9.2 Indemnity by Seller. Seller shall indemnify and hold harmless Purchaser and the Company from and against, and shall reimburse Purchaser or the Company on demand for any loss, liability, damage or expense, including reasonable attorneys' fees and costs of investigation incurred as a result thereof (other than Purchaser's or the Company's administrative costs and expenses) that Purchaser or the Company shall incur or suffer (collectively, "▇▇▇▇▇▇▇'▇ Recoverable Losses"), arising out of or resulting from (i) any material breach or inaccuracy of any representation or warranty of Seller contained in Section 2 hereof or in any document, certificate, schedule or instrument delivered by or on behalf of Seller pursuant hereto; (ii) any default or breach of an agreement or covenant made by Seller under or pursuant to this Agreement; or (iii) any loss, cost, claim, liability or obligation arising out of or relating to the activities of the Company on or prior to the Closing Date that is not disclosed or reflected on the Balance Sheet or otherwise specifically disclosed. Purchaser agrees that for any particular loss coming within this Section 9.2, Seller shall be required to indemnify for such loss only once and only either for the benefit of Purchaser or the Company, but not both.

Any party hereto shall give Seller or Purchaser, as the case may be (the "Indemnitor"), written notice (the "Claim Notice") of any claim (including the receipt of any demand) or the commencement of any action with respect to which indemnity may be sought (the "Claim" or the "Claims). The Claim Notice shall state (i) the aggregate amount of ▇▇▇▇▇▇▇'▇ Recoverable Losses or Seller's Recoverable Losses (in either case, "Recoverable Losses") as to which indemnification is being sought (which amount may be estimated and updated from time to time), (ii) the components of the amount of Recoverable Losses for which indemnification is being sought (which components may be estimated and updated from time to time); and (iii) the specific grounds upon which the Claim for indemnification is being made. The right to indemnification for a Claim shall be deemed to be accepted by the Indemnitor unless, within 30 days after the Indemnitor's receipt of the Claim Notice, the Indemnitor shall notify the claimant in writing that it objects to the right to indemnification with respect to the Claim.

The successful or prevailing party or parties shall be entitled to recover all attorneys' fees, expert witness fees and other costs incurred in such action, in addition to any other relief to which it or they may be entitled.

SECTION 10

POST-CLOSING COVENANTS

10.1 Intercompany Loan. On the Closing Date Purchaser shall provide by wire transfer an intercompany loan to the Company of U.S. $1 million and shall cause the Company within seven days of the Closing Date to use the full proceeds of that loan to pay a portion of the existing indebtedness of the Company to Seller which as of the Closing Date will amount to CHF 2,363,000. The remaining balance of such indebtedness of the Company to Seller (hereinafter referred to as "Seller Indebtedness") shall be considered due and owing only at the times and to the extent provided in Section 10.2 below.

10.2 PEC Cash Proceeds. The Company has sold its PEC (power capacitor) business to EPCOS for a series of cash installments consisting of 500,000 Euros due in April 2002, 700,000 Euros due in August 2002 and 300,000 Euros due in October 2002. Such installment payments are hereinafter collectively referred to as the "PEC Installment Payments". The Company remains liable for certain liabilities relating to the PEC business, including without limitation social obligations to former employees, obligations under long-term purchase contracts and product warranties and obligations to refrain from engaging in a competitive activity in the PEC business (power capacitor business) (hereinafter, the "PEC Liabilities"). The Company retained and did not sell to EPCOS its PEC inventories and PEC production machinery, which the Company is holding for future sales to third parties. The proceeds from the sale of the PEC inventories and PEC production machinery are

hereinafter referred to collectively as the "PEC Additional Proceeds". Purchaser agrees to cause the Company to pay to Seller the following amounts:

(a) on August 31, 2002, the Company will pay to Seller the excess of (i) 1,200,000 Euros plus any PEC Additional Proceeds received on or prior to that date, over (ii) PEC Liabilities paid or accrued as of that date;

(b) on March 31, 2003, the Company will pay to Seller the excess of (i) 300,000 Euros plus any PEC Additional Proceeds received after August 31, 2002 and on or before March 31, 2003, over (ii) PEC Liabilities paid or accrued after August 31, 2002 and on or before March 31, 2002.

