| ·   | The      Imaging      Market |
|--------------------|------------------------------|

| (1)   | A      family of products for driving EL panels to back-light liquid crystal      displays (LCD) in hand-held instruments, such as watches, monochrome      screens and to backlight keypads for cell phones, PDAs, pagers, HPCs, MP3      players, and meters. Supertex is one of the key providers of EL drivers      for cell phones, PDAs, and watches and we have a significant share of this      market, due in no small part to the introduction of several inductorless      EL driver ICs, ideally suited for use in space-constrained applications.      We also offer custom processing services for charge-coupled devices (CCD)      and CMOS imaging devices. Our strategy is to expand the number of channels      from one or two to sixteen for lighting the displays which will challenge      the iPhone display. |

| · | We      have focused our product offerings primarily on niche markets which      leverage our capabilities and in which we believe we have dominance      because we are a technology enabler for our customers.  We      attempt to choose markets which are sizable enough to be worth pursuing      but which are not large enough to attract fierce      competition.  These markets could grow sufficiently to attract      increased competition or else competitors could enter due to happenstance      or downturns elsewhere.  One of our emerging markets is drivers      for LED lighting and backlighting, which is expected to become a large      market for drivers during the next few years and is certain to attract      severe competition. In addition, our niche markets might be more      susceptible to shrinkage than more diverse markets due to their      concentration on a few product offerings. |

| · | We      work with our customers to develop products that they will design into      their systems.  Even if we do achieve a design win, the      customer’s system may never go into production or the production may be      smaller than we had anticipated.  Although we attempt to develop      products which will be useful for multiple customers, we may misjudge the      market and develop a product which maybe useful for only a very few      customers. |
|--------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | We      are dependent upon one fab which we own and operate.  Were this      fab to become unable to meet our needs for causes such as, obsolescence      due to process technology changes, our ability to produce our products      would be adversely affected.  In addition, we could encounter      difficulties in operating our fab after an earthquake or any natural      disaster. |
|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | We      have several competitors that are substantially larger and could bring to      bear substantially more resources than we have in our niche      markets.  We have been able to maintain profitable margins in      part because of our dominance in most of our niche      markets.  Increased competition could cause our margins to      decrease. |
|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | Our      gross margins may fluctuate depending on many factors, including but not      limited to, our product mix, competitive pricing dynamics, product yields,      various manufacturing costs, plant utilization, provisions for excess and      obsolete inventory, and absorption of manufacturing    overhead. |

| · | A      director of and the President and CEO of the Company, Henry Pao, along      with his brother, Frank Pao, and the estate of their father, Yunni Pao,      collectively own approximately 14% of our outstanding      stock.  They have no agreement among themselves to act together      with respect to the Company or their stockholdings.  However,      were they to act in concert, they would be our largest beneficial      shareholder and may have the ability to elect one or more directors,      to direct management, and to delay or prevent a change in      control. |
|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | Our      operations may be interrupted and our business would be harmed in the      event of an earthquake, terrorist act, and other disasters.  Our      principal executive offices, our fab facility, and major suppliers are      located in areas that have been subject to severe      earthquakes.  In the event of an earthquake, we and/or our major      suppliers may be temporarily unable to continue operations and may suffer      significant property damage.  Any such interruption in our      ability or that of our major suppliers to continue operations at our      facilities could delay the development and shipment of our      products.  Like other U.S. companies, our business and operating      results are subject to uncertainties arising out of the economic      consequences of current and potential military actions or additional      terrorist activities and associated political instability, and the impact      of heightened security concerns on domestic and international travel and      commerce.  Such uncertainties could also lead to delays or      cancellations of customer orders, a general decrease in corporate spending      or our inability to effectively market and sell our      products.  Any of these results could substantially harm our      business and results of operations, causing a decrease in our      revenues. |

| · | We      sell a substantial amount of our products internationally. International      sales represents 63%, 70% and 63% and of net sales, for fiscal years 2008,      2007 and 2006, respectively.  We expect our international sales      to continue to account for a significant portion of our total      sales.  We also package and test most of our products      abroad.  Problems with foreign economies, political turmoil,      wars, epidemics, fluctuations in currency exchange rate, increased freight      costs, interruptions in air transportation, and generally longer      receivable collection period could disrupt our business and increase our      operating expenses. |

| · | A      significant portion of our sales are from a small number of customers and      the loss of the one of these customers or failure to collect a receivable      from them could adversely affect our operations and financial      position.    We do not have a long-term      distributorship agreement with any of our distributors. Normal terms and      conditions of sale apply, which include a 60-day notice of cancellation      and charges for work-in-process for cancellations less than 60 days from      shipment.  While we have maintained a good relationship with our      significant customers and distributors, deterioration in that relationship      could materially and adversely affect our business and financial      results. |

