PART I - Financial Information



|Item 1. | Financial Statements
|------- | --------------------

The following condensed
consolidated balance sheet as of December 31, 2005, which has been derived from audited financial statements and the unaudited interim condensed consolidated financial statements, consisting of the condensed consolidated balance sheet as of
March 31, 2006, the condensed consolidated statements of operations for the three month periods ended March 31, 2006 and 2005, and the condensed consolidated statements of cash flows for the three month period ended March 31, 2006 and
2005, have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to those rules and regulations, although the company believes that the disclosures made are adequate to make the information not misleading.

The following condensed balance sheet as of December 31, 2005, which has been derived from audited financial statements does not include all of the
information and footnotes included in the Companys Annual Report on Form 10-K for the year ended December 31, 2005. It is suggested that these condensed financial statements be read in conjunction with the financial statements and the
notes thereto included in the Companys Annual Report on Form 10-K for the year ended December 31, 2005.

The preparation of
financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. In the opinion of management, all adjustments (consisting of normal recurring adjustments)
necessary for a fair presentation for the periods presented have been reflected as required by Regulation S-X, Rule 10-01 in these unaudited statements.

Actual results could differ from those estimates and operating results for the three-month period ended March 31, 2006 and are not necessarily indicative of the results that may be expected for any subsequent
period or for the year ending December 31, 2006.

Note 2  Summary of Significant Accounting Policies

Basis of
Presentation

The condensed consolidated financial statements include the accounts of Maxwell Technologies, Inc. and its subsidiaries.
All significant intercompany transactions and account balances are eliminated in consolidation.

In the opinion of management of the
Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows of
Maxwell Technologies, Inc. for all periods presented. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for any subsequent period or for the
entire year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Companys latest annual report on Form 10-K. Certain information
and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been condensed or omitted.

The preparation of financial statements in conformity with U.S. - GAAP requires management to make estimates and assumptions that affect reported amounts
and related disclosures. Estimates have been prepared on the

basis of the most current information available. These estimates include assessing the collectability of accounts receivable, the usage and recoverability of
inventories and long-lived assets and the incurrence of losses on warranty costs, the fair value of warrants and embedded conversion options related to convertible debentures, vacant leased facilities and other facilities offered for sale. The
markets for most of the Companys products are extremely competitive and are characterized by rapid technological change, new product development, product obsolescence and evolving industry standards. In addition, price competition is intense
and significant price erosion generally occurs over the life of a product. As a result of these issues noted and other factors, actual results could differ from the estimates used by management.

The Companys fiscal quarters end on the last day of the calendar month on March 31, June 30, September 30, and
December 31.

Cash and Cash Equivalents, Investments in Marketable Securities

The Company invests its excess cash in debt instruments of the U.S. Government and its agencies, and in high-quality corporate issuers. All highly liquid
instruments with an original maturity of three months or less from purchase are considered cash equivalents, and those with original maturities greater than three months on the date of purchase are considered investments in marketable securities.
The Companys investments in marketable securities are classified as available-for-sale and are reported at fair value, with unrealized gains and losses included in stockholders equity as a separate component of accumulated other
comprehensive income. Realized gains or losses and other-than-temporary declines in value, if any, on available-for-sale securities are reported in other income or expense as incurred. The Company recognized zero, in net realized gains in the period
ended March 31, 2006 and for the year ended December 31, 2005. The Company uses the specific identification method on sales of investments.

Maturities and gross unrealized gains on investments in marketable securities at March 31, 2006 and December 31, 2005 are as follows (in thousands):

Revenue Recognition

We derive substantially all of our revenue from the sale of manufactured products. Product revenue is recognized, according to the guidelines of SEC Staff Accounting Bulletin Numbers 101 Revenue Recognition in Financial Statements,
and 104 Revenue Recognition, when title passes to the customer at either shipment from our facilities or

receipt at their facility, depending on shipping terms, provided collectability is reasonably assured. This method has been consistently applied from period
to period and there is no right of return. Revenue recognized at the time costs are incurred is calculated on a percentage of completion basis, in accordance with Statement of Position 81-1, Accounting for Performance of Construction-Type and
Certain Production-Type Contracts and is limited by the funding of the prime contractor. In prior years, certain continuing and discontinued segments involved revenues from both long-term and short-term fixed price contracts and cost plus
contracts with the U.S. Government directly or through a prime contractor. Those revenues, including estimated profits, were recognized at the time the costs were incurred and included provisions for any anticipated losses. These contracts are
subject to rate audits and other audits, which could result in the reduction of revenue in excess of estimated provisions. In turn, this could increase losses for the periods in which any such reduction occurs.

Computation of Net Loss per Share

Basic loss per
share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Diluted loss per share is calculated on the basis of the weighted average number of common shares outstanding plus the dilutive effect
of outstanding stock options and restricted stock awards of the Company, assuming their exercise using the treasury stock method.

The following table sets forth the computation of basic and diluted loss per share (in thousands, except per share data):

For the three-month periods ended March 31, 2006 and 2005, incremental equivalent shares
under common stock options of 1,075,601 and 588,345, respectively, were not included in the computation of diluted earnings per share as their impact would have been anti-dilutive. Shares issuable on conversion of convertible debentures of 1,315,790
have also been excluded in the computation of diluted earnings per share as their impact would have been anti-dilutive.

Stock Option Plans

The Company has two active stock-based employee compensation plans as of March 31, 2006, which are described more fully in Note 4. As of
December 31, 2005 the Company had accounted for stock-based employee compensation by the disclosure only provisions of SFAS No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148 Accounting for Stock
Based CompensationTransitions and Disclosure. In accordance with the provisions of SFAS No. 123, the Company applied Accounting Principles Board Opinion No. 25 (APB 25) and related interpretations in accounting for its stock
option plans and accordingly, no compensation expense was

recognized for Employee Stock Purchase Plan ( ESPP) and stock options granted to employees in 2005. The Company recognized $361,000 of compensation expense
for restricted stock awards according to APB No. 25 for the year ended December 31, 2005.

Effective January 1, 2006 the company adopted the
fair value recognition provisions of Financial Accounting Standards Board (FASB) revised Statement of Financial Accounting Standards No. 123 (revised) (SFAS 123R), Share-Based Payment, which establishes accounting for share-based awards
exchanged for employee services and requires companies to expense the estimated grant date fair value of these awards over the requisite employee service period. The Company elected the modified prospective method, which provides for certain changes
to the method for valuing share-based compensation. Under the modified prospective method, prior periods are not revised for comparative purposes. The valuation provisions of SFAS 123R apply to new awards and to awards that are outstanding on the
effective date and subsequently modified or cancelled. Estimated compensation expense for awards outstanding at the effective date will be recognized over the remaining service period using the compensation cost calculated for pro forma disclosure
purposes under SFAS No. 123.

The Companys loss before income taxes for the period ended March 31, 2006 is $936,000 higher than in the same
period ended March 31, 2005. Basic and diluted loss per share for the period ended March 31, 2006 would have been ($0.39) if the Company had not adopted SFAS 123R, compared with the basic and diluted loss per share of ($0.45).

On November 10, 2005, the FASB issued FASB Staff Position No. SFAS 123(R)-3, Transition Election Related to Accounting for Tax Effects of Share-Based
Payment Awards. This guidance provides us with up to one year for our initial adoption of the tax effect of statement 123R. The company is considering its alternatives which include the alternative transition method or the simplified method to
establish the beginning balance of the additional paid-in capital pool (APIC pool) related to the tax effects of employee share-based compensation, which is available to absorb tax deficiencies recognized subsequent to the adoption of SFAS 123R.

Warranty Reserve

We generally provide a warranty to our customers for one to two years in the normal course of business. We accrue for the estimated warranty costs at the time of shipment. The estimated warranty liability is
calculated based on historical warranty costs and the historical time frame within which such costs are paid plus any known warranty exposure.

Note 4  Stock-Based Compensation

On March 31, 2006, the Company has in effect two share-based compensation plans under which incentive stock options, non-qualified stock options and
restricted stock awards have been granted to employees. The compensation cost that has been charged against income for those plans was $936,000 for the three-month period ended March 31, 2006. The compensation cost is included in COS, SG&A
and R&D in the amounts of $57,000, $786,000 and $93,000 respectively.

Employee Stock Options and Employee Stock Purchase Plan (ESPP)

The information for the employee stock options and ESPP is presented for the modified prospective portion of these grants. This allows
the Company to use the share-based compensation accounting outlined in SFAS 123R for the options that were granted and ESPP shares granted after December 31, 2005.

The Companys 2005 Omnibus Equity Incentive Plan (the Incentive Plan), approved by the shareholders, provides for the grant of stock based awards, including incentive stock options, non-qualified
stock options, stock appreciation rights, performance awards, restricted stock, and restricted stock unit awards. This Incentive Plan had

an initial 750,000 shares reserved for issuance with additional shares added to the plan from shares forfeited from the 1995 plan which may increase the
number of shares available to be granted.

In 2004, the Company established the 2004 Employee Stock Purchase Plan (ESPP). The aggregate
number of shares of common stock, which may be purchased under this Plan shall not exceed five hundred thousand (500,000) shares of common stock of the Company. As of March 31, 2006 the company has issued a total of 290,570 shares of
common stock from the current and prior ESPP. The plan permits substantially all employees to purchase common stock through payroll deductions, at 85% of the lower of the trading price of the stock at the beginning or at the end of each six-month
purchase period.

The fair value of each option award granted after January 1, 2006 is estimated on the date of grant using the
Black-Scholes valuation model for estimating the fair value of stock compensation granted, with the following assumptions:



|                                |  |                             |   |  |       |

|Expected dividends              |  |                            |   |  |      |  
|Expected volatility             |  | 62.25                       | % |  | 61.00 | %
|Average risk-free interest rate |  | 4.42                        | % |  | 3.90  | %
|Expected life (in years)        |  | 6.15                        |   |  | 4.00  |  

The dividend yield of zero is based on the fact that we have never paid cash dividends and have no
present intention to pay cash dividends. Expected volatility is based on historical Company stock prices using a mathematical formula to measure the standard deviation of the change in the natural logarithm of our underlying stock price that is
expected over a period of time, commensurate with the option life. This is expressed as an annual percentage rate required by our option-pricing model. The risk-free interest rate is derived from the average zero coupon rate for the option expected
life, which approximates the rate in effect at the time of grant. The expected life calculation for the stock option plan is based on SAB 107 shortcut approach. The assumptions used in Black-Scholes valuation model for the ESPP plan is:
expected dividend of zero, expected volatility 43%, average risk-free interest rate of 4.22% and the option life of .5 years which is based on actual life.

