ITEM 1. BUSINESS

GENERAL

We use a proprietary vertical gradient freeze, commonly referred to as "VGF," technique to produce high-performance compound semiconductor substrates which are used in a variety of electronic and opto-electronic applications such as wireless and fiber optic telecommunications, lasers, LEDs, satellite solar cells and consumer electronics. We primarily manufacture and sell gallium arsenide, called GaAs, substrates. Sales of GaAs substrates accounted for approximately 81.8% of our product revenues in 1998. We also manufacture and sell indium phosphide, or InP, and germanium, or Ge, substrates and are currently developing other high-performance compound substrates including gallium phosphide, or GaP, and gallium nitride, or GaN. Our customers include:

- EMCORE,

- Hewlett Packard,

- Motorola,

- NEC,

- Nortel,

- Siemens,

- Sony,

- Spectrolab, and

- TRW.

BACKGROUND

Recent advances in communications and information technologies have created a growing need for power efficient, high-performance electronic systems that operate at very high frequencies, have increased computational and display capabilities, and can be produced cost-effectively in commercial volumes. In the past, electronic systems manufacturers have relied on advances in silicon semiconductor technology to meet many of these demands. Silicon-based semiconductor devices, however, have performance limitations in power efficient, high-performance electronic applications. In addition, silicon-based semiconductor devices currently do not possess the electrical properties necessary to be used effectively in most opto-electronic applications such as LEDs and lasers.

As a result of the limitations of silicon, semiconductor device manufacturers are increasingly utilizing alternative substrates to improve the performance of semiconductor devices or to enable new applications. These alternative substrates may be composed of a single element, such as Ge, or multiple elements which may include:

- gallium,

- aluminum,

- indium,

1

- arsenic,

- phosphorus, and

- nitrogen.

Substrates that consist of more than one element are commonly referred to as "compound substrates" and include GaAs, InP, GaP and GaN. GaAs is currently the most widely used compound substrate. In comparison to silicon, compound substrates have electrical properties that allow semiconductor devices to operate at much higher speeds or at the same speed with lower power consumption. For example, electrons move up to five times faster in GaAs than in silicon. Compound substrates also have better opto-electronic characteristics than silicon which allow them to convert energy into light and lasers, or to detect light and convert light into electrical energy. The GaAs substrate market is divided into two segments, semi-insulating and semi-conducting.

Semi-insulating GaAs substrates. The market for semi-insulating GaAs substrates is the fastest growing segment of the GaAs market. According to projections by Dataquest, IDC and Strategies Unlimited, the market for semi-insulating GaAs substrates was estimated at $125 million in 1998 and is expected to grow to approximately $400 million by the year 2002. This growth is being driven by increasing demand for semi-insulating GaAs substrates in a variety of power-efficient, high-performance applications, including cellular phones, radars, satellite communication systems and direct broadcast systems.

Manufacturers integrate semi-insulating GaAs substrates into devices using either an ion implantation or epitaxial process. Ion implantation is the process of implanting ions directly into the semi-insulating GaAs substrate to modify the electrical parameters of the substrate so that it can be used to manufacture many of today's high-performance electronic devices. This process requires the electrical parameters of the substrate to be as uniform as possible. Epitaxy, a more recently developed process, involves the growth of layers of other materials onto the semi-insulating GaAs substrate. While generally more expensive than the ion implantation process, the epitaxial process enables devices to achieve even greater performance advantages. The epitaxial process requires that the GaAs substrate have an extremely smooth surface, few physical imperfections, uniform electrical properties and low dislocation density, which is a measurement of the crystalline perfection of the substrate material.

Traditionally, crystals for semi-insulating GaAs substrates for the ion implantation and epitaxy markets have been grown using the liquid-encapsulated czochralski, or LEC technique. The LEC technique requires a high temperature gradient in the manufacturing process. Because the temperature gradient in the LEC technique is high, the resulting crystals have a relatively high dislocation density which weakens a crystal's physical structure and increases the risk of breakage of the GaAs substrate during device manufacturing. In addition, as semi-insulating GaAs substrates continue to grow in size to support increasingly complex devices, the manufacturing challenges facing the LEC technique increase.

Semi-conducting GaAs substrates. We believe that the market for semi-conducting GaAs substrates, based on 1998 market data and annual growth rates projected by Dataquest, IDC and Strategies Unlimited, was approximately $90 million in 1998 and we expect that the market will continue to grow. The market for semi-conducting GaAs substrates is being driven by increasing demand for a number of opto-electronic applications such as LEDs and lasers, which are incorporated into a variety of products including:

- traffic lights,

- digital versatile discs, more commonly known as DVD players,

- CD players,

- CD-ROMs,

- laser printers,

- automobile lights and

- electronic displays.

2

In contrast to semi-insulating GaAs substrates which undergo either an ion implantation or epitaxial process, semi-conducting GaAs substrates only undergo an epitaxial process. As with semi-insulating GaAs substrates, semi-conducting GaAs substrates that undergo the epitaxial process must have a smooth surface, few physical imperfections, uniform electrical properties and a low dislocation density. The traditional method of growing crystals for producing semi-conducting GaAs substrates is the Horizontal Bridgeman, or HB, technique. With the HB technique, the crystal is grown in a semi-cylindrical container which results in a semi-circular, or D-shaped, substrate. In order to produce a round semi-conducting GaAs substrate, the HB technique requires that the D-shaped substrate be cut into a circle, resulting in a large amount of discarded substrate. In addition, crystals grown using the HB technique generally have a relatively high dislocation density and less uniform electrical properties. These and other inherent technical difficulties limit the ability of the HB technique to be used to cost-effectively produce high-quality substrates greater than three inches in diameter.

Other high-performance substrates. We believe there are significant growth opportunities in manufacturing other high-performance substrates. For example, we believe that the markets for InP and GaP substrates, based on 1997 market data and annual growth rates projected by Dataquest, IDC and Strategies Unlimited, were an aggregate of approximately $150 million in 1998 and we expect that these markets will continue to grow. Semi-insulating InP substrates are used in power-efficient, high-performance electronic applications such as wireless and high-bandwidth communications and semi-conducting InP substrates are used in such applications as fiber optic communications and lasers. GaP substrates are used by manufacturers of LEDs. The traditional method for growing crystals for InP and GaP substrates has been the LEC, technique. In addition to compound substrates, the market for the element Ge is developing in response to the growing demand for solar cells in satellite communications. We believe that the market for Ge substrates used to manufacture solar cells was approximately $60 million in 1998 and we expect that the market will continue to grow. This application requires the use of Ge substrates which must be manufactured with few defects and minimal breakage. We believe the further development of these markets depends on the ability of suppliers to cost-effectively manufacture power-efficient, high-performance compound and single-element substrates.

THE AXT SOLUTION

We use a proprietary VGF technique to produce high-performance GaAs and other substrates for use in a variety of electronic and opto-electronic applications. We believe that our VGF technique, which we have developed over the past 12 years, provides certain significant advantages over traditional manufacturing methods for growing crystals used in the production of semi-insulating and semi-conducting GaAs substrates. We believe that we are currently the only high-volume supplier of GaAs substrates manufactured by using the VGF technique and are positioned to become a leading manufacturer and supplier of other compound and Ge substrates.

In the GaAs substrate market, crystals grown using our proprietary VGF technique have a dislocation density that is significantly lower than crystals grown using either the LEC or HB technique. As a result, we believe our GaAs substrates have greater mechanical strength which often results in reduced breakage during the ion implantation and epitaxial growth processes. Furthermore, we believe the low dislocation density of our semi-insulating and semi-conducting GaAs substrates translates into fewer defects in the materials layered onto the substrate during the epitaxy process. In addition, semi-insulating GaAs substrates produced using our VGF technique have more uniform electrical properties than LEC-produced GaAs substrates, which is important for the ion implantation process. In the semi-conducting GaAs substrate market, VGF-grown crystals, unlike those grown using the traditional HB technique, can be processed into round substrates with minimal wasted material. Using our VGF technique, we have been able to produce GaAs substrates as large as six inches in diameter.

In addition to the GaAs substrate market, we believe we can leverage our expertise in the VGF technique to manufacture and produce commercial volumes of other compound and single-element substrates. For example, in 1998, we shipped Ge and InP substrates to customers and qualified our wafers with many more potential customers.

STRATEGY

Our strategy is to be the leading developer and supplier of high-performance GaAs substrates for both the semi-insulating and semi-conducting markets, and to continue to expand into the development and supply of other substrates. The key elements of our strategy include:

Advance VGF technology leadership. We pioneered the commercial use of the VGF technique and have continued to develop and enhance our technology over the course of 12 years through substantial investments in research and development. Our efforts have led to significant improvements in the dislocation density, mechanical strength and uniformity of the electrical properties of GaAs substrates. We believe that our experience and expertise in VGF technology provides us with a competitive advantage over more recent market entrants who are utilizing variations of the VGF technology. We intend to continue to advance our VGF technology through continued investment in research and development and participation in certain government sponsored research programs.

Extend leadership in GaAs market. We are currently one of the largest suppliers of GaAs substrates worldwide. Historically, we have been a leading supplier of GaAs substrates in the epitaxy segment of the semi-insulating market and in the semi-conducting market for GaAs substrates for lasers. We intend to increase our share of these markets by continuing to provide high-quality, price-competitive substrates. In addition, in the semi-insulating GaAs substrate market, we intend to leverage our demonstrated success in the epitaxy segment to further penetrate the ion implantation segment. In the semi-conducting GaAs substrate market, we also intend to capitalize on our leadership to further penetrate the high-volume, cost-sensitive LED market.

Leverage VGF technology to manufacture additional substrates. We believe our VGF technology is a platform which we can leverage to rapidly develop and cost-effectively manufacture additional high-quality compound substrates for emerging applications in markets such as wireless and fiber optic communications. For example, we recently began shipping InP and Ge substrates developed using our VGF technique to customers. Unlike the more traditional methods of growing crystals, we can use our VGF technology to grow the crystals for these other substrates without having to make a significant investment in new capital equipment.

Increase manufacturing capacity to target high-volume markets. We increased our manufacturing capacity by approximately 30,000 square feet in the fourth quarter of 1998. In addition, in June 1998, we have purchased an additional 58,000 square foot facility in Fremont, California. In January 1999, we announced we had received a business license for operations in Beijing, China and had purchased a 30,000 square foot facility in a major tax-free industrial park in Beijing. These new facilities provide us with additional manufacturing capacity. We believe that this increased manufacturing capacity will enable us to further lower unit production costs and provide our high-performance substrates at competitive prices for high-volume markets such as LEDs.

Leverage existing customer relationships. We currently sell our GaAs substrates to over 200 customers, including:

- EMCORE,

- Hewlett Packard,

- Motorola,

- NEC,

- Nortel,

- Siemens,

- Sony,

- Spectrolab, and

- TRW.

4

We believe our past success in providing high-quality GaAs substrates to these customers will provide us with a competitive advantage in supplying them additional substrates as their needs develop. For example, we recently began shipments of InP substrates to TRW, which currently purchases a significant portion of its GaAs substrates from us. In addition, we intend to establish alliances and joint development arrangements with customers to develop new products, increase manufacturing efficiencies and more effectively serve our customers' needs.

We have historically entered into significant contracts with a number of government agencies and customers for the development of certain products. For more information regarding our development efforts, see " Research and Development."

In the twelve months ended December 31, 1998, one customer accounted for 13.7% of our total revenues. No customer accounted for more than 10.0% of our total revenues in 1996 and 1997. In 1996, 1997 and 1998, our five largest customers accounted for 35.5%, 34.9% and 39.5%, respectively, of our total revenues. Generally, we do not have long-term or other non-cancelable commitments from our customers and usually sell products pursuant to customer purchase orders. The loss of any major customer could have a material adverse effect on our business and operating results.

TECHNOLOGY

AXT's VGF technique. Our proprietary VGF technique produces high-quality crystals from which we produce high-performance compound and single-element substrates for use in a variety of electronic and opto-electronic applications.

Our VGF technique is designed to control the crystal-growth process with minimal temperature variation. Unlike traditional techniques, our VGF technique places the hot GaAs melt above the cool crystal, thereby reducing the turbulence of the GaAs melt which results when the melt and crystal are inverted. The temperature gradient between the melt and the crystal in the VGF technique is significantly lower than in traditional techniques. These aspects of the VGF technique enable us to grow crystals that have a relatively low dislocation density and high uniformity. One of the benefits of these characteristics is that the crystal, and the substrate into which the crystal is manufactured, are mechanically strong. The mechanical strength often results in substrates with lower breakage rates during a customer's manufacturing process.

Under the VGF technique, the GaAs melt and growing crystal are contained in a closed chamber. A number of benefits result from the use of this closed system. Because the VGF system is sealed and the crystal growth is isolated, both semi-insulating and semi-conducting crystals can be grown in the same system without the time consuming and expensive process of completely reconfiguring the system. The closed system isolates the crystal from the outside environment during growth and significantly reduces potential contamination of the crystal by impurities. The closed system also allows for more precise control of the gallium-to-arsenic ratio which results in better consistency and uniformity of the crystals. Therefore, crystals grown using the VGF technique are consistently of a high quality. In addition, the use of cylindrical crucibles, which are sized to

5

meet a customer's requirements, enables us to produce circular substrates with a minimum amount of discarded material.

The VGF technique is highly automated and the temperature gradient is controlled electronically rather than by physically moving the crystal or furnace. As a result, there is no physical movement to disturb the sensitive crystal. The entire crystal growth process is run under computer control with minimal operator intervention. A single operator can supervise the control of many VGF furnaces which results in significant cost savings.

We believe the VGF technology is a platform which we can leverage to rapidly develop and cost-effectively manufacture additional high-quality substrates. Unlike the more traditional methods of growing crystals, we can use the VGF technology to grow crystals from these other substrates without having to make a significant investment in new capital equipment. For example, we use the proprietary VGF technique to manufacture InP and Ge substrates.

VGF compared to traditional techniques for producing GaAs substrates. We believe our proprietary VGF technique provides significant advantages over the traditional crystal growth techniques. The LEC technique is the traditional method for producing semi-insulating GaAs substrates. Unlike the VGF technique, the LEC technique is designed so that the hotter GaAs melt is located beneath the cooler crystal, which results in greater turbulence in the melt. The LEC technique requires a temperature gradient between the GaAs melt and the cool crystal which is approximately 50 to 200 times higher than the temperature gradient of the VGF technique. The turbulence and the high temperature gradient cause LEC-grown crystals to have a higher dislocation density than VGF-grown crystals. This characteristic results in a higher rate of breakage of the LEC-developed substrate during the device manufacturing process. In addition, the LEC technique is essentially an open process whereby the melt and growing crystal are exposed to the environment for the entire duration of the crystal growth process. This exposure results in greater propensity for impurity contamination as well as difficulty in controlling the ratio of gallium to arsenic. Because the crystal is not contained in a crucible, fluctuations in temperature cause the diameter of the crystal to vary. Thus, to ensure proper size with the LEC technique, the crystal must be grown significantly larger than the desired size of the resulting substrate. During the LEC process, the crystal is grown by dipping a seed crystal through molten boric oxide into a melt and slowly pulling the seed up into the cool zone above the boric oxide where the crystal hardens. As the GaAs melt is consumed, the crucible containing the remaining liquid must be raised in coordination with the pulling of the crystal. These moving parts and the relative complexity of the system result in higher maintenance costs. Unlike the VGF technique, the LEC technique uses large, complex electro-mechanical systems that are expensive to acquire and require highly skilled personnel to operate.

The HB technique is the traditional method for producing semi-conducting GaAs substrates. The HB technique holds the GaAs melt in a semi-cylindrical "boat." Because of the semi-cylindrical shape of the boat, semi-conducting GaAs crystals grown using the HB technique have a semi-circular cross-section. As a result of this semi-circular shape, more crystal material must be discarded to cut the crystal ingot into a cylindrical shape from which round substrates can be produced. Furthermore, crystals grown using the HB technique have a higher dislocation density than VGF-grown crystals. These and other inherent technical difficulties limit the ability of the HB technique to be used to cost-effectively produce high-quality substrates greater than three inches in diameter. Since the HB technique uses a quartz crucible during the growth process which can contaminate the GaAs melt with silicon impurities, the HB technique is also unsuitable for making semi-insulating GaAs substrates.

PRODUCTS

We currently sell the compound substrates GaAs and InP, and the single-element substrate Ge. We supply various sizes of substrates in 2, 3, 4, and 6 square inches according to our customers' specifications and work closely with our customers to ensure that we manufacture substrates to each customer's particular specifications.

MANUFACTURING

Our manufacturing operations, which include crystal growth, slicing, testing, edge grinding, polishing, inspecting and packaging the substrates for shipment, are located at our headquarters in Fremont, California. Our Fremont facilities are ISO 9002 certified. Many of our manufacturing operations are computer monitored or controlled, enhancing reliability and yield.

We depend on a single or limited number of suppliers for certain critical materials, including gallium, for use in the production of substrates. We generally purchase these materials through standard purchase orders and not pursuant to long-term supply contracts. We seek to maintain sufficient levels of inventory for certain materials to guard against interruptions in supply and to meet our near term needs. To date, we have been able to obtain sufficient supplies of materials in a timely manner. However, a stoppage or delay in supply, receipt of defective or contaminated materials, or increases in the pricing of such raw materials could materially adversely affect our operating results.