The above payments shall first be credited to the repayment of Seller Indebtedness, and to the extent that such payments exceed Seller Indebtedness, they shall be considered an addition to the Purchase Price and shall be paid to Seller to the extent of the appropriate portion thereof pursuant to Section 1.2 hereof. In the event that the PEC Installment Payments are delayed or not paid by EPCOS, the obligation of the Company under clauses (a) and (b) above shall be proportionately delayed or excused. In the event that the above payments do not fully repay Seller Indebtedness, Seller agrees that any remaining balance of such indebtedness shall be canceled and forgiven. If the sum of the PEC Installment Payments and PEC Additional Proceeds is not sufficient to discharge all of the PEC Liabilities, Seller agrees that, in addition to canceling and forgiving the remaining balance of Seller Indebtedness and notwithstanding any limitations under Section 9.2 above, it shall remain liable for and shall indemnify Purchaser against any remaining PEC Liabilities.

10.3 Registration of ▇▇▇▇▇▇▇ Shares. Within 10 days following the Closing Date, Purchaser shall file a registration statement for the resale of the ▇▇▇▇▇▇▇ common stock received at Closing by Seller as a part of the Purchase Price. Seller agrees to cooperate in the preparation and filing of such registration statement, including providing required information concerning the shares owned and to be sold by Seller. Purchaser shall use its best efforts to cause such registration statement to become effective as soon as possible, and upon a declaration of effectiveness by the SEC, Purchaser will use its best efforts to keep such registration statement effective for one year from the Closing Date. Seller understands and acknowledges that there may be periods following the effectiveness of such registration statement in which Purchaser is required to suspend any use of the prospectus under the registration statement and any sales thereunder into the market until the information disclosed under such prospectus or incorporated by reference into such prospectus is corrected or updated. After expiration of one year from the Closing Date, Seller understands that it may sell into the public market up to a number of shares per 90-day period equal to 1% of Purchaser's total outstanding shares, and following another year thereafter, Seller may sell such stock into the public market without restriction.

10.4 Repayment of the Closing Loan. Seller hereby agrees that, promptly upon the effectiveness of the S-3 registration statement described in Section 10.3 of this Agreement, it shall diligently seek to sell in the public trading market 225,000 shares of ▇▇▇▇▇▇▇ common stock within a period of 90 days at a price of at least $13.35 per share. Seller agrees not to sell such stock at less than $13.35 per share without the prior consent of Purchaser. If Seller desires to sell at a price lower than $13.35 per share and Purchaser does not give its consent, Seller may proceed with such sale but the proceeds will not be applied to the Closing Loan and no shares will be released from the Pledge Agreement. Seller further agrees that it will not distribute to its or the Company's shareholders more than 250,000 shares of the Purchaser received as part of the Purchase Price until such time as the Closing Loan is repaid in full. The intention of this provision and the rest of this Section 10.4 is to require Seller to repay the Closing Loan in full from the sale of up to 225,000 shares of ▇▇▇▇▇▇▇ common stock before any shares are sold at a price below $13.35 per share (unless Purchaser consents) and before more than 250,000 shares of ▇▇▇▇▇▇▇ common stock are distributed by Seller to its or the Company's shareholders.

Purchaser and Seller each agree to cooperate with the other in order to facilitate the sale of such stock within the 90-day period at the maximum price possible with the minimum adverse impact on the