Share-based compensation expense recognized in the Consolidated Statement of Operations for the first quarter of fiscal 2006 is based on awards ultimately expected to vest. SFAS 123R requires forfeitures to be
estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on our historical experience of pre-vesting option cancellations, we have assumed an annualized forfeiture rate
of 7%. The ESPP forfeiture rate is 0% as the number of shares that will be purchased is calculated based on employee contributions made as of March 31, 2006. Under the true-up provisions of SFAS 123R, the Company will record additional expense
if the actual forfeiture rate is lower than we estimated, and will record a recovery of prior expense if the actual forfeiture is higher than we estimated.

The following table summarizes the activity under the employee stock option plan, the ESPP is not
presented because no stock has been issued under the ESPP plan for the period after implementing SFAS 123R. The Company did issue shares for ESPP in the first quarter of 2006 but these shares were recognized under the prior accounting treatment as
they were for the last half of fiscal year 2005. The offering period of the ESPP plan commences on January 1, 2006 and shares will be purchased based on contributions made as of June 30, 2006:

The weighted-average grant date fair value of employee options granted during the period ended
March 31, 2006 was $8.60 per share. The total intrinsic value of options exercised during the period ended March 31, 2006 was $2.5 million. The fair value of the ESPP shares to be issued in July 2006 was calculated using the Black-Scholes
valuation model was $3.93 per share. Total compensation expense recognized for the ESPP for the three moths ended March 31, 2006 was $15,000. The intrinsic value of the shares will be calculated when the shares are purchased on behalf of the
employees on or about June 30, 2006.

As of March 31, 2006 there was $2.4 million of total unrecognized compensation cost related
to nonvested stock option granted under the employee option plan. The cost is expected to be recognized over a weighted average period of 1.43 years. Compensation cost for employee options recognized in the period ended March 31, 2006 was $333,000.

Restricted Stock Awards

Beginning in
2005 the Company awarded Directors and selected senior management restricted stock awards under the Companys 2005 Omnibus Equity Incentive Plan. Vesting of Restricted Stock Awards is contingent upon meeting various departmental, company,
market or performance conditions and typically do not vest before a required one year service period. The restricted stock awards have a contractual life, which is typically ten years. The number of shares available for issuance as restricted stock
awards and employee stock options combined is an initial 750,000 shares with additional shares added from forfeitures from the 1995 Stock Option Plan.

The fair value of each restricted stock award is calculated on the date of grant using the stock price on the date of grant. The fair value of awards with market performance conditions have been determined using a
Monte Carlo calculation. Performance conditions have estimated achievement dates over which compensation expense is recognized. The requisite service period is the greater of the estimated achievement date or the minimum 12-month vesting period.
This requisite service period is determined based on an analysis of all the terms and conditions of each grant. The company uses the requisite service period that is most likely to occur including the likelihood that the restricted stock award will
not be earned. The initial requisite service period may be adjusted for changes in the expected outcomes of the related service or performance conditions with such changes recognized prospectively over the remaining requisite service period.

Share-based compensation expense recognized in the Consolidated Statement of Operations for the first quarter of fiscal 2006 is based on
awards ultimately expected to vest. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on our historical experience of
pre-vesting award cancellations, we have assumed an annualized forfeiture rate for restricted stock awards of 6.7%. Under the true-up provisions of SFAS 123R, the Company will record additional expense if the actual forfeiture rate is lower than we
estimated, and will record a recovery of prior expense if the actual forfeiture is higher than we estimated.

For the year ended
December 31, 2005 the Company had recognized $361,000 of compensation expense for restricted stock awards in according with APB No. 25. The Company was required to calculate the restricted stock award expense based on the market price of
the Companys stock at the end of each reporting period. Under SFAS 123R the company determines the fair value at grant date and expenses that amount over the requisite service period. As prescribed under SFAS 123R the Company has reassessed
each restricted stock award that was active and not earned as of January 1, 2006 and determined appropriate share-based expense treatment under SFAS 123R.

The total grant-date fair value of restricted stock awards granted during the period ended
March 31, 2006 was $1.1 million. No awards vested during the period ended March 31, 2006. As of March 31, 2006 there was $1.7 million of total unrecognized compensation cost related to nonvested restricted stock awards granted under
the plan. The cost is expected to be recognized over a weighted average period of 0.8 years.

Outstanding / Unsettled Option Plans

The Company adopted the provisions of SFAS 123R on January 1, 2006, the first day of the Companys fiscal year, using a modified prospective
method, where compensation cost is recognized beginning with the date of adoption. SFAS 123R is only applicable for new awards and to awards that are outstanding on the effective date and if awards are subsequently modified or cancelled.

The following is a summary of the equity incentive plans under which stock options have been granted prior to the Company adopting SFAS 123R that have
not been modified or cancelled since the adoption:



| |  |  | The 1995 Stock Option Plan under which, as amended, 3,340,000 shares of common stock were reserved for future grant.
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | The Companys 1999 Director Stock Option Plan, under which 75,000 shares were reserved for future grant, was adopted in 1999 and approved by the Companys shareholders in
January 2000.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In December 1999, the Company granted 294,030 non-qualified options to the Companys then new President and Chief Executive Officer, Mr. Eibl, outside of the
Companys other option plans.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In April 2002, in conjunction with the purchase of shares of its I-Bus/Phoenix and Electronic Components Group subsidiaries not already owned, the Company issued options to purchase
approximately 520,000 shares of Maxwell common stock in exchange for options to purchase subsidiary common stock. This issuance of stock options was outside of the Companys option plans.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In November 2002, options to purchase 853,461 shares of common stock with strike prices above $10, previously held by senior management and certain outside directors, were
voluntarily cancelled, in exchange for the future issuance (May 2003) of substitute stock options with a strike price equal to the then-prevailing market price of the common stock.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Options granted under these stock option plans are for the purchase of common stock of the Company at not less than the stocks fair market value at
the date of grant. They generally vest in cumulative annual installments of 2030 percent over a four year period with a contractual term of ten years, while the restricted stock awards vest one year from date of grant and if the requirements
of the award are completed with a typical contractual term of ten years. New shares of common stock will be issued to satisfy stock option exercises and restricted stock grants.

Pro Forma

SFAS 123R requires us to present pro forma information for the comparative period prior to the adoption as if we had accounted for all our employee stock options under the fair value method of the original SFAS 123.
The following table illustrates the effect on net income and earnings per share if we had applied the fair value recognition provisions of SFAS 123 to stock-based employee compensation in the prior-year period (dollars in thousands, except per-share
data):

The amortization of stock compensation under SFAS 123R for the period after its adoption, and
under APB 25 or SFAS 123 (pro forma disclosure) for the period prior to its adoption was done in accordance with FASB Interpretation (FIN) No. 28 (i.e., accelerated method). Total compensation cost of options and restricted stock
granted but not yet vested, as of March 31, 2006, $4.1 million, which is expected to be recognized over the weighted average period of 1.2 years.

Cash received from options exercised under all share-based payment arrangements for the quarter ended March 31, 2006 was $3,140,000. The stock option plans issue new shares to satisfy share option exercises and we expect these plans to
have sufficient shares for all options to be issued in fiscal year 2006.

Note 6  Discontinued Operations

As part of a sale of the Companys defense contracting business in 2001, the Company retained certain leases and lease obligations expiring in 2006.
As of March 31, 2006, the net lease obligations are $61,000 and run through April 2006, which covers the lease payments through the end of the lease.

In September 2002, the Company decided to suspend the operations of its PurePulse Technologies, Inc. subsidiary. PurePulse had been designing and developing systems that generate extremely intense, broad-spectrum,
pulsed light to purify water and inactivate viruses and other pathogens that contaminate vaccines and products sourced from human or animal tissues, such as plasma derivatives, transfusion blood components and biopharmaceuticals. The Company has
preserved its intellectual property and certain other technology assets for a possible future sale of such assets. The carrying value of the assets at December 31, 2005 and March 31, 2006 was zero.

Operating results of the discontinued operations are shown separately, net of tax, in the accompanying consolidated statements of operations. The
businesses included in discontinued operations had no sales in the quarters ended March 31, 2006 and March 31, 2005.

Note 7  Related
Parties

We transacted business with one company considered to be a related party. Montena SA, the former parent company of Montena and
a significant shareholder of Maxwell Technologies, Inc., was the lessor for the Companys headquarters in Rossens, Switzerland. The amount of lease payments paid to Montena SA during the quarters ended March 31, 2006 and 2005 were zero and
$207,000, respectively. In January 2006, Montena SA sold the building to an unrelated third party and all payments for the Rossens property lease in 2006 have been made to that unrelated party.

Note 8  Legal Proceedings

We have been named
as a defendant in a suit filed on March 4, 2004 in the Superior Court of the State of California for the County of San Luis Obispo. This suit, Edmonds vs. I-Bus/Phoenix, Inc., was filed by the plaintiff on his behalf and alleges damages
concerning the repurchase of I-Bus/Phoenix, Inc. shares. While the Companys legal counsel cannot express an opinion on this matter, management believes that any liability of the Company that may arise out of or with respect to this
matter will not materially adversely affect the consolidated financial position, results of operations or cash flows of the Company. The range of possible outcomes for this suit is estimated to be between $0 and $153,000.

Note 9Convertible Debentures

On
December 20, 2005, the Company issued $25 million in aggregate principal amount of senior subordinated convertible debentures due and payable in quarterly installments from December 2007 through December 2009 (the Debentures) and
warrants to purchase 394,737 shares of Maxwell common stock. The net proceeds of the issuance totaled approximately $23.7 million after direct placement costs of approximately $1.3 million. The Debentures are convertible into 1,315,790 shares of
Maxwells common stock at any time at the option of the holder.

Interest is due quarterly, starting on April 1, 2006. The
interest rate is the Federal Funds Rate plus 1.125% per annum. All or a portion of the accrued and unpaid interest may be paid in shares of Maxwells common stock at the Companys option.

##### Table of Contents

At the issuance date, the Debentures were convertible by the holder at any time into common shares at a
price of $19.00 per share subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the conversion price of the Debenture. After eighteen months from the issue date, Maxwell may require that a
specified amount of the principal of the Debentures be converted if certain conditions are satisfied for a period of 20 consecutive trading days.

