellectual Property Rights; and

WHEREAS, Licensee desires to obtain a license from Licensor to the Intellectual Property Rights.

NOW, THEREFORE, for and in consideration of the foregoing and the respective promises and covenants contained in this Agreement, Licensor and Licensee hereby agree as follows:

1. Grant of License.

1.1 Non-Exclusive Perpetual License. Licensor grants Licensee a non-exclusive, royalty-free, non-transferrable, perpetual (subject to the termination under Sections 8.1 or 8.2) license to use the intellectual property rights as defined in Exhibit A (the “Intellectual Property Rights”), worldwide except the European Economic Area, Croatia, Georgia, Iceland, Liechtenstein, Russia, Serbia, Switzerland, Turkey and Ukraine (the “Territory”).

1.2 Sub-Licensing. Licensee shall have the right to sub-license the Intellectual Property Rights to each of its affiliates and subsidiaries, and each of Licensee, its affiliates and subsidiaries shall have the right to include the Intellectual Property Rights as part of their own products and services and sell such products and services to their customers for use by such customers and for resale by such customers through all subsequent levels of the supply chain.

[*CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION, WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH ASTERISKS [****], HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.]

2. Non-Competition.

2.1 For a duration of two (2) years following the Effective Date, Licensor shall refrain, directly or indirectly, whether as principal or agent, and whether alone or jointly with others, to carry on or be engaged, concerned or interested in any business in the Territory relating to the Intellectual Property Rights that is competitive with the business of Licensee.

2.2 In the event of any breach or threatened breach by Licensor of its obligations under this Section 2, Licensee shall be entitled to seek injunctive relief in addition to any other remedy to which it may be entitled under law.

2.3 The parties agree that the restrictions contained in this Section 2 are no greater than is reasonable and necessary for the protection of the interest of Licensee, but if any such restriction shall be held to be void but would be valid if deleted in part or reduced in application, such restriction shall apply with such deletion or modification as may be and to the minimum extent necessary to make it valid and enforceable.

2.4 Notwithstanding the foregoing, however, Licensee agrees that nothing in this Agreement (including Section 2) shall restrict the Licensor from continuing to conduct its business or otherwise exploiting any of its Intellectual Property Rights from and after the Effective Date (including in the Territory) as it conducted its business and exploited its Intellectual Property Rights prior to the Effective Date.

3. Taxes. Licensor is not responsible for any sales, use, value-added, personal property or other taxes imposed on either Licensee’s or any sub-licensees’ use, possession, offer for sale, or sale of the Intellectual Property Rights. Each party shall be solely responsible for any taxes based on its own net income.

4. Infringement Proceedings. Licensee shall notify Licensor of any infringement of the Intellectual Property Rights as it comes to the attention of Licensee. The Licensor shall either prosecute the infringement of the Intellectual Property Rights, at its own expense and discretion, or shall allow Licensee to prosecute the infringement of the Intellectual Property Rights, at Licensee’s expense. Licensee or Licensor, as the case may be, shall provide reasonable cooperation in all infringement proceedings and preparations for such proceedings brought or contemplated to be brought by the other party.

Should Licensor fail, within such thirty (30) day period, to so modify the software, methods, processes and systems such that they no longer infringe, misappropriate or violate such third party intellectual property or proprietary rights, Licensor shall be liable to Licensee for an amount not to exceed [****] in total over the term of this Agreement to cover Licensee’s costs and expenses to defend against any third party claims, to make such modifications, remove or replace such infringing software, methods, processes and systems and to cover Licensee’s costs and expenses associated therewith, including reasonable attorney and expert fees, costs, liens, judgments, settlements, and penalties.