trading price of such stock. Seller shall notify Purchaser immediately after any sale of stock and shall regularly provide information on the number of shares sold and the selling price. At the end of each 30-day period within said 90-day period, Seller shall provide a written summary of the stock sales that occurred in that 30-day period that are creditable toward payment of the Closing Loan, including a total of the proceeds received by Seller, and such proceeds shall be paid to Purchaser as an installment payment of the principal and accrued interest on the Note. At the time of each such installment payment, Purchaser shall release and return to Seller from the Pledged Stock a number of shares equal to the number of shared sold by Seller in such 30-day period. The due date of the Note shall correspond to the end of said 90-day period, and if at that time, Seller has not sold a total of 225,000 shares that are applied to the Note, the due date of the Note shall be extended for 30 days. The Note shall only be extended for one 30-day period if said 225,000 shares have not been sold, and the term for the Note shall not be extended beyond a total of 120 days from the effective date of the S-3 registration statement. If, during the term of the Note, sales of ▇▇▇▇▇▇▇ common stock by Seller result in either (i) payment of the total principal and accrued interest due under the Note, or (ii) the sale of a total 225,000 shares of ▇▇▇▇▇▇▇ common stock that are applied to the Note, then the Note shall at that time be considered satisfied and paid in full and the Pledged Stock shall be released to Seller. Any portion of the principal or accrued interest not yet paid if clause (ii) applies shall be forgiven. In the event that neither clause (i) nor (ii) has occurred within the term of the Note (as extended), then Purchaser and Seller agree that Purchaser shall retain any shares of the Pledged Stock not yet released in full satisfaction of any remaining obligations of Seller under the Note.

10.5 Use of Montena Name. Seller agrees that the Company may, following the Closing, continue to use the name "Montena Components SA" in association with the lines of business being pursued by the Company as of the Closing Date. The right of the Company to such use shall continue indefinitely and extend to all countries of the world.

10.6 ▇▇▇▇▇▇▇ Board Seat. As soon as practicable following the Closing, Purchaser agrees to appoint a representative of Seller to the Board of Directors of Purchaser and shall nominate and recommend to the stockholders the election of such nominee, or a replacement reasonably acceptable to Purchaser, to the Board of Directors at each subsequent annual meeting during the time which Seller continues to hold at least 1,000,000 ▇▇▇▇▇▇▇ common stock received as the Purchase Price hereunder.

10.7 Matran Facility. Seller agrees that the portion of the Company's operations now located at the Matran facility (known as the Metar group) may continue its occupancy in the same manner as currently exists for no rent or other occupancy charge until the earlier of (i) March 31, 2003, or (ii) the closing of a sale of the Matran facility by Seller.

10.8 Board of Directors of the Company. As soon as practicable following the Closing, Seller agrees to arrange for the resignation of all members of the Company's Board of Directors from the Board except for ▇▇▇▇▇▇ ▇▇▇▇▇▇. Upon those resignations, Purchaser shall appoint two new members of such Board, who are anticipated to be ▇▇▇▇ ▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇. Purchaser shall give full release to all members of the Company Board for their activities performed during the financial year 2001/02.

To the extent that each share of Purchaser stock issued as part of the Purchase Price (plus any stock of Purchaser's subsidiary, PurePulse Technologies, Inc., subsequently received as a distribution with respect to Purchaser stock) held by Seller on September 1, 2003 has a market value (based on the average 30 trading-day closing price ending on September 1, 2003—the "30 Day Measurement Price") of less than $9 per share, then Purchaser will issue to Seller such number of additional Purchaser shares (based on the 30 Day Measurement Price) equal, in total value, to (i) the difference between $9 and the 30 Day Measurement Price multiplied by (ii) such number of shares held by Seller on September 1, 2003; provided, however, that such adjustment will in no event be greater than 500,000 shares."

4. Section 5.5 "Loan at Closing" of the Agreement is hereby amended to change the number of shares of Purchaser in the sixth line of said section that will constitute Pledged Shares from the number "225,000" to the number "300,000".

5. Section 10.4 "Repayment of the Closing Loan" of the Agreement is hereby amended in the following two respects: (i) each time the number "225,000" appears relating to the number of shares of

Purchaser common stock to be sold in connection with the repayment of the Closing Loan, such number shall be changed to the number "300,000"; and (ii) each time the amount "$13.35 per share" appears relating to the minimum price at which such shares may be sold and the proceeds applied to the Closing Loan without the consent of Purchaser, such amount shall be changed to the amount "$10.00 per share".

6. Exhibits "A" and "B" to the Agreement are hereby amended in their entirety to read as set forth as Exhibits "A" and "B" to this Amendment.

7. Except as specifically set forth in this Amendment, each and every term, condition and provision of the Agreement remains unchanged and in full force and effect.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the date first above written.