Maxwell is accounting for the conversion option in the Debentures and the associated warrants as derivative liabilities in accordance with SFAS 133, Accounting for Derivative Instruments and Hedging Activities, EITF 00-19,
Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Companys Own Stock and EITF No. 05-2, The Meaning of Conventional Convertible Debt Instrument in Issue No. 00-19. The
discount attributable to the issuance date aggregate fair value of the conversion options, warrants and issuance costs totaling $9.2 million, is being amortized using the effective interest method over the term of the Debentures. For the three-month
period ended March 31, 2006, $904,000 of the discount and prepaid fees was amortized and included in the Condensed Consolidated Statement of Operations.

The change in fair value on revaluation of debenture conversion rights and warrant liabilities represents the difference between the fair value of the warrants and debenture conversion features at December 31,
2005 and their fair value on March 31, 2006 using the Black-Scholes pricing model. The holders and Maxwells conversion rights and the warrants were adjusted to their respective fair market values at March 31, 2006. The net fair
value of the holders and Maxwells conversion rights at March 31, 2006 were $7.8 million which is included in Convertible debentures and long-term debt on the balance sheet. The effect of the fair market value adjustment
was a $3,500,000 charge, which is recorded as Loss on embedded derivatives and warrants.

The warrants issued in connection
with the issuance of the Debentures had an exercise price of $19.00 at the issuance date, subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the then current exercise price. The warrants are
exercisable at any time through December 20, 2010. No warrants had been exercised as of March 31, 2006.

In the event of any
default or fundamental change as defined in the Debentures, the holder will be entitled to require Maxwell to redeem the Debentures (or any portion thereof) at a price equal to the greater of (i) the applicable redemption premium (ranging from
103%-115%) and (ii) the product of (x) the number of shares in to which the Debenture is convertible using the $19.00 per share conversion price and (y) the closing price of Maxwells common stock on the day preceding the default
or fundamental change.

As long as Debentures are outstanding, the Company is required to maintain an $8.0 million cash balance. This
amount is classified as restricted cash at March 31, 2006 and December 31, 2005.

Note 10  Short-Term and Long-Term Borrowings

Short-term borrowings

Maxwell SA, our European subsidiary, has a 2.0 million Swiss Francs (approximately $1.5 million as of March 31, 2006) credit agreement with a Swiss bank. Borrowings under the credit agreement bear interest at 2.52% with repayment
terms extending beyond one month from the date of funding. Borrowings under the credit agreement are unsecured and as of March 31, 2006 and 2005, the full amount of the credit line was drawn.

Maxwell SA has a 1.0 million Swiss Francs (approximately $766,000 as of March 31, 2006) overdraft credit agreement with a Swiss bank, which
renews annually. Borrowings under the credit agreement bear interest at 5.0%. Borrowings under the credit agreement are unsecured and as of March 31, 2006, none of the overdraft credit line was drawn.

The company had a $3.0 million credit line from a U.S. bank for working capital purposes, subject to a one-year repayment period. The line had not been
used and management decided not to renew the line, which expired on January 31, 2006.

Long-term borrowings

Maxwell SA has a term loan with a maximum draw of 1.15 million Swiss Francs, (approximately $881,000 as of March 31, 2006), for financing specific capital equipment expenditures. Borrowings under the term
loan are secured by the equipment being purchased. This credit agreement bears interest at the Swiss inter-bank borrowing rate plus 2.0%. The term loan can be borrowed in quarterly advances up to the maximum limit and repaid over one to five years.
As of March 31, 2006, approximately $705,000 was outstanding. The weighted average interest rate on the funds borrowed at March 31, 2006 was 4.0%.

Note 11  Defined Benefit Plan

We have a retirement plan for our Swiss subsidiary that is classified as a defined
benefit pension plan. The pension benefit is based on compensation, length of service and credited investment earnings. The plan guarantees both a minimum rate of return as well as minimum annuity purchase rates. The Companys funding policy
with respect to the pension plan is to contribute the amount required by Swiss law, using the required percentage applied to the employees compensation. There is no offset provision based on the obligation level of the fund. In addition, the
employee is required to contribute an identical amount to the pension plan. This plan has a measurement date of December 31. We adopted the provisions of SFAS No. 132R, Employers Disclosures about Pensions and Other Postretirement
Benefits in December 2003. Components of the net periodic benefit cost were as follows (in thousands):

Total employer contributions paid during the three-month periods ended March 31, 2006 and
2005 were $78,000 and $72,000, respectively. Additional employer contributions of approximately $195,000 are expected to be paid during the remainder of fiscal 2006.

Note 12  Contingencies

The Defense Departments auditing agency is auditing a contract
entered into by our Microelectronics group as a subcontractor in 1995 and completed in 1999. The Company has requested a release of liability from the prime contractor. There is no assurance that such a release will be obtained or that the Company
will not incur some liability. While management does not anticipate an unfavorable settlement of these matters, unfavorable results of the audit would result in an adverse impact on the Companys cash flow and statement of operations.

The Company enters into indemnification agreements in the ordinary course of business in which the indemnified party is held harmless and
is reimbursed for losses incurred from claims by third parties. In connection with divestitures of certain assets or businesses, the Company often provides indemnities to the buyer with respect to certain matters including, for example,
environmental liabilities and unidentified liabilities related to periods prior to the disposition. Due to the uncertain nature of the indemnities, the maximum liability cannot be quantified. Liabilities for obligations are recorded where
appropriate and when they are probable and can be reasonably estimated. Historically, the Company has not made significant payments for these obligations.

In 2005, a customer brought to our attention a possible defect in a product that we source from another manufacturer and resell to the customer. We are in the process of investigating this matter, but are not yet able
to determine what, if any, warranty exposure Maxwell may have, and therefore, we have not recorded any warranty

reserve provision.

In March 2006, a customer
sent us a demand letter requesting payment of $535,000 for a tester product initially sold in 2002. The Company believes the request has no merit. We have communicated our position to the customer who has not responded to us as of the date of this
filing.

Executive Summary

We begin Managements Discussion and Analysis of Financial Condition and Results of Operations with an overview of our business and strategic plan. Subsequently, we provide a summary of some of the highlights
from the quarter ended March 31, 2006, followed by a discussion of the different aspects of our business. We then proceed, on page 20, to discuss our results of operations for the quarter ended March 31, 2006 compared with the quarter
ended March 31, 2005. Thereafter, beginning on page 22, we provide an analysis of changes in our balance sheet and cash flows, and discuss our capital requirements and financing activities in the section entitled Liquidity and Capital
Resources. Beginning on page 23, we discuss our critical accounting policies, the impact of inflation on our business and new accounting pronouncements.

Overview

Maxwell Technologies, Inc. is a Delaware corporation originally incorporated in 1965 under the name Maxwell
Laboratories, Inc. In 1996, we changed our name to Maxwell Technologies, Inc. headquartered in San Diego, California. We develop, manufacture and market highly reliable, cost-effective energy storage and power delivery components and systems.
Our products are designed and manufactured to provide failure-free, very low maintenance, performance over the life of the applications into which they are integrated. We believe that by satisfying the stringent requirements of such
high-reliability, high-value applications, our products will be able to command much higher profit margins than commodity products. We focus on the following three discrete lines of high-reliability products:



| |  |  | Ultracapacitors:Our primary focus, ultracapacitors, are energy storage devices that possess a unique combination of high power density, extremely long operational life and
the ability to charge and discharge very rapidly. Our BOOSTCAP® ultracapacitor cells and multi-cell packs and modules provide highly reliable energy storage and power delivery solutions for applications in multiple industries, including transportation, energy, consumer and
industrial electronics and telecommunications.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | High-Voltage Capacitors:Our CONDIS® high-voltage capacitors are extremely robust devices that are designed and manufactured to perform reliably for decades in all climates. These products include grading and coupling
capacitors and capacitive voltage dividers that are used to ensure the safety and reliability of electric utility infrastructure and other applications involving transport, distribution and measurement of high-voltage electrical energy.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Radiation-Mitigated Microelectronic Products:Our radiation-mitigated microelectronic products include high-performance, high-density power modules, memory modules and single
board computers that incorporate our proprietary RADPAK® packaging and shielding technology and novel architectures that enable them to withstand environmental radiation effects and perform reliably in space.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In keeping with this strategic focus on high-value, high-margin product lines, over the past several years we have exited several non-strategic,
low-margin businesses. These actions culminated with the sale of our Winding Equipment product line in December 2003, and the phase-out of our magnetics-based power systems product line, which was completed in the first quarter of 2004. These
actions have enabled us to reduce operating expenses, improve efficiency, increase gross profit margins and intensify our focus on our core high-reliability product lines.

Highlights of the Quarter Ended March 31, 2006

We reported revenue of $12 million and a net
loss for the three-month period ended March 31, 2006 of approximately $7.5 million, or $0.45 per diluted share, versus revenue of $9.8 million and a net loss of $2.2 million, or $0.14 per diluted share, for the three months ended March 31,
2005.

##### Table of Contents

During the three months ended March 31, 2006, we continued to focus on developing strategic
alliances, introducing new products, reducing product costs, and increasing revenue. Some of these efforts are described below:



| |  |  | In January 2006, General Hydrogen Corporation placed a 200,000 unit, three-year, purchase order for BOOSTCAP® ultracapacitors to enhance performance and energy management in its Hydricity® Pack technology with strategic pricing if volume thresholds specified in the purchase
order are met.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In February 2006, Enercon GmbH, one of the worlds leading producers of wind energy systems, designated Maxwell as a preferred supplier, and placed a 1.5 million-unit
purchase order for ultracapacitors for wind turbine blade pitch systems.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In February 2006, Maxwell announced that it would introduce more than 30 BOOSTCAP® ultracapacitor products over the next several months as part of a unique product family strategy featuring new Power and

Results of Operations and Financial Condition Quarter Ended
March 31, 2006 Compared with Quarter Ended March 31, 2005

Total Revenue

Total revenue for the three months ended March 31, 2006 was approximately $12.0 million versus $9.8 million for the three months ended March 31,
2005. High Voltage and Boostcap product lines experienced higher revenue levels in 2006 compared with the same period in 2005 while Microelectronics revenue remained flat. High Voltage revenue grew approximately 40% due to strong demand in Asia.
Boostcap revenue grew approximately 14% due primarily to higher demand for the D Cell product offset in part by lower contract revenue from the USABC contract. We expect continued strong demand for High Voltage and Boostcap products as well as lower
contract revenue in future quarters during 2006. There will be no contract revenue for the Microelectronics product line in the second and third quarters of 2006 due to government funding limitations. We expect the funding limitation to be resolved
by the fourth quarter of 2006 at which time we will catch up revenue in the fourth quarter of 2006 and recognize revenue for work performed in the second, third, and fourth quarters.