In the third quarter of 1998, we completed the expansion of our approximately 50,000 square feet facility located in Fremont, California by approximately 30,000 square feet to meet anticipated production needs through 1999. Because we currently perform all steps in our manufacturing process at our Fremont facility, any interruption resulting from earthquake, fire, equipment failures or other causes would have a material adverse effect on our results of operations. For more information regarding the risks relating to our manufacturing process and our new facility, see "Factors Affecting Future Results -- If we do not achieve acceptable yields of crystals and the successful and timely production of substrates, the shipment of our products would be delayed and our business adversely affected." and "Factors Affecting Future Results -- We are subject to additional risks as a result of the recent completion of a new manufacturing facility," respectively.

Additionally, in connection with further expanding our manufacturing capacity, we purchased an additional 58,000 square foot facility in Fremont, California and a 30,000 square foot facility in Beijing, China in 1998.

SALES AND MARKETING

We sell our products worldwide through our direct sales force as well as through independent international sales representatives. Our direct sales force consists of highly trained, technically sophisticated sales engineers who are knowledgeable in the manufacturing and use of compound and single-element substrates. Our direct sales force operates out of our corporate office in Fremont, California and our Japanese subsidiary. Our sales engineers work with customers during all stages of the substrate manufacturing process, from developing the precise composition of the substrate through manufacturing and processing the substrate

7

to the customer's exact specifications. We believe that maintaining a close relationship with customers and providing customers with ongoing technical support improves customer satisfaction and will provide us with a competitive advantage in selling other substrates to our customers.

International sales, excluding Canada, as a percentage of total revenues in 1996, 1997 and 1998 were 35.0%, 34.1% and 28.8%, respectively. In addition to our direct sales force in Japan, we have independent sales representatives in France, Japan, South Korea, Taiwan and the United Kingdom. Except for sales by our Japanese subsidiary, which are denominated in yen, we receive all payments for products in U.S. dollars.

In order to raise market awareness of our products, we advertise in trade publications, distribute promotional materials, publish technical articles, conduct marketing programs and participate in industry trade shows and conferences. For more information regarding the risks relating to our international operations, see "Factors Affecting Future Results -- We derive a significant portion of our revenues from international sales and our ability to sustain and increase our international sales involve significant risks".

RESEARCH AND DEVELOPMENT

Our research and development efforts are focused on developing new substrates, improving the performance of existing products and processes, and reducing costs in the manufacturing process. We have assembled a multi-disciplinary team of highly skilled scientists, engineers and technicians to meet our research and development objectives. Among other projects, we have research and development projects involving the development of GaN and high purity GaAs epitaxy substrates.

Our research and development expenses in 1996, 1997 and 1998 were $592,000, $1.3 million and $2.5 million, respectively. In addition to internally funded research and development, we have also funded a significant portion of our research and development efforts through contracts with the U.S. government and customer funded research projects. In 1996, 1997 and 1998, we received $2.0 million, $2.3 million and $1.8 million, respectively, from U.S. government agencies and customer funded research contracts. Under our contracts, we retain rights to the VGF and wafer fabrication technology which we develop. The U.S. government retains rights to utilize the technologies we develop for government purposes only.

Our total research and development costs, including both contract funded and internally funded research and development expenses, for 1996, 1997 and 1998 totaled $1.4 million, $2.8 million and $3.3 million, respectively. We expect to continue to expend substantial resources on research and development. The development of compound and single-element substrates is highly complex. There can be no assurance that we will successfully develop and introduce new products in a timely and cost-effective manner or that our development efforts will successfully permit our products to meet changing market demands. For more information regarding the risks relating to our research and development efforts, see "Factors Affecting Future Results -- We must effectively respond to rapid technological changes by continually introducing new products that achieve broad market acceptance."

COMPETITION

The markets for GaAs substrates are intensely competitive. Our principal competitors in the market for semi-insulating GaAs substrates currently include:

- Freiberger;

- Hitachi Cable;

- Litton Airtron; and

- Sumitomo Electric.

In the semi-conducting GaAs substrate market, our principal competitors currently are Sumitomo Electric and Hitachi Cable. We also face competition from manufacturers that produce GaAs substrates for their own use. In addition, we face competition from companies, such as IBM, that are actively developing alternative materials to GaAs. As we enter new markets, such as the Ge and InP substrate markets, we expect

8

to face competitive risks similar to those for its GaAs substrates. Many of our competitors and potential competitors have been in the business longer than us and have greater manufacturing experience, more established technologies than our VGF technique, broader name recognition and significantly greater financial, technical and marketing resources than us. We cannot assure you that we will compete successfully against these competitors in the future or that our competitors or potential competitors will not develop enhancements to the LEC, HB or VGF techniques that will offer price and performance features that are superior to ours. Increased competitive pressure could also lead to intensified price-based competition, resulting in lower prices and margins, which would materially adversely affect our business, financial condition and results of operations.

We believe that the primary competitive factors in the markets in which our products compete are:

- quality,

- price,

- performance,

- customer support and satisfaction, and

- customer commitment to competing technologies.

Our ability to compete in target markets also depends on factors such as:

- the timing and success of the development and introduction of new products by us and our competitors,

- the availability of adequate sources of raw materials, and

- protection of our products by effective utilization of intellectual property laws and general economic conditions.

In order to remain competitive, we believe we must invest significant resources in developing new substrates and in maintaining customer satisfaction worldwide. There can be no assurance that our products will continue to compete favorably or that we will be successful in the face of competition from existing competitors or new companies entering our target markets. If we fail to compete successfully, our financial condition and results of operation would be materially adversely affected.

PROTECTION OF OUR INTELLECTUAL PROPERTY

Our success and competitive position for our VGF technique depends materially on our ability to maintain trade secrets, patents and other intellectual property protections. To protect our trade secrets, we take certain measures to ensure their secrecy, such as executing non-disclosure agreements with our employees, customers and suppliers. Despite our efforts, we cannot assure you that others will not gain access to our trade secrets, or that we can meaningfully protect our intellectual property. In addition, effective trade secret protection may be unavailable or limited in certain foreign countries. Although we intend to protect our rights vigorously, these measures may not be successful.

We rely primarily on the technical and creative ability of our personnel, rather than on patents, to maintain our competitive position. To date, we have been issued one U.S. patent, which relates to our VGF technique, and have two patent applications, one of which relates to our VGF technique, pending. We have one pending application for a Japanese patent but no issued foreign patents. There can be no assurance that our pending applications or any future U.S. or foreign patent applications will be approved, that any issued patents will protect our intellectual property or will not be challenged by third parties, or that the patents of others will not have an adverse effect on our ability to do business. Moreover, the laws of certain foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. We believe that, due to the rapid pace of technological innovation in the GaAs and other substrate markets, our ability to establish and maintain a position of technology leadership in the industry depends more on the skills of our development personnel than upon the legal protections afforded our existing technologies.

9

Although there are currently no pending material lawsuits against us or unresolved notices that we are infringing intellectual property rights of others, we may be notified in the future that we are infringing the patent and/or other intellectual property rights of others. Litigation may be necessary in the future to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. We cannot assure you that we would prevail in any future litigation. Any litigation, whether or not determined in our favor or settled by us, would be costly and would divert the efforts and attention of our management and technical personnel from normal business operations, which would have a material adverse effect on our business, and results of operations. Adverse determinations in litigation could result in the loss of our proprietary rights, subject us to significant liabilities, require us to seek licenses from third parties or prevent us from licensing our technology, any of which could have a material adverse effect on our business and results of operations.

ENVIRONMENTAL REGULATIONS

We are subject to federal, state and local laws and regulations concerning the use, storage, handling, generation, treatment, emission, release, discharge and disposal of certain materials used in our research and development and production operations, as well as laws and regulations concerning environmental remediation and employee health and safety. The growing of crystals and the production of substrates involve the use of certain hazardous raw materials, including, but not limited to, arsenic. We cannot guarantee that our control systems will be successful in preventing a release of these materials or other adverse environmental conditions. Any release or other failure to comply with present or future environmental laws and regulations could result in the imposition of significant fines against us, the suspension of production or a cessation of operations. In addition, there can be no assurance that existing or future changes in laws or regulations will not require expenditures or liabilities to be incurred by us, or in restrictions on our operations. At December 31, 1998, we believe we were in substantial compliance with all applicable environmental regulations.

BACKLOG

We include in backlog only those customer orders which have been accepted by us and which shipment is generally expected within 12 months. As of December 31, 1998, our backlog was approximately $8.7 million. Backlog can fluctuate greatly based upon, among other matters, the timing of orders. In addition, purchase orders in our backlog are subject to changes in delivery schedules or to reduction in size or cancellation at the option of the purchaser without significant penalty. We have experienced, and may continue to experience, cancellation, reduction and rescheduled delivery of orders in our backlog. Our backlog may vary significantly from time to time depending upon the level of capacity available to satisfy unfilled orders. Accordingly, although useful for scheduling production, backlog as of any particular date may not be a reliable indicator of sales for any future period.

EMPLOYEES

As of December 31, 1998, we had 314 full-time employees, of whom 263 were principally engaged in manufacturing, 32 in sales, general and administration and 19 in research and development. Our success is in part dependent on our ability to attract and retain highly skilled workers, who are in high demand in the Silicon Valley area. None of our employees is represented by a union and we have never experienced a work stoppage. Management considers its relations with its employees to be good.

ITEM 3. LEGAL PROCEEDINGS

In October 1998, a vendor submitted a claim against us to the Arbitration Commission in Shenzhen, China, alleging that we failed to honor our obligation to take delivery of the full quantity of Ge under a purchase contract with the vendor. We believe that this action is without merit and will continue to vigorously defend our position. We expect the cost of defending this matter will not materially adversely affect our operating results through fiscal 1999. However, there can be no assurance that our defense of this matter will be successful.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None.

ITEM 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management's Discussion and Analysis of Financial Condition and Results of Operations includes a number of forward-looking statements which reflect current views with respect to future events and financial performance. These forward-looking statements are subject to certain risks and uncertainties, including those discussed in the "Factors Affecting Future Results" and elsewhere in this report that could cause actual results to differ materially from historical results or those anticipated. In this report, the words "anticipates," "believes," "expects," "future," "intends," and similar expressions identify forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.

RESULTS OF OPERATIONS

Overview

We use a proprietary VGF technique to produce high-performance compound semiconductor substrates for use in a variety of electronic and opto-electronic applications. We were founded in 1986 and commenced product sales in 1990. We currently sell GaAs, InP and GaN substrates to manufacturers of semiconductor devices for use in applications such as wireless and fiber optic telecommunications, lasers, LEDs, and consumer electronics. We also sell Ge substrates for use in satellite solar cells.

We have been profitable on an annual basis since 1990 and our total revenues were $16.2 million, $25.3 million and $43.3 million for the years ended December 31, 1996, 1997 and 1998, respectively. Total revenues consist of product revenues and contract revenues. Our product revenues were $14.2 million, $23.0 million and $41.5 million for the years ended December 31, 1996, 1997 and 1998, respectively. Product revenues are generally recognized upon shipment of products to customers. Historically, virtually all of our product revenues have been derived from sales of GaAs substrates, which, in the years ended December 31, 1997 and 1998, accounted for 95.0% and 81.8%, respectively, of the our product revenues. We began selling InP and Ge substrates to our customers in late 1997 and GaN substrates in late 1998.

Our contract revenues were $2.0 million, $2.3 million and $1.8 million for the years ended December 31, 1996, 1997 and 1998, respectively. Contract revenues are recognized under the percentage of completion method and related research costs are included in cost of contract revenues. Contract revenues consist of research and development contracts with U.S. government agencies and customer-funded research projects. The largest of the government contracts was a four-year U.S. Department of Defense Title III Program for development of GaAs substrates (the "Title III GaAs contract"), which was awarded to us in March 1994 and under which we were paid an aggregate of $6.1 million. The Title III GaAs contract was completed in 1998. We retain rights to the VGF and wafer fabrication technology developed under these government and customer-funded research contracts and are therefore able to leverage these programs to continue to broaden our product and technology offerings.

In 1995, we established a wholly-owned subsidiary in Japan to distribute our products. This subsidiary serves primarily as a direct sales and support office for our customers in Japan. We also utilize independent sales representatives in France, Japan, South Korea, Taiwan and the United Kingdom. Domestic sales are generated by our direct sales force. International sales, excluding Canada, accounted for 35.0%, 34.1% and 28.8% of total revenues for the years ended December 31, 1996, 1997 and 1998, respectively. Except for sales in Japan, which are denominated in yen, we denominate and collect our international sales in U.S. dollars. Doing business in Japan subjects us to fluctuations in exchange rates between the U.S. dollar and the Japanese yen. We incurred foreign exchange losses of $114,000, $186,000 and $24,000 for the years ended December 31, 1996, 1997 and 1998, respectively. During the year ended December 31, 1998, we bought foreign exchange contracts to hedge against certain trade accounts receivable in Japanese yen. The outstanding commitments with respect to such foreign exchange contracts had a total value of approximately $1.6 million as of December 31, 1998.

Since July 1996, we have conducted all of our operations in a 50,000 square foot office and production facility located in Fremont, California. Prior to transitioning our manufacturing operations to this facility, we

15

leased a 20,000 square foot manufacturing facility in Dublin, California. In late 1998, we expanded the size of our current manufacturing facility by approximately 30,000 square feet to meet our anticipated future production needs through 1999. In June 1998, we purchased an additional 58,000 square foot facility in Fremont, California directly across the street from our existing manufacturing facility and moved marketing, sales, engineering and administrative personnel into a portion of the building. We believe that this new facility will not be used for production of substrates prior to the end of 1999. In January 1999, we announced we had received a business license for operations in Beijing, China and had purchased a 30,000 square foot facility in a major tax-free industrial park in Beijing. This facility is expected to be operational during the second quarter of 1999. We expect that our proprietary VGF crystal growth operations will continue to be housed in Fremont, California, and our other manufacturing operations will be conducted in both Fremont and Beijing.

In connection with the granting of stock options, we recorded aggregate deferred compensation of $322,000 and $203,000, representing the difference between the deemed fair value of the Common Stock for accounting purposes and the option exercise price at the date of grant for the years ended December 31, 1997 and 1998, respectively. This deferred compensation will be amortized over the vesting period of the applicable options of which $102,000 and $96,000 was amortized during the years ended December 31, 1997 and 1998, respectively.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1998

Revenues. Total revenues increased 70.9% from $25.3 million for the year ended December 31, 1997 to $43.3 million for year ended December 31, 1998. Product revenues increased 80.3% from $23.0 million for the year ended December 31, 1997 to $41.5 million for the year ended December 31, 1998. The increase in product revenues reflected an increase in the volume of sales of GaAs and InP substrates to existing domestic and international customers, the addition of new customers and the introduction of Ge substrates in the fourth quarter of 1997. Ge substrates totaled 15.6% of product revenues for the year ended December 31, 1998 compared to only 3.6% in 1997.

International revenues, excluding Canada, decreased from 34.1% of total revenues for the year ended December 31, 1997 to 28.8% of total revenues for the year ended December 31, 1998, primarily reflecting the introduction of Ge substrates in late 1997, which are currently sold only to domestic customers. We believe that Ge substrates will be sold only to U.S. customers for the foreseeable future, which is expected to cause our international revenues to decline as a percentage of total revenues.

Contract revenues decreased 22.6% from $2.3 million for the year ended December 31, 1997 to $1.8 million for the year ended December 31, 1998. Contract revenues in 1997 were higher than in 1998 primarily because we recognized significant revenue from a $1.2 million customer-funded Ge substrates research contract that was completed in June 1997. Contract revenues declined from 9.2% of total revenues for the year ended December 31, 1997 to 4.2% for the year ended December 31, 1998 as a result of product revenue growth combined with a decline in contract revenues. In future periods, we expect contract revenues to continue to decline as a percentage of total revenues.

Gross margin. Gross margin increased from 39.9% for the year ended December 31, 1997 to 41.4% for the year ended December 31, 1998. Product gross margin increased slightly from 40.6% for the year ended December 31, 1997 to 40.8% for the year ended December 31,1998, reflecting the higher yields achieved in GaAs and InP production, partially offset by lower margins from Ge substrates.

Contract gross margins increased from 33.1% for the year ended December 31,1997 to 55.3% for the year ended December 31, 1998. This increase was due to a shift in contract revenue mix from a lower margin customer-funded contract for Ge substrates research completed in June 1997 to higher margin government contracts.

Selling, general and administrative expenses. Selling, general and administrative expenses increased 69.5% from $3.0 million for the year ended December 31, 1997 to $5.0 million for the year ended December 31, 1998. This increase resulted primarily from increased personnel and administrative expenses required to support additional sales volume. Selling, general and administrative expenses as a percentage of total revenues decreased slightly from 11.7% for the year ended December 31,1997 to 11.5% for the year ended December 31, 1998.

Research and development expenses. Research and development expenses increased 94.3% from $1.3 million for the year ended December 31, 1997 to $2.5 million for the year ended December 31, 1998. This increase resulted primarily from the hiring of additional engineers and the purchase of materials to develop new products and to enhance existing products. In addition to our funded research and development, we incurred research and development expenses relating to government and customer-funded research contracts, which are included in the cost of contract revenues. For the year ended December 31, 1998, total research and

17

development costs, including both contract funded and internally funded research and development expenses, totaled $3.3 million, or 7.6% of total revenues.