PROMISSORY NOTE

$3,000,000 U.S.
July , ▇▇▇▇

▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇

FOR VALUE RECEIVED, the undersigned, ▇▇▇▇▇▇▇ ▇▇, a corporation organized under the laws of Switzerland, ("Maker") hereby promises to pay to the order of ▇▇▇▇▇▇▇ Technologies, Inc., a Delaware corporation, ("Holder") at its offices located at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or such other place as Holder may designate in writing from time to time, the principal sum of Three Million Dollars, U.S., ($3,000,000) plus accrued interest, on the terms and conditions of this Promissory Note ("Note"). Interest shall accrue under this Note at the rate of 6.5% per annum, and accrued interest shall be paid with each installment payment of principal

This Note evidences the Closing Loan as defined in Section 5.5 of that certain Stock Purchase and Barter Agreement dated the date of this Note between Maker and Holder (the "Stock Purchase Agreement"). Maker's repayment obligation under this Note is secured by a pledge of 300,000 shares of Holder common stock (the "Pledged Shares") under that certain Stock Pledge Agreement dated the date of this Note between Maker and Holder (the "Stock Pledge Agreement").

The repayment of principal and accrued interest under this Note shall be coordinated with the sale into the public trading market of shares of Holder common stock issued to Maker at the closing of the Stock Purchase Agreement. Pursuant to the Stock Purchase Agreement, Holder has committed to register resales of Holder common stock issued to Maker under the Stock Purchase Agreement on a registration statement on Form S-3 to be filed and effective as soon as possible after the date hereof. Maker has committed to sell up to 300,000 shares of Holder common stock within 90 days of the effective date of such registration statement (the "Resale Effective Date") and to use the proceeds of such sales to pay the principal and interest under this Note.

Accordingly, Maker shall make installment payments within 10 working days following each successive 30-day period during the term of this Note. Such installment payments shall be in the amount of the net proceeds of sales of Holder common stock made by Maker during such 30-day period, including sales at a per-share price less than $10.00, which are agreed by Purchaser to be subject to such installment payment treatment. Upon such an installment payment, Holder shall release from the Stock Pledge Agreement a number of Pledged Shares equal to the number of shares of Holder common stock sold in connection with such installment payment. Each such installment payment shall first be applied to accrued interest hereunder and then to unpaid principal. This Note shall be considered fully paid and satisfied upon the payment through said installments of the entire unpaid principal and accrued interest hereunder or the sale by Maker of a total of 300,000 shares of Holder common stock. If (i) a total of 300,000 shares of Holder common stock applicable to installment payments hereunder has not been sold by the date that is 90 days following the Resale Effective Date, and (ii) the total of accrued interest and principal under this Note has not been repaid by such date, the term of this Note shall be extended for an additional 30 days. If neither event in clause (i) or (ii) above shall have occurred by the expiration of a 120-day period from the Resale Effective Date, then Maker agrees that Holder shall transfer back to itself any Pledged Shares then remaining under the Stock Pledge Agreement, and Holder agrees that any remaining balance of principal and accrued interest shall, upon such transfer back, be considered fully paid and satisfied and this Note considered paid in full.

In the event of default of Maker in the timely payment of any amount hereunder or the occurrence of an Event of Default as defined in the Pledge Agreement, the entire unpaid balance of principal and accrued interest under this Note shall be immediately due and payable, together with costs of collection, including, but not limited to, reasonable attorneys' fees, costs and expenses. Maker waives presentment; demand; notice of dishonor; notice of default or delinquency; notice of acceleration; notice of protest and non-payment; notice of costs, expenses, or losses and interest; and diligence in taking any action to collect any sums owing under this Note. Any principal or interest not paid when due shall bear a default rate of interest at the maximum rate permitted by applicable law.

The Maker shall at any time be permitted to prepay, without penalty or charge, all or any portion of the amount due under this Note.

This Note is made in the State of California, U.S.A. and it is mutually agreed that California law shall apply to the interpretation of the terms and conditions of this Note.

IN WITNESS WHEREOF, this Note is executed the above date first written.