##### Table of Contents

Gross Profit

For the three months ended March 31, 2006 and 2005, gross profit was approximately $3.5 million and $2.8 million respectively, which represented 29% of revenue. Included in gross profit for both quarters was the impact of contract
revenue from the USABC and NPOESS contracts. Gross profit from contract revenue was approximately 5% and 10% of the total gross profit percentage for the three months ended March 31, 2006 and 2005, respectively. Also included in cost of sales
for the three months ended March 31, 2006 is $57,000 of stock compensation expense related to our adoption of SFAS 123R.

Excluding
the impact of contract revenue, gross profit improvement was driven primarily by the High Voltage product line. High Voltage revenue volume drove 53% of the gross profit improvement with the remainder driven by price. We recorded reserves of
approximately $337,000 and $572,000 in the first quarter of 2006 and 2005, respectively, for ultracapacitor orders received that were priced below our current product cost. We expect to continue driving down production costs to meet the pricing
requirements of the markets in which we compete. Additional reserves may be required against future orders depending on the degree to which we are able to reduce our product costs at the time orders are placed.

Selling, General & Administrative (SG&A) Expense

Selling, general and administrative (SG&A) expenses were approximately $4.3 million for the three months ended March 31, 2006, compared with $3.3 million for the three months ended March 31, 2005. As a percentage of revenues,
SG&A expenses increased to 36% for the three months ended March 31, 2006 from 34% for the three months ended March 31, 2005. The approximate $1.0 million increase is primarily related to stock compensation expense for restricted stock
and stock option awards of $786,000 recognized in 2006.

Research & Development (R&D) Expense

Research and development (R&D) expenses were approximately $2.2 million for the three months ended March 31, 2006 compared with approximately
$1.8 million for the same period in 2005. As a percentage of revenue, R&D expense was 18% for the three months ended March 31, 2006 and 2005. Also, R&D expense for the three months ended March 31, 2006 includes approximately
$93,000 of stock compensation expense related to our adoption of SFAS 123R. R&D spending continues to be focused on Boostcap product development and Microelectronics single board computer product development.

Provision For Income Taxes

We recorded a provision
for income taxes of $175,000 for the three months ended March 31, 2006 compared with $144,000 for the three months ended March 31, 2005. The tax provisions are the result of our Swiss subsidiary generating profitable results.

The Company is currently evaluating its options with regard to establishing the beginning additional paid-in capital (APIC) pool of tax benefits
related to the adoption of FAS123R. The short-cut method as described in FAS123R-3 is likely to be the method we adopt to establish our beginning APIC pool. We have until the fourth quarter of 2006 to establish the methodology to determine the APIC
pool, which will be utilized against future tax expense related to stock option compensation.

Unremitted earnings of foreign subsidiaries
have been included in the consolidated financial statements without giving effect to the United States taxes that may be payable on distribution to the United States because it is not anticipated such earnings will be remitted to the United States.
If remitted, the additional United States taxes paid would not be material.

Discontinued Operations

In March 2001, we sold our Government Systems business for $20.7 million and recorded a gain of $1.1 million, net of a $2.7 million provision mainly related to ongoing lease obligations. As of March 31, 2006 a
reserve provision of $61,000 remains for the lease obligation, which expires in April 2006.

Liquidity and Capital Resources

Changes in Cash Flow

During the three months ended
March 31, 2006, we used $4.0 million of cash in operating activities, as compared with $333,000 of cash used in operating activities during the same period in 2005. The activity in 2005 included a mispayment from a customer of approximately
$1.7 million, which when excluded results in a use of cash of $2.0 million. The $2.0 million increase in the cash used in operating activities for the three months ended March 31, 2006 compared with the same period of the prior year is a result
of higher inventory and accounts receivable balances supporting higher revenue levels primarily for the High Voltage product line. As revenue levels increase, additional cash will be required for working capital purposes.

Investments in marketable securities increased approximately $7.0 million at March 31, 2006 from approximately $696,000 at December 31, 2005
due to the Company investing proceeds from the convertible debentures issued at the end of 2005. Purchases of property, plant and equipment for $1.9 million during the first quarter of 2006 were related to increasing factory capacity for Boostcap
and High Voltage product lines. We expect to spend approximately $8.4 million during 2006 to increase factory capacity.

Proceeds from the
issuance of stock of $3.1 million during the first quarter of 2006 were a result of employees and former employees exercising stock options. Future stock option exercise activity cannot be predicted with any certainty.

Liquidity

In February 2004, we secured a $3.0
million line of credit from a U.S. bank, which was renewed in 2005, and was available for working capital needs limited by the amount of eligible assets. The line was not used and we decided to not renew the credit line, which expired as of
January 31, 2006. We also have a line of credit for 2 million Swiss Francs (approximately $1.5 million) from a Swiss bank for working capital in Switzerland. The line was fully used as of March 31, 2006 and 2005. We have a 1 million
Swiss Francs (approximately $766,000) overdraft credit agreement with a Swiss bank, none of which was utilized at the end of March 31, 2006 and 2005. We also have a 1.15 million Swiss Francs (approximately $881,000) term loan available from a
Swiss bank for capital equipment purchases. Approximately, $705,000 was outstanding as of March 31, 2006. We had approximately $24.0 million in cash, cash equivalents and restricted cash and approximately $7.7 million in short-term investments
at the end of March 2006. We raised, net of issuance costs, approximately $5.4 million in July 2005 from the sale of shares of common stock. We raised approximately $23.7 million, net of issuance fees, from convertible debentures in December 2005.
In addition, the warrants issued as part of the convertible debt would provide $7.5 million additional liquidity if fully exercised. We believe the liquidity provided by the existing cash and cash equivalents and investments in marketable
securities, and borrowing available under our lines of credit, will provide sufficient capital to fund our capital equipment and working capital requirements and potential operating losses for more than the next 12 months.

Debentures, Short Term and Long Term Borrowings

Convertible
Debentures

On December 20, 2005, the Company issued $25 million in aggregate principal amount of senior subordinated convertible
debentures due and payable in quarterly installments from December 2007 through December 2009 (the Debentures) and warrants to purchase 394,737 shares of Maxwell common stock. The net proceeds of the issuance totaled approximately $23.7
million after direct placement costs of approximately $1.3 million. The Debentures are convertible into 1.3 million shares of Maxwells common stock at any time at the option of the holder.

##### Table of Contents

Interest is due quarterly, starting on April 1, 2006. The interest rate is the Federal Funds Rate
plus 1.125% per annum. All or a portion of the accrued and unpaid interest may be paid in shares of Maxwells common stock at the Companys option.

At the issuance date, the Debentures were convertible by the holder at any time into common shares at a price of $19.00 per share subject to adjustment upon certain events such as the sale of equity securities by
Maxwell at a price below the conversion price of the Debenture. After eighteen months from the issue date, Maxwell may require that a specified amount of the principal of the Debentures be converted if certain conditions are satisfied for a period
of 20 consecutive trading days.

The change in fair value on revaluation of debenture conversion rights and warrant liabilities represents
the difference between the fair value of the warrants and debenture conversion features at December 31, 2005 and their fair value on March 31, 2006 using a Black-Scholes calculation. The fair value of the holders and Maxwells
conversion rights at March 31, 2006 were $7.8 million, which is included in Convertible debentures and long-term debt on the balance sheet. The effect of the fair market value adjustment was a $3.5 million charge, which is recorded
as Loss on embedded derivative liabilities and warrants.

The warrants issued in connection with the issuance of the Debentures
had an exercise price of $19.00 at the issuance date, subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the then current exercise price. The warrants are exercisable at any time through
December 20, 2010. No warrants had been exercised as of March 31, 2006.

As long as Debentures are outstanding, the Company is
required to maintain a cash balance in excess of $8.0 million. This amount is classified as restricted cash at March 31, 2006 and December 31, 2005.

Short-term borrowings

Maxwell SA, our European subsidiary, has a 2.0 million Swiss Francs (approximately $1.5 million
as of March 31, 2006) credit agreement with a Swiss bank. Borrowings under the credit agreement bear interest at 2.52% with repayment terms extending beyond one month from the date of funding. Borrowings under the credit agreement are unsecured
and as of March 31, 2006 and 2005, the full amount of the credit line was drawn.

Maxwell SA, has a 1.0 million Swiss Francs
(approximately $766,000 as of March 31, 2006) overdraft credit agreement with a Swiss bank, which renews annually. Borrowings under the credit agreement bear interest at 5.0%. Borrowings under the credit agreement are unsecured and as of
March 31, 2006, none of the overdraft credit line was drawn.

In February 2004, we secured a $3.0 million credit line from a U.S.
bank. Management decided not to renew the line, which had not been used. The credit line expired on January 31, 2006.

Long-term borrowings

Maxwell, SA has a term loan with a maximum draw of 1.15 million Swiss Francs, (approximately $881,000 as of March 31, 2006),
for financing specific capital equipment expenditures. Borrowings under the term loan are secured by the equipment being purchased. This credit agreement bears interest at the Swiss inter-bank borrowing rate plus 2.0%. The term loan can be borrowed
in quarterly advances up to the maximum limit and repaid over one to five years. As of March 31, 2006, approximately $705,000 was outstanding. The weighted average interest rate on the funds borrowed at March 31, 2006 was 4.0%.

Critical Accounting Policies

This discussion and
analysis of our financial condition and results of operations is based upon our consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America, which we refer to as
U.S.-GAAP. We have used certain assumptions and judgments in the preparation of these financial statements, which assumptions and estimates may potentially affect the reported



23

##### Table of Contents

amounts of assets and liabilities and the disclosure of contingencies as well as reported amounts of revenues and expenses. The following may involve a
higher degree of judgment and complexity and, as such, management assumptions and conclusions in these areas may significantly impact the results of operations of the Company.

Additional information about these critical accounting policies may be found in the Managements Discussion & Analysis of Financial
Condition and Results of Operations section included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2005. There have been no changes to these critical accounting policies subsequent to December 31, 2005,
other than the adoption of SFAS 123R.