Interest expense. Interest expense increased from $570,000 for the year ended December 31, 1997 to $781,000 for the year ended December 31, 1998. This increase was primarily the result of additional borrowings in 1998 we incurred to finance the purchase of the our new building and to finance expansion of production facilities and related equipment purchases.

Interest and other income (expense). Interest and other income (expense) increased from $34,000 of expense for the year ended December 31, 1997 to $568,000 of income for the year ended December 31, 1998. This increase was primarily the result of interest income earned on the $25.8 million in net proceeds raised from our initial public offering in May 1998.

Provision for Income Taxes. Income tax expense remained at 38.0% of income before provision for income taxes for the years ended December 31, 1997 and 1998.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1997

Revenues. Total revenues increased 56.1% from $16.2 million for the year ended December 31, 1996 to $25.3 million for the year ended December 31, 1997. Product revenues increased 61.8% from $14.2 million for the year ended December 31, 1996 to $23.0 million for the year ended December 31, 1997. The increase in product revenues reflected an increase in the volume of sales of GaAs substrates to existing domestic and international customers, sales to new customers and the introduction of Ge substrates in the fourth quarter of 1997.

International revenues, excluding Canada, decreased from 35.0% of total revenues for the year ended December 31, 1996 to 34.1% of total revenues for the year ended December 31, 1997, primarily reflecting the introduction of Ge substrates in late 1997, which were sold only to U.S. customers.

Contract revenues increased 15.8% from $2.0 million for the year ended December 31, 1996 to $2.3 million for the year ended December 31, 1997. This increase was primarily due to revenues recognized from a $1.2 million customer-funded Ge substrates research contract that was completed in 1997. This increase was partially offset by a reduction in government contract revenues. Contract revenues declined from 12.4% of total revenues for the year ended December 31, 1996 to 9.2% for the year ended December 31, 1997 as a result of product revenue growth exceeding contract revenue growth.

Gross margin. Gross margin increased from 38.0% for the year ended December 31, 1996 to 39.9% for the year ended December 31, 1997. Product gross margin increased from 34.8% for the year ended December 31, 1996 to 40.6% for the year ended December 31, 1997. The lower product gross margin in 1996 resulted primarily from duplicate expenses of approximately $500,000 due to simultaneous operations of two facilities and manufacturing inefficiencies relating to the transition to our new production facility.

Contract gross margin declined from 60.3% for the year ended December 31, 1996 to 33.1% for the year ended December 31, 1997. This decrease was due to a shift in contract revenue mix from higher margin government research contracts in 1996 to a lower margin customer-funded contract for Ge substrates research. In addition, in 1996 gross margin was favorably impacted by large incentive awards which we were paid upon completion of certain milestones of the Title III GaAs contract.

Selling, general and administrative expenses Selling, general and administrative expenses increased 45.5% from $2.0 million for the year ended December 31, 1996 to $3.0 million for the year ended December 31, 1997. This increase resulted primarily from increased domestic and international sales personnel and administrative expenses required to support increased sales volume.

Research and development expenses. Research and development expenses increased 117.7% from $592,000 for the year ended December 31, 1996 to $1.3 million for the year ended December 31, 1997. This increase resulted primarily from the hiring of additional engineers to develop new products and to enhance existing products. For the year ended December 31, 1997, total research and development costs, including

18

both contract funded and internally funded research and development expenses, totaled $2.8 million, or 11.2% of total revenues.

Interest expense. Interest expense increased from $170,000 for the year ended December 31, 1996 to $570,000 for the year ended December 31, 1997. This increase resulted primarily from additional borrowings incurred in 1996 to finance our new manufacturing facility, the expansion of production facilities in 1997 and related equipment purchases.

Interest and other income (expense). Interest and other income (expense) decreased from $72,000 of expense for the year ended December 31, 1996 to $34,000 of expense for the year ended December 31, 1997. This decrease was due to higher interest income generated on investments from the proceeds of a $5.9 million private equity financing completed in March 1997, partially offset by foreign currency transaction losses incurred due to the increase in the value of the U.S. dollar compared to the Japanese yen.

Provision for income taxes. Income tax expense was virtually unchanged from 37.9% of income before provision for income taxes for the year ended December 31, 1996 to 38.0% of income before provision for income taxes for the year ended December 31, 1997.

Our total revenues have increased in each of the eight quarters ended December 31, 1998, except for the quarter ended December 31, 1998, which was comparable to the prior quarter. These quarterly increases reflect increased product shipments to both the semi-insulating and semi-conducting GaAs and InP markets and the introduction of Ge substrates in the quarter ended December 31, 1997. In the quarter ended December 31, 1998, revenues from the sales of Ge substrates declined by $1.2 million from the prior quarter as a result of a major customer having excess inventory and deferring shipments. This decline in revenues was offset by a $1.2 million increase in GaAs shipments due primarily to increased orders from Southeast Asia for semi-conducting substrates. Contract revenues increased in the quarters ended March 31 and June 30, 1997 primarily as a result of revenues recognized from a $1.2 million customer-funded Ge substrates research contract. Contract revenues decreased in the quarter ended December 31, 1998 due primarily to the temporary reduction in the level of work performed on contracts in progress.

We experienced higher product gross margins in the four quarters of 1997 primarily as a result of better product yields achieved from the new production facility completed in 1996 and improved manufacturing efficiencies from larger production volumes. In addition, due to a recycling program implemented in the quarter ended December 31, 1997, we were able to recycle scrapped inventory that had accumulated over prior quarters. This recycling program had a significant positive impact on the product gross margin for the quarter ended December 31, 1997. While we will continue the recycling program, we expect the program to have a less significant impact on product gross margins in the future as evidenced by the decline in product gross

20

margins for March 31, 1998. The increase in the overall product gross margin in the quarter ended December 31, 1997 was partially offset by lower product gross margins from sales of Ge substrates, which have lower gross margins than GaAs and InP substrates. The decrease in the overall product gross margins for the first three quarters of 1998 was primarily due to an increase in sales of Ge substrates. We experienced significantly lower contract gross margins for the quarters ended March 31, 1997 and June 30, 1997 due to a shift in contract revenue mix from higher margin government research contracts in prior quarters to a lower margin customer-funded contract for Ge substrates research. The decrease in contract gross margin from the quarter ended December 31, 1997 to the quarter ended March 31, 1998 was due to a shift in contract revenue mix from higher margin government research contracts in prior quarters to a lower margin cost sharing contract for InP substrates research. Contract gross margin in the quarter ended September 30, 1998 was favorably impacted by the recognition of certain performance incentives under the Title III GaAs contract. The lower contract gross margin in the quarter ended December 31, 1998 was primarily due to the lower margin on the cost sharing contract for InP substrates research.

Selling, general and administrative expenses for the quarter ended December 31, 1997 were higher than the quarters ended June 30 and September 30, 1997, as we built our management infrastructure to support its increased sales volume. Selling, General and administrative expenses for the quarter ended December 31, 1998 were significantly higher than the previous three quarters due primarily to increases in our bad debt allowance to cover exposure from increased international sales and for legal expenses in connection with an arbitration case.

Research and development expenses for the four quarters ended September 30, 1998 significantly increased over the prior three quarters ended September 30, 1997, primarily due to increased new product research and materials purchased for research on InP substrates. Research and development expenses for the quarter ended December 31, 1998 decreased primarily due to lower material purchases for three research projects.

We believe that our quarterly and annual revenues, expenses and operating results could vary significantly in the future and that period-to-period comparisons should not be relied upon as indications of future performance. There can be no assurance that our revenues will grow in future periods or that it will sustain its level of total revenues or its rate of revenue growth on a quarterly or annual basis. We may, in some future quarter, have operating results that will be below the expectations of stock market analysts and investors. In such event, the price of the our common stock could be materially adversely affected.

LIQUIDITY AND CAPITAL RESOURCES

During the past five years, we have funded our operations primarily from cash provided by operations, short-term and long-term borrowings and a private financing of $5.9 million for preferred stock completed in March 1997. We completed our initial public offering in May 1998, and raised net proceeds of approximately $25.8 million. As of December 31, 1998, we had working capital of $40.8 million, including cash and cash equivalents of $16.1 million, compared to working capital at December 31, 1997 of $14.2 million, including cash of $3.1 million, and compared to working capital at December 31, 1996 of $5.5 million, including cash of $756,000.

During the year ended December 31, 1996, net cash provided by operations of $474,000 was due primarily to net income of $2.0 million, depreciation of $867,000 and an increase in accounts payable and accrued liabilities of $629,000, offset in part by increases in inventory of $2.3 million, and accounts receivable and other assets of $727,000. The increase in inventory was primarily due to increases in raw material and work-in-process inventory to provide an adequate supply of material in anticipation of large orders for the upcoming year. These inventory increases resulted in a decrease in the inventory turnover ratio from 4.5 turns per year at December 31, 1995 to 3.3 turns per year at December 31, 1996. The increase in accounts receivable was primarily a result of increased sales in Japan, which generally have longer payment cycles. The increase in sales to Japan also adversely impacted days sales outstanding, which increased from 49 days at December 31, 1995 to 60 days at December 31, 1996.

21

During the year ended December 31, 1997, net cash used in operations of $1.2 million was primarily due to increases in inventory of $4.4 million and accounts receivable of $3.0 million, offset in part by net income of $3.3 million, depreciation of $1.2 million and increases in accounts payable and accrued liabilities of $1.6 million. The increase in inventory during this period included additional Ge inventory, which primarily resulted in a decrease in the inventory turnover ratio from 3.3 turns per year at December 31, 1996 to 2.2 turns per year at December 31, 1997. The increases in accounts payable and accrued liabilities, accounts receivable and inventory were primarily the result of a 56.1% increase in revenues from the prior year. In addition, accounts receivable increased due to the increase in international revenues, which historically have longer payment cycles. This increase in payment cycles resulted in an increase in days sales outstanding from 60 days at December 31, 1996 to 64 days at December 31, 1997.

During the year ended December 31, 1998, net cash used in operations of $6.3 million was primarily due to increases in inventory of $12.2 million, accounts receivable of $2.9 million and prepaid and other assets of $1.6 million, offset in part by net income of $6.3 million, depreciation of $2.0 million, and increases in accounts payable of $1.7 million and accrued liabilities of $496,000. The increases in accounts receivable, inventory and accounts payable were primarily the result of the 70.9% increase in total revenues from the prior year. In addition, inventory increased due to our decision to maintain the Ge substrates production line during the fourth quarter of 1998 in anticipation of future large orders, although shipments to a large customer had been deferred. Accordingly, the inventory turnover ratio declined from 2.2 turns per year at December 31, 1997 to 1.7 turns per year at December 31, 1998. The increase in prepaid and other assets was due primarily to deposits on manufacturing equipment and materials for our new Beijing, China facility and U.S. operations and for increases in prepaid insurance, taxable bond fees and bank fees. The increase in accrued liabilities was the result of an increase in legal expenses in connection with an arbitration case, and higher vacation and payroll expenses due to the increased number of personnel. Days sales outstanding decreased from 64 days at December 31, 1997 to 62 days at December 31, 1998, reflecting improved collection efforts.

Net cash used in investing activities was $3.9 million, $4.9 million, and $16.4 million for the years ended December 31, 1996, 1997 and 1998, respectively, which amounts were attributed in each period to the purchase of property, plant and equipment. For the year ended December 31, 1998, the property acquired included our new 58,000 square foot building at a cost of $9.0 million and the 30,000 square foot addition for $2.0 million.

Net cash provided by financing activities was $3.5 million, $8.4 million and $35.5 million for the years ended December 31, 1996, 1997 and 1998, respectively. For the year ended December 31, 1996, net cash provided by financing activities resulted primarily from long-term borrowings of $3.5 million to complete our manufacturing facility. For the year ended December 31, 1997, net cash provided by financing activities resulted primarily from the issuance of $5.9 million of preferred stock and $2.7 million for long-term bank borrowings, partially offset by the repayment of $300,000 of short-term borrowings. For the year ended December 31, 1998, net cash provided by financing activities consisted primarily of net proceeds of $25.8 million from our initial public offering and long-term net borrowings of $9.6 million. Long-term net borrowings reflected the issuance of $11.6 million in taxable variable rate revenue bonds in November 1998 and equipment loans in the amount of $2.3 million less repayment of existing long-term debts in the amount of $4.3 million. Long-term borrowings were used for the purchase of the new 58,000 square foot facility, for construction of the additional 30,000 square foot manufacturing space and related equipment.

We have generally financed our equipment purchases through secured equipment loans over five-year terms at interest rates ranging from 6.0% to 9.0% per annum. Our manufacturing facilities have been financed by long-term borrowings, which were repaid by the taxable variable rate revenue bonds in 1998, except for a $1.0 million SBA loan. The SBA loan has an interest rate of 7.3% per annum, matures in 2016 and is subordinated to the taxable variable rate revenue bonds. The taxable variable rate revenue bonds have a term of 25 years and mature in 2023 with an interest rate at 200 basis points below the prime rate and are traded in the public market. Repayment of principal and interest under the bonds is secured by a letter of credit from our bank and is paid on a quarterly basis. We have the option to redeem in whole or in part the bonds during their term. At December 31, 1998, $11.6 million was outstanding under the taxable variable rate revenue bonds.

22

We currently have a $15.0 million line of credit with a commercial bank at an interest rate equal to the prime rate plus one-half percent. This line of credit is secured by all business assets, less equipment, and expires in May 1999. This line of credit is subject to certain financial covenants regarding current financial ratios and cash flow requirements, which were met as of December 31, 1998. We must obtain the lender's approval to obtain additional borrowings or to further pledge our assets, except for borrowings secured by the pledge of equipment or obtained in the normal course of business. At December 31, 1998, no amount was outstanding under the $15.0 million line of credit.

We anticipate that the combination of existing working capital and the borrowings available under current credit agreements will be sufficient to fund working capital and capital expenditure requirements for the next 12 months. Our future capital requirements will depend on many factors, including the rate of revenue growth, our profitability, the timing and extent of spending to support research and development programs, the expansion of selling and marketing and administrative activities, and market acceptance of our products. We expect that we may need to raise additional equity or debt financing in the future, although we are not currently negotiating for additional financing nor do we have any plans to obtain additional financing at this time. There can be no assurance that additional equity or debt financing, if required, will be available on the acceptable terms or at all. If we are unable to obtain such additional capital, if needed, we may be required to reduce the scope of our planned product development and selling and marketing activities, which would have a material adverse effect on our business, financial condition and results of operations. In the event that we do raise additional equity financing, further dilution to our investors will result.

YEAR 2000 READINESS

Some computers, software, and other equipment include computer code in which calendar year data is abbreviated to only two digits. As a result of this design decision, some of these systems could fail to operate or fail to produce correct results if "00" is interpreted to mean 1900, rather than 2000. These problems are widely expected to increase in frequency and severity as the year 2000 approaches, and are commonly referred to as the "year 2000 problem."

Assessment. The year 2000 problem affects the computers, software and other equipment that we use, operate or maintain for our operations. Accordingly, we have organized a program team responsible for monitoring the assessment and remediation status of our year 2000 projects and reporting such status to our board of directors. This project team is currently assessing the potential effect and costs of remediating the year 2000 problem for our internal systems. To date, we have obtained verification or validation from our significant equipment and system vendors that the software programs and applications and related hardware that we use, operate or maintain for our operations are compliant with the year 2000.

Internal infrastructure. We believe that we have identified and evaluated all of the major computers, software applications and related equipment used in connection with our internal operations to determine if they must be modified, upgraded or replaced to minimize the possibility of a material disruption to our business. We are in the process of modifying, upgrading, and replacing major systems that have been assessed as adversely affected, and expect to complete this process before the end of fiscal 1999. As of December 31, 1998, we have incurred approximately $300,000 in this process.

Systems other than information technology systems. In addition to computers and related systems, the operation of office and facilities equipment, such as fax machines, telephone switches, security systems, and other common devices may be affected by the year 2000 problem. We are currently assessing the potential effect and costs of remediating the year 2000 problem on our office equipment at our facilities in Fremont, California. We estimate the total cost to us of completing any required modifications, upgrades or replacements of our internal systems will not exceed $100,000, almost all of which we believe will be incurred during 1999. This estimate is being monitored and we will revise it as additional information becomes available.

Based on the activities described above, we do not believe that the year 2000 problem will have a material adverse effect on our business or operating results.

23

Suppliers. We are in the process of contacting third-party suppliers of components used in the manufacture of our products to identify and, to the extent possible, resolve issues involving the year 2000 problem. However, we have limited or no control over the actions of these third-party suppliers. Thus, while we expect that we will be able to resolve any significant year 2000 problems with these third parties, there can be no assurance that these suppliers will resolve any or all year 2000 problems before the occurrence of a material disruption to the operation of our business. Any failure of these third parties to timely resolve year 2000 problems with their systems could have a material adverse effect on our business, operating results and financial condition.

Most likely consequences of year 2000 problems. We expect to identify and resolve all year 2000 problems that could materially adversely affect our business operations. However, we believe that it is not possible to determine with complete certainty that all year 2000 problems affecting us have been identified or corrected. The number of devices that could be affected and the interactions among these devices are simply too numerous. In addition, no one can accurately predict how many year 2000 problem-related failures will occur or the severity, duration, or financial consequences of these perhaps inevitable failures. As a result, we believe that the following consequences are possible:

- a significant number of operational inconveniences and inefficiencies for us, our contract manufacturers and our customers that will divert management's time and attention and financial and human resources from ordinary business activities;

- business disputes and claims for pricing adjustments or penalties due to year 2000 problems by our customers, which we believe will be resolved in the ordinary course of business; and

- business disputes alleging that we failed to comply with the terms of contracts or industry standards of performance, some of which could result in litigation or contract termination.