STOCK PLEDGE AGREEMENT

THIS STOCK PLEDGE AGREEMENT (this "Pledge Agreement") is made as of July , 2002, between ▇▇▇▇▇▇▇ ▇▇, a corporation organized under the laws of Switzerland, as pledgor ("Pledgor"), and ▇▇▇▇▇▇▇ Technologies, Inc., a Delaware corporation, as pledgee ("Pledgee").

R E C I T A L S:

A. Pledgor is the beneficial owner of Three Hundred Thousand (300,000) shares (the "Shares") of common stock, $0.10 par value per share of Pledgee.

B. Pursuant to the terms of that certain Secured Promissory Note in the amount of $3,000,000 U.S. of even date herewith delivered by Pledgor to Pledgee (the "Note"), Pledgor has agreed to make payments of principal and interest to Pledgee as provided in the Note.

C. Pursuant to the terms of the Note, Pledgor is required to execute this Pledge Agreement to secure payment in full of all obligations under the Note, whether for principal, interest, fees, expenses or otherwise and to ensure compliance with the terms and conditions of this Pledge Agreement.

A G R E E M E N T:

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants and conditions contained herein, the parties hereto agree as follows:

1. Grant of Security Interest in the Shares. Pledgor hereby grants to Pledgee a security interest in the Shares, pledges and hypothecates the Shares to Pledgee, and deposits the certificates evidencing the Shares (the "Certificates") with Pledgee as collateral security for the payment by Pledgor of all obligations existing under the Note, whether for principal, interest, fees, expenses or otherwise, and the satisfaction of all obligations of Pledgor under this Pledge Agreement. The Certificates, together with one or more stock assignments duly executed in blank with signatures appropriately guaranteed or witnessed, are being delivered herewith to Pledgee, to be retained by Pledgee as the pledgeholder for the Shares.

2. Representation and Warranty of Pledgor. Pledgor represents and warrants to Pledgee that the Shares are free and clear of all claims, mortgages, pledges, liens and other encumbrances of any nature whatsoever, except the liens and restrictions set forth herein and in the Note.

3. Voting of Shares. So long as there shall exist no Event of Default (as hereinafter defined), Pledgor shall be entitled to exercise, as Pledgor deems proper but in a manner not inconsistent with the terms hereof, Pledgor's rights to voting power with respect to the Shares. Pledgee, and not Pledgor, shall be entitled to vote the Shares at any time that there exists an Event of Default.

4. Dividends. So long as there shall exist no Event of Default, Pledgor shall be entitled to receive any dividend (ordinary or extraordinary, whether paid in cash, stock or property) or other distribution with respect to the Shares. If there exists an Event of Default, such dividend or other distribution shall be delivered to Pledgee to be held as additional collateral security under this Pledge Agreement.

5. Pledgee's Duties. So long as Pledgee exercises reasonable care with respect to the Shares in its possession, Pledgee shall have no liability for any loss or damage to such Shares, and in no event shall Pledgee have liability for any diminution in value of the Shares occasioned by economic or market conditions or events. Pledgee shall be deemed to have exercised reasonable care within the meaning of

the preceding sentence if the Shares in its possession are accorded treatment substantially equal to that which Pledgee accords its own property.

6. Partial Release of Shares. The Note provides for installment payments of the indebtedness thereunder based on sales of shares of Pledgee common stock held by Pledgor other than the Shares. Upon the making of each installment payment under the Note, Pledgee agrees to release and deliver back to Pledgor, free and clear of the security interest created by this Pledge Agreement, that number of the Shares that equals the number of other such shares sold by Pledgee in connection with such installment payment.

7. Foreclosure and Sale of Collateral. Upon the occurrence of any Event of Default, Pledgee may, without notice, except as specified below, at its option, sell all or any part of the Shares, for cash, note or other property upon credit for future delivery or upon such other terms as Pledgee may deem commercially reasonable. Upon such sale, Pledgee, unless prohibited by a provision of any applicable statute, may purchase all or any part of the Shares being sold, free from and discharged of all trusts, claims, rights of redemption and equities of Pledgor. If, at any time when Pledgee shall determine to exercise its rights to sell all or any part of the Shares pursuant to this Section 7, such Shares, or the part thereof to be sold, shall not be effectively registered under the Act as then in effect or any similar statute then in force, subject to the provisions of Section 8 hereof, Pledgee, in its sole and absolute discretion, is hereby expressly authorized to sell such Shares, or any part thereof, by private sale in such manner and under such circumstances as Pledgee may deem necessary or advisable in order that such sale may be effectuated legally without such registration or the Pledgee may undertake, in its sole and absolute discretion, to register the Shares under the Act in order to sell such Shares in a public offering, the costs of such registration to be for the account of the Pledgor.