Revenue Recognition

We derive substantially all of our revenue from the sale of manufactured products. Product revenue is recognized, according to the guidelines of Staff Accounting Bulletin Numbers 101 Revenue Recognition in
Financial Statements, and 104 Revenue Recognition, when title passes to the customer at either shipment from our facilities or receipt at their facility, depending on shipping terms, provided collectability is reasonably assured. This
method has been consistently applied from period to period and there is no right of return. Revenue recognized at the time costs are incurred is calculated on a percentage of completion basis, in accordance with Statement of Position 81-1,
Accounting for Performance of Construction-Type and Certain Production-Type Contracts and is limited by the funding of the prime contractor. In prior years, certain continuing and discontinued segments involved revenues from both
long-term and short-term fixed price contracts and cost plus contracts with the U.S. Government directly or through a prime contractor. Those revenues, including estimated profits, were recognized at the time the costs were incurred and included
provisions for any anticipated losses. These contracts are subject to rate audits and other audits, which could result in the reduction of revenue in excess of estimated provisions. In turn, this could increase losses for the periods in which any
such reduction occurs.

Stock Compensation

The company has two active share-based payment plans which include options to purchase our common stock by our employees and directors under our stock option plans. Eligible employees can also purchase shares of our common stock at 85% of
the lower of the fair market value at the close of the day prior or the last day of each six-month offering period under our employee stock purchase plans (ESPP). The Company has also awarded Directors and senior management with restricted stock
awards subject to certain market or performance conditions.

As of December 31, 2005 The Company had accounted for these share-based
payment plans using the disclosure only provisions of SFAS No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148 Accounting for Stock Based CompensationTransitions and Disclosure. In accordance
with the provisions of SFAS No. 123, the Company applies Accounting Principles Board Opinion No. 25 and related interpretations in accounting for its stock option plans, and accordingly, no compensation expense has been recognized for
stock options granted to employees and for the ESPP under SFAS No. 123. For the year ended December 31, 2005 the company had recognized $361,000 of compensation expense for restricted stock awards according to APB No. 25. If the
Company had elected to recognize compensation cost based on the fair value method prescribed by SFAS No. 123, the Companys would have recognized $1.6 million as disclosed per the pro forma in the Companys Annual Report on Form 10-k
for the year ended December 31, 2005.

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS 123R,
which replaces SFAS No. 123 (SFAS 123), Accounting for Stock-Based Compensation and supersedes APB Opinion No. 25 (APB 25), Accounting for Stock Issued to Employees. The Company adopted the
provisions of SFAS 123R on January 1, 2006, the first day of the Companys fiscal year, using a modified prospective application, where compensation cost is recognized beginning with the effective date for new awards and to awards that are
outstanding on the effective date and if awards are subsequently modified or cancelled. The change in accounting for the two active share-based payment plans will require the company to determine a value of the awards at the grant date and expense
that amount over the requisite service period. The resulting financial statement impact for the current period, March 31, 2006 was $936,000, which includes $10,000 for non-employees. The change in accounting treatment creates a total
compensation cost related to non-vested awards not yet recognized of $4.1 million with a weighted average period over which they are expected to be recognized of 1.2 years.



24

##### Table of Contents

Estimates of share-based compensation expenses are significant to our financial statements. However,
these expenses are based on an option valuation model and will never result in the payment of cash by the Company. For this reason, and because we do not view share-based compensation as related to our operational performance, we exclude estimated
share-based compensation expense when evaluating the business performance of our operating segment.

Excess and Obsolete Inventory

We value inventories at the lower of cost or market on the first-in, first-out basis. In assessing the ultimate realization of inventories, we make
judgments as to future demand requirements and compare that with current and committed inventory levels. The markets for the Companys products are extremely competitive and are characterized by rapid technological change, new product
development, product obsolescence and evolving industry standards. In addition, price competition is intense and significant price erosion generally occurs over the life of a product. We have recorded significant charges for reserves in recent
periods to reflect changes in market conditions. We believe that future events are subject to change and revisions in estimates may have a significant adverse impact on our balance sheet and statement of operations.

Goodwill

We account for goodwill in accordance with
SFAS No. 142, Goodwill and Other Intangible Assets. This standard requires that goodwill no longer be amortized but is subject to an annual impairment test and when an event occurs or circumstances change such that it is
reasonably possible that an impairment may exist. The first step consists of estimating the fair value of each reporting unit and comparing those estimated fair values with the carrying values of the reporting units, which includes the allocated
goodwill. If the fair value is less than the carrying value, a second step is performed to compute the amount of the impairment by determining an implied fair value of goodwill. The implied fair value of goodwill is the residual fair value derived
by deducting the fair value of a reporting units assets and liabilities from its estimated fair value, which was calculated in step one. The impairment charge represents the excess of the carrying amount of the reporting units goodwill
over the implied fair value of their goodwill. We cannot say with certainty that we may not incur charges for impairment of goodwill in the future if the fair value of Maxwell Technologies and Maxwell SA decrease due to market conditions, revisions
in our assumptions or other unanticipated circumstances. Any impairment charges could adversely affect the results of our operations.

Convertible
Debentures

We account for convertible debentures and warrants in accordance with SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This standard requires the conversion feature of convertible debt be separated from the host contract and presented as a derivative instrument if certain conditions are met. EITF 00-19,
Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Companys Own Stock and EITF 05-2, The Meaning of Conventional Convertible Debt Instrument in Issue No. 00-19were also analyzed to determine whether the debt instrument is to be considered a conventional convertible debt instrument and classified in stockholders equity. The convertible debentures issued on December 20, 2005 were evaluated
and determined not conventional convertible and, therefore, because of certain terms and provisions, including liquidating damages under the associated registration rights agreement, the embedded conversion option was bifurcated and has been
accounted for as a derivative liability instrument. The stock warrants issued in conjunction with the convertible debt on December 20, 2005 were also evaluated and determined to be a derivative instrument and, therefore, classified as a
liability on the balance sheet. The accounting guidance also requires that the conversion feature and warrants be recorded at fair value for each reporting period with changes in fair value recorded in our Statement of Operations.

A Black-Scholes valuation calculation was applied to both of the conversion features and warrants at December 20, 2005, December 31, 2005 and
March 31, 2006. The December 20, 2005 valuation was used for the effective debt discount that these instruments represent. The debt discount is amortized over the four-year life of the debentures using the effective interest method. The
March 31, 2006 and December 31, 2005 valuations were used to record the fair value of these instruments at the end of the reporting period with any difference from prior period



25

##### Table of Contents

calculations reflected in the Statement of Operations. The Companys stock price, which is one input used in the Black-Scholes calculation, has a
significant impact on the calculation. The $5.34 per share increase in the Companys stock price from December 31, 2005 to March 31, 2006 generated a $3.5 million charge on embedded derivative liabilities and warrants in the
Statement of Operations. The volatility of the Companys stock price is likely to generate large swings in the valuations of the conversion features and warrants in future periods.

Pension

The company accounts for the retirement plan for our Swiss subsidiary as a defined benefit
pension plan. This plan is implemented under the terms of the plan as required by Swiss law. In the periods ended March 31, 2006 and 2005 total company contributions were $78,000 and $72,000 respectively while the employee matches the
company-funded amounts. The company anticipates contributing an additional $195,000 to this pension in 2006. The prepaid pension asset at March 31, 2006 and 2005 was $5.1 million and $4.9 million respectively. The Swiss pension is
similar to our U.S. defined contribution plan (401K) in that the basis of the funding requirements does not rest solely on the company. Management believes that the Swiss plan is adequately funded and future payments do not appear
significant based on the current funding status of the plan.

Impact of Inflation

We believe that inflation has not had a material impact on our results of operations for the periods presented. However, there can be no assurance that
future inflation would not have an adverse impact on our operating results and financial condition.

Pending Accounting Pronouncements

In February 2006, the FASB issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments. This statement amends FASB Statements
No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 140,Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities. This statement resolves issues addressed in
Statement 133 Implementation Issue No. D1, Applications of Statement 133 to Beneficial Interests in Securitized Financial Assets. The adoption date does not require any transaction as of March 31, 2006 to comply with this pronouncement.

In March 2006, the FASB issued the Statement of Financial Accounting Standards No. 156, Accounting for Servicing of Financial
Assets, an amendment of FASB Statements No. 140 (SFAS No. 156). SFAS No. 156 requires that servicing assets and servicing liabilities be recognized at fair value, if practicable, when we enter into a servicing agreement and allows
two alternatives, the amortization and fair value measurement methods, as subsequent measurement methods. This accounting standard is effective for all new transactions occurring as of the beginning of fiscal years beginning after September 15,
2006. The effect, if any, of adopting SFAS No. 156 on our financial position and results of operations has not yet been determined.

|Item 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

We face exposure to financial market risks, including adverse movements in foreign currency exchange rates and changes in interest rates. These exposures may change over time and could have a material adverse impact on our financial
results. We have not entered into or invested in any instruments that are subject to market risk, except as follows:

Foreign Currency Risk

Our primary foreign currency exposure is related to our subsidiary in Switzerland. Maxwell SA has Euro and local currency (Swiss
Francs) revenue and operating expenses as well as loans. Changes in these currency exchange rates impact the U.S. dollar amount of revenue, expenses and debt. We do not hedge our currency exposures.

Interest Rate Risk

At March 31, 2006, we had
approximately $2.2 million term debt, of which approximately $529,000 is classified as long-term debt. The carrying value of these borrowings approximates fair value due to the short maturity dates of these instruments. We also had $25 million of
long-term debt for convertible debentures issued on December 20, 2005, of which $24.5 million is classified as long-term debt. We do not anticipate significant interest rate swings in the near future; however, the exchange loss or gain may
significantly affect our balance sheet or statement of operations. A 10% increase in the interest rate on our debt would not have a material effect on our related interest expense.

We invest excess cash in debt instruments of the U.S. Government and its agencies, high-quality corporate issuers and money market accounts. The primary
objective of our investment activities is to preserve principal while maximizing yields without significantly increasing risk. Current policies do not allow the use of interest rate derivative instruments to manage exposure to interest rate changes.
As of March 31, 2006, third parties manage approximately $7.7 million of the investment portfolio under guidelines approved by the Companys Board of Directors. The balance of our cash is invested in money market accounts with banks. A 10%
change in the interest rate on our marketable securities would not have a material effect on our related interest income.



|Item 4. | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and
Procedures

The Company maintains disclosure controls and procedures designed to ensure the information required to be disclosed in
reports filed under the Securities Exchange Act of 1934, as amended (the Exchange Act), is recorded, processed, summarized and reported within the specified time periods. As of the end of the period covered by this report, the
Companys management, including our principal executive officer and principal financial officer, has evaluated the Companys disclosure controls and procedures, as that term is defined in Rule 13a-15(e) of the Exchange Act, and each
concluded that such disclosure controls and procedures are effective.