Contingency plans. We are currently developing contingency plans to be implemented if our efforts to identify and correct year 2000 problems affecting our internal systems are not effective. We expect to complete our contingency plans by the end of August 1999. Depending on the systems affected, these plans could include:

- accelerated replacement of affected equipment or software; short- to medium-term use of backup equipment and software; increased work hours for our personnel; and use of contract personnel to correct on an accelerated schedule any year 2000 problems that arise or to provide manual workarounds for information systems.

Our implementation of any of these contingency plans could have a material adverse effect on our business, operating results and financial condition.

Disclaimer. The discussion of our efforts and expectations relating to year 2000 compliance are forward-looking statements. Our ability to achieve year 2000 compliance and the level of incremental costs associated therewith, could be adversely affected by, among other things, the availability and cost of programming and testing resources, third party suppliers' ability to modify proprietary software, and unanticipated problems identified in the ongoing compliance review.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 established a new model for accounting for derivatives and hedging activities and supersede and amend a number of existing accounting standards. SFAS 133 requires that all derivative be recognized in the balance sheet at their fair market value. In addition, corresponding derivative gains and losses should be either reported in the statement of operations or stockholders' equity, depending on the type of hedging relationship that exists with respect to such derivatives. Adopting the provisions of SFAS 133, which will be effective in fiscal year 2000, is not expected to have a material effect on the Company's consolidated financial statements.

FACTORS AFFECTING FUTURE RESULTS

In addition to the other information in this report, the following factors should be considered carefully in evaluating our business before purchasing shares of our stock.

A number of factors could cause our quarterly financial results to be worse than expected, resulting in a decline in our stock price. Although we have been profitable on an annualized basis since 1990, due to the foregoing factors, we believe that period-to-period comparisons of our operating results cannot be relied upon as an indicator of our future performance. It is likely that in some future quarter, our operating results may be below the expectations of public market analysts or investors. If this occurs, the price of our common stock would likely decrease. For more information regarding our results, see "Management's Discussion and Analysis of Financial Condition and Results of Operations".

Our quarterly and annual revenues and operating results have varied significantly in the past and may vary significantly in the future due to a number of factors, including:

- fluctuations in demand for our substrates due to reduction in the value of Asian currencies and the turmoil in the Asian financial markets;

- our expense levels and expected research and development requirements;

- our ability to develop and bring to market new products on a timely basis;

- the volume and timing of orders from our customers;

- the availability of raw materials;

- fluctuations in manufacturing yields;

- our manufacturing expansion in Beijing, China;

- changes in the unit of products sold;

- introduction of products and technologies by our competitors; and

- costs relating to possible acquisitions and integration of technologies or businesses.

For more information regarding our results, see "Management's Discussion and Analysis of Financial Condition and Results of Operations."

VGF is a new technique for producing substrates which must achieve widespread acceptance if we are to succeed. We believe that our competitors principally utilize the traditional LEC or HB crystal growing processes for producing semi-insulating and semi-conducting GaAs substrates. We further believe that we are the only high-volume supplier of semi-insulating and semi-conducting GaAs substrates which utilize the VGF technique, a newer technology than either the LEC or HB techniques. We cannot assure you that our current customers will continue to use our VGF-produced substrates or that additional companies will purchase our products manufactured from the VGF technique. Failure to gain increased market acceptance of our VGF technique by either current or prospective customers could materially adversely affect our operating results.

A significant portion of our prospective customers are wireless communications manufacturers, fiber optic communications manufacturers and manufacturers of other high-speed semiconductor devices that use GaAs substrates produced using either the LEC or HB techniques. To establish the VGF technique as a preferred process for producing substrates for prospective customers, we must offer products with superior prices and performance on a timely basis and in sufficient volumes. We must also overcome the reluctance of these customers to purchase our GaAs substrates due to possible perceptions of risks relating to concerns about the quality and cost-effectiveness of our GaAs substrates when compared to substrates produced by the traditional LEC or HB techniques. In addition, potential GaAs substrate customers may be reluctant to rely on a relatively small company for critical materials used to manufacture their semiconductor devices.

If we do not achieve acceptable yields of crystals and the successful and timely production of substrates, the shipment of our products would be delayed and our business adversely affected. The highly complex

25

processes of growing crystals as well as other steps involved in manufacturing substrates which we engage in can be adversely affected by a number of factors, including the following:

- chemical or physical defects in the crystals;

- contamination of the manufacturing environment;

- substrate breakage;

- equipment failure; and

- performance of personnel involved in the manufacturing process.

We have been adversely affected in the past due to the occurrence of a combination of these factors which resulted in product shipment delays and adversely affected our business.

A significant portion of our manufacturing costs are fixed. As a result, we must increase the production volume of substrates and improve yields in order to reduce unit costs, increase margins and maintain and improve our results of operations. Such decreases in production volume and yields could materially adversely affect our business, financial condition and results of operations.

In the past, we have sometimes manufactured substrates which have not met certain customers' manufacturing process requirements. We have fixed such occurrences through minor changes to the substrates or the manufacturing process. Recurrence of such problems and our inability to solve them may materially hurt our performance.

We have begun producing and shipping Ge and InP substrates in commercial volume. We also understand that we must achieve the same manufacturing capability for six inch GaAs wafers. We cannot assure you that we will be able to manufacture the Ge and InP substrate or the larger GaAs substrates in commercial volumes with acceptable yields. Our business, financial condition and results of operations would be materially adversely affected if we experience low yields of these substrates.

Because substantially all of our revenue is derived from sales of our GaAs substrates, we are dependent on widespread market acceptance of these products. We currently derive substantially all of our revenues from sales of our GaAs substrates. We expect that revenue from GaAs substrates will account for a significant majority of our revenues for the next several years. GaAs substrates are primarily used in electronic applications such as wireless communications, fiber optic communications and other high-speed semiconductor devices, as well as in opto-electronic applications such as lasers and LEDs. If there is a decrease in demand for GaAs substrates by semiconductor device manufacturers or if new substrates for these electronic and opto-electronic applications are developed and successfully introduced by competitors, our revenues may decline and our business will be materially adversely affected.

Further, other companies, including IBM, are actively involved in developing other devices which could provide the same high-performance, low power capabilities as GaAs-based devices at competitive prices, such as silicon-germanium based devices for use in certain wireless applications. If these silicon-germanium based devices are successfully developed and are adopted by semiconductor device manufacturers, demand for GaAs substrates could decrease. This development could cause our revenues to fall, which could adversely affect our business, financial condition and results of operations.

In order to be successful, we must develop and introduce in a timely manner new substrates and continue to improve our current substrates to address customer requirements and compete effectively on the basis of price and performance. Recently, we have begun commercial shipments of Ge and InP substrates and are currently developing other substrates, including gallium phosphide and gallium nitride. Factors that may affect the success of product improvements and product introductions include the development of markets for such improvements and substrates, achievement of acceptable yields, price and market acceptance. Many of these factors are beyond our control. We cannot assure you that our product development efforts will be successful or that our new products will achieve market acceptance. To the extent that product improvements and new product introductions do not achieve market acceptance, our business, financial condition and results of operations would be materially adversely affected.

26

Our limited ability to protect our intellectual property may adversely affect our ability to compete. We rely on a combination of patents, copyrights, trademarks and trade secret laws and contractual restrictions on employees, consultants and third parties from disclosure to protect our intellectual property rights. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Policing unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. We believe that, due to the rapid pace of technological innovation in the GaAs and other substrate markets, our ability to establish and maintain a position of technology leadership in the industry depends more on the skills of our development personnel than upon the legal protections afforded our existing technologies.

To date, we have been issued one U.S. patent, which relates to the VGF technique, and have two U.S. patent applications pending, one which relates to the VGF technique. Additionally, we have one pending application for a Japanese patent but no issued foreign patents. We cannot assure you that:

- the pending or any future U.S. or foreign patent applications will be approved;

- any issued patents will protect our intellectual property;

- third parties will not challenge the ownership rights of the patents or the validity of the patent applications;

- the patents owned by others will not have an adverse effect on our ability to do business; or

- others will not independently develop similar or competing technology or design around any patents issued to us.

Moreover, the laws of certain foreign countries may not lend protection to our patents to the same extent as the laws of the United States. See "Business-Intellectual property" for more information regarding risks relating to protecting our intellectual property rights.

If we infringe the proprietary rights of others, we may be forced to enter costly royalty or licensing agreements. We could in the future receive a claim that we are infringing the patent, trademark, copyright or other proprietary rights of other third parties. If any claims were asserted against us for violation of patent, trademark, copyright or other similar laws as a result of the use by us, our customers or other third parties of our products, those claims would be costly and time-consuming to defend, would divert our management's attention and could cause product delays. In addition, if we discovered we violated other third party rights, we could be required to enter into costly royalty or licensing agreements as a result of such claims. These royalty or licensing agreements may adversely affect our operating results.

If we fail to comply with stringent environmental regulations, we may be subject to significant fines or the cessation of our operations. We are subject to federal, state and local environmental laws and regulations. Any failure to comply with present or future environmental laws and regulations could result in the imposition of significant fines on us, the suspension of production or a cessation of operations. In addition, existing or future changes in laws or regulations may require us to incur further significant expenditures or liabilities, or additional restriction in our operations. For more information regarding environmental regulations that affect our operations, see "Business -- Environmental regulations."

We purchase critical raw materials required to grow crystals from single or limited sources, and could lose sales if these sources fail to fill our needs. We do not have any long-term supply contracts with any of our suppliers, and we currently purchase raw materials required to grow crystals from single or a limited number of suppliers. For example, we purchase a majority of the gallium we use from Rhone-Poulenc.

Due to our reliance on a limited group of suppliers, we are exposed to several risks such as the potential inability to obtain adequate supply of materials, reduced control over pricing of our products and meeting customer delivery schedules.

We have experienced delays receiving orders of certain materials due to shortages. We may continue to experience these delays due to shortages of materials and as a result be subject to higher costs. Although we

27

attempt to preempt supply interruptions by maintaining adequate levels of inventory of critical materials and attempts to obtain additional suppliers, shortages or price increases caused by suppliers may nevertheless recur.

If we are unable to receive adequate and timely deliveries of critical raw materials, relationships with current and future customers could be harmed, which could materially adversely affect our business, financial condition and results of operations.

We are subject to additional risks as a result of the recent completion of a new manufacturing facility. In connection with further expanding our manufacturing capacity, we purchased an additional 58,000 square foot facility in Fremont, California and a 30,000 square foot facility in Beijing, China. in 1998. The improvements to the new facility subject us to significant risks, including:

- unavailability or late delivery of process equipment;

- unforeseen engineering problems;

- work stoppages;

- unanticipated cost increases; and

- unexpected changes or concessions required by local, state or federal regulatory agencies with respect to necessary licenses, land use permits and building permits.

If any of the above occur, it could materially adversely affect operations under the new facility which in turn would materially adversely affect our business, financial condition and results of operations.

Finally, the operation of the new facility, together with the recent expansion of our current facility by approximately 30,000 square feet, will also expose us to additional risks. For example, the additional fixed operating expenses associated with the new facility may only be offset by sufficient increases in product revenues. We cannot assure you that the demand for our products will grow as we currently expect, and if this does not occur, we would not be able to offset the costs of operating the new facility, which may materially adversely affect our results of operations.

We must effectively respond to rapid technological changes by continually introducing new products that achieve broad market acceptance. We and our customers compete in a market that is characterized by rapid technological changes and continuous improvements in substrates. Accordingly, our future success depends upon whether we can apply our proprietary VGF technique to develop new substrates that meet the needs of customers and compete effectively on the basis of quality, price and performance. If we are unable to timely develop new, economically viable products that meet market demands, our revenues will decline, which could adversely affect our results of operation and cause the price of our stock to fall.

It is difficult to predict accurately the time required and the costs involved in researching, developing and engineering new products. Thus, our actual development costs could exceed budgeted amounts and our product development schedules could require extension. We have experienced product development delays in the past and may experience similar delays in the future which could materially adversely affect our business. For example, our introduction of InP substrates was delayed approximately six months as a result of delays in the finalization of the manufacturing process for these substrates. In addition, if we are unable to introduce reliable quality products, we could suffer from reduced orders, higher manufacturing costs, product returns and additional service expenses, all of which could result in lower revenues.

The sales cycle for our GaAs substrates is long and we may incur substantial, non-recoverable expenses or devote significant resources to sales that do not occur as anticipated. We have experienced and continue to experience delays in obtaining purchase orders for GaAs substrates while customers evaluate our substrates. A customer's decision to purchase our GaAs substrates is based upon whether the customer prefers substrates developed using our proprietary VGF technique or substrates developed using the more traditional LEC and HB techniques. The amount of time it takes for a customer to evaluate our GaAs substrates typically ranges from three months to a year or more, depending on the amount of time required to test and qualify substrates from new vendors. Since our substrates are generally incorporated into a customer's products at the design

28

stage, the customer's decision to use our substrates often precedes volume sales, if any, by a significant period. If a customer decides at the design stage not to incorporate our substrates into its products, we may not have another opportunity to sell substrates for those products for many months or even years. Thus, our GaAs substrates typically have a lengthy sales cycle, during which we may expend substantial funds and sales, marketing and management efforts to attract the potential customer. However, there is a risk that these expenditures may not result in sales. Consequently, if sales forecasted from a specific customer for a particular quarter are not delivered in that quarter, we may be unable to compensate for the shortfall, which could materially adversely affect our operating results.

We anticipate that sales of any future products under development will have similar lengthy sales cycles and will, therefore, be subject to risks substantially similar to those inherent in the lengthy sales cycle of our GaAs substrates.

The loss of one or more of our key customers would significantly hurt our operating results. A small number of customers have historically accounted for a substantial portion of our revenues. We expect that a significant portion of our future sales will be due to a limited number of customers. Our top five customers accounted for approximately 35.5%, 34.9% and 39.5% of our revenues in 1996, 1997 and 1998, respectively. Our customers are not obligated to purchase any specified quantity of products or to provide us with binding forecasts of product purchases. In addition, our customers may reduce, delay or cancel orders at any time without any significant penalty.

Our substrates are typically one of many components used in semiconductor devices produced by our customers. Demand for our products is therefore subject to many factors beyond our control, including:

- demand for our customers' products;

- competition faced by our customers in their particular industries;

- the technical, sales and marketing and management capabilities of our customers; and

- the financial and other resources of our customers.

In the past, we have experienced reductions, cancellations and delays in customer orders. If any one of our major customers reduces, cancels or delays orders in the future, our business, financial condition and results of operation could be materially adversely affected.

Intense competition in the market for GaAs substrates could prevent us from increasing revenue and sustaining profitability. The market for GaAs substrates is intensely competitive. In the semi-insulating GaAs substrates market, our principal competitors currently include:

- Freiberger Compound Materials;

- Hitachi Cable;

- Litton Airtron; and

- Sumitomo Electric Industries.

We also compete with manufacturers that produce GaAs substrates for their own use. In addition, we compete with companies, such as IBM, that are actively developing alternative materials to GaAs. As we enter new markets, such as the Ge and InP substrate markets, we expect to face competitive risks similar to those for our GaAs substrates.

Many of our competitors and potential competitors have a number of significant advantages over us, including:

- having been in the business longer than we have;

- more manufacturing experience;

- more established technologies than our VGF technique;

29

- broader name recognition; and

- significantly greater financial, technical and marketing resources.

Our competitors could develop enhancements to the LEC, HB or VGF techniques that are superior to ours in terms of price and performance. Our competitors also could intensify price-based competition, resulting in lower prices and margins. For more information regarding the risks we face from our competitors, see "Business -- Competition."

We derive a significant portion of our revenues from international sales and our ability to sustain and increase our international sales involve significant risks. Our ability to grow will depend in part on the expansion of international sales and operations which have and are expected to constitute a significant portion of our revenues. International sales, excluding Canada, represented 34.1% and 28.8% of our total revenues in 1997 and 1998, respectively. Sales to customers located in Japan and other Asian countries represented 23.5% and 18.7% of our total revenues in 1997 and 1998. Sales to customers in Japan, in particular, accounted for 17.1% and 11.5% of our total revenues in 1997 and 1998, respectively. We expect that sales to customers outside the United States, including device manufacturers located in Japan and other Asian countries who sell their products worldwide, will continue to represent a significant portion of our revenues.

Our dependence on international sales involves a number of risks, including:

- import restrictions and other trade barriers;

- unexpected changes in regulatory requirements;

- longer periods to collect accounts receivable;

- export license requirements;

- political and economic instability (in particular, the current instability of the economies of Japan and other Asian countries); and

- unexpected changes in diplomatic and trade relationships.

Our sales, except for sales by our Japanese subsidiary, are denominated in U.S. dollars. Thus, increases in the value of the dollar could increase the price of our products in non-U.S. markets and make our products more expensive than competitors' products in such markets. For example, doing business in Japan subjects us to fluctuations in the exchange rates between the U.S. dollar and the Japanese yen. In 1996, 1997 and 1998, we incurred foreign exchange losses of $114,000, $186,000 and $24,000, respectively. If we do not effectively manage the risks associated with international sales, our business, financial condition and results of operations could be materially adversely affected. In order to minimize our foreign exchange risk, we have bought foreign exchange contracts to hedge against certain trade accounts receivable in Japanese yen. Because we currently denominate sales in U.S. dollars except in Japan, we do not anticipate that the adoption of the Euro as a functional legal currency of certain European countries will materially affect our business.

