Exhibit 10.1 PREFERRED STOCK PURCHASE AGREEMENT This preferred stock purchase agreement is dated May 12, 2000, and is between TERACOMM RESEARCH, INC., a Delaware corporation ("TeraComm"), and ATLANTIC TECHNOLOGY VENTURES, INC., a Delaware corporation ("Atlantic"). Atlantic wishes to purchase from TeraComm, and TeraComm wishes to issue to Atlantic, shares of TeraComm's Series A preferred stock, par value $.001 per share (the "TeraComm Preferred Stock"). TeraComm and Atlantic therefore agree as follows: ARTICLE 1 AUTHORIZATION AND SALE OF SHARES 1.1 Authorization. TeraComm has duly authorized the sale and issuance of 1,400 shares of TeraComm Preferred Stock. The TeraComm Preferred Stock has the rights, restrictions, privileges, and preferences set forth in the Restated Certificate of Incorporation of TeraComm attached hereto as Exhibit A (the "Restated Certificate of Incorporation"). TeraComm has adopted and filed the Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. 1.2 Sale of Shares. Subject to the terms of this agreement, TeraComm hereby issues to Atlantic, and Atlantic hereby purchases from TeraComm, 1,400 shares of TeraComm Preferred Stock (the "Shares") for a purchase price (the "Purchase Price") consisting of the following: (1) $5,000,000 in cash, $250,000 of which Atlantic has already paid to TeraComm, and the remaining $4,750,000 of which Atlantic shall pay to TeraComm in immediately available funds in the amounts and on the dates stated in Schedule 1.2(a) (each installment of the remaining $4,750,000, a "Subsequent Payment"); (2) 200,000 shares of Atlantic common stock (the "Purchase Price Shares"); and (3) a warrant for the purchase of a further 200,000 shares of Atlantic common stock (the "Purchase Price Warrant"). (b) If Atlantic fails to timely make any Subsequent Payment, it may not make any further Subsequent Payments and it will be deemed to have surrendered to Teracomm a proportion of the Shares (with any fractional share rounded up) equal to the proportion of the dollar value of the Purchase Price that is represented by the missed Subsequent Payment and all other unpaid Subsquent Payments. This surrender will be Teracomm's sole remedy for the failure by Atlantic to timely make any Subsequent Payment. For purposes of this Agreement, the dollar value of the Purchase Price is $6,795,000. (c) If TeraComm is dissolved and liquidated before Atlantic has made each Subsequent Payment it is required to make pursuant to Section 1.2(a), the maximum Series A Preferred Stock Liquidation Amount payable to Atlantic will be calculated by multiplying the Preferred Stock Liquidation Amount that it would otherwise be entitled to by a fraction, the numerator of which is $1,795,000 plus $250,000 plus the amount of each Subsequent Payment made by Atlantic, the denominator of which is $6,795,000. 1.3 Dividend. TeraComm may not distribute to its common stockholders as a dividend the Purchase Price Shares and the Purchase Price Warrant until such time as all holders of TeraComm common stock have made to Atlantic customary investment representations in a form reasonably acceptable to Atlantic. If by 30 days after the date of this agreement Atlantic has not received signed investment representations from each holder of TeraComm common stock, TeraComm may thereafter sell the Purchase Price Shares and issue the proceeds as a dividend to holders of TeraComm common stock, on condition that the sale is conducted in compliance with all applicable securities laws.