Changes in Internal Controls over Financial Reporting

There were no changes in the Companys internal control over financial reporting (as defined in Rules 13a-15(f) and 15-d  15(f) under the
Exchange Act) during the last fiscal quarter covered by this report that has materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.

PART II  OTHER INFORMATION



|Item 1. | Legal Proceedings
|------- | -----------------

The Companys subsidiary
I-Bus/Phoenix, Inc. has been named as a defendant in a suit filed on March 4, 2004 in the Superior Court of the State of California for the County of San Luis Obispo. This suit, Edmonds vs. I-Bus/Phoenix, Inc., was filed by the plaintiff
on his behalf and alleges damages concerning the repurchase of I-Bus/Phoenix, Inc. shares. While the Companys legal counsel cannot express an opinion on this matter, management believes that any liability of the Company that may arise out of
or with respect to this matter will have no significant adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

Item 1A. Risk Factors

An investment in our common stock involves a high degree of risk. Our business,
financial condition and results of operations could be seriously harmed if potentially adverse developments, some of which are described below, materialize and cannot be resolved successfully. In any such case, the market price of our common stock
could decline and you may lose all or part of your investment in our common stock.

The risks and uncertainties described below are
not the only ones we face. Additional risks and uncertainties, including those not presently known to us or that we currently deem immaterial, may also result in decreased revenues, increased expenses or other adverse impacts that could result in a
decline in the price of our common stock. You should also refer to the other information set forth in this Quarterly Report and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2005, including our consolidated financial
statements and the related notes.

We have a history of losses and we may not achieve or maintain profitability in the future, which may decrease
the market value of our common stock.

We have incurred net losses in our last seven fiscal years. We cannot assure you that we will
become profitable in the foreseeable future, if ever. Even if we do achieve profitability, we may experience significant fluctuations in our revenues and we may incur net losses from period to period as a result of a number of factors, including but
not limited to the following:



| |  |  | the amounts invested in developing, manufacturing and marketing our products in any period as compared with the volume of sales of those products in the same period;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increasing number of competitors and resulting price competition;
| | - |  | -----------------------------------------------------------------



| |  |  | fluctuations in demand for our products by our OEM customers;
| | - |  | -------------------------------------------------------------



| |  |  | the prices at which we sell our products and services compared with the prices of our competitors and our product costs;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of our product introductions may lag behind those of our competitors;

| |  |  | negative impacts resulting from acquisitions we have made or may make; and
| | - |  | --------------------------------------------------------------------------



| |  |  | future changes in financial accounting standards or practices.
| | - |  | --------------------------------------------------------------

In addition, we incur significant costs developing and marketing products based on new technologies and, in order to increase our market share, we have sold, and may in the future sell, our products at profit margins below those we
ultimately expect to achieve. We have in the past, and may in the future, make a strategic decision to accept certain orders to sell products to a limited number of customers at prices below our manufacturing costs. The impact of the foregoing may
cause our operating results to be below the expectations of public market analysts and investors, which may result in a decrease in the market value of our common stock.

A small number of customers account for a significant portion of our revenues.

We expect that a
small number of customers will continue to account for a large portion of our revenues for the foreseeable future. If our relationships with our large customers were disrupted, we could lose a significant portion of our anticipated revenues. Factors
that could influence our relationships with our customers include:



| |  |  | our ability to sell our products at prices that are competitive with competing suppliers;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | our ability to maintain features and quality standards for our products sufficient to meet the expectations of our customers; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to produce and deliver a sufficient quantity of our products in a timely manner to meet our customers requirements.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

Our large cell ultracapacitors designed for transportation and industrial applications may not gain widespread commercial acceptance, which would adversely impact our
growth opportunities, and our overall business prospects.

We have designed our large cell ultracapacitor products primarily for use in
transportation and industrial applications. Currently, most of the major automotive companies are testing and developing alternative power sources to augment the current 12-volt electrical system or support the power requirements of hybrid drive
systems. We believe our ultracapacitors provide an innovative alternative power solution for both of these applications, and we are currently collaborating technically with several automotive suppliers and auto companies regarding designing our
ultracapacitors into their future products. However, the historic per unit cost of ultracapacitors has prevented ultracapacitors from gaining widespread commercial acceptance. In addition, there are other competing technologies such as advanced
batteries, compressed gas and hydrolytic fluids as well as competing ultracapacitors. We believe that the long-term success of our ultracapacitor products will be determined by our ability to reduce the price of our products and outperform competing
technologies, resulting in our ultracapacitors being widely designed into the next generation of hybrid drive systems and the first generation of up-rated 12 and 42-volt electrical systems. If our ultracapacitor products fail to achieve widespread
commercial acceptance in the next generation of automotive systems, our future revenues and growth opportunities will be adversely impacted and our overall business prospects will be significantly impaired.

We may be unable to produce our large cell ultracapacitors in commercial quantities or reduce the cost of production enough to be commercially viable for widespread
application, which would adversely impact our revenues and growth opportunities, and our overall business prospects.

If we are not able
to produce large quantities of our large cell ultracapacitor products in the near future at a significantly lower per unit cost, our large cell ultracapacitors may not be a commercially viable alternative to competing energy storage and power
delivery solutions. Although we are selling BOOSTCAP®large cell ultracapacitors designed
for transportation and industrial applications, we have only produced these products in limited quantities and at relatively high prices compared with traditional energy storage and power delivery devices.

We have invested significant resources in improving our ultracapacitor cell and multi-cell module designs for higher performance and lower cost, and in
automating internal production and forming an offshore manufacturing alliance in China to scale up our manufacturing capacity to enable us to produce ultracapacitors in quantities sufficient to meet the needs of our potential customers. If we are
unable to continue reducing our cost of production and establishing the capability to produce large quantities of ultracapacitors at a reduced cost, we may not be able to generate commercial acceptance of, and sufficient revenue from, these products
to recover our significant investment in the development and manufacturing scale-up, and our overall business prospects will be significantly impaired.

It may also be difficult for us to solve management, technological, engineering and other problems, which may arise in connection with scaling up our manufacturing processes. These problems may include production
volumes and yields, quality assurance, adequate and timely supply of materials and components and shortages of qualified management and other personnel. In addition, by relying on third parties for offshore manufacturing, we will face risks with
respect to quality assurance, cost and the absence of close engineering support.

We may not be able to develop and market our products successfully,
and thus may not be able to achieve or maintain profitability in the future.

If we are unable to develop and market our products
successfully, we may not achieve or maintain profitability. In recent years, we have introduced many of our products into commercial markets and, upon such introductions, we also must demonstrate our capabilities as a reliable supplier of these
products. Some of our products are alternatives to established products or provide capabilities that do not presently exist in the marketplace. Our products are sold in highly competitive and rapidly changing markets. Our products success is
significantly affected by their cost, technology standards, performance and reliability and end-user preferences. The success of our products also depends on a number of factors, including our ability to:



| |  |  | maintain engineering and marketing staff sufficiently skilled to identify and design new products;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | identify and develop attractive markets for our new products and technologies and accurately anticipate demand;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | develop appropriate sales and distribution channels;
| | - |  | ----------------------------------------------------



| |  |  | develop and manufacture new products that we can sell at competitive prices, with adequate margins;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | deliver products that meet our customers requirements for quality and reliability;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | increase our manufacturing capacity and improve manufacturing efficiency to meet our customer demands while maintaining quality;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | successfully respond to technological changes by improving our existing products and technologies;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | demonstrate that our products have technological and/or economic advantages over competing products;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | successfully respond to competitors that are more experienced, have significantly greater resources and have a larger base of customers; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | secure required raw materials at the prices necessary to manufacture and deliver competitive products.
| | - |  | ------------------------------------------------------------------------------------------------------

If we are unable to secure qualified and adequate sources for our materials, components and sub-assemblies, we may not be able to make our products at competitive costs and we may have difficulty meeting customer
demand, which could damage our relationships with our customers.

Our ability to manufacture products depends in part on our ability to
secure qualified and adequate sources of materials, components and sub-assemblies at prices that enable us to make our products at competitive costs. Some of our suppliers are currently the sole source of one or more items that we need to
manufacture our products.



30

##### Table of Contents

Although we seek to reduce our dependence on sole and limited source suppliers, the partial or complete loss of these sources could have at least a temporary
adverse effect on our business and results of operations and damage customer relationships. Upon occasion, we have experienced difficulty in obtaining timely delivery of supplies from outside suppliers, which has delayed deliveries to our customers.
There can be no assurance that such supply problems will not recur.

Our product lines may be subject to increased competition, and this may limit our
ability to maintain our gross margins. If our competitors develop and commercialize products faster than we do, or commercialize products that are superior to or lower cost than our products, our commercial opportunities may be reduced or
eliminated.

Market acceptance of our products will depend on competitive factors, many of which are beyond our control. Competition in
our markets is intense and has been accentuated by the rapid pace of technological development. Our competitors include large fully integrated electronics companies. We may not be able to develop, fund or invest in one or more of our product lines
to the same degree or as quickly as our competitors do. Many of our competitors have substantially greater research and development capabilities and financial, manufacturing, technological, marketing and sales resources than we do, as well as more
experience in research and development, product testing, manufacturing, marketing and sales. These organizations also compete with us to:



| |  |  | attract parties for collaborations or joint ventures;
| | - |  | -----------------------------------------------------



| |  |  | license proprietary technology that is competitive with our technology; and
| | - |  | ---------------------------------------------------------------------------



| |  |  | attract and hire scientific, engineering and marketing talent.
| | - |  | --------------------------------------------------------------

Our competitors may succeed in developing and commercializing products earlier than we do. Our competitors may also develop products or technologies that are superior to or lower cost than ours, and render our product candidates or
technology obsolete or non-competitive. If we cannot successfully compete with new or existing products, our sales and revenue would suffer and we may not ever become profitable.

If our OEM customers fail to purchase our components or to sell sufficient quantities of their products incorporating our components, or if our OEM
customers sales timing and volume fluctuate, it could prevent us from achieving our sales and market share goals.