| · | We      are dependent upon continued innovation by our engineers.  The      competition for engineers with relevant experience is extremely intense in      the Silicon Valley, where most of our engineers are located.  We      must compete in terms of salary, benefits, and working conditions with      many start-ups which can offer more equity incentives. We established an      IC Design Center in Hong Kong in fiscal 2001 where competition for      qualified engineers is not as intense as that in Silicon      Valley.  However, a majority of our process technology and      product innovation activities remains in our Sunnyvale and San Jose      offices. |

| · | We      operate a fab in San Jose, California at which we use various chemicals      and solvents that are regulated by various environmental      agencies.  We cooperate and work with these agencies to comply      with these regulations.  Should we nonetheless inadvertently      contaminate the soil or ground water, or should the previous operator of      the fab have done so, we may be responsible for significant costs to      remediate the situation. |
|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | We      are dependent upon the continued service of several of our key management      and technical personnel.  The loss of the services of one or      more of our engineers, executive officers and other key personnel or our      inability to recruit replacements for, or to attract, retain and motivate      these individuals would be harmful to our business.  We do not      have long-term employment contracts with our  employees. |
|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | Our      success depends upon our ability to protect our intellectual property,      including patents, trade secrets, and know-how, and to continue our      technological innovation. We cannot assure that the steps we have taken to      protect our intellectual property will be adequate to prevent      misappropriation or that others will not develop competitive technologies      or products.  The failure to obtain necessary licenses or other      rights could cause us to lose market share and harm our      business. |

| · | The      Sarbanes-Oxley Act of 2002 required us to change or supplement some of our      corporate governance and securities disclosure and compliance practices.      The SEC and NASDAQ have revised, and continue to revise their regulations      and listing standards. These developments have increased, and may continue      to increase, our legal compliance and financial reporting costs. These      developments also may make it more difficult and more expensive for us to      obtain director and officer liability insurance, and we may be required to      accept reduced coverage or incur substantially higher costs to obtain      coverage. This, in turn, could make it more difficult for us to attract      and retain qualified members of our board of directors, or qualified      executive officers. |

| ·   | Failure      to comply with present or future laws, rules and regulations of any kind      that govern our business could result in suspension of all or a portion of      production, cessation of all or a portion of operations, or the imposition      of significant administrative, civil, or criminal penalties, any of which      could harm our business. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| · | We      are subject to taxation by domestic and foreign taxing      authorities.  Our business is subject to the application of      multiple, and sometimes, conflicting tax laws and      regulations.  The application of tax laws is subject to legal      and factual interpretation, judgment and uncertainty, and tax laws      themselves are subject to change.  Consequently, taxing      authorities from various jurisdictions may impose tax assessments or      judgments against us that could result in a significant change to earnings      related to prior periods, and or an increase in our effective income tax      rate.    |

| · | Changes      in stock option accounting rules were adopted at the start of our fiscal      2007, which increased our compensation expense and resulted in lower      reported operating results prepared in accordance with generally accepted      accounting principles. The additional expenses resulting from this      pronouncement (SFAS 123R) may negatively impact our future stock price if      we continue to utilize broad based employee stock plans to attract and      retain employees or else, if we cease doing so, could result in a      competitive disadvantage to us in the employee  marketplace. |

| ·   | We      invest our excess cash in marketable securities consisting primarily of      auction rate securities and money market funds. As of the end of fiscal      year 2008, the auction rate securities we owned had a par value of      $100,600,000. In the fourth quarter of 2008, the auction rate securities      market experienced failures. The funds associated with securities that      experienced failed auctions will not be accessible until a successful      auction occurs, a buyer is found outside of the auction process, or the      underlying securities have matured or are recalled by the issuer. Given      the recent disruptions in the credit markets and the fact that the      liquidity for these types of securities remains uncertain, as of March 29,      2008, we have classified all our auction rate securities as a long-term      asset in our Consolidated Balance Sheet, as our ability to liquidate      such securities in the next 12 months is uncertain. We have also recorded      a $4,069,000 temporary decline in fair value for these investments, which      in accordance with SFAS 115, Accounting for Certain Investments in Debt      and Equity Securities, has been recorded in Other Comprehensive Loss. We      believe that we will be able to recover these securities at par value in a      future period, as they are AAA or Aaa rated and, are guaranteed by the      United States Department of Education. However, there is no assurance that      we will be able to settle these bonds and recover the cash, nor if we do      recover the cash, when this may occur. We may have to incur further      impairment if the auctions of our securities continue to fail. If the fair      value of these investments declines permanently or is other-than      temporarily impaired, we would be required to take an impairment charge      which would flow through our income statement as an expense and could      cause us to incur a loss for the relevant fiscal  period. |