8. Redemption of Collateral. Notwithstanding any other provision of this Pledge Agreement, upon the occurrence of an Event of Default, Pledgee shall give Pledgor written notice of the time and place of any public sale or of the time on or after which any private sale or other Transfer is to be made at least ten (10) days before the date fixed for any public sale or before the day on or after which any private sale or other Transfer is to be made. Pledgor agrees that, to the extent notice of sale shall be required by law, such ten (10) days' notice shall constitute reasonable notification. This notice shall also specify the aggregate outstanding monetary obligations of the Pledgor to Pledgee at the date of such notice (the "Total Obligation"). At any time during such five-day period, Pledgor shall have the right to redeem the Shares by the payment by certified or bank cashier's check of an amount equal to the Total Obligation.

9. Events of Default. Any breach of or default under the payment provisions of the Note by Pledgee shall be considered an Event of Default for purposes hereof and shall entitle Pledgor to pursue its remedies hereunder and under the Note.

10. Termination and Release or Retention of Shares. This Pledge Agreement shall terminate and all remaining Shares held hereunder shall be released from the pledge under this Pledge Agreement and delivered to Pledgor upon the first to occur of the following events during the term of the Note: (i) the payment of all unpaid principal and accrued interest under the Note, or (ii) the sale by Pledgee of a total of 300,000 shares of Pledgor common stock following the date hereof. If neither such event occurs during the term of the Note, then Pledgee shall retain the balance of the Shares then still held hereunder and not already released under Section 6 above in full satisfaction of the remaining unpaid principal and accrued interest under the Note. In such event, Pledgor agrees to sign and deliver such stock power or other instruments as may be necessary to vest in Pledgee title to such Shares, and Pledgee agrees to cancel the Note and any further obligations Pledgor may have under the Note.

11. Cumulation of Remedies; Waiver of Rights. The remedies provided herein in favor of Pledgee shall not be deemed exclusive but shall be cumulative and shall be in addition to all of the remedies in

favor of Pledgee existing at law or in equity. No delay on the part of Pledgee in exercising any of its options, powers or rights, or the partial or single exercise thereof, shall constitute a waiver thereof.

12. Execution of Endorsements, Assignments, Etc. Upon the occurrence of an Event of Default, Pledgee shall have the right for and in the name, place and stead of Pledgor to execute endorsements, assignments or other instruments of conveyance or transfer with respect to all or any of the Shares and any other shares of the capital stock of Pledgee or other property which is held by Pledgee as collateral security pursuant to this Pledge Agreement.

13. Miscellaneous.

(a) Further Assurances; Changes in Capitalization. Each party hereto agrees to perform any further acts and execute and deliver any documents which may be reasonably necessary to carry out the intent of this Pledge Agreement. The provisions of this Pledge Agreement shall apply to any and all stock or other securities of the Pledgee or any successor or assign of the Pledgee, which may be issued in respect of, in exchange for or in substitution of, the Shares by reason of any split, reverse split, recapitalization, reclassification, combination, merger, consolidation or otherwise, and such Shares or other securities shall be encompassed within the term "Shares" for purposes of this Pledge Agreement and the Pledgee shall have a security interest in all such securities on the same terms set forth in this Pledge Agreement.

(b) Notice. Except as otherwise provided herein, all notices, requests, demands and other communications under this Agreement shall be in writing, and if by fax, shall be deemed to have been validly served, given or delivered when sent, or if by personal delivery or messenger or courier service, or by registered or certified mail, shall be deemed to have been validly served, given or delivered upon actual delivery, at the following addresses, telephone and facsimile numbers (or such other address(es), telephone and facsimile numbers a party may designate for itself by like notice):