Sales to a
relatively small number of OEM customers, as opposed to direct retail sales to end customers, make up the majority of our revenues. For example, one customer, ABB Ltd., accounted for approximately 25% of our revenues in the first quarter of 2006.
Our ability to make sales to OEM customers depends on our ability to compete on price, delivery and quality. The timing and volume of these sales depend upon the sales levels and shipping schedules for the products of our OEM customers. Thus, even
if we develop a successful component, our sales will not increase unless the product into which our component is incorporated is successful. If our OEM customers fail to sell a sufficient quantity of products incorporating our components, or if the
OEM customers sales timing and volume fluctuate, it could prevent us from achieving our sales targets and negatively impact our market share. Our OEM customers typically require a long development and engineering process before incorporating
our products into their systems and products. This period of time is in addition to the time we spend on basic research and product development. As a result, we are vulnerable to changes in technology or end user preferences.

Our opportunity to sell our products to our OEM customers typically occurs at infrequent intervals, depending on when the OEM customer designs a new
product or enhances an existing one. If we are not aware of an OEMs product development schedule, or if we cannot provide components or technologies when they develop their products, we may miss a sales opportunity that may not reappear for
some time.

We may face product liability or warranty claims, either directly or indirectly through our customers, and we have limited experience with
some of our products as to our potential liability.

We offer our customers a warranty for our products. Any product defects could, in
turn, lead to defects in our customers products that incorporate our products. Defects in our products could give rise to warranty claims against



31

##### Table of Contents

us or to liability for damages. Such defects could also lead to liability for consequential damages. Defects in our products could, moreover, impair the
markets acceptance of our products. Any of these events could have a material adverse effect on our business and financial condition. We have limited experience with some of our products in evaluating the potential liability that could be
created by claims under our warranties. If the claims made under such warranties exceed our warranty reserves, our results of operations and financial condition could be materially adversely affected. Additionally, law mandates warranty periods in
some foreign countries. Changes in such laws may affect the adequacy of our warranty reserves.

Unfavorable economic conditions in the U.S. and abroad
may adversely affect our OEM customers and prevent us from achieving sales growth.

Most of our new products are components designed to
be integrated into new products and systems to be introduced to the marketplace by our OEM customers. For example, unfavorable economic conditions in 2003 and 2004 resulted in reduced capital spending on U.S. electric utility infrastructure and
delayed the introduction of certain new products by our OEM customers. A recurrence of such unfavorable economic conditions may adversely affect our ability to market and sell our new products in the future.

A prolonged economic downturn could materially harm our business.

Any negative trends in the general economy, including trends resulting from actual or threatened military action by the United States and threats of terrorist attacks in the United States and abroad, could cause a
decrease in capital spending in many of the markets we serve. In particular, a downward cycle affecting the technology, automotive and industrial, and military and aerospace markets would likely result in a reduction in demand for our products. In
addition, if our customers own markets and financial performance decline, we may not be able to collect outstanding amounts due to us. Any such circumstances could harm our consolidated financial position, results of operations and cash flows.

If we are unable to protect our intellectual property adequately, such as in the Peoples Republic of China (PRC), we could lose our competitive
advantage in the industry segments in which we do business.

Our success depends in part on establishing and protecting our intellectual
property rights. If we are unable to protect our intellectual property adequately, we could lose our competitive advantage in the industry segments in which we do business. Although we protect our intellectual property rights through patents,
trademarks, copyrights, trade secrets and other measures, these steps may not prevent infringement, misappropriation or other misuse by third parties. We have taken steps to protect our intellectual property rights under the laws of certain foreign
countries, but our efforts may not be effective to the extent that foreign laws are not as protective as the laws of the U.S. For example, we have licensed the rights to manufacture and market our patented ultracapacitor technology in the PRC to a
company located in the PRC. Patent and other intellectual property rights receive substantially less protections in the PRC than is available in the United States. In addition, we face the possibility that third parties may reverse
engineer our products to discover how they work and introduce competing products, or that third parties might independently develop products and intellectual property similar to ours.

We have increased our emphasis on protecting our technologies and products through patents. Our success depends on maintaining our patents, adding to
them where appropriate, and developing products and applications without infringing the patent and proprietary rights of others. The following risks, among others, are involved in protecting our patents:



| |  |  | our patents may be circumvented or challenged and held unenforceable or invalid;
| | - |  | --------------------------------------------------------------------------------



| |  |  | our pending or future patent applications may not be issued in a timely manner and may not provide the protections we seek; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | others may claim rights in the patented and other proprietary technology that we own or license.
| | - |  | ------------------------------------------------------------------------------------------------

If our patents are invalidated or if it is determined that we, or the licensor of the patent, do not hold sole rights to the patent, we could lose our
competitive advantage in the industry segments in which we do business.

##### Table of Contents

Competing research and patent activity in our product areas is substantial. Conflicting patent and other
proprietary rights claims may result in disputes or litigation. Although we do not believe that our products or proprietary rights infringe third parties rights, infringement claims could be asserted against us in the future. Also, we may not
be able to stop a third party product from infringing our proprietary rights without litigation. If we are forced to bring such claims or are subject to such claims by others, we could face time-consuming, costly litigation that may result in
product shipment delays, damage payments or injunctions that could prevent us from making, using or selling infringing products. In addition, such litigation could increase our operating expenses and adversely impact our operating results. We may
also be required to enter into royalty or licensing agreements on unfavorable terms as part of a judgment or settlement, which could negatively impact the amount of revenue derived from our products or proprietary rights.

Our reputation and ability to enter into alliances or other strategic arrangements may affect our success.

Our reputation is important to our growth and success. Since we anticipate licensing our technology to others, our reputation may be affected by the
performance of the companies to which we license our technology. Our licenses may grant exclusivity with respect to certain uses or geographic areas. For example, we granted an exclusive license to YEC to manufacture and sell our small cell
BOOSTCAP®products in China, and to sell to other mutually agreed customers elsewhere in
Asia. As a result, we will be wholly dependent on the success of the licensee for success with respect to any exclusive use or geographical area. As with YEC, we anticipate that future alliances may be with foreign partners or entities. As a result,
such future alliances may be subject to the political climate and economies of the foreign countries where such partners reside and operate. We cannot be certain that our alliance partners or other partners will provide us with the support we
anticipate, that such alliances or other relationships will be successful in developing our technology for use with their intended products, or that any alliances or other relationships will be successful in manufacturing and marketing their
products. Any of our international operations will also be subject to certain external business risks such as exchange rate fluctuations, political instability or significant weakening of a local economy in which a foreign entity with which we have
an affiliation operates or is located. Certain provisions of alliance agreements that are for our benefit may be subject to restrictions in foreign laws that limit our ability to enforce such contractual provisions. If these alliances are not
successful our business and prospects could be negatively affected.

We face risks associated with marketing, distribution and sale of our products
internationally and, if we are unable to manage these risks effectively, it could impair our ability to increase sales.

We derive a
significant portion of our revenues from sales to customers located outside the U.S. We expect our international sales to continue to represent a significant and increasing portion of our future revenues. As a result, our business will continue to
be subject to certain risks, such as foreign government regulations, export controls, changes in tax laws, tax treaties, tariffs, freight rates and timely and accurate financial reporting from our international subsidiary. Additionally, as a result
of our extensive international operations and significant revenue generated outside the U.S., the dollar amount of our current and future revenues, expenses and debt may be materially affected by fluctuations in foreign currency exchange rates. If
we are unable to manage these risks effectively, it could impair our ability to increase international sales.

Similarly, assets or
liabilities of our consolidated foreign subsidiary that are not denominated in its functional currency are subject to effects of currency fluctuations, which may affect our reported earnings.

We have substantial operations in Switzerland. Having substantial international operations increases the difficulty of managing our financial reporting
and internal controls and procedures. In addition, to the extent we are unable to respond effectively to political, economic and other conditions in the countries where we operate and do business, our results of operations and financial condition
could be materially adversely affected. Moreover, changes in the mix of income from our foreign subsidiaries, expiration of tax holidays and changes in tax laws and regulations could increase our tax expense.

An ongoing contract audit by the Defense Department could result in charges to our earnings and have a negative effect
on our cash position and we could be subject to additional future audits.

The Defense Departments auditing agency is auditing a
contract entered into in 1995 and completed in 1999 by a company we purchased. We have requested a release of liability from the prime contractor, but there is no assurance that such a release will be obtained and that we will not incur some
liability.

If we are unable to retain key personnel, we could lose our technological and competitive advantage in some product areas and business
segments.

Since many of our products employ emerging technologies, our success depends upon the continued service of our key technical
and senior management personnel. Some of our scientists and engineers are the key developers of our products and technologies and are recognized as leaders in their area of expertise. The loss of such personnel could threaten our technological and
competitive advantage in some product areas and product lines.

Our performance also depends on our ability to identify, hire, train,
retain and motivate qualified personnel, especially key executives, operations staff and highly skilled accountants and engineers. The industries in which we compete are characterized by a high level of employee mobility and aggressive recruiting of
skilled personnel in a highly competitive employment market. All of our employees are at will and thus may terminate their employment with us at any time.

Our business and operations would suffer if we are unable to integrate new key personnel.

We have a
significant number of employees, including senior management, that are new to us. It takes time for new employees to integrate into an organization and work well together as a team. If we are unable to effectively integrate our new
employees, including senior management, into our our organization, our business and operations will be harmed.

Our ability to increase market share and
sales depends on our ability to hire, train and retain qualified marketing and sales personnel.

Because many of our products are new,
we have limited experience marketing and selling them. To sell our products, our marketing and sales personnel must demonstrate the advantages of our products over competing products, and we must be able to demonstrate the value of new technology in
order to sell new products to existing and new customers. The highly technical nature of the products we offer requires that we attract and retain qualified marketing and sales personnel, and we may have difficulty doing that in a highly competitive
employment market. Also, as part of our sales and marketing strategy, we enter into arrangements with distributors and sales representatives to sell our products, and it is possible that our arrangements with outside distributors and sales
representatives may not be successful.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures, redundancy and backup, our internal information technology networking systems are vulnerable to damages
from computer viruses, unauthorized access, energy blackouts, natural disasters, terrorism, war and telecommunication failures. Additionally, from time to time, we install new or upgraded business management systems. To the extent such systems fail
or are not properly implemented, we may experience material disruption to our business, including our ability to report operating results on a timely basis.

Changes in accounting rules for stock-based compensation may adversely affect our operating results, our stock price and our competitiveness in the employee marketplace.