If we lose certain key personnel or are unable to hire additional qualified personnel as necessary, we may not be able to successfully manage our business or achieve our objectives. Our success depends to a significant degree upon the continued service of Morris S. Young, Ph.D., AXT's President and Chief Executive Officer, as well as other key management and technical personnel. We neither have long-term employment contracts with, nor key person life insurance on, any of our key personnel. In addition, our management team has limited experience as executive officers of a public company.

We believe our future success will also depend in large part upon our ability to attract and retain highly skilled managerial, engineering, sales and marketing, finance and manufacturing personnel. The competition for these employees is intense, especially in Silicon Valley, and there can be no assurance that we will be successful in attracting and retaining new personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel in the future or delays in hiring required personnel, particularly engineers, could make it difficult for us to manage our business and meet key objectives, such as product introduction, on time.

30

Continued rapid growth may strain our operations. We have recently experienced a period of rapid growth and expansion which has placed, and continues to place, a significant strain on our operations. To accommodate this anticipated growth, we will be required to:

- improve existing and implement new operational and financial systems, procedures and controls;

- hire, train and manage additional qualified personnel;

- effectively manage multiple relationships with our customers, suppliers and other third parties; and

- maintain effective cost controls.

We may not be able to install adequate control systems in an efficient and timely manner, and our current or planned personnel systems, procedures and controls may not be adequate to support our future operations. We are in the process of installing a new management information system; however, the functionality of this new system has not been fully implemented. The difficulties associated with installing and implementing these new systems, procedures and controls may place a significant burden on our management and our internal resources. In addition, international growth will require expansion of our worldwide operations and enhance our communications infrastructure. Any delay in the implementation of such new or enhanced systems, products and controls, or any disruption in the transition to such new or enhanced systems, products and controls, could adversely affect our ability to accurately forecast sales demand, manage manufacturing, purchasing and inventory levels, and record and report financial and management information on a timely and accurate basis. Our inability to manage growth effectively could affect our revenues and adversely impact our profitability.

Our failure and the failure of our key suppliers and customers to be year 2000 compliant could negatively impact our business. The year 2000 computer issue creates a risk for us. If systems do not correctly recognize date information when the year changes to 2000, there could be an adverse impact on our operations. The risk exists in four areas:

- potential warranty or other claims from our customers;

- systems we used to run our business;

- systems used by our suppliers; and

- the potential reduced spending by other companies on networking solutions as a result of significant information systems spending on year 2000 remediation.

We are currently evaluating our exposure in all of these areas.

We are in the process of conducting a comprehensive inventory and evaluation of the information systems used to run our business. We have a number of projects underway to replace older systems that are known to be year 2000 non-compliant. Other systems, which are identified as non-compliant, will be upgraded or replaced. For the year 2000 non-compliance issues identified to date, the cost of remediation is not expected to be material to our operating results. However, if implementation of replacement systems is delayed, or if significant new non-compliance issues are identified, our operating results or financial condition could be materially adversely affected.

We have contacted more than thirty key suppliers to determine if their operations and the products and services they provide are year 2000 compliant. Where practicable, we will attempt to mitigate our risks with respect to the failure of suppliers to be year 2000 ready. However, such failures remain a possibility and could have an adverse impact on our operating results or financial condition.

We believe our current products are year 2000 compliant; however, since all customer situations cannot be anticipated, we may see an increase in warranty and other claims as a result of the year 2000 transition. In addition, litigation regarding year 2000 compliance issues is expected to escalate. For these reasons, the impact of customer claims could have a material adverse impact on our operating results or financial condition.

31

Year 2000 compliance is an issue for virtually all businesses whose computer systems and applications may require significant hardware and software upgrades or modifications. Companies owning and operating such systems may plan to devote a substantial portion of their information systems' spending to fund such upgrades and modifications and divert spending away from networking solutions. Such changes in customers' spending patterns could have a material adverse impact on our business, operating results or financial condition.

We may engage in future acquisitions that we must successfully integrate into our business and that may dilute our stockholders and cause us to assume contingent liabilities. As part of our business strategy, we may in the future review acquisition prospects that would complement our current product offerings, augment our market coverage or enhance our technical capabilities, or that may otherwise offer growth opportunities. In the event of any future acquisitions, we could:

- issue equity securities which would dilute current stockholders' percentage ownership;

- incur substantial debt; or

- assume contingent liabilities.

Such actions by us could materially adversely affect our operating results and/or the price of our common stock.

Any future acquisitions creates risks for us, including:

- difficulties in the assimilation of acquired personnel, operations, technologies or products;

- unanticipated costs associated with the acquisition could materially adversely affect our operating results;

- diversion of management's attention from other business concerns;

- adverse effects on existing business relationships with suppliers and customers;

- risks of entering markets where we have no or limited prior experience;

- potential loss of key employees of acquired organizations; and

- loss of customers that, through product acquisition, now become competitors.

These risks and difficulties could disrupt our ongoing business, distract our management and employees and increase our expenses. We may not be able to successfully integrate any businesses, products, technologies or personnel that we might acquire in the future, and our failure to do so could have a material adverse effect on our business, operating results and financial condition.

We may need additional capital to fund our future operations which may not be available. We believe that our cash balances and cash available from credit facilities and future operations will enable us to meet our working capital requirements for at least the next 12 months. We do not currently anticipate the need for additional capital but if cash from future operations is insufficient, or if cash is used for acquisitions or other currently unanticipated uses, we may need additional capital. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of such securities could result in dilution to existing stockholders.

On December 1, 1998, we raised approximately $11.6 million by issuing variable rate taxable demand revenue bonds series 1998 for:

- the purchase of a commercial building and to finance tenant improvements at 4281 Technology Drive, Fremont, California;

- to refinance an existing loan and to finance tenant improvements on our principal offices; and

- the permanent financing for an existing bank construction loan.

32

These debt securities have rights, preferences and privileges that are senior to holders of common stock, as other debt securities which we may issue in the future would be, and the term of any debt could impose restrictions on our operations. We cannot assure you that if we required additional capital, it will be available on acceptable terms, or at all. If we are unable to obtain additional capital, we may be required to reduce the scope of our planned product development and marketing efforts, which would materially adversely affect our business, financial condition and operating results. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Our executive officers and directors control 21% of our common stock and are able to significantly influence matters requiring stockholder approval. Executive officers, directors and entities affiliated with them, in the aggregate, currently beneficially own approximately 21% of our outstanding common stock. These stockholders, if acting together, are able to significantly influence all matters requiring our stockholder approval, including the election of directors and the approval of mergers or other business combination transactions. This concentration of ownership could delay or prevent a change of control of AXT and could reduce the likelihood of an acquisition of AXT at a premium price.

Provisions in our charter or agreements may delay or prevent a change of control. Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing a merger or acquisition or a change of control or changes in our management. These provisions include, among others:

- the division of the board of directors into three separate classes of three year terms;

- the right of the board to elect the director to fill a space created by the expansion of the board;

- the ability of the board to alter our bylaws;

- authorizing the issuance of up to 2,000,000 shares of "blank check" preferred stock; and

- the requirement that at least 10% of the outstanding shares are needed to call a special meeting of stockholders.

Furthermore, because we are incorporated in Delaware, we are subject to the provisions of section 203 of the Delaware General Corporation Law. These provisions prohibit certain large stockholders, in particular those owning 15% or more of the outstanding voting stock, from consummating a merger or combination with a corporation unless:

- 66 2/3% of the shares of voting stock not owned by this large stockholder approve the merger or combination, or

- the board of directors approves the merger or combination or the transaction which resulted in the large stockholder owning 15% or more of our outstanding voting stock.

Our stock price has been and may continue to be volatile and is dependent on external and internal factors. Our stock has fluctuate significantly since we began trading on the Nasdaq national market. In 1998, our stock price closed as low as $6.00 and as high as $15.50. Various factors could cause the price of our common stock to continue to fluctuate substantially, including:

- actual or anticipated fluctuations in our quarterly or annual operating results;

- changes in expectations as to our future financial performance or changes in financial estimates of securities analysts;

- announcements of technological innovations by us or our competitors;

- new product introduction by us or our competitors;

- large customer orders or order cancellations; and

- the operating and stock price performance of other comparable companies.

33

In addition, the stock market in general has experienced extreme volatility that often has been unrelated to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the trading price of our common stock, regardless of our actual operating performance.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Since many of our Japanese invoices are denominated in yen, we have bought foreign exchange contracts to hedge against certain trade accounts receivable in Japanese yen. As of December 31, 1998, our outstanding commitments with respect to the foreign exchange contracts had a total value of approximately $1.6 million equivalent. Many of the contracts were entered six months prior to the due date and the dates coincide with the receivable terms we have on the invoices. By matching the receivable collection date and contract due date, we attempt to minimize the impact of foreign exchange fluctuation.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of American Xtal Technology, Inc.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, stockholders' equity and cash flows present fairly, in all material respects, the financial position of American Xtal Technology, Inc. and its subsidiaries at December 31, 1997 and 1998, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 1998, in conformity with generally accepted accounting principles. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with generally accepted auditing standards which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above.

AMERICAN XTAL TECHNOLOGY, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES

American Xtal Technology, Inc. (the "Company") was incorporated in California in December 1986 and reincorporated in Delaware in 1998. The Company uses a proprietary vertical gradient freeze ("VGF") technique to produce high-performance compound semiconductor base materials, or substrates, for use in a variety of electronic and opto-electronic applications. The Company manufactures and sells gallium arsenide ("GaAs"), indium phosphide ("InP") and germanium ("Ge") substrates. The Company also has research and development contracts with the U.S. Department of Defense ("DOD") and other third parties for developing GaAs and other substrates.

In May 1998, the Company completed its initial public offering ("IPO") and issued 2,875,000 shares of its common stock at $10.00 per share, including the shares from an over-allotment option. The Company received cash of approximately $25,792,000 net of underwriting discounts, commissions and IPO expenses. Upon the closing of the IPO, all outstanding shares of the Company's then convertible preferred stock were automatically converted into shares of common stock.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles 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 reporting period. Actual results could differ from these estimates.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated.

Foreign Currency Translation

The functional currencies of the Company's Japanese and Chinese subsidiaries are the local currencies. Transaction gains and losses resulting from transactions denominated in currencies other than the US dollar for the Company or in the local currencies for the subsidiaries are included in the results of operations for the year.

The assets and liabilities of the subsidiaries are translated at the rates of exchange on the balance sheet date. Income and expense items are translated at the average rate of exchange for the period. Gains and losses from foreign currency translation are included as a separate component of stockholders' equity.

Revenue Recognition

Product revenues are generally recognized upon shipment. The Company provides an allowance for estimated returns at the time revenue is recognized. Contract revenues are recognized under the percentage of completion method based on costs incurred relative to total contract costs. Costs associated with contract revenues are included in cost of contract revenues. All costs of contract revenues are research and development expenses which are funded by the contract.

Concentration of Credit Risk

The Company manufactures and distributes GaAs, InP and Ge substrates and performs services under research and development contracts. Financial instruments which potentially subject the Company to concentration of credit risk consist primarily of trade accounts receivable. The Company invests primarily in

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

money market accounts and commercial paper instruments. Cash equivalents are maintained with high quality institutions and their composition and maturities are regularly monitored by management.

The Company performs ongoing credit evaluations of its customers' financial condition and limits the amount of credit extended when deemed necessary, but generally does not require collateral. No customer represented greater than 10.0% of product revenues in fiscal years 1996 and 1997, and one customer in 1998, represented 14.2% of product revenues. For fiscal 1996, one government entity represented 91.3% of contract revenues. For fiscal 1997, one government entity and a third party represented 47.4% and 52.6%, respectively, of contract revenues. For fiscal 1998, one government entity represented 100% of contract revenues. No customer accounted for 10% or more of the trade accounts receivable balance as of December 31, 1997, and 1998.

Cash Equivalents

The Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents.

Inventory

Inventory is stated at the lower of cost or market, cost being determined using the weighted average method.

Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation computed using the straight-line method over the estimated economic lives of the assets, generally five years. Leasehold improvements are amortized over the shorter of the estimated useful life or the term of the lease.

Impairment of Long-Lived Assets

Pursuant to Statement of Financial Accounting Standard No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of" ("SFAS 121"), the Company reviews long-lived assets based upon a gross cash flow basis and will reserve for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be fully recoverable. Based on its most recent analysis, the Company believes that there was no impairment of its property, plant and equipment as of December 31, 1998.

Stock-Based Compensation

The Company accounts for stock-based employee compensation arrangements using the intrinsic value method as prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" and related Interpretations thereof. Accordingly, compensation costs for stock options is measured as the excess, if any, of the market price of the Company's stock at the date of grant over the stock option exercise price. In addition, the Company complies with the disclosure provisions of Statement of Financial Accounting Standard No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123").

Income Taxes

The Company accounts for deferred income taxes using the liability method, under which the expected future tax consequences of timing differences between the book and tax basis of assets and liabilities are recognized as deferred tax assets and liabilities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Comprehensive Income

In 1998, the Company adopted Statement of Financial Accounting Standard No.
130 "Reporting Comprehensive Income" ("SFAS 130"). Comprehensive income is defined as the change in equity of a company during a period from transactions and other events and circumstances excluding transactions resulting from investment by owners and distribution to owners. The difference between net income and comprehensive income for the Company relates to foreign currency translation adjustments. Comprehensive income for the years ended December 31, 1996, 1997 and 1998 is disclosed in the Statement of Stockholders' Equity.

Segment Reporting

In 1998, the Company adopted Statement of Financial Accounting Standard No. 131, "Disclosures about Segments of an Enterprise and Related Information" ("SFAS 131"). SFAS 131 requires that companies report separately, in the financial statements, certain financial and descriptive information about operating segment profit or loss, certain specific revenue and expense items, and segment assets. Additionally, companies are required to report information about the revenues derived from their products and service groups, about geographic areas in which the Company earns revenues and holds assets, and about major customers. (See Note 11 for these disclosures).

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 established a new model for accounting for derivatives and hedging activities and supersedes and amends a number of existing accounting standards. SFAS 133 requires that all derivatives be recognized in the balance sheet at their fair market value. In addition, corresponding derivative gains and losses should be either reported in the statement of operations or stockholders' equity, depending on the type of hedging relationship that exists with respect to such derivatives. Adopting the provisions of SFAS 133, which will be effective in fiscal year 2000, is not expected to have a material effect on the Company's consolidated financial statements.

NOTE 3. DEBT

On September 11, 1995, the Company obtained a bank loan of up to $4.5 million to finance the construction of a new commercial building in Fremont, California. The loan, which was due on September 11, 1996, was refinanced with two new loans:

(1) On October 1, 1996, the Company obtained a loan for $3.5 million from a commercial bank. The loan has an interest rate of 8.3% per annum, matures in 2006 and is secured by the land and building. The loan was fully repaid as of December 31, 1998.

(2) On August 15, 1996, the Company obtained a $1.0 million debenture loan from the Bay Area Employment Development Company guaranteed by the U.S. Small Business Administration.

AMERICAN XTAL TECHNOLOGY, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

In November 1996, the Company obtained a $3.0 million line of credit ("LOC") with a bank which expired in April 1998. In March 1998, the Company obtained a $15.0 million LOC which expires in May 1999 to replace the $3.0 million LOC. The $15.0 million LOC is secured by the Company's business assets, excluding equipment. Borrowings under the $15.0 million LOC bear interest at the bank's prime interest rate plus one-half percent. The $15.0 million LOC is subject to certain financial covenants regarding current financial ratios and cash flow requirements which have all been met as of December 31, 1998. At December 31, 1997 and 1998, no amount was outstanding under the LOC.

In May 1997, the Company obtained a bank loan for $1.4 million under the $3.0 million LOC. The loan was to finance construction of manufacturing facility. The loan consisted of two parts: (i) a loan for $750,000 which bears interest at the bank's prime rate plus one percent and is secured by property and (ii) a loan for $690,000 which bears interest at the bank's prime rate plus one-half percent and is secured by the Company's business assets, excluding equipment, which was assumed under the LOC. At the time of building completion, the $750,000 loan is convertible into a new term loan with a maturity of ten years and an interest rate fixed at the nine-year U.S. Treasury Bond yield plus 2.3% and will be secured by the land and building. At December 31, 1997, $106,000 was outstanding at an interest rate of 8.3% per annum. During the year ended December 31, 1998, this construction loan was fully prepaid.

In December 1998, the Company completed the sale of $11.6 million bonds. The bonds, which are secured by a letter of credit from a bank, have a term of 25 years, bear interest at 200 basis points below prime (5.6% at December 31, 1998). Repayment of principal and interest under the bonds is by installment payments on a quarterly basis. The Company has an option to redeem in whole or in part of the bonds during the term of the bonds.

The aggregate future repayments of long-term debt outstanding at December 31, 1998 are $2.8 million in 1999, $2.9 million in 2000, $2.9 million in 2001, $2.6 million in 2002, $1.7 million in 2003 and $10.6 million thereafter. A total interest amount of $5.4 million is included in these aggregate future repayments.