(a) In order to be entitled to indemnification under this Article 5 in connection with a claim made by any Person against any Person entitled to indemnification pursuant to this Article 5 (an "Indemnified Party"; any such claim, a "Third Party Claim"), that Indemnified Party must do the following: (1) notify the Person or Persons obligated to indemnify it (the "Indemnifying Party") in writing, and in reasonable detail, of that Third Party Claim promptly but in any event within 10 business days after receipt of notice of that Third Party Claim, except that any failure to give any such notification will only affect the Indemnifying Party's obligation to indemnify the Indemnified Party if the Indemnifying Party has been prejudiced as a result of that failure; and (2) deliver to the Indemnifying Party promptly but in any event within 10 business days after the Indemnified Party receives them a copy of all notices and documents (including court papers) delivered to that Indemnified Party relating to that Third Party Claim. (b) No Indemnified Party will be entitled to indemnification under this Article 5 in connection with any Third Party Claim that it notifies the Indemnifying Party of more than two years after the date of this agreement. (c) In the event of a Third Party Claim against one or more Indemnified Parties, the Indemnifying Party will be entitled to participate in the defense of that Third Party Claim and, if they so choose, to assume at their expense the defense of that Third Party Claim with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party. If the Indemnifying Party so elects to assume the defense of a Third Party Claim, the Indemnifying Party will not be liable to the Indemnified Party for any legal expenses 19 subsequently incurred by the Indemnified Party in connection with the defense of that Third Party Claim, except that if, under applicable standards of professional conduct, there exists a conflict on any significant issue between the Indemnified Party and the Indemnifying Party in connection with that Third Party Claim, the Indemnifying Party shall pay the reasonable fees and expenses of one additional counsel to act with respect to that issue to the extent necessary to resolve that conflict. If the Indemnifying Party assumes defense of any Third Party Claim, the Indemnified Party will be entitled to participate in the defense of that Third Party Claim and to employ counsel, at its own expense, separate from counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party will be entitled to control that defense. The Indemnifying Party will be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party did not assume the defense of any Third Party Claim (other than during any period in which the Indemnified Party failed to give notice of the Third Party Claim as provided above and a reasonable period after such notice). If the Indemnifying Party chooses to defend or prosecute a Third Party Claim, all the parties shall cooperate in the defense or prosecution of that Third Party Claim, including by retaining and providing to the Indemnifying Party records and information reasonably relevant to that Third Party Claim, and making employees available on a reasonably convenient basis. If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will agree to any settlement, compromise or discharge of that Third Party Claim that the Indemnifying Party recommends and that by its terms obligates the Indemnifying Party to pay the full amount of liability in connection with that Third Party Claim, except that the Indemnifying Party may not without the Indemnified Party's prior written consent agree to entry of any judgment or enter into any settlement that provides for injunctive or other nonmonetary relief affecting the Indemnified Party or that does not include as an unconditional term that each claimant or plaintiff give to the Indemnified Party a release from all liability with respect to that Third Party Claim. Whether or not the Indemnifying Party has assumed the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, that Third Party Claim without the Indemnifying Party's prior written consent. (d) In order for one or more Indemnified Parties to be entitled to any indemnification under this agreement in respect of a claim that does not involve a Third Party Claim (a "Claim"), the Indemnified Party must reasonably promptly notify the Indemnifying Party of that Claim, and describe in reasonable detail the basis for that Claim, except that any failure to give any such notification will only affect the Indemnifying Party's obligation to indemnify the Indemnified Party if the Indemnifying Party has been prejudiced as a result of that failure. No Indemnified Party will be entitled to indemnification under this Article 5 in connection with any Claim if it notifies the Indemnifying Party of that Claim more than two years after the date of this agreement. If the Indemnifying Party does not dispute that the Indemnified Party is entitled to indemnification with respect to that Claim by notice to the Indemnified Party prior to the expiration of a 30-calendar-day period following receipt by the Indemnifying Party of notice from the Indemnified Party of that Claim, that Claim will be conclusively deemed a liability of the Indemnifying Party and the Indemnifying Party shall pay the amount of that liability to the Indemnified Party on demand or, in the case of any notice in which the amount of the Claim (or any portion thereof) is estimated, on such later date as the amount of the Claim (or any portion thereof) becomes finally determined. If the Indemnifying Party has timely disputed their liability with respect to the Claim, the Indemnifying Party and the 20 Indemnified Party shall proceed in good faith to negotiate a resolution of the Claim and, if the Claim is not resolved through negotiations, the Indemnified Party may pursue such remedies as may be available to enforce their rights to indemnification under this agreement. 5.5 Limitation on Indemnification. (a) Each Indemnifying Party's exclusive remedy with respect to any claims of that Indemnifying Party under this Agreement will be pursuant to the indemnification provisions of this Article 5. (b) Neither Indemnifying Party will be liable for any obligations under this Article 5 until the aggregate of any amounts it is required to pay to any Indemnified Party under this Article 5 (the "Aggregate Indemnification Amount") exceeds $50,000, after which it will be obligated to pay the total Aggregate Indemnification Amount. (c) Once the Aggregate Indemnification Amount of either Indemnifying Party exceeds $6,795,000, that Indemnifying Party will not be required to pay any Indemnified Party any additional amounts pursuant to this Article 5.