We have a history of using employee stock options and other stock-based compensation to hire, motivate and retain our workforce. In December 2004, the
Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123R, Share-Based Payment, which requires, starting in the first quarter of fiscal year 2006, to measure compensation costs for all
stock-based compensation (including stock options and our employee stock purchase plan) at fair value and to recognize these costs as expenses in our statements of operations. The recognition of these expenses in our statements of operations will
result in lower earnings per share, which could negatively impact our future stock price. In addition, if we reduce our stock-based compensation to minimize the



34



---

##### Table of Contents

recognition of these expenses, our ability to recruit, motivate and retain employees may be impaired, which could put us at a competitive disadvantage in the
employee marketplace.

Compliance with changing regulations of corporate governance and public disclosure may result in additional expenses.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of
2002, new SEC regulations and NASDAQ National Market rules, have created significant additional expenses for public companies. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, our efforts to
comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, significantly increased general and administrative expenses and diversion of management time to such compliance activities. Our recent
efforts to comply with section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations have required significant effort and resources, and resulted in significant cost to us. These efforts and expense are increased because of our
substantial international operations.

Anti-takeover provisions in our certificate of incorporation and bylaws could prevent certain transactions and
could make a takeover more difficult.

Some provisions in our certificate of incorporation and bylaws could make it more difficult for a
third party to acquire control of us, even if such change in control would be beneficial to our stockholders. We have a classified board of directors, which means that our directors are divided into three classes that are elected to three-year terms
on a staggered basis. Since the three-year terms of each class overlap the terms of the other classes of directors, the entire board of directors cannot be replaced in any one year. Furthermore, our certificate of incorporation contains a fair
price provision which may require a potential acquirer to obtain the consent of our board to any business combination involving us.

We have adopted a program under which our stockholders have rights to purchase our stock directly from us at a below-market price if a company or person attempts to buy us without negotiating with the board. This program is intended to
encourage a buyer to negotiate with us, but may have the effect of discouraging offers from possible buyers.

The provisions of our
certificate of incorporation and bylaws could delay, deter or prevent a merger, tender offer, or other business combination or change in control involving us that stockholders might consider to be in their best interests. This includes offers or
attempted takeovers that could result in our stockholders receiving a premium over the market price for their shares of our common stock.

Our common
stock experiences limited trading volume and our stock price has been volatile.

Our common stock is traded on the NASDAQ National
Market. The trading volume of our common stock each day is relatively low. This means that sales or purchases of relatively small blocks of stock can have a significant impact on the price at which our stock is traded. We believe that factors such
as quarterly fluctuations in financial results, announcements of new technologies impacting our products, announcements by competitors or changes in securities analysts recommendations could cause the price of our stock to fluctuate
substantially. These fluctuations, as well as general economic conditions such as recessions or higher interest rates, may adversely affect the market price of our common stock.

We may experience difficulty manufacturing our products, which would prevent us from achieving increased sales and market share.

We may experience difficulty in manufacturing our products in increased quantities, outsourcing the manufacturing of our products and improving our manufacturing processes. If we are unable to improve our
manufacturing processes and manufacture our products in increased quantities, or if the alliance we have formed to outsource the manufacturing of our products is not successful, we may be unable to increase sales and market share for our products
and could also lose existing customers. We have limited experience in manufacturing our products in high volume and, therefore, it may be difficult for us to achieve the following results:



| |  |  | increase the quantity of the new products we manufacture while maintaining quality, especially those products that contain new technologies;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



35



---

##### Table of Contents

| |  |  | reduce our manufacturing costs to a level needed to produce adequate profit margins and avoid losses on committed sales agreements currently priced at below our product costs; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | design and procure additional automated manufacturing equipment.
| | - |  | ----------------------------------------------------------------

It may also be difficult for us to solve management, technological, engineering and other problems, which may arise in connection with our manufacturing processes and in moving substantial manufacturing operations offshore. These problems
may include production volumes and yields, quality assurance, adequate and timely supply of high quality materials and components and shortages of qualified management and other personnel.

If the investors in our December 2005 financing convert their notes or exercise their warrants, it will have a dilutive effect upon our stockholders.

In December 2005 we issued notes and warrants to an institutional investor. Pursuant to the terms of the notes, the holders of such notes may convert
the notes into shares of common stock at any time prior to their maturity at the Conversion Price, subject to adjustment upon specified events, including a price-based weighted average anti-dilution provision, and further subject to adjustment for
stock splits, combinations or similar events specified in the notes. Subject to certain conditions, we can automatically convert the notes into common stock of the Company at the Conversion Price. Unless our shares of common stock trade at or above
a weighted-average price of 115% of the then effective Conversion Price, we will be obligated to repay equal portions of the principal amount outstanding under the notes on a quarterly basis beginning two (2) years after the date of original
issuance, provided that any holder may defer the receipt of any such payment for a period of up to two (2) years. As part of the transaction, we also issued to such investors warrants to purchase up to an additional 394,737 shares of our common
stock at the Conversion Price, subject to anti-dilution provisions similar to the provisions set forth in the notes, and further subject to adjustment for stock splits, combinations or similar events. The warrants are exercisable immediately after
the closing date of the private placement and expire five (5) years from the date of issuance. If the investor converts the notes or exercises the warrants, we will issue shares of our common stock and such issuances will be dilutive to our
stockholders. Because the Conversion Price may be adjusted from time to time in accordance with the provisions of the notes and the warrants, the number of shares that could actually be issued may be greater than the amount described above. In
addition, if such institutional investors or our other stockholders sell substantial amounts of our common stock in the public market during a short period of time, our stock price may decline significantly.

We substantially increased our outstanding indebtedness with the issuance of certain subordinated convertible notes and we may not be able to pay our debt and other
obligations.

In December 2005 we issued notes in the aggregate principal amount of $25 million in a private placement to an
institutional investor. The notes accrue interest at a per annum rate equal to the Federal Funds Rate (as defined in the notes) plus 1.125%, subject to adjustment, with accrued interest payable quarterly. By issuing the notes we increased our
indebtedness substantially. In addition, the holders of the notes have imposed certain restrictive covenants, including limits on our future indebtedness and limits on our ability to incur future liens and make certain restricted payments. Upon a
change of control (as defined in the notes), the holders of the notes will have certain redemption rights. An event of default would occur under the notes for a number of reasons, including our failure to pay when due any principal, interest or late
charges on the notes, certain defaults on our indebtedness, certain events of bankruptcy and our breach or failure to perform certain representations and obligations under the notes. Upon the occurrence of an event of default, our obligations under
the notes may become due and payable in accordance with the terms thereof.

As a result, the issuance of the notes may or will:



| |  |  | make it more difficult for us to obtain any necessary financing in the future for working capital, capital expenditures or other purposes;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make it more difficult for us to be acquired;
| | - |  | ---------------------------------------------

##### Table of Contents

| |  |  | require us to dedicate a substantial portion of our cash flow from operations and other capital resources to debt service;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | limit our flexibility in planning for, or reacting to, changes in our business; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | make us more vulnerable in the event of a downturn in our business or industry conditions.
| | - |  | ------------------------------------------------------------------------------------------

If we are unable to satisfy our payment obligations under the notes or otherwise are obliged to repay the notes prior to the due date, we could default
on such notes, in which case our available cash could be depleted, perhaps seriously, and our ability to fund operations could be materially harmed.

Our credit agreements contain various restrictions and covenants that limit managements discretion in the operation of our business and could limit our ability to grow and compete.

The credit agreements governing our bank credit facilities contain various provisions that limit our ability to:



| |  |  | incur additional debt;
| | - |  | ----------------------



| |  |  | make loans, pay dividends and make other distributions;
| | - |  | -------------------------------------------------------



| |  |  | create certain liens on, or sell, our assets;
| | - |  | ---------------------------------------------



| |  |  | merge or consolidate with another corporation or entity, or enter into other transactions outside the ordinary course of business; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make certain changes in our capital structure.
| | - |  | ----------------------------------------------

These
provisions restrict managements ability to operate our business in accordance with managements discretion and could limit our ability to grow and compete. Our credit agreements also require us to maintain our compliance with certain
financial covenants and ratios. If we fail to comply with any of such financial covenants or ratios, or otherwise default under our credit agreements, the lenders under such agreements could:



| |  |  | accelerate and declare all amounts borrowed to be immediately due and payable, together with accrued and unpaid interest;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | terminate their commitments, if any, to make further extensions of credit to us and/or attempt to secure collateral.
| | - |  | --------------------------------------------------------------------------------------------------------------------

In the event that amounts due under our credit agreements are declared immediately payable, we may not have, or be able to obtain, sufficient funds to
make such accelerated payments.

We may not be able to obtain sufficient capital to meet potential customer demand or corporate needs, which could
require us to change our business strategy and result in decreased profitability and a loss of customers.

We believe that in the future
we will need a substantial amount of additional capital for a number of purposes, including the following:



| |  |  | to meet potential production volumes for our product lines, particularly our ultracapacitors, which require high-speed automated production lines to achieve targeted customer volume
and price requirements;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In December 2005, we raised approximately $23.7 million (net of offering expenses) through a private placement of convertible debentures and warrants to purchase shares of our common stock. In July 2005, we raised
approximately $5.4 million (net of offering expenses) through the sale of our common stock pursuant to a shelf registration statement on Form S-3. However there can be no assurance that additional financing will be available to us on acceptable
terms or at all. If adequate funds are not available when needed, we may be required to change or delay our planned growth, which could result in decreased revenues, profits and a loss of customers. The issuance of additional shares will result in
dilution of our current stockholders. Further, if additional financing is accomplished by the issuance of debt, the service cost, or interest, will reduce net income or increase net losses and may also require the issuance of additional warrants to
purchase shares of common stock.

The issuance of shares of our common stock could result in the loss of our ability to use our net operating losses.

As of December 31, 2005, we had approximately $140.4 million of federal tax and state tax net operating loss carry forwards.
Realization of any benefit from our tax net operating losses is dependent on: 1) our ability to generate future taxable income and 2) the absence of certain future ownership changes of our common stock. An ownership change,
as defined in the applicable federal income tax rules, would place significant limitations, on an annual basis, on the use of such net operating losses to offset any future taxable income we may generate. Such limitations, in conjunction with the
net operating loss expiration provisions, could effectively eliminate our ability to use a substantial portion of our net operating losses to offset any future taxable income. The issuance of shares of our commons stock could cause an
ownership change. Such transactions include the issuance of shares of common stock upon future conversion or exercise of outstanding options, warrants and convertible preferred stock.