NOTE 4. RESEARCH AND DEVELOPMENT CONTRACTS

In March 1994, the Company was awarded a four-year, $6.1 million contract under the DOD Title III program for the development of GaAs substrates. The Title III contract is comprised of three different contract components: A cost-plus-fixed-fee component totaling $1.2 million, a firm-fixed-price ("FFP") component totaling $4.4 million and a $500,000 component consisting of a bonus award. The bonus award may be earned upon reaching specific contract milestones. Under the FFP component, 10.0% of the cost reimbursement is withheld by the DOD until the completion of the project in May 1998. The amounts relating to this 10.0% withholding were $625,000, $319,000, and $325,000 at December 31, 1996, 1997 and 1998, respectively.

For the years ended December 31, 1996, 1997 and 1998, the Company recognized contract revenues of $1.5 million, $364,000 and $416,000, respectively, under the Title III contract. For the years ended December 31, 1996, 1997 and 1998, the Company incurred costs of $468,000, $211,000 and $87,000, respectively, under the Title III contract. As of December 31, 1998, the Title III contract was completed and the total contract revenue of $6.1 million had been completely recognized.

Certain products were manufactured under the Title III contract and the costs were charged to such contracts. As permitted under the contract, the products were sold to third parties, generating product revenues of $95,000, $0 and $0 for the years ended December 31, 1996, 1997 and 1998, respectively.

In January 1997, the Company was awarded a $1.2 million contract from a third party. The contract was an FFP contract under which the Company produced Ge substrates. The contract was completed in July 1997. For the year ended December 31, 1997, the Company recognized contract revenues of $1.2 million and incurred contract costs of $1.1 million under the contract.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

In May 1997, the Company was awarded a $2.5 million, 30-month contract under the DOD Title III program. In August 1998, the contract was amended such that the work scope was extended and the total contract amount was increased to $3.1 million. The contract is a cost-sharing agreement for the development of InP substrates. Contract revenues are recognized under the percentage of completion method based on total estimated revenue and the proportion of costs incurred relative to total contract costs. For the years ended December 31, 1997 and 1998, the Company recognized contract revenues of $661,000 and $1,238,000, respectively and incurred contract costs of $252,000 and $628,000, respectively under this contract.

The Company has no additional obligations with regards to any of the above research and development contracts.

NOTE 5. FOREIGN EXCHANGE CONTRACTS AND TRANSACTION LOSSES

The Company uses short-term forward exchange contracts for hedging purposes to reduce the effects of adverse foreign exchange rate movements. During the year ended December 31, 1998, the Company bought foreign exchange contracts to hedge against certain trade accounts receivable in Japanese yen. These contracts are accounted for using hedge accounting, under which the change in the fair value of the forward contracts is recognized as part of the related foreign currency transactions as they occur. As of December 31, 1998, the Company's outstanding commitments with respect to the foreign exchange contracts, which were commitments to sell Japanese yen, had a total value of approximately $1.6 million.

Certain Pro Forma Disclosures

In October 1995, SFAS 123 established a fair value based method of accounting for employee stock options. The weighted average grant-date fair value of options granted during the years ended December 31, 1997 and 1998 (no options were granted during the year ended December 31, 1996) was $0.06 and $0.98, respectively. Had compensation cost for the Company's options been determined based on the fair value at the grant dates, as prescribed in SFAS 123, the Company's pro forma net income and net income per share would have been as follows:

                                                    YEARS ENDED DECEMBER 31,

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions used for grants during the years ended December 31, 1997 and 1998 (no options were granted during the year ended December 31, 1996); dividend yield of 0.0% for both periods; risk-free interest rates of 6.1% and 5.2% for options granted during the years ended December 31, 1997 and 1998, respectively; and expected lives of 4.5 and 5.0 years for options granted during the years ended December 31, 1997 and 1998, respectively; and volatility of 0.0% and 75% for the years ended December 31, 1997 and 1998.

Because additional option grants are expected to be made each year, the above pro forma disclosures are not representative of pro forma effects on reported net income for future years.

                                  1

FOURTH:
                                       STOCK

          The Corporation is authorized to issue two classes of stock to be
          designated, respectively, "Preferred Stock" and "Common Stock."
          The total number of shares of Preferred Stock the Corporation
          shall have authority to issue is 2,000,000, $.001 par value per
          share, and the total number of shares of Common Stock the
          Corporation shall have authority to issue is 40,000,000, $0.001
          par value per share. The shares of Preferred Stock shall
          initially be undesignated as to series.

          The Board of Directors is hereby authorized, within the
          limitations and restrictions stated herein, to determine or alter
          the rights, preferences, privileges and restrictions granted to
          or imposed upon a wholly unissued series of Preferred Stock, and
          the number of shares constituting any such series and the
          designation thereof, or any of them; and to increase or decrease
          the number of shares constituting any such series and the
          designation thereof, or any of them; and to increase or decrease
          the number of shares of any series subsequent to the issue of
          shares of that series, but, in respect of decreases, not below
          the number of shares of such series then outstanding. If the
          number of shares of any such series of Preferred Stock shall be
          so decreased, the shares constituting such decrease shall be
          retired and shall not be reissued by the Corporation.

FIFTH:    The following provisions are inserted for the management of the
          business and the conduct of the affairs of the Corporation, and
          for further definition, limitation and regulation of the powers
          of the Corporation and of its directors and stockholders:

     A.   The business and affairs of the Corporation shall be managed by
          or under the direction of the Board of Directors. In addition to
          the powers and authority expressly conferred upon them by statute
          or by this Certificate of Incorporation or the Bylaws of the
          Corporation, the directors are hereby empowered to exercise all
          such powers and do all such acts and things as may be exercised
          or done by the Corporation.

     B.   The directors of the Corporation need not be elected by written
          ballot unless the Bylaws so provide.

     C.   Any action required or permitted to be taken by the stockholders
          of the Corporation must be effected at a duly called annual or
          special meeting of stockholders of the Corporation and may not be
          effected by any consent in writing by such stockholders.

                                  2

     D.   Special meetings of stockholders of the Corporation may be called
          only (1) by the Board of Directors pursuant to a resolution
          adopted by a majority of the total number of authorized directors
          (whether or not there exist any vacancies in previously
          authorized directorships at the time any such resolution is
          presented to the Board for adoption) or (2) by the holders of not
          less than ten percent (10%) of all of the shares entitled to cast
          votes at the meeting.

SIXTH:

     A.   The number of directors shall initially be set at five (5) and,
          thereafter, shall be fixed from time to time exclusively by the
          Board of Directors pursuant to a resolution adopted by a majority
          of the total number of authorized directors (whether or not there
          exist any vacancies in previously authorized directorships at the
          time any such resolution is presented to the Board for adoption).
          The directors shall be divided into three classes with the term
          of office of the first class (Class I) to expire at the first
          annual meeting of the stockholders; the term of office of the
          second class (Class II) to expire at the second annual meeting of
          stockholders; the term of office of the third class (Class III)
          to expire at the third annual meeting of stockholders; and
          thereafter for each such term to expire at each third succeeding
          annual meeting of stockholders after such election. Subject to
          the rights of the holders of any series of Preferred Stock then
          outstanding, a vacancy resulting from the removal of a director
          by the stockholders as provided in Article SIXTH, Section C below
          may be filled at a special meeting of the stockholders held for
          that purpose. All directors shall hold office until the
          expiration of the term for which elected, and until their
          respective successors are elected, except in the case of the
          death, resignation, or removal of any director.

     B.   Subject to the rights of the holders of any series of Preferred
          Stock then outstanding, newly created directorships resulting
          from any increase in the authorized number of directors or any
          vacancies in the Board of Directors resulting from death,
          resignation or other cause (other than removal from office by a
          vote of the stockholders) may be filled only by a majority vote
          of the directors then in office, though less than a quorum, and
          directors so chosen shall hold office for a term expiring at the
          next annual meeting of stockholders at which the term of office
          of the class to which they have been elected expires, and until
          their respective successors are elected, except in the case of
          the death, resignation, or removal of any director. No decrease
          in the number of directors constituting the Board of Directors
          shall shorten the term of any incumbent director.

     C.   Subject to the rights of the holders of any series of Preferred
          Stock then outstanding, any directors, or the entire Board of
          Directors, may be

                                  3

          removed from office at any time, with or without cause, but only
          by the affirmative vote of the holders of at least a majority of
          the voting power of all of the then outstanding shares of capital
          stock of the Corporation entitled to vote generally in the
          election of directors, voting together as a single class.
          Vacancies in the Board of Directors resulting from such removal
          may be filled by a majority of the directors then in office,
          though less than a quorum, or by the stockholders as provided in
          Article SIXTH, Section A above. Directors so chosen shall hold
          office for a term expiring at the next annual meeting of
          stockholders at which the term of office of the class to which
          they have been elected expires, and until their respective
          successors are elected, except in the case of the death,
          resignation, or removal of any director.

SEVENTH:  The Board of Directors is expressly empowered to adopt, amend or
          repeal Bylaws of the Corporation. Any adoption, amendment or
          repeal of Bylaws of the Corporation by the Board of Directors
          shall require the approval of a majority of the total number of
          authorized directors (whether or not there exist any vacancies in
          previously authorized directorships at the time any resolution
          providing for adoption, amendment or repeal is presented to the
          Board). The stockholders shall also have power to adopt, amend or
          repeal the Bylaws of the Corporation. Any adoption, amendment or
          repeal of Bylaws of the Corporation by the stockholders shall
          require, in addition to any vote of the holders of any class or
          series of stock of the Corporation required by law or by this
          Certificate of Incorporation, the affirmative vote of the holders
          of at least sixty-six and two-thirds percent (66-2/3%) of the
          voting power of all of the then outstanding shares of the capital
          stock of the Corporation entitled to vote generally in the
          election of directors, voting together as a single class.

EIGHTH:   A director of the Corporation shall not be personally liable to
          the Corporation or its stockholders for monetary damages for
          breach of fiduciary duty as a director, except for liability (i)
          for any breach of the director's duty of loyalty to the
          Corporation or its stockholders, (ii) for acts or omissions not
          in good faith or which involved intentional misconduct or a
          knowing violation of law, (iii) under Section 174 of the Delaware
          General Corporation Law, or (iv) for any transaction from which
          the director derived an improper personal benefit.

          If the Delaware General Corporation Law is hereafter amended to
          authorize the further elimination or limitation of the liability
          of a director, then the liability of a director of the
          Corporation shall be eliminated or limited to the fullest extent
          permitted by the Delaware General Corporation Law, as so amended.

                                  4

          Any repeal or modification of the foregoing provisions of this
          Article EIGHTH by the stockholders of the Corporation shall not
          adversely affect any right or protection of a director of the
          Corporation existing at the time of such repeal or modification.

NINTH:    The Corporation reserves the right to amend or repeal any
          provision contained in this Certificate of Incorporation in the
          manner prescribed by the laws of the State of Delaware and all
          rights conferred upon stockholders are granted subject to this
          reservation; provided, however, that, notwithstanding any other
          provision of this Certificate of Incorporation or any provision
          of law which might otherwise permit a lesser vote or no vote, but
          in addition to any vote of the holders of any class or series of
          the stock of this Corporation required by law or by this
          Certificate of Incorporation, the affirmative vote of the holders
          of at least 66-2/3% of the voting power of all of the then
          outstanding shares of the capital stock of the Corporation
          entitled to vote generally in the election of directors, voting
          together as a single class, shall be required to amend or repeal
          this Article NINTH, Article FIFTH, Article SIXTH, Article SEVENTH
          or Article EIGHTH.

The Bank shall maintain in accordance with its usual practice an account or accounts evidencing the obligation of the Borrower resulting from each drawing under the Letter of Credit. In any legal action or proceeding in respect of this Agreement, the entries made in such account or accounts shall, in the absence of error in calculation, be conclusive evidence of the existence and amounts of the obligations of the Borrower therein recorded.

SECTION 2.8 Obligations Absolute. The payment or reimbursement obligations of the Borrower under this Agreement shall be unconditional and irrevocable, and shall be paid strictly in accordance with and subject to the terms and conditions of this Agreement under all circumstances, including, without limitation, the following circumstances:

(a) any lack of validity or enforceability of any of the Related Documents;

(b) any amendment or waiver of or any consent to departure from all or any of the Related Documents;

(c) the existence of any claim, set-off, defense, or other right which the Borrower may have at any time against the Trustee or any other beneficiary, or any transferee, of the Letter of Credit (or any persons or entities for whom the Trustee, any such beneficiary, or any such transferee may be acting), the Bank, or any other person or entity, whether in connection with this Agreement, the transactions contemplated herein or in the Related Documents, or any unrelated transaction;

(d) any statement or any other document presented under the Letter of Credit proving to be forged, fraudulent, or invalid in any respect or any statement therein being untrue or inaccurate in any respect;

SECTION 2.9 Default Interest. If an Event of Default has occurred and is continuing, the Obligations shall bear interest, payable on demand, at the Reference Rate plus 5% per annum (such sum, the "Default Rate") until such required payment plus interest thereon has been paid; provided, however, that nothing contained in this Section 2.9 shall be construed to waive or limit any of the rights and remedies of the Bank with respect to such nonpayment under this Agreement or the Related Documents.

SECTION 2.10 Tranches of Debt. The obligations owing at any time by the Borrower to the Bank shall, solely for the purpose of identifying which portions of the Obligations are secured by specific items of Collateral, be divided into the following tranches ("Tranches"):

Tranche                      Maximum Principal Amount of Tranche
-------                      -----------------------------------
A                            $4,900,000
B                            $5,440,000
C                            All remaining indebtedness and Obligations
                             owing hereunder or under the Related
                             Agreements at any time

Any payments received by the Bank hereunder shall be applied to the Obligations payable under each of the Tranches on a pro rata basis. As the maximum amount of the Letter of Credit is reduced in connection with each partial redemption of the Bonds required under Section 5.l(f) hereof, the reduction of the maximum principal amount of Obligations payable under each of the Tranches shall be as set forth in Schedule I attached hereto.

SECTION 2.11 Repayment of Bank Debt. The Borrower hereby agrees that, simultaneously with its issuance of the Bonds and the Bank's issuance of the Letter of Credit, a portion of the proceeds derived from the sale of the Bonds shall be paid directly to the Bank for the purpose of paying in full all indebtedness owing under (a) that certain promissory note dated as of October 1, 1996, in favor of Commercial Bank of Fremont (now the Bank) in the original principal amount of $3,537,355.00 (the "Fremont Note"), and (b) that certain promissory note dated as of May 27, 1997, in favor of U.S. Bank (now the Bank) in the original principal amount of $750,000.00 (the "USB Note"). The amount of principal and interest owing under (i) the Fremont Note is $3,481,838.90 of principal and accrued and unpaid interest, and (ii) the USB Note is $709,117.68 of principal and accrued and unpaid interest. (The amounts listed in the preceding clauses (i) and (ii) represent principal and accrued and unpaid interest outstanding under the Fremont Note and the USB Note, respectively, as of December 5, 1998. To the extent that the Fremont Note and the USB Note are repaid prior to December 5, 1998, as is currently anticipated by the parties, the Bank will promptly refund to the Borrower the amount of any overpayment.)

The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 9.4 Indemnification.

(a) The Borrower hereby indemnifies and holds the Bank harmless from and against any and all claims, damages, losses, liabilities, costs, or expenses which the Bank may incur or which may be claimed against the Bank by reason of
(i) any conditions, occupancy, use, possession, conduct or management of, or work done in or about, or from the planning, design, acquisition, installation, or construction of the Property, or any part thereof, or (ii) carrying out of any of the transactions contemplated by this Agreement and the Related Documents, including, but not limited to, any certifications or representations made by the Borrower in connection therewith; provided, however, that the Borrower shall not be obligated to indemnify the Bank for

13

claims, damages, losses, liabilities, costs and expenses resulting solely from the Bank's gross negligence or willful misconduct.

(b) Nothing in this Section 9.4 is intended to limit the Borrower's obligations contained in Article II hereof. Without prejudice to the survival of any other obligation of the Borrower hereunder, the indemnities and obligations of the Borrower contained in this Section 9.4 shall survive the payment in full of amounts payable pursuant to Article II hereof and the termination of the Letter of Credit.

(c) In the event that any applicable law, order, regulation, treaty or directive issued by any central bank or other governmental authority, agency or instrumentality or any governmental or judicial interpretation or application thereof, or compliance by the Bank with any request or directive (whether or not having the force of law) issued by any central bank or other governmental authority, agency or instrumentality:

(1) does or shall subject the Bank to any tax of any kind whatsoever with respect to this Agreement or the Letter of Credit, or change the basis of taxation of payments to the Bank of any reimbursement, fee, interest or any other amount payable hereunder (except for change in the rate of tax on the overall net income of the Bank);

(2) does or shall impose, modify or hold applicable any reserve, capital requirement, special deposit, compulsory loan or similar requirements against assets held by, or deposits or other liabilities in or for the account of, advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of the Bank which is not otherwise included in the determination of interest payable on the Obligations; or

(3) does or shall impose on the Bank any other condition;

and the result of any of the foregoing is to increase the cost to the Bank of issuing, renewing or maintaining the Letter of Credit or to reduce any amount receivable in respect thereof or the rate of return on the capital of the Bank or any corporation controlling the Bank, then, in any such case, the Borrower agrees to promptly pay to the Bank, upon its written demand, any additional amounts necessary to compensate the Bank for such additional cost or reduced amounts receivable or rate of return as determined by the Bank with respect to this Agreement or the Letter of Credit. If the Bank becomes entitled to claim any additional amounts pursuant to this subparagraph (c), it shall promptly notify the Borrower of the event by reason of which it has become so entitled. A certificate as to any additional amounts payable pursuant to the foregoing sentence containing the calculation thereof in reasonable detail submitted by the Bank to the Borrower shall be conclusive in the absence of manifest error. The provisions hereof shall survive the termination of this Agreement and payment of the Obligations and all other amounts payable hereunder.

SECTION 9.5 Liability of the Bank. As between the Borrower and the Bank, the Borrower assumes all risks of the acts or omissions of the Trustee and any other beneficiary or transferee of the Letter of Credit with respect to its use of the Letter of Credit.

14

made of the Letter of Credit or any acts or omissions of the Trustee and any other beneficiary or transferee in connection therewith; (b) the validity, sufficiency, or genuineness of documents presented to the Bank, or of any endorsements thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged; (c) payment by the Bank against presentation of documents which do not comply with the terms of the Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit; or (d) any damage, deficiency, loss, cost, or expense arising out of any action, claim, or other circumstance of any nature whatsoever relating to the payment or failure to make payment under the Letter of Credit, except that the Borrower shall have a claim against the Bank, and the Bank shall be liable to the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (i) the Bank's willful misconduct or gross negligence in determining whether documents presented under the Letter of Credit comply with the terms of the Letter of Credit or (ii) the Bank's willful failure to make lawful payment under the Letter of Credit after the presentation to it by the Trustee or a successor trustee under the Indenture of a draft and certificate strictly complying with the terms and conditions of the Letter of Credit. In furtherance and not in limitation of the foregoing, the Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, unless acceptance of such documents after receipt of such notice constitutes gross negligence or willful misconduct.

SECTION 9.6 Costs, Expenses, and Taxes. The Borrower agrees to pay immediately following demand therefor all reasonable costs and expenses in connection with the preparation, execution, delivery, filing, and recording of this Agreement, the Bank Documents, and any other documents which may be delivered in connection with this Agreement, including, without limitation, the reasonable fees and out-of-pocket expenses of counsel for the Bank with respect thereto and with respect to advising the Bank as to its rights and responsibilities under this Agreement and the Related Documents, the costs of substituting a letter of credit or other credit enhancement, and any and all other costs, expenses, fees, liabilities, and claims of any nature whatsoever (including reasonable counsel fees and expenses) arising out of or in connection with (i) the enforcement of this Agreement, the Related Documents and such other documents as may be delivered in connection therewith, (ii) any action or proceeding relating to a court order, injunction, or other process or decree restraining or seeking to restrain the Bank from paying any amount under the Letter of Credit and (iii) amending or supplementing this Agreement or the Related Documents for any purpose. In addition, the Borrower shall pay any and all stamp and other taxes and fees payable or determined to be payable in connection with the execution, delivery, filing, and recording of all instruments required by the Bank to be filed in connection with the transactions contemplated hereby, and, to the extent permitted by law, agrees to hold the Bank harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes and fees. The Borrower shall be furnished with copies of bills relating to the foregoing upon request.

SECTION 9.7 Participations, Etc. The Borrower acknowledges that the Bank may elect to sell, assign and otherwise transfer to other persons (each, a "Transferee") all or portions of, and participations in, the Bank's interests hereunder and under the Related Documents from time to time and expressly agrees that each Transferee shall be entitled to the rights of the

15

"Bank" hereunder. For purposes of this Section 9.7, the Bank may disclose to a potential or actual Transferee any and all information supplied to the Bank by or on behalf of the Borrower. The Borrower agrees to execute and deliver to the Bank such documents, instruments and agreements, including, without limitation, amendments to the Related Documents, deemed necessary or desirable by the Bank to effect such transfers.

SECTION 9.8 Binding Effect.

SECTION 9.10 Severability. Any provision of this Agreement which is prohibited, unenforceable, or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability, or nonauthorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

SECTION 9.11 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of California (without giving effect to principles of conflict of laws).

SECTION 9.12 Headings. Section headings in this Agreement shall have no substantive or interpretative effect, are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

SECTION 9.13 Counterparts. This Agreement may be executed in several counterparts, each of which shall be regarded as the original and all of which shall constitute one and the same Agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed and delivered by their respective officers thereunto duly authorized as of the date first above written.

Fremont, California 94538

Dear Mr. Atwood:

Dain Rauscher Incorporated (the "Underwriter") hereby offers to enter into this Bond Purchase Contract (the "Purchase Contract") with American Xtal Technology, Inc. (the "Issuer"). The offer is hereby made subject to acceptance by the Issuer (by the execution and delivery of this Purchase Contract to the Underwriter) on or before 8:00 a.m., Pacific Standard Time, on December 1, 1998 and upon such acceptance, this Purchase Contract shall be in full force and effect in accordance with its terms and shall be binding upon the Issuer and the Underwriter. Capitalized terms used herein and not otherwise defined have the meaning set forth in the Official Statement hereinafter defined.

The Issuer is entering into this Purchase Contract in order to induce the Underwriter to enter into this Purchase Contract and to purchase the $11,615,000 aggregate principal amount of American Xtal Technology, Inc. Variable Rate Taxable Demand Revenue Bonds Series 1998 (Xtal Project) (the "Bonds") on the terms set forth herein. The Issuer, by its acceptance of the offer made herein, requests the Underwriter to purchase the Bonds.

The Bonds are issued pursuant to an Indenture, dated as of December 1, 1998 (the "Indenture"), by and between the Issuer and Harris Trust Company of California, as trustee (the "Trustee"), in the form heretofore delivered to us authorizing the Bonds.

The Issuer will enter into a Letter of Credit and Reimbursement Agreement dated December 1, 1998 (the "Reimbursement Agreement") with U.S. Bank National Association (the "Bank"), pursuant to which the Bank will issue on or before the Date of Delivery of the Bonds (the "Bond Issuance Date") to the Trustee for the account of the Issuer, an irrevocable direct-pay letter of credit (the "Letter of Credit"), which will permit the Trustee to draw an amount equal to the principal and up to 96 days' interest on the Bonds at a maximum rate of twelve percent (12%) per annum. The Reimbursement Agreement will provide for reimbursement by the Issuer to the Bank in the event of drawings under the Letter of Credit. The Indenture, this Purchase Contract and the Reimbursement Agreement are herein referred to as the "Program Documents." References in this Purchase Contract to the authorization, execution and delivery of and performance under the Program Documents by a person or an entity shall be deemed to refer only to those Program Documents to which such person or entity is a party.

The Issuer's obligation under the Reimbursement Agreement will be secured by a first lien and third lien Deed of Trust, Security Agreement, Assignment of Leases and Rents and Fixture Filing, a Security Agreement and other security as set forth in the Reimbursement Agreement.

SECTION 1. PURCHASE AND PURCHASE PRICE. Under the terms and conditions and in reliance upon the representations, warranties and agreements set forth herein, the Issuer agrees to execute and deliver $11,615,000 aggregate principal amount of the Bonds and the Underwriter agrees to purchase all (but not less than all) of said Bonds at an aggregate Purchase Price of par.

1

The Bonds will bear interest as provided in the Indenture.

SECTION 2. OFFICIAL STATEMENT. The Issuer shall deliver or cause to be delivered to the Underwriter, promptly after acceptance hereof and prior to the Closing, copies of the Official Statement dated November 23, 1998, relating to the Bonds and approved for distribution by the Issuer (which Official Statement, including the cover page and all appendices, exhibits, reports and statements included therein or attached thereto being herein called the "Official Statement"), signed on behalf of the Issuer by a duly authorized officer of the Issuer.

The Issuer hereby ratifies, approves and authorizes the use by the Underwriter, prior to the date hereof, in connection with the offer and sale of the Bonds, of the Program Documents, the Letter of Credit and all information contained herein and therein of all other documents, certificates or statements furnished by the Issuer to the Underwriter in connection with the transactions contemplated by this Purchase Contract. The Underwriter agrees that it will not confirm the sale of any Bonds unless the settlement of such sale is accompanied by or preceded by the delivery of a copy of the final Official Statement.

In the event that the Bonds, or the remarketing of the Bonds, should become subject to the continuing disclosure requirements of Rule 15c2-12 under the Securities Exchange Act of 1934 (the "Rule"), the Issuer will furnish to the Underwriter all information reasonably required by the Underwriter to comply with the Rule. To the extent necessary to comply with the Rule, if applicable, the Issuer will notify the Underwriter if it becomes aware of any fact or event which might or would cause the Official Statement, as then supplemented or amended, to contain any untrue statement of a material fact or to omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Issuer will cooperate with the Underwriter by furnishing such information as is reasonably required to amend or supplement the Official Statement, and prepare or file any other papers, in compliance with the Rule.

SECTION 3. CLOSING; BONDS. At 8:00 a.m., Pacific Standard Time, December 1, 1998, or at such other time or on such earlier or later date as the Underwriter and the Issuer mutually agree upon, the Issuer will deliver or cause to be delivered to the Underwriter the Bonds in definitive form, duly executed, and authenticated together with the other documents hereinabove mentioned, and the Underwriter will accept such delivery and pay the Purchase Price of the Bonds set forth in Section 1 hereof in federal funds payable to the order of the Trustee for the account of the Issuer. Delivery and payment shall be simultaneously, as aforesaid, made at such place in New York, New York as the Underwriter shall designate or in such other city as the Underwriter and the Issuer mutually agree upon. This payment and delivery shall be called the "Closing." The Bonds shall be in fully registered form, registered in such names as the Underwriter shall submit to the Trustee prior to the Closing and shall be in denominations of One Hundred Thousand Dollars ($100,000) or any integral multiple of $5,000 above such amount, except as otherwise provided in the Indenture. The Bonds shall be made available to the Underwriter for checking at least one (1) Business Day prior to the Closing. Notwithstanding the foregoing and any other references in this Purchase Contract to delivery of Bonds, or similar statements, the Bonds are registered in the name of Cede & Co. as nominee of the Depository Trust Company ("DTC") and DTC procedures will be followed and take precedence over any conflicting procedures or provisions.

SECTION 4. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE ISSUER. The Issuer represents warrants and covenants to the Underwriter that:

(a) The Issuer is a Delaware corporation and is duly qualified to transact business in California. The Issuer has full power and authority to own its property (including, without limitation, the Project), to carry on its business as presently being conducted and as contemplated to be conducted by the Program Documents and to execute, deliver and perform its obligations under the Program Documents.

(c) The execution, delivery and performance of the Program Documents and the taking of any and all other actions and the execution, delivery and performance of all such documents as may be required of it pursuant to the provisions of the Program Documents including, without limitation, the authorization of the use by the Underwriter of the Official Statement in connection with the offering, sale and distribution of the Bonds, have been duly authorized by the Issuer.

(d) This Purchase Contract has been duly executed and delivered by the Issuer and when executed and delivered by the other parties hereto will constitute a legal, valid and binding obligation of the Issuer, enforceable in accordance with its terms, except as limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting the rights of creditors generally. Upon the execution and delivery of the Program Documents by the Issuer and the other parties thereto, the Program Documents will constitute legal, valid and binding obligations of the Issuer, enforceable in accordance with their respective terms, except as limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors' rights generally.

(e) If at any time the Issuer becomes aware that any event shall have occurred of which the Issuer believes it has unique knowledge not available to the Underwriter and which might cause the Official Statement to contain any untrue statement of material fact or omit to state any fact necessary to make the statements therein not misleading in any material respect, the Issuer shall notify the Underwriter. In addition, the Issuer shall promptly advise the Underwriter of the institution of any action, suit, proceeding, inquiry or investigation of which it has any knowledge seeking to prohibit, restrain or otherwise affect the use of the Official Statement in connection with the offering, sale or distribution of the Bonds. The Issuer promptly shall furnish the Underwriter any information concerning the Issuer which the Underwriter might reasonably request in connection with any amendment of or supplement to the Official Statement.

(f) The execution, delivery and performance of the Program Documents and the consummation of the transactions contemplated thereby will not conflict with, or constitute a breach of, or default under any indenture, mortgage, deed of trust, lease, note, commitment, agreement or other instrument or obligation to which the Issuer is a party or by which the Issuer or any of its respective properties is bound, or under any law, rule, regulation, judgment, order or decree to which the Issuer or any of its respective properties are bound which breach might have a material adverse effect on the ability of the Issuer to perform under the Program Documents. The Issuer is not now and never has been in default under any order or decree of any court or any order, regulation or demand of any federal, state, municipal or governmental agency or any document, instrument or commitment to which the Issuer is subject or in the payment of the principal of, or premium or interest on, or otherwise in default with respect to, any Bonds, notes or other obligations which it has issued, assumed or guaranteed, directly or indirectly, as to payment of principal, premium or interest.

(g) To the Issuer's knowledge, there is no action, suit, proceeding, inquiry or investigation by or before any court, governmental agency, public board or body pending, or to the knowledge of the Issuer, threatened against the Issuer (nor, to the best of its knowledge, is there any basis therefore), which (i) affects or seeks to prohibit, restrain or enjoin the issuance, sale or delivery of the Bonds or the issuance of the Letter of Credit or the use of the Official Statement or the execution and delivery of the Program Documents or (ii) affects or questions the validity or the enforceability of the Bonds, (iii) questions the completeness or accuracy of the Official Statement or (iv) questions the power or authority of the Issuer to carry out the transactions contemplated by the Program Documents or the power of the Issuer to acquire, own, construct, equip, operate or lease the Project.

(h) To the Issuer's knowledge, it has made all filings with and received all approvals, consents and orders of any governmental authority, legislative body, board, agency or commission having jurisdiction which are necessary to permit the Issuer to perform its obligations under the Program Documents, to carry out the transactions contemplated by the Program Documents and to acquire, own, construct, equip, operate and lease the Project.

3

(i) Any certificate signed for the Issuer by an authorized representative thereof and delivered to the Underwriter or the Issuer in connection with the transactions contemplated by the Program Documents shall be deemed to be a representation and warranty by the Issuer to the Underwriter as to the statements therein.

SECTION 8. INDEMNIFICATION.

(a) The Issuer shall indemnify, protect, defend and hold harmless the Underwriter and each person who controls the Underwriter, within the meaning of the Securities Act of 1933, as amended, or the Securities Act of 1934, as amended (collectively, the "Securities Acts"), against any and all losses, claims, damages, liabilities, costs and expenses (including, without limitation, fees and disbursements of counsel and other expenses) incurred by them or any of them in connection with defending any loss, claim, damage, liability or any suit, action or proceeding, joint or several, to which they or any of them may become subject under the Securities Acts, or any other federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages, liabilities, costs and expenses (or any suit, action or proceeding in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Official Statement or in any amendment or supplement thereto approved by the Issuer (which approval shall not be unreasonably withheld) or arise out of or are based upon the omission or alleged omission to state therein a fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Issuer shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in that particular part of the Official Statement, or any amendment thereof or supplement thereto, under the captions "THE BOOK-ENTRY ONLY SYSTEM" or "THE BANK." Notwithstanding the foregoing, this indemnity shall not cover any losses, claims, damages or liabilities caused solely by the gross negligence of the indemnified party or solely by breach of this agreement by the indemnified party.

(b) The Underwriter shall indemnify, protect, defend and hold harmless the Issuer against any and all losses, claims, damages, liabilities, costs and expenses (including, without limitation, fees and disbursements of counsel and other expenses) incurred by them or any of them in connection with defending any loss, claim, damage, liability or any suit, action or proceeding, joint or several, to which they or any of them may become subject under the Securities Acts, or any other federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages, liabilities, costs and expenses (or any suit, action or proceeding in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the "THE UNDERWRITER" caption of the Official Statement or in the "THE UNDERWRITER" caption of any amendment or supplement thereto approved by the Issuer (which approval shall not be unreasonably withheld), or arise out of or are based upon the omission or alleged omission to state therein a fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, this indemnity shall not cover any losses, claims, damages or liabilities caused solely by the negligence of the indemnified party or solely by breach of this agreement by the indemnified party.

(c) Promptly after receipt by any party entitled to indemnification under this Section 8 of notice of the commencement of any suit, action or proceeding, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under this
Section 8 or from any liability under this Section 8 unless the failure to provide notice prejudices the defense of such suit, action or proceeding. In case any such action is brought against any indemnified party, and it notifies the indemnifying party, the indemnifying party shall be entitled to participate in, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to

8

assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party shall not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with defense thereof unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, approved by the Underwriter, the Issuer in the case of the subparagraph (a), representing the indemnified parties under the subparagraph (a) who are parties to such action),
(ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii).

(d) The Issuer shall not be liable for any settlement of any such action effected without its consent by any indemnified party, but if settled with the consent of the Issuer or if there be a final judgment for the plaintiff in any such action against the Issuer or any indemnified party, with or without the consent of the Issuer, then the Issuer agrees to indemnify and hold harmless such indemnified party to the extent provided herein.

SECTION 9. EXPENSES. Whether or not the sale of the Bonds by the Issuer to the Underwriter is consummated, the Underwriter shall be under no obligation to pay any costs or expenses incident to the performance of the obligations of the Issuer hereunder. All costs and expenses to effect the authorization, preparation (including word processing and printing costs), issuance, sale and delivery, as the case may be, of the Official Statement (together with any amendments or supplements thereof), the Bonds, the Program Documents, the Letter of Credit, any rating agency fees, Trustee's fees and expenses, Trustee's counsel fees and disbursements, financial consultant fees and disbursements, the fees and disbursements of Bond Counsel, fees and disbursements of counsel for the Issuer and the amount to be paid to the Underwriter pursuant to Section 1 of this Purchase Contract, shall be paid out of the sources provided therefor in the Indenture, or if the Bonds are not delivered by the Issuer to the Underwriter, such costs and expenses shall be paid by the Issuer.

In the event that, for any reason, the Issuer fails to deliver the Bonds as provided herein by 10:00 a.m. Pacific Standard time, on December 1, 1998, the Issuer will pay to the Underwriter any losses resulting from the Underwriter being required to hold Bonds prior to delivery to ultimate purchasers thereof. This preceding sentence shall not be construed as a waiver of any condition to the Underwriter's obligations under the Purchase Contract.

SECTION 10. SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS. The respective agreements, covenants, representations, warranties and other statements of the Issuer and each of their respective officials or officers set forth in or made pursuant to this Purchase Contract shall remain in full force and effect, regardless of any investigation, or statements as to the results thereof, made by or on behalf of the Underwriter and will survive delivery of and payment for the Bonds.

Any notice or other communication hereunder shall be in writing, and, if sent to the Underwriter, will be mailed, delivered or telecopied and confirmed to the Underwriter care of Dain Rauscher Incorporated, One Market Plaza, 1100 Steuart Street Tower, San Francisco, California 94105, and if sent to the Issuer shall be mailed, delivered, or telecopied and confirmed at its address respectively set forth above.

SECTION 12. GOVERNING LAW. This Purchase Contract shall be governed by and construed in accordance with the laws of the State of California, without giving effect to the principles of conflict of laws in the State of California.

SECTION 13. COUNTERPARTS. This Purchase Contract may be executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument.

requested by the Remarketing Agent which the Remarketing Agent or its counsel may consider necessary or desirable to register the sale of the Bonds by the Remarketing Agent under any Federal or state securities law or to qualify the Indenture under the Trust Indenture Act of 1939, as amended, and will provide the Remarketing Agent such officers' certificates, counsel opinions, accountants' letters and other documents as may be customary in similar transactions. If the Issuer does not perform its obligations under this Section, the Remarketing Agent may immediately cease remarketing efforts.

(b) The Issuer has authorized the use by the Remarketing Agent of the Official Statement in connection with the remarketing of Bonds. For purposes of this Remarketing Agreement, the Official Statement and any other documents provided to the Remarketing Agent pursuant to paragraph (a) of this Section shall be considered to be the Disclosure Statement.

(b) The execution and delivery of this Remarketing Agreement and the consummation of the transactions contemplated herein and in the Indenture will not conflict with or constitute on the part of the Remarketing Agent a breach of or a default under its charter documents, its by-laws, or any statute, indenture, mortgage, deed of trust, lease, note agreement or other agreement or instrument to which the Remarketing Agent is a party or by which it or its properties are bound, or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Remarketing Agent or any of its activities or properties.

(f) This Remarketing Agreement and any other instrument or agreement relating thereto to which it is a party which have been executed by the Remarketing Agent in connection with the consummation of the transactions contemplated hereby and by the Official Statement will constitute its legal, valid and binding obligations, enforceable against it in accordance with their respective terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws, or equitable principles relating to or limiting creditors' rights generally.

(g) The Remarketing Agent will use its best efforts to remarket the Bonds pursuant to the Indenture.

SECTION 5. REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS OF THE ISSUER. The Issuer, by its acceptance hereof, represents, warrants, covenants, and agrees with the Remarketing Agent as follows:

2

(a) It has full power and authority to take all actions required or permitted to be taken by it or under, and to perform and observe the covenants and agreements on its part contained in, the Program Documents (as that term is defined in the Bond Purchase Contract) and any other instrument or agreement relating thereto to which it is a party (collectively, the "Closing Documents").

(b) It has, on or before the date hereof, duly taken all action necessary to be taken by it prior to such date for: (i) the execution, delivery and performance of the Closing Documents, which have been executed by the Issuer in connection with the transactions contemplated thereby, and (ii) the carrying out, giving effect to, consummation and performance of the transactions and obligations contemplated hereby and by the Official Statement; provided that no representation is made with respect to compliance with the securities or Blue Sky laws of the various states of the United States.

(c) The Closing Documents which have been executed by the Issuer in connection with the consummation of the transactions contemplated hereby and by the Official Statement will constitute its legal, valid and binding obligations, enforceable against it in accordance with their respective terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws, or equitable principles relating to or limiting creditors' rights generally.

(d) The execution and delivery of the Closing Documents which have been executed in connection with the consummation of the transactions contemplated hereby and by the Official Statement, the compliance with the terms, conditions or provisions thereof, and the consummation of the transactions therein contemplated do not and will not violate any law, regulation, order, writ, injunction or decree of any court or governmental body or result in a breach of any of the terms, conditions or provisions of, or constitute a default under, or result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the properties or assets of the Issuer pursuant to any mortgage, resolution, agreement or instrument to which the Issuer is a party or by which it or any of its properties is bound other than those provided for in the Closing Documents or contemplated by the parties.

(e) All authorizations, consents and approvals of, notices to, registrations or filings with, or actions in respect of any governmental body, agency or other instrumentality or court required in connection with the execution, delivery and performance by the Issuer of the Closing Documents and which have been executed in connection with the consummation of the transactions contemplated hereby and by the Official Statement have been obtained, given or taken and are in full force and effect; provided that no representation is made with respect to compliance with the securities or Blue Sky laws of the various states of the United States.

(f) To the knowledge of the Issuer, other than as described in the Official Statement, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board or body pending or threatened against or affecting him wherein an unfavorable decision, ruling or finding is likely to have a materially adverse effect on the financial condition or solvency of the Issuer or the ability of the Issuer to perform its obligations under the Closing Documents or any other agreement or instrument to which it is a party and which is used or contemplated for use in consummation of the transactions contemplated hereby or by the Official Statement.

(g) The Issuer will cooperate with the Remarketing Agent in the qualification of the Bonds for offering and sale and the determination of the eligibility of the Bonds for investment under the laws of such jurisdictions as the Remarketing Agent shall designate and will use its best efforts to continue any such qualifications in effect so long as required for the distribution of all the Bonds by the Remarketing Agent; provided that the Issuer shall not be required to incur any expense, consent to service of process in any such jurisdiction or qualify to do business in any jurisdiction where it is not now so subject.

SECTION 6. CONDITIONS TO REMARKETING AGENT'S OBLIGATIONS. The obligations of the Remarketing Agent under this Remarketing Agreement have been undertaken in reliance on, and shall be subject to, the due performance by the Issuer of its obligations and agreements to be performed hereunder and to the accuracy of and compliance with the representations, warranties, covenants and agreements of the Issuer contained herein, on and as of the Date of Delivery of this Remarketing Agreement. The obligations of the Remarketing Agent on and as of

3

each date on which Bonds are to be offered and sold pursuant to this Remarketing Agreement are also subject to the following further conditions:

(a) Each of the Closing Documents shall be in full force and effect and shall not have been amended, modified or supplemented in any way which would materially adversely affect the Bonds, except as may have been agreed to in writing by the Remarketing Agent, and there shall be in full force and effect such additional resolutions, agreements, certificates and opinions, which resolutions, agreements, certificates and opinions shall be satisfactory in form and substance to the Remarketing Agent; and

(b) No Event of Default (as such term is defined in any of the Closing Documents) shall have occurred and be continuing and no event shall have occurred and be continuing which, with the passage of time or giving of notice or both, would constitute such an Event of Default.

SECTION 7. INDEMNIFICATION AND CONTRIBUTION.

(a) The Issuer will indemnify, protect, defend and hold harmless the Remarketing Agent, each of its directors, officers, agents and employees and each person who controls the Remarketing Agent within the meaning of Section 15 of the Securities Act of 1933, as amended (such Act being herein called the "Act" and any such person being herein sometimes called an "Indemnified Party"), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject under any statute or at law or in equity or otherwise, and shall reimburse any such Indemnified Party for any legal or other expenses incurred by it in connection with defending any actions, but only to the extent that such losses, claims, damages, liabilities or actions arise out of or are based upon (i) an allegation or determination that the Bonds, the obligations of the Issuer under the Indenture or this Remarketing Agreement, or the obligations of the Bank under the Letter of Credit should have been registered under the Act or the Indenture should have been qualified under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Disclosure Statement or any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but the Issuer shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuer by the Remarketing Agent specifically for use in connection with the preparation thereof, or if the person asserting any such loss, claim, damage or liability purchased Bonds from the Remarketing Agent, if delivery to such person of the Disclosure Statement or any amendment or supplement to it would have been a valid defense to the action from which such loss, claim, damage or liability arose and if the same was not delivered to such person by or on behalf of the Remarketing Agent. This indemnity agreement shall not be construed as a limitation on any other liability which the Issuer may have to any Indemnified Party. Notwithstanding the foregoing, this indemnification shall not cover any losses, claims, damages or liabilities caused solely by the negligence of the Indemnified Party or solely by breach of this agreement by the Indemnified Party.

(b) The Remarketing Agent shall indemnify, protect, defend and hold harmless the Issuer, and each of its directors, officers, agents or employees and each person who controls the Issuer within the meaning of Section 15 of the Act (for purposes of this paragraph (b), an "Indemnified Party") against all losses, damages or liabilities, joint or several, to which such Indemnified Party may become subject under any statute or at law or in equity or otherwise, and will reimburse any such Indemnified Party for any legal or other expenses incurred by it in connection with defending any actions, insofar as such losses, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Disclosure Statement or any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but only with reference to written information, if any, relating to the Remarketing Agent furnished to the Issuer by the Remarketing Agent specifically for use in the preparation of a Disclosure Statement. The Issuer and the Remarketing Agent agree that any statements set forth in the Official Statement or a future Disclosure Statement furnished in writing by or on behalf of the Remarketing Agent for inclusion in such documents shall be contained in a subsection entitled "Remarketing of Bonds" and that the Remarketing Agent's indemnification pursuant to this paragraph (b) shall be limited to such Section. This

4

indemnity agreement shall not be construed as a limitation on any other liability which the Remarketing Agent may otherwise have to any Indemnified Party, but in no event shall the Remarketing Agent be obligated for double indemnification. Notwithstanding the foregoing, this indemnity shall not cover any losses, claims, damages or liabilities caused solely by the negligence of the Indemnified Party or solely by breach of this agreement by the Indemnified Party.

(c) An Indemnified Party (as defined in paragraph (a) or paragraph
(b) of this Section 7) shall, promptly after the receipt of notice of the commencement of any action against such Indemnified Party in respect of which indemnification may be sought against the Remarketing Agent or the Issuer, as the case may be (in either case the "Indemnifying Party"), notify the Indemnifying Party in writing of the commencement thereof. In case any such action shall be brought against an Indemnified Party and such Indemnified Party shall notify the Indemnifying Party, the Indemnifying Party may, or if so requested by such Indemnified Party shall, participate therein or assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party of an election so as to assume the defense thereof, such Indemnified Party shall reasonably cooperate in the defense thereof, including without limitation, the settlement of outstanding claims, and the Indemnifying Party will not be liable to such Indemnified Party under this Section 7 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation incurred with the consent of the Indemnifying Party, which consent shall not be unreasonably withheld; provided, however, that unless and until the Indemnifying Party assumes the defense of any such action at the request of such Indemnified Party, the Indemnifying Party shall have the right to participate at its own expense in the defense of any such action. If the Indemnifying Party shall not have employed counsel to have charge of the defense of any such action or if any Indemnified Party shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to the Indemnifying Party (in which case the Indemnifying Party shall not have the right to direct the defense of such action on behalf of such Indemnified Party), legal and other expenses incurred by such Indemnified Party shall be borne by the Indemnifying Party. Notwithstanding the foregoing, the Indemnifying Party shall not be liable for any settlement of any action or claim affected without its consent, which consent shall not be unreasonably withheld.

(d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in paragraph (a) or (b) of this Section 7 is due in accordance with its terms but is for any reason held by a court to be unavailable from the Issuer or the Remarketing Agent on grounds of policy or otherwise, the Issuer and the Remarketing Agent shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) to which the Issuer and the Remarketing Agent may be subject (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer on the one hand and the Remarketing Agent on the other from the remarketing of the Bonds or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer and the Remarketing Agent in connection with the failure to register or qualify certain instruments as described in Section 7(a)(i) or in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Issuer on the one hand and the Remarketing Agent on the other shall be deemed to be in the same proportion as the aggregate principal amount of the Bonds remarketed pursuant to this Agreement bear to the total remarketing fees received by the Remarketing Agent. The relative fault of the Issuer on the one hand and of the Remarketing Agent on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

(e) The Issuer and the Remarketing Agent agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph.

5

Notwithstanding the provisions of this Section 7, (i) the Remarketing Agent shall not be required to contribute any amount in excess of the remarketing fee applicable to the Bonds remarketed pursuant to this Remarketing Agreement; and
(ii) no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation.

(f) The indemnification and contribution obligations of all parties to this Remarketing Agreement contained in this Section 7 shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of the Remarketing Agent, by or on behalf of any person controlling the Remarketing Agent or by or on behalf of the Issuer or (ii) any termination of this Remarketing Agreement.

(g) For purposes of this Section 7, each person who controls the Remarketing Agent within the meaning of Section 15 of the Act shall have the same rights as the Remarketing Agent and each person who controls the Issuer within the meaning of Section 15 of the Act shall have the same rights as the Issuer. Any party entitled to contribution shall, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder.

SECTION 8. FEES AND EXPENSES. In consideration of the Remarketing Agent's services under this Remarketing Agreement, the Issuer will pay the Remarketing Agent an annual amount equal to one eighth of one percent (1/8 of 1%) of the aggregate principal amount of Bonds outstanding under the Indenture, payable semi-annually in arrears on the first Business Day of each January and July commencing in July, 1999, and computed on the basis of the aggregate principal amount of the Bonds then outstanding. The Issuer also will pay all expenses in connection with the preparation of any Disclosure Statement and the registration of the Bonds and any other documents relating to the Bonds under any securities laws, qualifying the Indenture under the Trust Indenture Act and will reimburse the Remarketing Agent for all its direct out of pocket expenses incurred by it as Remarketing Agent under this Remarketing Agreement and the Indenture, including counsel fees and disbursements. This expense reimbursement obligation shall not be construed as covering the expenses of the initial issuance of the Bonds.

SECTION 9. DEALING IN BONDS BY TENDER AGENT, BANK AND REMARKETING AGENT. The Tender Agent, the Bank or the Remarketing Agent, in their respective individual capacities may in good faith buy, sell, own, hold and deal in any of the Bonds, and may join in any action which any Bond owners may be entitled to take with like effect as if it did not act in any capacity hereunder. The Tender Agent or the Remarketing Agent, in their respective individual capacities, either as principal or agent, may also engage in or be interested in any financial or other transaction with the Issuer, and may act as depository, trustee or agent for other obligations of the Issuer as freely as if it did not act in any capacity hereunder.

SECTION 10. INTENTION OF PARTIES. It is the intention of the parties hereto that no purchase, sale or transfer of any Bonds, as herein provided and provided in the Indenture, shall constitute or be construed to be extinguishment of any Bonds or the indebtedness represented thereby or the reissuance of any Bonds.

SECTION 11. FAILURES. The Remarketing Agent will not be liable to the Issuer, the Trustee, the Tender Agent or the Bank on account of the failure of any person to whom the Remarketing Agent has sold a Bond to pay for such Bond or to deliver any document in respect of the sale. It is understood and agreed that the Remarketing Agent shall not be obligated to advance its own funds to purchase, or to effect the purchase of, any Bonds.

SECTION 12. REMARKETING AGENT'S PERFORMANCE.

(a) The duties and obligations of the Remarketing Agent as Remarketing Agent shall be determined solely by the express provisions of this Remarketing Agreement and the Indenture, and the Remarketing Agent shall not be responsible for the performance of any other duties and obligations than as are specifically set

6

forth in this Remarketing Agreement and the Indenture, and no implied covenants or obligations shall be read into this Remarketing Agreement or the Indenture against the Remarketing Agent.

(b) The Remarketing Agent may conclusively rely upon any notice or document given or furnished to the Remarketing Agent and conforming to the requirements of this Remarketing Agreement or the Indenture and shall be protected in acting upon any such notice or document reasonably believed by it to be genuine and to have been given, signed or presented by the proper party or parties.

(c) The Remarketing Agent shall not be liable for any actions taken or omitted to be taken pursuant to this Remarketing Agreement, except for its own gross negligence or willful misconduct.

SECTION 13. TERMINATION. This Remarketing Agreement will terminate upon the retirement of the Bonds or the effective resignation or removal of the Remarketing Agent as Remarketing Agent in accordance with the Indenture. The Remarketing Agent will resign as Remarketing Agent under the Remarketing Agreement if requested to do so by the Issuer in writing and may resign at any time. Following termination, the provisions of Section 7 hereof will continue in effect, and each party will pay the other any amounts owing at the time of termination.

SECTION 14. MISCELLANEOUS.

(a) Except as otherwise provided, any notice or other communication herein required or permitted to be given shall be in writing or by telex or facsimile transmission or by telephone with subsequent written confirmation and may be personally served or sent by United States mail, first class postage prepaid, and shall be deemed to have been given upon receipt by the party notified.
